Physicians could be doing a better job of counseling patients with obesity and overweight on weight loss and fertility. A study of 48 women seeking infertility care at a large academic center found that less than half received advice on weight loss from their primary ob.gyn. prior to referral for infertility treatment.

Patients are thinking about this – many attempt to lose weight independently of support from their health care providers, said lead study author Margaret R. O’Neill, MD, a resident at the University of Massachusetts Medical Center in Worcester. Dr. O’Neill discussed these results at the American Society of Reproductive Medicine’s 2021 meeting.

Nearly half of all U.S. women of reproductive age have overweight or obesity, with a body mass index of >25 kg/m². Menstrual irregularity, ovulatory dysfunction, reduced fecundity, and lower efficacy of infertility treatment are some of the consequences of obesity on fertility, said Dr. O’Neill. Obesity also affects the health of expectant mothers and fetuses, increasing the likelihood of gestational diabetes, preterm delivery, and preeclampsia, and increased incidence of fetal anomalies.

“Unfortunately, even though the prevalence of obesity has been increasing substantially in our country, there’s not excellent rates of this being addressed by physicians,” said Dr. O’Neill. BMI is often left out of documentation and rates of referrals to weight loss specialists are also low.

Conversations have been taking place about IVF centers instituting different BMI cutoffs for certain types of assisted reproductive technology, she noted.

Dr. O’Neill and her colleagues undertook a survey to see what advice community providers were dispensing about weight management on fertility.
 

Infertility specialists offer the most guidance

The prospective study included 48 nonpregnant women of reproductive age women presenting for IVF who needed an anesthesia consultation because of elevated BMI (> 35) prior to initiation of IVF. Mean age was 36 years and mean BMI was 38.5. More than 70% of the patients were White and they were predominantly English speakers.

All participants had attempted weight loss, including an attempt in the last year, and 93.8% reported trying to lose weight in the last year. On average, patients weighed about 20 pounds less than their heaviest adult weight. Nineteen percent of the participants were at their heaviest adult weight.

While 60% said they’d received weight loss/infertility counseling by any health care provider, just 41.7% reported that their primary ob.gyn. counseled them about weight loss before referring them for treatment. Infertility specialists seem to provide the most assistance: Nearly 70% of the respondents said they’ve been counseled by these providers.

Women with a higher-than-average BMI (39) were more likely to report a referral to weight loss counseling compared with women not referred (37.9, P = .2). 

Investigators also asked patients about their knowledge of obesity and its relationship to other health conditions. About 90% understood that infertility and excess weight were related. Overall, they were less sure about the link between obesity and still birth, breast cancer, and birth defects. Only 37% were able to identify a normal BMI range.
 

Avoiding a touchy subject

BMI is a highly sensitive area for many women, despite its detrimental effect on fertility, Mark P. Trolice, MD, professor of obstetrics and gynecology at the University of Central Florida and director of the IVF Center in Orlando, said in an interview.

“By the time their journey has led them to an infertility specialist, most women are very anxious to begin treatment,” said Dr. Trolice, who was not involved in the survey. These patients, however, could interpret any medical advice to achieve a more optimal BMI and healthier lifestyle as a negative judgment that could delay their goal of having a healthy child, he said.

Physicians in turn may avoid these conversations because they don’t want to encourage the ire of patients and/or risk a negative online rating review, he added.

Don’t say ‘just lose weight’

When asked what type of counseling works best, many said that nonspecific recommendations such as “you need to lose weight” or “exercise more” were the least helpful. Targeted advice such as “avoid eating at night and take walks every day,” works more effectively. “Any kind of referral to a bariatrics team or weight loss program was seen as helpful by patients,” said Dr. O’Neill.

Suggestions that considered the difficulty of this process, such as seeking therapy, were also helpful. “Patients appreciated empathy, compassion, and encouragement” from their physicians, she said.
 

The role of physicians in weight loss

Physicians can make a difference. Studies show that patients who received weight loss counseling were more likely to attempt weight loss and report clinically significant weight loss.

The American College of Obstetricians and Gynecologists and ASRM recommend counseling patients with overweight and obesity to lose weight before getting pregnant. A modest weight loss of 10% is associated with improved ovulatory function and higher pregnancy rates, said Dr. O’Neill.

“Appropriately, the infertility specialist should strongly recommend [that women who are obese] obtain a more optimal BMI prior to fertility treatment. While there is no guarantee of decreased infertility and decreased pregnancy complications following weight loss, a lower BMI improves outcomes,” said Dr. Trolice.

Future research should address the fertility outcomes of women who have been counseled by their providers to lose weight and the most effective method of counseling, noted Dr. O’Neill. “We have to find the best ways to address this at each fertility institution.”

The study had limited generalizability because of its narrow patient population and regional differences in access to insurance and weight loss specialists. COVID-19 also reduced the sample size, said Dr. O’Neill. She noted that patient perceptions might not equate with actual counseling delivered.

Dr. O’Neill and Dr. Trolice had no disclosures.

Calculating the estimated glucose disposal rate (eGDR) as a proxy for the level of insulin resistance may be useful way to determine if someone with type 2 diabetes (T2D) is at risk for having a first stroke, Swedish researchers have found.

purestock/Thinkstock

In a large population-based study, the lower the eGDR score went, the higher the risk for having a first stroke became.

The eGDR score was also predictive of the chance of dying from any or a cardiovascular cause, Alexander Zabala, MD, reported at the annual meeting of the European Association for the Study of Diabetes (Abstract OP 01-4).

The link between insulin resistance and an increased risk for stroke has been known for some time, and not just in people with T2D. However, the current way of determining insulin resistance is not suitable for widespread practice.

“The goal standard technique for measuring insulin resistance is the euglycemic clamp method,” said Dr. Zabala, an internal medical resident at Södersjukhuset hospital and researcher at the Karolinska Institutet in Stockholm.

“For that reason, [the eGDR], a method based on readily available clinical factors – waist circumference, hypertension, and glycosylated hemoglobin was developed,” he explained. Body mass index can also be used in place of waist circumference, he qualified.

The eGDR has already been proven to be very precise in people with type 1 diabetes, said Dr. Zabala, and could be an “excellent tool to measure insulin resistance in a large patient population.”
 

Investigating the link between eGDR and first stroke risk

The aim of the study he presented was to see if changes in the eGDR were associated with changes in the risk of someone with T2D experiencing a first stroke, or dying from a cardiovascular or other cause.

An observational cohort was formed by first considering data on all adult patients with T2D who were logged in the Swedish National Diabetes Registry (NDR) during 2004-2016. Then anyone with a history of stroke, or with any missing data on the clinical variables needed to calculate the eGDR, were excluded.

This resulted in an overall population of 104,697 individuals, aged a mean of 63 years, who had developed T2D at around the age of 59 years. About 44% of the study population were women. The mean eGDR for the whole population was 5.6 mg/kg per min.

The study subjects were grouped according to four eGDR levels: 24,706 were in the lowest quartile of eGDR (less than 4 mg/kg per min), signifying the highest level of insulin resistance, and 18,762 were in the upper quartile of eGDR (greater than 8 mg/kg per min), signifying the lowest level of insulin resistance. The middle two groups had an eGDR between 4 and 6 mg/kg per min (40,187), and 6 and 8 mg/kg/min (21,042).

Data from the NDR were then combined with the Swedish Cause of Death register, the Swedish In-patient Care Diagnoses registry, and the Longitudinal Database for Health Insurance and Labour Market Studies (LISA) to determine the rates of stroke, ischemic stroke, hemorrhagic stroke, all-cause mortality, and cardiovascular mortality.
 

Increasing insulin resistance ups risk for stroke, death

After a median follow-up of 5.6 years, 4% (4,201) of the study population had had a stroke.

“We clearly see an increased occurrence of first-time stroke in the group with the lowest eGDR, indicating worst insulin resistance, in comparison with the group with the highest eGDR, indicating less insulin resistance,” Dr. Zabala reported.

After adjustment for potential confounding factors, including age at baseline, gender, diabetes duration, among other variables, the risk for stroke was lowest in those with a high eGDR value and highest for those with a low eGDR value.

Using individuals with the lowest eGDR (less than 4 mg/kg per min) and thus greatest risk of stroke as the reference, adjusted hazard ratios (aHR) for first-time stroke were: 0.60, 0.68, and 0.77 for those with an eGDR of greater than 8, 6-8, and 4-6 mg/kg per min, respectively.

The corresponding values for risk of ischemic stroke were 0.55, 0.68, and 0.75. Regarding hemorrhagic stroke, there was no statistically significant correlation between eGDR levels and stroke occurrence. This was due to the small number of cases recorded.

As for all-cause and cardiovascular mortality, a similar pattern was seen, with higher rates of death linked to increasing insulin resistance. Adjusted hazard ratios according to increasing insulin resistance (decreasing eGDR scores) for all-cause death were 0.68, 0.75, and 0.82 and for cardiovascular mortality were 0.65, 0.75, and 0.82.

A sensitivity analysis, using BMI instead of waist circumference to calculate the eGDR, showed a similar pattern, and “interestingly, a correlation between eGDR levels and risk of hemorrhagic stroke.” Dr. Zabala said.
 

Limitations and take-homes

Of course, this is an observational cohort study, so no conclusions on causality can be made and there are no data on the use of anti-diabetic treatments specifically. But there are strengths such as covering almost all adults with T2D in Sweden and a relatively long-follow-up time.

The findings suggest that “eGDR, which may reflect insulin resistance may be a useful risk marker for stroke and death in people with type 2 diabetes,” said Dr. Zabala.

“You had a very large cohort, and that certainly makes your results very valid,” observed Peter Novodvorsky, MUDr. (Hons), PhD, MRCP, a consultant diabetologist in Trenčín, Slovakia.

Dr. Novodvorsky, who chaired the session, picked up on the lack of information about how many people were taking newer diabetes drugs, such as the glucagon-like peptide 1 receptor antagonists and sodium glucose-lowering transport 2 inhibitors.

“As we all know, these might have protective effects which are not necessarily related to the glucose lowering or insulin resistance-lowering” effects, so could have influenced the results. In terms of how practical the eGDR is for clinical practice, Dr. Zabala observed in a press release: “eGDR could be used to help T2D patients better understand and manage their risk of stroke and death. 

“It could also be of importance in research. In this era of personalized medicine, better stratification of type 2 diabetes patients will help optimize clinical trials and further vital research into treatment, diagnosis, care and prevention.”

The research was a collaboration between the Karolinska Institutet, Gothenburg University and the Swedish National Diabetes Registry. Dr. Zabala and coauthors reported having no conflicts of interest.

A sensitivity analysis, using BMI instead of waist circumference to calculate the eGDR, showed a similar pattern, and “interestingly, a correlation between eGDR levels and risk of hemorrhagic stroke.” Dr. Zabala said.
 

Limitations and take-homes

Of course, this is an observational cohort study, so no conclusions on causality can be made and there are no data on the use of anti-diabetic treatments specifically. But there are strengths such as covering almost all adults with T2D in Sweden and a relatively long-follow-up time.

The findings suggest that “eGDR, which may reflect insulin resistance may be a useful risk marker for stroke and death in people with type 2 diabetes,” said Dr. Zabala.

“You had a very large cohort, and that certainly makes your results very valid,” observed Peter Novodvorsky, MUDr. (Hons), PhD, MRCP, a consultant diabetologist in Trenčín, Slovakia.

Dr. Novodvorsky, who chaired the session, picked up on the lack of information about how many people were taking newer diabetes drugs, such as the glucagon-like peptide 1 receptor antagonists and sodium glucose-lowering transport 2 inhibitors.

“As we all know, these might have protective effects which are not necessarily related to the glucose lowering or insulin resistance-lowering” effects, so could have influenced the results. In terms of how practical the eGDR is for clinical practice, Dr. Zabala observed in a press release: “eGDR could be used to help T2D patients better understand and manage their risk of stroke and death. 

“It could also be of importance in research. In this era of personalized medicine, better stratification of type 2 diabetes patients will help optimize clinical trials and further vital research into treatment, diagnosis, care and prevention.”

The research was a collaboration between the Karolinska Institutet, Gothenburg University and the Swedish National Diabetes Registry. Dr. Zabala and coauthors reported having no conflicts of interest.

The new breakfast of champions

We love a good ranking system here at LOTME world headquarters, especially the food-based ones. Luckily for us (and our readers), a new study published in Nature Food offers a food-based ranking system.

Sadly, unlike the last food-related ranking we covered, the Food Compass doesn’t tell you how much life you gain or lose from each food you eat down to the precise minute. Instead, it favors a more simple rating system from 1 to 100, with healthier foods scoring higher, and even incorporates mixed foods, not just single ingredients. This makes it better at assessing and comparing food combinations, rather than trying to mix and match the many ingredients that go into even relatively simple recipes.

The top and bottom of the rankings contain the usual suspects. Legumes and nuts, at 78.6, had the highest average score among the broad food groups, followed by fruits and then vegetables. Rounding out the bottom were sweets and savory snacks at 16.4. Among the individual foods, there were perfect scores in both directions: 100 for raw raspberries, while instant noodle soup and nonchocolate, ready-to-eat, nonfat pudding (very specific there) each earned a 1.

There are a few surprises in between. Nonfat cappuccino received a green light from the investigators, great news for the coffee drinkers out there. A serving of sweet potato chips scored better than a simple grilled chicken breast, and a slice of pizza, loaded up with extra meat and a thick crust, is still more nutritious than a bowl of corn flakes.

Neither is good for you, of course, but we’re still going to take this as a sign that pizza is the ideal breakfast food. Add that to your morning coffee, and you’re ready to start the day. Move over Wheaties, there’s a new breakfast of champions.
 

COVID-19 resisters, please step forward

Some people have all the luck with good genes, both inside and out.

Genetically speaking, humans are 99.9% the same, but that 0.1% is where things get interesting. Because of that 0.1% difference, some people are more likely to contract diseases such as HIV, while others might be more resistant. These small differences in genetic code could be the key to finding treatments for COVID-19.

“The introduction of SARS-CoV-2 to a naive population, on a global scale, has provided yet another demonstration of the remarkable clinical variability between individuals in the course of infection, ranging from asymptomatic infections to life-threatening disease,” the researchers said in Nature Immunology.

The investigators have been scouring the world to find people who might be resistant to SARS-CoV-2 and have enrolled over 400 individuals in a “dedicated resistance study cohort,” according to ScienceAlert.

The investigators are looking at households in which families were infected but one member did not show severe symptoms, or for individuals who have been around the virus multiple times and haven’t contracted it. They are also looking at blood types.

Enrollment is ongoing, so if you’ve been in contact with COVID-19 multiple times and have not gotten sick, scientists would like to hear from you.
 

Better living through parasitization

How would you like to triple your life span, while maintaining a youthful appearance and gaining special social standing and privileges?

Sounds pretty good, right, so what’s the catch? Well, you have to be infected with a tapeworm ... and you have to be an ant.

If you are an ant, here’s the deal: Workers of the species Temnothorax nylanderi that have tapeworms live much longer than uninfected workers, and while living out those longer lives they do less work and receive gifts of food.

In a study conducted at Johannes Gutenberg University in Mainz, Germany, infected ants’ metabolic rates and lipid levels were similar to those of younger ants, and they appeared to remain in a permanent juvenile stage as a result of the infection, the investigators reported.

They tracked Temnothorax colonies for 3 years, at which point 95% of the uninfected workers had died but over half of the infected ants were still alive. Pretty great, right? Wrong. There was no joy in antville, for the uninfected workers had struck out. “Strained by the additional burden of their wormed-up nestmates, they seemed to be shunting care away from their queen. They were dying sooner than they might have if the colonies had remained parasite-free,” according to an article in the Atlantic.

Does this situation seem just a wee bit familiar? A small group lives longer, healthier lives and enjoys special privileges while the majority of that society works harder to support them? We’ll put it into the form of a chicken-and-egg argument: Which came first, the tapeworms or the one-percenters?
 

Laughing the pandemic stress away

Doomscrolling on social media has become one of the world’s favorite pastimes during the pandemic, but research shows that those memes about COVID-19 might combat the doom and gloom of the outside world.

A study recently published in Psychology of Popular Media showed that viewing memes, specifically those that were COVID-19 related, actually lessened the stress of the pandemic.

The researchers conducted a survey of 748 people aged 18-88 years. Each participant viewed three memes with text or three memes with text but no images. All three memes had similar cuteness levels (baby or adult), subject (animal or human), and caption (COVID-19–related or not). The participants were then asked to report on their stress levels and feelings before and after the memes.

The people who looked at memes felt less stressed and a higher humor level, especially the participants who received the COVID-19 memes. Study Finds said that they had more “pandemic-coping confidence” than those who got regular memes.

“While the World Health Organization recommended that people avoid too much COVID-related media for the benefit of their mental health, our research reveals that memes about COVID-19 could help people feel more confident in their ability to deal with the pandemic,” lead author Jessica Gall Myrick, PhD, said in a written statement. “The positive emotions associated with this type of content may make people feel psychologically safer and therefore better able to pay attention to the underlying messages related to health threats.”

So if you think you’ve been wasting time looking at memes during this pandemic, think again. It actually might keep you sane. Keep on scrolling!

The U.S. Food and Drug Administration (FDA) has authorized booster doses for the Moderna and Johnson & Johnson COVID-19 vaccines, while also allowing boosters to be given interchangeably with any of the other vaccines, in people who are eligible to get them.

The move to amend the Emergency Use Authorization for these vaccines gives the vaccine experts on the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices latitude to recommend a mix-and-match strategy if they feel the science supports it.

The committee convenes Oct. 21 for a day-long meeting to make its recommendations for additional doses.

People who’ve previously received two doses of the Moderna mRNA vaccine, which is now called Spikevax, are eligible for a third dose of any COVID-19 vaccine if they are 6 months past their second dose and are:

• 65 years of age or older
• 18 to 64 years of age, but at high risk for severe COVID-19 because of an underlying health condition
• 18 to 64 years of age and at high risk for exposure to the SARS-CoV-2 virus because they live in a group setting, such as a prison or care home, or work in a risky occupation, such as healthcare

People who’ve previously received a dose of the Johnson & Johnson vaccine are eligible for a second dose of any COVID-19 vaccine if they are over the age of 18 and at least 2 months past their vaccination.

“Today’s actions demonstrate our commitment to public health in proactively fighting against the COVID-19 pandemic,” said Acting FDA Commissioner Janet Woodcock, MD, in a news release. “As the pandemic continues to impact the country, science has shown that vaccination continues to be the safest and most effective way to prevent COVID-19, including the most serious consequences of the disease, such as hospitalization and death.

“The available data suggest waning immunity in some populations who are fully vaccinated. The availability of these authorized boosters is important for continued protection against COVID-19 disease.”

Although early menopause is linked to increased risks in bone loss and fracture, new research indicates that, even among the majority of women who have menopause after age 45, the time since the final menstrual period can be a stronger predictor than chronological age for key risks in bone health and fracture.

Steve Debenport/Getty Images

In a large longitudinal cohort, the number of years since a woman’s final menstrual period specifically showed a stronger association with femoral neck bone mineral density (BMD) than chronological age, while an earlier age at menopause – even among those over 45 years, was linked to an increased risk of fracture.

“Most of our clinical tools to predict osteoporosis-related outcomes use chronological age,” first author Albert Shieh, MD, told this news organization.

“Our findings suggest that more research should be done to examine whether ovarian age (time since final menstrual period) should be used in these tools as well.”

An increased focus on the significance of age at the time of the final menstrual period, compared with chronological age, has gained interest in risk assessment because of the known acceleration in the decline of BMD that occurs 1 year prior to the final menstrual period and continues at a rapid pace for 3 years afterwards before slowing.

To further investigate the association with BMD, Dr. Shieh, an endocrinologist specializing in osteoporosis at the University of California, Los Angeles, and his colleagues turned to data from the Study of Women’s Health Across the Nation (SWAN), a longitudinal cohort study of ambulatory women with pre- or early perimenopausal baseline data and 15 annual follow-up assessments.

Outcomes regarding postmenopausal lumbar spine (LS) or femoral neck (FN) BMD were evaluated in 1,038 women, while the time to fracture in relation to the final menstrual period was separately evaluated in 1,554 women.

In both cohorts, the women had a known final menstrual period at age 45 or older, and on average, their final menstrual period occurred at age 52.

After a multivariate adjustment for age, body mass index, and various other factors, they found that each additional year after a woman’s final menstrual period was associated with a significant (0.006 g/cm²) reduction in postmenopausal lumbar spine BMD and a 0.004 g/cm² reduction femoral neck BMD (both P < .0001).

Conversely, chronological age was not associated with a change in femoral neck BMD when evaluated independently of years since the final menstrual period, the researchers reported in the Journal of Clinical Endocrinology and Metabolism.

Regarding lumbar spine BMD, chronological age was unexpectedly associated not just with change, but in fact with increases in lumbar spine BMD (P < .0001 per year). However, the authors speculate the change “is likely a reflection of age-associated degenerative changes causing false elevations in BMD measured by dual-energy x-ray absorptiometry.”

Fracture risk with earlier menopause

In terms of the fracture risk analysis, despite the women all being aged 45 or older, earlier age at menopause was still tied to an increased risk of incident fracture, with a 5% increase in risk for each earlier year in age at the time of the final menstrual period (P = .02).

Compared with women who had their final menstrual period at age 55, for instance, those who finished menstruating at age 47 had a 6.3% greater 20-year cumulative fracture risk, the authors note.

While previous findings from the Malmo Perimenopausal Study showed menopause prior to the age of 47 to be associated with an 83% and 59% greater risk of densitometric osteoporosis and fracture, respectively, by age 77, the authors note that the new study is unique in including only women who had a final menstrual period over the age of 45, therefore reducing the potential confounding of data on women under 45.

The new results “add to a growing body of literature suggesting that the endocrine changes that occur during the menopause transition trigger a pathophysiologic cascade that leads to organ dysfunction,” the authors note.

In terms of implications in risk assessment, “future studies should examine whether years since the final menstrual period predicts major osteoporotic fractures and hip fractures, specifically, and, if so, whether replacing chronological age with years since the final menstrual period improves the performance of clinical prediction tools, such as FRAX [Fracture Risk Assessment Tool],” they add.

Addition to guidelines?

Commenting on the findings, Peter Ebeling, MD, the current president of the American Society of Bone and Mineral Research, noted that the study importantly “confirms what we had previously anticipated, that in women with menopause who are 45 years of age or older a lower age of final menstrual period is associated with lower spine and hip BMD and more fractures.”

“We had already known this for women with premature ovarian insufficiency or an early menopause, and this extends the observation to the vast majority of women – more than 90% – with a normal menopause age,” said Dr. Ebeling, professor of medicine at Monash Health, Monash University, in Melbourne.

Despite the known importance of the time since final menstrual period, guidelines still focus on age in terms of chronology, rather than biology, emphasizing the risk among women over 50, in general, rather than the time since the last menstrual period, he noted.

“There is an important difference [between those two], as shown by this study,” he said. “Guidelines could be easily adapted to reflect this.”

Specifically, the association between lower age of final menstrual period and lower spine and hip BMD and more fractures requires “more formal assessment to determine whether adding age of final menstrual period to existing fracture risk calculator tools, like FRAX, can improve absolute fracture risk prediction,” Dr. Ebeling noted.

The authors and Dr. Ebeling had no disclosures to report.

Although early menopause is linked to increased risks in bone loss and fracture, new research indicates that, even among the majority of women who have menopause after age 45, the time since the final menstrual period can be a stronger predictor than chronological age for key risks in bone health and fracture.

To further investigate the association with BMD, Dr. Shieh, an endocrinologist specializing in osteoporosis at the University of California, Los Angeles, and his colleagues turned to data from the Study of Women’s Health Across the Nation (SWAN), a longitudinal cohort study of ambulatory women with pre- or early perimenopausal baseline data and 15 annual follow-up assessments.

Outcomes regarding postmenopausal lumbar spine (LS) or femoral neck (FN) BMD were evaluated in 1,038 women, while the time to fracture in relation to the final menstrual period was separately evaluated in 1,554 women.

In both cohorts, the women had a known final menstrual period at age 45 or older, and on average, their final menstrual period occurred at age 52.

After a multivariate adjustment for age, body mass index, and various other factors, they found that each additional year after a woman’s final menstrual period was associated with a significant (0.006 g/cm²) reduction in postmenopausal lumbar spine BMD and a 0.004 g/cm² reduction femoral neck BMD (both P < .0001).

Conversely, chronological age was not associated with a change in femoral neck BMD when evaluated independently of years since the final menstrual period, the researchers reported in the Journal of Clinical Endocrinology and Metabolism.

Regarding lumbar spine BMD, chronological age was unexpectedly associated not just with change, but in fact with increases in lumbar spine BMD (P < .0001 per year). However, the authors speculate the change “is likely a reflection of age-associated degenerative changes causing false elevations in BMD measured by dual-energy x-ray absorptiometry.”

Fracture risk with earlier menopause

In terms of the fracture risk analysis, despite the women all being aged 45 or older, earlier age at menopause was still tied to an increased risk of incident fracture, with a 5% increase in risk for each earlier year in age at the time of the final menstrual period (P = .02).

Compared with women who had their final menstrual period at age 55, for instance, those who finished menstruating at age 47 had a 6.3% greater 20-year cumulative fracture risk, the authors note.

While previous findings from the Malmo Perimenopausal Study showed menopause prior to the age of 47 to be associated with an 83% and 59% greater risk of densitometric osteoporosis and fracture, respectively, by age 77, the authors note that the new study is unique in including only women who had a final menstrual period over the age of 45, therefore reducing the potential confounding of data on women under 45.

The new results “add to a growing body of literature suggesting that the endocrine changes that occur during the menopause transition trigger a pathophysiologic cascade that leads to organ dysfunction,” the authors note.

In terms of implications in risk assessment, “future studies should examine whether years since the final menstrual period predicts major osteoporotic fractures and hip fractures, specifically, and, if so, whether replacing chronological age with years since the final menstrual period improves the performance of clinical prediction tools, such as FRAX [Fracture Risk Assessment Tool],” they add.

Addition to guidelines?

Commenting on the findings, Peter Ebeling, MD, the current president of the American Society of Bone and Mineral Research, noted that the study importantly “confirms what we had previously anticipated, that in women with menopause who are 45 years of age or older a lower age of final menstrual period is associated with lower spine and hip BMD and more fractures.”

“We had already known this for women with premature ovarian insufficiency or an early menopause, and this extends the observation to the vast majority of women – more than 90% – with a normal menopause age,” said Dr. Ebeling, professor of medicine at Monash Health, Monash University, in Melbourne.

Despite the known importance of the time since final menstrual period, guidelines still focus on age in terms of chronology, rather than biology, emphasizing the risk among women over 50, in general, rather than the time since the last menstrual period, he noted.

“There is an important difference [between those two], as shown by this study,” he said. “Guidelines could be easily adapted to reflect this.”

Specifically, the association between lower age of final menstrual period and lower spine and hip BMD and more fractures requires “more formal assessment to determine whether adding age of final menstrual period to existing fracture risk calculator tools, like FRAX, can improve absolute fracture risk prediction,” Dr. Ebeling noted.

The authors and Dr. Ebeling had no disclosures to report.

Although early menopause is linked to increased risks in bone loss and fracture, new research indicates that, even among the majority of women who have menopause after age 45, the time since the final menstrual period can be a stronger predictor than chronological age for key risks in bone health and fracture.

In a large longitudinal cohort, the number of years since a woman’s final menstrual period specifically showed a stronger association with femoral neck bone mineral density (BMD) than chronological age, while an earlier age at menopause – even among those over 45 years, was linked to an increased risk of fracture.

“Most of our clinical tools to predict osteoporosis-related outcomes use chronological age,” first author Albert Shieh, MD, told this news organization.

“Our findings suggest that more research should be done to examine whether ovarian age (time since final menstrual period) should be used in these tools as well.”

A large international team of experts has developed two comprehensive guidelines for diagnosing, evaluating, and managing hypoparathyroidism and hyperparathyroidism, which replace guidelines issued 5 and 7 years ago.

Aliya A. Khan, MD, presented an overview of the hypoparathyroidism guidelines and John P. Bilezikian, MD, presented key aspects of the hyperparathyroidism guidelines at the American Society of Bone and Mineral Research (ASBMR) 2021 Annual Meeting.

The guidelines will be published as 17 articles in two issues of the society’s Journal of Bone and Mineral Research in 2022 – one on hypoparathyroidism and the other on hyperparathyroidism.

The work represents an “unprecedented effort” by more than 100 experts from 16 countries (United States, Canada, Australia, Brazil, China, Denmark, France, Germany, India, Italy, Israel, Lebanon, Singapore, Spain, Sweden, and the United Kingdom), Dr. Bilezikian told this news organization in an interview.

More than 100 international and national endocrine and osteoporosis organizations, societies, and patient advocacy groups from more than 50 countries have expressed interest in endorsing the guidelines.
 

Management of hypoparathyroidism

The new guidelines on hypoparathyroidism replace the guidelines issued in 2016 that were developed at the First International Conference on the Management of Hypoparathyroidism, Dr. Khan, from McMaster University, Hamilton, Ont., said in an email.

There was a need for new hypoparathyroidism guidelines, she explained, because of the better understanding of associated complications, how to predict who will develop hypoparathyroidism postoperatively (and how to prevent this), how and when to investigate a genetic cause further, when to consider parathyroid hormone (PTH) replacement therapy (and the benefits of the various molecules available today as well as those being evaluated in clinical research), and how to diagnose and manage hypoparathyroidism during pregnancy and lactation.

The experts in hypoparathyroidism were divided into four task forces that covered epidemiology and financial burden, etiology and pathophysiology, genetics and diagnosis, and patient evaluation and management.

The guidelines, developed over the past 18 months, provide detailed evidence-based graded (strong to weak) as well as ungraded (current practice) recommendations.

Summarizing a few key takeaways, Dr. Khan noted the guidelines recommend that clinicians treating patients with hypoparathyroidism should:

• Diagnose hypoparathyroidism if serum calcium corrected for albumin is low in the presence of a low or inappropriately normal PTH confirmed on two occasions 2 weeks apart (which may be supported by other specified abnormalities).
• Determine the cause for the hypoparathyroidism (which includes postsurgery, genetic variant, autoimmune, radiation, or idiopathic causes).
• Evaluate target organ damage.
• Try to achieve treatment goals and minimize risks for long-term complications.
• Consider PTH replacement therapy if patients have inadequate control, with symptoms of hypocalcemia or hypercalcemia, high phosphate, kidney disease, or high urine calcium, or poor quality of life. 

The guideline strongly recommends using PTH measurements after total thyroidectomy to try to predict which patients will develop permanent postsurgical hypoparathyroidism.

It provides a clinical approach for establishing the genetic etiology of hypoparathyroidism.

A meta-analysis of 81 studies identified that the most common symptoms/complications of chronic hypoparathyroidism were, in descending order, cataract (24%), infection (18%), nephrolithiasis, renal insufficiency, seizures, depression, ischemic heart disease, and arrhythmias.

Based on the best available evidence, the guideline advises that “clinicians need to carefully determine why a patient has hypoparathyroidism and develop an individualized treatment plan with conventional therapy consisting of calcium, active vitamin D, hydrochlorothiazide, and plain vitamin D,” Dr. Khan continued.

“If a patient has poorly controlled hypoparathyroidism with many symptoms or is not doing well, then clinicians must consider PTH replacement therapy, since this will replace the missing hormone, lower the urine calcium losses, bring the serum calcium back up to the normal reference range, and lower phosphate (which appears to be associated with kidney calcification and may also contribute to basal ganglia calcification and calcium deposits in the eye),” she noted.

The guideline also discusses the optimal way to monitor and treat patients during pregnancy, delivery, and breastfeeding to optimize outcomes for mother and baby. The key points are closer patient monitoring with normalization of calcium, urine calcium, phosphate, and vitamin D.  
 

Management of primary hyperparathyroidism

There was a need to update the previous 2014 guidelines developed at the Fourth International Workshop on the Management of Primary Hyperparathyroidism because, among other things, recent studies have provided new evidence about the different clinical phenotypes of primary hyperparathyroidism and ways the disease affects the skeleton and kidneys, Dr. Bilezikian, from the College of Physicians and Surgeons, Columbia University, New York, explained.

The experts in hyperparathyroidism were divided into four task forces that covered epidemiology, pathophysiology and genetics; classical and nonclassical disease manifestations; surgical aspects; and patient evaluation and management.

As part of these topics, the experts reviewed biochemical, skeletal, and renal findings, nonclassical features (such as neurocognitive complaints), nutritional and pharmacologic approaches, and disease course with or without surgical or medical intervention.

They made recommendations for diagnosis of hypercalcemic and normocalcemic phenotypes, differential diagnosis, evaluation of the skeleton and the kidney, indications for surgery, role of parathyroid imaging, indications for pharmacologic intervention, and monitoring.

“Consider the way this disease has appeared to change in the last 50 years,” said Dr. Bilezikian. In the 1940s, 50s, and 60s, patients with hyperparathyroidism were really sick and had severe bone disease and kidney disease. Then in the 70s, 80s, and 90s, the disease was more often discovered because of a screening test; high serum calcium was a hallmark of finding asymptomatic hyperparathyroidism.

In recent years, hyperparathyroidism is often discovered incidentally, when examining the skeleton or kidneys, he continued.

Primary hyperparathyroidism can now be subdivided into three types: patients who have target organ (kidney, bone) involvement, patients who don’t have this, and patients who have normocalcemic primary hyperparathyroidism.

The guideline discusses new medications that have become available for hyperparathyroidism, as well as surgery (the only cure), including how preoperative imaging can identify the overactive parathyroid gland, and the guidelines go into detail about how to monitor a patient and why a clinician would or would not recommend surgery, Dr. Bilezikian explained.

In the end, treatment is tailored to the individual.

Last, the guideline identifies eight areas where more research is needed.

The guidelines were funded by unrestricted educational grants from Amolyt, Ascendis, Calcilytix, and Takeda. Dr. Khan has reported participating on advisory boards for Alexion, Amgen, Amolyt, and Takeda, being a consultant for Amgen, receiving grants from Alexion, Amgen, Takeda, and Ascendis, being an investigator for Alexion, Amgen, Takeda, Ascendis, and Chugai, and being a speaker for Alexion, Amgen, Takeda, and Ultragenyx. Dr. Bilezikian has reported no relevant financial relationships.

Despite the extensive recent focus on its cost, insulin use in the United States remains dominated by insulin glargine and other analogs, as well as pen devices for delivery, new research shows.

The findings come from a nationally representative audit of outpatient care with input from nearly 5,000 physicians who prescribed insulin to patients with type 2 diabetes in 2016-2020.

The dramatic rise in the price of insulin in the United States has been extensively discussed in recent years, particularly with the newer analogs as compared with older human insulins.

Few studies indicate analog insulins better than human insulins

“Our findings suggest that even with increased public scrutiny for insulin products ... [the market is] dominated by the use of insulin analogs and insulin pen delivery devices, with persistent uptake of newer products as they are approved,” lead author Rita R. Kalyani, MD, told this news organization.

“Though newer insulins offer potentially greater flexibility with reduced hypoglycemia for many patients, they are also much more costly, with minimal to no head-to-head studies suggesting significant differences in glucose-lowering efficacy when compared to human insulins,” she stressed.

“We found it surprising that, despite the much-publicized concerns regarding insulin costs, analog insulins continue to represent more than 80% of insulin visits in the U.S.” added Dr. Kalyani, of the Division of Endocrinology, Diabetes & Metabolism at Johns Hopkins University School of Medicine, Baltimore.

However, as expected, the study also revealed a gradual increased uptake in the use of biosimilar insulins as more have been introduced to the market.

Dr. Kalyani advised, “Clinicians should be aware of their individual prescribing patterns for insulin and consider the affordability of insulin for patients as part of shared decision-making during clinic visits, particularly given the greater financial strain that many patients have faced during the ongoing COVID-19 pandemic and the rising societal costs for diabetes care.”

The research was published online October 12 in JAMA Network Open by Dr. Kalyani and colleagues.

Analogs prevailed, while biosimilar use rose

The data come from the Health National Disease and Therapeutic Index, a quarterly sampling of approximately 4,800 physicians that provides nationally representative diagnostic and prescribing information on patients treated by office-based physicians in the United States.

Overall, there were 27,860,691 insulin treatment visits for type 2 diabetes in 2016-2020. Of those, long-acting analog insulins (glargine [Lantus], detemir [Levemir], and degludec [Tresiba]) accounted for 67.3% of treatment visits in 2016 and 74.8% of treatment visits in 2020.

Rapid-acting insulin analogs (lispro [Humalog], aspart [Novolog], faster aspart [Fiasp], and glulisine [Apidra]) accounted for about 21.2% of visits in 2016 and about 16.5% in 2020.

On the other hand, intermediate- and short-acting human insulins (NPH and regular) accounted for just 3.7% of visits in 2016 and 2.6% in 2020.

Grouped together, the long- and short-acting analogs accounted for 92.7% of visits in 2016 and 86.3% in 2020, while the human insulins represented just 7.3% of visits in 2016 and 5.5% in 2020.

The biosimilar analog insulins (glargine and lispro) first appeared in the database in 2017, accounting for 2.6% of visits that year and 8.2% by 2020.

Overall, the number of visits for insulin treatment declined by 18% between 2016 and 2020, from 6.0 million to 4.9 million. That drop may be due to multiple factors, Dr. Kalyani said.

“Recently updated clinical practice guidelines from professional societies such as the American Diabetes Association recommend the use of glucagon-like peptide-1 (GLP-1) receptor agonists prior to insulin when injectable medications are being considered [for type 2 diabetes],” she noted.

“In addition, during the pandemic, patients may not have been seeing their health care providers for routine diabetes care as often as before ... These and other factors may have contributed to the decrease in insulin visits that we observed.”

By specific insulins, glargine has topped the list all along, accounting for about half of all treatment visits, at 52.6% in 2020. Degludec came in second, at 17.4%, and lispro third, at 9.5%.

Use of pen devices also increased

The proportion of treatment visits for insulin vials/syringes declined from 63.9% in 2016 to 41.1% in 2020, while visits for insulin pens rose from 36.1% to 58.7%.

“Many pens are more costly compared to vials of the same insulin product. Interestingly, some studies have found that use of insulin pens may promote greater patient adherence to insulin and, as a result, more broadly decrease health care costs associated with diabetes. However, we did not specifically investigate the cost of insulin in our study,” Dr. Kalyani noted.

The proportion of visits for “newer” insulins, defined as those approved in 2010 or later, rose from 18.1% in 2016 to 40.9% in 2020, while the concurrent drop for insulins approved prior to 2010 was from 81.9% to 59.1%.

“The findings of our study provide insight into potential drivers of insulin costs in the U.S. and may inform health policy,” the researchers conclude.

Despite the extensive recent focus on its cost, insulin use in the United States remains dominated by insulin glargine and other analogs, as well as pen devices for delivery, new research shows.

The findings come from a nationally representative audit of outpatient care with input from nearly 5,000 physicians who prescribed insulin to patients with type 2 diabetes in 2016-2020.

The dramatic rise in the price of insulin in the United States has been extensively discussed in recent years, particularly with the newer analogs as compared with older human insulins.

Few studies indicate analog insulins better than human insulins

“Our findings suggest that even with increased public scrutiny for insulin products ... [the market is] dominated by the use of insulin analogs and insulin pen delivery devices, with persistent uptake of newer products as they are approved,” lead author Rita R. Kalyani, MD, told this news organization.

“Though newer insulins offer potentially greater flexibility with reduced hypoglycemia for many patients, they are also much more costly, with minimal to no head-to-head studies suggesting significant differences in glucose-lowering efficacy when compared to human insulins,” she stressed.

“We found it surprising that, despite the much-publicized concerns regarding insulin costs, analog insulins continue to represent more than 80% of insulin visits in the U.S.” added Dr. Kalyani, of the Division of Endocrinology, Diabetes & Metabolism at Johns Hopkins University School of Medicine, Baltimore.

However, as expected, the study also revealed a gradual increased uptake in the use of biosimilar insulins as more have been introduced to the market.

Dr. Kalyani advised, “Clinicians should be aware of their individual prescribing patterns for insulin and consider the affordability of insulin for patients as part of shared decision-making during clinic visits, particularly given the greater financial strain that many patients have faced during the ongoing COVID-19 pandemic and the rising societal costs for diabetes care.”

The research was published online October 12 in JAMA Network Open by Dr. Kalyani and colleagues.

Analogs prevailed, while biosimilar use rose

The data come from the Health National Disease and Therapeutic Index, a quarterly sampling of approximately 4,800 physicians that provides nationally representative diagnostic and prescribing information on patients treated by office-based physicians in the United States.

Overall, there were 27,860,691 insulin treatment visits for type 2 diabetes in 2016-2020. Of those, long-acting analog insulins (glargine [Lantus], detemir [Levemir], and degludec [Tresiba]) accounted for 67.3% of treatment visits in 2016 and 74.8% of treatment visits in 2020.

Rapid-acting insulin analogs (lispro [Humalog], aspart [Novolog], faster aspart [Fiasp], and glulisine [Apidra]) accounted for about 21.2% of visits in 2016 and about 16.5% in 2020.

On the other hand, intermediate- and short-acting human insulins (NPH and regular) accounted for just 3.7% of visits in 2016 and 2.6% in 2020.

It’s hard for people to completely escape a history of obesity, even when they later achieve a healthy weight.

American adults who once had obesity but later achieved and maintained a healthy body mass index (BMI) normalized some, but not all, of the excess clinical risk associated with obesity in a review of data collected from about 20,000 people during a series of eight NHANES surveys.

Maia P. Smith, MD, reported the findings at the virtual European Association for the Study of Diabetes (EASD) 2021 Annual Meeting.

“For some conditions, such as hypertension and dyslipidemia, the recovery [following a sharp drop in BMI] appears to be total, while for other conditions, like diabetes, the recovery is probabilistic. Some recover, but some don’t,” explained Dr. Smith in an interview.

“Weight loss reverses all, or essentially all, of the damage done by obesity in some people, but does not cause full reversal of the harm and does not fully resolve [type 2] diabetes in many others,” added Dr. Smith, an epidemiologist in the Department of Public Health and Preventive Medicine at St. George’s University, Grenada.

“The fact that ... analyses comparing formerly obese people to normal weight populations demonstrated improvement in population mean levels of hypertension and dyslipidemia is remarkable,” commented Rebecca T. Emeny, PhD, an epidemiologist at the Dartmouth Institute of Health Policy and Clinical Practice in Lebanon, New Hampshire, who was not involved with Dr. Smith’s study.

“The observation that the individuals who were able to maintain normal weight after past obesity were still at greater risk for diabetes compared with the normal weight group speaks to the recent discussion of obesity as a metabolic disorder rather than a problem of calories in and calories out,” said Dr. Emeny in an interview.

She cited a recent article that proposed a carbohydrate-insulin model for obesity in place of an energy-balance model. This, however, is still somewhat contentious.

Dr. Emeny also cautioned that “the results of this study compare populations. The design and analysis do not allow for interpretation of individual risk resulting from changes in weight.”
 

Those who formerly had obesity can reverse hypertension, dyslipidemia

The study by Dr. Smith and associates used data collected in the National Health and Nutrition Examination Survey (NHANES), which is performed every 2 years by the U.S. Centers for Disease Control and Prevention.

They used data from eight consecutive surveys starting in 1999-2000 and continuing through 2013-2014, yielding data from nearly 40,000 adults who were at least 20 years old.

In addition to the 326 people who formerly had obesity at some time previously during their life (BMI ≥30 kg/m²) but now had a healthy BMI, and 6,235 who were consistently at a healthy BMI, they also included 13,710 people who currently had obesity. They dropped the remaining survey participants who did not fit into one of these three categories.

The participants who formerly had obesity averaged 54 years old, compared with a mean age of 48 years among those with current obesity and 41 years among those who currently had a healthy BMI (who had never had obesity). The results showed no differences by sex, but those who formerly had obesity had a much higher smoking prevalence.

The people who reported a healthy BMI (18.5-24.9 kg/m²) after previously having obesity had current prevalence rates of hypertension and dyslipidemia that were, respectively, 8% and 13% higher than the prevalence rates among adults who consistently maintained a healthy BMI – differences that were not significant.

In contrast, people who had current BMIs that indicated obesity had prevalence rates of hypertension and dyslipidemia that were each a significant threefold higher than those with a healthy BMI.

The 326 respondents who formerly had obesity but now were at a healthy BMI had a threefold higher prevalence of diabetes than did the 6,235 who consistently had maintained a healthy BMI. This was substantially less than the over sevenfold higher prevalence of diabetes among those who currently had obesity compared with those who always had a healthy BMI.

All these analyses were adjusted for the potential confounders of age, sex, smoking history, and ethnicity.
 

‘Quitting’ obesity better than current obesity

The finding that reaching a healthy BMI after a period of obesity could reverse some but not all risks associated with obesity is reminiscent of the effects of smoking, noted Dr. Smith.

“Never is better than ever, but quitting,” or dropping weight to reach a healthy BMI, “is better than current,” she concluded.

But Dr. Emeny said this interpretation, “while motivating and catchy, places emphasis on individual responsibility and choice rather than on social circumstances.”

Social effects “must be considered when evaluating population-level disparities in obesity-related cardiometabolic risk,” cautioned Dr. Emeny.

“’Quitting’ obesity is much more complicated than individual choice or ability.”

Dr. Smith also conceded that her analyses did not correct for the possible confounding effects that changes in diet or physical activity may have had on the observations.

“Neither diet nor physical activity has a well-known summary measure that we could have included as an adjuster,” she explained.

Dr. Smith and Dr. Emeny have reported no relevant financial relationships.

Five years out, sleeve gastrectomy had a lower risk of mortality, complications, and reinterventions than gastric bypass, but there was a higher risk of surgical revision, including conversion to another bariatric surgery, gastrectomy, or anastomotic revision, according to a new analysis.

herjua/Thinkstock

Sleeve gastrectomy has gained rapid popularity, and now represents 60% of all bariatric procedures. It has demonstrated good efficacy and short-term safety, it is easier to perform than laparoscopic Roux-en-Y gastric bypass, and it is a safe option for high-risk patients, authors led by Ryan Howard, MD, of University of Michigan, Ann Arbor, wrote in JAMA Surgery.

Still, there are few comparative data on the long-term efficacy of the two procedures. Randomized, controlled trials have conducted long-term follow-up, but their small size has made it difficult to detect differences in rare outcomes. Observational studies are limited by the potential for bias. A novel approach to limiting bias is instrumental variables analysis, which controls for possible confounding using a factor that impacts treatment choice, but not patient outcome, to control for possible confounders. Studies using this approach confirmed the superior safety profile of sleeve gastrectomy in the short term.

The current study’s authors, used that method to examined 5-year outcomes in a Medicare population, in which obesity and its complications are especially frequent. Partly because of that lack of data, the Medical Evidence Development and Coverage Committee has called for more data in older patients and in patients with disabilities.

The researchers analyzed data from 95,405 Medicare claims between 2012 and 2018, using state-level variation in sleeve gastrectomy as the instrumental variable.

At 5 years, sleeve gastrectomy was associated with a lower cumulative frequency of mortality (4.27%; 95% confidence interval, 4.25%-4.30% vs. 5.67%; 95% CI, 5.63%-5.69%]), complications (22.10%; 95% CI, 22.06%-22.13% vs. 29.03%; 95% CI, 28.99%-29.08%), and reintervention (25.23%; 95% CI, 25.19%-25.27% vs. 33.57%; 95% CI, 33.52%-33.63%). At 5 years, surgical revision was more common in the sleeve gastrectomy group (2.91%; 95% CI, 2.90%-2.93% vs. 1.46%; 95% CI, 1.45%-1.47%).

The sleeve gastrectomy group had lower odds of all-cause hospitalization at 1 year (adjusted hazard ratio, 0.83; 95% CI, 0.80-0.86) and 3 years (aHR, 0.94; 95% CI, 0.90-0.98), as well as emergency department use at 1 year (aHR, 0.87; 95% CI, 0.84-0.90) and 3 years (aHR, 0.93; 95% CI, 0.90-0.97). There was no significant difference between the two groups at 5 years with respect to either outcome.

The effort to understand long-term outcomes of these two procedures has been challenging because follow-up is often incomplete, and because reporting isn’t always standardized, according Anita P. Courcoulas, MD, MPH, and Bestoun Ahmed, MD, in an accompanying editorial in JAMA Surgery. They noted that the differences in mortality is a new finding and the difference in surgical revisions confirmed something often seen in clinical practice. “Overall, these novel methods, which creatively balance unmeasured factors, have succeeded in providing important incremental findings about the long-term comparative safety outcomes between bariatric procedures that will be helpful in clinical practice,” the editorial authors wrote.

The complications discussed in the study are also difficult to interpret, according to Ali Aminian, MD, who is a professor of surgery and director of Bariatric and Metabolic Institute at Cleveland Clinic. They may be related to the surgery, or they may be complications that accrue as patients age. “So that doesn’t mean those were surgical complications, but [the findings are] in line with the other literature that [gastric sleeve] may be safer than gastric bypass, but in a different cohort of patients,” said Dr. Aminian, who was asked to comment.

“I thought it validated that which many of us in clinical practice see on a day to day basis,” said Shanu Kothari, MD, chair of surgery at Prisma Health, and the current president of American Society for Bariatric and Metabolic Surgery. He pointed out that the study was limited by its reliance on administrative claims, which makes it impossible to know the reduction in weight and obesity-related comorbid conditions following the procedures, as well as factors driving individual decisions: A surgeon might offer sleeve to a patient at higher risk of complications, but a gastric bypass to someone with more comorbidities. “What we don’t know is how to interpret this 35,000-foot view of Medicare data to that conversation with the patient sitting right in front of you,” said Dr. Kothari.

The authors similarly cited the “lack of clinical granularity in administrative claims data” among study limitations, as well as how the use of instrumental variables may leave the findings less applicable to patients more strongly indicated for one procedure over the other.

“Longer-term randomized clinical trials and observational studies are warranted to confirm these findings,” the study authors concluded. “Understanding the risk profile of various bariatric operations may further help patients and surgeons make the most appropriate decisions regarding plans of care.”

The study was funded by the National Institute of Diabetes and Digestive and Kidney Diseases. Some study authors and editorialists reported funding from various groups and institutions, such as the National Institutes of Health and the VA Ann Arbor Health System. Dr. Kothari and Dr. Aminian have no relevant financial disclosures.

Five years out, sleeve gastrectomy had a lower risk of mortality, complications, and reinterventions than gastric bypass, but there was a higher risk of surgical revision, including conversion to another bariatric surgery, gastrectomy, or anastomotic revision, according to a new analysis.

Sleeve gastrectomy has gained rapid popularity, and now represents 60% of all bariatric procedures. It has demonstrated good efficacy and short-term safety, it is easier to perform than laparoscopic Roux-en-Y gastric bypass, and it is a safe option for high-risk patients, authors led by Ryan Howard, MD, of University of Michigan, Ann Arbor, wrote in JAMA Surgery.

Still, there are few comparative data on the long-term efficacy of the two procedures. Randomized, controlled trials have conducted long-term follow-up, but their small size has made it difficult to detect differences in rare outcomes. Observational studies are limited by the potential for bias. A novel approach to limiting bias is instrumental variables analysis, which controls for possible confounding using a factor that impacts treatment choice, but not patient outcome, to control for possible confounders. Studies using this approach confirmed the superior safety profile of sleeve gastrectomy in the short term.

The current study’s authors, used that method to examined 5-year outcomes in a Medicare population, in which obesity and its complications are especially frequent. Partly because of that lack of data, the Medical Evidence Development and Coverage Committee has called for more data in older patients and in patients with disabilities.

The researchers analyzed data from 95,405 Medicare claims between 2012 and 2018, using state-level variation in sleeve gastrectomy as the instrumental variable.

At 5 years, sleeve gastrectomy was associated with a lower cumulative frequency of mortality (4.27%; 95% confidence interval, 4.25%-4.30% vs. 5.67%; 95% CI, 5.63%-5.69%]), complications (22.10%; 95% CI, 22.06%-22.13% vs. 29.03%; 95% CI, 28.99%-29.08%), and reintervention (25.23%; 95% CI, 25.19%-25.27% vs. 33.57%; 95% CI, 33.52%-33.63%). At 5 years, surgical revision was more common in the sleeve gastrectomy group (2.91%; 95% CI, 2.90%-2.93% vs. 1.46%; 95% CI, 1.45%-1.47%).

The sleeve gastrectomy group had lower odds of all-cause hospitalization at 1 year (adjusted hazard ratio, 0.83; 95% CI, 0.80-0.86) and 3 years (aHR, 0.94; 95% CI, 0.90-0.98), as well as emergency department use at 1 year (aHR, 0.87; 95% CI, 0.84-0.90) and 3 years (aHR, 0.93; 95% CI, 0.90-0.97). There was no significant difference between the two groups at 5 years with respect to either outcome.

The effort to understand long-term outcomes of these two procedures has been challenging because follow-up is often incomplete, and because reporting isn’t always standardized, according Anita P. Courcoulas, MD, MPH, and Bestoun Ahmed, MD, in an accompanying editorial in JAMA Surgery. They noted that the differences in mortality is a new finding and the difference in surgical revisions confirmed something often seen in clinical practice. “Overall, these novel methods, which creatively balance unmeasured factors, have succeeded in providing important incremental findings about the long-term comparative safety outcomes between bariatric procedures that will be helpful in clinical practice,” the editorial authors wrote.

Let me tell you a story. In 5 billion years the sun will run out of hydrogen, the fuel it is currently burning to power my solar panels amongst other things. At that time, the sun will no longer be able to keep its core contracted and will expand into a fiery, red giant, engulfing earth and obliterating any sign that we ever existed. No buildings. No blog posts. No mausoleums. No stories. Nothing of us will remain.

Well, here for a moment anyway, I’ve gotten you to think about something other than COVID. You’re welcome.

Fascinatingly, the image in your mind’s eye right now of a barren scorched landscape was put there by me. Simply by placing a few words together I have caused new thoughts in your head. You might even share this story with someone else – I would have actually changed your behavior through the power of language. This miraculous phenomenon seems to be unique to us humans; we are the only ones who can create whole worlds in another individual’s head just by making a few sounds. We in medicine have the privilege of experiencing this miracle every day.

Last week, a 97-year-old pale, frail, white man saw me for a basal cell carcinoma on his cheek. While performing a simple electrodesiccation and curettage, I asked if he remembers getting a lot of sunburns when he was young. He certainly remembered one. On a blustery sunny day, he fell asleep for hours on the deck of the USS West Virginia while in the Philippines. As a radio man, he was exhausted from days of conflict and he recalled how warm breezes lulled him asleep. He was so sunburned that for days he forgot how afraid he was of the Japanese.

After listening to his story, I had an image in my mind of palm trees swaying in the tropical winds while hundreds of hulking gray castles sat hidden in the vast surrounding oceans awaiting one of the greatest naval conflicts in history. I got to hear it from surely one of the last remaining people in existence to be able to tell that story. Listening to a patient’s tales is one of the benefits of being a physician. Not only do they help bond us with our patients, but also help lessen our burden of having to make diagnosis after diagnosis and write note after note for hours on end. Somehow performing yet another biopsy that day is made just a bit easier if I’m also learning about what it was like at the Battle of Leyte Gulf.

Encouraging patients to talk more can be risky. No physician, not even allergists, can afford to be waylaid by a retiree with nothing else to do today. But meaningful encounters can not only be a vaccine against burnout, they also lead to better patient adherence and satisfaction. Sometimes, there is simply not time. But often there is a little window during a procedure or when you’re reasonably caught up and don’t expect delays ahead. When patients say that a doctor really listened to me, it is often not their medical history, but their life story they mean. And like every story, they literally transform us, the listener. In a true physical sense, their stories live on in me, and now that I’ve shared this one in writing, also with you for perpetuity. That is at least for the next 5 billion years when it, too, will be swallowed by the sun, leaving only a crispy, smoking rock where we once existed.
