Opioid deaths in North America predicted to soar

Article Type

Mon, 02/14/2022 - 10:14

Without bold and urgent action, including public health policy reform and stricter corporate regulations, an additional 1.2 million people in North America will die of an opioid overdose by 2029, according to an analysis by the Stanford-Lancet Commission.

“Over the past quarter-century, the opioid epidemic has taken nearly 600,000 lives and triggered a cascade of public health catastrophes such as disability, family breakdown, unemployment, and child neglect in North America,” commission chair Keith Humphreys, PhD, said in a news release.

“If no action is taken, by the end of this decade, we are predicting the number of deaths to be twice as high as it has been over the last 20 years,” said Dr. Humphreys, professor of psychiatry and behavioral sciences at Stanford (Calif.) University.

The report was published online Feb. 2, 2022, in The Lancet.
 

Blame it on COVID-19?

The COVID-19 pandemic has both overshadowed and exacerbated the opioid crisis in North America, the commission pointed out in their report.

Their analysis suggests that 2020 was the worst year on record for overdose deaths in the United States and Canada in terms of both the total number of deaths and percentage annual increase.

In the United States, opioid overdose deaths increased by 37%, from 51,133 in 2019 to 70,168 in 2020, bringing the total number of deaths since 1999 to 583,000.

In Canada, opioid overdose deaths jumped by 72%, from 3,668 in 2019 to 6,306 in 2020, with a further 3,515 deaths reported in the first 6 months of 2021.

Although the 2020 spikes might be partly caused by the effects of the COVID-19 pandemic, a rising trajectory of deaths was evident in both the United States and Canada before the pandemic hit, the Stanford-Lancet Commission said.
 

Profit motives, lack of regulation

The commission blames the opioid epidemic on a lack of adequate regulation and oversight coupled with profit motives of the pharmaceutical and health care industry.

“To ensure safeguards are in place to curb the opioid addiction epidemic and prevent future ones involving other addictive drugs, we must end the pharmaceutical and health care industry’s undue influence on the government and its unregulated push for opioid use,” commission member Howard Koh, MD, MPH, said in the news release.

“This includes insulating the medical community from pharmaceutical company influence and closing the constantly revolving door between regulators and industry,” said Dr. Koh, with the Harvard School of Public Health, Boston.

In addition to regulation and policy reform, the commission said prevention efforts that focus on treating addiction as a chronic condition are key.

The United States in particular lacks accessible, high-quality, nonstigmatizing, and integrated health and social care services for people experiencing opioid use disorder, the Commission notes.

Addiction-related services must become a permanent feature of health and social care systems in the United States and Canada, in line with established chronic disease management models that are financed and organized as a core public health commitment, the commission said.

“Addiction is an enduring part of population health and should not be treated as a moral failing that needs punishment but as a chronic health condition that requires ongoing treatment and long-term support,” commission member Yasmin Hurd, PhD, director of the Addiction Institute at Icahn School of Medicine at Mount Sinai, New York, said in the release.

Investing in young people to reduce the risk of addiction will also be important going forward.

“Preventing drug addiction should be part of a comprehensive public health strategy that starts in childhood and lays the foundation for long-term declines in addiction,” said commission member Chelsea Shover, PhD, with the University of California, Los Angeles.
 

 

 

‘Audacious but achievable goal’

The commission calls for a nuanced approach to pain management that prioritizes innovation both in society’s response to drug addiction through policy reform and by supporting the development of new, nonaddictive pain management options.

“Opioids should not be viewed as good or bad, but instead as a class of medications essential to the management of pain. However, opioids also come with serious risks, some of which can be difficult to recognize,” commission member David Juurlink, MD, PhD, said in the release.

“Clinicians should begin learning about responsible pain management prescribing in medical school and continue to learn about it as part of their commitment to continued medical education throughout their careers,” said Dr. Juurlink, with Sunnybrook Health Sciences Centre in Toronto.

Humphreys said ending the opioid epidemic in North America and preventing its global spread is “an audacious but achievable goal” that will require a “dramatic shift in policy and culture where innovation, collaboration, and regulation are encouraged.

“We can save and improve lives by summoning the resources and political will necessary to eliminate the sources of addiction and boldly implement policies that will maximize efforts to treat it,” Dr. Humphreys added.

The study was funded by Stanford University.

E-cigarettes don’t help smokers quit, suggests new research

Article Type
Changed
Mon, 02/28/2022 - 11:41

Use of e-cigarettes was not more effective than other methods at helping cigarette smokers quit, authors of new research found.

From 2013 to 2017, e-cigarette sales in the United States nearly doubled, driven by a rapid uptake of use by adolescents, wrote Riufeng Chen, MD, of the University of California, San Diego, and colleagues, in their paper published in Tobacco Control. However, the subsequent effect of increased e-cigarette use on smoking cessation have not been examined, they said.

In their study, Dr. Chen and colleagues analyzed data from 3,578 previous-year smokers with a recent quit attempt and 1,323 recent former smokers who were part of the PATH cohort in 2017. The participants reported using e-cigarettes or other products to quit cigarette smoking. The primary outcomes were at least 12 months of cigarette abstinence, and tobacco abstinence in 2019. In 2017, 32.8% of established smokers reported trying to quit. Of these, 12.6% used e-cigarettes to help them quit. Cigarette abstinence for at least 12 months for these individuals was 9.9%, which was lower than for those who used either nicotine replacement therapy or a pharmaceutical aid only (15.2%), and about half of the 18.6% abstinence in those who used no products to help them quit.

“In our study, e-cigarettes resulted in seven fewer successful quitters than those who used pharmaceutical aids,” emphasized corresponding author, John P. Pierce, PhD, of the University of California, San Diego.

Among smokers attempting to quit, the adjusted risk difference for cigarette abstinence for a least 12 months with e-cigarettes vs. pharmaceutical aids was –7.3%, and –7.7% for e-cigarettes vs. other smoking cessation methods.

*“Among recent former smokers who had switched to daily use of e-cigarettes in 2017, 43.2% had successfully quit cigarette smoking by 2019, which was similar to those who used e-cigarettes on a nondaily basis (34.6%) or to those who switched to another tobacco product, whether daily (43.6%) or nondaily (44.7%),” the researchers wrote.

The rapid growth in e-cigarette use between 2014 and 2017 has been attributed in part to aggressive marketing of high-nicotine e-cigarettes, they said. “The high-nicotine JUUL e-cigarette has been noted as the closest match to cigarettes in both nicotine delivery and user satisfaction, which should make it one of the best candidates as a product to which smokers could switch in order to maintain their nicotine habit,” they said in their discussion of the findings.

More research needed

The researchers acknowledged the need to review more recent data.

“When we looked ahead to 2019, recent former smokers had started using high-nicotine e-cigarettes. The effectiveness of high-nicotine e-cigarettes at preventing relapse will require another follow-up PATH survey,” they said.

Among recent former smokers, 2.2% reported switching to a high-nicotine e-cigarette. Although individuals who switched to e-cigarettes showed a higher rate of relapse to cigarettes than those who did not switch to other tobacco or e-cigarette products, this difference was not significant.

The study findings were limited by several factors including the observational design and inability to control for all potential confounding factors, the researchers noted. However, the results were strengthened by the use of a large and representative study population, and the inclusion of biological samples to validate self-reported smoking, they said.
 

 

 

Several findings surprised study author

Dr. Pierce said he was surprised by several aspects of the study findings.

“First of all, contrary to what we expected, there was a 25% decline in using e-cigarettes to quit, compared to the previous year (not the 40% increase that was expected from the increase in e-cigarette sales) and almost no smokers were using high-nicotine JUUL products to help them quit,” he said. “In this study, e-cigarettes were much less helpful (7 less successful quitters per 100) than pharmaceutical cessation aids in helping people quit,” he added.

“The fact that the proportion of smokers using e-cigarettes for cessation dropped from 17% to 12% was unexpected, and it suggests that the belief that they are a cessation aid is declining,” he said.

The implication for clinical practice is that e-cigarettes are not a useful tool for smoking cessation, Dr. Pierce said. “We are not finding any evidence in this very large nationally representative study that smokers who switch to getting their nicotine from e-cigarettes are less likely to relapse back to cigarette smoking,” he said.

“We don’t know about the high-nicotine versions,” he added. 
 

New review advises against e-cigarettes for cessation

A recent review article published in JAMA supported the use of pharmacotherapy and behavioral support for smokers wanting to quit. In the review, Nancy A. Rigotti, MD, of Massachusetts General Hospital, Boston, and colleagues summarized the evidence for managing tobacco smoking in clinical practice.

“The health risk from cigarette smoking is primarily due to chemicals produced by the burning of tobacco and not to nicotine,” they noted. However, the physical dependence on nicotine makes quitting a challenge, but it is one worth pursuing, the authors said.

The authors of this review identified 30 reviews, 12 randomized clinical trials, and 7 recent guidelines and evidence reviews. Their key message: Pharmacotherapy and behavioral support are effective when used alone, but even more effective when combined. Pharmacotherapy helps reduce the symptoms of nicotine withdrawal, while behavioral intervention tackles the challenge of changing learned behaviors associated with smoking, the researchers said.

Although combining medications, such as varenicline and nicotine replacement therapy or bupropion might improve successful quit rates, these combinations have not been well studied, they noted.

With regard to e-cigarettes, the researchers cited a 2021 Cochrane review of 16,759 individuals who used e-cigarettes for smoking cessation, which found no evidence of harm, but insufficient evidence to asses the balance of risks vs. benefits.

In addition to the lack of randomized trials, “the FDA regulates e-cigarettes as tobacco products, not as medical products and has not evaluated any e-cigarette for medical use as a cessation aid,” the authors of the new review noted.

The review was limited by several factors, including the lack of quality assessment for the selected studies and the exclusion of pharmacotherapy not licensed in the United States.

Commenting on the JAMA paper, Dr. Pierce said, “This review looks like a number of Cochrane Reports that have been published recently. Of course, it only considers randomized trials and not population evidence.”

“If public health had limited itself to this form of evidence, then we still would not know that smoking caused cancer,” he noted. “Randomized trials are very important for testing new drugs; they use selected populations and provide considerable support that is not available in the real world. Sometimes they do not generalize to the population.”
 

 

 

Findings may guide patient conversations

The Tobacco Control study was important, because few studies on e-cigarettes have been conducted, said Linda Girgis, MD, a family physician in private practice in South River, N.J., in an interview.

“As clinicians, we do not have a lot of data available in order to make clinical decisions that are evidence based. Also, getting patients to quit smoking is often very difficult, and having more tools available is a great benefit; however, we need to have the evidence that these tools are effective,” she said.

Dr. Girgis also said she was not surprised by the findings.

“Patients still have the same concerns from e-cigarettes regarding nicotine exposure, but just to a lesser degree; and we still don’t know the long-term effects of e-cigarette use, she said. Based on these studies, recommending e-cigarettes for smokers looking to quit may not be the best method, she noted.

“While it may seem reasonable that exposing lungs to lower doses of nicotine will reduce harm, we need to see actual evidence of this. Also, we also need to study the additives that are frequently used in e-cigs, such as artificial flavorings, to see what harms they may pose, she emphasized.

With regard to the JAMA review, Dr. Girgis said she agreed with the recommendations for pharmacotherapy and behavior therapy as first-line treatments for smoking cessation. “There is evidence regarding the efficacy and safety of these methods, and they have been used for decades,” she said.

Dr. Girgis added that there is a role for e-cigarettes in smoking cessation strategies as a method of harm reduction, but pointed out the problem of many people thinking these products are safe and not understanding the hazards they pose.

“They think they can replace smoking with e-cigarettes and be safe from the health risks associated with smoking. I think if the plan were to switch to e-cigarettes for a short period and then quit, there would be a role,” Dr. Girgis said. “However, replacing one risk for another may reduce harm, but doesn’t eliminate it.”

“To continue to use e-cigarettes indefinitely should not be the goal,” she added.

The Tobacco Control study was funded by the National Institutes of Health and the Tobacco-Related Disease Research Program of the University of California. The researchers had no financial conflicts to disclose.

The JAMA study was funded in part by a grant from the National Institute for Health Research, via Cochrane Infrastructure funds to the Cochrane Tobacco Addiction Group. Lead author Dr. Rigotti disclosed funding from the National Heart, Lung, and Blood Institute and Achieve Life Sciences and personal fees from UpToDate and Achieve Life Sciences. Dr. Girgis had no financial conflicts to disclose.

Also, getting patients to quit smoking is often very difficult, and having more tools available is a great benefit; however, we need to have the evidence that these tools are effective,” she said.

Dr. Girgis also said she was not surprised by the findings.

“Patients still have the same concerns from e-cigarettes regarding nicotine exposure, but just to a lesser degree; and we still don’t know the long-term effects of e-cigarette use, she said. Based on these studies, recommending e-cigarettes for smokers looking to quit may not be the best method, she noted.

“While it may seem reasonable that exposing lungs to lower doses of nicotine will reduce harm, we need to see actual evidence of this. Also, we also need to study the additives that are frequently used in e-cigs, such as artificial flavorings, to see what harms they may pose, she emphasized.

With regard to the JAMA review, Dr. Girgis said she agreed with the recommendations for pharmacotherapy and behavior therapy as first-line treatments for smoking cessation. “There is evidence regarding the efficacy and safety of these methods, and they have been used for decades,” she said.

Dr. Girgis added that there is a role for e-cigarettes in smoking cessation strategies as a method of harm reduction, but pointed out the problem of many people thinking these products are safe and not understanding the hazards they pose.

“They think they can replace smoking with e-cigarettes and be safe from the health risks associated with smoking. I think if the plan were to switch to e-cigarettes for a short period and then quit, there would be a role,” Dr. Girgis said. “However, replacing one risk for another may reduce harm, but doesn’t eliminate it.”

“To continue to use e-cigarettes indefinitely should not be the goal,” she added.

The Tobacco Control study was funded by the National Institutes of Health and the Tobacco-Related Disease Research Program of the University of California. The researchers had no financial conflicts to disclose.

The JAMA study was funded in part by a grant from the National Institute for Health Research, via Cochrane Infrastructure funds to the Cochrane Tobacco Addiction Group.

Use of e-cigarettes was not more effective than other methods at helping cigarette smokers quit, authors of new research found.

From 2013 to 2017, e-cigarette sales in the United States nearly doubled, driven by a rapid uptake of use by adolescents, wrote Riufeng Chen, MD, of the University of California, San Diego, and colleagues, in their paper published in Tobacco Control. However, the subsequent effect of increased e-cigarette use on smoking cessation have not been examined, they said.

In their study, Dr. Chen and colleagues analyzed data from 3,578 previous-year smokers with a recent quit attempt and 1,323 recent former smokers who were part of the PATH cohort in 2017. The participants reported using e-cigarettes or other products to quit cigarette smoking. The primary outcomes were at least 12 months of cigarette abstinence, and tobacco abstinence in 2019. In 2017, 32.8% of established smokers reported trying to quit. Of these, 12.6% used e-cigarettes to help them quit. Cigarette abstinence for at least 12 months for these individuals was 9.9%, which was lower than for those who used either nicotine replacement therapy or a pharmaceutical aid only (15.2%), and about half of the 18.6% abstinence in those who used no products to help them quit.

“In our study, e-cigarettes resulted in seven fewer successful quitters than those who used pharmaceutical aids,” emphasized corresponding author, John P. Pierce, PhD, of the University of California, San Diego.

Among smokers attempting to quit, the adjusted risk difference for cigarette abstinence for a least 12 months with e-cigarettes vs. pharmaceutical aids was –7.3%, and –7.7% for e-cigarettes vs. other smoking cessation methods.

*“Among recent former smokers who had switched to daily use of e-cigarettes in 2017, 43.2% had successfully quit cigarette smoking by 2019, which was similar to those who used e-cigarettes on a nondaily basis (34.6%) or to those who switched to another tobacco product, whether daily (43.6%) or nondaily (44.7%),” the researchers wrote.

The rapid growth in e-cigarette use between 2014 and 2017 has been attributed in part to aggressive marketing of high-nicotine e-cigarettes, they said. “The high-nicotine JUUL e-cigarette has been noted as the closest match to cigarettes in both nicotine delivery and user satisfaction, which should make it one of the best candidates as a product to which smokers could switch in order to maintain their nicotine habit,” they said in their discussion of the findings.

More research needed

The researchers acknowledged the need to review more recent data.

“When we looked ahead to 2019, recent former smokers had started using high-nicotine e-cigarettes. The effectiveness of high-nicotine e-cigarettes at preventing relapse will require another follow-up PATH survey,” they said.

Among recent former smokers, 2.2% reported switching to a high-nicotine e-cigarette. Although individuals who switched to e-cigarettes showed a higher rate of relapse to cigarettes than those who did not switch to other tobacco or e-cigarette products, this difference was not significant.

The study findings were limited by several factors including the observational design and inability to control for all potential confounding factors, the researchers noted. However, the results were strengthened by the use of a large and representative study population, and the inclusion of biological samples to validate self-reported smoking, they said.
 

 

 

Several findings surprised study author

Dr. Pierce said he was surprised by several aspects of the study findings.

“First of all, contrary to what we expected, there was a 25% decline in using e-cigarettes to quit, compared to the previous year (not the 40% increase that was expected from the increase in e-cigarette sales) and almost no smokers were using high-nicotine JUUL products to help them quit,” he said. “In this study, e-cigarettes were much less helpful (7 less successful quitters per 100) than pharmaceutical cessation aids in helping people quit,” he added.

“The fact that the proportion of smokers using e-cigarettes for cessation dropped from 17% to 12% was unexpected, and it suggests that the belief that they are a cessation aid is declining,” he said.

The implication for clinical practice is that e-cigarettes are not a useful tool for smoking cessation, Dr. Pierce said. “We are not finding any evidence in this very large nationally representative study that smokers who switch to getting their nicotine from e-cigarettes are less likely to relapse back to cigarette smoking,” he said.

“We don’t know about the high-nicotine versions,” he added. 
 

New review advises against e-cigarettes for cessation

A recent review article published in JAMA supported the use of pharmacotherapy and behavioral support for smokers wanting to quit. In the review, Nancy A. Rigotti, MD, of Massachusetts General Hospital, Boston, and colleagues summarized the evidence for managing tobacco smoking in clinical practice.

“The health risk from cigarette smoking is primarily due to chemicals produced by the burning of tobacco and not to nicotine,” they noted. However, the physical dependence on nicotine makes quitting a challenge, but it is one worth pursuing, the authors said.

The authors of this review identified 30 reviews, 12 randomized clinical trials, and 7 recent guidelines and evidence reviews. Their key message: Pharmacotherapy and behavioral support are effective when used alone, but even more effective when combined. Pharmacotherapy helps reduce the symptoms of nicotine withdrawal, while behavioral intervention tackles the challenge of changing learned behaviors associated with smoking, the researchers said.

Although combining medications, such as varenicline and nicotine replacement therapy or bupropion might improve successful quit rates, these combinations have not been well studied, they noted.

With regard to e-cigarettes, the researchers cited a 2021 Cochrane review of 16,759 individuals who used e-cigarettes for smoking cessation, which found no evidence of harm, but insufficient evidence to asses the balance of risks vs. benefits.

In addition to the lack of randomized trials, “the FDA regulates e-cigarettes as tobacco products, not as medical products and has not evaluated any e-cigarette for medical use as a cessation aid,” the authors of the new review noted.

The review was limited by several factors, including the lack of quality assessment for the selected studies and the exclusion of pharmacotherapy not licensed in the United States.

Commenting on the JAMA paper, Dr. Pierce said, “This review looks like a number of Cochrane Reports that have been published recently. Of course, it only considers randomized trials and not population evidence.”

“If public health had limited itself to this form of evidence, then we still would not know that smoking caused cancer,” he noted. “Randomized trials are very important for testing new drugs; they use selected populations and provide considerable support that is not available in the real world. Sometimes they do not generalize to the population.”
 

 

 

Findings may guide patient conversations

The Tobacco Control study was important, because few studies on e-cigarettes have been conducted, said Linda Girgis, MD, a family physician in private practice in South River, N.J., in an interview.

Scientists see hope in new therapy for COVID-19 brain fog patients

Article Type
Changed
Tue, 05/24/2022 - 16:20

People with long-COVID “brain fog” may be able to recover mental abilities that were dulled or stolen from them by the virus through an approach that has improved the effects of stroke, traumatic brain injury, and other post-viral disorders, doctors and scientists say.

For a lucky portion of the population, COVID-19 lasts a handful of days with minor symptoms. But for an estimated 37% who contract the virus, symptoms can linger for weeks, months, or even years. One of the most common symptoms of long COVID is brain fog: a life-altering condition characterized by slow thinking, confusion, difficulty remembering things, and poor concentration.

A type of rehabilitation program that allows the brain to rewire itself has been successful in improving the lives of people with brain fog. The approaches are based on the concept of neuroplasticity: The ability of neural networks in the brain to change, adapt, and strengthen, much like a muscle in the body that has been trained and exercised.

“The brain’s ability to bounce back from injury is what neuroplasticity is, and I’ve worked with people in our rehab clinic who have had brain tumors or suffer the effects of surgery or radiation on the brain, and people who have had West Nile virus, HIV, and meningitis,” said Tom Bergquist, PhD, clinical neuropsychologist at Mayo Clinic in Rochester, Minn. “There’s not a week that goes by that I don’t see someone recovering from COVID-19.”

One of the approaches used in the clinic is errorless learning, or having a patient with memory problems repeat information a certain number of times without error. The repetition helps rebuild those memory skills that were weakened during infection, Dr. Bergquist says.

People who have experienced brain fog after other viral infections have seen improvements with these approaches. Ben Ahrens, co-founder and CEO of re-origin – a company that offers neuroplasticity therapy – says he had long-term cognitive issues after a Lyme disease infection. Posttreatment Lyme disease syndrome, or chronic Lyme disease, occurs in about 1 in 10 people who are infected.

Mr. Ahrens says he was struck with Lyme 10 years ago and had brain fog, joint pain, and brain lesions detectable on scans for several years after infection.

According to Mr. Ahrens, neuroplasticity-based therapies help combat what researchers have found may be a lingering memory of past infections that lead to a heightened immune response, causing lingering symptoms.

“Essentially, what we believe is happening here, is the brain has learned that these symptoms are life-threatening – because, in fact, they can be,” Mr. Ahrens said. “The brain’s one job is to protect the body, and once it’s learned to associate these symptoms with that potentially very dangerous pathogen, even after it’s gone, things like a normal headache can trigger an immune cascade.”

Studies are underway at the University of Alabama at Birmingham to examine whether constraint-induced therapy – an approach rooted in neuroplasticity and historically used for loss of limb and speech function – is also effective for cognitive impairments like brain fog.

One technique they use is called shaping, which requires a person to repeatedly carry out their personal best function of impaired use – for example, remembering household tasks they have previously forgotten. That is done multiple times over several weeks in the clinic, and patients are given ways to transfer those skills to real-life use.

So far, the results are promising, said Edward Taub, PhD, researcher and professor of psychology at the University of Alabama at Birmingham.

When used in the past for physical impairments, researchers have noted not just clinical improvements, but structural changes. It led to an increase in the brain’s gray matter – which allows individuals to control movement, memory, and emotions – and improved white matter, which helps communication between gray matter areas.

Though results of the cognitive studies have not been published, Dr. Taub said patients with brain fog have shown improvement after just 35 hours of therapy and are nearly 100% improved after 6 months.

“The idea behind this is that the brain is responsive to use,” Dr. Taub said. “The amount of brain territory that’s dedicated to supporting or mediating a given behavioral function depends on the demands placed on the brain.”

Seniors face higher risk of other medical conditions after COVID-19

Article Type
Changed
Tue, 05/24/2022 - 16:21

Nearly one-third of adults over age 65 developed one or more new medical conditions in the weeks following a COVID-19 infection, according to new research.

The findings of the observational study, which were published in the BMJ, show the risk of a new condition being triggered by COVID is more than twice as high in seniors, compared with younger patients. Plus, the researchers observed an even higher risk among those who were hospitalized, with nearly half (46%) of patients having developed new conditions after the acute COVID-19 infection period.

Respiratory failure with shortness of breath was the most common postacute sequela, but a wide range of heart, kidney, lung, liver, cognitive, mental health, and other conditions were diagnosed at least 3 weeks after initial infection and persisted beyond 30 days.

This is one of the first studies to specifically describe the incidence and severity of new conditions triggered by COVID-19 infection in a general sample of older adults, said study author Ken Cohen MD, FACP, executive director of translational research at Optum Labs and national senior medical director at Optum Care.

“Much of what has been published on the postacute sequelae of COVID-19 has been predominantly from a younger population, and many of the patients had been hospitalized,” Dr. Cohen noted. “This was the first study to focus on a large population of seniors, most of whom did not require hospitalization.”

Dr. Cohen and colleagues reviewed the health insurance records of more than 133,000 Medicare beneficiaries aged 65 or older who were diagnosed with COVID-19 before April 2020. They also matched individuals by age, race, sex, hospitalization status, and other factors to comparison groups without COVID-19 (one from 2020 and one from 2019), and to a group diagnosed with other lower respiratory tract viral infections before the pandemic.
 

Risk of developing new conditions was higher in hospitalized

After acute COVID-19 infection, 32% of seniors sought medical care for at least one new medical condition in 2020, compared with 21% of uninfected people in the same year.

The most commonly observed conditions included:

  • Respiratory failure (7.55% higher risk).
  • Fatigue (5.66% higher risk).
  • High blood pressure (4.43% higher risk).
  • Memory problems (2.63% higher risk).
  • Kidney injury (2.59% higher risk).
  • Mental health diagnoses (2.5% higher risk).
  • Blood-clotting disorders (1.47 % higher risk).
  • Heart rhythm disorders (2.9% higher risk).

The risk of developing new conditions was even higher among those 23,486 who were hospitalized in 2020. Those individuals showed a 23.6% higher risk for developing at least one new condition, compared with uninfected seniors in the same year. Also, patients older than 75 had a higher risk for neurological disorders, including dementia, encephalopathy, and memory problems. The researchers also found that respiratory failure and kidney injury were significantly more likely to affect men and Black patients.

When those who had COVID were compared with the group with other lower respiratory viral infections before the pandemic, only the risks of respiratory failure (2.39% higher), dementia (0.71% higher), and fatigue (0.18% higher) were higher.

Primary care providers can learn from these data to better evaluate and manage their geriatric patients with COVID-19 infection, said Amit Shah, MD, a geriatrician with the Mayo Clinic in Phoenix, in an interview.

“We must assess older patients who have had COVID-19 for more than just improvement from the respiratory symptoms of COVID-19 in post-COVID follow-up visits,” he said. “Older individuals with frailty have vulnerability to subsequent complications from severe illnesses and it is common to see post-illness diagnoses, such as new diagnosis of delirium; dementia; or renal, respiratory, or cardiac issues that is precipitated by the original illness. This study confirms that this is likely the case with COVID-19 as well.

“Primary care physicians should be vigilant for these complications, including attention to the rehabilitation needs of older patients with longer-term postviral fatigue from COVID-19,” Dr. Shah added.
 

 

 

Data predates ‘Omicron wave’

It remains uncertain whether sequelae will differ with the Omicron variant, but the findings remain applicable, Dr. Cohen said.

“We know that illness from the Omicron variant is on average less severe in those that have been vaccinated. However, throughout the Omicron wave, individuals who have not been vaccinated continue to have significant rates of serious illness and hospitalization,” he said.

“Our findings showed that serious illness with hospitalization was associated with a higher rate of sequelae. It can therefore be inferred that the rates of sequelae seen in our study would continue to occur in unvaccinated individuals who contract Omicron, but might occur less frequently in vaccinated individuals who contract Omicron and have less severe illness.”

Dr. Cohen serves as a consultant for Pfizer. Dr. Shah has disclosed no relevant financial relationships.

“Our findings showed that serious illness with hospitalization was associated with a higher rate of sequelae. It can therefore be inferred that the rates of sequelae seen in our study would continue to occur in unvaccinated individuals who contract Omicron, but might occur less frequently in vaccinated individuals who contract Omicron and have less severe illness.”

Dr. Cohen serves as a consultant for Pfizer. Dr. Shah has disclosed no relevant financial relationships.

Nearly one-third of adults over age 65 developed one or more new medical conditions in the weeks following a COVID-19 infection, according to new research.

The findings of the observational study, which were published in the BMJ, show the risk of a new condition being triggered by COVID is more than twice as high in seniors, compared with younger patients. Plus, the researchers observed an even higher risk among those who were hospitalized, with nearly half (46%) of patients having developed new conditions after the acute COVID-19 infection period.

Respiratory failure with shortness of breath was the most common postacute sequela, but a wide range of heart, kidney, lung, liver, cognitive, mental health, and other conditions were diagnosed at least 3 weeks after initial infection and persisted beyond 30 days.

This is one of the first studies to specifically describe the incidence and severity of new conditions triggered by COVID-19 infection in a general sample of older adults, said study author Ken Cohen MD, FACP, executive director of translational research at Optum Labs and national senior medical director at Optum Care.

“Much of what has been published on the postacute sequelae of COVID-19 has been predominantly from a younger population, and many of the patients had been hospitalized,” Dr. Cohen noted. “This was the first study to focus on a large population of seniors, most of whom did not require hospitalization.”

Dr. Cohen and colleagues reviewed the health insurance records of more than 133,000 Medicare beneficiaries aged 65 or older who were diagnosed with COVID-19 before April 2020. They also matched individuals by age, race, sex, hospitalization status, and other factors to comparison groups without COVID-19 (one from 2020 and one from 2019), and to a group diagnosed with other lower respiratory tract viral infections before the pandemic.
 

Risk of developing new conditions was higher in hospitalized

After acute COVID-19 infection, 32% of seniors sought medical care for at least one new medical condition in 2020, compared with 21% of uninfected people in the same year.

The most commonly observed conditions included:

  • Respiratory failure (7.55% higher risk).
  • Fatigue (5.66% higher risk).
  • High blood pressure (4.43% higher risk).
  • Memory problems (2.63% higher risk).
  • Kidney injury (2.59% higher risk).
  • Mental health diagnoses (2.5% higher risk).
  • Blood-clotting disorders (1.47 % higher risk).
  • Heart rhythm disorders (2.9% higher risk).

The risk of developing new conditions was even higher among those 23,486 who were hospitalized in 2020. Those individuals showed a 23.6% higher risk for developing at least one new condition, compared with uninfected seniors in the same year. Also, patients older than 75 had a higher risk for neurological disorders, including dementia, encephalopathy, and memory problems. The researchers also found that respiratory failure and kidney injury were significantly more likely to affect men and Black patients.

When those who had COVID were compared with the group with other lower respiratory viral infections before the pandemic, only the risks of respiratory failure (2.39% higher), dementia (0.71% higher), and fatigue (0.18% higher) were higher.

Primary care providers can learn from these data to better evaluate and manage their geriatric patients with COVID-19 infection, said Amit Shah, MD, a geriatrician with the Mayo Clinic in Phoenix, in an interview.

“We must assess older patients who have had COVID-19 for more than just improvement from the respiratory symptoms of COVID-19 in post-COVID follow-up visits,” he said. “Older individuals with frailty have vulnerability to subsequent complications from severe illnesses and it is common to see post-illness diagnoses, such as new diagnosis of delirium; dementia; or renal, respiratory, or cardiac issues that is precipitated by the original illness. This study confirms that this is likely the case with COVID-19 as well.

“Primary care physicians should be vigilant for these complications, including attention to the rehabilitation needs of older patients with longer-term postviral fatigue from COVID-19,” Dr. Shah added.
 

 

 

Data predates ‘Omicron wave’

It remains uncertain whether sequelae will differ with the Omicron variant, but the findings remain applicable, Dr. Cohen said.

“We know that illness from the Omicron variant is on average less severe in those that have been vaccinated. However, throughout the Omicron wave, individuals who have not been vaccinated continue to have significant rates of serious illness and hospitalization,” he said.

“Our findings showed that serious illness with hospitalization was associated with a higher rate of sequelae. It can therefore be inferred that the rates of sequelae seen in our study would continue to occur in unvaccinated individuals who contract Omicron, but might occur less frequently in vaccinated individuals who contract Omicron and have less severe illness.”

Heavy cannabis use tied to less diabetes in women

Article Type

Tue, 05/03/2022 - 15:02

Women who used marijuana (cannabis) at least four times in the previous month (heavy users) were less likely to have type 2 diabetes than women who were light users or nonusers, in a nationally representative U.S. observational study.

In contrast, there were no differences in the prevalence of type 2 diabetes in men who were light or heavy cannabis users versus nonusers.

These findings are based on data from the 2013-2018 National Health and Nutrition Examination Survey (NHANES), whereby participants self-reported their cannabis use.

The study by Ayobami S. Ogunsola, MD, MPH, a graduate student at Texas A&M University, College Station, and colleagues was recently published in Cannabis and Cannabinoid Research. 
 

What do the findings mean?

Although overall findings linking cannabis use and diabetes have been inconsistent, the gender differences in the current study are consistent with animal studies and some clinical studies, senior author Ibraheem M. Karaye, MD, MPH, said in an interview.

However, these gender differences need to be confirmed, and “we strongly recommend that more biological or biochemical studies be conducted that could actually tell us the mechanisms,” said Dr. Karaye, an assistant professor in the department of population health, Hofstra University, Hempstead, N.Y.

“It’s indisputable that medical marijuana has some medical benefits,” he added. “Women [who use cannabis] have been shown to lose more weight than men, for example.”

“If women [cannabis users] are less likely to develop diabetes or more likely to express improvement of symptoms of diabetes,” he noted, “this means that hyperglycemic medications that are being prescribed should be watched scrupulously. Otherwise, there is a risk that [women] may overrespond.”

That is, Dr. Karaye continued, women “may be at risk of developing hypoglycemia because the cannabis is acting synergistically with the regular drug that is being used to treat the diabetes.” 

U.S. clinicians, especially in states with legalized medical marijuana, need to be aware of the potential synergy.

“One would have to consider the patient as a whole,” he stressed. “For example, a woman that uses medical marijuana may actually respond differently to hyperglycemic medication.”
 

Conflicting reports explained by sex differences?

Evidence on whether cannabis use is linked with type 2 diabetes is limited and conflicting, the researchers wrote. They hypothesized that these conflicting findings might be explained by sex differences.

To “help inform current diabetes prevention and mitigation efforts,” they investigated sex differences in cannabis use and prevalence of type 2 diabetes in 15,602 men and women in the 2013-2014, 2015-2016, and 2017-2018 NHANES surveys.

Participants were classified as having type 2 diabetes if they had a physician’s diagnosis; a 2-hour plasma glucose of at least 200 mg/dL (in a glucose tolerance test); fasting blood glucose of at least 126 mg/dL; or A1c of at least 6.5%.

About half of respondents were women (52%) and close to half (44%) were age 18-39.

More than a third (38%) had a body mass index (BMI) of at least 30 kg/m2, indicating obesity.

Roughly 1 in 10 had a diagnosis of type 2 diabetes (13.5%) or A1c of at least 6.5% (9.8%).

Close to a fifth smoked cigarettes (16%). Similarly, 14.5% used cannabis at least four times a week, 3.3% used it less often, and the rest did not use it. Half of participants were not physically active (49%).

Just over half had at least a college education (55%).

Heavy cannabis users were more likely to be younger than age 40 (57% of men, 57% of women), college graduates (54% of men, 63% of women), cigarette smokers (79% of men, 83% of women), and physically inactive (39% of men, 49% of women).

Among women, heavy cannabis users were 49% less likely to have type 2 diabetes than nonusers, after adjusting for age, sex, race/ethnicity, educational level, physical activity, tobacco use, alcohol use, marital status, difficulty walking, employment status, income, and BMI (adjusted odds ratio, 0.51; 95% confidence interval, 0.31-0.84).

There were no significant differences between light cannabis users versus nonusers and diabetes prevalence in women, or between light or heavy cannabis users versus nonusers and diabetes prevalence in men.
 

 

 

Limitations, yet biologically plausible

The researchers acknowledged several study limitations.

They do not know how long participants had used marijuana. The men and women may have underreported their cannabis use, especially in states where medical marijuana was not legal, and the NHANES data did not specify whether the cannabis was recreational or medicinal.

The study may have been underpowered to detect a smaller difference in men who used versus did not use marijuana.

And importantly, this was an observational study (a snapshot at one point in time), so it cannot say whether the heavy cannabis use in women caused a decreased likelihood of diabetes.

Nevertheless, the inverse association between cannabis use and presence of type 2 diabetes is biologically plausible, Dr. Ogunsola and colleagues wrote.

The two major cannabis compounds, cannabidiol and delta-9-tetrahydrocannabinol, stimulate CBD1 and CBD2 receptors in the central and peripheral nervous systems, respectively. And “activation of the CBD1 receptor increases insulin secretion, glucagon, and somatostatin, and activates metabolic processes in fat and skeletal muscles – mechanisms that improve glucose disposal,” they explained.

The researchers speculated that the sex differences they found for this association may be caused by differences in sex hormones, or the endocannabinoid system, or fat deposits.

Therefore, “additional studies are needed to investigate the sex-based heterogeneity reported in this study and to elucidate potential mechanisms for the observation,” they concluded.

The study did not receive any funding and the researchers have no relevant financial disclosures.

Goffin’s cockatoo? More like golfin’ cockatoo

Can birds play golf? Of course not; it’s ridiculous. Humans can barely play golf, and we invented the sport. Anyway, moving on to “Brian retraction injury after elective aneurysm clipping.”

Hang on, we’re now hearing that a group of researchers, as part of a large international project comparing children’s innovation and problem-solving skills with those of cockatoos, have in fact taught a group of Goffin’s cockatoos how to play golf. Huh. What an oddly specific project. All right, fine, I guess we’ll go with the golf-playing birds.

Goffin Lab

Golf may seem very simple at its core. It is, essentially, whacking a ball with a stick. But the Scots who invented the game were undertaking a complex project involving combined usage of multiple tools, and until now, only primates were thought to be capable of utilizing compound tools to play games such as golf.

For this latest research, published in Scientific Reports, our intrepid birds were given a rudimentary form of golf to play (featuring a stick, a ball, and a closed box to get the ball through). Putting the ball through the hole gave the bird a reward. Not every cockatoo was able to hole out, but three did, with each inventing a unique way to manipulate the stick to hit the ball.

As entertaining as it would be to simply teach some birds how to play golf, we do loop back around to medical relevance. While children are perfectly capable of using tools, young children in particular are actually quite bad at using tools to solve novel solutions. Present a 5-year-old with a stick, a ball, and a hole, and that child might not figure out what the cockatoos did. The research really does give insight into the psychology behind the development of complex tools and technology by our ancient ancestors, according to the researchers.

We’re not entirely convinced this isn’t an elaborate ploy to get a bird out onto the PGA Tour. The LOTME staff can see the future headline already: “Painted bunting wins Valspar Championship in epic playoff.”
 

Work out now, sweat never

Okay, show of hands: Who’s familiar with “Name that tune?” The TV game show got a reboot last year, but some of us are old enough to remember the 1970s version hosted by national treasure Tom Kennedy.

Edith Cowan University

The contestants try to identify a song as quickly as possible, claiming that they “can name that tune in five notes.” Or four notes, or three. Well, welcome to “Name that exercise study.”

Senior author Masatoshi Nakamura, PhD, and associates gathered together 39 students from Niigata (Japan) University of Health and Welfare and had them perform one isometric, concentric, or eccentric bicep curl with a dumbbell for 3 seconds a day at maximum effort for 5 days a week, over 4 weeks. And yes, we did say 3 seconds.

“Lifting the weight sees the bicep in concentric contraction, lowering the weight sees it in eccentric contraction, while holding the weight parallel to the ground is isometric,” they explained in a statement on Eurekalert.

The three exercise groups were compared with a group that did no exercise, and after 4 weeks of rigorous but brief science, the group doing eccentric contractions had the best results, as their overall muscle strength increased by 11.5%. After a total of just 60 seconds of exercise in 4 weeks. That’s 60 seconds. In 4 weeks.

Big news, but maybe we can do better. “Tom, we can do that exercise in 2 seconds.”

And one! And two! Whoa, feel the burn.
 

 

 

Tingling over anxiety

Apparently there are two kinds of people in this world. Those who love ASMR and those who just don’t get it.

ASMR, for those who don’t know, is the autonomous sensory meridian response. An online community has surfaced, with video creators making tapping sounds, whispering, or brushing mannequin hair to elicit “a pleasant tingling sensation originating from the scalp and neck which can spread to the rest of the body” from viewers, Charlotte M. Eid and associates said in PLOS One.

The people who are into these types of videos are more likely to have higher levels of neuroticism than those who aren’t, which gives ASMR the potential to be a nontraditional form of treatment for anxiety and/or neuroticism, they suggested.

The research involved a group of 64 volunteers who watched an ASMR video meant to trigger the tingles and then completed questionnaires to evaluate their levels of neuroticism, trait anxiety, and state anxiety, said Ms. Eid and associates of Northumbria University in Newcastle-upon-Tyne, England.

The people who had a history of producing tingles from ASMR videos in the past had higher levels of anxiety, compared with those who didn’t. Those who responded to triggers also received some benefit from the video in the study, reporting lower levels of neuroticism and anxiety after watching, the investigators found.

Although people who didn’t have a history of tingles didn’t feel any reduction in anxiety after the video, that didn’t stop the people who weren’t familiar with the genre from catching tingles.

So if you find yourself a little high strung or anxious, or if you can’t sleep, consider watching a person pretending to give you a makeover or using fingernails to tap on books for some relaxation. Don’t knock it until you try it!
 

Living in the past? Not so far-fetched

It’s usually an insult when people tell us to stop living in the past, but the joke’s on them because we really do live in the past. By 15 seconds, to be exact, according to researchers from the University of California, Berkeley.

Mauro Manassi

But wait, did you just read that last sentence 15 seconds ago, even though it feels like real time? Did we just type these words now, or 15 seconds ago?

Think of your brain as a web page you’re constantly refreshing. We are constantly seeing new pictures, images, and colors, and your brain is responsible for keeping everything in chronological order. This new research suggests that our brains show us images from 15 seconds prior. Is your mind blown yet?

“One could say our brain is procrastinating. It’s too much work to constantly update images, so it sticks to the past because the past is a good predictor of the present. We recycle information from the past because it’s faster, more efficient and less work,” senior author David Whitney explained in a statement from the university.

It seems like the 15-second rule helps us not lose our minds by keeping a steady flow of information, but it could be a bit dangerous if someone, such as a surgeon, needs to see things with extreme precision.

And now we are definitely feeling a bit anxious about our upcoming heart/spleen/gallbladder replacement. … Where’s that link to the ASMR video?

The three exercise groups were compared with a group that did no exercise, and after 4 weeks of rigorous but brief science, the group doing eccentric contractions had the best results, as their overall muscle strength increased by 11.5%. After a total of just 60 seconds of exercise in 4 weeks. That’s 60 seconds. In 4 weeks.

Big news, but maybe we can do better. “Tom, we can do that exercise in 2 seconds.”

And one! And two! Whoa, feel the burn.
 

 

 

Tingling over anxiety

Apparently there are two kinds of people in this world. Those who love ASMR and those who just don’t get it.

ASMR, for those who don’t know, is the autonomous sensory meridian response. An online community has surfaced, with video creators making tapping sounds, whispering, or brushing mannequin hair to elicit “a pleasant tingling sensation originating from the scalp and neck which can spread to the rest of the body” from viewers, Charlotte M. Eid and associates said in PLOS One.

The people who are into these types of videos are more likely to have higher levels of neuroticism than those who aren’t, which gives ASMR the potential to be a nontraditional form of treatment for anxiety and/or neuroticism, they suggested.

The research involved a group of 64 volunteers who watched an ASMR video meant to trigger the tingles and then completed questionnaires to evaluate their levels of neuroticism, trait anxiety, and state anxiety, said Ms. Eid and associates of Northumbria University in Newcastle-upon-Tyne, England.

The people who had a history of producing tingles from ASMR videos in the past had higher levels of anxiety, compared with those who didn’t. Those who responded to triggers also received some benefit from the video in the study, reporting lower levels of neuroticism and anxiety after watching, the investigators found.

Although people who didn’t have a history of tingles didn’t feel any reduction in anxiety after the video, that didn’t stop the people who weren’t familiar with the genre from catching tingles.

So if you find yourself a little high strung or anxious, or if you can’t sleep, consider watching a person pretending to give you a makeover or using fingernails to tap on books for some relaxation. Don’t knock it until you try it!
 

Living in the past? Not so far-fetched

It’s usually an insult when people tell us to stop living in the past, but the joke’s on them because we really do live in the past. By 15 seconds, to be exact, according to researchers from the University of California, Berkeley.

Mauro Manassi

But wait, did you just read that last sentence 15 seconds ago, even though it feels like real time? Did we just type these words now, or 15 seconds ago?

Think of your brain as a web page you’re constantly refreshing. We are constantly seeing new pictures, images, and colors, and your brain is responsible for keeping everything in chronological order. This new research suggests that our brains show us images from 15 seconds prior. Is your mind blown yet?

“One could say our brain is procrastinating. It’s too much work to constantly update images, so it sticks to the past because the past is a good predictor of the present. We recycle information from the past because it’s faster, more efficient and less work,” senior author David Whitney explained in a statement from the university.

It seems like the 15-second rule helps us not lose our minds by keeping a steady flow of information, but it could be a bit dangerous if someone, such as a surgeon, needs to see things with extreme precision.

And now we are definitely feeling a bit anxious about our upcoming heart/spleen/gallbladder replacement. … Where’s that link to the ASMR video?

 

Goffin’s cockatoo? More like golfin’ cockatoo

Can birds play golf? Of course not; it’s ridiculous. Humans can barely play golf, and we invented the sport. Anyway, moving on to “Brian retraction injury after elective aneurysm clipping.”

Hang on, we’re now hearing that a group of researchers, as part of a large international project comparing children’s innovation and problem-solving skills with those of cockatoos, have in fact taught a group of Goffin’s cockatoos how to play golf. Huh. What an oddly specific project. All right, fine, I guess we’ll go with the golf-playing birds.

Goffin Lab

Golf may seem very simple at its core. It is, essentially, whacking a ball with a stick. But the Scots who invented the game were undertaking a complex project involving combined usage of multiple tools, and until now, only primates were thought to be capable of utilizing compound tools to play games such as golf.

For this latest research, published in Scientific Reports, our intrepid birds were given a rudimentary form of golf to play (featuring a stick, a ball, and a closed box to get the ball through). Putting the ball through the hole gave the bird a reward. Not every cockatoo was able to hole out, but three did, with each inventing a unique way to manipulate the stick to hit the ball.

As entertaining as it would be to simply teach some birds how to play golf, we do loop back around to medical relevance. While children are perfectly capable of using tools, young children in particular are actually quite bad at using tools to solve novel solutions. Present a 5-year-old with a stick, a ball, and a hole, and that child might not figure out what the cockatoos did. The research really does give insight into the psychology behind the development of complex tools and technology by our ancient ancestors, according to the researchers.

We’re not entirely convinced this isn’t an elaborate ploy to get a bird out onto the PGA Tour. The LOTME staff can see the future headline already: “Painted bunting wins Valspar Championship in epic playoff.”
 

Work out now, sweat never

Okay, show of hands: Who’s familiar with “Name that tune?” The TV game show got a reboot last year, but some of us are old enough to remember the 1970s version hosted by national treasure Tom Kennedy.

Edith Cowan University

The contestants try to identify a song as quickly as possible, claiming that they “can name that tune in five notes.” Or four notes, or three. Well, welcome to “Name that exercise study.”

Senior author Masatoshi Nakamura, PhD, and associates gathered together 39 students from Niigata (Japan) University of Health and Welfare and had them perform one isometric, concentric, or eccentric bicep curl with a dumbbell for 3 seconds a day at maximum effort for 5 days a week, over 4 weeks. And yes, we did say 3 seconds.

“Lifting the weight sees the bicep in concentric contraction, lowering the weight sees it in eccentric contraction, while holding the weight parallel to the ground is isometric,” they explained in a statement on Eurekalert.

The three exercise groups were compared with a group that did no exercise, and after 4 weeks of rigorous but brief science, the group doing eccentric contractions had the best results, as their overall muscle strength increased by 11.5%.

Chronic marijuana use linked to recurrent stroke

Article Type
Changed
Mon, 02/28/2022 - 15:37

Young adults hospitalized for a stroke are much more likely to be admitted for a recurrent stroke if they have cannabis use disorder, new observational research suggests. “Our analysis shows young marijuana users with a history of stroke or transient ischemic attack remain at significantly high risk for future strokes,” said lead study author Akhil Jain, MD, a resident physician at Mercy Fitzgerald Hospital in Darby, Pennsylvania.

“It’s essential to raise awareness among young adults about the impact of chronic habitual use of marijuana, especially if they have established cardiovascular risk factors or previous stroke.”

The study will be presented during the International Stroke Conference, presented by the American Stroke Association, a division of the American Heart Association.

An increasing number of jurisdictions are allowing marijuana use. To date, 18 states and the District of Columbia have legalized recreational cannabis use, the investigators noted.

Research suggests cannabis use disorder – defined as the chronic habitual use of cannabis – is more prevalent in the young adult population. But Dr. Jain said the population of marijuana users is “a changing dynamic.”

Cannabis use has been linked to an increased risk for first-time stroke or transient ischemic attack (TIA). Traditional stroke risk factors include hypertension, diabetes, and diseases related to blood vessels or blood circulation, including atherosclerosis.

Young adults might have additional stroke risk factors, such as behavioral habits like substance abuse, low physical activity, and smoking, oral contraceptives use among females, and brain infections, especially in the immunocompromised, said Dr. Jain.

Research from the American Heart Association shows stroke rates are increasing among adults 18 to 45 years of age. Each year, young adults account for up to 15% of strokes in the United States.

Prevalence and risk for recurrent stroke in patients with previous stroke or TIA in cannabis users have not been clearly established, the researchers pointed out.

A higher rate of recurrent stroke

For this new study, Dr. Jain and colleagues used data from the National Inpatient Sample from October 2015 to December 2017. They identified hospitalizations among young adults 18 to 45 years of age with a previous history of stroke or TIA.

They then grouped these patients into those with cannabis use disorder (4,690) and those without cannabis use disorder (156,700). The median age in both cohorts was 37 years.

The analysis did not include those who were considered in remission from cannabis use disorder.

Results showed that 6.9% of those with cannabis use disorder were hospitalized for a recurrent stroke, compared with 5.4% of those without cannabis use disorder (P < .001).

After adjustment for demographic factors (age, sex, race, household income), and pre-existing conditions, patients with cannabis use disorder were 48% more likely to be hospitalized for recurrent stroke than those without cannabis use disorder (odds ratio, 1.48; 95% confidence interval, 1.28-1.71; P < .001).

Compared with the group without cannabis use disorder, the cannabis use disorder group had more men (55.2% vs. 40.2%), more African American people (44.6% vs. 37.2%), and more use of tobacco (73.9% vs. 39.6%) and alcohol (16.5% vs. 3.6%). They also had a greater percentage of chronic obstructive pulmonary disease, depression, and psychoses.

But a smaller percentage of those with cannabis use disorder had hypertension (51.3% vs. 55.6%; P = .001) and diabetes (16.3% vs. 22.7%; P < .001), which is an “interesting” finding, said Dr. Jain.

“We observed that even with a lower rate of cardiovascular risk factors, after controlling for all the risk factors, we still found the cannabis users had a higher rate of recurrent stroke.”

He noted this was a retrospective study without a control group. “If both groups had comparable hypertension, then this risk might actually be more evident,” said Dr. Jain. “We need a prospective study with comparable groups.”

Living in low-income neighborhoods and in northeast and southern regions of the United States was also more common in the cannabis use disorder group.
 

 

 

Hypothesis-generating research

The study did not investigate the possible mechanisms by which marijuana use might increase stroke risk, but Dr. Jain speculated that these could include factors such as impaired blood vessel function, changes in blood supply, an increased tendency of blood clotting, impaired energy production in brain cells, and an imbalance between molecules that harm healthy tissue and the antioxidant defenses that neutralize them.

As cannabis use may pose a different risk for a new stroke, as opposed a previous stroke, Dr. Jain said it would be interesting to study the amount of “residual function deficit” experienced with the first stroke.

The new study represents “foundational research” upon which other research teams can build, said Dr. Jain. “Our study is hypothesis-generating research for a future prospective randomized controlled trial.”

A limitation of the study is that it did not consider the effect of various doses, duration, and forms of cannabis abuse, or use of medicinal cannabis or other drugs.

Robert L. Page II, PharmD, professor, departments of clinical pharmacy and physical medicine/rehabilitation, University of Colorado Skaggs School of Pharmacy and Pharmaceutical Sciences, Aurora, provided a comment on this new research.

A cannabis use disorder diagnosis provides “specific criteria” with regard to chronicity of use and reflects “more of a physical and psychological dependence upon cannabis,” said Dr. Page, who chaired the writing group for the AHA 2020 cannabis and cardiovascular disease scientific statement.

He explained what sets people with cannabis use disorder apart from “run-of-the-mill” recreational cannabis users is that “these are individuals who use a cannabis product, whether it’s smoking it, vaping it, or consuming it via an edible, and are using it on a regular basis, in a chronic fashion.”

The study received no outside funding. The authors report no relevant disclosures.

Substantial numbers of U.S. youth report vaping cannabis

Article Type
Changed
Thu, 02/10/2022 - 08:19

Adolescents and young adults who use e-cigarettes reported vaping cannabis, according to selected data from the national Population Assessment of Tobacco and Health (PATH) study.

Ruoyan Sun, PhD, an assistant professor at the University of Alabama at Birmingham, and colleagues examined results of PATH’s wave5 survey conducted from December 2018 to November 2019. PATH is a National Institutes of Health–Food and Drug Administration collaboration begun in 2013.

Dr. Ruoyan Sun

Their analysis, published online Feb. 7, 2022, in JAMA Pediatrics, evaluated the frequency of cannabis vaping across several age groups: 164 respondents ages 12-14; 919 participants ages 15-17; and 3,038 participants ages 18-24. Respondents included for analysis reported electronic nicotine product consumption in the past 30 days. In response to the question “When you have used an electronic product, how often were you using it to smoke marijuana, marijuana concentrates, marijuana waxes, THC, or hash oils?” 35.0% (95% confidence interval, 29.3%-41.2%) of current e-smokers aged 12-14 years said they had done so, as did 51.3% (95% CI, 47.7%-54.9%) of those aged 15-17 years and 54.6% (95% CI, 52.5%-56.7%) of young adults aged 18-24.

The prevalence of those who reported vaping cannabis every time they vaped was 3.1% (95% CI, 1.3%-6.9%) of youths aged 12-14 years, 6.7% (95% CI, 5.3%-8.6%) of youths aged 15-17 years, and 10.3% (95% CI, 9.0%-11.6%) of young adults aged 18-24.

Among children ages 12-14, 65% said they never vaped cannabis, while 48.7% and 45.4%, respectively, in the two older groups said they did.

“This is a very important finding and it mirrors what some of us have already seen in practice,” said pediatric pulmonologist S. Christy Sadreameli, MD, MHS, an assistant professor of pediatrics at John Hopkins University, Baltimore. “It is important for pediatricians to realize that dual use of cannabis and nicotine vaping, and exclusive use of cannabis vaping, are not uncommon. It informs how we ask questions and how we counsel our patients.” Dr. Sadreameli was not involved in the PATH study.

Overall, the survey participants were 56% male, with 24% of respondents identifying as Hispanic, 8% as non-Hispanic Black, 58% as non-Hispanic White, and 10% as of other race/ethnicity. The weighted proportion of current e-cigarette use was 3.0% (95% CI, 2.6%-3.4%) in youths ages 12-14 years, 14.4% (95% CI, 13.5%-15.3%) in those 15-17 years, and 26.2% (95% CI, 25.3%-27.1%) in young adults.

Other recent national surveys such as the National Institute on Drug Abuses’s Monitoring the Future are reporting a growing prevalence of youth cannabis vaping, Dr. Sun said. For example, the prevalence of cannabis vaping in the past 12-month period among grade 12 students grew from 9.5% in 2017 to 22.1% in 2020. Vaping cannabis was more prevalent among Hispanic teens than other ethnicities.

Vaping devices such as e-cigarettes, vaping pens, e-cigars, and e-hookahs can be used to inhale multiple substances, including nicotine, cannabis, and opium, Dr. Sun noted in an interview. “So in addition to asking about the behavior of vaping itself, pediatricians could pay more attention to what is being vaped in these devices.”

Dr. S. Christy Sadreameli

According to Dr. Sadreameli, vaping more than one substance at a time could potentially work synergistically to cause more harm, compared with one product alone. “The other aspect to consider is that vaping multiple types of products may increase the chance of harm from other components of the mixture,” she said. For instance, a lot of the e-cigarette or vaping use-associated lung injury (EVALI) cases have been linked to vitamin E acetate, which was found in certain cannabis formulations. “Anecdotally, most EVALI patients I’ve met seemed to report use of multiple products, including cannabis-containing and nicotine-containing products.”

Dr. Sadreameli added that some cannabis vapers will have other issues. “For example, there is a severe vomiting syndrome I’ve seen, which is induced by cannabis and improved by cessation from cannabis,” she said. “It is important for pediatricians to ask the right questions of their patients in order to better understand what they may be experiencing, provide counseling, and to help them.”

A related issue is cessation, she said. “For those working to achieve cessation from nicotine-based products, sometimes nicotine replacement therapies are helpful. However, cessation from cannabis-containing products is going to look different.”

Although the study did not yield information on the prevalence simultaneous nicotine/cannabis vaping, the authors suggested that some vapers may be combining substances. Previous studies may have modestly overestimated the prevalence of nicotine vaping given their finding that some current e-cigarette users reported vaping cannabis every time they vaped and may be vaping cannabis exclusively. “However, if some current users vaped nicotine and cannabis simultaneously, then overestimation of nicotine vaping would be smaller,” they wrote.

Future surveys on this area should contain detailed questions on nicotine and cannabis vaping, including the substance being vaped and the frequency and intensity of use, Dr. Sun said. “In addition, these surveys could examine some other substances that are being vaped, such as opium and cocaine.”

The PATH study is supported by the NIH, National Institute on Drug Abuse, Department of Health & Human Services, and the FDA’s Center for Tobacco Products. The authors and Dr. Sadreameli had no competing interests to disclose.

Adolescents and young adults who use e-cigarettes reported vaping cannabis, according to selected data from the national Population Assessment of Tobacco and Health (PATH) study.

Ruoyan Sun, PhD, an assistant professor at the University of Alabama at Birmingham, and colleagues examined results of PATH’s wave5 survey conducted from December 2018 to November 2019. PATH is a National Institutes of Health–Food and Drug Administration collaboration begun in 2013.

Dr. Ruoyan Sun

Their analysis, published online Feb. 7, 2022, in JAMA Pediatrics, evaluated the frequency of cannabis vaping across several age groups: 164 respondents ages 12-14; 919 participants ages 15-17; and 3,038 participants ages 18-24. Respondents included for analysis reported electronic nicotine product consumption in the past 30 days. In response to the question “When you have used an electronic product, how often were you using it to smoke marijuana, marijuana concentrates, marijuana waxes, THC, or hash oils?” 35.0% (95% confidence interval, 29.3%-41.2%) of current e-smokers aged 12-14 years said they had done so, as did 51.3% (95% CI, 47.7%-54.9%) of those aged 15-17 years and 54.6% (95% CI, 52.5%-56.7%) of young adults aged 18-24.

The prevalence of those who reported vaping cannabis every time they vaped was 3.1% (95% CI, 1.3%-6.9%) of youths aged 12-14 years, 6.7% (95% CI, 5.3%-8.6%) of youths aged 15-17 years, and 10.3% (95% CI, 9.0%-11.6%) of young adults aged 18-24.

Among children ages 12-14, 65% said they never vaped cannabis, while 48.7% and 45.4%, respectively, in the two older groups said they did.

“This is a very important finding and it mirrors what some of us have already seen in practice,” said pediatric pulmonologist S. Christy Sadreameli, MD, MHS, an assistant professor of pediatrics at John Hopkins University, Baltimore. “It is important for pediatricians to realize that dual use of cannabis and nicotine vaping, and exclusive use of cannabis vaping, are not uncommon. It informs how we ask questions and how we counsel our patients.” Dr. Sadreameli was not involved in the PATH study.

Overall, the survey participants were 56% male, with 24% of respondents identifying as Hispanic, 8% as non-Hispanic Black, 58% as non-Hispanic White, and 10% as of other race/ethnicity. The weighted proportion of current e-cigarette use was 3.0% (95% CI, 2.6%-3.4%) in youths ages 12-14 years, 14.4% (95% CI, 13.5%-15.3%) in those 15-17 years, and 26.2% (95% CI, 25.3%-27.1%) in young adults.

Other recent national surveys such as the National Institute on Drug Abuses’s Monitoring the Future are reporting a growing prevalence of youth cannabis vaping, Dr. Sun said. For example, the prevalence of cannabis vaping in the past 12-month period among grade 12 students grew from 9.5% in 2017 to 22.1% in 2020. Vaping cannabis was more prevalent among Hispanic teens than other ethnicities.

Vaping devices such as e-cigarettes, vaping pens, e-cigars, and e-hookahs can be used to inhale multiple substances, including nicotine, cannabis, and opium, Dr. Sun noted in an interview. “So in addition to asking about the behavior of vaping itself, pediatricians could pay more attention to what is being vaped in these devices.”

Dr. S. Christy Sadreameli

According to Dr. Sadreameli, vaping more than one substance at a time could potentially work synergistically to cause more harm, compared with one product alone. “The other aspect to consider is that vaping multiple types of products may increase the chance of harm from other components of the mixture,” she said. For instance, a lot of the e-cigarette or vaping use-associated lung injury (EVALI) cases have been linked to vitamin E acetate, which was found in certain cannabis formulations. “Anecdotally, most EVALI patients I’ve met seemed to report use of multiple products, including cannabis-containing and nicotine-containing products.”

Dr. Sadreameli added that some cannabis vapers will have other issues. “For example, there is a severe vomiting syndrome I’ve seen, which is induced by cannabis and improved by cessation from cannabis,” she said. “It is important for pediatricians to ask the right questions of their patients in order to better understand what they may be experiencing, provide counseling, and to help them.”

Brain imaging gives new insight into hoarding disorder

Article Type
Changed
Wed, 02/09/2022 - 12:19

Widespread white matter (WM) abnormalities may offer new insight into hoarding disorder (HD).

In a neuroimaging study, investigators led by Taro Mizobe, department of neuropsychiatry, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan, compared brain scans of individuals with and without HD.

Results showed that compared with healthy family members, participants with HD had anatomically widespread abnormalities in WM tracts.

In particular, a broad range of alterations were found in frontal WM related to HD symptom severity, as well as cortical regions involved in cognitive dysfunction.

“The finding of a characteristic association between alterations in the prefrontal WM tract, which connects cortical regions involved in cognitive function and the severity of hoarding symptoms, could provide new insights into the neurobiological basis of HD,” the researchers write.

The findings were published online Jan. 18 in the Journal of Psychiatric Research.
 

Limited information to date

“Although there are no clear neurobiological models of HD, several neuroimaging studies have found specific differences in specific brain regions” between patients with and without HD, the investigators write.

Structural MRI studies and voxel-based morphometry have shown larger volumes of gray matter in several regions of the brain in patients with HD. However, there have been no reports on alterations in the WM tracts – and studies of patients with obsessive-compulsive disorder and hoarding symptoms have yielded only “limited information” regarding WM tracts, the researchers note.

Diffusion tensor imaging (DTI) studies have yielded “inconsistent” findings, “therefore little is known about the microstructure of WM in the brains of patients with HD,” they add.

The current study was designed “to investigate microstructural alterations in the WM tracts of individuals with HD” by using tract-based spatial statistics – a model typically used for whole-brain, voxel-wise analysis of DTI measures.

DTI neuroimaging can assess the microstructure of WM. In the current study, the investigators focused on the three measures yielded by DTI: fractional anisotropy (FA), which is an index of overall WM integrity; axial diffusivity (AD); and radial diffusivity (RD).

Participants underwent MRI and DTI scans. Brain images of 25 individuals with hoarding disorder (mean age, 43 years; 64% women; 96% right-handed) were compared with those of 36 healthy controls matched for age, sex, and handedness.

Participants with HD had higher scores on the Hamilton Rating Scales for depression and anxiety than those without HD (P < .001 for both).

Of the patients with HD, 10 were taking psychiatric medications such as antidepressants, tranquilizers, or nonstimulant agents for attention-deficit/hyperactivity disorder.

Most (n = 18) were concurrently diagnosed with other psychiatric conditions, including ADHD, anxiety disorder, major depressive disorder, posttraumatic stress disorder, or obsessive-compulsive disorder.

The researchers also conducted a post hoc analysis of regions of interest “to detect correlations with clinical features.”
 

Microstructural alterations

Compared with healthy controls, patients with hoarding disorder showed decreased FA and increased RD in anatomically widespread WM tracts.

Decreased FA areas included the left superior longitudinal fasciculus (SLF), left uncinate fasciculus, left inferior fronto-occipital fasciculus (IFOF), left anterior thalamic radiation (ATR), left corticospinal tract, and left anterior limb of the internal capsule (ALIC).

Increased RD areas included the bilateral SLF, right IFOF, bilateral anterior and superior corona radiata, left posterior corona radiata, right ATR, left posterior thalamic radiation, right external capsule, and right ALIC.

Post hoc analyses of “regions of interest,” revealed “significant negative correlation” between the severity of hoarding symptoms and FA, particularly in the left anterior limb of the internal capsule, and a positive correlation between HD symptom severity and radial diffusivity in the right anterior thalamic radiation.

Those with HD also showed “a broad range of alterations” in the frontal WM tracts, including the frontothalamic circuit, frontoparietal network, and frontolimbic pathway.

“We found anatomically widespread decreases in FA and increases in WD in many major WM tracts and correlations between the severity of hoarding symptoms and DTI parameters (FA and RD) in the left ALIC and right ATR, which is part of the frontothalamic circuit,” the investigators write.

These findings “suggest that patients with HD have microstructural alterations in the prefrontal WM tracts,” they add.
 

 

 

First study

The researchers say that, to their knowledge, this is the first study to find major abnormalities in WM tracts within the brain and correlations between DTI indexes and clinical features in patients with HD.

The frontothalamic circuit is “thought to play an important role in executive functions, including working memory, attention, reward processing, and decision-making,” the investigators write.

Previous research implied that frontothalamic circuit–related cognitive functions are “impaired in patients with HD” and suggested that these impairments “underlie hoarding symptoms such as acquiring, saving, and cluttering relevant to HD.”

The decreased FA in the left SLF “reflects alterations in WM in the frontoparietal network in these patients and may be associated with cognitive impairments, such as task switching and inhibition, as shown in previous studies,” the researchers write.

Additionally, changes in FA and RD often “indicate myelin pathology,” which suggest that HD pathophysiology “may include abnormalities of myelination.”

However, the investigators cite several study limitations, including the “relatively small” sample size, which kept the DTI analysis from being “robust.” Moreover, many patients with HD had comorbid psychiatric disorders, which have also been associated with microstructural abnormalities in WM, the researchers note.
 

Novel approach

Commenting for this news organization, Michael Stevens, PhD, director, CNDLAB, Olin Neuropsychiatry Research Center, and adjunct professor of psychiatry at Yale University School of Medicine, New Haven, Conn., said the study “provides useful new clues for understanding HD neurobiology” because of its novel approach in assessing microstructural properties of major WM tracts.

The study’s “main contribution is to identify specific WM pathways between brain regions as worth looking at closely in the future. Some of these regions already have been implicated by brain function neuroimaging as abnormal in patients who compulsively hoard,” said Dr. Stevens, who was not involved in the research.

He noted that, when WM pathway integrity is affected, “it is thought to have an impact on how well information is communicated” between the brain regions.

“So once these specific findings are replicated in a separate study, they hopefully can guide researchers to ask new questions to learn exactly how these WM tracts might contribute to hoarding behavior,” Dr. Stevens said.

The study had no specific funding. The investigators and Dr. Stevens have disclosed no relevant financial relationships.

Potential new neuromodulation treatment for migraines

Article Type
Changed
Thu, 02/10/2022 - 08:23

Most people avoid smartphones when they have a migraine headache, but a noninvasive treatment for episodic migraines may change that.

A smartphone-enabled device, cleared by the Food and Drug Administration in early 2021, uses technology to trick the brain into releasing the neurotransmitters serotonin and noradrenaline that can help ease migraine pain.

Tina Montgomery, 58, has suffered from migraines since childhood and spent years looking for something to help manage them. Doctors consider her a “chronic” sufferer in that she has more than 14 migraines a month (fewer than 14 is considered “episodic”). Prescription antidepressants, anticonvulsants, and botulinum toxin shots as preventive treatments helped a little but not enough.

A few years ago, she found some relief using a new preventive injectable medication that targets a peptide known as CGRP, combined with an oral CGRP rescue medication, ubrogepant (Ubrelvy). However, by early 2021, Ms. Montgomery’s chronic migraines were back as she faced stress from the pandemic and her role as a caregiver for her aging parents.

“I was going through so much medication. I just didn’t feel good taking so much,” she said.

Looking for relief, she read about Nerivio, a wearable migraine treatment device that uses remote electrical neuromodulation (REN). She mentioned the device to her neurologist, and he agreed she might benefit from trying it out. Today, she uses the device whenever she feels a migraine may be imminent, she said.

“It really helps me stave off migraines I feel coming on and the milder ones where I would normally hesitate to use prescription medication because [insurance] limits the number of pills they give you in a month,” she said. “I follow through with the Nerivio treatment and usually find that my migraine doesn’t fully develop or is completely gone, and I don’t get a migraine at all.”
 

Taking it on the arm

The device works by stimulating nerves at the back of the arm right around the triceps. “Those nerve fibers relay information to the brain stem [so it can] work its magic and use the brain’s own natural mechanisms for reducing pain,” said Brian M. Grosberg, MD, director of the Hartford Healthcare Ayer Neuroscience Institute Headache Center, West Hartford, Conn.  

These mechanisms are like a bait-and-switch for the brain, said Britany Klenofsky, MD, assistant professor of neurology, Icahn School of Medicine at Mount Sinai, New York. “You’re trying to stimulate pain somewhere else [on the body] to tell the brain to protect itself and release [the neurotransmitter] serotonin,” she said. “You do this by putting the device on your arm, an area that’s away from the head where the pain is actively occurring, turning the device on, and increasing the stimulation to a nearly painful stimulus.”

This pseudo pain prompts the brain to release serotonin, the feel-good hormone along with norepinephrine and noradrenaline. The device works best when it’s used as soon as a migraine starts, so patients should hook up Nerivio within the first 20-30 minutes of onset of pain, said Dr. Grosberg, who was an investigator on the double-blind treatment study that led to FDA clearance. If patients wait too long, the device may not work.

This is why as soon as Ms. Montgomery feels a migraine aura (there are six types of migraine auras, including visual changes and muscle weakness) that occurs right before a migraine strikes, she puts the device armband on her upper arm and launches its smartphone app. Then she turns on the device for a 45-minute treatment, which begins with what she characterizes as tingling and vibration sensations on her arm. She turns up the intensity of the sensations, which are mild electric currents, until they are well-felt but not painful.

Ms. Montgomery said she can use the device and multitask since there’s no need for her to lie down or sit in a darkened room. And since it is worn on the arm, she can wear it under a shirtsleeve while working or out in public without anyone noticing. She also uses the app’s migraine diary and guided meditation to help reduce the anxiety that often accompanies her migraines.

The device is approved for adolescents and adults and can be used for both episodic and chronic migraines. From an efficacy standpoint, the device provides relief about as well as a commonly used pharmaceutical class of drugs, triptans. About 37% of people with episodic migraine achieved complete freedom from pain 2 hours after their treatment. In addition, about two-thirds of people reported pain relief after 2 hours, which is better success than people find with many prescription and nonprescription drugs.

A separate study looked at acute treatment for chronic migraine sufferers and found nearly 60% of people using the device found relief and 21% said they were pain-free after 2 hours. Almost two-thirds of those who experienced pain relief were pain-free 24 hours after the treatment.
 

 

 

Finding the perfect patient

There are other FDA-cleared noninvasive devices to treat migraines. One device, CEFALY, is an external trigeminal nerve stimulation device that sits on the forehead. Another device, SpringTMS, uses transcranial magnetic stimulation on the back of the head. A third option, the gammaCore Sapphire, is placed on the neck to stimulate the vagus nerve. All three have been cleared by the FDA to work as preventive and acute treatments for migraine.

Theranica, the company that developed Nerivio, is trying to boost use of the device by allowing patients to get a prescription via telehealth visits with a physician.

The company, as well as the companies behind the other neuromodulation devices, are marketing their treatments to children ages 12 and up since nonpharmacologic options are often preferable for parents, said Thomas Berk, MD, a clinical associate professor in the division of headache at NYU Langone Health in New York.

Dr. Berk said the devices could be appealing for those people who don’t want or can’t take medication, such as pregnant women or those who don’t respond well to drugs. “[They] could also be used by somebody who needs something in addition to a medication,” he said.

For now, people like Ms. Montgomery say they are happy to have another tool in their migraine arsenal. “Overall, I’m taking less medication because I haven’t had to have my Ubrelvy refilled as often as I used to,” she said. “It’s really helped me manage changes and stresses in my life.”
