Enhancing surface drainage mapping in eastern Canada with deep learning applied to LiDAR-derived elevation data.

Agricultural dykelands in Nova Scotia rely heavily on a surface drainage technique called land forming, which is used to alter the topography of fields to improve drainage. The presence of land-formed fields provides useful information to better understand land utilization on these lands vulnerable to rising sea levels. Current field boundaries delineation and classification methods, such as manual digitalization and traditional segmentation techniques, are labour-intensive and often require manual and time-consuming parameter selection.

Whole-brain morphometry in Canadian soldiers with posttraumatic stress disorder.

Patients with posttraumatic stress disorder (PTSD) display several structural brain differences when compared with healthy individuals. However, findings are particularly inconsistent for soldiers with PTSD. Here, we characterized the brain morphometry of 37 soldiers from the Canadian Armed Forces with adulthood war-related PTSD using structural magnetic resonance imaging.

Four Decades of Military Posttraumatic Stress: Protocol for a Meta-analysis and Systematic Review of Treatment Approaches and Efficacy.

Background: Over 85% of active members of the Canadian Armed Forces have been exposed to potentially traumatic events linked to the development of posttraumatic stress disorder (PTSD). At the time of transition to civilian life, as high as 1 in 8 veterans may be diagnosed with PTSD. Given the high prevalence of PTSD in military and veteran populations, the provision of effective treatment considering their unique challenges and experiences is critical for mental health support and the well-being of these populations.

Duloxetine in adults with ADHD: a randomized, placebo-controlled pilot study.

Objective: To assess the effect of duloxetine on ADHD in adults.

Method: In a 6-week double-blind trial, 30 adults with ADHD received placebo or duloxetine 60 mg daily. The Conners' Adult ADHD Rating Scale (CAARS) and the Clinical Global Impression Scales (CGI) were used to assess symptom severity and clinical improvement.

Staff perceptions and organizational factors as predictors of seclusion and restraint on psychiatric wards.

Objective: Several factors have been shown to be involved in decisions to use seclusion and restraint in psychiatric inpatient settings. This study examined whether staff perceptions of factors related to the care team and violence on the ward predicted use of seclusion and restraint in psychiatric wards.

Methods: A total of 309 staff members (nurses, rehabilitation instructors, and nurse's aides) providing care to patients with serious mental disorders were recruited from eight university psychiatric hospitals and general-hospital psychiatric units in the province of Quebec.

Depolymerization of steam-treated lignin for the production of green chemicals.

In this short communication, lignin produced by steam processing of agricultural (hemp) and forestry (softwood) was depolymerised via a base catalysis to produce a combination of monomers, dimers, trimers and residual char. The lignin broth produced directly after the base-catalysed steam treatment was treated under pressure (from 1300 to 1900 psi) at temperatures varying from 300 to 330 °C in a custom-made batch reactor. The lignin concentration in the aqueous base solution was 10 wt% whilst the NaOH concentration was 5 wt%.

Improvement with duloxetine in an adult ADHD patient.

Introduction: Attention-deficit/hyperactivity disorder (ADHD) is a common and disabling disorder among adults and is treated with stimulant and non stimulant medication.

Objective: To report the case of a patient with ADHD showing good clinical response to duloxetine, a selective serotonin and norepinephrine reuptake inhibitor (SSNRI).

Case Presentation: A 53 year-old man with a recently diagnosed ADHD was successfully treated with duloxetine 60 mg and showed reduced scores on the Conners' Adult ADHD Rating Scales - Self-Report Scale: Short Version (CAARS-S:S).
