Objective: Our objective was to determine if early pregnancy urinary metabolomic profiles could predict fetal adiposity and macrosomia.
Methods: This is a prospective study of 50 healthy women in their second pregnancy. Fasting urine samples taken during early pregnancy were analyzed using NMR spectroscopy. Maternal glucose and insulin were measured in early pregnancy and at 28 weeks and the HOMA index for insulin resistance calculated. At 34 weeks ultrasound assessed fetal anthropometry including fetal anterior abdominal wall width (AAW). At delivery birth weight was recorded. Probabilistic principal component with covariates analysis (PPCCA), a novel extension of principal component analysis, which facilitates joint modeling of metabolomic data and additional covariate information, was employed to analyze the data.
Results: This analysis revealed that maternal HOMA and AAW significantly covaried with the (1)H NMR derived metabolomic profile of the urine. As such, in this cohort of healthy, non-diabetic women, early pregnancy urinary metabolomic profile differed significantly according to both maternal insulin resistance and fetal fat deposition in utero.
Conclusion: These findings hold potential for early pregnancy identification of those at risk of fetal macrosomia.

This study presents the construction of a comprehensive spatiotemporal atlas of white matter tracts in the fetal brain for every gestational week between 23 and 36 wk using diffusion MRI (dMRI). Our research leverages data collected from fetal MRI scans, capturing the dynamic changes in the brain's architecture and microstructure during this critical period. The atlas includes 60 distinct white matter tracts, including commissural, projection, and association fibers.

Preterm births constitute a major public health issue and a chronic, cross-generational condition globally. Psychological and biological factors interact in a way that women from low socio-economic status (SES) are disproportionally affected by preterm delivery and at increased risk for the development of perinatal mental health problems. Low SES constitutes one of the most evident contributors to poor neurodevelopment of preterm infants.

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) results from maternal antibodies targeting fetal platelets during pregnancy, often causing hemorrhagic manifestations detectable antenatally or shortly after birth. We report an atypical form of FNAIT with delayed onset in a healthy, breastfed male infant who developed diffuse petechiae 2 weeks after birth due to severe thrombocytopenia. The mother was shown to be negative for the human platelet antigen-1a (HPA-1a) allele but had anti-HPA-1a IgG antibodies, while the father and newborn were HPA-1a positive, confirming the diagnosis.

Importance: Upper gastrointestinal cancers such as gastric and esophageal cancers are rare malignancies with poor prognosis because it is usually diagnosed in latter stages. Presenting symptoms are frequently presumed pregnancy related rather than malignancy related. This review will raise awareness to consider these aggressive cancers in evaluating gastrointestinal complaints during pregnancy.

Problem: Hashimoto's disease is the commonest autoimmune disease of pregnancy. The presence of Anti-Thyroid antibodies (ATAs) alone [subclinical hypothyroidism] has also been shown to have adverse pregnancy effects. These can result in failure to conceive, recurrent miscarriages, anemia, preeclampsia, and abruption.
