Abstract Background: In preeclampsia, the neurologic symptoms, especially a lingering headache, can sometimes mimic more severe intracranial conditions, pushing doctors to quickly consider early delivery. Obstructive hydrocephalus during pregnancy is an uncommon but tricky diagnosis, one that could easily be missed when hypertension and proteinuria are already present, potentially delaying the identification of a neurosurgical emergency.

Abstract Background: Using data from the Lanzhou Birth Cohort in China, this study examined the associations between prenatal exposure to vanadium (V) and lead (Pb)—both individually and jointly—and the risk of neonatal congenital heart defects (CHDs). Methods: This birth cohort study, conducted in Lanzhou, China, included 97 mother-newborn pairs assigned to the case group and 194 pairs serving as controls (1:2 ratio).
