Objective To estimate the prevalence of abnormal glomerular filtration rate in elderly patients with solid tumors.Methods A retrospective study with patients aged >65 years diagnosed with solid tumors between January 2007 and December 2011 in a cancer center. The following data were collected: sex, age, serum creatinine at the time of diagnosis and type of tumor. Renal function was calculated using abbreviated Modification of Diet in Renal Disease (MDRD) formulae and then staged in accordance with the clinical practice guidelines […]

Objective:To compare low and high MELD scores and investigate whether existing renal dysfunction has an effect on transplant outcome.METHODS:Data was prospectively collected among 237 liver transplants (216 patients) between March 2003 and March 2009. Patients with cirrhotic disease submitted to transplantation were divided into three groups: MELD > 30, MELD < 30, and hepatocellular carcinoma. Renal failure was defined as a ± 25% decline in estimated glomerular filtration rate as observed 1 week after the transplant. Median MELD scores were [...]

ABSTRACTObjective:Considering that the Cockcroft-Gault formula and the equation of diet modification in renal disease are amply used in clinical practice to estimate the glomerular filtration rate, although they seem to have low accuracy in obese patients, the present study intends to evaluate the predictive performance of 12 equations used to estimate the glomerular filtration rate in obese patients.Methods:This is a cross-sectional retrospective study, conducted between 2007 and 2008 and carried out at a university, of 140 patients with severe obesity […]
