MOTIVATION: The carotid intima-media thickness (cIMT) is an important biomarker for cardiovascular diseases and stroke monitoring. This study presents an intelligence-based, novel, robust, and clinically-strong strategy that uses a combination of deep-learning (DL) and machine-learning (ML) paradigms. METHODOLOGY: A two-stage DL-based system (a class of AtheroEdge™ systems) was proposed for cIMT measurements. Stage I consisted of a convolution layer-based encoder for feature extraction and a fully convolutional network-based decoder for image segmentation...

Background: Congenital diaphragmatic hernia (CDH) is a congenital anomaly with high mortality and morbidity mainly due to pulmonary hypoplasia and hypertension. Temporary fetal tracheal occlusion to promote prenatal lung growth may improve survival. Entrapment of lung fluid stretches the airways, leading to lung growth. Methods: Fetal endoluminal tracheal occlusion (FETO) is performed by percutaneous sono-endoscopic insertion of a balloon developed for interventional radiology...

Germline variants that affect function are found in seven genes of the BAF chromatin-remodeling complex. They are linked to a broad range of diseases that, according to the gene affected, range from non-syndromic or syndromic neurodevelopmental disorders to low-grade tumors and malignancies. In the current meta-analysis, we evaluate genetic and clinical data from more than 400 families and 577 patients affected by BAF germline alterations. We focus on SMARCB1, including 43 unpublished patients from the EU-RHAB registry and our institution...

OBJECTIVE: To examine the effect of first trimester screening for preeclampsia (PE) on the prediction of small for gestational age (SGA) neonates and the effect of prophylactic use of aspirin on the prevention of SGA. METHODS: The data for this study were derived from two multicentre studies. In SPREE we investigated the performance of screening for PE by a combination of maternal characteristics and biomarkers at 11-13 weeks' gestation. In ASPRE women with singleton pregnancies identified by combined screening as being at high risk for preterm-PE (>1 in 100) participated in a trial of aspirin (150 mg/day from 11 to 14 until 36 weeks' gestation), compared to placebo...

OBJECTIVE: To develop fetal and neonatal population weight charts. The rationale for this objective is that while reference ranges of estimated fetal weight (EFW) are representative of the whole population, the traditional approach of deriving birth-weight (BW) charts is misleading because a high proportion of babies born preterm arises from pathological pregnancies. We propose that the reference population for BW charts, as in the case of EFW charts, should be all babies at a given gestational age including those still in utero...

The tumor-shed antigen CA125 has recently been found to bind certain monoclonal antibodies (mAbs) and suppress immune-effector mediated killing through perturbation of the Fc domain with CD16a and CD32a Fc-γ activating receptors on immune-effector cells. Amatuximab is a mAb targeting mesothelin whose mechanism of action utilizes in part antibody-dependent cellular cytotoxicity (ADCC). It is being tested for its therapeutic activity in patients with mesothelioma in combination with first line standard-of-care...

Significant improvements in automated image analysis have been achieved in recent years and tools are now increasingly being used in computer-assisted syndromology. However, the ability to recognize a syndromic facial gestalt might depend on the syndrome and may also be confounded by severity of phenotype, size of available training sets, ethnicity, age, and sex. Therefore, benchmarking and comparing the performance of deep-learned classification processes is inherently difficult. For a systematic analysis of these influencing factors we chose the lysosomal storage diseases mucolipidosis as well as mucopolysaccharidosis type I and II that are known for their wide and overlapping phenotypic spectra...

OBJECTIVES: To assess whether in a cohort of patients with small for gestational age (SGA) foetuses with estimated fetal weight ≤10th percentile, maternal hemodynamics, fetal biometry and Dopplers at presentation, can predict the subsequent development of abnormal fetal Dopplers or delivery with birthweight <3rd percentile. METHODS: The study population comprised of 86 singleton pregnancies with SGA fetuses presenting at a median gestational age of 32 (range 26-35) weeks...

Cell-free DNA analysis is becoming adopted for first line aneuploidy screening, however for most healthcare programs, cost and workflow complexity is limiting adoption of the test. We report a novel cost effective method, the Vanadis NIPT assay, designed for high precision digitally-enabled measurement of chromosomal aneuploidies in maternal plasma. Reducing NIPT assay complexity is achieved by using novel molecular probe technology that specifically label target chromosomes combined with a new readout format using a nanofilter to enrich single molecules for imaging and counting without DNA amplification, microarrays or sequencing...

AIM: We investigated the natural history of fetal ovarian cysts to estimate the risk of torsion according to size. METHODS: Cases were identified from 1/1/2000 until 1/1/2015. Data were collected pre- and postnatally on cyst size and sonographic features until an outcome of surgery, torsion, or resolution. Fisher's exact test for categorical data and logistic regression for continuous data were used to test the significance of size on torsion; P value <0.05 was considered significant...

BACKGROUND: Preeclampsia is a major pregnancy complication with adverse short- and long-term implications for both the mother and baby. Screening for preeclampsia at 11-13 weeks' gestation by a combination of maternal demographic characteristics and medical history with measurements of biomarkers can identify about 75% of women who develop preterm preeclampsia with delivery at <37 weeks' gestation and 90% of those with early preeclampsia at <32 weeks, at a screen-positive rate of 10%...

Slipped capital femoral epiphysis (SCFE) is a fracture that results from displacement of the proximal femoral epiphysis from the femoral neck. SCFE can be caused by various endocrinopathies that lead to bone weakening in both adult and pediatric patients. We report a rare case of suprasellar germinoma presenting with SCFE in an 11-year-old female patient. The findings of this case further support the need to consider pituitary lesions as the underlying cause of endocrine deficiences leading to SCFE.

Preeclampsia is one of the most dangerous pregnancy complications, and the leading cause of maternal and perinatal mortality and morbidity. Although the clinical symptoms appear late, its origin is early, and hence detection is feasible already at the first trimester. In the current study, we investigated the abundance of circulating small non-coding RNAs in the plasma of pregnant women in their first trimester, seeking transcripts that best separate the preeclampsia samples from those of healthy pregnant women...

INTRODUCTION: The use of a venoactive drug is considered an important component of medical treatment of chronic venous disease (CVD), although the efficacy of certain venoactive drugs (VADs) on one or more individual leg symptoms or signs may have not been extensively studied to justify a strong recommendation in guidelines on CVD. The aim of this systematic review and meta-analysis was to study the effectiveness of the micronized purified flavonoid fraction (MPFF, Daflon®) across the spectrum of defined venous symptoms, signs, quality of life (QoL) and treatment assessment by the physician...
