Semen cryopreservation in men undergoing cancer treatment: a ten-year study.

BACKGROUND: The advancement of Assisted Reproductive Technologies and the improvement in sperm freezing made male fertility preservation widely available. This study aims to evaluate the impact of cancer diseases on semen parameters before cryopreservation and the reproductive outcomes of patients who have thawed their semen samples. METHODS: An observational, cohort study was conducted on cancer patients submitted to fertility preservation in AUSL-IRCCS of Reggio Emilia between 2007 and 2018. Semen samples were collected before cancer treatments, analyzed and frozen by rapid freezing. On request, these samples were thawed for Assisted Reproductive Technologies procedures. Semen parameters were compared between testicular versus other cancers. RESULTS: We included 329 patients with a successful cryopreservation in 94.5% of cases. Testicular cancer was associated with lower sperm volumes (P=0.041) and lower total sperm concentration (P=0.009) compared to other cancers. No difference was observed about sperm motility and morphology, while oligozoospermia was significantly more frequent in men with testicular cancer (P<0.001). In our cohort, the 8.4% of patients thawed their samples; the usage rate and the embryo transfer rate were significantly higher (P<0.05) among those with a testicular cancer, while pregnancy and livebirth rates did not differ. CONCLUSIONS: Male fertility preservation is feasible, easy to be performed, non-invasive and does not delay cancer treatments. Men affected by testicular cancer had worse semen parameters at cryopreservation but pregnancy and livebirth rates were similar to those achieved by men with other cancers and similar to those achieved with fresh sperm.

How adenomyosis changes throughout pregnancy: A retrospective cohort study.

OBJECTIVE: To study how adenomyosis changes during pregnancy and to possibly correlate these changes to maternal and fetal outcomes. METHODS: Retrospective exploratory cohort study including 254 women with a pre-conceptional/first-trimester scan to document adenomyosis and known obstetric outcome. If visible, adenomyosis signs were documented in each trimester and postpartum. Mann-Whitney U tests or χ2 tests were used for continuous and categorical variables, respectively. RESULTS: A globular uterus was reported in 79% (n = 52) of women with adenomyosis in the first trimester, in 38% (n = 20) and 2% (n = 1) of women in the second and third trimesters, respectively, and postpartum in 77% (n = 34) of women. Asymmetrical thickening (n = 20, 30%) and cysts (n = 15, 23%) were only visible in 1st trimester. Adenomyosis was associated with miscarriage (odds ratio [OR] 5.9, 95% confidence interval [CI] 2.4-14.9, P < 0.001) also in normal conception only (OR 5.1, 95% CI 1.8-14.2, P = 0.002) or adjusting for maternal age (adjusted OR 5.9, 95% CI 2.3-15.2, P < 0.001). Gestational age at delivery was lower in adenomyosis (P = 0.004); the cesarean section rate was higher than in controls (OR 2.5, 95% CI 1.3-4.8, P = 0.007) also adjusting for age (adjusted OR 2.07, 95% CI 1.06-4.08, P = 0.035). CONCLUSIONS: Signs of adenomyosis were visible but progressively disappeared in pregnancy; adenomyosis was associated with an increased risk of early miscarriage. Prospective studies are needed to confirm our results.

Prelabour rupture of the membranes at term: antibiotic overuse in Italy.

BACKGROUND: The proper management of women with premature rupture of membrane (PROM) and not spontaneously entering in labour remains controversial. The aim of this study was to identify the current management for women with PROM at term according to the Group B Streptococcus (GBS) status across different Italian hospitals. METHODS: Anonymous online survey evaluating: the current practice of women with PROM in terms of management (expectant management vs. induction of labour) and antibiotic prophylaxis according to GBS status. RESULTS: In case of negative GBS status, the 82.4% of respondents wait until 24 hours before labour induction. Antibiotics are administered for prophylaxis in 35.3%, 27.5% and 2% at 18, 12 and 24 hours respectively. The remaining 35.3% of respondents are divided between those using antibiotics only with signs of infections or according to different risk factors (i.e. meconium-stained amniotic fluid or suspected infection). Neonates born from a mother with negative GBS status almost never (90.2%) receive prophylactic antibiotics. In case of positive GBS status, induction is started as soon as possible by 49.1% of respondents; the remnants choose to wait 6 (15.7%), 12 (17.6%), 18 (3.9%) and 24 (13.7%) hours. Antibiotics are administered as soon as possible by 78.4% of clinicians. In the neonates, 51% of neonatologist administer antibiotics upon clinical indications (suspected sepsis); 15.7% use antibiotics routinely or with a short interval between maternal antibiotics and delivery (17.6%). CONCLUSIONS: The management after PROM is highly heterogeneous with an inappropriate extension of antibiotic prophylaxis in cases with negative GBS status.

Complete hydatidiform mole in higher-order multiple pregnancies.

Molar degeneration of the trophoblast is a rare, yet possible, complication of pregnancies. Complete hydatidiform mole is the most common histological type among all trophoblastic tumors and it is the result of the fertilization of an empty oocyte from two sperms or by one sperm that then duplicates. Complete mole is characterized by hydropic degeneration of abnormal chorionic villi, diffused trophoblast hyperplasia and the absence of identifiable embryonic or fetal tissue; the hyperplastic trophoblast justifies the common finding of high serum beta HCG levels. Twin molar pregnancy is an uncommon obstetric event, and even less frequent are triplet/quadruplet molar pregnancies. We hereby report a case of a complete hydatidiform mole with two coexistent fetuses in a triplet pregnancy after in vitro fertilization procedure; the pregnancy ended with a therapeutic abortion. During the follow-up, the serum beta human chorionic gonadotropin concentration started to rise, and the diagnosis of post-molar gestational trophoblastic neoplasia was made and consequently methotrexate treatment was started. Due to the rarity of this condition, there are no specific guidelines for the management of multiple pregnancies complicated by complete hydatidiform mole. We therefore performed a review of the literature including all reported cases of triplets/quadruplets pregnancies complicated by complete mole of a fetus focusing on ultrasound diagnosis, treatment and outcomes of this rare and life-threatening condition.

Role of balloon tamponade during cesarean section in women with placenta previa: a systematic review and meta-analysis.

INTRODUCTION: To explore the role of balloon tamponade insertion in pregnancies complicated by placenta previa. EVIDENCE ACQUISITION: Medline, Embase and ClinicalTrials.gov databases were searched electronically on October 17. Inclusion criteria were women with placenta previa undergoing, compared to those not undergoing, balloon tamponade insertion at the time of the cesarean section (CS). The outcomes observed were total, intra- and post-operative estimated blood loss (EBL), need for blood transfusion, admission to intensive care unit (ICU), hysterectomy and additional surgical or medical procedures to achieve hemostasis. Results were reported as pooled odd ratios (OR) or mean difference (MD) according to the outcome investigated. EVIDENCE SYNTHESIS: Four studies (593 women) were included. Total EBL was significantly lower in women undergoing balloon tamponade insertion during CS compared to controls (MD: -556.3, 95% CI -496 to -617.0, P=0.001). Likewise, women undergoing balloon tamponade insertion had significantly lower intra- (MD: -699.8, 95% CI -766.1 to -633.5, P=0.001) and post-operative (MD: -1162 mL (95% CI -1211.1 to -1134.4, P<0.001) compared to women who did undergo such procedure. Furthermore, women undergoing balloon tamponade insertion had a significantly lower risk of requiring additional surgical (OR: 0.16, 95% CI 0.1-0.5, I2=0%; P=0.001) or medical (OR: 0.02, 95% CI 0.003-0.1, I2=0; P=0.001) procedures to achieve hemostasis. Conversely, there was no significant difference in either the need for blood transfusion (P=0.071), admission to ICU (P=0.459) or need for hysterectomy (P=0.312) between women undergoing, compared to those not undergoing, balloon tamponade insertion during CS for placenta previa. CONCLUSIONS: Elective balloon tamponade insertion at the time of CS for placenta previa seems to be associated with a lower EBL and a reduced risk of additional medical and surgical procedures to control hemostasis. Large and adequately powered randomized controlled trials are needed to validate these results and introduce elective balloon tamponade insertion at the time of CS for placenta previa in clinical practice.

Ultrasound screening for fetal anomalies in a single center: diagnostic performances twenty years after the Eurofetus Study.

PURPOSE: To establish the accuracy of ultrasound in detecting fetal anomalies looking at the concordance between prenatal and postnatal diagnosis. MATERIALS AND METHODS: Retrospective analysis of concordance between prenatal and postnatal/autoptic diagnosis of fetuses with congenital abnormalities. Data are from a single center (Policlinico di Modena); all fetuses included were born between 2017 and 2018 and with a follow-up of at least 6 months. We included all deliveries (including perinatal deaths) and termination of pregnancy (TOP) for fetal indication. We calculated sensibility, sensitivity, Positive and Negative Likelihood Ratio, positive and negative predictive value of ultrasound. RESULTS: During the study period 5920 deliveries, including perinatal deaths, and 28 TOP for fetal indication were registered at our center. The prevalence of congenital malformations was 2.6% (153/5920). At least one ultrasound was performed in our center in 1250 women delivering in our unit. All 28 TOP had the anomaly scan performed in our center. Among the total 1278 women scanned in our unit, there were 128 (10%) suspicious scans. In 5/128 (3.9%) cases we diagnosed a false alarm; in 8/128 (6.2%) cases an evolutive malformation with in-utero regression. The prenatal diagnosis was confirmed in 77 (60.2%) cases at birth and in 28/128 (21.9%) at postmortem analysis while there were 10/128 false positive (7.8%). Among the 153 congenital malformations diagnosed at birth, the anomaly scan was performed in our Prenatal Medicine Unit in 92 (60.1%) fetuses. Among these, there were 15 false negatives (9.8%) while in 77/92 (83.7%) the malformation at birth agreed with the sonographic diagnosis. Sensitivity and specificity of ultrasound were 87.5% (IC95 80.2-92.8%) and 99.1% (IC95 98.4-99.6%) respectively with a Positive Likelihood Ratio and Negative Likelihood Ratio of 101.3 (IC95 54.5-188.5) and 0.13 (IC95 0.08-0.2); Positive Predictive Value and Negative Predictive Value were 91.3% (IC95 85-95.1%) and 98.7(IC95 98-99.2%). CONCLUSION: Anomaly scan in pregnancy allows the diagnosis of congenital malformations with a sensibility of 87.5% and specificity of 99.1%. The main limitations of this study are its retrospective design and that it was conducted in a single referral center.

Maternal and neonatal outcomes of pregnancies complicated by late fetal growth restriction undergoing induction of labor with dinoprostone compared with cervical balloon: A retrospective, international study.

INTRODUCTION: The aim of this study was to compare vaginal dinoprostone and mechanical methods for induction of labor (IOL) in pregnancies complicated by late fetal growth restriction. MATERIAL AND METHODS: Multicenter, retrospective, cohort study involving six referral centers in Italy and Spain. Inclusion criteria were pregnancies complicated by late fetal growth restriction as defined by Delphi consensus criteria. The primary outcome was the occurrence of uterine tachysystole; secondary outcomes were either cesarean delivery or operative vaginal delivery for non-reassuring fetal status, a composite score of adverse neonatal outcome and admission to neonatal intensive care unit (NICU). Univariate and multivariate logistic regression analysis was used to analyze the data. RESULTS: A total of 571 pregnancies complicated by late fetal growth restriction undergoing IOL (391 with dinoprostone and 180 with mechanical methods) were included in the analysis. The incidence of uterine tachysystole (19.2% vs. 5.6%; p = 0.001) was higher in women undergoing IOL with dinoprostone than in those undergoing IOL with mechanical methods. Similarly, the incidence of cesarean delivery or operative delivery for non-reassuring fetal status (25.6% vs. 17.2%; p = 0.027), composite adverse neonatal outcome (26.1% vs. 16.7%; p = 0.013) and NICU admission (16.9% vs. 5.6%; p < 0.001) was higher in women undergoing IOL with dinoprostone than in those undergoing IOL with mechanical methods. At logistic regression analysis, IOL with mechanical methods was associated with a significantly lower risk of uterine tachysystole (odds ratio 0.26, 95% confidence interval 0.13-0.54; p < 0.001). CONCLUSIONS: In pregnancies complicated by late fetal growth restriction, IOL with mechanical methods is associated with a lower risk of uterine tachysystole, cesarean delivery or operative delivery for non-reassuring fetal status, and adverse neonatal outcome compared with pharmacological methods.

Pregnant woman infected by Coronavirus disease (COVID-19) and calcifications of the fetal bowel and gallbladder.

COVID-19 was declared to be a pandemic due to the rapid increase of cases around the world, including the number of pregnant women. Data about vertical transmission of COVID-19 are still limited and controversial: in most cases, although a positive mother, the virus could not be isolated in amniotic fluid, cord blood, breast milk or neonatal throat swab in these patients. No data have been published about possible intrauterine sonographic signs of infection. A pregnant woman was diagnosed with SARS-CoV-2 at 35+5 weeks of gestation and managed conservatively at home. At transabdominal ultrasound at 38+3 weeks, fetal bowel and gallbladder calcifications were noted. CMV and other infectious agents were ruled out; an iterative caesarean section was performed at 38+5 weeks without complications. Placenta resulted negative for SARS-CoV-2; the umbilical cord blood sample was IgG positive and IgM negative as per maternal infection. The baby developed respiratory distress syndrome requiring endotracheal surfactant administration and nasal-CPAP for one day but nasopharyngeal swabs at birth and after 48 hours were SARS-CoV-2 negative. Neonatal abdominal ultrasound showed normal liver, acalculous gallbladder with mild parietal thickening. The baby was discharged in good conditions. Although gallbladder calcifications and echogenic bowel are highly suspicious of viral infection and were thought to be due to the vertical transmission of SARS-CoV-2, these findings were not corroborated by the results of our diagnostic tests; these sonographic findings might represent a false positive of fetal infection in mother affected by COVID-19 since vertical transmission appears to be rare.

Perinatal outcomes of twin pregnancies affected by early twin-twin transfusion syndrome: A systematic review and meta-analysis.

INTRODUCTION: Twin-to-twin transfusion syndrome (TTTS) is associated with a high risk of perinatal mortality and morbidity if not treated. However, the optimal timing and management in case of early (occurring < 18 weeks) TTTS has not been established yet. MATERIAL AND METHODS: This is a systematic review and meta-analysis aiming at evaluating the outcomes of monochorionic diamniotic twin pregnancies complicated by early (ie before 18 weeks) TTTS according to different management options (expectant, laser therapy, amnioreduction or cord occlusion). The primary outcome was mortality, including single and double intrauterine, neonatal and perinatal death. Secondary outcomes were: composite morbidity, neuromorbidity, respiratory distress syndrome, admission to neonatal intensive care unit, intact survival (defined as survival free from neurological complications) and preterm birth < 32 weeks of gestation. All outcomes were reviewed according to the different management options (expectant, laser therapy, amnioreduction or cord occlusion) and reported FOR the overall population of twins, and for the donor and recipient separately. Subgroup analysis for TTTS occurring before 16 weeks of gestation was performed. Random-effect meta-analyses of proportions were used to analyse the data. RESULTS: Thirteen studies were included. Early TTTS occurred in 14.3% (95% confidence interval [CI] 11.9-17.0) of cases. The incidence of intrauterine death was 19.0% (95% CI 2.6-45.5) in twins managed expectantly, 32.4% (95% CI 16.5-50.7) in those who received laser treatment and 12.5% (95% CI 4.8-23.0) in those treated with amnioreduction. The incidence of neonatal death was 22.6% (95% CI 4.2-49.8) in twins managed expectantly, 24.7% (95% CI 0.5-80.3) in those who received laser and 20.2 (95% CI 5.8-43.4) in those who had amnioreduction; it was not possible to compute the incidence of these outcomes in twins undergoing cord occlusion because of insufficient sample and lack of reporting of most of the observed outcomes. Overall, the incidence of perinatal death was 43.9% (95% CI 5.9-87.7) in twins managed expectantly, 47.3% (95% CI 21.4-70.0) in those treated with laser and 28.5% in those who had amnioreduction. CONCLUSIONS: Twin pregnancies affected by early TTTS are at substantial risk of perinatal mortality and morbidity; however, the data come from very small studies with a high risk of selection bias.
