Alpelisib Challenge Test (ACT)

Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are recruiting volunteers, aged 18-70 without diabetes, for a research study on determining how much of the blood sugar- lowering hormone insulin the body can produce in order to better identify people at risk for diabetes in the future. To do this, we will have approximately 15 participants stay for approximately 30 hours (including overnight) in the…

Understanding Flavor: How Smell Shapes What We Taste

Condition: Ear, Nose and Throat / Loss of Smell
Investigator: Jonathan Overdevest, MD, PhD
Status: Currently Recruiting
The Columbia University Department of Otolaryngology is interested in understanding altered flavor perception through the Cognitive Flavor Assessment Protocol (CFAP), a novel multisensory diagnostic and training framework that links smell and taste function to cognitive and emotional health. You can participate in this study if you are an adult between 18…

Lowering Insulin to Decrease Liver Fat Production

Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are conducting a research study on the effect of high insulin levels on the buildup of excessive liver fat ("fatty liver disease") in people at risk for type 2 diabetes. We are seeking adult volunteers, ages 18-65, who have obesity with a body mass index of 30-45, and have been diagnosed with, or are at risk for, prediabetes and metabolic…

Prescribed or recommended tirzepatide? Participate in a Study on Brain Activity and Decision-Making

Condition: Obesity
Investigator: Daphna Shohamy, PhD
Status: Currently Recruiting
We are researchers at Columbia studying the learning and decision making. We are looking for participants over the age of 18, who have been prescribed Trizepatide for weight loss. Participants will be asked to complete an MRI scan and play computer games. Participants earn $25 per hour. Help us understand how the GLP-1 agonists affect brain and cognition!

POWERS - Understanding Body Changes After Weight Loss

Condition: Obesity
Investigator: Rudolph Leibel, MD
Status: Currently Recruiting
The Physiology of the Weight Reduced State (POWERS) is a national research study designed to discover and learn what happens to the human body after weight loss and to learn why some people regain their lost weight. Understanding why this happens could help health professionals improve strategies for successful weight loss maintenance after weight loss.…

Weight Loss Study: Genetic Variations and Response to Naltrexone/Bupropion

Condition: Obesity
Investigator: Judith Korner, MD
Status: Currently Recruiting
The purpose of this study is to evaluate if genetic variations are associated with the amount of weight loss with diet and while taking an FDA-approved medication for weight loss. The participation lasts ten months and includes six in-person visits at CUIMC with blood sampling and questionnaires, virtual nutritional counseling, and taking an oral weight…

Early Age-Related Hearing Loss Investigation (EARHLI)

Condition: Ear, Nose and Throat / Hearing Loss
Investigator: Justin Golub, MD, MS
Status: Currently Recruiting
Early Age-Related Hearing Loss Investigation (EARHLI) is a study to obtain information on how a hearing aid-based intervention can prevent cognitive decline in those at risk for Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD). Age-related hearing loss (ARHL) is the third most common chronic condition in older adults. The…

Metabolic Effects of Hypoglossal Nerve Stimulation (Inspire)

Condition: Ear, Nose and Throat
Investigator: Yi Cai, Md
Status: Currently Recruiting
We are currently looking for adult patients who have undergone successful treatment of their obstructive sleep apnea with a hypoglossal nerve stimulator implant (i.e. Inspire therapy). Participants should be willing to participate in at-home sleep studies and come to Columbia University Irving Medical Center for at least 2 study visits. Participants will…

Does Your Nose Remember? Understanding the Role of Smell in Memory Processes (ENT)

Condition: Ear, Nose and Throat
Investigator: Jonathan Overdevest, MD, PhD
Status: Currently Recruiting
The Columbia Otolaryngology Department is interested in understanding how sense of smell relates to memory and neurocognition. Participation will involve answering a series of questionnaires, completing a formal evaluation of your smell with standardized measurements, and complete short smell and memory games. You can participate in this study if you are…

Temporary Insulin Resistance

Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are recruiting volunteers, aged 18-70, for a research study on the buildup of excessive liver fat ("fatty liver disease") in people with or at risk for type 2 diabetes because their bodies are resistant to the actions of the blood sugar-lowering hormone, insulin. To do this, we seek to temporarily induce or accentuate insulin resistance in 14…

Biobank of Blood Samples from Overweight or Obese Patients

Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are seeking adult volunteers with body mass index in the obesity range (30-45 kg/m2) to come in for a single study visit where they answer some health questions and have a small volume of blood drawn (25 cc/1.7 tbsp). We will measure levels of the blood sugar-lowering hormone insulin as well as glucose (sugar), certain fats, and other molecules related…

Smelling the Juice: Functional Smell and Taste Preferences in Vaping and Cigarette Smoking

Condition: Ear, Nose and Throat
Investigator: Jonathan Overdevest, MD, PhD
Status: Currently Recruiting
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…

Speech Perception in Hearing Impaired Listeners

Condition: Ear, Nose and Throat / Hearing Loss
Investigator: Nima Mesgarani, PhD
Status: Currently Recruiting
The purpose of this study is to learn more about the mechanisms of hearing loss, specifically to learn how abnormalities in the brain may produce certain experiences that are common in patients with hearing loss. Individuals with hearing loss will be compared to individuals with normal hearing.
