Obesity

Adolescents who undergo metabolic bariatric surgery may require long-term nutrient monitoring and supplementation to prevent nutritional deficiencies, according to investigators.

In a 5-year prospective study, more than a quarter of the participants who underwent vertical sleeve gastrectomy (VSG) developed two or more nutritional deficiencies, reported lead author Stavra A. Xanthakos, MD, of the Cincinnati Children’s Hospital Medical Center, and colleagues.

“Although prevalence of nutritional deficiencies has been estimated largely from adult cohorts, bariatric surgery is an increasingly accepted treatment for severe obesity in youth,” the investigators wrote in Clinical Gastroenterology and Hepatology. “Yet, lower adherence to supplementation and anticipated longer lifespan with altered gastrointestinal physiology may increase risk of adverse nutritional outcomes in these youth.”

Previous research has suggested that teens may be at higher risk for nutritional deficiencies, but these studies were largely retrospective, or when prospective, lacked sufficient long-term follow-up, analysis of comprehensive patient factors, or inclusion of VSG, which is now the predominant technique in the field, the investigators noted.

“Our study is the first to assess comparative nutritional outcomes in adolescents after both VSG and gastric bypass,” they wrote.

The study involved 226 participants aged 13-19 years who underwent either Roux-en-Y gastric bypass (n = 161) or VSG (n = 67) at five tertiary-care centers in the United States during 2007-2012.

Six months after surgery, at 12 months, and on an annual basis thereafter, the investigators gathered clinical data and measured participant serum levels of ferritin; transferrin; albumin; parathyroid hormone; C-reactive protein; and vitamins A, D, B₁, B₁₂, and folate. Analyses also included sex, age, ethnicity, race, household demographics, weight, height, comorbidities, and body mass index (BMI).

The majority of participants were female (75%) and white (72%). At baseline, mean BMI and age were 52.7 kg/m² and 16.5 years, respectively. After 5 years, mean body mass index decreased 23% without a significant difference between procedures.

Generally, nutritional deficiencies occurred earlier and were more common after gastric bypass, although both procedures were ultimately associated with increased risks.

In the gastric bypass group, 59% of participants had two or more nutritional deficiencies at 5 years, and 19% had three more deficiencies, which represented increased rates of fivefold and sixfold, respectively, which the investigators described as “striking.” In the VSG group, 27% of patients had two or more nutritional deficiencies at 5 years; while this fourfold increase was not statistically significant, the investigators suggested that it indicated “a lower, but not negligible, nutritional risk.”

Hypoferritinemia was particularly common in both groups, with rates at year 5 of 71% and 45% among patients who underwent gastric bypass and VSG, respectively.

“Our results now provide critical evidence that VSG does in fact carry significantly lower nutritional risk than Roux-en-Y gastric bypass, but can still worsen iron status,” the investigators wrote.

The investigators also highlighted a nonsignificant increase in the incidence of vitamin B₁₂ deficiency among patients who underwent gastric bypass, with rates increasing from 0.6% at baseline to 11.5% at 5 years.

“Vitamin B₁₂ status likewise worsened disproportionately after [gastric bypass], despite similar trajectories of weight loss after VSG,” the investigators wrote. “This suggests that the differential risk is caused by anatomic and physiological differences between procedures, rather than weight loss alone.”

Beyond surgery type, risk factors for nutritional deficiency included inadequate supplement intake, pregnancy, weight regain, and black race.

“Our findings underscore the importance of long-term nutritional monitoring in adolescents after bariatric surgery and the need to examine impact on health outcomes and quality of life as these youth advance into adulthood, including systematic assessment of anemia and bone health,” the investigators concluded.

The study was funded by the National Institute of Diabetes and Digestive and Kidney Diseases and the National Center for Advancing Translational Sciences of the National Institutes of Health. Dr. Courcoulas reported grant support from Allurion.

Previously I urged you to take a look at a clinical report from the American Academy of Pediatrics that makes an excellent case for the importance of physical activity in the physical and mental health of children. I suggested we should view with some skepticism the authors’ recommendation that we include a quantifiable assessment of physical activity as a vital sign in our EHRs because I found it an unrealistic goal for most busy clinicians.

I also promised to write again and address the authors’ recommendation that we learn how to write an exercise prescription. The authors representing the AAP’s Council on Sports Medicine and Fitness and Section on Obesity observed that many pediatricians feel they lack “the experience or training to guide their patients toward meeting physical activity recommendations.” This is in some part because few if any medical schools or training programs include how to write an exercise prescription in their curricula. Certainly I don’t recall anyone sitting me down and telling me how to prescribe exercise. But, I submit that writing a workable exercise prescription for most patients doesn’t require any special training. However, it does require some common sense and touch of creativity.

Writing any kind of prescription means that you first must know the patient for whom you are writing it. What are his or her capabilities? If the patient has some physical disabilities, you may need to involve a physical therapist or the patient’s specialists in developing the options. But in most cases, common sense will provide you with a place to start.

More important than knowing the patient’s capability is discovering what kind of things the patient and his or her family already find attractive. Convincing people, young or old, they should exercise because it is good for them is more than likely destined to fail. Most of us who enjoy being active have found that it makes us feel better. It is very likely that we developed that affinity by first doing something active that we found enjoyable. Finding that fun gateway into an active lifestyle is where it helps to be creative and to have the patience to suggest multiple options as interest levels fade. For the patient or family who seems to enjoy numerical goals, pedometers and smartwatch fitness trackers can be a hook, but in my experience these gadgets seldom result in a sustainable activity habit.

Does your community have the resources from which the family can choose an activity to fill your prescription? You should know enough about your community’s recreational opportunities and the family’s financial and temporal limitations so that the activity you have prescribed is achievable.

The bottom line is that you must be prepared for failure because most of your thoughtfully crafted prescriptions won’t be taken or even filled. The inertia that we have built into our societies is often too great for families to overcome. But don’t give up. Ask at every visit about activity. Make follow-up visits to discuss the progress or lack of progress to demonstrate that you still consider exercise a valuable and potent piece of the wellness package. And continue to discourage excess screen time.

If you are feeling frustrated by your lack of success writing exercise prescriptions, you may discover that you can be more effective by speaking out at school board and recreation department meetings. Armed with the research included in the AAP’s recent clinical report, you may find powerful allies in the community who share your passion for helping children become more active.

Prescribing liraglutide plus lifestyle therapy for adolescents with obesity resulted in greater weight loss and greater reduction in body mass index, compared with those prescribed lifestyle therapy alone, according to findings from a new study published in The New England Journal of Medicine.

Liraglutide with lifestyle therapy also “compared favorably in terms of [body mass index] reduction,” compared with other pediatric weight-management programs in the United States and with use of orlistat, wrote Aaron S. Kelly, PhD, of the University of Minnesota, Minneapolis, and colleagues. The study abstract was presented during a virtual news conference held by The Endocrine Society. It had been slated for presentation during ENDO 2020, the society’s annual meeting, which was canceled because of the COVID-19 pandemic.

The study included adolescents aged 12-17 years, who had obesity (BMI, ≥30 kg/m²) and had responded poorly to recommendations involving lifestyle therapy only, as judged by the site investigator and documented in the participant’s medical records. The adolescents participated at one of five sites in Belgium, Mexico, Russia, Sweden, and the United States.

In the randomized, controlled, double-blind trial, 125 participants received 3 mg liraglutide, and 126 received placebo for 56 weeks, during which both groups received lifestyle therapy, “defined as counseling about healthy nutrition and physical activity for weight loss,” the authors wrote.

After 12-weeks of run-in, the treatment period lasted 56 weeks, with a follow-up 26 weeks after treatment ended. The liraglutide group retained 80.8% of its participants, and the placebo group, 79.4%.

At week 56, there were no significant differences between the groups in blood pressure, fasting lipids, fasting plasma glucose, or hemoglobin A_1c, the authors noted.

However, in the liraglutide group, 43.3% of participants lost at least 5% of their BMI, compared with 18.7% in the control group. Similarly, 26.1% of those in the liraglutide group had a BMI reduction of at least 10%, compared with 8.1% in the control group.

Participants in the liraglutide group also saw a greater reduction in BMI, compared with those in the placebo group (estimated difference, 4.64 percentage points), and those taking liraglutide lost 9.9 pounds (4.5 kg) more than those receiving placebo – a relative reduction of 5%. The authors noted that a weight loss of 3%-5% “significantly improves some health-related outcomes in adults.”

In addition, the liraglutide group had a BMI standard-deviation score that was 0.22 lower than that in the placebo group (P = .002), but after the participants discontinued with the trial, “a greater increase in the BMI standard-deviation score was observed with liraglutide than with placebo (0.15),” the authors reported.

“Although evidence in children is limited, a change in BMI standard-deviation score of at least 0.20 has been suggested to be clinically meaningful,” they wrote. “Some studies indicate that even temporary weight loss may have long-term benefits, but the extent to which this applies in adolescents and the extent to which long-term adherence to pharmacotherapy can be expected are unknown.”

The researchers added that the reduction in standard-deviation score seen in this study, of 0.22, was a bigger reduction than that seen in lifestyle therapy trials from the U.S. Preventive Services Task Force and from an overview of six Cochrane reviews. Their trial also, however, had a fairly high adherence rate, over 80%.

No notable differences in cardiometabolic markers or in quality of life showed up between the liraglutide and placebo groups. The heterogeneous treatment response in this and past studies suggests the need for future trials to “characterize predictors of treatment response to identify patients who would benefit the most from treatment,” the authors wrote.

About twice as many participants taking liraglutide experienced gastrointestinal adverse events compared with those receiving placebo (64.8% vs. 36.5%, respectively). Those symptoms, a known side effect of this drug type, included nausea, vomiting, and diarrhea and occurred primarily during escalation of the drug dose before then dropping in frequency. Still, the authors note that the high rate of gastrointestinal effects “suggests that this treatment may not be suitable for all patients.”

None of the adolescents receiving the placebo stopped treatment, but 10.4% of those taking liraglutide discontinued. One participant in the liraglutide group died by suicide, but the death was determined to be unrelated to the therapy.

Although the 0.22 reduction in the BMI standard-deviation score was for the intent-to-treat population, the authors calculated that the difference would have been 0.26 “if all participants had adhered to the treatment throughout the trial.”

Novo Nordisk funded the research. Several of the authors reported that they are employees of the company.

The abstract will also be published in a special supplemental issue of the Journal of the Endocrine Society. In addition to a series of news conferences on March 30-31, the society will ost ENDO Online 2020 during June 8-22, which will present programming for clinicians and researchers.

Participants in the liraglutide group also saw a greater reduction in BMI, compared with those in the placebo group (estimated difference, 4.64 percentage points), and those taking liraglutide lost 9.9 pounds (4.5 kg) more than those receiving placebo – a relative reduction of 5%. The authors noted that a weight loss of 3%-5% “significantly improves some health-related outcomes in adults.”

In addition, the liraglutide group had a BMI standard-deviation score that was 0.22 lower than that in the placebo group (P = .002), but after the participants discontinued with the trial, “a greater increase in the BMI standard-deviation score was observed with liraglutide than with placebo (0.15),” the authors reported.

“Although evidence in children is limited, a change in BMI standard-deviation score of at least 0.20 has been suggested to be clinically meaningful,” they wrote. “Some studies indicate that even temporary weight loss may have long-term benefits, but the extent to which this applies in adolescents and the extent to which long-term adherence to pharmacotherapy can be expected are unknown.”

The researchers added that the reduction in standard-deviation score seen in this study, of 0.22, was a bigger reduction than that seen in lifestyle therapy trials from the U.S. Preventive Services Task Force and from an overview of six Cochrane reviews. Their trial also, however, had a fairly high adherence rate, over 80%.

No notable differences in cardiometabolic markers or in quality of life showed up between the liraglutide and placebo groups. The heterogeneous treatment response in this and past studies suggests the need for future trials to “characterize predictors of treatment response to identify patients who would benefit the most from treatment,” the authors wrote.

About twice as many participants taking liraglutide experienced gastrointestinal adverse events compared with those receiving placebo (64.8% vs. 36.5%, respectively). Those symptoms, a known side effect of this drug type, included nausea, vomiting, and diarrhea and occurred primarily during escalation of the drug dose before then dropping in frequency. Still, the authors note that the high rate of gastrointestinal effects “suggests that this treatment may not be suitable for all patients.”

None of the adolescents receiving the placebo stopped treatment, but 10.4% of those taking liraglutide discontinued. One participant in the liraglutide group died by suicide, but the death was determined to be unrelated to the therapy.

Although the 0.22 reduction in the BMI standard-deviation score was for the intent-to-treat population, the authors calculated that the difference would have been 0.26 “if all participants had adhered to the treatment throughout the trial.”

Novo Nordisk funded the research. Several of the authors reported that they are employees of the company.

The abstract will also be published in a special supplemental issue of the Journal of the Endocrine Society. In addition to a series of news conferences on March 30-31, the society will ost ENDO Online 2020 during June 8-22, which will present programming for clinicians and researchers.

Exposure during pregnancy to a specific per- and polyfluoroalkyl substance (PFAS), combined with a low cholesterol level, is linked to a heightened risk of abdominal and whole-body obesity in granddaughters, according to a new analysis of the Child Health and Development Studies, which have been ongoing since the 1960s.

Researchers directly measured levels of N-ethyl-perfluorooctane sulfonamido acetic acid (EtFOSAA) in blood samples from the grandmothers, which had been taken shortly after delivery, and then analyzed measures of obesity and other metabolic factors in their daughters at ages 30 years and 50 years, and their granddaughters at age 20.

PFASs are synthetic compounds commonly used as oil and water repellents; coatings for cookware, carpets, and textiles; and as firefighting foams. The compounds do not break down in the environment or the human body and accumulate over time. They are known to disrupt the endocrine system.

EtFOSAA is a metabolite of a raw material used in the manufacturing of packaging and paper products, and itself gets converted to perfluorooctane sulfonic acid (PFOS), which is extremely stable in the environment and within organisms, leading to bioaccumulation that has the potential to span generations, Barbara A. Cohn, PhD, director of child health and development studies at the Public Health Institute in Berkeley, Calif., said during a virtual press conference held by The Endocrine Society. The study was slated for presentation during ENDO 2020, the society’s annual meeting, which was canceled because of the COVID-19 pandemic.

Abdominal obesity was defined as a waist circumference of more than 34.6 inches (88 cm), and whole-body obesity was defined as a body mass index of more than 30 kg/m². Findings from a previous study drawn from the same cohort showed that exposure to EtFOSAA, combined with high maternal cholesterol levels, was linked to increased risk of breast cancer in daughters.

“I want to emphasize that we don’t understand the mechanism, but we do know that this finding [from the current study], if it is confirmed, has implications for the current epidemic of obesity. Exposure to these compounds is very widespread, [having] started in the 1940s and 50s, and is consistent with the timing of the obesity epidemic,” said Dr. Cohn, during the virtual press conference.

Robert Sargis, MD, professor of endocrinology, diabetes, and metabolism at the University of Illinois at Chicago, said the mechanistic connection could be complex. “It’s a combination of the possibility that the chemicals themselves are passed down either through breast milk or across the placenta, or that the biological impact is somehow coded epigenetically, and then that epigenetic code is somehow passed on to subsequent generations,” he said in an interview. He was not associated with the research.

Dr. Cohn said her team is investigating both of those possibilities through analysis of the existing blood samples. “There are implications for PFAS clean-up if [these findings are] confirmed, and there’s an opportunity for setting up precautions for pregnant women on how they can try to avoid this contamination to [offset] a rekindling of this generational effect 60 years down the road,” Dr. Cohn added.

Daughters of the original participants (now grandmothers) were measured at an average age of 50, and the granddaughters, at an average of 20 (219 dyads, 657 women in total). Daughters also reported their weight at age 30, which was close to the mean age at which they had given birth. This allowed the researchers to control for obesity present during gestation of the granddaughters.

The researchers analyzed EtFOSAA, PFOS, and cholesterol levels from archived blood samples taken from grandmothers within 3 days of delivery. There was an association between EtFOSAA and self-reported obesity at age 30 in daughters, as well as measured abdominal, whole-body obesity, and blood pressure at age 20 in granddaughters, and all were modified by low cholesterol levels (25% interquartile) in grandmothers (P < .05).

In granddaughters, the combined risk of abdominal and whole-body obesity was 2.3-fold higher in those whose grandmothers were in the top 25% of EtFOSAA exposure, compared with those whose grandmothers were in the lowest 25% (95% confidence interval, 1.1-4.8). Those associations remained after adjustments for race, being overweight in early pregnancy (BMI, >25 kg/m²), and serum PFOS levels.

Although the weight of daughters did not affect the association between the granddaughters’ risk for obesity risk and EtFOSAA levels in grandmothers, it did predict high metabolic risk in granddaughters. That suggests that the burden may be building over generations. “Independently, their mothers themselves are heavier and fatter, and that heaviness of the mother is also a source of increasing body size for the granddaughter. We have a multiplying, very ugly situation that may be helping us to understand this really quick rise of obesity,” said Dr. Cohn.

She also emphasized that PFAS may not be the only culprit in fueling obesity. “Most of us believe that there is sufficient data in the animal studies and, now, growing data in human studies, to suggest that these obesogens exist and are contributing to the health problems that are going to be following the obesity epidemic in young people now.”

Dr. Cohn noted that the study is limited by its lack of a control group.

The California Breast Research Foundation, the National Institutes of Health, and the State of California funded the study. Dr. Cohn and Dr. Sargis reported no relevant financial disclosures.

The study abstract will be published in the Journal of the Endocrine Society. In addition to a series of news conferences held on March 30-31, the society will host ENDO Online 2020 during June 8-22 with programming for clinicians and researchers.

People with diabetes may benefit less from bariatric surgery, compared with those without the disease, according to a retrospective review of patients receiving both sleeve gastrectomy and gastric bypass.

The difference was particularly pronounced and persistent for patients who had gastric bypass, Yingying Luo, MD, said during a virtual news conference held by the Endocrine Society. The study was slated for presentation during ENDO 2020, the society’s annual meeting, which was canceled because of the COVID-19 pandemic.

“Our findings demonstrated that having bariatric surgery before developing diabetes may result in greater weight loss from the surgery, especially within the first 3 years after surgery and in patients undergoing gastric bypass surgery,” said Dr. Luo.

More than a third of U.S. adults have obesity, and more than half the population is overweight or has obesity, said Dr. Luo, citing data from the Centers for Disease Control and Prevention.

Bariatric surgery not only reduces body weight, but also “can lead to remission of many metabolic disorders, including diabetes, hypertension, and dyslipidemia,” said Dr. Luo, a visiting scholar at the University of Michigan’s division of metabolism, endocrinology, and diabetes. However, until now, it has not been known how diabetes interacts with bariatric surgery to affect weight loss outcomes.

To address that question, Dr. Luo and her colleagues looked at patients in the Michigan Bariatric Surgery Cohort who were at least 18 years old and had a body mass index (BMI) of more than 40 kg/m², or of more than 35 kg/m² with comorbidities.

The researchers followed 380 patients who received gastric bypass and 334 who received sleeve gastrectomy for at least 5 years. Over time, sleeve gastrectomy became the predominant type of surgery conducted, noted Dr. Luo.

At baseline, and yearly for 5 years thereafter, the researchers recorded participants’ BMI as well as their lipid levels and other laboratory values. Medication use was also tracked. Patients with a diagnosis of diabetes also had their hemoglobin A_1c levels recorded at each visit.

Overall, patients in the sleeve gastrectomy group were more overweight, and those in the gastric bypass group had higher HbA_1c and total cholesterol levels. The mean baseline weight for the sleeve gastrectomy recipients was 141.5 kg, compared with 133.5 kg for those receiving gastric bypass (BMI, 49.9 vs. 47.3 kg/m², respectively; P < .01 for both measures). Mean HbA_1c was 6.5% for the gastric bypass group, compared with 6.3% for the sleeve gastrectomy group (P = .03).

At baseline, 149 (39.2%) of the gastric bypass patients had diabetes, compared with 108 (32.3%) of the sleeve gastrectomy patients, but the difference was not statistically significant.

About two-thirds of the full cohort were tracked for at least 5 years, which is still considered “a good follow-up rate in a real-world study,” said Dr. Luo.

Total weight loss was defined as the difference between initial weight and postoperative weight at a given point in time. Excess weight was the difference between initial weight and an individual’s ideal weight, that is, what their weight would have been if they had a BMI of 25 kg/m².

“The probability of achieving a BMI of less than 30 kg/m² or excess weight loss of 50% or more was higher in patients who did not have diabetes diagnosis at baseline. We found that the presence of diabetes at baseline substantially impacted the probability of achieving both indicators,” said Dr. Luo. “Individuals without diabetes had a 1.5 times higher chance of achieving a BMI of under 30 kg/m², and … [they also] had a 1.6 times higher chance of achieving excess body weight loss of 50%, or more.” Both of those differences were statistically significant on univariate analysis (P = .0249 and .0021, respectively).

The researchers conducted further statistical analysis – adjusted for age, gender, surgery type, and baseline weight – to examine whether diabetes still predicted future weight loss after bariatric surgery. After those adjustments, they still found that “the presence of diabetes before surgery is an indicator of future weight loss outcomes,” said Dr. Luo.

The differences in outcomes for those with and without diabetes tended to diminish over time in looking at the cohort as a whole. However, greater BMI reduction for those without diabetes persisted for the full 5 years of follow-up for the gastric bypass recipients. Those trends held when the researchers looked at the proportion of patients whose BMI dropped to below 30 kg/m², and those who achieved excess weight loss of more than 50%.

Dr. Luo acknowledged that an ideal study would track patients for longer than 5 years and that studies involving more patients would also be useful. Still, she said, “our study opens the door for further research to understand why diabetes diminishes the weight loss effect of bariatric surgery.”

The research will be published in a special supplemental issue of the Journal of the Endocrine Society. In addition to a series of news conferences on March 30-31, the society will host ENDO Online 2020 during June 8-22, which will present programming for clinicians and researchers.

Dr. Luo reported no outside sources of funding and no conflicts of interest.

We found that the presence of diabetes at baseline substantially impacted the probability of achieving both indicators,” said Dr. Luo. “Individuals without diabetes had a 1.5 times higher chance of achieving a BMI of under 30 kg/m², and … [they also] had a 1.6 times higher chance of achieving excess body weight loss of 50%, or more.” Both of those differences were statistically significant on univariate analysis (P = .0249 and .0021, respectively).

The researchers conducted further statistical analysis – adjusted for age, gender, surgery type, and baseline weight – to examine whether diabetes still predicted future weight loss after bariatric surgery. After those adjustments, they still found that “the presence of diabetes before surgery is an indicator of future weight loss outcomes,” said Dr. Luo.

The differences in outcomes for those with and without diabetes tended to diminish over time in looking at the cohort as a whole. However, greater BMI reduction for those without diabetes persisted for the full 5 years of follow-up for the gastric bypass recipients. Those trends held when the researchers looked at the proportion of patients whose BMI dropped to below 30 kg/m², and those who achieved excess weight loss of more than 50%.

Dr. Luo acknowledged that an ideal study would track patients for longer than 5 years and that studies involving more patients would also be useful. Still, she said, “our study opens the door for further research to understand why diabetes diminishes the weight loss effect of bariatric surgery.”

The research will be published in a special supplemental issue of the Journal of the Endocrine Society. In addition to a series of news conferences on March 30-31, the society will host ENDO Online 2020 during June 8-22, which will present programming for clinicians and researchers.

Dr. Luo reported no outside sources of funding and no conflicts of interest.

If you haven’t already found out that activity is a critical component in the physical and mental health of your patients, or if you’re trying to convince an influential person or group it deserves their attention and investment, I suggest you chase down this clinical report from the American Academy of Pediatrics. Representing the AAP’s Council on Sports Medicine and Fitness and Section on Obesity, the authors quite thoroughly make the case that anyone concerned about the health of this nation and its children should make promotion of physical activity a top priority.

I suspect that, like many of the position papers that come from the AAP, this clinical report is another example of preaching to the choir. However, I understand that the academy also hopes to convince a broader audience of nonphysician decision makers by laying out all of the evidence they can muster.

With their voluminous supporting evidence on the table, the authors move on to getting those of us in clinical practice to make our approach to this more systematic – including the addition of a Physical Activity Vital Sign (PAVS) in our patients’ health records. And here is where the authors begin to drift into the hazy dream world of unreality. They admit that “pediatricians will need efficient workflows to incorporate physical activity assessment, counseling and referral in the clinical visit.” Although there is no pediatrician more convinced of the importance of physical activity, I would find it very difficult to include a detailed assessment of my patients’ daily activity in their charts in the manner that the council members envision. Clunky EHRs, limited support staff, and a crowd of advocates already clamoring for my attention on their favorite health issue (nutrition, gun safety, parental depression, dental health to name just a few) all make creating an “efficient workflow” difficult on a good day and impossible on many days.

But, as I have said, I am a strong advocate of physical activity. So here’s a more nuanced suggestion based on a combination of my practical experience and the council’s recommendations.

If you provide good continuity of care to the families in your practice and have been asking good “getting to know you” questions at each visit, you probably already know which of your patients are sufficiently active. You don’t need to ask them how many hours a week they are doing something active. You should be able to just check a box that says “active.”

For patients that you haven’t seen before or suspect are too sedentary from looking at their biometrics and listening to their complaints you need only ask “What do you and your family like to do for fun?” The simple follow-up question of how many hours are spent watching TV, looking at smart phones or tablets, and playing video games in each day completes the survey. You don’t need to chart the depressing details because, as we know, relying on patient or parental recall is unlikely to provide the actual numbers. Just simply check the box that says “not active enough.” What you do with this crude assessment activity is another story and will be the topic for the next Letters from Maine.

This clinical report from the AAP is an excellent and exhaustive discussion of the importance of physical activity, but I hope that it doesn’t spark further cluttering of our already challenged EHR systems. Most of us don’t have the time to be data collectors and quantifiers. Let’s leave that to the clinical researchers. We already know activity is important and that most of our sedentary families aren’t going to be impressed by more science. Our challenge is to get them moving.

For patients with nonalcoholic steatohepatitis (NASH) with cirrhosis and portal hypertension, belapectin therapy was safe but did not significantly improve fibrosis or hepatic venous pressure gradient, compared with placebo, according to the results of a multicenter phase 2b study.

After 52 weeks of infusions, the change in hepatic venous pressure gradient did not significantly differ between the 2-mg/kg group (–0.28 mm Hg) and the placebo group (0.10 mm Hg) or between the 8-mg/kg group (–0.25 mm Hg) and the placebo group (P = .1 for both comparisons). Belapectin also did not significantly improve fibrosis, nonalcoholic fatty liver disease activity score, or the frequency of various complications of cirrhosis. “However, in a subgroup analysis of patients without esophageal varices, 2 mg/kg belapectin did reduce hepatic venous pressure gradient and development of varices,” wrote Naga Chalasani, MD, of Indiana University in Indianapolis and his associates. The findings were published in Gastroenterology.

NASH leads to portal hypertension, variceal bleeding, ascites with bacterial peritonitis, hepatic encephalopathy, and liver-related death and is a leading reason for liver transplantation among women and men. Galectin-3, which is primarily secreted by macrophages, is elevated in patients with NASH and has been linked to the pathophysiology of liver fibrosis in mice. Belapectin (GR-MD-02), a complex carbohydrate that targets and disrupts galectin-3, has been found to reduce liver fibrosis and portal hypertension in rats and was safe and well tolerated in phase 1 studies.

For this double-blind trial, the researchers randomly assigned 162 patients with NASH, cirrhosis, and portal hypertension (hepatic venous pressure gradient at least 6 mm Hg) to receive biweekly infusions of belapectin 2 mg/kg (54 patients), belapectin 8 mg/kg (54 patients), or placebo (54 patients). Patients were treated for 52 weeks. The primary endpoint was change from baseline in hepatic venous pressure gradient.

In a post-hoc analysis of the 81 patients who had no esophageal varices at baseline, 2 mg/kg belapectin was associated with an average 1.61-mm Hg reduction in hepatic venous pressure gradient from baseline (P = .02) and with a reduction in the development of new varices (P = .03).These effects did not extend to subgroups of patients with varices at baseline, clinically significant portal hypertension, or mild portal hypertension. Moreover, 2 mg/kg belapectin did not improve fibrosis, and the higher dose of belapectin (8 mg/kg) met neither the primary endpoint nor the secondary endpoints in the overall cohort or in subgroup analyses. In the subgroup with no varices at baseline, Galectin Technologies is proceeding to initiating a phase 3 clinical trial.

“Interestingly and somewhat unexpectedly, belapectin was associated with an improvement in hepatocyte ballooning,” which “is considered fundamental to the pathogenesis of disease progression in nonalcoholic steatohepatitis,” the researchers wrote. “The significance of such improvement in hepatocyte ballooning in the absence of improvement of other histological components, especially inflammation, is unknown.”

Galectin Therapeutics provided funding. Dr. Chalasani disclosed grant support from Galectin Therapeutics and relevant consulting relationships with NuSirt, AbbVie, Afimmune (DS Biopharma), and several other pharmaceutical companies. Sixteen coinvestigators also disclosed relationships with pharmaceutical companies, of whom eight disclosed consulting relationships, received research funding, or were employed by Galectin.

Bariatric surgery was associated with a significant reduction in the risk of colorectal cancer among obese adults in a retrospective study of more than 1 million individuals.

Although some studies have suggested that bariatric surgery may reduce the risk of obesity-associated cancers, such as colorectal cancer, other studies have shown an increased colorectal cancer risk after surgery, according to Laurent Bailly, MD, of Université Côte d’Azur in Nice, France, and colleagues.

In a study published in JAMA Surgery, Dr. Bailly and colleagues compared the incidence of colorectal cancer in obese patients who underwent bariatric surgery with the incidence in obese patients who did not have surgery and the incidence in the general population.

Using the French National Health Insurance Information System database, the researchers identified 1,045,348 obese adults aged 50-75 years who had no colorectal cancer at baseline. Of these patients, 74,131 underwent bariatric surgery and 971,217 did not. The mean age was 57.3 years in the surgery group and 63.4 years in the nonsurgery group.

The mean follow-up period was 6.2 years for patients who underwent adjustable gastric banding, 5.5 years for those with sleeve gastrectomy, 5.7 years for those who underwent gastric bypass, and 5.3 years for the nonsurgery group.
 

Results

Overall, the colorectal cancer rate was 0.6% in the surgery group and 1.3% in the nonsurgery group (P < .001).

The researchers calculated standardized incidence ratios (SIRs) to compare the risk of colorectal cancer in the study population with the risk among the French general population; in other words, the number of observed colorectal cancer cases divided by the number of expected cases.

In the surgery group, 423 cases of colorectal cancer were observed and 428 cases were expected, which leads to an SIR of 1.0. In the nonsurgery group, 12,629 cases were observed and 9,417 cases were expected, leading to an SIR of 1.34.

These results suggest patients in the nonsurgery group had a 34% higher risk of colorectal cancer compared with the general population, whereas the risk in the surgery group was similar to that in the general population.

Patients who underwent either gastric bypass or sleeve gastrectomy had fewer new colorectal cancer diagnoses (0.5% for both) compared with patients who had adjustable gastric banding (0.7%).

The researchers noted that this study was limited by several factors, including the retrospective, observational design and potential selection bias among surgery patients. However, the results were strengthened by the large study population and long-term follow-up.
 

Putting results into context

The authors of an invited commentary noted that this study is supported by results from a retrospective, U.S.-based study, which indicated that bariatric surgery has a “protective effect” against colorectal cancer (Ann Surg. 2019 Jan;269[1]:95-101).

However, these results conflict with other retrospective studies. A study of Nordic patients suggested that bariatric surgery is associated with an increased risk of colon cancer but perhaps not rectal cancer (Int J Cancer. 2019. doi: 10.1002/ijc.32770).

And a study of English patients showed an increased risk of colorectal cancer in patients who underwent gastric bypass but not in those who underwent gastric banding or sleeve gastrectomy (Br J Surg. 2018;105(12):1650-7).

These conflicting results “imply that the jury is still out on whether bariatric surgery increases or decreases” the risk of colorectal cancer, the commentators wrote. They added that future studies “must account for differences in study population (i.e., race/ethnicity and national origin), mechanistic variation in bariatric surgical type, and length of follow-up, while also distinguishing between rectal and colon cancer before the case is settled.”

This study had no outside sponsorship, and the researchers and commentators had no financial conflicts to disclose.

However, these results conflict with other retrospective studies. A study of Nordic patients suggested that bariatric surgery is associated with an increased risk of colon cancer but perhaps not rectal cancer (Int J Cancer. 2019. doi: 10.1002/ijc.32770).

And a study of English patients showed an increased risk of colorectal cancer in patients who underwent gastric bypass but not in those who underwent gastric banding or sleeve gastrectomy (Br J Surg. 2018;105(12):1650-7).

These conflicting results “imply that the jury is still out on whether bariatric surgery increases or decreases” the risk of colorectal cancer, the commentators wrote. They added that future studies “must account for differences in study population (i.e., race/ethnicity and national origin), mechanistic variation in bariatric surgical type, and length of follow-up, while also distinguishing between rectal and colon cancer before the case is settled.”

This study had no outside sponsorship, and the researchers and commentators had no financial conflicts to disclose.

I don’t know how successful you have been at getting your adolescent patients to follow your suggestions, but I would guess that my batting average was in the low 100s. Even when I try stepping off my soapbox to involve the patient in a nonjudgmental dialogue, my successes pale in comparison to my failures.

Just looking at our national statistics for obesity, it’s pretty obvious that we are all doing a pretty rotten job of modifying our patients behaviors. You could point to a few encouraging numbers but they are few and far between. You could claim correctly that by the time a child reaches preschool, the die is already cast, throw up your arms, and not even raise the subject of diet with your overweight teenage patients.

A recent article in the journal Appetite hints at a group of strategies for molding patient behavior that so far have gotten very little attention from physicians (“Do perceived norms of social media users eating habits and preferences predict our own food consumption and BMI?” Appetite. 2020 Jan 18. doi: 10.1016/j.appet.2020.104611). Researchers at the department of psychology at Ashton University in Birmingham, England, surveyed more than 350 college-age students asking them about the dietary preference of their Facebook contacts and their own dietary habits. What the investigators found was that respondents who perceived their peers ate a healthy diet ate a healthier diet. Conversely, if the respondents thought their social media contacts ate junk food, they reported eating more of an unhealthy diet themselves.

In other words, it appears that, through social media, we have the potential to influence the eating habits of our patients’ peers. Before we get too excited, it should be pointed out that this study from England wasn’t of a long enough duration to demonstrate an effect on body mass index. And another study of 176 children recently published in Pediatrics found that while influencer marketing of unhealthy foods increased children’s immediate food intake, the equivalent marketing of healthy foods had no effect (“Social influencer marketing and children’s food intake: A randomized trial.” Pediatrics. 2019 Apr 1. doi: 10.1542/peds.2018-2554).

Not being terribly aware of the whos, whats, and wheres of influencers, I did a little bit of Internet searching at the Influencer Marketing hub and learned that influencers comes in all shapes and sizes, from “nanoinfluencers” who have acknowledged expertise and a very small Internet following numbering as few as a hundred to “megainfluencers” who have more than a million followers and might charge large entities a million dollars for a single post. The influencer’s content could appear as a blog, a YouTube video, a podcast, or simply a social media post.

The field of influencer marketing is new and growing exponentially. We would be wise as a group and as individuals to learn as much as we can about how we can use influencers to promote healthy behaviors. This initiative could come in the form of an office dedicated to Influencer Marketing created by the American Academy of Pediatrics. That group could search for megainfluencers who might be funded by the academy. But it also could develop a handbook for individual practitioners and groups to help them identify nano- and micro- (1,000-40,000 followers) influencers in their own practices.

You probably don’t ask your patients about their social media habits other than to caution them about time management. Maybe it’s time to dig a little deeper. You may find that you have a potent influencer hidden in your practice. She or he might just be willing to spread a good word or two for you.

It’s hard to find good news these days, but I thought I had stumbled on a nice feel-good story in the Portland Press Herald. It turns out a group of students at the King Middle School in Portland, Maine, has formed a team of “compost guardians,” who by coaxing their fellow students into sorting their uneaten lunch food into five reusable or recyclable categories have reduced the cafeteria’s daily waste production from 12 40-gallon trash bags to 2. (“Each year, Maine’s K-12 schools waste about 7 million pounds of food,” by Rachel Ohm, Portland Press Herald, Feb. 2, 2020). That seems like a heroic accomplishment and good news by any standard.

However, as I read on in the newspaper article it became clear that these students’ efforts represent a tiny speck of light in the middle of a very dark tunnel. In developing their system, the students learned that 34% of the food was not being consumed, which is part of the 30%-40% of food wasted across the country. In Maine, this represents about 7 million pounds of food wasted annually. Not surprisingly, the students found that 60% of the fruit and 28% of the vegetables go uneaten.

But current federal guidelines dictate that students must take a vegetable and a fruit on their trays. While well-intentioned, this is a mandate destined to generate waste.

King Middle School and many other schools around the country offer a program that is not in the federal guidelines: a “share table” where students can place unwanted (but safe to eat) food, and from which other students may serve themselves freely. On the surface, this may seem like a good idea because it legitimizes what children have been doing for years on their own. This shared food should consist of “healthy choices” because it is cafeteria fare dictated by the United States Department of Agriculture. But you know as well as I do that a child can become obese overeating a diet that in moderate amounts would be considered healthy. I suspect that many, if not most, students taking food from the share table don’t need any extra calories.

The USDA recently announced that it will be rolling out reforms for school and summer meal programs (USDA Release # USDA 0129.20). One of the goals of these reforms is to reduce food wastage by giving schools more flexibility in creating menus and offering more à la carte options. In the wake this rollout, there has been some concern voiced that schools will begin to offer less nutritional options. Unfortunately, this concern may be true in some districts, but it is pretty clear that the current guidelines are a significant contributor to food wastage without offering much of an upside. It may be time to lessen the record-keeping burden on local food services, and allow them some leeway in creating more appealing options while taking advantage of local food sources.

With or without the new guidelines, we are asking public schools to cater to multiple cohorts of students whose parents have put them on the bus in the morning as mismanaged picky eaters.

What would have worked at home could work at school. That strategy is to offer a child a balanced diet presented in an appealing manner in a pleasant setting. Also it is not allowing any sweetened beverages or milk in excess. Children may grumble temporarily but if the strategy is applied consistently, they will take it from there. That doesn’t mean that the children have to put the food on their trays if they don’t want it. But they shouldn’t be offered a second run through the cafeteria line or a chance to pick from the share table. Sadly, the success of this strategy relies on two shaky premises: That parents will begin to apply it at home and that school lunch programs will offer only healthy choices.

The bottom line is that schools can’t be expected to cure picky eaters who were enabled at home. On the other hand, it is not unreasonable to ask schools to play a role in curbing the national scourge of food wastage.
