Appropriate methods for monitoring of the safety of medical devices introduced into clinical practice have been elusive to develop and implement. A novel approach is the application of Bayesian updating, which incorporates existing knowledge regarding event rates into the estimation of risk. This framework has been shown in other domains to be data efficient and to address some of the limitatio...

background: work-related diseases contribute immensely to the global burden of diseases. better understanding of attitudes of health care workers towards occupational safety and health (osh) is important for planning. objective: to assess the attitude of medical students towards osh around the globe. methods: a questionnaire assessing the attitude towards osh was administered to medical and par...

Various safety-critical devices, such as industrial control systems, medical devices, and home automation systems, are configured through web interfaces from remote hosts that are standard PCs. The communication link from the host to the safety-critical device is typically easy to protect, but if the host gets compromised, the adversary can manipulate any user-provided configuration settings wi...

Interactive medical devices such as infusion pumps, monitors and diagnostic devices help save lives. However, they may also fail in use and patient harm ensue. It is not just that the software and hardware should meet their specification. The design should help ensure users do not make mistakes. Safety factors are more important as medical devices become mobile and are used by patients as part ...

Polyvinyl alcohol (PVA) is a synthetic polymer derived from polyvinyl acetate through partial or full hydroxylation. PVA is commonly used in medical devices due to its low protein adsorption characteristics, biocompatibility, high water solubility, and chemical resistance. Some of the most common medical uses of PVA are in soft contact lenses, eye drops, embolization particles, tissue adhesion ...

■ Abstract All materials intended for application in humans as biomaterials, medical devices, or prostheses undergo tissue responses when implanted into living tissue. This review first describes fundamental aspects of tissue responses to materials, which are commonly described as the tissue response continuum. These actions involve fundamental aspects of tissue responses including injury, infl...

BACKGROUND There is an association between cryptogenic stroke and patent foramen ovale (PFO). The optimal treatment strategy for secondary prevention remains unclear. The purpose of this study was to analyze aggregate data examining the safety and efficacy of transcatheter device closure versus standard medical therapy in patients with PFO and cryptogenic stroke. METHODS A search of published...
