RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. Selenium may be effective in preventing cancer. It is not yet known which dose of selenium may be most effective in preventing cancer. PURPOSE: Randomized pilot study to determine the effectiveness of selenium in preventing cancer in healthy people.
The purpose of this study is to determine the amount of selenium as selenomethionine that is required to optimize selenoprotein P in selenium-deficient Chinese subjects
RATIONALE: Selenium supplements may stop or delay the development of prostate cancer in patients at high risk of prostate cancer. It is not yet known which dose of selenium may be more effective in preventing prostate cancer. PURPOSE: This randomized phase III trial is studying how well selenium works in preventing prostate cancer.
This study is being conducted to determine if patients with cirrhosis (liver disease) are selenium deficient. The effect of supplementation with two chemical forms of selenium on plasma selenium biomarkers will be determined and correlated with the severity of the liver disease.
The purpose of this study is to determine whether patients with liver cirrhosis can improve their selenium nutritional status by taking supplemental selenium.
RATIONALE: Selenium may prevent or slow the growth of prostate cancer. PURPOSE: This randomized phase II trial is studying how well selenium works in treating patients with prostate cancer.
As one of the essential micronutrients, selenium has important biological functions. However, an effective and convenient method for evaluation of selenium nutritional status has not yet been established. Previous literature has disclosed effect of selenium deficiency on inactivating glutathion peroxidase and deiodinase, which may cause decreased conversion from thyroxine ( T4) to triiodothyronine (T3). A case-control study is designed to demonstrate the association between sel...
This intervention study will investigate the relationship between consumption of selenium-fortified biscuits fortified with selenium-enriched yeast (approximately 60mcg of selenium per day for 14 days) and both plasma selenium concentration and plasma selenoprotein P concentration in adult human volunteers. It will also investigate how selenium-status may affect changes in sensory perception of the fortified biscuits when consumed for 7 and 14 consecutive days (Flavour-Nutrient...
RATIONALE: The use of nutritional supplements, such as selenium, may stop prostate cancer from growing. Internal radiation, such as brachytherapy, uses radioactive material placed directly into or near a tumor to kill tumor cells. Giving selenium before brachytherapy may be an effective treatment for prostate cancer. PURPOSE: This randomized phase I trial is studying selenium to see how well it works compared to placebo in treating patients who are undergoing brachytherapy for...
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. The use of selenium may be an effective way to prevent prostate cancer in patients who have neoplasia of the prostate. PURPOSE: Randomized phase III trial to study the effectiveness of selenium in preventing prostate cancer in patients who have neoplasia of the prostate.
Penn State Milton S. Hershey Medical Center researchers are trying to compare the effects of two different forms of selenium (selenium yeast and selenomethionine) on blood selenium levels and biomarkers of oxidative stress as primary endpoints. One in six men are at risk of getting prostate cancer in their lifetime. Participants will be asked to take over-the-counter selenium yeast supplements and selenomethionine or a placebo for nine out of twelve months.
The primary objective of this study to assess the effectiveness of selenium compared to placebo in reducing the lymphedema in-patients with breast cancer. Secondary objectives are to assess the impact of selenium on patient’s quality of life and to assess the incidence of adverse effects of selenium therapy.
Previous literature has found potential association between selenium deficiency and inactivated glutathione peroxidase and deiodinase, which may contribute to subsequent elevation of T4 and ratio of T4/T3. Conduction of a case-control study (ID: Liuyanping3) has been applied on Clinicaltrials.gov to further elucidate effect of selenium deficiency on thyroid function. Based on its data, the investigators will perform a randomized, placebo-controlled,single-blinded crossover stud...
RATIONALE: Studying tissue samples in the laboratory from participants receiving treatment on the Selenium and Vitamin E Cancer Prevention Trial (SELECT) SWOG-S0000 may help doctors predict a participant's response to treatment and help plan the best treatment. PURPOSE: This phase III trial is studying the effect of vitamin E and/or selenium on colorectal polyps in men enrolled on SELECT Trial SWOG-S0000.
The aim of this study is to determine whether selenium supplementation leads to changes in selenium levels and gene expression profiles in prostate tissue.
The aim of the study is to investigate the relationship between dose and form of selenium on immune function, and to identify functional markers of selenium status.
RATIONALE: Aging may affect a person's vision. Vitamin E and/or selenium may help prevent cataracts or age-related macular degeneration in older men receiving these drugs for the prevention of prostate cancer. PURPOSE: This clinical trial is studying vitamin E and/or selenium to see how well they work in preventing cataract and age-related macular degeneration in older men enrolled on SELECT clinical trial SWOG-S0000.
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. The use of selenium and vitamin E may stop cancer from growing or coming back. PURPOSE: This randomized phase III trial is studying giving selenium together with vitamin E to see how well it works compared with a placebo in preventing cancer progression and recurrence in patients with early-stage bladder cancer.
RATIONALE: Brassica juncea that contains high amounts of selenium may slow the growth of cancer cells. Drugs used in chemotherapy, such as irinotecan and capecitabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving high-selenium Brassica juncea together with combination chemotherapy may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of high-selenium...
Selenium is a trace element essential to human health.Selenium protection against cellular damage by oxygen radicals is accomplished through selenoproteins. Ischemic stroke is associated with the generation of oxygen free radicals resulting in a condition of oxidative stress. Supplementing stroke patients with antioxidant nutrients may improve survival.
Does an oral selenium supplement increase blood levels of antioxidants in patients with established, smoking-related lung disease? Members of our study group recently discovered that elevated levels of the anti-oxidant GPx-1 may be protective against heart disease. We are studying whether selenium supplementation will improve GPx-1 levels.
Selenium is a trace element which is deficient in hemodialysis patients .The aim of this study is to evaluate the effect of selenium supplementation on oxidative, inflammatory and nutritional markers in hemodialysis patients .
Septic shock is a frequent syndrome with a 45% mortality rate despite intensive care unit (ICU) care, where free radicals may play a key role, and a >40% decrease in plasma selenium concentration is observed. Selenium is a trace element with both indirect enzymatic anti-oxidant, and direct oxidant properties. High dose of sodium selenite administration could increase antioxidant cells capacities, and reduce inflammation by a direct paradoxical pro-oxidative effect. We conduct a...
Selenoenzymes play a major role in protecting cells against lipid peroxidation and they are involved in the inflammatory response regulation. The degree of selenium deficiency correlates with disease severity and the incidence of mortality in critically ill patients. The aim of our study is to evaluate, if high dosis selenium supplementation (loading dose 4000 μg, daily dosage 1000 μg) results in a significant reduction of inflammation-induced organ dysfunction and length of ...
The aim of this study is to evaluate the effect of zinc gluconate and/or selenium yeast supplementation during six months on clinical (glucose, cholesterol, triglycerides, bone mineral density and body composition) and immunological (oxidative stress, CD4+ count and pro-inflammatory cytokines) parameters in a population with HIV diagnosis on antiretroviral treatment.
