Background: Pregnancy/puerperium cranial venous sinus thrombosis (CVST) is rare, mainly occurring in perinatal/late pregnancy, and less frequently in early pregnancy. None has been reported after early spontaneous abortion.
Case Report: This study reports a case of CVST following early pregnancy spontaneous abortion in a patient with no known risk factors such as hypertension, diabetes, coagulopathy, or antiphospholipid syndrome. Following aggressive endovascular thrombectomy and thrombolytic treatment with 300,000 units of urokinase administered through a catheter, the patient experienced marked improvement in headache symptoms, with nausea and vomiting completely resolving. Four days later, a repeat magnetic resonance venography scan demonstrated successful recanalization of the intracranial venous sinuses, accompanied by a notable decrease in D-dimer levels upon reassessment.
Conclusion: For young patients with early pregnancy bleeding, comprehensive coagulation function and D-dimer tests could be conducted. Even after a spontaneous abortion, if the patient presents with symptoms such as headache, vomiting, or visual impairment, the possibility of pregnancy-associated CVST should be considered, and an immediate head CT or MRI should be arranged. In cases complicated by cerebral hemorrhage, endovascular thrombectomy and thrombolysis can be performed.

Maternal supplementation with α-tocopherol inhibits the development of offspring food allergy, H1R signaling and ultimately anaphylaxis early in life.

Food allergy has had a rapid rise in prevalence, and thus it is important to identify approaches to limit the development of food allergy early in life. Because maternal dietary supplementation with α-tocopherol (α-T), an isoform of vitamin E, during pregnancy and nursing increases neonate plasma levels of α-T and can limit neonate development of other allergies, we hypothesized that α-T can limit development of food allergy. To assess this, male mice with mutations in their skin barrier genes (FT-/- mice) were mated with wild-type females that received a diet supplemented with α-tocopherol or a control diet.

Congenital cytomegalovirus (cCMV) is the leading infectious cause of neonatal neurological impairment worldwide, but the viral factors enabling vertical spread across the placenta remain undetermined. The pentameric complex (PC), composed of the subunits gH/gL/UL128/UL130/UL131A, has been demonstrated to be important for entry into nonfibroblast cells in vitro. These findings link the PC to broad cell tropism and virus dissemination in vivo, denoting all subunits as potential targets for intervention strategies and vaccine development.

Background: Few studies have examined the association between lactating behaviors and postpartum weight retention (PPWR) during the 'Zuòyuèzi' period, a traditional Chinese postpartum confinement practice that typically occurs within the first month after delivery. This study aimed to examine the association between breastfeeding practices (exclusive vs. mixed feeding) and PPWR during the Zuòyuèzi period; and to explore the feasibility of the new latent category variable derived from latent class analysis (LCA) reflecting lactating experience and quality.

Unlabelled: To explore whether prenatal conditions (i.e. chorioamnionitis, preeclampsia or small-for-gestational age (SGA)) affect the very preterm infant's response to docosahexaenoic acid (DHA) on bronchopulmonary dysplasia (BPD), according to mode of delivery, an independent factor shown to modulate this association.

Importance: Maternal inflammation during pregnancy has been associated with an increased risk of neurodevelopmental disorders (NDDs), such as attention-deficit/hyperactivity disorder (ADHD) and autism, and cognitive deficits in early childhood. However, little is known about the contributions of a wider range of inflammatory proteins to this risk.
Objective: To determine whether maternal inflammatory proteins during pregnancy are associated with the risk of NDDs and executive functions (EF) in middle childhood and to identify protein patterns associated with NDDs and EF.
