OBJECTIVE The optimal diameter at which replacement of the ascending aorta should be performed in patients with bicuspid aortic valve disease is not known. METHODS We reviewed all patients with bicuspid aortic valves undergoing aortic valve replacement at our institution from 1979 through 1993 (n = 201). Patients undergoing concomitant replacement of the(More)
Understanding the demographic response of free-living animal populations to different drivers is the first step towards reliable prediction of population trends. Penguins have exhibited dramatic declines in population size, and many studies have linked this to bottom-up processes altering the abundance of prey species. The effects of individual traits have(More)
BACKGROUND The prognostic significance of capsular incision (CapI) into tumor during radical prostatectomy (RP) with otherwise organ-confined disease remains uncertain. OBJECTIVE To evaluate the impact of CapI into tumor on oncologic outcome. DESIGN, SETTING, AND PARTICIPANTS A retrospective review of 8110 consecutive patients with prostate cancer(More)
BACKGROUND Metformin may decrease prostate cancer (PCa) risk by reducing hyperinsulinemia-associated carcinogenesis or through direct effects on cancer cells. OBJECTIVE To evaluate the association between metformin use and PCa diagnosis. DESIGN, SETTING, AND PARTICIPANTS We used the Danish Cancer Registry and the Aarhus University Prescription Database(More)
OBJECTIVES To determine the amount of intravenous immune globulin (IVIG) used across indications in Canada and which Canadian medical specialties prescribe IVIG. To assess the proportion of IVIG that was used in appropriate off-label and labelled indications versus those deemed to be inappropriate off-label indications. METHODS In Canada, all IVIG is(More)
Given the lack of randomized evidence comparing trimodal therapy (TMT) to radical cystectomy (RC) for muscle-invasive urothelial carcinoma of the bladder (UCB), we performed an observational cohort study to examine the comparative effectiveness of these two definitive treatments. Within the National Cancer Data Base (2004-2011),we identified 1257 (9.8%) and(More)
PURPOSE Obesity is an established risk factor for clear cell renal cell carcinoma (RCC); however, some reports suggest that RCC developing in obese patients may be more indolent. We investigated the clinical and biologic effect of body mass index (BMI) on treatment outcomes in patients with metastatic RCC. METHODS The impact of BMI (high BMI: ≥ 25 kg/m2 v(More)
PURPOSE Gleason 6 (3+3) is the most commonly diagnosed prostate cancer among men with prostate specific antigen screening, the most histologically well differentiated and is associated with the most favorable prognosis. Despite its prevalence, considerable debate exists regarding the genetic features, clinical significance, natural history, metastatic(More)

All the cases had significantly elevated titres of anti-O157 lipopolysaccharide (LPS) antibodies as detected by the indirect haemagglutination assay. All but one of them had drunk unpasteurized goat's milk from(More)
