RESUMO

As a rare obstetric disease, fetomaternal hemorrhage (FMH) often causes severe fetal anemia, edema and even death, easily to be confused with severe neonatal asphyxia. Currently, there are several ways to detect or predict FMH, however, most of them are flawed and time-consuming, as well as unsuitable for rapid diagnosis and timely intervention of FMH. To explore the values of umbilical artery blood gas analysis in the rapid diagnosis of FMH, providing basis for rapid guidance of newborn rescue. Five cases of neonates with FMH from the First Affiliated Hospital of Army Military Medical University (Chongqing Southwest Hospital) from January 2013 to January 2016 were selected as the study group. Another 9 cases of severe asphyxia neonates were chosen into the control group. The difference in Apgar score and umbilical artery blood gas analysis between the 2 groups at birth was compared, and the treatments and clinical outcomes of the 2 groups were analyzed. The PH value of umbilical artery blood gas analysis in the study group was higher than that of the control group, but the difference was not statistically significant (P > .05). In the study group, cases with pH value < 7.0 accounted for 0%, whereas the cases with pH < 7.0 accounted for 66.67% in the control group, and the difference between the 2 groups was statistically significant (P < .05). Compared with the control group, the arterial oxygen partial pressure (PO2), the absolute value of (PCO2), lactic acid (lac) and alkali were not significantly different from those of the control group (P > .05), while the total hemoglobin (tHb) and hematocrit (Hct) were significantly lower than the control group (P < .0001). In the study group, tHb in the umbilical cord blood of 2 newborns with FMH death was significantly lower than 40 g/L. FMH should be highly suspected when there is an expression of severe asphyxia in neonates, indicated by significantly lower tHb levels in umbilical cord blood. It is helpful to improve the neonatal outcome by FMH neonatal resuscitation as soon as possible.

RESUMO

BACKGROUND: Even though effective neonatal resuscitation prevents the consequences of neonatal death related to birth asphyxia, a significant portion of healthcare personnel lacked understanding or performed it inconsistently. It is critical to have a comprehensive study that demonstrates the overall level of knowledge of healthcare providers regarding neonatal resuscitation in Eastern Africa. METHODS: Articles were searched from Science Direct, JBI databases, Web of Sciences, PubMed, and Google Scholar. The primary outcome was the level of knowledge of health care providers regarding neonatal resuscitation. Data were analyzed using Stata version 18 statistical software. The overall estimates with a 95% confidence interval were estimated using a random effect model. RESULTS: In this meta-analysis study, 7916 healthcare providers were included. The overall level of knowledge on neonatal resuscitation among healthcare providers in Eastern Africa was 59% [95% CI: 48-70]. Trained health care providers (OR = 3.63, 95% CI: 2.26, 5.00), and work experience of 5 years and above (OR = 2.08, 95% CI: 1.00, 3.16) were determinants of the level of knowledge. However, the level of education and availability of equipment were found to be insignificantly associated with the level of knowledge. CONCLUSIONS: The results of this meta-analysis showed that healthcare professionals in Eastern Africa lacked sufficient knowledge about neonatal resuscitation. Having 5 years of work experience and training in neonatal resuscitation was found to be strongly associated with knowledge level. Thus, continuing education, training courses, and frequent updates on neonatal resuscitation protocols are required for healthcare professionals.


Main findings The overall level of knowledge on neonatal resuscitation among healthcare providers in Eastern Africa was 59% [95% CI: 48­70].Added knowledge This study provides cumulative evidence on the level of knowledge of healthcare providers regarding neonatal resuscitation, and there are regional disparities and inconsistent explanations of risk factors.Global health impact for policy and action There is insufficient knowledge among healthcare providers on neonatal resuscitation in Eastern Africa, which can contribute to higher rates of neonatal mortality, highlighting the urgent need for targeted policy interventions.

RESUMO

BACKGROUND: Prolonged perinatal asphyxia (PA) may cause hypoxic-ischemic damage to the brain. The aim of this study was to investigate the brain diffusion changes of patients with PA and examine the relationship with brain damage. METHODS: This retrospective study included 55 patients diagnosed with PA, separated into mild and severe PA groups. For the evaluation of brain damage in all the study neonates, brain and diffusion MRI scans were performed using a 3T device. The scans were taken between 5 and 10 days postnatal, after completion of hypothermia treatment, in accordance with the standard clinical protocol of our institution. Apparent diffusion coefficient (ADC) values of the lentiform nucleus, thalamus, frontal white matter, and posterior limbs of the internal capsule were measured. Minitab package programs and SPSS version 20.0 software were used for statistical analysis and graphic drawing. Spearman's rank correlation analysis was used. RESULTS: The bilateral lentiform nucleus, thalamus, frontal white matter, and posterior limbs of the internal capsule ADC values were significantly higher in the severe PA group than in the mild PA group. CONCLUSIONS: In neonates with severe perinatal asphyxia, brain damage can be evaluated on diffusion-weighted imaging (DWI) of the cerebral deep white matter and basal ganglia. DWI, imaging with conventional brain MRI comes to the fore in clinical importance in PA patients.

RESUMO

The etiology of perinatal brain injury is multifactorial, but exposure to perinatal hypoxiaischemia (HI) is a major underlying factor. This review discusses the role of exposure to infection/inflammation in the evolution of HI brain injury, changes in immune responsiveness to subsequent inflammatory challenges after HI and modulation of neural outcomes with interaction between perinatal HI and inflammatory insults. The authors critically assess the clinical and preclinical evidence for the neuroprotective efficacy of therapeutic hypothermia and other anti-inflammatory treatments for inflammation-sensitized HI injury.

RESUMO

Neurologic depression in term/near-term neonates (neonatal encephalopathy, NE) is uncommon with modern obstetric care. Asphyxial birth, with or without co-factors, accounts for a minority of NE, while maldevelopment (congenital malformations, growth aberrations, genetic, metabolic and placental abnormalities) plays an enlarging role in identifying etiologic subgroups of NE. The terms NE and hypoxic-ischemic encephalopathy (HIE) have not been employed uniformly, hampering research and clinical care. The authors propose the term NE as an early working-diagnosis, to be supplemented by a diagnosis of NE due to HIE or to other factors, as a final diagnosis once workup is complete.

RESUMO

This article summarizes the current evidence regarding inflammatory biomarkers (placental and postnatal) and provides a comprehensive understanding of their roles: (1) diagnostic accuracy to predict the severity of hypoxic-ischemia encephalopathy (HIE), (2) value in assessing treatment responses, and (3) prediction of both short- and long-term neurodevelopmental outcomes. In the early critical stages of perinatal asphyxia, inflammatory biomarkers may guide clinical decision-making. Additional research is required to increase our understanding of the optimal utility of biomarkers to predict the severity, evolution, and developmental outcomes after exposure to HIE.

RESUMO

IMPORTANCE: In neonates with birth asphyxia (BA) and hypoxic-ischemic encephalopathy, therapeutic hypothermia (TH), initiated within six hours, is the only safe and established neuroprotective measure to prevent secondary brain injury. Infants born outside of TH centers have delayed access to cooling. OBJECTIVE: To compare in-hospital mortality, occurrence of seizures, and functional status at discharge in newborns with BA depending on postnatal transfer for treatment to another hospital within 24 h of admission (transferred (TN) versus non-transferred neonates (NTN)). DESIGN: Nationwide retrospective cohort study from a comprehensive hospital dataset using codes of the International Classification of Diseases, 10th modification (ICD-10). Clinical and outcome information was retrieved from diagnostic and procedural codes. Hierarchical multilevel logistic regression modeling was performed to quantify the effect of being postnatally transferred on target outcomes. SETTING: All discharges from German hospitals from 2016 to 2021. PARTICIPANTS: Full term neonates with birth asphyxia (ICD-10 code: P21) admitted to a pediatric department on their first day of life. EXPOSURES: Postnatal transfer to a pediatric department within 24 h of admission to an external hospital. MAIN OUTCOMES: In-hospital death; secondary outcomes: seizures and pediatric complex chronic conditions category (PCCC) ≥ 2. RESULTS: Of 11,703,800 pediatric cases, 25,914 fulfilled the inclusion criteria. TNs had higher proportions of organ dysfunction, TH, organ replacement therapies, and neurological sequelae in spite of slightly lower proportions of maternal risk factors. In TNs, the adjusted odds ratios (OR) for death, seizures, and PCCC ≥ 2 were 4.08 ((95% confidence interval 3.41-4.89), 2.99 (2.65-3.38), and 1.76 (1.52-2.05), respectively. A subgroup analysis among infants receiving TH (n = 3,283) found less pronounced adjusted ORs for death (1.67 (1.29-2.17)) and seizures (1.26 (1.07-1.48)) and inverse effects for PCCC ≥ 2 (0.81 (0.64-1.02)) in TNs. CONCLUSION AND RELEVANCE: This comprehensive nationwide study found increased odds for adverse outcomes in neonates with BA who were transferred to another facility within 24 h of hospital admission. Closely linking obstetrical units to a pediatric department and balancing geographical coverage of different levels of care facilities might help to minimize risks for postnatal emergency transfer and optimize perinatal care.

RESUMO

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%, P < 0.001) and clinicians (80.5%, P = 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.

RESUMO

Introduction: to help reduce neonatal mortality in Burkina Faso, we identified the prognostic factors for neonatal mortality at the Sourô Sanou University Hospital. Methods: we conducted a cross-sectional and analytical study in the neonatal department from July 25, 2019 to June 25, 2020. Patients' medical records, consultation and hospital records were reviewed. Prognostic factors for neonatal mortality were identified using a Cox model. Results: data from 1128 newborn babies were analysed. Neonatal mortality was 29.8%. Most of these deaths (89%) occurred in the early neonatal period. The mean weight of newborns at the admission was 2,285.8 ± 878.7 and 43.6%. They were at a healthy weight. Four out of five newborns had been hospitalized for infection or prematurity. The place of delivery (HR weight <1000g = 5.45[3.81 -7.79]) and the principal diagnosis (HR asphyxiation= 1.64[1.30-2.08]) were prognostic factors for neonatal mortality. Conclusion: improving technical facilities for the etiological investigation of infections and an efficient management of low-weight newborns suffering from respiratory distress would considerably reduce in-hospital neonatal mortality in Bobo-Dioulasso.

RESUMO

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 fœtus 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 fœtus 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.

RESUMO

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.

RESUMO

AIM: Swedish guidelines for therapeutic hypothermia (TH) after perinatal asphyxia were established in 2007, following several randomised studies that demonstrated improved outcomes. We assessed the implementation of hypothermia treatment in a mid-Swedish region with a sizeable proportion of outborn infants. METHOD: A population-based TH cohort from 2007 to 2015 was scrutinised for adherence to national guidelines, interhospital transport, including the use of a cooling mattress made of phase change material for thermal management, and outcomes. RESULTS: Of 136 admitted infants, 99 (73 %) were born outside the hospital. Ninety-eight percent fulfilled the criteria for postnatal depression/acidosis, and all patients had moderate-to-severe encephalopathy. Treatment was initiated within 6 h in 85 % of patients; amplitude-integrated electroencephalography/electroencephalography was recorded in 98 %, cranial ultrasound in 78 %, brain magnetic resonance imaging in 79 %, hearing tests in all, and follow-up was performed in 93 %. Although target body temperature was attained later (p < 0.01) in outborn than in inborn infants, at a mean (standard deviations) age of 6.2 (3.2) h vs 4.4 (2.6) h, 40 % of those transported using the cooling mattress were already within the therapeutic temperature range on arrival, and few were excessively cooled. The mortality rate was 23 %, and 38 % of the survivors had neurodevelopmental impairment at a median of 2.5 years. CONCLUSION: The regionalisation of TH, including interhospital transport, was feasible and resulted in outcomes comparable to those of randomised controlled studies.

RESUMO

BACKGROUND: Neonatal asphyxia is a leading cause of early neonatal mortality, accounting for approximately 900,000 deaths each year. Assessing survival rates, recovery time and predictors of mortality among asphyxiated neonates can help policymakers design, implement, and evaluate programs to achieve the sustainable development goal of reducing neonatal mortality to 12/1,000 live births by 2030. The current study sought to ascertain the survival status, recovery time, and predictors of neonatal asphyxia. METHODS: A retrospective follow-up study conducted in Debre Berhan Comprehensive Specialized Hospital, which carried out from May 20th to June 20th, 2023 using records of asphyxiated babies in NICUs from January 1st, 2020 to December 31st, 2022, involving a sample size of 330. Pre-structured questionnaires created in Google Form were used to collect data, and STATA Version 14.0 was utilized for data entry and analysis, respectively. The Kaplan-Meier survival curve, log rank test, and median time were calculated. A multivariable Cox proportional hazards regression model was fitted in order to determine the predictors of time to recovery. Variables were statistically significant if their p-value was less than 0.05. RESULTS: Three hundred thirty admitted asphyxiated neonates were followed a total of 2706 neonate -days with a minimum of 1 day to 18 days. The overall incidence density rate of survival was 9.9 per 100 neonates' days of observation (95% CI: 8.85-11.24) with a median recovery time of 9 days (95% CI: 0.82-0.93). Prolonged labor (Adjusted hazard ratio (AHR: 0.42,95%CI:0.21-0.81), normal birth weight (AHR:2.21,95% CI: 1.30-3.70),non-altered consciousness (AHR:2.52,CI:1.50-4.24),non-depressed moro reflex of the newborn (AHR:2.40,95%CI: 1.03-5.61), stage I HIE (AHR: 5.11,95% CI: 1.98-13.19),and direct oxygen administration via the nose (AHR: 4.18,95% CI: 2.21-7.89) were found to be independent predictors of time to recovery of asphyxiated neonates.. CONCLUSION: In the current findings, the recovery time was prolonged compared to other findings. This implies early diagnosis, strict monitoring and provision of appropriate measures timely is necessary before the babies complicated into the highest stage of hypoxic -ischemic encephalopathy(HIE) and managing complications are the recommended to hasten recovery time and increase the survival of neonates.

RESUMO

OBJECTIVES: Perinatal asphyxia is the main risk factor for mortality and morbidity in neonates and neurological disorders in survived infants. We compared the neonatal and maternal 25 (OH) vitamin D levels in neonates with/without asphyxia. MATERIALS AND METHODS: This cross-sectional research was done on 229 neonates (including 158 neonates [69%] without asphyxia [control group] and 71 neonates [31%] with asphyxia [case group]) from 2020 to 2023 using the available sampling method. 25 (OH) Vit D levels in mothers and neonates were assessed and compared in the 2 groups. The data collection instrument was a researcher-made checklist, containing the maternal and neonatal characteristics and laboratory evaluations. Data were analyzed by SPSS 23 using the t-test. RESULTS: The mean maternal 25 (OH) Vit D levels in the case and control groups were 16.34±11.87 and 22.80±12.67 ng/mL, respectively. The mean neonatal 25 (OH) Vit D levels in the case and control groups were respectively 12.13±8.62 and 19.55±11.62 ng/mL (P = 0.002). The case group showed severer maternal and neonatal 25 (OH) Vit D deficiency (P = 0.000) compared to the control group. CONCLUSIONS: Neonatal and maternal 25 (OH) Vit D deficiency can increase the risk of perinatal asphyxia. Therefore, administration of 25 (OH) Vit D supplements to pregnant mothers may reduce the incidence of asphyxia.

RESUMO

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. TRIAL REGISTRATION NUMBER: ChiCTR2300077368.

RESUMO

BACKGROUND: The rapid and accurate assessment of neonatal asphyxia is critical to preventing potentially fatal outcomes. Therefore, nursing students must acquire the skills to assess newborn conditions immediately after birth and implement appropriate interventions. Virtual reality (VR) simulation education has emerged as a promising tool for nursing education, offering repetitive and customizable clinical training while ensuring patient safety and overcoming spatiotemporal limitations. AIM: This study investigated the effects of a contactless hand-tracking-based immersive VR neonatal Apgar scoring program, adapted from experiential learning theory. DESIGN: A non-randomized controlled trial with a pre-post-test, quasi-experimental design was conducted. SETTINGS: The study was conducted at two nursing schools from July to October 2023. PARTICIPANTS: Participants comprised nursing students holding bachelor's degrees in nursing, with three or four years of experience and successful completion of a neonatal nursing theory course. Additionally, individuals with at least six months of experience working in a neonatal ward or delivery room before enrolling in nursing school were eligible. METHODS: The participants were divided into three groups: the VR group (n = 27) received contactless hand-tracking-based immersive VR neonatal Apgar scoring training; the simulation group (n = 28) received face-to-face Apgar scoring simulation training; and the control group (n = 26) received instruction on the Apgar scoring criteria. Changes in scores among the VR, simulation, and control groups were statistically compared using ANOVA with SPSS-WIN 27.0. RESULTS: The VR group exhibited significant improvements in knowledge, learning satisfaction, self-confidence, immersion, and motivation compared to the simulation and control groups. Moreover, satisfaction was significantly higher in the VR group than in the simulation group. CONCLUSIONS: The hand-tracking-based immersive VR neonatal Apgar scoring program represents an innovative and effective educational tool, prioritizing the privacy and rights of mothers and infants. It can potentially replace traditional delivery-room clinical training, which is observation-based and limited.

RESUMO

Perinatal asphyxia (PA) poses a significant threat to multiple organs, particularly the kidneys. Diagnosing PA-associated kidney injury remains challenging, and treatment options are inadequate. Furthermore, there is a lack of long-term follow-up data regarding the renal implications of PA. In this study, 7-day-old male Wistar rats were exposed to PA using a gas mixture (4% O2; 20% CO2 in N2 for 15 min) to investigate molecular pathways linked to renal tubular damage, hypoxia, angiogenesis, heat shock response, inflammation, and fibrosis in the kidney. In a second experiment, adult rats with a history of PA were subjected to moderate renal ischemia-reperfusion (IR) injury to test the hypothesis that PA exacerbates renal susceptibility. Our results revealed an increased gene expression of renal injury markers (kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin), hypoxic and heat shock factors (hypoxia-inducible factor-1α, heat shock factor-1, and heat shock protein-27), proinflammatory cytokines (interleukin-1ß, interleukin-6, tumor necrosis factor-α, and monocyte chemoattractant protein-1), and fibrotic markers (transforming growth factor-ß, connective tissue growth factor, and fibronectin) promptly after PA. Moreover, a machine learning model was identified through random forest analysis, demonstrating an impressive classification accuracy (95.5%) for PA. Post-PA rats showed exacerbated functional decline and tubular injury and more intense hypoxic, heat shock, proinflammatory, and profibrotic response after renal IR injury compared with controls. In conclusion, PA leads to subclinical kidney injury, which may increase the susceptibility to subsequent renal damage later in life. In addition, the parameters identified through random forest analysis provide a robust foundation for future biomarker research in the context of PA.NEW & NOTEWORTHY This article demonstrates that perinatal asphyxia leads to subclinical kidney injury that permanently increases renal susceptibility to subsequent ischemic injury. We identified major molecular pathways involved in perinatal asphyxia-induced renal complications, highlighting potential targets of therapeutic approaches. In addition, random forest analysis revealed a model that classifies perinatal asphyxia with 95.5% accuracy that may provide a strong foundation for further biomarker research. These findings underscore the importance of multiorgan follow-up for perinatal asphyxia-affected patients.
