Fetal alcohol spectrum disorders (FASD) is an umbrella term which covers a wide range of deficits in prenatal and postnatal growth, anatomy and CNS functions produced by prenatal alcohol exposure. The most severe form of FASD is fetal alcohol syndrome (FAS) characterized by additional specific craniofacial and brain malformations. Despite a high prevalence and extensive clinical studies, the fundamental mechanisms of FASD are still poorly understood. Thereby, experimental models, which allow better control for both socio-environmental and genetic factors, are critical to our understanding of FASD. The review is focused on the effects of exposure to alcohol during the prenatal period in animal models. The authors outline that prenatally alcohol-induced changes in motor and executive functions, learning and memory, stress reactivity and affective state are remarkably parallel between animals and humans. Finally, the authors consider a potential impact of postnatal social and environmental factors on the outcome in experimental models of FASD.

The pace of biological aging varies between people independently of chronological age and mitochondria dysfunction is a key hallmark of biological aging. We hypothesized that higher functional impact (FI) score of mitochondrial DNA (mtDNA) variants might contribute to premature aging and tested the relationships between a novel FI score of mtDNA variants and epigenetic and biological aging in young adulthood. A total of 81 participants from the European Longitudinal Study of Pregnancy and Childhood (ELSPAC) prenatal birth cohort had good quality genetic data as well as blood-based markers to estimate biological aging in the late 20.

Rationale: Microcephaly, epilepsy, and developmental delay (MCSZ) is a rare neurodevelopmental disorder associated with autosomal recessive inheritance of mutations in the polynucleotide kinase 3'-phosphatase (PNKP) gene. Prompt identification and management are essential, as delayed diagnosis or intervention may result in severe complications or mortality. In this case, prenatal screening in the second trimester detected fetal microcephaly with a gradual decline in head circumference, prompting the decision to terminate the pregnancy.

Background: The impacts of early-life tobacco smoke exposure, including exposure during pregnancy and the initiation of smoking during childhood and adolescence, on cognitive decline and the risk of dementia in later life have not been investigated.
Methods: We used data from the UK Biobank (UKB) to assess early-life tobacco exposure, including in utero exposure and the age at which smoking was initiated. Cox proportional-hazards regression models were employed to gauge the relationships between early-life tobacco smoke exposure and both the risk of cognitive decline and dementia in adulthood.

Objective: Prenatal alcohol and tobacco exposure continue to impact a significant portion of the US population every year. Differences in neighborhood environment may be a contributing factor. The current study examines whether prenatal alcohol and tobacco exposure differ by neighborhood environment.
