Introduction Following two decades of armed conflict in Liberia, over 95% of health care facilities were partially or completely destroyed. Although the Liberian health system has undergone significant rehabilitation, one particular weakness is the lack of organized systems for referral and prehospital care. Acute care referral systems are a critical component of effective health care delivery and have led to improved quality of care and patient outcomes. Problem This study aimed to characterize the referral and transfer systems in the largest county of Liberia...

The Pig-a assay is being developed as an in vivo gene mutation assay for regulatory safety assessments. The assay is based on detecting mutation in the endogenous Pig-a gene of treated rats by using flow cytometry to measure changes in cell surface markers of peripheral blood cells. Here we present a methodology for demonstrating that phenotypically mutant rat T-cells identified by flow cytometry contain mutations in the Pig-a gene, an important step for validating the assay. In our approach, the mutant phenotype T-cells are sorted into individual wells of 96-well plates and expanded into clones...

The visual system must recover important properties of the external environment if its host is to survive. Because the retinae are effectively twodimensional but the world is three-dimensional (3D), the patterns of stimulation both within and across the eyes must be used to infer the distal stimulus-the environment-in all three dimensions. Moreover, animals and elements in the environment move, which means the input contains rich temporal information. Here, in addition to reviewing the literature, we discuss how and why prior work has focused on purported isolated systems (e...

Ethiopia is one of the few African countries where Plasmodium vivax is co-endemic with P. falciparum. Malaria transmission is seasonal and transmission intensity varies mainly by landscape and climate. Although the recent emergence of drug resistant parasites presents a major issue to malaria control in Ethiopia, little is known about the transmission pathways of parasite species and prevalence of resistant markers. This study used microsatellites to determine population diversity and gene flow patterns of P...

PURPOSE: To measure the Reynolds stress tensor using 4D flow MRI, and to evaluate its contribution to computed pressure maps. METHODS: A method to assess both velocity and Reynolds stress using 4D flow MRI is presented and evaluated. The Reynolds stress is compared by cross-sectional integrals of the Reynolds stress invariants. Pressure maps are computed using the pressure Poisson equation-both including and neglecting the Reynolds stress. RESULT: Good agreement is seen for Reynolds stress between computational fluid dynamics, simulated MRI, and MRI experiment...

Sleep onset is characterized by a specific and orchestrated pattern of frequency and topographical EEG changes. Conventional power analyses of electroencephalographic (EEG) and computational assessments of network dynamics have described an earlier synchronization of the centrofrontal areas rhythms and a spread of synchronizing signals from associative prefrontal to posterior areas. Here, we assess how "small world" characteristics of the brain networks, as reflected in the EEG rhythms, are modified in the wakefulness-sleep transition comparing the pre- and post-sleep onset epochs...

INTRODUCTION: Dental caries is defined as a pathological breakdown of the tooth. It is an infectious phenomenon involving a multifactorial aetiology. The impact of drugs on cariogenic risk has been poorly investigated. OBJECTIVES: In this study, we identified drugs suspected to induce dental caries as adverse drug reactions (ADRs) and then studied a possible pathogenic mechanism for each drug that had a statistically significant disproportionality. METHODS: We extracted individual case safety reports of dental caries associated with drugs from VigiBase(®) (the World Health Organization global individual case safety report database)...

This study aims to investigate the capability of smoothed particle hydrodynamics (SPH), a fully Lagrangian mesh-free method, to simulate the bulk blood flow dynamics in two realistic left ventricular (LV) models. Three dimensional geometries and motion of the LV, proximal left atrium and aortic root are extracted from cardiac magnetic resonance imaging and multi-slice computed tomography imaging data. SPH simulation results are analyzed and compared with those obtained using a traditional finite volume-based numerical method, and to in vivo phase contrast magnetic resonance imaging and echocardiography data, in terms of the large-scale blood flow phenomena usually clinically measured...

Carmen B Schäfer, Freek E Hoebeek
To safely maneuver through the environment the brain needs to compare active sensory information with ongoing motor programs. This process occurs at various levels in the brain: at the lower level, i.e. in the spinal cord, reflexes are generated for the most primitive motor responses; at the intermediate level, i.e., in the brainstem, various nuclei co-process sensory- and motor-related inputs; and, at the higher level cerebellum and thalamo-cortical networks individually compute suitable commands for fine-tuned motor output...

OBJECTIVES: Light chains κ and λ are immunoglobulin constituents but also circulate independently in blood as free light chains. We investigated whether a concomitant abnormality in free light chain and immunoglobulin levels could identify a high risk of death sepsis subpopulation to inform future IV immunoglobulin trials. We tested whether light chain allelic inclusion occurs in circulating B cells. DESIGN: Prospective cohort study. SETTING: Adult general ICUs...

OBJECTIVE: Echocardiography is the most important tool to assess infants with congenital diaphragmatic hernia (CDH) for pulmonary hypertension (PH). The pattern of blood flow in the pulmonary artery [described as time to peak velocity (TPV)/right ventricular ejection time (RVET) ratio] provides distinct information about pulmonary arterial pressure. The aim of our study was to investigate the correlation of TPV/RVET measurements with the most commonly used classification system for PH in CDH newborns and the association of these measurements with outcome parameters...

OBJECTIVE: The diagnostic radiology process represents a partnership between clinical and radiology teams. As such, breakdowns in interpersonal interactions and communication can result in patient harm. CONCLUSION: We explore the role of radiology in the diagnostic process, focusing on key concepts of information and communication, as well as key interpersonal interactions of teamwork, collaboration, and collegiality, all based on trust. We propose 10 principles to facilitate effective information flow in the diagnostic process...

Monitoring cardiovascular signals such as heart rate and blood flow provides critically important healthcare information about patients under medical care. However, when the sensors are worn for extended times, the sensors sometimes require higher mechanical compatibility with soft deformable tissues. In this paper, we report an attachable and flexible pulse sensor (bending radius: 2.4 mm), integrated with micro-inorganic photodetectors (thickness: 4.1 μm, photocurrent: 8.99 μA under 1.5 mW/cm(2)) and a red light emitting diode (620 nm), to monitor vital signals for extended times...

This paper provides technical details and user guidance on the Research Infrastructure of Chinese Foundations (RICF), a database of Chinese foundations, civil society, and social development in general. The structure of the RICF is deliberately designed and normalized according to the Three Normal Forms. The database schema consists of three major themes: foundations' basic organizational profile (i.e., basic profile, board member, supervisor, staff, and related party tables), program information (i.e., program information, major program, program relationship, and major recipient tables), and financial information (i...

For extending the dynamic range of video, it is a common practice to capture multiple frames sequentially with different exposures and combine them to extend the dynamic range of each video frame. However, this approach results in typical ghosting artifacts due to fast and complex motion in nature. As an alternative, video imaging with interlaced exposures has been introduced to extend the dynamic range. However, the interlaced approach has been hindered by jaggy artifacts and sensor noise, leading to concerns over image quality...

Challenge: Although lecturing is an efficient method for the dissemination of information, it has long been criticized for learner passivity and diminished knowledge retention. Active learning strategies to engage the audience in the learning process can facilitate a bidirectional flow of ideas and content between teacher and students during a lecture to keep learners engaged and participating.

BACKGROUND: In early 2016 the Partnership for Health IT Patient Safety released safe practice recommendations for the use of copy-paste for electronic health record (EHR) documentation. These recommendations do not directly address nurses' use of copy-forward to document patient assessments in flow sheet software in hospital settings. Similar to clinicians' use of copy-paste and copy-forward with progress notes, concerns exist about patient safety issues from the use of potential inaccurate or outdated information to achieve increased efficiency of documentation...
