Higher abdominal fat area associates with lower donor kidney function before and after living kidney donation.

Central body fat distribution affects kidney function. Abdominal fat measurements using computed tomography (CT) may prove superior in assessing body composition-related kidney risk in living kidney donors. This retrospective cohort study including 550 kidney donors aimed to determine the association between CT-measured abdominal fat areas and kidney function before and after donor nephrectomy.

CT-assessed sarcopenia and immune-related adverse events in patients with lung cancer: A competing risk time-to-event analysis.

Background: Immune checkpoint inhibitors (ICIs) can induce immune-related adverse events (irAEs). This study investigates the relationship between CT-assessed sarcopenia and irAEs in patients with lung cancer who are receiving ICIs.

Methods: Patients were enrolled if they had lung cancer treated with ICIs at the University Medical Center Groningen (2015-2021) and had undergone low-dose CT scans that included the third lumbar vertebral level (L3).

Analyzing body composition in living kidney donors: impact on post-transplant kidney function.

Living donor kidney transplantation boasts superior patient and graft survival rates compared to deceased donor kidney transplantation. However, the impact of living donor body composition (BC) on post-transplant kidney function remains uncertain. In a cohort of 293 living kidney donor-recipients pairs, we utilized linear mixed model analyses, adjusted for time and including a multiplicative interaction term of time with the donor body composition measure, and found no significant associations between any donor BC measure and the annual change in recipient post-transplantation estimated glomerular filtration rate (eGFR) [donor body mass index (BMI): =-0.

Metabolic Changes After Bronchoscopic Lung Volume Reduction With Endobronchial Valves in COPD Patients.

Objectives: Little is known about the effect of bronchoscopic lung volume reduction using endobronchial valves (BLVR-EBV) on extrapulmonary manifestations like body composition, muscle function or metabolism. Pulmonary rehabilitation (PR) clearly addresses extrapulmonary manifestations of COPD, including physical inactivity and low muscle mass. However, the added impact of BLVR-EBV+PR remains unknown.
