About one-third of U.S. adults struggled with medical debt during the pandemic, according to data from a Commonwealth Fund survey released July 16.

Despite the passage of four major relief bills in 2020 and 2021 and federal efforts to offset pandemic- and job-related coverage loss, many people continued to face financial challenges, especially those with a low income and those who are Black or Latino.

The survey, which included responses from 5,450 adults, revealed that 10% of adults aged 19-64 were uninsured during the first half of 2021, a rate lower than what was recorded in 2020 and 2019 in both federal and private surveys. However, uninsured rates were highest among those with low income, those younger than 50 years old, and Black and Latino adults.

For most adults who lost employee health insurance, the coverage gap was relatively brief, with 54% saying their coverage gap lasted 3-4 months. Only 16% of adults said coverage gaps lasted a year or longer.

“The good news is that this survey is suggesting that the coverage losses during the pandemic may have been offset by federal efforts to help people get and maintain health insurance coverage,” lead author Sara Collins, PhD, Commonwealth Fund vice president for health care coverage, access, and tracking, said in an interview.

“The bad news is that a third of Americans continue to struggle with medical bills and medical debt, even among those who have health insurance coverage,” Dr. Collins added.

Indeed, the survey found that about one-third of insured adults reported a medical bill problem or that they were paying off medical debt, as did approximately half of those who were uninsured. Medical debt caused 35% of respondents to use up most or all of their savings to pay it off.

Meanwhile, 27% of adults said medical bills left them unable to pay for necessities such as food, heat, or rent. What surprised Dr. Collins was that 43% of adults said they received a lower credit rating as a result of their medical debt, and 35% said they had taken on more credit card debt to pay off these bills.

“The fact that it’s bleeding over into people’s financial security in terms of their credit scores, I think is something that really needs to be looked at by policymakers,” Dr. Collins said.

When analyzed by race/ethnicity, the researchers found that 55% of Black adults and 44% of Latino/Hispanic adults reported medical bills and debt problems, compared with 32% of White adults. In addition, 47% of those living below the poverty line also reported problems with medical bills.

According to the survey, 45% of respondents were directly affected by the pandemic in at least one of three ways – testing positive or getting sick from COVID-19, losing income, or losing employer coverage – with Black and Latinx adults and those with lower incomes at greater risk.

George Abraham, MD, president of the American College of Physicians, said the Commonwealth Fund’s findings were not surprising because it has always been known that underrepresented populations struggle for access to care because of socioeconomic factors. He said these populations were more vulnerable in terms of more severe infections and disease burden during the pandemic.

“[This study] validates what primary care physicians have been saying all along in regard to our patients’ access to care and their ability to cover health care costs,” said Dr. Abraham, who was not involved with the study. “This will hopefully be an eye-opener and wake-up call that reiterates that we still do not have equitable access to care and vulnerable populations are disproportionately affected.”

He believes that, although people are insured, many of them may contend with medical debt when they fall ill because they can’t afford the premiums.

“Even though they may have been registered for health coverage, they may not have active coverage at the time of illness simply because they weren’t able to make their last premium payments because they’ve been down, because they lost their job, or whatever else,” Dr. Abraham explained. “On paper, they appear to have health care coverage. But in reality, clearly, that coverage does not match their needs or it’s not affordable.”

For Dr. Abraham, the study emphasizes the need to continue support for health care reform, including pricing it so that insurance is available for those with fewer socioeconomic resources.

Yalda Jabbarpour, MD, medical director of the Robert Graham Center for Policy Studies, Washington, said high-deductible health plans need to be “reined in” because they can lead to greater debt, particularly among vulnerable populations.

“Hopefully this will encourage policymakers to look more closely at the problem of medical debt as a contributing factor to financial instability,” Dr. Jabbarpour said. “Federal relief is important, so is expanding access to comprehensive, affordable health care coverage.”

Dr. Collins said there should also be a way to raise awareness of the health care marketplace and coverage options so that people have an easier time getting insured.

Adult women with acne describe significant impacts on their lived experience of acne, including concerns about appearance, mental and emotional health consequences, and disruption to their personal and professional lives, results from a qualitative study demonstrated.

“Nearly 50% of women experience acne in their 20s, and 35% experience acne in their 30s,” the study’s corresponding author, John S. Barbieri, MD, MBA, formerly of the department of dermatology at the University of Pennsylvania, Philadelphia, told this news organization. “While several qualitative studies have examined acne in adolescence, the lived experience of adult female acne has not been explored in detail and prior studies have included relatively few patients. As a result, we conducted a series of semistructured interviews among adult women with acne to examine the lived experience of adult acne and its treatment.”

For the study, published online July 28, 2021, in JAMA Dermatology, Dr. Barbieri and colleagues conducted voluntary, confidential phone interviews with 50 women aged between 18 and 40 years with moderate to severe acne who were recruited from the University of Pennsylvania Health System and from a private dermatology clinic in Cincinnati. They used free listing and open-ended, semistructured interviews to elicit opinions from the women on how acne affected their lives; their experience with acne treatments, dermatologists, and health care systems; as well as their views on treatment success.

The mean age of the participants was 28 years and 48% were white (10% were Black, 8% were Asian, 4% were more than one race, and the rest abstained from answering this question; 10% said they were Hispanic).

More than three-quarters (78%) reported prior treatment with topical retinoids, followed by spironolactone (70%), topical antibiotics (43%), combined oral contraceptives (43%), and isotretinoin (41%). During the free-listing part of interviews, where the women reported the first words that came to their mind when asked about success of treatment and adverse effects, the most important terms expressed related to treatment success were clear skin, no scarring, and no acne. The most important terms related to treatment adverse effects were dryness, redness, and burning.

In the semistructured interview portion of the study, the main themes expressed were acne-related concerns about appearance, including feeling less confident at work; mental and emotional health, including feelings of depression, anxiety, depression, and low self-worth during acne breakouts; and everyday life impact, including the notion that acne affected how other people perceived them. The other main themes included successful treatment, with clear skin and having a manageable number of lesions being desirable outcomes; and interactions with health care, including varied experiences with dermatologists. The researchers observed that most participants did not think oral antibiotics were appropriate treatments for their acne, specifically because of limited long-term effectiveness.

“Many patients described frustration with finding a dermatologist with whom they were comfortable and with identifying effective treatments for their acne,” the authors wrote. “In contrast, those who thought their dermatologist listened to their concerns and individualized their treatment plan reported higher levels of satisfaction.”

In an interview, Dr. Barbieri, who is now with the department of dermatology at Brigham and Women’s Hospital, Boston, said that he was surprised by how many patients expressed interest in nonantibiotic treatments for acne, “given that oral antibiotics are by far the most commonly prescribed systemic treatment for acne.”

Moreover, he added, “although I have experienced many patients being hesitant about isotretinoin, I was surprised by how strong patients’ concerns were about isotretinoin side effects. Unfortunately, there are many misconceptions about isotretinoin that limit use of this treatment that can be highly effective and safe for the appropriate patient.”

In an accompanying editorial, dermatologists Diane M. Thiboutot, MD and Andrea L. Zaenglein, MD, with Penn State University, Hershey, and Alison M. Layton, MB, ChB, with the Harrogate Foundation Trust, Harrogate, North Yorkshire, England, wrote that the findings from the study “resonate with those recently reported in several international studies that examine the impacts of acne, how patients assess treatment success, and what is important to measure from a patient and health care professional perspective in a clinical trial for acne.”

A large systematic review on the impact of acne on patients, conducted by the Acne Core Outcomes Research Network (ACORN), found that “appearance-related concerns and negative psychosocial effects were found to be a major impact of acne,” they noted. “Surprisingly, only 22 of the 473 studies identified in this review included qualitative data gathered from patient interviews. It is encouraging to see the concordance between the concerns voiced by the participants in the current study and those identified from the literature review, wherein a variety of methods were used to assess acne impacts.”

For his part, Dr. Barbieri said that the study findings “justify the importance of having a discussion with patients about their unique lived experience of acne and individualizing treatment to their specific needs. Patient reported outcome measures could be a useful adjunctive tool to capture these impacts on quality of life.”

This study was funded by grant from the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Dr. Barbieri disclosed that he received partial salary support through a Pfizer Fellowship in Dermatology Patient Oriented Research grant to the Trustees of the University of Pennsylvania. Dr. Thiboutot reported receiving consultant fees from Galderma and Novartis outside the submitted work. Dr. Layton reported receiving unrestricted educational presentation, advisory board, and consultancy fees from Galderma Honoraria; unrestricted educational presentation and advisory board honoraria from Leo; advisory board honoraria from Novartis and Mylan; consultancy honoraria from Procter and Gamble and Meda; grants from Galderma; and consultancy and advisory board honoraria from Origimm outside the submitted work.

Plasma biomarkers such as amyloid-beta 40 and 42, phosphorylated tau 181 and 217, and neurofilament light hold great promise for diagnosing and determining a prognosis for Alzheimer’s disease. Such tests are likely to be widely available in the near future.

But work remains to be done to translate findings from academic studies to the more general population. A key consideration is that plasma levels of these biomarkers could be affected by other conditions, which could in turn skew test results, according to Michelle Mielke, PhD, who spoke on the topic at the 2021 Alzheimer’s Association International Conference.

“The markers, which we’ve published on as well, look really promising. But they have primarily been looked at in more specialty clinics or memory clinics, and have not been examined in the general community. The goal of this presentation was really just to take a look at this in the community, in older individuals that have multiple comorbidities, and to understand what factors might affect the levels of these markers. Because as we do go forward and develop cut points, we are going to have to consider these aspects,” said Dr. Mielke in an interview. She is a professor of epidemiology and neurology at the Mayo Clinic in Rochester, Minn.
 

Case in point

To illustrate the point, Dr. Mielke presented data from her group, which analyzed P-tau 181 and P-tau 217 data from 1,329 Mayo clinic patients. Of that total, 1,161 were cognitively unimpaired (CU), 153 had mild cognitive impairment (MCI), and 15 had dementia. The median age was 67, 55% were male, and 26% had the APOE e4 allele.

After adjustment for age and sex, there were statistically significantly elevated levels of both biomarkers among patients who had tested positive for amyloid and patients who had had a stroke or myocardial infarction, and in the presence of chronic kidney disease (CKD). There also was a trend towards an increase of biomarker levels with increasing body mass index. The differences remained even after the analysis was restricted to individuals who were amyloid negative.

The researchers then looked more closely at the impact of CKD, stroke, and MI on P-tau cut points and the ability to predict abnormal amyloid positron emission tomography (PET) scans. They defined an abnormal range as 1.96 standard deviation units beyond the mean among amyloid-negative individuals who are cognitively impaired. They excluded subjects with those risk factors and then established new cut points in the absence of the factors. The approach led to a significant change for the cutoff of P-tau 181 values, from 1.57 pg/mL or greater for individuals without stroke, MI, or CKD, and 1.75 pg/mL or greater for individuals with one such factor. There was little difference in the cutoff value for P-tau 217, from 0.25 pg/mL to 0.26 pg/mL.

Among people without a history of stroke, MI, or CKD, a P-tau 181 cutoff of 1.57 pg/mL or greater had an area under the receiving operating characteristic (AUROC) value of 0.717 (95% confidence interval, 0.691-0.744), compared with an AUROC of 0.687 (95% CI, 0.662-0.712) at a cutoff of 1.75 pg/mL or greater among people with those conditions. For P-tau 217, the values were 0.737 pg/mL (95% CI, 0.712-0.762) and 0.724 pg/mL (95% CI, 0.699-0.748), respectively.

“The sensitivity was better when they excluded those individuals with these conditions. Specificity was slightly, but not significantly, lower,” said Dr. Mielke during her talk.
 

Other considerations

Dr. Mielke added that it will be important to account for these and other factors when applying biomarkers in community settings, but they should also be considered in the context of health care disparities. Stroke, MI, and CKD are more common in African Americans, for example, suggesting that there could be racial differences in biomarker levels, though she said the difference in biomarker levels would be more likely attributable to the underlying comorbidities than race per se. “As shown, these factors can affect the consideration of an accuracy of cut points for clinical use. So I think future discussions will be needed as to how best to determine the cut points, and how to base them off of (different) populations,” said Dr. Mielke.

These sorts of refinements are important, according to Christopher Weber, PhD, who was asked for comment. “We have learned the importance of an early and accurate diagnosis. The blood test is a biomarker that does detect the hallmarks of Alzheimer’s disease sometimes up to decades before symptoms even appear,” said Dr. Weber, who is director of Global Science Initiatives at the Alzheimer’s Association.

But “there’s a lot more that we need to learn regarding when exactly to use them, who they’re appropriate for. And I think validation is the key to these blood biomarkers,” Dr. Weber added.

Dr. Mielke has been a consultant with the Brain Protection Company and Biogen. Dr. Weber has no relevant financial disclosures.

Plasma biomarkers such as amyloid-beta 40 and 42, phosphorylated tau 181 and 217, and neurofilament light hold great promise for diagnosing and determining a prognosis for Alzheimer’s disease. Such tests are likely to be widely available in the near future.

But work remains to be done to translate findings from academic studies to the more general population. A key consideration is that plasma levels of these biomarkers could be affected by other conditions, which could in turn skew test results, according to Michelle Mielke, PhD, who spoke on the topic at the 2021 Alzheimer’s Association International Conference.

“The markers, which we’ve published on as well, look really promising. But they have primarily been looked at in more specialty clinics or memory clinics, and have not been examined in the general community. The goal of this presentation was really just to take a look at this in the community, in older individuals that have multiple comorbidities, and to understand what factors might affect the levels of these markers. Because as we do go forward and develop cut points, we are going to have to consider these aspects,” said Dr. Mielke in an interview. She is a professor of epidemiology and neurology at the Mayo Clinic in Rochester, Minn.
 

Case in point

To illustrate the point, Dr. Mielke presented data from her group, which analyzed P-tau 181 and P-tau 217 data from 1,329 Mayo clinic patients. Of that total, 1,161 were cognitively unimpaired (CU), 153 had mild cognitive impairment (MCI), and 15 had dementia. The median age was 67, 55% were male, and 26% had the APOE e4 allele.

After adjustment for age and sex, there were statistically significantly elevated levels of both biomarkers among patients who had tested positive for amyloid and patients who had had a stroke or myocardial infarction, and in the presence of chronic kidney disease (CKD). There also was a trend towards an increase of biomarker levels with increasing body mass index. The differences remained even after the analysis was restricted to individuals who were amyloid negative.

The researchers then looked more closely at the impact of CKD, stroke, and MI on P-tau cut points and the ability to predict abnormal amyloid positron emission tomography (PET) scans. They defined an abnormal range as 1.96 standard deviation units beyond the mean among amyloid-negative individuals who are cognitively impaired. They excluded subjects with those risk factors and then established new cut points in the absence of the factors. The approach led to a significant change for the cutoff of P-tau 181 values, from 1.57 pg/mL or greater for individuals without stroke, MI, or CKD, and 1.75 pg/mL or greater for individuals with one such factor. There was little difference in the cutoff value for P-tau 217, from 0.25 pg/mL to 0.26 pg/mL.

Among people without a history of stroke, MI, or CKD, a P-tau 181 cutoff of 1.57 pg/mL or greater had an area under the receiving operating characteristic (AUROC) value of 0.717 (95% confidence interval, 0.691-0.744), compared with an AUROC of 0.687 (95% CI, 0.662-0.712) at a cutoff of 1.75 pg/mL or greater among people with those conditions. For P-tau 217, the values were 0.737 pg/mL (95% CI, 0.712-0.762) and 0.724 pg/mL (95% CI, 0.699-0.748), respectively.

“The sensitivity was better when they excluded those individuals with these conditions. Specificity was slightly, but not significantly, lower,” said Dr. Mielke during her talk.

Researchers have identified clusters of blood-based metabolites, molecules produced by cells during metabolism, that appear to predict subsequent dementia risk in new findings that may provide a prevention target.

Investigators found one of the clusters includes small high-density lipoprotein (HDL) metabolites associated with vascular dementia, while another cluster involves ketone bodies and citrate that are primarily associated with Alzheimer’s disease.

Ketone bodies, or ketones, are three related compounds – acetone, acetoacetic acid, and beta-hydroxybutyric acid (BHB) – produced by the liver during fat metabolism. Citrate is a salt or ester of citric acid.

Weight loss before dementia explained?

For the study, investigators included 125,000 patients from the UK Biobank, which includes 51,031 who were over age 60 at baseline. Of these, 1,188 developed dementia during a follow-up of about 10 years; 553 were diagnosed with Alzheimer’s disease and 298 with vascular dementia.

Researchers used a platform that covers 249 metabolic measures, including small molecules, fatty acids, and lipoprotein lipids.

They estimated risk associated with these metabolites, adjusting for age, sex, body mass index, technical variables, ethnicity, smoking, alcohol, education, metabolic and neuropsychiatric medication, and APOE4 genotypes.

Of the 249 metabolites, 47 (19%) were associated with dementia risk in those over age 60, after adjustment.

The investigators examined effect estimates for associations of metabolites with both Alzheimer’s disease and vascular dementia over age 60 versus hippocampal volume under age 60. They found a “very strong, very significant” association for Alzheimer’s disease, and a “marginally significant” association for vascular dementia, said Dr. van Duijn.

This would be expected, as there is a much stronger correlation between hippocampal and Alzheimer’s disease versus vascular dementia, she added.

“We not only see that the metabolites predict dementia, but also early pathology. This makes these findings rather interesting for targeting prevention,” she said. An analysis of total brain volume showed “very strong, very similar, very significant associations” for both Alzheimer’s disease and vascular dementia,” added Dr. van Duijn.

The researchers found a major shift in various metabolites involved in energy metabolism in the 10-year period before the diagnosis of Alzheimer’s disease. These changes include low levels of branched-chain amino acids and omega-3 fatty acids and high levels of glucose, citrate, acetone, beta-hydroxybutyrate, and acetate. “This finding is in line with that in APOE models that show reduced energy metabolism over age in the brain,” said Dr. van Duijn.

She added that high levels of some of these metabolites are associated with low body weight before dementia onset, which may explain the weight loss seen in patients before developing the disease. “Our hypothesis is that the liver is burning the fat reserves of the patients in order to provide the brain with fuel,” she explained.
 

Diet a prevention target?

The results also showed ketone bodies increase with age, which may represent the aging brain’s “compensation mechanism” to deal with an energy shortage, said Dr. van Duijn. “Supplementation of ketone bodies, branched-chain amino and omega-3 fatty acids may help support brain function.”

The fact that ketone bodies were positively associated with the risk of dementia is “a very important finding,” she said.

Following this and other presentations, session cochair Rima Kaddurah-Daouk, PhD, professor in psychiatry and behavioral sciences, Institute for Brain Sciences, Duke University, Durham, N.C., noted the research is “an important part of trying to decipher some of the mysteries in Alzheimer’s disease.”

The research contributes to the understanding of how nutrition and diet could influence metabolism and then the brain and is “opening the horizon” for thinking about “strategies for therapeutic interventions,” she said.

The study received funding support from the National Institute on Aging. The investigators have reported no relevant financial relationships.

Around the world, cases of dementia are projected to hit 153 million in 2050, up from around 57 million in 2019, new global prevalence data show. “These extreme increases are due largely to demographic trends, including population growth and aging,” said study investigator Emma Nichols, MPH, a researcher at the Institute for Health Metrics and Evaluation at the University of Washington in Seattle.

“Our estimates of expected increases can and should inform policy and planning efforts that will be needed to address the needs of the growing number of individuals with dementia in the future,” Ms. Nichols said.

The latest global prevalence data were reported at the 2021 Alzheimer’s Association International Conference.

“The numbers are staggering: Nearly 153 million cases of dementia are predicted worldwide by the year 2050. To put that in context, that number is equal to approximately half of the U.S. population in 2020,” Heather M. Snyder, PhD, vice president of medical and scientific relations for the Alzheimer’s Association, said in a statement.
 

Prevalence by country

To more accurately forecast global dementia prevalence and produce country-level estimates, the investigators leveraged data from 1999 to 2019 from the Global Burden of Disease study, a comprehensive set of estimates of worldwide health trends.

These data suggest global dementia cases will increase from 57.4 million (50.4 to 65.1) in 2019 to 152.8 million (130.8 to 175.9) in 2050.

Regions that will experience the worst of the increase are eastern Sub-Saharan Africa, North Africa, and the Middle East.

The researchers also factored into the forecasts expected trends in obesity, diabetes, smoking, and educational attainment.

Increases in better education around the world are projected to decrease dementia prevalence by 6.2 million cases worldwide by 2050. However, anticipated trends in smoking, high body mass index, and diabetes will offset this gain, increasing global dementia cases by 6.8 million cases.

“A reversal of these expected trends in cardiovascular risks would be necessary to alter the anticipated trends,” Ms. Nichols said. “Interventions targeted at modifiable risk factors for dementia represent a viable strategy to help address the anticipated trends in dementia burden,” she added.
 

Need for effective prevention, treatment

Commenting on the research, Rebecca M. Edelmayer, PhD, senior director of scientific engagement at the Alzheimer’s Association, said the global increase in dementia cases is something the association has been following for many years. “We know that if we do not find effective treatments that are going to stop, slow, or prevent Alzheimer’s disease, this number will continue to grow and it will continue to impact people globally,” Dr. Edelmayer said.

She noted that although there are some positive trends, including the fact that increased education may drive down dementia risk, other factors, such as smoking, high body mass index, and high blood sugar level, are predicted to increase in prevalence.

“Some of these factors are actually counterbalancing each other, and in the end, if we don’t continue to develop culturally tailored interventions or even risk reduction strategies for individuals across the globe, we will continue to see those numbers rise overall,” Dr. Edelmayer said.

With COVID, the fun never ends

Welcome to America’s favorite pandemic-themed game show! Let’s play Covidiot Proof! And now, here’s your host, the lovely and talented Anthony Grouchy!

sabelskaya/iStock/Getty Images Plus

Tony: Hello everyone! Our first category today is America or [blank], and the first clue is for you, Don. This country requires “individuals to use a health pass to patronize indoor establishments such as restaurants, bars, nightclubs and cinemas.”

Don: Freedom-loving Americans would never stand for that, Tony, so I’m going to say Greece.

Tony: That’s correct, Don. One hundred points for you. Okay Joe, here’s your clue: In this country, some people wear disguises to get a COVID vaccination so their friends and families won’t find out.

Joe: Sounds like communism to me, Tony. I’ll say Cuba.

Tony: Sorry Joe, that’s incorrect. Don?

Don: The friends and families sound like freedom-loving Americans, so it must be America.

Tony: It is America. Missouri, to be exact. And now, one last question for both of you to win the game. True or false? Did the pastor of a church in Tennessee say that mask-wearers would be kicked out of the building because “I am not playing these Democrat games up in this church”?

Joe: That’s fake news, Tony. It’s gotta be false.

Tony: Incorrect! It’s absolutely true. That means today’s winner is … Joe? Yes, I’m being told that Tennessee goes to Joe.

Don: That’s bulls#&@! I won this thing! I’ll see you in court!
 

More money, more life

Does it seem to you that the wealthy live forever, while the less financially comfortable live shorter lives? If you answered, yes, it turns out that you’re right.

Researchers analyzed the effect of net worth at midlife with mortality. To take out genetic differences among the sample of 5,400 adults aged 46 years, the investigators also studied a subset of 2,490 twin and sibling pairs.

“The within-family association provides strong evidence that an association between wealth accumulation and life expectancy exists, because comparing siblings within the same family to each other controls for all of the life experience and biology that they share,” said coauthor Eric Finegood of Northwestern University, Chicago.

But what if one sibling has a history of cancer, heart disease, or other health conditions? The cost of treatment and employment limitations could affect someone’s ability to stack their wealth, right? Absolutely. The researchers took that into account and looked at only healthy individuals and found the same results. More money, longer life.

We have the policies and programs in place for heart health, diabetes prevention, and smoking cessation, as they are seen as major threats to public health. So why not do the same for financial security? A low bank account may just be more harmful.
 

Holding the ‘health care and wellness’ gun

Cigarettes are not good for us. We know this.

It’s, therefore, not surprising to learn that a business has requested for a U.K. ban on the sale of cigarettes by 2030. However, when that someone turns out to be the CEO of Philip Morris International, tobacco company and maker of Marlboro cigarettes, things get a little confusing.

Banning cigarettes, according to Jacek Olczak, would reduce confusion among consumers, many of whom feel that the alternatives are worse for their health. His company can “see the world without cigarettes ... and actually, the sooner it happens, the better it is for everyone.” A truly noble sentiment from the CEO of a large tobacco company. Nothing nefarious going on here.

Philip Morris International is actually leaning hard into nonsmoking means of tobacco consumption, even going so far as to brand itself a “health care and wellness company” on a mission to “unsmoke the world.” And if those aren’t egregious business euphemisms, we don’t know what is.

Of course, for all the completely believable and sincere rhetoric, the fact is that Marlboros are still on the shelves. Philip Morris is still making and advertising them. If their concern was genuine, why wouldn’t they just stop manufacturing them now?

So, we ask ourselves if this a selfless act of kindness or is it an unscrupulous corporate act to get a leg up on their competitors? We’ll leave it up to the readers to decide.

Okay, we lied, it’s the second one.
 

Autopsy of the living dead

Imagine the absolute terror you’d feel if you opened your eyes to bright, blinding white lights only to see a bone saw 3 inches from your forehead and getting closer by the second. Horrifying for you, certainly, but think about the poor pathologist behind the saw who probably thought a zombie apocalypse was coming. This was close to being a reality for a 29-year-old prisoner at the Asturias Central Penitentiary in Spain.

Gonzalo Montoya Jiménez was discovered in his cell unresponsive. Three physicians examined him and found he was showing signs of death, such as cyanosis and rigor mortis. Mr. Jiménez was processed like any other body and was sent, in a body bag, to a hospital mortuary, where he spent time in a freezer for body preservation. Just before he was due for his autopsy, he began showing signs of life.

It’s not completely clear why this happened to poor Mr. Jiménez, but it was reported that he wasn’t feeling well the day before and that he has epilepsy. Hospital officials suggested he may have been cataleptic, possibly because he had trouble adhering to his medication schedule.

Mr. Jiménez was moved to another hospital under armed guard after coming back to life and regained consciousness after a day or so. Talk about cheating death.

Tony: Hello everyone! Our first category today is America or [blank], and the first clue is for you, Don. This country requires “individuals to use a health pass to patronize indoor establishments such as restaurants, bars, nightclubs and cinemas.”

Don: Freedom-loving Americans would never stand for that, Tony, so I’m going to say Greece.

Tony: That’s correct, Don. One hundred points for you. Okay Joe, here’s your clue: In this country, some people wear disguises to get a COVID vaccination so their friends and families won’t find out.

Joe: Sounds like communism to me, Tony. I’ll say Cuba.

Tony: Sorry Joe, that’s incorrect. Don?

Don: The friends and families sound like freedom-loving Americans, so it must be America.

Tony: It is America. Missouri, to be exact. And now, one last question for both of you to win the game. True or false? Did the pastor of a church in Tennessee say that mask-wearers would be kicked out of the building because “I am not playing these Democrat games up in this church”?

Joe: That’s fake news, Tony. It’s gotta be false.

Tony: Incorrect! It’s absolutely true. That means today’s winner is … Joe? Yes, I’m being told that Tennessee goes to Joe.

Don: That’s bulls#&@! I won this thing! I’ll see you in court!

Drinking six or more cups of coffee per day is associated with smaller brain volume and a 53% increased risk for dementia compared with light coffee consumption (1-2 cups per day), according to the results of a large study.

“With coffee intake, moderation is the key, and especially high levels of consumption may have adverse long-term effects on the brain,” said study investigator Elina Hypponen, PhD, professor of nutritional and genetic epidemiology and director of the Australian Center for Precision Health at the University of South Australia.

“These new data are concerning, and there is a need to conduct further carefully controlled studies to clarify the effects of coffee on the brain.”

The study was published online June 24 in Nutritional Neuroscience.
 

Potent stimulant

Coffee is a potent nervous system stimulant and is among the most popular nonalcoholic beverages. Some previous research suggests it benefits the brain, but the investigators noted that other research shows a negative or U-shaped relationship.

To investigate, the researchers examined data from the U.K. Biobank, a long-term prospective epidemiologic study of more than 500,000 participants aged 37-73 years who were recruited in 22 assessment centers in the United Kingdom between March 2006 and October 2010.

During the baseline assessment, information was gathered using touchscreen questionnaires, verbal interviews, and physical examinations that involved collection of blood, urine, and saliva samples. An imaging substudy was incorporated in 2014, the goal of which was to conduct brain, heart, and body MRI imaging for 100,000 participants.

The investigators conducted analyses on disease outcomes for 398,646 participants for whom information on habitual coffee consumption was available. Brain volume analyses were conducted in 17,702 participants for whom valid brain imaging data were available.

Participants reported coffee intake in cups per day. Researchers grouped coffee consumption into seven categories: nondrinkers, decaffeinated coffee drinkers, and caffeinated coffee drinkers who consumed less than 1 cup/d, 1-2 cups/d, 3-4 cups/d, 5-6 cups/d, and more than 6 cups/d.

The reference category was those who consumed 1-2 cups/d, rather than those who abstained from coffee, because persons who abstain are more likely to be at suboptimal health.

“Comparing the health of coffee drinkers to the health of those choosing to abstain from coffee will typically lead to an impression of a health benefit, even if there would not be one,” said Dr. Hypponen.

The researchers obtained total and regional brain volumes from the MRI imaging substudy starting 4-6 years after baseline assessment. They accessed information on incident dementia and stroke using primary care data, hospital admission electronic health records, national death registers, and self-reported medical conditions.

Covariates included socioeconomic, health, and other factors, such as smoking, alcohol and tea consumption, physical activity, stressful life events, and body mass index.

The investigators found that there was a linear inverse association between coffee consumption and total brain volume (fully adjusted beta per cup, –1.42; 95% confidence interval, –1.89 to –0.94), with consistent patterns for gray matter, white matter, and hippocampal volumes.

There was no evidence to support an association with white matter hyperintensity (WMH) volume (beta –0.01; 95% CI, –0.07 to 0.05).
 

Higher consumption, higher risk

The analysis also revealed a nonlinear association between coffee consumption and the odds of dementia (P nonlinearity = .0001), with slightly higher odds seen with non–coffee drinkers and decaffeinated-coffee drinkers and more notable increases for participants in the highest categories of coffee consumption compared with light coffee drinkers.

After adjustment for all covariates, the odds ratio of dementia among persons in the category of coffee intake was 1.53 (95% CI, 1.28-1.83). After full adjustments, the association with heavy coffee consumption and stroke was not significant, although “we can’t exclude a weak effect,” said Dr. Hypponen.

“For the highest coffee consumption group, the data support an association which may be anywhere from 0% to 37% higher odds of stroke after full adjustment,” she added.

People at risk for hypertension may develop “unpleasant sensations” and stop drinking coffee before a serious adverse event occurs, said Dr. Hypponen. In a previous study, she and her colleagues showed that those who have genetically higher blood pressure tend to drink less coffee than their counterparts without the condition.

“This type of effect might be expected to naturally limit the adverse effects of coffee on the risk of stroke,” said Dr. Hypponen.

The odds remained elevated for participants drinking more than 6 cups/d after the researchers accounted for sleep quality. There were no differences in risk between men and women or by age.

An examination of the consumption of tea, which often contains caffeine, did not show an association with brain volume or the odds of dementia or stroke.

“We don’t know whether the difference between associations seen for coffee and tea intake reflects the difference in related caffeine intake or some other explanation, such as dehydration or effects operating through blood cholesterol,” said Dr. Hypponen.

Although reverse causation is possible, there’s no reason to believe that it is relevant to the study results. Genetic evidence suggests a causal role of higher coffee intake on risk for Alzheimer’s disease. In addition, results of a clinical trial support the association between higher caffeine intake and smaller gray matter volume, said Dr. Hypponen.

The mechanisms linking coffee consumption to brain volumes and dementia are not well established. However, Dr. Hypponen noted that caffeine has been used to induce apoptosis in cancer studies using glial cells.

“Furthermore, adenosine receptors, which mediate many of the effects of caffeine in the brain, have been suggested to influence the release of growth factors, which in turn can have an influence on astrocyte proliferation and angiogenesis in the brain,” she said.

Some types of coffee contain cafestol, which increases blood cholesterol and can have adverse effects though related mechanisms, said Dr. Hypponen.

The mechanism may also involve dehydration, which may have a harmful effect on the brain. The study suggested a correlation between dehydration and high coffee intake. “Of course, if this is the case, it is good news, as then we can do something about it simply by drinking some water every time we have a cup of coffee,” she said.
 

Misleading conclusions

Coffee contains antioxidants, and although previous studies have suggested it might be beneficial, this hypothesis is “too simplistic,” said Dr. Hypponen. “While coffee is not going to be all ‘bad’ either, there are a lot of controversies and suggestions about beneficial effects of coffee which may not be true, or at least do not reflect the full story.”

If the drinking of coffee is at least partly determined by an individual’s health status, then that would often lead to misleading conclusions in observational studies, said Dr. Hypponen.

“When one uses as a comparison people who already have poor health and who do not drink coffee because of that, coffee intake will by default appear beneficial simply because there are more people with disease among those choosing abstinence,” she said.

Before now, there was “very little evidence about the association between coffee intake and brain morphology,” and the studies that were conducted were relatively small, said Dr. Hypponen.

One of these smaller studies included a group of women aged 13-30 years. It found that coffee consumption was not associated with total brain volumes, but the findings suggested a U-shaped association with hippocampal volume; higher values were seen both for nondrinkers and the groups with higher consumption.

A small study of elderly patients with diabetes showed no evidence of an association with white matter volume, but there was a possible age-dependent association with gray matter volume.

The largest of the earlier studies had results that were very similar to those of the current study, suggesting that increasing coffee intake is associated with smaller hippocampal volumes, said Dr. Hypponen.

One of the study’s limitations included the fact that full dietary information was available only for a subsample and that factors such as dehydration were measured at baseline rather than at the time of brain MRI.

Another possible study limitation was the use of self-reported data and the fact that lifestyle changes may have occurred between baseline and MRI or covariate measurement.

In addition, the study is subject to a healthy-volunteer bias, and its implications are restricted to White British persons. The association needs to be studied in other ethnic populations, the authors noted.
 

A reason to cut back?

Commenting on the findings, Walter Willett, MD, DrPH, professor of epidemiology and nutrition, Harvard T. H. Chan School of Public Health, Boston, said the study is large and quite well done.

“It does raise questions about an increase in risk of dementia with six or more cups of coffee per day,” said Dr. Willett. “At the same time, it provides reassurance about lack of adverse effects of coffee for those consuming three or four cups per day, and little increase in risk, if any, with five cups per day.”

It’s not entirely clear whether the increase in risk with six or more cups of coffee per day represents a “true effect” of coffee, inasmuch as the study did not seem to adjust fully for dietary factors, high consumption of alcohol, or past smoking, said Dr. Willett.

The findings don’t suggest that coffee lovers should give up their Java. “But six or more cups per day is a lot, and those who drink that much might consider cutting back a bit while research continues,” said Dr. Willett.

The study was supported by the National Health and Medical Research Council.

To investigate, the researchers examined data from the U.K. Biobank, a long-term prospective epidemiologic study of more than 500,000 participants aged 37-73 years who were recruited in 22 assessment centers in the United Kingdom between March 2006 and October 2010.

During the baseline assessment, information was gathered using touchscreen questionnaires, verbal interviews, and physical examinations that involved collection of blood, urine, and saliva samples. An imaging substudy was incorporated in 2014, the goal of which was to conduct brain, heart, and body MRI imaging for 100,000 participants.

The investigators conducted analyses on disease outcomes for 398,646 participants for whom information on habitual coffee consumption was available. Brain volume analyses were conducted in 17,702 participants for whom valid brain imaging data were available.

Participants reported coffee intake in cups per day. Researchers grouped coffee consumption into seven categories: nondrinkers, decaffeinated coffee drinkers, and caffeinated coffee drinkers who consumed less than 1 cup/d, 1-2 cups/d, 3-4 cups/d, 5-6 cups/d, and more than 6 cups/d.

The reference category was those who consumed 1-2 cups/d, rather than those who abstained from coffee, because persons who abstain are more likely to be at suboptimal health.

“Comparing the health of coffee drinkers to the health of those choosing to abstain from coffee will typically lead to an impression of a health benefit, even if there would not be one,” said Dr. Hypponen.

The researchers obtained total and regional brain volumes from the MRI imaging substudy starting 4-6 years after baseline assessment. They accessed information on incident dementia and stroke using primary care data, hospital admission electronic health records, national death registers, and self-reported medical conditions.

Covariates included socioeconomic, health, and other factors, such as smoking, alcohol and tea consumption, physical activity, stressful life events, and body mass index.

The investigators found that there was a linear inverse association between coffee consumption and total brain volume (fully adjusted beta per cup, –1.42; 95% confidence interval, –1.89 to –0.94), with consistent patterns for gray matter, white matter, and hippocampal volumes.

There was no evidence to support an association with white matter hyperintensity (WMH) volume (beta –0.01; 95% CI, –0.07 to 0.05).
 

Higher consumption, higher risk

The analysis also revealed a nonlinear association between coffee consumption and the odds of dementia (P nonlinearity = .0001), with slightly higher odds seen with non–coffee drinkers and decaffeinated-coffee drinkers and more notable increases for participants in the highest categories of coffee consumption compared with light coffee drinkers.

After adjustment for all covariates, the odds ratio of dementia among persons in the category of coffee intake was 1.53 (95% CI, 1.28-1.83). After full adjustments, the association with heavy coffee consumption and stroke was not significant, although “we can’t exclude a weak effect,” said Dr. Hypponen.

“For the highest coffee consumption group, the data support an association which may be anywhere from 0% to 37% higher odds of stroke after full adjustment,” she added.

People at risk for hypertension may develop “unpleasant sensations” and stop drinking coffee before a serious adverse event occurs, said Dr. Hypponen. In a previous study, she and her colleagues showed that those who have genetically higher blood pressure tend to drink less coffee than their counterparts without the condition.

“This type of effect might be expected to naturally limit the adverse effects of coffee on the risk of stroke,” said Dr. Hypponen.

The odds remained elevated for participants drinking more than 6 cups/d after the researchers accounted for sleep quality. There were no differences in risk between men and women or by age.

An examination of the consumption of tea, which often contains caffeine, did not show an association with brain volume or the odds of dementia or stroke.

“We don’t know whether the difference between associations seen for coffee and tea intake reflects the difference in related caffeine intake or some other explanation, such as dehydration or effects operating through blood cholesterol,” said Dr. Hypponen.

Although reverse causation is possible, there’s no reason to believe that it is relevant to the study results. Genetic evidence suggests a causal role of higher coffee intake on risk for Alzheimer’s disease. In addition, results of a clinical trial support the association between higher caffeine intake and smaller gray matter volume, said Dr. Hypponen.

The mechanisms linking coffee consumption to brain volumes and dementia are not well established. However, Dr. Hypponen noted that caffeine has been used to induce apoptosis in cancer studies using glial cells.

“Furthermore, adenosine receptors, which mediate many of the effects of caffeine in the brain, have been suggested to influence the release of growth factors, which in turn can have an influence on astrocyte proliferation and angiogenesis in the brain,” she said.

Some types of coffee contain cafestol, which increases blood cholesterol and can have adverse effects though related mechanisms, said Dr. Hypponen.

The mechanism may also involve dehydration, which may have a harmful effect on the brain. The study suggested a correlation between dehydration and high coffee intake. “Of course, if this is the case, it is good news, as then we can do something about it simply by drinking some water every time we have a cup of coffee,” she said.
 

Misleading conclusions

Coffee contains antioxidants, and although previous studies have suggested it might be beneficial, this hypothesis is “too simplistic,” said Dr. Hypponen. “While coffee is not going to be all ‘bad’ either, there are a lot of controversies and suggestions about beneficial effects of coffee which may not be true, or at least do not reflect the full story.”

If the drinking of coffee is at least partly determined by an individual’s health status, then that would often lead to misleading conclusions in observational studies, said Dr. Hypponen.

“When one uses as a comparison people who already have poor health and who do not drink coffee because of that, coffee intake will by default appear beneficial simply because there are more people with disease among those choosing abstinence,” she said.

Before now, there was “very little evidence about the association between coffee intake and brain morphology,” and the studies that were conducted were relatively small, said Dr. Hypponen.

One of these smaller studies included a group of women aged 13-30 years. It found that coffee consumption was not associated with total brain volumes, but the findings suggested a U-shaped association with hippocampal volume; higher values were seen both for nondrinkers and the groups with higher consumption.

A small study of elderly patients with diabetes showed no evidence of an association with white matter volume, but there was a possible age-dependent association with gray matter volume.

The largest of the earlier studies had results that were very similar to those of the current study, suggesting that increasing coffee intake is associated with smaller hippocampal volumes, said Dr. Hypponen.

One of the study’s limitations included the fact that full dietary information was available only for a subsample and that factors such as dehydration were measured at baseline rather than at the time of brain MRI.

Another possible study limitation was the use of self-reported data and the fact that lifestyle changes may have occurred between baseline and MRI or covariate measurement.

In addition, the study is subject to a healthy-volunteer bias, and its implications are restricted to White British persons. The association needs to be studied in other ethnic populations, the authors noted.
 

A reason to cut back?

Commenting on the findings, Walter Willett, MD, DrPH, professor of epidemiology and nutrition, Harvard T. H. Chan School of Public Health, Boston, said the study is large and quite well done.

“It does raise questions about an increase in risk of dementia with six or more cups of coffee per day,” said Dr. Willett. “At the same time, it provides reassurance about lack of adverse effects of coffee for those consuming three or four cups per day, and little increase in risk, if any, with five cups per day.”

It’s not entirely clear whether the increase in risk with six or more cups of coffee per day represents a “true effect” of coffee, inasmuch as the study did not seem to adjust fully for dietary factors, high consumption of alcohol, or past smoking, said Dr. Willett.

The findings don’t suggest that coffee lovers should give up their Java. “But six or more cups per day is a lot, and those who drink that much might consider cutting back a bit while research continues,” said Dr. Willett.

The study was supported by the National Health and Medical Research Council.

It’s probably fair to say that most people would like to be thinner. More than 42% of Americans have obesity and another 30% are classified as being overweight, according to the latest statistics from the CDC.

Excess body weight is associated with many illnesses and plays a role in mental health; being heavy can take a toll on self-esteem. Many people worry that carrying excess weight makes them less attractive to potential romantic partners, and both physicians and employers treat those with obesity differently. Furthermore, in psychiatry, many of the medications we prescribe lead to weight gain.

In my clinical practice, I have listened as patients blamed themselves for their body habitus; many won’t consider biological treatments as they feel that would be “cheating” or taking an easy way out. They often point to periods in their life when they did lose weight and believe that they should be able to do it again, even if the weight loss took tremendous effort, was not sustained, and occurred decades ago.

That said, we psychiatrists often find ourselves in the position of managing obesity in our patients. I have been known to give patients who gain weight on antipsychotics either stimulants or metformin, or to add naltrexone to their Wellbutrin (bupropion) to effectively mimic a weight-loss medicine called Contrave. I do think psychiatrists sometimes have an important role in obesity care, an often-overlooked aspect of our profession.
 

Obesity a treatable medical condition

It wasn’t until 2013 that the American Medical Association recognized obesity as a medical condition.

In a New Yorker article that same year, “Diet Drugs Work: Why Won’t Doctors Prescribe Them?” Suzanne Koven wrote: “Several obesity experts told me they’ve encountered doctors who confide that they just didn’t like fat people and don’t enjoy taking care of them. Even doctors who treat obese patients feel stigmatized: ‘diet doctor’ is not a flattering term.”

Eat less, exercise more – with a blame-the-patient attitude – is still what people see as the “right” way to lose weight.

On June 4, 2021, the FDA approved semaglutide, a glucagonlike peptide–1 receptor agonist, previously used for the treatment of diabetes, for use as a weight loss agent for patients with obesity, or for those with a body mass index over 27 kg/m² if they also have a weight-related comorbidity.

Semaglutide has three trade names, all manufactured by Novo Nordisk. The pill version is called Rybelsus and comes in 7-mg and 14-mg tablets. Ozempic is available in 0.5-mg and 1.0-mg doses and is administered weekly by subcutaneous injection for diabetes. The new, higher-dose preparation for weight loss, Wegovy, 2.4 mg, also comes as a weekly subcutaneous dose and is now available for the hefty price of $1,400 per month.

In STEP 1 trials, the higher-dose Wegovy was associated with an average 14.9% weight loss (15.3 kg) over 68 weeks, more than any other single-agent weight loss medication on the market.

GLP-1 receptor agonists work in the brain to decrease appetite, slow gastric emptying, increase insulin secretion, and stimulate brown adipose tissue thermogenesis.
 

Psych drugs lead to weight gain

Elaine Weiner, MD, is the medical director in the outpatient research program of the Maryland Psychiatric Research Center in Catonsville, where she treats patients with schizophrenia.

“Nearly all of our patients gain 20 pounds or more on the combinations of medications we use, mostly atypical antipsychotics,” she said. “Weight management is difficult for people who don’t have problems with motivation, but in our patients, lack of motivation is a core part of their illness, so asking them to adhere to diet and exercise regimens is of limited utility.

“Then, add to that the fact that they sometimes don’t have primary care doctors, and these issues of weight gain and metabolic syndrome come back to the psychiatrist. It is a really bad problem and we need more treatments.”

Fatima Cody Stanford, MD, MPH, MPA,  is a fellowship-trained obesity medicine physician-scientist at the Massachusetts General Hospital Weight Center and Harvard Medical School, both in Boston. She has treated thousands of patients with obesity, speaks internationally on the topic of weight loss medicine, and has published over 100 peer-reviewed articles on obesity.

We spoke at length about recent changes in the field of obesity medicine and the introduction of the new GLP-1 receptor agonists.

“We as physicians have learned so little,” Dr. Stanford said. “This mantra of ‘calories in, calories out’ is not working; this is inaccurate and our focus on this has led to a rise in obesity. All calories are not created the same, and I think we are finally starting to see obesity medicine take off.”

Dr. Stanford is quick to note that obesity is a complex problem. Several different hormones are involved in regulating both appetite and satiety, processed foods promote weight gain, sleep is crucial to weight loss, and exercise helps maintain weight loss but is not usually effective in promoting it. “There are many contributors to energy storage,” she said.

The stimulant phentermine was approved in 1959. Addiction was a concern, and then in the 1990s, it was used in combination with fenfluramine to promote weight loss, a combination known as phen-fen. Fenfluramine was pulled from the market in 1997 when it was found to be associated with pulmonary hypertension and then heart valve abnormalities.

“This frightened quite a few physicians,” Dr. Stanford noted. Phentermine is still used for weight loss, either alone or together with topiramate, as a combination medication called Qsymia, nicknamed phen-top.

“Phen-top is the next best thing we have to semaglutide, and there is an average weight loss of 8%-9% of body weight. Semaglutide is going to be really significant for those people who are responders, and this has been quite well tolerated, the most common side effect being nausea,” she said.

However, she is quick to note that not everyone responds to every medication. “I use each patient’s clinical profile to determine what strategies and which medications to use.”
 

Cardiologists getting in the game

Michael Miller, MD, is a cardiologist at the University of Maryland, Baltimore, and author of “Heal Your Heart” (Emmaus, Pa.: Rodale, 2014). He is very enthusiastic about the approval of semaglutide.

“We are so excited because you finally can use these medicines without having to be diabetic,” Dr. Miller said. “We’re waiting on the results of the SELECT [Semaglutide Effects on Heart Disease and Stroke in Patients With Overweight or Obesity] trials looking at people who are not diabetic or who are prediabetic, to see the 5-year outcomes with regard to cardiac events.

“Usually endocrinologists prescribe these medications, but cardiologists have started to get into the game since GLP-1 receptor agonists reduce cardiovascular events.” Dr. Miller is hopeful that this medication may neutralize the weight gain caused by psychotropic medications.

Wegovy is administered via weekly injection and, like insulin, is a subcutaneous medication that patients self-administer. Will patients be amenable to injecting a medication for weight loss? Dr. Stanford said that roughly 20%-30% of her patients are hesitant when she suggests that they use liraglutide, another GLP-1 receptor agonist that is approved for weight loss, and some are very fearful of needles.

However, she also noted that during the COVID-19 pandemic, many more patients have sought treatment from obesity medicine physicians because of the association between obesity and mortality from COVID-19. Patients have been willing to consider treatments that they were not previously open to pursuing.

So if people are willing to take Wegovy and doctors are willing to prescribe it, will insurers pay for it? As of this writing, the medication is not yet available, but Ozempic, the lower-dose agent for diabetes, costs $850-$900 for a 4-week supply, according to the GoodRx website.

Liraglutide (Saxenda), the GLP-1 receptor agonist that is currently available for weight loss as a daily injectable, costs $1,300-$1,400 per month.

These medications are not covered by Medicare or Medicaid, and Dr. Stanford, who is well versed as to exactly which private insurers in Massachusetts will and will not reimburse specific medications, said her patients with insurance coverage have been known to delay retirement so that they can remain on the more expensive medications.

“For the past 8 years,” she said, “the Treat and Reduce Obesity Act has had bipartisan support in Congress but has not passed. We are still hopeful that insurers will be required to cover medical and behavioral treatments for obesity.”

As our society struggles to destigmatize so many disorders, obesity remains a highly stigmatized condition, one that our patients cannot hide and one that leads to so many other comorbid illnesses. As new treatments are approved, there will be more for physicians to offer. Semaglutide, if it becomes available to those who need it most, could be a game changer. For patients who have not had success with traditional weight-loss methods, it’s encouraging to have another option available, one that may be reasonable to try before resorting to bariatric surgery.

For decades, psychiatrists have been comfortable prescribing treatments that lead to weight gain. Now, maybe it’s time they also prescribe those that prevent it.

Patients have been willing to consider treatments that they were not previously open to pursuing.

So if people are willing to take Wegovy and doctors are willing to prescribe it, will insurers pay for it? As of this writing, the medication is not yet available, but Ozempic, the lower-dose agent for diabetes, costs $850-$900 for a 4-week supply, according to the GoodRx website.

Liraglutide (Saxenda), the GLP-1 receptor agonist that is currently available for weight loss as a daily injectable, costs $1,300-$1,400 per month.

These medications are not covered by Medicare or Medicaid, and Dr. Stanford, who is well versed as to exactly which private insurers in Massachusetts will and will not reimburse specific medications, said her patients with insurance coverage have been known to delay retirement so that they can remain on the more expensive medications.

“For the past 8 years,” she said, “the Treat and Reduce Obesity Act has had bipartisan support in Congress but has not passed. We are still hopeful that insurers will be required to cover medical and behavioral treatments for obesity.”

As our society struggles to destigmatize so many disorders, obesity remains a highly stigmatized condition, one that our patients cannot hide and one that leads to so many other comorbid illnesses. As new treatments are approved, there will be more for physicians to offer. Semaglutide, if it becomes available to those who need it most, could be a game changer. For patients who have not had success with traditional weight-loss methods, it’s encouraging to have another option available, one that may be reasonable to try before resorting to bariatric surgery.

For decades, psychiatrists have been comfortable prescribing treatments that lead to weight gain. Now, maybe it’s time they also prescribe those that prevent it.

Remote cognitive tests often rival in-person tests with respect to reliability. That is the message behind numerous publications in recent years, and the COVID-19 pandemic has accelerated that trend.

“The publications have just skyrocketed since 2018, but I think there are still some additional tests that we need to validate using this medium of assessment. Also, I think we need to kind of put on our thinking caps as a field and think outside the box. What novel tests can we develop that will capitalize upon the telehealth environment – interactive tests that are monitoring [the individuals’] performance in real time and giving the examiner feedback, things like that,” said Munro Cullum, PhD, in an interview. Dr. Cullum spoke on the topic at the 2021 Alzheimer’s Association International Conference.

Still, challenges remain, especially factors in the home environment that can adversely affect testing. “Some of our tests are a question-answer, pencil-paper sort of tests that can be well suited to a telemedicine environment, [but] other tests don’t translate as well. So we still have a ways to go to kind of get our test to the next generation when being administered during this type of assessment. But a lot of the verbal tests work extremely well,” said Dr. Cullum, who is a professor of psychiatry at the University of Texas Southwestern Medical Center, Dallas.
 

Preliminary evidence of equivalence

Some years ago, Dr. Cullum was interested in getting a better understanding of what existing tests could best be performed remotely, and what populations could most benefit from remote assessments. Existing studies were generally supportive of remote testing, but varied significantly in their methodology and design. He went on to publish a study in 2014 showing equivalency of existing tests in the in-person and remote environment, and that helped pave the way for a wave of more recent studies that seem to confirm equivalence of in-person methods.

“If you look at the literature overall, there is a nice, growing body of evidence suggesting support for a host of neuropsychological test instruments. For the most part, almost all have shown good reliability across test conditions,” Dr. Cullum said during the talk.

He said that he is often asked if different test norms will be required for remote tests, but that doesn’t seem to be a concern. “It looks like the regular old neuropsych test norms should serve as well in this remote assessment environment. Although as within hospital testing of patients, conservative use of norms is always an order. They are interpretive guidelines,” he added.

One concern is potential threats to validity within the home environment. He posted an image of a woman at home, taking a remote cognitive test. The desk she sat at overlooked a wooded scene, and had a sewing machine on it. A small dog lay in her lap. “So assessing the home environment, ensuring that it is as close to a clinical standard setting as possible, is certainly advised,” said Dr. Cullum.

Although much progress has been made in studying existing tests in a telemedicine environment, many commonly used tests still haven’t been studied. The risk of intrusions and distractions, and even connectivity issues, can be limiting factors. Some tests may be ineligible for remote use due to copyright issues that might prevent required materials from being displayed online. For those reasons and others, not all individuals are suited for a remote test.

Finally, remote tests should be viewed with healthy skepticism. “In doing clinical evaluations this way, we have to be extra careful to not mis- or overinterpret the findings in case there were any distractions or glitches in the examination that came up during the test,” said Dr. Cullum.
 

Looking toward the future

Moving forward, Dr. Cullum called for more research to design new tests to exploit the telehealth format. “I think this is a really important opportunity for new test development in neuropsychology with increasing incorporation of computerized measures and integration with more cognitive neuroscience and clinical neuropsychology principles.”

He also suggested that remote testing could be combined with neuroimaging, neuromodulation, and even portable magnetoencephalography. “These opportunities for research can enhance compliance, enhance large-scale studies to allow for the inclusion of brief cognitive outcome metrics that might not have other otherwise been [possible],” said Dr. Cullum.

During the question-and-answer session, someone asked if the momentum towards telehealth will continue once the COVID-19 pandemic recedes. “We believe telehealth is here to stay, or at least I do,” said session moderator Allison Lindauer, PhD, who was asked to comment. Dr. Lindauer is an associate professor at the Layton Aging and Alzheimer’s Disease Center in Portland, Ore.

Dr. Lindauer has also conducted studies on telehealth-delivered assessments and also found encouraging results. “Work like this says, we have confidence in our work, we can believe that what we’re assessing and what we’re doing – if we did it face to face, we would get similar results,” Dr. Lindauer said in an interview.

Plenty of challenges remain, and the most important is widely available broadband internet, said Dr. Lindauer. “We need a huge push to get broadband everywhere. Granted, you’re going to have people that don’t want to use the computer, or they’re nervous about doing it online. But in my experience, most people with enough coaching can do it and are fine with it.”

Dr. Cullum and Dr. Lindauer have no relevant financial disclosures.

Reducing exposure to air pollution may slow brain aging and reduce the risk of dementia, new research reveals. The findings have implications for individual behaviors, such as avoiding areas with poor air quality, but they also have implications for public policy, said study investigator, Xinhui Wang, PhD, assistant professor of research neurology, department of neurology, University of Southern California, Los Angeles.

“Controlling air quality has great benefits not only for the short-term, for example for pulmonary function or very broadly mortality, but can impact brain function and slow memory function decline and in the long run may reduce dementia cases.”

The findings were presented at the 2021 Alzheimer’s Association International Conference.
 

New approach

Previous research examining the impact of reducing air pollution, which has primarily examined respiratory illnesses and mortality, showed it is beneficial. However, no previous studies have examined the impact of improved air quality on cognitive function.

The current study used a subset of participants from the Women’s Health Initiative Memory Study-Epidemiology of Cognitive Health Outcomes (WHIMS-ECHO), which evaluated whether postmenopausal women derive cognitive benefit from hormone therapy.

The analysis included 2,232 community-dwelling older women aged 74-92 (mean age, 81.5 years) who did not have dementia at study enrollment.

Researchers obtained measures of participants’ annual cognitive function from 2008 to 2018. These measures included general cognitive status assessed using the Telephone Interview for Cognitive Status-modified (TICSm) and episodic memory assessed by the telephone-based California Verbal Learning Test (CVLT).

The investigators used complex geographical covariates to estimate exposure to fine particulate matter (PM_2.5) and nitrogen dioxide (NO₂), in areas where individual participants lived from 1996 to 2012. The investigators averaged measures over 3-year periods immediately preceding (recent exposure) and 10 years prior to (remote exposure) enrollment, then calculated individual-level improvements in air quality as the reduction from remote to recent exposures.

The researchers examined pollution exposure and cognitive outcomes at different times to determine causation.

“Maybe the relationship isn’t causal and is just an association, so we tried to separate the timeframe for exposure and outcome and make sure the exposure was before we measured the outcome,” said Dr. Wang.

The investigators adjusted for multiple sociodemographic, lifestyle, and clinical characteristics.
 

Reduced dementia risk

The analysis showed air quality improved significantly for both PM_2.5 and NO₂ before study enrollment. “For almost 95% of the subjects in our study, air quality improved over the 10 years,” said Dr. Wang.

During a median follow-up of 6.2 years, there was a significant decline in cognitive status and episodic memory in study participants, which makes sense, said Dr. Wang, because cognitive function naturally declines with age.

However, a 10% improvement in air quality PM_2.5 and NO₂ resulted in a respective 14% and 26% decreased risk for dementia. This translates into a level of risk seen in women 2 to 3 years younger.

Greater air quality improvement was associated with slower decline in both general cognitive status and episodic memory.

“Participants all declined in cognitive function, but living in areas with the greatest air quality improvement slowed this decline,” said Dr. Wang.

“Whether you look at global cognitive function or memory-specific function, and whether you look at PM_2.5 or NO₂, slower decline was in the range of someone who is 1-2 years younger.”

The associations did not significantly differ by age, region, education, APOE ε4 genotypes, or cardiovascular risk factors.

Patients concerned about cognitive decline can take steps to avoid exposure to pollution by wearing a mask; avoiding heavy traffic, fires, and smoke; or moving to an area with better air quality, said Dr. Wang.

“But our study mainly tried to provide some evidence for policymakers and regulators,” she added.

Another study carried out by the same investigators suggests pollution may affect various cognitive functions differently. This analysis used the same cohort, timeframe, and air quality improvement indicators as the first study but examined the association with specific cognitive domains, including episodic memory, working memory, attention/executive function, and language.

The investigators found women living in locations with greater PM_2.5 improvement performed better on tests of episodic memory (P = .002), working memory (P = .01) and attention/executive function (P = .01), but not language. Findings were similar for improved NO₂.

When looking at air quality improvement and trajectory slopes of decline across cognitive functions, only the association between improved NO₂ and slower episodic memory decline was statistically significant (P < 0.001). “The other domains were marginal or not significant,” said Dr. Wang.

“This suggests that brain regions are impacted differently,” she said, adding that various brain areas oversee different cognitive functions.
 

Important policy implications

Commenting on the research, Rebecca Edelmayer, PhD, senior director of scientific engagement, Alzheimer’s Association, said she welcomes new research on environmental factors that affect Alzheimer’s disease.

Whereas previous studies have linked longterm air pollution exposure to accumulation of Alzheimer’s disease-related brain plaques and increased risk of dementia, “these newer studies provide some of the first evidence to suggest that actually reducing pollution is associated with lower risk of all-cause dementia,” said Dr. Edelmayer.

Individuals can control some factors that contribute to dementia risk, such as exercise, diet, and physical activity, but it’s more difficult for them to control exposure to smog and pollution, she said.

“This is probably going to require changes to policy from federal and local governments and businesses, to start addressing the need to improve air quality to help reduce risk for dementia.”
