Aim: To determine whether infants with intrauterine drug exposure (IUDE) are similarly at risk for cerebral palsy (CP) as other high-risk populations, whether CP classification differs based on IUDE status, and describe the association of CP with specific substances among exposed infants.
Method: This was a retrospective analysis of infants in a high-risk follow-up program (n=5578) between January 2014 and February 2018 with a history of IUDE or who received a CP diagnosis. CP rates were compared using two-sample z-tests. CP classification was assessed using Fisher's exact, Cochran-Armitage, and Wilcoxon rank-sum tests. Models for CP risk were assessed using multivariable logistic regression.
Results: Among all infants with IUDE (n=1086), 53.8% were male with a mean (SD) birth gestational age of 36.8 (3.6) weeks. Among unexposed infants with CP (n=259), 54.4% were male with a mean (SD) birth gestational age of 29.9 (5.7) weeks. Opioids were the most common exposure (93.7%) of all infants with IUDE. The CP rate in the IUDE (5.2%) and unexposed (5.7%) high-risk populations were not significantly different (p=0.168), nor were there differences in CP typology, topography, or severity between exposed (n=57) and unexposed (n=259) infants (all p>0.05). In patients with IUDE and after controlling for established CP risk factors, the observed odds of CP varied among substances.
Interpretation: We suggest that IUDE should be considered a 'newborn-detectable risk' in the guidelines for the early detection of CP.

Gestational diabetes mellitus (GDM) significantly disrupts placental structure and function, leading to complications such as intrauterine growth restriction (IUGR) and preeclampsia. This study aimed to investigate the effects of GDM on placental histology, angiogenesis, and oxidative stress, as well as evaluate metformin's protective role in mitigating these changes. A total of 60 pregnant Sprague-Dawley rats were divided into four groups: control, metformin-treated, GDM, and GDM with metformin.

Background: Cornelia de Lange syndrome (CdLS) is a multisystem genetic disorder. Although individuals with variants in the SMC1A gene are less commonly seen in CdLS, they exhibit a high incidence of epilepsy and atypical phenotypic variability.
Methods: The clinical data of a patient with non-classic CdLS and epilepsy caused by an SMC1A variant were summarized.

Aim: This study aimed to evaluate the effect of maternal vitamin D use during intrauterine life on fetal bone development using ultrasonographic image processing techniques.
Materials And Methods: We evaluated 52 pregnant women receiving vitamin D supplementation and 50 who refused vitamin D supplementation. Ultrasonographic imaging was performed on the fetal clavicle at 37-40 weeks of gestation.

Nicotine is one of the most toxic substances found in cigarettes, but also found in chewing tobacco gum, patches and vaping products (electronic cigarettes). In addition to being a highly addictive chemical, it is capable of reducing fertility in men and women. In the ovaries, it can induce morphological changes and impair the formation of follicles, being a possible cause of changes in the reproductive cycle and anticipation of menopause in women whose mothers smoked during pregnancy.

Background: Isoproterenol (ISO) is a nonselective beta-adrenergic receptor agonist known for its vasodilatory effects. This experiment aims to investigate whether intrauterine ISO administration could alter vascular indices and follicular development in postpartum Holstein cows.
Objectives: The objectives are to evaluate the effects of intrauterine ISO administration on vascular changes and its impact on follicular development compared to placebo groups.
