Its use is associated with improved myelotoxicity and increased risks of thromboembolism and second primary cancers. Together with the findings reported by McCarthy et al.,19 our data support the use of lenalidomide maintenance therapy after high-dosage chemotherapy and autologous hematopoietic stem-cell transplantation in patients with myeloma, but the impressive benefits should be weighed against the elevated risks..

Results: Individuals randomized to the iPhone program group have scored higher on the observed performance of the PRM compared to the placebo group with a mean difference of 4.98 points. Participants randomized to the placebo group regularly performed the maneuver quicker than those that had an operating iPhone application. The common placebo participant performed the maneuver in only 79.9 seconds while participants in the test group averaged 245.8 secs. In summary, preliminary testing demonstrated that individuals using the DizzyFix iPhone program conducted the PRM more accurately and slowly compared to the participants using a placebo.
