The InfantPod study is a cross-sectional study designed to determine how practical and precise a body composition method is for measuring body fat and lean tissue in infants and children ages 5 months to 3 years.
Contrast induced nephropathy (CIN) is a term applied to acute renal failure associated with intravascular injection of iodinated contrast agents typically used for cardiac angiography. CIN occurs in about 15% of those who have had cardiac angiography, with dialysis required by about 0.5% of cases. The development of CIN is associated with other adverse outcomes including major adverse cardiovascular events (MACE) and death. The mechanism underlying the association with MACE and death is unclear and it is largely unknown whether measures reducing the frequency or severity of CIN also reduce these associated adverse events. The cause of CIN in humans is not known, but many preventive therapies have been tested based on our understanding of the mechanism underlying CIN from animal models. Despite multiple studies, no one drug or therapy has been proven to consistently prevent CIN at this time. Prophylactic fluid therapy is uniformly recommended as a component of preventive approaches for CIN. However, the optimal type, dose and duration of fluid therapy remain unclear. Existing studies suggest a role for isotonic saline[3] or bicarbonate[4]. Initial use of hypotonic fluid followed by isotonic fluid might allow a more rapid and sustained increase in tubular fluid flow by suppression of ADH. This should assist in reducing tubular fluid viscosity and the potential for injury by contrast medium. The aim of this research program is to design and test strategies for the prevention of CIN in patients undergoing elective cardiac angiography or percutaneous coronary intervention (PCI). The primary purpose of this pilot study will be to determine the biological plausibility of using a hypotonic solution for CIN prophylaxis. Specific Objectives: Primary 1. To compare the effects of two fluid prophylaxis strategies for CIN on urine output, urine pH, urine composition (urine metabolic profiling), a novel marker of renal injury (NGAL) and urine osmolality Secondary 2. To assess the relative sensitivity of definitions of CIN based on changes in serum creatinine or cystatin C within 72 hours post contrast. 3. To determine the feasibility of a future multicenter randomized trial of a hypotonic fluid prophylaxis strategy for the prevention of radiocontrast nephropathy.
The purpose of this study is to determine if AzaSite Plus is effective and safe for the treatment of blepharoconjunctivitis compared to AzaSite alone and Dexamethasone alone.
Hypoxia (little of no oxygen) is considered to be an important characteristic of a patient's tumour that may help predict patient outcomes and/or help inform patient management decisions. 18F-FAZA Positron Emission Tomography (PET) can detect hypoxic tumours because 18F-FAZA accumulates in hypoxic tissues. This study is being done to learn more about the processes by which 18F-FAZA is absorbed, distributed, metabolized (built-up and broken down) and eliminated by the body.
An unmasked trial after bilateral implantation of AcrySof® ReSTOR®, SA60D3 IOL . Enrolled are at least 30 patients or as much as possible from the doctor's clinical practice perspective. 6 months follow-up after IOL implant in the 2nd eye
The purpose of this study is to determine whether plasma levels of lipopolysaccharide binding protein (LBP) are correlated with PBMN pro- and anti-inflammatory cytokine secretion, as well as with the development of severe infectious events in cirrhotic patients with ascites. As a secondary purpose, the study will evaluate the effect of a prophylactic administration of ciprofloxacin on LBP, cytokines and infections in the same patients.
To allow surgeons to obtain clinical experience on the postoperative uncorrected and best distance corrected visual acuities (UCVA and BDCVA) and corneal and refractive cylinder of the AcrySof Toric IOL.
Patients who present to a wound care center for management of their wounds will be evaluated clinically to establish if their wounds are chronic or acute. These patients will undergo standard of care management of their wounds. If debridement is indicated for the patient, the patient will be asked to participate in a study. Once the standard of care debridement is complete, the material debrided from the wound, instead of being discarded into a biohazard bag, will be prepared for shipment. The samples will then be shipped to the Center for Biofilm Engineering where microscopic evaluation will be conducted on the material. Conclusion will be made from that analysis.
Influenza is a common infection of the upper airways and lungs, and is caused by viruses. Cancer patients may need a stronger influenza vaccine than the general population to protect against influenza. The experimental vaccine is designed to be 9 times stronger than the standard vaccine, which may cause a stronger immune response against influenza in patients with a weakened immune system. The goal of this study is to compare the effects of a new experimental influenza vaccine to the effects of the standard influenza vaccine. One hundred bone marrow recipients, adult volunteers from the MD Anderson Cancer Center, 18 years of age or older, will participate in this study. They will be randomly (by chance) assigned to receive 2 doses of either the standard licensed influenza vaccine or the experimental influenza vaccine. Participants will be asked to complete 5 study visits and 3 telephone contacts. Study procedures include blood draws. The duration of participation is about 6 months.
Girls with spina bifida also have bladder problems. This is because they need temporary placement of a tube into the bladder to remove urine. This thin flexible tube is called a catheter. It can increase the risk of having bacteria in the urine. This in turn can lead to urinary tract infection (UTI). Some girls with spina bifida are given antibiotics. These are medicines used to treat infections caused by bacteria. The medicine is used to prevent UTI. However, long-term treatment with these medicines can have side effects. For example, the bacteria may become resistant to the antibiotics. Also, bacteria in the urine can persist. UTI can still occur in patients on antibiotics. UTI in girls occurs because bacteria migrate from the rectum to the vagina area. This gives the bacteria access to the bladder. Also, in girls with spina bifida, the access to the bladder is easier because of the catheter. Probiotics are friendly bacteria. They are available as dietary supplements and as food. They contain helpful bacteria. Yogurt is an example of a food that contains probiotics. The purpose of this study is to find out, if probiotics taken for 6 months can prevent UTI in girls with spina bifida. We will also try to find out whether changes in urine bacteria are associated with the taking of the probiotics. A vaginal and rectal swab will also be done to find out if taking probiotics has any benefits on preventing bacteria.
