This phase II trial studies how well lower-dose chemotherapy plus radiation (chemoradiation) therapy works in comparison to standard-dose chemoradiation in treating patients with early-stage anal cancer. Drugs used in chemotherapy, such as mitomycin, fluorouracil, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving chemotherapy with radiation therapy may kill more tumor cells. This study may help doctors find out if lower-dose chemoradiation is as effective and has fewer side effects than standard-dose chemoradiation, which is the usual approach for treatment of this cancer type.

The purpose of this observational study is to find the best measures to define how well a person with eosinophilic disorder is doing. People with EoE, EoG, EoN and EoC normally undergo endoscopy and/or colonoscopy where cells are collected for microscopic analysis. Treatments are then decided based on how the cells look. We are aiming to compare different tissue components such as inflammatory cell types with clinical symptoms. We want to see if scores on standard questionnaires can give us an idea how well the person is doing.

This phase IV trial evaluates how well giving standard of care (SOC) peptide receptor radionuclide therapy (PRRT) after SOC surgical removal of as much tumor as possible (debulking surgery) works in treating patients with grade 1 or 2, somatostatin receptor (SSTR) positive, gastroenteropancreatic neuroendocrine tumors (GEP-NETs) that have spread from where they first started (primary site) to the liver (hepatic metastasis). Lutetium Lu 177 dotatate is a radioactive drug that uses targeted radiation to kill tumor cells. Lutetium Lu 177 dotatate includes a radioactive form (an isotope) of the element called lutetium. This radioactive isotope (Lu-177) is attached to a molecule called dotatate. On the surface of GEP-NET tumor cells, a receptor called a somatostatin receptor binds to dotatate. When this binding occurs, the lutetium Lu 177 dotatate drug then enters somatostatin receptor-positive tumor cells, and radiation emitted by Lu-177 helps kill the cells. Giving lutetium Lu 177 dotatate after surgical debulking may better treat patients with grade 1/2 GEP-NETs

Among critically ill adults undergoing emergency tracheal intubation, one in five experience hypotension, cardiac arrest, or death. The sedatives used to rapidly induce anesthesia for emergency tracheal intubation have been hypothesized to effect cardiovascular complications and patient outcomes, but the optimal sedative medication for intubation of critically ill adults remains unknown. Ketamine and etomidate are the two most commonly used sedatives during intubation of critically ill adults. Data from a randomized clinical trial are urgently needed to determine the effect of ketamine versus etomidate on cardiovascular complications and clinical outcomes of emergency tracheal intubation.

This study will use an observational cohort to cross-sectionally and longitudinally relate vascular health to clinical, imaging, and biological markers of early Alzheimer's disease and cerebrovascular disease among aging adults. Adjusting for relevant clinical covariates, we will test the hypothesis that vascular health is associated with clinical, brain magnetic resonance imaging (MRI), neuropsychological, and cerebrospinal fluid markers of early cerebrovascular and Alzheimer's disease changes (i.e., prior to the onset of significant cognitive decline or dementia). Secondarily, we will examine medical and genetic factors that might mediate associations between vascular health and brain aging, such as inflammatory processes, insulin resistance, and genetic factors (e.g., APOE, a susceptibility risk factor for dementia). Findings will advance knowledge regarding the role that vascular health plays in brain aging.

The 2021 ACR RA treatment guideline, based on widely acknowledged low to moderate quality evidence, recommends switching to a non-tumor necrosis factor (TNFi) biologic (choose among existing medications, currently, rituximab, abatacept, tocilizumab, or sarilumab) or a targeted synthetic DMARD arm (tsDMARD; choose among existing medications, currently, tofacitinib, baricitinib, upadacitinib) in patients with active RA despite the use of a TNFi-biologic. In practice, most patients receive another TNFi-biologic, i.e., a second TNFi-biologic first. This is not based on solid evidence, but on arbitrary algorithms often proposed by health insurance plans, and/or physician experience and habit (TNFis launched 22 yrs ago vs. the first tsDMARD 8 years ago vs. first non-TNF-biologic launched 17 years ago). This study will fill a critical knowledge gap by generating CER data for important PROs between these treatment options, switching to a non-TNFi biologic or a tsDMARD in patients with active RA despite the use of a TNFi-biologic.

Persons with human immunodeficiency virus (HIV) have higher risk of developing fatty liver disease (NAFLD) than HIV-negative persons but the reasons for this discrepancy are not known. Changes in the intestinal microbiome may contribute to the development of NAFLD in persons with HIV (PWH) through impairment of barrier function of the intestinal wall and by producing metabolites that are harmful to the liver. This project will test the hypothesis that HIV-related NAFLD is associated with differences in the intestinal microbiome and that supplementation with probiotic and prebiotic fiber will lead to improvements in markers of NAFLD in PWH.

This phase II trial tests whether adding nivolumab to the usual treatment (encorafenib and cetuximab) works better than the usual treatment alone to shrink tumors in patients with colorectal cancer that has spread to other places in the body (metastatic) or that cannot be removed by surgery (unresectable) and whose tumor has a mutation in a gene called BRAF. Encorafenib is in a class of medications called kinase inhibitors. It is used in patients whose cancer has a certain mutation (change) in the BRAF gene. It works by blocking the action of mutated BRAF that signals cancer cells to multiply. This helps to stop or slow the spread of cancer cells. Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of cancer cells. This may help keep cancer cells from growing. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving nivolumab in combination with encorafenib and cetuximab may be more effective than encorafenib and cetuximab alone at stopping tumor growth and spreading in patients with metastatic or unresectable BRAF-mutant colorectal cancer.
