Purpose: Physical activity studies involving bariatric surgery patients tend to be short-term or cross-sectional investigations. Longer-term studies are limited and typically consist of relatively brief objective measurement periods used to generalize activity patterns. Very little research combines objective measurements with structured interviews to determine both the patterns and related factors of long-term physical activity among patients undergoing bariatric surgery.

As there is no general consensus on management of acute ulcer perforations, we compare two methods of surgical repair: the most commonly performed procedure, suturing of ulcer with or without omental patch versus revision gastrojejunostomy (RG).

Summary Background Data: Bariatric surgery may be a viable option for patients with cirrhosis and extreme obesity. However, the risk of liver decompensation after surgery is not thoroughly investigated.
Background: Obesity-associated elevations in glomerular filtration rate (GFR) are common and may play a role in the development of kidney disease, so identifying the underlying mechanism is important. We therefore studied whether reductions in dietary protein intake, which is known to modulate GFR, explain why GFR decreases after bariatric surgery-induced weight loss.
Study Design: Cohort study with participants as their own controls.
Background/aims: Identifying the best method to estimate the glomerular filtration rate (GFR) in bariatric surgery patients has important implications for the clinical care of obese patients and research into the impact of obesity and weight reduction on kidney health. We therefore performed such an analysis in patients before and after surgical weight loss.
Methods: Fasting measured GFR (mGFR) by plasma iohexol clearance before and after bariatric surgery was obtained in 36 severely obese individuals.
Obesity is associated with glomerular hyperfiltration and increased urinary protein excretion, as well as structural and functional changes that lead to kidney disease and failure. Dietary protein mimics obesity's effects on the glomerular filtration rate (GFR) and proteinuria and, in certain circumstances, may have the potential to adversely affect kidney function. Here we tested the hypothesis that dietary protein independently explains elevations in the GFR and proteinuria found in obese persons with a normal serum creatinine.

Methods: Using a cross-sectional design, iohexol clearance and disposition was measured, an optimal sampling schedule was identified, and the reliability of GFR-estimating methods was described in 29 obese individuals with normal serum creatinine levels. Iohexol disposition was measured using population pharmacokinetics.
Purpose: Although estrogens have known antitumor activity in androgen independent prostate cancer, the best studied agent, diethylstilbestrol, is no longer commercially available in the United States. We tested 2 doses of the conjugated estrogen Premarin(R) in patients with androgen independent prostate cancer to determine the efficacy and safety of this widely available medication.
Materials And Methods: A total of 45 patients with progressive androgen independent prostate cancer were randomly assigned to receive Premarin 1.
