RESUMEN
RESEARCH QUESTION: How do clinical rectovaginal examination and transvaginal ultrasound examination perform in the diagnosis of parametrial infiltration in patients with endometriosis? DESIGN: This was a multicentre prospective observational study. Patients with suspected deep endometriosis at clinical examination and/or at ultrasound evaluation and scheduled for surgery were included. Following multicentre multidisciplinary meetings, consensus was obtained on terms and methodology to define the parametrium at pelvic anatomy, ultrasound and surgery. Sensitivity, specificity, accuracy, and positive and negative likelihood ratios were calculated for clinical and ultrasound examinations with respect to surgery. RESULTS: In total, 195 women were selected for the present study and 164 were included in the analysis. Ultrasound examination had good to high specificity (>80%) for all parameters, except the left lateral parametrium (78.8%). The sensitivity of ultrasound examination was good to high for fixity of the right and left ovaries, uterosacral ligaments, retrocervix and rectovaginal space; and low for the anterior and lateral parametria, vagina, bladder and bowel. Clinical examination had good to high specificity for fixity of the left ovary, anterior parametrium, right uterosacral ligament, retrocervix and vagina; and low specificity for fixity of the right ovary, lateral parametrium, left uterosacral ligament and rectovaginal space. The sensitivity of clinical examination was good for the uterosacral ligaments and rectovaginal space, and low for the remaining parameters. CONCLUSION: Ultrasound examination provided good specificity for all the parameters, but sensitivity was low for the anterior and lateral parametria. Clinical examination provided good specificity for the anterior and posterior parametria, but sensitivity was low for the anterior and lateral parametria. Further prospective studies are needed to validate this methodology and confirm the results.

INTRODUCTION: Myeloid sarcoma (MS) is a mass-forming proliferation of myeloid blasts. Frequently, it arises as blast phase of pre-existing myeloproliferative, myelodysplastic disorders or consequent to bone marrow transplant. Its molecular characterization has become an increasingly important requirement for the diagnostic definition of this solid leukemia. CASE PRESENTATION: Our case report concerns an MS arising in the breast of a woman with a previous diagnosis of JAK2-mutated essential thrombocythemia (Val617Phe exon 14p) mimicking, on histology, a lobular carcinoma of the breast. The immunohistochemical study of the neoplasm provided the key that solved the diagnostic doubt and the immunohistochemical evaluation of NPM protein expression, which turn out to be negative, provided a clear indication on the molecular status and prognosis of the disease. A year later, the neoplasm relapsed in the pelvic area. DISCUSSION: This diagnostic challenge led us to review the literature of the past 10 years concerning MS of the breast. To the best of our knowledge, this was the first case of MS of the breast occurring in a patient with a history of essential thrombocythemia and recurred in the pelvic region.

Artificial intelligence is finding several applications in healthcare settings. This study aimed to report evidence on the effectiveness of artificial intelligence application in obstetrics. Through a narrative review of literature, we described artificial intelligence use in different obstetrical areas as follows: prenatal diagnosis, fetal heart monitoring, prediction and management of pregnancy-related complications (preeclampsia, preterm birth, gestational diabetes mellitus, and placenta accreta spectrum), and labor. Artificial intelligence seems to be a promising tool to help clinicians in daily clinical activity. The main advantages that emerged from this review are related to the reduction of inter- and intraoperator variability, time reduction of procedures, and improvement of overall diagnostic performance. However, nowadays, the diffusion of these systems in routine clinical practice raises several issues. Reported evidence is still very limited, and further studies are needed to confirm the clinical applicability of artificial intelligence. Moreover, better training of clinicians designed to use these systems should be ensured, and evidence-based guidelines regarding this topic should be produced to enhance the strengths of artificial systems and minimize their limits.

Background: Maternal nutrition represents a critical risk factor for adverse health outcomes in both mother and offspring. We aimed to investigate associations between maternal nutritional habits, biomarker status, and pregnancy outcome among Italian healthy normal-weight pregnancies. Methods: Multicenter prospective cohort study recruiting Italian healthy normal-weight women with singleton spontaneous pregnancies at 20 ± 2 weeks (T1) in Milan and Naples. All patients underwent nutritional evaluations by our collecting a 7-day weighed dietary record at 25 ± 1 weeks (T2) and a Food Frequency Questionnaire at 29 ± 2 weeks (T3). Maternal venous blood samples were collected at T3 to assess nutritional, inflammatory and oxidative biomarker concentrations (RBCs folate, vitamin D, hepcidin, total antioxidant capacity). Pregnancy outcomes were collected at delivery (T4). General linear models adjusted for confounding factors were estimated to investigate associations between maternal dietary pattern adherence, nutrient intakes, biomarker concentrations and delivery outcomes. Results: 219 healthy normal-weight pregnant women were enrolled. Vitamin D and RBCs folate concentrations, as well as micronutrient intakes, were consistently below the recommended range. In a multi-adjusted model, maternal adherence to the most prevalent 'high meat, animal fats, grains' dietary pattern was positively associated with hepcidin concentrations and negatively associated with gestational age at delivery in pregnancies carrying female fetuses. Hepcidin plasma levels were further negatively associated to placental weight, whereas vitamin D concentrations were positively associated to neonatal weight. Conclusions: A high adherence to an unbalanced 'high meat, animal fats, grains' pattern was detected among Italian normal-weight low-risk pregnancies, further associated with maternal pro-inflammatory status and gestational age at delivery. This evidence underlines the need for a dedicated nutritional counseling even among low-risk pregnancies.

Background: Although current guidelines recommend that mothers with suspected or confirmed SARS-CoV-2 infection should be encouraged to initiate and continue breastfeeding, up-to-date literature shows conflicting data regarding breastfeeding experiences in infected women. This survey aimed to report on the psychological impact of SARS-CoV-2 infection on breastfeeding practice and medical counselling in a single tertiary center in Southern Italy. Methods: One-hundred breastfeeding women with SARS-CoV-2 infection at delivery were given an anonymous questionnaire regarding breastfeeding and women's perception of the impact of COVID-19 on breastfeeding. Results: 75% of women reported they had difficulty breastfeeding; among them, 66 (66%) declared that separation from their babies after delivery affected their ability to breastfeed. Incidence of reported difficulties in breastfeeding was higher in women who underwent caesarean section compared to women with vaginal delivery (56/65, 86.2% vs. 19/35, 54.3%, χ2 = 12.322, p < 0.001) and in women with a hospital stay of more than 5 days (48/57, 84.2% vs. 23/37, 62.2%, χ2 = 5.902, p = 0.015). Furthermore, the incidence of difficulties in breastfeeding was higher in women who subsequently decided to use exclusively infant formula compared to women who mixed maternal milk with infant formula and women who breastfed exclusively with maternal milk (48/49, 98% vs. 20/25, 80% vs. 7/26, 26.9%, χ2 = 46.160, p < 0.001). Conclusions: Our survey highlights the importance of healthcare support and information on hygiene practices to decrease the perceived stress related to breastfeeding for infected mothers under restrictions, especially in women undergoing cesarean section and with a long hospital stay.

Purpose: The aim of our study was to identify maternal characteristics of women who are responsive to the second application of vaginal dinoprostone in a cohort of patients with a low Bishop Score. Secondarily, we compared the outcome of the patients' response to a single application to that of the women's response to a double application.Materials and methods: This was a retrospective observational cohort study. Patients undergoing preinduction of labor with dinoprostone 10mg controlled-release vaginal device were included.Results: Among 216 included patients, 192 women (88.9%) achieved a cervical ripening after a single application of dinoprostone, while 24 (11.1%) required a second application. Patients notresponding to the first application of dinoprostone had a significantly higher body mass index (27.4 ± 6.7 kg/m2 vs 24.9 ± 5.2 kg/m2; p < 0.05) and a significant increase in gestational weight gain (14 ± 5.2 kg vs 11.6 ± 6.1; p < 0.005). Double application of dinoprostone resulted in spontaneousdelivery in 58.4% of cases, but it was related to poorer neonatal outcome, compared to a single application.Conclusions: Obese women, not responding to the first application of dinoprostone could respond to the second application of this vaginal prostaglandin. However, data related to the use of a double application are still very limited to recommend its use as a standardized procedurefor not responsive patients.

Singleton pregnancies obtained by assisted reproductive technology (ART) are at increased risk of adverse pregnancy outcome. Aim of this pilot study was to compare maternal hemodynamic profile in ART and spontaneous singleton pregnancies. Patients were enrollered during a third trimester routine obstetric examination. Maternal haemodynamic assessment was carried out by a single trained operator using an UltraSonic Cardiac Output Monitor in standardized conditions. Our pilot data suggests that women conceived after ART may have significantly lower Cardiac Output and significantly higher Systemic Vascular Resistance when compared to those conceiving spontaneously. These differences, if confirmed in larger studies, might explain the increased prevalence of adverse outcome, especially hypertensive disorders of pregnancy, in singleton ART pregnancies.

OBJECTIVE: We aimed to compare the haemodynamic profiles of obese and non-obese pregnant women, alongside describing the haemodynamic changes that occur in hypertensive disorders of pregnancies with an Appropriate for Gestational Age Fetus (HDP-AGA) beyond 34 weeks' gestation. STUDY DESIGN: In this prospective case-control study, maternal haemodynamic assessment was carried out by a trained operator using an UltraSonic Cardiac Output Monitor during a routine clinical assessment after 34 weeks of gestation. Indexed and non-indexed parameters were evaluated. MAIN OUTCOME MEASURES: Maternal hemodynamic parameters. RESULTS: Obese and non-obese women did not differ for non-indexed parameters (Cardiac Output, Stroke Volume, Systemic Vascular Resistance). Using indexed parameters, corrected for Body Surface Area, obese women presented significantly lower Cardiac Index z-score (-0.23 ± 0.5 vs 0.26 ± 1.2; p = 0.004), Stroke Volume Index z-score (-0.27 ± 0.8 vs 0.31 ± 1.0; p < 0.0001) and significantly higher Systemic Vascular Resistance Index (0.16 ± 0.8 vs -0.36 ± 0.7; p < 0.0001). In obese women, HDP-AGA (n = 19) had significantly higher Systemic Vascular Resistance Index z-score (1.26 ± 1.7 vs 0.16 ± 0.8; P = 0.009) and significantly lower Stroke Volume Index (-0.68 ± 0.8 vs -0.27 ± 0.8; 0.049). CONCLUSION: Using indexed parameters, differences in haemodynamic profiles between obese and non obese women can be highlighted. Obese women seem to present a cardiac maladapation to the pregnancy (reduced cardiac index and stroke volume and increased vascular resistance) that could explain the increased risk of complications in this subgroup.

Vitamin D is an important nutrient involved in many fundamental health outcomes. However, its influence on female reproductive function remains ambiguous. Cholecalciferol seems to have a role in the reproductive processes and in the patients affected by polycystic ovary syndrome, endometriosis, uterine myomas and premature ovarian failure. Moreover, it may play an important role in the assisted reproductive techniques, given that it is capable of influencing oocyte quality, but also an adequate preparation of the endometrium for embryonic implantation. Although promising, available evidence is based on a limited number of in vitro, in vivo and clinical studies. We provide an overview of the association between vitamin D and female infertility reporting the most recent data published in the literature. Nevertheless, properly randomised clinical trials are mandatory to achieve more conclusive results about the promising role of vitamin D in the management of female assisted reproduction.

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.
