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.
A prospective evaluation of postoperative corneal aberrations and visual parameters in patients assigned to either an AcrySof IQ Toric intraocular lens (IOL) group or a group implanted with a SN60WF IOL and having concomitant limbal relaxing incision.
With the aging of the population, the prevalence of age-related macular degeneration (AMD) eye disease has resulted in a large number of people suffering from central vision loss. In fact, the most prevalent cause of blindness among veterans is AMD. Since the number of elderly veterans is expected to double in the next 10 years, loss of vision due to AMD is also expected to proportionally and considerably escalate. People with impaired vision have difficulty with daily activities, such as, reading, driving, and recognizing faces. The goal of the research project is to provide information on factors that contribute to visual impairment. This knowledge is necessary for the development of innovative approaches that will optimize the benefit of vision rehabilitation techniques, aimed at improving vision, thus allowing our veterans to maintain function and productivity. The findings from the proposed research will benefit our veterans and all aging people.
To measure and compare pain associated with venipuncture and peripheral intravenous catheter insertion among pediatric emergency department patients randomized to treatment with one of three different pain-reduction strategies: J-Tip® jet injection of 1% buffered lidocaine, J-Tip® jet injection of sterile saline, or application of 4% lidocaine topical cream. The investigators hypothesize that J-Tip® jet injection of 1% buffered lidocaine will provide superior local anesthesia compared to saline or lidocaine cream.
Background: - AVN944 is an experimental cancer treatment drug, not yet approved by the U.S. Food and Drug Administration. To date, AVN944 as a single drug has been tested in several studies involving humans, including healthy volunteers, patients with leukemia, and patients with advanced pancreatic cancer. - More research is needed to determine the safety and effectiveness of AVN944. Objectives: - To determine the safety of AVN944. - To determine the maximum tolerated dose (the highest dose that does not cause unacceptable side effects) of AVN944. - To see if AVN944 has any effect on patients' tumors. - To learn how the body breaks down AVN944. Eligibility: - Patients 18 years of age and older who have advanced stage solid tumors for which standard therapies do not exist or are no longer effective. Design: - Participants will have a screening visit and five clinic visits during the first treatment cycle. Additional treatment cycles will involve two clinic visits during each 28-day cycle. After participation in the study ends, patients will be asked to return within 28 days after the last dose of study drug for final study procedures. - Evaluations before the treatment period: - Physical examination, including vital signs and body weight checks, and pregnancy test for women who can become pregnant. - Questions about medications and side effects. - Blood and urine tests. - Disease evaluation with CT, chest x-ray, and additional laboratory tests depending on the type of cancer. - All patients will have blood samples taken at each visit. - Patients will take specific doses of AVN994 as directed by researchers, and will be asked to keep a diary to record their doses and any side effects. They will be monitored with frequent blood draws at each study visit to provide information on the safety and effectiveness of the drug. - During different cycles, patients will have their disease evaluated by researchers and will be asked if they wish to continue taking AVN994 as part of the study.
This research study is being done in order to find out if there is any difference in the effectiveness of ultrasound guided supraclavicular brachial plexus nerve block that can be achieved with 3 different amounts of ropivacaine 0.5% (20 ml, 30 ml, and 40 ml). The investigators want to show if you can have a successful nerve block with less amount of local anesthetic, thus potentially decreasing the risk of side effects.
Our objective is to evaluate the clinical outcomes for the anatomic radical perineal prostatectomy (RPP) for the surgical management of prostate cancer. We will report the perioperative, oncologic, and functional outcomes in patients undergoing the radical perineal prostatectomy at our institution.
Short bowel syndrome (SBS) is a form of disease that results from removal of a significant portion of the intestine leading to poor nutrient absorption. Infants with short bowel syndrome suffer from diarrhea and poor growth. The care of these infants is limited by the lack of effective therapies. Soluble fiber (guar gum) is an indigestible form of sugar that is mostly contained in fruits and vegetables. Soluble fiber can reduce the severity and duration of persistent (constant) diarrhea in children. The purpose of this research study is to evaluate the many effects of fiber added in the diet of infants with SBS
The purpose of this research study is to more accurately measure the amount of true red blood cell breakdown (hemolysis) in newborn babies with potentially problematic blood type mismatch with their mothers (ABO incompatibility), and to examine how the true level of red blood cell destruction relates to other laboratory tests obtained in newborns with jaundice. A better understanding of the true amount of red blood cell destruction that is caused by blood type mismatch, as well as how it relates with other laboratory tests ordered for ABO incompatibility and red blood cell destruction, would help avoid unnecessary testing, treatment and prolonged hospital stays in such babies.
The purpose of this research study is to see if adding enoxaparin sodium to standard treatment with the chemotherapy drugs cisplatin and etoposide will help treat extensive stage SCLC. Two different doses of enoxaparin sodium will be studied in order to determine if one dose is more effective than the other. Enoxaparin sodium (Lovenox) is a drug that is approved by the FDA to help treat or prevent blood clots. Results from previous research studies suggest that adding enoxaparin sodium to standard treatment improved the response to treatment for some study participants with various types of cancer.
The purpose of this study is to measure the effects of allergens and/or diesel exhaust particles in the nose to learn more about allergic responses in individuals with cat allergic rhinitis.
