Association between sedentary time and cognitive function: A focus on different domains of sedentary behavior.

Studies which examined the association between sedentary behavior (SB) and cognitive function have presented equivocal findings. Mentally active/inactive sedentary domains may relate differently to cognitive function. We examined associations between SB and cognitive function, specifically focusing on different domains. Participants were recruited from the Nijmegen Exercise Study 2018 in the Netherlands. SB (hours/day) was measured with the Sedentary Behavior Questionnaire. Cognitive function was assessed with a validated computer self-test (COST-A), and a z-score calculated for global cognitive function. Multivariate linear regression assessed associations between tertiles of sedentary time and cognitive function. Cognition tests were available from 2821 participants, complete data from 2237 participants (43% female), with a median age of 61 [IQR 52-67] and a mean sedentary time of 8.3 ± 3.2 h/day. In fully adjusted models, cognitive function was significantly better in participants with the highest total sedentary time (0.07 [95% CI 0.02-0.12], P = 0.01), work-related sedentary time (0.13 [95% CI 0.07-0.19], P  0.05). We found a strong, independent positive association between total SB and cognitive function in a heterogenous population. This relation was not consistent across different domains, with especially work- and computer-related SB being positively associated with cognitive function. This highlights the importance of assessing the various sedentary domains in understanding the relation between sedentary time and cognitive function

The Cognitive Online Self-Test Amsterdam (COST-A): Establishing norm scores in a community-dwelling population.

Background: Heightened public awareness about Alzheimer's disease and dementia increases the need for at-home cognitive self-testing. We offered Cognitive Online Self-Test Amsterdam (COST-A) to independent groups of cognitively normal adults and investigated the robustness of a norm-score formula and cutoff. Methods: Three thousand eighty-eight participants (mean age ± standard deviation = 61 ± 12 years, 70% female) completed COST-A and evaluated it. Demographically adjusted norm scores were the difference between expected COST-A scores, based on age, gender, and education, and actual scores. We applied the resulting norm-score formula to two independent cohorts. Results: Participants evaluated COST-A to be of adequate difficulty and duration. Our norm-score formula was shown to be robust: ≈8% of participants in two cognitively normal cohorts had abnormal scores. A cutoff of -1.5 standard deviations proved optimal for distinguishing normal from impaired cognition. Conclusion: With robust norm scores, COST-A is a promising new tool for research and clinical practice, providing low cost and minimally invasive remote assessment of cognitive functioning

Understanding patients' satisfaction with physician assistant/associate encounters through communication experiences: a qualitative study in acute hospitals in England.

BACKGROUND: Physician assistants/associates (PAs) are a recent innovation in acute hospital teams in England and many other countries worldwide. Although existing evidence indicates generally high levels of patient satisfaction with their PA hospital encounters, little is known about the factors associated with this outcome. There is a lack of evidence on the process of PA-patient communication in hospital encounters and how this might influence satisfaction. This study therefore aimed to understand patients' satisfaction with PA acute hospital encounters through PA-patient communication experiences. METHODS: A qualitative study was conducted among patients and representatives of patients seen by or receiving care from one of the PAs working in acute hospital services in England. Semi-structured interviews were undertaken face-to-face with study participants in the hospital setting and shortly after their PA encounter. Data were coded and analysed using thematic analysis. The study was framed within a theoretical model of core functions of medical encounter communication. RESULTS: Fifteen patients and patient representatives who had experienced a PA encounter participated in interviews, across five hospitals in England. Four interrelated communication experiences were important to participants who were satisfied with the encounter in general: feeling trust and confidence in the relationship, sharing relevant and meaningful information, experiencing emotional care and support, and sharing discussion on illness management and treatment. However, many participants misconceived PAs to be doctors, raising a potential risk of reduced trust in the PA relationship and negative implications for satisfaction with their PA encounter. Participants considered it beneficial that patients be informed about the PA role to prevent confusion. CONCLUSIONS: PA encounters offer a constructive example of successful clinician-patient communication experiences in acute hospital encounters from the patient's perspective. Study participants were generally naïve to the PA role. Hospital services and organisations introducing these mid-level or advanced care practitioner roles should consider giving attention to informing patients about the roles

The latter is commonly referred to as young-onset dementia (YOD). The diagnosis not only has an impact on the persons with YOD but also on their family members. For family members, the diagnosis changes their lives, as responsibilities and roles alter when the care and wellbeing of the relative increasingly come into focus. The aim of this study was to explore family members’ experiences of sharing lives with a relative diagnosed with YOD – from onset of symptoms until the person relocated to a nursing home.Patients and Methods: The study has a qualitative approach with in-depth interviews. In total, the study included 15 family members aged ≥ 18 years participated, all with a relative diagnosed with dementia before the age of 65. At the time of the interview, all had a relative living in a nursing home. The interviews were analyzed using thematic analysis.Results: Two key themes were identified: Becoming responsible and Dealing with the situation. Family members found themselves increasingly responsible for many parts of their relatives’ lives and forced to make decisions on their behalf. This was experienced as being lonely, as family members wished to share their responsibility. Despite of their efforts to control and deal with their situation, family members reported a lack of power to influence certain factors, such as access to appropriate healthcare services, causing feelings of distress.Conclusion: These findings emphasize the need of improved and tailored support and guidance for family members of persons with YOD. Further, the findings highlight the importance of increased knowledge and awareness among social workers and other healthcare professionals regarding support to family members of persons with YOD.Keywords: YOD, relative, psychosocial support, qualitative, health care syste
