Health-related applications for smartphones represent a new and popular market for consumer oriented products. These applications are generally not considered medical devices and, as such, are not under the purview of the Federal Drug Administration. Some of these applications purport to measure vital signs, but do not have any published data to confirm accuracy of such measurements and their developers have not been willing to divulge the methods by which vital sign readings are produced. Use of unvalidated application derived data may contribute to patient harm as patients may make healthcare decisions based on the results these applications provide. This study aims to assess the accuracy of several such applications by comparing their findings to those of clinical vital sign monitors commonly used in the perioperative setting.
Many responders to the World Trade Center (WTC) disaster continue to experience significant mental and physical health problems. Two of the most common health problems, post-traumatic stress disorder (PTSD) symptoms and respiratory illness, often occur together. Mental health conditions, such as PTSD, make physical illnesses worse and interfere with treatment. The primary goal of this study is to test a mind-body treatment designed to reduce both PTSD and respiratory symptoms.
The aim of this study is to evaluate the effects of the use of breathing exercises with inspiratory loading on respiratory muscle strength and endurance, lung volumes and capacities and thoracoabdominal mobility in patients after bariatric surgery. It is believed that the use of inspiratory load may mitigate the negative effects of surgical trauma on respiratory muscle dysfunction, preserving respiratory muscle strength, lung volumes and diaphragm mobility, thus reducing the risk of pulmonary complications in the postoperative period.
This study investigated the acute effect of the consumption of four different kinds of coffee (hot and cold instant coffee, cold espresso and hot filter coffee) with the same caffeine content on salivary gastrin, cortisol and alpha-amylase concentrations, on self-reported gastrointestinal symptoms and on psychometric assessments in healthy individuals.
1. To study the early onset of symptomatic relief afforded by FLOMAX® capsules, 0.4 mg daily as compared to HYTRIN® capsules, 5 mg (with titration) daily in patients with the signs and symptoms of benign prostatic hyperplasia (BPH) 2. To evaluate patient's tolerability to the use of FLOMAX® capsules 0.4 mg daily in comparison to HYTRIN® capsules, 5 mg (with titration) daily for the treatment of the symptoms of benign prostatic hyperplasia
Study to evaluate the symptomatic relief afforded by tamsulosin hydrochloride capsules in patients with signs and symptoms of benign prostatic hyperplasia (BPH). Additionally to provide primary care physicians experience with the use of tamsulosin hydrochloride capsules 0.4 mg daily for the treatment of BPH
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.
