RESUMEN
BACKGROUND: Admission cardiotocography (CTG), a noninvasive procedure, is used to indicate the state of oxygenation of the fetus on admission into the labor ward. OBJECTIVE: This study assessed the association of admission CTG findings with neonatal outcome at a tertiary health facility. MATERIALS AND METHODS: A prospective, observational study of 206 pregnant women who were admitted into the labor ward with singleton live pregnancies. Information on the demographic characteristics, obstetrics and medical history, admission CTG tracing, and neonatal outcome was obtained using a structured data collection form. Data were analyzed using the SPSS software version 20.0 with the level of significance set at P < 0.05. RESULTS: The admission CTG findings were normal in 73.3%, suspicious in 13.6%, and pathological in 13.1% of the women. The occurrence of low birth weight, special care baby unit (SCBU) admission, asphyxiated neonates, neonatal death, and prolonged hospital admission was significantly more frequent among those with pathological admission CTG results compared with normal and suspicious results (P < 0.05). The incidence of vaginal delivery was more common when the CTG findings were normal, whereas all women with pathological CTG result had a cesarean delivery. CONCLUSION: Admission CTG was effective in identifying fetuses with a higher incidence of perinatal asphyxia. Neonatal outcome such as low birth weight, APGAR score, SCBU admission, and prolonged hospital admission was significantly associated with pathological CTG findings. In the absence of facilities for further investigations, prompt intervention for delivery should be ensured if admission CTG is pathological.
Résumé Contexte:La cardiotocographie d'admission (CTG), une procédure non invasive, est utilisée pour indiquer l'état d'oxygénation du fÅtus lors de son admission en salle de travail.Objectif:Cette étude a évalué l'association entre les résultats du CTG à l'admission et l'issue néonatale dans un établissement de santé tertiaire.Matériels et méthodes:Une étude observationnelle prospective portant sur 206 femmes enceintes admises en salle de travail avec des grossesses vivantes uniques. Des informations sur les caractéristiques démographiques, les antécédents obstétricaux et médicaux, le traçage CTG à l'admission et les résultats néonatals ont été obtenues à l'aide d'un formulaire de collecte de données structuré. Les données ont été analysées à l'aide du logiciel SPSS version 20.0 avec le niveau de signification fixé à P <0,05.Résultats:Les résultats du CTG à l'admission étaient normaux chez 73,3 %, suspects chez 13,6 % et pathologiques chez 13,1 % des femmes. La survenue d'un faible poids à la naissance, d'une admission dans une unité de soins spéciaux pour bébés (SCBU), de nouveau-nés asphyxiés, de décès néonatals et d'une hospitalisation prolongée était significativement plus fréquente chez les personnes ayant des résultats CTG d'admission pathologiques par rapport aux résultats normaux et suspects (P < 0,05). L'incidence des accouchements par voie basse était plus fréquente lorsque les résultats du CTG étaient normaux, alors que toutes les femmes présentant un résultat pathologique du CTG avaient accouché par césarienne.Conclusion:L'admission CTG s'est avérée efficace pour identifier les fÅtus présentant une incidence plus élevée d'asphyxie périnatale. Les résultats néonatals tels qu'un faible poids à la naissance, le score APGAR, l'admission au SCBU et l'hospitalisation prolongée étaient significativement associés aux résultats pathologiques du CTG. En l'absence de moyens permettant des investigations plus approfondies, une intervention rapide pour l'accouchement doit être assurée si l'admission du CTG est pathologique.

Acute kidney injury (AKI) is characterized by a sudden decline in the kidneys' abilities to remove waste products and maintain water and electrolyte homeostasis. This study aims to determine the incidence and predictors of acute kidney injury among neonates with perinatal asphyxia admitted at the neonatal intensive care unit of West Amhara Comprehensive Specialized Hospital, Northwest Ethiopia, 2023. Multicentred institution-based retrospective follow-up study was conducted from October 1, 2021, to September 30, 2023, among 421 perinatal asphyxia neonates. A simple random sampling technique was used. The data were collected using a data extraction checklist from the medical registry of neonates. The collected data were entered into EPI-DATA V.4.6.0.0. and analyzed using STATA V.14. The Kaplan-Meier failure curve and log-rank test were employed. Bivariable and multivariable Cox regression was carried out to identify predictors of Acute kidney injury. Statistical significance was declared at a p ≤ 0.05. The overall incidence of AKI was 54 (95% CI 47.07-62.51) per 100 neonate days. C/S delivery (AHR = 0.64; (95% CI 0.43-0.94), prolonged labor (AHR = 1.43; 95% CI 1.03-1.99) low-birth weight times (AHR = 1.49; (95% CI 1.01-2.20), stage three HIE(AHR: 1.68; (95% CI (1.02-2.77), No ANC follow up (AHR = 1.43; 95% CI 1.9 (1.07-3.43) and Hyperkalemia (AHR = 1.56; 95% CI 1.56 (1.05-2.29); 95% CI) were significant predictors. The incidence rate of acute kidney injury was higher than in other studies conducted on other groups of neonates. Cesarean section delivery, prolonged low birthweight, no Anc follow-up, stage 3 HIE, and neonatal hyperkalemia were predictors of acute kidney injury. However, it needs further prospective study. Therefore, the concerned stakeholders should give due attention and appropriate intervention to these predictors.

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.

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.

OBJECTIVE: To determine the incidence and sociodemographic and clinical risk factors associated with birth asphyxia and the immediate neonatal outcomes of birth asphyxia in Nigeria. DESIGN: Secondary analysis of data from the Maternal and Perinatal Database for Quality, Equity and Dignity Programme. SETTING: Fifty-four consenting referral-level hospitals (48 public and six private) across the six geopolitical zones of Nigeria. POPULATION: Women (and their babies) who were admitted for delivery in the facilities between 1 September 2019 and 31 August 2020. METHODS: Data were extracted and analysed on prevalence and sociodemographic and clinical factors associated with birth asphyxia and the immediate perinatal outcomes. Multilevel logistic regression modelling was used to ascertain the factors associated with birth asphyxia. MAIN OUTCOME MEASURES: Incidence, case fatality rate and factors associated with birth asphyxia. RESULTS: Of the available data, 65 383 (91.1%) women and 67 602 (90.9%) babies had complete data and were included in the analysis. The incidence of birth asphyxia was 3.0% (2027/67 602) and the case fatality rate was 16.8% (339/2022). The risk factors for birth asphyxia were uterine rupture, pre-eclampsia/eclampsia, abruptio placentae/placenta praevia, birth trauma, fetal distress and congenital anomaly. The following factors were independently associated with a risk of birth asphyxia: maternal age, woman's education level, husband's occupation, parity, antenatal care, referral status, cadre of health professional present at the birth, sex of the newborn, birthweight and mode of birth. Common adverse neonatal outcomes included: admission to a special care baby unit (SCBU), 88.4%; early neonatal death, 14.2%; neonatal sepsis, 4.5%; and respiratory distress, 4.4%. CONCLUSIONS: The incidence of reported birth asphyxia in the participating facilities was low, with around one in six or seven babies with birth asphyxia dying. Factors associated with birth asphyxia included sociodemographic and clinical considerations, underscoring a need for a comprehensive approach focused on the empowerment of women and ensuring access to quality antenatal, intrapartum and postnatal care.

INTRODUCTION: Perinatal asphyxia is failure to maintain normal breathing at birth. World Health Organization indicates that perinatal asphyxia is the third major cause of neonatal mortality in developing countries accounting for 23% of neonatal deaths every year. At global and national level efforts have done to reduce neonatal mortality, however fatalities from asphyxia remains high in Ethiopia (24%). And there are no sufficient studies to show incidence and prediction of mortality among asphyxiated neonates. Developing validated risk prediction model is one of the crucial strategies to improve neonatal outcomes with asphyxia. Therefore, this study will help to screen asphyxiated neonate at high-risk for mortality during admission by easily accessible predictors. This study aimed to determine the incidence and develop validated Mortality Prediction model among asphyxiated neonates admitted to the Neonatal Intensive Care Unit at Felege-Hiwot Comprehensive Specialized Hospital, Bahir Dar, Ethiopia. METHOD: Retrospective follow-up study was conducted at Felege-Hiwot Comprehensive Specialized Hospital from September 1, 2017, to March 31, 2021. Simple random sampling was used to select 774 neonates, and 738 were reviewed. Since was data Secondary, it was collected by checklist. After the description of the data by table and graph, Univariable with p-value < 0.25, and stepwise multivariable analysis with p-value < 0.05 were done to develop final reduced prediction model by likelihood ratio test. To improve clinical utility, we developed a simplified risk score to classify asphyxiated neonates at high or low-risk of mortality. The accuracy of the model was evaluated using area under curve, and calibration plot. To measures all accuracy internal validation using bootstrapping technique were assessed. We evaluated the clinical impact of the model using a decision curve analysis across various threshold probabilities. RESULT: Incidence of neonatal mortality with asphyxia was 27.2% (95% CI: 24.1, 30.6). Rural residence, bad obstetric history, amniotic fluid status, multiple pregnancy, birth weight (< 2500 g), hypoxic-ischemic encephalopathy (stage II and III), and failure to suck were identified in the final risk prediction score. The area under the curve for mortality using 7 predictors was 0.78 (95% CI 0.74 to 0.82). With ≥ 7 cutoffs the sensitivity and specificity of risk prediction score were 0.64 and 0.82 respectively. CONCLUSION AND RECOMMENDATION: Incidence of neonatal mortality with asphyxia was high. The risk prediction score had good discrimination power built by rural residence, bad obstetric history, stained amniotic fluid, multiple pregnancy, birth weight (< 2500 g), hypoxic-ischemic encephalopathy (stage II and III), and failure to suck. Thus, using this score chart and improve neonatal and maternal service reduce mortality among asphyxiated neonates.

BACKGROUND: Perinatal asphyxia contributes significantly to neonatal morbidity and mortality. It occurs worldwide, and the Apgar score is the most widely used method of diagnosis. Recently, umbilical cord arterial pH has been reported as the most objective way to assess fetal acidosis at birth as it predicts the adverse outcome of perinatal asphyxia. It is imperative to establish the concordance between these two diagnostic methods to reinforce the practicality of the Apgar score as the preferred diagnostic tool for perinatal asphyxia in developing nations, such as Nigeria. AIM: To determine the prevalence of perinatal asphyxia by using the Apgar score and arterial cord blood pH and the relationships between these methods at the Federal Medical Center (FMC), Umuahia. MATERIALS AND METHODS: This cross-sectional study enrolled 245-term newborns. Perinatal asphyxia was diagnosed using both Apgar scoring and arterial cord blood pH measurements. Data obtained were analyzed using SPSS version 20 and a P value < 0.05 was considered significant. RESULTS: Perinatal asphyxia was reported in 33.1% and 31.4% by using the Apgar score and arterial cord blood pH, respectively. There was a moderate agreement between the two methods for diagnosing perinatal asphyxia (κ = 0.44), and no statistically significant difference was observed in the prevalence of perinatal asphyxia between these methods (McNemar's χ2 = 0.27, P = 0.699). Furthermore, a strong positive correlation was observed between the Apgar score at 1 and 5 minutes of life and arterial cord blood pH (rs = 0.87, P ≤ 0.001 and rs = 0.80, P ≤ 0.001 respectively). CONCLUSION: The prevalence of perinatal asphyxia by the two methods was high, and there was no significant difference between both methods of assessing perinatal asphyxia. Thus, the diagnosis of perinatal asphyxia can effectively be made using either the Apgar score or arterial cord blood pH, affirming the practicality and reliability of the Apgar score in resource-limited healthcare settings.

BACKGROUND: Birth asphyxia is the main cause of neonatal mortality and morbidity worldwide. Some studies indicate intimate partner violence during pregnancy is a risk factor for birth asphyxia. In Ethiopia, intimate partner violence during pregnancy is reported to be high. Despite this high prevalence, there is a lack of data about the association of birth asphyxia and intimate partner violence. The aim of this study was to assess the prevalence of intimate partner violence during pregnancy and its associated factors with birth asphyxia in health facilities in the Tigray region of northern Ethiopia. METHODS: This was an institutional-based cross-sectional study conducted at select health facilities in the Tigray region of Ethiopia. Random sampling technique was employed to select health facilities and systematic sampling was used to select 648 study participants. Data was entered by using Epi info version 3.5.1 and was analyzed using SPSS version 20. Bivariate and multivariate analysis was done to assess the association between exposure to intimate partner violence during pregnancy and birth asphyxia after adjusting for possible confounders. RESULTS: The prevalence of intimate partner violence during pregnancy was 47(7.3%). Eighty two (12.7%) babies were delivered with birth asphyxia. Intimate partner violence during pregnancy had a significant association with birth asphyxia, AOR (95% CI) = 4.4(2-9.8). In addition to this, other factors that were associated with birth asphyxia include place of residence [ AOR (95% CI) = 2.7(1.55-4.8)], age > 19 [AOR (95% CI) = 2.9(1.29-6.5)], age 20-35 [AOR (95% CI) = 3.1(1.06-9.3)], gestational age < 37 weeks [AOR(95% CI) = 7.2(3.5-14.8)] and low birth weight [AOR(95% CI) = 3.9(2.1-7.3)]. CONCLUSIONS: The prevalence of birth asphyxia in this study is high and is further increased by intimate partner violence during pregnancy. Health care providers and policy makers should take measures aimed at preventing intimate partner violence during pregnancy to reduce harm to the mother and adverse birth outcomes.

Introduction: Birth asphyxia causes significant morbidity and mortality among neonates, especially in low-income and middle-income countries like Nepal. However, there is a paucity of data regarding its burden. This study aimed to find the prevalence of birth asphyxia among neonates admitted to the neonatal intensive care unit of a tertiary care hospital. Methods: This descriptive cross-sectional study was conducted among neonates at a tertiary care hospital between 15 January 2022 to 14 January 2023 after obtaining ethical approval from the Institutional Review Committee. Neonates with gestational age ≥35 weeks were included and those with major congenital anomalies were excluded. A convenience sampling method was used. A point estimate was calculated at a 95% Confidence Interval. Results: Among 902 neonates, 120 (13.30%) (11.08-15.52, 95% Confidence Interval) had birth asphyxia. A total of 108 (90%) were outborn, and 84 (70%) were males. HIE stage-I, II and III were seen in 47 (39.17%), 64 (53.33%) and 9 (7.50%) of the asphyxiated neonates respectively. Poor suck 92 (76.67%), seizures 73 (60.83%) and lethargy 70 (58.33%) were common abnormal neurological findings. Death occurred in 15 (12.50%) neonates in the hospital. Conclusions: The prevalence of birth asphyxia was found to be similar to other studies done in similar settings. The high burden underscores an urgent need to implement better perinatal care and delivery room management practices. Keywords: hypoxic-ischemic encephalopathy; neonates; prevalence.

Introduction: Perinatal asphyxia is a very common cause of morbidity and mortality in both term and preterm neonates and ranks the second most important cause of neonatal death. The incidence and importance of acute kidney injury in the neonatal period are becoming increasingly apparent. Early diagnosis and timely management of acute kidney injury is very important in these newborns to avoid other long-term adverse events. This study aimed to find out the prevalence of acute kidney injury among neonates with perinatal asphyxia in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted at the neonatal intensive care unit and nursery in a tertiary care hospital of Eastern Nepal from 1 November 2021 to 31 October 2022 after obtaining ethical approval from the Institutional Review Committee. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 97 neonates, the prevalence of acute kidney injury was seen among 60 (61.86%) (50.25-69.75, 95% Confidence Interval) neonates. Out of which 42 (70%) were males and 18 (30%) were female. Conclusions: The prevalence of acute kidney injury among neonates with perinatal asphyxia was found to be higher than other studies done in a similar setting. Keywords: acute kidney injury; neonates; prevalence.

BACKGROUND: Neonatal asphyxia is one of preventable causes of neonatal mortality throughout the world. It could be improved by early detection and control of the underlying causes. However, there was lack of evidence on it in the study setting. Thus, the aim of this study was to assess the magnitude and predictors of neonatal asphyxia among newborns at public hospitals of Wolaita Zone in Southern Ethiopia. METHOD: A facility-based cross-sectional study was done among 330 mothers with neonates in selected public hospitals. A systematic random sampling technique was used to select the study participants. Data were collected through an interviewer-administered questionnaire and checklist. The collected data were entered into EpiData version 4.6 and exported to SPSS version 26 for analysis. Logistic regression was fitted to examine the association between explanatory variables and outcome variable. In multivariable logistic regression, AOR with 95% CI was reported, and p < 0.05 was used to declare statistically significant variables. RESULTS: The magnitude of neonatal asphyxia was 26.4% with 95% CI: (21.8, 30.9). In multivariable logistic regression analysis primiparity (AOR = 2.63 95%CI 1.47, 4.72), low-birth-weight (AOR = 3.45 95%CI 1.33, 8.91), preterm birth (AOR = 3.58 95%CI 1.29, 9.92), and premature rupture of membranes (AOR = 5.19 95%CI 2.03, 13.26) were factors significantly associated with neonatal asphyxia. CONCLUSIONS: In this study, the magnitude of neonatal asphyxia was high. From the factors, premature rapture of the membrane, parity, birth weight of the newborn, and gestational age at birth were significantly associated with neonatal asphyxia. Attention should be given to early detection and prevention of neonatal asphyxia from complicated labor and delivery.

PURPOSE: To analyze the association between risk factors and severe intraventricular hemorrhage (grade II-IV) in PNB under 1500 g. METHODS: Multicenter, retrospective, analytical, case-control study in PNB under 34 weeks and under 1500 g admitted to the NICU. CASE: PNB with severe intraventricular hemorrhage (grade II-IV). Logistic regression analysis was used to adjust for IVH-associated variables and odds ratios (OR). RESULTS: A total of 90 PNB files were analyzed, 45 cases and 45 controls. The highest risk factors for severe IVH were lower gestational age (OR 1.3, p < 0.001), perinatal asphyxia (OR 12, p < 0.001), Apgar < 6 at minute 1 and 5 (OR 6.3, p < 0.001). CONCLUSION: Lower gestational age, birth asphyxia, Apgar score lower of 6, and respiratory-type factors are associated with increased risk for severe IVH.

INTRODUCTION: Birth asphyxia is a leading cause of neonatal mortality in sub-Saharan Africa. The relationship to grand multiparity (GM), a controversial pregnancy risk factor, remains largely unexplored, especially in the context of large multinational studies. We investigated birth asphyxia and its association with GM and referral in Benin, Malawi, Tanzania and Uganda. MATERIAL AND METHODS: This was a prospective cross-sectional study. Data were collected using a perinatal e-Registry in 16 hospitals (four per country). The study population consisted of 80 663 babies (>1000 g, >28 weeks' gestational age) delivered between July 2021 and December 2022. The primary outcome was birth asphyxia, defined by 5-minute appearance, pulse, grimace, activity and respiration score <7. A multilevel and stratified multivariate logistic regression was performed with GM (parity ≥5) as exposure, and birth asphyxia as outcome. An interaction between referral (none, prepartum, intrapartum) and GM was also evaluated as a secondary outcome. All models were adjusted for confounders. CLINICAL TRIAL: Pan African Clinical Trial Registry 202006793783148. RESULTS: Birth asphyxia was present in 7.0% (n = 5612) of babies. More babies with birth asphyxia were born to grand multiparous women (11.9%) than to other parity groups (≤7.6%). Among the 76 850 cases included in the analysis, grand multiparous women had a 1.34 times higher odds of birth asphyxia (95% confidence interval [CI] 1.17-1.54) vs para one to two. Grand multiparous women referred intrapartum had the highest probability of asphyxiation (13.02%, 95% CI 9.34-16.69). GM increased odds of birth asphyxia in Benin (odds ratio [OR] 1.37, 95% CI 1.13-1.68) and Uganda (OR 1.29, 95% CI 1.02-1.64), but was non-significant in Tanzania (OR 1.44, 95% CI 0.81-2.56) and Malawi (OR 0.98, 95% CI 0.67-1.44). CONCLUSIONS: There is some evidence of an increased risk of birth asphyxia for grand multiparous women having babies at hospitals, especially following intrapartum referral. Antenatal counseling should recognize grand multiparity as higher risk and advise appropriate childbirth facilities. Findings in Malawi suggest an advantage of health systems configuration requiring further exploration.

The purpose of this study is to evaluate the association between perinatal asphyxia, neonatal encephalopathy, and childhood hearing impairment. This is a population-based study including all Norwegian infants born ≥ 36 weeks gestation between 1999 and 2014 and alive at 2 years (n = 866,232). Data was linked from five national health registries with follow-up through 2019. Perinatal asphyxia was defined as need for neonatal intensive care unit (NICU) admission and an Apgar 5-min score of 4-6 (moderate) or 0-3 (severe). We coined infants with seizures and an Apgar 5-min score < 7 as neonatal encephalopathy with seizures. Infants who received therapeutic hypothermia were considered to have moderate-severe hypoxic-ischemic encephalopathy (HIE). The reference group for comparisons were non-admitted infants with Apgar 5-min score ≥ 7. We used logistic regression models and present data as adjusted odds ratios (aORs) with 95% confidence intervals (CI). The aOR for hearing impairment was increased in all infants admitted to NICU: moderate asphyxia aOR 2.2 (95% CI 1.7-2.9), severe asphyxia aOR 5.2 (95% CI 3.6-7.5), neonatal encephalopathy with seizures aOR 7.0 (95% CI 2.6-19.0), and moderate-severe HIE aOR 10.7 (95% CI 5.3-22.0). However, non-admitted infants with Apgar 5-min scores < 7 did not have increased OR of hearing impairment. The aOR for hearing impairment for individual Apgar 5-min scores in NICU infants increased with decreasing Apgar scores and was 13.6 (95% CI 5.9-31.3) when the score was 0. Conclusions: An Apgar 5-min score < 7 in combination with NICU admission is an independent risk factor for hearing impairment. Children with moderate-severe HIE had the highest risk for hearing impairment. What is Known: ⢠Perinatal asphyxia and neonatal encephalopathy are associated with an increased risk of hearing impairment. ⢠The strength of the association, and how other co-morbidities affect the risk of hearing impairment, is poorly defined. What is New: ⢠Among neonates admitted to a neonatal intensive care unit (NICU), decreased Apgar 5-min scores, and increased severity of neonatal encephalopathy, were associated with a gradual rise in risk of hearing impairment. ⢠Neonates with an Apgar 5-min score 7, but without NICU admission, did not have an increased risk of hearing impairment.

Studies in infants with hypoxic-ischemic encephalopathy (HIE) due to perinatal asphyxia have generally focused on neurological outcomes. Although acute kidney injury (AKI) rate decreased in advent of therapeutic hypothermia (TH), it is still a common and important entity. In this retrospective study, we aimed to investigate the risk factors for AKI in HIE patients treated with hypothermia. Infants treated with TH due to HIE were reviewed retrospectively and infants who developed AKI and not were compared. Ninety-six patients were enrolled in the study. AKI developed in 27 (28%) patients and 4 (14.8%) of them were stage III AKI. In the AKI group, gestational age of the patients was significantly higher (p = 0.035), the 1st minute Apgar score was significantly lower (p = 0.042), and convulsions (p = 0.002), amplitude-integrated electroencephalography disorders (p = 0.025), sepsis (p = 0.017), need for inotropic therapy (p = 0.001), need of invasive mechanical ventilation (p = 0.03), and systolic dysfunction in echocardiography (p = 0.022) were significantly higher. In logistic regression tests, Apgar score at the 1st minute was found to be independent risk factor for developing AKI. AKI has the potential to worsen the neurological damage and correlates with morbidities of perinatal asphyxia. It is important to determine the incidence and risk factors for developing AKI in this delicate group of patients to prevent further renal damage.

As the major public health problem among under-5 children in the world, neonatal asphyxia (NA) contributes to 24% of the main causes of neonatal death. The effects of NA is not only limited to death but also has a long-term brain injury with lifelong adverse effects. Therefore, the goal of this study was to identify determinants of NA among newborns in the tropical province of China to guide early interventions and improve the survival and quality of life of these infants. A case control study was conducted at Hainan Women and Children's Medical Center from January 1 to December 31, 2021. A total of 255 newborns (85 cases and 170 controls, 1:2 case to control ratio) were enrolled in the study. A systematic random sampling approach was adopted based on hospital delivery registration. Structured questionnaires were used to collected data. The data was entered into statistical software SPSS version 20.0 for analysis. In the bivariable analysis, variables with P values less than .1 were entered into multivariable logistic regression analysis. At a P value of .05, a statistically significant level was reported. Amniotic fluid stained by meconium/blood (AORâ =â 3.19, 95% confidence interval [CI]: 1.47-6.95), primiparity, fetal presentation of malpresentation (AORâ =â 3.89, 95% CI: 1.25-12.09), and low birth weight (AORâ =â 10.51, 95% CI: 3.02-36.55) were to be significantly associated with NA. This study identified that amniotic fluid stained by meconium/blood, primiparity, low birth weight were determinants of NA. Thus, preventive solutions such as close monitoring of fetus presentation, meliorating the obstetric care setup during antenatal care consultations should be stressed in China.

Consanguinity commonly known as inbreeding is a state of offspring borne to couple sharing same ancestors. It is a least researched non-obstetric determinant of adverse birth outcome in developing countries like Pakistan. This hospital based study was designed to investigate the association between consanguineous status and neonatal asphyxia measured measured as low APGAR scores after birth in 879 newborns.The data regarding consanguineous status was obtained retrospectively. Potential covariates were incorporated for finding confounding effects. Data was analyzed in SPSS version 26.0 as mean ± standard deviation, unadjusted & adjusted odds ratios by logistic regression at P-values ≤ 0.05 significance for associations. Over 36.1% newborns were consanguineous, delivered with APGAR < 6 at 1-minute compared to 5.2% born to non-consanguineous parents. Premature birth was the single most important factor associated with neonatal asphyxia and low APGAR at 1 & 5-minute after birth. After adjusting for confounding variables, first cousin couples' offsprings showed OR of 9.1 & 4.1 for APGAR score ≤ 6 at 1 & 5-minutes after birth, respectively (P < 0.001 & P =0.001). We conclude that consanguinity is a strong determinant for neonatal asphyxia reported as low APGAR scores in this population of new borns.

Neonatal seizures are common in newborn infants after birth asphyxia. They occur more frequently in male than female neonates, but it is not known whether sex also affects seizure severity or duration. Furthermore, although stress and diurnal, ultradian, circadian, or multidien cycles are known to affect epileptic seizures in adults, their potential impact on neonatal seizures is not understood. This prompted us to examine the effects of season, daytime, sex, and stress on neonatal seizures in a rat model of birth asphyxia. Seizures monitored in 176 rat pups exposed to asphyxia on 40 experimental days performed over 3 years were evaluated. All rat pups exhibited seizures when exposed to asphyxia at postnatal day 11 (P11), which in terms of cortical development corresponds to term human babies. A first examination of these data indicated a seasonal variation, with the highest seizure severity in the spring. Sex and daytime did not affect seizure characteristics. However, when rat pups were subdivided into animals that were exposed to acute (short-term) stress after asphyxia (restraint and i.p. injection of vehicle) and animals that were not exposed to this stress, the seizures in stress-exposed rats were more severe but less frequent. Acute stress induced an increase in hippocampal microglia density in sham-exposed rat pups, which may have an additive effect on microglia activation induced by asphyxia. When seasonal data were separately analyzed for stress-exposed vs. non-stress-exposed rat pups, no significant seasonal variation was observed. This study illustrates that without a detailed analysis of all factors, the data would have erroneously indicated significant seasonal variability in the severity of neonatal seizures. Instead, the study demonstrates that even mild, short-lasting postnatal stress has a profound effect on asphyxia-induced seizures, most likely by increasing the activity of the hypothalamic-pituitary-adrenal axis. It will be interesting to examine how postnatal stress affects the treatment and adverse outcomes of birth asphyxia and neonatal seizures in the rat model used here.

Background: The passage of meconium during labor increased the chance of undesirable birth outcomes. The adverse effects of meconium are worsening in resource-limited countries. In Ethiopia, there is an argument concerning meconium's negative effects and management on pregnant women and their babies. Therefore, this study was intended to assess the adverse maternal and perinatal outcomes of meconium in term labor in the South Gondar Zone, Ethiopia. Methods: A prospective cohort study was conducted using 580 laboring mothers (145 exposed and 435 nonexposed groups). A two-stage sampling method was implemented to get study subjects. The data were collected using an interviewer-administered structured questionnaire and a medical chart review. SPSS version 25 was used for data analysis. Chi-squared and Fisher's exact tests were used to compare the two groups' differences. The strength of the association was measured using relative risk with a 95% CI. Result: There was more operative delivery (28.3% versus 5.3%), puerperal sepsis (79.54% versus 2.06%), nonreassuring fetal heart rate pattern (29.7% versus 2.1%), meconium aspiration syndrome (7.58% versus 0.68%), neonatal sepsis (9% versus 4.1%), perinatal asphyxia (13.8% versus 7.6%), admission to the neonatal intensive care unit (23.4% versus 3.2%), and early neonatal deaths (4.8% versus 1.4%) among meconium stained groups as compared to the clear amniotic fluid groups. Conclusion: Meconium-stained amniotic fluid significantly increased adverse maternal and perinatal outcomes in Ethiopia. The risk of perinatal asphyxia, nonreassuring fetal heart rate pattern, neonatal sepsis, meconium aspiration syndrome, admission to the NICU, early neonatal death, operative delivery, and puerperal sepsis were significantly higher in meconium-exposed groups. Special attention should be given to meconium-exposed mothers during the intrapartum period and in postnatal follow-up.
