NCT04728867
Digital 3D animation and cadaveric videos have been increasingly used in surgical education and provide tremendous opportunity to develop new surgical educational tools, particularly during this Coronavirus-19 pandemic period. This prospective, randomized, blinded study is designed to compare the educational effectiveness of various educational tools including the surgical textbook, animation, and cadaveric videos in laparoscopic rectal surgery among board-certificated surgeons. Initially, an electronic questionnaire assessing the knowledge about laparoscopic rectal surgery will be created and validated by the board-certificated colorectal surgeons. Exploratory and confirmatory factor analyses will be utilized to test the structure validity of the questionnaire. After the questionnaire will be sent to the graduates completing the general surgery residency program in Turkey, the volunteers will be then randomized into four groups based on the study material including a textbook, 3D animation, cadaveric video, and both 3D animation + cadaveric video. A step-by-step educational 3D animation and a cadaveric video will be prepared in order to teach the technical steps of laparoscopic rectal surgery. Volunteers in four groups were given 2 weeks to review their educational material. After the 2-weeks of the study period, the volunteers will be asked to answers the same electronic questionnaire imported in the edited live laparoscopic rectal surgery. Pre- and post-educational assessment of the questionnaire among the groups will be performed and compared.
NCT00592865
Study Objective: Brain tumors are poorly understood. The purpose of this research is to examine whether factors in lifestyle play a role in brain tumor development. The study will also investigate the contribution of inherited susceptibility to the risk of brain cancer. By gaining a better understanding of these influences, the investigators hope to learn how to prevent brain tumors in future generations, and to develop more effective strategies for treatment. Study Protocol: This is a case-control investigation. Persons affected with a brain tumor are compared to unaffected persons on previous medical history, diet and other factors. Those enrolled in the study will participate in an interview on general background, diet, medical history and lifestyle, and will provide a sample of DNA, clippings of your toenails, and a tap water sample from your home. All procedures are performed in the clinic or through the mail. 'Cases': Cases eligible for the study are persons with a recent diagnosis of a primary brain tumor (glioma or meningioma), at least 18 years of age. 'Controls': Controls in the study are non-family members of patients, similar in age and of the same gender. Suitable controls include in-laws, friends, neighbors and co-workers.
