There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
In this study the investigators plan to enroll three groups of patients: non-Sjogren's dry eye, Sjogren's dry eye and controls. The study has the following primary goals: 1. To determine whether dry eye is associated with reduced corneal sensation 2. To determine whether reduced corneal sensation is due to the severity of the dry eye, the type of dry eye (primarily aqueous deficient versus primarily evaporative) or entirely related to the presence of Sjogren's 3. To determine whether corneal sensation is associated with ocular or systemic pain symptoms Additionally, the study aims to compare the novel corneal esthesiometer measurements to confocal biomicroscopy findings in determining neurotrophic keratitis (NK) and assess correlations between corneal sensation.
Background: Chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) are blood cancers that affect certain white blood cells. Advanced forms of these diseases are difficult to treat. CD19 is a protein often found on the surfaces of these cancer cells. Researchers can modify a person's own immune cells (T cells) to target CD19. When these modified T cells are returned to the body-a treatment called anti-CD19 chimeric antigen receptor (CAR) T cell therapy-they may help kill cancer cells. Objective: To test anti-CD19 CAR T cell therapy in people with CLL or SLL. Eligibility: People aged 18 years and older with CLL or SLL that has not been controlled with standard drugs. Design: Participants will be screened. They will have imaging scans and tests of their heart function. If a sample of tissue from their tumor is not available, a new one may be taken; the sample will be tested for CD19. Participants will receive a drug to reduce the leukemia cells in their blood. Then they will undergo apheresis: Blood will be taken from the body through a needle. The blood will pass through a machine that separates out the T cells. The remaining blood will be returned to the body through a different needle. The collected T cells will be gene edited to make them attack cells with CD19. Participants will take drugs to prepare them for treatment for 3 days. These drugs will start 5 days before the treatment. Then their own modified CAR T cells will be returned to their bloodstream. Participants will stay in the hospital for at least 9 days after the treatment. Follow-up visits will continue for 5 years.
The goal of this pilot clinical trial is to evaluate a culturally tailored computerized education program in hospitalized African-American patients with advanced chronic kidney disease (CKD). The main question it aims to answer are: does computerized adaptive education (CAE) increase patients' knowledge about CKD self-care and renal replacement therapy (RRT) options compared to usual care (UC) and will CAE will be increase patients' intent to participate in CKD self-care and RRT preparation compared to UC
The proposed study is a double-blind, randomized, placebo-controlled study of intranasal oxytocin (OXT) to determine its efficacy in improving quality of life and reducing stress in caregivers to persons with dementia. Planned enrollment is 32 participants over 2 years.
Compare the efficacy and safety between pulmonary vein isolation (PVI) alone versus PVI with left atrial (LA) posterior wall isolation (PWI) using pulsed-field ablation (PFA) in the treatment of patients with paroxysmal atrial fibrillation (PAF).
The research study will examine engagement in telehealth for children undergoing psychotherapy. The study in Phase I entails a pilot randomized trial with a goal to enroll 42 families, examining patient engagement in Teleo, a virtual therapy platform specifically designed for psychotherapy with youth, as compared to standard video conferencing. Engagement will be assessed using well-established measures - PRIME-O (modified) video coding, MTT-Y/MTTCG and attendance data (sessions 1-4). Clinicians in the study will deliver therapy to clients for 4 sessions, providing opportunity to measure temporal sustainment of any engagement differences.
This is a multicenter randomized controlled trial of 1100 patients to evaluate the superiority of combined intraoperative wound irrigation with intraoperative peritoneal lavage with dilute aqueous povidone-iodine compared to normal saline in male and female patients between the ages of 18 and 80 years old undergoing emergency laparotomies with Centers for Disease Control (CDC) class 2 and 3 wounds.
Roux-en-Y (RYGB) gastric bypass reduces the size and capacity of the stomach and bypasses a portion of the small intestine which leads to decreased food intake and higher levels of a gut hormone called GLP-1 (glucagon-like-peptide-1). These changes lead to weight loss, improved blood sugars and often remission of type 2 diabetes but most patients do not qualify or want surgery. The investigators are searching for ways to make the beneficial effects of RYGB available to most type 2 diabetes patients rather than a select few that undergo RYGB. The investigators believe that parts of RYGB can be medically reproduced through a combination of diet and medicine. Once weekly injectable GLP-1 medicine that leads to weight loss and improved blood sugar control in type 2 diabetes are now FDA approved. Optifast is a medically supervised diet that safely reduces calorie intake to 800 calories per day for three months by replacing normal meals with specially prepared bars and shakes which leads to weight loss and improved blood sugar control in type 2 diabetes. Normal meals are then gradually reintroduced over 6 weeks and the bars/shakes are stopped. The investigators hypothesize that Optifast (diet) + once weekly GLP-1 will lead to weight loss and improvement in blood sugar control in type 2 diabetes similar to what is seen after RYGB.
The investigators long-term goal is to better understand novel interventions to promote cardiovascular health in humans. The goal of the proposed research is to investigate whether there is sex-specificity in the effects of dietary capsaicin on mechanisms regulating nitric oxide (NO) bioavailability, its effect on key markers of cardiovascular (CV) health, including BP, macro- and microvascular function, and arterial stiffness. This knowledge will provide critical insight into the effects of dietary capsaicin on CV health and will guide future trials.
This is a prospective, single center, open label study to assess the safety and effectiveness of microneedling with CBD and hempseed oil for the treatment of moderate to severe acne in adults 22-years of age or older.The objective of this exploratory study is to evaluate the safety and efficacy of HealMD's CBD with hempseed oil to reduce the appearance of moderate to severe facial acne.
