BACKGROUND
Despite medical advancements in neonatal survival rates, many children have poor neurological outcomes. Because the law in Korea restricts the withdrawal of life-sustaining treatment to only cases of imminent death, treatment discontinuation may not be an option, even in patients with poor neurological prognosis. This study investigated the opinions of the general population and clinicians regarding life-sustaining treatment withdrawal in such cases using hypothetical scenarios.
METHODS
We conducted a cross-sectional study on the general population and clinicians using a web-based questionnaire. The sample of the general population from an online panel comprised 500 individuals aged 20-69 years selected by quota sampling. The clinician sample comprised 200 clinicians from a tertiary university hospital. We created hypothetical vignettes and questionnaire items to assess attitudes regarding mechanical ventilation withdrawal for an infant at risk of poor neurological prognosis due to birth asphyxia at 2 months and 3 years after the incidence.
RESULTS
Overall, 73% of the general population and 74% of clinicians had positive attitudes toward mechanical ventilator withdrawal at 2 months after birth asphyxia. The proportion of positive attitudes toward mechanical ventilator withdrawal was increased in the general population (84%, < 0.001) and clinicians (80.5%, = 0.02) at 3 years after birth asphyxia. Religion, spirituality, the presence of a person with a disability in the household, and household income were associated with the attitudes of the general population. In the multivariable logistic regression analysis of the general population, respondents living with a person with a disability or having a disability were more likely to find the withdrawal of the ventilator at 2 months and 3 years after birth asphyxia not permissible. Regarding religion, respondents who identified as Christians were more likely to find the ventilator withdrawal at 2 months after birth asphyxia unacceptable.
CONCLUSION
The general population and clinicians shared the perspective that the decision to withdraw life-sustaining treatment in infants with a poor neurological prognosis should be considered before the end of life. A societal discussion about making decisions centered around the best interest of pediatric patients is warranted.

BACKGROUND
The burden of perinatal asphyxia remains high in our environment and when asphyxia is severe, vital organs are affected, with resultant multiorgan hypoxic-iscahemic injury to the heart, the brain, adrenals and other organs.
STUDY AIM
To evaluate for myocardial injury in asphyxiated term neonates with hypoxic ischaemic encephalopathy using serum cardiac troponin-I (cTnI).
METHODS
The study was a hospital-based descriptive cross-sectional study involving sixty term asphyxiated neonates and sixty gestational age-and sex-matched controls. The subjects were term neonates with five-minute Apgar score ≤ 6 and HIE while the controls were healthy term neonates with five-minute Apgar score > 6. Five-minute Apgar score was utilized to classify asphyxia into mild, moderate and severe asphyxia. The degree of encephalopathy was determined by modified Sarnat and Sarnat criteria. The serum cTnI was measured in subjects and controls at 12-24 hours of life using Enzyme-linked immunosorbent assay technique. The serum bilirubin levels were also measured in participants to exclude hyperbilirubinemia.
RESULTS
The median serum cTnI levels was significantly higher in the subjects (0.56ng/mL; 0.25-0.94ng/mL) than in the controls (0.50ng/mL; 0.00-0.67ng/mL), respectively; p=0.001. Similarly, the median serum cTnI level in HIE stage II (0.56ng/mL; 0.38-0.72ng/mL) or III (0.56ng/ml; 0.50-0.94ng/mL) was also significantly higher than the median value in HIE stage I (0.38ng/mL;0.25-0.72ng/mL) or in controls (0.50ng/mL; 0.00-0.67ng/mL); p<0.001. There was significant positive correlation between serum cTnI levels and severity of HIE in asphyxiated neonates (rs = 0.505, p < 0.001).
CONCLUSION
serum cTnI levels were elevated in severely asphyxiated neonates with HIE. The concentration of serum cTnI demonstrated significant positive correlation with HIE severity. Hence, the presence of HIE in asphyxiated neonates should prompt an evaluation for myocardial injury using serum cTnI. Any derangement noted should warrant instituting cardiovascular support in order to improve outcome and reduce asphyxia-related mortality.

Birth asphyxia is a potential cause of death that is also associated with acute and chronic morbidities. The traditional and immediate approach for monitoring birth asphyxia (i.e., arterial blood gas analysis) is highly invasive and intermittent. Additionally, alternative noninvasive approaches such as pulse oximeters can be problematic, due to the possibility of false and erroneous measurements. Therefore, further research is needed to explore alternative noninvasive and accurate monitoring methods for asphyxiated neonates. This study aims to investigate the prominent ECG features based on pH estimation that could potentially be used to explore the noninvasive, accurate, and continuous monitoring of asphyxiated neonates. The dataset used contained 274 segments of ECG and pH values recorded simultaneously. After preprocessing the data, principal component analysis and the Pan-Tompkins algorithm were used for each segment to determine the most significant ECG cycle and to compute the ECG features. Descriptive statistics were performed to describe the main properties of the processed dataset. A Kruskal-Wallis nonparametric test was then used to analyze differences between the asphyxiated and non-asphyxiated groups. Finally, a Dunn-Šidák post hoc test was used for individual comparison among the mean ranks of all groups. The findings of this study showed that ECG features (T/QRS, T Amplitude, Tslope, Tslope/T, Tslope/|T|, HR, QT, and QTc) based on pH estimation differed significantly ( < 0.05) in asphyxiated neonates. All these key ECG features were also found to be significantly different between the two groups.

BACKGROUND
Speech and language delay among children can result in social interaction problems, attention difficulties, decreased writing and reading abilities, and poor cognitive and behavioral development. Despite the mounting prevalence of speech and language delays in Ethiopia, there is a lack of literature addressing the factors contributing to this delay. Consequently, this study aims to identify determinants of speech and language delay among children aged 12 months to 12 years at Yekatit 12 Hospital in Addis Ababa, Ethiopia.
METHODS
We conducted an institutional-based at Yekatit 12 Hospital, unmatched case-control study with 50 cases and 100 controls aged 12 months to 12 years. Interviewer-administered questionnaires were used to collect data from the parents or caregivers of the participating children. Epi Info v7 was used for sample calculation, and SPSS v26 was used for analysis. The chi-square test was performed to determine the relationship between speech and language delay and determining factors, which was then followed by logistic regression. The significant determining factors were identified based on the adjusted odds ratio (AOR), with a 95% CI and p-value (< 0.05).
RESULTS
Case group constituted 23 males and 27 females, totaling 50 children. Upon completing the multivariate analysis, birth asphyxia [AOR = 4.58, 95CI (1.23-16.99)], bottle-feeding [AOR = 4.54, 95CI (1.29-16.04)], mother-child separation [AOR = 2.6, 95CI (1.05-6.43)], multilingual family [AOR = 2.31, 95CI (1.03-5.18)], and screen time greater than two hours [AOR = 3.06, 95CI (1.29-7.28)] were found to be statistically significant determinants of speech and language delay.
CONCLUSIONS
Our study found that birth asphyxia, bottle-feeding, mother-child separation, being from a multilingual family, and excessive screen time contribute significantly to speech and language delay. As a result, it is important to develop interventions that target these modifiable factors, while also ensuring that early diagnosis and treatment options are readily accessible.

BACKGROUND
Peripartum asphyxia is one of the main causes of neonatal morbidity and mortality. In moderate and severe cases of asphyxia, a condition called hypoxic-ischemic encephalopathy (HIE) and associated permanent neurological morbidities may follow. Due to the multifactorial etiology of asphyxia, it may be difficult prevent, but in term neonates, therapeutic cooling can be used to prevent or reduce permanent brain damage. The aim of this study was to assess the significance of different antenatal and delivery related risk factors for moderate and severe HIE and the need for therapeutic hypothermia.
METHODS
We conducted a retrospective matched case-control study in Helsinki University area hospitals during 2013-2017. Newborn singletons with moderate or severe HIE and the need for therapeutic hypothermia were included. They were identified from the hospital database using ICD-codes P91.00, P91.01 and P91.02. For every newborn with the need for therapeutic hypothermia the consecutive term singleton newborn matched by gender, fetal presentation, delivery hospital, and the mode of delivery was selected as a control. Odds ratios (OR) between obstetric and delivery risk factors and the development of HIE were calculated.
RESULTS
Eighty-eight cases with matched controls met the inclusion criteria during the study period. Maternal and infant characteristics among cases and controls were similar, but smoking was more common among cases (aOR 1.46, CI 1.14-1.64, p = 0.003). The incidence of preeclampsia, diabetes and intrauterine growth restriction in groups was equal. Induction of labour (aOR 3.08, CI 1.18-8.05, p = 0.02) and obstetric emergencies (aOR 3.51, CI 1.28-9.60, p = 0.015) were more common in the case group. No difference was detected in the duration of the second stage of labour or the delivery analgesia.
CONCLUSIONS
Smoking, induction of labour and any obstetric emergency, especially shoulder dystocia, increase the risk for HIE and need for therapeutic hypothermia. The decisions upon induction of labour need to be carefully weighed, since maternal smoking and obstetric emergencies can hardly be controlled by the clinician.

Observational Study
INTRODUCTION
Preterm birth complications and neonatal asphyxia are the leading causes of neonatal mortality worldwide. Surviving preterm and asphyxiated newborns can develop neurological sequelae; therefore, timely and appropriate neonatal resuscitation is important to decrease neonatal mortality and disability rates. There are very few systematic studies on neonatal resuscitation in China, and its prognosis remains unclear. We established an online registry for neonatal resuscitation in Shenzhen based on Utstein's model and designed a prospective, multicentre, open, observational cohort study to address many of the limitations of existing studies. The aim of this study is to explore the implementation and management, risk factors and outcomes of neonatal resuscitation in Shenzhen.
METHODS AND ANALYSIS
This prospective, multicentre, open, observational cohort study will be conducted between January 2024 and December 2026 and will include >1500 newborns resuscitated at birth by positive pressure ventilation at five hospitals in Shenzhen, located in the south-central coastal area of Guangdong province, China. Maternal and infant information, resuscitation information, hospitalisation information and follow-up information will be collected. Maternal and infant information, resuscitation information and hospitalisation information will be collected from the clinical records of the patients. Follow-up information will include the results of follow-up examinations and outcomes, which will be recorded using the WeChat applet 'Resuscitation Follow-up'. These data will be provided by the neonatal guardians through the applet on their mobile phones. This study will provide a more comprehensive understanding of the implementation and management, risk factors and outcomes of neonatal resuscitation in Shenzhen; the findings will ultimately contribute to the reduction of neonatal mortality and disability rates in Shenzhen.
ETHICS AND DISSEMINATION
Our protocol has been approved by the Medical Ethics Committee of Shenzhen Luohu People's Hospital (2023-LHQRMYY-KYLL-048). We will present the study results at academic conferences and peer-reviewed paediatrics journals.

The Rice-Vannucci model in rodent pups is subject to substantial loss of animals, result inconsistency, and high lab-to-lab variability in extent and composition of induced injury. This protocol allows for highly predictable and reproducible hypoxic-ischemic cerebral injury lesions in post-natal day 10 Wistar rat pups with no mortality. We describe steps for common carotid artery ligation, brief post-operative normothermia, exposure to hypoxia, and post-hypoxic normothermia. Precise timing and temperature control in each step are crucial for a successful procedure. For complete details on the use and execution of this protocol, please refer to Hartman et al..

Archives of Gynecology and Obstetrics Jul 2024To compare perinatal outcomes between active and routine management in true knot of the umbilical cord (TKUC). (Comparative Study)
Comparative Study
PURPOSE
To compare perinatal outcomes between active and routine management in true knot of the umbilical cord (TKUC).
METHODS
A retrospective study of singletons born beyond 22 weeks with TKUC. Active management included weekly fetal heart rate monitoring(FHRM) ≥ 30 weeks and labor induction at 36-37 weeks. Outcomes in active and routine management were compared, including composite asphyxia-related adverse outcome, fetal death, labor induction, Cesarean section (CS) or Instrumental delivery due to non-reassuring fetal heart rate (NRFHR), Apgar score < 7, cord Ph < 7, neonatal intensive care unit (NICU) admission and more.
RESULTS
The Active (n = 59) and Routine (n = 1091) Management groups demonstrated similar rates of composite asphyxia-related adverse outcome (16.9% vs 16.8%, p = 0.97). Active Management resulted in higher rates of labor induction < 37 weeks (22% vs 1.7%, p < 0.001), CS (37.3% vs 19.2%, p = 0.003) and NICU admissions (13.6% vs 3%, p < 0.001). Fetal death occurred exclusively in the Routine Management group (1.8% vs 0%, p = 0.6).
CONCLUSION
Compared with routine management, weekly FHRM and labor induction between 36 and 37 weeks in TKUC do not appear to reduce neonatal asphyxia. In its current form, active management is associated with higher rates of CS, induced prematurity and NICU admissions. Labor induction before 37 weeks should be avoided.

INTRODUCTION
Hypoxic-ischaemic encephalopathy is a clinical syndrome of neurological dysfunction that occurs immediately after birth following an episode of perinatal asphyxia. We conducted a scoping review to assess the methodological quality of clinical practice guidelines that address this condition.
METHODOLOGY
We conducted the evaluation using the AGREE II tool. High methodological quality was defined as a score greater than 70% in every domain.
RESULTS
The analysis included three clinical practice guidelines; the highest scores were in the scope and purpose domain (84.26%; SD, 14.25%) and the clarity of presentation domain (84.26%; SD, 17.86%), while the lowest score corresponded to the applicability domain (62.50%; SD, 36.62%). Two guidelines were classified as high quality and one guideline as low-quality.
CONCLUSIONS
Two of the assessed guidelines were classified as being of high quality; however, the analysis identified shortcomings in the applicability domain, in addition to methodological variation between guidelines developed in middle- or low-income countries versus high-income countries. Efforts are needed to make high-quality guidelines available to approach the management of hypoxic-ischaemic encephalopathy in newborns.

A retrospective data analysis on prevalence and risk factors for hypothermia among sick neonates at presentation to the neonatal intensive care unit of the Tamale Teaching Hospital.
Neonatal hypothermia, defined as an axillary temperature of <36.5C in a neonate, is common in neonatal intensive care units and is almost universal across all geographic and climatic regions of the world. This is even though environmental temperature is a known risk factor for its occurrence. We conducted a retrospective study in the Neonatal Intensive Care Unit of the Tamale Teaching Hospital (TTH) to document the prevalence and risk factors associated with hypothermia at presentation to the hospital. The study spanned the period from January 2019 to December 2019 and involved all neonates with axillary temperature documented at the time of admission. The prevalence of neonatal hypothermia in this study was 54.76%. Hypothermia was most common in neonates diagnosed with meconium aspiration syndrome (87/105, 82.86%), prematurity and low birth weight (575/702, 81.91%), and birth asphyxia (347/445, 77.98%). Neonates who were delivered vaginally were less likely to develop hypothermia compared to those delivered via Cesarean section. Inborn neonates (delivered in TTH) were 3.2 times more likely to be hypothermic when compared to those who were delivered at home. Neonates with low birth weight and APGAR scores < 7 at 1 and 5 minutes were more likely to be hypothermic. The dry season was found to be protective against hypothermia when compared to the rainy season. The overall mortality rate was 13.68% and the mortality in the subgroup with hypothermia at presentation was 18.87%. Our study documented a high prevalence of hypothermia with higher rates in neonates requiring intervention at birth. It is therefore crucial for perinatal care providers to adhere to the warm chain precautions around the time of birth.
