The purpose of the study is to evaluate the efficacy of study vaccine in the prevention of Reverse Transcriptase Polymerase Chain Reaction (RT-PCR)-confirmed RSV mediated- lower Respiratory Tract Disease (LRTD) over one RSV season when compared to placebo in adults aged 60 years and above and to demonstrate the non-inferiority of the vaccine in high-risk adults aged 20 to 59 years versus in adults aged 60 years and older in terms of humoral immune response.
It is generally accepted that the ventilatory system is not a limiting factor in physical exercise in terms of performance or exercise tolerance in healthy subjects. The ventilatory system would be oversized in relation to the stresses it has to cope with, even during maximum intensity exercise. However, some highly trained endurance athletes may be exceptions to this rule. A limitation of the expiratory flow is indeed sometimes found in these athletes, whose maximum values of ventilation can confront the mechanical limits of their ventilatory system. This phenomenon could be accentuated in elderly athletes (known as "master athletes") under the effect of structural and functional pulmonary alterations that accompany aging. Our hypothesis : What is the prevalence of exercise expiratory flow limitation in the master athlete and does it cause a decrease in physical performance via an acceleration of locomotor muscle fatigue?
Background: Dyspnea, like pain, is subjective and challenging to assess despite the large number of patients that report shortness of breath. Several studies have shown that physicians and nurses inaccurately assess patient dyspnea. Since respiratory therapists care for many patients at risk for dyspnea, an evaluation of their abilities to evaluate dyspnea is needed. Thus, the plan is to evaluate respiratory therapists' ability to assess a patient's dyspnea level, in addition to nurses and physicians. Methods: This is a prospective study to evaluate the agreement between dyspnea assessment by a patient and respiratory therapist, nurses, and physicians. The primary aim of this study will be to evaluate clinician ability to assess a patients dyspnea level. The secondary aim of this study is to identify patient characteristics that might influence clinician ability to assess dyspnea.

Plantar fasciitis (PF), a leading cause of persistent heel pain, results in almost a million physician visits annually. Conservative treatment is often the first line of management with insoles being frequently prescribed. While multiple studies have compared insoles based on the degree of customization to foot contour, the literature is lacking in data comparing insoles based on their material. In this randomized clinical trial, we compared the early effects of polyethylene (PE), polyurethane (PU), and carbon fiber insoles in the treatment of PF, using a set of patient-reported outcomes.
Current therapies for metastatic or unresectable Colon Cancer provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of metastatic or unresectable Colon Cancer. PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with metastatic or unresectable Colon Cancer
Current therapies for Stage IV Lung Cancer provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of Stage IV Pancreatic Cancer. PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with Stage IV Lung Cancer.
Current therapies for Refractory or Recurrent High-Grade Stage II - IV Non-Hodgkin's Lymphoma provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of Refractory or Recurrent High-Grade Stage II - IV Non-Hodgkin's Lymphoma. PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with Refractory or Recurrent High-Grade Stage II - IV Non-Hodgkin's Lymphoma.
Current therapies for Stage IV Pancreatic Cancer provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of Stage IV Pancreatic Cancer. PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with Stage IV Pancreatic Cancer.
This study will conduct tests in patients with primary chronic autonomic failure (CAF) to learn more about these disorders, which include pure autonomic failure, multiple system atrophy, Parkinson's disease with autonomic failure, and autoimmune autonomic neuropathy. Healthy volunteers and patients with primary CAF 18 years of age or older may be eligible for this study. Participants undergo some of the following tests: - Blood studies, including arterial catheter insertion to measure blood pressure and collect arterial blood samples, blood flow studies using sensors applied to the skin and a pressure cuff around a limb, and blood draw for genetic studies. - Bladder motility: Ultrasound test of bladder function. - Electrocardiogram and heart ultrasound. - Responses to changes in temperature: Warm water and then room temperature water are passed through watertight pads applied to the back and front of the body and body temperatures are measured. - Gastrointestinal motility: Bowel sounds are recorded using a microphone placed on the abdomen. - Lower body negative pressure: The lower body is placed into an airtight barrel-like chamber. Some air is sucked out of the barrel, causing blood to pool in the legs, as occurs during standing. - Lumbar puncture: A needle is inserted in the space between the bones in the lower back to collect a small sample of cerebrospinal fluid. - Microdialysis to measures levels of chemicals in the body fluid of certain tissues. A solution is passed through a thin tube inserted into the skin. Chemicals in the body tissues enter the solution. The solution is collected and the chemical levels are measured. - PET scanning: A nuclear medicine test to produce images of body organs. For patients with urinary problems, a catheter is inserted into the bladder before starting the scan. - Pupillometry: The pupil of the eye is measured using a special camera in a light-controlled room. - QSART. A small amount of a brain chemical is applied to the skin with a tiny amount of electricity, and the sweat in a nearby patch of skin is measured. - Measurement of saliva production, using a cotton-like material placed between the teeth and gums to absorb saliva. - Skin electrical conduction test, using sensors on the skin to measure sweat production. - Skin and core temperature measurements using sensors on the skin and in the ear canal. - Speech and swallowing assessment for patients with speech and swallowing difficulties. - Stress echocardiogram: A catheter is placed in the subject's arm for sampling blood or giving a drug while the subject exercises. During the test, blood pressure, pulse rate, and EKG are continuously monitored.
