BACKGROUND: Studies on diagnostic tests for exercise-induced bronchoconstriction (EIB) have centered around the asthmatic and elite athletic population. Traditionally, the exercise challenge test (ET) was recommended to assess EIB. We aimed to compare the performance of surrogate testing, mainly the hypertonic saline (HS) test, and methacholine challenge test (MCT) versus ET in identifying EIB among non-athletic subjects. METHODS: We prospectively recruited subjects who did not have confirmed active asthma, but who reported exercise-induced dyspnoea...

RATIONALE, AIMS, OBJECTIVES: Clinical Practice Guidelines are mostly developed by 3 methods; namely, de novo, adoption, and adaptation. Nonpublished studies and authors experience shows that most guidelines in Turkey are either by adoption or by adaptation. There is no available local tool for adaptation, so the process is not standardized and most of the time not explicitly defined. The objective of this study is to search for international guideline adaptation tools and test their feasibility in Turkish context, to serve a final goal of developing a unique local strategic tool for guideline adaptation...

AIM: Chromosomal microarray (CMA) is an important diagnostic test for children with multiple congenital anomalies or certain developmental behavioural problems suggestive of an underlying genetic diagnosis. However, there are medical and ethical complexities to its use and few Australian policies to guide practice. We aimed to describe the current practice of Australian paediatricians in relation to CMA testing. We hypothesised that there are knowledge gaps in their use of CMA. METHODS: Online survey completed between September 2015 and January 2016 by paediatricians in secondary care settings...

A growing body of literature seeks to explain variation in range shifts using species' ecological and life history traits, with expectations that shifts should be greater in species with greater dispersal ability, reproductive potential, and ecological generalization. Despite strong theoretical support for species' traits as predictors of range shifts, empirical evidence from contemporary range shift studies remains limited in extent and consensus. We conducted the first comprehensive review of species' traits as predictors of range shifts, collecting results from 51 studies across multiple taxa encompassing over 11,000 species' responses for 54 assemblages of taxonomically-related species occurring together in space...

A new macro-Raman system equipped with a motorized translational sample stage and low-frequency shift capabilities was developed for bulk composition and homogeneity analysis of multi-component pharmaceutical powders. Different sampling methods including single spot and scanning measurement were compared. It was found that increasing sample volumes significantly improved the precision of quantitative composition analysis, especially for poorly mixed powders. The multi-pass cavity of the macro-Raman system increased effective sample volumes by 20 times from the sample volume defined by the collection optics, i...

#11
Tessel Boerma, Elma Blom
Language delays of bilingual children can arise from language impairment (LI) but also from insufficient exposure to the target language. A reliable diagnosis of LI in bilingual children is therefore ideally based on the evaluation of both languages, as LI affects each language that is learned. However, due to the multitude of language combinations that are encountered in clinical practice, this is often not feasible. Bilingual norm-referencing may offer a solution, but the heterogeneity within the bilingual population makes it difficult to determine appropriate standards for every child...

Identifying, understanding, and curing disease is a lifelong endeavor for any medical practitioner. Equally as important is to be cognizant of the impact a disease has on the individual suffering from it, as well as on their family. Ovarian cancer is the leading cause of death from gynecologic malignancies. Symptoms are vague, and the disease is generally at an advanced stage at diagnosis. Efforts have been made to develop methods to identify ovarian cancer at earlier stages, thus improving overall mortality...

The MolecuLight i:X Imaging Device is a portable, noninvasive, real-time camera used to visualize the bacterial load in a wound. It uses violet light illumination and a dual bandpass optical filter to capture the fluorescence of endogenous structures in the tissue matrix and harmful bacteria. The MolecuLight i:X captures images of wounds and highlights potentially detrimental levels of bacteria. This is an initial evaluation of using the MolecuLight i:X camera in the management of burns to demonstrate the following: the ability of the device to guide clinicians in their management of the burn (ie, detect, identify, and specify swabbing locations)...

OBJECTIVE: Although numerous research studies have reported high levels of error and misuse of child restraint systems (CRS) and booster seats in experimental and real world scenarios, conclusions are limited because they provide little information regarding which installation issues pose the highest risk and thus should be targeted for change. Beneficial to legislating bodies and researchers alike would be a standardized, globally relevant, assessment of the potential injury risk associated with more common forms of CRS and booster seat misuse, which could be applied with observed error frequency, for example, in car seat clinics or during prototype user testing, to better identify and characterize the installation issues of greatest risk to safety...

One of the limiting steps to detecting traces of explosives at screening venues is effective collection of the sample. Wipe-sampling is the most common procedure for collecting traces of explosives, and standardized measurements of collection efficiency are needed to evaluate and optimize sampling protocols. The approach described here is designed to provide this measurement infrastructure, and controls most of the factors known to be relevant to wipe-sampling. Three critical factors (the applied force, travel distance, and travel speed) are controlled using an automated device...
