Background and Aims: Knowledge of thermal acclimation of physiological processes of boreal tree species is necessary to determine their ability to adapt to predicted global warming and reduce the uncertainty around the anticipated feedbacks of forest ecosystems and global carbon cycle to climate change. The objective of this work was to examine the extent of thermal acclimation of net photosynthesis (An) and dark respiration (Rd) of two distant white spruce (Picea glauca) seed sources (from south and north of the commerial forest zone in Québec) in response to latitudinal and seasonal variations in growing conditions...

Gender-based violence (GBV) is a global epidemic associated with increased HIV exposure. We assessed the prevalence and correlates of HIV acquisition via forced sex among women living with HIV (WLWH) in Canada. Baseline questionnaire data were analyzed for WLWH (≥16 years) with data on self-reported mode of HIV acquisition, enrolled in a community-based cohort study in British Columbia, Ontario, and Québec. We assessed forced sex (childhood, adulthood) as a self-reported mode of HIV acquisition. Of 1,330 participants, the median age was 42 (interquartile range [IQR] = 35-50) years; 23...

BACKGROUND: Hospitalizations for ambulatory care sensitive conditions (ACSCs) are potentially preventable, but may be required if these conditions are not managed well. National-level information about ACSC hospitalizations is available for Canada, but not for Aboriginal groups. This study describes ACSC hospitalizations among urban Métis adults relative to their non-Aboriginal counterparts. DATA AND METHODS: The 2006/2007-to-2008/2009 Discharge Abstract Database, which contains hospitalization records from all acute care facilities (excluding Quebec), was linked to the 2006 Census to obtain Aboriginal identity information...

OBJECTIVES: Leflunomide is known to be embryotoxic and teratogenic in rodents. However, there is less evidence in humans. We quantified the risk of major congenital malformation (MCM), prematurity, low birth weight (LBW) and spontaneous abortion associated with leflunomide exposure during pregnancy in humans. METHODS: From a cohort of 289 688 pregnancies in Montreal, Quebec, Canada, from 1998 to 2015, first-trimester leflunomide exposure and other antirheumatic drug exposures were studied for their association with MCM and spontaneous abortions...

In democratic societies, good governance is the key to assuring the confidence of stakeholders and other citizens in how governments and organizations interact with and relate to them and how decisions are taken. Although defining good governance can be debatable, the United Nations Development Program (UNDP) set of principles is commonly used. The reimbursement recommendation processes of the Canadian Agency for Drugs and Technologies in Health (CADTH), which carries out assessments for all public drug plans outside Quebec, are examined in the light of the UNDP governance principles and compared with the National Institute for Health and Care Excellence system in England...

Euthanasia was decriminalized in Quebec in December 2015, and Canada-wide in June 2016. Both the Provincial and Federal legislation have limited the right to medical assistance in dying (MAID) to end-of-life cases; which makes MAID inaccessible to most patients solely suffering from psychiatric illness. While some end-stage anorexia nervosa or elderly patients may meet the end-of-life criterion because of their medical comorbidities or their age (Kelly et al., 2003), repeated suicide attempts or psychotic disorganization would not qualify since they would not be seen as elements of an illness leading to a foreseeable "natural death" (Canada, 2016)...

The extra-label use of ceftiofur in Canadian hatcheries was cause for concern due to an increased prevalence of ceftiofur resistant Salmonella Heidelberg in chickens and humans in Québec. Due to on-going concerns related to human health the use of ceftiofur was eventually phased out of the poultry production industry in 2014-2015. Simultaneous resistance to amoxicillin-clavulanic acid, ceftiofur and cefoxitin, a pattern known as A2C, caused by the presence of blaCMY-2 has become increasingly prevalent in broiler flocks worldwide...

Cigarette use and binge drinking are risky behaviors emerging during adolescence. Although many beneficial factors are well documented, studies linking shyness to substance use are somehow conflicting, which may be due to the contribution of moderators. Therefore, the present study has 2 objectives: (a) to prospectively analyze the association between shyness and substance use during adolescence, and (b) to test the moderating role of peer group affiliation on the relationship between shyness and substance use...

The conjoint association of gestational diabetes mellitus (GDM) and gestational hypertension (GH) with cardiometabolic disease has not been well studied. We evaluated a combined GDM/GH risk indicator in both mothers and fathers because of shared spousal behaviors and environments. In the present population-based retrospective cohort study, GH was identified in matched pairs of mothers with GDM or without GDM (matched on age group, health region, and year of delivery) who had singleton live births in Quebec, Canada (1990-2007)...

INTRODUCTION: Outdoor heat increases the risk of preterm birth and stillbirth, but the association with placental abruption has not been studied. Placental abruption is a medical emergency associated with major morbidity and mortality in pregnancy. We determined the relationship between ambient temperature and risk of placental abruption in warm seasons. MATERIAL AND METHODS: We performed a case-crossover analysis of 17,172 women whose pregnancies were complicated by placental abruption in Quebec, Canada from May to October 1989-2012...

OBJECTIVES: Socioeconomic position (SEP) is inversely associated with most oral health outcomes, but the patterns of association may vary depending on the specific outcome. We estimated associations between SEP and two oral health outcomes, dental caries and traumatic dental injuries (TDI), in Quebec children. METHODS: We used data from the baseline visit of the QUALITY (QUebec Adipose and Lifestyle Investigation in Youth) Cohort, an ongoing study in Montreal and Quebec, Canada...

BACKGROUND: Naloxone is life-saving when administered after opioid overdose. In March 2016, the Canadian government made the antidote available without prescription, but anecdotal reports suggest members of the public have difficulty in procuring it. We examined the availability of naloxone in community pharmacies across Canada. METHODS: We identified community pharmacies in Canada (n = 10 296) and randomly selected 506, stratified using proportionate allocation by population size...

BACKGROUND: The pan-Canadian Oncology Drug Review (pcodr) was implemented in 2011 to address uneven drug coverage and lack of transparency with respect to the various provincial cancer drug review processes in Canada. We evaluated the impact of the pcodr on provincial decision concordance and time from Notice of Compliance (noc) to drug funding. METHODS: In a retrospective review, Health Canada's Drug Product Database was used to identify new indications for cancer drugs between January 2003 and May 2014, and provincial formulary listings for drug-funding dates and decisions between 1 January 2003 and 31 December 2014 were retrieved...

RATIONALE: The prevalence of musculoskeletal disorders is high and expected to increase in the next decade. Persons suffering from musculoskeletal disorders benefit from early physiotherapy services. However, access to publicly funded physiotherapy services has been shown to be compromised by long waiting times and limited availability of resources in many countries around the world. Decisions on resource allocation may create geographic disparities in provision and access to services, which may result in inequity in access...

Background: We sought to determine if immune disorders early in life were associated with the later risk of Guillain-Barré syndrome, a neurological disorder thought to be infection-related. Methods: We conducted a longitudinal cohort study with 16 108 819 person-years of follow-up for a population of 1 108 541 parous women in Quebec, Canada (1989-2014). The outcome was Guillain-Barré syndrome. We identified women with potential risk factors for future Guillain-Barré syndrome, including immune-mediated and rheumatological diseases, cancer, transfusion, surgical procedures and pregnancy-specific disorders...

BACKGROUND: A large measles outbreak occurred in Quebec, Canada, in 2011. Although nearly two-thirds of the cases occurred in only two health districts, a mass vaccination campaign targeting all Quebec elementary and high school students without valid two-dose history was undertaken to prevent future outbreaks. We compared rates of non-vaccination and age at first measles vaccine dose among students in the two most-affected districts and the rest of the province and estimated the improvement in overall student measles immunity due to the mass school-based vaccination campaign...

The reduction of competition through thinning increases radial growth in the stem and roots of many conifer species. However, not much is known about the effect of thinning on the dynamics of wood formation and intra-annual development of the growth ring, especially in the roots, which are an essential part of the tree for stability and resource acquisition. The aim of this study was to evaluate the effect of an experimental thinning on the dynamics and phenology of xylogenesis in the stem and roots of black spruce and balsam fir...

Healthcare system reforms are pushing beyond primary care to more holistic, integrated models of community based primary health care (CBPHC) to better meet the needs of aging populations and their carers. Across the world CBPHC is at varying stages of evolution and no standard model exists. In order to scale up and spread successful models of care it is important to study what works well and why to support broader efforts to implement, scale-up and spread promising innovations. The first step in this endevour is to select appropriate cases to study...
