Introduction: Older adults have one of the highest age-specific suicide rates in France, and the risk of suicide is higher for those living in nursing homes. The aim of our study was to assess the effectiveness of gatekeeper training for nursing home staff on the knowledge and stigmas towards suicidal crisis and the impact on suicidal behaviour rates.

Method: A total of 427 nursing or administrative staff from 110 nursing homes received gatekeeper training in the Hauts-de-France French region between September 2016 and June 2018. First, knowledge and stigmas on suicidal crisis were assessed through a pretest and posttest survey. Second, a retrospective survey was conducted to determine suicide behaviour rates before and after training in nursing homes. Then, changes between pre- and posttraining scores and suicide rates were evaluated with a paired samples T test and rate difference calculation (P value of <0.05 was considered statistically significant).

Results: A total of 315 trainees completed the questionnaires on knowledge and stigmas related to suicidal crisis, and we found a significant difference in the total scores (P < 0.01). Moreover, we found a significant decrease in the incidence of suicide attempts (SAs) after training (P = 0.002), but the incidence of deaths by suicide was not significantly different prior to and after the training course (P = 0.46).

Conclusion: We highlighted an improvement in knowledge and stigmas after training and a reduction in the rates of SAs with our gatekeeper suicide prevention program. Future research is needed to improve suicide prevention for nursing home residents.

Importance: Accurately diagnosing neurodegenerative dementia is often challenging due to overlapping clinical features. Disease specific biomarkers could enhance diagnostic accuracy. However, CSF analysis procedures and advanced imaging modalities are either invasive or high-priced, and routinely unavailable. Easily accessible disease biomarkers would be of utmost value for accurate differential diagnosis of dementia subtypes.

Objective: To assess the diagnostic accuracy of blood-based biomarkers for the differential diagnosis of AD from Frontotemporal Lobar Degeneration (FTLD), or AD from Dementia with Lewy Bodies (DLB).

Methods: Systematic review. Three databases (PubMed, Scopus, and Web of Science) were searched. Studies assessing blood-based biomarkers levels in AD versus FTLD, or AD versus DLB, and its diagnostic accuracy, were selected. When the same biomarker was assessed in three or more studies, a meta-analysis was performed. QUADAS-2 criteria were used for quality assessment.

Results: Twenty studies were included in this analysis. Collectively, 905 AD patients were compared to 1262 FTLD patients, and 209 AD patients were compared to 246 DLB patients. Regarding biomarkers for AD versus FTLD, excellent discriminative accuracy (AUC >0.9) was found for p-tau181, p-tau217, synaptophysin, synaptopodin, GAP43 and calmodulin. Other biomarkers also demonstrated good accuracy (AUC = 0.8-0.9). For AD versus DLB distinction, only miR-21-5p and miR-451a achieved excellent accuracy (AUC >0.9).

Conclusion: Encouraging results were found for several biomarkers, alone or in combination. Prospective longitudinal designs and consensual protocols, comprising larger cohorts and homogeneous testing modalities across centres, are essential to validate the clinical value of blood biomarkers for the precise etiological diagnosis of dementia.

Informal caregivers can experience various demands when providing care and support for People with Parkinson's disease (PwP) in their own homes. The outbreak of SARS-CoV-2 and public health strategies employed to mitigate the spread of COVID-19 have presented challenges to the general populace on a global basis. The present study used a qualitative research design to explore how the COVID-19 pandemic has impacted informal caregivers in their role of providing care for PwP in their own homes. A series of 1:1 semi-structured interviews were conducted with 11 informal caregivers of PwP (M age = 72.64 years, SD = 8.94 years). A thematic analysis indicated that 1) vulnerabilities to COVID-19, 2) home maintenance & activities of daily living and 3) engagement with healthcare services were 3 themes that provided indications on how the COVID-19 pandemic impacted informal caregivers of PwP. The present study provides illustrations of how being an informal caregiver of PwP and being identified as high risk to COVID-19 can present challenges to the process of caring for loved ones who are also vulnerable to SARS-CoV-2. The results of the present study highlights the necessity to develop strategies to ensure that informal caregivers have the necessary resources to provide care for PwP in their homes and also maintain their own well-being in the post COVID-19 era.

Objective and research design This study investigated whether the relationship between experiential avoidance and carer depression is mediated by cognitive fusion using path analysis and whether this model differs between family carers from Japan, Spain, and the UK using multi-group path analysis. Results The whole sample model (N = 745) showed a good fit to the data. The direct effect of experiential avoidance on carer depression (β = .10) and its indirect effect on carer depression through cognitive fusion (β = .15) were significant. Examined variables accounted for 45% of the variance of depression. Multi-group path analysis confirmed the same pattern of indirect path across 3 countries, while the direct path was no longer significant in Spanish and UK samples.Conclusion These findings suggest that targeting cognitive fusion may be particularly critical in culturally diverse carers and pre-emptive efforts to reduce experiential avoidance using psychological techniques may be beneficial among family carers prone to cognitive fusion regardless of cultural differences.

Introduction: This study aims to measure frequency and correlates of initial idiopathic psychiatric diagnosis in a cohort of 147 patients with Frontotemporal Dementia (FTD)-spectrum disorders.

Methods: Participants were evaluated at the National Institutes of Health in Bethesda, Maryland. Initial participant diagnoses were determined by chart review and patient and informant interviews. Logistic regression was used to assess the relationships between diagnosis and age of symptom onset, gender, education, family history of psychiatric illness, and family history of dementia. Additional exploratory analyses investigated patients' first symptom type.

Results: 25% (n=43) of all the patients reviewed were initially misdiagnosed with an idiopathic psychiatric illness, which is less than half the commonly cited 50% rate.³ Depression was the most common misdiagnosis (46.5%). Family history of dementia, family history of mental illness and an exploratory analysis of behavioral first symptoms suggested significant association with a greater likelihood of initial idiopathic psychiatric diagnosis in FTD patients.

Discussion: This data confirms patterns of initial idiopathic psychiatric diagnosis in FTD and elucidates potential factors underlying misdiagnosis. Potential implications for patient outcomes, caregiver burden and healthcare costs are discussed.

Background: To our knowledge, no systematic reviews and meta-analyses have yet been published that examine the effect of art therapy (AT) interventions on depression symptoms among older adults, and this study aimed to systematically review and meta-analysis of clinical trials, summarize eligible relevant studies and provide a true effect measure for the association between AT and depression symptoms in older adults.

Methods: The databases of PubMed, Web of Science, Scopus, and the Cochrane Central Register of Controlled Trials were searched until 15 February 2022. The methodological quality of the included studies was evaluated by the Delphi checklist. The heterogeneity across studies was conducted by chi-squared test and measured its quantity by the I² statistic. We performed this meta-analysis to obtain a summary measure of the mean difference in depression scores between AT and control groups using a random-effects model. All statistical analyses were carried out at a significance level of .05 using Stata software, version 14.

Results: Until 15 February 2022, 222 studies through databases and 199 studies through review of references were included in the present meta-analysis. In total, the analysis covered 8 studies. The difference in mean depression score between the intervention and control groups showed significant reductions in the AT group (MD -.78; 95% CI: -1.17, -.38; I 2 = 67.9%).

Conclusion: Our findings suggest that AT can be considered an effective intervention for reducing depression symptoms among older adults and art therapists/psychotherapists can use this method to reduce the symptoms of depression among older adults.
