Sensory Motor Transformations in Human Cortex
Recruiting
This research study is being conducted to develop a brain controlled medical device, called a brain-machine interface. The device will provide people with a spinal cord injury some ability to control an external device such as a computer cursor or robotic limb by using their thoughts along with sensory feedback. Development of a brain-machine interface is very difficult and currently only limited technology exists in this area of neuroscience. Other studies have shown that people with high spin... Read More

A Study of 2 Doses of EYE103 Compared With Ranibizumab (0.5 mg) in Participants With DME
Recruiting
EYE-RES-103 is a randomized, double masked pivotal study to evaluate the efficacy and safety of 2 dose levels of EYE103 in comparison with the active control, ranibizumab, in patients with diabetic macular edema (DME). In the first year, all 3 treatment groups will be treated every 4 weeks with either EYE103 or ranibizumab. Beginning at Year 2, the frequency of treatment for participants will shift based on a personalized treatment interval algorithm. Approximately 960 participants will be ent... Read More

The Effects of Endotracheal Suctioning on Pain and Serum Markers
Recruiting
The goal of this experimental study is to understand if endotracheal tube (ETT) suctioning increases pain and causes stress on the body in intubated adult ICU patients. These patients are already on ventilators, which means they need suctioning to keep their airways clear, but this procedure may be uncomfortable and cause stress. The main questions this study aims to answer are: Does ETT suctioning raise pain levels as measured by the Critical-Care Pain Observation Tool (CPOT)? Does ETT suctio... Read More
