Comparison of level of cognitive process between case-based items and non-case-based items of the interuniversity progress test of medicine in the Netherlands.

J Educ Eval Health Prof 2018 12;15:28. Epub 2018 Dec 12.

Department of Cardiology, Catharina Hospital, and Department of Educational Development and Research, and Faculty of Health, Medicine and Life Sciences, Maastricht University, The Netherlands.

Purpose: It is assumed that case-based questions require higher order cognitive processing, whereas questions that are not case-based require lower order cognitive processing. In this study, we investigated to what extent case-based questions and questions that are not case-based, relate to Bloom's taxonomy.

Methods: In this article, 4800 questions of the Progress Test were classified whether it was a case-based question and the level of Bloom's taxonomy. Read More

Postimplant biological aortic prosthesis degeneration: challenges in transcatheter valve implants.

Eur J Cardiothorac Surg 2018 Dec 11. Epub 2018 Dec 11.

Department of Cardio-Thoracic Surgery, Maastricht University Medical Centre, Maastricht, Netherlands.

Surgical aortic valve replacement (SAVR) is highly effective and can be achieved with relatively low risk in patients with severe aortic stenosis. Bioprostheses have been used most frequently during the past 60 years. However, the function of biological valves usually declines after 10-15 years from implant when structural valve degeneration occurs often mandating a reoperation once valve dysfunction becomes haemodynamically significant.

Diurnal distribution of carbohydrates and fat affects substrate oxidation and adipokine secretion in humans.

Am J Clin Nutr 2018 Dec;108(6):1209-1219

Departments of Clinical Nutrition.

Background: A diet in which fat is mainly eaten in the morning and carbohydrates mainly in the evening (compared with the reverse order) was recently shown to worsen glycemic control in people with prediabetes.

Objective: We investigated the effects of these dietary patterns on energy metabolism, and on the daily profiles of circulating lipids, adipokines, and inflammatory markers.

Design: In a randomized controlled crossover trial, 29 nonobese men (with normal glucose tolerance, n = 18; or impaired fasting glucose/glucose tolerance, n = 11) underwent 2 isocaloric 4-wk diets: 1) carbohydrate-rich meals until 1330 and fat-rich meals between 1630 and 2200 (HC/HF); or 2) the inverse sequence of meals (HF/HC).

A 12-wk whole-grain wheat intervention protects against hepatic fat: the Graandioos study, a randomized trial in overweight subjects.

Am J Clin Nutr 2018 Dec;108(6):1264-1274

Wageningen University, Division of Human Nutrition, Wageningen, The Netherlands.

Background: Whole-grain wheat (WGW) is described as nutritionally superior to refined wheat (RW) and thus advocated as the healthy choice, although evidence from intervention studies is often inconsistent. The liver, as the central organ in energy metabolism, might be an important target organ for WGW interventions.

Department of Radiology, Miller Research Building Molecular Imaging Service Center, Johns Hopkins University, Baltimore, Maryland.

Preclinical noninvasive imaging can be an indispensable tool for studying animal models of disease. In vivo imaging to assess anatomical, functional, and molecular features requires verification by a comparison to the macroscopic and microscopic morphological features, since all noninvasive in vivo imaging methods have much lower resolution than standard histopathology. Comprehensive pathological evaluation of the animal model is underutilized; yet, many institutions have veterinary or human pathologists with necessary comparative pathology expertise. Read More

Department of Anaesthesia, Intensive Care Medicine and Pain Medicine, Division of Cardiac Thoracic Vascular Anaesthesia and Intensive Care Medicine, Medical University of Vienna, Vienna, Austria.

Exposure to heparin and protamine during cardiac surgery on cardiopulmonary bypass (CPB) may trigger heparin-induced thrombocytopaenia and/or protamine-induced thrombocytopaenia. Further surgery on CPB with heparin and protamine in the presence of these antibodies implies increased thromboembolic risk.

Centre for Molecular Medicine and Therapeutics, Department of Medical Genetics, BC Children's Hospital Research Institute, University of British Columbia, Vancouver, Canada.

Motivation: Deciphering the functional roles of cis-regulatory variants is a critical challenge in genome analysis and interpretation. It has been hypothesized that altered transcription factor (TF) binding events are a central mechanism by which cis-regulatory variants impact gene expression levels. However, we lack a computational framework to understand and quantify such mechanistic contributions. Read More

Examining associations between physical activity and cardiovascular mortality using negative control outcomes.

Int J Epidemiol 2018 Dec 11. Epub 2018 Dec 11.

Charles Perkins Centre, University of Sydney, Sydney, Australia.

Background: The purpose of a negative control is to reproduce a condition that cannot involve the hypothesized causal mechanism, but does involve the same sources of bias and confounding that may distort the primary association of interest. Observational studies suggest physical inactivity is a major risk factor for cardiovascular disease (CVD), although potential sources of bias, including reverse causation and residual confounding, make it difficult to infer causality. The aim was to employ a negative control outcome to explore the extent to which the association between physical activity and CVD mortality is explained by confounding. Read More

Cumulative live birth rate prognosis based on the number of aspirated oocytes in previous ART cycles.

Hum Reprod 2018 Dec 12. Epub 2018 Dec 12.

Department of Obstetrics and Gynecology, Copenhagen University Hospital Hvidovre, Kettegård Allé 26, Hvidovre, Denmark.

Study Question: Is the number of aspirated oocytes in the first ART cycle associated with the cumulative live birthrates (CLBR) in subsequent cycles?

Summary Answer: The number of aspirated oocytes in the first cycle was associated with CLBR in subsequent cycles. Previous treatment response predicts outcome in future cycles.

What Is Known Already: Previous reports have shown a positive association between the number of retrieved oocytes and live birthrate per fresh treatment cycle. Read More
