Our study investigated the age-adjusted incidence rates of non-fatal overdoses by HIV status and sex, and examined trends over time.
We used data from the Comparative Outcomes and Service Utilization Trends study, a population-based cohort study that includes clinical and administrative health data on virtually all people with HIV (PWH) and a 10% random sample of people without HIV in the province.
British Columbia, Canada.
Between April 2012 and March 2020, 11 050 PWH (81.8% male) and 473 952 people without HIV (50.3% male) who were 19 years and older contributed 68 035 and 3 285 824 person years (PY) of follow-up, respectively.
The primary outcome was age-adjusted incidence rates of non-fatal overdose events stratified by sex and HIV status. Trends over time were also assessed.
Age-adjusted non-fatal overdose incidence rates among males with and without HIV were 36.4 and 3.12 per 1000 PY, respectively (incidence rate ratio (IRR) = 11.7, 95% CI 10.9 to 12.5). For females with and without HIV, the age-adjusted incidence rates were 61.4 and 2.33 per 1000 PY, respectively (IRR=26.3, 95% CI 24.0 to 28.7). Between 2013 and 2019 (calendar years with full-year data), the age-adjusted non-fatal overdose rate increased significantly among males and females without HIV but not among PWH.
We observed a significantly higher non-fatal overdose rate among PWH compared to people without HIV. The rate was highest among females with HIV. These findings underline the need for policies and programmes oriented towards PWH to mitigate overdoses, especially for females.
In the last 60 years, newborn bloodspot screening (NBS) has expanded as a public health intervention from a single severe childhood genetic disease (SCGD) to up to as many as 80 SCGD and testing of ~40 million newborns/year worldwide. However, the gap between current NBS and its potential to increase the efficiency, effectiveness and global equity of healthcare delivery for SCGD is large and rapidly growing. There are now effective therapeutic interventions—drugs, diets, devices and surgeries—for up to 2000 SCGD. Since almost all SCGD can be identified by bloodspot genome sequencing, it has been a longstanding goal to supplement current NBS with genome sequencing-based NBS (gNBS) for all eligible SCGD. We recently described a novel gNBS platform (named Begin Newborn Genome Sequencing (BeginNGS)) with the potential to overcome several major challenges to gNBS (cost, scalability, false positives and an unprepared healthcare workforce). A pilot clinical trial of BeginNGS for 412 SCGD in a level IV neonatal intensive care unit (NICU) had a true positive rate of 4.2%, sensitivity of 83%, positive predictive value of 100% and clinical utility rate of 4.2%, indicating readiness of the platform for use in a powered, multicentre study.
The BeginNGS study is a single group, international, multicentre, adaptive clinical trial to compare utility, acceptability, feasibility and cost-effectiveness of BeginNGS gNBS (experimental intervention) with standard NBS (control). A minimum of 10 000 neonates (aged 50 000 US children per year.
This study was approved by the WCG Clinical institutional review board on 14 February 2024, and the most recent amendment approved on 7 October 2025 (approval number 20235517). Study findings will be shared through research consortium workshops, national and international conferences, community presentations and peer-reviewed journals.
Within the Canadian context, we sought to examine the relationship between households with autistic children/youths and household income.
We used data from the 2019 Canadian Health Survey on Children and Youth (CHSCY) to analyse households with a child/youth aged 1–17. Propensity-score matching was used to pair records for children/youths with a reported autism diagnosis to those without. We used linear regression for continuous outcomes (eg, total household income) and Poisson regression for binary outcomes (eg, low household income). All analyses were adjusted for the correlation between matched pairs.
Total annual income of all household members.
Low household income; single-parent or single-income status; and whether at least one parent was not working or absent from work during the past week.
Among a total of 39 951 CHSCY records, we identified a cohort of 815 autistic children/youths. The characteristics of the matched cohort were well-balanced. Households with an autistic child/youth had a mean annual household income that was lower (mean difference: $C16 489; 95% CI $C6384 to $C27 149) compared with matched households without an autistic child/youth. Households with an autistic child/youth were also 26% more likely to be classified as having a low household income (Relative risk (RR)1.26; 95% CI1.17 to 1.35) and 20% more likely to rely on a single income (RR1.20; 95% CI 1.10 to 1.33) compared with households without an autistic child/youth.
Compared with households without an autistic child/youth, those with an autistic child/youth often face more economic challenges, including lower household income and greater risk of food insecurity. Households with an autistic child/youth are more likely to rely on a single income.
Drug and vaccine safety information relevant to pregnant individuals is typically insufficient, especially so for persons living in low- and middle-income countries (LMICs). Pregnancy exposure registries (PERs) and similar systems are used to monitor medical products safety. A better understanding of the landscape of PERs in LMICs can support medicines regulatory system strengthening and preparation for new vaccine and drug introductions.
To identify PERs and related health data collection platforms in LMICs that systematically record pregnancy exposures to medical products and pregnancy outcomes to inform how future efforts, such as new vaccine introductions and treatment programmes, can better support maternal populations in these countries.
Scoping review based on methodology outlined in the Joanna Briggs Institute manual for scoping reviews.
Electronic search of Medline/PubMed, Embase, CINAHL and Global Index Medicus in June 2022, and key informants via online survey in July 2022 and interviews.
Eligible resources included registries, surveillance systems and databases that collect information on exposures to medical products during pregnancy and on subsequent maternal, perinatal and neonatal outcomes in populations located entirely or partially in LMICs. Eligible records were published from January 2000 through June 2022.
Search results were screened and data extracted using a standardised form by two independent reviewers. Instances of discordance were resolved by a third reviewer. Identified systems were categorised by resource type.
A total of 7515 records from electronic searches were screened, with 396 selected for full-text review and 47 additional records obtained from other sources. From these, 45 data collection systems located in African, Asian and Latin American LMICs were identified, with 36 currently in operation. These resources were grouped into six categories based on structure and approach and summarised according to key features, strengths and weaknesses.
This scoping review identified several resources in LMICs dedicated to drug and vaccine safety in pregnancy, but findings indicate that more investment will be needed to ensure such efforts are widespread and sustainable. Understanding the current landscape of such resources in these settings is an important step towards improving safe, world-wide access to life-saving interventions for pregnant populations.
