NIH study demonstrates long-term benefits of weight-loss surgery in young people

Adolescents see a greater remission of type 2 diabetes compared to adults

2024-10-30

(Press-News.org) What: Young people with severe obesity who underwent weight-loss surgery at age 19 or younger continued to see sustained weight loss and resolution of common obesity-related comorbidities 10 years later, according to results from a large clinical study funded by the National Institutes of Health (NIH).

Study participants with an average age of 17 underwent gastric bypass or sleeve gastrectomy weight-loss surgery. After 10 years, participants sustained an average of 20% reduction in body mass index (BMI), 55% reduction of type 2 diabetes, 57% reduction of hypertension, and 54% reduction of abnormal cholesterol. Both gastric bypass and sleeve gastrectomy had similar results.

The 55% reduction in type 2 diabetes was much higher than the rates observed in adults after weight-loss surgery (18% at seven years and 12.7% at 12 years) in a recently published NIH-funded study.

Type 2 diabetes tends to progress more rapidly when it occurs in young people, and these findings demonstrate the greater health benefits and durability of bariatric surgery in youth than would be expected in similarly treated adults.

The study, known as Teen Longitudinal Assessment of Bariatric Surgery (Teen LABS), was supported by NIH’s National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) through grants DK072493, DK072493, DK095710 and NIH’s National Center for Research Resources and the National Center for Advancing Translational Sciences Clinical and Translational Science Awards Program grants TR000077 and TR000114.

Data related to these findings are available for request at the NIDDK Central Repository.

Who: Voula Osganian, M.D., a pediatric clinical obesity program director at NIDDK is available to comment on this research.

Sustained remission of diabetes and other obesity-related conditions found a decade after weight loss surgery in adolescence

2024-10-30

Ten years after undergoing bariatric surgery as teens, over half of study participants demonstrated not only sustained weight loss, but also resolution of obesity-related conditions, such as type 2 diabetes, high blood pressure and high cholesterol, according to the report published in the New England Journal of Medicine. “Our study presents impressive outcomes of the longest follow-up of weight loss surgery during adolescence, which validates bariatric surgery as a safe and effective long-term obesity management strategy,” said lead author Justin Ryder, PhD, Vice Chair of Research for the Department ...

Low-level lead poisoning is still pervasive in the US and globally

2024-10-30

Chronic, low-level lead poisoning is a major risk factor for cardiovascular disease in adults and cognitive deficits in children, even at levels previously thought to be safe, according to a new paper by Columbia University Mailman School of Public Health, Simon Fraser University in Canada, and Harvard Medical School, and Boston Children’s Hospital. Low-level lead poisoning is a risk factor for preterm Birth, cognitive deficits and attention deficit–hyperactivity disorder, (ADHD), as well as increased blood pressure and reduced heart rate variability. The findings ...

How researchers can maximize biological insights using animal-tracking devices

2024-10-30

Biologgers allow us to see with unprecedented precision how animals move and behave in the wild. But that's only part of the picture, according to a UC Santa Cruz ecologist renowned for using biologging data to tell the deeper story about the lives of marine mammals in a changing world. In a new opinion piece published on October 30 in Trends in Ecology and Evolution, researchers present a framework intended to underscore the value of biologging data for testing important questions about the natural world. They urge that now is the time to build upon "discovery-based science," where observations are presented ...

Research shows new method helps doctors safely remove dangerous heart infections without surgery

2024-10-30

ROCHESTER, Minn. — Doctors at Mayo Clinic used a new catheter-based approach to draw out resistant pockets of infection that settle in the heart, known as right-sided infective endocarditis, without surgery. Unless treated quickly, the walled-off infections can grow, severely damaging heart valves and potentially affecting other organs as well. In a recent study, over 90% of the participants had their infection cleared, and they had lower in-hospital mortality compared to those whose infections remained. The research is part of a Mayo Clinic-led study ...

Rapid horizontal eye movement can improve stability in people with Parkinson’s

2024-10-30

Rapid side-to-side eye movements can help stabilize posture, avoid falls and maintain balance for people with Parkinson’s disease, just as they can for healthy people. This seemingly counterintuitive conclusion was reached by researchers at São Paulo State University (UNESP) in Brazil and the University of Lille in France in a study supported by FAPESP. An article on the study is published in the journal Biomechanics. Ten individuals diagnosed with Parkinson’s and 11 neurologically healthy individuals participated in the study. All participants were over 60 and were submitted to tests that ...

Study finds COVID-19 pandemic worsened patient safety measures

2024-10-30

PHILADELPHIA (October 30, 2024) – A new study – published in Nursing Research – has found that the COVID-19 pandemic significantly impacted patient safety indicators in U.S. hospitals. The study, from Penn Nursing’s Center for Health Outcomes and Policy Research (CHOPR), examined data from the National Database of Nursing Quality Indicators to assess trends in nursing-sensitive quality indicators from 2019 to 2022. The prevention of these very distressing, uncomfortable conditions is considered to be under the nurse’s purview and directly influenced by nursing care. The investigation found that rates of falls, bloodstream infections from ...

Costs still on the rise for drugs for neurological diseases

2024-10-30

MINNEAPOLIS – The amount of money people pay out-of-pocket for branded drugs to treat neurological diseases like multiple sclerosis (MS), Alzheimer’s, and Parkinson’s disease continues to rise, especially for MS drugs, according to a study published in the October 30, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study found that average out-of-pocket costs for drugs for MS increased by 217% over a nine-year period. Costs have dropped for medications where generic versions have been introduced. “In some ...

Large herbivores have lived in Yellowstone National Park for more than 2,000 years

2024-10-30

Large herbivores like bison or elk have continuously lived in the Yellowstone National Park region for about 2,300 years according to a new analysis of chemicals preserved in lake sediments. John Wendt of Oklahoma State University, U.S., and colleagues present these findings in the open-access journal PLOS ONE on October 30, 2024. The near-extinction of bison in North America in the 19th and 20th centuries was a major ecological catastrophe and little is known about where and how these animals lived before European colonization. In the new study, researchers attempted to determine the dominant large herbivores that lived in the northern Yellowstone National Park ...
