Comparison of Clinical Diagnosis and Autopsy Findings of Early Neonatal Deaths: Diagnostic Challenges and the Value of Autopsy in Identifying Rare Pathologies.

In a non-forensic hospital setting, neonatal death within the first week of life is often related to premature birth and/or lung diseases. Without post-mortem examination, the identification of the cause of death may be challenging. Autopsy can confirm the clinical diagnosis, uncover additional information or change the diagnosis. Our study aimed to assess the correlation between the clinical diagnosis and post-mortem findings in early neonatal deaths. The retrospective study included autopsy cases with neonatal deaths within the first 7 days of life (arbitrary time interval 2006-2021). Discrepancies between clinical and histopathological findings were classified into 3 groups: (i) full agreement, (ii) additional findings discovered by autopsy, or (iii) autopsy changed the diagnosis. A cohort of 27 cases could be identified and lung pathologies were the most common finding (56%). Additional findings could be discovered in 48% of cases. Major discrepancies which changed the clinical diagnosis could be found in 11% (n = 3/27) of cases. Frequently, post-mortem examinations validate the clinical diagnosis while revealing crucial information in a few cases. In these discrepant cases, autopsy findings can provide information for genetic counselling and quality control of clinical management.

Examining priorities and investments made through the Global Financing Facility for maternal and newborn health: a sub-analysis on quality

ABSTRACT Improving quality of care could avert most of the 4.5 million maternal and neonatal deaths and stillbirths that occur each year. The Global Financing Facility (GFF) aims to catalyse the national scale-up of maternal and newborn health (MNH) interventions through focused investments. Achieving impact and value for money requires high, equitable coverage and high quality of interventions. This study examines whether the rhetoric of increasing coverage together with quality has informed investment strategies in MNH through a secondary analysis of 25 GFF documents from 11 African countries. The analysis shows that the country GFF-related documents incorporate some MNH-related quality of care components; however, there is a lack of clarity in what is meant by quality and the absence of core MNH quality of care components as identified by the World Health Organization’s MNH quality framework, especially experience of care and newborn care. Many of the Investment Cases have a more diagonal focus on MNH service delivery considering the clinical dimensions of quality, while the investments described in the Project Appraisal Documents are primarily on horizontal structural aspects of the health system strengthening environment. The GFF is at the forefront of investing in MNH globally and provides an important opportunity to explicitly link health systems investments and quality interventions within the MNH continuum of care for optimal impact.

Clinical Outcomes of Meningomyelocele Infants Without Antenatal Surgery: Mortality and Morbidity in a Tertiary ICU Setting Objective To investigate the early clinical outcomes of infants with meningomyelocele Material and methods We included infants with meningomyelocele who had undergone treatment in our tertiary neonatal intensive care unit. We included all patients with meningomyelocele between 2016-2023. We retrospectively recorded data and assessed perinatal history, morbidity, and mortality status. A p-value of

Maternity waiting home utilization and associated factors in the rural community of Dangur District, Northwestern Ethiopia: results from a community-based cross-sectional household survey

BackgroundApproximately 80% of people in Ethiopia live in rural areas, where poor access to maternity services, accounts for the majority of maternal and perinatal deaths. Maternity waiting homes are residential facilities for women who come from remote areas to stay and wait before giving birth at health facilities, particularly in hospitals and health centers. It is a new initiative and one of the strategies that increase skilled care utilization at birth. However, there is no evidence on the status of maternity waiting home utilization in the study area. Therefore, this study aimed to generate evidence on the status of maternity waiting home utilization and its associated factors.MethodsA community-based cross-sectional household survey was conducted from June 5–30, 2022. The sample size was calculated using the single population proportion formula, which resulted in 354 participants. The study population included mothers who gave birth within 12 months before the survey were selected by using a systematic sampling method. The data were coded, edited, cleaned, and entered into Epi Data version 3.1. The data were subsequently exported to SPSS version 25 for analysis. Descriptive, bivariable, and multivariable binary logistic regression analyses were performed. The results are presented in the text, figures, and tables. Finally, variables with a p value < 0.05 in the multivariable analysis were reported as significantly associated with the independent variables and outcome variable.ResultsThe magnitude of maternity waiting home utilization was 36.4% (95% CI = 31.4, 41.8). Being knowledgeable about the presence of maternity waiting home (AOR = 3.9; 95% CI: 1.0-15.2), being able to afford transportation (AOR = 2.4; 95% CI: 1.01–5.9), being home delivery (AOR = 0.007; 95% CI: 0.002–0.031) and being acess to transportation services (AOR = 3.0; 95% CI: 1.2–7.5) were significantly associated with maternity waiting home utilization.ConclusionThe magnitude of maternity waiting home utilization in the study area was found to be low. Access to and affordability of transportation services, being knowledgeable and being home delivery were associated factors for the use of maternity waiting homes. Therefore, increasing maternal knowledge, economically empowering women and respecting care while waiting at maternity homes are important for improving the utilization of maternity waiting homes.

Clinical and epidemiological profiles of newborns from twin pregnancies in Hassan II University Hospital of Fez, Morocco

Twin pregnancies are high-risk pregnancies, and delivery of twins poses variable difficulties due to the complexity of obstetrical mechanics and the frequency of dystocic presentations. Twin births represent a real public health issue and are responsible for a high rate of perinatal mortality. This study aims to report on newborns' epidemiological, clinical, therapeutic, and evolutionary aspects from twin pregnancies hospitalized in the Neonatal Intensive Care and Neonatology Department of the Hassan II University Hospital, Fez. A cross-sectional, retrospective, and descriptive study was conducted on newborns from twin pregnancies hospitalized in the neonatal and neonatal intensive care unit over two and a half years. Statistical analyses were performed using the JAMOVI software. Qualitative variables were expressed as frequencies and percentages, while quantitative variables were presented as means with standard deviations (SD) or medians with interquartile ranges (IQR). A total of 96 newborns from twin pregnancies were collected. The average maternal age was 29.7 years. Maternal complications during pregnancy were dominated by the threat of premature delivery (38.77%), premature rupture of membranes 5.49%), and urinary and cervicovaginal infectious complications (12.24%).89.8% of deliveries were medicalized, with vaginal delivery being the most common (69.39%).91.67% of newborns were premature, thus dominating neonatal morbidity. The average weight was 1585g +/- 425g.76.04% of newborns presented with neonatal respiratory distress, the most frequent etiology of which was hyaline membrane disease. These neonates presented other complications: neonatal jaundice (62.5%), perinatal anoxo-ischemia (6.25%), and transfusion-transfusion syndrome (6.25%). The neonatal mortality rate was 31.25%, with the leading cause being severe neonatal infection (56.67%). The prevalence of twin pregnancies is on the rise, with a high prevalence of prematurity among newborns, requiring special attention to limit complications.

Maternal mental disorders and neonatal outcomes: Danish population-based cohort study.

Previous studies have indicated associations between maternal mental disorders and adverse birth outcomes; however, these studies mainly focus on certain types of mental disorders, rather than the whole spectrum. We aimed to conduct a broad study examining all maternal mental disorder types and adverse neonatal outcomes which is needed to provide a more complete understanding of the associations. We included 1 132 757 liveborn singletons born between 1997 and 2015 in Denmark. We compared children of mothers with a past (>2 years prior to conception; n = 48 646), recent (2 years prior to conception and during pregnancy; n = 15 899) or persistent (both past and recent; n = 10 905) diagnosis of any mental disorder, with children of mothers with no mental disorder diagnosis before the index delivery (n = 1 057 307). We also considered different types of mental disorders. We calculated odds ratios and 95% CIs of low birthweight, preterm birth, small for gestational age, low Apgar score, Caesarean delivery and neonatal death. Odds ratios for children exposed to past, recent and persistent maternal mental disorders suggested an increased risk for almost all adverse neonatal outcomes. Estimates were highest for children in the 'persistent' group for all outcomes, with the exception of the association between persistent maternal mental disorders and neonatal death (odds ratio 0.96, 0.62-1.48). Our study provides evidence for increased risk of multiple adverse neonatal outcomes among children of mothers with mental disorders, highlighting the need for close monitoring and support for women with mental disorders.

Adverse perinatal outcomes associated with different classes of antiretroviral drugs in pregnant women living with HIV: a systematic review and meta-analysis.

Women living with HIV (WLHIV) are at increased risk of adverse perinatal outcomes compared to HIV-negative women, despite antiretroviral therapy (ART). There is evidence that the risk of adverse perinatal outcomes may differ according to ART regimen. We aimed to assess the risk of adverse perinatal outcomes among WLHIV receiving different classes of ART, compared to HIV-negative women. Systematic review and meta-analysis. We searched Medline, CINAHL, Global Health and EMBASE for studies published between 1 January 1980 and 14 July 2023. We included studies which assessed the risk of 11 predefined adverse perinatal outcomes among WLHIV receiving non-nucleoside reverse transcriptase inhibitor (NNRTI)-based ART, protease inhibitor (PI)-based ART or integrase strand transfer inhibitor (INSTI)-based ART, compared to HIV-negative women. The perinatal outcomes assessed were preterm birth (PTB), very PTB (VPTB), spontaneous PTB (sPTB), low birthweight (LBW), very LBW (VLBW), term LBW, preterm LBW, small for gestational age (SGA), very SGA (VSGA), stillbirth and neonatal death (NND). Random effects meta-analyses examined the risk of each adverse outcome in WLHIV receiving either NNRTI-based, PI-based or INSTI-based ART, compared with HIV-negative women. Subgroup and sensitivity analyses were conducted based on country income status, study quality, and timing of ART initiation. The protocol is registered with PROSPERO, CRD42021248987. Of 108,720 identified citations, 22 cohort studies including 191,857 women were eligible for analysis. We found that WLHIV receiving NNRTI-based ART (mainly efavirenz or nevirapine) are at increased risk of PTB (risk ratio (RR) 1.40, 95% confidence interval 1.27-1.56), VPTB (1.94, 1.25-3.01), LBW (1.63, 1.30-2.04), SGA (1.53, 1.17-1.99) and VSGA (1.48, 1.16-1.87), compared with HIV-negative women. WLHIV receiving PI-based ART (mainly lopinavir/ritonavir or unspecified) are at increased risk of PTB (1.88, 1.55-2.28), VPTB (2.06, 1.01-4.18), sPTB (16.96, 1.01-284.08), LBW (2.90, 2.41-3.50), VLBW (4.35, 2.67-7.09) and VSGA (2.37, 1.84-3.05), compared with HIV-negative women. WLHIV receiving INSTI-based ART (mainly dolutegravir) are at increased risk of PTB (1.17, 1.06-1.30) and SGA (1.20, 1.08-1.33), compared with HIV-negative women. The risks of adverse perinatal outcomes are higher among WLHIV receiving ART compared with HIV-negative women, irrespective of the class of ART drugs. This underlines the need to further optimise ART in pregnancy and improve perinatal outcomes of WLHIV.

Nulliparous Individuals with Class III Obesity: Adverse Outcomes with Labor versus Planned Cesarean Delivery.

Individuals with class III obesity (body mass index [BMI] ≥ 40 kg/m2) are at increased risk of cesarean delivery (CD) and peripartum complications. We ascertained compositive neonatal and maternal adverse outcomes among individuals with class III obesity who labored versus had planned CD. This was a retrospective cohort study from 2016 to 2021 using the National Vital Statistics System database. Nulliparous individuals with class III obesity prepregnancy were included if they had singleton, nonanomalous pregnancies and delivered at 37 to 41 weeks of gestation. Individuals were excluded if they had hypertensive disorders or diabetes. The primary outcome was a composite neonatal adverse outcome (CNAO), consisting of Apgar score less than 5 at 5 minutes, assisted ventilation > 6 hours, neonatal seizure, or neonatal death. The secondary outcome was a composite maternal adverse outcome (CMAO) that included admission to the intensive care unit, maternal transfusion, uterine rupture, or unplanned hysterectomy. A sensitivity analysis using a CMAO without transfusion was performed. A multivariable Poisson regression model was performed to calculate adjusted relative risks (aRRs) with 95% confidence intervals (CIs). Of 192,298 individuals who met inclusion criteria, 169,676 (88.2%) labored and 22,622 (11.8%) had a planned CD. Compared with neonates delivered by planned CD, the risk of CNAO was significantly lower in those who delivered after labor (aRR: 0.79, 95% CI: 0.71-0.87). There was no significant difference in the risk of CMAO between groups (aRR: 1.11, 95% CI: 0.87-1.41). However, the risk of CMAO without transfusion was lower in individuals who labored (aRR: 0.57, 95% CI: 0.40-0.83). In nulliparous individuals with class III obesity, the risk of CNAO and of CMAO without transfusion were significantly lower in individuals who labored, versus those who had a planned CD. · Labor in class III obesity: 21% fewer adverse neonatal outcomes.. · Class III obesity: 43% less maternal morbidity with labor.. · Labor in nulliparous individuals with class III obesity is safe..

Novel Approach to Identify Severe Maternal Morbidity Clusters: A Latent Class Analysis.

Whether clusters exist within severe maternal morbidity (SMM), a set of life-threatening heterogeneous conditions, is not known. Our primary objective was to identify SMM clusters using a data-driven clustering technique, their associated predictors and outcomes. From 2008 to 2017, we used a delivery database supplemented by state data and medical record abstraction from a single institution in Pennsylvania. To identify SMM clusters, we applied latent class modeling that included 23 conditions defined by 21 Centers for Disease Control SMM indicators, intensive care unit (ICU) admission, or prolonged postpartum length of stay. Logistic regression models estimated risk for SMM clusters and associations between clusters and maternal and neonatal outcomes. Among 97,492 deliveries, 2.7% (N = 2,666) experienced SMM by any of the 23 conditions. Four clusters were identified as archetypes of SMM. Deliveries labeled as Hemorrhage (37.7%, N = 1,004) were characterized by blood transfusions and sickle cell anemia; Critical Care (28.1%, N = 748) by ICU admission and amniotic embolism; Vascular (24.5%, N = 654) by cerebrovascular conditions; and Shock (9.8%, N = 260) by ventilatory support and shock. Hypertensive disorders of pregnancy, depression, and Medicaid insurance were associated with Shock cluster. People in all clusters had a high risk of maternal death within 1 year (odds ratio: 12.0, 95% confidence interval: 6.2-23). Infants born to those in the shock cluster had the highest odds of neonatal death, low Apgar scores, and neonatal ICU admission. We identified four novel SMM clusters that may help understand the collection of conditions defining SMM, underlying pathways and the importance of comorbidities such as depression and social determinants of health markers that amplify the well-established risk factors for SMM such as hypertensive disorders of pregnancy. · A total of 2.7% of deliveries experienced SMM events.. · There are four distinct SMM clusters: Hemorrhage, Critical Care, Vascular, and Shock.. · Not all SMM clusters bear the same risk for adverse perinatal outcomes..

The optic nerve sheath in hypertensive disorders of pregnancy and perinatal outcomes: a cohort study

BackgroundPreeclampsia is implicated in 14% of maternal deaths worldwide, mostly due to complications such as intracranial hemorrhage and cerebral edema. Cerebral edema increases intracranial pressure, which can be predicted by ultrasonographic measurement of the optic nerve sheath diameter (ONSD). Greater diameters have been reported in women with preeclampsia and eclampsia; however, data are lacking on the possible association with maternal and neonatal adverse outcomes. This study aimed to determine whether there is an association between hypertensive disorders of pregnancy and the ONSD, and between this measurement and maternal and neonatal adverse outcomes.MethodsThis was a cohort study involving 183 women in the third trimester of pregnancy or within 24 h following childbirth, distributed as follows: control group (n = 30), gestational hypertension (n = 14), chronic hypertension (n = 12), preeclampsia without severe features (n = 12), preeclampsia with severe features (n = 62), superimposed preeclampsia (n = 23) and eclampsia (n = 30). The participants underwent ocular ultrasonography, and data on maternal and neonatal outcomes were collected from the medical records. To compare the groups, analysis of variance was used for the normally distributed numerical variables and the Kruskal–Wallis test was used for variables with non-normal distribution. Two-tailed p-values ≤ 0.05 were considered statistically significant.ResultsOverall comparison between the seven groups showed no statistically significant difference in the mean ONSD (p = 0.056). Nevertheless, diameters were significantly greater in the eclampsia group compared to the control group (p = 0.003). Greater diameters were associated with maternal admission to the intensive care unit (ICU) (p < 0.01) and maternal near miss (p = 0.01). There was no association between ONSD and admission to the neonatal ICU (p = 0.1), neonatal near miss (p = 0.34) or neonatal death (p = 0.26).ConclusionsNo association was found between ONSD and the hypertensive disorders of pregnancy in the overall analysis; however, ONSD was greater in women with eclampsia compared to controls. Greater diameters were associated with maternal admission to the ICU and maternal near miss. These findings suggest a potential use for bedside ultrasound as an additional tool for stratifying risk in patients with hypertensive disorders of pregnancy.

Association of umbilical cord care practices with neonatal infection in Katsina, northwest Nigeria

Background: Significant numbers of neonatal deaths occurring each year are caused by infections that can be directly associated with improper and unhygienic umbilical cord care practices. The objectives of this study were to describe the umbilical cord care practices among mothers whose babies were admitted for suspected sepsis at the Federal Teaching Hospital and Turai Umaru Yar’adua Maternal and Children Hospital Katsina, Nigeria, assess the relationship between umbilical cord care practices and neonatal sepsis, and the influence of home delivery on this relationship. Methodology: This was a hospital-based descriptive observational study of 60 selected neonates with clinical features of sepsis admitted into the special care baby unit (SCBU) of the two hospitals between July and December 2022. The study involved the collection and microbiological analysis of blood samples using the BacT/Alert microbial detection system, and the administration of a structured questionnaire on the mother of each enrollee to collect relevant information about cord care practices. Data were analyzed using SPSS version 22.0. The Chisquare (x2) test and Odds ratio (with 95% confidence interval) were used to determine the association of risk factors with culture-confirmed sepsis, and a p value less than 0.05 was considered statistically significant. Results: Of the 60 neonates blood samples, 31 (51.7%) were culture-positive for neonatal sepsis while 29 (48.3%) were culture-negative. There was no statistically significant association between risk factors such as application of traditional materials for cord care and place of delivery, and culture-confirmed neonatal sepsis (p&gt;0.05). However, neonates whose mothers use traditional materials for cord care were more likely to develop sepsis than those who do not (OR=2.027, 95% CI=0.716-5.736). Concerning place of delivery, which is an important determinant of umbilical cord hygiene, babies delivered at home were almost 3 times more likely to have culture-confirmed sepsis than those delivered in the hospital (OR=2.975, 95% CI=1.040-8.510). A total of 26 out of the 60 (45.3%) mothers of the neonates agreed to have used unhygienic and traditional materials for cord care, with charcoal (39.0%), local herbs (27.0%), cow dung/urine concoction (19.0%), and others (15.0%), such as lubricants, ash, and balm, being the most commonly used materials for cord care. Conclusion: Neonatal infection is common among newborns in Federal Teaching Hospital and Turai Umaru Yar’adua Maternal and Children Hospital (TUYMCH), Katsina, northwest Nigeria, with a prevalence of culture-confirmed neonatal sepsis of 51.7%. Although there was no statistically significant association between unhygienic cord practices and neonatal sepsis in this study, babies whose mothers use traditional materials for cord care were more likely to develop sepsis. There is a high rate of use of harmful and unhygienic traditional materials for cord care in our environment. This habit can be discouraged through health education using the mass media and health talks in health facilities. The use of chlorhexidine, the recommended antiseptic for cord care by the World Health Organization and the Nigeria Federal Ministry of Health, should be encouraged.

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.

Prediction of pre-eclampsia with machine learning approaches: Leveraging important information from routinely collected data

BackgroundGlobally, pre-eclampsia (PE) is a leading cause of maternal and perinatal morbidity and mortality. PE prediction using routinely collected data has the advantage of being widely applicable, particularly in low-resource settings. Early intervention for high-risk women might reduce PE incidence and related complications. We aimed to replicate our machine learning (ML) published work predicting another maternal condition (gestational diabetes) to (1) predict PE using routine health data, (2) identify the optimal ML model, and (3) compare it with logistic regression approach. MethodsData were from a large health service network with 48,250 singleton pregnancies between January 2016 and June 2021. Supervised ML models were employed. Maternal clinical and medical characteristics were the feature variables (predictors), and a 70/30 data split was used for training and testing the model. Predictive performance was assessed using area under the curve (AUC) and calibration plots. Shapley value analysis assessed the contribution of feature variables. ResultsThe random forest approach provided excellent discrimination with an AUC of 0.84 (95% CI: 0.82–0.86) and highest prediction accuracy (0.79); however, the calibration curve (slope of 1.21, 95% CI 1.13–1.30) was acceptable only for a threshold of 0.3 or less. The next best approach was extreme gradient boosting, which provided an AUC of 0.77 (95% CI: 0.76–0.79) and well-calibrated (slope of 0.93, 95% CI 0.85–1.01). Logistic regression provided good discrimination performance with an AUC of 0.75 (95% CI: 0.74–0.76) and perfect calibration. Nulliparous, pre-pregnancy body mass index, previous pregnancy with prior PE, maternal age, family history of hypertension, and pre-existing hypertension and diabetes were the top-ranked features in Shapley value analysis. ConclusionTwo ML models created the highest-performing prediction using routinely collected data to identify women at high risk of PE, with acceptable discrimination. However, to confirm this result and also examine model generalisability, external validation studies are needed in other settings, utilising standardised prognostic factors.

Cesarean delivery in a tertiary institution of the Republic of Moldova: analysis using the Robson classification

BackgroundThe worldwide rise in cesarean section rate is a major public health concern and cause of significant debate. Despite multiple studies showing that higher cesarean rates may be associated with adverse maternal and perinatal outcomes, the number of cesarean births increases continuously. In the Republic of Moldova, the cesarean section has increased from 15.75% in 2012 to 27.42% in 2022, however, the perinatal mortality remains unchanged - constituting 11.6‰. In order to understand the factors that determine the increasing trend of cesarean section and to approach new strategies to reduce unnecessary surgical delivery, a standardized tool is needed to assess and compare cesarean section rates. ObjectiveTo assess changes in cesarean section rates and trends and to evaluate the contribution of different obstetrical populations to overall cesarean rates in Municipal Clinical Hospital using the Robson Classification. Study DesignA cohort study conducted at the Municipal Clinical Hospital in Chisinau. The study includes 13882 women who gave birth in 2017, 2019, and 2022 in this hospital. All births were classified into 10 Robson groups, using six basic variables (parity, cesarean section delivery in medical history, labor onset, number of fetuses, gestational age, and fetal presentation). Statistical data were collected and analyzed using the Epi INFO program. ResultsThe overall cesarean section rate was 20.02% (2779/13882) with a significant increase from 18.59% (809/4351) to 21.59% (1134/5252), P=0.0003. Approximately one-third 39.55% (1099/2279) of all cesarean deliveries were performed before the labor onset. The main contributor in all study years is Group 5 - 34.44% (957/2779). The next valuable group as a contributor to the overall cesarean rate are the women from Group 2 representing 14.14% (393/2779), followed by women of Group 1 with 11.98% (333/2779). ConclusionsThe use of the Robson Ten-groups classification offers a clear and detailed record of the cesarean section trends, and due to its simplicity and exclusivity, it can be implemented in the Republic of Moldova as well. The main contributors to the overall cesarean rate are women with a previous cesarean delivery - Group 5, followed by nulliparous women of Group 2 and Group 1.

7828 First Trimester Serum 11-Deoxycorticosterone Predicts Extreme Premature Childbirth

Abstract Disclosure: E.K. Ronde Salminen: None. S. Schoenmakers: None. B.D. van Zelst: None. S.A. van den Berg: None. First Trimester Serum 11-Deoxycorticosterone Predicts Extreme Premature Childbirth Background: Preterm birth is the leading cause of perinatal mortality and morbidity worldwide. Unfortunately, the prediction of preterm birth remains challenging, causing unnecessary hospital admittance and overexposure to medication. Studies have shown that metabolites of progesterone can influence uterine contractility[1] and serum levels of 11-deoxycorticosterone have been shown to correlate with an increased risk of preterm birth before 32 weeks of gestation2. The aim of this prospective study was to determine whether first trimester measurement of the progesterone metabolites 11-deoxycorticosterone (11-DOC) and 16-alpha hydroxyprogesterone (16-OHP) could be used as a predictive marker for preterm birth. Methods and results: A cohort of 386 pregnant women were included at 12 weeks of gestation between 2014-2016. Their obstetric histories and comorbidities were noted and their plasma was frozen. Of these women, n=26 delivered prior to 32 weeks of gestation and n=286 delivered at term. 11-DOC and 16-OHP were determined using LC-MS/MS. Mann-Whitney U test was used to statistically analyze differences between the groups. There was a highly significant difference in the level of 11-DOC between women delivering prior to 32 weeks of gestation in comparison to women delivering after 37 weeks of gestation (p=0.007). 16-OHP levels tended to be different between the two groups, but this did not reach statistical significance (p=0.062). No difference was found in the ratio 16-alpha hydroxyprogesterone/11-deoxycorticosterone between the two groups (p=0.916). Conclusion: Plasma levels of progesterone metabolites collected late in the first trimester of pregnancy predicts preterm birth prior to 32 weeks of pregnancy.

Placental Malaria Induces a Unique Methylation Profile Associated with Fetal Growth Restriction.

Fetal growth restriction (FGR) is associated with perinatal death and adverse birth outcomes, as well as long-term complications, including increased childhood morbidity, abnormal neurodevelopment, and cardio-metabolic diseases in adulthood. Placental epigenetic reprogramming associated with FGR may mediate these long-term outcomes. Placental malaria (PM), characterized by sequestration of Plasmodium falciparum-infected erythrocytes in placental intervillous space, is the leading global cause of FGR, but its impact on placental epigenetics is unknown. We hypothesized that placental methylomic profiling would reveal common and distinct mechanistic pathways of non-malarial and PM-associated FGR. We analyzed placentas from a US cohort with no malaria exposure (n = 12) and a cohort from eastern Uganda, a region with a high prevalence of malaria (n = 12). From each site, 8 cases of FGR (defined as birth weight <10%ile for gestational age by Intergrowth-21 standard curves) and 4 healthy controls with normal weight were analyzed. PM was diagnosed by placental histopathology. We compared the methylation levels of over 850K CpGs of the placentas using Infinium MethylationEPIC v1 microarray. Non-malarial FGR was associated with 65 differentially methylated CpGs (DMCs), whereas PM-FGR was associated with 133 DMCs, compared to their corresponding controls without FGR. One DMC (cg16389901, located in the promoter region of BMP4) was commonly hypomethylated in both groups. We identified 522 DMCs between non-malarial FGR vs. PM-FGR placentas, which was independent of differing geographic location or cellular composition. Placentas with PM-associated FGR have distinct methylation profiles as compared to placentas with non-malarial FGR, suggesting novel epigenetic reprogramming in response to malaria. Larger cohort studies are needed to determine the distinct long-term health outcomes in PM-associated FGR pregnancies.

Reconstructing infant mortality in Iberian Iron Age populations from tooth histology

The Neonatal Line (NNL) of the tooth serves as a unique identifier, allowing us to distinguish whether a child survived birth. This line is essential for assessing the age at death of infants from skeletal remains found in archaeological contexts. Our primary objective is to accurately determine the age of infant intramural inhumations from the Iberian Iron Age (8th-1st centuries BC) by analyzing histological sections of tooth germs. Due to their fragility and high susceptibility to taphonomic factors, these samples are challenging to handle. By accurately assessing their age, we aim to classify individuals into various stages of infant mortality, which will help reconstruct infant mortality patterns in these populations.We analyze unerupted and still-forming crown deciduous teeth from 45 infant burials. By calculating Crown Formation Time (CFT) and identifying the NNL, we determine both gestational and chronological ages. We further validate the reliability of NNL identification through Synchrotron X-ray Fluorescence (SXRF) elemental analysis (Ca, Zn, Cu) on two contemporary and two archaeological samples.Our histological study reveals the chronological age of 38 infants from Iberian settlements, ranging from the 30th week of gestation to the 2nd postnatal month. The age distribution shows an attritional mortality pattern, with nearly half experiencing perinatal mortality, including preterm births. These findings support the hypothesis that mortality was primarily attributed to natural causes. Our research enhances the understanding of infant life history events in prehistory by combining histological analysis of tooth NNL and CFT, highlighting the technique's potential and limitations.

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.

Quality of neonatal health care in comprehensive specialized hospitals, Amhara Region, Ethiopia: a retrospective study with neonatal death audit

BackgroundNeonatal health is one of the targets for the sustainable development goals (SDGs) that aim to reduce neonatal mortality to at least as low as 12 per 1 000 live births in 2030. However, the world is not on track to achieve this target. The problem has worsened in many low-income countries, including Ethiopia, due to a fragile health system, as well as health crises such as the COVID-19 pandemic, conflict, food insecurity and climate change. According to the Mini Ethiopian Demographic Health Survey, neonatal mortality is unacceptably high in Ethiopia in general, and in Amhara region in particular. Despite these facts, there is a paucity of information on the quality of neonatal health service provision in comprehensive specialized hospitals in Amhara region. Therefore, this study is aimed at assessing the quality of neonatal health services in terms of outcome (neonatal mortality) and its causes in comprehensive specialized hospitals in Amhara region.MethodsA multi-center retrospective study was conducted (from September 1–30/2022) on 315 neonates in four comprehensive hospitals with chart review. Data were collected through death audit with standardized neonatal death audit tool. Data were entered into Epi-data 3.1 and exported to SPSS 20 for analysis. Descriptive analysis was used to describe and summarize the data in an informative manner.ResultsFrom 315 neonatal deaths, about two-thirds, 205 (65.1%), were from rural areas. Nearly half, 151 (48%), of the mothers had complications and delivered outside a health facility. About 36 (11.4%), 45 (14.3%), and 21 (6.7%) neonates’ mothers had 1st, 2nd, and 3rd delays, respectively. About 59 (19%) of mothers had membrane rupture before the onset of labor and 23 (7.3%) had meconium-stained liquor. Almost three-fourths, 226 (71.7%), of the deaths were low birth weight (< 2500 gram). About 25 (8%) of neonates had congenital anomalies, 65% of them had fast breathing and 54.6% were preterm.ConclusionHigher proportions of neonatal deaths were observed among neonates with rural residence, low birth weight, mothers’ complications and neonates admitted for fast breathing. Histories of abortion, complications, congenital anomalies, and the 3 delays contributed to neonatal deaths.
