Cause Of Neonatal Death Research Articles

MiR-203 modulates pregnant myometrium contractility via transient receptor potential vanilloid 4 channel expression.

Preterm labor is the leading cause of neonatal death and major morbidity but remains a poorly understood process with no effective tocolytic therapies. Recent work has identified the transient receptor potential vanilloid 4 (TRPV4) channel, a membrane calcium channel upregulated in uterine smooth muscle through gestation, as integral in the transition from quiescence to contraction in the gravid uterus. The present study builds upon these findings and investigates regulation of the TRPV4 channel during pregnancy in the murine and human uterus by micro-RNA 203 (miR-203). We find a progressive decrease in miR-203 expression during gestation, accompanied by a reciprocal increase in TRPV4 mRNA and protein expression. In human uterine smooth muscle cells (UtSMC), miR-203 overexpression reduces, and si-RNA-mediated silencing increases, TRPV4 expression. Studies using murine UtSMC demonstrate that miR-203 expression modulates TRPV4-mediated cytosolic calcium entry and contractility. Consistent with these findings, the response to pharmacologic TRVP4 agonists is increased in myometrial tissue from miRNA203 -/- mice compared to control mice. Moreover, we demonstrate that miR-203 binds specifically on the promoter region of TRPV4 to decrease expression. In murine inflammatory models of preterm labor, miR-203 overexpression prolongs pregnancy. Estradiol (E2) decreases miR-203 and increases TRPV4 expression, providing a potential physiologic link for the unique reciprocal relationship in UtSMC. Taken together, these findings provide evidence that miR-203 modulates uterine contractility during pregnancy via negative regulation of TRPV4. These findings support the hypothesis that targeting miR-203 holds the promise of an entirely novel approach to prevent prematurity and treat preterm labor.

Predicting the effect of nosocomial infection prevention on neonatal mortality and hospital stay in Ethiopia: a prospective longitudinal study

BackgroundNeonatal Nosocomial infections (NNIs) are a significant cause of morbidity and mortality for neonates in an intensive care unit. Neonatal causes of death in healthcare facilities are attributed to different factors. We aimed to investigate factors associated with NNIs, estimate the burden of NNIs, and assess how the prediction effects help to save medical mortality and length of hospital stay.MethodA prospective longitudinal study was conducted and data were collected from January 2022 to June 2022 from Jimma University Medical Center (JUMC). The data were gathered in a variety of ways, including an in-person interview with the patient’s caregiver, direct observations of neonatal patients, and a review of the study participants’ charts. This study includes patients aged 3 to 28 days who were admitted to the JUMC neonatal ward and stayed for at least 48 h. Multi-state model formulation and multivariate logistic regression were used for data analysis.ResultsA total of 545 neonates were included out of 688, and 30% (n = 164) of them acquired nosocomial infections (NIs); 98 (33%) of infected patients were born prematurely; and 71 (31.4%) were underweight at birth. NIs were higher in neonates with long hospital stay (AOR: 1.16, 95%CI: 1.13–1.20), use of urinary catheters (AOR: 3.09, 95%CI: 1.55–6.15), and undergoing surgical procedures (AOR: 2.42, 95%CI: 1.13–5.17). Patients who developed NIs had a higher risk of death (HR: 2, 95% CI: 1.31, 3.04). The burden of neonatal NIs was determined to have a risk of 0.3, a mortality rate of 9.6%, and an average duration of hospital stay of 14.6 days. Competing risk regression suggests that neonates with NIs have a significantly higher risk of death than those who are not infected (HR: 16.42, 95% CI: 8.70-30.98, p < 0.001). Assumed prevention that decreases the NIs rate in half would result in 101 lives and 1357 patient days saved from 10,000 neonatal inpatients.ConclusionUrinary catheterization and surgical procedure increased neonatal NIs. Longer hospital stay can increase the risk of NIs and can also result from the NIs. Our finding indicated that effective prevention of NIs could help reduce neonatal deaths and their hospital stays.

Why do new-borns die? Perspectives of community members and health care providers in the Lawra municipality of the Upper West Region, Ghana

BackgroundNeonatal deaths contribute significantly to under-five mortality and serve as a crucial indicator of a country’s socioeconomic development, quality of life, and health status. These deaths occur both at home and in health facilities. Therefore, the perspectives of community members and healthcare providers are essential in defining neonatal survival.AimThis study explored the perceived causes of neonatal deaths among healthcare professionals and community members at the Lawra Municipality in the Upper West Region, Ghana.MethodThis study employed a qualitative descriptive approach. A purposive sample of 30 participants including 18 community members and 12 healthcare providers, was selected. Data were gathered using Focus Group Discussion (FGD), transcribed verbatim, coded and analysed using thematic-content analysis.ResultsThree themes were constructed to describe the factors leading to newborn deaths both at health facilities and in the community. These factors included: (1) personal factors related to newborns, mothers/families and health staff; (2) physical factors related to hospital facilities and equipment; and (3) logistical factors related to transport, referral and presentation delays.ConclusionThe study identified differences in perspectives between healthcare providers and community members, which can affect interventions in neonatal care. Health authorities are encouraged to develop a shared vision to engage communities by addressing geographic-specific factors causing neonatal deaths. This approach can help in understanding how collective actions can contribute to reducing neonatal deaths.

Evaluating the accuracy of International Classification of Disease Perinatal Mortality (ICD-PM) codes assigned on death certificates before and after expert panel review: a mixed methods observational study

IntroductionThe present study was conducted with the aim of evaluating the accuracy of International Classification of Disease Perinatal Mortality (ICD-PM) codes assigned on death certificates before and after an expert panel review.MethodThe present study was a mixed methods observational study conducted at Umm al-Benin Hospital, the sole specialized obstetrics and gynecology center affiliated with Mashhad University of Medical Sciences. The study comprised three distinct stages: (1) Collecting primary ICD-PM codes assigned to perinatal death certificates, along with other relevant information, from October 2021 to March 2022; (2) Examining the circumstances of each perinatal death case and re-identifying the causes of death through a consensus process involving a panel of experts comprising pediatricians, obstetrics and gynecology specialists, and nursing and midwifery experts; presenting the new ICD-PM code; (3) Comparing the ICD-PM codes assigned to perinatal death certificates before and after the expert panel’s evaluation.ResultDuring the study period, a total of seven specialized panels were conducted to examine perinatal deaths. Out of the 71 cases, 41 were carefully reviewed by experts. These cases included 32 stillbirths and nine neonatal deaths. The examination process followed specific inclusion and exclusion criteria. The findings revealed that there were no significant changes in the causes of neonatal deaths. However, it was notable that 80% of the previously unknown causes of stillbirths were successfully identified. Notably, the occurrence of stillbirths increased by 78% due to maternal causes and conditions.ConclusionConvening panels of experts to discuss the causes of perinatal deaths can effectively reduce the percentage of unknown causes, as classified by ICD-PM. This approach also guarantees the availability of essential data for implementing effective interventions to decrease preventable perinatal deaths.

Significance of Modified Hodge Test in Carbapenemase Detection: A Brief Insight

Neonatal sepsis is one of the leading causes of neonatal deaths. A. baumannii-calcoaceticus is the most notorious bacterial agent. Carbapenems are the most important antibiotics and modified Hodge Test is considered as important phenotypic method for observing Carbapenemase production. Objective: To evaluate the efficacy rate of Modified Hodge Test, for detection of Carbapenem resistance. Methods: A cross sectional study was conducted at department of pathology, Nishtar Medical University, Multan from August 2023 to September 2023. The blood samples of suspected cases of sepsis were collected and after isolation of Acinetobacter baumannii sensitivity of multiple antibiotics were checked by disc diffusion method. Carbapenem resistance was re-evaluated by Modified Hodge Test using Meropenem disc (10 µg). All data were entered and analyzed by SPSS version 23.0. Results: Total samples of neonatal sepsis were 182. 83 (45.6%) were culture positive for bacterial growth. Among the positive samples 26 (31.3%) were isolated as Acinetobacter baumannii. Kirby-Bauer disc diffusion method was used to check sensitivity of multiple antibiotics including Carbapenems. Out of 26 Acinetobacter isolated samples, 16 were found to be Carbapenem resistant by this method. Modified Hodge test was used to re-confirm Carbapenem resistance. Out of 16 Meropenem resistant cases this phenotypic test only detected 5 cases (31.25%). Conclusions: Staphylococcus aureus followed by Acinetobacter baumannii were isolated predominantly and Carbapenem resistance has markedly increased. In contrast to a study conducted in 2010 in Pakistan on MHT effectiveness where effectiveness of MHT for Carbapenemase detection was satisfactory, our results reveled that some other techniques should be introduced for Carbapenemase detection as Modified Hodge test did not give satisfactory results

Early onset neonatal sepsis and its associatited factors: a cross sectional study

BackgroundSepsis is the 3rd leading cause of neonatal mortality in Ethiopia contributing to 16% of neonatal death. In a hospital study, neonatal sepsis was the leading diagnosis at admission and the second leading cause of neonatal death at the neonatal intensive care unit. Among other factors repeated vaginal examination during labor is known to contribute to sepsis in low-income settings. However, there is limited evidence in the Ethiopian setting.ObjectiveThe objective of this study was to examine the association between early-onset neonatal sepsis and repeated vaginal examinations.MethodsThe study was conducted at Gandhi Memorial Hospital, a public maternity and newborn care hospital. We followed 672 mother-newborn pairs by phone until 7 days of age to detect clinical sepsis. Data were analyzed using SPSS version 20 software. Adjusted odds ratio risk (AOR) with a corresponding 95% confidence interval (CI) was used to show the strength of associations and variables with p-value < 0.05 were considered to be statistically significant.ResultsThe incidence of early-onset neonatal sepsis was found to be 20.83% (95% CI 17.60, 24.00). Having a frequent vaginal examination (four or more times) during labor and delivery, prolonged rupture of membranes, induced labor and gestational age < 37 weeks were strongly associated with the development of early-onset neonatal sepsis, (AOR 2. 69;95 CI: 1.08, 6.70) AOR 5.12(95% CI 1.31, 20.00), AOR of 5.24 (95% CI 1.72, AOR4.34 (95% CI 1.20, 15.68), 16.00), respectively.ConclusionFrequent digital vaginal examination prolonged rupture of membranes, induced labor and gestational age < 37 weeks significantly increases the risk of early onset neonatal sepsis. We also recommend further study using neonatal blood culture to better diagnose early onset neonatal sepsis objectively.

Mitochondrial dynamics and sex-specific responses in the developing rat hippocampus: Effect of perinatal asphyxia and mesenchymal stem cell Secretome treatment

AimsPerinatal asphyxia is one of the major causes of neonatal death at birth. Survivors can progress but often suffer from long-term sequelae. We aim to determine the effects of perinatal asphyxia on mitochondrial dynamics and whether mesenchymal stem cell secretome (MSC-S) treatment can alleviate the deleterious effects. Materials and methodsAnimals were subjected to 21 min of asphyxia at the time of delivery. MSC-S or vehicle was intranasally administered 2 h post-delivery. Mitochondrial mass (D-loop, qPCR), mitochondrial dynamics proteins (Drp1, Fis1 and OPA1, Western blot), mitochondrial dynamics (TOMM20, Immunofluorescence), as well as mitochondrial membrane potential (ΔΨm) (Safranin O) were evaluated at P1 and P7 in the hippocampus. Key findingsPerinatal asphyxia increased levels of mitochondrial dynamics proteins Drp1 and S-OPA1 at P1 and Fis1 at P7. Mitochondrial density and mass were decreased at P1. Perinatal asphyxia induced sex-specific differences, with increased L-OPA1 in females at P7 and increased mitochondria circularity. In males, asphyxia-exposed animals exhibited a reduced ΔΨm at P7. MSC-S treatment normalised levels of mitochondrial dynamics proteins involved in fission. SignificanceThis study provides novel insights into the effects of perinatal asphyxia on mitochondrial dynamics in the developing brain and on the therapeutic opportunities provided by mesenchymal stem cell secretome treatment. It also highlights on the relevance of considering sex as a biological variable in perinatal brain injury and therapy development. These findings contribute to the development of targeted, personalised therapies for infants affected by perinatal asphyxia.

Elevated cerebral perfusion in neonatal encephalopathy is associated with neurodevelopmental impairments.

Neonatal encephalopathy (NE) represents a primary cause of neonatal death and neurodevelopmental impairments. In newborns with NE, cerebral hyperperfusion is related to an increased risk of severe adverse outcomes, but less is known about the link between perfusion and mild to moderate developmental impairments or developmental delay. Using arterial spin labelling perfusion MRI, we investigated the link between perfusion in 36 newborns with NE and developmental outcome at 2 years. 53% of the infants demonstrated a normal outcome at 24 months, while two had cerebral palsy with impairments in cognitive, motor, and language domains, and three infants died. The remaining infants showed mild or moderate delays in development in one or two domains. Hyperperfusion across the whole brain was associated with more adverse outcome, including an increased risk of death or severe disability such as cerebral palsy. Among the surviving infants, higher perfusion in the bilateral basal ganglia, thalamus, hippocampus and cerebellum during the neonatal period was related to a poorer cognitive outcome at 2 years. Hyperperfusion in infants with NE was associated with a more adverse outcome and lower cognitive outcome scores. In addition to severe adverse outcomes, altered perfusion is also related to mild to moderate impairment following HIE. Neonates with neonatal encephalopathy (NE) show increased cerebral perfusion globally, which is linked to a more adverse outcome. Higher perfusion in the bilateral basal ganglia, thalamus, hippocampus and cerebellum during the neonatal period was related to a poorer cognitive outcome at 2 years. In addition to severe adverse outcomes altered perfusion is related to mild to moderate impairment following NE. To improve neurodevelopmental outcomes, it is important to improve our understanding of the factors influencing cerebral perfusion in infants with NE.

Neonatal screening for critical congenital heart diseases in Peru: an urgent call

Congenital heart diseases are the most common congenital malformations worldwide and represent one of the leading causes of neonatal death, in addition to the significant use of human and financial resources by health systems. The purpose of this document is to support the implementation of neonatal screening for critical congenital heart diseases using pulse oximetry according to the different geographical altitudes of Peru. This technology is widely used worldwide and has high sensitivity, specificity, and cost-effectiveness. At many latitudes, it has led to better survival in this group of patients and in the neonatal population in general since its use in the early detection of sepsis, pneumonia, and other conditions that affect the oxygenation of the newborn. Neonatal screening for critical congenital heart disease is applicable at all levels of healthcare at a national level, and its implementation must be a priority to improve neonatal health.

Identification of key metabolism-related genes and pathways in spontaneous preterm birth: combining bioinformatic analysis and machine learning.

Spontaneous preterm birth (sPTB) is a global disease that is a leading cause of death in neonates and children younger than 5 years of age. However, the etiology of sPTB remains poorly understood. Recent evidence has shown a strong association between metabolic disorders and sPTB. To determine the metabolic alterations in sPTB patients, we used various bioinformatics methods to analyze the abnormal changes in metabolic pathways in the preterm placenta via existing datasets. In this study, we integrated two datasets (GSE203507 and GSE174415) from the NCBI GEO database for the following analysis. We utilized the "Deseq2" R package and WGCNA for differentially expressed genes (DEGs) analysis; the identified DEGs were subsequently compared with metabolism-related genes. To identify the altered metabolism-related pathways and hub genes in sPTB patients, we performed multiple functional enrichment analysis and applied three machine learning algorithms, LASSO, SVM-RFE, and RF, with the hub genes that were verified by immunohistochemistry. Additionally, we conducted single-sample gene set enrichment analysis to assess immune infiltration in the placenta. We identified 228 sPTB-related DEGs that were enriched in pathways such as arachidonic acid and glutathione metabolism. A total of 3 metabolism-related hub genes, namely, ANPEP, CKMT1B, and PLA2G4A, were identified and validated in external datasets and experiments. A nomogram model was developed and evaluated with 3 hub genes; the model could reliably distinguish sPTB patients and term labor patients with an area under the curve (AUC) > 0.75 for both the training and validation sets. Immune infiltration analysis revealed immune dysregulation in sPTB patients. Three potential hub genes that influence the occurrence of sPTB through shadow participation in placental metabolism were identified; these results provide a new perspective for the development and targeting of treatments for sPTB.

Effects of pulmonary surfactant combined with noninvasive positive pressure ventilation in neonates with respiratory distress syndrome.

Neonatal respiratory distress syndrome (NRDS) is one of the most common diseases in neonatal intensive care units, with an incidence rate of about 7% among infants. Additionally, it is a leading cause of neonatal death in hospitals in China. The main mechanism of the disease is hypoxemia and hypercapnia caused by lack of surfactant. To explore the effect of pulmonary surfactant (PS) combined with noninvasive positive pressure ventilation on keratin-14 (KRT-14) and endothelin-1 (ET-1) levels in peripheral blood and the effectiveness in treating NRDS. Altogether 137 neonates with respiratory distress syndrome treated in our hospital from April 2019 to July 2021 were included. Of these, 64 control cases were treated with noninvasive positive pressure ventilation and 73 observation cases were treated with PS combined with noninvasive positive pressure ventilation. The expression of KRT-14 and ET-1 in the two groups was compared. The deaths, complications, and PaO2, PaCO2, and PaO2/FiO2 blood gas indexes in the two groups were compared. Receiver operating characteristic curve (ROC) analysis was used to determine the diagnostic value of KRT-14 and ET-1 in the treatment of NRDS. The observation group had a significantly higher effectiveness rate than the control group. There was no significant difference between the two groups in terms of neonatal mortality and adverse reactions, such as bronchial dysplasia, cyanosis, and shortness of breath. After treatment, the levels of PaO2 and PaO2/FiO2 in both groups were significantly higher than before treatment, while the level of PaCO2 was significantly lower. After treatment, the observation group had significantly higher levels of PaO2 and PaO2/FiO2 than the control group, while PaCO2 was notably lower in the observation group. After treatment, the KRT-14 and ET-1 levels in both groups were significantly decreased compared with the pre-treatment levels. The observation group had a reduction of KRT-14 and ET-1 levels than the control group. ROC curve analysis showed that the area under the curve (AUC) of KRT-14 was 0.791, and the AUC of ET-1 was 0.816. Combining PS with noninvasive positive pressure ventilation significantly improved the effectiveness of NRDS therapy. KRT-14 and ET-1 levels may have potential as therapeutic and diagnostic indicators.

Analysis of the causes of neonatal death and genetic variations in congenital anomalies: a multi-center study.

Neonatal deaths often result from preventable conditions that can be addressed with appropriate interventions. This study aims to analyze the distribution of the causes of neonatal death and explore genetic variations that lead to congenital anomalies in Northwest China. This multi-center observational study was conducted across six medical centers in Shaanxi province, Northwest China. Clinical data were retrospectively collected from neonates admitted between 2016 and 2020. Kaplan-Meier analysis was utilized to estimate survival rates, while high-throughput sequencing platforms were employed to detect mutations causing congenital anomalies. Among 73,967 neonates requiring hospital care, 424 neonatal deaths were recorded, leading to a neonatal mortality rate of 0.57%. The primary causes of death included neonatal respiratory distress syndrome (23.8%), birth asphyxia (19.8%), neonatal septicemia (19.3%), and congenital anomalies (13.6%). The leading causes of neonatal deaths due to congenital anomalies were congenital heart defects (38.6%), bronchopulmonary dysplasia (14.0%), and inherited metabolic disorders (10.5%). Genetic analysis identified 83 pathogenic or likely pathogenic variants in 23 genes among the neonates with congenital anomalies, including four novel mutations (c.4198+1G>T, c.1075delG, c.610-1G>A, c.7769C>T) in the ABCC8, CDKL5, PLA2G6, and NIPBL genes. Congenital anomalies represent a significant and preventable cause of neonatal deaths in Northwest China. Early detection of congenital anomalies through genetic testing and comprehensive prenatal care are crucial for reducing neonatal mortality rates and improving pregnancy outcomes.

Current status and controversies in the treatment of neonatal hypoxic-ischemic encephalopathy: A review.

Neonatal hypoxic-ischemic encephalopathy is a type of traumatic brain injury caused by insufficient cerebral perfusion and oxygen supply in the perinatal neonate, which can be accompanied by different types of long-term neurodevelopmental sequelae, such as cerebral palsy, learning disabilities, mental retardation and epilepsy It is one of the main causes of neonatal death and disability, and it has caused a great burden on families and society. Therefore, this article mainly reviews the latest developments in mild hypothermia therapy and related drugs for neonatal hypoxic-ischemic encephalopathy.

Git2 deficiency promotes MDSCs recruitment in intestine via NF-κB-CXCL1/CXCL12 pathway and ameliorates necrotizing enterocolitis

Necrotizing enterocolitis (NEC) is a severe gastrointestinal disease in preterm infants and the most common cause of neonatal death, whereas the molecular mechanism of intestinal injury remains unclear accompanied by deficiency of effective therapeutic approaches. GIT2 (G-protein-coupled receptor kinase interacting proteins 2) can affect innate and adaptive immunity and has been involved in multiple inflammatory disorders. In this study, we investigated whether GIT2 participates in the pathogenesis of NEC. Here we found that intestinal Git2 gene expression was significantly increased in NEC patients and NEC mice, which positively correlated with the tissue damage severity, and Git2 deficiency could potently protect against NEC development in mice. Mechanistically, Git2 gene knockout dramatically increased the recruitment of MDSCs in the intestine, and in vivo depletion of MDSCs almost completely abrogated the protective effect of Git2 deficiency on NEC. Moreover, Git2 deficiency induced MDSCs intestinal accumulation mainly relied on CXCL1/CXCL12 signaling, as evidenced by the significant increment of CXCL1 and CXCL12 levels in intestinal epithelium of Git2-/- mice and dramatically decrease of MDSCs accumulation in intestine as well as increase of NEC severity upon treatment of CXCL1/CXCL12 pathway inhibitors. In addition, Git2 deficiency induced up-regulation of CXCL1 and CXCL12 is at least partially mediated through activating NF-κB signaling. Thus, our findings suggest that GIT2 is involved in the pathogenesis of NEC, and targeting GIT2 may be a potential preventive and therapeutic approach for NEC.

In-Person Versus Online Training in Simulations of Helping Babies Breathe: A Randomized Controlled Trial.

Birth asphyxia is a leading cause of neonatal deaths, but simple interventions may prevent it. The Helping Babies Breathe (HBB) course has significantly reduced neonatal mortality ratesin lower and middle-income countries (LMICs) by training healthcare providers (i.e. midwives and nurses) on the essential skills of bag-and-mask ventilation and postnatal care. Although several studies have supported the efficacy of virtual learning in other medical education programs, there is still a lack of knowledge regarding a virtual approach to HBB. This study aims to compare the effectiveness of online versus in-person learning of the HBB course among medical and nursing students. The study is a two-arm parallel randomized non-inferiority controlled trial, that includes medical and nursing students. Participants were randomly assigned to either online or in-person debriefing during the hands-on simulations of HBB. They attended a pre-recorded lecture before being assigned to one of three instructors for the simulation lab. Participants completed a seven-point anonymous Likert-based questionnaire and a standardized Debriefing Assessment for Simulation in Healthcare Student Version (DASH-SV) Short Form. The primary outcome was the Objective Structured Clinical Exam (OSCE) grade. The trial is listed on ClinicalTrials.gov with the registration number NCT05257499. 47 participants completed the study, with similar baseline characteristics in each arm (gender, age, and class). The participants in both arms reported high levels of satisfaction and confidence, with no significant difference between the two arms. The DASH score over 7 was also similar in the online arm(6.27±0.26) compared to the in-person arm (6.55±0.13) (p=0.07). The mean OSCE scorein the online arm (45.8±5.2) was comparable to the mean OSCE score in the in-person arm (41.3±5.0) (p=0.22). Both online and in-person participants failed the OSCE. The survey responses conveyed that online simulation training is comparable to in-person simulation for the HBB course. Both online and in-person participants failed the OSCE most likely because they needed more training on HBB. This could be due to the fact that the material is too new to the students who needed more practice to pass the OSCE. Further research is needed to confirm these results and explore the long-term impact of online neonatal resuscitation training.

Retrospective evaluation of neonates with fatal congenital lung malformation: A single center 15-year forensic autopsy experience.

Congenital lung malformation (CLM) is a leading cause of infant mortality. Clinical methods for diagnosing CLM mainly rely on computed tomography, magnetic resonance imaging, ultrasonography, and Doppler. However, forensic identification of the cause of death in neonates is challenging. Unequivocal classification criteria for CLM are missing as its forensic identification is ambiguous. Therefore, we aimed to analyze neonatal death cases at our center to assist in identifying those with congenital lung malformation. This retrospective study identified and classified the causes of deaths of neonates autopsied between January 2008 and April 2023. All cases born alive and died within 28 days with a clear time of death were selected, and forensic experts reviewed their records. The manner, cause of death, and other characteristics were noted and discussed. This retrospective study reveals a steady increase in autopsy cases from 2008 to 2015, attributed to improved parental consent, heightened awareness of autopsy importance, and enhanced medical resources. However, a subsequent decline post-2015 is observed, potentially influenced by advancements in medical technology and prenatal examination protocols. The top causes of neonatal mortality include respiratory diseases, asphyxia, congenital dysplasia, and fetal distress. Congenital lung malformations, particularly bronchopulmonary malformations, constitute a significant portion of congenital anomalies. This study underscores the importance of standardized autopsies and histopathological examinations in diagnosing and understanding CLM. Future research should focus on expanding case collections and elucidating the genetic basis of CLM to improve forensic management and outcomes.

Impairment of Renal Function and Dyselectrolytemia in Perinatal Asphyxia

Background: Perinatal asphyxia is one of the major causes of neonatal death and disabilityworldwide. Asphyxiated newborns are vulnerable to develop impaired renal functions andderangement in electrolytes level.Objective: To determine the effects of perinatal asphyxia on renal functions and serumelectrolytes.Methods: This cross sectional observational study was conducted at inpatient department ofPaediatrics of Rangpur Medical College Hospital from May 2017to October 2017. After parentalpermission and clearance, total 200 eligible hospitalized term neonates fulfilling the inclusionand exclusion criteria were enrolled into the study. Estimation of serum creatinine, blood urea,serum sodium and potassium were done for every neonate after hospitalization. Data collectionand processing were done for each patient. Data were analyzed through SPSS software (version16.0). Level of significance was predetermined as p&lt;0.05.Results: Analysis revealed that out of 200 neonates 130(65%) patients were in Hypoxic IshchemicEncephalopathy stage-ll followed by 50(25%) and 20(10%) patients in stage-lll and stage-lrespectively. Of total subjects, 68(34%) neonates had raised serum creatinine (p&lt;0.001) andmajority (36 cases out of 50,18% of total) of them were in stage-lll. Blood urea wasraised(p&lt;0.001) in more than half (112 cases out of 200, 56% of total neonates) of the asphyxiatedneonates, higher level was observed in stage-ll and stage-lll. Majority of asphyxiated neonates139(69.5%) were hyponatremic which was significant in all stages of birth asphyxia (p=0.026).Hyperkalemia observed in 38(19%) asphyxiated neonates which was significant with increasedseverity of perinatal asphyxia (p=0.007).Conclusion: Renal function impairment and electrolyte abnormalities are common in asphyxiatednewborns. The degree of hyponatremia, hyperkalemia, raised serum creatinine and blood urea levelwere directly proportionate to severity of asphyxia. The early identification and time basedintervention to assess renal function and electrolyte abnormality in the early post asphyxiatedperiod will significantly reduce the morbidity and mortality.

Neonatal mortality during the war in Tigray: a cross-sectional community-based study

Neonatal mortality is among the key national and international indicators of health services. The global Sustainable Development Goal target for neonatal mortality is fewer than 12 deaths per 1000 livebirths, by 2030. Neonatal mortality estimates in the 2019 Ethiopian Demographic Health Survey found 25·7 deaths per 1000 livebirths. Subnational surveys specific to Tigray, Ethiopia, reported a neonatal mortality lifetime prevalence of 7·13 deaths. Another government report from the Tigray region estimated a neonatal mortality rate of ten deaths per 1000 livebirths in 2020. Despite the numerous interventions in Ethiopia's Tigray region to achieve the Sustainable Development Goals, the war has disrupted most health services, but the effect on neonatal mortality is unknown. Thus, this study aimed to investigate the magnitude and causes of neonatal mortality during the war in Tigray. A cross-sectional community-based study was conducted in Tigray to evaluate neonatal mortality that occurred from Nov 4, 2020, to May 30, 2022. Among the 31 districts, 121 tabias were selected using computer-generated random sampling, and 189 087 households were visited. We adopted a validated WHO 2022 verbal autopsy tool, and data were collected using an interviewer-administrated Open Data Kit. In the absence of the mother, other respondents to the verbal autopsy interview were household members aged 18 years and older who provided care during the final illness that led to death. 29 761 livebirths were recorded during the screening of 189 087 households. Verbal autopsy was administered for 1158 households with neonatal deaths. 317 neonates were stillborn, and 841 neonatal deaths were recorded with the WHO 2022 verbal autopsy tool from Nov 4, 2020, to May 30, 2022, in 31 districts. The neonatal mortality rate was 28·2 deaths per 1000 livebirths. 476 (57%) of the 841 neonatal deaths occurred at home and 296 (35%) in health facilities. A high rate of neonatal deaths was reported in rural districts (80% [673 of 841]) compared with urban districts (20% [168 of 841]), and 663 (79%) deaths occurred during the early neonatal period, in the first week of life (0-6 days). The leading causes of neonatal death were asphyxia (35% [291 of 834]), prematurity (30% [247 of 834]), and infection (12% [104 of 834]). Asphyxia (37% [246 of 663]) and infection (28% [50 of 178]) were the leading causes of death for early and late neonatal period deaths, respectively. Neonatal mortality in Tigray is high due to preventable causes. An urgent response is needed to prevent the high number of neonatal deaths associated with the depleted health resources and services resulting from the war, and to achieve the Sustainable Development Goal on neonatal mortality.

Predictors of neonatal mortality among neonates admitted to the neonatal intensive care unit at Hawassa University Comprehensive Specialized Hospital, Sidama regional state, Ethiopia

BackgroundDespite promising efforts, substantial deaths occurred during the neonatal period. According to estimates from the World Health Organization (WHO), Ethiopia is among the top 10 nations with the highest number of neonatal deaths in 2020 alone. This staggering amount makes it difficult to achieve the SDG (Sustainable Development Goals) target that calls for all nations to work hard to meet a neonatal mortality rate target of ≤ 12 deaths per 1,000 live births by 2030. We evaluated neonatal mortality and it’s contributing factors among newborns admitted to the Neonatal Intensive Care Unit (NICU) at Hawassa University Comprehensive Specialized Hospital (HUCSH).MethodsA hospital-based retrospective cross-sectional study on neonates admitted to the NICU from May 2021 to April 2022 was carried out at Hawassa University Comprehensive Specialized Hospital. From the admitted 1044 cases over the study period, 225 babies were sampled using a systematic random sampling procedure. The relationship between variables was determined using bivariate and multivariable analyses, and statistically significant relations were indicated at p-values less than 0.05.ResultsThe magnitude of neonatal death was 14.2% (95% CI: 0.099–0.195). The most common causes of neonatal death were prematurity 14 (43.8%), sepsis 9 (28.1%), Perinatal asphyxia 6 (18.8%), and congenital malformations 3 (9.4%). The overall neonatal mortality rate was 28 per 1000 neonate days. Neonates who had birth asphyxia were 7.28 times more probable (AOR = 7.28; 95% CI: 2.367, 9.02) to die. Newborns who encountered infection within the NICU were 8.17 times more likely (AOR = 8.17; 95% CI: 1.84, 36.23) to die.ConclusionThe prevalence of newborn death is excessively high. The most common causes of mortality identified were prematurity, sepsis, perinatal asphyxia and congenital anomalies. To avert these causes, we demand that antenatal care services be implemented appropriately, delivery care quality be improved, and appropriate neonatal care and treatment be made available.

Risk factors for the incident of respiratory distress syndrome in neonates at the Regional General Hospital of Buleleng District, 2020

&lt;p&gt;&lt;strong&gt;&lt;em&gt;Background&lt;/em&gt;&lt;/strong&gt;&lt;em&gt; : The main causes of death in neonates are complications of pregnancy and childbirth, such as asphyxia, sepsis and low birth weight complications. Respiratory Distress Syndrome (RDS) is a condition related to the respiratory system of neonates. The large number of RDS cases is one of the highest causes of death in neonates.&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;Objectives&lt;/em&gt;&lt;/strong&gt;&lt;em&gt;: The aim of this study is to determine the risk factors for the incidence of RDS at Buleleng District Hospital, especially in premature neonates in 2020.&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;Methods&lt;/em&gt;&lt;/strong&gt;&lt;em&gt;: This research method uses a retrospective cohort study. Where the data was taken using secondary data in the NICCU room at Buleleng Regional Hospital. The independent variables included are the characteristics of the neonate including gestational age, history of hypertension experienced by the mother during pregnancy, birth weight, history of premature rupture of membranes, history of asphyxia experienced during the birth process. The dependent variable in this study was the incidence of RDS in neonates. The sample included in this research was 64 mothers who gave birth at the Buleleng District Hospital in 2020. This research used univariate analysis to assess the frequency distribution of each variable, then continued using bivariate analysis to determine the variables that were included in the multivariate analysis. Multivariate analysis was carried out computerized using logistic regression&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;Results&lt;/em&gt;&lt;/strong&gt;&lt;em&gt;: The results of this study found that there were 2 risk factors that directly increased the incidence of RDS in neonates including premature gestational age with a value of p 0.01 (19.8, 95% CI 1.8-133.7, low birth weight ( 2.9, 95% CI 1.9-8.4). &lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;Conclusions&lt;/em&gt;&lt;/strong&gt;&lt;em&gt;: The conclusion is that there are 2 risk factors that are associated and increase the incidence of RDS in neonates, namely premature gestational age and low birth weight.&lt;/em&gt;&lt;/p&gt;
