NCT02911155
Background: The field of nuclear medicine has changed a lot in the past decades. Technology has gotten better, so patients are exposed to less radiation. But now workers are doing procedures more often and using lead aprons less. So they may be exposed to more radiation. This may put them at higher risk for cancers and other health problems that are related to radiation. Researchers want to collect data from technologists to learn more about the risks and appropriate doses of radiation. Objective: To learn more about the risks and appropriate doses of radiation for nuclear medicine technologists. Eligibility: Adults who were first certified in nuclear medicine technology in the United States after 1980. They must be living in the United States. They must not be participants in the USRT study. Design: Participants will be recruited online. Participants will complete an online survey. It will take about a half hour. This will have questions about their work with nuclear medicine procedures. There will be questions about the kinds of procedures and how often they do them. Participants will give a short work history. This will include the names of current and past employers. Participants will allow researchers to get records of their film badge dose readings. These will come from dosimetry providers. Dosimetry data will not be shared with participants. Researchers can t ensure the how accurate or complete the data are.
NCT00433381
This randomized phase II trial is studying the side effects and how well giving bevacizumab together with irinotecan or temozolomide works in treating patients with recurrent or refractory glioblastoma multiforme or gliosarcoma. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Drugs used in chemotherapy, such as irinotecan and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bevacizumab together with irinotecan or temozolomide may kill more tumor cells.
