Calcific aortic stenosis (AS) has become the most common cardiac disease after coronary artery disease and hypertension. Unfortunately no medical therapies have been proven to decrease either the progression of valve stenosis or the resulting adverse effects on myocardial remodeling and function. In light of the studies performed in PROGRESSA, it becomes obvious that: i) AS is a complex and actively regulated process that involves the interaction of several pathways including lipid infiltration and retention, chronic inflammation, osteogenic activation, and active mineralization within the valvular tissues; ii) AS is not a disease strictly limited to the aortic valve but rather a systemic disease that often involves calcification and stiffening of the aorta and impairment of LV function as a consequence of pressure overload. Our findings suggest that the dysmetabolic milieu linked to visceral obesity may accelerate the deterioration of the structure and function not only of the aortic valve but also of the aorta and of the left ventricle. These findings open new avenues of research and provide strong impetus for the elaboration of prospective studies focusing on the "valvulo-metabolic risk" in AS. The general hypotheses are: The metabolic abnormalities linked to visceral obesity accelerate (1) the progression of valvular calcification and stenosis, aortic calcification and stiffness; (2) the progression of myocardial fibrosis and dysfunction. The general objectives of the study are to elucidate the mechanisms implicated in the pathogenesis of AS and to identify the metabolic factors that determine the progression of: i) aortic valve calcification and stenosis; ii) myocardial fibrosis and dysfunction; and iii) clinical outcomes. This study will contribute to identifying the key metabolic determinants of AS progression and will pave the way for the future development of non surgical therapies for this disease. The results of this study would provide strong support to the realization of randomized trial to test the efficacy of lifestyle modification program or new pharmacological treatment aiming at the reduction of visceral fat and associated metabolic abnormalities in the AS population. Furthermore, this study will contribute to the identification of novel blood and imaging biomarkers of faster disease progression, which will help to optimize risk stratification and timing of AVR in the AS population.
The goal of this study is to collect blood samples from the umbilical cords of newborn babies, as soon as they are delivered, and to place these samples in the MD Anderson Cord Blood Bank. Your sample may be included in the National Cord Blood Inventory (NCBI) which is part of the CW Bill Young Cell Transplantation Program. The NCBI is a federally-supported program to assist in the collection of cord blood. Cord blood will be made available to patients through The National Marrow Donor Program (NMDP). These samples may then be offered to MD Anderson and other institutions for patients who need a bone marrow transplant and do not have a donor. The MD Anderson Cord Blood Bank will have the rights to release cord blood units to these institutions around the world according to established bone marrow transplant donor criteria, for a fee to cover costs. Cord blood samples that are collected and then do not meet the clinical requirements for patient use may also be used at MD Anderson or other institutions either for research or for quality purposes to improve cord blood banking procedures. If not suitable for patient use or for research purposes, the cord blood unit may be thrown away.
RATIONALE: Hypnosis may be effective in decreasing hot flashes in breast cancer survivors. PURPOSE: This randomized clinical trial is studying how well hypnosis works in treating hot flashes in breast cancer survivors.
the objective of this phase IV study: to establish the efficacy of elmex gel with a fluoride concentration of 1.25% compared with placebo by determining prevention of white spot lesions in patients wearing fixed orthodontic appliances.
In 2004, the Developmental Clinic of the Child Psychiatric Unit at Srinagarind Hospital, had 80 new pediatric cases of attention deficit hyperactivity disorder (ADHD) come for evaluation and intervention. The children were between 7-12 years of age. Most of them were treated with stimulant medication, (i.e. methylphenidate) to help reduce hyperactivity; however, both the parents and children needed special help to develop some techniques for behavioural management. Meditation has been used as an attention training method for many thousands of years, and was mostly involved with religious or spiritual practices in various parts of the world, especially in the eastern countries. Breathing meditation is a popular method which can be applied to all people without instructions that are too complicated. If meditation therapy, by breathing meditation which is specified to treat attention deficit hyperactivity disorders, benefits this group of patients, it would be very useful, culturally appropriate, cost-effective and would reduce the drugs used which will save the child from drug side effects.
This study will determine whether laparoscopic and open hernia repair have the same recurrence and complication rates in the under 60yr old age group. The overall financial costs of each repair will also be compared.
The objective of this pilot study is to examine the feasibility and safety of performing a larger trial to assess outcomes following treatment of meconium aspiration syndrome with surfactant lavage compared to bolus surfactant. Specifically, we will determine if surfactant lavage results in a more rapid improvement in physiologic outcomes (e.g. pulmonary compliance), as well as clinical outcomes (e.g. length of time on mechanical ventilation).
The hypothesis is that community-acquired pneumonia is usually a monomicrobial infection. Therefore, early detection of the etiology allows to select the most active, narrow-spectrum, and cheap, and less toxic antibiotic agent.
The purpose of the study is to describe the early signs and symptoms of the dystroglycanopathies, and to gather information that will be required for future clinical trials.
Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare immune system disorder that causes asthma, an excessive number of eosinophils (a type of white blood cell) in the blood, and the inflammation of blood vessels, or vasculitis. In order to properly treat EGPA, it is critical that the level of disease activity can be determined over the course of the disease. The purpose of this study is to determine new biological markers, or biomarkers, that may be used to assess the severity of this disease in people with EGPA.
