Langerhans Cell Histiocytosis (LCH) is a type of cancer that can damage tissue or cause lesions to form in one or more places in the body. Langerhans cell histiocytosis (LCH) is a cancer that begins in LCH cells (a type of dendritic cell which fights infection). Sometimes there are mutations (changes) in LCH cells as they form. These include mutations of the BRAF gene. These changes may make the LCH cells grow and multiply quickly. This causes LCH cells to build up in certain parts of the body, where they can damage tissue or form lesions. For most patients with LCH, standard-of-care vinblastine/prednisone are used as front-line therapy while cytarabine therapy has been used as therapy for patients who develop recurrence. No alternate treatment strategy has been developed for frontline therapy in LCH. The purpose of this research study is to compare previously used vinblastine/prednisone to single therapy with cytarabine for LCH. We will evaluate the utility of an imaging study called a positron emission tomography (PET) scan to more accurately assess areas of LCH involvement not otherwise seen in other imaging studies as well as response to therapy. We also want to identify if genetic and other biomarkers (special proteins in patient's blood and in patient's cancer) relate to the response of patients LCH to study treatment. Read Less

Inattentiveness and impulsivity in healthy adults and individuals with attention deficit hyperactivity disorder (ADHD) diminish these individuals' quality of life. Cortical hypometabolism has been hypothesized to contribute to inattentiveness in ADHD. Transcranial photobiomodulation (tPBM) is a safe and non-invasive modality for activation of the prefrontal cortex. tPBM in healthy adults has been shown to augment brain oxygenation, cognition, and mood. The cognition-enhancing effect of tPBM on sustained attention in adults with ADHD remains unstudied. The investigators will evaluate whether tPBM administration to adults with and without ADHD can improve their attention. Each participant will be screened for eighteen criteria based on the Diagnostic and Statistical Manual (DSM-IV, text revised), using the validated instrument Adult ADHD Self-Report Scale (ASRS-v1.1). Blinded participants will be randomized into (I) Active-tPBM or (II) Sham-tPBM groups. After undergoing an 8-minute administration of Sham or 1064 nm tPBM to the lateral and medial right prefrontal cortex, each participant will complete a 14-minute, computer-based Conner's continuous performance task-3 (CPT-3). The investigators will examine whether adults with and without ADHD who receive Active-tPBM improve in measures of inattention, impulsivity, sustained attention, or vigilance compared to the Sham-tPBM group. Cognitive assessments of attention like the CPT-3 may evaluate the efficacy of tPBM to increase cortical metabolism in healthy adults and individuals with conditions like ADHD. The investigators anticipate their investigation will be a starting point for more sophisticated studies that focus on the implications of tPBM on cognition. Read Less

The purpose of this study is to test feasibility of a comparative effectiveness framework for acute stroke imaging using prospective electronic health data. This is a prospective, cohort feasibility study of patients presenting to the Emergency Department with suspected acute ischemic stroke. The clinical stroke team will not be blinded to the imaging modality given the nature and purpose of the interventions/imaging. Knowledge of the imaging modality used and the knowledge gained from the resulting data will need to be considered for treatment decisions. Blinding will be maintained for data abstraction and analyses. Analysis will be on an "intent-to-scan" basis and all qualifying patients will be included in their assigned cohort. Read Less

This study aims to determine the immediate and short-term effects of treadmill oscillation walking (TOW) exercise on hip and knee neuromechanics and gait characteristics in individuals post-stroke. It was hypothesized that compared to baseline, individuals poststroke (N=15) will show increased hip abductor and knee extensor muscle activity and torque production, and increased limb loading and walking speeds during TOW and following a 6-week TOW intervention, reflecting that TOW can enhance gait function through improved hip and knee neuromechanical activation.

The goal of this clinical trial is to test a culturally tailored health promotion intervention for children with IDD and their families. First investigators will conduct a single group design pilot study of a health promotion intervention, followed by second, a small-scale randomized control trial (RCT). of the intervention with Latino parents of children with intellectual and developmental disabilities (IDD) in the Chicago, Illinois and Austin, Texas areas. The following research questions will be addressed: Question 1: What is the appropriate content, dosage, and delivery method of the intervention? Question 2: What is the feasibility and acceptability of the intervention? Question 3: Do participants improve between pre and post-test on outcome measures both in the one group design and compared to the control group in the RCT? Parents will receive 10 weekly remote sessions on health promotion content delivered by parent mentors called promotoras. Parents and children will attend 3 multi-family group workshops in-person that will provide demonstrations and interactive activities. Read Less

This is a multicenter, randomized, placebo controlled study to evaluate the efficacy and safety of ABX464 given at 25 or 50 mg QD in inducing clinical remission in subjects with moderately to severely active ulcerative colitis who have inadequate response, no response, a loss of response, or an intolerance to either conventional therapies \[corticosteroids, immunosuppressant (i.e. azathioprine, 6-mercaptopurine, methotrexate)\] and/or advanced therapies \[biologics (TNF inhibitors, anti-integrins, anti-IL-23), and/or S1P receptor modulators, and/or JAK inhibitors\].

Uncontrolled asthma in school-aged children is a significant public health problem. Latino children living in low-income contexts are at increased risk for uncontrolled asthma compared to non-Latino white children, and stress is an unaddressed factor in this disparity. Therefore, the purpose of the current study is to test an intervention program that teaches families skills to cope with asthma-related and other sources of stress. Specifically, the study will compare the effects of the combined coping skills + asthma management program with a standard asthma management program in 280 families of Latino children with asthma. The study will also look at why the program may have an effect, and specifically whether the program impacts child coping, parent coping, or family asthma management behaviors. The main hypothesis is that the combined coping skills + asthma management program will improve asthma outcomes more than the standard asthma management program. Read Less

This study is funded by the HEAL Initiative (https://heal.nih.gov/). Based on Preliminary Studies (PSs), the research team developed and pilot-tested an evidence-based Web App-based information and coaching/support program for cancer pain management (CAPA) that was culturally tailored to Asian American breast cancer survivors using multiple unique features. However, CAPA rarely considered depressive symptoms accompanying pain in its design or components, and PSs indicated the necessity of further individualization of the intervention components of CAPA due to diversities in the needs of ABD. The purpose of the proposed 2-phase study is to further develop CAPA with additional components for ABD and the individual optimization functionality (CAI) and to test the efficacy of CAI in improving cancer pain experience of ABD. The specific aims are to: a) develop and evaluate CAI through an expert review and a usability test (R61 phase); b) determine whether the intervention group (that uses CAI and usual care) will show significantly greater improvements than the active control group (that uses CAPA and usual care) in primary outcomes (cancer pain management and cancer pain experience including depressive symptoms) from baseline to post 1-month and post 3-months; c) identify theory-based variables (attitudes, self-efficacy, perceived barriers, and social influences) that mediate the intervention effects of CAI on the primary outcomes; and d) determine whether the effects of CAI on the primary outcomes are moderated by selected background, disease, genetic, and situational factors. This study is guided by the Bandura's Theory and the stress and coping framework by Lazarus and Folkman. The R61 phase includes: (a) the intervention development process, (b) a usability test among 15 ABD, 15 family members, and 15 community gatekeepers; and (c) an expert review among 10 experts in oncology. The R33 phase adopts a randomized repeated measures control group design among 300 ABD. Long-term goals are: (a) to extend and test CAI in various healthcare settings with diverse subgroups of ABD, (b) examine the costeffectiveness, sustainability, and scalability of CAI in the settings, and (c) translate CAI into health care for ABD.
