INTRODUCTION: There is uncertainty and lack of consensus regarding optimal management of patent ductus arteriosus (PDA). We aimed to determine current clinical practice in PDA management across a range of different regions internationally. MATERIALS AND METHODS: We surveyed PDA management practices in neonatal intensive care units using a pre-piloted web-based survey, which was distributed to perinatal societies in 31 countries. The survey was available online from March 2018 to March 2019...

OBJECTIVE: To analyze the effectiveness of cerclage in twin pregnancies with a short cervix. STUDY DESIGN: Retrospective cohort study performed in two University Institutions in Valencia (Spain) with two different protocols for the management of asymptomatic dichorionic diamniotic twin pregnancies with mid-trimester cervical length ≤ 25 mm: treatment with indomethacin, antibiotics and cerclage (cerclage group) (N = 43) versus expectant management (control group) (N = 37)...

BACKGROUND: Tissue hypoxia remains a leading cause of morbidity and mortality in preterm infants. Current biomarkers often detect irreversible hypoxic cellular injury (i.e. lactate) and are non-specific. A new biomarker is needed which detects tissue hypoxia before irreversible damage occurs. AIMS: To investigate the relation between serum ischemia modified albumin (IMA), a marker of hypoxia; and analytic variables, patient related variables and conditions associated with hypoxia, in preterm infants...

AIM: Transcatheter closure of the patent ductus arteriosus (TCPDA) is increasingly used in preterm infants as an alternative to surgical ligation. However, clinically ill preterm infants are at risk of contrast nephropathy due to the angiography contrast agents used during the procedure. METHODS: We performed a single-centre before-and-after comparative study in VLBW infants to compare the kinetics of serum creatinine during the first 4 days after TCPDA with or without angiography...

Objective Determine the risk factors of cerebellar injury in infants with surgical necrotizing enterocolitis (NEC). Methods Retrospective study compared clinical/pathological information between surgical NEC infants with and those without cerebellar injury. Results Infants with cerebellar injury (21/65, 32.3%) had significantly more hemorrhagic and the reparative lesions on the intestinal histopathology, had patent ductus arteriosus (PDA) more often, received red cell transfusion frequently, had blood culture positive sepsis and grew gram positive organisms more often and had cholestasis frequently following NEC than those without cerebellar injury...

AIM: To analyze neurodevelopmental outcome of very and extremely preterm infants in Vorarlberg, Austria, accessed with neurodevelopmental testing, at the corrected age of 24 months. Also, to compare these results with (inter)national data and to analyze the impact of perinatal parameters. METHODS: Population-based, retrospective multi-centre study with data on very and extremely preterm infants born in Vorarlberg from 2007 - 2019, assessed with Bayley Scales of Infant Development (BSID-II/Bayley-III)...

We evaluated changes in patent ductus arteriosus (PDA) diagnosis and treatment from 2012 through 2021 in a network of U.S. academic hospitals. PDA treatment decreased among infants born at 26-28 weeks but not among infants born at 22-25 weeks. Rates of indomethacin use and PDA ligation decreased while acetaminophen use and transcatheter PDA closure increased.

Persistent patent ductus arteriosus is a very common condition in preterm infants. Although there is no management agreed by consensus, despite numerous randomized controlled trials, hemodynamically significant patent ductus arteriosus increases morbidity and mortality in these vulnerable patients. Medical treatment is usually offered as first-line therapy, although it carries a limited success rate and potential severe adverse events. In recent years, transcatheter patent ductus arteriosus closure has fast developed and become widely accepted as a safe and efficient alternative to surgical ductal ligation in extremely low birth weight infants >700 g, using most often the dedicated Amplatzer Piccolo Occluder device...

BACKROUND: Lung ultrasound (LUS) is a rapid and simple method to evaluate preterm babies with respiratory distress. Lately, LUS has also been reported as an accurate predictor for bronchopulmonary dysplasia (BPD). OBJECTIVES: The aim of the study was to investigate the relationship between the LUS scores within the first 3 days of life and respiratory outcomes including the need and the duration of invasive mechanical ventilation, and development of BPD. METHODS: It was a retrospective observational study...

OBJECTIVE: In extremely preterm infants, different target ranges for pulse oximeter saturation (SpO2 ) may affect mortality and morbidity. Thus, the impact of technical changes potentially affecting measurements should be assessed. We studied SpO2 readings from different sensors for systematic deviations. DESIGN: Single-centre, randomised, triple crossover study. SETTING: Tertiary neonatal intensive care unit. PATIENTS: 24 infants, born at <32 weeks' gestation, with current weight <1500 g and without right-to-left shunt via a patent ductus arteriosus...

BACKGROUND: The optimal treatment strategy for patent ductus arteriosus (PDA) in extremely preterm infants is currently highly controversial. This study aimed to evaluate the association between PDA treatment and short-term outcomes among extremely preterm infants. METHODS: This cohort study included all extremely preterm infants (≤27 and 6/7 weeks) who were admitted to hospitals participating in the Chinese Neonatal Network from January 2019 to December 2021, and were diagnosed to have PDA by echocardiogram...

BACKGROUND: Systemic lupus erythematosus (SLE), a common autoimmune disease predominantly affecting women, has been linked to various complications during pregnancy. The transfer of anti-Ro/SSA antibodies from SLE-affected mothers to their offspring can lead to neonatal lupus and cardiac issues. This study investigated the association between maternal SLE and the risk of pediatric cardiovascular disorders. METHODS: The study utilized South Korea's National Health Insurance Service (NHIS) database, covering 3,505,737 children born between 2007 and 2017 and tracked until 2020...

BACKGROUND: Gastrointestinal perforation in extremely low birth weight infants, characterized by its rapid onset, multiple complications, and critical condition, poses a significant risk of infant mortality. The aim of this study was to investigate the clinical characteristics of pneumoperitoneum in extremely low birth weight infants (ELBWI) and explore the risk factors associated with gastrointestinal perforation in very low birth weight preterm infants. Additionally, we shared our surgical experiences in managing gastrointestinal perforation among extremely low birth weight infants...

BACKGROUND: Dexamethasone is widely used as a systemic corticosteroid to treat and prevent bronchopulmonary dysplasia (BPD) in preterm infants. We evaluated the current epidemiology of dexamethasone use to prevent BPD and analyse the factors associated with the response to dexamethasone in very low birthweight infants using a nationwide database. METHODS: We included very low birthweight infants born between January 2013 and December 2020 with a gestational age of 23-31 weeks using data from the Korean Neonatal Network registry...

OBJECTIVE: To evaluate the temporal trend of bronchopulmonary dysplasia (BPD) in preterm infants who survived to at least 36 weeks' post-menstrual age (PMA) and BPD or death at 36 weeks' PMA, and to analyse variables associated with both outcomes. DESIGN: Retrospective cohort with data retrieved from an ongoing national registry. SETTING: 19 Brazilian university public hospitals. PATIENTS: Infants born between 2010 and 2019 with 23-31 weeks and birth weight 400-1499 g...

BACKGROUND: Retinopathy of prematurity (ROP) is a vasculoproliferative disorder of immature retina, seen in preterm babies. Multiple risk factors attribute to this condition. Our aim was to correlate the role of any early neonatal surgeries with low gestational age (GA) and birth weight (BW) on preterm babies as a risk factor on the progression of ROP. METHODS: A prospective, cohort study conducted in a hospital in South India over 3 years, including 600 babies with GA <35 weeks and BW <2500 g...

BACKGROUND: The benefit of surfactant replacement therapy for respiratory distress syndrome (RDS) has been demonstrated. However, some surfactants are expensive and usually inaccessible. Consequently, the Iranian Survanta was produced, but its effect on complications and mortality of RDS is unknown. This study aimed to compare the therapeutic outcomes of Iranian surfactant (beraksurf) and BLES (bovine lipid extract surfactant) on RDS treatment among preterm neonates. METHODS: This triple blinded randomized controlled trial study was performed on 128 eligible neonates diagnosed with RDS in Afzalipour hospital in Kerman, Iran...

BACKGROUND: Many preterm infants require respiratory support to maintain an optimal level of oxygenation, as oxygen levels both below and above the optimal range are associated with adverse outcomes. Optimal titration of oxygen therapy for these infants presents a major challenge, especially in neonatal intensive care units (NICUs) with suboptimal staffing. Devices that offer automated oxygen delivery during respiratory support of neonates have been developed since the 1970s, and individual trials have evaluated their effectiveness...

OBJECTIVE: Limited data exist comparing indomethacin and ibuprofen for the treatment of patent ductus arteriosus (PDA). The objective was to compare the safety and efficacy of indomethacin and ibuprofen for treatment of PDA closure. METHODS: This single-center, pre-test/post-test quasi-experiment included preterm infants admitted to the neonatal intensive care unit who received indomethacin (July 1, 2013-September 30, 2015) or ibuprofen (December 1, 2015-July 31, 2019) for PDA...

IMPORTANCE: Bronchopulmonary dysplasia (BPD) is often associated with pulmonary vascular disease and secondary pulmonary hypertension (PH). The pathogenesis of BPD-associated PH (BPD-PH) is complex and involves prenatal and postnatal factors that disrupt pulmonary vascular development, and patent ductus arteriosus (PDA) is a factor potentially associated with risk of BPD-PH that has been identified in very recent studies. OBJECTIVE: To explore the association of PDA with BPD-PH using a bayesian model-averaged (BMA) meta-analysis of studies...
