Dear Dietitian: Exploring the role of supplements in healing arthritis pain – Austin American-Statesman

Posted: August 19, 2020 at 8:53 am

Dear Readers,

When it comes to physical activities, have you concluded that youre not as young as you used to be? Maybe you were once a runner and now the knees dont bend like they used to. Or perhaps you were a star athlete in high school and now your star just isnt as bright. The body has gotten older, the joints stiffer, maybe its even affecting your everyday life. Its a foe that sometimes rears its ugly head in mid-life - its arthritis.

In the U.S., as many as 54 million people suffer from osteoarthritis (OA). The word comes from the Greek "osteon" meaning bone, and "itis" meaning inflammation. OA is the most common form of arthritis and occurs when the cartilage that cushions bones wears down over time. Joints can become painful, swollen and difficult to move. The most commonly affected areas are knees, hands, hips, lower back and neck.

Some supplements claim to ease arthritis pain, but do they work? Glucosamine, chondroitin and curcumin (found in turmeric) are three dietary supplements we will explore.

Glucosamine and chondroitin, often sold in combination, are two of the top-selling natural remedies for OA. In a meta-analysis of randomized controlled trials (the gold standard for research) found that glucosamine was more effective than a sugar pill in alleviating joint stiffness. At the same time, chondroitin was better at improving pain and mobility. The analysis did not find enough studies to draw a conclusion about the combination therapy of the two.

In the 2019 treatment guidelines, the Arthritis Foundation and American College of Rheumatology gave a conditional recommendation of chondroitin sulfate for hand OA. However, the National Center for Complementary and Integrative Health says the evidence on glucosamine for OA is unclear, and chondroitin isnt helpful. Still, these supplements have not found to be harmful.

Another popular remedy for OA is curcumin, the ingredient in turmeric that has anti-inflammatory effects. Another meta-analysis concluded that curcumin, in addition to conventional medicine, may be useful in treating arthritis symptoms. In another study, curcumin was found to be as effective in treating arthritis of the knee as the drug diclofenac. However, this study was small and only lasted one month.

When it comes to your health, be an informed consumer. A little homework may be necessary before purchasing a supplement for arthritis symptoms. The following websites will help you make a sound decision:

Consult your doctor before beginning any dietary supplement.

Until next time, be healthy!

newsGP – Managing post-acute issues in COVID patients: What GPs need to know – RACGP

Posted: August 19, 2020 at 8:53 am

News

Even people who experienced mild infection may have long-term symptoms.

Once the most severe phase of COVID-19 infection has passed, many patients experience long-term issues.These patients often describe themselves as long-haulers or as having long-COVID.As the number of Australians diagnosed with COVID-19 has grown, so too has the number of patients with post-acute issues.This has led many GPs to seek information on how to best manage these ongoing concerns. Melbourne-based GP Associate Professor Vicki Kotsirilos, founding Chair of the RACGP Specific Interests Integrative Medicine network, is one of them.I actually thought about that last week when I read an article about long-term effects [of COVID-19], she told newsGP.I thought, Okay, what will I be advising my patients?Associate Professor Kotsirilos says it is totally understandable that robust clinical guidelines are not yet in place to help GPs manage patients with long-term sequelae of COVID-19.COVID-19 is a new disease and it takes a while for health authorities to prepare clinical, treatment and even practice guidelines, she said.I dont think weve been slow to provide that information. In fact, if anything, I think the RACGP and health authorities have been excellent.That said, Associate Professor Kotsirilos says it is imperative GPs are provided with more detailed information when it comes to specific clinical guidelines on helping manage potential long-term effects, such as the hypercoagulable state seen in some patients.We clearly do need better and quicker clinical guidelines for us to access, she said.It is important for GPs to know the best evidence-based treatments in those situations from a long-term perspective.A new article, published in The BMJ on 11 August, explores management of post-acute issues in COVID-19 patients; though the authors acknowledge there are not yet definitive, evidence-based recommendations for management.We therefore used a pragmatic approach based on published studies on SARS and MERS, early editorials and consensus based guidance on COVID-19, a living systematic review, early reports of telerehabilitation (support and exercise via video link), and our own clinical experience, they wrote.According to the article, which is directed at primary care practitioners, approximately 10% of people remain unwell beyond three weeks after diagnosis with COVID-19.Post-acute COVID-19 long COVID seems to be a multi-system disease, sometimes occurring after a relatively mild acute illness, the authors wrote.They say such patients can broadly be divided into those who may have serious sequelae, such as thromboembolic complications, and those with a non-specific clinical picture, mainly characterised by symptoms such as fatigue and breathlessness.The authors define long-COVID as extending beyond three weeks from the onset of first symptoms, while chronic-COVID is defined as extending beyond 12 weeks.The authors list the symptoms of post-acute COVID-19 as:

On the other hand, severe breathlessness may require urgent referral. The following management principles apply:

Associate Professor Vicki Kotsirilos says clinical guidelines are needed to help GPs manage patients with post-acute symptoms of this infection.

FatigueFatigue is a common complaint following infection with COVID-19.It has also been called the most common and debilitating symptom in [ICU] survivors.A letter to the editor published in Medical Hypotheses on 27 June highlights the potential for a post-viral syndrome to manifest following COVID-19.After the acute SARS episode some patients, many of whom were healthcare workers, went on to develop a chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME)-like illness, which nearly 20months on prevented them returning to work, the authors of the letter wrote.We propose that once an acute COVID-19 infection has been overcome, a subgroup of remitted patients are likely to experience long-term adverse effects resembling CFS/ME symptomatology such as persistent fatigue, diffuse myalgia, depressive symptoms, and non-restorative sleep.The authors of the BMJ article say they found no published evidence on the efficacy of either pharmacological or non-pharmacological interventions on fatigue after COVID-19.Associate Professor Kotsirilos says she would advise patients experiencing fatigue to address lifestyle and behavioural factors.Ensuring that they eat well, that they rest, theyre cared for by other people, go to bed early for a good nights sleep and a graded exercise program, she said. It would be just like [management strategies for] patients suffering post-viral fatigue.Chest painThis is another common symptom after acute COVID-19, and clinical assessment should follow similar principles to that for any chest pain.Where the diagnosis is uncertain, or the patient is acutely unwell, urgent cardiology referral may be needed for specialist assessment and investigations (including echocardiography, computed tomography of the chest, or cardiac magnetic resonance imaging), the BMJ authors wrote.Ventricular dysfunctionThe authors advise intense cardiovascular exercise must be avoided for three months in all patients after myocarditis or pericarditis.Meanwhile, athletes are advised to take 36 months of complete rest from cardiovascular training followed by specialist follow-up.ThromboembolismIt is now recognised that COVID-19 can cause a hypercoagulable state with increased risk of thromboembolic events.The authors say many hospitalised patients receive prophylactic anticoagulation.Recommendations for anticoagulation after discharge vary, but higher risk patients are typically discharged from hospital with 10 days of extended thromboprophylaxis, they wrote.If the patient has been diagnosed with a thrombotic episode, anticoagulation and further investigation and monitoring should follow standard guidelines.It is not known how long patients remain hypercoagulable following acute COVID-19.Associate Professor Kotsirilos would like further detailed information for GPs on this topic, including whether the best anticoagulant in this situation is warfarin or another blood thinner, such as low-dose aspirin.That is important for GPs to know, she said.Clinical guidelines are required to help us keep up-to-date with evidence-based appropriate treatments such as the role of blood thinners when to prescribe them and for how long.Neurological sequelaePatients with serious complications such as stroke, seizures or encephalitis should be referred to a neurologist.Meanwhile, non-specific symptoms such as headaches, dizziness and brain fog require supportive management and symptom monitoring.Brain fog is a particularly common symptom reported by patients who describe themselves as long-haulers.Associate Professor Kotsirilos says measures that can help a patient manage fatigue are also applicable for brain fog.Brain fog has been seen with other post-viral chronic fatigue syndromes, she said.With brain fog, its all about resting, avoiding the computer, letting the head or brain rest, not returning to work too quickly, exercise especially outdoors for fresh air but gradually.Other measures include ensuring adequate sleep, reducing stress and eating well.Mental healthWhile a minority of patients may benefit from referral to mental health services, it is important not to pathologise the majority, the authors wrote.Patient organisations emphasise wellbeing, mindfulness, social connection, self-care (including diet and hydration), peer support, and symptom control.Associate Professor Kotsirilos agrees these measures can assist with mental health issues. However, she says regular check-ins with a GP and a mental health care plan may also be important if patients are not coping.Holistic management of the patientAssociate Professor Kotsirilos believes GPs are ideally placed to help manage COVID-19 patients with post-acute issues.When patients have suffered from COVID-19 infection and are suffering long-term effects like chronic fatigue, GPs are in a great position to validate their symptoms, reassure them, explain to them that it is a new disease, were only just coming to understand it, but it is common to get post-viral fatigue, brain fog and other symptoms, she said.GPs play an important role in helping patients make a full recovery post COVID-19 infection.She says GPs can also use this opportunity to discuss lifestyle measures, exercise, reducing stress and avoiding harmful substances like excessive alcohol and smoking.The BMJ authors agree primary care practitioners are in an ideal position to ensure ongoing patient care for those with post-acute symptoms of COVID-19.From the limited current evidence, we anticipate that many patients whose COVID-19 illness is prolonged will recover without specialist input through a holistic and paced approach, they wrote.GPs can also offer their patients much-needed reassurance throughout this process.Patients, many of whom were young and fit before their illness, have described being dismissed or treated as hypochondriacs by health professionals, the authors wrote.In these uncertain times, one key role that the primary care practitioner can play is that of witness, honouring the story of the patient whose protracted recovery was unexpected, alarming, and does not make sense.Log in below to join the conversation.

The Spread of ‘Stranger Than We Can Think’ – SFGate

Posted: August 19, 2020 at 8:53 am

By Deepak Chopra,TM MD and Menas C. Kafatos, PhD

As we go about everyday life, we are embedded in a mystery no one has ever solved. The mystery was voiced by one of the most brilliant quantum pioneers, Werner Heisenberg: Not only is the Universe stranger than we think, it is stranger than we can think. (There are variants of the quote that use reality for universe, and the remark has also been attributed to other famous scientists, but the gist is always the same.)

If we take this remark seriously, it turns out to be truer today than it was in 1900 when the quantum revolution began and the revolutionary new theory of quantum mechanics was put together. How can reality be stranger than we could possibly think? Look at the framework of your life. You pick up your morning coffee, and instantly you are acting in space and time. Your perception of the cup in your hand depends upon the five senses as communicated through the brain. You can think about anything you fancy as you sip your coffee.

These might not seem so mysterious, but there is one mystery after another nested inside everyday experience. Science can reach no consensus on the following:

Where did time come from? Why do properties of physical objects have their origin in invisible waves of probability of observation? Where does a thought come from? How did matter transform into mind? Is consciousness solely a human trait or is it everywhere in the universe?

The pioneers of quantum physics werent the first to ask such questions, but quantum physics got to the nub of how the physical universe is constructed. Everything in existence emerges from ripples in the quantum field, and underlying these ripples is an invisible or virtual domain that goes beyond spacetime, matter, and energy. In the virtual domain, the universe and everything in it is a field of infinite possibilities, and yet the virtual domain cannot be observed directly. As a result, contemporary physics can take us to the horizon of reality, the womb of creation, but it cannot cross the boundary between us and our source of existence.

Almost all the recent models that have gained popularity, including superstrings, the multiverse, and dark matter and energy, exist in so-called mathematical space, or Hilbert space, in recognition that they are not going to yield direct empirical evidence that can be perceived with our senses. Astrophysics had already gotten used to the fact that just 4% of the created universe is accounted for by the matter and energy visible to the eye or to telescopes. With dark matter and energy added in, most of what we see is not really what the universe consists of.

Leaving the technicalities aside, it has become far more difficult to foresee that the human mind can fully comprehend the nature of reality when so many crucial aspects are beyond the setup that our brains can grasp. The thinking mind needs the brain in order to operate, and the brain is a creation in spacetime consisting of matter and energy, that are in spacetime. We wear mind-made manacles. When this fact dawned on the late Stephen Hawking, he ruefully conceded that scientific models might no longer describe reality in any reliable or complete way.

When we discussed these issues in our book, You Are the Universe, the title reflected another approach entirely. Instead of founding the universe on physical things, however small, or even ripples in the quantum field, which are knowable only through advanced mathematics, reality can be grounded in experience. Everything we call real is an experience in consciousness, including the experience of doing science. Mathematics is a very refined, complex language, but there is no language, simple or complex, without consciousness.

The vast majority of scientists will continue to engage in experimentation and theoretical modeling without this venture into metaphysics, which is a no-no word in science (a famous put down when things get to speculative is Shut up and calculate). But it was quantum physics that brought the mystery of reality into the laboratory in modern terms, even though Plato and Aristotle also wondered about what is real.

A younger generation has proved more open-minded, and a growing cadre of cosmologists now hold to the notion of panpsychism, which holds that mind is built into reality from the start. This is a huge turn-around from the view that mind evolved out of matter here on Earth as a unique creation. The fact is that nobody in the physicalist camp could explain how atoms and molecules learned to thinkcreating mind out of matter was dead on arrival, even though the vast majority of scientists still hold on to this view as an assumption or superstition.

Ironically, to say that reality is stranger than we can think isnt confined to the queer behavior of atoms and subatomic particles. You cannot think about consciousness, either, any more than the eye can see itself or the brain know that it exists (without cutting through the skull to seethe brain from the outside). A fish cannot know that water is wet unless it jumps out of the sea and splashes back down again. We cannot think about consciousness without a place to stand outside consciousness, and such a place doesnt exist in the entire cosmos.

The source of space isnt inside space; the source of time isnt in time. Likewise, the source of mind isnt inside the mind. The ceaseless stream of sensations, images, feelings, and thoughts that run through your mind are the products of consciousness. Consciousness itself has no location. It is infinite, without dimensions in space and time, unborn and undying. Can you really think about such a thing as consciousness? And yet you know without a doubt that you are conscious. This is what allows us to make peace with reality being too strange to think about.

We can simply drop the strange part. Reality can be founded on knowing that you exist and that you are aware. Existence is consciousness. If science is dedicated to the simplest, most complete explanation of things, existence = consciousness is the simplest and most complete explanation. There is no need for religious or spiritual beliefs in order to accept this foundation for reality, since it is based on what science has arrived at. By removing our outdated allegiance to things existing independently of consciousness, the basis of reality can be seen clearly. In our everyday life we navigate with existence and consciousness at our side, indivisible, secure, inviolate, and unchallengeable. A whole new future may spring from accepting this simple but awe-inspiring fact.

Acupuncture shown to regulate inflammation in mice – BioWorld Online

Posted: August 19, 2020 at 8:53 am

A Sino-U.S. collaborative study has demonstrated that acupuncture regulates inflammation by activating pro- or anti-inflammatory signaling pathways, while mitigating cytokine storms in mice with systemic inflammation, the study authors reported in the Aug. 12, 2020, edition of Neuron.

The study also found that the acupuncture site, intensity and timing determined how it affected response, which has important implications for acupuncture use in inflammatory diseases and as adjunctive cancer therapy.

Acupuncture was further shown to influence how mice coped with the aberrant immune system reaction of cytokine storm due to rapid excessive release of pro-inflammatory cytokines.

Our study provides an insight into how acupuncture can drive distinct autonomic pathways and modulate inflammation in acupoint-, stimulation intensity- and disease state-dependent manners, said study leader Qiufu Ma, a professor in the Dana Farber Cancer Institute and the Department of Neurobiology at Harvard Medical School.

Cytokine storms are a characteristic of inflammatory diseases, notably bacterial or viral infections causing sepsis, an organ-damaging, often-fatal inflammatory response.

Cytokine storms can also be caused by excessive inflammatory responses to traumatic tissue injury, some surgeries, and cancer immunotherapies such as immune checkpoint inhibition, but currently there are no FDA-approved treatments for severe cytokine storms, noted Ma.

For cancer patients receiving immunotherapy who develop inflammatory side effects, milder symptoms might be relieved by corticosteroids, which have their own side effects, he said.

In COVID-19 patients, early pilot studies have suggested using an antibody against the cytokine, interleukin-6 (IL-6), but larger clinical trials are needed to confirm the efficacy and safety of this approach, he told BioWorld.

A traditional Chinese medicine technique, acupuncture has become increasingly integrated into Western medicine, particularly for treating chronic pain and gastrointestinal disorders.

It involves mechanical stimulation of acupoints, supposedly triggering nerve signaling and affecting the function of internal organs corresponding to those acupoints, but acupunctures basic underlying mechanisms have not been fully elucidated.

In their new study, Ma and his research team investigated the use of electroacupuncture stimulation (ES), in which ultra-thin electrodes offer better control of stimulation intensity than traditional needles.

The researchers investigated two cell types secreting the neurotransmitters known to be important inflammatory mediators: adrenal gland chromaffin cells, the main producers of adrenaline, noradrenaline (NA) and dopamine, and peripheral NA neurons.

To determine the precise role these cells play in inflammatory responses, the researchers used a novel genetic tool to ablate chromaffin cells or NA neurons.

We genetically introduced the human diphtheria toxin receptor (DTR) selectively to molecularly defined sympathetic cells, such as those marked by expression of neuropeptide Y (NPY), explained Ma.

Injecting a modified diphtheria toxin that does not cross the brain-blood barrier can selectively ablate DTR-expressing cells, creating mice lacking both NPY-expressing chromaffin cells and NA neurons, or those with a more selective ablation of NPY-expressing chromaffin cells via injecting low-dose toxin only into the adrenal gland.

That allowed inflammatory response comparison in mice with and without those cells, to determine their role in modulating inflammation. The markedly different responses then identified those cells as key regulators of inflammation.

Hind-limb administration of low-intensity ES to mice with a bacterial toxin-induced cytokine storm was shown to activate the vagus-adrenal axis, inducing dopamine secretion from chromaffin cells.

We used the induction of a neuronal activation marker to show that low-intensity ES activated hind-brain vagal efferent neurons, which are known to innervate thoracic and visceral organs and tissues, said Ma.

We then showed that low-intensity ES could reduce cytokine storms and promote survival, and that these ES effects were lost in mice with transected vagal efferents or in those with ablation of NPY-expressing adrenal chromaffin cells, suggesting involvement of the vagal-adrenal anti-inflammatory axis.

Specifically, treated animals had more than 50% reductions in the cytokines, tumor necrosis factor-alpha (TNF-a), IL-6 and IL-1b, than untreated controls, and prolonged survival rates of 60% vs. 20%, respectively.

In addition, the vagus-adrenal axis was shown to be activated by hind-limb ES, but not by that using abdominal acupoints, demonstrating the importance of acupoint selectivity in driving specific anti-inflammatory pathways.

Treatment timing was also found to be critical, with high-intensity abdominal stimulation producing markedly different outcomes, depending on when treatment occurred.

For example, animals treated before developing cytokine storm had lower levels of inflammation during subsequent disease and their survival increased from a range of 20% to 30% to a range of 70% to 80%.

Conversely, those treated after disease onset and during the cytokine storm peak experienced worse inflammation and more severe disease.

Together, those findings suggest that ES could be a versatile treatment modality, from adjunct therapy for sepsis to targeted treatment of site-specific inflammation, such as in inflammatory intestinal diseases.

Acupuncture might also help modulate inflammation due to cancer immune therapy, which can trigger cytokine storms, and is currently used in integrative cancer treatment to help patients tolerate treatment side effects.

However, before considering any therapeutic use, those findings must be further confirmed in animals and humans, optimal ES parameters must be defined and its safety established.

Safety

High-intensity ES can drive spinal-splenic noradrenergic sympathetic neuronal pathway, potently reducing inflammation if performed before cytokine storm induction, said Ma.

However, after the first cytokine storm wave has peaked, high-intensity ES can exacerbate inflammation and increase fatality rates, due to altered NA receptor profiles in immune cells switching from anti-inflammatory to pro-inflammatory dominance.

As such, high intensity ES may be associated with unforeseen safety issues, but fortunately low intensity ES is sufficient to drive the vagal-adrenal axis and safely attenuate inflammation in a disease state-independent manner, Ma said.

In the future, he said, inflammation modulation needs to be fine-tuned, since excessive suppression could reduce the ability of the immune system to fight with infection, necessitating future human studies to optimize stimulation parameters.

Yoga Shown to Improve Anxiety, Study Finds | NYU Langone News – NYU Langone Health

Posted: August 19, 2020 at 8:53 am

Yoga improves symptoms of generalized anxiety disorder, a condition with chronic nervousness and worry, suggesting the popular practice may be helpful in treating anxiety in some people.

Led by researchers at NYU Grossman School of Medicine, a new study found that yoga was significantly more effective for generalized anxiety disorder than standard education on stress management, but not as effective as cognitive behavioral therapy (CBT), the gold standard form of structured talk therapy that helps patients identify negative thinking for better responses to challenges.

Generalized anxiety disorder is a very common condition, yet many are not willing or able to access evidence-based treatments, says lead study author Naomi M. Simon, MD, a professor in the Department of Psychiatry at NYU Langone Health. Our findings demonstrate that yoga, which is safe and widely available, can improve symptoms for some people with this disorder and could be a valuable tool in an overall treatment plan.

For the study, 226 men and women with generalized anxiety disorder were randomly assigned to 3 groupsCBT, Kundalini yoga, or stress management education, a standardized control technique.

After three months, both CBT and yoga were found to be significantly more effective for anxiety than stress management. Specifically, 54 percent of those who practiced yoga met response criteria for meaningfully improved symptoms compared with 33 percent in the stress education group. Of those treated with CBT, 71 percent met these symptom improvement criteria.

However, after six months of follow-up, the CBT response remained significantly better than stress education (the control therapy), while yoga was no longer significantly better, suggesting CBT may have more robust, longer-lasting anxiety-reducing effects. The results were published online August 12 in JAMA Psychiatry.

The study involved an evidence-based protocol for CBT treatment of generalized anxiety disorder, including psychoeducation, cognitive interventions (focused on identifying and adapting maladaptive thoughts and worrying), and muscle relaxation techniques.

Kundalini yoga included physical postures, breathing techniques, relaxation exercises, yoga theory, and meditation and mindfulness practice.

The stress management education control group received lectures about the physiological, psychological, and medical effects of stress, as well as the antianxiety effects of lifestyle behaviors, such as reducing alcohol and smoking, and the importance of exercise and a healthy diet. Homework consisted of listening to educational material about stress, nutrition, and lifestyle.

Each treatment was administered in groups of 3 to 6 participants, over weekly 2-hour sessions for 12 weeks with 20 minutes of daily homework assigned.

According to researchers, generalized anxiety disorder is a common, impairing, and undertreated condition, currently affecting an estimated 6.8 million Americans. While most people feel anxious from time to time, it is considered a disorder when worrying becomes excessive and interferes with day-to-day life. CBT is considered the gold standard first-line treatment. Medications, including antidepressants and sometimes benzodiazepines, may also be used. Yet, not everyone is willing to take medication, which can have adverse side effects, and there are challenges with accessing CBT for many, including lack of access to trained therapists and long waitlists.

Many people already seek complementary and alternative interventions, including yoga, to treat anxiety, says Dr. Simon. This study suggests that at least short-term there is significant value for people with generalized anxiety disorder to give yoga a try to see if it works for them. Yoga is well-tolerated, easily accessible, and has a number of health benefits.

According to Dr. Simon, future research should aim to understand who is most likely to benefit from yoga for generalized anxiety disorder to help providers better personalize treatment recommendations.

We need more options to treat anxiety because different people will respond to different interventions, and having more options can help overcome barriers to care, she says. Having a range of effective treatments can increase the likelihood people with anxiety will be willing to engage in evidence-based care.

Along with Dr. Simon, other authors of this study are Stefan G. Hofmann of Boston University; David Rosenfield at Southern Methodist University in Dallas; Susanne S. Hoeppner and Eric Bui of Massachusetts General Hospital, Harvard Medical School in Boston; Elizabeth A. Hoge of Georgetown University Medical Center in Washington, D.C.; and Sat Bir S. Khalsa of Brigham and Womens Hospital, Harvard Medical School in Boston.

Funding for the work came from the National Center for Complementary and Integrative Health grants R01 AT007258 and R01 AT007257 to Dr. Simon and Dr. Hofmann.

Some Coronavirus Patients Are Reporting Symptoms That Last Months. Nobody Knows Exactly How to Treat Them – TIME

Posted: August 19, 2020 at 8:53 am

Kayla Brim laughed when she learned it could take 10 days to get her COVID-19 test results back. I thought, Okay, well, within 10 days I should be fine, she remembers.

That was on July 2. More than a month later, Brim is still far from fine.

Prior to the pandemic, the 28-year-old from Caldwell, Idaho, juggled homeschooling her two kids with her work as a makeup artistshe was supposed to open her own salon in July. Now, she suffers daily from shortness of breath, exhaustion, excruciating headaches, brain fog, neuropathy, high blood pressure and loss of taste and smell. She feels like a little old lady, completely knocked out by simple tasks like making lunch for her children. Shes working just enough to help pay the bills and the lease on her empty salon, but she has no idea when shell be able to work full-time again, and no idea how she and her husband will manage financially if she cant. Half of my day is spent trying to sleep, and the other half of it is trying to pretend like Im okayand I dont know when Ill be okay, Brim says.

This is long-haul COVID-19. Even young, healthy people can become long-haulers (as many call themselves), left unable to work, lead a normal life or, some days, get out of bed. The consequences for each individual can be devastatingand at scale, theyre staggering. Over time, long-haul coronavirus may force hundreds of thousands of people out of work and into doctors offices, shouldering the double burden of lost wages and hefty medical bills for the indeterminate future. To treat them, the health care system may have to stretch already-thin resources to the breaking point.

Its going to be an impending tsunami of patientson top of all the [usual] chronic care that we do, says Dr. Zijian Chen, medical director of the Center for Post-COVID Care at New York Citys Mount Sinai Health System, one of the countrys only clinics devoted to caring for patients in the aftermath of coronavirus infection. At some point it becomes very unsustainablemeaning, the system will collapse.

When most people think of COVID-19, they imagine two possibilities: a flu-like illness that clears on its own, or a life-threatening condition that requires ventilation and a hospital stay. Its not hard to see how the latter scenario leads to long-term damage. Mechanical ventilation is incredibly hard on the lungs, and days or weeks spent sedated in a hospital bed can sap physical and mental strength. In a small study published in 2011, nearly all the participants who needed intensive treatment for a severe lung injury reported decreased physical ability and quality of life five years after leaving the hospital. Some took years to return to work. Hospitalized coronavirus patients may face a similar fate.

But with COVID-19, its not just the sickest who face a long road back. A July 24 report from the U.S. Centers for Disease Control and Prevention (CDC) found that, out of about 300 non-hospitalized but symptomatic COVID-19 patients, 35% were still experiencing symptoms like coughing, shortness of breath and fatigue up to three weeks after diagnosis. (By contrast, more than 90% of non-hospitalized influenza patients fully recover within two weeks.) Recovery from COVID-19 can be a drawn-out process for patients of all ages, genders and prior levels of health, potentially leading to prolonged absence from work, studies, or other activities, the report noted.

The CDCs surveyors only checked up on people a few weeks after they tested positive for coronavirus, but emerging evidence suggests a large subset of patients are sick for months, not just weeks, on end. Dr. Michael Peluso, who is studying long-term COVID-19 outcomes at the University of California, San Francisco, says about 20% of his research participants are still sick between one and four months after diagnosis.

Kayla Brim with her family, outside their home in Caldwell, Idaho, on Aug. 11. Brim has been sick with COVID-19 since early July.

The implications of that problem are enormous. If even 10% of the more than 5 million (and counting) confirmed COVID-19 patients in the U.S. suffer symptoms that last this long, half a million people are already or could soon become chronically ill for the foreseeable future.

When Mount Sinai opened its Post-COVID Center in May, the hospital advertised it as the first in the country; since then, a handful of others have opened in states including Colorado, Indiana and Illinois. Mount Sinais clinic was modeled after the practice the hospital opened to treat survivors of the 9/11 terrorist attacks. Its very similar. Its a new group, and they need special care, Chen says. The biggest difference, he says, is the size of the group. Significantly more people have survived COVID-19 than were directly affected by 9/11. Mount Sinai has only scratched the surface of that demand, treating about 300 people so far. The wait time for new patients extends into October.

The challenge for doctors like Chen is that nobody really knows why long-haul COVID-19 happens, let alone how to treat it. Other viral diseases with long-term symptoms, such as HIV/AIDS, offer some clues, but every day in the clinic is essentially uncharted territory. One hypothesis is that the virus persists in the body in some form, causing continuing problems. Another is that coronavirus pushes the immune system into overdrive, and it stays revving even after the acute infection passes. But at this point, its not clear which theory, if either, is right, or why certain patients recover in days and others suffer for months, Peluso says.

Plus, just as theres huge variation in acute COVID-19 symptoms, not all long-term patients have the same issues. A researcher from the Indiana University School of Medicine in July surveyed 1,500 long-haulers from Survivor Corps, an online COVID-19 support group. They reported almost 100 distinct symptoms, from anxiety and fatigue to muscle cramps and breathing problems. A JAMA Cardiology study published in July suggested many recently recovered patients had lingering heart abnormalities, with inflammation the most common.

Some long-term COVID-19 patients have abnormal test results or damage to a specific organ, giving doctors clues as to how they should be treated. But for others, theres no obvious reason for their suffering, making treatment an educated guessing game. We dont know why they [still] have symptoms. We dont know if our techniques are working, Chen says. We dont know if theyre going to get back to 100%, or 90%, or 80%.

With little evidence, some doctors turn coronavirus long-haulers away or try to convince them their symptoms are psychological. Marcus Tomoff, a 28-year-old in Tampa, Fla. who is in his second month of debilitating fatigue, back and chest pain, nausea and anxiety after a bout of coronavirus, says he hasnt been taken seriously by friends or even his doctors. Several times Ive cried in front of my doctors and they say, You need to deal with this, youre young, he says.

The haphazard testing system in the U.S. has further complicated patients searches for care. Mount Sinais Post-COVID Center, for example, only accepts patients who tested positive for COVID-19 or its antibodies, and Chen fears potential patients who couldnt get tested or got false-negative results may be falling through the cracks. The best he can do right now is refer them to specialists and hope they find a doctor who can help.

For 46-year-old Andrea Ceresa, getting better is a full-time jobminus the paycheck. Ceresa had to stop working as a New Jersey dental office manager after she got sick in mid-April with what she and her doctors believe was COVID-19. (She tested negative for the virus and its antibodies, but her doctors think they were false negatives.) More than 100 days later, shes in regular contact with her primary care physician, an integrative care doctor and a rotating cast of specialists who she hopes can treat her lingering gastrointestinal problems, hearing and vision issues, weight and hair loss, heart palpitations, migraines, brain fog, neuropathy, fatigue, nausea and anxiety. She finally got an appointment at a post-COVID program after weeks of waiting, but shes mostly been left to cobble together her own care team.

Ceresa has paid for her own health insurance through the federal COBRA program since she stopped working, which has put her in a precarious financial state. I have a stack of bills and I just am starting to open them now, she says. Im definitely, at this point, going to be in the hole thousands of dollars. Im collecting unemployment. I know Im going to have to go on disability. Even then, she says, it may not be enough to pay her bills.

There may soon be a lot of patients like Ceresa, says Dr. Bhakti Patel, a pulmonologist at University of Chicago Medicine who studies the long-term effects of critical care. Patel says patients with long-term issues after surviving coronavirus may face a number of obstacles. Patients who remain too sick to return to work (or who are unemployed due to the economic climate) may lose employer-sponsored health insurance at the moment they need it most. Younger patients who do not qualify for Medicare but need public insurance will likely be funneled toward Medicaid, which Patel says is already over-stretched. The services long-haul coronavirus patients may needlike physical therapy and mental health carecan be difficult to access, especially via public insurance networks like Medicaid, Patel says. That bottleneck will only get worse if more people need public aid.

As patients with an emerging disease, long-haulers also need an intensity of outpatient care and expertise, that goes beyond what the average primary care physician can offer, Peluso says. Very few doctors are experienced in treating long-haul symptomsand even among those who are, experienced is a relative term. This wasnt a specialty three months ago, says Chen.

People who cant get into a dedicated post-COVID program may need to try a slew of specialists before they find one who can help, an expensive and tiring game of trial-and-error. (Thats assuming patients can get appointments with specialists like pulmonologists and neurologists, who are often few and far between outside of densely populated areas.) The sickest long-haul patients may also require pricey and difficult-to-access rehab or in-home care, on top of other medical costs. If a family member has to give up work to become a caregiver, that can also have serious economic consequences.

Some long-haulers will likely have to file for disability benefits, a byzantine system of its own thats at risk of becoming overwhelmed. From 2008 to 2017, only about a third of people who applied for disabled-worker benefits in the U.S. were initially approved, according to Social Security Administration (SSA) data. It can be especially difficult for patients without a clear diagnosis or cause of illness, since SSA requires claimants to provide objective medical evidence of an impairment.

With few other resources available, thousands of long-haulers have sought help from virtual support groups like Survivor Corps and Body Politic, where members talk about their symptoms and celebrate signs of recovery. Programs like COVID Bootcamp 101, an online rehab series run by the nonprofit Pulmonary Wellness Foundation, are also trying to fill gaps in care. The scientific community is doing its best to catch up, but Chen says the government may need to help develop long-term solutions that address the economic consequences of long-term coronavirus symptoms, like a medical safety net program (as it has done for HIV/AIDS patients) or financial assistance for COVID-19 patients (as it did for 9/11 survivors).

Without clear answers about what happens next, all doctors can offer the public is yet another plea to take coronavirus seriouslybecause right now, the only surefire way not to become a long-hauler is to not get COVID-19 at all.

That doesnt help people like Ceresa, though. After more than 100 days of feeling sick, Cersa says shes still baffled this happened to her, an active and healthy woman whos been a vegan for decades. She stayed home all April except for a couple trips to the grocery store and still had her life destroyed by the virus. She cant work, sing in her band or plan her wedding after getting engaged a few weeks before the pandemic hit. She tries to comfort herself by thinking about ways it could be worseit could be cancerbut the truth is, things are bad. You try to be hopeful and think somehow, miraculously, youre going to be better, and it doesnt happen, she says. I cant imagine living like this for another day, let alone the rest of my life.

At this point, no one knows if shell have to.

Israel and UAE team up on stem cell therapy research for COVID-19 – UPI News

Posted: August 18, 2020 at 12:50 am

Aug. 17 (UPI) -- Israel and United Arab Emirates stem cell therapy companies signed an agreement Monday to collaborate on researching potential treatment for COVID-19.

The accord between Israel's Pluristem Therapeutics and UAE's Abu Dhabi Stem Cells Center aims to capitalize on each company's expertise to develop therapies and regenerative medicines for the treatment of severe diseases including COVID-19, according to a joint statement.

Both companies have been treating COVID-19 patients with stem cells.

Pluristem has been treating COVID-19 patients with a placenta-based stem cell therapy. The U.S. Food and Drug Administration cleared the Israel stem cell therapy company in May for a Phase II study of the treatment for severe COVID-19 cases. Preliminary results released in May from compassionate-use programs in Israel and the United States were promising, showing that 75 percent of participants no longer needed mechanical ventilation within 28 days.

The Abu Dhabi Stem Cells Center has started a therapy that returns blood-based stem cells back into the patient's lungs as a fine mist through a nebulizer.

"We are extremely proud to partner with our colleagues at the ADSCC by sharing knowledge and expertise that we believe will advance healthcare within and across our borders," Pluristem CEO and President Yaky Yanay said in the statement.

The ADSCC's General Manager Dr. Yendry Ventura also commented on the deal in the statement.

"Pluristem is a major player in the cell therapy field with years of experience, a unique platform and robust clinical pipeline," Ventura said. "We are excited to join forces and to promote the research and development of cell therapies for the best of the patients and the human society as a whole."

The deal is the second cross-border agreement since President Donald Trump brokered a deal to normalize ties between Israel and the UAE. It follows a cross-border deal on Sunday between UAE-based APEX National Investment and Israel's TeraGroup to conduct research on the coronavirus.

BREVARD COUNTY MELBOURNE, FLORIDA During last months surgery to address an issue with Brodys joints, Dr. Jeffrey Christiansen of Superior Veterinary Surgical Solutions collected a small amount of Brodys fat.

A laboratory extracted stem cells from the fat sample, which can be used to reduce pain and inflammation and promote healing of the surgical site.

On Friday morning, Brody was brought back to the L3Harris Animal Care Center to receive his first dose of this medication.

Two injections containing about five million stem cells each were delivered directly to Brodys hip joints. To accomplish this, Dr. Christiansen carefully inserted a needle into Brodys hip and drew a small amount of joint fluid to confirm the tip was in the right place, then administered the injection.

A third, less-concentrated injection was delivered intravenously.

We also captured some radiographs to check on Brodys hip condition.

While we wont be able to evaluate the long-term effectiveness of the surgery for quite some time, he appears to be recovering without complication.

Brody woke from the anesthesia and was returned to his habitat. It is normal for animals to experience discomfort and lameness for a few days following stem-cell injections, but Brody is already back to being his normal, energetic self.

We have enough stem cells banked for an additional 15 doses, which will be administered throughout the course of Brodys life as needed.

Quality veterinary care is expensive. Click here to support animal wellness at the Zoo during this financially challenging time.

Researchers find method to regrow cartilage in the joints – Stanford Medical Center Report

Posted: August 18, 2020 at 12:50 am

Damaged cartilage can be treated through a technique called microfracture, in which tiny holes are drilled in the surface of a joint. The microfracture technique prompts the body to create new tissue in the joint, but the new tissue is not much like cartilage.

Microfracture results in what is called fibrocartilage, which is really more like scar tissue than natural cartilage, said Chan. It covers the bone and is better than nothing, but it doesnt have the bounce and elasticity of natural cartilage, and it tends to degrade relatively quickly.

The most recent research arose, in part, through the work of surgeon Matthew Murphy, PhD, a visiting researcher at Stanford who is now at the University of Manchester. I never felt anyone really understood how microfracture really worked, Murphy said. I realized the only way to understand the process was to look at what stem cells are doing after microfracture. Murphy is the lead author on the paper. Chan and Longaker are co-senior authors.

For a long time, Chan said, people assumed that adult cartilage did not regenerate after injury because the tissue did not have many skeletal stem cells that could be activated. Working in a mouse model, the team documented that microfracture did activate skeletal stem cells. Left to their own devices, however, those activated skeletal stem cells regenerated fibrocartilage in the joint.

But what if the healing process after microfracture could be steered toward development of cartilage and away from fibrocartilage? The researchers knew that as bone develops, cells must first go through a cartilage stage before turning into bone. They had the idea that they might encourage the skeletal stem cells in the joint to start along a path toward becoming bone, but stop the process at the cartilage stage.

The researchers used a powerful molecule called bone morphogenetic protein 2 (BMP2) to initiate bone formation after microfracture, but then stopped the process midway with a molecule that blocked another signaling molecule important in bone formation, called vascular endothelial growth factor (VEGF).

What we ended up with was cartilage that is made of the same sort of cells as natural cartilage with comparable mechanical properties, unlike the fibrocartilage that we usually get, Chan said. It also restored mobility to osteoarthritic mice and significantly reduced their pain.

As a proof of principle that this might also work in humans, the researchers transferred human tissue into mice that were bred to not reject the tissue, and were able to show that human skeletal stem cells could be steered toward bone development but stopped at the cartilage stage.

The next stage of research is to conduct similar experiments in larger animals before starting human clinical trials. Murphy points out that because of the difficulty in working with very small mouse joints, there might be some improvements to the system they could make as they move into relatively larger joints.

The first human clinical trials might be for people who have arthritis in their fingers and toes. We might start with small joints, and if that works we would move up to larger joints like knees, Murphy says. Right now, one of the most common surgeries for arthritis in the fingers is to have the bone at the base of the thumb taken out. In such cases we might try this to save the joint, and if it doesnt work we just take out the bone as we would have anyway. Theres a big potential for improvement, and the downside is that we would be back to where we were before.

Longaker points out that one advantage of their discovery is that the main components of a potential therapy are approved as safe and effective by the FDA. BMP2 has already been approved for helping bone heal, and VEGF inhibitors are already used as anti-cancer therapies, Longaker said. This would help speed the approval of any therapy we develop.

Joint replacement surgery has revolutionized how doctors treat arthritis and is very common: By age 80, 1 in 10 people will have a hip replacement and 1 in 20 will have a knee replaced. But such joint replacement is extremely invasive, has a limited lifespan and is performed only after arthritis hits and patients endure lasting pain. The researchers say they can envision a time when people are able to avoid getting arthritis in the first place by rejuvenating their cartilage in their joints before it is badly degraded.

One idea is to follow a Jiffy Lube model of cartilage replenishment, Longaker said. You dont wait for damage to accumulate you go in periodically and use this technique to boost your articular cartilage before you have a problem.

Longaker is the Deane P. and Louise Mitchell Professor in the School of Medicine and co-director of the Institute for Stem Cell Biology and Regenerative Medicine. Chan is a member of the Institute for Stem Cell Biology and Regenerative Medicine and Stanford Immunology.

Other Stanford scientist taking part in the research were professor of pathology Irving Weissman, MD, the Virginia and D. K. Ludwig Professor in Clinical Investigation in Cancer Research; professor of surgery Stuart B. Goodman, MD, the Robert L. and Mary Ellenburg Professor in Surgery; associate professor of orthopaedic surgery Fan Yang, PhD; professor of surgery Derrick C.
