A panel discussion moderated by Dr. Thomas R. Cole, McGovern Chair in Medical Humanities and Director of the John P. McGovern Center for Humanities and Ethics at the University of Texas Health Science Center in Houston. Panelists include: Rabbi Samuel E. Karff, Rabbi Emeritus of Congregation Beth Israel and Associate Director of the John P. McGovern Center for Humanities and Ethics and Visiting Professor in the Department of Family Medicine at the University of Texas Health Science Center at the Texas Medical Center. Cardinal DiNardo, the second Archbishop of the Archdiocese of Galveston-Houston and the first cardinal archbishop from a diocese in the Southern United States. Dr. Sheldon Rubenfeld, Clinical Professor of Medicine at Baylor College of Medicine. He is Board Certified in Internal Medicine and in Endocrinology, Diabetes, and Metabolism, and is a Fellow in both the American College of Physicians and the American College of Endocrinology. Dr. Rubenfeld has taught "Healing by Killing: Medicine During the Third Reich" for three years and "Jewish Medical Ethics" for seven years at Baylor College of Medicine. He created a six-month program about Medicine and the Holocaust at Holocaust Museum Houston, including an exhibit entitled How Healing Becomes Killing: Eugenics, Euthanasia, Extermination and a series of lectures by distinguished speakers entitled "The Michael E. DeBakey Medical Ethics Lecture Series".

The purpose of this study was to determine if walking a dog would increase motivation to adhere to a walking program and result in an increase in walking endurance and mobility among institutionalized elderly. An experimental pre and post test two group randomly assigned study design was utilized. Thirty subjects, 20 females and 10 males with an average age of 72, were enrolled from three long-term care facilities. The walking program was 3 times a week for 6 weeks. The experimental group walked with a certified therapy dog and the handler. The control group walked with only the handler. The Outcome Expectations for Exercise Scale (OEES) was used to measure the perceived benefits of exercise. The 2-minute walk test and the 30 second chair stand test were administered before and after the walking program. The OEES scores did not significantly predict adherence to the program. The pre- and post-chair stand test and the 2-minute walk test did not show statistical significant differences between groups. All of the participants did show an increase (7 minutes) in walking time during the 6 week period (p=0.048). The mean pre and post walk test scores for participants with stroke/arthritis were significantly less than those without stroke/arthritis (p=0.013). The experimental group had 12 subjects with stroke/arthritis compared with 6 in the control group. The walk test means in feet walked were 362.44 ± 130.36 (control) vs. 201.27 ± 106.25 (experimental), p=0.001. The results indicate walking practice has the potential to increase walking time and endurance. Because residents of long-term care facilities were not allowed outside the facilities without accompaniment, the presence of the dog handler was key to their walking. Analysis of conversations during the walks indicated that for participants who walked with dogs, the dogs did serve as motivation for continuing in the program. ^

Development and implementation of a dynamic heterogeneous proton equivalent anthropomorphic thorax phantom for the assessment of scanned proton beam therapy By: James Leroy Neihart, B.S. Chair of Advisory Committee: David Followill, Ph.D Proton therapy has been gaining ground recently in radiation oncology. To date, the most successful utilization of proton therapy is in head and neck cases as well as prostate cases. These tumor locations do not suffer from the resulting difficulties of treatment delivery as a result of respiratory motion. Lung tumors require either breath hold or motion tracking, neither of which have been assessed with an end-to-end phantom for proton treatments. Currently, the RPC does not have a dynamic thoracic phantom for proton therapy procedure assessment. Additionally, such a phantom could be an excellent means of assessing quality assurance of the procedures of proton therapy centers wishing to participate in clinical trials. An eventual goal of this phantom is to have a means of evaluating and auditing institutions for the ability to start clinical trials utilizing proton therapy procedures for lung cancers. Therefore, the hypothesis of this study is that a dynamic anthropomorphic thoracic phantom can be created to evaluate end-to-end proton therapy treatment procedures for lung cancer to assure agreement between the measured and calculated dose within 5% / 5 mm with a reproducibility of 2%. Multiple materials were assessed for thoracic heterogeneity equivalency. The phantom was designed from the materials found to be in greatest agreement. The phantom was treated in an end-to-end treatment four times, which included simulation, treatment planning and treatment delivery. Each treatment plan was delivered three times to assess reproducibility. The dose measured within the phantom was compared to that of the treatment plan. The hypothesis was fully supported for three of the treatment plans, but failed the reproducibility requirement for the most aggressive treatment plan.
