Lecanemab (Eisai/Biogen), an investigational amyloid-clearing monoclonal antibody, reduced cognitive decline by 27%, compared with placebo and decreased amyloid levels in the brain of adults enrolled in a phase 3 trial.

The Clarity AD trial included 1,795 adults with early AD and confirmed amyloid pathology in the brain. Treatment consisted of lecanemab 10 mg/kg biweekly or matching placebo.

Treatment with lecanemab met the primary endpoint, reducing clinical decline on the global cognitive and functional scale, the Clinical Dementia Rating–Sum of Boxes (CDR-SB), at 18 months by 27%, compared with placebo, with a treatment difference in the score change of –0.45 (P = .00005), the companies reported.

Starting as early as 6 months, across all time points, treatment with lecanemab yielded highly statistically significant changes in CDR-SB from baseline, compared with placebo (all P < .01).

The study also met all key secondary endpoints with highly statistically significant results, compared with placebo (P < .01).

Key secondary endpoints, in comparison with placebo, were change from baseline at 18 months in amyloid levels in the brain measured by amyloid PET, the AD Assessment Scale–cognitive subscale14 (ADAS-cog14), the AD Composite Score (ADCOMS), and the AD Cooperative Study–Activities of Daily Living Scale for Mild Cognitive Impairment (ADCS MCI-ADL).
 

Imaging abnormalities within expectations

Overall, rates of amyloid-related imaging abnormalities (ARIA) related to lecanemab were “within expectations,” the companies said.

The incidence of ARIA related to edema (ARIA-E) was 12.5% in the lecanemab group and 1.7% in the placebo group.

The incidence of symptomatic ARIA-E was 2.8% and 0.0%, respectively, and the rate of cerebral hemorrhage (ARIA-H) was 17.0% and 8.7%. The total incidence of ARIA (ARIA-E and/or ARIA-H) was 21.3% in the lecanemab group and 9.3% in the placebo group.

Full results of the Clarity AD trial will be presented in November at the Clinical Trials on Alzheimer’s Congress.
 

Incremental benefit

Responding to the findings, the Alzheimer’s Association said in a statement that it “enthusiastically welcomes” the positive findings. It noted that these are “the most encouraging results in clinical trials treating the underlying causes of Alzheimer’s to date.

“For people in the earliest stages of Alzheimer’s, this treatment has the potential to change the course of the disease in a clinically meaningful way. These results indicate lecanemab may give people more time at or near their full abilities to participate in daily life, remain independent and make future health care decisions,” the Alzheimer’s Association added.

Also weighing in, Howard Fillit, MD, cofounder and chief science officer at the Alzheimer’s Drug Discovery Foundation, said in a release that “the combination of the biomarker change – reduced amyloid – plus slowing of cognitive decline in this study is encouraging news for the 57 million patients around the world living with Alzheimer’s.

“However, amyloid-clearing drugs will provide an incremental benefit at best, and there is still a pressing need for the next generation of drugs focused on other targets based on our knowledge of the biology of aging,” Dr. Fillit cautioned.

“We are optimistic about the future as many of these drugs are in development, with 75% of drugs in the pipeline now targeting nonamyloid pathways of neurodegeneration,” he added.

In July 2022, the Food and Drug Administration accepted Eisai’s biologics license application for lecanemab under the accelerated approval pathway and granted priority review. Lecanemab has a prescription Drugs User Fee Act action date of Jan. 6, 2023.

Developmental language disorder (DLD) is characterized by receptive or expressive language difficulties or both. Children with the neurodevelopmental condition “struggle to comprehend and use their native language for no obvious reason,” said the authors of a new study. This leads to problems with grammar, vocabulary, and holding conversations, and in turn an increased risk of “difficulties when learning to read, underachieving academically, being unemployed, and facing social and mental health challenges.”

The condition is common and estimated to affect 7% of children – approximately two in every classroom – but is “underrecognized” said the authors.

Saloni Krishnan, PhD, reader at Royal Holloway, University of London, who led the study as a research fellow at the University of Oxford, England, explained: “DLD is a relatively unknown and understudied condition, unlike better known neurodevelopmental conditions such as ADHD, dyslexia, or autism.”

It is suspected that children with DLD may have differences in areas of the brain involved with learning habits and rules. “Although we know that DLD does not result from gross neural lesions, we still do not have a clear picture of how brain anatomy differs in children with DLD,” the authors highlighted.
 

Language learning difficulties linked to brain differences

For their study, published in eLife, researchers used an MRI technique called multiparameter mapping (MPM) to investigate microstructural neural differences in children with DLD. The technique measures the properties of brain tissue and is particularly useful for measuring the amounts of myelin.

“Understanding the neural basis of DLD is particularly challenging given the developmental nature of the disorder, as well as the lack of animal models for understanding language,” explained the authors. However, they pointed out that MPM allows an “unparalleled in vivo method” to investigate microstructural neural changes in children with DLD.

Kate Watkins, PhD, professor of cognitive neuroscience at the University of Oxford and senior author, said: “This type of scan tells us more about the makeup or composition of the brain tissue in different areas.”

As part of the Oxford Brain Organisation in Language Development (OxBOLD) study, the researchers recruited and tested 175 children between the ages of 10 and 15 years. Subsequently, 56 children with typical language development and 33 children with DLD were scanned using MPM.

The researchers compared the two groups and found that children with DLD have less myelin in parts of the brain responsible for speaking, listening, and learning rules and habits.

Specifically, maps of magnetization transfer saturation (MTsat) – which index myelin – in children with DLD showed reductions in MTsat values in the caudate nucleus bilaterally, and in the left ventral sensorimotor cortex and Heschl’s gyrus.

“Our findings using this protocol suggest that the caudate nucleus, as well as regions in the wider speech and language network, show alterations in myelin in children with DLD,” explained the authors.

“Given myelin’s role in enabling fast and reliable communication in the brain, reduced myelin content may explain why children with DLD struggle with speech and language processing,” they highlighted.
 

Significant advance in DLD understanding

The study findings established changes in striatal and cortical myelin as a “neural basis for DLD,” explained the journal editor, who highlighted that this was a “significant advance” in the understanding of DLD. “These brain differences may explain the poorer language outcomes in this group,” the authors said.

The findings “strongly point” to a role for the striatum in the development of DLD, and this role is likely to be in the “learning of habits and sequences,” the authors said.

They pointed out, however, that myelin patterns can change over development, and that myelination can be observed after successful training. “It is important to assess whether these differences in myelin persist over development in DLD, and if they can be targeted through training using behavioral interventions,” they emphasized.

Professor Watkins commented: “The findings might help us understand the pathways involved at a biological level and ultimately allow us to explain why children with DLD have problems with language learning.”

A spokesperson for the RADLD (Raising Awareness of Developmental Language Disorder) organization, commented: “Developmental language disorder has long been understood to have a neurological basis; however, these differences in the brain development have received limited attention in research.” It added that utilizing new technology helps to better understand the “potential neurological differences” experienced by people with DLD.

More studies are needed to determine if these brain differences cause language problems and how or if experiencing language difficulties could cause these changes in the brain, explained the authors. They hoped that further research may help scientists find new treatments that target these brain differences.

Long COVID is likely to cost the U.S. economy trillions of dollars and will almost certainly affect multiple industries, from restaurants struggling to replace low-wage workers, to airlines scrambling to replace crew, to overwhelmed hospitals, experts are predicting.

“There’s a lot we need to do to understand what it takes to enable disabled people to participate more in the economy,” said Katie Bach, a senior fellow with Brookings Institution and the author of a study looking into long COVID’s impact on the labor market.

Data from June 2022 from the Centers for Disease Control and Prevention shows that, of the 40% of American adults who contracted COVID-19, nearly one in five still have long COVID symptoms. That works out to 1 in 13, or 7.5%, of the overall U.S. adult population.

Drawing from the CDC data, Ms. Bach estimates in her August 2022 report that as many as 4 million working-age Americans are too sick with long COVID to perform their jobs. That works out to as much as $230 billion in lost wages, or almost 1% of the U.S. GDP.

“This is a big deal,” she said. “We’re talking potentially hundreds of billions of dollars a year and that this is big enough to have a measurable impact on the labor market.”

Other sources have suggested lower figures, but the conclusions are the same: Long COVID is an urgent issue that will cost tens of billions of dollars a year in lost wages alone, Ms. Bach said. But it’s not just lost income for workers. There is a cost for businesses and the public.

Throughout the pandemic, COVID-19’s crippling force could be felt across multiple industries. While business has picked up again, staffing shortages remain a challenge. At some airports this summer, air passengers spent hours in security lines; were stranded for days as flights were canceled, rebooked, and canceled again on short notice; and waited weeks for lost luggage. Restaurants have had to cut back their hours. Those seeking medical care had longer than usual wait times in EDs and urgent care clinics. Some EDs temporarily closed.

These challenges have been attributed in part to the “great resignation” and in part because so many infected workers were out, especially during the Omicron waves. But increasingly, economists and health care professionals alike worry about long COVID’s impact on employers and the broader economy.

David Cutler, PhD, a professor of economics at Harvard University, Cambridge, Mass., believes the total economic loss could be as high as $3.7 trillion, when factoring in the lost quality of life, the cost in lost earnings, and the cost of higher spending on medical care. His estimate is more than a trillion dollars higher than a previous projection he and fellow economist Lawrence Summers, PhD, made in 2020. The reason? Long COVID.

“The higher estimate is largely a result of the greater prevalence of long COVID than we had guessed at the time,” Dr. Cutler wrote in a paper released in July.

“There are about 10 times the number of people with long COVID as have died of COVID. Because long COVID is so new, there is uncertainty about all of the numbers involved in the calculations. Still, the costs here are conservative, based on only cases to date.”

In Ms. Bach’s Brookings report, she projected that, if recovery from long COVID does not pick up and the population of Americans with long COVID were to grow by 10% a year, the annual cost of lost wages alone could reach half a trillion dollars in a decade.

Meanwhile, a working paper by the National Bureau of Economic Research found that workers who missed an entire week of work because of probable COVID-19 illnesses were roughly 7 percentage points less likely to be working a year later, compared with those who did not miss work for health reasons.

“It’s not just individuals with long COVID who are suffering from this. It impacts their families, their livelihoods, and the economy on a global scale. So, we have to raise awareness about those ripple effects,” said Linda Geng, MD, a clinical assistant professor of medicine with Stanford (Calif.) University’s Primary Care and Population Health. 

“I think it’s hard for the public to grasp ... and understand the scale of this public health crisis.”
 

Debilitating fatigue

Long COVID is roughly defined; the CDC defines it as symptoms that linger 3 or more months after a patient first catches the virus.

The symptoms vary and include profound fatigue and brain issues.

“It’s a new degree of extreme and debilitating fatigue and exhaustion, to the point where you can’t do your daily tasks,” said Dr. Geng, who is also the codirector of Stanford’s Post-Acute COVID-19 Syndrome Clinic.

“People can be so debilitated, they can’t even do basic things, like the activities of daily living, let alone do their job, particularly if it’s physically or mentally demanding.”

Patients can also have postexertional malaise, where they feel especially bad and symptoms worsen when they exert themselves physically or mentally, Dr. Geng said. Compounding the issue for many long COVID patients is their trouble getting restful sleep. Those with brain fog have issues with memory, processing information, focused concentration, confusion, making mistakes, and multitasking. Pain is another debilitating symptom that can disrupt daily life and ability to work.

Even people with relatively mild infections can end up with long COVID, Dr. Geng said, noting that many of the patients at the Stanford clinic were never hospitalized with their initial infections. While existing research and Dr. Geng’s clinical experience show that long COVID can hit any age, she most commonly sees patients from ages 20 to their 60s, with an average age in the 40s – people in their prime working ages.

Jason Furman, PhD, a former White House economic adviser who is now a professor at Harvard University, noted in August that the labor force participation rate was far below what could be explained by standard demographic changes like an aging population, with the decline evident across all age groups. Dr. Furman does not speculate about why, but others have.

“We are pessimistic: Both the aging of the population and the impact of long COVID imply that the participation rate will be slow to return to its prepandemic level,” Anna Wong, Yelena Shulyatyeva, Andrew Husby, and Eliza Winger, economists with Bloomberg Economics, wrote in a research note. 
 

Supportive policies 

There is some evidence that vaccination reduces the risk of long COVID, but not completely, and it is too early to know if repeat infections increase long COVID risks. There is also no definitive data on how fast or how many people are recovering. Economists often assume that those with long COVID will recover at some point, Ms. Bach noted, but she is careful not to make assumptions.

“If people aren’t recovering, then this group keeps getting bigger,” she said. “We’re still adding, and if people aren’t coming out of that group, this becomes a bigger and bigger problem.”

For now, the number of new people being diagnosed with long COVID appears to have slowed, Ms. Bach said, but it remains to be seen whether the trend can be sustained.

“If people are impaired longer than we think and if the impairment turns out to be severe, then we can have a lot of people who need services like disability insurance,” Dr. Cutler said.

“That could put a really big strain on public sector programs and our ability to meet those needs.”

Policies that support the research and clinical work necessary to prevent and treat long COVID are essential, experts say.

“To me, that is the biggest economic imperative, to say nothing of human suffering,” said Ms. Bach. 

Employers also have a role, and experts say there are a number of accommodations businesses should consider. What happens when an employee has long COVID? Can accommodations be made that allow them to continue working productively? If they spend a great deal of time commuting, can they work from home? What can employers do so that family members do not have to drop out of the workforce to take care of loved ones with long COVID? 
 

Disability insurance

To be sure, there is one piece of the puzzle that does not quite fit, according to Dr. Cutler and Ms. Bach. There is no sign yet of a large increase in federal disability insurance applications, and no one quite knows why. Publicly available government data shows that online applications actually dipped by about 4% each year between 2019 and 2021. Applications in 2022 appear on track to remain slightly below prepandemic levels. 

To qualify for Social Security Disability Insurance (SSDI), people need to have a disability that lasts at least a year. 

“If you’re disabled with long COVID, who knows, right? You don’t know,” said Ms. Bach. “Two of the most dominant symptoms of long COVID are fatigue and brain fog. So, I’ve heard from people that the process of going through an SSDI application is really hard.”

Some long COVID patients told Ms. Bach they simply assumed they would not get SSDI and did not even bother applying. She stressed that working Americans with debilitating long COVID should be aware that their condition is protected by the Americans with Disabilities Act. But the challenge, based on guidance issued by the government, is that not all cases of long COVID qualify as a disability and that individual assessments are necessary.

While more long COVID data are needed, Ms. Bach believes there is enough information for decisionmakers to go after the issue more aggressively. She pointed to the $1.15 billion in funding that Congress earmarked for the National Institutes of Health over the course of 4 years in support of research into the long-term health effects of COVID-19.

“Now, $250 million a year sounds like a lot of money until you start talking about the cost of lost wages – just lost wages,” Ms. Bach said. “That’s not lost productivity. That’s not the cost of people whose family members are sick. Who have to reduce their own labor force participation. That’s not medical costs. Suddenly, $250 million doesn’t really sound like that much.”

Data from June 2022 from the Centers for Disease Control and Prevention shows that, of the 40% of American adults who contracted COVID-19, nearly one in five still have long COVID symptoms. That works out to 1 in 13, or 7.5%, of the overall U.S. adult population.

Drawing from the CDC data, Ms. Bach estimates in her August 2022 report that as many as 4 million working-age Americans are too sick with long COVID to perform their jobs. That works out to as much as $230 billion in lost wages, or almost 1% of the U.S. GDP.

“This is a big deal,” she said. “We’re talking potentially hundreds of billions of dollars a year and that this is big enough to have a measurable impact on the labor market.”

Other sources have suggested lower figures, but the conclusions are the same: Long COVID is an urgent issue that will cost tens of billions of dollars a year in lost wages alone, Ms. Bach said. But it’s not just lost income for workers. There is a cost for businesses and the public.

Throughout the pandemic, COVID-19’s crippling force could be felt across multiple industries. While business has picked up again, staffing shortages remain a challenge. At some airports this summer, air passengers spent hours in security lines; were stranded for days as flights were canceled, rebooked, and canceled again on short notice; and waited weeks for lost luggage. Restaurants have had to cut back their hours. Those seeking medical care had longer than usual wait times in EDs and urgent care clinics. Some EDs temporarily closed.

These challenges have been attributed in part to the “great resignation” and in part because so many infected workers were out, especially during the Omicron waves. But increasingly, economists and health care professionals alike worry about long COVID’s impact on employers and the broader economy.

David Cutler, PhD, a professor of economics at Harvard University, Cambridge, Mass., believes the total economic loss could be as high as $3.7 trillion, when factoring in the lost quality of life, the cost in lost earnings, and the cost of higher spending on medical care. His estimate is more than a trillion dollars higher than a previous projection he and fellow economist Lawrence Summers, PhD, made in 2020. The reason? Long COVID.

“The higher estimate is largely a result of the greater prevalence of long COVID than we had guessed at the time,” Dr. Cutler wrote in a paper released in July.

“There are about 10 times the number of people with long COVID as have died of COVID. Because long COVID is so new, there is uncertainty about all of the numbers involved in the calculations. Still, the costs here are conservative, based on only cases to date.”

In Ms. Bach’s Brookings report, she projected that, if recovery from long COVID does not pick up and the population of Americans with long COVID were to grow by 10% a year, the annual cost of lost wages alone could reach half a trillion dollars in a decade.

Meanwhile, a working paper by the National Bureau of Economic Research found that workers who missed an entire week of work because of probable COVID-19 illnesses were roughly 7 percentage points less likely to be working a year later, compared with those who did not miss work for health reasons.

“It’s not just individuals with long COVID who are suffering from this. It impacts their families, their livelihoods, and the economy on a global scale. So, we have to raise awareness about those ripple effects,” said Linda Geng, MD, a clinical assistant professor of medicine with Stanford (Calif.) University’s Primary Care and Population Health. 

“I think it’s hard for the public to grasp ... and understand the scale of this public health crisis.”
 

Debilitating fatigue

Long COVID is roughly defined; the CDC defines it as symptoms that linger 3 or more months after a patient first catches the virus.

The symptoms vary and include profound fatigue and brain issues.

“It’s a new degree of extreme and debilitating fatigue and exhaustion, to the point where you can’t do your daily tasks,” said Dr. Geng, who is also the codirector of Stanford’s Post-Acute COVID-19 Syndrome Clinic.

“People can be so debilitated, they can’t even do basic things, like the activities of daily living, let alone do their job, particularly if it’s physically or mentally demanding.”

Patients can also have postexertional malaise, where they feel especially bad and symptoms worsen when they exert themselves physically or mentally, Dr. Geng said. Compounding the issue for many long COVID patients is their trouble getting restful sleep. Those with brain fog have issues with memory, processing information, focused concentration, confusion, making mistakes, and multitasking. Pain is another debilitating symptom that can disrupt daily life and ability to work.

Even people with relatively mild infections can end up with long COVID, Dr. Geng said, noting that many of the patients at the Stanford clinic were never hospitalized with their initial infections. While existing research and Dr. Geng’s clinical experience show that long COVID can hit any age, she most commonly sees patients from ages 20 to their 60s, with an average age in the 40s – people in their prime working ages.

Jason Furman, PhD, a former White House economic adviser who is now a professor at Harvard University, noted in August that the labor force participation rate was far below what could be explained by standard demographic changes like an aging population, with the decline evident across all age groups. Dr. Furman does not speculate about why, but others have.

“We are pessimistic: Both the aging of the population and the impact of long COVID imply that the participation rate will be slow to return to its prepandemic level,” Anna Wong, Yelena Shulyatyeva, Andrew Husby, and Eliza Winger, economists with Bloomberg Economics, wrote in a research note. 
 

Supportive policies 

There is some evidence that vaccination reduces the risk of long COVID, but not completely, and it is too early to know if repeat infections increase long COVID risks. There is also no definitive data on how fast or how many people are recovering. Economists often assume that those with long COVID will recover at some point, Ms. Bach noted, but she is careful not to make assumptions.

“If people aren’t recovering, then this group keeps getting bigger,” she said. “We’re still adding, and if people aren’t coming out of that group, this becomes a bigger and bigger problem.”

For now, the number of new people being diagnosed with long COVID appears to have slowed, Ms. Bach said, but it remains to be seen whether the trend can be sustained.

“If people are impaired longer than we think and if the impairment turns out to be severe, then we can have a lot of people who need services like disability insurance,” Dr. Cutler said.

“That could put a really big strain on public sector programs and our ability to meet those needs.”

Policies that support the research and clinical work necessary to prevent and treat long COVID are essential, experts say.

“To me, that is the biggest economic imperative, to say nothing of human suffering,” said Ms. Bach. 

Employers also have a role, and experts say there are a number of accommodations businesses should consider. What happens when an employee has long COVID? Can accommodations be made that allow them to continue working productively? If they spend a great deal of time commuting, can they work from home? What can employers do so that family members do not have to drop out of the workforce to take care of loved ones with long COVID? 
 

Disability insurance

To be sure, there is one piece of the puzzle that does not quite fit, according to Dr. Cutler and Ms. Bach. There is no sign yet of a large increase in federal disability insurance applications, and no one quite knows why. Publicly available government data shows that online applications actually dipped by about 4% each year between 2019 and 2021. Applications in 2022 appear on track to remain slightly below prepandemic levels. 

To qualify for Social Security Disability Insurance (SSDI), people need to have a disability that lasts at least a year. 

“If you’re disabled with long COVID, who knows, right? You don’t know,” said Ms. Bach. “Two of the most dominant symptoms of long COVID are fatigue and brain fog. So, I’ve heard from people that the process of going through an SSDI application is really hard.”

Some long COVID patients told Ms. Bach they simply assumed they would not get SSDI and did not even bother applying. She stressed that working Americans with debilitating long COVID should be aware that their condition is protected by the Americans with Disabilities Act. But the challenge, based on guidance issued by the government, is that not all cases of long COVID qualify as a disability and that individual assessments are necessary.

While more long COVID data are needed, Ms. Bach believes there is enough information for decisionmakers to go after the issue more aggressively. She pointed to the $1.15 billion in funding that Congress earmarked for the National Institutes of Health over the course of 4 years in support of research into the long-term health effects of COVID-19.

“Now, $250 million a year sounds like a lot of money until you start talking about the cost of lost wages – just lost wages,” Ms. Bach said. “That’s not lost productivity. That’s not the cost of people whose family members are sick. Who have to reduce their own labor force participation. That’s not medical costs. Suddenly, $250 million doesn’t really sound like that much.”

Herpes to the rescue

Let’s face it: When people hear the word “herpes,” their first thoughts are not positive. But what if herpes could be a hero?

Scientists have found a way to make a strain of herpes that kills cancer because, hey, it’s 2022, and anything is possible. Trials have been going well and this seems like a safe and effective way to fight cancer.

Aunt_Spray/Thinkstock

Viruses may be one of our oldest enemies, but it’s also been said that the enemy of my enemy is my friend. So why not make herpes the enemy of cancer, thereby turning it into our friend? The genetically modified herpes virus is injected directly into tumors, where it destroys cancer cells from within. But wait, there’s more! The patient’s immune system also senses the virus and springs into action against it and the cancer in which it is residing.

During the phase 1 trial, three of the nine patients saw tumor reduction and the therapy proved safe as well. Future trials will be able to more specifically target various cancer types and make the treatment better. For once, we are rooting for you, herpes.
 

A breath of not-so-fresh air

There’s nothing quite like that first real warm day of spring. You can finally open the windows and clear out the old stuffy air that’s been hanging around all winter long. It’s a ritual that’s now backed up with some science in the form of a new study. Turns out that there’s actually a fair amount of smog in the average home. That’s right, smog’s not just for the big city anymore.

PxHere

As part of the HOMEChem project, a whole host of scientists gathered together under one roof in a typical suburban house and immediately started doing chores. Cooking, cleaning, the works. No, it wasn’t because they had trashed the place the night before. They had set up instrumentation all around the house to measure the chemical makeup of the air inside. A scientist’s idea of a wild party.

The results are perhaps not all that surprising, but interesting nonetheless. Your homemade smog certainly won’t kill you, but there’s both an increased amount and higher concentration of airborne toxins in indoor air, compared with outdoors. Benzene and formaldehyde were common, as were acrolein (a pulmonary toxicant emitted by lumber and burning fats) and isocyanic acid (which can react with proteins in the human body). The researchers noted that most of these chemicals can be removed with proper ventilation.

Although cleaning is certainly responsible for a fair share of the chemicals, cooking generally produced more toxic compounds, similar to what’s found in wildfire smoke. One of the researchers said this makes sense, since a wildfire can be considered an “extreme form of cooking.” Scientists may not know how to party, but their idea of a barbecue sounds … interesting. We’re looking forward to an upcoming study out of California: Can a 1-million acre wildfire adequately cook a ribeye steak?
 

We’re dying to try composting ... with humans, that is

We here at LOTME are not really fans of politicians, except as objects of ridicule. That is kind of fun. Whether we’re watching Fox News, listening to NPR, or reading Vladimir Putin’s fashion blog, one thing remains clear: If you want actual information, don’t ask a politician.

There are, of course, always exceptions, and we just found one: California state representative Cristina Garcia. Rep. Garcia sponsored a bill just signed into law by Gov. Gavin Newsom that legalizes the practice of human composting, the reduction of remains by “placing bodies in individual vessels and fostering gentle transformation into a nutrient-dense soil.”

Since we’ve written about this sort of thing before – Washington was the first state to legalize the process back in 2019 – we’re more interested now in what Rep. Garcia told NBC News while describing her motivation: “I’ve always wanted to be a tree. The idea of having my family sitting under my shade one day – that brings a lot of joy.” How great is that? Tree-hugging is just not enough. Be the tree.

California is the fifth state to provide its residents with the human composting option, the other three being Colorado, Oregon, and Vermont. The process “typically involves putting a body into a steel vessel, then covering it with organic materials like straw, wood chips and alfalfa. Microbes break down the corpse and the plant matter, transforming the various components into nutrient-rich soil in roughly 30 days,” Smithsonian Magazine explained.

We just happen to have some good news for Rep. Garcia about that wanting-to-be-a-tree business. She’s already pretty close. For more on that, we go to our correspondent from beyond the grave, Carl Sagan, who shares a thought about trees. And no, we couldn’t just write out his quote here. You have to hear it in Dr. Sagan’s own voice.
 

That’ll be one pandemic with extra distress. Hold the goals

When the COVID-19 pandemic first hit it put a lot of stuff on hold for everyone. Couldn’t eat inside at your favorite restaurant, attend that long-awaited concert, or travel out of the country. Those were all pretty bad, but it was the disruption of pursuing long-term goals that seemed to have the most effect on people’s mental health.

Investigators from the University of Waterloo (Ont.) looked at how putting such goals on hold affected people’s mental well-being. The study’s 226 participants were asked about their “COVID-frozen” goals and the degree to which they were able to actively pursue each goal and how committed they were to achieving it.

What they found was that the participants’ COVID-frozen goals were associated with feelings of psychological distress, such as anxiety, depressive symptoms, stress, and lowered life satisfaction. It was only when participants were able to disengage from goal rumination that well-being was impacted positively.

“Goal rumination is compulsive and can aggravate worries and frustrations while also taking away mental resources from other goals,” Candice Hubley, lead author and a PhD candidate in psychology, said in a written statement. So in short, you’re only stressing yourself out more about something that is far off in the distance when you could be focusing more on short-term, tangible goals instead.

Now, no one is saying to give up on your goals. Just take them one at a time. You’ll have better life satisfaction and your COVID-frozen goals will thaw out before you know it.

We’re dying to try composting ... with humans, that is

We here at LOTME are not really fans of politicians, except as objects of ridicule. That is kind of fun. Whether we’re watching Fox News, listening to NPR, or reading Vladimir Putin’s fashion blog, one thing remains clear: If you want actual information, don’t ask a politician.

Recompose

There are, of course, always exceptions, and we just found one: California state representative Cristina Garcia. Rep. Garcia sponsored a bill just signed into law by Gov. Gavin Newsom that legalizes the practice of human composting, the reduction of remains by “placing bodies in individual vessels and fostering gentle transformation into a nutrient-dense soil.”

Since we’ve written about this sort of thing before – Washington was the first state to legalize the process back in 2019 – we’re more interested now in what Rep. Garcia told NBC News while describing her motivation: “I’ve always wanted to be a tree. The idea of having my family sitting under my shade one day – that brings a lot of joy.” How great is that? Tree-hugging is just not enough. Be the tree.

California is the fifth state to provide its residents with the human composting option, the other three being Colorado, Oregon, and Vermont. The process “typically involves putting a body into a steel vessel, then covering it with organic materials like straw, wood chips and alfalfa. Microbes break down the corpse and the plant matter, transforming the various components into nutrient-rich soil in roughly 30 days,” Smithsonian Magazine explained.

We just happen to have some good news for Rep. Garcia about that wanting-to-be-a-tree business. She’s already pretty close. For more on that, we go to our correspondent from beyond the grave, Carl Sagan, who shares a thought about trees. And no, we couldn’t just write out his quote here. You have to hear it in Dr. Sagan’s own voice.
 

That’ll be one pandemic with extra distress. Hold the goals

When the COVID-19 pandemic first hit it put a lot of stuff on hold for everyone. Couldn’t eat inside at your favorite restaurant, attend that long-awaited concert, or travel out of the country. Those were all pretty bad, but it was the disruption of pursuing long-term goals that seemed to have the most effect on people’s mental health.

Investigators from the University of Waterloo (Ont.) looked at how putting such goals on hold affected people’s mental well-being. The study’s 226 participants were asked about their “COVID-frozen” goals and the degree to which they were able to actively pursue each goal and how committed they were to achieving it.

What they found was that the participants’ COVID-frozen goals were associated with feelings of psychological distress, such as anxiety, depressive symptoms, stress, and lowered life satisfaction. It was only when participants were able to disengage from goal rumination that well-being was impacted positively.

“Goal rumination is compulsive and can aggravate worries and frustrations while also taking away mental resources from other goals,” Candice Hubley, lead author and a PhD candidate in psychology, said in a written statement. So in short, you’re only stressing yourself out more about something that is far off in the distance when you could be focusing more on short-term, tangible goals instead.

Now, no one is saying to give up on your goals. Just take them one at a time. You’ll have better life satisfaction and your COVID-frozen goals will thaw out before you know it.

About 5% of traditional Medicare patients who had telehealth visits were seen virtually by out-of-state clinicians in the first half of 2021, according to a new study in JAMA Health Forum.

Since then, however, many states have restored restrictions that prevent physicians who are licensed in one state from having telehealth visits with patients unless they’re licensed in the state where the patients live.

This is not fair to many people who live in areas near state borders, the authors argued. For those patients, it is much more convenient to see their primary care physician in a virtual visit from home than to travel to the doctor’s office in another state. This convenience is enjoyed by most patients who reside elsewhere in their state because they’re seeing physicians who are licensed there.

Moreover, the paper said, patients who live in rural areas and in counties with relatively few physicians per capita would also benefit from relaxed telemedicine restrictions.

Using Medicare claims data, the researchers examined the characteristics of out-of-state (OOS) telemedicine visits for the 6 months from January to June 2021. They chose that period for two reasons: by then, health care had stabilized after the chaotic early phase of the pandemic, and in most states, the relaxation of licensing rules for OOS telehealth had not yet lapsed. Earlier periods of time were also used for certain types of comparisons.

Among fee-for-service Medicare beneficiaries, the number of OOS telemedicine visits peaked at 451,086 in April 2020 and slowly fell to 175,545 in June 2021, according to the study. The fraction of OOS telehealth visits among all virtual visits was 4.5% in April 2020 and increased to 5.6% by June 2021.
 

Staying close to home

Of all beneficiaries with a telemedicine visit in the study period, 33% lived within 15 miles of a state border. That cohort accounted for 57.2% of all OOS telemedicine visits.

The highest rates of OOS telehealth visits were seen in the District of Columbia (38.5%), Wyoming (25.6%), and North Dakota (21.1%). California (1%), Texas (2%), and Massachusetts (2.1%) had the lowest rates.

Though intuitive in retrospect, the correlation of OOS telemedicine use with proximity to state borders was one of the study’s most important findings, lead author Ateev Mehrotra, MD, a professor at Harvard Medical School, Boston, said in an interview. “It makes sense,” he said. “If you’re in D.C. and you need a cardiologist, you don’t think: ‘I’ll stay in D.C.’ No, Maryland is right there, so you might use a Maryland cardiologist. Now you’re out of state, even though that office might be only half a mile away from you.”

Similar dynamics, he noted, are seen in many metropolitan areas that border on other states, such as Cincinnati; Philadelphia; and Portland, Ore.

This finding lines up with another result of the study: The majority of patients who had OOS telemedicine visits had previously seen in person the doctor who conducted the virtual visit.

Across all OOS telemedicine visits in the first half of 2021, the researchers observed a prior in-person visit between March 2019 and the date of the virtual visit with the same patient and the same clinician in 62.8% of those visits. Across all in-state telehealth visits, 75.8% of them were made by patients who had seen the same clinician in person since March 2019. This preponderance of virtual visits to clinicians whom the patients had already seen in person reflects the fact that, during the pandemic, most physicians began conducting telehealth visits with their own patients, Dr. Mehrotra said.

It also lays to rest the concern that some states have had about allowing OOS telemedicine visits to physicians not licensed in those states, he added. “They think that all these docs from far away are going to start taking care of patients they don’t even know. But our study shows that isn’t the case. Most of the time, doctors are seeing a patient who’s switching over from in-person visits to out-of-state telemedicine.”
 

More specialty care sought

The dominant conditions that patients presented with were the same in OOS telemedicine and within-state virtual visits. However, the use of OOS telemedicine was higher for some types of specialized care.

For example, the rate of OOS telemedicine use, compared with all telemedicine use, was highest for cancer care (9.8%). Drilling down to more specific conditions, the top three in OOS telemedicine visits were assessment of organ transplant (13%); male reproductive cancers, such as prostate cancer (11.3%); and graft-related issues (10.2%).

The specialty trend was also evident in the types of OOS clinicians from whom Medicare patients sought virtual care. The rates of OOS telemedicine use as a percentage of all telemedicine use in particular specialties were highest for uncommon specialties, such as hematology/oncology, rheumatology, urology, medical oncology, and orthopedic surgery (8.5%). There was less use of OOS telemedicine as a percentage of all telemedicine among more common medical specialties (6.4%), mental health specialties (4.4%), and primary care (4.4%).

Despite its relatively low showing in this category, however, behavioral health was the leading condition treated in both within-state and OOS telemedicine visits, accounting for 30.7% and 25.8%, respectively, of those encounters.

States backslide on OOS telehealth

Since the end of the study period, over half of the states have restored some or all of the restrictions on OOS telemedicine that they had lifted during the pandemic.

According to Dr. Mehrotra, 22 states have some kind of regulation in place to allow an OOS clinician to conduct telehealth visits without being licensed in the state. This varies all the way from complete reciprocity with other states’ licenses to “emergency” telemedicine licenses. The other 28 states and Washington, D.C., require an OOS telemedicine practitioner to get a state license.

Various proposals have been floated to ameliorate this situation, the JAMA paper noted. These proposals include an expansion of the Interstate Medical Licensure Compact that the Federation of State Medical Boards organized in 2014. Since the pact became effective in 2014, at least 35 states and the District of Columbia have joined it. Those states have made it simpler for physicians to gain licensure in states other than their original state of licensure. However, Mehrotra said, it’s still not easy, and not many physicians have taken advantage of it.

One new wrinkle has emerged in this policy debate as a result of the Supreme Court decision overturning Roe v. Wade, he noted. Because people are using OOS telemedicine visits to get prescriptions to abort their fetuses, “that has changed the enthusiasm level for it among many states,” he said.

Dr. Mehrotra reported personal fees from the Pew Charitable Trust, Sanofi Pasteur, and Black Opal Ventures outside the submitted work. One coauthor reported receiving grants from Patient-Centered Outcomes Research, National Institute on Aging, Roundtrip, Independence Blue Cross; personal fees or salary from RAND Corporation from Verily Life Sciences; and that the American Telemedicine Association covered a conference fee. No other disclosures were reported.

Drinking two to three daily cups of – ground, instant, or decaffeinated – is associated with significant reductions in new cardiovascular disease (CVD) and mortality risk, compared with avoiding coffee, a new analysis of the prospective UK Biobank suggests.

Ground and instant coffee, but not decaffeinated coffee, also was associated with reduced risk of new-onset arrhythmia, including atrial fibrillation.

“Our study is the first to look at differences in coffee subtypes to tease out important differences which may explain some of the mechanisms through which coffee works,” Peter M. Kistler, MD, of the Alfred Hospital and Baker Heart and Diabetes Institute, Melbourne, Australia, told this news organization.

“Daily coffee intake should not be discouraged by physicians but rather considered part of a healthy diet,” Dr. Kistler said.

“This study supports that coffee is safe and even potentially beneficial, which is consistent with most of the prior evidence,” Carl “Chip” Lavie, MD, who wasn’t involved in the study, told this news organization.

“We do not prescribe coffee to patients, but for the majority who like coffee, they can be encouraged it is fine to take a few cups daily,” said Dr. Lavie, with the Ochsner Heart and Vascular Institute in New Orleans.

The study was published online in the European Journal of Preventive Cardiology.

 

Clear cardiovascular benefits

A total of 449,563 UK Biobank participants (median age 58 years; 55% women), who were free of arrhythmias or other CVD at baseline, reported in questionnaires their level of daily coffee intake and preferred type of coffee.

During more than 12.5 years of follow-up, 27,809 participants (6.2%) died.

Drinking one to five cups per day of ground or instant coffee (but not decaffeinated coffee) was associated with a significant reduction in incident arrhythmia. The lowest risk was with four to five cups per day for ground coffee (hazard ratio [HR] 0.83; 95% confidence interval [CI], 0.76-0.91; P < .0001) and two to three cups per day for instant coffee (HR, 0.88; 95% CI, 0.85-0.92; P < .0001).

Habitual coffee drinking of up to five cups perday was also associated with significant reductions in the risk of incident CVD, when compared with nondrinkers.

Significant reductions in the risk of incident coronary heart disease (CHD) were associated with habitual coffee intake of up to five cups per day, with the lowest risk for CHD observed in those who consumed two to three cups per day (HR 0.89; 95% CI, 0.86-0.91; P < .0001).

Coffee consumption at all levels was linked to significant reduction in the risk of congestive cardiac failure (CCF) and ischemic stroke. The lowest risks were observed in those who consumed two to three cups per day, with HR, 0.83 (95% CI, 0.79-0.87; P < .0001) for CCF and HR, 0.84 (95% CI, 0.78-0.90; P < .0001) for ischemic stroke.

Death from any cause was significantly reduced for all coffee subtypes, with the greatest risk reduction seen with two to three cups per day for decaffeinated (HR, 0.86; 95% CI, 0.81-0.91; P < .0001); ground (HR, 0.73; 95% CI, 0.69-0.78; P < .0001); and instant coffee (HR, 0.89; 95% CI, 0.86-0.93; P < .0001).

“Coffee consumption is associated with cardiovascular benefits and should not empirically be discontinued in those with underlying heart rhythm disorders or cardiovascular disease,” Dr. Kistler told this news organization.

Plausible mechanisms

There are a number of proposed mechanisms to explain the benefits of coffee on CVD.

“Caffeine has antiarrhythmic properties through adenosine A1 and A2A receptor inhibition, hence the difference in effects of decaf vs. full-strength coffee on heart rhythm disorders,” Dr. Kistler explained.

Coffee has vasodilatory effects and coffee also contains antioxidant polyphenols, which reduce oxidative stress and modulate metabolism.

“The explanation for improved survival with habitual coffee consumption remains unclear,” Dr. Kistler said.

“Putative mechanisms include improved endothelial function, circulating antioxidants, improved insulin sensitivity, and reduced inflammation. Another potential mechanism includes the beneficial effects of coffee on metabolic syndrome,” he said.

“Caffeine has a role in weight loss through inhibition of gut fatty acid absorption and increase in basal metabolic rate. Furthermore, coffee has been associated with a significantly lower incidence of type 2 diabetes mellitus,” Dr. Kistler added.
 

Direction of relationship unclear

Charlotte Mills, PhD, University of Reading, England, said this study “adds to the body of evidence from observational trials associating moderate coffee consumption with cardioprotection, which looks promising.”

However, with the observational design, it’s unclear “which direction the relationship goes – for example, does coffee make you healthy or do inherently healthier people consume coffee? Randomized controlled trials are needed to fully understand the relationship between coffee and health before recommendations can be made,” Dr. Mills told the UK nonprofit Science Media Centre.

Annette Creedon, PhD, nutrition scientist with the British Nutrition Foundation, said it’s possible that respondents over- or underestimated the amount of coffee that they were consuming at the start of the study when they self-reported their intake.

“It is therefore difficult to determine whether the outcomes can be directly associated with the behaviors in coffee consumption reported at the start of the study,” she told the Science Media Centre.

The study had no funding. Dr. Kistler has received funding from Abbott Medical for consultancy and speaking engagements and fellowship support from Biosense Webster. Dr. Lavie has no relevant disclosures. Dr. Mills has worked in collaboration with Nestle on research relating to coffee and health funded by UKRI. Dr. Creedon has reported no relevant financial relationships.

Coffee consumption at all levels was linked to significant reduction in the risk of congestive cardiac failure (CCF) and ischemic stroke. The lowest risks were observed in those who consumed two to three cups per day, with HR, 0.83 (95% CI, 0.79-0.87; P < .0001) for CCF and HR, 0.84 (95% CI, 0.78-0.90; P < .0001) for ischemic stroke.

Death from any cause was significantly reduced for all coffee subtypes, with the greatest risk reduction seen with two to three cups per day for decaffeinated (HR, 0.86; 95% CI, 0.81-0.91; P < .0001); ground (HR, 0.73; 95% CI, 0.69-0.78; P < .0001); and instant coffee (HR, 0.89; 95% CI, 0.86-0.93; P < .0001).

“Coffee consumption is associated with cardiovascular benefits and should not empirically be discontinued in those with underlying heart rhythm disorders or cardiovascular disease,” Dr. Kistler told this news organization.

Plausible mechanisms

There are a number of proposed mechanisms to explain the benefits of coffee on CVD.

“Caffeine has antiarrhythmic properties through adenosine A1 and A2A receptor inhibition, hence the difference in effects of decaf vs. full-strength coffee on heart rhythm disorders,” Dr. Kistler explained.

Coffee has vasodilatory effects and coffee also contains antioxidant polyphenols, which reduce oxidative stress and modulate metabolism.

“The explanation for improved survival with habitual coffee consumption remains unclear,” Dr. Kistler said.

“Putative mechanisms include improved endothelial function, circulating antioxidants, improved insulin sensitivity, and reduced inflammation. Another potential mechanism includes the beneficial effects of coffee on metabolic syndrome,” he said.

“Caffeine has a role in weight loss through inhibition of gut fatty acid absorption and increase in basal metabolic rate. Furthermore, coffee has been associated with a significantly lower incidence of type 2 diabetes mellitus,” Dr. Kistler added.
 

Direction of relationship unclear

Charlotte Mills, PhD, University of Reading, England, said this study “adds to the body of evidence from observational trials associating moderate coffee consumption with cardioprotection, which looks promising.”

However, with the observational design, it’s unclear “which direction the relationship goes – for example, does coffee make you healthy or do inherently healthier people consume coffee? Randomized controlled trials are needed to fully understand the relationship between coffee and health before recommendations can be made,” Dr. Mills told the UK nonprofit Science Media Centre.

Annette Creedon, PhD, nutrition scientist with the British Nutrition Foundation, said it’s possible that respondents over- or underestimated the amount of coffee that they were consuming at the start of the study when they self-reported their intake.

“It is therefore difficult to determine whether the outcomes can be directly associated with the behaviors in coffee consumption reported at the start of the study,” she told the Science Media Centre.

The study had no funding. Dr. Kistler has received funding from Abbott Medical for consultancy and speaking engagements and fellowship support from Biosense Webster. Dr. Lavie has no relevant disclosures. Dr. Mills has worked in collaboration with Nestle on research relating to coffee and health funded by UKRI. Dr. Creedon has reported no relevant financial relationships.

Drinking two to three daily cups of – ground, instant, or decaffeinated – is associated with significant reductions in new cardiovascular disease (CVD) and mortality risk, compared with avoiding coffee, a new analysis of the prospective UK Biobank suggests.

Ground and instant coffee, but not decaffeinated coffee, also was associated with reduced risk of new-onset arrhythmia, including atrial fibrillation.

“Our study is the first to look at differences in coffee subtypes to tease out important differences which may explain some of the mechanisms through which coffee works,” Peter M. Kistler, MD, of the Alfred Hospital and Baker Heart and Diabetes Institute, Melbourne, Australia, told this news organization.

“Daily coffee intake should not be discouraged by physicians but rather considered part of a healthy diet,” Dr. Kistler said.

“This study supports that coffee is safe and even potentially beneficial, which is consistent with most of the prior evidence,” Carl “Chip” Lavie, MD, who wasn’t involved in the study, told this news organization.

“We do not prescribe coffee to patients, but for the majority who like coffee, they can be encouraged it is fine to take a few cups daily,” said Dr. Lavie, with the Ochsner Heart and Vascular Institute in New Orleans.

The study was published online in the European Journal of Preventive Cardiology.

 

Clear cardiovascular benefits

A total of 449,563 UK Biobank participants (median age 58 years; 55% women), who were free of arrhythmias or other CVD at baseline, reported in questionnaires their level of daily coffee intake and preferred type of coffee.

During more than 12.5 years of follow-up, 27,809 participants (6.2%) died.

Drinking one to five cups per day of ground or instant coffee (but not decaffeinated coffee) was associated with a significant reduction in incident arrhythmia. The lowest risk was with four to five cups per day for ground coffee (hazard ratio [HR] 0.83; 95% confidence interval [CI], 0.76-0.91; P < .0001) and two to three cups per day for instant coffee (HR, 0.88; 95% CI, 0.85-0.92; P < .0001).

Habitual coffee drinking of up to five cups perday was also associated with significant reductions in the risk of incident CVD, when compared with nondrinkers.

Significant reductions in the risk of incident coronary heart disease (CHD) were associated with habitual coffee intake of up to five cups per day, with the lowest risk for CHD observed in those who consumed two to three cups per day (HR 0.89; 95% CI, 0.86-0.91; P < .0001).

Coffee consumption at all levels was linked to significant reduction in the risk of congestive cardiac failure (CCF) and ischemic stroke. The lowest risks were observed in those who consumed two to three cups per day, with HR, 0.83 (95% CI, 0.79-0.87; P < .0001) for CCF and HR, 0.84 (95% CI, 0.78-0.90; P < .0001) for ischemic stroke.

Death from any cause was significantly reduced for all coffee subtypes, with the greatest risk reduction seen with two to three cups per day for decaffeinated (HR, 0.86; 95% CI, 0.81-0.91; P < .0001); ground (HR, 0.73; 95% CI, 0.69-0.78; P < .0001); and instant coffee (HR, 0.89; 95% CI, 0.86-0.93; P < .0001).

Nightmares in healthy middle-aged and older adults may be an independent risk factor for cognitive decline and dementia, particularly in men, new research suggests.

Results from a large cohort study showed that healthy middle-aged adults who had bad dreams at least once a week were four times more likely to experience cognitive decline over the following decade, and older adults were twice as likely to be diagnosed with dementia, compared with peers who never had bad dreams.

Frequent nightmares may “identify people who are at high risk of developing dementia in the future, several years or decades before the characteristic memory and thinking problems emerge,” study investigator Abidemi Otaiku, BMBS, University of Birmingham, England, said in an interview.

“This would be the optimum time for doctors to intervene to try and slow down or prevent dementia from developing,” Dr. Otaiku said.

The findings were published online in The Lancet journal eClinicalMedicine).
 

Distressing dreams

Distressing dreams have been previously associated with faster cognitive decline and increased dementia risk in patients with Parkinson’s disease (PD), but whether the same holds for individuals from the general population without PD is unknown.

To investigate, Dr. Otaiku examined data from three community-based cohorts in the United States. This included 605 middle-aged adults (aged 35-64 years) who were followed for up to 13 years and 2,600 adults aged 79 and older who were followed for up to 7 years. All were considered cognitively normal at baseline.

The prevalence of frequent distressing dreams, defined as occurring “once a week or more,” was higher in the older cohort compared with the middle-aged cohort (6.9% vs. 6.0%, respectively).

This is in line with other research that showed distressing dreams remain relatively stable throughout early adulthood and then progressively increase in prevalence from middle to older adulthood. 

After adjustment for all covariates, a higher frequency of distressing dreams was linearly and statistically significantly associated with a higher risk for cognitive decline in middle-aged adults (P = .016) and a higher risk for dementia in older adults (P = .001).

In the fully adjusted model, compared with middle-aged adults who never had bad dreams, those who reported having one or more bad dreams weekly had a fourfold risk for cognitive decline (adjusted odds ratio [aOR], 3.99; 95% confidence interval [CI], 1.07-14.85).

Older adults who had one or more bad dreams weekly had a greater than twofold increased risk for developing dementia (aOR, 2.21; 95% CI, 1.35-3.62).
 

Early days

In sex-stratified analyses, distressing dreams were strongly and statistically significantly associated with cognitive decline and dementia in men, but were only weakly and nonsignificantly associated with cognitive decline and dementia in women.

Dr. Otaiku said he suspects some individuals in the preclinical phase of dementia have “subtle neurodegeneration occurring over time in the right frontal lobe: the area of the brain that helps to downregulate negative emotions whilst we are awake, and also whilst we are dreaming.”

This could result in “depression and anxiety in the day, and nightmares and bad dreams during the night,” he said.

It is possible that treatment for frequent nightmares may help to slow cognitive decline and delay or prevent dementia, Dr. Otaiku added.

He noted that prazosin is used to treat nightmares and has been shown to prevent memory decline and reduce amyloid B generation in preclinical studies of Alzheimer’s disease.

“This is an exciting prospect [but] it is still early days and we will need research to see whether treating nightmares might help to reduce dementia risk down the line,” Dr. Otaiku said.
 

Credible research

In an interview regarding these findings, Maria C. Carrillo, PhD, chief science officer for the Alzheimer’s Association, said: “This is credible research consistent with the idea that sleep disturbances may be a risk factor or warning sign of cognitive decline.”

She added that “what’s novel here” is the researchers examined distressing dreams – not more physical sleep disturbances and disorders such as insomnia or apnea.

“However, nightmares can disturb sleep in the same way these disorders do by waking people up in the middle of the night,” said Dr. Carrillo, who was not involved with the study.

“Previous research has pointed to nightmares being indicative of potential changes in the brain that can precede other dementias like Parkinson’s disease. More research is needed to tease out what exactly is happening in the brain during nightmares that may be contributing to this increased risk,” she said.

Dr. Carrillo noted that “getting good sleep” is important for overall health, which includes brain health.

“The good news is there are treatments – both drug and nondrug – that can help address sleep disturbances,” she added.

This study received no external funding. Dr. Otaiku and Dr. Carrillo have reported no relevant financial relationships.

A look at the top cardiovascular disease (CVD) diagnoses in U.S. emergency departments (EDs) suggests that many heart-related emergencies are due to poorly controlled high blood pressure.

In a study of more than 20 million ED visits, about one-third of CVD-related ED visits in the United States were for hypertension-related conditions.

Overall, 13% of ED visits, representing more than 2.7 million individuals, were for essential hypertension.

Nationwide sample

The researchers studied more than 20.6 million ED encounters in adults with a primary CVD diagnosis using data from the Nationwide Emergency Department Sample between 2016 and 2018.

In the sample, 49% were women, and the median age was 67 years. Men had poorer overall baseline cardiometabolic profiles, but women had higher rates of obesity, hypertension, and cerebrovascular disease. The majority had Medicare or Medicaid insurance.

In women, essential hypertension was the most common reason for an ED visit (16%), followed by hypertensive heart or kidney disease (14%) and atrial fibrillation (AF)/flutter (10%).

In men, the top three reasons were hypertensive heart or kidney disease (15%), essential hypertension (11%), and acute myocardial infarction (AMI, 11%).

On presentation, women were significantly more likely to have essential hypertension, hypertensive crisis, AF/flutter, supraventricular tachycardia, pulmonary embolism, or ischemic stroke, while men were more likely to have AMI, or cardiac arrest.

“Previous studies have shown sex differences in patterns of CVD among hospitalized patients,” Dr. Mamas noted. “However, examining CVD encounters in the ED provides a more complete picture of the cardiovascular healthcare needs of men and women, as it captures encounters prior to hospitalization.”

He noted that previous studies of CVD emergency visits are limited to suspected MI visits. “Therefore, this analysis of 15 CVD conditions helps to better understand the full spectrum of acute CVD needs, including sex disparities in hospitalization and risk of death,” Dr. Mamas said.
 

Sex differences in outcomes

The study found that outcomes from the emergency CVD visits were slightly different for men and women.

Overall, women were less likely than were men to die (3.3% vs. 4.3%) or be hospitalized (49.1% vs. 52.3%) after an ED visit for CVD. The difference may be due to women’s generally lower-risk diagnoses, Dr. Mamas said, but there could be an underestimation of deaths in women.

In logistic regression models adjusted for baseline covariates, women with intracranial hemorrhage (ICH) had a higher risk of being admitted to hospital or dying compared with men with ICH.

Men were more likely to die if they presented with hypertensive heart or kidney disease, AF/flutter, AMI or cardiac arrest, the researchers found. 

“We did not track deaths outside of the hospital setting,” Dr. Mamas pointed out. Given past evidence that women are more likely to be inappropriately discharged from the ED, and strong evidence for the systemic undertreatment of women, further study is warranted to track outcomes beyond the ED visit,” he added.

The researchers called for further research into understanding the underlying factors driving the differences in CVD patterns and outcomes between men and women.

Reached for comment, Maryann McLaughlin, MD, a cardiologist at Mount Sinai Hospital, New York, said: “Hypertension is a silent killer” and this study “reiterates that people need to get their blood pressure checked more regularly.

“In the very least, if they do present to the hospital as not feeling well or whatever it is, and they are identified as having high blood pressure, that’s an important opportunity to really teach them about hypertension and have them follow-up with it,” Dr. McLaughlin told this news organization. 

The study was supported by Health Data Research UK. Dr. Keele and Dr. McLaughlin have reported no relevant financial relationships.

“We did not track deaths outside of the hospital setting,” Dr. Mamas pointed out. Given past evidence that women are more likely to be inappropriately discharged from the ED, and strong evidence for the systemic undertreatment of women, further study is warranted to track outcomes beyond the ED visit,” he added.

The researchers called for further research into understanding the underlying factors driving the differences in CVD patterns and outcomes between men and women.

Reached for comment, Maryann McLaughlin, MD, a cardiologist at Mount Sinai Hospital, New York, said: “Hypertension is a silent killer” and this study “reiterates that people need to get their blood pressure checked more regularly.

“In the very least, if they do present to the hospital as not feeling well or whatever it is, and they are identified as having high blood pressure, that’s an important opportunity to really teach them about hypertension and have them follow-up with it,” Dr. McLaughlin told this news organization. 

The study was supported by Health Data Research UK. Dr. Keele and Dr. McLaughlin have reported no relevant financial relationships.

Sport climbing can help improve posture in patients with Parkinson’s disease, including older patients, new research suggests.

In a randomized controlled study, those who participated in scaling a wall using ropes and fixed anchors were less stooped at 12 weeks than was a control group that participated in some form of unsupervised physical activity.

The results underscore that it is never too late to learn a new sport or type of movement – and that this type of intervention may have big health payoffs, said study investigator Heidemarie Zach, MD, associate professor of neurology, Medical University of Vienna, Austria.

“There’s no hurdle too high over which you can’t climb, or burden you can’t conquer,”  said Dr. Zach. “As long as you can walk independently and walk up a stair, you can go climbing.”

The findings were presented at the International Congress of Parkinson’s Disease and Movement Disorders.
 

Common feature of Parkinson’s disease

The analysis is part of a larger project that included a 2021 study showing a reduced Unified Parkinson’s Disease Rating Scale Part III (UPDRS-III) score by almost 13 points in patients who participated in sport climbing. The activity was also significantly associated with improved bradykinesia, rigidity, and tremor.

The current analysis focused on stooped posture, which in addition to motor symptoms is a common feature of Parkinson’s disease. This postural deformity can result in significant discomfort, pain, and decreased quality of life.

Pharmaceutical treatments are mostly ineffective for postural deformities, the researchers noted. Physical therapy may help improve symptoms, but only a few randomized studies have examined improved posture in patients with Parkinson’s disease using physiotherapy in general and alternative sports in particular.

Sport climbing is “really unique” in Parkinson’s disease, said Dr. Zach, who has yet to come across other research on this intervention. A climber herself, she recommended it to one of her patients: A 79-year old man with Parkinson’s disease who was a walker and hiker, and who ended up loving the sport. She called him her “pilot patient.”

The single-center study included 48 adult participants up to age 78 years (mean age, 65) with mild to moderate Parkinson’s disease. Most were at Hoehn & Yahr stage 2, with some at stage 3. All had no previous climbing experience. Exclusion criteria included having a condition other than Parkinson’s disease.

The researchers randomly assigned participants to a sport climbing course or to a control group.

The sport climbing group had a 90-minute climbing session each week for 12 weeks in an indoor gym. Under the supervision of an instructor, they were harnessed and connected to ropes with mats placed on the ground for safety.

The climbing wall was about 15 meters (50 feet) high. Participants typically started at 2 or 3 meters (6.5 to 9.5 feet) and worked their way up, Dr. Zach noted.

Those in the control group were asked to participate for 12 weeks in unsupervised physical activity, as recommended by the World Health Organization and the European Physiotherapy Guidelines for Parkinson’s Disease. This included at least 2.5 hours of moderate-intensity activity or 75 minutes of vigorous activity each week.
 

Whole-body workout

The primary outcome was improvement in posture, measured using a “simple” but highly reliable tool, said Dr. Zach. While the patients stood with their backs straight against a wall, researchers measured the distance in centimeters between the C7 sagittal vertical axis (C7SVA) and the wall.

The mean C7SVA at baseline did not significantly differ between the two groups, at 8.2 cm for the climbing group versus  7.7 cm for the control group. However, results showed only sport climbing was associated with significantly lessened forward flexion of the cervical spine.

The climbing group showed a decrease of the C7SVA by 1.7 cm (95% confidence interval [CI], 0.8-2.6 cm). “So climbers were more erect and less stooped after 12 weeks,” Dr. Zach said.

She noted that the mean difference in the control group was 0.5 cm (95% confidence interval [CI], –0.2 to 1.3 cm), which “is almost nothing.”

There did not seem to be any predictor, such as age, sex, or body mass index, for what patient subgroups benefit the most from the intervention, Dr. Zach noted.

In explaining why climbing helps posture, she said it is akin to “a whole-body workout.” The activity increases upper-body strength by using back and shoulder girdle muscles, as well as joint flexibility, Dr. Zach noted. Movements involved in climbing, such as repeated reaching for a distant hold, stretch the muscles of the hip flexors and hip.

As these movements reduce rigidity, the climbing action may also promote an upright posture. And as wall climbing involves planning and executing movements, it trains spatial body awareness, an important component of maintaining and correcting posture, she said.

Dr. Zach noted a motivational group dynamic likely also contributed to the success of the intervention. “They were cheering each other at the bottom” of the climbing wall, she said.

The results show that posture can be added to the improvements in Parkinson’s disease already documented from climbing, including improved motor symptoms, rigidity, and tremor, she said. The next step on the research agenda is to show whether the intervention has a positive impact on gait, Dr. Zach added.
 

‘Quite adventurous’

Commenting on the research, Rebecca Gilbert, MD, PhD, chief scientific officer at the American Parkinson Disease Association, said she welcomes “any new idea” to help patients with Parkinson’s disease – and that sport climbing sounds “quite adventurous.”

“The general concept that you’re asking the body to move in a novel way is a good thing for everyone and especially for people with Parkinson’s disease,” said Dr. Gilbert, who was not involved with the research.

She noted that in Parkinson’s disease, an ideal exercise intervention includes a combination of four modalities: stretching, balance, aerobics, and strengthening. Rope climbing involves many of these, in addition to a cognitive element, Dr. Gilbert said. It’s also important that patients with Parkinson’s disease participate in an activity they enjoy, she added.

However, she stressed that safety has to be “weighed,” especially for patients with stage 3 Parkinson’s disease, who often have balance problems. “It may be difficult to climb a rope if you have balance problems,” Dr. Gilbert said. “The intervention needs to be tailored to the existing disability, and perhaps this activity is more a reasonable thing for patients at milder stages.”

Dr. Zach and Dr. Gilbert have reported no relevant financial relationships.

A high baseline intake of vitamin B₁₂ is linked to lower risk of developing Parkinson’s disease, new research suggests. “The results leave the door open for the possibility that vitamin B₁₂ may have a beneficial effect in protecting against Parkinson’s disease,” said lead author Mario H. Flores, PhD, a research fellow at Harvard T.H. Chan School of Public Health, Boston.

The findings were presented at the International Congress of Parkinson’s Disease and Movement Disorders.
 

B vitamins and Parkinson’s disease

Previous preclinical studies have suggested that B vitamins protect against Parkinson’s disease by decreasing plasma homocysteine levels and through other neuroprotective effects. However, there have been only two epidemiologic studies of B vitamins in Parkinson’s disease – and their results were inconsistent, Dr. Flores noted.

The new study included 80,965 women from the Nurses’ Health Study and 48,837 men from the Health Professionals Follow-up Study. All completed a food frequency questionnaire at baseline and every 4 years.

Researchers collected information on dietary, supplemental, and total intake of folate, vitamin B₆, and vitamin B₁₂ over the course of about 30 years up to 2012. They estimated hazard ratios and 95% confidence intervals for Parkinson’s disease according to quintiles of cumulative average intake.

During follow-up, 495 women and 621 men were diagnosed with Parkinson’s disease.

The investigators adjusted for potential confounders, including age, year, smoking status, physical activity, intake of alcohol or caffeine, hormone use (in women), intake of dairy and flavonoids, and Mediterranean diet score.

Analyses of cumulative average total folate, B₆, and B₁₂ intake were not associated with Parkinson’s disease risk. “The results of the primary analysis of cumulative intake were not significant for any of the vitamins we looked at,” said Dr. Flores.

Researchers also conducted secondary analyses, including assessment of how the most recent intake of B vitamins related to Parkinson’s disease risk. This analysis also did not find a significant association.

However, when examining baseline intake of vitamin B₁₂, “we saw some suggestion for a potential inverse association with Parkinson’s disease,” Dr. Flores said.

Among individuals with higher total intake of vitamin B₁₂, there was a lower risk for Parkinson’s disease (pooled hazard ratio for top vs. bottom quintile, 0.74; 95% confidence interval [CI], 0.60-0.89; P for trend, .001). Intake from both diet and supplements contributed to this inverse association, the investigators noted.

Dietary sources of vitamin B₁₂ include poultry, meat, fish, and dairy products; however, the main sources in this study were multivitamins/supplements and enriched foods such as cereals, said Dr. Flores.
 

Several limitations

In an attempt to overcome risk for reverse causality, the researchers examined B₁₂ intake during four lagged exposure periods: 8-, 12-, 16- and 20-year lags. They found a significant relationship between intake for the 20-year lag time and development of Parkinson’s disease.

Overall, the study results provide support for a possible protective effect of early intake of vitamin B₁₂ on the development of Parkinson’s disease, Dr. Flores noted.

In addition to being involved in the regulation of homocysteine levels, vitamin B₁₂ may help regulate leucine-rich repeat kinase 2 (LRRK2), an enzyme implicated in the pathogenesis of Parkinson’s disease, he said.

However, the study did not examine how B₁₂ deficiency might relate to risk for Parkinson’s disease, which “is something worth looking at in future studies,” said Dr. Flores.

He added that although findings from a single study cannot translate into recommendations on ideal vitamin B₁₂ intake to prevent or delay Parkinson’s disease onset, the median intake in the highest quintile that the study linked to less Parkinson’s disease risk was 18 mcg/d at baseline. The amount in multivitamins can vary from 5 to 25 mcg.

Dr. Flores said a limitation of the study was that it included U.S. health care professionals, “most of whom arguably have very good nutritional status.”

As well, assessment of vitamin B intake was self-reported, so there might have been measurement error – and there may have been an unmeasured confounding factor that could explain the associations.

Dr. Flores also stressed that the effect of B₁₂ on Parkinson’s disease risk “was very modest,” and the results need to be confirmed in other studies “ideally looking at circulating levels of vitamin B₁₂.”
 

Not ready to recommend

Commenting on the research, Michael S. Okun, MD, medical adviser at the Parkinson’s Foundation and professor and director of the Norman Fixel Institute for Neurological Diseases at the University of Florida, Gainesville, noted that other recent studies have suggested high-dose B₁₂ may be preventive and a possible treatment in Parkinson’s disease.

“Although only a secondary aim of the current study, there was a reported potential benefit” in this new study, too, said Dr. Okun, who was not involved with the research.

However, the evidence is still not strong enough to change prescribing habits, he noted. “We do not recommend high-dose B₁₂ either for those at genetic risk of Parkinson’s or those already with the disease,” Dr. Okun said.

He added that because multiple recent studies have questioned the beneficial effects for multivitamin combinations used to prevent neurologic diseases, “it wasn’t surprising to see results showing a lack of protection against later-onset Parkinson’s disease with [cumulative] folate, B₆, and B₁₂ intake” in the current study.

The study was supported by the NIH. Dr. Flores and Dr. Okun have reported no relevant financial relationships.

Overall, the study results provide support for a possible protective effect of early intake of vitamin B₁₂ on the development of Parkinson’s disease, Dr. Flores noted.

In addition to being involved in the regulation of homocysteine levels, vitamin B₁₂ may help regulate leucine-rich repeat kinase 2 (LRRK2), an enzyme implicated in the pathogenesis of Parkinson’s disease, he said.

However, the study did not examine how B₁₂ deficiency might relate to risk for Parkinson’s disease, which “is something worth looking at in future studies,” said Dr. Flores.

He added that although findings from a single study cannot translate into recommendations on ideal vitamin B₁₂ intake to prevent or delay Parkinson’s disease onset, the median intake in the highest quintile that the study linked to less Parkinson’s disease risk was 18 mcg/d at baseline. The amount in multivitamins can vary from 5 to 25 mcg.

Dr. Flores said a limitation of the study was that it included U.S. health care professionals, “most of whom arguably have very good nutritional status.”

As well, assessment of vitamin B intake was self-reported, so there might have been measurement error – and there may have been an unmeasured confounding factor that could explain the associations.

Dr. Flores also stressed that the effect of B₁₂ on Parkinson’s disease risk “was very modest,” and the results need to be confirmed in other studies “ideally looking at circulating levels of vitamin B₁₂.”
 

Not ready to recommend

Commenting on the research, Michael S. Okun, MD, medical adviser at the Parkinson’s Foundation and professor and director of the Norman Fixel Institute for Neurological Diseases at the University of Florida, Gainesville, noted that other recent studies have suggested high-dose B₁₂ may be preventive and a possible treatment in Parkinson’s disease.

“Although only a secondary aim of the current study, there was a reported potential benefit” in this new study, too, said Dr. Okun, who was not involved with the research.

However, the evidence is still not strong enough to change prescribing habits, he noted. “We do not recommend high-dose B₁₂ either for those at genetic risk of Parkinson’s or those already with the disease,” Dr. Okun said.

He added that because multiple recent studies have questioned the beneficial effects for multivitamin combinations used to prevent neurologic diseases, “it wasn’t surprising to see results showing a lack of protection against later-onset Parkinson’s disease with [cumulative] folate, B₆, and B₁₂ intake” in the current study.

The study was supported by the NIH. Dr. Flores and Dr. Okun have reported no relevant financial relationships.
