Preterm infants are most vulnerable to pertussis. Whether they might benefit from maternal immunization is unknown. Extending our previous results in term neonates, this observational study demonstrates that second- rather than third-trimester maternal vaccination results in higher birth anti-pertussis toxin titers in preterm neonates.

Effect of freezing and thawing on ejaculated sperm and subsequent pregnancy and neonatal outcomes in IVF.

Front Endocrinol (Lausanne)

December 2024

Department of Assisted Reproduction, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China.

Background: Techniques for sperm cryopreservation have exhibited their potential in male fertility preservation. The use of frozen-thawed sperm in fertilization (IVF) cycles is widespread today. However, many studies reported that cryopreservation might have adverse effects on sperm DNA integrity, motility, and fertilization, probably due to cold shock, intra- and extracellular ice crystals, and excess reactive oxygen species (ROS).

Background: Intravenous lipid emulsions are an essential component of nutritional support for very preterm infants. Many neonatal intensive care units have transitioned from traditional soybean oil-only to fish oil-containing multicomponent lipid emulsions, but the neurodevelopmental implications have not been well-explored. The primary aim of this study was to assess extrauterine third trimester brain growth in very preterm infants supported with soybean oil-only compared to fish-oil containing multicomponent lipid emulsions; white matter development and neurobehavioral regulation at term were also investigated.

Maternal and neonatal outcomes following resuscitative hysterotomy for out of hospital cardiac arrest: a systematic review.

Resuscitation

December 2024

University Hospitals Birmingham NHS Foundation Trust, Birmingham Heartlands Hospital B9 5SS UK; Warwick Clinical Trials Unit, University of Warwick, Coventry, CV4 7AL.

Objective: To examine maternal and neonatal outcomes following Resuscitative Hysterotomy for out of hospital cardiac arrest (OHCA) and to compare with timing from cardiac arrest to delivery.

Methods: The review was registered with PROSPERO (CRD42023445064). Studies included pregnant women with out of hospital cardiac arrest and resuscitative hysterotomy performed (in any setting) during cardiac arrest.

Background: Neonatal sepsis continues to be a leading cause of mortality among the NICU admitted neonates. The most common causative organisms have been proven to be hospital-acquired organisms.

Aims And Objectives: This study was planned with aim of understanding the pathological colonization of neonatal skin and associated risk factors as well as finding a possible correlation between blood culture isolates and neonatal skin colonizers and their antimicrobial resistance patterns.

Antenatal corticosteroids (ACS) are widely used to reduce respiratory distress syndrome (RDS) in preterm neonates, enhancing neonatal outcomes. However, the potential effects of ACS on other aspects of neonatal health, such as cortisol levels and glucose regulation, remain a concern. This study examines whether ACS administration impacts cortisol and glucose homeostasis in preterm infants by analyzing data from 14 selected studies.
