A tiered assessment of human health risks associated with exposure to persistent, mobile and toxic chemicals via drinking water.

There is increasing interest in chemicals which are persistent, mobile and toxic (PMT), primarily to protect drinking water. We present a tiered assessment of drinking water exposure and associated human health risks for 22 PMT substances. Worst-case exposure via drinking water is assumed to occur when wastewater is discharged to rivers which are then abstracted for water supply.

A Systematic Review of Social Support Instruments for Measurement-Based Care in Posttraumatic Stress Disorder.

Purpose: Social support is a treatment target for individuals with post-traumatic stress disorder (PTSD) but is not systematically assessed in clinical care. This review evaluated the quality of patient-reported social support instruments used in PTSD research to identify candidates for measurement-based care (MBC) with this population.

Method: A systematic review identified all validated measures of social support used in research with traumatized populations after 1990.

Stop the Bleed-Wait for the Ambulance or Get in the Car and Drive? A Post Hoc Analysis of an EAST Multicenter Trial.

The Stop the Bleed campaign gives bystanders an active role in prehospital hemorrhage control. Whether extending bystanders' role to private vehicle transport (PVT) for urban penetrating trauma improves survival is unknown, but past research has found benefit to police and PVT. We hypothesized that for penetrating trauma in an urban environment, where prehospital procedures have been proven harmful, PVT improves outcomes compared to any EMS or advanced life support (ALS) transport.

Local Dynamics of Intersectional Stigma for Black LGBTQ People in Montreal, Quebec.

Much academic literature on intersectional stigma is limited by a focus on relatively static and "universal" identity traits, such as ethnicity, gender, and sexuality. This paper addresses local dynamics of intersectional stigma for Black LGBTQ people in Montreal, QC, Canada. Findings draw from fourteen semi-structured, virtual interviews with key informants providing critical services to Black LGBTQ people living in Montreal.

Tranexamic Acid and Pulmonary Complications: A Secondary Analysis of an EAST Multicenter Trial.

Background: Anti-inflammatory effects of tranexamic acid (TXA) in reducing trauma endotheliopathy may protect from acute lung injury. Clinical data showing this benefit in trauma patients is lacking. We hypothesized that TXA administration mitigates pulmonary complications in penetrating trauma patients.
