Interventions in ambulatory healthcare settings to reduce social isolation among adults aged 18-64: a systematic review.

BACKGROUND: Social isolation is associated with increased all-cause and premature mortality, poor chronic disease management, and mental health concerns. Limited research exists on interventions addressing social isolation among individuals under 65 despite its increasing prevalence among young and middle-aged adults. AIM: To identify interventions from the extant literature that address social isolation and loneliness in ambulatory healthcare settings in adults aged 18-64, and to identify elements of successful studies for future intervention design. DESIGN & SETTING: Systematic review of interventions targeting social isolation in community-dwelling adults aged 18-64 within ambulatory healthcare settings. METHOD: A search strategy was developed to identify relevant articles in the following databases: Ovid MEDLINE, Embase, EBM Reviews, Scopus, CINAHL and PsychInfo. Data were extracted on study design and setting, intervention type, outcome related to social isolation/loneliness and scale of measure used. RESULTS: 25,078 citations were identified and underwent title and abstract screening. 75 articles met our inclusion criteria and were synthesised, including an assessment of bias. Effective interventions were delivered in community health settings, incorporated a group component, and used digital technologies. They also addressed the association between mental health and social isolation using CBT approaches and enhanced self-management and coping strategies for chronic conditions through psycho-educational interventions. CONCLUSION: Future research should prioritise adults living in low- and middle-income countries, racialized individuals, as well as those with fewer educational opportunities. There is also a need to advance research in primary care settings, where longitudinal patient-provider relationships would facilitate the success of interventions.

Structural Violence Education: A Critical Moment for Psychiatric Training.

The mental health ramifications of structural violence are borne disproportionately by marginalized patient populations in North America, which includes Black, Indigenous, and 2SLGBTQIA+ communities and people who use drugs. Structural violence can comprise, for example, police or state violence, colonialism, and medical violence. We chronicle the history of psychiatric discourse around structural violence over the past 50 years and highlight the critical need for new formalized competencies to become incorporated into the training of medical students across Canada, specifically addressing the impacts of structural violence for the aforementioned populations. Finally, we offer a framework of learning objectives for designing educational sessions discussing structural violence and mental health for integration into pre-clerkship psychiatry curricula at medical schools across Canada.

Characterizing early Canadian federal, provincial, territorial and municipal nonpharmaceutical interventions in response to COVID-19: a descriptive analysis.

BACKGROUND: Nonpharmaceutical interventions (NPIs) are the primary tools to mitigate early spread of the coronavirus disease 2019 (COVID-19) pandemic; however, such policies are implemented variably at the federal, provincial or territorial, and municipal levels without centralized documentation. We describe the development of the comprehensive open Canadian Non-Pharmaceutical Intervention (CAN-NPI) data set, which identifies and classifies all NPIs implemented in regions across Canada in response to COVID-19, and provides an accompanying description of geographic and temporal heterogeneity. METHODS: We performed an environmental scan of government websites, news media and verified government social media accounts to identify NPIs implemented in Canada between Jan. 1 and Apr. 19, 2020. The CAN-NPI data set contains information about each intervention's timing, location, type, target population and alignment with a response stringency measure. We conducted descriptive analyses to characterize the temporal and geographic variation in early NPI implementation. RESULTS: We recorded 2517 NPIs grouped in 63 distinct categories during this period. The median date of NPI implementation in Canada was Mar. 24, 2020. Most jurisdictions heightened the stringency of their response following the World Health Organization's global pandemic declaration on Mar. 11, 2020. However, there was variation among provinces or territories in the timing and stringency of NPI implementation, with 8 out of 13 provinces or territories declaring a state of emergency by Mar. 18, and all by Mar. 22, 2020. INTERPRETATION: There was substantial geographic and temporal heterogeneity in NPI implementation across Canada, highlighting the importance of a subnational lens in evaluating the COVID-19 pandemic response. Our comprehensive open-access data set will enable researchers to conduct robust interjurisdictional analyses of NPI impact in curtailing COVID-19 transmission.

Nonsuicidal self-injury, suicidal ideation, and suicide attempt among collegiate athletes: Findings from the National College Health Assessment.

OBJECTIVE: To evaluate whether collegiate athletes and nonathlete college students differ in nonsuicidal self-injury (NSSI), suicidal ideation, suicide attempt, and help-seeking behaviors. Participants: 165,210 respondents to the American College Health Association's National College Health Assessment (NCHA), a survey administered to college students by participating institutions during Fall 2011 to Spring 2015. Methods: Single-level binary logistic regression with equality of coefficients tests and chi-square analyses. Results: The models for NSSI and suicide attempt differed slightly between student-athletes and nonathletes. Most notably, stress is a stronger correlate of NSSI (Z = 3.03, p < .01) for nonathletes while difficulties with social relationships is a stronger correlate of suicide attempt for student-athletes (Z=-3.13, p < .01). Conclusion: Our findings highlight the salience of relationship problems as a correlate with suicide attempts in student-athletes. Difficulty in romantic or other social relationships could be a marker of risk or an identifiable, actionable target for preventing future suicidal behaviors among collegiate athletes.

The Role of the Supplementary Motor Region in Overt Reading: Evidence for Differential Processing in SMA-Proper and Pre-SMA as a Function of Task Demands.

A differentiation in function between the pre-SMA (i.e., cognitive load) and the SMA-proper (i.e., motor execution) has been described (Zhang et al., Cereb Cortex 22:99-111, 2012). These differential SMA functions may be influential in overt reading tasks. The present study examined the relationships between various segments of the SMA and overt reading through the modulation of task demands in an effort to explore the complexity of the print-to-speech network. Skilled reading adults (N = 15) took part in five overt reading tasks: pure regular word reading, pure exception word reading, mixed regular word and exception word reading, go/no-go reading with nonword foils and go/no-go reading with pseudohomophone foils. Five regions of interest that spanned the pre-SMA to the SMA-proper were isolated. Behaviour-function relationships were tested to examine the associations between performance (response time) and brain activity (percent signal change). Further, the coherence between feedforward (SMA) and feedback (supramarginal gyrus) regions were explored to further refine the print-to-speech network. We found that the pre-SMA was related to cognitively demanding tasks (go/no-go with pseudohomophones), whereas the SMA-proper was related to an automatized task (pure regular words). Notably, only those tasks that required information from the feedback system (i.e., mixed word lists, go/no-go tasks) showed connections between SMA regions and the supramarginal gyrus, which is in line with the role of feedback and feedforward systems in the print-to-speech network. Together, these results support the notion that the pre-SMA and SMA-proper are sensitive to reading tasks that differentially invoke higher cognitive resources (mixed word lists, go/no-go) versus automatized articulation (pure lists), respectively. We discuss our findings in the context of print-to-speech neural networks.
