15 Clinical Trials for Various Conditions
RATIONALE: Collecting and storing samples of tissue, blood, and body fluid from patients with cancer to study in the laboratory may help the study of cancer in the future. PURPOSE: This research study is collecting and storing blood and tissue samples from patients being evaluated for hematologic cancer.
We are studying virologic and/or immunologic parameters of HIV infection and other infectious or non-infectious immune deficiency diseases in order to better understand the pathogenesis of HIV. Because of the lack of an adequate animal model it is generally necessary to utilize human peripheral blood cells for studying aspects of either in vivo or in vitro HIV infection. We wish to be able to continue to elucidate many pathogenic aspects of HIV infection in relation to other infectious or non-infectious immune regulation and dysregulation using human peripheral blood mononuclear cells as a model.
This research trial studies metabolomic and other molecular profiling to identify predictive biomarkers for radiation toxicity and survival in patients with lung or brain cancers receiving radiation therapy. Studying samples of blood, urine, and tissue from patients with lung or brain cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer and predict which patients are at higher risk for developing radiation side effects and how well patients will respond to radiation treatment.
The aims of this protocol are: to collect and store diseased and normal tissue and body fluid samples from new and returning patients at St. Jude Children's Research Hospital (SJCRH), affiliated sites and collaborating institutions; to collect and store samples from relatives of SJCRH patients; to collect and store retrospective and prospective pertinent corresponding clinical and laboratory data on disease characterization, treatment, and outcome; and to serve as a source of human biological samples and corresponding laboratory and clinical data.
The purpose of this study is to evaluate the performance of the UpSpring Milkscreen Test for Alcohol in Breast Milk to detect alcohol in breast milk from lactating women.
The investigators are developing two new medical instruments: 1. the Intelligent Sensor Belt (ISB), and 2. the Body Composition and Hydration Status Analyzer (BC-HS-A). ISB serves the purpose of measuring calorie/ energy consumption of the human body during physical activity. The BC-HS-A measures the body composition, i.e. the fat and lean body mass and the hydration status i.e the amount of water inside and outside of the body cells. The goal of this pilot study is to obtain data from the investigators prototype medical instruments: 1. ISB, and 2. BC-HS-A during physical exercise and compare those results with readings of other commercially available instruments or exercise equipments. The investigators would be testing for technical feasibility and, through comparison with existing measuring devices, the reliability of the investigators prototype.
The Study investigates a new product, sFilm-FS, aimed to help controlling body fluid leakage in general surgery procedures, proposing its use as an adjunct to hemostasis and/or sealing.
The purpose of the study is to determine if black cohosh extract (BCE) administration in symptomatic postmenopausal women results in estrogenic stimulation of the breast, as determined by estradiol, pS2, FSH, LH, and PSA levels in nipple aspirate fluid.
Being able to accurately monitor patient bodily fluid levels during and after surgery is very important, as there are a number of complications that can arise if a patient's fluid levels become unbalanced, such as swelling within or pressure on various bodily organ systems. There are several different ways that physicians can monitor a patient's fluid balance during and after surgery, such as measuring the amount of urine output or the use of central venous catheters which measure the pressure in the veins entering the heart. Most of these techniques are invasive since they require tubes to be inserted into the body. A potential alternative would be to use a noninvasive technique such as electrical bioimpedance (BIA). Bioimpedance assessments work by using small electrical currents that can accurately predict both the water surrounding the outside of cells in the body, as well as the total amount of water in the entire body. Electrical bioimpedance assessments have been used to estimate patient swelling following surgery (edema), to measure the volume of blood the heart is pumping out, as well as to calculate body fat percentages. The goal of this study is to relate this technology to fluid shifts within the body that occur as a result of surgery, in particular, major intra-abdominal surgeries. By using bioimpedance during and after surgery, the investigators will compare the data collected with that calculated by using traditional measures of body fluid status, such as urine output and intraoperative blood loss. During the study, the bioimpedance monitors will not replace the standard bodily fluid monitors and will not interfere with their readings. Additionally, the electrical current produced by the bioimpedance monitors is too small for patients to feel and will not interfere with medical devices such as pacemakers.
This study is designed to help decide how much intravenous (IV) fluid should be given to pediatric trauma patients. No standard currently exists for managing fluids in critically ill pediatric trauma patients, and many fluid strategies are now in practice. For decades, trauma patients got high volumes of IV fluid. Recent studies in adults show that patients actually do better by giving less fluid. The investigators do not know if this is true in children and this study is designed to answer that question and provide guidelines for IV fluid management in children after trauma.
The purpose of this study was to evaluate long term efficacy and safety of treatment with solifenacin succinate (the study drug) in children with neurogenic detrusor overactivity after multiple dose administration.
The purpose of the APEX study is to determine whether carbohydrate-electrolyte beverage intake promotes fluid balance during exercise in the heat compared with water or placebo intake.
We propose to critically evaluate the effects of energy-yielding fluids and solids on acute appetite variables, daily food intake, and specific endocrine and metabolic response to food in the elderly. The results of these studies will provide further evidence to support that nutrition may provide safe and effective non-pharmacological therapies to counter the compromised regulation of energy balance experienced by many elderly people.
In patients with moderate to severe thermal injuries (\> 20% TBSA) adequate fluid resuscitation is the main priority to achieve successful outcomes. Soon after burn injury substantial amounts of fluid accumulate rapidly in the wound while more is lost in the third space. Without intervention this process leads to hypotension and shock. The Parkland formula was devised to calculate how much intravenous (IV) fluid, i.e. crystalloids, is needed for adequate resuscitation during the first 24 hours post-burn. However, IV resuscitation can lead to overexpansion of (third space) volume, leading to severe complications such as compartment syndrome or pulmonary edema. In major population centers, catastrophic events causing mass casualties will disrupt many hospital and emergency services, potentially delaying acute IV fluid resuscitation. Burn patient case reports have shown that oral rehydration therapy (ORT) used to supplement or in place of IV therapy is efficacious. ORT could be easily applied in mass burn casualties. ORT is generally known in the third world for treating life-threatening dehydration due to diarrhea. The glucose-sodium co transport mechanism enables the affected human intestine to absorb a sufficient amount of water and electrolytes to replace large fluid losses due to severe diarrhea, even under adverse field conditions. No electrolyte disturbances have been recorded in such cases. Studies on enteral resuscitation in animal burn models showed high rates of small intestinal absorption which should be adequate for resuscitation following major burn injury. The optimal composition of oral rehydration solution for resuscitation in burn wounds has not been determined. In cholera patients, Ceralyte® has proven superior to the World Health Organization Oral Rehydration Solution, increasing fluid absorption of the intestine. The Ceralyte® 90 solution, with 90mEq/L sodium and a low osmolarity of \<275mOsm, may also contribute to optimal intestinal fluid uptake without causing electrolyte disturbances in thermal injury. ORT use might reduce the occurrence of compartment syndrome and pulmonary edema since fluid is regulated by the intestine according to physiologic requirements. The investigators propose to conduct a prospective study using Ceralyte® 90 to show that oral resuscitation therapy (ORT) in burns can reduce the total amount of IV fluid needed for adequate resuscitation and to test the efficacy and safety of ORT in the resuscitation of burn patients.
This study seeks to understand the physical, physiologic and biologic features that predispose a woman to the development of obstructive sleep apnea once they are exposed to the cardiopulmonary and metabolic physiological changes of pregnancy. Knowing these specific predictive factors can help identify a population at risk and guide clinicians to develop suitable targeting screening strategies.
