Complicated grief (CG) predicts decreased mental health over time. Furthermore, feeling connected to nature (CN) is positively associated with beneficial mental health outcomes, such as psychological wellbeing and perceived psychological resilience. Thus, we hypothesized that CN moderates the association between general grief or CG and negative mental health for bereaved people. Further, we hypothesized that one's physical exposure to nature-that is, estimated time spent in nature and greenness (i.e., vegetation) surrounding one's residential area-might moderate the association between general grief or CG and negative mental health for bereaved people. To test these hypotheses, we conducted a cross-sectional study. We sampled 153 participants who experienced the death of a close other by COVID-19 infection. Participants reported CG, general grief, anxiety symptoms, depression symptoms, CN, estimated time spent in nature, and residential area postal code via a single online survey. We estimated greenness surrounding participants' residential areas using their self-reported five-digit U.S. postal code. Cross-sectional analyses indicated that, as predicted, CN attenuated the association between CG and depression, trended toward moderating the association between CG and anxiety, and did not moderate the associations between general grief and depression or anxiety. Other variables related to the experience of nature-the estimated time an individual spends in nature and the greenness surrounding one's residential area-did not moderate the association between general grief or CG and depression or anxiety. We thus conclude that a sense of feeling connected to nature-not simply spending more time in nature or being surrounded by nature-may serve an important role in the mental health status of people experiencing complicated grief, perhaps because CN replenishes general belonging when someone significant has passed away.

Electronic sports (esports) have evolved into a major cultural phenomenon in the 21st century, mirroring traditional sports with organized, competitive play. This study investigates the prevalence of esports participation and characteristics of esports players among Norwegian adolescents. Using data from the Ungdata survey, a comprehensive web-based survey of Norwegian adolescents that includes questions on demographics, health, physical activity, social relations, and leisure activities such as gaming and esports, we analyzed responses from 70,695 students aged 16-18 years collected during 2021-2023. We conclude that about one out of twenty in the age group of 16-18 years actively engage in esports. The figure conceals significant gender differences: only 0.7% of girls, compared to 8.8% of boys, actively participate in esports. While female esports players differ noticeably from non-players on almost all indicators included in our analyses, the picture among boys reflects more similarities between esports players and other boys, than differences. Among the esports players, females almost consistently reported more negative experiences than males, including less physical socialization, lower self-rated health, higher rates of loneliness and sleeping problems, and a greater difficulty fitting in at school. Despite these negative aspects, esports players maintain close friendships similar to their non-playing peers.

The Northern Territory (NT) and Far North Queensland (FNQ) have a high proportion of Aboriginal and Torres Strait Islander women birthing who experience hyperglycaemia in pregnancy. A multi-component health systems intervention to improve antenatal and postpartum care in these regions for women with hyperglycaemia in pregnancy was implemented between 2016 and 2019. We explored health professional perspectives on the impact of the intervention on healthcare. The RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, Maintenance) underpinned this mixed-methods evaluation. Clinicians were surveyed before (n = 183) and following (n = 137) implementation. The constructs explored included usual practice and satisfaction with care pathways and communication between services. Clinicians, policymakers and the implementation team were interviewed (n = 36), exploring the impact of the health systems intervention on practice and systems of care. Survey and interview participants reported improvements in clinical practice and systems of care. Self-reported glucose screening practices improved, including the use of recommended tests (72.0% using recommended first-trimester screening test at baseline, 94.8% post-intervention, p < 0.001) and the timing of postpartum diabetes screening (28.3% screening at appropriate interval after gestational diabetes at baseline, 66.7% post-intervention, p < 0.001). Health professionals reported multiple improvements to care for women with hyperglycaemia in pregnancy following the health systems intervention.

Decompression sickness (DCS) with neurological disorders is the leading cause of major diving accidents treated in hyperbaric chambers. Exposure to high levels of CO₂ during diving is a safety concern for occupational groups at risk of DCS. However, the effects of prior exposure to CO₂ have never been evaluated. The purpose of this study was to evaluate the effect of CO₂ breathing prior to a provocative dive on the occurrence of DCS in mice. Fifty mice were exposed to a maximum CO₂ concentration of 70 hPa, i.e., 7% at atmospheric pressure, for one hour at atmospheric pressure. Another 50 mice breathing air under similar conditions served as controls. In the AIR group (control), 22 out of 50 mice showed post-dive symptoms compared to 44 out of 50 in the CO₂ group (p < 0.001). We found that CO₂ breathing is associated with a decrease in body temperature in mice and that CO₂ exposure dramatically increases the incidence of DCS (p < 0.001). More unexpectedly, it appears that the lower temperature of the animals even before exposure to the accident-prone protocol leads to an unfavorable prognosis (p = 0.046). This study also suggests that the composition of the microbiota may influence thermogenesis and thus accidentology. Depending on prior exposure, some of the bacterial genera identified in this work could be perceived as beneficial or pathogenic.

The COVID-19 pandemic exacerbated challenges in the child care industry, leading to closures and financial strain. Early care and education (ECE) providers faced reduced income, increased debt, and material hardships such as food insecurity. Using survey data collected through the Child Care Resource Center (CCRC), this study examines the association between food insecurity risk, sociodemographic factors, and pandemic-related service changes among ECE providers in California. The results showed that income, race, and increased food costs were significantly associated with a higher risk of food insecurity among ECE providers. Compared to incomes greater than USD 60,000, those earning USD 40,000-USD 49,999 and USD 50,000-USD 59,999 had higher odds of food insecurity (OR: 1.94, 95% CI: 0.683-1.86; OR: 2.12, 95% CI: 0.623-1.81, respectively). Black (OR: 1.89, 95% CI: 1.21-2.94) and multi-racial respondents (OR: 1.71, 95% CI: 1.1-2.65) had higher odds of food insecurity than white respondents. Lastly, respondents experiencing increased food costs had greater odds of food insecurity (OR: 4.52, 95% CI: 2.74-7.45). These findings suggest the need for policies and interventions aimed at increasing food access among vulnerable ECE providers. Such interventions will better protect them from financial shocks and the risk of food insecurity, and will support their crucial role in healthy child growth and development.

Acute heat illness (AHI) from extreme environmental heat exposure can lead to emergency department (ED) visits, hospitalization, and even death. While the ICD ninth revision codes for AHI have been validated in the U.S., there have been no studies on the validity of ICD-10 codes for AHI in Canada. The objective of this study was to assess the validity of an ICD-10 coding algorithm for ED encounters for AHI. We conducted a retrospective cohort study of children and adults who had ED encounters at two large academic, tertiary hospitals in London, Canada, between May and September 2014-2018. We developed an algorithm of ICD-10 codes for AHI based upon a literature review and clinical expertise. Our "gold-standard" definition of AHI was patient-reported heat exposure and documentation of at least one heat-related complaint. To establish positive predictive value (PPV), we reviewed 62 algorithm-positive records and noted which met our "gold-standard" definition. To calculate negative predictive value (NPV), sensitivity (Sn), and specificity (Sp), we randomly reviewed 964 ED records for associated ICD-10 codes and diagnoses. Two independent reviewers completed blinded data abstraction, with duplicate abstraction in 20% of the sample. Of the 62 algorithm-positive records, mean (SD) age was 38.8 (23.8) years; 37% were female. PPV was 61.3 ± 12.1% (95% CI). Of the 964 randomly selected records, mean (SD) age was 41.7 (26.5) years; 51.1% were female. The NPV was 99.7 ± 0.4%, sensitivity 25.0 ± 42.4%, and specificity 100.0 ± 0.0%. An ICD-10 coding algorithm for AHI had high specificity but was limited in sensitivity. This algorithm can be used to assemble and study cohorts of patients who have had an AHI, but may underestimate the true incidence of AHI presentations in the ED.

Emerging evidence suggests that the accuracy of a child's perceived physical competence (PPC) impacts participation in physical activity. We examined differences in active physical recreation (APR) participation based on clusters of high and low motor competence and perceptions from grades 3-5. Participants were a longitudinal sample (n = 155; 85 girls) of grade three, four, and five children. Fundamental motor skills (FMSs) were assessed using the TGMD-2, perceptions were assessed using the Self-Perception Profile for Children, and APR was measured using the Children's Assessment of Participation and Enjoyment. K-means cluster analysis was used to create four clusters per grade based on participants' FMSs and PPC z-scores. Differences in FMSs, PPC, and APR with cluster group as a factor were examined using a series of factorial ANOVAs. In each grade, participants in the high-high cluster participated in significantly more APR than those in the low-low cluster (p = 0.002 in grades three and four; p < 0.001 in grade five). Among the less accurate clusters (e.g., low FMSs with high PPC) was a trend toward positive FMSs growth among the children with higher perceptions. Results show that combinations of FMSs and PPC influence patterns of engagement or disengagement in active physical recreation persistently across middle childhood.

HIV stigma has a negative influence on antiretroviral therapy (ART) initiation and persistence and viral suppression. Immediate access to ART (RAPID ART) has been shown to accelerate viral suppression (VS) that is sustained up to one year after HIV diagnosis. Little is known about the role of RAPID ART in reducing individual-level stigma. We explored how stigma manifests in RAPID ART encounters and whether RAPID ART interventions influence individual-level HIV stigma during and in the time immediately after the diagnosis experience. We conducted in-depth interviews with 58 RAPID ART patients from three health clinics in San Francisco, CA, and Chicago, IL. Interviews were transcribed, coded, and thematically analyzed. In the results, we discuss three main themes. First, Pre-Diagnosis HIV Beliefs, which included three sub-themes: HIV is "gross" and only happens to other people; HIV (Mis)education; and People are "living long and strong" with HIV. Second, Positive and Reassuring Messages During the RAPID Experience, which included two sub-themes: Correcting Misinformation and Early Interactions with People Living with HIV. Third, The RAPID ART Process Can Disrupt Stigma. RAPID ART encounters served as a potent mechanism to disrupt internalized stigma by providing accurate information and dispelling unhelpful myths through verbal and nonverbal messages. Reducing internalized stigma and misinformation about HIV at this early stage has the potential to reduce the effect of HIV stigma on ART initiation and adherence over time.

Objective: Ensuring the sustainability of the migrant workforce requires a comprehensive understanding of the psychological challenges faced by this sub-population due to concerns about the wellbeing and financial situation of family members in their home countries. Therefore, this study investigates the factors associated with psychological distress among sub-Saharan Africa (SSA) migrant workers across Australia and Canada during the COVID-19 pandemic. Method: Data were collected from 378 first-generation migrant workers with SSA ancestry residing in Australia and Canada using the Depression Anxiety and Stress Scale 21 (DASS-21). Multivariate logistic regression analysis was used to determine socio-demographic factors associated with depression, anxiety, and stress among SSA migrants' populations. Results: Across both countries, migrants with lower levels of education were more prone to reporting feelings of depression, anxiety, and stress during the pandemic. Female participants in Australia were more likely to report feeling of depression. Participants in Australia and Canada who were separated/divorced/widowed were less likely to report stress and depression, respectively. Participants in Australia who had lived in Australia between 11 and 20 years and those between 36 and 50 years old were more likely to report feelings of depression. Participants residing in Australia whose SSA ancestry was Southern Africa/Central Africa were more likely to report anxiety. Participants in Australia who worked as part-time permanent workers and those who worked as fixed-term workers/short-term/casual workers were less likely to report anxiety. Finally, participants in Canada who reported two or more people living with them had higher odds of reporting anxiety. Conclusions: The findings from this study highlight key factors associated with SSA migrant workers' psychological distress during the pandemic. The results can inform policies and provide insight to the development of mental health intervention strategies for migrant workers to minimize similar distress during pandemics.

Background: Behavior change interventions are critical for the secondary prevention of cardiovascular disease and for reducing the risk of a repeat event or mortality. However, the effectiveness of behavior change interventions is challenged by a lack of spatiotemporal contexts, limiting our understanding of factors that influence the timing and location in which day-to-day activities occur and the maintenance of behavior change. This study explored how behavior change interventions could incorporate spatiotemporal contexts of patient activities for modifying behaviors.

Methods: A mixed-methods approach with adapted geo-ethnography techniques was used to solicit detailed descriptions of patients' day-to-day routines, including where, when, and how patients spend time. Data were gathered from patients in one cardiac intervention program in Nova Scotia, Canada, from June to September 2021.

Results: A total of 29 individuals (19 men and 10 women) between the ages of 45 and 81 and referred to the program after a cardiac event participated. The results show three key findings: (1) most patients exceeded the minimum guidelines of 30 min of daily physical activity but were sedentary for long periods of time, (2) patient time-use patterns are heterogenous and unique to contexts of individual space-time activity paths, and (3) time-use patterns reveal when, where, and how patients spend significant portions of time and opportunities for adapting patients' day-to-day health activities.

Conclusions: This study demonstrates the potential for interventions to integrate tools for collecting and communicating spatial and temporal contexts of patient routines, such as the types of activities that characterize how patients spend significant portions of time and identification of when, where, and how to encourage health-promoting changes in routine activities. Time-use patterns provide insight for tailoring behavior change interventions so that clinic-based settings are generalizable to the contexts of where, when, and how patient routines could be adapted to mitigate cardiovascular risk factors.
