Introduction: Mechanical cervical ripening methods are considered safer than prostaglandins. Many centers choose this method for pre-induction in pregnant patients with a previous cesarean section. Our objective was to compare efficacy and safety of two different mechanical ripening methods in prolonged pregnancies with a Bishop score ≤ 6 and a previous cesarean section. Methods: Non-randomized study during 6 years in which patients were divided in two cohorts: a first period of time (from November 2014 to November 2018) in which Foley catheter was used and a second period of time (from November 2018 to November 2020) in which double-balloon catheter (Cook® balloon) was the method employed. The same protocol was followed in both groups. Efficacy was defined by the achievement of active labor. Ripening success (changes in Bishop score and achievement of active labor), vaginal delivery rate and maternal and neonatal safety were recorded. Results: The double-balloon was placed in 43 patients and the Foley catheter was inserted in 129 patients. Cook catheter showed better Bishop score difference than Foley but with no statistically significance (3.09 vs 2.76, p=0.271). Active labor was achieved similarly in both groups (81.4% double-balloon vs 78.2% Foley catheter, p=0.726). Although there was a higher vaginal delivery rate in the double-balloon group (62.8%) compared with the Foley group (49.6%), the difference was not statistically significant (p=0.065). Time from catheter insertion to delivery was significantly shorter in the Foley group compared with Cook group (1704 vs 1903 minutes, p

OBJECTIVE: to study the true determinants of adverse perinatal outcome (APO) in term healthy mothers with normal cardiotocograph (CTG), evaluating the real influence of maternal age. MATERIAL AND METHODS: In a retrospective study, we assessed a group of 529 term healthy mothers with normal CTGs that regardless of maternal age, evolved spontaneously up to 41 ± 2 weeks. The result of the conservative management was evaluated by means of univariable and multivariable logistic regression analysis, determining the association of maternal age and other clinical and ultrasonographical parameters with APO. RESULT: In contrast with low CPR MoM (OR = 0.155, p = .014), induction of labor (OR = 2.273, p = .023) and low parity (OR = 0.494, p = .026), maternal age and birth weight centile did not prove to be true determinants of perinatal outcome. The multivariable model for prediction of APO using clinical parameters presented a sensitivity of 35% and 27% for a false positive rate of 10% and 5%, AUC 0.736 (95% CI 0.655-0.818), p < .0001). CONCLUSIONS: in healthy old mothers with normal CTGs at term, APO is determined by low CPR, the existence of labor induction and low parity, while no real influence was observed for maternal age, fetal smallness, and interval examination-delivery. These results do not support the current consensus on induction at earlier weeks to prevent adverse outcomes in all cases of advanced maternal age, advocating for a more individualized, customized, and less interventional management based on fetal hemodynamics.

To compare the expression of microRNA-185-5p (miR-185-5p) in normal foetuses and in foetuses with late-onset growth restriction (FGR) and to determine the factors influencing this expression. In a prospective study, 40 foetuses (22 of them with late-onset FGR and 18 with normal growth) were scanned with Doppler ultrasound after week 35 and followed until birth. Subsequently, blood samples from umbilical cords were collected after delivery to evaluate the expression of miR-185-5p using real-time qPCR. Finally, multivariable regression analysis was applied to determine the clinical and ultrasonographic factors influencing miR-185-5p expression in both normal and late-onset FGR foetuses. In comparison with normal foetuses, late-onset FGR foetuses expressed upregulation of miR-185-5p (2.26 ± 1.30 versus 1.27 ± 1.03 2^-ddCt, P = 0.011). Multivariable regression analysis confirmed that cerebroplacental ratio (P

COVID-19 was declared a pandemic and confinement with movement restriction measures were applied in Spain. Postnatal mental disorders are common but frequently undiagnosed, being a risk period to develop anxiety and depression symptoms. The aim of this study is to evaluate the impact of confinement as depressive and anxiety symptoms in pregnant women (PrW) and puerperal women (PuW) mental health, as well as obstetric and perinatal outcomes during this period.The self-administered survey consists of a total of 28 questions, the first 16 providing contextual information and the following ones corresponding to the GHQ-12 that has been evaluated in a binomial form. A logistic regression model has been used to assess whether the contextual variables acted as a protective or risk factor and its fitting has been represented by a receiver operating curve.Of the 754 PrW interviewed, 58.22% were screened positive. Confinement time for these was 54.93 ± 9.75 days. The risk factors that were identified after the refinement have been to have a worse general state of health, to be sadder and to be more nervous. Among the protectors have been found to have a higher Apgar 10 score and induction of labor. The area under the adjusted regression adjustment curve was 0.8056.Our results show a high prevalence of depression and anxiety symptoms with strict confinement measures. PrW and PuW must be considered a risk group to develop mental health disorders during disruption circumstances. Using a mental health screening tool could help to identify a group of patients with more risk and to carry out a careful monitoring to allow adequate management.

Objectives: The objectives of this study were to evaluate the diagnostic abilities of the cerebroplacental ratio (CPR) for the prediction of adverse perinatal outcome (APO) and cesarean section for intrapartum fetal compromise (CS-IFC) within 1 day of delivery. Design: Retrospective observational case-control study. Methods: This was a study of 254 high-risk fetuses attending the day hospital unit of a tertiary referral hospital that underwent an ultrasound examination at 32–41 weeks and gave birth within 1 day of examination. APO was defined as a composite of abnormal intrapartum fetal heart rate or intrapartum fetal scalp pH Results: CPR in multiples of the median (MoM) was a moderate predictor of APO (area under the curve [AUC] = 0.77, p < 0.0001) and CS-IFC (AUC = 0.82, p < 0.0001). The predictive abilities of the multivariable model for APO (AUC = 0.81, p < 0.0001) and CS-IFC (AUC = 0.82, p < 0.0001) did not differ from those of CPR alone . Limitations: The small number of cases and the scarcity of information concerning labor induction. Conclusion: In high-risk pregnancies, CPR MoM is a moderate predictor of APO and CS-IFC when performed within 24 h of delivery.

The objective is to identify obstetric and perinatal factors that could be significant predictors of ASD and may lead to early detection and intervention. A population-based case-control study including 128 children diagnosed with ASD and 311 controls was conducted. Information was collected through self-reported questionnaires. The factors retained as significant predictors for ASD in the final adjusted hierarchical logistic regression model were cesarean section and male gender. The study revealed a higher incidence of cesarean sections and male gender in children with ASD in comparison to unaffected children confirming the results of previous studies. Children born by cesarean section, especially males, should be more closely monitored for the presence of ASD traits for early diagnosis and intervention.

Objective:The objective was to evaluate maternal Mediterranean diet (MD) pattern adherence during pregnancy and its association with small for gestational age (SGA) and preterm birth. A secondary objective of the current study was to describe the sociodemographic, lifestyle and obstetric profile of the mothers studied as well as the most relevant paternal and newborn characteristics.Design:The current study is a two-phase retrospective population-based study of maternal dietary habits during pregnancy and their effect on newborn size and prematurity. The descriptive first phase examined maternal dietary habits during pregnancy along with the maternal sociodemographic, lifestyle and obstetric profile in a cross-sectional period study. In the second phase, newborn outcomes were evaluated in a nested case–control study. Adherence to MD during pregnancy was measured with the Spanish version of Kidmed index.Setting:Obstetrics ward of the La Fe Hospital in Valencia.Participants:All mother–child pairs admitted after delivery during a 12-month period starting from January 2018 were assessed for eligibility. A total of 1118 provided complete outcome data after signing informed consent.Results:14·5 % met the criteria of poor adherence (PA); 34·8 %, medium adherence (MA); and 50·7 %, optimal adherence (OA). Medium adherence to MD was associated in the adjusted scenarios with a higher risk of giving birth to a preterm newborn. No association was found between MD adherence and SGA.Conclusions:Early intervention programmes geared towards pregnant women, where women were aided in reaching OA to MD, might reduce the risk of preterm newborn.

Objective: It was the aim of this study to describe a micro­RNA (miRNA) profile characteristic of late-onset fetal growth restriction (FGR) and to investigate the pathways involved in their biochemical action. Methods: In this prospective study, 25 fetuses (16 normal and 9 with FGR [estimated fetal weight Results: The FGR fetuses expressed upregulation of two miRNAs: miR-25-3p and, especially, miR-148b-3p, a miRNA directly involved in Schwann cell migration, neuronal plasticity, and energy metabolism (p = 0.0072, p = 0.0013). Conclusions: FGR fetuses express a different miRNA profile, which includes overexpression of miR-25-3p and miR-148b-3p. This information might improve our understanding of the pathophysiological processes involved in late-onset FGR. Future validation and feasibility studies will be required to propose miRNAs as a valid tool in the diagnosis and management of FGR.

BACKGROUND: Cervical insufficiency is a recurrent, passive, and painless dilation of the cervix in the second trimester. The etiology is unclear, but there may be an association with subclinical intraamniotic infection. Interleukin-6 (IL-6) production in the amniotic cavity is induced by bacterial invasion, it is the major proinflammatory cytokine released in response to infection. Although the gold standard method to measure it is through an amniocentesis, the procedure constitutes an invasive technique with several associated risks. The objective of this study is to determine if there is a correlation between intraamniotic and vaginal IL-6 in patients with cervical insufficiency and bulging membranes during the second trimester of pregnancy, in order to avoid an amniocentesis before the rescue cerclage. METHODS: A cohort study was performed in which all patients with cervical insufficiency and bulging membranes admitted into our tertiary hospital between 2019 and 2020 were included, and a control group of asymptomatic women in the second trimester of gestation where studied at the same time. Patients with bulging membranes underwent an amniocentesis to quantify amniotic IL-6, and a sample of vaginal fluid for vaginal IL-6 determination was obtained from both the study and the control group. RESULTS: A total of 20 women were included in each group. Median gestational age at diagnosis was 22 weeks in patients with bulging membranes, and 21 weeks in the control group. Vaginal IL-6 in control group (10.875 pg/mL) is much lower than the study group one (1308.77 pg/ml). In patients with bulging membranes, vaginal IL-6 expression was lower in the vagina than in the amniotic cavity [average IL-6 in the amniotic cavity 26890.07 pg/mL, vs 1308.77 pg/mL in the vagina (p < .01)]. Through a Spearman coefficient correlation rank [rho = 0.709 (p < .001)], there is a positive correlation between amniotic and vaginal IL-6 values. The best value of this correlation was calculated with the ROC curve, being the area under the curve 0.929 (CI 95% 0.721-0.995), and the cutoff of point less than 61.4 pg/ml (sensitivity 83.33%; specificity 92.86%). Patients with vaginal IL-6 < 61.4 pg/ml associated a longer latency time between diagnosis and delivery, a higher neonatal weight and a lower perinatal mortality. Rescue cerclage in vaginal IL-6 < 61.4 pg/ml was the best predictor of good pregnancy outcome. CONCLUSION: There is a correlation between intraamniotic and vaginal IL-6 in patients with cervical insufficiency and bulging membranes during the second trimester of pregnancy. However, further studies are needed in order to considerate the avoidance of an amniocentesis before an emergency cerclage.

Introduction: A controversy exists about the accuracy of the cerebroplacental ratio (CPR) for the prediction of cesarean section for intrapartum fetal compromise (CS-IFC). Our aim was to evaluate whether the interval to delivery modifies the accuracy of CPR either as a single marker or combined with estimated fetal weight centile (EFWc), type of labor onset (TLO), and other clinical variables. Methods: This was a multicenter retrospective study of 5,193 women with singleton pregnancies who underwent an ultrasound scan at 35+0–41+0 weeks and gave birth within 1 month of examination, at any of the participating hospitals in Spain, UK, and Italy. CS-IFC was diagnosed in case of an abnormal intrapartum fetal heart rate or intrapartum fetal scalp pH Results: The predictive ability of CPR MoM for CS-IFC worsened with the interval to delivery. In general, the best prediction was obtained prior to labor and by adding information related to EFWc and TLO (AUC 0.71 [95% CI: 0.64–0.79], 0.73 [95% CI: 0.66–0.80], and 0.75 [95% CI: 0.69–0.81]; p < 0.0001). Addition of more clinical data did not improve prediction. In addition, results did not vary when only cases with spontaneous onset of labor were studied. Conclusion: CPR MoM prediction of CS-IFC at the end of pregnancy worsens with the interval to delivery. Accordingly, it should be done in the short term and considering EFWc and TLO.

The objective was to evaluate the best predictors of adverse perinatal outcome (APO) in foetuses examined up to 34 weeks and delivered by spontaneous or induced labour. This was a retrospective study of 129 pregnancies that underwent an ultrasound Doppler examination at 23-34 weeks and entered into labour within 30 days. Cerebroplacental ratio (CPR) and mean uterine artery pulsatility index (mUtA PI) were converted into multiples of the median (MoM) and estimated foetal weight (EFW) into centiles to adjust for gestational age (GA). Sonographic and clinical parameters were evaluated using logistic regression analysis.The multivariable model for the prediction of APO presented a notable accuracy: Detection rate (DR) was 39.5% for a false positive rate (FPR) of 5% and 56.8% for a FPR of 10%, AUC 0.82, p < .0001. Significant predictors were GA, EFW centile, and CPR MoM, but not mUtA PI MoM. Moreover, the type of labour onset did not exert any influence on APO. In conclusion, up to 34 weeks, prediction of APO after spontaneous or induced labour may be done measuring CPR and EFW.IMPACT STATEMENTWhat is already known on this subject? Earlier in pregnancy, foetal growth restriction is caused by placental disease causing progressive hemodynamic changes. These changes have been exhaustively described. Conversely, information about the best predictors of adverse outcome is scarce.What do the results of this study add? The findings of this study show that prior to 34 weeks and up to 1 month before labour, labour outcome might be predicted by gestational age, foetal cerebroplacental ratio (CPR) and estimated foetal weight (EFW).What are the implications of these findings for clinical practice and/or further research? If CPR behaves as a good marker of outcome not only at the end of pregnancy but also earlier in gestation, it might be interrogated along with EFW in foetuses attempting vaginal delivery to determine the risk of adverse outcome.

In a prospective study, 48 fetuses were evaluated with Doppler ultrasound after 34 weeks and classified, according to the cerebroplacental ratio (CPR) and estimated fetal weight (EFW), into fetuses with normal growth and fetuses with late-onset fetal growth restriction (LO-FGR). Overexpression of miRNAs from neonatal cord blood belonging to LO-FGR fetuses, was validated by real-time PCR. In addition, functional characterization of overexpressed miRNAs was performed by analyzing overrepresented pathways, gene ontologies, and prioritization of synergistically working miRNAs. Three miRNAs: miR-25-3p, miR-185-5p and miR-132-3p, were significantly overexpressed in cord blood of LO-FGR fetuses. Pathway and gene ontology analysis revealed over-representation of certain molecular pathways associated with cardiac development and neuron death. In addition, prioritization of synergistically working miRNAs highlighted the importance of miR-185-5p and miR-25-3p in cholesterol efflux and starvation responses associated with LO-FGR phenotypes. Evaluation of miR-25-3p; miR-132-3p and miR-185-5p might serve as molecular biomarkers for the diagnosis and management of LO-FGR; improving the understanding of its influence on adult disease.

Background: Smoking during pregnancy is a public health problem worldwide and the leading preventable cause of fetal morbidity and mortality and obstetric disease. Although the risk of tobacco-related harm can be substantially reduced if mothers stop smoking in the first trimester, the proportion of women who do so remains modest; therefore, the treatment of smoking in pregnant women will be the first therapeutic measure that health professionals should adopt when providing care to pregnant women. The recommendation of nicotine replacement therapy during pregnancy remains controversial due to the potential effects on the health of the fetus. Purpose: The aim of this review was to provide an overview of human studies about the use of nicotine replacement therapy during pregnancy, evaluating the efficacy and safety of the different formulations. Methods: The electronic databases PubMed and EMBASE were searched from May 2012 to May 2022. A total of 95 articles were identified through database searching using a combination of keywords. Out of 79 screened articles and after the removal of duplicates, 28 full-text articles were assessed for eligibility and 12 articles were finally included for review. Results: Although demonstrated to be effective in adult smokers, evidence in support of NRT in pregnant women is limited. The results of the apparent safety of the use of NRT during pregnancy contradict the FDA classification of the different NRT formulations. Faster-acting formulations seem to be the safest and even most beneficial forms for the offspring. Conclusions: NRT is not completely harmless for the fetus or for the mother; however, if an adequate assessment of the risk-benefit binomial is made, its use during pregnancy to aid in quitting smoking does seem appropriate. It is necessary to establish individual recommendations on the formulation and dose to be used during pregnancy based on individual nicotinic needs.

To compare the accuracies of several sonographic parameters for the prediction of adverse perinatal outcome (APO) prior to delivery.This was a prospective study of fetuses attending the day hospital unit of a tertiary referral hospital that were scanned at 34-41 weeks and gave birth within 24 h of examination. APO was defined as a composite of abnormal intrapartum fetal heart rate or intrapartum fetal scalp pH7.20 requiring urgent cesarean section, neonatal umbilical cord pH7.10, 5' Apgar score7 and postpartum admission to neonatal or pediatric intensive care units. The accuracies of the middle cerebral, vertebral and umbilical arteries pulsatility index multiples of the median (MoM), the cerebroplacental and vertebroplacental ratios MoM and the EFW in centiles for the prediction of APO was evaluated by means of ROC curves and logistic regression analysis.A total of 2140 fetuses were prospectively scanned, however only 182 entered into spontaneous or induced labor and were delivered within 24 h of examination. In this group, MCA PI MoM was the best predictor of APO (AUC = 0.76, 95% CI 0.66-0.85,In a high-risk population of third-trimester fetuses delivering within 24 h of examination, the outcome may be moderately anticipated just with the information provided by the cerebral flow.
