BACKGROUND: Inclusion health focuses on people in extremely poor health due to poverty, marginalisation, and multimorbidity. We aimed to review morbidity and mortality data on four overlapping populations who experience considerable social exclusion: homeless populations, individuals with substance use disorders, sex workers, and imprisoned individuals. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, and the Cochrane Library for studies published between Jan 1, 2005, and Oct 1, 2015...

The groundwater irrigation expansion, and its multiple potential impacts on the quantity and quality of water resources, is not just restricted to areas that are water limited. In this study we present the seasonal impacts irrigation practices can have on groundwater resources in a temperate humid region, where the average annual rain/PET ratio is 1.0. In this system the irrigation expansion is solely supported by groundwater pumping, but despite this only 5 boreholes are monitored for hydraulic head data. In this study, we compensate the scarce hydrophysical dataset by incorporating environmental tracers (major ions, δ(18)O, δ(2)H and δ(13)C) and dating tracers ((3)H, CFC, SF6 and (14)C)...

What kinds of physical environments make for free societies? The present research investigates the effect of three different types of ecological stressors (climate stress, pathogen stress, and frontier topography) on two measurements of governmental restriction: Vertical restriction involves select persons imposing asymmetrical laws on others, while horizontal restriction involves laws that restrict most members of a society equally. Investigation 1 validates our measurements of vertical and horizontal restriction...

BACKGROUND: Craniofacial growth pattern has been correlated with variations in size of the upper airway spaces. The objective of this study was to evaluate the nasopharyngeal, oropharyngeal, and hypopharyngeal airway spaces variations according to the craniofacial growth pattern, by comparing brachyfacial, mesofacial, and dolichofacial in Angle Class I individuals. METHODS: To measure the spaces, 45 lateral teleradiographs were used and divided into 3 groups per the craniofacial growth pattern, determined by the Tweed cephalometry angular measurements: FMA and Y-axis...

We performed a retrospective matched case-control study evaluating whether the traditional coagulation profile predicts cerebrovascular events in children on extracorporeal membrane oxygenation (ECMO) in a 71 bed intensive care unit at a tertiary children's hospital. Between 2009 and 2014, 241 neonates and children were initiated on ECMO. The cumulative 5 year incidence of intracranial hemorrhage and infarct was 9.2% and 7.9%, respectively. Thirty-six cases were individually matched 1:1 with control subjects based on age, primary diagnosis, ECMO type, cannulation site, and the presence of pre-ECMO coagulopathy...

BACKGROUND: Clinicians making decisions require the ability to self-monitor and evaluate their certainty of being correct while being mindful of the potential consequences of alternative actions. For clinical students, this ability could be inferred from their responses to multiple-choice questions (MCQ) by recording their certainty in correctness and avoidance of options that are potentially unsafe. METHODS: Response certainty was assessed for fifth year medical students (n = 330) during a summative MCQ examination by having students indicate their certainty in each response they gave on the exam...

BACKGROUND: Learning algorithms come in three orders of complexity: zeroth-order (perturbation), first-order (gradient descent), and second-order (e.g., quasi-Newton). But which of these are used in the brain? We trained 12 people to shoot targets, and compared them to simulated subjects that learned the same task using various algorithms. RESULTS: Humans learned significantly faster than optimized zeroth-order algorithms, but slower than second-order ones. CONCLUSIONS: Human visuomotor learning is too fast to be explained by zeroth-order processes alone, and must involve first or second-order mechanisms...

The present study was conducted to evaluate the three-dimensional (3D) cephalometry accuracy of cone-beam computed tomography (CBCT). A total of 40 newly diagnosed orthodontic patients (including 18 males and 22 females; age range, 12-18 years) were subjected to CBCT scanning and X-ray imaging in order to obtain lateral cephalograms. The 3D CBCT cephalograms were reconstructed and measured with in vivo 5.1 software, and compared with the results from the conventional 2D lateral cephalograms. Measurements in the two images were performed twice using the Steiner and Tweed standards and a single analyzer paired t-test was used to analyze the differences between the two cephalometric methods...

Although the optimal ventilation strategy is unknown for patients placed on extracorporeal support, there are increasing reports of extubation being used. Our objective was to describe the change in ventilation strategies and use of tracheostomy and bronchoscopy practices among extracorporeal membrane oxygenation (ECMO) centers across the world. A descriptive, cross-sectional 22 item survey of neonatal, pediatric, and adult ECMO centers was used to evaluate ventilator strategies, extubation, bronchoscopy, and tracheostomy practices...

INTRODUCTION: 25% of patients with lung cancer have performance status 3 or 4. A pragmatic approach to investigative procedures is often adopted based on the risks and benefits in these patients and whether tissue diagnosis is necessary for anticipated future treatment. This cohort study investigated factors influencing a clinician's decision to pursue a tissue diagnosis in patients with lung cancer and performance status 3 and 4 and to examine the association of tissue diagnosis with subsequent management and survival...
