Background: \- Multiple myeloma is a type of cancer that affects white blood cells and has a poor long-term survival rate. Two other types of cancer, monoclonal gammopathy of undetermined significance (MGUS) and smoldering myeloma (SMM), may eventually progress and develop into multiple myeloma. Researchers are interested in collecting samples from individuals who have been diagnosed with MGUS and SMM to study possible risk factors for developing multiple myeloma. Objectives: \- To study risk factors that may cause MGUS and SMM to progress to multiple myeloma. Eligibility: \- Individuals at least 18 years of age who have been diagnosed with either MGUS or SMM but do not have multiple myeloma. Design: * Participants will be examined by study researchers at the initial visit, at 6 months following enrollment, and every 12 months for a maximum of 5 years. * The following tests may be performed: (1) blood and urine tests, (2) bone marrow aspiration and biopsy, (3) imaging studies, and (4) a skeletal survey (a series of skeletal X-rays of the skull, spine, pelvis, ribs, shoulders, upper arm, and thigh bones). * Treatment will not be provided as part of this protocol. - Participants will remain on the study for 5 years, or until their MGUS or SMM progresses to multiple myeloma requiring treatment.
NCT04788082
Patient-specific, 3D printed models have been utilized in preoperative planning for many years. Among researchers and clinicians, there is a perception that preoperative exposure to 3D printed models, derived from patient images (CT or MRI), aid in procedural planning. 3D printed models for heart surgery have the potential to improve a clinician's preparedness and therefore may reduce surgically-related morbidity and mortality. This randomized clinical trial aims to evaluate whether pre-procedural planning of surgeons exposed to a patient-specific 3D printed heart model will decrease cardiopulmonary bypass time, morbidity, and mortality.
