Nurses’ cohort study: Endometriosis elevates stroke risk
Women who’ve had endometriosis carry an elevated risk of stroke with them for the rest of their lives, with the greatest risk found in women who’ve had a hysterectomy with an oophorectomy, according to a cohort study of the Nurses’ Health Study.
“This is yet additional evidence that those girls and women with endometriosis are having effects across their lives and in multiple aspects of their health and well-being,” senior study author Stacey A. Missmer, ScD, of the Michigan State University, East Lansing, said in an interview. “This is not, in quotes ‘just a gynecologic condition,’ ” Dr. Missmer added. “It is not strictly about the pelvic pain or infertility, but it really is about the whole health across the life course.”
The study included 112,056 women in the NHSII cohort study who were followed from 1989 to June 2017, documenting 893 incident cases of stroke among them – an incidence of less than 1%. Endometriosis was reported in 5,244 women, and 93% of the cohort were White.
Multivariate adjusted models showed that women who had laparoscopically confirmed endometriosis had a 34% greater risk of stroke than women without a history of endometriosis. Leslie V. Farland, ScD, of the University of Arizona, Tucson, was lead author of the study.
While previous studies have demonstrated an increased risk of cardiovascular disease, heart attack, angina, and atherosclerosis in women who’ve had endometriosis, this is the first study that has confirmed an additional increased risk of stroke, Dr. Missmer said.
Another novel finding, Dr. Missmer said, is that while the CVD risks for these women “seem to peak at an earlier age,” the study found no age differences for stroke risk. “That also reinforces that these stroke events are often happening in an age range typical for stroke, which is further removed from when women are thinking about their gynecologic health specifically.”
These findings don’t translate into a significantly greater risk for stroke overall in women who’ve had endometriosis, Dr. Missmer said. She characterized the risk as “not negligible, but it’s not a huge increased risk.” The absolute risk is still fairly low, she said.
“We don’t want to give the impression that all women with endometriosis need to be panicked or fearful about stroke, she said. “Rather, the messaging is that this yet another bit of evidence that whole health care for those with endometriosis is important.”
Women who’ve had endometriosis and their primary care providers need to be attuned to stroke risk, she said. “This is a critical condition that primary care physicians need to engage around, and perhaps if symptoms related to cardiovascular and cerebrovascular disease emerge in their patients, they need to be engaging cardiology and similar types of support. This is not just about the gynecologists.”
The study also explored other factors that may contribute to stroke risk, with the most significant being hysterectomy with bilateral oophorectomy, Dr. Missmer said.
This study was unique because it used laparoscopically confirmed rather than self-reported endometriosis, said Louise D. McCullough, MD, neurology chair at the University of Texas Health Science Center, Houston. Another strength of the study she noted was its longitudinal design, although the cohort study design yielded a low number of stroke patients.
“Regardless, I do think it was a very important study because we have a growing recognition about how women’s health and factors such as pregnancy, infertility, parity, complications, and gonadal hormones such as estrogen can influence a woman’s stroke risk much later in life,” Dr. McCullough said in an interview.
Future studies into the relationship between endometriosis and CVD and stroke risk should focus on the mechanism behind the inflammation that occurs in endometriosis, Dr. McCullough said. “Part of it is probably the loss of hormones if a patient has to have an oophorectomy, but part of it is just what do these diseases do for a woman’s later risk – and for primary care physicians, ob.gyns., and stroke neurologists to recognize that these are questions we should ask: Have you ever had eclampsia or preeclampsia? Did you have endometriosis? Have you had miscarriages?”
The study received funding from the Eunice Kennedy Shriver National Institute of Child Health and Human Development and the National Institute for Neurological Disorders and Stroke. Dr. Missmer disclosed relationships with Shanghai Huilun Biotechnology, Roche, and AbbVie. Dr. McCullough has no relevant disclosures.

CDC warns about potentially deadly virus in infants
The potentially fatal parechovirus is now circulating in multiple states, causing fevers, seizures, and sepsis-like symptoms, including confusion and extreme pain, according to the CDC.
Human parechoviruses are common in children and most have been infected before they start kindergarten, the CDC said. Between 6 months and 5 years of age, symptoms include an upper respiratory tract infection, fever, and rash.
But infants younger than 3 months may have more serious, and possibly fatal, infections. They may get “sepsis-like illness, seizures, and meningitis or meningoencephalitis, particularly in infants younger than 1 month,” the CDC said. At least one newborn has reportedly died from the infection.
Parechovirus can spread like other common germs, from feces that are later ingested – likely due to poor handwashing – and through droplets sent airborne by coughing or sneezing. It can be transmitted by people both with and without symptoms of the infection.
The microbe can reproduce for 1-3 weeks in the upper respiratory tract and up to 6 months in the gastrointestinal tract, the CDC said.
Kristina Angel Bryant, MD, a pediatric infectious disease specialist at the University of Louisville Hospital, says parechoviruses often cause rashes on the hands and feet, which some experts refer to as “mittens and booties.”
The CDC is urging doctors to test for parechovirus if they recognize these symptoms in infants if there is no other explanation for what might be distressing them.
There is no specific treatment for parechovirus. And with no standard testing system in place, experts are unsure if the number of parechovirus cases is higher in 2022 than in previous years.
The message for parents, Dr. Bryant says, is: Don’t panic. “This is not a new virus.”
“One of the most common symptoms is fever, and in some kids, that is the only symptom,” she says. “Older infants and toddlers may have only cold symptoms, and some kids have no symptoms at all.”
Parents can take the usual steps to protect their child from the viral illness, including diligent handwashing and having less contact with people who are sick, Dr. Bryant says.

Alcohol’s detrimental impact on the brain explained?
Results of a large observational study suggest brain iron accumulation is a “plausible pathway” through which alcohol negatively affects cognition, study Anya Topiwala, MD, PhD, senior clinical researcher, Nuffield Department of Population Health, University of Oxford, England, said in an interview.
Study participants who drank 56 grams of alcohol a week had higher brain iron levels. The U.K. guideline for “low risk” alcohol consumption is less than 14 units weekly, or 112 grams.
“We are finding harmful associations with iron within those low-risk alcohol intake guidelines,” said Dr. Topiwala.
The study was published online in PLOS Medicine.
Early intervention opportunity?
Previous research suggests higher brain iron may be involved in the pathophysiology of Alzheimer’s and Parkinson’s diseases. However, it’s unclear whether deposition plays a role in alcohol’s effect on the brain and if it does, whether this could present an opportunity for early intervention with, for example, chelating agents.
The study included 20,729 participants in the UK Biobank study, which recruited volunteers from 2006 to 2010. Participants had a mean age of 54.8 years, and 48.6% were female.
Participants self-identified as current, never, or previous alcohol consumers. For current drinkers, researchers calculated the total weekly number of U.K. units of alcohol consumed. One unit is 8 grams. A standard drink in the United States is 14 grams. They categorized weekly consumption into quintiles and used the lowest quintile as the reference category.
Participants underwent MRI to determine brain iron levels. Areas of interest were deep brain structures in the basal ganglia.
Mean weekly alcohol consumption was 17.7 units, which is higher than U.K. guidelines for low-risk consumption. “Half of the sample were drinking above what is recommended,” said Dr. Topiwala.
Alcohol consumption was associated with markers of higher iron in the bilateral putamen (beta, 0.08 standard deviation; 95% confidence interval, 0.06-0.09; P < .001), caudate (beta, 0.05; 95% CI, 0.04-0.07; P < .001), and substantia nigra (beta, 0.03; 95% CI; 0.02-0.05; P < .001).
Poorer performance
Drinking more than 7 units (56 grams) weekly was associated with higher susceptibility for all brain regions, except the thalamus.
Controlling for menopause status did not alter associations between alcohol and susceptibility for any brain region. This was also the case when excluding blood pressure and cholesterol as covariates.
There were significant interactions with age in the bilateral putamen and caudate but not with sex, smoking, or Townsend Deprivation Index, which includes such factors as unemployment and living conditions.
To gather data on liver iron levels, participants underwent abdominal imaging at the same time as brain imaging. Dr. Topiwala explained that the liver is a primary storage center for iron, so it was used as “a kind of surrogate marker” of iron in the body.
The researchers showed an indirect effect of alcohol through systemic iron. A 1 SD increase in weekly alcohol consumption was associated with a 0.05 mg/g (95% CI, 0.02-0.07; P < .001) increase in liver iron. In addition, a 1 mg/g increase in liver iron was associated with a 0.44 (95% CI, 0.35-0.52; P < .001) SD increase in left putamen susceptibility.
In this sample, 32% (95% CI, 22-49; P < .001) of alcohol’s total effect on left putamen susceptibility was mediated via higher systemic iron levels.
To minimize the impact of other factors influencing the association between alcohol consumption and brain iron – and the possibility that people with more brain iron drink more – researchers used Mendelian randomization that considers genetically predicted alcohol intake. This analysis supported findings of associations between alcohol consumption and brain iron.
Participants completed a cognitive battery, which included trail-making tests that reflect executive function, puzzle tests that assess fluid intelligence or logic and reasoning, and task-based tests using the “Snap” card game to measure reaction time.
Investigators found the more iron that was present in certain brain regions, the poorer participants’ cognitive performance.
Patients should know about the risks of moderate alcohol intake so they can make decisions about drinking, said Dr. Topiwala. “They should be aware that 14 units of alcohol per week is not a zero risk.”
Novel research
Commenting for this news organization, Heather Snyder, PhD, vice president of medical and scientific relations, Alzheimer’s Association, noted the study’s large size as a strength of the research.
She noted previous research has shown an association between higher iron levels and alcohol dependence and worse cognitive function, but the potential connection of brain iron levels, moderate alcohol consumption, and cognition has not been studied to date.
“This paper aims to look at whether there is a potential biological link between moderate alcohol consumption and cognition through iron-related pathways.”
The authors suggest more work is needed to understand whether alcohol consumption impacts iron-related biologies to affect downstream cognition, said Dr. Snyder. “Although this study does not answer that question, it does highlight some important questions.”
Study authors received funding from Wellcome Trust, UK Medical Research Council, National Institute for Health Research (NIHR) Oxford Biomedical Research Centre, BHF Centre of Research Excellence, British Heart Foundation, NIHR Cambridge Biomedical Research Centre, U.S. Department of Veterans Affairs, China Scholarship Council, and Li Ka Shing Centre for Health Information and Discovery. Dr. Topiwala has disclosed no relevant financial relationships.

She noted previous research has shown an association between higher iron levels and alcohol dependence and worse cognitive function, but the potential connection of brain iron levels, moderate alcohol consumption, and cognition has not been studied to date.
“This paper aims to look at whether there is a potential biological link between moderate alcohol consumption and cognition through iron-related pathways.”
The authors suggest more work is needed to understand whether alcohol consumption impacts iron-related biologies to affect downstream cognition, said Dr. Snyder. “Although this study does not answer that question, it does highlight some important questions.”

Moderate drinking shows more benefit for older vs. younger adults
The health risks and benefits of moderate alcohol consumption are complex and remain a hot topic of debate. The data suggest that small amounts of alcohol may reduce the risk of certain health outcomes over time, but increase the risk of others, wrote Dana Bryazka, MS, a researcher at the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, Seattle, and colleagues, in a paper published in the Lancet.
“The amount of alcohol that minimizes health loss is likely to depend on the distribution of underlying causes of disease burden in a given population. Since this distribution varies widely by geography, age, sex, and time, the level of alcohol consumption associated with the lowest risk to health would depend on the age structure and disease composition of that population,” the researchers wrote.
“We estimate that 1.78 million people worldwide died due to alcohol use in 2020,” Ms. Bryazka said in an interview. “It is important that alcohol consumption guidelines and policies are updated to minimize this harm, particularly in the populations at greatest risk,” she said.
“Existing alcohol consumption guidelines frequently vary by sex, with higher consumption thresholds set for males compared to females. Interestingly, with the currently available data we do not see evidence that risk of alcohol use varies by sex,” she noted.
Methods and results
In the study, the researchers conducted a systematic analysis of burden-weighted dose-response relative risk curves across 22 health outcomes. They used disease rates from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2020 for the years 1990-2020 for 21 regions, including 204 countries and territories. The data were analyzed by 5-year age group, sex, and year for individuals aged 15-95 years and older. The researchers estimated the theoretical minimum risk exposure level (TMREL) and nondrinker equivalent (NDE), meaning the amount of alcohol at which the health risk equals that of a nondrinker.
One standard drink was defined as 10 g of pure alcohol, equivalent to a small glass of red wine (100 mL or 3.4 fluid ounces) at 13% alcohol by volume, a can or bottle of beer (375 mL or 12 fluid ounces) at 3.5% alcohol by volume, or a shot of whiskey or other spirits (30 mL or 1.0 fluid ounces) at 40% alcohol by volume.
Overall, the TMREL was low regardless of age, sex, time, or geography, and varied from 0 to 1.87 standard drinks per day. However, it was lowest for males aged 15-39 years (0.136 drinks per day) and only slightly higher for females aged 15-39 (0.273), representing 1-2 tenths of a standard drink.
For adults aged 40 and older without any underlying health conditions, drinking a small amount of alcohol may provide some benefits, such as reducing the risk of ischemic heart disease, stroke, and diabetes, the researchers noted. In general, for individuals aged 40-64 years, TMRELs ranged from about half a standard drink per day (0.527 drinks for males and 0.562 standard drinks per day for females) to almost two standard drinks (1.69 standard drinks per day for males and 1.82 for females). For those older than 65 years, the TMRELs represented just over 3 standard drinks per day (3.19 for males and 3.51 for females). For individuals aged 40 years and older, the distribution of disease burden varied by region, but was J-shaped across all regions, the researchers noted.
The researchers also found that those individuals consuming harmful amounts of alcohol were most likely to be aged 15-39 (59.1%) and male (76.9%).
The study findings were limited by several factors including the observational design and lack of data on drinking patterns, such as binge drinking, the researchers noted. Other limitations include the lack of data reflecting patterns of alcohol consumption during the COVID-19 pandemic, and exclusion of outcomes often associated with alcohol use, such as depression, anxiety, and dementia, that might reduce estimates of TMREL and NDE.
However, the results add to the ongoing discussion of the relationship between moderate alcohol consumption and health, the researchers said.
“The findings of this study support the development of tailored guidelines and recommendations on alcohol consumption by age and across regions and highlight that existing low consumption thresholds are too high for younger populations in all regions,” they concluded.
Consider individual factors when counseling patients
The takeaway message for primary care is that alcohol consumed in moderation can reduce the risk of ischemic heart disease, stroke, and diabetes, Ms. Bryazka noted. “However, it also increases the risk of many cancers, intentional and unintentional injuries, and infectious diseases like tuberculosis,” she said. “Of these health outcomes, young people are most likely to experience injuries, and as a result, we find that there are significant health risks associated with consuming alcohol for young people. Among older individuals, the relative proportions of these outcomes vary by geography, and so do the risks associated with consuming alcohol,” she explained.
“Importantly, our analysis was conducted at the population level; when evaluating risk at the individual level, it is also important to consider other factors such as the presence of comorbidities and interactions between alcohol and medications,” she emphasized.
Health and alcohol interaction is complicated
“These findings seemingly contradict a previous [Global Burden of Diseases, Injuries, and Risk Factors Study] estimate published in The Lancet, which emphasized that any alcohol use, regardless of amount, leads to health loss across populations,” wrote Robyn Burton, PhD, and Nick Sheron, MD, both of King’s College, London, in an accompanying comment.
However, the novel methods of weighting relative risk curves according to levels of underlying disease drive the difference in results, along with disaggregated estimates by age, sex, and region, they said.
“Across most geographical regions in this latest analysis, injuries accounted for most alcohol-related harm in younger age groups. This led to a minimum risk level of zero, or very close to zero, among individuals aged 15-39 years across all geographical regions,” which is lower than the level for older adults because of the shift in alcohol-related disease burden towards cardiovascular disease and cancers, they said. “This highlights the need to consider existing rates of disease in a population when trying to determine the total harm posed by alcohol,” the commentators wrote.
In an additional commentary, Tony Rao, MD, a visiting clinical research fellow in psychiatry at King’s College, London, noted that “the elephant in the room with this study is the interpretation of risk based on outcomes for cardiovascular disease – particularly in older people. We know that any purported health benefits from alcohol on the heart and circulation are balanced out by the increased risk from other conditions such as cancer, liver disease, and mental disorders such as depression and dementia,” Dr. Rao said. “If we are to simply draw the conclusion that older people should continue or start drinking small amounts because it protects against diseases affecting heart and circulation – which still remains controversial – other lifestyle changes or the use of drugs targeted at individual cardiovascular disorders seem like a less harmful way of improving health and wellbeing.”
Data can guide clinical practice
No previous study has examined the effect of the theoretical minimum risk of alcohol consumption by geography, age, sex, and time in the context of background disease rates, said Noel Deep, MD, in an interview.
“This study enabled the researchers to quantify the proportion of the population that consumed alcohol in amounts that exceeded the thresholds by location, age, sex, and year, and this can serve as a guide in our efforts to target the control of alcohol intake by individuals,” said Dr. Deep, a general internist in private practice in Antigo, Wisc. He also serves as chief medical officer and a staff physician at Aspirus Langlade Hospital in Antigo.
The first take-home message for clinicians is that even low levels of alcohol consumption can have deleterious effects on the health of patients, and patients should be advised accordingly based on the prevalence of diseases in that community and geographic area, Dr. Deep said. “Secondly, clinicians should also consider the risk of alcohol consumption on all forms of health impacts in a given population rather than just focusing on alcohol-related health conditions,” he added.
“This study provides us with the data to tailor our efforts in educating the clinicians and the public about the relationship between alcohol consumption and disease outcomes based on the observed disease rates in each population,” Dr. Deep explained. “The data should provide another reason for physicians to advise their younger patients, especially the younger males, to avoid or minimize alcohol use,” he said. The data also can help clinicians formulate public health messaging and community education to reduce harmful alcohol use, he added.
As for additional research, Dr. Deep said he would like to see data on the difference in the health-related effects of alcohol in binge-drinkers vs. those who regularly consume alcohol on a daily basis. “It would probably also be helpful to figure out what type of alcohol is being studied and the quality of the alcohol,” he said.

Dr. Burton disclosed serving as a consultant to the World Health Organization European Office for the Prevention and Control of Noncommunicable Diseases. Dr. Sheron had no financial conflicts to disclose. Dr. Deep had no financial conflicts to disclose, but serves on the Editorial Advisory Board of Internal Medicine News.

Shift schedule today could worsen that stroke tomorrow
Body clocks and the shifting risks of stroke
Health care professionals, we’re sure, are no strangers to rotating shifts. And, as practitioners of the shiftly arts, you should know new research shows that working those kinds of hours can have lasting effects on your health. And it’s all based on your sleep-wake cycle.
In a study published in Neurobiology of Sleep and Circadian Rhythms, investigators at Texas A&M University looked at the effects of working these kinds of shifts for a long period of time and then returning to a regular 24-hour cycle later in life. The study piggybacks on a previous study, which showed that rats on shift schedules had more severe stroke outcomes than those who were on a 24-hour cycle.
The current study demonstrates that working rotating shifts does have a lasting effect, by way of messing with the sleep-wake cycle. Based on the research, the rats that performed those kinds of shifts never got back to a normal schedule. When strokes occurred, outcomes were much worse, and the females had a higher mortality rate and more severe functional deficits than the males.
Now for the “good” news: Even if you’re among those who haven’t worked a rotating shift, you may not be safe either.
People who have regular working hours have a tendency to take work home and stay up late, especially with so many moving to a remote-work model. And if you’re staying up late on the weekends you’re producing what lead author David J. Earnest, PhD, called “social jet lag,” which messes with your circadian rhythm to wind you down for sleep. All of these things can lead to the same kind of effects that working rotating shifts has on your health, he said in a written statement.
How do you combat this? Dr. Earnest recommended creating a sleep schedule and setting regular mealtimes. Also ease up on high-fat foods, drinking, and smoking. The connection between your brain and gut also could play a part in how severe a stroke can be.
So continue to work hard, but not too hard.
Got 3 minutes? You got time for culture
Much like a Krabby Patty, art is good for your soul. Seriously, staring at a 500-year-old painting may not seem like much, but research has proven time and again that going to a museum and looking at paintings by long-dead artists you probably know better as pizza-eating superhero turtles improves mood, stress, and well-being.
A couple of years ago, however, museums and art galleries ran into a big virus-shaped problem. You may have heard of it. All of a sudden it became a very bad idea for people to gather together in one building and huddle around the Mona Lisa, which, by the way, is a lot smaller in person than you might expect. But, rather than sit around with a bunch of priceless art for an indeterminate amount of time, museums brought their exhibits to the Internet so that people from all over the world could see great works from their couches.
This is absolutely a good thing for public access, but do these virtual art exhibits provide the same health benefits as going to a museum in person? That’s what a group of European researchers aimed to find out, and in a study published in Frontiers of Psychology, that’s exactly what they found.
Their directive to the 84 study participants was simple: Take a well-being survey, engage with either of a pair of online exhibits (a Monet painting and a display of Japanese culinary traditions) for just 3 minutes, then take another well-being assessment. The results were quite clear: Even just a couple of minutes of viewing art online improved all the well-being categories on the survey, such as lowering anxiety, negative mood, and loneliness, as well as increasing subjective well-being. Also, the more beautiful or meaningful a person found the art, the more their mood and well-being improved.
The researchers noted that these results could help access in places where access to art is limited, such as waiting rooms, hospitals, and rural areas. Let’s just hope it sticks to that, and that big businesses don’t take notice. Just imagine them plastering ads with classic Renaissance artworks. After all, art makes you feel good, and you know what else feels good on a hot summer day? An ice-cold Coca-Cola! By the way, we’re taking offers, advertising agencies. The LOTME staff can absolutely be bought.
Appetite for etymology
Today on “It’s a Thing,” we examine various states of hunger and what they should be called. Our first guest is that historically hungry royal person, King Henry VIII of England. Your majesty, have you ever been “hangry?”
KH8: First, let me thank you for inviting me on the show, Maurice. I’m a huge fan. A recent study done in the United Kingdom and Austria showed that “hunger is associated with greater levels of anger and irritability, as well as lower levels of pleasure,” according to a Eurekalert statement. So, yes, I have been “hangry.”
Maurice: Now to our next guest. Martha Stewart, can you add anything about that study?
Martha: Happy to, Maurice. The 64 participants used a smartphone app to record their hunger levels and emotional states five times a day for 21 days. It’s the first time that “hanger” was studied outside a lab, and it showed that hunger “was associated with 37% of the variance in irritability, 34% of the variance in anger, and 38% of the variance in pleasure recorded by the participants,” the investigators said in that statement.
Maurice: It’s official, then. Hangry is a thing, and we don’t need to put it in quotes anymore. Now let’s meet our third and final guest, Betty Crocker. Betty, I’m told you have a study to plug.
Betty: That’s right, Mo. Researchers at Tel Aviv University looked at survey data from almost 3,000 men and women and found that men ate 17% more food during the warmer months (March to September) than they did the rest of the year. Among women, however, caloric intake did not change.
KH8: I saw that study. Didn’t they put 27 people out in the sun and then take blood samples?
Betty: Indeed they did, Hank. After 25 minutes of sun exposure, the 13 men felt hungrier than before, but the 14 women did not. The men also had higher levels of ghrelin, an appetite-stimulating hormone, than the women.
Maurice: To sum all this up, then, we’ve got angry and hungry officially combining to make hangry, and now it looks like the sun is causing hunger in men, which makes them … sungry?
Martha: It’s a thing.

You stopped at the drive through at McDonald’s on the way home from work, and while you’re looking for something sweet in the refrigerator for dessert, you see that chicken breast that expires today.
Freezing meat that’s about to expire might be your go-to so it doesn’t go to waste, but it’s been found that SARS-CoV-2 can live in meat that’s been in the refrigerator or freezer for more than a month.
Researchers exposed chicken, beef, pork, and salmon to surrogate viruses that are similar to COVID but not as harmful and stored them in freezers at –4° F and in the refrigerator at 39.2° F. “We even found that the viruses could be cultured after [being frozen for] that length of time,” lead author Emily Bailey, PhD, of Campbell University in Buies Creek, N.C., said in Study Finds.
The team began its research after hearing of COVID-19 outbreaks where there were no reports of community transmission, such as in Southeast Asia. Tracing eventually led to packaged meats as the culprits in those cases. SARS-CoV-2 is able to replicate in the gut, as well as the respiratory tract, so it could affect the gut before respiratory symptoms start. It is crucial to ensure cross contamination doesn’t occur, and inadequate sanitation prior to packaging needs to be addressed, the investigators said.
Honestly, we didn’t think anything could survive in a freezer for that long, but SARS-CoV-2 is a fighter.
Body clocks and the shifting risks of stroke
Health care professionals, we’re sure, are no strangers to rotating shifts. And, as practitioners of the shiftly arts, you should know new research shows that working those kinds of hours can have lasting effects on your health. And it’s all based on your sleep-wake cycle.
In a study published in Neurobiology of Sleep and Circadian Rhythms, investigators at Texas A&M University looked at the effects of working these kinds of shifts for a long period of time and then returning to a regular 24-hour cycle later in life. The study piggybacks on a previous study, which showed that rats on shift schedules had more severe stroke outcomes than those who were on a 24-hour cycle.
The current study demonstrates that working rotating shifts does have a lasting effect, by way of messing with the sleep-wake cycle. Based on the research, the rats that performed those kinds of shifts never got back to a normal schedule. When strokes occurred, outcomes were much worse, and the females had a higher mortality rate and more severe functional deficits than the males.
Now for the “good” news: Even if you’re among those who haven’t worked a rotating shift, you may not be safe either.
People who have regular working hours have a tendency to take work home and stay up late, especially with so many moving to a remote-work model. And if you’re staying up late on the weekends you’re producing what lead author David J. Earnest, PhD, called “social jet lag,” which messes with your circadian rhythm to wind you down for sleep. All of these things can lead to the same kind of effects that working rotating shifts has on your health, he said in a written statement.
How do you combat this? Dr. Earnest recommended creating a sleep schedule and setting regular mealtimes. Also ease up on high-fat foods, drinking, and smoking. The connection between your brain and gut also could play a part in how severe a stroke can be.
So continue to work hard, but not too hard.
Got 3 minutes? You got time for culture
Much like a Krabby Patty, art is good for your soul. Seriously, staring at a 500-year-old painting may not seem like much, but research has proven time and again that going to a museum and looking at paintings by long-dead artists you probably know better as pizza-eating superhero turtles improves mood, stress, and well-being.
A couple of years ago, however, museums and art galleries ran into a big virus-shaped problem. You may have heard of it. All of a sudden it became a very bad idea for people to gather together in one building and huddle around the Mona Lisa, which, by the way, is a lot smaller in person than you might expect. But, rather than sit around with a bunch of priceless art for an indeterminate amount of time, museums brought their exhibits to the Internet so that people from all over the world could see great works from their couches.
This is absolutely a good thing for public access, but do these virtual art exhibits provide the same health benefits as going to a museum in person? That’s what a group of European researchers aimed to find out, and in a study published in Frontiers of Psychology, that’s exactly what they found.
Their directive to the 84 study participants was simple: Take a well-being survey, engage with either of a pair of online exhibits (a Monet painting and a display of Japanese culinary traditions) for just 3 minutes, then take another well-being assessment. The results were quite clear: Even just a couple of minutes of viewing art online improved all the well-being categories on the survey, such as lowering anxiety, negative mood, and loneliness, as well as increasing subjective well-being. Also, the more beautiful or meaningful a person found the art, the more their mood and well-being improved.
The researchers noted that these results could help access in places where access to art is limited, such as waiting rooms, hospitals, and rural areas. Let’s just hope it sticks to that, and that big businesses don’t take notice. Just imagine them plastering ads with classic Renaissance artworks. After all, art makes you feel good, and you know what else feels good on a hot summer day? An ice-cold Coca-Cola! By the way, we’re taking offers, advertising agencies. The LOTME staff can absolutely be bought.
Appetite for etymology
Today on “It’s a Thing,” we examine various states of hunger and what they should be called. Our first guest is that historically hungry royal person, King Henry VIII of England. Your majesty, have you ever been “hangry?”
KH8: First, let me thank you for inviting me on the show, Maurice. I’m a huge fan. A recent study done in the United Kingdom and Austria showed that “hunger is associated with greater levels of anger and irritability, as well as lower levels of pleasure,” according to a Eurekalert statement. So, yes, I have been “hangry.”
Maurice: Now to our next guest. Martha Stewart, can you add anything about that study?
Martha: Happy to, Maurice. The 64 participants used a smartphone app to record their hunger levels and emotional states five times a day for 21 days. It’s the first time that “hanger” was studied outside a lab, and it showed that hunger “was associated with 37% of the variance in irritability, 34% of the variance in anger, and 38% of the variance in pleasure recorded by the participants,” the investigators said in that statement.
Maurice: It’s official, then. Hangry is a thing, and we don’t need to put it in quotes anymore. Now let’s meet our third and final guest, Betty Crocker. Betty, I’m told you have a study to plug.
Betty: That’s right, Mo. Researchers at Tel Aviv University looked at survey data from almost 3,000 men and women and found that men ate 17% more food during the warmer months (March to September) than they did the rest of the year. Among women, however, caloric intake did not change.
KH8: I saw that study. Didn’t they put 27 people out in the sun and then take blood samples?
Betty: Indeed they did, Hank. After 25 minutes of sun exposure, the 13 men felt hungrier than before, but the 14 women did not. The men also had higher levels of ghrelin, an appetite-stimulating hormone, than the women.
Maurice: To sum all this up, then, we’ve got angry and hungry officially combining to make hangry, and now it looks like the sun is causing hunger in men, which makes them … sungry?
Martha: It’s a thing.

‘Striking’ jump in cost of brand-name epilepsy meds
, a new analysis shows.
After adjustment for inflation, the cost of a 1-year supply of brand-name ASMs grew 277%, while generics became 42% less expensive.
“Our study makes transparent striking trends in brand name prescribing patterns,” the study team wrote.
Since 2010, the costs for brand-name ASMs have “consistently” increased. Costs were particularly boosted by increases in prescriptions for lacosamide (Vimpat), in addition to a “steep increase in the cost per pill, with brand-name drugs costing 10 times more than their generic counterparts,” first author Samuel Waller Terman, MD, of the University of Michigan, Ann Arbor, added in a news release.
The study was published online in Neurology.
Is a 10-fold increase in cost worth it?
To evaluate trends in ASM prescriptions and costs, the researchers used a random sample of 20% of Medicare beneficiaries with coverage from 2008 to 2018. There were 77,000 to 133,000 patients with epilepsy each year.
Over time, likely because of increasing availability of generics, brand-name ASMs made up a smaller proportion of pills prescribed, from 56% in 2008 to 14% in 2018, but still made up 79% of prescription drug costs in 2018.
The annual cost of brand-name ASMs rose from $2,800 in 2008 to $10,700 in 2018, while the cost of generic drugs decreased from $800 to $460 during that time.
An increased number of prescriptions for lacosamide was responsible for 45% of the total increase in brand-name costs.
As of 2018, lacosamide comprised 30% of all brand-name pill supply (followed by pregabalin, at 15%) and 30% of all brand-name costs (followed by clobazam and pregabalin, both at 9%), the investigators reported.
Brand-name antiepileptic drug costs decreased from 2008 to 2010, but after the introduction of lacosamide, total brand-name costs steadily rose from $72 million in 2010 (in 2018 dollars) to $256 million in 2018, they noted.
Because the dataset consists of a 20% random Medicare sample, total Medicare costs for brand-name ASMs for beneficiaries with epilepsy alone likely rose from roughly $360 million in 2010 to $1.3 billion in 2018, they added.
“Clinicians must remain cognizant of this societal cost magnitude when judging whether the 10-fold increased expense per pill for brand name medications is worth the possible benefits,” they wrote.
“While newer-generation drugs have potential advantages such as limited drug interactions and different side effect profiles, there have been conflicting studies on whether they are cost effective,” Dr. Terman noted in a news release.
A barrier to treatment
The authors of an accompanying editorial propose that the problem of prescription drug costs could be solved through a combination of competition and government regulation of prices. Patients and physicians are the most important stakeholders in this issue.
“When something represents 14% of the total use, but contributes 79% of the cost, it would be wise to consider alternatives, assuming that these alternatives are not of lower quality,” wrote Wyatt Bensken, with Case Western Reserve University, Cleveland, and Iván Sánchez Fernández, MD, with Boston Medical Center.
“When there are several ASMs with a similar mechanism of action, similar efficacy, similar safety and tolerability profile, and different costs, it would be unwise to choose the more expensive alternative just because it is newer,” they said.
This study, they added, provides data to “understand, and begin to act, on the challenging problem of the cost of prescription ASMs. After all, what is the point of having a large number of ASMs if their cost severely limits their use?”
A limitation of the study is that only Medicare prescription claims were included, so the results may not apply to younger patients with private insurance.
The study received no direct funding. The authors and editorialists have disclosed no relevant financial relationships.

Access to certified stroke centers divided by race, income
Hospitals in low-income and rural areas of the United States are much less likely to adopt stroke certification than hospitals in high-income and urban communities, a new study shows.
Further, other results showed that, after adjustment for population and hospital size, access to stroke-certified hospitals is significantly lower in Black, racially segregated communities.
The study was published online in JAMA Neurology.
Noting that stroke-certified hospitals provide higher-quality stroke care, the authors, led by Yu-Chu Shen, PhD, Naval Postgraduate School, Monterey, Calif., conclude that: “Our findings suggest that structural inequities in stroke care may be an important consideration in eliminating stroke disparities for vulnerable populations.”
In an audio interview on the JAMA Neurology website, senior author Renee Y. Hsia, MD, University of California, San Francisco, said: “Our findings show there are clear disparities in which communities are getting access to stroke certified hospitals.”
She called for more help for hospitals in underserved areas to obtain stroke certification.
Dr. Hsia explained that hospitals can seek certification at their own expense and that although stroke care is expensive, it is also lucrative in terms of reimbursement. So it tends to be the private for-profit hospitals that seek these certifications. “If you are a county hospital on a really tight budget, you’re not going to have the extra cash on hand to be applying for stroke certification,” she commented.
This can result in an increase in hospitals with stroke certification – but not in the areas that need it the most.
Dr. Hsia points out that this has happened in cardiac care. One study showed a 44% increase in hospitals providing percutaneous coronary intervention over a 10-year period, but the percentage of the population that had better access increased by less than 1%.
“In general, in the United States we have a mentality that ‘more is better,’ and because there is no government regulation in health care, any time a hospital applies for these specialized services we just generally think that’s a good thing. But this might not always be the case,” Dr. Hsia noted. “We have a very market-based approach, and this doesn’t lead to equity. It leads to profit maximization, and that is not synonymous with what’s good for patients or populations.”
She suggested that in future the process of certification should include some consideration of how it will affect population-based equity.
“Rather than rubber stamping an application just because hospitals have certain resources, we need to ask what the benefit is of providing this service,” Dr. Hsia said. “Does this community really need it? If not, maybe we should invest these resources into helping a hospital in a community that needs it more.”
Dr. Hsia explained that she and her colleagues conducted their study to investigate whether there were structural issues that might be contributing to disparities in stroke care.
“We like to think emergency stroke care is equitable. Anyone can call 911 or go the emergency room. But, actually, there is a big disparity on who receives what type of care,” she said. “We know Black patients are less likely to receive thrombolytics and mechanical thrombectomy compared to White patents. And wealthy patients are more likely to receive thrombectomy compared to patients from the poorest zip codes.”
She said there is a tendency to think this is a result of some sort of bias on the part of health care professionals. “We wanted to look deep down in the system and whether the built environment of health care supply and geographic distribution of services contributed to access and treatment inequities.”
The study combined a dataset of hospital stroke certification from all general acute nonfederal hospitals in the continental United States from January 2009 to December 2019. National, hospital, and census data were used to identify historically underserved communities by racial and ethnic composition, income distribution, and rurality.
A total of 4,984 hospitals were assessed. Results showed that over the 11-year study period, the number of hospitals with stroke certification grew from 961 (19%) to 1,763 (36%).
Without controlling for population and hospital size, hospitals in predominantly Black, racially segregated areas were 1.67-fold more likely to adopt stroke care of any level than those in predominantly non-Black, racially segregated areas (hazard ratio, 1.67; 95% confidence interval, 1.41-1.97).
However, after adjustment for population and hospital size, the likelihood of adopting stroke care among hospitals serving Black, racially segregated communities was significantly lower than among those serving non-Black, racially segregated communities (HR, 0.74; 95% CI, 0.62-0.89).
“In other words, on a per-capita basis, a hospital serving a predominantly Black, racially segregated community was 26% less likely to adopt stroke certification of any level than a hospital in a predominantly non-Black, racially segregated community,” the authors state.
In terms of socioeconomic factors, hospitals serving low-income, economically integrated (HR, 0.23) and low-income, economically segregated (HR, 0.29) areas were far less likely to adopt any level of stroke care certification than hospitals serving high-income areas, regardless of income segregation.
Rural hospitals were also much less likely to adopt any level of stroke care than urban hospitals (HR, 0.10).
“Our results suggest that it might be necessary to incentivize hospitals operating in underserved communities to seek stroke certification or to entice hospitals with higher propensity to adopt stroke care to operate in such communities so access at the per-patient level becomes more equitable,” the authors say.

Hospitals in low-income and rural areas of the United States are much less likely to adopt stroke certification than hospitals in high-income and urban communities, a new study shows.
Further, other results showed that, after adjustment for population and hospital size, access to stroke-certified hospitals is significantly lower in Black, racially segregated communities.
The study was published online in JAMA Neurology.
Noting that stroke-certified hospitals provide higher-quality stroke care, the authors, led by Yu-Chu Shen, PhD, Naval Postgraduate School, Monterey, Calif., conclude that: “Our findings suggest that structural inequities in stroke care may be an important consideration in eliminating stroke disparities for vulnerable populations.”
In an audio interview on the JAMA Neurology website, senior author Renee Y. Hsia, MD, University of California, San Francisco, said: “Our findings show there are clear disparities in which communities are getting access to stroke certified hospitals.”
She called for more help for hospitals in underserved areas to obtain stroke certification.
Dr. Hsia explained that hospitals can seek certification at their own expense and that although stroke care is expensive, it is also lucrative in terms of reimbursement. So it tends to be the private for-profit hospitals that seek these certifications. “If you are a county hospital on a really tight budget, you’re not going to have the extra cash on hand to be applying for stroke certification,” she commented.
This can result in an increase in hospitals with stroke certification – but not in the areas that need it the most.
Dr. Hsia points out that this has happened in cardiac care. One study showed a 44% increase in hospitals providing percutaneous coronary intervention over a 10-year period, but the percentage of the population that had better access increased by less than 1%.
“In general, in the United States we have a mentality that ‘more is better,’ and because there is no government regulation in health care, any time a hospital applies for these specialized services we just generally think that’s a good thing. But this might not always be the case,” Dr. Hsia noted. “We have a very market-based approach, and this doesn’t lead to equity. It leads to profit maximization, and that is not synonymous with what’s good for patients or populations.”
She suggested that in future the process of certification should include some consideration of how it will affect population-based equity.
“Rather than rubber stamping an application just because hospitals have certain resources, we need to ask what the benefit is of providing this service,” Dr. Hsia said. “Does this community really need it? If not, maybe we should invest these resources into helping a hospital in a community that needs it more.”
Dr. Hsia explained that she and her colleagues conducted their study to investigate whether there were structural issues that might be contributing to disparities in stroke care.
“We like to think emergency stroke care is equitable. Anyone can call 911 or go the emergency room. But, actually, there is a big disparity on who receives what type of care,” she said. “We know Black patients are less likely to receive thrombolytics and mechanical thrombectomy compared to White patents. And wealthy patients are more likely to receive thrombectomy compared to patients from the poorest zip codes.”
She said there is a tendency to think this is a result of some sort of bias on the part of health care professionals. “We wanted to look deep down in the system and whether the built environment of health care supply and geographic distribution of services contributed to access and treatment inequities.”
The study combined a dataset of hospital stroke certification from all general acute nonfederal hospitals in the continental United States from January 2009 to December 2019. National, hospital, and census data were used to identify historically underserved communities by racial and ethnic composition, income distribution, and rurality.
A total of 4,984 hospitals were assessed. Results showed that over the 11-year study period, the number of hospitals with stroke certification grew from 961 (19%) to 1,763 (36%).
Without controlling for population and hospital size, hospitals in predominantly Black, racially segregated areas were 1.67-fold more likely to adopt stroke care of any level than those in predominantly non-Black, racially segregated areas (hazard ratio, 1.67; 95% confidence interval, 1.41-1.97).
However, after adjustment for population and hospital size, the likelihood of adopting stroke care among hospitals serving Black, racially segregated communities was significantly lower than among those serving non-Black, racially segregated communities (HR, 0.74; 95% CI, 0.62-0.89).

PTSD may accelerate cognitive decline over time
, new research suggests.
In an analysis of more than 12,000 middle-aged women who had experienced at least one trauma in their lives, those with PTSD symptoms showed an approximately twofold faster decline in cognition during follow-up compared with those who did not have PTSD symptoms.
These associations were not fully explained by other known cognition-related factors such as depression, the researchers noted.
“PTSD may increase the risk of dementia by accelerating cognitive decline at midlife,” coinvestigator Jiaxuan Liu, a doctoral candidate at Harvard TH Chan School of Public Health, Boston, said in an interview.
“Our findings may suggest the value of earlier cognitive screening among individuals with PTSD and the importance of PTSD prevention and treatment across the lifespan,” she added.
The results were published online in JAMA Network Open.
Vital public health issue
“Cognitive decline at midlife and older is of vital public health interest,” Ms. Liu said. “It is a risk factor for a variety of poor health outcomes and strongly predicts Alzheimer’s disease and other dementias.
Although PTSD has been linked to lower cognitive function and dementia incidence, it has not been known whether it is associated with decline in cognitive function, she added.
“In addition, both PTSD and dementia are more common in women than men, so it’s important to understand a possible link,” Ms. Liu said.
Because no large-scale study had examined whether PTSD is associated with cognitive decline in women, the current researchers examined PTSD symptoms and their association with repeated measures of cognitive function among a large civilian trauma-exposed cohort of women aged 50-70 years at study baseline.
Participants were drawn from the Nurses’ Health Study II, a longitudinal study of a cohort of 116,429 U.S. female nurses who were between 25 and 42 years old at enrollment in 1989. Participants completed biennial questionnaires, with follow-up on an ongoing basis.
The current analysis included 12,270 trauma-exposed women (mean age at baseline, 61.1 years) who completed assessments every 1 or 12 months for up to 24 months after baseline. The mean follow-up time was 0.9 years.
In the study population, 95.9% were non-Hispanic White, 1.3% were Hispanic, 1% were Asian, 0.6% were Black, and 1.2% were classified as “other.”
Higher depression scores
Lifetime trauma exposure and PTSD symptoms were assessed from March 1, 2008, to Feb. 28, 2010, using the Short Screening Scale for DSM-IV PTSD.
In total, 67% of the participants reported experiencing PTSD symptoms. The women were divided into four groups, on the basis of symptom number: no PTSD symptoms (n = 4,052), one to three PTSD symptoms (n = 5,058), four to five PTSD symptoms (n = 2,018), and six to seven PTSD symptoms (n = 1,052).
The Cogstate Brief Battery, a validated and self-administered online cognitive assessment, was completed by participants between Oct. 3, 2014, and July 30, 2019. The researchers measured cognitive function with two composite scores: psychomotor speed and attention, and learning and working memory.
Covariates potentially associated with cognitive decline included demographic, educational, and behavior-related health factors such as body mass index, physical activity, cigarette smoking, diet quality, and alcohol consumption.
The researchers conducted secondary analyses that adjusted for symptoms and history of depression as well as the consequences of potential practice effects of taking the test multiple times.
Behavior-related health factors “did not substantially differ by PTSD symptom level,” the investigators noted. However, compared with women who did not have PTSD symptoms, those who had such symptoms had higher depressive symptom scores and higher rates of clinician-diagnosed depression.
Both cognitive composite scores improved through the follow-up period, “likely because of practice effects,” the researchers wrote. But after adjusting for practice effects, they found a decline over time in both composite scores.
Dose-related trajectories
Results showed that having more PTSD symptoms was associated with dose-related poorer cognitive trajectories.
After adjustment for demographic characteristics, women with the highest symptom level (six to seven symptoms) had a significantly worse rate of change in both composite domains of learning and working memory (beta = −0.08 SD/y; 95% confidence interval [CI], −0.11 to −0.04 SD/y; P < .001) and of psychomotor speed and attention (beta = −0.05 SD/y; 95% CI, −0.09 to −0.01 SD/y; P = .02) compared with women with no PTSD symptoms.
Women with four to five PTSD symptoms showed a worse rate of change in learning and working memory compared with those who had no symptoms, but not in psychomotor speed and attention. Women with one to three PTSD symptoms had cognitive scores similar to those of women without PTSD symptoms.
Notably, the associations of PTSD with cognitive change remained evident after additional adjustment for behavioral factors and health conditions – and were only “partially attenuated but still evident” after further adjustment for practice effects and comorbid depression, the investigators wrote.
“We thought PTSD might be associated with worse cognitive decline through health behaviors like smoking and alcohol drinking and higher risk of other health conditions like hypertension and depression,” Ms. Liu said.
However, those factors did not account for the current study’s findings, she noted.
“We could not determine why women with PTSD had faster cognitive decline than those without PTSD,” she said.
Ms. Liu suggested that PTSD “may have effects on the brain, such as altering brain structures and affecting brain immune function.” However, more research is needed “to investigate these mechanisms that might underlie the association we found between PTSD and cognitive decline,” she said.
Neurotoxic effect
In a comment, Howard Fillit, MD, cofounder and chief science officer of the Alzheimer’s Drug Discovery Foundation, said, “It is well known that stress is neurotoxic, and PTSD is a particularly serious form of stress.”
Dr. Fillit, clinical professor of geriatric medicine and palliative care, medicine, and neuroscience at Mount Sinai Hospital, New York, was not involved with the study.
“We tend to think of PTSD in postacute settings, such as soldiers returning from war,” he said. “This study contributes to our understanding of the long-term effects of PTSD on cognitive decline, measured objectively over time”
Dr. Fillit noted that an important implication is that, by increasing the risk for cognitive decline, PTSD also increases risk for Alzheimer’s disease. This leads to the “main take-home, which is that PTSD is a risk factor not only for cognitive decline but also for Alzheimer’s and related dementias,” he said.
However, this opens a potential therapeutic approach, Dr. Fillit added.
Because cortisol and other stress hormones drive the stress response, finding ways to block the neurotoxic effects of these hormones “might be a target to prevent cognitive decline and decrease Alzheimer’s disease risk,” he said.
The study was supported by grants from the National Institute of Mental Health and the National Institutes of Health. Ms. Liu and Dr. Fillit report no relevant financial relationships.

Scientists find brain mechanism behind age-related memory loss
Scientists at Johns Hopkins University have identified a mechanism in the brain behind age-related memory loss, expanding our knowledge of the inner workings of the aging brain and possibly opening the door to new Alzheimer’s treatments.
The researchers looked at the hippocampus, a part of the brain thought to store long-term memories.
Neurons there are responsible for a pair of memory functions – called pattern separation and pattern completion – that work together in young, healthy brains. These functions can swing out of balance with age, impacting memory.
The Johns Hopkins team may have discovered what causes this imbalance. Their findings – reported in a paper in the journal Current Biology – may not only help us improve dementia treatments, but even prevent or delay a loss of thinking skills in the first place, the researchers say.
Pattern separation vs. pattern completion
To understand how the hippocampus changes with age, the researchers looked at rats’ brains. In rats and in humans, pattern separation and pattern completion are present, controlled by neurons in the hippocampus.
As the name suggests, pattern completion is when you take a few details or fragments of information – a few notes of music, or the start of a famous movie quote – and your brain retrieves the full memory. Pattern separation, on the other hand, is being able to tell similar observations or experiences apart (like two visits to the same restaurant) to be stored as separate memories.
These functions occur along a gradient across a tiny region called CA3. That gradient, the study found, disappears with aging, said lead study author Hey-Kyoung Lee, PhD, an assistant research scientist at the university’s Zanvyl Krieger Mind/Brain Institute. “The main consequence of the loss,” Dr. Lee said, “is that pattern completion becomes more dominant in rats as they age.”
What’s happening in the brain
Neurons responsible for pattern completion occupy the “distal” end of CA3, while those in charge of pattern separation reside at the “proximal” end. Dr. Lee said prior studies had not examined the proximal and distal regions separately, as she and her team did in this study.
What was surprising, said Dr. Lee, “was that hyperactivity in aging was observed toward the proximal CA3 region, not the expected distal region.” Contrary to their expectations, that hyperactivity did not enhance function in that area but rather dampened it. Hence: “There is diminished pattern separation and augmented pattern completion,” she said.
– they may recall a certain restaurant they’d been to but not be able to separate what happened during one visit versus another.
Why do some older adults stay sharp?
That memory impairment does not happen to everyone, and it doesn’t happen to all rats either. In fact, the researchers found that some older rats performed spatial-learning tasks as well as young rats did – even though their brains were already beginning to favor pattern completion.
If we can better understand why this happens, we may uncover new therapies for age-related memory loss, Dr. Lee said.
Coauthor Michela Gallagher’s team previously demonstrated that the anti-epilepsy drug levetiracetam improves memory performance by reducing hyperactivity in the hippocampus.
The extra detail this study adds may allow scientists to better aim such drugs in the future, Dr. Lee speculated. “It would give us better control of where we could possibly target the deficits we see.”

Scientists at Johns Hopkins University have identified a mechanism in the brain behind age-related memory loss, expanding our knowledge of the inner workings of the aging brain and possibly opening the door to new Alzheimer’s treatments.
The researchers looked at the hippocampus, a part of the brain thought to store long-term memories.
Neurons there are responsible for a pair of memory functions – called pattern separation and pattern completion – that work together in young, healthy brains. These functions can swing out of balance with age, impacting memory.
The Johns Hopkins team may have discovered what causes this imbalance. Their findings – reported in a paper in the journal Current Biology – may not only help us improve dementia treatments, but even prevent or delay a loss of thinking skills in the first place, the researchers say.

FROM CURRENT BIOLOGY
What is palliative care and what’s new in practicing this type of medicine?
The World Health Organization defines palliative care as “an approach that improves the quality of life of patients (adults and children) and their families who are facing problems associated with life-threatening illness. It prevents and relieves suffering through the early identification, correct assessment, and treatment of pain and other problems, whether physical, psychosocial or spiritual.”1
The common misperception is that palliative care is only for those at end of life or only in the advanced stages of their illness. However, palliative care is ideally most helpful following individuals from diagnosis through their illness trajectory. Another misperception is that palliative care and hospice are the same thing. Though all hospice is palliative care, all palliative care is not hospice. Both palliative care and hospice provide care for individuals facing a serious illness and focus on the same philosophy of care, but palliative care can be initiated at any stage of illness, even if the goal is to pursue curative and life-prolonging therapies/interventions.
In contrast, hospice is considered for those who are at the end of life and are usually not pursuing life-prolonging therapies or interventions, instead focusing on comfort, symptom management, and optimization of quality of life.
Though there is a growing need for palliative care, there is a shortage of specialist palliative care providers. Much of the palliative care needs can be met by all providers who can offer basic symptom management, identification surrounding goals of care and discussions of advance care planning, and understanding of illness/prognosis and treatment options, which is called primary palliative care.2 In fact, two-thirds of patients with a serious illness other than cancer prefer discussion of end-of-life care or advance care planning with their primary care providers.3
Referral to specialty palliative care should be considered when there are more complexities to symptom/pain management and goals of care/end of life, transition to hospice, or complex communication dynamics.4
Though specialty palliative care was shown to be more comprehensive, both primary palliative care and specialty palliative care have led to improvements in the quality of life in individuals living with serious illness.5 Early integration of palliative care into routine care has been shown to improve symptom burden, mood, quality of life, survival, and health care costs.6
Updates in alternative and complementary therapies to palliative care
There are several alternative and complementary therapies to palliative care, including cannabis and psychedelics. These therapies are becoming or may become a familiar part of medical therapies that are listed in a patient’s history as part of their medical regimen, especially as more states continue to legalize and/or decriminalize the use of these alternative therapies for recreational or medicinal use.
Both cannabis and psychedelics have a longstanding history of therapeutic and holistic use. Cannabis has been used to manage symptoms such as pain since the 16th and 17th century.7 In palliative care, more patients may turn to various forms of cannabis as a source of relief from symptoms and suffering as their focus shifts more to quality of life.
Even with the increasing popularity of the use of cannabis among seriously ill patients, there is still a lack of evidence of the benefits of medical cannabis use in palliative care, and there is a lack of standardization of type of cannabis used and state regulations regarding their use.7
A recent systematic review found that despite the reported positive treatment effects of cannabis in palliative care, the results of the studies were conflicting. This highlights the need for further high-quality research to determine whether cannabis products are an effective treatment in palliative care patients.8
One limitation to note is that the majority of the included studies focused on cannabis use in patients with cancer for cancer-related symptoms. Few studies included patients with other serious conditions.
Psychedelics
There is evidence that psychedelic assisted therapy (PAT) is a safe and effective treatment for individuals with refractory depression, posttraumatic stress disorder, and substance use disorder.9 Plus, there have been ample studies providing support that PAT improves symptoms such as refractory anxiety/depression, demoralization, and existential distress in seriously ill patients, thus improving their quality of life and overall well-being.9
Nine U.S. cities and the State of Oregon have decriminalized or legalized the psychedelic psilocybin, based on the medical benefits patients have experienced evidenced from using it.10
In light of the increasing interest in PAT, Dr. Ira Byock provided the following points on what “all clinicians should know as they enter this uncharted territory”:
- Psychedelics have been around for a long time.
- Psychedelic-assisted therapies’ therapeutic effects are experiential.
- There are a variety of terms for specific categories of psychedelic compounds.
- Some palliative care teams are already caring for patients who undergo psychedelic experiences.
- Use of psychedelics should be well-observed by a skilled clinician with expertise.
I am hoping this provides a general refresher on palliative care and an overview of updates to alternative and complementary therapies for patients living with serious illness.9
