Background: Postpartum post-traumatic stress disorder (PTSD) is a debilitating condition that can arise following childbirth. Despite a growing body of research on postpartum mental health, the relationship between social support and postpartum PTSD remains unclear. This study aimed to assess the association between social support and postpartum PTSD.

Objective: There is no clear evidence on the risk of gestational weight loss (GWL) for individuals with obesity. Our study aimed to assess the association between GWL and adverse perinatal outcomes among individuals with obesity.
Methods: This population-based retrospective cohort study examined individuals with prepregnancy BMI ≥ 30 kg/m who had a singleton pregnancy, using Ontario, Canada, birth registry data from 2012 to 2020.
Background: Adverse childhood experiences (ACEs) are known contributors to lifelong mental health challenges. Despite studies linking ACEs to increased risk of adverse postpartum mental health outcomes, a systematic review on the occurrence of postpartum post-traumatic stress disorder (PTSD) in women with ACEs is lacking.
Methods: A systematic search was conducted in seven databases to retrieve studies from inception to January 31, 2024.
Introduction: Although the benefits of doula care during childbirth are well-known, its impact on childbirth-related post-traumatic stress disorder (CB-PTSD) symptoms are less thoroughly characterized. This study aimed to explore the association between doula care and CB-PTSD symptoms and the potential mediating role of childbirth experience on this association.
Methods: A prospective cohort study was conducted in a hospital in China, enrolling women with singleton live vaginal births.
The direction and magnitude of association between maternal exposure to ambient air pollutants across gestational windows and offspring risk of autism spectrum disorders (ASD) remains unclear. We sought to evaluate the time-varying effects of prenatal air pollutant exposure on ASD. We conducted a matched case-control study of singleton term children born in Ontario, Canada from 1-Apr-2012 to 31-Dec-2016.

We analyzed trends in GDM rates and evaluated risk factors associated with the observed trends in Ontario, Canada.
Methods: We conducted a retrospective population-based cohort study using the Better Outcomes Registry and Network Ontario, linked with the Canadian Institute for Health Information Discharge Abstract Database.
Introduction: Understanding the mechanisms underlying maternal postpartum depression (PPD) and its effects on offspring development is crucial. However, research on the association between maternal PPD, gut microbiota, and offspring neurodevelopment remains limited. This study aimed to examine the association of maternal PPD symptoms with early gut microbiome, gut metabolome, and neurodevelopment in infants at 6 months.

We sought to determine the association between CDMR and infant infection using an intent-to-treat approach.
Methods: This was a population-based cohort study of low-risk singleton pregnancies with a term live birth in Ontario, Canada between April 2012 and March 2018.
Background: Increasing evidence links early life residential exposure to natural urban environmental attributes and positive health outcomes in children. However, few studies have focused on their protective effects on the risk of autism spectrum disorder (ASD). The aim of this study was to investigate the associations of neighborhood greenspace, and active living environments during pregnancy with ASD in young children (≤6 years).

The objectives of this study were to thoroughly reviewed and analyzed relevant literature and to propose a hypothesis that may explain this paradox phenomenon. We conducted a search of literature from three English databases (EMBASE, MEDLINE, and Google Scholar) from inception to 13 November 2023.

We sought to compare the risk of stillbirth associated with maternal obesity alone versus maternal obesity and additional or undiagnosed factors contributing to high-risk pregnancy.
Methods: We conducted a retrospective cohort study using the Better Outcomes Registry and Network (BORN) for singleton hospital births in Ontario between 2012 and 2018.
Aim: To assess the thyroid allostasis in drug-free patients with affective disorder.
Methods: Patients with major depressive disorder or bipolar disorder as drug-free, defined as those without psychiatric drugs exposure for at least 4 months before admission, from a tertiary hospital were recruited in this cross-sectional study. The primary outcomes were "structure parameters of thyroid homeostasis", which include "thyroid's secretory capacity" (SPINA-GT), "sum step-up activity of deiodinases" (SPINA-GD), the ratio of total to free thyroxine and "thyroid homeostasis central set point" (TSH index and "thyroid feedback quantile-based index" [TFQI]), calculated by TSH and thyroid hormones measured at admission.
Introduction: Interpregnancy weight change may impact two important adverse perinatal outcomes: stillbirth and infant mortality. This systematic review aims to synthesise the existing evidence on the association between interpregnancy weight change and stillbirth and infant mortality.
Methods And Analysis: This systematic review and meta-analysis will be conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses Protocols guidelines and has been registered in the International Prospective Register of Systematic Reviews (PROSPERO).
Objective: Gestational weight gain (GWG) outside recommended ranges can negatively impact both the woman and child. The long-term effects of below-recommended or above-recommended GWG on the child are unclear.
Methods: This retrospective cohort study used a population-based birth registry of 258,005 live births to evaluate the relationship between maternal GWG and paediatric health service use.
Background: Maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) above or below recommendations have been associated with increased paediatric health service utilization as well as increased risk of adverse birth outcomes, including small for gestational age (SGA) and preterm birth (PTB). SGA and PTB are associated with numerous adverse health outcomes in the child, including delayed growth, motor and cognitive impairment. Previous research has identified birth weight and gestational age on the causal pathway in the association between maternal pre-pregnancy BMI and child hospital admissions, there are no studies to date to quantify this relationship across other areas of health service utilization, nor the impact of gestational weight gain.

This scoping review is designed to broadly capture all potential interventions for the secondary prevention of IPV, review them in detail, and assess what can reduce revictimisation and foster improvements in both maternal and neonatal outcomes.
Methods And Analysis: With the structure of the Joanna Briggs Institute and Arksey and O'Malley methodology for scoping reviews, the search will be conducted in: MEDLINE(R) ALL (OvidSP), Embase (OvidSP), CINAHL (EBSCOHost), APA PsycInfo (OvidSP), Cochrane Central Register of Controlled Trials (OvidSP), Web of Science, and Applied Social Sciences Index & Abstracts (ProQuest).
Background: The 2019 novel coronavirus (COVID-19) pandemic remains rampant in many countries/regions. Improving the positive detection rate of COVID-19 infection is an important measure for the control and prevention of this pandemic. This meta-analysis aims to systematically summarize the current characteristics of the computed tomography (CT) auxiliary screening methods for COVID-19 infection in the real world.

Vaginal microbiota transfer (VMT) to newborns may reverse C-section-related microbiome disturbances. Here, we evaluated the effect of VMT by exposing newborns to maternal vaginal fluids and assessing neurodevelopment, as well as the fecal microbiota and metabolome.

Although the evidence regarding the association between gestational diabetes mellitus (GDM) and subsequent CVD has been synthesised, there are no systematic reviews covering the evidence of the association among the non-GDM population. This systematic review and meta-analysis, therefore, aim to fill the gap by summarising existing evidence on the association between maternal glucose levels and the risk of future CVD in pregnant women with or without a diagnosis of GDM.
