Filter by:Background: - Alzheimer s disease affects the brain and causes memory and thinking problems in older people. Macular degeneration (MD) is an eye condition. It is the leading reason that people over age 55 in the United States lose their central vision. Central vision is important for seeing fine details and for tasks like reading and driving. A feature of Alzheimer s disease is plaques in the brain. A feature of age-related MD is deposits in the retina in the eye. Researchers want to learn more about these diseases and find out if they are related. Objective: - To see whether there is a relationship between Alzheimer s disease and age-related macular degeneration. Eligibility: - People with or without Alzheimer s disease enrolled in another study. Participants must have someone to help them take part in this study. Design: - Participants will be screened through the other study. They will have 1 visit. The tests will take about 3 hours. - Participants will answer questions about their medical and eye history. - Participants will have an eye exam to test how well they see. Their eye pressure will be measured and their eye movements will be checked. - Participants will get eye drops to dilate their pupils. Researchers will take pictures of the retina and the inside of the eye. Researchers may measure the thickness of the retina. - Participants will continue to receive care from their regular eye doctor during and after the study.
A multi-center, double-blind, randomized, placebo controlled, parallel-group study, comparing Clindamycin phosphate vaginal cream 2% (Watson Laboratories, Inc.) to Clindesse® (Ther-Rx™, Clindamyin Phosphate Vaginal Cream 2%) and both active treatments to a placebo control in the treatment of bacterial vaginosis in non-pregnant women.
To evaluate if nutritional treatment with nutritional supplementation of dietary fiber reduces cholesterol levels and triglycerides (dyslipidemia) in patients with HIV/AIDS receiving antiretroviral therapy (HAART).
Purpose: This study will evaluate a new ultrasound imaging technology called acoustic angiography. Acoustic angiography uses an ultrasound contrast agent, already FDA approved for use in cardiology, to enhance imaging of blood vessels. Since acoustic angiography uses ultrasound, and not x-rays, the patient is not exposed to ionizing radiation, unlike traditional angiography and mammography. Specific goals will be to evaluate the quality of the images provided by acoustic angiography in the human breast, and furthermore to evaluate whether or not acoustic angiography provides additional diagnostic information over traditional ultrasound which could provide an improvement in assessing breast lesions. Specifically, this additional diagnostic information will hopefully enable us to reduce false positive tests and discriminate lethal cancers from non-lethal disease. Participants: The investigators are recruiting 60 patients from the UNC Breast Clinic who are undergoing core needle biopsy or surgical biopsy (BIRADS 4 and 5 breast lesions). Procedures (methods): Acoustic Angiography imaging will be performed in conjunction with standard diagnostic imaging, including b-mode ultrasound . Then, a reader study will be conducted to compare these modalities. Finally, the images will be analyzed with image processing techniques to determine quantitative metrics exhibited by the blood vessel morphology in the images. These metrics will be utilized to develop a "malignancy score" equation to predict malignancy of a lesion.
This study is a randomized, double-blind, placebo-controlled, crossover design study in healthy subjects to determine the effects of a polyherbal supplement on the signs and symptoms of delayed onset muscle soreness (DOMS) induced by eccentric exercise of the arm.
Orthostatic hypotension following total hip arthroplasty is known to limit the ability of patients to perform physical therapy (PT) and increase the length of hospital stay and costs. Our goal is to prospectively study the effects of oral midodrine on the signs and symptoms of orthostatic hypotension in 20 patients and the effects of intravenous fluid on the signs of symptoms of orthostatic hypotension in 10 patients. Midodrine will be administered to patients with suspected low SVV, and an intravenous fluid bolus will be administered to patients with low CO. 120 patients will be consented with a view to studying 30 patients who meet the inclusion criteria for orthostatic hypotension. Patients who receive midodrine or the fluid bolus will undergo hemodynamic measurements at 30 min, 1 hr, 2 hrs, 3 hrs, and 4 hrs post-intervention. All patients will undergo measurements for blood pressure, arterial augmentation index, and heart rate at baseline (pre-op; holding area) and the time of first PT attempt. Patients will be monitored up to post-operative day 3. The working hypothesis is that midodrine or fluid therapy will significantly raise the mean arterial blood pressure (MAP) by 5 mmHg+ and/or cause a significant change in the Orthostatic Hypotension Questionnaire (characterized by a two-point improvement in symptom score).
To evaluate the therapeutic equivalence of the lest formulation of Mometasone Furoate Nasal Spray, 50 mcg to the marketed formulation NASONEX® (mometasone furoate monohydrate) Nasal Spray, 50 mcg/actuation in patients with seasonal allergic rhinitis
The study will compare the safety and efficacy of a generic mometasone nasal spray to the reference listed drugs in the treatment of seasonal allergic rhinitis. Additionally both the test and the reference formulations will be tested for superiority against a placebo nasal spray.
Purpose: The proposed research, if successfully implemented, will result in a low-dose, low-cost, and highly effective method for screening of lung cancer, leading to reduction of the lung cancer mortality rate. Using the stationary Digital Chest Tomosynthesis (s-DCT) system the imaging dose for a full tomosynthesis scan is expected to be only 10% of that from a low-dose computed tomography (CT). The targeted imaging time of 2s is 1/5 to 1/3 of that from a current commercial digital chest tomosynthesis (DCT) system at the same imaging dose. Beyond lung cancer screening, the low-dose and sensitive 3D lung imaging modality will likely to find applications in areas such as monitoring of pediatric cystic fibrosis patients where reduction of imaging dose is critical. Participants: One hundred (100) patients undergoing a clinical non-contrast CT for their lung nodules will be asked to have this procedure (scan) within 2 weeks (+/- 1 week) of their clinical CT and chest radiograph, with no intervening procedures or therapies. Procedures (methods): The purpose and endpoint of this study is to compare the sensitivity of the s-DCT system to the conventional chest radiographs with non-contrast chest CT as the reference standard. One hundred (100) patients undergoing a clinical non-contrast CT for their lung nodules will be asked to have this procedure (scan) within 2 weeks (+/- 1 week) of their clinical CT and chest radiograph, with no intervening procedures or therapies.
The purpose of this study is to describe most characteristic association of signs and symptoms present at the time of acromegaly diagnosis.
