Widespread Exposure to Mosquitoborne California Serogroup Viruses in Caribou, Arctic Fox, Red Fox, and Polar Bears, Canada.

Northern Canada is warming at 3 times the global rate. Thus, changing diversity and distribution of vectors and pathogens is an increasing health concern. California serogroup (CSG) viruses are mosquitoborne arboviruses; wildlife reservoirs in northern ecosystems have not been identified. We detected CSG virus antibodies in 63% (95% CI 58%-67%) of caribou (n = 517), 4% (95% CI 2%-7%) of Arctic foxes (n = 297), 12% (95% CI 6%-21%) of red foxes (n = 77), and 28% (95% CI 24%-33%) of polar bears (n = 377). Sex, age, and summer temperatures were positively associated with polar bear exposure; location, year, and ecotype were associated with caribou exposure. Exposure was highest in boreal caribou and increased from baseline in polar bears after warmer summers. CSG virus exposure of wildlife is linked to climate change in northern Canada and sustained surveillance could be used to measure human health risks.

A circumpolar parasite: Evidence of a cryptic undescribed species of sucking louse, Linognathus sp., collected from Arctic foxes, Vulpes lagopus, in Nunavut (Canada) and Svalbard (Norway).

The North has experienced unprecedented rates of warming over the past few decades, impacting the survival and development of insects and the pathogens that they carry. Since 2019, Arctic foxes from Canada (Nunavut) have been observed with fur loss inconsistent with natural shedding of fur. Adult lice were collected from Arctic foxes from Nunavut (n = 1) and Svalbard (n = 2; Norway) and were identified as sucking lice (suborder Anoplura). Using conventional PCR targeting the mitochondrial cytochrome c oxidase subunit 1 gene (cox1), lice from Canada and Svalbard were 100% similar (8 pooled samples from Nunavut and 3 pooled samples from Svalbard), indicating that there is potential gene flow between ectoparasites on Scandinavian and North American Arctic fox populations. The cox1 sequences of Arctic fox lice and dog sucking lice (Linognathus setosus) had significant differences (87% identity), suggesting that foxes may harbour a cryptic species that has not previously been recognised. Conventional PCR targeting the gltA gene for Bartonella bacteria amplified DNA from an unknown gammaproteobacteria from two pooled louse samples collected from Svalbard foxes. The amplified sequences were 100% identical to each other but were only 78% like Proteus mirabilis reported in GenBank (CP053614), suggesting that lice on Arctic foxes may carry unique microorganisms that have yet to be described.

Food-related worry and food bank use during the COVID-19 pandemic in Canada: results from a nationally representative multi-round study.

BACKGROUND: Early in the COVID-19 pandemic, nearly one in five adults in Canada worried about having enough food to meet their household's needs. Relatedly, throughout the pandemic, public messaging repeatedly urged Canadians to support food charities, including food banks. Yet few studies have examined food bank usage during the pandemic or whether food charities were widely used by Canadians worried about food access. METHODS: This study draws on four rounds of nationally representative surveying conducted during the COVID-19 pandemic between May 2020 and December 2021 among adults 18 years and older living in Canada. Descriptive statistics were used to examine rates of food-related worry during all four survey rounds. Data from the fourth survey round, collected in December 2021, were used to explore use of food-based community programs since the onset of the pandemic, including food banks. Logistic regression analyses were used to examine differences in socio-demographic and health-related characteristics between adults who did and did not report accessing food banks before and after adjusting for household income. RESULTS: Across survey rounds (n = 12,091), more than one in seven participants reported stress or worry related to having enough food to meet their household's basic needs in the previous two weeks. Yet, by December 2021, fewer than 4% of participants reported ever accessing a food bank during the pandemic. Younger age, living with a child, financial concerns due to the pandemic, two different measures of food worry, pre-existing mental health conditions, disability, LGBT2Q + identity, and racialized or Indigenous identity, were each statistically significantly associated with higher odds of using food banks even when controlling for household income. CONCLUSIONS: Despite persistently high rates of food-related worry in 2020 and 2021 in Canada, relatively few adults reported accessing food banks or other charity-based community food programs. While respondents facing social, financial, and health-related inequities and reporting food worry were more likely to use food banks, most respondents did not report food bank use, regardless of financial or demographic circumstances or experiences of food worry. Findings align with previous research indicating that more adequate and comprehensive supports are needed to alleviate food-related-worry in Canada.

Using photovoice to understand experiences of opioid use among sexual and gender minority youth in Vancouver, Canada.

In Canada, sexual and gender minority youth use opioids at disproportionately high rates. Yet, little is known about the distinct contexts of opioid use within this group, challenging capacity to develop well founded policy and practice supports. This case study aims to examine - in depth - the experiences and contexts of opioid use among a sample of four sexual and gender minority youth in Vancouver, Canada. Qualitative data from photovoice methods and in-depth, semi-structured interviews were collected in 2019. Analysis adopted a reflexive thematic approach from a critical interpretive standpoint, informed by minority stress theory. Three interconnected themes were constructed: (i) minoritised contexts of entry into and continuation of opioid use; (ii) mental health-maintaining and stress-mitigating effects of opioid use in the context of minoritisation; and (iii) intersections of stigma, violence and poverty with opioid use and minoritisation. Findings suggest that the health of sexual and gender minority youth who use opioids is shaped by minority stress and overlapping forms of structural marginalisation. They signal the need for responsive strategies that hold promise in supporting this population, including advancing integrated approaches to substance use and mental health care alongside interventions targeted towards the social and structural determinants of health.

How an emergency department is organized to provide opioid-specific harm reduction and facilitators and barriers to harm reduction implementation: a systems perspective.

BACKGROUND: The intersection of dual public health emergencies-the COVID-19 pandemic and the drug toxicity crisis-has led to an urgent need for acute care based harm reduction for unregulated opioid use. Emergency Departments (EDs) as Complex Adaptive Systems (CASs) with multiple, interdependent, and interacting elements are suited to deliver such interventions. This paper examines how the ED is organized to provide harm reduction and identifies facilitators and barriers to implementation in light of interactions between system elements. METHODS: Using a case study design, we conducted interviews with Emergency Physicians (n = 5), Emergency Nurses (n = 10), and clinical leaders (n = 5). Nine organizational policy documents were also collected. Interview data were analysed using a Reflexive Thematic Analysis approach. Policy documents were analysed using a predetermined coding structure pertaining to staffing roles and responsibilities and the interrelationships therein for the delivery of opioid-specific harm reduction in the ED. The theory of CAS informed data analysis. RESULTS: An array of system agents, including substance use specialist providers and non-specialist providers, interacted in ways that enable the provision of harm reduction interventions in the ED, including opioid agonist treatment, supervised consumption, and withdrawal management. However, limited access to specialist providers, when coupled with specialist control, non-specialist reliance, and concerns related to safety, created tensions in the system that hinder harm reduction provision with resulting implications for the delivery of care. CONCLUSIONS: To advance harm reduction implementation, there is a need for substance use specialist services that are congruent with the 24 h a day service delivery model of the ED, and for organizational policies that are attentive to discourses of specialized practice, hierarchical relations of power, and the dynamic regulatory landscape. Implementation efforts that take into consideration these perspectives have the potential to reduce harms experienced by people who use unregulated opioids, not only through overdose prevention and improving access to safer opioid alternatives, but also through supporting people to complete their unique care journeys.

Differentiating the role of alcohol in young men's use of substances with sex: A qualitative study.

BACKGROUND: Alcohol consumption is common among young men and occurs in many contexts. The sexualized substance use literature has generated some insight into the role of alcohol alongside other substances in the context of sex, though there remain opportunities for targeted and context-sensitive studies to examine the sexual practices and outcomes associated with alcohol, specifically. METHODS: This interpretive description study explores how experiences and contexts of alcohol use feature in the sexual lives of young men who use substances with sex. Data collection involved in-depth interviews conducted between 2018 and 2021 in Vancouver, Canada, with N = 76 young men (ages 18-30; mean = 23.9 years) who use substances with sex, including men with diverse sexual identities. Data were analyzed in an iterative manner through a social constructivist lens and an interpretive description framework, leveraging constant comparison techniques. FINDINGS: This analysis yielded three interconnected themes: (1) using alcohol for sexual(ity) freedoms; (2) backgrounding alcohol within a sexualized polysubstance milieu; and (3) navigating the risks and consequences of using alcohol with sex. Alcohol use was found to reduce inhibitions and support experimentation, including by facilitating the transgression of conservative or restrictive social and sexual norms. Alcohol was seldom explicitly classified as a sexualized substance, though it was evidently a widespread and normative social practice. This practice was associated with important risk and consequences, including with respect to consent, pregnancy and sexually transmitted and bloodborne infection risk, and sexual dysfunction. CONCLUSIONS: Findings from this study position alcohol as a backgrounded yet significantly influential substance that young men use with sex. The sexualized use of substances must be understood, and responded to, in a manner that is grounded in harm reduction and that considers the full spectrum of substances-inclusive of but not limited to alcohol-and associated benefits and risks that feature in young men's sexual lives. Specifically, sexual health and primary care providers working with young men should invite and open up meaningful conversation about how they may be using substances (including alcohol) with sex, while offering de-stigmatizing, sex-positive, and affirming education and supports to promote safer sex and substance use.

Young Adults' Mental Health and Unmet Service Needs in the Context of the COVID-19 Pandemic Across Canada and France.

While young adults experienced mental health challenges during the COVID-19 pandemic, little is known about how their mental health needs were subsequently met through access to mental health services (MHS). From October to December 2020, we conducted an online survey of young adults (18-29 years) living in Canada and France to investigate factors associated with unmet MHS needs. Of the 3222 participants expressing a need to access MHS (50.7% of the total sample), 58.2% in Canada and 74.8% in France reported unmet MHS needs. In both countries, those who identified as men and those who lost income due to COVID-19, were more likely to report unmet MHS needs. In Canada, participants from Quebec, those living in rural areas, and those who experienced ethno-racial discrimination had higher odds of reporting such unmet needs. Urgent investments are needed to improve access to MHS for young adults during and after the COVID-19 pandemic.

Emotional response patterns, mental health, and structural vulnerability during the COVID-19 pandemic in Canada: a latent class analysis.

BACKGROUND: The COVID-19 pandemic has contributed to increases in negative emotions such as fear, worry, and loneliness, as well as changes in positive emotions, including calmness and hopefulness. Alongside these complex emotional changes has been an inequitable worsening of population mental health, with many people experiencing suicidal ideation and using substances to cope. This study examines how patterns of co-occurring positive and negative emotions relate to structural vulnerability and mental health amid the pandemic. METHODS: Data are drawn from a cross-sectional monitoring survey (January 22-28, 2021) on the mental health of adults in Canada during the pandemic. Latent class analysis was used to group participants (N = 3009) by emotional response pattern types. Descriptive statistics, bivariate cross-tabulations, and multivariable logistic regression were used to characterize each class while quantifying associations with suicidal ideation and increased use of substances to cope. RESULTS: A four-class model was identified as the best fit in this latent class analysis. This included the most at-risk Class 1 (15.6%; high negative emotions, low positive emotions), the mixed-risk Class 2 (7.1%; high negative emotions, high positive emotions), the norm/reference Class 3 (50.5%; moderate negative emotions, low positive emotions), and the most protected Class 4 (26.8% low negative emotions, high positive emotions). The most at-risk class disproportionately included people who were younger, with lower incomes, and with pre-existing mental health conditions. They were most likely to report not coping well (48.5%), deteriorated mental health (84.2%), suicidal ideation (21.5%), and increased use of substances to cope (27.2%). Compared to the norm/reference class, being in the most at-risk class was associated with suicidal ideation (OR = 2.84; 95% CI = 2.12, 3.80) and increased use of substances to cope (OR = 4.64; 95% CI = 3.19, 6.75). CONCLUSIONS: This study identified that adults experiencing structural vulnerabilities were disproportionately represented in a latent class characterized by high negative emotions and low positive emotions amid the COVID-19 pandemic in Canada. Membership in this class was associated with higher risk for adverse mental health outcomes, including suicidal ideation and increased use of substances to cope. Tailored population-level responses are needed to promote positive coping and redress mental health inequities throughout the pandemic and beyond.

Molecular Evidence for Local Acquisition of Human Alveolar Echinococcosis in Saskatchewan, Canada.

Alveolar echinococcosis (AE) is a life-threatening parasitic disease caused by the zoonotic cestode Echinococcus multilocularis. Our goals were to confirm infection, identify species, and analyze biogeographical origin of metacestode tissues from a suspected human AE case in Saskatchewan, Canada. We conducted polymerase chain reaction (PCR) targeting the nad1 mitochondrial gene for E. multilocularis and the rrnS ribosomal RNA gene for E. granulosus and conducted haplotype analysis at the nad2 locus. Our analysis confirmed AE and indicated that sequences matched infected Saskatchewan coyotes and European E3/E4 haplotypes. The patient had no travel history outside North America. This suggests autochthonous transmission of a European-type strain.

Long-term increases in pathogen seroprevalence in polar bears (Ursus maritimus) influenced by climate change.

The influence of climate change on wildlife disease dynamics is a burgeoning conservation and human health issue, but few long-term studies empirically link climate to pathogen prevalence. Polar bears (Ursus maritimus) are vulnerable to the negative impacts of sea ice loss as a result of accelerated Arctic warming. While studies have associated changes in polar bear body condition, reproductive output, survival, and abundance to reductions in sea ice, no long-term studies have documented the impact of climate change on pathogen exposure. We examined 425 serum samples from 381 adult polar bears, collected in western Hudson Bay (WH), Canada, for antibodies to selected pathogens across three time periods: 1986-1989 (n = 157), 1995-1998 (n = 159) and 2015-2017 (n = 109). We ran serological assays for antibodies to seven pathogens: Toxoplasma gondii, Neospora caninum, Trichinella spp., Francisella tularensis, Bordetella bronchiseptica, canine morbillivirus (CDV) and canine parvovirus (CPV). Seroprevalence of zoonotic parasites (T. gondii, Trichinella spp.) and bacterial pathogens (F. tularensis, B. bronchiseptica) increased significantly between 1986-1989 and 1995-1998, ranging from +6.2% to +20.8%, with T. gondii continuing to increase into 2015-2017 (+25.8% overall). Seroprevalence of viral pathogens (CDV, CPV) and N. caninum did not change with time. Toxoplasma gondii seroprevalence was higher following wetter summers, while seroprevalences of Trichinella spp. and B. bronchiseptica were positively correlated with hotter summers. Seroprevalence of antibodies to F. tularensis increased following years polar bears spent more days on land, and polar bears previously captured in human settlements were more likely to be seropositive for Trichinella spp. As the Arctic has warmed due to climate change, zoonotic pathogen exposure in WH polar bears has increased, driven by numerous altered ecosystem pathways.

A portrait of the early and differential mental health impacts of the COVID-19 pandemic in Canada: Findings from the first wave of a nationally representative cross-sectional survey.

Evidence on the population-level mental health impacts of COVID-19 are beginning to amass; however, to date, there are significant gaps in our understandings of whose mental health is most impacted, how the pandemic is contributing to widening mental health inequities, and the coping strategies being used to sustain mental health. The first wave of a repeated cross-sectional monitoring survey was conducted between May 14-29, 2020 to assess the mental health impacts of the pandemic and to identify the disproportionate impacts on populations or groups identified as experiencing increased risks due to structural vulnerability and pre-existing health and social inequities. Respondents included a nationally representative probability sample (n = 3000) of Canadian adults 18 years and older. Overall, Canadian populations are experiencing a deterioration in mental health and coping due to the pandemic. Those who experience health, social, and/or structural vulnerabilities due to pre-existing mental health conditions, disability, income, ethnicity, sexuality, and/or gender are more likely to endorse mental health deterioration, challenging emotions, and difficulties coping. This monitoring study highlights the differential mental health impacts of the pandemic for those who experience health, social, and structural inequities. These data are critical to informing responsive, equity-oriented public health, and policy responses in real-time to protect and promote the mental health of those most at risk during the pandemic and beyond.

"It's a Bit of a Double-Edged Sword": Motivation and Personal Impact of Bereaved Mothers' Advocacy for Drug Policy Reform.

North America's overdose crisis is an urgent public health issue that has resulted in thousands of deaths. As the crisis began to take hold across Canada in 2016, bereaved parents, mainly mothers, emerged as vocal advocates for drug policy reform and harm reduction, using their stories to challenge the stigma of drug-related death. In 2017, we launched a qualitative research partnership with leading family organizations in Canada, conducting interviews with 43 mothers whose children had died from substance use, to understand their experiences of drug policy advocacy. Our findings showed that participants' motivations for engaging in advocacy were rooted in their experiences of grief, and that advocacy led to feelings of empowerment and connection to others. Our research suggests that advocacy can be cathartic and associated with healing from grief, but that "going public" in sharing a family story of substance use death can also have a considerable personal cost.

Exposure of the Gulf of St. Lawrence grey seal Halichoerus grypus population to potentially zoonotic infectious agents.

The population of grey seals Halichoerus grypus in Canadian waters is currently used as a commercial source of meat for human consumption. As with domestic livestock, it is important to understand the occurrence in these seals of infectious agents that may be of public health significance and thus ensure appropriate measures are in place to avoid zoonotic transmission. This study examined the prevalence of antibodies against Brucella spp., Erysipelothrix rhusiopathiae, 6 serovars of Leptospira interrogans, and Toxoplasma gondii in 59 grey seals and determined by polymerase chain reaction (PCR) the presence of these potentially zoonotic agents in specific organs and tissues of seropositive animals. The presence of encysted Trichinella spp. larvae was also investigated by digestion of tongue, diaphragm and other muscle samples, but none were detected. Seroprevalence against Brucella spp. and E. rhusiopathiae was low (5 and 3%, respectively). All 59 seals tested had antibodies against L. interrogans, but no carrier of this bacterium was detected by PCR. Seroprevalence against T. gondii was 53%, and DNA of this protozoan was detected by PCR in 11/30 (37%) seropositive animals. Standard sanitary measures mandatory for commercialization of meat products for human consumption should greatly reduce the potential for exposure to these infectious agents. However, special consideration should be given to freezing seal meat for at least 3 d to ensure destruction of tissue cysts of T. gondii.

Use of Asynchronous Virtual Mental Health Resources for COVID-19 Pandemic-Related Stress Among the General Population in Canada: Cross-Sectional Survey Study.

BACKGROUND: The COVID-19 pandemic has resulted in profound mental health impacts among the general population worldwide. As many in-person mental health support services have been suspended or transitioned online to facilitate physical distancing, there have been numerous calls for the rapid expansion of asynchronous virtual mental health (AVMH) resources. These AVMH resources have great potential to provide support for people coping with negative mental health impacts associated with the pandemic; however, literature examining use prior to COVID-19 illustrates that the uptake of these resources is consistently low. OBJECTIVE: The aim of this paper is to examine the use of AVMH resources in Canada during the COVID-19 pandemic among the general population and among a participant subgroup classified as experiencing an adverse mental health impact related to the pandemic. METHODS: Data from this study were drawn from the first wave of a large multiwave cross-sectional monitoring survey, distributed from May 14 to 29, 2020. Participants (N=3000) were adults living in Canada. Descriptive statistics were used to characterize the sample, and bivariate cross-tabulations were used to examine the relationships between the use of AVMH resources and self-reported indicators of mental health that included a range of emotional and coping-related responses to the pandemic. Univariate and fully adjusted multivariate logistic regression models were used to examine associations between sociodemographic and health-related characteristics and use of AVMH resources in the subgroup of participants who reported experiencing one or more adverse mental health impacts identified in the set of self-reported mental health indicators. RESULTS: Among the total sample, 2.0% (n=59) of participants reported accessing AVMH resources in the prior 2 weeks to cope with stress related to the COVID-19 pandemic, with the highest rates of use among individuals who reported self-harm (n=5, 10.4%) and those who reported coping "not well" with COVID-19-related stress (n=22, 5.5%). Within the subgroup of 1954 participants (65.1% of the total sample) who reported an adverse mental health impact related to COVID-19, 54 (2.8%) reported use of AVMH resources. Individuals were more likely to have used AVMH resources if they had reported receiving in-person mental health supports, were connecting virtually with a mental health worker or counselor, or belonged to a visible minority group. CONCLUSIONS: Despite substantial government investment into AVMH resources, uptake is low among both the general population and individuals who may benefit from the use of these resources as a means of coping with the adverse mental health impacts of the COVID-19 pandemic. Further research is needed to improve our understanding of the barriers to use.

Equipping youth for meaningful policy engagement: an environmental scan.

To better address the mental health and substance use crises facing youth globally, a comprehensive approach, inclusive of mental health promotion is needed. A key component of mental health promotion is policy intervention to address the social and structural determinants of health. Importantly, youth should be engaged in these efforts to maximize relevancy and impact. Yet, while there is growing interest in the inclusion of youth in the policymaking process, there is a paucity of guidance on how to do this well. This environmental scan reports findings from a comprehensive search of academic and grey literature that was conducted using the electronic databases: CINAHL, ERIC, MEDLINE, PsycINFO, Google Scholar, and Google. Search terms included variations of 'youth*', 'educat*', 'engage*', 'policy' and 'policy training'. Thirteen English language training programmes met inclusion criteria. Analysis identified marked differences in programme philosophy and focus by geographic region and highlights the need for enhanced evaluation and impact measurement moving forward. This paper makes a needed contribution to the evidence-base guiding this key mental health promotion strategy, which holds the potential to address critical gaps in approaches to youth mental health and substance use.

"Am I gonna get in trouble for acknowledging my will to be safe?": Identifying the experiences of young sexual minority men and substance use in the context of an opioid overdose crisis.

BACKGROUND: North America and other parts of the globe are in the midst of a public health emergency related to opioid overdoses and a highly contaminated illicit drug supply. Unfortunately, there is a substantial gap in our understandings about how this crisis affects key populations not conventionally identified within overdose-related surveillance data. This gap is particularly pronounced for gay, bisexual, and other men who have sex with men (sexual minority men)-a population that experiences substance use-related inequities across adolescence and young adulthood. METHODS: We draw on in-depth semi-structured interviews conducted in 2018 with a diverse sample (N = 50) of sexual minority men ages 15-30 who use substances and live in Vancouver, Canada, to identify how patterns and contexts of substance use are occurring in the context of the opioid overdose crisis. RESULTS: Our analysis revealed three themes: awareness, perceptions, and experiences of risk; strategies to mitigate risk; and barriers to safer substance use. First, participants described how they are deeply impacted by the contaminated illicit drug supply, and how there is growing apprehension that fatal and non-fatal overdose risk is high and rising. Second, participants described how procuring substances from "trustworthy" drug suppliers and other harm reduction strategies (e.g., drug checking technologies, Naloxone kits, not using alone) could reduce overdose risk. Third, participants described how interpersonal, service-related, and socio-structural barriers (e.g., drug criminalization and the lack of a regulated drug supply) limit opportunities for safer substance use. CONCLUSIONS: Equity-oriented policies and programming that can facilitate opportunities for safer substance use among young sexual minority men are critically needed, including community- and peer-led initiatives, access to low-barrier harm reduction services within commonly frequented social spaces (e.g., Pride, night clubs, bathhouses), nonjudgmental and inclusive substance use-related health services, the decriminalization of drug use, and the provision of a safe drug supply.

Undergraduate students' perspectives on pursuing a career in mental health nursing following practicum experience.

AIMS AND OBJECTIVES: The purpose of this study was to explore how undergraduate students perceive and make decisions regarding mental health nursing as a career following completion of an inpatient mental health practicum. BACKGROUND: Among nursing students, mental health is consistently perceived as the least desirable nursing career path. However, evidence to explain why this is the case remains limited, with a lack of research exploring students' experiences of mental health settings and how these experiences influence their perceptions of a mental health nursing career. This knowledge gap limits strategies to support nurses' selection of mental health nursing as a career path, contributing to a global shortage of mental health nurses. DESIGN: This study used a qualitative narrative inquiry design. METHODS: In-depth interviews (N = 15) were conducted with undergraduate nursing students to explore their experiences of mental health practicums. Participants had all completed a 6-week practicum in inpatient mental health settings in urban hospitals. Reporting follows COREQ guidelines. RESULTS: Nursing students' decisions to not choose a career in mental health nursing were influenced by negative practicum experiences, including the institutional environments of the inpatient mental health settings and witnessing of harmful nursing practices. These factors were identified as barriers to pursuing a career in mental health nursing. However, students expressed desire to continue to work with clients with mental health challenges and aimed to pursue nursing careers that preserve this opportunity in different healthcare settings. CONCLUSIONS: These findings expand upon existing literature that frequently positions nursing students as "uninterested" in mental health nursing and offers insights that can contribute to addressing global mental health nursing shortages. RELEVANCE TO CLINICAL PRACTICE: This study highlights the need for mental health nurses, nursing leaders, and educators to recognise and respond to students' difficult experiences in the inpatient mental health setting during practicums.

Leveraging Nurses to Improve Care for Patients with Concurrent Disorders in Inpatient Mental Health Settings: A Scoping Review.

Objective: Several challenges have been identified for patients with concurrent disorders and the providers that care for them, contributing to a pressing need for interventions to improve outcomes, particularly within inpatient mental health settings. Methods: A systematic search of peer-reviewed literature was conducted using four online databases: CINAHL, MEDLINE (Ovid), PsycInfo and Web of Science. Articles were selected based on inclusion criteria and additional articles were identified through hand searches. Study details were charted and qualitative synthesis was conducted. Results: Thirty two articles met inclusion criteria. A substantial focus within the literature was education, with higher levels of education shown to improve healthcare provider attitudes and practices. Within this overarching focus, four themes were identified: 1) education as an intervention to improve attitudes and increase confidence and knowledge; 2) strategies to support practice change, including interventions aimed at clinical leaders and methods to address substance use among inpatients; 3) frameworks to guide care; and 4) opportunities to expand nursing scope of practice. Conclusions: Given the substantial evidence indicating that education improves nurses' knowledge, attitudes and practices, there is great promise in expanding educational intervention opportunities for nurses to improve care and outcomes for patients with concurrent disorders-a priority patient population.

Associations between adiposity measures and 25-hydroxyvitamin D among police officers.

OBJECTIVE: Studies show that serum levels of 25-hydroxyvitamin D (25(OH)D), a biomarker for vitamin D status, are lower in persons with higher adiposity levels and that police officers have been found to have a high prevalence of obesity. The purpose of this study was to examine relationships between several adiposity measures and 25(OH)D, and also compare those measures to determine the best one that predicts insufficiency of 25(OH)D (<20 ng/mL) among police officers in the Northeast area of the United States. METHODS: Participants were 281 police officers (71.5% men) from the Buffalo Cardio-Metabolic Occupational Police Stress Study (2011-2016). Associations of body mass index (BMI), abdominal height (AbHt), waist circumference (WC), WC-to-height ratio (WCHtR), percent body fat (PBF), and fat mass index (FMI) with 25(OH)D were obtained using multiple regression models after adjustment for age, race/ethnicity, season, multivitamin supplement use, and high-density lipoprotein cholesterol. The area under the curve (AUC) was used to evaluate the predictive ability of each adiposity measure to identify insufficient 25(OH)D concentrations. RESULTS: The prevalence of obesity (BMI ≥ 30) was 50.7% in men and 21.3% in women. Mean levels of 25(OH)D were 32.4 ng/mL in men and 34.4 ng/mL in women. After adjustment for covariates, PBF and FMI among men were inversely associated with 25(OH)D: PBF (ß ± SE = -2.40 ± 1.01, P = .018); FMI (-2.21 ± 0.93, .018). Among women, no adiposity measure was associated with 25(OH)D. PBF was the best predictor of insufficient 25(OH)D concentrations regardless of gender (AUC = 0.878). CONCLUSION: Adiposity measures were inversely associated with 25(OH)D, but differed between female and male officers.

"You can't chain a dog to a porch": a multisite qualitative analysis of youth narratives of parental approaches to substance use.

BACKGROUND: Reducing harms of youth substance use is a global priority, with parents identified as a key target for efforts to mitigate these harms. Much of the research informing parental responses to youth substance use are grounded in abstinence and critiqued as ineffective and unresponsive to youth contexts. Parental provision of substances, particularly alcohol, is a widely used approach, which some parents adopt in an attempt to minimize substance use harms; however, research indicates that this practice may actually increase harms. There is an absence of research exploring youth perspectives on parental approaches to substance use or the approaches youth find helpful in minimizing substance use-related harms. METHODS: This paper draws on interviews with youth aged 13-18 (N = 89) conducted within the Researching Adolescent Distress and Resilience (RADAR) study in three communities in British Columbia, Canada. An ethnographic approach was used to explore youth perspectives on mental health and substance use within intersecting family, social, and community contexts. This analysis drew on interview data relating to youth perspectives on parental approaches to substance use. A multisite qualitative analysis (MSQA) was conducted to examine themes within each research site and between all three sites to understand how youth perceive and respond to parental approaches to substance use in different risk environment contexts. RESULTS: Within each site, youths' experiences of and perspectives on substance use were shaped by their parents' approaches, which were in turn situated within local social, geographic, and economic community contexts. Youth descriptions of parental approaches varied by site, though across all sites, youth articulated that the most effective approaches were those that resonated with the realities of their lives. Zero-tolerance approaches were identified as unhelpful and unresponsive, while approaches that were aligned with harm reduction principles were viewed as relevant and supportive. CONCLUSIONS: Youth perspectives illustrate that parental approaches to substance use that are grounded in harm reduction principles resonate with young people's actual experiences and can support the minimization of harms associated with substance use. Evidence-based guidance is needed that supports parents and young people in adopting more contextually responsive harm reduction approaches to youth substance use.
