Malnutrition at the initiation of dialysis is a strong predictor subsequent increased mortality on dialysis. Few studies have documented relationship between progression renal failure and spontaneous dietary protein intake (DPI) other indices malnutrition. In this prospective study, function was sequentially measured by creatinine clearance (CrCl) DPI 24-h urine collection; simultaneously, multiple sequential biochemical nutritional indices, including serum albumin, transferrin, prealbumin,...

The authors examined pathology from patients with renal cancer (RCC) treated IL-2 to determine response rates for clear cell and variant RCC identify histologic features that predict response. Pathology specimens were reviewed by a single pathologist who was blinded both the prior interpretation therapeutic Findings correlated therapy. Evaluable obtained 231 patients. Of 163 primary RCCs, rate 21% (30/146) versus 6% (1/17) or indeterminate type (P = 0.20). For carcinomas, associated presence...

Prostate cancer is the most common visceral malignancy in men. As tumor testosterone dependent, a frequent treatment modality involves therapy with GnRH agonists (GnRH-a) resulting hypogonadism. Because essential for maintenance of bone mass men, we postulated that GnRH-a would negatively impact skeletal integrity. We compared mineral density (BMD), biochemical markers turnover, and body composition 60 men prostate (19 receiving 41 eugonadal men) BMD 197 community-living healthy controls...

The incidence of bronchopulmonary dysplasia (BPD) increased from 10.6% in 1976 through 1980, to 21.7% (1981 1985), and 32.9% (1986 1990) very low birth weight neonates (1500 g or less) admitted the Vanderbilt Neonatal Intensive Care Unit, while there was a concurrent decline neonatal death (NEOD) during same periods (26.4%, 18.3%, 15.9%, respectively).

Elderly women on combination therapy with alendronate and hormone replacement for osteoporosis have greater gains in bone mass than those monotherapy. It is not known whether early changes markers can predict the long-term density therapy. We assessed biochemical of turnover [urine N-telopeptide cross-linked collagen type 1 (NTx), serum bone-specific alkaline phosphatase, osteocalcin] every 6 months 3 yr a double-blind, placebo-controlled, randomized clinical trial. After 3-month run-in...

Background Many data are available regarding cardiac risk in patients with coronary artery disease undergoing noncardiac surgery, but few for hypertrophic cardiomyopathy and asymmetric septal hypertrophy. Methods Seventy-seven hypertrophy were identified whom an echocardiogram had been performed within 24 months of surgery. Patients' charts reviewed surgical operations, including length type anesthesia, intravascular monitoring used. Data adverse perioperative events also gathered. Results...

Abstract A 3 bp deletion of condon 508 (phenylalanine) the cystic fibrosis (CF) gene constitutes mutation most CF chromosomes. The frequency this (referred to as ΔF508), varies considerably between populations, ranging form 26% mutations in Turkey 88% Denmark. To determine ΔF508 Brazilian Caucasoid patients, we used direct polymerase chain reacion (PCR) amplification DNA obtained from dried blood spots on Guthrie cards, followed by ethidium bromide staining gels. Although overall was 47% 380...

The purpose of this article is to evaluate single-source dual-energy CT (DECT) for distinguishing benign and indeterminate adrenal nodules, with attention the effects phase IV contrast enhancement.A retrospective review revealed 273 contrast-enhanced abdominal DECT examinations from November 2009 through March 2012. Fifty nodules 0.8 cm or larger were identified in 41 patients (22 women 19 men; average age, 66 years; age range, 36-88 years). postprocessing measurements independently...

Gustatory sweating has been only rarely reported in diabetes mellitus and is thought to be due axonal regeneration within the autonomic nervous system. We investigated relationship of gustatory other diabetic complications. 196 patients four groups (diabetic nephropathy, neuropathy, controls, non-diabetic renal failure) were questioned about sweating. Somatic neuropathy assessed by clinical signs, vibration perception threshold, heart rate variability. Sixty-nine percent with nephropathy 36%...

We determined if surfactant treatment effect can be enhanced by mechanical volume recruitment during administration measuring functional residual capacity, tidal volume, the alveolar portion of dynamic compliance respiratory system, a/A ratio, and PaCO2 before after to rabbits with lung injury induced airway lavage. There was improvement in all function indices when given recruitment, but without only index show significant ratio oxygenation. These results support hypothesis that terminal...
