Donor Stem Cell Transplant With Treosulfan, Fludarabine, and Total-Body Irradiation for the Treatment of Hematological Malignancies
NCT04195633
Recruiting
This phase II trial studies how well a donor stem cell transplant, treosulfan, fludarabine, and total-body irradiation work in treating patients with blood cancers (hematological malignancies). Giving chemotherapy and total-body irradiation before a donor stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy ste... Read More

Collecting and Studying Blood and Tissue Samples From Patients With Locally Recurrent or Metastatic Prostate or Bladder/Urothelial Cancer
NCT01050504
Recruiting
This study collects and studies tissue and blood samples from patients with prostate or bladder/urothelial cancer that has recurred (come back) at or near the same place as the original (primary) tumor or has spread to other parts of the body. Studying samples of blood and tissue samples from patients with prostate or bladder/urothelial cancer in the laboratory may help doctors learn more about new biomarkers, potential drug targets, and resistance developing in response to treatment. It may als... Read More

A Multi-Modal Combination Intervention to Promote Cognitive Function in Older Intensive Care Unit Survivors
NCT06411561
Recruiting
Up to 25% of intensive care unit (ICU) survivors experience cognitive impairment comparable in severity to mild Alzheimer's disease and related dementias after hospital discharge. Older ICU survivors (ages 60 and older) are at highest risk for delirium and subsequent cognitive impairment, which contribute to higher risk for cognitive decline related to Alzheimer's disease and related dementias. Sleep and activity are essential for recovery from critical illness, yet ICU survivors experience both... Read More

Evaluation of A Clinical Diagnostic Test for CRDS
NCT06188689
Recruiting
Calcium Release Deficiency Syndrome (CRDS) is a novel inherited arrhythmia syndrome secondary to RyR2 loss-of-function that confers a risk of sudden cardiac death. Diagnosis of CRDS presently requires cellular-based in vitro confirmation that an RyR2 variant causes loss-of-function. We hypothesize that CRDS can be diagnosed clinically through evaluation of the repolarization response to brief tachycardia, mediated by cardiac pacing, and a subsequent pause.
