Association between plasma leptin and cesarean section after induction of labor: a case control study

Background Obesity in pregnancy is common, with more than 50% of pregnant women being overweight or obese. Obesity has been identified as an independent predictor of dysfunctional labor and is associated with increased risk of failed induction of labor resulting in cesarean section. Leptin, an adipokine, is secreted from adipose tissue under the control of the obesity gene. Concentrations of leptin increase with increasing percent body fat due to elevated leptin production from the adipose tissue of obese individuals. Interestingly, the placenta is also a major source of leptin production during pregnancy. Leptin has regulatory effects on neuronal tissue, vascular smooth muscle, and nonvascular smooth muscle systems. It has also been demonstrated that leptin has an inhibitory effect on myometrial contractility with both intensity and frequency of contractions decreased. These findings suggest that leptin may play an important role in dysfunctional labor and be associated with the outcome of induction of labor at term. Our aim is to determine whether maternal plasma leptin concentration is indicative of the outcome of induction of labor at term. We hypothesize that elevated maternal plasma leptin levels are associated with a failed term induction of labor resulting in a cesarean delivery. Methods In this case-control study, leptin was measured in 3rd trimester plasma samples. To analyze labor outcomes, 174 women were selected based on having undergone an induction of labor (IOL), (115 women with successful IOL and 59 women with a failed IOL). Plasma samples and clinical information were obtained from the UI Maternal Fetal Tissue Bank (IRB# 200910784). Maternal plasma leptin and total protein concentrations were measured using commercially available assays. Bivariate analyses and logistic regression models were constructed using regression identified clinically significant confounding variables. All variables were tested at significance level of 0.05. Results Women with failed IOL had higher maternal plasma leptin values (0.5 vs 0.3 pg, P = 0.01). These women were more likely to have obesity (mean BMI 32 vs 27 kg/m2, P = 0.0002) as well as require multiple induction methods (93% vs 73%, p = 0.008). Logistic regression showed Bishop score (OR 1.5, p < 0.001), BMI (OR 0.92, P < 0.001), preeclampsia (OR 0.12, P = 0.010), use of multiple methods of induction (OR 0.22, P = 0.008) and leptin (OR 0.42, P = 0.017) were significantly associated with IOL outcome. Specifically, after controlling for BMI, Bishop Score, and preeclampsia, leptin was still predictive of a failed IOL with an odds ratio of 0.47 (P = 0.046). Finally, using leptin as a predictor for fetal outcomes, leptin was also associated with of fetal intolerance of labor, with an odds ratio of 2.3 (P = 0.027). This association remained but failed to meet statistical significance when controlling for successful (IOL) (OR 1.5, P = 0.50). Conclusions Maternal plasma leptin may be a useful tool for determining which women are likely to have a failed induction of labor and for counseling women about undertaking an induction of labor versus proceeding with cesarean delivery.

Proportion and Outcome of Induction of Labor Among Mothers Who Delivered in Teaching Hospital, Southwest Ethiopia

Background: Despite the induction of labor (IOL) having had some undesired consequences, it also has several benefits for maternal and perinatal outcomes. This study aimed to assess the proportion and outcome of IOL among mothers who delivered in Teaching Hospital, southwest Ethiopia.Methods: A retrospective cross-sectional study was conducted from June 10 to June 20, 2019, among 294 mothers who gave birth between November 30, 2018, and May 30, 2019, by reviewing their cards using a structured checklist to assess the prevalence, outcome, and consequences of induction of labor. A binary logistic regression analysis was computed to look for the association between outcome variables and independent variables.Results: The prevalence of labor induction was 20.4%. The most commonly reported cause of induction was preeclampsia (41.6%). The factors associated with IOL were mothers aged 25–34 years [AOR = 2.55, 95% CI (1.18–5.50)] and ≥35 years [AOR = 10.6, 95% CI (4.20–26.9)], having no history of antenatal care [AOR = 2.12, 95% CI (1.10–4.07)], and being Primipara AOR = 2.33, 95% CI (1.18–3.24)]. Of the 60 induced mothers, 23.3% had failed induction. The proportion of mothers with dead fetal outcomes and maternal complications was 5 and 41.7%, respectively. The unfavorable Bishop Score before induction [AOR = 1.85, 95% CI (1.32–4.87)] and induction using misoprostol [AOR = 1.48, 95% CI (1.24–5.23)] were the factors associated with failed induction of labor.Conclusion: The prevalence of induced labor was considerably higher than rates in other Ethiopian studies; however, the prevalence of induction failure was comparable to other studies done in Ethiopia. The study found that Bishop's unfavorable score before induction and induction using misoprostol was the factor associated with unsuccessful induction. Therefore, the health professionals should confirm the favorability of the cervical status before the IOL to increase the success rate of induction of labor.

Failed induction of labour and associated factors among women delivered in Jigjiga University Sheik Hassan Yabare Referral Hospital: a cross-sectional study

Introduction: Induction of labour is one component of comprehensive obstetrics care services that is increasing employed in modern day obstetrics to decrease the risk of maternal and neonatal morbidity and mortality. However, it has been strongly associated with poor maternal and perinatal outcomes. Therefore, his study was aimed to assess the magnitude of failed induction of labour and associated factors among mothers delivered at Jigjiga University Sheik Hassan Yabare referral Hospital, Eastern Ethiopia from June 1 to June 30, 2021.Methods: An institutional based cross-sectional study was carried out among 364 women’s delivered at Jigjiga University Sheik Hassan Yabare Referral Hospital from 2018 to 2021. A checklist was used to collect the data from the women’s chart. To isolate independent predictors related to failed induction of labour, multivariate logistic regression analyses were performed.Result: Our study participants were 364 women’s. The magnitude of failed induction of labour was 36.8% (95% CI: 31.8, 42.0). Age of the mother (<30 years) (AOR= 3.2; CI: 1.78, 5.75), rural residency (AOR=2.28; CI:1.29, 4.01), being primi-para (AOR= 2.76; CI: 1.55, 4.91), gestational age less than 37 or greater than 42 year (AOR= 2.65; CI: 1.44, 4.89) , multiple ton of pregnancy (AOR= 2.36; CI: 1.01, 5.55), premature rapture of membrane (AOR= 4.88; CI: 2.33, 10.21), pregnancy induced hypertension (AOR= 5.11; CI: 2.67, 9.79), and bishop score less than six (AOR= 1.95; CI: 1.15, 3.32) were significantly associated with failed induction of labour.Conclusion: The magnitude of failed induction of labour among mothers undergoing labor induction was relatively high in the study settings compared with previous studies in the country. Failed induction of labour was significantly associated with age of the mother (<30 years), rural residency, being primi-para, gestational age less than 37 or greater than 42 years, multiple ton of pregnancy, premature rapture of membrane, pregnancy induced hypertension, and bishop score less than six.

Risk of Cesarean Delivery for Women with Obesity Using a Standardized Labor Induction Protocol

Objective We aimed to determine the risk of cesarean among women with obesity undergoing labor induction within a prospective trial that utilized a standardized labor protocol. Study Design This was a secondary analysis of a randomized trial of induction methods. Term (≥37 weeks) women with intact membranes undergoing induction with an unfavorable cervix (Bishop's score ≤6 and dilation ≤2 cm) were included. The trial utilized a labor protocol that standardized induction and active labor management, with recommendations for interventions at particular time points. Only women with a recorded body mass index (BMI) at prenatal care start were included in this analysis. The primary outcome was cesarean delivery compared between obese (≥30 kg/m2) and nonobese (<30 kg/m2) women. Indication for cesarean was also evaluated. Results A total of 465 women were included: 207 (44.5%) obese and 258 (55.5%) nonobese. Women with obesity had a higher risk of cesarean compared with women without obesity (33.3 vs. 23.3%, p = 0.02), even when adjusting for parity, weight change over pregnancy, and indication for induction (adjusted relative risk [aRR] = 1.79, 95% confidence interval [CI]: [1.34–2.39]). Compared with women without obesity, women with obesity had a higher risk of failed induction (47.8 vs. 26.7%, p = 0.01) without a difference in arrest of active phase (p = 0.39), arrest of descent (p = 0.95) or fetal indication (p = 0.32), despite adherence to a standardized labor protocol. Conclusion Compared with women without obesity, women with obesity undergoing an induction are at increased risk of cesarean, in particular a failed induction, even within the context of standardized induction management. As standardized practices limit provider variation in labor management, this study may support physiologic differences in labor processes secondary to obesity. Key Points

Evaluation of Feto-maternal Outcome with Prelabour Rupture of Membranes in Term Pregnancy

Premature rupture of membrane (PROM) is defined as the disruption of fetal membranes before the beginning of labor, resulting in spontaneous leakage of amniotic fluid. The present study is undertaken to study the labor outcome, maternal morbidity and perinatal morbidity and mortality in term PROM. This is a Prospective Observational and Descriptive type Study conducted at Government Medical college, Kota for a period of eighteen month from January 2019 to June 2020. 200 cases of Spontaneous rupture of membrane with term gestation and confirmed by per speculum examination were selected. PROM was common in primigravida (62.50%), majority of belonged to age group of 20-29 years (89.0%). Need of induction required in 88% of cases, induction by cerviprime-gel done in 84.5% cases, Cesarean sections were more among primigravida. Failed induction was the common indication (44.11%). Maternal morbidity was significant (20.0%). Febrile morbidity was the major morbidity noticed with 14.50% followed by PPH 1.5%. No maternal mortality in the study. Perinatal morbidity was seen in 21% of cases. Birth asphyxia was the commonest cause for perinatal morbidity (14.0%). No Perinatal mortality was seen in this study. Escherichia coli (16.50%) was common organism found in culture of amniotic fluid. Majority of babies had APGAR score 6 &7 at 1 minute of birth and APGAR score 9 and 10 at 5 min. of birth. PROM is associated with many complications which can be reduced, by educating the women to have regular antenatal care, and early recognition of genital tract infection, and treat appropriately and to report at the earliest.

Predicting factors of failed induction of labor in three hospitals of Southwest Ethiopia: a cross-sectional study

Introduction Failed induction of labor affects maternal and neonatal outcomes as well as the cost of healthcare, especially in low-resource setting regions in which the prevalence of failed induction is higher despite the incidence of labor induction is low. This study aimed to assess the prevalence of failed induction of labor in southwest Ethiopia. Method A hospital-based cross-sectional study was conducted among 441 induced women from March 1 to August 30, 2018. A systematic random sampling technique was used to select study participants. Data were collected using a pretested and structured questionnaire. Bivariable and multivariable logistic regression models were done and fitted to identify predictors of failed induction. An adjusted odds ratio with 95% confidence interval (CI) was calculated to determine the level of significance. Result Premature rupture of membrane was the most common cause of labor induction and the commonly used method of labor induction were oxytocin infusion. Cesarean section was done for 28.1% of induced women. Failed induction of labor was found to be 21%. Primiparous [AOR = 2.35 (1.35–4.09)], analgesia/anesthesia [AOR = 4.37 (1.31–14.59)], poor Bishop Score [AOR = 2.37 (1.16–4.84)], Birth weight ≥ 4 k grams [AOR = 2.12 (1.05–4.28)] and body mass index [AOR = 5.71 (3.26–10.01)] were found to be significantly associated with failed induction of labor. Conclusion The prevalence of failed induction of labour was found to be high. Preparation of the cervix before induction in primi-parity women is suggested to improve the success of induction. To achieve the normal weight of women and newborns, proper nutritional interventions should be given for women of reproductive age. It is better to use analgesia/anesthesia for labor induction when it becomes mandatory and there are no other optional methods of no- pharmacologic pain management.

Delayed subaponeurotic fluid collection on an infant’s head: Underreported case and review of the literature

Background: Delayed subaponeurotic fluid collection (DSFC) is a relatively uncommon problem, probably under reported soft swelling in the scalp which usually develops in infancy that occurs weeks to months after birth. Although the exact etiology remains unclear, several theories have been postulated such as (i) cerebrospinal fluids (CSF) leak from microfractures of the skull and (ii) disrupted lymphatic drainage, gradually liquefying subaponeurotic bleeding. Here, we reported typical clinical findings of DSFC and analysis of the fluid aspirate from our patient. To the best of our knowledge, this is the first case reported from Asia, particularly from Indonesia. Case Description: A healthy 2-month-old girl infant presented with 2 weeks history of occipital painless fluctuant scalp mass with no swelling. She was born at term from a nulliparous mother; by emergency cesarean delivery following failed induction of labor. There was no history of scalp injury at birth nor recent head trauma; ultrasonography showed translucent fluid in subaponeurotic or subgaleal space. The fluid collection was noted to be fluctuant, free-flowing across suture lines, without discoloration or bruising; when placed supine, the fluid collected at her midocciput. A diagnostic tap confirmed the presence of serosanguinous CSF led to a diagnosis of DSFC. Conclusion: Herein, we reported the first DSFC case from Indonesia. With no previous experience of the condition, a definitive diagnosis was possible through a very carefully physical examination and history taking, along with a good communication among the neurosurgeon, pediatrician, and the clinical pathologist.

Enfermedad de Von Willebrand como factor de riesgo para hemorragia postparto. Reporte de caso

The Von Willebrand´s disease is the most common inherited bleeding disorder, with higher prevalence in women in fertile age. There are three principle types, that are caused by either a quantitative or qualitative defect in von Willebrand factor and in severe cases, the coagulation factor VIII is affected too. The incidence in pregnancy is relatively infrequent, however there are worldwide reports where it has been considered a risk factor for bleeding during the resolution of pregnancy. We present the case of a 20-year-old woman on her second pregnancy, with a previous abortion, who had a full-term pregnancy with a diagnosis of Von Willebrand disease since she was twelve years old, treated with nasal desmopression only in the presence of hemorrhagic events. Gestation was terminated via abdominal route due to failed induction, and in spite of preoperative hematologic and anesthetic prophylactic management, she presented postpartum hemorrhage, according to current definitions based on national and international guidelines, attributing the cause of the bleeding to the patient's coagulopathy. Keywords: Von Willebrand´s disease; pregnancy; postpartum hemorrhage.

Factors and outcomes associated with the induction of labor in referral hospitals of Amhara regional state, Ethiopia: a multicenter study

Background Induction of labor is an artificial initiation of uterine contractions after fetal viability with the aim of vaginal delivery prior to the onset of spontaneous labor. Prevalence of induction of labor is increasing worldwide with subsequent increase in failure rate. However, there is limited evidence on labor induction in Ethiopia. Therefore, this study was aimed at assessing the prevalence and associated factors of failed induction of labor among women undergoing induction of labor at referral hospitals of Amhara national regional state, Ethiopia, 2016. Method A multicenter cross-sectional study was conducted at referral hospitals found in Amhara national regional state from February 01 to September 30, 2016. Multistage sampling technique was employed to select a total of 484 women who underwent labor induction. Pre-tested structured questionnaires and checklists were used to collect the data. Data were entered into EPI info version 7 and analyzed using SPSS version 20 software. Stepwise Binary Logistic regression model was fitted to identify factors associated with failed induction of labor. The level of significance was determined based on the adjusted odds ratio with 95% confidence interval at the p-value of ≤0.05. Result The prevalence of failed induction of labor among women undergoing induction of labor was 31.4% (95% CI: 27.0, 36.0). Failed induction of labor was independently predicted by a Bishop score of ≤5 (AOR = 2.1; 95% CI: 1.3, 3.6), prolonged latent first stage of labor (AOR = 2.0; 95% CI: 1.2, 3.5), induction with oxytocin alone (AOR = 4.2; 95% CI: 2.2, 8.1), nulliparity (ARO = 1.9; 95% CI: 1.2, 2.9), post term pregnancy (AOR = 4.1; 95% CI: 1.8, 9.3) and hypertensive disorder of pregnancy (AOR = 2.4; 95% CI: 1.5, 5.1). Conclusion Failed induction of labor was high in the study area compared to the reports of previous studies done in Ethiopia. The majority of the determinants of failed induction of labor were connected with unjustifiable and inconsistent indication of induction of labor. Thus, preparing standardized practical guidelines and preventing unjustifiable case selection may help reduce the current high failure rates.
