The investigators performing this research to study if routine flushing is necessary to prevent obstructions of a nephrostomy tube. This study will evaluate patients that have nephrostomy tube or will have nephrostomy tubes placed as part of their standard clinical care. If participants agree to participate in this study, participants will undergo randomized assignment to either continue to routinely flush the nephrostomy tube with normal saline or not to routinely flush the nephrostomy tube with normal saline. Participantswill be in the study for approximately 3 months if they decide to stay for the whole study.

The investigators will conduct a 3-arm, pilot RCT where participants (N=30) will be randomized in a 1:1:1 design to 4 weeks of instructed bedtime MM practice at night (n=10) vs. uninstructed MM (n=10) vs. sleep hygiene education only (n=10). Aim 1 is to understand the feasibility and acceptability of the intervention and study procedures. Aim 2 is to explore patterns of within-group changes in sleep outcomes (i.e., insomnia severity and sleep quality). Patient-reported outcomes will be collected using a HIPAA-compliant electronic data management system (REDCap). Following informed consent, participants will receive links to REDCap surveys via email at Weeks 0, 4, 8, and 16. The investigators will also conduct a post-intervention interview at the end of Week 4 and an exit interview at Week 16. All participants will also receive a research kit with wearable devices and meet with our staff after they receive the kit for instructions. Data collected in the pilot RCT will help us to preliminarily identify tools for subjective measures and physiological signals to inform a future trial.

Investigators aim to conduct a type 1 hybrid effectiveness-implementation surgeon-level cluster randomized clinical trial (RCT) of a multi-level intervention, a shared decision making training for surgeons plus patient decision aid vs. usual care (UC), at 7 large health systems across the U.S. to learn the intervention's effectiveness. Decision aids will be mailed and sent via patient portal and/or via email (when portal/email addresses are available) to patients before their first surgical encounter. The central hypothesis is that the novel intervention will be a key resource to support shared decision making leading to higher quality treatment decisions and as result improved care and outcomes.

Pancreatic necrosis is a serious complication of acute pancreatitis. Pancreatic necrosis involves the irreversible death of pancreatic tissue, which can lead to severe health issues, including infections and an increased risk of death. An endoscopic procedure called direct endoscopic necrosectomy (DEN) is typically performed to remove this necrotic pancreatic tissue as a minimally invasive treatment. This procedure is performed using a thin, flexible, lighted tube called an endoscope and endoscopic instruments that are used with working channels through the scope. Current methods for removing necrotic tissue involve using endoscopic devices such as snares, baskets, nets, and forceps. However, these standard methods are often not very effective because the necrotic tissue can be sticky and hard to grasp. This DEN procedure is part of regular clinical care to treat this condition and remove necrotic tissue from the pancreas. For this research study, the same DEN procedure will be followed with the exception of the device used for the removal of the necrotic tissue. Instead of using forceps, snares, or other traditional tools, a cryoprobe will be used. Cryoprobes work by using extremely cold temperatures to freeze and adhere to the necrotic tissue, making it easier to remove. This method might be better because it can secure larger tissue samples and potentially reduce complications associated with traditional methods. Cryotechnology is successfully used in endoscopy to remove necrotic tissue, foreign bodies and more, but has not been extensively tested in pancreatic necrosis. Cryoprobes are FDA approved medical devices with an established safety record. They are used successfully in very sensitive areas such as the lungs. This study aims to evaluate the safety and effectiveness of cryotechnology for DEN.

This phase 2a study will research the safety and tolerability of Foralumab, a human anti-CD3 antibody. An antibody is a molecule secreted by the immune system. These molecules are created to identify a specific pathogen. Previous data on experimental mice has suggested that Foralumab increases the immune system activity in the brain to reduce the inflammation of microglia, the brain's main immune cells. This combination of increased immune reactivity and less microglia inflammation may improve the immune response throughout the brain. Alzheimer's disease and other forms of dementia are characteristically known for the build-up of certain proteins in the brain. This trial will evaluate whether nasal Foralumab can improve cognition in participants with mild cognitive impairment due to early Alzheimer's or dementia. The trial will ask participants to administer Foralumab nasally three times a week for eight weeks. The administration will occur intermittently, with breaks between each dosing cycle. Participants will also receive brain scans (Amyloid PET and MRI), undergo cognitive testing, blood draws, and physical, neurological, and nasal exams. Volunteers are expected to remain in the trial for six months.

Blood cancers occur when the molecules that control normal cell growth are damaged. Many of these changes can be detected by directly examining parts of the cancer or cells in blood. Several alterations that occur repeatedly in certain types of blood cancers have already been identified, and these discoveries have led to the development of new drugs that target those alterations. More remain to be discovered. Some of these abnormalities include alterations in genes. Genes are the part of cells that contain the instructions which tell the investigators bodies how to grow and work, and determine physical characteristics such as hair and eye color. Genes are composed of DNA letters that spell out these instructions. Studies of the DNA molecules that make up the genes are called "molecular" analyses. Molecular analyses are ways of reading the DNA letters to identify errors in genes that may contribute to an increased risk of cancer or to the behavior of the cancer cells. Some changes in genes occur only in cancer cells. Others occur in the genes that are passed from parent to child. This research study will examine both kinds of genes. The best way to find these genes is to study large numbers of people. The investigators expect that as many 1000 individuals will enroll in this study. This research study is trying to help doctors and scientists understand why cancer occurs and to develop ways to better treat and prevent it. To participate in this study the participant must have cancer now, had it in the past, or are at risk of developing cancer. The participant will not undergo tests or procedures that are not required as part of their routine clinical care. The investigators will ask the participant to provide an additional sample from tissue that is obtained for their clinical care including blood, bone marrow, or tissue sample. The investigators will also ask for a gentle scrape of the inside of their cheek, mouthwash or a skin sample to obtain their germline DNA

This study aims to assess the feasibility of magnetic resonance (MR) guided prostate biopsy using a needle holder frame. This frame is used to help position the needle used for the biopsy. The feasibility in this study is defined as whether the needle holder frame enables accurate tissue sampling from a suspicious region in the prostate found on an MR image. If it does, a biopsy can be carried out with the needle holder frame safely in a clinical routine. The study will be conducted during a routine MR-guided prostate biopsy procedure with an investigational needle holder frame instead of a conventional needle-guiding template.
