Nutritional considerations with antiobesity medications.

The improved efficacy and generally favorable safety profile of recently approved and emerging antiobesity medications (AOMs), which result in an average weight reduction of ≥15%, represent significant advancement in the treatment of obesity. This narrative review aims to provide practical evidence-based recommendations for nutritional assessment, management, and monitoring of patients treated with AOMs. Prior to treatment, clinicians can identify preexisting nutritional risk factors and counsel their patients on recommended intakes of protein, dietary fiber, micronutrients, and fluids.

Ionizing radiation causes active degradation and reduces matrix synthesis in articular cartilage.

Purpose: Little is known regarding radiation effects on adult articular (joint) cartilage, though joint damage has been reported following cancer treatment or occupational exposures. The aim of this study was to determine if radiation can reduce cartilage matrix production, induce cartilage degradation, or interfere with the anabolic effects of IGF-1.

Materials And Methods: Isolated chondrocytes cultured in monolayers and whole explants harvested from ankles of human donors and knees of pigs were irradiated with 2 or 10 Gy γ-rays, with or without IGF-1 stimulation.
