Vitamin #D Insufficiency Reduces Grip Strength, Grip Endurance and Increases Frailty in Aged C57Bl/6J Mice

Low 25-OH serum vitamin D (VitD) is pervasive in older adults and linked to functional decline and progression of frailty. We have previously shown that chronic VitD insufficiency in “middle-aged” mice results in impaired anaerobic exercise capacity, decreased lean mass, and increased adiposity. Here, we examine if VitD insufficiency results in similar deficits and greater …

Nocturnal #Arrhythmias and Heart‐Rate Swings in Patients With Obstructive Sleep #Apnea Syndrome Treated With Beta Blockers

The higher cardiovascular variability and the increased prevalence of arrhythmias in patients with obstructive sleep apneas may contribute to their higher rate of fatal events during sleep. In this regard, the use of beta blockers (BB) is debated because they may induce bradyarrhythmias and alter the pattern of heart rate changes induced by apneas. Thus, …

Effect of Vitamin #D and ω-3 #Fatty Acid Supplementation on Risk of Age-Related #Macular Degeneration An Ancillary Study of the VITAL Randomized Clinical Trial

Observational studies suggest that higher intake or blood levels of vitamin D and marine ω-3 fatty acids may be associated with lower risks of age-related macular degeneration (AMD). However, evidence from randomized trials is limited.. ..In total, 25 871 participants with a mean (SD) age of 67.1 (7.0) years were included in the trial. Of them, …

Air #pollution as a determinant of food delivery and related #plastic waste

Plastic waste is a growing environmental concern. The food delivery industry is criticized for its environmental impact, especially its current use of plastic packaging. At the same time, the environment impacts the industry. We show that air pollution is a behavioural driver of food delivery consumption in the urban developing world. Our hypothesis is that …

Inadequate #Physical Activity and #Sedentary Behavior Are Independent Predictors of Nonalcoholic Fatty #Liver Disease

In general, physical activity (PA) and nonalcoholic fatty liver disease (NAFLD) have an inverse association. However, studies assessing the impact of the widely accepted Physical Activity Guidelines for Americans (PA Guidelines) on NAFLD are lacking. We performed a serial, cross‐sectional analysis among adults by using the 2007‐2016 US National Health and Nutrition Examination Survey. NAFLD …
