Healthcare providers (HCPs) play a central role in the provision of prevention and care services for people with sexually transmitted infections (STIs), including HIV/AIDS. However, the degree of readiness for this role through appropriate training and experience is not clear. In the case of both the urban and rural areas of the state of Karnataka, India, primary and secondary healthcare is provided by practitioners who can be categorised into three major groups: qualified allopathic physicians, qualified non-allopathic doctors (homeopathic and Ayurvedic) and registered medical practitioners. In 2002, the India-Canada Collaborative HIV/AIDS Project conducted a study in an urban area and a rural district of the state of Karnataka, collecting information from 998 care providers regarding attitudes, knowledge and practices related to STI care and HIV/AIDS care in particular. This paper analyses and compares the three different types of HCPs with respect to these parameters and discusses implications for STI/HIV/AIDS prevention and care programs. [ABSTRACT FROM AUTHOR]

- Abstract
Indigenous governance of health care has increasingly been advocated among Indigenous peoples in many countries. However, there is limited research that has empirically examined its benefits. In 2020/21, we conducted a survey of 2113 Indigenous Wayuu individuals in Colombia who received services from the Indigenous Wayuu led health care insurance organization Anas Wayuu and its network of service providers, and Wayuu individuals who received services from non-Indigenous health insurance organizations. We compared their health care utilization and perception of quality of care. A main finding of the study was that Anas Wayuu enrollees were more than twice as likely to access health care than enrollees from non-Indigenous health insurance organizations, even when controlling for the demographic and health characteristics. The study provided compelling evidence suggesting that Anas Wayuu, being an Indigenous led health organization improves access to, and quality of care, among Indigenous health service recipients., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Abstract: Negative attitudes/beliefs surrounding osteoarthritis, pain, and activity contribute to reduced physical activity in people with knee osteoarthritis (KOA). These attitudes/beliefs are assessed using self-report questionnaires, relying on information one is consciously aware of and willing to disclose. Automatic (ie, implicit) assessment of attitudes does not rely on conscious reflection and may identify features unique from self-report. We developed an implicit association test that explored associations between images of a person moving/twisting their knee (activity) or sitting/standing (rest), and perceived threat (safe vs dangerous). We hypothesised that people with KOA would have greater implicit threat-activity associations (vs pain-free and non-knee pain controls), with implicit attitudes only weakly correlating with self-reported measures (pain knowledge, osteoarthritis/pain/activity beliefs, fear of movement). Participants (n = 558) completed an online survey: 223 had painful KOA (n = 157 female, 64.5 ± 8.9 years); 207 were pain free (n = 157 female, 49.3 ± 15.3 years); and 99 had non-KOA lower limb pain (n = 74 female, 47.5 ± 15.04 years). An implicit association between "danger" and "activity" was present in those with and without limb pain (KOA: 0.36, 95% CI 0.28-0.44; pain free: 0.13, 95% CI 0.04-0.22; non-KOA lower limb pain 0.11, 95% CI -0.03 to 0.24) but was significantly greater in the KOA group than in the pain free ( P < 0.001) and non-KOA lower limb pain ( P = 0.004) groups. Correlations between implicit and self-reported measures were nonsignificant or weak (rho = -0.29 to 0.19, P < 0.001 to P = 0.767). People with painful KOA hold heightened implicit threat-activity associations, capturing information unique to that from self-report questionnaires. Evaluating links between implicit threat-activity associations and real-world behaviour, including physical activity levels, is warranted., (Copyright © 2024 International Association for the Study of Pain.)

- Abstract
The objective of the study was to assess the consistency between self-reported demographic characteristics, health conditions, and healthcare use, and administrative healthcare records, in a sample of enrollees of an Indigenous health organization in Colombia. We conducted a phone survey of a random sample of 2113 enrollees September-2020/February-2021. Administrative health records were obtained for the sample. Using ICD-10 diagnostic codes, we identified individuals who had healthcare visits for diabetes, hypertension, and/or pregnancy. Using unique identifiers, we linked their survey data to the administrative dataset. Agreement percentages and Cohen's Kappa coefficients were calculated. Logistic regressions were performed for each health condition/state. Results showed high degree of agreement between data sources for sex and age, similar rates for diabetes and hypertension, 10% variation for pregnancy. Kappa statistics were in the moderate range. Age was significantly associated with agreement between data sources. Sex, language, and self-rated health were significant for diabetes. This is the first study with data from an Indigenous population assessing the consistency between self-reported data and administrative health records. Survey and administrative data produced similar results, suggesting that Anas Wauu can be confident in using their data for planning and research purposes, as part of the movement toward data sovereignty., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
We describe a two-step process for the synthesis of substituted bicyclo[1.1.0]butanes. A photo-Hunsdiecker reaction generates iodo-bicyclo[1.1.1]pentanes under metal-free conditions at room temperature. These intermediates react with nitrogen and sulfur nucleophiles to afford substituted bicyclo[1.1.0]butane products.

- Abstract
A series of dihydropyridinone (DHP) compounds was prepared and evaluated for MGAT2 activity. The efforts led to the identification of novel tetrazolones with potent MGAT2 inhibitory activity and favorable in vitro profiles. Further tests of select analogues in mouse models revealed significant reduction in food intake and body weight. Subsequent studies in MGAT2 knockout mice with the lead candidate 12 (BMS-986172) showed on-target- and mechanism-based pharmacology. Moreover, its favorable pharmacokinetic (PK) profile and the lack of species variability in the glucuronidation potential resulted in a greater confidence level in the projection of a low dose for achieving targeted efficacious exposures in humans. Consistent with these projections, PK data from a phase 1 trial confirmed that targeted efficacious exposures could be achieved at a low dose in humans, which supported compound 12 as our second and potentially superior development candidate for the treatment of various metabolic disorders.

- Abstract
Inhibition of monoacylglycerol transferase 2 (MGAT2) has recently emerged as a potential therapeutic strategy for the treatment of metabolic diseases such as obesity, diabetes and non-alcoholic steatohepatitis (NASH). Metabolism studies with our clinical lead (1) suggested variability in in vitro glucuronidation rates in liver microsomes across species, which made projection of human doses challenging. In addition, the observation of deconjugation of the C3-C4 double bond in the dihydropyridinone ring of 1 in solution had the potential to complicate its clinical development. This report describes our lead optimization efforts in a novel pyridinone series, exemplified by compound 33, which successfully addressed both of these potential issues., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

- Abstract
Introduction: Rising use of methamphetamine is causing significant public health concern in Canada. The biological and behavioural effects of methamphetamine range from wakefulness, vigour and euphoria to adverse physical health outcomes like myocardial infarction, haemorrhagic stroke, arrhythmia and seizure. It can also cause severe psychological complications such as psychosis. National survey data point to increasing rates of methamphetamine use, as well as increasing ease of access and serious methamphetamine-related harms. There is an urgent need for evidence to address knowledge gaps, provide direction to harm reduction and treatment efforts and inform health and social policies for people using methamphetamine. This protocol describes a study that aims to address this need for evidence., Methods: The study will use linked, whole population, de-identified administrative data from the Manitoba Population Research Data Repository. The cohort will include individuals in the city of Winnipeg, Manitoba, who came into contact with the health system for reasons related to methamphetamine use from 2013 to 2021 and a comparison group matched on age, sex and geography. We will describe the cohort's sociodemographic characteristics, calculate incidence and prevalence of mental disorders associated with methamphetamine use and examine rates of health and social service use. We will evaluate the use of olanzapine pharmacotherapy in reducing adverse emergency department outcomes. In partnership with Indigenous co-investigators, outcomes will be stratified by First Nations and Métis identity., Ethics and Dissemination: The study was approved by the University of Manitoba Health Research Ethics Board, and access datasets have been granted by all data providers. We also received approval from the First Nations Health and Social Secretariat of Manitoba's Health Information Research Governance Committee and the Manitoba Métis Federation. Dissemination will be guided by an 'Evidence 2 Action' group of public rightsholders, service providers and knowledge users who will ensure that the analyses address the critical issues., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

- Abstract
Africa is endowed with a profoundly rich and diverse system of plants and other bio-resources out of which, by traditional medicine practice, the people have satisfied their healthcare needs right from antiquity. In contemporary times, it has become necessary to modernize this traditional medical care system via scientific studies. Validation of the efficacy of health-enhancement products and drugs from plants and other bio-resources is predicated on diligent and intensive research accompanied by rigorous and conclusive clinical trials. Africa has eminently qualified human resources but due to the finance-intensive nature of medical research, individual African states on their own cannot fund the level of research desired for dealing with such serious issues as the COVID-19 pandemic. A collaboration among African states guided by a Mutual Pan-African support paradigm (MPASP) is a unique strategy for achieving success in any such a high-impact global project as the use of traditional medicine against COVID-19 and emerging pandemics; and this is hereby advocated., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2021 The Authors.

- Abstract
Objective: Mood and anxiety disorders (MADs) are common conditions with multiple aetiologies. Exposure to antibiotics has been proposed as a possible risk factor in animal studies. We aimed to assess maternal antibiotic use in pregnancy and child antibiotic use in the first three years of life, collectively called early life, as potential risk factors for subsequent development of MADs during childhood and adolescence., Methods: A population-based retrospective cohort study was conducted including 221,139 children born in Manitoba, Canada between 1996 and 2012. Exposure was defined as having filled one or more antibiotic prescriptions during early life. Children were followed until the earliest MADs diagnoses, 19th birthday, migration, death, or end of the study period. We computed crude and adjusted hazard ratios (aHRs) with corresponding 95% confidence intervals (CIs) using Cox proportional hazard regression., Results: Children born to mothers who received one or more antibiotic courses in pregnancy had significantly higher rates of MADs compared with non-exposed children (aHR 1.08, 95% CI 1.03,1.13). Overall antibiotic exposure during the first three years of life was not significantly associated with MADs (aHR 1.00, 95% CI 0.94,1.07). A significantly increased risk of MADs was observed after postnatal exposure to tetracyclines, aminoglycosides, quinolones (33%) or sulfonamides and trimethoprim (28%). Postnatal exposure to macrolides, lincosamides, and streptogramins significantly reduced the risk of MADs by 16%., Conclusion: Early life exposure to antibiotics is associated with different risk effects on MADs in children. The apparent associations may have been confounded by indication and may not be clinically meaningful., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

- Abstract
The Abecedarian Approach is an internationally recognised early childhood intervention program that has shown long-term positive outcomes for children living in low SES communities. However, there are few studies examining the broader influence of such interventions for young children on the lives of their parents. This article describes the findings of a qualitative study exploring the perceptions and experiences of parents whose children attend an Abecedarian early intervention program located in an urban social housing complex. Eighteen parents whose children had attended the program for a minimum of one year were interviewed. The main themes that emerged were: strengthened relationships between parents and program staff, as well as between parents themselves, particularly supported through the home visitor; increased awareness among parents about early development and of their role in supporting child development; and opportunities for parents' personal growth. The findings suggest that high quality early child intervention programs, such as the Abecedarian Approach, can positively impact the lives of parents., Competing Interests: Declaration of conflicting interest: The authors declare that there is no conflict of interest., (© The Author(s) 2020.)

- Abstract
This cross-sectional study explores the different conditions related to the infestation of ticks in households and the potential risks for rickettsial transmission in Urabá, Colombia. The main outcome of interest was villagers' perception of tick infestation. The data were analyzed using a clog-log mixed regression model. Ticks were collected from infested humans to diagnose infection by spotted fever group rickettsiae (SFGR). In addition, a thematic analysis of qualitative data from key informants concerning knowledge about ticks was conducted. The prevalence of infestation of ticks in households was estimated at 60.99% (95% CI: 51.58-93.51). The multivariate model suggested that households with palm leaf roofs (PR = 1.95; 95% CI: 1.19-2.95), canines (PR = 1.76; 95% CI: 1.21-2.46), rats (PR = 2.19; 95% CI: 1.45-3.08), and with the presence of opossums in areas surrounding the households (PR = 1.51; 95% CI: 1.05-2.10) had a higher prevalence of tick infestation. Two samples of the tick species Amblyomma patinoi were found infected with Rickettsia amblyommatis and Candidatus Rickettsia colombianensi. A thematic analysis provided the names that local community members give to ticks, areas where ticks are common, and the individuals at risk of infestation. The presence of domestic, synanthropic, and wild animals suggests a high risk of the dissemination of ticks inside dwellings and close to them in these rural areas., (© The Author(s) 2020.

- Abstract
Introduction: Indigenous peoples in Canada have endured and continue to experience the impact of colonization by European settlers. The deleterious manifestations of intergenerational historic trauma (HT) are evidenced in the high HIV/AIDS epidemic-related premature mortality rates among Indigenous men, despite the availability of novel highly active antiretroviral therapies (HAARTs). Aim: The aims of this study were to explore the impact of historic trauma (HT) on treatment adherence and health promoting practices among Indigenous men living with HIV, and how resilience was both expressed and mediated by survivor status. Methods: This interpretive description study incorporated a cultural safety lens. Through partnership with the Vancouver Native Health Society, 36 male HT survivors were recruited using purposive and theoretical sampling. They told their lived experiences and health promoting practices with respect to HAART adherence through interviews and a focus group. Results: Two broad categories (findings) emerged: (1) resilience as facilitator of HAART adherence; and (2) differential views on HT's impact. Resilience was expressed through nine concepts. Conclusion: Most Indigenous men in this study demonstrate health promoting behavior, stay on HAART and have better health and well-being even if the environments they live in are marginalized or heavily stigmatizing. This study shows that areas of strength and adaptation, including factors promoting resilience can be harnessed to foster HAART adherence. With a consideration of these areas of strength and adaptation, this study offers implications for research and recommendations to improve treatment-adherent behavior, fostering healing from HT, and reducing HIV/AIDS-related deaths., (Copyright © 2020 Chongo, Lavoie, Mignone, Caron, Harder and Chase.)

- Abstract
This qualitative study explored the fit between on-reserve First Nations community members' conceptualizations of help-seeking for mental health concerns and the Andersen Behavioral Model of Health Services Use. Youth, adults and elders (N = 115) living and or working in eight distinct First Nations communities within a tribal council area in Canada participated in focus groups or individual interviews that were transcribed, coded and then analyzed using a thematic analysis approach informed by grounded theory methodology. Resulting themes were then mapped onto the Andersen Behavioral Model of Health Services Use. Participants' conceptualizations of predisposing characteristics including social structures, health beliefs and mental illness, enabling and impeding resources had a high degree of fit with the model. While perspectives on perceived need for mental health care, and spirituality as a health and lifestyle practice had only moderate fit with the model, these domains could be modified to fit First Nations' interpretations of help-seeking. Participants' perceptions of avoidant strategies and non-use of mental health services, however did not map onto the model. These findings suggest conceptualizations of help-seeking for mental health issues in these First Nations communities are only partially characterized by the Andersen Behavioral Model, suggesting there are a number of considerations to Indigenize the model. Findings also highlight potential explanations for why some members of this population may not access or receive appropriate mental health treatment. Multi-pronged efforts are warranted to link culturally normed pathways of help-seeking with effective mental health supports for First Nations community members in Canada.

- Abstract
Objective: Prenatal care is a vital and important part of a healthy pregnancy, providing many maternal and health benefits. Despite Canada's publically funded health care system with universal access, inadequate rates of prenatal care continue to be observed. As a modifiable risk factor, the process variables that influence satisfaction with prenatal care in Canadian settings have received little attention. The objective of this study was to identify the predictors of satisfaction with prenatal care., Methods: A cross-sectional, descriptive, correlational design was used to examine the relationships between expectations, interpersonal processes of care, the quality of prenatal care, personal characteristics, and the type of provider with overall satisfaction, and with four dimensions of satisfaction. A convenience sample of 216 pregnant women was surveyed using self-administered questionnaires with women in their third trimester. Multiple linear regression analyses were used to identify predictors of satisfaction., Results: The quality of prenatal care and provider interpersonal style together explained 80% of the variance in overall satisfaction. Patient-centered decision-making was a significant predictor of satisfaction with information, while having a midwife was a predictor of satisfaction with system characteristics. Expectations were not related to satisfaction., Conclusions for Practice: Improving quality of care, provider interpersonal style and patient-centered decision making, and improving the structural characteristics of prenatal care may be effective in improving women's satisfaction and utilization of prenatal care.

- Abstract
We conducted a mixed-methods outcome evaluation to examine student experiences and learning in the University of Manitoba's Queen Elizabeth II Diamond Jubilee Scholarship Program in Global and Indigenous Health. Our scholarship program is a bi-directional, 3-month international experiential learning program, including both undergraduate and graduate students, with associated online course focused on community engagement. Students completed a semi-structured narrative report at the conclusion of their funding related to their experience and learning. The Likert questions were analyzed descriptively and student responses to the open-ended questions were utilized for thematic analysis. Also included in this paper is a summary of our lessons learned through program administration. A total of 38 students completed the program between 2016 and 2018, with 95% reporting that they either met or exceeded their goals in the program. Three overarching and inter-related themes emerged in our thematic-analysis of students' narrative reports, including success through relationships and new perspectives, challenges of the unfamiliar , and personal growth through strong emotions . Many students reported personal growth as their greatest success and linked this with new perspectives and awareness of how different contexts shaped their understanding of health issues. Overcoming challenges in their placements contributed to students' confidence in their ability to problem-solve. Overall, students reported value in their experiential learning, which further supports the growing trend to incorporate both experiential learning and formal education in community engagement in public health pedagogy. However, international experiential learning requires considerable financial and human resource commitments to ensure its success.

- Abstract
Experiences during infancy create durable and heritable patterns of social deprivation and illness producing health disparities. This retrospective cohort study of 71 836 infants from Winnipeg, Manitoba, assessed associations between maternal social and economic factors and infant mortality, morbidity, and congenital anomaly. This study found that newborn and postneonatal hospital readmissions are inversely associated with geography. Additionally, social context, including maternal history of child abuse, is associated with infant postneonatal hospital readmissions. Geography and education are associated with infant mortality. Income was not associated with infant mortality or morbidity following adjustment for social support. Interestingly, congenital anomaly rates are 1.2 times more common among 2 parent families and male infants. Understanding associations between infant health and maternal social and economic factors may contribute to interventions and policies to improve health equity.

- Abstract
Aim: This article explores and describes participatory action research (PAR) as a preferred method in addressing nursing practice issues. This is the first study that used PAR with public health nurses (PHNs) in Canada to develop a professional practice model., Background: Participatory action research is a sub-category of action research that incorporates feminist and critical theory with foundations in the field of social psychology. For nurses, critical analysis of long-established beliefs and practices through PAR contributes to emancipatory knowledge regarding the impact of traditional hierarchies on their practice., Design: This study used participatory action, a non-traditional but systematic research method, which assisted participants to develop a solution to a long-standing organizational issue., Method: The stages of generating concerns, participatory action, acting on concerns, reflection and evaluation were implemented from 2012 - 2013 in an urban Canadian city, to develop a professional practice model for PHNs., Findings: Four sub-themes specific to PAR are discussed. These are "participatory action research engaged PHNs in development of a professional practice model;" "the participatory action research cycles of "Look, Think, Act" expanded participants' views;" "participatory action research increased awareness of organizational barriers;" and "participatory action research promoted individual empowerment and system transformation.", Conclusions: This study resulted in individual and system change that may not have been possible without the use of PAR. The focus was engagement of participants and recognition of their lived experience, which facilitated PHNs' empowerment, leadership and consciousness-raising., (© 2018 The Authors.

- Abstract
Indigenous peoples (First Nations, Inuit, and Métis) are currently overrepresented in the HIV epidemic in Canada and are infected at a younger age than those who are not Indigenous. This article presents our findings on the stigma and discrimination (as well as related themes such as disclosure) experienced by Indigenous people who contracted HIV in their youth and live in urban and non-urban settings in Manitoba, Canada. The findings were derived from a qualitative study that sought to understand the experiences and needs of Indigenous people living with HIV (including AIDS). We situate such experiences within a social ecological framework towards developing a better structural understanding of the impacts of stigma and discrimination on the lives of Indigenous people who are HIV positive. Stigma and discrimination caused barriers for Indigenous people living with HIV through inhibiting their ease of access to supports including family, peers, community, and long- and short-term health services. Creative forms of outreach and education that are culturally appropriate and/or rooted in culture were considered to be possibly impactful ways of reducing stigma and discrimination at the community level. Learning from communities who are successfully managing stigma also showed promise for developing new programming., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

- Abstract
Background: Often, research takes place on underserved populations rather than with underserved populations. This approach can further isolate and stigmatize groups that are already made marginalized. What Goes Around is a community-based research project that was led by community members themselves (Peers)., Case Presentation: This research aimed to implement a community-based research methodology grounded in the leadership and growing research capacity of community researchers and to investigate a topic which community members identified as important and meaningful. Chosen by community members, this project explored how safer sex and safer drug use information is shared informally among Peers. Seventeen community members actively engaged as both community researchers and research participants throughout all facets of the project: inception, implementation, analysis, and dissemination of results. Effective collaboration between community researchers, a community organization, and academics facilitated a research process in which community members actively guided the project from beginning to end., Conclusions: The methods used in What Goes Around demonstrated that it is not only possible, but advantageous, to draw from community members' involvement and direction in all stages of a community-based research project. This is particularly important when working with a historically underserved population. Purposeful and regular communication among collaborators, ongoing capacity building, and a commitment to respect the experience and expertise of community members were essential to the project's success. This project demonstrated that community members are highly invested in both informally sharing information about safer sex and safer drug use and taking leadership roles in directing research that prioritizes harm reduction in their communities.

- Abstract
Background: Indigenous young people are currently highly overrepresented in the HIV epidemic in Canada, especially in the Prairie Provinces, such as Manitoba. Understanding HIV-vulnerability in Indigenous peoples must begin with understanding that social determinants are intersectional and linked to the historical legacy of European colonization. In this paper findings that detail the influence of the intersectional social determinants on Indigenous people who become infected with HIV in their youth are presented., Methods: The qualitative research design of phenomenology was used as it afforded the opportunity to understand Indigenous young people from their frames of reference and experiences of reality, resulting in a phenomenological understanding of their perspectives and experiences of the early years of living with HIV. A total of 21 Indigenous young people took part open-ended interviews., Results: The stories that the Indigenous young people shared revealed their deeply interconnected social worlds, and how social determinants including abuse, trauma, being part of the child welfare system, and housing and food security were connected throughout various stages of their lives. Such stages included childhood, adolescence and young adulthood (the time of HIV infection), and later adulthood for older participants with the social determinants having multiple influences on their health trajectories., Conclusions: The findings highlight the need for policies and programs that are broadly focused, addressing multiple social determinants together. Overall, there needs to be more emphasis on the multiple social determinants in the life situations of all Indigenous youth. Reducing the health and social disparities in Indigenous youth is key to reducing the number of young Indigenous people diagnosed with HIV. The findings also shed light on the importance of listening to young Indigenous people who have experienced HIV diagnosis and life following diagnosis.

- Abstract
Purpose Documents articulating public health nurses' (PHNs') roles, including Canadian standards and competencies, depict a broad focus working at multiple levels to improve population outcomes through the promotion of health equity. Conversely, Canadian experts depict a looming crisis, based on the rising disconnect between daily activities and ideal practice. While perfectly positioned, PHNs' skills and abilities are under-utilized and largely invisible. The intention of this study was to develop a model to support the full scope of equity-focused PHN practice. Method A participatory action research approach was used. Qualitative data were gathered using semistructured interview guides during audio-recorded meetings. The data were coded into central themes using content analysis and constant comparison. A researcher reflexive journal and field notes were kept. A significant feature was full participant involvement. Results The outcome was a professional practice model to reframe the PHN role to focus on population health and equity. The model was imperative in promoting full scope of practice, dealing with workload pressures, and describing PHNs' value within the organization and broader health system. Conclusion Professional practice models hold promise as frameworks to depict autonomous practice activities, situated within organizations and healthcare systems, and underpinned by nursing knowledge.

- Abstract
Objective: the primary objective for this study was to explore women's experiences of choosing to plan a birth at an out-of-hospital birth centre. We sought to understand how women make the choice to plan for an out-of-hospital birth and the meaning that women ascribe to this decision-making process., Design, Setting, and Participants: a qualitative phenomenological study was conducted in Winnipeg, Canada with a sample of seventeen post partum women who represent the socio-demographic characteristics of the actual users of the Birth Centre in Winnipeg. The women participated in semistructured interviews. Through a feminist perspective and using interpretative phenomenological analysis (IPA), each participant's experience of birthplace decision-making was explored., Findings: six themes emerged through the analysis: (1) Making the decision in the context of relationships; (2) Exercising personal agency; (3) An expression of one's ideology; (4) Really thinking it through; (5) Fitting into the eligibility criteria; and (6) The psychology of the space. The findings suggested that a woman's sense of safety was related to each of these themes., Key Conclusions and Implications for Practice: the birth centre decision-making experience has many similarities to the homebirth decision-making process. The visceral impact of the physical design of the facility plays an important role and differentiates the birth centre decision from other birth setting options. The concept of relational autonomy was emphasised in this study, in that women make the decision in the context of their relationships with their midwives and partners. The study has implications for midwifery practice and health-care policy related to: client education on birth settings, design of birth environments, validation of the birth centre concept, and upholding the women-centred midwifery model of care. The study highlighted the importance of increasing access to out-of-hospital birth centres., (Copyright © 2016 Elsevier Ltd. All rights reserved.)

- Abstract
The article examines the use of bilingual guides to decrease cultural barriers to health care access in the Wayuu indigenous communities of Colombia. Within a larger project on HIV carried out between 2012 and 2014, 24 interviews were conducted with key actors in the administrative and health areas, including Wayuu bilingual guides. As a result of the qualitative analysis, the study identified three cultural barriers to health care access: a) language; b) the Wayuu worldview regarding the body, health, and illness; and c) information about sexual and reproductive health and HIV not adapted to the Wayuu culture. The study identifies the bilingual guides as key actors in reducing these barriers and concludes with a discussion of the role of the guides, the tensions inherent to their work, and the complexity of their contributions as cultural mediators.

- Abstract
Background: In 2000, midwifery was regulated in the Canadian Province of Manitoba. Since the establishment of the midwifery program, little formal research has analyzed the utilization of regulated midwifery services. In Manitoba, the demand for midwifery services has exceeded the number of midwives in practice. The specific objective of this study was to explore factors influencing the implementation and utilization of regulated midwifery services in Manitoba., Methods: The case study design incorporated qualitative exploratory descriptive methods, using data derived from two sources: interviews and public documents. Twenty-four key informants were purposefully selected to participate in semi-structured in-depth interviews. All documents analyzed were in the public domain. Content analysis was employed to analyze the documents and transcripts of the interviews., Results: The results of the study were informed by the Behavioral Model of Health Services Use. Three main topic areas were explored: facilitators, barriers, and future strategies and recommendations. The most common themes arising under facilitators were funding of midwifery services and strategies to integrate the profession. Power and conflict, and lack of a productive education program emerged as the most prominent themes under barriers. Finally, future strategies for sustaining the midwifery profession focused on ensuring avenues for registration and education, improving management strategies and accountability frameworks within the employment model, enhancing the work environment, and evaluating both the practice and employment models. Results of the document analysis supported the themes arising from the interviews., Conclusion: These findings on factors that influenced the implementation and integration of midwifery in Manitoba may provide useful information to key stakeholders in Manitoba, as well as other provinces as they work toward successful implementation of regulated midwifery practice. Funding for new positions and programs was consistently noted as a successful strategy. While barriers such as structures of power within Regional Health Authorities and inter and intra-professional conflict were identified, the lack of a productive midwifery education program emerged as the most prominent barrier. This new knowledge highlights issues that impact the ongoing growth and capacity of the midwifery profession and suggests directions for ensuring its sustainability.

Nestin expression marks stem and progenitor cells of the neural lineage. Transgenic mouse lines, originally generated to identify neural stem cells, can also help to identify, track, and isolate stem and progenitor cells in a range of tissues of the ectodermal, endodermal, and mesodermal origin. Here, we describe the generation of transgenic mouse lines expressing fluorescent proteins (FP) under the control of critical regulatory elements of the nestin gene and their use for identifying and analyzing adult stem and progenitor cells in various tissues.

Non-basic azolotriazinones were explored using an empirical free brain exposures-driven approach to identify potent MCHR1 antagonists for evaluation in in vivo efficacy studies. An optimized lead from this series, 1j (rMCHR1 Ki=1.8 nM), demonstrated a 6.9% reduction in weight gain relative to vehicle in a rat model at 30 mg/kg after 4 days of once-daily oral treatment as a glycine prodrug. Despite a promising efficacy profile, an assessment of the biliary toxicity risk of this compound rendered this compound non-progressible., (Copyright © 2015 Elsevier Ltd. All rights reserved.)

- Abstract
After decades of believing the heart loses the ability to regenerate soon after birth, numerous studies are now reporting that the adult heart may indeed be capable of regeneration, although the magnitude of new cardiac myocyte formation varies greatly. While this debate has energized the field of cardiac regeneration and led to a dramatic increase in our understanding of cardiac growth and repair, it has left much confusion in the field as to the prospects of regenerating the heart. Studies applying modern techniques of genetic lineage tracing and carbon-14 dating have begun to establish limits on the amount of endogenous regeneration after cardiac injury, but the underlying cellular mechanisms of this regeneration remained unclear. These same studies have also revealed an astonishing capacity for cardiac repair early in life that is largely lost with adult differentiation and maturation. Regardless, this renewed focus on cardiac regeneration as a therapeutic goal holds great promise as a novel strategy to address the leading cause of death in the developed world., (Copyright © 2015 the American Physiological Society.)

- Abstract
Objective: To describe the trends in numbers of midwives and midwifery-attended births and the characteristics of women who used midwifery health care services in Manitoba from 2001-2002 to 2009-2010., Methods: We conducted a quantitative descriptive analysis using population-based, de-identified administrative data from the Population Health Research Data Repository at the Manitoba Centre for Health Policy in Winnipeg, Manitoba to study the use of midwifery care. Trends in the numbers of practising and non-practising midwives were based on data from the College of Midwives of Manitoba registries and its annual reports., Results: There were 132,123 births in Manitoba during this time frame. Of those births, 6326 (4.8%) were midwife-attended births. There was modest growth in the overall proportion of midwife-attended births and in the number of midwives over the 10-year time period. The number of midwife-attended hospital births increased from 308 to 612 between 2001-2002 and 2009-2010, while the number of home births increased from 97 to 127. Most women who received midwifery care were in the 20- to 34-year age group and were multiparous., Conclusion: The volume and distribution of midwifery services in Manitoba has slowly increased. The proportion of births attended by midwives continues to fall short of the goals set by the original human resource strategy, which projected that by 2005, 14% of births would be attended by midwives. Further research is needed to analyze the factors that have influenced the growth and sustainability of the midwifery profession in this province.

- Abstract
We sought to understand the support networks of people living with HIV (PLWH) in the Canadian cities of Winnipeg and Regina, particularly of their network of caregivers and with a focus on people from disadvantaged and/or stigmatized communities. Using a variation of the Photovoice method, 31 study participants took photographs of their everyday realities and were then interviewed. Among the findings was the heavy reliance on institutional caregivers and on nonhuman sources of support. There was evidence of peer-to-peer networks of care, but the strongest connections were with their formal caregivers. HIV as a chronic condition among disadvantaged and/or stigmatized groups requires paying special attention to informal and formal care dynamics and to where social or family networks cannot meet the basic needs. Honing in on and enhancing these features through programs and services can only improve the situation of stigmatized yet hopeful and resilient PLWH., (Copyright © 2015 Association of Nurses in AIDS Care.

Identification of MCHR1 antagonists with a preclinical safety profile to support clinical evaluation as antiobesity agents has been a challenge. Our finding that a basic moiety is not required for MCHR1 antagonists to achieve high affinity allowed us to explore structures less prone to off-target activities such as hERG inhibition. We report the SAR evolution of hydroxylated thienopyrimidinone ethers culminating in the identification of 27 (BMS-819881), which entered obesity clinical trials as the phosphate ester prodrug 35 (BMS-830216).

43. Disentangling the Correlates of Drug Use in a Clinic and Community Sample: A Regression Analysis of the Associations between Drug Use, Years-of-School, Impulsivity, IQ, Working Memory, and Psychiatric Symptoms.

Heyman GM, Dunn BJ, and Mignone J
- Abstract
Years-of-school is negatively correlated with illicit drug use. However, educational attainment is positively correlated with IQ and negatively correlated with impulsivity, two traits that are also correlated with drug use. Thus, the negative correlation between education and drug use may reflect the correlates of schooling, not schooling itself. To help disentangle these relations we obtained measures of working memory, simple memory, IQ, disposition (impulsivity and psychiatric status), years-of-school and frequency of illicit and licit drug use in methadone clinic and community drug users. We found strong zero-order correlations between all measures, including IQ, impulsivity, years-of-school, psychiatric symptoms, and drug use. However, multiple regression analyses revealed a different picture. The significant predictors of illicit drug use were gender, involvement in a methadone clinic, and years-of-school. That is, psychiatric symptoms, impulsivity, cognition, and IQ no longer predicted illicit drug use in the multiple regression analyses. Moreover, high risk subjects (low IQ and/or high impulsivity) who spent 14 or more years in school used stimulants and opiates less than did low risk subjects who had spent <14 years in school. Smoking and drinking had a different correlational structure. IQ and years-of-school predicted whether someone ever became a smoker, whereas impulsivity predicted the frequency of drinking bouts, but years-of-school did not. Many subjects reported no use of one or more drugs, resulting in a large number of "zeroes" in the data sets. Cragg's Double-Hurdle regression method proved the best approach for dealing with this problem. To our knowledge, this is the first report to show that years-of-school predicts lower levels of illicit drug use after controlling for IQ and impulsivity. This paper also highlights the advantages of Double-Hurdle regression methods for analyzing the correlates of drug use in community samples.

Little research can be found describing social aspects of aging with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) in Canada specifically, despite an overall increase in an aging population and increased numbers of those aging with HIV/AIDS. A systematic literature review was conducted with a selective focus on social aspects related to older adults who are living with or at risk for contracting HIV/AIDS. The primary themes that emerged in the literature are ageism and stigma, gender, mental health, and social supports. Recommendations for future research regarding prevention and education of risks for older adults and programming suitable for a wide range of audiences are presented.

- Abstract
It has been theorized that suicide behaviours amongst indigenous peoples may be an outcome of mass trauma experienced as a result of colonization. In Canada, qualitative evidence has suggested that the Indian Residential School System set in motion a cycle of trauma, with some survivors reporting subsequent abuse, suicide, and other related behaviours. It has been further postulated that the effects of trauma can also be passed inter-generationally. Today, there are four generations of Canadian First Nations residential school survivors who may have transmitted the trauma they experienced to their own children and grandchildren. No empirical study has ever been undertaken to demonstrate this dynamic. This study is therefore the first to investigate whether a direct or indirect exposure to Canada's residential school system is associated with trauma and suicide behaviour histories. Data were collected in 2002/2003 from a representative sample of Manitoba, Canada, First Nations adults (N = 2953), including residential (N = 611) and non-residential school attendees (N = 2342). Regression analyses showed that for residential school attendees negative experiences in residential school were associated with a history of abuse, and that this history and being of younger age was associated with a history of suicide thoughts, whereas abuse history only was associated with a history of suicide attempts. For First Nations adults who did not attend a residential school, we found that age 28-44, female sex, not having a partner, and having a parent or grandparent who attended a residential school was associated with a history of abuse. This history, along with age and having had a parent or grandparent who attended residential school was associated with a history of suicide thoughts and attempts. In conclusion, this is the first study to empirically demonstrate, at the population level, the mental health impact of the residential school system on survivors and their children., (Copyright © 2012 Elsevier Ltd.

- Abstract
It is generally surmised that community stressors have an incubating effect for a variety of diagnoses on maternal and child health. This is of public health significance, as children of mothers facing long-term distress were found to have a 60% higher risk for asthma diagnosis at age 7 in Manitoba, Canada. Our objective was to determine the association of community stressors with childhood asthma prevalence in Winnipeg, Canada from participants who completed the Study of Asthma, Genes and the Environment (SAGE) survey administered in 2002-2003 to a birth cohort from 1995. Measures of community socioeconomic makeup and community disorder with rank ordinalized by quintile at the census tract level were obtained from the 1996 Canada Census. Crime data (annual incidence per 10,000 persons) by neighbourhood profile for 2001 was provided by the Winnipeg Police Service. Dichotomous caregiver report of child asthma along with other indicators from the geocoded SAGE survey allowed linkage to 23 neighbourhood profiles. Multilevel logistic regression analyses were performed to estimate the effect of community stressors on childhood asthma prevalence for birth and non-birth home children (N = 1472) and children resident of birth homes at age 7 or 8 (N = 698). After adjusting for individual risk factors, children resident of birth homes in a high thefts over $5,000 neighbourhood profile were twice as likely (Adjusted OR, 2.05; 95% CI, 1.11-3.81) to have report of asthma compared to children in a lower thefts over $5,000 profile, with community thefts over $5,000 explaining over half of the observed neighbourhood variation in asthma.

- Abstract
The high rate of domestic violence in Aboriginal communities points to the need to explore new ways of understanding how this violence occurs in its context and to seek new and creative ways of preventing the perpetuation of this vicious cycle. The Life Story Board (LSB) is a game board with sets of cards, markers, and a notation system with which to construct a visual representation of someone's life experience at personal, family, and community levels. Initially invented as an interview tool in an expressive art program for war-affected children, the LSB has broader potential for use by those working with youth, adults, and families in a variety of contexts, and as a tool for program evaluation and applied research. This article describes LSB methods and how they may apply in the context of Canadian First Nations, Inuit, and Métis community efforts to respond to, understand, and prevent domestic violence.

- Abstract
The practice of integrating western and traditional indigenous medicine is fast becoming an accepted and more widely used approach in health care systems throughout the world. However, debates about intercultural health approaches have raised significant concerns. This paper reports findings of five case studies on intercultural health in Chile, Colombia, Ecuador, Guatemala, and Suriname. It presents summary information on each case study, comparatively analyzes the initiatives following four main analytical themes, and examines the case studies against a series of the best practice criteria.

- Abstract
The intermediate filament nestin is localized postsynaptically at rodent neuromuscular junctions. The protein forms a filamentous network beneath and between the synaptic gutters, surrounds myofiber nuclei, and is associated with Z-discs adjacent to the junction. In situ hybridization shows that nestin mRNA is synthesized selectively by synaptic myonuclei. Although weak immunoreactivity is present in myelinating Schwann cells that wrap the preterminal axon, nestin is not detected in the terminal Schwann cells (tSCs) that cover the nerve terminal branches. However, after denervation of muscle, nestin is upregulated in tSCs and in SCs within the nerve distal to the lesion site. In contrast, immunoreactivity is strongly downregulated in the muscle fiber. Transgenic mice in which the nestin neural enhancer drives expression of a green fluorescent protein (GFP) reporter show that the regulation in SCs is transcriptional. However, the postsynaptic expression occurs through enhancer elements distinct from those responsible for regulation in SCs. Application of botulinum toxin shows that the upregulation in tSCs and the loss of immunoreactivity in muscle fibers occurs with blockade of transmitter release. Extrinsic stimulation of denervated muscle maintains the postsynaptic expression of nestin but does not affect the upregulation in SCs. Thus, a nestin-containing cytoskeleton is promoted in the postsynaptic muscle fiber by nerve-evoked muscle activity but suppressed in tSCs by transmitter release. Nestin antibodies and GFP driven by nestin promoter elements serve as excellent markers for the reactive state of SCs. Vital imaging of GFP shows that SCs grow a dynamic set of processes after denervation.

- Abstract
Nitric oxide (NO) has a profound role in the generation, differentiation, survival, and physiology of neurons. We have created a novel transgenic model to study the action of NO in the adult brain, in which the neuronal isoform of NO synthase (nNOS) is expressed under control of the promoter of the calcium-calmodulin multifunctional kinase IIalpha (CaMKIIalpha) gene. We show that the transgenic nNOS RNA and protein are expressed in the cortex, the hippocampus and the striatum of the transgenic mice. We also show that expression of several genes involved in the protection of neurons from oxidative stress and cell death is not affected in neurons of the transgenic mice. Furthermore, generation of new cells is depressed in the neurogenic brain areas in transgenics. In addition, we analyze gene expression in the hippocampus of the transgenic animals using microarray RNA profiling and Q-PCR. Our experiments describe specific changes in cell division and gene activity in the CaMKII-nNOS transgenic model and demonstrate its utility for studying the action of NO in the adult brain.
