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..

A Validated Calculator to Estimate Risk of Chorioamnionitis in Laboring and Induced Patients at Term.

Chorioamnionitis is associated with neonatal morbidity and infection-related mortality, but our ability to predict intrapartum infection is limited. We sought to derive and validate a prediction model for chorioamnionitis among patients presenting to labor and delivery at term. This was a planned secondary analysis of a large cohort study from 2014 through 2018 at an academic tertiary care center. To derive a prediction model for chorioamnionitis, we limited our analysis to full-term (≥37 weeks) patients with a singleton gestation undergoing labor induction and presenting in labor. Both nulliparous and multiparous patients were included. Patients with a planned cesarean delivery, fever on admission, or missing data were excluded. The model was derived using multivariable logistic regression. Refinement of the prediction model with internal calibration was performed. External validation was performed utilizing a publicly available database (Consortium on Safe Labor) and applying the same inclusion and exclusion criteria. The discriminative power of each model was assessed using a bootstrap, bias-corrected area under the curve. The chorioamnionitis rates in the derivation and external validation groups were: 5% (1,005/19,966) and 5.8% (n = 3,005/52,171), respectively. In multivariable modeling, maternal age, nulliparity, gestational age, smoking status, group B streptococcus colonization, hours ruptured, number of cervical exams, length of labor, epidural use, internal monitoring, and meconium were significantly associated with infection. A calculator was created and externally validated with an area under the curve of 0.82 (95% confidence interval, 0.81-0.82). External validity was further confirmed with a calibration intercept of 0.81. This is the first infection calculator created and validated for the prediction of developing chorioamnionitis in patients undergoing induction of labor at term. This calculator can be used to augment patient counseling and guide intrapartum infection surveillance in laboring patients.

Analysis of Cesarean Section Rates Using Robson Ten Group Classification System in A Tertiary Care Hospital of Peshawar: A Cross-Sectional Study

Objective: To observe CS rates and assess them using Robson's Ten Groups Categorization System in a government tertiary medical facility in Peshawar, Pakistan Study Design and Setting: From 1st March to 31st August 2023, a cross-sectional study was carried out at the Khyber Teaching Hospital’s department of obstetrics and gynecology in Peshawar, Pakistan Methodology:. The research cohort consisted of 1250 women with CS who were hospitalized throughout the specified study period. Information on maternal features and pregnancy-related details was collected for every patient. Results: 4227 women sought labor and delivery services during the course of the research. It was discovered that the CS rate was 29.5%. Most common were Groups 1 (7.57%), 3 (8.65%), and 5 (54.66%), which together accounted for around 69% of all CS occurrences. Group 5's CS rate was 80.7%, but subgroup 5.1's (previous CS) women experienced repeat CS at a rate of 65.14%. 95% babies were alive and 5% were stillborns. Conclusion: Noticeable raise in the caesarean deliveries rate, leading to substantial worse influence in terms of health, finances, and society. Previous CS is the most prevalent sign of CS.CS if performed on primigravidae with a valid indication, the rate of CS may be managed.

A STUDY OF OBSTETRIC HYSTERECTOMY OVER A PERIOD OF 5 YEARS AT CUSMCH

Objectives: The study aimed (1) to determine the indication of obstetric hysterectomy and (2) to determine the fetomaternal outcome. Methods: This is a hospital-based retrospective study carried out in the Department of Obstetrics and Gynecology, C.U.Shah Medical College and Hospital from January 2018 to December 2020. Results: Out of 8881 deliveries during our study period, there were a total of 20 patients who underwent an obstetric hysterectomy, the incidence being 0.2%. Nine cases out of 6871 vaginal deliveries and 11 cases out of 2510 cesarean deliveries required an obstetric hysterectomy. Maximum patients, seven out of 20 were between 31 and 35 years age group followed by six patients between 36 and 40 years and five patients above 41 years. Only two patients were below 30 years of age. Most of the cases (70%) belonged to the lower middle class and 30% were from the upper middle class. About 60% were registered antenatal care (ANC) cases while 40% never visited any health-care facility. Out of 20 patients who underwent an obstetric hysterectomy, 18 patients (90%) were referred from another center while only 2 patients (10%) were admitted at our center. Eleven patients that are 55% delivered outside the institute among which three patients were home delivered by unskilled birth attendants. Nine patients were delivered at our center and among these sseven patients were referred from adjoining primary health-care centers, community health-care centers, and other private hospitals. Our institute being a tertiary hospital, maximum high-risk and complicated deliveries were referred. Conclusion: Obstetric hysterectomy is an unwanted but necessary emergency in obstetrics. It is a life-saving procedure in many catastrophic conditions, although it curtails the future. Good ANC, identification of risk factors, timely referral, and intervention at a well-equipped hospital can reduce obstetric hysterectomies. With the increasing incidence of cesarean deliveries and morbidly adherent placenta, the need for obstetric hysterectomy is increasing. With the improvement of modern obstetrics and modern modalities for the treatment of postpartum hemorrhage and adherent placenta, there is a reduction in the number of obstetric hysterectomies.

CESAREAN AUDIT: USING ROBSON’S 10 GROUP CLASSIFICATION AT C. U. SHAH MEDICAL COLLEGE AND HOSPITAL

Objective: The World Health Organization (WHO) has expressed concern over the rising cesarean section (CS) rate, particularly in middle-and high- income countries. The reasons behind this increase are still debated, but the WHO declared that there is no justification for a rate higher than 10–15%. The Robson classification system, advocated by WHO and FIGO, can help assess and compare CS rates. Study Design and Methods: The Gynecology Department at C.U. Shah Medical College and Hospital conducted an observational study on pregnant patients hospitalized for labor pain between January 2020 and December 2022, with a focus on CS patients. The study used Robson’s 10-group categorization technique to extract maternal features and categorize cesarean performances. Results: Between January 2020 and December 2022, C. U. Shah Medical College and Hospital delivered 4967 patients, of whom 1,572 underwent a CS section. 46.3% were nulliparous, and 53.7% were multipara. 78.31% of patients arrived at full term, with 98.8% having single conceptions. 94.8% of the cases had a cephalic presentation, 4.4% had a breech presentation, and 0.81% had a transverse position. Conclusions: Robson classification is a useful technique for analyzing cesarean delivery (CS) rates, aiding in identifying corrective methods to reduce burden on healthcare systems, and promoting accurate labor monitoring, fetal scalp electrodes, and prenatal education.

Evaluation of the Effect of Vaginal Delivery on Stress Urinary Incontinence and Bladder Neck Mobility with Transperineal Ultrasonography

Aim: Stress urinary incontinence is a common and distressing situation in females, impacting emotional and psychological well-being by interrupting sexual, physical, and social forms of life. Perineal trauma, especially at childbirth, is one of the most common contributing factors. The objective of this research is assessing the impact of vaginal delivery, a factor known to elevate the likelihood of postpartum stressxincontinence, on bladder neck mobility. This evaluation will be conducted utilizing transperinealxultrasonography, a noninvasivexand well-toleratedxdiagnostic technique. Materials and Methods: In our study, 116 patients who gave birth in our hospital between January 2020 and May 2022 were evaluated retrospectively. The presence of stress urinary incontinence and transperineal ultrasonography data of all patients were examined from the patient files. To evaluate changes in bladder neck motility, ultrasound measurements made both prenatally and postnatally were evaluated retrospectively. Results: With regard to the demographic values of the patients, a statistically significant difference was seen in terms of the presence of urinary incontinence when multiparous and primiparous patients were compared with patients in the cesarean section group (p:0.01). There was a significant difference in ΔDx, ΔDy, and M values for the cesarean delivery group as compared to both the primiparous and multiparous vaginal delivery groups (p

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.

12503 An Observational Study Of The Glycemic Variability In Type 1 Diabetes Mellitus Women Preconception And During Pregnancy And Its Associations With Adverse Maternal And Neonatal Outcomes

Abstract Disclosure: S. Avula: None. A.R. Ankireddypalli: None. K. Tessier: None. E.R. Seaquist: None. Background: Pregnancy in T1 diabetes mellitus (T1DM) women is associated with increased risk of maternal/fetal complications. Despite glycemic optimization during pregnancy in T1DM, offspring are at increased risk for neonatal complications. Aim: To examine glycemic variability by continuous glucose monitor (CGM) preconception and during pregnancy by trimester and assess the association with adverse maternal/fetal outcomes. Methods: This was a retrospective cohort study of pregnant patients with T1DM who used real-time CGM and delivered at a U.S. tertiary center (2012-2023). Multiple gestations, Cystic fibrosis-related diabetes (CFRD), twin or multiple births, and no valid CGM data for at least one trimester were excluded. 63 met the inclusion criteria. The primary outcome was composite neonatal morbidity (CNM), including large or small for gestational age (LGA/SGA), NICU admission, neonatal hypoglycemia, shoulder dystocia, respiratory distress syndrome, APGAR 1 or 5 minutes < 7, prematurity (<37 weeks), intrauterine growth restriction (IUGR), CPAP, and ventilator. We also collected data about maternal outcomes. Results:54 patients (86%) met at least one outcome included in the CNM. 20 patients (32%) were LGA, 3 (5%) were SGA, 32 (51%) premature, 29 (46%) required NICU admission, 44 (70%) had neonatal hypoglycemia, 3 (5%) had shoulder dystocia, 23 (37%) had respiratory distress, 22 (35%) needed CPAP, 3 (5%) were on ventilator, 11 (18%) had APGAR 1 minute <7. Among maternal outcomes, 18 (29%) developed pre-eclampsia, and 46 (73%) had a cesarean delivery. Overall, individuals with neonatal morbidity had a lower target in range (TIR) and higher target above range(TAR), average glucose, standard deviation(SD), and coefficient of variation (CV) compared with those without the primary composite, but statistical significance was seen for average glucose and TAR. For every 5 mg/dl increase in average glucose (mean of the 3-trimester values), there was a 25% increase in odds of neonatal morbidity (OR 1.25; 95% CI 1.04-1.56; p=0.028). There was a significant association between 1st trimester SD and neonatal morbidity (OR 1.11; 95% CI 1.02-1.24; p=0.027). There was a trend toward significance between the 3rd-trimester average blood glucose and neonatal morbidity (OR 1.26; 95% CI 1.02-1.63; p=0.051). Conclusion: In our single-center cohort, we found maternal average glucose and TAR, as well as first trimester SD, were significantly associated with CNM. This confirms that maternal hyperglycemia and demonstrates that first trimester SD are associated with poorer neonatal outcomes. Presentation: 6/1/2024

7833 Gestational Diabetes Mellitus (GDM): A Weighted Spectrum of Clinical Outcomes

Abstract Disclosure: M. Moazzami: None. N. Venkatesan: None. K.S. Rajagopalan: None. A.V. Vella: None. A. Egan: None. Gestational diabetes mellitus (GDM) affects approximately 10% of pregnancies, with rates almost doubling in minority subgroups. Higher body mass index (BMI) is a significant GDM risk factor, and BMI ≥ 25kg/m2 is often used as a criterion in risk factor-based screening programs. However, up to 60% of individuals with GDM have a normal BMI, and it is unclear if this offers protection against associated adverse outcomes. Furthermore, many prior studies fail to address the fact that those of Asian descent require a lower BMI cut-off, given their different distribution of body fat. Our study evaluated GDM pregnancy outcomes using BMI as a risk indicator. We compared individuals with BMIs < 25 kg/m2, 25-30 kg/m2, and > 30 kg/m2. For individuals that self-identified as Asian, we adjusted BMI categories: <23 kg/m2 for normal weight, 23-30 kg/m2 for overweight, and >30 kg/m2 for obese. We identified 2212 subjects diagnosed with GDM via universal screening and Carpenter and Coustan criteria at our institution from 2018 - 22. In total, 508 (23.0%) were normal weight, 611 (27.6%) overweight, and 1093 (49.4%) obese. The average maternal age was 31 years. Higher proportions identified as Hispanic and non-White race in overweight and obese categories. Maternal adverse outcomes were higher in obese compared to overweight or normal BMI categories (cesarian delivery: normal 26.7 v overweight 28.3 v obese 22.7%, p<0.001; hypertensive disorders: normal 13.2 v overweight 12.5 v obese 22.7%, p <0.001). Pharmacological therapy was required in 50% with obesity versus 24.8% in normal, and 28.7% in overweight categories (p<0.001). While there were no differences in live birth rates across categories, infants born to mothers with obesity had a higher birthweight (normal 3.30 v overweight 3.38 v obese 3.45kg, p<0.001) and were more likely to have neonatal hypoglycemia (normal 28.7 v overweight 25.5 v obese 43.8%, p<0.001) and require intensive care unit admission (normal 8.4 v overweight 5.5 v obese 12.7%, p<0.001). Attendance at postpartum glucose testing varied across BMI categories with lower attendance in mothers with obesity followed by normal weight BMI (normal 40.75 v overweight 45.99 v obese 36.2%, p<0.001). Compared to overweight individuals, those with normal weight exhibited higher rates of postpartum glucose intolerance (12.4 v 6.9%, p =0.002). However, those with obesity had the highest rates of glucose intolerance (20.7%, p<0.0002). Individuals with normal weight had the highest rates of breastfeeding (normal 95.9 v overweight 92.8 v obese 91.4% p=0.006). This study highlights the nuanced relationship between BMI and pregnancy outcomes in GDM. While maternal obesity was associated with the poorest outcomes, those with normal BMI were not protected compared to overweight individuals, and experience higher rates of postpartum glucose intolerance.

6823 A Puzzling Case: Complete Regression of Pituitary Macroadenoma

Abstract Disclosure: N.T. Mazengia: None. D.R. Vangipuram: None. S.K. Majumdar: None. Introduction: The natural course of nonfunctioning pituitary macroadenomas remains poorly understood, largely because the majority are surgically treated [1]. There are a few case reports describing the spontaneous regression of nonfunctioning pituitary macroadenomas. Here we describe a case of pituitary macroadenoma which completely regressed following childbirth and two months of cabergoline therapy. Case Presentation: A 25-year-old female presented with bilateral nipple discharge and persistently elevated prolactin levels ranging from 31µg/liter to 45.9 µg/liter (NV <25 µg/L). She did not have any signs and symptoms of hypo or hypersecretion of the pituitary hormones. All her pituitary hormone levels were within normal range. Initial MRI revealed a pituitary mass measuring 9x13x9mm (AP, TR, CC). Given her lack of symptoms, the decision was made to follow up without any intervention. A repeat MRI after one year showed the size of the mass to be 11x13x11mm. Two years after her initial diagnosis, the patient had a spontaneous pregnancy, during which she remained asymptomatic with normal pituitary hormone levels. She had Cesarean delivery at term with no complication. She was lost to follow-up for about two years after childbirth then presented with breast discomfort and galactorrhea at which time, she was started on cabergoline. A subsequent MRI done two months after the start of cabergoline showed asymmetric fullness of the pituitary gland on the right with no discrete measurable lesion. Conclusion: We currently lack a comprehensive explanation for the regression observed in our patient. Silent ischemia may have played a role, particularly considering the natural increase in pituitary gland size during pregnancy. We are not sure if the regression can be solely attributed to the two months of cabergoline treatment. In asymptomatic patients diagnosed with nonfunctioning pituitary macroadenoma, tumor regression can potentially occur through either a "wait and watch" strategy or medical management using dopamine agonists, specifically cabergoline. However, the use of cabergoline as a primary treatment for asymptomatic nonfunctioning pituitary adenoma warrants further investigation. This is especially crucial given that, in most cases, nonfunctioning pituitary macroadenomas tend to increase in size during follow-up without any intervention.

MiniMizer Gastric Ring displacement at 31 weeks of gestation as a life-threatening complication

This case report describes a pregnant woman who underwent a laparoscopic MiniMizer Gastric Ring procedure for clinically severe obesity only one month before conception. At 31 weeks of gestation, the patient as admitted to the hospital with postprandial vomiting and persistent left-sided colicky abdominal pain. Maternal abdominal MRI revealed an intestinal obstruction and elective surgery was recommended. Due to the considerable risk to the fetus, antenatal corticosteroids were immediately administered to promote lung maturation and magnesium sulfate was started for fetal neuroprotection. During an exploratory laparoscopy, significantly enlarged and ischemic intestinal loops were found, leading to the decision to perform an atraumatic “en caul” cesarean delivery. After a successful “en caul” delivery, the MiniMizer ring, which had dislodged downwards and led to mesenteric ischemia, was visualized. Intraoperative esophagogastroduodenoscopy revealed a 1cm defect in the stomach wall related to gastric ring, covered with purulent exudate. Further exploration, showed a herniation of the distal alimentary loop through the Petersen foramen. Successful management included ring removal and intestinal loop reduction from the Petersen’s space, without evidence of strangulation, as confirmed with indocyanine green (ICG) angiography. The postoperative course was uneventful. Women with obesity who have undergone bariatric surgery should to be informed of the increased likelihood of becoming pregnant after treatment. It is advised to notify the patient of the importance of maintaining a sufficient interval between bariatric surgery and conception. Additionally reports from the literature on various complications during pregnancy after bariatric surgery are presented.

6900 Fetal Abdominal Obesity in Women Exhibiting One Abnormal Value on Diagnostic Testing for Gestational Diabetes Mellitus

Abstract Disclosure: W. Kim: None. S. Park: None. Y. Kim: None. Background: Fetal abdominal obesity (FAO) was already observed at the time of diagnosis of GDM in our previous study. We investigated whether fetuses of women with hyperglycemia milder than GDM showed accelerated abdominal growth, leading to adverse pregnancy outcomes. Methods: We retrospectively reviewed the medical records of 7,569 singleton pregnant women who were universally screened using a 50-g glucose challenge test (GCT) and underwent a 3-h 100-g oral glucose tolerance test (OGTT) if GCT result was ≥140mg/dL. GDM, one value abnormality (OVA), and normal glucose tolerance (NGT, NGT1: GCT negative, NGT2: GCT positive & OGTT negative) were diagnosed using Carpenter-Coustan criteria. With fetal biometry data measured simultaneously with 50-g GCT, relative fetal abdominal overgrowth was investigated by assessing the fetal abdominal overgrowth ratios (FAORs) of the ultrasonographically estimated gestational age (GA) of abdominal circumference(AC) per actual GA by the last menstruation period(LMP), biparietal diameter (BPD) or femur length(FL), respectively. FAO was defined as FAOR ≥90th percentile Results: The FAORs of GA-AC/GA-LMP and GA-AC/GA-BPD were significantly higher in OVA subjects compared to NGT subjects but not in NGT2 subjects. Although the frequency of FAO in OVA (12.1%) was between that of NGT (9.6%) and GDM (18.3%) without statistically significant difference, the prevalence of large for gestational age at birth and primary cesarean delivery rates were significantly higher in OVA (9.8% and 29.7%) than in NGT (5.1% and 21.5%, p<0.05). Particularly, among OVA subjects with FAO, the prevalence (33.3% and 66.7%) was significantly higher than in those without FAO (9.7% and 24.2%, p<0.05). Conclusion: The degree of fetal abdominal growth acceleration in OVA subjects was intermediate between that of NGT and GDM subjects. OVA subjects with FAO at the time of GDM diagnosis were strongly associated with adverse pregnancy outcomes. Presentation: 6/2/2024

Twin pregnancy and postpartum haemorrhage: a systematic review and meta-analysis

BackgroundPostpartum haemorrhage (PPH) continues to stand as the primary cause of maternal morbidity and mortality post-delivery, with twin pregnancies carrying a heightened risk of PPH compared to singleton deliveries.ObjectivesTo investigate the incidence of primary PPH among twin pregnancies and report on maternal and peripartum characteristics within this population.MethodsA literature search was conducted using data from PubMed, EMBASE, Cochrane, Scopus, and Web of Science. The search aimed to identify studies concerning mothers with twin pregnancies and postpartum haemorrhage (PPH) from the inception of each respective database to June 8th, 2023. Pooled means and proportions were analyzed using the generic inverse variance method. This review was registered prospectively with PROSPERO (CRD42023427192).ResultsA total of 21 studies involving 23,330 twin pregnant patients were included. Incidence of PPH for vaginal delivery and Caesarean delivery (CS) was found to be 10.9% (95% CI: -0.017, 0.235, I2 = 96%) and 27.0% (95% CI: 0.180, 0.359, I2 = 99%) respectively. In vitro fertilization (IVF) was the most common conception method at 62.0% (95% CI: 0.448, 0.792, I2 = 100%) with 81.1% (95% CI: 0.708, 0.915, I2 = 100%) of twins being dichorionic diamniotic.ConclusionThis meta-analysis demonstrated more than one in ten vaginal deliveries and over one in four cesarean sections result in PPH for twin pregnancies. IVF is the predominant method of conception in this patient group and seems to contribute to subsequent PPH risk in specific mothers. While preliminary, these findings underscore the necessity for further well-designed and high-quality studies to validate these results.

Neonatal Bilirubin Assessment After Implementation of Enhanced Recovery After Caesarean Section

Objective: The implementation of Enhanced Recovery After Cesarean (ERAC) is associated with significant improvement in maternal outcomes; however, its impact on neonatal outcomes remains limited. This study aims to evaluate the impact of ERAC protocol on neonatal outcomes. Methods: A retrospective cross-sectional study was conducted at Bunda Women and Children Hospital, Jakarta, Indonesia between 2021 and 2022 on women who performed cesarean delivery at 37 weeks and above. The primary outcome was neonatal bilirubin level and the secondary outcome was neonatal length of stay and breastfeeding rate. Results: Differences between outcomes were analyzed by comparing each parameter in non-ERAC (n = 356) and the ERAC groups (n = 331). The median bilirubin levels and neonatal length of stay did not exhibit significant differences between the non-ERAC and the ERAC group (9.5 mg/dL vs 9.5 mg/dL, P = .545, for bilirubin levels, and 3 days vs 3 days, P = .060 for neonatal length of stay). However, the ERAC group demonstrated a significantly higher breastfeeding rate compared to the non-ERAC group (3 hours vs 5 hours, P < .001, respectively). Conclusions: The implementation of the ERAC protocol does not influence neonatal bilirubin levels and the length of neonatal hospital stays but it increases breastfeeding rate.

Bioequivalence and pharmacokinetics of intravenous calcium during cesarean delivery.

Few studies have assessed the dose ratio of calcium gluconate to calcium chloride or defined the time course of change in serum ionized calcium concentration after intravenous injection. In a bioequivalence (dose ratio) trial, parturients undergoing cesarean delivery were randomly assigned to receive calcium chloride 0.5 grams or calcium gluconate 1.5 or 2 grams by 10-minute intravenous infusion. Venous serum ionized calcium concentration was measured prior to calcium infusion and approximately 5, 10, 15, 30, and 60 minutes after infusion start. We combined these data with serum ionized calcium concentration measurements in parturients who received 1 gram calcium chloride or saline placebo in two recent clinical trials to define the pharmacokinetics of intravenous calcium over the first hour during and after drug administration. The bioequivalence study enrolled 34 participants, from whom we collected 181 serum ionized calcium concentration measurements. The dose ratio of calcium gluconate to calcium chloride was 3.11 (95% CI: 2.77-3.48). Population pharmacokinetics of calcium were determined using 311 serum ionized calcium concentration measurements from 70 parturients. The pharmacokinetics of intravenous calcium were described by a two-compartment model with systemic clearance of 0.18 (95% CI: 0.07-0.27) L/min, distributional clearance of 1.25 (95%CI: 1.03-1.56) L/min, central volume of 10.9 (95% CI: 9.3-12.6) L, and peripheral volume of 16.5 (95% CI: 12.5-24.7) L. After adjusting for the dose ratio, calcium gluconate and calcium chloride had identical time courses. A one-gram infusion of calcium chloride results in a peak increase in serum ionized calcium concentration of 0.39 (0.38-0.42 mmol/L), which decreases by half 29 (23-40) minutes after initiation of the 10-minute infusion. We confirmed a 3:1 dose ratio of calcium gluconate to calcium chloride and estimated the pharmacokinetics over the first hour following intravenous delivery. These data inform clinical care and may guide future trials assessing calcium efficacy to reduce bleeding in obstetric patients. NCT05973747 (bioequivalence), NCT05027048, and NCT03867383 (trials included in pharmacokinetic assessment).

EVALUATING PERINATAL OUTCOMES IN HIGH-RISK PREGNANCIES USING THE MODIFIED COOPLAND’S SCORING SYSTEM AT A TERTIARY HOSPITAL

This study aims to thoroughly assess perinatal mortality rates, Apgar scores, birth weights, and neonatal complications within the first-week post-birth among high-risk pregnancies. Methods: During a prospective cohort study at Jinnah Postgraduate Medical Centre, Karachi, from October 2023 to May 2024, we evaluated outcomes in 664 high-risk pregnant women using systematic random sampling. Participants, with singleton pregnancies of 24 weeks or more gestation, were stratified by risk level. Data included demographic details, socioeconomic status, BMI, and pregnancy history. Maternal outcomes, such as mode of delivery and postpartum haemorrhage requiring transfusion, and perinatal outcomes, including birth weight and APGAR scores, were assessed. Statistical analysis emphasized odds ratios, with p < 0.05 considered significant. Ethical approval was obtained, and all participants provided informed consent. Results: This prospective cohort study at Jinnah Postgraduate Medical Centre from October 2023 to May 2024 involved 664 high-risk pregnant women categorized by standard risk scoring. Participants were predominantly low-risk (65.77%), followed by moderate-risk (19.88%) and high-risk (14.35%). Key findings included increased rates of cesarean sections, postpartum haemorrhage, premature births, low birth weight, adverse APGAR scores, NICU admissions, and perinatal mortality with escalating risk levels. Statistical analyses revealed significant associations and elevated odds ratios for adverse outcomes among higher-risk groups, underscoring the importance of risk assessment in managing maternal and perinatal health outcomes. Conclusion: Our study highlights the urgent importance of identifying and effectively managing high-risk pregnancies. We discovered that these pregnancies are associated with significantly elevated risks of complications such as Cesarean deliveries, postpartum haemorrhage, preterm births, low birth weights, low 5-minute APGAR scores, NICU admissions, and perinatal mortality. Implementing a straightforward, non-invasive risk-scoring system can facilitate early detection of high-risk cases, enabling timely and tailored interventions that can greatly improve outcomes for both mothers and infants.

Obstetric and neonatal outcomes in women with Ankylosing spondylitis - an evaluation of a population database

BackgroundAnkylosing Spondylitis (AS) is a systemic chronic rheumatic disease characterized by involvement of the axial skeletal and sacroiliac joints. Although this disease is not rare amongst women of reproductive age, data regarding pregnancy outcomes have demonstrated conflicting results. We therefore aimed to compare pregnancy and perinatal outcomes between women who suffered from AS to those who did not.MethodsA retrospective cohort study using the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS). Included in the study were all pregnant women who delivered or had a maternal death in the US between 2004 and 2014. Women with an ICD-9 diagnosis of AS before or during pregnancy were compared to those without. Pregnancy, delivery, and neonatal outcomes were compared between the two groups using multivariate logistic regression models adjusting for potential confounders.ResultsA total of 9,096,788 women were inclusion in the analysis. Amongst them, 383 women (3.8/100,000) had a diagnosis of AS and the rest were controls. Women with AS, compared to those without, were more likely to be older; Caucasian; from higher income quartiles; suffer from thyroid disorders, and have multiple pregnancies (p < 0.001, all). After adjusting for confounders, patients in the AS group, compared to those without, had a higher rate of cesarean delivery (CD) (aOR 1.47, 95% CI 1.14–1.91, p = 0.003); gestational diabetes (aOR 1.55, 95% CI 1.02–2.33, p = 0.038); and placenta previa (aOR 3.6, 95% CI 1.6–8.12, p = 0.002). Regarding neonatal outcomes, patients with AS, compared to those without, had a higher rate of small-for-gestational-age (SGA) neonates (aOR 2.19, 95% CI 1.22–3.93, p = 0.009); and intrauterine fetal death (IUFD) (aOR 3.46, 95% CI 1.11–10.83, p = 0.033).ConclusionWomen diagnosed with AS have an increased risk of obstetric complications, including CD, as well as an increased risk of SGA and IUFD.

How two-child policy affects cesarean section in women with advanced maternal age (AMA): using the Robson classification system

ObjectivesTo study the possible associations between advanced maternal age and cesarean section(CS) under the two child policy.MethodsThis study used a cohort study from Dongguan People’s Hospital in Guangdong Province, China from 2017 to 2020. The cohort was restricted to women aged ≥ 20 who give birth to babies with a gestational age of > 28 weeks and a weight of > 1000 g. Divide the advanced maternal age (AMA) pregnant women into two age groups: 35–39 years old and 40 years old or older age. We analyzed CS rate and CS contribution using the modified Robson classification system. Frequency of cesarean was determined for each group and compared by using χ2 and prevalence ratio.ResultsOverall, 47654 women were included, of which 7924 (16.63%) were between the ages of 35 and 39, and 1529 (3.21%) were aged 40 or older. The total CS rate is 40.64%, with 36.10% for mothers aged 20 to 34, 57.90% for women aged 35 to 40, and 64.75% for women aged 40 or older age. In the AMA groups (n = 9453), Robson group 2’ was the most common, followed by groups 5 and 10. Women at 40 years or older age were 3 times more likely to undergo a cesarean delivery in Robson group 1’, and 1.76 times more likely in group 10. The CS rate in group 2’ were statistically significantly higher in the very AMA group.ConclusionsThe CS rates increased noticeably with maternal age under the two child policy. Based on the modified Robson classification system, AMA women should pay more attention to primiparous women with single pregnancy, uterine scars, and premature birth in multiple pregnancies.

Antenatal maternal serum biomarkers as a predictor for placenta accreta spectrum disorders

IntroductionPlacenta accreta spectrum (PAS) disorder, an abnormal adherence of the placenta to the uterine wall, with variable degrees of invasion, is a major cause of maternal morbidity and mortality associated with severe postpartum hemorrhage. PAS is diagnosed using ultrasonography or with magnetic resonance imaging; in many centers there is a lack of PAS diagnostic expertise in diagnosing. Hence, we investigated the performance of selected maternal plasma protein biomarkers, antithrombin-III (AT-3), plasminogen activator inhibitor-I (PAI-I), soluble vascular endothelial growth factor receptor-II (sVEGFR-2), and soluble Tie-II (sT-2) for prenatal screening in pregnancies at a high risk of PAS. MethodsThis prospective study, conducted in a tertiary hospital from September 2021 to May 2022, included pregnant women with placenta previa suspicious of PAS between 28 and 42 weeks of gestation. Four serum samples were collected from each woman to evaluate serum concentrations and compared between placenta previa (control) and PAS groups. The screening performances of the biomarkers were analyzed, and the best screening model for PAS was created. ResultsTwenty-two women with PAS and 18 with placenta previa alone were included (n = 40). The median concentrations of PAI-I, AT-3, sVEGFR-2, and sT-2 among the PAS group were 21.2, 6154.6, 7.5, and 12.8 ng/mL, respectively. The best screening model for PAS combined all four biomarkers with a history of cesarean delivery (77 % sensitivity, 89 % specificity, and an AUC of 0.87). DiscussionA combination of the four maternal serum biomarkers in women with a history of cesarean delivery presented the most promising model for prenatal screening of PAS. ConclusionA combination of the four maternal serum biomarkers with a history of cesarean delivery presented the most promising model for prenatal screening of PAS.
