The purpose of our research study is to increase our understanding on the human lung immune response to infection. We aim to use this knowledge to develop novel approaches on the prevention and treatment of lung infections. To accomplish this, we plan to obtain cells from the airways and blood of healthy volunteers to perform immune experiments.

The clear layer at the front of the eye that covers the pupil and iris (colored part of the eye) is called the “cornea”. When the cornea is damaged, it normally heals within a few days but it may take up to 2 weeks depending on the size and depth of the defect (wound). Some corneal defects heal much slower than expected. A defect in the cornea that fails to heal within the normal time of 2 weeks despite using the best available medicines and procedures, is known as Persistent Corneal Epithelial Defect (or PCED for short). The purpose of this research study is to evaluate the safety, tolerability, and effectiveness (risks and benefits) of of NEXAGON ophthalmic gel for the treatment of PCEDs.

We are investigating how paired non-invasive electrical stimulation of surface body regions and sound changes sound perception and tinnitus. Body stimulation regions include: external ear/behind the ear, shoulder, neck, forearm, hand, and upper arm. We aim to better understand the optimal conditions of this paired stimulation, which opens opportunities for applying this method to improving hearing loss or tinnitus. We are studying three groups of people: those with normal hearing, those with mild to moderate hearing loss, and those with tinnitus.

This research is being performed to examine how the spleen moves during breathing in various body positions and breathing conditions. Physical measurements of the participant's body will be recorded (weight, height, and body dimensions) and then noninvasive recordings of the spleen and breathing patterns will be recorded. The spleen motion will be measured using standard abdominal ultrasound imaging, and breathing will be measured with accelerometers (small devices about the size of a quarter that measure the movement of the chest during breathing).

In this study, we are comparing two different numbing techniques performed by anesthesiologists. Patients in the study are randomly selected to receive one or the other type of numbing injection. One group of patients will receive an epidural, which is a numbing injection done in the back, similar to that which women receive when they give birth. The other group of patients will receive a rectus sheath block, which is a numbing injection done on the abdomen. Both of these types of numbing injections are performed regularly by our anesthesiologists at the University.

XTMAB-16 is a new, experimental drug and is part of a group of drugs known as tumor necrosis factor alpha (TNF α) inhibitors. TNF is a protein in your body that causes inflammation. TNF α inhibitors work by suppressing part of the immune response along with reducing inflammation. We are conducting this research study to see if XTMAB-16 will help in the treatment of pulmonary sarcoidosis.

Primary Immune Regulatory Disorders (PIRD disorders) are a group of diseases that cause the immune system to function abnormally and cause infections, autoimmunity or inflammation that can begin early in life. PIRD is usually caused by changes in genes in DNA. Researchers are trying to learn what types of medical problems patients with PIRD have and how these respond to treatment. Researchers also want to learn which genes cause PIRD and how it can cause the medical problems of PIRD.

The goal of this study is to design wearable, comfortable sensors to measure muscle movement during tics. Small, flexible EMG sensors (the size of the head of a pin) will be embedded in a “band-aid like” plastic sticker which is placed on the side of the face. Participants will be video recorded as they complete movement tasks. The entire visit will take approximately 2 hours.

CGD disorders are a group of diseases that cause the immune system to function abnormally, leading to infections, autoimmunity and/or inflammation that can begin early in life. CGD is usually caused by changes in certain genes in DNA. Researchers are trying to learn what types of medical problems patients with CGD have and how these respond to treatment, including bone marrow transplantation and gene therapy. Researchers also want to learn which genes cause CGD and how specific gene abnormalities lead to medical problems.

This study is being done to better understand how the brain and impulsive decision-making are connected to depression and suicidal behaviors in people ages 13-21. Participants will complete clinical assessments, behavioral measures, undergo an MRI scan and complete transcranial magnetic stimulation with electroencephalography (TMS-EEG). There will be follow-ups at 6 and 12 months.

This research is being done to study binge eating and potential treatment strategies. An app on a sensor logging device will log eating behavior data. The device will incorporate data and refine the performance of the HabitAware sensor logging model to recognize binge eating episodes. We hope this research will help inform novel treatments for targeting binge eating behavior.

The primary study objective is to determine whether “Take on Transplant” (ToT), a CF-specific Lung Transplant (LTx) educational website, improves patient-reported preparedness for LTx discussions, as measured by the Preparation for Decision Making (PrepDM) Scale at 3 months after randomization, compared to an attention control transplant website (unos.org, UNOS).

This retrospective, longitudinal project is to collect certain demographic and clinical health status information for entry into the CF Foundation Patient Registry (also known as PortCF). The registry has played an important role in CF research and will continue to do so. In addition, much of the same information is entered into the University of Minnesota Cystic Fibrosis Center Research Database. This patient database has been maintained since 1975.

The purpose of this open-label Expanded Access Protocol (EAP) is to provide access to MBP134, for treatment of Sudan Virus Disease (SVD). Patients will receive a single IV infusion of 50 mg/kg MBP134. Patients will be monitored and assessed daily through discharge for safety and the incidence of serious adverse events (SAEs), and of all adverse events (AEs) during infusions.

The purpose of this study is to find out if using a computer program (called iDose) to guide infliximab dosing is more effective and safer than using standard infliximab dosing over 52 weeks. All patients in this study will be receiving infliximab as part of their medical care, this study is only looking at two different methods of determining the dose and timing of administration.

We want to explore whether it is possible for adults without symptoms of heart disease to perform a short, high intensity exercise routine in a clinic setting in order to measure maximum heart rate and heart rate recovery. If this method is successful, it could be used by patients and clinicians to estimate and track heart health over time.

This research is being done to assess whether it is safe and effective to stop oral anticoagulation medications (a blood-thinning medication) during prolonged periods of normal heart rhythm in participants with infrequent episodes of atrial fibrillation (AF).

This study will use BBP-418 study drug in patients with LGMD to assess the clinical biomarkers, efficacy and safety of BBP-418 during the 36 months treatment phase.

Amblyopia (sometimes called 'lazy eye') is reduced vision in one eye caused by abnormal visual development early in life. The weaker (or 'lazy') eye often wanders inward and outward. Amblyopia is the leading cause of reduced vision in children and can lead to blindness if not treated. Treatments for amblyopia are glasses, and if needed, further treatment with part-time patching or penalization with atropine eye drops. Patching or atropine are administered to the stronger eye to force the child to use the weaker (amblyopic) eye. In recent years, an alternative type of therapy has emerged. It is called dichoptic treatment and involves stimulating both eyes simultaneously but with different stimuli. When it was first introduced, it was done in an office-based setting. Home-based technologies utilizing games and movies have been developed and studied to a limited extent in younger children with amblyopia. In this study, we will use a system called Luminopia. It uses a virtual reality headset to view web-based videos in which the contrast of the image seen by the stronger eye is reduced by 15% from that of the weaker eye. Luminopia has been available for use in the U.S. since 2022 and has been approved by the FDA for the treatment of amblyopia in this age group. In a previous large randomized trial, home-based dichoptic movies were shown to be superior to glasses alone but treatment effectiveness compared to patching (the gold standard for treating amblyopia) has not yet been established. If dichoptic therapy using the Luminopia system is confirmed to be at least as effective as patching, it would be an appealing alternative for treating amblyopia in young children, as it shows promise of better adherence and an easier treatment experience for the parent and the child. Children in this study would be randomized 1:1 to either the Patching Group or the Luminopia Group and followed for at least 6 months. Children in the Patching Group will have the option to do the Luminopia treatment after 6 months of patching. They will be followed for an additional 6 months. Thus, their participation will last for a total of 1 year.

Skytrofa is approved in the U.S. for sale and use in children with growth hormone deficiency (GHD). This study is being done to find out how safe and useful Skytrofa is for long-term treatment. A child’s care will follow the normal treatment practices at the clinic. There is no new treatment or medicine involved and no additional visits will be performed.

This project is a data and specimen repository for developmental disorders. Participants provide biological samples and permission to store their health-related data. The purpose is collect and manage these materials for use in biomedical research related to developmental disorders.

The purpose of this research is to better understand how deep brain stimulation settings can affect the electrical activity in the brain and the frequency of seizures. There are a number of different ways in which the deep brain stimulation electrodes can be programmed to stimulate the brain. This research study uses the implanted battery in the chest to record electrical activity from the brain at different stimulation settings. We then use this electrical activity to determine stimulation settings that are “personalized” to your brain.

The purpose of this research is to learn if home use of high flow nasal therapy (HFNT) increases the time to rehospitalization for people with chronic obstructive pulmonary disease (COPD). Participants will be randomly (by chance; like the flip of a coin) assigned to one of two groups. One group will receive usual medical care for COPD. The other group will receive usual medical care for COPD and use a high-flow nasal therapy device for a minimum of 8 hours daily. Participants will complete daily COPD symptom reports. This research will last for at least 12 months and up to 24 months.

The purpose of the study is to test new biomarkers of ALS using MRI scans at 3 Tesla (3T). A biomarker is a measurable characteristic that can be used as an indicator of a particular disease state. Identifying biomarkers in ALS will help test new treatments and may help us make diagnoses earlier.

The objective of this study is to evaluate the safety and feasibility of implantation of the Aria CV PH System in subjects with pulmonary hypertension (PH) and right heart dysfunction. In addition, the study will evaluate early signals of performance of the implanted system.

We are doing this study to see if we can improve the standard treatment for OCD, Exposure with Response Prevention, by pairing it with Transcranial Magnetic Stimulation to the parts of the brain that cause OCD symptoms.

The purpose of the study is to see how restricting the eating window (called time-restricted eating) might affect eating habits, weight, and blood measures compared to reducing food intake. Time-restricted eating means that people would have a daily 8 hour eating window during which time they can eat whatever they want. Outside of the eating window, people would only take water and your medications. We expect that participants will be in this research study for about 7 months.

This study explores the associations between maternal stress, breastmilk composition, and feeding and neurodevelopment for preterm infants in the NICU and at 4 months corrected age.

The goal of this study is to better understand how drinking alcohol may lead to oral cancers. Acetaldehyde, a chemical formed when the body breaks down alcohol, is believed to play an important role. This study will measure acetaldehyde and DNA damage levels in the mouth of participants after a low dose of alcohol. The levels will be compared between three groups, all having different degrees of risk for developing oral cancer, and with non-drinkers to identify DNA damage that might be important to cancer formation. We also want to understand how alcohol can affect the bacteria in our mouths and how that might impact oral DNA damage.
