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.
The goal of this clinical trial is to evaluate the Eye Lipid Mobilizer (ELM) for the treatment of evaporative dry eye disease associated with meibomian gland dysfunction. The main questions aim to confirm that 1) the ELM can meet its intended use by validated patient reporting outcomes and 2) to confirm that the ELM device can be used safely by different users within a clinical environment as determined by review of any adverse events related to the use of the device.
The purpose of this study is to investigate the ability of an experimental dentifrice containing 1150 parts per million (ppm) fluoride to remineralize acid-softened dental enamel and help prevent further demineralization compared to a 0 ppm fluoride placebo dentifrice and a marketed, fluoride-containing dentifrice (Reference Dentifrice).
Pulmonary hypertension (PH) is an abnormal increase of the pressure inside the lung circulation. This condition can be caused by many different diseases. If PH persists for a long period of time, irreversible damage to the lung circulation and to the heart may ensue. A definitive diagnosis of PH requires direct measurement of the pressure within the lung circulation with a procedure called right heart catheterization (RHC). While overall safe, RHC is an invasive procedure and is associated with a small risk of complications (~1.1%) and, very rarely, death (0.055%), even when performed in experienced laboratories. Therefore, alternative diagnostic approaches are often employed such as an ultrasound technique called Doppler echocardiography which is non-invasive, relatively inexpensive and widely available technique. It is suitable not only as a screening tool but also for serial monitoring of disease progression in PH. However, the accuracy of Doppler echocardiography in measuring pressure in the lung circulation appears to be modest in patients with suspected PH. To improve the performance of Doppler echocardiography it is common practice to inject a small amount of agitated saline or an echocardiographic contrast medium (usually composed of microbubbles of fat containing a minuscule amount of a gas) into a vein. However, the accuracy of using agitated saline or a contrast agent in the measurement of pressures inside the lung circulation has not been established. The proposed study will assess the accuracy of Doppler echocardiographic measurements of pressures in the pulmonary circulation by simultaneously comparing the pressures collected during a RHC. The investigators will enroll 100 consecutive patients undergoing RHC in the Catheterization Laboratory of Northwestern Memorial Hospital. The investigators will measure pulmonary pressures by RHC and by Doppler echocardiography at baseline and following the injection of agitated saline as well as Optison®, an FDA-approved contrast agent commonly used in the echo laboratory. The investigators will then determine the accuracy of the Doppler echocardiography measurement without and with the use of agitated saline or Optison® with the measurements obtained during the RHC which is the gold standard. The results of this study will allow determination whether the use of echo contrast improves the accuracy of Doppler echocardiography and whether contrast-enhanced Doppler measurements are a clinically useful alternative to RHC measurements.
This study is being performed to evaluate the effect of different active workstations (e.g., standing, stepping, or walking stations) on work performance through the evaluation of neurocognitive function using reasoning, memory, concentration, and fine motor skills evaluation tools.
The overarching goal of this study is to establish initial proof of mechanism for precision interventions in an adult population.
The population of transgender and gender-diverse (TGD) persons in Wisconsin and the U.S. is steadily increasing. As this population grows, the number of individuals seeking gender-affirming therapies, including gender-affirming operations and gender-affirming hormone therapy, is also growing. An example of gender-affirming surgery is chest masculinization surgery, in which most breast tissue is removed in a person assigned female or intersex at birth to allow the chest to appear masculine. Gender-affirming chest masculinization surgery is not generally considered equivalent to an oncologic mastectomy, which aims to removal all breast tissue for future breast cancer reduction or current breast cancer treatment. The goals of this investigation are to 1) determine the percent of TGD persons considering chest masculinization surgery who have an elevated lifetime risk of breast cancer development and/or a pathogenic genetic mutation; 2) measure the percent who are at risk and choose to undergo risk-reducing mastectomies as part of chest masculinization surgery; and 3) assess and compare self-perceived breast cancer risk with calculated risk. The results of this study will substantially inform TGD patients and surgeons on the utility of personalized breast cancer risk assessment prior to chest masculinization surgery and the accuracy of self-perceived breast cancer risk in TGD persons.
Patients with chronic low back (cLBP) pain report reduced physical function and ability to participate in social roles and are more likely to use opioid pain medications. While self-management interventions have been shown to support these patients, effectiveness has been limited due to poor patient engagement. "Patient activation" encompasses the skills, knowledge, and motivation that a person has to manage the person's health. Supporting patient activation may improve the effectiveness of self-management for cLBP. In this single-masked pilot study of adults with cLBP, patients were randomized to receive either no intervention (control) or 6 weekly sessions of an evidence-based web-based self-management program (SMP) with or without health behavior change counseling (HBCC) using motivational interviewing. Participants were assessed at baseline and at 12 and 26 weeks using the Patient Activation Measure, Oswestry Disability Index and Patient-Reported Outcomes Measurement Information System (PROMIS) physical function, social role participation, and pain interference. The investigators assessed acceptability and feasibility based on recruitment, session attendance, and follow-up.
The goal of this Randomized controlled double-blinded trial is to compare the addition of a ketamine infusion to placebo, when added to standard care in adult blunt trauma patients with multiple rib fractures. The main question it aims to answer are: • addition of low dose ketamine infusion (LDKI) decreases narcotic use • does LDKI impact pulmonary complications, readmission, or hospital length of stay Participants will receive usual standard of care with up to 48 hours of LDKI or placebo. If there is a comparison group: Researchers will compare infusion of a saline infusion to LDKI to see if LDKI decreases need for narcotic analgesics use.
The goal of this randomized, single-blinded, educational study is to test the effect of providing crowdsourced ratings and feedback to second-year (PGY2) internal medicine (IM) and family medicine (FM) resident physicians' about their adverse event communication skills. The main question it aims to answer is: - Is the intervention of providing reports with personal performance feedback and recommendations for effective error disclosure associated with higher ratings of resident error disclosure skills? Participants will perform simulated error disclosure with a software tool called the Video-based Communication Assessment (VCA). Participants will be randomized to receive feedback reports (intervention) or not (control). Participants receiving the intervention will be asked to review their feedback and all participants will use the VCA again approximately 4 weeks later with different patient cases.
GEODESIC is a prospective descriptive cohort investigation that will examine the generalizability of the novel host gene expression biomarkers, SeptiCyteTM LAB, SeptiCyteTM VIRUS, SeptiCyteTM BACT, and SeptiCyteTM TRIAGE (collectively 18 genes or SeptiCyteTM LVBT) and SeptiCyteTM RAPID, for differentiating children with bacterial sepsis, versus severe viral illness, versus non-infectious related systemic inflammatory response syndrome.
