Psychiatr Q

December 2019

School of Social Work, Addiction Rehabilitation Center, National Capital University Integrated Health and Social Services Center, Laval University, Quebec City, Quebec, Canada.

Disproportionate use of emergency departments (EDs) by patients with mental disorders suggests the need to evaluate factors associated with ED use. Based on the Andersen Behavioral model, this mixed-method study identified the contributions of predisposing, enabling and needs factors in ED use among 328 patients with mental disorders. We hypothesised that ED use for mental health (MH) reasons would be most strongly associated with need factors.

August 2019

Schizophrenia and Neurodevelopmental Disorders Research Program, Douglas Mental Health University Institute, Verdun, QC, Canada; Department of Psychiatry, McGill University, Montreal, QC, Canada. Electronic address:

Background: It is well recognized that childhood sleep, attention and mood problems increase risk for multiple adverse outcomes across the life-span; therefore, understanding factors, such as prenatal maternal stress, that underlie these types of childhood problems is critical for developing interventions that may optimize longer-term functioning. Our goal was to determine the association between disaster-related stress in pregnancy and young children's sleep, attention, and anxious/depressed symptoms.

Methods: Soon after a major flood in Australia in 2011, we assessed various aspects of disaster-related prenatal maternal stress (PNMS) in women who had been pregnant at the time.

Multi-behavioral obesogenic phenotypes among school-aged boys and girls along the birth weight continuum.

PLoS One

November 2019

Desautels Faculty of Management, McGill Center for the Convergence of Health and Economics, McGill University, Montreal, QC, Canada.

Evidence shows that extremes of birth weight (BW) carry a common increased risk for the development of adiposity and related cardiovascular diseases, but little is known about the role of obesogenic behaviors in this process. Moreover, no one has empirically examined whether the relationship between BW, obesogenic behaviors and BMI along the full low-to-high birthweight continuum reflects the U-shape pattern expected from common risk at both BW extremes. Our objective was to characterize physical activity, screen time, and eating behavior and their relationship to BMI as a function of BW among school-aged boys and girls.

Department of Psychology, University of Konstanz, Konstanz, Germany; Prevention and Early Intervention Program for Psychosis, Douglas Mental Health University Institute, McGill University, Department of Psychiatry, Montreal, Quebec, Canada. Electronic address:

Psychosis has been associated with abnormalities in hypothalamic-pituitary-adrenal axis functioning, which may emerge through heightened stress sensitivity following early life adversity - ultimately resulting in illness onset and progression. The present study assessed cortisol levels during an established psychosocial stress task and their association with current stress perception, putative protective factors and adverse childhood experiences in patients with a first episode of psychosis (FEP). A total of 100 volunteers participated in the study, 57 of whom were patients with a FEP (mean age 23.

Analysis of "" data is often a long and segmented process, encompassing multiple stages from initial data collection to processing, quality control and visualization. The cross-modal nature of recent genomic analyses renders this process challenging to both automate and standardize; consequently, users often resort to manual interventions that compromise data reliability and reproducibility. This in turn can produce multiple versions of datasets across storage systems.

Neuropeptides are auxiliary messenger molecules that always co-exist in nerve cells with one or more small molecule (classic) neurotransmitters. Neuropeptides act both as transmitters and trophic factors, and play a role particularly when the nervous system is challenged, as by injury, pain or stress. Here neuropeptides and coexistence in mammals are reviewed, but with special focus on the 29/30 amino acid galanin and its three receptors GalR1, -R2 and -R3.

Electronic address:

Astrocytic contributions to Alzheimer's disease (AD) progression were, until recently, largely overlooked. Astrocytes are integral to normal brain function and astrocyte reactivity is an early feature of AD, potentially providing a promising target for preclinical diagnosis and treatment. Several in vivo AD biomarkers already exist, but presently there is a paucity of specific and sensitive in vivo astrocyte biomarkers that can accurately measure preclinical AD.

The aim of this study was to investigate whether maternal cafeteria ingestion interferes with long-term memory-related behaviors and hippocampal brain-derived neurotrophic factor (BDNF) signaling in the offspring, and if there is a cumulative effect with the exposure to cafeteria diet during the life-course of the pups. Female rats were fed a control (CON, n = 20) or cafeteria diet (CAF, n = 24) from their weaning to weaning of their offspring. After that, their male offspring were divided into 4 groups (CON-CON, n = 36; CON-CAF, n = 38, CAF-CON, n = 46 and CAF-CAF, n = 39) so that all litters ingested CON or CAF, irrespective of maternal diet.
