BACKGROUND: Despite the high prevalence of substance use disorders, associated comorbidities and the evidence-base upon which to base clinical practice, most health systems have not invested in standardised training of healthcare providers in addiction medicine. As a result, people with substance use disorders often receive inadequate care, at the cost of quality of life and enormous direct health care costs and indirect societal costs. Therefore, we undertook this study to assess the views of international scholars, representing different countries, on the core set of addiction medicine competencies that need to be covered in medical education...

Axel Wolf, Lucy Moore, Doris Lydahl, Öncel Naldemirci, Mark Elam, Nicky Britten
OBJECTIVE: Although conceptual definitions of person-centred care (PCC) vary, most models value the involvement of patients through patient-professional partnerships. While this may increase patients' sense of responsibility and control, research is needed to further understand how this partnership is created and perceived. This study aims to explore the realities of partnership as perceived by patients and health professionals in everyday PCC practice. DESIGN: Qualitative study employing a thematic analysis of semistructured interviews with professionals and patients...

In 2011, an Institute of Medicine report on health information technology (IT) and patient safety highlighted that building health-IT for safer use is a shared responsibility between key stakeholders including: "vendors, care providers, healthcare organizations, health-IT departments, and public and private agencies". Use of electronic health records (EHRs) involves all these stakeholders, but they often have conflicting priorities and requirements. Since 2011, the concept of shared responsibility has gained little traction and EHR developers and users continue to attribute the substantial, long list of problems to each other...

PURPOSE: To assess the amide proton transfer-weighted (APTw) MRI features of isocitrate dehydrogenase (IDH)-wildtype and IDH-mutant grade II gliomas and to test the hypothesis that the APTw signal is a surrogate imaging marker for identifying IDH mutation status preoperatively. METHODS: Twenty-seven patients with pathologically confirmed low-grade glioma, who were previously scanned at 3T, were retrospectively analyzed. The Mann-Whitney test was used to evaluate relationships between APTw intensities for IDH-mutant and IDH-wildtype groups, and receiver operator characteristic (ROC) analysis was used to assess the diagnostic performance of APTw...

PURPOSE: An emerging topic in diffusion magnetic resonance is imaging blood microcirculation alongside water diffusion using the intravoxel incoherent motion (IVIM) model. Recently, a combined IVIM diffusion tensor imaging (IVIM-DTI) model was proposed, which accounts for both anisotropic pseudo-diffusion due to blood microcirculation and anisotropic diffusion due to tissue microstructures. In this article, we propose a robust IVIM-DTI approach for simultaneous diffusion and pseudo-diffusion tensor imaging...

#14
Bernard J Moxham, Diogo Pais
Medical and dental curricula, together with anatomical sciences courses, are increasingly having to change, mainly because there is a drive to being what is termed, without adequate definition, 'clinically relevant'. The concept of 'clinical anatomy' has accordingly been invented and it is expected that, at all times, the teaching of anatomy is directly focussed on clinical scenarios, meaning almost invariably the 'disease-based model of medicine and dentistry'. Furthermore, students are not expected to have a detailed knowledge of gross anatomy and the time devoted to teaching and learning the subject has decreased significantly...

PURPOSE: To develop a novel technique for reliable quantification of bone marrow fat content and composition using in vivo MR spectroscopy (MRS). METHODS: An MRS quantification method combining both advantages of Voigt line shape model and time-domain analysis was developed. The proposed method was tested using computer-simulated data and in vivo data acquired at lumbar vertebral bodies of 23 subjects (age, 83.8 ± 3.7 y; male, n = 13; female, n = 10) from L1 to L4...

Zhiyong Zhang, Lucio Frydman
PURPOSE: Cross-term spatiotemporal encoding (xSPEN) is a single-shot approach with exceptional immunity to field heterogeneities, the images of which faithfully deliver 2D spatial distributions without requiring a priori information or using postacquisition corrections. xSPEN, however, suffers from signal-to-noise ratio penalties due to its non-Fourier nature and due to diffusion losses-especially when seeking high resolution. This study explores partial Fourier transform approaches that, acting along either the readout or the spatiotemporally encoded dimensions, reduce these penalties...

Matthias Weigel, Oliver Bieri
PURPOSE: To establish a novel approach for fast high-resolution spinal cord (SC) imaging using averaged magnetization inversion recovery acquisitions (AMIRA). METHODS: The AMIRA concept is based on an inversion recovery (IR) prepared, segmented, and time-limited cine balanced steady state free precession sequence. Typically, for the fastest SC imaging without any signal averaging, eight consecutive images in time with an in-plane resolution of 0.67 × 0.67 mm(2) and 6 mm to 8 mm slice thickness are acquired in 51 s...

Gaëtan Rensonnet, Benoît Scherrer, Simon K Warfield, Benoît Macq, Maxime Taquet
PURPOSE: To assess the validity of the superposition approximation for crossing fascicles, i.e., the assumption that the total diffusion-weighted MRI signal is the sum of the signals arising from each fascicle independently, even when the fascicles intermingle in a voxel. METHODS: Monte Carlo simulations were used to study the impact of the approximation on the diffusion-weighted MRI signal and to assess whether this approximate model allows microstructural features of interwoven fascicles to be accurately estimated, despite signal differences...

The expanding international wildlife trade, combined with a lack of surveillance for key animal diseases in most countries, represents a potential pathway for transboundary disease movement. While the international wildlife trade represents over US $300 billion per year industry involving exchange of billions of individual animals, animal products, and plants as traditional medicines, meat from wild animals, trophies, live exotic pets, commercial products and food, surveillance and reporting of OIE-Listed diseases in wildlife are often opportunistic...
