OBJECTIVE: The Clock Drawing Test (CDT) is frequently used to screen for cognitive impairment, however, normative data for Rouleau et al.'s scoring system are scarce. The present study aims to provide norms for Rouleau et al.'s scoring system that are tailored to Quebec French-speaking mid- and older aged healthy adults. METHODS: Six researchers from various research centers across the Province of Quebec (Canada) sent anonymous data for 593 (391 women) healthy community-dwelling volunteers (age range: 43-93 years; education range: 5-23 years) who completed the CDT 'drawing on command' version...

CONTEXT: - In the early 1900s, it was common practice to retain, prepare, and display instructive pathologic specimens to teach pathology to medical trainees and practitioners; these collections were called medical museums. Maude Abbott established her reputation by developing expertise in all aspects of medical museum work. She was a founder of the International Association of Medical Museums (later renamed the International Academy of Pathology) and became an internationally renowned expert on congenital heart disease...

A railway accident which occurred in Lac-Megantic in Quebec, Canada, caused disruption for an entire community. This study examines the psychosocial difficulties in a group of exposed adolescents aged between 11 to 17, nine months after the tragedy. The analyses were conducted on a sample of 515 adolescents, attending high school, and living near the impact area. Post-traumatic stress disorder (PTSD), mental health problems (depression, anxiety), and problem use of alcohol or drugs prevalence were estimated...

OBJECTIVE: The Trail Making Test (TMT) is mainly used to assess visual scanning/processing speed (part A) and executive functions (part B). The test has proven sensitive at detecting cognitive impairment during aging. However, previous studies have shown differences between normative data from different countries and cultures, even when corrected for age and education. Such inconsistencies between normative data may lead to serious diagnostic errors, thus, the development of local norms is warranted...

Objective: Physicians commonly prescribe antidepressants for indications other than depression that are not evidence-based and need further evaluation. However, lack of routinely documented treatment indications for medications in administrative and medical databases creates a major barrier to evaluating antidepressant use for indications besides depression. Thus, the aim of this study was to derive a model to predict when primary care physicians prescribe antidepressants for indications other than depression and to identify important determinants of this prescribing practice...

Knowledge of the quantity and the type of residual household waste (RHW) generated by a population within a given territory is essential for developing affordable, effective, and sustainable management strategies for waste. This study aims to accurately describe the composition of residential residual materials collected directly from households over the course of a year. Household waste was collected from urban and rural sectors that were representative of the study territory. Samples were collected during the winter, summer, and fall of 2014...

BACKGROUND: The risk of contracting Lyme disease (LD) can vary spatially because of spatial heterogeneity in risk factors such as social-behavior and exposure to ecological risk factors. Integrating these risk factors to inform decision-making should therefore increase the effectiveness of mitigation interventions. OBJECTIVES: The objective of this study was to develop an integrated social-behavioral and ecological risk-mapping approach to identify priority areas for LD interventions...

Compared with mice, adult rats living at 3,600 m above sea level (SL-La Paz, Bolivia) have high hematocrit, signs of pulmonary hypertension, and low lung volume with reduced alveolar surface area. This phenotype is associated with chronic mountain sickness in humans living at high altitude (HA). We tested the hypothesis that this phenotype is associated with impaired gas exchange and oxidative stress in the lungs. We used rats and mice (3 months old) living at HA (La Paz) and SL (Quebec City, Canada) to measure arterial oxygen saturation under graded levels of hypoxia (by pulse oximetry), the alveolar surface area in lung slices and the activity of pro- (NADPH and xanthine oxidases-NOX and XO) and anti- (superoxide dismutase, and glutathione peroxidase-SOD and GPx) oxidant enzymes in cytosolic and mitochondrial lung protein extracts...

There is little research to date on the academic implications of teaching twins in the same or different classroom. Consequently, it is not clear whether twin classroom separation is associated with positive or negative educational outcomes. As a result, parents and teachers have insufficient evidence to make a well-informed decision when twins start school. This study addresses two research questions: Are there average positive or negative effects of classroom separation? Are twins taught in different classes more different from each other than twins taught in the same class? Twin pairs from two large representative samples from Quebec (Canada) and the United Kingdom were evaluated across a large age range (7 to 16 years) on academic achievement, several cognitive abilities and motivational measures...

INTRODUCTION: Renal tumour biopsies (RTBs) can provide the histology of small renal masses (SRMs) prior to treatment decision making. However, many urologists are reluctant to use RTB as a standard of care. This study characterizes the current use of RTB in the management of SRMs and identifies barriers to a more widespread adoption. METHODS: A web-based survey was sent to members of the Canadian and Quebec Urological Associations who had registered email address (n=767) in June 2016...

Our objectives were to evaluate the prevalence of quarters with an observable internal teat sealant (ITS) plug at first milking following calving and investigate persistency of ITS residues in milk after calving. An observational cohort study was carried out on 557 quarters of 156 cows treated with ITS in 6 farms in Quebec, Canada. The presence of an ITS plug at first milking and ITS residues in milk at each milking were observed by producers. The effects of various factors on the odds of observing an ITS plug and persistency of ITS residues in milk were studied using generalized logistic mixed and generalized negative binomial mixed models, respectively...

Background -The possibility that congenital heart defects signal a familial predisposition to cardiovascular disease has not been investigated. We aimed to determine whether the risk of cardiovascular disorders later in life was higher for women who have had newborns with congenital heart defects. Methods -We studied a cohort of 1 084 251 women who had delivered infants between 1989 and 2013 in Quebec, Canada. We identified women whose infants had critical, noncritical, or no heart defects, and tracked the women over time for future hospitalizations for cardiovascular disease, with follow-up extending up to 25 years past pregnancy...

Instantaneous mitochondrial introgression events allow the disentangling of the effects of hybridization from those of allospecific mtDNA. Such process frequently occurred in the fish Chrosomus eos , resulting in cybrid individuals composed of a C. eos nuclear genome but with a C. neogaeus mtDNA. This provides a valuable model to address the fundamental question: How well do introgressed individuals perform in their native environment? We infer where de novo production of cybrids occurred to discriminate native environments from those colonized by cybrids in 25 sites from two regions (West-Qc and East-Qc) in Quebec (Canada)...

OBJECTIVES: This study sought to describe the recruitment of women living with HIV (WLWH) into the community-based Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS), because women are under-represented in HIV research. METHODS: There were 1,424 WLWH were enrolled from British Columbia, Ontario, and Québec, who completed detailed questionnaires administered by peer research associates (PRAs; WLWH with research training). During screening, participants were asked: "How did you hear about the study?" We describe recruitment strategies by subpopulation and offer reflections on challenges and successes...

ABSTRACTAlthough interest on older homelessness is gaining momentum, little research has considered the experiences of first-time homelessness from the perspective of older adults themselves. This constructivist grounded-theory study addresses this gap by exploring how societal perceptions of homelessness and aging shape access to housing, services, and perceptions of self for 15 older adults residing in emergency homeless shelters in Montreal, (Quebec, Canada). Findings revealed that homelessness evoked a grief response characterized by shock, despair, anger, and in some cases, relief...

INTRODUCTION: The challenges of global ageing and the growing burden of chronic diseases require innovative interventions acting on health determinants like social participation. Many older adults do not have equitable opportunities to achieve full social participation, and interventions might underempower their personal and environmental resources and only reach a minority. To optimise current practices, the Accompagnement-citoyen Personnalisé d'Intégration Communautaire (APIC), an intervention demonstrated as being feasible and having positive impacts, needs further evaluation...

BACKGROUND: The aim of this study to study the effect of visceral and subcutaneous fat tissue mass on short- and long-term prognosis of patients with acute calculus cholecystitis (ACC). METHODS: Retrospective analysis of medical records. Included were all patients admitted because of ACC. Computed tomography images at the level of L3 were analyzed for body composition using designated software (Slice-O-matic; TomoVision, Montreal, Quebec, Canada). General linear model was used to analyze the effect of body composition on length of hospital stay, and Cox regression analysis was used to ascertain the effect of the different parameters on 1-y survival...
