Active clinical trials for "Congenital Abnormalities"

This prospective nested case-control study aims to examine the effects of blood vitamin B levels in first-trimester pregnant women on the pregnancy outcomes

The DEEP cohort is the first population-based cohort of pregnant population in China that longitudinally documents drug uses throughout the pregnancy life course and adverse pregnancy outcomes.

The objective of this randomized cross-over design was to investigate the fetal well-being and maternal glycemic response to an acute bout of aerobic high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) with pregnant individuals.

The purpose of this study is to test and evaluate the Preparing Heart and Mind™ (PHM™) patient engagement pathway as a nurse-guided intervention to lower psychological distress and enhance caregiving competencies among mothers/birthing persons and their caregiving partners after a major fetal anomaly diagnosis.

The Fontan Education Study is a cluster randomized controlled trial evaluating the impact of a novel education program in combination with usual care, versus usual care alone, on preparing parents of children undergoing Fontan surgery for the challenges of the postoperative course.

Many variables measured in critically ill patients have been used to estimate severity of disease, prognosticate morbidity and mortality, evaluate costs of treatment, and finally indicate specific treatment and monitor the adequacy of treatment and its timing. It is unlikely that one measurement can replace all of these, but in the remainder of this manuscript the investigators will show that lactate levels may come close. Although in our mind strongly linked to tissue hypoxia, lactate levels follow many more metabolic processes not related to tissue hypoxia and, therefore, subject to many disturbances found in various clinical situations

Apparently balanced chromosomal rearrangement (ABCR) associated with an abnormal phenotype is a rare but problematic event. It occurs in 6% of de novo reciprocal translocations and 9% of de novo inversions. Abnormal phenotype, including intellectual disability and / or multiple congenital anomalies (ID/MCA) may be explained either by associated cryptic genomic imbalances detectable by array-CGH or by gene disruption at the breakpoint. However, breakpoint cloning using conventional methods (i.e., fluorescent in situ hybridization (FISH), Southern blot) is often laborious and time consuming and cannot be performed routinely. Without complete investigation of these rearrangements, genetic counseling is a real challenge. Recently, the investigators and others showed that Next-Generation Sequencing (NGS) is a powerful and rapid technique to characterize ABCR breakpoints at the molecular level. The ANI project (ABCR NGS ID) aims at characterizing at the molecular level ABCR in 55 patients presenting with intellectual disability and/or multiple congenital anomalies (ID/MCA) using NGS. The investigators make the hypothesis that ABCR account for the patient phenotype, either by gene disruption or position effect, since genomic imbalance would have been previously excluded by array-Comparative Genomic Hybridization (CGH). The ANI project is a 3-year-long study that will be conducted by a consortium of 21 partners, including 19 french hospital cytogenetics laboratories, a research team (TIGER), and a cellular biotechnology center. Patients will be recruited by each Cytogenetics laboratory. ABCR breakpoints will be molecularly characterized by NGS and a first bio-informatics analysis. The results will be verified by amplification of junction fragments by polymerase Chain Reaction (PCR) followed by Sanger sequencing, allowing the localization of breakpoints at the base-pair level. In some complex cases, FISH experiment will be necessary to clarify the results. A second bio-informatics analysis will then determine breakpoints' characteristics (sequence, repeated elements, gene and regulatory elements). Finally, for each breakpoint, gene expression studies will be performed including the gene disrupted by the breakpoint and two neighboring genes. All these data, together with those already available in the literature and databases will be integrated to determine if the gene could account for the patient's phenotype, allowing an appropriate genetic counseling. This project will identify new candidate genes involved in ID and developmental anomalies. It will also contribute to the development and evaluation of NGS as a diagnostic tool for ABCR and ID/MCA. It will also allow unraveling mechanisms and functional consequences of ABCR, in particular in term of position effect. In conclusion, the ANI project will contribute to the improvement of diagnostic management and genetic counseling of patients with ID/MCA and ABCR. It will also contribute to the understanding of ABCR physiopathology and to the unraveling of pathway involved in development and brain function, thus improving genetic counseling for ID/MCA patients in general.

The purpose of this study is to determine the safety profile and probable benefit of the Ellipse Technologies Inc. MAGEC System in subjects with early onset spinal deformity associated with thoracic insufficiency syndrome.

Congenital malformations rate is about 3% in France. There are already 5 registries in France, covering about 16% of French births: Paris Registry, (about 38 000 births /year), Alsace Registry, (about 23 000 births/year), Rhône-Alpes Registry, (about 56 000 births/year), Auvergne Registry, (about 14 000 births/year), and la Réunion Registry. The aim of malformation registries is to carry out epidemiologic surveillance of congenital anomalies. The objectives are mainly to provide essential epidemiologic information on congenital anomalies, to facilitate the early warning of teratogenic exposures, to act as an information and resource centre regarding clusters, to provide data for research related to the causes and prevention of congenital anomalies. A previous study was carried out in Brittany in 2008-2009, by the perinatal network of Ille et Vilaine, in collaboration with two research teams (Inserm U1085 and Inserm U 936), to record all cases of 4 types of congenital anomalies: congenital heart disease, spina bifida, diaphragmatic hernia and hypospadia. The results showed prevalence rates similar to those observed by Eurocat for spina bifida and diaphragmatic hernia, but a higher prevalence regarding congenital heart diseases and hypospadia. In this study the investigators could not determine whether this was due to a real higher frequency or to a particular exhaustiveness in the recording methodology. There are hypothesis about the role of intrauterine exposure to pesticides, known as endocrine disruptors, and the risk of congenital genital anomalies. Brittany is an intensive agricultural area, and it is thus worth studying the impact of pesticides exposure on congenital anomalies. There are also hypothesis on the impact of occupational exposure to solvents on congenital anomalies (Garlantezec 2009), and on the role of alcohol exposure (which concerns about 8% pregnant women in France) on oro-facial clefts and congenital heart diseases. The Registry of congenital anomalies in Brittany was set up in 2010. The main aim is to study the impact of intra-uterine exposure to solvents, pesticides and alcohol on the risk of congenital malformations diagnosed at births, by measuring the exposure both directly in meconium, and indirectly by questionnaires. Secondary objectives are to study other risk factors such as medicine intake, pregnancy illness…

Context: Chest wall deformities in children are relatively common. One such deformity, known as Pectus Excavatum (PE), involves a concavity of the chest and is the most frequent of these abnormalities - present in approximately 1 out of every 400-1000 births. This deformity is often a cosmetic problem for affected individuals. When severe, PE can also be associated with cardiopulmonary compromise. Treatment of PE involves surgical correction. There are several potential methods for correcting PE. In the past the most common repair involved an open procedure which involves excision and reshaping of the ribcage. More recently a minimally invasive procedure has been adopted involving the placement of a stainless steel or titanium bar underneath the sternum to reshape the chest wall. This procedure, commonly known as the Nuss procedure, carries with it significant post-operative pain management problems. In fact, the pain issues after Nuss procedure may be more significant than after open repair. The quality of postoperative pain control in these cases has been shown to affect several measurable objective outcomes during hospitalization including capacity for deep breathing, early mobilization, ambulation, and length of hospital stay. Epidural analgesia (EA) has been one of the standard methods for managing pain in the early postoperative period after PE repair. Unfortunately severe pain may persist after the removal of an epidural catheter resulting in a difficult "transition" period just prior to discharge from the hospital. In addition reports of neurological injury after epidural analgesia for Nuss procedures have appeared. In light of these issues, many institutions have opted for alternative methods of pain control including peripheral nerve blocks, patient controlled analgesia, and wound catheters. There remains significant debate as to which pain control methodology is best. There is little consistent data available on pain control or outcomes that occur after EA is stopped. Moreover there is reluctance in any one institution to trial or randomize patients to a variety of treatment modalities. For all of these reasons, investigators are proposing participation in a multi-institutional data sharing project concerning the repair of EA in which participating centers will collaborate to better understand the outcomes of perioperative care for patients undergoing correction of this problem.
