BACKGROUND Inflammatory bowel disease (IBD) patients undergo multiple radiological evaluations. AIM To estimate total and abdominal radiation exposure from diagnostic X-ray investigations in IBD patients and the associated risk factors. METHODS Patients with Crohn's disease (CD) or ulcerative colitis (UC) treated in the IBD clinic were recruited.(More)
OBJECTIVE To assess whether antimüllerian hormone (AMH) is a predictor of implantation and/or clinical pregnancy in women undergoing assisted reproductive technology. DESIGN Systematic review and meta-analysis. SETTING Not applicable. PATIENT(S) Women undergoing IVF/intracytoplasmic sperm injection in nondonor cycles. INTERVENTION(S) Measurement of(More)
This paper suggests a new model for reliability demonstration of safety-critical systems, based on the TRW Software Reliability Theory. The paper describes the model; the test equipment required and test strategies based on the various constraints occurring during software development. The paper also compares a new testing method, Single Risk Sequential(More)
CONTEXT There is an abnormal increase in TGF-β1 bioavailability in women with polycystic ovary syndrome (PCOS), which might play a role in the pathophysiology of this syndrome. Vitamin D (VD) supplementation improves various clinical manifestations of PCOS and decreases TGF-β1 levels in several diseases including myelofibrosis. OBJECTIVE The objective of(More)
OBJECTIVE To assess cycle outcomes when antimüllerian hormone (AMH) is ultralow (≤0.16 ng/mL) and to determine which parameters contribute to the probability of cycle cancellation and/or outcome. DESIGN Retrospective analysis. SETTING Not applicable. PATIENT(S) 5,087 (7.3%) fresh and 243 (1.5%) thawed cycles with ultralow AMH values. INTERVENTION(S)(More)
OBJECTIVES To determine the extent of variability in the definitions of the 'trifecta' after radical prostatectomy (undetectable PSA, urinary continence and potency) to be found in the literature. To establish a consensus definition of the trifecta in an effort to standardize criteria and reporting. MATERIALS AND METHODS A systematic review of published(More)
When software reliability demonstration of safety-critical systems by statistical testing is treated as a TAAF (Test, Analyse and Fix) process, an optimal testing policy can be found, which maximises the probability of success of the whole process, over a predetermined period of time. The optimisation problem is formulated, solved by stochastic dynamic(More)
INTRODUCTION Intraoperative biopsy of the apical margin during radical prostatectomy has been recommended as a way to reduce the positive margin rate at this location. However, the enhanced visibility of the apex during robot-assisted radical prostatectomy (RARP) may obviate this need, allowing for the preservation of maximal urethral length. We assessed(More)
