Prognostic models for depression and post-traumatic stress disorder symptoms following traumatic brain injury: a CENTER-TBI study.

Background: Traumatic brain injury (TBI) is associated with an increased risk of major depressive disorder (MDD) and post-traumatic stress disorder (PTSD). We aimed to identify predictors and develop models for the prediction of depression and PTSD symptoms at 6 months post-TBI.

Methods: We analysed data from the Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury study.

Revered and Reviled: The Plight of the Vanishing Sea Cucumbers.

Sea cucumbers paradoxically suffer from being both highly prized and commonly disregarded. As an Asian medicine and delicacy, they command fabulous prices and are thus overfished, poached, and trafficked. As noncharismatic animals, many are understudied and inadequately protected.

Antipsychotic Drug Prescribing in Children Previously Treated With Stimulants for ADHD: A Population-Based Longitudinal Study: La prescription d'antipsychotiques chez les enfants précédemment traités avec des stimulants pour le TDAH : une étude longitudinale basée sur la population.

Objective: Stimulant drug treatment in preschool-age children for attention-deficit hyperactivity disorder (ADHD) as well as the concomitant use of antipsychotic drugs is largely unstudied in terms of longitudinal outcomes. We characterized longitudinal patterns of stimulant drug use in children diagnosed for ADHD and analyzed the mental health disorders leading to add-on therapy with antipsychotics.

Method: The study population comprised of children and adolescents (age: 0-19 years) in the province of British Columbia (BC), Canada, with at least one dispensing for any psychotropic drug between 1997 and 2017 ( = 144,825).

Acute selective serotonin-reuptake inhibition elevates basal ventilation, attenuates the rebreathing ventilatory response, independent of cerebral perfusion.

Serotonin (5-HT) is integral to signalling in areas of the brainstem controlling ventilation and is involved in central chemoreception. Selective serotonin reuptake inhibitors (SSRIs), used to effectively increase 5-HT concentrations, are commonly prescribed for depression. The effects of SSRIs on the control of breathing and the potential influence of cerebral blood flow (CBF) have not been directly assessed.

Ketone monoester ingestion improves cardiac function in adults with type 2 diabetes: a double-blind, placebo controlled, randomised, crossover trial.

Type 2 diabetes (T2D) is a metabolic disease associated with cardiovascular dysfunction. The myocardium preferentially uses ketones over free fatty acids as a more energy efficient substrate. The primary aim was to assess the effects of ketone monoester (K) ingestion on cardiac output index ().

Ambient Temperature Isolation of a Monatomic Boron(0) Complex.

The first bottleable example of a neutral Group 13 atom bound only by neutral donor ligands (L) has been fully characterized by spectroscopic methods and its structure determined by a single-crystal X-ray diffraction study. A two-coordinate paramagnetic LB complex can readily be accessed through a facile reduction reaction and is stabilized by π-accepting cyclic (alkyl)(amino)carbene (CAAC) ligands. Further reduction of (CAAC)B leads to the isolation of a stable diamagnetic boride anion.

Science tells us that portable air filters reduce infection risk. It's time for public health authorities to make this clear.

Throughout the COVID-19 pandemic, Canadian public health advisors and politicians have shared mixed messages about the utility of portable air filters (PAFs) for mitigating the transmission of airborne infectious diseases. Some public health advisors and decision-makers have also suggested that PAFs are cumbersome or require expert advice. We take this opportunity to review evidence and address myths about PAFs.

Accounting for the role of the gastro-intestinal tract in the ammonia and urea-N dynamics of freshwater rainbow trout on long-term satiation feeding.

The contribution of the gut to the ingestion, production, absorption, and excretion of the extra ammonia and urea-N associated with feeding ("exogenous" fraction) has received limited prior attention. Analysis of commercial pellet food revealed appreciable concentrations of ammonia and urea-N. Long term satiation-feeding increased whole trout ammonia and urea-N excretion rates by 2.

Metal Mobilization from Thawing Permafrost Is an Emergent Risk to Water Resources.

Metals are ubiquitous in Earth's Critical Zone and play key roles in ecosystem function, human health, and water security. They are essential nutrients at low concentrations, yet some metals are toxic at a high dose. Permafrost thaw substantially alters all the physical and chemical processes governing metal mobility, including water movement and solute transport and (bio)geochemical interactions involving water, organic matter, minerals, and microbes.

Considering veno-venous extracorporeal membrane oxygenation as a first-line strategy for rewarming in accidental hypothermia complicated by cardiac arrest - a case series.

Severe accidental hypothermia can lead to cardiac arrest. The most efficient method of resuscitating and warming is by ECMO (Extracorporeal Membrane Oxygenation). While the convention is to use VA ECMO (Veno Arterial ECMO), using VV ECMO (Veno Venous ECMO) in which the blood is returned directly into the right ventricle could be an alternative and lead to conversion to life sustaining cardiac rhythm.

An ML-Enhanced Laser-Based Methane Slip Sensor Using Wavelength Modulation Spectroscopy.

Natural gas (NG) is a promising alternative to diesel for sustainable transport, potentially reducing GHG and air quality emissions significantly. However, the GHG benefits hinge on managing methane slip, the unburned methane in the exhaust of NG engines, which carries a significant global warming potential. The CH slip from NG engines is highly dependent on engine type and operation, and effective greenhouse gas emission mitigation requires that the actual operation of real-world engines is monitored.
