RESUMO

PURPOSE: To assess the prevalence, microbial profile, and clinical risk factors of maternal bacteremia associated with intrapartum fever (IPF). METHODS: A retrospective cohort study, in a single tertiary university-affiliated medical center between 2012 and 2018. Demographic and labor characteristics of women, who delivered at term (37+0/7-41+6/7) and developed bacteremia following IPF were compared to a control group of women with IPF but without bacteremia. RESULTS: During the study period there were 86,590 deliveries in our center. Of them, 2074 women (2.4%) were diagnosed with IPF, of them, for 2052 women (98.93%) the blood maternal cultures were available. In 26 patients (1.25%) maternal bacteremia was diagnosed. A lower rate of epidural anesthesia (84.6% vs 95.9%, p = 0.02) and a higher rate of antibiotics prophylaxis treatment prior to the onset of fever (30.8%.vs 12.1%, p = 0.006) were observed in patients who developed maternal bacteremia in comparison to those who have not. Maternal hyperpyrexia developed after initiation of antibiotics or without epidural anesthesia remained significantly associated with maternal bacteremia after applying a multivariate analysis, (Odds Ratio 3.14 95% CI 1.27-7.14, p = 0.009; 4.76 95% CI 1.35-12.5, p = 0.006; respectively). CONCLUSION: Maternal fever developing after initiation of antibiotics or without epidural is associated with maternal bacteremia.

RESUMO

OBJECTIVE: We aimed at assessing the association between meconium-stained amniotic fluid (MSAF) and adverse maternal and neonatal outcomes in early-term versus late-term pregnancies. STUDY DESIGN: Early-term pregnancies (37-39 weeks of gestation) presented with MSAF were compared with late-term (40-42 weeks of gestation) pregnancies with MSAF. The groups were compared with respect to background characteristics, maternal outcomes, and neonatal outcomes. The composite neonatal outcome was the primary outcome of the study, and secondary outcomes included maternal and neonatal outcomes. RESULTS: The early-term group comprised 239 women, compared with 362 women in the late-term group. The primary outcome did not differ between groups. We found a higher prevalence of gestational diabetes (8.37 vs. 3%, p < 0.05), a shorter second stage of labor (45.61 ± 54.67 vs. 65.82 ± 62.99 minutes, p < 0.05), and a longer hospital stay (2.84 ± 2.21 vs. 2.53 ± 1.26 days, p < 0.05) in the early-term group. Other maternal and neonatal characteristics and outcomes were not significantly different between the two groups. CONCLUSION: In term pregnancies complicated by MSAF, adverse neonatal and maternal delivery outcomes are equivalent, regardless of gestational age, and therefore, any term pregnancy complicated by MSAF should be considered high risk and managed appropriately. KEY POINTS: · In term pregnancies complicated by MSAF, adverse neonatal and maternal delivery outcomes are equivalent, regardless of gestational age.. · Any term pregnancy complicated by MSAF should be considered high risk and managed appropriately.. · Deliveries presented with MSAF are typically considered to be high risk and require close fetal surveillance by a certified team with resuscitation skills.. · Our study may help to reduce the need for a close fetal surveillance and delivery interventions if MSAF is not identified as a risk factor for adverse outcomes in late-term pregnancies..

RESUMO

OBJECTIVES: Data on the association between Bell's palsy (BP) and pregnancy is scarce and there is an ongoing debate regarding the association of BP and pregnancy. MAIN OUTCOME MEASURES: We aimed to investigate the prevalence of BP among pregnant patients and determine the frequency of pregnant women in BP cohorts and vice versa, assess which term of the pregnancy and peripartum bears a higher risk for BP occurrence, and determine the prevalence of maternal comorbidities associated with BP during pregnancy. DESIGN: Meta analysis. SETTINGS: Screening standard articles and extracting data from Ovid MEDLINE (1960-2021), Embase (1960-2021), and Web of Science (1960-2021). All study types were included except for case reports. MEASURES: Data were pooled by means of both fixed and random-effects models. RESULTS: The search strategy identified 147 records. Twenty-five of the studies that met our inclusion criteria described 809 pregnant patients with BP in a total of 11,813 BP patients and they were included in the meta-analysis. The incidence of BP among the pregnant patients was 0.05%; The incidence of pregnant patients among all BP patients was 6.62%. Most of the BP occurrences were during the third trimester (68.82%). The pooled incidence of gestational diabetes mellitus; hypertension; pre-eclampsia/eclampsia and fetal complications among the pregnant patients with BP was 6.3%, 13.97%, 9.54%, and 6.74%, respectively. CONCLUSIONS: This meta-analysis revealed a low incidence of BP during pregnancy. A Higher proportion occurred during the third trimester. The association of BP and pregnancy warrants further exploration.

RESUMO

Natural iron-rich mineral water (IRMW) is a supplement with a higher iron bioavailability than oral iron supplement tablets. Five (4%) of 116 women who consumed IRMW starting from 16 weeks of gestation were diagnosed as having isolated foetal echogenic bowel at a single community maternity clinic between 2012 and 2015. The workup of all the women was otherwise negative. Four women taking IRMW were re-checked after discontinuation of the supplement and had a normal-appearing foetal bowel. Our observations suggest that isolated echogenic bowel may be related to the consumption of IRMW, possibly due to the high absorption of iron, leading to the coating of the internal wall of the foetal bowel and subsequent appearance of an echogenic bowel. Although this finding appears free of harmful ramifications, its possible sonographic effects on the appearance of the foetal bowel should be considered in light of the increasing popularity of IRMW use.IMPACT STATEMENTWhat is already known on this subject? IRMW is a highly absorbed iron supplement. The differential diagnosis for foetal echogenic bowel is broad and requires thorough investigation. Iron is secreted through the maternal blood to the amniotic fluid, which is swallowed by the foetus, reaching its bowel.What do the results of this study add? IRMW consumption is a possible aetiology of an isolated foetal echogenic bowel in the second half of pregnancy, conveying no risk of foetal morbidity or mortality.What are the implications of these findings for clinical practice and/or further research? In light of the increasing popularity of IRMW, we believe that it is important to increase the level of awareness of the possible effects of its intake on the sonographic appearance of the foetal bowel.

RESUMO

The 10 K is a large-scale prospective longitudinal cohort and biobank that was established in Israel. The primary aims of the study include development of prediction models for disease onset and progression and identification of novel molecular markers with a diagnostic, prognostic and therapeutic value. The recruitment was initiated in 2018 and is expected to complete in 2021. Between 28/01/2019 and 13/12/2020, 4,629 from the expected 10,000 participants were recruited (46 %). Follow-up visits are scheduled every year for a total of 25 years. The cohort includes individuals between the ages of 40 and 70 years. Predefined medical conditions were determined as exclusions. Information collected at baseline includes medical history, lifestyle and nutritional habits, vital signs, anthropometrics, blood tests results, Electrocardiography, Ankle-brachial pressure index (ABI), liver US and Dual-energy X-ray absorptiometry (DXA) tests. Molecular profiling includes transcriptome, proteome, gut and oral microbiome, metabolome and immune system profiling. Continuous measurements include glucose levels using a continuous glucose monitoring device for 2 weeks and sleep monitoring by a home sleep apnea test device for 3 nights. Blood and stool samples are collected and stored at - 80 °C in a storage facility for future research. Linkage is being established with national disease registries.

RESUMO

PURPOSE: Pregnancies conceived by in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) are associated with an increased incidence of obstetrical and neonatal complications. With the growing rate of male factor infertility, which is unique by not involving the maternal milieu, we aimed to assess whether obstetrical outcomes differed between IVF/ICSI pregnancies due to male factor infertility and those not due to male factor infertility. METHODS: A retrospective cohort study of women receiving IVF/ICSI treatments at a single hospital over a five-year period was involved in the study. Inclusion criteria were women with a viable pregnancy that delivered at the same hospital. Pregnancies were divided into male factor only related and non-male factor-related infertility. The groups were compared for several maternal and neonatal complications. RESULTS: In total, 225 patients met the study criteria, with 94 and 131 pregnancies belonging to the male factor and non-male factor groups, respectively. Demographic and clinical characteristics were comparable, except for younger maternal age and higher incidence of twin pregnancies in the male factor group. A sub-analysis for singleton pregnancies revealed a less likelihood of cesarean delivery, preterm birth, and male gender offspring in the male factor group (p < 0.05). These differences were not observed in the sub-analysis for twin pregnancies. Other outcome measures were similar in both groups, both for singleton and twin pregnancies. CONCLUSION: Singleton IVF pregnancies due to male factor infertility are associated with a reduced incidence of some adverse outcomes, likely due to lack of underlying maternal medical conditions or laboratory conditions related to ICSI. Our findings require validation by further studies on larger samples.

RESUMO

PURPOSE: Thrombocytopenia is the second most common hematological disorder in pregnancy and complicates approximately 10% of all pregnancies. The data regarding the association of mild thrombocytopenia in women undergoing cesarean section and risk of bleeding or bleeding-related complications are scarce. Thus, the aim of the current study was to assess the association of mild thrombocytopenia with hemorrhage-related morbidities, among patients undergoing elective cesarean section. METHODS: We performed a retrospective cohort study, in a single tertiary university-affiliated medical center, between 1 January 2012 and 31 May 2019. Medical charts of women who underwent elective cesarean section at term (37+0/7-41 + 6/7 weeks of gestations) were retrieved and analyzed. We compared women with mild thrombocytopenia (platelet count of 100-149 × 103/µL) to women with normal platelet count (150-450 × 103/µL). The primary outcome was the need for red blood cell transfusion during the index admission. A secondary outcome was severe bleeding not requiring blood transfusion defined as postpartum hemoglobin decline of ≥ 3 g/dL as compared to the prepartum levels. RESULTS: During the study period, 1577 women were included in the final analysis, of them 396 (25.11%) had mild thrombocytopenia prior to delivery. As compared to the control group, women with mild thrombocytopenia had higher rates of blood transfusion (3.79 vs. 1.52%, p = 0.01), and had a significant decline in hemoglobin levels. In a multivariable logistic regression model, mild thrombocytopenia was independently associated with blood transfusion with adjusted OR of 2.34 (95% CI 1.10-4.96, p = 0.03). CONCLUSION: Preoperative mild thrombocytopenia is associated with an increased risk of blood loss and blood transfusion in women undergoing elective CS. More studies are required to assess those observations in context of urgent cesarean sections and whether any preventive measures can reduce the risk for bleeding.

RESUMO

OBJECTIVE: Determining the efficacy of performance of a second external cephalic version (ECV) following successful first ECV with subsequent spontaneous reinversion to breech presentation in reducing the rate of cesarean delivery (CD). METHODS: Data were reviewed on healthy women with fetuses in breech presentation who underwent a first ECV after 36 weeks. Routine ultrasound study was performed at 39-week gestation, and a repeat ECV procedure was performed if the fetus had reverted to non-cephalic presentation. Obstetrical outcome measures were compared between women who underwent one successful ECV between 36- and 41-week gestation in which the fetus remained in cephalic presentation until labor and those who underwent a successful first ECV after which the fetus returned to breech and a second ECV was performed. The primary outcome was the rate of secondary CD during vaginal delivery in cephalic presentation; rate of successful second ECV was the secondary outcome. RESULTS: Overall 250 women underwent one ECV attempt of which 169 (67%) were successful. Of them 28 reverted to breech presentation, all women underwent two attempts of which 21 (76%) were successful. A second successful ECV attempt was associated with a 33% incidence of a CD vs. 2.8% after one successful ECV in which the fetus remained in cephalic presentation. CONCLUSION: A second ECV after a successful first ECV with subsequent spontaneous reversion to breech presentation can be expected to be successful in 76% of cases but lead to CD in 33% of cases. Our findings can be used to support patient counseling and decision-making before second ECV attempt.

RESUMO

BACKGROUND: The optimal interpregnancy interval after a single pregnancy loss is controversial. It is common obstetrical practice to recommend that women who have had a miscarriage in the first trimester of pregnancy should wait for 1 or more menstrual cycles before attempting to conceive again. OBJECTIVE: This study aimed to assess whether conception before the first menstrual period after a spontaneous pregnancy loss is associated with a risk of repeat miscarriage or adverse perinatal outcomes. STUDY DESIGN: This retrospective cohort study included 107 women who had a spontaneous miscarriage in the first trimester of pregnancy followed by a subsequent pregnancy with an interpregnancy interval of <12 weeks. All miscarriages had ended in either spontaneous expulsion of the products of conception or medical or surgical evacuation of the uterus. The perinatal outcome measures of 57 women who conceived after the first menstrual period following a spontaneous miscarriage were compared with perinatal outcome measures of 50 women who conceived before the first menstrual period following a spontaneous miscarriage. The primary outcome was rate of pregnancy loss, and the secondary outcomes were gestational age at delivery and birthweight. RESULTS: The rate of recurrent miscarriage was 10.4% for women who conceived before the first menstrual period following a spontaneous miscarriage and 15.8% for those who conceived after (P=.604). There were no differences in the gestational age at delivery (38.9 vs 38.7 weeks; P=.66) or the birthweight (3347±173 vs 3412±156 g; P=.5) between the 2 groups. Other outcomes, such as mode of delivery and 5-minute Apgar score, were also similar for both groups. A multiple logistic regression analysis confirmed that conception before the first menstrual period following a spontaneous miscarriage was not associated with a higher incidence of subsequent miscarriage (odds ratio, 1.74; P=.46) or any other untoward outcome. CONCLUSION: Conception shortly after a spontaneous miscarriage without waiting for at least the first postmiscarriage menstrual period is not associated with adverse maternal or neonatal outcomes compared with those of women with similar interpregnancy intervals who conceived after their next menstrual period.

RESUMO

Gynecologic cancer requires personalized care to improve outcomes. Large language models (LLMs) hold the potential to provide intelligent question-answering with reliable information about medical queries in clear and plain English, which can be understood by both healthcare providers and patients. We aimed to evaluate two freely available LLMs (ChatGPT and Google's Bard) in answering questions regarding the management of gynecologic cancer. The LLMs' performances were evaluated by developing a set questions that addressed common gynecologic oncologic findings from a patient's perspective and more complex questions to elicit recommendations from a clinician's perspective. Each question was presented to the LLM interface, and the responses generated by the artificial intelligence (AI) model were recorded. The responses were assessed based on the adherence to the National Comprehensive Cancer Network and European Society of Gynecological Oncology guidelines. This evaluation aimed to determine the accuracy and appropriateness of the information provided by LLMs. We showed that the models provided largely appropriate responses to questions regarding common cervical cancer screening tests and BRCA-related questions. Less useful answers were received to complex and controversial gynecologic oncology cases, as assessed by reviewing the common guidelines. ChatGPT and Bard lacked knowledge of regional guideline variations, However, it provided practical and multifaceted advice to patients and caregivers regarding the next steps of management and follow up. We conclude that LLMs may have a role as an adjunct informational tool to improve outcomes.

RESUMO

The relation between grand multiparity and poor pregnancy outcome, especially postpartum hemorrhage and blood transfusion, has displayed inconsistent findings. Some studies have identified an increased maternal and neonatal morbidity, but the more recent literature is less clear about the risks. The objective of the study is to determine the association of grand multiparity with postpartum blood transfusion. We conducted a retrospective cohort study in a single tertiary university-affiliated medical center between 2011 and 2019. All women were categorized into one of three groups based on the number of previous deliveries: (a) nulliparous (no previous delivery), (b) multiparous (1-4 previous deliveries), and (c) grand multiparous (≥ 5 previous deliveries). We compared the demographic, clinical, and pregnancy outcomes of the study groups. The primary outcome was the need for red blood cell transfusion during the index admission. During the study period, there were 87,343 deliveries in our center. Among the study population, 36,777 (42.1%) were nulliparous, 49,072 (56.1%) were multipara, and 1494 (1.7%) were grand multiparous. Overall, 1602 women (1.8%) were treated with RBC transfusion. Cesarean delivery, macrosomia, preterm delivery, multiple gestations, antenatal anemia, thrombocytopenia, intrauterine fetal death (IUFD), and prolonged second or third stage of labor were more prevalent among women who were treated with RBC transfusion. After controlling for potential confounders, including maternal age, preterm delivery, IUFD, mode of delivery, and antenatal thrombocytopenia, grand multiparity was found to be an independent protective factor for RBC transfusion (RR = 0.2 (0.007-0.56). After controlling for cofounders, grand multiparity alone is not associated with postpartum blood transfusion.

RESUMO

OBJECTIVE: To determine risk factors and to develop a risk prediction score for intrapartum cesarean delivery (CD) in women over 40 years old. STUDY DESIGN: A retrospective cohort study, in a single university-affiliated tertiary medical center. All women aged 40 years or more who planned a trial of labor between 2012 and 2022. Women who opted for an elective CD and those with non-viable fetuses were excluded. Maternal and neonatal characteristics of women who delivered vaginally were compared to those who underwent an intrapartum CD. Risk factors were examined using univariate and multivariate analysis. A score was developed to predict the need for intrapartum CD. We assessed a receiver operating characteristic curve to evaluate the performance of our model. MAIN OUTCOME MEASURE: An unplanned intrapartum cesarean section. RESULTS: During the study period, 122,583 women delivered at our center, of whom 6122 (4.9 %) aged 40 years or more attempted a trial of labor. Of them, 428 (7 %) underwent intrapartum CD. Several independent risk factors were identified, including nulliparity, regional anesthesia, induction of labor, use of antibiotics during labor, multiple gestation, previous cesarean delivery, and the presence of gestational diabetes or preeclampsia. A risk score model, employing a cut-off of 7, demonstrated successful prediction of intrapartum CD, with an area under the curve of 0.86. CONCLUSION: The score model for intrapartum CD can be used by caregivers to offer a more informed consultation to women aged 40 years or more deciding on the mode of delivery.

RESUMO

Cardiometabolic diseases are a major public-health concern owing to their increasing prevalence worldwide. These diseases are characterized by a high degree of interindividual variability with regards to symptoms, severity, complications and treatment responsiveness. Recent technological advances, and the growing availability of wearable and digital devices, are now making it feasible to profile individuals in ever-increasing depth. Such technologies are able to profile multiple health-related outcomes, including molecular, clinical and lifestyle changes. Nowadays, wearable devices allowing for continuous and longitudinal health screening outside the clinic can be used to monitor health and metabolic status from healthy individuals to patients at different stages of disease. Here we present an overview of the wearable and digital devices that are most relevant for cardiometabolic-disease-related readouts, and how the information collected from such devices could help deepen our understanding of metabolic diseases, improve their diagnosis, identify early disease markers and contribute to individualization of treatment and prevention plans.

RESUMO

(1) Background: Obstetric anal sphincter injuries (OASI) may complicate vaginal deliveries. The aim of the present study was to explore the incidence and clinical characteristics of OASI among Asian women living in a Western country compared to local Caucasian women. (2) Methods: A retrospective cohort study of 380 women diagnosed with OASI, following singleton vaginal deliveries, during a 10-year period (January 2011 to December 2020). Exclusion criteria: age < 18 years, stillbirth, and breech presentation. Demographic, clinical, and obstetrical data were obtained, and a comparison between Asian and Caucasian women was performed. (3) Results: There were 35 cases of OASI among 997 women of Asian ethnicity compared to 345 cases of OASI among 86,250 Caucasian women (3.5% vs. 0.4%, respectively, p < 0.001). Asian women endured a significantly higher rate of fourth-degree OASI (17.1%) even though they bore smaller newborns (3318 g vs. 3501 g, p = 0.004), and birth weights rarely exceeded 3800 g (2.8% vs. 25.8%, p < 0.001). Asian ethnicity was also associated with a significantly higher risk for blood transfusion following OASI and a lower tendency for postpartum follow up. (4) Conclusions: Immigrant women of Asian ethnicity had a nine-fold higher rate of OASI, much higher than previously reported. Furthermore, Asian women had higher rates of fourth-degree OASI.

RESUMO

Genome-wide association studies (GWASs) have provided numerous associations between human single-nucleotide polymorphisms (SNPs) and health traits. Likewise, metagenome-wide association studies (MWASs) between bacterial SNPs and human traits can suggest mechanistic links, but very few such studies have been done thus far. In this study, we devised an MWAS framework to detect SNPs and associate them with host phenotypes systematically. We recruited and obtained gut metagenomic samples from a cohort of 7,190 healthy individuals and discovered 1,358 statistically significant associations between a bacterial SNP and host body mass index (BMI), from which we distilled 40 independent associations. Most of these associations were unexplained by diet, medications or physical exercise, and 17 replicated in a geographically independent cohort. We uncovered BMI-associated SNPs in 27 bacterial species, and 12 of them showed no association by standard relative abundance analysis. We revealed a BMI association of an SNP in a potentially inflammatory pathway of Bilophila wadsworthia as well as of a group of SNPs in a region coding for energy metabolism functions in a Faecalibacterium prausnitzii genome. Our results demonstrate the importance of considering nucleotide-level diversity in microbiome studies and pave the way toward improved understanding of interpersonal microbiome differences and their potential health implications.

RESUMO

OBJECTIVE: To identify the clinical characteristics of pregnancy associated group A streptococcus (GAS) infection and predictors for intensive care unit (ICU) admission. METHODS: A retrospective cohort study of culture-proven pregnancy-related GAS infections in tertiary hospital Electronic medical records were reviewed, for cases of cultures positive GAS that were identified between January 2008 and July 2021. A GAS infection was defined by the isolation of the pathogen from a sterile liquid or tissue site. Blood and urine cultures were obtained from all patients with peripartum hyperpyrexia (fever >38 °C). Medical Personnel screening included cultures of the throat, rectum, and skin lesions (if present). In cases of hemodynamic instability patients were transferred ad hoc to ICU, according to the obstetrician and intensivist judgment. RESULTS: Of the 143,750 who delivered during the study period, 66 (0.04%) were diagnosed as having a pregnancy associated GAS infection. Of these, 57 patients presented postpartum, and represented the study cohort. The most common presenting signs and symptoms among puerperal GAS, were postpartum pyrexia (72%), abdominal pain (33%), and tachycardia (>100 bpm, 22%). 12 women (21.0%) developed streptococcal toxic shock syndrome (STSS. Predictors for STSS and ICU admission were: antibiotic administration >24 h from presentation postpartum, tachycardia, and a C-reactive protein level >200 mg/L. Women that received antibiotic prophylaxis during labor had a significantly lower rate of STSS (0 vs 10, 22.7%; p = .04). CONCLUSION: Deferral of medical intervention >24 h from the first registered abnormal sign had the most important impact on deterioration of women with invasive puerperal GAS.

RESUMO

OBJECTIVE: To assess the clinical significance of a low 180-minute glucose value in a 100 g oral glucose tolerance test (OGTT) and a single high abnormal value. METHODS: A retrospective cohort study. The study group included women with 180-minute plasma glucose levels of ≤60 mg/dL and one abnormal value in the OGTT. The control group was comprised of women with one abnormal value in the OGTT and normal 180-minute glucose value. The primary outcome was glycemic control, defined as fasting blood glucose measurements > 90 mg/dL or post-prandial glucose values >140 mg/dL or 120 mg/dL (one-hour and two-hour post-prandial, respectively) in >30% of the measurements. Secondary outcomes were the rate of insulin treatment and the perinatal outcome consisting of birthweight, large-for-gestational-age, and polyhydramnios. RESULTS: Three hundred and one women were included, 143 in the study group and 158 in the control group. Pre-pregnancy BMI, first trimester fasting glucose levels, previous GDM, and familial diabetes were similar for both groups. Suboptimal glycemic control was more prevalent among the women in the study group (14% vs. 5.1%, respectively, p= .01). The need for insulin treatment was similar in both groups. CONCLUSIONS: Women with one abnormal value and a 180-minute hypoglycemia in the OGTT are at increased risk for suboptimal glycemic control.

RESUMO

OBJECTIVE: To compare the pregnancy outcome of women who underwent cesarean section in the second stage of labor, with or without a vacuum extraction attempt. METHODS: A retrospective cohort study of women who underwent a cesarean section during the second stage of labor in a single tertiary university-affiliated medical center (2012-2019). Pregnancy outcome was compared for women who underwent cesarean section following a failed vacuum extraction to women who had cesarean section during the second stage of labor with no vacuum extraction attempt. Neonatal outcomes included umbilical artery pH less than 7.1, Apgar at 5 min < 7, hypoxemic ischemic encephalopathy and NICU admission. Maternal outcomes included duration of hospitalization, need for blood transfusion and need for re-surgery in 45 days. RESULTS: Overall, 88,375 women delivered during the study period. Of them, 120 women had a cesarean section following a failed vacuum (study group). Another 551 women underwent a cesarean section in the second stage of labor without a VE attempt (control group). The groups were similar with regard to obstetrical and demographic characteristics. The rates of umbilical artery pH < 7.1 (17.50% vs 6.53%, p < .001), NICU admission (13.33% vs 2.90%, p < .001), hypoxemic ischemic encephalopathy (5.83% vs 0.18%, p < .001) and epicranial sub-aponeurotic hemorrhage (16.67% vs 2.18%, p < .001) were significantly higher in the study group. No significant differences were found in maternal outcomes. In a sub-analysis including only labor with reassuring fetal heart tracing, failed vacuum attempt was associated with higher rate of NICU admission and epicranial hemorrhage (16.67% vs 3.13%, p = .009, 27.78% vs. 3.41, p = .001, respectively). CONCLUSION: Failed vacuum attempt is associated with a significant increased neonatal morbidity, but not increased maternal morbidity.

RESUMO

OBJECTIVE: We aimed to investigate the association of mild thrombocytopenia with postpartum hemorrhage (PPH) and blood transfusion among women with twin gestations. METHODS: A retrospective cohort study (Jan 2015 to May 2019) was performed. Women with twin pregnancies and pre-delivery mild thrombocytopenia were compared to those with normal platelet count. The primary outcome was the rate of PPH, defined as a composite of one or more of the following: (1) need for packed red blood cell transfusion; (2) postpartum hemoglobin decline of ≥3 g/dL; and (3) the use of postpartum uterotonics agents in addition to oxytocin. RESULTS: Of 1085 women who were included in final analysis, 315 (30.9%) had mild thrombocytopenia (and 770 (69.1%) served as controls. The rate of PPH was increased in the study group (14% vs. 9.4%, P = 0.03), as was the use of uterotonic agents (3.8% vs. 1.3%, respectively, P = 0.02). The rate of blood product transfusion and hemoglobin decline >3 g/dL was not significantly different between the groups. In multivariate logistic regression analysis, mild thrombocytopenia was associated with a higher risk for PPH (OR 1.55 [95% CI 1.02-2.35], P = 0.02). CONCLUSION: Mild thrombocytopenia in twin pregnancies is associated with an increased risk of interventions such as the use of uterotonic agents.

RESUMO

OBJECTIVE: We aimed to assess the efficacy of three different labor induction methods for non-viable third-trimester fetuses. METHODS: This retrospective cohort study included women who had an intra-uterine fetal death or termination of pregnancy at or after 28 weeks of gestation and underwent labor induction by either transcervical foley catheter and concomitant oxytocin infusion or regular doses of vaginal Prostin© or Propess©.The primary outcome was induction to the delivery interval. Secondary outcomes included the rate of women who delivered within 24 h, time spent in the delivery room, failed induction, adverse outcomes and reported occurrence of moderate to severe pain. RESULTS: Between January 2017 to June 2020, 107 women met the inclusion criteria. 25 women underwent induction of labor using transcervical foley catheter, 44 using Propess©, and 58 by Prostin©. The three groups were found to be demographically similar. The rate of women who delivered within 24 h was higher in the transcervical foley catheter group compared to the Propess© and Prostin© groups (72% vs 25% vs 29.3%, p < .001 respectively). Time to delivery was shorter among the transcervical foley catheter group compared to the Propess© and Prostin© groups (16.97 h vs 39.4 vs 39.3, p < .001 respectively). When comparing the Foley catheter group to both Propess© and Prostin©, moderate to severe pain was significantly more commonly reported in the prostaglandins groups (36.0% vs 50.0% vs 65.62%, p = .04). No difference was found in adverse outcomes, defined as intrapartum fever, post-partum hemorrhage and retained placenta. CONCLUSION: Cervical foley catheter with concomitant oxytocin infusion is the most effective method for induction of labor in third trimester non-viable in fetus compared to PGE2.
