Common barriers to receiving appropriate guideline-driven care for patients with severe aortic stenosis include referral biases by primary care providers (lack of provider education), patient comorbidities (degree of fragility), as well as psychosocial issues and cultural barriers. Additionally, race, ethnicity, socioeconomic status (SES) and education level are shown to be persistent barriers to accessing healthcare services and healthcare systems, creating a significant practice gap between various patient populations. The most recent transcatheter valve therapies (TVT) registry data show that >94% of TAVR recipients are Caucasian, followed by less than 4% of African-Americans and Hispanics, respectively. There is a critical need to understand the barriers to treatment and care among severe aortic valve disease patients of disparate groups. This study is a multi-center, retrospective and prospective cohort study of patients diagnosed with severe aortic stenosis. Additionally, we will be surveying referring primary care providers, cardiologists and cardiovascular surgeons to assess their current referral practices for patients with severe aortic stenosis.

This study design has two components: 1) a cross-sectional assessment of brain activity and inflammation in migraine patients compared to healthy controls and 2) an assessment of 8 weeks of a combination therapy approach to treating migraine. Read Less

The goal is to document efficacy of PF-SCS therapy in a blinded fashion and better understand how SCS therapy works in the clinical setting. Overall the investigators hope to improve patient care and selection of candidates who have the best potential for effective pain relief from an expensive and invasive therapy. Read Less

The primary objective of the study is to evaluate whether a set of algorithms analysing acoustic and linguistic patterns of speech can detect amyloid-specific cognitive impairment in early stage Alzheimer's disease, based on archival spoken or written language samples, as measured by the area under the curve (AUC) of the receiver operating characteristic curve of the binary classifier distinguishing between amyloid positive and amyloid negative arms. Secondary objectives include (1) evaluating how many years before diagnosis of Mild Cognitive Impairment (MCI) such algorithms work, as measured on binary classifier performance of the classifiers trained to classify MCI vs cognitively normal (CN) arms using archival material from the following time bins before MCI diagnosis: 0-5 years, 5-10 years, 10-15 years, 15-20 years, 20-25 years; (2) evaluating at what age such algorithms can detect later amyloid positivity, as measured on binary classifier performance of the classifiers trained to classify amyloid positive vs amyloid negative arms using archival material from the following age bins: younger than 50, 50-55, 55-60, 65-70, 70-75 years old.

The purpose of this study is to determine the value of including dynamic vision testing into California State University, Northridge (CSUN) Athletics' established concussion protocol. The study's hypotheses are 1) dynamic vision testing will reveal vision impairments right after a person sustains a concussion, 2) these impairments may still be present upon clearance to return to play.

The present study is a 3-arm randomized controlled pilot study. Participants who call the Maryland Tobacco Quitline and are eligible for study participation are randomized to receive quitline tobacco cessation treatment as usual (TAU), TAU plus remote carbon monoxide (CO) monitoring via smartphone app, or TAU plus remote carbon monoxide monitoring plus incentives vis smartphone app. We hypothesize that remote CO monitoring will be feasible and acceptable to deliver in the quitline setting, will increase treatment engagement, and will increase tobacco cessation and treatment satisfaction rates.

The aim of the study is to generate novel minimally-invasive serum protein signatures and biomarkers in children and adolescents with Crohn's Disease (CD) that correlate with and can predict and monitor patients who will have a prolonged response to Infliximab so that personalized medicine can be applied to patients with CD.

The goal of this investigation is to assess whether or not there is a significant difference in the presence and/or degree of post-operative ecchymosis, pain, and edema between groups of patients undergoing upper lid blepharoplasty with traditional local anesthetic (LA) and those who receive tranexamic acid (TXA) in addition to traditional LA.

The Leukemia and Lymphoma Society (LLS) has built a National Research Registry to evaluate real world experiences and medical outcomes for people with blood cancer, before, during, and after blood cancer treatments. Read Less

This project aims to monitor the side effects of COVID-19 vaccines worldwide actively. The primary objectives of the project include a) to estimate the prevalence of each local and systemic side effect of each COVID-19 vaccine among healthcare workers (HCW), old adults over +65 (OA), and schoolteachers (ST); b) to evaluate the potential demographic and medical risk factors for side effects frequency and intensity; c) to evaluate the long-term consequences of COVID-19 vaccines. The secondary objectives include a) to evaluate the relative safety of COVID-19 vaccines compared to each other; b) to evaluate the impact of palliative drugs used by the recently vaccinated individuals on their short-term side effects resolution.

This research study proposes to determine how well tolerated and effective lower and upper oral dental devices are at reducing snoring. The device is designed to move the genioglossus muscle forward, with interior attachment to maintain forward placement of of he tongue on the bottom of the mouth. Read Less

This study will identify a patient population who wishes to address a variety of concerns about the size, shape, or appearance of their penis with the placement of a subcutaneous Silicone Block Penile Implant. Because the Silicone Block is placed subcutaneously, the device can provide immediate and permanent improvements to the appearance of a man's penis. The most notable improvements are enhanced penile cosmesis, improved penile girth, and improved exposure of the penile shaft outside the plane of the body. The plan is to conduct a study to examine the outcomes of this procedure with respect to: Incidences of adverse events Changes in flaccid penile length (through physical measurements pre and post-operatively in a consistent manner) Changes in flaccid penile girth (through physical measurements pre and post-operatively in a consistent manner) Changes in satisfaction scores with respect to penile size and patient self-confidence/self-esteem (through validated questionnaires) Read Less
