ABSTRACT

Background: Postpartum hemorrhage (PPH) represents one of the principal causes of maternal mortality and morbidity worldwide. Uterine balloon tamponade (UBT) is recommended for the treatment of postpartum hemorrhage due to uterine atony in women who do not respond to pharmacological first-line treatment. The success of UBT in bleeding control is related to the correct positioning of the device, since incorrect insertion can be associated with ineffectiveness and requires time-consuming repositioning maneuvers, with a further increase in blood loss. The use of ultrasound (US) during UBT may increase the success rate by preventing wrong positioning. This study aims to demonstrate the role of US guidance during UBT and to assess whether US guidance can ease positioning and reduce insertion times, preventing additional repositioning maneuvers, in comparison with a US check carried out after balloon insertion. Methods: This was a retrospective study including 370 women who underwent vaginal delivery, had PPH caused by uterine atony and required UBT at Sant'Anna Hospital from 2015 to 2019. The exclusion criteria were an abnormal placental site, vaginal or cervical trauma, coagulation defects, uterine anomalies, previous postpartum hemorrhage and previous caesarean section. Included subjects were divided into two groups: the US-guided group (n = 200) underwent Bakri balloon positioning under US guidance, and the non-guided group (n = 170) received a US check only after balloon insertion. The primary outcome was the success rate of the procedure, expressed as the percentage of cases with bleeding control without the need for balloon repositioning; the secondary outcomes were the length of the procedure and some parameters related to blood loss. Results: The success rate was 99% for the US-guided group vs. 86% for the non-guided group. None of the patients required hysterectomy. In the US-guided group with respect to the non-guided group, we observed a significant reduction in blood loss (1100 ± 450 vs. 1500 ± 600 mL; p < 0.001), Δhemoglobin level (1.8 ± 1.1 vs. 2.7 ± 2.0 g/dL, p < 0.001) and time required for the procedure (8 vs. 13 min, p < 0.001). Conclusions: Our data suggest that the use of US guidance for placement of UBT was associated with reduced need for balloon repositioning, lower blood loss, and faster resolution of postpartum hemorrhage.

ABSTRACT

BACKGROUND: Sentinel lymph node biopsy represents an alternative to pelvic lymphadenectomy for lymph node staging of early-stage cervical carcinoma, but prospective evidence on long-term oncological safety of sentinel lymph node biopsy alone versus pelvic lymphadenectomy is missing. OBJECTIVE: To investigate, with this meta-analysis, the impact of sentinel lymph node biopsy alone versus pelvic lymphadenectomy on survival for patients with early-stage cervical cancer. METHODS: A systematic literature review was performed. We excluded studies in which pelvic lymphadenectomy was systematically performed after every sentinel lymph node biopsy, including only articles where pelvic lymphadenectomy was performed because sentinel lymph node biopsy was not conclusive. A meta-analysis was carried out combining 5-year disease-free survival and overall survival rates with a random and fixed effect model. Heterogeneity was tested using the Cochran Χ2 test and quantified with Higgins information I2. RESULTS: The search of databases and registers found 927 items and six articles (two retrospective and four prospective). The median time of follow-up was 34.8 months (range 13-53). Overall common effect disease-free survival was 98% while random effect disease-free survival was 94%. Overall heterogeneity was 77%. A subgroup analysis was applied, dividing studies into one group including sentinel lymph node biopsy negative data only (common effect disease-free survival 91%; random effect disease-free survival 90%), and one group with a negative and positive sentinel lymph node biopsy (common effect disease-free survival 98%; random effect disease-free survival 96%). In the analysis of overall survival, positive and negative sentinel lymph node biopsy cases were examined together (common and random effect overall survival 99%). Ultrastaging did not affect disease-free survival (common and random effect disease-free survival 92% in the ultrastaging group vs common effect disease-free survival 99% and random effect disease-free survival 96% in the non-ultrastaging group). CONCLUSIONS: Both 5-year disease-free survival and overall survival rate after sentinel lymph node biopsy alone are higher than 90% and do not differ from pelvic lymphadenectomy survival data. Ultrastaging did not impact survival.

ABSTRACT

INTRODUCTION: In patients affected by epithelial ovarian cancer (EOC) complete cytoreduction (CC) has been associated with higher survival outcomes. Artificial intelligence (AI) systems have proved clinical benefice in different areas of healthcare. OBJECTIVE: To systematically assemble and analyze the available literature on the use of AI in patients affected by EOC to evaluate its applicability to predict CC compared to traditional statistics. MATERIAL AND METHODS: Data search was carried out through PubMed, Scopus, Ovid MEDLINE, Cochrane Library, EMBASE, international congresses and clinical trials. The main search terms were: Artificial Intelligence AND surgery/cytoreduction AND ovarian cancer. Two authors independently performed the search by October 2022 and evaluated the eligibility criteria. Studies were included when data about Artificial Intelligence and methodological data were detailed. RESULTS: A total of 1899 cases were analyzed. Survival data were reported in 2 articles: 92% of 5-years overall survival (OS) and 73% of 2-years OS. The median area under the curve (AUC) resulted 0,62. The model accuracy for surgical resection reported in two articles reported was 77,7% and 65,8% respectively while the median AUC was 0,81. On average 8 variables were inserted in the algorithms. The most used parameters were age and Ca125. DISCUSSION: AI revealed greater accuracy compared against the logistic regression models data. Survival predictive accuracy and AUC were lower for advanced ovarian cancers. One study analyzed the importance of factors predicting CC in recurrent epithelial ovarian cancer and disease free interval, retroperitoneal recurrence, residual disease at primary surgery and stage represented the main influencing factors. Surgical Complexity Scores resulted to be more useful in the algorithms than pre-operating imaging. CONCLUSION: AI showed better prognostic accuracy if compared to conventional algorithms. However further studies are needed to compare the impact of different AI methods and variables and to provide survival informations.

ABSTRACT

Background. Positron emission tomography (PET) has proven clinical utility both in the initial and relapse staging phase, but this technique is controversial during pregnancy. The objective of this review is to provide a compendium of available information on the use of PET during pregnancy. Materials and methods. A systematic literature review was conducted from 1 January 2004 until 20 May 2021. A total of 4 small series and 9 case reports consisting of 25 cases were selected. Results. During the first trimester, the fetus is most sensitive to ionization damage, so lower doses are recommended (2.6E-02 mGy/MBq). Fetal-effective doses are higher in this period and the average fetal dose (4.06 ± 3.22 mGy) remains significantly below the threshold for deterministic effects. During the second and third trimesters, recommended doses are higher (1.4E-02 mGy/MBq at 6 months, and 6.9E-03 mGy/MBq at 9 months of gestation). 18F-FDG activity was distributed to the whole fetus with a prevalence of myocardial tissue in seven cases. The use of special precautions, such as PET-magnetic resonance (MR) and urinary bladder catheterization, reduces the amount of radioactive tracer. Breastfeeding interruption is not recommended. Conclusions. 18F-FDG PET is not contraindicated in pregnancy, but multidisciplinary discussion is necessary and strict precautions are recommended.

ABSTRACT

Background and Aims: Aetiopathogenesis of chorioangioma is already unknown. Among the risk factors, hypoxia, environmental and genetic factors are believed to induce the overexpression of angiogenic cytokines promoting vascular proliferation. We reported a case of prenatally diagnosed 67 mm-wide placental chorioangioma, which occurred at 32 weeks of gestational age, infarcted, and followed by the onset of a second infarcted chorioangioma at 35 weeks of gestational age. Besides, we discussed the hypothesis of chorioangioma aetiopathogenesis and behavior through a literature summary. Methods: We carried out a literature search of chorioangioma cases without a time interval. Therefore, we carried out a literature summary on chorioangioma risk factors and etiology, by selecting articles within a time interval from 1995 to 2021. Results: This is the first case of two consecutive chorioangiomas in the same pregnancy published in the literature. We found a possible genetic predisposition in women developing chorioangioma while infarction may be related to the abnormal structure of tumor vessels. The onset of a second lesion could reflect hypoxic stimuli following infarction and involves hypoxia-induced factor-1alpha, vascular endothelial growth factor, transforming growth factor-beta, and soluble Fms-like tyrosine kinase-1 pathways. Chorangiosis can be coexistent and may reflect a mutual etiology in susceptible individuals. Conclusion: In a predisposed placenta, that previously generated a chorioangioma, infarction of the chorioangioma should not represent a sign for pregnancy termination, but a marker for closer monitoring to early detect the possible onset of a second chorioangioma and a higher risk of umbilical cord thrombosis.

ABSTRACT

Purpose: Depressive disorders are related to obstetrical and neonatal complications. The purpose of this study is to evaluate the outcomes of pregnancy in women suffering from depressive disorders, who are treated or not treated with pharmacotherapy during pregnancy. Methods: The maternal and neonatal outcomes of 281 pregnant women with depressive disorders (D group-DG), who delivered their babies at Sant'Anna Hospital of Turin, were compared with those of a control group of 200 depression-free, healthy, pregnant women, who were matched for maternal age (C group-CG). Of the depressed patients, those who received pharmacotherapy during pregnancy (DG-Tr, n = 199, 70.8%) were compared with those who did not (DG-Untr, n = 82, 29.2%). The comparisons were performed using χ2 tests for categorical variables and ANOVA for continuous variables. A linear regression analysis was run to examine the association between APGAR scores at 5 min and certain clinical variables. Results: The women in DG showed higher rates of cesarean section, preterm delivery, induction of labor and SGA babies, and low neonatal weights and 5-min APGAR scores, compared to the untreated patients. Those treated with psychotropic drugs showed lower rates of cesarean section, but lower 5-min APGAR scores, compared to those who were untreated. However, after controlling for confounding variables, the 5-min APGAR scores were linearly associated with neonatal weight and not with the use of psychotropic treatment. No significant differences were observed between the treated and untreated women, regarding the rates of preterm delivery, induction of labor, SGA and low neonatal weight. Conclusion: In pregnant patients with depressive disorders, poorer outcomes are expected vs. healthy controls. Pharmacological treatment is associated with a reduced rate of cesarean section, without inducing other complications for the mother and the newborn.

ABSTRACT

BACKGROUND: To date, no research has focused on the sonographic quantification of the degree of flexion of the fetal head in relation to the labor outcome in women with protracted active phase of labor. OBJECTIVE: This study aimed to assess the relationship between the transabdominal sonographic indices of fetal head flexion and the mode of delivery in women with protracted active phase of labor. STUDY DESIGN: Prospective evaluation of women with protracted active phase of labor recruited across 3 tertiary maternity units. Eligible cases were submitted to transabdominal ultrasound for the evaluation of the fetal head position and flexion, which was measured by means of the occiput-spine angle in fetuses in nonocciput posterior position and by means of the chin-to-chest angle in fetuses in occiput posterior position. The occiput-spine angle and the chin-to-chest angle were compared between women who had vaginal delivery and those who had cesarean delivery. Cases where obstetrical intervention was performed solely based on suspected fetal distress were excluded. RESULTS: A total of 129 women were included, of whom 43 (33.3%) had occiput posterior position. Spontaneous vaginal delivery, instrumental delivery, and cesarean delivery were recorded in 66 (51.2%), 17 (13.1%), and 46 (35.7%) cases, respectively. A wider occiput-spine angle was measured in women who had vaginal delivery compared with those submitted to cesarean delivery owing to labor dystocia (126±14 vs 115±24; P<.01). At the receiver operating characteristic curve, the area under the curve was 0.675 (95% confidence interval, 0.538-0.812; P<.01), and the optimal occiput-spine angle cutoff value discriminating between cases of vaginal delivery and those delivered by cesarean delivery was 109°. A narrower chin-to-chest angle was measured in cases who had vaginal delivery compared with those undergoing cesarean delivery (27±33 vs 56±28 degrees; P<.01). The area under the curve of the chin-to-chest angle in relation to the mode of delivery was 0.758 (95% confidence interval, 0.612-0.904; P<.01), and the optimal cutoff value discriminating between vaginal delivery and cesarean delivery was 33.0°. CONCLUSION: In women with protracted active phase of labor, the sonographic demonstration of fetal head deflexion in occiput posterior and in nonocciput posterior fetuses is associated with an increased incidence of cesarean delivery owing to labor dystocia. Such findings suggest that intrapartum ultrasound may contribute in the categorization of the etiology of labor dystocia.

ABSTRACT

INTRODUCTION: At present there is no predictive value univocally associated with the success of chemotherapy. Biomarkers produced by ovarian cancer (HE4 and Ca125) could have a good prognostic significance. The aim of this study is to prove the ability of biomarkers to identify patients with the highest risk of non-optimal response during the chemotherapy, and to predict which patients will most likely develop recurrence of disease. METHODS: We analyzed 78 patients with epithelial ovarian cancers who underwent surgery in the biennium 2016-2017. All the patients underwent chemotherapy after surgery or interval debulking surgery following neoadjuvant therapy. Serum levels of HE4 and Ca125 were measured at diagnosis and at each cycle of chemotherapy. We established the degree of response to the treatment by computed tomography scan, and the patients were followed up (median: 10 months). The parameters of progression-free survival and disease-free survival were related to serum levels of biomarkers. RESULTS: Both CA125 and HE4 values became negative at the fourth cycle in the patients with good response to chemotherapy. HE4 increased earlier than Ca125. The parameters that best correlated with a long progression-free survival were: negativization of the marker after the third cycle of chemotherapy (HE4: odds ratio (OR) 5.5; Ca125: OR 9.1) and biomarker serum levels lower than the mean value in the affected population at the time of diagnosis (HE4: OR 3.4; Ca125: OR 3.7). CONCLUSIONS: We can conclude that the monitoring of HE4 and Ca125 during chemotherapy, especially at the third cycle, is recommended, because their variation is a good prognostic factor.

ABSTRACT

Importance: The active-during-pregnancy-cancer (ADPC) is a condition that complicates the 0.1% of pregnancies. Abortion, preterm delivery and cesarean section (CS) are common attitudes for these patients, because of scarcity of evidence-based studies. Not-active-during-pregnancy-cancer (NADPC) is an increasing medical problem. The fertility of young girls survived to neoplasia is significantly lower compared to general population and there are increased rates of low birth weight and preterm birth.Objective: To analyze the impact that the pregnancy-related neoplastic disease has on management of deliveries in the decade 2006-2015.Material and methods: In this observational study, we collected obstetric and oncological data about 205 patients bearing a history of cancer related to pregnancy between January 2006 and September 2016 from Sant'Anna Hospital database archive in Turin. The entire population was divided in 59 patients with ADPC and 146 patients with NADPC because it was cured before starting the gestation. Three ADPC and three NADPC patients who completed their pregnancy in the year 2016 were excluded from the 10 years 2006-2015 trends realization. All in situ and invasive cancers were considered.Results: In ADPC patients, we registered 3.4% miscarriage and 15.3% iatrogenic abortion. The type of delivery was vaginal (22%) and CS (59.3%). Induction of labor was 14.6%, elective CS was 68.8%: the indication for these procedures was 78.6% oncological. The average gestational age was 35.5 weeks. In NADPC patients, we registered 9.6% miscarriage and 8.2% iatrogenic abortion. The type of delivery was vaginal (43.2%) and CS (39%). Induction of labor was 11.7%, elective CS was 36.7%: the indication for these procedures was 77.5% obstetrical. The average gestational age was 38.3 weeks.Conclusions: Ten-year trends in ADPC and NADPC patients showed an increase of induced deliveries and a decrease in elective CS. We observed not significant reduction of gestational age and birth weight. A contemporary decrease of oncological indications for CS in the two populations was reported.

ABSTRACT

PURPOSE: To compare the performance of the algorithms proposed by the Fetal Medicine Foundation in 2012 and BCNatal in 2013 in an Italian population. METHODS: A multicentric prospective study was carried out which included pregnancies at 11-13 weeks' gestation from Jan 2014 through May 2017. Two previously published algorithms were used for the calculation of the "a priori" risk of preeclampsia (based on risk factors from medical history) in each individual. RESULTS: In a study population of 11,632 cases, 67 (0.6%) developed early preeclampsia and 211 (1.8%) developed late preeclampsia. The detection rates (95% CI) for early and late preeclampsia were 58.2% (45.5-70.2) vs. 41.8% (29.6-54.5) (p value < 0.05) and 44.1% (37.3-51.1) vs. 38% (31.3-44.8) (p value < 0.05) for the Fetal Medicine Foundation and BCNatal, respectively (at a 10% false positive rate). The associated risk was 1:226 and 1:198 (p value ns) for early PE, and 1:17 and 1:24 (p value ns) for late PE for the Fetal Medicine Foundation and BCNatal, respectively. CONCLUSIONS: The Fetal Medicine Foundation screening for preeclampsia at 11-13 weeks' gestation scored the highest detection rate for both early and late PE. At a fixed 10% false positive rate, the estimated "a priori" risks of both the Fetal Medicine Foundation and the BCNatal algorithms in an Italian population were quite similar, and both were reliable and consistent.
