Effects of Mediterranean Diet or Mindfulness-Based Stress Reduction during Pregnancy on Fetal Brain Development Detected by Neurosonography: A Secondary Analysis of a Randomized Clinical Trial (IMPACT BCN).

INTRODUCTION: We investigated whether structured maternal lifestyle interventions based on Mediterranean diet or stress reduction influence fetal-infant neurodevelopment detected by detailed fetal neurosonography and Ages and Stages Questionnaires 3rd edition (ASQ) at 12 months old. METHODS: This was a secondary analysis of a randomized clinical trial (2017-2020), including 1,221 singleton pregnancies at high risk for small-for-gestational age. Participants were randomized into three groups at 19-23 weeks' gestation: Mediterranean diet intervention, stress reduction program, or usual care. A detailed neurosonography was performed on 881 participants at mean (SD) 33.4 (1.1) weeks' gestation. Neurosonographic measurements were done offline. ASQ was performed on 276 infants at 1 year of corrected age. RESULTS: Biparietal diameter was similar among study groups. Mediterranean diet group fetuses had deeper insula (26.80 [1.68] versus 26.63 [1.75], mm, p = 0.02) and longer corpus callosum (42.98 [2.44] versus 42.62 [2.27], mm, p = 0.04), with a lower rate of suboptimal score infants in ASQ problem-solving domain (6.2 vs. 16.3%, p = 0.03). Stress reduction group fetuses had deeper insula (26.90 [1.75] versus 26.63 [1.75], mm, p = 0.04) and lower rates of suboptimal score infants in ASQ fine motor domain (4.3 vs. 12.8%, p = 0.04), compared to usual care group fetuses. CONCLUSION: Maternal structured intervention during pregnancy of the trial has the potential to modify offspring's neurodevelopment.

Automatic Deep Learning-Based Pipeline for Automatic Delineation and Measurement of Fetal Brain Structures in Routine Mid-Trimester Ultrasound Images.

INTRODUCTION: The aim of this study was to develop a pipeline using state-of-the-art deep learning methods to automatically delineate and measure several of the most important brain structures in fetal brain ultrasound (US) images. METHODS: The dataset was composed of 5,331 images of the fetal brain acquired during the routine mid-trimester US scan. Our proposed pipeline automatically performs the following three steps: brain plane classification (transventricular, transthalamic, or transcerebellar plane); brain structures delineation (9 different structures); and automatic measurement (from the structure delineations). The methods were trained on a subset of 4,331 images and each step was evaluated on the remaining 1,000 images. RESULTS: Plane classification reached 98.6% average class accuracy. Brain structure delineation obtained an average pixel accuracy higher than 96% and a Jaccard index higher than 70%. Automatic measurements get an absolute error below 3.5% for the four standard head biometries (head circumference, biparietal diameter, occipitofrontal diameter, and cephalic index), 9% for transcerebellar diameter, 12% for cavum septi pellucidi ratio, and 26% for Sylvian fissure operculization degree. CONCLUSIONS: The proposed pipeline shows the potential of deep learning methods to delineate fetal head and brain structures and obtain automatic measures of each anatomical standard plane acquired during routine fetal US examination.

Paget disease of the vulva an analysis of 24 cases.

Paget's disease can arise in the breast (mammary Paget disease) or in other locations (extramammary Paget disease) such as anogenital skin in both males and females (Paget disease of the vulva [PDV]). Underlying adenocarcinoma can be found in some cases. This study aims to report clinical aspects, surgical procedures, outcomes, and recurrences of patients with PDV.A retrospective chart review was conducted on patients with pathologically confirmed diagnosis of PDV managed at the Department of Obstetrics and Gynecology, University of Bari, and the "Giovanni Paolo II" National Cancer Institute in Bari, between 1998 and 2018.Records of 24 cases of PDV were examined. Median age of the patients at diagnosis was 69.3 (range 38-84), diagnosis of synchronous cancer was made in 2 cases and in 2 other cases of metachronous disease. Three patients had previously been diagnosed with other oncological diseases. All patients underwent surgery including wide local excision (6), simple vulvectomy (8), and extended vulvectomy (10). Lymphadenectomy was performed in 2 cases and reconstructions with advancement flaps in 7 cases. Four patients were found to have invasive disease and 1 had inguinal node involvement. Positive margins were found in 11 patients. Wound dehiscence and urethral stenosis were found in 4 and 1 case each. Eight recurrences (33.33%) were observed, regardless of positive surgical margins.PDV has a low rate of malignancy but a high rate of recurrence. It should be diagnosed early to avoid repeated surgery and to reduce symptoms and morbidity.
