Article Synopsis
  • Penicillin allergies often lead to unnecessary treatment delays, as many reported allergies are not true allergies; efficient tools are needed to identify low-risk patients for safe de-labeling.
  • The FIRSTLINE electronic decision support tool was implemented to help clinicians assess and stratify penicillin allergy risk among pregnant women in Vancouver, with a focus on its reliability compared to allergist evaluations and other tools like JAMA and PENFAST.
  • Results showed that 97.2% of 181 patients were not allergic, and FIRSTLINE effectively identified a high percentage of low-risk patients, emphasizing the value of clinical algorithms in improving patient care.

Background: For pregnant women living with HIV (WLWH), engagement in care is crucial to maternal health and reducing the risk of perinatal transmission. To date, there have been no studies in Canada examining the impact of the COVID-19 pandemic on pregnant WLWH.

Methods: This was a retrospective cohort study assessing the impact of the pandemic on perinatal outcomes for pregnant WLWH using data from the Perinatal HIV Surveillance Program in British Columbia, Canada.

Background: Inaccurate penicillin allergy labels lead to inappropriate antibiotic prescriptions and harmful patient consequences. System-wide efforts are needed to remove incorrect penicillin allergy labels, but more health services research is required on how to best deliver these services.

Methods: Data was extracted from five hospitals in Vancouver, British Columbia, Canada from October 2018-May 2022.

Birth mode has been implicated as a major factor influencing neonatal gut microbiome development, and it has been assumed that lack of exposure to the maternal vaginal microbiome is responsible for gut dysbiosis among caesarean-delivered infants. Consequently, practices to correct dysbiotic gut microbiomes, such as vaginal seeding, have arisen while the effect of the maternal vaginal microbiome on that of the infant gut remains unknown. We conducted a longitudinal, prospective cohort study of 621 Canadian pregnant women and their newborn infants and collected pre-delivery maternal vaginal swabs and infant stool samples at 10-days and 3-months of life.

Background: Women represent one quarter of the population living with HIV in Canada and are an increasingly important sector of the HIV community. While some women's health issues such as cervical cancer screening and management are well addressed in HIV management guidelines, others are not. These include sexual and reproductive health factors such as contraception, pre-conception planning, and menopause.

Importance: There are limited high-quality, population-level data about the effect of SARS-CoV-2 infection on pregnancy using contemporaneous comparator cohorts.

Objectives: To describe maternal and perinatal outcomes associated with SARS-CoV-2 infection in pregnancy and to assess variables associated with severe disease in the pregnant population.

Design, Setting, And Participants: CANCOVID-Preg is an observational surveillance program for SARS-CoV-2-affected pregnancies in Canada.

People living with HIV are ageing, and a growing number of women living with HIV are entering menopause. Women living with HIV commonly have bothersome vasomotor symptoms and onset of menopause at earlier ages; both factors go on to affect quality of life and systemic health. Vasomotor symptoms and early menopause are both indications for menopausal hormone therapy; however, current evidence suggests that this therapy is seldom offered to women living with HIV.

Sepsis is one of the leading causes of maternal morbidity and mortality. Analyses have determined that delays in early recognition and prompt initiation of appropriate management are key contributing factors in maternal sepsis deaths. Recent cases of sepsis-related maternal morbidity and mortality across Canada have highlighted the urgent need for a national standardized approach to the detection and treatment of maternal sepsis.

Article Synopsis
  • The study focused on understanding the factors that contribute to preterm birth (PTB) in women living with HIV in British Columbia, Canada, while examining the effects of combined antiretroviral therapy (cART) and other health determinants.
  • It analyzed data from 631 singleton pregnancies and found that the overall spontaneous preterm birth (sPTB) rate was 16%, with cumulative cART use linked to a reduced risk of sPTB.
  • The findings concluded that while sPTB rates among pregnant women with HIV were significantly higher than the general population, cART use did not increase the risk; instead, issues like uncontrolled viral load and substance use were more strongly associated with higher sPTB

To evaluate the association of antiretroviral therapy (ART) type and duration of exposure with early placental function using biomarkers of aneuploidy screening. Three hundred thirty-eight pregnant women living with HIV were enrolled in two Canadian centers. Multiple linear regressions were performed adjusting for confounding factors (race, age, gestational age, body mass index, parity, smoking, and fetal sex).

La consommation du placenta humain a récemment été mise en évidence. Toutefois, aucune donnée probante ne fait état des bienfaits qui seraient liés à cette pratique. De plus, elle peut nuire à la santé.

Consumption of human placenta has recently been highlighted; however, there is no evidence of benefit from its consumption. In addition, there is potential for harm. Therefore the SOGC does not recommend the practice of placentophagy.
