PURPOSE: To assess the feasibility of 3D oxygen-enhanced (OE) MRI of the lung at 1.5T using multi-volumetric ultra-fast balanced steady-state free precession (ufSSFP) acquisitions. METHODS: Isotropic imaging of the lung for OE-MRI was performed with an adapted 3D ufSSFP sequence using five breath-hold acquisitions ranging from functional residual capacity to tidal inspiration under both normoxic (room air) and hyperoxic (100% O2 ) gas conditions. For each O2 concentration, a sponge model (which captures the parenchymal signal intensity variation as a function of the lung volume) was fitted to the acquired multi-volumetric datasets after semiautomatic lung segmentation and deformable image registration...

The aim of this study was to investigate whether neighborhood walkability moderates the association between low back pain (LBP) and physical activity (PA), using a co-twin design to control for genetics and shared environmental factors. A cross-sectional analysis was performed on 10,228 twins from the Washington State Twin Registry with available data on LBP from recruitment surveys between 2009 and 2013. LBP within the past 3months was our exposure variable. Our outcome variables were sufficient moderate or vigorous-intensity PA (MVPA, defined as at least 75min of vigorous-intensity PA, or 150min of moderate-intensity PA per week), and walking (≥150min per week)...

Hanley, Jin, Vanselow, and Hanratty (2014) described a functional analysis (FA) format that relied on a synthesis of multiple contingencies described by caregivers during open-ended interviews. These interview-informed synthesized contingency analyses (IISCA) provided effective baselines from which to develop socially validated treatments, but the synthesis precluded a precise understanding of individual contingencies influencing problem behavior. We conducted IISCAs and standard FAs (Iwata, Dorsey, Slifer, Bauman, & Richman, 1982/1994) for nine children with autism to evaluate the likelihood of differentiation given a number of synthesized versus isolated variables...

The main dissipation mechanism in superconducting nanowires arises from phase slips. Thus far, most of the studies focus on long nanowires where coexisting events appear randomly along the nanowire. In the present work we investigate highly confined phase slips at the contact point of two superconducting leads. Profiting from the high current crowding at this spot, we are able to shrink in-situ the nanoconstriction. This procedure allows us to investigate, in the very same sample, thermally activated phase slips and the probability density function of the switching current Isw needed to trigger an avalanche of events...

High among the challenges facing mankind as the world population rapidly expands toward 9 billion people by 2050 is the technological development and implementation of sustainable agriculture and food systems to supply abundant and wholesome nutrition. In many low-income societies, women and children are the most vulnerable to food insecurity, and it is unequivocal that quality nutrition during the first 1000 d of life postconception can be transformative in establishing a robust, lifelong developmental trajectory...

Purpose Men with localized prostate cancer often are treated with external radiotherapy (RT) over 8 to 9 weeks. Hypofractionated RT is given over a shorter time with larger doses per treatment than standard RT. We hypothesized that hypofractionation versus conventional fractionation is similar in efficacy without increased toxicity. Patients and Methods We conducted a multicenter randomized noninferiority trial in intermediate-risk prostate cancer (T1 to 2a, Gleason score ≤ 6, and prostate-specific antigen [PSA] 10...

Bacterial adherence to extracellular matrix proteins (ECMp) plays important roles during host-pathogen interaction, however its genetic regulation remains poorly understood. yloA of the model bacterium Bacillus subtilis shows high homology to genes encoding fibronectin-binding proteins of Gram-positive pathogens. Here, we characterized the regulatory network of YloA-dependent adhesive properties of the probiotic B. subtilis natto (Bsn). YloA-proficient, but not YloA-deficient, Bsn specifically bound to ECMp in a concentration-dependent manner and were proficient in biofilm formation...

of the present work was assessment of possibility to use modern electroimpedace methods for the study of activity of the heart. Electroimpemdace methods of measurement for many years remained in the shadow of other diagnostic methods because of low accuracy in evaluation of various parameters. At present, there are technologies of measurement which allow to carry out electroimpedance investigations of cardiac activity dynamically and with acceptable accuracy. In this article, we present methods of electroimpedace measurements created in Institute of Biomedical Equipment of N...

The use of electronic cigarettes has become increasingly popular with claims suggesting healthier alternatives to tobacco cigarettes. However, research regarding the safety of such devices has been limited to an analysis of the inhaled vapor and the short and long-term effects on the body. A lesser recognized risk of electronic cigarette use is that of lithium-ion battery failure causing ignition, leading to severe thermal injury. Such incidents have been reported in the media but with inconsistencies from a lack of focus on the injuries sustained and a cause of ignition...

Issue addressed: Only half of Australia's adult population is sufficiently physical active. One method thought to increase incidental physical activity at work is the use of stair-promoting interventions. Stairs are readily available and stair climbing is considered vigorous physical activity. Motivational signs have been extensively and effectively trialled to increase stair use, but are they suitable for contemporary populations? Methods: Participants were occupants of three selected University of Sydney buildings using the elevators or stairs...

BACKGROUND: Fruit and vegetable (F&V) consumption is below recommendations, and cost may be a barrier to meeting recommendations. Limited evidence exists on individual perceptions about the cost, actual spending and consumption of F&V. This study investigated perceptions and beliefs about cost of F&V and whether this is a barrier to higher consumption. METHODS: An online survey of Australian adults (n = 2474) measured F&V consumption; expenditure on F&V and food; and perceived barriers to consumption...

OBJECTIVE: We proposed and tested a theoretical framework for how use of Teach-back could influence communication during the pediatric clinical encounter. METHODS: Audio-taped pediatric primary care encounters with 44 children with asthma were coded using the Roter Interaction Analysis System to measure patient-centered communication and affective engagement of the parent. A newly created Teach-back Loop Score measured the extent to which Teach-back occurred during the clinical encounter; parental health literacy was measured by Newest Vital Sign...

BACKGROUND: There is a paucity of intervention studies assessing active travel to school as a mechanism to increase physical activity. This paper describes the impact of a community-wide intervention on active travel to primary schools in two Irish towns. METHODS: This was a repeat cross-sectional study of a natural experiment. Self-report questionnaires were completed by 5(th) and 6(th) grade students in three towns (n = 1038 students in two intervention towns; n = 419 students in one control town) at baseline and by a new group of students two years later at follow-up...

There is often a disconnection between the creation of evidence and its use in policy and practice. Cross-sectoral, multidisciplinary partnership research, founded on shared governance and coproduction, is considered to be one of the most effective means of overcoming this research-policy-practice disconnect. Similar to a number of funding bodies internationally, Australia's National Health and Medical Research Council has introduced Partnership Centres for Better Health: a scheme explicitly designed to encourage coproduced partnership research...

Most cases of Van der Woude syndrome are caused by a mutation to interferon regulatory factor 6 on chromosome 1. Turner syndrome is caused by complete or partial absence of the second sex chromosome in girls. We describe a unique case of the two syndromes occurring concurrently though apparently independently in a girl with Van der Woude syndrome diagnosed at birth and Turner syndrome at 14 years 9 months. Short stature was initially misattributed to Van der Woude syndrome and pituitary insufficiency associated with clefts before correctly diagnosing Turner syndrome...
