Colorectal cancer is a leading cause of cancer death. Detection and removal of polyps can reduce risk for developing colorectal cancer. After finding and removing precancerous polyps, repeat colonoscopy is routinely recommended. However, it is unclear whether repeat additional colonoscopy further reduces risk for colorectal cancer. For older adults age 75 and older, the lack of this information is especially important, given that the risks of colonoscopy go up with age. This research will evaluate whether older adults with a prior history of precancerous polyps have higher colorectal cancer risks compared to older adults who had a prior normal colonoscopy, and whether, among those with prior precancerous polyps, repeating a colonoscopy after age 75 is associated with reduced cancer risk. The investigators will synthesize these data and gather perspectives from Veterans and clinical stakeholders to make recommendations on whether older adults with a prior history of polyps should continue or defer colonoscopy after age 75.

The purpose of this research is to study whether the use of pseudoephedrine can help prevent middle ear trauma during HBOT. Pseudoephedrine is an approved drug that is used for temporary relief of nasal or sinus pain and pressure. Read Less

Dental Fear and Anxiety is an emotional experiences affecting many children and adolescents which can lead to behavioral problems in the dental setting. The purpose of the proposed study is to investigate the effect of virtual reality on anxiety, behavior, and pain in children undergoing restorative dental procedures. Children enrolled in the study will include patients ages 6-18 who are healthy and require two or more dental sealants (at least one sealant per side). The participants in the study will serve as their own control using a split-mouth cross-over randomized control clinical trial design and will be randomly assigned to receive virtual reality or traditional behavior guidance techniques first during dental sealant placement. The objectives of this study are to explore the associations between the use of virtual reality distraction during dental sealant placement with Frankl score, FLACC scale, and anxiety based on the change in heart rate, and pain based on self-reported FPS-R when compared with to the control group. The crossover design will be assessed by a linear mixed model with patient treated as a random effect. This model will include treatment, visit, treatment by visit interaction term as well as a treatment sequence variable. Prior to analysis, the primary outcome measures will be assessed for normality using a Shapiro-Wilk statistic as well as quantile-quantile (QQ) plots. Should the data deviate sharply from a normal distribution, normalizing transformations will be sought and applied to the data. Read Less

The Periviable GOALS (Getting Optimal Alignment around Life Support) decision support tool (DST) is meant to facilitate informed shared decision-making regarding neonatal resuscitation for families facing the threat of a periviable delivery (deliveries occurring between 22 0/7 - 25 6/7 weeks gestational age). It is designed for parents to review independent of their clinician, and is intended to supplement, not replace, clinician counseling. The focus of the DST is the provision of patient-centered outcomes information and assistance with values clarification regarding neonatal outcomes. This is a multisite, randomized controlled trial to test the effect of the Periviable GOALS DST on shared decision making and decision satisfaction. The investigators hypothesize that participants who utilize the GOALS DST will have improved shared decision making and higher decision satisfaction. Read Less

The purpose of this study is to monitor physiological and molecular changes during and following CAR-T cancer cell therapy, towards improved management of adverse events including Cytokine Release Syndrome and neurotoxicity. Our study aims are to improved early detection and precise management of adverse events for patients receiving Chimeric antigen receptor T- cell (CAR-T): 1. To assess the feasibility, including accuracy, usability, and usefulness of wearable sensors in CAR-T patients. 2. To generate comprehensive multiomic profile analysis following CAR-T therapy. 3. To perform integrated analysis of wearables sensor data, omics data, and symptom/clinical data. Read Less

This is a Phase 1b/2 study evaluating FOR46 in combination with enzalutamide in patients with metastatic castration resistant prostate cancer (mCRPC) after prior progression on abiraterone. FOR46 is designed to target and bind to CD46, a transmembrane cellular protein expressed at moderate or high levels in numerous cancer types. The investigators hypothesize that the combination of FOR46 plus enzalutamide will achieve a clinically significant composite response rate with sufficient durability of response in mCRPC patients.

The QUIT-Mobile study proposes to use mobile phone self-monitoring and feedback to enhance and sustain over 12-months the impacts of the Quit Using Drugs Intervention Trial (QUIT), an effective screening and brief intervention (SBI) previously successful in reducing risky drug use (i.e., moderate use) in low-income, diverse patients over a 3-month follow up. The investigators will conduct the QUIT-Mobile study for patients who receive care in clinics of federally qualified health centers (FQHC) in Southern California over 12-months follow up. The study is an Effectiveness-Implementation Hybrid Type 1 design consisting of a single-blind, 3-arm, RCT with adult, mostly Latino FQHC primary care patients with risky drug use (ASSIST score 4-26), randomized to 3 conditions (n=200/arm, n=600 total): 1) QUIT-Mobile; 2) standard QUIT; 3) Usual Care. Qualitative data on implementation facilitators and barriers will inform future scale-up and sustainability, in addition to cost data analyses. The aims are to examine effectiveness in reducing risky drug use and cost-effectiveness comparing the three arms over 3-, 6- and 12-months. Drug use measures include self-reports for past 30-days and urine drug screen validation for underreporting (acknowledging that people with moderate risk drug use have sporadic drug use patterns requiring longer self-report recalls for drug use that urine screens may not detect). The 3-arm study enables testing of the independent and synergistic effects of QUIT-Mobile compared to QUIT and both to Usual Care. The 12-month timeline reflects annual primary care visits when screening and brief intervention would be repeated routinely. The QUIT intervention contains 3 primary components: 1) patient screening with the WHO ASSIST, 2) brief clinician advice (\<3 minutes) including opioid overdose prevention education, and 3) 2- and 6-week telephone drug-use health coaching sessions utilizing motivational interviewing and cognitive behavioral techniques, delivered by paraprofessional health coaches. QUIT-Mobile tests the addition of mobile phone self-monitoring, automated feedback, and coach monitoring dashboard to enhance and sustain QUIT\'s drug use reductions using mobile-web app, text-messaging (SMS), or interactive voice response (IVR).

The purpose of this study is to test the safety of an investigational drug called CFI-402411 alone and in combination with pembrolizumab and to study its effects in patients with advanced solid tumors who have progressed following previous therapies. Read Less

This phase II trial studies how well standard of care hypofractionated radiation therapy followed by durvalumab with or without tremelimumab works in treating patients with hepatocellular cancer (liver cancer) that has spread to other places in the body (advanced) and that is growing, spreading, or getting worse (progressing) after treatment with PD-1 inhibitor immunotherapy. In some patients, cancer cells and immune cells start to express signals that stop the body's immune system from killing the cancer. New drugs being developed, such as durvalumab and tremelimumab, are designed to target and block these signals and may help increase the immune response to prevent or slow down cancer growth. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may help the immune system work even better. Giving durvalumab with or without tremelimumab after radiation therapy may work better than radiation therapy alone in treating patients with liver cancer. Read Less
