Many chemicals associated with unconventional oil and natural gas (UOG) are known toxicants, leading to health concerns about the effects of UOG. Our objective was to conduct a scoping review of the toxicological literature to assess the effects of UOG chemical exposures in models relevant to human health. We searched databases for primary research studies published in English or French between January 2000 and June 2023 on UOG-related toxicology studies.

Pharmacogenomic (PGx) testing may increase the probability of remission and response in patients with major depressive disorder (MDD) undergoing pharmacotherapy. Given the potential implications of these outcomes and recent proliferation of PGx studies, we conducted a systematic review to evaluate the effectiveness of PGx testing on clinical outcomes in patients with MDD as compared to treatment as usual (TAU). MEDLINE, Embase, PsycInfo, and CENTRAL were searched for English-language articles from 2000 to 2021 for randomized controlled trials (RCTs) comparing PGx-guided treatment vs.

Background: Genome-based precision medicine strategies promise to minimize premature graft loss after renal transplantation, through precision approaches to immune compatibility matching between kidney donors and recipients. The potential adoption of this technology calls for important changes to clinical management processes and allocation policy. Such potential policy change decisions may be supported by decision models from health economics, comparative effectiveness research and operations management.

Background: Patients who experience harms from alcohol and other substance use often seek care in the emergency department (ED). ED visits related to alcohol withdrawal have increased across the world during the COVID-19 pandemic. ED clinicians are responsible for risk-stratifying patients under time and resource constraints and must reliably identify those who are safe for outpatient management versus those who require more intensive levels of care.

Plain English Summary: The Canadian Institutes of Health Research funded a program, "patient-oriented research" (POR), to change the way health research is done. POR involves patients and their families/caregivers as equal partners on research teams with researchers, healthcare providers and decision-makers. The authors of this paper work through a unit in British Columbia, Canada that functions to help research teams learn how to do patient-oriented research.

Background: North America is in the midst of an unabated opioid overdose epidemic due to the increasing non-medical use of fentanyl and ultra-potent opioids. Naloxone is an effective antidote to opioid toxicity, yet its optimal dosing in the context of fentanyl and ultra-potent opioid overdoses remains unknown. This review aims to determine the relationship between the first empiric dose of naloxone and reversal of toxicity, adverse events, and the total cumulative dose required among patients with undifferentiated opioid overdoses and those with suspected toxicity from ultra-potent opioids.

Background: Patient-Oriented Research (POR) is a Canadian initiative for health research that refers to research processes informed by full and active patient involvement in all aspects of the research. Ideally, POR results in a wide dissemination of the research findings and the uptake of such findings in both clinical practice and health policy. The Canadian Institute for Health Research (CIHR) identifies four stakeholder groups that are involved in POR who are envisioned to take on a collaborative role in enacting this approach to research.

Background: Opioid addiction prevention has become an urgent public health priority, with several countries declaring a state of emergency due to rising death tolls from opioid abuse. Reducing the risk of developing addiction among opioid-naïve patients exposed to prescribed opioids during the process of medical care may be an important primary prevention strategy. Our objective is to synthesize the available evidence about factors associated with the development of addiction among patients first exposed to prescribed opioids, with a focus on opioid-naïve patients.

Background: The term "health literacy" (HL) was first coined in 1974, and its most common definition is currently defined as a person's ability to access, understand, evaluate, communicate, and use health information to make decisions for one's health. The previous systematic reviews assessing the effect of existing HL measurement tools on health outcomes have simply searched for the term "health literacy" only to identify measures instead of incorporating either one or more of the five domains in their search. Furthermore, as the domain "use" is fairly new, few studies have actually assessed this domain.
