Prevalence and Correlates of Providing and Receiving Assistance With the Transition to Injection Drug Use.

Preventing the transition to injection drug use is an important public health goal, as people who inject drugs (PWID) are at high risk for overdose and acquisition of infectious disease. Initiation into drug injection is primarily a social process, often involving PWID assistance. A better understanding of the epidemiology of this phenomenon would inform interventions to prevent injection initiation and to enhance safety when assistance is provided. We conducted a systematic review of the literature to 1) characterize the prevalence of receiving (among injection-naive persons) and providing (among PWID) help or guidance with the first drug injection and 2) identify correlates associated with these behaviors. Correlates were organized as substance use behaviors, health outcomes (e.g., human immunodeficiency virus infection), or factors describing an individual's social, economic, policy, or physical environment, defined by means of Rhodes' risk environments framework. After screening of 1,164 abstracts, 57 studies were included. The prevalence of receiving assistance with injection initiation (help or guidance at the first injection) ranged 74% to 100% (n = 13 estimates). The prevalence of ever providing assistance with injection initiation varied widely (range, 13%-69%; n = 13 estimates). Injecting norms, sex/gender, and other correlates classified within Rhodes' social risk environment were commonly associated with providing and receiving assistance. Nearly all PWID receive guidance about injecting for the first time, whereas fewer PWID report providing assistance. Substantial clinical and statistical heterogeneity between studies precluded meta-analysis, and thus local-level estimates may be necessary to guide the implementation of future psychosocial and sociostructural interventions. Further, estimates of providing assistance may be downwardly biased because of social desirability factors.

History of Childhood Abuse in Populations Incarcerated in Canada: A Systematic Review and Meta-Analysis.

BACKGROUND: A history of childhood abuse may affect people's health and criminal justice system involvement. Understanding the prevalence of childhood abuse among individuals in prison is important to inform effective and appropriate correctional services. OBJECTIVES: To review and summarize data on the prevalence of childhood abuse among people experiencing imprisonment in Canada. SEARCH METHODS: We searched for studies in bibliographic indexes, reference lists, and gray literature, and we consulted experts. SELECTION CRITERIA: We included studies published since 1987 that reported data on prevalence of a history of abuse before the age of 18 years among people in Canadian prisons, including any abuse, physical abuse, sexual abuse, emotional abuse, and neglect. DATA COLLECTION AND ANALYSIS: Two authors independently reviewed titles and abstracts for eligibility and reviewed full texts for eligibility. Analyses included summary estimates and meta-regression with random effects. MAIN RESULTS: The search identified 1429 records. We included 34 unique studies in our review and 29 nonoverlapping studies in our meta-analysis. The summary prevalence for any type of childhood abuse was 65.7% (95% confidence interval [CI] = 52.6, 77.7; range = 56.2% to 75.0%) among women; only one study reported the prevalence among men (35.5%). The summary prevalence of sexual abuse was 50.4% (95% CI = 33.5, 67.2; range = 9.9% to 77.3%) among women and 21.9% (95% CI = 15.7, 28.8; range = 8.3% to 55.6%) among men. The prevalence of neglect was 51.5% (95% CI = 43.1, 59.7; range = 45.5% to 65.1%) among women and 42.0% (95% CI = 12.7, 74.6; range = 6.8% to 99.0%) among men. The prevalence of physical abuse was 47.7% (95% CI = 41.3, 54.0; range = 16.3% to 83.0%), and the prevalence of emotional abuse was 51.5% (95% CI = 34.8, 67.9; range = 8.7% to 96.0%); we did not find differences according to gender. Prevalence estimates for all types of abuse showed high and unexplained variability across studies. CONCLUSIONS: Half of people in prisons in Canada experienced abuse in childhood. Public Health Implications. Prisons should incorporate trauma-informed approaches. Research is required to understand the association between a history of childhood abuse and criminal justice system involvement and to prevent childhood abuse and mitigate its adverse effects.

The use of self-management strategies for problem gambling: a scoping review.

BACKGROUND: Problem gambling (PG) is a serious public health concern that disproportionately affects people experiencing poverty, homelessness, and multimorbidity including mental health and substance use concerns. Little research has focused on self-help and self-management in gambling recovery, despite evidence that a substantial number of people do not seek formal treatment. This study explored the literature on PG self-management strategies. Self-management was defined as the capacity to manage symptoms, the intervention, health consequences and altered lifestyle that accompanies a chronic health concern. METHODS: We searched 10 databases to identity interdisciplinary articles from the social sciences, allied health professions, nursing and psychology, between 2000 and June 28, 2017. We reviewed records for eligibility and extracted data from relevant articles. Studies were included in the review if they examined PG self-management strategies used by adults (18+) in at least a subset of the sample, and in which PG was confirmed using a validated diagnostic or screening tool. RESULTS: We conducted a scoping review of studies from 2000 to 2017, identifying 31 articles that met the criteria for full text review from a search strategy that yielded 2662 potential articles. The majority of studies examined self-exclusion (39%), followed by use of workbooks (35%), and money or time limiting strategies (17%). The remaining 8% focused on cognitive, behavioural and coping strategies, stress management, and mindfulness. CONCLUSIONS: Given that a minority of people with gambling concerns seek treatment, that stigma is an enormous barrier to care, and that PG services are scarce and most do not address multimorbidity, it is important to examine the personal self-management of gambling as an alternative to formalized treatment.

Problem Gambling and Delinquent Behaviours Among Adolescents: A Scoping Review.

Despite many studies indicating an association between problem gambling and delinquent behaviours among adolescents, there has been no effort to systematically analyze the state of the literature on this relationship. To fill this gap, we conducted a scoping review of the literature published between 2000 and 2016 on problem gambling and delinquent behaviours among adolescents. We searched twelve databases and reviewed reference lists to identify eligible studies. Search terms included a combination of medical subject headings and keywords for gambling, youth, and delinquency, which were combined with the Boolean operator "AND". 1795 studies were identified through the literature search. Nine studies were eligible for inclusion. All of the studies were conducted in North America, with primarily male participants, and most of the data were cross-sectional. No qualitative studies met the inclusion criteria. Screening tools used to measure problem gambling were inconsistent, making comparisons across studies difficult. We found a consistent moderate to strong association between problem gambling and delinquent behaviour. Only one study presented associations by socio-economic status and none considered gender, sex or ethnic differences. Studies in the review showed that problem gambling is associated with both violent and non-violent behaviours among adolescents. These associations may suggest that problem gambling and delinquent behaviours have common risk factors and reflect a syndrome of risky behaviours best targeted through prevention and treatment that is holistic and considers the context in which the youth is situated. Further research is warranted to better understand the relationship between problem gambling and delinquent behaviours.

Amiodarone Versus Lidocaine for Pediatric Cardiac Arrest Due to Ventricular Arrhythmias: A Systematic Review.

OBJECTIVE: We performed a systematic review as part of the International Liaison Committee on Resuscitation process to create a consensus on science statement regarding amiodarone or lidocaine during pediatric cardiac arrest for the 2015 International Liaison Committee on Resuscitation's Consensus on Science and Treatment Recommendations. DATA SOURCES: Studies were identified from comprehensive searches in PubMed, Embase, and the Cochrane Library. STUDY SELECTION: Studies eligible for inclusion were randomized controlled and observational studies on the relative clinical effect of amiodarone or lidocaine in cardiac arrest. DATA EXTRACTION: Studies addressing the clinical effect of amiodarone versus lidocaine were extracted and reviewed for inclusion and exclusion criteria by the reviewers. Studies were rigorously analyzed thereafter. DATA SYNTHESIS: We identified three articles addressing lidocaine versus amiodarone in cardiac arrest: 1) a prospective study assessing lidocaine versus amiodarone for refractory ventricular fibrillation in out-of-hospital adults; 2) an observational retrospective cohort study of inpatient pediatric patients with ventricular fibrillation or pulseless ventricular tachycardia who received lidocaine, amiodarone, neither or both; and 3) a prospective study of ventricular tachycardia with a pulse in adults. The first study showed a statistically significant improvement in survival to hospital admission with amiodarone (22.8% vs 12.0%; p = 0.009) and a lack of statistical difference for survival at discharge (p = 0.34). The second article demonstrated 44% return of spontaneous circulation for amiodarone and 64% for lidocaine (odds ratio, 2.02; 1.36-3.03) with no statistical difference for survival at hospital discharge. The third article demonstrated 48.3% arrhythmia termination for amiodarone versus 10.3% for lidocaine (p < 0.05). All were classified as lower quality studies without preference for one agent. CONCLUSIONS: The confidence in effect estimates is so low that International Liaison Committee on Resuscitation felt that a recommendation to use of amiodarone over lidocaine is too speculative; we suggest that amiodarone or lidocaine can be used in the setting of pulseless ventricular tachycardia/ventricular fibrillation in infants and children.

Gamblers Anonymous as a Recovery Pathway: A Scoping Review.

Given the preponderance of Gamblers Anonymous (GA), there has been relatively little effort to explore the existing evidence base on its effectiveness as a recovery approach for problem gambling. To remedy this gap in the literature we conducted a scoping review of the literature on mutual aid for individuals experiencing problem gambling published between 2002 and 2015. We searched 13 databases and reviewed reference lists and websites of relevant organizations. We reviewed records for eligibility and extracted relevant data from eligible articles. Three reviewers independently assessed the methodological quality of the included studies using the Mixed Methods Appraisal Tool. We identified 17 studies in 25 publications that were eligible for inclusion. Most studies were conducted in the United States, were cross-sectional in design, and involved both male and female adult participants. Results indicate that the evidence for the effectiveness of GA either as a control condition or in conjunction with formal treatment or medication is inconsistent. An emphasis on patience, using the Serenity Prayer as a way to gain acceptance of financial matters and reality, and absolute assertion of identity as a "compulsive gambler" were identified as important aspects of GA's recovery culture. There is a need for large-scale randomized controlled trials to determine GA's effectiveness, as well as research exploring the mechanisms through which GA works, barriers to GA as a recovery approach, and the status of women in the fellowship.

COVID-related disruptions and adaptations to prison-based mental health and substance use services: a narrative review.

PURPOSE: Public health experts and advocates have long raised concerns about the pandemic preparedness of prison systems worldwide - an issue that became increasingly salient at the start of the COVID-19 pandemic. People in prison experience poorer health outcomes compared to the general population, making timely access to adequate health services in prison critical for their health and wellbeing. This study aims to identify the extent of the literature on initial changes in mental health and substance use services for people in prison during the COVID-19 pandemic, summarize and synthesize the findings and identify areas in need of further study. DESIGN/METHODOLOGY/APPROACH: The authors conducted a review of the academic literature published internationally in English between 2019 and December 1, 2020 to describe the disruptions and adaptations to mental health and substance use services in prisons during the onset of the COVID-19 pandemic. FINDINGS: The authors found that mental health and substance use services in prisons around the world were widely disrupted due to the COVID-19 pandemic - predominantly consisting of the complete suspension of services, discontinuation of transfers to off-site treatment sites and limitations on service capacity. Adaptations ranged from virtual service delivery and changes to treatment dispensation processes to information sessions on overdose prevention. ORIGINALITY/VALUE: To the best of the authors' knowledge, this is the first review to examine the nature and extent of the literature on delivery of mental health and substance use services in prisons during the COVID-19 pandemic.

Role of Antioxidant Therapy in the Treatment and Prognosis of COVID-19: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Background: A significant aspect of the SARS-CoV-2 pathology involves oxidative stress, characterized by an imbalance between the production of harmful free radicals and the body's antioxidant defenses. With the ongoing evolution of SARS-CoV-2, the investigation into non-virus-specific therapeutic options, such as antioxidant therapy, has gained importance. Objectives: This systematic review and meta-analysis aimed to summarize data from randomized control trials (RCTs) to evaluate the effectiveness and safety of antioxidant therapy in patients with SARS-CoV-2 infection. Methods: We searched the peer-reviewed indexed literature on MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, EMBASE, International Pharmaceutical Abstracts, and Scopus, from inception to July 2023. Results: The search identified 3306 articles from which 25 were included for quantitative synthesis, with 5 studies eligible for meta-analysis. Antioxidant therapies included zinc, vitamin A, vitamin C, and combination treatments. Zinc interventions showed mixed results regarding intensive care unit admissions and hospital stays. Vitamin A studies indicated improvements in inflammatory markers. Vitamin C studies displayed inconsistent effects on clinical improvement and hospitalization. Combination treatments suggested benefits in symptom clearance and cytokine storm reduction. Meta-analysis of vitamin C studies found no significant difference in C-reactive protein concentrations (-0.50; 95% CI: -3.63, 2.63; I2 = 0%), intensive care unit stay duration (pooled mean difference: 1.44; 95% CI: 0.07, 2.81; I2 = 0%), or mortality (pooled odds ratio: 0.55; 95% CI: 0.28, 1.09; I2 = 0%), with a slight trend favoring reduced hospitalization duration (pooled mean difference: -2.37; 95% CI: -2.99, -1.76; I2 = 49%). Of the 25 studies, 8 were high quality with low bias, 6 had some concerns, and 11 were low quality with high bias. Conclusions: The review presents mixed efficacy of antioxidant therapies for SARS-CoV-2, with some studies indicating potential benefits. Further well-designed large-scale RCTs are warranted to determine the definitive role of antioxidants in SARS-CoV-2 treatment.This systematic review was registered at PROSPERO as CRD42023430805.

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.

Guidelines and recommendations about virtual mental health services from high-income countries: a rapid review.

OBJECTIVES: This study reviewed existing recommendations for virtual mental healthcare services through the quadruple aim framework to create a set of recommendations on virtual healthcare delivery to guide the development of Canadian policies on virtual mental health services. DESIGN: We conducted a systematic rapid review with qualitative content analysis of data from included manuscripts. The quadruple aim framework, consisting of improving patient experience and provider satisfaction, reducing costs and enhancing population health, was used to analyse and organise findings. METHODS: Searches were conducted using seven databases from 1 January 2010 to 22 July 2022. We used qualitative content analysis to generate themes. RESULTS: The search yielded 40 articles. Most articles (85%) discussed enhancing patient experiences, 55% addressed provider experiences and population health, and 25% focused on cost reduction. Identified themes included: screen patients for appropriateness of virtual care; obtain emergency contact details; communicate transparently with patients; improve marginalised patients' access to care; support health equity for all patients; determine the cost-effectiveness of virtual care; inform patients of insurance coverage for virtual care services; increase provider training for virtual care and set professional boundaries between providers and patients. CONCLUSIONS: This rapid review identified important considerations that can be used to advance virtual care policy to support people living with mental health conditions in a high-income country.

Systematic review of Indigenous cultural safety training interventions for healthcare professionals in Australia, Canada, New Zealand and the United States.

OBJECTIVE: To synthesise and appraise the design and impact of peer-reviewed evaluations of Indigenous cultural safety training programmes and workshops for healthcare workers in Australia, Canada, New Zealand and/or the United States. DESIGN: Systematic review. DATA SOURCES: Ovid Medline, Embase, PsycINFO, CINAHL, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Bibliography of Indigenous Peoples in North America, Applied Social Sciences Index & Abstracts, ERIC (Education Resources Information Center), International Bibliography of the Social Sciences, ProQuest Dissertations & Theses Global, Sociological Abstracts, and Web of Science's Social Sciences Citation Index and Science Citation Index from 1 January 2006 to 12 May 2022. ELIGIBILITY CRITERIA: Studies that evaluated the outcomes of educational interventions for selecting studies: designed to improve cultural safety, cultural competency and/or cultural awareness for non-Indigenous adult healthcare professionals in Canada, Australia, New Zealand or the United States. DATA EXTRACTION AND SYNTHESIS: Our team of Indigenous and allied scientists tailored existing data extraction and quality appraisal tools with input from Indigenous health service partners. We synthesised the results using an iterative narrative approach. RESULTS: 2442 unique titles and abstracts met screening criteria. 13 full texts met full inclusion and quality appraisal criteria. Study designs, intervention characteristics and outcome measures were heterogeneous. Nine studies used mixed methods, two used qualitative methods and two used quantitative methods. Training participants included nurses, family practice residents, specialised practitioners and providers serving specific subpopulations. Theoretical frameworks and pedagogical approaches varied across programmes, which contained overlapping course content. Study outcomes were primarily learner oriented and focused on self-reported changes in knowledge, awareness, beliefs, attitudes and/or the confidence and skills to provide care for Indigenous peoples. The involvement of local Indigenous communities in the development, implementation and evaluation of the interventions was limited. CONCLUSION: There is limited evidence regarding the effectiveness of specific content and approaches to cultural safety training on improving non-Indigenous health professionals' knowledge of and skills to deliver quality, non-discriminatory care to Indigenous patients. Future research is needed that advances the methodological rigour of training evaluations, is focused on observed clinical outcomes, and is better aligned to local, regional,and/or national Indigenous priorities and needs.

Interventions Designed to Increase the Uptake of Lung Cancer Screening: An Equity-Oriented Scoping Review.

Introduction: Participation in lung cancer screening (LCS) is lower in populations with the highest burden of lung cancer risk (through the social patterning of smoking behavior) and lowest levels of health care utilization (through structurally inaccessible care) leading to a widening of health inequities. Methods: We conducted a scoping review using the Arksey and O'Malley methodological framework to inform equitable access to LCS by illuminating knowledge and implementation gaps in interventions designed to increase the uptake of LCS. We comprehensively searched for LCS interventions (Ovid Medline, Excerpta Medica database, the Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, and Scopus from 2000 to June 22, 2021) and included peer-reviewed articles and gray literature published in the English language that describe an intervention designed to increase the uptake of LCS, charted data using our previously published tool and conduced a health equity analysis to determine the intended-unintended and positive-negative outcomes of the interventions for populations experiencing the greatest inequities. Results: Our search yielded 3572 peer-reviewed articles and 54,292 pieces of gray literature. Ultimately, we included 35 peer-reviewed articles and one gray literature. The interventions occurred in the United States, United Kingdom, Japan, and Italy, focusing on shared decision-making, the use of electronic health records as reminders, patient navigation, community-based campaigns, and mobile computed tomography scanners. We developed an equity-oriented LCS framework and mapped the dimensions and outcomes of the interventions on access to LCS on the basis of approachability, acceptability, availability, affordability, and appropriateness of the intervention. No intervention was mapped across all five dimensions. Most notably, knowledge and implementation gaps were identified in dimensions of acceptability, availability, and affordability. Conclusions: Interventions that were most effective in improving access to LCS targeted priority populations, raised community-level awareness, tailored materials for sociocultural acceptability, did not depend on prior patient engagement/registration with the health care system, proactively considered costs related to participation, and enhanced utilization through informed decision-making.

Sexual health promotion for sexual and gender minorities in primary care: a scoping review protocol.

INTRODUCTION: Sexual and gender minorities (SGMs) face health disparities related to systemic discrimination and barriers to sexual health. Sexual health promotion encompasses strategies that enable individuals, groups and communities to make informed decisions regarding their sexual well-being. Our objective is to describe the existing sexual health promotion interventions tailored for SGMs within the primary care context. METHODS AND ANALYSIS: We will conduct a scoping review and search for articles in 12 medical and social science academic databases on interventions that are targeted towards SGMs in the primary care context in industrialised countries. Searches were conducted on 7 July 2020 and 31 May 2022. We defined sexual health interventions in the inclusion framework as: (1) promote positive sexual health, or sex and relationship education; (2) reduce the incidence of sexually transmitted infections; (3) reduce unintended pregnancies; or (4) change prejudice, stigma and discrimination around sexual health, or increase awareness surrounding positive sex. Two independent reviewers will select articles meeting inclusion criteria and extract data. Participant and study characteristics will be summarised using frequencies and proportions. Our primary analysis will include a descriptive summary of key interventional themes from content and thematic analysis. Gender-based Analysis Plus will be used to stratify themes based on gender, race, sexuality and other identities. The secondary analysis will include the use of the Sexual and Gender Minority Disparities Research Framework to analyse the interventions from a socioecological perspective. ETHICS AND DISSEMINATION: No ethical approval is required for a scoping review. The protocol was registered on the Open Science Framework Registries (https://doi.org/10.17605/OSF.IO/X5R47). The intended audiences are primary care providers, public health, researchers and community-based organisations. Results will be communicated through peer-reviewed publication, conferences, rounds and other opportunities to reach primary care providers. Community-based engagement will occur through presentations, guest speakers, community forums and research summary handouts.

Using financial incentives to improve health service engagement and outcomes of adults experiencing homelessness: A scoping review of the literature.

People experiencing homelessness (PEH) have high rates of acute and chronic health conditions, complex support needs and often face multiple barriers to accessing health services. Financial incentive (FI) interventions have been found effective in improving service engagement and health outcomes for a range of health conditions, populations and settings, but little is known about their impact on PEH. We conducted a scoping review to explore the impact of FI interventions on treatment retention, adherence and other health outcomes of PEH. We searched seven electronic databases from inception to September 2021 to identify peer-reviewed published English language studies that used FI interventions with adult PEH. A scoping review methodology was used to chart relevant data uniformly. Descriptive statistics and narrative syntheses were used to describe outcomes. Thirty-three quantitative articles related to 29 primary studies were published between 1990 and 2021 and met inclusion criteria. Studies targeted three areas of health behaviour change: decreasing substance use or increasing abstinence rates, preventing or treating infectious diseases or promoting lifestyle/general health goal attainment. A variety of FIs were used (cash/non-cash, escalating/fixed schedule, larger/smaller amounts, some/all behaviours rewarded, certain/uncertain reward) across studies. Twenty-six of the primary studies reported significantly better outcomes for the participants receiving FI compared to controls. There were mixed findings about the efficacy of cash versus non-cash FIs, non-cash FIs versus other interventions and higher versus lower value of incentives. Furthermore, there was limited research about long-term outcomes and impacts. FIs have promise in increasing abstinence from substances, engagement in infectious disease treatment, retention in health services and general lifestyle modifications for PEH. Future research should examine long-term impacts and the contribution of co-interventions and intermediary lifestyle behaviour changes.

Drug checking services for people who use drugs: a systematic review.

BACKGROUND AND AIMS: Drug checking services provide people who use drugs with chemical analysis results of their drug samples while simultaneously monitoring the unregulated drug market. We sought to identify and synthesize literature on the following domains: (a) the influence of drug checking services on the behaviour of people who use drugs; (b) monitoring of drug markets by drug checking services; and (c) outcomes related to models of drug checking services. METHODS: Systematic review. A systematic literature search was conducted in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, PsycINFO, Scopus, Web of Science and Dissertations and Theses Global. Eligible studies were peer-reviewed articles and conference abstracts or grey literature, published in any language since 1990 and including original data on the domains. We assessed risk of bias for quantitative peer-reviewed articles reporting on behaviour or models of drug checking services using National Institutes of Health tools. RESULTS: We screened 2463 titles and abstracts and 156 full texts, with 90 studies meeting inclusion criteria. Most (n = 65, 72.2%) were from Europe and used cross-sectional designs (n = 79, 87.7%). Monitoring of drug markets by drug checking services (n = 63, 70%) was the most reported domain, followed by the influence of drug checking services on behaviour (n = 31, 34.4%), including intent to use, actual use and disposal of the drug, and outcomes related to models of drug checking services (n = 17, 18.9%). The most common outcome measures were detection of unexpected substances (n = 50, 55.6%), expected substances (n = 44, 48.9%), new psychoactive substances (n = 40, 44.4%) and drugs of concern (n = 32, 36.5%) by drug checking services. CONCLUSIONS: Drug checking services appear to influence behavioural intentions and the behaviour of people who use drugs, particularly when results from drug checking services are unexpected or drugs of concern. Monitoring of drug markets by drug checking services is well established in Europe, and increasingly in North America. Concerns about drug contents and negative health consequences facilitate the use of drug checking services; lack of concern; trust in drug sellers; lack of accessibility of drug checking services; and legal and privacy concerns are barriers to use.

Knowledge translation approaches and practices in Indigenous health research: A systematic review.

Knowledge translation (KT) is a critical component of any applied health research. Indigenous Peoples' health research and KT largely continues to be taught, developed, designed, regulated, and conducted in ways that do not prioritize local Indigenous Peoples' ways of sharing knowledges. This review was governed and informed by Indigenous health scholars, Knowledge Guardians, and Elders. Our systematic review focused on answering, what are the promising and wise practices for KT in the Indigenous health research field? Fifty-one documents were included after screening published literature from any country and grey literature from what is now known as Canada. This included contacting 73 government agencies at the federal, territorial, and provincial levels that may have funded Indigenous health research. Only studies that: a) focused on Indigenous Peoples' health and wellness; b) documented knowledge sharing activities and rationale; c) evaluated the knowledge sharing processes or outcomes; and d) printed in English were included and appraised using the Well Living House quality appraisal tool. The analysis was completed using an iterative and narrative synthesis approach. Our systematic review protocol has been published elsewhere. We highlight and summarize the varied aims of Indigenous health research KT, types of KT methodologies and methods used, effectiveness of KT efforts, impacts of KT on Indigenous Peoples' health and wellness, as well as recommendations and lessons learned. Few authors reported using rigorous KT evaluation or disclosed their identity and relationship with the Indigenous communities involved in research (i.e. self-locate). The findings from this review accentuate, reiterate and reinforce that KT is inherent in Indigenous health research processes and content, as a form of knowing and doing. Indigenous health research must include inherent KT processes, if the research is by, for, and/or with Indigenous Peoples.

Social determinants of COVID-19 incidence and outcomes: A rapid review.

Early reports indicate that the social determinants of health are implicated in COVID-19 incidence and outcomes. To inform the ongoing response to the pandemic, we conducted a rapid review of peer-reviewed studies to examine the social determinants of COVID-19. We searched Ovid MEDLINE, Embase, PsycINFO, CINAHL and Cochrane Central Register of Controlled Trials from December 1, 2019 to April 27, 2020. We also searched the bibliographies of included studies, COVID-19 evidence repositories and living evidence maps, and consulted with expert colleagues internationally. We included studies identified through these supplementary sources up to June 25, 2020. We included English-language peer-reviewed quantitative studies that used primary data to describe the social determinants of COVID-19 incidence, clinical presentation, health service use and outcomes in adults with a confirmed or presumptive diagnosis of COVID-19. Two reviewers extracted data and conducted quality assessment, confirmed by a third reviewer. Forty-two studies met inclusion criteria. The strongest evidence was from three large observational studies that found associations between race or ethnicity and socioeconomic deprivation and increased likelihood of COVID-19 incidence and subsequent hospitalization. Limited evidence was available on other key determinants, including occupation, educational attainment, housing status and food security. Assessing associations between sociodemographic factors and COVID-19 was limited by small samples, descriptive study designs, and the timeframe of our search. Systematic reviews of literature published subsequently are required to fully understand the magnitude of any effects and predictive utility of sociodemographic factors related to COVID-19 incidence and outcomes. PROSPERO: CRD4202017813.

Interventions designed to increase the uptake of lung cancer screening and implications for priority populations: a scoping review protocol.

BACKGROUND: When designing any health intervention, it is important to respond to the unequal determinants of health by prioritising the allocation of resources and tailoring interventions based on the disproportionate burden of illness. This approach, called the targeting of priority populations, can prevent a widening of health inequities, particularly those inequities which can be further widened by differences in the uptake of an intervention. The objective of this scoping review is to describe intervention(s) designed to increase the uptake of lung cancer screening, including the health impact on priority populations and to describe knowledge and implementation gaps to inform the design of equitable lung cancer screening. METHODS: We will conduct a scoping review following the methodological framework developed by Arksey and O'Malley. We will conduct comprehensive searches for lung cancer screening promotion interventions in Ovid Medline, Embase, the Cochrane Library, Cumulative Index to Nursing & Allied Health (CINAHL) and Scopus. We will include published English language peer-reviewed and grey literature published between January 2000 and 2020 that describe an intervention designed to increase the uptake of low-dose CT (LDCT) lung cancer screening in the Organization for Economic Cooperation and Development countries. Articles not in English or not describing LDCT will be excluded. Three authors will review retrieved literature in three steps: title, abstract and then full text. Three additional authors will review discrepancies. Authors will extract data from full-text papers into a chart adapted from the Template for Intervention Description and Republication checklist, the Consolidated Standards of Reporting Trials and a Health Equity Impact Assessment tool. Findings will be presented using a narrative synthesis. ETHICS AND DISSEMINATION: The knowledge synthesised will be used to inform the equitable design of lung cancer screening and disseminated through conferences, publications and shared with relevant partners. The study does not require research ethics approval as literature is available online.

COVID-19 Economic Response and Recovery: A Rapid Scoping Review.

This rapid scoping review of existing evidence and research gaps addressed the following question: what research evidence exists and what are the research gaps at global, regional, and national levels on interventions to protect jobs, small- and medium-sized enterprises, and formal/informal sector workers in socioeconomic response to the coronavirus disease 2019 (COVID-19) pandemic? The results are based on 79 publications deemed eligible for inclusion after the screening and prioritizing of 1,658 records. The findings are organized according to the 3 main categories of socioeconomic interventions-protecting jobs, enterprises, and workers-although the 3 are intertwined. Most results were derived from global-level gray literature with recommendations for interventions and implicit links to the sustainable development goals. Based on research gaps uncovered in the review, future implementation science research needs to focus on designing, implementing, evaluating, and scaling: effective evidence-based socioeconomic interventions; equity-focused, redistributive, and transformative interventions; comprehensive packages of complementary interventions; interventions to upend root causes of systemic social inequities; collaborative and participatory approaches; interventions that integrate environmental sustainability; and city-level interventions. Failing to consider the environmental dimensions of economic recovery is shortsighted and will ultimately exacerbate social inequities and poverty and undermine economic stability in the long term.

Pediatric timing of epinephrine doses: A systematic review.

AIM: To evaluate the optimal timing and doses of epinephrine for Infants and children suffering in-hospital or out-of-hospital cardiac arrest. METHODS: We searched Medline, EMBASE, and Cochrane Controlled Register of Trials (CENTRAL) for human randomized clinical trials and observational studies including comparative cohorts. Two investigators reviewed relevance of studies, extracted the data, conducted meta-analyses and assessed the risk of bias using the GRADE and CLARITY frameworks. Authors of the eligible studies were contacted to obtain additional data. Critically important outcomes included return of spontaneous circulation, survival to hospital discharge and survival with good neurological outcome. RESULTS: We identified 7 observational studies suitable for meta-analysis and no randomized clinical trials. The overall certainty of evidence was very low. For the critically important outcomes, the earlier administration of epinephrine was favorable for both in-hospital and out-of-hospital cardiac arrest. Because of a limited number of eligible studies and the presence of severe confounding factors, we could not determine the optimal interval of epinephrine administration. CONCLUSIONS: Earlier administration of the first epinephrine dose could be more favorable in non-shockable pediatric cardiac arrest. The optimal interval for epinephrine administration remains unclear.
