Background: The cause of fatigue is not well understood. It can be felt differently by different people. Some people think there are different types of fatigue, with different causes. Researchers think a therapy to treat one type of fatigue in one condition should be able to treat that type of fatigue in other conditions. Objective: To understand the types of fatigue. Eligibility: Adults 18 and older who have felt fatigue for more than a month, and non-fatigued adults Design: Participants will be screened with a physical exam, their medical history, a vision test, and blood and urine...
Patient Power is a patient research network and database (registry) to collect prospective information about demographics, self-reported diagnoses and medications, and willingness to participate in research from participants with rheumatoid arthritis (RA), spondyloarthritis (SpA), other musculoskeletal conditions, chronic neurological conditions like migraine, chronic pulmonary conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, autoimmune dermatological conditions such as psoriasis, and other chronic inflammatory or immune-mediated conditions. In addition, since patients with chronic conditions often have other...
Childhood chronic vasculitis describes a group of rare life-threatening diseases that have in common inflammation of blood vessels in vital organs such as kidneys, lungs and brain. Most knowledge about them comes from adult patients. Severe disease requires aggressive life-saving treatments with steroids and some cancer drugs which can themselves cause damage, and increase risks of cancer and severe infections. Conversely, milder disease can be treated with less toxic drugs. Different classification and "scoring tools" are used to define the types and severity of vasculitis and to measure damage caused by disease or drugs. These in ...
This study is an international, single arm, multicenter, prospective follow-up, non-significant risk, Post-Market Clinical Follow-up (PMCF), which is designed to collect safety and performance data on commercially available Perform® Fracture. Data collected from this study will be used for purposes, including but not limited to, PMS, peer-reviewed publications, education materials, future regulatory submissions, and/or product development.
The objective of this study is to perform a prospective, randomized controlled trial investigating the clinical usage of perioperative dexamethasone usage on APR activation, postoperative morphine usage, postoperative nausea, and hospital length of stay. There will be a control control and a Dexamethasone cohort. Participants will be randomized into one of the two cohorts. Patients in the control group will receive one 8mg dose of dexamethasone intraoperatively as per standard of care anesthesia protocols. Patients randomized to the dexamethasone cohort will be administered 8 mg of dexamethasone with 3 additional doses administered...
The primary objective of the study is a data collection initiative. The study will collect clinical and radiographic outcomes of patients implanted with patient specific rods. The secondary objective is to collect clinical and radiographic outcomes of patients with hardware as a control cohort to the patient-specific rods.
A randomized, controlled study comparing two total knee implant devices, Persona medial congruent (MC) vs posterior stabilized (PS). These surgeries will be performed using the ROSA robotic system. Patients will be followed up to 5 years.
The main objective of the study is to evaluate the safety, performance and clinical benefits of the Persona implant and its instrumentation in primary total knee arthroplasty
The study will evaluate the performance, clinical benefits and safety of the Persona Revision Knee System in patients who have received primary or revision total knee arthroplasty (TKA) treatment. This will be done using a multicenter, single-arm, consecutive series, retrospective cohort study with prospective follow-up.
The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treating provider.
