Objective: To evaluate the relationship between umbilical artery pulsatility index and the umbilical cord pH in small-for-gestational-age fetuses.
Methods: Data were collected from all pregnancies seen in our Fetal Surveillance Unit that underwent antenatal monitoring for being small-for-gestational-age beyond 24 weeks of pregnancy. A linear regression was used to analyse the effect of the umbilical artery pulsatility index (UAPI) and umbilical artery pH at birth, assessing interaction and controlling for clinically meaningful antenatal, Doppler, biophysical and perinatal variables.
Results: A total of 117 pregnancies were included. According to the estimated model (which included all clinically significant confounders and statistically significant interactions), in cases with reactive cardiotography (CTG) a 1-unit increase in the UAPI resulted in a mean decrease of 0.021 (95% 0.05 to -0.005) units of umbilical artery pH at delivery. In the non-reactive CTG group a 1-unit increase in the UAPI resulted in a mean decrease of 0.02 (95% CI 0.059 to -0.019) units of umbilical artery pH at delivery. Finally, in fetuses with a pathological CTG a 1-unit increase in the UAPI resulted in a mean decrease of 0.149 (95% CI 0.107 to 0.19) units of umbilical artery pH at delivery.
Conclusions: The crude effect between umbilical artery velocimetry on umbilical artery pH at birth has to be interpreted with caution, since an important part of this effect is related to other factors that confound and modify the relationship. After controlling for confounders, it was only in fetuses with pathological CTG that the effect remained statistically significant.

Background: Birth asphyxia is a critical condition caused by an insufficient oxygen supply during delivery, and it poses a major threat to the health of newborns. The present meta-analysis aimed to estimate the prevalence of birth asphyxia among neonates and identify its risk factors in China.
Methods: PubMed, EMBASE, Scopus, Web of Science, the China Academic Journals (CNKI), the Chinese Biomedical Literature (CBM), the China Science and Technology Journal Database (VIP), and the WanFang database were searched for related publications.
ICAM-1 expression is upregulated in the umbilical vein endothelial cells in acute chorioamnionitis with foetal inflammatory response.

Introduction: ICAM-1 is an adhesion molecule expressed on the endothelial cells and is involved in regulating leukocyte recruitment to the site of inflammation. Elevated ICAM-1 mRNA expression was found in the serum of mothers with chorioamnionitis. This study aimed to determine the expression of ICAM-1 in the placenta and umbilical cord of pregnancy with chorioamnionitis, and its association with adverse neonatal outcome.

Diabetes mellitus is a chronic disease characterized by metabolic defects, including insulin deficiency and resistance. Individuals with diabetes are at increased risk of developing cardiovascular complications, such as atherosclerosis, coronary artery disease, and hypertension. Conventional treatment methods, though effective, are often challenging, costly, and may lead to systemic side effects.

Objective: Hypoxic-ischemic brain damage (HIBD) is a leading cause of neonatal mortality, resulting in brain injury and persistent seizures that can last into the late neonatal period and beyond. Effective treatments and interventions for infants affected by hypoxia-ischemia remain lacking. Clinical investigations have indicated an elevation of nuclear factor of activated T cells 5 (NFAT5) in whole blood from umbilical cords of severely affected HIBD infants with epilepsy.

Background: Shivering, nausea and vomiting are common complications in cesarean section during neuraxial anesthesia. The aim of this study was to investigate the effects of prophylactic use of ondansetron on intraoperative shivering, nausea and vomiting in women undergoing cesarean section.
Methods: A total of 80 full-term parturients were randomly divided into the ondansetron group and the control group.
