Oral health in a First Nations and a non-Aboriginal population in Manitoba

The Impact of Rheumatoid Arthritis on First Nations and How We Can Work With Communities to Prevent It

Rheumatoid arthritis (RA) is prevalent in many Indigenous North American First Nations (FN) and tends to be seropositive, familial, and disabling, as well as associated with highly unfavorable outcomes such as early mortality. The risk of developing RA is based on a perfect storm of gene-environment interactions underpinning this risk. The gene-environment interactions include a high frequency of shared epitope encoding HLA alleles, particularly HLA-DRB1*1402, in the background population, and prevalent predisposing environmental factors such as smoking and periodontal disease. Together, these provide a compelling rationale for an RA prevention agenda in FN communities. Our research team has worked in partnership with several FN communities to prospectively follow the first-degree relatives of FN patients with RA, with the aim of better understanding the preclinical stages of RA in this population. We have focused on specific features of the anticitrullinated protein antibodies (ACPA) and other proteomic biomarkers as predictors of future development of RA. These studies have now led us to consider interventions having a favorable risk-benefit ratio if applied at a stage prior to a hypothetical "point of no return," when the autoimmunity potentially becomes irreversible. Based on a supportive mouse model and available human studies of curcumin, omega-3, and vitamin D supplements, we are undertaking studies where we screen communities using dried blood spot technology adapted for the detection of ACPA, and then enrolling ACPA-positive individuals in studies that use a combination of these supplements. These studies are guided by shared decision-making principles.

Disparities in rheumatoid arthritis outcomes for North American Indigenous populations

Advances in rheumatoid arthritis (RA) management have significantly improved clinical outcomes of this disease; however, some Indigenous North Americans (INA) with RA have not achieved the high rates of treatment success observed in other populations. We review factors contributing to poor long-term outcomes for INA with RA. We conducted a narrative review of studies evaluating RA in INA supplemented with regional administrative health and clinical cohort data on clinical outcomes and health care utilisation. We discuss factors related to conducting research in INA populations including studies of RA prevention. NA with RA have a high burden of genetic and environmental predisposing risk factors that may impact disease phenotype, delayed or limited access to rheumatology care and advanced therapy. These factors may contribute to the observed increased rates of persistent synovitis, premature end-stage joint damage and mortality. Novel models of care delivery that are culturally sensitive and address challenges associated with providing speciality care to patients residing in remote communities with limited accessibility are needed. Progress in establishing respectful research partnerships with INA communities has created a foundation for ongoing initiatives to address care gaps including those aimed at RA prevention. This review highlights some of the challenges of diagnosing, treating, and ultimately perhaps preventing, RA in INA populations.

Physical pain among Indigenous Peoples in Canada: a scoping review

PURPOSE

Pain is a multifaceted experience shaped by various factors including context of pain, previous life events, and ongoing ethnocultural circumstances. Moreover, the definition of pain is inconsistent across cultures. Western medicine views physical pain (e.g., associated with a bone fracture) and nonphysical mental pain (e.g., depression) as two distinct conditions. Indigenous perspectives are often more wholistic, encompassing mental, spiritual, emotional, and physical hurt. The subjective nature of pain invites ample opportunity for discrimination in both its assessment and management. As such, it is important to consider Indigenous perspectives of pain in research and clinical practice. To investigate which aspects of Indigenous pain knowledge are currently considered by Western research, we conducted a scoping review of the literature on pain in Indigenous Peoples of Canada.

SOURCE

In June 2021, we searched nine databases and downloaded 8,220 papers after removal of duplicates. Two independent reviewers screened abstracts and full-text articles.

PRINCIPLE FINDINGS

Seventy-seven papers were included in the analysis. Using grounded theory, five themes emerged: pain measures/scales (n = 7), interventions (n = 13), pharmaceuticals (n = 17), pain expression/experiences (n = 45), and pain conditions (n = 70).

CONCLUSION

This scoping review shows that there is a paucity of research on pain measurement in Indigenous Peoples of Canada. This finding is concerning in light of numerous studies reporting that Indigenous Peoples experience their pain as ignored, minimized, or disbelieved. Furthermore, a clear disconnect emerged between pain expression in Indigenous Peoples and assessment in medical professionals. We hope that this scoping review will serve to translate current knowledge to other non-Indigenous academics and to initiate meaningful collaboration with Indigenous partners. Future research led by Indigenous academics and community partners is critically needed to better address pain needs in Canada.

Key Challenges for Indigenous Peoples of Canada in terms of Oral Health Provision and Utilization: A Scoping Review

Background

The oral health of Indigenous peoples in Canada is lacking compared with their non-Indigenous counterparts. This scoping assessment aimed to investigate the obstacles of providing and using oral healthcare among Indigenous peoples in Canada.

Methods

The scoping review took place between December 15, 2021 and January 10, 2022. Five key databases were examined: PubMed, Scopus, ISI Web of Science, Embase, and PROQUEST. The data were analyzed using NVIVO software to facilitate understanding of the major themes, subthemes, and codes provided.

Results

Seven major themes and eighteen subthemes were identified as impacting the oral health provision and utilization of Indigenous peoples in Canada. The major themes are individual characteristics, affordability, availability, accessibility, accommodation, acceptability, and public or government policy. Thus, to improve the oral health of the Indigenous peoples in Canada, an integrated approach is required to address these obstacles.

Conclusions

To address the oral health disparities among Indigenous peoples in Canada, policymakers should adopt an integrated approach.

Access to oral care is a human rights issue: a community action report from the Downtown Eastside of Vancouver, Canada

To offer a critical reflection on an impoverished neighborhood in Vancouver, Canada, and their access to oral health care. A review of how a lack of publicly funded oral health care affects the most vulnerable, uninsured, and underserved citizens is performed. Personal and professional accounts on how entrepreneurial innovations of not-for-profit organizations can help to close the gap in access to oral health care are offered using the Vancouver Area Network of drug users (VANDU) and the PHS Community Services Society as case studies in British Columbia. Despite the efforts put forward by not-for-profit organizations such as the VANDU and the PHS Community Services Society, a national oral health care plan is warranted though still not a political imperative. Underserved citizens have a right to oral health care that is compassionate, collaborative, accessible, and affordable.

Predictors of self-rated oral health in Canadian Indigenous adults

OBJECTIVES

The purpose of this study was to: (1) compare oral health indicators between Indigenous adults and the general population and (2) examine the predictors of poor self-rated oral health in the Indigenous population.

METHODS

Data from the 2017-2018 cycle of the Canadian Community Health Survey was used and included 943 Indigenous and 20,011 non-Indigenous adults. Independent variables included demographic information, lifestyle behaviours, dental concerns and care utilization, and transportation access. The dependent variable was self-rated oral health. A logistic regression was performed to determine predictors of poor self-rated oral health.

RESULTS

More than half of the Indigenous sample were aged between 35 and 64 years (57.3%); 57.8% were female. Compared to the general population, the Indigenous group were significantly more likely to have no partner, have less post-secondary education, and have an income of less than $40,000. Almost a fifth of the Indigenous sample self-rated their oral health as poor (18.5%) compared to 11.5% in the general population. Indigenous participants reported significantly poorer general health, had poorer oral care practices, and lifestyle behaviours than the general population (all p < .001). Indigenous adults having poor self-rated oral health was predicted by poorer general health, being a smoker, male, bleeding gums, persistent pain, feeling uncomfortable eating food, avoiding foods, and not seeking regular dental care.

CONCLUSIONS

There are many predictors of poor self-rated oral health, many of which are preventable. Providing culturally adapted oral health care may improve the likelihood of Indigeneous adults visiting the dentist for preventative care.

Oral Health in Rheumatoid Arthritis: Listening to Patients

INTRODUCTION

Rates of periodontal disease and tooth loss are increased in individuals with rheumatoid arthritis (RA). Understanding factors that contribute to the increased burden of periodontal disease in RA is critical to improving oral health and arthritis outcomes.

OBJECTIVES

To determine the perceptions held by people with RA relating to their oral health, to identify patient-centered priorities for oral health research, and to inform optimal strategies for delivering oral health knowledge.

METHODS

Semistructured interviews were conducted with patients with RA. Recorded interview transcripts were iteratively reviewed to reveal surface and latent meaning and to code for themes. Constructs were considered saturated when no new themes were identified in subsequent interviews. We report themes with representative quotes.

RESULTS

Interviews were conducted with 11 individuals with RA (10 women [91%]; mean age, 68 y), all of whom were taking RA medication. Interviews averaged 19 min (range, 8 to 31 min) and were mostly conducted face-to-face. Three overall themes were identified: 1) knowledge about arthritis and oral health links; 2) oral health care in RA is complicated, both in personal hygiene practices and in professional oral care; and 3) poor oral health is a source of shame. Participants preferred to receive oral health education from their rheumatologists or dentists.

CONCLUSIONS

People with RA have unique oral health perceptions and experience significant challenges with oral health care due to their arthritis. Adapting oral hygiene recommendations and professional oral care delivery to the needs of those with arthritis are patient priorities and are required to improve satisfaction regarding their oral health.

KNOWLEDGE TRANSLATION STATEMENT

Patients living with long-standing rheumatoid arthritis described poor oral health-related quality of life and multiple challenges with maintaining optimal oral health. Study findings indicate a need for educational materials addressing oral health maintenance for patients with rheumatic diseases and their providers.

Prevalence and Factors Associated with Visiting the Dentist Only for Emergency Care Among Indigenous People in Ontario

Ontario has the largest Indigenous population in Canada. This study aims to examine the prevalence and factors associated with poor dental care use amongst the Indigenous in Ontario. Data from the 2014 cycle of the Canadian Community Health Survey was used. The main outcome was defined as visiting the dentist only for emergency care. Stepwise multivariable logistic regression was performed to assess the association between socio-demographic, socio-economic, and the health related factors and emergency dental care use. 28% of the participants reported visiting the dentist only for emergencies. First Nations people were at increased odds of having poor dental care (OR 2.01, CI 1.12-3.95). Additionally, being male, a smoker, having fair/poor health and lacking dental insurance puts the Indigenous Ontarians at increased odds of having the outcome. Improvements to the current social benefit programs could help better cater to the needs of this population.

Innovating for Transformation in First Nations Health Using Community-Based Participatory Research

Community-based participatory research (CBPR) provides the opportunity to engage communities for sustainable change. We share a journey to transformation in our work with eight Manitoba First Nations seeking to improve the health of their communities and discuss lessons learned. The study used community-based participatory research approach for the conceptualization of the study, data collection, analysis, and knowledge translation. It was accomplished through a variety of methods, including qualitative interviews, administrative health data analyses, surveys, and case studies. Research relationships built on strong ethics and protocols to enhance mutual commitment to support community-driven transformation. Collaborative and respectful relationships are platforms for defining and strengthening community health care priorities. We further discuss how partnerships were forged to own and sustain innovations. This article contributes a blueprint for respectful CBPR. The outcome is a community-owned, widely recognized process that is sustainable while fulfilling researcher and funding obligations.

Pathogenesis and prevention of rheumatic disease: focus on preclinical RA and SLE

Established and emerging data demonstrate that a 'preclinical' period of disease precedes the onset of clinical rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), as well as other autoimmune rheumatic diseases (ARDs).This preclinical stage of development of disease is characterized by abnormalities in disease-related biomarkers before the onset of the clinically apparent signs and symptoms. Numerous genetic and environmental risk factors for ARDs have also been identified, and many of these factors are likely to act before the clinical appearance of tissue injury to initiate and/or propagate autoimmunity and autoimmune disease. Thus, biomarkers representative of these autoimmune processes could potentially be used in conjunction with other clinical parameters during the preclinical period of ARDs to predict the future development of clinically apparent disease. This Review focuses on the preclinical stages of RA and SLE, as our current understanding of these diseases can be used to present an overall model of the development of ARDs that might ultimately be used to develop screening programmes and preventive strategies. Important considerations for the future development of such approaches, in particular, the issues that require additional research and how they might be addressed, are also discussed.
