Background: Neonatal sepsis remains one of the leading causes of morbidity and mortality both among term and preterm infants. Advances in neonatal care improved survival and reduced complications in preterm infants. Chemokines are chemotactic cytokines that give directional guidance for leukocyte migration during inflammatory process. The chemokine CXCL12 and its receptor CXCR4 are now known to play an important role in inflammatory states. However, its value as a biomarker in neonatal sepsis is unclear.
Objectives: To assess the value of measuring the serum levels of alpha-chemokine receptor type 4 (CXCR-4) and stromal-derived-factor-1 (CXCL12) in diagnosis of late onset neonatal sepsis.
Subject And Methods: Serum levels of CXCL12 and CXCR4 were determined in 38 full term neonates, 23 cases of late onset sepsis (13 males and 10 female), and 15 healthy neonates as control (six males and nine females) by ELISA technique and flow-cytometry.
Results: Serum levels of CXCR4 and CXCL12 were significantly higher in neonates with late onset sepsis compared with the non-septic ones. The sensitivity, the specificity, and the overall accuracy of CXCL12 were 100%. The sensitivity of CXCR4 was 87%; the specificity was 80% and the overall accuracy was 84%.
Conclusions: Serum CXCR4 and CXCL12 levels increase significantly in septic neonates and they are valuable marker in diagnosis of neonatal sepsis. Serum concentrations of both chemokines represent promising novel biomarkers for neonatal sepsis.

Background: Cesarean hysterectomy for placenta accreta spectrum disorder may be associated with severe hemorrhage because of placental invasion of the myometrium and the uterovesical space or parametrium. It leads to serious complications, such as massive hemorrhage requiring massive transfusion, coagulopathy, bladder and ureteric injuries, need for intensive care unit admission and prolonged hospital stay. To reduce the complications of cesarean hysterectomy for placenta accreta spectrum disorder, ongoing efforts are being made to develop different surgical approaches.

Objective: To evaluate the incidence of thin catheter surfactant administration (TCA) failure and compare short and long-term neonatal outcomes who failed TCA or did not.
Design: Single-center retrospective cohort study. Infants between 25 and 30 weeks of gestational age with respiratory distress syndrome and receiving 200 mg/kg poractant alfa via thin catheter administration were included.

Neonatal sepsis, a severe infection in newborns, remains one of the leading causes of morbidity and mortality among preterm infants. This study aimed to investigate the distribution of pathogens responsible for early-onset sepsis (EOS) and late-onset sepsis (LOS), the annual variability of pathogens responsible for each type of infection, and potential trends in their profiles in preterm infants from a tertiary care neonatal intensive care unit over a ten-year period. We analyzed 177 episodes of confirmed bloodstream infection between 1 January 2014 and 31 December 2023.

Sepsis is a risk factor associated with increasing neonatal morbidity and mortality, acute lung injury, and chronic lung disease. While stem cell therapy has shown promise in alleviating acute lung injury, its effects are primarily exerted through paracrine mechanisms rather than local engraftment. Accumulating evidence suggests that these paracrine effects are mediated by mesenchymal stem cell (MSC)-derived small extracellular vesicles (sEVs), which play a critical role in immune system modulation and tissue regeneration.
