MELPIDA is proposed for the treatment of subjects with SPG50 and targets neuronal cells to deliver a fully functional human AP4M1 cDNA copy via intrathecal injection to counter the associated neuronal loss. Outcomes will evaluate the safety and tolerability of a single dose of MELPIDA, which will be measured by the treatment-associated adverse events (AEs) and serious adverse events (SAEs). Secondarily, the trial will explore efficacy in terms of disease burden assessments. Read Less

The purpose of this study is to see if 18F-fluciclovine (Axumin®) PET imaging is useful and safe in the management of children with High Grade Gliomas. Investigators seek to determine if this imaging will help doctors tell the difference between tumor growth (progression) and other tumor changes that can occur after treatment. Read Less

Mild traumatic brain injury (mTBI), also known as concussion, is a common injury sustained by Veterans. While most individuals who sustain mTBI experience a complete recovery within several weeks of injury, many Veterans with history of mTBI report frequent and long-lasting neurobehavioral complaints and functional impairment. Though research suggests that these outcomes are strongly influenced by co-occurring conditions such as post-traumatic stress disorder, depression, and chronic pain, evidence-based interventions capable of addressing this wide array of concerns are lacking. This study seeks to address this gap by evaluating the effectiveness of a brief and flexible behavioral health treatment (Problem-Solving Training for Concussion, or PST-Concussion), which was designed to be delivered by generalist providers working in VA primary care settings. If PST-Concussion is shown to be effective, this skills-focused intervention may help improve Veterans' recovery experience following mTBI. Read Less

The purpose of this study is to see how effective non-steroidal anti-inflammatory drugs (NSAIDs) are at controlling pain without side effects in participants after robotic-assisted partial nephrectomy. Read Less

There is significant, proven use of radiation for recurrent prostate cancer after surgical resection. This treatment typically is delivered over seven and a half weeks of daily treatments, presenting a burden to patients and the health care system. Stereotactic body radiation (SBRT) is a radiation technique in which large doses are delivered over a short period of time. To date there is extremely limited evidence in SBRT for recurrent prostate cancer after surgery, with a significantly growing body of evidence for primary SBRT treatment of prostate cancer in men who opt for non-surgical upfront treatment. Additionally, advances in imaging have allowed better detection of the site of recurrence, and novel artificial intelligence aided daily-adaptive radiation therapy have allowed more precise delivery of radiation doses. This study seeks to evaluate the role of Daily-Adaptive with AI-assisted SBRT in the post operative setting utilizing Ethos Plan Adaptive technology in attempt to maintain control and minimize side effects.

This is a non-randomized Phase 2 study of sacituzumab govitecan (IMMU-132) in subjects with recurrent or persistent platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancers. Read Less

This study will assess how two different ablation strategies, using two different ablation catheters during catheter ablation for paroxysmal atrial fibrillation, affect the temperature of the esophagus during ablation, and the risk of injury to the esophagus. Read Less

This is a prospective, open label, multicenter, single arm, first in human clinical study. Patients with infra-inguinal peripheral arterial disease appropriate for treatment with a femoro-popliteal stent will be enrolled. The patients will be treated with the ChampioNIR Stent System. All implanted patients will be followed up at 30 days and 6, 12, 24 and 36 months. The follow-up visits will include patency evaluation by duplex ultrasound Read Less

This study is to investigate characteristics of muscle, blood, and urine samples from older adults (ages 65-80) who are either sedentary or athletes performing at an elite level for their age. This observational study will include bio-specimen collection, as well as physical and cognitive function testing and body composition. Read Less

The goal of this clinical trial is to test a new web-based promotora de salud/ community health worker (CHW) training. This training is designed to provide CHWs with the knowledge and skills to effectively implement a healthy living intervention for Latinas. The main question it aims to answer is: o Do CHWs who complete the web-based healthy living training have higher self-efficacy in implementing core lifestyle intervention learning components for obesity interventions in Hispanics than CHWs who do not? Participants will: * Complete a baseline survey asking about self-efficacy related to implementing core lifestyle intervention learning components, knowledge, health behaviors, and skill mastery. * Be randomized to receive the new web-based training or to a standard CHW training designed by Health and Human Services. The new web-based training provides promotores with the self-efficacy, knowledge, and skills required to effectively implement an obesity intervention for Hispanic women. Promotores will build their skillset through interactive quizzes, exercises, video role-playing scenarios, and interactive tools. * Complete follow-up surveys at 3 months and 6 months after the baseline survey. This survey will ask the same questions as the baseline survey and will include additional questions regarding satisfaction with training and behavior application. Researchers will compare participants who receive the new web-based training to participants who utilize the HHS training. The goal is to see whether the new web-based training increases self-efficacy among CHWs to effectively implement core lifestyle learning components for obesity interventions in Hispanics. Read Less

The proposed study will test whether a working memory training (WMT) program improves fear extinction learning and its underlying neural circuitry in Veterans with posttraumatic stress disorder (PTSD). WMT is designed to improves the ability to maintain task-relevant information in mind. The project will further validate the relationship between working memory and fear extinction using novel computational and multivariate analyses that link to specific PTSD symptoms. If WMT can enhance fear extinction learning, then WMT may be a powerful adjunctive treatment that can enhance exposure therapy outcomes or be leveraged as a stand-alone treatment. This project supports the Department of Veteran Affairs mission of developing viable targets of treatment for Veterans with PTSD. Read Less

The purpose of this research study is to characterize the mechanisms contributing to cognitive impairment and accelerated cognitive decline in Late Life Depression (LLD). This is a non-randomized, observational, non-treatment study that originally launched in 2015, enrolling 133 participants. From the originally enrolled participants, the continuation of the ADNI-D study will enroll 120 participants which will include following participants from the original (parent) protocol and enrollment of new participants for a period of 30 months. Data from an additional 300 non-depressed subjects will be used from ADNI studies for comparison. Depression history, symptom severity and health information will be collected at the initial visit to determine eligibility. An magnetic resonance imaging (MRI) scan, as well as amyloid (florbetapir) and tau (flortaucipr) positron emission tomography (PET) imaging will be conducted at San Francisco VA. Collection of plasma and serum for biomarkers, clinical assessments and cognitive assessments will be conducted at two time points. Blood samples will also be collected for genetic analysis. Read Less
