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.
A Post-Market, Multi-Center, Prospective, Interventional Study for Treatment of Chronic Venous Disease of the Great and Small Saphenous Veins and Incompetent Perforator Veins.
This is an observational, retrospective, cohort study using administrative insurance claims data. The aim of this non-interventional study (NIS) is to compare maternal, fetal and infant outcomes of women exposed to Wegovy during pregnancy to a reference population not exposed to Wegovy, so that participants and healthcare providers can make informed treatment decisions.
This stepped-wedge, cluster-randomized pragmatic trial among six hospitals at University of Pennsylvania Health System will test a behavioral intervention embedded within the electronic health record that nudges hospital clinicians to either provide palliative care (PC) themselves (generalist PC) or consult specialists (specialty PC) for inpatients at high risk of death within 6 months. The trial will evaluate the intervention's effect compared to usual care on the primary outcome of hospital-free days through 6 months, and other patient-centered, clinical, and economic outcomes. The trial also includes an embedded mixed methods study to understand clinician and hospital contextual factors that influence the intervention's uptake.
The purpose of this study is to measure the impact of thyroid radiofrequency ablation procedure on patients with thyroid-related symptoms using a modified pre-existing scoring system.
The study has two arms, where the same natural language processing (NLP) and probabilistic graphical modeling technology will be utilized on patients' report of symptoms in both arms. The clinical arm is focused on patients presenting for consultation with a gastroenterologist. The endoscopy arm is focused generally on patients presenting for a diagnostic endoscopy, with the goal of capturing Functional Gastrointestinal Disorder (FGID) patients prior to diagnosis.
This is an international, single arm, multicenter, prospective, non-significant risk, Post-Market Clinical Follow-up (PMCF) study. Data will be collected for the commercially available AEQUALIS FLEX REVIVE shoulder system in both the anatomic and reversed configurations. The purpose of this study is to collect data needed to satisfy the European Union (EU) Medical Device Regulation (MDR) clinical post-market surveillance (PMS) and reporting requirements, and to support future regulatory submissions and peer-reviewed publications on device performance and safety.
The mission of corrections is to provide care, custody, and control for incarcerated individuals. United States prisons are required by law to provide adequate care for growing numbers of older people who are incarcerated-a group who are disproportionately at risk for Alzheimer's Disease and Related Dementias (ADRD). This Phase I project focuses on research and development of highly interactive computer-based learning modules, for prison staff and people who are incarcerated and serving as peer caregivers, to promote an integrated systems approach for enhancing the care of people with ADRD in prison.
The goal of this study is to identify and develop multiparametric quantitative ultrasound imaging (QUI) biomarkers for assessing upper trapezius muscle with and without chronic neck pain and their response to treatment. This goal will be achieved by testing the underlying hypothesis that abnormal muscle tissue can be identified based on its physio-mechanical properties, and that changes in these properties can be used to guide and monitor treatment progress. Preliminary results have shown that biomarkers including muscle B-mode ultrasound echo-intensity, shear wave velocity, and longitudinal strain ratios associated with muscle tissue structure, mechanics, and function significantly differ between muscles in low back pain and neuromuscular disorders and normal muscles. This study will determine which biomarkers are best suited to differentiate abnormal muscle in chronic neck pain from healthy muscles and develop a quantitative objective program for chronic neck pain management.
Dysphagia (swallowing impairment) is a serious health condition seen in many age-related disease and injury processes. Although videofluoroscopy (VF) is an international "gold standard" dysphagia diagnostic exam, there is a paucity of available normative physiologic VF reference values in healthy adults across the age span to guide interpretation of these examinations. In this project, the investigators will extend previous work on the quantitative measurement of swallowing physiology from VF examinations to establish reference values for swallowing in healthy adults, and to identify clinical decision point values for differentiating healthy swallowing across the age span from disordered swallowing in several high-risk clinical populations to study dysphagia.
The goal of this study is to target the neurobiology of restricted and repetitive behaviors in children with autism spectrum disorder using N-acetylcysteine (NAC), a well-tolerated nutritional supplement that has shown promise for reducing symptom severity in recent small-scale trials. The findings from this research will shed light on the mechanisms of action underlying the clinical benefits of NAC and the effects of NAC on altering restricted and repetitive behavior symptom severity in children with autism spectrum disorder.
