California-based emergency physician Simone Melissa Gold, MD, JD, founder of the antivaccine group America’s Frontline Doctors (AFD) and leading voice in the antivaccine movement, has pleaded guilty to one of five charges related to the Jan. 6 Capitol riot.

According to the plea deal, Dr. Gold pleaded guilty to charges that she “did unlawfully and knowingly enter and remain in a restricted building and grounds, that is, any posted, cordoned-off, or otherwise restricted area within the United States Capitol and its grounds, during a time when the vice president was in the building without lawful authority to do so.” As part of the agreement, additional charges against her – obstructing an official proceeding and intent to disrupt the orderly conduct of government business – will be dismissed. She also agreed to cooperate with investigators, including allowing them to review social media postings made during the time surrounding the event.

Shortly after she was indicted, Dr. Gold told The Washington Post that she did not see any violence and that the event was “peaceful.” However, according to news reports, Dr. Gold acknowledged in her plea deal that she and her codefendant, John Herbert Strand, witnessed the assault of a police officer while they were outside the building.

Dr. Gold, 56, based in Beverly Hills, Calif., founded AFD in 2019. The group notes its goal is to “amplify the voices of concerned physicians and patients nationwide to combat those who push political and economic agendas at the expense of science and quality health care solutions.” Mr. Strand is the organization’s communication’s director.

The group has been a leading proponent of the use of ivermectin as a “safe and effective treatment” for COVID-19, according to its website.

In 2021, Dr. Gold spoke at an event called The Stand, representing AFD, where she promised to tell “the truth” about COVID vaccines, including that it was actually giving people the virus, that COVID was renamed from the “Wuhan Virus” as part of a cover-up, and touted treatments, including hydroxycholoroquine and ivermectin.

Dr. Gold has been one of the leading voices in the anti-vaccine movement. She has more than 400,000 Twitter followers; her Twitter profile includes a pinned tweet saying: “We are living in Orwellian times.” In addition to spreading vaccine misinformation, Dr. Gold has promoted the use of unproven treatments such as hydroxychloroquine and ivermectin.

Calls and emails to AFD regarding a statement on Gold’s plea made by this news organization were not returned by press time.

In October, Representative James E. Clyburn (D-S.C.), chairman of the Select Subcommittee on the Coronavirus Crisis, launched an investigation into organizations, including AFD, that spread misinformation and facilitate access to disproven and potentially hazardous treatments for COVID-19. According to news reports, Rep. Clyburn called the AFD and other such groups “predatory actors.”

Hospitals where Dr. Gold previously worked, including Providence St. Joseph Medical Center in Santa Monica, Calif., and Cedars-Sinai in Los Angeles, have disassociated themselves from her. On July 29, 2020, Cedars-Sinai Medical Center, where Gold previously worked, issued a statement that said, in part, “Simone Gold, MD, has not worked with Cedars-Sinai Medical Center or any of its offices or affiliates since 2015. For 3 weeks in late 2015, Dr. Gold was employed on a per diem basis by Cedars-Sinai Medical Network, a component of Cedars-Sinai. She worked during this brief time in a network urgent care clinic. Dr. Gold is not authorized to represent or speak about any information on behalf of Cedars-Sinai.”

Dr. Gold’s medical license in the state of California is current and she has no pending hearings before the state medical board, according to its website. On her own website, Dr. Gold says she “voluntarily refused” to renew her board certification last year, “due to the unethical behavior of the medical boards.”

Dr. Gold is also a licensed attorney, having earned her law degree in health policy analysis at Stanford (Calif.) Law School.

Dr. Gold faces 6 months in prison. Sentencing is scheduled for June 16.

“Adipose tissue is an underappreciated and misunderstood organ.” It’s with these words that Aaron M. Cypess, MD, PhD, begins his recent review published in the New England Journal of Medicine.

As obesity rates steadily rise, “the riskiest approach to human adipose tissue is to dismiss its importance,” he adds, especially because there has been “an explosive growth” in our understanding of white and brown adipose tissue over the past 5 to 10 years.

This news organization asked Dr. Cypess, a National Institutes of Health (NIH) scientist whose research focuses on brown fat, to discuss some of the main points in his review, titled, “Reassessing Human Adipose Tissue,” and clear up some misconceptions about fat.

You write that, for people who struggle to lose weight, “fat is often a source of misery, not marvel.” Why is fat a marvel?

When I started medical school in 1992, fat was just a thing that stored calories. You had to get it out of the way when you operated on the stomach or intestines. Now we know it’s not just one cell, it’s multiple types of cells, including immune cells and some blood cells. There’s cell turnover, and cells can get bigger or smaller, so it’s a dynamic tissue. It impacts the immune system and affects insulin sensitivity.

Why use the term “adipose tissue” and not just “fat”?

People think of fat cells and that’s it. However, adipose tissue (fat) has multiple cell types, and they each matter. There are adipocytes (fat cells) – which can be white, brown, beige, or pink – as well as immune cells, fibroblasts, blood vessels, and parts of nerve cells.

The main function of white adipose tissue is to store energy in the form of triglycerides. Brown adipose tissue consumes glucose and triglycerides, generating heat. Brown fat cells within depots of white fat are termed brite cells (a portmanteau of brown and white) or beige cells. Pink fat cells have been found in breast tissue in mice.

What do we now know about white fat and brown fat? Can brown fat change to white fat or vice versa?

White adipose tissue is commonly separated into visceral fat and subcutaneous fat, which have negative and neutral or positive metabolic effects, respectively. It is capable of more than doubling in mass and then returning to baseline.

White adipocyte-derived hormones include leptin, which is low in starvation, and adiponectin, which regulates glucose and lipid metabolism. White adipose tissue is essential for the proper function of the reproductive system, including secretion of hormones and lactation.

Brown adipose tissue protects newborns from cold as they develop the ability to shiver, and in adults it is found in depots in the neck, shoulders, posterior thorax, and abdomen. The amount of brown adipose tissue varies according to sex and lowers with increasing age and increasing body mass index.

There is much more white fat in the body than brown fat. It appears that activating brown fat leads to beneficial effects on metabolism, though we don’t know yet all the steps for how that happens.

In mice, you’ve got white fat depots and brown fat depots, and some brown fat can be found in the white fat.

With humans it’s much more complicated, and I’ve seen this in the operating room myself, and on slides. Where you find brown fat cells you also find a certain proportion of white fat cells, not an exclusive brown fat depot like you see in a mouse.

It is hotly debated right now whether brown fat can change to white fat and vice versa (transdifferentiation). The beige fat cells are supposed to be the kind that can shuttle between more white-like or brown-like. They can sometimes be white or sometimes brown. It can be very contentious in [scientific] papers and meetings.

Are humans born with all the fat cells they will ever have?

No. New fat cells are made throughout our lives. When the white adipocytes store too much triglyceride, they get really big and they get “sick” and die faster. It’s the rate at which the white cells take up the fat to store it and then get rid of it that can impact whether someone gains a lot of weight and whether they can successfully lose it after reasonable effort.

The average lifespan of a white fat cell is 15 years. We have no idea yet of the lifespan of a brown fat cell.

Is there a single “fat gene”? What role do fat genes play in the likelihood of developing metabolic diseases and type 2 diabetes?

Genes are very important for influencing the development of obesity and probably influence 50%-70% of obesity, based on studies in populations of predominantly European origin. But that high percentage reflects the impact of hundreds of genes. For most people, there is no one gene that exerts all of the effects. There are extremely rare diseases where one gene is responsible. Currently, only 20% of the entire phenotypic variation in obesity can be explained by the thousands of loci identified so far.

Why is it “correct but too simplistic” to attribute the increasing rates of obesity to excessive triglyceride storage in white adipose tissue?

Saying obesity is caused by too much triglyceride storage ignores the reasons how and why the triglycerides got there. There are likely to be multiple contributing factors to drive obesity, and those have billions of dollars of policy implications. Is obesity resulting from portion sizes? Then we should work on educating the public on how to estimate their caloric intake. Is it the types of foods, such as ultra-processed foods? Then we can discourage eating certain food groups while promoting others. Is it about physical activity? Then we should prioritize exercise programs.

Why is obesity “not simply a failure of will power”?

Genetic factors in adipose tissue impact how easy it is to store triglycerides, how easy it is to get fat out of the tissue and burn it up, and what kinds of hormones are released by the tissue to regulate appetite, insulin resistance, and inflammation. Ten different people can all overeat the same amount of the same foods, yet there will be differences in the amount of weight gain and metabolic complications experienced. And at the brain level, some people will feel “full” sooner than others.

How can excess adipose tissue lead to disease? Do some people have “metabolically healthy obesity”?

Excess adipose tissue leads to chronic inflammation that can then cause insulin resistance, hypertension, fatty liver disease, and other complications. It appears that there are metabolically healthy obese people, but it is not clear if that is only a temporary state.

Could long-term brown adipose tissue activation help treat obesity or related metabolic disease?

Our research group at the NIH and others have shown that long-term brown adipose tissue activation produces metabolic benefit such as improved insulin resistance, lower plasma glucose, and higher HDL [good] cholesterol. However, there is no evidence yet that it will lead to actual weight loss.

We are trying to use brown adipose tissue activation to treat obesity-related metabolic disease to see if it could lead to reduction in inflammation, improvement in the cholesterol profile, and decrease in blood pressure.

A large observational study published Jan. 4, 2021, in Nature Medicine by Paul Cohen’s group at Rockefeller University, in tens of thousands of people at Memorial Sloan Kettering Cancer Center, showed that people who had brown fat were generally healthier and had less high blood pressure and less cardiovascular disease. This study could not show causation, but at every BMI, people were healthier if they had more brown fat than if they had less. So, there’s something going on. We’re still trying to figure that out.

Dr. Cypess has no reported no relevant financial relationships.

Who is most at risk of suicide by drug overdose? Has that changed in recent years? Researchers at the National Institute on Drug Abuse analyzed data from 2001 to 2019 from the Centers for Disease Control and Prevention’s National Vital Statistics System to find out.

On the whole, they say, intentional overdose deaths have declined. But suicide rates increased in certain subgroups: young adults (aged 15-24 years), older adults (aged 75-84 years), and non-Hispanic Black women. Rates among women were “consistently higher” than those of men. The highest rates were observed in women aged 45 to 64 years.

Monday was the worst day, and the weekends had the lowest rates. The researchers say social factors, such as more social interactions on the weekend and reluctance about starting the workweek, could be factors.

Seasonally, the numbers ran true to the pattern seen in previous studies: The lowest rates occurred in December and highest in late spring and summer. Perhaps the “collective optimism” of the holiday season and social interactions exert protective effects against suicidality, the researchers suggest.

Factors also may include biological changes. In this study, the researchers found a positive linear relationship between daylength, which varies by latitude, and intentional overdose deaths for both sexes. Daylength is associated with mu opioid receptor (MOR) availability that might underlie seasonal variations in mood, they posit. MORs are the main target of opioid drugs; the researchers cite a study that found altered MOR expression in postmortem brains of suicide victims.

They note some limitations of their study, one being that, in 2019, 5% of overdose deaths had undetermined intent. Improving classifications of overdose deaths is needed, they say.

Moreover, the trends might have changed during the pandemic, as provisional mortality data indicate decreases in deaths by suicides, but also an approximate 30% increase in overall overdose deaths.

“This research underscores the importance of external support structures and environmental factors in determining a person’s suicide risk,” said Emily B. Einstein, PhD, chief of the National Institute on Drug Abuse’s Science Policy Branch and an author on the study. “The risk of intentional overdoses, and suicide risk in general, is not static. This is crucial for clinicians to keep in mind, as they may need to assess patients’ suicide risk frequently rather than at one point in time. It is also important for friends and family members of people who may be at an increased risk of suicide, and for those people themselves, so that they can be aware of the greatest periods of risk and seek help when needed.”

Unless air pollution and smoking patterns are reversed, lung cancer cases and deaths will grow unabated in some countries, according to estimates of lung cancer incident cases, deaths, and their age-standardized rates.

The findings, based on recently released data from GLOBOCAN 2020 projected to the year 2050, suggest that the lung cancer epidemic will continue to unfold, according to Rajesh Sharma, PhD, et al., in a study published in the International Journal of Clinical Oncology. GLOBOCAN 2020 is an online database produced by the International Agency for Research on Cancer. It provides global cancer statistics from 185 countries for 36 cancer types.

The increase in lung cancer, the leading cancer worldwide in terms of deaths, is generally attributed to increases in cigarette smoking, Sharma et al. wrote. They point out that, while cigarette smoking is expected to have peaked in industrialized countries in the latter half of the twentieth century, the tobacco smoking epidemic is unfolding in regions of Asia and Africa with concomitant increases in lung cancer burden in several countries. Smoking is the most significant lung cancer risk factor, followed by air pollution (especially particulate matter, passive smoking, and occupational exposure to radon and asbestos).

The authors investigated bivariate associations between smoking prevalence and age-standardized rates of lung cancer, and projected lung cancer incident cases and deaths to 2050. They also looked at mortality-to-incidence, considered to be a proxy indicator of 5-year survival, and at human development index, a measure including life expectancy at birth, years of schooling, and standard of living. The results, they state, are expected to aid in policy formulation to combat the lung cancer burden at global, regional, and national levels.

Tobacco smoking prevalence was 21.9% worldwide in 2016, with tobacco smoking prevalence exceeding 25% in 57/149 countries. It was high in European countries with 5 of the top-10 countries among the 149 countries within Europe. Prevalence was greater than 10% in all European countries. Notably, 11/33 countries in Africa had a smoking prevalence less than 10%.

Analysis showed 2.21 million new lung cancer cases and 1.8 million deaths attributed to lung cancer worldwide in 2020, with males accounting for about two-thirds of the burden. The analysis projection for 2050 was for 3.8 million incident cases of lung cancer and 3.2 million lung cancer deaths globally. In 2050, lung cancer cases and deaths are projected to be more than 100,000 in 10/21 regions, led by Eastern Asia, projected to record 1.7 million incident cases and 1.5 million deaths.

The burden of lung cancer in regions of Asia and Africa is expected to increase at least twofold from 2020 to 2050, surpassing European regions that are expected to have the smallest increases. Also, while incident cases will remain much higher in Northern America than in Southeastern Asia and South-Central Asia, the number of lives lost is projected to be similar. The age-specific incidence and death rates rose with age such that the oldest age groups had the highest age-specific rates. With the human development index, mortality-to-incidence showed a negative correlation.

The authors wrote that worsening smoking and pollution levels in developing countries may push the future lung cancer burden much higher than these projections. Unless reversed, cases and death will grow unabated.

“Countering the burden of lung cancer also requires curtailment of other risk factors such as air pollution and exposure to carcinogens,” the authors wrote.

This research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors. The authors stated that they have no conflicts of interest.

Tremors and memory symptoms were identified among individuals in a primary care setting as early as 10 years before a Parkinson’s disease diagnosis in a new study.

Most research on the causes and early signs of Parkinson’s disease (PD) have involved patients of Northern European ancestry, Cristina Simonet, MD, of Queen Mary University of London, and colleagues wrote in their paper, published in JAMA Neurology.

Additionally, data on how PD might manifest in different ethnic groups are limited, they said.

In their nested case-control, the researchers examined data from electronic health records of an ethnically diverse population of 1,016,277 adults seen in primary care practices between 1990 and Feb. 6, 2018. They compared individuals with PD with those without PD or other neurologic conditions.

The researchers identified 10 age and sex-matched controls for each PD case, and also conducted an unmatched analysis after adjusting for age and sex. The final study population included 1,055 patients with PD and 1,009,523 controls. The population of PD cases was 15.7% Black, 19.7% South Asian, 50.9% White, and 8.3% other; the population of controls was 13.3% Black, 21.5% South Asian, 43.7% White, and 11.3% other.

“We observed a constellation of symptoms noted by general practitioners up to a decade before diagnosis of PD,” the researchers said. Symptoms were identified across three time intervals (less than 2 years, 2-5 years, and 5-10 years before diagnosis) to better evaluate exposure outcome associations.

In the matched analysis of midlife risk factors, epilepsy showed the strongest association with PD diagnosis across all time periods, and type 2 diabetes or hypertension 5-10 years before diagnosis was associated with later PD.

Prediagnostic signs of PD included both motor and nonmotor manifestations.

The matched analysis revealed a significant increased association between tremor and memory symptoms less than 2 years before diagnosis (adjusted odds ratios of 151.24 and 8.73, respectively) as well as up to 10 years before diagnosis for tremors and up to 5 years for memory symptoms (aOR, 11.4 and 3.09, respectively) in PD patients, compared with controls.

Other strong associations between PD and early nonmotor features in cases, compared with controls, included hypotension (aOR, 6.81), constipation (aOR, 3.29), and depression (aOR, 4.61).

In addition, the researchers found associations for epilepsy that had not been identified in previous studies, and these associations persisted in a replication analysis.

The study findings were limited by several factors, mainly the use of routine primary care data with underascertained factors of interest, and potential mislabeling of PD, the researchers noted. Other limitations included the lack of data on prescription medication for PD, and the recording of memory problems in primary care without supportive testing to confirm cognitive impairment.

The results support a range of comorbidities and symptoms that may present in primary care, and clinicians should consider PD as a possible cause, the researchers wrote.
 

Make early referral a priority

The study is important because of the lack of diversity in Parkinson’s disease research, lead author Dr. Simonet said in an interview.

“Over the last decade, the global population suffering from Parkinson’s disease has more than doubled,” she said. Causes may include the increasing numbers of older people with longer life expectancy. “However, it seems there are other factors, including environmental, genetic, and lifestyle, that might play a role in increasing the prevalence of Parkinson’s disease.”

“More representative studies, including minority ethnic groups and those living in areas of high social and economic deprivation, are needed,” Dr. Simonet emphasized.

She said that there is little research on the association with epilepsy and hearing loss in early PD, and “for that reason, our results should encourage further studies to confirm a possible link between these manifestations and Parkinson’s disease.”
 

Early detection may drive better diagnoses

The current study is important for understanding the prediagnostic features and risk factors that may allow for earlier detection of Parkinson’s disease, William Hung, MD, a geriatrics and palliative care specialist of the Icahn School of Medicine at Mount Sinai, New York, said in an interview. “Prior to this study, there was limited understanding of these features.

“One surprise [in the findings] was that ethnicity and socioeconomic deprivation do not appear to be associated with the risk of PD, in contrast to other illnesses such as dementia,” said Dr. Hung. “The array of prediagnostic features associated with PD is not surprising, but nonetheless important for clinicians to know to consider whether PD could be the underlying cause.”

The take-home message for primary care is that “there are features, such as hearing loss, history of epilepsy, autonomic symptoms, motor symptoms, among others, for which clinicians should consider PD as part of the differential diagnosis as underlying cause and consider referral to specialists for diagnostic clarification,” said Dr. Hung.

“Additional research is needed to translate these findings to care, perhaps developing decision aids, interventions that may help with diagnosis and evaluation,” as is work on understanding the link between PD and symptoms such as hearing loss and epilepsy, he said.
 

Primary care offers opportunity to identify risk factors

The current study represents an important step in early recognition of PD, with implications for helping patients access treatments promptly and improve their quality of life, Bhavana Patel, DO, Shannon Chiu, MD, and Melissa J. Armstrong, MD, of the University of Florida, Gainesville, wrote in an accompanying editorial.

“The primary care setting is commonly where symptoms heralding the onset of PD are first discussed. However, little is known regarding the prediagnostic manifestations of PD that are seen in primary care clinics, particularly in underserved populations,” they wrote.

The study included many risk factors and prodromal markers associated with research criteria for prodromal PD, but did not include several risk and prodromal markers in the Movement Disorders Society research criteria, “such as symptoms suggestive of REM sleep behavior disorder, excessive daytime sleepiness (which overlaps with, but is distinct from, fatigue), urinary dysfunction, pesticide and solvent exposure, caffeine use, level of physical activity, and family history,” they said.

Even in individuals with diagnosed PD, certain symptoms, particularly nonmotor symptoms, are commonly underreported,” and primary care clinicians may not recognize these symptoms as PD risk factors, the authors noted.

However, “in addition to contributing to possible models of modifiable risk factors for PD, study results may also further inform algorithms designed to predict PD diagnoses in primary care,” they said. The study also highlights the need for more multivariable models to better identify PD risk factors and strategies for early identification of PD in primary care.

Several study coauthors received funding related to the study from Barts Charity, Health Data Research UK, the Department of Health and Social Care (England) and the devolved administrations, and leading medical research charities, as well as the National Institute for Health Research UCLH Biomedical Research Centre. Lead author Dr. Simonet and Dr. Hung had no financial conflicts to disclose.

Additionally, data on how PD might manifest in different ethnic groups are limited, they said.

In their nested case-control, the researchers examined data from electronic health records of an ethnically diverse population of 1,016,277 adults seen in primary care practices between 1990 and Feb. 6, 2018. They compared individuals with PD with those without PD or other neurologic conditions.

The researchers identified 10 age and sex-matched controls for each PD case, and also conducted an unmatched analysis after adjusting for age and sex. The final study population included 1,055 patients with PD and 1,009,523 controls. The population of PD cases was 15.7% Black, 19.7% South Asian, 50.9% White, and 8.3% other; the population of controls was 13.3% Black, 21.5% South Asian, 43.7% White, and 11.3% other.

“We observed a constellation of symptoms noted by general practitioners up to a decade before diagnosis of PD,” the researchers said. Symptoms were identified across three time intervals (less than 2 years, 2-5 years, and 5-10 years before diagnosis) to better evaluate exposure outcome associations.

In the matched analysis of midlife risk factors, epilepsy showed the strongest association with PD diagnosis across all time periods, and type 2 diabetes or hypertension 5-10 years before diagnosis was associated with later PD.

Prediagnostic signs of PD included both motor and nonmotor manifestations.

The matched analysis revealed a significant increased association between tremor and memory symptoms less than 2 years before diagnosis (adjusted odds ratios of 151.24 and 8.73, respectively) as well as up to 10 years before diagnosis for tremors and up to 5 years for memory symptoms (aOR, 11.4 and 3.09, respectively) in PD patients, compared with controls.

Other strong associations between PD and early nonmotor features in cases, compared with controls, included hypotension (aOR, 6.81), constipation (aOR, 3.29), and depression (aOR, 4.61).

In addition, the researchers found associations for epilepsy that had not been identified in previous studies, and these associations persisted in a replication analysis.

The study findings were limited by several factors, mainly the use of routine primary care data with underascertained factors of interest, and potential mislabeling of PD, the researchers noted. Other limitations included the lack of data on prescription medication for PD, and the recording of memory problems in primary care without supportive testing to confirm cognitive impairment.

The results support a range of comorbidities and symptoms that may present in primary care, and clinicians should consider PD as a possible cause, the researchers wrote.
 

Make early referral a priority

The study is important because of the lack of diversity in Parkinson’s disease research, lead author Dr. Simonet said in an interview.

“Over the last decade, the global population suffering from Parkinson’s disease has more than doubled,” she said. Causes may include the increasing numbers of older people with longer life expectancy. “However, it seems there are other factors, including environmental, genetic, and lifestyle, that might play a role in increasing the prevalence of Parkinson’s disease.”

“More representative studies, including minority ethnic groups and those living in areas of high social and economic deprivation, are needed,” Dr. Simonet emphasized.

She said that there is little research on the association with epilepsy and hearing loss in early PD, and “for that reason, our results should encourage further studies to confirm a possible link between these manifestations and Parkinson’s disease.”
 

Early detection may drive better diagnoses

The current study is important for understanding the prediagnostic features and risk factors that may allow for earlier detection of Parkinson’s disease, William Hung, MD, a geriatrics and palliative care specialist of the Icahn School of Medicine at Mount Sinai, New York, said in an interview. “Prior to this study, there was limited understanding of these features.

“One surprise [in the findings] was that ethnicity and socioeconomic deprivation do not appear to be associated with the risk of PD, in contrast to other illnesses such as dementia,” said Dr. Hung. “The array of prediagnostic features associated with PD is not surprising, but nonetheless important for clinicians to know to consider whether PD could be the underlying cause.”

The take-home message for primary care is that “there are features, such as hearing loss, history of epilepsy, autonomic symptoms, motor symptoms, among others, for which clinicians should consider PD as part of the differential diagnosis as underlying cause and consider referral to specialists for diagnostic clarification,” said Dr. Hung.

“Additional research is needed to translate these findings to care, perhaps developing decision aids, interventions that may help with diagnosis and evaluation,” as is work on understanding the link between PD and symptoms such as hearing loss and epilepsy, he said.
 

Primary care offers opportunity to identify risk factors

The current study represents an important step in early recognition of PD, with implications for helping patients access treatments promptly and improve their quality of life, Bhavana Patel, DO, Shannon Chiu, MD, and Melissa J. Armstrong, MD, of the University of Florida, Gainesville, wrote in an accompanying editorial.

“The primary care setting is commonly where symptoms heralding the onset of PD are first discussed. However, little is known regarding the prediagnostic manifestations of PD that are seen in primary care clinics, particularly in underserved populations,” they wrote.

The study included many risk factors and prodromal markers associated with research criteria for prodromal PD, but did not include several risk and prodromal markers in the Movement Disorders Society research criteria, “such as symptoms suggestive of REM sleep behavior disorder, excessive daytime sleepiness (which overlaps with, but is distinct from, fatigue), urinary dysfunction, pesticide and solvent exposure, caffeine use, level of physical activity, and family history,” they said.

Even in individuals with diagnosed PD, certain symptoms, particularly nonmotor symptoms, are commonly underreported,” and primary care clinicians may not recognize these symptoms as PD risk factors, the authors noted.

However, “in addition to contributing to possible models of modifiable risk factors for PD, study results may also further inform algorithms designed to predict PD diagnoses in primary care,” they said. The study also highlights the need for more multivariable models to better identify PD risk factors and strategies for early identification of PD in primary care.

Several study coauthors received funding related to the study from Barts Charity, Health Data Research UK, the Department of Health and Social Care (England) and the devolved administrations, and leading medical research charities, as well as the National Institute for Health Research UCLH Biomedical Research Centre.

Pregnant women with a history of spontaneous abortion had a significantly increased risk of gestational diabetes in subsequent pregnancies, based on data from more than 100,000 women.

Gestational diabetes is associated not only with adverse perinatal outcomes, but also with an increased risk of long-term cardiovascular and metabolic health issues in mothers and children, wrote Yan Zhao, PhD, of Tongji University, Shanghai, and colleagues.

Previous studies also have shown that spontaneous abortion (SAB) is associated with later maternal risk of cardiovascular disease and venous thromboembolism, the researchers said. The same mechanisms might contribute to the development of gestational diabetes, but the association between abortion history and gestational diabetes risk in subsequent pregnancies remains unclear, they added.

In a study published in JAMA Network Open, the researchers identified 102,259 pregnant women seen for routine prenatal care at a single hospital in Shanghai between January 2014 and December 2019. The mean age of the women was 29.8 years.

During the study period, 14,579 women experienced SAB (14.3%), 17,935 experienced induced abortion (17.5%), and 4,017 experienced both (11.9%).

In all, 12,153 cases of gestational diabetes were identified, for a prevalence of 11.9%. The relative risk of gestational diabetes was 1.25 for women who experienced SAB and 1.15 for those who experienced both SAB and induced abortion, and the association between SAB and gestational diabetes increased in a number-dependent manner, the researchers said. The increase in relative risk for gestational diabetes in pregnant women with one SAB, two SABs, and three or more SABs was 18%, 41%, and 43%, compared to pregnant women with no SAB history.

However, no association appeared between a history of induced abortion and gestational diabetes, the researchers said. “To date, no study has reported the association of prior induced abortion with gestational diabetes,” they wrote.

The study findings were limited by several factors including the reliance on self-reports for history of SAB and therefore possible underreporting, the researchers noted. Other limitations included the lack of data on the timing of SABs; therefore, the time between SAB and gestational diabetes diagnosis could not be included in the analysis, they said. Unknown variables and the inclusion only of women from a single city in China might limit the generalizability of the results, they added.

More research is needed to understand the biological mechanisms behind the association between SAB and gestational diabetes, an association that has potential public health implications, they noted. However, the results suggest that “pregnant women with a history of SAB, especially those with a history of recurrent SAB, should attend more antenatal visits to monitor their blood glucose and implement early prevention and intervention,” such as healthful eating and regular exercise, they wrote.
 

Findings confirm, not surprise

The diagnosis of gestational diabetes in the current study “was made with a slightly different test than we typically use in the United States – a 1-hour nonfasting glucola followed by a confirmatory 3-hour fasting glucola,” Sarah W. Prager, MD, of the University of Washington, Seattle, said in an interview. The current study of both SAB and gestational diabetes is important because both conditions are very common and have been the focus of increased attention in the popular media and in scientific study, she said.

Dr. Prager said she was not surprised by the findings of a link between a history of gestational diabetes and a history of SAB, “but the association is likely that people at risk for gestational diabetes or who have undiagnosed diabetes/glucose intolerance are more likely to experience SAB,” she noted. “I would be surprised if the direction of the association is that SAB puts people at risk for gestational diabetes; more likely undiagnosed diabetes is a risk factor for SAB,” she added. “Perhaps we should be screening for glucose intolerance and other metabolic disorders more frequently in people who have especially recurrent SAB, as the more miscarriages someone had, the more likely they were in this study to be diagnosed with gestational diabetes;” or perhaps those with a history of SAB/recurrent SAB should be screened closer to 24 weeks’ than 28 weeks’ gestation to enable earlier intervention in those more likely to have gestational diabetes, Dr. Prager said.

The study was supported by the Key Program of the National Natural Science Foundation of China, the National Natural Science Foundation of China, the National Key Research and Development Program of China, the Shanghai Municipal Medical and Health Discipline Construction Projects, and the Shanghai Rising-Star Program. The researchers and Dr. Prager had no financial conflicts to disclose. Dr. Prager serves on the editorial advisory board of Ob.Gyn. News.

From environmental tobacco smoke to ultraviolet (UV) radiation, diesel exhaust particulates, lead, and now, chronic infection with Helicobacter pylori (H pylori)—the Report on Carcinogens has regularly updated the list of substances known or “reasonably anticipated” to cause cancer.

The 15th report, which is prepared by the National Toxicology Program (NTP) for the Department of Health and Human Services, has 8 new entries, bringing the number of human carcinogens (eg, metals, pesticides, and drugs) on the list to 256. (The first report, released in 1980, listed 26.) In addition to H pylori infection, this edition adds the flame-retardant chemical antimony trioxide, and 6 haloacetic acids found as water disinfection byproducts.

In 1971, then President Nixon declared “war on cancer” (the second leading cause of death in the US) and signed the National Cancer Act. In 1978, Congress ordered the Report on Carcinogens, to educate the public and health professionals on potential environmental carcinogenic hazards.

Perhaps disheartening to know that even with 256 entries, the list probably understates the number of carcinogens humans and other creatures are exposed to. But things can change with time. Each list goes through a rigorous round of reviews. Sometimes substances are “delisted” after, for instance, litigation or new research. Saccharin, for example, was removed from the ninth edition. It was listed as “reasonably anticipated” in 1981, based on “sufficient evidence of carcinogenicity in experimental animals.” It was removed, however, after extensive review of decades of saccharin use determined that the data were not sufficient to meet current criteria. Further research had revealed, also, that the observed bladder tumors in rats arose from a mechanism not relevant to humans.

Other entries, such as the controversial listing of the cancer drug tamoxifen, walk a fine line between risk and benefit. Tamoxifen, first listed in the ninth report (and still in the 15th report), was included because studies revealed that it could increase the risk of uterine cancer in women. But there also was conclusive evidence that it may prevent or delay breast cancer in women who are at high risk.

Ultimately, the report’s authors make it clear that it is for informative value and guidance, not necessarily a dictate. As one report put it: “Personal decisions concerning voluntary exposures to carcinogenic agents need to be based on additional information that is beyond the scope” of the report.

“As the identification of carcinogens is a key step in cancer prevention,” said Rick Woychik, PhD, director of the National Institute of Environmental Health Sciences and NTP, “publication of the report represents an important government activity towards improving public health.”

Multiple psychiatric groups have asked the U.S. Food and Drug Administration to consider holding a public meeting about its approach to risk management of the schizophrenia drug clozapine, which is effective but carries serious risks, including death.

In a Feb. 14 letter, the groups asked the FDA to reconsider its new risk evaluation and mitigation strategy (REMS) for clozapine because of concerns it had the potential to cause abrupt discontinuation of the medication.

The groups cite an Institute for Safe Medication Practices (ISMP) report of a 40-year-old woman who was a long-time clozapine user, had a cardiac arrest, and died after she stopped taking the drug because her psychiatrist was unable to register for the updated version of the REMS.

“It is unacceptable for a REMS with unproven effectiveness at meeting its goal to carry risks of interruptions that can result in rehospitalization, acute exacerbation of psychosis, increased risk of suicide, and potentially fatal orthostatic hypotension/bradycardic syndromes associated with incorrect restarts,” the groups said in the letter.

“We feel certain that this case reported in the literature is not the only serious adverse outcome from the REMS and the transition,” they added.

The letter was signed by the American Psychiatric Association, the American Association for Community Psychiatry, the American Psychiatric Nurses Association, the College of Psychiatric and Neurologic Pharmacists, the National Alliance on Mental Illness, the National Association of State Mental Health Program Directors, and the National Council for Mental Wellbeing.

Clozapine can decrease the neutrophil count, which can lead to severe neutropenia, serious infection, and death. Consequently, the FDA put additional safety measures in place governing clozapine prescribing.

In 2015, a centralized clozapine REMS replaced separate prescribing registries that the drug manufacturers maintained. There were technical issues with the 2015 start-up of that website, including data migration problems and long call wait times, the FDA said.

Subsequently, the drug’s manufacturers then decided to change the REMS platform, which created new issues that led to high call volume and long wait times for clinicians and pharmacists who were trying to enroll.
 

Maintaining access

In November 2021, the FDA announced it would put some aspects of a planned switch on hold. A month later, the agency made further modifications to its plan.

The FDA said it would exercise “enforcement discretion” to try to maintain access to clozapine amid hitches with the REMS transition efforts. The agency also said at the time that it would not object if pharmacists dispensed clozapine without the usual authorization. In addition, wholesalers could ship the drug to pharmacies and health care settings without confirming REMS enrollment.

The FDA also held two December meetings to allow various stakeholders to air concerns.

In their letter, the APA and other groups asked if the FDA intends to continue with accommodations, such as allowing pharmacies to order clozapine from wholesalers without restriction.

“We do not feel the issues are resolved,” the groups said.

“It is unacceptable for a REMS with unproven effectiveness at meeting its goal to carry risks of interruptions that can result in rehospitalization, acute exacerbation of psychosis, increased risk of suicide, and potentially fatal orthostatic hypotension/bradycardic syndromes associated with incorrect restarts,” the groups said in the letter.

“We feel certain that this case reported in the literature is not the only serious adverse outcome from the REMS and the transition,” they added.

The letter was signed by the American Psychiatric Association, the American Association for Community Psychiatry, the American Psychiatric Nurses Association, the College of Psychiatric and Neurologic Pharmacists, the National Alliance on Mental Illness, the National Association of State Mental Health Program Directors, and the National Council for Mental Wellbeing.

Clozapine can decrease the neutrophil count, which can lead to severe neutropenia, serious infection, and death. Consequently, the FDA put additional safety measures in place governing clozapine prescribing.

In 2015, a centralized clozapine REMS replaced separate prescribing registries that the drug manufacturers maintained. There were technical issues with the 2015 start-up of that website, including data migration problems and long call wait times, the FDA said.

Subsequently, the drug’s manufacturers then decided to change the REMS platform, which created new issues that led to high call volume and long wait times for clinicians and pharmacists who were trying to enroll.
 

Maintaining access

In November 2021, the FDA announced it would put some aspects of a planned switch on hold. A month later, the agency made further modifications to its plan.

The FDA said it would exercise “enforcement discretion” to try to maintain access to clozapine amid hitches with the REMS transition efforts. The agency also said at the time that it would not object if pharmacists dispensed clozapine without the usual authorization. In addition, wholesalers could ship the drug to pharmacies and health care settings without confirming REMS enrollment.

The FDA also held two December meetings to allow various stakeholders to air concerns.

In their letter, the APA and other groups asked if the FDA intends to continue with accommodations, such as allowing pharmacies to order clozapine from wholesalers without restriction.

“We do not feel the issues are resolved,” the groups said.

Earlier menopause appears to be associated with a higher risk of dementia, and earlier onset of dementia, compared with menopause at normal age or later, according to a large study.

“Being aware of this increased risk can help women practice strategies to prevent dementia and to work with their physicians to closely monitor their cognitive status as they age,” study investigator Wenting Hao, MD, with Shandong University, Jinan, China, says in a news release.

The findings were presented in an e-poster March 1 at the Epidemiology, Prevention, Lifestyle & Cardiometabolic Health (EPI|Lifestyle) 2022 conference sponsored by the American Heart Association.
 

UK Biobank data

Dr. Hao and colleagues examined health data for 153,291 women who were 60 years old on average when they became participants in the UK Biobank.

Age at menopause was categorized as premature (younger than age 40), early (40 to 44 years), reference (45 to 51), 52 to 55 years, and 55+ years.

Compared with women who entered menopause around age 50 years (reference), women who experienced premature menopause were 35% more likely to develop some type of dementia later in life (hazard ratio, 1.35; 95% confidence interval, 1.22 to 1.91).

Women with early menopause were also more likely to develop early-onset dementia, that is, before age 65 (HR, 1.31; 95% confidence interval, 1.07 to 1.72).

Women who entered menopause later (at age 52+) had dementia risk similar to women who entered menopause at the average age of 50 to 51 years.

The results were adjusted for relevant cofactors, including age at last exam, race, educational level, cigarette and alcohol use, body mass index, cardiovascular disease, diabetes, income, and leisure and physical activities.

Blame it on estrogen?

Reduced estrogen levels may be a factor in the possible connection between early menopause and dementia, Dr. Hao and her colleagues say.

Estradiol plays a key role in a range of neurological functions, so the reduction of endogenous estrogen at menopause may aggravate brain changes related to neurodegenerative disease and speed up progression of dementia, they explain.

“We know that the lack of estrogen over the long term enhances oxidative stress, which may increase brain aging and lead to cognitive impairment,” Dr. Hao adds.

Limitations of the study include reliance on self-reported information about age at menopause onset.

Also, the researchers did not evaluate dementia rates in women who had a naturally occurring early menopause separate from the women with surgery-induced menopause, which may affect the results.

Finally, the data used for this study included mostly White women living in the U.K. and may not generalize to other populations.
 

Supportive evidence, critical area of research

The U.K. study supports results of a previously reported Kaiser Permanente study, which showed women who entered menopause at age 45 or younger were at 28% greater dementia risk, compared with women who experienced menopause after age 45.

Reached for comment, Heather Snyder, PhD, Alzheimer’s Association vice president of medical and scientific relations, noted that nearly two-thirds of Americans with Alzheimer’s are women.

“We know Alzheimer’s and other dementias impact a greater number of women than men, but we don’t know why,” she told this news organization.

“Lifelong differences in women may affect their risk or affect what is contributing to their underlying biology of the disease, and we need more research to better understand what may be these contributing factors,” said Dr. Snyder.

“Reproductive history is one critical area being studied. The physical and hormonal changes that occur during menopause – as well as other hormonal changes throughout life – are considerable, and it’s important to understand what impact, if any, these changes may have on the brain,” Dr. Snyder added.

“The potential link between reproduction history and brain health is intriguing, but much more research in this area is needed to understand these links,” she said.

The study was funded by the Start-up Foundation for Scientific Research at Shandong University. Dr. Hao and Dr. Snyder have disclosed no relevant financial relationships.

Research suggests that physicians have suicidal thoughts at about twice the rate of the general population (7.2% vs. 4%). Now, as they bear the weight of a multiyear pandemic alongside the perpetual struggle to maintain some semblance of work-life balance, their resiliency has been stretched to the brink.

In 2022, the Medscape Physician Suicide Report surveyed more than 13,000 physicians in 29 specialties who were candid about their experiences with suicidal thoughts, how they support their besieged colleagues, and their go-to coping strategies.

Overall, 21% of physicians reported having feelings of depression. Of those, 24% had clinical depression and 64% had colloquial depression. Physicians who felt sad or blue decreased slightly, compared with the 2021 report, but the number of physicians experiencing severe depression rose 4%.

One in 10 physicians said they have thought about or attempted suicide. However, the number of physicians with suicidal thoughts dropped to 9%, down substantially from the 22% who reported similar feelings in 2020.

Still, there was a slight uptick in women physicians contemplating suicide, likely linked to their larger share of childcare and family responsibilities.

Washington University School of Medicine

“They have needed to pull double duty even more than usual, and that may have increased their sense of burnout and vulnerability to suicidal thoughts,” said Andrea Giedinghagen, MD, assistant professor in the department of psychiatry at Washington University in St. Louis, and coauthor of “Physician Suicide: A Call to Action
 

Fighting the stigma of seeking mental health help

Although the number of physicians attempting, but not completing suicide, has remained steady at 1% for several years, the recent passage of the Dr. Lorna Breen Health Care Provider Protection Act by Congress aims to drive that figure even lower. Dr. Breen, an ED physician at New York–Presbyterian Hospital, died by suicide in April 2020. Overwhelmed by the onslaught of COVID patients, Dr. Breen was reluctant to seek mental health services for fear of being ostracized.

“Many physicians don’t seek mental health care due to fear of negative consequences in the workplace, including retribution, exclusion, loss of license, or even their job,” Gary Price, MD, president of The Physicians Foundation, told this news organization. “This was the experience of Dr. Lorna Breen. She was convinced that if she talked to a professional, she would lose her medical license. Perhaps if Dr. Breen was equipped with the accurate information – there is no mental health reporting requirement in her state’s medical license application – it might have saved her life.”

This same stigma was reflected in the survey, with one physician saying: “I’m afraid that if I spoke to a therapist, I’d have to report receiving psychiatric treatment to credentialing or licensing boards.” Roughly 40% of survey respondents, regardless of age, chose not to disclose their suicidal thoughts to anyone, not even a family member or suicide hotline. And just a tiny portion of physicians (10% of men and 13% of women) said that a colleague had discussed their suicidal thoughts with them.

“There is a longstanding culture of silence around physician mental health in the medical community,” said Dr. Price. “The strategies within the Act are critical to fixing this culture and making it acceptable and normalized for physicians to seek mental health care,” and for it to “become a fundamental and ongoing element of being a practicing physician.”

As part of the legislation, the Department of Health & Human Services must award grants to hospitals, medical associations, and other entities to facilitate mental health programs for providers. They must also establish policy recommendations and conduct campaigns to improve providers’ mental and behavioral health, encourage providers to seek mental health support and assistance, remove barriers to such treatment, and identify best practices to prevent suicide and promote resiliency
 

Addressing barriers to mental health

The new bill is a step in the right direction, but Dr. Price said health organizations must do more to address the six key structural barriers that are “discouraging physicians from seeking [mental health] help,” such as the inclusion of “intrusive mental health questions on medical board, hospital credentialing, and malpractice insurance applications.”

In addition, employers should allow physicians to seek out-of-network mental health services, if necessary, and not cause further humiliation by requiring them to be treated by colleagues within their hospital system. A similar proposal has recently been introduced and is gaining traction in Utah, following the suicide of ED physician Scott Jolley, MD, in 2021 after he was admitted for psychiatric care where he worked.

Diminishing the stigma surrounding physicians’ mental health encourages a more open dialogue, so if a colleague reaches out – listen. “Start by thanking the colleague for sharing the information: ‘I’m sure that wasn’t easy but I appreciate that you respect me enough to share this. Let’s talk more,’ ” said Michael F. Myers, MD, professor of clinical psychiatry at State University of New York, Brooklyn . “Then ask what you can do to help, which cuts down on the sense of isolation that colleague may feel.”

According to the survey, many physicians have developed strategies to support their happiness and mental health. Although fewer than 10% said reducing work hours or transitioning to a part-time schedule was most effective, the majority of physicians relied on spending time with family and friends (68%) – a choice that has considerable benefits.

“Close and intimate relationships are the single most protective factor for our mental health,” said Peter Yellowlees, MBBS, MD, chief wellness officer for UC Davis Health and professor of psychiatry at the University of California, Davis. “Isolation and loneliness are very important stressors, and we know that about 25% of the population reports being lonely.”
