Article Abstract
Background: Previous studies have suggested that probiotics may have potential benefits for preterm infants. Their efficacy seems to depend on the particular species or combinations used.
Methods: To further investigate the effects of probiotics in preventing necrotizing enterocolitis (NEC) and other related outcomes in preterm infants, we conducted a network meta-analysis of 51 randomized controlled trials involving 11,661 participants.
Results: Our study revealed that most probiotics can effectively reduce the incidence of NEC (at or beyond Bell's stage II). Lactobacillus (RR, 0.59; 95% CI: 0.29, 0.98), the combination of Bifidobacterium and Lactobacillus (RR, 0.47; 95% CI: 0.20, 0.87), and the combination of Bifidobacterium, Lactobacillus, and Streptococcus (RR, 0.17; 95% CI: 0.00, 0.84) were the only treatments that significantly reduced all-cause mortality compared to placebo. Lactobacillus can be effective in reducing the time preterm infants spend in the hospital (MD, -4.23; 95% CI: -7.62, -0.81) and reaching full enteral feeding (MD, -2.15; 95% CI: -3.70, -0.64).
Conclusions: The combination of Bifidobacterium, Lactobacillus, and Enterococcus was the most efficacious in reducing the mortality and incidence of NEC (Bell II or above) in preterm infants. Both prebiotics and Lactobacillus alone were found to be highly effective in reducing the length of hospitalization and the time needed to achieve full enteral feeding. No evidence suggests that probiotics affect sepsis risk.
Trial Registration: The study protocol was registered with PROSPERO (CRD42023460231) on March 10, 2023.

Red blood cell transfusion frequency and the risk and severity of bronchopulmonary dysplasia in preterm infants: a retrospective cohort study.
BMC Pediatr
September 2025
Department of Neonatology, Zhangzhou Affiliated Hospital of Fujian Medical University, Zhangzhou, Fujian, China.
Background: Red blood cell (RBC) transfusion is a common intervention for anemia in preterm infants; however, its association with bronchopulmonary dysplasia (BPD) remains debated. While biological mechanisms suggest potential harm, the clinical impact of transfusion frequency on BPD incidence and severity remains unclear.
Objective: To investigate whether RBC transfusion frequency is independently associated with the risk and severity of BPD in preterm infants born before 32 weeks of gestation.

Background: Umbilical arterial catheterisation is a common intervention performed in the neonatal intensive care unit (NICU) especially in extremely preterm and extremely low birth weight neonates. Rarely catheter fracture or breakage can occur, leaving behind part of the catheter in the aorta. A handful of cases have been reported in the literature, with the majority being managed surgically.

Premature infants are at high risk for brain injuries such as intraventricular hemorrhage and periventricular white matter injury. This study applies omics technology to analyze urinary protein expression, aiming to clarify preterm brain injury mechanisms and identify therapeutic targets. Urine samples were collected from 29 very preterm infants (VPI) without brain injury and 11 with moderate/severe injury at eight time points: Days 1, 2, 3, 4, 6, 8, 28, and term-equivalent age (TEA).

Importance: Exposure to inflammation from chorioamnionitis places the fetus at higher risk of premature birth and may increase the risk of neurodevelopmental impairments, though the evidence for the latter is mixed.
Objective: To evaluate whether moderate to severe histologic chorioamnionitis (HCA) is directly associated with adverse motor performance, independent of the indirect mediating effects of premature birth.
Design, Setting, And Participants: This prospective, population-based cohort study recruited participants between September 16, 2016, and November 19, 2019, from referral and nonreferral neonatal intensive care units of 5 southwestern Ohio hospitals.
Non-invasive left ventricular myocardial work indices in preterm neonates born to mothers with severe preeclampsia in pregnancy.

Objective: The study utilized non-invasive myocardial work indices to investigate myocardial injury in infants born to mothers with severe preeclampsia (SPE) and to explore the duration of this myocardial damage during the neonatal period.
Methods: This prospective study included 34 preterm infants born to mothers with SPE and 28 preterm infants born to mothers without severe pregnancy complications (termed "controls"). Echocardiography was performed in infants within 24 h of birth, then again at 48-72 h and 14-28 days, to obtain echocardiographic parameters.
