The purpose of the challenge is to see if we, as the nutrition experts, can follow the dietary and physical activity guidelines promoted to the public. We have an opportunity to "practice what we preach." Scientific evidence demonstrates, knowledge is not enough to change ones'behaviors. It is through positive approaches and lifestyle changes that behavior can be altered. By experiencing the planning, work, and motivation required to make lifestyle changes we can all be better...
The purpose of this study is to compare the exercise-challenge in a cold chamber at 2-4°C to the gold standard the metacholine challenge in subjects showing symptoms of exercise-induced bronchoconstriction. The sensitivity and repeatability of the exercise test will be measured.
Hemophilia A is an inherited (genetic) disease where a protein, factor VIII (FVIII), which promotes blood clotting is missing or does not work properly. Individuals with hemophilia A are at risk for bleeding. Bleeding is prevented and/or treated with recombinant factor VIII (rFVIII), which is an FDA-approved treatment for Hemophilia A. Obesity is common among patients with hemophilia. Some studies have shown that obese hemophilia patients may be able to prevent bleeding with a ...
This is phase I, double blind, placebo-controlled safety and infectivity study of experimental human Norovirus genogroup GII.4 administered to healthy adults 18-49 years of age. Subjects susceptible to the human norovirus GII.4 challenge strain. The challenge study will be conducted in 2-3 cohorts of approximately 20 subjects each.Subjects will remain in the inpatient facility for at least four days following challenge and assessed daily for clinical and virologic evidence of n...
The objective of fluid challenge is to increase oxygen delivery (DO2) in order to improve/restore tissue oxygen consuption (VO2). However the fluid challenge volume to administer stills in debate, some studies recommend to administer 250 mL. Previous studies suggested that 500 mL of fluid challenge administration may improve cardiac output and oxygen delivery. The relation between the amount of fluid expansion and oxygen delivery and oxygen consumption was not yet been studied ...
The Fit-One trial involves three prospective, randomized waitlist-controlled studies. These studies evaluate the effects of One Drop's digital therapeutics solution with and without Fitbit devices on the social cognitive, behavioral, and health outcomes of people with diabetes. Fit-One is being tested on adults with type 1 diabetes (T1D) of all weights, and adults with type 2 diabetes (T2D) or pre-diabetes that are overweight or obese (BMI ≥ 25).
TB043 is a clinical challenge trial primarily to evaluate the safety of BCG challenge administered by the aerosol inhaled route in healthy, BCG naive UK adults. The trial will also look to evaluate and compare the amount of BCG recovered from the lungs as various points after challenge.
TB041 is a clinical challenge trial primarily to evaluate the safety of BCG challenge administered by the aerosol inhaled route in healthy, BCG naive UK adults. The trial will also look to evaluate and compare the amount of BCG recovered from the lungs and from the skin, following challenge by either the aerosol or the intradermal route.
The aim of the study is to assess the prevalence of bronchial hyperresponsiveness (BHR) in non-smoking adults with chronic cough and the prevalence of BHR in patients with upper airway cough syndrome (UACS) and gastroesophageal reflux disease (GERD), to evaluate the relationship between BHR and cough reflex sensitivity, to assess the diagnostic accuracy of methacholine challenge test (MCT) in cough variant asthma (CVA) with special regard to its discriminating cut off value bet...
This is a single-center, double-blind, placebo-controlled, Phase II vaccination and challenge study designed to confirm a human challenge model with E. coli strain LSN03-016011/A.
Sanaria PfSPZ Challenge With Pyrimethamine Chemoprophylaxis (PfSPZ-CVac Approach): Phase 1 Trial to Determine Safety and Protective Efficacy of Sanaria PfSPZ Challenge With Concurrent Pyrimethamine Treatment That Inhibits Development of Asexual B...
Background: - Malaria is a severe infection caused by a parasite. People can get malaria if a mosquito that carries the parasite bites them. Although malaria does not occur in the United States, many people in Africa, Asia, and South America do get malaria. In some cases, malaria can cause death. In 2013 alone, 584,000 people died due to malaria. Researchers want to find ways to prevent and treat malaria. Objective: - To find out if combining live, infectious mal...
The purpose of this study was to clarify the effects on health-related QOL of occupational therapy involving the adjustment of challenge-skill balance in the activity of elderly clients.
The purpose of the study is to discover any racial dissimilarity in the response of Natriuretic peptide (NP) system to acute metabolic influences such as a high carbohydrate challenge
An endotoxin challenge will be administered to healthy subjects to induce production of inflammatory markers. An investigational drug or placebo will be administered prior to the endotoxin challenge to assess the effect of the investigational drug on the markers of inflammation. Safety and tolerability will also be assessed.
Drug induced interstitial lung disease (DIILD) is caused by iatrogenic injury to the lung parenchyma and can be caused by over four hundred different drugs in humans. Diagnosing DIILD is a challenge for clinicians and radiologists as a positive diagnosis depends on exclusion of other causes including respiratory infection, occupational, recreational, and environmental exposures, specific respiratory disorders, and systemic diseases. The aim of this study is to qualify an objec...
This is a prospective controlled human challenge study consisting of two phases; Phase A: Development of a B. pertussis human challenge model; pilot to establish the standard inoculum Phase B: Development of a modified B. pertussis human challenge model
The objective of this study is to compare the ocular response to CAC (using food allergen sensitive patients) to the systemic response of a previously performed oral food allergen challenge in the same subjects. This study will investigate the potential utility of CAC as a predictive tool for identifying patient response to food allergen challenge and maximum tolerated dose.
The purpose of this study is to determine the difference (if any) in the result of the methacholine challenge (a test used by physicians in diagnosing asthma) when concentrations of methacholine are quadrupled versus doubled.
The present study is aimed to evaluate a bronchial allergen challenge with house dust mite and alternaria. Firstly, the years 2005, 2006, 2007, 2008 and 2009 will be retrospectively reviewed. Secondly, in 2010-2013, in the prospective part of the study the patients will undergo the bronchial allergen challenge to examine safety of the bronchial allergen challenge and change of allergen specific bronchial hyperreactivity before and after allergen specific immunotherapy.
The study is meant to establish a one-step challenge with grass-pollen in patients sensitized for grass-pollen. Therefore the investigators compare a multi-step challenge with grass-pollen with an one-step challenge in order to survey the repeatability and safety.
Perioperative fluid management is crucial for patients' outcome. Muller et al developed a "Mini-fluid challenge method " to predict fluid responsiveness and the efficacy. The investigators design the study to investigate the effectiveness of mini-fluid challenge test in prone position surgery.
This is a non-controlled, open-label, single-center, dose-escalation study to determine the safety, infectivity, and immune responses elicited from of the potential influenza virus challenge strain. The study objective is to determine the dose with the optimal safety profile and infectivity rate of the viral challenge strain in healthy volunteers for use in subsequent challenge intervention studies to test potential influenza vaccines and/or therapeutics.
We have identified areas of the brain that are activated in response to disease-related emotional information, following whole lung allergen challenge in asthma. We propose that activity in these central nervous system locations, as measured by fMRI, is associated with the intensity of allergic inflammation, provoked by segmental bronchial challenge, in the absence of significant airflow obstruction. We predict that this relationship will be mediated by changes in expression of...
