Importance: Collection and analysis of up-to-date and accurate injury surveillance data are a key step in the maturation of trauma systems. Trauma registries have proven to be difficult to establish in low- and middle-income countries owing to the burden of trauma volume, cost, and complexity. Objective: To determine whether an electronic trauma health record (eTHR) used by physicians can serve as simultaneous clinical documentation and data acquisition tools. Design, Setting, and Participants: This 2-part quality improvement study included (1) preimplementation and postimplementation eTHR study with assessments of satisfaction by 41 trauma physicians, time to completion, and quality of data collected comparing paper and electronic charting; and (2) prospective ecologic study describing the burden of trauma seen at a Level I trauma center, using real-time data collected by the eTHR on consecutive patients during a 12-month study period...

BACKGROUND: Women with STEMI receive suboptimal care and have worse outcomes than men. Whether strategies to reduce STEMI care variability impact disparities in the care and outcomes of women with STEMI is unknown. OBJECTIVES: We assessed the care and outcomes of men vs. women with STEMI before and after implementation of a comprehensive STEMI protocol. METHODS: On 7/15/14 we implemented: (1) emergency department catheterization lab activation, (2) STEMI Safe Handoff Checklist, (3) immediate transfer to an immediately available catheterization lab, and (4) radial first approach to percutaneous coronary intervention (PCI)...

BACKGROUND: Rapid Response Teams (RRTs) are groups of healthcare providers that are used by many hospitals to respond to acutely deteriorating patients admitted to the wards. We sought to identify outcomes of patients assessed by RRTs outside standard working hours. METHODS: We used a prospectively collected registry from two hospitals within a single tertiary care-level hospital system between May 1, 2012, and May 31, 2016. Patient information, outcomes, and RRT activation information were stored in the hospital data warehouse...

BACKGROUND: The distribution of trauma deaths was classically described as trimodal. With advances in both technology and trauma systems, this was re-evaluated and found to be bimodal in the early 2000s. Over the last decade there have been continued improvements in trauma and ICU care, related to damage control techniques and evidence based ICU pathways. A better understanding of the distribution of trauma deaths may be used to improve trauma systems. This study aimed to evaluate the contemporary distribution of trauma deaths after the widespread implementation of modern trauma and critical care principles...

Accurately predicting protein-ligand binding affinities and binding modes is a major goal in computational chemistry, but even the prediction of ligand binding modes in proteins poses major challenges. Here, we focus on solving the binding mode prediction problem for rigid fragments. That is, we focus on computing the dominant placement, conformation, and orientations of a relatively rigid, fragment-like ligand in a receptor, and the populations of the multiple binding modes which may be relevant. This problem is important in its own right, but is even more timely given the recent success of alchemical free energy calculations...

Dopamine is a neurotransmitter that modulates arousal and motivation in humans and animals. It plays a central role in the brain "reward" system. Its dysregulation is involved in several debilitating disorders such as addiction, depression, Parkinson's disease, and schizophrenia. Dopamine neurotransmission and its reuptake in extracellular space takes place with millisecond temporal and nanometer spatial resolution. Novel nanoscale electrodes are needed with superior sensitivity and improved spatial resolution to gain improved understanding of dopamine dysregulation...

Fluorescence correlation spectroscopy (FCS) is a powerful tool to quantitatively study the diffusion of fluorescently labeled molecules. It allows in principle important questions of macromolecular transport and supramolecular aggregation in living cells to be addressed. However, the crowded environment inside the cells slows diffusion and limits the reservoir of labeled molecules, causing artifacts that arise especially from photobleaching and limit the utility of FCS in these applications. We present a method to compute the time correlation function from weighted photon arrival times, which compensates computationally during the data analysis for the effect of photobleaching...

BACKGROUND: Currently, treatment of latent tuberculosis infection (LTBI) in Australia consists most commonly of a 9-month course of isoniazid (9H). A 3-month course of weekly isoniazid and rifapentine (3HP) has been shown to be as effective as 9 months of daily isoniazid, and associated with less hepatotoxicity; however, rifapentine is not currently available in Australia. Introduction of this regimen would have apparent advantages for people with LTBI in Victoria by safely shortening duration of LTBI therapy...

Visual impairment associated with Age-related Macular Degeneration (AMD) often results in a central scotoma which is an alteration in the central vision, leading to distortion or loss of vision. Current methods for assessing visual performance such as Amsler grid and Microperimetry are typically manual and have limitations as an indicator of visual field. In this paper, we present an automated system for detecting visual impairment through gaze tracking (AVIGA). Two types of assessments namely, Impulse Stimuli Response (ISR) test and Pursuit Stimuli Response (PSR) test were implemented in AVIGA system...

The primary objective of this study was to develop lipid-based self-microemulsifying drug delivery systems (SMEDDS) without using any organic cosolvents that would spontaneously form microemulsions upon dilution with water. Cosolvents were avoided to prevent possible precipitation of drug upon dilution and other stability issues. Different polysorbates, namely, Tween 20, Tween 40, Tween 60, and Tween 80, were used as surfactants, and Captex 355 EP/NF (glycerol tricaprylate/caprate) or its 1:1 mixture with Capmul MCM NF (glycerol monocaprylocaprate) were used as lipids...

Methamphetamine (MAMP) is a popular illicit drug abused for its central nervous system stimulating effects. MAMP is also used therapeutically in the treatment of overeating disorders, narcolepsy, attention deficit disorder, in over-the-counter (OTC) products to ease nasal congestion. MAMP exists in two enantiomeric forms, dextrorotary (d-MAMP) or levorotary (l-MAMP). The compounds are similar in chemical structure, simply differing in the orientation of functional groups around the asymmetric carbon. In part because of the availability of l-MAMP in OTC nasal inhalers, forensic guidelines require a sample to contain greater than 20% d-MAMP to consider illicit drug use when interpreting results...

High arsenic (As) concentrations in the soil, water and plant systems can pose a direct health risk to humans and ecosystems. Phosphate (Pi) ions strongly influence As availability in soil, its uptake and toxicity to plants. Better understanding of As(V)-Pi interactions in soils and plants will facilitate a potential remediation strategy for As contaminated soils, reducing As uptake by crop plants and toxicity to human populations via manipulation of soil Pi content. However, the As(V)-Pi interactions in soil-plant systems are complex, leading to contradictory findings among different studies...
