RESUMEN

The growing issue of housing affordability is an increasing challenge worldwide as the financialization of housing markets undermines housing as a basic human right. One of the most vulnerable segments of the population affected by rising housing costs are older, low-income, females. Drawing on qualitative interviews with older women, we explore lived experiences of housing insecurity using a feminist political ecology perspective. Our findings reveal substantial challenges as well as creative solutions being employed by these women to stay in place. We conclude that more targeted and age- and gender-inclusive housing policies, programs, supports and services are critically needed.

RESUMEN

BACKGROUND: Androgen deprivation therapy (ADT) improves outcomes in unfavorable-risk prostate cancer (PCa) treated with radiation therapy (RT). It was hypothesized that replacing luteinizing hormone-releasing hormone (LHRH) agonists with a 5-α-reductase inhibitor (5-ARI) would improve hormonal health-related quality of life (HRQOL) without differentially suppressing androgen-responsive (AR) gene expression. METHODS: Patients with localized unfavorable-risk PCa, aged ≥70 years or Charlson Comorbidity Index score ≥2 were treated with oral ADT (oADT), consisting of 4 months of bicalutamide, a 5-ARI, and RT at 78 Gy. The primary end point was Expanded Prostate Cancer Index Composite HRQOL at 6 months ≤30%, and improvement compared with a synchronous standard of care (SOC) cohort receiving 4 months of bicalutamide and long-term LHRH agonist with RT. RNA sequencing was performed from matched pre-/post-ADT prostate tumor biopsies in a subset of men. Differential gene and pathway expressional changes were examined using gene set enrichment. RESULTS: Between 2011 and 2018, 40 and 30 men were enrolled in the oADT and SOC cohorts, respectively. Median follow-up was 40 months. Those with ≤30% decline in hormonal HRQOL at 6 months was 97% (oADT) and 93% (SOC). The average 6-month hormonal decline was 1% (oADT) versus 12% (SOC; P = .04). The 4-year freedom from biochemical failure was 88% (oADT) versus 81% (SOC; P = .48). RNA sequencing (n = 9) showed similar numbers of downregulated and upregulated genes between the treatment groups (fold-change = 2; false-discovery rate-adjusted P ≤ .05). Both treatments comparably decreased the expression of 20 genes in canonical androgen receptor signaling. CONCLUSIONS: For men with PCa undergoing RT, oral versus standard ADT may improve 6-month QOL and appears to have a similar impact on androgen-responsive gene expression.

RESUMEN

BACKGROUND: 'Whole-person' palliative approaches to care (PAC) are important for enhancing the quality of life of residents with life-limiting conditions in long-term care (LTC). This research is part of a larger, four province study, the 'SALTY (Seniors Adding Life to Years)' project to address quality of care in later life. A Quality Improvement (QI) project to integrate a PAC (PAC-QI) in LTC was implemented in Western Canada in four diverse facilities that varied in terms of ownership, leadership models, bed size and geography. Two palliative 'link nurses' were hired for 1 day a week at each site over a two-year time frame to facilitate a PAC and support education and training. This paper evaluates the challenges with embedding the PAC-QI into LTC, from the perspectives of the direct care, or front-line team members. Sixteen focus groups were undertaken with 80 front-line workers who were predominantly RNs/LPNs (n = 25), or Health Care Aides (HCAs; n = 32). A total of 23 other individuals from the ranks of dieticians, social workers, recreation and rehabilitation therapists and activity coordinators also participated. Each focus group was taped and transcribed and thematically analyzed by research team members to develop and consolidate the findings related to challenges with embedding the PAC. RESULTS: Thematic analyses revealed that front-line workers are deeply committed to providing high quality PAC, but face challenges related to longstanding conditions in LTC notably, staff shortages, and perceived lack of time for providing compassionate care. The environment is also characterized by diverse views on what a PAC is, and when it should be applied. Our research suggests that integrated, holistic and sustainable PAC depends upon access to adequate resources for education, training for front-line care workers, and supportive leadership. CONCLUSIONS: The urgent need for integrated PAC models in LTC has been accentuated by the current COVID-19 pandemic. Consequently, it is more imperative than ever before to move forwards with such models in order to promote quality of care and quality of life for residents and families, and to support job satisfaction for essential care workers.

RESUMEN

INTRODUCTION: Understanding rural-urban differences, and understanding levels of life satisfaction in rural populations, is important in planning social and healthcare services for rural populations. The objectives of this study were to determine patterns of life satisfaction in Canadian rural populations aged 45-85 years, to determine rural-urban differences in life satisfaction across a rural-urban continuum after accounting for potential confounding factors and to determine if related social and health factors of life satisfaction differ in rural and urban populations. METHODS: A secondary analysis was conducted using data from an ongoing population-based cohort study, the Canadian Longitudinal Study on Aging. A cross-sectional sample from the baseline wave of the tracking cohort was used, which was intended to be as generalizable as possible to the Canadian population. Four geographic areas were compared on a rural-urban continuum: rural, mixed (indicating some rural, but could also include some peri-urban areas), peri-urban, and urban. Life satisfaction was measured using the Satisfaction with Life Scale and dichotomized as satisfied versus dissatisfied. Other factors considered were province of residence, age, sex, education, marital status, living arrangement, household income, and chronic conditions. These factors were self-reported. Bivariate analyses using χ2 tests were conducted for categorical variables. Logistic regression models were constructed with the outcome of life satisfaction, after which a series of models were constructed, adjusting for province of residence, age, and sex, for sociodemographic factors, and for health-related factors. To report on differences in the factors associated with life satisfaction in the different areas, logistic regression models were constructed, including main effects for the variable of interest, for the variable rurality, and for the interaction term between these two variables. RESULTS: Individuals living in rural areas were more satisfied with life than their urban counterparts (odds ratio (OR)=1.23; 95% confidence interval (CI): 1.13-1.35), even after accounting for the effect of confounding sociodemographic and health-related factors (OR=1.32, 95%CI: 1.19-1.45). Those living in mixed (OR=1.30, 95%CI: 1.14-1.49) and peri-urban (OR=1.21, 95%CI: 1.07-1.36) areas also reported being more satisfied than those living in urban areas. In addition, a positive association was found between life satisfaction and age, as well as between life satisfaction and being female. A strong graded association was noted between income and life satisfaction. Most chronic conditions were associated with lower life satisfaction. Finally, no major interaction was noted between rurality and each of the previously mentioned different factors associated with life satisfaction. CONCLUSION: Rural-urban differences in life satisfaction were found, with higher levels of life satisfaction in rural populations compared to urban populations. Preventing and treating common chronic illness, and also reducing inequalities in income, may prove useful to improving life satisfaction in both rural and urban areas. Studies of life satisfaction should consider rurality as a potential confounding factor in analyses of life satisfaction within and across societies.

RESUMEN

Interpretations of family carer empowerment in much nursing research, and in home-care practice and policy, rarely attend explicitly to families' choice or control about the nature, extent or length of their involvement, or control over the impact on their own health. In this article, structural empowerment is used as an analytic lens to examine home-care nurses' interactions with families in one Western Canadian region. Data were collected from 75 hrs of fieldwork in 59 interactions (18 nurses visiting 16 families) and interviews with 12 nurses and 11 family carers. Generally, nurses prioritized client empowerment, and their practice with families appeared oriented to supporting their role and needs as carers (i.e. rather than as unique individuals beyond the caring role), and reinforcing the caring role through validation and recognition. Although families generally expressed appreciation for these interactions, a structural empowerment lens illustrates how the broad context of home care shapes the interpretation and practice of empowerment in ways that can, paradoxically, be disempowering for families. Opportunities to effectively support family choice and control when a client is being cared for at home are discussed.

RESUMEN

Objectives The use of antipsychotics, mainly to address the behavioral and psychological symptoms of dementia (BPSD), remains a common and frequent practice in long-term care facilities (LTCFs) despite their associated risks. The objective of this study was to explore the association between social engagement (SE) and the use of antipsychotics in addressing the BPSD in newly admitted residents to LTCFs. Methods A cross-sectional study was undertaken using administrative data, primarily the Resident Assessment Instrument Minimum Data Set (Version 2.0) that collected between 2008 and 2011 (Fraser Health region, British Columbia, Canada). The data analysis conducted on a sample of 2,639 newly admitted residents aged 65 or older with a diagnosis of Alzheimer's disease or other dementias as of their first full or first quarterly assessment. Multivariate logistic regression analyses were undertaken to predict antipsychotic use based on SE. Results SE was found to be a statistically significant predictor of antipsychotic use when controlling for sociodemographic variables (odds ratio ( OR) = .86, p < .0001, confidence interval (CI) [0.82, 0.90]). However, the association disappeared when controlling for health variables ( OR = .97, p = .21, CI [0.97, 1.0]). Conclusion The prediction of antipsychotic use in newly admitted residents to LTCFs by SE is complex. Further research is warranted for further examination of the association of antipsychotic use in newly admitted residents to LTCFs.

RESUMEN

Pompe disease is a neuromuscular disease resulting from deficiency in acid α-glucosidase (GAA), results in cardiac, skeletal muscle, and central nervous system (CNS) pathology. Enzyme replacement therapy (ERT) has been shown to partially correct cardiac and skeletal muscle dysfunction. However, ERT does not cross the blood-brain barrier and progressive CNS pathology ensues. We tested the hypothesis that intrapleural administration of recombinant adeno-associated virus (rAAV9)-GAA driven by a cytomegalovirus (CMV) or desmin (DES) promoter would improve cardiac and respiratory function in Gaa(-/-) mice through a direct effect and retrograde transport to motoneurons. Cardiac magnetic resonance imaging revealed significant improvement in ejection fraction in rAAV9-GAA-treated animals. Inspiratory phrenic and diaphragm activity was examined at baseline and during hypercapnic respiratory challenge. Mice treated with AAV9 had greater relative inspiratory burst amplitude during baseline conditions when compared with Gaa(-/-). In addition, efferent phrenic burst amplitude was significantly correlated with diaphragm activity in both AAV9-DES and AAV9-CMV groups but not in Gaa(-/-). This is the first study to indicate improvements in cardiac, skeletal muscle, and respiratory neural output following rAAV administration in Pompe disease. These results further implicate a role for the CNS in Pompe disease pathology and the critical need to target the neurologic aspects in developing therapeutic strategies.

RESUMEN

STUDY BACKGROUND: The practice of acute care nurses is shaped by organizational factors such as lack of privacy, heavy workloads, unclear roles, lack of time, and lack of specific policies and procedures. We know little about the social and organizational structures and processes that influence nurses' uptake of valuable patient-centered discussions like advance care planning (ACP). ACP is beneficial for patients, their substitute decision makers, and healthcare providers. PURPOSE: To describe the operational, organizational, and societal influences shaping nurses' ACP work in acute care settings. METHODS: This ethnographic study purposively sampled 14 registered nurses and 9 administrators who worked in two acute care hospitals in Northeastern Ontario. Methods consisted of 23 open-ended, semi-structured interviews, 20 hours of observational fieldwork, and a collection of publicly available organizational documents. Data were inductively analyzed using an iterative constant comparative approach. RESULTS: Nurses were challenged to meet multiple competing demands, leaving them to scramble to manage complex and critically ill acute care patients while also fulfilling organizational tasks aligned with funding metrics, accreditation, and strategic planning priorities. Such factors limited nurses' capacity to engage their patients in ACP. CONCLUSIONS: Acute care settings that align patient values and medical treatment need to foster ACP practices by revising organizational policies and processes to support this outcome, analyzing the tasks of healthcare providers to determine who might best address it, and budgeting how to support it with additional resources.

RESUMEN

The COVID-19 pandemic exposed long-standing inequities in Canada's long-term residential care (LTRC) sector with life-threatening consequences. People from marginalized groups are overrepresented among those who live in, and work in LTRC facilities, yet their voices are generally silenced in LTRC research. Concerns about these silenced voices have sparked debate around ways to change LTRC policy to better address long-standing inequities and enhance the conditions that foster dignity for those who live and work in LTRC. Weaving an analysis of historical and cultural attitudes about LTRC, and promising strategies for engaging people with lived experience, we argue that the voices of people with lived experience of life and work (paid and unpaid) in LTRC are essential for ethically and effectively shifting long-standing inequities. Lessons from a 4-year, national, multi-disciplinary research study, known as the Seniors Adding Life to Years (SALTY) project, suggest that resident-determined quality of life can be prioritized by centring the perspectives of residents, their family/friends, direct care workers, volunteers, and people living with dementia in the research process. Accordingly, we highlight strategies to include these voices so that meaningful and impactful system change can be realized.


This article argues that long-term residential care facilities in Canada have a long history of perpetuating social inequalities, beginning with seventeenth century poor houses and almshouses, from which long-term residential care facilities evolved in North America. We highlight that those who currently reside in long-term residential care are more likely to be people with less social power­for example women, people living with dementia, and people with low-income. These residents are rarely included in research projects as co-designers of research, co-producers of knowledge, or experts on the realities of long-term residential care. We explore strategies for addressing these underrepresented voices and inequalities in research by highlighting promising examples of resident, family, and worker-engagement emerging from a pre-pandemic to early pandemic pan-Canadian research project on quality of life in long-term residential care. We argue that long-term residential care residents, their family/friend caregivers, people living with dementia, and direct care workers have voices that are essential in residential care design and research engagement strategies. By prioritizing these voices in research, we can better amplify their critical perspectives in broader policy and decision-making processes that guide meaningful and impactful system change.

RESUMEN

Pompe disease is an autosomal recessive metabolic myopathy caused by the deficiency of the lysosomal enzyme acid alpha-glucosidase and results in cellular lysosomal and cytoplasmic glycogen accumulation. A wide spectrum of disease exists from hypotonia and severe cardiac hypertrophy in the first few months of life due to severe mutations to a milder form with the onset of symptoms in adulthood. In either condition, the involvement of several systems leads to progressive weakness and disability. In early-onset severe cases, the natural history is characteristically cardiorespiratory failure and death in the first year of life. Since the advent of enzyme replacement therapy (ERT), the clinical outcomes have improved. However, it has become apparent that a new natural history is being defined in which some patients have substantial improvement following ERT, while others develop chronic disability reminiscent of the late-onset disease. In order to improve on the current clinical outcomes in Pompe patients with diminished clinical response to ERT, we sought to address the cause and potential for the treatment of disease manifestations which are not amenable to ERT. In this review, we will focus on the preclinical studies that are relevant to the development of a gene therapy strategy for Pompe disease, and have led to the first clinical trial of recombinant adeno-associated virus-mediated gene-based therapy for Pompe disease. We will cover the preliminary laboratory studies and rationale for a clinical trial, which is based on the treatment of the high rate of respiratory failure in the early-onset patients receiving ERT.

RESUMEN

PURPOSE: To document the prevalence of functional impairment in middle-aged and older adults from rural regions and to determine urban-rural differences. METHODS: We have conducted a secondary analysis using data from an ongoing population-based cohort study, the Canadian Longitudinal Study on Aging (CLSA). We used a cross-sectional sample from the baseline wave of the "tracking cohort." The definition of rurality was the same as the one used in the CLSA sampling frame and based on the 2006 census. This definition includes rural areas, defined as all territory lying outside of population centers, and population centers, which collectively cover all of Canada. We grouped these into "Urban," "Peri-urban," "Mixed" (areas with both rural and urban areas), and "Rural," and compared functional status across these groups. Functional status was measured using the Older Americans Resource Survey (OARS) and categorized as not impaired versus having any functional impairment. Logistic regression models were constructed for the outcome of functional status and adjusted for covariates. FINDINGS: No differences were found in functional status between those living in rural, mixed, peri-urban, and urban areas in unadjusted analyses and in analyses adjusting for sociodemographic and health-related factors. There were no rural-urban differences in any of the individual items on the OARS scales. CONCLUSIONS: We found no rural-urban differences in functional status.

RESUMEN

Introduction: Obesity is an important public health concern, and large studies of rural-urban differences in prevalence of obesity are lacking. Our purpose is to compare body mass index (BMI) and obesity in Canada using an expanded definition of rurality. Methods: A cross-sectional analysis of self-reported BMI across diverse communities of Canadians aged 45-85 years was conducted using data from the Canadian Longitudinal Study on Aging (CLSA), a national sample representative of community-dwelling residents. Rurality was identified in the CLSA based on residential postal codes, which were divided into 4 categories: urban, peri-urban, mixed and rural. Logistic regression models were constructed to calculate adjusted odds ratios (aORs) with 95% confidence intervals (95% CIs) between obesity (BMI ≥30 kg/m2 from self-reported weight and height) and rurality, adjusting for age, sex, province, marital status, number of residents in household and household income. Results: Twenty-one thousand one hundred and twenty-six Canadian residents aged 45-85 years, surveyed during 2010-2015, were included. 26.8% were obese. Obesity was less prevalent amongst urban (25.2%) than rural (30.3%, P < 0.0001), mixed (28.7%, P < 0.0001) or peri-urban communities (28.1%, P < 0.0001). When compared to urban areas, the aOR (95% CI) for obesity was 1.09 (1.00-1.20) in rural regions and 1.20 (1.08-1.35) in peri-urban settings. In areas of mixed urban and rural residence, the aOR was 1.12 (0.99-1.27). Conclusion: One in four Canadian adults were obese. Living in a non-urban setting is an independent risk factor for obesity. Rural-urban health disparities could underlie rural-urban differences, but further research is needed.


Résumé Introduction: L'obésité est un important problème de santé publique et des études de grande envergure sur les différences de prévalence de l'obésité entre les régions rurales et urbaines font défaut. Notre objectif est de comparer l'indice de masse corporelle (IMC) et l'obésité au Canada en utilisant une définition élargie de la ruralité. Méthodes: Une analyse transversale de l'IMC autodéclaré dans diverses communautés de Canadiens âgés de 45 à 85 ans a été réalisée à l'aide des données de l'Étude longitudinale canadienne sur le vieillissement (ELCV); un échantillon national représentatif des résidents vivant en communauté. Dans l'ELCV, la ruralité a été identifiée à partir des codes postaux résidentiels, qui ont été divisés en 4 catégories: urbain, périurbain, mixte et rural. Des modèles de régression logistique ont été construits pour calculer les rapports de cotes ajustés (RCa) avec des intervalles de confiance à 95% (95% IC) entre l'obésité (IMC ≥30 kg/m2 à partir du poids et de la taille autodéclarés) et la ruralité, en tenant compte de l'âge, du sexe, de la province, de l'état civil, du nombre de résidents dans le ménage et du revenu du ménage. Résultats: 21 126 résidents canadiens âgés de 45 à 85 ans, interrogés au cours de la période 2010-2015, ont été inclus. 26,8% étaient obèses. L'obésité était moins répandue dans les communautés urbaines (25,2%) que rurales (30,3%, P < 0,0001), mixtes (28,7%, P < 0,0001) ou périurbaines (28,1%, P < 0,0001). Par rapport aux zones urbaines, le RCa (95% IC) pour l'obésité était de 1,09 (1,00, 1,20) dans les régions rurales, et de 1,20 (1,08, 1,35) dans les milieux périurbains. Dans les zones de résidence mixte urbaine et rurale, le RCa était de 1,12 (0,99, 1,27). Conclusion: Un adulte canadien sur quatre était obèse. Le fait de vivre dans un milieu non urbain est un facteur de risque indépendant d'obésité. Les disparités en matière de santé entre les régions rurales et urbaines pourraient être à l'origine de ces différences, mais des recherches supplémentaires sont nécessaires.

RESUMEN

Pompe disease is a muscular dystrophy that results in respiratory insufficiency. We characterized the outcomes of targeted delivery of recombinant adeno-associated virus serotype 1 (rAAV2/1) vector to diaphragms of Pompe mice with varying stages of disease progression. We observed significant improvement in diaphragm contractile strength in mice treated at 3 months of age that is sustained at least for 1 year and enhanced contractile strength in mice treated at 9 and 21 months of age, measured 3 months post-treatment. Ventilatory parameters including tidal volume/inspiratory time ratio, minute ventilation/expired CO2 ratio, and peak inspiratory airflow were significantly improved in mice treated at 3 months and tested at 6 months. Despite early improvement, mice treated at 3 months and tested at 1 year had diminished normoxic ventilation, potentially due to attenuation of correction over time or progressive degeneration of nontargeted accessory tissues. However, for all rAAV2/1-treated mice (treated at 3, 9, and 21 months, assayed 3 months later; treated at 3 months, assayed at 1 year), minute ventilation and peak inspiratory flows were significantly improved during respiratory challenge. These results demonstrate that gel-mediated delivery of rAAV2/1 vectors can significantly augment ventilatory function at initial and late phases of disease in a model of muscular dystrophy.

RESUMEN

The end-of-life context is imbued with emotions, with death and dying transforming everyday places, like long-term care facilities, into entirely new emotional topographies that can evoke profound effects on those who live and work within these settings. Despite their significant role, healthcare providers' emotions and their interconnections with 'place' have received relatively little attention from researchers, including geographers of care and caregiving. This secondary thematic analysis attempts to address this notable gap by exploring the emotional geographies of healthcare providers caring for dying residents in four long-term care facilities in western Canada. By drawing upon interview and focus group data with administrators (n = 12) and direct care provider (n = 80) participants, findings reveal that experiences of caring for dying residents were often charged with negative emotions (e.g., distress, frustration, grief). These emotions were not only influenced by social and physical aspects of 'place', but the temporal process of caring for a dying resident, which included: (1) Identifying a resident as in need of a palliative approach to care; (2) Actively dying; and (3) Following a resident's death. Findings indicate that providers' emotions shifted in scale at each of these temporal phases, ranging from association with the facility as a whole to the micro-scale of the body. Broader structural forces that influence the physical and social place of long-term care facilities were also found to shape experiences of emotional labor among staff. With an increasing number of deaths occurring within long-term care facilities throughout the Global North, such findings contribute critical experiential knowledge that can inform policy and programs on ways to help combat staff burnout, facilitate worker satisfaction, and foster resilience among long-term care providers, ensuring they receive the necessary supports to continue fulfilling this valuable caring role.

RESUMEN

OBJECTIVES: Previous studies on depression in rural areas have yielded conflicting results. Features of rural areas may be conducive or detrimental to mental health. Our objective for this study was to determine if there are rural-urban disparities in depressive symptoms between those living in rural and urban areas of Canada. DESIGN: We conducted a cross-sectional analysis of a prospective cohort study, which is as representative as possible of the Canadian population-the Tracking Cohort of the Canadian Longitudinal Study on Aging. For this cohort, data were collected from 2010 to 2014. Data were analysed and results were obtained in 2020. PARTICIPANTS: 21 241 adults aged 45-85. MEASURES: Rurality was grouped as urban (n=11 772); peri-urban (n=2637); mixed (n=2125; postal codes with both rural and urban areas); and rural (n=4707). Depressive symptoms were measured using the 10-item Center for Epidemiological Studies-Depression. We considered age, sex, education, marital status and disease states as potential confounding factors. RESULTS: The adjusted beta coefficient was -0.24 (95% CI -0.42 to -0.07; p=0.01) for rural participants, -0.17 (95% CI -0.40 to 0.05; p=0.14) for peri-urban participants and -0.30 (95% CI -0.54 to -0.05; p=0.02) for participants in mixed regions, relative to urban regions. Risk factors associated with depressive symptoms were similar in rural and urban regions. CONCLUSIONS: The small differences in depressive symptoms among those living in rural and urban regions are unlikely to be relevant at a clinical or population level. The findings do suggest some possible approaches to reducing depressive symptoms in both rural and urban populations. Future research is needed in other settings and on change in depressive symptoms over time.

RESUMEN

OBJECTIVE: The objective is to determine the use of health-care services (physician visits, emergency department use and hospitalisations) in rural areas and examine differences in four geographic areas on a rural to urban spectrum. METHODS: We conducted a secondary analysis of cross-sectional data from a population-based prospective cohort study, the Canadian Longitudinal Study on Aging (CLSA). Participants included community-dwelling adults aged 45-85 years old from the tracking cohort of the CLSA (n = 21,241). Rurality was classified based on definitions from the CLSA sampling frame and similar to the 2006 census. Main outcome measures included self-reported family physician and specialist visits, emergency department visits and hospitalisations within the previous 12 months. Results were compared for four geographic areas on a rural-urban continuum. Univariate and bivariate analyses were performed on data from the 'tracking cohort' of the CLSA, Chi-square tests were used for categorical variables. Logistic regression models were created for the main outcome measures. RESULTS: Participants in rural and mixed rural and urban areas were less likely to have seen a family physician or a specialist physician compared to urban areas. Those living in rural and peri-urban areas were more likely to visit an emergency department compared to urban areas. These differences persisted after adjusting for sociodemographic and health-related variables. There were no significant rural-urban differences in hospitalisations. CONCLUSION: Rural-urban differences were found in visits to family physicians, specialists and emergency departments.


Objectif: Déterminer l'utilisation des services de santé (consultations chez un médecin, visites à l'urgence et hospitalisations) dans les régions rurales et examiner les différences dans 4 régions géographiques sur un spectre rural-urbain. Méthodologie: Nous avons réalisé une analyse secondaire des données transversales tirées d'une étude de cohorte prospective de population, l'étude CLSA (Canadian Longitudinal Study on Aging). La population était composée d'adultes vivant en communauté de 45 à 85 ans ayant participé à la cohorte de suivi de l'étude CLSA (N = 21 241). La ruralité était classée en fonction des définitions du cadre d'échantillonnage de l'étude CLSA et était semblable au recensement de 2006. Les principaux paramètres d'évaluation étaient les consultations rapportées par les patients chez un médecin de famille et un spécialiste, les visites à l'urgence et les hospitalisations durant les 12 mois précédents. Les résultats ont été comparés sur un continuum rural-urbain dans 4 régions géographiques. Des analyses univariées et bivariées ont été réalisées sur les données de la " cohorte de suivi " de l'étude CLSA, les tests de chi carré ont été utilisés pour les variables catégoriques. Des modèles de régression logistique ont été créés pour les principaux paramètres d'évaluation. Résultats: Les participants des régions rurales et mixtes rurales-urbaines avaient moins tendance à avoir vu un médecin de famille ou un spécialiste comparativement aux participants des régions urbaines. Les sujets des régions rurales et périurbaines avaient plus tendance à s'être rendus à l'urgence comparativement aux sujets des régions urbaines. Ces différences ont persisté après ajustement en fonction des variables sociodémographiques et liées à la santé. On n'a observé aucune différence significative des hospitalisations entre les régions rurales et urbaines. Conclusion: Des différences entre les régions rurales et urbaines ont été observées pour les consultations aux médecins de famille et aux spécialistes, et les visites à l'urgence.

RESUMEN

INTRODUCTION: Family carers are cornerstones in the care of older people living with dementia. Family carers report extensive carer burden, reduced health-related quality of life (HRQoL), and extensive time spent on informal care (Time). Health literacy (HL) is a concept associated with people's ability to access health services, and navigate the healthcare system. This study's aim was to investigate HL among family carers, and investigate the associations between HL and carer burden, HRQoL, and Time spent on informal care. METHOD: We designed a self-administered survey comprising validated instruments, including the Health Literacy Scale (HLS-N-Q12) to measure HL, Relative Stress Scale (RSS) to measure carer burden, the EQ-5D-5L instrument to measure HRQoL, and some modified questions from the Resource Utilization in Dementia (RUD) questionnaire to measure time spent on informal care (Time). Descriptive analysis in addition to bivariate and multiple linear regressions were undertaken. In multiple linear regression analysis, we used HL as the independent variable to predict the outcomes (carer burden, HRQoL, Time). Analyses were adjusted for the effects of explanatory independent variables: age, gender, education levels, urban residency, having worked as health personnel, caring for someone with severe/mild dementia, and being born abroad. FINDINGS: In a non-probability sample of 188 family carers from across Norway, most of them female and over the age of 60, we found high levels of HL. In the bivariate analysis, carer burden and HRQoL (EQvalue) showed significant associations with HL. In the multiple regression analyses, HL was statistically significantly associated with carer burden (B = -0.18 CI:-0.33,-0.02 p = 0.02), HRQoL (EQvalue: B = 0.003 with 95% CI: 0.001, 0.006 p = 0.04), and Time (B = -0.03 with 95% CI: -0.06, 0.000, p = 0.046), after adjusting for the effect of independent variables. CONCLUSION: This is one of the first studies to investigate the associations between HL and different outcomes for family carers of older people living with dementia. Additional research into the associations identified here is needed to further develop our understanding of how to support family carers in their roles. Targeted support that increases family carers' HL may have potential to enhance their ability to provide sustainable care over time.

RESUMEN

BACKGROUND: We explored the safety and efficacy of ablative doses of stereotactic body radiation therapy (SBRT) for unresectable pancreatic cancer. METHODS: This phase I/II trial included patients with unresectable pancreatic cancer previously treated with any number of cycles of induction chemotherapy. Patients were enrolled according to a 3+3 dose escalation design at 10, 12.5, and 15 Gy ×3, with subsequent patients at the maximally tolerated dose (MTD). Treatment was delivered to gross tumor delineated with MRI fusion using image-guidance to fiducial markers. Dose-limiting toxicity (DLT) was defined as grade 3+ toxicity within 30 days. Secondary endpoints included late gastrointestinal (GI) toxicity, freedom from local failure (FFLF), and survival. RESULTS: Fifteen patients received a median 10 cycles of chemotherapy. There were no DLTs, and the MTD was 15 Gy ×3. Thirty-day toxicity included grade 2 nausea (46%) and grade 2 diarrhea (7%). Median survival after SBRT was 12.8 months (23 months after diagnosis) and median relapse-free survival was 7 months. At 1-year, FFLF was 80%. Four patients had grade 3+ GI bleeding after 30 days (median 6 months). Grade 3+ GI bleeding was associated with tumor volume (P=0.01), heterogeneity of dose within the planning target volume (PTV) (V120, P=0.03), and duodenal dose (V26-30 Gy, P<0.2). CONCLUSIONS: This aggressive SBRT regimen demonstrated limited 30-day morbidity, a moderate degree of local control, and a moderate risk for late GI bleeding. Further work is necessary to define the most appropriate hypofractionated radiation therapy (RT) regimen in the ablative dose range.

RESUMEN

Multi-sectoral, interdisciplinary health research is increasingly recognizing integrated knowledge translation (iKT) as essential. It is characterized by diverse research partnerships, and iterative knowledge engagement, translation processes and democratized knowledge production. This paper reviews the methodological complexity and decision-making of a large iKT project called Seniors - Adding Life to Years (SALTY), designed to generate evidence to improve late life in long-term care (LTC) settings across Canada. We discuss our approach to iKT by reviewing iterative processes of team development and knowledge engagement within the LTC sector. We conclude with a brief discussion of the important opportunities, challenges, and implications these processes have for LTC research, and the sector more broadly.

RESUMEN

OBJECTIVE: We used latent transition analysis to explore common long-term care (LTC) service trajectories and their predictors for older adults with dementia. METHOD: Using linked administrative data collected over a 4-year interval (2008-2011), the study sample included 3,541 older persons with dementia who were clients of publicly funded LTC in British Columbia, Canada. RESULTS: Our results revealed relatively equal reliance on home care (HC) and facility-based residential care (RC) as starting points. HC service users were further differentiated into "intermittent HC" and "continuous HC" groups. Mortality was highest for the RC group. Age, changes in cognitive performance, and activities of daily living were important predictors of transitions into HC or RC. DISCUSSION: Reliance on HC and RC by persons with dementia raises critical questions about ensuring that an adequate range of services is available in local communities to support aging in place and to ensure appropriate timing for entry into institutions.
