Associations between #body-mass index and #COVID-19 severity in 6·9 million people in England: a prospective, community-based, cohort study

Obesity is a major risk factor for adverse outcomes after infection with SARS-CoV-2. We aimed to examine this association, including interactions with demographic and behavioural characteristics, type 2 diabetes, and other health conditions. MethodsIn this prospective, community-based, cohort study, we used de-identified patient-level data from the QResearch database of general practices in England, UK. We extracted data for patients aged 20 years and older who … Continue reading Associations between #body-mass index and #COVID-19 severity in 6·9 million people in England: a prospective, community-based, cohort study

Long-term body mass index changes in #overweight and #obese adults and the risk of heart failure, #cardiovascular disease and mortality: a cohort study of over 260,000 adults in the UK

Although obesity is a well-recognised risk factor for cardiovascular disease (CVD), the impact of long-term body mass index (BMI) changes in overweight or obese adults, on the risk of heart failure, CVD and mortality has not been quantified. MethodsThis population-based cohort study used routine UK primary care electronic health data linked to secondary care and death-registry records. We identified adults who were overweight or obese, … Continue reading Long-term body mass index changes in #overweight and #obese adults and the risk of heart failure, #cardiovascular disease and mortality: a cohort study of over 260,000 adults in the UK

#Obesity and Responsiveness to #Food Marketing Before and After #Bariatric Surgery

Although food marketing is often accused of increasing population obesity, the relationship between individual responsiveness to marketing and obesity has yet to be established: Are people with obesity more responsive to food marketing and, if so, is it a stable trait or can it be reversed by bariatric surgery? We studied the responses to three common marketing tactics that frame foods and portions as healthier … Continue reading #Obesity and Responsiveness to #Food Marketing Before and After #Bariatric Surgery

The Value of Total #Knee Replacement in Patients With Knee #Osteoarthritis and a Body Mass Index of 40 kg/m2 or Greater A Cost-Effectiveness Analysis

Total knee replacement (TKR) is an effective and cost-effective strategy for treating end-stage knee osteoarthritis. Greater risk for complications among TKR recipients with a body mass index (BMI) of 40 kg/m2 or greater has raised concerns about the value of TKR in this population. Objective: To assess the value of TKR in recipients with a BMI of 40 kg/m2 or greater using a cost-effectiveness analysis. … Continue reading The Value of Total #Knee Replacement in Patients With Knee #Osteoarthritis and a Body Mass Index of 40 kg/m2 or Greater A Cost-Effectiveness Analysis

Association between #obesity with pattern and length of #menstrual cycle: The role of metabolic and hormonal markers

To evaluate in a sample of Chilean adult women, the association between adiposity markers with pattern and length of the menstrual cycle, assessing the influence of metabolic markers and hormones in this relationship. Study design We conducted a cross-sectional study involving 401 premenopausal women belonging to the DERCAM study (Determinants of Breast Cancer Risk) from Santiago, Chile. The menstrual cycle pattern was defined as regular … Continue reading Association between #obesity with pattern and length of #menstrual cycle: The role of metabolic and hormonal markers

Self- Monitoring via Digital Health in #Weight Loss Interventions: A Systematic Review Among Adults with Overweight or #Obesity

Objective: Self- monitoring is a core component of behavioral obesity treatment, but it is unknown how digital health has been used for self- monitoring, what engagement rates are achieved in these interven-tions, and how self- monitoring and weight loss are related. Methods: This systematic review examined digital self- monitoring in behavioral weight loss interventions among adults with overweight or obesity. Six databases (PubMed, Embase, Scopus, … Continue reading Self- Monitoring via Digital Health in #Weight Loss Interventions: A Systematic Review Among Adults with Overweight or #Obesity

Once-Weekly #Semaglutide in Adults with Overweight or #Obesity

Obesity is a global health challenge with few pharmacologic options. Whether adults with obesity can achieve weight loss with once-weekly semaglutide at a dose of 2.4 mg as an adjunct to lifestyle intervention has not been confirmed. METHODS In this double-blind trial, we enrolled 1961 adults with a body-mass index (the weight in kilograms divided by the square of the height in meters) of 30 … Continue reading Once-Weekly #Semaglutide in Adults with Overweight or #Obesity

Effects of two personalized #dietary strategies during a 2‐year intervention in subjects with nonalcoholic #fatty #liver disease: a randomized trial

Background and objectives Nonalcoholic fatty liver disease (NAFLD) management is focused on lifestyle modifications, but long‐term maintenance is a challenge for many individuals. This study aimed to evaluate the long‐term effects of two personalized energy‐restricted dietary strategies on weight loss, metabolic and hepatic outcomes in overweight/obese subjects with NAFLD. Methods Ninety‐eight subjects from the Fatty Liver in Obesity (FLiO) study (NCT03183193) were randomly assigned to … Continue reading Effects of two personalized #dietary strategies during a 2‐year intervention in subjects with nonalcoholic #fatty #liver disease: a randomized trial

#Adipose saturation reduces #lipotoxic systemic inflammation and explains the #obesity paradox

Obesity sometimes seems protective in disease. This obesity paradox is predominantly described in reports from the Western Hemisphere during acute illnesses. Since adipose triglyceride composition corresponds to long-term dietary patterns, we performed a meta-analysis modeling the effect of obesity on severity of acute pancreatitis, in the context of dietary patterns of the countries from which the studies originated. Increased severity was noted in leaner populations … Continue reading #Adipose saturation reduces #lipotoxic systemic inflammation and explains the #obesity paradox

Childhood Daily #Energy Expenditure Does Not Decrease with Market Integration and Is Not Related to #Adiposity in Amazonia

Childhood overweight and obesity (OW/OB) is increasingly centered in low- and middle-income countries (LMICs) as rural populations experience market integration and lifeway change. Most explanatory studies have relied on imprecise estimates of children’s energy expenditure, restricting understanding of the relative effects of changes in diet and energy expenditure on the development of OW/OB in transitioning contexts.. ..Cross-sectional data were collected from “rural” (n = 43) … Continue reading Childhood Daily #Energy Expenditure Does Not Decrease with Market Integration and Is Not Related to #Adiposity in Amazonia

Organ-specific, multimodal, wireless optoelectronics for high-throughput phenotyping of peripheral neural pathways

The vagus nerve supports diverse autonomic functions and behaviors important for health and survival. To understand how specific components of the vagus contribute to behaviors and long-term physiological effects, it is critical to modulate their activity with anatomical specificity in awake, freely behaving conditions using reliable methods. Here, we introduce an organ-specific scalable, multimodal, wireless optoelectronic device for precise and chronic optogenetic manipulations in vivo. … Continue reading Organ-specific, multimodal, wireless optoelectronics for high-throughput phenotyping of peripheral neural pathways

U.S. #Diet Guidelines Sidestep Scientific Advice to Cut #Sugar and #Alcohol

..Evidence suggests that added sugars, particularly those in sweetened beverages, may contribute to obesity and weight gain, which are linked to higher rates of chronic health conditions like heart disease and Type 2 diabetes, the scientific panel noted. More than two-thirds of American adults are overweight or obese; obesity, diabetes and other related conditions also increase the risk of developing severe Covid-19 illness. The scientific … Continue reading U.S. #Diet Guidelines Sidestep Scientific Advice to Cut #Sugar and #Alcohol
