Objective: To evaluate benefits of use of ureteral stents in association with cesarean hysterectomy in case of placenta accreta.Methods: This was a single center, cohort study. Clinical records of singleton pregnancies with placenta accreta who underwent cesarean hysterectomy were included in the study. For this study, pregnancies with diagnoses of placenta accreta, increta, or percreta were considered under the umbrella term of placenta accreta. For all women with placenta accreta, delivery was planned via cesarean hysterectomy at 340-356 weeks, without any attempt to remove the placenta. Reasons for earlier delivery included vaginal bleeding and spontaneous onset of labor. The primary outcome was the incidence of unintentional urinary tract injury. Outcomes were compared in a cohort of women who had planned the placement of ureteral stents and in those who did not.Results: Forty-four singleton gestations with confirmed placenta accreta at the time of cesarean hysterectomy were included in the study. Twenty-four (54.5%) of the included women had the placing of ureteral stents prior to cesarean, while 20 (45.5%) did not. At histological confirmation, most of them had placenta accreta (17/44, 38.6%), 14 placenta increta (31.8%), and 13 placenta percreta (29.6%). Urinary tract injuries occurred in eight cases (18.2%), six in the ureteral stents and two in the non-ureteral stents group (25 versus 10%; p = .21). All the injuries were bladder injuries, while no cases of ureteral injury were recorded. All injuries were recognized intraoperatively.Conclusion: In case of placenta accreta, the use of ureteral stents in association with cesarean hysterectomy does not reduce the risk of urinary tract injury.

Objective: To evaluate the effectiveness of antenatal intervention for the treatment of congenital lower urinary tract obstruction (LUTO) in improving perinatal survival and postnatal renal function.Methods: Electronic databases were searched from their inception until May 2018. Selection criteria included randomized controlled trials and nonrandomized studies including fetuses with ultrasound evidence of LUTO evaluating antenatal intervention for improving perinatal outcomes. Any type of antenatal bladder drainage technique was analyzed. The primary outcome was perinatal survival. The secondary outcome was postnatal survival with normal renal function. The summary measures were reported as summary odds ratio (OR) with 95% of confidence interval (CI).Results: Ten articles with a total of 355 fetuses were included in the meta-analysis. Inclusion criteria of the selected studies were singleton pregnancy with severe LUTO confirmed on detailed fetal ultrasound examination. Nine studies analyzed the efficacy of vesico-amniotic shunt performed in the second trimester. The overall estimate survival was higher in the vesico-amniotic shunt group compared to the conservative group (OR: 2.54, 95% CI: 1.14-5.67). 64/112 fetuses (57.1%) survived in the vesico-amniotic shunt group compared to 52/134 (38.8%) in the control group. Five studies reported on postnatal renal function between 6 months and 2 years. Rate of good postnatal renal function was higher in the vesico-amniotic shunt group compared to the conservative group (OR: 2.09, 95% CI: 0.74-5.9). Fetal cystoscopy was performed in only two included studies. Overall, 45 fetuses underwent fetal cystoscopy. The perinatal survival was higher in the cystoscopy group compared to the conservative management group (OR: 2.63, 95% CI: 1.07-6.47). Normal renal function was noted in 13/34 fetuses in the cystoscopy group versus 12/61 in the conservative management group at 6 months follow-up (OR: 1.75, 95% CI: 1.05-2.92)Conclusions: Antenatal bladder drainage appears to improve perinatal survival in cases of LUTO.

Objective: To evaluate whether intrapartum cardiotocography with computer analysis decreases the incidence of newborn metabolic acidosis or obstetric intervention when compared with visual analysis through a systematic review with meta-analysis of randomized controlled trials.Methods: The research was conducted using Medline, Embase, Web of Science, Scopus, ClinicalTrial.gov, Ovid and Cochrane Library as electronic databases from the inception of each database to May 2018. Selection criteria included randomized trial evaluating women with cephalic presentation at term or late preterm term during labor who were randomized to electronic fetal heart rate monitoring with either computer analysis (i.e. intervention group) or standard visual analysis (i.e. control group). Trials evaluating antenatal fetal heart rate monitoring in women not in labor were excluded. The primary outcome was incidence of newborn metabolic acidosis, defined as pH less than 7.05 and base deficit greater than 12 mmol/L. Secondary outcomes were mode of delivery, admission to neonatal intensive care unit, hypoxic-ischemic encephalopathy, and perinatal death. The summary measures were reported as relative risk (RR) with 95% confidence interval (CI).Results: Three randomized controlled trials (RCTs), including 54,492 participants, which met inclusion criteria for this meta-analysis, were analyzed. All the included trials enrolled women with cephalic presentation at term or late preterm. Women were randomized in the active first stage of labor and all of them received continuous cardiotocography (CTG) from randomization until delivery. Women who received continuous CTG during labor with computerized analysis had similar risk of newborn metabolic acidosis. No between group differences were found in the secondary outcomes.Conclusions: Compared with visual analysis, use of computer analysis of fetal monitoring signals during labor did not significantly reduce the rate of metabolic acidosis or obstetric intervention.

Several causes for primary ovarian insufficiency (POI) have been described, including iatrogenic and environmental factor, viral infections, chronic disease as well as genetic alterations. The aim of this review was to collect all the genetic mutations associated with non-syndromic POI. All studies, including gene screening, genome-wide study and assessing genetic mutations associated with POI, were included and analyzed in this systematic review. Syndromic POI and chromosomal abnormalities were not evaluated. Single gene perturbations, including genes on the X chromosome (such as BMP15, PGRMC1 and FMR1) and genes on autosomal chromosomes (such as GDF9, FIGLA, NOBOX, ESR1, FSHR and NANOS3) have a positive correlation with non-syndromic POI. Future strategies include linkage analysis of families with multiple affected members, array comparative genomic hybridization (CGH) for analysis of copy number variations, next generation sequencing technology and genome-wide data analysis. This review showed variability of the genetic factors associated with POI. These findings may help future genetic screening studies on large cohort of women. [ABSTRACT FROM AUTHOR]

Objectives: Monoamniotic twin pregnancies are at increased risk of perinatal complications, primarily owing to the risk of cord entanglement. There is no recommendation on whether such pregnancies should be managed in hospital or can be safely managed in an outpatient setting, and the timing of planned delivery is also a subject of debate. The aim of this study was to compare the perinatal outcomes of inpatient vs outpatient fetal surveillance approaches employed among 22 participating study centers, and to calculate the fetal and neonatal death rates according to gestational age, in non-anomalous monoamniotic twins from 26 weeks' gestation.Methods: The MONOMONO study was a multinational cohort study of consecutive women with monochorionic monoamniotic twin pregnancies, who were referred to 22 university hospitals in Italy, the USA, the UK and Spain, from January 2010 to January 2017. Only non-anomalous uncomplicated monoamniotic twin pregnancies with two live fetuses at 26 + 0 weeks' gestation were included in the study. In 10 of the centers, monoamniotic twins were managed routinely as inpatients, whereas in the other 12 centers they were managed routinely as outpatients. The primary outcome was intrauterine fetal death. We also planned to assess fetal and neonatal death rates according to gestational age per 1-week interval. Outcomes are presented as odds ratio (OR) with 95% CIs. The main outcome was analyzed using both standard logistic regression analysis, in which each fetus was treated as an independent unit, and a generalized mixed-model approach, with each twin pair treated as a cluster unit, considering that the outcome for a twin is not independent of that of its cotwin.Results: 195 consecutive pregnant women with a non-anomalous uncomplicated monoamniotic twin gestation (390 fetuses) were included. Of these, 75 (38.5%) were managed as inpatients and 120 (61.5%) as outpatients. The overall perinatal loss rate was 10.8% (42/390) with a peak fetal death rate of 4.3% (15/348) occurring at 29 weeks' gestation. There was no significant difference in mean gestational age at delivery (31 weeks), birth weight (∼1.6 kg), or emergency delivery rate between the inpatient and outpatient surveillance groups. Based on generalized mixed-model analysis, there was no statistically significant difference in fetal death rates between inpatient management commencing from around 26 weeks compared with outpatient surveillance protocols from 30 weeks (3.3% vs 10.8%; adjusted OR 0.21 (95% CI, 0.04-1.17)). Maternal length of stay in the hospital was 42.1 days in the inpatient group, and 7.4 days in the outpatient group (mean difference 34.70 days (95% CI, 31.36-38.04 days). From 32 + 0 to 36 + 6 weeks, no fetal or neonatal death in either group was recorded. 46 fetuses were delivered after 34 + 0 weeks, and none of them died in utero or within the first 28 days postpartum.Conclusion: In uncomplicated monoamniotic twins, inpatient surveillance is associated with similar fetal mortality as outpatient management. After 31 + 6 weeks, and up to 36 + 6 weeks, there were no intrauterine fetal deaths or neonatal deaths. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd. [ABSTRACT FROM AUTHOR]

Aim: Invasive cervical cancer is proceeded by a phase of preinvasive disease that is slow to progress and can be detected, treated, and collectively referred to as cervical intraepithelial neoplasia (CIN). Several excisional and ablative treatments for CIN have been studied, with loop electrosurgical excision procedure (LEEP) and cryotherapy being the two most commonly utilized. The objective of this systematic review and meta-analysis of randomized controlled trials (RCTs) was to compare the compare harms and benefits of LEEP versus cryotherapy in women with CIN. Methods: Electronic databases were searched from their inception until May 2018. We included all RCTs comparing cryotherapy versus LEEP in women with CIN. We included trials evaluating both HIV-seropositive and HIV-seronegative women. The primary outcome was the persistence of the disease at 6-month follow-up. Meta-analysis was performed using the random-effects model to produce summary treatment effects in terms of relative risk (RR) with 95% confidence interval (CI). Results: Four trials, including 1035 women with CIN, were identified as relevant and included in the meta-analysis. Women who received LEEP for CIN had a significantly lower persistence at 6-month follow-up biopsy (RR: 0.87, 95% CI: 0.76–0.99) and significantly lower recurrence at 12-month follow-up biopsy (RR: 0.91, 95% CI: 0.84–0.99) compared to those who received cryotherapy. No between-group differences were found in the complications rate, but the analyses were not powered for these outcomes. Conclusions: In women with CIN, treatment with LEEP was associated with a significantly lower risk of persistence disease at 6 months and recurrence disease at 12 months compared to treatment with cryotherapy.

Dear Editor, Preterm birth, defined as delivery before 37 weeks of gestation, is a major cause of perinatal morbidity and mortality (Depa and Gundabattula [1]). In summary, a multiple micronutrient supplementation with arginine (3 g/die), willow bark (320 mg/die), magnesium (1 g/die) and calcium (1 g/die) during pregnancy may reduce the incidence of preterm birth.
