Past studies have identified various risk and protective factors for problem gambling (PG). However, no study has examined the interplay between these factors using a combination of person-centered and variable-centered approaches embedded within a longitudinal design. The present study aimed to (a) identify distinct profiles in early adolescence based on a set of risk factors commonly associated with PG (impulsivity, depression, anxiety, drug-alcohol use, aggressiveness, and antisociality), (b) explore the difference in reported gambling problems between these profiles during midadolescence and early adulthood, and (c) identify family- and peer-related variables that could operate as protective or compensatory factors in this context...

Background: Serious violent acts (e.g. physical violence, robbery, sexual aggression and death threats) are among the most visible and notable examples of workplace violence. Although women are commonly found to be at higher risk for post-traumatic reactions following workplace violence, little is known as regards sex differences concerning the types of post-traumatic reactions and their predictors. Objective: This study aimed to describe sex differences in the post-traumatic reactions of serious violent acts and the predictors of such reactions...

The Northern Biodiversity Paradox predicts that, despite its globally negative effects on biodiversity, climate change will increase biodiversity in northern regions where many species are limited by low temperatures. We assessed the potential impacts of climate change on the biodiversity of a northern network of 1,749 protected areas spread over >600,000 km2 in Quebec, Canada. Using ecological niche modeling, we calculated potential changes in the probability of occurrence of 529 species to evaluate the potential impacts of climate change on (1) species gain, loss, turnover, and richness in protected areas, (2) representativity of protected areas, and (3) extent of species ranges located in protected areas...

BACKGROUND: Adolescents in a dating relationship can interact anytime using information and communication technologies. Yet, despite associated potential benefits, this availability of means to reach out to their partner may also exacerbate possible conflictual exchanges, including dating violence through technology. This study aimed to document the prevalence of cyber dating violence (CDV) victimization and perpetration among teenagers. It also explored self-esteem and psychological distress in participants having been perpetrators, victims, or perpetrator-victims, compared with those not having experienced CDV...

BACKGROUND: Over- and under-coagulation with warfarin is associated with hemorrhagic and thromboembolic events, respectively. Genetic and clinical factors affect warfarin response, and the causes of this variability remain unclear. We present descriptive statistics and test for predictors of poor anticoagulation control. METHODS: The Quebec Warfarin Cohort (QWC) comprises 1,059 new warfarin users, with prospective follow up using telephone questionnaires every 3 months for one year, and using healthcare administrative databases (RAMQ and Med-Echo) for 5-year prior to cohort entry and up to 10-years following active patient participation...

Lotteries are one of the most prevalent forms of gambling and generate substantial state revenues. They are also argued to be one of the least harmful forms of gambling. This paper is one of the first to examine exclusive lottery gamblers and compares their gambling patterns and problems as well other associated risky behaviours to those who are not exclusive lottery gamblers. Data were derived from two large surveys conducted with representative adult samples in France (n = 15,635) and Québec (n = 23,896)...

BACKGROUND: Screening colonoscopy for the detection of colorectal carcinoma is provided by several specialties. Few studies have assessed geographic variation in the delivery of this care. Our objective was to investigate how geographic and socioeconomic factors affect who provides screening colonoscopy in Canada. METHODS: This was a population-based cohort of all screening colonoscopy procedures performed at publicly funded Canadian health care facilities (excluding those in Quebec) between April 2008 and March 2015...

Plasma triglyceride concentrations are normally below 150 mg/dL in the fasting state. However, these lipids can reach values of several thousand mg/dL. Elevations in this range are due to a massive retention of chylomicrons and usually result from multiple genetic variants with superimposed influences such as diabetes and immune disorders. Less commonly, major gene defects in lipoprotein metabolism can be the cause. These may present soon after birth with strong evidence of familial penetrance. The causes of this syndrome have been discussed in a Roundtable published in the most recent issue of this Journal...

BACKGROUND: The accessibility of laboratory test results is crucial to the performance of emergency departments and to the safety of patients. This study aims to develop a better understanding of which laboratory information exchange (LIE) systems emergency care physicians (ECPs) are using to consult their patients' laboratory test results and which benefits they derive from such use. METHODS: A survey of 163 (36%) ECPs in Quebec was conducted in collaboration with the Quebec's Department of Health and Social Services...

Due to climate change, the ranges of many North American tree species are expected to shift northward. Sugar maple ( Acer saccharum Marshall) reaches its northern continuous distributional limit in northeastern North America at the transition between boreal mixed-wood and temperate deciduous forests. We hypothesized that marginal fragmented northern populations from the boreal mixed wood would have a distinct pattern of genetic structure and diversity. We analyzed variation at 18 microsatellite loci from 23 populations distributed along three latitudinal transects (west, central, and east) that encompass the continuous-discontinuous species range...

BACKGROUND: Bone metastases represent the most frequent cause of cancer-related pain, affecting health-related quality of life and creating a substantial burden on the healthcare system. Although most bony metastatic lesions can be managed nonoperatively, surgical management can help patients reduce severe pain, avoid impending fracture, and stabilize pathologic fractures. Studies have demonstrated functional improvement postoperatively as early as 6 weeks, but little data exist on the temporal progress of these improvements or on the changes in quality of life over time as a result of surgical intervention...

Salmonella enterica serovar Heidelberg (S. Heidelberg) is one of the top serovars causing human salmonellosis. This serovar ranks second and third among serovars that cause human infections in Québec and Canada, respectively, and has been associated with severe infections. Traditional typing methods such as PFGE do not display adequate discrimination required to resolve outbreak investigations due to the low level of genetic diversity of isolates belonging to this serovar. This study evaluates the ability of four whole genome sequence (WGS)-based typing methods to differentiate among 145 S...

PURPOSE: We examined the prospective influence of early child problematic behavior on later coercive interactions and binge drinking by mothers. DESIGN AND METHODS: Canadian participants are from the Quebec Longitudinal Study of Child Development, born between spring 1997 and 1998, which allowed a longitudinal birth cohort design. At the 41months, 628 parents reported on children's oppositional, aggressive, turbulent, and inattentive/hyperactive behavior. Mothers then reported on their own coercive and binge drinking behavior at the 60month follow-up...

In Canada, over 40% of invasive cervical cancers occur among women who have never been screened. Although 12% of Canadian women have never been screened, this number can be as high as 43% among certain social groups. Little is published on factors associated with screening uptake and inequalities among women residing in Quebec. Four waves of the Canadian Community Health Survey (2003, 2005, 2008, 2012, N = 6393) were utilized to assess lifetime screening and screening in the previous 3 years among women residing in Montreal...

BACKGROUND: Frequent users of healthcare services are a vulnerable population that deserves attention due to high costs and negative outcomes such as lower quality of life and higher mortality. Healthcare systems should offer interventions tailored to their needs and to their level of health literacy, including strategies to promote activation. The relationship between health literacy and patient activation remains to be explored. The aim of this study was to examine the association between health literacy and patient activation in a population of frequent users of healthcare services with chronic diseases...

Lyme disease is an emerging public health threat in Canada. In this context, rapid detection of new risk areas is essential for timely application of prevention and control measures. In Canada, information on Lyme disease risk is collected through three surveillance activities: active tick surveillance, passive tick surveillance, and reported human cases. However, each method has shortcomings that limit its ability to rapidly and reliably identify new risk areas. We investigated the relationships between risk signals provided by human cases, passive and active tick surveillance to assess the performance of tick surveillance for early detection of emerging risk areas...

BACKGROUND: Non-vitamin K antagonist oral anticoagulants (NOACs) are relatively new drugs used for stroke prevention in nonvalvular atrial fibrillation (NVAF). However, there are concerns that their use may be associated with hepatotoxic effects. OBJECTIVES: The purpose of this study was to determine whether the use of NOACs is associated with an increased risk of serious liver injury compared with the use of vitamin K antagonists (VKAs) in NVAF patients with and without prior liver disease...
