A prospective cohort study evaluating exclusive breastfeeding in late preterm infants.

BACKGROUND: Breastfeeding can be challenging in neonates born between 34 0/7 and 36 6/7 weeks gestation (late preterm). METHODS: This prospective cohort study aims to evaluate exclusive breastfeeding at discharge, at three and six months of life in late preterm infants, and to identify facilitators and challenges to it. We included late preterm neonates eligible for the rooming-in. Data about breastfeeding at discharge, at three and six months of life were collected. RESULTS: Two hundred and fourteen late preterm infants were included in the study. At discharge 70 infants (32.7%) were fed with human milk and 144 (67.2%) were not. Non-exclusive breastfeeding was more common in women who were primiparous, had hypertension, and who underwent cesarean sections. Non-exclusive breastfeeding was associated with a low birthweight (<2500 g), ≥2 blood glucose controls, weight loss >10%, and longer hospital stay. Early first latch-on and skin-to-skin contact were more frequently associated with exclusive human milk feeding (P<0.001). Late preterm neonates born at 35 weeks showed a significant increase in exclusive human milk feeding at 3 months compared to the rate at discharge (P=0.004). CONCLUSIONS: In this cohort, early first latch-on and immediate skin-to-skin contact resulted associated with exclusive human milk feeding. Despite formula-fed during hospitalization, infants born at ≥35 weeks gestation who were exclusively breastfed at follow-up increased.

Risk factors for stillbirth at term: an Italian area-based, prospective cohort study.

BACKGROUND: Stillbirth at term has great emotional impact on both parents and professionals. In developed countries, efforts to identify risk factors are mandatory to plan area-specific prevention strategies. OBJECTIVE: The aim of the study was to identify independent risk factors that contribute to stillbirth at 37 weeks' gestation or later. STUDY DESIGN: This was an area-based, prospective cohort study on pregnancy at term with enrolled from 2014 to 2021 in Emilia-Romagna, a north Italian region. Data were retrieved from both birth certificates and the Stillbirth Surveillance system database. To identify independent risk factors, a multivariate analysis using logistic regression was performed. A descriptive analysis of the causes of stillbirth is also reported. RESULTS: In the observation period, 246,437 babies born at term (including 260 stillbirths, giving a rate of 1.06/1000) were considered. The risk factors independently associated with stillbirth were small for gestational age babies (odds ratio, 2.58; 95% confidence interval, 1.88-3.53), pregnancy achieved though fertility treatments (odds ratio, 2.01; 95% confidence interval, 1.15-3.51), and delayed access to pregnancy services (odds ratio, 1.56; 95% confidence interval, 1.10-2.22). In multipara, the presence of a previous stillbirth (odds ratio, 3.91; 95% confidence interval, 1.98-7.72) was also associated with an increased risk for recurrence. Early- rather than late-term was an additional risk factor. The most frequent causes of death were placental and cord disorders (61/260 and 56/260, respectively). However, 28.1% of cases remain unexplained. CONCLUSION: The risks for stillbirth at term are known early in pregnancy or could be identified through tailored antenatal management, allowing effective preventive strategies to reduce preventable cases.

Exposure to Prolonged Rupture of Membranes at Term Increases the Risk for Ventilatory Support in Uninfected Neonates.

OBJECTIVE: The effects of prolonged rupture of membranes (ROMs) on perinatal outcomes are still unclear, and it remains controversial for the management of those labors. This study aims to evaluate how the exposure of pregnant women to a prolonged ROM (≥ 24 hours) affects maternal and neonatal outcomes. STUDY DESIGN: This retrospective cohort study included singleton pregnant women at term delivering between January 2019 and March 2020 in a tertiary hospital. All relevant sociodemographic, pregnancy, and perinatal variables (maternal age, prepregnancy body mass index, labor, and delivery outcomes) were collected anonymously. Data were compared between the "ROM < 24 hours" and "ROM ≥ 24 hours" study groups. RESULTS: A total of 2,689 dyads were included in the study and divided according to their ROM-delivery time: ROM <24 hours (2,369 women, 88.1%), and ROM ≥ 24 hours (320 women, 11.9%). Maternal baseline characteristics were comparable except for the rate of nulliparous women, which was significantly higher among patients with ROM ≥ 24 hours. No significant differences were found regarding infectious neonatal outcomes. However, mechanical ventilation and continuous positive airway pressure were more common among neonates born after ROM ≥ 24 hours. The greater likelihood of neonatal respiratory distress was also confirmed among infants born to Group-B Streptococcus-negative women with ROM ≥ 24 hours (15 out of 267 neonates, 5.6% vs. 52 out of 1,529 with ROM < 24 hours, 3.4%, p = 0.04). CONCLUSION: According to the actual expectant policy, prolonged ROM is associated with an increased risk of respiratory support in noninfected neonates. Further investigations are required to explain such an association. KEY POINTS: · The management of women with prolonged rupture of membranes is controversial.. · The exposure of pregnant women to a prolonged rupture of membranes affects neonatal outcomes.. · Prolonged rupture of membranes is associated with an increased risk of respiratory support, in group-B Streptococcus-negative neonates..

L-Arginine supplementation in pregnancy: a systematic review of maternal and fetal outcomes.

BACKGROUND/AIM OF THE STUDY: L-Arginine (L-Arg)/Nitric Oxide (NO) system is involved in the pathophysiology of relevant Obstetric conditions. This review aims at summarizing the effects of L-Arg supplementation in pregnancy looking at safety and efficacy. METHODS: We conducted a systematic review of the literature utilizing PubMed for studies published from inception to September 2022. The search included human and animal studies where L-Arg was supplemented pre-conceptionally or during pregnancy, by either oral or intravenous route. The main perinatal outcomes were focused. RESULTS: Among 1028 publications, 51 studies were eligible for inclusion, 25 were performed in women, and the remnant in animals. Compared to controls/placebo, the supplementation with L-Arg reduced the development of pre-eclampsia (four studies), decreased blood pressure, and reduced the need for antihypertensive drugs in women with Hypertensive Disorders of Pregnancy (HDP, eight studies). In women carrying growth retarded fetuses, L-Arg improved fetoplacental circulation, birth weight and neonatal outcomes (five studies), while in the case of threatened preterm birth, L-Arg reduced uterine contractions (two studies). In several animal species, L-Arg supplementation in pregnancy improved reproductive performance by increasing the litter number and size. Moreover, in pre-eclamptic and metabolic syndrome experimental models, maternal hypertension and fetal growth were improved. CONCLUSION: L-Arg displays biological activities in pregnancies complicated by HDP and growth restriction, both in women and animal models. L-Arg administration is safe and could be a candidate as an intervention beneficial to maternal and fetal outcomes, at least in moderate clinical disorders.

Women's perception of fetal movements and perinatal outcomes: results of a prospective cohort study.

BACKGROUND: Active fetal movements (AFMs) are a sign of the well-being of the baby during pregnancy and suggests the integrity of the cardiovascular, musculoskeletal, and nervous systems of the fetus. The abnormal perception of AFMs is associated with an increased risk of adverse perinatal outcomes such as stillbirth (SB) and brain damage. Several definitions of " decreased fetal movements" have been proposed, but none of them has been universally accepted. The aim of the study is to investigate the perinatal outcomes in relation to AFMs frequency and perception in term pregnancy with an ad hoc questionnaire administered to the women before delivery. STUDY DESIGN: This was a prospective case-control study on pregnant women at term referring to the Obstetric Unit of the University Hospital of Modena, Italy, between January 2020 and March 2020. A validated questionnaire was administered to women who agreed to participate in the study. Therefore, women were subdivided into the case and control groups: cases included women who experienced adverse perinatal outcomes (APO) such as perinatal mortality (SB and early neonatal mortality), operative delivery (cesarean section or vacuum) due to fetal distress, Apgar 5' < 7, neonatal resuscitation at birth and NICU Admission, while controls were women who experienced delivery and birth without APO in the same period. RESULTS: Seventy-seven cases and 178 controls that compiled the questionnaire were included in the analysis. Characteristics significantly associated with APO were low education (OR 1.57, CI 95% 1.11-2.22), nulliparity (OR 1.76, CI 95% 1.20-2.58), obesity (OR 1.55, CI 95% 1.10-2.17), neonatal male gender (OR 1.92 CI95% 1.33-2.78) and centile at birth (< 10° and >90°) (OR 2.77, 95%CI 2.17, 3.55). There was no association between any answer about strengths, frequency and vigor of perceived fetal movements and APO. Even any maternal perception of fetal hiccups or uterine contractions wasn't associated with APO. On the other hand, women who referred to frequent change positions during sleep (OR 1.55 CI95% 1.05-2.30) and women who snore (OR 1.43 CI95% 1.01-2.05) showed a statistically significant increase of APO. CONCLUSIONS: Our data confirm the significant association between modifiable risk factors (such as obesity and low education) and APO. Thus, healthcare providers should be aware of the importance of intervention in reducing obesity, therefore snoring and related sleep apnea syndrome. Finally, changing position during sleep while not the perception of modified/reduced fetal movements significantly could induce the worst obstetric outcomes.

Association of maternal Body Mass Index and parity on induced labor stages.

BACKGROUND: Obesity is a widespread pandemic and obstetric care must adapt to meet the needs of obese pregnant women. Little is known about the impact of Body Mass Index (BMI) on the induction of labor (IOL). Therefore, our objective was to evaluate if the duration of the first and second stages of IOL is affected by maternal BMI in nulliparous and multiparous women. METHODS: We included singleton pregnancies at term with cephalic presentation whose labor was induced from June 2018 to December 2019. Women were divided into two groups according to pre-pregnancy BMI in normal weight and obese women. RESULTS: A total of 668 women with IOL were included in the study, among them, 349 had a normal weight and 321 were obese. The first stage of labor was longer in obese multiparous than normal-weight women (normal weight 81.98±71.7 vs. obese 134.3±158.1 min, P=0.000), while the second stage resulted significantly shorter (normal weight 22.2±27.8 vs. obese 14.3±14.2 min, P=0.000). The total time elapsed from IOL beginning and delivery was significantly higher in obese nulliparous (normal weight 10.4±19.7 vs. obese 22.0±26.2 h, P=0.000). Operative vaginal deliveries, emergency cesarean section, and failed IOL resulted to be similar between the groups. CONCLUSIONS: Obese multiparous women have longer first stages of labor while shorter second stages. The total time for induced obese nulliparous to reach delivery is higher than the normal weight. It might be reasonable to reconsider the partographs according to maternal BMI in case of induced labor for future obstetric practice.

Supplementation of Probiotics in Pregnant Women Targeting Group B Streptococcus Colonization: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis aimed to determine if probiotic supplementation in pregnancy reduced maternal Group B streptococcus (GBS) recto-vaginal colonization in pregnant women at 35-37 weeks of gestation. Electronic databases (i.e., PubMed, MEDLINE, ClinicalTrials.gov, ScienceDirect, and the Cochrane Library) were searched from inception up to February 2022. We included RCTs assessing the effects of probiotic supplementation in pregnancy on GBS recto-vaginal colonization. The primary outcome was GBS-positive recto-vaginal cultures performed at 35-37 weeks of gestation. Secondarily, we evaluated obstetric and short-term neonatal outcomes. A total of 132 publications were identified; 9 full-length articles were reviewed to finally include 5 studies. Probiotic supplementation reduced vaginal GBS colonization: the GBS positive culture rate was estimated at 31.9% (96/301) in the intervention group compared to 38.6% (109/282) in the control group (OR = 0.62, 95% CI 0.40-0.94, I2 4.8%, p = 0.38). The treatment started after 30 weeks of gestation and was more effective in reducing GBS colonization (OR 0.41, 95% CI 0.21-0.78, I2 0%, p = 0.55). Probiotic administration during pregnancy, namely in the third trimester, was associated with a reduced GBS recto-vaginal colonization at 35-37 weeks and a safe perinatal profile. Whether this new strategy could reduce the exposition of pregnant women to significant doses of antibiotics in labor needs to be evaluated in other trials.

Stillbirth occurrence during COVID-19 pandemic: a population-based prospective study.

OBJECTIVES: Data collected worldwide on stillbirth (SB) rates during the Covid-19 pandemic are contradictory. Variations may be due to methodological differences or population characteristics. The aim of the study is to assess the changes in SB rate, risk factors, causes of death and quality of antenatal care during the pandemic compared to the control periods. METHODS: This prospective study is based on the information collected by the Emilia-Romagna Surveillance system database. We conducted a descriptive analysis of SB rate, risk factors, causes of death and quality of cares, comparing data of the pandemic (March 2020-June 2021) with the 16 months before. RESULTS: During the pandemic, the SB rate was 3.45/1,000 births, a value in line with the rates of previous control periods. Neonatal weight >90th centile was the only risk factor for SB that significantly changed during the pandemic (2.2% vs. 8.0%; p-value: 0.024). No significant differences were found in the distribution of the causes of death groups. Concerning quality of antenatal cares, cases evaluated with suboptimal care (5.2%) did not change significantly compared to the control period (12.0%), as well as the cases with less than recommended obstetric (12.6% vs. 14%) and ultrasound evaluations (0% vs. 2.7%). CONCLUSIONS: During the COVID-19 pandemic, no significant differences in SB rates were found in an area that maintained an adequate level of antenatal care. Thus, eventual associations between SB rate and the COVID-19 infection are explained by an indirect impact of the virus, rather than its direct effect.

Nutraceuticals and polycystic ovary syndrome: a systematic review of the literature.

BackgroundThis study proposes a review of nutraceuticals used in the treatment of typical symptoms of Polycystic Ovary Syndrome (PCOS).The aim is to provide a classification of the most widely used nutraceutical supplements identifying the most effective nutraceuticals on glucose and insulin metabolism, the androgenic hormone profile, fertility, ovulatory capacity, inflammation, and oxidative stress.Material and MethodsWe included randomized controlled trials on PCOS patients undergoing administration of nutraceuticals, in particular vitamin D, vitamin E, probiotics, and inositols. These administrations are variable in terms of dosage, single supplementation, or combined with other compounds, dosage, and duration of the intervention.ResultsThe supplementation of inositols, at the physiologic ratio of 40: 1 of myo- and D-chiro-inositols, resulted to be the most effective in improving the glucose homeostasis and fertility, with a restoration of ovulatory capacity and menstrual regularity. Other nutraceuticals are particularly effective in reducing hyperandrogenism, with promising results demonstrated by the combinations of vitamin D and probiotics, vitamin E and coenzyme Q10, and the enrichment of inositol therapy with group B vitamins. An improvement in the inflammatory status and antioxidant capacity is obtained with the co-supplementation of probiotics and selenium or with vitamin E combined with omega 3.ConclusionsInositol supplementation is effective in the treatment of insulin resistance and fertility. Probiotics reduced hyperandrogenism, inflammatory and oxidative conditions, and resulted more effective when combined with selenium. Although these results proved to be satisfactory, further studies are needed with larger samples and a more homogeneous analysis of the outcomes.

Perinatal outcomes in twin late preterm pregnancies: results from an Italian area-based, prospective cohort study.

BACKGROUND: Multiple gestations represent a considerable proportion of pregnancies delivering in the late preterm (LP) period. Only 30% of LP twins are due to spontaneous preterm labor and 70% are medically indicated; among this literature described that 16-50% of indicated LP twin deliveries are non-evidence based. As non-evidence-based delivery indications account for iatrogenic morbidity that could be prevented, the objective of our observational study is to investigate first neonatal outcomes of LP twin pregnancies according to gestational age at delivery, chorionicity and delivery indication, then non evidence-based delivery indications. METHODS: Prospective cohort study among twins infants born between 34 + 0 and 36 + 6 weeks, in Emilia Romagna, Italy, during 2013-2015. The primary outcome was a composite of adverse perinatal outcomes. RESULTS: Among 346 LP twins, 84 (23.4%) were monochorionic and 262 (75.7%) were dichorionic; spontaneous preterm labor accounted for 85 (24.6%) deliveries, preterm prelabor rupture of membranes for 66 (19.1%), evidence based indicated deliveries were 117 (33.8%), while non-evidence-based indications were 78 (22.5%). When compared to spontaneous preterm labor or preterm prelabor rupture of membranes, pregnancies delivered due to maternal and/or fetal indications were associated with higher maternal age (p <  0.01), higher gestational age at delivery (p <  0.01), Caucasian race (p 0.04), ART use (p <  0.01), gestational diabetes (p <  0.01), vaginal bleeding (p <  0.01), antenatal corticosteroids (p <  0.01), diagnosis of fetal growth restriction (FGR) (p <  0.01), and monochorionic (p <  0.01). Two hundred twenty-six pregnancies (65.3%) had at least one fetus experiencing one composite of adverse perinatal outcome. Multivariate analysis confirmed that delivery indication did not affect the composite of adverse perinatal outcomes; the only characteristic that affect the outcome after controlling for confounding was gestational age at delivery (p <  0.01). Moreover, there was at least one adverse neonatal outcome for 94% of babies born at 34 weeks, for 73% of those born at 35 weeks and for 46% of those born at 36 weeks (p <  0.01). CONCLUSION: Our study suggests that the decision to deliver or not twins in LP period should consider gestational age at delivery as the main determinant infants' prognosis. Delivery indications should be accurately considered, to avoid iatrogenic early birth responsible of preventable complications.

Impact of endocrine disorders on stillbirth: a prospective cohort study.

OBJECTIVE: Among risk factors for SB, maternal endocrine diseases (ED), such as thyroids dysfunction and gestational diabetes mellitus (GDM), are the most frequent. This study aimed to investigate the rate of ED in a population of SB cases collected prospectively, and the relationship between these and causes of death. METHODS: This is an area-based, prospective cohort study conducted in Emilia-Romagna, Italy between January 2014 and December 2020. Data included all cases of SB (>22 weeks). RESULTS: From 2014 to 2020, 766 SB occurred out of a total of 232.506 births (SB rate:0.3/1000). The ED were present in 197/766 cases of SB (25.7%), respectively, 104 thyroid disease (52.8%), 74 GDM (37.5%), and 19 cases of concomitant GDM and thyroid disease (9.6%). Women who had SB associated with ED presented significantly higher mean maternal age (p < 0.001), BMI (p < 0.001), obesity (p < 0.001) and lower smoking habit (p = 0.02) respect with control group. Neonatal and placental weight of stillborn women with ED was significantly higher (p < 0.001) in respect to stillborn of the control group. Women with ED as associated condition (ReCODE classification), present significantly higher cases of SB caused by placenta pathologies (p = 0.009) namely abruptio placentae (p = 0.001) respect than control group. CONCLUSIONS: ED was more frequent in older and obese women experiencing SB. The main cause of death was abruptio placentae. This information can be helpful when counseling mothers with ED and planning antenatal management to prevent SB.

Implementation of guidelines about women with previous cesarean section through educational/motivational interventions.

OBJECTIVE: To investigate the effect of a quality improvement project with an educational/motivational intervention in northern Italy on the implementation of the trial of labor after cesarean section (CS). METHOD: A pre-post study design was used. Every birth center (n = 23) of the Emilia-Romagna region was included. Gynecologist opinion leaders were first trained about Italian CS recommendations. Barriers to implementation were discussed and shared. Educational/motivational interventions were implemented. Data of multipara with previous CS, with a single, cephalic pregnancy at term, were collected during two periods, before (2012-2014) and after (2017-2019) the intervention (2015-2016). The primary outcome was the rate of vaginal birth after CS (VBAC) and perinatal outcomes. RESULTS: A total of 20 496 women were included. The VBAC rate increased from 18.1% to 23.1% after intervention (P < 0.001). The likelihood of VBAC-adjusted for age 40 years or older, Caucasian, body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) at least 30, previous vaginal delivery, and labor induction-was increased by the intervention by 42% (odds ratio 1.42, 95% confidence interval 1.31-1.54). Neonatal well-being was improved by intervention; neonates requiring resuscitation decreased from 2.1% to 1.6% (P = 0.001). CONCLUSION: Educating and motivating gynecologists toward the trial of labor after CS is worth pursuing. Health quality improvement is demonstrated by increased VBAC even improving neonatal well-being.

First-trimester prediction model for placental vascular disorders: An observational prospective study.

This study aims to develop a multivariable predictive model for the risk of placental vascular complications (PVC), by using biochemical, biophysical, anamnestic and clinical maternal features available at the first trimester. PVC include gestational hypertension, preeclampsia, placenta abruption, intrauterine growth restriction (IUGR), and stillbirth. Prospective study that included all singleton pregnancies attending the first-trimester aneuploidy screening (11 +0-12 +6 weeks) at Obstetrics Unit of the University Hospital of Modena, in Northern Italy, between June 2018 and December 2019. In a total of 503 women included in the analysis, 40 patients were in the PVC group. The final prediction model for PVC included the following independent variables: pre-pregnancy BMI ≥ 30 (OR = 2.65, 95% CI = 1.04; 6.75, p = 0.0415), increasing values of mean arterial pressure (OR = 1.06, 95% CI = 1.02; 1.10, p = 0.0008), PAPP-A < 2.40465 U/L (OR = 0.43, 95% CI = 0.19; 0.96, p = 0.0388) and decreasing values of PlGf (MoM) (OR = 0.28, 95% CI = 0.10; 0.79, p = 0.0153). The area under the ROC curve was 79.4% indicating a satisfactory predictive accuracy. The best predictive cut-off for this score was equal to -2.562, which corresponds to a 7.2 % probability of having PVC. By using such a cut-off, the risk of PVC can be predicted in our sample with sensitivity equal to 82,4 % and specificity equal to 69,9 %. This model for early prediction of PVC is a promising tool to early identify women at greater risk for placenta vascular complications.

Chronic deciduitis in stillbirths: are there any specific clinical associations?

INTRODUCTION: Placental chronic deciduitis is a lesion consistent with the presence of plasma cells within the placental basal plate. It could be associated with adverse pregnancy outcomes, including stillbirth. METHODS: We retrospectively evaluated a cohort of 180 antepartum stillborn cases from singleton pregnancies, with the aim of investigating the clinical-histopathological relationship. Placental slides were reviewed following the standard protocol proposed by the "Amsterdam consensus statement". RESULTS: We observed an association between chronic deciduitis and lesions consistent with maternal vascular malperfusion, delayed villous maturation, villitis of unknown etiology and maternal autoimmunity. CONCLUSIONS: The observed clinical-histopathological associations suggest that an extensive maternal investigation could improve the comprehension of factors interfering with the placental development and the increasing risk of adverse pregnancy outcomes. HighlightsChronic deciduitis is associated with lesions consistent with maternal vascular malperfusionChronic deciduitis is associated with delayed villous maturationChronic deciduitis is associated with villitis of unknown etiologyChronic deciduitis is associated with maternal autoimmunity.

The role of vitamin D in metabolic and reproductive disturbances of polycystic ovary syndrome: A narrative mini-review.

Vitamin D is a secosteroid hormone that plays a pivotal role in several metabolic and reproductive pathways in humans. Increasing evidence supports the role of vitamin D deficiency in metabolic disturbances and infertility in women with polycystic ovary syndrome (PCOS). Indeed, supplementation with vitamin D seems to have a beneficial role on insulin resistance (IR) and endometrial receptivity. On the other hand, exceedingly high levels of vitamin D appear to play a detrimental role on oocytes development and embryo quality. In the current review, we summarize the available evidence about the topic, aiming to suggest the best supplementation strategy in women with PCOS or, more generally, in those with metabolic disturbances and infertility. Based on the retrieved data, vitamin D seems to have a beneficial role on IR, insulin sensitivity and endometrial receptivity, but high levels and incorrect timing of administration seem to have a detrimental role on oocytes development and embryo quality. Therefore, we encourage a low dose supplementation (400-800 IU/day) particularly in vitamin D deficient women that present metabolic disturbances like PCOS. As far as the reproductive health, we advise vitamin D supplementation in selected populations, only during specific moments of the ovarian cycle, to support the luteal phase. However, ambiguities about dosage and timing of the supplementation still emerge from the clinical studies published to date and further studies are required.

Fetal head malposition and epidural analgesia in labor: a case-control study.

BACKGROUND: The fetal head malposition in labor leads to prolonged labor, cesarean delivery and increased perinatal morbidity. Epidural analgesia has been associated with fetal head malposition, but it remains unknown if this relation is causal. OBJECTIVE: To compare the incidence of fetal malposition during labor and maternal/fetal outcomes, between women who received epidural analgesia with those who did not use the analgesic method. STUDY DESIGN: Case control study including 500 women with a single fetus in vertex position who gave birth at term at the Policlinic Hospital of Modena between May 2019 and July 2019. Two-hundred and fifty women belonged to the epidural analgesia (EA) group and 250 to the control group. RESULTS: The rate of posterior occiput positions occurred 4 times more frequently in the EA group than in the control group (8.8% vs 2.2%, p = .004). Cesarean sections were significantly higher in the EA group (11.6% vs 1.6%, p < .0000) as well as the need for augmentation with oxytocin (20% vs 8%, p = .0001) compared to the control group, in which spontaneous delivery prevailed instead. Women with epidural had labors that lasted on average 7.0 h against the 3.30 h of controls (p < .0000). The length of 2nd stage of labor was 55 vs 30 min (p = .009), respectively. No differences in blood loss and Apgar score between groups. Early breastfeeding was significantly higher among controls (82% vs 92.8%, p = .0004). CONCLUSIONS: Women receiving epidural analgesia in labor have higher rate of fetal malposition, prolonged labors, and more cesarean sections than controls. However, further studies are required to confirm a causal association between EA and fetal head malposition.

A first trimester prediction model for large for gestational age infants: a preliminary study.

BACKGROUND: Large for gestational age infants (LGA) have increased risk of adverse short-term perinatal outcomes. This study aims to develop a multivariable prediction model for the risk of giving birth to a LGA baby, by using biochemical, biophysical, anamnestic, and clinical maternal characteristics available at first trimester. METHODS: Prospective study that included all singleton pregnancies attending the first trimester aneuploidy screening at the Obstetric Unit of the University Hospital of Modena, in Northern Italy, between June 2018 and December 2019. RESULTS: A total of 503 consecutive women were included in the analysis. The final prediction model for LGA, included multiparity (OR = 2.8, 95% CI: 1.6-4.9, p = 0.001), pre-pregnancy BMI (OR = 1.08, 95% CI: 1.03-1.14, p = 0.002) and PAPP-A MoM (OR = 1.43, 95% CI: 1.08-1.90, p = 0.013). The area under the ROC curve was 70.5%, indicating a satisfactory predictive accuracy. The best predictive cut-off for this score was equal to - 1.378, which corresponds to a 20.1% probability of having a LGA infant. By using such a cut-off, the risk of LGA can be predicted in our sample with sensitivity of 55.2% and specificity of 79.0%. CONCLUSION: At first trimester, a model including multiparity, pre-pregnancy BMI and PAPP-A satisfactorily predicted the risk of giving birth to a LGA infant. This promising tool, once applied early in pregnancy, would identify women deserving targeted interventions. TRIAL REGISTRATION: ClinicalTrials.gov NCT04838431 , 09/04/2021.

Perinatal outcomes in women affected by different types of headache disorders: A prospective cohort study.

OBJECTIVE: This study aims to investigate pregnancy and perinatal outcomes in women with tension-type headache, migraine without aura and migraine with aura by comparing them to women without any headache disorders. STUDY DESIGN: Prospective cohort study including singleton pregnancies attending the first trimester aneuploidy screening at the University Hospital of Modena, in Northern Italy, between June 2018 and December 2019. RESULTS: A total of 515 consecutive women were included and headache disorders were reported in 43.5% of them (224/515). Tension-type headache was diagnosed in 24.3% of the cases, while 14% suffered from migraine without aura and 5.2% from migraine with aura. Birthweight was significantly lower in women affected by migraine with aura respective to other groups, and a significantly higher rate of small for gestational age infants was found in tension-type headache (10.4%) and in migraine with aura (24.9%) groups respective to the others (p < 0.001). Moreover, the admission to the neonatal intensive care unit was significantly higher in all the headache groups (p = 0.012). Multivariate analysis showed that women presenting tension-type headache (OR 4.19, p = 0.004), migraine with aura (OR 5.37, p = 0.02), a uterine artery pulsatility index >90th centile (OR 3.66, p = 0.01), low multiple of the median (MoM) of Pregnancy-associated plasma protein-A (PAPP-A) (OR 0.48, p = 0.05) and high MoM of Inhibin-A (OR 3.24, p = 0.03) at first trimester, are independently associated with the delivery of small for gestational age infants when compared to women without headache disorders. CONCLUSION: Migraine with aura and tension type headache expose women to an increased risk of delivering small for gestational age infants, in association with some utero-placenta markers evaluated at first trimester. These women with headache disorders have an additional indication to undergo first trimester aneuploidy screening and would possibly benefit from specific interventions.

Breastfeeding promotion and support: a quality improvement study.

BACKGROUND: Breastfeeding success is determined by early skin to skin contact, early initiation of breastfeeding, rooming-in, baby-led breastfeeding, creation of a favorable environment, specific training of health professionals, and continuity of care. OBJECTIVE: To investigate the women's satisfaction regarding the care and support received in the first days after childbirth. MATERIAL AND METHODS: A questionnaire of 24 items was administered to mothers before discharge, from May to September 2019 at the University Hospital of Modena. RESULTS: The predictive variables of exclusive breastfeeding were the delivery mode, age at birth and parity. The multivariate analysis showed that a high satisfaction score was associated with vaginal birth (OR=2.63, p=0.005), rooming-in during the hospitalization (OR=8.64, p<0.001), the skin to skin contact (OR=6.61, p=0.001) and the first latch-on within 1 hour after birth (OR=3.00, p=0.02). CONCLUSIONS: Mothers' satisfaction is one of the important factors of positive experience during hospital stay and of better health outcomes.
