Anti-migraine medications safety during pregnancy in the US.

Background: Specific antimigraine medications (dihydroergotamine (DHE), triptans) have been associated with adverse pregnancy outcomes in individual studies but lack of consensus remains.

Objectives: Quantify the risk of prematurity, low birth weight (LBW), major congenital malformations (MCM), and spontaneous abortions (SA) associated with gestational use of DHE or triptans in a privately insured cohort of pregnant women in the US.

Methods: We conducted a cohort study within the US Merative MarketScan Research Database (2011-2021), composed of a nationally representative sample of patients with employer-provided health insurance.

Impact of Vanessa's Law on the Reporting of Serious Adverse Events: A Retrospective Study Among Antiplatelet Users in a Tertiary-Care Cardiology Centre.

Background: Antiplatelet drugs, such as clopidogrel, ticagrelor, prasugrel, and acetylsalicylic acid, may be associated with a risk of adverse events (AEs). Vanessa's Law was enacted to strengthen regulations to protect Canadians from drug-related side effects (with mandatory reporting of serious adverse events [SAEs]).

Objective: To determine whether Vanessa's Law has led to an increase in SAE reporting among antiplatelet users.

Etiological study of polyclonal hypergammaglobulinemia in a French cohort of hospitalized patients and proposal of a diagnostic aid algorithm : Short title: polyclonal hypergammaglobulinemia in a French cohort of hospitalized patients.

Serum protein electrophoresis can sometimes reveal polyclonal hypergammaglobulinemia. This electrophoretic abnormality can be caused by a variety of conditions and can be difficult to investigate. We sought to investigate screening practices in patients with hypergammaglobulinemia in order to establish diagnostic guidance strategies.

Association between maternal schizophrenia and risk of serious asthma exacerbations in childhood.

Background And Hypothesis: While maternal schizophrenia is linked to chronic childhood medical conditions, little is known about the risk of acute asthma exacerbations among children whose mothers have schizophrenia. This population-based study used health data for all of Ontario, Canada to evaluate whether having a mother with schizophrenia was associated with increased risk of asthma exacerbations.

Study Design: The study cohort included 385,989 children diagnosed with asthma from age 2 years onward, followed from the time of their asthma diagnosis up to a maximum of age 19 years.

Underreporting of adverse events to health authorities by healthcare professionals: a red flag-raising descriptive study.

Background: An adverse event (AE) is any undesirable medical manifestation in an individual who has received pharmacological treatment. To be considered serious (SAE), it needs to meet minimally one of the severity criteria by Health Canada. The most recent data (2006) suggested that AEs were underreported (<6%) to health authorities.

Computational Microbiome Pharmacology Analysis Elucidates the Anti-Cancer Potential of Vaginal Microbes and Metabolites.

The vaginal microbiome's role in risk, progression, and treatment of female cancers has been widely explored. Yet, there remains a need to develop methods to understand the interaction of microbiome factors with host cells and to characterize their potential therapeutic functions. To address this challenge, we developed a systems biology framework we term the Pharmacobiome for microbiome pharmacology analysis.

A Description of the THRIVE (The Study of Host-Bacterial Relationships and Immune Function in Different Vaginal Environments) Bacterial Vaginosis Observational Study.

Objectives: Bacterial vaginosis (BV) contributes to poor reproductive health and is characterized by a displacement of Lactobacillus in the vaginal microbiome. However, treatment for BV is limited to antibiotics and half of the women treated experience recurrence within a year. THRIVE (The Study of Host-Bacterial Relationships and Immune Function in Different Vaginal Environments) is a prospective study in Winnipeg, Manitoba, Canada, which is designed to capture the daily variation of the microbiome and host mucosal immunity during treatment.

Novel phages of unveil numerous potential auxiliary metabolic genes.

Relatively few phages that infect plant pathogens have been isolated and investigated. The species complex is present in various environments, including plants. It can cause major crop diseases, such as bacterial canker on apricot trees.

Associations between Prepartum and Postpartum Maternal Symptoms of Depression, Anxiety and Stress Related to COVID-19 Pandemic and Childhood Sensory Avoidance: Results from Conception Study.

Background: Prepartum and postpartum maternal symptoms of stress, anxiety and depression are likely to influence the child's sensory processing through hormonal alterations and an influence on mother-child interactions.

Objective: We investigated the associations between maternal prepartum and postpartum symptoms of depression, anxiety and stress related to the COVID-19 pandemic and childhood sensory avoidance at 18 months.

Methods: Longitudinal data from 409 participants followed during the COVID-19 pandemic were used.

Health Canada advisory impacts on the prevalence of oral codeine use in the Pediatric Canadian population: comparative study across provinces.

Health Canada (HC) has, since 2013, issued safety alerts restricting the use of codeine-containing drugs among breastfeeding women and children/adolescents under 18 years of age. These products are linked to breathing problems among ultra-rapid CYP2D6 metabolizers and early use of opioid can lead to future opioid misuse. Using a multi-province population-based cohort study, we estimate the impact of federal safety alerts on annual rates of codeine use in the Canadian pediatric population.

Maternal Mental Health in Pregnancy and Its Impact on Children's Cognitive Development at 18 Months, during the COVID-19 Pandemic (CONCEPTION Study).

Background: The COVID-19 pandemic has significantly affected the mental health of pregnant persons.

Objective: We aimed to evaluate the impact of maternal mental health and antidepressant use on children's cognitive development.

Methods: We followed a cohort of children born during the COVID-19 pandemic.

The use of copper as plant protection product contributes to environmental contamination and resulting impacts on terrestrial and aquatic biodiversity and ecosystem functions.

Copper-based plant protection products (PPPs) are widely used in both conventional and organic farming, and to a lesser extent for non-agricultural maintenance of gardens, greenspaces, and infrastructures. The use of copper PPPs adds to environmental contamination by this trace element. This paper aims to review the contribution of these PPPs to the contamination of soils and waters by copper in the context of France (which can be extrapolated to most of the European countries), and the resulting impacts on terrestrial and aquatic biodiversity, as well as on ecosystem functions.

Tumour necrosis factor inhibitors and serious infections in reproductive-age women and their offspring: a narrative review.

Tumour necrosis factor inhibitors (TNFi) are commonly used to treat patients with chronic inflammatory diseases, and function by inhibiting the pro-inflammatory cytokine tumour necrosis factor-α (TNF-α). Although beneficial in reducing disease activity, they are associated with an increased risk of serious infections. Data on the risk of serious infections associated with TNFi use during the reproductive years, particularly in pregnancy, are limited.

Improved assessment of the impacts of plant protection products on certain soil ecosystem services requires better consideration of terrestrial microalgae and cyanobacteria.

There is growing scientific and societal consciousness that the environmental risks and impacts of plant protection products (PPPs) cannot be properly assessed without considering ecosystem services. However, the science on this issue remains incomplete and fragmented, as recently illustrated in a collective scientific assessment that pointed out the limited knowledge on the risks and impacts of PPPs on soil ecosystem services, which are clearly overlooked. Beside soil ecosystem services, certain key players involved in these services are largely overlooked in the scientific literature on the risks and impacts of PPPs, namely soil microbial photosynthetic communities.

The impact of prenatal maternal mental health during the COVID-19 pandemic on birth outcomes: two nested case-control studies within the CONCEPTION cohort.

Objective: Assess the association between prenatal mental health during the COVID-19 pandemic and preterm birth (PTB; delivery < 37 weeks gestation) and low birth weight (LBW; < 2500 g).

Methods: Pregnant individuals, > 18 years, were recruited in Canada and provided data through a web-based questionnaire. We analyzed data on persons recruited between 06/2020 and 08/2021 who completed questionnaires while pregnant and 2 months post-partum.

Linking ecotoxicological effects on biodiversity and ecosystem functions to impairment of ecosystem services is a challenge: an illustration with the case of plant protection products.

There is growing interest in using the ecosystem services framework for environmental risk assessments of chemicals, including plant protection products (PPPs). Although this topic is increasingly discussed in the recent scientific literature, there is still a substantial gap between most ecotoxicological studies and a solid evaluation of potential ecotoxicological consequences on ecosystem services. This was recently highlighted by a collective scientific assessment (CSA) performed by 46 scientific experts who analyzed the international science on the impacts of PPPs on biodiversity, ecosystem functions, and ecosystem services.

Causality assessment of adverse drug reaction: A narrative review to find the most exhaustive and easy-to-use tool in post-authorization settings.

Background: The core motive of pharmacovigilance is the detection and prevention of adverse drug reactions (ADRs), to improve the risk-benefit balance of the drug. However, the causality assessment of ADRs remains a major challenge among clinicians, and none of the available tools of causality assessment used for assessing ADRs have been universally accepted.

Objective: To provide an up-to-date overview of the different causality assessment tools.

Capturing sex-specific and hypofertility-linked effects of assisted reproductive technologies on the cord blood DNA methylome.

Background: Children conceived through assisted reproduction are at an increased risk for growth and genomic imprinting disorders, often linked to DNA methylation defects. It has been suggested that assisted reproductive technology (ART) and underlying parental infertility can induce epigenetic instability, specifically interfering with DNA methylation reprogramming events during germ cell and preimplantation development. To date, human studies exploring the association between ART and DNA methylation defects have reported inconsistent or inconclusive results, likely due to population heterogeneity and the use of technologies with limited coverage of the epigenome.

Vaginal epithelial dysfunction is mediated by the microbiome, metabolome, and mTOR signaling.

Bacterial vaginosis (BV) is characterized by depletion of Lactobacillus and overgrowth of anaerobic and facultative bacteria, leading to increased mucosal inflammation, epithelial disruption, and poor reproductive health outcomes. However, the molecular mediators contributing to vaginal epithelial dysfunction are poorly understood. Here we utilize proteomic, transcriptomic, and metabolomic analyses to characterize biological features underlying BV in 405 African women and explore functional mechanisms in vitro.

Nonoptimal bacteria species induce neutrophil-driven inflammation and barrier disruption in the female genital tract.

Neutrophil recruitment and activation within the female genital tract are often associated with tissue inflammation, loss of vaginal epithelial barrier integrity, and increased risk for sexually transmitted infections, such as HIV-1. However, the direct role of neutrophils on vaginal epithelial barrier function during genital inflammation in vivo remains unclear. Using complementary proteome and immunological analyses, we show high neutrophil influx into the lower female genital tract in response to physiological surges in progesterone, stimulating distinct stromal, immunological, and metabolic signaling pathways.
