Introduction. This small pilot study aimed to examine the feasibility of an upper limb rehabilitation system (the YouGrabber) in a community rehabilitation centre, qualitatively explore participant experiences, and describe changes after using it. Methods and Material. Chronic stroke participants attending a community rehabilitation centre in the UK were randomised to either a YouGrabber or a gym group and completed 18 training sessions over 12 weeks. The motor activity log, box and block, and fatigue severity score were administered by a blinded assessor before and after the intervention...

A market research company (Nielsen) reported that consumers in the Asia-Pacific region have become the most active group in online shopping. Focusing on augmented reality (AR), which is one of three major techniques used to change the method of shopping in the future, this study used a mixed design to discuss the influences of the method of online shopping, user gender, cognitive style, product value, and sensory channel on mental workload in virtual reality (VR) and AR situations. The results showed that males' mental workloads were significantly higher than females'...

OBJECTIVES: Within their local realities, people experience and interpret disease in diverse ways that do not necessarily correlate or converge with Western biomedical interventions. In the high cervical cancer burden setting of Papua New Guinea, understanding how people experience and interpret cervical cancer is necessary for effective intervention. Drawing on work by Street on the production of unstable biomedical knowledge, we explored how ambiguity and uncertainty, coupled with cultural taboos and linguistic limitations, affect what and how people 'know' about women's reproductive organs and their associated disease...

Bo Chen, Alois M Herkommer
The most widely applied design form for mixed reality head-mounted display (HMD) systems is generally a prism with one surface in total internal reflection (TIR). This, however, limits the angle of the incident rays, and thus decreases the design freedom and affects the performance. To obtain better performance of the HMD optics, in this paper two seldom used design forms of HMD systems are presented and compared to the standard TIR HMD optics. One of them is a catadioptric HMD system, consisting of one lens and two mirrors; the other is a prism HMD with a different folding geometry...

BACKGROUND: Until recently, actigraphy studies in bipolar disorders focused on sleep rather than daytime activity in mania or depression, and have failed to analyse mixed episodes separately. Furthermore, even those studies that assessed activity parameters reported only mean levels rather than complexity or predictability of activity. We identified cases presenting in one of three acute phases of bipolar disorder and examined whether the application of non-linear dynamic models to the description of objectively measured activity can be used to predict case classification...

BACKGROUND: Little is known about how adoption factors into pregnancy decision making, particularly when abortion is unavailable. METHODS: We used data from the Turnaway Study, a longitudinal study of 956 women seeking abortion, including 231 women denied abortions owing to gestational limits. Through semiannual quantitative interviews, we assessed the frequency with which women denied abortion considered and choose adoption, and, among adoption participants, decision satisfaction...

Zhaleh Hosseini, Sayed-Amir Marashi
Flux coupling analysis is a computational method which is able to explain co-expression of metabolic genes by analyzing the topological structure of a metabolic network. It has been suggested that if genes in two seemingly fully-coupled reactions are not highly co-expressed, then these two reactions are not fully coupled in reality, and hence, there is a gap or missing reaction in the network. Here, we present GAUGE as a novel approach for gap filling of metabolic networks, which is a two-step algorithm based on a mixed integer linear programming formulation...

In immersive Virtual Reality systems, users tend to move in a Virtual Environment as they would in an analogous physical environment. In this work, we investigated how user behaviour is affected when the Virtual Environment differs from the physical space. We created two sets of four environments each, plus a virtual replica of the physical environment as a baseline. The first focused on aesthetic discrepancies, such as a water surface in place of solid ground. The second focused on mixing immaterial objects together with those paired to tangible objects...

Taehyun Rhee, Lohit Petikam, Benjamin Allen, Andrew Chalmers
This paper presents a novel immersive system called MR360 that provides interactive mixed reality (MR) experiences using a conventional low dynamic range (LDR) 360 (°) panoramic video (360-video) shown in head mounted displays (HMDs). MR360 seamlessly composites 3D virtual objects into a live 360-video using the input panoramic video as the lighting source to illuminate the virtual objects. Image based lighting (IBL) is perceptually optimized to provide fast and believable results using the LDR 360-video as the lighting source...

Modularity, modifiability, reusability, and API usability are important software qualities that determine the maintainability of software architectures. Virtual, Augmented, and Mixed Reality (VR, AR, MR) systems, modern computer games, as well as interactive human-robot systems often include various dedicated input-, output-, and processing subsystems. These subsystems collectively maintain a real-time simulation of a coherent application state. The resulting interdependencies between individual state representations, mutual state access, overall synchronization, and flow of control implies a conceptual close coupling whereas software quality asks for a decoupling to develop maintainable solutions...

BACKGROUND: Private-sector retail drug outlets are often the first point of contact for common health ailments, including tuberculosis (TB). Systematic reviews on public-private mix (PPM) interventions for TB did not perform in-depth reviews specifically on engaging retail drug outlets and related stakeholders in the pharmaceutical sector. Our objective was to better understand the extent to which the World Health Organization's (WHO) recommendation on engaging retail drug outlets has been translated into programmatic policy, strategy, and intervention in low- and middle-income countries...

BACKGROUND: Orthopaedic procedures, such as total hip replacement and total knee replacement, are among the commonest surgical procedures in England. The Getting it Right First Time project (GIRFT) aims to deliver improvements in quality and reductions in the cost of NHS orthopaedic care across the country. We will examine whether the planned changes have delivered improvements in the quality of care and patient outcomes. We will also study the processes involved in developing and implementing changes to care, and professional and organisational factors influencing these processes...

STUDY OBJECTIVE: Resident productivity, defined as new patients per hour, carries important implications for emergency department operations. In high-volume academic centers, essential staffing decisions can be made on the assumption that residents see patients at a static rate. However, it is unclear whether this model mirrors reality; previous studies have not rigorously examined whether productivity changes over time. We examine residents' productivity across shifts to determine whether it remained consistent...

STUDY QUESTION: Is periconceptional maternal one-carbon (I-C) metabolism associated with embryonic morphological development in non-malformed ongoing pregnancies? SUMMARY ANSWER: Serum vitamin B12, red blood cell (RBC) folate and plasma total homocysteine (tHcy) are associated with embryonic development according to the Carnegie stages. WHAT IS KNOWN ALREADY: Derangements in maternal I-C metabolism affect reproductive and pregnancy outcomes, as well as future health of the offspring...

Event history studies are commonly conducted in many fields, and a great deal of literature has been established for the analysis of the two types of data commonly arising from these studies: recurrent event data and panel count data. The former arises if all study subjects are followed continuously, while the latter means that each study subject is observed only at discrete time points. In reality, a third type of data, a mixture of the two types of the data earlier, may occur and furthermore, as with the first two types of the data, there may exist a dependent terminal event, which may preclude the occurrences of recurrent events of interest...

CONTEXT: Interest is growing in the use of qualitative data for assessment. Written comments on residents' in-training evaluation reports (ITERs) can be reliably rank-ordered by faculty attendings, who are adept at interpreting these narratives. However, if residents do not interpret assessment comments in the same way, a valuable educational opportunity may be lost. OBJECTIVES: Our purpose was to explore residents' interpretations of written assessment comments using mixed methods...

This educational intervention takes place when the population of older people with dementia is increasing. Health and Social care professionals must work jointly in increasingly complex contexts. Negative attitudes towards older people are cited as a contributor to poor care delivery, including the use of dismissive and/or patronising language, failing to meet fundamental needs and afford choice. 'Sliding Doors to Personal Futures' is a joint, drama-based, educational initiative between NHS Education Scotland and the Scottish Social Services Council, delivered using interprofessional education (IPE) towards encouraging person-centred health and social care...
