Incorporating gender-nonconforming patients into practice can seem like a daunting task at first. However, obstetricians/gynecologists, midwives, and other advanced women’s health care practitioners can provide quality care for both transgender men and women. Basic preventative services such as routine health and cancer screening and testing for sexually transmitted infections does not require specialized training in transgender health. In fact, administration of hormonal therapy and some surgical interventions are well within the scope of practice of the general obstetrician/gynecologist, as long as the provider has undergone appropriate training to achieve expertise. For example, organizations such as the World Professional Association for Transgender Health (WPATH) not only provides standards of care regarding the treatment of transgender individuals, but they also have training and educational opportunities targeted at providers who wish to become certified in more advanced care of the transgender patient. If an obstetrician/gynecologist is interested in prescribing hormone therapy, seeking further training within the field is a must.

It is important to remember that the process by which transgender individuals express their gender is a spectrum. Not all patients who identify as transgender will seek hormone therapy or surgical procedures. However, even if a provider has not undergone more specific training to administer hormone therapy, it is still very important to have a basic understanding of the hormones, routes of administration, and side effects.

While cross-sex hormone therapy does differ in practice, compared with hormone replacement therapy in cisgender counterparts, the principles are relatively similar. Testosterone therapy is the mainstay treatment for transgender men who desire medical transition.^1,2 The overall goal of therapy is to achieve testosterone levels within the cisgender male physiologic range (300-1000 ng/dL). While the most common route of administration is subcutaneous or intramuscular injections in weekly, biweekly, or quarterly intervals, other routes may include daily transdermal patches and gels or oral formulations.1 Within the first few months of use, patients will notice signs of masculinization such as increased facial and body hair, increased muscle mass, increased libido, and amenorrhea. Other changes include male-pattern hair loss, clitoromegaly, redistribution of fat, voice deepening, and mood changes.¹

Hormone therapy for transgender women is a bit more complicated as estrogen alone will often not achieve feminizing characteristics that are satisfying for patients.³ Estrogen therapy can include oral formulations of 17-beta estradiol or conjugated estrogens, although the latter is typically avoided because of the marked increase in thromboembolic events. Estrogens can also be administered in sublingual, intramuscular, or transdermal forms. Antiandrogens are often required to help decrease endogenous testosterone levels to cisgender female levels (30-100 ng/dL).³ Spironolactone is most commonly prescribed as an adjunct to estrogen therapy. Finasteride and GnRH agonists like leuprolide acetate can also be added if spironolactone is not effective or not tolerated by the patient. Feminizing effects of estrogen can take several months and most commonly include decreased spontaneous erections, decreased libido, breast growth, redistribution of fat to the waist and hips, decreased skin oiliness, and softening of the skin.³

Overall, hormone therapy for both transgender men and women is considered effective, safe, and well tolerated.⁴ Monitoring is typically performed every 3 months within the first year after initiating hormone therapy, and then continued every 6-12 months thereafter. Routine screening for all organs and tissues present (e.g. prostate, breast) should be undertaken.³ While this simply highlights the therapy and surveillance for patients, it is important to remember that many transgender men and women will see an obstetrician/gynecologist at some interval during their transition. Ultimately, it is paramount that we as obstetricians/gynecologists have a basic understanding of the treatments available so we can provide our patients with competent and compassionate care.

In reproductive medicine, there are few, if any, more pressing concerns from our patients than the biological clock, i.e., ovarian aging. While addressing this issue with women can be challenging, particularly for those who are anxious regarding their advanced maternal age, gynecologists must possess a thorough understanding of available diagnostic testing. This article will review the various methods to assess ovarian age and appropriate clinical management.

Ovarian reserve tests

Ovarian reserve represents the quality and quantity of oocytes. The former is defined by the woman’s chronologic age, which is the greatest predictor of fertility. From a peak monthly fecundity rate at age 30 of approximately 20%, the slow and steady decline of fertility ensues. Quantity represents the number of oocytes remaining from the original cohort.

Ovarian reserve is most provocatively gauged by the follicle response to gonadotropin stimulation, typically during an in vitro fertilization (IVF) cycle.

Several biomarkers have been used to assess ovarian age. These include FSH, estradiol, and inhibin B. In general, these tests are more specific than sensitive, i.e., “normal” results do not necessarily exclude decreased ovarian reserve. But as a screening tool for decreased ovarian reserve, the most important factor is the positive predictive value (PPV). Statistically, in a population of women at low risk for decreased ovarian reserve, the PPV will be low despite sensitivity and specificity.

While inhibin B is a more direct and earlier reflection of ovarian function produced by granulose cells, assays lacked consistent results and a standardized cut-off value. FSH is the last biomarker to be affected by decreased ovarian reserve so elevations reflect more “end-stage” ovarian aging.

Additional tests for decreased ovarian reserve include antral follicle count (AFC) and the clomiphene citrate challenge test (CCCT). AFC is determined by using transvaginal ultrasound to count the number of follicular cysts in the 2- to 9-mm range. While AFC can be performed on any day of the cycle, the ovary is most optimally measured on menses because of less cystic activity. A combined AFC of 3-6 is considered severe decreased ovarian reserve. The CCCT involves prescribing clomiphene citrate 100 mg daily from cycle day 5-9 to measure FSH on cycle days 3 and 10. An FSH level greater than 10 IU/L or any elevation in FSH following CCCT is considered decreased ovarian reserve.

FSH had been the standard but levels may dramatically change monthly, making testing only valuable if it is elevated. Consequently, antimüllerian hormone (AMH) and AFC are considered the most useful tools to determine decreased ovarian reserve because of less variability. The other distinct advantage is the ability to obtain AMH any day in the menstrual cycle. Recently, in women undergoing IVF, AMH was superior to FSH in predicting live birth, particularly when their values were discordant (J Ovarian Res. 2018;11:60). While there is no established consensus, the ideal interval for repeating AMH appears to be approximately 3 months (Obstet Gynecol 2016;127:65S-6S).
 

AMH

AMH is expressed in the embryo at 8 weeks by the Sertoli cells of the testis causing the female reproductive internal system (müllerian) to regress. Without AMH expression, the müllerian system remains and the male (woffian duct system) regresses. The discovery of AMH production by the granulosa cells of the ovary launched a new era in the evaluation and management of infertile women. First reported in Fertility & Sterility in 2002 as a much earlier potential marker of ovarian aging, low levels of AMH predict a lower number of eggs in IVF.

AMH levels are produced in the embryo at 36 weeks’ gestation and increase up to the age of 24.5 years, decreasing thereafter. AMH reflects primordial (early) follicles that are FSH independent. The median AMH level decreases per year according to age groups are: 0.25 ng/mL in ages 26-30; 0.2 ng/mL in ages 31-36 years; and 0.1 ng/mL above age 36. (PLOS ONE 2015 doi: 10.1371/journal.pone.0125216).

AMH has also been studied as a potential biomarker to diagnose PCOS. While many women with PCOS have elevated AMH levels (typically greater than 3 ng/mL), there is no consensus on an AMH value that would be a criterion.

Many women, particularly those electing to defer fertility, express interest in obtaining their AMH level to consider planned oocyte cryopreservation, AKA, social egg freezing. While it is possible the results of AMH screening may compel women to electively freeze their eggs, extensive counseling on the implications and pitfalls of AMH levels is essential. Further, AMH cannot be used to accurately predict menopause.
 

Predicting outcomes

No biomarker is necessarily predictive of pregnancy but more a gauge of gonadotropin dosage to induce multifollicular development. AMH is a great predictor of oocyte yield with IVF (J Assist Reprod Genet. 2009;26[7]:383-9). However, in women older than 35 undergoing IVF, low AMH levels have been shown to reduce pregnancy rates (J Hum Reprod Sci. 2017;10:24–30). During IVF cycle attempts, an ultra-low AMH (≤0.4) resulted in high cancellation rates, reduced the number of oocytes retrieved and embryos developed, and lowered pregnancy rates in women of advanced reproductive age.

Alternatively, a study of 750 women who were not infertile and were actively trying to conceive demonstrated no difference in natural pregnancy rates in women aged 30-44 irrespective of AMH levels (JAMA. 2017;318[14]:1367-76).

A special consideration is for cancer patients who are status postgonadotoxic chemotherapy. Their oocyte attrition can be accelerated and AMH levels can become profoundly low. In those patients, current data suggest there is a modest recovery of postchemotherapy AMH levels up to 1 year. Further, oocyte yield following stimulation may be higher than expected despite a poor AMH level.
 

Conclusion

Ovarian aging is currently best measured by combining chronologic age, AFC, and AMH. There is no current evidence that AMH levels should be used to exclude patients from undergoing IVF or to recommend egg donation. Random screening of AMH levels in a low-risk population for decreased ovarian reserve may result in unnecessary alarm.

Yet another study has linked the consumption of ultraprocessed, or “junk,” foods to bad health outcomes.

In a longitudinal analysis of more than 22,000 men and women from southern Italy, those who consumed the most ultraprocessed food (UPF) had the highest risk for cardiovascular disease (CVD) and all-cause mortality, likely mediated through a diet high in sugar, researchers said.

High consumption of UPF in this Mediterranean cohort was associated with a 58% increased risk for CVD mortality and 52% higher risk of dying from ischemic heart disease (IHD) and cerebrovascular causes, independently of known risk factors for CVD, even among individuals who otherwise adhered to the Mediterranean diet.

The findings “should serve as an incentive for limiting consumption of UPF and encouraging natural or minimally processed foods, as several national nutritional policies recommend,” Marialaura Bonaccio, PhD, department of epidemiology and prevention, IRCCS Neuromed, Pozzilli, Italy, and colleagues wrote. The results were published online Dec. 18 in the American Journal of Clinical Nutrition.

Earlier this year, as reported by this news organization, researchers found mounting evidence that the obesity epidemic and the increase in incidence of related chronic conditions corresponded with an increase in the intake of UPF.

A study that was conducted in a European cohort found that adults whose diet included more UPF and beverages, such as ice cream, soda, and hamburgers, were more likely to develop CVD or die sooner than others who had a more wholesome diet.

As reported previously by this news organization, among adults in France who had a 10% higher intake of UPF and beverages, the rate of CVD, coronary heart disease, and cerebrovascular disease was 11% to 13% higher over a period of about 5 years.

Similarly, university graduates in Spain who consumed more than four servings of UPF and beverages a day were 62% more likely to die of any cause over about a decade than those who consumed less than two servings per day.
 

Where’s the food?

There is very little actual food in UPF. “The NOVA classification provides 4 main classes of food and beverages, the last of which is represented by the ultraprocessed food group. This comprises products (e.g., snacks, drinks, and ready meals, ‘created mostly or entirely from substances extracted from foods or derived from food constituents with little, if any intact food, which often contain flavors, colors, and other additives that imitate or intensify the sensory qualities of foods or culinary preparations made from foods,’ ” Dr. Bonaccio and colleagues wrote.

Such foods are very convenient, tasty, inexpensive, and have a long shelf life. They are highly competitive with foods that are naturally ready to consume and freshly prepared dishes and meals, the authors add.

The researchers conducted a longitudinal analysis on 22,475 men and women (mean age, 55 years; range, 43-67 years) who were recruited from the Moli-sani Study, a population-based cohort of men and women aged 35 years and older in the Molise region of southern Italy, between 2005 and 2010. Participants were followed for 8.2 years.

Food intake was assessed with the Food Frequency Questionnaire; UPF was defined using the NOVA classification according to degree of processing.

UPF intakes were categorized as quartiles of the ratio of UPF to total food consumed.

Overall, study participants reported a median of 10% (interquartile range, 6.6%-14.6%) of dietary intake as UPF and a total of 181.5 g/d of UPF intake.

The foods that contributed most to total UPF consumed were processed meat, which accounted for 19.8% of UPF intake; pizza (16.8%); and cakes and pies (13.4%).

High consumers of UPF, defined as those for whom UPF constituted more than 14.6% of their total diet, were more likely to be women, to be younger, and to have a higher educational level. They also reported fewer risk factors and fewer baseline chronic diseases and health conditions than persons who consumed UPF less frequently.

In addition, high consumption of UPF was associated with lower adherence to the Mediterranean diet; higher intake of fat, sugar, dietary cholesterol, and sodium; and lower intake of fiber.

During a median follow-up of 8.2 years, 1,216 all-cause deaths occurred. Of these, 439 were attributed to CVD, 255 to IHD/cerebrovascular disease, 477 to cancer, and 300 to other causes.
 

The more UPF, the higher the risk for CVD, death

The researchers found a direct linear dose-response relation between a 5% increase in the proportion of UPF in the diet and risk for all-cause and CVD mortality.

Individuals who reported the highest intake of UPF (fourth quartile, 14.6% of total food) as opposed to the lowest (first quartile, UPF <6.6%) experienced increased risks for CVD mortality (hazard ratio, 1.58; 95% CI, 1.23-2.03), death from IHD/cerebrovascular disease (HR, 1.52, 95% CI, 1.10-2.09), and all-cause mortality (HR, 1.26; 95% CI, 1.09-1.46).

High sugar content accounted for 36.3% of the relation of UPF with IHD/cerebrovascular mortality. Other nutritional factors, such as saturated fats, were unlikely to play a role, the researchers wrote.

Biomarkers of renal function accounted for 20.1% of the association of UPF with all-cause mortality and 12.0% for that of UPF with CVD mortality.

Subgroup analyses indicated that the magnitude of the association between UPF and all-cause mortality risk was greater among high-risk individuals, such as those with a history of CVD or diabetes. UPF was also likely to be more strongly associated with CVD mortality among those high-risk groups.

The interesting finding that the association between UPF and CVD mortality was greater among individuals with good adherence to the Mediterranean diet, which is known to have health benefits, could be explained by the fact that people who may benefit from a Mediterranean diet are more susceptible to losing health advantages when they also include “detrimental dietary behavior,” whereas those who consume a poor-quality diet are less likely to be harmed by an additional unhealthy behavior such as eating UPF regularly, wrote Dr. Bonaccio and colleagues.

“This is an interesting study confirming that consumption of highly processed foods such as pizza, processed meats, and soda are associated with greater risks of cardiovascular disease,” Walter Willett, MD, professor of epidemiology and nutrition, Harvard School of Public Health, Boston, said in an interview.

“These higher risks appear to be mediated in part by high intakes of saturated fat and sugar, but lower intakes of health-promoting aspects of diet also likely contribute to the findings,” Dr. Willett said.

“Some processing of food can be useful for preservation and control of infectious agents, but in general, a diet emphasizing minimally processed fruits and vegetables, whole grains, nuts, legumes, and plant sources of fat will be best for long-term well-being,” he said.

The study was supported in part by the Italian Ministry of Health and the HYPERCAN Study Italian Association for Cancer Research. Dr. Bonaccio and Dr. Willett reported no relevant financial relationships.

Yet another study has linked the consumption of ultraprocessed, or “junk,” foods to bad health outcomes.

In a longitudinal analysis of more than 22,000 men and women from southern Italy, those who consumed the most ultraprocessed food (UPF) had the highest risk for cardiovascular disease (CVD) and all-cause mortality, likely mediated through a diet high in sugar, researchers said.

High consumption of UPF in this Mediterranean cohort was associated with a 58% increased risk for CVD mortality and 52% higher risk of dying from ischemic heart disease (IHD) and cerebrovascular causes, independently of known risk factors for CVD, even among individuals who otherwise adhered to the Mediterranean diet.

Researchers in Italy have identified microplastic (MP) fragments in four human placentas that were donated for study after delivery.

“The presence of MPs in the placenta tissue requires the reconsideration of the immunological mechanism of self-tolerance,” wrote Antonio Ragusa, MD, of San Giovanni Calibita Fatebenefratelli Hospital, Rome, and colleagues. “Placenta represents the interface between the fetus and the environment.”

In a pilot observational study published in Environment International, the researchers used Raman microspectroscopy to analyze placentas from six women with physiological pregnancies for the presence of MPs. MPs were defined as particles smaller than 5 mm resulting from the degradation of plastic in the environment, such as plastic objects, coatings, adhesives, paints, and personal care products. Data from previous studies have shown that MPs can move into living organisms, but this study is the first to identify MPs in human placentas, the researchers said.
 

Polypropylene and pigments identified

A total of 12 microplastic fragments were identified in tissue from the placentas of four women; 5 in the fetal side, 4 in the maternal side, and 3 in the chorioamniotic membranes, which suggests that MPs can reach all levels of placental tissue, the researchers said. Most of the MPs were approximately 10 mcm in size, but two were roughly 5 mcm.

All 12 of the MPs were pigmented; of these, 3 were identified as stained polypropylene and the other 9 contained pigments used in a variety of items including coatings, paints, adhesives, plasters, finger paints, polymers and cosmetics, and personal care products. The researchers used a software program to analyze the pigments and matched them with information from the European Chemical Agency for identification of the commercial name, chemical formula, International Union of Pure and Applied Chemistry name, and Color Index Constitution Number.

The mechanism by which MPs may enter the bloodstream and access the placenta remains unclear, the researchers said. “The most probable transport route for MPs is a mechanism of particle uptake and translocation, already described for the internalization from the gastrointestinal tract. Once MPs have reached the maternal surface of the placenta, as other exogenous materials, they can invade the tissue in depth by several transport mechanisms, both active and passive, that are not clearly understood yet.”

The range in location and characteristics of the particles found in the study suggest that passage of MPs into the placenta may be affected by physiological conditions and genetics, as well as food and lifestyle habits of the patients, the researchers said.

The study findings were limited by several factors including the small sample size and observational study design.

However, the presence of MPs in the placenta could affect the pregnancy in various ways, including immunity, growth factor signaling, maternal-fetal communication, and trafficking of various cell types and macrophages, the researchers wrote. In addition, MPs could have a transgenerational effect on metabolism and reproduction.

“Further studies need to be performed to assess if the presence of MPs in human placenta may trigger immune responses or may lead to the release of toxic contaminants, resulting harmful for pregnancy,” they concluded.
 

Cause for concern, but research gaps remain

“Microplastics are ubiquitous in the environment and are detectable in tissues of humans and wildlife,” Andrea C. Gore, PhD, of the University of Texas, Austin, said in an interview. “To my knowledge, this was never previously shown in the placenta.

“There are two reasons why detection of microplastics in placenta would be concerning,” Dr. Gore explained. “First, microplastics may be endocrine-disrupting chemicals (EDCs), or they may concentrate other chemicals that are EDCs. Second, the developing fetus is exquisitely sensitive to natural hormones, and disruptions by EDCs may lead to both immediate as well as latent health problems.

“Clinicians should be concerned about particulate matter in the placenta, “although the number of particles was very small,” said Dr. Gore. “Out of six women, four had particles in their placentas (total of 12) of which one was confirmed to be a plastic (polypropylene). For the other 11 particles, only the pigments could be identified, so more work is needed to confirm whether they were plastics.

“If I were a clinician discussing this article with my patients, I would point out that, although it is concerning that microparticles are present in placenta, few of them were found, and it is not known whether any chemical is released from the particles or actually reaches the fetal circulation,” Dr. Gore said. “I would use it as a starting point for a conversation about lifestyle during pregnancy and encouraging pregnant women to avoid eating foods stored and/or prepared in plastics.”

The limitations of the study include not only the small sample size, but also that “the type of chemicals in the microplastics is for the most part unknown, making it difficult to assess which (if any) might be EDCs,” Dr. Gore emphasized. In addition, “lifestyle and diet can greatly affect exposures to chemicals, so this needs to be carefully factored into the analysis.” Also, “most of the detected particles are pigments, so connections to plastics (other than the one polypropylene particle) need to be strengthened,” she explained.

“The pathways by which microplastics might get into tissues are still rather speculative, and the mechanisms proposed by the authors (endocytosis, paracellular diffusion, entry via airways) need to be demonstrated,” Dr. Gore concluded.

The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Gore had no conflicts to disclose.

“Microplastics are ubiquitous in the environment and are detectable in tissues of humans and wildlife,” Andrea C. Gore, PhD, of the University of Texas, Austin, said in an interview. “To my knowledge, this was never previously shown in the placenta.

“There are two reasons why detection of microplastics in placenta would be concerning,” Dr. Gore explained. “First, microplastics may be endocrine-disrupting chemicals (EDCs), or they may concentrate other chemicals that are EDCs. Second, the developing fetus is exquisitely sensitive to natural hormones, and disruptions by EDCs may lead to both immediate as well as latent health problems.

“Clinicians should be concerned about particulate matter in the placenta, “although the number of particles was very small,” said Dr. Gore. “Out of six women, four had particles in their placentas (total of 12) of which one was confirmed to be a plastic (polypropylene). For the other 11 particles, only the pigments could be identified, so more work is needed to confirm whether they were plastics.

“If I were a clinician discussing this article with my patients, I would point out that, although it is concerning that microparticles are present in placenta, few of them were found, and it is not known whether any chemical is released from the particles or actually reaches the fetal circulation,” Dr. Gore said. “I would use it as a starting point for a conversation about lifestyle during pregnancy and encouraging pregnant women to avoid eating foods stored and/or prepared in plastics.”

The limitations of the study include not only the small sample size, but also that “the type of chemicals in the microplastics is for the most part unknown, making it difficult to assess which (if any) might be EDCs,” Dr. Gore emphasized. In addition, “lifestyle and diet can greatly affect exposures to chemicals, so this needs to be carefully factored into the analysis.” Also, “most of the detected particles are pigments, so connections to plastics (other than the one polypropylene particle) need to be strengthened,” she explained.

“The pathways by which microplastics might get into tissues are still rather speculative, and the mechanisms proposed by the authors (endocytosis, paracellular diffusion, entry via airways) need to be demonstrated,” Dr. Gore concluded.

The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Gore had no conflicts to disclose.

A proposal to delay administration of the second dose of COVID-19 vaccines – suggested as a strategy to boost the number of people who get some degree of protection from a single immunization with the Pfizer/BioNTech or Moderna vaccines – is inciting a strong debate among clinicians and public health officials.

Proponents argue that getting some degree of protection to a greater number of Americans is worthwhile, particularly as case numbers and hospitalizations continue to rise and with the emergence of a more contagious variant.

Opponents raise concerns about diverting from the two-dose schedule evaluated in clinical trials, including a lack of data on long-term protection from a single dose. They also suggest a longer interval between dosing could increase resistance of SARS-CoV-2 virus.

It is time to consider delaying the second dose, Robert M. Wachter, MD, at the University of California San Francisco, and Ashish Jha, MD, MPH, at Brown University in Providence, R.I., wrote in an opinion piece in The Washington Post Jan. 3. 

The two experts state that supply constraints, distribution bottlenecks, and hundreds of thousands of new infections daily prompted them to change their stance on administering COVID-19 vaccines according to the two-dose clinical trial regimen. Furthermore, they cited a study in the New England Journal of Medicine that suggests 80%-90% efficacy for preventing SARS-CoV-2 infection following one dose of the Moderna vaccine. 

Not everyone agrees one dose is a good idea. “Clinical trials with specific schedules for vaccine dosing – that’s the whole basis of the scientific evidence,” Maria Elena Bottazzi, PhD, associate dean of the National School of Tropical Medicine at Baylor College of Medicine in Houston, said in an interview.

After one dose “the immune system is learning, but it’s not ideal. That’s why you need the second dose,” Dr. Bottazzi said. “I appreciate the urgency and the anxiety ... but the data support [that] clinical efficacy requires two doses.”

Another proposed strategy to extend the current supply of COVID-19 vaccines to more Americans involves splitting the current dosage of the Moderna vaccine in half. Officials in the United States and the United Kingdom are reportedly considering this approach. In the United States, the Food and Drug Administration would have to approve any dosing change.
 

Agreeing to disagree

Dr. Wachter shared a link to his opinion piece on Twitter, stating that “We both came to this view because of the slow rollout & the new variant. But it’s a tough call and reasonable people will disagree.”

As predicted, the tweet elicited a number of strong opinions.

“There are no correct answers but there’s data deficiency, plenty of fodder and need for healthy, intellectual debate. That wouldn’t be occurring if there was an ample supply of vaccines,” Eric Topol, MD, director of the Scripps Translational Science Institute and editor-in-chief of Medscape, tweeted on Jan. 3.

“If the problem were with the supply of the vaccine, one might make an argument for focusing on 1st dose. But the problem is in distribution of the vaccine & giving actual doses,” John Grohol, PsyD, tweeted.

“Right now we don’t have a supply issue, we have a distribution issue,” Angela Shen, ScD, MPH, a research scientist in the Vaccine Education Center at Children’s Hospital of Philadelphia, said in an interview. Emergency use authorization for the Johnson & Johnson and other COVID-19 vaccines in development could further boost available supplies, she added.

“The clinical trials studied two doses,” Dr. Shen said. “We don’t have data that one dose is going to have lasting protection.” 
 

Does new variant change equation?

Dr. Wachter and Dr. Jha, in their editorial, cited a quote from former boxing champion Mike Tyson: “Everybody has a plan until they’ve been punched in the mouth.” ‘Punches’ such as the new variant, the high number of cases and deaths in the United States, and other problems prompted them to advocate for the delayed dosing strategy.

“Appreciate the concern for the new variant – I think it’s worth noting that we’re punching ourselves in the mouth with the slow vaccine rollout, which is the first problem to solve,” Jake Quinton, MD, an internist at UCLA Health in Los Angeles, noted on Twitter.

 

Vaccine and public resistance raised

“I agree with the problem but not with the proposed solution, which is guesswork not based on data,” the Jan Grimm Lab at Memorial Sloan Kettering Cancer Center in New York responded to Dr. Wachter and Dr. Jha on Twitter. “There ARE data though that show that 1 shot alone did not elicit sufficient T-cell nor antibody response. This might also lead to mutations resistant to the vaccines. Dangerous!”

Other physicians took to Twitter to point out that changing the recommendations at this point could further erode public confidence in COVID-19 immunization. For example, Deirdre Habermehl, MD, wrote, “We’ve spent months telling the public the best route is to follow the science and now without data think a course correction based on a guesstimate is ok? Public confidence is low enough and the real issue is logistics at this point.”

Dr. Shen and Dr. Bottazzi have disclosed no relevant financial relationships.

The United States started 2021 they way it ended 2020: Setting new records amidst the coronavirus pandemic.

The country passed the 20 million mark for coronavirus cases on Friday, setting the mark sometime around noon, according to Johns Hopkins University’s COVID-19 tracker. The total is nearly twice as many as the next worst country – India, which has 10.28 million cases.

Along with the case count, more than 346,000 Americans have now died of COVID-19, the disease caused by the coronavirus. That is 77% more fatalities than Brazil, which ranks second globally with 194,949 deaths.

More than 125,370 coronavirus patients were hospitalized on Thursday, the fourth record-setting day in a row, according to the COVID Tracking Project.

Going by official tallies, it took 292 days for the United States to reach its first 10 million cases, and just 54 more days to double it, CNN reported.

Meanwhile, 12.41 million doses of COVID-19 vaccines have been distributed in the United States as of Wednesday, according to the Centers for Disease Control and Prevention. Yet only 2.8 million people have received the first of a two-shot regimen.

The slower-than-hoped-for rollout of the Pfizer and Moderna vaccines comes as a new variant of the coronavirus has emerged in a third state. Florida officials announced a confirmed case of the new variant – believed to have originated in the United Kingdom – in Martin County in southeast Florida.

The state health department said on Twitter that the patient is a man in his 20s with no history of travel. The department said it is working with the CDC to investigate.

The variant has also been confirmed in cases in Colorado and California. It is believed to be more contagious. The BBC reported that the new variant increases the reproduction, or “R number,” by 0.4 and 0.7. The UK’s most recent R number has been estimated at 1.1-1.3, meaning anyone who has the coronavirus could be assumed to spread it to up to 1.3 people.

The R number needs to be below 1.0 for the spread of the virus to fall.

“There is a huge difference in how easily the variant virus spreads,” Professor Axel Gandy of London’s Imperial College told BBC News. “This is the most serious change in the virus since the epidemic began.”

Congress has ordered the holdouts among U.S. states to have their Medicaid programs cover expenses related to participation in certain clinical trials, a move that was hailed by the American Society of Clinical Oncology and other groups as a boost to trials as well as to patients with serious illness who have lower incomes.

A massive wrap-up spending/COVID-19 relief bill that was signed into law Dec. 27 carried with it a mandate on Medicaid. States are ordered to put in place Medicaid payment policies for routine items and services, such as the cost of physician visits or laboratory tests, that are provided in connection with participation in clinical trials for serious and life-threatening conditions. The law includes a January 2022 target date for this coverage through Medicaid.

Medicare and other large insurers already pick up the tab for these kinds of expenses, leaving Medicaid as an outlier, ASCO noted in a press statement. ASCO and other cancer groups have for years pressed Medicaid to cover routine expenses for people participating in clinical trials. Already, 15 states, including California, require their Medicaid programs to cover these expenses, according to ASCO.

“We believe that the trials can bring extra benefits to patients,” said Monica M. Bertagnolli, MD, of Dana-Farber Cancer Institute, Boston. Dr. Bertagnolli has worked for years to secure Medicaid coverage for expenses connected to clinical trials.

Although Medicaid covers costs of standard care for cancer patients, people enrolled in the program may have concerns about participating in clinical studies, said Dr. Bertagnolli, chair of the Association for Clinical Oncology, which was established by ASCO to promote wider access to cancer care. Having extra medical expenses may be more than these patients can tolerate.

“Many of them just say, ‘I can’t take that financial risk, so I’ll just stay with standard of care,’ “ Dr. Bertagnolli said in an interview.
 

Equity issues

Medicaid has expanded greatly, owing to financial aid provided to states through the Affordable Care Act of 2010.

To date, 38 of 50 U.S. states have accepted federal aid to lift income limits for Medicaid eligibility, according to a tally kept by the nonprofit Kaiser Family Foundation. This Medicaid expansion has given more of the nation’s working poor access to health.care, including cancer treatment. Between 2013 and January 2020, enrollment in Medicaid in expansion states increased by about 12.4 million, according to the Medicaid and CHIP Payment and Access Commission.

Medicaid is the nation’s dominant health insurer. Enrollment has been around 70 million in recent months.

That tops the 61 million enrolled in Medicare, the federal program for people aged 65 and older and those with disabilities. (There’s some overlap between Medicare and Medicaid. About 12.8 million persons were dually eligible for these programs in 2018.) UnitedHealth, a giant private insurer, has about 43 million domestic customers.

Medicaid also serves many of the groups of people for which researchers have been seeking to increase participation in clinical trials. ASCO’s Association for Clinical Oncology and dozens of its partners raised this point in a letter to congressional leaders on Feb. 15, 2020.

“Lack of participation in clinical trials from the Medicaid population means these patients are being excluded from potentially life-saving trials and are not reflected in the outcome of the clinical research,” the groups wrote. “Increased access to clinical trial participation for Medicaid enrollees helps ensure medical research results more accurately capture and reflect the populations of this country.”

The ACA’s Medicaid expansion is working to address some of the racial gaps in insurance coverage, according to a January 2020 report from the nonprofit Commonwealth Fund.

Black and Hispanic adults are almost twice as likely as are White adults to have incomes that are less than 200% of the federal poverty level, according to the Commonwealth Fund report. The report also said that people in these groups reported significantly higher rates of cost-related problems in receiving care before the Medicaid expansion began in 2014.

The uninsured rate for Black adults dropped from 24.4% in 2013 to 14.4% in 2018; the rate for Hispanic adults fell from 40.2% to 24.9%, according to the Commonwealth Fund report.

There are concerns, though, about attempts by some governors to impose onerous restrictions on adults enrolled in Medicaid, Dr. Bertagnolli said. She was president of ASCO in 2018 when the group called on the Centers for Medicare & Medicaid Services to reject state requests to create restrictions that could hinder people’s access to cancer screening or care.

The Trump administration encouraged governors to adopt work requirements. As a result, a dozen states approved these policies, according to a November report from the nonprofit Center on Budget and Policy Priorities. The efforts were blocked by courts.

Data from the limited period of implementation in Arkansas, Michigan, and New Hampshire provide evidence that these kinds of requirements don’t work as intended, according to the CBPP report.

“In all three states, evidence suggests that people who were working and people with serious health needs who should have been eligible for exemptions lost coverage or were at risk of losing coverage due to red tape,” CBPP analysts Jennifer Wagner and Jessica Schubel wrote in their report.

In 2019, The New England Journal of Medicine published an article about the early stages of the Arkansas experiment with Medicaid work rules. Almost 17,000 adults lost their health care coverage in the initial months of implementation, but there appeared to be no significant difference in employment, Benjamin Sommers, MD, PhD, of the Harvard School of Public Health, Boston, and colleagues wrote in their article.

For many people in Arkansas, coverage was lost because of difficulties in reporting compliance with the Medicaid work rule, not because of the employment mandate itself, according to the authors. More than 95% of persons who were targeted by Arkansas’ Medicaid work policy already met its requirements or should have been exempt, they wrote.

Democrats have tended to oppose efforts to attach work requirements, which can include volunteer activities or career training, to Medicaid. Dr. Bertagnolli said there is a need to guard against any future bid to add work requirements to the program.

Extra bureaucratic hurdles may pose an especially tough burden on working adults enrolled in Medicaid, she said.

People who qualify for the program may already be worried about their finances while juggling continued demands of child care and employment, she said. They don’t need to be put at risk of losing access to medical care over administrative rules while undergoing cancer treatment, she said.

“We have to take care of people who are sick. That’s just the way it is,” Dr. Bertagnolli said.

“Lack of participation in clinical trials from the Medicaid population means these patients are being excluded from potentially life-saving trials and are not reflected in the outcome of the clinical research,” the groups wrote. “Increased access to clinical trial participation for Medicaid enrollees helps ensure medical research results more accurately capture and reflect the populations of this country.”

The ACA’s Medicaid expansion is working to address some of the racial gaps in insurance coverage, according to a January 2020 report from the nonprofit Commonwealth Fund.

Black and Hispanic adults are almost twice as likely as are White adults to have incomes that are less than 200% of the federal poverty level, according to the Commonwealth Fund report. The report also said that people in these groups reported significantly higher rates of cost-related problems in receiving care before the Medicaid expansion began in 2014.

The uninsured rate for Black adults dropped from 24.4% in 2013 to 14.4% in 2018; the rate for Hispanic adults fell from 40.2% to 24.9%, according to the Commonwealth Fund report.

There are concerns, though, about attempts by some governors to impose onerous restrictions on adults enrolled in Medicaid, Dr. Bertagnolli said. She was president of ASCO in 2018 when the group called on the Centers for Medicare & Medicaid Services to reject state requests to create restrictions that could hinder people’s access to cancer screening or care.

The Trump administration encouraged governors to adopt work requirements. As a result, a dozen states approved these policies, according to a November report from the nonprofit Center on Budget and Policy Priorities. The efforts were blocked by courts.

Data from the limited period of implementation in Arkansas, Michigan, and New Hampshire provide evidence that these kinds of requirements don’t work as intended, according to the CBPP report.

“In all three states, evidence suggests that people who were working and people with serious health needs who should have been eligible for exemptions lost coverage or were at risk of losing coverage due to red tape,” CBPP analysts Jennifer Wagner and Jessica Schubel wrote in their report.

In 2019, The New England Journal of Medicine published an article about the early stages of the Arkansas experiment with Medicaid work rules. Almost 17,000 adults lost their health care coverage in the initial months of implementation, but there appeared to be no significant difference in employment, Benjamin Sommers, MD, PhD, of the Harvard School of Public Health, Boston, and colleagues wrote in their article.

For many people in Arkansas, coverage was lost because of difficulties in reporting compliance with the Medicaid work rule, not because of the employment mandate itself, according to the authors. More than 95% of persons who were targeted by Arkansas’ Medicaid work policy already met its requirements or should have been exempt, they wrote.

Democrats have tended to oppose efforts to attach work requirements, which can include volunteer activities or career training, to Medicaid. Dr. Bertagnolli said there is a need to guard against any future bid to add work requirements to the program.

Extra bureaucratic hurdles may pose an especially tough burden on working adults enrolled in Medicaid, she said.

People who qualify for the program may already be worried about their finances while juggling continued demands of child care and employment, she said. They don’t need to be put at risk of losing access to medical care over administrative rules while undergoing cancer treatment, she said.

“We have to take care of people who are sick. That’s just the way it is,” Dr. Bertagnolli said.

Congress has ordered the holdouts among U.S. states to have their Medicaid programs cover expenses related to participation in certain clinical trials, a move that was hailed by the American Society of Clinical Oncology and other groups as a boost to trials as well as to patients with serious illness who have lower incomes.

A massive wrap-up spending/COVID-19 relief bill that was signed into law Dec. 27 carried with it a mandate on Medicaid. States are ordered to put in place Medicaid payment policies for routine items and services, such as the cost of physician visits or laboratory tests, that are provided in connection with participation in clinical trials for serious and life-threatening conditions. The law includes a January 2022 target date for this coverage through Medicaid.

Medicare and other large insurers already pick up the tab for these kinds of expenses, leaving Medicaid as an outlier, ASCO noted in a press statement. ASCO and other cancer groups have for years pressed Medicaid to cover routine expenses for people participating in clinical trials. Already, 15 states, including California, require their Medicaid programs to cover these expenses, according to ASCO.

“We believe that the trials can bring extra benefits to patients,” said Monica M. Bertagnolli, MD, of Dana-Farber Cancer Institute, Boston. Dr. Bertagnolli has worked for years to secure Medicaid coverage for expenses connected to clinical trials.

Although Medicaid covers costs of standard care for cancer patients, people enrolled in the program may have concerns about participating in clinical studies, said Dr. Bertagnolli, chair of the Association for Clinical Oncology, which was established by ASCO to promote wider access to cancer care. Having extra medical expenses may be more than these patients can tolerate.

“Many of them just say, ‘I can’t take that financial risk, so I’ll just stay with standard of care,’ “ Dr. Bertagnolli said in an interview.
 

Equity issues

Medicaid has expanded greatly, owing to financial aid provided to states through the Affordable Care Act of 2010.

To date, 38 of 50 U.S. states have accepted federal aid to lift income limits for Medicaid eligibility, according to a tally kept by the nonprofit Kaiser Family Foundation. This Medicaid expansion has given more of the nation’s working poor access to health.care, including cancer treatment. Between 2013 and January 2020, enrollment in Medicaid in expansion states increased by about 12.4 million, according to the Medicaid and CHIP Payment and Access Commission.

Medicaid is the nation’s dominant health insurer. Enrollment has been around 70 million in recent months.

That tops the 61 million enrolled in Medicare, the federal program for people aged 65 and older and those with disabilities. (There’s some overlap between Medicare and Medicaid. About 12.8 million persons were dually eligible for these programs in 2018.) UnitedHealth, a giant private insurer, has about 43 million domestic customers.

Medicaid also serves many of the groups of people for which researchers have been seeking to increase participation in clinical trials. ASCO’s Association for Clinical Oncology and dozens of its partners raised this point in a letter to congressional leaders on Feb. 15, 2020.

Millions of Americans with treatment-resistant hypertension are likely not being tested to determine whether their high blood pressure is driven by primary aldosteronism (PA), despite guidelines that call for such an approach, according to findings from the first reported large-scale, multicenter study of PA testing practices.

Researchers ran a retrospective review of PA testing among 269,010 patients who met the definition as having treatment-resistant hypertension and were managed at any one of 130 Veterans Health Administration (VHA) medical centers from 2000 to 2017.

The results showed that, despite the fact that primary aldosteronism is highly prevalent among patients with treatment-resistant hypertension, only 4,277 (1.6%) underwent assessment for PA during a median of 3.3 years’ follow-up after they first met the defining criteria, Jordana B. Cohen, MD, and her associates reported in a study published in Annals of Internal Medicine on December 28.

“Testing rates also did not change meaningfully over nearly 2 decades ... despite an increasing number of guidelines recommending testing for primary aldosteronism in this population,” including the most recent recommendations from the Endocrine Society, issued in 2016, noted Dr. Cohen, a nephrologist and hypertension researcher at the University of Pennsylvania in Philadelphia, and colleagues.

Most patients in the study (almost 90%) were seen by a primary care practitioner (PCP).

The small percentage of patients seen by a nephrologist or endocrinologist were more than twice as likely to be tested for PA than those seen by a PCP or cardiologist.

Those clinicians who did order a test for PA were much more likely to treat patients with the appropriate medication, a mineralocorticoid receptor antagonist (MRA). In addition, therapy was started sooner, the researchers found.

“Our results corroborate” earlier reports from smaller health systems and suggest that dramatic underuse of PA assessment “is an issue across the US,” Dr. Cohen said in an interview.

The VHA experience “is very representative of what we think goes on across U.S. practice” and contrasts with the VHA’s reputation for “doing a pretty good job managing hypertension” in general, she noted.
 

Missed diagnosis, missed treatment

Dr. Cohen believes a number of factors likely help drive the abysmally low rate of PA testing they observed in the VHA system. She believes rates of PA testing are low elsewhere as well.

First, optimal hypertension management “is often taken for granted” but is challenging in busy primary care practices, so many of patients likely fall through the cracks, she said.

Dr. Cohen cited efforts at her institution, as well as by the VHA system, to better employ electronic health records to flag patients with treatment-resistant hypertension – defined as patients whose systolic or diastolic blood pressure remains at or above 140/90 mm Hg on at least two successive measurements at least a month apart while the patient is undergoing treatment with three conventional antihypertensive drugs – and to guide clinicians to order the right tests and treatments for these patients.

Many care providers mistakenly “see treatment-resistant hypertension as a disease of noncompliance,” although it is much more often the result of a missed diagnosis and inadequate intervention, she explained.
 

Physicians in denial; side effects of MRAs may deter prescribing

A second big cause of low PA testing rates is that doctors make the mistake of thinking a PA test result won’t change how they manage these patients.

The established treatment for most patients with treatment-resistant hypertension as well as PA is adding an MRA, either spironolactone or eplerenone (Inspra).

Many providers cling to the belief that they will start an MRA in these patients without first determining their PA status, says Dr. Cohen, but the data she and her colleagues collected show the opposite.

Overall, about 13% of all patients in the study began treatment with an MRA during follow-up. The likelihood of starting treatment with this drug class was fourfold higher among the patients tested for PA compared with those who were not tested.

PA testing also hastened the start of MRA use by more than a year, compared with untested patients.

“Providers think they prescribe an MRA” to treatment-resistant patients, “but it’s part of their denial. They are not using the evidence-based treatments [spironolactone or eplerenone], perhaps because of concerns about MRA side effects, although those have been pretty well overcome during the past 20 years,” she observed.

Dr. Cohen says gynecomastia is one adverse effect that gives pause to VHA clinicians who see a heavily male patient population. “It’s probably the biggest concern and why PA testing and MRA use is low” in the VHA system, she said.

“You can use a lower dosage of spironolactone, and the incidence is less common with eplerenone,” although using eplerenone does not completely eliminate all gynecomastia cases, she noted.

At the University of Pennsylvania hospitals, men often start on spironolactone first because it retains a significant price advantage, even though eplerenone is now generic, but “if there is a hint of gynecomastia, we quickly switch to eplerenone, which is usually well tolerated,” she explained.

And while eplerenone has a reputation of being less effective than spironolactone, “I’ve prescribed a lot of eplerenone and have had good results,” Dr. Cohen said. “Even if the blood pressure lowering is not as great compared with spironolactone, it still blunts the toxic effects of aldosterone on target organs.”

Hyperkalemia is the other big concern about spironolactone and eplerenone. Both agents cause it at roughly the same rate, although the rate is lower in patients without chronic kidney disease.

A new, nonsteroidal MRA, finerenone, caused substantially less hyperkalemia in a recent phase 3 trial, FIDELIO-DKD, and as a nonsteroidal MRA, it does not cause gynecomastia. Finerenone has promise as a potentially safer option for treating PA and treatment-resistant hypertension, noted Cohen, but so far, no advanced clinical trials have been launched to examine its efficacy for these indications.
 

PA testing allows a surgical option

A third reason to test patients with treatment-resistant hypertension for PA is that jumping straight to MRA treatment denies the patient assessment for a unilateral adrenal adenoma as the cause of excess aldosterone.

When unilateral adenomas exist, patients are candidates for adrenalectomy. Despite the potential advantage this gives patients to eliminate the cause of their PA without the need for additional drug treatment, some clinicians don’t see this as a compelling rationale to test for PA because they have a bias against surgery or have seen too many cases in which surgery failed to produce full hypertension resolution.

“It’s all about setting expectations appropriately” for the impact of this surgery, Dr. Cohen said.

“Adrenalectomy is not a cure; it just gets rid of the source of excess aldosterone.” But in patients with long-standing PA and hypertension, this is often not enough to completely resolve entrenched cardiovascular pathology.
 

PCPs, cardiologists in rural locations least likely to order PA testing

Of the 269,010 patients analyzed by Dr. Cohen and her coauthors, the average age was 65 years; 96% were men; half were obese; and 40% had diabetes. The researchers excluded patients who had already been tested for PA, as well as those who were already receiving treatment with an MRA.

For 88% of the patients, the main physician overseeing care was a PCP. A cardiologist was the main physician for 10%; a nephrologist, for 1%; and an endocrinologist, for fewer than 1%.

The rate of testing for PA varied across the 130 VHA centers that contributed data, ranging from 0% to 6%. The testing data showed that endocrinologists were most likely to order PA testing, doing it 2.48-fold more often than PCPs. Nephrologists were roughly twice as likely to order PA testing than PCPs, and cardiologists ordered testing at about the same rate as PCPs.

Patients managed at VHA centers in rural locations were nearly half as likely to undergo testing as patients managed at nonrural centers. The number of patients with treatment-resistant hypertension seen by a physician or at a center had no significant relationship to PA testing frequency.

The study received no commercial funding. Dr. Cohen has disclosed no relevant financial relationships.

People with obesity who lost weight as a result of bariatric surgery and who subsequently contracted COVID-19 were less likely to be admitted to the hospital for COVID, and the disease was less severe than among COVID patients with obesity who had not undergone the surgery, a new retrospective analysis shows.

The research was published in Surgery for Obesity and Related Diseases.

Because obesity is a well-known risk factor for poor COVID-19 outcomes, Ali Aminian, MD, Bariatric and Metabolic Institute, Cleveland Clinic, and colleagues decided to study whether weight-loss surgery had a bearing on outcomes of patients with COVID-19.

They matched 33 COVID-19 patients who had undergone metabolic surgery with 330 control patients with obesity who were infected with the virus during the first wave of the pandemic.

Surgery was associated with a 69% reduction in the risk of being hospitalized as a result of COVID-19. None of the surgery patients required intensive care, mechanical ventilation, or dialysis, and none died.

“Patients after bariatric surgery become significantly healthier and can fight the virus better,” said Dr. Aminian in a statement from his institution. “If confirmed by future studies, this can be added to the long list of health benefits of bariatric surgery.”
 

COVID-19 is a wake-up call for the consequences of obesity

Dr. Aminian said in an interview that COVID-19 is a “wake-up call to show the public and health care professionals that obesity is a major health problem and has multiple health consequences.”

More than 300 articles in the literature show that obesity is a major risk factor for poor outcomes following COVID-19 infection. Dr. Aminian said the pandemic has “improved public awareness about the consequences of obesity.”

Compared with last year at his institution, the intake of new patients “who would like to join a program to have surgery or have some tools to help them to lose weight is almost double,” he noted.

Furthermore, referrals to their unit from primary care physicians, as well as from endocrinologists and cardiologists, for bariatric surgery nearly doubled in recent months.

Although the unit had to stop all bariatric surgeries for around 6 weeks in April because of COVID-19, it has performed the same number of procedures this year as in 2019 and 2018.

Because of the recent surge in COVID cases in Ohio, bariatric procedures are once again on hold. “Elective operations that require hospital beds after surgery have been paused to provide beds for patients who have COVID-19,” he explained.
 

Small sample size, study should be repeated

For their study, Dr. Aminian and colleagues examined the records of 4,365 patients at the Cleveland Clinic Health System who tested positive for the virus between March 8 and July 22, 2020.

Of these, 1,003 had a body mass index of at least 35 mg/kg2; 482 had a BMI of at least 40. The team identified 33 patients who had previously undergone metabolic surgery, comprising 20 sleeve gastrectomies and 13 Roux-en-Y gastric bypasses.

The surgical patients were propensity matched in a 1:10 ratio with nonsurgical control patients with a BMI of at least 40. The patients were matched on the basis of age, sex, ethnicity, location, smoking status, and history of chronic obstructive pulmonary disease.

The mean BMI of surgical patients was 49.1 before their procedure. It fell to 37.2 by the time they tested positive for COVID-19. This compares with an average of 46.7 in the control group at the time they tested positive for the virus.

The team found that 18.2% of metabolic surgery patients were admitted to hospital versus 42.1% of control patients (P = .013).

Moreover, metabolic surgery patients did not require admission to the intensive care unit, nor did they require mechanical ventilation or dialysis, and none died. This compares with 13.0% (P = .021), 6.7% (P = .24), 1.5%, and 2.4%, respectively, of patients in the control group.

Multivariate analysis indicated that prior metabolic surgery was associated with lower hospital admission, at an odds ratio of 0.31 (P = .028), in comparison with control patients with obesity.

Acknowledging the limited sample size of their study, the team wrote: “As this study reflects findings early in the course of the pandemic, it will be of interest to repeat this study with larger data sets and later in the course of the pandemic.”
 

Continue as many aspects of obesity management as possible during pandemic

Dr. Aminian underlined that, for him, the take-home message from the study is that health care professionals should “ideally” continue all aspects of obesity management during the pandemic, including “medical management, behavioral therapy, lifestyle changes, and access to bariatric surgery.”

This is despite the fact that insurance coverage for bariatric surgery has “always been a challenge for many patients, since many insurance plans do not cover” bariatric procedures, he noted.

In July, the American Society for Metabolic and Bariatric Surgery issued a statement declaring that obesity surgery should not be considered an elective procedure and should be resumed as soon as it’s safe to do so during any resurgence of the COVID-19 pandemic.

The authors disclosed no relevant financial relationships.

Those who are found to have type 2 diabetes at a younger age face “hidden” dangers. The issue is becoming more and more important, “since new diagnoses in this younger age group continue to rise,” said the authors of a new study, led by Natalie Nanayakkara, MD.

They believe clinical approaches should be based on age at diagnosis. The results of their new meta-analysis, published online in Diabetologia, reveal the extent of the problem.

Believed to be the first systematic review of its kind, the study showed that the younger the age at diagnosis of type 2 diabetes, the greater the risks of dying and of having either microvascular or macrovascular complications each subsequent year (adjusted for current age).

“This difference in risk between younger and older people in terms of absolute versus lifetime risks of type 2 diabetes complications should perhaps be recognized in diabetes management guidelines,” wrote Dr. Nanayakkara, an endocrinologist at Monash University, Melbourne, and colleagues.

Those diagnosed at younger ages are more likely to develop complications that cause greater disability and lead to loss of productivity compared with people diagnosed at an older age, they stressed.

Hence, they suggested “a greater emphasis on preventive measures for younger people with type 2 diabetes,” with “early intensive multifactorial risk factor intervention ... sustained long term to minimize risks over time.”
 

Large dataset: Use age at diagnosis to risk stratify patients

Rates of type 2 diabetes have increased in all age groups and virtually all countries over the past 3 decades. Particularly worrying is a trend toward increased rates among adults aged 20-44 years. The increases are associated with higher rates of overweight and obesity, poor diet, and decreasing levels of physical activity, numerous studies have shown.

But few studies have examined the association between age at diagnosis and subsequent complications from type 2 diabetes, the authors noted.

Their review included 26 observational studies involving more than one million individuals from 30 countries in the Asia Pacific, Europe, and North America. The investigators found that each 1-year increase in age at diabetes diagnosis was significantly associated with a 4%, 3%, and 5% decreased risk for all-cause mortality, macrovascular disease, and microvascular disease, respectively, adjusted for current age (all P < .001).

Similar decreases in risk per 1-year increase in age at diabetes diagnosis were seen for coronary heart disease (2%), cerebrovascular disease (2%), peripheral vascular disease (3%), retinopathy (8%), nephropathy (6%), and neuropathy (5%); all associations were significant (P < .001).

Dr. Nanayakkara and colleagues noted that current treatment guidelines are limited in that they’re related to the management of patients with suboptimal blood glucose control, and there is no way to predict which people require intensified treatment.

Therefore, they said, “refined stratification using age at diagnosis may provide a method of identifying, at diagnosis, those at greatest risk of complications who would most benefit from targeted, individualized treatment regimens.”

Awareness of this “hidden” danger to younger adults with type 2 diabetes is becoming more and more important, because such cases continue to rise, they reiterated.

They also advised that “public health measures to delay and/or prevent the onset of type 2 diabetes until older age may yield benefits by reducing the duration of diabetes and the burden of complications.”

Dr. Nanayakkara disclosed no relevant financial relationships.
