Intramuscular Fat as a Biomarker of Muscle Health: Strengths, Limitations and Open Challenges

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 5, October 2026.
ABSTRACT Intramuscular fat (IMF), also known as myosteatosis, refers to the accumulation of lipids within and around skeletal muscle fibres. Excess IMF is increasingly recognised as a sign of poor muscle quality, linked to reductions in strength, power and mobility, and associated with adverse outcomes in metabolic disease, osteoarthritis ...

Chemotherapy‐Induced Skeletal Muscle Dysfunction and Cognitive Impairment: A Muscle‐Brain Mechanistic Framework With Implications for Exercise Oncology

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 5, October 2026.
ABSTRACT Chemotherapy commonly induces skeletal muscle dysfunction and cognitive impairment, complications that reduce treatment tolerance and quality of life. Skeletal muscle mass frequently declines during chemotherapy, with cohort studies reporting losses of 3%–10% across treatment courses, while chemotherapy‐induced cognitive impairment affects up ...

Physical Performance Moderates the Association Between Age and Executive Function in Older Adults at Elevated Risk of Dementia: Cross‐Sectional Analysis From the CITA GO‐ON Trial

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 5, October 2026.
ABSTRACT Background Preservation of executive function is vital for independence and dementia prevention, yet the physical performance levels at which age‐related executive vulnerability becomes detectable remain uncertain. This study examined whether gait speed, handgrip strength and leg muscle power influence the relationship between age and ...

Mapping Fatty Acid Composition in the Human Knee: Short‐Term Repeatability at 3T

open access: yesJournal of Magnetic Resonance Imaging, Volume 64, Issue 4, Page 1066-1076, October 2026.
ABSTRACT Background Alterations in periarticular lipid composition are implicated in musculoskeletal diseases, yet short‐term reliability of MRI‐based triglyceride composition mapping in the knee is not fully established. Purpose To evaluate 1‐week repeatability of proton‐density fat fraction (PDFF) and triglyceride fatty‐acid composition—saturated ...
