There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The investigators would like to investigate the efficacy of more frequent treatment with Lucentis for subjects with persistent diabetic macular edema despite standard dosing regimen.
The purpose of the study is to determine if endoscopist notification of accessory cost results in altered resource utilization related to the total cost and number of accessories used in ERCP. This study will be a prospective cost--analysis study. Only chart review of PHI removed records will be used. The only intervention used is that endoscopists will be made aware of the cost of accessories used in the second phase of the study following each ERCP. The investigators are in an era of increased medical cost consciousness. Medical education and post--graduate education incorporates cost savings and appropriate diagnostic test selection based on expense as one aspects of the decision process. This era now focuses on what is best for the patient with the understanding that the cost to the patient and cost to the overall health care system matters. Not only is this apart of postgraduate training but now being implemented as part of Medicare reimbursement to provide low cost and high quality care. Incidence of pancreatic and biliary disease is increasing. ERCP is a vital tool for therapeutic intervention. The costs of these procedures, to both patients and hospitals, have caused some to question the amount of accessories used as well as the poor reimbursement provided by Medicare and insurers. Studies have indicated that hospitals actually lose money with each ERCP used and their use is being limited many times to tertiary care centers.
This phase I clinical trial studies the side effects and best dose of auranofin and sirolimus when given together in treating patients with non-small cell lung cancer. Immunosuppressive therapy, such as auranofin and sirolimus, may be an effective treatment for non-small cell lung cancer. Sirolimus may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving auranofin and sirolimus may be an effective treatment for non-small cell lung cancer.
The Boston Keratoprosthesis type I (KPro) is a prosthetic cornea used to treat several causes of corneal blindness. Some categories of patients, including those with auto-immune diseases such as Stevens-Johnson syndrome, toxic epidermal necrolysis syndrome and mucous membrane pemphigoid, have a higher risk of failure for the KPro. Because of chronic inflammation, the cornea supporting the KPro may melt, leading to a higher risk of infection, loss of the KPro and loss of the eye. Infliximab is an antibody against tumor necrosis factor alpha and is used intravenously to control inflammation in several diseases. It has been used in some cases of corneal melting with significant success. This study's hypothesis is that infliximab can be successfully used as an eye drop (instead of the usual administration through veins) and that its regular use may prevent melt in eyes with a Boston Keratoprosthesis type I and underlying auto-immune disease.
The purpose of this study is to evaluate improvement in balance after receiving physical therapy when augmented by CN-NINM than when augmented by a placebo (sham CN-NINM).
This will be a 4-way comparison to prospectively evaluate the efficacy and patient tolerability of four commercially available bowel preparations among patients undergoing colonoscopy for screening and surveillance in a single tertiary academic medical center.
The purpose of this study is to investigate the relationship between ear fullness, pressure, and/or pain and laryngopharyngeal reflux, in order to focus medical therapy and improve therapeutic outcomes in this patient population.
The study aims to evaluate the effect of non-supine positioning in the treatment of surgical patients with obstructive sleep apnea. The hypothesis is that non-supine positioning will result in a decrease in acute hypoxic events, defined as the number of apneas/hypopneas per hour of sleep.
Sjögren's syndrome (SjS) is an autoimmune disease characterized primarily by exocrine gland dysfunction, specifically of the salivary and lacrimal glands, resulting in dry mouth and dry eyes symptoms. It can be systemic by affecting other organs including the gastrointestinal tract, skin, lungs, vasculature, kidneys, bladder and vagina. Involvement of the musculature can lead to fibromyalgia-like symptoms and chronic fatigue, while approximately 20% of patients develop various neuropathies, including sensory, peripheral, cranial and myelopathic neuropathies exhibited by cognitive impairments such as dementia, lack of concentration, memory loss and various psychiatric disorders. Like most autoimmune connective tissue diseases, SjS shows a sexual dimorphism with women affected 10-times more frequently than men, suggesting a role for sex hormones in disease susceptibility or progression. One common feature of SjS is it infiltration of mononuclear cells into the salivary and lacrimal glands, aggregating into clusters referred to as lymphocytic foci (LF). Critical to the studies proposed is the fact that a predominant cell population of LF is the pathogenic TH17 cell that produces IL-17 cytokine and autoreactive B cells reactive to M3R, Ro, and La autoantigens. The goal of this study is characterize the change in receptor gene repertoires of autoreactive B and T cells at different time points during the disease process and examine the correlation with various disease parameters.
The purpose of this study is to understand the differences in how patients with heart failure respond to exercise training compared to patients with heart failure and type 2 diabetes.
