OBJECTIVES: In the West Midlands Regional Genetic Service, cases of perinatal death with a possible genetic diagnosis are evaluated by the Perinatal Pathology Genetic Multidisciplinary Team (MDT). The MDT assessed autopsy findings and considered genomic assessments. The objective of this retrospective service evaluation was to determine the clinical utility of the MDT. This is the first evaluation since the introduction of whole genome and whole exome sequencing in routine clinical care...

OBJECTIVE: Anchoring the fetal membrane to the uterine wall via a novel suture delivery system could reduce the risk of preterm premature rupture of membranes (PPROM) after fetoscopic surgery. This study assesses the feasibility of using a novel device designed for minimally invasive suturing to anchor fetal membranes to the uterine wall and to close surgical defects after fetoscopy. METHODS: We tested the suturing device both ex vivo and in vivo. In the ex vivo studies, 12-French trocar defects were created with a fetoscope in five specimens of human uterine tissue with fetal membranes attached...

OBJECTIVE: Large-for-gestational-age (LGA) is associated with several adverse maternal and neonatal outcomes. Although many studies have found that early induction of labor (eIOL) in LGA reduces the incidence of shoulder dystocia (SD), no current guidelines recommend this particular strategy, due to concerns about increased rates of cesarean delivery (CD) and neonatal complications. The purpose of this study was to assess whether the timing of IOL in LGA fetuses affects maternal and neonatal outcomes in a single center; and to combine these results with the evidence reported in the literature...

OBJECTIVE: To compare the fetal cardiac functions between pregnant women with iron deficiency anemia (IDA) and healthy controls. METHODS: This single-center, prospective, case-control study was conducted at a tertiary hospital. A total of 150 patients, including 50 patients with IDA and 100 healthy pregnant women at 30-34 weeks of gestation, were included in the study. Of the patients with anemia, 20 had mild anemia, 18 had moderate anemia, and 12 had severe anemia...

OBJECTIVES: The aim is to evaluate the ability of the Assessment of Different NEoplasias in the adneXa model (ADNEX) and the International Ovarian Tumour Analysis (IOTA) two-step strategy to predict malignancy in adnexal masses detected in an outpatient low-risk setting, and to estimate the risk of complications in masses with benign ultrasound morphology managed with clinical and ultrasound follow-up. METHODS: This single center (Hospital Universitari Dexeus Barcelona) study was performed using interim data of the ongoing prospective observational IOTA phase 5 study...

BACKGROUND: First, a logistic regression model, based on maternal demographic characteristics and medical history and blood pressure at 11-13 weeks' gestation, can identify about 70% of women who develop future chronic hypertension (CH) in the three years following pregnancy, at screen positive rate of 10%. Second, at mid-gestation women who subsequently develop hypertensive disorders of pregnancy (HDP) have increased peripheral vascular resistance and mild cardiac functional and morphological alterations and these cardiovascular abnormalities persist for at least 2 years after delivery...

OBJECTIVES: During human pregnancy placental extravillous trophoblasts replace the vascular smooth muscle and elastic tissue within the walls of the uterine spiral arteries, thereby remodeling these arteries into distensible low resistance vessels to promote placental perfusion. The present study, determined whether B-flow/ spatio-temporal image correlation (STIC) M-mode ultrasonography provides an in vivo imaging method to digitally quantify spiral artery luminal distensibility, as a physiological index of spiral artery remodeling, during advancing stages of normal human pregnancy...

OBJECTIVE: This study aimed to externally and prospectively validate the International Ovarian Tumor Analysis (IOTA) Simple Rules (SRs), Logistic Regression model 2 (LR2) and Assessment of Different NEoplasias in the adneXa (ADNEX) in a Portuguese population, comparing them with operator subjective assessment (SA), Risk-of-Malignancy Index (RMI), as well as with each other. This study also aimed to retrospectively validate IOTA two-step strategy, using modified benign descriptors (MBDs) followed by the application of ADNEX in cases where MBDs were not applicable (MBDs + ADNEX)...

OBJECTIVES: Well-established clinical practice to assess progress in labor involves routine abdominal palpation and vaginal examination (VE). However, VE is subjective, poorly reproducible and painful for women. In this study, our aim is to evaluate the feasibility of systematically integrating transabdominal and transperineal ultrasound assessment of fetal position, psAOP, HPD and SCD to monitor labor progress in women undergoing induction of labor (IOL). We also aim at determining if ultrasound can reduce women's pain during examinations...

OBJECTIVE: To assess the diagnostic performance of transvaginal ultrasound (TVUS) for preoperative evaluation of lymph node metastasis in gynecological cancers. METHODS: A systematic review and meta-analysis was performed. All studies published between January 1990 to May 2023 evaluating the role of ultrasound for detecting lymph node metastasis (index test) in gynecological cancers, using histopathological analysis, as reference standard were included. Quality was assessed using QUADAS-2...

BACKGROUND: Women with hypertensive disorders of pregnancy (HDP) are at increased risk of developing hypertension and cardiovascular disease later in life. However, from studies so far, it is difficult to define whether this association reflects preexisting maternal cardiovascular risk or merely reflect a potentially causal relationship between HDP and later cardiovascular risk. OBJECTIVES: We performed detailed cardiovascular assessment in women at mid-gestation, prior to development of a HDP and at 2 years post-partum aiming to identify cardiovascular changes prior to development of HDP and to assess persistent cardiovascular alterations long after the HDP event...

OBJECTIVE: To determine the association of high middle cerebral artery peak systolic velocity (MCA-PSV) with fetal demise in donor twins among pregnancies complicated by twin-to-twin transfusion syndrome (TTTS) in the absence of twin anemia polycythemia sequence (TAPS). METHODS: This prospective cohort study included TTTS cases that underwent laser surgery between 2011 and 2022 at a single center. TAPS cases were excluded from the study. The primary objective was to explore the association of high MCA-PSV (>1...
