Objective: To provide an overview of the observational studies on child's cognitive, linguistic, and educational outcomes following prenatal exposure to psychotropics and analgesics, including reporting of outcome measure validity and reliability.
Study Design: We searched four databases, MEDLINE, Embase, PsycINFO, and PubMed from inception to September 2023. We included all original studies involving participants less than 18 years old, who were prenatally exposed to psychotropics and/or analgesics with cognitive, linguistic, and/or educational outcomes and excluded those lacking comparison groups.
Results: 80 studies were identified. Most studies (47%) focused on the effects of prenatal exposure to antiepileptics on child cognition. Valproate was consistently associated with an increased risk of neurodevelopmental disorders, whereas the results for other medications were sparse and conflicting. Neurodevelopmental outcomes were measured by psychometric assessments in 71 studies and by diagnostic codes in health care registries in nine studies. Only 33 of the 71 studies (46.5%) using psychometric measures mentioned the psychometric properties of the instruments used. In studies using diagnostic outcome measures, only one study reported positive predictive values and performed a sensitivity analysis to address outcome misclassification.
Conclusion: Except for valproate, there is a concerning lack of studies on the impact of prenatal exposure to psychotropics and analgesics on cognitive, linguistic, and educational outcomes with existing studies yielding inconsistent findings. Regardless of whether psychometric measures or diagnostic codes were used, most studies lacked a robust assessment of outcome measures, which threatens their validity and interpretability. Future studies on long-term prenatal medication safety need to focus on the accuracy of neurodevelopmental outcome measures.

Background: Congenital syphilis (CS) in the United States increased 10-fold in the last decade. At a large public hospital in Los Angeles, the numbers of infants born to birthing parents with untreated syphilis during pregnancy have continued to rise.
Methods: We compiled a retrospective case-series from all infant rapid plasma reagin (RPR) test results from 2022-2023 summarizing CS diagnosis and relevant diagnostic criteria.

The rising incidences of chronic kidney disease (CKD) and renal failure are a major public health concern. Arsenic, a widespread water contaminant and environmental toxicant, is well-known to contribute to kidney disease in adults. However, its long-term effects on kidney health following early-life exposure remain poorly understood.

Introduction: Household disinfectants and cleaning products (HDCPs), which involve a complex mixture of chemical ingredients, are commonly used in homes. HDCPs significantly contribute to chemical exposure in the indoor environment by releasing particles and volatile organic compounds while being used, potentially harming the respiratory health of those exposed.
Areas Covered: We provide an overview of scientific literature, especially from the last five years, regarding the (i) effects of using of HDCPs on adults' respiratory health; (ii) associations between prenatal or childhood exposure to HDCPs and children respiratory health.
Resveratrol Alleviates the Prenatally Intermittent Hypoxia-Induced Cognitive Impairment in Male Offspring Mice Through Modulating the SIRT1/HIF-1α Pathway.

Objective: Growing evidence indicate that prenatal intermittent hypoxia (PIH) exposure can have an impact on the critical brain nerve development of the fetus, resulting in cognitive deficits in the offspring mice. Resveratrol, recognized for its anti-inflammatory and antioxidant capabilities, has potential to ameliorate synaptic dysfunction, which in turn may contribute to its positive influence on cognitive impairment. Nevertheless, the precise manner in which resveratrol mitigates cognitive deficits stemming from maternal hypoxia remains to be fully elucidated, including the specific mechanisms at play.

Extremely preterm birth predisposes infants to bronchopulmonary dysplasia and associated pulmonary hypertension (PH). High altitude exposure during pregnancy has also been shown to worsen infant lung and pulmonary vascular outcomes. Animal models addressing the mechanisms for how maternal hypoxia impacts postnatal and adult lung and pulmonary vascular outcomes are lacking and development of a model to address this gap would enable new mechanistic studies.
