Systematic reviews (SRs) can help decision makers interpret the deluge of published biomedical literature. However, a SR may be of limited use if the methods used to conduct the SR are flawed, and reporting of the SR is incomplete. To our knowledge, since 2004 there has been no cross-sectional study of the prevalence, focus, and completeness of reporting of SRs across different specialties. Therefore, the aim of our study was to investigate the epidemiological and reporting characteristics of a more recent cross-section of SRs.

In January 2013, the Swiss Medical Board, an independent health technology assessment initiative under the auspices of the Conference of Health Ministers of the Swiss Cantons, the Swiss Medical Association, and the Swiss Academy of Medical Sciences, was mandated to prepare a review of mammography screening. The two of us, a medical ethicist and a clinical epidemiologist, were members of the expert panel that appraised the evidence and its implications. The other members were a clinical pharmacologist, an oncologic surgeon, a nurse scientist, a lawyer, and a health economist. As we embarked on the project, we were aware of the . . .

The objective of this study is to provide an epidemiologic analysis of medication errors occurring outside of health care facilities that result in serious medical outcomes (defined by the National Poison Database System as “moderate effect,” “major effect,” “death,” or “death, indirect report”).

Abstract In this review of the literature on surface-enhanced Raman scattering (SERS), we describe recent developments in SERS techniques in medical technology. The SERS technique has developed rapidly in the last few years as a result of fascinating advancements in instrumentation and the ability to interpret Raman data using high-processional, computer-aided programs. SERS has many advantages over ordinary spectroscopic analytical techniques - such as extremely high sensitivity, molecular selectivity, intense signal and great precision - that can be leveraged to address complex medical diagnostics problems. This review focuses on the SERS-active substrate, as well as major advances in cancer and bacteria detection and imaging. Finally, we present a perspective on anticipated future advancements in SERS techniques to address some of the most critical challenges in the areas of diagnostics, detection, and sensing.

Many research fields, including psychology and basic medical sciences, struggle with poor reproducibility of reported studies. Biomedical and health informatics is unlikely to be immune to these challenges. This paper explores replication in informatics and the unique challenges the discipline faces.

Objectives: This paper addresses the issue of interdisciplinary collaboration between medical and non-medical professions in health and social care. The introduction defines basic terms such as interdisciplinary cooperation, interdisciplinary team, and health and social care. Additionally, it highlights the significance and contribution of interdisciplinary collaboration in the care of the patient/client in health and social care. The aim of the paper is to identify factors influencing the process of interdisciplinary collaboration between, in particular, social workers and physicians. In compliance with the main goal of the research, the following partial goals were included: 1) to identify factors that limit the process of interdisciplinary collaboration between social workers and physicians, and 2) to identify factors which support the process of interdisciplinary collaboration between social workers and physicians.
