When the Delta variant of the coronavirus was first identified in India in December 2020, the threat may have seemed too remote to trigger worry in the United States, although the horror of it ripping through the country was soon hard to ignore.

Within months, the Delta variant had spread to more than 98 countries, including Scotland, the United Kingdom, Israel, and now, of course, the United States. The CDC said this week the Delta variant now accounts for 93% of all COVID cases.

Fueled by Delta, COVID-19 cases, hospitalizations, and deaths are increasing in nearly all states, according to the latest CDC data. After the 7-day average number of cases dipped by June 22 to about 11,000, it rose by Aug. 3 to more than 85,000.

Some experts are heartened by the recent decrease in COVID-19 cases in the United Kingdom and India, both hard-hit with the Delta variant. COVID-19 cases in India peaked at more than 400,000 a day in May; by Aug. 2, that had dropped to about 30,500 daily.

Andy Slavitt, former Biden White House senior adviser for COVID-19 response, tweeted July 26 that, if the Delta variant acted the same in the United Kingdom as in India, it would have a quick rise and a quick drop.

The prediction seems to have come true. As of Aug. 3, U.K. cases have dropped to 7,467, compared with more than 46,800 July 19.

So the question of the summer has become: “When will Delta burn out here?”

Like other pandemic predictions, these are all over the board. Here are five predictions about when COVID cases will peak, then fall. They range from less than 2 weeks to more than 2 months:

• Mid-August: Among the most optimistic predictions of when the Delta-driven COVID-19 cases will decline is from Scott Gottlieb, MD, former FDA director. He told CNBC on July 28 that he would expect cases to decline in 2-3 weeks – so by August 11.
• Mid-August to mid-September: Ali Mokdad, PhD, chief strategy officer for population health at the University of Washington, Seattle, said that, “right now for the U.S. as a country, cases will peak mid-August” and then decline. He is citing projections by the university’s Institute for Health Metrics and Evaluation. In its “most likely” scenario, it predicts COVID deaths will peak at about 1,000 daily by mid-September, then decline. (As of Aug. 3, daily deaths averaged 371.)
• September: “I am hoping we get over this Delta hump [by then],” says Eric Topol, MD, founder and director of the Scripps Research Translational Institute in La Jolla, Calif., and editor-in-chief of Medscape. “But sometimes, I am too much of an optimist.”
• Mid-October: Experts at the COVID-19 Scenario Modeling Hub, a consortium of researchers from leading institutions who consult with the CDC, said the Delta-fueled pandemic will steadily increase through summer and fall, with a mid-October peak.
• Unclear: Because cases are underestimated, “I think it is unclear when we will see a peak of Delta,” says Amesh Adalja, MD, a senior scholar at the Johns Hopkins Center for Health Security, Baltimore. He predicts a decline in cases as “more people get infected and develop natural immunity.”

The predictions are based on different scenarios, such as most likely or worst case. Factors such as personal behaviors, public mandates, and vaccination rates could all alter the projections.
 

What a difference vaccination may make

An uptick in vaccinations could change all the models and predictions, experts agree. As of Aug. 3, almost half (49.7%) of the total U.S. population was fully vaccinated, the CDC said. (And 80.1% of those 65 and over were.)

But that’s a long way from the 70% or 80% figure often cited to reach herd immunity. Recently, Ricardo Franco, MD, of the University of Alabama at Birmingham, said at a briefing by the Infectious Diseases Society of America that the infectiousness of the Delta variant may mean the herd immunity threshold is actually closer to 90%.

Dr. Mokdad estimates that by Nov. 1, based on the current rate of infections, 64% of people in the United States will be immune to a variant like Delta, taking into account those already infected and those vaccinated against COVID-19.

Justin Lessler, PhD, a University of North Carolina at Chapel Hill epidemiologist involved in the modeling hub, says if enough people get vaccinated, it could stop the Delta variant in its tracks. But that percentage is high.

“I am relatively confident that if we could get 90% or more of the eligible population vaccinated that we would see the epidemic begin to recede,” he says.

It’s a huge leap from 50%, or even 64%, to 90%. Could the Delta surge really motivate that many people to head to a vaccination site?

That’s hard to predict, Dr. Topol said. Some unvaccinated people may feel like soldiers in a foxhole, especially if they are in hard-hit states like Louisiana, and rush to get the vaccine as soon as possible. Others, hearing about the “breakthrough” cases in the vaccinated, may dig in their heels and ask: “Why bother?” as they mistakenly conclude that the vaccine has not done its job.
 

Roles of public policy, individual behavior

Besides an increase in vaccinations, individual behaviors and mandates can change the scenario. Doctors can remind even vaccinated patients that behaviors such as social distancing and masks still matter, experts said.

“Don’t ‘stress test’ your vaccine, “ Dr. Topol said.

The vaccines against COVID are good but not perfect and, he notes, they offer less protection if many months have passed since the vaccines were given.

The best advice now, Dr. Topol said, is: “Don’t be inside without a mask.”

Even if outdoors, depending on how close others are and the level of the conversation, a mask might be wise, he says.

Dr. Mokdad finds that “when cases go up, people put on their best behavior,” such as going back to masks and social distancing.

“Unfortunately, we have two countries,” he said, referring to the way public health measures and mandates vary from state to state.
 

Once the Delta variant subsides, what’s next?

It’s not a matter of if there is another variant on the heels of Delta, but when, Dr. Topol and other experts said. A new variant, Lambda, was first identified in Peru in August 2020 but now makes up about 90% of the country’s infections.

There’s also Delta-plus, just found in two people in South Korea.

Future variants could be even more transmissible than Delta, “which would be a horror show,” Dr. Topol said. “This [Delta] is by far the worst version. The virus is going to keep evolving. It is not done with us.”
 

On the horizon: Variant-proof vaccines

What’s needed to tackle the next variant is another approach to vaccine development, according to Dr. Topol and his colleague, Dennis R. Burton, a professor of immunology and microbiology at Scripps Research Institute.

Writing a commentary in Nature published in 2021, the two propose using a special class of protective antibodies, known as broadly neutralizing antibodies, to develop these vaccines. The success of the current COVID-19 vaccines is likely because of the vaccine’s ability to prompt the body to make protective neutralizing antibodies. These proteins bind to the viruses and prevent them from infecting the body’s cells.

The broadly neutralizing antibodies, however, can act against many different strains of related viruses, Dr. Topol and Mr. Burton wrote. Using this approach, which is already under study, scientists could make vaccines that would be effective against a family of viruses. The goal: to stop future outbreaks from becoming epidemics and then pandemics.

Bother me, I’m working 

Although some of us have been comfortably functioning in a virtual work environment, others are now trickling back into the office. And you know what that means? People come to your desk to show you pictures of their cat or tell you about their kid’s birthday party. You may sneer at the interruption, but a study shows you actually like it.

Rawpixel/Thinkstock

A team of researchers at the University of Cincinnati surveyed 111 full-time employees twice a day for 3 weeks about their work experience. They asked about mental exhaustion, workplace interruptions, sense of belonging, and overall job satisfaction. They found that employees had a higher sense of belonging and job satisfaction when interrupted with a social versus work interruption.

“Interruptions can actually benefit individuals from an interpersonal perspective – people feel like they belong when others come and talk to them or ask them questions, even while being distracted from their tasks,” said Heather C. Vough, senior investigator and a former university faculty member.

Chitchatting at work is often seen as a distraction, but this study suggests that it’s not like heating up fish in the breakroom microwave.

So the next time someone hits you with the “Hey, do you have a sec?,” do yourself a favor and enjoy the interruption.
 

A smorgasbord of science

It’s probably difficult to recruit patients for some medical trials. Try this new drug and potentially get all sorts of interesting and unpleasant side effects. Pass. We suggest the approach a group of researchers from the University of Kansas took for a recent study into weight gain: Invite a bunch of 20-something adults to an all-you-can-eat buffet. They’ll be beating down your door in no time.

pxfuel

Their study, published in Appetite, focused on hyperpalatable food – the sort of food you can keep eating – and compared it with high-energy-dense food and ultra processed food. The test patients had their body composition measured, were let loose on the buffet, and were measured again a year later.

The patients who favored salty/carbohydrate-filled hyperpalatable food (such as pretzels or popcorn) were much more likely to gain weight, compared with those who focused on salty/fat-filled food of any variety. As a matter of fact, those who stuck to fatty food during the buffet had no change in weight over the 1-year study period. The researchers noted that those who ate the carb-filled food tended more toward hedonic eating, or the act of eating simply for pleasure.

The study is no doubt helpful in the long battle against obesity and overeating, but it’s also a very helpful guide to getting the most bang for your buck at the buffet. Stay away from the cheap salty snack food. Go for the steak and seafood. Get your money’s worth. In the long run you won’t even gain any weight. No promises about tomorrow though.
 

There’s a cheat code for that

For a large percentage of kids and young adults, and maybe even older adults (we don’t judge), a storm warning means a cozy night in playing video games. Staying inside is probably the safest bet when there’s a storm, and the weatherman never says to avoid playing video games when there’s lightning.

xresch/Pixabay

Maybe he should, though, since a man from Tennessee reportedly got struck by lightning through his game controller. Emergency crews determined that lightning either hit the man’s house or struck near it and went through the controller. The type of console was not revealed, even though some people may want to know the specifics before playing during the next storm.

Luckily, the man was not seriously hurt and did not need to go to the hospital. This is apparently not unheard of, as a professional gamer was shocked through a wired controller last year, causing burns on her hands and a broken controller.

This might be our cue to do less electrical types of activities during thunderstorms, like knitting or reading by candlelight.
 

Freeze, squeeze, and enjoy … cramping

As you were ingesting last week’s installment of the never-ending buffet that is LOTME, you probably wondered: What’s going on? Where’s the latest bodily insult being perpetuated by the gang over at TikTok?

Daria-Yakovleva/Pixabay

Have no fear, good readers. We would never make you go 2 straight weeks without serving up some hyperpalatable TikTok tidbits.

Our bodily insult du jour is frozen honey, and it’s exploding all over TikTok … and a few other places. “The hashtag ‘#FrozenHoney’ has been viewed nearly 600 million times, and the hashtag ‘#FrozenHoneyChallenge’ has been viewed more than 80 million times,” NBC News recently reported.

After a few hours in the freezer, honey can be squeezed out of a plastic bottle as a semisolid, toothpastelike goo – it’s stiff enough to rise out of a container that’s pointed straight up – and bitten off in large chunks. And therein lies the problem.

Some people are overdoing it. “Honey is great, but having it in small amounts to sweeten is really a healthy relationship with food, and using it to get a lot of followers and a lot of attention and having it in excess amounts is crazy,” Kristin Kirkpatrick, a registered dietitian at the Cleveland Clinic, told NBC.

Besides the possible weight gain from eating massive amounts of sugar, experts warned that “gobbling up bottles of frozen honey” could lead to stomach cramping, bloating, and diarrhea. Some TikTokers, NBC noted, said that they “were running for the bathroom.”

As we said, it’s a trend that is exploding.

Be sure to tune in next week, when we learn how TikTokers use ground meat as a skin moisturizer.

Bother me, I’m working 

Although some of us have been comfortably functioning in a virtual work environment, others are now trickling back into the office. And you know what that means? People come to your desk to show you pictures of their cat or tell you about their kid’s birthday party. You may sneer at the interruption, but a study shows you actually like it.

A team of researchers at the University of Cincinnati surveyed 111 full-time employees twice a day for 3 weeks about their work experience. They asked about mental exhaustion, workplace interruptions, sense of belonging, and overall job satisfaction. They found that employees had a higher sense of belonging and job satisfaction when interrupted with a social versus work interruption.

“Interruptions can actually benefit individuals from an interpersonal perspective – people feel like they belong when others come and talk to them or ask them questions, even while being distracted from their tasks,” said Heather C. Vough, senior investigator and a former university faculty member.

Chitchatting at work is often seen as a distraction, but this study suggests that it’s not like heating up fish in the breakroom microwave.

So the next time someone hits you with the “Hey, do you have a sec?,” do yourself a favor and enjoy the interruption.
 

A smorgasbord of science

It’s probably difficult to recruit patients for some medical trials. Try this new drug and potentially get all sorts of interesting and unpleasant side effects. Pass. We suggest the approach a group of researchers from the University of Kansas took for a recent study into weight gain: Invite a bunch of 20-something adults to an all-you-can-eat buffet. They’ll be beating down your door in no time.

Their study, published in Appetite, focused on hyperpalatable food – the sort of food you can keep eating – and compared it with high-energy-dense food and ultra processed food. The test patients had their body composition measured, were let loose on the buffet, and were measured again a year later.

The patients who favored salty/carbohydrate-filled hyperpalatable food (such as pretzels or popcorn) were much more likely to gain weight, compared with those who focused on salty/fat-filled food of any variety. As a matter of fact, those who stuck to fatty food during the buffet had no change in weight over the 1-year study period. The researchers noted that those who ate the carb-filled food tended more toward hedonic eating, or the act of eating simply for pleasure.

The study is no doubt helpful in the long battle against obesity and overeating, but it’s also a very helpful guide to getting the most bang for your buck at the buffet. Stay away from the cheap salty snack food. Go for the steak and seafood. Get your money’s worth. In the long run you won’t even gain any weight. No promises about tomorrow though.
 

There’s a cheat code for that

For a large percentage of kids and young adults, and maybe even older adults (we don’t judge), a storm warning means a cozy night in playing video games. Staying inside is probably the safest bet when there’s a storm, and the weatherman never says to avoid playing video games when there’s lightning.

Maybe he should, though, since a man from Tennessee reportedly got struck by lightning through his game controller. Emergency crews determined that lightning either hit the man’s house or struck near it and went through the controller. The type of console was not revealed, even though some people may want to know the specifics before playing during the next storm.

Luckily, the man was not seriously hurt and did not need to go to the hospital. This is apparently not unheard of, as a professional gamer was shocked through a wired controller last year, causing burns on her hands and a broken controller.

This might be our cue to do less electrical types of activities during thunderstorms, like knitting or reading by candlelight.
 

Freeze, squeeze, and enjoy … cramping

As you were ingesting last week’s installment of the never-ending buffet that is LOTME, you probably wondered: What’s going on? Where’s the latest bodily insult being perpetuated by the gang over at TikTok?

Have no fear, good readers. We would never make you go 2 straight weeks without serving up some hyperpalatable TikTok tidbits.

Our bodily insult du jour is frozen honey, and it’s exploding all over TikTok … and a few other places. “The hashtag ‘#FrozenHoney’ has been viewed nearly 600 million times, and the hashtag ‘#FrozenHoneyChallenge’ has been viewed more than 80 million times,” NBC News recently reported.

After a few hours in the freezer, honey can be squeezed out of a plastic bottle as a semisolid, toothpastelike goo – it’s stiff enough to rise out of a container that’s pointed straight up – and bitten off in large chunks. And therein lies the problem.

Some people are overdoing it. “Honey is great, but having it in small amounts to sweeten is really a healthy relationship with food, and using it to get a lot of followers and a lot of attention and having it in excess amounts is crazy,” Kristin Kirkpatrick, a registered dietitian at the Cleveland Clinic, told NBC.

Besides the possible weight gain from eating massive amounts of sugar, experts warned that “gobbling up bottles of frozen honey” could lead to stomach cramping, bloating, and diarrhea. Some TikTokers, NBC noted, said that they “were running for the bathroom.”

As we said, it’s a trend that is exploding.

Because the Delta variant of SARS-CoV-2 spreads more easily than the original virus, the proportion of the population that needs to be vaccinated to reach herd immunity could be upward of 80% or more, experts say.

Also, it could be time to consider wearing an N95 mask in public indoor spaces regardless of vaccination status, according to a media briefing on Aug. 3 sponsored by the Infectious Diseases Society of America.

Furthermore, giving booster shots to the fully vaccinated is not the top public health priority now. Instead, third vaccinations should be reserved for more vulnerable populations – and efforts should focus on getting first vaccinations to unvaccinated people in the United States and around the world.

“The problem here is that the Delta variant is ... more transmissible than the original virus. That pushes the overall population herd immunity threshold much higher,” Ricardo Franco, MD, assistant professor of medicine at the University of Alabama at Birmingham, said during the briefing.

“For Delta, those threshold estimates go well over 80% and may be approaching 90%,” he said.

To put that figure in context, the original SARS-CoV-2 virus required an estimated 67% of the population to be vaccinated to achieve herd immunity. Also, measles has one of the highest herd immunity thresholds at 95%, Dr. Franco added.

Herd immunity is the point at which enough people are immunized that the entire population gains protection. And it’s already happening. “Unvaccinated people are actually benefiting from greater herd immunity protection in high-vaccination counties compared to low-vaccination ones,” he said.
 

Maximize mask protection

Unlike early in the COVID-19 pandemic with widespread shortages of personal protective equipment, face masks are now readily available. This includes N95 masks, which offer enhanced protection against SARS-CoV-2, Ezekiel J. Emanuel, MD, PhD, said during the briefing.

Following the July 27 CDC recommendation that most Americans wear masks indoors when in public places, “I do think we need to upgrade our masks,” said Dr. Emanuel, who is Diane v.S. Levy & Robert M. Levy professor at the University of Pennsylvania, Philadelphia.

“It’s not just any mask,” he added. “Good masks make a big difference and are very important.”

Mask protection is about blocking 0.3-mcm particles, “and I think we need to make sure that people have masks that can filter that out,” he said. Although surgical masks are very good, he added, “they’re not quite as good as N95s.” As their name implies, N95s filter out 95% of these particles.

Dr. Emanuel acknowledged that people are tired of COVID-19 and complying with public health measures but urged perseverance. “We’ve sacrificed a lot. We should not throw it away in just a few months because we are tired. We’re all tired, but we do have to do the little bit extra getting vaccinated, wearing masks indoors, and protecting ourselves, our families, and our communities.”
 

Dealing with a disconnect

In response to a reporter’s question about the possibility that the large crowd at the Lollapalooza music festival in Chicago could become a superspreader event, Dr. Emanuel said, “it is worrisome.”

“I would say that, if you’re going to go to a gathering like that, wearing an N95 mask is wise, and not spending too long at any one place is also wise,” he said.

On the plus side, the event was held outdoors with lots of air circulation, Dr. Emanuel said.

However, “this is the kind of thing where we’ve got a sort of disconnect between people’s desire to get back to normal ... and the fact that we’re in the middle of this upsurge.”

Another potential problem is the event brought people together from many different locations, so when they travel home, they could be “potentially seeding lots of other communities.”
 

Boosters for some, for now

Even though not officially recommended, some fully vaccinated Americans are seeking a third or booster vaccination on their own.

Asked for his opinion, Dr. Emanuel said: “We’re probably going to have to be giving boosters to immunocompromised people and people who are susceptible. That’s where we are going to start.”

More research is needed regarding booster shots, he said. “There are very small studies – and the ‘very small’ should be emphasized – given that we’ve given shots to over 160 million people.”

“But it does appear that the boosters increase the antibodies and protection,” he said.

Instead of boosters, it is more important for people who haven’t been vaccinated to get fully vaccinated.

“We need to put our priorities in the right places,” he said.

Emanuel noted that, except for people in rural areas that might have to travel long distances, access to vaccines is no longer an issue. “It’s very hard not to find a vaccine if you want it.”

A remaining hurdle is “battling a major disinformation initiative. I don’t think this is misinformation. I think there’s very clear evidence that it is disinformation – false facts about the vaccines being spread,” Dr. Emanuel said.
 

The breakthrough infection dilemma

Breakthrough cases “remain the vast minority of infections at this time ... that is reassuring,” Dr. Franco said.

Also, tracking symptomatic breakthrough infections remains easier than studying fully vaccinated people who become infected with SARS-CoV-2 but remain symptom free.

“We really don’t have a good handle on the frequency of asymptomatic cases,” Dr. Emanuel said. “If you’re missing breakthrough infections, a lot of them, you may be missing some [virus] evolution that would be very important for us to follow.” This missing information could include the emergence of new variants.

The asymptomatic breakthrough cases are the most worrisome group,” Dr. Emanuel said. “You get infected, you’re feeling fine. Maybe you’ve got a little sneeze or cough, but nothing unusual. And then you’re still able to transmit the Delta variant.”
 

The big picture

The upsurge in cases, hospitalizations, and deaths is a major challenge, Dr. Emanuel said. “We need to address that by getting many more people vaccinated right now with what are very good vaccines.”

“But it also means that we have to stop being U.S. focused alone.” He pointed out that Delta and other variants originated overseas, “so getting the world vaccinated ... has to be a top priority.”

“We are obviously all facing a challenge as we move into the fall,” Dr. Emanuel said. “With schools opening and employers bringing their employees back together, even if these groups are vaccinated, there are going to be major challenges for all of us.”

Low dose acetylsalicylic acid (LDASA) may have some protective benefit against cognitive decline, but only if started well before symptoms begin, according to a retrospective analysis of two large cohorts. The association with all-cause dementia was weak, but much more pronounced in subjects with coronary heart disease.

The results underscore that individuals with cardiovascular disease risk factors should be prescribed LDASA, and they should be encouraged to be compliant. The study differed from previous observational and randomized, controlled trials, which yielded mixed results. Many looked at individuals older than age 65. The pathological changes associated with dementia may occur up to 2 decades before symptom onset, and it appears that LDASA cannot counter cognitive decline after a diagnosis is made. “The use of LDASA at this age may be already too late,” said Thi Ngoc Mai Nguyen, a PhD student at Network Aging Research, Heidelberg University, Germany. She presented the results at the 2021 Alzheimer’s Association International Conference.

Previous studies also included individuals using LDASA to prevent cardiovascular disease, and they didn’t always adjust for these risk factors. The current work used two large databases, UK Biobank and ESTHER, with a follow-up time of over 10 years for both. “We were able to balance out the distribution of measured baseline covariates (to be) similar between LDASA users and nonusers, and thus, we were able to adjust for confounders more comprehensively,” said Ms. Nguyen.
 

Not yet a definitive answer

Although the findings are promising, Ms. Nguyen noted that the study is not the final word. “Residual confounding is possible, and causation cannot be tested. The only way to answer this is to have clinical trials with at least 10 years of follow-up,” said Ms. Nguyen. She plans to conduct similar studies in non-White populations, and also to examine whether LDASA can help preserve cognitive function in middle-age adults.

The study is interesting, said Claire Sexton, DPhil, who was asked to comment, but she suggested that it is not practice changing. “There is not evidence from the dementia science perspective that should go against whatever the recommendations are for cardiovascular risk,” said Dr. Sexton, director of scientific programs and outreach at the Alzheimer’s Association. “I don’t think this study alone can provide a definitive answer on low-dose aspirin and its association with dementia and Alzheimer’s disease, but it’s an important addition to the literature,” she added.
 

Meta-analysis data

The researchers examined two prospective cohort studies, and combined them into a meta-analysis. It included the ESTHER cohort from Saarland, Germany, with 5,258 individuals and 14.3 years of follow-up, and the UK Biobank cohort, with 305,394 individuals and 11.6 years of follow-up. Subjects selected for analysis were 55 years old or older.

The meta-analysis showed no significant association between LDASA use and reduced risk of Alzheimer’s disease, but there was an association between LDASA use and all-cause dementia (hazard ratio [HR], 0.96; 95% confidence interval [CI], 0.93-0.99).

There were no sex differences with respect to Alzheimer’s dementia, but in males, LDASA was associated with lower risk of vascular dementia (HR, 0.85; 95% CI, 0.79-0.93) and all-cause dementia (HR, 0.87; 95% CI, 0.83-0.92). However, in females, LDASA was tied to greater risk of both vascular dementia (HR, 1.13; 95% CI, 1.02-1.24) and all-cause dementia (HR, 1.07; 95% CI, 1.02-1.13).

The strongest association between LDASA and reduced dementia risk was found in subjects with coronary heart disease (HR, 0.69; 95% CI, 0.59-0.80).

The researchers also used UK Biobank primary care data to analyze associations between longer use of LDASA and reduced dementia risk. Those who used LDASA for 0-5 years were at a higher than average risk of all-cause dementia (HR, 2.80; 95% CI, 2.48-3.16), Alzheimer’s disease (HR, 2.26; 95% CI, 1.84-2.77), and vascular dementia (HR, 3.79; 95% CI, 3.17-4.53). Long-term LDASA users, defined as 10 years or longer, had a lower risk of all-cause dementia (HR, 0.51; 95% CI, 0.47-0.56), Alzheimer’s disease (HR, 0.58; 95% CI, 0.51-0.68), and vascular dementia (HR, 0.48; 95% CI, 0.42-0.56).

Dr. Nguyen and Dr. Sexton have no relevant financial disclosures.

Low dose acetylsalicylic acid (LDASA) may have some protective benefit against cognitive decline, but only if started well before symptoms begin, according to a retrospective analysis of two large cohorts. The association with all-cause dementia was weak, but much more pronounced in subjects with coronary heart disease.

The results underscore that individuals with cardiovascular disease risk factors should be prescribed LDASA, and they should be encouraged to be compliant. The study differed from previous observational and randomized, controlled trials, which yielded mixed results. Many looked at individuals older than age 65. The pathological changes associated with dementia may occur up to 2 decades before symptom onset, and it appears that LDASA cannot counter cognitive decline after a diagnosis is made. “The use of LDASA at this age may be already too late,” said Thi Ngoc Mai Nguyen, a PhD student at Network Aging Research, Heidelberg University, Germany. She presented the results at the 2021 Alzheimer’s Association International Conference.

Previous studies also included individuals using LDASA to prevent cardiovascular disease, and they didn’t always adjust for these risk factors. The current work used two large databases, UK Biobank and ESTHER, with a follow-up time of over 10 years for both. “We were able to balance out the distribution of measured baseline covariates (to be) similar between LDASA users and nonusers, and thus, we were able to adjust for confounders more comprehensively,” said Ms. Nguyen.
 

Not yet a definitive answer

Although the findings are promising, Ms. Nguyen noted that the study is not the final word. “Residual confounding is possible, and causation cannot be tested. The only way to answer this is to have clinical trials with at least 10 years of follow-up,” said Ms. Nguyen. She plans to conduct similar studies in non-White populations, and also to examine whether LDASA can help preserve cognitive function in middle-age adults.

The study is interesting, said Claire Sexton, DPhil, who was asked to comment, but she suggested that it is not practice changing. “There is not evidence from the dementia science perspective that should go against whatever the recommendations are for cardiovascular risk,” said Dr. Sexton, director of scientific programs and outreach at the Alzheimer’s Association. “I don’t think this study alone can provide a definitive answer on low-dose aspirin and its association with dementia and Alzheimer’s disease, but it’s an important addition to the literature,” she added.
 

Meta-analysis data

The researchers examined two prospective cohort studies, and combined them into a meta-analysis. It included the ESTHER cohort from Saarland, Germany, with 5,258 individuals and 14.3 years of follow-up, and the UK Biobank cohort, with 305,394 individuals and 11.6 years of follow-up. Subjects selected for analysis were 55 years old or older.

The meta-analysis showed no significant association between LDASA use and reduced risk of Alzheimer’s disease, but there was an association between LDASA use and all-cause dementia (hazard ratio [HR], 0.96; 95% confidence interval [CI], 0.93-0.99).

There were no sex differences with respect to Alzheimer’s dementia, but in males, LDASA was associated with lower risk of vascular dementia (HR, 0.85; 95% CI, 0.79-0.93) and all-cause dementia (HR, 0.87; 95% CI, 0.83-0.92). However, in females, LDASA was tied to greater risk of both vascular dementia (HR, 1.13; 95% CI, 1.02-1.24) and all-cause dementia (HR, 1.07; 95% CI, 1.02-1.13).

The strongest association between LDASA and reduced dementia risk was found in subjects with coronary heart disease (HR, 0.69; 95% CI, 0.59-0.80).

The researchers also used UK Biobank primary care data to analyze associations between longer use of LDASA and reduced dementia risk. Those who used LDASA for 0-5 years were at a higher than average risk of all-cause dementia (HR, 2.80; 95% CI, 2.48-3.16), Alzheimer’s disease (HR, 2.26; 95% CI, 1.84-2.77), and vascular dementia (HR, 3.79; 95% CI, 3.17-4.53). Long-term LDASA users, defined as 10 years or longer, had a lower risk of all-cause dementia (HR, 0.51; 95% CI, 0.47-0.56), Alzheimer’s disease (HR, 0.58; 95% CI, 0.51-0.68), and vascular dementia (HR, 0.48; 95% CI, 0.42-0.56).

Like many colleagues, I have been working to change the minds and behaviors of acquaintances and patients who are opting to forgo a COVID vaccine. The large numbers of these unvaccinated Americans, combined with the surging Delta coronavirus variant, are endangering the health of us all.

When I spoke with the 22-year-old daughter of a family friend about what was holding her back, she told me that she would “never” get vaccinated. I shared my vaccination experience and told her that, except for a sore arm both times for a day, I felt no side effects. Likewise, I said, all of my adult family members are vaccinated, and everyone is fine. She was neither moved nor convinced.

Finally, I asked her whether she attended school (knowing that she was a college graduate), and she said “yes.” So I told her that all 50 states require children attending public schools to be vaccinated for diseases such as diphtheria, tetanus, polio, and the chickenpox – with certain religious, philosophical, and medical exemptions. Her response was simple: “I didn’t know that. Anyway, my parents were in charge.” Suddenly, her thinking shifted. “You’re right,” she said. She got a COVID shot the next day. Success for me.

When I asked another acquaintance whether he’d been vaccinated, he said he’d heard people were getting very sick from the vaccine – and was going to wait. Another gentleman I spoke with said that, at age 45, he was healthy. Besides, he added, he “doesn’t get sick.” When I asked another acquaintance about her vaccination status, her retort was that this was none of my business. So far, I’m batting about .300.

But as a physician, I believe that we – and other health care providers – must continue to encourage the people in our lives to care for themselves and others by getting vaccinated. One concrete step advised by the Centers for Disease Control and Prevention is to help people make an appointment for a shot. Some sites no longer require appointments, and New York City, for example, offers in-home vaccinations to all NYC residents.

Also, NYC Mayor Bill de Blasio announced Aug. 3 the “Key to NYC Pass,” which he called a “first-in-the-nation approach” to vaccination. Under this new policy, vaccine-eligible people aged 12 and older in New York City will need to prove with a vaccination card, an app, or an Excelsior Pass that they have received at least one dose of vaccine before participating in indoor venues such as restaurants, bars, gyms, and movie theaters within the city. Mayor de Blasio said the new initiative, which is still being finalized, will be phased in starting the week of Aug. 16. I see this as a major public health measure that will keep people healthy – and get them vaccinated.

The medical community should support this move by the city of New York and encourage people to follow CDC guidance on wearing face coverings in public settings, especially schools. New research shows that physicians continue to be among the most trusted sources of vaccine-related information.

Another strategy we might use is to point to the longtime practices of surgeons. We could ask: Why do surgeons wear face masks in the operating room? For years, these coverings have been used to protect patients from the nasal and oral bacteria generated by operating room staff. Likewise, we can tell those who remain on the fence that, by wearing face masks, we are protecting others from all variants, but specifically from Delta – which the CDC now says can be transmitted by people who are fully vaccinated.

Why did the CDC lift face mask guidance for fully vaccinated people in indoor spaces in May? It was clear to me and other colleagues back then that this was not a good idea. Despite that guidance, I continued to wear a mask in public places and advised anyone who would listen to do the same.

The development of vaccines in the 20th and 21st centuries has saved millions of lives. The World Health Organization reports that 4 million to 5 million lives a year are saved by immunizations. In addition, research shows that, before the emergence of SARS-CoV-2, vaccinations led to the eradication of smallpox and polio, and a 74% drop in measles-related deaths between 2004 and 2014.
 

Protecting the most vulnerable

With COVID cases surging, particularly in parts of the South and Midwest, I am concerned about children under age 12 who do not yet qualify for a vaccine. Certainly, unvaccinated parents could spread the virus to their young children, and unvaccinated children could transmit the illness to immediate and extended family. Now that the CDC has said that there is a risk of SARS-CoV-2 breakthrough infection among fully vaccinated people in areas with high community transmission, should we worry about unvaccinated young children with vaccinated parents? I recently spoke with James C. Fagin, MD, a board-certified pediatrician and immunologist, to get his views on this issue.

Dr. Fagin, who is retired, said he is in complete agreement with the Food and Drug Administration when it comes to approving medications for children. However, given the seriousness of the pandemic and the need to get our children back to in-person learning, he would like to see the approval process safely expedited. Large numbers of unvaccinated people increase the pool for the Delta variant and could increase the likelihood of a new variant that is more resistant to the vaccines, said Dr. Fagin, former chief of academic pediatrics at North Shore University Hospital and a former faculty member in the allergy/immunology division of Cohen Children’s Medical Center, both in New York.

Meanwhile, I agree with the American Academy of Pediatrics’ recommendations that children, teachers, and school staff and other adults in school settings should wear masks regardless of vaccination status. Kids adjust well to masks – as my grandchildren and their friends have.

The bottom line is that we need to get as many people as possible vaccinated as soon as possible, and while doing so, we must continue to wear face coverings in public spaces. As clinicians, we have a special responsibility to do all that we can to change minds – and behaviors.

In announcing new guidance on July 27, the CDC said vaccinated people should wear face masks in indoor public places with “high” or “substantial” community transmission rates of COVID-19.

Data from the CDC shows that designation covers 69.3% of all counties in the United States – 52.2% (1,680 counties) with high community transmission rates and 17.1% (551 counties) with substantial rates.

A county has “high transmission” if it reports 100 or more weekly cases per 100,000 residents or a 10% or higher test positivity rate in the last 7 days, the CDC said. “Substantial transmission” means a county reports 50-99 weekly cases per 100,000 residents or has a positivity rate between 8% and 9.9% in the last 7 days.

About 23% of U.S. counties had moderate rates of community transmission, and 7.67% had low rates.

Smithsonian requiring masks again

The Smithsonian now requires all visitors over age 2, regardless of vaccination status, to wear face masks indoors and in all museum spaces.

The Smithsonian said in a news release that fully vaccinated visitors won’t have to wear masks at the National Zoo or outdoor gardens for museums.

The new rule goes into effect Aug. 6. It reverses a rule that said fully vaccinated visitors didn’t have to wear masks indoors beginning June 28.

Indoor face masks will be required throughout the District of Columbia beginning July 31., D.C. Mayor Muriel Bowser.
 

House Republicans protest face mask policy

About 40 maskless Republican members of the U.S. House of Representatives filed onto the Senate floor on July 29 to protest a new rule requiring House members to wear face masks, the Hill reported.

Congress’s attending doctor said in a memo that the 435 members of the House, plus workers, must wear masks indoors, but not the 100 members of the Senate. The Senate is a smaller body and has had better mask compliance than the House.

Rep. Ronny Jackson (R-Tex.), told the Hill that Republicans wanted to show “what it was like on the floor of the Senate versus the floor of the House. Obviously, it’s vastly different.”

Among the group of Republicans who filed onto the Senate floor were Rep. Lauren Boebert of Colorado, Rep. Matt Gaetz and Rep. Byron Donalds of Florida, Rep. Marjorie Taylor Greene of Georgia, Rep. Chip Roy and Rep. Louie Gohmert of Texas, Rep. Madison Cawthorn of North Carolina, Rep. Warren Davidson of Ohio, and Rep. Andy Biggs of Arizona.

An incidental diagnosis of intracranial atherosclerotic stenosis in stroke-free individuals should trigger a thorough assessment of vascular health, according to the authors of a study identifying risk factors and vascular event risk in asymptomatic ICAS.

mr.suphachai praserdumrongchai/iStock/Getty Images Plus

That conclusion emerged from data collected on more than 1,000 stroke-free participants in NOMAS (Northern Manhattan Study), a trial that prospectively followed participants who underwent a brain magnetic resonance angiogram (MRA) during 2003-2008.

In ICAS patients with stenosis of at least 70%, even with aggressive medical therapy, the annual stroke recurrence rate is 10%-20% in those with occlusions and at least three or more vascular risk factors. This high rate of recurrent vascular events in patients with stroke caused by ICAS warrants greater focus on primary prevention and targeted interventions for stroke-free individuals at highest risk for ICAS-related events, the investigators concluded.
 

Identify high-risk ICAS

Using NOMAS data, the investigators, led by Jose Gutierrez, MD, MPH, tested the hypothesis that stroke-free subjects at high risk of stroke and vascular events could be identified through the presence of asymptomatic ICAS. NOMAS is an ongoing, population-based epidemiologic study among randomly selected people with home telephones living in northern Manhattan.

During 2003-2008, investigators invited participants who were at least 50 years old, stroke free, and without contraindications to undergo brain MRA. The 1,211 study members were followed annually via telephone and in-person adjudication of events. A control group of 79 patients with no MRA was also identified with similar rates of hypertension, diabetes, hypercholesterolemia and current smoking.

Mean age was about 71 years (59% female, 65% Hispanic, 45% any stenosis). At the time of MRA, 78% had hypertension, 25% had diabetes, 81% had hypercholesterolemia, and 11% were current smokers.

Researchers rated stenoses in 11 brain arteries as 0, with no stenosis; 1, with less than 50% stenosis or luminal irregularities; 2, 50%-69% stenosis; and 3, at least 70% stenosis or flow gap. Outcomes included vascular death, myocardial infarction, ischemic stroke, cardioembolic stroke, intracranial artery disease stroke (which combined intracranial small and large artery disease strokes), and any vascular events (defined as a composite of vascular death, any stroke, or MI).
 

Greater stenosis denotes higher risk

Analysis found ICAS to be associated with older age (odds ratio, 1.02 per year; 95% confidence interval, 1.01-1.04), hypertension duration (OR, 1.01 per year; 95% CI, 1.00-1.02), higher number of glucose-lowering drugs (OR, 1.64 per each medication; 95% CI, 1.24-2.15), and HDL cholesterol(OR, 0.96 per mg/dL; 95% CI, 0.92-0.99). Event risk was greater among participants with ICAS of at least 70% (5.5% annual risk of vascular events; HR, 2.1; 95% CI, 1.4-3.2; compared with those with no ICAS), the investigators reported in the Journal of the American College of Cardiology.

Furthermore, 80% of incident strokes initially classified as small artery disease occurred among individuals with evidence of any degree of ICAS at their baseline MRI, the investigators noted. They found also that individuals with ICAS who had a primary care physician at the time of their initial MRI had a lower risk of events. Frequent primary care visits, they observed, might imply greater control of risk factors and other unmeasured confounders, such as health literacy, health care trust, access, and availability.
 

Incidental ICAS should trigger vascular assessment

An incidental diagnosis of ICAS in stroke-free subjects should trigger a thorough assessment of vascular health, the investigators concluded. They commented also that prophylaxis of first-ever stroke at this asymptomatic stage “may magnify the societal benefits of vascular prevention and decrease stroke-related disability and vascular death in our communities.”

“The big gap in our knowledge,” Tanya N. Turan, MD, professor of neurology at Medical University of South Carolina, Charleston, wrote in an accompanying editorial “is understanding the pathophysiological triggers for an asymptomatic stenosis to become a high-risk symptomatic stenosis. Until that question is answered, screening for asymptomatic ICAS is unlikely to change management among patients with known vascular risk factors.” In an interview, she observed further that “MRI plaque imaging could be a useful research tool to see if certain plaque features in an asymptomatic lesion are high risk for causing stroke. If that were proven, then it would make more sense to screen for ICAS and develop specific therapeutic strategies targeting high-risk asymptomatic plaque.”
 

Focus on recurrent stroke misplaced

Dr. Gutierrez said in an interview: “In the stroke world, most of what we do focuses on preventing recurrent stroke. Nonetheless, three-fourths of strokes in this country are new strokes, so to me it doesn’t make much sense to spend most of our efforts and attention to prevent the smallest fractions of strokes that occur in our society.”

He stressed that “the first immediate application of our results is that if people having a brain MRA for other reasons are found to have incidental, and therefore asymptomatic, ICAS, then they should be aggressively treated for vascular risk factors.” Secondly, “we hope to identify the patients at the highest risk of prevalent ICAS before they have a stroke. Among them, a brain MRI/MRA evaluating the phenotype would determine how aggressively to treat LDL.”

Dr. Gutierrez, professor of neurology at Columbia University Irving Medical Center, New York, noted that educating patients of their underlying high risk of events may have the effect of engaging them more in their own care. “There is evidence that actually showing people scans increases compliance and health literacy. It’s not yet standard of care, but we hope our future projects will help advance the field in the primary prevention direction,” he said.

That conclusion emerged from data collected on more than 1,000 stroke-free participants in NOMAS (Northern Manhattan Study), a trial that prospectively followed participants who underwent a brain magnetic resonance angiogram (MRA) during 2003-2008.

In ICAS patients with stenosis of at least 70%, even with aggressive medical therapy, the annual stroke recurrence rate is 10%-20% in those with occlusions and at least three or more vascular risk factors. This high rate of recurrent vascular events in patients with stroke caused by ICAS warrants greater focus on primary prevention and targeted interventions for stroke-free individuals at highest risk for ICAS-related events, the investigators concluded.
 

Identify high-risk ICAS

Using NOMAS data, the investigators, led by Jose Gutierrez, MD, MPH, tested the hypothesis that stroke-free subjects at high risk of stroke and vascular events could be identified through the presence of asymptomatic ICAS. NOMAS is an ongoing, population-based epidemiologic study among randomly selected people with home telephones living in northern Manhattan.

During 2003-2008, investigators invited participants who were at least 50 years old, stroke free, and without contraindications to undergo brain MRA. The 1,211 study members were followed annually via telephone and in-person adjudication of events. A control group of 79 patients with no MRA was also identified with similar rates of hypertension, diabetes, hypercholesterolemia and current smoking.

Mean age was about 71 years (59% female, 65% Hispanic, 45% any stenosis). At the time of MRA, 78% had hypertension, 25% had diabetes, 81% had hypercholesterolemia, and 11% were current smokers.

Researchers rated stenoses in 11 brain arteries as 0, with no stenosis; 1, with less than 50% stenosis or luminal irregularities; 2, 50%-69% stenosis; and 3, at least 70% stenosis or flow gap. Outcomes included vascular death, myocardial infarction, ischemic stroke, cardioembolic stroke, intracranial artery disease stroke (which combined intracranial small and large artery disease strokes), and any vascular events (defined as a composite of vascular death, any stroke, or MI).

Sleep patterns may influence risk of dementia, even decades before the onset of symptoms, according to a new analysis of data from the Whitehall II cohort study.

Previous work had identified links between short sleep duration and dementia risk, but few studies examined sleep habits long before onset of dementia. Those that did produced inconsistent results, according to Séverine Sabia, PhD, who is a research associate at Inserm (France) and the University College London.

“One potential reason for these inconstancies is the large range of ages of the study populations, and the small number of participants within each sleep duration group. The novelty of our study is to examine this association among almost 8,000 participants with a follow-up of 30 years, using repeated measures of sleep duration starting in midlife to consider sleep duration at specific ages,” Dr. Sabia said in an interview. She presented the research at the 2021 Alzheimer’s Association International Conference.

Those previous studies found a U-shaped association between sleep duration and dementia risk, with lowest risk associated with 7-8 hours of sleep, but greater risk for shorter and longer durations. However, because the studies had follow-up periods shorter than 10 years, they are at greater risk of reverse causation bias. Longer follow-up studies tended to have small sample sizes or to focus on older adults.

The longer follow-up in the current study makes for a more compelling case, said Claire Sexton, DPhil, director of Scientific Programs & Outreach for the Alzheimer’s Association. Observations of short or long sleep closer to the onset of symptoms could just be a warning sign of dementia. “But looking at age 50, age 60 ... if you’re seeing those relationships, then it’s less likely that it is just purely prodromal,” said Dr. Sexton. But it still doesn’t necessarily confirm causation. “It could also be a risk factor,” Dr. Sexton added.
 

Multifactorial risk

Dr. Sabia also noted that the magnitude of risk was similar to that seen with smoking or obesity, and many factors play a role in dementia risk. “Even if the risk of dementia was 30% higher in those with persistent short sleep duration, in absolute terms, the percentage of those with persistent short duration who developed dementia was 8%, and 6% in those with persistent sleep duration of 7 hours. Dementia is a multifactorial disease, which means that several factors are likely to influence its onset. Sleep duration is one of them, but if a person has poor sleep and does not manage to increase it, there are other important prevention measures. It is important to keep a healthy lifestyle and cardiometabolic measures in the normal range. All together it is likely to be beneficial for brain health in later life,” she said.

Dr. Sexton agreed. “With sleep we’re still trying to tease apart what aspect of sleep is important. Is it the sleep duration? Is it the quality of sleep? Is it certain sleep stages?” she said.

Regardless of sleep’s potential influence on dementia risk, both Dr. Sexton and Dr. Sabia noted the importance of sleep for general health. “These types of problems are very prevalent, so it’s good for people to be aware of them. And then if they notice any problems with their sleep, or any changes, to go and see their health care provider, and to be discussing them, and then to be investigating the cause, and to see whether changes in sleep hygiene and treatments for insomnia could address these sleep problems,” said Dr. Sexton.
 

Decades of data

During the Whitehall II study, researchers assessed average sleep duration (“How many hours of sleep do you have on an average weeknight?”) six times over 30 years of follow-up. Dr. Sabia’s group extracted self-reported sleep duration data at ages 50, 60, and 70. Short sleep duration was defined as fewer than 5 hours, or 6 hours. Normal sleep duration was defined as 7 hours. Long duration was defined as 8 hours or more.

A questioner during the Q&A period noted that this grouping is a little unusual. Many studies define 7-8 hours as normal. Dr. Sabia answered that they were unable to examine periods of 9 hours or more due to the nature of the data, and the lowest associated risk was found at 7 hours.

The researchers analyzed data from 7,959 participants (33.0% women). At age 50, compared with 7 hours of sleep, 6 or few hours of sleep was associated with a higher risk of dementia over the ensuing 25 years of follow-up (hazard ratio [HR], 1.22; 95% confidence interval [CI], 1.01-1.48). The same was true at age 60 (15 years of follow-up HR, 1.37; 95% CI, 1.10-1.72). There was a trend at age 70 (8 years follow-up; HR, 1.24; 95% CI, 0.98-1.57). For 8 or more hours of sleep, there were trends toward increased risk at age 50 (HR, 1.25; 95% CI, 0.98-1.60). Long sleep at age 60 and 70 was associated with heightened risk, but the confidence intervals were well outside statistical significance.

Twenty percent of participants had persistent short sleep over the course of follow-up, 37% had persistent normal sleep, and 7% had persistent long sleep. Seven percent of participants experienced a change from normal sleep to short sleep, 16% had a change from short sleep to normal sleep, and 13% had a change from normal sleep to long sleep.

Persistent short sleep between age 50 and 70 was associated with a 30% increased risk of dementia (HR, 1.30; 95% CI, 1.00-1.69). There were no statistically significant associations between dementia risk and any of the changing sleep pattern groups.

Physicians wearing white coats were rated as significantly more experienced and professional than peers wearing casual attire. Regardless of their attire, however, female physicians were more likely to be judged as appearing less professional and were more likely to be misidentified as medical technicians, physician assistants, or nurses, found research published in JAMA Network Open.

“A white coat with scrubs attire was most preferred for surgeons (mean preference index, 1.3), whereas a white coat with business attire was preferred for family physicians and dermatologists (mean preference indexes, 1.6 and 1.2, respectively; P < .001),” Helen Xun, MD, Johns Hopkins University, Baltimore, and colleagues wrote. “A male model wearing business inner wear with a white coat, fleece jacket, or softshell jacket was perceived as significantly more professional than a female model wearing the same attire (mean professionalism score: male, 65.8; female, 56.2; mean difference in professionalism score: white coat, 12.06; fleece, 7.89; softshell, 8.82; P < .001). ... A male model wearing hospital scrubs or fashion scrubs alone was also perceived as more professional than a female model in the same attire.”

While casual attire, such as fleece or softshell jackets emblazoned with the names of the institution and wearer, has become more popular attire for physicians in recent years, the researchers noted theirs is the first published research to identify associations between gender, attire, and how people distinguish between various health care roles. The study authors launched their web-based survey from May to June 2020 and asked people aged 18 years and older to rate a series of photographs of deidentified models wearing health care attire. Inner wear choices were business attire versus scrubs with and without outer wear options of a long white coat, gray fleece jacket, or black softshell jackets. Survey respondents ranked the images on a 6-point Likert scale with 1 being the least experienced, professional, and friendly and 6 being the most experienced, professional, and friendly. Survey respondents also viewed individual images of male or female models and were asked to rate their professionalism on a scale of 0-100 – with 100 as the “most professional” as well as to identify their profession as either physician, surgeon, nurse, medical technician, or physician assistant.

The study team included 487 (93.3%) of 522 completed surveys in their analyses. Respondents’ mean age was 36.2 years; 260 (53.4%) were female; 372 (76.4%) were White; 33 (6.8%) were Black or African American. Younger respondents and those living in the Western United States who had more exposure to physician casual attire appeared more accepting of it, the authors wrote.

“I remember attending my white-coat ceremony as a medical student, and the symbolism of it all representing me entering the profession. It felt very emotional and heavy and I felt very proud to be there. I also remember taking a ‘selfie’ in my long white coat as a doctor for the first time before my first shift as a resident. But, I’ve also been wearing that same white coat, and a large badge with a ‘DOCTOR’ label on it, and been mistaken by a patient or parent for something other than the physician,” Alexandra M. Sims, a pediatrician and health equity researcher in Cincinnati, said in an interview. “So, I’d really hope that the take-home here is not simply that we must wear our white coats to be considered more professional. I think we have to unpack and dismantle how we’ve even built this notion of ‘professionalism’ in the first place. Women, people of color, and other marginalized groups were certainly not a part of the defining, but we must be a part of the reimagining of an equitable health care profession in this new era.”

As sartorial trends usher in more casual attire, clinicians should redouble efforts to build rapport and enhance communication with patients, such as clarifying team members’ roles when introducing themselves. Dr. Xun and coauthors noted that addressing gender bias is important for all clinicians – not just women – and point to the need for institutional and organizational support for disciplines where gender bias is “especially prevalent,” like surgery. “This responsibility should not be undertaken only by the individuals that experience the biases, which may result in additional cumulative career disadvantages. The promotion of equality and diversity begins with recognition, characterization, and evidence-supported interventions and is a community operation,” Dr. Xun and colleagues concluded.

“I do not equate attire to professionalism or experience, nor is it connected to my satisfaction with the physician. For myself and my daughter, it is the experience of care that ultimately influences our perceptions regarding the professionalism of the physician,” Hala H. Durrah, MTA, parent to a chronically ill child with special health care needs and a Patient and Family Engagement Consultant, said in an interview. “My respect for a physician will ultimately be determined by how my daughter and I were treated, not just from a clinical perspective, but how we felt during those interactions.”

Physicians wearing white coats were rated as significantly more experienced and professional than peers wearing casual attire. Regardless of their attire, however, female physicians were more likely to be judged as appearing less professional and were more likely to be misidentified as medical technicians, physician assistants, or nurses, found research published in JAMA Network Open.

The following is not anything I’m doing. It’s written solely as a thought exercise.

What if I refused to see unvaccinated patients in my office?

I don’t think it’s illegal, any more than if I refused to see smokers, or gum chewers. I mean, it’s my practice. I’m the only one here.

It’s certainly unethical, though. Part of being a doctor is caring for those who need our help. I’m vaccinated, so hopefully I’m at lower risk of getting sick if exposed. But that’s not a guarantee.

The vaccine is 95% effective. But that still means 1 in 20 vaccinated people can still contract the disease. Of course, people who aren’t vaccinated have no protection at all, aside from their immune system.

If the decision to not vaccinate, or not wear a mask, only affected themselves, I wouldn’t have as much of an issue with it. Like bungee jumping, the consequences of something going wrong affect only the person who made the choice (not including costs to the health care system or loved ones, now caretakers).

But with an easily spread infectious disease, a better analogy is probably that of drunk drivers. Their actions affect not only themselves, but everyone else on (or near) the road: other drivers, their passengers, pedestrians. ...

In a neurology practice not all of my patients have great immune systems. Sure, there are healthy migraine patients, but I also see patients with multiple sclerosis (on drugs like Ocrevus), patients with myasthenia gravis (on steroids or Imuran), and other folks whose survival depends on keeping their immune systems working at a suboptimal level. Not to mention those with malignancies, leukemias, and lymphomas.

These people have no real defense against the virus, and many of them can’t even get the vaccine. They depend on precautions, herd immunity, and luck. So, to protect them, maybe I should keep the unvaccinated out. Granted, this isn’t a guarantee, either, and doesn’t protect them during more mundane activities, such as grocery shopping or filling up their car.

Besides, the unvaccinated have their own, unrelated, neurological issues. Migraines, seizures, neuropathy, and so they need to see me. My job is to help anyone who needs me. Isn’t that what being a doctor is all about?

It’s an interesting question. Like most things in medicine, there is no black or white, just different shades of gray.
