BACKGROUND Approximately 70% of all suicides in patients aged >60 years are attributed to physical illness, with higher rates noted in patients with cancer. The purpose of the current study was to characterize suicide rates among patients with genitourinary cancers and identify factors associated with suicide in this specific cohort. METHODS Patients with(More)

METHODS The PubMed and Cochrane databases were searched up to January 2015 for clinical trials and case reports describing therapeutic ketamine administration to patients presenting with SI/suicidality. Searches were also conducted for(More)
PURPOSE To analyze the association of marital status and survival of patients with ACC using a population-based database. MATERIAL AND METHODS Patients with ACC were abstracted from the Surveillance Epidemiology and End Results (SEER) database from 1988-2010 (n=1271). Variables included marital status (married vs single/divorced/widowed (SDW)), gender,(More)
BACKGROUND While RCC is the most common primary renal neoplasm, few cases of ipsilateral renal lesions of different RCC histologic subtypes have been described. The objective of this study was to evaluate our experience with synchronous, histologically unique, primary renal neoplasms within the same kidney. PATIENTS AND METHODS We retrospectively analyzed(More)
PURPOSE Compared to the general population, suicide is more common in the elderly and in patients with cancer. We sought to examine the incidence of suicide in patients with bladder cancer and evaluate the impact of radical cystectomy in this high-risk population. METHODS Patients diagnosed with urothelial carcinoma from 1988 to 2010 were identified in(More)
BACKGROUND Epidemiological data suggest that omega-6 (ω-6) fatty acids (FAs) may be associated with cancer incidence and/or cancer mortality, whereas ω-3 FAs are potentially protective. We examined the association of the ratio of ω-6 to ω-3 FA (ω-6:ω-3) and individual FA components with pathological results among men with prostate cancer (PCa) undergoing(More)
PURPOSE To explore the association of body mass index (BMI) and comorbidity with renal function after nephrectomy. MATERIALS AND METHODS We retrospectively analyzed 263 patients submitted to partial or radical nephrectomy from 2000-2013.
