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.
Many chemotherapy combinations may be used to treat patients with chronic lymphocytic leukemia (CLL). Although there are many options, a single, best option is not agreed upon by most cancer specialists. Bendamustine, a medicine recently approved for use in the United States, has been used in combination with rituximab in previous studies to treat patients whose CLL has returned after previous standard treatments. The purpose of this study is to determine whether bendamustine with rituximab is effective for the initial treatment of CLL for patients aged 65 and older.
The purpose of this study is to compare the effects of apomorphine, given by two different methods, to determine how best to manage dyskinesias.
Generally, patients who have undergone treatments for Head Neck Cancer have a decreased quality of life and experience depression and fatigue. Regular physical activity improves emotional well-being, increases immunological response, improves wound healing, lessens fatigue and improves general functionality and quality of life. This study will determine effectiveness of the 12-week exercise intervention program, determine if physically active patients differ in quality of life, depression and fatigue during the course of the study, and determine if the change in physical activity levels is related to changes in immune responses.
The purpose of this prospective clinical data-collection is to document the performance and clinical outcomes of the Microplasty Tibial Tray.
The Study Investigators have seen high rates of tobacco cessation success combining Chantix with the risk of no surgery, should tobacco use continue. Once patients achieve tobacco cessation and undergo surgery, the investigators have seen high rates of union and/or infection resolution. The investigators are looking to document and publish these observations. To date, no studies have been published that have examined the effects of this type of protocol on short and long-term tobacco cessation. The investigators want to examine and report the outcome of Hershey Medical Center's Orthopaedic Trauma Division's protocol for two endpoints: 1) pre-op tobacco cessation and 2) duration of tobacco cessation. This protocol involves counseling, Chantix, and a 'no-surgery' risk. Patients will be followed postoperatively for success and duration of tobacco cessation, as well as for fracture union and/or infection eradication.
This study will assess the effect of IT-101 on delaying cancer progression in patients with platinum sensitive ovarian cancer.
This study seeks to determine whether the Lactic Acid blood level in a critically ill patient must be drawn with a non-tourniquet venipuncture. The null hypothesis is that there is no significant difference in Lactic Acid blood level in critically ill patients in a sample taken from either with a tourniquet or a non-tourniquet veni-puncture. Monitoring of Lactic acid level is helpful in both identifying potentially serious ill patients as well as identifying in the ICU patients with high morbidity and mortality. When a patient arrives to an Emergency Department and that patient is hypotensive (BP less than or equal to 90 systolic), the nursing staff often starts an IV and if possible draws the patient's initial blood tests off that first IV site; or if the patient has had an IV started in the field by EMS, the nursing staff will draw blood from another site using a tourniquet. This initial work up by the nursing staff takes 15 -20 minutes before a physician may see the patient. Since the present standard Lactic Acid test must be drawn either by arterial puncture or venipuncture without a tourniquet, this test is rarely done as part of their (the RNs) initial blood draws. This simple impediment of needing to repeat the venipuncture without a tourniquet, especially in patients who often have venous access difficulty, delays the identification of appropriate patients for early and aggressive management- particularly those with sepsis. Our hypothesis is that this requirement for a non-tourniquet blood draw is unnecessary.
This study seeks to determine in Neonatal Intensive Care Unit (NICU) patients specific improvements in pulmonary function which may occur when an infant is ventilated in the prone as compared to the supine position. Modest improvement in oxygen has been reported to occur with prone positioning, but the exact etiology for this change is not clear. A special incubator designed as an integrated care system allows routine care and the measurement of both patient and ventilator breaths during mechanical ventilation. This study will utilize this device to evaluate in NICU ventilated patients whether specific changes in pulmonary function accompany position changes, and whether these are correlated to a change in pulmonary gas exchange.
The purpose of this study is to evaluate patients with cirrhosis of the liver and renal failure and determine if the administration of rifaximin as compared to lactulose is associated with less frequent and/or slower progression to severe hepatic encephalopathy. If one is associated with lower blood ammonia levels. And, if one is associated with lower breath hydrogen and methane levels.
The investigators plan to enroll 500 consecutive Subjects at a major trauma center for this study. For each patient, the body mass index (BMI), age, sex, diastolic pressure and mean arterial pressure (MAP) at time of measurements. Additional information including diseases such as diabetes and vascular disorders will be recorded. Social demographics including alcohol and tobacco use will be recorded. This is important as alcohol and tobacco use could also contribute to cardiovascular diseases. The skin pigmentation of each subject will be recorded. Two different methods will be used for this measurement. Each patient will be graded on a six point scale as described by Young (Young, 1997). Additionally, each subject will have their skin measured using a reflectance colorimeter. The colorimeter, DermaSpectrometer II (cyberDerm, Broomall, PA) uses visible light to measure the amount of light reflected off the skin. By measuring the light reflectance, the skin pigmentation can be measure (Clarys, 2000). Muscle oxygenation will be measured using a continuous dual wavelength near infrared spectrometer. Using the different absorption characteristics of deoxyhemoglobin and oxyhemoglobin, the concentration of oxyhemoglobin in the muscle at an approximate depth of 2.5 cm is determined. The INVOS cerebral oximeter (Somanetics, Troy, MI) will be used for all measurements.
