In the context of industrial production, a worker that wants to program a robot using the hand-guidance technique needs that the robot is available to be programmed and not in operation. This means that production with that robot is stopped during that time. A way around this constraint is to perform the same manual guidance steps on a holographic representation of the digital twin of the robot, using augmented reality technologies. However, this presents the limitation of a lack of tangibility of the visual holograms that the user tries to grab. We present an interface in which some of the tangibility is provided through ultrasound-based mid-air haptics actuation. We report a user study that evaluates the impact that the presence of such haptic feedback may have on a pick-and-place task of the wrist of a holographic robot arm which we found to be beneficial.

Despite the convenience offered by e-commerce, online apparel shopping presents various product-related risks, as consumers can neither physically see nor try products on themselves. Augmented reality (AR) and virtual reality (VR) technologies have been used to improve the shopping online experience. Therefore, we propose an AR- and VR-based try-on system that provides users a novel shopping experience where they can view garments fitted onto their personalized virtual body. Recorded personalized motions are used to allow users to dynamically interact with their dressed virtual body in AR. We conducted two user studies to compare the different roles of VR- and AR-based try-ons and validate the impact of personalized motions on the virtual try-on experience. In the first user study, the mobile application with the AR- and VR-based try-on is compared to a traditional e-commerce interface. In the second user study, personalized avatars with pre-defined motion and personalized motion is compared to a personalized no-motion avatar with AR-based try-on. The result shows that AR- and VR-based try-ons can positively influence the shopping experience, compared with the traditional e-commerce interface. Overall, AR-based try-on provides a better and more realistic garment visualization than VR-based try-on. In addition, we found that personalized motions do not directly affect the user’s shopping experience.

Objectives.This study aimed to establish the prevalence of multimorbidity in women diagnosed with osteoporosis and to report it by deprivation index. The characteristics of comorbidity in osteoporotic women are compared to the general female chronic population, and the impact on healthcare expenditure of this population group is estimated.Methods.A cross-sectional analysis that included all Basque Country women aged 45 years and over (N= 579,575) was performed. Sociodemographic, diagnostic, and healthcare cost data were extracted from electronic databases for a one-year period. Chronic conditions were identified from their diagnoses and prescriptions. The existence of two or more chronic diseases out of a list of 47 was defined as multimorbidity.Results.9.12% of women presented osteoporosis and 85.04% of them were multimorbid. Although multimorbidity in osteoporosis increased with age and deprivation level, prevalence was higher in the better-off groups. Women with osteoporosis had greater risk of having other musculoskeletal disorders but less risk of having diabetes (RR = 0.65) than chronic patients without osteoporosis. People with poorer socioeconomic status had higher healthcare cost.Conclusions.Most women with osteoporosis have multimorbidity. The variety of conditions emphasises the complexity of clinical management in this group and the importance of maintaining a generalist and multidisciplinary approach to their clinical care.

Abstract The increasing prevalence of chronic disease generates significant financial, social and psychosocial burden for patients, families and healthcare system. Interprofessional collaboration (IPC) is becoming recognized as a discipline among health and social care professionals and medical training institutions worldwide. Literature research suggests that following interventions could be particularly useful in the management of chronic patients. The objective of this systematic review was to assess the impact of IPC on chronic patients compared to standard health-care practice. The PICO model was adopted and three electronic databases (Medline, EMBASE, Web of Science) were searched using appropriate keywords. Selected trials were assessed for quality and risk of bias using the National Institutes of Health Quality Assessment of Controlled Intervention Studies. Data were analyzed using descriptive statistic, and comparison of outcomes among teams with or without pharmacist was performed using t-Student test (p < 0,05). Out of 11.128, 24 studies met the inclusion criteria and 58 indicators were identified: 62% improved significantly, 38% did not show any variation, no indicator worsened after intervention. In particular, systolic blood pressure (SBP) showed a statistically significant improvement in 70.0 % of trials in which was considered while did not show any difference in the rest. The presence of a pharmacist in the team show a statistically significant improvement on SBP (p = 0,002) in patients with hypertension while no statistically significant effect is observed on glycated hemoglobin (p = 0,193) in diabetics. The results support that IPC contributes to positive patient, provider and institutional level outcomes, in particular for chronic conditions. Future research should focus on the inclusion of patient/caregivers in the collaborative team, and on the role of interprofessional education (IPE) on collaborative practice in the management of the patient with chronicity. Key messages IPC is an innovative strategy to address the complex health needs of chronic populations. Further studies are needed to evaluate the role of IPE in achieving better IPC and improving chronic patients’ outcomes.

We present a user study to investigate the impact of explanations on non-experts? understanding of reinforcement learning (RL) agents. We investigate both a common RL visualization, saliency maps (the focus of attention), and a more recent explanation type, reward-decomposition bars (predictions of future types of rewards). We designed a 124 participant, four-treatment experiment to compare participants? mental models of an RL agent in a simple Real-Time Strategy (RTS) game. Our results show that the combination of both saliency and reward bars were needed to achieve a statistically significant improvement in mental model score over the control. In addition, our qualitative analysis of the data reveals a number of effects for further study.

What happens to schizophrenics after their discharge to the community has been a subject of several recent studies. Most of this work is from the Social Psychiatry Research Unit at the Maudsley Hospital and deals with prospects of rehabilitation and resettlement, morbidity in the community, and the impact which these patients have on their families. Earlier follow-up studies of chronic patients who left certain London hospitals between 1949 and 1956 point to a satisfactory resettlement in two-thirds of cases (Brown et al., 1958). In more recent papers rather cautious conclusions were drawn, especially where morbidity in the community and not just lengths of hospital stay and re-admission rates were ascertained (Wing, 1963; Wing et al., 1964). Whilst the time spent in hospital by schizophrenics is now much shorter, re-admission rates continue to rise, and according to Wing “… in the absence of effective community services the policy of early discharges is based to a large degree on the willingness of relatives to attempt the role of nurse and put up with considerable discomfort and distress”. Furthermore, with existing services so different in various parts of the country, no reliable data exist which would indicate to what extent a fully developed community service could prevent morbidity of discharged schizophrenics. What is needed, according to Wing, would be a combination of the Nottingham community services, the Worthing day-centre and industrial workshops on the Bristol pattern.
