Circadian disturbances, anxiety and motor disturbances differentiate delirium superimposed on dementia from dementia-only.

Background: To ensure adequate treatment, individuals with delirium superimposed on dementia (DSD) need to be differentiated reliably from those with dementia only (DO). Therefore, we aimed to examine the clinical indicators of DSD by assessing motor subtypes, cognitive performance and neuropsychiatric symptoms in DSD and DO patients. Methods: Cross-sectional design with the Delirium-Motor-Subtyping Scale (DMSS), Mini-Mental-State-Examination (MMSE), Clock-Drawing-Test (CDT), DemTect, and Neuropsychiatric Inventory assessed after admission to an acute hospital. Results: 94 patients were included, 43 with DSD (78 ± 7 years, MMSE = 11 ± 9) and 51 with DO (79 ± 7 years, MMSE = 9 ± 8). DMSS "no subtype" was more common in the DO group (26% vs. 10%, p = .04). The DSD group showed lower CDT scores (DSD: M = 4 ± 3 vs. DO: M = 6 ± 1; p < .001) and higher anxiety (DSD: MED = 3 ± 8 vs. DO: MED = 3 ± 4; p = .01) and sleep/night-time behavior disturbances (DSD: MED = 0 ± 6 vs. DO: MED = 0 ± 0; p = .02). Conclusions: Sleep/night-time behavior disturbances appear to be a clinical indicator of DSD. Motor subtypes can identify cases at increased risk of developing delirium or unrecognized delirium.

Clinical teaching in applied health science: effects of a student-led journal club on aging and physical activity.

BACKGROUND: This project aims to investigate the effects of a student-led journal club on students' critical thinking and clinical application skills in the academic field of aging and physical activity. METHODS: A pre-post design analysis with data collected in four successive cohorts of the program M.Sc. Sport and Movement Gerontology was conducted. Each student assigned himself/herself to a study, and then led the journal club discussion and published a summary of the journal club via graphical abstract on social media. The students rated their perceived confidence in the beginning (T0) and after the semester (T1) via questionnaire and 5-point Likert scales addressing their ability to review and summarize the evidence, to present it in a journal club and to lead the discussion. RESULTS: 41 students (32 women, M = 25 years SD 1.9 years) were included. The journal club was rated as "very good" (median 2, IQR 1). Students' confidence on participating, leading the journal club and transferring the results into clinical practice improved significantly (r ≥ 0.6, p < 0.01) - e.g.: "I feel confident in leading a discussion on the literature presented", T0: "undecided" (median 3, IQR 2) to T1: "rather agree" (median 4, IQR 1, Z= -5.41, r = 0.85, p < 0.01). DISCUSSION: The student-led journal club shows to be an effective teaching approach for the field of aging and physical activity within applied health science education. Especially the students' self-assignment to the studies and involving the scientific community via social media was rated as useful and highly motivating for students and lecturers.

Short-term aerobic exercise for depression in acute geriatric psychiatry: study protocol for a randomized controlled trial.

BACKGROUND: Major depression is one of the main mental illnesses in old age, with acute exacerbated episodes requiring treatment in geriatric psychiatry. A meta-analysis showed that aerobic exercise in moderate intensity has large effects in older adults with major depression, but there is no evidence of aerobic exercise in geriatric psychiatry. Therefore, this study aims to analyze the feasibility and effects of an ergometer-based aerobic exercise on depressive symptoms. METHODS: A single-center randomized controlled trial will be conducted in an acute geriatric psychiatric hospital. Inpatients allocated to the intervention group will receive a 2-week aerobic ergometer program. The control group will receive seated flexibility exercise in addition to usual care. The overall effects on the patients' depressive symptoms will be measured by clinical global impression of change (CGI) as the primary outcome. Changes in depressive symptom domains, physical (in)activity, and aerobic performance as well as the dosage of applied antidepressants will be examined as secondary outcomes. DISCUSSION: This short-term aerobic exercise program is expected to decrease depressive symptoms in acute exacerbated periods in older adults. The results may increase the evidence for implementing physical activity interventions in acute hospital settings. The disease-related motivation for exercise in acute exacerbated depressive periods will be the most challenging aspect. The treatment of depression requires new cost-effective approaches, especially in acute geriatric psychiatry with potential benefits for patients, family members, and clinicians. TRIAL REGISTRATION: German Clinical Trial Register ID: DRKS00026117 TRIAL STATUS: Protocol Version 1.2 dated February 23, 2022. By February 23, 2022, the trial had recruited a total of 15 participants in two wards at the Department of Geriatric Psychiatry at the LVR-Hospital Cologne. Recruitment started on November 12, 2021. The recruitment is expected to continue for at least 12 months.

Post-discharge Mortality in Patients With Delirium and Dementia: A 3-Year Follow Up Study.

Background: Delirium and dementia are prominent psychiatric diseases in old age and connected with poor outcomes for people affected. Nevertheless, there is a lack of knowledge concerning the long-term prognosis of patients with dementia and delirium. This study analyzes mortality, readmission rates and discharge destinations of patients with dementia or delirium superimposed on dementia (DSD) within 3 years after discharge from hospital. Methods: A cross-sectional, monocentric cohort study was conducted at the department of geriatric psychiatry of the LVR hospital cologne, using structured telephone interviews and analyses from the clinical information system. All patients with dementia and DSD, admitted between December 2014 and November 2015, were screened for eligibility. Results: In total, 113 patients were included, 49 patients with dementia (M 80 years, female 49%) and 64 with DSD (M 82 years, female 47%). Three years after discharge, 66 patients (58%) had died (95% CI 91.9-112.5; p = 0.53). Within the first 3 months, 9 patients (14%) with DSD deceased, but no patient from the dementia group (95% CI 11.3-12.7; p = 0.01). Out of all patients, 17 patients were readmitted and nursing homes were the predominant discharge destination (55%). Conclusions: This analysis revealed a high post-discharge mortality rate of patients with dementia and DSD. For patients with DSD, a close clinical monitoring, mainly within the first 3 months after discharge, should challenge the significantly increased acute-mortality. These findings should set the pattern for a comprehensive analysis of long-term effects of dementia and DSD. More studies are required for better understanding and comparability in this field of research and healthcare.

Effects of Mind-Body Interventions Involving Meditative Movements on Quality of Life, Depressive Symptoms, Fear of Falling and Sleep Quality in Older Adults: A Systematic Review with Meta-Analysis.

Background: The aim of the present systematic meta-analytical review was to quantify the effects of different mind-body interventions (MBI) involving meditative movements on relevant psychological health outcomes (i.e., quality of life (QoL), depressive symptoms, fear of falling (FoF) and sleep quality) in older adults without mental disorders. Methods: A structured literature search was conducted in five databases (Ovid, PsycINFO, PubMed, SPORTDiscus, Web of Science). Inclusion criteria were: (i) the study was a (cluster) randomized controlled trial, (ii) the subjects were aged ≥59 years without mental illnesses, (iii) an intervention arm performing MBI compared to a non-exercise control group (e.g., wait-list or usual care), (iv) psychological health outcomes related to QoL, depressive symptoms, FoF or sleep quality were assessed and (v) a PEDro score of ≥5. The interventions of the included studies were sub-grouped into Tai Chi/Qigong (TCQ) and Yoga/Pilates (YP). Statistical analyses were conducted using a random-effects inverse-variance model. Results: Thirty-seven randomized controlled trials (RCTs) (comprising 3224 participants) were included. Small to moderate-but-significant overall effect sizes favoring experimental groups (Hedges' g: 0.25 to 0.71) compared to non-exercise control groups were observed in all outcomes (all p values ≤ 0.007), apart from one subdomain of quality of life (i.e., social functioning, p = 0.15). Interestingly, a significant larger effect on QoL and depressive symptoms with increasing training frequency was found for TCQ (p = 0.03; p = 0.004). Conclusions: MBI involving meditative movements may serve as a promising opportunity to improve psychological health domains such as QoL, depressive symptoms, FoF and sleep quality in older adults. Hence, these forms of exercise may represent potential preventive measures regarding the increase of late-life mental disorders, which need to be further confirmed by future research.
