Nutritional intake adequacy, muscle mass, strength, and sarcopenia in adults on hemodialysis in Panama: A descriptive cross-sectional study.

New evidencemalnutritionepidemiologyhealth servicesbiomarker
Clinical takeawayConsider routine nutritional and muscle health assessment using calf circumference, handgrip strength, and phase angle in hemodialysis patients to identify sarcopenia and guide interventions, particularly in resource-limited settings like Panama.
What it found89.5% of hemodialysis patients consumed <80% of energy requirements (median 17.0 kcal/kg/day) and 79.0% <80% of protein (0.8 g/kg/day); sarcopenia prevalence was 22.9%, associated with severely reduced calf circumference (OR 7.1, 95% CI 2.3, 22.3).
ContextConfirms high malnutrition and sarcopenia burden in adults on hemodialysis in Panama, with calf circumference as a practical marker; aligns with prior evidence but highlights implementation gaps in routine care.
No standard claimed for this paper

Every paper is compared to the standard governing its question. This one is not: either no standard in the corpus matches it, or the comparison did not hold up on review and was withdrawn rather than published unverified. Both are logged.
