Active clinical trials for "Congenital Abnormalities"

This is a national, prospective study designed to investigate the genetic etiologies of non-immune hydrops fetalis (NIHF) and other birth defects. At least half of prenatally diagnosed NIHF cases remain of unknown etiology after standard work up, and a substantial proportion of other birth defects remain of unknown etiology as well. The investigators are performing exome sequencing (ES) for the affected fetus or neonate in unexplained cases, as well as enrolling cases with a genetic explanation to represent the full spectrum of diseases underlying NIHF and other birth defects.

This study will assess the safety and performance of the GORE PV1 Device for replacement of the pulmonary valve and reconstruction of the Right Ventricular Outflow Tract (RVOT).

The comfort and fit of the residual limb within a prosthetic socket are of primary concern for many amputees. The residual limb is typically covered by nonbreathable and non-thermally conductive materials that can create a warm and ultimately moist environment. The investigators have developed a silicone liner approach to passively conduct heat from the skin using thermally conductive elastomers. A technology that can provide thermal control while retaining adequate suspension, weight, and other prosthetic characteristics would benefit many prosthesis wearers.

A good understanding of the principles of balance is vital to achieve optimal outcomes when treating spinal disorders. A complex interaction of the neuromotor system and muscular recruitment is necessary for ergonomic balance and deliberate displacement of the human body. Sagittal plane misalignment in spinal deformities challenges balance mechanisms used for maintenance of an upright posture. The occurrence of postoperative complications after spinal deformity correction like under-correction of sagittal misalignment, postoperative reciprocal changes in thoracic kyphosis, proximal junctional kyphosis and failure of instrumentation are possibly due to the current state-of-the art inadequate diagnostic work-up. Investigators do not fully understand the roll of vision and exact strategy of recruitment of neuromuscular units (trunk, pelvis, lower limbs) in patients with sagittal plane misalignment during standing and walking. To understand this, a dynamic evaluation of individuals with spinal deformities is needed. Currently there is only very little research performed in the field of clinical balance tests and instrumented movement analysis in patients with spinal deformity. The challenge for future studies is to further unravel the relation between trunk and lower limb movements, grouped into functional movement patterns. Moreover, additional information on trunk and lower limb kinetics and muscle activity (using dynamic electromyography (EMG)) will highly contribute to the understanding of this functional relationship, and will provide more in-depth insights into compensatory mechanisms of the trunk versus the lower limbs and vice versa.

This is a multi-site research study with an optional research repository that will consist of clinically derived data and photographic or video images of patients in the home setting with complex health conditions to evaluate the safety and efficacy of the CHAMP® software platform, with data and photographic or video images input and/or uploaded by the parent or other legally authorized representative (LAR) of patients with complex congenital heart disease as a target population.

Currently, in order to visualize the inferior vena cava (IVC) of the heart using ultrasound, physicians traditionally place the ultrasound probe onto the "Subcostal" area which is located below the chest in the upper abdomen area. In this location, the pressure from the ultrasound probe is often uncomfortable for adults, and even more so for pediatric patients. Previous research and physician experience have demonstrated that it is possible to visualize the heart in the "transhepatic" area which is located under the arm on the side of the chest. By placing the ultrasound probe in this location, it is more comfortable for the patient when applying pressure, and this study aims to prove the effectiveness of visualizing the heart through this new location.

This feasibility and non-randomized comparison study explores the possible benefits of splint design and production by 3D-printing in a clinical setting and looks at splint users' experiences with customizable 3D-printed finger splints compared to conventionally made splints. Fifty participants with a hyperextended finger condition are assigned by researcher to either an interventional group (customizable 3D-printed finger splint) or a control group (conventional thermoplastic finger splint). Participants will wear assigned splint for 1 month. Functional status and satisfaction with splint will be assessed at the end of the 1-month duration in the form of surveys on satisfaction and functional status participants will be asked to complete. The findings will contribute to evidence that customizable 3D-printed finger splints can serve as a feasible, cost-effective option to improve patient satisfaction and functional status. It will further justify the need for the application of 3D-printing in a clinical setting.

This study follows an observational prospective cohort design. Women with fetal structural anomalies are routinely offered diagnostic testing with chorionic villus sampling or amniocentesis, with analysis for chromosomal analysis using karyotype or microarray analysis. Women in whom such testing does not explain the fetal phenotype, or in whom a genetic disease is strongly suggested based on the phenotype or a pattern of recurrent anomalies, will be offered exome sequencing (ES) and/or genome sequencing (GS) through the UCSF CLIA certified Genomic Medicine Laboratory. In advance of study enrollment, patients have been counseled regarding the structural anomalies in the fetus and offered pregnancy termination. The sequencing results for on-going pregnancies have a turnaround time of 2-4 weeks, and in the majority of cases are available after decisions have been made regarding continuation or termination of pregnancy. Patients who decline diagnostic testing but who have a prenatally identified anomaly may be offered the option of testing on umbilical cord blood at delivery or on the placenta or other products of conception after a stillbirth or pregnancy termination. The project is exploratory in nature, with the ultimate goal of contributing to a growing body of phenotypic data and understanding how providers and patients utilize genomic (either exome or genome) sequencing results during pregnancy.

Congenital malformations of the eye comprise various developmental defects including microphthalmia, anophthalmia, aniridia, and anterior segment anomalies (such as Peters and Axenfeld-Rieger anomalies). These malformations are frequently associated with extra-ocular features and intellectual disability. However, little is known about visual outcome, frequency and consequences of extra-ocular features in patients. The originality of the project will be to include a spectrum of malformation thought to be a phenotypic continuum (anophthalmia, microphthalmia, aniridia, anterior segment dysgnesis). In addition, we aim to conduct a 10 year follow-up of these children, thus allowing determining ocular and neurological outcomes as any other medical event. We should also be able to determine phenotypic factors that would be associated with good or poor visual and neurologic outcomes

Generation Victoria (GenV) is a longitudinal, population-based study of Victorian children and their parents that will bring together data on a wide range of conditions, exposures and outcomes. GenV blends study-collected, study-enhanced and linked data. It will be multi-purpose, supporting observational, interventional, health services and policy research within the same cohort. It is designed to address physical, mental and social issues experienced during childhood, as well as the antecedents of a wide range of diseases of ageing. It seeks to generate translatable evidence (prediction, prevention, treatments, services) to improve future wellbeing and reduce the future disease burden of children and adults. The GenV Cohort 2020s is open to all babies born over a two-year period, and their parents, residing in the state of Victoria Australia. The GenV Cohort 2020s is preceded by an Advance Cohort of babies born between 5 Dec 2020 and 3 October 2021, and their parents. This comprises all families recruited at GenV's Vanguard hospital (Joan Kirner Women's and Children's) and at birthing hospitals throughout Victoria as GenV scaled up to commence recruiting for the GenV Cohort 2020s. The Advance Cohort have ongoing and full participation in GenV for their lifetime unless they withdraw but may have less complete data and biosamples.
