Cochlear Implantation often results in loss of any remaining hearing that may have been present prior to the surgery and the patient uses only the cochlear implant to hear. Saving the remaining hearing is important because it can allow a recipient to also utilize a hearing aid in that ear in addition to the cochlear implant, termed electro-acoustic stimulation. Thus, the goals of this study are: 1) to determine the importance of electrocochleography in helping to save remaining hearing during the surgical procedure, 2) determine the benefit that a hearing aid and cochlear implant combination of listening impacts a patient's ability to understand speech compared to the traditional condition of using the cochlear implant alone without a hearing aid.

We would like to better understand what adverse symptoms occur after cardiac surgery and intensive care and how symptoms evolve over time. We will be following patients' symptoms from prior to their surgery to three months after ICU discharge.

This study wants to test a inhaled version of an already approved medication for pulmonary hypertension (PH). The purpose is to test its safety and tolerability in group 1 and group 3 PH patients.

I will conduct focus groups with Venezuelan migrants in Colombia to see the effects of gender on migrants' access to state services like public schools and the police.

This study aims to develop a blood test to track, locate, and diagnose aortic aneurysm disease.

The purpose of this study is to understand how your gut plays a role in how well CAR T cell therapy works. Your gut is home to bacteria, which we call the gut microbiome. The gut microbiome can send signals to your immune cells, which may impact how well and how long CAR T cell therapy will last. We can find out what type of bacteria are in your gut microbiome by studying your stool. We can understand more about the signals sent to the immune system by studying your blood. We will ask for stool and blood at the same time points throughout your treatment. We will study the identities and function of the bacteria and immune cells to understand more about how these signals work during CAR T cell treatment.

We are surveying families of pediatric hematology/oncology patients to find out their interest in and use of integrative and complementary health practices.

This study compares two dose strengths of a new epilepsy medicine to placebo for treatment of refractory focal onset epilepsy as measured by the change in 28-day average seizure frequency.

We intend to study sensations generated by spinal cord stimulation with the goal of using this knowledge to develop electrical interfaces that can restore loss of sensory function after neurological injury or disease.
