Association between hypovitaminosis D and sarcopenic obesity in patients with chronic kidney disease stages 3 and 4.

The relationship between sarcopenic obesity and hypovitaminosis D in individuals with chronic kidney disease is complex and has significant impacts on muscle and bone health. An observational, cross-sectional, and analytical study was conducted to analyze possible associations between serum vitamin D levels and sarcopenic obesity in patients with chronic kidney disease stages 3 and 4 in a cohort of patients under nephrology care. The presence of sarcopenic obesity was assessed using bioimpedance criteria, and vitamin D levels were measured and recorded for each patient.

Baseline in vivo, ex vivo and molecular responses of Plasmodium falciparum to artemether and lumefantrine in three endemic zones for malaria in Colombia.

Background: Colombia began using artemisinin-based combination therapies for the treatment of uncomplicated Plasmodium falciparum malaria in 2006. It is necessary to implement resistance surveillance to antimalarial drugs in order to promptly detect changes in parasite susceptibility. The aim of this study was to establish a susceptibility baseline of P.

Implantation of peritoneal catheters by laparotomy: nephrologists obtained similar results to general surgeons.

Purpose: To analyze the complications and costs of minilaparotomies performed by a nephrologist (group A) compared with conventional laparotomies performed by a surgeon (group B) for peritoneal catheter implantation.

Setting: Two university hospitals (Santa Sofia and Caldas) in Manizales, Caldas, Colombia.

Methods: The study included stage 5 chronic kidney disease patients, with indication of renal replacement therapy, who were candidates for peritoneal dialysis and gave informed consent for a peritoneal catheter implant.

Fungal peritonitis in peritoneal dialysis patients: successful prophylaxis with fluconazole, as demonstrated by prospective randomized control trial.

Objectives: To determine whether oral administration of the antifungal fluconazole during the entire period of treatment of bacterial peritonitis (BP), exit-site infection (ESI), or tunnel infection (TI) prevents later appearance of fungal peritonitis (called secondary) in patients with chronic kidney disease stage 5 in a peritoneal dialysis (PD) program. ♢

Patients And Methods: All patients treated in the PD program in RTS Ltda Sucursal Caldas, during the period 1 June 2004 to 30 October 2007 were screened. Patients that had infectious bacterial complications (BP, ESI, TI) were included in a prospective randomized trial to receive or not receive oral fluconazole (200 mg every 48 hours) throughout the time period required by the administration of therapeutic antibiotics via any route.
