Filter by:The primary purpose of this study is to demonstrate that changes in plasma levels of circulating neurohormones (mainly BNP and NT-proBNP), measured at rest and post-exercise correlate with exercise functional limitation (assessed by exercise peak VO2) and exercise ultrasonic parameters (as left ventricular filling, obstruction, and mitral regurgitation)
The purpose of RHYME is to evaluate the safety and efficacy of ranolazine in Hypertrophic Cardiomypathy patients with chest pain or dyspnea despite treatment with standard medical therapy. This is a small, pilot, open-label (non-randomized) study of an approved drug for the treatment of angina in a novel patient population (adult patient population with hypertrophic cardiomyopathy).
The goal of this study is to compare the perioperative and postoperative characters of plasmakinetic enucleation of the prostate(PkEP) with bipolar TURP(B-TURP) for BPH patients with large prostate.
Altered contour of the lower face is a frequent complication of human immunodeficiency virus (HIV). HIV facial lipoatrophy or loss of facial fat commonly results from antiretroviral therapy. Posterior cheek enlargement leading to a bulky and widened lower facial contour can also be seen in HIV. These changes can lead to significant cosmetic disfigurement and have an enormous psychosocial impact on patients. They also make individuals vulnerable by making them recognizable as persons living with HIV. Posterior cheek enlargement has not been well characterized. Both the parotid salivary gland and the masseter muscle are located in the posterior cheek region. Although parotid gland enlargement in a common complication of HIV, it is unknown whether enlargement of the masseter muscle also contributes. The investigators plan to study posterior cheek enlargement in HIV positive individuals. The investigators also plan to use botulinum toxin A as a novel treatment to improve the altered lower facial contour seen in HIV. This treatment has already demonstrated efficacy in HIV negative individuals with enlargement of the masseter muscle. Botulinum toxin has also been used safely in the salivary glands in individuals with excessive drooling resulting from neurological disease. In a trial HIV+ patient, the investigators have already demonstrated the efficacy of using botulinum toxin A in the treatment of posterior cheek enlargement, resulting from both parotid and masseter muscle enlargement. The investigators anticipate this study will increase our understanding of posterior cheek enlargement in HIV and lead to the development of a novel treatment for this important complication. The investigators hypothesize that posterior cheek enlargement in HIV+ patients will in some cases result from both masseter muscle hypertrophy as well as parotid gland enlargement. The investigators also hypothesize that the treatment of posterior cheek enlargement with botulinum toxin A will result in a more aesthetically appealing lower facial contour in HIV+ patients. This has already been demonstrated in a trial HIV+ patient, in which there was a dramatic change in the volume of the masseter muscle and parotid gland 12 weeks after treatment with botulinum toxin A.
Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiac disease, is a cause of disability including heart failure, atrial fibrillation, and sudden death, with an annual mortality varying from 1% to 6%. Obstructive sleep apnea (OSA) is extremely common among patients with established cardiovascular disease, including hypertension and atrial fibrillation and when present may contribute to worse cardiovascular outcome. Although patients with HCM do not necessarily have typical characteristics of patients with OSA, such as obesity and increasing age, there is recent evidence that OSA is extremely common among patients with HCM, with a prevalence ranging from 32% to 71%. The presence of OSA among patients with HCM is independently associated with worse structural and functional impairment of the heart, including atrial and aorta enlargement, worse New York Heart Association functional class, and worse quality of life. Therefore, the recognition and treatment of OSA is a new area of research that may impact in the management of patients with HCM.
Cardiac amyloidosis are related to the accumulation of fibrillar proteins in the extracellular leading to disruption of the cardiac tissue architecture. Amyloidosis in transthyretin (TTR) are the most common hereditary amyloidosis but remain poorly studied at heart. This is serious and deadly. The prevalence of TTR amyloidosis is probably underestimated in hypertrophic cardiomyopathy (HCM) often of unknown etiology because of the lack of systematic implementation of myocardial biopsy because of their side effects.
This investigation is a prospective, randomized, single-blinded and multicenter design. The purpose of this study is to evaluate the benefit of atrial-synchronous biventricular (BiV) pacing in severely symptomatic hypertrophic obstructive cardiomyopathy (HOCM) patients with severe Left Ventricular Outflow Tract (LVOT) obstruction implanted with a Cardiac Resynchronization Therapy - Pacing (CRT-P) device. Randomization - Implant will be performed (CRT-P). - Patients will be randomized 1:1 to either Treatment Group (Optimized Biventricular (DDD) pacing) or Control Group (Back-up Atrial (AAI) pacing) during the first 12 months: - Treatment Group. The patient´s device is programmed to optimized DDD BiV pacing - Control Group. The patient´s device is programmed to back-up pacing AAI. - After 12 months, the patients initially randomized to the Treatment Group (Optimized DDD Pacing) will continue in the same group. The patients initially randomized to Control Group (AAI Back-up Pacing) will be changed to the Treatment Group (Optimized DDD Pacing). And all the patients will be followed 12 months more.
The study's objective is to compare the global scar outcomes in those treated with silicone only therapy (SOT) versus silicone pressure garment therapy (SPGT) for the prevention of hypertrophic scarring in children with skin grafts after traumatic skin injury.
The aims of the presented study are as follows: 1. To evaluate the endothelial function and arterial stiffness in a large cohort of prevalent CKD patients by means of non-invasive applantion tonometry. 2. To evaluate the association between the serum levels of the representatives of the various classes of uremic toxins and markers of endothelial function and arterial stiffness. 3. To evaluate the association between markers of inflammation and oxidative stress and markers of endothelial function and arterial stiffness. 4. To evaluate the association between echocardiographic parameters and markers of arterial stiffness
Rationale: The consumption of dietary protein immediately after exercise is necessary to maximally stimulate muscle protein synthesis rates (24, 37). Recent work suggests that the type of protein consumed (e.g., animal vs. plant-derived proteins) during post-exercise recovery can affect the amplitude of acute increases in muscle protein synthesis rates (25, 31). Specifically, consumption of bovine milk proteins immediately after a single bout of resistance exercise stimulates muscle protein synthesis rates greater than consumption of an isonitrogenous soy-protein beverage (31, 37). Importantly, consumption of milk promotes greater hypertrophy than soy after resistance training (10). Thus, it is generally assumed that the acute muscle protein synthetic response predicts long-term training outcomes, such as hypertrophy. Currently, a great amount of work has been carried out to study the effects of consuming milk proteins on muscle protein synthesis rates after resistance exercise (5, 7, 26, 32). However, very little is known about the effects of other types of high-quality animal proteins, such as beef, on stimulating post-exercise muscle protein synthesis rates. Further describing the muscle protein synthetic response after consumption of other types of high-quality animal proteins will provide valuable information for individuals with milk allergies, lactose intolerance, or simply a strong dislike of dairy products. Objective: To investigate whether the in vivo post-resistance exercise muscle protein synthetic response is augmented when minced beef is ingested as compared to an isonitrogenous-matched milk protein beverage in healthy young men. Study design: Crossover, randomized Study population: 12 healthy young males (18-35 y). Intervention: Subjects will perform resistance exercise and consume either a piece of meat (135 grams, 35 g of protein) or an isonitrogenous-matched milk protein beverage on two separate test days. In addition, continuous intravenous tracer infusions will be applied, with plasma and muscle samples collected. A two week 'wash-out' period will be included between trials. Main study parameters/endpoints Primary endpoint: Muscle protein synthetic rate, expressed as fractional synthetic rate (FSR). Secondary endpoints: Rate of protein digestion and absorption and whole body protein balance.
