RATIONALE: Supplemental oxygen is prescribed to patients with pulmonary fibrosis to normalize oxygen saturations, decrease symptoms and improve quality of life. Along with potential benefits, patients face challenges as they incorporate oxygen into their lives. OBJECTIVE: Our aim was to better understand the perceptions and experiences of patients with pulmonary fibrosis as they confronted the possibility and realities of using supplemental oxygen. METHODS: We performed a mixed-methods study in which we conducted a series of four structured telephone interviews with five patients with pulmonary fibrosis enrolled in a longitudinal observational study...

BACKGROUND AND OBJECTIVES: In order to achieve a high degree of visual realism in surgery simulation, we propose a new model, which is based on point primitives and continuous elastic mechanics theory, for soft tissue deformation, tearing and/or cutting. METHODS: The model can be described as a two-step local high-resolution strategy. First, appropriate volumetric data are sampled and assigned with proper physical properties. Second, sparsely sampled points in non-deformed regions and densely-sampled points in the deformed zone are selected and evaluated...

BACKGROUND: Step width is increased during dual-belt treadmill walking, in self-paced mode with virtual reality. Generally a familiarization period is thought to be necessary to normalize step width. AIM: The aim of this randomised study was to analyze the effects of two interventions on step width, to reduce the familiarization period. METHODS: We used the GRAIL (Gait Real-time Analysis Interactive Lab), a dual-belt treadmill with virtual reality in the self-paced mode...

OBJECTIVE: The paper evaluates the application of a mixed reality (MR) headmounted display (HMD) for the visualization of anatomical structures in complex visceral-surgical interventions. A workflow was developed and technical feasibility was evaluated. SUMMARY OF BACKGROUND DATA: Medical images are still not seamlessly integrated into surgical interventions and, thus, remain separated from the surgical procedure.Surgeons need to cognitively relate 2-dimensional sectional images to the 3-dimensional (3D) during the actual intervention...

New challenges have been brought out along with the emerging of 3D-related technologies such as virtual reality (VR), augmented reality (AR), and mixed reality (MR). Free viewpoint video (FVV), due to its applications in remote surveillance, remote education, etc, based on the flexible selection of direction and viewpoint, has been perceived as the development direction of next-generation video technologies and has drawn a wide range of researchers' attention. Since FVV images are synthesized via a depth image-based rendering (DIBR) procedure in the "blind" environment (without reference images), a reliable real-time blind quality evaluation and monitoring system is urgently required...

Increasing evidence has shown that genes may cause prenatal, neonatal, and pediatric diseases depending on their parental origins. Statistical models that incorporate parent-of-origin effects (POEs) can improve the power of detecting disease-associated genes and help explain the missing heritability of diseases. In many studies, children have been sequenced for genome-wide association testing. But it may become unaffordable to sequence their parents and evaluate POEs. Motivated by the reality, we proposed a budget-friendly study design of sequencing children and only genotyping their parents through single nucleotide polymorphism array...

BACKGROUND: While farming in France and generally in Europe is continuing to intensify, at the expense of its environmental sustainability, promising alternatives are emerging. OBJECTIVE: The processes whereby farmers change and transform their own work, to shift from an intensive mode of production to a self-sufficient and autonomous one, need to be formalized if we are to further our understanding of why and how these forms of sustainable farming activity emerge...

A mixed design was created using text and game-like multimedia to instruct in the content of physics. The study assessed which variables predicted learning gains after a 1-h lesson on the electric field. The three manipulated variables were: (1) level of embodiment; (2) level of active generativity; and (3) presence of story narrative. Two types of tests were administered: (1) a traditional text-based physics test answered with a keyboard; and (2) a more embodied, transfer test using the Wacom large tablet where learners could use gestures (long swipes) to create vectors and answers...

Chronic hepatitis C virus (HCV) infection is burdensome in patients with chronic kidney disease and contributes to substantial liver-related and all-cause morbidity and mortality. HCV infection itself may cause kidney dysfunction, as exemplified through mixed cryoglobulinemic vasculitis. HCV is more prevalent in patients with significant kidney disease compared to the general population, and recent reports have shown inadvertent HCV transmission in U.S. hemodialysis centers. Further, HCV has been demonstrated to accelerate kidney dysfunction and is associated with worse clinical outcomes in patients with kidney disease...

The average primary care psychologist feels an ever-widening gap between objective, measurable reality as described and the complex and dynamic reality they experience. To obtain a better understanding of this complex dynamic reality, we conducted an exploratory mixed-method study of primary care psychologists. We asked our participants to write vignettes about messy and confusing problems in the complex context of mental healthcare. We then examined the data in portions, exposed the patterns in the data, and subsequently analysed all in conjunction...

Until recently, the literature that addressed the phenomenon of mixed-orientation relationships, in which the female partner is straight and the male partner is non-straight, has focused mainly on the men's perspective. Most of the studies have employed a pessimistic tone, underscoring the obstacles faced by each of the spouses. This study was designed to understand how women of mixed-orientation relationships construct their reality within such a relationship, focusing on elements which assist them in maintaining those relationships...

Campylobacter contamination of chicken on sale in the UK remains at high levels and has a substantial public health impact. This has prompted the application of many interventions in the supply chain, including enhanced biosecurity measures on-farm. Catching and thinning are acknowledged as threats to the maintenance of good biosecurity, yet the people employed to undertake this critical work (i.e. 'catchers') are a rarely studied group. This study uses a mixed methods approach to investigate catchers' (n=53) understanding of the biosecurity threats posed by the catching and thinning, and the barriers to good biosecurity practice...

Despite the medical advancements in HIV treatment, realities of side effects are faced by people living with HIV (PLWH) who receive antiretroviral therapy (ART). Mixed findings have been reported on the association between side effects and ART adherence. However, few studies have explored the combined side effects and behavior-related information on medication adherence. The aim of the current study is to examine moderator role of ART-related knowledge between side effects and ART adherence. A cross-sectional survey was conducted among 2987 PLWH from October 2012 to August 2013 in China...
