All Clinical Trials

The goal of this clinical trial is to compare the onset and duration of numbness of the surface of the eye following the administration of numbing drops, called proparacaine, using either a standard eye drop bottle or a "Nanodropper" adaptor. The Nanodropper is designed to administer smaller-sized drops, or microdrops. Participants will: 1. Complete a baseline eye exam. 2. Receive a numbing drop using a standard dropper in one eye and the Nanodropper in the other eye. 3. Have their eyes tested for numbness at specific time points (30 seconds, 1, 2, 5, and 10 minutes after getting the drops). 4. Tell the researchers if they feel pain during the eye sensation tests. 5. Complete a survey about their experience with the eyedrops and testing procedure. This study could help us find a way to use less medication while still effectively administering eye medications, potentially saving money and reducing medical waste. Read Less

Immediate lymphatic reconstruction (ILR) is a novel surgical approach performed at the time of initial lymph node dissection with the goal of preventing lymphedema. It involves the identification of lymphatic channels that are transected after lymph node dissection and microsurgical anastomosis of one or more lymphatic channel with a local recipient vein to re-direct upper extremity lymphatic drainage. Although ILR carries significant promise in prevention of lymphedema, there is a lack of high-level evidence supporting its efficacy because it is a novel surgical technique that is only offered at a few centers and not routinely covered by insurance carriers yet. The University of Chicago Comprehensive Cancer Center (UCCCC) is one of the busiest microsurgery centers performing this procedure, and, as a Lymphedema Center of Excellence, is in a unique position to investigate the efficacy of ILR in preventing lymphedema. In addition, the University has access to a world class microbiome research facility and colleagues. There is no information on the skin microbiome of the axilla in patients undergoing treatment for breast cancer or those at risk for developing lymphedema. Further exploratory studies such as this in a diverse patient population may lead to practice changing research in our approach to lymphedema management and prevention. The purpose of this study is to determine the role of immediate lymphatic reconstruction and obtain objective data to correlate the existing, self-reported rates of lymphedema at the University of Chicago.

This trial is designed to assess immunological biomarkers measured from blood samples that can be used to reliably predict how well vaccines work against symptomatic COVID-19 as well as to evaluate the feasibility of remote, self-collected specimens when conducting a correlates analysis. For a lot of research studies, people need to go to the study doctor's office regularly. For this study, we want to see if it is okay that people do the study doctor visits virtually, fill out questionnaires electronically, and collect their own samples remotely. Participants will enroll in the study after receiving a COVID-19 vaccine in their community, and saliva and blood specimens will be collected at pre-defined timepoints over a 12-month period. Additionally, participants will report weekly whether they experience symptoms of COVID-19, and if so, will be prompted to collect a nasal swab for testing. Most participants will complete all activities remotely and via electronic communications, but a small number will complete activities in person at the doctor's office to provide a comparison group. Samples from the study will be analyzed to determine whether the biomarkers can be measured, and data from the study will be used to evaluate the feasibility of doing the specimen and data collection without the participant going to the doctor's office in person.

Sudden cardiac death is a tragic event that strikes all age groups and is unfortunately increasing in prevalence. Because it is difficult to predict those at highest risk, this study is designed to test the hypothesis that new imaging techniques (magnetic resonance imaging \[MRI\] and computed tomography \[CT\]) are useful for identifying factors which put people at high risk for sudden death.

The purpose of this study is to determine how beta-glucan affects the immune system in subjects with non-small cell lung cancer. Read Less

The primary objective of the protocol is to develop a comprehensive specimen banking program from patients with lung cancer for future translation research, which will enable the investigators to detect lung cancer earlier, develop better therapies and explore screening and prevention strategies.

The purpose of this study is to examine whether cerebellar stimulation can be used to improve cognitive deficits and mood in patients with schizophrenia, autism, bipolar disorder, Parkinson's disease, and major depression. Read Less

This is a comparative study using resected/ biopsied tumors samples collected from renal cell carcinoma and urothelial carcinoma patients who underwent surgical removal of lesions, followed by immune checkpoint blockade (ICB) treatment targting programmed cell death 1 (PD1) but developed new lesions later were also removed and stored in the biosample repository (BSR). The histology and genomic analysis of the pre-treatment and metastatic samples from the same patient would be used to find out the changes that may have lead to metastasis. Also, metastatic samples from ICB naive patients would be collected and compared with those from ICB treated patients to find out if the metastasis in treated patients was due to development of reistance.

This research study is studying the combination of venetoclax and chemotherapy as a possible treatment for acute myelogenous leukemia (AML). The drugs involved in this study are: * Venetoclax * Daunorubicin * Cytarabine Read Less

The Principal Investigator's (PI) working hypothesis is that the PI can utilize the high predictive value of 18F-DCFPyl PSMA to identify clinically significant tumors in patients who will undergo brachytherapy, as well as areas which are uninvolved or contain only clinically insignificant disease. In the PI's clinical trial, the uninvolved regions (as defined by combined PET-MR-biopsy data) will not be targeted and receive only fall-off dose, which we have shown to be associated with reductions in toxicity.

The objective of this study is to better understand the comprehensive integration of both clinical and genetic factors that will help to identify mothers who could be at an increased risk of poor response to opioid substitution and infants at risk of significant neonatal abstinence syndrome (NAS).
