Childbirth related perineal trauma is extremely common after vaginal birth. Limited evidence suggests that subsequent complications such as wound infection or dehiscence occur frequently, yet interventions aimed at improving outcomes in this large group of women remain scarce. Here, we review the different types of tear after childbirth, their prevalence, risk factors, complications and best management, as well as exploring the evidence underlying current recommendations and practice.

Background: Birth preparedness and complication readiness is a holistic approach that empowers mothers and families with the knowledge, attitude, and resources to alleviate potential challenges during childbirth. Despite its benefits, husbands' participation in maternal care differs significantly between countries and regions. There is a lack of previous studies that look at husbands' responses to birth preparedness and complication readiness in the research area. Thus, the primary goal of this study is to find out how husbands who have wives with infants under 12 months old feel about birth preparation, readiness for problems, and its associated factors. Methods: A community-based cross-sectional study design was conducted from May 30 to July 29, 2022. Simple random sampling was employed to select 499 husbands. An interviewer-administered, structured, and pretested questionnaire was used to collect the data. Data entry and analysis were performed using Epi Data version 4.6 and SPSS version 25, respectively. We used multivariable logistic regression to find statistically significant factors. P-values less than 0.05, 95% confidence intervals, and adjusted odds ratios are used to declare statistical significance. The findings were shown in figures, tables, and text. Results: The study found that 55.9% (95% CI: 51.4 to 61.4%) of husbands responded to birth preparedness and complication readiness. This response was significantly associated with being employed (AOR = 3.7, 95% CI: 2.27–5.95), engaging in self-business (AOR = 5.3, 95% CI: 2.34–12.01), having wives who delivered in health facilities (AOR = 7.1, 95% CI: 3.92–12.86), accompanying wives for antenatal care (AOR = 2.2, 95% CI: 1.39–3.56), possessing good knowledge of danger signs during labor (AOR = 2.0, 95% CI: 1.08–3.74) and the postnatal period (AOR = 7.1, 95% CI: 3.14–16.01). Interestingly, residents living near a health facility (AOR = 0.6, 95% CI: 0.39–0.97) were less likely to respond. Conclusion: The present study found that nearly 6 out of 10 husbands actively responded in terms of birth preparedness and complication readiness. While husbands in this study showed some involvement in birth preparedness and complications, it is good when compared to studies carried out nationally. To improve this, educating husbands by focusing on the danger signs and their role in childbirth is recommended. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to examine maternal and neonatal factors in cesarean deliveries due to dystocia, including cephalopelvic disproportion, latent‐phase prolongation, and fetal malposition or malpresentation. Additionally, we sought to compare the differences between the dystocia subgroups. Method and Materials: This retrospective case–control study included women who delivered between January 2010 and June 2021 after 37 weeks of pregnancy and underwent abdominal‐pelvic CT scans within 5 years before and after delivery. Neonatal factors were extracted from medical charts immediately after delivery. Results: Among the 292 women studied, those with cesarean deliveries for dystocia were older (mean ± SD, 34.2 ± 4.27 vs. 32.2 ± 3.8, p‐value = 0.002), had higher pre‐pregnancy BMI (22.7 ± 3.67 vs. 21.4 ± 3.48, p‐value = 0.012) and term‐BMI (27.4 ± 3.72 vs. 25.9 ± 3.66, p‐value = 0.010), shorter interspinous distance (ISD, the distance between ischial spine) (10.8 ± 0.76 vs. 11.2 ± 0.85 cm, p‐value = 0.003), and longer head circumference (HC) (35 ± 1.47 vs. 34.4 ± 1.36 cm, p‐value = 0.003) compared to those who had vaginal deliveries. Univariate logistic regression for dystocia revealed associations between HC/maternal height and HC/ISD ratios (OR, 2.02 [95% confidence interval, CI, 1.4 ~ 2.92], 12.13 [3.2 ~ 46.04], respectively). Multivariate logistic analysis indicated that maternal age, ISD, and HC were significant factors for dystocia (OR, 1.11 [95% CI, 1.01 ~ 1.21], 0.49 [0.26 ~ 0.91], 1.53 [1.07 ~ 2.19], respectively). The subgroup with latent‐phase prolongation exhibited the lowest birthweight/term‐BMI ratio (124 ± 18.8 vs. 113 ± 10.3 vs. 134 ± 19.1, p‐value = 0.013). Conclusion: The HC/ISD ratio emerged as a crucial predictor of dystocia, suggesting that reducing term‐BMI could potentially mitigate latent‐phase prolongation. Further research assessing the maternal mid‐pelvis during pregnancy and labor is warranted, along with efforts to reduce BMI during pregnancy. [ABSTRACT FROM AUTHOR]

Introduction and Hypothesis: Obstetric anal sphincter injuries (OASIs) complicate 5.8% of vaginal deliveries. Our objective was to assess if the primary delivery provider, a nurse-midwife versus physician obstetrician, is associated with OASIs. Methods: We performed a secondary analysis of the Consortium of Safe Labor, a multicenter, retrospective cohort study. Included were nulliparous women with singleton, vaginal delivery at ≥37 weeks from 2002 to 2008. Women were excluded if delivery was complicated by shoulder dystocia or from sites without midwife deliveries. Student's t-tests, chi-squared analysis, and Fisher's exact test were used as appropriate. Multivariable logistic regression and propensity score-matching analyses were performed. Results: Of 228,668 births at 19 sites, 2735 births from 3 sites met the inclusion criteria: 1551 physician and 1184 midwife births. Of all births, 4.2% (n = 116) were complicated by OASIs. Physician patients were older, more often White, privately insured, with higher BMI, more medical co-morbidities, and labor inductions/augmentations. Midwife patients had higher fetal gestational age and infant birth weights (all p < 0.05). OASIs were more common in physician compared to midwife births (5.9% vs. 2.0%, p < 0.0001). This difference persisted in multivariable logistic regression. OASIs were 2.4 (95%CI 1.5–3.9) times more likely with physician delivery when controlling for maternal heart disease, episiotomy, increasing maternal age, decreasing maternal BMI, non-White race, and increasing birthweight. The AUC was 0.78. With propensity score matching, OASI rates remained higher amongst physician births (6.6% vs. 1.8%, p < 0.0001; aOR 3.8 (95%CI 2.0–7.1)). Conclusion: OASIs were more common in physician compared to midwife deliveries even when controlling for other associated factors. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to investigate whether time of birth, unit volume, and staff seniority impact the incidence of maternal complications in deliveries ≥34 + 0 gestational weeks. Methods: We conducted a population‐based cross‐sectional study of 87 065 deliveries occurring between 2004 and 2015 in ten public hospitals in Styria, Austria. A composite adverse maternal outcome measure of uterine atony, postpartum hysterectomy, postpartum bleeding, impaired wound healing, postpartum infections requiring antibiotic treatment, sepsis, or maternal death was used to compare outcomes by time of birth, unit volume, and staff seniority. Based on delivery data, generalized estimating equations (GEEs) were used to calculate the risk of maternal adverse outcomes. Results: Maternal adverse events occurred in 1.33% of deliveries. Incidence of maternal adverse events was highest for units with >1000 deliveries (adjusted OR 1.40; CI 95%: 1.16–1.69) and higher for perinatal centers (adjusted OR 1.35; CI 95%: 1.15–1.57) compared with reference units (500–1000 deliveries/year). Delivery during the daytime compared with the afternoon and nighttime did not affect the incidence of maternal complications (P = 0.765 and P = 0.136, respectively). Compared with resident‐guided deliveries, the odds ratio for an adverse event was the same when a consultant attended the delivery (adjusted OR 1.13; CI 95%: 0.98–1.30) but lower in deliveries managed by midwives only (adjusted OR 0.21; CI 95%: 0.07–0.64). Conclusion: Procedures performed during the night shift were not associated with increased complication rates. Delivery volume and high‐volume centers were associated with the highest risk of maternal complications, and units with 500–1000 deliveries per year were the lowest. With increasing odds of pregnancy risks, these results change, and delivering in a high‐volume center becomes at least as safe as delivering in a smaller unit. [ABSTRACT FROM AUTHOR]

To determine whether the maternal plasma concentrations of cytokines are higher in pregnant women with postpartum hemorrhage (PPH) compared to pregnant women without PPH. A retrospective case-control study included 36 women with PPH and 72 matched controls. Cases and controls were matched for gestational age at delivery, labor status, delivery route, parity, and year of sample collection. Maternal plasma samples were collected up to 3 days prior to delivery. Comparison of the plasma concentrations of 29 cytokines was performed by using linear mixed-effects models and included adjustment for covariates and multiple testing. A false discovery rate adjusted p-value <0.1 was used to infer significance. Random forest models with evaluation by leave-one-out and 9-fold cross-validation were used to assess the combined value of the proteins in predicting PPH. Concentrations of interleukin (IL)-16, IL-6, IL-12/IL-23p40, monocyte chemotactic protein 1 (MCP-1), and IL-1β were significantly higher in PPH than in the control group. This difference remained significant after adjustment for maternal age, clinical chorioamnionitis, and preeclampsia. Multi-protein random forest proteomics models had moderate cross-validated accuracy for prediction of PPH [area under the ROC curve, 0.69 (0.58–0.81) by leave-one-out cross validation and 0.73 (0.65–0.81) by 9-fold cross-validation], and the inclusion of clinical and demographic information did not increase the prediction performance. Pregnant women with severe PPH had higher median maternal plasma concentrations of IL-16, IL-6, IL-12/IL-23p40, MCP-1, and IL-1β than patients without PPH. These cytokines could serve as biomarkers or their pathways may be therapeutic targets. – Pregnant women with severe PPH had higher maternal plasma concentrations of IL-16, IL-6, IL-12/IL-23p40, MCP-1, and IL-1β than patients without PPH. – Maternal plasma cytokines could serve as biomarkers, or their pathways may be therapeutic targets in PPH.

Background/aims: To evaluate maternal birth and neonatal outcomes among women with gestational diabetes mellitus (GDM), but without specific medical conditions and eligible for vaginal birth who underwent induction of labour (IOL) at term compared with those who were expectantly managed. Materials and methods: Population‐based cohort study of women with GDM, but without medical conditions, who had a singleton, cephalic birth at 38–41 completed weeks gestation, in New South Wales, Australia between January 2010 and December 2016. Women who underwent IOL at 38, 39, 40 weeks gestation (38‐, 39‐, 40‐induction groups) were compared with those who were managed expectantly and gave birth at and/or beyond the respective gestational age group (38‐, 39‐, 40‐expectant groups). Multivariable logistic regression analysis was used to assess the association between IOL and adverse maternal birth and neonatal outcomes taking into account potential confounding by maternal age, country of birth, smoking, residential location, residential area of socioeconomic disadvantage and birth year. Results: Of 676 762 women who gave birth during the study period, 66 606 (10%) had GDM; of these, 34799 met the inclusion criteria. Compared with expectant management, those in 38‐ (adjusted odds ratio (aOR) 1.11; 95% CI, 1.04–1.18), 39‐ (aOR 1.21; 95% CI, 1.14–1.28) and 40‐ (aOR 1.50; 95% CI, 1.40–1.60) induction groups had increased risk of caesarean section. Women in the 38‐induction group also had an increased risk of composite neonatal morbidity (aOR 1.10; 95% CI, 1.01–1.21), which was not observed at 39‐ and 40‐induction groups. We found no difference between groups in perinatal death or neonatal intensive care unit admission for births at any gestational age. Conclusion: In women with GDM but without specific medical conditions and eligible for vaginal birth, IOL at 38, 39, 40 weeks gestation is associated with an increased risk of caesarean section.

Objective  This study aimed to estimate whether there is an association between the predicted probability of vaginal birth after cesarean delivery (VBAC) and the occurrence of obstetric anal sphincter injuries (OASIS). Study Design  This was a single-site retrospective cohort study of all women with a singleton vaginal birth after a previous cesarean section between January 2011 and December 2016. Women were divided into four ordinal groupings by the predicted probability of achieving vaginal birth after cesarean using the Maternal–Fetal Medicine Units Network VBAC calculator (less than 41%, 40.1–60%, 60.1–80%, and greater than 80%). The primary outcome was OASIS, defined as a 3rd or 4th degree perineal laceration. Bivariable and multivariable analyses were used to examine the association between predicted VBAC probability and OASIS. Results  In total, 1,411 women met inclusion criteria and 73 (5.2%) sustained OASIS. The median predicted probability of VBAC was lower in women with OASIS compared with those without OASIS (60% [interquartile range {IQR}: 48–70%] vs. 66% (IQR: 52–80%), p  = 0.02]. On bivariable and multivariable logistic regression, predicted probability of VBAC was associated with increased odds of OASIS (less than 41% probability: adjusted odds ratio [aOR]: 3.18, 95% confidence interval [CI]: 0.90–11.21; 41–60% probability: aOR: 3.76, 95% CI: 1.34–10.57; 61–80% probability aOR: 3.47, 95% CI: 1.25–9.69) relative to women with a predicted probability of VBAC of greater than 80%. Conclusion  Having a lower predicted probability of VBAC is associated with an increased risk of OASIS at the time of a VBAC relative to those with greater than 80% predicted probability. Incorporation of this aspect of maternal morbidity may inform risk-stratification at the time of trial of labor after cesarean, as well as the choice of performing an operative vaginal delivery. Key Points Predicted probability of VBAC is associated with OASIS. Low predicted probability of VBAC is associated with increased odds of OASIS. Forceps delivery was associated with the highest odds of OASIS. [ABSTRACT FROM AUTHOR]

Aim: Assisted reproductive technology (ART) is gaining popularity worldwide. However, it is associated with increased incidence of velamentous umbilical cord insertion (VCI) in the placenta, resulting in adverse perinatal outcomes. This study aimed to identify the risk factors that might affect the incidence of VCI in pregnancies after ART treatment. Methods: We retrospectively analyzed the records of 906 singleton pregnancies via ART; all women delivered in our facility. Three ART‐related variables and infant sex were examined: (1) fertilization method (conventional in vitro fertilization or intracytoplasmic sperm injection), (2) type of embryo at the time of transfer (fresh or frozen–thawed), (3) developmental stage of embryo at the time of transfer (cleavage stage or blastocyst), and (4) infant sex (male or female). Logistic regression analysis was used to assess the impact of these variables on the incidence of VCI. Results: Of 906 cases, 55 had VCI (incidence rate, 6.1%). After adjusting for potential confounders, blastocyst stage of development (adjusted odds ratio [aOR]: 4.3, 95% confidence interval [CI]: 1.9–12.7) and female sex (aOR: 2.2, 95% CI: 1.2–3.9) emerged as independent risk factors for the development of VCI. The fertilization method and type of embryo at the time of transfer did not affect the incidence of VCI. Conclusions: Blastocyst stage of development and female sex pose a higher risk for developing VCI. Thus, more attention should be paid to pregnancies achieved by blastocyst and with a female fetus to detect VCI proactively and safeguard the health of both mother and fetus/neonate.

Background: Induction of labour (IOL) and caesarean section (CS) rates continue to increase in Australia, New Zealand and globally. There is evidence that CS rates are decreased in the context of medically indicated and elective IOL; therefore, the emerging concept of using IOL as means of preventing CS warrants investigation. Aims: To assess obstetricians' opinions of elective IOL at 39 weeks gestation, its feasibility, generalisability and utility as a means of preventing CS in Australia and New Zealand. Materials and Methods: A de‐identified cross‐sectional survey was distributed electronically to all Fellows and trainees of The Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG). The survey was voluntary and distributed with the approval of the RANZCOG Continuing Education Committee. The survey addressed opinions relating to rates of and indications for IOL, the perceived validity of those indications and explored the acceptability of using a screening tool to predict women at increased risk of intra‐partum CS and tailoring obstetric management to include the option of IOL at 39 weeks gestation. Results: The overall response rate was 34% (492/1423) (including trainees) and the response rate was 53% (394/750) for currently practising obstetricians. The majority (90%) of responders agreed on medical and clinical indications for IOL. There was no consensus on the validity of IOL if a woman were at apparent high risk of intra‐partum CS; however, 81% (360/443) of clinicians would be interested in a tool that could predict those women at risk. Conclusions: There is heterogeneity of obstetrician's beliefs on using IOL at 39 weeks as a mechanism to reduce the CS rate. [ABSTRACT FROM AUTHOR]

Background: Tears are common after vaginal birth, and different impact factors are known. However, the impact of tears from a previous birth to the tears of a subsequent birth is unknown. Therefore, we aimed to evaluate the distribution of birth tear patterns according to the sustained tears in a previous birth, in addition to other impact factors. Methods: In a retrospective cohort study, we evaluated all women up to parity 4 with subsequent vaginal, singleton births of vertex presentation at ≥37 + 0 gestational weeks between 1/2005 and 12/2016. Their tears were grouped into tear patterns and were analyzed by parity. Tear patterns in the subsequent births were analyzed in association to the patterns of the previous births and impact factors were evaluated. Results: We counted 4017 births in 1855 women [P1: 1368 (34.1%), P2: 1730 (43.1%), P3: 741 (18.4%), P4: 178 (4.4%)]. The frequency of tears and episiotomies decreased with higher parity, whereas the frequency of intact perineum increased. Twenty-eight different unique tear patterns were found. We could show that birth tear patterns changed with increasing parity and were associated with sustained tears in a previous birth. In addition, some impact factors on tear patterns could be identified. Conclusion: The distribution of the single tear types is in accordance with the current literature. However, it is new that distinct tear patterns are associated to sustained tear patterns of previous births. Furthermore, we demonstrated some weak associations of tear patterns to certain impact factors, such as more episiotomies, low-grade perineal or vaginal tears isolated or in combination with other tears with increasing fetal weight and head circumference in the higher parities, and with a longer duration of the second stage and the pushing phase in lower parities.

Objective  This study aimed to examine whether labor before cesarean affects the risk of placenta accreta spectrum (PAS) disorders in a subsequent pregnancy. Study Design  This is a secondary analysis of the Cesarean Registry, a prospective cohort study of women undergoing cesarean between 1999 and 2002. Women with one prior cesarean with known indications, which were categorized as likely associated with labor (labored cesarean) versus likely not associated with labor (unlabored cesarean), were included. Primary outcome was PAS disorder. Results  Of 34,224 women, 60% had a "labored cesarean" and 40% had an "unlabored cesarean." Women with prior unlabored cesarean were more likely to have subsequent PAS disorder compared with women with a prior labored cesarean after adjusting for confounders (0.28 vs. 0.13%; adjusted odds ratio: 2.03; 95% confidence interval: 1.22–3.38). Conclusion  Prior unlabored cesarean is associated with an increased risk of PAS disorders in a subsequent pregnancy. This association may aid in risk stratification in women with suspected PAS disorders and help counsel about risks associated with cesarean on maternal request. [ABSTRACT FROM AUTHOR]

Idiopathic thrombocytopenic purpura is a relatively rare complication occurring in pregnancy, with the potential for serious maternal and fetal outcomes. Rarely, the poor response to established first-line therapies results in consideration of second-line therapies, which may have poorly understood risks to the fetus. We report two women with severe idiopathic thrombocytopenic purpura during pregnancy unresponsive to corticosteroids and intravenous immunoglobulin who were treated with romiplostim, a thrombopoietin receptor agonist. One woman with chronic idiopathic thrombocytopenic purpura had a partial response to romiplostim and suffered a post-partum haemorrhage related to uterine atony. The second woman developed severe idiopathic thrombocytopenic purpura in pregnancy and initially responded well to romiplostim. However, a lower segment Caesarean section was performed at 37 weeks for pre-eclampsia. The newborn suffered from severe idiopathic thrombocytopenic purpura and a grade 1 cerebral haemorrhage requiring intravenous immunoglobulin and platelet transfusions. Romiplostim might be a useful therapy for severe idiopathic thrombocytopenic purpura in pregnancy but requires further study. [ABSTRACT FROM AUTHOR]

Objective: To select a group at high risk of placenta accreta spectrum disorders (PAS) based on the data of serum screening in the first trimester. Methods: A retrospective analysis of 48 patients with abnormal placental location (AP), including placenta previa (PP) only (n = 23) and PP and PAS (n = 25), was performed. Additionally, the AP group was divided depending on the blood loss volume: not higher than 1000 mL (LBL) (n = 29) and higher than 1000 mL (HBL) (n = 19); diagnostic term of PAS by ultrasound, data pregnancy-associated plasma protein-A (РAРР-A) and free β subunit of human chorionic gonadotropin (free β-hCG) multiple of median (MоM) at 11+0–13+6 weeks of gestation were evaluated. Serological markers were compared with the data of 39 healthy pregnant women with scar after previous cesarean section and normal placental location (control). Results: The mean gestation at diagnostic term of PAS was 29 weeks. PAPP-Р MоM [mean (M) ± standard deviation (SD)] was: in controls, 1.07 ± 0.47; in the AP group, 1.59 ± 0.24; in PP, 1.91 ± 1.52; in PAS, 1.30 ± 0.85; in LBL, 1.37 ± 1.20; in HBL, 1.91 ± 1.24. The difference between control/AP, control/PP, control/PAS, PP/PAS, control/LBL, control/HBL and LBL/HBL was Р = 0.256, 0.145, 0.640, 0.311, 0.954, 0.025 and 0.09, respectively. Free β-hCG MoM (M ± SD) was: in controls, 1.08 ± 0.69, in AP, 1.31 ± 0.96; in PP, 1.46 ± 0.19; in PAS, 1.16 ± 0.65; in LBL, 1.30 ± 0.06; in HBL, 1.32 ± 0.78. Comparison of free β-hCG AP with controls and between subgroups did not reveal a significant difference. Conclusion: Underestimation of PAS risk factors in pregnant women with AP leads to late diagnostics of pathology only in the third trimester. The assessment of the РAРР-A level in the first trimester may be helpful for the early prognosis of pathological blood loss at delivery for pregnant women with AP and for forming the high-risk group for PAS.

Aim: To evaluate obstetric outcomes in embryo transfer (ET) during estrogen with progestin hormone replacement therapy (HRT) cycles using assisted reproductive technology (ART). Methods: Of the 118 singleton pregnancies conceived with ART and delivered between January 2015 and December 2017, we reviewed the data of 87 cases that had information on HRT at the time of ET. Data on pregnancy outcomes included the presence of small for gestational age fetuses, hypertensive disorders of pregnancy, placenta previa (including low‐lying placenta), placental abruption and placenta accreta spectrum (including placenta accreta, placenta increta and placenta percreta). We investigated the relationship between HRT cycles and adverse placental outcomes (placenta accreta spectrum, placental abruption, placenta previa, hypertensive disorders of pregnancy and small for gestational age fetuses). We then analyzed the associations that correlated with adverse placental outcomes. Results: Patients with ET during HRT cycles were more likely to have placenta accreta spectrum. During the study period, 87 out of 118 singleton live births using ART had information on HRT (60 HRT cycles and 27 ovulation cycles). The incidence of placenta accreta spectrum was significantly higher in the HRT cycle group than in the ovulation cycle group (HRT cycle, 31.7% [19 of 60] vs ovulation cycle, 7.4% [2 of 27]; P < 0.01). Conclusion: The obstetric outcomes occurring in pregnancies involving HRT use may differ among ET cycles. ET during HRT cycles were associated with adverse obstetric outcomes due to placenta accreta spectrum. The potential interaction between HRT cycles and adverse placental events is novel and warrants further investigation. [ABSTRACT FROM AUTHOR]

Objective: Placenta accreta is an abnormal implantation of the placenta, which often leads to postpartum bleeding. Cesarean hysterectomy is the most recommended procedure. However, more-conservative management is currently being investigated to maintain future fertility or uterus. This study was designed to describe a new systematic surgical technique for preserving the uterus while removing the abnormal placenta. Additional goals were to determine the characteristics and outcomes of this procedure. Materials and Methods: This approach involved corporal incision, hypogastric artery ligation, and using an ovarian and pericervical uterine tourniquet. Fifty-nine patients were enrolled in this cross-sectional study, with a median age of 29, ranging from ages 25 to 37. Eighteen of these patients (30.5%) were in their second pregnancy and had only 1 previous childbirth, 38 patients (64.4%) were in their third pregnancy, and 3 (5.1%) were in their forth pregnancy. Results: All patients had successful uterine preservation after the removal of their abnormal placentae. Median bleeding volume was 550 (range: 300–1200) mL. Bladder injury occurred in 1 patient. Conclusions: Using this systematic surgical technique and temporarily devascularizing the patients' uteri, it was possible to remove the abnormal placentae—without incurring massive bleeding—and then to reconstruct the uteri.

Objective Despite heterogeneity among Pacific Islanders, most studies aggregate them regardless of origin. Thus, limited information is available about perinatal outcomes among various subgroups of Pacific Islanders in the United States, including immigrants from the Republic of the Marshall Islands. We sought to evaluate perinatal outcomes among Marshallese women. Methods We conducted a cross-sectional study of women with at least one singleton live birth between 1997 and 2013 in two Arkansas counties using birth certificate data from the Arkansas Department of Health. Unadjusted and adjusted prevalence ratios (PR) and 95% confidence intervals (CI) were calculated from modified Poisson regression models. Results Of the 91,662 singleton births in both counties during the study period, 2488 were to Marshallese women. In adjusted analyses, Marshallese women had higher prevalence of "other medical risk factors" (PR = 1.47; 95% CI 1.30, 1.65) than NH White women. Marshallese women had higher rates of precipitous labor and fetal distress during labor compared to NH White women (PR = 2.65; 95% CI 2.22, 3.17 and 1.89; 95% CI 1.62, 2.21, respectively). Marshallese were also more likely to have tocolysis (PR = 1.43; 95% CI 1.16, 1.76), forceps (PR = 1.68; 95% CI 1.16, 2.43) or vacuum (PR = 1.89; 95% CI 1.60, 2.22) used in delivery and cesarean section (PR = 1.13; 95% CI 1.01, 1.27). Marshallese infants had higher rates of anemia (PR = 3.10; 95% CI 2.01, 4.77), birth injury (PR = 2.13; 95% CI 1.50, 3.03), assisted ventilation < 30 min (PR = 2.11; 95% CI 1.64, 2.71), preterm birth (PR = 1.67; 95% CI 1.50, 1.83), and small-for-gestational age (PR = 1.25; 95% CI 1.12, 1.39) than NH White infants. Conclusions Marshallese women and infants had higher rates of adverse perinatal outcomes compared to their NH White counterparts. Additional studies are needed to determine if perinatal outcomes among the Marshallese differed from other Pacific Islander subgroups. [ABSTRACT FROM AUTHOR]

Objective  Placenta accreta is a feared pathology, in part, because prenatal diagnosis is imperfect. It is not known whether clinical risk factors or sonographic features equally predict the entire graded pathological spectrum of placental overinvasion disease nor whether clinical outcomes differ along the spectrum. Study Design  We conducted a mixed methods retrospective study of a cohort of women screened sonographically for placenta accreta, cross-referenced against cases identified by pathological diagnosis (N  = 416). Demographic, diagnostic, and outcome information were compared across the spectrum of invasive placentation: percreta, increta, accreta, and focal accreta not requiring hysterectomy. The t -test, chi-square, Mann–Whitney, and Kruskal–Wallis tests were used for statistical analysis across groups. Results  As the depth of invasion decreased, risk factors for placental overinvasion were less common, especially placenta previa and previous cesarean. There was also reduced anticipation by sonographic examination of the placenta. Rates of adverse outcomes were lower among women with focal accreta compared with those with deeper invasion. Conclusion  As the depth of invasion decreases, clinical risk factors and sonographic evaluation are less reliable in the antenatal prediction of placenta accreta. The potential for unanticipated morbidity underscores the need for improved diagnostic tools for placenta accreta spectrum. [ABSTRACT FROM AUTHOR]

Abstract The term abnormal labour, or labour dystocia, refers to a situation when there is slow or no progress in labour. Abnormal labour is associated with an increased risk of adverse perinatal outcomes for both mother and baby which include bleeding, sepsis, operative vaginal and abdominal delivery, as well as newborn admission to the neonatal unit. To understand what an abnormal labour is, it is important that the reader understands what is meant by normal labour first. This will help to understand how normal labour can incrementally drift into the sphere of "abnormal or dysfunctional labour". The article will also address how to manage abnormal labour.

Objective  To assess the risk factors, adverse obstetrical outcomes, and recurrence risk associated with pathologically diagnosed occult placenta accreta. Study Design  This was a retrospective observational study of clinically adherent placentas requiring manual extraction that underwent pathological examination. Cases were defined as those with histological evidence of placenta accreta, and controls were defined as those without accreta. All subsequent pregnancies were evaluated to determine the recurrence risk of occult accreta in future pregnancies. Results  Of 491 women with clinically adherent placentas, 100 (20.1%) with a pathological diagnosis of occult accreta were compared with 391 (79.9%) without occult accreta. In bivariable analysis, risk factors associated with occult accreta included a history of previous cesarean (19 vs. 10.7%; p  = 0.03) and prior uterine surgery (35 vs. 19.7%; p  = 0.001). Adverse obstetrical outcomes were more common in women with occult accreta including postpartum hemorrhage (59 vs. 31.7%; p  < 0.001) and peripartum hysterectomy (21 vs. 0.3%; p  < 0.001). In 130 subsequent pregnancies, there was an increased risk of retained placenta (42.9 vs. 19%; p  = 0.04) and recurrence of occult accreta (29.6 vs. 6.8%; p  = 0.05). Conclusion  Occult accreta is associated with an increased risk of hemorrhagic morbidity and recurrence of morbidly adherent placenta in subsequent pregnancies. [ABSTRACT FROM AUTHOR]

Objective: The aim of this article is to describe a hysterectomy technique for managing selected difficult cases of placenta accreta. Background: Cesarean hysterectomy for placenta accreta is associated with a significant amount of maternal morbidity. Intraoperative hemorrhage and urinary-tract injury are some of the more-frequent complications encountered. Most women with placenta accreta have undergone at least one prior cesarean delivery, increasing the risk of adhesions and scar tissue. Results and Conclusions: The current authors' technique for an extended hysterectomy in selected high-risk cases of placenta accreta/percreta is designed to reduce the risk of hemorrhage and urinary tract injuries.

Sheehan’s syndrome remains a frequent obstetric complication with an uncertain pathophysiology. We aimed to assess the incidence of hypopituitarism (≥2 hormonal axis impairment) within the first six postchildbirth months and to determine the existence of anti-pituitary antibodies. From 2015 to 2017, adult pregnant women, who developed moderate to severe postpartum hemorrhage (PPH), were consecutively included in the study. Pituitary function was assessed 4 and 24 weeks after PPH. At the end of the study, anti-pituitary antibodies were assessed. Twenty women completed the study. Mean age was 26.35 (±5.83) years. The main etiology for severe PPH was uterine atony (65%) which resulted mostly in hypovolemic shock grades III-IV. Within the first four weeks after delivery, 95% of patients had at least one hormonal pituitary affected and 60% of the patients fulfilled diagnostic criteria for hypopituitarism. At the end of the study period, five patients (25%) were diagnosed with hypopituitarism (GH and cortisol axes affected). Anti-pituitary antibodies were negative in all patients. At 6 months follow-up, one in every four women with a history of moderate-to-severe PPH was found with asymptomatic nonautoimmune-mediated hypopituitarism. The role of autoimmunity in Sheehan’s syndrome remains uncertain. Further studies are needed to improve the remaining knowledge gaps. [ABSTRACT FROM AUTHOR]

Background: Placenta percreta is the morbidly adherent form of all the placental invasion abnormalities. The pathology that underlies placenta percreta is poorly understood. Aims: To compare the levels of circulating vascular endothelial growth factor, placental growth factor and soluble fms-like tyrosine kinase 1 in pregnant women with placenta percreta to a control group. Study Design: Case-control study. Methods: Twenty-two women who underwent caesarean section due to placenta percreta and 22 women who underwent caesarean section for other obstetric reasons were included in this study. The diagnosis of placenta percreta was defined as extreme trophoblastic invasion involving serosa of the uterus. Venous blood samples were collected for biochemical comparison of circulating vascular endothelial growth factor, placental growth factor and soluble fms-like tyrosine kinase 1 from all pregnant women. Results: Women with placenta percreta were significantly older, had higher gravidity, received more frequent antenatal steroids and blood transfusions and delivered at an earlier gestational age when compared to the control group. In women with placenta percreta, preoperative circulating levels of vascular endothelial growth factor, placental growth factor and soluble fms- like tyrosine kinase 1 were lower than the controls (p<0.001, p<0.001 and p<0.05, respectively). While the postoperative levels of vascular endothelial growth factorand soluble fms-like tyrosine kinase 1 levels were higher in placenta percreta (p=0.001 and p<0.001, respectively), placental growth factor levels were similar in both groups. Conclusion: The findings of this study suggest that a decrease in vascular endothelial growth factor, placental growth factor and soluble fms-like tyrosine kinase 1 levels may be related to placenta percreta etiopathogenesis.

Importance: Clinicians have been urged to delay the use of obstetric interventions (eg, labor induction, cesarean delivery) until 39 weeks or later in the absence of maternal or fetal indications for intervention.Objective: To describe recent trends in late preterm and early term birth rates in 6 high-income countries and assess association with use of clinician-initiated obstetric interventions.Design: Retrospective analysis of singleton live births from 2006 to the latest available year (ranging from 2010 to 2015) in Canada, Denmark, Finland, Norway, Sweden, and the United States.Exposures: Use of clinician-initiated obstetric intervention (either labor induction or prelabor cesarean delivery) during delivery.Main Outcomes and Measures: Annual country-specific late preterm (34-36 weeks) and early term (37-38 weeks) birth rates.Results: The study population included 2,415,432 Canadian births in 2006-2014 (4.8% late preterm; 25.3% early term); 305,947 Danish births in 2006-2010 (3.6% late preterm; 18.8% early term); 571,937 Finnish births in 2006-2015 (3.3% late preterm; 16.8% early term); 468,954 Norwegian births in 2006-2013 (3.8% late preterm; 17.2% early term); 737,754 Swedish births in 2006-2012 (3.6% late preterm; 18.7% early term); and 25,788,558 US births in 2006-2014 (6.0% late preterm; 26.9% early term). Late preterm birth rates decreased in Norway (3.9% to 3.5%) and the United States (6.8% to 5.7%). Early term birth rates decreased in Norway (17.6% to 16.8%), Sweden (19.4% to 18.5%), and the United States (30.2% to 24.4%). In the United States, early term birth rates decreased from 33.0% in 2006 to 21.1% in 2014 among births with clinician-initiated obstetric intervention, and from 29.7% in 2006 to 27.1% in 2014 among births without clinician-initiated obstetric intervention. Rates of clinician-initiated obstetric intervention increased among late preterm births in Canada (28.0% to 37.9%), Denmark (22.2% to 25.0%), and Finland (25.1% to 38.5%), and among early term births in Denmark (38.4% to 43.8%) and Finland (29.8% to 40.1%).Conclusions and Relevance: Between 2006 and 2014, late preterm and early term birth rates decreased in the United States, and an association was observed between early term birth rates and decreasing clinician-initiated obstetric interventions. Late preterm births also decreased in Norway, and early term births decreased in Norway and Sweden. Clinician-initiated obstetric interventions increased in some countries but no association was found with rates of late preterm or early term birth. [ABSTRACT FROM AUTHOR]

Aim The aim of this study was to compare vaginal misoprostol versus intravenous (i.v.) oxytocin in the management of pregnancies with second-trimester intrauterine fetal death (IUFD). Methods This randomized clinical trial was conducted on 85 pregnant women with IUFD and unripe cervix who were admitted for labor induction. Forty were randomly allocated to receive 200 mcg vaginal misoprostol every 12 h, and 45 were randomly assigned to receive high-dose i.v. oxytocin (starting from 6 mU/min to reach the maximum dose of 40 mU/min). This study is registered at (IRCT201307159568N5). Results The induction-to-delivery interval in the misoprostol group (10.5 ± 5.3 [range 4-27] h) was significantly lower than that in the oxytocin group (14 ± 6.8 [range 4-30] h) ( P = 0.009). The total hospital stay in the misoprostol group (22.6 ± 9.5 [range 12-48] h) was significantly lower than that in the oxytocin group (35.3 ± 16.4 [range 12-72] h) ( P = 0.000). Although the successful induction rate was higher in the misoprostol group, this was not significant (95% vs 86.7%, P = 0.1). Placenta retention occurred more in the oxytocin group (20% vs 5%, P = 0.03). Conclusion Both vaginal misoprostol and high-dose i.v. oxytocin are highly effective in labor induction in second-trimester pregnancies with IUFD and an unripe cervix. However, vaginal misoprostol seems to be superior to i.v. oxytocin. [ABSTRACT FROM AUTHOR]

Objective: To study the association between duration of second stage of labour and risks of maternal complications (infection, urinary retention, haematoma or ruptured sutures) in the early postpartum period.Design: Population-based cohort study.Setting and Sample: We included 72 593 mothers with singleton vaginal deliveries at ≥37 weeks of gestation in cephalic presentation, using the obstetric database from the Stockholm-Gotland region in Sweden, 2008-12.Methods: Logistic regression analysis. Odds ratios (ORs) with 95% confidence intervals (95% CI) were calculated and adjustments were made for maternal age, body mass index, height, smoking, cohabitation, gestational age, labour induction, epidural analgesia and oxytocin augmentation.Results: Rates of any complication varied by parity from 7.3% in parous women with previous caesarean section, 4.8% in primiparas and 1.7% in parous women with no previous caesarean section. Compared with a second stage <1 hour, the adjusted ORs for any complication (95% CI) in primiparas were for 1 to <2 hours 1.28 (1.11-1.47); 2 to <3 hours 1.54 (1.32-1.79), 3 to <4 hours 1.63 (1.38-1.93) and ≥4 hours 2.08 (1.74-2.49). The corresponding adjusted ORs for parous women without previous caesarean were 2.27 (1.78-2.90), 2.97 (2.09-4.22), 3.65 (2.25-5.94) and 3.16 (1.44-6.94), respectively. The adjusted ORs for women with previous caesarean were for 1 to <2 hours 1.62 (1.13-2.32); 2 to <3 hours 1.56 (1.00-2.43), 3 to <4 hours 2.42 (1.52-3.87), and ≥4 hours 2.31 (1.25-4.24).Conclusions: Risks of maternal complications in the postpartum period increase with duration of second stage of labour also after accounting for maternal, pregnancy and delivery characteristics. Special attention has to be given to parous women with previous caesarean deliveries. [ABSTRACT FROM AUTHOR]

To test the hypothesis that advanced maternal age (AMA) of 35 years and above is associated with increased risk of adverse pregnancy outcomes, we performed a population-based retrospective study using data from the 2000 National Health Survey in Oman. The last pregnancy outcomes of mothers aged ≥35 years were compared with adult mothers aged 20–34 years using bivariate and multivariate statistical techniques. Significantly increased risks of spontaneous abortion, gestational diabetes, preeclampsia, prolonged labor, and cesarean section delivery have been observed for advanced maternal age. Our findings may contribute to cross-cultural understanding of the risks associated with AMA and will facilitate evidence-based counseling of older expectant mothers. [ABSTRACT FROM PUBLISHER]

The article analyzes the global and regional trends in child marriage incidence, child marriage gap and squared child marriage gap for the past few decades. Topics discussed include legal prohibition of child marriage in various countries like India and Nigeria; the use of data about age at first marriage in the Demographic and Health Survey (DHS) to estimate the trends; and the high risk of maternal mortality for girls who give birth at an early age.

We utilized an updated nationally representative database to examine associations between maternal age and prevalence of maternal morbidity during complications of labor and delivery. We used hospital inpatient billing data from the 2009 United States Nationwide Inpatient Sample, part of the Healthcare Cost and Utilization Project. To determine whether the likelihood that maternal morbidity during complications of labor and delivery differed among age groups, separate logistic regression models were run for each complication. Age was the main independent variable of interest. In analyses that controlled for demographics and clinical confounders, we found that complications with the highest odds among women, 11-18 years of age, compared to 25-29 year old women, included preterm delivery, chorioamnionitis, endometritis, and mild preeclampsia. Pregnant women who were 15-19 years old had greater odds for severe preeclampsia, eclampsia, postpartum hemorrhage, poor fetal growth, and fetal distress. Pregnant women who were ≥35 years old had greater odds for preterm delivery, hypertension, superimposed preeclampsia, severe preeclampsia, and decreased risk for chorioamnionitis. Older women (≥40 years old) had increased odds for mild preeclampsia, fetal distress, and poor fetal growth. Our findings underscore the need for pregnant women to be aware of the risks associated with extremes of age so that they can watch for signs and symptoms of such complications.

Objective Placenta previa and prior cesarean delivery are known risk factors for placenta accreta. However, other risk factors have not been identified. Our objective was to examine risk factors for accreta using data collected prospectively in a large multicenter cohort. Study Design Secondary analysis of women with accreta compared to those without accreta in a large multicenter cesarean delivery cohort. Potential accreta risk factors were examined by univariate and multivariate analyses. Results In this study, 196 of 73,257 (0.27%) cesarean deliveries were complicated by accreta. As expected, women with increasing numbers of prior cesareans were more likely to have an accreta (p < 0.001), as were women with previa (adjusted odds ratio [OR], 34.9; 95% confidence interval [CI], 22.4-54.3). We also considered only patients with previa and examined the following variables: maternal demographics, prior cesareans, interval between deliveries, parity, body mass index, tobacco use, and coexisting hypertension or diabetes. In this model, patients with previa and two or three prior cesarean deliveries had an adjusted OR for accreta of 4.9 (95% CI, 1.7-14.3) or 7.7 (95% CI, 2.4-24.9), respectively. However, no other variables were significantly associated with accreta. Conclusion Patients with previa have increased risk for accreta that increases with the number of prior cesarean deliveries. However, no other maternal characteristics were associated with accreta. [ABSTRACT FROM AUTHOR]

Background: Despite an increase in the number of cesarean deliveries conducted worldwide, meta-analyses on the long-term effect of cesarean section (CS) on subsequent placental disorders are sparse. Objective: To examine the association between CS and three major types of placental disorders (placental abruption, placenta previa, and placenta accreta with its variants increta/percreta) in subsequent pregnancies. Search strategy: We followed the MOOSE consensus statement for meta-analyses of observational studies and searched the PubMed database for observational studies published between January 1990 and July 2011 for examining the association between CS and placental disorders in subsequent pregnancies, without focusing on the effect of increasing number of CSs. Selection criteria: We included studies which provided adjusted measures of association for multiparous singleton-pregnant women with one of the three outcomes and information about prior mode of delivery. Data collection and analysis: Five cohort and 11 case-control studies met the inclusion criteria for this meta-analysis. We combined the results of the included cohort and case-control studies as no significant heterogeneity was found across the studies. Main results: The calculated summary odds ratio was 1.47 (95% confidence interval, CI: 1.44-1.51) for placenta previa, 1.96 (95% CI: 1.41-2.74) for placenta accreta, and 1.38 (95% CI: 1.35-1.41) for placental abruption. Conclusion: In this meta-analysis, cesarean delivery appeared as a consistently reported risk factor for all three major forms of placental disorders in subsequent pregnancies.

Objectives This study aims to summarize evidence on the relation between neighborhood deprivation and the risks for preterm birth, small-for-gestational age, and stillbirth. Design The design was a systematic review and meta-analysis. Main outcome measures The main outcome measures included studies that directly compared the risk of living in the most deprived neighborhood quintile with least deprived quintile for at least one perinatal outcome of interest (preterm delivery, small-for-gestational age and stillbirth). Methods Study selection was based on a search of Medline, Embase and Web of Science for articles published up to April 2012, reference list screening, and email contact with authors. Data on study characteristics, outcome measures, and quality were extracted by two independent investigators. Random-effects meta-analysis was performed to estimate unadjusted and adjusted summary odds ratios with the associated 95% confidence intervals. Results We identified 2863 articles, of which 24 were included in a systematic review. A meta-analysis ( n = 7 studies, including 2 579 032 pregnancies) assessed the risk of adverse perinatal outcomes by comparing the most deprived neighborhood quintile with the least deprived quintile. Compared with the least deprived quintile, odds ratios for adverse perinatal outcomes in the most deprived neighborhood quintile were significantly increased for preterm delivery (odds ratio 1.23, 95% confidence interval 1.18-1.28), small-for-gestational age (odds ratio 1.31, 95% confidence interval 1.28-1.34), and stillbirth (odds ratio 1.33, 95% confidence interval 1.21-1.45). Conclusions Living in a deprived neighborhood is associated with preterm birth, small-for-gestational age and stillbirth. [ABSTRACT FROM AUTHOR]

The authors discuss aspects of vasa previa, a medical condition in which fetal vessels traverse the membrane located between cervix and part of the fetus, and routine prenatal ultrasound. Topics discussed include diagnosis of vasa previa, prenatal care, and fetal fibronectin (fFN) testing. They mention that colour flow Doppler sonography should be conducted as an adjunct to rule out vasa previa in patients.

Background: The association between inflammatory bowel disease (IBD) and preterm delivery is controversial. Study size, quality, and design have been inconsistent, making it difficult to assess the relationship between IBD and preterm delivery. Objective: Utilizing a systematic search of Pubmed for all relevant literature, this review seeks to clarify the correlation between IBD and preterm delivery and to assess the impact of disease activity and medication usage on this outcome. Results: The available evidence is inadequate to make any robust claims about the association between IBD and preterm delivery. IBD in pregnant women may represent a risk for preterm delivery, and it is probable that IBD activity augments this risk. Many of the medications used to treat IBD also have a correlation with preterm delivery. Conclusions: While an association between IBD and preterm delivery may exist, further well-designed prospective studies are necessary to determine how the course and management of disease may impact this outcome.

Objective: We sought to investigate the incidence, maternal risk factors, and perinatal outcomes of women with complete and partial placental retention in a tertiary care teaching hospital in Southwestern Germany. Study design: We performed an unmatched case-control study with cases occurring between July 2000 and June 2007. Women were included into the study if they completed at least the 24th week of gestation and were diagnosed with placental retention requiring surgical intervention. We selected two controls per case and performed univariate and multivariate logistic regression analyses to identify risk factors for complete and partial placental retention. Results: A total of 161 cases (2.02%) were identified out of 7978 deliveries. The 1-year prevalence of all types of placental retention continuously increased during the 6-year study period from 0.93% to 3.26%. A significant independent risk factor for all types of placental retention in the multivariate logistic regression model was a previous retention of the placenta [odds ratio (OR)=21.723, 95% confidence interval (CI) 6.07-77.7]. Independent protective factors against all types of placental retention were a non-anterior and non-posterior placenta location (OR=0.561, 95% CI 0.35-0.91), and a cesarean delivery with (OR=0.193, 95% CI 0.09-0.40) and without labor (OR=0.482, 95% CI 0.27-0.86). Women without partial placental retention delivered neonates with better 5-min APGAR scores (OR=0.78, 95% CI 0.65-0.95). Conclusion: A thorough medical history and a vigilant prepartum ultrasound help in identifying women at risk for placental retention. [ABSTRACT FROM AUTHOR]

Objective: Placenta accreta is an increasingly prevalent and potentially dangerous complication of pregnancy. Although most studies on the subject have addressed the risk factors for the development of this condition, evidence on maternal and neonatal outcomes for these pregnancies is scarce. The objective of the present study is to compile current evidence with regard to risk factors as well as adverse outcomes associated with placenta accreta. Methods: We conducted a complete literature review using PubMed, MEDLINE, Cochrane Database Reviews, UptoDate, DocGuide, as well as Google scholar and textbook literature for all articles on placenta accreta, and any one of the following keywords: 'risk factors', 'maternal outcomes', 'neonatal outcomes', 'morbidity', and 'mortality'. Individual case reports were excluded. Results: We reviewed 34 studies conducted between 1977 and 2012. A total number of 508,617 deliveries were studied, with 865 cases of confirmed placenta accreta (average pooled incidence=1/588). The development of placenta accreta appears to be most strongly predicted by a history of cesarean section, low-lying placenta/previa, in vitro fertilization pregnancy, as well as elevated second-trimester levels of α-fetoprotein and β-human chorionic gonadotropin. The most significant maternal outcomes include the need for postpartum transfusion due to hemorrhage and peripartum hysterectomy. Maternal mortality remains rare but significantly higher than among matched, postpartum controls. Important neonatal outcomes include preterm birth, low birth weight, small for gestational age, and reduced 5-min Apgar scores. Whether the need for neonatal intensive care unit admission and steroid administration is iatrogenic and whether an increased risk of perinatal mortality is a clinically significant and independent outcome remain controversial. Conclusion: Although there is a significant shortage of studies on the subject, it appears that placenta accreta is associated with adverse maternal and neonatal outcomes, some of which may be life threatening. Prenatal diagnosis and adequate planning, particularly in high-risk populations, may be indicated for the reduction of these adverse outcomes. [ABSTRACT FROM AUTHOR]

Aims Investigate risk factors for obstetric anal sphincter injury ( OASI) and their incidence between 2006 and 2010 at a regional teaching hospital in Australia. Determine whether a correlation exists between a decrease in OASI rates and an increase in mediolateral episiotomies. Materials and Methods A retrospective observational study conducted at the Geelong Hospital, Barwon Health, Victoria, Australia. Every adequately documented vaginal birth from 2006 to 2010 in the hospital was included ( N = 7314, cases of OASI = 239). Patient data were obtained from the Barwon Health Birth Outcomes System database. Multinomial logistic regression, Pearson's correlation coefficient and relative risk calculations were used for analysis. Results Risk factors for OASI include nulliparity ( OR 2.64, 95% CI 1.95-3.57, P < 0.01), instrumental delivery ( OR 2.54, 95% CI 1.82-3.55, P < 0.01) and birth weight greater than 4 kg ( OR 1.56, 95% CI 1.11-2.19, P = 0.01). There was a significant correlation between increasing mediolateral episiotomy use from 12.56% to 20.10% and a reduction in OASI rates over the 5-year period ( Pearson's correlation coefficient: −0.94, P = 0.02). The correlation remained when analysing normal vaginal births in isolation from instrumental ( Pearson's correlation coefficient: −0.89, P = 0.04). Conclusions Clear risk factors for OASI include nulliparity, macrosomia and instrumental delivery. There was a significant correlation between increasing mediolateral episiotomy rates from 12.56% to 20.10% and decreasing OASI. [ABSTRACT FROM AUTHOR]

Epidural analgesia is a widely available method of pain relief in labour in Western countries. This article analyses the various adverse outcomes of labour and birth after the administration of epidural analgesia. A literature review found that the use of intrapartum epidural analgesia for women with low-risk pregnancy has not only disempowered women but can also lead to maternal and fetal morbidity connected with major obstetric interventions, such as operative deliveries. Epidural analgesia also interferes with breastfeeding success and effective oxytocin circulation in the maternal blood-stream, and may even impact on childhood behavioural development.

We sought to predict neonatal metabolic acidosis at birth using antepartum obstetric characteristics (model 1) and additional characteristics available during labor (model 2). In 5667 laboring women from a multicenter randomized trial that had a high-risk singleton pregnancy in cephalic presentation beyond 36 weeks of gestation, we predicted neonatal metabolic acidosis. Based on literature and clinical reasoning, we selected both antepartum characteristics and characteristics that became available during labor. After univariable analyses, the predictors of the multivariable models were identified by backward stepwise selection in a logistic regression analysis. Model performance was assessed by discrimination and calibration. To correct for potential overfitting, we (internally) validated the models with bootstrapping techniques. Of 5667 neonates born alive, 107 (1.9%) had metabolic acidosis. Antepartum predictors of metabolic acidosis were gestational age, nulliparity, previous cesarean delivery, and maternal diabetes. Additional intrapartum predictors were spontaneous onset of labor and meconium-stained amniotic fluid. Calibration and discrimination were acceptable for both models (c-statistic 0.64 and 0.66, respectively). In women with a high-risk singleton term pregnancy in cephalic presentation, we identified antepartum and intrapartum factors that predict neonatal metabolic acidosis at birth.

A broad set of academic literatures shows that childbearing is associated with a variety of negative health outcomes for teenage mothers. Many researchers question whether teenage childbearing is the causal explanation for the negative outcomes (i.e., whether there is a biological effect of teenage childbearing or whether the relationship is due to other factors correlated with health and teenage childbearing). This study investigates the relationship between teenage childbearing and labor and delivery complications using a panel of confidential birth certificate data over the period from 1994 to 2003 from the state of Texas. Findings show that compared to mothers aged 25 to 29 having their first child, teenager mothers appear to have superior health in most—but not all—labor and delivery outcomes. [ABSTRACT FROM AUTHOR]

The purpose of this study was to examine the association between prenatal alcohol consumption and the occurrence of placental abruption and placenta previa in a population-based sample. We used linked birth data files to conduct a retrospective cohort study of singleton deliveries in the state of Missouri during the period 1989 through 2005 ( n = 1,221,310). The main outcomes of interest were placenta previa, placental abruption and a composite outcome defined as the occurrence of either or both lesions. Multivariate logistic regression was used to generate adjusted odd ratios, with non-drinking mothers as the referent category. Women who consumed alcohol during pregnancy had a 33% greater likelihood for placental abruption during pregnancy (adjusted odds ratio (OR), 95% confidence interval (CI) = 1.33 [1.16-1.54]). No association was observed between prenatal alcohol use and the risk of placenta previa. Alcohol consumption in pregnancy was positively related to the occurrence of either or both placental conditions (adjusted OR [95% CI] = 1.29 [1.14-1.45]). Mothers who consumed alcohol during pregnancy were at elevated risk of experiencing placental abruption, but not placenta previa. Our findings underscore the need for screening and behavioral counseling interventions to combat alcohol use by pregnant women and women of childbearing age. [ABSTRACT FROM AUTHOR]

A case-cohort study was performed to clarify and compare the risk factors for placental abruption and placenta previa. This study reviewed 242 715 births at 125 centers of the perinatal network in Japan from 2001 through to 2005 as a base-cohort. Women with singleton pregnancies delivered after 22 weeks of gestation were included. The evaluation determined the risk factors for placental abruption and placenta previa. Five thousand and thirty-six births (2.1%) were determined as the subcohort by random selection. Acute-inflammation-associated clinical conditions (premature rupture of membranes and clinical chorioamnionitis) and chronic processes associated with vascular dysfunction or chronic inflammation (chronic and pregnancy-induced hypertension, pre-existing or gestational diabetes and maternal smoking) was examined between the two groups. Placental abruption and placenta previa were recorded in 10.1 per 1000 and 13.9 per 1000 singleton births. Risk factors for abruption and previa, respectively, included maternal age over 35 years (adjusted risk ratios [RRs] = 1.20 and 1.78), IVF-ET (RRs = 1.38 and 2.94), preterm labor (RRs = 1.63 and 3.09). Smoking (RRs = 1.37), hypertension (RRs = 2.48), and pregnancy-induced hypertension (RR = 4.45) were risk factors for abruption but not for previa. On the other hand, multiparity (RR = 1.18) was a risk factor for previa but not for abruption. The rates of acute-inflammation-associated conditions and chronic processes were higher among women with abruption than with previa. (RR 2.0 and 4.08, respectively). The case-cohort study technique elucidated the difference in the risk factors for placental abruption and placenta previa. [ABSTRACT FROM AUTHOR]

Aims: To examine the effect of a prior cesarean delivery on neonatal outcomes. Methods: We conducted a retrospective cohort study on all women with a prior livebirth who delivered at the Royal Victoria Hospital between 2001 and 2006. We defined our exposure as a positive history for cesarean delivery and used unconditional logistic regression analysis to estimate the adjusted effect of a previous cesarean delivery on adverse neonatal outcomes. Results: A total of 18,673 births took place of which 9708 were in women with a prior livebirth (77.0% with no previous cesarean delivery and 23.0% with a previous cesarean delivery). As compared to newborns delivered by mothers with no prior cesarean delivery, increasing number of prior cesarean deliveries was associated with an increasing risk of preterm birth [odds ratio (OR) 1.23, 95% confidence interval (CI) 1.09-1.39]; respiratory distress syndrome (OR 3.54, 95% CI 2.02-5.91); and admission to the neonatal intensive care unit (OR 1.41, 95% CI 1.25-1.60). These findings were predominantly due to differences in gestational age and mode of delivery. Conclusion: Having a prior cesarean delivery is associated with an increased risk of adverse neonatal outcomes. Adverse neonatal outcomes in subsequent pregnancies is additional evidence to suggest that unless specifically indicated, cesarean delivery should be avoided. [ABSTRACT FROM AUTHOR]

Objective: To find out the causative factors for rising rate of ectopic pregnancy in young women at periphery. Design: Descriptive study. Place and Duration of Study: Maula Bakhsh Teaching Hospital ( Obstetrical and gynaecological unit) Sargodha , from January 2008 - December 2008. Patients and Methods: All patients who were presented in labour room emergency and gynaecological out patients department with confirmed diagnosis of ectopic pregnancy on USG were included in the study. A pre-formed proforma was used to record the details about the demographic features, pre-existing risk factors for ectopic pregnancy, clinical features at presentation and management. Results: Frequency of ectopic pregnancy was too high in our study compared to international studies. Majority of patients were young and nullipara. Leading risk factor is pelvic inflammatory disease due to septic induced abortion. 92% of patients had acute presentation. Conclusions: Rising rate of ectopic pregnancy was found in young, nulliparous women secondary to pelvic inflammatory disease. The frequency can be reduced by awareness of reproductive health care, liberal contraceptive utilization, acceptable adequate planned family. Early diagnosis and timely referral may be helpful in treating the patients prior to tubal rupture with decreased morbidity and mortality. [ABSTRACT FROM AUTHOR]

Objective: To study the causative factors responsible for avoidance of Breast Feeding in post-partum women attending the post-natal OPD in MH Rawalpindi. Design: Comparative cross sectional study. Setting: Dept of Gynae and Obstetrics, Military Hospital, Rawalpindi. Tertiary care centre from all the Pakistan dealing with other ranks of Pak Army. Duration: Nine months (From 01.01.2007 to 1.10.2007). Materials and Methods: Study was done on 1000 patients at post-natal Gynae OPD. Patients were divided into two groups of 500 each. Those patients who were exclusively breast feeding their babies were included in group-II while group-I included those patients who were not breast feeding their babies at all. Patients demographic data was entered on questionnaire and factors involved were interpreted. The most important causative factor responsible for avoidance of breast feeding in group-I were noted down. The mothers in group-II were enquired about that problem. Data was analyzed by using computer software programme SPSS version 11. Chi square test was used to see the significance of difference between group-I and group-II and results were considered significant if P value is less than 0.05. Results: The study showed that as compared to group-II causative factors involved in avoidance of breast feeding in group-I were pain at operated site 148, working women 38, Sick baby 26,Cracked nipples and mastitis 59, Breast abscess 4, Social Myths 58, Multiple Births 2, Inverted Nipples 5 and failure of proper counseling 160. Conclusions: Most of the factors responsible for avoidance of breast feeding are preventable and treatable. General population should be educated regarding the benefits of breast feeding in the mother and baby. Thus reducing mortality rate in woman and infants. [ABSTRACT FROM AUTHOR]
