Abstract
BACKGROUND Evidence regarding the type and rate of intravenous (IV) fluid administration during labor is still inconclusive and the studies assessing the impact of IV fluids had mixed results. OBJECTIVES To evaluate the effects of IV fluids at an infusion rate of 250 mL/h as compared with 125 mL/h on labor outcomes in nulliparous women. SEARCH STRATEGY We searched six databases for relevant studies through a search strategy containing the relevant keywords "IV hydration", "IV fluids", and "labor" from the inception of these databases to May 1, 2023, without any applied restrictions. SELECTION CRITERIA Search results were imported to Covidence for screening of eligible articles for this review. Randomized controlled trials (RCTs) assessing the impact of IV fluids at 250 mL/h on the outcomes of labor in nulliparous women at term (>37 weeks) as compared with 125 mL/h were included only. DATA COLLECTION AND ANALYSIS Data regarding the characteristics of included studies, participant's baseline characteristics, and concerned outcomes were collected in an Excel spreadsheet and all the concerned outcomes were pooled as risk ratios (RR) or mean difference (MD) with 95% confidence interval (CI) in the meta-analysis models using RevMan 5.4. MAIN RESULTS Pooled data from 11 RCTs with 1815 patients showed that 250 mL/h infusion rate had a significant reduction in cesarean section rate (RR 0.70, 95% CI 0.56-0.88, P = 0.002), the first stage of labor duration (MD -46.97, 95% CI -81.79 to -12.14, P = 0.008), the second stage of labor duration (MD -2.69, 95% CI -4.34 to -1.05, P = 0.001), prolonged labor incidence (RR 0.72, 95% CI 0.58-0.89, P = 0.003), as compared with 125 mL/h. Also, the vaginal delivery rate (RR 1.07, 95% CI 1.02-1.12, P = 0.009) was higher with a 250 mL/h infusion rate. CONCLUSION IV fluids at an infusion rate of 250 mL/h during labor in nulliparous women decreased the cesarean delivery rate, increased the vaginal delivery rate, shortened the first and second-stage labor duration, decreased the incidence of prolonged labor as compared with 125 mL/h. These findings suggest enhanced labor progression and a lower risk of labor complications with higher infusion rates. However, future research involving a more diverse population and exploring the potential benefits of combining IV infusion rates with other interventions, such as adding dextrose or less restrictive oral intake during labor, is needed.

Abstract
OBJECTIVES To evaluate expectant compared to immediate return to hospital upon outpatient Foley catheter expulsion predicated on maternal satisfaction and amniotomy-titrated oxytocin infusion to delivery interval. METHODS This randomized trial was conducted in a tertiary university hospital in Malaysia from September 2020 to February 2022. A total of 330 nulliparous women at term with unripe cervices (Bishop score ≤5), singleton viable fetus in cephalic presentation, reassuring preinduction fetal heart rate tracing and intact membranes who underwent planned outpatient Foley catheter induction of labor (IOL) were included. Women were randomized to expectant or immediate return to hospital if the Foley was spontaneously expelled at home before their scheduled hospital admission the following day. Primary outcomes were amniotomy-titrated oxytocin infusion to delivery interval and maternal satisfaction on the induction process (assessed by 0-10 visual numerical rating scale [VNRS]). RESULTS Amniotomy-titrated oxytocin infusion to delivery interval was 8.7 ± 4.1 versus 8.9 ± 3.9 h, P = 0.605 (mean difference - 0.228 95% CI: -1.1 to +0.6 h) and maternal satisfaction VNRS score was median (interquartile range) 8 (7-9) versus 8 (7-9), P = 0.782. Early return to hospital rates were 37/165 (22.4%) versus 72/165 (43.6%), RR 0.51 (95% CI: 0.37-0.72), P ≤ 0.001, Cesarean delivery rates were 80/165 (48.5%) versus 80/165 (48.5%), RR 1.00 (95% CI: 0.80-1.25), P = 1.00 and duration of hospital stay was 54.4 ± 22.9 versus 56.7 ± 22.8 h, P = 0.364 for the expectant versus immediate return groups respectively. CONCLUSION In outpatient Foley catheter IOL, expectant compared to immediate return to hospital following Foley dislodgement results in similarly high maternal satisfaction. The amniotomy-titrated oxytocin to delivery duration is non-inferior with expectant management.

Abstract
The initial ovulatory response during synchronization programs is often low in dairy heifers, largely due to follicular dynamics and hormonal dynamics. Specifically, the progesterone concentration (P4) at the time of the first GnRH treatment in a breeding program can influence the LH response, often resulting in a suboptimal ovulatory response. The objective of this study was to determine the effect of the highest label dose 200 μg (100 μg vs. 200 μg) of GnRH (50 μg gonadorelin hydrochloride per mL; Factrel®; Zoetis Inc. Madison, NJ) at the first GnRH of a 6-d CoSynch plus P4 device program on ovulatory response and pregnancy per AI (P/AI) in first service in Holstein heifers. A total of 1308 Holstein heifers were randomly allocated at the beginning of a 6-d CIDR-Synch program, Day 0, to receive either i.m. treatment of 100 μg (2CC, n = 655) or 200 μg (4CC, n = 653) of GnRH. Also, at Day 0, heifers received an intravaginal insert with 1.38 g of P4 (Eazi-Breed CIDR® Cattle Insert; Zoetis Inc., Madison, NJ). On Day 6, the insert was removed, and i.m. treatment of 25 mg of PGF2α (12.5 mg dinoprost tromethamine/mL; Lutalyse® HighCon Injection Zoetis) was administered. On Day 7, a second i.m. treatment of 25 mg of PGF2α was given, followed on Day 9 by concurrent i.m. treatment of 100 μg of GnRH and timed AI (TAI). A subset of 396 heifers had their ovaries scanned to evaluate ovulatory response, and blood samples were collected to measure the serum concentration of P4 at Day 0 and Day 6 of the study. The P4 concentrations at Day 0 were categorized as Low (≤3ng/mL) or High (>3ng/mL). The ovulatory response was greater for heifers receiving 4CC than 2CC at Day 0 (54.7% vs. 42.8%). The ovulatory response was greater for Low P4 than High P4 at Day 0 (54.3% vs. 37.8%). However, there was not an interaction between treatment and P4 concentrations (Low P4 2CC = 48.6% vs. High P4 2CC = 30.0%; Low P4 4CC = 60.0% vs. High P4 4CC = 45.5%). The ROC curve analysis indicates that P4 concentrations at Day 0 treatment could predict the ovulatory response, although the area under the curve was only 0.6. As expected, heifers that ovulated had increased P/AI (No = 55.6% vs. Yes = 67.7%); however, there was no effect of treatment on P/AI (2CC = 63.3% vs. 4CC = 59.6%), nor interactions between treatment and ovulation and treatment and P4 (HIGH vs LOW) for pregnancy outcomes. In summary, P4 concentration and increasing the dose of GnRH at Day 0 positively impacted ovulatory response in Holstein heifers. However, there was no interaction between treatment and P4 on ovulation and no subsequent impact of GnRH dose on P/AI.

Abstract
Nulliparous (pregnant women who are giving birth for the first time) and multiparous (women who have multiple children) may have different concerns, which may be associated with risk of antenatal depression. This study aims to examine the role of social support and stressful life events as risk factors for antenatal depression in nulliparous and multiparous women. The sample included 1,524 pregnant women recruited from an obstetrics setting at the end of the first trimester of pregnancy from two Spanish tertiary-care public hospitals. The sample completed the Patient Health Questionnaire (PHQ-9), and the "social support" and "stressful life events" subscales of the Postpartum Depression Predictor Inventory-Revised (PDPI-R). Nulliparous women reported a lower prevalence of depressive symptoms (15.6 percent) compared to multiparous mothers (20.1 percent). In both groups, marriage/partner problems (NP: β = 0.178, p < .01 vs MP: β = 0.164, p < .01) and a perceived lack of instrumental support from friends (NP: β = -0.154, p < .01 vs MP: β = -0.154, p < .01) were significant risk factors for antenatal depression. However, nulliparous women have more risk factors such as unemployment (β = 0.096, p < .05), job change (β = 0.127, p < .01), financial problems (β = 0.145, p < .01) and lack of instrumental support from partner (β = -0187, p < .01). For multiparous women, moving (β = 0.080, p < .05) and lack of instrumental support from family (β = -0.151, p < .01) were risk factors. These results suggest the critical need for screening and designing preventive interventions adapted and taking into consideration parity to provide more effective health care during pregnancy.

Abstract
AIM This study aimed to clarify the factors influencing preeclampsia (PE) development in nulliparous Japanese women and to develop a PE prediction model using second trimester sonographic and clinical data readily available to obstetricians. METHODS This historical cohort study examined the obstetric records of nulliparous women who delivered at Yamanashi Prefectural Central Hospital from January 2019 to May 2023. A model was constructed to predict the PE development rate, with a focus on 796 nulliparous women. The assessed outcome was PE, excluding superimposed PE. Data on maternal age, assisted reproductive technology, mean arterial pressure, uterine artery notching, and umbilical artery resistance index were extracted. Multivariable logistic regression analysis was conducted on these five factors. RESULTS The incidence of PE was 4.3% (34/796). Multivariable analysis indicated significant odds ratios for the association of PE with mean arterial pressure (adjusted odds ratio: 1.06, 95% confidence interval: 1.03-1.10) and uterine artery notching (adjusted odds ratio: 6.28, 95% confidence interval: 2.82-14.0) in nulliparous women. The PE prediction formula was established as follows: Probability of PE development (%) = (odds/1 + odds) × 100, odds = ex and x = -11.3 + 0.039 × maternal age (years) + 0.91 × assisted reproductive technology + 0.061 × mean arterial pressure (mmHg) + 1.84 × uterine artery notching + 1.84 × umbilical artery resistance index. The sensitivity and specificity of this model were 58.8% and 84.5%, respectively (area under the curve: 0.79). CONCLUSIONS This study is the first to provide a prediction formula targeting the Japanese population. Our specialized model for nulliparous women could guide obstetricians to educate women regarding the precise prospect of PE development.

Abstract
Introduction Pelvic organ prolapse (POP) is a significant health concern for young Nepali women, with potential risk factors including pelvic floor trauma from vaginal delivery and heavy lifting. The prevalence of symptomatic POP (SPOP) among nulliparous women in Nepal is 6%, while the general population of Nepali women aged 15-49 years reports a prevalence of 7%. Surprisingly, the average age of SPOP onset in Nepal is 27 years, challenging the assumption that postmenopausal age and vaginal delivery are the sole risk factors. This study aims to investigate the influence of increased intra-abdominal pressure (IAP) during lifting tasks on pelvic organ descent in Nepali women across different menstrual cycle stages. Methods The study included 22 asymptomatic Nepali women aged 18-30 years who regularly engage in heavy lifting. Intra-abdominal pressure was measured intra-vaginally during typical and simulated lifting tasks, which encompassed various scenarios such as ballistic lifting, ramped lifting, and pre-contraction of pelvic floor muscles, as well as coughing, Valsalva maneuver, and pelvic floor contractions. Pelvic floor displacement was recorded using transperineal ultrasound during menstruation, ovulation, and the mid-luteal phase. Results Results indicated that pelvic floor displacement was greater during menstruation than ovulation when performing a simulated ballistic lifting task (6.0 ± 1.6 mm vs. 5.1 ± 1.5 mm, p = 0.03, d = 0.6). However, there was no significant difference in pelvic floor displacement during lifting when the pelvic muscles were pre-contracted. Conclusion These findings suggest that lifting heavy loads during menstruation may increase the risk of stretching and injuring pelvic floor supportive tissues, potentially contributing to SPOP in young Nepali women. Pre-contracting pelvic floor muscles during lifting tasks may offer a protective effect. Understanding these factors could aid in developing targeted preventive measures and raising awareness about the impact of heavy lifting on pelvic floor health among Nepali women.

Abstract
BACKGROUND The incidence of second stage cesarean delivery has been rising globally because of the failure or the anticipated difficulty of performing instrumental delivery. Yet, the best way to interpret the figure and its optimal rate remain to be determined. This is because it is strongly influenced by the practice of other 2 modes of birth, namely cesarean delivery performed before reaching the second stage and assisted vaginal birth during the second stage. In this regard, a bubble chart that can display 3-dimensional data through its x-axis, y-axis, and the size of each plot (presented as a bubble) may be a suitable method to evaluate the relationship between the rates of these 3 modes of births. OBJECTIVE This study aimed to conduct an epidemiologic study on the incidence of second stage cesarean deliveries rates among >300,000 singleton term births in 10 years from 8 obstetrical units and to compare their second stage cesarean delivery rates in relation to their pre-second stage cesarean delivery rates and assisted vaginal birth rates using a bubble chart. STUDY DESIGN The territory-wide birth data collected between 2009 and 2018 from all 8 public obstetrical units (labelled as A to H) were reviewed. The inclusion criteria were all singleton pregnancies with cephalic presentation that were delivered at term (≥37 weeks' gestation). Pre-second stage cesarean delivery rate was defined as all elective cesarean deliveries and those emergency cesarean deliveries that occurred before full cervical dilatation was achieved as a proportion of the total number of births. The second stage cesarean delivery rate and assisted vaginal birth rate were calculated according to the respective mode of delivery as a proportion of the number of cases that reached full cervical dilatation. The rates of these 3 modes of births were compared among the parity groups and among the 8 units. Using a bubble chart, each unit's second stage cesarean delivery rate (y-axis) was plotted against its pre-second stage cesarean delivery rate (x-axis) as a bubble. Each unit's second stage cesarean delivery to assisted vaginal birth ratio was represented by the size of the bubble. RESULTS During the study period, a total of 353,434 singleton cephalic presenting term pregnancies were delivered in the 8 units, and 180,496 (51.1%) were from nulliparous mothers. When compared with the multiparous group, the nulliparous group had a significantly lower pre-second stage cesarean delivery rate (18.58% vs 21.26%; P<.001) but a higher second stage cesarean delivery rate (0.79% vs 0.22%; P<.001) and a higher assisted vaginal birth rate (17.61% vs 3.58%; P<.001). Using the bubble of their averages as a reference point in the bubble chart, the 8 units' bubbles were clustered into 5 regions indicating their differences in practice: unit B and unit H were close to the average in the center. Unit A and unit F were at the upper right corner with a higher pre-second stage cesarean delivery rate and second stage cesarean delivery rate. Unit D and unit E were at the opposite end. Unit C was at the upper left corner with a low pre-second stage cesarean delivery rate but a high second stage cesarean delivery rate, whereas unit G was at the opposite end. Unit C and unit G were also in the extremes in terms of pre-second stage cesarean delivery to assisted vaginal birth ratio (0.09 and 0.01, respectively). Although some units seemed to have very similar second stage cesarean delivery rates, their obstetrical practices were differentiated by the bubble chart. CONCLUSION The second stage cesarean delivery rate must be evaluated in the context of the rates of pre-second stage cesarean delivery and assisted vaginal birth. A bubble chart is a useful method for analyzing the relationship among these 3 variables to differentiate the obstetrical practice between different units.

For maximum productivity in a dairy farm, the earliest and the most accurate detection of pregnancy is essential. The aim of this study was to determine the efficacy of expression patterns of miR-26a, and serum Preimplantation Factor (PIF) levels for pregnancy diagnosis during the early pregnancy in nulliparous and multiparous cows. A total of 60 cows (30 nulliparous and 30 multiparous Holstein cows) were enrolled in the study. Blood samples were collected for miR-26a on days 8 and 16 (D8 and D16), and for the PIF on days 10 and 20 (D10 and D20) following insemination (D0). Pregnancies were determined by ultrasonography on the 28th day after insemination. Expression levels of miR-26a determined by qPCR. PIF levels were assessed by using commercial ELISA kits. All data were analyzed by using the MIXED procedure of SPSS. The expression levels of miR-26a were 6.64 folds higher on D16 in pregnant compared to non-pregnant multiparous cows (p < .05). On D8 and D16, miR-26a expression levels were found higher 13 folds in pregnant compared to non-pregnant nulliparous cows (p < .05). Additionally, miR-26a expressions were higher 5.42 folds (p < .05) on D8, 7.19 folds higher (p < .01) on D16 in pregnant nulliparous and multiparous cows, and were 6.30 folds higher (p < .001) on D8 and D16 according to non-pregnant animals. PIF levels were greater in pregnant animals (p < .05). Analyzing miR-26a on D8 might be considered as sufficient in nulliparous cows. Pregnancy detection in multiparous cows can be made on the 16th day with this method. Furthermore, PIF evaluations may be sufficient on D10 in multiparous cows. Besides, PIF levels and miR-26a expression levels might be used safely in field conditions and clinical applications.

Abstract
BACKGROUND Due to limited research on the effectiveness and safety of intravenous (IV) fluids administered during labor, there are no guidelines available. Thus, this meta-analysis aims to evaluate efficacy of IV Ringer's lactate during labor as compared to usual care. METHODS Six databases were searched for the randomized controlled trials (RCTs) comparing the effects of IV Ringer's lactate at 125 mL/h or 250 mL/hr during labor in nulliparous women at term as compared to usual care, and the search results were imported to Covidence for screening of the articles. All the concerned outcomes were pooled as risk ratios (RR) or mean difference (MD) with 95% CI in the meta-analysis models using RevMan 5.4. RESULTS Pooled data from 7 RCTs with 967 nulliparous women showed that the active stage of labor duration (MD -32.16 with 95% CI [40.43 to -23.90], p < 0.00001), need of oxytocin augmentation (RR 0.72 with 95% CI [0.54 to 0.96], p = 0.03) and incidence of prolonged labor (RR 0.57 with 95% CI [0.34 to 0.95], p = 0.03) was significantly lower with IV Ringer's lactate. However, the total duration of labor (p = 0.23), duration of second stage of labor (p = 0.31) and cesarean section rate (p = 0.070) did not differ between the two groups. The test for subgroup analysis based on infusion rate was significant (p = 0.01) for the active stage of labor. CONCLUSION IV Ringer's lactate reduced the duration of active labor, the need for oxytocin augmentation and the prolonged labor incidence. However, it did not differ in effect on immediate neonatal health but was found to have more potential for reducing maternal vomiting as compared to usual care with unrestricted oral intake. Further research is needed to explore its effects in the larger and more diverse populations and with different IV fluids for evidence-based guidelines.

Abstract
BACKGROUND Unnecessary cesarean deliveries lead to increased maternal and neonatal morbidities and mortalities. In 2020, Florida had a cesarean delivery rate of 35.9%, the third highest in the nation. An effective quality improvement strategy to reduce overall cesarean delivery rates is to decrease primary cesarean deliveries in low-risk births (nulliparous, term, singleton, vertex). Of note, 3 nationally accepted hospital measures of low-risk cesarean delivery rates include the nulliparous, term, singleton, vertex; Joint Commission; and Society for Maternal-Fetal Medicine metrics. Comparing metrics is necessary because accurate and timely measurement is essential to support multihospital quality improvement efforts to reduce low-risk cesarean delivery rates and improve the quality of maternal care. OBJECTIVE This study aimed to assess differences in hospital low-risk cesarean delivery rates in Florida using 5 different metrics of low-risk cesarean delivery rate based on (1) risk methodology, nulliparous, term, singleton, vertex; Joint Commission; and Society for Maternal-Fetal Medicine metrics, and (2) data source, linked birth certificate and hospital discharge records and hospital discharge records only. STUDY DESIGN This was a population-based study of live Florida births from 2016 to 2019 to compare 5 approaches to calculating low-risk cesarean delivery rates. Analyses were performed using linked birth certificate data and inpatient hospital discharge data. The 5 low-risk cesarean delivery measures were defined as follows: nulliparous, term, singleton, vertex birth certificate; Joint Commission-linked used Joint Commission exclusions; Society for Maternal-Fetal Medicine-linked used Society for Maternal-Fetal Medicine exclusions; Joint Commission hospital discharge with Joint Commission exclusions; and Society for Maternal-Fetal Medicine hospital discharge with Society for Maternal-Fetal Medicine exclusions. Nulliparous, term, singleton, vertex birth certificate was based on data from birth certificates and not using linked hospital discharge data. Designated as nulliparous, term, singleton, vertex, it does not exclude other high-risk conditions. The second and third measures (Joint Commission-linked used Joint Commission exclusions and Society for Maternal-Fetal Medicine-linked used Society for Maternal-Fetal Medicine exclusions) use data elements from the full-linked dataset to designate nulliparous, term, singleton, vertex and excluded several high-risk conditions. The last 2 measures (Joint Commission hospital discharge with Joint Commission exclusions; and Society for Maternal-Fetal Medicine hospital discharge with Society for Maternal-Fetal Medicine exclusions) were based on data from hospital discharge data only and not using linked birth certificate data. These measures generally reflect term, singleton, and vertex because parity could not be assessed adequately on hospital discharge data. Hospital differences between these 5 measures were calculated overall and by neonatal intensive care unit level. RESULTS Overall, the median of hospital low-risk cesarean rates decreased across the measures, from NTSV-BC 30.7%, to Joint Commission linked 29.1%, and Society for Maternal Fetal Medicine hospital discharge 29.2% with a large decrease to Joint Commission hospital discharge 19.4% and Society for Maternal Fetal Medicine hospital discharge 18.1%. A similar trend was seen by neonatal intensive care unit level. For each of the measures, level II had the highest median low-risk cesarean rates (nulliparous. term, singleton, vertex birth certificate) 32.7%, Joint Commission linked (31.4%), Society for Maternal Fetal Medicine linked: 31.1%, Society for Maternal Fetal Medicine hospital discharge 19.3%), except for level III Joint Commission hospital discharge (20.0%). A comparison of the median number of low-risk births overall and by neonatal intensive care unit level showed a decreasing number across the linked and hospital discharge measures. Again, a wide gap in low-risk cesarean delivery rates was identified between linked measures and hospital discharge measures. However, this gap narrowed as hospital rates increased. CONCLUSION Quality monitoring of low-risk cesarean delivery rates measured by the nulliparous, term, singleton, vertex metric using the birth certificate was fairly accurate and provided timely assessment for use by Florida hospitals. The nulliparous, term, singleton, vertex birth certificate rates were comparable with low-risk metrics using the linked data source. Overall, metrics used within the same data source had similar rates, with the Society for Maternal-Fetal Medicine metric having the lowest rates. Across data sources, metrics using hospital discharge data only resulted in substantially underestimated rates because of the inclusion of multiparous women and should be interpreted with caution.

Abstract
Introduction The increasing Cesarean Section (CS) rates may be attributed to women's increasing requests for elective CS. High Fear of Childbirth (FOC), especially among nulliparous women, may be significantly associated with CS preference without medical indications. The current study aims to investigate the impact of childbirth fear on the mode of delivery preference among nulliparous women. Methods A cross-sectional correlational study was performed in the Maternal and Children Hospital (MCH) from the beginning of October 2022 to the end of February 2023 and incorporated a convenience sample of 342 nulliparous women. The data was collected using a self-reported questionnaire comprising participants' demographic and obstetrics characteristics and the FOC questionnaire. A logistic regression model examined the relationship between CS preference and the other independent variables. Results The results indicated that 74.3% of the nulliparous women preferred vaginal delivery, while 25.7% preferred Cesarean Section. Concerning childbirth-related fear, the highest mean scores were related to fear of clinical procedures, fear of harming or distressing the infant, and fear of pain 5.19 ± 1.13, 5.12 ± 1.27, and 5.09 ± 1.22, respectively. High FOC was present among 74.6%, moderate in 17.3%, and severe in 6.7% of the participants. Logistic regression analysis showed maternal age and monthly income were the significant sociodemographic determinants of choosing CS as the preferred delivery mode (p < 0.05). Moreover, the participants who had increased fear of harming or distressing the infant, fear from pain, fear from the body's ability to give birth, fear from not being involved in decision-making, and overall FOC had a higher probability of choosing CS as the preferred delivery mode compared to the participants who had lower fear (p < 0.05). Discussion Having high FOC increases the CS preference among nulliparous women. Increased fear of harming or distressing the infant, fear from pain, fear from the body's ability to give birth, and fear from not being involved in decision- making seem to be significant dimensions of childbirth fear associated with CS preference among nulliparous women.

Abstract
Introduction Proprioception is one's capacity to perceive bodily position, alignment, and movement. Several connective tissues, such as skin, ligaments, joint capsules, and muscles in the body, contain proprioceptive sensory receptors. Joint elasticity results from hormonal variations, notably the peak relaxin hormone during pregnancy, which also affects proprioceptive receptors. The musculoskeletal system may be affected by hormones and anatomical changes brought on by pregnancy, including joint laxity and modifications to posture and gait. The capacity to perceive the joint position and movement, or proprioception, may be impacted. To comprehend the impacts of pregnancy on joint function and postpartum women's rehabilitation options, this study compares knee joint proprioception in women who gave birth 12 weeks ago to nulliparous women. The study aims to assess and compare the degree of alteration in knee joint proprioception in 12-week postpartum females. Methodology A total of 160 participants were assessed during the entire study. Women from 18 to 35 years of age were included in the study. Women with any present knee joint injury, multiparty, or relevant surgical history were excluded. The procedure was performed under the author's surveillance at the Department of Community Health Physiotherapy. The knee joint reposition test was used to assess the knee joint proprioceptive error among two groups (80 each), including nulliparous women and the other 12-week postpartum women. An image tool provided by the University of Texas Health Science Centre at San Antonio (UTHSCSA) was created and offers the tool as computer software or a digital application for handling medical pictures and associated data, software 3.0 was used to determine the angular variation between angles in the targeted and achieved positions during the test. Result A significant proprioceptive error was observed among 12-week postpartum women compared to the nulliparous group of women. The mean error of knee joint repositions among 12-week postpartum women was 0.80±6.08 (P=0.0001), and among nulliparous women was 0.09±0.72 (P=0.0001). Conclusion Concluding insight that pregnancy affects postpartum women's risk of fall injuries and joint function due to altered proprioception. Compared to nulliparous women, proprioceptive error for the dominant knee joint was significant among 12-week postpartum females. The hormonal changes during pregnancy affect the proprioceptive receptors, especially the relaxin hormone surge, which results in joint laxity and may impair joint position sensing, increasing the risk of falls. To better acknowledge the effects of pregnancy on joint function and postpartum women's rehabilitation options, this study compares knee joint proprioception in postpartum and nulliparous women. It proves right about altered proprioception post-childbirth. The results of this study might aid medical practitioners in creating successful rehabilitation plans and treatments to stop postpartum women from falling.

Abstract
OBJECTIVE To assess the impact of low-dose aspirin (LDA) starting in early pregnancy on delaying preterm hypertensive disorders of pregnancy. DESIGN Non-prespecified secondary analysis of a randomised masked trial of LDA. SETTING The study was conducted among women in the Global Network for Women's and Children's Health's Maternal and Newborn Health Registry (MNHR) clusters, a prospective, population-based study in Kenya, Zambia, the Democratic Republic of the Congo (DRC), Pakistan, India (two sites-Belagavi and Nagpur) and Guatemala. POPULATION Nulliparous singleton pregnancies between 6+0 weeks and 13+6 weeks in six low-middle income countries (Democratic Republic of Congo, Guatemala, India, Kenya, Pakistan, Zambia) enrolled in the ASPIRIN Trial. METHODS We compared the incidence of HDP at delivery at three gestational age periods (<28, <34 and <37 weeks) between women who were randomised to aspirin or placebo. Women were included if they were randomised and had an outcome at or beyond 20 weeks (Modified Intent to Treat). MAIN OUTCOME MEASURES Our primary outcome was pregnancies with HDP associated with preterm delivery (HDP@delivery) before <28, <34 and <37 weeks. Secondary outcomes included small for gestational age (SGA) <10th percentile, <5th percentile, and perinatal mortality. RESULTS Among the 11 976 pregnancies, LDA did not significantly lower HDP@delivery <28 weeks (relative risk [RR] 0.18, 95% confidence interval [CI] 0.02-1.52); however, it did lower HDP@delivery <34 weeks (RR 0.37, 95% CI 0.17-0.81) and HDP@delivery <37 weeks (RR 0.66, 95% CI 0.49-0.90). The overall rate of HDP did not differ between the two groups (RR 1.08, 95% CI 0.94-1.25). Among those pregnancies who had HDP, SGA <10th percentile was reduced (RR 0.81, 95% CI 0.67-0.99), though SGA <5th percentile was not (RR 0.84, 95% CI 0.64-1.09). Similarly, perinatal mortality among pregnancies with HDP occurred less frequently (RR 0.55, 95% CI 0.33-0.92) in those receiving LDA. Pregnancies randomised to LDA delivered later with HDP compared with those receiving placebo (median gestational age 38.5 weeks vs. 37.9 weeks; p = 0.022). CONCLUSIONS In this secondary analysis of a study of low-risk nulliparous singleton pregnancies, early administration of LDA resulted in lower rates of preterm HDP and delivery before 34 and 37 weeks but not in the overall rate of HDP. These results suggest that LDA works in part by delaying HDP.

Abstract
BACKGROUND Preterm birth is a leading cause of perinatal morbidity and mortality. There are significant racial disparities in the rates of preterm delivery in the United States, with Black individuals at disproportionately higher risk than their White counterparts. Although low-dose aspirin is currently under investigation for reducing the rates of preterm delivery, limited data are available on how the use of low-dose aspirin might affect racial and ethnic disparities in the rates of preterm delivery. OBJECTIVE Our group and others have shown that low-dose aspirin decreases spontaneous preterm delivery in low-risk parturients. This study aimed to examine whether the relationship between low-dose aspirin and the risk of spontaneous preterm delivery is modified by race and ethnicity. STUDY DESIGN This was a secondary analysis of a randomized clinical trial examining low-dose aspirin for preeclampsia prevention in low-risk nulliparous individuals. The parent trial defined low risk as the absence of preexisting hypertension or other medical comorbidities. Participants received 60-mg aspirin or placebo between 13 and 25 weeks of gestation. Here, multiple pregnancies, fetal anomalies, terminations or abortions at <20 weeks of gestation, and participants with previous miscarriages were excluded. Our exposure, race and ethnicity, was self-reported in the parent trial and categorized as non-Hispanic White, Hispanic, non-Hispanic Black, and other. The primary outcome was spontaneous preterm delivery at <34 weeks of gestation; the secondary outcomes included spontaneous preterm delivery at <37 weeks of gestation and all preterm deliveries at <34 and <37 weeks of gestation. Fit logistic regression models were used to examine how the use of low-dose aspirin modified the relationship between race and ethnicity and preterm delivery, adjusting for confounders. Furthermore, sensitivity analyses were performed to compare the rates of preterm delivery by race and ethnicity. RESULTS Of note, 2528 of 3171 parent study participants were included in this analysis. Of the participants, 425 (16.8%) were White, 819 (32.4%) were Hispanic, 1265 (50%) were Black, and 19 (0.8%) were other. The baseline characteristics differed among racial and ethnic groups, including maternal age, body mass index, education level, marital status, tobacco and alcohol use, and pregnancy loss. The rate of spontaneous preterm delivery at <34 weeks of gestation was significantly higher in Black participants (2.8%) than in White (1.2%) and Hispanic (1.2%) participants (P=.04). Logistical regression analysis showed that Black race was no longer an independent risk factor for spontaneous preterm delivery at <34 weeks of gestation when controlling for low-dose aspirin (adjusted odds ratio, 1.71; 95% confidence interval, 0.67-4.40). A similar pattern was found for spontaneous preterm delivery at <37 weeks of gestation and preterm delivery at <34 and <37 weeks of gestation. In our sensitivity analyses, spontaneous preterm delivery at <34 weeks of gestation differed by race and ethnicity in the placebo group (P=.01) but did not differ in the low-dose aspirin group (P=.90). CONCLUSION The use of low-dose aspirin mitigated racial disparities in spontaneous preterm delivery at <34 weeks of gestation. Additional investigation is warranted to assess the reproducibility of our findings.

Abstract
Trial of labor after cesarean (TOLAC) is an alternative to repeated cesarean for women with singleton pregnancy and one previous transverse lower segment cesarean section (LSCS), resulting in most cases being a successful vaginal birth after cesarean section (VBAC). The primary objective of this study was to examine if the progress and the duration of the active first stage and the second stage of labor in nulliparous women with singleton pregnancy, spontaneous start of labor and vaginal birth differ from primiparous women succeeding VBAC after one previous elective LSCS in a country with a low cesarean section and high VBAC rate. Secondary objectives were to compare labor interventions and maternal-neonatal outcomes between the two groups. METHODS This is a retrospective comparative study. Data were collected in a four-year period at the departments of Obstetrics and Gynecology at Kristianstad and Ystad hospitals in Sweden. Out of 14,925 deliveries, 106 primipara women with one previous elective LSCS and a spontaneous labor onset in the subsequent singleton pregnancy were identified. Of these women, 94 (88.7%) delivered vaginally and were included in the study (VBAC group). The comparison group included 212 randomly selected nulliparous women that had a normal singleton pregnancy, spontaneous labor onset and delivered vaginally. RESULTS The rate of cervical dilation during the active first stage of labor as well as the duration of the second stage did not differ between the two groups. When adjusting for cervical dilation at admission, there was no significant difference between the two groups regarding the duration of the active phase of the first stage of labor. No significant differences were found in maternal-neonatal outcomes between the two groups except for higher birth weight in the VBAC group. The use of epidural analgesia was associated with slower dilation rhythm over the duration of the active phase and second stage of labor, need for labor augmentation, postpartum bleeding and need for transfusion at higher rates, irrespective of parity when epidural was used. CONCLUSIONS Our study provides evidence that in women with one previous elective LSCS undergoing TOLAC in the subsequent pregnancy resulting in vaginal birth, the progress and duration of labor are not different from those in nulliparous women when labor is spontaneous and the it is a singleton pregnancy. The use of epidural was associated with prolonged labor, need for labor augmentation and higher postpartum bleeding, irrespective of parity. This information may be useful in patient counseling and labor management in TOLAC.

Abstract
AIM To explore the association between induction of labour at full-term gestations in low-risk nulliparous women and childhood school outcomes. METHODS A retrospective whole-of-population cohort study linking perinatal data to educational test scores at grades 3, 5 and 7 in Victoria, Australia. Low-risk nulliparous women with singleton pregnancies induced at 39 and 40 weeks without a medical indication were compared to those expectantly managed from that week of gestation. Multivariable logistic regressions were used as well as generalised estimating equations on longitudinal data. RESULTS At 39 weeks, there were 3687 and 103 164 infants in the induction and expectant arms, respectively. At 40 weeks' gestation, there were 7914 and 70 280 infants, respectively. Infants born to nulliparous women induced at 39 weeks' gestation had significantly poorer educational outcomes at grade 3 (adjusted odds ratio (aOR) = 1.39, 95% confidence interval (CI): 1.13-1.70) but not grades 5 (aOR = 1.05, 95% CI: 0.84-1.33) and 7 (aOR = 1.07, 95% CI: 0.81-1.40) compared to those expectantly managed. Infants born to nulliparous women induced at 40 weeks had comparable educational outcomes at grade 3 (aOR = 1.06, 95% CI: 0.90-1.25) but poorer educational outcomes at grades 5 (aOR = 1.23, 95% CI: 1.05-1.43) and 7 (aOR = 1.23, 95% CI: 1.03-1.47) compared to those expectantly managed. CONCLUSIONS There were inconsistent associations between elective induction of labour at full-term gestations in low-risk nulliparous women and impaired childhood school outcomes.

Abstract
Background: The combination of ropivacaine and dexmedetomidine has been used as an epidural analgesic for inducing labor. However, there is limited data regarding the administration of epidural analgesia for labor maintenance, hence, this study aimed to determine the optimum concentration through dose-response curves of ropivacaine plus dexmedetomidine, which could be used along with the Programmed Intermittent Epidural Bolus (PIEB) technique. Methods: One hundred parturients were randomized into 4 groups who were administered four different doses of ropivacaine (dexmedetomidine at 0.4 μg mL-1): 0.04%, 0.06%, 0.08%, and 0.1%. The primary outcome that was determined included the proportion of patients experiencing breakthrough pain during their 1st stage of labor. Breakthrough pain was described as a visual analog scale [VAS] score of >30 mm, requiring supplemental epidural analgesia after the administration of at least one patient-controlled bolus. The effective concentration of analgesia that was used for labor maintenance in 50% (EC50) and 90% (EC90) of patients were calculated with the help of probit regression. Secondary outcomes included epidural block characteristics, side effects, neonatal outcomes, and patient satisfaction. Results: The results indicated that the proportion of patients without breakthrough pain was 45% (10/22), 55% (12/22), 67% (16/24), and 87% (20/23) for 0.04%, 0.06%, 0.08%, and 0.10% doses of the analgesic that were administered, respectively. The EC50 value was 0.051% (95% confidence interval [CI], 0.011%-0.065%) while the EC90 value was recorded to be 0.117% (95% CI, 0.094%-0.212%). Side effects were similar among groups. Conclusion: A ropivacaine dose of 0.117% can be used as epidural analgesia for maintaining the 1st stage of labor when it was combined with dexmedetomidine (0.4 μg mL-1) and the PIEB technique.

Abstract
BACKGROUND Inpatient postpartum recovery trajectories following cesarean delivery and spontaneous vaginal delivery are underexplored. OBJECTIVE This study primarily aimed to compare recovery following cesarean delivery and spontaneous vaginal delivery in the first postpartum week, and secondarily to evaluate psychometrically the Japanese version of the Obstetric Quality of Recovery-10 scoring tool. STUDY DESIGN Following institutional review board approval, the EQ-5D-3L (EuroQoL 5-Dimension 3-Level) questionnaire and a Japanese version of the Obstetric Quality of Recovery-10 measure were used to evaluate inpatient postpartum recovery in uncomplicated nulliparous parturients delivering via scheduled cesarean delivery or spontaneous vaginal delivery. RESULTS A total of 48 and 50 women who delivered via cesarean delivery and spontaneous vaginal delivery, respectively, were recruited. Women delivering via scheduled cesarean delivery experienced significantly worse quality of recovery on days 1 and 2 compared with those who had spontaneous vaginal delivery. Quality of recovery significantly improved daily, plateauing at days 4 and 3 for cesarean delivery and spontaneous vaginal delivery groups, respectively. Compared with cesarean delivery, spontaneous vaginal delivery was associated with prolonged time to analgesia requirement, decreased opioid consumption, reduced antiemetic requirement, and reduced times to liquid/solid intake, ambulation, and discharge. Obstetric Quality of Recovery-10-Japanese is a valid (correlates with the EQ-5D-3L including a global health visual analog scale, gestational age, blood loss, opioid consumption, time until first analgesic request, liquid/solid intake, ambulation, catheter removal, and discharge), reliable (Cronbach alpha=0.88; Spearman-Brown reliability estimate=0.94; and intraclass correlation coefficient=0.89), and clinically feasible (98% 24-hour response rate) measure. CONCLUSION Inpatient postpartum recovery is significantly better in the first 2 postpartum days following spontaneous vaginal delivery compared with scheduled cesarean delivery. Inpatient recovery is largely achieved within 4 and 3 days following scheduled cesarean delivery and spontaneous vaginal delivery, respectively. Obstetric Quality of Recovery-10-Japanese is a valid, reliable, and feasible measure of inpatient postpartum recovery.

Abstract
OBJECTIVE The primary aim of this study was to examine the United States Preventative Services Task Force (USPSTF) guidelines concordant low-dose aspirin (LDA) counseling and factors associated with counseling in nulliparous birthing individuals. STUDY DESIGN We conducted a retrospective cohort study of nulliparous birthing individuals who delivered between January 1, 2019 and June 30, 2020 and received prenatal care at the Duke High Risk Obstetrical Clinics (HROB). All nulliparous patients over 18 years old who established or transferred care to HROB by 16 weeks, 6 days were included in the analysis. We excluded patients with more than two previous first-trimester pregnancy losses, multiple gestation, a known contraindication to LDA, initiation of LDA prior to their prenatal care, or documented medical history of coagulation disorder. Bivariate associations between demographic/medical characteristics and our primary outcome, receipt of counseling (yes/no), were assessed using two-sample t-tests for continuous variables and chi-square or Fisher's exact test for categorical variables. Factors significantly associated with the primary outcome (p < 0.05) were entered into the multivariable logistic regression model. RESULTS Among 391 birthing individuals included in the final analysis cohort, 51.7% of eligible patients received guideline consistent LDA counseling. Factors associated with increased odds of LDA counseling were advanced maternal age (adjusted odds ratio [aOR]: 1.05, 95% confidence interval [CI]: 1.01-1.09), Black race compared with White race (aOR:1.75, 95% CI: 1.03-2.98), chronic hypertension (aOR: 4.17, 95% CI: 1.82-9.55), and obesity (aOR: 5.02, 95% CI: 3.12-8.08). CONCLUSION Approximately half of all nulliparous birthing individuals had appropriately documented LDA counseling. The USPSTF guidelines on LDA for preeclampsia risk reduction are complex, which may lead to ineffective provider adherence. Efforts to simplify guidelines and improve LDA counseling are vital to ensuring this low-cost, evidence-based preeclampsia prevention is used in a consistent and equitable manner. KEY POINTS · A total of 51.7% of eligible patients received guideline consistent LDA counseling.. · Advanced maternal age , body mass index > 30, Black race, and chronic hypertension associated with increased odds of counseling.. · Among patients most likely to be counseled, high numbers did not receive LDA counseling..

Abstract
OBJECTIVE To evaluate the safety of elective induction at or beyond 39 weeks gestation in the setting of a regional tertiary obstetric care center. METHODS We conducted a prospective cohort feasibility study of low-risk pregnant women who delivered at a regional tertiary obstetric care center. We compared maternal and neonatal outcomes of low risk pregnant women who opted for elective induction at or beyond 39 weeks gestation (n = 112) to a comparison group who opted for expectant management (n = 116). All deliveries occurred between May 1, 2019 and November 30, 2019 and February 15, 2020 and August 15, 2020. RESULTS There were no significant differences in the rates of cesarean deliveries or hypertensive disorders between women who underwent elective induction and those who chose expectant management. There were also no differences in neonatal outcomes. Women in the elective induction group received significantly more cervical ripening agents (p < 0.0001) and had significantly longer stays on the antepartum (p < 0.0001) and labor and delivery units (p = 0.0015) but experienced significantly shorter stays on the postpartum unit (p = 0.0368). There was no difference in total length of hospital stay between groups. CONCLUSION Elective induction protocols can be safely implemented in our regional tertiary obstetric care center without increased risk of maternal complications or neonatal morbidity. Women considering elective induction should be adequately counseled on use of cervical ripening agents and length of stay on antepartum and labor and delivery units.

Abstract
OBJECTIVE To compare patient-reported pain, bleeding and device safety between intrauterine contraceptive device insertion procedures employing a suction cervical stabilizer or single-tooth tenaculum. STUDY DESIGN This was a randomized, prospective, single-blinded study conducted at two centers, enrolling women aged ≥ 18 years or older, eligible for IUD insertion. Subjects were randomized to the suction cervical stabilizer or control. The primary endpoint measure was patient-reported pain, measured on a 100 mm Visual Analogue Scale (VAS). Safety was assessed on the amount of bleeding, adverse events (AEs) and serious adverse events (SAEs). Operator-assessed effectiveness and satisfaction as well as patient satisfaction with the procedure were also assessed. RESULTS One hundred women were randomized, 48 to the investigational device and 52 to control. There were no statistically significant differences between the groups in factors potentially associated with pain on IUD insertion. IUD insertion was successful in 94% of all subjects. Subjects in the investigational device group reported pain scores ≥14 points lower than in the control group at cervix grasping (14.9 vs. 31.3; p<0.001) and traction (17.0 vs. 35.9; p<0.001), and smaller differences in pain scores at the IUD insertion (31.5 vs. 44.9; p=0.021) and cervix-release (20.6 vs. 30.9; p=0.049) steps. Nulliparous women experienced the greatest pain differences to control. Mean blood loss was 0.336 (range 0.022-2.189) grams in the investigational device group and 1.336 (range 0.201-11.936) grams in the control group, respectively (p=0.03 for the comparison). One adverse event (bruising and minor bleeding) in the investigational device group was considered causally related to the study device. CONCLUSION The suction cervical stabilizer had a reassuring safety profile and its use was associated with significant reductions in pain during the IUD insertion procedure compared with standard single-tooth tenaculum use, particularly among nulliparous women.

Abstract
OBJECTIVE To assess the association between episiotomy and severe obstetric anal sphincter injury (OASIS) in nulliparous women at term according to the use of an instrument for delivery with control confounding by indication. METHODS This was an observational retrospective cohort study including 12 346 women from 2004 to 2020. All nulliparous women with a cephalic singleton pregnancy were included. The primary outcome was the occurrence of OASIS. Association between episiotomy and OASIS was assessed by multivariate logistic regression with adjustment for confounding factors and stratification on the use of an instrument at delivery. Propensity score matching was used to account for indication bias. RESULTS Among 12 346 women included, 7803 (63.2%) had an episiotomy and 4543 (36.8%) did not have an episiotomy; the rate of OASIS was similar in both groups (0.7%). After stratification on use of instrument, an association between episiotomy and OASIS was shown in the case of instrumental delivery (odds ratio [OR] 0.46, 95% confidence interval [CI] 0.26-0.80) but not if the delivery was spontaneous (OR 0.76, 95% CI 0.29-1.98). The result was similar after matching on propensity score (in the case of operative vaginal delivery: OR 0.20, 95% CI 0.10-0.75). CONCLUSION Episiotomy seems to be a protective factor for OASIS in nulliparous woman at term only in the case of operative vaginal delivery.

Abstract
BACKGROUND Assessment of labor progress via digital examination is considered the standard of care in most delivery rooms. However, this method can be stressful, painful, and imprecise, and multiple examinations increase the risk for chorioamnionitis. Intrapartum ultrasound was found to be an objective, noninvasive tool to monitor labor progression. OBJECTIVE This study aimed to investigate whether, among nulliparous women, the use of intrapartum ultrasound can reduce the rate of intrapartum fever by reducing the number of digital examinations. STUDY DESIGN This was a prospective, randomized controlled trial in term nulliparas admitted with prelabor rupture of membranes, induction of labor, or in latent phase of labor with a cervical dilation of <4 cm. Women were randomized into 1 of the following 2 arms: (1) labor progress assessed by ultrasound, avoiding digital examinations as much as possible; and (2) control group in which labor progression was assessed according to the regular protocol. Before the study, all labor ward physicians underwent training in intrapartum ultrasound. RESULTS A total of 90 women were randomized to the ultrasound group and 92 were randomized to the control group. When compared with the control group, the ultrasound group had significantly lower rates of intrapartum fever (11.1% vs 26.1%; P=.01), clinical chorioamnionitis (3.3% vs 16.5%; P>.01), and histologic chorioamnionitis (2.2% vs 9.8%; P=.03). The median number of digital examinations was significantly lower in the ultrasound group (5; interquartile range, 4-6) than in the control group (8; interquartile range, 6-10; P<.01). The median number of digital examinations per hour in the ultrasound group was significantly lower than in the control group (0.2 vs 0.4; P<.01). The induction rates, time from admission to delivery, mode of delivery, Apgar score at 5 minutes, and neonatal intensive care unit admission rates did not differ significantly between the groups. CONCLUSION The use of intrapartum ultrasound lessens the total number of digital examinations needed to be performed during labor and, consequently, the incidence of intrapartum fever and chorioamnionitis are reduced. No adverse effects on labor progression and short-term maternal or neonatal outcomes were noted.

Abstract
Urinary incontinence (UI), which affects the quality of life, is associated with different risk factors during pregnancy. We aimed to study the risk factors related to UI during pregnancy among nulliparous women in the UAE. This is a prospective descriptive survey, which included all nulliparous women after the first 24 weeks' gestation from 2012 to 2014 in a teaching hospital in the UAE. Participants were interviewed face-to-face, using a structured and pre-tested questionnaire and divided into 2 groups: those with UI and those without it. Factors which were statistically significant (P < .05) between the 2 groups were entered into an logistic regression backward logistic regression model to define the factors predicting UI. Five hundred one participants were interviewed. UI occurred in 106/501 (21.2%). The 2-sample comparison analysis showed that urinary tract infection (UTI) (47.2% vs 34.4%, P = .018) and its number of attacks (P = .007), chronic cough (28.3% vs 13.9%, P < .001) and chronic constipation (34.9% vs 19%, P < .001) were statistically significant between those who had UI and those who did not. The logistic regression backward logistic regression model showed that the risk factors which predicted UI were chronic constipation (P = .003), chronic cough (P = .008), and the number of UTI attacks (P = .036). UI affects one-fifth of nulliparous women in the UAE. Chronic cough, constipation, and repeated UTI infection, significantly increase the odds of UI during pregnancy. Addressing these risk factors may reduce the risk of UI.

Abstract
OBJECTIVE To characterize the length of the second stage of labor among women completing a first vaginal birth after a cesarean (VBAC), according to the stage of labor during primary cesarean delivery (CD). METHODS A retrospective cohort study of VBACs between 2011 and 2020. Study groups were divided as follows: CD not in labor, CD in the first stage of labor, and CD in the second stage of labor. The primary outcome was the length of the second stage. RESULTS A total of 1310 VBACs were included. The timing of the primary CD was not associated with the duration of the second stage. The median second stage of duration of VBACs with previous first stage CD versus previous CD not in labor was 81 versus 106 min, respectively (P = 0.050). In multivariable linear regression, maternal age, birth weight, and epidural were independently associated with second-stage length. Maternal and neonatal outcomes did not differ between study groups and were not affected by the second-stage length. CONCLUSION When stratified according to the labor stage of the primary CD, second-stage duration among women completing VBACs was not associated with labor stage at the primary CD. Extremes of the second-stage duration were not associated with increased morbidity.

Abstract
INTRODUCTION Severe perineal injuries at childbirth affect women's postnatal health, including future childbirths. First births with vacuum extraction carry an increased risk of obstetric anal sphincter injuries (OASIS). Lateral or mediolateral episiotomy at vacuum extraction may decrease the risk of OASIS. Our aim was to assess whether lateral or mediolateral episiotomy, or OASIS, at vacuum extraction in nulliparous women is associated with prelabor cesarean delivery in the subsequent childbirth. MATERIAL AND METHODS This is a nationwide observational study using data from the Swedish Medical Birth Register, including women having a first birth with vacuum extraction and a second birth in 2000-2014. Both births were live, single, cephalic, ≥34 gestational weeks without malformations. The association between episiotomy or OASIS in the first birth and prelabor cesarean delivery in the second birth was examined using univariate and multivariate logistic regression with inverse probability of treatment weighting, and interaction analysis. Main outcome measure was prelabor cesarean delivery in the second birth. RESULTS In total, 44 656 women with vacuum extraction at their first birth were included. The rate of prelabor cesarean delivery in the second birth was 5.9% (824 of 13 950) in women with episiotomy, compared with 6.0% (1830 of 30 706) in women without episiotomy. Thus, women with episiotomy did not have an increased risk of prelabor cesarean delivery (adjusted odds ratio [aOR] 1.00, 95% confidence interval [95% CI] 0.83-1.20) compared with women without episiotomy. For comparison, the rate of prelabor cesarean delivery in the second birth was 20.6% (1275 of 6176) in women with OASIS, compared with 3.6% (1379 of 38 480) in women without OASIS (aOR 6.57, 95% CI 5.97-7.23). There was no interaction between episiotomy and OASIS. CONCLUSIONS Lateral or mediolateral episiotomy at vacuum extraction in nulliparous women did not increase the risk of prelabor cesarean delivery in the subsequent childbirth. OASIS increased the odds of prelabor cesarean delivery more than sixfold.

Abstract
AIM To determine if the time to cervical change and time to active labor were different when misoprostol was administered by a vaginal or buccal route for cervical ripening in nulliparas undergoing labor induction at term. METHODS This was a secondary analysis of nulliparous participants in the IMPROVE Study-A comparison of vaginal versus buccal misoprostol for cervical ripening for labor induction at term: a triple-masked randomized controlled trial (NCT02408315). The parent study was a non-inferiority randomized controlled trial in which patients beginning induction with a modified Bishop score ≤6 received either vaginal or buccal misoprostol and simultaneous placebo via the opposite route. The primary outcome of the parent study was time to delivery. Primary outcomes for this secondary analysis were the time to active labor (at least 6 cm dilated) and time to change in cervical dilation. Kaplan-Meier analysis was used to compare routes for time to active labor and multistate Markov modeling was used to compare sojourn times at each cervical dilation. RESULTS Of the 300 participants enrolled in the parent trial, 124 (41.3%) were nulliparous; 59 (47.6%) nulliparous participants underwent induction with vaginal misoprostol and 65 (52.4%) received buccal dosing. Nulliparas receiving vaginal dosing required fewer doses of misoprostol to reach active labor (median 2 vs 3, p = .003). However, this did not result in shorter time to active labor (median vaginal 23.1 h, 95% CI = [21.6, 27.2 h]; buccal 25.6 h [21.5, 29.3 h], p = .45) or higher rate of vaginal delivery within 24 h; (33.9% vs 35.4%, p = .86). There was also no significant difference in time to active labor after adjusting for covariates (adjusted HR for dose route (buccal vs vaginal) = 0.91 [0.61, 1.36], p = .649). Among people that delivered vaginally, the mean sojourn times, measuring cervical dilation state change, were not significantly different, with mean duration to active labor of 20.5 [17.6, 24.5] h for buccal and 21.8 [17.7, 28.2] h for vaginal dosing (p = .092). Satisfaction and preference for dosing routes were not different between groups. CONCLUSION Buccal and vaginal dosing of misoprostol for cervical ripening in nulliparas appear to have similar times to active labor and progression of cervical change during ripening.

Abstract
OBJECTIVES To evaluate the rate of subsequent spontaneous preterm birth in patients with previous induction of labour at term compared to women with previous spontaneous labour at term. METHODS This was a retrospective cohort study of all women with consecutive births at the Royal Brisbane and Women's Hospital between 2014 and 2018. All nulliparous women with a singleton pregnancy and induction of labour at term or in spontaneous labour at term in the index pregnancy were included. Data was extracted from electronic medical records. The outcome of spontaneous preterm birth in the subsequent pregnancy was compared between patients with previous term induction of labour and in previous term spontaneous labour. RESULTS A total of 907 patients with consecutive births met the inclusion criteria; of which 269 (29.7%) had a term induction of labour and 638 (70.3%) had a term spontaneous labour in the index pregnancy. The overall subsequent spontaneous preterm birth rate was 2.3%. Nulliparous women who underwent term induction of labour were less likely to have a subsequent preterm birth compared to nulliparous women in term spontaneous labour (0.74 vs. 2.98%; odds ratio [OR], 0.25; 95% confidence interval, 0.06-1.07; p=0.0496) in the index pregnancy. This however was not significant once adjusted for confounders (adjusted OR, 0.29; p=0.10). Spontaneous preterm birth was associated with a previous spontaneous labour compared to induction of labour between 37 to 37+6 and 38 to 38+6 weeks (adjusted OR 0.18 and 0.21; p=0.02 and 0.004 respectively). CONCLUSIONS Term induction of labour does not increase the risk of subsequent spontaneous preterm birth compared to spontaneous labour at term in nulliparous women. Further research is needed to validate these findings in a larger cohort of women and to evaluate the effect of elective IOL among low-risk nulliparous women.

Abstract
Background The female breast is a symbol of femininity and aesthetics having a great psychosocial impact on the woman's sense of wellbeing and self-esteem. To optimize satisfaction of patients in cosmetic and reconstructive breast surgeries, there is a need to define the dominant breast size and shape that connotes feminine attractiveness. This necessitates the knowledge of ideal data for normal nulliparous female breast parameters and volume for various body sizes in the particular population, nationality, and race. Aim To establish reference data for normal breast parameters and volumes for the various body sizes amongst the Nigerian population and to determine their relationships with other body parameters. Patients and Methods A total of 528 breasts from 264 Nigerian undergraduate post-menarcheal nulliparous students of the University of Nigeria Enugu Campus aged between 17 and 29 years were measured. Thirty-one (31) anthropomorphic parameters and five body size anthropometric indicators were measured. Data obtained were analyzed using Statistical Package for Social Sciences (SPSS) version 21(IBM) and were summarized using various descriptive statistics tools. Results The mean nipple-nipple distance is 23.37 ± 3.10. The mean left Midclavicle-nipple Length (22.17 ± 3.5 cm) is significantly (P = 0.04) higher than the right (21.79 ± 3.3 cm) just as the mean left (12.60 ± 2.5) medial radius is significantly (P = 0.0001) longer than the right (12.45 ± 2.4 cm). The mean left nipple projection (0.37 ±0.2 cm) and left vertical surface dimension (32.27 ± 5.7 cm) are significantly (P > 0.05) longer than the right (0.33 ±0.2) and (31.76 ± 5.2 cm). Also the mean volume for the left breast (605.26 ± 280.52 cm) is significantly (0.0001) higher than that of the right breast (592.53 ± 278.69). Breast volume correlated well with most of the breast parameters, BMI, and other anthropometric variables. Most breasts were ptotic (51%, 55%), especially the left breasts. Breast dimensions were asymmetrical in >50% of subjects, where the left breasts were seen to have slightly greater breast dimensions than right. Conclusion Breast values and related body size parameters were noted to be comparatively higher than earlier reported values mostly for the Asian population.

Abstract
BACKGROUND Immunomodulation is observed in human parturition. However, data from longitudinal studies for the prelabor phase and the active phase of labor are lacking, and no study had compared the immune responses during labor between nulliparous and multiparous women. OBJECTIVE This study aimed to investigate the temporal changes of immune biomarkers in maternal blood from the prelabor phase to the latent and active phases of labor and to compare the dynamic changes between nulliparous and multiparous women. STUDY DESIGN A prospective case-control study was conducted on women who had induction of labor at term followed by vaginal delivery. Maternal blood was serially collected at 3 consecutive time points: (1) before the onset of labor, (2) during the latent phase of labor, and (3) during the active phase of labor. Peripheral immune cells were measured by 4-color flow cytometry, and the plasma concentrations of cytokines and chemokines were measured by cytometric bead arrays. A longitudinal comparison was made to assess the dynamic changes in inflammatory parameters over 3 time points in nulliparous and multiparous women, respectively, and a cross-sectional comparison was made between nulliparous and multiparous women. RESULTS A total of 40 women, including 20 nulliparous and 20 multiparous, were included in the study. Prelabor circulating levels of macrophage inflammatory protein-1β, monokine induced by gamma interferon, and interferon gamma-induced protein-10 were higher in multiparous women than in nulliparous women. In the latent phase of labor, the innate immune system in both groups responded with increases in neutrophils and interleukin 6, and the nulliparous women showed a more pronounced response. During the active phase of labor, such innate immune response continued with both groups, with additional increases in natural killer cells, monocyte chemoattractant protein-1, interleukin 8, and interleukin 10. Conversely, the adaptive immune system in nulliparous women showed a reduction in both cytotoxic and helper T cells, whereas the adaptive immune system in multiparous women only had a reduction in helper T cells, showing a smaller reduction. CONCLUSION Innate and adaptive immune responses partake in immunomodulation during human parturition. Nulliparous and multiparous women showed different responses in their blood levels of immune cells and biomarkers during the different phases of labor.

Abstract
BACKGROUND The ARRIVE trial demonstrated the benefit of induction of labor at 39 weeks gestation. Obstetrics departments across the United States faced the challenge of adapting clinical practice in light of these data while managing logistical constraints. OBJECTIVE To determine if there were changes in obstetrical practices and perinatal outcomes in the United States after the ARRIVE trial publication. STUDY DESIGN This was a population-based retrospective cohort study of low-risk, nulliparous women who initiated prenatal care by 12 weeks gestation with singleton, nonanomalous pregnancies delivering at ≥39 weeks. Data were obtained from the US Natality database. The pre-ARRIVE group were women who delivered between January 1, 2015 and December 31, 2017. The post-ARRIVE group consisted of women who delivered between January 1, 2019 and December 31, 2019. Births that occurred in 2018 were excluded. Practice outcomes were rates of induction of labor, timing of delivery, and cesarean delivery rate. Adverse maternal outcomes were blood transfusion and admission to medical intensive care unit. Adverse neonatal outcomes were need for assisted ventilation (immediate and >6 hours), 5-minute APGAR score <3, neonatal intensive care unit admission, seizures, and surfactant use. Univariate and multivariate analyses were performed. Trends were tested across the time period represented by the pre-ARRIVE group using Cochran-Armitage trend test. RESULTS There were 1,966,870 births in the pre-ARRIVE group and 609,322 in the post-ARRIVE group. The groups differed in age, race, body mass index, marital status, infertility treatment, and smoking history (P<.001). After adjusting for these differences, the post-ARRIVE group was more likely to undergo induction (36.1% vs 30.2%; adjusted odds ratio, 1.36 [1.36-1.37]) and deliver by 39+6 weeks of pregnancy (42.8% vs 39.9%; adjusted odds ratio, 1.14 [1.14-1.15]). The post-ARRIVE group had a significantly lower rate of cesarean delivery than the pre-ARRIVE group (27.3 % vs 27.9%; adjusted odds ratio, 0.94 [0.93-0.94]). Patients in the post-ARRIVE group were more likely to receive a blood transfusion (0.4% vs 0.3%; adjusted odds ratio, 1.43 [1.36-1.50]) and be admitted to medical intensive care unit (0.09% vs 0.08%; adjusted odds ratio, 1.20 [1.09-1.33]). Neonates in the post-ARRIVE group were more likely to need assisted ventilation at birth (3.5% vs 2.8%; adjusted odds ratio, 1.28 [1.26-1.30]) and >6 hours (0.6% vs 0.5%; adjusted odds ratio, 1.36 [1.31-1.41]). The neonates in the post-ARRIVE group were more likely to have low 5-minute APGAR scores (0.4% vs 0.3%; adjusted odds ratio, 0.91 [0.86-0.95]). Neonatal intensive care unit admission did not differ between the 2 groups (4.9% vs 4.9%; adjusted odds ratio, 1.01 [0.99-1.03]). There were no differences in neonatal seizures (0.04% vs 0.04%; adjusted odds ratio, 0.97 [0.84-1.13]), and surfactant use (0.08% vs 0.07%; adjusted odds ratio, 1.05 [0.94-1.17]) between the 2 groups. CONCLUSION There were more inductions of labor, more deliveries at 39 weeks' gestation, and fewer cesarean deliveries in the year after the ARRIVE trial publication. The small but statistically significant increase in some adverse maternal and neonatal outcomes should be explored to determine if they are related with concurrent changes in obstetrical practices.

Abstract
BACKGROUND Cesarean delivery rates have been used as obstetrical quality indicators. However, these approaches do not consider the accompanying maternal and neonatal morbidities. A challenge in the field of obstetrics has been to establish a valid outcomes quality measure that encompasses preexisting high-risk maternal factors and associated maternal and neonatal morbidities and is universally acceptable to all stakeholders, including patients, healthcare providers, payers, and governmental agencies. OBJECTIVE This study aimed to (1) establish a new single metric for obstetrical quality improvement among nulliparous patients with term singleton vertex-presenting fetus, integrating cesarean delivery rates adjusted for preexisting high-risk maternal factors with associated maternal and neonatal morbidities, and (2) determine whether obstetrician quality ranking by this new metric is different compared with the rating based on individual crude and/or risk-adjusted cesarean delivery rates. The single metric has been termed obstetrical safety and quality index. STUDY DESIGN This was a cross-sectional study of all nulliparous patients with term singleton vertex-presenting fetuses delivered by 12 randomly chosen obstetricians in a single institution. A review of all records was performed, including a review of maternal high-risk factors and maternal and neonatal outcomes. Maternal and neonatal medical records were reviewed to determine crude and adjusted cesarean delivery rates by obstetricians and quantify maternal and neonatal complications. We estimated the obstetrician-specific crude cesarean delivery rates and rates adjusted for obstetrician-specific maternal and neonatal complications from logistic regression models. From this model, we derived the obstetrical safety and quality index for each obstetrician. The final ranking based on the obstetrical safety and quality index was compared with the initial ranking by crude cesarean delivery rates. Maternal and neonatal morbidities were analyzed as ≥1 and ≥2 maternal and/or neonatal complications. RESULTS These 12 obstetricians delivered a total of 535 women; thus, 1070 (535 maternal and 535 neonatal) medical records were reviewed to determine crude and adjusted cesarean delivery rates by obstetricians and quantify maternal and neonatal complications. The ranking of crude cesarean delivery rates was not correlated (rho=0.05; 95% confidence interval, -0.54 to 0.60) to the final ranking based on the obstetrical safety and quality index. Of note, 8 of 12 obstetricians shifted their rank quartiles after adjustments for high-risk maternal conditions and maternal and neonatal outcomes. There was a strong correlation between the ranking based on ≥1 maternal and/or neonatal complication and ranking based on ≥2 maternal and/or neonatal complications (rho=0.63; 95% confidence interval, 0.08-0.88). CONCLUSION Ranking based on crude cesarean delivery rates varied significantly after considering high-risk maternal conditions and associated maternal and neonatal outcomes. Therefore, the obstetrical safety and quality index, a single metric, was developed to identify ways to improve clinician practice standards within an institution. Use of this novel quality measure may help to change initiatives geared toward patient safety, balancing cesarean delivery rates with optimal maternal and neonatal outcomes. This metric could be used to compare obstetrical quality not only among individual obstetricians but also among hospitals that practice obstetrics.

Abstract
Maternal race, ethnicity and socio-economic position are known to be associated with increased risk for a range of poor pregnancy outcomes, including maternal morbidity and mortality. Previously, researchers seeking to identify the contributing factors focused on maternal behaviors and pregnancy complications. Less understood is the contribution of the social determinants of health (SDoH) in observed differences by race/ethnicity in these key outcomes. In this secondary analysis of the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be (nuMoM2b) dataset, latent mixture modeling was used to construct groups of healthy, nulliparous participants with a non-anomalous fetus in a cephalic presentation having a trial of labor (N = 5763) based on SDoH variables. The primary outcome was a composite score of postpartum maternal morbidity. A postpartum maternal morbidity event was experienced by 350 individuals (6.1%). Latent class analysis using SDoH variables revealed six groups of participants, with postpartum maternal morbidity rates ranging from 8.7% to 4.5% across groups (p < 0.001). Two SDoH groups had the highest odds for maternal morbidity. These higher-risk groups were comprised of participants with the lowest income and highest stress and those who had lived in the USA for the shortest periods of time. SDoH phenotype predicted MM outcomes and identified two important, yet distinct groups of pregnant people who were the most likely have a maternal morbidity event.

Abstract
Background: The aim of this study is to demonstrate that a double balloon catheter combined with oxytocin decreases time between induction of labor and delivery (TID) as compared to a vaginal dinoprostone insert in cases of premature rupture of membranes at term. Methods: This is a prospective, randomized, controlled trial including patient undergoing labor induction for PROM at term with an unfavorable cervix in Clermont-Ferrand university hospital. We compared the double balloon catheter over a period of 12 h with adjunction of oxytocin 6 h after catheter insertion versus dinoprostone vaginal insert. After device ablation, cervical ripening continued only with oxytocin. The main outcome was TID. Secondary outcomes concerned delivery mode, as well as maternal and fetal outcome, and were adjusted for parity. Results: 40 patients per group were randomized. Each group had similar baseline characteristics. The study failed to demonstrate reduced TID (16.2 versus 20.2 h, ES = 0.16 (−0.27 to 0.60), p = 0.12) in the catheter group versus dinoprostone except in nulliparous women (17.0 versus 26.5 h, ES = 0.62 (0.10 to 1.14), p = 0.006). The rate of vaginal delivery <24 h significantly increased with combined induction (88.5% versus 66.6%, p = 0.03). No statistical difference was observed concerning caesarean rate (12.5% versus 17.5%, p > 0.05), chorioamnionitis (0% versus 2.5%, p = 1), postpartum endometritis, or maternal or neonatal outcomes. Procedure-related pain and tolerance to devices were found to be similar for the two methods. Interpretation: The double balloon catheter combined with oxytocin is an alternative for cervical ripening in case of PROM at term, and may reduce TID in nulliparous women.

Abstract
In this study, it was aimed to evaluate the reproductive performance of primiparous and nulliparous Saanen goats following the insemination made cervically via frozen commercial buck semen with short-time controlled internal drug release (CIDR, Eazi-Breed, Pfizer)-based synchronization. In the study, a total of 50 Saanen goats, 26 of which were aged 9 months and 24 of which were aged 2 years, were used. The CIDRs including 0.33 g of progesterone were applied to all the goats for 7 days and while the CIDRs were taken out of the vagina, the 500 IU equine chorionic gonadotropin (eCG) was injected intramuscularly. The first dose was administered in a fixed-time manner with mini straws of 0.25 ml including 300x106 motile frozen spermatozoa 24 hours after the injection without making estrus detection, and the second dose insemination was applied 24 hours later. In the study, although the pregnancy rate, fecundity, prolificacy and multiple birth rate values (83%, 1.25, 1.50 and 60%) obtained in the primiparous goats were found to be higher than those found in the nulliparous age group (80%, 0.84, 1.05 and 38%), they were not statistically significant. It was concluded that the effects of the CIDR-based double-dose insemination applications in the primiparous and nulliparous Saanen breed goats in breeding season for 7 days on fertility were similar and the cervical insemination method, a quick and more practical option compared to the intrauterine insemination, could be used successfully in both age groups.

Abstract
Simple Summary Parity and season are two prominent variants which influence buffalo reproductive performance and synchronization outcome. The present study compared modified new Ovsynch synchronization (GPGMH) protocol with conventional Ovsynch (OVS) in reproductive parameters of buffaloes with different parity (nulliparous and multiparous) in different seasons (peak and low breeding seasons). Compared to the conventional Ovsynch, the modified GPGMH protocol was more effective to enhance the estrus rate, ovulation rate and pregnancy rate in multiparous crossbred buffaloes. In addition, the application of GPGMH protocol improve the reproductive performance during the peak breeding season than low breeding season. Abstract The present study was conducted to examine the effect of conventional the Ovsynch protocol (OVS) and a modified Ovsynch synchronization (GPGMH) protocol on the follicular dynamics, estrus, ovulation, and pregnancy in nulliparous and multiparous crossbred (swamp × riverine) buffaloes during different seasons. GPGMH or OVS protocols were used to synchronize nulliparous (n = 128; GPGMH = 94, OVS = 34) and multiparous (n = 154; GPGMH = 122, OVS = 32) buffaloes during the peak (n = 186; GPGMH = 143, OVS = 43) and low breeding (n = 96; GPGMH = 73, OVS = 23) seasons. Buffaloes were monitored for follicular dynamics, estrus response, ovulation, and pregnancy rates. The results showed that protocol, parity, and season had significant effects on estrus, ovulation, and pregnancy variables, and interactions among parity and protocol, season and protocol, and season and parity were observed for few of reproductive indices in the crossbred buffaloes. There were no significant (p > 0.05) interaction for protocol, parity and season. In multiparous buffaloes, the application of the GPGMH protocol significantly (p < 0.05) increased the interaction to the interval to estrus onset after the second GnRH, estrus response, ovulation rate, and pregnancy rate, and lowered (p < 0.05) the silent estrus when compared with the conventional OVS protocol. During the peak breeding season, the application of the GPGMH protocol significantly (p < 0.05) improved the interaction to the estrus response, ovulation rate, and pregnancy rate, while it lowered (p < 0.05) the silent estrus incidence when compared to the conventional OVS protocol. In conclusion, the GPGMH protocol, in comparison to the OVS protocol, improves the follicular dynamics, estrus response, ovulation, and pregnancy rates in crossbred multiparous buffaloes during the peak breeding seasons.

Abstract
AIM Age at menarche is used as a risk indicator of gestational diabetes mellitus, preterm birth, and fetal growth. However, little is known regarding the age impact on obstetric outcomes among nulliparous women. This study investigated whether menarche age was correlated with obstetric outcomes among nulliparous women. METHODS We analyzed the data obtained for 37 645 singleton pregnancies between 2011 and 2014 in the Japan Environment and Children's Study. Age at menarche was categorized into the ≤9-, 10-, 11-, 12-, 13-, 14-, and ≥15-year-old groups (n = 363, 3155, 8390, 11 164, 6713, 5446, and 2414, respectively). We calculated the relative risk for cases of preterm birth <37 weeks, low birthweight <2500 g, small for gestational age, early and late-onset hypertension disorders of pregnancy, and early- and late-diagnosed (diagnosed < or ≧ 24 weeks) gestational diabetes mellitus using a reference of 12 years at menarche. RESULTS Women with an age at menarche ≤9 years showed an increased incidence of developing early-diagnosed gestational diabetes mellitus (relative risk: 2.42; 95% confidence interval: 1.05-5.60). A high body mass index before pregnancy increased the risk of developing gestational diabetes mellitus. CONCLUSIONS Age at menarche helped in assessing the risk of early-diagnosed gestational diabetes mellitus among nulliparous women. Future studies are needed to clarify the underlying mechanisms. This study is the first to use data from the largest prospective birth cohort study of Japan and to investigate the relationship between menarche age and obstetric outcomes among nulliparous women.

Abstract
Urinary incontinence (UI) is described as unintentional voiding of urine that is usually seen in post-partum and post-menopausal women due to the weakening of pelvic floor muscles (PFM). Recent studies have shown an increase in the prevalence of stress urinary incontinence (SUI) among young nulliparous female athletes. The association between UI and high-impact physical activity is due to increased intra-abdominal pressure during high-impact sports exceeding intra-urethral pressure. Usually, the levator ani muscle (LAM) helps in urethral closure. However, weakening or injury of LAM can reduce the pelvic support and cause UI in young female athletes. This study aims to assess the prevalence of SUI among young nulliparous athletes and also explore the association between SUI and athletic sports in young females. We searched PubMed and Google Scholar as databases to find specific articles about the topic. After the inclusion and exclusion criteria were applied, 52 articles were selected for this review. It is found that there is an increased UI prevalence, mainly SUI, among young nulliparous female athletes, especially in volleyball players and long-distance runners. Nulliparous athletes involved in high-impact exercises were found to have an increased cross-sectional area of LAM and puborectalis muscle width. SUI is usually under-reported and underdiagnosed due to lack of knowledge and unawareness, which can negatively affect the personal and social life of young females. PFM training is considered the first line of therapy among nulliparous athletes. However, it is unclear whether the high-impact effects of sports cause UI through PFM fatigue or PFM damage. More research is needed to better understand this effect.

Abstract
Objective This study aimed to identify factors associated with meeting the Obstetric Care Consensus (OCC) guidelines for nulliparous, term, singleton, and vertex (NTSV) cesarean births. Materials and methods This was a retrospective case control study of women with NTSV cesarean births between January 2014 and December 2017 at single tertiary care center. Demographics and clinical characteristics were compared between women with NTSV cesarean births which did or did not meet OCC guidelines. A multivariable logistic regression model was used to evaluate the effect of each variable on the odds of meeting OCC guidelines. Results There were 1,834 women with NTSV cesarean births of which 744 (40.6%) met OCC guidelines for delivery and 1,090 (59.4%) did not. After controlling for confounding factors, the odds of meeting OCC guidelines were increased for in-house providers managing with residents (adjusted odds ratio [aOR] = 2.03, 95% confidence interval [CI]: 1.44-2.87) and without residents (aOR = 1.66, 95% CI: 1.30-2.12), compared with non-in-house providers managing without residents. There was no significant difference in the odds of meeting OCC guidelines for in-house providers managing with or without residents (aOR = 1.23, 95% CI: 0.84-1.79). Conclusion After adjusting for confounding factors, in-house provider coverage, regardless of resident involvement, is associated with increased odds of NTSV cesarean births meeting OCC guidelines. Key Points Frequency of adherence to OCC guidelines for NTSV cesarean births was 40.6%.Neither patient demographics nor comorbidities was associated with the odds of meeting OCC guidelines.In-house providers are associated with increased odds of meeting OCC guidelines.

Abstract
OBJECTIVE This study aimed to evaluate maternal and neonatal outcomes by method of cervical ripening for labor induction among low-risk nulliparous individuals. STUDY DESIGN This is a secondary analysis of a multicenter randomized trial of labor induction at 39 weeks versus expectant management in low-risk nulliparous participants. Participants undergoing cervical ripening for labor induction in either group were included. Participants were excluded for preripening membrane rupture, abruption, chorioamnionitis, fetal demise, or cervical dilation ≥3.5 cm. Cervical ripening was defined by the initial method used: prostaglandin only (PGE; referent), Foley with concurrent prostaglandin (Foley-PGE), Foley only (Foley), and Foley with concurrent oxytocin (Foley-oxytocin). Coprimary outcomes were adverse maternal and neonatal composites. Secondary outcomes included cesarean delivery and length of labor and delivery (L&D) stay. Multivariable analysis was used to adjust for patient characteristics. RESULTS Of 6,106 participants included in the trial, 2,376 (38.9%) met criteria for this analysis. Of these, 1,247 (52.4%) had cervical ripening with PGE, 290 (12.2%) had Foley-PGE, 385 (16.2%) had Foley, and 454 (19.1%) had Foley-oxytocin. The maternal composite outcome was similar among participants who received Foley-PGE (24.1%, adjusted relative risk [aRR] = 1.21, 95% confidence interval [CI]: 0.96-1.52), Foley (21.3%, aRR = 1.16, 95% CI: 0.92-1.45), or Foley-oxytocin (19.4%, aRR = 1.04, 95% CI: 0.83-1.29), compared with PGE (19.7%). The neonatal composite outcome was less frequent in participants who received the Foley-PGE (2.4%, aRR = 0.35, 95% CI: 0.16-0.75) or Foley (3.6%, aRR = 0.51, 95% CI: 0.29-0.89) but did not reach statistical significance for participants who received Foley-oxytocin (4.6%, aRR = 0.63, 95% CI: 0.40-1.01) compared with PGE only (6.8%). Participants who received Foley-PGE or Foley-oxytocin had a shorter L&D stay (adjusted mean difference = -1.97 hours, 95% CI: -3.45 to -0.49 and -5.92 hours, 95% CI: -7.07 to -4.77, respectively), compared with PGE. CONCLUSION In term low-risk nulliparous participants, Foley alone or concurrent with PGE is associated with a lower risk of adverse neonatal outcomes than with PGE alone. Length of L&D stay was the shortest with concurrent Foley-oxytocin. KEY POINTS · Adverse maternal outcomes are similar among different methods of cervical ripening in low-risk women.. · Adverse neonatal outcomes are less frequent with use of Foley alone or in combination with PGE.. · The use of Foley alone, or in combination with other agents, appears to be beneficial..

Abstract
OBJECTIVE The aim of the study is to evaluate the association between amniotomy at various time points during labor induction and maternal and neonatal outcomes among term, nulliparous women. STUDY DESIGN Secondary analysis of a randomized trial of term labor induction versus expectant management in low-risk, nulliparous women (2014-2017) was conducted. Women met inclusion criteria if they underwent induction ≥38 weeks' gestation using oxytocin with documented time and type of membrane rupture. Women with antepartum stillbirth or fetal anomaly were excluded. The primary outcome was cesarean delivery. Secondary outcomes included maternal and neonatal complications. Maternal and neonatal outcomes were compared among women with amniotomy versus women with intact membranes and no amniotomy at six 2-hour time intervals: before oxytocin initiation, 0 to <2 hours after oxytocin, 2 to <4 hours after, 4 to <6 hours after, 6 to <8 hours after, and 8 to <10 hours after. Multivariable logistic regression adjusted for maternal age, body mass index, race/ethnicity, modified Bishop score on admission, treatment group, and hospital (as a random effect). RESULTS Of 6,106 women in the parent trial, 2,854 (46.7%) women met inclusion criteria. Of these 2,340 (82.0%) underwent amniotomy, and majority of the women had amniotomy performed between 2 and <6 hours after oxytocin. Cesarean delivery was less frequent among women with amniotomy 6 to <8 hours after oxytocin compared with women without amniotomy (21.9 vs. 29.7%; adjusted odds ratio 0.61, 95% confidence interval 0.42-0.89). Amniotomy at time intervals ≥4 hours after oxytocin was associated with lower odds of labor duration >24 hours. Amniotomy at time intervals ≥2 hours and <8 hours after oxytocin was associated with lower odds of maternal hospitalization >3 days. Amniotomy was not associated with postpartum or neonatal complications. CONCLUSION Among a contemporary cohort of nulliparous women undergoing term labor induction, amniotomy was associated with either lower or similar odds of cesarean delivery and other adverse outcomes, compared with no amniotomy.

Abstract
OBJECTIVE In 2014, the American College of Obstetricians and Gynecologists (ACOG) and the Society for Maternal Fetal Medicine (SMFM) published an Obstetric Care Consensus for safe prevention of primary cesarean delivery. We aimed to assess whether these guidelines decreased the primary CD rate during the second stage of labor, in our department. DESIGN, SETTING, AND POPULATION A retrospective cohort study of all women reaching the second stage of labor, at term, in a single university-affiliated medical center between2010 and 2017. METHODS We compared maternal and neonatal outcomes over three year's periods:-pre-guidelines (2010-2013) vs. 2nd period - post-guidelines (2014-2017). THE MAIN OUTCOME MEASURES CD rate at 2ndstage of labor. RESULTS The study included 11,464 women. The CD rate in the 2nd stage of labor has increased significantly from 4% to 5.9% in the post-guidelines period (OR 1.48, 95% CI 1.16-1.89, p = .001). After a sub-analysis of specific subgroups, and adjustment for confounders, the increase was solely observed in nulliparous women (aOR 1.418, 95% CI 1.067-1.885, p = .016). Furthermore, increased odds for vaginal operative delivery were observed in the multiparous women in the post-guidelines period (2.7% vs. 4.1%, p = .046). CONCLUSIONS The implementation of the new ACOG and SMFM guidelines was not associated with a change in the CD rate performed at the 2nd stage of labor in the whole study population. However, there was a rise in the CD rate performed at the 2nd stage in nulliparous women. Furthermore, there was an increase in operative deliveries in the whole study population, especially in multiparous women, without an apparent increase in other immediate adverse neonatal or maternal outcomes.

Abstract
A review of the literature was performed to explore the association between prenatal education and rates of primary cesarean birth for women at low risk for cesarean birth. Most women who are nulliparous with a singleton fetus of term gestational age and in the vertex position are considered to be at low risk and favorable for a vaginal birth, yet the cesarean birth rate for women at low risk was 25.6% in 2019. It has been suggested that the rise in the cesarean birth rate among low-risk women may not be due to medical indications but, rather, to nonmedical factors, such as a provider's or woman's preference or lack of prenatal education. Evidence from this literature review supports the premise that prenatal education classes should be routinely incorporated into maternity care in an effort to reduce cesarean birth rates for the low-risk population.

Abstract
OBJECTIVE To establish the prevalence and risk factors of urinary and anal incontinence in nulliparous women. STUDY DESIGN Thirty-one catholic convents were sent a validated questionnaire to determine the prevalence and severity of urinary incontinence, and a similarly structured questionnaire to assess anal incontinence. Multivariable regression models were used to determine independent risk factors associated with the likelihood of urinary incontinence or anal incontinence. MAIN OUTCOME MEASURES Urine/faecal/flatal incontinence and symptom severity. RESULTS Of 202 nuns, 167 (83%) returned the questionnaire. Twenty-two women were excluded due to history of childbirth. Of 145 nulliparous women, 56.2% reported urinary incontinence and 53.8% reported anal incontinence. Women aged 66-76 years had significantly increased odds of experiencing urinary incontinence in comparison to women aged 40-65 years: OR: 2.35 (95% CI: 1.02-5.45) (p = 0.04). The risk of urinary incontinence was increased in women with a body mass index ≥ 30 in comparison to those with a body mass index < 19: OR: 6.25 (95% CI: 1.03-38.08) (p = 0.04). With regards to anal incontinence, although none of the differences with age and body mass index groups reached statistical significance, there was a trend towards women in higher body mass index groups having an increased prevalence of anal incontinence. Current/previous hormonal replacement therapy was also associated with significantly increased odds of experiencing urinary incontinence: OR: 2.53 (95% CI: 1.01-6.36), (p = 0.04). However, when adjusting for age and body mass index, there was no significant association with urinary incontinence. CONCLUSIONS This study highlights that while childbirth is an important risk factor, urinary incontinence and anal incontinence also occur in over 50% of nulliparous women. Additional studies are required to identify other risk factors that may be associated with incontinence in this population.

Abstract
OBJECTIVES This study aimed to investigate the role of prolonged second stage of labour and second stage caesarean section on the risk of spontaneous preterm birth (sPTB) in a subsequent pregnancy. METHODS This was a retrospective cohort study of nulliparous women with two consecutive singleton deliveries between 2014 and 2017 at a tertiary centre. In the vaginal delivery cohort, subsequent pregnancy outcomes for women with a prolonged second stage (>2 h) were compared with those with a normal second stage (≤2 h). In the caesarean delivery cohort, women with a first stage or a second stage were compared with the vaginal delivery cohort. The primary outcome was subsequent sPTB. RESULTS A total of 821 women met inclusion criteria, of which 74.8% (614/821) delivered vaginally and 25.2% (207/821) delivered by caesarean section. There was no association between a prolonged second stage in the index pregnancy and subsequent sPTB (aOR 0.70, 95% CI 0.13-3.83, p=0.7). The risk of subsequent sPTB was threefold for those with a second stage caesarean section; however this did not reach statistical significance. CONCLUSIONS A prolonged second stage of labour in the index pregnancy is not associated with an increased risk of subsequent sPTB. A second stage caesarean section in the index pregnancy may be associated with an increased risk of subsequent sPTB, however there was no statistically significant difference. These findings are important for counseling and suggest that the effects of these factors are not clinically significant to justify additional interventions in the subsequent pregnancy.

Abstract
Purpose: Evaluation of simplified Bishop score and ultrasound cervicometry in the assessment of labor induction success in nulliparous women.Methods: Prospective cohort study included 146 nulliparous women with singleton pregnancy and indications for labor induction. Prior to labor induction, cervicometry and Bishop score were determined. Upon delivery, patients were classified as those delivered vaginally and by cesarean section (CS) after unsuccessful labor induction.Results: Bishop score >5 was found in 47.95% of vaginally delivered women and 12.33% of patients delivered by CS (p < .01). Cervicometry had appropriate findings in 34.2% of vaginally delivered women and 75.3% of those delivered by CS (p < .01). Bishop score (>5 versus ≤5) had lower sensitivity (52.05%) and specificity (12.33%) than cervicometry (good versus unfavorable findings) (sensitivity 65.75%, specificity 75.34%) for prediction of labor induction success. If Bishop score was ≤5, cervicometry had 50.0% sensitivity and 78.13% specificity, while if Bishop score was >5, 82.86% sensitivity and 55.56% specificity. Obtained model for predicting labor induction outcome in nulliparous women based on their clinical and ultrasonographical characteristics identified the Bishop score as the most important predictor.Conclusions: Study confirmed the usefulness of simplified Bishop score and ultrasound cervicometry in the assessment of labor induction success in nulliparous women.

Abstract
INTRODUCTION This study investigates associations between maternal body mass index (BMI) early in pregnancy and obstetric interventions, maternal and neonatal outcomes. MATERIAL AND METHODS This is a cohort study of nulliparous women originally included in a cluster randomized controlled trial carried out at 14 Norwegian obstetric units between 2014 and 2017. The sample included 7189 nulliparous women with a singleton fetus, cephalic presentation and spontaneous onset of labor at term, denoted as group 1 in the Ten-Group Classification System. The women were grouped according to the World Health Organization BMI classifications: underweight (BMI <18.5), normal weight (BMI 18.5-24.9), pre-obesity (BMI 25.0-29.9), obesity class I (BMI 30.0-34.9), and obesity classes II and III (BMI ≥35.0). We used binary logistic regression to estimate crude and adjusted odds ratios (ORs) of the interventions and outcomes, with associated 95% confidence intervals (CIs), comparing women in different BMI groups with women of normal weight. RESULTS We found an increased risk of intrapartum cesarean section in women of obesity class I and obesity classes II and III, with adjusted OR of 1.70 (95% CI 1.21-2.38) and 2.31 (95% CI 1.41-3.77), respectively. Women in obesity groups had a gradient of risk of epidural analgesia and use of continuous CTG (including STAN), with adjusted OR of 2.39 (95% CI 1.69-3.38) and 3.28 (95% CI 1.97-5.48), respectively. Women in obesity classes II and III had higher risk of amniotomy (adjusted OR = 1.42, 95% CI 1.02-1.96), oxytocin augmentation (adjusted OR = 1.54, 95% CI 1.11-2.15), obstetric anal sphincter injuries (adjusted OR = 2.21, 95% CI 1.01-4.85) and postpartum hemorrhage ≥1000 mL (adjusted OR = 2.20, 95% CI 1.29-3.78). We found a reduced likelihood of spontaneous vaginal delivery for pre-obese women (adjusted OR = 0.85, 95% CI 0.74-0.97) and no associations between maternal BMI and neonatal outcomes. CONCLUSIONS Obese women in Ten-Group Classification System group 1 had increased risks of obstetric interventions and maternal complications. There was a gradient of risk for intrapartum cesarean section, with the highest risk for women in obesity classes II and III. No associations between maternal BMI and neonatal outcomes were observed.

Abstract
The aim of this review was to summarize the available evidence about the use of levonorgestrel-releasing intrauterine system (LNG-IUS) as a contraceptive method in nulliparous women. For this purpose, studies evaluating the efficacy, safety, bleeding pattern, satisfaction and discontinuation of the levonorgestrel-releasing intrauterine system in nulliparous women were analyzed. Only original research articles published in English between 1990–27th March 2020 were considered eligible. Reviews, book chapters, case studies, conference papers, opinions, editorials and letters were excluded. The systematic literature search of PubMed/MEDLINE, Scopus, Embase and Cochrane Library databases identified 816 articles, 23 of which were analyzed. The available evidence indicates that LNG-IUS is an effective and safe contraceptive method for nulliparous women that achieves high levels of satisfaction among patients. Moreover, nulliparous women seem to experience fewer expulsions than parous ones. Bleeding pattern is acceptable for the majority of patients, and bleeding disorders mainly occur in the first months after the insertion. More in-depth, long-term prospective studies are needed in this patient group to determine risk factors for the occurrence of side effects and associated discontinuations, which should not, however, delay the wider use of the method in this group, given the number of advantages.

Abstract
BACKGROUND Underweight is still prevalent in developing countries like India. Prepregnancy body mass index (BMI) is used as the standard against which the measurements are made in pregnancy. AIM To study the association between early pregnancy BMI and feto-maternal outcome among nulliparous women. METHODOLOGY This is a prospective observational study, with a sample size of 294. The antenatal patients were categorized into four categories of BMI according to the WHO classification, and pregnancy outcomes were compared. Data were analyzed using SPSS Software Version 17.0. Statistical tools used were percentages and mean, and categorical variables were analyzed by Chi-square statistics. RESULTS 48.94% of the patients enrolled in the study had normal early pregnancy BMI, and 44.22% and 6.8% were underweight and overweight, respectively. Obese women who gained more weight were at a higher risk of preterm delivery, cesarean section, and more time required for resumption of normal routine. Underweight women were at higher risk of postterm delivery, low birth weight, and increased hospital stay. CONCLUSION Adverse maternal and fetal outcomes are seen more commonly with the extremes of BMI.
