Mounting evidence suggests selective serotonin reuptake inhibitors (SSRI) are associated with lower COVID-19 severity.

A large analysis of health records shows patients with COVID-19 taking an SSRI were significantly less likely to die of COVID-19 than a matched control group.

Data-driven approach

Investigators analyzed data from the Cerner Real World Data COVID-19 deidentified electronic health records database of 490,373 patients with COVID-19 across 87 health centers, including 3,401 patients who were prescribed SSRIs.

When compared with matched patients with COVID-19 taking SSRIs, patients taking fluoxetine were 28% less likely to die (relative risk, 0.72; 95% CI, 0.54-0.97; adjusted P = .03) and those taking either fluoxetine or fluvoxamine were 26% less likely to die (RR, 0.74; 95% CI, 0.55-0.99; adjusted P = .04) versus those not on these medications.

Patients with COVID-19 taking any kind of SSRI were 8% less likely to die than the matched controls (RR, 0.92; 95% CI, 0.85-0.99; adjusted P = .03).

“We observed a statistically significant reduction in mortality of COVID-19 patients who were already taking SSRIs. This is a demonstration of a data-driven approach for identifying new uses for existing drugs,” Dr. Sirota said in an interview.

“Our study simply shows an association between SSRIs and COVID-19 outcomes and doesn’t investigate the mechanism of action of why the drugs might work. Additional clinical trials need to be carried out before these drugs can be used in patients going forward,” she cautioned.

“There is currently an open-label trial investigating fluoxetine to reduce intubation and death after COVID-19. To our knowledge, there are no phase 3 randomized controlled trials taking place or planned,” study investigator Tomiko Oskotsky, MD, with UCSF, told this news organization.

Urgent need

The current results “confirm and expand on prior findings from observational, preclinical, and clinical studies suggesting that certain SSRI antidepressants, including fluoxetine or fluvoxamine, could be beneficial against COVID-19,” Nicolas Hoertel, MD, PhD, MPH, with Paris University and Corentin-Celton Hospital, France, writes in a linked editorial.

Dr. Hoertel notes that the anti-inflammatory properties of SSRIs may underlie their potential action against COVID-19, and other potential mechanisms may include reduction in platelet aggregation, decreased mast cell degranulation, increased melatonin levels, interference with endolysosomal viral trafficking, and antioxidant activities.

“Because most of the world’s population is currently unvaccinated and the COVID-19 pandemic is still active, effective treatments of COVID-19 – especially those that are easy to use, show good tolerability, can be administered orally, and have widespread availability at low cost to allow their use in resource-poor countries – are urgently needed to reduce COVID-19-related mortality and morbidity,” Dr. Hoertel points out.

“In this context, short-term use of fluoxetine or fluvoxamine, if proven effective, should be considered as a potential means of reaching this goal,” he adds.

The study was supported by the Christopher Hess Research Fund and, in part, by UCSF and the National Institutes of Health. Dr. Sirota has reported serving as a scientific advisor at Aria Pharmaceuticals. Dr. Hoertel has reported being listed as an inventor on a patent application related to methods of treating COVID-19, filed by Assistance Publique-Hopitaux de Paris, and receiving consulting fees and nonfinancial support from Lundbeck.

When parents of children with autism spectrum disorder (ASD) participating in the largest clinical trial of intranasal oxytocin to date came in for follow-up visits with investigators, they reported marked improvement in the children’s social functioning.

Kids who rarely communicated with their families began to interact more. Those who usually preferred to isolate themselves started joining their parents for meals. It all seemed so promising – until the data came in.

“Those sounded like real improvements to me, and it seemed like they increased over the period of the study,” lead investigator Linmarie Sikich, MD, an associate clinical professor of psychiatry with Duke University School of Medicine and the Duke Center for Autism and Brain Development, Durham, N.C., told this news organization. “Turns out it wasn’t oxytocin that was making that difference.”

Researchers found that after 24 weeks of daily treatment with intranasal oxytocin, there were no significant differences in social functioning between children who received active treatment and those in the placebo group.

The much-anticipated results were published online in The New England Journal of Medicine. To say that they are disappointing, Dr. Sikich said, is an understatement.
 

Increase in off-label use

Most studies in mouse models of ASD and small trials in children produced conflicting results, although there were modest improvements in social functioning associated with the use of intranasal oxytocin. Some clinicians were already prescribing it off label.

On the basis of this research and early feedback from parents of children, Dr. Sikich and colleagues were hopeful.

However, results from a rigorous, 5-year, $11.4 million randomized trial were negative. Yet, parents were convinced their child improved during the study, and there was a significant increase in off-label prescribing of a treatment her research says doesn’t work. What’s next for oxytocin?

Known as the “love hormone,” oxytocin is a neurotransmitter that is primarily synthesized in the hypothalamus. It plays a role in childbirth and lactation and is also involved in the regulation of social functioning and emotions. Research suggests low oxytocin levels are associated with diminished social functioning, regardless of ASD status.

Its potential as an autism therapy for children has been under study for a decade. Some findings link its use to improvements in core deficits associated with ASD, including repetitive behaviors, fixated or restricted interest, and social communication. A study published in 2020 showed that the treatment improved symptoms in high-functioning adults with ASD.

These were mostly small studies and were underpowered to reliably detect an effect of the therapy on social functioning. They often involved only a single dose of oxytocin. Some studies showed improvements, but others did not.

Still, interest in the treatment grew. Physicians began prescribing it for children with ASD, and parents began buying products containing oxytocin on the internet. Researchers feared this off-label use was becoming widespread, despite inconclusive evidence of efficacy.
 

High hopes

With support from a National Institutes of Health grant, Dr. Sikich and her team designed a phase 2, multicenter, randomized, double-blind, placebo-controlled study to determine whether the use of oxytocin in children with ASD works and is safe.

The challenges began before they even enrolled a single child. A number of behavioral assessment tools are used to measure social function in ASD, but there is no consensus on which one is best.

A simple blood test could determine how much oxytocin from the nasal spray was absorbed in the blood, but identifying how much made it to the brain would require fMRI, which is expensive and is challenging to use in this study population. Then there was the acquisition of the drug itself.

The Food and Drug Administration has approved intravenous oxytocin for inducing labor. Intranasal oxytocin is not approved for any indication and isn’t available commercially in the United States. Patients or researchers must secure the drug from a manufacturer in a country where it is approved or order it from a U.S. pharmacy that is capable of compounding IV oxytocin into an intranasal formulation.

The pharmacy in Switzerland Dr. Sikich planned to use couldn’t make enough for the study. Contracting with a compounding pharmacy in the United States was significantly more expensive and time consuming, but it was the researchers’ only option.

“If it hadn’t been something we expected to have a major benefit, I think we would have given up the project at multiple points along the line due to all of these challenges,” said Dr. Sikich.

In August 2014, with all the pieces finally in place, researchers began enrolling children aged 3-17 years. The final cohort included 290 participants with ASD, 146 in the oxytocin group and 144 in the placebo group. Of these, 48% had minimal verbal fluency, and 52% had fluent verbal speech.

Participants received daily synthetic oxytocin or placebo via a nasal spray for 24 weeks. The daily oxytocin dose was 48 IU for the first 7 weeks. After that, the dosage could be titrated to a maximum of 80 IU/d. The mean maximal total daily dose of oxytocin throughout the study was 67.6 ± 16.9 IU.
 

‘It just didn’t work’

Both study groups showed improvement in social withdrawal beginning at 4 weeks and continuing throughout the trial, as determined on the basis of caretakers’ responses on the Aberrant Behavior Checklist Modified Social Withdrawal Subscale, the study’s primary outcome measure.

Sociability and social motivation also improved in both groups, as measured by the Pervasive Developmental Disorders Behavior Inventory and the Social Responsiveness Scale.

But by the end of the trial, the difference between the groups in improvement of social function wasn’t significant (difference, -0.2 points; P = .61) after adjusting for age, verbal fluency, and baseline oxytocin level.

“We were so convinced that it would work,” Dr. Sikich said, “but it just didn’t.”

From observation, parents were also convinced the therapy was working. At the trial’s conclusion, fewer than half of caregivers correctly guessed whether their child was in the treatment group or the placebo group.

A lot of development changes can happen in a child over 6 months. It’s possible the improvements would have occurred regardless of the trial, Dr. Sikich said. Parents’ perceptions could also be a placebo effect. Their child was in a clinical trial of a drug they believed could improve social functioning, so in their mind, it did.

Caregivers received training in how to identify certain behavioral changes, which may have helped them spot an existing positive change they had previously overlooked. Or they may have worked with their child more intently as a result of their participation in the trial.

“People may start doing more things or doing them more intensively or purposefully, consciously or subconsciously, to try to help their child improve the skills or behaviors targeted by the active therapy in the study,” Dr. Sikich said. “These are things that might really help the child move forward which are completely separate from the medication being studied.”

The safety analysis offered more hopeful results. Only one serious adverse event from the treatment was reported: A 17-year-old participant taking a daily dose of 48 IU experienced a sedating effect while driving and had an accident.
 

Too soon to walk away?

Perhaps the most important take-away from the study is that even if it’s safe, intranasal oxytocin as it is currently used doesn’t work and clinicians shouldn’t prescribe it, said Daniel Geschwind, MD, PhD, director of the University of California, Los Angeles (UCLA) Center for Autism Research, who penned a commentary on the study and discussed the findings with this news organization.

“This study shows that using oxytocin the way it’s used in the community right now is not helping anybody, so why put a child through that?” added Dr. Geschwind, who also is a professor of genetics, neurology, and psychiatry at UCLA.

The trial highlights areas that need to be addressed in order to improve research in the field, he said. Establishing a consensus process to measure social functioning and figuring out a better way to access intranasal oxytocin would lead to studies that are more conclusive, comparable, and less expensive. Dr. Sikich agrees.

Despite the findings, Dr. Geschwind and other autism researchers say it’s too soon to walk away from oxytocin altogether, although it may be time to change the approach to autism research.

“We have to take a page from the playbook of modern medicine in other areas and begin to recognize that these syndromes are incredibly heterogeneous,” Dr. Geschwind says. “We can surmise, although we don’t know, that there might be different biological forms of autism that have different pathways involved that are going to respond differently to different medications.”

Calling the researchers’ efforts “heroic,” Karen Parker, PhD, an associate professor and associate chair of psychiatry and behavioral sciences at Stanford (Calif.) University, says efficacy trials such as this one are critical. However, Dr. Parker said in an interview, there are a number of questions that the study didn’t address.

The majority of medication dispensed in a standard intranasal device is sprayed into the back of the throat. Regular blood tests confirmed that oxytocin was getting into participants’ system, but, given how quickly oxytocin degrades in the blood, Dr. Parker said it’s hard to know just how much reached the brain.

It’s also unclear whether the results would have been different had the treatment been paired with behavioral therapy, an approach Dr. Parker suggests might benefit a subset of children with ASD.

A 2017 study from Dr. Parker’s lab found that children with ASD whose use of oxytocin at baseline was low derived greater benefit from synthetic oxytocin, something the new study failed to find. Still, Dr. Parker said, it’s possible oxytocin might increase social motivation and increase a child’s receptiveness to behavioral therapy.

“When you see a negative trial like this, it decreases enthusiasm for the therapy for autism in this context,” Dr. Parker said. “I hope people who are studying these syndromes will continue to explore oxytocin as a therapy.”

The study was funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development through the Autism Centers of Excellence Program and the Department of Psychiatry and Behavioral Sciences at Duke University.

The pharmacy in Switzerland Dr. Sikich planned to use couldn’t make enough for the study. Contracting with a compounding pharmacy in the United States was significantly more expensive and time consuming, but it was the researchers’ only option.

“If it hadn’t been something we expected to have a major benefit, I think we would have given up the project at multiple points along the line due to all of these challenges,” said Dr. Sikich.

In August 2014, with all the pieces finally in place, researchers began enrolling children aged 3-17 years. The final cohort included 290 participants with ASD, 146 in the oxytocin group and 144 in the placebo group. Of these, 48% had minimal verbal fluency, and 52% had fluent verbal speech.

Participants received daily synthetic oxytocin or placebo via a nasal spray for 24 weeks. The daily oxytocin dose was 48 IU for the first 7 weeks. After that, the dosage could be titrated to a maximum of 80 IU/d. The mean maximal total daily dose of oxytocin throughout the study was 67.6 ± 16.9 IU.
 

‘It just didn’t work’

Both study groups showed improvement in social withdrawal beginning at 4 weeks and continuing throughout the trial, as determined on the basis of caretakers’ responses on the Aberrant Behavior Checklist Modified Social Withdrawal Subscale, the study’s primary outcome measure.

Sociability and social motivation also improved in both groups, as measured by the Pervasive Developmental Disorders Behavior Inventory and the Social Responsiveness Scale.

But by the end of the trial, the difference between the groups in improvement of social function wasn’t significant (difference, -0.2 points; P = .61) after adjusting for age, verbal fluency, and baseline oxytocin level.

“We were so convinced that it would work,” Dr. Sikich said, “but it just didn’t.”

From observation, parents were also convinced the therapy was working. At the trial’s conclusion, fewer than half of caregivers correctly guessed whether their child was in the treatment group or the placebo group.

A lot of development changes can happen in a child over 6 months. It’s possible the improvements would have occurred regardless of the trial, Dr. Sikich said. Parents’ perceptions could also be a placebo effect. Their child was in a clinical trial of a drug they believed could improve social functioning, so in their mind, it did.

Caregivers received training in how to identify certain behavioral changes, which may have helped them spot an existing positive change they had previously overlooked. Or they may have worked with their child more intently as a result of their participation in the trial.

“People may start doing more things or doing them more intensively or purposefully, consciously or subconsciously, to try to help their child improve the skills or behaviors targeted by the active therapy in the study,” Dr. Sikich said. “These are things that might really help the child move forward which are completely separate from the medication being studied.”

The safety analysis offered more hopeful results. Only one serious adverse event from the treatment was reported: A 17-year-old participant taking a daily dose of 48 IU experienced a sedating effect while driving and had an accident.
 

Too soon to walk away?

Perhaps the most important take-away from the study is that even if it’s safe, intranasal oxytocin as it is currently used doesn’t work and clinicians shouldn’t prescribe it, said Daniel Geschwind, MD, PhD, director of the University of California, Los Angeles (UCLA) Center for Autism Research, who penned a commentary on the study and discussed the findings with this news organization.

“This study shows that using oxytocin the way it’s used in the community right now is not helping anybody, so why put a child through that?” added Dr. Geschwind, who also is a professor of genetics, neurology, and psychiatry at UCLA.

The trial highlights areas that need to be addressed in order to improve research in the field, he said. Establishing a consensus process to measure social functioning and figuring out a better way to access intranasal oxytocin would lead to studies that are more conclusive, comparable, and less expensive. Dr. Sikich agrees.

Despite the findings, Dr. Geschwind and other autism researchers say it’s too soon to walk away from oxytocin altogether, although it may be time to change the approach to autism research.

“We have to take a page from the playbook of modern medicine in other areas and begin to recognize that these syndromes are incredibly heterogeneous,” Dr. Geschwind says. “We can surmise, although we don’t know, that there might be different biological forms of autism that have different pathways involved that are going to respond differently to different medications.”

Calling the researchers’ efforts “heroic,” Karen Parker, PhD, an associate professor and associate chair of psychiatry and behavioral sciences at Stanford (Calif.) University, says efficacy trials such as this one are critical. However, Dr. Parker said in an interview, there are a number of questions that the study didn’t address.

The majority of medication dispensed in a standard intranasal device is sprayed into the back of the throat. Regular blood tests confirmed that oxytocin was getting into participants’ system, but, given how quickly oxytocin degrades in the blood, Dr. Parker said it’s hard to know just how much reached the brain.

It’s also unclear whether the results would have been different had the treatment been paired with behavioral therapy, an approach Dr. Parker suggests might benefit a subset of children with ASD.

A 2017 study from Dr. Parker’s lab found that children with ASD whose use of oxytocin at baseline was low derived greater benefit from synthetic oxytocin, something the new study failed to find. Still, Dr. Parker said, it’s possible oxytocin might increase social motivation and increase a child’s receptiveness to behavioral therapy.

“When you see a negative trial like this, it decreases enthusiasm for the therapy for autism in this context,” Dr. Parker said. “I hope people who are studying these syndromes will continue to explore oxytocin as a therapy.”

The study was funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development through the Autism Centers of Excellence Program and the Department of Psychiatry and Behavioral Sciences at Duke University.

On this occasion of writing our last of a decade of tech columns, we want to take the time to emphasize that our collective excitement about medical technology should never eclipse the reason for which it is created: to facilitate high-quality care.

Indeed, science and technology provide opportunities to improve outcomes in ways not even imagined 100 years ago, yet we must acknowledge that technology also threatens to erect barriers between us and our patients.

Threats to the physician-patient relationship

Medical history provides many examples of how our zeal to innovate can have untoward consequences to the physician-patient relationship.

In the late 1800s, for example, to convey a sense of science, purity of intent, and trust, the medical community began wearing white coats. Those white coats have been discussed as creating emotional distance between physicians and their patients.¹

Even when we in the medical community are slow and reluctant to change, the external forces propelling us forward often seem unstoppable; kinetic aspirations to innovate electronic information systems and new applications seem suddenly to revolutionize care delivery when we least expect it. The rapidity of change in technology can sometimes be dizzying but can at the same time can occur so swiftly we don’t even notice it.

After René Laennec invented the stethoscope in the early 1800s, clinicians no longer needed to physically lean in and place an ear directly onto patients to hear their hearts beating. This created a distance from patients that was still lamented 50 years later, when a professor of medicine is reported to have said, “he that hath ears to hear, let him use his ears and not a stethoscope.” Still, while the stethoscope has literally distanced us from patients, it is such an important tool that we no longer think about this distancing. We have adapted over time to remain close to our patients, to sincerely listen to their thoughts and reassure them that we hear them without the need to feel our ears on their chests.

Francis Peabody, the eminent Harvard physician, wrote an essay in 1927 titled, “The Care of the Patient.” At the end of the first paragraph, he states: “The most common criticism made at present by older practitioners is that young graduates ... are too “scientific” and do not know how to take care of patients.” He goes on to say that “one of the essential qualities of the clinician is interest in humanity, for the secret of the care of the patient is in caring for the patient.”²

We agree with Dr. Peabody. As we embrace science and technology that can change health outcomes, our patients’ needs to feel understood and cared for will not diminish. Instead, that need will continue to be an important aspect of our struggle and joy in providing holistic, humane, competent care into the future.

Twenty-first century physicians have access to an ever-growing trove of data, yet our ability to truly know our patients seems somehow less accessible. Home health devices have begun to provide a flow of information about parameters, ranging from continuous glucose readings to home blood pressures, weights, and inspiratory flow readings. These data can provide much more accurate insight into patients than what we can glean from one point in time during an office visit. Yet we need to remember that behind the data are people with dreams and desires, not just table entries in an electronic health record.

In 1923, the German philosopher Martin Buber published the book for which he is best known, “I and Thou.” In that book, Mr. Buber says that there are two ways we can approach relationships: “I-Thou” or “I-It.” In I-It relationships, we view the other person as an “it” to be used to accomplish a purpose, or to be experienced without his or her full involvement. In an I-Thou relationship, we appreciate the other people for all their complexity, in their full humanness. We must consciously remind ourselves amid the rush of technology that there are real people behind those data. We must acknowledge and approach each person as a unique individual who has dreams, goals, fears, and wishes that may be different from ours but to which we can still relate.

‘From the Beating End of the Stethoscope’

John Ciardi, an American poet, said the following in a poem titled, “Lines From the Beating End of the Stethoscope”:

I speak, as I say, the patient’s point of view.

But, given time, doctors are patients, too.

And there’s our bond: beyond anatomy,

Or in it, through it, to the mystery

Medicine takes the pulse of and lets go

Forever unexplained. It’s art, we know,

Not science at the heart. Doctor be whole,

I won’t insist the patient is a soul,

But he’s a something, possibly laughable,

Or possibly sublime, but not quite graphable.

Not quite containable on a bed chart.

Where science touches man it turns to art.³

This poem is a reminder of the subtle needs of patients during their encounters with doctors, especially around many of the most important decisions and events in their lives. Patients’ needs are varied, complex, difficult to discern, and not able to be fully explained or understood through math and science.

Einstein warned us that the modern age would be characterized by a perfection of means and a confusion of goals.⁴ As clinicians, we should strive to clarify and align our goals with those of our patients, providing care that is real, compassionate, and personal, not just an optimized means to achieve standardized metrics. While technology can assist us in this pursuit, we’ll need be careful that our enchantment with innovation does not cloud our actual goal: truly caring for our patients.

A new survey of U.S. patients with breast cancer found that 42% were using cannabis, primarily to relieve side effects associated with treatment, such as pain, anxiety, nausea, and insomnia.

Most (75%) of the patients who reported using cannabis said it was extremely helpful or very helpful in alleviating symptoms.

The authors warn of potential safety concerns with cannabis, especially with the use of unregulated products.

In addition, the survey found that physicians were not highly regarded as a source of information about cannabis use. Only 39% of patients said that they discussed cannabis with their physicians; 28% reported feeling uncomfortable when broaching the topic. Only 4% indicated that physicians were the most helpful source of information about cannabis.

The survey involved 612 patients with breast cancer. The results were published online Oct. 12 in Cancer.

“Our study highlights an important opportunity for providers to initiate informed conversations about medical cannabis with their patients, as the evidence shows that many are using medical cannabis without our knowledge or guidance,” said lead author Marisa Weiss, MD, of Breastcancer.org and the Lankenau Medical Center, near Philadelphia. “Not knowing whether or not our cancer patients are using cannabis is a major blind spot in our ability to provide optimal care,” she said.

Cannabis in one form or another has been legalized in many states across America, and even in states where it hasn’t been legalized, people are using it.

“Even though many states have relaxed their laws on cannabis, it remains a Schedule I drug on the federal level and is essentially still considered illegal,” commented Donald I. Abrams, MD, professor of medicine at the University of California, San Francisco, and an integrative oncologist at the UCSF Osher Center for Integrative Medicine. “This is why many physicians are uncomfortable discussing it with patients,” he said.

“Cannabis use isn’t taught in medical school, and until that changes, I don’t know how physicians are going to be advisers for this,” said Dr. Abrams, who was approached by this news organization for comment.

This “is a really nice study in that it looks at a large group of breast cancer patients from the community ... It’s not from a single institution [such as this previous study] and so a more representative mix,” Dr. Abrams said.

However, he also commented that the article had a “scent of ‘reefer madness’” about it, given its emphasis on potential harms and safety concerns.

“It’s interesting how alcohol is considered mainstream but cannabis has been demonized,” he said. “Especially for women with breast cancer, it’s so clear that alcohol is related to the development of postmenopausal breast cancer. As a recreational intervention, cannabis in my mind appears to be much safer for women for relaxation.”

“The one thing I worry about are patients who take highly concentrated CBD [cannabidiol] oil, as it can block the metabolism of prescription drugs and allow them to build up in the blood,” Dr. Abrams said. “I advise people against using these products.”
 

Cannabis to relieve symptoms

Previous studies have noted widespread use of cannabis among patients with cancer. For example, a large study from Israel that included nearly 3,000 participants found that cannabis use improved a variety of cancer-related symptoms, including nausea and vomiting, sleep disorders, pain, anxiety, and depression. Among those with cancer who survived to 6 months and who finished the study protocol, 60% achieved “treatment success.” Of note, at 6 months, 36% of patients had stopped taking opioids, and for 9.9%, the dose of opioids had decreased.

In the current study, dubbed the Coala-T-Cannabis study, the investigators approached U.S. members of the Breastcancer.org and Healthline.com communities who self-reported that they had been diagnosed with breast cancer within the past 5 years; 612 surveys were completed.

Half of all respondents said they had looked for information on medical cannabis, but most were unsatisfied with the information that they had received. Only 6% were extremely satisfied; 25% were very satisfied with the information.

Most patients (39%) did not discuss cannabis use with their physicians. Of those who did, 28% reported feeling uncomfortable discussing the topic. Only 4% of survey respondents indicated that physicians were the most helpful source of cannabis information.

Regarding which source of information was most helpful, 22% said websites, 18% said family members or friends, 12% said staffers and pharmacists in dispensaries, and 7% said other patients with breast cancer.

Forty-two percent of the survey respondents said they used cannabis for medical purposes and for relief of symptoms, which included pain (78%), insomnia (70%), anxiety (57%), stress (51%), and nausea/vomiting (46%).

In addition, 49% believed that medical cannabis could be used to treat the cancer itself.

A fair number were also using cannabis for recreational purposes. Of those who used cannabis, only 23% reported that they used it for medical purposes only.

Participants used cannabis in a variety of forms. The most popular form of consumption was as edibles (70%), followed by liquids/tinctures (65%), smoking (51%), topicals (46%), and vape pens (45%). Participants reported using an average of 3.7 different products.
 

Safety concerns?

The authors caution about the use of cannabis while receiving anticancer therapies because such use “raises important efficacy and safety concerns.”

“Many chemotherapy agents as well as cannabinoids are metabolized in the liver’s p450 cytochrome system,” Dr. Weiss and colleagues note, and the mechanism by which cannabinoids interact with particular CYP450 isoenzymes “has the potential to alter the metabolism of other medications and lead to adverse side effects.”

They also question the safety of some of the cannabis products that are being used. Participants reported receiving cannabis from a variety of sources, which included state-regulated dispensaries, “dealers,” and family/friends.

Three-quarters of respondents believed that cannabis was better than “chemicals” and that the benefits outweighed the risks. But many of the products used are unregulated, the authors point out.

“Providers should communicate clearly about the health and safety concerns associated with certain cannabis products and methods of delivery,” they conclude. “Without these measures, patients may make these decisions without qualified medical guidance, obtain poor-quality cannabis products, and consume them through potentially hazardous delivery methods during various types of cancer therapies.”

The study was supported by research grants from Ananda Health/Ecofibre and the Dr. Philip Reeves Legacy Fund. Several coauthors reported relationships with industry, as noted in the article. Dr. Abrams owns stock in Cannformatics and Lumen; he has received honorarium from Clever Leaves and Maui Grown Therapies and speaker honorarium from GW Pharmaceuticals.

However, he also commented that the article had a “scent of ‘reefer madness’” about it, given its emphasis on potential harms and safety concerns.

“It’s interesting how alcohol is considered mainstream but cannabis has been demonized,” he said. “Especially for women with breast cancer, it’s so clear that alcohol is related to the development of postmenopausal breast cancer. As a recreational intervention, cannabis in my mind appears to be much safer for women for relaxation.”

“The one thing I worry about are patients who take highly concentrated CBD [cannabidiol] oil, as it can block the metabolism of prescription drugs and allow them to build up in the blood,” Dr. Abrams said. “I advise people against using these products.”
 

Cannabis to relieve symptoms

Previous studies have noted widespread use of cannabis among patients with cancer. For example, a large study from Israel that included nearly 3,000 participants found that cannabis use improved a variety of cancer-related symptoms, including nausea and vomiting, sleep disorders, pain, anxiety, and depression. Among those with cancer who survived to 6 months and who finished the study protocol, 60% achieved “treatment success.” Of note, at 6 months, 36% of patients had stopped taking opioids, and for 9.9%, the dose of opioids had decreased.

In the current study, dubbed the Coala-T-Cannabis study, the investigators approached U.S. members of the Breastcancer.org and Healthline.com communities who self-reported that they had been diagnosed with breast cancer within the past 5 years; 612 surveys were completed.

Half of all respondents said they had looked for information on medical cannabis, but most were unsatisfied with the information that they had received. Only 6% were extremely satisfied; 25% were very satisfied with the information.

Most patients (39%) did not discuss cannabis use with their physicians. Of those who did, 28% reported feeling uncomfortable discussing the topic. Only 4% of survey respondents indicated that physicians were the most helpful source of cannabis information.

Regarding which source of information was most helpful, 22% said websites, 18% said family members or friends, 12% said staffers and pharmacists in dispensaries, and 7% said other patients with breast cancer.

Forty-two percent of the survey respondents said they used cannabis for medical purposes and for relief of symptoms, which included pain (78%), insomnia (70%), anxiety (57%), stress (51%), and nausea/vomiting (46%).

In addition, 49% believed that medical cannabis could be used to treat the cancer itself.

A fair number were also using cannabis for recreational purposes. Of those who used cannabis, only 23% reported that they used it for medical purposes only.

Participants used cannabis in a variety of forms. The most popular form of consumption was as edibles (70%), followed by liquids/tinctures (65%), smoking (51%), topicals (46%), and vape pens (45%). Participants reported using an average of 3.7 different products.
 

Safety concerns?

The authors caution about the use of cannabis while receiving anticancer therapies because such use “raises important efficacy and safety concerns.”

“Many chemotherapy agents as well as cannabinoids are metabolized in the liver’s p450 cytochrome system,” Dr. Weiss and colleagues note, and the mechanism by which cannabinoids interact with particular CYP450 isoenzymes “has the potential to alter the metabolism of other medications and lead to adverse side effects.”

They also question the safety of some of the cannabis products that are being used. Participants reported receiving cannabis from a variety of sources, which included state-regulated dispensaries, “dealers,” and family/friends.

Three-quarters of respondents believed that cannabis was better than “chemicals” and that the benefits outweighed the risks. But many of the products used are unregulated, the authors point out.

“Providers should communicate clearly about the health and safety concerns associated with certain cannabis products and methods of delivery,” they conclude. “Without these measures, patients may make these decisions without qualified medical guidance, obtain poor-quality cannabis products, and consume them through potentially hazardous delivery methods during various types of cancer therapies.”

The study was supported by research grants from Ananda Health/Ecofibre and the Dr. Philip Reeves Legacy Fund. Several coauthors reported relationships with industry, as noted in the article.

A new survey of U.S. patients with breast cancer found that 42% were using cannabis, primarily to relieve side effects associated with treatment, such as pain, anxiety, nausea, and insomnia.

Most (75%) of the patients who reported using cannabis said it was extremely helpful or very helpful in alleviating symptoms.

The authors warn of potential safety concerns with cannabis, especially with the use of unregulated products.

In addition, the survey found that physicians were not highly regarded as a source of information about cannabis use. Only 39% of patients said that they discussed cannabis with their physicians; 28% reported feeling uncomfortable when broaching the topic. Only 4% indicated that physicians were the most helpful source of information about cannabis.

The survey involved 612 patients with breast cancer. The results were published online Oct. 12 in Cancer.

“Our study highlights an important opportunity for providers to initiate informed conversations about medical cannabis with their patients, as the evidence shows that many are using medical cannabis without our knowledge or guidance,” said lead author Marisa Weiss, MD, of Breastcancer.org and the Lankenau Medical Center, near Philadelphia. “Not knowing whether or not our cancer patients are using cannabis is a major blind spot in our ability to provide optimal care,” she said.

Cannabis in one form or another has been legalized in many states across America, and even in states where it hasn’t been legalized, people are using it.

“Even though many states have relaxed their laws on cannabis, it remains a Schedule I drug on the federal level and is essentially still considered illegal,” commented Donald I. Abrams, MD, professor of medicine at the University of California, San Francisco, and an integrative oncologist at the UCSF Osher Center for Integrative Medicine. “This is why many physicians are uncomfortable discussing it with patients,” he said.

“Cannabis use isn’t taught in medical school, and until that changes, I don’t know how physicians are going to be advisers for this,” said Dr. Abrams, who was approached by this news organization for comment.

Mothers who use cannabis during pregnancy risk disrupting immune gene networks in the placenta and potentially increasing the risk of anxiety and hyperactivity in their children.

These findings emerged from a study led by Yasmin Hurd, PhD, a professor of psychiatry and director of the Addiction Institute at the Icahn School of Medicine at Mount Sinai, New York, and Yoko Nomura, PhD, a professor of behavioral neuroscience at Queen’s College, City University of New York, that was published online in Proceedings of the National Academy of Sciences.

The analysis assessed the effects of gestational maternal cannabis use on psychosocial and physiological measures in young children as well as its potentially immunomodulatory effect on the in utero environment as reflected in the placental transcriptome.

Participants were drawn from a larger cohort in a study launched in 2012; the investigators evaluated offspring aged 3-6 years for hair hormone levels, neurobehavioral traits on the Behavioral Assessment System for Children survey, and heart rate variability (HRV) at rest and during auditory startle.

The cohort consisted of 322 mother-child dyads and children with prenatal exposure to cannabis were compared with those having no exposure. The cohort consisted of 251 non–cannabis-using mothers and 71 cannabis-using mothers, with mean maternal ages in the two groups of 28.46 years and 25.91 years, respectively, The mothers gave birth at Mount Sinai and they and their children were assessed annually at affiliated medical centers in Mount Sinai’s catchment area.

For a subset of children with behavioral assessments, placental specimens collected at birth were processed for RNA sequencing.

Among the findings:

• Maternal cannabis use was associated with reduced maternal and paternal age, more single-mother pregnancies, state anxiety, trait anxiety, depression, cigarette smoking, and African American race.
• Hair hormone analysis revealed increased cortisol levels in the children of cannabis-using mothers, and was associated with greater anxiety, aggression, and hyperactivity.
• Affected children showed a reduction in the high-frequency component of HRV at baseline, reflecting reduced vagal tone.
• In the placenta, there was reduced expression of many genes involved in immune system function. These included genes for type I interferon, neutrophil, and cytokine-signaling pathways.

Several of these genes organized into coexpression networks that correlated with child anxiety and hyperactivity.

The principal active component of cannabis, tetrahydrocannabinol (THC), targets the endocannabinoid system in placental tissue and the developing brain, the authors noted. Exposure during pregnancy is associated with a range of adverse outcomes from fetal growth restriction to low birth weight and preterm birth.

“There are cannabinoid receptors on immune cells, and it is known that cannabinoids can alter immune function, which is important for maintaining maternal tolerance and protecting the fetus,” Dr. Hurd said. “It’s not surprising that something that affects the immune cells can have an impact on the developing fetus.”

“Overall, our findings reveal a relationship between [maternal cannabis use] and immune response gene networks in the placenta as a potential mediator of risk for anxiety-related problems in early childhood,” Dr. Hurd and colleagues wrote, adding that the results have significant implications for defining mental health issues in the children gestated by cannabis-smoking mothers.

Their results align with previous research indicating a greater risk for psychiatric illness in children with prenatal cannabis exposure from maternal use.

“While data are pretty limited in this realm, there are other studies that demonstrate a relationship between early child developmental and behavioral measures and cannabis use during pregnancy,” Camille Hoffman, MD, MSc, a high-risk obstetrics specialist and an associate professor at the University of Colorado at Denver, Aurora, said in an interview. “Our research group found children exposed to cannabis in utero at 10 weeks’ gestation and beyond were less interactive and more withdrawn than children who were not exposed.”

And THC remains in maternal breast milk even 6 weeks after usage stops.

The long-term effects of prenatal cannabis exposure remain to be determined and it is unknown whether the effects of gestational THC might attenuate as a child grows older. “We use early childhood measures in research as a proxy for the later development of diagnosed mental health conditions or behavioral problems,” Dr. Hoffman explained. “We know when we do this that not every child with an abnormal score early will go on to develop an actual condition. Fortunately, or unfortunately, other factors and exposures during childhood can change the trajectory for the better or worse.”

According to Dr. Hurd, child development is a dynamic process and epigenetic events in utero need not be deterministic. “The important thing is to identify children at risk early and to be able to go in and try to improve the environment they’re being raised in – not in terms of impoverishment but in terms of positive nurturing and giving the mother and family support.”

At the prenatal level, what’s the best advice for cannabis-using mothers-to-be? “If a woman doesn’t know she’s pregnant and has been using cannabis, taking extra choline for the remainder of the pregnancy can help buffer the potential negative impact of the cannabis exposure,” Dr. Hoffman said. The Food and Drug Administration and the American Medical Association recommend a dose of 550 mg daily. “The same is true for alcohol, which we know is also very bad for fetal brain development. This is not to say go ahead and use these substances and just take choline. The choline is more to try and salvage damage to the fetal brain that may have already occurred.”

This study was supported by the National Institute of Mental Health and the National Institute on Drug Abuse. The authors declared no competing interests. Dr. Hoffman disclosed no conflicts of interest with respect to her comments.

At its November meeting, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) voted against Biogen’s controversial Alzheimer’s drug aducanumab (Aduhelm), making it highly unlikely the drug will be recommended for approval at its December meeting.

In a news release issued Nov. 17, Biogen said the company received a “negative trend vote” on the aducanumab marketing authorization application in Europe.

“While we are disappointed with the trend vote, we strongly believe in the strength of our data and that aducanumab has the potential to make a positive and meaningful difference for people and families affected by Alzheimer’s disease [AD],” Priya Singhal, MD, MPH, head of global safety and regulatory sciences and interim head of research and development at Biogen, said in the release.

The EMA committee is expected to adopt a formal opinion on the marketing application at its December meeting (Dec. 13-16, 2021).

“Biogen will continue to engage with the EMA and CHMP as it considers next steps towards the goal of providing access to aducanumab to patients in Europe,” the company said.

At the recent Clinical Trials on Alzheimer’s Disease conference, Biogen announced new phase 3 findings that “provide further evidence of aducanumab’s effect on lowering amyloid beta plaque and downstream tau pathology, the two defining pathologies of Alzheimer’s disease,” the company said.
 

No clinically meaningful effect

In a statement from the nonprofit U.K. Science Media Centre, Prof. Robert Howard, from University College London, said the result of the CHMP vote “is absolutely the decision that we should have expected from the EMA’s expert advisory panel and is consistent with the FDA’s [U.S. Food and Drug Administration’s] Advisory Committee who voted unanimously 12 months ago against approval of aducanumab because of a lack of demonstrable efficacy in the pivotal phase 3 trials ENGAGE and EMERGE.”

“The FDA’s accelerated approval of aducanumab, solely on the grounds that it was reasonable to expect that reduction in amyloid would lead to improvement in the course of Alzheimer’s disease, despite all the evidence indicating no meaningful correlation between amyloid reduction and symptom improvement, has been highly controversial and has called into question the impartiality of the FDA and its staff,” Prof. Howard noted.

He anticipates that when the EMA panel meets in December they will not grant a license to aducanumab.

“Aducanumab is a treatment without convincing efficacy, with serious associated adverse effects and a high financial cost. On the basis of the available evidence and in the best interests of people with Alzheimer’s disease, their families and those who care for them, EMA and MHRA [Medicines and Healthcare products Regulatory Agency] should not approve a license for aducanumab,” Prof. Howard said.

Also weighing in, David Thomas, head of policy at Alzheimer’s Research UK, said the need for new AD treatments is “urgent,” but added that “it’s vital that regulators judge that any new treatment is safe and effective.”

“Results of aducanumab’s phase 3 trials, EMERGE and ENGAGE, have sparked much debate among the research community about how to judge the effectiveness of any new Alzheimer’s treatment,” Mr. Thomas noted.

“The FDA’s approval of aducanumab in the U.S. was based on the drug’s ability to clear the hallmark Alzheimer’s protein amyloid from the brain. As part of this approval the regulator now requires further trials to be carried out to ensure that aducanumab brings long-term improvement to people’s memory, thinking and day-to-day lives,” Mr. Thomas said.

EMA is now undertaking its own review of the data and “it’s important that we wait for the committee’s official recommendation, which is expected next month. In the meantime, we must continue to work at pace to ensure researchers are developing a broad pipeline of potential new treatments for diseases like Alzheimer’s, and that health systems like the NHS [National Health Service] will be ready to deliver them in the years ahead,” he added.
 

‘Reckless’ FDA decision

In related news, the Centers for Medicare and Medicaid Services (CMS) has announced that the Medicare Part B standard premium would rise to $170 per month for all enrollees, a 15% spike over the 2021 premium level.

“All Part B Medicare beneficiaries soon will be forced to bear significant financial burden as a direct result of the FDA’s reckless decision to approve aducanumab, a drug that has not been proven to provide any clinically meaningful benefit to Alzheimer’s patients but nevertheless carries an indefensible annual price tag set by Biogen at $56,000 per year for just the drug alone,” Michael Carome, MD, director of Public Citizen’s Health Research Group, said in a statement.

“To protect the many Medicare beneficiaries who cannot afford the unacceptable 15% jump in Part B premiums, CMS must promptly announce that it will exclude aducanumab from coverage under the Medicare program until there is definitive evidence that the drug provides substantial evidence of cognitive benefit to Alzheimer’s disease patients,” Dr. Carome said.

“The FDA’s approval of aducanumab in the U.S. was based on the drug’s ability to clear the hallmark Alzheimer’s protein amyloid from the brain. As part of this approval the regulator now requires further trials to be carried out to ensure that aducanumab brings long-term improvement to people’s memory, thinking and day-to-day lives,” Mr. Thomas said.

EMA is now undertaking its own review of the data and “it’s important that we wait for the committee’s official recommendation, which is expected next month. In the meantime, we must continue to work at pace to ensure researchers are developing a broad pipeline of potential new treatments for diseases like Alzheimer’s, and that health systems like the NHS [National Health Service] will be ready to deliver them in the years ahead,” he added.
 

‘Reckless’ FDA decision

In related news, the Centers for Medicare and Medicaid Services (CMS) has announced that the Medicare Part B standard premium would rise to $170 per month for all enrollees, a 15% spike over the 2021 premium level.

“All Part B Medicare beneficiaries soon will be forced to bear significant financial burden as a direct result of the FDA’s reckless decision to approve aducanumab, a drug that has not been proven to provide any clinically meaningful benefit to Alzheimer’s patients but nevertheless carries an indefensible annual price tag set by Biogen at $56,000 per year for just the drug alone,” Michael Carome, MD, director of Public Citizen’s Health Research Group, said in a statement.

“To protect the many Medicare beneficiaries who cannot afford the unacceptable 15% jump in Part B premiums, CMS must promptly announce that it will exclude aducanumab from coverage under the Medicare program until there is definitive evidence that the drug provides substantial evidence of cognitive benefit to Alzheimer’s disease patients,” Dr. Carome said.

At its November meeting, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) voted against Biogen’s controversial Alzheimer’s drug aducanumab (Aduhelm), making it highly unlikely the drug will be recommended for approval at its December meeting.

In a news release issued Nov. 17, Biogen said the company received a “negative trend vote” on the aducanumab marketing authorization application in Europe.

“While we are disappointed with the trend vote, we strongly believe in the strength of our data and that aducanumab has the potential to make a positive and meaningful difference for people and families affected by Alzheimer’s disease [AD],” Priya Singhal, MD, MPH, head of global safety and regulatory sciences and interim head of research and development at Biogen, said in the release.

The EMA committee is expected to adopt a formal opinion on the marketing application at its December meeting (Dec. 13-16, 2021).

“Biogen will continue to engage with the EMA and CHMP as it considers next steps towards the goal of providing access to aducanumab to patients in Europe,” the company said.

At the recent Clinical Trials on Alzheimer’s Disease conference, Biogen announced new phase 3 findings that “provide further evidence of aducanumab’s effect on lowering amyloid beta plaque and downstream tau pathology, the two defining pathologies of Alzheimer’s disease,” the company said.
 

No clinically meaningful effect

In a statement from the nonprofit U.K. Science Media Centre, Prof. Robert Howard, from University College London, said the result of the CHMP vote “is absolutely the decision that we should have expected from the EMA’s expert advisory panel and is consistent with the FDA’s [U.S. Food and Drug Administration’s] Advisory Committee who voted unanimously 12 months ago against approval of aducanumab because of a lack of demonstrable efficacy in the pivotal phase 3 trials ENGAGE and EMERGE.”

“The FDA’s accelerated approval of aducanumab, solely on the grounds that it was reasonable to expect that reduction in amyloid would lead to improvement in the course of Alzheimer’s disease, despite all the evidence indicating no meaningful correlation between amyloid reduction and symptom improvement, has been highly controversial and has called into question the impartiality of the FDA and its staff,” Prof. Howard noted.

He anticipates that when the EMA panel meets in December they will not grant a license to aducanumab.

“Aducanumab is a treatment without convincing efficacy, with serious associated adverse effects and a high financial cost. On the basis of the available evidence and in the best interests of people with Alzheimer’s disease, their families and those who care for them, EMA and MHRA [Medicines and Healthcare products Regulatory Agency] should not approve a license for aducanumab,” Prof. Howard said.

Also weighing in, David Thomas, head of policy at Alzheimer’s Research UK, said the need for new AD treatments is “urgent,” but added that “it’s vital that regulators judge that any new treatment is safe and effective.”

The Centers for Disease Control and Prevention reported that an estimated 100,306 Americans died from drug overdoses during the period from April 2020 to April 2021, a 28.5% increase from the previous year.

Deaths in some states rose even more precipitously. Vermont saw an almost 70% increase, and drug overdose deaths in West Virginia increased by 62%. Many states, including Alabama, California, Kansas, Kentucky, Louisiana, Tennessee, and Washington, had a 45%-50% rise in overdose deaths.

The data released by the CDC was provisional, as there is generally a lag between a reported overdose and confirmation of the death to the National Vital Statistics System. The agency uses statistical models that render the counts almost 100% accurate, the CDC says.

The vast majority (73,757) of overdose deaths involved opioids – with most of those (62,338) involving synthetic opioids such as fentanyl. Federal officials said that one American died every 5 minutes from an overdose, or 265 a day.

“We have to acknowledge what this is – it is a crisis,” Department of Health & Human Services Secretary Xavier Becerra told reporters on a call.

“As much as the numbers speak so vividly, they don’t tell the whole story. We see it in the faces of grieving families and all those overworked caregivers. You hear it every time you get that panicked 911 phone call, you read it in obituaries of sons and daughters who left us way too soon,” Mr. Becerra said.

Rahul Gupta, MD, director of the White House Office of National Drug Control Policy, said that “this is unacceptable, and it requires an unprecedented response.”

Dr. Gupta, who noted that he has a waiver to treat substance use disorder patients with buprenorphine, said he’s seen “first-hand the heartbreak of the overdose epidemic,” adding that, with 23 years in practice, “I’ve learned that an overdose is a cry for help and for far too many people that cry goes unanswered.”

Both Mr. Becerra and Dr. Gupta called on Congress to pass President Joe Biden’s fiscal 2022 budget request, noting that it calls for $41 billion – a $669 million increase from fiscal year 2021 – to go to agencies working on drug interdiction and substance use prevention, treatment, and recovery support. 

Dr. Gupta also announced that the administration was releasing a model law that could be used by state legislatures to help standardize policies on making the overdose antidote naloxone more accessible. Currently, such policies are a patchwork across the nation.

In addition, the federal government is newly supporting harm reduction, Mr. Becerra said. This means federal money can be used by clinics and outreach programs to buy fentanyl test strips, which they can then distribute to drug users.

“It’s important for Americans to have the ability to make sure that they can test for fentanyl in the substance,” Dr. Gupta said.
 

Fake pills, fentanyl a huge issue

Federal officials said that both fentanyl and methamphetamine are contributing to rising numbers of fatalities.

“Drug cartels in Mexico are mass-producing fentanyl and methamphetamine largely sourced from chemicals in China and they are distributing these substances throughout the United States,” Anne Milgram, administrator of the Drug Enforcement Administration, said on the call.

Ms. Milgram said the agency had seized 12,000 pounds of fentanyl in 2021, enough to provide every American with a lethal dose. Fentanyl is also mixed in with cocaine, heroin, methamphetamine, and marijuana – often in counterfeit pills, Ms. Milgram said.

The DEA and other law enforcement agencies have seized more than 14 million such pills in 2021. “These types of pills are easily accessible today on social media and e-commerce platforms, Ms. Milgram said.

“Drug dealers are now in our homes,” she said. “Wherever there is a smart phone or a computer, a dealer is one click away,” Ms. Milgram said.

National Institute on Drug Abuse Director Nora D. Volkow, MD, said that dealers will continue to push both fentanyl and methamphetamine because they are among the most addictive substances. They also are more profitable because they don’t require cultivation and harvesting, she said on the call.

Dr. Volkow also noted that naloxone is not as effective in reversing fentanyl overdoses because fentanyl is more potent than heroin and other opioids, and “it gets into the brain extremely rapidly.”

Ongoing research is aimed at developing a faster delivery mechanism and a longer-lasting formulation to counter overdoses, Dr. Volkow said.

Deer, COVID, how?

Usually humans cannot get close enough to a deer to really be face-to-face, so it’s easy to question how on Earth deer are contracting COVID-19. Well, stranger things have happened, and honestly, we’ve just stopped questioning most of them.

petemeade/PxHere

Exhibit A comes to us from a Penn State University study: Eighty percent of deer sampled in Iowa in December 2020 and January 2021 – as part of the state’s chronic wasting disease surveillance program – were found to be positive for COVID-19.

A statement from the university said that “white-tailed deer may be a reservoir for the virus to continually circulate and raise concerns about the emergence of new strains that may prove a threat to wildlife and, possibly, to humans.” The investigators also suggested that deer probably caught the virus from humans and then transmitted it to other deer.

If you or someone you know is a hunter or a white-tailed deer, it’s best to proceed with caution. There’s no evidence that COVID-19 has jumped from deer to humans, but hunters should wear masks and gloves while working with deer, worrying not just about the deer’s face, but also … you know, the gastrointestinal parts, Robert Salata, MD, of University Hospitals Cleveland Medical Center, told Syracuse.com. It also shouldn’t be too risky to eat venison, he said, just make sure the meat is cooked thoroughly.

The neurological super powers of grandma are real

What is it about grandmothers that makes them seem almost magical at times? They somehow always know how you feel. And they can almost always tell when something is wrong. They also seem to be the biggest ally a child will have against his or her parents.

Mark Edward Atkinson/Tracey Lee

So what makes these super matriarchs? The answer is in the brain.

Apparently there’s a function in the brains of grandmothers geared toward “emotional empathy.” James Rilling, PhD, of Emory University, lead author of a recent study focused on looking at the brain function of grandmothers, suggested that they’re neurologically tapped into feeling how their grandchildren feel: “If their grandchild is smiling, they’re feeling the child’s joy. And if their grandchild is crying, they’re feeling the child’s pain and distress.”

And then there’s the cute factor. Never underestimate a child’s ability to manipulate his or her grandmother’s brain.

So how do the researchers know this? Functional MRI showed more brain activity in the parts of the brain that deal with emotional empathy and movement in the participating grandmas when shown pictures of their grandchildren. Images of their own adult children lit up areas more associated with cognitive empathy. So less emotional and more mental/logical understanding.

Kids, don’t tell Mom about the secret midnight snacks with grandma. She wouldn’t get it.

Then there’s the grandmother hypothesis, which suggests that women tend to live longer to provide some kind of evolutionary benefit to their children and grandchildren. Evidence also exists that children with positive engagement from their grandmothers tend to have better social and academic outcomes, behavior, and physical health.

A lot of credit on how children turn out, of course, goes to parents, but more can be said about grandmas. Don’t let the age and freshly baked cookies fool you. They have neurologic superpowers within.
 

Brain cleanup on aisle 5

You’ve got your local grocery store down. You know the ins and outs; you know where everything is. Last week you did your trip in record time. This week, however, you have to stop at a different store. Same chain, but a different location. You stroll in, confidently walk toward the first aisle for your fruits and veggies, and ... it’s all ice cream. Oops.

Max Pixel

There’s a lot we don’t understand about the brain, including how it remembers familiar environments to avoid confusion. Or why it fails to do so, as with our grocery store example. However, thanks to a study from the University of Arizona, we may have an answer.

For the experiment, a group of participants watched a video tour of three virtual cities. Those cities were very similar, being laid out in basically identical fashion. Stores could be found in the same places, but the identity of those stores varied. Some stores were in all three cities, some were in two, and some were unique. Participants were asked to memorize the layouts, and those who got things more than 80% correct ran through the test again, only this time their brain activity was monitored through MRI.

In general, brain activity was similar for the participants; after all, they were recalling similar environments. However, when asked about stores that appeared in multiple cities, brain activity varied dramatically. This indicated to the researchers that the brain was recalling shared stores as if they were more dissimilar than two completely disparate and unique stores, a concept often known to brain scientists as “repulsion.” It also indicates that the memories regarding shared environments are stored in the prefrontal cortex, not the hippocampus, which typically handles memory.

The researchers plan to apply this information to questions about diseases such as Alzheimer’s, so the next time you get turned around in a weirdly unfamiliar grocery store, just think: “It’s okay, I’m helping to solve a terrible brain disease.”
 

The real endgame: Friction is the winner

Spoiler alert! If you haven’t seen “Avengers: Infinity War” yet, we’re about to ruin it for you.

Georgia Tech

For those still with us, here’s the spoiler: Thanos would not have been able to snap his fingers while wearing the Infinity Gauntlet.

Saad Bhamla, PhD, of Georgia Tech University’s school of chemical and biomolecular engineering, had been studying powerful and ultrafast motions in living organisms along with several colleagues before the movie came out in 2018, and when they saw the finger-snapping scene it got them wondering.

Being scientists of course, they had no choice. They got out their high-speed imaging equipment, automated image processing software, and dynamic force sensors and analyzed finger snaps, paying close attention to friction by covering fingers with “different materials, including metallic thimbles to simulate the effects of trying to snap while wearing a metallic gauntlet, much like Thanos,” according to a statement on Eurekalert.

With finger snaps, it’s all about the rotational velocity. The angular acceleration involved is the fastest ever measured in a human, with a professional baseball pitcher’s throwing arm a distant second.

Dr. Bhamla’s reaction to their work explains why scientists are the ones doing science. “When I first saw the data, I jumped out of my chair,” he said in the written statement.

Rotational velocities dropped dramatically when the friction-reducing thimbles were used, so there was no snap. Which means that billions and billions of fictional lives could have been saved if the filmmakers had just talked to the right scientist.

That scientist, clearly, is Dr. Bhamla, who said that “this is the only scientific project in my lab in which we could snap our fingers and get data.”

There’s no evidence that COVID-19 has jumped from deer to humans, but hunters should wear masks and gloves while working with deer, worrying not just about the deer’s face, but also … you know, the gastrointestinal parts, Robert Salata, MD, of University Hospitals Cleveland Medical Center, told Syracuse.com. It also shouldn’t be too risky to eat venison, he said, just make sure the meat is cooked thoroughly.

The neurological super powers of grandma are real

What is it about grandmothers that makes them seem almost magical at times? They somehow always know how you feel. And they can almost always tell when something is wrong. They also seem to be the biggest ally a child will have against his or her parents.

Mark Edward Atkinson/Tracey Lee

So what makes these super matriarchs? The answer is in the brain.

Apparently there’s a function in the brains of grandmothers geared toward “emotional empathy.” James Rilling, PhD, of Emory University, lead author of a recent study focused on looking at the brain function of grandmothers, suggested that they’re neurologically tapped into feeling how their grandchildren feel: “If their grandchild is smiling, they’re feeling the child’s joy. And if their grandchild is crying, they’re feeling the child’s pain and distress.”

And then there’s the cute factor. Never underestimate a child’s ability to manipulate his or her grandmother’s brain.

So how do the researchers know this? Functional MRI showed more brain activity in the parts of the brain that deal with emotional empathy and movement in the participating grandmas when shown pictures of their grandchildren. Images of their own adult children lit up areas more associated with cognitive empathy. So less emotional and more mental/logical understanding.

Kids, don’t tell Mom about the secret midnight snacks with grandma. She wouldn’t get it.

Then there’s the grandmother hypothesis, which suggests that women tend to live longer to provide some kind of evolutionary benefit to their children and grandchildren. Evidence also exists that children with positive engagement from their grandmothers tend to have better social and academic outcomes, behavior, and physical health.

A lot of credit on how children turn out, of course, goes to parents, but more can be said about grandmas. Don’t let the age and freshly baked cookies fool you. They have neurologic superpowers within.
 

Brain cleanup on aisle 5

You’ve got your local grocery store down. You know the ins and outs; you know where everything is. Last week you did your trip in record time. This week, however, you have to stop at a different store. Same chain, but a different location. You stroll in, confidently walk toward the first aisle for your fruits and veggies, and ... it’s all ice cream. Oops.

Max Pixel

There’s a lot we don’t understand about the brain, including how it remembers familiar environments to avoid confusion. Or why it fails to do so, as with our grocery store example. However, thanks to a study from the University of Arizona, we may have an answer.

For the experiment, a group of participants watched a video tour of three virtual cities. Those cities were very similar, being laid out in basically identical fashion. Stores could be found in the same places, but the identity of those stores varied. Some stores were in all three cities, some were in two, and some were unique. Participants were asked to memorize the layouts, and those who got things more than 80% correct ran through the test again, only this time their brain activity was monitored through MRI.

In general, brain activity was similar for the participants; after all, they were recalling similar environments. However, when asked about stores that appeared in multiple cities, brain activity varied dramatically. This indicated to the researchers that the brain was recalling shared stores as if they were more dissimilar than two completely disparate and unique stores, a concept often known to brain scientists as “repulsion.” It also indicates that the memories regarding shared environments are stored in the prefrontal cortex, not the hippocampus, which typically handles memory.

The researchers plan to apply this information to questions about diseases such as Alzheimer’s, so the next time you get turned around in a weirdly unfamiliar grocery store, just think: “It’s okay, I’m helping to solve a terrible brain disease.”
 

The real endgame: Friction is the winner

Spoiler alert! If you haven’t seen “Avengers: Infinity War” yet, we’re about to ruin it for you.

Georgia Tech

For those still with us, here’s the spoiler: Thanos would not have been able to snap his fingers while wearing the Infinity Gauntlet.

Saad Bhamla, PhD, of Georgia Tech University’s school of chemical and biomolecular engineering, had been studying powerful and ultrafast motions in living organisms along with several colleagues before the movie came out in 2018, and when they saw the finger-snapping scene it got them wondering.

Being scientists of course, they had no choice. They got out their high-speed imaging equipment, automated image processing software, and dynamic force sensors and analyzed finger snaps, paying close attention to friction by covering fingers with “different materials, including metallic thimbles to simulate the effects of trying to snap while wearing a metallic gauntlet, much like Thanos,” according to a statement on Eurekalert.

With finger snaps, it’s all about the rotational velocity. The angular acceleration involved is the fastest ever measured in a human, with a professional baseball pitcher’s throwing arm a distant second.

Dr. Bhamla’s reaction to their work explains why scientists are the ones doing science. “When I first saw the data, I jumped out of my chair,” he said in the written statement.

Rotational velocities dropped dramatically when the friction-reducing thimbles were used, so there was no snap. Which means that billions and billions of fictional lives could have been saved if the filmmakers had just talked to the right scientist.

That scientist, clearly, is Dr. Bhamla, who said that “this is the only scientific project in my lab in which we could snap our fingers and get data.”

Drinking coffee or tea is associated with reduced risk for stroke and dementia, with the biggest benefit associated with consuming both beverages, new research suggests.

Investigators found that individuals who drank two to three cups of coffee and two to three cups of tea per day had a 30% decrease in incidence of stroke and a 28% lower risk for dementia compared with those who did not.

“From a public health perspective, because regular tea and coffee drinkers comprise such a large proportion of the population and because these beverages tend to be consumed habitually throughout adult life, even small potential health benefits or risks associated with tea and coffee intake may have important public health implications,” the investigators wrote.

The study was published online Nov. 16 in PLOS Medicine.
 

Synergistic effect?

Whereas earlier studies have shown significant health benefits from moderate coffee and tea intake separately, few have examined the effect of drinking both.

Researchers enrolled 365,682 participants from the UK Biobank for the analysis of coffee and tea consumption and stroke and dementia risk and 13,352 participants for the analysis of poststroke dementia.

During a median follow-up of 11.4 years, 2.8% of participants experienced a stroke and 1.4% developed dementia.

After adjustment for confounders, stroke risk was 10% lower in those who drank a half-cup to a cup of coffee per day (P < .001) and 8% lower in those who had more than two cups a day (P = .009). Tea drinkers who had more than two cups a day saw a 16% reduction in stroke (P < .001).

Those who drank both coffee and tea during the day saw the greatest benefit. Drinking two to three cups of coffee and two to three cups of tea lowered stroke risk by 32% (P < .001) and dementia risk by 28% (P = .002).

Drinking both beverages offered significantly greater benefits than drinking just coffee or tea alone, with an 11% lower risk for stroke (P < .001), an 8% lower risk for dementia (P = .001), and 18% lower risk for vascular dementia (P = .001).

Among those participants who experienced a stroke during the follow-up period, drinking two to three cups of coffee was associated with 20% lower risk for poststroke dementia (P = .044), and for those who drank both coffee and tea (half to one cup of coffee and two to three cups of tea per day) the risk for poststroke dementia was lowered by 50% (P =.006).

There was no significant association between coffee and tea consumption and risk for hemorrhagic stroke or Alzheimer’s disease.

The study was funded by the National Natural Science Foundation of China. The authors have disclosed no relevant financial relationships.

A regimen of daily, low-dose aspirin failed to produce a significant reduction in the incidence of dementia or cognitive impairment in ASCEND, a randomized, multicenter trial with more than 15,000 people with diabetes followed for an average of more than 9 years, but the results hinted at enough of a benefit to warrant further study, some experts said.

A second metric used a broader outcome definition that tracked EHR entries for not only dementia but also diagnoses of cognitive impairment, delirium, confusion, prescription of dementia medications, and referral to a memory clinic or geriatric psychiatry. The third assessment was a cognitive-function test given to participants at the end of follow-up, but only 58% of enrolled participants completed this part of the study, and it’s also possible that some subjects missed this assessment because of dementia onset. These limitations hamper clear interpretation of this third metric, Dr. Armitage said.

The main findings for the other two, more reliable measures of incident dementia or cognitive deterioration showed a nonsignificant 9% relative risk reduction linked with aspirin use compared with placebo for the more inclusive endpoint, and a nonsignificant 11% relative risk reduction with aspirin using the narrow definition for dementia only, she reported. The third method, a directly administered assessment of dementia and cognition, also showed a small, nonsignificant effect from daily aspirin use relative to placebo.

Results can’t rule out modest aspirin effect

Dr. Armitage highlighted that the two more reliable measures both appeared to rule out risk for neurologic harm from aspirin because the upper limit of the 95% confidence interval for relative effect reached only 1.02 using the broad outcomes, and 1.06 for the narrower endpoint of dementia only. On the other hand, focus on the low end of the 95% confidence interval suggested potentially meaningful benefits, with a possible reduction by aspirin in events relative to placebo of as much as 19% by the broad outcome definition and by 25% with the narrow definition.

“Even if it was only a 15% relative risk reduction, that would be important,” given the high dementia incidence worldwide, Dr. Armitage said during a press briefing. “It’s entirely possible, with our results, that a modest benefit exists.”

This take on the findings won some support. Further studies with more people, longer follow-up, and perhaps enrolling a more selected, higher risk cohort may better address potential neurologic benefit from aspirin, suggested Amytis Towfighi, MD, a stroke neurologist and professor of neurology at the University of Southern California, Los Angeles, and a designated discussant for the report.

The result “was rather encouraging. I was a little surprised” by the findings, commented Chrystie M. Ballantyne, MD, professor and director of the Center for Cardiometabolic Disease Prevention at Baylor College of Medicine, Houston, also a discussant.

The results “don’t mean that no one benefits from aspirin. Perhaps certain people at risk would benefit from dementia protection. It’s an open question,” commented Erin D. Michos, MD, director of Women’s Cardiovascular Health at Johns Hopkins Medicine, Baltimore.

Evidence against routine, widespread primary prevention with aspirin

ASCEND had the primary goal of assessing a daily, 100-mg aspirin dose for its safety and efficacy for preventing vascular events such as MIs and ischemic strokes in 15,480 people with diabetes who were at least 40 years old at enrollment and had no history of cardiovascular disease. The main results came out in 2018 and showed that while aspirin produced a significant benefit by reducing thrombotic events, it also resulted in significantly more major bleeding events compared with placebo, and overall the magnitude of benefit roughly matched magnitude of risk.

These findings, along with similar results from two other high-profile aspirin studies reported at about the same time (ASPREE, and ARRIVE), led to recommendations from groups like the U.S. Preventive Services Task Force and from the American College of Cardiology and American Heart Association that caution against widespread, routine aspirin use for primary prevention of atherosclerotic cardiovascular disease events in most adults.

The groups instead endorsed a tailored strategy of targeting aspirin to people with a higher than average risk for ischemic thrombotic events and a lower than average bleeding risk. (The most recent aspirin recommendations from the USPSTF, currently in draft form, substantially curtail aspirin’s appropriate use, eliminating it in those over age 60 years.)

However, experts and prevailing practice recommendations continue to endorse routine aspirin use for secondary prevention in patients with an established history of cardiovascular disease.

The new findings reported by Dr. Armitage came from additional analyses of dementia and cognitive impairment overlaid on the main ASCEND outcome analyses. ASCEND actively treated and followed study participants for an average of 7.4 years, then researchers tracked further dementia outcomes based on medical-record entries for an average of another 1.8 years.

ASCEND received partial funding or support from Abbott, Bayer, Mylan, and Solvay. Dr. Armitage had no disclosures. Dr. Towfighi, Dr. Khera, and Dr. Michos had no disclosures. Dr. Ballantyne has had financial relationships with numerous companies.
