227 Clinical Trials for Various Conditions
Currently, ultrasound with or without AFP is the standard of care when it comes to surveillance for HCC in high-risk populations. While ultrasound is non-invasive and plays a critical role in detecting HCC, it is operator-dependent, inconvenient, and may have access issues in low-resource settings. Most critically, ultrasound is not sensitive enough to detect or confirm HCC in its most critical early stages, where treatment options are most effective and result in the best patient outcomes. AFP on the other hand, suffers from poor sensitivity and specificity generally, and its performance is insufficient for use as a surveillance tool. There remains a clear unmet need for a blood test that is sensitive enough to detect HCC in its early stages while being cost-effective and accessible for use as a surveillance tool. The investigators have previously demonstrated that serum liver cancer-secreted serine protease inhibitor Kazal (LC-SPIK) can reliably detect early HCC in addition to differentiating between it and other liver diseases. This study seeks to test the performance of the Seravue (LC-SPIK) device alone or in combination with other HCC diagnostic tests as a tool for HCC surveillance in diverse patient populations and clinical settings.

The SPARK Cognitive Status Indicator software uses an algorithm to assess a resting state EEG recording as being consistent with a cognitive status of unimpaired, mild cognitive impairment (MCI; MCI AD- or MCI AD+), or dementia (dementia AD-, or dementia AD+). This study will compare SPARK Cognitive Status Indicator output to Adjudication Committee panel-based diagnosis of cognitive status and Alzheimer's disease.
Complex Regional Pain Syndrome (CRPS) is an orphan condition with no interventions proven effective in large-scale clinical trials. In-person clinical evaluations are required to make a CRPS diagnosis and determine study eligibility, making recruitment for CRPS trials challenging. To address this barrier, we will validate a self-report measure of CRPS symptom severity suitable for remote administration that was created by colleagues at Vanderbilt University. The aim of this study is to evaluate the correspondence at the item and total score level between the proposed self-report measure (CRPS Severity Score-Self Report; CSS-SR) and an existing validated measure of CRPS signs and symptoms derived from clinical history and physical examination data (CSS-Clinician version) and evaluate its diagnostic accuracy relative to clinically determined, criterion-based CRPS diagnosis using the Budapest criteria.
The goal of this clinical trial is to compare the Kosmos Automatic Bladder Volume to the manual annotated bladder volume in participants across gender (male and female), age (children ages 7-17 and adults 18-89), and BMI strata (low to normal and high BMI). The hypothesis it aims to evaluate is: The Pearson correlation coefficient between Kosmos estimated bladder volume and manually annotated bladder volume will yield more than 0.90. Participants will: * Have their full bladders scanned and bladder volume calculated using the Kosmos Ultrasound Diagnositic System by both a nurse and sonographer. * Participants will void and measure their urine volume. * Participants empty bladders will be scanned and bladder volume calculated using the Kosmos Ultrasound Diagnositic System again by both a nurse and sonographer. * Three sonographers will manually annotate the pre- and post-void exam images for each patient to calculate the manually annotated bladder volume.
The clinical study is a multi-center, retrospective, blinded, matched-pair, two-arm clinical study in which one test assessment and a control assessment of liquid-based cytology (LBC) pap tests are performed and compared to a reference. The control method is defined as the assessment of LBC pap tests performed by a cytotechnologist (CT) and/or cytopathologist (CP) using standard laboratory cervical cytology practices (i.e. a manual assessment) and following The Bethesda System for Reporting Cervical Cytology (TBS). The control method is referred to as the "standard method". The test method is referred to as the AI-assisted method. The AI-assisted method is defined as the assessment of the same LBC pap test as in the standard method, but with the Techcyte SureView Cervical Cytology System, which has pap tests being scanned on the Pramana SpectralHT Cubiq whole slide scanner, analyzed with the Techcyte Cervical Cytology Algorithm (TCCA) and presented on the Techcyte Viewer, using the Dell U3223QE Monitor for assessment by a CT/CP following the TBS. In addition, the time spent reviewing the samples with both methods will be measured such that the CT workload limit for AI-assisted assessment can be established. The LBC pap tests to be assessed in the clinical study must have been prepared with either ThinPrep® Pap Test (Hologic) or BD SurePath™ (Beckton, Dickinson and Company). The study aims to enroll for each preparation method an equal number of samples.
Dual antiplatelet therapy (DAPT) is routinely recommended after percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation to prevent thrombotic complications. However, DAPT is also associated with an increased risk of bleeding, which may have a similar or even greater impact on prognosis compared to recurrent ischemic events. To balance these risks, individualized risk stratification at the time of PCI is crucial for determining the optimal DAPT composition and duration, aiming to reduce thrombotic risk while minimizing bleeding complications. For this purpose, an artificial intelligence-based risk stratification tool (xDAPT, Abbott) was introduced and demonstrated strong clinical performance in its development study (ClinicalTrials.gov identifier: NCT06089304). This analysis aims to evaluate the performance of xDAPT in a real-world cohort of patients who underwent PCI over the past decade at a large urban center (Mount Sinai Hospital, New York).

Urothelial cancers of the bladder and upper urinary tract account for over 200,000 deaths and 600,000 diagnoses annually worldwide. The most common presenting symptom is hematuria (blood in urine), triggering a cascade of tests, including an invasive examination of the bladder using a flexible scope (cystoscopy). Millions of cystoscopies are performed every year worldwide for patients presenting with hematuria, but only 10% result in a cancer diagnosis. The UROSCOUT-1 trial is a prospective multicenter observational study that explores the potential of urine tumor DNA (utDNA) testing to replace a significant portion of cystoscopies in the diagnostic setting for hematuria or other reasons to rule out urothelial cancer. The goal is to enhance patient quality of life, reduce healthcare costs, and address increased workloads in urology centers. Sample collection will be conducted by mail, and the samples will be analyzed in a blinded manner, without knowledge of which patients are diagnosed with cancer. Random subsampling will be applied to cancer-negative patients to achieve an approximate 1:1 ratio between cancer-positive and -negative patients.
Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS). Diagnosis is established by clinical assessment of persons with MS (PwMS), in combination with imaging and body fluid assessments. Treatment decisions in MS are mainly based on periodic monitoring of disease activity and progression through clinical and imaging assessments. The predictive and prognostic value of currently used assessments to individualize treatment decisions is still very limited. Emerging digital measures have the potential to provide granular health status measurements that would allow monitoring MS disease activity and progression continuously and remotely, in real-world settings, with minimal disruption of patients' life. Using the investigators' self developed dreaMS software program the investigators previously identified digital biomarkers (DB) that hold promise to provide detailed and accurate assessments of MS-related health status and disease progression to complement traditional clinical, imaging, or body fluid assessments. This international, observational study aims to evaluate and validate the generalizability of these DB across different languages and cultural settings to provide DB that are helpful for patient care, research, and regulatory decisions. Beyond this, the processes and data structures created for this study are intended to establish a collaborative research platform for subsequent studies, including pragmatic trials, promoting new long-term international academic collaborations.
