At the first annual Conference on Machine Intelligence in Medical Imaging (C-MIMI), held in September 2016, a conference session on medical image data and datasets for machine learning identified multiple issues. The common theme from attendees was that everyone participating in medical image evaluation with machine learning is data starved. There is an urgent need to find better ways to collect, annotate, and reuse medical imaging data. Unique domain issues with medical image datasets require further study, development, and dissemination of best practices and standards, and a coordinated effort among medical imaging domain experts, medical imaging informaticists, government and industry data scientists, and interested commercial, academic, and government entities...

Purpose To evaluate the prevalence of tumefactive sludge of the gallbladder detected at ultrasonography (US) and to assess whether any clinical and imaging differences exist between benign and malignant tumefactive sludge. Materials and Methods The institutional review board approved this retrospective study. The requirement for informed consent was waived. The study included a cohort (n = 6898) of patients with gallbladder sludge drawn from all adults (n = 115 178) who underwent abdominal US between March 2001 and March 2015...

Amol Verma and Sacha Bhatia's (2016) paper presents policy recommendations that merit serious consideration on a system-wide level. While they make compelling arguments about why provincial governments are ideally suited to adapt Triple Aim innovation, we are concerned that the current health system climate limits this possibility. In our commentary, we present our thoughts about the authors' admittedly aspirational goals and the realities of the pan-Canadian healthcare system. We commence our commentary by confirming our agreement about the potential inherent within the Triple Aim framework...

2-Phenethyl isothiocyanate (PEITC), a natural product found as a conjugate in watercress and other cruciferous vegetables, is an inhibitor of the metabolic activation and lung carcinogenicity of the tobacco carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) in F344 rats and A/J mice. We carried out a clinical trial to determine whether PEITC also inhibits the metabolic activation of NNK in smokers. Cigarette smokers were recruited and asked to smoke cigarettes containing deuterium-labeled [pyridine-D4]NNK for an acclimation period of at least 1 week...

OBJECTIVE: We explored the effect of autonomous and controlled motivation on outcomes for patients undergoing inpatient treatment for Anorexia Nervosa (AN). METHOD: Data on 80 patients with AN were available for the start of treatment, and for 49 at end of treatment. Patients completed measures of autonomous and controlled motivation, eating disorder symptoms and attitudes, and comorbid psychopathology at the start and end of treatment. RESULTS: Patients showed significant improvements on eating symptoms and comorbid psychopathology over the course of treatment...

BACKGROUND: The aim of this study was to evaluate the safety and efficacy of the Lumax 740(®) Implantable Cardioverter Defibrillator (ICD) system in patients undergoing a defined 1.5 Tesla (T) MRI. MATERIALS AND METHODS: Between November 2013 and April 2014, eighteen patients (age range, 41-78 years; mean age, 64 years) implanted with a Lumax 740(®) ICD system for at least 6 weeks before an MRI were enrolled into this single-center feasibility study. The local ethics committee approved the study before patients gave written informed consent...
