BACKGROUND Acute tubular necrosis (ATN) has high mortality, especially in patients who require renal replacement therapy (RRT). We prospectively studied the diagnostic accuracy of the urinary excretion of low-molecular-weight proteins and enzymes as predictors of a need for RRT in ATN. METHODS In 73 consecutive patients with initially nonoliguric ATN, we measured urinary excretion of alpha(1)...

OBJECTIVE To evaluate the role of memantine (N-methyl-d-aspartate receptor antagonist) pretreatment for the prevention of spinal cord ischemia after infrarenal aortic clamping in a rabbit model. METHODS Thirty New Zealand White rabbits were divided into 5 different groups of 6 rabbits. Groups 60-7 and 60-5 received oral memantine 60 mg once a day for 7 and 5 days, respectively, and groups 30-...

Pure bovine pancreatic polypeptide (PP) was infused into 23 healthy subjects at doses of 1, 3, and 5 pmol/kg/min over 60 minutes and plasma PP was measured by radioimmunoassay. During the infusions mean plasma levels of 203 +/- 34, 575 +/- 73, and 930 +/- 48 pmol/l respectively were achieved. Mean disappearance half time on stopping the infusion was 6.9 +/- 0.3 min (mean +/- SEM). The metabolic...

OBJECTIVES To assess interobserver reproducibility among ultrasound experts and gynecologists in the prediction by transvaginal ultrasound of deep myometrial and cervical stromal invasion in women with endometrial cancer. METHODS Sonographic videoclips of the uterine corpus and cervix of 53 women with endometrial cancer, examined preoperatively by the same ultrasound expert, were integrated i...

CONTEXT One of the limitations of 13C-urea breath test for Helicobacter pylori infection diagnosis in Brazil is the substrate acquisition in capsule presentation. OBJECTIVES The purpose of this study was to evaluate a capsule-based 13C-urea, manipulated by the Pharmacy Division, for the clinical practice. METHODS Fifty patients underwent the conventional and the capsule breath test. Samples...

BackgroundTo assess the diagnostic accuracy of Mayo Clinic echocardiographic criteria to differentiate constrictive pericarditis (CP) and restrictive cardiomyopathy (RCM).MethodsWe searched electronic databases from inception July 1, 2022. The index tests were criteria. We performed a bivariate random-effects model estimate pooled sensitivity specificity with their 95% confidence interval (CI)....

Physical exercise has been shown to have an important role in the prevention and treatment of arterial hypertension. However, general recommendations are time consuming, which might be detrimental adoption. Based on this, minimal doses suggested as alternative approach this report investigates feasibility effects low volume high effort resistance training for hypertensive patients a hospital se...
