BACKGROUND: Taller height is associated with greater risk of venous thromboembolism (VTE). OBJECTIVES: We used instrumental variable (IV) techniques (Mendelian randomization) to further explore this relationship METHODS: Participants of European ancestry were included from two cohort studies [Atherosclerosis Risk in Communities (ARIC) study and Cardiovascular Health Study (CHS)] and one case-control study [Mayo Clinic VTE Study (Mayo)]. We created two weighted genetic risk scores (GRS) for height; the full GRS included 668 single nucleotide polymorphisms (SNPs) from a previously published meta-analysis and the restricted GRS included a subset of 362 SNPs not associated with weight independently of height...

REVIEW
Rudolf N Cardinal
BACKGROUND: Electronic medical records contain information of value for research, but contain identifiable and often highly sensitive confidential information. Patient-identifiable information cannot in general be shared outside clinical care teams without explicit consent, but anonymisation/de-identification allows research uses of clinical data without explicit consent. RESULTS: This article presents CRATE (Clinical Records Anonymisation and Text Extraction), an open-source software system with separable functions: (1) it anonymises or de-identifies arbitrary relational databases, with sensitivity and precision similar to previous comparable systems; (2) it uses public secure cryptographic methods to map patient identifiers to research identifiers (pseudonyms); (3) it connects relational databases to external tools for natural language processing; (4) it provides a web front end for research and administrative functions; and (5) it supports a specific model through which patients may consent to be contacted about research...

Tolyporphins are tetrapyrrole macrocycles produced by a cyanobacterium-containing culture known as HT-58-2. Tolyporphins A-J are free base dioxobacteriochlorins whereas tolyporphin K is an oxochlorin. Here, the photophysical characterization is reported of tolyporphin A and two synthetic analogues, an oxobacteriochlorin and a dioxobacteriochlorin. The characterization (in toluene, diethyl ether, ethyl acetate, dichloromethane, 1-pentanol, 2-butanone, ethanol, methanol, N,N-dimethylformamide, and dimethylsulfoxide) includes static absorption and fluorescence spectra, fluorescence quantum yields, and time-resolved data...

BACKGROUND CONTEXT: Severe adolescent idiopathic scoliosis (AIS) is a 3D spinal deformity requiring surgery to stop curve progression. Posterior spinal instrumentation and fusion with pedicle screws is the standard surgery for AIS curve correction. Vascular and neurologic complications related to screw-malpositioning are concerns in surgeries for AIS. Breach rates are reported at 15.7%, implant-related complications at 1.1% and neurologic deficit at 0.8%. Free-hand screw insertion remains the prevailing method of screw placement while image guidance has been suggested to improve placement accuracy...

Every U.S. student is entitled to a free and appropriate education. School districts must identify and evaluate any child who they find is unable to engage fully in learning as a participant in the general education curriculum. The Individuals with Disabilities Education Act of 2004 requires that these students be assessed by qualified individuals in any areas that may be impacting learning, including health, vision, hearing, social and emotional status, communicative status, and motor abilities. The school nurse, as the health expert, has an important role to play as a member of the special education team in evaluating whether a student has health concerns that are impacting learning and how health barriers to learning might be reduced...

Control of biofouling on seawater reverse osmosis (SWRO) membranes is a major challenge as treatments can be expensive, damage the membrane material and often biocides do not remove the polymers in which bacteria are embedded. Biological control has been largely ignored for biofouling control. The objective of this study was to demonstrate the effectiveness of xanthine oxidase enzyme against complex fouling communities and then identify naturally occurring bacterial strains that produce the free radical generating enzyme...

In Nepal, full-fledged environmental legislation was rare before the democratic constitution of 1990. The first law covering the environment and sustainability was the Environment Protection Act 1997. While the Solid Waste Act was introduced in 1987, the problem of solid waste management still surfaces in Kathmandu. In order to understand the bedrock of this unrelenting failure in solid waste management, the manuscript digs deeper into policy implementation by dissecting solid waste rules, environmental legislations, relevant local laws, and solid waste management practices in Kathmandu, Nepal...

BACKGROUND: Inferior pedicle and free nipple grafting are commonly used as breast reduction techniques for patients with breast hypertrophy and gigantomastia. Limitations of these techniques are, respectively, possible vascular compromise and total/partial necrosis of the nipple-areola complex (NAC). The authors describe the innovative inferocentral pedicled reduction mammaplasty (ICPBR) enhanced by preservation of Würinger's septum for severe hypertrophic breasts. MATERIALS AND METHODS: Among 287 breast reductions performed between January 2001 and 2015, 83 (28...

Ricardo Castillo-Neyra, Michael Z Levy, Cesar Náquira
In the Peruvian city of Arequipa, rabid dogs have been detected since March 2015, signaling the reintroduction of the rabies virus (RV) in this previously officially-declared rabies free zone. High dog density is considered one of the causes for the continuous transmission of the RV in the outbreak in the city of Arequipa, which seemingly lends support to the culling of dogs as a public health measure. However, the effectiveness of culling free-roaming dogs to control urban rabies has not been evaluated. Objective to determine the effectiveness of free-roaming dog culling as a control measure of urban rabies...

PURPOSE: During magnetic resonance (MR)-guided thermal therapies, water proton resonance frequency shift (PRFS) based MR temperature imaging can quantitatively monitor tissue temperature changes. It is widely known that the PRFS technique is easily perturbed by tissue motion, tissue susceptibility changes, magnetic field drift, and modality-dependent applicator induced artifacts. Here a referenceless Gaussian process modeling (GPM) based estimation of the PRFS is investigated as a methodology to mitigate unwanted background field changes...

Symptom management is one of the essential functions of nurses in inpatient settings; yet, little is understood about the manner in which nurses use electronic health records for symptom documentation. Therefore, the purpose of this systematic review is to characterize nurses' use of electronic health records for documentation of symptom assessment and management in inpatient settings, to inform design studies that better support electronic health records for patient symptom management by nurses. We searched the Ovid Medline (1946-current), Cumulative Index to Nursing and Allied Health Literature (EBSCO, 1981-current), and Excerpta Medica Database (Embase...

In this article we develop a lung-ventilation model. The parenchyma is described as an elastic homogenized media. It is irrigated by a space-filling dyadic resistive pipe network, which represents the tracheo-bronchial tree. In this model the tree and the parenchyma are strongly coupled. The tree induces an extra viscous term in the system constitutive relation, which leads, in the finite element framework, to a full matrix. We consider an efficient algorithm that takes advantage of the tree structure to enable a fast matrix-vector product computation...
