Los Angeles, CA Paid Clinical Trials

The purpose of this study is to evaluate the efficacy and mediators of change in Positive Affect Treatment, a psychotherapy specifically aimed at enhancing reward sensitivity in individuals with low positive affect (a core feature of anhedonia) in the context of depression or anxiety. Target enrollment is 100 male and female participants with low positive affect and depression or anxiety and impaired functioning, between the ages of 18 and 65 years, who will be randomized to either Positive Affect Treatment or Negative Affect Treatment (designed to reduce threat sensitivity). Participants will complete laboratory tests, psychiatric assessments, and self-report questionnaires as part of the study. The total length of participation is around 5 months. Read Less

Childhood obesity is a national epidemic that disproportionately burdens low income and ethnic minority populations. By preschool, nearly one-third of low income children are already overweight or obese, setting the stage for adverse health outcomes over their life course. Evidence is mounting that individual-focused, single-component interventions fail to produce long-term population-level changes in obesity-related outcomes. Evidence increasingly supports creating entire environments (e.g., schools) in which the healthy choice is the default option. The investigators will conduct a pragmatic cluster randomized trial to evaluate the effectiveness of a multilevel (organization, teacher, parent, child) intervention to support healthy eating and physical activity in preschools. The study is being conducted in partnership with Child Care Resource Center (CCRC), a non-profit organization dedicated to ensuring that all children receive high quality preschool experiences. The investigators will randomly assign 60 preschool sites (stratified by size), located in underserved areas of Los Angeles, to the intervention or a usual practice control conditions. The investigators will evaluate the effectiveness of the intervention on child BMI z-scores (primary outcome) and parent-reported child nutrition and physical activity (secondary outcomes). The investigators will systematically examine the implementation process to understand factors that may facilitate or hinder intervention uptake and success. The findings from this work will be critical for informing future dissemination efforts. Read Less

Patients with inflammatory bowel disease (IBD) often have narrowed microbial diversity and altered composition and function of the gut microbiome. We anticipate the anti-inflammatory diet, when compared with the usual diet, to produce favorable changes in these multi-omics profiles. These findings will provide insight into the interactions between diet and host biology, while providing clues on the mechanisms of diet therapy's effect and CD pathogenesis. Read Less

Intracranial aneurysm rupture is a leading cause of hemorrhagic strokes which carry high mortality and disability rates as well as high healthcare costs. Unruptured intracranial aneurysms (UIA) are common in the general population, occurring in 1-2% of individuals. Previous studies have shown that UIA growth and rupture are strongly associated with each other, with growing aneurysms 9-12 times more likely to rupture, and nearly all aneurysms growing prior to rupture. Thanks to advanced medical imaging, UIA are now more and more often detected incidentally. However not all aneurysms qualify for preventive surgical or interventional procedures according to current International Study of Unruptured Intracranial Aneurysms (ISUIA) guidelines, and some must therefore be monitored for growth. Current guidelines are based heavily on size, an inconsistent predictor of future growth. To improve management strategies for individual patients and more comprehensively assess aneurysm risk, the investigators propose to identify risk factors related to growth. Aneurysm etiology is multifactorial, with both genetic and environmental contributions to aneurysm formation, growth, and rupture. Exploring new risk factors based on aneurysm natural history and understanding the mechanisms underlying aneurysm rupture have been extensive research areas. As previous studies have shown that quantitative imaging biomarkers (QIB) can provide a more accurate assessment of the characteristics of aneurysms, the investigators propose a combined study which identifies QIB associated with aneurysm growth to identify factors related to growth.

This study evaluates KRT-232, a novel oral small molecule inhibitor of MDM2, for the treatment of patients with myelofibrosis (MF) who no longer benefit from treatment with a JAK inhibitor. Inhibition of MDM2 is a novel mechanism of action in MF. This study will be conducted in 2 phases. Phase 2 will determine the KRT-232 recommended dose and dosing schedule; Phase 3 will test KRT-232 vs Best Available Therapy (BAT). Patients in the Phase 3 part of the study will be randomized 2:1 to receive either KRT-232 (Arm 1) or BAT (Arm 2). The BAT administered will be determined by the treating physician, with the option to "cross-over" to KRT-232 treatment after 6 months of BAT or if the disease worsens at any time. Read Less

This is a phase II pilot study designed to assess the safety and efficacy of danazol for treatment of cytopenias in patients with CPC A/B cirrhosis. Subjects with or without telomere mutations and/or shortened telomeres will be treated with danazol 600 mg per day by mouth for a duration of 24 months. The goal will be to treat a total of 10 patients. Read Less

The goal of this clinical trial is to follow the progress of wounds in those with venous leg ulcers and diabetic foot ulcers while using an absorbent dressing called Mepilex Up. The main objective is to follow the progress of these wounds over time from initial visit to each follow-up visit. Participants will be asked to wear Mepilex Up dressing for up to 6 weeks of treatment or until healed, changed at every one-week interval. Read Less

Adenoma detection rate (ADR) is a validated quality metric for colonoscopy with higher ADR correlated with improved colorectal cancer outcomes. Artificial intelligence (AI) can automatically detect polyps on the video monitor which may allow endoscopists in training to improve their ADR. Objective and Purpose of the study: Measure the effect of AI in a prospective, randomized manner to determine its impact on ADR of Gastroenterology trainees. Read Less

This study encompasses the maintenance and utilization of a repository of samples from patients with cerebrovascular disease and stroke. The types of tissue taken are blood, cerebrospinal fluid (CSF), tissue, and microdialysis samples. Future analysis of these samples can potentially help investigators to better categorize groups of patients, understand the underlying etiology of these pathologies, identify markers that are associated with favorable or poor outcomes, and track changes that occur during the natural course of the disease or with treatment. This is a prospective observational study which will use samples from such patients to create this library which can be used to explore these questions in the future. Read Less

Renuva is allograft adipose matrix commonly used as a filler in cosmetic procedures. The investigators are studying this material as an injectable in the vocal fold to treat glottic insufficiency. Currently, many products can be used as an injectable in the vocal fold to correct glottic insufficiency such as carbomethycellulose, hyaluronic acid, collagen derivatives and calcium hydroxyapatite amongst others. An ideal injectable would not impair the fibroelastic property of the vocal fold tissues and would integrate within the tissue of the vocal fold. Since Renuva has the property of stimulating adipogenesis by using growth factor and collagen, the investigators believe it could represent a good option in terms of safety and efficacy for vocal fold augmentation. This study will assess the safety and efficacy of Renuva as a vocal fold injectable to treat glottic insufficiency. Read Less
