Cause of Familial Testicular Cancer
https://clinicaltrials.gov/ct2/show/NCT00034424

May 7th, 2020 - BACKGROUND: Testicular germ cell tumors (TGCT) is the most common cancer in men aged 20-35, with an increasing incidence since the mid-twentieth century. A family history of TGCT is associated with an increased risk of the disease. Evidence suggests that there is genetic heterogeneity in familial TGCT, thereby creating opportunities for both new susceptibility gene discovery and searching for g...

Evaluation and Treatment of Skeletal Diseases
https://clinicaltrials.gov/ct2/show/NCT00024804

May 7th, 2020 - Human diseases are commonly manifested in the skeletal system. The skeleton may be the primary or secondary target of the disease and the disease may be congenital or acquired. While understanding of the molecular and cellular biology of bone and mineral disorders has increased in the last several years, much remains to be understood about the underlying biology of the skeleton. The gaps in the...

Stereotactic Body Radiation Therapy in Treating Patients With Metastatic or Recurrent Kidney Cancer
https://clinicaltrials.gov/ct2/show/NCT02542202

May 7th, 2020 - This pilot clinical trial studies the side effects and best dose of stereotactic body radiation therapy in treating patients with kidney cancer that has spread to other places in the body (metastatic) or has come back (recurrent). Stereotactic radiosurgery, also known as stereotactic body radiation therapy, is a specialized radiation therapy that delivers a single, high dose of radiation direct...

Evaluation of Patients With Mood and Anxiety Disorders and Healthy Volunteers
https://clinicaltrials.gov/ct2/show/NCT00024635

May 7th, 2020 - The purpose of this protocol is to allow for the careful screening of patients and healthy volunteers for participation in research protocols in the Experimental Therapeutics and Pathophysiology Lab (ETPB) at the National Institute of Mental Health (NIMH) and for the collection of natural history data. In addition the protocol will allow clinicians to gain more experience in the use of a variet...

Clinical and Genetic Analysis of Enlarged Vestibular Aqueducts
https://clinicaltrials.gov/ct2/show/NCT00023036

May 7th, 2020 - Nonsyndromic hereditary hearing impairment is a genetically heterogeneous disorder that can be caused by mutations in any one of at least 60 different genes. Enlargement of the vestibular aqueduct (EVA) is a radiologic finding known to be associated with mutations in one of these genes, the Pendred syndrome gene (SLC26A4, formerly known as PDS). EVA may thus serve as a clinically useful marker ...

Study of Transfusion-Transmitted Infections
https://clinicaltrials.gov/ct2/show/NCT00023023

May 7th, 2020 - Improved viral screening assays and more intensive questioning of donors for high-risk behaviors have resulted in dramatic declines in the rates of transfusion-transmitted hepatitis and AIDS. Nonetheless, there is need for continued vigilance of the safety of blood supply. This study will enroll blood donors and prospectively followed blood recipients in order to: 1) establish ongoing surveilla...

Advanced Heart Care at Home
https://clinicaltrials.gov/ct2/show/NCT03724695

May 7th, 2020 - End-of-life (EOL) care for heart failure (HF) patients includes high healthcare utilization and costs, in part due to the lack of integration of optimal HF management and home-based palliative care. In a pilot quality improvement project of clinician "nudges" to enroll seriously ill HF patients in a home-based, integrated HF and palliative care platform, the investigators demonstrated decreased...
