Bud and cambial phenology represent the adaptation of species to the local environment that allows the growing season to be maximized while minimizing the risk of frost for the developing tissues. The temporal relationship between the apical and radial meristems can help in the understanding of tree growth as a whole process. The aim of this study was to compare cambial phenology in black spruce (Picea mariana (Mill.) B.S.P.) provenances classified as early and late bud flushing. The different phases of cambial phenology were assessed on wood microcores sampled weekly from April to October in 2014 and 2015 from 61 trees growing in a provenance trial in Quebec, Canada...

The geochemical behavior of ultramafic waste rocks and the effect of carbon sequestration by these waste rocks on the water drainage quality were investigated using laboratory-scale kinetic column tests on samples from the Dumont Nickel Project (RNC Minerals, QC, Canada). The test results demonstrated that atmospheric CO2 dissolution induced the weathering of serpentine and brucite within the ultramafic rocks, generating high concentrations of Mg and HCO3(-) with pH values ranging between 9 and 10 in the leachates that promote the precipitation of secondary Mg carbonates...

AIM: To identify factors associated with antidiabetic drug (AD) non-adherence among patients with type 2 diabetes and depression. STUDY DESIGN AND SETTINGS: We conducted a population-based retrospective cohort study among new AD users with a diagnosis of depression following AD initiation. We used public health insurance data from Quebec. The dependent variable was non-adherence (i.e., <90% of days covered by ≥1AD) in the year after a depression diagnosis. Different sociodemographic, clinical and medication-related variables were assessed as potential factors of non-adherence to AD treatment...

In order to promote better practices and communication around end-of-life decision-making, several Canadian hospitals in the province of Quebec have developed a tool called "Levels of Intervention" (LOI). No work to date has been published demonstrating improvement since these forms were implemented. The purpose of the present study was to obtain information about the use of LOI forms across Quebec hospitals and to identify gaps in practice as well as areas for improvement. A retrospective study was undertaken of 299 charts of patients who had died in three Quebec hospitals with a LOI ordered...

Selected human immunodeficiency virus (HIV)-infected patients with end organ failure can safely receive an organ transplant from an HIV uninfected donor. Recent demonstration of the short term safety of organ transplantation between HIV-infected persons prompted a change in US American law to allow such transplantations. Prompted by the recent completion of the first organ transplantation between HIV-infected persons in Canada, we review Canadian law regarding the use of organs from HIV-infected donors, estimate the number of potential HIV-infected donors in Canada, and critically review considerations related to advancing organ transplantation from HIV-infected donors in Canada...

BACKGROUND: Patient decision aids (PtDAs) help people make difficult, values-sensitive decisions. Prenatal screening for assessing the risk of genetic conditions in the fetus is one such decision and patient decision aids are rarely used in this clinical context. We sought to identify factors influencing pregnant women's use of a patient decision aid for deciding about prenatal screening for Down syndrome (DS). METHODS: This qualitative study was embedded in a sequential mixed-methods research program whose main aim is to implement shared decision-making (SDM) in the context of prenatal screening for DS in the province of Quebec, Canada...

Quebec Platelet disorder (QPD) is a unique bleeding disorder that markedly increases urokinase plasminogen activator (uPA) in megakaryocytes and platelets but not in plasma or urine. The cause is tandem duplication of a 78 kb region of chromosome 10 containing PLAU (the uPA gene) and C10orf55, a gene of unknown function. QPD increases uPA in platelets and megakaryocytes >100 fold, far more than expected for a gene duplication. To investigate the tissue-specific effect that PLAU duplication has on gene expression and transcript structure in QPD, we tested if QPD leads to: 1) overexpression of normal or unique PLAU transcripts; 2) increased uPA in leukocytes; 3) altered levels of C10orf55 mRNA and/or protein in megakaryocytes and leukocytes; and 4) global changes in megakaryocyte gene expression...

BACKGROUND: During a major outbreak of West Nile virus (WNV) infection in the province of Quebec in 2012, public health authorities (PHAs) suspected underrecognition of West Nile neurologic disease (WNND). With data on acute infections detected in blood donors, an estimate of the degree of underrecognition was produced. STUDY DESIGN AND METHODS: All 2012 donors were tested for WNV infection with the use of reverse transcription-polymerase chain reaction (RT-PCR)...

INTRODUCTION: ePortfolios are frequently used to support continuing professional development (CPD) of rehabilitation professionals. Though this tool is now widely implemented in many professions by regulatory organisations, very few studies have investigated the use and impact among rehabilitation professionals. Implementation of comprehensive ePortfolios that are centred on the needs of rehabilitation professionals requires documenting their level of use and perceived outcomes. OBJECTIVES: The objectives were to describe how occupational therapists use a mandatory ePortfolio that has been recently implemented by a regulatory organisation in Quebec (Canada) and the perceived outcomes of this requirement on continuing professional development and practice change...

Urbanization is one of the major anthropogenic processes contributing to local habitat loss and extirpation of numerous species, including wild bees, the most widespread pollinators. Little is known about the mechanisms through which urbanization impacts wild bee communities, or the types of urban green spaces that best promote their conservation in cities. The main objective of this study was to describe and compare wild bee community diversity, structure, and dynamics in two Canadian cities, Montreal and Quebec City...

BACKGROUND: Long-standing concern exists over hospital use by people near or at the end of life (EOL) related to the appropriateness, quality, and cost of care in hospital. It is widely believed that most people die in hospital after an escalation in hospital use over the last year of life. As most deaths in high-income countries are not sudden or unexpected, opportunities exist for planning compassionate, effective, and evidence-based EOL care. OBJECTIVE: Gain current population-based evidence for EOL health policy and services planning...

BACKGROUND: Only few medicines are licensed for children. The use of emerging drugs (unmarketed drug, off-label drug with poorly documented use, and/or costly drugs) might represent an essential alternative for pediatric patients. OBJECTIVES: The objective of the study was to assess emerging drug uses rate and profile in our women's and children's centre to support the implementation of an appropriate policy. METHODS: We identified retrospectively emerging drugs used between 2013-01-01 and 2014-02-28, using computerized pharmacist software extraction of drugs used...

The Quebec Pain Registry (QPR) is a large research database of patients suffering from various chronic pain (CP) syndromes who were referred to one of five tertiary care centres in the province of Quebec (Canada). Patients were monitored using common demographics, identical clinical descriptors, and uniform validated outcomes. This paper describes the development, implementation, and research potential of the QPR. Between 2008 and 2013, 6902 patients were enrolled in the QPR, and data were collected prior to their first visit at the pain clinic and six months later...

The pathways model of problem gambling suggests the existence of three developmental pathways to problem gambling, each differentiated by a set of predisposing biopsychosocial characteristics: behaviorally conditioned (BC), emotionally vulnerable (EV), and biologically vulnerable (BV) gamblers. This study examined the empirical validity of the Pathways Model among adolescents followed up to early adulthood. A prospective-longitudinal design was used, thus overcoming limitations of past studies that used concurrent or retrospective designs...

BACKGROUND: Inuit interpreters are key players in end-of-life (EOL) care for Nunavik patients and families. This emotionally intensive work requires expertise in French, English and Inuit dialects to negotiate linguistic and cultural challenges. Cultural differences among medical institutions and Inuit communities can lead to value conflicts and moral dilemmas as interpreters navigate how best to transmit messages of care at EOL. OBJECTIVES: Our goal was to understand the experience of Inuit interpreters in the context of EOL care in Nunavik in order to identify training needs...
