Special Issue Information

Dear Colleagues,

Hypoxic–ischemic brain injury remains a leading cause of neonatal mortality and long-term neurodevelopmental disabilities, primarily affecting the term-born population, although preterm infants may also be at risk. Despite remarkable advances in perinatal care, the diagnosis and therapy of neonatal brain injury remain a challenge, and therapies are largely supportive. The only established clinical intervention for hypoxic–ischemic brain injury is therapeutic hypothermia demonstrating reductions in risk of death or impairment. However, half of treated infants still suffer from major neurological problems such as cerebral palsy or epilepsy. Furthermore, in preterm infants, therapeutic hypothermia cannot be applied due to its side effects and insufficiency.

This Special Issue critically examines challenges in optimizing treatment and timing, improving access to care in low-resource settings, and addressing long-term outcomes. Additionally, the Issue highlights future directions, including precision medicine approaches, artificial intelligence in early diagnosis, and innovative rehabilitation methods. By integrating multidisciplinary perspectives, this Special Issue aims to bridge the gaps between research and clinical practice, serving as a comprehensive resource for clinicians and researchers and fostering improved outcomes for affected newborns worldwide.

Background/Objectives: Hypoxic–ischemic encephalopathy is the leading cause of infant mortality and disability. Hypothermic therapy is effective in hypoxic–ischemic encephalopathy, albeit in a limited number of cases. Hypothermia requires advanced technologies and significant financial resources, which are difficult to sustain in low-income countries, with devastating consequences. Valid alternatives to hypothermia therapy are therefore needed. Methods: In vitro organotypic cultures of mouse cerebral cortex slices were used to demonstrate the direct protective effect of N-acetylcysteine (NAC) against brain tissue damage induced by oxygen–glucose deprivation (OGD), and to identify the concentrations and time window that maximize the drug’s effectiveness. NAC’s effectiveness was measured by the incorporation of propidium iodide (PI), a marker of cell membrane integrity. Results: Adding 0.1 and 1 mM NAC to the incubation medium before OGD strongly reduced OGD-induced PI incorporation, by 80% (p < 0.0002) and 89% (p < 0.0001), respectively. Administration of 1 mM NAC 1 h after OGD maintained a high degree of protection against OGD-induced damage (80% reduction in PI incorporation; p < 0.0001), while at 0.1 mM, the efficacy of NAC dropped to 44% (p < 0.005). Administration of NAC 4 h after OGD reduced PI incorporation to 52% (p < 0.005) at 1 mM, while at 0.1 mM, the effect was not significant (17%; p > 0.05). Exposure of slices to 0.1 and 1 mM NAC reduced PI incorporation in female cerebral cortex slices (p < 0.006), while only the higher concentration was effective in male slices (p < 0.05). Exposure to 0.1 mM NAC increased tissue levels of total glutathione (p = 0.0185), while no significant effect was observed with 1 mM NAC. Conclusions: This work highlights the direct effect of NAC in protecting cerebral cortex cells from OGD-induced damage and identifies the concentrations and time window that maximize the drug’s effect. The results underscore the need for further studies to verify the in vivo efficacy of NAC at concentrations found to be active in vitro, and for clinical trials to evaluate whether NAC can reduce hypoxia-induced brain damage in newborns.

Background/Objectives: Neonates with hypoxic–ischemic encephalopathy (HIE) are born in delivery facilities with different levels of neonatal care. The objective of this study was to investigate differences in the incidence of HIE and postnatal management between different levels of neonatal care in delivery facilities. Methods: This is a retrospective, multi-center cohort study of neonates with moderate-to-severe HIE receiving therapeutic hypothermia (TH) in the Canton of Zurich, Switzerland, registered in the Swiss National Asphyxia and Cooling Register between 2015 and 2023. Incidences of HIE receiving TH were calculated for all delivery facilities according to the national levels of neonatal care on site (Level I—basic; Level IIB—intermediate (no Level IIA facility in the Canton of Zurich); Level III—intensive neonatal care). Perinatal characteristics and variables on transport and outcomes were compared between neonates born in Level I and Level IIB facilities (the majority of the HIE population) and reported for neonates born in all other facilities (for completeness). Results: A total of 173 neonates (79 (45.7%) born in Level I; 80 (46.2%) in Level IIB; 9 (5.2%) in Level III; 5 (2.9%) in birthing centers) were admitted to a neonatal cooling center to receive TH. The average number of annual cases of HIE receiving TH per facility was 0.67 (0.11–1.50) in Level I and 2.22 (0.22–3.11) in Level IIB facilities (p = 0.088), respectively. There was no difference in Apgar score, worst pH (within 60 min after birth) and the severity of encephalopathy between neonates born in Level I and Level IIB facilities. Neonatal transport team requests were initiated earlier in Level I facilities (median 12 vs. 34 min of life, p < 0.001). There was no difference in age at initiation of TH (median 3 vs. 3 h, p = 0.431) and the time when target temperature was reached (median 4 vs. 4 h, p = 0.431) between neonates born in Level I and Level IIB facilities. Conclusions: The level of neonatal care available in delivery facilities influenced the management of neonates with HIE receiving TH. Full article
