Ongoing effects of preterm birth on the dopaminergic and noradrenergic pathways in the frontal cortex and hippocampus of guinea pigs.

Children born preterm have an increased likelihood of developing neurobehavioral disorders such as attention-deficit hyperactivity disorder (ADHD) and anxiety. These disorders have a sex bias, with males having a higher incidence of ADHD, whereas anxiety disorder tends to be more prevalent in females. Both disorders are underpinned by imbalances to key neurotransmitter systems, with dopamine and noradrenaline in particular having major roles in attention regulation and stress modulation. Preterm birth disturbances to neurodevelopment may affect this neurotransmission in a sexually dimorphic manner. Time-mated guinea pig dams were allocated to deliver by preterm induction of labor (gestational age 62 [GA62]) or spontaneously at term (GA69). The resultant offspring were randomized to endpoints as neonates (24h after term-equivalence age) or juveniles (corrected postnatal day 40, childhood equivalence). Relative mRNA expressions of key dopamine and noradrenaline pathway genes were examined in the frontal cortex and hippocampus and quantified with real-time PCR. Myelin basic protein and neuronal nuclei immunostaining were performed to characterize the impact of preterm birth. Within the frontal cortex, there were persisting reductions in the expression of dopaminergic pathway components that occurred in preterm males only. Conversely, preterm-born females had increased expression of key noradrenergic receptors and a reduction of the noradrenergic transporter within the hippocampus. This study demonstrated that preterm birth results in major changes in dopaminergic and noradrenergic receptor, transporter, and synthesis enzyme gene expression in a sex- and region-based manner that may contribute to the sex differences in susceptibility to neurobehavioral disorders. These findings highlight the need for the development of sex-based treatments for improving these conditions.

Long working hours and obstetric complications: A cross-sectional study among female doctors

ObjectiveTo investigate the effects of long working hours on pregnancy complications and obstetric outcomes among female doctors working in tertiary care hospitals of Karachi. Study designA cross-sectional study was conducted on 149 female MBBS graduates (mean age: 33.5 ± 7.3 years) who had conceived at least once, currently working in two tertiary-care hospitals of Karachi. Data was collected through a self-administered questionnaire containing questions regarding demography and course of 1st pregnancy of the participants including working hours, antenatal and natal complications. Means and standard deviations were calculated for continuous variables with frequencies and percentages for categorical variables. The association between long working hours and different antenatal and natal complications was investigated using Chi-square test and T-test. ResultsOut of 149 participants included in final analysis, 85.9 % doctors gave birth to alive babies while 12.8 % had miscarriages and 1.3 % had stillbirth. Mean working hours during the three trimesters were found to be 53.76, 53.66 and 48.7, respectively. 43 % doctors experienced at least one antenatal complication during their pregnancy. Women who worked more than or equal to 55 h per week during 1st, 2nd and 3rd trimester of their pregnancy experienced more antenatal complications than women who worked less than 55 h (p-value=0.042, 0.021 and 0.018 respectively). 61.7 % females experienced at least one natal complication, most common of which was induction of Labour (39.1 %). Natal complications were significantly associated with increased workload during 2nd trimester (mean 58 vs 46 h, p-value 0.040). Doctors belonging to surgical specialty had 2.7 times higher risk of developing at least one natal complication than doctors of medical specialty (95 % Cl: 1.235–5.870). ConclusionLong working hours during pregnancy are associated with antenatal complications among female doctors. Natal complications were only significantly related to long working hours during 2nd trimester of pregnancy, however, female surgeons are more prone to develop natal complications than doctors belonging to medical specialties.

A new classification allowing assessment of instrumental vaginal-birth practices.

Instrumental vaginal birth, a very common intervention in obstetrics, concerns nearly one in eight women in France. Instrumentally assisted vaginal childbirth can be for maternal and/or fetal indications. Although it reduces recourse to caesarean section, it is subject to risks. Practices concerning instrumental birth are disparate, varying among different practitioners, maternity units and countries, and it is essential to be able to evaluate them. Our objective was to create a classification tool of women requiring instrumental birth to facilitate the analysis of practices within our maternity unit as well as to enable temporal and geographical comparisons. We propose a simple and robust classification based on the same principles as Robson's classification. It is made up of seven totally inclusive and mutually exclusive groups. Our classification was refined and validated using the Delphi method by a panel of 14 experts from throughout France, and tested in our maternity unit using data from throughout 2021. The seven clinically relevant groups are based on five obstetric criteria (multiplicity, presentation, gestational age, previous type of birth, induction of labor). To classify each woman in a group, five successive questions are posed in a predefined order. The classification has been validated by the experts with highly satisfactory overall agreement. In order to improve the quality of care, we propose a tool to standardize the evaluation of instrumental vaginal birth practice (called the "Isère classification", after the county where we work in south-eastern France). It will also facilitate the comparison the practices among different maternity units in a network, a country or even among different countries.

Risk factors and management of perinatal genital hematoma: A single, tertiary medical center retrospective study in China.

The goal of this study was to identify the risk factors associated with puerperal genital hematoma (PGHA) and analyze the management strategies employed and the resulting maternal outcomes. This retrospective cohort study examined the pregnant women delivering vaginally with PGHA in Peking University Third Hospital during January 2002 to December 2021. Exploratory data analysis was performed to assess mean, standard deviation (SD), frequency, percentage and percentiles. Independent-samples t-test was performed for continuous variables. Chi-squared test was performed to compare categorical data. A total of 47 women with PGHA were included, and 94 matched controls were enrolled during the same study period. Compared with the control group, labor induction (34.0% vs. 9.6%, P = 0.000) and episiotomy (66.0% vs. 31.9%, P = 0.000) were more frequently performed in PGHA cases. There was a significantly higher incidence of postpartum hemorrhage (PPH) (53.2% vs. 6.4%, P = 0.000) in PGHA patients than in controls. Compared with the patients with <5 cm hematoma, the proportion of prenatal anemia (25.8% vs. 0.0%, P = 0.027) and the incidence of PPH (67.7% vs. 25.0%, P = 0.005) were significantly higher in patients with ≥5 cm hematoma. In comparison, the active period was significantly shorter (3.1 ± 1.9 vs. 5.1 ± 3.0, P = 0.031) in patients with ≥5 cm hematoma. There were significant differences in perineal pain and swelling (31.3% vs. 67.7%, P = 0.017), vulva hematoma (93.8% vs. 48.4%, P = 0.002) and surgical treatment (62.5% vs. 96.8%, P = 0.002). Nearly half of the patients in the ≥5 cm group underwent secondary suture (41.9% vs. 6.3%, P = 0.011). In patients with PGHA detected after more than 2 h, the body mass index was substantially higher (24.5 ± 4.3 vs. 21.4 ± 2.7, P = 0.011), and the weight gain during pregnancy (14.1 ± 4.3 vs. 11.4 ± 3.5, P = 0.021) was significantly lower. Compared with the patients in PGHA without PPH, age (31.7 ± 4.4 vs. 29.4 ± 2.6, P = 0.033) and newborn birth weight (3367 ± 390 g vs. 3110 ± 419 g, P = 0.045) were considerably higher in PGHA cases with PPH, and the platelet count ([182 ± 44] × 109/L vs. [219 ± 51] × 109/L, P = 0.015) was significantly lower. Pregnant women who underwent labor induction and episiotomy had a higher incidence of PGHA. The PGHA-related PPH rate is significantly increased. Active surgical treatment is recommended for patients with ≥5 cm hematoma.

Outpatient labor induction-Exploring future potential by assessing eligibility in a historical cohort.

Labor induction rates have increased over the last decades, and in many high-income countries, more than one in four labors are induced. Outpatient management of labor induction has been suggested in low-risk pregnancies to improve women's birth experiences while also promoting a more efficient use of healthcare resources. The primary aim of this paper was to assess the proportion of women in a historical cohort that would have been eligible for outpatient labor induction with oral misoprostol. Second, we wanted to report safety outcomes and assess efficacy outcomes for mothers and infants in pregnancies that met the criteria for outpatient care. Criteria for outpatient labor induction with oral misoprostol were applied to a historical cohort of women with induction of labor at two Norwegian tertiary hospitals in the period January 1, through July 31, 2021. The criteria included low-risk women with an unscarred uterus expecting a healthy, singleton baby in cephalic position at term. The primary outcome was the proportion of women eligible for outpatient labor induction. Secondary outcomes included reasons for ineligibility and, for eligible women, safety and efficacy outcomes. Overall, 29.7% of the 1320 women who underwent labor induction in a singleton term pregnancy met the criteria for outpatient labor induction. We identified two serious adverse events that potentially could have occurred outside the hospital if the women had received outpatient care. The mean duration from initiation of labor induction to administration of the last misoprostol was 22.4 h. One in 14 multiparous women gave birth within 3 h after the last misoprostol dose. In this historical cohort, three in ten women met the criteria for outpatient management of labor induction with oral misoprostol. Serious adverse events were rare. The average time span from the initiation of labor induction to the last misoprostol was nearly 24 h. This suggests a potential for low-risk women with an induced labor to spend a substantial period of time at home before labor onset. However, larger studies testing or evaluating labor induction with oral misoprostol as an outpatient procedure are needed to draw conclusions.

Isolated fetal umbilical vein varix and the association with intrauterine fetal death and fetal growth restriction: A systematic review, meta-analysis, and nested retrospective cohort study.

To assess the risk of intrauterine fetal death (IUFD) and fetal growth restriction (FGR) in fetuses with an isolated fetal intra-abdominal umbilical vein varix (i-FIUVV). A retrospective cohort study combined with a systematic review and meta-analysis of the literature was performed. In the retrospective cohort study, all singleton fetuses with an i-FIUVV in the fetal medicine units of the Amsterdam UMC (between 2007 and 2023) were analyzed. The primary outcome measures were IUFD and FGR. The sample proportions of IUFD and FGR were depicted as risk percentages. The IUFD proportion was compared to the regional reference population and the FGR proportion was compared to the reported proportions in Europe. The secondary outcome measures were gestational age at diagnosis, initial and maximal FIUVV diameter, fetal monitoring in pregnancy, turbulent flow in the varix, thrombus formation in the varix, induction of labor, gestational age at birth, and birthweight centile. The proportion of fetuses with a birthweight below the 10th centile was compared with that of the regional reference population. The systematic review included all cases from eligible literature published between 2007 and 2023 supplemented by the data of our retrospective cohort study. In the systematic review and meta-analysis, the pooled proportions of IUFD and FGR were assessed in fetuses with i-FIUVV. The retrospective cohort included 43 singletons with an i-FIUVV. The IUFD risk was 0% [Confidence Interval, CI: 0%-8.2%], which did not differ significantly from 0.3% in the reference population, p=1.0. The risk of FGR was 16.3% [CI: 6.8%-30.7%] in the studied population, which is higher than the reported incidence of FGR in Europe ranging from 5%-10%. The proportion of fetuses with birthweights below the 10th centile was higher in our cohort compared with the reference population (23.3 vs. 9.9%, p<0.01). The systematic review included 12 articles, three abstracts, and our current cohort. In total, 513 cases with an i-FIUVV were included. The pooled risk was 0.4% [CI: 0.1%-1.7%] for IUFD and 5.2% [CI: 1.1%-21.3%] for FGR. The mean gestational age at birth did not exceed 39weeks in neither the cohort (38.7weeks) nor the pooled literature (37.6weeks). An i-FIUVV in singletons is not associated with an increased IUFD risk up to 39weeks of gestation but is possibly associated with FGR. The incidence of FGR in our cohort was higher than in the pooled literature (16.3% vs. 5%) but FGR definitions in the included studies varied. The proportion of birthweights below the 10th percentile in our cohort was significantly higher than in the reference group. Thus, based on these findings, we suggest conducting sonographic growth assessments while simultaneously assessing the i-FIUVV. No further monitoring and follow-up are indicated up to 39weeks of gestation. After 39weeks of gestation, data on fetuses with i-FIUVV and their outcomes are lacking.

Early HbA1c Levels as a Predictor of Adverse Obstetric Outcomes: A Systematic Review and Meta-Analysis.

Background: The objective was to assess the association between early HbA1c levels and pregnancy complications and whether this relationship is affected when HbA1c thresholds are greater than or less than 39 mmol/mol (5.7%). Methods: Electronic searches of the MEDLINE and EMBASE databases up to October 2022 were conducted. We included retrospective and prospective observational studies. The inclusion criteria were as follows: HbA1c measurements taken at <20 weeks' gestation, singleton pregnancy, and no pre-existing diabetes mellitus. Results: We assessed the certainty of the evidence with the GRADE system. We determined the proportion of patients in each group who met the criteria for obstetrical outcomes and pooled data into two subgroups according to the HbA1c threshold: <39 mmol/mol or >39 mmol/mol (5.7%). Sixteen studies with a total of 43,627 women were included. An association between elevated early HbA1c levels and pre-eclampsia, large for gestational age (LGA), macrosomia, and preterm delivery (RR 2.02, 95% CI 1.53-2.66; RR 1.38, 95% CI 1.15-1.66; RR 1.40, 95% CI 1.07-1.83; and RR 1.67, 95% CI 1.39-2.0, respectively) was shown, with a moderate-high grade of certainty. According to the subgroup analysis of all studies, LGA, pre-eclampsia, and labour induction were associated with elevated HbA1c levels only in studies using an HbA1c threshold >39 mmol/mol (5.7%). The association between HbA1c levels and premature birth was statistically significant in studies using both higher and lower HbA1c thresholds. Conclusions: Women with high early HbA1c levels below the range of diabetes presented an increased risk of pregnancy complications such as macrosomia, LGA, and pre-eclampsia. An early HbA1c threshold of >39 mmol/mol (5.7%) showed the strongest association with pregnancy complications.

Immune cells at the feto-maternal interface: Comprehensive characterization and insights into term labor

Immune cells at the feto-maternal interface play an important role in pregnancy; starting at implantation, maintenance of pregnancy, and parturition. The role of decidual immune cells in induction of labor still needs to be understood. Published reports on this topic show heterogeneity in methods of cell isolation, assay, analysis and cellular characterization making it difficult to collate available information in order to understand the contribution of immune cells at term leading to parturition. In the present study, available literature was reviewed to study the differences in immune cells between the decidua basalis and decidua parietalis, as well as between immune cells in term and preterm labor. Additionally, immune cells at the decidua parietalis were isolated from term not in labor (TNL) or term in labor (TL) samples and characterized via flow cytometry using a comprehensive, high-dimensional antibody panel. This allowed a full view of immune cell differences without combining multiple studies, which must include variation in isolation and analysis methods, for more conclusive data. The ratio of cells found in decidua parietalis in this study generally matched those reported in the literature, although we report a lower percentage of natural killer (NK) cells at term. We report that CD4 expression on CD8- NK cells decreased in term labor compared to not in labor samples, suggesting that natural killer cells may be migrating to other sites during labor. Also, we report a decrease in CD38 expression on CD8+ CD57+ T cells in labor, indicative of cytotoxic T cell senescence. Our study provides a comprehensive status of immune cells at the decidua-chorion interface at term.

Comparison of digital and speculum-guided methods of transcervical Foley catheter insertion in primigravida undergoing cervical ripening at term gestation: a noninferiority randomized clinical trial

BackgroundFoley catheter insertion is frequently utilized for cervical ripening during the induction of labour. However, the insertion failure, safety, maternal side effects, complications and satisfaction of digital compared to speculum-guided Foley catheter placement have not been evaluated in a large trial involving primigravida. ObjectivesThe study aimed to compare the insertion failure rate of digital and speculum-based transcervical Foley catheter placement in primigravida. The co-primary outcome was insertion-associated pain. The secondary outcomes were time required for successful insertion, maternal satisfaction, and maternal complications within 24 hours of Foley insertion. MethodsThis randomized, open-label, parallel-arm, non-inferiority clinical trial was performed in a large tertiary care university hospital. Primigravida >18 years of age with term gestation (≥37 weeks) were included in this study. Additional inclusion criteria for enrolment in this study were singleton pregnancy with a cephalic presentation, intact membrane, Bishop score ≤5 and reassuring pre-induction foetal heart rate tracing. All women planned for cervical ripening were assessed for eligibility and were randomized into digital or speculum arms. Foley catheter insertion was performed in a supine lithotomy position. Vaginal and cervical cleaning were performed before insertion. A 22-French Foley balloon catheter was guided digitally or via speculum to position the bulb at the level of the internal os using water-soluble lubricant. Insertion-associated pain was measured using visual numeric rating scale (VNRS) and maternal satisfaction was assessed using a set of questions. Results469 pregnant women were assessed for eligibility, and 446 patients were enrolled and randomized. The median age of the parturients was 24 (19-40) and 24 (18-38) years, respectively. The body mass index, gestational age at randomization, incidence of post-dated pregnancy and pre-randomization Bishop scores were comparable. Insertion failure was observed in 24 (10.8%) and 17 (7.6%) of women in digital and speculum arm, respectively (RR= 1.41; 95% CI, 0.78-2.55; P=0.25). Requirements of more than one attempt (5.4% vs 3.6%) followed by change in hands (3.6% vs 2.7%) were the most common reasons for insertion failure. The median (interquartile range) VNRS was comparable (6.00 (2-9) vs 5.00 (2-10); p=0.15). The time taken for successful insertion was similar (58 (12-241) vs 54 (10-281); p=0.30). 9.4% and 10.8% of women required additional methods of cervical ripening. More women in the speculum group (41.7% vs 33.2%; P=0.06) felt a medium level of discomfort than digital group. ConclusionInsertion failure and insertion-related pain in the digital approach were comparable to the speculum-guided approach for transcervical Foley catheter insertion in primigravida for cervical ripening. Nevertheless, maternal satisfaction was higher in the digital group due to a lesser level of discomfort.

A Comparative Study of Vaginal, Sublingual, and Buccal Misoprostol in Induction of Labor in Term Pregnancy

A Comparative Study of Vaginal, Sublingual, and Buccal Misoprostol in Induction of Labor in Term Pregnancy

Time matters: Cervical ripening balloon for 6 versus 12 h-Retrospective comparison between two protocols.

Recently, two randomized controlled trials compared removal of cervical ripening balloon (CRB) after 6 versus 12 h. Their results showed similar Bishop score changes in both groups and a shorter time to delivery in the 6-h group. Neither of the studies was powered to show difference in mode of delivery. The aim of this study was to compare mode of delivery when the CRB was removed after 6 versus 12 h. A historical control study comparing induction of labor with a CRB between two time periods, one in which the CRB was removed after 12 h (12-h group), and the other in which it was removed after 6 h (6-h group). We included term pregnancies with a singleton fetus in vertex presentation. We excluded patients with a previous cesarean delivery, failed ripening with prostaglandins prior to CRB insertion, and any contraindication for vaginal delivery. The primary outcome was mode of delivery. Secondary outcomes included delivery within 24 h and other maternal and neonatal outcomes. We included 1704 patients, 914 in the 12-h group, and 717 in the 6-h group. Removal after 6 h was associated with a lower rate of cesarean and instrumental deliveries (28.6% vs 22.5%, and 12% vs 6.2%, respectively) and a higher rate of vaginal delivery within 24 h. All differences were statistically significant. Removing a cervical ripening balloon after 6 rather than 12 h is associated with reduced cesarean and instrumental delivery rates, and should be considered as a reasonable, and potentially superior alternative in labor induction protocols with intracervical ripening balloon.

Implementation of sonopartogram: multicenter feasibility study.

Well-established clinical practice for assessing progress in labor involves routine abdominal palpation and vaginal examination (VE). However, VE is subjective, poorly reproducible and painful for most women. In this study, our aim was to evaluate the feasibility of systematically integrating transabdominal and transperineal ultrasound assessment of fetal position, parasagittal angle of progression (psAOP), head-perineum distance (HPD) and sonographic cervical dilatation (SCD) to monitor the progress of labor in women undergoing induction of labor (IOL). We also aimed to determine if ultrasound can reduce women's pain during such examinations. Women were recruited as they presented for IOL in three maternity units. Ultrasound assessments were performed in 100 women between 37 + 0 and 41 + 6 weeks' gestation. A baseline combined transabdominal and transperineal scan was performed, including assessment of fetal biometry, umbilical artery and fetal middle cerebral artery Doppler, amniotic fluid index, fetal spine and occiput positions, psAOP, HPD, SCD and cervical length. Intrapartum scans were performed instead of VE, unless there was a clinical indication to perform a VE, according to protocol. Participants were asked to indicate their level of pain by verbally giving a pain score between 0 and 10 (with 0 representing no pain) during assessment. Repeated measures data were analyzed using mixed-effect models to identify significant factors that affected the relationship between psAOP, HPD, SCD and mode of delivery. A total of 100 women were included in the study. Of these, 20% delivered by Cesarean section, 65% vaginally and 15% by instrumental delivery. There were no adverse fetal or maternal outcomes. A total of 223 intrapartum ultrasound scans were performed in 87 participants (13 women delivered before intrapartum ultrasound was performed), with a median of two scans per participant (interquartile range (IQR), 1-3). Of these, 76 women underwent a total of 151 VEs with a median of one VE per participant (IQR, 0-2), with no significant difference between vaginal- or Cesarean-delivery groups. After excluding those with epidural anesthesia during examination, the median pain score for intrapartum scans was 0 (IQR, 0-1) and for VE it was 3 (IQR, 0-6). Cesarean delivery was significantly associated with a slower rate of change in psAOP, HPD and SCD. Comprehensive transabdominal and transperineal ultrasound assessment can be used to assess progress in labor and can reduce the level of pain experienced during examination. Ultrasound assessment may be able to replace some transabdominal and vaginal examinations during labor. © 2024 The Authors.

Pregnancy-related cardiac outcomes among patients with congenital heart disease after formalization of a cardio-obstetrics program

The prevalence of pregnant patients with congenital heart disease (CHD) is increasing, and these patients are at high risk for cardiac morbidity. This study aimed to examine the pregnancy outcomes in patients with congenital heart disease before and after the establishment of formal cardio-obstetrics collaboration between adult congenital heart disease and maternal-fetal medicine programs. This was a retrospective cohort study of pregnant patients with congenital heart disease from 2002 to 2020 at a single urban academic institution in the United States. This study included patients with a singleton pregnancy who continued a pregnancy beyond 20 weeks of gestation. The primary outcome was a composite adverse maternal cardiac outcome, compared before (2002-2010) and after (2011-2020) the program. The secondary outcomes included gestational age at delivery, mode of delivery, rate of labor induction, use of diuresis after delivery, and a composite maternal morbidity outcome. The number of pregnant patients with congenital heart disease increased after formalization of the cardio-obstetrics program (200 [postprogram group] vs 84 [preprogram group]; 0.48% of all deliveries in the postprogram group vs 0.25% of all deliveries in the preprogram group; P<.001). The postprogram group was more likely to undergo labor induction than the preprogram group (126 [63%] vs 34 [41%], respectively; P<.001). There were fewer patients in the postprogram group than in the preprogram group who were New York Heart Association class II to IV (23 [12%] vs 17 [22%], respectively; P=.04) or with systemic ventricular dysfunction (8 [4%] vs 12 [16%], respectively; P=.001). There was no difference in the primary outcome (38 [19%] in the postprogram group vs 14 [17%] in the preprogram group; P=.64), even after adjusting for confounders, including New York Heart Association class >I and systemic ventricular dysfunction (adjusted odds ratio, 2.3; 95% confidence interval, 0.96-5.4). Patients in the postprogram group were more likely to receive diuresis after delivery than patients in the preprogram group, even in the absence of heart failure or pulmonary edema (9 [4.5%] vs 0 [0.0%], respectively; P=.04). In the period after the establishment of a formal cardio-obstetrics program between adult congenital heart disease and maternal-fetal medicine, the number of patients with congenital heart disease delivering at our institution increased significantly. Overall, fewer patients entered pregnancy with advanced-stage heart failure or systemic ventricular dysfunction, possibly suggesting improved prepregnancy cardiac care or improved preconception counseling. Composite maternal cardiac outcomes were similar, but the rates of postpartum diuresis increased significantly, suggesting increased attention to volume status in the postpartum period. Formalized collaboration between congenital heart disease and maternal-fetal medicine may help better optimize patients' care before conception, during pregnancy, and after delivery.

INPATIENT VS OUTPATIENTS LABOR INDUCTION : A COMPREHENSIVE SYSTEMATIC REVIEW

Background: Labor induction can take a long period, anywhere from a few hours to several days, especially in nulliparous women. Worldwide, the use of mechanical or pharmaceutical treatments for outpatient cervical ripening is becoming more and more common. Aims : This systematic review is to review the comparison of outpatient with inpatient labor induction. Methods: By comparing itself to the standards set by the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020, this study was able to show that it met all of the requirements. So, the experts were able to make sure that the study was as up-to-date as it was possible to be. For this search approach, publications that came out between 2014 and 2024 were taken into account. Several different online reference sources, like Pubmed and SAGEPUB, were used to do this. It was decided not to take into account review pieces, works that had already been published, or works that were only half done. Result: In the PubMded database, the results of our search brought up 83 articles, whereas the results of our search on SAGEPUB brought up 605 articles, our search on SCIENCE DIRECT brought up 470 articles. The results of the search conducted for the last year of 2014 yielded a total 17 articles for PubMed, 155 articles for SAGEPUB and 122 articles for SCIENCE DIRECT. In the end, we compiled a total of 8 papers, 4 of which came from PubMed, 2 of which came from SAGEPUB and 2 of which came from SCIENCE DIRECT. We included eight research that met the criteria. Conclusion: In summary, in modern obstetrics, when labor is being induced in an increasing percentage of pregnancies, outpatient induction for low-risk women offers a safe, practical, and successful alternative to hospital induction. This is especially true in places with abundant resources. It should be given more widespread consideration.

Prenatal transposition of great arteries diagnosis and management: a Chinese single-center study.

This study aimed to assess the diagnostic value of prenatal echocardiography for identifying transposition of the great arteries (TGA) during pregnancy and evaluating the associated outcomes. We conducted a retrospective analysis of 121 prenatally diagnosed patients with TGA at our hospital between January 2012 and September 2022. This analysis included prenatal ultrasound, prenatal screening, clinical management and follow-up procedures. Among the 103 fetuses considered in the study, 90 (87.4%) were diagnosed with complete transposition of the great arteries (D-TGA), while 13 (12.6%) exhibited corrected transposition of the great arteries (CC-TGA). Diagnoses were distributed across the trimester, with 8 D-TGA and 2 CC-TGA patients identified in the first trimester, 68 D-TGA patients and 9 CC-TGA patients in the second trimester, and 14 D-TGA and 2 CC-TGA patients referred for diagnosis in the third trimester. Induction of labour was pursued for 76 D-TGA patients (84.4%) and 11 CC-TGA patients (84.6%), and 14 D-TGA patients (15.6%) and 2 CC-TGA patients (15.4%) continued pregnancy until delivery. Among the D-TGA patients, 9 fetuses (10.0%) underwent surgery, two of which were inadvertent fatality, while the remaining seven experienced positive outcomes. Additionally, seven TGA patients received palliative care, leading to four fatalities among D-TGA patients (5.2%), whereas 1 D-TGA patients and 2 CC-TGA patients survived. This study underscores the feasibility of achieving an accurate prenatal diagnosis of TGA during early pregnancy. The utility of prenatal ultrasound in the development of personalized perinatal plans and the application of multidisciplinary treatment during delivery are conducive.

Cardiac remodeling in patients with atrial fibrillation reversing bradycardia-induced cardiomyopathy: A case report

BACKGROUND Bradycardia-induced cardiomyopathy (BIC), which is a disease resulting from bradycardia, is characterized by cardiac chamber enlargement and diminished cardiac function. The correction of bradycardia can allow for significant improvements in both cardiac function and structure; however, this disease has been infrequently documented. In this case, we conducted a longitudinal follow-up of a patient who had been enduring BIC for more than 40 years to heighten awareness and prompt timely diagnosis and rational intervention. CASE SUMMARY A woman who presented with postactivity fatigue and dyspnea was diagnosed with bradycardia at the age of 7. Since she had no obvious symptoms, she did not receive any treatment to improve her bradycardia during the 42-year follow-up, except for the implantation of a temporary pacemaker during labor induction surgery. As time progressed, the patient's heart gradually expanded due to her low ventricular rate, and she was diagnosed with BIC. In 2014, the patient developed atrial fibrillation, her ventricular rate gradually increased, and her heart shape gradually returned to normal. This report describes the cardiac morphological changes caused by the heart rate changes in BIC patients older than 40 years, introduces another possible outcome of BIC, and emphasizes the importance of early intervention in treating BIC. CONCLUSION BIC can induce atrial fibrillation, causing an increased ventricular rate and leading to positive cardiac remodeling.

Routine vaginal examination to assess labor progress at 8 compared to 4 hours after early amniotomy following Foley balloon ripening in the labor induction of multiparas: a randomized trial

BackgroundVaginal examination to monitor progress in labor is recommended at least every 4 hours but it can cause pain and embarrassment to women. Trial data is limited on the best intensity for vaginal examination. Vaginal examination is not needed for oxytocin dose titration after amniotomy has been performed and oxytocin infusion started. The Foley balloon commonly ripens the cervix without strong contractions; amniotomy and oxytocin infusion is usually required to drive labor. ObjectiveTo evaluate the first vaginal examination at 8 vs 4 hours after amniotomy-oxytocin following Foley ripening in multiparous labor induction. MethodsA randomized controlled trial was conducted from October 2021 to September 2022 in University Malaya Medical Center. Multiparas at term were recruited at admission for labor induction. Participants were randomized to a first routine vaginal examination at 8 or 4 hours after Foley balloon ripening and amniotomy. Titrated oxytocin infusion was routinely commenced after amniotomy to initiate contractions. The two primary outcomes were the time from amniotomy to delivery (non-inferiority hypothesis) and maternal satisfaction (superiority hypothesis). Data were analyzed with the Student t-test, Mann-Whitney U test, Chi square test (or Fisher exact test) as suitable for the data. Results204 women were randomized, 102 to each arm. Amniotomy to birth interval was mean±standard deviation 4.97±2.47 vs 5.79±3.17, mean difference -0.82, 97.5% CI (-1.72 to 0.08) hours p=0.041 (Bonferroni correction), which was non-inferior within the pre-specified 2 hour upper margin and maternal satisfaction score with allocated labor care was median[interquartile range] 9[8-9] vs 8[7-9] p=0.814 (11-point 0-10 NRS) for 8 vs 4 hours arms respectively. Oxytocin infusion to birth interval difference was also non-inferior within the 97.5% CI (-1.59 to 0.23) margin of 2 hours. Of the maternal outcomes, amniotomy to first vaginal examination intervals were 3.9±1.8 vs 3.4±1.3hours p=0.026 and number of vaginal examinations was 2[2-3] vs 3[2-3.25] p<0.001 for 8 vs 4 hours arms respectively. For the 8 hours arm, first vaginal examination was less likely to be as scheduled and more likely to be indicated by sensation to bear down (p<0.001) and epidural analgesia rate was lower 13/102 (12.7%) vs 28/102 (27.5%) RR 0.46 95% CI 0.26–0.84 p=0.009. Other outcomes of mode of delivery, indications for cesarean and delivery blood loss were not different. Neonatal outcomes were not different. ConclusionRoutine first vaginal examination at 8 hours compared to 4 hours is non-inferior for the time to birth but does not improve maternal satisfaction.

Fetal Surveillance From 39 Weeks’ Gestation to Reduce Stillbirth in South Asian–Born Women

ABSTRACT Women of South Asian background are known to have higher rates of stillbirth than women in other high-income countries, such as Australia or the United Kingdom. To reduce the rate of stillbirth, leading societies recommend antenatal fetal monitoring or induction of labor (IOL) at 41 weeks of gestation regardless of race/ethnicity. However, at 41 weeks' gestation, the risk of stillbirth for South Asian–born women is already up to 5 times higher than for Australian-born women. Initially, the UK National Institution for Health and Care Excellence recommended that all South Asian women undergo IOL earlier, at 39 weeks of gestation. However, this recommendation was criticized as being racist, and perpetuating the myth that race plays a factor in poor outcomes, so it was amended to state that South Asian–born women might benefit from additional monitoring and support. Still, there is no evidence to support this guidance. In July 2017, the State of Victoria in Australia implemented a new clinical guideline to provide South Asian women with biweekly cardiotocography and amniotic fluid measurement at 39 weeks of gestation. The aim of this study was to assess the impact of the new clinical guideline on the rates of stillbirth and select pregnancy outcomes for South Asian women. This was a cohort study that included women with singleton pregnancies who gave birth at term or beyond at a university- affiliated teaching health service located in 3 metropolitan areas in Australia from January 1, 2016, to December 31, 2020. Women were classified as South Asian born if they self-identified as being from Afghanistan, Bangladesh, Bhutan, India, Iran, the Maldives, Nepal, Pakistan, or Sri Lanka. The timeframe between January 1, 2016, and June 30, 2017, represented the period before the change in practice for fetal monitoring for South Asian women; the timeframe between July 1, 2017, and December 31, 2020, represented the period after. Although the new practice was applied to South Asian–born women in the second timeframe, fetal monitoring at 41 weeks was applied to all other women. The primary outcome was stillbirth at the onset of or during labor at 37 weeks and 39 weeks of gestation. The secondary outcomes included neonatal death at &lt;7 days, admission to the special care nursery or neonatal intensive care, Apgar score &lt;7 at 5 minutes, infant birthweight, gestation of birth, IOL, and mode of birth. A total of 3506 South Asian women gave birth before the change in practice, whereas 8532 gave birth postimplementation. The rate of stillbirth at 37 weeks' gestation for South Asian–born women was 2.3 per 1000 births—a 2.6-fold higher rate than for other women (0.9 per 1000 births; P = 0.06). After the change in practice, the rate of stillbirth fell by 64% for South Asian–born women (95% confidence interval, 87%–2%; P = 0.047). The association was stronger when the results were restricted to births after 39 weeks of gestation. Also, after the change in practice, reduced rates for early neonatal death (3.1 per 1000 vs 1.3 per 1000; P = 0.03) and admission to the special care nursery (16.5% vs 11.1%; P &lt; 0.001) were observed. The median gestation of birth for South Asian–born women was 39+3 weeks preimplementation compared with 39+2 weeks postimplementation, a difference of 1 day. The rate of IOL for South Asian–born women was 4.9% higher than other women (95% confidence interval, 1.3%–8.5%; P = 0.008). However, no significant difference was observed between the 2 groups in the rate of IOL per month after the change in practice, nor across the other secondary outcomes. In conclusion, fetal monitoring starting at 39 weeks' gestation among South Asian–born women reduced the rate of stillbirth, neonatal death, and admission to the special care nursery compared with previous guidelines to begin monitoring at 41 weeks.
