UNASSIGNED: Hypercholesterolemia is a common condition characterized by elevated levels of low-density lipoprotein cholesterol (LDL-C) and increased risk of atherosclerotic cardiovascular disease (ASCVD). Indigenous populations experience disproportionate rates of ASCVD, however, the extent to which hypercholesterolemia contributes to this burden is unknown.
UNASSIGNED: This study aimed to estimate the prevalence of hypercholesterolemia, severe hypercholesterolemia, and familial hypercholesterolemia (FH) in Indigenous populations in Canada, the United States, Australia, and New Zealand.
UNASSIGNED: We searched MEDLINE, EMBASE, Web of Science, Native Health Database, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews for peer-reviewed studies reporting on hypercholesterolemia and elevated LDL-C in Indigenous populations. All diagnostic criteria used to classify hypercholesterolemia were included. Pooled prevalence and 95% CIs were calculated using a random-effects model.
UNASSIGNED: There were no studies reporting the prevalence of FH and one study reporting the prevalence of severe hypercholesterolemia in Indigenous populations. The pooled prevalence of hypercholesterolemia was 28.9% or ∼1 in 3 to 1 in 4 individuals (95% CI: 22.4%-36.4%) and 12.6% (95% CI: 7.7%-19.9%) using an LDL-C cutoff of ≥3.5 mmol/L (135 mg/dL). The pooled prevalence in Indigenous populations in North America was 24.3% (95% CI: 17.1%-33.3%) compared with 40.0% (95% CI: 31.3%-49.3%) in Australia. Meta-regression showed diabetes had a significant effect on prevalence (P = 0.022).
UNASSIGNED: Hypercholesterolemia is prevalent in Indigenous communities and may contribute to the high burden of ASCVD these populations face. There is insufficient research on FH and severe hypercholesterolemia in Indigenous populations worldwide.

OBJECTIVE: The objective of this study was to estimate prevalence of hepatitis C virus (HCV) exposure and infection among Indigenous and tribal populations globally.
METHODS: Systematic review and meta-analysis.
METHODS: We systematically searched bibliographic databases and grey literature (1/01/2000-16/06/2022). Prevalence estimates were synthesised overall, by World Health Organization region and HCV-risk group. For studies with comparator populations, prevalence ratios were estimated and pooled.
RESULTS: Ninety-two studies were included. Globally, among general Indigenous and tribal populations, the median prevalence of HCV antibody (HCV Ab) was 1.3% (interquartile range [IQR]: 0.3-3.8%, I2 = 98.5%) and HCV RNA was 0.4% (IQR: 0-1.3%, I2 = 96.1%). The Western Pacific Region had the highest prevalence (HCV Ab: median: 3.0% [IQR: 0.4-11.9%], HCV RNA: median 5.6% [IQR: 2.0-8.8%]). Prevalence was highest in people who injected drugs (HCV Ab: median: 59.5%, IQR: 51.5-67.6%, I2 = 96.6%; and HCV RNA: median: 29.4%, IQR: 21.8-35.2%, I2 = 97.2%). There was no association between HCV Ab prevalence and Indigenous/tribal status for general populations (prevalence ratio = 0.91; 95% CI: 0.56, 1.49) or key risk groups.
CONCLUSIONS: Indigenous and tribal peoples from the Western Pacific Region and recognised at-risk sub-populations had higher HCV prevalence. HCV prevalence showed no association with Indigenous/tribal status. However, this review was limited by heterogeneity and poor quality of constituent studies, varying definitions of Indigenous/tribal status, regional data gaps, and limited studies on chronic infection (HCV RNA). Comprehensive quality evidence on HCV epidemiology in Indigenous and tribal peoples is needed to tailor preventive and treatment interventions so these populations are not left behind in elimination efforts.

Aboriginal Australians experience disproportionately high rates of mental health problems as the result of European colonisation, and Western evidence-based treatment has been strikingly ineffective in improving the situation. Cultural Therapeutic Ways is a culturally specific healing and wellbeing practice framework developed by the Victorian Aboriginal Child and Community Agency that focuses on culturally based practices, trauma awareness, and self-determination. Despite wide recognition of the importance of these elements in Indigenous healing and wellbeing programs, its measurable empirical impact is currently unclear. This paper summarises findings from a systematic scoping review to ascertain the published knowledge base for Cultural Therapeutic Ways and the gaps in knowledge that can inform future evaluation. Forty-two studies of programs that applied Cultural Therapeutic Ways with Indigenous participants from Australia, Canada, New Zealand, and the United States of America were identified from the literature search. Services based on Cultural Therapeutic Ways contributed to healing and wellbeing because they create safety, strengthen cultural connections, develop empowerment and provide opportunities to release emotion, and increase social and spiritual support. As the review set out to determine the published evidence base for Cultural Therapeutic Ways, other effective approaches may have been overlooked. To develop the evidence base for Cultural Therapeutic Ways, service design must clearly describe target groups, whether the program is delivered by Aboriginal people, the processes of Cultural Therapeutic Ways utilised in service delivery, and how they are blended with Western approaches. Research efforts could also productively be focused on identifying or constructing culturally appropriate outcome measures.

UNASSIGNED: First Nations populations have poorer colorectal cancer (CRC) survival compared to non-First Nations populations. Whilst First Nations populations across the world are distinct, shared experiences of discrimination and oppression contribute to persistent health inequities. CRC screening improves survival, however screening rates in First Nations populations are poorly described. This study seeks to define participation rates in CRC screening in First Nations populations worldwide.
UNASSIGNED: A systematic literature search was conducted of PubMed, Embase, Cochrane Library, CINAHL, MEDLINE, grey literature, national registries and ClinicalTrials.gov. All sources were searched from their inception date to 18 February 2024. Studies were included if they reported CRC screening rates in adult (≥18 years) First Nations populations. We aimed to undertake a meta-analysis if there were sufficient data. Quality of papers were assessed using the Joanna Briggs Institute (JBI) appraisal tool. The study was registered with PROSPERO, CRD42020210181.
UNASSIGNED: The literature search identified 1723 potentially eligible published studies. After review, 57 studies were included, 50 from the United States (US), with the remaining studies from Australia, Aotearoa New Zealand (NZ), Canada, Dominica and Guatemala. Additionally, eleven non-indexed reports from national programs in Australia and NZ were included. There were insufficient data to undertake meta-analysis, therefore a systematic review and narrative synthesis were conducted. CRC screening definitions varied, and included stool-based screening, sigmoidoscopy and colonoscopy. US First Nations screening rates ranged between 4.0 and 79.2%, Australia reported 10.6-35.2%, NZ 18.4-49%, Canada 22.4-53.4%, Guatemala 2.2% and Dominica 4.2%. Fifty-five studies were assessed as moderate or high quality and two as low quality.
UNASSIGNED: Our findings suggested that there is wide variation in CRC screening participation rates across First Nations populations. Screening data are lacking in direct comparator groups and longitudinal outcomes. Disaggregation of screening data are required to better understand and address First Nations CRC outcome inequities.
UNASSIGNED: None.

UNASSIGNED: Violence within families is a complex problem which significantly impacts health and wellbeing. Despite the ubiquitous call for integrated family violence service delivery, integrated approaches vary significantly and challenges to implementation remain. This scoping review explored how integrated approaches to family violence service delivery are conceptualised within international and Aotearoa New Zealand literature.
UNASSIGNED: Following a documented scoping review process identified from literature, dynamic interplay between system agents within integrated family violence service delivery were mapped with the assistance of a complexity theory lens. We analysed characteristics of included studies, agents involved, how they interacted and the methods and mechanisms of integration among them.
UNASSIGNED: Seventy-two published reports were included. The most common interactions occurred between statutory agencies such as police and child protection. While health care service providers were included within 55 studies, their engagement was often peripheral. Qualitative analysis elucidated three broad pathways to service delivery impact underpinned by systems-centred, person-centred, or Indigenous-centred worldviews.
UNASSIGNED: Integrated approaches to family violence service delivery are highly variable. Despite a strong assumption that integration leads to improved safety, health, and wellbeing for care-seekers, most studies did not include evidence of such impact. Consideration of how worldviews characterise service provision provides insight into why integration has proven challenging over time.

BACKGROUND: A major cause of death, coronary artery disease (CAD) often necessitates invasive procedures like coronary bypass grafting (CABG) and percutaneous coronary intervention (PCI). Cardiovascular outcomes vary between indigenous and non-indigenous Australian people; however, comprehensive knowledge of these differences is absent.
METHODS: To compare PCI and CABG results between indigenous and non-indigenous Australians, a systematic review and meta-analysis were carried out. Included were 10 retrospective observational studies that examined mortality, cardiovascular events, comorbidities, and operative success rates. Databases spanning 2014 to 2024 were searched, and research that directly compared Australia\'s indigenous and non-indigenous populations was among the inclusion criteria.
RESULTS: Within 30 days of surgery, indigenous Australians receiving PCI had greater rates of comorbidities and were at higher risk of long-term mortality and MACE. Similarly, there was a greater long-term death rate among indigenous patients following CABG. Cultural safety, socioeconomic factors, and regional factors affecting treatment delays and access to care all affected disparities. For 30-day mortality, the pooled analysis shows an odds ratio of 1.04 (95% CI 0.78, 1.40), indicating no meaningful difference. The total odds ratio for unfavorable occurrences is 1.07 (95% CI 0.86, 1.33), meaning there is no statistically significant difference between Indigenous groups and those that are not.
CONCLUSIONS: Indigenous Australians continue to have worse cardiovascular outcomes after PCI and CABG procedures, even with similar procedural success rates. To ensure equitable cardiovascular outcomes for indigenous groups, targeted therapies targeting underlying risk factors, increased access to culturally appropriate care, and decreased obstacles to healthcare access are critical.

OBJECTIVE: To synthesise international literature to identify mechanisms that maintain racism in nursing and understand the factors that contribute to designing and implementing anti-racist praxis to inform nursing in Aotearoa New Zealand.
METHODS: An integrative literature review was undertaken, integrating Indigenous Kaupapa Māori methodologies to ensure a cultural and philosophical lens.
METHODS: Peer-reviewed literature published, between January 2011 and July 2023 were sourced. Of 1296 articles, 16 met the inclusion criteria and 4 were identified via citation chaining. In total, 20 articles were included. The Johns Hopkins Research Evidence Tool was applied, findings extracted, and thematic analysis completed utilising Indigenous Kaupapa Māori principles.
METHODS: Databases, including CINAHL, Scopus, PubMed and Aus/NZ Reference Centre, were searched in July 2023.
RESULTS: Two key themes were identified: (1) colonial active resistance to change; and (2) transformational, visionary, and proactive nursing.
CONCLUSIONS: Nurses are well-positioned to confront the structures that maintain racism in health and education systems but are often actors in maintaining status quo. Anti-racist praxis can be a mechanism for nurses to reimagine, redefine and transform nursing care, leadership, and nursing education to begin to eradicate racism.
UNASSIGNED: This integrative review adhered to the 2020 Preferred Reporting for Systematic Reviews and Meta-Analyses (PRISMA) method.
UNASSIGNED: No patient or public contribution.
UNASSIGNED: Racism remains prevalent in nursing and the healthcare system. It is necessary to implement anti-racist praxis and policies that resist, deconstruct, and dismantle power and racism while validating Indigenous values, beliefs and practices. This is vital to deliver equitable health care.
CONCLUSIONS: This integrative review presents lived realities and knowledge of Indigenous and racially minoritised nurses and scholars, alongside nursing allies to inform anti-racist praxis. This evidence signifies that it is time to walk the walk to challenge the colonising systems and processes that hold racism in place.

UNASSIGNED: The role of alcohol varies considerably among Indigenous Peoples and is the backdrop of persistent stereotypes despite decades of research. This paper provides an updated narrative review on the alcohol literature among Indigenous communities, highlighting recent studies published since 2017.
UNASSIGNED: We examined published literature involving alcohol use rates, including abstinence; risk and protective factors; treatment; and recovery, as well as future directions for alcohol prevention and intervention efforts with Indigenous communities.
UNASSIGNED: Evidence-based alcohol use prevention, intervention, and recovery strategies with Indigenous communities are outlined. Recommendations are provided for researchers, health providers, and public policy advocates to address and better understand alcohol use, treatment, prevention, and recovery among Indigenous Peoples. Specific recommendations include using community-based participatory research strategies and harm reduction approaches to prevent and treat alcohol use problems with Indigenous communities. Future research is needed to elucidate mechanisms of resilience and recovery from Alcohol Use Disorder and possible shifts in perceptions of alcohol use for Indigenous Peoples.

The overincarceration of Indigenous peoples and its impacts on individual and community health is a growing concern across Canada and the United States. Federally run Healing Lodges in Canada are an example of support services for incarcerated and previously incarcerated Indigenous peoples to reintegrate into community and support their healing journey. However, there is a need to synthesise research which investigates these programmes. We report a protocol for a scoping review that is guided by the following research question: What is known about culturally informed programmes and services available to incarcerated and previously incarcerated Indigenous peoples in Canada and the US? This scoping review will follow guidelines published by the Joanna Briggs Institute and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. This review will only identify programmes that are guided by Indigenous ways of being and knowing in order to best serve Indigenous communities and our community partners. The results of this review will support the development of programmes that are necessary for understanding and addressing the diverse needs of incarcerated and previously incarcerated Indigenous peoples.

The purpose of this scoping review was to determine the extent to which accessibility and acceptability of federal food assistance programs in the United States have been evaluated among indigenous peoples and to summarize what is currently known. Twelve publications were found that examine aspects of accessibility or acceptability by indigenous peoples of 1 or more federal food assistance programs, including the supplemental nutrition assistance program (SNAP) and/or the Food Distribution Program on Indian Reservations (n = 8), the Special Supplemental Nutrition Program for Women, infants, and children (WIC) (n = 3), and the national school lunch program (n = 1). No publications were found to include the commodity supplemental food program or the child and adult care food program. Publications ranged in time from 1990-2023, and all reported on findings from rural populations, whereas 3 also included urban settings. Program accessibility varied by program type and geographic location. Road conditions, transportation access, telephone and internet connectivity, and an overall number of food stores were identified as key access barriers to SNAP and WIC benefit redemption in rural areas. Program acceptability was attributed to factors such as being tribally administered, providing culturally sensitive services, and offering foods of cultural significance. For these reasons, Food Distribution Program on Indian Reservations and WIC were more frequently described as acceptable compared to SNAP and national school lunch programs. However, SNAP was occasionally described as more acceptable than other assistance programs because it allows participants autonomy to decide which foods to purchase and when. Overall, little attention has been paid to the accessibility and acceptability of federal food assistance programs among indigenous peoples in the United States. More research is needed to understand and improve the participation experiences and health trajectories of these priority populations.
