Myth Busting ‘Blind As A Bat’ And ‘Memory Of A Goldfish’ – NPR

January 11th, 2020 5:44 pm

People in the United States say someone is "blind as a bat" to mean that person has poor vision. James Hager/Robert Harding World Imagery/Getty Images hide caption

People in the United States say someone is "blind as a bat" to mean that person has poor vision.

Animals' abilities are often used to describe people's personality traits or attributes. If you're stubborn, you might be called "pig-headed." Is your room at home a mess? A parent might call it a "pigsty." If you're being rude, someone might call you a "jacka**" you get the drift.

But what validity is there to these statements?

That's the question we're tackling here at Short Wave as part of a series called "Animal Slander."

We're starting with the phrases "blind as a bat" and "memory of a goldfish" because they are problematic, for multiple reasons. For one, the phrases are often used in a derogatory manner and it is not cool to make fun of people based on their physical or mental abilities.

And second, the phrases aren't even true.

1. Blind as a bat: a compliment of your ability to see ultraviolet.

People in the U.S. use the phrase "blind as a bat" to rib someone for not being able to see well.

We put this phrase to Johan Eklf, who wrote his Ph.D. thesis on bat vision at Gothenburg University in Sweden. According to Eklf, there are over 1,300 species of bats and none is truly blind.

Different species rely on their eyesight to varying degrees often in combination with their sense of smell and echolocation. For example, some Emballonuridae bats that rely heavily on echolocation can still see centimeter-sized objects from about a meter away.

That being said, Eklf notes that, "They don't need their eyes to look up close. They need their eyes to figure out where they are, look at the horizon, see the trees and skyline."

Fruits bats are able to see even better than this, Eklf says. In fact, most fruit bats don't use echolocation at all. They have big eyes that allow them to primarily rely on vision and sense of smell to find fruit.

There is a myth that goldfish have a memory of only three seconds. Classen Rafael/EyeEm/Getty Images hide caption

There is a myth that goldfish have a memory of only three seconds.

2. Memory of a goldfish? Maybe you're not so forgetful after all.

The myth is that a goldfish's memory lasts about three seconds. This has been repeatedly debunked.

Ryan Wong, an assistant professor of biology at The University of Nebraska Omaha, helped us out with this one. He researches fish behavior, learning and memory.

"There are definitely lots of different studies out there and many different species of fish that show that fish have really complex learning abilities and also have the ability to remember this information for long periods of time," Wong says.

He says goldfishes' memory can last for weeks.

In one experiment, goldfish were conditioned to push a lever at a certain time of day to obtain food. That means the fish had to remember both that pushing the lever meant food and in which window of time this food would be accessible.

Some studies have also shown that goldfish are even have the kind of memory that allows them to solve mazes.

So, the verdict on the bats and the goldfish is...

Slander.

Ellas Gift: Childs memory lives on through gifts to others – The Augusta Chronicle

January 10th, 2020 9:55 pm

One of the things Jody Bumgardner had in common with her 10-year-old daughter, Ella, was shyness.

She was super shy. At 10, she still wanted me to walk her to her class, said Bumgardner, who will put aside her own shyness on Jan. 18 to speak at First Baptist Church of North Augustas Mix and Mingle With a Mission event at 10 a.m. The event is sponsored by the churchs womens ministry.

The last time Bumgardner walked Ella to her Awana class was Wednesday, Oct. 5, 2016. Unbeknownst to her family, Ella had been born with an arteriovenous malformation (AVM), and on that night while still at church, her brain began to bleed.

Medical professionals attending First Baptist recommended Ella be taken to the hospital after she exhibited a myriad of symptoms including severe pain, blindness and difficulty breathing. They called an ambulance that took her to the Childrens Hospital of Georgia, where she died two days later.

Bumgardner will share Ellas story at the Jan. 18 meeting as well as speak about a program her family has started called Ellas Gift, which provides small gifts for children at the hospital.

We wanted to think of ways to keep her memory alive and be able to help people, she said.

They began taking the gifts to the hospital not long after Ellas death.

Small coloring and activity books, crayons, stickers, a small New Testament and other items are placed into the green bags embroidered with Ellas name on them. Green was Ellas favorite color. The bags also come with a card with Ellas photo and her story on the back.

They provide some distraction from a scary test or keep them occupied while in the hospital, Bumgardner said.

Theyve heard that children now look forward to the items, and they try to keep the hospital stocked with them, she said.

She will be taking donations for Ellas Gift at the Jan. 18 meeting.

Bumgardner said it brings her joy knowing Ella still makes a difference even though shes no longer alive.

She would be so embarrassed at all the attention, she said. Im so thankful God has used her life.

Not only will she talk about Ella on Jan. 18, but Bumgardner will share pieces of her own story and how her faith has helped her through.

(Gods) been there every step of the way, she said.

She said shes found comfort in scripture including ones such as Philippians 4:13, which says in the King James version, I can do all things through Christ which strengtheneth me.

Its a verse she walks out on a daily basis, she said.

I couldnt do this if it wasnt for him, she said.

She said there are some days when shed rather stay home and cry, but she remembers that verse and it helps her through the day. She knows that her life helps other people, and that means a lot to her as well.

The event is free and open to area women. Registration is available online at http://www.csrachurch.org. Click on Events, then Mix & Mingle. The deadline to register is Jan. 12.

In focus: the best books to reveal your blind spots – The Guardian

January 10th, 2020 9:55 pm

They say theres a German word for everything. My favourite is Lebenswelt, an idea described by the Austrian philosopher Alfred Schtz as that province of reality which the wide-awake and normal adult simply takes for granted as common sense. Probing beyond this is the hard work of authors: they remove our blinkers, while revealing deeper layers of reality. That is, they teach us how to see, instead of merely look.

Take a simple patch of dirt. Most of us wouldnt look twice. But David Haskell spent a year nose-deep in leaf litter examining a single square metre of old-growth forest in Tennessee. In The Forest Unseen he documents the marvellous profusion of life, and all the miniature commuters from snails and salamanders to coyote pups and woodpeckers that cross this small parcel of land, or call it their home. The result is an almost magical look at the interconnectedness of the natural world, and the invisible ties that bind us together.

In the urban jungle, we are bound by different threads: unsleeping algorithms that trawl the internet finding patterns that are invisible to human eyes. In Weapons of Math Destruction, Cathy ONeil lays bare the maths, rules and data that increasingly shape our everyday lives. Models, she writes, are opinions that are embedded in mathematics. She charts the unchecked growth of these models, and how they are coming to define school admissions, bank loans, mortgages and health insurance even the ways our societies are policed. Learning how to read between the lines (of code) becomes crucial if we are to unlock their hidden biases.

In Wilful Blindness, Margaret Heffernan asks us to consider why we sometimes think ignorance is bliss

Skinny Legs and All by Tom Robbins is the only work of fiction on this list. On the surface, the story is about a pilgrimage to Jerusalem by a cast of oddball characters, including talking inanimate objects. Robbins deftly weaves the separate narratives together in a climactic big reveal; a showdown where the audience must choose between watching the Super Bowl or Salomes Dance of the Seven Veils a dance that reveals, with each veil discarded, a grand illusion held by humanity.

There are illusions, and then there are the things that we refuse to see. In Wilful Blindness, Margaret Heffernan asks us to consider why we sometimes think ignorance is bliss. Drawing on insights from whistleblowers, business leaders, criminals, psychologists and neurologists, she reveals that often we deliberately put on blinkers to avoid conflict, feel safe, reduce anxiety and protect prestige. Perhaps even more dangerous are the ways in which companies and corporations can become structurally blind; not because their leaders dont want to see, but because their sights are so myopically set on being competitive.

Last in my list is a blind spot that can be revealed through photography. Jo-Anne McArthurs haunting book We Animals documents the day-to-day conditions of animals hidden away in medical testing labs, industrial farms, circuses, aquariums and markets. While in our minds eye we picture animals out in the wilderness or grazing in meadows, McArthur brings an empathetic lens to the grim reality mostly unchallenged of millions of lives spent in captivity.

Short-sightedness in kids was rising long before they took to the screens – ABC News

January 10th, 2020 9:55 pm

Updated January 07, 2020 09:22:18

The number of people with myopia, aka short-sightedness (difficulty seeing objects in the distance), has increased dramatically in recent years in various regions of the world.

For example, in many cities in China, more than 90 per cent of university students are living with myopia. In pure numbers, this is one of the largest epidemics humanity has ever seen, far greater than the obesity epidemic.

The myopia boom was first noted in the 1980s in the cities of East Asian countries such as Korea, Taiwan and Singapore. The cities of China followed soon afterwards, and a similar trend is being noted in Europe.

For most people, myopia is merely an inconvenience requiring correction with glasses, contact lenses or refractive surgery.

Notably, myopia is associated with an increased risk of blindness from retinal detachment, glaucoma and myopic macular degeneration. Risk of blindness increased with worsening severity of myopia and this is a major public health concern.

Researchers and parents of children developing myopia have looked for explanations and the latest "suspect" is the use of personal electronic devices.

But the myopia epidemic in Asia preceded the release of smartphones by many years (the first iPhone was released in 2007).

New technologies televisions in the 1960s, computers in the 1980s, laptops in the 1990s, and currently smartphones and tablets have all been blamed for causing myopia.

As far back as the 1600s, the German astronomer Johannes Kepler, who first identified concave lenses could correct myopia, is said to have attributed his short-sightedness to all his years of "intense study of astronomical tables and so forth". But he might well have blamed Gutenberg's printed books (the latest technology at the time).

So, what have researchers found so far?

Having parents with myopia increases a child's risk for myopia. But children can mimic their parents' potentially myopia-inducing lifestyle such as near work that requires focusing on close-up objects and studying a lot inside as well as inherit their genes.

After years of debate over whether myopia is due to genetic or environmental factors (with reading and screen use suggested), we now know it is an interaction of both genes and environment.

Myopia does not result from a single gene defect; more than 160 interacting genes contribute to the risk of myopia.

What are the environmental triggers that would explain an epidemic?

Many studies have looked at possible risk factors but only a few have come out consistently around the world: near work, years in education and lack of time spent outdoors in daylight.

Untangling the interactions is a challenge because these factors are interrelated, with children who study more spending less time outdoors.

Despite decades of parents warning children, no study has shown that sitting too close to the television causes myopia.

In the past two years, five papers (1, 2, 3, 4 and 5) have looked at myopia and personal electronic devices. Some, but not all, have found an association between the amount of screen use and myopia. But this does not mean screen time itself causes myopia.

Instead of reading from books, children are reading more from screens and changing the nature of their near work. Rising rates of myopia are related to near work behaviours, rather than screen use in particular.

Children are also changing the way they use screens. The simple idea that screen use occurs indoors was completely overthrown by the Pokemon Go craze, as gamers headed outdoors with their smartphones in search of virtual treats.

In addition, we now have children using virtual reality goggles to play games or even study.

Australian guidelines recommend:

There is no rigorous scientific basis for these time limits in relation to visual health. But a recent study showed a large percentage of children exceeded these time limits.

Potential health issues relating to screen time are diverse. Sleep, posture, level of physical activity and behavioural issues are additional reasons for concern.

Unlike previous generations, most children today experience a lot of screen time. But we don't have consistent findings for use of television, computers, tablets, smartphones or even virtual reality goggles themselves as the main cause of myopia.

We clearly need some very large, well-conducted studies where we directly measure the use of screen time across a wide range of health issues from infancy to young adulthood.

Some cities in China are trialling scheduled time spent outdoors at school to see if it prevents or decreases the progression of myopia in children.

In Australia, we need tailored messages to encourage kids to spend more time outdoors if they are inside reading or using screens too much.

Manifestations of Inflammation and Pain Flares in Rheumatoid Arthritis – Rheumatology Advisor

January 10th, 2020 9:53 pm

Flaresare common in patients with rheumatoid arthritis (RA), but many experiencediscordant inflammation and pain flares, according to study results publishedin BMC Rheumatology.

The study included patients from the Early RA Network (ERAN) cohort (n=719). The researchers assessed patients annually up to 11 years after presentation (3703 person-years of follow-up). The researchers defined flare events in 2 different ways, which were analyzed in parallel: Disease Activity Score-28 (DAS28) or pain flares. DAS28 flares satisfied Outcome Measures in Rheumatology (OMERACT) flare criteria: increases in DAS28 since the previous assessment (1.2 points if active RA or 0.6 points if inactive RA). Pain flares were defined as a 4.8-point worsening of Short Form Health Survey 36-Bodily Pain score.

Theresearchers analyzed the first documented episode of each DAS28 and pain flarefor each patient. They then used latent class analysis to determine subgroupswith DAS28 and pain flares and compared clinical courses between subgroups.

Afteranalyzing the results, the researchers found that 45% of patients experiencedDAS28 flares and 52% experienced pain flares. Flares were usually discordant,with 60% of patients with DAS28 flare not concurrently in pain flare and 64% ofpatients with pain flare not concurrently in DAS28 flare.

Theresearchers identified 3 distinct DAS28 subgroups: the first characterized byincreases intender/swollen joint count (14.4%); the second by increases in symptoms (13.1%);and the third, which displayed lower flare severity (72.5%). They alsoidentified 2 discrete pain flare subgroups: in the first the pain flare occurredfollowing low disease activity and symptoms (88.6%) and in the second occurredon the background of ongoing active disease and pain (11.4%).

WhileDAS28 and pain flares had observed differences, both were associated withincreased disability, which persisted after the flare.

Thestudy included several limitations. The researchers noted that assessments maynot have captured data during a flares peak, while pre-flare data may notreflect the patients best clinical status. In addition, missing data may haveinfluenced the study findings.

DAS28and pain flares are discrete entities indicative of differing underlyingmechanisms, but both have immediate patient impact and lead to longer termdisability. Identifying and understanding RA flare subgroups should guidetreatment, the researchers wrote.

Which Joints Are Most Affected by Arthritis? – Yahoo Lifestyle

January 10th, 2020 9:53 pm

Like many diseases, arthritis is not a one-size-fits-all illness. To explain it in the easiest wayor in the most general termsthink of arthritis in two overarching categories. "As a broad classification, you have inflammatory versus non-inflammatory arthritis," explains Dr. Natalie Azar, rheumatologist and clinical assistant professor in the department of medicine at NYU Langone Health. "We don't categorize arthritis by the joints affected, but by inflammatory versus non-inflammatory." Osteoarthritisthe non-inflammatory kindis synonymous with wear and tear. (It's generally the kind that occurs as you get older.) Rheumatoid arthritisthe inflammatory kindis systemic and associated with autoimmune diseases.

Osteoarthritis most commonly affects the knees ("Think of how many people get knee replacements," Dr. Azar says), as well as the hips and hands. While it is genetic, and can be associated with trauma, like fractures. Obesity can also lead to osteoarthritis, since you're putting too much pressure on your joints, Dr. Azar explains. For people afflicted with osteoarthritis, there unfortunately aren't any FDA-approved medicines that can change the course of the disease. "We're still left treating symptoms," Dr. Azar says. Physical therapy can help strengthen jointsand taking Tylenol to ease pain and inflammation can offer short-term, immediate relief to those dealing with both types of arthritis.

Rheumatoid arthritis, on the other hand, can affect small or large jointstypically four or more. "It's symmetrical, so both sides of the body are involved," Dr. Azar says. "It's not just one knee, but both knees, or both wrists, or both joints of the hands. It's also associated with swelling, stiffness that lasts for more than an hour, and pain." Rheumatoid arthritis, she says, can also affect the kidney and lungsit's not just a joint disease. Fortunately, with rheumatoid arthritis, there are disease-modifying therapies (or anti-rheumatic drugs) that patients can take in order to put them into remission and reverse damage, Dr. Azar explains.

And while diet doesn't cause either type of arthritis, once you have it (regardless of type), eating an inflammatory diet can exacerbate the situation, Azar says; alcohol, processed sugars, and trans fats are the usual culprits. Following an anti-inflammatory diet full of fruits, vegetables, lean protein, and healthy fats may help boost the immune system, fight inflammation, and strengthen bones, the Arthritis Foundation says. Azar refers patients to the site for information and health tips on what to eat while living with arthritis, but she adds that the dietlike the diseaseis not one-size-fits all. Some people can't tolerate nightshade vegetables like tomatoes, eggplants, and potatoes, for example, so you just have to experiment and tailor your diet to see what makes you feel your best.

Arthritis: Include this type fish in your diet to alleviate joint pain – Express

January 10th, 2020 9:53 pm

Arthritis is an umbrella term for a number of conditions that cause swelling and tenderness in one or more of your joints.

The main symptoms of arthritis are joint pain and stiffness, which typically worsen with age.

Osteoarthritis and rheumatoid arthritis are the two most common types of arthritis, and, while these conditions cannot be cured, lifestyle interventions can be taken to alleviate joint pain associated with them.

Certain foods, for example, have been shown to contain anti-inflammatory properties, and fatty fish, such as salmon, mackerel, sardines and trout, are high in omega-3 fatty acids, which have shown to produce potent anti-inflammatory effects.

In one small study, 33 participants were fed either fatty fish, lean fish or lean meat four times each week.

After eight weeks, the fatty fish group had decreased levels of specific compounds related to inflammation.

Echoing these findings, an analysis of 17 studies found that taking omega-3 fatty acid supplements decreased joint pain intensity, morning stiffness, the number of painful joints and use of pain relievers in patients with rheumatoid arthritis.

Exercise may seem counterintuitive if you are in pain, but in addition to helping you lose weight, it can also help to reduce and prevent pain associated with arthritis.

As the NHS points out, exercise can also help:

As long as you do the right type and level of exercise for your condition, your arthritis won't get any worse, explains the health body.

It added: Combined with a healthy, balanced diet, regular exercise will help you lose weight and place less strain on your joints.

According to Versus Arthritis, the UK's largest charity dedicated to supporting people with arthritis, you should aim to do at least 30 minutes of exercise that makes us a bit short of breath five times a week.

Its also recommended that you spend 30 minutes a day on our feet, such as walking or climbing stairs, notes the charity.

If you have joint pain, start gently and gradually increase the length of time youre exercising. You can break this into smaller chunks if you need to, advises the health body.

It added: Doing five to ten minutes of exercise each day is important to keep your joints moving and your muscles strong.

As the NHS explains, if you have arthritis, carrying out tasks around the home can be a challenge, however, making some practical changes to your home and changing the way you work should make things easier.

Practical tips that could help include:

An occupational therapist can also help if you have severe arthritis that's affecting your ability to move around your home and carry out everyday tasks, such as cooking and cleaning, notes the health body.

They can advise about equipment you may need to help you live independently, and, depending on the exact nature of your condition, your GP may be able to refer you to an NHS occupational therapist, adds the health site.

Vitamin D deficiency symptoms: A lack of the vitamin may cause pain in this body part – Express

January 10th, 2020 9:53 pm

Vitamin D is a fat-soluble vitamin that is naturally present in very few foods, and available as a dietary supplement. Vitamin D plays a role in insulin production and immune function. Although the amount of vitamin D adults get from their diets is often less than whats recommended, exposure to sunlight can make up the difference.

Research has found that vitamin D may play a significant role in joint health, and that low levels may increase ones risk of rheumatological conditions such as arthritis.

Several studies have found low blood levels of vitamin D in patients with osteoarthritis of the hip and knee.

In another study of more than 2,000 people, researchers found that vitamin D deficiency was strongly associated with a disabling symptoms among those with rheumatoid arthritis.

DONT MISS

Why does a lack of vitamin D affect bones?

Vitamin D helps the bones absorb calcium, which is vital to bone health.

The vitamin is also crucial for muscle movement, communication between nerves, and fighting inflammation.

According to the Arthritis Foundation, people who take oral steroids have a vitamin D deficiency twice as often as people who dont take them.

Oral steroids are a common treatment for people with arthritis.

What studies have said

In a study with Endocrinology and Metabolism, the link between vitamin D and rheumatoid arthritis was investigated.

The study concluded that vitamin D deficiency is highly prevalent in patients with rheumatoid arthritis and that vitamin D deficiency may be linked to disease severity in rheumatoid arthritis.

As vitamin D deficiency has been linked to diffuse musculoskeletal pain, these results have therapeutic implications vitamin D supplementation may be needed both for the prevention of osteoporosis as well as for pain relief in patients with rheumatoid arthritis.

In addition to helping prevent arthritis, getting enough vitamin D may also lower the risk for other autoimmune diseases like cancer, heart disease, type 2 diabetes, bone fractures, depression and the flu.

During winter its highly recommended to take vitamin D supplements.

Doctors recommend taking 800 to 1,000 IU of vitamin D a day. Other symptoms of a vitamin D deficiency include pain, infections, gastrointestinal problems, depression and weak bones.

Secukinumab has Early and Sustained Efficacy on Enthesitis in Patients with Psoriatic Arthritis – Pharmacy Times

January 10th, 2020 9:53 pm

Secukinumab has Early and Sustained Efficacy on Enthesitis in Patients with Psoriatic Arthritis

Enthesitis is inflammation of the entheses, the site where ligaments or tendons insert into the bones. Common locations for enthesitis include the bottom of the feet, the Achilles tendons, and the places where ligaments attach to the ribs, spine, and pelvis.2

Patients with enthesitis are known to have worse outcomes than patients without enthesitis. Using pooled data from the FUTURE 2 and 3 studies, a research team explored the use of secukinumab to limit enthesitis in patients with PsA.1

FUTURE was a phase 3 randomized, double-blind, placebo-controlled multicenter study that analyzed the 24- to 52-week efficacy, safety, and tolerability of subcutaneous secukinumab in prefilled syringes. Researchers used the Leeds Enthesitis Index (LEI) that consists of 6 sites: bilateral Achilles tendon insertions, medial femoral condyles, and lateral epicondyles of the humerus. Tenderness at each site is quantified by a number scale: 0 means nontender and 1 means tender.4

The post hoc analyses included the resolution of enthesis count (EC=0), median time to first resolution of enthesitis, and shift analysis of baseline EC (1, 2, or 3-6) to full resolution (FR) stable (similar or reduction of EC), or worse (EC > baseline).1

Sixty-five percent (466/712) of patients had baseline enthesitis. In the overall population, FR was achieved as early as week 16 in 65% (300 mg) and 56% (150 mg) versus 44% in the placebo group, with further improvements to 91% (300 mg) and 88% (150 mg) at week 104. The majority (89%) of patients without enthesitis at baseline maintained their status at week 104.3

In patients with EC of 1 or 2, shift analysis from baseline to week 24 showed that more patients achieved FR with secukinumab 300 mg and 150 mg versus placebo, whereas no difference between secukinumab and placebo was shown in patients with more severe symptoms with an EC of 3 to 6. Improvements in efficacy outcomes were similar in patients with or without enthesitis treated with secukinumab 300 mg.1

Secukinumab provided early and sustained resolution of enthesitis in patients with PsA over 2 years, the study authors noted.1 Secukinumab 300 mg provided higher resolution than 150 mg in patients with more severe baseline EC and showed similar overall efficacy in patients with or without enthesitis.

JIA Orofacial Pain Linked to Stress, Activity Limitations, Study Shows – Juvenile Arthritis News

January 10th, 2020 9:53 pm

People withjuvenile idiopathic arthritis (JIA) who experienceorofacial pain pain in the mouth, face, and jaw have more stress, limitations on daily activities, disease activity, and systemic inflammation than those who do not, a study reports.

The study, Orofacial pain in juvenile idiopathic arthritis is associated with stress as well as psychosocial and functional limitations, was published in the journal Pediatric Rheumatology.

The hallmarks of JIA are swelling of the joints, pain, and stiffness, typically in the knees, hands, or feet. JIA can affect other joints as well, such as those that connect the jaw to the head, which are known as the temporomandibular joints (TMJ).

Up to 96% of children with JIA develop TMJ arthritis, where stiffness, crepitus (joint popping), and restricted mouth opening are often reported.

Chronic or recurrent pain and disability in children and adolescents can limit their ability to function and grow properly. Many of these patients refrain from going to school and avoid engaging in social activities due to the psychosocial stress and pain associated with the disorder.

To investigate the relationship between psychosocial stress, along with inflammatory activity, and pain and function of the jaw, a group of researchers in Sweden studied 45 JIA patients ages 6 to 16. Sixteen children without JIA were also included as controls.

A clinical assessment, including both a physical and a psychosocial component, was conducted on all participants by one dentist.

Pain intensity and pain-related disability were assessed with the Graded Chronic Pain Scale. Limitations to jaw function was evaluated using the Jaw Functional Limitation Scale.

A four-item Patient Health Questionnairewas used to assess depression and anxiety symptoms. The Pain Catastrophizing Scale was applied to determine the degree of catastrophizing (believing pain is worse than it is), and the 10-item Perceived Stress Scale was used to evaluate stress.

The Childhood Health Assessment Questionnaire was used to assess ability to conduct daily life activities among children with JIA, while the body-drawing part of the McGill Pain Questionnaire was used to record pain locations.

Finally, the team used the Juvenile Arthritis Disease Activity Score,which includes an active joint count, a physician global assessment, a parent global evaluation, and the erythrocyte sedimentation rate (an indicator of systemic inflammation).

Results showed a strong association between experiencing orofacial pain and stress. Among patients scoring higher (worse) than normal in perceived stress, eight out of ten had self-reported orofacial pain.

Orofacial pain also significantly correlated with pain-related disability, depression, pain catastrophizing, and limitations in daily activities.

The team then compared clinical and psychosocial factors of JIA patients who experienced jaw pain with those who did not.

Orofacial pain was significantly associated with pain intensity, maximum mouth opening, and limitations on jaw functioning. JIA patients with orofacial pain also had higher disease activity and systemic inflammation than those without such pain.

In contrast, neither depression nor pain catastrophizing were linked to orofacial pain.

This study indicates that orofacial pain in patients with JIA is associated with stress, psychological distress, jaw dysfunction and loss of daily living activities, the researchers said.Pain intensity seems to be the major aspect related to these factors. In addition, increased disease activity with more joint involvement seems to be an important factor contributing to orofacial pain in JIA.

He worked as a medical scientist for 18 years, within both industry and academia, where his research focused on the discovery of new medicines to treat inflammatory disorders and infectious diseases.

Why I Relate to ‘Survivor’ as Someone With Rheumatoid Arthritis – Yahoo Lifestyle

January 10th, 2020 9:53 pm

I spent my summer watching Survivor. You know, the reality television show that shows people living in rugged, beautiful climates, taking part in challenges and voting each other off the island every few days. I was a fan when it started in 2000, but over the years, schedules and life turned my attention to other viewing pleasures.

Back then, I liked the beautiful settings and the intrigue among the cast members who were creating these intense relationships from living together in harsh circumstances and then back-stabbing those same people as part of the game. But what I really loved were the challenges. These usually took the form of giant obstacle courses, either on a sandy beach or in the ocean. Contestants swam, jumped, dug, wiggled and ran their way to winning rewards or immunity from being voted off. I liked to think about how I would do that and what skills I would bring to such fun.

But this summer was different.

After years away from the show, this summer I found 34 seasons on Hulu and binged my way through season after season. I was able to do this because this summer a rheumatoid arthritis flare that included severe back pain and fatigue put me in bed with just a phone and a remote. I spent hours watching Survivor, drawn in by something internal and strong. At first, I wasnt sure what the lure was, but then it occurred to me.

I saw myself on that screen, except this time through the lens of my new reality.

When contestants would swim into the ocean, climb a ladder to retrieve a special key, then swim back, struggling to pull themselves on to a platform, I saw myself. I recognized that deep, unshakable fatigue, even though the genesis was different for them than for me.

When it rained for five days straight and their fire went out so they could only eat coconut in wet clothes, I recognized the despair on their faces from not knowing when this particular pain would end.

When a downcast contestant would dig deep and finish a challenge just when they needed the win, I found inspiration in my own battle for a win.

When their families showed up as a surprise reward, I wept from knowing how sustaining that unconditional love is and the hope it brings.

Yes, I saw myself in these Survivor contestants. No, I wasnt wearing a bathing suit on national TV or wrestling another person to try to win fishing gear, but I was in my own battle. It was a battle that included pain, despair, fatigue and hope. It was a battle that meant I had to will all my internal strength to be the victor. And as summer ended and my pain eased, I realized that I too, in my own reality, could call myself a Sole Survivor.

Doctors Missed Her RA Symptoms in Pregnancy. She Found a Way to Thrive Anyway – HealthCentral.com

January 10th, 2020 9:53 pm

Brooke Baker was sleeping soundly one night in 2005 when suddenly she woke up with new and excruciating pain in both shoulders. "I remember it so well, and I had no idea what was going on," recalls the Oklahoma native, now 39. "The pain was like someone was injuring me, and I couldn't go back to sleep for hours."

In the agonizing days to come, a perplexed and frightened Baker swapped out her mattress and her pillow and would prop herself up to try and alleviate the unrelenting stabbing sensations.

I just thought, Well, it must be one of those things, she says. But then that thing moved to her elbows, the next week to her wrists, and a week later, to her hands. I had never had any pain issues, and this all made me feel so debilitated. Having such painful arms and hands was especially unfair. Baker had been a full-time music minister at church for three years, playing the piano.

Realizing the continuing torment was anything but random, she went to see her OB/GYN. After all, she was eight weeks into a miracle pregnancy at the time (shed been told shed never be able to have children). The last thing she needed was unexplainable pain.

When I said: Something's wrong, during that office visit, both the nurse and the male doctor I saw told me I should be grateful to be pregnant and basically to suck it up, she says. Baker vowed to find a new OB/GYN, which she did four months into her pregnancy. At that point the pain was in every joint, from her neck to her toes.

This doctor was a little gentler, he did really listen, but he was also a poor communicator, Baker says. Because her symptoms were suspicious, the doctor did refer her to a local rheumatologist who ran some tests to confirm or rule out the possibility of rheumatoid arthritis (RA). That was the first mention that this disease could be the cause of her pain.

The rheumatologist later called me to report the results showed nothing, Baker says. Later, he also told me it definitely wasn't RA and that RA gets better when you're pregnant.

With her diagnosis still undetermined, the now-devastated and overwhelmed mother-to-be was in too much pain to work, so she quit and moved back in with her parents, because on top of all of this, her marriage had fallen apart.

I was on the couch for almost seven months, she says. The pain got better for about six weeks, between months seven and eight, says Baker. I finally felt better and hoped I was over it all.

It wasn't to be. The pain returned full force during her ninth and final month of pregnancy as she was also getting huge, she says. Almost sheepishly, she returned to her OB/GYN for pain relief. I didn't want anyone, including him, to think I was crazy.

That doctor told her: When you have the baby, you won't hurt anymore. Wrong: Her pain kept steadily increasing.

The calendar had flipped to 2006 now and the big day came to deliver. A c-section was complicated by my previous abdominal surgeries and resulted in a longer hospital stay and blood transfusions, Baker says. But my baby boy, Jackson, was healthy and I was thrilled!Still, her intense joint pain persisted. How would she manage being a single mother? Her doctor then told her: When you stop breastfeeding, you won't hurt anymore. But when she stopped after a year, her pain continued on.

I thought, If I just tough it out longer, I'll be OK, she says. I was pretty gullible, believing everything I was told.

Being a single mom is hard enoughbut fate would deal her another unlucky hand. Baker was worried: It seemed that Jackson, then 17 months old, was drinking constantly. Then one day he began stumbling, he couldnt see normally, and he'd been losing weight. She knew something was terribly wrong.

A doctor visit and blood tests showed his blood sugar was more than 750 mg/dL when he was diagnosed with type 1 diabetes. (Normal blood sugar for a person without diabetes ranges from between 70 and 100 mg/dL.) Frequent urination, thirst, fatigue, and weight loss are common symptoms of the disease.

He was too young to tell me what was wrong, how he was feeling, says Baker. His behavior changes and voice gave her clues as she tested his blood sugar regularly.

Baker was in nursing school by this time, still living with her parents and not working, except to play music part-time at a little, bitty job, she says.

In those first stressful weeks after his diagnosis, I'd stay up studying until 2 a.m., check my son, then sleep till 5 a.m. or 6 a.m. and then start it all over again, Baker says, knowing it was all worth it, even though then, it all felt almost unbearable.

I went through the roof at that time, Baker says, recalling seemingly insurmountable stress. Three weeks after her son's diagnosis, she finally saw her primary-care provider, where she wished she'd started, and tearfully confessed that she couldn't move her arms.

I couldn't even lift my baby. I'd have to scoop him, she says. I'd spend 30 minutes in the shower, in the warm water, to help get my arms moving in the morning, because they were 'locked' at a 90-degree angle.

The situation was terrifying. The baby relied on me for everythingme, the single mother trying to do everythingand I could barely take care of myself. I couldn't open a baby food jar, and didn't feel safe bathing him alone, Baker says. Thank goodness for my mother. But this was about survival, and I had to go on.

Her healthcare provider immediately did new blood tests for RA and he called Baker the same night to confirm positive results. "I was so glad to have an answer that I wasn't even devastated by that news," she says. The previously reported test resultsthe ones that ruled out RA while she was pregnantmust have been a mistake, she thinks now.

Her doctor quickly referred her to another rheumatologist who didn't just mumble and grunt at me, she says. He prescribed medication, and I started it in December 2007.

As for why Bakers OB/GYN had earlier ruled out RA because her symptoms continued during pregnancy, which, he said, was not the normit turns out he was half right and half wrong.

The latest research in UpToDate, an evidence-based clinical resource, says approximately 50% to 60% of pregnant women diagnosed with RA do have improvement in their symptoms, usually starting in the first trimester. And no, it's not possible to predict which patients will improve and which will flare.

Even more specifically, a review recently published in The Journal of Rheumatology reported that disease activity improved in 60% of patients with RA in pregnancy and flared in 46.7% postpartum. The Arthritis Foundation says that may be because of the hormone and immune system changes that protect an unborn child may also help RA.

The RA medication her doctor started her on was methotrexate, and it still stabilizes Baker's RA. It's a disease-modifying anti-rheumatic drug also known as a DMARD and it's considered a first-line treatment for RA. As the Johns Hopkins Arthritis Center shares, its benefits include that it works fairly quicklyin six to eight weeksit works well, is easy to use, and isn't expensive.

Bakers joints throbbed when she started taking it. She'd feel good for a few days, and then after the next week's injection, the pain would return. It took seven months before I started to feel normal, again, but a year later I was pretty much functional and able to play piano again! she says.

Baker has gone back and forth between methotrexate pills and now-weekly injections. She feels so much better now that she shudders to remember the two miserable years she spent with no pain medication except acetaminophen.

No one ever gave me any, she says. They just said: Everyone hurts when they're pregnant.

Jackson, Bakers now 13-year-old son, has clearly inherited his mother's indomitable, can-do attitude. His spirit is undefeatable, and he just bounces back with a resiliency that's amazing, Baker says of her son. His hasn't been an easy life and he makes it look so easy.

When Jackson doesn't feel well, he doesn't let it bother him. Instead he asks: "Can I go to school tomorrow? Baker patiently explains that he should rest and asks him to pace himself.

She homeschooled him until fifth grade and he thrived when he eventually attended school. Hes so motivated, just so driven, and wants to get into Harvard, she says. Hes also creative and talented and plays the lead in lots of school plays.

Getting to this point has meant thatmuch like his momJackson has had to overcome the awful moments that come with chronic illness. Baker recalls when, as a child, Jackson would say, I don't want to be diabetes, Mommy.

That was just heart-wrenching, Baker says. Now he's so calm, and he says to me: Diabetes isn't all that bad. There are more good things than bad things. That stumps me, and I just go blank, without a response.

He has said he doesn't quite understand it all, about why he hurts and can't get better, and why she hurts, too. Hes starting to assess when my hands and feet swell, and he says Im so sorry you have this rheumatism, she says.

Baker doesn't dwell on sorry, but stays active. She is part of the Diabetes Patient Advocacy Coalition that advocates for more affordable insulin. Shes been to Washington, D.C. three times in 2018 and 2019 to lobby her legislators to decrease the price of insulinand she intends to continue. As a partial result of the groups nationwide efforts, the Insulin Price Reduction Act was introduced July 22, 2019.

Baker isnt looking for a standing ovation, but she measures her lifes progress quietly every day, her eye firmly on the prizeand her goals.

With her pain controlled, and now her stress, Baker, who lives with her son, can focus on her accomplished life. She began that nursing degree in January 2008, around the time both she and her son were diagnosed with their diseases, and she finished in May 2010. Then in January 2019, she finished her masters degree in nursing and now works as a professor at a local university teaching the next generation of nurses. She will pursue her Ph.D. next, with the goal of becoming a university dean. Then there are more personal goals.

I want to be more active with my son when I can, Baker says. My body's getting physically stronger, and we're planning to do some runs together soon.

And theres travel. The pair plans to visit all 50 states. She's done 47, and Jackson has logged 10. Baker still plays music for therapy, not performing, but singing joyfully with her son in the car.

Shes relieved not to have to fight her body anymore. I'm trying to work with it instead of against it, she says. I dont accept it as: Boy, I love having this, but it's better than hating it all the time.

RA Reminds Her That Pain is Real, and Personal

Baker takes a whole-body approach to managing her RA. She consistently takes her medicationon timeand also likes to use essential oils for aromatherapy and for minor relief, applying them to her hands. To maintain her overall balance, she practices yoga, her favorite activity. She embraces deep breathing and calming apps on her phone, such as Calm and Headspace.

I do my part, and because I have a spiritual side, I leave the rest because I can't control it all, she says.

Baker remembers the time when doctors didnt hear her when she reached out for help with pain and she felt sheepish about pressing themnot so now. She encourages others with chronic illness to speak up for themselves. Youll experience a real difference between advocating and not, and if you dont find support in doctors you have, keep trying until someone really listens to you and works with you, she says.

It's made her a better nurse, especially when a patient shares about their pain. She learned in nursing school that pain is what the patient says it is. Baker knows this firsthand. Those months of gritting through intense pain during her pregnancy could have been shortened if only someone had really listened to her symptoms and pushed for treatment. Now Baker is doing the listening (and teaching) and her patients are lucky to have her.

Tai-Chi, Topical Capsaicin Among the New Treatment Recommendations for Osteoarthritis – Rheumatology Network

January 10th, 2020 9:53 pm

The American College of Rheumatology (ACR), in partnership with the Arthritis Foundation, has issued treatment guidelines for osteoarthritis of the hand, hip and knee. This is the first update since 2012.

New in this release is the inclusion of patients in the decision-making process, which the Arthritis Foundation described a "patient-centric guidelines."

Traditionally, the patient voice has been invoked, but not always present, as guidelines are developed, said Guy Eakin, senior vice president of scientific strategy for the Arthritis Foundation. Through our partnership we were able to marry the ACR rheumatology expertise with the Live Yes! patient community to pioneer a process assuring guidelines that treat patients reflect the unique perspectives of the patients who will receive them.

The guidelines, which will be published in February in an ACR journal, emphasizes the adoption of basic therapeutic treatments which were strongly recommended. These include: weight loss; self-management programs to build fitness skills and exercise goalsetting. Previously consider conditions recommendations, the following were upgraded to strong recommendations: mind-body approaches such as tai-chi; topical NSAIDs for knee and hand osteoarthritis; oral NSAIDs and intra-articular steroids for knee and hip osteoarthritis.

Other recommendations include:

Lyme disease: Justin Bieber’s tick-bite illness can cause joint pain, heart problems, and depression – The Conversation UK

January 10th, 2020 9:53 pm

Justin Bieber recently announced that for the last couple of years hes been battling Lyme disease. Lyme disease, which is caused by the bacterium Borrelia burgdorferi, can be transmitted to humans if theyre bitten by an infected tick. In fact, its one of the most common tick-borne diseases in the west. An estimated 300,000 people in the US are diagnosed with it every year. The disease causes a range of debilitating symptoms, which can include severe headaches, neck stiffness, arthritis, joint pain and rashes. These symptoms can last for months or even years.

After being bitten, most people develop a red, circular rash, which may slowly expand beyond the bite site. Only around 20-30% of people will develop the characteristic bullseye rash. Without prompt treatment, the bacteria will spread from the bite site to tissues and organs, leading to additional skin lesions and a range of debilitating and persisting symptoms, such as pain, fatigue, memory problems and arthritis.

Perhaps alarmingly, instances of Lyme disease have actually become more common. In England and Wales the number of cases has increased from 1,134 in 2016 to 1,579 cases in 2017. The increase might be explained by a number of factors, including global warming (ticks survive better in warm weather) and increasing wildlife populations. Better diagnostic tools and increased awareness might also explain the surge in Lyme disease diagnoses.

Lyme disease can have a considerable impact on many aspects of the lives of the patient and their families. In severe cases, patients can be bedridden or wheelchair-bound for years without knowing if they will recover. Affected people may also experience anxiety, depression or distress, which can reduce their quality of life and deeply affect their mental wellbeing potentially even resulting in thoughts about suicide.

In most cases, a person will be diagnosed with Lyme disease based on whether they have the illnesss characteristic skin lesions especially if they live in an area where ticks carry Lyme disease. Although blood tests can also be used, these tests might only be 30-40% effective at detecting the disease in its early stages. But if the disease has already spread throughout a persons body, these results can be 100% accurate.

Giving a clear diagnosis of Lyme disease can be difficult, however. This is because many patients have a range of non-specific clinical symptoms, such as fatigue, malaise, headache, fever, sweats, joint aches and brain fog. Disease test results might also be similarly difficult to interpret, especially in patients that do not have the hallmark skin rash of Lyme disease and lack a recent history of exposure to tick bites. This makes dealing with the lingering infection difficult, especially where tests give inconclusive results.

In fact, people suffering from Lyme disease can also suffer from other tick-borne illnesses, such as babesiosis, which can be transmitted with Borrelia burgdorferi during the tick bite. This makes treatment even more complicated. As well, there is still some controversy about the right length of effective antibiotic therapy to treat patients with persistent, chronic Lyme disease. As a result, patients can, and usually do, feel helpless amid conflicting medical advice in fighting the disease.

Lyme disease is primarily treated with antibiotics. Early skin lesions and symptoms can be treated with the oral antibiotic doxycycline, usually for anywhere between ten to 21 days. Patients with neurological symptoms (including meningitis and encephalitis), heart inflammation or arthritis, are usually treated with a two-week course of intravenous ceftriaxone therapy. In most cases, timely diagnosis and prompt antibiotic treatment can improve symptoms.

But a misdiagnosis or late diagnosis can result in long-term illness, excessive use of antibiotic therapy, and expensive healthcare costs. Ignorance of the complex nature of this illness, especially the associated mental health issues, will further delay recovery. Dealing with these psychosocial problems regardless of whether they were triggered by Lyme bacteria or not can complement treatment and promote a quicker recovery.

Continued research and awareness about Lyme disease will be important for improving treatment and diagnosis. Developing more reliable diagnostic tests, identifying which patients are most likely to benefit from which antibiotic treatments, and taking measures to control tick populations will all be important for reducing instances of this disease in the future.

People can cut down on their risk of contracting Lyme disease by covering their skin in tall, grassy, wooded areas where disease-carrying ticks thrive. If you think youve been bitten by a tick, contact a doctor or health professional.

Cannabinoids in Medicine Part 3: Psoriasis and Rheumatoid Arthritis – Open Access Government

January 10th, 2020 9:53 pm

Endocannabinoids, as well as several phytocannabinoids, have been shown to influence immune functions, regulating inflammation, autoimmunity, antitumourigenesis, antipathogenic responses and other processes.1 Numerous in vitro and in vivo studies have examined the therapeutic potential of cannabinoid signalling in inflammation-associated diseases (e.g. psoriasis) and attempted to dissect the complex immunological effects of cannabinoids.

Psoriasis is a chronic inflammatory disease of the skin, characterised by excessive proliferation of keratinocytes that results in the formation of thickened scaly plaques, itching and inflammatory changes of the epidermis and dermis.2 The underlying pathophysiology involves activation of classes of T-cells and their interaction with dendritic cells and other cells of the innate immune system, including neutrophils and keratinocytes.3

The following pre-clinical studies support the use of cannabinoids in the treatment of psoriasis:

A 2003 study in Journal of Clinical Investigation demonstrated that the cannabinoid receptors CB1 and CB2 are present in human skin cells, including keratinocytes;4

A 2003 study showed that anandamide, an endogenous CB receptor ligand, inhibits epidermal keratinocyte differentiation (abnormal keratinocyte differentiation is a hallmark of psoriasis);5

In 2004, a study in the Journal of Neuroimmunology used an in vivo mouse model to show that THC can shift the development of the predominantly pro-inflammatory T helper 1 (Th1) cell to the more anti-inflammatory (Th2) cell type profile;6

A 2007 study, published in the Journal of Dermatological Science, demonstrated that a range of cannabinoids inhibit keratinocyte proliferation in hyperproliferating human keratinocyte cell lines.7 The cannabinoids inhibited keratinocyte proliferation in a concentration-dependent manner. The activity of CBN (not significantly active at CB1/CB2 receptors) indicates more than one mechanism of action;

In 2011, a study using human cultured keratinocytes and a skin organotypic culture model, provided evidence that anandamide markedly suppresses keratinocyte proliferation and induces cell death, both in vitro and in situ. The cellular actions were mediated by CB1 and transient receptor potential vanilloid-1 (TRPV1). The cellular effects of anandamide are most probably mediated by Ca2+ influx and intracellular accumulation via the non-selective, highly Ca2+-permeable ion channel TRPV1. The study was published in the Journal of Investigative Dermatology;8

A 2016 study, published in the Annals of Dermatology, investigated the effect of CB1 agonists on mast cell activation. The authors found that CB1 agonists inhibited the release of inflammatory mediators and markedly and dose-dependently suppressed cell proliferation.9

RA is one of the most prevalent autoimmune diseases and one of the main causes of disability globally, causing pain, joint malformation and joint destruction.10 Preliminary evidence suggests that cannabinoids have a role in the future treatment of RA.

In one study,11 protein and mRNA expression of endocannabinoids, AEA and 2-AG, and cannabinoid receptors, CB1 and CB2, were found in synovial tissue obtained from 13 patients diagnosed with RA and undergoing arthroplasty whilst synovial tissue obtained from healthy volunteers was negative for the same endocannabinoids. Another study of synovial tissue from patients with RA12 found that of inflammatory cytokines, IL-6 and IL-8, which are stimulated by synovial cells, were attenuated by low concentrations of the synthetic cannabinoid WIN 55,212-2.

Furthermore, three different research groups achieved improvement in mice with collagen-induced arthritis (CIA), following treatment with various cannabinoids;13 The use of cannabinoids for the treatment of pain associated with RA has been assessed in only one 2006 clinical trial, where 58 patients with RA were allocated either nabiximols or a placebo.14 Compared with placebo, patients treated with nabiximols exhibited decreased pain along with improved sleep quality.15

Chilled to the bone the link between cold weather and joint pain – StarNewsOnline.com

Chilled to the bone. Many of us have used this expression after spending some time outdoors in the cold weather. But it leads to perhaps one of the most common questions posed to all rheumatologists: Does the weather have any impact on our bones or joints? Many people are convinced that they are able to predict the weather based on increase in joint or back pain. A commonly quoted study conducted more than 10 years ago seemed to support this notion by showing that every 10-degree drop in temperature as well as a drop in barometric pressure can increase joint pain.

The Arthritis Foundation even provides an arthritis index on its website that is based on local temperature and barometric pressure that anyone can use if they chose. So mystery solved, right?

Not so fast. Like so many things in medicine, our knowledge is always evolving. One of the more recent and largest studies to date found absolutely no connection between changes in weather and joint pain. This conclusion was based on very comprehensive data collected from over 10 million doctor visits. And then there was another recent Dutch study that showed an increase in barometric pressure and humidity correlated well to increased joint pain, which directly contradicted the previous notion that the drop in barometric pressures was the culprit for your achy bones.

Digesting all of these conflicting findings can be a challenge for clinicians and patients alike. The reality is that the verdict is likely still out on this complex issue and there is more data to come. Until we get some more clarity, my recommendation is to go with whatever your body tells you. After all, no science can compete with personal experience that tells you that the ache you feel in your knees probably means that you should get your umbrella ready.

CBD Technology and How CBD Patches Are Helping People – HealthTechZone

January 10th, 2020 9:53 pm

Thanks to the advancement in technology, it seems like CBD is making its way into everything nowadays. The list of CBD-infused products includes intimate gels, sparkling water, chocolate, gummies, shampoo, skin creams, coffee, and so much more. One of the latest addition to the list is CBD patches.

As you probably already know, patches have been existing for many years already and are famous for effectively delivering healthy ingredients into the bloodstream. Today, its now getting utilized as a vehicle for CBD to get into your body and help you enjoy the benefits of the chemical.

The Technology Behind How CBD Patches Are Created

The technology used in creating CBD patches has already been around for decades, despite the product being relatively new in the market. The technological concept is much similar to birth control or nicotine patches, added with a couple of twists to ensure that the patch can deliver CBD to the bloodstream effectively.

CBD patches contain a dose of Cannabidiol molecules, infused in an isolated oil, gel, or solution. They also have carriers and permeation enhancers, and because your skin has a low CBD concentration, the high concentration of the patch moves the Cannabinoid into your body.

CBD patches and their transdermal application continue to become famous as an alternative way to reap all the benefits that CBD supplements bring to the table. Many people also view it as a way to receive a prolonged treatment dosage while being discreet.

Like any other CBD-infused products available in the market today, CBD patches cant get you high since Cannabidiol functions differently than THC, the psychoactive element of Cannabis plants. Accurate, useful, and comfortable, CBD patches are as simple as they sound, even if the technological process they undertake is a bit complicated.

This post will help you take a closer look at CBD patches, how these products work, and how they can help people.

Whats A CDB Patch And How Does The Product Work?

If you want to picture out what CBD patches look like, you only have to imagine large band-aids since theyre very closely similar in appearance. Also, like a large band-aid, you can peel and stick a CBD patch to any location in your body. The only difference is that the CBD patches are pieces of plastic infused with Cannabidiol.

Unlike the typical CBD oils, the patches arent wet. Theyre dry so they can stick to your skin. Most users place them on venous parts of the body, including their arms, ankles, and wrists. They do this since those areas have the potential for a higher absorption rate of CBD into the bloodstream.

Cannabidiol patches function by following a complex chemical reaction with the users body. Your body heat will activate the pieces and causes them to release CBD molecules and other ingredients that they contain. Please take note that in addition to Cannabidiol, some patches may contain caffeine, melatonin, THC, and more. Once these molecules get absorbed through the skin, they make their way into the bloodstream, where the body can start processing the compounds. After that, youll then begin to experience the benefits of CBD.

Benefits of CBD Patches

One of the essential benefits of CBD patches is the efficient delivery of Cannabinoid to the body. However, there are other equally important benefits, as well.

Here are some benefits of CBD patches:

1. Better Compound Absorption - Whats the reason behind CBD patches better absorption? It starts with the fact that your lungs and stomach are excellent at preventing any chemical from entering your bloodstream, which is how other CBD products, such as vape and gummies, enter. While its great that such a defense mechanism is possible to protect your body when youve inhaled or ingested something harmful, it also means that anything beneficial that youve consumed may reach your cells with limited effects.

By using CBD patches, you can bypass the filtering organs of your body, so more of the compound makes it into the bloodstream. It results in less CBD needed for you to feel and experience the benefits of the chemical.

2. Pain Management - CBD patches, like other CBD-infused products, have shown to alleviate ailments-related pains in the body, including lower back pains, spinal cord injury, arthritis, cancer, multiple sclerosis, muscle spasms, chemotherapy, and depression.

You can use CBD patches to manage both acute and chronic pains. Like band-aids, youll have to apply the patch to the site or area where you feel pain, allowing the supplement to get delivered immediately or over a short period.

Some CBD patches can also last for three days through nanotechnology in the reservoir patch, so its best to weigh your options based on your needs.

3. Arthritis - One of the leading causes of disability in the USA is arthritis. More than fifty-four million adults in the country have arthritis, which is more common in women than men. One type of arthritis, osteoarthritis, affects thirty-one million in the country by causing joints inflammation.

Several studies have pointed out the effectiveness of transdermal doses of CBD to reduce pain and other symptoms related to arthritis.

Final Thoughts

Many CBD users prefer transdermal delivery because it can bypass the stomach, liver, and lungs entirely - the traditional organs that break down or filter the Cannabinoid. So, such a method of taking Cannabidiol can give you at least fifty percent up to one hundred percent of the value of the supplement.
