Long Covid Raises Risk of Heart Problems

By Pat Anson, PNN Editor

Headaches, fatigue, shortness of breath, and cognitive problems are common symptoms of Long COVID, a persistent and puzzling illness that can linger for months or years after the initial COVID-19 infection.     

Two new studies being presented at the American College of Cardiology’s Annual Scientific Session suggest that people with Long COVID may also be at risk of long-term cardiovascular problems.

“COVID-19 is more than a simple respiratory disease — it is a syndrome that can affect the heart,” said Joanna Lee, a medical student at David Tvildiani Medical University and scholar at the Global Remote Research Scholars Program (GRRSP). “Clinicians should be aware that cardiac complications can exist and investigate further if a patient complains of these symptoms, even a long time after contracting COVID-19.”

Lee and her colleagues reviewed findings from 11 major studies involving 5.8 million people, in what’s believed to be the largest effort to date to examine cardiovascular complications from long COVID. They found that Long COVID more than doubles a person’s risk of developing cardiac complications compared to a control group.

Researchers did not investigate what caused the association between Long COVID and heart complications, but they suspect that chronic inflammation plays a role. People with Long Covid often have persistently high inflammatory markers – something healthcare providers should be alert to.

“Coordinated efforts among primary care providers, emergency room staff and cardiologists could help with early detection and mitigation of cardiac complications among long COVID patients,” Lee said. “For patients, if you had COVID-19 and you continue to have difficulty breathing or any kind of new heart problems, you should go to the doctor and get it checked out.”

In the second study, researchers at Intermountain Health in Salt Lake City looked at health data for nearly 150,000 patients who tested positive for COVID-19, and found that even those with mild symptoms had significantly higher rates of chest pain six months to a year after the initial infection. But there was no increase in heart attacks or other cardiovascular events.

“While we didn’t see any significant rates of major events like heart attack or stroke in patients who had an initial mild initial infection, we did find chest pains to be a persistent problem, which could be a sign of future cardiovascular complications,” said lead author Heidi May, PhD, a cardiovascular epidemiologist at Intermountain Health. 

A third study, recently published in JAMA Health Forum, supports many of these findings. Researchers at Elevance Health in Indiana compared more than 13,000 Long COVID patients to a control group of 26,000 people without COVID. Those with Long COVID had significantly higher rates of cardiac arrhythmia, blood clots, stroke, coronary artery disease, heart failure, asthma and mortality.

Notably, nearly 3 out of 4 had only mild COVID symptoms and were not hospitalized during the initial infection, suggesting that the health of all COVID patients needs to be monitored long-term.

“From a health policy perspective, these results also indicate a meaningful effect on future health care utilization, and even potential implications for labor force participation,” researchers said.

About one in every five patients infected with COVID-19 develops symptoms of Long COVID. A recent study found that COVID vaccines appear to significantly reduce the risk of getting Long COVID.

The CDC estimates there were 103 million confirmed U.S. cases of COVID-19, resulting in 1.13 million deaths.

Injection of Donor Cells Gives Long-Term Relief from Degenerative Disc Disease

By Pat Anson, PNN Editor

A single injection of cells and fluid derived from human donor tissue was successful long-term in relieving pain and restoring physical function in patients with degenerative disc disease, according to new research presented at the annual meeting of the Society of Interventional Radiology in Phoenix.

The injections, known as viable disc allograft supplementation, encourage cells in damaged discs to regenerate with healthy tissue. Degenerative disc disease is one of the leading causes of chronic lower back pain.

“The significant improvement in pain and function is promising for patients living with chronic low back pain – a condition that can greatly impact a person’s quality of life,” said lead author Douglas Beall, MD, chief of radiology at Clinical Radiology of Oklahoma. “Back pain is the leading cause of limited activity and workplace absenteeism. This treatment may help patients return to a normal activity level for a longer period time.”

Fifty patients participated in the VAST trial, with 46 patients receiving allograft treatment and four receiving saline injections as a placebo. VIVEX Biologics, a regenerative medicine company that processes donated cells and tissue to treat musculoskeletal injuries, wounds and burns, sponsored the study.

After three years, 60 percent of patients who received allograft treatment reported more than 50% improvement in pain and 70% had significant improvement in their function scores. No patients suffered adverse effects.

In healthy patients, discs cushion the spine’s vertebrae, facilitating movement and flexibility. But discs can wear out over time and cause the bones of the spine to rub together and pinch nerves, causing pain and disability. By age 60, most people have at least some disc degeneration.

“Existing treatment for chronic low back pain due to degenerative disc disease is often ineffective or the effects are short-lived,” said Beall, who is a medical consultant for VIVEX. “We need better treatments for this condition since conservative care is not providing the long-term outcomes that patients deserve. Injectable allograft treatment might be the answer for many people.”

Beall says allograft injections could decrease the use of pain medication by patients with chronic lower back pain. The treatment requires no incisions and patients are able to go home on the same day.

Other companies are also developing new injections to treat degenerative disc disease. In clinical trials, Australia-based Mesoblast says injections of its proprietary stem cell product provided long-term relief for people with lower back pain caused by disc disease. The company recently announced the FDA designated its stem cell injection as a Regenerative Medicine Advanced Therapy, which is designed to help speed up its development.   

Injections of an experimental gel developed by ReGelTec also show promise as a treatment for disc disease. The hydrogel is heated before injection to more easily fill cracks and tears in the affected discs. When the gel cools and hardens, it helps restore the disc’s structural integrity.   

Our Bodies Produce Chemicals Similar to THC in Cannabis

By Drs. Prakash and Mitzi Nagarkatti, University of South Carolina

Over the past two decades, a great deal of attention has been given to marijuana – also known as pot or weed. As of early 2023, marijuana has been legalized for recreational use in 21 states and Washington, D.C., and the use of marijuana for medical purposes has grown significantly during the last 20 or so years.

But few people know that the human body naturally produces chemicals that are very similar to delta-9-tetrahydrocannabinol, or THC, the psychoactive compound in marijuana, which comes from the Cannabis sativa plant. These substances are called endocannabinoids, and they’re found across all vertebrate species.

Evolutionarily, the appearance of endocannabinoids in vertebrate animals predates that of Cannabis sativa by about 575 million years.

It is as if the human body has its own version of a marijuana seedling inside, constantly producing small amounts of endocannabinoids.

The similarity of endocannabinoids to THC, and their importance in maintaining human health, have raised significant interest among scientists to further study their role in health and disease, and potentially use them as therapeutic targets to treat human diseases.

THC was first identified in 1964, and is just one of more than 100 compounds found in marijuana that are called cannabinoids.

What Are Endocannabinoids?

Endocannabinoids were not discovered until 1992. Since then, research has revealed that they are critical for many important physiological functions that regulate human health. An imbalance in the production of endocannabinoids, or in the body’s responsiveness to them, can lead to major clinical disorders, including obesity as well as neurodegenerative, cardiovascular and inflammatory diseases.

We are immunologists who have been studying the effects of marijuana cannabinoids and vertebrate endocannabinoids on inflammation and cancer for more than two decades. Research in our laboratory has shown that endocannabinoids regulate inflammation and other immune functions.

A variety of tissues in the body, including brain, muscle, fatty tissue and immune cells, produce small quantities of endocannabinoids. There are two main types of endocannabinoids: anandamide, or AEA, and 2-arachidonoyl glycerol, known as 2-AG. Both of them can activate the body’s cannabinoid receptors, which receive and process chemical signals in cells.

One of these receptors, called CB1, is found predominantly in the brain. The other, called CB2, is found mainly in immune cells. It is primarily through the activation of these two receptors that endocannabinoids control many bodily functions.

The receptors can be compared to a “lock” and the endocannabinoids a “key” that can open the lock and gain entry into the cells. All these endocannabinoid receptors and molecules together are referred to as the endocannabinoid system.

The cannabis plant contains another compound called cannabidiol, or CBD, which has become popular for its medicinal properties. Unlike THC, CBD doesn’t have psychoactive properties because it does not activate CB1 receptors in the brain. Nor does it activate the CB2 receptors, meaning that its action on immune cells is independent of CB2 receptors.

Endocannabinoids Help Us Feel Better

The euphoric “high” feeling that people experience when using marijuana comes from THC activating the CB1 receptors in the brain.

But when endocannabinoids activate CB1 receptors, by comparison, they do not cause a marijuana high. One reason is that the body produces them in smaller quantities than the typical amount of THC in marijuana. The other is that certain enzymes break them down rapidly after they carry out their cellular functions.

However, there is growing evidence that certain activities may release mood-elevating endocannabinoids. Some research suggests that the relaxed, euphoric feeling you get after exercise, called a “runner’s high,” results from the release of endocannabinoids rather than from endorphins, as previously thought.

The endocannabinoids regulate several bodily functions such as sleep, mood, appetite, learning, memory, body temperature, pain, immune functions and fertility. They control some of these functions by regulating nerve cell signaling in the brain. Normally, nerve cells communicate with one another at junctions called synapses. The endocannabinoid system in the brain regulates this communication at synapses, which explains its ability to affect a wide array of bodily functions.

Research in our laboratory has shown that certain cells of the immune system produce endocannabinoids that can regulate inflammation and other immune functions through the activation of CB2 receptors.

In addition, we have shown that endocannabinoids are highly effective in lessening the debilitating effects of autoimmune diseases. These are diseases in which the immune system goes haywire and starts destroying the body’s organs and tissues. Examples include multiple sclerosis, lupus, hepatitis and arthritis.

Chronic Pain Linked to Low Levels of Endocannabinoids

Recent research suggests that migraine, fibromyalgia, irritable bowel syndrome, post-traumatic stress disorder and bipolar disease are all linked to low levels of endocannabinoids.

In a 2022 study, researchers found that a defect in a gene that helps produce endocannabinoids causes early onset of Parkinson’s disease. Another 2022 study linked the same gene defect to other neurological disorders, including developmental delay, poor muscle control and vision problems.

Other research has shown that people with a defective form of CB1 receptors experience increased pain sensitivity such as migraine headaches and suffer from sleep and memory disorders and anxiety.

We believe that the medicinal properties of THC may be linked to the molecule’s ability to compensate for a deficiency or defect in the production or functions of the endocannabinoids.

For example, scientists have found that people who experience certain types of chronic pain may have decreased production of endocannabinoids. People who consume marijuana for medicinal purposes report significant relief from pain. Because the THC in marijuana is the cannabinoid that reduces pain, it may be helping to compensate for the decreased production or functions of endocannabinoids in such patients.

Deciphering the role of endocannabinoids is still an emerging area of health research. Certainly much more research is needed to decipher their role in regulating different functions in the body.

In our view, it will also be important to continue to unravel the relationship between defects in the endocannabinoid system and the development of various diseases and clinical disorders. We think that the answers could hold great promise for the development of new therapies using the body’s own cannabinoids.

FDA Approves Wearable Device for Migraine Prevention

By Pat Anson, PNN Editor

A wearable neuromodulation device has been approved by the Food and Drug Administration as a preventative treatment for migraine. In a recent study, the Nerivio device significantly reduced the number of migraine days per month in patients with episodic and chronic migraine.

Nerivio is worn on the upper arm and controlled by a smartphone app. It uses mild electrical pulses to disrupt pain signals in the brain without the use of drugs. The device has previously received clearance from the FDA as an acute treatment for migraine in adults and children over age 12.

"Nerivio already has a well-established efficacy and safety profile in acute migraine treatment," said Andrew Blumenfeld, MD, Director of the Los Angeles Headache Center and co-author of the study published in the journal Headache. "Effective preventive treatment is key to managing migraine, but it is often underutilized.”

THERANICA IMAGE

The randomized, placebo-controlled trial involved 248 migraine sufferers who used either Nerivio or a placebo device for 45 minutes every other day. Those who used Nerivio experienced a mean reduction of 4 migraine days per month, compared to a reduction of 1.3 days in the placebo group. Participants also experienced statistically significant reductions in the number of days they required acute migraine medication.

“The trial data demonstrates Nerivio can now cover the full treatment spectrum and provide access to migraine prevention and relief, especially for the adolescent population, who have a strong preference for clinically effective, drug-free treatment solutions. With FDA clearance of the device, its availability and potential use for preventive and acute treatment is welcome news for both physicians and patients," Blumenfeld said in a statement.

Like most new migraine treatments, Nerivio can be expensive, with the wholesale price currently listed at $599 for a 12-treatment unit. Out of pocket costs will be less if the device is covered by insurance or if patients enroll in Nerivio’s Patient Savings Program. A prescription is required.

With Nerivio’s new dual-use indication, patients may use the device more often to proactively prevent migraines. To better support existing and new users, the number of treatments per unit is being expanded from 12 to 18 treatments.

The Nerivio app allows patients to customize their treatment, receive reminders for preventive treatment, track their migraine patterns, and share migraine data with their doctor. The app can also leads users through a Guided Intervention of Education and Relaxation, using techniques such as diaphragmatic breathing, muscle relaxation and guided imagery.

Nerivio is made by Theranica, a medical technology company based in Israel, which estimates the device has over 40,000 users in the United States. The company is investigating whether the device may help treat other chronic pain conditions besides migraine.

Are You Suffering from Toxic Stress?

By Ann Marie Gaudon, PNN Columnist

There is no such thing as life without stress. It’s both a physiological and psychological response to a real threat or a perceived one. Stress tends to resolve itself naturally and in a timely way as the situation resolves, but “toxic stress” is different.

Frequent chronic stress, in the absence of adequate support, has harmful and potentially lasting effects on a person’s physical and mental health. It can affect anyone at any age, and no one is immune.

You are at risk for toxic stress when the stress is persistent and severe. You may have multiple stress factors and the body will react to them. One reaction will be that the body’s fight-or-flight, faint-or-freeze response is activated too often or for too long. This results in the release of stress hormones, one of which is cortisol. Long-term heightened levels of cortisol can become dysfunctional, inducing widespread inflammation and pain.

There is a very real biological link between stress, anxiety and pain. Toxic stress makes you more at risk for many types of chronic illness and pain, a dampened immune system, infections, mental health issues, poor emotional regulation skills, and even substance abuse. You can become sick and stay sick.

Toxic stress will also make you more vulnerable to chronic anxiety, which can include panic attacks. You may become hypersensitive to threat and to pain severity. Your behaviour will also likely change, which can mean trouble for relationships. In short, toxic stress will invade every thread of the fabric of your life.

Types of Stress

Stress Buffers

Toxic stress can’t always be avoided – the loss of a beloved one, a nasty divorce, conflict in the home, chronic depression, feelings of betrayal and other life changes are sometimes inevitable.

However, a relationship with an adult who is loving, responsive and stable can help to buffer against the effects of stress and stop it from turning toxic. Other buffers include high levels of social support, consistent nurturing, and confidence in your problem-solving skills are just a few in an umbrella of many.

There are strategies you can do on your own to help buffer yourself against the consequences of toxic stress. Crucially, it is important to focus on what you can control, not what you have no control over. Toxic stress may include factors that are actually beyond your control, leaving you more distressed and overwhelmed, so it’s very important to become aware of the differences.

Write a list of what you can and cannot control. Take the reins on what you are able to, even if it’s as routine as what you’ll eat for dinner each day. Spend your time and energy on things that can improve your situation and can get a handle on. Remember, when we rail against that which we cannot control, that is when our suffering soars.

Healthy Living

Focus on a healthy lifestyle. Toxic stress can easily slide into unhealthy habits such as smoking, too much alcohol, overeating, overworking and the like. You may get temporary relief from them, but in the long-term these poor coping mechanisms will serve to worsen your stress. Eat well, exercise, get outside into nature, and try as best you can to get good sleep while practicing sleep hygiene.

Some people have a tendency to isolate themselves when stressed, yet one of the most protective buffers against toxic stress is support from people who care about you. Never underestimate the power of touch, including deliberate and welcome hugs. Reach out, engage with others, and make plans with others who are close to you. You want to be with adults who are soothing, safe and secure for you.

Find a relaxation technique that helps you lower your stress level. I’m a little different than some, because vigorous exercise is my happy place. Heart-pumping, blood-flowing, rushes of endorphins take my physical pain down and make me feel relaxed.

Alternatively, you might benefit from stillness with mindfulness practice, journalling, yoga or Tai Chi, body scans or progressive muscle relaxation techniques. Find your happy place and go there as often as you are able.

A very wise colleague of mine told me that we need three things to be happy: someone to love, a purpose, and something to look forward to. Go ahead and set goals, and plan for the future.

Toxic stress can have the sufferer believing that things will never improve, which leads to hopelessness and despair. Making plans for the future will give you some direction and purpose, as well as something to look forward to. When a good experience happens, optimism can drop by for a visit to remind you that life won’t always be so challenging.

As always, if you’re really struggling, reach out to a trained professional. We all need help at times in our lives, and one of those times might be when you’re dealing with toxic stress.  Your professional therapist will support you and help you with tools and strategies so that you can in turn support yourself.

DEA to Reimpose ‘Guardrails’ on Telehealth Opioids

By Pat Anson, PNN Editor

The U.S. Drug Enforcement Administration plans to reimpose rules that require doctors to meet face-to-face with patients before they are prescribed opioids and other controlled substances.

The rules were suspended in 2020 in the early stages of the Covid-19 pandemic so that doctors and patients could connect remotely via telehealth – also known as telemedicine --  to get medications prescribed without an in-person meeting.

But when the federal government ends the Covid public health emergency on May 11, the DEA plans to restore “appropriate safeguards” on medications it considers addictive. Patients will still be able to get prescriptions for antibiotics, statins, insulin and other common medications through telehealth, without a physical examination or meeting with a doctor.

“DEA is committed to ensuring that all Americans can access needed medications,” said DEA Administrator Anne Milgram said in a statement.  “The permanent expansion of telemedicine flexibilities would continue greater access to care for patients across the country, while ensuring the safety of patients. DEA is committed to the expansion of telemedicine with guardrails that prevent the online overprescribing of controlled medications that can cause harm.”  

Under the DEA’s proposed rules, Schedule II controlled substances such as oxycodone and hydrocodone cannot be prescribed without first having an in-person meeting. Refills would then be allowed via telehealth.

Other drugs that are classified as Schedule III, IV or V substances – such as Xanax (alprazolam) and Suboxone (buprenorphine) could still be prescribed for 30 days via telehealth, but any refills will require an in-person meeting.

The DEA rules were developed in conjunction with the Department of Health and Human Services (HHS) and the Department of Veterans Affairs. Public comments on the rules can be submitted through the Federal Register by clicking here.

“Improved access to mental health and substance use disorder services through expanded telemedicine flexibilities will save lives,” said HHS Secretary Xavier Becerra. “We still have millions of Americans, particularly those living in rural communities, who face difficulties accessing a doctor or health care provider in-person.”

Drug overdoses rose sharply during the pandemic, with nearly 107,500 drug deaths reported in the 12-month period ending in August, 2022. About 70% of the fatal overdoses involved illicit fentanyl and other street drugs, not prescribed medications.

Why Women Are More Likely to Suffer Migraines

By Pat Anson, PNN Editor

German scientists may have finally proven a link between hormones and migraines, and why women suffer migraines at triple the rate that men do. In studies on animals and humans, researchers found that calcitonin gene-related peptides (CGRPs) increase in females during menstruation.

CGRP is a protein that binds to nerve receptors and dilates blood vessels in the brain, causing migraine pain. Several medications are now on the market that inhibit CGRP, one of the biggest innovations in migraine treatment in decades.

“This elevated level of CGRP following hormonal fluctuations could help to explain why migraine attacks are more likely during menstruation and why migraine attacks gradually decline after menopause,” says Bianca Raffaelli, MD, of Charité – Universitätsmedizin Berlin in Germany. “These results need to be confirmed with larger studies, but we’re hopeful that they will help us better understand the migraine process.”

Raffaelli and her colleagues measured CGRP levels in the blood and tear fluid of 180 women during their menstrual cycles, and found that those who suffer from episodic migraines had significantly higher concentrations of CGRP during menstruation, when estrogen levels are low.

“This means that when estrogen levels drop immediately before the start of a menstrual period, migraine patients release more CGRP,” said Raffaelli, lead author of a study published in the journal Neurology. “This could explain why these patients suffer more migraine attacks just before and during their monthly period.”

In women who take oral contraceptives, there were hardly any fluctuations in their estrogen or CGRP levels. The same was true for postmenopausal women.

“Taking birth control pills and the end of menopause do in fact bring relief for some female migraine patients. But as our study also shows, there are women who suffer from migraine even without any hormonal fluctuations. We suspect that other processes in the body play a role in triggering attacks in those patients. After all, CGRP isn’t the only inflammatory peptide that can cause a migraine attack,” said Raffaelli.

The study also suggests that measuring CGRP levels in tear fluid is feasible and warrants further investigation, because accurately measuring CGRP in the blood is challenging due to its short half-life.

The research team now plans to study how other physical processes are influenced by the menstrual cycle, such as blood vessels and brain function. They also plan to take a closer look at CGRP levels in men of varying age groups.

Migraine affects more than 37 million people in the United States, according to the American Migraine Foundation. In addition to headache pain, migraine can cause nausea, blurriness or visual disturbances, and sensitivity to light and sound.

Staying Active Is Vital for People with Pain

By Joanne Dickson, Edith Cowan University

Chronic pain affects around one in five people and is considered “chronic” when it persists beyond the expected healing time, typically three months or longer.

Along with physical problems, chronic pain can impact a person’s daily activities, employment, lifestyle and mental health.

Doing things you love and having goals are fundamental for wellbeing because they give meaning and purpose. But pain can make doing the activities you enjoy psychologically, physically and/or emotionally very challenging.

Our new research shows the way a person with chronic pain responds to not being able to participate in the activities or goals they value can impact their mental wellbeing – even more so than their pain levels.

We surveyed more than 300 people living chronic pain (that wasn’t related to cancer) about their mental wellbeing, “pain intensity” and how much pain interfered with the everyday pursuits and activities that mattered to them. We differentiated chronic pain from cancer pain due to the differing prognoses and treatments available, and the unique psychological and social factors associated with cancer pain, such as concern about death.

We found pain that disrupted daily life activities, rather than the intensity of the pain, posed the biggest threat to a person’s mental wellbeing.

When pain interferes with a person’s engagement in meaningful daily activities, it causes distress and decreases wellbeing.

The research suggests it’s possible for people to find ways to maintain their mental wellbeing, even when their pain intensity is high, so long as they’re able to maintain aspects of life that are important to them, such as relationships and work.

Find Other Ways to Do Things

We found personal motivational traits – specifically, goal flexibility (adjusting goals in response to changing circumstances and setbacks) and tenacity (persistently striving to achieve a desired goal under difficult circumstances) – were associated with increases in mental wellbeing for people living with chronic pain.

Although flexibility and persistence were both associated with increased mental wellbeing, the capacity to flexibly adjust to setbacks or obstacles had the most significant positive effect in maintaining one’s mental wellbeing.

Flexibility appears to act as a protective factor against the impacts of pain interference on mental wellbeing, to a greater extent than personal tenacity or persistence.

There is often more than one way to modify or adapt an activity when difficulties arise. A walk on the beach with friends, for instance, may be adjusted to meeting at the beach for coffee to fulfil the same goal or value: social connectedness.

Focus on What You Can Do, Not What You Can’t

Psychological processes that can help people to live well in the face of long-term pain have long been overlooked. Research has traditionally focused on unhelpful thought processes that perpetuate or exacerbate mental distress. For example, pain catastrophising and repeated negative self-criticism.

Pain management and mental health are multi-faceted. Previous research has shown pain management should take into account physical factors (age, sleep, injury, disease) and social factors (employment, social support, economic factors).

Our findings add to this body of knowledge. For those living with pain, reappraising and adjusting meaningful life activities and goals, when needed, in response to setbacks or life challenges can help maintain mental wellbeing.

These findings can inform the development of psychological supports for people with chronic pain. In turn, these supports could identify internal strengths, resources, positive coping strategies, self-efficacy, hope and wellbeing – and promote psychological strengths rather than deficits.

Pentagon Declares War on Poppy Seeds

By Pat Anson, PNN Editor

The U.S. Department of Defense is escalating its war against opioids beyond just oxycodone, hydrocodone and other pain medications.

In a February 17 memo, a top Pentagon official warned all military service members that eating foods containing poppy seeds could result in a failed drug test.

“Recent data suggests poppy seeds varieties may have higher codeine contamination than previously reported. Consumption of poppy seed products could cause a codeine positive urinalysis result and undermine the Department’s ability to identify illicit drug use. Out of an abundance of caution, I find protecting Service members and the integrity of the drug testing program requires a warning to avoid poppy seeds,” wrote Gilbert Cisneros, Jr., the Undersecretary of Defense for Personnel and Readiness.

Cisneros did not specific what the “recent data” was or where it came from. Tiny black seeds from the poppy plant – most of which come from Afghanistan -- can become contaminated during harvesting with trace amounts of codeine, morphine and other opiates. Drug users have found they can then use unwashed seeds to make a potent homemade tea to relieve pain.

Given how widely used washed poppy seeds are in muffins, cookies, salad dressings and cosmetics, the threat posed by them may sound rather comical. But some organizations take it very seriously.

The Center for Science in the Public Interest (CSPI) has petitioned the Food and Drug Administration to set a safe threshold for opiate alkaloids in imported poppy seeds, citing a study that claimed 19 people in the U.S. suffered fatal overdoses after ingesting poppy seeds in recent years.

“The time is overdue for the FDA to establish standards that will protect U.S. consumers from ingesting dangerous levels of opiates through the food supply,” said Peter Lurie, MD, President of CSPI.  

In 2019, the Drug Enforcement Administration even classified unwashed poppy seeds as a Schedule II controlled substance, claiming they were “qualitatively similar” to opioid pain medications.

“Unwashed poppy seeds are a danger to the user and their abuse may result in unpredictable outcomes including death,” the DEA said.

Eating poppy seeds could be risky for someone taking a drug test.  A 2020 study found that consuming just few seeds in a muffin or bagel could result in a positive drug test – a finding that could get a patient dismissed by their doctor or an employer refusing to hire a job applicant.

The Pentagon may also be trying to save money with its new directive. Simple urine drug screens performed in a doctor’s office are relatively cheap – and often wrong. False positive results should be confirmed with a mass spectrometry test performed in a laboratory, but those tests usually cost thousands of dollars.  It’s cheaper to just tell military personnel to stop eating bagels.

“The Military Departments are hereby directed to notify Service members to avoid consumption of all poppy seeds to include food products and baked goods containing poppy seeds. Service members are directed to work with their local legal office for any related concerns with urinalysis results,” Cisneros wrote in his memo.

The Pentagon and Department of Veterans Affairs (VA) have long taken a dim view of opioids. In recently updated medical guidelines, the agencies recommend that opioid medications not be used to manage non-cancer chronic pain.   

Limiting Supply of Rx Opioids Fails to Achieve Goals

By Pat Anson, PNN Editor

Limiting initial prescriptions for opioid pain medication to 5-days’ supply did not reduce the rate at which patients in New Jersey transitioned to long-term opioid use, according to a new study at Rutgers University.

In 2017, New Jersey became one of the first states in the country to impose a mandatory 5-day limit on initial opioid prescriptions for acute pain. If a patient needed more, their doctor would have to write a new prescription, enroll them in a pain management program, and counsel them on the risks of opioid addiction.

At least 38 other states adopted similar laws, with the goal of reducing opioid diversion, misuse and overdose. Six years later, there is little evidence that New Jersey’s 5-day limit saved lives or accomplished any of its goals.

“This policy’s apparent failure to achieve its goals illustrates the extreme difficulty of solving healthcare problems by dictating physician behavior,” said senior author Stephen Crystal, PhD, director of the Rutgers Center for Health Services Research.

Crystal and his colleagues analyzed pharmacy data for over 130,000 New Jersey Medicaid patients who were prescribed opioids for the first time between 2014 to 2019. Their findings, recently published in the Journal of General Internal Medicine, show that new opioid prescriptions fell at a monthly rate of less than one percent (0.76%) after the 5-day limit was imposed, a decline that was about half the monthly rate (1.62%) prescriptions were falling before the limit took effect.

Doctors were writing fewer prescriptions for opioids in New Jersey and other states long before limits on the supply were even passed. Opioid prescriptions nationally are now at their lowest level in over 20 years.

“Opioid prescribing was already decreasing before this policy went into effect,” said lead author Peter Treitler, a research project manager at the Rutgers Institute for Health, Health Care Policy and Aging Research. “And so, by the time this New Jersey policy went into effect, it really didn’t change prescribing practices very much, at least in the New Jersey Medicaid population.”

An earlier study by the Rutgers research team found that medically treated overdoses in the Medicaid population tripled in New Jersey after the 5-day limit was imposed. Most of the overdoses involved illicit fentanyl and other street drugs, not prescription opioids.

Less than a third of New Jersey’s overdose survivors were even diagnosed with a chronic pain condition, suggesting the state’s focus on limiting pain medication was misdirected. Most people who overdose suffer from substance abuse disorder, depression or other mental health issues. And most overdoses involve illicit fentanyl and other street drugs, not prescribed medication.

In 2022, there were nearly 2,900 drug deaths in New Jersey – about 30% more than the number that overdosed in 2016, the year before the state’s 5-day limit became law.  

DEA Considers Synthetic THC Illegal

By Pat Anson, PNN Editor

The Drug Enforcement Administration considers a synthetic form of THC — the psychoactive compound in cannabis and hemp — a controlled substance that is illegal under federal law.

Hemp was legalized federally under the 2018 Farm Bill, in part because hemp contains only trace amounts of THC. However, some companies developed a synthetic form of hemp-derived THC — called THC acetate ester (THCO) — to give consumers an intoxicating effect. Because THCO was modeled after the THC found in hemp, they claimed it could be legally sold and consumed.

However, in a recent letter to Rod Kight, an attorney who specializes in cannabis law, the head of the DEA’s Drug & Chemical Evaluation Section said the agency considers delta-8 and delta-9 products containing THCO to be Schedule I controlled substances, which are illegal to sell or possess.

“Delta-9-THCO and delta-8-THCO do not occur naturally in the cannabis plant and can only be obtained synthetically, and therefore do not fall under the definition of hemp. Delta-9-THCO and delta-8-THCO are tetrahydrocannabinols having similar chemical structures and pharmacological activities to those contained in the cannabis plant,” the letter states.

Kight said he’s been telling clients and personal friends that THCO is potentially dangerous.

“Although I do not always agree with the DEA’s view on cannabis matters, I agree with this opinion and, frankly, am not surprised,” he wrote.  “It has always been my view that THCO is a controlled substance under federal law. Although it can be made from cannabinoids from hemp, THCO is not naturally expressed by the hemp plant. It is a laboratory creation that does not occur in nature, at least not from the hemp plant.”

As Kight points out in his blog, the DEA letter does not address delta-8 or delta-9 THC, which are natural and derived from hemp. Although those substances are considered legal at the federal level, over a dozen states have banned products containing them.

In states where they remain legal, delta-8 and 9 are widely available in candy, gummies, cookies, tinctures and beverages. Some companies claim the products have “uniquely potent effects on pain” and other health conditions, even while admitting there is little evidence to support those claims.

The FDA became so alarmed by the profusion of delta-8 and delta-9 THC products — and their marketing to children — that it sent letters to five companies in 2022 warning them to stop making unsubstantiated medical claims.

"These products often include claims that they treat or alleviate the side effects related to a wide variety of diseases or medical disorders, such as cancer, multiple sclerosis, chronic pain, nausea and anxiety," FDA Principal Deputy Commissioner Janet Woodcock, MD, said in a statement. "It is extremely troubling that some of the food products are packaged and labeled in ways that may appeal to children.”

The FDA says it had received over 100 reports of adverse events involving delta-8 THC, with poison control centers reporting over 2,300 cases, including one that involved the death of a child.

Is Your Personal Health Data For Sale?

By Pat Anson, PNN Editor

Many U.S. consumers believe their personal health information is protected under the Health Insurance Portability and Accountability Act (HIPPA), a federal law that requires healthcare providers and insurers not to share a patient’s sensitive health information without their consent or knowledge.

A new study on consumer data brokers and a federal complaint against a popular drug discount service show otherwise, with patient names, social security numbers, email addresses, prescription drug use and other personal information routinely being sold to third parties.

The Duke University study on data brokers focused only on mental health records, but gives you a good idea of what’s available on the open market. When researcher Joanne Kim contacted 37 data brokers asking to buy mental health data on millions of patients, 11 of them offered to sell her the requested data, which included information about whether an individual was being treated for depression, anxiety or insomnia, and if they were prescribed drugs such as Prozac or Zoloft.

The asking price for the information was relatively cheap, with one broker offering data on 10,000 aggregated patient records for $2,000 – or 20 cents per record. The cost was even cheaper if the data was ordered in volume; 435,780 records were available for 6 cents each.

Many of the brokers did not provide Kim with a full explanation about their data or where it came from, making it difficult to determine whether the company was offering “deidentified” information. Some firms openly advertised data that included individual names, addresses, phone numbers and emails. One broker even offered to sell her the IP addresses and browser history of patients.

“This research highlights a largely unregulated data brokerage ecosystem that sells sensitive mental health data in large quantities, with either vague or entirely nonexistent privacy protections,” Kim wrote in her report. “Data brokers are collecting, aggregating, analyzing, circulating, and selling sensitive mental health data on individuals. This comes as a great concern, especially since the firms seem either unaware of or loosely concerned about providing comprehensive privacy protections.”

Due to the stigma associated with mental health problems, Kim says the easy availability of personal health data puts millions of patients at risk of discrimination from employers and insurers, or even theft from scammers who prey on vulnerable populations.

“The nation is in dire need of a comprehensive federal privacy law, and this report recommends that the federal government should also consider generally banning the sale of mental health data on the open market,” she wrote. “Such a law should include provisions that allow consumers to opt out of the collection of their data, gain access to their information, and correct any discrepancies. Furthermore, data brokers should be obligated to be more transparent about their use and exchange of data, as well as have more controls in place for client management.”

One potential “client” that Kim doesn’t mention is law enforcement. In 2020, the Drug Enforcement Administration asked data brokers to submit bids on a potential contract for a surveillance program that would track at least 85% of U.S. prescriptions for opioids and other controlled substances. The DEA was seeking “unlimited access” to this prescription data, including the names of prescribers and pharmacists, types of medication, quantity, dose, refills and forms of payment.

While the contract was never awarded, it remains unclear what the DEA planned to do with the information or if it has found other ways to collect the data.

GoodRx Settlement

Where and how is personal health data collected? It could be as simple as a consumer trying to save money on medications.

The Federal Trade Commission recently reached a $1.5 million settlement with prescription drug discount provider GoodRx for failing to notify consumers that it was selling their information to Facebook, Google and other third parties for advertising purposes.

GoodRx offers considerable savings to patients who enroll in its free drug discount program, and makes money by selling their health and contact information to third parties. For example, according to the FTC complaint, GoodRx shared patient health data with Facebook, which then targeted them with advertisements for specific drugs to treat their health conditions.

“GoodRx’s sharing of personal and health information has revealed highly sensitive and private details about its users, most of whom suffer from chronic health conditions. This has led to the unauthorized disclosure of facts about individuals’ chronic physical or mental health conditions, medical treatments and treatment choices, life expectancy, disability status, parental status, substance addiction, sexual and reproductive health, and sexual orientation, as well as other information,” the FTC said.

“Disclosure of this information without authorization is likely to cause GoodRx users stigma, embarrassment, or emotional distress, and may also affect their ability to obtain or retain employment, housing, health insurance, disability insurance, or other services.”

In a press release, GoodRx said the FTC was focusing on an “old issue” that it addressed and corrected three years ago. “Millions of Americans use GoodRx to save on their healthcare, and we take strong measures to ensure they can trust us with their information,” the company said.

Data mining isn’t limited to healthcare providers, advertisers, internet companies or law enforcement. Medical researchers also use it, to track and evaluate patient conditions and the effectiveness of treatments. Some would also like to use data to predict patient outcomes.

In a new study, researchers at the University of Alberta said they had devised a form of artificial intelligence -- based on patient health data -- that can predict with 90% accuracy whether a patient is at risk of an adverse outcome from opioid prescriptions. Researchers say their model could be used someday to warn doctors about high-risk patients, so they can prescribe another drug or give smaller doses.

A Get Well Message to the Pain Community

By Mia Maysack, PNN Columnist

One of the things that has distanced me from hands-on participation in the pain community is the persistent negativity. I’m not the only advocate that has picked up on this, nor alone in feeling the need to step away as a result.

Don’t get me wrong. As a former healthcare provider, I understand and am sensitive to the fact that people aren’t chipper on their hardest days or when they’re experiencing a tremendous amount of discomfort. And being a patient myself, there have been and will continue to be moments where I drop the ball in regards to being “positive.” My vision is literally and figuratively blurred on those days -- to the point where it’s not easy to see any bright side or silver lining.

But each attempt I make to provide meaningful commentary on what has assisted, changed or even saved my life is met with objections. One of the most infamous lines goes something like: “Some of us have incurable conditions!”

It’s as if my post bacterial-meningitis intractable mega-migraines, irreparable cellular nerve damage, evolving arthritis, immobilizing fibromyalgia, and the fact I’ve lived this way for two decades and counting doesn’t have any merit or meaning.

It’s quite frustrating to devote so much of your experience, skills and compassion to people who condemn you for attempting to transform your suffering – while they contribute to that very suffering. The whole “misery loves company” thing is a bit played out with me. I believe a much more productive use of energy is to get to the root of our misery, as opposed to clinging to it and passing it on.

Any time I offer up alternative pain modalities that have proven helpful for me, along with millions of others for thousands of years, while always treading lightly on the eggshells of disclaimers about everything not being for everyone, nothing can completely fix our problems, it’s a process of trial and error, etc. –  I’m torn down by the very same people.

How is this supposed to elevate anyone or make anything better?

I’ve been mocked, ridiculed, silenced and even threatened when mentioning things such as mindfulness, meditation and neuroplasticity. But companies have invested in and now offer all of those therapies.

This is in part what led me to step away from patient support groups, because most don’t desire actual support, but seek more space to complain. I wholeheartedly understand and believe it is of utmost importance for our grievances to somehow exist outside of ourselves, but I’ve found that support can only get us so far.  It then becomes more about self-help, which is something that most people have a difficult time realizing or pursuing, especially when illness or pain are major obstacles blocking the way.

Sometimes, those of us who have risen from the depths of our own versions of hell are judged and labeled by remarks that we couldn’t possibly be sick. That somehow, we’re more privileged than the next patient or had opportunities that others don’t have and cannot get.

In actuality,  we are revolutionaries who saw that treatments were not working and made a conscious decision to devote our lives to assisting others through their hardships. Not because anything is gained or money made, but because it is the right thing to do. We were once consumed by the fire as well, but now venture out with buckets of water for the rest of you.

It is mostly thankless, often torn down, and difficult to take on the weight of what can feel like hatred, all the while attempting to balance and manage the ailments that already threaten us. Irony is found in the fact that so much of the condemning originates from people who do the absolute least for this community. 

The time has come to understand this conduct as a sickness in itself, and that it causes a negative ripple effect that limits us all from the ability to move forward.

I’m thrilled to see articles about things such as how healing is just as important as pain relief, or how childhood experiences that seem to have little to do with our current conditions can still directly impact how our bodies and minds feel.  And it’s always encouraging to come across a list of low-to-no side effect modalities to at least consider, if not try.

This doesn’t mean belittling anybody's experience. Release the illusion of stories you’ve always told to yourself or were told to you. Make room for a new chapter and fight for your lives, not against those who want you to thrive. And get well soon.

New Test Predicts Effectiveness of CGRP Drugs for Migraine

By Pat Anson, PNN Editor

CGRP inhibitors have been one of the biggest innovations in migraine treatment in decades. CGRP stands for calcitonin gene-related peptides, a protein that binds to nerve receptors in the brain and triggers migraine pain. Since 2018, the FDA has approved over half a dozen CGRP inhibitors for migraine prevention and treatment.

The problem with anti-CGRP therapies – besides their high cost – is that they only work for about half the people who take them.

A new test may take some of the guesswork out of CGRP therapy, by predicting with about 80% accuracy which patients will respond to CGRP inhibitors before treatment begins.  In a small study published in the journal Cephalalgia, Harvard Medical School researchers found that most migraine patients with non-ictal cephalic allodynia -- pain sensitivity experienced in-between migraine attacks – did not respond to CGRP treatment. Conversely, most patients without non-ictal cephalic allodynia did respond to CGRP therapy.  

Determining which patients have or don’t have cephalic allodynia is relatively easy, through a novel Quantitative Sensory Testing (QST) algorithm that measures how sensitive patients are to heat, cold and being poked in the skin with a sharp object. The test identified CGRP responders with nearly 80% accuracy and non-responders with nearly 85% accuracy.

“Detection of non-ictal cutaneous allodynia with a simplified paradigm of QST may provide a quick, affordable, non-invasive, and patient-friendly way to prospectively distinguish between responders and non-responders to the prophylactic treatment of migraine with drugs that reduce CGRP signaling,” wrote lead author Rami Burstein, MD, Professor of Anesthesia, Harvard Medical School.

Burstein helped develop the QST test in collaboration with CGRP Diagnostics. The test can be done in about five minutes in a doctor’s office.

“This is all about improving outcomes for people suffering from migraines and so we strongly recommend that all potential anti-CGRP recipients have the test done prior to prescription,” said Mark Hasleton, PhD, CEO of CGRP Diagnostics. 

“This will help provide migraine sufferers with either the best chance for treatment success for likely responders, or to enable rapid transition for likely non-responders to other treatment strategies, thus avoiding the misery of treatment failure. CGRP Diagnostics is currently in discussions with multiple key pharma and payor players in this area, with the expectation that such a test will become a prerequisite prior to anti-CGRP prescription.”

A surprise finding from the study is that cutaneous allodynia may be related to genetic factors that cause pain sensitivity, rather than the frequency or severity of migraines.

“This study unveils the mechanism of physiological response to anti-CGRP therapy and could fundamentally change the anti-CGRP therapy field,” said Iris Grossman, PhD, Founding Scientific Advisor at CGRP Diagnostics. “We now have an objective tool to tailor early and effective therapy to migraine sufferers. This novel test holds the potential for earlier access to anti-CGRP therapy, reduced need for prior treatment failures with generics, and enhanced formulary access. It also enables non-responders to rapidly transition to other treatment strategies, preventing a great deal of suffering and frustration for all.”

A 2020 survey of migraine patients by Health Union found that 52% of those who tried a CGRP therapy switched brands because the treatment didn’t work or because they didn’t like the side effects, such as constipation and weight gain.

CGRP medications are not cheap. Eight doses of Nurtec, the migraine treatment endorsed by Khloe Kardashian, can cost over $1,000 without insurance.

Migraine affects more than 37 million people in the United States, according to the American Migraine Foundation. In addition to headache pain, migraine can cause nausea, blurriness or visual disturbances, and sensitivity to light and sound. Women are three times more likely to suffer from migraines than men.

New VA Guideline: Opioids Should Not Be Used for Chronic Pain

By Pat Anson, PNN Editor

The U.S. Department of Defense (DoD) and Department of Veterans Affairs (VA) have doubled down on a guideline first released in 2017 that strongly recommends against the use of opioids for chronic pain.

In an updated clinical practice guideline, the agencies continue to recommend that opioids not be used to manage chronic non-cancer pain, especially in younger patients, and that long-acting opioids not be used to treat patients with short-term, acute pain.

The VA/DoD guideline will potentially affect millions of service members, veterans and their families. Nearly 1.5 million Americans serve in the armed forces and over 800,000 in the National Guard and Reserves. The Veterans Administration provides health services to another 6 million veterans and their families.

The updated guideline was quietly released in May 2022, but is only drawing attention now in a mostly favorable review published in the Annals of Internal Medicine.

“Compared with the 2017 recommendation against initiation of long-term opioid therapy, the updated recommendation against opioid therapy in general for chronic pain is broader and reflects the evidence that opioid therapy for any duration may be harmful,” wrote lead author James Sall, PhD, Director of VA’s Office of Evidence-Based Practice.

“Ultimately, despite finding some evidence for a small improvement in musculoskeletal and noncancer neuropathic pain, the guideline development group maintained that the potential for catastrophic harms of opioids and serious adverse events, especially with long-term use, outweighed any potential benefits of temporarily improved pain severity and functional status in patients with chronic pain.”

‘Potentially Transformative’ for U.S. Healthcare

The updated opioid guideline has 20 recommendations, nine of which are based on weak or inconclusive evidence. Unlike the recently revised CDC opioid guideline, there were no public hearings or opportunities for the public to comment or provide input. There is also no discussion of dose thresholds or morphine milligram equivalents (MME), suggesting the authors believe that any dose of opioids is potentially risky.

Three new recommendations in the new VA/DoD guideline involve opioid tapering, mental health evaluations, and the use of buprenorphine to treat pain.

The guideline urges doctors to consider using buprenorphine instead of full agonist opioids for patients needing opioids daily for chronic pain. Although the quality of the evidence for this recommendation was deemed “insufficient,” the VA/DoD believe buprenorphine as a partial agonist has less risk for overdose and misuse, and is less likely to cause euphoria.

Buprenorphine is a Schedule III opioid that is FDA approved for pain when used alone. Buprenorphine is also used to treat opioid use disorder when combined with naloxone in drugs like Suboxone. The DEA recently eliminated the “X-Waiver” program for buprenorphine, which is likely to significantly increase the number of doctors that prescribe it and the number of patients that receive it.

An editorial published in the Annals of Internal Medicine called the recommendation that buprenorphine be used for pain “potentially transformative” and "likely to expand into the greater U.S. healthcare system."

"The updated VA/DoD guideline is both conservative and radical," wrote co-authors Chinazo Cunningham, MD, and Joanna Starrels, MD, both from Albert Einstein College of Medicine. "Although the VA/DoD guideline recommends that buprenorphine be prescribed for chronic pain if daily opioids are prescribed, the recommendation itself is likely to change decision-making about whether opioids should be prescribed."

Although several recent studies have found that opioid tapering significantly raises the risk of an overdose, withdrawal or mental health crisis, the VA/DoD guideline found there is “insufficient evidence to recommend for or against any specific tapering strategies.” It only recommends that doctors and patients “collaborate” on reducing opioid doses and that tapering not be forced.

“The potential benefits of opioid tapering outweighed the potential harms of opioid withdrawal,” the guideline claims.

Before opioids are prescribed for either acute or chronic pain, the guideline recommends that the mental health of patients be evaluated for depression, anxiety, psychotic disorders and suicide. Although some patients may resent being screened for mental health problems, the guideline says “it is better for providers to know about underlying behavioral health comorbidities than to initiate long-term opioids without this clinical knowledge.”

The revised guideline reaffirms previous recommendations that benzodiazepines not be co-prescribed with opioids and that patients on long-term opioid therapy be regularly screened with urine drug tests “to decrease the risk of self-directed violence.”

Opioid prescribing to veterans, family members and those on active duty has declined significantly in recent years, as it has for the rest of the population. The revised VA/DoD guideline notes – without a hint of irony – that reduced prescribing has led to an increased use of illicit opioids by veterans and higher overdose rates.
