Background: Reproductive failure is a significant public health concern. Although relatively little is known about factors affecting fertility and early pregnancy loss, a growing body of literature suggests that environmental and lifestyle factors play an important role. There is sufficient evidence to hypothesize that diet, particularly its constituent antioxidants, and oxidative stress (OS) may influence the timing and maintenance of a viable pregnancy. We hypothesize that conditions leading to OS in the female affect time-to-pregnancy and early pregnancy loss.
Methods: We review the epidemiology of female infertility related to antioxidant defenses and oxidation and examine potential sources of OS from the ovarian germ cell through the stages of human pregnancy and pregnancy complications related to infertility. Articles were identified through a search of the PubMed database.
Results: Female OS is a likely mediator of conception and threshold levels for OS exist, dependent on anatomic location and stage of preconception.
Conclusions: Prospective pregnancy studies with dietary assessment and collection of biological samples prior to conception with endpoints of time-to-pregnancy and early pregnancy loss are needed.

Background: The dynein cytoplasmic two heavy chain 1 (DYNC2H1) gene encodes a cytoplasmic dynein subunit. Cytoplasmic dyneins transport cargo towards the minus end of microtubules and are thus termed the "retrograde" cellular motor. Mutations in DYNC2H1 are the main causative mutations of short rib-thoracic dysplasia syndrome type III with or without polydactyly (SRTD3).

Background: Aortic dissection occurs rarely during pregnancy but carries a significantly high vital risk for both the mother and the fetus. Early diagnosis and treatment are critical for a successful outcome.
Case Presentation: A 32-year-old pregnant woman at 31 weeks of gestation began experiencing shortness of breath, chest pain, and palpitations, which were attributed to an anxiety disorder she had been previously diagnosed with.

Background: Recurrent early pregnancy loss [rEPL] is a traumatic experience, marked by feelings such as grief and depression, and often anxiety. Despite this, the psychological consequences of rEPL are often overlooked, particularly when considering future reproductive health or approaching subsequent pregnancies. The SARS-CoV-2 pandemic led to significant reconfiguration of maternity care and a negative impact on the perinatal experience, but the specific impact on women's experience of rEPL has yet to be explored.

An unusual case of small bowel obstruction (SBO) due to haemostatic gelatin sponge placed during caesarean delivery is presented. A primigravida in their 30s underwent caesarean delivery at 39 weeks, and developed symptoms of SBO from the second postoperative day. Given the worsening condition of the patient and increasing abdominal girth, CT of the abdomen and pelvis was done which revealed features of SBO.

Reduced trophoblast migration and invasion contribute to unexplained recurrent spontaneous abortion (URSA). Aquaporin 3 (AQP3) plays a crucial role in facilitating trophoblast migration and invasion during early pregnancy through fetal-maternal crosstalk. This study aimed to comprehensively investigate the mechanism involving AQP3 and its modulatory effects on human extravillous trophoblast (HTR-8/SVneo cells) migration and invasion.
