Objective: To study the effects of meconium-stained amniotic fluid on the cord blood IgE level in neonates.
Methods: A total of 404 neonates with meconium-stained amniotic fluid who were born by cesarean delivery between August 2003 and August 2005 (meconium-stained group) and 256 neonates with normal amniotic fluid delivered by cesarean (control group) were enrolled in this study. The meconium-stained group consisted of 80 cases of mild, 62 cases of moderate and 262 cases of severe meconium-stained amniotic fluid. The cord blood IgE level was measured using ELISA.
Results: The cord blood IgE level in the meconium-stained group was statistically higher than that in the control group (t = 4.03, P < 0.01). There were significant differences between the mild and severe meconium-stained subgroups and the control group for the cord blood IgE level (F=4.28, P < 0.01). The cord blood IgE level in neonates with premature rupture of the membrane between the meconium-stained and the control groups was statistically different. Sexes, gestational age, birth weight and birth order were not associated with the IgE level of cord blood.
Conclusions: The cord blood IgE levels in neonates with meconium-stained amniotic fluid increase. Premature rupture of the membranes may be associated with an increase of cord blood IgE level.

Spinal cord injury (SCI) is a critical condition affecting the central nervous system that often has permanent and debilitating consequences, including secondary injuries. Oxidative damage and inflammation are critical factors in secondary pathological processes. Selenium nanoparticles have demonstrated significant antioxidative and anti-inflammatory properties via a non-immunosuppressive pathway; however, their clinical application has been limited by their inadequate stability and functionality to cross the blood-spinal cord barrier (BSCB).

Background: Pacific Biosciences (PacBio) circular consensus sequencing (CCS), also known as high fidelity (HiFi) technology, has revolutionized modern genomics by producing long (10 + kb) and highly accurate reads. This is achieved by sequencing circularized DNA molecules multiple times and combining them into a consensus sequence. Currently, the accuracy and quality value estimation provided by HiFi technology are more than sufficient for applications such as genome assembly and germline variant calling.

Background: Preeclampsia significantly impacts maternal and perinatal health. Early screening using advanced models and primary prevention with low-dose acetylsalicylic acid for high-risk populations is crucial to reduce the disease's incidence. This study assesses the feasibility of implementing preterm preeclampsia screening and prevention by leveraging information from our current aneuploidy screening program in a real-world setting with geographic separation clinical site and laboratory analysis site.

Cell therapies as treatments for neonatal conditions have attracted significant research and parent interest over the last two decades. Mesenchymal stromal cells, umbilical cord blood cells and neural stem cells translate from lab, to preclinical and into clinical trials, with contributions being made from all over the world. Effective and timely translation involves frequent reflection and consultation from research-adjacent fields (i.

Background: Placenta Accreta Spectrum (PAS) disorders has been reported to be associated with a maternal mortality rate of 7-10%, worldwide, and many women who survive, experience life changing morbidity. Triple P procedure (- perioperative placental localization and incision on the myometrium above the upper border of the placenta; - pelvic devascularisation; and -placental non-separation and myometrial excision) was developed in 2010 as a novel conservative alternative to peripartum hysterectomy to avoid severe maternal morbidity and mortality). There have been several modifications to the original Triple P Procedure to achieve "pelvic devascularisation" based on locally available resources.
