BACKGROUND: Several observational studies have suggested that outdoor air pollution may induce or aggravate asthma. However, epidemiological results are inconclusive due to the presence of numerous moderators which influence this association. The goal of this study was to assess the relationship between outdoor air pollutants and moderate or severe asthma exacerbations in children and adults through a systematic review and multilevel meta-analysis. MATERIAL AND METHODS: We searched studies published in English on PubMed, Scopus, and Google Scholar between January 2000 and October 2016...

BACKGROUND: Although health technology assessment (HTA) systems base their decision making process either on economic evaluations or comparative clinical benefit assessment, a central aim of recent approaches to value measurement, including value based assessment and pricing, points towards the incorporation of supplementary evidence and criteria that capture additional dimensions of value. OBJECTIVE: To study the practices, processes and policies of value-assessment for new medicines across eight European countries and the role of HTA beyond economic evaluation and clinical benefit assessment...

The expression of pharmaceutical relevant proteins in E. coli frequently triggers inclusion body (IB) formation caused by protein aggregation. In literature, substantial effort has been invested into the quantification of IB size. But up to this date particle based methods to analyze physical IB properties of representative numbers of IBs lack sensitivity and/or lack orthogonal verification. Using high pressure freezing and automated freeze substitution for transmission electron microscopy (TEM) the cytosolic inclusion body structure was preserved within the cells...

The West African sub-continent is currently experiencing its first, and ironically, the largest and longest Ebola viral diseases (EVD) outbreak ever documented in modern medical history. The current outbreak is significant in several ways, including longevity, magnitude of morbidity and mortality, occurrence outside the traditional niches, rapid spread and potential of becoming a global health tragedy. The authors provided explicit insights into the current and historical background, drivers of the epidemic, societal impacts, status of vaccines and drugs development and proffered recommendations to halt and prevent future occurrences...

BACKGROUND: Decision support tools build upon comprehensive and timely syntheses of literature. Rapid reviews may allow supporting their development by omitting certain components of traditional systematic reviews. We thus aimed to describe a rapid review approach underlying the development of decision support tools, i.e., five decision boxes (DB) for shared decision-making between seniors living with dementia, their caregivers, and healthcare providers. METHOD: We included studies based on PICO questions (Participant, Intervention, Comparison, Outcome) describing each of the five specific decision...

PURPOSE: An estimated 19 million children are visually impaired; of these, 1.4 million are irreversibly blind. A key challenge is to identify them early in life to benefit maximally from visual rehabilitation, and/or treatment. This aggregative review and structured literature analysis summarizes evidence of what it is about the key informant (KI) approach that works to identify children with blindness or severe visual impairment (B/SVI) in the community (for whom, to what extent, in what circumstances, in what respect, how and why)...

BACKGROUND: North American clinicians are increasingly participating in medical service trips (MSTs) that provide primary healthcare in Latin America and the Caribbean. Literature reviews have shown that the existence and use of evidence-based guidelines by these groups are limited, which presents potential for harm. OBJECTIVE: This paper proposes a 5-step methodology to develop protocols for diagnosis and treatment of conditions encountered by MST clinicians. METHODS: We reviewed the 2010 American College of Physicians guidance statement on guidelines development and developed our own adaptation...

BACKGROUND: Investing in research that is not accessible or used is a waste of resources and an injustice to human subject participants. Post-graduate students' research in institutions of higher learning involves considerable time, effort and money, warranting evaluation of the return on investment. Although individual studies addressing research productivity of post-graduate students are available, a synthesis of these results in low-income settings has not been undertaken. Our first aim is to identify the types of approaches that increase productivity and those that increase the application of medical post-graduate students' research and to assess their effectiveness...

BACKGROUND: Functional dyspepsia (FD or non-ulcer dyspepsia) is defined as continuous or frequently recurring epigastric pain or discomfort for which no organic cause can be found. Acid suppressive therapy, including proton pump inhibitors (PPIs), has been proposed as a therapeutic option in FD, but its efficacy remains controversial. While PPIs are generally considered safe and well tolerated, they have been associated with adverse events, especially in the long term. For this reason, decisions on whether to initiate or continue PPI therapy should be made based on an appropriate clinical indication...
