Filter by:This study seeks to determine the safety and immunogenicity of a series of 3 primary vaccinations and a booster vaccination of Recombinant ricin toxin A-chain 1-33/44-198 (rRTA 1-33/44-198) vaccine (RVEc) at 10 or 20 μg intradermally (ID). This study is evaluating if RVEc will display an acceptable safety profile as determined by adverse event (AE) data and if RVEc will elicit anti-ricin antibody titers and ricin toxin-neutralizing antibodies in vaccine recipients.

This study is evaluating if RVEc will display an acceptable safety profile as determined by adverse event (AE) data and if RVEc will elicit anti-ricin antibody titers and ricin toxin-neutralizing antibodies in vaccine recipients.
This clinical trial should prove that selenium can treat arsenic exposure in humans by promoting excretion. The new trial differs from previous trials in that participants will be maintained in a local clinic and provided with food and water from their home villages. The purpose of this study to determine the fate of selenium supplements in feces, urine and blood of volunteers living in conditions of high arsenic load in drinking water. The use of a clinic will enable monitoring of all intake and excretion of both arsenic and selenium, and will ensure that participants take their selenium doses or placebo as appropriate. This proof of concept is absolutely essential groundwork for any remediation strategy involving selenium supplements.
In this study, the investigators will collect EEG data in normal, healthy volunteers without a history of prior brain injury. This data will be analyzed by computer (quantitative, or qEEG) and stored in a normative database so that, in the future, the investigators can better understand and characterize the brain damage that can result from carbon monoxide (CO) poisoning and other types of brain injury.
The purpose of this study is to evaluate a possible role of intravesical Hyaluronic Acid in reducing local toxicity of Bacillus Calmette Guerin (BCG) used to treat bladder urothelial cell carcinoma.
We hypothesize that salbutamol will speed removal of alveolar fluid compared to atropine alone in OP poisoned patients. We propose to compare the effect of two stat doses of nebulized salbutamol (2.5 mg; 5.0 mg), with nebulized saline placebo, in symptomatic patients receiving standard resuscitation with atropine, oxygen, and fluids after poisoning with OP pesticides. 25 patients will be randomised to each arm (total 75 patients). Primary outcome will be oxygen saturation's over the following 60 min during resuscitation. Secondary outcomes will include atropine dose administered, speed to stabilization, aspiration or pneumonia, intubation, tachydysrhythmias, and mortality. A positive outcome will result in design of a large definitive phase III study.
Organophosphate pesticide poisoning causes close to 300 000 deaths per year worldwide. Many patients who ingest organophosphates require ventilation; of these patients approximately 50% die. Much of the mortality in these ventilated patients is secondary to intermediate syndrome. This is because OP pesticides inhibit acetylcholinesterase, causing an excess of acetylcholine at nerve synapses and the neuromuscular junction (NMJ). At the NMJ, the excess acetylcholine causes overstimulation and damage, which may lead to sudden respiratory arrest or prolonged ventilation and its associated complications. The investigators believe that blocking these receptors using a neuromuscular blocking agent such as Rocuronium will protect the NMJ from damage and thus prevent intermediate syndrome and reduce number of intubated days and mortality. In this pilot randomised controlled trial Rocuronium, a competitive nicotinic receptor antagonist, will be used to bind to the receptor at the neuromuscular junction and to block the effects of the accumulated acetylcholine. The effects of OP pesticide on cholinesterase in the blood will then be monitored and Rocuronium withdrawn using Sugammadex as the OP is eliminated from the body.
To evaluate the effectiveness of Pralidoxime, a drug used for treatment of pesticide poisoning (Organophosphorous poisonings)
The primary purpose of the protocol is to evaluate the StO2 performance measured at the admission to the emergency department to identify hemodynamic failure at the admission or within the first three hours of monitoring patients with drug poisoning. The study hypotheses are: - The early detection of hypoperfusion by StO2, essential to prevent the development of collapse. - To limit hemodynamic failure effects, reduce morbidity and mortality of drug poisoning, hospital stay and cost.
The purpose of this study is to evaluate the safety and immunogenicity of a single 50-μg booster dose of RVEc. Subjects will be recruited from the cohort that received three 50-μg doses of RVEc in a Phase 1 trial (NCT01317667).
