Antenatal steroids have improved the survival of preterm infants; however, the mechanism of action is not fully understood. We aimed to establish an association between antenatal steroids and antioxidant activity and postnatal oxidative stress. In a prospective cohort study, extremely preterm neonates receiving antenatal steroids (CORT) or not (NOCORT) were enrolled. An association between antenatal steroids and activities of antioxidant enzymes and glutathione cycle enzymes in cord blood was found. In addition, reduced oxidative stress (GSH/GSSG ratio, CORT vs. NOCORT, 35.68 +/- 12.20 vs. 28.38 +/- 9.92; p < 0.01) and, decreased oxidation of proteins (ortho-tyrosine/phenylalanine ratio, CORT vs. NOCORT, 8.66 +/- 2.45 vs. 12.55 +/- 4.41; p < 0.01) and DNA (8oxodG/2dG ratio, CORT vs. NOCORT, 6.73 +/- 2.18 vs. 9.53 +/- 3.83; p < 0.01) also was found. Antenatal steroids were associated with reduced oxygen supplementation, mechanical ventilation, and conditions such as bronchopulmonary dysplasia, intra-periventricular hemorrhage, or retinopathy of prematurity. The maximal effectiveness was when steroids were administered 2-4 days before delivery. Female preterm infants had less oxidative stress and increased antioxidant activity and better clinical outcomes than did male infants, independent of receiving or not antenatal steroids. Antenatal steroids are accompanied by a reduction in postnatal oxidative-stress-derived conditions and increased antioxidant enzyme activity. Both these effects seem to be influenced by specific timing and female gender. Antioxid. Redox Signal. 11, 2945-2955.

Summary: Oropharyngeal therapy with mother's own milk (OPT-MOM) did not reduce late-onset sepsis (L-OS), necrotizing enterocolitis (NEC) or death in preterm infants. However, there was a trend towards reduced length of stay and improved nutritional outcomes in the group receiving OPT-MOM.

Summary: In this study, researchers analyzed plasma samples from newborns using nuclear magnetic resonance (NMR) spectroscopy and found that lactate and other substances can discern the degree of brain injury. This is the first longitudinal study on infants with hypoxic-ischemic encephalopathy, and the measurement of lactate confirms its reliability as a biomarker for predicting the severity of brain injury.

Summary: Intermittent hypoxemia (IH) events in preterm neonates are associated with oxidative stress and damage to lipids, proteins, and DNA. This study explores the relationship between IH parameters and oxidative stress biomarkers in urine samples. The findings suggest that these biomarkers may be useful in identifying high-risk neonates.

Summary: This study investigated the relationship between neurotransmitter plasma levels and hypoxemia parameters in preterm neonates. The results showed that plasma levels of serotonin and kynurenic acid may serve as biomarkers for hypoxemia in preterm neonates. This research helps identify newborns at risk of short- and long-term adverse outcomes.

Summary: Accurately assessing dietary intake in nutritional research is challenging but crucial. To overcome the subjectivity of self-reporting methods, the development of analytical methods for determining food intake and microbiota biomarkers is necessary. This study presents a UHPLC-MS/MS method for quantifying and semi quantifying food intake biomarkers (BFIs) and microbiota biomarkers in urine samples from lactating mothers. The analysis identified distinct clusters of samples based on biomarker concentrations and revealed correlations between certain BFIs and dietary recall data. These findings emphasize the feasibility, usefulness, and complementary nature of assessing BFIs, dietary recall, and microbiota biomarkers in nutrition cohort studies.

Summary: This study aims to compare the effect of mother's own milk (OMM) and pasteurized donor human milk (DHM) on % weight gain/month in preterm and term infants. It also evaluates the impact of diet, lifestyle habits, psychological stress, and pasteurization on milk composition and their influence on infant growth, health, and development. Biological samples and various characteristics are collected at different time points for analysis. The study also involves the use of sensor prototypes, measurement of maternal psychosocial status, examination of postpartum bonding and parental stress, and application of neurodevelopment scales.

Summary: CellBender, with its deep generative model, is able to simulate and denoise droplet-based single-cell data, improving the accuracy of multiple downstream analyses. It accurately distinguishes cell-containing droplets from cell-free droplets, learns the background noise profile, and provides noise-free quantification in an end-to-end manner.

Exacerbated response to oxidative stress in the Retinitis Pigmentosa CerklKD/KO mouse model triggers retinal degeneration pathways upon acute light stress

Summary: The retina is highly susceptible to genetic and environmental changes that result in oxidative stress and cell damage. CERKL is an important gene that protects against oxidative stress in the retina. This study using a mouse model found that Cerkl knockdown leads to abnormal stress response and cell death mechanisms in the retina, ultimately causing blindness.

Summary: The high recurrence rate of cystine lithiasis in cystinuria patients calls for new therapeutic options. Antioxidant defect has been observed in cystinuria, leading to testing of antioxidant molecules as new treatments. In this study, L-Ergothioneine was found to decrease stone formation rate by over 60% and delay onset of calculi in a mouse model.

A Narrative Review of the Rationale for Conducting Neonatal Emergency Studies with a Waived or Deferred Consent Approach

Anup Katheria, Georg M. Schmolzer, Annie Janvier, Vishal Kapadia, Ola D. Saugstad, Maximo Vento, Alla Kushnir, Mark Tracy, Wade Rich, Ju Lee Oei

Summary: Emergency research studies, especially those involving newborn infants, often face difficulties in obtaining informed consent due to the severity of the patients' conditions. The waiver or deferred consent process is needed to include sick patients who are unable to provide prospective consent. However, this process can lead to conflicting stakeholder views and pose challenges to research. This manuscript discusses the necessity of consent waiver or deferred consent processes for neonatal emergency research and provides a framework to balance the patients' best interests with ethical knowledge acquisition.

Summary: This study aimed to investigate the effect of kangaroo care on cerebral fractional tissue oxygen extraction (FtOE) in premature infants and compare the stability of cardiorespiratory parameters and the occurrence of hypoxic or bradycardic events between kangaroo care and incubator care. The results showed that during kangaroo care, cerebral metabolic demand was lower and cerebral oxygenation was higher compared to post-kangaroo care period, indicating the advantage of kangaroo care in promoting cerebral oxygenation and reducing metabolic demand in premature infants.

Summary: The sixth version of European Guidelines for the Management of RDS has been developed by a panel of experienced European neonatologists and an expert perinatal obstetrician based on available literature up to end of 2022. These updated guidelines aim to optimize outcomes for babies with RDS through various measures such as prediction of risk of preterm delivery, appropriate maternal transfer to a perinatal center, and evidence-based lung-protective management. The guidelines also address the importance of general care for infants with RDS, including cardiovascular support and judicious use of antibiotics. The guidelines have received endorsement from the European Society for Paediatric Research (ESPR) and the Union of European Neonatal and Perinatal Societies (UENPS). Rating: 7 out of 10.
