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 purpose of this study is to evaluate a new radiation planning and treatment delivery technique called Deep Inspiration Breath Hold (DIBH) and expiration technique. This technique will be used to treat patients who have tumors close to the chest wall and are candidates for Stereotactic Body Radiation Therapy (SBRT). This study will assess the reduction of radiation to the chest wall during treatment using this technique.
This proposal is a partnership between Mental Health America (MHA), a nonprofit mental health advocacy and resource organization, Talkspace (TS), a for-profit, online digital psychotherapy organization, and the University of Washington's Schools of Medicine and Computer Science Engineering (UW). The purpose of this partnership is to create a digital mental health research platform leveraging MHA and TS's marketing platforms and consumer base to describe the characteristics of optimal engagement with digital mental health treatment, and to identify effective, personalized methods to enhance motivation to engage in digital mental health treatment in order to improve mental health outcomes. These aims will be met by identifying and following at least 100,000 MHA and TS consumers over the next 4 years, apply machine learning approaches to characterizing client engagement subtypes, and apply micro-randomized trials to study the effectiveness of motivational enhancement strategies and response to digital mental health treatment.
Directly examine whether early (6-month) imaging with DaTscan and [¹⁸F] AV-133 will provide an early signal of disease progression in recently diagnosed untreated PD patients.
Neoadjuvant accelerated methotrexate/vinblastine/adriamycin/cisplatin (AMVAC) in combination with nivolumab is under evaluation for the treatment of muscle invasive bladder cancer (MIBC). Patients with pre-specified tumor mutations and complete clinical response with neoadjuvant therapy will preserve their bladders and go on active surveillance.
The current standard of care for cochlear implants (CI) does not address the significant pitch-place mismatch that is inherent in cochlear implantation (see detailed description below). The present study uses postoperative Flat Panel (higher resolution than standard) CT imaging to measure where CI electrodes sit within an individual's cochlea; doing so allows for more accurate frequency mapping (and thus pitch perception). The hypothesis of this study is that long-term (1 year) use of CT image-based frequency maps, beginning on the first day of CI activation, will improve user performance in the areas of speech and music perception, as compared to the use of default programming settings.
Very few studies have compared robotic-assisted (RRBS) versus laparoscopic revisional bariatric surgeries (LRBS). To date, there has not been a prospective study comparing the perioperative outcomes of patients undergoing robotic-assisted and laparoscopic revisional bariatric surgery. This study aims to enroll patients undergoing RRBS and LRBS and evaluate the outcomes through 45 days, including the perioperative period. We hypothesize that RRBS may be associated with lower rates of perioperative outcomes.
Electronic screening is effective for timely detection of, and intervention for, suicidal ideation and other mental health symptoms. The VA eScreening program is a patient self-report electronic screening system that has shown promise for the efficient and effective collection of mental and physical health information among Veterans. However, additional effectiveness and implementation research is warranted to evaluate the impact of eScreening within VHA. This study will address questions of the impact of eScreening compared to screening as usual, while evaluating a multi-component implementation strategy (MCIS) for optimal enterprise rollout of eScreening in VA Transition Care Management clinics.
This clinical trial is a Phase I dose escalation and dose expansion and Phase II monotherapy open-label, first-in-human, multicenter study of OP-1250 in adult subjects with advanced and/or metastatic hormone receptor (HR)-positive, her2-negative breast cancer.
This is a randomized, open label, adaptive platform trial to compare the effectiveness of antithrombotic and additional strategies for prevention of adverse outcomes in COVID-19 positive inpatients
The central hypothesis is that inflammation mediators are biomarkers of both systemic diabetes and Diabetic Retinopathy (DR) progression in the aqueous and that sustained topical ketorolac application reduces/suppresses those inflammatory mediators thereby reducing the progression of Diabetic Retinopathy.
