8 Clinical Trials for Various Conditions
Cytopathologists work along with radiologist in the diagnosis of lesions. Rapid on site interpretation (ROSE) of fine needle aspiration (FNA) smears of radiologically suspicious lesions is a common clinical practice. In the last years, the investigators have seen trend towards needle core biopsies of radiologically suspicious lesions. The investigators want to analyze the challenges of rapid on site interpretation of touch imprints (TI) of needle core biopsies (NCB) versus fine needle aspiration smears.
The purpose of this study is to look at the safety (what are the side effects)and efficacy (how well does it work) of Dotarem® when used in taking images of the brain / spine. The results will be compared to the results of MRI taken without Dotarem.
This is a study to determine if a video that utilizes a peer to teach self administration of subcutaneous depot medroxyprogesterone is both effective and well accepted by adolescent patients who are already receiving ongoing treatment with depot medroxyprogesterone by a medical provider via an inter muscular injection. Self administration can be done at home and therefore offers an alternative to traveling to a medical office.
The aim of this research protocol is to test the efficacy of a self-care intervention through a randomized controlled trial (RCT), for increasing protective sexual health behaviors among youth in the participating Native American community. The investigators will randomize 450 youth and young adults ages 14-26 to the self-care intervention or a control program. Efficacy data will be collected up to 6 months post-intervention. The primary outcome will be uptake of sexually transmitted infection (STI) screening. Secondary outcomes will include: a) sexual risk and protective behaviors; and b) psychosocial assets and resources. The investigators hypothesize the self-care intervention will increase protective behaviors by: i) helping youth gain knowledge of their own sexual health risks, assets and resources; ii) motivating protection of those assets and resources; and iii) encouraging good health practices and making responsible choices.
This study aims to investigate how knowledge of gluten immunogenic peptide (GIP) levels in stool and urine affects subsequent adherence to a gluten-free diet. Half of the participants will receive results in real-time using a home device and the other half will store samples to be tested at the end of the 30 week study. Participants will also have a diet review with a dietitian at the beginning of the end of their study and be asked questions about their symptoms, gluten-free diet adherence and quality of life.
The aim of this study is to assess a novel educational mobile and online application which will use images of pigmented skin lesions with question prompts to train future medical providers to more accurately detect malignant lesions. The hypothesis of this study is that this new educational tool will result in higher melanoma detection rates among future providers.
The goal of this research study is to evaluate the impact of a paraprofessional-delivered, culturally adapted, evidence-based intervention (EBI) on sexually transmitted disease (STD), substance use and poor mental/emotional health among American Indians (AI) through a Randomized Controlled Trial (RCT). These intertwining risks have produced marked disparities and have unique cultural and social determinants in Native communities. If aims are achieved, scientific knowledge and community-based practice will be advanced in areas vital to AI communities, and to STD and drug prevention science. Prior to this study, the investigators applied findings from research protocol (IRB#00005929) and adapted a brief intervention to reduce risk and increase protective behaviors for STDs, HIV/AIDS, substance use and poor mental/emotional health, and to promote STD screening. The specific aim of the current study is to compare the efficacy of the adapted brief intervention vs. a comparison condition on participants' condom use, STD screening and treatment-seeking behaviors, substance use and emotional/mental health outcomes at 3 and 6 months post-intervention.
This study examines the role of craniofacial dimensions and self-evaluation thereof in the protection afforded by masks commonly worn by the public as protection against aerosol contaminants. The effectiveness of instructions for self-evaluation of craniofacial dimensions will be tested against standard digital and manual craniometric methods. Approximately 500 (18-70 year old) subjects. After consenting to participate in the study, subjects will use a short self-assessment questionnaire to measure their craniofacial dimensions, and have their face measured using standard anthropological techniques and a 3D camera. They will then enter a chamber containing an atmosphere of aerosolized salt particles where the fitted filtering efficiency of 2 types of face masks will be measured briefly. Participation time is approximately 60 minutes.
