Study Design: Fifty-four children from the BrainChild Longitudinal Study completed 2 study visits 2 years apart, in which fasting blood draws were collected, and children wore wrist-accelerometers for 7-days. Isotemporal substitution modeling was used to evaluate the impact of reallocating 30 minutes of sedentary time with other movement behaviors (light-activity, moderate-physical-activity, vigorous-physical-activity, and sleep) on changes in cardiometabolic outcomes (body mass index, body-fat percent, systolic blood pressure, diastolic blood pressure, fasting insulin, fasting c-peptide, and insulin resistance) over 2-years adjusted for child age, sex, and puberty.
Background: Autism spectrum disorder (ASD) prevalence has risen steadily in California (CA) over several decades, with environmental factors like air pollution (AP) increasingly implicated. This study investigates associations between prenatal exposure to both criteria AP and traffic-related air toxics and ASD risk for 1990-2018 births.
Methods: Utilizing CA Department of Public Health birth registry data from 1990 to 2018, linked with ASD diagnoses from the CA Department of Developmental Services (n = 13,591,003 children; ASD cases = 138,460, identified from birth year through 2022, allowing for a follow-up ranging from a minimum of 4 to a maximum of 32 years) we assessed prenatal exposure to PM, NO, O, and six traffic-related air toxics (benzene, 1,3-butadiene, chromium, lead, nickel, zinc) using machine learning-enhanced land-use regression models.
Background: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder with increasing prevalence. While genetics play a strong causal role, among environmental factors, air pollution (AP) exposure in pregnancy and infancy has been strongly endorsed as a risk factor. However, potential multigenerational impacts through the exposure of the grandmother during her pregnancy remain unexplored.

Purpose: This study aims to assess rates of COVID-19 exposure during pregnancy among children born during the original, Delta and Omicron waves, and to identify potential disparities.
Methods: This birth cohort includes 125,152 children born from 3/1/2020 to 2/28/2023 in southern California. Data on maternal COVID-19 infection, demographics, and health status were extracted from electronic medical records.
Background: We previously assessed associations of prenatal exposure to fine particulate matter (PM) tracers reflecting tailpipe (elemental carbon [EC] and organic carbon [OC]) and non-tailpipe emissions (copper [Cu], iron [Fe] and manganese [Mn]) with risk of autism spectrum disorder (ASD) in a large pregnancy cohort. To address genetic and family environment confounding, we conducted an ASD-discordant sibling study.
Methods: Data included 4024 children (1837 with and 2187 siblings without ASD) born to 1801 unique mothers who had at least one child diagnosed with ASD by age 5, and one child without ASD.
Background: The alarming rate of bacterial resistance has urged for vigorous antibiotic de-escalation cultures worldwide. However, the art of de-escalation remains challenging as most clinicians have the fear or stigma that antibiotic de-escalation is strongly associated with higher mortality. This study aimed to determine the factors strongly correlated with higher mortality rates after antibiotic de-escalation and possibly serve as a benchmark study for developing a validated antibiotic de-escalation tool in the near future.

Given that fine and ultrafine particles can be highly correlated due to shared emission sources, challenges remain to distinguish their health effects. In a retrospective cohort of 318,371 mother-child pairs (4549 ASD cases before age 5) in Southern California, pregnancy average PM and PM were estimated using a California-based chemical transport model and assigned to residential addresses.

Background: Maternal preeclampsia is associated with a risk of autism spectrum disorders (ASD) in offspring. However, it is unknown whether the increased ASD risk associated with preeclampsia is due to preeclampsia onset or clinical management of preeclampsia after onset, as clinical expectant management of preeclampsia allows pregnant women with this complication to remain pregnant for potentially weeks depending on the onset and severity. Identifying the risk associated with preeclampsia onset and exposure provides evidence to support the care of high-risk pregnancies and reduce adverse effects on offspring.
