The purpose of this research study is to assess whether morning bright light therapy using a wearable glasses device called a Re-Timer could potentially improve Irritable Bowel Syndrome (IBS) symptoms and decrease intestinal permeability (leaky gut). Morning bright therapy will be administrated through a safe-wearable device called a Re-Timer. The Re-Timer glasses are lightweight and deliver blue-green light at 500nm, mimicking exposure to natural light.

The primary aim is to construct individualized treatment rule (ITR) models that predict optimal medication selection for deprescribing to maximize potential benefits and reduce harms to patients. To address this aim, we will collect retrospective EHR data for individuals over age 65 from three participating sites (Duke, Vanderbilt, and Medical University of South Carolina) and link this with medication dispensing and insurance claims data from the Centers for Medicare and Medicaid Services(CMS). We will apply causal inference methodology and supervised and unsupervised machine learning algorithms to predict both the benefits (reduced falls, cognitive disorders, hospitalizations) and potential
harms (adverse drug withdrawal events) of medication discontinuation. These predictions will be specific to individual patients and various central nervous system (CNS)-acting medication classes. The resulting machine learning models will be integrated into ITR models which will, in turn, support clinical practice by
recommending the medication class most likely to provide benefits, factoring in individual patient characteristics.

This study is for adult patients with head and neck cancer who are at risk of recurrence. The purpose of this study is to evaluate whether the use of Indocyanine Green (ICG) dye allows for better identification of tumor tissue during surgical procedures. Participation will include standard of care visits along with administration of ICG dye and imaging during surgery. Participation in this study will last approximately 6 weeks.

The purpose of this study is to test the safety of NXC-201 at different doses in participants with relapsed/refractory AL amyloidosis, and to confirm the best dose for further testing. In addition, the study will evaluate the effectiveness of NXC-201 in treating relapsed/refractory AL amyloidosis.

AL amyloidosis is a rare systemic disorder caused by an abnormality of plasma cells (a type of white blood cell that is part of the immune system) in the bone marrow. Misfolded proteins produced by these cells can build up in and around tissues, nerves and organs, gradually affecting their function. This can cause progressive and widespread organ damage.

NXC-201 is made using a person's own T Cells (immune system cells that protect the body from infections, cancer, and other possible harms). The T cells are collected then genetically modified (changes are made to the DNA or genes) outside of the body in a laboratory. A virus is used to introduce a gene that creates a protein (called a chimeric antigen receptor or CAR) on the surface of T cells. The virus then becomes inactive. The changes are designed to help the NXC-201 cells find and destroy plasma cells that have a protein on their surface called B-cell maturation antigen (BCMA). T-cell therapies like NXC-201 are called CAR T-cell therapies. After being reinjected, the CAR-T cells multiply and spread throughout the body.

NXC-201 is an investigational "treatment", which means it has not been approved by the US Food and Drug Administration (FDA) for the treatment of AL Amyloidosis or any other disease.

Calling the study drug a "treatment" in this consent form does not indicate that it will be effective in treating your AL Amyloidosis.

Before receiving NXC-201, participants will receive lymphodepleting chemotherapy (or lymphodepletion) with cyclophosphamide and fludarabine to briefly weaken (suppress) your immune system. The lymphodepletion will help prepare the body for receiving NXC-201. Cyclophosphamide and fludarabine are FDA-approved for use as lymphodepleting chemotherapy.
