Association between decision-to-delivery time and neonatal outcomes: a systematic review and meta-analysis.

BACKGROUND: Decision-to-delivery time (DDT), a crucial factor during the emergency caesarean section, may potentially impact neonatal outcomes. This study aims to assess the association between DDT and various neonatal outcomes. METHODS: A comprehensive search of PubMed, Scopus, Cochrane Library, and Google Scholar databases was conducted. A total of 32 eligible studies that reported on various neonatal outcomes, such as Apgar score, acidosis, neonatal intensive unit (NICU) admissions and mortality were included in the review. Studies were selected based on predefined eligibility criteria, and a random-effects inverse-variance model with DerSimonian-Laird estimate of tau² was used for meta-analysis. Heterogeneity and publication bias were assessed using I² statistics and Egger's test, respectively. RESULTS: The meta-analysis revealed a significant association between DDT < 30 min and increased risk of Apgar score < 7 (OR 1.803, 95% CI: 1.284-2.533) and umbilical cord pH < 7.1 (OR 4.322, 95% CI: 2.302-8.115), with substantial heterogeneity. No significant association was found between DDT and NICU admission (OR 0.982, 95% CI: 0.767-1.258) or neonatal mortality (OR 0.983, 95% CI: 0.565-1.708), with negligible heterogeneity. Publication bias was not detected for any outcomes. CONCLUSIONS: This study underscores the association between shorter DDT and increased odds of adverse neonatal outcomes such as low Apgar scores and acidosis, while no significant association was found in terms of NICU admissions or neonatal mortality. Our findings highlight the complexity of DDT's impact, suggesting the need for nuanced clinical decision-making in cases of emergency caesarean sections.

The benefit of active management in true knot of the umbilical cord: a retrospective study.

PURPOSE: To compare perinatal outcomes between active and routine management in true knot of the umbilical cord (TKUC). METHODS: A retrospective study of singletons born beyond 22 6/7 weeks with TKUC. Active management included weekly fetal heart rate monitoring(FHRM) ≥ 30 weeks and labor induction at 36-37 weeks. Outcomes in active and routine management were compared, including composite asphyxia-related adverse outcome, fetal death, labor induction, Cesarean section (CS) or Instrumental delivery due to non-reassuring fetal heart rate (NRFHR), Apgar5 score < 7, cord Ph < 7, neonatal intensive care unit (NICU) admission and more. RESULTS: The Active (n = 59) and Routine (n = 1091) Management groups demonstrated similar rates of composite asphyxia-related adverse outcome (16.9% vs 16.8%, p = 0.97). Active Management resulted in higher rates of labor induction < 37 weeks (22% vs 1.7%, p < 0.001), CS (37.3% vs 19.2%, p = 0.003) and NICU admissions (13.6% vs 3%, p < 0.001). Fetal death occurred exclusively in the Routine Management group (1.8% vs 0%, p = 0.6). CONCLUSION: Compared with routine management, weekly FHRM and labor induction between 36 and 37 weeks in TKUC do not appear to reduce neonatal asphyxia. In its current form, active management is associated with higher rates of CS, induced prematurity and NICU admissions. Labor induction before 37 weeks should be avoided.

Neonatal outcomes in term and preterm infants following adjunctive azithromycin antibiotic prophylaxis for non-elective cesarean delivery.

OBJECTIVE: It is currently unknown whether adjunctive azithromycin prophylaxis at the time of non-elective cesarean has differential effects on neonatal outcomes in the context of prematurity. The objective of this study was to compare whether neonatal outcomes differ in term and preterm infants exposed to adjunctive azithromycin prophylaxis before non-elective cesarean delivery. STUDY DESIGN: A planned secondary analysis of a multi-center randomized controlled trial that enrolled women with singleton pregnancies ≥24 weeks gestation undergoing non-elective cesarean delivery (during labor or ≥4 h after membrane rupture). Women received standard antibiotic prophylaxis and were randomized to either adjunctive azithromycin (500 mg) or placebo. The primary composite outcome was neonatal death, suspected or confirmed neonatal sepsis, and serious neonatal morbidities (NEC, PVL, IVH, BPD). Secondary outcomes included NICU admission, neonatal readmission, culture positive infections and prevalence of resistant organisms. Odds ratios (OR) for the effect of azithromycin versus placebo were compared between gestational age strata (preterm [less than 37 weeks] versus term [37 weeks or greater]). Tests of interaction examined homogeneity of treatment effect with gestational age. RESULTS: The analysis includes 2,013 infants, 226 preterm (11.2%) and 1,787 term. Mean gestational ages were 34 and 39.5 weeks, respectively. Within term and preterm strata, maternal and delivery characteristics were similar between the azithromycin and placebo groups. There was no difference in the odds of composite neonatal outcome between those exposed to azithromycin versus placebo in preterm neonates (OR 0.82, 95% CI 0.48-1.41) and in term neonates (OR 1.06, 95% CI 0.77-1.46), with no difference between gestational age strata (p = 0.42). Analysis of secondary outcomes also revealed no differences in treatment effects within or between gestational age strata. CONCLUSION: Exposure to adjunctive azithromycin antibiotic prophylaxis for non-elective cesarean delivery does not increase neonatal morbidity or mortality in term or preterm infants.

Factors Affecting Mode of Birth in Women With Preexisting Diabetes and Gestational Diabetes: A Retrospective Cohort at a Tertiary Referral Center.

Women with preexisting diabetes and gestational diabetes mellitus (GDM) are at higher risk for adverse maternal and neonatal outcomes. However, there is no consensus on a uniform approach regarding mode of birth (MOB) for all forms of diabetes. The aim of the study is to compare MOB in women with preexisting diabetes and GDM and possible factors influencing it. A retrospective cohort study of women with GDM and preexisting diabetes between 2015 and 2021 at a tertiary referral center was conducted. One thousand three hundred eighty-five singleton pregnancies were included. One thousand twenty-two (74.4%) women had a vaginal birth (VB) and 351 (25.6%) a caesarean section. Preexisting diabetes was significantly associated with caesarean section compared to GDM (OR 2.43). Five hundred fifty-one (40.1%) women underwent induction of labor, and 122 (22.1%) women had a secondary caesarean after IOL. Women induced due to spontaneous rupture of membrane (SROM) achieved the highest rate of VB at 93%. The lowest rates of VB occurred if indication for induction was for preeclampsia or hypertension. IOL was significantly less successful in preexisting diabetes with a VB achieved in 56.4% for type 1 diabetes and 52.6% of type 2 diabetes compared to GDM (78.2% in GDM; 81.2% in IGDM; OR 3.25, 95% CI 1.70-6.19, p < 0.001). The rate of VB was higher who were induced preterm compared to women with term IOL (n = 240 (81.9%) vs. n = 199 (73.2%); p < 0.05). Parity, previous VB and SROM favored VB after IOL, whereas preexisting diabetes, hypertension, and IOL after 40 + 0 weeks are independent risk factors for caesarean delivery.

Pregnancy Outcomes in Women with Poorly Controlled Pregestational Diabetes Mellitus.

BACKGROUND: The prevalence of pregestational diabetes mellitus (PGDM) in women of reproductive age has surged globally, contributing to increased rates of adverse pregnancy outcomes. Hemoglobin A1c (HbA1c) is a crucial marker for diagnosing and monitoring PGDM, with periconceptional levels influencing the risk of congenital anomalies and complications. OBJECTIVES: To evaluate the association between periconceptional HbA1c levels and perinatal complications in pregnant women with poorly controlled PGDM. METHODS: We conducted a retrospective analysis of prospectively collected data of pregnancies between 2010 and 2019, HbA1c > 6% at 3 months prior to conception or during the first trimester. Outcomes of periconceptional HbA1c levels were compared. RESULTS: The cohort included 89 women: 49 with HbA1c 6-8%, 29 with HbA1c 8-10%, and 11 with HbA1c > 10%. Higher HbA1c levels were more prevalent in type 1 diabetics and were associated with increased end-organ damage risk. Women with elevated HbA1c levels tended toward unbalanced glucose levels during pregnancy. The cohort exhibited high rates of preterm delivery, hypertensive disorders, cesarean delivery, and neonatal intensive care unit admission. Overall live birth rate was 83%. While a significant correlation was found between HbA1c levels and preterm delivery, no consistent association was observed with other adverse outcomes. CONCLUSIONS: Periconceptional glycemic control in PGDM pregnancies is important. Elevated HbA1c levels are associated with increased risks of adverse outcomes. Beyond a certain HbA1c level, risks of complications may not proportionally escalate.

Postpartum length of hospital stay among obstetric patients in Ibadan, Nigeria.

BACKGROUND: Postpartum Length of hospital stay (PLOHS) is an essential indicator of the quality of maternal and perinatal healthcare services. Identifying the factors associated with PLOHS will inform targeted interventions to reduce unnecessary hospitalisations and improve patient outcomes after childbirth. Therefore, we assessed the length of hospital stay after birth and the associated factors in Ibadan, Nigeria. METHODS: We used the Ibadan Pregnancy Cohort Study (IbPCS) data, and examined the 1057 women who had information on PLOHS the mode of delivery [spontaneous vagina delivery (SVD) or caesarean section (C/S)]. The outcome variable was PLOHS, which was described as the time interval between the delivery of the infant and discharge from the health facility. PLOHS was prolonged if > 24 h for SVD and > 96 h for C/S, but normal if otherwise. Data were analysed using descriptive statistics, a chi-square test, and modified Poisson regression. The prevalence-risk ratio (PR) and 95% confidence interval (CI) are presented at the 5% significance level. RESULTS: The mean maternal age was (30.0 ± 5.2) years. Overall, the mean PLOHS for the study population was 2.6 (95% CI: 2.4-2.7) days. The average PLOHS for women who had vaginal deliveries was 1.7 (95%CI: 1.5-1.9) days, whereas those who had caesarean deliveries had an average LOHS of 4.4 (95%CI: 4.1-4.6) days. About a third had prolonged PLOHS: SVD 229 (32.1%) and C/S 108 (31.5%). Factors associated with prolonged PLOHS with SVD, were high income (aPR = 1.77; CI: 1.13, 2.79), frequent ANC visits (> 4) (aPR = 2.26; CI: 1.32, 3.87), and antenatal admission: (aPR = 1.88; CI: 1.15, 3.07). For C/S: maternal age > 35 years (aPR = 1.59; CI: 1.02, 2.47) and hypertensive disease in pregnancy (aPR = 0.61 ; CI: 0.38, 0.99) were associated with prolonged PLOHS. CONCLUSION: The prolonged postpartum length of hospital stay was common among our study participants occurring in about a third of the women irrespective of the mode of delivery. Maternal income, advanced maternal age, ANC related issues were predisposing factors for prolonged LOHS. Further research is required to examine providers' perspectives on PLOHS among obstetric patients in our setting.

Deep neural network (DNN) modelling for prediction of the mode of delivery.

One of the factors that worry obstetricians the most is the method of delivery. In recent years, the rate of caesarean sections has steadily climbed and now exceeds the threshold advised by medical organizations. Obstetricians typically lack the tools they need to assess whether vaginal delivery or a caesarean delivery is more appropriate. In this work, we suggested a computerized decision-making process for deciding on the best birthing style. The data was collected from 101 pregnant subjects who were admitted to hospital in eastern India for delivery from January 2021 to September 2021.The data set had 101 instances & 11 variables. The response was a binary variable with "caesarean" & "vaginal" as the outputs. A deep neural network model (DNN) was developed by using train set with h2o package. The model was selected on the basis of AUC (Area under the Curve) & KS (Kolmogorov-Smirnov) score. The AUC, KS score for train set were 0.99, 0.98 respectively. The prediction error rates for caeseraen & vaginal classes in train data are 0.02 & 0.00 respectively. The results support the use of these algorithms in the creation of a clinical decision system to help gynaecologists choose the most appropriate delivery method.

Caesarean section delivery rates and associated factors in a faith-based referral hospital in Ghana: A retrospective analysis.

INTRODUCTION: The global incidence of caesarean section (CS) deliveries has exceeded the recommended threshold set by the World Health Organization. This development is a matter of public health concern due to the cost involved and the potential health risk to the mother and the neonate. We sought to investigate the prevalence, indications, maternal and neonatal outcomes and determinants of CS in private health facilities in Ghana. METHOD: A retrospective cross-sectional analysis was conducted using data from women who delivered at the Holy Family Hospital from January to February 2020 using descriptive and inferential statistics, with a significance level set at p<0.05. RESULTS: The prevalence of CS was 28.70%. The primary indications of C/S include previous C/S, foetal distress, breech presentation, pathological CTG and failed induction. Significant associations were found between CS and breech presentation (AOR = 4.60; 95%CI: 1.22-17.38) p<0.024, previous CS history (AOR = 51.72, 95% CI: 11.59-230.70) p<0.00, and neonates referred to NICU (AOR = 3.67, 95% CI: 2.10-6.42) p<0.00. CONCLUSION: The prevalence of caesarean section (CS) deliveries was higher than the WHO-recommended threshold. Major indications for CS included previous CS, fetal distress, and failed induction. Significant risk factors for CS were previous CS history, breech presentation, and neonates referred to NICU.

Prevalence of emergency caesarean delivery and its predictors among women who give birth in Ethiopia using further analysis of EDHS 2016 data: A mixed effect model.

INTRODUCTION: Emergency caesarean delivery is a surgical procedure that is decided after the labour pain has started. According to the global report of the World Health Organization, the rate of caesarean sections has risen over time. In Ethiopia, the overall caesarean delivery was 18%, which varied between 46% in the private sector and 15% in the public sector. But specifically, the magnitude of emergency caesarean delivery and its predictors are not well addressed in Ethiopia. Therefore, this study was aimed at assessing the prevalence and predictors of emergency caesarean delivery in Ethiopia using EDHS 2016. METHOD: A cross-sectional study was used, and a total of 11,022 samples were included in this study. The Ethiopian Demographic Health Survey 2016 data set was used as a data source. The STATA version 17 software was used for descriptive, bi-variable, and multivariable analysis. Multilevel binary logistic regression was used to identify the significant factors at a p-value of <0.05 and a 95% confidence level. Model comparison and goodness of fit was assessed by AIC. RESULTS: The prevalence of emergency caesarean deliveries in Ethiopia was 1.2% (95% CI: 0.58, 1.78). History of fistula (AOR = 7.82, 95% CI: 1.59-38.4), age ≥ 35 years (AOR = 6.98, 95% CI: 3.33-14.63), and rural residence (AOR = 2.23, 95% CI: 1.25-3.21) were the predictors of emergency caesarean delivery. CONCLUSION: As compared to the previous study, the prevalence of emergency caesarean delivery was low. Women with a history of fistula, from rural residence, and age≥ 35 years were at risk for emergency caesarean delivery. Therefore, interventions need to be encouraged to give attention to rural women whose age is ≥ 35 years and fistula reduction activities, such as avoiding early marriage, to reverse the problem. Early and accurate screening of women for emergency cesarean delivery by encouraging co-services like ANC is also recommended.

Association between location of prenatal care services and non-consented cesarean sections in Mexico: A secondary analysis of the National Survey on the Dynamics of Household Relationships 2016.

BACKGROUND: Mexico has one of the world's highest rates of cesarean section (C-section). Little is known about Mexico's frequency of and risk factors for non-consented C-sections, a form of obstetric violence. We examined the prevalence of sociodemographic and obstetric-specific characteristics of Mexican women who delivered via C-section, as well as the association between the location of prenatal care services and experiencing a non-consented C-section. METHODS: We conducted a secondary analysis of data collected from Mexico's 2016 National Survey on the Dynamics of Household Relationships (ENDIREH 2016) of women who reported a C-section during their latest delivery. Adjusted logistic regressions were calculated to explore the associations between the location of prenatal care services and experiencing a non-consented cesarean delivery, stratifying by Indigenous belonging. RESULTS: The sample size for this analysis was 10,256 ENDIREH respondents, with 9.1% not consenting to a C-section. ENDIREH respondents between the ages of 26 and 35 years old, living in urban settings, living in Central or Southern Mexico, and married or living with a partner experienced a higher prevalence of non-consented C-sections. For both women who identified as Indigenous and those who did not, the odds of experiencing a non-consented C-section were higher when receiving prenatal services in private settings. Receiving more than one type of prenatal service was also associated with increased odds of non-consented C-sections, while ENDIREH 2016 respondents who did not identify as Indigenous and received prenatal care at the State Institute for Social Security and Services for State Workers facility had lower odds of experiencing a non-consented C-section. CONCLUSIONS: This analysis indicates that receiving prenatal care at a private facility or a combination of public and private services increases the risk of experiencing a non-consented C-section in Mexico. Additional research is required to further understand the factors associated with non-consented C-sections in Mexico.

Obstetric risk profiles and causes of death: Estimating their association with cesarean sections among maternal deaths in Mexico.

BACKGROUND: Maternal mortality is a critical indicator of healthcare quality, and in Mexico, this has become increasingly concerning due to the stagnation in its decline, alongside a concurrent increase in cesarean section (C-section) rates. This study characterizes maternal deaths in Mexico, focusing on estimating the association between obstetric risk profiles, cause of death, and mode of delivery. METHODS: Utilizing a retrospective observational design, 4,561 maternal deaths in Mexico from 2010-2014 were analyzed. Data were sourced from the Deliberate Search and Reclassification of Maternal Deaths database, alongside other national databases. An algorithm was developed to extract the Robson Ten Group Classification System from clinical summaries text, facilitating a nuanced analysis of C-section rates. Information on the reasons for the performance of a C-section was also obtained. Logistic regression and multinomial logistic regression models were used to estimate the relation between obstetric risk factors, mode of delivery and causes of maternal death, adjusting for covariates. RESULTS: Among maternal deaths in Mexico from 2010-2014, 47.1% underwent a C-section, with a significant history of previous C-sections observed in 31.4% of these cases, compared to 17.4% for vaginal deliveries (p<0.001). Early prenatal care in the first trimester was more common in C-section cases (46.8%) than in vaginal deliveries (38.3%, p<0.001). A stark contrast was noted in the place of death, with 82.4% of post-C-section deaths occurring in public institutions versus 69.1% following vaginal births. According to Robson's classification, the highest C-section rates were in Group 4 (67.2%, p<0.001) and Group 8 (66.9%, p<0.001). Logistic regression analysis revealed no significant difference in the odds of receiving a C-section in private versus other settings after adjusting for Robson criteria (OR: 1.21; 95% CI: 0.92, 1.60). A prior C-section significantly increased the likelihood of another (OR: 2.38; CI 95%: 2.01, 2.81). The analysis also indicated C-sections were significantly tied to deaths from hypertensive disorders (RRR = 1.25, 95% CI [1.12, 1.40]). In terms of indications, 6.3% of C-sections were performed under inadequate indications, while the indication was not identifiable in 33.1% of all C-sections. CONCLUSIONS: This study highlights a significant overuse of C-sections among maternal deaths in Mexico (2010-2014), revealed through the Robson classification and ana analysis of the reported indications for the procedure. It underscores the need for revising clinical decision-making to promote evidence-based guidelines and favor vaginal deliveries when possible. High C-section rates, especially noted disparities between private and public sectors, suggest economic and non-clinical factors may be at play. The importance of accurate data systems and further research with control groups to understand C-section practices' impact on maternal health is emphasized.

Caesarean delivery and neonatal mortality: evidence from selected slums in and around Dhaka city, Bangladesh- A prospective cohort study.

BACKGROUND: This study examined the neonatal mortality for newborn of women who delivered by caesarean section or vaginally using a prospective cohort. METHODS: A total of 6,989 live births registered from 2016 to 2018, were followed for neonatal survival from the selected slums of Dhaka (North and South) and Gazipur city corporations, where icddr,b maintained the Health and Demographic Surveillance System (HDSS). Neonatal mortality was compared by maternal and newborn characteristics and mode of delivery using z-test. Logistic regression model performed for neonatal mortality by mode of delivery controlling selected covariates and reported adjusted odd ratios (aOR) with 95% confidence interval (CI). RESULTS: Out of 6,989 live births registered, 27.7% were caesarean and the rest were vaginal delivery; of these births, 265 neonatal deaths occurred during the follow-up. The neonatal mortality rate was 2.7 times higher (46 vs. 17 per 1,000 births) for vaginal than caesarean delivered. Until 3rd day of life, the mortality rate was very high for both vaginal and caesarean delivered newborn; however, the rate was 24.8 for vaginal and 6.3 per 1,000 live births for caesarean delivered on the 1st day of life. After adjusting the covariates, the odds of neonatal mortality were higher for vaginal than caesarean delivered (aOR: 2.63; 95% CI: 1.82, 3.85). Additionally, the odds were higher for adolescent than elderly adult mother (aOR: 1.60; 95% CI: 1.03, 2.48), for multiple than singleton birth (aOR: 5.40; 95% CI: 2.82, 10.33), for very/moderate (aOR: 5.13; 95% CI: 3.68, 7.15), and late preterm birth (aOR: 1.48; 95% CI: 1.05, 2.08) than term birth; while the odds were lower for girl than boy (aOR: 0.74; 95% CI: 0.58, 0.96), and for 5th wealth quintile than 1st quintile (aOR: 0.59, 95% CI: 0.38, 0.91). CONCLUSION: Our study found that caesarean delivered babies had significantly lower neonatal mortality than vaginal delivered. Therefore, a comprehensive delivery and postnatal care for vaginal births needed a special attention for the slum mothers to ensure the reduction of neonatal mortality.

The impact of caesarean scar niche on fertility - a systematic review.

BACKGROUND: The trend of increasing caesarean section (CS) rates brings up questions related to subfertility. Research regarding the influence of CS on assisted reproduction techniques (ART) is conflicting. A potential mechanism behind CS-induced subfertility is intra uterine fluid resulting from a caesarean scar defect or niche. The vaginal microbiome has been repeatedly connected to negative ART outcomes, but it is unknown if the microbiome is changed in relation to a niche. METHODS: This systematic review describes literature investigating the effect of a niche on live birth rates after assisted reproduction. Furthermore, studies investigating a difference in microbial composition in subfertile persons with a niche compared to no niche are evaluated. Pubmed, Embase and Web of Science were searched on March 2023 for comparative studies on both study questions. Inclusion criteria were i.e., English language, human-only studies, availability of the full article and presence of comparative pregnancy data on a niche. The quality of the included studies and their risk of bias were assessed using the Newcastle-Ottawa scale for cohort studies. The results were graphically displayed in a forest plot. RESULTS: Six retrospective cohort studies could be included on fertility outcomes, with a total of 1083 persons with a niche and 3987 without a niche. The overall direction of effect shows a negative impact of a niche on the live birth rate (pooled aOR 0.58, 95% CI 0.48-0.69) with low-grade evidence. Three studies comparing the microbiome between persons with and without a CS could be identified. CONCLUSION: There is low-grade evidence to conclude that the presence of a niche reduces live birth rates when compared to persons without a niche. The theory that a caesarean has a negative impact on pregnancy outcomes because of dysbiosis promoted by the niche is interesting, but there is no sufficient literature about this.

The increasing number of caesarean deliveries has raised concerns about how it might affect a woman's ability to get pregnant afterwards. Some studies suggest that having a caesarean section (CS) could make it harder to conceive, particularly through in vitro fertilisation (IVF). The reason could be the scar or niche from a previous caesarean. This niche can cause fluid inside the uterus. We also know that the mix of bacteria in the vagina, called the vaginal microbiome, can affect a woman's chances of getting pregnant, especially with treatments like IVF. But we are not sure if having a caesarean affects the vaginal microbiome.To understand this better, van den Tweel's team looked at studies on whether having a niche from a caesarean affects a woman's chance of having a baby through IVF. They also looked at studies comparing the bacteria in the vagina of women who have had a caesarean with those who have not. They found that having a caesarean niche makes it harder for a woman to have a baby through IVF. However, the evidence from these studies is not very strong. We still do not know enough about whether having a caesarean niche affects the bacteria in the vagina.

Determinants of severe maternal outcome in Keren hospital, Eritrea: An unmatched case-control study.

BACKGROUND: In the past few decades, several studies on the determinants and risk factors of severe maternal outcome (SMO) have been conducted in various developing countries. Even though the rate of maternal mortality in Eritrea is among the highest in the world, little is known regarding the determinants of SMO in the country. Thus, the aim of this study was to identify determinants of SMO among women admitted to Keren Provincial Referral Hospital. METHODS: A facility based unmatched case-control study was conducted in Keren Hospital. Women who encountered SMO event from January 2018 to December 2020 were identified retrospectively from medical records using the sub-Saharan Africa maternal near miss (MNM) data abstraction tool. For each case of SMO, two women with obstetric complication who failed to meet the sub-Saharan MNM criteria were included as controls. Bivariate and multivariate logistic regression analyses were employed using SPSS version-22 to identify factors associated with SMO. RESULTS: In this study, 701 cases of SMO and 1,402 controls were included. The following factors were independently associated with SMO: not attending ANC follow up (AOR: 4.53; CI: 3.15-6.53), caesarean section in the current pregnancy (AOR: 3.75; CI: 2.69-5.24), referral from lower level facilities (AOR: 11.8; CI: 9.1-15.32), residing more than 30 kilometers away from the hospital (AOR: 2.97; CI: 2.29-3.85), history of anemia (AOR: 2.36; CI: 1.83-3.03), and previous caesarean section (AOR: 3.49; CI: 2.17-5.62). CONCLUSION: In this study, lack of ANC follow up, caesarean section in the current pregnancy, referral from lower facilities, distance from nearest health facility, history of anaemia and previous caesarean section were associated with SMO. Thus, improved transportation facilities, robust referral protocol and equitable distribution of emergency facilities can play vital role in reducing SMO in the hospital.

Obstetric and haematological management and outcomes of women with placenta accreta spectrum by planned or urgent delivery: Secondary data analysis of a public referral hospital in Lebanon.

BACKGROUND: Lebanon has a high caesarean section use and consequently, placenta accreta spectrum (PAS) is becoming more common. OBJECTIVES: To compare maternal characteristics, management, and outcomes of women with PAS by planned or urgent delivery at a major public referral hospital in Lebanon. DESIGN: Secondary data analysis of prospectively collected data. SETTING: Rafik Hariri University Hospital (public referral hospital), Beirut, Lebanon. PARTICIPANTS: 159 pregnant and postpartum women with confirmed PAS between 2007-2020. MAIN OUTCOME MEASURES: Maternal characteristics, management, and maternal and neonatal outcomes. RESULTS: Out of the 159 women with PAS included, 107 (67.3%) underwent planned caesarean delivery and 52 (32.7%) had urgent delivery. Women who underwent urgent delivery for PAS management were more likely to experience antenatal vaginal bleeding compared to those in the planned group (55.8% vs 28.0%, p<0.001). Median gestational age at delivery was significantly lower for the urgent group compared to the planned (34 vs. 36 weeks, p<0.001). There were no significant differences in terms of blood transfusion rates and major maternal morbidity between the two groups; however, median estimated blood loss was significantly higher for women with urgent delivery (1500ml vs. 1200ml, p = 0.011). Furthermore, the urgent delivery group had a significantly lower birth weight (2177.5g vs. 2560g, p<0.001) with higher rates of neonatal intensive care unit (NICU) admission (53.7% vs 23.8%, p<0.001) and perinatal mortality (18.5% vs 3.8%, p = 0.005). CONCLUSION: Urgent delivery among women with PAS is associated with worse maternal and neonatal outcomes compared to the planned approach. Therefore, early referral of women with known or suspected PAS to specialized centres is highly desirable to maximise optimal outcomes for both women and infants.

Maternal and fetal outcomes after planned cesarean or vaginal delivery in twin pregnancy: a comparison between 2 third level birth centers.

BACKGROUND: Twin pregnancy is associated with higher risks of adverse perinatal outcomes for both the mother and the babies. Among the many challenges in the follow-up of twin pregnancies, the mode of delivery is the last but not the least decision to be made, with the main influencing factors being amnionicity and fetal presentation. The aim of the study was to compare perinatal outcomes in two European centers using different protocols for twin birth in case of non-cephalic second twin; the Italian patients being delivered mainly by cesarean section with those in Belgium being routinely offered the choice of vaginal delivery (VD). METHODS: This was a dual center international retrospective observational study. The population included 843 women with a twin pregnancy ≥ 32 weeks (dichorionic or monochorionic diamniotic pregnancies) and a known pregnancy outcome. The population was stratified according to chorionicity. Demographic and pregnancy data were reported per pregnancy, whereas neonatal outcomes were reported per fetus. We used multiple logistic regression models to adjust for possible confounding variables and to compute the adjusted odds ratio (adjOR) for each maternal or neonatal outcome. RESULTS: The observed rate of cesarean delivery was significantly higher in the Italian cohort: 85% for dichorionic pregnancies and 94.4% for the monochorionic vs 45.2% and 54.4% respectively in the Belgian center (p-value < 0.001). We found that Belgian cohort showed significantly higher rates of NICU admission, respiratory distress at birth and Apgar score of < 7 after 5 min. Despite these differences, the composite severe adverse outcome was similar between the two groups. CONCLUSION: In this study, neither the presentation of the second twin nor the chorionicity affected maternal and severe neonatal outcomes, regardless of the mode of delivery in two tertiary care centers, but VD was associated to a poorer short-term neonatal outcome.

Impact of perinatal factors on meconium aspiration syndrome in full-term newborns and the construction of a column chart prediction model: An observational study.

To explore the influence of perinatal-related factors on meconium aspiration syndrome (MAS) in full-term neonates and construct a nomogram prediction model for risk stratification of neonatal MAS and adoption of preventive measures. A total of 424 newborns and their mothers who were regularly examined at our hospital between January 2020 and December 2023 who had meconium-contaminated amniotic fluid during delivery were retrospectively selected as participants. Neonates were divided into MAS and non-MAS groups based on whether MAS occurred within 3 days after birth. Data from the 2 groups were analyzed, and factors influencing MAS were screened using multivariate logistic regression analysis. The R3.4.3 software was used to construct a nomogram prediction model for neonatal MAS risk. Receiver operating characteristic (ROC) curve analysis and the Hosmer-Lemeshow goodness-of-fit test were used to evaluate the performance of the model, and its clinical effectiveness was evaluated using a decision curve. Among the 424 neonates with meconium-stained amniotic fluid, 51 developed MAS within 3 days of birth (12.03%). Multivariate logistic regression analysis showed that a low amniotic fluid index before delivery (OR = 2.862, P = .019), advanced gestational age (OR = 0.526, P = .034), cesarean section (OR = 2.650, P = .013), severe amniotic fluid contamination (OR = 4.199, P = .002), low umbilical cord blood pH (OR = 2.938, P = .011), and low neonatal Apgar 1-min score (OR = 3.133, P = .006) were influencing factors of MAS in full-term neonates. Based on the above indicators, a nomogram prediction model for MAS risk of full-term newborns was constructed. The area under the ROC curve of the model was 0.931. The model was also tested for goodness-of-fit deviation (χ2 = 3.465, P = .903). Decision curve analysis found that the model was clinically effective in predicting the net benefit of MAS risk in neonates with meconium-stained amniotic fluid. The construction of a column chart prediction model for neonatal MAS risk based on prenatal amniotic fluid index, gestational age, delivery method, amniotic fluid contamination level, newborn umbilical blood pH value, and Apgar 1-min score has a certain application value.

The association between attention deficit hyperactivity disorder and pregnancy, delivery and neonatal outcomes-an evaluation of a population database.

BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is one of the more common neuropsychiatric disorders in women of reproductive age. Our objective was to compare perinatal outcomes between women with an ADHD diagnosis and those without. METHODS: A retrospective population-based cohort study utilizing the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS) United States database. The study included all women who either delivered or experienced maternal death from 2004 to 2014. Perinatal outcomes were compared between women with an ICD-9 diagnosis of ADHD and those without. RESULTS: Overall, 9,096,788 women met the inclusion criteria. Amongst them, 10,031 women had a diagnosis of ADHD. Women with ADHD, compared to those without, were more likely to be younger than 25 years of age; white; to smoke tobacco during pregnancy; to use illicit drugs; and to suffer from chronic hypertension, thyroid disorders, and obesity (p < 0.001 for all). Women in the ADHD group, compared to those without, had a higher rate of hypertensive disorders of pregnancy (HDP) (aOR 1.36, 95% CI 1.28-1.45, p < 0.001), cesarean delivery (aOR 1.19, 95% CI 1.13-1.25, p < 0.001), chorioamnionitis (aOR 1.34, 95% CI 1.17-1.52, p < 0.001), and maternal infection (aOR 1.33, 95% CI 1.19-1.5, p < 0.001). Regarding neonatal outcomes, patients with ADHD, compared to those without, had a higher rate of small-for-gestational-age neonate (SGA) (aOR 1.3, 95% CI 1.17-1.43, p < 0.001), and congenital anomalies (aOR 2.77, 95% CI 2.36-3.26, p < 0.001). CONCLUSION: Women with a diagnosis of ADHD had a higher incidence of a myriad of maternal and neonatal complications, including cesarean delivery, HDP, and SGA neonates.

The association between increased fetal movements in the third trimester and perinatal outcomes; a systematic review and meta-analysis.

BACKGROUND: Fetal movement monitoring is one of the strategies used to assess the fetus's health. Until now, most studies focused on the decreased fetal movement and neonatal outcome, although this systematic review and meta-analysis is designed to assess the association between increased fetal movements (IFM) with perinatal outcomes. METHOD: The electronic databases including PubMed, Scopus, Web of Science, and EMBASE were systematically searched for studies investigating the perinatal outcome of women with increased fetal movements from inception to July 2023. Following that, a random-effect meta-analysis model was used to obtain the combined diagnostic and predictive parameters including perinatal mortality (still birth and early neonatal mortality), operative delivery, Apgar score, neonatal resuscitation at birth and NICU Admission. RESULTS: After the initial screening, seven studies examining the association between increased third trimester fetal movement and various perinatal outcomes were included. Meta-analysis revealed a significant reduction in the risk of cesarean delivery among patients with IFM compared to controls, suggesting a potential protective effect during childbirth. However, no statistically significant difference was observed in birth weight, small or large for gestational age births, neonatal intensive care unit admission, maternal age, umbilical cord around the neck, gestational diabetes mellitus, and hypertension, indicating that IFM may not be a major predictor of adverse perinatal outcomes or maternal conditions. Notably, IFM was significantly associated with a higher likelihood of labor induction. CONCLUSION: The findings suggest that IFM may have a protective effect against cesarean delivery. Additionally, IFM does not appear to be significantly associated with maternal age, umbilical cord around the neck, gestational diabetes mellitus and hypertension. However, the observed significant association with labor induction warrants further investigation.
