RESUMEN
BACKGROUND: The recent paradigm shift of treating individuals at risk of late preterm birth with antenatal corticosteroids warrants an assessment of the effect of single dosage. OBJECTIVE: To compare outcomes of neonates born in the late preterm period (34.0-36.6 weeks) after a single dose of antenatal corticosteroids vs placebo. STUDY DESIGN: We performed a secondary analysis of the Antenatal Late Preterm Steroids trial. All individuals enrolled in the parent trial who received only a single dose of either antenatal corticosteroids or placebo and delivered within 24 hours were included. Primary outcome was a composite of respiratory support at 72 hours, including continuous positive airway pressure or high-flow nasal cannula ≥2 hours, oxygen with an inspired fraction of ≥30% for ≥4 hours, or mechanical ventilation. RESULTS: Of the 2831 individuals in the parent trial, 1083 (38.3%) met inclusion criteria; of them, 539 (49.8%) received a single dose of antenatal corticosteroids and 544 (50.2%) a single placebo dose. The placebo and antenatal corticosteroids groups had similar demographic and clinical characteristics. There was no difference in the rate of the primary respiratory outcome (adjusted risk ratio, 1.12; 95% confidence interval, 0.85-1.47) or in the rate of respiratory distress syndrome (adjusted risk ratio, 1.47; 95% confidence interval, 0.95-2.26) between those who received a single antenatal corticosteroids dose and placebo. An exploratory stratification by randomization-to-delivery intervals of 12-hour increments also showed no association with lower primary respiratory outcome rates. CONCLUSION: In individuals with late preterm birth pregnancies who received antenatal corticosteroids and delivered before a second dose, there were no differences in neonatal respiratory morbidities compared with placebo. However, this study is not powered to detect treatment efficacy.
RESUMEN
BACKGROUND: The investigation of the fetal umbilical-portal venous system is based on the premise that congenital anomalies of this system may be related to adverse perinatal outcomes. Several small retrospective studies have reported an association between umbilical-portal-systemic venous shunts and intrauterine growth restriction. However, the prevalence of portosystemic shunts in the fetal growth restricted population is yet to be determined. OBJECTIVE: The aims of this study were (1) to determine the prevalence of fetal umbilical-portal-systemic venous shunts in pregnancies complicated by intrauterine growth restriction and (2) to compare the perinatal and neonatal outcomes of pregnancies with intrauterine growth restriction with and without umbilical-portal-systemic venous shunts. STUDY DESIGN: This was a prospective, cross-sectional study of pregnancies diagnosed with intrauterine growth restriction, as defined by the Society for Maternal-Fetal Medicine intrauterine growth restriction guidelines. All participants underwent a detailed anomaly scan, supplemented with a targeted scan of the fetal portal system. Venous shunts were diagnosed using color Doppler mode. The perinatal outcomes of pregnancies with intrauterine growth restriction with and without umbilical-portal-systemic venous shunts were compared. RESULTS: A total of 150 cases with intrauterine growth restriction were recruited. The prevalence of umbilical-portal-systemic venous shunts in our cohort was 9.3% (n=14). When compared with the control group (intrauterine growth restriction without umbilical-portal-systemic venous shunts, n=136), the study group had a significantly lower mean gestational age at the time of intrauterine growth restriction diagnosis (29.7±5.6 vs 32.47±4.6 weeks of gestation; P=.036) and an earlier gestational age at delivery (33.50±6.0 vs 36.13±2.8; P=.005). The study group had a higher rate of fetal death (21.4% vs 0.7%; P<.001) and, accordingly, a lower rate of live births (71.4% vs 95.6%; P=.001). Additional associated fetal vascular anomalies were significantly more prevalent in the study group than in the control group (35.7% vs 4.4%; P≤.001). The rate of other associated anomalies was similar. The study group had a significantly lower rate of abnormal uterine artery Doppler indices (0% vs 40.4%; P=.011) and a higher rate of abnormal ductus venosus Doppler indices (64.3% vs 23%; P=.001). There were no cases of hypertensive disorders of pregnancy in the study group, whereas the control group had an incidence of 12.5% (P=.16). Other perinatal and neonatal outcomes were comparable. CONCLUSION: Umbilical-portal-systemic venous shunt is a relatively common finding among fetuses with growth restriction. When compared with pregnancies with intrauterine growth restriction with a normal portal system, these pregnancies complicated by intrauterine growth restriction and an umbilical-portal-systemic venous shunt are associated with a different Doppler flow pattern, an increased risk for fetal death, earlier presentation of intrauterine growth restriction, a lower gestational age at delivery, additional congenital vascular anomalies, and a lower rate of pregnancy-induced hypertensive disorders. Meticulous sonographic evaluation of the portal system should be considered in the prenatal workup of intrauterine growth restriction, as umbilical-portal-systemic venous shunts may affect perinatal outcomes.

OBJECTIVE: The aim of this study was to describe the anatomy of the portal system in fetuses with persistent right umbilical vein (PRUV). METHODS: Prospective observational study of fetuses diagnosed with PRUV. All patients underwent a comprehensive portal system anatomy scan supplemented by two-dimensional (2D) and three-dimensional (3D) color doppler modalities. RESULTS: 29 fetuses with PRUV were studied. We perceived an identical anatomical pattern in 28 fetuses. The right umbilical vein drains to the portal sinus (future right portal vein, RPV), which has a configuration of a left portal vein (LPV) in the normal left portal system, with three emerging branches: inferior (RPVi), medial (RPVm) and superior (RPVs). The RPV then courses to the left, towards the stomach to the point of the bifurcation of the main portal vein (MPV) to become the left portal vein. The LPV has an RPV configuration in a normal portal system with anterior (LPVa) and posterior (RPVp) branches. This anatomical layout mimics a mirror image of the normal anatomy of left portal system. CONCLUSION: PRUV has unique umbilical portal venous anatomy, which is a mirror image of the normal left portal system. It can be demonstrated prenatally and serve as an additional tool for prenatal diagnosis of PRUV.

Objective To compare maternal and neonatal outcomes between labor induction versus CD without labor among nulliparous individuals with class III obesity (body mass index ≥ 40 kg/m2). Study design A retrospective cohort study of all nulliparous singleton deliveries ≥ 37 weeks with a BMI ≥ 40 kg/m2 at delivery between March 2020 and February 2022. We excluded individuals with spontaneous labor, fetal malformations, and stillbirths. The primary outcome was a composite of maternal mortality and morbidity, including infectious and hemorrhagic morbidity. The secondary outcome was a neonatal composite. A subgroup analysis evaluated patients with a body mass index ≥ 50 kg/m2. Another subgroup analysis compared outcomes between CD without labor and an indicated CD following induction. A multivariable logistic regression was applied. For adjustment, we used possible confounders identified in a univariate analysis. Results Among 8,623 consecutive deliveries during the study period, 308 (4%) met the inclusion criteria. Among them, 250 (81%) underwent labor induction, and 58 (19%) had a CD without labor. The most common indications for CD without labor were fetal malpresentation (26; 45%), suspected macrosomia (8; 14%), and previous myomectomy (5; 9%). Indicated CD occurred in 140 (56%) of the induced individuals, with the two leading indications being labor arrest (87; 62%) and non-reassuring fetal heart rate tracing (51; 36%). The rates of composite maternal morbidity (aOR 2.14, 95% CI 0.64-7.13) and composite neonatal morbidity (aOR 3.62, 95% CI 0.42-31.19) did not differ following a CD without labor compared to labor induction. The subgroup analyses did not demonstrate different outcomes between groups. Conclusions Among nulliparous individuals with class III obesity at term who underwent induction, more than 50% had indicated CD; the rate of short term maternal and neonatal morbidity, however, did not differ between labor induction and CD without labor.
RESUMEN
OBJECTIVE: This study aimed to ascertain the outcomes associated with a cervical cerclage among individuals with a history of previable prelabor rupture of membranes (PROM). STUDY DESIGN: This study was a retrospective cohort study conducted at a single tertiary center between 2011 and 2021. We included individuals with a history of previable (before 24 weeks) PROM and the subsequent viable pregnancy. Women with multifetal gestation, preterm birth (PTB) or cerclage in previous gestation, or abdominal cerclage after trachelectomy were excluded. Primary outcome was PTB rate (delivery <37 weeks). Recurrence of preterm PROM and adverse composite maternal and neonatal outcomes (CMO and CNO) were evaluated as secondary outcomes. CMO included any of the following: suspected chorioamnionitis, endometritis, red blood cell transfusion, uterine rupture, unplanned hysterectomy, or death. CNO included any of the following: previable PTB (<24 weeks of gestation), bronchopulmonary dysplasia, grade 3 or 4 intraventricular hemorrhage, necrotizing enterocolitis, mechanical ventilation, seizures, hypoxic ischemic encephalopathy, or death. RESULTS: During the study period, 118 individuals had a history of previable PROM and a documented subsequent pregnancy, out of which 74 (62.7%) met inclusion criteria. Nineteen (25.7%) of eligible individuals underwent a cerclage for prior previable PROM and were compared with controls (n = 55, 74.3%). Women who underwent a cerclage had higher rates of PTB < 37 weeks (63.2 vs. 10.9%, p < 0.001; odds ratio [OR]: 14.00, 95% confidence interval [CI]: 3.97-49.35) and < 34 weeks (21.1 vs. 3.6%, p = 0.03; OR: 7.07, 95% CI: 1.18-42.39) compared with those without cerclage. Furthermore, recurrent preterm PROM and previable PTB rates were higher among patients who underwent cerclage. The survival curve further indicated that individuals with cerclage delivered earlier. CMO and CNO rates were similar in those with and without cerclage. CONCLUSION: Cerclage placement in individuals with prior previable PROM was associated with higher rates of recurrent preterm PROM and PTB. KEY POINTS: · The management of individuals in a subsequent pregnancy following previable PROM is a conundrum.. · Cerclage following previable PROM is associated with higher rates of recurrent preterm PROM and PTB.. · Composite maternal and neonatal outcome rates were similar in those with and without cerclage..
RESUMEN
OBJECTIVE: This study aimed to evaluate whether the suspension of intrapartum maternal oxygen supplementation for nonreassuring fetal heart rate is associated with adverse perinatal outcomes. STUDY DESIGN: A retrospective cohort study, including all individuals that underwent labor in a single tertiary medical center. On April 16, 2020, the routine use of intrapartum oxygen for category II and III fetal heart rate tracings was suspended. The study group included individuals with singleton pregnancies that underwent labor during the 7 months between April 16, 2020, and November 14, 2020. The control group included individuals that underwent labor during the 7 months before April 16, 2020. Exclusion criteria included elective cesarean section, multifetal pregnancy, fetal death, and maternal oxygen saturation <95% during delivery. The primary outcome was defined as the rate of composite neonatal outcome, consisting of arterial cord pH <7.1, mechanical ventilation, respiratory distress syndrome, necrotizing enterocolitis, intraventricular hemorrhage grade 3/4, and neonatal death. The secondary outcome was the rate of cesarean and operative delivery. RESULTS: The study group included 4,932 individuals, compared with 4,906 individuals in the control group. The suspension of intrapartum oxygen treatment was associated with a significant increase in the rate of composite neonatal outcome (187 [3.8%] vs. 120 [2.4%], p < 0.001), including the rate of abnormal cord arterial pH <7.1 (119 [2.4%] vs. 56 [1.1%], p < 0.01). A higher rate of cesarean section due to nonreassuring fetal heart rate was noted in the study group (320 [6.5%] vs. 268 [5.5%], p = 0.03).A logistic regression analysis revealed that the suspension of intrapartum oxygen treatment was independently associated with the composite neonatal outcome (adjusted odds ratio = 1.55 [95% confidence interval, 1.23-1.96]) while adjusting for suspected chorioamnionitis, intrauterine growth restriction, and recent coronavirus disease 2019 exposure. CONCLUSION: Suspension of intrapartum oxygen treatment for nonreassuring fetal heart rate was associated with higher rates of adverse neonatal outcomes and urgent cesarean section due to fetal heart rate. KEY POINTS: · The available data on intrapartum maternal oxygen supplementation are equivocal.. · Suspension of maternal oxygen for nonreassuring fetal heart rate during labor was associated with adverse neonatal outcomes.. · Oxygen treatment might still be important and relevant during labor..
RESUMEN
OBJECTIVE: We aimed to compare the telomere length in granulosa cells of the young normal and poor ovarian responder patients and elderly patients undergoing ovarian stimulation for IVF. METHODS: The main outcome measures granulosa cells telomere Length in the 3 study groups of patients undergoing IVF treatment in our center. 1) young normal responder patients (< 35 years); 2) young (< 35 years) poor ovarian responder patients; and 3) Elderly patients (40-45 years). Granulosa cells were obtained at the time of oocyte retrieval. Granulosa cells telomere length was assessed by absolute human telomere length quantification qPCR Assay. RESULTS: The telomere length of the young normal responder was significantly longer as compared to young poor ovarian responder (15.5 vs 9.6 KB, p < 0.001) and the elderly patients (15.5 vs 10.66 KB, p < 0.002). No significant difference was observed in the telomere length between the young poor ovarian responder and the elderly patients. CONCLUSIONS: Granulosa cells telomere length of the young normal responder was found to be significantly longer than young poor ovarian responder or elderly patients, highlighting the role of telomere length as a predictor, or contributor to poor oocyte yield following IVF treatment.

PURPOSE: We aimed to determine the factors associated with a successful trial of labor after cesarean (TOLAC) in the setting of preterm delivery of women with no prior vaginal delivery. METHODS: A retrospective cohort study conducted at two tertiary medical centers during 2010-2020, including all TOLACs with a single cesarean delivery and no prior vaginal delivery, delivering a singleton preterm newborn. Factors associated with successful vaginal delivery were examined by multivariable analysis. RESULTS: Of the 232 women with TOLAC who constituted the study cohort, 178 (76.7%) successfully delivered vaginally. Previous cesarean delivery characteristics did not differ between study groups. Maternal characteristics did not differ between TOLAC success and failure groups. The median gestational age at delivery was 35 3/7 weeks (IQR 34 0/7-36 0/7). The rate of epidural analgesia administration was higher in the TOLAC success group (54.5% vs. 35%, p = 0.013). Preterm premature rupture of membranes (PPROM) rate was lower in the TOLAC success group (53.9% vs. 83%, p < 0.001). The rate of induction of labor did not differ between TOLAC success and TOLAC failure groups. There were no cases of uterine rupture. In a multivariable logistic regression analysis, PPROM was the only independent factor associated with TOLAC success [adjusted OR (95% CI) 0.29 (0.10-0.83), p = 0.030]. CONCLUSION: TOLAC in preterm deliveries among women with no prior vaginal delivery is safe, has a high success rate and PPROM is the only negatively associated predictor.

KEY MESSAGE: Among SARS-CoV-2-infected mothers, vaginal delivery rates were high and associated with favorable outcomes with no cases of neonatal COVID-19. PURPOSE: To investigate the mode of delivery and its impact on immediate neonatal outcome in SARS-CoV-2-infected women. METHODS: A prospective study following pregnant women diagnosed with COVID-19 who delivered between March 15th and July 4th in seven university affiliated hospitals in Israel. RESULTS: A total of 52 women with a confirmed diagnosis of COVID-19 delivered in the participating centers during the study period. The median gestational age at the time of delivery was 38 weeks, with 16 (30.8%) cases complicated by spontaneous preterm birth. Forty-three women (82.7%) underwent a trial of labor. The remaining 9 women underwent pre-labor cesarean delivery mostly due to obstetric indications, whereas one woman with a critical COVID-19 course underwent urgent cesarean delivery due to maternal deterioration. Among those who underwent a trial of labor (n = 43), 39 (90.7%) delivered vaginally, whereas 4 (9.3%) cases resulted in cesarean delivery. Neonatal RT-PCR nasopharyngeal swabs tested negative in all cases, and none of the infants developed pneumonia. No maternal and neonatal deaths were encountered. CONCLUSIONS: In this prospective study among SARS-CoV-2-infected mothers, vaginal delivery rates were high and associated with favorable outcomes with no cases of neonatal COVID-19. Our findings underscore that delivery management among SARS-CoV-2-infected mothers should be based on obstetric indications and may potentially reduce the high rates of cesarean delivery previously reported in this setting.

RESEARCH QUESTION: Does fetal reduction of triplet pregnancies to singleton result in superior obstetric and neonatal outcomes compared with triplets reduced to twins? DESIGN: A historical cohort study including 285 trichorionic and dichorionic triplet pregnancies that underwent abdominal fetal reduction at 11-14 weeks in a single tertiary referral centre. The study population comprised two groups: reduction to twins (nâ¯=â¯223) and singletons (nâ¯=â¯62). Main outcome measures were rates of pregnancy complications, preterm delivery and neonatal outcomes. Non-parametric statistical methods were employed. RESULTS: Triplet pregnancies reduced to twins delivered earlier (36 versus 39 weeks, P < 0.001) with higher prevalence of Caesarean section (71.1% versus 32.2%, P < 0.001) compared with triplets reduced to singletons. Preterm delivery rates were significantly higher in twins compared with singletons prior to 37 weeks (56.9% versus 13.6%, P < 0.001), 34 weeks (20.2% versus 3.4%, Pâ¯=â¯0.002) and 32 weeks (9.6% versus 0%, Pâ¯=â¯0.01). No significant difference was found in the rate of pregnancy loss before 24 weeks (1.3% in twins versus 4.8% in singletons, Pâ¯=â¯0.12) or in the rate of intrauterine fetal death after 24 weeks (0.4% versus 0%, Pâ¯=â¯1.0). Both groups had comparable obstetrical complications and neonatal outcomes, except for higher rates of neonatal intensive care unit admission in twins (31.9% versus 6.8%, P < 0.001). CONCLUSIONS: Reduction of triplets to singletons rather than twins resulted in superior obstetric outcomes without increasing the procedure-related complications. However, because the rate of extreme prematurity in pregnancies reduced to twins was low, the overall outcome of those pregnancies was favourable. Therefore, the option of reduction to singletons should be considered in cases where the risk of prematurity seems exceptionally high.

KEY MESSAGE: Laboratory characteristics of SARS-CoV-2 infection did not differ between pregnant and non-pregnant women. A trend of lower lymphocyte count was observed in the pregnant women group PURPOSE: Laboratory abnormalities, which characterize SARS-CoV-2 infection have been identified, nevertheless, data concerning laboratory characteristics of pregnant women with SARS-CoV-2 are limited. The aim of this study is to evaluate the laboratory characteristics of pregnant compared to non-pregnant women with SARS-CoV-2 infection. METHODS: A retrospective cohort study of all pregnant women with SARS-CoV-2 who were examined at the obstetric emergency room in a tertiary medical center between March and April 2020. Patients were compared with non-pregnant women with SARS-CoV-2 matched by age, who were examined at the general emergency room during the study period. All patients were confirmed for SARS-CoV-2 on admission. Clinical characteristics and laboratory results were compared between the groups. RESULTS: Study group included 11 pregnant women with SARS-CoV-2, who were compared to 25 non-pregnant controls. Respiratory complaints were the most frequent reason for emergency room visit, and were reported in 54.5% and 80.0% of the pregnant and control groups, respectively (p = 0.12). White blood cells, hemoglobin, platelets, and liver enzymes counts were within the normal range in both groups. Lyphocytopenia was observed in 45.5% and 32% of the pregnant and control groups, respectively (p = 0.44). The relative lymphocyte count to WBC was significantly reduced in the pregnant group compared to the controls [13.6% (4.5-19.3) vs. 26.5% (15.7-29.9); p = 0.003]. C-reactive protein [20(5-41) vs. 14 (2-52) mg/dL; p = 0.81] levels were elevated in both groups but without significant difference between them. CONCLUSION: Laboratory characteristics of SARS-CoV-2 infection did not differ between pregnant and non-pregnant women, although a trend of lower lymphocyte count was observed in the pregnant women group.

OBJECTIVE: The aim of this study was to evaluate obstetric outcomes in relation to the extent of donor sperm exposure with and without egg donation. MATERIALS AND METHODS: This is a retrospective cohort study in a single tertiary care center. All women with a singleton pregnancy who conceived following sperm donation (SD) were included. Obstetrics and neonatal outcomes for pregnancies following single SD were compared with pregnancies following repeat SD from the same donor. In a secondary analysis, we compared pregnancy outcomes among three modes of assisted reproductive technology (intrauterine insemination [IUI-SD], in vitro fertilization [IVF-SD], and IVF sperm + egg donation [IVF-SD + ED]). RESULTS: A total of 706 pregnant women met the inclusion criteria, 243 (34.4%) following the first SD and 463 (65.6%) following repeat donations. Compared with repeat SDs, single donation was not associated with higher rates of preterm delivery (12.8 vs. 12.7%, respectively, p = 0.99), preeclampsia (7.0 vs. 6.9%, p = 0.999), and intrauterine growth restriction (4.1 vs. 3.9%, p = 0.88). Pregnancies following IVF-SD + ED had increased risk for preeclampsia (adjusted odds ratio [AOR], 3.1; 95% confidence interval [CI], 1.5-6.6), preterm labor (AOR, 2.4; 95% CI, 1.1-5.4), and cesarean section (AOR, 2.1; 95% CI, 1.0-4.3) compared with IUI-SD and IVF-SD. CONCLUSION: The extent of donor sperm exposure did not correlate with obstetrics complications, but double gamete donation was associated with increased risk for preeclampsia, preterm labor, and cesarean section.

OBJECTIVE: To describe outcomes of expectant management (EM) versus methotrexate (MTX) treatment in tubal pregnancies with pretreatment human chorionic gonadotropin (hCG) less than 2000 mIU/mL. METHODS: This retrospective cohort from two tertiary hospitals included women with confirmed tubal pregnancies and pretreatment hCG <2000 mIU/mL. Exclusion criteria were unrecorded pregnancy site, unconfirmed diagnosis, and surgical treatment upon diagnosis. The primary outcome was eventual rate of surgical treatment. RESULTS: Between December 2009 and June 2021, 545 of 2114 (25.8%) women diagnosed with a tubal pregnancy met our inclusion criteria. We compared women who underwent EM (N = 201) with women who received MTX (N = 344). All women in the EM group had a declining trend of hCG. The MTX group had higher pretreatment hCG and higher rates of yolk sac or embryo presence on ultrasound. Eventual surgical treatment rate was higher in the MTX group compared with the EM group (39 [11.3%] vs. 9 [4.5%], P = 0.006), with no difference in the treatment failure rate or tubal rupture rate. In a subgroup analysis of women with pretreatment hCG between 1000 and 2000 mIU/mL, eventual surgical treatment, treatment failure, and tubal rupture rates did not differ between groups. Logistic regression analysis revealed that eventual surgical treatment was independently associated with hCG levels less than 1000 mIU/mL (adjusted odds ratio [aOR] 0.28, 95% confidence interval [CI] 0.14-0.56) and endometriosis (aOR 9.20, 95% CI 3.55-23.81). CONCLUSION: Expectant management of tubal pregnancies with pretreatment hCG levels less than 2000 mIU/mL and even between 1000 and 2000 mIU/mL and with a declining trend of hCG demonstrated lower or comparable rates of eventual surgical treatment, when compared with MTX treatment.

OBJECTIVE: To identify risk factors for readmission following methotrexate treatment for tubal pregnancy. METHODS: A retrospective study undertaken in two tertiary medical centers, including all individuals with medically treated tubal pregnancy (N = 511), between December 2009 and June 2021. Individuals with and without readmission following methotrexate treatment were compared. The primary outcome was the readmission rate. Secondary outcomes included the rate of post-discharge gynecological emergency department visits, tubal rupture rate, and the eventual need for surgical treatment. RESULTS: Readmission following methotrexate treatment occurred in 224/511 patients (43.8%). Most readmissions were due to abdominal pain or suspicion of treatment failure. Readmitted individuals were more likely to have a history of pelvic inflammatory disease and pretreatment serum human chorionic gonadotropin (hCG) >2000 mIU/mL. Both factors remained significantly associated with higher readmission rates in a logistic regression analysis (adjusted odds ratio [OR] 6.28, 95% confidence interval [CI] 1.30-30.45, and adjusted OR 2.73, 95% CI 1.83-4.07, respectively) after adjustment for age, endometriosis, tubal pathology, abdominal pain, and presence of yolk sac or embryo at diagnosis. A dose-dependent association was observed between pretreatment serum hCG levels and readmission rate (P < 0.001). Pretreatment hCG levels were also associated with tubal rupture and the eventual need for surgical treatment (P < 0.001 for both). A prediction model using hCG was not sufficiently accurate to predict readmission risk. CONCLUSION: Readmission following methotrexate treatment for tubal pregnancy was independently associated with previous pelvic inflammatory disease and pretreatment serum hCG levels. The latter was also associated with surgical intervention rate.

OBJECTIVE: To evaluate whether the risk of fetal malpresentation following mechanical labor induction could be accurately predicted. METHODS: A retrospective study, including all individuals who underwent labor induction at a single tertiary medical center between March 2011 and May 2021. Cohorts of pharmacological (n = 16 480) and mechanical labor induction (n = 6864) were compared, determining malpresentation rate following induction. Individuals with and without fetal malpresentation following balloon placement were compared. RESULTS: Malpresentation following balloon placement occurred in 62 patients (0.9%). Those patients with malpresentation following balloon placement were older, had higher body mass index during labor, higher parity, polyhydramnios, higher fetal station at the start of labor induction, and delivered at an earlier gestational age compared with control patients. The combined presence of at least three of these risk factors was associated with a malpresentation rate of 8% (7/88) and yielded a positive likelihood ratio of 9.48 (95% confidence interval [CI] 4.57-19.7). A prediction model using these variables was not sufficiently accurate to predict the risk of malpresentation following balloon labor induction; a calculated area under the generated receiver operating characteristic curve was 0.78 (95% CI 0.72-0.84). CONCLUSION: Several risk factors were identified for malpresentation following mechanical labor induction, although these were of low predictive value.

OBJECTIVE: To evaluate the outcome of pelvic inflammatory disease (PID) in patients with endometriosis with and without ovarian endometrioma. DESIGN: A retrospective cohort study. SETTING: A single university-affiliated tertiary center. PATIENT(S): A total of 116 patients with endometriosis hospitalized because of PID between the years 2011-2021. Fifty-nine patients with an ovarian endometrioma component were compared with 57 patients with endometriosis without endometrioma. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): The primary outcome was severe PID defined as the need for surgical intervention or drainage. Secondary outcomes included tubo-ovarian abscess, number of hospitalization days, a positive cervical bacterial culture or urine sexually trasmitted disease polymerase chain reaction (STD PCR) test, and readmission because of partially treated or relapsing PID. RESULT(S): PID in patients with endometrioma was found less likely to respond to antibiotic treatment with increased risk for surgical intervention or drainage compared with endometriosis patients without endometrioma (adjusted odds ratio, 3.5; confidence interval, 1.25-9.87). On admission, patients with endometrioma were older (26.5 vs. 31.0) and less likely to have an intrauterine device (19.3% vs. 5.1%) compared with patients without endometrioma. The rate of the tubo-ovarian abscess (52.5% vs. 19.3%) was significantly higher in patients with endometrioma. Readmission rate, positive bacterial culture, and hospitalization duration were higher in the endometrioma group; however, they did not reach statistical significance. Recent oocyte retrieval and patient's age were not associated with an increased risk of severe PID. CONCLUSION(S): Endometrioma patients with PID are less likely to respond to antibiotic treatment and present a higher risk for surgical intervention.

We aimed at studying isolated Fallopian tube torsion (IFTT) in a relatively large cohort of women and to evaluate different features of IFTT in comparison to a large cohort of women with non-IFTT adnexal torsion (NIAT). This was a retrospective cohort study. We included women with surgically confirmed ovarian and/or Fallopian tube torsion between March 2011 and June 2020. Fifty-four cases of IFTT were surgically confirmed during the study period and were compared to 422 surgically confirmed NIAT. The rate of controlled ovarian hyperstimulation treatments, current pregnancy, and vomiting was lower in the IFTT group compared with the NIAT group. Cervical tenderness and vaginal discharge were more common in the IFTT group. Oedematous and enlarged ovaries were less common in the IFTT group. In multivariate regression analysis, the following factors were independently associated with IFTT: (i) vaginal discharge [adjusted odds ratio (aOR) 95% CI 8.16, 1.98-33.55]; (ii) cervical motion tenderness (aOR 95% CI 2.71, 1.01-7.29); (iii) fertility treatments (aOR 95% CI 0.26, 0.70-0.77); (iv) previous abdominal surgery (aOR 95% CI 0.46, 0.22-0.96); (v) vomiting (aOR 95% CI 0.38, 0.19-0.76); and (vi) enlarged ovary (aOR 95% CI 0.34, 0.18-0.65). In conclusion, we have identified factors positively and negatively associated with IFTT in a large cohort of women with adnexal torsion.
RESUMEN
Objective: The objective of this study is to assess the delivery outcomes of neonates with congenital heart defects (CHD), and to explore the effect of prenatal diagnosis on these outcomes. Methods: A retrospective study including singleton deliveries between 2011 and 2020. All singleton neonates delivered at >24 weeks of gestation were included in this study. Fetuses with known prenatal anomalies other than CHD were excluded from this study. Pregnancy and neonatal outcomes were analyzed. A comparison was made between pregnancies with CHD and controls; and between pregnancies with prenatal diagnosis of CHD and postnatal diagnosis of CHD. Results: A total of 1598 neonates with CHD (688, 43.1% diagnosed prenatally) comprised the study group, compared to 85,576 singleton controls. Pregnancies with CHD had significantly increased BMI before pregnancy, suffered more from diabetes and chronic hypertension, had more inductions of labor, and had more cesarean deliveries (CD) including both elective CD and urgent CD due to non-reassuring fetal monitor (NRFHR) (OR = 1.75; 95%CI 1.45−2.14). Prenatal diagnosis of CHD is associated with a significant increased rate of induction of labor compared to postnatal diagnosis of CHD (OR = 1.59; 95% CI 1.15−2.22), but did not affect the mode of delivery including the rate of CD and CD due to non-reassuring fetal heart rate (NRFHR). Gestational age at birth and birthweight were significantly lower in pregnancies with CHD compared to controls, with no difference between prenatal to postnatal diagnosis of the anomaly. Neonates with CHD had a higher incidence of hypoxic ischemic encephalopathy and seizures compared to controls without any impact by prenatal diagnosis. Conclusion: Prenatal diagnosis of CHD is associated with an increased rate of induction of labor, with no increased rate of CD and CD due to NRFHR. The 5-min Apgar score is lower in pregnancies with postnatal diagnosis of CHD.
