Growth hormone promotes myelin repair after chronic hypoxia via triggering pericyte-dependent angiogenesis.

White matter injury (WMI) causes oligodendrocyte precursor cell (OPC) differentiation arrest and functional deficits, with no effective therapies to date. Here, we report increased expression of growth hormone (GH) in the hypoxic neonatal mouse brain, a model of WMI. GH treatment during or post hypoxic exposure rescues hypoxia-induced hypomyelination and promotes functional recovery in adolescent mice. Single-cell sequencing reveals that Ghr mRNA expression is highly enriched in vascular cells. Cell-lineage labeling and tracing identify the GHR-expressing vascular cells as a subpopulation of pericytes. These cells display tip-cell-like morphology with kinetic polarized filopodia revealed by two-photon live imaging and seemingly direct blood vessel branching and bridging. Gain-of-function and loss-of-function experiments indicate that GHR signaling in pericytes is sufficient to modulate angiogenesis in neonatal brains, which enhances OPC differentiation and myelination indirectly. These findings demonstrate that targeting GHR and/or downstream effectors may represent a promising therapeutic strategy for WMI.

Congenital Myopathy Due to RyR1 Gene Mutation in a Newborn Masquerading as a Consequence of Hypoxic-ischemic Encephalopathy

Background: Congenital myopathies may be a cause of prolonged and persistent hypotonia and weakness in a newborn, which may be overlooked as a neurological consequence of hypoxic-ischemic encephalopathy. We report such a neonate which turned out to be a case of central core myopathy. Clinical Description: A female neonate born at 38 weeks of gestation suffered birth asphyxia and was referred at 25 days of life due to a persistent need for respiratory support. A review of history revealed that the mother had decreased fetal movements during the third trimester and polyhydramnios. On examination, the baby had a frog-like posture with a paucity of proximal movements with preserved distal movements. Considering the possibility of a congenital myopathy, investigations were carried out. The whole-exome sequencing revealed heterozygous nonsense variation in exon 20 of the RyR1 gene, thus diagnosing the infant as a case of congenital core myopathy. Management and Outcome: The baby was managed with supportive care including ventilatory and nutritional support. Baby remained ventilator dependent, but ultimately succumbed to complications by 2 months of age. Conclusions: A high index of suspicion is required in a newborn with birth asphyxia having unusually persistent hypotonia, thorough clinical examination and appropriate genetic testing can help in identifying an underlying congenital myopathy.

Vagus Nerve Stimulation for Improvement of Vascular Cognitive Impairment.

Vagus nerve stimulation (VNS) is acknowledged as a highly effective therapy for various neurological conditions, including refractory epilepsy, depression, Alzheimer's disease (AD), migraine, and stroke. Presently, there is an increasing focus on understanding the impact of VNS on cognitive aspects. Numerous studies suggest that VNS suppresses the body's inflammatory response, leading to enhanced cognitive function in patients. Vascular cognitive impairment (VCI) is a severe cognitive dysfunction syndrome resulting from prolonged chronic cerebral hypoperfusion (CCH), where the primary pathogenesis is CCH-induced neuroinflammation. In this paper, we present a comprehensive overview of the research advancements in using VNS for treating VCI and discuss that VNS improves cognitive function in VCI patients by suppressing neuroinflammation, offering insights into a potential novel approach for addressing this condition.

Internal jugular vein‐femoral vein diversion during anterior mediastinal mass resection and superior vena cava replacement

SummarySurgery which involves anterior mediastinal mass resection with artificial replacement of the superior vena cava results in significant disruption to the circulatory system. In this case, a pathway was established to divert blood from the internal jugular to the femoral vein after clamping of the superior vena cava. Blood which would ordinarily return to the right atrium via the superior vena cava was now being returned via the inferior vena cava. The mean arterial pressure was maintained at least 50 mmHg higher than the central venous pressure during clamping of the superior vena cava to avoid cerebral hypoperfusion. The combined use of the above strategies aimed to provide satisfactory surgical conditions and cerebral protection.

High-frequency repetitive transcranial magnetic stimulation ameliorates memory impairment by inhibiting neuroinflammation in the chronic cerebral hypoperfusion mice.

High-frequency repetitive transcranial magnetic stimulation (HF-rTMS) has been found to ameliorate cognitive impairment. However, the effects of HF-rTMS remain unknown in chronic cerebral hypoperfusion (CCH). To investigate the effects of HF-rTMS on cognitive improvement and its potential mechanisms in CCH mice. Daily HF-rTMS therapy was delivered after bilateral carotid stenosis (BCAS) and continued for 14 days. The mice were randomly assigned to three groups: the sham group, the model group, and the HF-rTMS group. The Y maze and the new object recognition test were used to assess cognitive function. The expressions of MAP-2, synapsis, Myelin basic protein(MBP), and brain-derived growth factors (BDNF) were analyzed by immunofluorescence staining and western blot to evaluate neuronal plasticity and white matter myelin regeneration. Nissl staining and the expression of caspase-3, Bax, and Bcl-2 were used to observe neuronal apoptosis. In addition, the activation of microglia and astrocytes were evaluated by fluorescence staining. The inflammation levels of IL-1β, IL-6, and Tumor Necrosis Factor(TNF)-α were detected by qPCR in the hippocampus of mice in each group. Via behavioral tests, the BCAS mice showed reduced a rate of new object preference and decreased a rate of spontaneous alternations, while HF-rTMS significantly improved hippocampal learning and memory deficits. In addition, the mice in the model group showed decreased levels of MAP-2, synapsis, MBP, and BDNF, while HF-rTMS treatment reversed these effects. As expected, activated microglia and astrocytes increased in the model group, but HF-rTMS treatment suppressed these changes. HF-rTMS decreased BCAS-induced neuronal apoptosis and the expression of pro-apoptotic protein (Caspase-3 and Bax) and increased the expression of anti-apoptotic protein (Bcl-2). In addition, HF-rTMS inhibited the expression of inflammatory cytokines (IL-1β, IL-6, and TNF-α). HF-rTMS alleviates cognitive impairment in CCH mice by enhancing neuronal plasticity and inhibiting inflammation, thus serving as a potential method for vascular cognitive impairment.

Pericytes: Unsung heroes in myelin repair after neonatal brain hypoxia.

Preterm infants can face lasting neurodevelopmental challenges due to hypoxia-induced injury of the cerebral white matter. In this issue of Neuron, Ren etal.1 identify microvascular pericytes as unexpected targets for growth hormone signaling, which enhances angiogenesis and remyelination after hypoxic injury in the developing mouse brain.

Babinski reflex evaluation in term neonates with hypoxic ischemic encephalopathy: Across-sectional observational study

Background: Assessment of primitive reflexes is one of the earliest, easiest and most frequently used method among health care workers for newborns and young infants. Babinski reflex is one of the infantile reflexes. Our aim was to study Babinski reflex in a term neonates with hypoxic ischemic encephalopathy (HIE). The incidence of HIE in developed countries is estimated to be 1.5 per 1,000 live births. Estimates in developing countries range from 2.3-26.5 per 1,000 live births. Methods: This study is a cross-sectional observational study. 70 consecutive neonates fulfilling criteria of HIE according to Sarnat and Sarnat classification, admitted in our neonatal intensive care unit (NICU) were included. It was elicited from 12 hours after birth to 72 hours of birth. Babinski response was assessed using thumb nail drag method. Results: 83% babies are born to 18-35 years and 17% to elderly gravid. 55% are delivered through normal vaginal delivery and 45% to LSCS. 52% neonates belong to HIE stage I, 30% and 18% neonates belong to HIE stage II and III respectively. In HIE stage I, planter grasp was elicitable in 89%. It remains non-elicitable in 44% and 91% in HIE stages II and III respectively. Conclusions: Absence of Babinski reflex can be correlated with the increase in severity of HIE. It is important to include the assessment of Babinski reflex along with other primitive reflexes in the newborn generally and especially in HIE.

Analysis of the efficacy of hyperbaric oxygen therapy for disorders of consciousness: A retrospective cohort study.

To analyze the efficacy and associated factors affecting the prognosis in patients with disturbance of consciousness after hyperbaric oxygen (HBO) treatment. A retrospective study was carried out on patients with disorders of consciousness (DOC) receiving HBO treatment from January to January 2022 in the Second Department of Rehabilitation Medicine of the Second Hospital of Hebei Medical University, China. HBO therapy improved the Glasgow Coma Scale (GCS) and Chinese Nanjing Persistent Vegetative State Scale (CNPVSS), as well as the clinical efficacy in patients with DOC. The comparison of GCS and CNPVSS scores in patients with DOC before and after HBO treatment was all statistically significant, with 325 patients (67.1%) showing effective results and 159 patients (32.9%) having unchanged outcomes. Univariate analysis indicated that there were statistically significant differences in age, HBO intervention time, HBO treatment times, pre-treatment GCS score, and etiology and underlying diseases between the good and poor prognoses groups. Multivariate regression analysis showed that HBO intervention time ≤7 days, HBO treatment ＞ times, high GCS score before HBO treatment, and brain trauma were independent influencing factors in achieving a good prognosis for patients with DOC. Low pre-treatment GCS scores were an independent risk factor for a poor prognosis in patients with brain trauma while being male, late HBO intervention time, fewer HBO treatment times, and low pre-treatment GCS scores were independent risk factors for a poor prognosis in patients with DOC after a stroke. Being ≥50 years of age, late HBO intervention time, and low pre-treatment GCS scores were independent risk factors for a poor prognosis in patients with DOC after hypoxic-ischaemic encephalopathy. HBO therapy can improve the GCS, CNPVSS scores and clinical efficacy in patients with DOC, and the timing of HBO intervention ≤7 days, times of HBO treatment, high pre-treatment GCS score, and brain trauma were the independent influencing factors of good prognosis in patients with DOC.

FEATURES OF ANESTHESIA IN PATIENTS WITH SPECIAL NEEDS. PART 1

The non-medical use of cannabis can negatively impact the morpho-functional state of almost all organs and systems of the human body. During acute intoxication and established drug dependence, it can unevenly distort the effects of drugs for local and general anesthesia, leading to life-threatening complications. Part 1 of this review presents the results of acute and chronic cannabis use on homeostasis. Cerebral vasospasm and atherosclerosis are identified as major etiological factors for cannabis-related cerebrovascular diseases. Young to middle-aged individuals (30–50 years), male gender (male-to-female ratio 3.7:1), and chronic use (86%) are significant independent predictors of neurovascular toxicity, cerebral hypoperfusion, and stroke. Cannabis smoking causes damage to the respiratory mucosa similar to tobacco. Regular cannabis smokers can expect irritation of the upper respiratory tract, swelling, obstruction, chronic cough, bronchitis, lung emphysema, and bronchospasm. Some reports advocate the use of dexamethasone during surgery to alleviate these symptoms. The detrimental effects of chronic cannabis use on liver and kidney functions are somewhat overstated. Disturbances in immune system, thermoregulation, blood clotting, and carbohydrate metabolism in the absence of anesthetic precautions can significantly complicate the patient's condition in the perioperative period. Cannabinoids can interact with drugs from various groups. Awareness of the pathophysiological and biochemical consequences of cannabis use allows anesthesiologists to anticipate and effectively manage perioperative complications in this patient category

Research Progress of Regulating Endoplasmic Reticulum Stress by Traditional Chinese Medicine in the Treatment of Vascular Dementia

Vascular dementia (VaD) is a cognitive dysfunction syndrome directly related to cerebral hypoperfusion caused by cerebral vascular injury. The pathogenesis of this disease is complex, and the western medicine is not effective in the treatment of this disease. Traditional Chinese medicine believes that the disease is located in the brain, due to the stasis of the brain collaterals and resulting in the emptying of the marrow sea. Traditional Chinese medicine (TCM) has the advantages of individualization and integration in the treatment of this disease, and its mechanism has been studied from the perspectives of oxidative stress, central cholinergic system, neuroinflammation, neuronal apoptosis and synaptic plasticity. At present, it is a new research direction to treat vascular dementia by regulating endoplasmic reticulum stress with traditional Chinese medicine. Therefore, this paper systematically elaborated the mechanism of ER stress in vascular dementia, and the mechanism of TCM regulation of ER stress in the treatment of VaD, in order to provide new ideas and new methods for TCM clinical diagnosis and treatment of VaD and basic research.

Practice Variations for Therapeutic Hypothermia in Neonates with Hypoxic-ischemic Encephalopathy: An International Survey

To evaluate variations in management of therapeutic hypothermia (TH) for neonatal hypoxic-ischemic encephalopathy (HIE) among international clinical sites and to identify areas for harmonization. An electronic survey was sent to Children's Hospitals Neonatal Consortium site sponsors, Canadian Neonatal Network site investigators, members of the Newborn Brain Society, and American Academy of Pediatrics Neonatology chiefs. One hundred five sites responded, with most from high-income regions (n=95). Groupings were adapted from the United Nations regional groups: US (n=52 sites); Canada (n=20); Western Europe and other states excluding Canada and US Group (WEOG, n=18); and non-WEOG (central and eastern Europe, Asia, Africa, Latin America, and Caribbean, n=15). Regional variations were seen in the eligibility criteria for TH, such as the minimum gestational age, grading of HIE severity, use of electroencephalography, and the frequency of providing TH for mild HIE. Active TH during transport varied among regions and was less likely in smaller volume sites. Amplitude-integrated electroencephalogram and/or continuous electroencephalogram to determine eligibility for TH was used by most sites in WEOG and non-WEOG but infrequently by the US and Canada Groups. For sedation during TH, morphine was most frequently used as first choice but there was relatively high (33%) use of dexmedetomidine in the US Group. Timing of brain magnetic resonance imaging and neurodevelopmental follow-up were variable. Neurodevelopmental follow occurred earlier and more frequently, although for a shorter duration, in the non-WEOG. We found significant variations in practices for TH for HIE across regions internationally. Future guidelines should incorporate resource availability in a global perspective.

MSE-VGG: A Novel Deep Learning Approach Based on EEG for Rapid Ischemic Stroke Detection.

Ischemic stroke is a type of brain dysfunction caused by pathological changes in the blood vessels of the brain which leads to brain tissue ischemia and hypoxia and ultimately results in cell necrosis. Without timely and effective treatment in the early time window, ischemic stroke can lead to long-term disability and even death. Therefore, rapid detection is crucial in patients with ischemic stroke. In this study, we developed a deep learning model based on fusion features extracted from electroencephalography (EEG) signals for the fast detection of ischemic stroke. Specifically, we recruited 20 ischemic stroke patients who underwent EEG examination during the acute phase of stroke and collected EEG signals from 19 adults with no history of stroke as a control group. Afterwards, we constructed correlation-weighted Phase Lag Index (cwPLI), a novel feature, to explore the synchronization information and functional connectivity between EEG channels. Moreover, the spatio-temporal information from functional connectivity and the nonlinear information from complexity were fused by combining the cwPLI matrix and Sample Entropy (SaEn) together to further improve the discriminative ability of the model. Finally, the novel MSE-VGG network was employed as a classifier to distinguish ischemic stroke from non-ischemic stroke data. Five-fold cross-validation experiments demonstrated that the proposed model possesses excellent performance, with accuracy, sensitivity, and specificity reaching 90.17%, 89.86%, and 90.44%, respectively. Experiments on time consumption verified that the proposed method is superior to other state-of-the-art examinations. This study contributes to the advancement of the rapid detection of ischemic stroke, shedding light on the untapped potential of EEG and demonstrating the efficacy of deep learning in ischemic stroke identification.

Update on the anesthesia management in adult patients with moyamoya disease.

The anesthetic management of patients with Moyamoya disease (MMD) is challenging and continues to evolve. The goal of this review is to provide updated recommendations on the anesthetic management of adult MMD patients based on the relevant existing literature. Key findings include the importance of aggressive hydration preoperatively to sustain cerebral perfusion. Hypertension induced intraoperatively may prevent cerebral hypoperfusion. Vigilance against cerebral hyperperfusion after revascularization is necessary, with specific blood pressure targets recommended. Fluid management should aim for normovolemia to mild hypervolemia. Maintaining body temperature helps prevent cerebral vasospasm induced by hypothermia. Maintaining adequate oxygen supply during surgery is crucial. In cases of ischemic stroke, managing hematocrit and oxygen carrying capacity is essential to prevent further ischemia. Extubation decisions should consider baseline neurological function, while postoperative normocapnia helps prevent cerebral hyperperfusion and hypertension. In intensive care, cautious blood pressure management is crucial to prevent secondary complications. Strategies in the preoperative, intraoperative, and postoperative anesthetic management of MMD patients should aim to maintain adequate cerebral perfusion to prevent cerebral ischemia.

Short-Term Neurologic Complications in Patients Undergoing Extracorporeal Membrane Oxygenation Support: A Review on Pathophysiology, Incidence, Risk Factors, and Outcomes.

Regardless of the type, extracorporeal membrane oxygenation (ECMO) requires the use of large intravascular cannulas and results in multiple abnormalities including non-physiologic blood flow, hemodynamic perturbation, rapid changes in blood oxygen and carbon dioxide levels, coagulation abnormalities, and a significant systemic inflammatory response. Among other sequelae, neurologic complications are an important source of mortality and long-term morbidity. The frequency of neurologic complications varies and is likely underreported due to the high mortality rate. Neurologic complications in patients supported by ECMO include ischemic and hemorrhagic stroke, hypoxic brain injury, intracranial hemorrhage, and brain death. In addition to the disease process that necessitates ECMO, cannulation strategies and physiologic disturbances influence neurologic outcomes in this high-risk population. For example, the overall documented rate of neurologic complications in the venovenous ECMO population is lower, but a higher rate of intracranial hemorrhage exists. Meanwhile, in the venoarterial ECMO population, ischemia and global hypoperfusion seem to compose a higher percentage of neurologic complications. In what follows, the literature is reviewed to discuss the pathophysiology, incidence, risk factors, and outcomes related to short-term neurologic complications in patients supported by ECMO.

Increased adrenocortical activity in patients with vasovagal syncope

ObjectiveSyncope is a transient loss of consciousness resulting from cerebral hypoperfusion. Vasovagal syncope (VVS) is a form of orthostatic intolerance (OI). Its clinical signs such as dizziness and hypotension may mimic symptoms of adrenal insufficiency. The objective of this study was to evaluate the adrenal gland function in patients with vasovagal syncope after stimulation with synthetic adrenocorticotropic hormone (ACTH). DesignCase-control study on patients with VVS and healthy controls. MethodsThe study involved 42 participants, including 27 patients diagnosed with VVS using the head-up tilt test and 15 healthy individuals with no history of syncope or any orthostatic symptoms. Serum cortisol and aldosterone concentrations were measured under basal conditions and at 30 and 60 min after intramuscular ACTH stimulation. ResultsPatients with VVS had significantly higher cortisol levels at baseline (441 ± 143 vs. 331 ± 84.7 nmol/L, p = 0.01), at 30 min (802 ± 143 vs. 686 ± 105 nmol/L, p = 0.01) and at 60 min (931 ± 141 nmol/L vs. 793 ± 147 nmol/L, p = 0.001) after ACTH administration (Synacthen 250 μg). Plasma aldosterone increased after ACTH stimulation, but did not show significant differences among groups. Furthermore, there was also no significant correlation between cortisol levels and blood pressure or heart rate. ConclusionPatients diagnosed with VVS have higher cortisol levels both at baseline and after ACTH stimulation. This finding indicates that individuals with VVS have higher adrenocortical activity potentially as a response to the orthostatic stress induced by syncope, which acts as a stressful stimulus on the autonomic nervous system.

Multi-omics Study of Hypoxic-Ischemic Brain Injury After Cardiopulmonary Resuscitation in Swine

Evaluation of Neonatal Cerebral Circulation Under Hypoxic Ischemic Risk Factors Based on Quantitative Analysis of Cerebral Veins with Magnetic Resonance Susceptibility Weighted Imaging.

To observe the regulation of cerebral circulation in vivo based on image segmentation algorithms for deep learning in medical imaging to automatically detect and quantify the neonatal deep medullary veins (DMVs) on susceptibility weighted imaging (SWI) images. To evaluate early cerebral circulation self-rescue for neonates undergoing risk of cerebral hypoxia-ischaemia in vivo. SWI images and clinical data of 317 neonates with or without risk of cerebral hypoxia-ischaemia were analyzed. Quantitative parameters showing the number, width, and curvature of DMVs were obtained using an image segmentation algorithm. The number of DMVs was greater in males than in females (p < 0.01), and in term than in preterm infants (p = 0.001). The width of DMVs was greater in term than in preterm infants (p < 0.01), in low-risk than in high-risk group (p < 0.01), and in neonates without intracranial extracerebral haemorrhage (ICECH) than with ICECH (p < 0.05). The curvature of DMVs was greater in term than in preterm infants (P < 0.05). The width of both bilateral thalamic veins and anterior caudate nucleus veins were positively correlated with the number of DMVs; the width of bilateral thalamic veins was positively correlated with the width of DMVs. The DMVs quantification based on image segmentation algorithm may provide more detailed and stable quantitative information in neonate. SWI vein quantification may be an observable indicator for in vivo assessment of cerebral circulation self-regulation in neonatal hypoxic-ischemic brain injury.

Incidence and clinical analysis of asymptomatic intracranial hemorrhage in neonates with cerebral hypoxic-ischaemic risk based on multisequence MR images

The incidence and clinical distribution of intracranial haemorrhage (ICH) in neonates at risk of cerebral hypoxia–ischaemia have not been reported in specific studies. Based on conventional magnetic resonance imaging (MRI) versus susceptibility weighted imaging (SWI), this study aimed to analyse the occurrence of asymptomatic ICH in newborns with or without risk of cerebral hypoxia–ischaemia and to accumulate objective data for clinical evaluations of high-risk neonates and corresponding response strategies. 317 newborns were included. MRI revealed that the overall incidence of ICH was 59.31%. The most common subtype was intracranial extracerebral haemorrhage (ICECH) which included subarachnoid haemorrhage (SAH) and subdural haemorrhage (SDH). ICECH accounted for 92.02% of ICH. The positive detection rate of ICECH by SWI was significantly higher than that by T1WI. The incidence of total ICH, ICECH and SAH was greater among children who were delivered vaginally than among those who underwent caesarean delivery. Asymptomatic neonatal ICH may be a common complication of the neonatal birth process, and SWI may improve the detection rate. Transvaginal delivery and a weight greater than 2500 g were associated with a high incidence of ICECH in neonates. The impact of neonatal cerebral hypoxia–ischaemia risk factors on the occurrence of asymptomatic ICH may be negligible.

Enteral nutritional strategy during therapeutic hypothermia: who? when?what?

There are no guidelines regarding enteral feeding (EF) of infants with hypoxic-ischemic encephalopathy (HIE) during and shortly after therapeutic hypothermia; consequently, clinical practice is, to date, still variable. The objective of this study is to assess whether a minimal EF strategy during therapeutic hypothermia may be associated with a shorter time to full EF of infants with HIE and to identify the clinical variables that independently affect the time to full EF. A retrospective study, covering the period from 1 January 2015 to 30 June 2022 was performed at the Neonatal Intensive Care Unit of the Fondazione Policlinico Universitario "Agostino Gemelli" IRCCS, Rome, which compared infants with HIE who received minimal EF during therapeutic hypothermia with those who did not. Seventy-eight infants received minimal EF during therapeutic hypothermia, while 75 did not. Infants who were fed reached full EF significantly faster than those who were not. Moreover, they received parenteral nutrition and maintained central venous lines for a shorter time. A multivariate analysis, taking into account the variable of clinical severity, confirmed that minimal EF is an independent beneficial factor for reaching full EF in a shorter time and mechanical ventilation and seizures are independent factors for a longer time to full EF. Minimal EF during therapeutic hypothermia is associated with a shorter time to full EF in stable infants with HIE. Further prospective studies are needed to better define the enteral nutrition strategy for infants during therapeutic hypothermia, regardless of the severity of clinical conditions.

Neurosonographic Classification in Premature Infants Receiving Omega-3 Supplementation Using Convolutional Neural Networks.

This study focuses on developing a model for the precise determination of ultrasound image density and classification using convolutional neural networks (CNNs) for rapid, timely, and accurate identification of hypoxic-ischemic encephalopathy (HIE). Image density is measured by comparing two regions of interest on ultrasound images of the choroid plexus and brain parenchyma using the Delta E CIE76 value. These regions are then combined and serve as input to the CNN model for classification. The classification results of images into three groups (Normal, Moderate, and Intensive) demonstrate high model efficiency, with an overall accuracy of 88.56%, precision of 90% for Normal, 85% for Moderate, and 88% for Intensive. The overall F-measure is 88.40%, indicating a successful combination of accuracy and completeness in classification. This study is significant as it enables rapid and accurate identification of hypoxic-ischemic encephalopathy in newborns, which is crucial for the timely implementation of appropriate therapeutic measures and improving long-term outcomes for these patients. The application of such advanced techniques allows medical personnel to manage treatment more efficiently, reducing the risk of complications and improving the quality of care for newborns with HIE.
