Summary: Perinatal asphyxia is a major cause of neurodegeneration in full-term newborns, leading to hypoxic-ischemic encephalopathy, which is the leading cause of mortality in term newborns. Despite the standard use of hypothermia, there is still a need for effective treatment strategies. Recent research suggests that melatonin, a natural compound with neuroprotective properties, may be used in the treatment of hypoxic-ischemic encephalopathy. However, clinical trials on a sufficient number of newborns have not yet been conducted, and further research is needed to explore the advantages and limitations of melatonin in perinatal asphyxia treatment.

Summary: Hypoxic-ischemic encephalopathy (HIE) leads to mortality and long-term neurologic morbidities in newborns, involving energy failure, excitotoxicity, and oxidative stress. Quercetin has been shown to have neuroprotective effects in perinatal asphyxia models, reducing mortality and affecting protein expression. The glycolytic pathway is strongly regulated by quercetin in both rat and piglet models, indicating potential neuroprotective mechanisms.

Summary: Perinatal asphyxia is a pathological condition caused by inadequate oxygen supply to internal organs, leading to hypoxic-ischemic encephalopathy as its clinical manifestation. The search for biomarkers and treatment strategies to predict the severity of lesions is ongoing, with hypothermia proving to be an effective neuroprotective strategy.

Summary: Spinal cord injury (SCI) is a sudden disruption to the spinal neural tissue, causing loss of motor control and sensory function. Melatonin, a hormone with antioxidant properties, has been shown to have neuroprotective effects in SCI, reducing inflammation, oxidative stress, and cell death. This review highlights the potential applications of melatonin in SCI rehabilitation, including its synergistic effects with drugs, rehabilitation training, and stem cell therapy.

Summary: Age is an important predictor of unfavorable prognosis after brain trauma, and the effective treatment for geriatric TBI is currently limited. Through experiments on middle-aged animals, it has been found that thyroid hormones play a role in regulating TBI susceptibility, and thyroid dysfunction may be a crucial pathology in the increased severity of TBI in older individuals. By surgically removing the thyroid glands, it has been shown that the endogenous thyroid hormone-dependent compensatory regulation of antioxidant events can modulate individual TBI susceptibility, and acute melatonin treatment shows potential for improving TBI-susceptible phenotypes in aged individuals with thyroid dysfunction.

Summary: The ethyl acetate and n-butanol fractions of Zanthoxylum bungeanum were found to significantly relieve d-galactose-induced memory deficit in mice. Ethyl acetate was able to protect neurons, alleviate oxidative damage, and inhibit microglia activation in aging mice. Additionally, the EA fraction showed inhibitory effects on the NLRP3 inflammasome pathway and GSDMD-mediated pyroptosis in both aging mice and LPS/ATP-induced BV-2 microglial cells.

Summary: Background: Creatine supplementation during pregnancy is a potential treatment for perinatal hypoxic brain injury. This study investigated the effects of acute hypoxia and creatine supplementation on neuropathology in fetal sheep. Results: Acute hypoxia caused mild injury to multiple brain regions, but creatine supplementation did not ameliorate these changes. However, creatine supplementation did affect gene expression that may impact in utero cerebral development.

Summary: This review focuses on the molecular mechanisms of hypoxic-ischemic encephalopathy, specifically highlighting the importance of apoptosis-inducing factor. Understanding the roles of this factor is crucial for developing more effective treatments for perinatal brain injury. Additionally, the interaction of apoptosis-inducing factor with other proteins may provide promising therapeutic targets for improving outcomes after perinatal brain injury.

Summary: Metabolomics plays a crucial role in assessing oxidative stress in perinatal asphyxia, with potential diagnostic and prognostic implications. While blood, plasma, and urine are commonly used for metabolomics analyses, the potential of saliva remains underexplored. Accumulating evidence supports the development of bedside methods to measure oxidative stress metabolites, with saliva as a candidate biofluid for point-of-care diagnostics.

Summary: This study explores selected long non-coding RNAs (lncRNAs) and their protein-coding target genes using a piglet model of perinatal asphyxia. The results show significant changes in lncRNA expression, mainly in the cortex and hippocampus, induced by a brief exposure to 100% oxygen for 3 minutes. The findings suggest that lncRNAs are part of the molecular response to hypoxia-induced damage during perinatal asphyxia, and a better understanding of their regulatory properties may provide novel targets and intervention strategies in the future.

Summary: Maternal magnesium sulphate (MgSO4) treatment before preterm birth for neuroprotection is controversial due to limited evidence of long-term neuroprotection. In this study, preterm fetal sheep received MgSO4 infusion before hypoxia-ischaemia induced by umbilical cord occlusion. Although MgSO4 showed moderate improvements in white and grey matter gliosis and myelin density, it did not improve EEG maturation, neuronal or oligodendrocyte survival.

Summary: This study examined fetal MR imaging findings in patients with tuberous sclerosis complex (TSC). The results showed that normal fetal MR imaging findings were more common at a lower gestational age, and abnormal findings were more common at a higher gestational age. Various phenotypes were observed, including subependymal nodules, cortical/subcortical lesions, and foramen of Monro nodules. Fetal hemimegalencephaly and megalencephaly should prompt fetal echocardiography. Cardiac rhabdomyoma was not always present at the time of fetal MR imaging.

Summary: This study aims to investigate the long-term impacts of SARS-CoV-2 exposure on children exposed in utero. Women infected with SARS-CoV-2 during pregnancy will be recruited and compared with non-exposed women. By conducting long-term observations and comparisons, we hope to reveal the potential effects of in utero exposure to SARS-CoV-2 on neurodevelopment.

Summary: Umbilical cord blood-derived cell therapy significantly improves multiple outcomes in preclinical models of perinatal brain injury, including decreased infarct size, inhibition of apoptosis, alleviation of astrogliosis, reduction of microglial activation and neuroinflammation, as well as increased neuron and oligodendrocyte numbers, and improved motor function. However, the findings are limited by low certainty of evidence.

Summary: Beginning in early 2022, severe pediatric hepatitis clusters were reported in Europe and the United States. No specific cause has been identified, although human adenovirus 41 has been proposed in some cases. In Victoria, Australia, there were positive associations between pediatric hepatitis clusters and respiratory viruses, but no association with respiratory adenoviruses or SARS-CoV-2. The current hepatitis outbreak is novel and unlikely to be related to respiratory adenoviruses or SARS-CoV-2.

Summary: The diagnosis of cerebral palsy is currently based on clinical observations only and does not consider aetiology or pathology. This study reviews the current state of genomic testing in cerebral palsy and emphasizes the benefits of a 'genotype-first' approach. It is found that around one-third of cases have an underlying genetic cause, which overlaps with other neurodevelopmental disorders. The study highlights the importance of considering aetiology during clinical diagnosis and the opportunity for comprehensive genomic testing in early diagnosis of cerebral palsy.

Summary: This study aimed to investigate the presence of neurodevelopmental disabilities in child survivors of monochorionic pregnancies managed by placental laser photocoagulation in Victoria, Australia. The study found that approximately 31% of the survivors had neurodevelopmental impairment, with speech/language disorders, attention deficit (hyperactivity) disorders, and fine motor impairment being the most common. Neonatal length of stay was identified as the highest risk factor for impairment.
