To Your Good Health: A flu shot is the best way to prevent the flu – Arizona Daily Star

Monday, December 2nd, 2019

DEAR DR. ROACH: Ive caught a flu. Thats despite taking vitamin C, garlic and oil of oregano. I gave up on echinacea a long time ago. I try to get enough rest and live a relatively healthy life. I take no prescription drugs, and youd think at age 59 Id have built immunity to the latest bug.

If theres a cold or flu circulating, I always get it. Why do I have such a bad immune system? I am diligent with handwashing and hygiene, but still, I get sick. Could it be related to extreme stress in childhood, which diminished my immune system? S.M.

ANSWER: Influenza, the flu, is a contagious virus. Keeping your hands clean provides some protection, but the virus can be transmitted through the air in addition to hand-to-hand contact. The best way of improving your immunity to influenza is by taking the vaccine, which changes every year to best match the strains that are expected to circulate. The vaccine provides only partial protection. Its still possible to get the flu after vaccination, but any protection is helpful. The vaccine helps reduce hospitalizations and deaths from influenza.

High amounts of stress do take their toll on the immune system, although I dont know of proof that stress in childhood would affect you 50 years later. Unfortunately, vitamin C, garlic, oregano, echinacea and other supplements have limited if any value in preventing influenza or any of the other viruses that cause respiratory symptoms during the colder months.

DEAR DR. ROACH: I have been taking ranitidine successfully for years to treat acid reflux. Recently I have read some very scary things about a chemical in it, and some drugstores are pulling Zantac off the shelves. I have heard nothing from my doctor so far. I am wondering what my options are and if the ranitidine scare is warranted. In the past I have used PPIs with success, but stopped when I heard a lot of alarming data about long-term use. J.R.

ANSWER: In September 2019, the Food and Drug Administration found evidence of small quantities of a contaminant, NDMA, in generic forms of ranitidine. Brand-name Zantac has also now been recalled. NDMA is a probable carcinogen, although the amount present in medications (the contaminant has also been found in some heart medications, the angiotensin receptor blockers) is so small that it is unlikely to cause significant harm in the short term.

Until noncontaminated ranitidine is available, there are other over-the-counter options, such as famotidine (Pepcid is the common brand name).

My major concern about taking ranitidine and medicines like it called H2 blockers, for the histamine type 2 receptor, which stimulates acid production for years is that the acid reflux you have been treating might be something more concerning. People who have had persistent symptoms should be periodically reevaluated and considered for an upper endoscopy.

I routinely hear from people who have really made a significant change in lifestyle and were able to stop medication entirely. Identifying and stopping dietary triggers, not eating a couple of hours before bed, elevating the head of the bed and, for some people, losing weight are among the most effective behavioral strategies.

Accelerating personalized animal immunotherapy research – SelectScience

Monday, December 2nd, 2019

Ferris El-tayyeb discusses the challenges of animal oncology, the lab equipment helping to accelerate progress towards personalized immunotherapies, and his hopes for the future

For decades, cell counting has been a fundamental lab technique performed in a variety of research fields. Traditionally performed manually using a brightfield microscope, the process can be laborious and human error can cause data to be inaccurate. As labs have streamlined processes and technology has advanced, new equipment has been introduced to enable faster, easier and more reliable results for cell counting. In this SelectScience interview, Ferris El-tayyeb, Associate Researcher at Torigen Pharmaceuticals, discusses the teams research on the development of personalized immunotherapies for animals and reveals the impact the LUNA-FL Dual Fluorescence Cell Counter from Logos Biosystems has had in accelerating this work.

FE: My name is Ferris El-tayyeb, I am a recent graduate of the University of Connecticut and currently an associate researcher with Torigen labs research and development department.

FE: Torigen Pharmaceuticals uses autologous cancer immunotherapy to create a series of vaccines to present tumor-associated antigens back to the immune system. These vaccines produce a heightened immune response within the animal against tumor antigens and, as such, allow the animals own immune system to produce a response against the tumor. Currently, we are working on improving the efficacy of the adjuvant and looking at different vectors to heighten immune presentation.

FE: In all forms of oncological research, an issue is consistency. Cancers, in general, are so vastly different in their presentation and properties that its difficult to find a catch-all treatment that all cancers respond to. This is something we think about at Torigen labs as the personalized nature of the vaccines ensures that the immune response elicited is specific to the tumor phenotype.

LUNA-FL Dual Fluorescence Cell Counterby Logos Biosystems

Equipped with brightfield and dual fluorescence optics that allow the sensitive detection of most cell types,the LUNA-FL can distinguish primary cells from undesirable debris for accurate cell count and viability results.

FE: We use the LUNA-FL for a variety of applications within the lab. The first example is for cell culturing to determine how many cells we have and how many flasks we should split into. Then we also use it for peripheral blood mononuclear cell (PBMC) isolation to quantify our yield and viability for R&D sample collection. Finally, we use it after processing samples to determine the effectiveness of our mechanical dissociation of the tumor.

FE: The LUNA-FL has made it dramatically easier to count cells. Before joining Torigen labs, my former laboratory would count cells under a brightfield microscope. While not impossible, solutions with high cell count make it incredibly difficult to get an accurate cell count. The LUNA-FL surmounts this by allowing you to get fast and easy cell/viability counts without the slow and tedious method of counting by hand.

FE: I personally would, the time saved by counting cells electronically can be better used preparing for the next step of the process of analyzing data, rather than sitting hunched over a microscope for hours on end. With an AO/PI stain, it is infinitely easier and faster than hand counting as well as giving accurate results.

FE: There are many challenges in the field of animal oncology, much like with human oncology. Treatments are often specific and affect specific pathways within tumor types that may not be present in others. On top of this, the popular broad-spectrum treatments of chemotherapy and radiation often lead to discomfort for the animal. In the future, it would be nice to see broad spectrum personalized immuno-oncology treatments that lead to minimal discomfort, something Torigen labs is working to develop currently.

Coming soon: Early nextyear, Logos Biosystems will launch the newest member of the LUNA family, designed to build on the success of its predecessors:the LUNA-FX7 Automated Cell Counter.

Be good to your gut – India Today

Monday, December 2nd, 2019

At a health workshop titled The Happy Gut, nutritionist Rebekah Blank explained rather jovially how all diseases begin in the gut. A famous saying, it wasnt lost on the dozen odd people who had gathered around her at a popular caf in Noida.

The gut is the centre of our immune system and one of the most important organs of the body. Our gut is where we digest our food and where we assimilate the nutrients into the rest of our body to nourish ourselves. "A good gut means a healthy functioning digestive system. It means we are getting proper nutrition from the food we are eating, that we have good energy, we dont have toxins leaking into our bodies and last but not the least we have strong immune systems," explained Blank, brand head, Fabcafe by Fabindia.

TUMMY TALES

The gut consists of approximately 80 per cent of the immune system and 95 per cent of serotonin or the "feel-good" hormone, is also produced here. "An individuals intestines [gut] contain pounds of good bacteria, whose job is to help with the absorption of nutrients from the food you eat. The good bacteria determines the strength of your immunity, regulates weight, recovery, healing, colon health, toxicity in the body and several other functions," says a nutritionist with GOQii, a preventive healthcare company.

The issues around gut health only seem to be increasing year on year, indicating a downward trend in Indias health as far as nutrition is concerned.

According to the GOQii India Fit Report released earlier this year, gut health is an area of key concern. The report indicates 35 per cent of the users having concerns regarding acidity and indigestion. Constipation is plaguing 14 per cent of them, which is higher than the last year by 10 per cent. Bloating too has increased from 8.5 to 10 per cent.

Its quite clear why the tummy is in trouble. Bacteria, fungi and virus, collectively called microbiome, exist in the gastrointestinal tract and for a body to function properly, it must maintain the right balance of bacteria in the gut. But our modern lifestyle results in most of our health problems. "Stress, anxiety, high blood sugar, insomnia, inappropriate eating habits and intake of processed food and the consumption of antibiotics can damage the gut microbiome," says Mohamad Yusuf N Shaikh, founder of Kudrati Ayurved Health Center.

Leaky Gut, which is one of the most bewildering illnesses to be diagnosed and treated. It is puzzling majorly due to the gut having a very extensive and complex structure. Due to this, toxins and bacteria enter the blood-stream, resulting in inflammation and activating a reaction from the immunity. "This is one of the major causes of several medical conditions such as chronic fatigue syndrome, migraine, multiple sclerosis, fibromyalgia, food sensitivities, thyroid abnormalities, mood swings and skin conditions," informs the GOQii nutritionist.

According to Delhi-based dietician Nmami Agarwal, deep-fried foods and those made of refined flour and refined sugar make a harmful combination for our gut. "Also, alcohol and smoking can irritate your digestive system and give rise to acidity. To maintain a healthy gut, you need to follow a balanced diet with an optimum combination of macro and micronutrients," she says.

However there are several ways in which we can keep our gut clean. One of them is to have correct food pairings. As digestion is a complex process from breaking down of the starch to activating enzymes that dismantle proteins it is necessary to follow proper food pairing for a healthy gut. Certain nutrients are better absorbed when they are eaten together, for example, to get more calcium from yoghurt, one can increase the intake of foods with high vitamin D, such as salmon.

FOOD PAIRING

"Raw fats, like olive and coconut oil or even avocado, can prevent the digestion of protein because fats make the gut environment basic, and avoid the full breakdown of proteins that results in an acidic stomach," informs Shaikh. Do not pair protein with starch because proteins need an acidic environment to break down and starches need an alkaline for basic environment. "Pairing these together will make the stomach to go into over function and will leave you feeling tired, bloated and gassy," he adds.

Yoghurt comprises probiotics which ensures good bacteria growth in Gastrointestinal. Probiotics are foods, or food supplements, that contain live bacteria suitable for health. Besides, drinking water keeps the body hydrated, helps in digestion and prevents constipation. "Intake of prebiotics fibre such as fruits, vegetables and whole-grain can helps in building a healthy gut in the long run," says Shaikh.

Its important that attention to the stomach is paid right from a young age. "Proportion of good bacteria is maintained at all times, especially in children. A shortage of these can also be the leading cause of allergies, skin problems, migraines, inability to lose weight," says GOQii nutritionist.

In a nutshell, reduce the intake of refined carbohydrates, include probiotic supplements and eat fermented and high fibre foods, reduce the intake of alcohol and quit smoking.

The ketogenic diet may help fight against the flu – Big Think

Monday, December 2nd, 2019

The low-carb, high-fat ketogenic diet might not just be good for your waistline; it could also keep you healthy this flu season. Yale University researchers discovered that mice who were fed a ketogenic diet were better at fighting off flu infections that those fed a high-carb diet instead.

People can use the keto diet to quickly lose weight by capitalizing on a metabolic state called ketosis. Normally, the human body gets most of its energy from glucose (i.e., blood sugar) derived from carbohydrates, but the body doesn't have a good way of storing glucose. Because of this, the humans need an alternative energy source to get them through periods when they can't get access to any food. Once the body is deprived of glucose, the liver begins to break down fat into an alternative energy source called ketones that can keep the body going long after it last ate.

Luckily, we can jump into this metabolic state without having to actually starve ourselves by simply eating no or very little carbohydrates eating more fats and proteins keeps us feeling full while our bodies still burn fat to make ketones.

Interestingly, the keto diet seems to have a lot more effects other than weight loss. Ketosis appears to have wide-ranging effects throughout the body, with potential beneficial outcomes for diabetics and epileptics. There's also some evidence suggesting a correlation between the keto diet and improved mental health and better outcomes in cancer treatments though the research is still far from conclusive.

The researchers discovered that a keto diet appeared to activate genes that produce a specialized type of immune cells called gamma delta T cells. Tissue samples from the lungs of mice in the keto group confirmed that they had higher levels of these cells. The researchers suspected that these elevated levels of gamma delta T cells killed infected cells in the mice's lungs, and they also appeared to increase mucus production in the lungs, helping to trap more of the virus.

Furthermore, when the researchers fed a keto diet to mice specially bred to lack the genes that code for gamma delta T cells, the diet had no effect on their survivability, confirming that ketosis was somehow upregulating these genes.

Further experiments confirmed that ketosis itself, rather than just a low-carb diet, seemed to be the triggering factor. The researchers fed some mice a high-fat diet with less carbs than the standard diet but more than the keto one. Specifically, the keto diet contained less than 1 percent carbs, the standard diet contained 58 percent carbs, and the high-fat, high-carb diet contained 20 percent carbs. While the high-fat, high-carb diet did elevate gamma delta T cell levels, it did not appear to do so to the degree where any benefit could be gained.

While this exciting finding does suggest that the keto diet may help you power through flu season, it's important to remain realistic. For one, this study was conducted on mice, not humans. Animals respond differently to both treatments and diseases than humans do, and some researchers have found that animal trials tend to be conducted under different circumstances than human trials and can be less rigorous as well, sometimes resulting in biased findings.

What's more, the keto diet may come with many health benefits, but its also not without its risks. The high meat component of the keto diet can damage your kidneys and cause gout, and the diet's restrictive nature can lead to vitamin deficiencies. It ought not need to be said, but pregnant women and young children shouldn't be put on the keto diet the diet tricks your body into thinking it's starving, which is not ideal for development.

Ironically, quickly switching from your normal diet to a keto one can actually give you flu-like symptoms. The "keto flu" is a temporary side effect of rapidly removing carbs from your diet that can cause nausea, headaches, weakness, issues with concentration, and other symptoms. Hardly ideal if you're trying to stay ahead of the flu bug!

Fortunately, most of these negative effects can be mitigated or avoided by building a healthy keto meal plan and transitioning gradually into a keto diet. Undertaking any diet with the goal of improving your health will require doing some homework to figure out what works, and the keto diet is no exception. It's also important to remember that the keto diet probably works best as a short-term diet. Few people can stick with the diet over the long term, so hard evidence on its long-term impacts is scant, but it's unlikely that excluding healthy components of a normal diet (like fruit) would be sustainable. That being said, if these findings are verified, then it might not be a bad idea to try the keto diet once flu season rears its ugly head once again.

World AIDS Day 2019: 37.9M people worldwide were living with HIV at the end of 2018 – USA TODAY

Monday, December 2nd, 2019

When HIV exploded in the 1980s, scientists had no idea what was making patients so sick. So, what have scientists figured out since then? We explain. Just the FAQs, USA TODAY

People around the world on Sunday observed the 31stannual World AIDS Day, an eventfirst declared in 1981 aimed atraising awareness of the HIV/AIDS epidemic. It was first declared by the World Health Organization.

According to the Joint United Nations Programme on HIV/AIDS (UNAIDS), 37.9 million people around the world were living with HIV at the end of 2018. UNAIDS reports 1.7 million people worldwide were newly infected in 2018.

The Centers for Disease Control and Prevention reports 1.1 million people were living with HIV in the United States at the end of 2016 and 1 in 7 people nationwide who had the disease didnt know they were infected.

According to the CDC, 37,832 people received an HIV diagnosis in the United States and dependent areas.

Worldwide, 770,000 people died from AIDS-related illnesses in 2018, according to UNAIDS. The CDC reports there were 16,350 deaths among people diagnosed with HIV in the United States. The agency added the deaths may be due to any cause.

HIV stands forhuman immunodeficiency virus. AIDS stands for acquired immunodeficiency syndrome.

HIV is a virus that can lead to AIDS.AIDS is the lastof thethree stages of HIV infection.

According to the CDC, people in the first stage, acute HIV infection, experience a flu-like illness within 2 to 4 weeks after infection.Itcan last a few weeks. People in this stagehavelarge amounts of the virus in their blood,and so are more likely to transmit the infection.

The second stage, clinical latency, marks a period where the virus is active but reproduces only at low levels, HIV.gov says. People in this stagemight not experience symptoms but can still transmit HIV to others. This stage can last decades, depending on treatment, but can also be shorter.

AIDS, the third stage,leads to the mostsevere illnessesbecause the virus damages the immune system over time, the CDC says. On average, people with AIDS who don't get treatment survive three years, according to the CDC.

Treatment at all three stagescan prevent or slow symptoms and reduce the risk of transmission, the CDC says.

Testing is the best way to determine whether you have HIV, but symptoms can occur beforeHIV shows up on a test. Some experience flu-like symptomsincludingfever, chills, rash, night sweats, muscle aches, sore throat, fatigue, swollen lymph nodesor mouth ulcerswithin two weeks of infection.

HIV attacks your immune system by reducing CD4 cells, or T cells, makingit harder to fight other infections."Over time, HIV can destroy so many of these cells that the body cant fight off infections and disease," according to HIV.gov.

According to HIV.gov, the condition becomesAIDS whenT cellcounts drop below200 cells per cubic millimeter of blood,or certain AIDS-related complications suchassevere infectionsappear.

A person can become infected with HIV only through certain activities in which they come intocontact with certain bodily fluids.

Blood, semen, pre-seminal fluid, rectal fluids, vaginal fluidsand breast milk can transmit HIV, according to the CDC.

"These fluids must come in contact with a mucous membrane or damaged tissue or be directly injected into the bloodstream (from a needle or syringe) for transmission to occur," the CDC says.

Unprotected anal or vaginal sex with someone who has HIV is one of two main ways the virus is spread in the United States, according to HIV.gov. The use of a contaminated needle or syringe is the other.

A mother may pass the virus on to her child duringpregnancy, birthor breastfeeding. It can also be contracted bybeing struck by an item contaminated with HIV. Other rare but possible ways to spread HIV can be found here.

U.S. scientists found the first clinical evidence for the disease that would become known as AIDS in 1981, according to the United Nations. Chimpanzees in Central Africa have been identified as the source of HIV in humans. Their version of the virus, calledSIV,was likely transmitted to humans and then mutated, the CDC says. HIV has existed in the United States since the mid- to late 1970s.

Yes. People with HIV can take a series of drugs, called antiretroviral therapy, or ART,that slows the virus from progressing, keeps them healthy for years and drastically reduces their likelihood of spreading the virus, the CDC says.

Not yet. Researchers are working toward a cure. Ifa cure were to be found, it'd likely take one of two forms, according tothe National Institute of Allergy and Infectious Diseases (NIAID).

Viral eradication would mean HIV was eliminated from a patient's body. The approachwould involve "prodding the virus out of its latent state so that an enhanced immune system or administered therapies can target and eliminate HIV-infected cells," the NIAID says. Researchers are also studying gene mutations in certain people whose immune cells resist HIV.

A functional cure, or sustained ART-free remission, would mean that HIV wasnot eliminated, but rather suppressed to a point at which daily medication would no longer be longer required.

No, but there have been a number of developments. The National Institutes of Health (NIH) opened the first clinical trial with138 healthy, HIV-negative volunteers in 1987, according tothe NIAID.

In 2016,the NIH announced avaccine-efficacy trial in South Africa of 5,400 people, the largest in the country's history. Researchers are building on a 2009 success in Thailand, where for the first time ever a vaccine showed modest success in preventing HIV infections.

The CDC recommends everyone from ages 13 to 64 get tested at least once.

People at greater risk of infection, such as sexually active gay or bisexual men, people who have had sex with an HIV-positive partner, people who have shared needles and sex workers, among othersshould get tested more often.

The CDC recommends testing once a year for people engaging in these higher-risk behaviors. Forsexually active gay and bisexual men, the CDC says testing every three to six months is beneficial.

If you are pregnant, and even if you are in a monogamous relationship, the CDC recommends testing to be sure and to reduce the risk of transmitting HIV to your child or partner. The sooner a pregnant woman starts treatment, the less likely she is to transmit HIV to her child.

Most HIV tests involve blood or oral fluid. Clinics, hospitals, community health centers and many other locations provide HIV testing. Home testing equipment is also available.

HIV does not always show up right away in a test. Your body and the test type determinehow long HIV can take to be detected. Here's a useful guide from theSan Francisco AIDS Foundation on testing windows.

For more information on local testing sites,call1-800-CDC-INFO (1-800-232-4636) or

visitgettested.cdc.gov.

The red ribbon was created in 1991 by artists in New York workingto increase awareness of HIV/AIDS. The artists saw the red ribbon as an easy-to-copy way to show compassion for those living with HIV, given the stigma surrounding it.

"They chose red for its boldness, and for its symbolic associations with passion, the heart and love," according toWorld AIDS Day organizers.

First-in-kind Human 3-dimensional Models of Parkinson’s Disease and Progressive Multiple Sclerosis Launching to the International Space Station -…

Monday, December 2nd, 2019

LOUISVILLE, Ky.--(BUSINESS WIRE)--The National Stem Cell Foundation (NSCF) announced today that research teams from Aspen Neuroscience and the New York Stem Cell Foundation (NYSCF) Research Institute will send a first-in-kind study of neurodegenerative disease to the International Space Station (ISS) on the nineteenth SpaceX Commercial Resupply Services (CRS-19) mission, scheduled to launch December 4th from the Kennedy Space Center in Cape Canaveral, Florida. This is the second space flight for the research teams. A preliminary experiment was launched to the ISS in July 2019 onboard SpaceX CRS-18 to test custom flight hardware systems and refine post-flight analytical methods in preparation for the SpaceX CRS-19 launch.

The NSCF-funded collaboration between researchers at the NYSCF Research Institute and Aspen Neuroscience will perform the first study of long-term cell cultures of patient-derived induced pluripotent stem cell (iPSC) neural organoids with microglia on the ISS to study Parkinsons disease and primary progressive multiple sclerosis in microgravity. The ability to observe cell interaction, cell signaling, migration, changes in gene expression and the common pathways of neuroinflammation for both diseases in microgravity provides an opportunity to view the biological processes in a way that is not possible on Earth. This innovative approach to modelling disease has the potential to provide valuable new insight into the fundamental mechanisms underlying neurodegenerative disorders that may accelerate biomarker discovery and potential new drug and cell therapy options for patients. These models also offer potential for better translational study and future personalized medicine applications.

The development of patient-specific, 3-dimensional human organoids that incorporate microglia (the inflammatory cells of the immune system implicated in the development of Parkinsons, MS and other neurodegenerative diseases) for observation and study in the unique research environment of microgravity has the potential to enable progress across the field for a wide variety of conditions that affect a significant portion of the global population. The engineering required to facilitate the transport of cells and culture on orbit is being led by space flight engineering partner Space Tango.

Dr. Paula Grisanti, CEO of NSCF said, Supporting this collaboration between world-class research teams during a time of explosive growth in our understanding of the research advances possible in space is a great privilege. We are delighted to be funding such innovative science at the frontier of new drug and cell therapy discovery.

We are thrilled to be working with such a comprehensive team of scientists and fantastic organizations and feel honored to use our technology to better understand neurodegenerative disorders affecting so many persons globally, said Dr. Andres Bratt-Leal, Vice President of Research and Development, Aspen Neuroscience.

We feel privileged to have the opportunity to help understand the behavior of neural cells in microgravity and to help model neurodegenerative disease in such a novel way. We are excited about this fantastic project and look forward to learning the results, said Dr. Jeanne Loring, Chief Scientific Officer, Aspen Neuroscience.

We are excited to collaborate on the first study of progressive multiple sclerosis and Parkinsons patient brain cells in space. This work will provide important insights into the mechanisms behind these diseases and advance targets for future treatments," noted Susan L. Solomon, NYSCF Chief Executive Officer.

There is significant potential to advance our understanding of MS and PD as we initiate these long-term studies of patient cells in microgravity now that we have completed our preliminary tests, said Dr. Valentina Fossati, NYSCF Senior Research Investigator. We look forward to leveraging the unique capabilities of spaceflight research to better understand the role of microglia in multiple sclerosis and Parkinsons disease, as well as how dysfunction in these cells can be targeted therapeutically.

It takes vision, passion, and courage to change the paradigms of current understanding, said Jana Stoudemire, Commercial Innovation Officer at Space Tango. We are honored to support the groundbreaking work of the National Stem Cell Foundation and these recognized leaders in stem cell biology. Their commitment and dedication to advancing the frontiers of science using new tools and new approaches has been inspiring to witness, and has the potential to provide an entirely new perspective on Parkinsons and progressive MS.

What To Eat When You Have a Cold – theLoop

Monday, December 2nd, 2019

Sponsored Post

With the cold and flu season upon us, there are other protective measures we can take beyond just regularly washing our hands. Food is powerful medicine that can kick our immune systems into gear, both to fend off viruses as well as reduce the severity and duration of symptoms such as congestion, sore throat and fatigue.

I often prescribe these essentials as part of any cold-sufferers diet:

Garlic

Garlic has been studied for centuries for its anti-bacterial properties. When garlic is sliced, chewed or crushed, sulfur compounds such allicin, diallyl disulfide, vinyldithiins and s-allyl cycteine are activated (giving off that distinctive garlic smell). These have been shown to support the disease-fighting response of some types of white blood cells, helping them to fight viruses. Garlic can also be taken as a preventative supplement: I recommend 300 mg a day, or incorporating one to two fresh cloves daily into your diet, including in salad dressings, green juices, or simply rubbing it on whole grain bread for delicious flavored toast.

Chicken Soup

Good, old fashioned chicken soup has been used forever as a common cold aide and there are some real benefits. The warm broth can help alleviate congestion and the electrolytes (sodium) found in the broth can help keep you hydrated and soothe a sore throat. The added chicken and vegetables provide additional protein and nutrients, with carrots, celery, onion, turnip and fresh herbs supplying an even bigger nutritional boost.

Tea

When you arent feeling your best, warm fluids can soothe that scratchy throat and help to loosen mucus. Opt for decaffeinated tea as caffeine is dehydrating, which is the last thing you need when you are trying to flush a virus from your system. I always recommend ginger tea, as it can soothe a stomach thats upset from loose mucus draining into the digestive system. Ginger also has anti-inflammatory properties that assist with immune function.

Non-Fat Greek Yogurt

Loaded with live cultures and probiotics, yogurt helps to keep your gut lining healthy. Approximately 70% of our immune system is located in our gut, so it is important to keep it in good fighting shape in case your body encounters a virus. Consuming probiotic rich foods can lower the risk of catching a cold and help to speed recovery if you have caught one. Another perk, non-fat Greek yogurt has triple the protein of regular yogurt (without the added sugar).

Red Bell Peppers

Vitamin C is essential for the function of immune cells, and during infections our bodies quickly become deficient of this vitamin. Eating foods rich in vitamin C during a cold or virus can speed the bodys recovery and reduce symptoms. Since vitamin C is water soluble, its more efficient to consume it through foods high in vitamin C, such as red bell peppers, rather than from solid supplements which require more work for the body to digest and absorb. One cup of chopped red bell pepper contains 190 mg of this important vitamin. Other foods high in vitamin C include kiwifruit, broccoli, dark leafy greens and citrus fruits.

Blueberries

Blueberries are a great source of anthocyanins, a type of flavonoid that gives the berry (and other colorful fruits and vegetables) its rich, deep color. Flavinoids have anti-inflammatory, anti-bacterial and antioxidant properties that can help reduce cell damage and boost immune function. A powerhouse berry thats low in calories, you can snack on them, add to salads or treat yourself to a crumble.

Study: For babies born with HIV, start treatment right away – amNY

Monday, December 2nd, 2019

When babies are born with HIV, starting treatment within hours to days is better than waiting even the few weeks to months thats the norm in many countries, researchers reported Wednesday.

The findings, from a small but unique study in Botswana, could influence care in Africa and other regions hit hard by the virus. They also might offer a clue in scientists quest for a cure.

The Harvard-led team found super early treatment limits how HIV takes root in a newborns body, shrinking the reservoir of virus that hides out, ready to rebound if those youngsters ever stop their medications.

We dont think the current intervention is itself curative, but it sets the stage for future attempts, said Dr. Daniel Kuritzkes of Bostons Brigham and Womens Hospital, who co-authored the study.

Giving pregnant women a cocktail of anti-HIV drugs can prevent them from spreading the virus to their unborn children, a step that has dramatically reduced the number of babies born with the virus worldwide. Still, some 300 to 500 infants are estimated to be infected every day in sub-Saharan Africa.

Doctors have long known that treating babies in the first weeks to months of life is important, because their developing immune systems are especially vulnerable to HIV. But an infant dubbed the Mississippi baby raised a critical question: Should treatment start even earlier? The girl received a three-drug combination within 30 hours of her birth in July 2010, highly unusual for the time. Her family quit treatment when she was a toddler yet her HIV remained in remission for a remarkable 27 months before she relapsed and restarted therapy.

The Botswana study was one of several funded by the U.S. National Institutes of Health after doctors learned of the Mississippi baby, to further explore very early treatment.

The findings are encouraging, said Dr. Deborah Persaud, a pediatric HIV specialist at Johns Hopkins University who wasnt involved with the Botswana study but helped evaluate the Mississippi baby.

The study showed what we hypothesized happened in the Mississippi baby, that very early treatment really prevents establishment of these long-lived reservoir cells that currently are the barrier to HIV eradication, Persaud said.

She cautioned: Very early treatment is important, but prevention should still be our top priority.

In Botswana, researchers tested at-risk newborns, enrolling 40 born with HIV, treating them within hours to a few days, and tracking them for two years. On Wednesday, they reported results from the first 10 patients, comparing them with 10 infants getting regular care treatment beginning when they were a few months old.

Medication brought HIV under control in both groups. But the children treated earliest had a much smaller reservoir of HIV in their blood, starting about six months into treatment, the researchers reported in Science Translational Medicine.

The earliest-treated children also got another benefit: more normal functioning of some key parts of the immune system.

One big question: Did the HIV reservoir shrink enough to make a long-term difference? To find out, next year the researchers will give these children experimental antibodies designed to help keep HIV in check, and test how they fare with a temporary stop to their anti-HIV drugs.

In the U.S., Europe and South Africa, its becoming common to test at-risk infants at birth. But in most lower-income countries, babies arent tested until theyre 4 to 6 weeks old, said study co-author Dr. Roger Shapiro, a Harvard infectious disease specialist.

MS Risk Linked to Herpes Virus 6A and Not More Common 6B, Study Suggests – Multiple Sclerosis News Today

Monday, December 2nd, 2019

Human herpesvirus 6A (HHV-6A), but not awidespread variant of the virus called HHV-6B, could be one of the root causes of multiple sclerosis (MS), new research suggests.

Compared to healthy people, those with MS show greater numbers of antibodies to HHV-6A viruses, reflecting greater exposure to this type of infection and suggesting a link to this disease.

The study reporting these findings, Increased serological response against human herpesvirus 6A is associated with risk for multiple sclerosis, was published in the journal Frontiers in Immunology.

While the origin of MS remains unclear, research has proposed that viral infections by HHV-6 could be one of its causes.

The hypothesis is that the virus is able to mislead the immune system into attacking the bodys own tissues, damaging the brain and spinal cord.However, it has been impossible to say which specific type of the virus 6A or 6B is responsible for such risk.

HHV-6B is a very common virus acquired early in life. About 80% of all children are estimated to be infected before the age of 2. In children, HHV-6B can cause relatively mild conditions such as roseola, an illness marked by days of high fever, rashes, and, in some cases, febrile seizures.

Less is known about the consequences of HHV-6A, although this specific variant has been linked with MS.

Upon exposure to HHV-6, a persons immune system raises antibodies against specific viral proteins, which help to protect them against the virus for the rest of their lives. The presence of these specific antibodies can be tested in blood samples to find whos been exposed to the virus.

As HHV-6A and HHV-6B are extremely similar, it has not been possible to date to determine which of these herpes viruses the antibodies are reacting against when a person tests positive for this viral infection through a blood test.

Scientists at theKarolinska Institutet in Sweden devised a way to overcome this problem.

They were able to distinguish between 6A and 6B types by measuring antibodies in the blood that recognize the proteins that diverge most between the two viruses called immediate early protein 1A and 1B (IE1A and IE1B).

Researchers compared antibody levels in blood samples of 8,742 people with MS and 7,215 healthy people, all in Sweden and matched for gender, date of birth, and other factors.

Results showed that MS patients had a 55% higher risk of carrying antibodies against HHV-6A than healthy people.

Further analysis in a group of 478 patients whose blood samples were collected before the onset of MS showed that viral infection by HHV-6A more than doubled a persons risk of developing MS later on.

Researchers also saw that the younger the age at which patients tested positive for the HHV-6A virus, the higher the risk of MS.

In contrast, carrying antibodies against HHV-6B was not associated with MS development. In fact, MS patients tended to have lower amounts of antibodies against this type of virus than people without this disease.

This is a big breakthrough for both the MS and herpes virus research, Anna Fogdell-Hahn, an associate professor at Karolinska and one of the studys senior authors, said in a news story.

For one, it supports the theory that HHV-6A could be a contributing factor to the development of MS. On top of that, we are now able, with this new method, to find out how common these two different types of HHV-6 are, something we havent been able to do previously, Fogdell-Hahnadded.

Infection by another herpes virus, called Epstein-Barr virus (EBV) and best known as the cause of mononucleosis, also has been proposed as a risk factor for MS.

Researchers analyzed antibodies against EBV, and observed that individuals affected with both viruses EBV and HHV-6A had an even higher risk of developing MS.This indicates that multiple viral infections can act together to raise a persons susceptibility to the disease.

Both HHV-6A and 6B can infect our brain cells, but they do it in slightly different ways. Therefore, it is now interesting to go forward and attempt to map out exactly how the viruses could affect the onset of MS, Fogdell-Hahn said.

A cause-effect relationship between the virus and MS, however, is not by any means established, and more studies are needed, the team emphasized.

Colby Cosh: Barbarous right-wing cost-chopping … pioneered by the B.C. NDP? – National Post

Monday, December 2nd, 2019

My New Democratic MLA, David Shepherd, was in the local paper Monday morning. Davids a pleasant fella, and I always feel awkward exposing Edmonton news items like worn-out ginch to a national audience, but he has presented an example of something that happens all across the country, all the time, and that ideally wouldnt, or shouldnt.

You see, there was a small protest at the Alberta legislature on Sunday. The hundred or so protesters were sufferers (and friends of sufferers) of inflammatory bowel disease Crohns and ulcerative colitis. The IBD patients recently received a letter from Janssen Inc., which makes one of the miracle drugs of our time, Remicade.

Remicade is a monoclonal antibody a mab, as your pharmacist would say to another pharmacist. This means its an ultra-complicated lab-designed molecule that is somewhat like a prosthesis for your immune system. Before Remicade, the old approach to IBD disorders was to wait until they became disabling or life-threatening, as opposed to just colossally inconvenient and painful, and then deluge them with steroids. With Remicade, many patients with severe IBD can live in remission indefinitely.

This is not cheap, which is why vis prescribed to only a fraction of those with IBD. Remicade is nonetheless the single largest prescription drug expense, by far, that the Alberta government has. In the year ending March 31, 2018, Alberta Health spent more than $80 million dispensing the drug to 2,535 patients.

You might expect that this situation would attract the attention of capitalism, and countless drug companies are indeed developing biosimilar alternatives to Remicade. Health Canada, acting more slowly than other developed countries, has approved a couple.

Biosimilars are drugs that have the same overall molecular structure as some reference drug and have been shown in the laboratory to target the same receptors in the body. Simple molecules dont attract imitators like these, but the mabs are (on the molecular scale) huge, intricate wads whose activity may not be perfectly understandable. Mabs were introduced because in-vitro laboratory drug creation using computer models and biological first principles got a lot better around the turn of the century. Biosimilar rivals, marketable for lower cost, exist for the same reason.

Remicade is the single largest prescription drug expense that the Alberta government has

So government drug plans have been itching to move patients onto cheaper biosimilars, or perhaps force discounts on Remicade. In British Columbia, the government a New Democratic government is currently in the process of switching everybody to biosimilars by fiat, with exceptional Special Authority approval (!) required for patients who prefer the name brand. Janssen wrote to Remicade patients when it learned that Alberta and Ontario were also eyeing their big Remicade bills.

Alberta hasnt decided whether to follow B.C.s guillotine approach. Theres a serious, evolving discussion about the evidence base for the biosimilars. It is fairly well established that patients can switch to one of the best biosimilars without risk, and that the biosimilars behave like the name brand within the immune system as far as any testing can show. But the empirical studies have been short in duration, and no one has been able to check what happens if doctors engage in multiple switching among biosimilar molecules.

This should not be a partisan conversation, but, well, if you are protesting on the legislature steps, your handmade sign is not going to read The magnitude of the nocebo effect is contested! The Sunday protest in Edmonton was led by a Crohns patient, Nick Arrand, who told the Journals Jonny Wakefield, The government should have no right to tell you what medications to take.

The story adds that Mr. Arrand is on his wifes insurance, so the government is not, in fact, telling him what medications to take. His insurer, one supposes, might eventually have something to say about it. Should he picket that companys headquarters if this happens? Or should he go bother Janssen about the price of Remicade? What would Bernie Sanders do?

For patients on government health plans, the government does decide what to pay for (if there were a punctuation mark meaning duh, it would go here), and it has no choice but to take cost into account, as an NDP-led government in idyllic B.C. has. This did not discourage MLA Shepherd from joining the Edmonton protest to denounce barbarous right-wing Alberta-government cost-chopping that might or might not happen. And which is, at root, a negotiation between Albertas public treasury and a constellation of drug manufacturers.

What would Bernie Sanders do?

Shepherd accused the Conservatives of intending to try to force their way into the doctor-patient relationship and force these individuals to switch onto new, unproven biosimilars. This is a curious departure from the official position of Crohns and Colitis Canada, which is that Biosimilars are a safe and effective treatment for people with Crohns disease and ulcerative colitis.

The charity, which receives funding from Janssen and organized the pro-Remicade demonstration, expresses concerns with non-medical switching of drugs for cost reasons alone. But it also concedes, quite explicitly, that in these here social democracies, none of us exists in a consecrated doctor-patient relationship without the presence of a third party footing the bill. Even when Bill Gates gets sick, he doesnt ask for the most expensive drug on principle.

Humans and autoimmune diseases continue to evolve together – Medical News Today

Saturday, November 30th, 2019

The ability to fight disease is a driving force in human survival. Inflammation has emerged as a key weapon in this process. As pathogens change and evolve, the immune system adapts to keep up.

However, to what extent might such evolutionary adaptations also give rise to autoimmune conditions such as lupus and Crohn's disease?

This was a central question in a recent Trends in Immunology review by two scientists from Radboud University, in Nijmegen, Netherlands.

To address the issue, first author Jorge Domnguez-Andrs, a postdoctoral researcher in molecular life science, and senior author Prof. Mihai G. Netea, chair of experimental internal medicine, examined studies in the fields of virology, genetics, microbiology, and immunology.

They focused on people of African or Eurasian descent and how their ancestral origins may have influenced their risk of autoimmune diseases.

Of particular interest was how common pathogens in different communities related to changes in people's DNA, particularly when this involved inflammation.

The team found that the genetic changes made it harder for pathogen infections to take hold.

Over time, however, it seems that inflammation-related diseases, such as inflammatory bowel disease, Crohn's disease, and lupus, have emerged alongside improvements in immune defenses.

The findings also suggest that the human immune system continues to evolve and adapt to changes in environment and lifestyle.

"There seems to be a balance," says Domnguez-Andrs.

"Humans evolve to build defenses against diseases," he continues, "but we are not able to stop disease from happening, so the benefit we obtain on one hand also makes us more sensitive to new diseases on the other hand."

He observes that autoimmune diseases in today's humans tend to emerge later in life. These would not have caused health problems for our ancestors because their lives were much shorter.

"Now that we live so much longer," he explains, "we can see the consequences of infections that happened to our ancestors."

One of the examples that Domnguez-Andrs and Netea cover in detail in their review is malaria.

"Among various infectious diseases," they write, "malaria has exerted the highest evolutionary pressure on the communities across the African continent."

Malaria is a mosquito-borne disease that makes people very ill with flu-like symptoms, such as chills and a high fever.

While there has been much progress in the fight to control and eliminate the potentially fatal disease, it continues to threaten nearly half of the world's population, according to the World Health Organization (WHO).

The cause of malaria is parasites belonging to the species Plasmodium. These parasites spread to humans through the bites of infected female Anopheles mosquitoes.

Domnguez-Andrs and Netea note that Plasmodium has been infecting people in Africa for millions of years. During that period, the immune systems of those human populations have evolved stronger resistance to infection by increasing inflammation.

However, the downside of increasing inflammation to withstand infectious disease is that it favors health problems that tend to occur later in life.

Modern humans of African descent are more prone to developing such conditions, which include atherosclerosis and other cardiovascular diseases.

Another example of how ancestral changes in DNA leave imprints in the immune systems of modern humans is the interbreeding of early Eurasians with Neanderthals.

Modern humans whose genomes harbor remnants of Neanderthal DNA have immune systems that are better able to withstand staph infections and HIV-1. However, they are also more prone to asthma, hay fever, and other allergies.

Improvements in technology are making it more possible to find the downsides that can accompany disease-fighting adaptations.

Next generation sequencing, for example, is allowing scientists to delve more deeply into what happens at the DNA level between pathogens and the organisms that they infect.

Not only is new technology getting better at revealing genetic changes that occurred in our ancestors, but it is also showing that the human immune system continues to evolve and adapt.

In Africa, there are still tribes that hunt for food as their ancestors did. Thanks to new tools, scientists can see how the gut bacteria of these tribes are more diverse than those of, for example, contemporary African American people, who buy food in stores.

Other changes that have had an effect on DNA are the improvements in hygiene that have occurred in recent centuries. These have reduced exposure to pathogens and the diversity of gut bacteria.

"This reduced microbiota diversity in Western societies," the authors observe, "has been associated with a higher incidence of the so-called 'diseases of civilization,' such as cardiovascular diseases, diabetes, obesity, and autoimmune disorders, which are very unusual in hunter-gatherer societies, compared with communities living a Western-type lifestyle."

Domnguez-Andrs and Netea are extending their research to populations whose ancestry is other than African or Eurasian.

"Today, we are suffering or benefiting from defenses built into our DNA by our ancestors' immune systems fighting off infections or growing accustomed to new lifestyles."

Who needs the flu vaccine? | Valley Health – Mat-Su Valley Frontiersman

Saturday, November 30th, 2019

The burden of flu on our society is tremendous The Centers for Disease Control and Prevention (CDC) estimates that influenza has resulted in between 9.3 million 49.0 million illnesses, between 140,000 960,000 hospitalizations and between 12,000 79,000 deaths annually since 2010.

The CDC recommends that everyone 6 months of age and older should get an influenza (flu) vaccine every year, with rare exceptions.

The primary reason to not get the flu vaccine is an allergy to one of the components of the vaccine (for example gelatin) or an allergy to eggs (because the virus is raised in eggs). If you have had the rare neurologic condition called Guillian-Barre Syndrome, you also should not get the vaccine.

The standard flu shot is given into the muscle of the arm and this is the form recommended for most persons. There is an intradermal form that is injected into the skin using a much smaller needle. This form can be given to persons age 18 to 64 years.

Persons over age 65 are recommended to get the high dose form of the vaccine Fluzone high dose. This form of the vaccine contains four times as much antigen (the part of the vaccine that causes the body to form antibodies against the flu virus) as the standard vaccine. The higher dose is intended to give older persons better protection by causing a better immune response. Vaccines are also available that contain an adjuvant. An adjuvant is an ingredient that helps to cause a greater immune response. This form of the vaccine is recommended for persons age 65 and older.

A nasal form of the vaccine is also available. This form of the vaccine provides protection against two forms of influenza A and two forms of influenza B. It may be given to persons age 2 through 49 years. This form of the vaccine contains a weakened but living form of the viruses. It is not recommended for pregnant women, persons with weakened immune systems and young children with asthma or who are taking aspirin. Ask your doctor if you can use this form of the vaccine.

Success! An email has been sent to with a link to confirm list signup.

Error! There was an error processing your request.

The flu vaccine is especially important for persons at high risk of complications from the flu. High risk groups include: persons over the age of 65 years; persons with diabetes; persons with asthma or chronic lung diseases (chronic obstructive pulmonary disease and cystic fibrosis); persons with chronic kidney or liver disease; persons with weakened immune systems (those with HIV or AIDS). Certain cancers (especially leukemia), persons receiving chemotherapy or radiation therapy for cancer and persons on drugs that weaken the immune system are also at increased risk. Again it is important to ask your healthcare provider about your risk and whether it is safe for you to get the vaccine.

If despite getting the vaccine you get the flu, avoid contact with other persons (as much as possible except to seek medical help) until your fever has been gone for 24 hours.

Dr. Samuel Abbate is a local physician practicing in Wasilla.

HIV, my baby and me: ‘I was 17 years old when I was diagnosed’ – BBC News

Saturday, November 30th, 2019

Media playback is unsupported on your device

"People will judge me, but I'd just say walk a mile in my shoes."

Jane, not her real name, was 17 years old when she was diagnosed with HIV.

"I'd only slept with one person when I got HIV, I know people will hear that and think it's a sob story, but it's the truth," she told BBC News NI.

When Jane was diagnosed she was one of the youngest women in Northern Ireland known to have the virus.

HIV is a virus which, over time, damages the human immune system leading to illness and infection.

There are 1,130 people receiving treatment for HIV in Northern Ireland. It is not known how many more people are living with the virus undiagnosed.

The charity Positive Life says there is still a myth that it's a "gay man's disease".

Figures show that in Northern Ireland almost 40% of those living with HIV contracted the virus through heterosexual contact and more than 200 women have been diagnosed HIV-positive.

"When I was first diagnosed, I started to research stuff online and I watched some films where people had HIV and it really scared me," said Jane.

"It showed people getting really sick and their skin started to get really bad and it showed people dying. I thought: 'Is this what is going to happen to me?'"

In 2018, 96,142 people were receiving HIV-related care across the UK.

HIV - Human Immunodeficiency Virus - is a virus which, over time, damages the human immune system.

Media playback is unsupported on your device

The immune system is the body's defence against infectious organisms and infections. Problems with the immune system can lead to illness and infection.

Aids - Acquired Immunodeficiency Syndrome - is the result of damage to the immune system caused by HIV.

Jane's mother admits she initially struggled with her daughter's diagnosis.

"At the start, I had all the stereotypes and stigmas in my head that you could think of.

"I just thought: 'This can't be happening to her.' And how unfair it was to be happening to someone her age, to someone who wasn't promiscuous.

"But I know now it doesn't matter if you're promiscuous or not, it only takes one time, and the rest of your life can be changed forever."

Those living with HIV have the same life expectancy as those without the condition, thanks to antiviral treatments used since 1996.

Following her diagnosis, Jane began medication which suppressed the virus and made HIV levels virtually undetectable in her system.

This meant it couldn't be transmitted - even through sexual activity.

Since then, Jane has given birth to a baby boy.

"During my pregnancy I was on three different types of tablets to make sure that my baby wouldn't get HIV," she said.

"I have a wee boy now, but the medication worked, because he doesn't have HIV.

"HIV isn't going to stop me being there for my son. I still have a roof over my head, I have family support."

There were 4,500 pregnancies to HIV-positive women in the UK and Ireland between 2015 and 2018.

Of those, less than 20 have transmitted the virus to their children, either through pregnancy, birth or breastfeeding.

There are still many misconceptions about HIV, according to the charity Positive Life.

"People will still ask if you can catch HIV off a toilet seat or by using the cutlery of people who are HIV-positive - there is still a lot of negative language around it, " said Positive Life's Jacquie Richardson.

"The three biggest myths we hear are that it's a gay man's disease, that it's contracted as a result of a promiscuous lifestyle and that you'll die if you've a diagnosis.

"We're working very hard to counter those myths."

GETTY

in Northern Ireland

There is still a lot of work to be done to educate the public about women and HIV, said Ms Richardson.

"Many people wouldn't even consider that if a woman is HIV-positive she can now, through early diagnosis and medication, have a baby that doesn't have HIV, and that's a powerful message," she said.

"That's why stories like Jane's are so important in challenging all the myths and misconceptions.

"This is a young woman from Northern Ireland, engaging in her first sexual activity, in a heterosexual relationship and she contracts HIV - all of the stereotypes and assumptions people associate with HIV are turned on its head by this very powerful story."

Jane's mother believes more should be done to educate young people about the risks of contracting HIV.

"HIV is still such a taboo subject," she said. "My daughter's story shows it's possible for a young girl in her prime to get HIV and I believe more could be done around sexual education in schools."

She added: "Because of organisations like Positive Life, we're more informed now. We know her HIV can't be cured, but it can be treated.

"But that also means she is going to be on very strong medication for the rest of her life and that does worry me."

Jane is determined not to be defined by being HIV-positive.

"I can't change the past, but what I would say to anyone, if you're sexually active, whether it's your first time or not, just be safe," she said.

"I have to live with the fact that I'm HIV-positive, but I won't let it ruin my life."

Boston docs: Early treatment helps African babies with HIV – Boston Herald

Saturday, November 30th, 2019

Early treatment with antiretroviral therapy, an HIV drug not usually administered right after birth, can help babies born with the virus that infects 300-500 infants in sub-Saharan Africa every day, Boston doctors have determined.

We find that ART initiation within hours after birth is doable and translates into multiple benefits for the infants lower frequencies of reservoir cells and improved immune responses, said corresponding author of the study published in Science Translational Medicine, Dr. Mathias Lichterfeld, associate infectious disease physician at Brigham and Womens Hospital.

Antiretroviral therapy is a combination of at least three drugs that are highly effective at suppressing HIV and stopping its progression.

The therapy is not typically given to babies right after birth, but new research shows the number of infected cells in HIV-positive babies given the treatment within days or hours of birth was extremely small compared to infected infants who started treatment later.

What excites me most about this work is that making a comparatively small change in the timing of treatment may have a large impact on long-term treatment outcomes, said Lichterfeld.

The study was conducted in two major maternity hospitals in the Francistown and Gaborone regions of Botswana, a country with the third-highest HIV-1 prevalence in the world.

HIV progresses much faster in infants than in adults because of their weaker immune systems.

Infants enrolled in the study began treatment right after birth and researchers compared their results to those of infants not in the study who received the drug within a median of four months after birth. The babies were then followed for two years with blood sampling at regular intervals.

The study was small and focused on 10 HIV-positive babies that were enrolled. A total of 40 infants have been recruited into the study and samples from the remaining babies are now being analyzed.

A new clinical trial has also been started with some of the same infants in which a different treatment is being evaluated.

As of June, an estimated 24.5 million people globally were accessing antiretroviral therapy, according to the Joint United Nations Program on HIV/AIDS.

Antiretroviral therapy does not cure HIV, but helps infected patients live longer and healthier lives. It also reduces the risk of HIV transmission by lessening the amount of the virus in the body, which in turn gives the immune system a chance to recover.

Nearly 38 million people across the globe were living with HIV as of last year and about 8 million didnt know they were infected.

Longstanding research has found that exercise that increases our cardiovascular activity brings a number of health benefits, including lowered blood pressure; improved cardiovascular health; strengthening of the immune system; regulation of weight; and moderation of blood sugar. Interestingly, it appears that vigorous aerobic activity (maintaining more than 60% of aerobic capacity) brings greater cardiovascular health benefit than moderate activity. Exercise therapy has been found to improve a measure called heart rate variability, which is associated with greater levels of psychological well-being and resilience in the face of stress. One strand of research finds that aerobic exercise conducted in a mindful state (i.e., with enhanced self-awareness, such as yoga and Feldenkrais) brings greater mood benefits than routine vigorous or moderate cardio workouts. Many of the activities we associate with self-development, from counseling and psychotherapy to meditation, are pursued in a state of reduced physical activity and enhanced self-awareness. Might it be the case that vigorous aerobic activity is an equally promising path toward emotional well-being and a positive psychology?

According to the National Institutes of Healths National Center for Complementary and Integrative Health, yoga, a discipline of meditative movement is associated with such benefits as stress relief, pain reduction, and emotional well-being. There is also evidence that yoga also improves the aforementioned heart rate variability and lessens symptoms of depression. In an excellent review article, Julia Belluz notes the limitations of much of the research on the benefits of yoga, but cites fascinating evidence that yoga may be uniquely helpful in reducing inflammation in the body. Similar amounts of time spent in yoga and general physical activity yield greater inflammation benefit for the yoga participants, presumably because of the added components of mindfulness.

In a review of brief approaches to psychotherapy that I conducted with two colleagues at SUNY Upstate Medical University in Syracuse, an important conclusion was that these methods are effective to the degree that they generate novel, constructive experiences for clients. Such corrective emotional experiences deal with maladaptive patterns of emotion and behavior by activating more constructive ones. Thus, for instance, when a client retreats from a therapist out of fear of rejection, the therapist may encourage engagement and provide an active experience of acceptance and understanding. Such emotional experiences are readily internalized, helping people build new modes of construing and doing. This is the basis for many behavioral and cognitive therapies, where we learn to face and challenge our patterns of anxiety, negative thinking, and depression in emotionally impactful ways.

The unexpected benefits of aerobic exercise, yoga, and similar disciplines may arise from their ability to provide similar corrective emotional experiences, albeit outside of a therapeutic relationship. Through vigorous exercise, we directly challenge our limits and experience ourselves as efficacious and achieving. Through mindful movement, we experience enhanced levels of self-control and mastery. A great example of this occurs among the money managers and traders I work with, who make active use of meditation to deal with the stresses of markets and their inherent risks and uncertainty. In the midst of threat, direct experiences of calm and focus promote a unique experience of the self as being in control, facilitating sound decision-making. Exercise, like coaching, counseling, and psychotherapy, is a vehicle for generating fresh experiences of the self, reinforcing and expanding our strengths.

In recent articles, Ive explored the psychological benefits of living a purposeful life and the importance of emotionally connecting with a positive vision of our future selves. All of these can be paths toward emotional resilience, increased mindfulness, and an enhanced capacity to pursue life goals. In a recent interview, Steven Goldstein and Mark Randall explore the mindfulness associated with special forces operations, highlighting the idea of mindfitness. A well-constructed program of exercise, expanding our abilities to extend our limits and sustain self-control and efficacy, provides a uniquely effective form of self-developmenta promising therapy for the mentally well and program for mindfitness.

Hey, Brady’s healthy; Pats’ Hightower, Wynn return to practice – The Union Leader

Saturday, November 30th, 2019

FOXBOROUGH, Mass. In a Patriots locker room thats battling widespread illness recently and plenty of injuries during the season, quarterback Tom Brady said hes managed to stay unaffected.

Im a pretty healthy guy. Cant avoid it all the time. I try to for the most part. I keep my immune system nice and strong if possible, he said Friday as the Patriots prepare for Sunday nights game at Houston.

His immune system might be able to stop the flu, but it cant hold off opposing defenders.

I wouldnt be in the self-preservation business if I was trying to be a football player, said Brady, who is expected to play Sunday. Youre going to get hit. You just have to understand thats part of the game. You have to understand when they blitz, you dont have as much time to throw. So you have to throw the ball a little quicker. ... Taking hits is part of it. My whole objective is standing there and trying to get the ball to someone who can do something with it.

He said throwing the ball away is more about protecting a drive and protecting possession than protecting himself.

Im throwing it away because I dont want to take a sack, Brady said. I think negative plays actually have a big impact on the game. Turnovers and negative plays I think really keep you from winning games. So, if you can drop-back pass, because Im not really a scrambler ... But, if Im going to hold it back there, then usually good things arent going to happen. So, I try to throw the ball away to save plays and live for the next down.

Pats getting healthier

All that Vitamin C is finally paying off for the Patriots. After a flu bug ripped through their locker room eight players missed Wednesdays practice with illness they were almost at full strength for Fridays walkthrough.

Kyle Van Noy was a new absence, and Ryan Izzo has been out all week with the flu. One of the leagues best linebackers, Van Noy will be sorely missed if he isnt good to go by Sunday.

Donta Hightower, Isaiah Wynn and JoeJuan Williams all returned. All three players were healthy enough for Fridays walkthrough. The biggest takeaway from Friday: The Patriots seem to have weathered the worst of their flu bug.

Players listened to an assortment of college football fight songs on Friday. With rivalry games all weekend, the Patriots were listening to band songs. Tom Brady pumped his fist when Michigans The Victors began.

Gut microbes alter characteristics of norovirus infection – Washington University School of Medicine in St. Louis

Saturday, November 30th, 2019

Visit the News Hub

Findings, in mice, could guide research into future therapies

A new study led by Washington University School of Medicine in St. Louis reveals details about how gut microbes interact with norovirus infection in the mouse gut. The research opens up new ways of thinking about potential therapies for this intestinal infection. Shown are Norovirus particles.

The highly contagious norovirus causes diarrhea and vomiting and is notorious for spreading rapidly through densely populated spaces, such as cruise ships, nursing homes, schools and day care centers. Each year, it is responsible for some 200,000 deaths, mostly in the developing world. There are no treatments for this intestinal virus, often incorrectly referred to as stomach flu.

Now, a new study led by scientists at Washington University School of Medicine in St. Louis has shown that gut microbes can tamp down or boost the severity of norovirus infection based on where along the intestine the virus takes hold.

The study, published Nov. 25 in the journal Nature Microbiology, suggests new routes to possible therapies for norovirus infection. Collaborators included researchers at the University of Florida, the University of Michigan and Yale University Medical School.

There are currently no treatments for norovirus, which is very easily spread through fecal-oral transmission, said co-senior author Megan T. Baldridge, MD, PhD, an assistant professor of medicine at Washington University. Norovirus is especially dangerous in young children, older adults and people with compromised immune systems. We are trying to understand how the gut microbes interact with norovirus in an effort to pursue new therapeutic strategies.

In these mouse studies, the researchers found that normal gut bacteria boosted the severity of viral infection in the lower small intestine, which is in line with past work in the field. But simultaneously, normal gut bacteria blocked or inhibited viral infection in the upper small intestine. In other words, gut microbes can have totally opposite effects on norovirus infection depending on the infections location along the length of the gut.

These results were a huge surprise to us, Baldridge said. We showed that different parts of the intestine can show dramatically different responses to this type of infection. Our research reveals that we cant view the gut as a homogeneous tube that responds to infection in a uniform way.

Baldridge and her colleagues found that the difference in response was driven by bile acids, which are mainly known for their roles in digestion.

Bile acids are powerfully regulated by bacteria all along the gut, Baldridge said. But there had not been a realization that these bile acids could prime the gut to mount an immune response against intestinal viruses.

In the new study, the researchers showed that bile acids in the upper small intestine but not the lower stimulated the immune system to respond to the infection. The researchers determined that bile acids in that region of the gut triggered a molecule called interferon III one of the bodys key antiviral defenses in the intestine to become activated.

Baldridge noted that this complexity of interactions between gut microbes and bile acids could explain some of the variability seen in norovirus infections. Some people become extremely ill with this virus; others develop no symptoms at all.

The different ways people respond to viral infections could be related to their individual gut microbial community, Baldridge said. The severity of an infection could be tied to where exactly along the gut you get an infection, and that might be controlled by your individual microbiome. Subtle differences along the intestine could end up having dramatic effects on how the gut perceives the virus and responds to it.

Baldridge also said that this changes how researchers might think about strategies to protect against or treat norovirus infection. They might seek ways to expand the immune interferon signaling that they observed only in the upper small intestine such that it extends along the entire length of the gut, for example.

She and her colleagues are planning more studies to help investigate whether there may be ways to manipulate the gut environment through bile acids or the microbiome itself to stimulate the immune system in ways that could shut down norovirus infection.

Unlock the Mysteries of Your Gut Microbiome With Viome’s Gut Intelligence Test – Futurism

Saturday, November 30th, 2019

Despite the fact that we live in a highly advanced technological society, when it comes to important things like health and nutrition, a lot of people are still willing to take most of their advice from bloggers and social media influencers who have little to no scientific training. This is especially true when it comes to gut health and the gut microbiome. Luckily, the scientists and researchers at Viome are on a mission to change all that.

Over the past few decades, the scientific community has made some incredible advancements in our understanding of the human gut microbiome. We now know, for example, that the complex community of bacteria and other microorganisms that live in our digestive tract affects almost every system in the body, including the digestive system, immune system, and cardiovascular system. There have also been studies that specifically link gut health to a number of human diseases and conditions, such as diabetes, obesity, irritable bowel syndrome, and colon cancer. But how do we put this information to use?

A lot of people have been led to believe that you can ward off all these illnesses and conditions simply by eating a bunch of exotic fermented foods you saw on Instagram. Unfortunately, thats like throwing a bunch of random ingredients into a pot and hoping they turn into your favorite soup. The stuff you put into the pot might be delicious, but different soups call for different ingredients.

Similarly, one of the most important things weve learned about the human gut microbiome in recent years is that everyone is totally unique. Thus, whats good for one gut isnt necessarily whats good for the next. Thats why, if you want to get serious about gut health, you need to start by taking the Gut Intelligence Test by Viome.

At Viome, their goal is to take the guesswork out of building a healthy gut. To do that, theyve created the worlds most scientifically advanced microbiome test.

A microbiome test is like a DNA test, only instead of mapping out genes, it maps out the specific strains of bacteria and other microorganisms that live in your digestive tract. What makes Viomes test superior to any others currently available is its proprietary microbe identification technology and its advanced analytics engine.

Viome is the only company in the world that uses advanced metatranscriptomic sequencing technology, which was originally developed at the Los Alamos National Laboratory for national security purposes. This technology helps them identify and quantify all the strains and species of microorganisms in your gut and determine exactly how active they all are. Then Viome runs all this data through an advanced AI algorithm called VIE, which uses a massive and continually growing database of information to come up with personalized nutrition recommendations.

When your gut microbiome is out of balance, your body doesnt absorb nutrients the way it should. It can also produce toxins that cause inflammation, which scientists now realize is at the root of almost every chronic disease. The foods Viome recommends are intended to stimulate your microbiome so that it maximizes the production of healthy nutrients and minimizes the production of toxins.

With the Gut Intelligence Test by Viome, you dont have to go to a cold sterile lab to be poked and prodded. The entire process is pain-free and takes place in the comfort of your own home. Once you place your order, Viome will send you an easy to use, non-invasive at-home kit to collect your sample. Then you simply return your sample using the postage-paid box provided, and Viome will process it and send you the results.

With Viome, all test results and dietary recommendations come with detailed explanations, and all of them are conveniently delivered straight to your phone via the Viome mobile app, which makes them incredibly easy to put into action.

The default reports and recommendations are aimed at increasing microorganism species associated with overall wellness and decreasing species typically associated with poor health. However, you can also customize your recommendations based on specific health and wellness goals, including weight loss, better sleep, or increased mental clarity.

Viome does not promise that everyone who takes their test will see the same level of results because not all health and wellness issues can be fixed by diet alone. What Viome does promise is a better, more scientific understanding of whats going on in your body.

Right now, Viomes Gut Intelligence Test is 62 percent off the regular price. If youre tired at guessing about matters related to your health and wellness, order your test from Viome today.

Hilary Duff made sure to spend some quality family time as she celebrated Thanksgiving and it looks like one family member was enjoying eating something that is not considered edible.

Her youngest daughter, Banks, 13 months, thought it was funny to eat some dirt rather than turkey which is what most Americans eat at the dinner table for Thanksgiving.

Taking to Instagram, Hilary shared an adorable picture of her alongside partner Matthew Koma, and her oldest kid, seven-year-old Luca and of course, Banks, with dirt all over her face.

HAPPY THANKSGIVING, she wrote. Banks just ate dirt.

As you do.

Banks you ate better than me today!!!! one fan wrote in the comments.

All that good food and you eat dirt, Banks, LOL, another added.

Banks is my spirit animal, another fan commented.

And one fan actually thought that the dirt on Banks face was a speck of dirt on their phone screen.

I kept trying to wipe my screen thinking it had something on it, they wrote.

But then I read your caption, Banks is building up her immune system.

Hilary is no stranger to sharing the love and appreciation she has for her kids on social media and more recently, she found herself struggling to help Luca with his school homework as she claimed she left real school in the third grade.

Taking to Instagram, she shared a selfie of her and Luca at the table while in the middle of hitting the books.

This guy with his spirit and kindness. Homework is already no joke in 2nd grade, she wrote.

I stopped going to real school in 3rd grade so Im actually doomedI am left scratching my head all the time looking at his homework and Im terrified for next year!

In the meantime, the 32-year-old has been currently busy filming for the upcoming Lizzie McGuire revival and her co-star Adam Lamberg, who played David Gordo Gordin, will also be making a return.
