A term large-for-gestational-age neonate was born via an uncomplicated normal vaginal delivery at a peripheral hospital. The neonate was referred to our tertiary centre due to concerns regarding the appearance of the right hand. On examination at 6 hours of life there was cyanotic discolouration

A girl born by normal vaginal delivery at 34 weeks’ gestation was noted to have a discrete midline scalp swelling from birth. This parieto-occipital lesion was non-tender, non-pulsatile and measured 10 mm in diameter. At 4 weeks of age, the lesion remained similar in size and had developed a

Uterus didelphus is a congenital abnormality arising from failure of fusion of Mullerian ducts, creating two separate uterine horns, two cervices and, in some cases, a vagina divided by a longitudinal septum. In this case, a 26-year-old woman with previously undiagnosed uterus didelphus spontaneously conceived dicavitary twins. Although initially wanting a vaginal birth, when both twins were in a breech presentation, a caesarean section was performed at 36 weeks, delivering two healthy babies. We will discuss the risk of obstetric complications in uterus didelphus and the challenges surrounding a vaginal delivery.

Glycogen storage disease type 1a (GSD 1a) is a metabolic disorder caused by deficiency of an enzyme required for glycogen breakdown, causing hypoglycaemia and lactic acidosis. Metabolic derangements cause disease manifestations affecting the kidneys, liver and platelet function. Physiological changes in pregnancy worsen fasting intolerance and increase reliance on exogenous glucose to avoid lactic acidosis. Fetal macrosomia and declining respiratory function result in high rates of caesarean sections. We report the multidisciplinary team (MDT) management of a 25-year-old woman with GSD 1a in an unplanned pregnancy. Existing percutaneous endoscopic gastrostomy tube feeding, alongside high-calorie drinks and intravenous dextrose during labour, managed the risks of hypoglycaemia and lactic acidosis. Metabolic parameters were regularly monitored and fortnightly growth scans were assessed for macrosomia. Allopurinol was continued throughout the pregnancy to reduce the risk of hyperuricaemia. MDT management optimised maternal and fetal care throughout pregnancy and labour, resulting in a successful vaginal delivery.

A 22-year-old woman was presented to the emergency department of the tertiary care centre with abdominal pain, continuous dribbling of urine and haematuria for 3 days. She had a history of obstructed labour 4 days ago, which was managed at a peripheral centre leading to the vaginal delivery of a

Objectives : To compare a perinatal outcome in breech presentation depending on different modes of vaginal breech delivery (VBD). Material and methods : Over the course of 13 years (2005–2018), perinatal outcome of newborns was compared among 98 singleton pregnancies (64 term pregnancies and 34 preterm pregnancies) completed with VBD divided into six groups depending on the mode of delivery used (Bracht, Muller, Thiessen, classical arm release, Mauriceau-Levret-Veit-Smellie (MLVS), and Vermelin´s spontaneous vaginal delivery). Also, maternal demographic parameters were observed. Results : Of 98 singleton pregnancies, the most frequently used mode was Thiessen (35.71%), followed by MLVS technique (25.51%), Bracht (22.45%), Vermelin (13.27%), classical arm release (2.04%) and Muller (1.02%). Newborns with Apgar score ≤ 7 at 5 min. were transferred to the neonatal intensive care unit (NICU), which included 15.31% of newborns (total 15 newborns: 1 term and 14 preterm newborns). The incidence of episiotomy was 63.27%. Seventy-point five percent of women included in the study were ≤ 35 years of age, and 37.76% were multiparas. Delivery was induced in 7.14% cases. Conclusions : Less- traumatizing actions during VBD have less harmful consequences and better perinatal outcome. Lower Apgar score was noted with the aggressiveness of the mode of VBD.

This study aimed to assess the validity and reliability of the Turkish version of the Women’s Perception of Respectful Maternity Care Scale. This methodological, cross-sectional study was conducted between December 2020 and July 2021. The sample of the study consisted of 259 women who had vaginal birth and gave birth to a healthy baby with normal birth weight. Data analysis and evaluation were performed using factor analysis, Cronbach’s alpha, split-half, item-total score correlation, Hotelling T2, Tukey’s test and ceiling and floor effect of the scale. The scale consists of 19 items and three sub-dimensions. The scales explained 76.04 percent of the total variance. In both exploratory and confirmatory factor tests, the overall factor loading was greater than 0.30. In the confirmatory factor analysis, all the goodness-of-fit indexes were greater than 0.90, and the root mean square error of approximation was less than 0.08. The Cronbach’s alpha coefficient of the scale was 0.96, with Cronbach’s alpha values ranging between 0.88 and 0.95 for the subscales. In conclusion, this scale can be used by nurses, midwives and other health professionals as a valid and reliable measurement tool to evaluate women’s perception of respectful maternity care. © 2022 Taylor & Francis Group, LLC.

Background: The preference for mode of childbirth by women is emerging as a global subject of interest to many researchers, especially with the steady increase in caesarean section (CS) rates with some countries exceeding the world health organization (WHO) recommended rate. This study explored the preferences of mode of childbirth and associated factors among pregnant women in Ghana. Methods: A cross-sectional study was conducted among pregnant women at tertiary hospital in Ghana. Descriptive analysis and multivariate logistic regression were performed. Results: Among the 415 pregnant women included, 357(86.0%) and 58(14.0%) preferred vaginal delivery and CS respectively. Majority (26%) attributed their preference for vaginal delivery to its being the natural way of childbirth. The most common reason why women preferred to deliver by CS was mainly influenced by medical indication such as doctors’ remarks. Significant determinants influencing preference for CS were previous childbirth [aOR:0.21, 95%CI (0.05, 0.91)], previous caesarean [aOR:20.08, 95%CI (7.73, 52.19)] and urban settlement [aOR:2.51, 95%CI (1.01, 6.29)] Conclusion: There was a clear preference for vaginal birth by pregnant women although a significant proportion preferred caesarean birth. Integration of women’s preferred mode of childbirth into the clinical decision with appropriate counselling is recommended to improve women’s pregnancy and childbirth experiences. Keywords: Caesarean section; mode of childbirth; Vaginal Delivery.

Study Objective : Assess the acceptability, expulsion and continuation rates, satisfaction, and complications associated with post-placental intrauterine device insertion (PPIUDI) in Brazilian adolescents Design : prospective cohort Setting : a single public, tertiary, teaching hospital Participants : Adolescents (≤ 19 years) giving birth by vaginal delivery or cesarean section Intervention : Post-placental IUD insertion (PPIUDI) Main Outcome Measures : Primary outcomes were PPIUDI acceptability, expulsion, continuation, and user satisfaction. Secondary outcomes were changes in menstrual bleeding and pain, infection, uterine perforation, and repeat pregnancy up to 12 months after PPIUDI Results : 294 of 1710 adolescents delivered during the study period accepted PPIUDI (acceptability 17.2%). There were no cases of infection or uterine perforation among the 91 adolescents who completed the 12 months follow-up. Overall expulsion rate was 28.6% and most cases (54%) occurred in the first six weeks after insertion. At 12 months, 85.7% of users were satisfied with the method and continuation rate was 69.2%. At the end of 12 months, there were no repeat pregnancies among the adolescents who remained with the device in place Conclusion : PPIUDI can be an effective and safe method to reduce repeat unplanned pregnancies in adolescents who have just given birth.

Objective: To describe the type of milk used to feed infants seen in private pediatric practices in Brazil. To evaluate the relationship between breastfeeding, type of delivery, and history of prematurity. Methods: This is a cross-sectional and observational study that included 4929 infants in the first year of life seen in private pediatric practices in the five geographic regions of Brazil. Mothers provided information about the type of milk used by their infant, the type of delivery (vaginal or cesarean), and whether the birth was premature. Results: Breastfeeding was the only source of milk for 56.1% (1546/2755) of infants in the first six months of life and 32.9% (716/2174) in the second. Of the infants who received other types of milk besides breastfeeding, there was a predominance of infant formula in 98.6% and 93.8% of the infants, respectively, in the first and in the second six months of life. Whole cow's milk was used by 0.7% (20/2755) of infants in the first six months and by 4.1% (90/2174) of infants in the second (p < 0.001). In the first six months of life, breastfeeding as the only type of milk was associated with vaginal delivery (OR = 1.79; p < 0.001) and not having a history of prematurity (OR = 2.48; p < 0.001). Conclusion: Breastfeeding was the only milk source for more than half of infants before 180 days of life. Birth by cesarean section and history of prematurity were negatively associated with breastfeeding as the only source of milk used in infant feeding.

Tranexamic acid (TA) has been proposed for preventing or treating primary postpartum haemorrhage (PPH), which is the leading cause of maternal morbidity and mortality worldwide. We conducted a systematic literature search to the TA role in managing PPH in vaginal and caesarean delivery. Twenty-seven randomised controlled trials (RCTs) (33,302 women) were identified. Three RCTs investigated TA for preventing PPH after vaginal delivery and 22 after caesarean section. None demonstrated a preventive effect on secondary clinical outcomes related to blood loss. Two trials evaluated TA for treating PPH after vaginal and caesarean delivery. Only the WOMAN trial showed that 1 g of TA is effective. In conclusion, TA is considered useful and is recommended or advised for treating PPH. Conversely, available evidence on the prophylactic role is still limited, and this use is not supported. Further investigation is recommended. In this regard, stronger and more reliable outcomes than blood loss should be considered.

Objective: Induction of labor (IOL) is one of the most widely used obstetric interventions. However, one-fifth of IOLs result in Cesarean section (CS). We aimed to assess maternal and fetal characteristics that influence the likelihood of CS following IOL, according to the indication for CS. Methods: This was a secondary analysis of pooled data from four randomized controlled trials, including women undergoing IOL at term who had a singleton pregnancy and an unfavorable cervix, intact membranes and the fetus in cephalic presentation. The main outcomes of this analysis were CS for failure to progress (FTP) and CS for suspected fetal compromise (SFC). Restricted cubic splines were used to determine whether continuous maternal and fetal characteristics had a non-linear relationship with outcome. Optimal cut-offs for those characteristics with a non-linear pattern were determined based on the maximum area under the receiver-operating-characteristics curve. Adjusted odds ratios (aOR) were computed, using multivariable logistic regression analysis, for the associations between optimally categorized characteristics and outcome. Results: Of a total of 2990 women undergoing IOL, 313 (10.5%) had CS for FTP and 227 (7.6%) had CS for SFC. The risk of CS for FTP was increased in women aged 31–35 years compared with younger women (aOR, 1.51 (95% CI, 1.15–1.99)), in nulliparous compared with parous women (aOR, 8.07 (95% CI, 5.34–12.18)) and in Sub-Saharan African compared with Caucasian women (aOR, 2.09 (95% CI, 1.33–3.28)). Higher body mass index (BMI) increased incrementally the risk of CS for FTP (aOR, 1.06 (95% CI, 1.04–1.08)). High birth-weight percentile was also associated with an increased risk of CS due to FTP (aOR, 2.66 (95% CI, 1.74–4.07) for birth weight between the 80.0th and 89.9th percentiles and aOR, 4.08 (95% CI, 2.75–6.05) for birth weight ≥ 90th percentile, as compared with birth weight between the 20.0th and 49.9th percentiles). For CS due to SFC, higher maternal age (aOR, 1.09 (95% CI, 1.05–1.12)) and BMI (aOR, 1.05 (95% CI, 1.03–1.08)) were associated with an incremental increase in risk. The risk of CS for SFC was increased in nulliparous compared with parous women (aOR, 5.91 (95% CI, 3.76–9.28)) and in South Asian compared with Caucasian women (aOR, 2.50 (95% CI, 1.23–5.10)). Birth weight < 10.0th percentile increased significantly the risk of CS due to SFC (aOR, 1.93 (95% CI, 1.22–3.05)), as compared with birth weight between the 20.0th and 49.9th percentiles. Bishop score did not demonstrate a significant association with the risk of CS for FTP or for SFC. Conclusions: In women undergoing IOL, maternal age, BMI, parity, ethnicity and birth-weight percentile are predictors of CS due to FTP and of CS due to SFC, but the direction and magnitude of the associations differ according to the indication for CS. These characteristics should be considered in combination with the Bishop score to stratify the risk of CS for different indications in women undergoing IOL.

Objective Uterine artery embolization is an attractive option for the management of postpartum haemorrhage, however it is not available in every hospital. We compared the clinical characteristics and haemodynamic state of patients with postpartum haemorrhage, before and after helicopter transfer to a tertiary hospital for possible uterine artery embolization. We also analysed whether the type of treatment could modify the outcome. Study design: Between 1999 and 2019 in Switzerland, we retrospectively found 82 consecutive patients with postpartum haemorrhage who were transferred by a physician-staffed helicopter emergency medical service to the tertiary hospital for potential uterine artery embolization. The collected data included the type of delivery, estimated blood loss, shock index and blood lactate levels before transfer and at destination, uterine artery embolization rate and hospital mortality rate. Our primary outcome was to describe the clinical characteristics, outcomes and haemodynamic state of the patients with postpartum haemorrhage before and after helicopter transfer. Our secondary outcome was to report the treatments performed at the tertiary hospital. The collected data were analysed with Stata version 14 (Stata Corporation, College Station, TX, USA). Continuous data are compared by using the Student's t-test or the Mann-Whitney U test, as appropriate. Results We included 69 patients. Postpartum haemorrhage occurred after vaginal delivery in 38 cases (55%). Blood loss prior to transfer exceeded 2 L in 34% of cases. The median shock index was 1 (IQR 0.8 to 1.1) before transfer and 0.9 (IQR 0.8 to 1.1) after transfer (p=0.41). The median lactate level was 2.9 mmol/L (IQR 2.1 to 6.8) before, and 2.1 mmol/L (IQR 1.55 to 3.5) after transfer (p=0.90). Forty-four patients underwent uterine artery embolization (64%), with an overall success rate of 93%. One patient died (1.4%), from a haemorrhagic shock of abdominal origin. Conclusions Interhospital helicopter transfer of patients with postpartum haemorrhage to a tertiary hospital seems to be safe in our setting, despite a significant proportion of patients exhibiting signs of haemodynamic instability. Decision criteria would be helpful to better guide choices regarding the transfer of patients with postpartum haemorrhage.

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 P 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.

Background Postpartum urinary retention (PUR) may lead to bladder neuromuscular damage and subsequently voiding dysfunction. However, the literature regarding the incidence of and risk factors for PUR remains unclear. Moreover, previously reported studies are limited to small sample sizes. Thus, this study aimed to assess the incidence of and risk factors for overt PUR after vaginal delivery. Methods This retrospective case-control study included all primiparas who delivered vaginally between July 1, 2017, and June 30, 2019, at our institution. The case group comprised 677 women diagnosed with overt PUR who required catheterisation after delivery. The control group comprised 677 women without overt PUR randomly selected in a 1:1 ratio matched for date of delivery and who delivered immediately after each woman with overt PUR to minimise the impact of variations over time in obstetric practice. Univariate and multivariate logistic regression analyses were performed to investigate the factors associated with overt PUR. Results Of the 12,609 women included in our study, 677 were diagnosed with overt PUR (incidence 5.37%). Univariate analysis identified epidural analgesia, episiotomy, perineal tears, instrument-assisted delivery, duration of labour stage, intrauterine operation, and vulvar oedema as risk factors for PUR. Multivariate logistic regression identified epidural analgesia (odds ratio [OR] = 1.41, 95% confidence interval [CI]: 1.11–1.79, P = 0.005), vulvar oedema (OR = 6.92, 95% CI: 4.65–10.31, P P = 0.002), episiotomy (OR = 1.37, 95% CI: 1.02–1.84, P = 0.035), and second-degree perineal tear (OR = 3.42, 95% CI: 2.37–4.94, P Conclusions PUR was highly associated with epidural analgesia, forceps delivery, vulvar oedema, episiotomy, and second-degree perineal tears. More attention should be paid to women at high risk to reduce the incidence of PUR.

Objectives Pregnancy and vaginal delivery are risk factors for pelvic floor dysfunction. Abdominal binder use may increase intraabdominal pressure, affecting pelvic floor healing or function in recently traumatized postpartum pelvic floor muscle. This study assesses the prevalence of postpartum abdominal binder use, timing, and reasons for use. Methods In this cross-sectional observational survey study, women who underwent a vaginal delivery at our institution were enrolled. Participants were excluded if they did not speak Spanish or English. Participants were recruited on the postpartum unit. Data were deidentified and analyzed as appropriate for each variable. Results In total, 673 surveys were completed. Seven were excluded because they had cesarean deliveries. The average age was 26 years. Median gravidity and parity were 2 and 2. In total, 549 women (82%) planned to wear an abdominal binder postpartum. In all, 335 women provided a specific time when they would start use: 240 women (71%) would start at ≤2 days postpartum, 60 women (18%) would start at 3 to 7 days postpartum, and 35 women (11%) would start after 1 week postpartum. Common reasons reported for use included appearance, support, pain, swelling, weight loss, and recommendation. Conclusions Among women delivering at our institution, planned abdominal binder use postvaginal delivery is common. The reasons cited include health and desire to return to prior body shape. The effects of using an abdominal binder in the postpartum period are unknown. More research is needed to better elucidate how increased postpartum intraabdominal pressure affects healing in traumatized pelvic floor muscles.

Purpose This study sought to evaluate whether or not the sonographic measurement of the inferior vena cava (IVC) diameter predicts severe bleeding in women with postpartum hemorrhage (PPH). It further compared the efficacy of the IVC diameter, shock index, and serum lactate levels in this prediction. Methods This prospective study included female patients with ≥500 mL of bleeding after vaginal delivery between September 1, 2019 and May 31, 2021. The IVC diameter during inspiration (IVCmin) and expiration (IVCmax), shock index and serum lactate levels of the patients were measured. The patients were divided into two groups according to the postpartum vaginal blood loss [non-severe PPH and severe PPH (SPPH)]. After multivariate logistic regression analysis revealed the significant parameters, we constructed the receiver operating characteristic (ROC) curves to determine their power in predicting SPPH. Results Of the 201 patients included in the study, SPPH developed in 21.4% of the population, while non-severe PPH occurred in 78.6%. The area under the curve (AUC) values ​​of shock index, lactate, IVCmin and IVCmax for SPPH prediction were 0.772, 0.791, 0.851 and 0.874, respectively. According to the ROC analysis, at the cut-off value of 7.3 mm, IVCmax had 90.7% sensitivity and 70.8% specificity in predicting SPPH. IVCmax was independently associated with SPPH (Odds ratio: 0.74, 95% CI: 0.63–0.86). Conclusion We found that the ultrasonographic measurement of IVC diameter is more valuable than the shock index and lactate parameters in the early detection of SPPH. Therefore, IVC diameter may be a useful prognostic marker for SPPH.

Coronary events in pregnancy are a rare but growing cause of maternal morbidity and mortality. Pregnancy presents unique challenges across a broad spectrum of disciplines and requires a multidisciplinary approach to optimize maternal and fetal outcomes. The early involvement of the “cardio-obstetrics” team in pre-pregnancy counselling, the antenatal period, delivery and post-partum is vital to ensuring better outcomes for patients at high risk of coronary pathology. The overall risk for coronary events complicating pregnancy is increasing due to a number of factors including advancing maternal age and increases in traditional cardiac risk factors; contributing to higher rates of maternal morbidity and mortality. The majority of pregnant women experiencing a coronary event do not have prior coronary disease, and the pathological mechanisms involved are predominantly non-atherosclerotic. Diagnosis and management should follow standard guideline-based practices for acute coronary syndrome (ACS), including the use of diagnostic coronary angiography to guide percutaneous intervention when needed. Management of ACS should not be delayed to facilitate delivery, which can proceed following stent implantation and dual antiplatelet therapy. The timing and mode of delivery should be based on assessment of maternal and fetal status, but vaginal delivery is preferred when possible. This review aims to provide an overview of the major etiologies, risk factors, diagnosis and management strategies for patients at risk of or presenting with coronary events in pregnancy.

Purpose To evaluate the efficacy of superselective transcatheter arterial embolization (TAE) for intractable postpartum hemorrhage (PPH) due to genital tract trauma (GTT) after vaginal delivery. Methods We evaluated 27 patients who underwent TAE for intractable PPH due to GTT after vaginal delivery at our institution between January 2008 and December 2020. Patients were divided into two groups according to TAE procedure; TAE performed as close as possible to the bleeding point, at least more peripherally than the second branch of the anterior division of the internal iliac artery, was defined as superselective TAE (S-TAE). TAE performed from the proximal segment of the internal iliac artery was defined as proximal TAE (P-TAE). Patient characteristics, pre-procedural contrast-enhanced computed tomography (CE-CT), procedure details, technical/clinical success, and complications were evaluated separately for the S-TAE and P-TAE groups. Results The combined technical/clinical success rate was 92%. No major procedure-related complications were seen (mean follow-up: 6.12 ± 3.93 days). The combined technical/clinical success rate of S-TAE was 100% and of P-TAE was 67% (p = 0.04). S-TAE was performed more frequently in patients with pre-procedural CE-CT (p = 0.01) and use of permanent embolic materials (p = 0.003). Conclusion S-TAE is safe and effective for intractable PPH due to GTT. Pre-procedural CE-CT may be useful for detecting the culprit artery and be helpful in performing S-TAE.

Introduction and hypothesis This study was aimed at exploring the mediating role of the prolonged second stage of labor (PSSL) in the association between delivery mode and urinary incontinence (UI) among postpartum women in Shandong, China. Methods A cross-sectional study involving postnatal women from the Women's Pelvic Floor Functional Health Center in Shandong, China, was conducted. An electronic questionnaire was used to collect the data between June 2020 and February 2021. UI was assessed using the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF). Logistic regression and multiple linear regression were employed to explore the association among delivery mode, PSSL, and UI, and the mediating role of PSSL. Results Among the total of 5,586 postpartum women included in this study, the prevalence of UI was 13.3%. Among the 742 patients with UI, the prevalence of stress urinary incontinence (78.3%) was greater than urge urinary incontinence (8.6%), mixed urinary incontinence (9.3%), and others (3.8%). After adjusting for controlling variables, delivery mode was found to be significantly associated with PSSL, whereby women with vaginal delivery were more likely to be in PSSL, and women with PSSL had a higher probability of suffering from UI. PSSL played a partial mediating effect in delivery mode and UI. Conclusions This study provided evidence that the effect of delivery mode on UI was partially mediated by PSSL among postpartum women in Shandong, China. Strategies to prevent PSSL should be actively adopted to reduce the risk of UI in women.

Objective: The aim of the study was to investigate the impact of intrapartum antibiotic treatment (IAT) on the compositional development of gut microbiota in healthy term infants. Study Design: A case-control study of 24 infants exposed to and 24 matched infants not exposed to IAT was conducted. All subjects were born by vaginal delivery at term and breastfed. None of the infants received antibiotics during the immediate neonatal period. Fecal samples were obtained at the ages of 1 and 6 months. The composition of the intestinal microbiota was assessed by 16S rRNA gene sequencing. Results: IAT was associated with reduced microbial richness but not diversity at 1 month of age. Furthermore, the relative abundances of Clostridiaceae and Erysipelotrichaceae were significantly altered in infants exposed to IAT as compared to nonexposed infants at 1 month of age. The observed deviations in gut microbiota composition between infants exposed and not exposed to IAT diminished by the age of 6 months. Conclusions: IAT is associated with short-term perturbations in the gut microbiota development in healthy term, vaginally delivered, breastfed infants. The composition of the gut microbiota is mostly restored by the age of 6 months.

OBJECTIVE To assess the cost-effectiveness of vaginal misoprostol (PGE1; 25 μg) compared with a slow-release dinoprostone (PGE2) pessary (10 μg) for labor induction due to an unfavorable cervix at term. METHODS We used data from an open-label multicenter, randomized non-inferiority trial that recruited women for whom labor was induced for medical reasons. The incremental cost-effectiveness ratio was assessed from the payer's perspective, with the focus on inpatient care costs and using the cesarean deliveries avoided (CDA) rate as the primary analysis and the rate of vaginal delivery within 24 h (VD24) as the secondary analysis. RESULTS Analyses were based on 790 women in each group. Differences between treatment arms were the mean cost per patient of €4410 and €4399, a CDA rate of 80.1% and 77.9% and a VD24 rate of 46.1% and 59.4% for dinoprostone and misoprostol, respectively. Dinoprostone is not cost-effective according to the CDA rate and misoprostol was either a cost-effective or a dominant strategy according to the VD24. CONCLUSION Misoprostol and dinoprostone have equal cost management with mixed efficacy according to the clinical outcome used. Finally, misoprostol may be an attractive option for hospitals as the price is lower and it is easier to use. TRIAL REGISTRATION ClinicalTrials.gov: NCT01765881.

Fournier’s gangrene (FG), a necrotizing fasciitis of the genital and perineal region, is a serious and debilitating multi-infective pathological condition. More commonly seen in adults, its occurrence in neonates is uncommon. We share our experience with neonatal FG (NFG), highlighting potential factors which may predispose neonates to it. Ours is a five year retrospective review of cases of NFG in our service. Data obtained included health facility of birth, mode of delivery, symptoms and duration, investigation results, treatment and outcome. Sixteen neonates were included, comprising 13 males (M:F = 4.3:1). Fourteen were delivered outside our centre; breech vaginal delivery, hot water massaging and application of native concoctions were common. All were treated with antibiotics and wound debridement, but five (37.5%) died.NFG is not that rare in our service. Early recognition is imperative to reduce mortality. Neonates delivered by breech vaginally may be particularly at risk.

This study examined the associated factors (i.e., obstetric and maternal-newborn factors) related to cumulative incidence of urinary incontinence and changes in urinary incontinence during pregnancy and the first year postpartum. This prospective, longitudinal, within-subject study included 501 women who completed the Incontinence Questionnaire-Urinary Incontinence Short Form during pre-pregnancy, early pregnancy, mid-pregnancy, and late pregnancy and at five time points during the first year postpartum. Data were analyzed by multivariate logistic regression, McNemar’s and analysis of variance (ANOVA) tests. According to the multivariate analysis, the gestational week and number of previous vaginal deliveries increased the risk of cumulative incidence of urinary incontinence (CIUI) during pregnancy (both p

Pubovisceral muscle (PVM) injury during a difficult vaginal delivery leads to pelvic organ prolapse later in life. If one could address how and why the muscle injury originates, one might be able to better prevent these injuries in the future. In a recent review we concluded that many atraumatic injuries of the muscle-tendon unit are consistent with it being weakened by an accumulation of passive tissue damage during repetitive loading. While the PVM can tear due to a single overstretch at the end of the second stage of labor we hypothesize that it can also be weakened by an accumulation of microdamage and then tear after a series of submaximal loading cycles. We conclude that there is strong indirect evidence that low cycle fatigue of PVM passive tissue is a possible mechanism of its proximal failure. This has implications for finding new ways to better prevent PVM injury in the future.

OBJECTIVE: To determine the predictors of mortality following early rescue surfactant therapy in preterm babies with respiratory distress syndrome. STUDY DESIGN: Prospective cohort study enrolling babies between 28 weeks to 34 weeks with respiratory distress syndrome requiring early rescue surfactant therapy. For statistical analysis babies were further divided into two subgroups: survivors and non-survivors. Maternal and neonatal variables were compared between the two groups to find out the predictors of mortality. RESULTS: Out of total 110 babies, 72 (65.45%) survived. The mean birth weight and mean gestational age of the study population was 1614.36 (±487.86) g and 31.40 (±2.0)1 weeks, respectively. Birth weight

Background The effect of epidural/spinal anesthesia during labor on breastfeeding is unclear. Few studies had assessed whether or how medically assisted delivery (operative vaginal delivery or unscheduled cesarean birth) plays a mediating role. We aimed to examine whether the relationship between using epidural/spinal anesthesia and breastfeeding is mediated by increased medically assisted delivery among healthy nulliparous women. Methods A secondary, cross-sectional analysis was conducted using US birth certificate data from 2016 (n = 381 199). Logistic regression was used to examine associations between factors. Structural equation modeling (SEM) was used to analyze the model fit of the path models and to quantify the direct, indirect, and total effect of anesthesia on breastfeeding at discharge, considering medically assisted delivery as a mediator. Results Women who were administered epidural/spinal anesthesia were more likely to experience medically assisted delivery (adjusted odds ratio [AOR]: 95% confidence interval [CI] 3.01 (2.91-3.12)) and less likely to be breastfeeding at discharge (0.95 [0.92-0.98]). Operative vaginal and unscheduled cesarean deliveries were significantly associated with nonbreastfeeding at discharge (0.81 [0.77-0.84] and 0.81 [0.79-0.84], respectively). SEM revealed excellent model fit for our model. The indirect effect was significant (β = -0.038; 95% CI, -0.043 to -0.033), as was the total effect (β = -0.038; 95% CI, -0.043 to -0.033). Conclusions Epidural/spinal anesthesia is associated with nonbreastfeeding at discharge, mediated through medically assisted delivery. Health care providers should consider these risks and provide adequate support to help all parents attain their breastfeeding goals.

OBJECTIVE To analyze the effect and efficiency of the characteristics of PHC facilities' structures and the work process of PHC teams on late neonatal mortality (LNM). METHODS This ecological time-series study adopted 3.764 Brazilian municipalities as analysis units. The independent variables were sorted into three hierarchical levels and four blocks. The distal level consisted of economic and demographic variables; the intermediate level comprised health coverage and demand for services; and the proximal level included structure and work process. The dependent variable was LNM. A linear mixed-effects regression analysis with a hierarchical approach was performed, estimating the crude (β) and adjusted (alpha = 5%) regression coefficients. Data involution analysis and municipalities were the decision-making unit according to their strata. RESULTS LNM was directly associated with the number of live births and unemployment rate. LNM was inversely associated with the year, per capita income, the community health worker's strategy coverage, vaginal delivery, household visits, and available vaccines. In the 2002-2014 period, the number of municipalities efficient in reducing LNM dropped from 38 to 27. In 2014, a more significant investment occurred in the number of vaginal deliveries in almost all strata to make inefficient municipalities efficient. CONCLUSION FOR PRACTICE The deaths of children aged 7-28 days are affected by the characteristics of the PHC structure and work process.

Objective: To characterize the influence of birthplace on outcomes of patients with gastroschisis admitted to three hospitals in a state in Brazil’s southeastern region, according to condition inborn (born in a reference center) or outborn (born outside the reference center). Methods: Retrospective multicenter cohort study of patients with gastroschisis. The sample size utilized was of patients admitted in three hospitals with a diagnosis of gastroschisis ICD 10 Q79.3 between January 2000 to December 2018. Patients were divided into two groups, inborn and outborn. Characteristics of prenatal, perinatal and postoperative were compared using statistical tests. The level of significance adopted was P-value < 0.05. Results: In total, 144 cases of gastroschisis were investigated. The outborn patients group had higher rates of absence of antenatal diagnosis (p = 0.001), vaginal delivery (p = 0.001), longer time between birth and abdominal wall closure surgery (p = 0.001), to silo removal (p = 0.001), to first enteral feeding (p = 0.008), for weaning from mechanical ventilation (p = 0.034), used less peripherally inserted central catheter (PICC) and required more venous dissections (p = 0.001), and lower mean of serum sodium (p = 0.015). There were no differences in mortality rates and length of hospital stay between the inborn and outborn groups. Conclusion: Although outborn patients with gastroschisis were less likely to have an antenatal diagnosis and were more prone to a longer time to undergo surgical and feeding procedures, and to spend more time in mechanical ventilation, these disadvantages seemed not to reflect on the death rate and the length of hospital stay of patients from this group.

Background Umbilical artery thrombosis is a rare complication of pregnancy strongly associated with poor fetal and perinatal outcomes, such as intrauterine asphyxia, fetal growth restriction, and stillbirth. Its pathogenesis remains unclear, and there is the added challenge of selecting an appropriate delivery time to achieve excellent neonatal outcomes. Methods Our Hospital is a critical maternal rescue center with approximately 7000 births annually. We present a series of 8 cases of umbilical artery thrombosis diagnosed at the hospital between Apr 1, 2018, and Jan 31, 2020. We identified the cases through a keyword search of the maternity and pathology information management systems. Results Three patients were diagnosed with a transabdominal ultrasound scan and hypoxia on fetal heart monitoring. All three patients had emergency cesarean section delivery. Four patients were observed closely for 5 to 13 weeks from initial detection by an ultrasound scan to delivery. Only one patient was diagnosed after vaginal delivery by Hematoxylin-eosin staining of umbilical cord sections. Seven patients had deliveries by cesarean section, and one patient had a vaginal delivery. All infants were born alive. Conclusions Umbilical artery thrombosis is a challenging and rare condition that can occur at different gestational ages, especially when diagnosed in the third trimester and accompanied by fetal growth restriction. Consequently, these patients require close monitoring of umbilical blood flow and fetal growth and intervention at the appropriate time to achieve an optimal outcome.

A nationwide shortage of oxytocin in Canada resulted in a temporary switch from oxytocin to carbetocin for all postpartum women at our institution. This change offered a unique opportunity to conduct a pragmatic comparative assessment of the efficacy of carbetocin and oxytocin.In a retrospective before-after study, we reviewed the medical records from 641 women in the carbetocin group and 752 women in the oxytocin group . The standard carbetocin dosing was 100 µg iv following vaginal and intrapartum Cesarean delivery, while for elective Cesarean delivery it was 50 µg, with an additional 50 µg if required. The standard oxytocin dosing was 5 IU iv followed by 2.4 IU·hrThe incidence of additional uterotonic use was not different between the carbetocin and oxytocin groups (12.0% vs 8.8%; P = 0.05; odds ratio, 1.39; 95% confidence interval, 0.97 to 2.00). The incidence of postpartum hemorrhage was higher in the carbetocin group than in the oxytocin group (10.3% vs 6.6%; P = 0.01). Blood transfusion was more common in the carbetocin group (1.4% vs 0.3%; P = 0.02).There was no difference in the use of additional uterotonics when carbetocin or oxytocin were used in a cohort of women undergoing vaginal deliveries and both elective and emergency Cesarean deliveries.RéSUMé: OBJECTIF: Une pénurie nationale d’ocytocine au Canada a entraîné l’utilisation temporaire de la carbétocine en remplacement de l’ocytocine pour toutes les femmes en post-partum dans notre établissement. Grâce à cette substitution, nous avons bénéficié d’une occasion unique de mener une évaluation comparative pragmatique de l’efficacité de la carbétocine et de l’ocytocine. MéTHODE: Dans une étude rétrospective avant-après, nous avons examiné les dossiers médicaux de 641 femmes dans le groupe carbétocine et de 752 femmes dans le groupe ocytocine. Le dosage standard de carbécotine était de 100 μg iv après un accouchement vaginal et pendant un accouchement par césarienne intrapartum, tandis que pour un accouchement par césarienne élective, le dosage était de 50 μg, avec 50 μg supplémentaires au besoin. Le dosage standard d’ocytocine était de 5 UI iv suivi de 2,4 UI·h

OBJECTIVE To examine the simultaneous effect of high-volume Foley catheter (HVFC) (60 ml) and vaginal misoprostol on labor induction in nulliparous women. METHODS A randomized, double-blind, controlled trial was conducted among nulliparous post-date (>40 weeks) pregnant women between June and December 2019. At enrollment 100 women were randomized into each group (either HVFC and vaginal misoprostol or low-volume Foley catheter [LVFC] [30 ml] and vaginal misoprostol), for labor induction. Demographic and clinical data were collected at enrollment and delivery. RESULTS Women in the HVFC group had statistically significantly shorter induction to delivery interval (median 860 min, interquartile range [IQR] 840-940 min vs. 1160 min, IQR 1080-1320 min, P

OBJECTIVE To estimate the association of the weight difference between the index trial of labor after cesarean (TOLAC) sonographic estimated fetal weight (sEFW) and prior delivery birth weight with TOLAC success rate among women with previous labor dystocia and no prior vaginal delivery. METHODS A retrospective cohort study including all women with prior cesarean for labor dystocia and no prior vaginal delivery undergoing TOLAC during between March 2011 and June 2020 with a sEFW within 1 week from delivery. RESULTS Overall, 168 women were included, of those 107 (63.7%) successfully delivered vaginally. The mean sEFW and mean birth weight were lower in the TOLAC success group (P = 0.010 and P = 0.013, respectively). The rate of higher sEFW in the current delivery compared with the previous delivery did not differ between study groups. The rate of higher TOLAC birth weight was lower in the TOLAC success group (odds ratio 0.30; 95% confidence interval 0.15-0.58). In multivariable regression analysis, maternal age older than 30 years, induction of labor, and higher birth weight were independently negatively associated with TOLAC success (adjusted odds ratio [95% confidence interval]: 0.27 [0.10-0.70], 0.27 [0.08-0.90], and 0.43 [0.19-0.94]; P = 0.008, P = 0.034, and P = 0.035, respectively). CONCLUSIONS sEFW characteristics did not predict the success or failure of TOLAC among women with prior labor dystocia and no previous vaginal delivery.

Non-invasive vaginal rejuvenation with radiofrequency (RF) and lasers devices have gained popularity, but well-designed studies confirming their effectiveness are lacking. The aim of this study was to compare the efficacy and safety of a multipolar RF and pulsed electromagnetic field-based device (PEMF) versus sham for vaginal laxity. Thirty-two premenopausal females with ≥ 1 vaginal delivery and self-reported vaginal laxity were randomized into 2 groups: active (RF + PEMF) and sham. Both groups received 3 vaginal treatments at 3-week interval. The Vaginal Laxity Questionnaire (VLQ), perineometer measurements, and Brink score were conducted at baseline, 4, and 12 weeks after treatments. Pre and post-treatment vaginal histology, Female Sexual Function Index (FSFI), subjects’ satisfaction, pain, and adverse events were assessed. The active group VLQ scores increased and were significantly better than the sham group (p 4) versus 12% in the sham group (p = 0.054). In the active group, all domains of perineometer measurements and Brink scores (p p p p = 0.014). Histology after RF + PEMF treatments demonstrated neocollagenesis, neoelastogenesis, and neoangiogenesis. In conclusion, combination RF + PEMF therapy was safe, improved vaginal laxity, strengthened pelvic floor muscles, and improved female sexual function for at least 12-week post-procedures with confirmed histological improvements. This study was registered on the Thai Clinical Trials Registry, TCTR20200803002 on 2020–07-30 “retrospectively registered.”

Aim In Japan, the criteria of the latent and active phases of the first stage of labor have not been decided. The Japan Society of Obstetrics and Gynecology (JSOG) Perinatal Committee conducted a study to construct a spontaneous labor curve in order to determine the point of onset of the active phase. Methods The participants were women who had spontaneous deliveries at four health facilities in Japan between September 1, 2011, and September 31, 2019. Spontaneous delivery was defined as the spontaneous onset of labor at term (37 weeks, 0 days to 41 weeks, 6 days) with vaginal delivery of a mature fetus in a cephalic position without uterotonic agents or epidural analgesia. The time points for each "cm" of dilation were collected starting from the time of full dilation retrogradely. The relationship between time since labor onset and cervical dilation was expressed as a curve using a smoothing B-spline. Results A total of 4215 primiparous and 5266 multiparous women were included in this study. The spontaneous labor curve showed that in both primiparous and multiparous women, labor progress was slow until 5 cm cervical dilation, accelerating between 5 and 6 cm dilation, and steadily progressed after 6 cm dilation. Conclusion We propose that the active phase of the first stage of labor be defined as starting at 5 cm dilation of the cervix, and that it be divided into an acceleration phase (5-6 cm dilation) and a maximal phase (>6 cm dilation).

This study investigated the role of cesarean section (CS) in mortality and morbidity of very-low-birth-weight infants (VLBWIs) weighing less than 1500 g. This nationwide prospective cohort study of the Korean Neonatal Network consisted of 9,286 VLBWIs at 23–34 gestational weeks (GW) of age between 2013 and 2017. The VLBWIs were stratified into 23–24, 25–26, 27–28 and 29–34 GW, and the mortality and morbidity were compared according to the mode of delivery. The total CS rate was 78%, and was directly proportional to gestational age. The CS rate was the lowest at 61% in case of infants born at 23–24 GW and the highest at 84% in VLBWIs delivered at 29–34 GW. Contrary to the significantly lower total mortality (12%) and morbidities including sepsis (21%) associated with CS than vaginal delivery (VD) (16% and 24%, respectively), the mortality in the 25–26 GW (26%) and sepsis in the 27–28 GW (25%) and 29–34 GW (12%) groups were significantly higher in CS than in VD (21%, 20% and 8%, respectively). In multivariate analyses, the adjusted odds ratios (ORs) for mortality (OR 1.06, 95% CI 0.89–1.25) and morbidity including sepsis (OR 1.12, 95% CI 0.98–1.27) were not significantly reduced with CS compared with VD. The adjusted ORs for respiratory distress syndrome (1.89, 95% CI 1.59–2.23) and symptomatic patent ductus arteriosus (1.21, 95% CI 1.08–1.37) were significantly increased with CS than VD. In summary, CS was not associated with any survival or morbidity advantage in VLBWIs. These findings indicate that routine CS in VLBWIs without obstetric indications is contraindicated.

To evaluate the maternal and neonatal outcomes associated with vacuum-assisted vaginal delivery (VAVD) in a subset of parturients with congenital uterine anomalies.A retrospective database study was conducted at a single tertiary center between 2005 and 2019. Parturients with known congenital uterine anomalies who had vaginal deliveries were enrolled, whereas parturients with failed VAVD, didelphic uterus, and delivery after intrauterine fetal death were excluded. Various maternal and neonatal outcomes were compared between parturients who achieved spontaneous vaginal delivery (SVD) and those who delivered via VAVD. The maternal composite outcome was calculated for each group and included one or more of the following: post-partum hemorrhage, hemoglobin drop ≥ 4 gr/dL, blood transfusions, retained placental products, and obstetric anal sphincter injuries. Univariate analysis was performed followed by multivariate logistic regression analysis controlling for potential confounders. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated.After the application of the exclusion criteria, 332 parturients were found eligible. Of those, 289 (87%) had SVD and 43 (13%) had VAVD. VAVD was more common among primiparous parturients and epidural analgesia users. Parturients with VAVD had higher rates of third-degree perineal tear, postpartum hemorrhage, and blood transfusions. The maternal composite outcome was significantly more prevalent in the VAVD group (44.2% vs. 20.8%, p 0.01). After controlling for potential confounders, the maternal composite outcome was found to be independently associated with VAVD (aOR 2.3, 95% CI 1.10-4.60). The neonatal results were overall comparable, except for scalp trauma and Erb's palsy/clavicular fracture, which were more prevalent in the VAVD group.In a special population of parturients with congenital uterine anomalies, VAVD was found to be associated with significantly higher rates of adverse maternal outcomes and perinatal birth trauma. These findings should be presented to parturients during consultations about modes of delivery.

Purpose To evaluate the independent factors associated with the success of a trial of vaginal birth (TVB) in women with type 1 diabetes. Despite all therapeutic efforts and technological innovations, rates of caesarean sections (CS) in pregnant women with type 1 diabetes remain unchanged above 60%. Our aim was to point out influencing factors to improve the quality of antepartum counseling. Methods We performed a retrospective cohort study of 195 pregnancies with type 1 diabetes treated between 2000 and 2019. After exclusions, 118 women with near-term singleton pregnancies intended vaginal birth (TVB). Group differences between CS and successful vaginal delivery were analyzed. Multivariate logistic regression was performed by including clinical and metabolic variables to determine the independent effects on a successful vaginal delivery. Subgroup analysis for nulliparous women. Results Of 118 women with TVB, 67 (56.8%) were delivered vaginally. History of previous vaginal delivery (OR 10.29; CI 2.39; 44.30), HbA1c changes during pregnancy (per % increase; OR 0.59; CI 0.36; 0.96) and gestational weight gain (per kg; OR 0.87; CI 0.80; 0.96) were independent predictors for a successful vaginal delivery. In nulliparous women, the duration of diabetes was independently and negatively associated with vaginal delivery. Conclusion Provided data can help to improve antepartum counseling in type 1 diabetic patients. It seems that women with type 1 diabetes should avoid postponing pregnancy and childbirth.

The aim of the study was to evaluate pain following overnight osmotic cervical dilator placement for second trimester dilation and evacuation (DE).A retrospective cohort study surveyed pain and quantified prescription opioid use among 100 women who underwent overnight osmotic cervical dilator placement for DE. Participants were given opioid and non-steroidal anti-inflammatory (NSAID) prescriptions and were asked to rate their level of pain on a Likert scale (1-10). Demographic and medical information was abstracted from electronic medical records. Bivariate analyses of demographic and clinical characteristics by pain score and opioid use were conducted. Multivariate linear regression analyses were performed for pain score. A multivariate logistic regression model was fitted for factors associated with opioid use.Gestational age ranged from 14 to 23 weeks (average 19 ± 3 weeks). The mean score of worst pain experienced was 5.3 out of 10. Participants reported 3.4 h of moderate pain (4-6 out of 10) and 1.0 h of severe pain (7-10 out of 10); 54% of women took at least one opioid (mean 2.8 ± 1.5). Multivariate analysis showed that higher pain was associated with younger age (Most participants with overnight cervical dilators for DE experienced at least moderate pain and used opioid pain medication in addition to NSAIDs when available. A shared decision-making model may be appropriate for determining which patients may benefit from opioids.

Objective To evaluate the moxibustion for turning fetuses from breech to vertex presentation. Materials and Methods This was a single-center prospective study. All pregnant women carrying a fetus in breech presentation between the 32 and 35 gestational weeks were offered moxibustion application. The primary outcomes were vertex presentation at 37 weeks of gestation, vertex presentation at birth, and vaginal birth rates. A secondary analysis was performed to understand the effect of parity, type of breech presentation, body mass index (BMI), placental location, gender, and fetal birth weight on the presentation at birth. Results There were 63 cases in the study group and 245 cases in the control group. The rate of vertex presentation at term was found to be higher in the moxibustion group compared to controls (66.7 vs. 48.2%, p=0.022). There were 45 (71.4%) and 131 (53.5%) fetuses with vertex presentation at birth in the study and control groups, respectively (p=0.020). Overall, vaginal delivery rate was higher in the study group (50.8 vs. 37.1%, p=0.048). Multiparity and higher birth weight were associated with increased rates of vertex presentation in the moxibustion and control groups. Conclusion Moxibustion application increased the rate of vertex presentation at birth and also vaginal delivery rate compared with expectant management. Offering moxibustion between the 32nd and 36th week of gestation may provide women with a singleton fetus in breech presentation an opportunity for a vaginal birth.

OBJECTIVES To compare the incidence of cephalic marks in newborns exposed to operative vaginal delivery and those who are not. We examined the factors associated with alterations in neonatal well-being and with cephalic mark occurrence. METHODS Prospective study involving singleton term newborns delivered in a cephalic presentation. Newborns in the operative group were matched with newborns born on the same day without instruments required. A cephalic mark was defined as any mark or edema on the newborn's skin between 12 and 72 hours of life. Neonatal well-being was assessed by analgesic consumption, neonatal discomfort (EDIN score of 1 or more), and prolonged hospitalization (4 days or more). We compared the operative and spontaneous groups and determined the relative risk (RR) for cephalic marks. We investigated the factors associated with alterations in neonatal well-being and factors associated with cephalic mark occurrence in the case of operative delivery using multivariate logistic regression analysis. RESULTS A total of 135 newborns were included in each group. The incidence of cephalic marks was higher in the operative group (RR = 13.3 [6.0-29.5]). In case of operative delivery, cephalic marks were associated with neonatal discomfort (adjusted odds ratios [aOR] = 8.2 [2.2-30.6]) and analgesic consumption (aOR = 3.0 [1.2-7.1]). The number of cephalic marks was higher in cases with sequential use of vacuum and forceps (aOR = 3.5 [1.1-11.7]) and forceps only deliveries (aOR = 3.0 [1.1-8.1]) relative to vacuum only deliveries. CONCLUSIONS Operative delivery increases the risk of neonatal cephalic marks, which can negatively affect neonatal well-being.

Background Intra-partum cefazolin is used to prevent group B Streptococcus (GBS) vertical transmission in mothers allergic to penicillin without a history of anaphylaxis. Objectives To investigate the maternal cefazolin dose–exposure relationship and subsequent maternal and neonatal target attainment at delivery. Methods Data were obtained from 24 healthy, GBS-colonized pregnant women (20–41 years), undergoing vaginal delivery (gestational age ≥37 weeks). During labour, all women received a 2 g cefazolin IV infusion. Eight hours later, eight women received another 1 g in the event of delayed (>8 h) delivery. Next to maternal plasma concentrations (up to 10 per dosing interval, until delivery), venous and arterial umbilical cord concentrations were determined at delivery. Target attainment in maternal/neonatal plasma was set at 1 mg/L for 60% of the dosing interval (unbound cefazolin, worst-case clinical breakpoint). A population pharmacokinetic (popPK) model was built (NONMEM 7.4). ClinicalTrials.gov Identifier: NCT01295606. Results At delivery, maternal blood and arterial umbilical cord unbound cefazolin concentrations were >1 mg/L in 23/24 (95.8%) and 11/12 (91.7%), respectively. The popPK of cefazolin in pregnant women was described by a two-compartment model with first-order elimination. Two additional compartments described the venous and arterial umbilical cord concentration data. Cefazolin target attainment was adequate in the studied cohort, where delivery occurred no later than 6.5 h after either the first or the second dose. PopPK simulations showed adequate maternal and umbilical cord exposure for 12 h following the first dose. Conclusions PopPK simulations showed that standard pre-delivery maternal cefazolin dosing provided adequate target attainment up to the time of delivery.

Author(s): Mok, Thalia; Harris, Elijah; Vargas, Andres; Afshar, Yalda; Han, Christina S; Karagozian, Ann; Rao, Rashmi | Abstract: ObjectiveTo characterize respiratory emissions produced during labor and vaginal delivery vis-a-vis the potential for transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).MethodsObservational study of three women who tested negative for SARS-CoV-2 and had uncomplicated vaginal deliveries. Using background-oriented schlieren imaging, we evaluated the propagation of respiratory emissions produced during the labor course and delivery. The primary outcome was the speed and propagation of breath over time, calculated through processed images collected throughout labor and delivery.ResultsIn early labor with regular breathing, the speed of the breath was 1.37 meters/s (range 1.20-1.55 meters/s). The breath appeared to propagate faster with a cough during early labor at a speed of 1.69 meters/s (range 1.22-2.27 meters/s). During the second stage of labor with Valsalva and forced expiration, the propagation speed was 1.79 meters/s (range 1.71-1.86 meters/s).ConclusionLabor and vaginal delivery increase the propagation of respiratory emissions that may increase risk of respiratory transmission of SARS-CoV-2.

Objective Forceps delivery is associated with a higher risk of maternal birth trauma. It is speculated that it is due to sub-optimal use of forceps in inexperienced hands. The aim of this study was to determine the association between time of forceps birth and prevalence of levator avulsion over the last six decades. Study Design This was a retrospective analysis of datasets of women with a history of forceps delivery, seen at a tertiary urogynaecological centre between January 2014 and August 2018. They had undergone a standardized interview, clinical examination and four-dimensional translabial ultrasound. Archived imaging data was reviewed for levator avulsion offline at a later date, blinded against all clinical data. Associations between levator avulsion, maternal age at first vaginal birth, the weight of the first vaginally born baby, and time since forceps delivery categorised by decade were tested by univariable analysis. Factors found to be significant on univariable analysis were included in a multivariable logistic regression model to test the association between prevalence of levator avulsion and time of forceps delivery while controlling for confounders. Results In total, 2026 patients were seen during the study period. Among them 511 (25.2%) had a history of forceps delivery. Fourteen volume datasets were incomplete or missing, leaving 497 complete datasets for analysis. Mean age at presentation was 58 ± 12 years (23–91). Mean body mass index was 29 ± 6 kg/m2. Mean age at first delivery was 25 ± 5 years. Mean birth weight of the first vaginal birth was 3454 ± 557 g. 457 women (92%) had had one forceps delivery, 31 had two forceps deliveries (6%) and 9 had three forceps deliveries (2%). Mean time interval between forceps delivery and assessment was 32 ± 13 years (0.3–64.8). 229 women (46%) were diagnosed with levator avulsion. The prevalence of avulsion after forceps increased significantly from 34% to 56% between 1950 and 2017 (P = 0.04). However this difference became insignificant when controlling for maternal age at 1st vaginal delivery and birth weight. Conclusions We found no evidence of a changed prevalence of levator avulsion at forceps delivery over the last 67 years.

1. Jena Song, DO, MPH* 2. Jose Bustillo, DO* 3. Sherin Meledathu, DO* 1. *Department of Internal Medicine and Pediatrics, Newark Beth Israel Medical Center and Children’s of New Jersey, Newark, NJ A full-term, large for gestational age newborn girl, is born via vaginal delivery to a 32-year-old gravida 3, para 3 mother with a generally uncomplicated pregnancy. The pediatrics team has been called to the delivery for meconium-stained amniotic fluid. The infant does not appear to be in respiratory distress and has Apgar scores of 9 and 9 at 1 and 5 minutes, respectively. Her blood glucose level is 45 mg/dL. Upon inspection, she is noted to have a large, raised, hyperpigmented plaque covering the right side of her head, measuring 18 × 15 cm (Figs 1 and 2). This plaque is accompanied by greater than 20 other macules, patches, and plaques diffusely distributed throughout the body that are either hyper or hypopigmented, have either smooth or irregular borders, and vary in size from 0.5 to 3 cm (Fig 3). The patient also has multiple areas of blue-gray pigmented patches on her sacrum, but no sacral dimple is evident. Her neurologic examination reveals a newborn who is alert, responsive, and has normal primitive reflexes and tone for gestational age. Her head circumference is 35.5 cm (53rd percentile). No dysmorphic features are noted, and the remainder of the examination is remarkable only for a systolic heart murmur. Figure 1. Gross visualization of plaque throughout the body.

In the prospective multicenter Genesis study, we developed a prediction model for Cesarean delivery (CD) in term nulliparous women. The objective of this secondary analysis was to determine whether the Genesis model has the potential to predict maternal and neonatal morbidity associated with vaginal delivery.The national prospective Genesis trial recruited 2,336 nulliparous women with a vertex presentation between 39 + 0- and 40 + 6-weeks' gestation from seven tertiary centers. The prediction model used five parameters to assess the risk of CD: maternal age, maternal height, body mass index, fetal head circumference and fetal abdominal circumference. Simple and multiple logistic regression analyses were used to develop the Genesis model. The risk score calculated using this model were correlated with maternal and neonatal morbidity in women who delivered vaginally: postpartum hemorrhage (PPH), obstetric anal sphincter injury (OASI), shoulder dystocia, one- and five-minute Apgar score ≤ 7, neonatal intensive care (NICU) admission, cephalohematoma, fetal laceration, nerve palsy and fractures. The morbidities associated with spontaneous vaginal delivery were compared with those associated with operative vaginal delivery (OVD). The likelihood ratios for composite morbidity and the morbidity associated with OVD based on the Genesis risk scores were also calculated.A total of 1,845 (79%) nulliparous women had a vaginal delivery. A trend of increasing intervention and morbidity was observed with increasing Genesis risk score, including OVD (p 0.001), PPH (p 0.008), NICU admission (p 0.001), low Apgar score at one-minute (p 0.001) and OASI (p = 0.009). The morbidity associated with OVD was significantly higher compared to spontaneous vaginal delivery, including NICU admission (p 0.001), PPH (p = 0.022), birth injury (p 0.001), shoulder dystocia (p = 0.002) and Apgar score of7 at one-minute (p 0.001). The positive likelihood ratios for composite outcomes (where the OVD was excluded) increases with increasing risk score from 1.005 at risk score of 5% to 2.507 for risk score of50%.In women who ultimately achieved a vaginal birth, we have shown more maternal and neonatal morbidity in the setting of a Genesis nomogram-determined high-risk score for intrapartum CD. Therefore, the Genesis prediction tool also has the potential to predict a more morbid vaginal delivery.

Background Mother and newborn skin-to-skin contact (SSC) is an immediate postpartum intervention known to improve the health of newborn and mothers alike. Albeit, there is paucity of data that explored the coverage or factors associated with SSC in Nigeria. Therefore, we aimed to explore the coverage and hierarchical nature of the factors associated with SSC among women of reproductive age in Nigeria. Methods The 2018 Nigeria Demographic and Health Survey (NDHS) data was used for this study. Data on 29,992 women who had ever given birth were extracted for analysis. SSC was the outcome variable as determined by women’s report. A multivariable multilevel logistic regression model was used to estimate the fixed and random effects of the factors associated with SSC. Statistical significance was determined at p< 0.05. Results The coverage of SSC was approximately 12.0%. Educated women had higher odds of SSC, when compared with women with no formal education. Those who delivered through caesarean section (CS) had 88% reduction in SSC, when compared with women who had vaginal delivery (OR= 0.12; 95%CI: 0.07, 0.22). Women who delivered at health facility were 15.58 times as likely to practice SSC, when compared with those who delivered at home (OR= 15.58; 95%CI: 10.64, 22.82). Adequate ANC visits and low birth weight significantly increased the odds of SSC. Women from richest household were 1.70 times as likely to practice SSC, when compared with women from poorest household (OR= 1.70; 95%CI: 1.04, 2.79). There was 65% reduction in SSC among women with high rate of community non-use of media, when compared with women from low rate of community non-use of media (OR= 0.35; 95%CI: 0.20, 0.61). Conclusion SSC coverage was low in Nigeria. Moreover, individual, household and community level factors were associated with SSC. More enlightenment should be created among women to bring to limelight the importance of SSC specifically to newborn’s health.

Background Women with inflammatory bowel disease [IBD] have an increased risk for caesarean section [CS], but perineal obstetric outcomes, which may have significant consequences for women with IBD, have not been previously studied. Method Maternal outcomes in singleton pregnancies of IBD and non-IBD patients [2014–2018] in a single centre were studied. Results In 31 528 non-IBD and 179 IBD patients delivery by CS was more likely in IBD patients (p = 0.0021, relative risk [RR] 1.45, confidence interval [CI] 1.16–1.81). Elective CS in IBD patients occurred in 40% for IBD indications, all in accordance with current international guidelines. Perineal trauma, including tears involving the anal sphincter, were equally uncommon in IBD [2.23%] and non-IBD patients [3.40%; p = 0.35, RR 0.64, CI 0.24–1.68]. Of the four IBD patients with clinically significant tears, none had pelvic floor dysfunction or incontinence at follow-up in a specialist postnatal perineal trauma clinic. One IBD patient who had a clinically non-significant second-degree perineal tear reported incontinence a year after giving birth. Previous perianal disease was not associated with significant perineal trauma. Conclusion The low rate of perineal trauma is reassuring for promotion of vaginal delivery in most IBD patients. In those who experienced tears involving the anal sphincter no continence issues occurred. Women with IBD having a greater incidence of delivery by CS was only partially explained by IBD indications.

OBJECTIVE To evaluate the delivery rate in the occiput posterior position according to the result of manual rotation performed in the case of persistent occiput posterior position. Secondary objectives were perinatal outcomes. METHODS This was a prospective cohort study conducted in two French tertiary care units. All women with a singleton pregnancy after 37 weeks of gestation with a fetus in persistent occiput posterior position and an attempt of manual rotation were included. The main outcome was the occiput position at delivery. The secondary outcomes were duration of labor, mode of delivery, and perineal tears. Two groups were compared according to the result of manual rotation. RESULTS In total, 460 women were included, with a manual rotation success of 62.4%. The success was significantly associated with a decrease in occiput posterior position at vaginal delivery (1.4% vs 57.2%, P
