Increasing evidence suggests an important role of activation of the sympathetic nervous system (SNS) in the clinical phenomena of heart failure with normal left ventricular ejection fraction and hypertension. The current study aims to evaluate efficacy and safety of renal sympathetic denervation for the modulation of the SNS in patients with heart failure with normal LV ejection fraction.
To demonstrate safety and effectiveness of nMARQ Catheter System [nMARQ] compared with THERMOCOOL® Navigational Family of catheters in treating subjects with drug-refractory symptomatic paroxysmal atrial fibrillation (PAF).
P31 nuclear magnetic resonance (RMN) Spectroscopy (SRM P31) has currently being poorly used in the field of sarcopenia. The aim of the CAMUS study is to investigate the feasibility a protocol of SRM P31 at rest, during and after a standardized physical task. The secondary objective is to compare the metabolism of tyhe skeletal muscle tissue assessed by SRM P31 in young and older individuals. A pilot study, cross-sectional study will be conducted. Ten healthy sedentary 70+ years males and 10 sedentary 25 to 30 years old male will be included. Level of physical activity, physical performances, will be assessed at baseline. RMN (T1; tractography and SRM P31) will be performed. SRM P31 will be performed at rest, during and after an exhausting muscle task at 70% 1-RM. Feasibility will be judged on the rate of valuable variables recorded (>90%) inorganic phosphate (iP), phosphocreatine (PCr) and isoform of adenosine triphosphate (ATP : alfa, beta, gamma).
Background: The pulmonary rehabilitation effects on various outcomes of COPD are well known. However, they may be lost over time due to poor adherence to therapy with absence of regular exercise maintenance in long term, disease progression, comorbidities, falls incidence and higher exacerbations frequency. Currently, the main focus is to make the patient more active and ensure the benefits maintenance. However, few studies have been concerned with the aim of to investigate the long-term effect of this intervention and the relationship of the change promoted in important outcomes of the disease with its morbidity and mortality. Design: Non-controlled clinical trial, prospective and longitudinal. Setting: Outpatient pulmonary rehabilitation program in Florianopolis, Brazil Subjects: Patients with COPD (GOLD II-IV). Interventions: Pulmonary rehabilitation program (PRP) based on physical training, conducted over 24 sessions supervised, three times a week, including aerobic training in treadmill and resistance training for upper and lower limbs. Main measures: Before, post-PRP, 6 months post-PRP and 12 months post-PRP will be measured Spirometry or Total Body Plethysmography, Triaxial Accelerometry by Dynaport Activity Monitor, Glittre ADL-Test to evaluated functional capacity and functional performance, Six-Minute Walk Test distance on tracks of 20 and 30 meters, muscle oxygenation variables by NIRS PortaLite®, force platform NeuroCom® SMART Equitest®, Timed Up and Go Test, Berg Balance Scale, Activities-specific Balance Confidence, Falls Efficacy Scale - International - Brasil, London Chest Activity of Daily Living score, Modified Medical Research Council score, Saint George Respiratory Questionnaire score, COPD Assessment Test score and Hospital Anxiety and Depression Scale, Behavioural Regulation in Exercise Questionnaire-2, Basic Psychological Needs in Exercise Scale, General self-efficacy scale, COPD self-efficacy scale, Pulmonary Rehabilitation Adapted Index of Self-Efficacy. The death cases and numbers of exacerbations and hospitalizations will be measured by monthly phone calls after PRP.
Chronic neuropathic pain affects millions of individuals worldwide. It causes marked reduction of health, utility and quality of life and represents a considerable economic burden to society due to loss of work capacity and large treatment expenses. The proposed project will explore new and rational methods for deep brain stimulation treatment of patients with severe chronic neuropathic pain, resistant to conventional treatment. Deep brain stimulation is a neurosurgical procedure in which a small stimulating electrode is implanted into deep brain areas. Furthermore, we will utilize new positron emission tomography neuroimaging and a new prototyped technology, called targeted transcranial magnetic stimulation, to predict the outcome of deep brain stimulation and localize brain regions with maximum symptom relief for each patient. This will optimize the selection of patients for deep brain stimulation and provide a rational customized choice of brain target for each patient, without surgical intervention. Novel techniques will be validated on healthy volunteers and at the same time provide new insights into the mechanisms underlying brain stimulation and pain perception. The project has great clinical impact, potential for innovative development and industrial spin-out, facilitates exchange for Danish research talents and senior researchers with Stanford University and California Pacific Medical Research Institute in San Francisco, and unites world leading experts in pain research and clinical treatment to achieve its goals.
This phase II trial studies how well peginterferon alfa-2b works in treating younger patients with craniopharyngioma that is recurrent or cannot be removed by surgery. Peginterferon alfa-2b may interfere with the growth of tumor cells and slow the growth of craniopharyngioma.
This phase II trial studies the effects of interstitial photodynamic therapy in patients with head and neck cancer that has come back. Interstitial photodynamic therapy uses a combination of laser light and a light-sensitive drug called porfimer sodium to destroy tumors. During treatment a laser light is used to activate the drug. Interstitial photodynamic therapy may be an effective treatment for head and neck cancer.
The overall goal of this project is to develop sensitive and objective clinical research tools for the assessment of postural control of the trunk. In order to accomplish this goal, we aim to quantify balance performance in an unstable seated task. Specifically, the investigators will quantify balance performance in low back pain participants before and after osteopathic manipulative treatment. The investigators hypothesize that there will be a significant improvement in balance performance after a single session of osteopathic manipulative treatment as well as after 4 sessions of osteopathic manipulative treatment and this improvement will be greater than any learning effect. A secondary objective of this study is to quantify differences in patient-oriented outcome measures (e.g., self-reported pain, disability) in low back pain participants before and after osteopathic manipulative treatment. The investigators hypothesize that there will be a significant improvement in these self-reported outcomes following osteopathic manipulative treatment. The association between improvement in postural control parameters and patient-oriented measures will also be explored.
The purpose of this study is to determine if erlotinib given orally along with concurrent palliative irradiation to lung cancer improves local control compared to those treated with radiotherapy alone.
