Background: An early form of preeclampsia is rare. Abnormal placentation, placental perfusion disorders, and inflammatory cytokine release will have an effect on the fetus and newborn. Material and methods: The study group consisted of preterm newborns whose mothers had a history of preeclampsia and a gestational age of between 30 weeks and 34 weeks + 6 days. The control group consists of neonates matched for gestational age with the case group, whose mothers had normal blood pressure. The incidence and severity of respiratory distress syndrome (RDS), intraventricular hemorrhage, hypoglycemia, pH gas changes, and hematological parameters were analyzed in the two groups. Results: The study group of preterm neonates had a lower birth weight than the control group (p < 0.001). Most of the deliveries in the group of newborns exposed to preeclampsia were performed by cesarean section. Severe forms of RDS were two times more frequent in the group of newborns exposed to preeclampsia compared to those in the control group. Even though we expected to see a lower incidence, owing to the high number of deliveries by cesarean section, we still observed a higher rate of intraventricular hemorrhage in the preeclampsia group (16 cases in the study group vs. 7 in the control, p = 0.085). Neutropenia and thrombocytopenia were more frequent in preterm newborns exposed to preeclampsia. Conclusions: The study shows that early preeclampsia increases the risk of complications in preterm neonates. RDS was more frequent in the exposed group than in the control group. The severity of preeclampsia correlates with hematological changes.

Aim: To asses the cardiac morphology and functional changes specific for newborns from intrauterine growth restriction (IUGR) pregnancies.Material and method: A cohort of IUGR infants were evaluated by serial echocardiographies at delivery and at the first and six months follow-ups. IUGR newborn delivery status was compared to that of newborns in the control group according to gestational age (AGA).Results: Left heart measurements were significantly lower in IUGR newborns compared to AGA babies. Left ventricular size increased at follow-up inthe IUGR group (p 0.47) was identified in 40% of the neonates in the IUGR group (16/40), respectively 4.76% in the control group. IUGR neonates had a significantly increased proportion of systolic malfunction (p=0.004).Conclusion: IUGR patients had reduced left ventricle dimensions compared to AGA babies. The MPI stands out as a marker of leftheart function in newborns. Systolic dysfunction was a hallmark of the cardiac adaptation in IUGR neonates.

Background and objectives: Premature newborns have a number of oxidative stress-inducing disorders. Antioxidant defense is deficient in premature newborns. Hydrogen donors can be used to evaluate the non-enzymatic antioxidant defense. By measuring hydrogen donors, a group of antioxidants can be assessed: tocopherol, ascorbic acid, and glutathione. These represent the most relevant group of non-enzymatic antioxidants. The main aim of this study was to evaluate the non-enzymatic antioxidant defense capacity of premature newborns by measuring hydrogen donors. Materials and Methods: We evaluated the non-enzymatic antioxidant capacity by hydrogen donor measurement in 24 premature newborns with various oxidative stress-inducing disorders and in 14 premature newborns without oxidative stress-inducing conditions. Statistical analysis was performed using the Statistica program (v. 8, StatSoft, Round Rock, TX, USA). Differences between groups were tested with Wilcoxon matched test for quantitative paired data or Mann–Whitney test for quantitative independent data. The Z test for proportions was used to compare qualitative data among subgroups. Results: Hydrogen donors in the study group had a significantly lower value on the first day of life compared to the value of the control group. Also, the hydrogen donor value in the study group was significantly lower on the first day compared to the third day of life (p < 0.05). Neonates with mild respiratory distress (14 cases) had increased hydrogen donor values on their third day of life compared to the first day of life. Conclusions: The antioxidant capacity is influenced by oxidative stress-inducing disorders. Respiratory distress influenced the hydrogen donor value and antioxidant defense. Antioxidant defense gradually improves after birth according to gestational age.

Necrotizing enterocolitis (NEC) is probably the most painful intestinal disease affecting infants born preterm. NEC is known to cause highly severe and prolonged pain that has been associated with adverse short- and long-term effects. However, research on pain management in infants with NEC is scarce. This is likely due to its low incidence and very acute occurrence. As a result, the optimal pain management for these vulnerable infants remains unknown, and analgesic therapy practices are highly variable. Therefore, we aimed to establish expert-based consensus recommendations on pain management for NEC. Experts of the European Society for Paediatric Research (ESPR) Special Interest Groups on Neonatal pain and NEC were invited to participate in two consensus meetings. Prior to the first hybrid consensus meeting, an online survey provided input for potential recommendations. During the consensus meetings, experts shared clinical expertise and voted on recommendations. An expert consensus statement, comprising nine recommendations on optimal pain assessment and pain treatment in infants with NEC, was developed. Expert recommendations included regular pain assessments with a neonatal pain scale with additional assessments on indication and pre-emptive administration of analgesic therapy (e.g., paracetamol and an opioid) in infants with NEC stage ≥ II. Conclusion: This expert consensus statement provides clinical recommendations essential for any healthcare professional caring for premature infants with NEC. The recommended guidance this statement provides on pain management strategies is key to preventing and reducing pain in this vulnerable population. What is Known: •  Necrotizing enterocolitis (NEC) is a very painful disease, making effective pain management essential.• Current pain management practices for infants with NEC are highly variable. What is New: •  This expert consensus statement provides recommendations on optimal pain assessment and pain treatment in infants with NEC.• These clinical recommendations may help better prevent pain in these vulnerable infants.

Background: Epidermolysis bullosa is a rare form of genodermatosis produced by different gene mutations. The junctional form of the disease (JEB-PA) can associate pyloric atresia, renal abnormalities, and aplasia cutis congenita.Case Description: A case of a male preterm newborn with suspicion of digestive tube malformation at fetal ultrasound and who was born by cesarian section. At birth, he presented extensive cutaneous aplasia on the lower limbs and bilaterally under ears; outer ear agenesis; nasal septum hypoplasia; micrognathia; multiple blisters on the face, trunk, and limbs; lower limb deformities and absence of toe nails. Pathological examination following a surgical procedure with unfavorable outcome showed pyloric atresia, junctional form of epidermolysis bullosa and aplasia cutis congenita. Homozygous variants in two genes were identified: c.3111+1G>A in ITGB4 (class 5) and c.1498G>T in KRT10 (class 3).Conclusion: The particularity of our case is the novel finding of a coincidental occurrence in the context of consaguinity of two mutations in the ITGB4 and KRT10 genes, and clinical characteristics of epidermolysis bullosa.

More than half of preterm births are triggered by inflammatory processes at the foeto-maternal interface. These inflammatory processes can persist after birth due to the unique vulnerabilities of preterm infants, often resulting in sustained inflammation with a role in complications such as bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH), and periventricular leukomalacia (PVL). The aim of this study was to evaluate the predictive value of maternal inflammatory status, assessed through biomarkers of inflammation (CRP, chorioamnionitis, preeclampsia), and neonatal inflammatory markers (CRP 1, CRP 2, PCT, IL3, MMP9) on the incidence of NEC in preterm neonates. We conducted a prospective longitudinal study in the 1st Neonatology Department, Cluj-Napoca, Romania. A total of 82 preterm newborns (gestational age < 34 weeks + 6 days) were enrolled in the study. Interleukin-3 (IL3) and matrix metalloproteinase-9 (MMP9) levels were measured using the ELISA technique. Additionally, C-reactive protein (CRP) and procalcitonin (PCT) were measured in the first days of life. The correlation between these inflammatory markers and the incidence of NEC was analyzed. Furthermore, we examined the role of maternal inflammation and chorioamnionitis in relation to NEC incidence. Out of the 82 neonates enrolled, 20 developed NEC. Neonates who developed NEC had higher IL3 levels at birth. A significant positive correlation was found between maternal CRP levels and neonatal IL3 levels (r = 0.541, p < 0.001). In the NEC group, maternal CRP levels were also elevated compared to those in neonates who did not develop NEC. Conclusion: Neonatal inflammation is associated with an increased incidence of NEC. Prenatal inflammatory conditions appear to trigger a persistent inflammatory process in preterm neonates, raising the risk of NEC. What is Known: • NEC is a multifactorial disease of preterm newborn with multiple maternal and neonatal risk factors. What is New: • Evaluate the probability of NEC at preterm neonates of mothers with ongoing inflammatory conditions during pregnancy.
