RESUMO

OBJECTIVE: To determine whether equivocal prelabor rupture of membranes (PROM) cases are associated with adverse outcomes. METHODS: A retrospective study was conducted in a tertiary medical center between July 2012 and March 2022. The cohort comprised all women diagnosed with term PROM (≥37 gestational weeks), divided into two groups. (1) Certain PROM-suggestive history of a watery vaginal discharge confirmed by visualization of fluid leaking from the cervix or pooling in the vagina on speculum examination. (2) Uncertain PROM-suggestive history of a watery vaginal discharge not supported by speculum examination. All patients were hospitalized and gave birth spontaneously or following either expectant management for up to 24 h from PROM or induction. The primary outcome measure was cesarean delivery (CD) rate. Secondary outcome measures were adverse maternal/neonatal events. RESULTS: Of the 2012 women included in the study, 1750 had certain PROM and 262 uncertain PROM. CD rate was 5.8% in the certain PROM group and 8.8% in the uncertain PROM group; the difference was not statistically significant (P = 0.074). There was a significant between-group difference in the rate of CD due to failed induction on univariate analysis (0.69% vs 2.67%, respectively, P = 0.007), but it was not maintained on multivariate logistic regression (odds ratio 0.37, 95% confidence interval: 0.12-1.17). Other maternal and neonatal outcomes were similar in the two groups. CONCLUSION: Our findings indicate that following the same management guidelines for equivocal cases of ruptured membranes as for confirmed cases of term PROM did not compromise maternal or fetal outcomes.

RESUMO

INTRODUCTION: Postpartum pain is associated with impaired maternal recovery and may influence mother-infant bonding. METHODS: Participants who underwent a vaginal or cesarean delivery were assessed 24 h postpartum. Postpartum pain intensity was measured using the Verbal Numeric Score (VNS) (0-10) and classified as non-severe (<8) or severe pain (≥8). Maternal-infant bonding was evaluated using the Post-Partum Bonding Questionnaire (PBQ; 0-125), with a score > 5 defining impaired bonding. Demographic data included age, BMI, parity, education level, economic status, partnership, prior history of depression, familial history of depression, desire to breastfeed, epidural analgesia during labor, rooming in, and Edinburgh Postnatal Depression Scale (EPDS). Data were analyzed using 2 separate multivariable logistic regression models for vaginal and cesarean deliveries, where maximum postpartum pain was the independent variable and impaired postpartum bonding was the dependent variable and controlled for the other factors collected. RESULTS: Severe postpartum pain (VNS ≥ 8) showed no significant relationship with impaired bonding when controlling for confounding variables. In vaginal deliveries, there was an association between a history of depression and impaired bonding (Odds Ratio 2.2 [1.07-4.65], p = 0.04) and EPDS > 10 and impaired bonding (OR 11.5 [3.2-73.6], p < 0.001). For cesarean deliveries, rooming in with the baby had a protective effect (OR 11.5 [3.2-73.6], p < 0.001). CONCLUSIONS: Contrary to expectations, severe postpartum pain did not influence maternal-infant binding in the cohort of patients with vaginal and cesarean deliveries. Instead, factors such as maternal mental health and rooming-in practices appeared to exert more significant influence. CLINICAL TRIAL REGISTRATION: NCT05206552.

RESUMO

INTRODUCTION: There is no clear correlation between abnormal umbilical cord blood gas studies (UCGS) and adverse neonatal outcome in low-risk deliveries. We investigated the need for its routine use in low-risk deliveries. METHODS: We retrospectively compared maternal, neonatal, and obstetrical characteristics among low-risk deliveries (2014-2022) between "normal" and "abnormal" pH groups: A:normal pH ≥ 7.15; abnormal pH < 7.15; B: normal pH ≥ 7.15 and base excess (BE) > - 12 mmol/L; abnormal pH < 7.15 and BE ≤ We retrospectively compared 12 mmol/L; C: normal pH ≥ 7.1; abnormal pH < 7.1; D: normal pH > 7.1 and BE > - 12 mmol/L; abnormal pH < 7.1 and BE ≤ - 12 mmol/L. RESULTS: Of 14,338 deliveries, the rates of UCGS were: A-0.3% (n = 43); B-0.07% (n = 10); C-0.11% (n = 17); D-0.03% (n = 4). The primary outcome, composite adverse neonatal outcome (CANO) occurred in 178 neonates with normal UCGS (1.2%) and in only one case with UCGS (2.6%). The sensitivity and specificity of UCGS as a predictor of CANO were high (99.7-99.9%) and low (0.56-0.59%), respectively. CONCLUSION: UCGS were an uncommon finding in low-risk deliveries and its association with CANO was not clinically relevant. Consequently, its routine use should be considered.

RESUMO

BACKGROUND: The administration of antenatal corticosteroids (ACS) is standard practice for management of threatened preterm birth. Its benefit, especially in small for gestational age (SGA) late preterm, is unclear. OBJECTIVES: To evaluate the impact of ACS on perinatal outcome of late preterm SGA neonates. METHODS: We conducted a retrospective cohort study of all women carrying a singleton gestation who had late preterm delivery (34-36 gestational weeks) of SGA neonates at a single tertiary university-affiliated medical center (July 2012-December 2017). Exclusion criteria included termination of pregnancy, intrauterine fetal death, and birth weight ≥ 10th percentile. Outcomes were compared between ACS and non-ACS treatment prior to delivery. Neonatal composite outcome included neonatal intensive care unit (NICU) admission, respiratory distress syndrome, mechanical ventilation, and transient tachypnea. RESULTS: Overall, 228 women met inclusion criteria; 102 (44.7%) received ACS and 126 did not (55.3%). Median birth weight among the non-ACS group was significantly higher (1896.0 vs. 1755.5 grams P < 0.001). Rates of NICU and jaundice requiring phototherapy were higher among the ACS group (53.92% vs. 31.74%, P = 0.01; 12.74% vs. 5.55%, P = 0.05, respectively). Composite neonatal outcome was significantly higher among the ACS group (53.92% vs. 32.53%, odds ratio [OR] 2.42, 95% confidence interval [95%CI] 1.41-4.15, P = 0.01). After adjustment for potential confounders, this association remained significant (OR 2.15, 95%CI 1.23-3.78, P = 0.007). CONCLUSIONS: ACS given during pregnancy did not improve respiratory outcome for SGA late preterm neonates. ACS may be associated with a worse outcome.

RESUMO

PURPOSE: Obesity and preeclampsia share similar patho-mechanisms and can both affect placental pathology. We aimed to investigate pregnancy outcomes in correlation with placental pathology among pregnancies complicated by preeclampsia in three different maternal body mass index (BMI, kg/m2) groups. METHODS: In this retrospective cohort study, medical and pathological records of patients with preeclampsia and a singleton pregnancy delivered between 2008 and 2021 at a single tertiary medical center were reviewed. Study population was divided into three BMI groups: BMI < 22.6 kg/m2 (low BMI group), 22.7 ≤ BMI ≤ 28.0 kg/m2 (middle-range BMI group), and BMI > 28.0 kg/m2 (high BMI group). Data regarding maternal characteristics, neonatal outcomes, and placental histopathological lesions were compared. RESULTS: The study groups included a total of 295 patients diagnosed with preeclampsia-98, 99, and 98 in the low, middle-range, and high BMI groups respectively. Neonatal birth weight was significantly decreased in the low maternal BMI group compared to both middle and high BMI groups (p = 0.04) with a similar trend seen in placental weight (p = 0.03). Villous changes related to maternal malperfusion were more prevalent in the low and high BMI groups compared to middle-range BMI group (p < 0.01) and composite maternal vascular malperfusion lesions were also more prevalent in the groups of BMI extremities compared to the middle-range BMI group (p < 0.01). CONCLUSION: Maternal BMI might influence neonatal outcomes and placental pathology in pregnancies complicated by preeclampsia. Both extremes of BMI were associated with higher rates of placental maternal vascular malperfusion. Balanced BMI in women at risk for preeclampsia may reduce the incidence of placental lesions.

RESUMO

INTRODUCTION: Late fetal growth restriction (FGR) is associated with mild growth restriction and normal or mild abnormal doppler flows. The cerebroplacental ratio (CPR) has been demonstrated as more sensitive to hypoxia than its individual components in these fetuses. We hypothesized that abnormal CPR in late FGR is reflected in specific placental vascular malperfusion lesions. METHODS: Retrospective cohort study of late FGR newborns between 2012 and 2022 in a tertiary hospital. Overall, 361 cases were included: 104 with pathological CPR (study group), and 257 with normal doppler flows (control group). The primary outcome was a composite of maternal vascular malperfusion lesions (MVM) and fetal vascular malperfusion lesions (FVM). Secondary outcomes were macroscopic placental characteristics and various obstetrical and neonatal outcomes. RESULTS: The study group had lower birthweight compared with the normal CPR group (2063.5 ± 470.5 vs. 2351.6 ± 387.4 g. P < 0.0001), higher rates of composite adverse neonatal outcomes (34.2% vs. 22.5%, p < 0.0001), lower mean placental weight (318 ± 71.6 vs. 356.6 ± 76.5 g, p < 0.0001), as well as a higher prevalence of Vascular lesions of MVM (15.3% vs. 5.0%, p = 0.002), villous lesions of FVM (37.5% vs. 24.9%, p = 0.02), and composite FVM lesions (36.5% vs. 25.6%, p = 0.04). On multivariate regression analysis for MVM lesions and composite FVM lesions, abnormal CPR was found as an independent risk factor (aOR 2.17, 95% CI 1.63-4.19, and aOR 1.31, 95% CI 1.09-3.97, respectively). DISCUSSIONS: Abnormal CPR in late FGR is reflected in placental histopathologic vascular malperfusion lesions, and the incidence of these lesions is higher than in FGR placentas with normal CPR.

RESUMO

This retrospective study was conducted to determine if infants born prematurely despite prophylactic maternal progesterone treatment during pregnancy may still benefit from its adjunct properties and have decreased neonatal complications. 248 women treated with vaginal/intramuscular progesterone during pregnancy and 2519 controls who gave birth to a preterm newborn (24 + 0-36 + 6 gestational weeks) at a tertiary medical centre in 2012-2019. The primary outcome measure was neonatal infectious composite outcome. Secondary outcome measures were other maternal and neonatal complications. Compared to controls, the study group was characterised by lower gestational age at birth (35.0 ± 2.66 vs. 36.0 ± 2.23 weeks, p < .001), lower birth weight (2294 vs. 2485 g, p < .001), higher rates of neonatal infectious composite outcome (27.82 vs. 21.36%, p = 0.024), NICU admission, periventricular leukomalacia, and mechanical ventilation. The higher neonatal infectious composite outcome is likely associated with the lower gestational age at birth in this high-risk group and not the progesterone treatment per se.IMPACT STATEMENTWhat is already known on this subject? Several randomised controlled trials have shown that progesterone administration in pregnancy significantly reduced the rate and complications of preterm birth. A recent study reported that vaginal administration of progesterone during pregnancy was more effective than intramuscular administration in decreasing vaginal group B Streptococcus (GBS) colonisation. This finding raises the question of whether progesterone treatment may have additional benefits besides preventing preterm birth and may reduce neonatal complication rate in preterm infants.What do the results of this study add? This is the first study examining the impact of gestational progesterone exposure on outcomes of preterm infants. The primary objective was a composite measure of infectious neonatal outcomes. Newborns who had progesterone exposure on average had lower gestational age, lower birth weight and higher neonatal infectious composite outcome. The significant difference is explained by lower gestational age.What are the implications of these findings for clinical practice and/or further research? Progesterone is widely used to prevent preterm birth, and may have important additive effects even when prematurity is not avoided. Although the findings did not support our initial hypothesis, they warrant further examination with larger cohorts.

RESUMO

BACKGROUND: The optimal mode of delivery in cases of fetal congenital heart disease (CHD) is not established. The few relevant studies did not address operative vaginal delivery. The aim of this study was to assess the impact of fetal CHD on mode of delivery during a trial of labor, and to secondarily describe some obstetric complications. METHODS: The database of a tertiary medical center was searched for women who gave birth to a singleton, liveborn neonate in 2015-2018. Mode of delivery was compared between women carrying a fetus with known CHD and women with a healthy fetus matched 1:5 for maternal age, parity, body mass index, and gestational age. RESULTS: The cohort included 616 women, 105 in the CHD group and 511 in the control group. The rate of operative vaginal delivery was significantly higher in the CHD group (18.09% vs 9.78%, OR 2.03, 95% CI 1.13-3.63, p = 0.01); the difference remained significant after adjustment for nulliparity and gestational age at delivery (aOR 2.58, 95% CI 1.36-4.9, p < 0.01). There was no difference between the CHD and control group in rate of intrapartum cesarean delivery (9.52% vs 10.76%, respectively, OR 0.97, 95% CI 0.47-1.98, p = 0.93). The most common indication for operative vaginal delivery was non-reassuring fetal heart rate (78.94% vs 64%, respectively). Median birth weight percentile was significantly lower in the CHD group (45th vs 53rd percentile, p = 0.04). CONCLUSIONS: Our findings suggest that operative vaginal delivery, performed mostly because of non-reassuring fetal heart rate, is more common in pregnancies complicated by a prenatal diagnosis of CHD than non-anomalous pregnancies.

RESUMO

BACKGROUND: The COVID-19 pandemic is an ongoing global healthcare crisis that negatively affects pregnant women. Although patients with an acute infection during pregnancy have been widely studied, information regarding labor and delivery while infected is sparse. The aim of the study was to ascertain maternal, obstetrical, and perinatal outcomes of women who gave birth while infected with SARS-CoV-2. METHODS: Patients diagnosed with COVID-19 during pregnancy at a tertiary medical center in 4/20-2/21 were identified by a retrospective database search. Those with an active intrapartum SARS-CoV-2 infection were compared with those who recovered at least 10 days before labor and delivery. RESULTS: Of the 176 women included in the study, 84 had a SARS-CoV-2 infection at the time of delivery and 92 had recovered from the infection. There was no statistically significant between-group difference in mean gestational age at delivery (39 weeks for both, p = 0.71) and overall rate of cesarean delivery (26.2% vs 17.4%, respectively, p = 0.35) or non-elective cesarean delivery (10.71% vs 4.34%, respectively, p = 0.48). In the active-infection group, the rate of severe disease was 2.4%, and of critical disease (with intensive care unit admission, mechanical ventilation, and ECMO), 3.6%, compared to zero for both in the recovered group. No differences were found between the groups in adverse perinatal outcomes. CONCLUSION: Delivery is safe and feasible in women with active SARS-CoV-2 infection. Nevertheless, we found a non-significant trend for more severe disease and for cesarean delivery and urgent cesarean delivery (for COVID-19-related indications) in women with an intrapartum SARS-CoV-2 infection.

RESUMO

BACKGROUND: Preeclampsia is a multisystem disorder characterized by an abnormal vascular response to placentation associated with increased systemic vascular resistance. As liver involvement is one of the main clinical features of preeclampsia, we sought to determine if there is an association between chronic liver diseases and preeclampsia. METHODS: A retrospective matched case-control analysis was conducted in a tertiary medical center. Three hundred eleven (311) pregnant women with preexisting chronic liver disease (study group), including viral and autoimmune hepatitis, non-alcoholic fatty liver, Wilson disease, and cirrhosis, were match for age, parity, and number of fetuses to 933 healthy pregnant women (control group). The primary outcome measure was the incidence of preeclampsia in each group. Secondary outcome measures were obstetrical and neonatal complications. Confounders found to be significant on univariate analysis were evaluated using logistic regression models, and odds ratios (OR) and confidence intervals (CI) were calculated. RESULTS: Preeclampsia was diagnosed in 28 women (9.0%) in the study group and 33 women (3.54%) in the control group (p < 0.001). On multivariate analysis adjusted for maternal age, parity, previous preeclampsia, chronic hypertension, gestational diabetes mellitus, pregestational diabetes mellitus, antiphospholipid syndrome, and mode of conception, chronic liver disease was found to be an independent risk factor for preeclampsia (aOR 2.631, 95% CI 1.518-4.561). Although there was no difference in the gestational week at delivery between the groups (38.6 ± 2.13 vs. 38.8 ± 2.17 for study and control group, respectively, p = 0.410), the study group had a lower mean neonatal birthweight (3088 ± 551 vs. 3182 ± 566 g, p = 0.011). There were no between-group differences in the other parameters evaluated. CONCLUSION: In our study, preexisting chronic liver disease was associated with a 2.6-fold increased risk of preeclampsia.

RESUMO

The course of COVID-19 has been shown to be worse in pregnant women compared with their non-pregnant counterparts. The aim of this study is to share our experience treating pregnant women with COVID-19 and to establish a cohort for future studies of the long-term effects of the disease. We reviewed medical records of all SARS-CoV-2-positive pregnant women who were treated at our hospital for any reason, be it COVID-19 related or not, between April 2020 and February 2021. We extracted data regarding medical history, course of pregnancy, delivery, and neonatal outcomes. A total of 193 SARS-CoV-2-positive pregnant women were treated at our establishment during the study period, half of which were asymptomatic. Sixteen were hospitalized for COVID-19 symptoms, the most common being fatigue/malaise (58%) and cough (48%). Three women required mechanical ventilation and extracorporeal membrane oxygenation treatment. One hundred forty-four SARS-CoV-2-positive women were delivered during the study period. Of them, 24 (17%) underwent induction of labor, and four (17%) were due to symptomatic COVID-19. One hundred fifteen (80%) experienced vaginal delivery, and 29 (20%) underwent cesarean delivery. Neonatal outcomes were favorable; only 2% of 5-min Apgar scores were < 7, and all umbilical cord pH levels were > 7.1. Six infants tested positive for SARS-CoV-2; they were all asymptomatic, and none required treatment for viral infection. COVID-19 during pregnancy is a disease with potential substantial adverse maternal and neonatal outcomes. There is still much unknown regarding the long-term effects of the disease on parturients and their offspring.

RESUMO

Background: Mobile medical devices for self-patient use are a rapidly evolving section of telehealth. We examined the INSTINCT® ultrasound system, a portable, self-operated ultrasound device attached to a commercial smartphone for remote fetal assessment. We aimed to evaluate whether it is feasible to use remote fetal assessment during pregnancy. Materials and Methods: This is an observational noninterventional trial. We included women with a singleton fetus at 14 + 0 to 39 + 6 gestational weeks. Each participant received the device for a self-use period of 7-14 days and was instructed to perform one to three scans a day. Participants completed a self-assessment questionnaire to evaluate safety and usability (i.e., user experience and satisfaction). Each scan was evaluated for fetal heart activity, amniotic fluid volume, fetal tone, fetal body, and breathing movements. Results: One hundred women, completing 1,360 self scans, used the device for 8.1 ± 1.5 days, performing an average of 13.6 ± 6.2 scans each. There were no device-related serious adverse events. Success in detection was 95.3% for fetal heart activity, 88.3% for body movements, 69.4% for tone, 92.2% for normal amniotic fluid volume, and 23.8% for breathing movements. Interobserver agreement was 94.4% for fetal heart rate activity, 85.9% for body movements, 69.5% for fetal tone, 86.9% for amniotic fluid volume, and 94.0% for breathing movements. Self-assessed user experience was rated at 4.4/5, whereas device satisfaction was rated at 3.9/5. Conclusion: The INSTINCT ultrasound system is a feasible solution for remote sonographic fetal assessment. Further studies are needed to assess its role and impact in telehealth antenatal care and fetal surveillance.

RESUMO

In this prospective study, we evaluated postpartum voiding dysfunction stratified by mode of delivery - vaginal delivery versus elective caesarean delivery (CD). We recruited nulliparous women carrying singleton gestation at term admitted to delivery room or elective CD. Pre-labour voiding function was assessed by recording the post-voiding residual volume (PVRV) using a bladder scan. PVRV evaluation was repeated at least 12 hours following delivery and before discharge. PVRVs were considered abnormal if ≥150 mL. PVRVs were compared between vaginal and CD. Overall, 54 women were included. Of them, 34 (63%) delivered vaginally and 20 (37%) had an elective CD. Postpartum mean PVRVs were significantly higher compared to pre-labour PVRVs (215 vs. 133 mL, p<.001). Abnormal postpartum PVRV was significantly higher in vaginal delivery compared to CD (73.5% vs. 45%, p<.05). In conclusion, delivery adversely affects voiding function. Vaginal delivery is associated with more severe voiding dysfunction compared to elective CD.Impact StatementWhat is already known on this subject? Delivery is associated with voiding dysfunction. While most studies on postpartum voiding dysfunction were related to vaginal delivery, little is known on the effect of mode of delivery (vaginal versus caesarean delivery (CD)) on voiding dysfunction.What the results of this study add? In this study, we found that postpartum post-voiding residual volume is significantly higher than the pre-labour PVRV in women delivered vaginally. In addition, postpartum PVRV was significantly higher in women delivered vaginally compared to elective CD.What the implications are of these findings for clinical practice and/or further research? This study implicates that women with vaginal delivery are more prone to voiding dysfunction compared to elective CD. However, larger observational studies are warranted to confirm these results and evaluate whether this difference still exists beyond the post-partum period.

RESUMO

OBJECTIVE: To evaluate outcomes of fetal reduction in twin pregnancy. SEARCH STRATEGY: PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and Google Scholar were searched from 1980 through December 2020. SELECTION CRITERIA: Prospective or retrospective studies of pregnant women with twin gestations who had a transabdominal reduction of twin to singleton pregnancy with a comparison group of ongoing twin gestations. DATA COLLECTION AND ANALYSIS: Outcomes were meta-analyzed only if reported in at least three studies. MAIN RESULTS: Six studies with a pooled sample of 2867 women with a twin pregnancy of whom 624 underwent 2-to-1 reduction and 2243 did not. In the fetal reduction group, the odds of preterm birth before 34 and 37 weeks of pregnancy were lower by 36% (odds ratio [OR] 0.64, 95% confidence interval [CI] 0.48-0.86, P < 0.003) and 77% (OR 0.23, 95% CI 0.12-0.44, P < 0.001), respectively, than in the control group, and the odds of hypertensive disorders and cesarean delivery were lower by 75% (OR 0.25, 95% CI 0.15-0.43, P < 0.001) and 65% (OR 0.35, 95% CI 0.20-0.62, P < 0.001), respectively. CONCLUSION: Twin reduction to singleton pregnancy decreased the possibility of preterm birth, hypertensive disorders in pregnancy and cesarean delivery. Sufficiently powered prospective studies are needed to support these findings.

BACKGROUND: In utero Cytomegalovirus (CMV) vertical transmission occurs predominantly during primary maternal infection. There are no known non-invasive methods for diagnosis of fetal infection before delivery, however some risk factors have been suggested. We aimed to evaluate the association between maternal CMV urinary excretion and congenital CMV infection. METHODS: A retrospective cohort study of all women who were diagnosed with primary CMV infection during pregnancy in a single university affiliated tertiary medical center, between 2012 and 2016. We examined congenital CMV infection and disease rates among infants born to women with and without CMV urinary excretion. RESULTS: Overall, 126 women were included, 77 in the positive urinary excretion group, and 49 in the negative urinary excretion group. There was no difference in maternal symptoms between the groups. We found no difference in congenital CMV infection and disease rates between infants born to women with and without urinary excretion of CMV (congenital infection rate 37.1% vs. 24.4%, p = 0.209, congenital disease rate of 18.2% vs. 22.4%, p = 0.648). Women with positive urinary CMV excretion had lower IgG avidity values (36.7% vs 54.6%, p = 0.007), with no additional difference in serology pattern. Compared to asymptomatic women, those with CMV related symptoms did not have significantly higher rates of urinary excretion of CMV (70% vs. 60.5%, p = 0.38) or congenital infection rates (40.7% vs. 31.2%, p = 0.48). CONCLUSION: Among infants of women with primary CMV infection in pregnancy, we did not find an association between urinary excretion of CMV and congenital CMV infection.

RESUMO

Social behaviors are mediated by the activity of highly complex neuronal networks, the function of which is shaped by their transcriptomic and proteomic content. Contemporary advances in neurogenetics, genomics, and tools for automated behavior analysis make it possible to functionally connect the transcriptome profile of candidate neurons to their role in regulating behavior. In this study we used Drosophila melanogaster to explore the molecular signature of neurons expressing receptor for neuropeptide F (NPF), the fly homolog of neuropeptide Y (NPY). By comparing the transcription profile of NPFR neurons to those of nine other populations of neurons, we discovered that NPFR neurons exhibit a unique transcriptome, enriched with receptors for various neuropeptides and neuromodulators, as well as with genes known to regulate behavioral processes, such as learning and memory. By manipulating RNA editing and protein ubiquitination programs specifically in NPFR neurons, we demonstrate that the proper expression of their unique transcriptome and proteome is required to suppress male courtship and certain features of social group interaction. Our results highlight the importance of transcriptome and proteome diversity in the regulation of complex behaviors and pave the path for future dissection of the spatiotemporal regulation of genes within highly complex tissues, such as the brain.

RESUMO

BACKGROUND: We aimed to evaluate the association of isolated fetal microcephaly measured by ultrasound prior to delivery at term with mode of delivery and perinatal outcome. METHODS: A single-center retrospective study was conducted in 2012-2016. Fetal microcephaly was defined as head circumference > 2 standard deviations of the mean for gestational age and sex. We compared the obstetric, delivery, and outcome parameters of women in whom ultrasound performed up to 10 days prior to term delivery showed isolated fetal microcephaly (study group) or normal head circumference (reference group). Exclusion criteria were intrauterine fetal death, birthweight below the 10th percentile, and antepartum cesarean delivery for any indication. RESULTS: Of 3677 women included in the study, 26 (0.7%) had a late ultrasound finding of isolated fetal microcephaly. Baseline characteristics were similar in the two groups except for estimated fetal weight based on abdominal circumference and biparietal diameter, which was lower in the microcephaly group (3209.8 ± 557.6 vs. 2685.8 ± 420.8 g, p < .001). There was no significant between-group difference in rate of vaginal operative deliveries (11.7% vs 14.8%, respectively, p = 0.372). The study group had no intrapartum cesarean deliveries compared to 6.3% of the reference group (NS). Compared to controls, neonates in the study group were smaller (3323.2 ± 432.2 vs. 2957.0 ± 330.4 g, p < .001), with lower birthweight percentile (60.5 ± 26.5 vs. 33.6 ± 21.5%, p < .001) and were more often males (48.2 vs. 90.0%, p < .001). No significant differences were noted in perinatal outcomes between the groups, including admission to neonatal intensive care unit, intraventricular hemorrhage, 5-min Apgar score < 7, asphyxia, seizures, and sepsis. CONCLUSIONS: Isolated microcephaly in term fetuses is not advantageous for a vaginal delivery, nor does it does not pose a greater than normal risk of adverse perinatal outcome.

RESUMO

BACKGROUND: There are still some controversies regarding the risks and benefits of fetal reduction from twins to singletons. We aimed to evaluate if fetal reduction from twins to singleton improves pregnancy outcome. METHODS: Retrospective analysis of all dichorionic-diamniotic twin pregnancies, who underwent fetal reduction. Pregnancy outcome was compared to ongoing, non-reduced, dichorionic-diamniotic gestations. Primary outcome was preterm birth prior to 37 gestational weeks. Secondary outcomes included: preterm birth prior to 34 gestational weeks, gestational age at delivery, birthweight, small for gestational age, hypertensive disorders, gestational diabetes and stillbirth. RESULTS: Ninety-eight reduced pregnancies were compared with 222 ongoing twins. Preterm birth < 37 gestational weeks (39.6% vs. 57.6%, p < 0.001) was significantly lower in the reduced group compared to the ongoing twins' group. A multivariate analysis, controlling for parity and mode of conception, demonstrated that fetal reduction independently and significantly reduced the risk for prematurity (aOR 0.495, 95% CI -0.299-0.819). Subgroup analysis, similarly adjusted demonstrated lower rates of preterm delivery in those undergoing elective reduction (aOR = 0.206, 95% CI 0.065-0.651), reduction due to fetal anomalies (aOR = 0.522, 95% CI 0.295-0.926) and 1st trimester reduction (aOR = 0.297, 95% Cl 0.131-0.674) all compared to ongoing twins. A Kaplan-Meier survival curve showed a significant proportion of non-delivered women at each gestational week in the reduced group compared to non-reduced twins, after 29 gestational weeks. CONCLUSIONS: Fetal reduction from twins to singleton reduces the risk of preterm birth < 37 gestational weeks, but not for more severe maternal and perinatal complications.

RESUMO

INTRODUCTION: The safety of neuro-axial anaesthesia (epidural/spinal) at labour of women with partial factor XI (FXI) deficiency is uncertain. Although FXI deficiency is frequent in Ashkenazi Jews, it is not routinely measured before labour. Our institute serves a large Ashkenazi population. We assumed that 10% of them have undiagnosed FXI deficiency. AIM: Assess the incidence, bleeding tendency and coagulation status among Jewish Ashkenazi women with FXI deficiency that underwent neuro-axial anaesthesia at delivery. METHODS: Jewish Ashkenazi women who underwent neuro-axial anaesthesia at labour completed the SSC ISTH bleeding assessment tool (BAT) and had blood drawn for coagulation tests, FXI and thrombin generation after labour. Estimation for 10 years was calculated from the 1-year sample. RESULTS: We recruited 261 women during 12 months. Among them, 39 (15%) had FXI deficiency (<70%) with median FXI levels of 63% (range: 33%-70%). Around 50% of them underwent amniocentesis in the current pregnancy and prior neuro-axial anaesthesia with no bleeding complications. BAT score and thrombin generation did not differ between women regardless of FXI status. aPTT was longer in women with partial FXI deficiency (median - 28.6 sec vs 26.3 sec, P < .001, Table 2), although within the normal range in all women. No bleeding complications after neuro-axial anaesthesia at delivery were reported in our centre in the last decade though, and according to our estimation, at least 2150 women had partial FXI deficiency. CONCLUSIONS: A significant number of Jewish Ashkenazi women with undiagnosed partial FXI deficiency undergo neuro-axial anaesthesia at labour without bleeding complications.

RESUMO

BACKGROUND: Spinal morphine provides the optimal treatment for post-cesarean analgesia, despite frequent nausea and vomiting. We investigated the incidence of nausea and vomiting 24 hours after cesarean delivery in women receiving intrathecal morphine 100 µcg and intravenous prophylactic dexamethasone and ondansetron. METHODS: In a prospective, observational, Institutional Review Board (IRB) approved study of women undergoing cesarean delivery according to a standardized anesthetic protocol, the subjects were approached preoperatively and underwent standardized interviews regarding prior anesthesia experience and history of postoperative nausea and vomiting. In the post anesthesia care unit and 24 hours postoperatively, the women were interviewed regarding the incidence of nausea and vomiting, Women with and without nausea at 24 hours were compared for potential associated risk factors. RESULTS: Among 201 women recruited, 29 (14.5%) had nausea and 7 (3.5%) vomited in the postoperative care unit. During the first 24 hours, 36 (17.9%) had experienced nausea and 19 (9.5%) had vomited when interviewed at the 24-hours postoperatively. Women who had nausea 24 hours postoperatively were more likely to have nausea in the post anesthesia care unit than women without nausea during 24 hours after cesarean delivery (41.7% versus 1.2%, p<0.001). We did not find preoperative risk factors for postoperative nausea and vomiting. CONCLUSIONS: We report that almost 20% of the women managed with prophylactic dual therapy of ondansetron and dexamethasone had nausea during the 24 hours after administration of low dose intrathecal morphine. Our findings suggested that women who experience nausea or vomiting in the immediate postoperative period are at increased risk of nausea and vomiting in the 24-hour postoperative period.
