Does the timing of postprandial glucose monitoring affect the obstetric and neonatal outcomes in patients with gestational diabetes? A prospective study comparing 1 and 2-h postprandial monitoring

OBJECTIVE

The aim of this study was to examine the obstetrical and neonatal outcomes in patients with gestational diabetes mellitus (GDM) who had postprandial glucose monitoring 1 vs. 2 h following meals.

STUDY DESIGN

In this prospective cohort study, we included patients with GDM who were referred to our medical center between July 2019 and June 2021. Patients chose the timing of postprandial glucose monitoring based on their own preferences. Obstetrical and neonatal outcomes, as well as patient satisfaction, were compared between patients who performed postprandial glucose monitoring 1 and 2 h after meals (PPG1 vs. PPG2). The primary outcome was birth weight. The study was powered to detect a 250 g increase in birth weight.

RESULTS

Overall, 99 patients were included: 50 in the PPG1 group and 49 in the PPG2 group. Baseline characteristics were comparable between the groups. Neonates in the PPG1 and PPG2 groups had similar birth weights (3319 ± 355 vs. 3319 ± 520 g, respectively, p = 0.99). Glycemic control, mode of delivery, gestational age at delivery, and satisfaction rates were also similar between the study groups.

CONCLUSION

In patients with GDM, performing1 vs. 2 h following meals resulted in similar obstetrical and neonatal outcomes and similar satisfaction rates. We therefore recommend counseling patients to choose either strategy based on their personal preference.

Association between mode of delivery and early neurodevelopment: A prospective birth cohort study

Previous research has assessed the effects of caesarean delivery (CD) on child neurodevelopment; however, whether the effects stem from the surgical procedure itself or its related medical conditions has not been conclusively determined. This study aimed to evaluate the associations among delivery mode, CD-related medical conditions and early childhood neurodevelopment. A total of 3829 maternal-infant pairs from a longitudinal birth cohort in Wuhan City, China, were included in the primary analysis. The neurodevelopment of the children was assessed by the Bayley Scales of Infant Development (BSID), the Conners Comprehensive Behaviour Rating Scale and the Chinese version of the Autism Behavior Checklist. Data on delivery mode and medical conditions were collected via medical records from the study hospital. Among the 3829 children for whom the BSID test was completed at two years of age, 50%, 27%, and 23% were delivered vaginally, by necessary CD, and by elective CD, respectively. Compared with vaginally delivered children, Necessary CD was associated with a 16.67% decrease in Mental Development Index (MDI) scores and a 13.37% decrease in Psychomotor Development Index (PDI) scores, while elective CD showed a 20.63% and 20.99% decrease after FDR correction, respectively. Similarly, among the 2448 children for whom the CBRS was completed, necessary CD was found to be associated with conduct disorders (adjusted β: 0.06; 95% CI: 0.02, 0.09), hyperactivity (adjusted β: 0.06; 95% CI: 0.02, 0.11), and hyperactivity index (adjusted β: 0.07; 95% CI: 0.03, 0.11), while elective CD was significantly associated with hyperactivity problem scores (adjusted β: 0.08, 95% CI: 0.03, 0.13). However, no significant association was found between CD and symptoms of autism in children, as assessed by the Autism Behavior Checklist (ABC).

CONCLUSION

This study suggested that the adverse impact of CD on child neurodevelopment stems from the procedure itself rather than CD-related medical conditions. It is important to minimize the use of CD when there is no medical necessity.

WHAT IS KNOWN

• Caesarean delivery (CD) may influence child neurodevelopment and other long-term outcomes. • In China, approximately one-quarter of CD are performed due to maternal request without medical indications.

WHAT IS NEW

• The negative impact of CD on the neurodevelopmental outcomes of children may be primarily attributed to the procedure itself, as opposed to related medical conditions. • In the absence of medical indications, unnecessary CD may have adverse impacts on children's neurodevelopment.

Establishing a risk score for prediction of intrapartum cesarean delivery among older women: A retrospective cohort study

OBJECTIVE

To determine risk factors and to develop a risk prediction score for intrapartum cesarean delivery (CD) in women over 40 years old.

STUDY DESIGN

A retrospective cohort study, in a single university-affiliated tertiary medical center. All women aged 40 years or more who planned a trial of labor between 2012 and 2022. Women who opted for an elective CD and those with non-viable fetuses were excluded. Maternal and neonatal characteristics of women who delivered vaginally were compared to those who underwent an intrapartum CD. Risk factors were examined using univariate and multivariate analysis. A score was developed to predict the need for intrapartum CD. We assessed a receiver operating characteristic curve to evaluate the performance of our model.

MAIN OUTCOME MEASURE

An unplanned intrapartum cesarean section.

RESULTS

During the study period, 122,583 women delivered at our center, of whom 6122 (4.9 %) aged 40 years or more attempted a trial of labor. Of them, 428 (7 %) underwent intrapartum CD. Several independent risk factors were identified, including nulliparity, regional anesthesia, induction of labor, use of antibiotics during labor, multiple gestation, previous cesarean delivery, and the presence of gestational diabetes or preeclampsia. A risk score model, employing a cut-off of 7, demonstrated successful prediction of intrapartum CD, with an area under the curve of 0.86.

CONCLUSION

The score model for intrapartum CD can be used by caregivers to offer a more informed consultation to women aged 40 years or more deciding on the mode of delivery.

Social disparities in delivery choice among patients with history of cesarean

OBJECTIVE

Given the call to reduce rates of non-medically indicated cesarean deliveries (CDs) by encouraging trials of labor after cesarean (TOLAC), this study looks at social characteristics of patients choosing a TOLAC versus a scheduled repeat cesarean delivery (SRCD) to determine disparities regarding delivery method choice.

METHODS

This was a retrospective cohort study of patients with a history of one CD between April 29, 2015-April 29, 2020. Patients were divided based on type of delivery chosen at admission. Chi-squared tests examined proportional differences between groups and logistic regression models examined odd ratios of choosing TOLAC versus SRCD according to socially dependent categories including race/ethnicity, health insurance, pre-pregnancy body mass index, and Social Vulnerability Index (SVI).

RESULTS

1,983 patients were included. Multivariable logistic regression models revealed that patients with a high SVI (reference: low/medium SVI) (AOR 2.0, CI: 1.5, 2.5), self-identified as Black/ African American (AOR: 2.4, CI: 1.6, 3.6) or Hispanic/Latina (AOR: 2.0, CI: 1.4, 2.8) (reference: White), had public insurance (reference: private insurance) (AOR: 3.7, CI: 2.8, 5.0), and who had an obese BMI (reference: non-obese BMI) were more likely to opt for a TOLAC rather than SRCD.

CONCLUSION

These findings demonstrate differences in delivery method preferences. Specifically, more disadvantaged patients are more likely to choose TOLAC, suggesting that social and economic factors may play a role in delivery preferences. These findings have implications for improving individualized counselling and engaging in shared decision-making around mode of delivery.

Obstetric outcomes of nulliparous women with pelvic pain undergoing fertility treatment

RESEARCH QUESTION

Is there any association between pelvic pain and primary caesarean delivery for patients undergoing assisted reproductive technology (ART) treatment?

DESIGN

Retrospective cohort study of nulliparous patients with singleton pregnancies who underwent ART treatment and achieved a live birth between 2012 and 2020. Cases included patients diagnosed with pelvic pain. A 3:1 ratio propensity-score-matched population of patients without a history of pelvic pain was included as the control group. Comparative statistics were performed using chi-squared test and Student's t-test. A multivariate regression analysis was conducted to evaluate the association between pelvic pain and mode of delivery.

RESULTS

One hundred and seventy-four patients with pelvic pain were compared with 575 controls. Patients with pelvic pain reported a significantly longer duration of infertility compared with controls (18.98 ± 20.2 months versus 14.06 ± 14.06 months; P = 0.003). Patients with pelvic pain had a significantly higher rate of anxiety disorders (115 ± 21.9 versus 55 ± 31.6; P = 0.009) and use of anxiolytics at embryo transfer (17 ± 3.2 versus 12 ± 6.9; P = 0.03) compared with controls. In addition, patients with pelvic pain had a higher rate of primary caesarean delivery compared with controls (59.8% versus 49.0%; P = 0.01). After adjusting for multiple variables, a significant association was found between pelvic pain and increased odds of primary caesarean delivery (adjusted OR 1.48, 95% CI 1.02-2.1).

CONCLUSION

Patients with pelvic pain have significantly higher odds of primary caesarean delivery compared with patients without a history of pelvic pain. The infertility outpatient setting may be uniquely positioned to identify patients at risk for undergoing primary caesarean delivery, and could facilitate earlier intervention for pelvic floor physical therapy during the preconception and antepartum periods.

The mode of delivery after operative fixation of pelvic ring fractures-a retrospective observational study

PURPOSE

The purpose of this study is to investigate whether retained hardware after surgical treatment for a pelvic fracture prior to pregnancy affects the choice of delivery method. The study aims to provide insights into the rates of vaginal delivery and caesarean sections, understanding whether the mode of delivery was influenced by patient preference or the recommendations of obstetricians or surgeons, and examining the rate of complications during delivery and postpartum.

METHODS

All women of childbearing age who underwent surgical fixation for a pelvic ring fracture between 1994 and 2021 were identified. A questionnaire was sent about their possible pregnancies and deliveries. Of the included patients, surgical data were collected and the fracture patterns were retrospectively classified. Follow-up was a minimum of 36 months.

RESULTS

A total of 168 women with a pelvic fracture were identified, of whom 13 had a pregnancy after surgical stabilization. Eleven women had combined anterior and posterior fracture patterns and two had isolated sacral fractures. Four women underwent combined anterior and posterior fixation, the others either anterior or posterior fixation. Seven women had a total of 11 vaginal deliveries, and 6 women had 6 caesarean sections. The decision for vaginal delivery was often the wish of the mother (n = 4, 57%) while the decision to opt for caesarean section was made by the surgeon or obstetrician (n = 5, 83%). One woman in the vaginal delivery group suffered a postpartum complication possibly related to her retained pelvic hardware.

CONCLUSION

Women with retained hardware after pelvic ring fixation can have successful vaginal deliveries. Complications during labor or postpartum are rare. The rate of primary caesarean sections is high (46%) and is probably influenced by physician bias. Future research should focus on tools that can predict labor outcomes in this specific population, and larger multicenter studies are needed.

Prevalence of delivery mode in an Italian nationwide cohort with celiac disease: a SIGENP multicenter retrospective study (the CD-deliver-IT)

BACKGROUND

Studies have indicated an association between cesarean section (CS), especially elective CS, and an increased risk of celiac disease (CD), but the conclusions of other studies are contradictory. The primary aim of this study (CD-deliver-IT) was to evaluate the rate of CS in a large population of CD patients throughout Italy.  METHODS: This national multicenter retrospective study was conducted between December 2020 and November 2021. The coordinating center was the Pediatric Gastroenterology and Liver Unit of Policlinico Umberto I, Sapienza, University of Rome, Lazio, Italy. Eleven other referral centers for CD have participated to the study. Each center has collected data on mode of delivery and perinatal period of all CD patients referring to the center in the last 40 years.

RESULTS

Out of 3,259 CD patients recruited in different Italian regions, data on the mode of delivery were obtained from 3,234. One thousand nine hundred forty-one (1,941) patients (60%) were born vaginally and 1,293 (40%) by CS (8.3% emergency CS, 30.1% planned CS, 1.5% undefined CS). A statistically significant difference was found comparing median age at time of CD diagnosis of patients who were born by emergency CS (4 years, CI 95% 3.40-4.59), planned CS (7 years, CI 95% 6.02-7.97) and vaginal delivery (6 years, CI 95% 5.62-6.37) (log rank p < 0.0001).

CONCLUSIONS

This is the first Italian multicenter study aiming at evaluating the rate of CS in a large population of CD patients through Italy. The CS rate found in our CD patients is higher than rates reported in the general population over the last 40 years and emergency CS seems to be associated with an earlier onset of CD compared to vaginal delivery or elective CS in our large nationwide retrospective cohort. This suggests a potential role of the mode of delivery on the risk of developing CD and on its age of onset, but it is more likely that it works in concert with other perinatal factors. Further prospective studies on other perinatal factors potentially influencing gut microbiota are awaited in order to address heavy conflicting evidence reaming in this research field.

Effect of mode of delivery on postpartum weight retention: A systematic review and meta-analysis

OBJECTIVE

Retention of weight gained over pregnancy increases the risk of long-term obesity and related health concerns. While many risk factors for this postpartum weight retention have been examined, the role of mode of delivery in this relationship remains controversial. We carried out a systematic review and meta-analysis to determine the effect of mode of delivery on postpartum weight retention.

METHODS

Ten electronic databases including PubMed, Cochrane Library, EMBASE, Web of Science, MEDLINE, CINAHL, China National Knowledge Infrastructure (CNKI), Wan-Fang database, the VIP database and China Biology Medicine Database (CBM) were searched from inception through November 2022. Review Manager 5.4 was used to pool the study data and calculate effect sizes. For dichotomous data, the odds ratio and 95 % confidence interval were used to report the results. For continuous data, the mean difference (MD) and 95 % confidence interval were used to report the results. The outcomes were the amount of postpartum weight retention and the number or proportion of women who experienced postpartum weight retention. The Newcastle- Ottawa Scale (NOS) and GRADE Guidelines were used to assess the methodological quality of the included studies.

FINDINGS

A total of 16 articles were included in the systematic review and 13 articles were included in the meta-analysis. The results showed that the mode of delivery had a significant effect on postpartum weight retention, women who delivered by caesarean section were more likely to experience postpartum weight retention compared to those who delivered vaginally. Sensitivity analysis showed that the results were stable and credible.

CONCLUSION

Due to the limitations of this study, the findings need to be treated with caution. And, to better prevent the postpartum weight retention, future practice and research need to further focus on upstream modifiable factors.

Continued versus discontinued oxytocin stimulation in the active phase of labour (CONDISOX): individual management based on artificial intelligence - a secondary analysis

BACKGROUND

Current guidelines regarding oxytocin stimulation are not tailored to individuals as they are based on randomised controlled trials. The objective of the study was to develop an artificial intelligence (AI) model for individual prediction of the risk of caesarean delivery (CD) in women with a cervical dilatation of 6 cm after oxytocin stimulation for induced labour. The model included not only variables known when labour induction was initiated but also variables describing the course of the labour induction.

METHODS

Secondary analysis of data from the CONDISOX randomised controlled trial of discontinued vs. continued oxytocin infusion in the active phase of induced labour. Extreme gradient boosting (XGBoost) software was used to build the prediction model. To explain the impact of the predictors, we calculated Shapley additive explanation (SHAP) values and present a summary SHAP plot. A force plot was used to explain specifics about an individual's predictors that result in a change of the individual's risk output value from the population-based risk.

RESULTS

Among 1060 included women, 160 (15.1%) were delivered by CD. The XGBoost model found women who delivered vaginally were more likely to be parous, taller, to have a lower estimated birth weight, and to be stimulated with a lower amount of oxytocin. In 108 women (10% of 1060) the model favoured either continuation or discontinuation of oxytocin. For the remaining 90% of the women, the model found that continuation or discontinuation of oxytocin stimulation affected the risk difference of CD by less than 5% points.

CONCLUSION

In women undergoing labour induction, this AI model based on a secondary analysis of data from the CONDISOX trial may help predict the risk of CD and assist the mother and clinician in individual tailored management of oxytocin stimulation after reaching 6 cm of cervical dilation.

Anesthetic management in pregnant women with Fontan circulation: a case series

BACKGROUND

Given the advances in medicine, women with Fontan circulation are now reaching childbearing age. However, data on the mode of delivery and anesthetic management of these patients are limited. We report the cases of five pregnant women with Fontan circulation.

CASE PRESENTATION

The mean age at delivery was 28 ± 3 years, and the mean gestational period was 34 weeks and 3 days. Anticoagulation therapy was switched from warfarin and aspirin to continuous intravenous heparin. The modes of delivery were scheduled cesarean section (C/S) in one, emergency C/S in three, and vaginal delivery with epidural labor analgesia in one patient. Three patients underwent C/S under regional anesthesia; one received general anesthesia. The perinatal complications were heart failure, worsening valve regurgitation, and postoperative hematoma in three, four, and two patients, respectively.

CONCLUSIONS

For C/S in women with Fontan circulation, regional anesthesia should be considered. Epidural labor analgesia can help prevent the decrease in pulmonary blood flow due to straining. We initiated labor analgesia or C/S with regional anesthesia at the appropriate time in four patients.

Mode of delivery and neonatal outcomes in preterm twins less than 32 weeks of gestation or birthweight under 1500 g: a systematic review and meta-analyses

BACKGROUND

The mode of delivery for twins born before 32 weeks of gestation remains controversial. Our purpose is to conduct a meta-analysis of twin pregnancies less than 32 weeks or twin weight less than 1500 g, so as to find a suitable delivery mode.

METHODS

We searched PubMed database, Cochrane Library database, and EMBASE database through December 2022. This protocol was registered with PROSPERO (CRD42023386946) prior to initiation. Studies that compared vaginal delivery to cesarean section for newborns less than 32 weeks of gestation or birthweight under 1500 g were included. The primary result was neonatal mortality rate. Secondary result was neonatal morbidity. The quality of literatures included in the research was evaluated in accordance with Newcastle-Ottawa Scale (NOS) literature quality evaluation scale. We use odds ratio (OR) as the effect index for binary variables. Point estimates and 95% confidence intervals (95% CI) were calculated. P < 0. 05 indicated statistically significant difference.

RESULTS

Our search generated 5310 articles, and a total of 8 articles comprising a total of 14,703 newborns were included in the analysis. The odds ratios of neonatal mortality rate were for twins delivered by vaginal delivery compared to cesarean section were 0.84 (95% CI 0.57-1.24, P = 0.38). The 5-min Apgar score < 7 (95% CI 0.44-1.75, P = 0.72), necrotizing enterocolitis (95% CI 0.81-1.19, P = 0.82), intraventricular hemorrhage (95% CI 0.41-1.86, P = 0.71), periventricular leukomalacia (95% CI 0.16-4.52, P = 0.84), bronchopulmonary dysplasia (95% CI 0.88-1.36, P = 0.42), and respiratory distress syndrome (95% CI 0.23-2.01, P = 0.48) were not statistically significant between the two groups.

CONCLUSION

We have observed that vaginal delivery does not confer an increased risk of neonatal morbidity and mortality in twins born before 32 weeks of gestation. However, the current results are affected by substantial heterogeneity and confounding factors. We still need high-quality randomized-controlled studies require to address this important question.

The impact of fear of childbirth on mode of delivery, postpartum mental health and breastfeeding: A prospective cohort study in Shanghai, China

BACKGROUND

The prevalence and impact of fear of childbirth (FOC) has not been sufficiently understood. We aimed to investigate the prevalence of FOC among Chinese population and its impact on mode of delivery, postpartum mental health and breastfeeding.

METHODS

We conducted a prospective cohort study, wherein pregnant women in their third trimester who underwent antenatal assessments at Shanghai Changning Maternity and Infant Health Hospital between September 2020 and March 2021 were recruited. Sociodemographic data of the participants were gathered by self-administered questionnaire, and their FOC was assessed using the Wijma Delivery Expectancy Questionnaire. Participants were followed up to 42 days postpartum. Information regarding their modes of delivery was retrieved from medical records, and data regarding postpartum mental health symptoms and one-month postpartum breastfeeding were obtained through self-administered questionnaires.

RESULTS

Among 1287 participants, 461 (35.8 %) had high-level FOC (W-DEQ ≥ 66). Logistic regressions showed that women with high-level of FOC had higher rates of caesarean delivery on maternal request (CDMR) (aOR = 1.55, 95 % CI: 1.00-2.41, p = 0.049), a higher incidence of postpartum mental health symptoms (aOR = 1.68, 95 % CI: 1.09-2.59, p = 0.018), lower rates of one-month postpartum exclusive breastfeeding (aOR = 0.33, 95 % CI: 0.16-0.69, p = 0.003) and mixed feeding (aOR = 0.44, 95 % CI: 0.21-0.91, p = 0.028).

LIMITATIONS

The long-term implications of FOC beyond the immediate postpartum period were not explored in the study.

CONCLUSIONS

High-level FOC during the third trimester was associated with increased CDMR and postpartum mental health symptoms and reduced breastfeeding establishment. These results underscore the significance of FOC screening and tailored interventions for affected women.

Impact of childbirth on pelvic floor dysfunction in women who have undergone previous pelvic floor reconstructive surgery: systematic review and meta-analysis

INTRODUCTION AND HYPOTHESIS

The aim of the study was to perform a systematic review and meta-analysis of the impact of pregnancy and childbirth (vaginal delivery [VD]) or cesarean section (CS) on the recurrence of pelvic floor disorders in women who had previously undergone pelvic floor reconstructive surgery for pelvic organ prolapse (POP) or stress urinary incontinence (SUI), to facilitate future evidence-based counseling.

METHODS

PubMed, Cochrane, Embase, BJOG, Scopus, etc. were screened, from 1990 to date. Inclusion criteria included cohort studies, case-control studies, case series, and case reports that reported on the primary outcome measure of the review. Exclusion criteria included studies on surgical procedures whose outcomes are unlikely to be impacted by pregnancy and childbirth or are obsolete. Meta-analysis was performed using Review Manager 5.3.

RESULTS

Seven papers on midurethral slings (MUS; 181 women in both VD and CS groups respectively) and three papers on different hysteropexy techniques (47 and 29 women in the VD and CS groups respectively), were included in the meta-analysis. No difference was seen between the two groups regarding the recurrence of SUI in women who had previously undergone MUS surgery (OR: 1.18 [0.66, 2.09]; Z = 0.56; p = 0.58) or the recurrence of POP following hysteropexy using various apical suspension procedures (OR: 1.81 [0.04, 80.65]; Z = 0.31; p = 0.76). There are insufficient data to support meta-analyses for individual MUS sub-types or hysteropexy procedures.

CONCLUSION

Current literature does not demonstrate a protective effect of CS in preventing recurrent SUI in women who had undergone MUS surgery for SUI. When hysteropexy is considered irrespective of the apical suspension procedure employed, the incidence of recurrent POP appears similar after CS and VD.

The Bern Birth Cohort (BeBiCo) to study the development of the infant intestinal microbiota in a high-resource setting in Switzerland: rationale, design, and methods

BACKGROUND

Microbiota composition is fundamental to human health with the intestinal microbiota undergoing critical changes within the first two years of life. The developing intestinal microbiota is shaped by maternal seeding, breast milk and its complex constituents, other nutrients, and the environment. Understanding microbiota-dependent pathologies requires a profound understanding of the early development of the healthy infant microbiota.

METHODS

Two hundred and fifty healthy pregnant women (≥20 weeks of gestation) from the greater Bern area will be enrolled at Bern University hospital's maternity department. Participants will be followed as mother-baby pairs at delivery, week(s) 1, 2, 6, 10, 14, 24, 36, 48, 96, and at years 5 and 10 after birth. Clinical parameters describing infant growth and development, morbidity, and allergic conditions as well as socio-economic, nutritional, and epidemiological data will be documented. Neuro-developmental outcomes and behavior will be assessed by child behavior checklists at and beyond 2 years of age. Maternal stool, milk, skin and vaginal swabs, infant stool, and skin swabs will be collected at enrolment and at follow-up visits. For the primary outcome, the trajectory of the infant intestinal microbiota will be characterized by 16S and metagenomic sequencing regarding composition, metabolic potential, and stability during the first 2 years of life. Secondary outcomes will assess the cellular and chemical composition of maternal milk, the impact of nutrition and environment on microbiota development, the maternal microbiome transfer at vaginal or caesarean birth and thereafter on the infant, and correlate parameters of microbiota and maternal milk on infant growth, development, health, and mental well-being.

DISCUSSION

The Bern birth cohort study will provide a detailed description and normal ranges of the trajectory of microbiota maturation in a high-resource setting. These data will be compared to data from low-resource settings such as from the Zimbabwe-College of Health-Sciences-Birth-Cohort study. Prospective bio-sampling and data collection will allow studying the association of the microbiota with common childhood conditions concerning allergies, obesity, neuro-developmental outcomes , and behaviour.

Association of maternal, fetal and labor variables with a low Apgar score in the fifth minute in term pregnancy: a case-control study

PURPOSE

To search for maternal, labor-related and fetal variables associated with low Apgar in the fifth minute in term pregnancy.

METHODS

A retrospective case-control study with term births was conducted in a public teaching hospital from 2013 to 2020. Cases were term births with Apgar score less than 7 in the fifth minute, and controls, the next one or two births following a case, with Apgar of 7 or more. Non-cephalic presentations, multiples and malformations were excluded. We accessed 100 cases and 190 controls. We considered significant values of p < 0.05.

RESULTS

Were accessed 27 variables which could be risk factors, from which 12 were associated with the outcome. We found a protective effect of prelabor cesarean for the outcome, odds ratio (OR) 0.38, p = 0.013. Consequently, we conducted two sets of analyses: in the whole group and in the group of laboring women. The values of OR were in general greater in the group of laboring women, compared with the whole group. We conducted multivariate analysis within the group of women in labor. The variables which fitted best in the model were nulliparity, male sex of the fetus, less than six prenatal visits and abnormal cardiotocography; all remained significant. An association of rupture of membranes more than 360 min with the outcome, even after controlling fpr duration of labor, was found; adjusted OR 2.45, p = 0.023.

CONCLUSION

Twelve variables were associated with the outcome. Prelabor cesarean had a protective effect. The time of ruptured membranes was associated with low Apgar.

Factors affecting the need for silicon tube implantation in cases of congenital dacriostenosis: time of delivery, type of delivery and age of operation

PURPOSE

To evaluate the delivery time, type of delivery, age at the time of operation, and surgical methods applied in cases of congenital nasolacrimal duct obstruction (CNLDO).

METHODS

This study retrospectively included a total of 207 eyes of 160 cases who underwent surgery for CNLDO between February 2012 and April 2021. According to their age at the time of operation, the cases were divided into 0-12, 12-24, 24-36, 36-48 and > 48 months groups. The cases were evaluated as term/preterm according to the delivery time and cesarean section/vaginal delivery according to the type of delivery. The surgical methods applied were examined as probing alone and probing plus silicone tube implantation.

RESULTS

Of the cases, 146 (91.2%) were born at term and 14 (8.7%) were born preterm, and there was no statistically significant difference in the silicone tube implantation rates according to the time of delivery. The rate of silicone tube implantation was statistically significantly higher in the vaginal delivery group than in the cesarean section group (p = 0.001; p < 0.01). The rate of silicone tube implantation was higher in those who were older than the age of the operation.

CONCLUSIONS

Although the rate of those who were born by cesarean section was higher in probing cases, those who required silicone intubation were more common in those who were born vaginally. This suggests that dacryostenosis in the vaginally born cases resulted from a persistent structural and anatomical obstruction despite the presence of a high intrauterine pressure increase and enzymatic lysis.

Preferred mode of delivery and its associated factors in pregnant women with a previous cesarean scar at a tertiary care hospital in Ethiopia: institutional-based cross-sectional study

BACKGROUND

Vaginal births after cesarean or elective repeat cesarean sections (CS) are the options for delivery after one cesarean scar. However, there is a lack of data regarding the preferred next mode of delivery in Ethiopia after a previous cesarean section. Thus, this study assessed the preferred mode of delivery and determinants after one previous CS in the antenatal clinic at the University of Gondar Comprehensive Specialized Hospital (UoGCSH).

METHODS

An institutional-based cross-sectional study was conducted among pregnant mothers with one previous CS at UoGCSH from March to August 2022. Structured questionnaires were used to collect the data. The collected data were entered, cleaned, and edited using Epi-data 4.6 and exported to SPSS version 26 for analysis. A binary logistic regression was performed to assess the determinants of the preferred mode of delivery. A p-value of < 0.05 at the 95% confidence level (CI) was considered statistically significant.

RESULTS

The majority, 71.5% (95% CI: 64.7, 77.1), of participants preferred the trial of labor after cesarean (TOLAC) as their mode of delivery. Mothers who were married (AOR = 4.47, 95% CI: 1.19-16.85), had a diploma educational level (AOR = 3.77, 95% CI: 1.84-12.36), had previous post-cesarean complications (AOR = 3.25, 95% CI: 1.08-9.74), and knew about the success of the trial of labor after cesarean (AOR = 13.56, 95% CI: 4.52-37.19) were found to prefer the trial of labor compared with their counterparts.

CONCLUSION

This study concluded that most pregnant mothers preferred labor trials after one CS, which is a bit lower but comparable with recommended practice guidelines. Providing adequate information and counseling mothers to make informed decisions about their preferred mode of delivery could be substantial.

A history of cesarean section and future maternal long-term risk for neoplasms: a population-based cohort study

OBJECTIVE

Mode of delivery has long-term implications on the mother, including recent data regarding the level of transmission of fetal microchimeric cells (FMc) and their possible effect on cancer development. We aimed to evaluate the association between cesarean section (CS) and future risk for neoplasms.

STUDY DESIGN

A population-based cohort analysis comparing the long-term risk for neoplasms between patients that delivered only by CS to those that delivered only vaginally (VD). Neoplasms were pre-defined based on ICD-9 codes. Deliveries occurred between the years 1991-2017 in a tertiary medical center. Kaplan-Meier survival curves were used to compare the cumulative incidence of neoplasms and Cox proportional hazards models were constructed to control for confounders.

RESULTS

During the study period 105,992 patients met the inclusion criteria; 14150 (13.4%) of patients had only CS and 91842 (86.6%) had VD (comparison group). The CS group had significantly higher incidence of benign and malignant neoplasms (4.73 per 1000 patient-years versus 3.88 per 1000 patient-years, OR = 1.26, 95% CI 1.16-1.37; p = 0.001; 2.19 per 1000 patient-years of follow up versus 1.93 per 1000 patient-years, OR = 1.16, 95% CI 1.03-1.31; p = 0.013). Specifically, the CS group had higher incidence of uterine cancer (1.2 versus 0.06 per 1000 patient-years, OR = 1.97, 95% CI 1.14-3.39; p = 0.013). The cumulative incidence of benign, malignant and uterine neoplasms was significantly higher in the CS group (Log rank test p = 0.001; 0.036 and 0.014; respectively). Importantly, no significant association was found with breast and ovarian malignancies." When performing a Cox regression model controlling for confounders, the risk for malignancy-related hospitalizations remained significant (adjusted HR = 1.22, 95% CI 1.01-1.48; p = 0.031) but not for uterine cancer (adjusted HR = 1.6, 95% CI 0.9-2.8; p = 0.103).

CONCLUSION

Our findings provide support to linkage between delivery by cesarean section and future maternal malignancy.

Uncharted territory: a narrative review of parental involvement in decision-making about late preterm and early term delivery

Almost 30% of live births in England and Wales occur late preterm or early term (LPET) and are associated with increased risks of adverse health outcomes throughout the lifespan. However, very little is known about the decision-making processes concerning planned LPET births or the involvement of parents in these. This aim of this paper is to review the evidence on parental involvement in obstetric decision-making in general, to consider what can be extrapolated to decisions about LPET delivery, and to suggest directions for further research.A comprehensive, narrative review of relevant literature was conducted using Medline, MIDIRS, PsycInfo and CINAHL databases. Appropriate search terms were combined with Boolean operators to ensure the following broad areas were included: obstetric decision-making, parental involvement, late preterm and early term birth, and mode of delivery.This review suggests that parents' preferences with respect to their inclusion in decision-making vary. Most mothers prefer sharing decision-making with their clinicians and up to half are dissatisfied with the extent of their involvement. Clinicians' opinions on the limits of parental involvement, especially where the safety of mother or baby is potentially compromised, are highly influential in the obstetric decision-making process. Other important factors include contextual factors (such as the nature of the issue under discussion and the presence or absence of relevant medical indications for a requested intervention), demographic and other individual characteristics (such as ethnicity and parity), the quality of communication; and the information provided to parents.This review highlights the overarching need to explore how decisions about potential LPET delivery may be reached in order to maximise the satisfaction of mothers and fathers with their involvement in the decision-making process whilst simultaneously enabling clinicians both to minimise the number of LPET births and to optimise the wellbeing of women and babies.

Cesarean section rates according to the Robson Classification and its association with adequacy levels of prenatal care: a cross-sectional hospital-based study in Brazil

BACKGROUND

The rate of Cesarean section (CS) deliveries has been increasing worldwide for decades. Brazil exhibits high rates of patient-requested CS deliveries. Prenatal care is essential for reducing and preventing maternal and child morbidity and mortality, ensuring women's health and well-being. The aim of this study was to verify the association between the level of prenatal care, as measured by the Kotelchuck (APNCU - Adequacy of the prenatal care utilization) index and CS rates.

METHODS

We conducted a cross-sectional study based on data from routine hospital digital records and federal public health system databases (2014-2017). We performed descriptive analyses, prepared Robson Classification Report tables, and estimated the CS rate for the relevant Robson groups across distinct levels of prenatal care. Our analysis also considered the payment source for each childbirth - either public healthcare or private health insurers - and maternal sociodemographic data.

RESULTS

CS rate by level of access to prenatal care was 80.0% for no care, 45.2% for inadequate, 44.2% for intermediate, 43.0% for adequate, and 50.5% for the adequate plus category. No statistically significant associations were found between the adequacy of prenatal care and the rate of cesarean sections in any of the most relevant Robson groups, across both public (n = 7,359) and private healthcare (n = 1,551) deliveries.

CONCLUSION

Access to prenatal care, according to the trimester in which prenatal care was initiated and the number of prenatal visits, was not associated with the cesarean section rate, suggesting that factors that assess the quality of prenatal care, not simply adequacy of access, should be investigated.

Association between Cesarean section and neurodevelopmental disorders in a Japanese birth cohort: the Japan Environment and Children's Study

BACKGROUND

The long-term effects of a Cesarean section (CS) birth on child neurodevelopment are of increasing interest. In this study, we examined the associations between mode of delivery and presence of neurodevelopmental disorders in toddlers. Moreover, given that the prevalence of several neurodevelopmental disorders such as autism spectrum disorder (ASD) is known to differ by sex, we also investigated these associations separately in male and female toddlers.

METHODS

We investigated 65,701 mother-toddler pairs from the Japan Environment and Children's Study, a nationally representative children's cohort study. To investigate the associations between mode of delivery (CS or vaginal delivery) and neurodevelopmental disorders (motor delay, intellectual disability, and ASD) in 3-year-old toddlers as a whole and stratified by sex, we used logistic regression models to calculate adjusted odds ratios (aORs) with 95% confidence intervals (CIs).

RESULTS

The morbidity of ASD at age 3 years was higher for children delivered by CS than those delivered vaginally (aOR 1.38, 95% CI 1.04-1.83). However, no such difference was evident in the case of motor delay or intellectual disability (aOR 1.33, 95% CI 0.94-1.89; aOR 1.18, 95% CI 0.94-1.49, respectively). In the analysis by sex, CS was not associated with increased risk of any of the neurodevelopmental disorders in males, but it was associated with increased risks of motor delay (aOR 1.88, 95% CI 1.02-3.47) and ASD (aOR 1.82, 95% CI 1.04-3.16) in females.

CONCLUSIONS

This study provides evidence of significant associations between mode of delivery and neurodevelopmental disorders in early childhood. Females may be more sensitive to the effects of CS than males.

Trial of labor versus elective cesarean delivery for patients with two prior cesarean-sections: A retrospective propensity score analysis

INTRODUCTION

Despite awareness of obstetricians to the constant increase in the number of cesarean sections in recent years, the fear of a uterine scar rupture is still present and influences the choice of the mode of delivery in patients with two previous cesarean sections. However, several clinical studies have suggested that, under certain conditions, vaginal birth after two cesarean sections is usually successful and safe.

OBJECTIVE

The objective of this study was to compare maternal and neonatal issues according to the planned mode of delivery in patients with two previous cesarean sections.

METHODS

It was a retrospective observational comparative study at Rennes University Hospital between January 1, 2013, and December 31, 2020. We performed a propensity score for the comparison of neonatal outcomes: cord pH, cord lactates, Apgar scores, transfer to neonatal unit and deaths, according to the planned delivery mode. Secondary outcomes were maternal issues: uterine rupture, post-partum hemorrhage, deaths.

RESULTS

A total of 410 patients with two previous cesarean section were eligible for our study. Prophylactic cesarean was performed in 358 cases (87.3%). Trial of labor was attempted in the 52 remaining patients (12.7%), 67.3 % of whom were successful. Neonatal weight, APGAR score at 1-5-10 min, and pH on cord blood were comparable in both groups. One case of uterine rupture occurred in the trial of labor group.

CONCLUSION

Trial of labor seems to be a reasonable option for women with two previous cesarean sections in a selected population.

Exploring trends of severe postpartum haemorrhage: a hospital-based study

BACKGROUND

Over the past two decades several high-income countries have reported increased rates of postpartum haemorrhage (PPH). Many of the studies are registry studies with limited access to detailed information. We aimed to explore trends of severe PPH in the largest labour ward in Norway during a 10-year period with a hospital based study. Our population constituted all women who gave birth after week 22 at Oslo University Hospital between 2008 and 2017. The main outcome measure was severe PPH, defined as registered blood loss greater than 1500 ml, or transfusion of blood products due to PPH.

METHODS

We estimated the incidence of severe PPH and blood transfusions, and performed temporal trend analysis. We performed Poisson regression analysis to investigate associations between pregnancy characteristics and severe PPH, presented using crude incidence rate ratios (IRR) with 95% confidence intervals (CI)s. We also estimated annual percentage change of the linear trends.

RESULTS

Among 96 313 deliveries during the 10-year study period, 2621 (2.7%) were diagnosed with severe PPH. The incidence rate doubled from 17.1/1000 to 2008 to 34.2/1000 in 2017. We also observed an increased rate of women receiving blood transfusion due to PPH, from 12.2/1000 to 2008 to 27.5/1000 in 2017. The rates of invasive procedures to manage severe PPH did not increase, and we did not observe a significant increase in the number of women defined with maternal near miss or massive transfusions. No women died due to PPH during the study period.

CONCLUSION

We found a significant increasing trend of severe PPH and related blood transfusions during the 10-year study period. We did not find an increase in massive PPH, or in invasive management, and we suspect that the rise can be at least partly explained by increased awareness and early intervention contributing to improved registration of severe PPH.

Role of mode of induction and delivery and women's satisfaction after induction of labour at term: An observational study

This cross-sectional study aimed at evaluating the impact of different modalities of induction of labour (IOL) and delivery on levels of woman' satisfaction. All women aged 18 years or older, who underwent IOL for at-term pregnancy (≥41 weeks of gestation) in randomly selected days during the study period in 6 participating centres were eligible for the study. The questionnaire investigated women's opinion regarding information about induction, pain control, length of induction, their experience about induction, labour and delivery and their attitude towards induction in a subsequent pregnancy. Women were also asked to fill in the Italian version of the Birth Satisfaction Scale-Revised (BSS-R). A total of 300 women entered the study. The answer to the question about a "positive attitude towards induction in a subsequent pregnancy was "absolutely yes" or "yes" respectively in the 77.8%, 52.8% and 48.6% of women who were induced with oral drugs, vaginal drugs and Cook balloon (heterogeneity chi-square p = 0.05). The corresponding values for women who delivered vaginally or by caesarean section (CS) were 63.3% and 36.4% (chi-square p = 0.0009). The mean BSS-R total score was higher among women who underwent IOL with oral drugs than with vaginal drugs (p < 0.0001) or Cook Balloon (p < 0.0001), and among women who delivered vaginally than in those who delivered by CS (p < 0.0001). Women were asked "What do you think is important for a method of induction?": 47.3% (95% CI 41.7%-53.0%) of women answered that "should make the induction as painless as possible", 47.0% (95% CI 41.4%-52.7%) "should induce labour quickly", 44.3% (95% CI 38.8%-50.0%) "should be safe for baby". This study showed that vaginal delivery was associated with a higher rate of satisfaction among induced women. Considering mode of induction, oral drugs were associated with a higher level of satisfaction. Control of pain and quick induction were the most appreciated characteristics.

The impact of mode of delivery on parent-infant-bonding and the mediating role of birth experience: a comparison of mothers and fathers within the longitudinal cohort study DREAM

BACKGROUND

The association between mode of delivery (MOD) and parent-infant-bonding has only been studied in mothers and findings have been inconclusive. The aim of this study was to prospectively investigate how MOD relates to postpartum parent-infant-bonding in both mothers and fathers and whether these associations are mediated by birth experience.

METHODS

This study is part of the prospective cohort study "Dresden Study on Parenting, Work, and Mental Health" (DREAM). Our sample comprised N = 1,780 participants who completed quantitative questionnaires during pregnancy as well as 8 weeks and 14 months postpartum. MOD was dummy coded, contrasting spontaneous vaginal delivery against vaginal delivery induced by drugs, operative vaginal delivery, planned, and unplanned cesarean section. Parent-infant bonding and birth experience were assessed using validated scales. A moderated mediation analysis based on ordinary least square (OLS) regression and bootstrapped estimates was conducted, considering relevant confounding variables.

RESULTS

Compared to spontaneous vaginal delivery, all categories of MOD predicted more negative birth experiences in both parents. A more positive birth experience predicted stronger parent-infant-bonding at 8 weeks, but not at 14 months postpartum. Mothers who delivered via cesarean section (planned or unplanned) reported stronger parent-infant-bonding at 8 weeks and 14 months postpartum. In fathers, only unplanned cesarean section was associated with stronger parent-infant-bonding at 8 weeks postpartum. At 8 weeks postpartum, birth experience mediated the association between a vaginal delivery induced by drugs and a planned cesarean section and mother-infant-bonding and between a vaginal delivery induced by drugs, an operative vaginal delivery, and planned cesarean section and father-infant-bonding. At 14 months postpartum, birth experience mediated the association between a vaginal delivery induced by drugs, operative vaginal delivery, and planned cesarean section and parent-infant-bonding in both parents.

CONCLUSIONS

The results emphasize the importance of the birth experience for parent-infant-bonding in both mothers and fathers. Further research should address the mechanisms by which parents with an unplanned cesarean section establish stronger parent-infant-bonding compared to parents whose baby was delivered via spontaneous vaginal delivery, despite their overall more negative birth experiences.
