The Columbia Otolaryngology Department is interested in understanding the intersection of vaping, smell, and taste and their impact on individuals' preferences for certain flavors. Participation will involve answering a series of questionnaires in addition to completing a formal evaluation of your smell and taste with standardized measurements. You can…
This research study will look at a newer treatment option for Barrett's Esophagus (BE) which uses nitrous oxide to freeze unwanted tissue. The most commonly used treatment method is Radiofrequency Ablation (RFA) which uses heat to destroy the pre-cancerous tissue. Nitrous Oxide ablation using the C2 CryoBalloon Focal Ablation System, an FDA-cleared…
The use of electronic cigarettes, also known as e-cigs or vaping, has increased among former smokers and young adults who have never smoked. Relatively little is known, however, about their health effects (whether they are adverse, have no effect, or are beneficial). The purpose of this research study is to evaluate (1) the association of e-cig use with…
This is a four-session study in which we will be recruiting existing cigarette smokers to explore the competitive dynamics between memory encoding and memory retrieval. To participate, you will first go through a phone screening to determine eligibility and learn about the study. Then you will be asked to visit our facility at the Morningside Campus of…
C2 Therapeutics is currently enrolling patients to participate in the Coldplay 3 clinical trial. Coldplay 3 is evaluating the effectiveness of the Coldplay CryoBalloon Focal Ablation System in patients with Barrett's esophagus who have not yet received treatment. Participants will undergo treatment with the Coldplay CryoBalloon Focal Ablation System…
The purpose of this study is to evaluate a new technique called Wide Area Transepithelial Sample 3-Dimensional Esophageal Biopsy (WATS) with computer assisted method of analysis of brush biopsy. This study will assess whether performing standard biopsies in addition to the WATS brush biopsies identifies more patients with dysplasia than does performing…
The purpose of the study is to compare two types of endoscopic treatments in patients with Barretts esophagus (BE) with abnormal cells (dysplasia); radiofrequency ablation (RFA) and hybrid argon plasma coagulation (H-APC). H-APC is a newer technique in the treatment of BE and has not been adequately studied and is not approved by the FDA for routine use.…
This study is for patients with Glaucoma. The purpose of this study is to investigate the safety and effectiveness of a study drug called Bimatoprost Sustained Release (SR) compared to treatment with eye drug Timolol. The Bimatoprost SR is an implant that is very small, is biodegradable (dissolves naturally in the body), and contains the bimatoprost drug.
Glaucoma is the leading cause of irreversible blindness worldwide. The most important test to detect progression is visual field testing. However, this test is very subjective, often unreliable, and variable. One of the main causes of unreliable tests is the lack of attentiveness or concentration during the test. Previous studies have shown that listening…
Glaucoma is a given name of a group of diseases that affect the retinal ganglion cells in the eye and the optic nerve. Glaucoma cause degeneration of the retinal ganglion cells in the retina and their projections (axons) that form the optic nerve. Retinal ganglion cells and their axons transmit all of our vision information from the eye to the brain through…
