INTRODUCTION: The construction of reliable, reusable clinical code sets is essential when re-using Electronic Health Record (EHR) data for research. Yet code set definitions are rarely transparent and their sharing is almost non-existent. There is a lack of methodological standards for the management (construction, sharing, revision and reuse) of clinical code sets which needs to be addressed to ensure the reliability and credibility of studies which use code sets. OBJECTIVE: To review methodological literature on the management of sets of clinical codes used in research on clinical databases and to provide a list of best practice recommendations for future studies and software tools...

The alteration of wild populations has been discussed as a solution to a number of humanity's most pressing ecological and public health concerns. Enabled by the recent revolution in genome editing, clustered regularly interspaced short palindromic repeats (CRISPR) gene drives-selfish genetic elements that can spread through populations even if they confer no advantage to their host organism-are rapidly emerging as the most promising approach. However, before real-world applications are considered, it is imperative to develop a clear understanding of the outcomes of drive release in nature...

Early health technology assessment is increasingly being used to support health economic evidence development during early stages of clinical research. Such early models can be used to inform research and development about the design and management of new medical technologies to mitigate the risks, perceived by industry and the public sector, associated with market access and reimbursement. Over the past 25 years it has been suggested that health economic evaluation in the early stages may benefit the development and diffusion of medical products...

The gut microbiota is implicated in numerous aspects of health and disease, but dissecting these connections is challenging because genetic tools for gut anaerobes are limited. Inducible promoters are particularly valuable tools because these platforms allow real-time analysis of the contribution of microbiome gene products to community assembly, host physiology, and disease. We developed a panel of tunable expression platforms for the prominent genus Bacteroides in which gene expression is controlled by a synthetic inducer...

Safety analysis is centred on identifying a set of hazards that form the basis of risk assessment. In healthcare, hazards are potential sources of harm to patients and as such the risk of these has to be assessed and managed. With the increased reliance on Health IT systems in health and social care settings, some of these hazards are associated with the development and use of these systems. In this paper we examine current practices in hazard identification, focusing on how clinicians and engineers approach this task within the Health IT safety assurance process...

Notwithstanding important contributions of the Triple Aim, uncritical enthusiasm regarding the implications of the framework may be leading to inconsistent use, particularly when applied at the health system level, which goes beyond the original positioning of the framework as a strategic organizing principle to guide improvement initiatives at the organizational or local community level. We systematically identified uses of the Triple Aim that extended beyond its original intention to focus on uses at the whole health system level, to assess convergence and divergence with the original definition...

The human nervous system is a vast network carrying not only sensory and movement information, but also information to and from our organs, intimately linking it to our overall health. Scientists and engineers have been working for decades to tap into this network and 'crack the neural code' by decoding neural signals and learning how to 'speak' the language of the nervous system. Progress has been made in developing neural decoding methods to decipher brain activity and bioelectronic technologies to treat rheumatoid arthritis, paralysis, epilepsy and for diagnosing brain-related diseases such as Parkinson's and Alzheimer's disease...

BACKGROUND: Both health care professionals and nonprofessionals seek medical information on the Internet. Using Web-based search engine searches to detect epidemic diseases has, however, been problematic. Physician's databases (PD) is a chargeable evidence-based medicine (EBM) portal on the Internet for health care professionals and is available throughout the entire health care system in Finland. Lyme borreliosis (LB), a well-defined disease model, shows temporal and regional variation in Finland...

For a sensor fault diagnostic system of aircraft engines, the health performance degradation is an inevitable interference that cannot be neglected. To address this issue, this paper investigates an integrated on-line sensor fault diagnostic scheme for a commercial aircraft engine based on a sliding mode observer (SMO). In this approach, one sliding mode observer is designed for engine health performance tracking, and another for sensor fault reconstruction. Both observers are employed in in-flight applications...

Background: Photocopiers emit large amounts of nanoparticles (NP) and are a significant source of indoor air pollution. These emissions induce airway inflammation, irritation, and systemic oxidative stress in humans, lung injury and inflammation in animals, and cytotoxicity and epigenetic modifications in vitro. However, little is known regarding NP exposures at the workstation in the photocopy work environment, or the extent and use of emission controls. Objective: To survey the photocopy work environment with regards to emissions controls and to evaluate IAQ with emphasis on NP exposure at the operator's workstation...

Bioinstrumentation engineers have long been creating platforms to study cell health and disease. It becomes necessary to ensure that such cell-probing tools do not themselves harm cells through complex stressors resulting from their design or operational conditions. Here, we present multiplexed cell-based sensors to simultaneously quantify stress induced by diverse mechanisms such as shear stress, DNA damage, and heat shock. Our sensors do not require additional reagents and can be conveniently quantified by flow cytometry and real-time imaging...

BACKGROUND: Lead (Pb) is a toxic substance with well-known, multiple, long-term, adverse health outcomes. Shooting guns at firing ranges is an occupational necessity for security personnel, police officers, members of the military, and increasingly a recreational activity by the public. In the United States alone, an estimated 16,000-18,000 firing ranges exist. Discharge of Pb dust and gases is a consequence of shooting guns. METHODS: The objectives of this study are to review the literature on blood lead levels (BLLs) and potential adverse health effects associated with the shooting population...
