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.

Fetal inflammatory response syndrome is associated with increased neonatal morbidity and mortality. The aim of the present study was to evaluate the dynamics of the plasmatic value of pro‑inflammatory cytokines: tumor necrosis factor‑α (TNF‑α), interleukin‑6 (IL‑6) and neutrophil activating peptide 78 (ENA‑78) and the anti‑inflammatory cytokine IL‑10 in the first and third day of life and the correlation with neonatal morbidities and mortality. The current research was designed as a prospective case control study included 80 neonates hospitalized at the 3rd level Neonatal Intensive Care Unit (NICU), 1st Gynecology Clinic, County Emergency Hospital, Cluj‑Napoca, Romania. For each patient, the following parameters were noted: pH at first hour of life, oxygen saturation, fraction of inspired oxygen (FiO₂) and duration of premature rupture of the membranes (PROM). Measurements of cytokines were determined from venous blood in the first and third day of life. The values of all cytokines were higher in the newborns from mothers with PROM. The value of IL‑6 in the study group was higher compared to the controls during the first day of life and met the highest value in necrotizing enterocolitis (NEC). ENA‑78 was higher in the study group (P=0.037) and decreased during the first 3 days of life. The highest value of ENA‑78 was found in the neonates with cerebral hemorrhage. IL‑10 also had values with a significant difference in the first day of life between both groups (P=0.02). IL‑10 had the highest value in sepsis cases. In conclusion, among the inflammatory parameters that were evaluated, the dynamics of ENA‑78 and IL‑10 were found to influence the neonatal prognosis of newborns with PROM. The decrease in ENA‑78 and IL‑10 during the third day of life could suggest the evolution towards the ending of the inflammatory process and an increase in the survival rate was noted.

(1) Background: Neonatal sepsis continues to be one of the leading causes of mortality and morbidity, particularly in underdeveloped countries. We aimed to compare laboratory parameters between clinical early-onset sepsis (clinEOS) and NNNon-clinEOS groups and to evaluate the association between TLR2-Arg753Gln, TLR4-Asp299Gly, IL6-174G/C, and IL10-1082G/A gene single-nucleotide polymorphisms and clinical EOS susceptibility in preterm newborns. (2) Materials and Methods: Genotyping of the TLR2, TLR4, IL6, and IL10 polymorphisms was performed in 36 preterm neonates with polymerase chain reaction (PCR) and restriction fragment length polymorphism analysis (RFLP). Logistic regression analysis was used to test the associations between the studied gene polymorphisms and EOS susceptibility. (3) Results: Statistically significant differences in gestational age and birth weight were observed between the two groups, with preterm neonates with clinical EOS having a lower mean gestational age (mean (SD): 29.4 (2.8) weeks vs. 32.6 (1.1); p = 0.00002) and a lower mean birth weight (1342.1 (446.5) gr. Vs. 1984 (376.9)) than preterm neonates without clinical EOS. C-reactive protein (CRP) values measured on the first day significantly increased in the clinEOS group compared with the non-clinEOS group (median, 95% CI: 0.80 [0.40, 1.15] vs. 0.30 [0.02, 0.50]). The mean number of neutrophils significantly decreased in the preterm neonates with clinical EOS (mean difference: 17.3%; 95% CI: [4.0%, 30.5%]; p = 0.0126) and non-clinEOS group (mean difference: 20.8%; 95% CI: [1.8%, 39.9%]; p = 0.0354) between the first and seventh hospitalization days. In the dominant model, the A/G + A/A variant genotype of the IL10-1082G/A polymorphism significantly increased the odds of clinical EOS compared with the GG genotype (OR = 5.25; p = 0.0322), but the gestational-age-group adjusted model yielded p = 0.0752. (4) Conclusions: The results of the current study suggest that IL10-1082G/A gene polymorphism is a significant risk factor for clinical early-onset sepsis development in preterm neonates, but there was no evidence of a gestational age-group independent direct effect of IL10-1082G/A gene polymorphism on clinical EOS susceptibility. The results should be considered as exploratory.
