Trait anxiety mediates the effect of stress exposure on post-traumatic stress disorder and depression risk in cardiac surgery patients
BACKGROUND: Post-traumatic stress disorder (PTSD) and depression are common after cardiac surgery. Lifetime stress exposure and personality traits may influence the development of these psychiatric conditions. METHODS: Self-reported rates of PTSD and depression and potential determinants (i.e., trait anxiety and stress exposure) were established 1.5 to 4 years after cardiac surgery. Data was available for 1125 out of 1244 (90.4%) participants. Multivariable linear regressions were conducted to investigate mediating and/or moderating effects of trait anxiety on the relationship between stress exposure, and PTSD and depression. Pre-planned subgroup analyses were performed for both sexes. RESULTS: PTSD and depression symptoms were present in 10.2% and 13.1% of the participants, respectively. Trait anxiety was a full mediator of the association between stress exposure and depression in both the total cohort and female and male subgroups. Moreover, trait anxiety partially mediated the relationship between stress exposure and PTSD in the full cohort and the male subgroup, whereas trait anxiety fully mediated this relationship in female patients. Trait anxiety did not play a moderating role in the total patient sample, nor after stratification on gender. LIMITATIONS: The unequal distribution of male (78%) and female patients (22%) might limit the generalizability of our findings. Furthermore, risk factors were investigated retrospectively and with variable follow-up time. CONCLUSIONS: In cardiac surgery patients, trait anxiety was found to be an important mediator of postoperative PTSD and depression. Prospective research is necessary to verify whether these factors are reliable screening measures of individuals' vulnerability for psychopathology development after cardiac surgery
User-Centred Approach to Design an Online Social Support Platform for Seniors : Identification of Users' Types and Their Requirements
A well-designed social platform has the potential to reduce senior isolation and promote active ageing. However, to design tools that respond to the user need it is important to understand what types of seniors will use it and what are their needs. Through a user-oriented approach at several design stage: focus group, co-creation and usability test we were able to identify the different roles related to the use of the platform, which allowed us to classify them by type, each type having very specific needs. Among the types of users identified, "Active users" are looking for an efficient platform. "Socialiser users" are more passive and mainly interested to participate in activities and are sensitive to trust. "Low skilled users" have limited digital skills and must be accompanied to start with the platform. Finally, "Sporadic users" lack of time to actively use the platform but would use a platform involving a large number of stakeholders. It is important to include all these different types of users in the design phase to ensure the future success of the social platform
Designing an online social support platform through co-creation with seniors
The high number of seniors that feels excluded of society highlights the necessity to promote active ageing. This intention can be supported through online platforms that encourage participation in social activities. The goal of the present study was to identify design principles of online support platforms for seniors through focus groups and to ideate the platform through co-creation sessions. The results show that a social platform for seniors must, among other, help to foster contact between users, and must provide services and meaningful activities. A first mock-up of the platform's design has been created based on the co-creation sessions and will be iteratively evaluated and enhanced in future studies in four countries across Europe. Our findings are in line with those of other studies demonstrating that seniors attach importance to trustworthiness and need to maintain social ties
Active involvement of people with dementia: a systematic review of studies developing supportive technologies
Although there are promising benefits of supportive technology in dementia care, use of these technologies is still limited. It is challenging for researchers and developers in this field to actively involve people with dementia in development. This review updates and builds on existing knowledge by including a contemporary and relevant perspective. This perspective was gained by including search words and search databases from the field of Human Computer Interaction (HCI) and Design, as these fields were expected to supply novel insights in the complex task of actively involving people with dementia in developing supportive technologies. A total of 49 out of 3456 studies were included which describe the development of a great variety of technologies. Often people with dementia were involved in the generative or evaluative phase of the development. Interviews and observations were most commonly used methods. In seven articles the people with dementia were co-designers. This literature review reflects that people with dementia can influence the development of technology in regards to content, design, and even the initial idea, although the impact on how they experience their own involvement remains largely unknown. There is a lack of specific knowledge on appropriate methods and materials for active involvement of people with dementia in supportive technology development, even when including articles from the field of HCI and Design. Future research is needed to further appreciate and improve the desired role of people with dementia in meaningful technology development
A lifestyle monitoring system to support (in)formal caregivers of people with dementia: Analysis of users need, benefits, and concerns
Introduction Dementia is a syndrome that predominantly affects people in old age. Many older people with mild to moderate dementia live at home alone. When dementia poses problems, they must rely on informal caregivers, who have lives of their own in other places, as well as on professional home care organized by case managers. Assistive technologies, such as lifestyle monitoring, are being developed to assist informal caregivers and case managers by making remote caregiving possible. In a study conducted in the northern Netherlands, people with dementia were provided with a lifestyle monitoring system consisting of activity sensors in the home connected to an online platform. This study is intended to generate insight into needs, benefits, and concerns relating to a lifestyle-monitoring system to help informal caregivers and case managers provide care to people with dementia who are living alone. The key research questions are as follows: Which needs, benefits, and concerns are reported by informal caregivers and case managers who use lifestyle monitoring? What does the collected information indicate about the adoption of lifestyle monitoring? Methodology In the study, 63 lifestyle-monitoring systems were installed in 63 homes of people with mild to moderate dementia who were living alone. We guaranteed that the system could be used without charge until the end of the trial. We conducted telephone interviews with informal caregivers (50) near the date on which the system was installed, and again when it had been in use for approximately 300 days (41). We also interviewed case managers (13) at the beginning and at the end of the project (7). Each interview lasted about 30 minutes and consisted of closed and open questions about topics including expectations, experiences, quality of life, and care. The study took place in the rural area of the northern Netherlands from February 2015 to June 2016. Four homecare organizations provided lists of participants to include in the study. Results/conclusion The results indicate that informal caregivers perceive lifestyle monitoring as a support tool that fills a need in the provision of care for people with dementia and that its benefits outweigh the concerns. Lifestyle monitoring makes it possible to expand the informal care network such that care duties can be shared among more people, thereby relieving informal caregivers of a sense of constant responsibility

The Effect of Dexamethasone on Symptoms of Posttraumatic Stress Disorder and Depression After Cardiac Surgery and Intensive Care Admission: Longitudinal Follow-Up of a Randomized Controlled Trial
Objective: Cardiac surgery and postoperative admission to the ICU may lead to posttraumatic stress disorder and depression. Perioperatively administered corticosteroids potentially alter the risk of development of these psychiatric conditions, by affecting the hypothalamic-pituitary-adrenal axis. However, findings of previous studies are inconsistent. We aimed to assess the effect of a single dose of dexamethasone compared with placebo on symptoms of posttraumatic stress disorder and depression and health-related quality of life after cardiac surgery and ICU admission. Design: Follow-up study of a randomized clinical trial. Setting: Five Dutch heart centers. Patients: Cardiac surgery patients (n = 1,244) who participated in the Dexamethasone for Cardiac Surgery trial. Interventions: A single intraoperative IV dose of dexamethasone or placebo was administered in a randomized, double-blind way. Measurements and Main Results: Symptoms of posttraumatic stress disorder, depression, and health-related quality of life were assessed with validated questionnaires 1.5 years after randomization. Data were available for 1,125 patients (90.4%); of which 561 patients received dexamethasone and 564 patients received placebo. Overall, the prevalence of psychopathology was not influenced by dexamethasone. Posttraumatic stress disorder and depression were present in, respectively, 52 patients (9.3%) and 69 patients (12.3%) who received dexamethasone and in 66 patients (11.7%) and 78 patients (13.8%) who received placebo (posttraumatic stress disorder: odds ratio, 0.82; 95% CI, 0.55-1.20; p = 0.30; depression: odds ratio, 0.92; 95% CI, 0.64-1.31; p = 0.63). Subgroup analysis revealed a lower prevalence of posttraumatic stress disorder (odds ratio, 0.23; 95% CI, 0.07-0.72; p <0.01) and depression (odds ratio, 0.29; 95% CI, 0.11-0.77; p <0.01) in female patients after dexamethasone administration. Health-related quality of life did not differ between groups and was not associated with psychopathology. Conclusions: Overall, our findings suggest that exogenous administration of the glucocorticoid receptor agonist dexamethasone-compared with placebo-during cardiac surgery does not positively or negatively affect the prevalence of posttraumatic stress disorder and depression. However, in female patients, beneficial effects on the occurrence of posttraumatic stress disorder and depression may be present
