BACKGROUND: In North America, the last ice age is the most recent event with severe consequences on boreal species' ranges. Phylogeographic patterns of range expansion in trembling aspen (Populus tremuloides) suggested that Beringia is likely to be a refugium and the "ice-free corridor" in Alberta may represent a region where small populations persisted during the last glacial maximum (LGM). The purpose of this study was to ascertain whether the origins of trembling aspen in western North America are reflected in the patterns of neutral genetic diversity and population structure...

BACKGROUND: Falls are the leading cause of injury-related hospital admissions in Canadian older adults, accounting for 85 % of injury hospitalizations among older adults aged over 65 years. While many of these injuries can lead to death, the survival rates of fall-related injuries are rarely examined. This surveillance study examined the fall injury hospitalization and survival rates among older adults in the context of place. METHODS: Saskatchewan's health administrative data on injury hospitalizations among individuals aged 65 years and over (n = 39,867) was utilized for this study...

INTRODUCTION: Suicide is disproportionately common among Aboriginal people in Canada. METHODS: Life stories were collected from 54 Aboriginal suicide attempters in northern Saskatchewan. Constant comparison techniques and modified grounded theory identified common themes expressed. RESULTS: Three common plots/themes preceded suicide attempts: 1) relationship breakup, usually sudden, unanticipated, involving a third person; 2) being publicly humiliated by another person(s), accompanied by high levels of shame; and 3) high levels of unremitting, chronic life stress (including poverty) with relative isolation...

While the prevalence of infectious bursal disease virus (IBDV) on chicken farms in some provinces of Canada has been documented, the economic impact of variant IBDV infection on the broiler chicken industry in Saskatchewan has not. The objectives of this study were to identify the variant strains of IBDV circulating on Saskatchewan chicken farms and evaluate their economic impact on broiler production. Infection due to IBDV was detected in 43% of Saskatchewan chicken farms, with variant strains detected in infected birds closely related predominantly to NC171, 586, and Delaware-E...

BACKGROUND: A patient's trajectory through the healthcare system affects resource use and outcomes. Data fields in population-based administrative health databases are potentially valuable resources for constructing care trajectories for entire populations, provided they can capture patient transitions between healthcare services. This study describes patient transitions from the emergency department (ED) to other healthcare settings, and ascertains whether the discharge disposition field recorded in the ED data was a reliable source of patient transition information from the emergency to the acute care settings...

The transmission and prevalence of Human Immunodeficiency Virus (HIV) among those employed as sex trade workers (STW) is a major public health concern. The present study describes the self-reported responses of 340 STW, at-risk for contracting HIV. The participants were recruited by selective targeting between 2009 and 2010 from within the Saskatoon Health Region (SHR), Saskatchewan, Canada. As of 2012, the SHR has the highest incidence rate of positive test reports for HIV in Canada, at more than three times the national average (17...

STUDY OBJECTIVE: To test a brief intervention for preventing statin nonadherence among community pharmacy patrons. DESIGN: Prospective, cluster-randomized, controlled trial (the Community Pharmacists Assisting in Total Cardiovascular Health [CPATCH] trial). SETTING: Thirty community pharmacies in Saskatchewan, Canada. PATIENTS: Participating pharmacies were randomized to 15 intervention pharmacies where a brief statin adherence intervention was delivered by pharmacists (intervention group [907 patients]) or 15 usual care pharmacies where no statin adherence intervention was delivered (usual care group [999 patients]) to new users of statins (defined as less than 1 yr of statin therapy)...

To determine the predictors of cognitive decline in a rural and remote population with Alzheimer's disease (AD), we examined the association between cognitive change and sociodemographic, clinical, and functional data at the initial day of diagnosis. Simple linear regression analysis and multiple regression analysis were used to determine the predictors of cognitive decline as measured by the difference in the Mini-Mental State Examination over 1 year. Our sample included 72 patients with AD. Age at the clinic day appointment was 75...

Background: Whether vaccinating children with intranasal live attenuated influenza vaccine (LAIV) is more effective than inactivated influenza vaccine (IIV) in providing both direct protection in vaccinated persons and herd protection in unvaccinated persons is uncertain. Hutterite colonies, where members live in close-knit, small rural communities in which influenza virus infection regularly occurs, offer an opportunity to address this question. Objective: To determine whether vaccinating children and adolescents with LAIV provides better community protection than IIV...

Few workplaces have prospectively reviewed workplace and worker issues simultaneously and assessed their impact on Workers' Compensation Board (WCB) claims. In January of 2014, each worker in a large workplace in Saskatchewan, Canada, was prospectively followed for 1 year to determine factors that impact injury claim incidence, recovery, and costs. In total, 207 out of 245 workers agreed to complete the baseline survey (84.5%). In 2014, 82.5% of workers had self-reported pain, but only 35.5% submitted a WCB claim...

The prevalence of being overweight during childhood continues to increase in the USA and Canada and children living in rural areas are more at risk than their urban counterparts. The objectives of this study were to evaluate how well the parent's perception of their child's weight status correlated with objectively measured weight status among a group of rural children and to identify predictors of inaccurate parental perceptions of child's weight status. Participants were children from the Saskatchewan Rural Health Study conducted in 2010...

Johne's disease is a worldwide concern, as it causes huge economic losses. The etiological agent, Mycobacterium avium ssp. paratuberculosis (MAP), has limited genetic diversity, impeding efforts to understand transmission and distribution of strain types. Whole-genome sequencing was previously performed on a representative set of MAP isolates from Canadian dairy herds and 9 divergent clades were identified. Four clades were of particular interest, as they were either MAP types rarely reported in North America, or they represented a substantial proportion of isolates recovered from dairy farms in Canada...

Life cycle greenhouse gas (GHG) emissions from the production of nuclear power (in g CO2e/kWh) are uncertain due partly to a paucity of data on emissions from individual phases of the nuclear fuel cycle. Here, we present the first comprehensive life cycle assessment of GHG emissions produced from the mining and milling of uranium in Canada. The study includes data from 2006-2013 for two uranium mine-mill operations in northern Saskatchewan (SK) and data from 1995-2010 for a third SK mine-mill operation. The mine-mill operations were determined to have GHG emissions intensities of 81, 64, and 34 kg CO2e/kg U3O8 at average ore grades of 0...
