Accurate antenatal diagnosis of placenta accreta spectrum (PAS) is important for optimal management. The purpose of this study was to compare the respective capabilities of 1.5-T and 3.0-T MRI in the diagnosis of PAS.Between March 2016-March 2021, 190 pregnant women at high risk for PAS underwent dedicated prenatal MRI with either 1.5-T or 3.0-T units at a tertiary imaging center. Cesarian section and MRI were performed less than 6 weeks from each other. Prospectively collected data were evaluated by two experienced genitourinary radiologists for presence and extent of PAS. A comparative study was designed to investigate differences in predictive ability between 1.5-T and 3.0-T MRI groups. Sensitivity, specificity, accuracy, negative and positive prognostic values relative to intraoperative/histological findings, were computed for both groups and were compared with chi-square (χ 2) test. Interobserver agreement was estimated using Kappa test.One hundred-eighty-two gravid women were included in the study; of these, 91/182 (50%) women were evaluated with 1.5-T (mean age, 35 ± 5.1 [SD] years; mean gestational age: 32.5 weeks) and 91/182 (50%) with 3.0-T MRI (mean age, 34.9 ± 4.9 [SD] years; mean gestational age, 32.1 weeks). 1.5-T MRI yielded 95.7% sensitivity (95% CI: 87.8-99.1) and 81.8% specificity (95% CI: 59.8) and 3.0-T MRI 93.8% sensitivity (95% CI: 86.0-97.9) and 83.3% specificity (95% CI: 48.2-97.7) for PAS identification, with no differences between the two groups (P = 0.725 and P0.999, respectively). MRI showed excellent predictive ability for detecting extrauterine placental spread with 100% sensitivity (95% CI: 89.4-100.0), 96.7% specificity (95% CI: 88.1-99.6) for 1.5-T and 97% sensitivity (95% CI: 84.2-99.9), 96.7% specificity (95% CI: 88.1-99.6) for 3.0-T without differences between the two groups (P0.999). Interobserver agreement was excellent for both groups. The most frequently detected MRI signs of PAS for both 1.5-T and 3.0-T groups were placental heterogeneity (n = 85, 93.5% vs. n = 90, 98.9%; P = 0.413), and intraplacental fetal vessels (n = 64, 70.3% vs. n = 65, 71.4%; P = 0.870).This study suggests that 3.0-T MRI and 1.5-T MRI are equivalent for the diagnosis of PAS.

The primary aim of this review is to estimate the prevalence of ARSA both in euploid fetuses as well as in fetuses with Down Syndrome. Secondary objectives were to estimate the association of ARSA with cardiac anomalies and chromosomal defects, especially trisomy 21 and 22q11 deletion (DiGeorge Syndrome). The incidence of ARSA in normal population varies from 0.35% to 3.5%, based on different studies. Since the first reported association between ARSA and trisomy 21 in 2015 until today, several studies have emerged to confirm different degrees of this correlation. Indeed, ARSA appears to be a clinically useful prenatal ultrasound marker for trisomy 21. Particularly, most recent studies concluded that ARSA as a non-isolated finding can be used as screening for Down syndrome. However, when ARSA is an isolated finding, various studies proved that there is no significant correlation with Down syndrome. Apart from these, ARSA appears to be associated with other chromosomal abnormalities, such as 22q11 deletion, cardiac defects and other morphological anomalies. As a conclusion ARSA should be characterized as isolated or non-isolated, as the non - isolated ARSA appears to be a clinically useful marker of Down syndrome and thus, additional testing is required when diagnosed.

Influenza is associated with an increased risk for serious illness, hospitalization, and death in pregnant women and young infants. Our aim was to estimate the effectiveness of a quadrivalent inactivated influenza vaccine (QIV) in pregnant women and their infants during 2019-2020.A QIV vaccine was offered to pregnant women followed in a maternity hospital. Women were contacted weekly during the influenza season and asked about symptoms. Polymerase chain reaction testing in pharyngeal samples was offered to pregnant women and infants with influenza-like illness. A Bayesian beta-binomial model was used.We studied 636 pregnant women (406 vaccinated and 230 unvaccinated) and 474 infants (281 of mothers vaccinated in pregnancy and 193 of unvaccinated mothers). Using a Bayesian beta-binomial model, it was estimated that influenza vaccination of pregnant women reduced their logit to develop laboratory-confirmed influenza by -4.2 (95% CI -3,7 - 4,7) and the logit of their infants to develop laboratory-confirmed influenza by -4.2 (95% CI -3.6, -4.9). The QIV effectiveness against laboratory-confirmed influenza was 43.5% in pregnant women and 31.4% in infants.Maternal influenza vaccination with QIV in pregnancy reduced the odds of pregnant women and their infants to develop influenza.www.clinicaltrials.gov identifier is NCT04723771.

Objectives We designed an electronic query that was distributed to healthcare workers in order to evaluate their attitudes towards COVID-19 vaccination of women that wish to conceive and those that are pregnant. Methods An electronic survey was designed and distributed through a network of 5.654 e-mails. The query was uploaded in Google Forms. Results Overall, 1,226 answers were retrieved. Ninety percent of respondents replied that they prescribe COVID-19 vaccination in women that wish to conceive, however, the rate falls to 80% for those that have schedules for imminent artificial reproductive techniques. Approximately 1 in 2 physicians (obstetricians and pediatricians) suggests that a delay in assisted reproduction following immunization is not recommended. At least 13% of women of reproductive age and 30% of women wishing to conceive with ART declined to do so according to respondents, report. Only 75% of respondents favored immunization during pregnancy and of those 48% responded that vaccination could be done in all trimesters of pregnancy. Approximately 40% of women decline; however, to receive vaccination. Conclusions Despite the directions provided by international organizations; physician and patient hesitancy towards vaccination during pregnancy (and particularly the first trimester) remains an issue that deserves further attention.

The aim of this study is to investigate the predictive value of low levels of pregnancy associated plasma protein-A (PAPP-A) during the first trimester on adverse pregnancy outcomes, namely pregnancy induced hypertension (PIH), preeclampsia (PE), intrauterine growth restriction (IUGR), and fetal loss.This is a prospective cohort study including 2636 women with singleton pregnancies that attended the Prenatal Diagnosis Unit of the First Department of Obstetrics and Gynecology of National and Kapodistrian University of Athens in "Alexandra Hospital" between 2017 and 2019 for the first trimester combined screening routine scan. The study population was divided into two groups according to their PAPP-A levels. The cut-off value of the PAPP-A level was defined as the 0.4 multiple of median (MoM) which is in correspondence with the fifth centile. The women were followed-up prospectively until delivery and the primary outcome measures were the incidence of PIH, PE, IUGR (10th centile), and fetal loss. Results: PAPP-A levels of ≤0.4 MoM were associated with increased maternal body mass index (BMI), increased uterine arteries pulsatility index (PI), and lower birth weight. Women with PAPP-A levels ≤0.4 MoM were more likely to develop PE (2.3% vs. 0.2%, p0.001), PE or PIH (2.3% vs. 0.4%, p=0.003), IUGR (2.3% vs. 0.4%, p=0.003), and combined adverse outcome (25.5% vs. 1.9%, p0.001) compared to women with PAPP-A0.4 MoM.This study confirms that among women with PAPP-A levels ≤0.4 MoM in the first trimester, there are increased odds for PE or PIH, IUGR, and combined composite pregnancy outcome.

Evidence indicates that SARS-CoV-2 infection increases the likelihood of adverse pregnancy outcomes. Modifications in the circulatory, pulmonary, hormonal, and immunological pathways induced by pregnancy render pregnant women as a high-risk group. A growing body of research shows that SARS-CoV-2 infection during pregnancy is connected to a number of maternal complications, including pneumonia and intensive care unit (ICU) hospitalization. Miscarriages, stillbirth, preterm labor, as well as pre-eclampsia and intrauterine growth restriction are also among the most often documented fetal implications, particularly among expecting women who have significant COVID-19 symptoms, often affecting the timing and route of delivery. Thus, prevention of infection and pharmacological treatment options should aim to minimize the aforementioned risks and ameliorate maternal, obstetric and fetal/neonatal outcomes.

In the present study we sought to compare the efficacy of cervical pessary to that of cerclage in terms of reducing preterm birth rates among women with a short (25 mm) and ultra-short (15 and10 mm) cervix during the ultrasonographic second trimester assessment.We retrospectively searched the hospital records for singleton pregnancies diagnosed with cervical insufficiency during the second trimester of pregnancy. The McDonald cerclage was used in all women with the use of a 5mm Mersilene tape. Arabin pessary was used uniformly. In all cases 80 mg of vaginal progesterone gel was administered daily, until 37 weeks of gestation.Overall, 294 women were selected for analysis of whom 124 (42.2%) had a McDonald cerclage and 170 (57.8%) had placement of an Arabin pessary. Preterm birth rates37 weeks were similar in both groups (C: 30/122 vs P: 35:165, p=.581) as well as PTB34 weeks (C: 16/122 vs 15/150, p=.278). Admission to the NICU and need for CPAP were more prevalent in the cerclage group (p.001). Analysis of cases with a cervix15 mm and10 mm indicated that preterm birth rates remained equal among groups whereas an increased risk of NICU admission in cases with cervical length10 mm that were treated with cerclage.Cervical pessary may be an alternative to cervical cerclage for women with second trimester cervical shortening and its effect may persist even among cases with an ultra-short cervix. Future randomized trials are needed to ascertain these findings.

Venous thrombotic events (VTE) prevalence is estimated to be 1-2 for every 10,000 pregnancies, making it one of main causes of maternal mortality in developed countries. VTE’s leading risk factors are history of the condition and hereditary thrombophilia. D-dimer tests conducted during pregnancies have in many cases led to false positive results while a few false negatives have also been found. For pregnant women, it is important for evaluation to begin with compression ultrasound before magnetic resonance imaging, which seeks a negative test and focuses on the pelvis. On the other hand, a chest x-ray should be done for pulmonary embolism, which helps in deciding between a CT pulmonary angiogram and perfusion study for normal and abnormal x-ray, respectively. Generally, treatment is composed of heparin of low molecular weight for at least six weeks after childbirth. Thrombolysis can be significant for life-threatening and serious thrombolysis. For populations at high risk, VTE prophylaxis still faces a lot of uncertainty. In fact, there is still little evidence to support the essence of mechanical prophylaxis for all women who have delivered through cesarean.

Myomectomy in pregnancy, until this day, remains very controversial. We present two cases of successful antepartum myomectomies performed in the second trimester of gestation. In both cases, the initial suspected origin of these tumours was the ovaries. However, as it was shortly after confirmed, since both women underwent laparotomy, the diagnosis of these masses was uterine fibroids. Both cases resulted on the live birth of two healthy infants via caesarean section. Secondarily, we conducted a thorough review of current data of myomectomies performed during pregnancy, including the characteristics and diagnosis of the myomas of pregnant women, the surgical details and complications, along with the outcomes of these gestations. Overall, the analysis of cases published in international literature, suggests that the surgical removal of myomas during pregnancy can be considered safe, given certain indications and considerations. Our review comprises of 71 women undergoing excision of fibroids during pregnancy. Only three cases ended in a miscarriage while the remaining 68 resulted in a second or third trimester delivery. However, the data concerning the safety of the procedure are scarce and originate mostly from case reports. Thus, conclusions on the exact maternal and obstetrical complication rates cannot be drawn.

Vaccine hesitancy has been recognized by the World Health Organization as one of ten threats to public health globally in 2019. Pregnant women constitute an extremely important group for the study of knowledge and attitudes towards pediatric vaccinations. This is a cross-sectional survey conducted in two maternity hospitals in Athens. A standardized questionnaire was used. A total of 814 pregnant women with a mean age of 33.1 years and a mean gestational age of 24.4 weeks were studied. Overall, 717 (89%) of 804 pregnant women reported that they intend to vaccinate their baby in accordance with the National Vaccination Program, 7 (1%) that they do not, while 80 (10%) reported that they have not decided yet. The women provided a mean of 11.4 correct replies out of 14 questions about vaccine-preventable diseases and vaccines (mean knowledge score: 81.5%). A pediatrician has been recognized as the source for information about vaccines in most cases (611/809, 75.5%), while in 215 (26.6%) the internet was also used. Overall, pregnant women trusted physicians about information for vaccines ("very much trusted" in 55.9% and "quite trusted" in 40% of cases). Lastly, 642 (81%) women agreed with the statement "vaccinations should be mandatory for school entry" while 70 (9%) women agreed with the statement "parents should have the right to refuse their children vaccinations". A multivariate analysis found that a gestational age of ≤20 weeks (OR = 2.33, CIs: 1.27-4.28, p-value = 0.006), having another child (OR = 4.44, CIs: 2.30-8.58, p-value < 0.001), a history of influenza vaccination (OR = 2.54, CIs = 1.37-4.71, p-value = 0.003), and a higher knowledge score about vaccine-preventable diseases and vaccines (OR = 1.33, CIs: 1.23-1.45, p-value < 0.001) were significantly associated with an increased probability to get their child vaccinated in accordance with the National Vaccination Program.

Background. Gynecologic melanomas are extremely rare malignancies, and primary malignant melanoma of the cervix (PMMC) is the rarest among them all, with less than 100 cases reported so far. Although some conditions have been correlated with the pathogenesis of this entity, no specific risk factor has been yet identified, with vaginal bleeding being the most common symptoms. The diagnosis is based on physical examination with speculum assessment and cytologic and histopathologic findings accompanied with immunohistochemical staining of lesion’s biopsies. Case Presentation. We report a case of PMMC in a 34-year-old para-2 patient, among the youngest cases of PMMC reported, that presented to our clinic for routine examination. Gynecologic examination demonstrated a dark, heavily fully pigmented cervical growth completely covering the entire external cervical os. Biopsy obtained and showed malignant melanoma. She underwent radical hysterectomy with bilateral salpingo-oophorectomy and pelvic lymphadenectomy. The pathological diagnosis was FIGO stage IB1 PMMC. Despite 2 courses of anti-PD-1 antibody (Nivolumab) treatment, the patient passed away 13 months after diagnosis (12 months after surgery). Conclusions. Early diagnosis and subsequently early treatment are of high importance regarding patients’ prognosis and survival. No standardized protocols or treatment guidelines specific for this rare cancer have been issued; thus, clinicians are called to assess each case individually. Current treatment options are based on surgical excision mostly with radical hysterectomy, but in advanced or recurrent state of the disease, other treatment modalities, such as chemotherapy, radiotherapy, and immunotherapy, can be employed. Prognosis for these patients is very poor, and survival rate remains extremely low, with the median OS reported being less than 2 years. Reporting and publishing of such cases are both of paramount importance for the better understanding of this uncommon cervical malignancy, and further biological and clinical investigations are required for more suitable and effective therapies to be determined. A new staging system, specific to PMMC, could be of great use for the better correlation of the disease’s stage and prognosis of these patients.

Background. The coexistence of an intrauterine pregnancy and an ectopic pregnancy (heterotopic pregnancy) is an extremely rare, yet major, complication during pregnancy. The early diagnosis of a heterotopic pregnancy is of great importance for fetal viability, maternal safety, and the progression of an uncomplicated intrauterine pregnancy. Case Presentation. We report a case of a naturally conceived heterotopic tubal pregnancy in a 37-year-old primigravida. The patient presented with continuous, dull, lower abdominal pain and a positive urine pregnancy test which was conducted a week prior to the start of the pain. The patient was hospitalized, and based on the clinical image and after strict monitoring, she was diagnosed with a heterotopic pregnancy. She was treated with laparoscopic salpingectomy after the rupture of the ectopic pregnancy while the desired intrauterine gestation continued without any complications. The pregnancy resulted in the birth of a healthy infant through vaginal delivery. Discussion. Strict monitoring with multiple sonographic evaluations should always be conducted in women with abnormal serum beta-hCG, adnexal abnormalities, or clinical symptoms, while heterotopic pregnancy should be in differential diagnosis and treatment should not be delayed since emerge management is important for the progression of the intrauterine pregnancy.

Introduction: It is well known that music acts as an analgesic. Facilitates muscle relaxation, reduction of physical pain and mental tension. Purpose of this original investigation: study the effect of music on maternal anxiety during cardiotocography as well as its effect on embryonic cardiac function in relation to mother’s heart rate. Method and materials: The survey, conducted in external midwifery medical services of Alexandra’s Hospital, involved 80 pregnant women who met the criteria for participation. They were divided in two groups. The 40 pregnant women were the Musical Group, and the other 40 were the Control Group. In both groups, the STAI scale was used. The control group underwent cardiotocography examination without listening to music. The Musical Group were selected to hear the music track ‘Kung Fu Piano: Cello Ascends’, a cover of the Piano Guys band. The hearing started 5 minutes before the end of the cardiotocography, with headset playing frequencies that are within the frequency spectrum of the music track and special music player, and 10 minutes before the end of the cardiotocography the pulse oximeter Beurer P080 was placed. In this music track we did music and frequency analysis with the following programs: SPAN of Voxeno and Reaper of Cocos, as well as Theory-Harmony of Music, to see if at the time certain changes in the track occur, there are corresponding changes in the heart rate of the mother and the fetus. Results: In our study we observed that music significantly decreased the level of anxiety of women subjected to non-stress test (NST) (Median anxiety score prior to the conduct of the non-stress test 53.38 (49-57) vs 25.20 (23-28) following the completion of the test. Moreover differences among women that heard music were significant compared to those that did not (25.20 (21-28) vs 56 (48-64)) despite the fact that baseline differences among the two groups were comparable (54.45 (59-67) vs 50.80 (53-58). Finally, following performance of music analysis we observed significant variations in the baseline heartbeat of pregnant women as well as in the cardiotocographic analysis of fetuses (number of accelerations, baseline rhythm); those patterns were directly related to musical characteristics of the track that women listened to. Conclusions: Music has a positive effect on pregnancy. It is a non-invasive way of anxiety relief, as well as a simple, non-time-consuming way of improving cardiotocography among low risk cases; thus, potentially diminishing false-positive results which may result in unnecessary deliveries.

BackgroundThe aim of the current study is the longitudinal epidemiological study of pregnancies, their outcome and the changes in their treatment, in patients with hemoglobinopathies, during 30 years at a Thalassemia and Sickle Cell Department.MethodsThe data of a total of 47 pregnancies of 40 women with hemoglobinopathies monitored in the Thalassemia and Sickle Cell Department of Hippokrateio General Hospital of Athens were retrospectively collected. The data were divided and evaluated in two time periods, the first before 2000 and the second between 2000 and 2017.ResultsThere were four miscarriages and 43 completed pregnancies. The mean pregnancy duration was 34.92 weeks. Thalassemia major and thalassemia intermedia patients had higher percentages of in vitro fertilization (IVF) pregnancies and IVF attempts, with the majority of IVF attempts and pregnancies in the time period after 2000. During the period 2000–2017, more women received transfusions and iron chelation therapy both before and during pregnancy compared to the period before 2000. During the period 2000–2017, three women presented hemorrhagic complications. Placental abruption occurred in two cases, while one woman suffered a stroke. Six women had liver disease and two cardiac problems.ConclusionThe rate of pregnancies in women with hemoglobinopathies has increased after the year 2000 due to the increased use of IVF technique. Pregnancy planning, close collaboration between gynecologists and hematologists and appropriate pregnancy monitoring are essential for an optimal pregnancy outcome.

Influenza is associated with an increased risk for serious illness, hospitalization and/or death in pregnant women and young infants. We prospectively studied the effectiveness of a quadrivalent inactivated influenza vaccine (QIV) in pregnant women and their infants during the 2018-2019 influenza season. A QIV was offered to pregnant women cared in a maternity hospital in Athens. Women were contacted weekly by telephone during the influenza season and PCR test was offered to women or infants who developed influenza-like illness (ILI). We studied 423 pregnant women and 446 infants. Unvaccinated pregnant women had a 7.5% probability to develop laboratory-confirmed influenza compared to 2.1% among vaccinated women (Odds ratio: 3.6; confidence intervals: 1.14-11.34, p-value = 0.029). Infants whose mothers were not vaccinated had a 7.9% probability to develop laboratory-confirmed influenza compared to 2.8% among infants of vaccinated mothers (Odds ratio = 2.849, confidence intervals: 0.892-9.102, p-value = 0.053). Cox regression analyses showed that QIV vaccination was significantly associated with a decreased probability for laboratory-confirmed influenza, ILI, healthcare seeking and hospitalization among pregnant women and a decreased probability for laboratory-confirmed influenza, healthcare seeking and prescription of antibiotics among infants. The effectiveness of QIV against laboratory-confirmed influenza was 72% among pregnant women and 64.5% among infants during the 2018-2019 influenza season. Vaccination of pregnant women with the QIV was associated with a lower risk for laboratory-confirmed influenza for them and their infants during the influenza season. Our findings strongly support the World Health Organization recommendations for vaccinating pregnant women against influenza.

Aim:: To provide a review considering microRNAs regulating oncogenes and tumor suppressor genes during the different stages of cell cycle, controlling carcinogenesis. Methods:: The role of microRNAs involved as oncogenes’ and tumor suppressor genes’ regulators in cancer was searched in the relevant available literature in MEDLINE, including terms such as “microRNA”, “oncogenes”, “tumor suppressor genes”, “metastasis”, “cancer” and others. Results:: MicroRNAs determine the expression levels of multiple cell cycle regulators, such as cyclins, cyclin dependent kinases and other major cell cycle activators including retinoblastoma 1 (RB- 1) and p53, resulting in alteration and promotion/inhibition of the cell cycle. Conclusion:: MicroRNAs are proven to have a key role in cancer pathophysiology by altering the expression profile of different regulator proteins during cell division cycle and DNA replication. Thus, by acting as oncogenes and tumor suppressor genes, they can either promote or inhibit cancer development and formation, revealing their innovative role as biomarkers and therapeutic tools.

Aim: The study aimed to provide an overall view of current data considering the presence of microRNAs in amniotic fluid. Methods: The available literature in MEDLINE, regarding the role of the amniotic fluid in pregnancy and fetal development, was searched for related articles including terms such as “microRNA”, “Amniotic fluid”, “Adverse outcome” and others. Results: The amniotic fluid has an undoubtedly significant part in fetal nutrition, with a protecting and thermoregulatory role alongside. MicroRNAs have proven to be highly expressed during pregnancy in many body liquids including amniotic fluid and are transferred between cells loaded in exosomes, while they are also implicated in many processes during fetal development and could be potential biomarkers for early prediction of adverse outcomes. Conclusion: Current knowledge reveals that amniotic fluid microRNAs participate in many developmental and physiological processes of pregnancy including proliferation of fibroblasts, fetal development, angiogenesis, cardioprotection, activation of signaling pathways, differentiation and cell motility, while the expression profile of specific microRNAs has a potential prognostic role in the prediction of Down syndrome, congenital hydronephrosis and kidney fibrosis.

Labour has high importance for every woman’s life but also is the moment when many complications might appear increasing significantly morbidity and mortality. Therefore obstetricians have to help women in labour to give birth to their babies naturally, with the highest satisfaction possible. Western standards suggest that women should experience their partirution in the lithotomy or the supine position. However, upright positions have the potential to reduce second stage of labour and to improve neonatal outcomes. Intrapartum ultrasound using different parameters can predict the remaining time to delivery and therefore to make timely interventions in order to decrease instrumental or caesarean deliveries and postpartum hemorrhage as these are the most important complications met in prolonged second stage of labour. In this review the optimal positioning of the women in labour will be presented. Additionally, the ability of intrapartum to shorting second stage duration and to increase maternal satisfaction concerning childbirth will also mentioned.

BACKGROUND Placenta accreta spectrum (PAS) disorders may be associated with significant mortality and morbidity for both mother and fetus. PURPOSE/HYPOTHESIS To identify MRI risk factors for poor peripartum outcome in gravid patients at risk for PAS. STUDY TYPE Prospective. POPULATION One hundred gravid women (mean age: 34.9 years) at third trimester, with placenta previa. FIELD STRENGTH/SEQUENCE T2 -SSTSE (single-shot turbo spin echo), T2 -TSE, T1 -TSEFS (TSE images with fat-suppression) at 1.5T. ASSESSMENT Fifteen MRI features considered indicative of PAS were recorded by three radiologists and were tested for any association with the following adverse peripartum maternal and neonatal events: increased operation time, profound blood loss, hysterectomy, bladder repair, ICU admission, prematurity, low birthweight, and 5-minute APGAR score 0.75, P < 0.001) between MRI and intraoperative findings for invasive placenta, bladder and parametrial involvement. Intraplacental T2 dark bands, myometrial disruption, uterine bulge, and hypervascularity at the utero-placental interface or parametrium, showed significant association (P < 0.005) with poor clinical outcome for both mother and fetus. The MRI score showed significant predictive ability for each adverse maternal event (area under the curve [AUC]: 0.85-0.97, P < 0.001). The presence of ≥3 MRI signs was the cutoff point for a complicated delivery (OR: 19.08, 95% confidence interval [CI]: 6.05-60.13) and ≥6 MRI signs was the cutoff point for massive bleeding (OR: 90.93, 95% CI: 11.3-729.23), hysterectomy (OR: 72.5, 95% CI: 17.9-293.7), or extensive bladder repair (OR: 58.74, 95% CI: 7.35-469.32). The MRI score was not significant for predicting adverse neonatal events including preterm delivery (P = 0.558), low birthweight (P = 0.097), and 5-minute Apgar score (P = 0.078). DATA CONCLUSION Preoperative identification of specific MRI features may predict peripartum course in high-risk patients for PAS. LEVEL OF EVIDENCE 1 Technical Efficacy: Stage 5 J. Magn. Reson. Imaging 2019;50:602-618.

Background Turner syndrome is a chromosomal abnormality, due to a total or partial loss of 1 of the X chromosomes and is mostly characterized clinically by short stature and primary ovarian insufficiency. Spontaneous pregnancies are rare (5%) and of relatively high risk. This is 1 of few reported cases of spontaneous conception and favorable prognosis in a patient with Turner syndrome and a 45,X/47,XXX karyotype. Case A 21-year-old woman with Turner mosaicism (45,X/47,XXX) who had a full-term, uncomplicated pregnancy after spontaneous conception, gave birth to a healthy female (46,XX) infant. Summary and Conclusion Spontaneous pregnancies in women with Turner syndrome are a rarity. Fertility preservation methods are being discussed. Due to the high reported incidence of neonatal, obstetric, maternal, and especially cardiovascular complications in those pregnancies, close monitoring is essential.

Objectives The aim of our study is to present the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in pregnancy and evaluate its impact on maternal and neonatal outcomes. Methods We retrospectively reviewed the medical records of all COVID-19 positive pregnant women who were admitted to “Alexandra” maternity hospital from March to December 2020 (n=40). The infection status was determined via real-time polymerase chain reaction (RT-PCR) of nasopharyngeal swab specimen. We documented the demographic features, clinical status, pregnancy characteristics and maternal and fetal outcomes. Results Forty COVID-19 positive pregnant women were admitted to our clinic during the study period. Mean maternal age was 27.6 years. Gestational age (GA) ranged from 10–42 weeks of pregnancy with mean GA calculated at 38+3 weeks. Associated comorbidities included hypertension, hypothyroidism, epilepsy, hepatitis B and asthma. Thirty-five out of 40 women delivered within the study period. Cesarean section was performed in 57.1% of the cases. Most of the cases (87.5%) were asymptomatic while ventilation was required for only one patient. All neonates tested negative for SARS-CoV-2. Neither maternal nor neonatal deaths occurred. Conclusions In alignment to other studies, our data show that the course of coronavirus disease 2019 (COVID-19) during pregnancy in the majority of cases is mild and neonatal outcomes also appear favorable.

Fallopian tube cancer is an extremely rare gynecological condition, accounting for just 1 to 2% of all female tract malignancies. The mean age of diagnosis is similar to that of ovarian cancer, between 60 and 75 years, but it can affect a wide spectrum of ages. Advanced age and family history of ovarian and breast cancer are the main risk factors, since they are associated with increased incidence of this uncommon entity. In this study, we report a rare case of an elderly, 89-year-old patient that presented to our clinic due to vaginal bleeding.

The Notch signaling pathway regulates the development of embryonic and tissue homeostasis of various types of cells. It also controls cell proliferation, variation, fate and cell death because it emits short-range messages to nearby cells. The pathway plays an important role in the pathophysiology of various malignancies, controlling cancer creation. It also limits cancer development by adjusting preserved angiogenesis and cellular programs. One of the Notch signaling ligands (in mammals) is Delta-like ligand 4 (Dll4), which plays a significant role in the overall malignancies’ advancement. Particularly, sequencing Notch gene mutations, including those of Dll4, have been detected in many types of cancers portraying information on the growth of particular gynecological types of tumors. The current research article examines the background theory that implies the ability of Dll4 in the development of endometrial and other cancer types, and the probable therapeutic results of Dll4 inhibition.

Background Prenatal identification of placenta accreta spectrum (PAS) disorder is essential for treatment planning. More objective means for predicting PAS and clinical outcome may be provided by MRI descriptors. Purpose To investigate the association of intraplacental fetal vessel (IFV) diameter at MRI with PAS and peripartum complications. Materials and Methods Between March 2016 and October 2019, 160 gravid women suspected of having PAS underwent placental MRI as part of a prospective trial. Secondary analysis was performed by two experienced genitourinary radiologists for presence and maximum diameter of IFVs. Relative risk ratios were computed to test the association of IFVs with presence and depth of PAS invasiveness. Receiver operating characteristic analysis was used to evaluate the ability of IFV diameter to help predict PAS, placenta percreta, and peripartum complications and for comparison of the area under the curve (AUC) versus that from other combined MRI predictors of PAS (eg, myometrial thinning, intraplacental T2-hypointense bands, uterine bulge, serosal hypervascularity, and signs of extrauterine placental spread). Intraoperative and histopathologic findings were the reference standard. Results A total of 155 women were evaluated (mean age, 35 years ± 5 [standard deviation]; mean gestational age, 32 weeks ± 3). PAS was diagnosed in 126 of 155 women (81%) (placental percreta in 68 of 126 [54%]). At delivery, 30 of 126 women (24%) experienced massive blood loss (>2000 mL). IFVs were detected at MRI in 109 of 126 women with PAS (86%) and in 67 of 68 women with placental percreta (98%). The relative risk ratio was 2.4 (95% CI: 1.6, 3.4; P < .001) for PAS and 10 (95% CI: 1.5, 70.4; P < .001) for placental percreta when IFVs were visible. IFVs of 2 mm or greater were associated with PAS (AUC, 0.81; 95% CI: 0.67, 0.95; P = .04). IVFs of 3 mm or greater were associated with placenta percreta (AUC, 0.81; 95% CI: 0.73, 0.89; P < .001) and with peripartum complications, including massive bleeding (AUC, 0.80; 95% CI: 0.71, 0.89; P < .001). Combining assessment of IFVs with other MRI descriptors improved the ability of MRI to predict PAS (AUC, 0.94 vs 0.89; P = .009). Conclusion Assessment of intraplacental fetal vessels with other MRI descriptors improved the ability of MRI to help predict PAS. Vessel diameter of 3 mm or greater was predictive of placenta percreta and peripartum complications. © RSNA, 2020 Online supplemental material is available for this article.
