ReviewDiet and dietary supplement intervention trials for the prevention of prostate cancer recurrence: a review of the randomized controlled trial evidence.
We review the effect of diet and dietary supplement interventions on prostate cancer progression, recurrence and survival. ⋯ A limited number of randomized controlled trials were identified in which diet and dietary supplement interventions appeared to slow disease progression in men with prostate cancer, although results vary. Studies were limited by reliance on the surrogate biomarker prostate specific antigen, sample size and study duration. Well designed trials are warranted to expand knowledge, replicate findings and further assess the impact of diet and dietary supplement interventions on recurrence and treatment associated morbidities.

Factors predicting renal functional outcome after partial nephrectomy.
Compared to radical nephrectomy, partial nephrectomy better preserves renal parenchyma and function. Although several clinical factors may impact renal function after partial nephrectomy including preoperative function, age, gender and comorbidities, the contributions of tumor and surgical factors have not been well studied. We evaluate independent factors predicting functional outcomes after partial nephrectomy. ⋯ Lower preoperative glomerular filtration rate, solitary kidney, older age, gender, tumor size and longer ischemic interval all predicted lower glomerular filtration rate after partial nephrectomy. Therefore, duration of renal ischemia is the strongest modifiable surgical risk factor for decreased renal function after partial nephrectomy, and efforts to limit ischemic time and injury should be pursued in open and laparoscopic partial nephrectomy.

Training on a virtual reality laparoscopic simulator improves performance of an unfamiliar live laparoscopic procedure.
Virtual reality simulators provide a safe and efficient means of acquiring laparoscopic skills. We evaluated whether training on a virtual reality laparoscopic cholecystectomy simulator (Lap Mentor) improves the performance of a live, unrelated laparoscopic urological procedure. ⋯ Surgical skills acquired as a result of training on a virtual reality laparoscopic simulator are not procedure specific but improve overall surgical skills, thereby translating into superior performance of an unrelated live laparoscopic urological procedure.
