Analysis of the appropriateness of using the Robson Classification in a high-risk maternity ward in Brasília, Brazil

The Robson Classification is a tool designed to monitor cesarean section rates in diverse populations and assess the impact of management changes. This study aimed to evaluate the application of the Robson Classification in a high-risk maternity ward in Brasília, Brazil. A cross-sectional observational study was conducted, analyzing 1813 deliveries between January and June 2019 at the Materno Infantil Hospital in Brasília. The overall cesarean section rate was 55.7%, and Robson Group 5 significantly contributed to the global rate at 33.3%. It was concluded that there is an association with the type of delivery, newborn weight, and fetal disease, irrespective of the type. Regarding maternal conditions, an association was observed in Robson Group 10, which exhibited a 51.4% cesarean section rate. The use of the Robson Classification within the maternity context, despite being a local reference for high-risk pregnancies, indicated the potential for reducing cesarean rates in specific cases. A protocol based on the Robson Classification is proposed as an instrument for adjusting cesarean birth rates in all public maternity hospitals in the Federal District, Brasília, Brazil.

Analysis of adverse late-term pregnancy outcomes after cervical cold knife conization

Objective: To investigate the effects of cervical cold knife conization (CKC) on preterm delivery, other pregnancy complications and neonatal outcomes, and explore the relationship between preterm delivery risk and the depth and volume of conization. Methods: The clinical data and pregnancy outcomes of 272 women who underwent CKC in Peking Union Medical College Hospital from January 2002 to March 2018 (conization group) and 1 647 pregnant women who gave birth in Peking Union Medical College Hospital during January to December 2019 (control group) were collected. The preterm delivery, premature rupture of membranes, other pregnancy complications and neonatal outcomes of the two groups were compared, and the relationship between the depth and volume of conization and the risk of preterm delivery in postoperative singleton pregnancy was analyzed. Results: (1) There were no significant differences between the two groups in delivery age, parity, proportion of singleton pregnancy, proportion of assisted reproductive technology (all P>0.05). (2) The rate of preterm delivery in the conization group was significantly higher than that in the control group [14.8% (39/264) vs 5.7% (91/1 589); χ2=28.397, P<0.001]. There were still significant differences in preterm delivery rates between the two groups at <34 weeks and 34-37 weeks (all P<0.01). There was no significant difference in the incidence of premature rupture of membrane between the two groups [23.5% (62/264) vs 23.4% (372/1 589); χ2=0.001, P=0.979], but the incidence of preterm premature rupture of membrane in the conization group was significantly higher than that in the control group [11.4% (30/264) vs 2.2% (35/1 589); χ2=56.132, P<0.001]. (3) The rate of cesarean section in the conization group was higher than that in the control group [59.6% (162/272) vs 38.8% (639/1 647); χ2=41.377, P<0.001]. The birth weight of preterm infants in the conization group was significantly higher than that in the control group [(2 409±680) vs (2 150±684) g; t=2.184, P=0.030]. However, there were no statistically significant differences in the incidence of gestational diabetes mellitus, hypertensive disorders in pregnancy, the birth weight of full-term infants, incidence of small for gestational age infant and neonatal intensive care unit admission rate between the two groups (all P>0.05). (4) The preterm delivery rates of coning depth >15 mm, cone size ≥2 cm3 and cone size <2 cm3 were higher than that in the control group (all P<0.05). When the coning depth ≤15 mm, the preterm delivery rate in the conization group was higher than that in the control group, but there was no significant difference (P=0.620). The rate of preterm delivery of pregnant women with coning depth >15 mm was significantly higher than those with coning depth ≤15 mm (RR=3.084, 95%CI: 1.474-6.453; P=0.001). There was no significant difference in the preterm delivery rate between pregnant women with cone size >2 cm3 and those with cone size ≥2 cm3 (RR=1.700, 95%CI: 0.935-3.092; P=0.077). Conclusion: The risk of preterm delivery and preterm premature rupture of membranes in subsequent pregnancies are increased after cervical CKC, and the risk of preterm delivery is positively correlated with the depth of cervical coning.

Analysis of the Effect of Midwives’ Psychological Care Intervention on the Progress of Labor and Cesarean Rate of Elderly Women in Labor

Objective: To analyze the effect of midwife psychological nursing intervention in the clinical care of elderly women in labor. Methods: According to the order of admission, 74 elderly women were divided into the control group and the observation group. In addition to the routine perinatal nursing interventions, the observation group strengthened the implementation of midwives’ psychological nursing interventions. The duration of labor, mode of delivery, psychological state, and stress response indexes of the two groups were analyzed and compared. Results: The observation group had a shorter duration of all labor stages and total duration of labor than the control group, a lower cesarean section rate than the control group, and a higher degree of improvement in anxiety, depression, and stress response indexes in the 3-day postpartum period as compared to the control group (P &lt; 0.05). Conclusion: The implementation of midwife psychological care intervention in perinatal care of elderly women can further shorten the duration of labor, reduce the cesarean section rate, and improve the psychological state and stress indicators, which is worth promoting.

The effect of continuous electronic fetal monitoring on mode of delivery and neonatal outcome among low-risk laboring mothers at Debre Markos comprehensive specialized hospital, Northwest Ethiopia.

Electronic fetal heart rate monitoring (EFM) has been widely used in obstetric practice for over 40 years to improve perinatal outcomes. Its popularity is growing in Ethiopia and other sub-Saharan African countries to reduce high perinatal morbidity and mortality rates. However, its impact on delivery mode and perinatal outcomes in low-risk pregnancies remains controversial. This study aimed to assess the effect of continuous EFM on delivery mode and neonatal outcomes among low-risk laboring mothers at Debre Markos Comprehensive Specialized Hospital, Northwest Ethiopia. A prospective follow-up study was conducted from November 20, 2023, to January 10, 2024. All low-risk laboring mothers meeting the inclusion criteria were included. Data were collected via pretested structured questionnaires and observation, then analyzed using Epi-data 4.6 and SPSS. The incidences of cesarean delivery and continuous EFM were compared using the chi-squared test and Fisher's exact test. The study found higher rates of instrumental-assisted vaginal delivery (7% vs. 2.4%) and cesarean sections (16% vs. 2%) due to unsettling fetal heart rate patterns in the continuous EFM group compared to the intermittent auscultation group. However, there were no differences in immediate neonatal outcomes between the groups. When compared to intermittent auscultation with a Pinard fetoscope, the routine use of continuous EFM among low-risk laboring mothers was associated with an increased risk of cesarean sections and instrumental vaginal deliveries, without significantly improving immediate newborn outcomes. However, it is important to note that our study faced significant logistical constraints due to the limited availability of EFM devices, which influenced our ability to use EFM comprehensively. Given these limitations, we recommend avoiding the routine use of continuous EFM for low-risk laboring mothers to help reduce the rising number of operative deliveries, particularly cesarean sections. Our findings should be interpreted with caution, and further research with adequate resources is needed to draw definitive conclusions.

X-ray Pelvimetry Has No Impact on the Outcomes of Trial of Labor after Cesarean Delivery: A Retrospective Single-center Study.

Few studies have examined the relationship between pelvic size and the success or failure of trial of labor after cesarean delivery (TOLAC). Here we aimed to determine whether pelvic size and morphological data obtained from radiography contribute to the first successful TOLAC. This retrospective single-center observational study enrolled pregnant women who underwent TOLAC between 2010 and 2021. The results of X-ray pelvimetry data, including obstetric conjugate (OC), transverse diameter of the pelvic inlet (TD), anteroposterior diameter of the pelvic inlet (APD), shape of the pelvic inlet, and other obstetrical clinical data, were compared between the success and failure groups. Seventy-five patients in successful group after excluding 35 patients with previous successful TOLAC, and 21 patients in failure group were eligible. The failure group had a higher rate of previous cesarean sections due to failed labor trials (p = 0.042) and heavier newborns (p = 0.014). OC, TD, and APD on X-ray pelvimetry did not differ significantly between the two groups nor did the shape of the pelvic inlet affect the success rate for TOLAC. The generalized linear model identified a history of failed trials of labor as a significant predictor of failed TOLAC (odds ratio, 0.26; 95% confidence interval 0.071-0.923; p = 0.037), whereas no pelvimetric parameters were found. Pelvic size and morphological findings have no discernible impact on the outcomes of TOLAC. The universal application of X-ray pelvimetry in all women attempting TOLAC may not have significant clinical relevance.

A Comparative Study of Women’s Preference of Vaginal Delivery &amp; Cesarean Delivery among Primi Mother who are Attending Antenatal OPD in Murshidabad Medical College &amp; Hospital, Murshidabad

Caesarean section is already quite common in developed country but it has gradually become common in developing country also. In terms of developing countries in India the caesarean section rates havecrossed10-15% (Recommended by WHO) which cause a severe public health concern. Even though caesarean section causes many complications &amp;it's expensive, needed extra resources and observations, still the rate has increased from around7%(in1991) to 21% (in2021) &amp;it is more likely that it may goes up to 29% within just few more years.  Objectives- To assess the preferences and existing knowledge of vaginal delivery &amp;caesarean section among primipara mothers.  Methodology- A Non-experimental quantitative study with cross- sectional research design includes 100 primigravida mother through convenient sampling who has attended OPD clinic of Murshidabad Medical College &amp; Hospital, West Bengal.  Results- The study results shows that majority of participants (82%) preferred vaginal delivery. But the preference of caesarean section is higher in primigravida between age group18-22years comparative to older primigravida and also the primigravida from urban community has preferred caesarean section(66.6%) over normal vaginal delivery. Those who preferred Caesarean section were influenced by fear of pain during the labour (18%) and14%feltit was safe for the baby.  Conclusion- Young generation and urban community are more interested in caesarean section due to fear of pain and injury to baby. Especially commercial private practices also provoke the normal people for the caesarean section by creating doubts and misleading them. Government and women need to develop a positive attitude towards the normal vaginal delivery and measures have to be undertaken to create awareness towards safe mode of delivery.

The influence of epidural analgesic techniques on obstetrical outcomes

PurposeThe aim of this study is to compare and evaluate the obstetrical differences between three techniques, including the programmed intermittent epidural bolus (PIEB), the patient-controlled epidural analgesia (PCEA), and the continuous epidural analgesia (CEA).MethodsThis is a retrospective cohort study that investigates the obstetrical outcomes of 2240 patients who received EA during labor in a tertiary maternal unit over the course of 9 years (2011–2018). The only inclusion criterion was the use of epidural analgesia during childbirth and the only exclusion criteria were multiplets’ gestation. Multivariate logistic regression, Kruskal–Wallis test, and the log-rank test were utilized to compare the differences between the three EA techniques in terms of cesarean section rate, the incidence of perineal tears, the use of Oxytocin, the duration of labor, and the incidence of paresthesia.ResultsOut of the 2240 included deliveries; 1084 utilized PIEB, 1086 PCEA, and 70 CEA techniques. The incidence of Cesarean section was the highest in the CEA group (45.7%) compared to PIEB (24.8%) and PCEA (24.4%) P < 0.001. A significantly shorter duration of labor (vaginal delivery) was observed in the PCEA group (n: 821, 336.7 min) compared to the PIEB group (n: 814, 368.8 min) P < 0.001. There were no statistically significant differences in the incidence of perineal tears, the need of uterotonics, and the incidence of paresthesia.ConclusionThe results of this study indicate that the PIEB and PCEA techniques are superior to the CEA technique when it comes to analgesia during childbirth. In this study, the PCEA technique seems to be the best-suited technique for childbirth, since it had a significantly shorter duration of labor than the PIEB technique.

New approach to niobia-modified borosilicate glasses for Cs waste immobilization

The use of nuclear materials is increasing in energy production, medicine, and environmental sectors. Following this trend, the generation of radioactive wastes is also increasing in the whole production cycle and use of this kind of materials. Among these, the 137Cs radionuclide presents a potential risk to human health due to its half-life time (30,2 years), high-level activity (1 TBq) and easiness to contaminate rivers, soil, and air. The immobilization of 137Cs in solid matrices has been an available option researched by several countries. In this context a new glass composition based on aluminoborosilicate glass modified with niobium (Nb) was used for the immobilization of cesium through adding Cs-loaded zeolite. Homogeneous vitreous wasteforms were improved with the growth of Nb content in the compositions. All compositions were able to keep up to 5.9 wt% Cs2O, previously adsorbed by zeolite A, and the immobilization efficiency was around 53%. Their structural analyses by Raman revealed a depolymerized and complex network structure, due to the presence of several cations including Cs. In turn, Nb reflected positively on the chemical resistance and thermal properties, by changing the distribution of silicate species. The wasteforms presented good glass forming ability and thermal stability up to 520 °C. Through the thermal treatment for devitrification, Cs atoms were stabilized into the Pollucite phase (CsAlSi2O6). Besides that, the wasteforms, preferably the one containing 8.0 mol% Nb, showed low elemental releases and leaching rates for Cs (1 × 10−3 g m2.day−1), after the leaching experiments at 90 °C for 7 days in static conditions, verified by the neutron activation analysis (NAA).

Earlier Menarche in Greek Girls Born by Caesarean Section: A Case-Control Study.

Objectives: The purpose of this study was to report on the menarcheal age in girls of Greek origin and assess its potential associations with their demographic and perinatal data, as well as their maternal menarcheal age. Methods: In this case-control study, adolescent girls were recruited between September 2021 and September 2022 from two Pediatric Endocrinology Units, Aristotle University of Thessaloniki, Greece. Eligible participants included Greek girls up to the age of 18 years, with menarche and the absence of chronic disease or chronic medication use. Participants were divided into two groups, the early menarche group and the control group (menarche before or after 11 years of age, respectively). Data included participants' maternal menarcheal age, their chronological age, place of residence, anthropometric data (at recruitment) and perinatal data (birth order, gestational age, type of delivery, birth weight/length). Results: A total of 100 girls aged 7-17 years (mean age ± SD 12.51 ± 2.59 years) were included in this study. The mean ± SD menarcheal age of the total sample was 11.47 ± 1.55 years (median 11.20 years; range 7.50-16.25 years); 43% had early menarche (median menarcheal age 10.50 years; range 7.50-10.91 years), and 57% had menarche after age 11 (median menarcheal age 12.08 years; range 11.00-16.25 years). The caesarean section rate was significantly (p < 0.001) higher in girls with early menarche (83.7%) than controls, whereas other variables did not differ significantly between groups. Conclusions: This Greek sample demonstrated a relatively young age at menarche with a significant proportion of girls with early menarche; in the latter group, the rate of caesarian sections was significantly higher than controls.

Comparison of perinatal and neonatal outcomes of symptomatic pregnancy infected with SARS-CoV-2.

In this study, maternal and neonatal outcomes of pregnant women with positive severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) RNA tests were evaluated according to their symptomatic status. The clinical progression of SARS-CoV-2-positive pregnant women and the effect of coronavirus disease-2019 (COVID-19) on newborns was investigated. This retrospective cohort study was conducted at a tertiary pandemic hospital specializing in caring for pregnant women infected with SARS-CoV-2. We included patients with a positive SARS-CoV-2 polymerase chain reaction test at delivery, subdividing them into symptomatic and asymptomatic groups. Two hundred and forty-nine patients were included in the study. The mean age of the pregnant women in the symptomatic group was higher than those in the asymptomatic group (p=0.001). The iatrogenic preterm birth rates in the symptomatic and asymptomatic groups were 43.37% and 8.43%, respectively (p<0.001). Cesarean section rate was higher in symptomatic group (p=0.01). Maternal death was significantly higher in symptomatic pregnant women (p<0.001). The neonatal intensive care unit admission rate was higher in symptomatic pregnant women (p<0.001). The maternal and fetal outcomes for mothers with symptomatic infections tend to be worse, highlighting the importance of careful management, good follow-up and the advisability of closer monitoring.

Join point trends of instrumental vaginal deliveries and cesarean sections at the Lagos University Teaching Hospital, Lagos, Nigeria (2002-2017).

To determine the trends of instrumental vaginal delivery (IVD) and cesarean section (CS) at the Lagos University Teaching Hospital (LUTH), Nigeria, over 16 years, from 2002 to 2017. A retrospective cross-sectional study. The case records of all women who had IVD and CS during the study period were reviewed. The trends in the IVD and CS rates were evaluated using join point regression modeling. The average annual percent change (AAPC) and annual percent change (APC) with associated 95% confidence interval of segmental trends were calculated. The overall IVD rate was 1.36%. Vacuum delivery rate was higher than forceps (0.79% vs 0.57%). The CS rate was 44.9 per 100 deliveries; the rate increased by about 3.7% per annum. CS rates were 7.1-89.9 times the IVD rates within the study period. The number of IVDs performed in the hospital declined by about 83.02%, from 53 cases in 2002 to nine cases in 2017. Forceps delivery declined at a faster rate than vacuum delivery between 2002 and 2017 (AAPC for forceps: -12.6% [-17.5 to -7.5], P < 0.001 vs AAPC for vacuum: -6.2% [-14.3 to 2.7], P = 0.200). The commonest indication for IVD was prolonged second stage of labor (47/162, 29.01%) and shortening of the second stage of labor for maternal conditions (47/162, 29.01%). IVD rates are low and declining at LUTH. There is need to train accoucheurs on the safe use of IVDs to potentially reduce the CS rate.

Behavioral and genetic correlates of heterogeneity in learning performance in individual honeybees, Apis mellifera.

Learning an olfactory discrimination task leads to heterogeneous results in honeybees with some bees performing very well and others at low rates. Here we investigated this behavioral heterogeneity and asked whether it was associated with particular gene expression patterns in the bee's brain. Bees were individually conditioned using a sequential conditioning protocol involving several phases of olfactory learning and retention tests. A cumulative score was used to differentiate the tested bees into high and low performers. The rate of CS+ odor learning was found to correlate most strongly with a cumulative performance score extracted from all learning and retention tests. Microarray analysis of gene expression in the mushroom body area of the brains of these bees identified a number of differentially expressed genes between high and low performers. These genes are associated with diverse biological functions, such as neurotransmission, memory formation, cargo trafficking and development.

Effectiveness and Safety of the Double Intracervical Balloon vs Dinoprostone in Patients with Previous Cesarean Section.

To compare effectiveness and safety of the Cook's balloon with vaginal dinoprostone to induce labor in patients with previous cesarean section. Observational, and retrospective study that included pregnant women at ≥ 37weeks' gestation, with unfavorable cervix, singleton pregnancy, intact membranes, and a previous cesarean section, who had undergone labor induction in the period 2014-2019. 170 patients (86 balloon-84 dinoprostone) were analyzed. The proportion of women achieving vaginal delivery within 24h was higher in the dinoprostone than in double-balloon group (RR, 3.24; 95% CI, 1.36-7.72). No significant differences were detected in the first 48h in vaginal deliveries (P = .749) or in cesarean section rates (P = .634). Nor were there differences in maternal or fetal safety profiles. A body mass index > 35 increased the risk of cesarean section by 1.53 times (P = .017) and a Bishop's test score < 3 by 1.91 times (P = .009). A vaginal delivery following a cesarean section decreased the probability of another cesarean section by 0.46 times (P = .039). Labor induction with vaginal dinoprostone achieves better vaginal delivery rates in the first 24h vs Cook's balloon. While the difference in uterine rupture rate did not reach significance, this was higher in women receiving prostaglandin.

Factors Affecting Elective and Non-elective Cesarean Sections: A Multinomial Regression Analysis Using Robson's Classification in a Southeast European Country.

Albania, a middle-income Southeast European country, is experiencing an increase in cesarean section rates. This study aims to analyze cesarean section practices in Albania using the Robson classification to identify patterns and provide insights into elective and non-elective cesarean trends. This retrospective cohort study was conducted at the University Hospital of Obstetrics and Gynecology "Koco Gliozheni" in Albania, a leading tertiary hospital, from January to May 2023, involving 5,315 consecutive women who delivered during this period, including both live births and stillbirths, with a gestational age minimum of 28 weeks to align with standards of viability. We defined a function to systematically evaluate each case based on multiple criteria: parity, fetal presentation, onset of labor, previous deliveries, number of fetuses, and gestational age according to the Robson classification. Multinomial multiple regression was used to estimate the relationship between each of the above-mentioned variables and the likelihood of each type of cesarean delivery compared to normal births. The participants' mean age was 28.2 years (59.6% <30 years vs. 40.4% ≥30 years), while gestational age varied (12.1% before 37 weeks, the majority (72.3%) between 37 and 40 weeks, and 15.6% > 40 weeks). In elective cesarean sections, maternal age (odds ratio (OR) = 1.06) and gestational age (OR = 1.13) were associated with increased odds, with women with previous cesarean deliveries showing significantly higher odds (OR = 20.6), breech position (OR = 15.7), and multiple pregnancies elevating odds (OR = 7.3), whereas in non-elective cesarean sections, similar associations were observed with slightly different odds ratios which were maternal age (OR = 1.07), gestational age (OR = 1.16), previous cesarean delivery (OR = 6.3), breech position (OR = 8.5), and multiple pregnancies (OR = 5.1). Significant disparities in cesarean section rates were observed across various groups, with rates ranging from as low as 0.74% in Group 1 to as high as 89.24% in Group 5, and notable contributions from Group 2 with a rate of 69.95% and Group 6 with a rate of 81.29%. In conclusion, this study emphasizes the significance of factors such as maternal age, gestational age, previous cesarean deliveries, fetal presentation, number of fetuses, and multiple pregnancies in impacting the rates of elective, non-elective, and overall cesarean sections in Albania, highlighting the need for targeted strategies to improve maternal and fetal health outcomes.

Maternal and Neonatal Outcomes in Pregnancies Positive for SARS-CoV-2: A Retrospective Study

Background: In December 2019, the COVID-19 pandemic began in Wuhan, China with the emergence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Based on evidence, pregnant women are more vulnerable to respiratory infections due to physiological changes in their bodies. Objectives: The purpose of this study was to investigate the outcomes for mothers and newborns in the Sistan and Baluchestan province who tested positive for SARS-CoV-2 during pregnancy. Methods: The current retrospective study assessed 100 SARS-CoV-2-positive pregnant women and 50 healthy controls from hospitals affiliated with Zahedan University of Medical Sciences during 2019 - 2020. The data included demographic, clinical, and neonatal details, which were analyzed using both descriptive and inferential statistics with SPSS software version 25. Results: Our findings revealed that preterm birth occurred in 37% of pregnancies with COVID-19, and other complications such as acute respiratory distress syndrome (21%) and stillbirth (10%) were also prevalent. The majority of mothers (24%) were asymptomatic, with shortness of breath identified as the primary symptom (17%). Cesarean section rates were 30%, and miscarriage occurred in 2% of cases. Notably, complications such as placental abruption, meconium aspiration, and cardiorespiratory arrest were infrequent. Compared to mothers in good health, the outcomes for the newborns showed a significant difference in preterm birth (37% vs. 14%, P = 0.004) and premature rupture of the membranes (13% vs. 2%, P = 0.035). Conclusions: This study emphasizes the increased risk of preterm birth and associated complications, along with varied maternal and neonatal outcomes in pregnancies positive for SARS-CoV-2. The findings contribute to the understanding of COVID-19's impact on pregnancy outcomes, urging further comprehensive investigations for enhanced insights and the development of improved maternal-fetal care strategies.

Programmed intermittent epidural bolus regimen vs continuous epidural infusion: a retrospective study of motor block and obstetric outcomes using the Robson’s Ten Group Classification System

BackgroundUse of a programmed intermittent epidural bolus (PIEB) regimen during labour is associated with several benefits over a continuous epidural infusion (CEI), including reduced local anaesthetic consumption and reduced risk of motor block. We hypothesise that the benefits of a PIEB regimen may vary according to the Robson Ten Group Classification System (TGCS). The aim of this study was to determine if introduction of a PIEB regimen was associated with reduced incidence of motor block. We also wished to examine changes in obstetric outcomes following PIEB introduction across the Robson TGCS. MethodsThis was a single-centre retrospective cohort study. Data were collected over two three-month periods before and after PIEB introduction. The primary outcome was the incidence of motor block. Maternal and obstetric outcomes across Robson Groups 1–4 were analysed. ResultsIntroduction of PIEB was associated with reduced incidence of motor block (28.4% (95% CI 25.7% to 31.3%) vs 22.4%, (95% CI 19.9% to 25.2%), difference 5.9% (95% CI 1.0% to 21.1%), P=0.003), with no association with changes in rates of caesarean section, operative vaginal delivery or other obstetric outcomes. Use of a PIEB regimen was associated with reduced incidence of motor block in Robson Group 4a (20.3% (16.0%, 28.0%) vs 12.0%, (7.6%, 16.4%), difference 9.9% (95% CI −17.4% to −2.4%) P=0.009). There were no significant changes in other outcomes assessed across Robson TGCS. ConclusionIntroduction of PIEB for maintenance of labour analgesia was associated with reduced incidence of motor block in our institution compared with CEI. Presenting results according to Robson’s TGCS in future studies may allow better elucidation of the impact of neuraxial analgesia on maternal and obstetric outcomes.

Relationship between ultrasound parameters of the umbilical and middle cerebral arteries and intrauterine fetal distress

BACKGROUND By comprehensively analyzing the blood flow parameters of the umbilical and middle cerebral arteries, doctors can more accurately identify fetal intrauterine distress, as well as assess its severity, so that timely interventions can be implemented to safeguard the health and safety of the fetus. AIM To identify the relationship between ultrasound parameters of the umbilical and middle cerebral arteries and intrauterine distress. METHODS Clinical data of pregnant women admitted between January 2021 and January 2023 were collected and divided into the observation and control groups (n = 50 each), according to the presence or absence of intrauterine distress. The ultrasound hemodynamic parameters of the uterine artery (UtA), fetal middle cerebral artery (MCA), and umbilical artery (UmA) were compared with neonatal outcomes and occurrence of intrauterine distress in the two groups. RESULTS Comparison of ultrasonic hemodynamic parameters, resistance index (RI), pulsatility index (PI), and systolic maximal blood flow velocity of UmA compared to diastolic blood flow velocity (S/D), revealed higher values of fetal MCA, PI, and S/D of UmA in pregnant women with UtA compared to controls (P &lt; 0.05), while there was no difference between the two groups in terms of RI (P &lt; 0.05) The incidence of a neonatal Apgar score of 8-10 points was lower in the observation group (66.7%) than in the control group (90.0%), and neonatal weight (2675.5 ± 27.6 g) was lower than in the control group (3117.5 ± 31.2 g). Further, cesarean section rate was higher in the observation group (70.0%) than in the control group (11.7%), and preterm labor rate was higher in the observation group (40.0%) than in the control group (10.0%). The incidence of fetal distress, neonatal growth restriction and neonatal asphyxia were also higher in the observation group (all P &lt; 0.05). CONCLUSION Fetal MCA, UmA, and maternal UtA hemodynamic abnormalities all develop in pregnant women with intrauterine distress during late pregnancy, which suggests that clinical attention should be paid to them, and monitoring should be strengthened to provide guidance for clinical intervention.

Analyzing the Expectant Management of Redefined Active Phase of Labor (WHO 2018 Guidelines) in Nulliparous Women: A Randomized Control Trial

BACKGROUND:The World Health Organization (WHO) in their 2018 guidelines favored a noninterventional approach toward the labor process. The active phase of labor will be initiated when the cervix is 5 cm dilated and during obsoleted use of a 1 cm/hour cervical dilation rate as a diagnostic test for abnormal birth outcomes.OBJECTIVES:The aim of the study is to compare an active interventional labor management approach to a noninterventional labor management approach in nulliparous parturient women in terms of need of intervention, mode of birth, and maternofetal outcome.METHODOLOGY:This randomized control study was conducted at a rural tertiary care hospital for a period of 1.5 years. Nulliparous low-risk pregnant women presenting in latent labor were randomly allocated into two groups on the basis of cervical dilation and labor intervention. WHO 2014 guidelines with partograph were followed in group 1, and 2018 WHO guidelines with labor care guide were followed in group 2.RESULT:Both the groups were comparable with age, parity, and Bishop score at the time of admission. The incidence rates of intervention in the active first stage of labor in group 1 and group 2 were 31% and 10% with an odds ratio of 0.192 (95% confidence interval [CI] [0.079, 0.466]), and the rates of lower segment cesarean section in both the groups were 17.6% and 5.8%, respectively. The odds ratio with 95% CI for postpartum hemorrhage and neonatal intensive care unit admission in group 1 compared with group 2 was 0.313 [0.061, 1.610] and 1.057 [0.143, 7.832], respectively.CONCLUSION:This study showed that the shifting of the active first-stage threshold by 1 cm and letting labor progress at its natural pace significantly reduced the need for intervention and affected the fetal and maternal outcome positively.

Ultrasound examination in antenatal diagnosis of placenta accreta spectrum

The rise in caesarean section rates worldwide has led to a great increase in placenta accreta spectrum cases. Accurate diagnostics of placenta accreta before delivery is still difficult, as one-half to two-thirds of placenta accreta cases remain undiagnosed until delivery. Domestic and foreign sources use the diagnostic accuracy of ultrasonography (US) as the most commonly used method for placenta accreta image because of its inexpensiveness, non invasiveness, and rapidness. In this review, we highlighted the possibilities of prenatal ultrasound diagnosis of placenta accreta. Diagnostic accuracy may be reduced due to posterior wall placenta location and a higher body mass index (BMI). US and MRI are highly specific and useful in diagnosing or ruling out placenta accreta. Unlike MRI, the accuracy of ultrasound depends on the qualification, and therefore single-center studies often overestimate the accuracy of ultrasound. It is necessary to continue studying diagnostic methods for placenta accreta in order to select logical obstetric tactics for managing pregnant women with this pathology.

Obstetric outcomes of patients with inflammatory bowel disease.

Inflammatory bowel diseases (IBD) are frequently diagnosed between the ages of 20 and 40, i.e. the most fertile period for women. The potential impact of IBD on pregnancy is therefore a frequent issue. To determine the impact of disease activity during pregnancy on the obstetric prognosis of women with IBD. Gastroenterological and obstetric data were collected for patients for all consecutive patients with IBD and pregnancy followed up at Amiens University Hospital (Amiens, France) between 2007 and 2021. Obstetrics outcome of patients with and without active disease were compared. One hundred patients were included (81 with Crohn's Disease for 198 pregnancies, 19 with Ulcerative Colitis for 37 pregnancies). Patients with active IBD (21 patients, 24 pregnancies) were more likely to be admitted to hospital during pregnancy (66.6, vs. 5.2% in the inactive IBD group; p < 0.001), to give birth prematurely (mean term: 36.77 weeks of amenorrhoea (WA) vs. 38.7 WA, respectively; p = 0.02) and to experience very premature delivery (before 32 WA: 12.5 vs. 1.4%, respectively; p = 0.02). Patients with active disease had a shorter term at birth (38.4 WA, vs. 39.8 WA in the inactive disease group; p < 0.0001), a lower birth weight (2707 g vs. 3129 g, respectively; p = 0.01) and higher caesarean section rate (54.2 vs. 16.9%, respectively; p = 0.03). Women with IBD patients are at risk of pregnancy related complications, especially when IBD is active. Controlling disease activity at conception and close monitoring of the pregnancy is essential to improve both gastroenterological and obstetric outcome.
