Prediction of Muscle Force Generation using Ultrasound Imaging and Computational Simulations

The objective of this study is to develop and validate a method to predict force production of individual muscles from ultrasound measurements of muscle stiffness, size, and structure. We will place acupuncture needles to the muscles and applied a small amount of current to induce contraction. Force and ultrasound measurements will be performed during muscle contraction. This process will be done in three muscles, one in the arm and two in the leg.

Imaging and Depression with or without MS

A study looking at the neural and genetic correlates of depression. Presently, the current study is looking to recruit individuals for two separate groups: 1. MS but NO history of depression 2. Depression but NO history of MS or neurological disease. The purpose of the study is to look at patterns of brain structure and function in individuals with depression and compare them to those with MS. We will explore how any differences we find contribute to more problems with depression in MS and see how such differences might lead to better treatment options for depression.

Functional magnetic resonance imaging (fMRI) and psychophysical studies of sensory perception and cognition

The purpose of this study is (1) to understand how the brain processes sensory information and (2) how this is affected by factors like blindness or synesthesia. In addition to behavioral testing, the study will use functional magnetic resonance imaging (fMRI) which enables us to take pictures of the brain while you are doing a task, using an instrument called an MRI scanner.

Site for Tomosynthesis Mammographic Imaging Screening Trial (TMIST)_EA1151_PSCI 19-080

This study is being done to answer the following question: Can tomosynthesis mammography, three-dimensional x-ray imaging of the breast, lower your chance of developing life-threatening breast cancer through routine screening compared with digital mammography, two-dimensional x-ray imaging of the breast? We are doing this study because we want to find out which of the two usual approaches to breast cancer screening are better in the early detection of life-threatening breast cancers.

Site for NRG-GU008, Randomized Phase III Trial Incorporating Abiraterone Acetate with Prednisone and Apalutamide and Advanced Imaging into Salvage Treatment for Patients with Node-Positive Prostate Cancer after Radical Prostatectomy (NCT #04134260)

The purpose of this study is to compare the use of hormone therapy and radiation therapy (usual treatment) to the use of apalutamide and abiraterone acetate with prednisone plus the usual treatment. The addition of apalutamide and abiraterone acetate with prednisone to the usual treatment could stabilize your cancer and prevent it from spreading. But it could also cause side effects, which are described in the risks section below. This study will help the study doctors find out if this different approach is better, the same, or worse than the usual approach. To decide if it is better, the study doctors will be looking to see if the study approach increases the time without prostate cancer spreading compared to the usual approach. The study drugs, apalutamide and abiraterone acetate with prednisone, are already approved by the FDA for use in prostate cancer. But, most of the time abiraterone acetate with prednisone is not used until hormone drugs stop working and apalutamide is not used until hormone drugs stop working and after prostate cancer has spread. There will be about 586 people taking part in this study.

Site for RANDOMIZED PHASE II/III TRIAL OF SENTINEL LYMPH NODE BIOPSY VERSUS ELECTIVE NECK DISSECTION FOR EARLY-STAGE ORAL CAVITY CANCER (NRG-HN006) (PSCI# 20-085)

The purpose of this study is to see if neck and shoulder function and pain are better after SLN biopsy surgery compared to the usual approach and to see if SLN biopsy surgery is as good as the usual approach in extending your time without cancer. SLN biopsy surgery is potentially less invasive compared to the usual approach, but it requires a radioactive imaging agent to see the lymph nodes and it could also cause side effects. These side effects are described in the risks section below. Your study doctor will choose the appropriate imaging agent, Lymphoseek or sulfur colloid, for use in your surgery. This study will help the study doctors find out if this different approach is better than the usual approach at improving neck and shoulder function. To decide if it is better, in the first part of the study, doctors will be looking to see if shoulder and neck function and quality of life are better after SLN biopsy surgery compared to the END surgery.

Examining elderly traumatic brain injury and risk for neurodegeneration

The purpose of this proposal is to understand the risk factors for Alzheimer’s disease after TBI, including time since diagnosis, ethnicity, and genetic predictors. In Aim 1 the goal is to collect data in a large group of individuals with TBI to understand these interacting factors in predicting cognitive decline. Then in Aim 2, in a sub-group of individuals we use brain imaging methods in order to determine the network response associated with neurodegeneration decades post TBI. Ultimately, the ability to monitor the neural network response to injury-specific factors in combination with risk/resiliency factors (e.g., genetic, health) may bring greater precision to rehabilitation in TBI and aid in identifying patients at risk for neurodegeneration years prior to onset. Three specific aims were designed to clarify the role of neural recruitment in recovery from TBI:

Neural Correlates of Cognitive Dysfunction in Postural Tachycardia Syndrome

Postural tachycardia syndrome (POTS) is a chronic syndrome in which the heart beats too quickly when standing. POTS primarily affects young women. People with POTS also experience symptoms such as feeling faint, fatigue, nausea, and mental clouding or "brain fog." “Brain fog” is one of the most bothersome symptoms of POTS and it is unknown why people with POTS experience this symptom. Some studies have shown that POTS patients have problems with attention, memory and executive function (ability to plan, organize information, and adapt to changes) while seated and when upright. In this study, we will evaluate how brain function during mental tasks is affected in people with POTS compared to healthy volunteers. All volunteers will complete mental tasks while lying down and standing. If eligible, we will measure brain activity using functional magnetic resonance imaging (fMRI).The findings from this study will increase our understanding of the mental complaints in people with POTS, to hopefully help with development of new treatments.

Site for Phase III IGRT and SBRT VS IGRT and Hypofractionated IMRT for Localized Intermediate Risk Prostate Cancer (NRG-GU005) (PSCI# 19-073)

The purpose of this study is to compare any good and bad effects of using stereotactic body radiation therapy (SBRT), a technique that gives treatment in a shorter amount of time compared to the usual radiation therapy. SBRT is experimental for treating this type of cancer. SBRT uses special equipment to position a participant and precisely deliver radiation to tumors in the body. Both the study and the usual radiation treatments use daily images to guide the radiation treatment to protect normal tissue. The study treatment, treatment over a shorter amount of time, may prevent the tumor from returning but it could also cause side effects. This study will allow the researchers to know whether this different approach using SBRT is better, the same, or worse than the usual approach. To be better, the study treatment should increase the time without the cancer coming back by six months or more compared to the usual approach, and show improvements in side effects to the bladder or rectum.

CHARM II: Chemotherapy for Ablation and Resolution of Mucinous Pancreatic Cysts: A Prospective, Randomized, Double-blind, Multi-center Clinical Trial

This study seeks to verify the findings of the CHARM I pilot study by conducting a multi-center clinical trial. We hypothesize that: • Pancreatic cyst infusion with a specifically designed drug therapy cocktail following normal saline lavage will result in cyst destruction rates that do not significantly differ from those achieved by alcohol-based cyst treatment (ethanol lavage followed by infusion of the same chemotherapeutic cocktail). • The removal of alcohol from the procedure will decrease both serious and minor adverse event rates associated with pancreatic cyst treatment. • There may be molecular markers contained within the fluid of these cystic tumors which identify cysts that are favorable to or resistant to EUS-guided fine needle infusion using this drug combination. As such, we will test all treated cysts for 10 of the best known molecular markers for evaluation in post study analysis. We expect that administering a specifically designed chemotherapeutic cocktail without prior alcohol lavage will result in an equivalent rate of cyst resolution with fewer complications when compared to alcohol. The results of this study will provide important information about the most efficient and safest method for treating premalignant pancreatic cysts, an important step for treating these lesions with a minimally invasive technique and preventing their progression to cancer. Standard alternative treatment options for this patient group (if not taking part in this study) would be ongoing periodic radiographic monitoring with MR or CT imaging waiting for signs of cancer to develop or to consider surgical removal of the affected tissue.

Examining responses to rewards in the laboratory and during daily life in individuals who smoke cigarettes

The goal of this study is to learn more about how people who smoke cigarettes respond to rewards, such as winning money, under different conditions. The study uses a method called functional magnetic resonance imaging, or fMRI, which is a research method for measuring activity in the brain. In this study, we are using fMRI to measure how brain activity changes in people who smoke when they receive rewards. The fMRI measures are collected during two separate visits. Participants are also asked to fill out questionnaires and complete computer tasks while in the lab. In addition, the study involves measuring thoughts and behaviors in people who smoke in real life by asking them to fill out surveys on a smartphone. Participants are asked to carry a smartphone for a total of 10 days and answer several surveys throughout each day. In order to be eligible for the study, individuals must be between 18 and 55 years old and you must smoke on a daily basis.

Examining contextual factors associated with food-related reward and eating restraint

Rates of obesity have risen sharply throughout the world over the past several decades. The increase in the availability of highly palatable, high-calorie foods may be one factor that has contributed to this trend. That is, the availability of such foods may lead to their over-consumption and corresponding weight gain. Currently, relatively little is known about how the availability of foods, per se, affects things such as the motivation to eat and the ability to resist doing so. The current study is designed to help address this knowledge gap by examining the effects of food availability in people with high levels of dietary restraint. Dietary restraint, which refers to the intention to restrict food intake deliberately in order to prevent weight gain or to promote weight, is linked to problematic patterns of eating. This project uses laboratory tasks and brain imaging to study the effects of food availability on various outcomes, including food choices, food craving, and responses in brain areas linked to motivation.
