Induced abortion and COVID-19 as contributing factors to declining fertility in Sardinia.

OBJECTIVES: Decreasing fertility implies considerable public health, societal, political, and international consequences. Induced abortion (IA) and the recent COVID-19 pandemic can be contributing factors to it but these have not been adequately studied so far. The purpose of this paper is to explore the relation of IA incidence and the COVID-19 pandemic to declining rates of delivery, as per our Sardinian experience. METHODS: We analyzed the registered data from the official Italian statistics surveys of deliveries and IA in the last 10 years from 2011 to 2020 in Sardinia. RESULTS: A total of 106,557 deliveries occurred and a progressive decrease in the birth rate has been observed. A total of 18,250 IA occurred and a progressive decline has been observed here as well. The ratio between IA and deliveries remained constant over the decade. Between 2011 and 2019 a variation of -4.32% was observed for IA while in the last year, during the COVID-19 pandemic the decrease of the procedures was equal to -12.30%. For the deliveries, a mean variation of the -4.8% was observed between the 2011 and the 2019 while in the last year, during the COVID-19 pandemic the decrease was about -9%. Considering the about 30% reduction of live births between 2011 and 2020, there is an almost proportional reduction in IA. CONCLUSIONS: Public policy responses to decreasing fertility, especially pronatalist ones, would be provided with evidence base about trends in delivery and IA and women's decision making.

Metabolomics Analysis of Amniotic Fluid in Euploid Foetuses with Thickened Nuchal Translucency by Gas Chromatography-Mass Spectrometry.

Persistence of a fetal thickened nuchal translucency (NT), one of the most sensitive and specific individual markers of fetal disorders, is strongly correlated with the possibility of a genetic syndrome, congenital infections, or other malformations. Thickened NT can also be found in normal pregnancies. Several of its pathophysiological aspects still remain unexplained. Metabolomics could offer a fresh opportunity to explore maternal-foetal metabolism in an effort to explain its physiological and pathological mechanisms. For this prospective case-control pilot study, thirty-nine samples of amniotic fluids were collected, divisible into 12 euploid foetuses with an enlarged nuchal translucency (>NT) and 27 controls (C). Samples were analyzed using gas chromatography mass spectrometry. Multivariate and univariate statistical analyses were performed to find a specific metabolic pattern of >NT class. The correlation between the metabolic profile and clinical parameters was evaluated (NT showed an R2 = 0.75, foetal crown-rump length showed R2 = 0.65, pregnancy associated plasma protein-A showed R2 = 0.60). Nine metabolites significantly differing between >NT foetuses and C were detected: 2-hydroxybutyric acid, 3-hydroxybutyric, 1,5 Anydro-Sorbitol, cholesterol, erythronic acid, fructose, malic acid, threitol, and threonine, which were linked to altered pathways involved in altered energetic pathways. Through the metabolomics approach, it was possible to identify a specific metabolic fingerprint of the fetuses with >NT.

Deep Infiltrating Endometriosis: Comparison Between 2-Dimensional Ultrasonography (US), 3-Dimensional US, and Magnetic Resonance Imaging.

OBJECTIVES: To evaluate the diagnostic accuracy of 2-dimensional (2D) and 3-dimensional (3D) transvaginal ultrasonography (US) in comparison with magnetic resonance imaging (MRI) for identification of deep infiltrating endometriosis. METHODS: In this prospective observational study, 159 premenopausal women who underwent surgery for a clinical suspicion of deep infiltrating endometriosis were prospectively enrolled. All women underwent 2DUS, 3DUS, and MRI. The following 3 locations of deep endometriosis were considered: (1) intestinal; (2) other posterior lesions (retrocervical septum, rectovaginal septum, uterosacral ligaments, and vaginal fornix); and (3) anterior. The sensitivity, specificity, positive predictive value, and negative predictive value of 2D and 3D transvaginal US in comparison with MRI were determined. RESULTS: Intestinal deep infiltrating endometriosis was identified by 2DUS in 56 of 66 patients, by 3DUS in 59 of 66, and by MRI in 61 of 66. A receiver operating characteristic curve analysis showed optimal results for 2DUS, 3DUS, and MRI (areas under the curve, 0.86, 0.915, and 0.935, respectively) with a statistically significant difference between 2DUS and MRI (P = .0103), even when the 95% confidence interval showed an overlap. Other posterior deep infiltrating endometriosis was identified by 2DUS in 55 of 75 patients, by 3DUS in 65 of 75, and by MRI in 66 of 75. A receiver operating characteristic curve analysis showed very good results for 2DUS, 3DUS, and MRI (areas under the curve, 0.801, 0.838, and 0.857) with no statistically significant differences. In the 12 women with deep infiltrating endometriosis in the anterior location, the nodules were correctly identified by 2DUS in 3 of 12 patients, by 3DUS in 5 of 12, and by MRI in 6 of 12. CONCLUSIONS: Our results seem to suggest that there is a statistically significant difference between 2DUS and MRI for the intestinal location of deep infiltrating endometriosis, whereas no differences were found among the techniques for the other locations.

Reproducibility of the International Endometrial Analysis Group Color Score for Assigning the Amount of Flow Within the Endometrium Using Stored 3-Dimensional Volumes.

OBJECTIVES: To estimate intraobserver and interobserver reproducibility for assigning an International Endometrial Tumor Analysis (IETA) group color score for endometrial vascularization on color Doppler imaging. METHODS: Sixty-eight endometrial 3-dimensional volumes from endometrial color Doppler assessments of women with different endometrial disorders were evaluated by 8 different examiners (4 skilled examiners and 4 obstetric and gynecologic trainees). One skilled examiner who did not participate in the assessments selected the 68 volumes from a database to select a balanced number of each IETA score. Each examiner evaluated the 68 endometrial volumes to assign the IETA color score (1, absence of vascularization; 2, low vascularization; 3, moderate vascularization; or 4, abundant vascularization) using tomographic ultrasound imaging. The analysis was repeated 4 weeks later, and interobserver and intraobserver reproducibility was analyzed by calculating the weighted κ index. The second of the measurements made by each observer was used to estimate interobserver reproducibility. RESULTS: The intraobserver reproducibility was very good for all examiners, with a weighted κ index ranging from 0.84 to 0.91. The interobserver reproducibility was good or very good for all estimated comparisons, with a weighted κ index ranging from 0.77 to 0.96, regardless of experience level. CONCLUSIONS: The reproducibility of assigning the IETA color score for assessing endometrial vascularization using 3-dimensional volumes is good or very good regardless of the experience of the examiner.

Malignancy risk of sonographically benign appearing purely solid adnexal masses in asymptomatic postmenopausal women.

OBJECTIVE: To assess the natural history of benign appearing purely solid ovarian lesions in asymptomatic postmenopausal women. METHODS: Retrospective observational cohort study comprising 99 women (mean age, 58.2 years, ranging from 50 to 77 years) diagnosed as having a purely solid ovarian lesion at transvaginal ultrasound between April 2001 and October 2015. Inclusion criteria were as follows: asymptomatic postmenopausal women with a well-defined purely solid ovarian lesion with International Ovarian Tumor Analysis color score 1 or 2, without ascites and/or signs of carcinomatosis. Clinical, sonographic, biochemical (CA-125), and histologic data (in case of surgery) were retrieved for analysis. Patients who were managed conservatively were assessed by transvaginal sonography every 6 months for a minimum of a year. In case of bilateral lesions we used the largest one for analysis. RESULTS: Five women (5.1%) had bilateral lesions. Mean size of the lesion was 2.9 cm (range, 1.0-7.8 cm). Most lesions were homogeneous (96.0%). Acoustic shadowing was present in 59.6% of cases. International Ovarian Tumor Analysis color score was 1 in 77.8% and 2 in 22.2% of the cases, respectively. Median CA-125 was 10.8 IU/mL (range, 3.0-403.0 IU/mL). Forty-two women underwent surgery after diagnosis (histologic diagnoses were as follows: fibroma (n = 26), fibrothecoma (n = 5), dermoid (n = 3), Brenner tumor (n = 3), endometrioma (n = 2), thecoma (n = 1), primary invasive cancer (n = 2). One case of invasive cancer CA-125 was 403.0 IU/mL and in the other case CA-125 was 6.0 IU/mL. They both were stage 1. Fifty-seven women were managed with serial follow-up. With a median follow-up time of 36 months (range, 12-142 months) all these lesions had no change and women remain asymptomatic. Considering all 99 cases the risk of malignancy is 2% (95% CI, 0.1-7.5). CONCLUSIONS: The risk of malignancy of benign appearing purely solid adnexal masses in asymptomatic postmenopausal women is low. Conservative management of these lesions might be an option.

[Analysis of the accreditation process JACIE Transplant Program Businco]. / Analisi del processo di Accreditamento JACIE del Programma Trapianti Businco.

INTRODUCTION: The Businco Transplant Program undertook the JACIE standards accreditation process since January 2010. The process is here analyzed by a descriptive-exploratory quantitative study to verify the hypothesis that accreditation according to the standard JACIE improves health professionals performance and organization output. METHODS: An analysis was performed before starting the whole process. An analysis of the planning, programming and implementation of actions was carried out. Data analysis focuses on the organizational and structural changes, training, and preparation of documentation, implementation and verification of objectives achievement. The data refer to the period between January 2010 and October 2012. RESULTS: A dedicated team was set up, an implementation plan and process map was developed. A Quality Management System was also implemented. This included: risk management, audit and quality indicators. CONCLUSIONS: Despite the difficulties the JACIE accreditation process has been useful for integration and professional collaboration. Education of the staff has played a key role in the implementation of the whole system and in particular for the quality management system.

Past, present and future ultrasonographic techniques for analyzing ovarian masses.

Ultrasonography is today the method of choice for distinguishing between benign and malignant adnexal pathologies. Using pattern recognition several types of tumors can be recognized according to their characteristic appearance on gray-scale imaging. Color Doppler imaging should be used only to perform a semiquantitative color score or evaluate the flow location. International Ovarian Tumor Analysis group had standardized definitions characterizing adnexal masses and suggested the use of 'simple rules' in premenopausal women. Recently, the use of 3D vascular indices has been proposed but its potential use in clinical practice is debated. Also computerized aided diagnosis algorithms showed encouraging results to be confirmed in the future.

Reproducibility of two different methods for performing mean gray value evaluation of cyst content in endometriomas using VOCAL.

OBJECTIVE: To compare two different methods (manual sampling of the entire cyst and semi-automated spherical sampling from the central part of the cyst) for calculating the mean gray value (MGV) from the cystic content in endometriomas using virtual organ computer-aided analysis (VOCAL). METHODS: Forty-one volumes from histologically confirmed endometriomas were retrieved from our database and the volumes were analyzed to compare the MGVs obtained via the two modalities. In addition, to evaluate the reproducibility in a sample of 20 volumes, two different observers calculated the MGV from cyst content using VOCAL software. For each method, each examiner analyzed the volumes twice, 3 weeks apart, for assessment of intra-observer agreement. First, manual sampling of the internal contour of all the cysts was performed, and 1 week later semi-automated 2-cm sphere sampling from the central part of the cyst was carried out. In addition, the observers recorded the time spent performing each analysis. Inter- and intra-observer reproducibility was evaluated for each method using intra-class correlation coefficients (ICC). RESULTS: There was no difference in the mean MGV between manual sampling (22.211 ± 7.541) and the semi-automated modality of sampling (23.840 ± 8.621, p = 0.439). The correlation between manual and semi-automated sampling measurement was high (r = 0.92). According to the ICCs, there was no significant difference in interobserver reliability between manual sampling (0.931; 95 % CI, 0.824-0.973) and the semi-automated modality of sampling (0.924; 95 % CI, 0.809-0.970). Intra-observer reproducibility for both examiners was good (ICC > 0.94). Semi-automated measurements were obtained faster than those obtained by manual evaluation (p = 0.0001 for observer 1 and p = 0.083 for observer 2). CONCLUSIONS: Both methods seem to be reliable, but the semi-automated method using the sphere should be preferred because it is a less time-consuming procedure.
