NCT ID: NCT06410391 Recruiting - Fetal Anomaly Clinical Trials

Fetal Brain Ultrasound

Start date: June 15, 2024
Phase:
Study type: Observational

The aim of our study is to determine the range of frontal horn sizes (both upside and downside) in healthy fetuses over gestation and to determine how far FHs are from the midline . Also to determine the range of cavum septi pellucidi and Corpus callosum sizes . Also, to determine whether the maternal body mass index (BMI) affects rates of visualized and non-visualized CSP and CC.

NCT ID: NCT05790473 Recruiting - Fetal Anomaly Clinical Trials

Artificial Intelligence Algorithm for the Screening of Abnormal Fetal Brain Findings at First Trimester Ultrasound Scan

AIRFRAME
Start date: May 1, 2023
Phase:
Study type: Observational

Visualization of the posterior fossa brain spaces, their spatial relationship and measurements can be obtained in the midsagittal view of fetal head, the same used for NT measurement (9), and plays an important role in the early diagnosis of neural tube defects, such as open spinal dysraphism (5), and posterior fossa anomalies, such as DWM or BPC (7). However, assessment of the fetal posterior fossa in the first trimester is still challenging due to several limitations including involuntary movements of the fetus and small size of the brain structures, causing difficulties for examination and misdiagnosis. Moreover, it is also operator-dependent for the acquirement of high-quality ultrasound images, standard measurements, and precise diagnosis. The use of new technologies to improve the acquisition of images, to help automatically perform measurements, or aid in the diagnosis of fetal abnormalities, may be of great importance for the optimal assessment of the fetal brain, particularly in the first trimester (10). Artificial intelligence (AI) is described as the ability of a computer program to perform processes associated with human intelligence, such as learning, thinking and problem-solving. Deep Learning (DL), a subset of Machine Learning (ML), is a branch of AI, defined by the ability to learn features automatically from data without human intervention. In DL, the input and output are connected by multiple layers loosely modeled on the neural pathways of the human brain. In the image recognition field, one of the most promising type of DL networks is represented by convolutional neural networks (CNN). These are designed to extract highly representative image features in a fully automated way, which makes them applicable to diagnostic decision-making. According to these observations, we propose a research project aimed to develop an ultrasound-based AI-algorithm, which is capable to assess the fetal posterior fossa structures during the first trimester ultrasound scan and discriminate between normal and abnormal findings through a fully automatic data processing.

NCT ID: NCT05785338 Completed - Ultrasound Clinical Trials

Trial Observationnal

CLEFTPALATDIAG
Start date: January 15, 2023
Phase:
Study type: Observational

The aim of this retrospective longitudinal study was to describe a key factor in the prenatal diagnosis of isolated cleft palate on the axial transverse view, in order to provide better understanding, detection and diagnosis of this anomaly.

NCT ID: NCT05764408 Completed - Fetal Anomaly Clinical Trials

Pannus Assistance Needed for Obstetric Ultrasound Studies

Start date: March 10, 2023
Phase: N/A
Study type: Interventional

The goal of this randomized controlled trial is to evaluate whether use of a pannus retractor adhesive improves fetal anatomic ultrasound examinations. The primary question it aims to answer is: • Does the use of a pannus retractor adhesive increase the rate of detailed anatomic survey completion, defined by satisfactory visualization of sixteen prespecified fetal anatomy views, for participants with a pannus and body mass index of at least 40 kg/m2?

NCT ID: NCT05655741 Completed - Genetic Disease Clinical Trials

Modified Delphi for Genomic Bereavement Care

Start date: October 28, 2022
Phase:
Study type: Observational

It is estimated that 1 in 4 pregnancies end in loss, be these early miscarriages, ectopic pregnancies, or later intrauterine losses for any reason. Genomics is a major part of pregnancy loss, and clinicians want to offer the best and most appropriate test available to women and their families, whilst ensuring that there is equity in the access to this testing, so that no family goes through a loss without the right support and information. Whilst there is limited information to inform professionals as to how to incorporate genomics into bereavement care there is a need to identify current expert consensus as to how this should be performed, in order to make recommendations for best practice.

NCT ID: NCT05527327 Completed - Obesity Clinical Trials

Pannus Retraction for Ultrasound Evaluation of the Obese Gravida: A Pilot Study

Start date: September 16, 2022
Phase: N/A
Study type: Interventional

Pregnancies complicated by obesity have an increased risk of multiple pregnancy complications, including structural fetal anomalies. Therefore, maternal obesity (BMI ≥30 kg/m2) is an indication for a detailed anatomic ultrasound examination. Ultrasound is a critical tool for the detection of congenital anomalies; however, obesity makes ultrasound examinations technically challenging. The primary objective of this ambidirectional cohort pilot study is to evaluate whether utilization of a pannus retractor is associated with increased rates of detailed anatomic ultrasound completion amongst pregnant patients with a body mass index (BMI) greater than or equal to 40 kg/m2. Retrospective data will be collected for 100 patients with a BMI of 40 kg/m2 or greater to assess the baseline rate of completion of 16 components of the detailed anatomic survey prior to the intervention. We plan to enroll 20 patients into a prospective pilot to the intervention arm. The intervention is placement of an adhesive medical device, the traxi® Panniculus Retractor (Laborie, Portsmouth, New Hampshire), which was developed for pannus retraction during cesarean section. Adequacy of anatomic ultrasound completion will be based upon 16 pre-defined views from the anatomic survey. Ultrasound completion rates from the prospective cohort of participants that undergo ultrasound evaluation using a pannus retractor will be compared to a historical cohort without pannus retractor use. We hypothesize that use of a pannus retractor for pregnant participants with BMI greater than or equal to 40 kg/m2 increases the rate of anatomical ultrasound completion.

NCT ID: NCT04897178 Not yet recruiting - Fetal Anomaly Clinical Trials

Machine Learning-based Anomaly Recognition System

MARS
Start date: June 1, 2021
Phase:
Study type: Observational

MARS is an artificial intelligence-powered system that aims at detecting common fetal anomalies during real-time obstetrics ultrasound. The current study comprises 2 stages: (1) The stage of model creation which will include retrospective collection of images from fetal anatomy scans with known diagnoses to train these model and test their diagnostic accuracy. (2) The stage of model validation through prospective application of this model to collected videos with known normal and abnormal diagnoses

NCT ID: NCT04174235 Completed - Fetal Anomaly Clinical Trials

Start date: January 14, 2016

NCT ID: NCT03795857 Completed - Fetal Anomaly Clinical Trials

Antenatal Palliative Care

SPAN
Start date: January 14, 2019
Phase:
Study type: Observational

In France, according to current legislation, termination of pregnancy could be performed without any upper gestational age limit, if there is a strong probability that the fetus will be affected by a particularly severe and incurable disease. When there is a lethal fetal diagnosis most of parents wish to terminate their pregnancy. However, and despite some medical resistance a few of them do wish to continue pregnancy. In these situations, palliative care seems to be a good way to prepare to welcome the child and surround him until death. The aim of the study is to describe parents' experience for a better understanding and a better care.
