Study Question: Does exposure to particulate matter (PM) air pollution prior to oocyte retrieval or subsequent frozen embryo transfer (FET) affect the odds of live birth?
Summary Answer: Live birth rates are lower when particulate matter (PM2.5 and PM10) levels are higher prior to oocyte retrieval, regardless of the conditions at the time of embryo transfer.
What Is Known Already: Exposure to air pollution is associated with adverse reproductive outcomes, including reduced fecundity and ovarian reserve, and an increased risk of infertility and pregnancy loss.
Quasi-periodic eruptions (QPEs) are luminous bursts of soft X-rays from the nuclei of galaxies, repeating on timescales of hours to weeks. The mechanism behind these rare systems is uncertain, but most theories involve accretion disks around supermassive black holes (SMBHs) undergoing instabilities or interacting with a stellar object in a close orbit. It has been suggested that this disk could be created when the SMBH disrupts a passing star, implying that many QPEs should be preceded by observable tidal disruption events (TDEs).

Objectives: Report the gestation-specific risk of perinatal mortality at term.
Methods: Population-based cohort study using linked health data to identify all singleton births at gestations 37-41 weeks, in Western Australia (WA) from 2009 to 2019.
Effects of a live versus heat-inactivated probiotic spp in preterm infants: a randomised clinical trial.
Arch Dis Child Fetal Neonatal Ed

Background: Heat-inactivated probiotics (HPs) may provide an effective alternative to live probiotics (P) by avoiding their risks (eg, probiotic sepsis) while retaining the benefits. We assessed the safety and efficacy of a HP in very preterm (VP: gestation <32 weeks) infants.
Methods: VP infants were randomly allocated to receive a HP or P mixture ( M-16V, subsp.
Article Synopsis
- - Neonatal sepsis is a serious condition leading to high mortality and morbidity, particularly affecting low and middle-income countries, while late-onset sepsis (LOS) still impacts a notable percentage of infants in high-income countries.
- - A study at King Edward Memorial Hospital analyzed data from over 23,000 newborns, finding 370 sepsis episodes; predominant causes for early-onset sepsis were Streptococcus agalactiae and Escherichia coli, whereas coagulase-negative staphylococci and E. coli were the main culprits for LOS, which decreased in incidence over the study period.
- - Infants with sepsis faced significantly worse health outcomes, including higher mortality rates, longer hospital stays, and
