NCT01761006
The purpose of this research study is to determine whether exhaled nitric oxide (FeNO) goes up during an acute exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) and whether the level of exhaled nitric oxide returns to normal in the weeks after an exacerbation.
NCT03121547
While the analgesic effects of opioids are well known, evidence suggest that there are differences in the adverse dizziness of the different opioid types, which may influence the gait function differently. However, this has not been investigated scientifically under controlled conditions. Normal gait function is characterized by cyclic movements with a high degree of predictability. As such, the amount of kinematic variability can provide important information about a condition or an intervention that may affect the gait function . Three-dimensional gait analysis is a recognized method to assess changes in stride-to-stride variability associated with a medical condition or caused by an intervention. Thus, opioid induced changes in gait variability, and possible differences between opioid types, can be assessed objectively from differences in the variability of movements obtained from a three-dimensional gait analysis. The purpose of this study is to investigate differences in gait variability induced by two different single-dose opioid formulations and an inert placebo in healthy volunteers and knee osteoarthritis patients.

Noise-induced hearing loss affects an estimated 5% of the worldwide population, with 30-40 million Americans exposed to hazardous sound or noise levels regularly. Sources of noise may be occupational, blast noise, or recreational. Trauma to the inner ear can occur through transient hearing loss or permanent hearing loss. Although hearing recovers after temporary transient hearing loss, growing evidence suggests that repeated temporary transient hearing loss may lead to a permanent hearing loss. Currently, there are no treatments and there are no known medications that can be used clinically to prevent noise-induced hearing loss in humans. The long-term goal of this research is to find medications that can prevent noise-induced hearing loss. The purpose of the present pilot study is to evaluate zonisamide and methylprednisolone as medications to prevent temporary transient hearing loss in humans.
