Cord Blood Banking Market Technological Innovations And Future Opportunities 202 – Fractovia News

Saturday, November 7th, 2020

Global cord blood banking market has emerged as one of the most crucial niche verticals of the healthcare industry, driven by the product demand in treatment of many life-threatening diseases including leukemia, thalassemia, and different kinds of cancers. As per The American Academy of Pediatrics, more than 30,000 stem cell transplants had been performed using cord blood by 2013, essentially demonstrating the criticality of stem cell cord blood banking institutions in treating fatal disorders with fewer complications and enhanced medical outcomes.

Apart from affirmative policy statements and legislative provisions, the public cord blood banking market is gaining traction due to the fact that some nations such as Italy and France do not permit the establishment of private cord blood banks. Furthermore, an increasing number of funding programs by regional governments to overhaul stem cell cord blood banking research is augmenting the public cord blood banking industry. In fact, as per a research report by Global Market Insights, Inc., the revenue share of public cord blood banking industry is slated to exceed USD 3,931 million by 2025.

One of the main factors supporting the growth potential of public cord blood banking industry is the establishment of legislative provisions that ensure discoveries in the field of regenerative medicine and cellular therapy. In this regard, the Stem Cell Therapeutic and Research Act was established in the U.S. Senate and House Representatives during the year 2015.

India cord blood banking market has registered commendable gains due to the efforts undertaken by various NGOs spread across the country to offer funding for a public cord blood banks, in order to make stem cells available to the Indian population at an economical rate.

Some of the prominent companies in the industry globally include Cordlife, Global Cord Blood Corporation, Singapore Cord Blood Bank, and Jeevan Stem Cell Foundation, among many others.

A considerable increase in the number of patients diagnosed with life-threatening genetic disorders is a major factor supporting enhancements in cord blood banking industry. According to the World Health Organization, approximately 1 in 2000 newborn babies in the European Union are affected by cystic fibrosis. With the increasing prevalence of genetic disorders, the need for cord blood banking is likely to witness enormous growth in the future.

Ashley Cain fights back tears as he reveals 12-week-old daughter will need bone marrow transplant in – The Sun

Saturday, November 7th, 2020

ASHLEY Cain fought back tears as he revealed that his 12-week-old daughter Azaylia will need a bone marrow transplant regardless of how well her chemotherapy goes.

The 30-year-old star told fans that his baby girl had been diagnosed with Leukaemia last month - just eight weeks after he and girlfriend Safiyya Vorajee welcomed her into the world.

The devoted dad has been keeping fans updated on Azaylia's battle on Instagram, and couldn't hide his upset as he bravely detailed their latest "crushing blow".

Speaking from his daughter's hospital room while she slept, Ashley said: "I was having a great morning with my little one then the doctors came in and said that no matter how well she does with these blocks of chemotherapy, she's on the high risk list so she'll 100% need a bone marrow transplant.

"And due to her ethnicity, Caribbean, Burmese, Indian, English, it's very difficult to find a match for a transplant.

"Even if she does find a transplant, she's so small and because her case is so bad it's a very, very long, gruelling, and intense procedure and we could be here for a very, very long time - and that's if she manages to fight it and withstand it."

With his eyes filling with tears, Ashley continued: "It's sad, it feels like we are back to the start - it's broken my heart again.

"It's difficult, it's so difficult. As long as she has a fighting chance we are going to fight and this little warrior, she can do it."

He added: "Please keep us in your thoughts and prayers and please keep sending us positive energy because we are feeding off it."

The star shared some more detail in the video's caption, writing: "Her case is very rare and aggressive and made even rarer by her age.

"The bone marrow transplant it is a very long and gruelling process of intense chemotherapy, stem cell treatments, transfusions etc and there are many high risk complications.

"I cant lie its a crushing blow as shes in the high risk category and this process is incredibly enduring on her little body. But as always were keeping things positive and as long as shes got a fighting chance WE WILL FIGHT!"

On his Instagram Story, Ashley shared heartbreaking videos of his little girl giggling in her bed, while explaining that she is starting to lose her hair due to gruelling chemotherapy.

The Ex On The Beach star previously called his baby his "little soldier", telling fans: "As long as there's a glimmer of hope, it doesn't matter how much or how little, we will hold on to that and use that to fuel us to the stars and back."

And sharing the devastating news of his newborn's diagnosis in October, Ashley had written: "Yesterday I had to go through something no parent in the world should have to go through.

"The single most upsetting, terrifying and heartbreaking experience I have ever been through. I found out my beautiful daughter Azaylia Diamond Cain got diagnosed with a very rare and aggressive form of leukaemia, which has come with many complications.

"Everybody who wishes to, please say a prayer for my beautiful brave little girl Azaylia who is currently fighting a battle for her life!

‘We’re truly blood brothers’: Stanford coach David Shaw and his recent fight to save his brother, Eric – KGO-TV

Saturday, November 7th, 2020

David Shaw walks into the hospital room and takes a seat next to the bed. He does this nearly every day, right around lunchtime.

He looks at his younger brother, Eric, tubes snaking across his arms, machines beeping and whirring. Eric does not look like Eric anymore, his skin darkened, scars deepened, features altered. They both know this but never mention it.

Eric is dying, a rare, aggressive skin cancer rampaging through his body with such ferocity that his doctors are nearly out of options. Radiation failed. Chemotherapy failed. Two bone marrow transplants failed.

As Stanford's head football coach, David Shaw is relied on to always know what to say, how to say it and when to say it; but he cannot find the words now that he and his brother are staring down what seems to be an inevitable fate.

"What do you say, where you think you've pulled at the last thread and there are no more threads?" David said. "All I could tell him was that I loved him and that I was there for him. The rest of it was really just ... I thought it was only a matter of time before he passed away."

Two years later, what happened between David and Eric remains real, present and raw -- changing their entire relationship, redefining what it means to be a brother. The words are still difficult to say, so they tip-toe around the crushing physical and mental toll Eric's cancer took on them.

David and Eric are sure to think about it all this weekend, when Stanford opens its season at Oregon on Saturday. Because the last time the Cardinal visited Eugene, neither one knew whether Eric would live or die.

After Stanford came from behind to win that game 38-31 in overtime, David delivered a message at the end of his postgame television interview, looking at the camera and saying, "To my brotherEric: I love you." He tapped the lime green pin on his black Stanford sweatshirt before he left the screen.

When Shaw became head coach at Stanford in 2011, it was the culmination of a family journey. His father was a longtime coach there; David played receiver for the Cardinal and eventually returned as an assistant under Jim Harbaugh. The entire Shaw family -- parents Willie and Gay, along with David, Eric and their sister, Tawnya -- all call the Bay Area home.

To this day, David says the day he was introduced as coach was "one of the better days in all our lives."

Yet something started to happen to Eric that no one could quite figure out. That same year, Eric found strange looking spots on his torso. His wife, Crystal, noticed the first one under his arm. Maybe it was eczema, they thought. Then the spots started to spread. He went to the doctor. They prescribed an ointment, but the spots kept popping up, until they covered his entire body. Eventually, tumors started to grow. It looked as if someone had pushed marbles under his skin. Doctors remained confounded. Eric itched uncontrollably, insatiably. His skin itched so badly, it became difficult to put on clothes, shower, sleep and go to work. He eventually needed sleep medication so he could get uninterrupted rest.

Even then, he itched subconsciously, only realizing what happened when he woke up in the morning to find his arms and sheets covered in blood. Some nights, he tried to sleep on his forearms so his body wouldn't touch the sheets, because his skin grew too sensitive to any touch. At one point, he had more than 30 open wounds on his body.

"It's something that's so pervasive and so destructive that a lot of people have mental problems -- you can't do anything without extreme pain," Eric said. "You bleed a lot through the tumors, through the lesions, through the scratching. A lot of people don't survive, really, because of the mental stress that comes with it."

Doctors had a hard time diagnosing his disease because it is often confused with psoriasis, eczema or other skin conditions. Eventually, they determined he had a rare form of skin cancer called mycosis fungoides, a type of T-cell lymphoma that affects one in 6 million people in the United States and Europe. At the time, Eric Shaw was 38.

In 2013, he and Crystal pushed for a referral to Stanford Cancer Center, which has leading experts in the disease. Mycosis fungoides is so rare, it accounts for only 4% of all non-Hodgkin lymphoma cases; among those who suffer from it, only 20% have the type of itching Eric experienced. Rarer still is to find it in people under the age of 40, and African American men often end up with the worst prognosis. All the odds were firmly against him.

"When you first hear skin cancer, your mind doesn't go too far," David said. "So initially I was like, 'There are creams and other minor surgeries. I think it'll be OK.' And then Eric said, 'No, this is not the typical skin cancer. This is inside my body. This is inside the layers of my skin, and it's not one spot. It's everywhere.'

"I didn't really get it for weeks after that because, rectifying something that I didn't think was so serious to [then thinking] ... 'Oh my gosh. So this is really cancer. This is really scary now.' It took a long time for that to sink in."

David turned it over in his mind. He was the big brother, the protector, the one who always made sure Eric would be OK. They were supposed to raise their kids together, grow old together, and reminisce about the randomness of a life spent together.

He kept coming back to one thought: You're not supposed to lose your little brother.

David and Eric Shaw grew particularly close as children as they moved from place to place when their father, Willie, took new coaching jobs. Tawnya, their older sister, fit in anywhere socially. But David and Eric, who is two years younger, stuck together.

"Like a pair," David said.

They loved riding their bikes and, when they moved to Arizona, they took advantage of the wide-open spaces in the new development where they lived. They rode for miles and miles, setting up their own ramps and doing tricks and wheelies, visiting friends along the way before returning home after dark. They played sports, too, and though David loved football as much as their dad, the basketball court is where the brothers had their epic battles.

"I was always kind of a little bit stronger and I'll never forget the last time we played one-on-one basketball," David said. "He just got better than me, and he won, and once I got over the anger and disappointment, I was proud because my younger brother had grown and was gaining confidence."

Said Eric: "I wanted nothing more than to beat him, and he wanted nothing more than to keep beating me. But, during those times, it was just us, it was me and him. He was my best friend."

David went on to play at Stanford and eventually got into coaching, against his mother's best wishes. Eric did not pursue a career in athletics. He went to San Diego State and got into a career in marketing at a financial services company, where his gregarious nature, big smile and easy laugh made him a perfect fit. Though their personalities are different -- David is stoic and introspective, Eric makes anyone feel as if they have been friends forever -- they are grounded in the same values they learned at a young age: family and faith above everything else.

Those principles only grew stronger after they found themselves in the Bay Area as adults.

After David was hired by Stanford, the entire Shaw family made it clear it would always be around to support him. Family members all have a standing invitation to come for dinner on Tuesdays. And they always attend home football games, waving and hugging David during the team's pregame walk, cheering from the stands, and then waiting for some time together once the game ends.

Even as Eric grew sick, he made it a point to go cheer for his big brother. "It's not just the football game. Our family comes together," he said. "We celebrate, we come to watch the game and cheer the team on and support David. And then afterwards, win or lose, we all wait for him to come out. It's a family day. It's been wonderful to share that experience with David."

Stanford eventually drew them even closer, and it had nothing to do with football.

Eric did not understand the gravity of his situation until his first meeting in 2013 with the doctors at Stanford Cancer Center. They put it bluntly: He had such an aggressive form of the disease that he needed immediate treatment. They would start with total skin radiation, preparing Eric to lose his hair, eyebrows, eyelashes, fingernails and toenails.

If that did not work, they would try chemotherapy next.

"All these thoughts are running through your mind," Crystal said. "'Is he going to make it? Is it going to work? What's going to happen?' At the time, our youngest daughter was 3 months old, so it was pretty overwhelming. We were just putting our lives together and then boom: you're in the middle of this cancer war."

The next week, Eric took a leave of absence from work and began four-times-a-week trips from their home east of Palo Alto, California, to Stanford Hospital, often driving as many as three hours one way in traffic. When he arrived, he went into a box and his whole body was exposed to the radiation light for about an hour. Then, he would make the drive back home to see Crystal and their four kids -- Caleb Michael, Jared Spann-Shaw, Madison Shaw and Olivia Shaw.

The radiation charred his skin. He lost weight. When he looked in the mirror, Eric no longer recognized the man looking back at him.

"Nothing prepares you for something like this," he said. "Knowing that other people were looking at me and knowing that something was very wrong, that was a daily grind to get myself up out of bed and get ready for the day, knowing that that was going to be my life."

He did this for three straight months, all to keep the disease from growing to a point where it would kill him. It worked for a short time, but the disease came back more aggressively six months later. Doctors moved on to chemotherapy treatments, some of them experimental, but also began discussing the last-resort option: a bone marrow transplant.

David and Tawnya immediately volunteered to become donors, and underwent testing. In most cases, siblings are the best chance at a donor match. Unfortunately, in their case, neither was close. On a 10-point match scale, Tawnya registered a 3, David a 5. Neither qualified to donate.

"I wanted to jump to the front of the line and say, 'Whatever I have to do, whatever you have to take out of me, however you have to do it, just do it,'" David said. "For them to come back and say that you're not a strong enough match was disheartening. It hurt me. The fact that we had to put our trust and faith in people that we didn't know, and that we're going to have to go out to registries and try to find someone who was a better match than I was, that uncertainty, and that doubt, it's hard to keep it at bay at that point. It starts to creep in."

Doctors eventually found two donors whom they believed could work, but they were not perfect matches. In early 2018, Eric and his family moved into a two-bedroom apartment near Stanford Hospital to prepare for the transplant. For three months, he went through radiation, then chemotherapy to prepare his body to accept the donor cells.

He underwent the transplant in April, feeling confident and inspired it would work. After a month, doctors did an initial check to see how many of the donor cells had survived the transplant.

None survived.

"It was like I never even had the transplant," Eric said. "That was so devastating. We just knew it was going to work. I mean, we're people of faith, and we knew everybody was praying for us, and that we were praying that this six-year journey was going to finally be over. And it wasn't over. It was crushing for them to say, 'It didn't work. We're going to have to try again.'"

The second attempt happened in September. Crystal bought lime green pins for the family to wear for lymphoma awareness. Without telling Eric or Crystal, David decided he would wear his on his shirt for the 2018 football season. In addition to that, he had lime green and yellow ribbons placed on the back of Stanford helmets as a way to show support for both cancer patients and cancer survivors.

He told his team that his brother was fighting cancer, and briefly mentioned the helmet ribbons publicly during an early-season news conference. But beyond that, David kept the severity of what was happening to his brother to himself, masking his growing nervousness, fear and anxiety as the clock ticked toward the next transplant. He had a hard time processing what was happening. He did not want to put that at the feet of his players, or his staff.

The doctors used the same donor cells that failed the first time for the second transplant on Sept. 11, 2018, because that was the only option available. But this time, doctors used even stronger drugs to prepare Eric's body to receive the donor cells -- hoping that would do enough to stop his immune system from attacking them.

When Stanford played Oregon on Sept. 22, no one in the Shaw family knew whether the transplant had worked. But the situation was more dire than the first transplant. The stronger chemotherapy caused major complications, and Eric became severely ill.

David coached the game with this in the back of his mind. Stanford rallied from a 21-7 deficit to win an overtime thriller, moving to 4-0 on the season, with a top-10 matchup against Notre Dame the following week. Back in Palo Alto, Eric watched the entire game alone in an apartment he rented near the hospital, the comeback buoying his spirits.

He had no idea his brother would speak to him through the television until he heard the words, "To my brother Eric ..."

"In that moment, I didn't feel any sickness at all," Eric said. "I can't really describe what I felt, just how proud I am of him and how awesome it made me feel that he would do that for me."

Said David: "If that transplant didn't work, I didn't know how many more games he was going to be able to see. That was an opportunity for me on national TV to speak to him, to say to my brother that against the odds, we came back and throughout the entire game, I was thinking about him."

Eric soon returned to Stanford Hospital. The chemotherapy destroyed his blood system, so he needed daily blood transfusions to stay alive. It came as no surprise when doctors told him the second transplant had failed. They had no plan now, no other donor options. David came by to visit as often as he could, but he had a hard time finding the words to say to his dying brother.

"I thought about Crystal. I thought about their kids," Shaw said. "I thought about, 'How can we help?' And then I kept going, 'We just can't get there. There has to be something else.' And we all prayed and we all comforted each other and trusted the doctors and prayed for the doctors. And just kept saying, 'Just tell us whatever options there are. Just tell us what to do and we'll do it.'"

During the day, Eric had his mother, Crystal, David, or David's wife, Kori, at his side, helping to keep his mind off what was happening to him. But in the evenings, when he was alone in his hospital room, he couldn't help but think about the dwindling medical options and his own death, slowly accepting what he believed would inevitably come.

Over seven years, everything the doctors tried had failed, and the disease always came back more aggressively. He felt exhausted in every possible way, desperate to feel better. He didn't want to die. All he wanted to do was get better, and see his kids again, hug his wife and go home. But that possibility seemed as far off as the stars.

"The doctors couldn't help us," Eric said. "They had lost all hope. There was nothing left, but we were in the deepest part of the valley, and there was nobody there but God. I said, 'You're going to take me off this Earth.' And he told me, 'Eric, you're not going to die.' That was the point at which my faith really took over, and I really had true peace."

His team of doctors huddled together again and came up with a plan many of their colleagues questioned, simply because they had never attempted it. In mid-October of 2018, they told Eric they wanted to try a third transplant.

Only this time, they wanted David to be the donor and they had only weeks to make it happen.

Eric thought, "Are they trying to kill me?"

When David was initially rejected, doctors had worked for 25 years to find a way to do half-match transplants but had virtually no success. By 2018, doctors explained that a different way to do the transplant had emerged, opening up the potential to try it with Eric. These transplants, called haploidentical transplants, typically use donor cells from a family member.

Dr. Wen-Kai Weng, Eric's bone marrow transplant physician, explained, "It was relatively new at this time. We decided to go ahead, because we knew if we didn't do it, the disease would really come back with a vengeance."

No one had ever done a third transplant with donor cells at Stanford.

"If he didn't go for this risk, he wouldn't be here," said Dr. Youn Kim, who treated Eric and heads Stanford's multidisciplinary Cutaneous Lymphoma Clinic/Program. "He wouldn't be living."

Doctors told Shaw there was a 15% chance he would not survive the transplant itself. If he did survive it, there was only about a 30% to 40% chance the donor cells would work. Compared to much steeper survival odds with no transplant at all, the decision -- filled with multiple layers of danger -- did not feel risky at all.

They had to try.

"They might have told us what the odds were, and I honestly just pushed it out of my brain," David said. "If this is the Hail Mary, hey, we're going to drop back and throw it as far as we can and send prayers along with it and hope that it works."

Without hesitation, David said to his brother, "Tell me what I need to do."

Stanford gathered in its team hotel early on Oct. 27 to begin final preparations before hosting Washington State later that day. David checked in for a 9 a.m. meeting and when it finished, he checked out of the hotel without saying a word. He walked toward the back exit, careful to make sure no one saw him, and snuck out the door to a waiting car.

Shaw sat in the passenger seat, headed toward campus and Stanford Hospital, praying all the while that what he was about to do would work.

He arrived at the hospital and was hooked up to an IV for the first dose of medication. This would not be the more traditional bone marrow transplant, where cells are extracted with a needle through the hips. Rather, the medication flowing through the IV would stimulate his body to overproduce the stem cells needed for the transplant, flooding his blood with them. The cells would then be extracted from his blood, and transplanted into Eric.

Doctors told him to expect to start feeling joint pain and tiredness within 24 hours. Those symptoms would grow only stronger over the coming days, when he came in for more medication. They told him he should stay off his feet, rest and remain hydrated.

That would be nice, David thought. But he had a game to coach. Only two people inside the program knew he had gone that morning: assistant athletic director for football operations Callie Dale, who drove him to the hospital, and defensive coordinator Lance Anderson.

"The way that I do my job, I work really hard not to make it about me," David said. "Although I wanted my team to know what my family was going through, college football is about the student-athletes. I wanted them to focus on what they needed to do. I didn't want to pull from that. I didn't want to, all of a sudden, now make it about me and my family."

A few hours later, he returned to the team hotel and acted as if he had been there the entire day, speaking nothing about his trip to the hospital. Shaw put on his lime green pin and made his way toward the bus. The short ride to the stadium felt long that day. His mind wandered before returning to the flip card in front of him.

As he exited the bus and finished the walk to the stadium, his two young nieces ran up to him. They squeezed him, holding on longer than usual, as if they knew their Uncle David was their only option, too.

He worried players would notice him moving around so slowly. If they did, no one said a word. Shaw kept pushing the pain aside, shoving his emotions down deep, saying prayers every chance he got.

On Wednesday, Shaw woke up and was so lethargic, he felt as if he was moving like a sloth. He went to the hospital for the final procedure: extracting the cells from his blood. Shaw wore comfortable clothes, arranged his pillows and settled in for a long day ahead. Doctors hooked him up to a machine that would do the work through two IVs: One took his blood so the needed donor cells could be siphoned out; the other IV would put the blood back in his body.

Eric rested on another floor in the same hospital.

David worked on his game plan, watched a few movies and occasionally stared at his own blood in the IVs, willing it to save his brother. He kept saying to himself over and over again, "God, I hope this works."

After eight hours, he was finished. Shaw then went out to practice.

"I remember walking up to him and just asking him, 'How are you doing, how are you feeling?'" Anderson said. "I could see it in him that he wasn't his normal self. He paused for a little bit and then he's like, 'I'm OK. A little bit tired, but I'm OK.' You know, just trying to put the most positive light that he could on it."

The next day, Nov. 1, 2018, Shaw went back to the hospital. It was transplant day, and he had to be with Eric to witness what they hoped would be a miracle. David and Crystal watched as Eric received a transfusion of David's stem cells, a shimmering light pink fluid flowing into his body. They sang and prayed. Already, they had received one small bit of good news: Doctors extracted 28 million cells from David's blood, about 20 million more than what they had hoped to get.

Stanford traveled the following day to Seattle, for a game against Washington. David felt guilty for leaving, but he knew there was nothing else he could do. Eric struggled in the hospital, not only from the transplant, but from the heavy chemo and radiation doctors used to prepare his body for the new cells.

Eric ran a fever of 105 degrees and vomited for days. The pain grew so intense he was put on a morphine drip and was in and out of consciousness. In Seattle, Shaw remembers being locked into the game, "except for those little moments where my heart was with my brother."

Stanford lost another heartbreaker, 27-23.

"I know us losing had nothing to do with everything David was going through," Dale said. "But just piling that on with everything else he was dealing with, it was a lot for him. He brought that up many times, about how Eric would tell him the biggest excitement for him every week was watching us play and watching us win. I know David had a lot of pressure on himself, amongst the pressure he already has as a head coach, to win for Eric. And I know that every time he did, he really felt like it was for him. And when we came up short, I know he was probably even harder on himself than he normally would have been."

Back at Stanford, David visited Eric when he could. But the waiting game took an increasing mental toll. David prides himself on his ability to compartmentalize, to focus on the only thing in front of him. He never spaces out, and he rarely gets emotional. But Shaw was falling apart on the inside.

He often found himself staring at cut-ups of red zone plays, not realizing the film had been paused for 20 minutes while his mind drifted off. Whenever that happened, he would stop and call someone, either his brother, his wife, his mother or Crystal just to see how they were doing.

"There were times where I thought life was slow motion, but it was actually moving and I was the one who was in slow motion," David said. "I found myself sometimes saying, 'Is this real? Is this really happening? This shouldn't happen.'"

In the middle of every single meeting, in the middle of every single film session, he silently prayed, "God help my brother. Just please let this one work."

"I look back now and I know more of everything that was going on and the situation," Anderson said. "I realized how much he was dealing with and how much he had to bear that week. And it's amazing that he was able to go through that week without really letting any of us really know exactly what he was going through and what a big deal this really was."

Within a few weeks, Eric started to turn a corner. Though they did not know whether the transplant had worked just yet, he showed enough improvement to leave the hospital after 52 days. David arrived for the big day, and Eric slowly put on a protective mask before shuffling to a waiting wheelchair. Doctors, nurses and support staff lined the hallway, clapping and cheering.

David cries when recalling that moment, his pent-up emotions flooding out as he describes it publicly for the first time.

"This is my little brother, after years of cancer, getting to leave the hospital," Shaw said, his voice quavering. He pauses to wipe tears from his eyes. "The nurses were crying. The doctors were crying. Because a few months earlier, they were preparing us for him to die. And he got to go home."

Three days later, doctors met with Eric and Crystal to deliver the results from the transplant. After only 27 days, Eric had none of his own blood coursing through his body.

It was all David's.

Eric picked up the phone.

"Dave," Eric said. "You have a twin. We're truly blood brothers."

Eric, who turns 46 on Friday, has lived a fairly normal life since he was declared cancer free on Jan. 1, 2019, although the coronavirus pandemic has limited how often the Shaw family can see each other.

In September, they decided to get together to celebrate all of their recent birthdays at David's house. They stayed outdoors, socially distanced, with masks on. Eric and David allowed themselves a hug, their heads turned to the side.

"Every time I see him, I just smile, you know? Because he gets to be here," David said.

CA Prop 14 Explained: What To Know Before You Vote Election Day – Los Angeles, CA Patch

Saturday, November 7th, 2020

LOS ANGELES, CA Proposition 14, the only statewide bond measure on the general election ballot, asks voters to authorize $5.5 billion in bonds to fund stem cell research. If that sounds familiar, that's because it is. California approved a similar bond request 16 years ago, allowing the state to prop up what was then a fledgling and controversial area of research.

Prop 14's supporters contend the money is needed to fund cutting-edge research on the brink of discovering treatments and cures that could help save countless lives. Opponents say such promises are "shameless exaggerations" and that California isn't in a position to spend billions on stem cell research.

In 2004, Californians authorized $3 billion in bonds to create the California Institute for Regenerative Medicine, with the aim of making the Golden State a hub of cutting-edge stem cell research. It offset the George W. Bush administration's decision to halt federal funding for embryonic stem cell research. Sixteen years later, the California Institute for Regenerative Medicine is running out of money, forcing it to suspend new projects. Last year, the institute stopped accepting new applications, according to Ballotpedia.

If Prop 14 passes, it will authorize $5.5 billion in state general obligation bonds to support private, university and nonprofit stem cell research and therapy for diseases and conditions such as cancer, HIV/AIDS, Alzheimer's, Parkinson's, strokes, epilepsy and other neurological conditions. In addition to funding research, the measure would help fund treatment and physician training.

The measure caps the California Institute for Regenerative Medicine operating costs at 7.5 percent of the funding, with the rest going to grants. Over the last decade, the bulk of the institute's grants went to California universities and hospitals. It will cost the state about $260 million a year for 30 years to repay the bonds.

According to the text of the measure, the institute has generated more than $3 billion in matching funds, sponsored more than 1,000 research projects and treated thousands of patients. It claims to have promising treatments in the pipeline awaiting funding for final stages of research.

"This medical revolution holds the promise of restoring health and quality of life for many of California's individuals and families suffering from chronic disease and injury," Robert Klein, chairman of Americans for Cures, told the California Stem Cell Report blog. "However, the last tactical mile to bring this broad spectrum of therapies to patients will require more funding and the thoughtful support of California's public as the human trials and discoveries are refined and tested, overcome numerous obstacles or complications, and ultimately serve to improve the life and reduce the suffering of every one of us."

Opponents of the measure say that the California Institute for Regenerative Medicine is no longer necessary because the federal government now spends billions to support stem cell research and private entities are leading the way on advancements without the help of taxpayer-funded grants. They question the institution's track record, oversight and budget.

"We can't afford to waste billions. In the middle of an economic crisis, with soaring unemployment and budget shortfalls in the tens of billions of dollars, we don't have money to burn," reads the opposition on the Official Voter Information Guide. "Paying back Prop. 14's costs of $7.8 billion could mean huge tax increases at a time when our economy is on its knees. Or laying off thousands of nurses and other heroes who do the real work of keeping California healthy."

The measure has the support of the California Democratic Party and the University of California Board of Regents. More than $9 million has been spent on the Yes On 14 campaign, while there are no official opposition campaigns. However, several newspaper editorial boards have come out against the measure including The Orange County Register, the Mercury News and The Bakersfield Californian.

The Many Model Systems of COVID-19 – The Scientist

Saturday, November 7th, 2020

Earlier this year, as transmission of SARS-CoV-2, the virus behind the COVID-19 pandemic, started to pick up speed, researchers around the world hurried to find model systems that could provide insight into disease spread, host immune responses, and possible treatments.

When the pandemic first started, nobody really knew what was going to be the best model, says Amanda Martinot, a veterinary pathologist at Tufts Cummings School of Veterinary Medicine.

The most widely available candidates were mice, which are easily housed and so well-researched that there are tons of tools available for studying nearly every aspect of their biology. But as researchers suspected, based on previous incompatibility of mice and other coronaviruses, the animals present challenges when it comes to studying SARS-CoV-2. The virus uses a human receptor called ACE2 to get into cells, but mouse ACE2 is different enough that the virus doesnt readily bind it.

Scientists have overcome the issue using two separate strategies: generating transgenic animals that express the human receptor and modifying the SARS-CoV-2 virus to make it better able to bind mouse ACE2.

Even with the success of those approaches, investigators have also been on the lookout for other options. Ferrets, for instance, are useful for studying viral transmission and viral replication in the upper respiratory tract and have been used by several groups for SARS-CoV-2 experiments. Some researchers have also turned to hamsters, which have been used in the past to study other viruses, including the coronaviruses responsible for severe acute respiratory syndrome and Middle East respiratory syndrome.

Hamsters are known in virology for their permissiveness to all kinds of viral infection really, and, as a rule of thumb, I would say if something doesnt work in a mouse, you may as well try a hamster, says Jakob Trimpert, a postdoc at the Free University of Berlin. And if youre lucky, it works there. Along with collaborators, hes been using several species of hamsters to study SARS-CoV-2 infections and potential therapeutics.

The hamster ACE2 receptor is compatible with SARS-CoV-2, and the animals develop clear clinical indicators of disease, he explains. For instance, Syrian hamsters(Mesocricetus auratus), one of the hamster species most commonly used in virus research worldwide, get mild SARS-CoV-2 infections, but their main symptomweight lossis reproducible and possible to measure. These animals also have severe pneumonia that is detectable via lung pathology. Trimpert and his colleagues used both transcriptomics and proteomics to evaluate the animals immune responses to SARS-CoV-2 in a study they published on July 20.

Many alveolar air spaces (white) are collapsed during a SARS-CoV-2 lung infection in a Syrian hamster (right). They are not collapsed in an uninfected hamsters lung (left).

Amanda martinot, tufts cummings school of veterinary medicine

Hamsters have been the best model so far for showing us any clinical disease, says Martinot. They develop weight loss, and they develop a fulminant pneumonia where its affecting sometimes over fifty percent of their lung, she adds. They also will recover if given time, but the pathology we feel is more representative of what you might see in humans. Martinot, Dan Barouch, who directs the Center for Virology and Vaccine Research at Beth Israel Deaconess Medical Center, and other collaborators recently published a study showing that a SARS-CoV-2 vaccine protected against weight loss and pneumonia in Syrian hamsters.

This species, also known as the golden Syrian hamster, has some drawbacks, too, Trimpert says. Theyre big, for one, weighing in at 150160 grams fully grown, in contrast to adult mice, which tip the scales at about 3035 grams. Syrian hamsters are also aggressive toward each other and sometimes the people taking care of them. Their size and aggression mean that they often have to be housed alone in larger cages, which makes them more expensive to keep.

The biggest issues, according to Trimpert, are the poor quality of the sequenced genomemany genes are just missingand the lack of molecular tools that work in hamsters. To circumvent these problems, Trimpert and his colleagues are resequencing and annotating the Syrian hamster genome.

Because the weight loss in Syrian hamsterstheir only easily observable clinical symptomis quite mild, its also a drawback, particularly when testing therapies or vaccines, Trimpert tells The Scientist. If you need thirty hamsters in order to get statistical significance . . . that is a huge practical problem.

The researchers are skirting this issue by beginning work with another species, Roborovski dwarf hamsters (Phodopus roborovskii), which are smaller than mice and less aggressive than Syrian hamsters. The dwarf hamsters also get much sicker than their larger relatives following SARS-CoV-2 infection, developing massive blood clots in the lungs, which are often present in severe cases of COVID-19 in people as well. Most of these hamsters eventually die of the complications of the infection, which, according to Trimpert, indicates that they might be a good model of severe disease in humans.

Joep Beumer

Getting a better picture of what is happening in people is a common goal. Eric Song, an MD/PhD student in Akiko Iwasakis lab at Yale School of Medicine, wanted to determine what effect SARS-CoV-2 was having on the brain. He and his colleagues used a humanized mouse model, in which a promoter drives the expression of human ACE2 in epithelial cells, in a study released as a preprint earlier this year. They found that SARS-CoV-2 could infect the central nervous system in the mice, but it still wasnt clear whether those findings translated to human patients.

To probe that question, the researchers turned to brain organoidscultured, miniature organs that resemble the developing brain and contain neuronal and glial cell types derived from human induced pluripotent stem cells (iPSCs). Not only did SARS-CoV-2 infect the organoids, infection also appeared to cause cell death, a finding corroborated by another study in brain organoids published by separate group September 23. Song and his colleagues also found antibodies against SARS-CoV-2 in the cerebrospinal fluid of people with COVID-19 and evidence of SARS-CoV-2 infection in the post-mortem brains of COVID-19 patients.

The team used three complementary methods to account for the limitations of each, Song tells The Scientist.There is room for all the different models that are in play, he adds. With human samples, you can only take really a snapshot of the sickest patients because thats the only time you will be getting a post-mortem sample, but combined with the mouse and the organoid model, youre able to study [the] kinetics and the dynamic process of viral invasion. Things like organoids really help us access tissues that we would not otherwise have access to.

Immunologist and developmental biologist Hans Clevers of Utrecht University in the Netherlands and colleagues are leveraging that access with gut organoids. Rather than deriving the organoids from iPSCs, though, they use multipotent stem cells taken from any adult epithelial tissue. In some ways the strategy is more limited: gut epithelial cells can only make mini guts, for instance, in contrast to iPSC-derived organoids, which can become lots of different tissues. On the other hand, they grow forever, Clevers says. iPSC-based organoids, you make them and then you have to use them for an experiment because they stop growing the moment you start specifying them.

His group published a study on July 3 investigating whether or not SARS-CoV-2 can target the gut, a hypothesis based on the expression of ACE2 in the intestinal lining and the gastrointestinal symptoms that many COVID-19 patients experience. Their work in human small intestinal organoids confirmed that the virus does enter the cells of the intestinal lining, replicate, and cause changes in gene expression.

Now, Clevers and his colleagues are using organoids to test possible COVID-19 therapeutics. Chloroquine is an example of a drug that looked promising for blocking SARS-CoV-2 infection when researchers tried it in conventional cell culturein that case, cells derived from African green monkey kidneys and grown in one layer on a dish, he says. But, as theyve shown in a new study thats been submitted for peer review, in the gut organoid model chloroquine is ineffective against SARS-CoV-2, just as it is in patients. According to Clevers, this latest finding indicates that an extra screening step in organoids following the identification of a promising drug in a traditional cell culture system could provide another layer of information before moving into preclinical animal models or the clinic.

Cell lines are cheap, they grow fast, and most robotic strategies for screening have been designed for cells growing in two dimensions, Clevers says. There are multiple efforts now around the world to come up with the machines to do similar high throughput screens with 3D. With the organoids, its a little bit more complex to analyze because theyre not flat, he explains, but the type of organoids they generate in his lab grow quickly. He predicts that organoids will come to be used more widely because their physiology recapitulates that of humans so well, but that theyll never replace animals.

Along with hamsters, nonhuman primates are one of the main models that researchers studying COVID-19 therapeutics use. SARS-CoV-2 readily infects primates, such as macaques, due to the compatibility of their ACE2 receptor, but they do not show disease symptoms, says Martinot. The nonhuman primate experience of COVID-19 seems to be most similar to the mildly symptomatic cases of most people who are infected, she adds. They develop regions of pathology in their lungs that are detectable with a microscope, but its not enough to make them sick, and observing that kind of disease in a person is unlikely because these animals are euthanized early in infection to allow researchers to track any changes.

It would be nice to have a primate model of severe disease, says Barouch. Nobody has been able to develop one so far, but models are always in development.

And symptom presentation isnt everything. These animals are harder to access and harder to house than rodents, but they are a wonderful model for vaccine research and for evaluating . . . the adaptive immune response to COVID-19, Martinot says, at least in part because there are so many existing tools researchers can leverage. Reagents that are available for evaluating the immune response [in people] work in monkeys, and so we can very carefully monitor the nonhuman primate for the development of antibodies, cytokine responses, and T-cell responses, she adds.

You always want to pick your best model for your specific question, Martinot tells The Scientist. But depending on what kind of question youre asking, or what kind of drug youre testing, you really have to choose the model that best fits your ability to answer those questions in a very accurate and reproducible way.

The World Health Organizations Research & Development Blueprint Team has been working on this since February. The team reviews progress and coordinates efforts on animal models of COVID-19 with the primary goal of advancing the development of COVID-19 therapeutics and vaccines. On September 23, some group members and a handful of other researchers published a review detailing the work thats been done to model SARS-CoV-2 infections in animalsparticularly, mice, hamsters, ferrets, and nonhuman primatesand highlighting how findings in animals correspond to disease progression in people.

The development and use of these models is not a linear process, and theyre under constant revision, says Barouch, who is part of the WHO working group. When there is human data, then that allows back validation or refinement of the model . . . so there has to be a continuous feedback from models to clinical trials and back.

In things that are so new, like SARS-CoV-2, it may well be that there is more than one useful animal model, Trimpert says. We should be open and flexible, especially in emergency situations like this.

US FDA approves TaiGens IND application for influenza drug TG-1000 – CueReport

Saturday, November 7th, 2020

TaiGen Biotechnology Company, a Taiwanese pharmaceutical company engaged in finding novel solutions to diabetes related complications, cancer, and infectious diseases, has reportedly announced that the U.S. FDA (Food and Drug Administration) has approved its IND (Investigation New Drug) application for TG-1000, a new treatment for both influenza B and A.

Along with TG-1000, TaiGen also has three more self-discovered NCEs: Furaprevir, an inhibitor of HCV protease to treat chronic hepatitis infection, TG-3000, an antagonist chemokine receptor used for chemosensitization and stem cell transplantation, and Taigexyn, a new non-fluorinated quinolone which is available in intravenous as well as oral formulations.

TaiGens novel pan influenza antiviral, TG-1000, stops viral transmission and replication using a cap-snatching mechanism. It can effectively work against influenza-B, influenza-A, Tamiflu-resistant viruses, and avian flu H7N9. The United States Patent and Trademark Office granted the first US patent for TG-1000 on 14th January 2020.

CEO and Chairman of TaiGen, Kuo-Lung Huang stated that influenza is a fatal disease with substantial unmet medical needs as well as heavy medical burden. Now, after the approval for IND by the U.S. FDA, the company is eager and ready to extend its clinical trials for TG-1000 in the United States over the coming years.

As per the Global Data, in 2019, the international market for influenza antivirals touched a valuation of $2.34 billion and is projected to hit the $5.03 billion valuation mark by the end of 2026, registering a CAGR of 11.5%.

Presently, the influenza antivirals industry only contains neuraminidase inhibitor oseltamivir and baloxavir, newly developed endonuclease inhibitor. With the recent launch of baloxavir in the industry, institutional investment analysts predict the endonuclease inhibitors' market share to rise at the cost of neuraminidase inhibitors. The companys TG-1000 is set take the complete advantage of this ongoing development.

First Man Cured of AIDS Dies From Cancer – The Keystone Newspaper

Wednesday, October 7th, 2020

By Dylan Adams News Editor

Timothy Ray Brown, the first known person to be cured of HIV, died on Sept. 29 at age 54 after battling cancer.

Timothy Ray Brown, a figurehead in the AIDS and HIV community, passed away surrounded by friends after a five-month battle with leukemia, stated Tim Hoeffgen, Browns partner.

Brown received a positive HIV diagnosis in 1995 while studying in Berlin.

In 2006, Brown was diagnosed with acute myeloid leukemia, which is a cancer that builds in the bone marrow and blood interfering with blood cell production. After bouts of infections from several rough rounds of chemotherapy, Browns leukemia came out of remission.

Due to leukemia in his bones, Brown required a stem cell transplant, a process that allows healthy stem cells to be introduced into a host to stimulate the immune system and healthy bone marrow growth. At the time, the survival rates for stem cell transplant were around fifty percent.

Doctors found a match to Browns genetic type, a donor with the CCR5 Delta 32 mutation, a protein that acts as a doorway to stop the HIV from infecting new cells. Three months after Brown stopped taking his HIV medication, doctors found he no longer had HIV in his blood.

After another round of stem cell treatment in February of 2008, Brown went through several near-death complications, almost going blind and becoming paralyzed but slowly recovering. His body was still successfully fighting off HIV.

In July 2012, the Timothy Ray Brown Foundation was created during the World AIDS Conference in Washington, DC. This foundation was built for Brown to show his support and work with medical institutions and scientists to develop a unifying cure and vaccination against HIV.

Brown would often donate large amounts of blood and tissue samples to researchers in the hope of progressing closer towards an HIV cure. According to his partner, Hoeffgen, Tims lifework was to tell his story about his HIV cure and become an ambassador of hope to those in need.

Doctors have since used Brown as a blueprint to work on a potential cure and vaccine for HIV. Most notably for the second person to ever be cured of HIV the London Patient, Adam Castillejo who went through similar stem cell transplants in 2019 before coming forward to the public.

No on Prop 14: Not the best way to support stem-cell research – Los Angeles Times

Wednesday, October 7th, 2020

In 2004, after President George W. Bush cut off all federal funding for embryonic stem-cell research on religious grounds, Californians strongly backed Proposition 71, a $3-billion bond measure to fund this kind of research, even though such funding is usually not the purview of states.

Supporters of the proposition including this editorial board believed it would allow California to stand out as a leader in this field, advance a budding avenue of research that might save lives and alleviate suffering, bolster its biotech sector and fund possible blockbuster treatments that might earn the state royalties as well. Embryonic stem cells are particularly valuable to research because they are undifferentiated, meaning they do not have a particular function, and researchers could conceivably turn them into specialized cells in order to regenerate human cells and tissue.

In the years since, Proposition 71 gave rise to a burst of scientific discovery. Two cancer treatments it helped fund, for blood and bone-marrow cancers, have been approved by the FDA, though neither of those employed embryonic stem cells and could have been funded even under Bush administration rules. It has also supported promising advances in the treatment of diabetes, bubble boy immune deficiency and vision-robbing retinitis pigmentosa, but other efforts have fallen short in clinical trials.

Moreover, the money helped build laboratories and other infrastructure that give California a head start on research and development, making the state the it place for stem-cell research. Researchers in the state moved to the head of the pack for private grants, because projects are less likely to need the time and money to create facilities before work can begin.

Now that Proposition 71 funding has practically run out, the issue is back on the November ballot with Proposition 14, which seeks nearly double the amount worth of bonds $5.5 billion to continue the juggernaut.

This time, voters should reject the measure, with the caveat that the issue could be reconsidered in a couple of years, if its proponents bring it back in better-designed and more modest form and if there are more successes in human trials and financial payback.

We have long had reservations about how the California Institute for Regenerative Medicine, established as a result of Proposition 71, was set up. Though funded publicly, it is not overseen by the governor and Legislature like other state agencies, and its governing board is too large, at 29 members. Those members generally have ties to the advocacy organizations and research institutions that have received most of the money.

The driving force behind the initiative has been Robert N. Klein II, a Bay Area lawyer and real estate investor. There is no doubting Kleins sincerity in his cause. He knows too well the suffering inflicted by intractable diseases; his son Jordan died of complications of Type I diabetes in 2016. His accomplishment in persuading the state to invest billions in a specific avenue of biomedical research has been exceptional.

However, Klein developed these initiatives largely behind closed doors with little to no public input; he has strong ideas about how things should be run on the stem-cell front and has steadfastly resisted more government oversight. Thats fine when hes investing his own money; its a fatal flaw when he is asking voters for nearly $8 billion, the estimated cost of paying off the bonds over time, according to the Legislative Analysts Office.

Kleins role and the bloated structure of CIRMs super-sized governing board have given rise to some serious ethical mishaps, including a board member who improperly intervened to try to get funding for his organization. (He is no longer on the board.) After this and several other examples of impropriety, rules were tightened. Board members must recuse themselves from votes when there is a conflict of interest, but with 29 members who all want certain projects to receive funding, there is too much potential for mutual back-scratching. Instead of repairing this problem, the new proposition would expand CIRMs board to 35 members and retain its troubling independence from oversight by the governor and Legislature, leaving it open to further conflicts of interest.

Proposition 71 hasnt yet yielded a significant financial return on investment for the state or the cures that were ballyhooed at the time. Though no one ever promised quick medical miracles, campaign ads strongly implied they were around the corner if only the funding came through. Proponents oversold the initiatives and voters cant be blamed if they view this new proposal with skepticism.

In the years since Proposition 71 passed, more resources have become available. President Obama reversed Bushs order and restored federal funding, which meant that between CIRM and the National Institutes of Health, along with private grant and investment funding, stem-cell research has been healthy, if not downright flush. That funding has stayed and even grown under President Trump, to more than $2 billion a year, with about $321 million of that in human embryonic stem-cell research. (There have, though, been recent threats to embryonic research from a group of conservative senators.)

The idea was never for California to become the long-term replacement for federal funding. It was to kick-start an industry that would then operate on its own. If that has failed to happen under Proposition 71 as promised, it shouldnt be the responsibility of California taxpayers to fix it. Thats especially true right now, at a time of yawning needs to address the cost of twin health and economic crises and the worsening effects of climate change. Private money for stem cell-work will continue to be available; its not as though research will collapse.

No doubt, the pace of responsible science is incremental and the outcomes uncertain even with the best research efforts. Yet the backers still couch the possibilities in grandiose terms. In a recent interview with the Times editorial board, Klein talked about the money that would be saved by wiping out Alzheimers disease which has so far has frustrated attempts to treat it effectively, despite many billions of dollars in research.

Embryonic stem cell research remains important, and there might be ways in which the state can contribute less grandiose funding while maximizing its investment. For example, scientific research has a well-known valley of death, where many projects cant get funding to make the transition from laboratory to human clinical trials.

Offering some matching help to get projects through that phase might attract businesses and scientists to California, while spending far less than the billions proposed in Proposition 14. Its worth noting that stem-cell work isnt the only kind of research that faces the valley of death problem; its an issue for most basic research that seeks to make the leap to human trials and that might be equally in need of state help.

Now is not the time for a huge new investment in specialized medical research. First, it makes sense to wait until after the election; if Democrats do well, there should be growing support for embryonic stem-cell research at the federal level, which is where such funding should take place. The future of Californias pandemic-battered economy and budget remains to be seen. Waiting also would give voters a chance to find out how well the states stem-cell research projects continue without state dollars, and whether some of the promising advances lead to breakthrough therapies and a return on Californias investment.

There would be an opportunity to rethink and rewrite any future proposals, which should include a far more modest ask of taxpayers as well as fixes to the structure and inflated size of the CIRM board. The institute should also be placed under the same state oversight as other agencies reporting to the governor.

If CIRM needs money for a basic operating budget over the next couple of years, that could be covered by the states general fund. The agency still needs to administer already-funded projects and could use that time to discuss a more affordable path forward. Right now, the state has other, more urgent spending priorities.

Editors note: This newspapers owner, the physician and scientist Dr. Patrick Soon-Shiong, played no role in the editorial boards deliberations on this measure.

PA Health Secretary: Sickle Cell Disease Treatment Hinges On Getting Testing – LevittownNow.com

Thursday, September 24th, 2020

Provided by the Pennsylvania Department of Health:

Secretary of Health Dr. Rachel Levine today reminded Pennsylvanians of the seriousness of sickle cell disease and the importance of getting tested for it. Sickle cell disease is the most common inherited blood disease.

We want people to get tested for sickle cell disease if they believe they could be a carrier of it, Levine said. We inherit traits from our parents like eye and hair color, but they also pass along internal traits like blood type and sickle cell conditions. It is important to be tested to confirm if you have sickle cell disease, so that treatment for the disease can be started right away to further protect yourself and your family.

Sickle cell disease is an inherited blood disease where an individuals red blood cells take a crescent or sickle shape. This change in shape can create blockages that prevent blood from reaching parts of the body. As a result, people with sickle cell complications can experience anemia, gallstones, stroke, chronic pain, organ damage and even premature death.

According to the Centers for Disease Control and Prevention (CDC), sickle cell disease affects approximately 100,000 Americans. This disease has a greater influence on African American and Hispanic populations but is also found among many other races and ethnicities.

Sickle cell disease is one of the 10 mandatory diseasesscreened for newborns. These screenings are conducted with the goal of eliminating or reducing death, disease and disability in newborn children. In addition, sickle cell disease can be diagnosed before birth to provide an early diagnosis and find treatment.

Treatment can help those with sickle cell disease live well and be healthy, but there is ultimately no cure for sickle cell disease. Treatment requires:

Finding good medical care and getting regular checkups;

Staying up to date on vaccinations and washing hands frequently to prevent infections;

Learning healthy habits;

Looking into clinical studies; and

Finding support and assistance.

Studies have shown that donated bone marrow or stem cell transplants have helped cure sickle cell disease in children with severe cases of the disease. This means that the healthy donated bone marrow or stem cell transplant replaces an individuals bone marrow that is not working properly. Bone marrow or stem cell transplants can be risky and for the donation to work the individual would need to be a close match like a brother or sister.

The Wolf administration has developed aprescribing guideline for the treatment of acute and chronic pain in patients with sickle cell diseaseto assist physicians treating patients with the disease. The guideline provides best practices to treat acute painful crises that occur with sickle cell disease patients as well as best practices for chronic pain care. The sickle cell disease guideline addresses the specific needs of that patient population. This can help prevent the misapplication of recommendations to populations that are outside the scope of other prescribing guidelines, including patients experiencing acute sickle cell crises. It is especially important to have resources specifically for the treatment of sickle cell disease patients as this patient population often experiences racial disparities and stigma.

Regenerative Therapy by Dr. Roshni Patel on Better CT – Farmington, CT – Patch.com

Thursday, September 24th, 2020

When youre in pain, its important to find effective, long-lasting solutions that can provide short recovery periods. This is what regenerative medicine offers. Over the past decade, there has been a growing field of medicine that utilizes the bodys own healing capabilities using platelet-rich plasma and mesenchymal stem cells (MSCs). This growing field is labeled as regenerative medicine. Regenerative therapies focus on healing and help regrow damaged tissue naturally. Regenerative injection therapy is used to provide relief to musculoskeletal injuries that involve damage to ligaments, tendons, cartilage, joints, and discs.

Watch video of PRP:

PRP therapy on Better CT

PRP is safeas we are using what your body naturally produces, concentrating the desired critical components and transplanting them into the affected area for effective tissue regeneration and healing. There is no risk of rejection and very minimal overall procedural risk.

FDA regulations do not allow for the cloning of stem cells or growing them in a lab. Also, stem cells derived from fat cells are not approved by the FDA as it does not allow for manipulation. This leaves us to another rich stem cell source in our body which is bone marrow. Stem cells exist in our bodies and are rudimentary cells that can differentiate into other cells.

Think of bone marrow stem cells as the mother cell that is responsible for producing new blood cells. Bone marrow contains hundreds of growth factors and is often used for severe degenerative conditions or where PRP therapy may not be sufficient to provide the growth factors needed to provide relief.

Lastly, there are many offshoot therapies that use biologics derived from placental tissue or blood cord. These biologics are sometimes marketed as Stem cells but are not stem cells and contain zero viable cells. What they contain are growth factors that can also aid when combined with PRP or Stem Cells derived from your own body.

MSCs and PRPmay be used to target a number of conditions that could benefit from their healing and regenerative qualities. Especially when considering chronic pain, alternative solutions may be necessary if it has been difficult to find relief. Along with generalized joint pain, MSCs and PRPmay be used to target:

With so many options for joint pain out there, you may be wondering what benefits choosing stem cell therapy provides. Overall, because mesenchymal stem cell therapy utilizes biologic material harvested directly from the patients body, the general benefits include minimal risk, minimal recovery time, and minimal worry:

Avoid surgery and its many complications and risks: Stem cell therapy is a minimally invasive, non-surgical procedure.

Minimal post-procedural recovery time: One of the most time-consuming factors of any injury is not always the treatment itself, but actually the recovery time. With stem cell therapy, recovery time is minimal.

No risk of rejection: Due to using biologics extracted from the patient, there is no risk of rejection.

No communicable disease transmission: As the cells originate within your own body, there is no risk of spreading disease from or to another person.

If you are suffering from joint pain, back pain, or a debilitating condition like osteoarthritis, it is important to consider all of your available options. Our elite team of professionals can determine if you are the right candidate for MSCs. If youre interested in learning more, contact us today.

About Ladiratuzumab Vedotin

Ladiratuzumab vedotin is a novel investigational ADC targeted to LIV-1. Most metastatic breast cancers express LIV-1, which also has been detected in several other cancers, including lung, head and neck, esophageal and gastric. Ladiratuzumab vedotin utilizes Seattle Genetics proprietary ADC technology and consists of a LIV-1-targeted monoclonal antibody linked to a potent microtubule-disrupting agent, monomethyl auristatin E (MMAE) by a protease-cleavable linker. This novel ADC is designed to bind to LIV-1 on cancer cells and release the cell-killing agent into target cells upon internalization. Ladiratuzumab vedotin may also cause antitumor activity through other mechanisms, including activation of an immune response by induction of immunogenic cell death.

About TUKYSA (tucatinib)

TUKYSA is an oral, small molecule tyrosine kinase inhibitor (TKI) of HER2, a protein that contributes to cancer cell growth. TUKYSA in combination with trastuzumab and capecitabine was approved by the U.S. Food and Drug Administration (FDA) in April 2020 for adult patients with advanced unresectable or metastatic HER2-positive breast cancer, including patients with brain metastases, who have received one or more prior anti-HER2-based regimens in the metastatic setting. In addition, TUKYSA received approval in Canada, Singapore, Australia and Switzerland under the Project Orbis initiative of the FDA Oncology Center of Excellence that provides a framework for concurrent submission and review of oncology products among international partners. A marketing application is under review in the European Union.

TUKYSA is being evaluated in several ongoing clinical trials and additional studies are planned. Current trials include the following:

About KEYTRUDA (pembrolizumab) Injection, 100 mg

KEYTRUDA is an anti-PD-1 therapy that works by increasing the ability of the bodys immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.

Merck has the industrys largest immuno-oncology clinical research program. There are currently more than 1,200 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient's likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.

Three-year-old bone marrow donor, Bengaluru doctors give Iraqi boy a new lease of life – The Indian Express

Tuesday, September 15th, 2020

Written by Ralph Alex Arakal | Bengaluru | Updated: September 14, 2020 8:12:24 amAhmed and his family after the successful bone marrow transplant (Express photo)

A three-year-old girl from Iraq became a lifesaver for her 18-year-old brother after she donated her bone marrow for a successful transplantation that took place in Bengaluru.

Ahmed had undergone splenectomy in his native country and was referred to Manipal Hospitals in Bengaluru since only optimal treatment is available in Iraq. According to doctors at the hospital, the teenager was also suffering from symptomatic anemia (needing frequent blood transfusions) and jaundice.

Dr Mallikarjun Kalashetty, consultant Haematology, Haemato-Oncology & Bone Marrow Transplantation at Manipal Hospitals, said Ahmed required an allogeneic bone marrow transplantation.

The best donors for such patients are the human leukocyte antigen (HLA)-matched siblings who are normal or with a minor form of haemoglobinopathy (a hereditary condition involving an abnormality in the structure of haemoglobin) or thalassaemia (a blood disorder involving lower-than-normal amounts of an oxygen-carrying protein), Dr Kalashetty explained.

However, things were not easy for the medical team at the hospital considering the age of the donor the patients three-year-old younger sister and the obvious language barrier. Transfusion experts at the hospital soon realised the process was challenging as they required the processing of 8-10 litres of blood from the donor aged three, weighing 18 kilograms, who had only a blood volume of about 1.3 litres.

Considering her age, the donor had to be sedated to elicit co-operation during apheresis (extracting blood and separating components) in multiple sittings and preserve the stem cells through cryopreservation. To counter the low volume of blood going into the apheresis machine, we filled the dead spaces with compatible RBC, and to reduce the fluid overload, we determined and monitored the volume of the fluid going into the body of the child, Dr C Shivaram, consultant transfusion medicine said.

However, the allogeneic bone marrow transplantation was successful and Ahmed has now recovered from the sickle-cell disease. He did have few complications after transplantation like mucositis, febrile neutropenia, and viral reactivation, which were successfully managed, Dr Kalashetty said.

Ahmeds quality of life has improved significantly and his parents are overjoyed to see their son doing so well after suffering from the illness for several years. The satisfaction of seeing the joy on the faces of the patient and his family is unmatched, he said.

‘Mini organs’ offer treatment hope for children with intestinal failure study – The Northern Farmer

Friday, September 11th, 2020

Mini organs grown using stem cells from a patients tissue could offer hope for children with intestinal failure, a study suggests.

Scientists at the Francis Crick Institute, Great Ormond Street Hospital (GOSH) and UCL Great Ormond Street Institute of Child Health (ICH) have grown human intestinal grafts using stem cells from patient tissue.

The team hope the findings could one day lead to personalised transplants for children with intestinal failure.

Dr Vivian Li, senior author and group leader of the Stem Cell and Cancer Biology Laboratory at the Crick, said: Its urgent that we find new ways to care for children without a working intestine because, as they grow older, complications from parental nutrition can arise.

Weve set out a process to grow one layer of intestine in the laboratory, moving us a step closer to being able to offer these patients a form of regenerative medicine, which uses materials created from their own tissue.

This would reduce some of the risks that transplant patients face, such as their immune system attacking the transplant.

Children with intestinal failure cannot absorb the nutrients essential for their overall health and development, researchers said.

While they can be fed intravenously, via a process called parenteral nutrition, this is associated with severe complications such as line infections and liver failure, they added.

If complications arise, or in severe cases the children need a transplant, researchers said there is a shortage of suitable donor organs and problems can arise after surgery such as the body rejecting the transplant.

The proof-of-concept study, published in Nature Medicine on Monday, showed how intestinal stem cells and small intestinal or colonic tissue taken from patients can be used to grow the inner layer of small intestine in the laboratory with the capacity to digest and absorb peptides and digest sucrose in food.

The researchers took small biopsies of intestine from 12 children who either had intestinal failure or were at risk of developing the condition.

In the lab they then stimulated the biopsy cells to grow into mini-guts, also known as intestinal organoids, generating over 10 million intestinal stem cells from each patient over the course of four weeks.

The researchers also collected small intestine and colon tissue that would have been discarded from other children undergoing essential surgery to remove parts of their gut.

Using laboratory techniques cells were removed from these tissues leaving behind a skeleton structure which formed scaffolds.

The researchers placed the mini-guts onto these scaffolds where they grew on this structure to form a living graft.

Due to specific culture conditions, the stem cells changed into many of the different types of cells that exist in the small intestine and the grafts were able to digest and absorb peptides, the building blocks of proteins, as well as digest sucrose into glucose sugars.

The authors said research was the first step in efforts to engineer all the layers of the intestine for transplantation in the hope that laboratory-grown organs could offer a safe and longer-lasting alternative to traditional donor transplants.

Senior author Professor Paolo De Coppi, consultant paediatric surgeon at GOSH, said the research was an important step forward in regenerative medicine.

He added: Although this research is in the lab right now, were concentrating on making this a realistic and safe treatment option.

Whats significant here is weve shown that scaffolds can be created using tissue from the colon, not only tissue from the small intestine.

Its an important step forward in regenerative medicine and were optimistic about what this means for patients, but more research lies ahead before we can safely and effectively translate this approach to treatment.

As well as proving that biopsies taken from children could be used to grow functioning intestinal grafts, the researchers said that the grafts can survive and mature when transplanted into mice.

Researchers said the next step was to start growing the other layers of the intestine such as muscle and blood vessels.

What Is Covid-19 Doing to Our Hearts? – The New Republic

Friday, September 11th, 2020

Brady Feeney hadnt even taken any classes at Indiana University when he fell ill with Covid-19. Three weeks after he moved to Bloomington, the incoming freshman was in the emergency room, struggling to breathe. Before his illness, Feeney had been a perfectly healthy teenager, with no preexisting conditions. In high school, he was a three-time all-state football player and won two state titles in Missouri. But after two weeks of hell fighting the virus, his mother said, his bloodwork indicated possible heart problems.

When SARS-CoV-2 first struck the United States, the medical community had two working assumptions: First, this was primarily a respiratory disease, and second, it seemed to hit older people much harder than younger people, with eight out of 10 confirmed Covid-19 deaths in the U.S. happening in adults 65 or older. But now, new research is challenging both of these assumptions.

Growing evidence suggests that SARS-CoV-2 doesnt only infect the lungs. It also affects the brain, kidneys, and heart. At first, doctors and researchers wondered if these issues beyond the lungs came just from the stress of having Covid-19 and being on a ventilator or life support. But increasingly, research indicates that the virus may be attacking other organs in the body directlyand this may be more common than previously thought, even among those who arent sick enough to be hospitalized. Some have suggested that Covid-19 is actually a blood vessel disease; the lungs are merely the way the virus enters the body, but from there it gets into the bloodstream and takes up residence in major organs, leaving patients with complex, long-lasting symptoms. Moreover, experts now believe, healthy young people can get mild cases of the coronaviruseven not knowing they were sickthat could leave them with lasting cardiovascular damage. Even those who seem to have recovered from the deadly respiratory illness are not free of its complications.

Heart failure could be the next chapter of the coronavirus illness, Dr. Gregg C. Fonarow, interim chief of UCLAs Division of Cardiology, recently argued in a co-authored editorial in the journal JAMA Cardiology. Even if in younger adults Covid-19 may not be fatal, there still may be important health consequences, he told me.

Myocarditis, or inflammation of the heart, is usually a rare condition that can occur with viral infections, including the flu. But from the start of the pandemic, doctors were seeing heart inflammation among patients hospitalized with serious cases of Covid-19, Fonarow said: Early research showed that 20 to 30 percent of those hospitalized had heart issues. Left untreated, myocarditis can damage the heart and lead to heart attacks and arrhythmias, among other complications.

Tweet Chat Recap: Evaluating Treatment Approaches for Relapsed/Refractory DLBCL – Targeted Oncology

Friday, September 11th, 2020

Targeted Oncology was joined by Kami J. Maddocks, MD, associate professor of clinical internal medicine, Division of Hematology, The Ohio State University Comprehensive Cancer CenterJames, for the discussion of a 76-year-old man with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) in a recent tweet chat. In this case scenario, the patient presented with stage IV high-risk disease and received R-CHOP (Rituximab [Rituxan], cyclophosphamide, doxorubicin, vincristine, prednisone), and radiotherapy.

Although the treatment appeared well-tolerated, the patient presented with similar symptoms as at diagnosis after completing 6 cycles with complete response to the therapy. According to the work-up, the patient is ineligible for transplant.

The patient was ineligible for stem cell transplantation (SCT), which Maddocks speculates may be due to the patients age, although other considerations could include comorbidities or intolerance to R-CHOP. Eligibility is the first thing she considers for her patients as it is currently the standard of care and the only curative approach for patients to receive salvage chemotherapy followed by consolidation with autologous SCT.

Maddocks told Targeted Oncology, In some patient cases, [the reason for ineligibility] is age even though there's no specific age cutoff, but we know that it's harder on the marrow as patients get older to collect stem cells and get that aggressive salvage chemotherapy. Patient comorbidities [can also impact eligibility], so heart conditions, lung conditions, renal insufficiency can be a problem. Performance status and then lastly, just if the patient had trouble getting to their initial chemotherapy with R-CHOP or had a lot of complications, then it's probably going to be harder for them to tolerate even more aggressive or intensive therapy.

In a twitter poll ahead of the chat, Targeted Oncology asked what the next best line of therapy for this patient might be, with 4 potential different treatment options. The option that drew the most attention, however, was the recently approved regimen of tafasitamab (Monjuvi) and lenalidomide (Revlimid).

Maddocks tweeted, All these options are potential therapeutic choices for this patient, but the combination of tafasitamab/lenalidomide is the only option approved in this setting. The treatment has a promising ORR [overall response rate], and CR [complete response], and the remissions for patients who respond are durable!

During the tweet chat, Maddocks reviewed each of the different treatment options in the poll, and why she selected this combination regimen as the next best line of therapy for this particular patient. Following the chat, she spoke with Targeted Oncology to share further insights on each of these therapeutic approaches and the importance of the FDAs approval of tafasitamab plus lenalidomide in this setting.

The combination of tafasitamab plus lenalidomide held the majority vote, which Maddocks agreed would be the next best line of therapy for this patient.

For patients who are not candidates or considered eligible for a salvage chemotherapy followed by autologous SCT, the tafasitamab/lenalidomide combination was recently approved in the setting of first relapse, and it's the only approved therapy in this setting, Maddocks said. Historically, we would give some sort of palliative chemotherapy approach if patients were candidates and interested in pursuing therapy, or consideration of clinical trial, but this is the only therapy approved in this setting.

The approval of tafasitamab in combination with lenalidomide includes an indication for patients who are not eligible for autologous SCT, as describes the patient in our case. This regimen was approved on the basis of the phase 2 L-MIND (NCT02399085) clinical trial, which explored this use of this regimen in 81 patients with relapsed/refractory DLBCL. Two-year follow-up demonstrated an ORR of 58.5%, which included CRs in 41.3% of patients and partial responses (PRs) in 17.5% of patients. In addition, 15.0% achieved stable disease, and the median duration of response was 34.6 months (95% CI, 26.1-34.6).1

I think this patient case is the perfect example of where this can fit into the treatment landscape, Maddocks explained. For patients who first relapse from the standard R-CHOP therapy, the toxicities were generally manageable, and with the response rate, this is a great option for patients at first relapse who are not going to be candidates for a transplant. I think maybe patients who go on to get palliative chemotherapy or maybe patients who get treatment with plans to go to transplant but just don't tolerate it and dont look like they're going to [undergo] aggressive therapy, this may be an option for those patients too, understanding that there is some role for CAR T in a set of those patients.

This study, which was presented during the 25th Congress of the European Hematology Association (EHA), demonstrated that the majority of toxicities were hematologic, and most were reversible. The most common grade 3 hematologic treatment-emergent adverse events (TEAEs) were neutropenia in 49.4% of patients, thrombocytopenia in 17.3%, and febrile neutropenia in 13.2%.1

These were able to be managed by holding the dose growth factor, and there was a population of patients who had to be dose-reduced on the lenalidomide. The starting dose was 25 mg, so the majority were able to maintain 20 mg if they were dose-reduced, although a few had to be reduced more than once, Maddocks said. The most common grade 3/4 or serious AEs were infection, probably not surprisingly, and overall, that's probably similar to what you see with other options in this setting. There was a small number of infusion reactions, but these were all grade 1 in the trial and were easily managed.

Non-hematologic TEAEs of grade 3 included pneumonia in 8.6% of patients and hypokalemia in 6.2%. Serious AEs reported included pneumonia in 8.6%, febrile neutropenia in 6.2%, and pulmonary embolism in 3.7%, as well as bronchitis, lower respiratory tract infection, atrial fibrillation, and congestive cardiac failure in 2.5% each.1

Given the safety profile of this combination of tafasitamab plus lenalidomide, this regimen is particularly suitable for a large proportion of patients with DLBCL, Gilles Salles, MD, PhD, lead author of L-MIND, toldTargeted Oncology. We do know that the median age of occurrence of DLBCL is in the late 60s, and there are many, many patients that are over 70 and that are not usually transplant eligible. Clearly this is a great opportunity for patients to receive this non-cytotoxic regimen.

Although this regimen is an exciting opportunity for patients with DLBCL and relapsed/refractory disease, 1 challenge that needs to be addressed is the potential use of tafasitamab plus lenalidomide in sequence with CAR T-cell therapy. There is very little experience, if any, of patients receiving the combination regimen after receiving CAR T-cell therapy. The combination and CAR T cells both target the same antigen, CD19, which can be problematic. As its known that some patients will lose CD19 expression on CAR T-cell therapy, the regimen may no longer be an effective treatment option.

For those patients that had failed CAR T-cell therapy, substantial proportions, about 30% of them, may have lost CD19 expression and then may not be eligible anymore for this regimen. There is, however, a substantial proportion of patients that retains CD19 and in whom tafasitamab/lenalidomide can be used as a treatment option, Salles commented.

A large proportion of patients will maintain CD19 expression following CAR T-cell therapy, so tafasitamab plus lenalidomide may still be effective in a percentage of patients.

Its hard to say because we dont have a lot of data, but we do know there are other CD19-directed therapies outside of CAR T cell development, Maddocks told Targeted Oncology. I think in the next few years, were going to see patients treated both pre- and post-CAR T with other CD19-directed therapies, and well have more information on this.

The combination of polatuzumab vedotin (Polivy) plus bendamustine (Bendeka) and rituximab (BR) was approved by the FDA as treatment of patients with relapsed/refractory DLBCL after 2 prior lines of therapy in June 2019 based on the findings from the phase 1b/2 GO29365 (NCT02257567) clinical trial. Although this option is also not FDA-approved for the treatment of patients after first relapse, Maddocks noted that this was the only treatment evaluated in a randomized trial. The study had included patients who were ineligible for transplant.

Significant improvements were observed with polatuzumab vedotin plus BR compared with BR alone in an international, multicenter, open-label study, particularly in regard to the ORR, CRs, progression-free survival (PFS), and overall survival (OS). CRs were observed in 40.0% of the patients with the combination versus 17.5% with BR alone. Survival rates favored the combination as well, with a median PFS of 9.5 months with the combination versus 3.7 months with BR alone (HR, 0.36; 95% CI, 0.21-0.63; P <.001) and a median OS of 12.4 months versus 4.7 months (HR, 0.42; 95% CI, 0.24-0.75; P =.002), respectively.2

The addition of polatuzumab did increase toxicity from the standpoint of cytopenias, but that didn't really translate to increased serious infections. It did add neuropathy as a side effect, but most of that was reversible, so I think this was a regimen that, by the addition of polatuzumab, was something that you could offer patients that did give them somewhat of a better overall response and was more durable than just giving them a palliative chemotherapy alone, Maddocks added. This is also a regimen that's been used in patients who were not able to achieve a remission to bridge them to CAR T or in some patients after CAR T, and so I can understand why this was definitely one of the more favorable choices.

In the study, grade 3/4 neutropenia was observed more frequently in the combination arm (42.6%) compared with the BR alone arm (33.3%), but the occurrence of grade 3/4 infections was comparable between the 2 groups (23.1% vs. 20.5%, respectively). In addition, the study authors noted that although many of the fatal AEs occurred after disease progression, 11 patients in the BR arm experienced fatal AEs compared with 9 in the combination arm, infection being the most common, which was the cause in 4 patients in each arm.2

Although the regimen appeared tolerable in this setting, Maddocks tweeted, it is more attractive than chemotherapy alone and understandable why it was chosen [as the second-best option in the Twitter poll].

Among the treatment options considered in our twitter poll ahead of the tweet chat, selinexor (Xpovio) only caught the attention of 16.7% of voters, similar to CAR T-cell therapy. However, both of these options are currently only approved in patients who have received at least 2 prior lines of therapy, which this case did not.

In regard to selinexor in particular, Maddocks tweeted, Looking at the single arm phase 2 data, it also has the lowest overall response rates of all the options listed with an ORR of 28%.

Selinexor received its approval from the FDA in June 2020, which is indicated for the treatment of adult patients with relapsed/refractory DLBCL, not otherwise specified, who have received at least 2 prior systemic therapies. This is the only oral single-agent therapy approved in this setting, and it is also the only nuclear export inhibitor approved by the FDA for use in hematologic malignancies.

The agent was approved on the basis of the phase 2b SADAL clinical trial, which demonstrated an ORR of 29% with 13% CRs and 16% PRs. The responses achieved in the study were durable, which led to a median duration of response of 9.2 months in the overall population (95% CI, 4.8-23.0) and 13.5 months in those who had achieved a CR (95% CI, 9.3-23.0).3

The most common treatment-related AEs were cytopenias and gastrointestinal/constitutional symptoms, which were generally reversible and manageable with dose modifications and/or standard supportive care approaches. The most common on-hematologic AEs, which were mostly grade 1/2, were nausea (52.8%), fatigue (37.8%), and anorexia (34.6%). The most common grade 3/4 AEs included thrombocytopenia (39.4%), neutropenia (20.5%), and anemia (13.4%). No treatment-related grade 5 AEs were observed.

CAR T-cell therapy, on the other hand, offers a unique option to this patient case even though it is still only approved in patients who have progressed or relapsed after 2 prior therapies or SCT. The TRANSCEND-PILOT-017006 (NCT03483103) study is evaluating the potential for CAR T-cell therapy lisocabtagene maraleucel (liso-cel) as treatment of patients with relapsed/refractory aggressive B-cell non-Hodgkin lymphoma who have received at least 1 prior therapy and are ineligible for SCT. While this does appear promising for introducing CAR T-cell therapy earlier on for patients with DLBCL, the treatment is not available off trial and is not a standard approach.

Maddocks told Targeted Oncology, It's very clear who's eligible for autologous transplant by age and comorbidities, but with CAR T, it's not so clear all the time who is going to be a candidate. There's not as great of data or information on who is going to be a candidate for that or not. Probably more patients are going to be a candidate for transplant, but there is still going to be patients that are comorbidities that they're not going to be a candidate for CAR T cells, and while they're approved in this setting and they can be very effective, there's also logistical issues, including that right now there's only certain centers, most often transplant centers, that are able to administer CAR T cells, so the patient has to have access to a center, they have to be able to get through the time that their leukapheresis cells are sent out and then sent back, and there's still barriers to cost and insurance in some patients, too.

This particular patient case does represent a challenge, Maddocks said. Historically, this is not a patient that's going to be a candidate for an autologous SCT, and that's going to be the only curative approach. CAR T is not approved in this setting, which is the other curative approach we know outside of patients who are unable to get to autologous STC, or at least appears to be likely curative for a percentage of patients.

Overall, CAR T-cell therapy is not a viable treatment option for the patient depicted in our tweet chat discussion, although it can still offer curative opportunities to a select group of patients with DLBCL who are ineligible for transplant.

In conclusion, tafasitamab plus lenalidomide helps fulfill the unmet need of patients who are in first relapse but are ineligible for transplant, which is the only curative option for patients with relapsed/refractory DLBCL. Although CAR T cells appear hopeful in this space, more research needs to be done to further determine their role in the treatment paradigm.

When you look at relapsed DLBCL, in general, and have these options, it's exciting for our patients to be able to have these. All of these have come up in the last 1 to 2 years, CAR T being a little bit longer than the other 3 regimens, but they all have offered patients tolerable therapy in the setting of previously not having these options.

Roche receives FDA clearance for BK virus quantitative test on cobas 6800/8800 Systems to support better care for transplant patients – Yahoo Finance

Friday, September 11th, 2020

Basel, 8 September 2020 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced U.S. Food and Drug Administration (FDA) 510k clearance for the cobas BKV Test on the cobas 6800 and 8800 Systems. The test was previously granted FDA Breakthrough Device designation demonstrating the improved treatment or diagnosis of life-threatening diseases or conditions for transplant patients. The test provides standardised, high-quality results that can help healthcare professionals better assess the risk of complications caused by the BK virus in transplant patients and identify effective treatment options.

BK virus (BKV) is a member of the polyomavirus family that can cause severe transplant-associated complications. Infection can occur without symptoms and happen early in life. After primary infection, the virus can remain inactive, only to possibly reactivate in immunocompromised individuals such as transplant recipients.

Our diagnostic tests can help clinicians greatly improve patient treatment plans and make quick adjustments for personalised healthcare, said Thomas Schinecker, CEO Roche Diagnostics. This FDA clearance allows Roche to offer healthcare professionals a transplant testing portfolio that includes Cytomegalovirus, Epstein-Barr virus and BK virus so they can simultaneously monitor and improve care for transplant patients who are at risk for these common infections or viral reactivations which can cause further illness or death.

The cobas BKV Test is a polymerase chain reaction (PCR) viral load test that runs on the fully automated and widely available cobas 6800 and cobas 8800 Systems. Along with the previously approved cobas EBV and CMV Tests, the cobas BKV Test has been calibrated to the World Health Organization (WHO) International Standard. This means that test results are reported in international units, making it possible for laboratories anywhere in the U.S. to obtain comparable results when measuring levels of BKV DNA.

About the cobas BKV TestThe cobas BKV Test was previously granted Breakthrough Device Designation by the FDA, together with the cobas EBV Test.

The cobas BKV Test is a real-time polymerase chain reaction (PCR) test with dual-target technology that provides quantitative accuracy and guards against the risk of sequence variations that may be present in the BK virus. The cobas BKV Test has robust coverage with a limit of detection of 21.5 IU/mL and an expanded linear range from 21.5 IU/mL to 1E+08 IU/mL in EDTA plasma.

The test offers an alternative to lab-developed tests (LDTs) or Analyte Specific Reagent (ASR) combinations, potentially minimising variability and complexity in testing, reducing workload and alleviating risk for laboratories. The test supports the goal of result standardisation across institutions by providing reproducible, high-quality results for clinical decision-making.

The fully automated cobas BKV Test and the cobas CMV and cobas EBV Tests can run on the cobas 6800/8800 Systems simultaneously, providing absolute automation with proven performance and flexibility, leading to time savings and increased efficiency.

About BK polyomavirus BK polyomavirus (BKV) is a member of the polyomavirus family that can cause transplant-associated complications including nephropathy in kidney transplantation and hemorrhagic cystitis in hematopoietic stem cell transplantation. Infection can occur early in life, often with no symptoms. After primary infection, the virus can remain inactive throughout life, only to possibly reactivate in immunocompromised individuals, such as patients who receive solid-organ transplants. For kidney transplant patients, BKV infection is considered the most common viral complication, causing polyomavirus nephropathy (PVN) in up to 10 percent of kidney transplant recipients, and about 50 percent of PVN-affected patients will experience transplant graft failure.1 BKV is also associated with hemorrhagic cystitis after allogeneic hematopoietic stem cell transplantation.2

About the cobas 6800/8800 SystemsWhen every moment matters, the fully automated cobas 6800/8800 Systems offer the fastest time to results with the highest throughput and the longest walk-away time available among automated molecular platforms.

Coronavirus, Charity, and the Trolley Problem – Crooked

Friday, September 11th, 2020

I signed up to be a bone marrow donor in 2016, after an anonymous strangers marrow saved my father. It started out easy enough: The registry mailed me a kit to swab my cheeks, I mailed it back, and then I heard nothing for years. This wasnt unusual. Marrow transplantation requires finding complex and rare genetic matches; according to Be The Match, only about one out of every 430 people who sign up will ever go on to donate. I expected it would be a while before I got to pay my dads transplant forward. It did not occur to me that my opportunity might arise at the height of a global coronavirus pandemic.

The coronavirus created a tangle of moral dilemmas that most Americans never expected to face. At the extremes, weve resolved these dilemmas easily. Weve designated whole categories of labormostly underpaid, perennially underappreciatedessential because we accept that even with a plague lurking, people must eat and medicate and have working showers in which to cry. On the opposite end of the spectrum, weve trained our online shaming apparatus on the most reckless and selfish offendersthe wealthy New Yorkers who fled to the Hamptons, the house parties posted to Instagram with weak defensive captions (we only took our masks off for the body shots).

The longer we live in the shadow of an uncontained virus, the more agonizing the in-between dilemmas become. How long should people be expected to remain isolated from their loved ones? Is there a point at which the negative effects of physical distancing begin to outweigh the toll of the disease itself? On the one hand, we should do everything in our power to protect the most vulnerable in our communities. On the other hand, what should we tell the vulnerable seniors who feel they dont have endless spare months to let pass without embracing their grandchildren? Are our individual mitigation responsibilities lessened by the fact that we all made sacrifices to buy an incompetent president time to get this under control, and he squandered it? Are we that much more obligated to pick up the slack?

In some sort of sick philosophical joke, the moral waters get even murkier when you throw altruism into the mix. For all of the guidance reminding us of the impact of our selfish choices on strangersyou might not kill your own grandmother by going to that dive bar, but think of the bartenders roommates grandmothermoral experts have had far less to say about the boundaries around charitable acts. How should we think about helping strangers when doing so requires a dangerous level of social interaction? How should we measure the suffering of the people we want to help against the harm we risk causing to unseen others in the process? That quandary leads to another awful question that most people should never have to confront: When does human life become too risky to save?

Be The Match first notified me that it had identified me as a potential match in June, when coronavirus cases in Los Angeles, where I live, had just begun to spike. By the time I was confirmed as the patients best match and asked to proceed with a donation several weeks later, the city had become a full-blown hotspot. The idea of navigating the whole process in plague conditions made me nervous, but underneath the anxiety was a distinct whiff of relief. Like a lot of people, Id spent the last few months in a horrified daze, helpless to do anything but stay home, donate money, and cyberbully the mayor. Here, finally, was a task that felt equal to the urgency of the moment. Here was somethingsomeonereal. I just wasnt allowed to know who.

Be The Match will put donor and recipient in contact one year after the transplant, if both have consented; until then, everything is completely anonymous. I was told that my recipient was a man in the United States, along with his age (surprisingly young), and diagnosis (a type of blood cancer). Because matches are typically found within shared ancestries, I assume that he is, like me, an Ashkenazi Jew, and because he needed a bone marrow transplant, his situation must have been dire.

Fortunately, helping people like him has become simpler. When most people think of donating for a bone marrow transplant, they imagine general anesthesia; a very big needle; a painful recovery. This is one of the two ways to donate, but its grown much less common. Ninety percent of donors (including me) are instead asked to donate peripheral blood stem cells (PBSC), through a process called apheresis. While a donor is awake and watching Party Down, their blood flows through a tube attached to one arm, gets spun around in a centrifuge that separates out the extra blood-forming stem cells, and is returned through a tube into the other arm. This can take several hours, but its painless, and neednt even happen at a hospital. Usually.

(Sarah Lazarus)

On August 13, two nurses met me at the San Bernardino blood bank where I was scheduled to donate later that month. We were all there for an assessment, to make sure my arm veins could handle the apheresis needles. It was a weird little ritual. The two women bent on either side of me, intently tapping along my upturned arms in total silence as if waiting for something to tap back. They then switched sides, tapped the opposite arm, and issued their verdict: Too small. I would need to donate through a central line placed in one of my larger veins, and that could only happen at a hospital. I would probably be sent to a medical center two hours south in La Jolla, they told me.

This was a complication, but not necessarily a big deal. Be The Match footed the bill for all of my donation-related expenses, including the fancy car service that seemed safer, COVID-wise, than using Lyft. (I am a genius who moved to Los Angeles without a drivers license. A worse essay for another time.) Donating at the La Jolla hospital would mean a longer commute, maybe even one night in a hotel, but that was about it.

Later that morning I was waiting for my next appointment at an urgent care center when Heather, my donor coordinator, called to tell me that La Jolla didnt have an opening on the right day. Neither did the next-closest option, she told me as I paced around the parking lot, and the patients team couldnt shift his treatment schedule.

So my question for you is, would you feel comfortable flying to Boise, Idaho?

I went back inside to the busy waiting room and reclaimed my seat. Across the room, a man in a UPS uniform freed his nose to rest obscenely on top of his mask. I hunched over my phone and googled, Boise coronavirus. My phone informed me that it was dying. The UPS man coughed. On a TV in the corner, the president admitted he was sabotaging the post office to steal the election. I googled, airports coronavirus. At last, a nurse called me back and started checking my vitals.

Your heart rate is really elevated, she said, frowning at the reading. Any idea why?

As of this writing, Be The Matchs COVID-19 FAQ page was last updated on April 6. Heres part of the section on air travel:

Q: Are there alternatives to donors traveling for donation?A: Possibly. If you feel uncomfortable traveling, we respect your decision. However, it is extremely important that you tell us right away so we can look for alternatives. Donation is time-sensitive, and any delay can have a negative impact on the recipients wellbeing. It may be possible to arrange for donation to occur somewhere within driving distance.

There was an alternative to Boise, it turned out, if I felt uncomfortable. I could donate at the La Jolla hospital a day later than originally planned. My cells would be cryogenically frozen and given to the patient a week or two later, instead of immediately. Heather told me that the patients team preferred me to stick with the original date, that a delayed transplant would be riskier for him, but, for confidentiality reasons, they couldnt tell me how much riskier.

We dont want you to feel pressured, Heather emphasized. You should only agree to travel if you feel comfortable.

Did I feel comfortable? It depended on the circumstances, which I wasnt allowed to know. The window of risks were willing to take expands as the stakes get higher; anyone who showed up to a Black Lives Matter protest this summer or signed up to be a poll worker this fall can attest to that. I wouldnt feel at all comfortable flying for the heck of it, but I would certainly do it to save a life. This fell somewhere on the vast spectrum in between, but I had no idea where.

How do you make a call about your personal risk tolerance when its also a choice about the course of a strangers cancer treatment? If the pandemic had taught us all a valuable lesson about the interconnectedness of our fates, I was now being beaten over the head with it. Stuck without enough facts to make an informed decision, I thought about my dads old hospital room in Baltimore, the airlock separating his ward from the rest of the building because any mundane microbe could kill the patients on the other side. I imagined a somber-looking doctor walking through those doors to give my vulnerable recipient the news.

Im afraid theres been a change of plans, he would say, removing his glasses. It seems your donor is a pussy-ass bitch.

I called Heather back and told her to arrange my donation in Boise.

In most respects, my pre-donation medical screening was extremely, almost ludicrously thorough. I submitted vials and vials of blood to check for a host of diseases and disorders. I peed in a cup to make sure I wasnt pregnant. I had more blood drawn, to make sure I really wasnt pregnant. After the second pregnancy test confirmed the results of the first pregnancy test, I got the following email from Heather:

The result of your repeat pregnancy test on 8/13 was negative, but we are still required to complete our pregnancy assessment with you today. The assessment consists of a single question Is there any chance you could be pregnant? Please respond via email when convenient.

I have not touched another person in five months, I wrote back.

Thank you for completing the pregnancy assessment, Heather replied.

In one respect, my pre-donation medical screening seemed oddly lax. I wasnt tested for coronavirus until the day before my flight, and only then because I panicked.

(Sarah Lazarus)

The PBSC donation process begins in earnest a few days before the stem cells are actually collected, with five rounds of filgrastim injections. Its a drug normally given to cancer patients to bring up low white-blood cell counts after chemo or radiation. In my case, it would send my healthy bone marrow into overdrive, to produce enough cells for the donation. The injections have a few side effects: bone pain, fatigue, headaches, nausea. Essentially, filgrastim makes you feel like you have the flua particularly special feeling in the year of our lord 2020. My side effects were mild and I knew to expect them, and I was managing them fine until an extra one showed up.

The night after receiving my second round of shots, I went for a walk around my neighborhood. It was a hot night, and I was tired and achy from the medication; this was not a fast walk. And yet within a few blocks I noticed that my breathing was quick and shallow, and my heart was pounding as if Id just run a sprint. When I tried to take a deep breath, it felt like there was an elastic band cinched around my chest.

Shortness of breath was not on my list of filgrastim side effects. Neither were the heart palpitations, which continued long after I went home and collapsed on my bed.

I put an empty Gatorade bottle on my stomach and watched it pulse up and down as I considered how fucked I was. I had assumed my fatigue and body aches were side effects; what if those were symptoms, too? I mentally tallied up my appointments from over the past week. I had been to five different medical facilities, been a passenger in three different cars. Of course I had caught it. How stupid to think I wouldnt catch it.

The timing was a nightmare. At some point while I was receiving the filgrastim injections, the patient began a course of high-dose chemo to kill off his own blood-forming stem cells in preparation for the transplant. If I had to back out of donating after that treatment began, the patient would die quickly.

For a few desperate minutes, I thought about keeping these symptoms to myself. I didnt have a fever. As long as I didnt develop one, maybe I could get to Boise and finish the donation leaving no one the wiser. What was the moral math, I wondered, of proceeding with travel plans that might seed multiple new outbreaks (but also might not) and lead to numerous deaths (but maybe none), knowing that if I didnt, one person would certainly die? Had anyone solved that particular trolley problem? My heart palpitations got worse. This was insane. I texted Heather everything and asked if she could arrange for a rapid coronavirus test the next day.

It was nearly 11 p.m. by this point, later in Heathers time zone. She made sure my shortness of breath wasnt an emergency, then said shed see how I was feeling in the morning to assess whether a test was necessary.

I went to bed and thought about what they would tell the patient. Would his doctors be allowed to explain why I couldnt donate? Would he think I had just bailed? Would he and his family hate me? What did it say about my motivations that I was fixated on this? Probably nothing good. I drifted off into a stress dream, and then it was dawn.

My breathing was still labored in the morning, and now, compounding my dread, I had a definite tickle in my throat that verged on a cough. Heather and the medical team decided this did indeed warrant a coronavirus test, and went about setting one up. In the meantime, Heather told me, I should proceed with my third day of filgrastim.

When my home nurse Maria arrived at 8 a.m. to do the honors, I stopped her outside to inform her that I might be a vector of death. She was unimpressed. (Ok, sweetie. Can I come in and wash my hands?) Soon afterwards, Heather called to let me know she had found a doctors office that would send someone to test me at my apartment, and deliver results within 24 hoursjust fast enough that I could still make my flight if I tested negative. Be The Match picked up the tab for this, too, but the receipt came to my email. The cost of a rapid PCR test, antibody test, and home visit came out to a cool $900.

The unaffordable testing nurse arrived an hour later cloaked in full PPE. She coached me on how to swab my own mouth and throat for the diagnostic test, then we made small talk while waiting for the little white antibody tray, which looked for all the world like yet another pregnancy test, to reveal either one or two lines. She had been doing these home visits for two weeks, she told me, and none of her patients had yet tested positive for an infection. For no good reason at all, this made me feel better. The antibody test came up negative. The nurse wished me luck with my other results and headed off to her next appointment, leaving me alone with my wonderful thoughts.

I had nothing to do for the rest of the day but wait. By late afternoon my throat felt better, and my breathing had become less conspicuous. At one point I started to pack a bag, wondered if I was jinxing it, and unpacked the bag. At 10 p.m., less than 12 hours after my throat swab, the results arrived in my inbox. NOT DETECTED. I texted Heather a screenshot and lay down on the floor, awash with relief.

(Sarah Lazarus)

The travel and donation themselves were mercifully uneventful. My parents, who were very pleased that I was donating and terrified that I was flying, had shipped me a steady stream of hand sanitizer, KN95 masks, surgical masks, disinfectant wipes, face shields, safety glasses, and gloves. I wore only some of this to the airport, unless you are my parents, in which case I wore all of it. In any event, I felt protected. My terminal at LAX was deserted, and Heather had booked me a first class seat on Delta, which limits capacity to 50 percent. After barely leaving my immediate neighborhood for half a year, the feeling of takeoff, even for a two-day trip to Boise, was sensational.

The next day I arrived at the hospital at 7:15 a.m. By 8:30 Id had a central line inserted above my collarbone, in a painless 15-minute procedure under local anesthesia. The song We Are Young was playing, and the doctors threading a tube into my neck were chatting quietly about a patient whod given them trouble over the weekend. (Im just saying, if youre cussing people out and trying to beat me up, you probably didnt have too bad of a stroke.) Ive had much less pleasant mornings.

By 9:30 I was in bed and hooked up to the apheresis machine, where I would remain for the next seven hours. At one point my calcium levels dropped too low and I threw up; this was the excitement peak of the day. I spent the rest of the time comfortably reading or watching Netflix, keeping an eye on the stem cells slowly collecting in the bag above my head, and carefully avoiding any RNC coverage that might cause the nausea to recur. At around 4:30 I was loosed from the machine, and after waiting a couple more hours while the lab made sure I had forked over enough cells, the nurse removed my central line and I was officially done.

I was exhausted that evening, but the next day felt well enough to go for a walk along the Boise River, where I took 50 terrible photos of a great blue heron. My shortness of breath, whatever it had been, was gone. The day after that I was just a little more fatigued than usual, and by day three I was back to my 2020-adjusted tiredness baseline.

Coronavirus complications aside, the actual donation process was remarkably easy; shockingly easy, when you consider the scale of what it means for the recipient. It was a time commitment for a few weeksIm lucky to have employers who were happy to give me the necessary leaveand involved some mild discomfort, but as a baby about both pain and scheduling, I would not hesitate to do this again.

I also came away with a clearer sense of how to approach the kind of altruistic acts that standard social-distancing guidelines say we shouldnt engage in. The people and organizations that facilitate charity, particularly sensitive medical charity, have existing support systems that theyve retrofitted to help mitigate the extra risks. Those systems may be imperfect and require some self-advocacy, but when combined with ones own diligence and added layers of protection (and, if one is lucky, a concerned Jewish mother), its possible to get help to the people who need it with risk levels not much higher than we tolerate in normal times. There is a way to be selfless without being self-sacrificing, or worse, becoming an inadvertent menace.

Even so, pandemic experiences like this one wont be universally feasible. One might live with immunosuppressed family members or roommates, or have care-taking responsibilities, or lack the spare emotional bandwidth, or have any number of circumstances more complex than my own. And thats finethere will still be people in need of a lifeline on the other side of this crisis, and that lifeline will be no less appreciated.

I asked my dad, Mitchell Lazarus, what he thought potential donors should know about the recipient experience. He sent me this:

The diagnosis is, literally, a death sentence: you will soon die. Word of a matching donor who has agreed to participate is a reprieve the only possible reprieve. I have felt relief many times in my life, but except possibly for the safe birth of my children, nothing like that. I was in a chemo chair when they came by and told me. I called my wife and said, I have a donor, and I started to cry.

Patients in the transplant ward talk a lot about our donors, despite not knowing who they are. Everybody everybody! tears up when talking about their donors.

True story: I was in the hallway on the transplant floor, talking with the woman in the room next to mine. A nurse walking by stopped and said, Mr. Lazarus, are you having trouble with allergies? (which would require attention). I said no, I was talking about my donor. No other explanation needed. She patted my arm and walked on.

I am a chimera. The rest of me has my own DNA, but my blood cells carry my donors DNA, not mine. Somebody elses blood pumps through my body, keeping me alive, not just through treatment, but every second of every day for the rest of my life. How can you not be grateful to someone who literally gave you the rest of your life?

At some point during the 24 hours after I was unhooked from the machine, a volunteer courier arrived at the hospital in Boise. He or she or they retrieved the bag of my donated cells, flew with it to wherever the recipient is located, and hand-delivered it to his hospital. The patient almost certainly received the transplant before I made it back to Los Angeles. If all goes well, my stem cells will navigate their way into his bone marrow, where theyll settle in, multiply, and start producing healthy blood cells. If all goes well, this perfect stranger will eventually have my blood type, and potentially even my childhood immunitieshe might soon, in other words, have my immune system. If all goes well, may that sucker protect us both.

Headaches, confusion and delirium with COVID-19: How SARS-CoV-2 attacks the brain – Firstpost

Friday, September 11th, 2020

The ACE2 receptor that the virus targets is rare in the brain. But new research shows that the virus could enter brain cells via this method too.

The coronavirus targets the lungs foremost, but also the kidneys, liver and blood vessels. Still, about half of patients report neurological symptoms, including headaches, confusion and delirium, suggesting the virus may also attack the brain.

A new study offers the first clear evidence that in some people, the coronavirus invades brain cells, hijacking them to make copies of itself. The virus also seems to suck up all of the oxygen nearby, starving neighboring cells to death.

Its unclear how the virus gets to the brain or how often it sets off this trail of destruction. Infection of the brain is likely to be rare, but some people may be susceptible because of their genetic backgrounds, a high viral load or for other reasons.

If the brain does become infected, it could have a lethal consequence, said Akiko Iwasaki, an immunologist at Yale University who led the work.

The study was posted online Wednesday and has not yet been vetted by experts for publication. But several researchers said it was careful and elegant, showing in multiple ways that the virus can infect brain cells.

Scientists have had to rely on brain imaging and patient symptoms to infer effects on the brain, but we hadnt really seen much evidence that the virus can infect the brain, even though we knew it was a potential possibility, said Dr. Michael Zandi, consultant neurologist at the National Hospital for Neurology and Neurosurgery in Britain. This data just provides a little bit more evidence that it certainly can.

Zandi and his colleagues published research in July showing that some patients with COVID-19, the illness caused by the coronavirus, develop serious neurological complications, including nerve damage.

In the new study, Iwasaki and her colleagues documented brain infection in three ways: in brain tissue from a person who died of COVID-19, in a mouse model, and in organoids clusters of brain cells in a lab dish meant to mimic the brains three-dimensional structure.

The coronavirus is much stealthier: It exploits the brain cells machinery to multiply, but doesnt destroy them. Instead, it chokes off oxygen to adjacent cells, causing them to wither and die.

The researchers didnt find any evidence of an immune response to remedy this problem. Its kind of a silent infection, Iwasaki said. This virus has a lot of evasion mechanisms.

These findings are consistent with other observations in organoids infected with the coronavirus, said Alysson Muotri, a neuroscientist at the University of California, San Diego, who has also studied the Zika virus.

The coronavirus seems to rapidly decrease the number of synapses, the connections between neurons.

Days after infection, and we already see a dramatic reduction in the amount of synapses, Muotri said. We dont know yet if that is reversible or not.

The virus infects a cell via a protein on its surface called ACE2. That protein appears throughout the body and especially in the lungs, explaining why they are favoured targets of the virus.

Previous studies have suggested, based on a proxy for protein levels, that the brain has very little ACE2 and is likely to be spared. But Iwasaki and her colleagues looked more closely and found that the virus could indeed enter brain cells using this doorway.

Its pretty clear that it is expressed in the neurons and its required for entry, Iwasaki said.

Her team then looked at two sets of mice one with the ACE2 receptor expressed only in the brain, and the other with the receptor only in the lungs. When they introduced the virus into these mice, the brain-infected mice rapidly lost weight and died within six days. The lung-infected mice did neither.

Despite the caveats attached to mouse studies, the results still suggest that virus infection in the brain may be more lethal than respiratory infection, Iwasaki said.

The virus may get to the brain through the olfactory bulb which regulates smell through the eyes or even from the bloodstream. Its unclear which route the pathogen is taking, and whether it does so often enough to explain the symptoms seen in people.

I think this is a case where the scientific data is ahead of the clinical evidence, Muotri said.

Researchers will need to analyse many autopsy samples to estimate how common brain infection is and whether it is present in people with milder disease or in so-called long-haulers, many of whom have a host of neurological symptoms.

Forty percent to 60% of COVID-19 patients experience neurological and psychiatric symptoms, said Dr. Robert Stevens, a neurologist at Johns Hopkins University. But the symptoms may not all stem from the virus invading brain cells. They may be the result of pervasive inflammation throughout the body.

For example, inflammation in the lungs can release molecules that make the blood sticky and clog up blood vessels, leading to strokes. Theres no need for the brain cells themselves to be infected for that to occur, Zandi said.

But in some people, he added, it may be low blood oxygen from infected brain cells that triggers strokes: Different groups of patients may be affected in different ways, he said. Its quite possible that youll see a combination of both.

Some cognitive symptoms, like brain fog and delirium, might be harder to pick up in patients who are sedated and on ventilators. Doctors should plan to dial down sedatives once a day, if possible, in order to assess COVID-19 patients, Stevens said.
