Fetal rotation examined with ultrasound in a sub-Saharan population: A longitudinal cohort study.

Occiput posterior (OP) position rates at birth are 5%-8% in studies mainly comprising white European women. The anthropoid pelvis is common in black African women. This pelvic shape has a narrow anterior segment and an ample room posteriorly. The fetal head is wider posteriorly, and the OP position may be favorable in women with an anthropoid pelvic shape. We aimed to examine the fetal rotation with ultrasound longitudinally during the active phase of labor in a sub-Saharan population. We also aimed to examine associations between fetal position, delivery mode, and duration of labor. The study was conducted at Kilimanjaro Christian Medical Centre in Moshi, Tanzania from the 19th of November 2023 to 13th of April 2024. Women with a single fetus in cephalic presentation, gestational age >37 weeks, without previous or pre-labor cesarean section were eligible. Fetal position was classified as occiput anterior (OA) from 10 to 2 o'clock, occiput transverse (OT) at 3 or 9 o'clock, and OP position from 4 to 8 o'clock. The study participants comprised 215 women. Fetal positions at admission, in the first and second stage of labor and at birth are presented in the graphical figure. In all, 65/215 (30.2%) fetuses were in OP position at admission, 59/204 (28.9%) in the first stage, 38/210 (18.1%) in the second stage and 35/215 (16.3%) were delivered in OP position. The OP rates at birth were 25/92 (27.2%) in nulliparous and 10/123 (8.1%) in parous women. The operative delivery rate was 10/157 (6.4%) in women with ultrasound assessed fetal position as OA in the second stage (six cesarean section and four vacuum extractions), and 28/48 (58.3%) in the non-OA group (27 cesarean section and one vacuum extraction) (p < 0.01). The hazard ratio for delivery in the second stage was 0.26 (95% CI 0.13-0.52) for the non-OA versus the OA group in nulliparous women and 0.25 (95% CI 0.12-0.52) in parous women. The persistent OP position rate at birth was higher than previously reported, and the operative intervention rate was nine time higher in women with the fetus in non-OA versus OA position in the second stage.

Decreased expression of Syndecan- 1 (CD138) in the endometrium of adenomyosis patients suggests a potential pathogenetic role.

Adenomyosis is a special subtype of endometriosis, affecting the myometrium, affecting about 20% of women in the reproductive age period. Clinical symptoms and intensity are diverse and can vary from heavy menstrual bleeding and dysmenorrhea to infertility and repeated pregnancy losses. Thus, patients often present with a long history of illness pending presumptive clinical or surgical diagnosis. A definitive diagnosis of adenomyosis is made upon histopathological examination verifying ectopic endometrial tissue (endometrial glands and/or stroma) within the myometrium, surrounded by hyperplastic and hypertrophic smooth muscles. However, nowadays ultrasonographic and/or MRI signs can precisely detect it as well. The precise etiology and pathogenesis remain unclear. One theory assumes that adenomyosis occurs through metaplastic transformation or migration of stem cell-like cells. Our study examined the immunohistochemical expression of the transmembrane proteoglycan Syndecan-1 (CD 138), a multifunctional matrix receptor and signaling co-receptor, in the endometrium of 35 patients (n = 21 with adenomyosis and n = 14 as a control group) in the period 2016-2017. As a pilot study, we concluded that Syndecan-1 is downregulated in adenomyosis patients compared to the control group, supporting its potential role in the development of adenomyosis. Our study did not find a correlation between the immune-expression of Syndecan-1 and the menstrual cycle phase. For clinical significance in relation to our results, the investigated data showed that the downregulation of Syndecan-1 in adenomyotic patients in our study may suggest a role in promoting the invasiveness of endometriotic islands within the myometrium. However, further studies are still needed to understand the mechanistic contribution of Syndecan-1 to the pathogenesis of adenomyosis.

The complexity and challenges of fertility preservation in women with cervix cancer-A prospective cohort study reporting on reproductive outcome and overall survival.

Our objective was to assess the feasibility of fertility preservation (FP) in women referred for cervix cancer, the long-term reproductive outcome, and overall survival. Prospective cohort study of patients referred for FP counseling between 1999 and 2021 to the FP program of Karolinska University Hospital, Stockholm, Sweden. Baseline data included age, parity, disease stage, treatment characteristics, and FP methods applied. Data on reproductive outcomes and overall survival (by October 19, 2023) were retrieved from clinical registries and a population-based register. ClinicalTrials.gov NTC04602962. In total, 91 women were referred, 67% with stage I cancers and 25%, 7%, and 1% with stages II, III, and IV, respectively. Cancers were diagnosed during pregnancy or postpartum in six cases. Cancer treatments included fertility-sparing surgery in 14%, hysterectomy in 30%, and radiochemotherapy in 79% of cases. The treatment modality did not rule out the possibility to undergo FP, and following counseling, 68 patients elected to undergo FP by cryopreservation of embryos or oocytes (N = 11), ovarian tissue (N = 54), or both (N = 3). After a mean follow-up of 8.1 years, 25 women (37%) returned to the center, five women achieved conception either spontaneously or through assisted reproduction, and 11 women became mothers through adoption or surrogacy. In the group of women receiving radical surgery or chemo/radiotherapy, no live births using cryopreserved specimens have yet been achieved. During follow-up, 7 women (10%) in the FP group and 5 women (24%) in the group without FP had died of their disease. Cancer recurrence was documented in 19 patients. Our findings underscore the complexity and challenges associated with FP in the context of cervix cancer. Results of this study demonstrate that many women diagnosed with cervix cancer at reproductive age desire to achieve parenthood. While fertility-sparing surgery can allow pregnancy, those who undergo a hysterectomy are limited to adoption, surrogacy, or the emerging possibility of uterus transplantation.

Hospital obstetric volume and maternal outcomes: Does hospital size matter?

AbstractIntroductionIn recent decades, centralization of health care has resulted in a number of obstetric unit closures. While studies support better infant outcomes in larger facilities, few have investigated maternal outcomes. We investigated obstetric unit closures over time and whether obstetric volume is associated with onset of labor, postpartum hemorrhage (PPH) and obstetric anal sphincter injury (OASIS).Material and MethodsAll births registered in Sweden between 1992 and 2019 (Medical Birth Register, N = 2 931 140), linked with data on sociodemographic characteristics and maternal/infant diagnoses, were used to describe obstetric unit closures. After excluding congenital malformations, obstetric volume was categorized (low: 0–1999, medium: 2000–3999, high: ≥4000 births per year). Restricting to 2004 onwards (after most closures), the association between volume and onset of labor (spontaneous as reference) was estimated. Restricting to spontaneous, full‐term (≥37 weeks gestation) cephalic births, we then investigated the association between volume and PPH and, after excluding planned cesarean sections, OASIS. Odds ratios from multilevel (logistic) models clustered by hospital were estimated.ResultsThe 20 dissolved obstetric units (1992–2019) had relatively stable volume until their closure. Compared to the average, women birthing in the highest volume hospitals were older (31.3 years vs. 30.4) and a higher proportion had &gt;12 years of education (57 vs. 51%). Compared to high‐volume hospitals, there was no significant difference in labor starting by elective cesarean section or induction, rather than spontaneously, among low (OR 0.88, 95% CI: 0.73–1.06) and medium (OR 0.84, 95% CI 0.71–1.01) volume hospitals. There were lower odds of PPH among low (OR 0.72, 95% CI 0.63–0.85) and medium (OR 0.83, 95% CI 0.72–0.97) volume hospitals. No significant association was found between obstetric volume and OASIS (low: OR 0.98, 95% CI 0.82–1.18; medium: OR 0.90, 95% CI 0.77–1.05).ConclusionsThere was not a strong relationship between obstetric volume and maternal outcomes. Reduced odds of PPH for women birthing in smaller units may be due to triaging high‐risk pregnancies to larger hospitals. While there was no significant association between obstetric volume and onset of labor or OASIS, other important factors related to closures, such as workload and overcrowding, should be investigated.

Prediction of uterine rupture in singleton pregnancies with one prior cesarean birth undergoing <scp>TOLAC</scp>: A cross‐sectional study

AbstractIntroductionBeing able to counsel patients with one prior cesarean birth on the risk of uterine rupture with a trial of labor after cesarean, (TOLAC) is an important aspect of prenatal care. Despite uterine rupture being a catastrophic event, there is currently no successful, validated prediction model to predict its occurrence.Material and MethodsThis was a cross‐sectional study using US national birth data between 2014 and 2021. The primary objective was to identify risk factors for uterine rupture during TOLAC and to generate a prediction model for uterine rupture among singleton gestations with one prior cesarean as their only prior birth. The secondary objective was to describe the maternal and neonatal morbidity associated with uterine rupture. The association of all candidate variables with uterine rupture was tested with uni‐ and multi‐variable logistic regression analyses. We included term and preterm singleton pregnancies with one prior birth that was cesarean birth (CB) with cephalic presentation undergoing TOLAC. We excluded pregnancies with major structural anomalies and chromosomal abnormalities. The Receiver Operating Characteristics (ROC) Curve was generated. p value &lt;0.001 was considered statistically significant.ResultsOf the 270 329 singleton pregnancies with one prior CB undergoing TOLAC during the study period, there were 957 cases of uterine rupture (3.54 cases per 1000). Factors associated with uterine rupture in multivariable models were an interpregnancy interval &lt; 18 months versus the reference interval of 24–35 months (aOR 1.55; 95% CI, 1.19–2.02), induction of labor (aOR 2.31; 95% CI, 2.01–2.65), and augmentation of labor (aOR 1.94; 95% CI, 1.70–2.21). Factors associated with reduced rates of uterine rupture were maternal age &lt; 20 years (aOR 0.33, 95% CI 0.15–0.74) and 20–24 years (aOR 0.79, 95% CI 0.64–0.97) versus the reference of 25–29 years and gestational age at delivery 32–36 weeks versus the reference of 37–41 weeks (aOR 0.55, 95% CI 0.38–0.79). Incorporating these factors into a predictive model for uterine rupture yielded an area under the receiver‐operating curve of 0.66. Additionally, all analyzed maternal and neonatal morbidities were increased in the setting of uterine rupture compared to non‐rupture.ConclusionsUterine rupture prediction models utilizing TOLAC characteristics have modest performance.

Maternal asthma during pregnancy and the likelihood of neurodevelopmental disorders in offspring.

Asthma is the most common chronic disease during pregnancy. Maternal asthma has been associated with a multitude of unwanted pregnancy outcomes, in some studies also with neurodevelopmental disorders. Here we investigated associations between maternal asthma and neurodevelopmental disorders. We studied a retrospective population-based cohort of 1 271 439 mother-child pairs from singleton live births in Finland between the years 1996-2018. We used multiple high-cover registers for data collection. Adjusted unconditional Cox regression models were used to investigate associations between maternal asthma, asthma medication used during pregnancy, and offspring's neurodevelopmental disorder diagnoses. We identified 106 163 mother-child pairs affected by maternal asthma. We found that maternal asthma was associated with offspring neurodevelopmental disorders, but the differences in absolute prevalence between the control and exposure groups were small. Attention-deficit hyperactivity disorder (ADHD) was found in 4114 (3.9%) offspring with maternal asthma and in 32 122 (3.0%) controls (adjusted hazard ratio (HR): 1.49; 95% CI 1.44-1.54); autism in 1617 (1.5%) offspring versus 13 701 (1.3%) controls (HR: 1.33; 95% CI 1.26-1.40); motor-developmental disorder in 1569 (1.5%) offspring versus 12 147 (1.1%) controls (HR: 1.37; 95% CI 1.30-1.45); language disorder in 3057 (2.9%) offspring versus 28 421 (2.7%) controls (HR: 1.13; 95% CI 1.08-1.17), learning disabilities in 849 (0.8%) offspring versus 6534 (0.6%) controls (HR: 1.51; 95% CI 1.41-1.62); mixed developmental disorder in 1633 (1.5%) offspring versus 14 434 (1.3%) controls (HR 1.20; 95% CI, 1.14-1.26); and intellectual disability in 908 (0.9%) versus 9155 (0.9%) controls (HR: 1.12; 95% CI 1.04-1.20). No substantial differences were found between allergic and non-allergic asthma phenotypes, and neither allergic tendency nor respiratory infection was associated with a similar likelihood of neurodevelopmental disorders. Maternal asthma and allergic and non-allergic phenotypes showed weak associations with the offspring's neurodevelopmental disorders. The association is concerned especially with learning disabilities, ADHD, motor development, and autism.

May the indication for a previous cesarean section affect the outcome at trial of labor in women with induction of labor? Aretrospective cohort study.

Cesarean sections are increasing worldwide and are associated with altered risks of complications for both mother and child. Vaginal birth after cesarean section is associated with lower maternal and neonatal morbidity than in repeat cesarean section. Only a few studies have considered the indication for the previous cesarean section to be of importance for the outcome of subsequent labor. The aim of this study was to evaluate whether the indication for a previous cesarean section affects the outcomes at a subsequent delivery in women with induction of labor. This retrospective cohort study of the four largest delivery units in Stockholm during 2012-2015 included 1150 women with one previous cesarean section with induction of labor. women with induced labor and a previous cesarean section, singleton pregnancy, cephalic presentation, gestational age of ≥34 weeks. The women were grouped by indication for the previous cesarean section. mode of delivery (vaginal birth after previous cesarean section or repeat cesarean section). induction to delivery time, postpartum hemorrhage, uterine rupture. Neonatal outcomes: birth weight, Apgar score <7, arterial umbilical cord blood gas pH <7.0. Our study found that the indication of labor dystocia at the previous cesarean section, increased the risk of repeat cesarean section (aOR 5.35; 95% CI: 1.64-17.50) in women with induction of labor. Other risk factors for repeat cesarean section were birth weight >4000 g, maternal BMI ≥30 or if vaginal prostaglandin was used as the method for induction of labor. A previous vaginal delivery and use of oxytocin increased the chance of a vaginal delivery in this group of women. Our study showed that the indication for the previous cesarean section affects the outcome in the subsequent delivery in women with induction of labor. If the indication for the previous cesarean section was labor dystocia, the risk of repeat cesarean section was increased.

The interplay of body mass index, gestational weight gain, and birthweight over 3800 g in vaginal breech birth: A retrospective study.

Optimal counseling of women for vaginal breech birth requires consideration of both established and emerging risk factors for adverse perinatal outcomes. Currently, rising prevalences of maternal obesity and impaired glucose tolerance challenge obstetric care. We aimed to investigate the effects of these parameters on the outcome of vaginal breech birth to improve counseling practices. A total of 361 women (without previous vaginal births) attending vaginal birth of a singleton fetus in breech presesntation between 01/2015 and 11/2021 were included in this retrospective single-center study. Data were derived from the hospital data base. We analyzed the effect of the maternal body mass index (BMI) at birth (compared to pre-pregnancy BMI), excessive weight gain, gestational diabetes, and neonatal birthweight on obstetrical and neonatal short-term outcomes (intrapartum cesarean delivery, performance of obstetric maneuvers (Løvset-, Bracht-, Veit-Smellie maneuver and Bickenbach's arm delivery), admission to the neonatal unit, Apgar score after 5 minutes<7, and arterial cord pH-value <7.10). Multivariable logistic regression was used for analysis and adjustment of variables. Overall, 246 women (68.1%) had a successful vaginal birth. Intrapartum cesarean delivery (n = 115/361; 31.9%) was independently associated with maternal BMI at birth (p = 0.0283, aOR = 1.87 (1.19-3.97)) if birthweight was ≥3800 g. The rate of intrapartum cesarean delivery was also higher in women with gestational diabetes (p = 0.0030, aOR = 10.83 (2.41-60.84)). A significantly higher risk of neonatal acidosis (arterial pH-value <7.10) was observed in women with BMI at birth ≥30 kg/m2 (p = 0.0345, aOR = 1.84 (1.04-3.22)) without affecting other outcomes. Pre-pregnancy BMI, gestational weight gain and BMI-gain did not significantly affect the obstetrical and neonatal birth outcomes. When neonatal birthweight is ≥3800 g, maternal BMI at birth (p = 0.0283; aOR = 1.87 (1.19-3.97)) is independently associated with the rate of intrapartum cesarean delivery. However, pre-pregnancy BMI and BMI-gain during pregnancy were not associated with the need for intrapartum cesarean delivery or other adverse outcomes. Consequently, BMI at the time of birth could be more informative than pre-pregnancy BMI and may improve counseling of women attempting vaginal breech birth.

Prevalence and associated factors of intimate partner violence against pregnant women who attend antenatal care in Denmark and Spain: A digital screening approach.

Intimate partner violence against women is a global health issue. Exposure to intimate partner violence during pregnancy leads to health-related problems for both the mother and the newborn. However, current knowledge on its occurrence varies widely and assessing the problem using standardized tools in different contexts is needed. This study aimed to estimate the prevalence and associated factors of IPV in pregnant women in Denmark and Spain through digital screening tools. A cross-sectional design was used to systematically screen for intimate partner violence among pregnant women attending antenatal care by using standardized digital screening tools, Woman Abuse Screening Tool and Abuse Assessment Screen. A total of 17 220 pregnant women in Denmark and 2222 pregnant women in Spain were invited to participate. The response rate was high in both countries (77.3% and 92.5%, respectively). Overall, 6.9% (n = 913) and 13.7% (n = 282) screened positive in Denmark and Spain, respectively. Logistic regressions estimated crude and adjusted odds ratio with 95% confidence intervals of the relationship between sociodemographic variables and intimate partner violence. In both countries, being unmarried and lacking social support were risk factors of intimate partner violence. Additionally, in Denmark, pregnant women older than 40 years, unemployed or foreign, were at higher risk, while having higher educational levels was a protective factor. In Spain, not having a partner at the time of questionnaire completion and having at least one child prior to the current pregnancy were risk factors of intimate partner violence. Prevalence results and found associated factors contribute to a more comprehensive understanding of the occurrence of intimate partner violence during pregnancy in Denmark and Spain, while highlighting the feasibility of digital systematic screening in antenatal settings.

Perinatal death in the Nordic countries in relation to gestational age: The impact of registration practice.

Although perinatal death rates in the Nordic countries are among the lowest in the world, the risk of perinatal death is unevenly distributed across the Nordic countries, despite similarity in health care systems and pregnancy care. Birth registration practices across countries may explain some of the differences. We investigated differences in national registration of perinatal mortality within the Nordic countries and its impact on perinatal mortality according to gestational age. Each country provided information by answering a questionnaire about registration of perinatal deaths. Furthermore, we collected aggregated count data based on Medical Birth Registries (MBR) from all Nordic countries in 2000 to 2021. Perinatal mortality was defined as stillbirth or neonatal death occurring within first 7 days of life. Data were grouped into six groups by gestational age (GA): extremely preterm (>28 + 0 weeks, subdivided into 22 + 0-23 + 6 and 24 + 0-27 + 6), very preterm (GA 28 + 0-31 + 6), moderate preterm (GA 32 + 0-33 + 6), late preterm (GA 34 + 0-36 + 6), term (GA 37 + 0-40 + 6) and late term or post-term birth (GA ≥ 41 + 0). Perinatal mortality rate and risk ratio with 95% confidence intervals were calculated per country for each gestational age group. For Denmark, separate analyses included and excluded induced abortions. The study included 6 343 805 live births, 22 727 stillbirths and 8932 liveborn infants who died within the first week of life after GA 22 + 0. Further 25 057 births were included with GA < 22 + 0, unknown GA and as a result of induced abortion. Overall, perinatal mortality rates decreased during year 2000-2021 in all Nordic countries. After exclusion of induced abortions, the perinatal mortality rate was similar in the five Nordic countries. The perinatal mortality rate for extremely preterm born infants was highest in Denmark, whereas the highest rate among infants born late term/post-term was in Sweden. The perinatal mortality rate in the Nordic countries is still decreasing, especially in the group of extremely preterm born infants. This study supports the need for further standardization of birth registration practices to ensure the validity of international comparisons.
