Approximately 8-42% of premature infants with chronic lung disease of prematurity, bronchopulmonary dysplasia (BPD), develop pulmonary hypertension (PH). Infants with BPD-PH carry alarmingly high mortality rates of up to 47%. Effective PH-targeted pharmacotherapies are desperately needed for these infants. Although many PH-targeted pharmacotherapies are commonly used to treat BPD-PH, all current use is off-label. Moreover, all current recommendations for the use of any PH-targeted therapy in infants with BPD-PH are based on expert opinion and consensus statements. Randomized Control Trials (RCTs) are needed to determine the efficacy of PH-targeted treatments in premature infants with or at risk of BPD-PH. Prior to performing efficacy RCTs, studies need to be conducted to obtain pharmacokinetic, pharmacodynamic, and safety data for any pharmacotherapy used in this understudied and fragile patient population. This review will discuss current and needed treatment strategies, identify knowledge deficits, and delineate both challenges to be overcome and approaches to be taken to develop effective PH-targeted pharmacotherapies that will improve outcomes for premature infants with or at risk of developing BPD-PH.

Ethical considerations regarding the treatment of extremely preterm infants at the limit of viability: a comprehensive review.
Eur J Pediatr
January 2025
Neonatal Research Network of Japan, Shinjuku, Tokyo, 163-1030, Japan.
Advancements in perinatal care have improved survival rates of extremely preterm infants born at 22 to 23 weeks of gestation, thus introducing new ethical challenges associated with their treatment. Therefore, we reviewed the epidemiological prognosis, treatment evolution, and ethical considerations associated with the care of preterm infants at the limit of viability. We comprehensively searched PubMed to find relevant English-language articles published between January 2014 and July 2024.

Department of Biochemistry, School of Medicine, Babol University of Medical Sciences, Babol, Iran.
Background: This study examined the effects of yoga-based educational interventions on the volume and composition of breast milk in premature infants' mothers admitted to the neonatal intensive care unit (NICU).
Materials And Methods: A randomized controlled trial was conducted on 78 primiparous mothers whose premature infants were less than 34 weeks and were hospitalized in the NICU of Ayatollah Rouhani Hospital from February 2021 to November 2022. Mothers were assigned to a control group and an experimental group, that is, yoga, using the block randomization method.
Association between body mass index at birth and neonatal health outcomes in preterm infants: A retrospective analysis.
Pediatr Obes
January 2025
Department of Neonatology, The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University, Wenzhou, China.
Background: Studies on how birth body mass index (BMI) affects health outcomes in preterm infants are relatively limited.
Aim: To analyze the association between BMI at birth and neonatal health outcomes in extremely low and very low birth weight preterm infants in China.
Methods: Used data from the Chinese Premature Infant Informatization Platform (2022-2023).
Ileo-ileal intussusception and necrotising enterocolitis after indomethacin exposure masquerading clinically as solitary intestinal perforation.
BMJ Case Rep

Department of Paediatric Surgery, KK Women's and Children's Hospital, Singapore.
We report a case of small bowel perforation from ileo-ileal intussusception with necrotising enterocolitis (NEC) after indomethacin exposure mimicking spontaneous intestinal perforation in an extremely preterm neonate. Indomethacin exposure can cause mesenteric hypoperfusion, resulting in an ischaemic lead point for intussusception and NEC. We advocate that intussusception should be considered as one of the differentials for neonates with recurrent feeding intolerance postindomethacin exposure.

Department of Medical Sciences, Cancer Epidemiology Unit, University of Turin and CPO-Piemonte, Turin, Italy.
Objectives: Maternal occupational exposures during early pregnancy can be detrimental to foetus health and have short- and long-term health effects on the child. This study examined their association with adverse birth outcomes.
Methods: The study included 3938 nulliparous women from the Italian NINFEA mother-child cohort.
