INTRODUCTION: Previous studies have shown that French-speaking family physicians (FSPs) in Ontario are less numerous in areas with high proportions of francophones. The purpose of the current study was to assess whether the degree of concordance between physicians' language of competence and the linguistic profile of the community in which they practise is associated with workload and to explore variations in this relation in rural and northern regions of the province. METHODS: This was a secondary analysis of the 2013 College of Physicians and Surgeons of Ontario Annual Membership Renewal Survey...

Water level (WL) fluctuations in lakes influence many aspects of ecosystem processes. Concern about the potential impact of WL fluctuations on fisheries was one of the factors that motivated the decision in 2000 to alter the management of WL in the Rainy-Namakan reservoir complex (on the border between the U.S. state of Minnesota and the Canadian province of Ontario). We used a Before-After, Control-Impact (BACI) framework to identify potential impacts of the change in WL management to Walleye, Northern Pike and Yellow Perch catch per unit effort (CPUE)...

In the US, rabies virus (RV) has been enzootic in raccoons ( Procyon lotor) since the late 1940s. Oral rabies vaccination (ORV) was implemented in the 1990s to halt the spread of raccoon RV and continues to be used as a wildlife management tool. Our objective was to evaluate a recombinant human adenovirus-rabies virus glycoprotein vaccine in northern New York, Vermont, and New Hampshire over a 3-yr period, using changes in RV neutralizing antibody (RVNA) seroprevalence in raccoon populations as an immunologic index of ORV impact...

The use of species distribution as a climate proxy for ecological forecasting is thought to be acceptable for invasive species. Kudzu (Pueraria montana var. lobata) is an important invasive whose northern distribution appears to be limited by winter survival; however, kudzu's cold tolerance thresholds are uncertain. Here, we used biogeographic evidence to hypothesize that exposure to - 20 °C is lethal for kudzu and thus determines its northern distribution limit. We evaluated this hypothesis using survival tests and electrolyte leakage to determine relative conductivity, a measure of cell damage, on 14 populations from eastern North America...

Aqueous natural organic matter (NOM) contains different types of functional groups (carboxylic, phenolic, sulfidic, etc.), and hence could change the speciation of metals in environmental systems. This work is a proof-of-concept study on the interaction of three metals (Cu, Co, and Cs) with NOM using fluorescence spectroscopy. The specific aim was to determine the conditional stability constants for these three metals with NOM optical components, obtained from the quenching of fluorescence signals. Three contrasting water types were sampled in Northern Ontario: a pristine source (Cross Rd...

INTRODUCTION: Nursing stations are the only access point into the health care system for some communities and have limited capabilities and resources. We describe characteristics of patients injured in Northern Ontario who present to nursing stations and require transport by air ambulance. Secondary objectives are to compare interventions performed at nursing stations with those performed by flight paramedics and to identify systemic gaps in trauma care. METHODS: A retrospective cohort study was performed of all injured patients transported by air ambulance from April 1, 2014, to March 31, 2015...

Rural patients with opioid use disorder (OUD) face a variety of barriers when accessing opioid agonist therapy (OAT) and psychiatric services, due to the limited supply of physicians and the vast geographic area. The telemedicine allows for contact between patients and their physician-regardless of physical distance. Objective . We characterize the usage of telemedicine to deliver psychiatric services to patients with OUD in Ontario, as well as traits of treatment-seeking patients with opioid dependence and concurrent psychiatric disorders...

RATIONALE: Self-management programs are an established approach to helping people cope with the challenges of chronic disease, but the psychological mechanisms underlying their effectiveness are not fully understood. A key assumption of self-management interventions is that enhancing people's self-efficacy (e.g., via the development of relevant skills and behaviours) encourages adaptive health-related behaviors and improved health outcomes. However, the group-based nature of the programs allows for the possibility that identification with other program members is itself a social psychological platform for positive changes in illness-related confidence (i...

Although many studies have reported mechanisms of resistance to metals in herbaceous species, there is very little information on metal coping strategy in hardwood species such as Quercus rubra. The main objective of this study was to determine the expression of genes associated with nickel resistance in red oak (Q. rubra) populations from metal contaminated and uncontaminated sites in the Northern Ontario. Six genes associated with nickel resistances in model and non-model plants were targeted. Differential expressions of these genes were observed in Q...

BACKGROUND: Lyme disease (LD) is a bacterial infection transmitted by the black-legged tick (Ixodes scapularis) in eastern North America. It is an emerging disease in Canada due to the expanding range of its tick vector. Environmental risk maps for LD, based on the distribution of the black-legged tick, have focused on coarse determinants such as climate. However, climatic factors vary little within individual health units, the level at which local public health decision-making takes place...

INTRODUCTION: Health education about Indigenous populations in Canada (First Nations, Inuit, and Métis people) is one approach to enable health services to mitigate health disparities faced by Indigenous peoples related to a history of colonization and ongoing social inequities. This evaluation of a continuing medical education workshop, to enhance family physicians' clinical approach by including social and cultural dimensions within diabetes management, was conducted to determine whether participation in the workshop improved self-reported knowledge, skills, and confidence in working with Indigenous patients with type 2 diabetes...

Northwestern Ontario, Canada, is a large, sparsely populated geographic area with many small rural and remote communities. Most health services are delivered by primary care generalists. The goal of the North West LHIN Regional Palliative Care Program (RPCP) with St. Joseph's Care Group is to create an integrated system of palliative care accessible to all individuals in Northwestern Ontario who would benefit from a palliative approach, regardless of location, prognosis, or diagnosis. To achieve this goal and increase access to palliative care at the primary care level, the RPCP has used the Kelley Community Capacity Development Model to guide their process of developing palliative care programs in 8 different rural communities...

BACKGROUND: Despite evidence for effective fall prevention interventions, measurable reductions in older adult (≥ 65 years) fall rates remain unrealized. This study aimed to describe the perceived barriers to and effective strategies for the implementation of evidence-based fall prevention practices within and across diverse community organizations. This study is unique in that it included community service providers who are not generally thought to provide fall prevention services to older adults, such as retail business, community support, volunteer services, community foundations, recreation centres, and various emergency services...

Restricted fish consumption due to elevated contaminant levels may limit the intake of essential omega-3 fatty acids, such as eicosapentaenoic (EPA; 20:5n-3) and docosahexaenoic (DHA; 22:6n-3) acids. We analyzed lake- and length-specific mercury and EPA+DHA contents in Walleye (Sander vitreus; Mitchell 1818) from 20 waterbodies in Ontario, Canada, and used this information to calculate the theoretical intake of EPA+DHA when the consumption advisories are followed. The stringent consumption advisory resulted in decreased EPA+DHA intake regardless of the EPA+DHA content in Walleye...

Mercury (Hg) levels in Ontario top predator fishes have been increasing in recent decades. These increases may be a result of many additive factors, including global climate change. Only recently has research been conducted on how climate change may impact Hg levels in freshwater fishes at large-scales. We examined the relationship between Hg trends and (1) local weather, (2) large-scale climate drivers, and (3) anthropogenic Hg emissions, in native cool water (walleye and northern pike) and warm water (smallmouth bass and largemouth bass) predatory fishes in Ontario, Canada, for historical (1970-1992) and recent (1993-2014) time periods...

We examined the degree of exposure of lead (Pb), mercury (Hg), and several organohalogen contaminants and its potential impact on survival of bald eagles in Ontario from 1991 to 2008. Overall, results for 43 dead or dying bald eagles collected in the province indicate that 23% (10/43) of birds died of Pb poisoning and 9% (4/43) died of suspected Hg poisoning. Pb poisoning was diagnosed based on exceedances of toxicity thresholds in liver and kidney and supported by clinical observations, necropsy results, and histology findings when available...
