Participants will complete a self-selected intensity of exercising over a 6 month period, with detailed clinical assessments at commencement and completion to determine the rate of progression of parkinsonism and gait abnormalities
TPMT is a key enzyme in the metabolism of thiopurines. TPMT polymorphisms have been described and are associated with a decrease activity of such enzyme. Therefore, a higher risk of developing toxicity is present in patients requiring these drugs, which are indicated in acute lymphoblastic leukemia, as well as, immunosuppressors after organ transplantation. The frequency of heterozygotes polymorphisms ranges from 3 till 12 %, in different populations. Homozygous patients have a lower frequency, estimated 1 in 300 individuals. The frequency of such polymorphisms in mestizos mexican population has not been analyzed, and we considered important to determine this frequency in healthy and patients requiring thiopurines, particularly acute lymphoblastic leukemia.
Secondary hyperparathyroidism (HPT) is a known complication of chronic renal failure. Elevated concentrations of parathyroid hormone (PTH) play a role not only in the pathogenesis of renal bone disease, but also in the development of cardiovascular risk factors such as disturbed lipid metabolism, glucose intolerance, and hypertension. HPT is also known to play an important role in the development of structural abnormalities of both large arteries and the heart (left ventricular hypertrophy, interstitial fibrosis). In the last couple of years there has been increasing evidence from animal studies that the endothelium is a target organ of PTH. Hypothesis: PTH has clinically relevant effects on renal hemodynamics, renal function and endothelial function. Aims: 1. To evaluate the effect of parathyroidectomy (PTX) on renal hemodynamics in stable renal transplant recipients 2. To evaluate the effect of PTX on endothelial function in stable renal transplant recipients/chronic kidney disease (CKD) stage 5 patients 3. To evaluate the effect of PTX on blood pressure in stable renal transplant recipients/CKD stage 5 patients
This study involves research to investigate how estrogen affects women of childbearing age and its correlation to Systemic Lupus Erythematosus. The findings from this study might help determine how body cells, called T Cells, react to estrogen. The study will seek to determine if cells from women with Lupus, react differently from cells in persons without Lupus. We will attempt to identify genetic factors that determine the effects of estrogen on Lupus cells.
This study aims to show that the MedGem indirect calorimetry measurement device will be feasible to use in children with GVHD. Also, it aims to show that children with chronic GVHD will have elevated REE that is not adequately predicted by standard equations.
Participants will be diagnosed with localized prostate or breast cancer and be scheduled to undergo external beam radiation therapy. Participants will either receive a placebo or organic germanium to be taken 5 times a day starting the day of their first radiation and continuing through the 1 month follow-up visit. Weekly Quality of life forms will be completed through the one month follow up visit and then at the 3 month follow up visit. Labs will be done prior to the start of treatment, at the end of treatment and at the one and three month follow-up visits.
The purpose of this study is: 1. To determine the frequency of cardiovascular diseases in patients with OSA, obese, overweight, and lean (BMI<25) 2. To analyze the CPAP treatment over the clinical evolution of OSA patients 3. To determine if OSA is a independent predictor of cardiovascular risk
Obesity is a growing epidemic and is associated with an increased risk of heart attack and stroke. The investigators know that obesity leads to abnormalities in how the blood vessels and the heart function and that these abnormalities are an important cause of this increased risk in obese individuals. While improvements in these abnormalities have been reported with marked weight reduction (eg surgery) and lifestyle changes including exercise training, it is not clear that these abnormalities can be substantially reversed with standard dietary interventions. Additional information is needed regarding the degree of weight loss required, the time course of these improvements, nor the mechanisms. All of these have major implications for the potential role of weight loss in the management of these patients. The investigators will assess the effects of dietary induced weight loss in both the short and long term on the function of blood vessels and the heart, and the relationship of any changes with markers of inflammation that are present in obesity. By understanding the factors that are important in reversing these abnormalities in obesity the investigators will be better to identify and reduce heart attack and stroke in obese individuals in the future.
RATIONALE: Androgens can cause the growth of prostate cancer cells. Androgen ablation therapy may lessen the amount of androgens made by the body. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving androgen ablation therapy together with docetaxel is more effective than giving androgen ablation therapy alone in treating patients with advanced prostate cancer. PURPOSE: This randomized phase III trial is studying androgen ablation and docetaxel to see how well they work compared with androgen ablation alone in treating patients with advanced prostate cancer.
Intracranial aneurysm treatment with coil embolization is associated with relatively low complete occlusion and high recanalization rates. The investigators evaluate whether Willis covered stent implantation yields angiographic and clinical results superior to those with coil embolization.
