Active clinical trials for "Congenital Abnormalities"

To assess safety and efficacy of ONYX treatment for cAVM:

The study is an extension of earlier work based on a retrospective epidemiologic study of infants born to women who were exposed to bupropion in their estimated first trimester of pregnancy using data from a large US health plan affiliated with i3 Drug Safety (Clinical study ID WWE113694) (Cole JA, Oh KS, Chiang CC, Walker AM, Haight BR, Modell JG. Bupropion in pregnancy and the prevalence of congenital malformations Pharmacoepidemiology and Drug Safety, 2007; 16: 474-484). The cohorts developed for the earlier work consisted of all infants born to women exposed to bupropion during the estimated first trimester and outside the first trimester, and a random sample of infants born to women exposed to other antidepressants during the first trimester between 01 January 1995 and 30 September 2004. The objectives for this study include refining of both the original first trimester bupropion cohort and the original bupropion outside the first trimester cohort into mono-therapy and mono- or poly-therapy. Exposure to other antidepressants during the first trimester will also be refined into mono-therapy and mono- or poly-therapy. With input from pediatric cardiology expert, lists of specific cardiovascular malformations and malformation groupings will be created. The groupings will be created among the refined first trimester bupropion cohort as well as in two comparison cohorts of bupropion outside the first trimester and first trimester antidepressant use (mono-therapy and mono-or poly-therapy). The prevalence in each cohort will be calculated as the number of infants with a specific cardiovascular malformation divided by the number of live born infants. Prevalence will be reported per 1,000 infants. Confidence intervals will be calculated using Wilson's approximation to exact binomial intervals when the number of cases is five or greater and exact binomial intervals when the number of cases is fewer than five. The appropriateness of further calculations will be evaluated. Where numbers permit, adjusted odds ratios for specific cardiovascular groups/malformations will be calculated and if appropriate, stratified according to maternal dispensing of medications suspected to be teratogenic. The following comparisons, if numbers permit, will be performed: 1) bupropion first trimester mono-therapy cohort versus other antidepressant first trimester mono-therapy cohort; 2) bupropion first trimester mono- or poly-therapy cohort versus other antidepressant first trimester mono- or poly-therapy cohort; 3) bupropion first trimester mono-therapy cohort versus bupropion outside of first trimester mono-therapy cohort, and 4) bupropion first trimester mono- or poly-therapy cohort versus bupropion outside of first trimester mono- or poly-therapy cohort. Adjusted odds ratios will be calculated through a generalized estimated equations form of multivariate logistic regression to account for births associated with multiple infants. The same covariates identified in the original study will be included in this re-analysis. Covariates included: diagnoses of bipolar disorder and eclampsia within one year before delivery; dispensings of lithium, phenytoin, and fluconazole within one year before delivery through the end of the first trimester; and the number of physician visits within 10 to 12 months before delivery, maternal age, geographic region of the health plan, and infant gender. If generalized estimating equation form of the logistic regression model does not converge, adjusted odds ratios will be presented from a conventional multivariate logistic model. If the conventional multivariate logistic model does not converge, only the crude odds ratio will be presented.

The Spine TRACK Spinal Surgery Registry is a prospective multi-center observational data collection initiative, to capture clinical and radiographic outcomes in candidates for spine surgery with degenerative, deformity, and traumatic pathologies. As an observational database, there are no initial driving hypotheses, but rather data will be mined to answer unforeseen questions, but which may include broad topics such as comparative effectiveness between and among various surgical treatment options, and/or outcomes in various subgroups of patients such as defined by demographics, comorbidities, indications and symptoms, treatment variables, and/or outcome variables.

Controversy exists in the treatment of airway hemangiomas ranging from tracheotomy, various lasers, to open removal, none of which have proven to be a gold standard. Venous malformations of the airway are difficult to treat and also require laser therapy or open removal and often repeated treatments are required. Similarly airway lymphatic malformations can require multiple treatment modalities as well as multiple procedures and are infrequently eradicated when extensive. New uses for various lasers and differing treatment protocols are frequently developed. Review of the treatment modalities and efficacy of these methods is required. The goal of this research is to determine protocols for treatment of airway vascular malformation and to evaluate our results from treatment of these lesions.

The purpose of the study is to evaluate implant stability and stimulate clinically relevant horizontal and vertical new bone formation around Nobel Biocare's Bone Inductive Implant.

To create a registry of all Oregon children undergoing surgical repair of congenital heart disease since 1958 in order to determine mortality, morbidity, and disability after surgery and to assess the safety of pregnancy in women with corrected congenital heart disease and the risk of prematurity and occurrence of congenital heart defects in offspring.

The International Cohort Study of Children Born to Women Infected with Zika Virus (ZIKV) During Pregnancy study is a prospective, observational, international cohort study of children previously enrolled in the ZIP study or other ZIP 2.0 Protocol Team approved ZIKV-cohort study that will continue the longitudinal follow-up of children born with documented confirmed or presumptive in-utero ZIKV exposure ("ZIKV-exposed" cohort) and children born without documented confirmed or presumptive in-utero ZIKV exposure, matched by site and birth sex ("ZIKV-unexposed" cohort). Follow-up evaluations and assessments will allow for the determination and comparison of long-term neurodevelopmental outcomes among in utero ZIKV-exposed and ZIKV-unexposed children. Each participant will be followed for about 2 years, beginning at approximately 18 months through 42 months of age.

The SALMANTICOR study will obtain data on the prevalence and incidence of structural heart disease in a population setting. A cross-section survey of randomly selected residents of Salamanca (Spain) will be performed. A total of approximately 2400 individuals, stratifies by place of residence (rural and urban) and by age and sex will be studied. The variables to analyzed will be obtained from the clinical history, different surveys including social status, Mediterranean diet, functional capacity, electrocardiogram, echocardiogram and biochemical and genetic analysis. Surviving participants are expected to return for a 5 and 10-year follow-up visit.

The purpose of this study is to translate and culturally adapt the quality of life profile for spinal deformities (QLPSD) to Turkish language and test the validity and reliability of Turkish version of QLPSD in patients with adolescent idiopathic scoliosis.

Orthofix is conducting this retrospective Post-market clinical follow up (PMCF) study to assess the safety and clinical performance of the GGPSP device, which is a new version of the Guided Growth Plate System (GGPS) from which it differs for small modifications compared to the original design. The purpose of the study is to collect clinical evidence from the use of the device in a representative number of pediatric patients who have already been treated with the device in the study and with at least one control visit post removal of plaque.. For this purpose, a retrospective PMCF study was considered to be the most appropriate study design to obtain the necessary information.
