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…
Are you undergoing a stem cell transplant? You may be at high risk for infections after the transplant. This study is looking at the safety and effectiveness of an investigational medication for those who have undergone a stem cell transplant. Recovery after a stem cell transplant can already be challenging without the added worry of life-threatening viral…
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 see whether or not the medicine, Abatacept, when given after hematopoietic stem cell transplantation (HSCT) is effective in treating GVHD in children and adolescents with sickle cell disease (SCD). We are also planning to gather additional information about the safety of treating sickle cell disease with a hematopoietic stem…
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 main purpose of the study is to find out about whether the study drug is safe in humans and aneffective treatment in pediatric patients with acute Graft versus Host Disease (GVHD). GVHD mayoccur after a bone marrow or stem cell transplant in which someone receives bone marrow tissue orcells from a donor (called an allogeneic transplant). The new,…
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.…
In this trial, we will evaluate whether partially-HLA matched allogeneic multivirus-specific VSTs, will be safe and produce anti-viral effects in immunodeficient recipients infected with one of more of the targeted viruses that are persistent despite conventional anti-viral therapy. This will be in patients who have received a hematopoietic stem cell…
The primary objectives of this study are to measure the safety and effectiveness of bone marrow transplant (BMT) using specific chemotherapy in children with less severe SCD and to understand the long term effects of bone marrow transplant in children with SCD, by evaluating ovarian reserve, sickle cell related brain problems, sickle cell related kidney…
The purpose of this study is to test a new medicine to prevent liver venoocclusive disease (VOD) in patients undergoing hematopoietic stem cell transplant (HSCT) who are at high risk or very high risk for liver VOD following HSCT. Liver VOD can be a complication of bone marrow and/or stem cell transplant,which may be life threatening. The condition is a…
