Multicenter, Prospective, Randomized, Sham Controlled, Double Blinded Clinical Trial, with; 1:1 randomization

Sodium accumulates in the tissues of patients with kidney disease and impairs survival. Three-times weekly, standard hemodialysis alone cannot remove excess sodium efficiently. A sample of 10 chronic hemodialysis patients will undergo a 5-week, pilot, interventional study to test the efficacy of additional sodium removal in-between hemodialysis sessions, twice per week, for three weeks. Tissue sodium removal will be achieved with peritoneal dialysis after the surgical insertion of a peritoneal dialysis catheter. Tissue sodium removal will be assessed at the beginning and at the end of the study with sodium magnetic resonance imaging of a peripheral limb (leg). Patients will also undergo monitoring for symptoms and blood pressure throughout the study to assess the safety of this procedure.

The purpose of this study is to determine the feasibility of conducting a randomized controlled trial (RCT) with melatonin for treatment of delirium in critically ill adult patients. From a feasibility perspective, the investigators believe that the proposed design will achieve the minimum enrollment rate necessary to conduct a future RCT on a larger scale.

The purpose of this randomized controlled pilot trial is to test the effectiveness of a six-week tailored physical activity program with and without peer mentoring on the psychological constructs and exercise behaviour of inactive undergraduate women. The objectives are to: * Quantify the degree to which a peer-mentorship intervention affects exercise motivation determined through three basic psychological needs (i.e., autonomy, competence, and relatedness). * Examine general psychological distress and exercise engagement throughout the study. * Qualitatively explore participants' experiences following the completion of the program using an open-ended survey to gain a better understanding of its impact. Researchers will compare the parallel arm conditions to see how the inclusion of social support impacts exercise engagement. Participants will be asked to engage in exercise three times a week at the campus gym; those in the intervention condition will have an assigned peer-mentor who will join them for one weekly session and virtually communicate with them between sessions.

This is a randomized clinical trial comparing the outcomes of short-course chemoradiation consisting in stereotactic boost to the gross tumor and de-esclalated chemoradiation to the elective neck in human papilloma associated oropharynx cancer vs. the current standard 7-week course chemoradiation.

The purpose of this study is to describe the natural history and progression of patients diagnosed with PH1, and to characterize the long-term real-world safety and effectiveness of lumasiran.

The study aims at examining the impact of an immersive and interactive digital application (App) that uses impressionist artworks to promote the mental well-being of both young and older adults. The goal is to study the usability and accessibility of this App, particularly for older adults, who may have sensory impairments and lower digital literacy compared to younger adults. The study is based on the hypothesis that the App, which allows interaction with paintings by Claude Monet and Helen McNicoll, can trigger positive emotions, thereby improving users' well-being. The App uses artificial intelligence to create extensions of the paintings and music based on the sonification of electrophysiological signals captured from plants. The study seeks to answer four research questions: 1. The usage behaviors of young and older adults with the App. 2. The impressions and feedback from users after testing the App. 3. The obstacles and enablers to the App's use. 4. The expectations and needs of users for better use of the App. The study's objectives include analyzing the usage behaviors, impressions, barriers, and needs of both young and older adults. It is a qualitative study based on non-participatory observations and semi-structured interviews with young and older participants who have used the App. The App is based on impressionist artworks, a style known for evoking positive emotions, and aims to promote mental health by harnessing the emotional power of digital art and artificial intelligence.

Antiretroviral therapy or ART blocks HIV replication reducing plasma viral loads to undetectable levels but has no effect on persistently infected cells in the body, called the virus reservoir. These cells carry infectious HIV capable of restarting HIV replication if therapy is stopped. The reservoir is so stable forcing people to adhere life-long ART. Over 5% of ART adherent individuals continue to have residual non-suppressive viremia (NSV) detected by clinical assays (40-400 copies/ml). Residual viremia reflects a more persistent reservoir and has the potential for increased morbidity. For eg., persistent expression of HIV proteins contributes to inflammation, and can lead to comorbidities. Recently, a novel way to target this reservoir called "TACK" or "Targeted activator of cell killing" is proposed. TACK compounds only target HIV infected cells and directly kill them by inducing a natural killing program (called the inflammasome). Recently the HIV drug, Efavirenz (EFV), which was used to suppress HIV replication for decades, has now been shown to also be a TACK compound. This pilot study will evaluate the impact of Efavirenz (EFV) in reducing HIV persistence by its ability to be a TACK molecule. So in addition to blocking HIV growth, this compound when added to a current ART regimen can kill HIV infected cells in the test tube. We aim to harness this effect to determine whether the addition of EFV to the current ART regimen in people with NSV can suppress the viremia to undetectable levels by killing those cells. NSV represents the "the tip of the iceberg" of those with bigger reservoirs and represents a challenging clinical scenario in dire need of new diagnostic and therapeutic options. This pilot study will spark larger clinical trials to advance HIV cure strategies, and will provide new tools to improve the clinical management of people living with HIV.

Patients with chronic kidney disease receiving hemodialysis (HD) suffer from higher rates of brain vascular disease and decreased cognition than the general population. One way to assess brain vascular health and response to HD stress, is to test how the brain's blood flow responds to carbon dioxide (CO2) to measure Cerebrovascular Reactivity (CVR). In this study, the investigators will compare the magnitude and speed of the brain's blood flow response to a step-wise change in CO2 with hemodynamic, dialysis, and cognitive parameters. The goal of the study is to establish therapeutic targets that can be altered during the dialysis procedure to protect the brain from HD stress.

The corticomedullary gradient is largely responsible for developing the gradients that are needed to concentrate urine (more solutes and less water). The ability of the kidneys to produce concentrated urine is a major determinant of the ability to survive the warm weather. When temperatures are high, we lose water through sweat, and so the kidneys retain water to maintain fluidity in the blood. The maintenance of a sodium (salt) gradient is required for urine concentration because increased medullary sodium concentration increases the reabsorption of water into the kidney, to be redistributed in the blood. The purpose of this study is to know if the corticomedullary gradient is altered in patients across a wide spectrum of kidney disease using sodium Magnetic Resonance Imaging (MRI), a machine that takes pictures and measures the salt content in the kidneys. 23Na kidney MRI, will provide functional MR of the kidney as a non-invasive tool to describe medullary function to improve management of chronic and kidney disease.
