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.

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.

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.

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.

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.

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.

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.

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.

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.

Recently an article crossed my screen that drinking 4 cups of tea per day lowered the risk of type 2 diabetes by 17%. As these thing always seem to, it ended with a variant of “further research is needed.”

Encouraging? Sure. Definite? Nope.

That’s the trouble with a lot of research papers. They have some promise, but really nothing definite. I’ve seen plenty of articles suggesting coffee and/or tea have health benefits, though specifically on what varies, from lifespan to lowering the risk of a chronic medical condition (in this case, type 2 diabetes).

There are always numerous variables that aren’t clear. What kind of tea? Decaf or regular? Hot or iced? When you say cup, what do you mean? A lot of people, including me, probably consider anything smaller that a Starbucks grande to be for wimps.

While I can’t think of any off the top of my head, there’s probably a reasonable chance that, if I looked, I could find something that says coffee or tea are bad for you in some way, too.

Not that I’m planning on changing my already caffeinated drinking habits, which is probably the crux of these things for most of us. In a given day I have 1-2 cups of coffee and 3-4 bottles of diet green tea. Maybe 1-2 Diet Cokes in there some days. In winter more hot black tea. I’m probably a poster child for methylyxanthine toxicity.

I have no idea if all that coffee and tea are doing anything besides keeping me awake and alert for my patients. If they are, I certainly hope they’re lowering my risk of something bad.

Articles like this always get attention, and are often picked up by the general media. People love to think something so simple as drinking more tea or coffee would make a big difference in their lives. So it gets forwarded, people never read past the first paragraph or two, and don’t make it to the “further research is needed” line.

If an article ever came out refuting it, it probably wouldn’t get nearly as much press (who wants to read bad news?) and would be quickly forgotten outside of medical circles.

But the reality is that people are really looking for shortcuts. Unless you live under a rock, it’s pretty clear to both medical and lay people that such things as exercise and a healthy diet can help avoid multiple chronic health conditions. This doesn’t mean most of us, myself included, will do such faithfully. It just takes less time and effort to drink more tea than it does to go to the gym, so we want to believe.

That’s just human nature.

Entrepreneur Maya McNulty, 49, was one of the first victims of the COVID-19 pandemic. The Schenectady, N.Y., businesswoman spent 2 months in the hospital after catching the disease in March 2020. That September, she was diagnosed with long COVID.

“Even a simple task such as unloading the dishwasher became a major challenge,” she says.

Over the next several months, Ms. McNulty saw a range of specialists, including neurologists, pulmonologists, and cardiologists. She had months of physical therapy and respiratory therapy to help regain strength and lung function. While many of the doctors she saw were sympathetic to what she was going through, not all were.

“I saw one neurologist who told me to my face that she didn’t believe in long COVID,” she recalls. “It was particularly astonishing since the hospital they were affiliated with had a long COVID clinic.”

Ms. McNulty began to connect with other patients with long COVID through a support group she created at the end of 2020 on the social media app Clubhouse. They exchanged ideas and stories about what had helped one another, which led her to try, over the next year, a plant-based diet, Chinese medicine, and vitamin C supplements, among other treatments.

She also acted on unscientific reports she found online and did her own research, which led her to discover claims that some asthma patients with chronic coughing responded well to halotherapy, or dry salt therapy, during which patients inhale micro-particles of salt into their lungs to reduce inflammation, widen airways, and thin mucus. She’s been doing this procedure at a clinic near her home for over a year and credits it with helping with her chronic cough, especially as she recovers from her second bout of COVID-19.

It’s not cheap – a single half-hour session can cost up to $50 and isn’t covered by insurance. There’s also no good research to suggest that it can help with long COVID, according to the Cleveland Clinic.

Ms. McNulty understands that but says many people who live with long COVID turn to these treatments out of a sense of desperation.

“When it comes to this condition, we kind of have to be our own advocates. People are so desperate and feel so gaslit by doctors who don’t believe in their symptoms that they play Russian roulette with their body,” she says. “Most just want some hope and a way to relieve pain.”

Across the country, 16 million Americans have long COVID, according to the Brookings Institution’s analysis of a 2022 Census Bureau report. The report also estimated that up to a quarter of them have such debilitating symptoms that they are no longer able to work. While long COVID centers may offer therapies to help relieve symptoms, “there are no evidence-based established treatments for long COVID at this point,” says Andrew Schamess, MD, a professor of internal medicine at Ohio State Wexner Medical Center, who runs its Post-COVID Recovery Program. “You can’t blame patients for looking for alternative remedies to help them. Unfortunately, there are also a lot of people out to make a buck who are selling unproven and disproven therapies.”
 

Sniffing out the snake oil

With few evidence-based treatments for long COVID, patients with debilitating symptoms can be tempted by unproven options. One that has gotten a lot of attention is hyperbaric oxygen. This therapy has traditionally been used to treat divers who have decompression sickness, or “the bends.” It’s also being touted by some clinics as an effective treatment for long COVID.

A very small trial of 73 patients with long COVID, published in the journal Scientific Reports, found that those treated in a high-pressure oxygen system 5 days a week for 2 months showed improvements in brain fog, pain, energy, sleep, anxiety, and depression, compared with similar patients who got sham treatments. But larger studies are needed to show how well it works, notes Dr. Schamess.

“It’s very expensive – roughly $120 per session – and there just isn’t the evidence there to support its use,” he says.

In addition, the therapy itself carries risks, such as ear and sinus pain, middle ear injury, temporary vision changes, and, very rarely, lung collapse, according to the U.S. Food and Drug Administration.

One “particularly troubling” treatment being offered, says Kathleen Bell, MD, chair of the department of physical medicine and rehabilitation at the University of Texas Southwestern Medical Center, is stem cell therapy. This therapy is still in its infancy, but it’s being marketed by some clinics as a way to prevent COVID-19 and also treat long-haul symptoms.

The FDA has issued advisories that there are no products approved to treat long COVID and recommends against their use, except in a clinical trial.

“There’s absolutely no regulation – you don’t know what you’re getting, and there’s no research to suggest this therapy even works,” says Dr. Bell. It’s also prohibitively expensive – one Cayman Islands–based company advertises its treatment for as much as $25,000.

Patients with long COVID are even traveling as far as Cyprus, Germany, and Switzerland for a procedure known as blood washing, in which large needles are inserted into veins to filter blood and remove lipids and inflammatory proteins, the British Medical Journal reported in July. Some patients are also prescribed blood thinners to remove microscopic blood clots that may contribute to long COVID. But this treatment is also expensive, with many people paying $10,000-$15,000 out of pocket, and there’s no published evidence to suggest it works, according to the BMJ.

It can be particularly hard to discern what may work and what’s unproven, since many primary care providers are themselves unfamiliar with even traditional long COVID treatments, Dr. Bell says.
 

Sorting through supplements

Yufang Lin, MD, an integrative specialist at the Cleveland Clinic, says many patients with long COVID enter her office with bags of supplements.

“There’s no data on them, and in large quantities, they may even be harmful,” she says.

Instead, she works closely with the Cleveland Clinic’s long COVID center to do a thorough workup of each patient, which often includes screening for certain nutritional deficiencies.

“Anecdotally, we do see many patients with long COVID who are deficient in these vitamins and minerals,” says Dr. Lin. “If someone is low, we will suggest the appropriate supplement. Otherwise, we work with them to institute some dietary changes.”

This usually involves a plant-based, anti-inflammatory eating pattern such as the Mediterranean diet, which is rich in fruits, vegetables, whole grains, nuts, fatty fish, and healthy fats such as olive oil and avocados.

Other supplements some doctors recommend for patients with long COVID are meant to treat inflammation, Dr. Bell says, although there’s not good evidence they work. One is the antioxidant coenzyme Q10.

But a small preprint study published in The Lancet, of 121 patients with long COVID who took 500 milligrams a day of coenzyme Q10 for 6 weeks saw no differences in recovery, compared with those who took a placebo. Because the study is still a preprint, it has not been peer-reviewed.

Another is probiotics. A small study, published in the journal Infectious Diseases Diagnosis & Treatment, found that a blend of five lactobacillus probiotics, along with a prebiotic called inulin, taken for 30 days, helped with long-term COVID symptoms such as coughing and fatigue. But larger studies need to be done to support their use.

One that may have more promise is omega-3 fatty acids. Like many other supplements, these may help with long COVID by easing inflammation, says Steven Flanagan, MD, a rehabilitation medicine specialist at NYU Langone who works with long COVID patients. Researchers at the Mount Sinai School of Medicine, New York, are studying whether a supplement can help patients who have lost their sense of taste or smell after an infection, but results aren’t yet available.

Among the few alternatives that have been shown to help patients are mindfulness-based therapies – in particular, mindfulness-based forms of exercise such as tai chi and qi gong may be helpful, as they combine a gentle workout with stress reduction.

“Both incorporate meditation, which helps not only to relieve some of the anxiety associated with long COVID but allows patients to redirect their thought process so that they can cope with symptoms better,” says Dr. Flanagan.

A 2022 study, published in BMJ Open, found that these two activities reduced inflammatory markers and improved respiratory muscle strength and function in patients recovering from COVID-19.

“I recommend these activities to all my long COVID patients, as it’s inexpensive and easy to find classes to do either at home or in their community,” he says. “Even if it doesn’t improve their long COVID symptoms, it has other benefits such as increased strength and flexibility that can boost their overall health.”

Ms. McNulty began to connect with other patients with long COVID through a support group she created at the end of 2020 on the social media app Clubhouse. They exchanged ideas and stories about what had helped one another, which led her to try, over the next year, a plant-based diet, Chinese medicine, and vitamin C supplements, among other treatments.

She also acted on unscientific reports she found online and did her own research, which led her to discover claims that some asthma patients with chronic coughing responded well to halotherapy, or dry salt therapy, during which patients inhale micro-particles of salt into their lungs to reduce inflammation, widen airways, and thin mucus. She’s been doing this procedure at a clinic near her home for over a year and credits it with helping with her chronic cough, especially as she recovers from her second bout of COVID-19.

It’s not cheap – a single half-hour session can cost up to $50 and isn’t covered by insurance. There’s also no good research to suggest that it can help with long COVID, according to the Cleveland Clinic.

Ms. McNulty understands that but says many people who live with long COVID turn to these treatments out of a sense of desperation.

“When it comes to this condition, we kind of have to be our own advocates. People are so desperate and feel so gaslit by doctors who don’t believe in their symptoms that they play Russian roulette with their body,” she says. “Most just want some hope and a way to relieve pain.”

Across the country, 16 million Americans have long COVID, according to the Brookings Institution’s analysis of a 2022 Census Bureau report. The report also estimated that up to a quarter of them have such debilitating symptoms that they are no longer able to work. While long COVID centers may offer therapies to help relieve symptoms, “there are no evidence-based established treatments for long COVID at this point,” says Andrew Schamess, MD, a professor of internal medicine at Ohio State Wexner Medical Center, who runs its Post-COVID Recovery Program. “You can’t blame patients for looking for alternative remedies to help them. Unfortunately, there are also a lot of people out to make a buck who are selling unproven and disproven therapies.”
 

Sniffing out the snake oil

With few evidence-based treatments for long COVID, patients with debilitating symptoms can be tempted by unproven options. One that has gotten a lot of attention is hyperbaric oxygen. This therapy has traditionally been used to treat divers who have decompression sickness, or “the bends.” It’s also being touted by some clinics as an effective treatment for long COVID.

A very small trial of 73 patients with long COVID, published in the journal Scientific Reports, found that those treated in a high-pressure oxygen system 5 days a week for 2 months showed improvements in brain fog, pain, energy, sleep, anxiety, and depression, compared with similar patients who got sham treatments. But larger studies are needed to show how well it works, notes Dr. Schamess.

“It’s very expensive – roughly $120 per session – and there just isn’t the evidence there to support its use,” he says.

In addition, the therapy itself carries risks, such as ear and sinus pain, middle ear injury, temporary vision changes, and, very rarely, lung collapse, according to the U.S. Food and Drug Administration.

One “particularly troubling” treatment being offered, says Kathleen Bell, MD, chair of the department of physical medicine and rehabilitation at the University of Texas Southwestern Medical Center, is stem cell therapy. This therapy is still in its infancy, but it’s being marketed by some clinics as a way to prevent COVID-19 and also treat long-haul symptoms.

The FDA has issued advisories that there are no products approved to treat long COVID and recommends against their use, except in a clinical trial.

“There’s absolutely no regulation – you don’t know what you’re getting, and there’s no research to suggest this therapy even works,” says Dr. Bell. It’s also prohibitively expensive – one Cayman Islands–based company advertises its treatment for as much as $25,000.

Patients with long COVID are even traveling as far as Cyprus, Germany, and Switzerland for a procedure known as blood washing, in which large needles are inserted into veins to filter blood and remove lipids and inflammatory proteins, the British Medical Journal reported in July. Some patients are also prescribed blood thinners to remove microscopic blood clots that may contribute to long COVID. But this treatment is also expensive, with many people paying $10,000-$15,000 out of pocket, and there’s no published evidence to suggest it works, according to the BMJ.

It can be particularly hard to discern what may work and what’s unproven, since many primary care providers are themselves unfamiliar with even traditional long COVID treatments, Dr. Bell says.
 

Sorting through supplements

Yufang Lin, MD, an integrative specialist at the Cleveland Clinic, says many patients with long COVID enter her office with bags of supplements.

“There’s no data on them, and in large quantities, they may even be harmful,” she says.

Instead, she works closely with the Cleveland Clinic’s long COVID center to do a thorough workup of each patient, which often includes screening for certain nutritional deficiencies.

“Anecdotally, we do see many patients with long COVID who are deficient in these vitamins and minerals,” says Dr. Lin. “If someone is low, we will suggest the appropriate supplement. Otherwise, we work with them to institute some dietary changes.”

This usually involves a plant-based, anti-inflammatory eating pattern such as the Mediterranean diet, which is rich in fruits, vegetables, whole grains, nuts, fatty fish, and healthy fats such as olive oil and avocados.

Other supplements some doctors recommend for patients with long COVID are meant to treat inflammation, Dr. Bell says, although there’s not good evidence they work. One is the antioxidant coenzyme Q10.

But a small preprint study published in The Lancet, of 121 patients with long COVID who took 500 milligrams a day of coenzyme Q10 for 6 weeks saw no differences in recovery, compared with those who took a placebo. Because the study is still a preprint, it has not been peer-reviewed.

Another is probiotics. A small study, published in the journal Infectious Diseases Diagnosis & Treatment, found that a blend of five lactobacillus probiotics, along with a prebiotic called inulin, taken for 30 days, helped with long-term COVID symptoms such as coughing and fatigue. But larger studies need to be done to support their use.

One that may have more promise is omega-3 fatty acids. Like many other supplements, these may help with long COVID by easing inflammation, says Steven Flanagan, MD, a rehabilitation medicine specialist at NYU Langone who works with long COVID patients. Researchers at the Mount Sinai School of Medicine, New York, are studying whether a supplement can help patients who have lost their sense of taste or smell after an infection, but results aren’t yet available.

Among the few alternatives that have been shown to help patients are mindfulness-based therapies – in particular, mindfulness-based forms of exercise such as tai chi and qi gong may be helpful, as they combine a gentle workout with stress reduction.

“Both incorporate meditation, which helps not only to relieve some of the anxiety associated with long COVID but allows patients to redirect their thought process so that they can cope with symptoms better,” says Dr. Flanagan.

A 2022 study, published in BMJ Open, found that these two activities reduced inflammatory markers and improved respiratory muscle strength and function in patients recovering from COVID-19.

“I recommend these activities to all my long COVID patients, as it’s inexpensive and easy to find classes to do either at home or in their community,” he says. “Even if it doesn’t improve their long COVID symptoms, it has other benefits such as increased strength and flexibility that can boost their overall health.”

Entrepreneur Maya McNulty, 49, was one of the first victims of the COVID-19 pandemic. The Schenectady, N.Y., businesswoman spent 2 months in the hospital after catching the disease in March 2020. That September, she was diagnosed with long COVID.

“Even a simple task such as unloading the dishwasher became a major challenge,” she says.

Over the next several months, Ms. McNulty saw a range of specialists, including neurologists, pulmonologists, and cardiologists. She had months of physical therapy and respiratory therapy to help regain strength and lung function. While many of the doctors she saw were sympathetic to what she was going through, not all were.

Mexican researchers found no direct association between SARS-CoV-2 vaccination and worsening symptoms among 60 patients with Parkinson’s disease. Nonmotor symptoms seemed to improve after SARS-CoV-2 vaccination, although the investigators could not verify a causal relationship.

Vaccination programs should continue for patients with Parkinson’s disease, they said, reporting their clinical results at the International Congress of Parkinson’s Disease and Movement Disorders.

The International Parkinson and Movement Disorder Society has recommended vaccining patients with Parkinson’s disease. “All approved mRNA-based and viral vector vaccines are not expected to interact with Parkinson’s disease, but patients [still] report concern with regard to the benefits, risks, and safeness in Parkinson’s disease,” Mayela Rodríguez-Violante, MD, MSc, and colleagues wrote in an abstract of their findings.

Social isolation may be contributing to these beliefs and concerns, though this is inconclusive.

Investigators from Mexico City conducted a retrospective study of patients with Parkinson’s disease to see how COVID-19 vaccination affected motor and nonmotor symptoms. They enlisted 60 patients (66.7% were male; aged 65.7 ± 11.35 years) who received either a vector-viral vaccine (Vaxzevria Coronavirus) or an mRNA vaccine (BNT162b2).

A Wilcoxon signed-rank test assessed scale differences before and after vaccination, measuring motor involvement (Unified Parkinson’s Disease Rating Scale), nonmotor involvement (Non-Motor Rating Scale [NMSS]), cognitive impairment (Montreal Cognitive Assessment), and quality of life (8-item Parkinson’s Disease Questionnaire index).

Investigators found no significant difference between scales, although they did notice a marked improvement in non-motor symptoms.

“The main takeaway is that vaccination against COVID-19 does not appear to worsen motor or nonmotor symptoms in persons with Parkinson’s disease. The benefits outweigh the risks,” said Dr. Rodríguez-Violante, the study’s lead author and a movement disorder specialist at the National Institute of Neurology and Neurosurgery, Mexico City.

Next steps are to increase the sample size to see if it’s possible to have a similar number in terms of type of vaccine, said Dr. Rodríguez-Violante. “Also, the data presented refers to primary series doses so booster effects will also be studied.”

Few studies have looked at vaccines and their possible effects on this patient population. However, a 2021 study of 181 patients with Parkinson’s disease reported that 2 (1.1%) had adverse effects after receiving the BNT162b2 mRNA vaccine. One of the patients, a 61-year-old woman with a decade-long history of Parkinson’s disease, developed severe, continuous, generalized dyskinesia 6 hours after a first dose of vaccine. The second patient was 79 years old and had Parkinson’s disease for 5 years. She developed fever, confusion, delusions, and continuous severe dyskinesia for 3 days following her vaccination.

“This highlights that there is a variability in the response triggered by the vaccine that might likely depend on individual immunological profiles … clinicians should be aware of this possibility and monitor their patients after they receive their vaccination,” Roberto Erro, MD, PhD and colleagues wrote in the Movement Disorders journal.
