Staying informed on the latest in cachexia, sarcopenia, and wasting disorders research is essential yet challenging. The SCWD Digest offers concise updates and expert insights into significant studies and developments. We highlight and link directly to leading research, making it easier for healthcare professionals to access and apply groundbreaking findings. Our goal: empower the medical community to advance patient care worldwide efficiently.
BACKGROUND
The health consequences of being underweight are less well-studied than obesity. We aimed to examine the association between body mass index (BMI) and mortality from a wide range of diseases across the full BMI spectrum, with particular focus on how...
BACKGROUND
Resistance training (RT) is an established intervention for increasing lean body mass (LBM), individual hypertrophic responses exhibit significant heterogeneity, largely influenced by genetic factors. This genome-wide association study (GWAS) aimed to identify novel genetic variants associated with changes in lean...
BACKGROUND
Older adults with osteosarcopenia, defined as the coexistence of osteopenia/osteoporosis and sarcopenia, have been associated with an increased risk of fractures compared with those with normal bone mineral density (BMD) and without sarcopenia. However, the conventional definition of osteosarcopenia has...
BACKGROUND/PURPOSE OF THE STUDY
The Asian Working Group for Sarcopenia (AWGS) updated its criteria in 2025, adding a body mass index (BMI)-adjusted muscle index (ASM/BMI) to the conventional skeletal muscle index (SMI). We aimed to compare the prognostic performances of the...
BACKGROUND
Highly effective anti-obesity medications (AOMs) induce substantial weight loss and have renewed debate on appropriate treatment targets. Weight loss comprises reductions in fat mass (FM) and fat-free mass (FFM), with skeletal muscle (SM) as the major component of FFM. Clinical...
Cancer cachexia is a wasting condition characterized by muscle loss and reduced quality of life in cancer patients. Although biological sex differences in the progression of cancer cachexia have been increasingly recognized, their role during chemotherapy-treated cancer cachexia remains largely...
BACKGROUND
Dietary and pharmacologic weight loss can reduce skeletal muscle. Whether calcium beta-hydroxy-beta-methylbutyrate (CaHMB)-enriched supplementation preserves muscle while promoting fat loss in adults with obesity remains uncertain. We evaluated a CaHMB-enriched nutritional supplement during energy restriction.
METHODS
In this randomized, double-blind, controlled trial,...
BACKGROUND
The association of fat-to-lean mass ratio (FLR) with mortality remains unclear in older adults. This study aimed to investigate the sex-specific associations of total and regional FLR with mortality in older Chinese adults.
METHODS
This analysis included 2000 men (mean age: 72.4 ± 5.0 years)...
OBJECTIVE
To examine whether sarcopenic obesity (SO) is associated with incident type 2 diabetes (T2D) beyond obesity or sarcopenia alone and whether associations differ by sex, age, and transitions in body composition phenotypes over time.
RESEARCH DESIGN AND METHODS
We studied 479,607 diabetes-free...
BACKGROUND
Dnajb5, a member of the heat shock protein family, has not been previously reported to play a role in muscle differentiation. We identify Dnajb5 as a negative regulator of myogenesis via mammalian target of rapamycin (mTOR) and histone deacetylase 4...
Sarcopenia is the age-related loss of muscle strength and size that leads to mobility limitations and loss of independence in older adults. The underlying cellular mechanisms remain unclear, and treatments are limited. As the critical interface between the nervous system...
BACKGROUND
Venous thromboembolism (VTE) is a major acute cardiovascular condition with high mortality, affecting nearly 10 million individuals worldwide each year. Identifying novel and modifiable risk factors is crucial for advancing prevention strategies. Intramuscular fat infiltration (IMFI), a modifiable condition linked...
BACKGROUND
The serine/threonine kinase AKT is a key regulator of glucose and energy metabolism. Prevailing dogma suggests that AKT is an obligate intermediate for glucose uptake in all metabolic tissues and that impaired AKT signalling is a major molecular driver of...
