A mother’s consumption of ultra-processed foods appears to be related to an increased risk of overweight or obesity in her children, according to new research.

Among the 19,958 mother-child pairs studied, 12.4% of children developed obesity or overweight in the full analytic study group, and the offspring of those mothers who ate the most ultra-processed foods had a 26% higher risk of obesity/overweight (12.1 servings/day), compared with those with the lowest consumption (3.4 servings/day), report Andrew T. Chan, MD, MPH, professor of medicine at Harvard Medical School, Boston, and colleagues.

This study demonstrates the possible advantages of restricting ultra-processed food consumption among women and mothers who are in their reproductive years to potentially lower the risk of childhood obesity, the investigators note.

“These data support the importance of refining dietary recommendations and the development of programs to improve nutrition for women of reproductive age to promote offspring health,” they write in their article, published in BMJ.

“As a medical and public health community, we have to understand that the period of time in which a woman is carrying a child or ... the time when she is raising her children represents a unique opportunity to potentially intervene to affect both the health of the mother and also the health of the children,” Dr. Chan said in an interview.

It is important to address these trends both on an individual clinician level and on a societal level, noted Dr. Chan.

“This is a good opportunity to counsel patients about the potential linkage between their consumption of ultra-processed food for not just themselves but also their kids, and I think that added counseling and awareness may motivate individuals to think about their diets in a more favorable way,” he added.

But ultra-processed foods are affordable and convenient, and many communities are not able to easily access fresh and healthy foods, so “it is incumbent upon [clinicians] to make it a priority and to break down those social and economic barriers, which make it difficult to have healthy and less processed food,” Dr. Chan elaborated.
 

Assessment of maternal junk food intake during peri-pregnancy and childhood

Modern Western diets frequently include ultra-processed foods – such as packaged baked goods and snacks, fizzy drinks, and sugary cereals – which are linked to adult weight increase. The relationship between parental consumption of highly processed meals and offspring weight is, however, unclear across generations, the researchers note.

Hence, they set out to determine whether eating ultra-processed foods during peri-pregnancy and while raising children increased the risk of being overweight or having obesity among children and teens.

The study team assessed 14,553 mothers and their 19,958 children from the Growing Up Today Study (GUTS I and II) and Nurses’ Health Study II (NHS II) in the United States. Males accounted for 45% of the children in the study, and the children’s ages ranged from 7 to 17 years.

The NHS II is a continuing investigation following the lifestyle and health choices of over 100,000 female registered nurses in the United States in 1989, while the GUTS I involved about 17,000 children of the nurses in the NHS II. Participants in GUTS I filled out an initial lifestyle and health survey and were evaluated annually between 1997 and 2001 and every 2 years thereafter.  

Roughly 11,000 children from the NHS II were included in the GUTS II. The children were further evaluated in 2006, 2008, and 2011, as well as every 2 years thereafter.

Participants were followed until the children reached 18 years of age or experienced obesity and overweight onset. A subcohort consisted of 2,925 mother-child pairs with data on peri-pregnancy eating patterns.

Maternal intake of ultra-processed foods while raising children was linked with obesity or overweight in children. Moreover, compared with the lowest consumption cohort (3.4 servings/day), there was a 26% greater risk for the greatest maternal ultra-processed food intake cohort (12.1 servings/day) after adjusting for child’s sedentary time, ultra-processed food intake, physical activity, and established maternal risk factors.

Even though rates were elevated, ultra-processed food intake during pregnancy was not significantly linked to a higher risk of obesity or overweight in children (P for trend = .07).

Sex, birth weight, age, gestational age, or maternal body weight had no effect on these correlations either.

The study’s limitations include the fact that some of the children in the pairs were lost during follow-up; there may have been data misreporting, as the weight and diet measures were provided via self-reported questionnaires; and potential residual confounding given the observational study design, the researchers note.

Other limitations include that the mothers involved in the study came from similar socioeconomic backgrounds, had similar personal and familial educational statuses, and were primarily White, which limits the generalizability of these data to other ethnic groups, the authors add.

“Further studies are warranted to investigate specific biological mechanisms and socioeconomic determinants underlying the observed associations between maternal ultra-processed food intake and offspring overweight and obesity,” the researchers conclude.

Long-term antidepressant use is tied to an increased risk of adverse outcomes, including cardiovascular disease (CVD), cerebrovascular disease, coronary heart disease (CHD), and all-cause mortality, new research suggests.

The investigators drew on 10-year data from the UK Biobank on over 220,000 adults and compared the risk of developing adverse health outcomes among those taking antidepressants with the risk among those who were not taking antidepressants.

After adjusting for preexisting risk factors, they found that 10-year antidepressant use was associated with a twofold higher risk of CHD, an almost-twofold higher risk of CVD as well as CVD mortality, a higher risk of cerebrovascular disease, and more than double the risk of all-cause mortality.

On the other hand, at 10 years, antidepressant use was associated with a 23% lower risk of developing hypertension and a 32% lower risk of diabetes.

The main culprits were mirtazapine, venlafaxine, duloxetine, and trazodone, although SSRIs were also tied to increased risk.

“Our message for clinicians is that prescribing of antidepressants in the long term may not be harm free [and] we hope that this study will help doctors and patients have more informed conversations when they weigh up the potential risks and benefits of treatments for depression,” study investigator Narinder Bansal, MD, honorary research fellow, Centre for Academic Health and Centre for Academic Primary Care, University of Bristol (England), said in a news release.

“Regardless of whether the drugs are the underlying cause of these problems, our findings emphasize the importance of proactive cardiovascular monitoring and prevention in patients who have depression and are on antidepressants, given that both have been associated with higher risks,” she added.

The study was published online in the British Journal of Psychiatry Open.
 

Monitoring of CVD risk ‘critical’

Antidepressants are among the most widely prescribed drugs; 70 million prescriptions were dispensed in 2018 alone, representing a doubling of prescriptions for these agents in a decade, the investigators noted. “This striking rise in prescribing is attributed to long-term treatment rather than an increased incidence of depression.”

Most trials that have assessed antidepressant efficacy have been “poorly suited to examining adverse outcomes.” One reason for this is that many of the trials are short-term studies. Since depression is “strongly associated” with CVD risk factors, “careful assessment of the long-term cardiometabolic effects of antidepressant treatment is critical.”

Moreover, information about “a wide range of prospectively measured confounders ... is needed to provide robust estimates of the risks associated with long-term antidepressant use,” the authors noted.

The researchers examined the association between antidepressant use and four cardiometabolic morbidity outcomes – diabetes, hypertension, cerebrovascular disease, and CHD. In addition, they assessed two mortality outcomes – CVD mortality and all-cause mortality. Participants were divided into cohorts on the basis of outcome of interest.

The dataset contains detailed information on socioeconomic status, demographics, anthropometric, behavioral, and biochemical risk factors, disability, and health status and is linked to datasets of primary care records and deaths.

The study included 222,121 participants whose data had been linked to primary care records during 2018 (median age of participants, 56-57 years). About half were women, and 96% were of White ethnicity.

Participants were excluded if they had been prescribed antidepressants 12 months or less before baseline, if they had previously been diagnosed for the outcome of interest, if they had been previously prescribed psychotropic drugs, if they used cardiometabolic drugs at baseline, or if they had undergone treatment with antidepressant polytherapy.

Potential confounders included age, gender, body mass index, waist/hip ratio, smoking and alcohol intake status, physical activity, parental history of outcome, biochemical and hematologic biomarkers, socioeconomic status, and long-term illness, disability, or infirmity.
 

Mechanism unclear

By the end of the 5- and 10-year follow-up periods, an average of 8% and 6% of participants in each cohort, respectively, had been prescribed an antidepressant. SSRIs constituted the most commonly prescribed class (80%-82%), and citalopram was the most commonly prescribed SSRI (46%-47%). Mirtazapine was the most frequently prescribed non-SSRI antidepressant (44%-46%).

At 5 years, any antidepressant use was associated with an increased risk for diabetes, CHD, and all-cause mortality, but the findings were attenuated after further adjustment for confounders. In fact, SSRIs were associated with a reduced risk of diabetes at 5 years (hazard ratio, 0.64; 95% confidence interval, 0.49-0.83).

At 10 years, SSRIs were associated with an increased risk of cerebrovascular disease, CVD mortality, and all-cause mortality; non-SSRIs were associated with an increased risk of CHD, CVD, and all-cause mortality.

On the other hand, SSRIs were associated with a decrease in risk of diabetes and hypertension at 10 years (HR, 0.68; 95% CI, 0.53-0.87; and HR, 0.77; 95% CI, 0.66-0.89, respectively).

“While we have taken into account a wide range of pre-existing risk factors for cardiovascular disease, including those that are linked to depression such as excess weight, smoking, and low physical activity, it is difficult to fully control for the effects of depression in this kind of study, partly because there is considerable variability in the recording of depression severity in primary care,” said Dr. Bansal.

“This is important because many people taking antidepressants such as mirtazapine, venlafaxine, duloxetine and trazodone may have a more severe depression. This makes it difficult to fully separate the effects of the depression from the effects of medication,” she said.

Further research “is needed to assess whether the associations we have seen are genuinely due to the drugs; and, if so, why this might be,” she added.
 

Strengths, limitations

Commenting on the study, Roger McIntyre, MD, professor of psychiatry and pharmacology and head of the mood disorders psychopharmacology unit at the University of Toronto,, discussed the strengths and weaknesses of the study.

The UK Biobank is a “well-described, well-phenotyped dataset of good quality,” said Dr. McIntyre, chairperson and executive director of the Brain and Cognitive Discover Foundation, Toronto, who was not involved with the study. Another strength is the “impressive number of variables the database contains, which enabled the authors to go much deeper into the topics.”

A “significant limitation” is the confounding that is inherent to the disorder itself – “people with depression have a much higher intrinsic risk of CVD, [cerebrovascular disease], and cardiovascular mortality,” Dr. McIntyre noted.

The researchers did not adjust for trauma or childhood maltreatment, “which are the biggest risk factors for both depression and CVD; and drug and alcohol misuse were also not accounted for.”

Additionally, “to determine whether something is an association or potentially causative, it must satisfy the Bradford-Hill criteria,” said Dr. McIntyre. “Since we’re moving more toward using these big databases and because we depend on them to give us long-term perspectives, we would want to see coherent, compelling Bradford-Hill criteria regarding causation. If you don’t have any, that’s fine too, but then it’s important to make clear that there is no clear causative line, just an association.”

The research was funded by the National Institute of Health Research School for Primary Care Research and was supported by the NI Biomedical Research Centre at University Hospitals Bristol and Weston NHS Foundation Trust and the University of Bristol. Dr. McIntyre has received research grant support from CI/GACD/National Natural Science Foundation of China and the Milken Institute and speaker/consultation fees from numerous companies.

At 5 years, any antidepressant use was associated with an increased risk for diabetes, CHD, and all-cause mortality, but the findings were attenuated after further adjustment for confounders. In fact, SSRIs were associated with a reduced risk of diabetes at 5 years (hazard ratio, 0.64; 95% confidence interval, 0.49-0.83).

At 10 years, SSRIs were associated with an increased risk of cerebrovascular disease, CVD mortality, and all-cause mortality; non-SSRIs were associated with an increased risk of CHD, CVD, and all-cause mortality.

On the other hand, SSRIs were associated with a decrease in risk of diabetes and hypertension at 10 years (HR, 0.68; 95% CI, 0.53-0.87; and HR, 0.77; 95% CI, 0.66-0.89, respectively).

“While we have taken into account a wide range of pre-existing risk factors for cardiovascular disease, including those that are linked to depression such as excess weight, smoking, and low physical activity, it is difficult to fully control for the effects of depression in this kind of study, partly because there is considerable variability in the recording of depression severity in primary care,” said Dr. Bansal.

“This is important because many people taking antidepressants such as mirtazapine, venlafaxine, duloxetine and trazodone may have a more severe depression. This makes it difficult to fully separate the effects of the depression from the effects of medication,” she said.

Further research “is needed to assess whether the associations we have seen are genuinely due to the drugs; and, if so, why this might be,” she added.
 

Strengths, limitations

Commenting on the study, Roger McIntyre, MD, professor of psychiatry and pharmacology and head of the mood disorders psychopharmacology unit at the University of Toronto,, discussed the strengths and weaknesses of the study.

The UK Biobank is a “well-described, well-phenotyped dataset of good quality,” said Dr. McIntyre, chairperson and executive director of the Brain and Cognitive Discover Foundation, Toronto, who was not involved with the study. Another strength is the “impressive number of variables the database contains, which enabled the authors to go much deeper into the topics.”

A “significant limitation” is the confounding that is inherent to the disorder itself – “people with depression have a much higher intrinsic risk of CVD, [cerebrovascular disease], and cardiovascular mortality,” Dr. McIntyre noted.

The researchers did not adjust for trauma or childhood maltreatment, “which are the biggest risk factors for both depression and CVD; and drug and alcohol misuse were also not accounted for.”

Additionally, “to determine whether something is an association or potentially causative, it must satisfy the Bradford-Hill criteria,” said Dr. McIntyre. “Since we’re moving more toward using these big databases and because we depend on them to give us long-term perspectives, we would want to see coherent, compelling Bradford-Hill criteria regarding causation. If you don’t have any, that’s fine too, but then it’s important to make clear that there is no clear causative line, just an association.”

The research was funded by the National Institute of Health Research School for Primary Care Research and was supported by the NI Biomedical Research Centre at University Hospitals Bristol and Weston NHS Foundation Trust and the University of Bristol. Dr. McIntyre has received research grant support from CI/GACD/National Natural Science Foundation of China and the Milken Institute and speaker/consultation fees from numerous companies. Dr. McIntyre is a CEO of Braxia Scientific.

Unlike for many other professions, there is no age limit for practicing medicine. According to international standards, airplane pilots, for example, who are responsible for the safety of many human lives, must retire by the age of 60 if they work alone, or 65 if they have a copilot. In Brazil, however, this age limit does not exist for pilots or physicians.

The only restriction on professional practice within the medical context is the mandatory retirement imposed on medical professors who teach at public (state and federal) universities, starting at the age of 75. Nevertheless, these professionals can continue practicing administrative and research-related activities. After “expulsion,” as this mandatory retirement is often called, professors who stood out or contributed to the institution and science may receive the title of professor emeritus.

In the private sector, age limits are not formally set, but the hiring of middle-aged professionals is limited.

At the Heart Institute of the University of São Paulo (Brazil) School of Medicine Clinical Hospital (InCor/HCFMUSP), one of the world’s largest teaching and research centers for cardiovascular and pulmonary diseases, several octogenarian specialists lead studies and teams. One of these is Noedir Stolf, MD, an 82-year-old cardiovascular surgeon who operates almost every day and coordinates studies on transplants, mechanical circulatory support, and aortic surgery. There is also Protásio Lemos da Luz, MD, an 82-year-old clinical cardiologist who guides research on subjects including atherosclerosis, the endothelium, microbiota, and diabetes. The protective effect of wine on atherosclerosis is one of his best-known studies.

No longer working is also not in the cards for Angelita Habr-Gama, MD, who, at 89 years old, is one of the oldest physicians in current practice. With a career spanning more than 7 decades, she is a world reference in coloproctology. She was the first woman to become a surgical resident at the HCFMUSP, where she later founded the coloproctology specialty and created the first residency program for the specialty. In April 2022, Dr. Habr-Gama joined the ranks of the 100 most influential scientists in the world, nominated by researchers at Stanford (Calif.) University, and published in PLOS Biology.

In 2020, she was sedated, intubated, and hospitalized in the intensive care unit of the Oswaldo Cruz German Hospital for 54 days because of a SARS-CoV-2 infection. After her discharge, she went back to work in less than 10 days – and added chess classes to her routine. “To get up and go to work makes me very happy. Work is my greatest hobby. No one has ever heard me complain about my life,” Dr. Habr-Gama told this news organization after having rescheduled the interview twice because of emergency surgeries.

“Doctors have a professional longevity that does not exist for other professions in which the person retires and stops practicing their profession or goes on to do something else for entertainment. Doctors can retire from one place of employment or public practice and continue practicing medicine in the office as an administrator or consultant,” Ângelo Vattimo, first secretary of the state of São Paulo Regional Board of Medicine (CREMESP), stated. The board regularly organizes a ceremony to honor professionals who have been practicing for 50 years, awarding them a certificate and engraved medal. “Many of them are around 80 years old, working and teaching. This always makes us very happy. What profession has such exceptional compliance for so long?” said Mr. Vattimo.

In the medical field, the older the age range, the smaller the number of women. According to the 2020 Medical Demographics in Brazil survey, only 2 out of 10 practicing professionals older than 70 are women.

Not everyone over 80 has Dr. Habr-Gama’s vitality, because the impact of aging is not equal. “If you look at a group of 80-year-olds, there will be much more variability than within a group of 40-year-olds,” stated Mark Katlic, MD, chief of surgery at LifeBridge Health System in the United States, who has dedicated his life to studying the subject. Dr. Katlic spoke on the subject in an interview that was published in the article “How Old Is Too Old to Work as a Doctor?” published by this news organization in April of 2022. The article discusses the evaluations of elderly physicians’ skills and competences that U.S. companies conduct. The subject has been leading to profound debate.

Dr. Katlic defends screening programs for elderly physicians, which already are in effect at the company for which he works, LifeBridge Health, and various others in the United States. “We do [screen elderly physicians at LifeBridge Health], and so do a few dozen other [U.S. institutions], but there are hundreds [of health care institutions] that do not conduct this screening,” he pointed out.

Age-related assessment faces great resistance in the United States. One physician who is against the initiative is Frank Stockdale, MD, PhD, an 86-year-old practicing oncologist affiliated with Stanford (Calif.) University Health. “It’s age discrimination ... Physicians [in the United States] receive assessments throughout their careers as part of the accreditation process – there’s no need to change that as physicians reach a certain age,” Dr. Stockdale told this news organization.

The U.S. initiative of instituting physician assessment programs for those of a certain age has even been tested in court. According to an article published in Medscape, “in New Haven, Connecticut, for instance, the U.S. Equal Employment Opportunity Commission (EEOC) filed a suit in 2020 on behalf of the Yale New Haven Hospital staff, alleging a discriminatory late career practitioner policy.”

Also, according to the article, a similar case in Minnesota reached a settlement in 2021, providing monetary relief to staff impacted by out-of-pocket costs for the assessment, in addition to requiring that the hospital in question report to the EEOC any complaints related to age discrimination.

The fact is that increased life expectancy and, subsequently, the number of middle-aged physicians in practice, has raised several questions regarding the impact of aging on professional practice. In Brazil, the subject is of interest to more than 34,571 physicians between 65 and 69 years of age and 34,237 physicians older than 70. In all, this population represents approximately 14.3% of the country’s active workforce, according to the 2020 Medical Demographics in Brazil survey.

The significant participation of health care professionals over age 50 in a survey conducted by this news organization to learn what physicians think about the age limit for practicing their professions is evidence that the subject is a present concern. Of a total of 1,641 participants, 57% were age 60 or older, 17% were between 50 and 59 years, and 12% were between 40 and 49 years. Among all participants, 51% were against these limitations, 17% approved of the idea for all specialties, and 32% believed the restriction was appropriate only for some specialties. Regarding the possibility of older physicians undergoing regular assessments, the opinions were divided: Thirty-one percent thought they should be assessed in all specialties. Furthermore, 31% believed that cognitive abilities should be regularly tested in all specialties, 31% thought this should take place for some specialties, and 38% were against this approach.

Professionals want to know, for example, how (and whether) advanced age can interfere with performance, what are the competences required to practice their activities, and if the criteria vary by specialty. “A psychiatrist doesn’t have to have perfect visual acuity, as required from a dermatologist, but it is important that they have good hearing, for example,” argued Clóvis Constantino, MD, former president of the São Paulo Regional Medical Board (CRM-SP) and former vice president of the Brazilian Federal Medical Board (CFM). “However, a surgeon has to stand for several hours in positions that may be uncomfortable. It’s not easy,” he told this news organization.

In the opinion of 82-year-old Henrique Klajner, MD, the oldest pediatrician in practice at the Albert Einstein Israeli Hospital in São Paulo, the physician cannot be subjected to the types of evaluations that have been applied in the United States. “Physicians should conduct constant self-evaluations to see if they have the competences and skills needed to practice their profession ... Moreover, this is not a matter of age. It is a matter of ethics,” said Dr. Klajner.

The ability to adapt to change and implement innovation is critical to professional longevity, he said. “Nowadays, when I admit patients, I no longer do hospital rounds, which requires a mobility equal to physical abuse for me. Therefore, I work with physicians who take care of my hospitalized patients.”

Dr. Klajner also feels there is a distinction between innovations learned through studies and what can be offered safely to patients. “If I have to care for a hospitalized patient with severe pneumonia, for example, since I am not up to date in this specialty, I am going to call upon a pulmonologist I trust and forgo my honorarium for this admission. But I will remain on the team, monitoring the patient’s progression,” he said.

During the COVID-19 pandemic, Dr. Klajner stopped seeing patients in person under the recommendation of his son, Sidney Klajner, MD, also a physician. The elder Dr. Klajner began exploring telemedicine, which opened a whole new world of possibilities. “I have conducted several online visits to provide educational instruction to mothers returning home post delivery, for example,” he told this news organization. The time to stop is not something that concerns Dr. Klajner. “I’m only going to stop when I have a really important reason to do so. For example, if I can no longer write or study, reading and rereading an article without being able to understand what is being said. At this time, none of that is happening.”

In the United States, as well as in Brazil, physicians rarely provide information to human resources departments on colleagues showing signs of cognitive or motor decline affecting their professional performance. “The expectation is that health care professionals will report colleagues with cognitive impairments, but that often does not happen,” Dr. Katlic said.

It is also not common for professionals to report their own deficits to their institutions. In large part, this is caused by a lack of well-defined policies for dealing with this issue. This news organization sought out several public and private hospitals in Brazil to see if there is any guidance on professional longevity: Most said that there is not. Only the A. C. Camargo Cancer Center reported, through its public relations team, that a committee is discussing the subject but that it is still in the early stages.

Brazilian specialist associations do not offer guidelines or instructions on the various aspects of professional longevity. Dr. Constantino tried to put the subject on the agenda during the years in which he was an administrator with the CFM. “We tried to open up discussions regarding truly elderly physicians, but the subject was not well received. I believe that it is precisely because there is a tradition of physicians working until they are no longer able that this is more difficult in Brazil ... No one exactly knows what to do in this respect.” Dr. Constantino is against the use of age as a criterion for quitting practice.

“Of course, this is a point that has to be considered, but I always defended the need for regular assessment of physicians, regardless of age range. And, although assessments are always welcome, in any profession, I also believe this would not be well received in Brazil.” He endorses an assessment of one’s knowledge and not of physical abilities, which are generally assessed through investigation when needed.

The absence of guidelines increases individual responsibility, as well as vulnerability. “Consciously, physicians will not put patients at risk if they do not have the competence to care for them or to perform a surgical procedure,” said Clystenes Odyr Soares Silva, MD, PhD, adjunct professor of pulmonology of the Federal University of São Paulo (Brazil) School of Medicine (UNIFESP). “Your peers will tell you if you are no longer able,” he added. The problem is that physicians rarely admit to or talk about their colleagues’ deficits, especially if they are in the spotlight because of advanced age. In this situation, the observation and opinion of family members regarding the health care professional’s competences and skills will hold more weight.

In case of health-related physical impairment, such as partial loss of hand movement, for example, “it is expected that this will set off an ethical warning in the person,” said Dr. Constantino. When this warning does not occur naturally, patients or colleagues can report the professional, and this may lead to the opening of an administrative investigation. If the report is found to be true, this investigation is used to suspend physicians who do not have the physical or mental ability to continue practicing medicine.

“If it’s something very serious, the physician’s license can be temporarily suspended while [the physician] is treated by a psychiatrist, with follow-up by the professional board. When discharged, the physician will get his or her [professional] license back and can go back to work,” Dr. Constantino explained. If an expert evaluation is needed, the physician will then be assessed by a forensic psychiatrist. One of the most in-demand forensic psychiatrists in Brazil is Guido Arturo Palomba, MD, 73 years old. “I have assessed some physicians for actions reported to see if they were normal people or not, but never for circumstances related to age,” Dr. Palomba said.

In practice, Brazilian medical entities do not have policies or programs to guide physicians who wish to grow old while they work or those who have started to notice they are not performing as they used to. “We have never lived as long; therefore, the quality of life in old age, as well as the concept of aging, are some of the most relevant questions of our time. These are subjects requiring additional discussion, broadening understanding and awareness in this regard,” observed Mr. Vattimo.

Dr. Constantino and Dr. Silva, who are completely against age-based assessments, believe that recertification of the specialist license every 5 years is the best path to confirming whether the physician is still able to practice. “A knowledge-based test every 5 years to recertify the specialist license has often been a topic of conversation. I think it’s an excellent idea. The person would provide a dossier of all they have done in terms of courses, conferences, and other activities, present it, and receive a score,” said Dr. Silva.

In practice, recertification of the specialist license is a topic of discussion that has been raised for years, and it is an idea that the Brazilian Medical Association (AMB) defends. In conjunction with the CFM, the association is studying a way to best implement this assessment. “It’s important to emphasize that this measure would not be retroactive at first. Instead, it would only be in effect for professionals licensed after the recertification requirement is established,” the AMB pointed out in a note sent to this news organization. Even so, the measure has faced significant resistance from a faction of the profession, and its enactment does not seem to be imminent.

The debate regarding professional longevity is taking place in various countries. In 2021, the American Medical Association Council on Medical Education released a report with a set of guidelines for the screening and assessment of physicians. The document is the product of a committee created in 2015 to study the subject. The AMA recommends that the assessment of elderly physicians be based on evidence and ethical, relevant, fair, equitable, transparent, verifiable, nonexhaustive principles, contemplating support and protecting against legal proceedings. In April of this year, a new AMA document highlighted the same principles.

Also in the United States, one of oldest initiatives created to support physicians in the process of recycling, the University of California San Diego Physician Assessment and Clinical Education Program (PACE), has a section focusing on the extended practice of medicine (Practicing Medicine Longer). For those wanting to learn more about discussions on this subject, there are online presentations on experiences in Quebec and Ontario with assessing aging physicians, neuropsychological perspectives on the aging medical population, and what to expect of healthy aging, among other subjects.

Created in 1996, PACE mostly provides services to physicians who need to address requirements of the state medical boards. Few physicians enroll on their own.

The first part of the program assesses knowledge and skills over approximately 2 days. In the second phase, the physician participates in a series of activities in a corresponding residency program. Depending on the results, the physician may have to go through a remedial program with varying activities to deal with performance deficiencies to clinical experiences at the residency level.

The AMA recommends that the assessment of elderly physicians be based on evidence and ethical, relevant, fair, equitable, transparent, verifiable, nonexhaustive principles, contemplating support and protecting against legal proceedings. In April of this year, a new AMA document highlighted the same principles.

Also in the United States, one of oldest initiatives created to support physicians in the process of recycling, the University of California San Diego Physician Assessment and Clinical Education Program (PACE), has a section focusing on the extended practice of medicine (Practicing Medicine Longer). For those wanting to learn more about discussions on this subject, there are online presentations on experiences in Quebec and Ontario with assessing aging physicians, neuropsychological perspectives on the aging medical population, and what to expect of healthy aging, among other subjects.

Created in 1996, PACE mostly provides services to physicians who need to address requirements of the state medical boards. Few physicians enroll on their own.

The first part of the program assesses knowledge and skills over approximately 2 days. In the second phase, the physician participates in a series of activities in a corresponding residency program. Depending on the results, the physician may have to go through a remedial program with varying activities to deal with performance deficiencies to clinical experiences at the residency level.

Unlike for many other professions, there is no age limit for practicing medicine. According to international standards, airplane pilots, for example, who are responsible for the safety of many human lives, must retire by the age of 60 if they work alone, or 65 if they have a copilot. In Brazil, however, this age limit does not exist for pilots or physicians.

The only restriction on professional practice within the medical context is the mandatory retirement imposed on medical professors who teach at public (state and federal) universities, starting at the age of 75. Nevertheless, these professionals can continue practicing administrative and research-related activities. After “expulsion,” as this mandatory retirement is often called, professors who stood out or contributed to the institution and science may receive the title of professor emeritus.

In the private sector, age limits are not formally set, but the hiring of middle-aged professionals is limited.

At the Heart Institute of the University of São Paulo (Brazil) School of Medicine Clinical Hospital (InCor/HCFMUSP), one of the world’s largest teaching and research centers for cardiovascular and pulmonary diseases, several octogenarian specialists lead studies and teams. One of these is Noedir Stolf, MD, an 82-year-old cardiovascular surgeon who operates almost every day and coordinates studies on transplants, mechanical circulatory support, and aortic surgery. There is also Protásio Lemos da Luz, MD, an 82-year-old clinical cardiologist who guides research on subjects including atherosclerosis, the endothelium, microbiota, and diabetes. The protective effect of wine on atherosclerosis is one of his best-known studies.

No longer working is also not in the cards for Angelita Habr-Gama, MD, who, at 89 years old, is one of the oldest physicians in current practice. With a career spanning more than 7 decades, she is a world reference in coloproctology. She was the first woman to become a surgical resident at the HCFMUSP, where she later founded the coloproctology specialty and created the first residency program for the specialty. In April 2022, Dr. Habr-Gama joined the ranks of the 100 most influential scientists in the world, nominated by researchers at Stanford (Calif.) University, and published in PLOS Biology.

In 2020, she was sedated, intubated, and hospitalized in the intensive care unit of the Oswaldo Cruz German Hospital for 54 days because of a SARS-CoV-2 infection. After her discharge, she went back to work in less than 10 days – and added chess classes to her routine. “To get up and go to work makes me very happy. Work is my greatest hobby. No one has ever heard me complain about my life,” Dr. Habr-Gama told this news organization after having rescheduled the interview twice because of emergency surgeries.

“Doctors have a professional longevity that does not exist for other professions in which the person retires and stops practicing their profession or goes on to do something else for entertainment. Doctors can retire from one place of employment or public practice and continue practicing medicine in the office as an administrator or consultant,” Ângelo Vattimo, first secretary of the state of São Paulo Regional Board of Medicine (CREMESP), stated. The board regularly organizes a ceremony to honor professionals who have been practicing for 50 years, awarding them a certificate and engraved medal. “Many of them are around 80 years old, working and teaching. This always makes us very happy. What profession has such exceptional compliance for so long?” said Mr. Vattimo.

In the medical field, the older the age range, the smaller the number of women. According to the 2020 Medical Demographics in Brazil survey, only 2 out of 10 practicing professionals older than 70 are women.

Not everyone over 80 has Dr. Habr-Gama’s vitality, because the impact of aging is not equal. “If you look at a group of 80-year-olds, there will be much more variability than within a group of 40-year-olds,” stated Mark Katlic, MD, chief of surgery at LifeBridge Health System in the United States, who has dedicated his life to studying the subject. Dr. Katlic spoke on the subject in an interview that was published in the article “How Old Is Too Old to Work as a Doctor?” published by this news organization in April of 2022. The article discusses the evaluations of elderly physicians’ skills and competences that U.S. companies conduct. The subject has been leading to profound debate.

Dr. Katlic defends screening programs for elderly physicians, which already are in effect at the company for which he works, LifeBridge Health, and various others in the United States. “We do [screen elderly physicians at LifeBridge Health], and so do a few dozen other [U.S. institutions], but there are hundreds [of health care institutions] that do not conduct this screening,” he pointed out.

Age-related assessment faces great resistance in the United States. One physician who is against the initiative is Frank Stockdale, MD, PhD, an 86-year-old practicing oncologist affiliated with Stanford (Calif.) University Health. “It’s age discrimination ... Physicians [in the United States] receive assessments throughout their careers as part of the accreditation process – there’s no need to change that as physicians reach a certain age,” Dr. Stockdale told this news organization.

The U.S. initiative of instituting physician assessment programs for those of a certain age has even been tested in court. According to an article published in Medscape, “in New Haven, Connecticut, for instance, the U.S. Equal Employment Opportunity Commission (EEOC) filed a suit in 2020 on behalf of the Yale New Haven Hospital staff, alleging a discriminatory late career practitioner policy.”

Also, according to the article, a similar case in Minnesota reached a settlement in 2021, providing monetary relief to staff impacted by out-of-pocket costs for the assessment, in addition to requiring that the hospital in question report to the EEOC any complaints related to age discrimination.

The fact is that increased life expectancy and, subsequently, the number of middle-aged physicians in practice, has raised several questions regarding the impact of aging on professional practice. In Brazil, the subject is of interest to more than 34,571 physicians between 65 and 69 years of age and 34,237 physicians older than 70. In all, this population represents approximately 14.3% of the country’s active workforce, according to the 2020 Medical Demographics in Brazil survey.

The significant participation of health care professionals over age 50 in a survey conducted by this news organization to learn what physicians think about the age limit for practicing their professions is evidence that the subject is a present concern. Of a total of 1,641 participants, 57% were age 60 or older, 17% were between 50 and 59 years, and 12% were between 40 and 49 years. Among all participants, 51% were against these limitations, 17% approved of the idea for all specialties, and 32% believed the restriction was appropriate only for some specialties. Regarding the possibility of older physicians undergoing regular assessments, the opinions were divided: Thirty-one percent thought they should be assessed in all specialties. Furthermore, 31% believed that cognitive abilities should be regularly tested in all specialties, 31% thought this should take place for some specialties, and 38% were against this approach.

Professionals want to know, for example, how (and whether) advanced age can interfere with performance, what are the competences required to practice their activities, and if the criteria vary by specialty. “A psychiatrist doesn’t have to have perfect visual acuity, as required from a dermatologist, but it is important that they have good hearing, for example,” argued Clóvis Constantino, MD, former president of the São Paulo Regional Medical Board (CRM-SP) and former vice president of the Brazilian Federal Medical Board (CFM). “However, a surgeon has to stand for several hours in positions that may be uncomfortable. It’s not easy,” he told this news organization.

In the opinion of 82-year-old Henrique Klajner, MD, the oldest pediatrician in practice at the Albert Einstein Israeli Hospital in São Paulo, the physician cannot be subjected to the types of evaluations that have been applied in the United States. “Physicians should conduct constant self-evaluations to see if they have the competences and skills needed to practice their profession ... Moreover, this is not a matter of age. It is a matter of ethics,” said Dr. Klajner.

The ability to adapt to change and implement innovation is critical to professional longevity, he said. “Nowadays, when I admit patients, I no longer do hospital rounds, which requires a mobility equal to physical abuse for me. Therefore, I work with physicians who take care of my hospitalized patients.”

Dr. Klajner also feels there is a distinction between innovations learned through studies and what can be offered safely to patients. “If I have to care for a hospitalized patient with severe pneumonia, for example, since I am not up to date in this specialty, I am going to call upon a pulmonologist I trust and forgo my honorarium for this admission. But I will remain on the team, monitoring the patient’s progression,” he said.

During the COVID-19 pandemic, Dr. Klajner stopped seeing patients in person under the recommendation of his son, Sidney Klajner, MD, also a physician. The elder Dr. Klajner began exploring telemedicine, which opened a whole new world of possibilities. “I have conducted several online visits to provide educational instruction to mothers returning home post delivery, for example,” he told this news organization. The time to stop is not something that concerns Dr. Klajner. “I’m only going to stop when I have a really important reason to do so. For example, if I can no longer write or study, reading and rereading an article without being able to understand what is being said. At this time, none of that is happening.”

In the United States, as well as in Brazil, physicians rarely provide information to human resources departments on colleagues showing signs of cognitive or motor decline affecting their professional performance. “The expectation is that health care professionals will report colleagues with cognitive impairments, but that often does not happen,” Dr. Katlic said.

It is also not common for professionals to report their own deficits to their institutions. In large part, this is caused by a lack of well-defined policies for dealing with this issue. This news organization sought out several public and private hospitals in Brazil to see if there is any guidance on professional longevity: Most said that there is not. Only the A. C. Camargo Cancer Center reported, through its public relations team, that a committee is discussing the subject but that it is still in the early stages.

Brazilian specialist associations do not offer guidelines or instructions on the various aspects of professional longevity. Dr. Constantino tried to put the subject on the agenda during the years in which he was an administrator with the CFM. “We tried to open up discussions regarding truly elderly physicians, but the subject was not well received. I believe that it is precisely because there is a tradition of physicians working until they are no longer able that this is more difficult in Brazil ... No one exactly knows what to do in this respect.” Dr. Constantino is against the use of age as a criterion for quitting practice.

“Of course, this is a point that has to be considered, but I always defended the need for regular assessment of physicians, regardless of age range. And, although assessments are always welcome, in any profession, I also believe this would not be well received in Brazil.” He endorses an assessment of one’s knowledge and not of physical abilities, which are generally assessed through investigation when needed.

The absence of guidelines increases individual responsibility, as well as vulnerability. “Consciously, physicians will not put patients at risk if they do not have the competence to care for them or to perform a surgical procedure,” said Clystenes Odyr Soares Silva, MD, PhD, adjunct professor of pulmonology of the Federal University of São Paulo (Brazil) School of Medicine (UNIFESP). “Your peers will tell you if you are no longer able,” he added. The problem is that physicians rarely admit to or talk about their colleagues’ deficits, especially if they are in the spotlight because of advanced age. In this situation, the observation and opinion of family members regarding the health care professional’s competences and skills will hold more weight.

In case of health-related physical impairment, such as partial loss of hand movement, for example, “it is expected that this will set off an ethical warning in the person,” said Dr. Constantino. When this warning does not occur naturally, patients or colleagues can report the professional, and this may lead to the opening of an administrative investigation. If the report is found to be true, this investigation is used to suspend physicians who do not have the physical or mental ability to continue practicing medicine.

“If it’s something very serious, the physician’s license can be temporarily suspended while [the physician] is treated by a psychiatrist, with follow-up by the professional board. When discharged, the physician will get his or her [professional] license back and can go back to work,” Dr. Constantino explained. If an expert evaluation is needed, the physician will then be assessed by a forensic psychiatrist. One of the most in-demand forensic psychiatrists in Brazil is Guido Arturo Palomba, MD, 73 years old. “I have assessed some physicians for actions reported to see if they were normal people or not, but never for circumstances related to age,” Dr. Palomba said.

In practice, Brazilian medical entities do not have policies or programs to guide physicians who wish to grow old while they work or those who have started to notice they are not performing as they used to. “We have never lived as long; therefore, the quality of life in old age, as well as the concept of aging, are some of the most relevant questions of our time. These are subjects requiring additional discussion, broadening understanding and awareness in this regard,” observed Mr. Vattimo.

Dr. Constantino and Dr. Silva, who are completely against age-based assessments, believe that recertification of the specialist license every 5 years is the best path to confirming whether the physician is still able to practice. “A knowledge-based test every 5 years to recertify the specialist license has often been a topic of conversation. I think it’s an excellent idea. The person would provide a dossier of all they have done in terms of courses, conferences, and other activities, present it, and receive a score,” said Dr. Silva.

In practice, recertification of the specialist license is a topic of discussion that has been raised for years, and it is an idea that the Brazilian Medical Association (AMB) defends. In conjunction with the CFM, the association is studying a way to best implement this assessment. “It’s important to emphasize that this measure would not be retroactive at first. Instead, it would only be in effect for professionals licensed after the recertification requirement is established,” the AMB pointed out in a note sent to this news organization. Even so, the measure has faced significant resistance from a faction of the profession, and its enactment does not seem to be imminent.

The debate regarding professional longevity is taking place in various countries. In 2021, the American Medical Association Council on Medical Education released a report with a set of guidelines for the screening and assessment of physicians. The document is the product of a committee created in 2015 to study the subject. The AMA recommends that the assessment of elderly physicians be based on evidence and ethical, relevant, fair, equitable, transparent, verifiable, nonexhaustive principles, contemplating support and protecting against legal proceedings.

New research suggests there may be better times during the day for eating and fasting. 

Eating earlier in the day may help you lose weight, and eating meals within a 10-hour window could improve blood sugar and cholesterol levels, according to two new studies published in Cell Metabolism.

“You have this internal biological clock that makes you better at doing different things at different times of the day,” Courtney Peterson, PhD, an associate professor of nutrition sciences at the University of Alabama at Birmingham, told NBC News. Dr. Peterson wasn’t involved with the studies.

“It seems like the best time for your metabolism, in most people, is the mid to late morning,” she said.

In one study, researchers found that eating later in the day made people hungrier during a 24-hour period, as compared with eating the same meals earlier in the day. Late eating also burned calories at a slower rate and led to fat tissue that stored more calories. Combined, the changes may increase the risk for obesity, the study authors found.

In another study, among firefighters as shift workers, researchers found that eating meals within a 10-hour window decreased the size of bad cholesterol particles, which could reduce risk factors for heart disease. The 10-hour eating window also improved blood pressure and blood sugar levels among those with health conditions such as diabetes, high blood pressure, and high cholesterol.

The two new studies confirm findings from previous studies that indicate humans may have an ideal eating window based on the body’s circadian rhythms, which regulate sleep and wake cycles and can affect appetite, metabolism, and blood sugar levels.

In the firefighter study, for instance, the 10-hour window appears to be a “sweet spot” for the body, the authors found. More severe restrictions, as found with many intermittent fasting diets, could be difficult for the body to maintain.

“When we think about 6 or 8 hours, you might see a benefit, but people might not stick to it for a long time,” Satchidananda Panda, PhD, one of the study authors and a professor at the Salk Institute, La Jolla, Calif., told NBC News.

The new studies had small sample sizes, though they offer insight for future research. In the first study, 16 people who were overweight or obese tried two eating plans for 24-hour periods. Some of them began eating an hour after their natural wake-up time, and others waited to begin eating until about 5 hours after waking up. They ate the same meals with the same calories and nutrients.

The researchers measured their hormone levels and found that eating later decreased the levels of leptin, which helps people to feel full. Eating later also doubled the odds that people felt hungry throughout the day. Those in the study who ate later in the day also had more cravings for starchy or salty foods, as well as meat and dairy, which are energy-dense foods.

The research team also found changes in fat tissue, which could lead to a higher chance of building up new fat cells and a lower chance of burning fat. Late eaters burned about 60 fewer calories than early eaters during the day.

“Your body processes calories differently when you eat late in the day. It tips the scale in favor of weight gain and fat gain,” Dr. Peterson said. “From this study, we can get pretty clear recommendations that people shouldn’t skip breakfast.”

The second study followed 137 firefighters in San Diego who ate a Mediterranean diet with fish, vegetables, fruit, and olive oil for 12 weeks. Among those, 70 firefighters ate during a 10-hour window, and the rest ate during a longer window, generally about 13 hours. They logged their meals in an app and wore devices to track blood sugar levels.

In the 10-hour group, most firefighters ate between 8 a.m. or 9 a.m. and 6 p.m. or 7 p.m. The time-restricted eating appeared to be linked with health benefits, such as less harmful cholesterol buildup and reduced heart disease. 

Among firefighters with risk factors for heart disease, such as high blood pressure and high blood sugar, the time-restricted eating decreased their blood pressure and blood sugar levels. 

The restricted window appears to allow the body to break down toxins and get rid of sodium and other things that can drive up blood pressure and blood sugar, the authors wrote.

During periods of fasting, “organs get some rest from digesting food so they can divert their energy toward repairing cells,” Dr. Panda said.

Many countries around the globe are starting to roll out another booster of the COVID-19 vaccine but, with public interest waning and a sense of normalcy firmly installed in our minds, this may prove an ill-fated effort, unless authorities can provide a coherent answer to the question “Is another jab really needed?” (The short answer is a firm “yes,” of course.)

In what we could call the “chronic” phase of the pandemic, most countries have now settled for a certain number of daily cases and a (relatively low) number of complications and deaths. It’s the vaccines that have afforded us this peace of mind, lest we forget. But they are different to other vaccines that we are more familiar with, such as the MMR that we get as kids and then forget about for the rest of our lives. As good as the different COVID-19 vaccines are, they never came with the promise of generating lifelong antibodies. We knew early on that the immunity they provide slowly wanes with time. That doesn’t mean that those who have their vaccination records up to date (which included a booster probably earlier in 2022) are suddenly exposed. Data suggest that although people several months past their last booster would now be more prone to getting reinfected, the protection against severe disease still hangs around 85%. In other words, their chances of ending up in the hospital are low.

Why worry, then, about further boosting the immune system? The same studies show that an additional jab would increase this percentage up to 99%. Is this roughly 10% improvement really worth another worldwide vaccination campaign? Well, this is a numbers game, after all. The current form of the virus is extremely infectious, and the Northern Hemisphere is heading toward the cold months of the year, which we have seen in past years increases COVID-19 contagions, as you would expect from any airborne virus. Thus, it’s easy to expect a new peak in the number of cases, especially considering that we are not going to apply any of the usual restrictions to prevent this. In these conditions, extending the safety net to a further 10% of the population would substantially reduce the total number of victims. It seems like a good investment of resources.

We can be more surgical about it and direct this new vaccination campaign to the population most likely to end up in the hospital. People with concomitant pathologies are at the top of the list, but it’s also an age issue. On the basis of different studies of the most common ages of admission, the cutoff point for the booster varies from country to country, with the lowest being 50 and in other cases hovering around 65 years of age. Given the safety of these vaccines, if we can afford it, the wider we cast the net, the better, but at least we should make every effort to fully vaccinate the higher age brackets.

The final question is which vaccine to give. There are confounding studies about the importance of switching to Omicron-specific jabs, which are finally available. Although this seems like a good idea, since Omicron infections elicit a more effective range of antibodies and new variants seem to better escape our defenses, recent studies suggest that there actually may not be so much difference with the old formula.

The conclusion? Vaccinate the elderly (and some middle-aged too, if possible) and the frail as soon as possible with any version of the booster you have available, if you want to keep hospital pressure to the minimum and save a fair number of complications and deaths over the next months. This regimen of yearly boosters for some may be the scenario for the upcoming years, similar to what we already do for the flu, so we should get used to it.

As good as the different COVID-19 vaccines are, they never came with the promise of generating lifelong antibodies. We knew early on that the immunity they provide slowly wanes with time. That doesn’t mean that those who have their vaccination records up to date (which included a booster probably earlier in 2022) are suddenly exposed. Data suggest that although people several months past their last booster would now be more prone to getting reinfected, the protection against severe disease still hangs around 85%. In other words, their chances of ending up in the hospital are low.

Why worry, then, about further boosting the immune system? The same studies show that an additional jab would increase this percentage up to 99%. Is this roughly 10% improvement really worth another worldwide vaccination campaign? Well, this is a numbers game, after all. The current form of the virus is extremely infectious, and the Northern Hemisphere is heading toward the cold months of the year, which we have seen in past years increases COVID-19 contagions, as you would expect from any airborne virus. Thus, it’s easy to expect a new peak in the number of cases, especially considering that we are not going to apply any of the usual restrictions to prevent this. In these conditions, extending the safety net to a further 10% of the population would substantially reduce the total number of victims. It seems like a good investment of resources.

We can be more surgical about it and direct this new vaccination campaign to the population most likely to end up in the hospital. People with concomitant pathologies are at the top of the list, but it’s also an age issue. On the basis of different studies of the most common ages of admission, the cutoff point for the booster varies from country to country, with the lowest being 50 and in other cases hovering around 65 years of age. Given the safety of these vaccines, if we can afford it, the wider we cast the net, the better, but at least we should make every effort to fully vaccinate the higher age brackets.

The final question is which vaccine to give. There are confounding studies about the importance of switching to Omicron-specific jabs, which are finally available. Although this seems like a good idea, since Omicron infections elicit a more effective range of antibodies and new variants seem to better escape our defenses, recent studies suggest that there actually may not be so much difference with the old formula.

The conclusion? Vaccinate the elderly (and some middle-aged too, if possible) and the frail as soon as possible with any version of the booster you have available, if you want to keep hospital pressure to the minimum and save a fair number of complications and deaths over the next months. This regimen of yearly boosters for some may be the scenario for the upcoming years, similar to what we already do for the flu, so we should get used to it.

Many countries around the globe are starting to roll out another booster of the COVID-19 vaccine but, with public interest waning and a sense of normalcy firmly installed in our minds, this may prove an ill-fated effort, unless authorities can provide a coherent answer to the question “Is another jab really needed?” (The short answer is a firm “yes,” of course.)

In what we could call the “chronic” phase of the pandemic, most countries have now settled for a certain number of daily cases and a (relatively low) number of complications and deaths. It’s the vaccines that have afforded us this peace of mind, lest we forget. But they are different to other vaccines that we are more familiar with, such as the MMR that we get as kids and then forget about for the rest of our lives.

Restriction of dietary salt to alleviate or prevent volume overload in patients with acute decompensated heart failure (ADHF) is common hospital practice, but without a solid evidence base. A trial testing whether taking salt pills might have benefits for patients with ADHF undergoing intensive diuresis, therefore, may seem a bit counterintuitive.

In just such a randomized, placebo-controlled trial, the approach made no difference to weight loss on diuresis, a proxy for volume reduction, or to serum creatinine levels in ADHF patients receiving high-dose intravenous diuretic therapy.

The patients consumed the extra salt during their intravenous therapy in the form of tablets providing 6 g sodium chloride daily on top of their hospital-provided, low-sodium meals.

During that time, serum sodium levels remained stable for the 34 patients assigned to the salt tablets but dropped significantly in the 31 given placebo pills.

They lost about the same weight, averages of 4 kg and 4.6 kg (8.8-10 lb), respectively, and their urine output was also similar. Patients who took the salt tablets showed less of an increase in blood urea nitrogen (BUN) at both 96 hours and at discharge.

The findings “challenge the routine practice of sodium chloride restriction in acute heart failure, something done thousands of times a day, millions of times a year,” Robert A. Montgomery, MD, Cleveland Clinic, said when presenting the study at the annual scientific meeting of the Heart Failure Society of America.

The trial, called OSPREY-AHF (Oral Sodium to Preserve Renal Efficiency in Acute Heart Failure), also may encourage a shift in ADHF management from a preoccupation with salt restriction to focus more on fighting fluid retention.

OSPREY-HF took on “an established practice that doesn’t have much high-quality evidentiary support,” one guided primarily by consensus and observational data, Montgomery said in an interview.

There are also potential downsides to dietary sodium restriction, including some that may complicate or block ADHF therapies.

“Low-sodium diets can be associated with decreased caloric intake and nutritional quality,” Dr. Montgomery observed. And observational studies suggest that “patients who are on a low sodium diet can develop increased neurohormonal activation. The kidney is not sensing salt, and so starts ramping up the hormones,” which promotes diuretic resistance.

But emerging evidence also suggests “that giving sodium chloride in the form of hypertonic saline can help patients who are diuretic resistant.” The intervention, which appears to attenuate the neurohormonal activation associated with high-dose intravenous diuretics, Dr. Montgomery noted, helped inspire the design of OSPREY-AHF.

Edema consists of “a gallon of water and a pinch of salt, so we really should stop being so salt-centric and think much more about water as the problem in decompensated heart failure,” said John G.F. Cleland, MD, PhD, during the question-and-answer period after Montgomery’s presentation. Dr. Cleland, of the University of Glasgow Institute of Health and Wellbeing, is not connected to OSPREY-AHF.

“I think that maybe we overinterpret how important salt is” as a focus of volume management in ADHF, offered David Lanfear, MD, Henry Ford Health System, Detroit, who is also not part of the study.

OSPREY-AHF was well conducted but applies to a “very specific” clinical setting, Dr. Lanfear said in an interview. “These people are getting aggressive diuresis, a big dose and continuous infusion. It’s not everybody that has heart failure.”

Although the study was small, “I think it will fuel interest in this area and, probably, further investigation,” he said. The trial on its own won’t change practice, “but it will raise some eyebrows.”

The trial included patients with ADHF who have been “admitted to a cardiovascular medicine floor, not the intensive care unit” and were receiving at least 10 mg per hour of furosemide. It excluded any who were “hypernatremic or severely hyponatremic,” said Dr. Montgomery when presenting the study. They were required to have an initial estimated glomerular filtration rate (eGFR) of at least 15 mL/min per 1.73 m².

The patients were randomly assigned double blind at a single center to receive tablets providing 2 g sodium chloride or placebo pills – 34 and 31 patients, respectively – three times daily during intravenous diuresis.

At 96 hours, the two groups showed no difference in change in creatinine levels or change in weight, both primary endpoints. Nor did they differ in urine output or change in eGFR. But serum sodium levels fell further, and BUN levels went up more in those given placebo.

The two groups showed no differences in hospital length of stay, use of renal replacement therapy at 90 days, ICU time during the index hospitalization, 30-day readmission, or 90-day mortality – although the trial wasn’t powered for clinical outcomes, Dr. Montgomery reported.

"We have patients who complain about their sodium-restricted diet, we have patients that have cachexia, who have a lot of complaints about provider-ordered meals and recommendations,” Dr. Montgomery explained in an interview.

Clinicians provide education and invest a lot of effort into getting patients with heart failure to start and maintain a low-sodium diet, he said. “But a low-sodium diet, in prior studies – and our study adds to this – is not a lever that actually seems to positively or adversely affect patients.”

Dr. Montgomery pointed to the recently published SODIUM-HF trial comparing low-sodium and unrestricted-sodium diets in outpatients with heart failure. It saw no clinical benefit from the low-sodium intervention.

Until studies show, potentially, that sodium restriction in hospitalized patients with heart failure makes a clinical difference, Dr. Montgomery said, “I’d say we should invest our time in things that we know are the most helpful, like getting them on guideline-directed medical therapy, when instead we spend an enormous amount of time counseling on and enforcing dietary restriction.”

Support for this study was provided by Cleveland Clinic Heart Vascular and Thoracic Institute’s Wilson Grant and Kaufman Center for Heart Failure Treatment and Recovery Grant. Dr. Lanfear disclosed research support from SomaLogic and Lilly; consulting for Abbott Laboratories, AstraZeneca, Janssen, Martin Pharmaceuticals, and Amgen; and serving on advisory panels for Illumina and Cytokinetics. Dr. Montgomery and Dr. Cleland disclosed no relevant financial relationships.

To be cost effective, compared with metformin, for initial therapy for type 2 diabetes, prices for a sodium-glucose cotransporter-2 (SGLT2) inhibitor or a glucagon-like peptide-1 (GLP-1) agonist would have to fall by at least 70% and at least 90%, respectively, according to estimates.

Thinkstock Photos

The study, modeled on U.S. patients, by Jin G. Choi, MD, and colleagues, was published online Oct. 3 in the Annals of Internal Medicine.

The researchers simulated the lifetime incidence, prevalence, mortality, and costs associated with three different first-line treatment strategies – metformin, an SGLT2 inhibitor, or a GLP-1 agonist – in U.S. patients with untreated type 2 diabetes.

Compared with patients who received initial treatment with metformin, those who received one of the newer drugs had 4.4% to 5.2% lower lifetime rates of congestive heart failure, ischemic heart disease, myocardial infarction, and stroke.

However, to be cost-effective at under $150,000 per quality-adjusted life-years (QALY), SGLT2 inhibitors would need to cost less than $5 a day ($1,800 a year), and GLP-1 agonists would have to cost less than $6 a day ($2,100 a year), a lot less than now.

Knowing how expensive these drugs are, “I am not surprised” that the model predicts that the price would have to drop so much to make them cost-effective, compared with first-line treatment with metformin, senior author Neda Laiteerapong, MD, said in an interview.

“But I am disappointed,” she said, because these drugs are very effective, and if the prices were lower, more people could benefit.

“In the interest of improving access to high-quality care in the United States, our study results indicate the need to reduce SGLT2 inhibitor and GLP-1 receptor agonist medication costs substantially for patients with type 2 [diabetes] to improve health outcomes and prevent exacerbating diabetes health disparities,” the researchers conclude.

One way that the newer drugs might be more widely affordable is if the government became involved, possibly by passing a law similar to the Affordable Insulin Now Act, speculated Dr. Laiteerapong, who is associate director at the Center for Chronic Disease Research and Policy, University of Chicago.
 

‘Current prices too high to encourage first-line adoption’

Guidelines recommend the use of SGLT2 inhibitors and GLP-1 agonists as second-line therapies for patients with type 2 diabetes, but it has not been clear if clinical benefits would outweigh costs for use as first-line therapies.

“Although clinical trials have demonstrated the clinical effectiveness of these newer drugs, they are hundreds of times more expensive than other ... diabetes drugs,” the researchers note.

On the other hand, costs may fall in the coming years when these new drugs come off-patent.

The current study was designed to help inform future clinical guidelines.

The researchers created a population simulation model based on the United Kingdom Prospective Diabetes Study, Outcomes Model version 2 (UKPDS OM2) for diabetes-related complications and mortality, with added information about hypoglycemic events, quality of life, and U.S. costs. 

The researchers also identified a nationally representative sample of people who would be eligible to start first-line diabetes therapy when their A1c reached 7% for the model. 

Using National Health and Nutrition Examination Survey (NHANES) data (2013-2016), the researchers identified about 7.3 million U.S. adults aged 18 and older with self-reported diabetes or an A1c greater than 6.5% with no reported use of diabetes medications.

Patients were an average age of 55, and 55% were women. They had had diabetes for an average of 4.2 years, and 36% had a history of diabetes complications.

The model projected that patients would have an improved life expectancy of 3.0 and 3.4 months from first-line SGLT2 inhibitors and GLP-1 agonists, respectively, compared with initial therapy with metformin due to reduced rates of macrovascular disease.  

“However, the current drug costs would be too high to encourage their adoption as first-line for usual clinical practice,” the researchers report.
 

‘Disparities could remain for decades’

Generic SGLT2 inhibitors could enter the marketplace shortly, because one of two dapagliflozin patents expired in October 2020 and approval for generic alternatives has been sought from the U.S. Food and Drug Administration, Dr. Choi and colleagues note.

However, it could still take decades for medication prices to drop low enough to become affordable, the group cautions. For example, a generic GLP-1 agonist became available in 2017, but costs remain high.

“Without external incentives,” the group writes, “limited access to these drug classes will likely persist (for example, due to higher copays or requirements for prior authorizations), as will further diabetes disparities – for decades into the future – because of differential access to care due to insurance (for example, private vs. public), which often tracks race and ethnicity.”

The study was supported by the American Diabetes Association. Dr. Choi was supported by a National Institutes of Health, National Institute on Aging grant. Dr. Laiteerapong and other co-authors are members of the National Institute of Diabetes and Digestive and Kidney Diseases Chicago Center for Diabetes Translation Research at the University of Chicago. Dr. Choi and Dr. Laiteerapong have reported no relevant financial relationships.

“However, the current drug costs would be too high to encourage their adoption as first-line for usual clinical practice,” the researchers report.
 

‘Disparities could remain for decades’

Generic SGLT2 inhibitors could enter the marketplace shortly, because one of two dapagliflozin patents expired in October 2020 and approval for generic alternatives has been sought from the U.S. Food and Drug Administration, Dr. Choi and colleagues note.

However, it could still take decades for medication prices to drop low enough to become affordable, the group cautions. For example, a generic GLP-1 agonist became available in 2017, but costs remain high.

“Without external incentives,” the group writes, “limited access to these drug classes will likely persist (for example, due to higher copays or requirements for prior authorizations), as will further diabetes disparities – for decades into the future – because of differential access to care due to insurance (for example, private vs. public), which often tracks race and ethnicity.”

The study was supported by the American Diabetes Association. Dr. Choi was supported by a National Institutes of Health, National Institute on Aging grant. Dr. Laiteerapong and other co-authors are members of the National Institute of Diabetes and Digestive and Kidney Diseases Chicago Center for Diabetes Translation Research at the University of Chicago. Dr. Choi and Dr. Laiteerapong have reported no relevant financial relationships.

To be cost effective, compared with metformin, for initial therapy for type 2 diabetes, prices for a sodium-glucose cotransporter-2 (SGLT2) inhibitor or a glucagon-like peptide-1 (GLP-1) agonist would have to fall by at least 70% and at least 90%, respectively, according to estimates.

The study, modeled on U.S. patients, by Jin G. Choi, MD, and colleagues, was published online Oct. 3 in the Annals of Internal Medicine.

The researchers simulated the lifetime incidence, prevalence, mortality, and costs associated with three different first-line treatment strategies – metformin, an SGLT2 inhibitor, or a GLP-1 agonist – in U.S. patients with untreated type 2 diabetes.

Compared with patients who received initial treatment with metformin, those who received one of the newer drugs had 4.4% to 5.2% lower lifetime rates of congestive heart failure, ischemic heart disease, myocardial infarction, and stroke.

However, to be cost-effective at under $150,000 per quality-adjusted life-years (QALY), SGLT2 inhibitors would need to cost less than $5 a day ($1,800 a year), and GLP-1 agonists would have to cost less than $6 a day ($2,100 a year), a lot less than now.

Knowing how expensive these drugs are, “I am not surprised” that the model predicts that the price would have to drop so much to make them cost-effective, compared with first-line treatment with metformin, senior author Neda Laiteerapong, MD, said in an interview.

“But I am disappointed,” she said, because these drugs are very effective, and if the prices were lower, more people could benefit.

“In the interest of improving access to high-quality care in the United States, our study results indicate the need to reduce SGLT2 inhibitor and GLP-1 receptor agonist medication costs substantially for patients with type 2 [diabetes] to improve health outcomes and prevent exacerbating diabetes health disparities,” the researchers conclude.

One way that the newer drugs might be more widely affordable is if the government became involved, possibly by passing a law similar to the Affordable Insulin Now Act, speculated Dr. Laiteerapong, who is associate director at the Center for Chronic Disease Research and Policy, University of Chicago.
 

‘Current prices too high to encourage first-line adoption’

Guidelines recommend the use of SGLT2 inhibitors and GLP-1 agonists as second-line therapies for patients with type 2 diabetes, but it has not been clear if clinical benefits would outweigh costs for use as first-line therapies.

“Although clinical trials have demonstrated the clinical effectiveness of these newer drugs, they are hundreds of times more expensive than other ... diabetes drugs,” the researchers note.

On the other hand, costs may fall in the coming years when these new drugs come off-patent.

The current study was designed to help inform future clinical guidelines.

The researchers created a population simulation model based on the United Kingdom Prospective Diabetes Study, Outcomes Model version 2 (UKPDS OM2) for diabetes-related complications and mortality, with added information about hypoglycemic events, quality of life, and U.S. costs. 

The researchers also identified a nationally representative sample of people who would be eligible to start first-line diabetes therapy when their A1c reached 7% for the model. 

Using National Health and Nutrition Examination Survey (NHANES) data (2013-2016), the researchers identified about 7.3 million U.S. adults aged 18 and older with self-reported diabetes or an A1c greater than 6.5% with no reported use of diabetes medications.

Patients were an average age of 55, and 55% were women. They had had diabetes for an average of 4.2 years, and 36% had a history of diabetes complications.

The model projected that patients would have an improved life expectancy of 3.0 and 3.4 months from first-line SGLT2 inhibitors and GLP-1 agonists, respectively, compared with initial therapy with metformin due to reduced rates of macrovascular disease.  

“However, the current drug costs would be too high to encourage their adoption as first-line for usual clinical practice,” the researchers report.

Don’t like needles? Have we got a vaccine for you

Here’s a quick question: How do you turn the most annoying thing ever into something positive?

No, we’re not talking about politicians this time. No, not Elon Musk, either. Infomercials? Guess again. Humidity? Nope, even more annoying than that.

Give up? The most annoying thing ever is mosquitoes. This time, however, NPR reports that mosquitoes have been used to deliver a vaccine for the very disease they’ve been transmitting to their human food sources all these years.

In a recent proof-of-concept trial, investigators used CRISPR technology to genetically modify malaria-causing Plasmodium falciparum sporozoites, which just happen to live in the salivary glands of Anopheles mosquitoes. And since the Plasmodium parasites are already in the mosquitoes, it made sense to use the buzzy little critters as the delivery device for the vaccine.

More sense than a syringe, you ask? Have you ever tried to poke a syringe into the salivary gland of a mosquito? No, we thought not. Well, we can tell you from experience that it’s really, really hard. Never mind how we know. We just do.

The 14 study volunteers – who were paid $4,100 for their participation – were first exposed to hundreds of mosquitoes carrying the altered Plasmodium parasites. Then, to test the vaccine, they were exposed to mosquitoes that had actual, malaria-carrying Plasmodium. Half of the subjects got malaria, so the vaccine was only 50% effective, meaning there’s still work to do.

Meanwhile, the scientists here at LOTMEco are all over this mosquito-delivery business, working on a vaccine to prevent Elon Musk. Plan B involves some sort of really big swatter.
 

Climate change: Sleeping your life away

It’s no secret that climate change is raising the temperature on everything. You may think you’re getting relief when the sun goes down, but in some places it’s still hot. A new survey conducted in central Japan shows how bad it can be and how higher nighttime temperatures can have a serious impact on people’s health.

Public Domain Vectors

That online survey, the Sleep Quality Index for Daily Sleep, enabled the investigators to correlate sleep quality with daily temperature for 1,284 adults in 2011 and 2012 who completed the survey over 10 days.

Not only was there a significant difference in sleep disturbance among younger men (higher) versus older men, but the prevalence of sleep disturbance went up when the daytime temperature was above 24.8° C. They also found that disability-adjusted life-years (DALYs), which measure time lost through premature death and time lived in certain conditions that put one’s health at risk, were 81.8 years for the city of Nagoya (population, 2.2 million) in 2012.

The damage to health from sleep disorders caused by daily temperatures higher than 25° C “is comparable to that of heatstroke and must be addressed,” lead author Tomohiko Ihara of the University of Tokyo said in a written statement.

The researchers hope that this information will help sway legislators to consider the impact of higher nighttime temperatures and that it can be used to provide guidance for better sleep. The solution for now? Sleep with the air conditioner on. Your energy bill might increase, but just think about those DALYs. If using the AC lowers DALYs and increases time lived, then we say it’s worth it.
 

Maybe it would have been a dragon WITH cancer

If you ask a random person on the street to tell you all they know about the country of Wales, they’ll probably mention two things: One, the contorted collection of jumbled-up letters that is the Welsh language (looking at you, Llanfairpwllgwyngyll­gogery­chwyrn­drobwll­llan­tysilio­gogo­goch) and, two, the association with dragons. The Welsh flag even has a dragon on it.

evakocsan/Pixnio

With that in mind, take a guess as to what sort of statue art dealer Simon Wingett wanted to build in the Welsh town of Wrexham. No, not a monument to the second-longest place name in the world. Try again. His dragon would not be some piddly little thing either; he wanted a virtual kaiju overlooking the town, with the whole statue to stand about 60 meters high. That’s taller than the original 1954 Godzilla.

Artistic masterpieces may sell for frankly insane prices, but art dealers themselves are not the wealthiest of individuals, so Mr. Wingett needed money to fund his dragon-based dream. Lucky for him, he also happened to be the manager of a cancer charity – initially set up by Mr. Wingett’s father, who had throat cancer – which nominally aimed to provide equipment and resources to cancer patients in the Wrexham area.

Yes, this is going precisely where you think it’s going. From 2011 to 2018, when the charity closed, Mr. Wingett used the charity’s donations to fund his dragon statue – which never actually got built, by the way – to the tune of over 400,000 pounds. Of course, Mr. Wingett came under scrutiny when people started to notice that his cancer charity hadn’t actually done anything charitable since 2011, and he was recently banned by the Welsh High Court from serving as trustee of any charity for 10 years. Oh no, tragedy and horror! Truly a punishment worse than death itself.

Okay fine, he also has to pay back 117,000 pounds to actual legitimate cancer charities. The astute mathematicians out there may notice that 117,000 is a lot less than 400,000. But it’s just as the old saying goes: One-quarter of crime doesn’t pay. You can keep three-quarters of it, though, that’s completely fine.

A growing number of Americans with cardiovascular disease (CVD) have limited or uncertain access to food, results of a new study suggest.

An analysis of data from the National Health and Nutrition Examination Survey (NHANES) representing more than 300 million American adults found that, overall, 38.1% of people with cardiovascular disease were food insecure in 2017-2019.

Uphill battle

Johanna Contreras, MD, advanced heart failure and transplant cardiologist at the Mount Sinai Hospital, New York, treats food insecure cardiovascular patients in her practice and tries to educate them about good nutrition. But it is an uphill battle.

“A lot of my patients live in the South Bronx. They have hypertension, hypercholesterolemia, and there are no grocery stores where they can buy fresh vegetables. I talk to them about eating healthy. They tell me it’s impossible. The stores only have pre-packaged foods. So even in the South Bronx, even though it is in New York, it is very hard to get fresh food. And when it is available, it is very expensive,” Dr. Contreras told this news organization.

“Fresh pineapples can cost $8. A fast-food burger costs $3. So that is what they buy: It’s what they can afford. Even the store managers don’t want to stock fresh produce because it can spoil. They open stores, like Whole Foods, but in the more affluent neighborhoods. They should open one in poor neighborhoods,” she said.

Dr. Contreras says she spends much of her time educating her patients about good nutrition. She asks them to keep a food diary and analyzes the results at each visit.

“I look at what they eat, and I try to see how I can use this information in a good way. I advise them to use frozen foods, and avoid canned, because it is a lot healthier. I am pragmatic, because I know that if I tell my patients to eat salmon, for example, they aren’t going to be able to afford it, if they can even access it.”

She also informs them about relatively healthy fast-food choices.

“I tell them to order 100% fruit juice, water, or milk when they go to McDonalds or other fast-food places. So I think this study is very important. Food insecurity is a very important component of cardiovascular disease, and unfortunately, minority communities are where this occurs.”

Dr. Brandt and Dr. Contreras report no relevant financial relationships.

Several leading medical groups on Oct. 3 called on U.S. Attorney General Merrick Garland to investigate and prosecute those responsible for a recent spate of threats and attacks against hospitals and physicians who are providing gender-affirming care.

In an Oct. 3 letter, the American Academy of Pediatrics (AAP), the American Medical Association (AMA), and the Children’s Hospital Association detailed the risk posed by these threats to physicians, patients, and the federally protected right to health care.

The letter comes during a campaign of intimidation and misinformation that has disrupted gender-related care in Seattle, Akron, Ohio, Nashville, Tenn., and Boston in the past few weeks. Hospitals across the country and their ambulatory sites have been forced to substantially increase protection, and “some providers have needed 24/7 security,” according to the letter.

Not only do the threats bully physicians providing gender-affirming care and the patients who receive that care, but “they have also disrupted many other services to families seeking care,” the letter claims.

According to STAT, many hospitals that provide gender-affirming care have responded to the threats by removing information about the treatment from their websites.

At one hospital, a new mother was separated from her preterm infant because the facility’s neonatal intensive care unit was locked down as the result of a bomb threat. (It’s not clear whether that incident is the same as a similar threat that led to the arrest of a 37-year-old Massachusetts woman, who is facing criminal charges in the episode.)

“The attacks are rooted in an intentional campaign of disinformation” by high-profile social media users, according to the letter. The medical organizations have also called on major tech companies, including TikTok, Twitter, and Meta, to do more to prevent the coordination of disinformation campaigns and violence against health care providers and patients.

“We now urge your office to take swift action to investigate and prosecute all organizations, individuals, and entities responsible,” the letter states.

“We cannot stand by as threats of violence against our members and their patients proliferate with little consequence. We call on the Department of Justice to investigate these attacks and social media platforms to reduce the spread of the misinformation enabling them,” AAP President Moira Szilagyi, MD, PhD, FAAP, said in a press release.

In addition to physical threats at their workplace, providers face threats on their personal social media accounts and harassment via phone and email. The letter notes that these unchecked attacks are coming after health care workers spent 3 years working on the front lines of a pandemic.

“Individuals in all workplaces have the right to a safe environment, out of harm’s way and free of intimidation or reprisal,” AMA President Jack Resneck Jr, MD, said in a statement. “The AMA will continue to work with federal, state, and local law enforcement officials to develop and implement strategies that protect hard-working, law-abiding physicians and other health care workers from senseless acts of violence, abuse, and intimidation.”

Several leading medical groups on Oct. 3 called on U.S. Attorney General Merrick Garland to investigate and prosecute those responsible for a recent spate of threats and attacks against hospitals and physicians who are providing gender-affirming care.

In an Oct. 3 letter, the American Academy of Pediatrics (AAP), the American Medical Association (AMA), and the Children’s Hospital Association detailed the risk posed by these threats to physicians, patients, and the federally protected right to health care.

The letter comes during a campaign of intimidation and misinformation that has disrupted gender-related care in Seattle, Akron, Ohio, Nashville, Tenn., and Boston in the past few weeks. Hospitals across the country and their ambulatory sites have been forced to substantially increase protection, and “some providers have needed 24/7 security,” according to the letter.

Not only do the threats bully physicians providing gender-affirming care and the patients who receive that care, but “they have also disrupted many other services to families seeking care,” the letter claims.

According to STAT, many hospitals that provide gender-affirming care have responded to the threats by removing information about the treatment from their websites.

At one hospital, a new mother was separated from her preterm infant because the facility’s neonatal intensive care unit was locked down as the result of a bomb threat. (It’s not clear whether that incident is the same as a similar threat that led to the arrest of a 37-year-old Massachusetts woman, who is facing criminal charges in the episode.)

“The attacks are rooted in an intentional campaign of disinformation” by high-profile social media users, according to the letter. The medical organizations have also called on major tech companies, including TikTok, Twitter, and Meta, to do more to prevent the coordination of disinformation campaigns and violence against health care providers and patients.

“We now urge your office to take swift action to investigate and prosecute all organizations, individuals, and entities responsible,” the letter states.

“We cannot stand by as threats of violence against our members and their patients proliferate with little consequence. We call on the Department of Justice to investigate these attacks and social media platforms to reduce the spread of the misinformation enabling them,” AAP President Moira Szilagyi, MD, PhD, FAAP, said in a press release.

In addition to physical threats at their workplace, providers face threats on their personal social media accounts and harassment via phone and email. The letter notes that these unchecked attacks are coming after health care workers spent 3 years working on the front lines of a pandemic.
