Validity and agreement of bioelectrical impedance equations against dual energy X‐ray absorptiometry for muscle mass assessment in patients on hemodialysis: A cross‐sectional study

Nutrition in Clinical Practice, EarlyView.
Abstract Background Low muscle mass is common in patients on hemodialysis (HD), and bioelectrical impedance analysis (BIA) predictive equations have been proposed as an alternative for estimating muscle mass. This study aimed to analyze the validity and agreement of different BIA‐based prediction equations against dual energy X‐ray absorptiometry (DXA)

Disentangling the effect of brain insulin resistance on brain health (BIR‐BrainHealth): Rationale and study protocol

Diabetic Medicine, EarlyView.
Abstract Aims Insulin signalling in the brain is crucial for systemic metabolic regulation and cognitive function. In some individuals, these effects are reduced, a phenomenon referred to as brain insulin resistance (BIR). This condition may contribute to the elevated risk of cognitive decline and dementia in diabetes, yet its prevalence, mechanisms ...

Metabolic pattern across energy imbalance: An exploratory metabolomics study of female body weight extremes including anorexia nervosa and athletes

Experimental Physiology, EarlyView.
Abstract In anorexia nervosa (AN), prolonged metabolic adaptation to severe energy deficiency can impair treatment efficacy. Similarly, low energy availability poses a recognized risk to athletes, potentially compromising health and performance. This cross‐sectional study aimed to characterize the plasma metabolic pattern of females with varying ...
