Access to Primary Health Care Services for Youth Experiencing Homelessness: “You shouldn’t need a health card to be healthy.”

On any given night, thousands of Canadian youth face homelessness in either absolute (living on the street) or relative (couch surfing, staying in emergency shelters) terms.  This study explores influences primary health care access among youth experiencing homelessness in a large Canadian urban centre.  Using a qualitative research design and convenience sampling, 8 youth participated in in-depth individual interviews and 4 clinicians with expertise in working with youth in primary care settings participated in a facilitated solutions-focused dialogue based on findings from the youth interviews.  Data collection occurred from January to November 2016.  Main findings included: (1) Youth experiencing homelessness feel powerless when interacting with health care providers, (2) Health care systems exist as rule-based bureaucracies and (3) Homeless youth are in survival mode when it comes to their health.  The authors offer recommendations to promote more equitable access to primary health care services for homeless youth

"Me, I'm Living It": The Primary Health Care Experiences of Women who use Drugs in Vancouver’s Downtown Eastside: Summary of Findings from the VANDU Women's Clinic Action Research for Empowerment Study

First paragraph: Preventing and reducing the harmful consequences of drug use has been identified as a key priority in Canada at all levels of government. Initiatives to reduce barriers to care for marginalized women who use drugs are currently underway. However, despite the significant national and international attention paid to the health and social conditions of women in Vancouver's Downtown Eastside (DTES), women who use drugs in this community report persistent health inequities and barriers to accessing a wide range of services, including primary health care, harm reduction services, mental health care, and addictions treatment. These inequities and barriers to care result from a complex interplay of social, political and economic factors. In order to provide effective, empowering, compassionate, and respectful care for women who use drugs it is crucial to understand how these factors influence health and well-being

Self-reported oral health among a community sample of people experiencing social and health inequities: Cross-sectional findings from a study to enhance equity in primary healthcare settings

Objective: To describe the self-reported oral health issues among a community sample of primary care clients experiencing socioeconomic disadvantages. Methods: As part of a larger mixed-methods, multiple case study evaluating an equity-oriented primary healthcare intervention, we examined the oral health of a sample of 567 people receiving care at four clinics that serve marginalised populations in two Canadian provinces. Data collected included self-rated oral health and experiences accessing and receiving healthcare, standard self-report measures of health and quality of life, and sociodemographic information. Results: The prevalence of self-rated poor oral health was high, with almost half (46.3%) of the participants reporting poor or fair oral health. Significant relationships were observed between poor oral health and vulnerabilities related to mental health, trauma and housing instability. Our findings suggest that the oral health of some Canadian populations may be dramatically worse than what is reported in existing population health surveys. Conclusions: Our findings reinforce the importance of addressing oral health as part of health equity strategies. The health and oral health issues experienced by this client cohort highlight the need for interdisciplinary, team-based care that can address the intersections among people\u27s health status, oral health and social issues

Through An Equity Lens: Illuminating The Relationships Among Social Inequities, Stigma And Discrimination, And Patient Experiences of Emergency Health Care

People who experience the greatest social inequities often have poor experiences in emergency departments (EDs) so that they are deterred from seeking care, leave without care complete, receive inadequate care, and/or return repeatedly for unre- solved problems. However, efforts to measure and monitor experiences of care rarely capture the experiences of people facing the greatest inequities, experiences of discrimination, or relationships among these variables. This analysis examined how patients’ experiences, including self-reported ratings of care, experiences of discrimination, and repeat visits vary with social and economic circumstances. Every consecutive person presenting to three diverse EDs was invited if/when they were able to consent; 2424 provided demographic and contact information; and 1692 (70%) completed the survey. Latent class analysis (LCA) using sociodemographic variables: age, gender, financial strain, employment, housing stability, English as first language, born in Canada, and Indigenous identity, indicated a six-class solution. Classes differed significantly on having regular access to primary care, reasons for the visit, and acuity. Classes also differed on self-reported discrimination every day and during their ED visit, ratings of ED care, and number of ED visits within the past six months. ED care can be improved through attention to how intersecting forms of structural disadvantage and inequities affect patient experiences

Residual active granzyme B in cathepsin C–null lymphocytes is sufficient for perforin-dependent target cell apoptosis

Cathepsin C activates serine proteases expressed in hematopoietic cells by cleaving an N-terminal dipeptide from the proenzyme upon granule packaging. The lymphocytes of cathepsin C–null mice are therefore proposed to totally lack granzyme B activity and perforin-dependent cytotoxicity. Surprisingly, we show, using live cell microscopy and other methodologies, that cells targeted by allogenic CD8+ cytotoxic T lymphocyte (CTL) raised in cathepsin C–null mice die through perforin-dependent apoptosis indistinguishable from that induced by wild-type CTL. The cathepsin C–null CTL expressed reduced but still appreciable granzyme B activity, but minimal granzyme A activity. Also, in contrast to mice with inactivation of both their granzyme A/B genes, cathepsin C deficiency did not confer susceptibility to ectromelia virus infection in vivo. Overall, our results indicate that although cathepsin C clearly generates the majority of granzyme B activity, some is still generated in its absence, pointing to alternative mechanisms for granzyme B processing and activation. Cathepsin C deficiency also results in considerably milder immune deficiency than perforin or granzyme A/B deficiency

The Efficacy of a Health Promotion Intervention for Indigenous Women: Reclaiming Our Spirits

Indigenous women globally are subjected to high rates of multiple forms of violence, including intimate partner violence (IPV), yet there is often a mismatch between available services and Indigenous women’s needs and there are few evidence-based interventions specifically designed for this group. Building on an IPV-specific intervention (Intervention for Health Enhancement After Leaving [iHEAL]), “Reclaiming Our Spirits” (ROS) is a health promotion intervention developed to address this gap. Offered over 6 to 8 months in a partnership between nurses and Indigenous Elders, nurses worked individually with women focusing on six areas for health promotion and integrated health-related workshops within weekly Circles led by an Indigenous Elder. The efficacy of ROS in improving women’s quality of life and health was examined in a community sample of 152 Indigenous women living in highly marginalizing conditions in two Canadian cities. Participants completed standard self-report measures of primary (quality of life, trauma symptoms) and secondary outcomes (depressive symptoms, social support, mastery, personal agency, interpersonal agency, chronic pain disability) at three points: preintervention (T1), postintervention (T2), and 6 months later (T3). In an intention-to-treat (ITT) analysis, Generalized Estimating Equations (GEE) were used to examine hypothesized changes in outcomes over time. As hypothesized, women’s quality of life and trauma symptoms improved significantly pre- to postintervention and these changes were maintained 6 months later. Similar patterns of improvement were noted for five of six secondary outcomes, although improvements in interpersonal agency were not maintained at T3. Chronic pain disability did not change over time. Within a context of extreme poverty, structural violence, and high levels of trauma and substance use, some women enrolled but were unable to participate. Despite the challenging circumstances in the women’s lives, these findings suggest that this intervention has promise and can be effectively tailored to the specific needs of Indigenous women

Reclaiming our spirits: Development and pilot testing of a health promotion intervention for indigenous women who have experienced intimate partner violence

Indigenous women are subjected to high rates of multiple forms of violence, including intimate partner violence (IPV), in the context of ongoing colonization and neo-colonization. Health promotion interventions for women who experience violence have not been tailored specifically for Indigenous women. Reclaiming Our Spirits (ROS) is a health promotion intervention designed for Indigenous women living in an urban context in Canada. In this paper, we describe the development of the intervention, results of a pilot study, and the revised subsequent intervention. Building on a theory-based health promotion intervention (iHEAL) showing promising results in feasibility studies, ROS was developed using a series of related approaches including (a) guidance from Indigenous women with research expertise specific to IPV and Indigenous women’s experiences; (b) articulation of an Indigenous lens, including using Cree (one of the largest Indigenous language groups in North America) concepts to identify key aspects; and (c) interviews with Elders (n10) living in the study setting. Offered over 6-8 months, ROS consists of a Circle, led by an Indigenous Elder, and 1:1 visits with a Registered Nurse, focused on six areas for health promotion derived from previous research. Pilot testing with Indigenous women (n21) produced signs of improvement in most measures of health from pre- to post-intervention. Women found the pilot intervention acceptable and helpful but also offered valuable suggestions for improvement. A revised intervention, with greater structure within the Circle and nurses with stronger knowledge of Indigenous women’s experience and community health, is currently undergoing testing

The Functional Basis for Hemophagocytic Lymphohistiocytosis in a Patient with Co-inherited Missense Mutations in the Perforin (PFN1) Gene

About 30% of cases of the autosomal recessive immunodeficiency disorder hemophagocytic lymphohistiocytosis are believed to be caused by inactivating mutations of the perforin gene. We expressed perforin in rat basophil leukemia cells to define the basis of perforin dysfunction associated with two mutations, R225W and G429E, inherited by a compound heterozygote patient. Whereas RBL cells expressing wild-type perforin (67 kD) efficiently killed Jurkat target cells to which they were conjugated, the substitution to tryptophan at position 225 resulted in expression of a truncated (∼45 kD) form of the protein, complete loss of cytotoxicity, and failure to traffic to rat basophil leukemia secretory granules. By contrast, G429E perforin was correctly processed, stored, and released, but the rat basophil leukemia cells possessed reduced cytotoxicity. The defective function of G429E perforin mapped downstream of exocytosis and was due to its reduced ability to bind lipid membranes in a calcium-dependent manner. This study elucidates the cellular basis for perforin dysfunctions in hemophagocytic lymphohistiocytosis and provides the means for studying structure–function relationships for lymphocyte perforin
