NCT00481754
Background: * Endometrial cancer (cancer of the lining of the uterus) is the most common gynecologic cancer in the United States. * Currently, there are no markers (components of blood and tissue that determine who might be at risk for developing cancer) for endometrial cancer. Objectives: -To see if women who are undergoing hysterectomy are willing to provide blood and tissue samples to help doctors identify markers that would indicate increased risk for developing endometrial cancer. Eligibility: -Women between 35 and 54 years of age who will undergo hysterectomy for a non-cancerous condition, such as uterine fibroids, uterine prolapse, abnormal uterine bleeding, and others at Magee-Women's Hospital in Pittsburgh, Penn. Design: * Patients' medical records are reviewed and patients complete a questionnaire including information on race and ethnic background, education, marital status, family history, height, weight, pregnancy history, smoking history, medication history, history about menstrual periods and menopausal symptoms. * Patients provide blood and urine samples before surgery. * A sample of fat tissue is removed during surgery in patients undergoing abdominal surgery. * Tissue samples from the removed uterus (and ovaries if the ovaries are also removed) are collected and analyzed for markers for endometrial cancer.
NCT03850197
The Eustachian tube (ET) is a biological tube that links the middle ear to the back of the nose and throat. It has several functions, of which the most important is to maintain optimal middle-ear health. Eustachian tube dysfunction (ETD) can result in pain or a popping sensation in the ears when flying in an airplane or going up a tall building in an elevator. Many people with ETD also suffer from ear problems such as repeated middle-ear infections or fluid in the ears. However, there are very few easily-administered tests to measure and assess Eustachian tube function (ETF). Tubomanometry is one of these tests, however it is expensive and used to measure ETF only in research settings. In this study, the investigators propose that using a combination of two readily available devices, the EarPopper and a tympanometer, will work in a manner similar to a Tubomanometer to test ET function.
