RESUMO
OBJECTIVES: To identify factors associated with poor prognoses in newborns with a prenatal diagnosis of gastroschisis in eight hospitals in Bogota, Colombia, from 2011 to 2022. METHODS: A multi-center retrospective case-control study was conducted on newborns with gastroschisis in eight hospitals in Bogota, Colombia. Poor prognosis was defined as the presence of sepsis, intestinal complications, or death. RESULTS: The study included 101 patients. Preterm newborns under 32 weeks had a poor neonatal prognosis (OR 6.78 95â¯% CI 0.75-319). Oligohydramnios (OR 4.95 95â¯% CI 1.15-21.32) and staged closure with silo (OR 3.48; 95â¯% CI 1.10-10.96) were risk factors for neonatal death, and intra-abdominal bowel dilation of 20-25â¯mm was a factor for the development of intestinal complications (OR 3.22 95â¯% CI 1.26-8.23). CONCLUSIONS: Intra-abdominal bowel dilation between 20 and 25â¯mm was associated with intestinal complications, while oligohydramnios was associated with the risk of perinatal death, requiring increased antenatal surveillance of fetal wellbeing. Management with primary reduction when technically feasible is recommended in these infants, considering that the use of silos was associated with higher mortality.

BACKGROUND: In low-risk pregnancies, a third-trimester ultrasound examination is indicated if fundal height measurement and gestational age discrepancy are observed. Despite potential improvement in the detection of ultrasound abnormality, prior trials to date on universal third-trimester ultrasound examination in low-risk pregnancies, compared with indicated ultrasound examination, have not demonstrated improvement in neonatal or maternal adverse outcomes. OBJECTIVE: The primary objective was to determine if universal third-trimester ultrasound examination in low-risk pregnancies could attenuate composite neonatal adverse outcomes. The secondary objectives were to compare changes in composite maternal adverse outcomes and detection of abnormalities of fetal growth (fetal growth restriction or large for gestational age) or amniotic fluid (oligohydramnios or polyhydramnios). STUDY DESIGN: Our pre-post intervention study at 9 locations included low-risk pregnancies, those without indication for ultrasound examination in the third trimester. Compared with indicated ultrasound in the preimplementation period, in the postimplementation period, all patients were scheduled for ultrasound examination at 36.0-37.6 weeks. In both periods, clinicians intervened on the basis of abnormalities identified. Composite neonatal adverse outcomes included any of: Apgar score ≤5 at 5 minutes, cord pH <7.00, birth trauma (bone fracture or brachial plexus palsy), intubation for >24 hours, hypoxic-ischemic encephalopathy, seizure, sepsis (bacteremia proven with blood culture), meconium aspiration syndrome, intraventricular hemorrhage grade III or IV, periventricular leukomalacia, necrotizing enterocolitis, stillbirth after 36 weeks, or neonatal death within 28 days of birth. Composite maternal adverse outcomes included any of the following: chorioamnionitis, wound infection, estimated blood loss >1000 mL, blood transfusion, deep venous thrombus or pulmonary embolism, admission to intensive care unit, or death. Using Bayesian statistics, we calculated a sample size of 600 individuals in each arm to detect >75% probability of any reduction in primary outcome (80% power; 50% hypothesized risk reduction). RESULTS: During the preintervention phase, 747 individuals were identified during the initial ultrasound examination, and among them, 568 (76.0%) met the inclusion criteria at 36.0-37.6 weeks; during the postintervention period, the corresponding numbers were 770 and 661 (85.8%). The rate of identified abnormalities of fetal growth or amniotic fluid increased from between the pre-post intervention period (7.1% vs 22.2%; P<.0001; number needed to diagnose, 7; 95% confidence interval, 5-9). The primary outcome occurred in 15 of 568 (2.6%) individuals in the preintervention and 12 of 661 (1.8%) in the postintervention group (83% probability of risk reduction; posterior relative risk, 0.69 [95% credible interval, 0.34-1.42]). The composite maternal adverse outcomes occurred in 8.6% in the preintervention and 6.5% in the postintervention group (90% probability of risk; posterior relative risk, 0.74 [95% credible interval, 0.49-1.15]). The number needed to treat to reduce composite neonatal adverse outcomes was 121 (95% confidence interval, 40-200). In addition, the number to reduce composite maternal adverse outcomes was 46 (95% confidence interval, 19-74), whereas the number to prevent cesarean delivery was 18 (95% confidence interval, 9-31). CONCLUSION: Among low-risk pregnancies, compared with routine care with indicated ultrasound examination, implementation of a universal third-trimester ultrasound examination at 36.0-37.6 weeks attenuated composite neonatal and maternal adverse outcomes.

BACKGROUND: Adolescent pregnancies are more likely to be complicated with adverse perinatal outcomes. OBJECTIVE: Assess the sociodemographic and clinical characteristics of adolescents who have delivered singleton newborns. DESIGN: Retrospective cohort. SETTINGS: A tertiary training and research hospital in Turkey. PATIENTS AND METHODS: This was a review of adolescents and adults who delivered singleton newborns at a tertiary health center between January 2018 and June 2022. Pregnant adolescents were aged <20 years. MAIN OUTCOME MEASURES: Adverse maternal and perinatal outcomes. SAMPLE SIZE: 2233 pregnant women (754 adolescents and 1479 adults). RESULTS: Turkish nationality was significantly less prevalent in pregnant adolescents than pregnant adults (P=.001). Oligohydramnios, fetal growth restriction, perineal injury and postpartum intravenous iron treatment were significantly more prevalent in pregnant adolescents than pregnant adults (P<.05 for all). The neonates born to adolescent mothers had significantly lower birth weight and first minute Apgar score than the neonates born to adult mothers (P=.001 for both). Small for gestational age, need for intensive care and death were significantly more prevalent in neonates born to adolescent mothers than those born to adult mothers (P=.001 for all). Compared with pregnant adults, pregnant adolescents had a significantly higher risk of oligohydramnios (P=.001), preterm delivery (P=.024), intravenous iron treatment (P=.001), and small for gestational age (P=.001). CONCLUSION: Due to the refugee population received by Turkey, it would be prudent to expect more frequent adolescent pregnancies. Adolescent pregnancies are more likely to be complicated with low birth weight, oligohydramnios, preterm delivery, postpartum iron treatment, lower Apgar scores, need for neonatal intensive care and neonatal death. LIMITATION: Retrospective.

BACKGROUND: The prevalence of oligohydramnios ranges from 12 to 14% after 41 weeks to as high as 30% in post term pregnancies. Oligohydramnios poses a dilemma in the choice of mode of labor and delivery in a setup where there is lack of continuous electronic fetal monitoring during labor. The condition also puts the mother at risks of operative interventions and cesarean delivery. We aimed to asses the maternal and perinatal outcomes in pregnancies with oligohydramnios in late term and post term pregnancy in this study. METHODS: A cross-sectional study was conducted among mothers with diagnosis of oligohydramnios after 40+ 6 weeks of gestation at four hospitals at four public hospitals in Addis Ababa, Ethiopia from May 1, 2021 to September 30, 2021. Data were collected using structured questionnaire. Logistic regression were performed to assess factors associated with the adverse maternal and perinatal outcomes. RESULTS: From a total of 142 mothers with oligohydramnios in late term and post tem pregnancies, 40.8% delivered through cesarean section. Spontaneous labor and elective cesarean section were more likely to occurr in parous women (AOR 2.5, 95% CI 1.06-6.04, p = 0.04), but with less likely in those with secondary level education (AOR 0.13, 95% CI 0.02-0.74, p = 0.02). There was no statistically significant difference in adverse outcomes between those who had induction of labor and those who had either spontaneous labor or had elective cesarean section. CONCLUSIONS: The adverse maternal and perinatal outcomes in late term and post term pregnancies with oligohydramnios may not be different among different modes of delivery. Induction of labor can be safe in these particular group of women with intermittent auscultation with fetoscope in a setup where continuous electronic fetal monitoring is not readily available.

Objective: To analyze the effects of thalassemia minor on the incidence of amniotic fluid abnormalities and the blood loss of pregnant women during delivery based on the database. Methods: PubMed, EMBASE, EBSCO, Web of Knowledge and Ovid databases were searched for articles on the incidence of amniotic fluid abnormalities and the amount of bleeding during delivery in pregnant women with mild thalassemia; it can also be combined with manual retrieval for literature review. The data retrieval period was from the establishment of the database to June 2022. According to the Newcastle Ottawa scale score, the quality of the six included literature was evaluated, and the Revman processing software was used for meta-analysis. Results: The 6 included articles are all high-quality literature, including 364 cases in the case group and 689 cases in the control group. The publication years of the literature are mainly from 2013 to 2021, and they are all high-quality literature. All literature was blinded, and a total of 4 pregnancy outcomes were extracted from the 6 included literature, including oligohydramnios/oligohydramnios, postpartum hemorrhage, preterm delivery, and cesarean section. Compared to normal pregnant women, the level of postpartum bleeding in thalassemia pregnant women was significantly increased [RR = 2.40, 95% CI (1.63-3.54), P < .05], and the difference was statistically significant. Compared to normal pregnant women, thalassemia pregnant women have a significantly higher risk of developing excessive/insufficient amniotic fluid [RR = 2.71, 95% CI (2.52-2.81), P < .01], and the difference is statistically significant. Compared to normal pregnant women, pregnant women with thalassemia have a significantly higher risk of premature birth [RR = 3.02, 95% CI (1.84~4.96), P < .05], and the difference is statistically significant. Compared to normal pregnant women, the risk of cesarean section in thalassemia pregnant women is significantly increased [RR = 1.68, 95% CI (1.39-2.02), P < .05], and the difference is statistically significant. Conclusion: Thalassemia minor can increase the incidence of amniotic fluid abnormalities and the amount of bleeding during labor. In the future, we should strengthen the health education of pregnant women, improve the understanding of the disease, avoid or reduce the impact of thalassemia on newborns, improve the pregnancy outcome, and provide a more reliable basis for clinical decision-making.However, there are still certain limitations: (1) the literature selected in the study for the past 5 years is relatively small, and they are all single center, retrospective studies, and have a small sample size, resulting in insufficient accuracy of the results of the meta-analysis; (2) Some literature lacks blind methods, which may lead to language bias and implementation bias in the results; (3) The research time is still short, and it has not been clear how different types of thalassemia affect abnormal amniotic fluid volume and postpartum bleeding.

OBJECTIVE: Fetal Lower Urinary Tract Obstruction (LUTO) is associated with oligohydramnios and significant fetal morbidity, resulting in poor lung development and perinatal death. However, oligohydramnios may develop at different gestational periods, and the impact of timing on fetal outcomes remains unknown. Our objective was to characterize the impact onset of oligohydramnios had on prenatal outcomes. METHODS: This study is a retrospective cohort study of all patients with a prenatal diagnosis of LUTO at our tertiary referral center from 2014 to 2023. All patients underwent detailed ultrasonography and interdisciplinary counseling and were subsequently delivered at our institution. Data were obtained from electronic medical records and complete extraction was required for final inclusion. RESULTS: During the study time period, 93 patients met inclusion criteria of which 68 (73.1%) developed oligohydramnios during their pregnancy. 63 (93%) of these pregnancies resulted in livebirths with 28 (41.1%) perinatal deaths. Onset of oligohydramnios was earlier in pregnancies with perinatal death (23 vs. 28 weeks, p = 0.004) and associated with pulmonary hypoplasia. CONCLUSIONS: Our data show the impact of oligohydramnios timing in pregnancy on pulmonary hypoplasia and ultimately perinatal death. This allows for detailed patient counseling on the impact oligohydramnios may have on pregnancies by the gestational age of onset.

OBJECTIVES: Apparently uncomplicated low-risk pregnancies, especially first time births, account for a significant proportion of adverse birth outcomes. Improved risk stratification with a simple bedside scan on admission in early labor could potentially reduce adverse intrapartum outcomes. The aim of this feasibility study was to assess a cohort of low-risk subjects with admission ultrasonography at the onset of labor with a view to conducting a future randomized controlled trial (RCT). The objectives were three-fold; i) to determine the logistics of performing a labor admission ultrasound scan ii) to establish whether abnormal ultrasound features can be identified and iii) whether they are associated with emergency delivery and/or poor condition of the neonate at birth. METHODS: We performed a prospective cohort study of 295 participants with term singleton cephalic pregnancies admitted in early labor or for labor induction with non-fetal indications. The setting was a university teaching hospital in Ireland with almost 8000 births annually. A bedside ultrasound scan was performed to assess fetal biometry, amniotic fluid volume and placental maturity. Patients and their babies were followed up until hospital discharge. The outcomes of interest included image quality, time to perform a scan, oligohydramnios (Single Deepest Pool ≤ 2 cm), small for gestational age (SGA; abdominal circumference <10th centile), mature placenta (Grannum 2 or 3), pathological CTG, emergency cesarean section (CS), fetal acidosis (cord arterial pH <7.10 or base excess <-12.0), low Apgar score <7 at 5 min and neonatal unit admission. RESULTS: Image quality was optimal in 274 of the 295 scans (93%) and 271 (92%) were completed in less than 10 min. Of this low-risk population, 67 of 294 (23%) had oligohydramnios, 11 (4%) were small for gestational age and 87 (30%) had a mature placenta (Grannum grade 2). The incidence of pathological CTG and emergency CS was higher among patients with oligohydramnios than those with a normal scan but did not reach statistical significance; Odds Ratio 3.40 (95% Confidence Intervals 0.55 to 20.92) and OR 1.43 (95% CI 0.66 to 3.08) respectively. The mean birthweight was significantly lower in those with oligohydramnios -139 g (95% CI -248 to -30) and admission scan detected SGA -357 g (95% CI -557 to -137). Adverse perinatal outcomes were uncommon with a higher incidence of fetal acidosis (pH < 7.10) in the oligohydramnios group. The incidence of neonatal unit admission >24 h was higher in the oligohydramnios group but not statistically significant; OR 3.75 (95% CI 0.61 to 22.97). Results for SGA alone were non-significant and results for oligohydramnios and SGA combined were similar to those for oligohydramnios alone. CONCLUSIONS: Admission ultrasonography is feasible in a routine clinical setting, but evidence of benefit is weak and does not currently justify a randomized controlled trial.

Oligohydramnios has been a topical issue in obstetrics. The prevalence of oligohydramnios ranges from 1 to 5%. Conflicting data exists concerning its effects on adverse perinatal outcome. This study aims to assess perinatal outcomes of oligohydramnios at the Mekelle Public Hospitals from April 1, 2018 - March 31, 2019. This was a cross-sectional study and a total population purposive sampling method was employed to collect data prospectively. During the study period, there were a total of 10,451 deliveries in both hospitals. Oligohydramnios complicated 332 pregnancies (3.2%, 95%CI: 2.9%, 3.5%) across all gestations and 273 pregnancies (2.6%, 95% CI: 2.3%, 2.9%) at term. The composite adverse perinatal outcome rate was 29.7% (95% CI, 24.5, 35.4). Primigravidity and presenting at post-term gestation were associated with adverse perinatal outcome. Nearly 70% of mothers gave birth via Cesarean delivery. Oligohydramnios was found to be associated with a significant increase in adverse newborn and maternal outcomes in the study setting. Although a significant proportion of mothers underwent Cesarean delivery for a perceived increased complications associated with vaginal delivery in this population of patients, Cesarean delivery was found to not improve perinatal outcome. Primigravids and postdated pregnancies must receive increased surveillance to detect oligohydramnios early and to institute appropriate and timely interventions. Indications for Cesarean delivery in patients complicated by oligohydramnios must be carefully examined to balance the benefit on the perinatal outcome on the one hand and to avoid unnecessary major surgery with potential fatal maternal complications on the other.

OBJECTIVE: To analyze neonatal outcomes in very-low-birthweight (VLBW) infants depending on the presence of preterm premature rupture of membranes (PPROM), oligohydramnios, or both. METHODS: The electronic medical records of VLBW infants admitted during the study period, January 2013 to September 2018, were reviewed. Neonatal outcomes (primary outcome: neonatal death; secondary outcome: neonatal morbidity) were compared depending on whether the infant was affected by PPROM or oligohydramnios. Logistic regression analysis was performed to assess the association of PPROM and oligohydramnios with neonatal outcomes. RESULTS: Three hundred and nineteen VLBW infants were included: (1) 141 infants in the PPROM group vs. 178 infants in the non-PPROM group, and (2) 54 infants in the oligohydramnios group vs. 265 infants in the non-oligohydramnios group. The infants affected by PPROM were at significantly younger gestational ages at birth with lower 5-min Apgar scores than those not affected by PPROM. Histologic chorioamnionitis was significantly more frequent in the PPROM group than in the non-PPROM group. The proportions of small-for-gestational-age infants and infants affected by multiple births were significantly higher in the non-PPROM group. The median (interquartile range) PPROM latency and onset were 50.5 (9.0 - 103.0) h and 26.6 (24.1 - 28.5) weeks, respectively. Based on the logistic regression analysis assessing the association of PPROM and oligohydramnios with the significant neonatal outcome, oligohydramnios was significantly associated with neonatal death (odds ratio [OR] = 2.831, 95% confidence interval [CI] 1.447 - 5.539), air leak syndrome (OR = 2.692, 95% CI 1.224 - 5.921), and persistent pulmonary hypertension (PPH) (OR = 2.380, 95% CI 1.244 - 4.555). PPROM per se was not associated with any neonatal outcome. However, early onset PPROM and prolonged PPROM latency were associated with neonatal morbidity and mortality. When PPROM was accompanied by oligohydramnios, it was associated with increased odds for PPH (OR = 2.840, 95% CI 1.335 - 6.044), retinopathy of prematurity (OR = 3.308, 95% CI 1.325 - 8.259), and neonatal death (OR = 2.282, 95% CI 1.021 - 5.103). CONCLUSION: PPROM and oligohydramnios affect neonatal outcomes differently. Oligohydramnios, but not PPROM, is a significant risk factor for adverse neonatal outcomes, which is presumably related to pulmonary hypoplasia. Prenatal inflammation appears to complicate neonatal outcomes in infants affected by early PPROM and prolonged PPROM latency.

OBJECTIVE: We aimed in this study to evaluate the impact of maternal interleukin -17A and the activity of the illness on pregnancy outcomes in Psoriatic arthritis (PsA) and ankylosing spondylitis (AS) patients. METHODS: This prospective cohort research was carried out on 48 Psoriatic arthritis and ankylosing spondylitis pregnant women attending the inpatient and outpatient clinics of the Rheumatology & Rehabilitation and Obstetrics & Gynecology Departments, Faculty of Medicine, Zagazig University Hospitals in Egypt and 30 apparently healthy age- and sex-matched pregnant women between January 1,2018, and December 31, 2019. RESULTS: The study group patients had a higher risk of preterm labour (32-36 weeks gestation) (aRR 1.80, 95% CI 0.79-4.17), oligohydramnios (aRR 3.15, 95% CI 1.26-8.42), Caesarean delivery (aRR 1.57, 95% CI 1.41-2.68), and delivering infants small for gestational age (aRR 7.04, 95% CI 2.36-12.42). There was significant difference between the control group and the study groups regarding the level of IL-17A. CONCLUSION: Many females with PsA and AS have uninhibited pregnancy with regard to adverse events, but in comparison with normal pregnancies particularly with high IL-17A during the third trimester we noticed a growing risk of preterm labour, oligohydramnios and cesarean section. Further studies are needed to evaluate high maternal IL-17A levels and fetal outcomes.

BACKGROUND: Oligohydramnios is associated with poor maternal and perinatal outcomes. In low-resource countries, including Uganda, oligohydramnios is under-detected due to the scarcity of ultrasonographic services. We determined the prevalence and associated factors of oligohydramnios among women with pregnancies beyond 36 weeks of gestation at Mbarara Regional Referral Hospital (MRRH) in Southwestern Uganda. METHODS: We conducted a hospital-based cross-sectional study from November 2019 to March 2020. Included were women at gestational age > 36 weeks. Excluded were women with ruptured membranes, those in active labour, and those with multiple pregnancies. An interviewer-administered structured questionnaire was used to capture demographic, obstetric, and clinical characteristics of the study participants. We determined oligohydramnios using an amniotic fluid index (AFI) obtained using an ultrasound scan. Oligohydramnios was diagnosed in participants with AFI ≤ 5 cm. We performed multivariable logistic regression to determine factors associated with oligohydramnios. RESULTS: We enrolled 426 women with a mean age of 27 (SD ± 5.3) years. Of the 426 participants, 40 had oligohydramnios, for a prevalence of 9.4% (95%CI: 6.8-12.6%). Factors found to be significantly associated with oligohydramnios were history of malaria in pregnancy (aOR = 4.6; 95%CI: 1.5-14, P = 0.008), primegravidity (aOR = 3.7; 95%CI: 1.6-6.7, P = 0.002) and increasing gestational age; compared to women at 37-39 weeks, those at 40-41 weeks (aOR = 2.5; 95%CI: 1.1-5.6, P = 0.022), and those at > 41 weeks (aOR = 6.0; 95%CI: 2.3-16, P = 0.001) were more likely to have oligohydramnios. CONCLUSION: Oligohydramnios was detected in approximately one out of every ten women seeking care at MRRH, and it was more common among primigravidae, those with a history of malaria in pregnancy, and those with post-term pregnancies. We recommend increased surveillance for oligohydramnios in the third trimester, especially among prime gravidas, those with history of malaria in pregnancy, and those with post-term pregnancies, in order to enable prompt detection of this complication and plan timely interventions. Future longitudinal studies are needed to assess clinical outcomes in women with oligohydramnios in our setting.

OBJECTIVE: To compare the rate and severity of abnormal amniotic fluid volumes (oligohydramnios or polyhydramnios), as well as the distribution of amniotic fluid levels, in pregnancies with and without diabetes. METHODS: We performed a retrospective cohort study of singleton nonanomalous pregnancies receiving an ultrasound examination (USE) in the third trimester. Pregnancies were categorized into those with and without diabetes and subcategorized by diabetes type. The primary outcomes were oligohydramnios or polyhydramnios. Polyhydramnios was also examined by severity. The association between maternal diabetes status and oligohydramnios or polyhydramnios was assessed using logistic regression. In addition, we computed gestational age-specific amniotic fluid index (AFI) and deepest vertical pocket (DVP) centiles for pregnancies with and without diabetes. RESULTS: There were 60,226 USEs from 26,651 pregnancies that met inclusion criteria. There were 3992 (15.0%) pregnancies with diabetes and 22,659 (85.0%) without diabetes. Using AFI, the rate of polyhydramnios was 10.5 versus 3.8% (odds ratio [OR] 2.95; 95% confidence interval [CI] 2.62-3.32) for pregnancies with versus without diabetes, respectively; using DVP, the rate of polyhydramnios was 13.9 versus 5.4% (OR 2.84; 95% CI 2.56-3.15). Rates of oligohydramnios were also increased in pregnancies with diabetes (3.3 versus 2.6%; OR 1.26; 95% CI 1.04-1.52). The AFI and DVP were significantly higher in the cohort with diabetes between 28 and 36 weeks. CONCLUSION: Within our study population, pregnancies with diabetes had increased rates of oligohydramnios and polyhydramnios as well as increased gestational age-specific amniotic fluid volumes between 28 and 36 weeks. A higher prevalence of polyhydramnios was observed using DVP as compared to AFI; nevertheless, associations were similar using either method.

OBJECTIVE: To investigate whether the severity of isolated oligohydramnios at term is associated with increased rates of adverse perinatal outcome. STUDY DESIGN: A retrospective study conducted in a single medical center from 2017 to 2019. All low-risk pregnancies with incidental isolated oligohydramnios at term were included. The degree of oligohydramnios was arbitrarily classified into mild (AFI = 41-50 mm), moderate (AFI = 21-40 mm) and severe (AFI = 0-20 mm). RESULT: A total of 610 women were included: 202 with a mild (33.1%), 287 moderate (47.0%), and 121 severe oligohydramnios (19.8%). Non-reassuring monitor requiring immediate delivery and worse composite neonatal outcome were more common among severe than mild or moderate oligohydramnios (14.0% and 6.4%, 7.3% respectively; p = .039 and 19.8%, 10.9% and 11.8%, respectively; p = .048). CONCLUSION: Low-risk pregnancies with isolated severe oligohydramnios at term have a higher tendency toward non-reassuring fetal monitoring requiring prompt delivery and adverse neonatal outcomes, this calls for close intrapartum surveillance.

OBJECTIVE: Isolated oligohydramnios (IO) - oligohydramnios in the absence of maternal or gestational comorbidity is debated as an indication for induction of labor. Previous meta-analyses regarding perinatal outcomes of IO at term have yielded conflicting results. We aimed to investigate the neonatal outcomes among gestations with IO delivered at 36°/7-396/7. METHODS: The study cohort included all women undergoing a trial of labor between during 2011 and 2019 of a singleton gestation with cephalic presentation between 36°/7 and 40°/7. We allocated the study groups into women with IO and those with normal amniotic fluid volume. Neonatal outcomes were compared between the groups and in relation to gestational age and induction of labor. RESULTS: Overall, there were 529/17,709 (3.0%) IO cases. IO was associated with maternal age <25 years (OR [95% CI] 1.62 (1.20-2.20), p = .001). Induction of labor was more common with IO (OR [95% CI] 1.33 (1.05-1.69) p = .01. IO was associated with preterm delivery (OR [95% CI] 1.81 (1.36-2.40), p < .001). The rate of neonatal adverse outcome did not differ between study groups. Overall composite adverse neonatal outcome occurred among 1,399/17,709 (7.9%) deliveries. Adverse neonatal outcome was associated with induction of labor (OR [95% CI] 1.61 (1.40-1.86), p < .001) and low birth weight (OR [95% CI] 7.41 (6.27-8.75), p < .001). When Stratified by gestational age, neonatal adverse outcome did not differ between IO and no IO groups. When examining cases of induction of labor per gestational age, induction of labor at 36 weeks among IO gestations, was associated with adverse neonatal outcome as compared to no IO group (OR [95% CI] 5.7 (1.23-26.3), p = .04). CONCLUSIONS: Induction of labor in gestations complicated by IO at 36 weeks gestational age is associated with an increased risk for adverse neonatal outcome. Our study results adds to the current literature regarding outcomes of IO and time of delivery. SYNOPSIS: Induction of labor in gestations complicated by IO at 36 weeks gestational age is associated with an increased risk for adverse neonatal outcome.

Amniotic fluid is crucial for the well-being of the fetus. Recent studies suggest that dehydration in a pregnant woman leads to oligohydramnios. We assessed the variation in the amniotic fluid index (AFI) during the summer and non-summer seasons and evaluated neonatal outcomes. We retrospectively reviewed electrical medical records of pregnant women who visited the Konkuk University Medical Center for antenatal care, between July 2005 and July 2019. A total of 19,724 cases from 6438 singleton pregnant women were included after excluding unsuitable cases. All AFI values were classified as 2nd and 3rd trimester values. Additionally, borderline oligohydramnios (AFI, 5-8) and normal AFI (AFI, 8-24) were assessed according to the seasons. The average AFI between the summer and non-summer season was statistically different only in the 3rd trimester; but the results were not clinically significant. In the 3rd trimester, the summer season influenced the increased incidence of borderline oligohydramnios. The borderline oligohydramnios group showed an increased small-for-gestational-age (SGA) rate and NICU admission rate. In the summer season, the incidence of borderline oligohydramnios was seen to increase. This result would be significant for both physicians and pregnant women.

BACKGROUND: Over than one third (28-58%) of pregnancy-associated breast cancer (PABC) cases are characterized by positive epidermal growth factor receptor 2-positive (HER2) expression. Trastuzumab anti-HER2 monoclonal antibody is still the benchmark treatment of HER2-positive breast tumors. However, FDA has categorized Trastuzumab as a category D drug for pregnant patients with breast cancer. This systemic review aims to synthesize all currently available data of trastuzumab administration during pregnancy and provide an updated view of the effect of trastuzumab on fetal and maternal outcome. METHODS: Eligible articles were identified by a search of MEDLINE bibliographic database and ClinicalTrials.gov for the period up to 01/09/2020; The algorithm consisted of a predefined combination of the words "breast", "cancer", "trastuzumab" and "pregnancy". This study was performed in accordance with the PRISMA guidelines. RESULTS: A total of 28 eligible studies were identified (30 patients, 32 fetuses). In more than half of cases, trastuzumab was administered in the metastatic setting. The mean duration of trastuzumab administration during gestation was 15.7 weeks (SD: 10.8; median: 17.5; range: 1-32). Oligohydramnios or anhydramnios was the most common (58.1%) adverse event reported in all cases. There was a statistically significant decrease in oligohydramnios/anhydramnios incidence in patients receiving trastuzumab only during the first trimester (P = 0.026, Fisher's exact test). In 43.3% of cases a completely healthy neonate was born. 41.7% of fetuses exposed to trastuzumab during the second and/or third trimester were born completely healthy versus 75.0% of fetuses exposed exclusively in the first trimester. All mothers were alive at a median follow-up of 47.0 months (ranging between 9 and 100 months). Of note, there were three cases (10%) of cardiotoxicity and decreased ejection fraction during pregnancy. CONCLUSIONS: Overall, treatment with trastuzumab should be postponed until after delivery, otherwise pregnancy should be closely monitored.

BACKGROUND: In accordance with the guidelines for the expectant management of women exposed to previable preterm premature rupture of membrane, we compared neonatal outcomes according to the latent period from membrane rupture to delivery among extremely preterm infants exposed to maternal preterm premature rupture of membrane using the Korean Neonatal Network database. METHODS: Of the 3,305 extremely preterm infants born at 23-27 weeks' gestation between 2014 and 2017 who were registered in the Korean Neonatal Network, 1,464 infants were born to pregnant women who were exposed to preterm premature rupture of membrane. The short latency group was defined as infants born with a latent period between membrane rupture and delivery < 7 days (n = 450), whereas the prolonged latency group was defined as infants born with a latent period of ≥ 7 days (n = 434). Using well-established risk factors for adverse short-term outcomes, multivariate logistic regression analysis was performed to assess a prolonged latent period in preterm premature rupture of membrane as an independent risk factor for neonatal outcomes in extremely preterm infants exposed to preterm premature rupture of membrane. RESULTS: The mean gestational age at membrane rupture in the prolonged latency group was significantly lower than that in the short latency group (22.7 ± 2.5 vs. 25.4 ± 1.3 weeks, P < 0.001). Nevertheless, the mean gestational age at delivery and birth weight were not significantly different between the two groups. The incidence of oligohydramnios and histologic chorioamnionitis in the prolonged latency group was significantly higher than that in the short latency group (38.7 [155/401] vs. 26.1 [105/403], 69.8 [270/384] vs. 61.0 [242/397], respectively, P < 0.05). The survival rate in the prolonged latency group did not differ from that in the short latency group (71.2 [309/434] vs. 73.3 [330/450], P = 0.478). Although the prolonged latency group was not associated with mortality during hospitalization in the multivariate logistic regression analysis, the prolonged latency group's early pulmonary hypertension and bronchopulmonary dysplasia rates were increased by 1.8 and 1.5 times, respectively. CONCLUSION: A prolonged latent period of 7 days or more does not affect the survival rate but increases the risk of bronchopulmonary dysplasia occurrence among extremely preterm infants who are exposed to maternal preterm premature rupture of membrane.

OBJECTIVES: To present the consequences of and risk factors for abnormal bleeding after ECV (external cephalic version). METHODS: We conducted a retrospective chart review at a single center in Japan. Abnormal bleeding was defined as vaginal bleeding and/or intrauterine hemorrhage. We descriptively assessed birth outcomes among women with abnormal bleeding, and investigated the risk factors using a logistic regression analysis. RESULTS: Of 477 women who received ECV, 39 (8.2%) showed abnormal bleeding, including 16 (3.4%) with intrauterine hemorrhage. Of the 16 women with intrauterine hemorrhage, 14 required emergency cesarean section; none experienced placental abruption, a low Apgar score at 5 min (<7), or low umbilical cord artery pH (<7.1). Among 23 women who had vaginal bleeding without intrauterine hemorrhage, four cases underwent emergency cesarean section and one case of vaginal delivery involved placental abruption. The risk of abnormal bleeding was higher in women with a maximum vertical pocket (MVP) of <40 mm in comparison to those with an MVP of >50 mm (adjusted odds ratio [OR]: 3.48, 95% confidence interval [CI]: 1.23-9.90), as was higher in women with unsuccessful ECV than in those with successful ECV (aOR: 4.54, 95% CI: 1.95-10.6). CONCLUSIONS: A certain number of women who underwent ECV had abnormal bleeding, including vaginal bleeding and/or intrauterine hemorrhage, many of them resulted in emergency cesarean section. Although all of cases with abnormal bleeding had good birth outcomes, one case of vaginal bleeding was accompanied by placental abruption. Small amniotic fluid volume and unsuccessful ECV are risk factors for abnormal bleeding.

BACKGROUND: Amniotic fluid provides necessary fluid and growth factors for normal development of fetal lungs, cushions the umbilical cord from compression and protects the fetus. This study aims to compare the perinatal outcome between pregnancy with borderline and normal Amniotic Fluid Index that provide greatest chance for appropriate safe delivery with least maternal fetal and neonatal risk. METHODS: A total of 94 singleton full term pregnant women were included in the study-at Kathmandu Model Hospital from February to August 2020. Forty Seven women each with Amniotic Fluid Index 5-8 cm was taken as borderline oligohydramnios group and Amniotic Fluid Index 8.1-24 cm was taken as normal group. Ultrasonography was taken as the medium for measuring Amniotic Fluid Index. RESULTS: The rate of intra-partum fetal distress, meconium-stained amniotic fluid, low birth weight and neonatal intensive care unit admission were not statistically significant between the two groups while rate of cesarean section was noted to be 76.6% in exposed groups as compared to 44.7% among women with non-exposed normal group [RR=1.71; 95%CI: 1.2-2.44 p=0.006]. CONCLUSIONS: We concluded that in cases of borderline oligohydramnios there was higher risk of operative delivery.
