20 Clinical Trials for Various Conditions
Background: Hemophagocytic lymphohistiocytosis (HLH) is a disease caused by disrupted immune function. People with HLH are prone to fevers and illnesses, which can be fatal. Some people develop a genetic form of this disease (pHLH), but researchers do not understand why some other people develop a nongenetic form (sHLH). They also do not have good ways to diagnose and treat sHLH. Objective: To learn about sHLH and why some people get it and others do not. Eligibility: Adults aged 18 years and older with sHLH. Design: Participants will be admitted to the study based on a review of their medical records. Those who join will have at least 3 clinical evaluations over 9 to 12 months. These may occur during an inpatient hospitalization if they require medical care or in the outpatient clinic. Participants will also have a physical exam at each visit. Up to half a cup of blood will be drawn at each visit. Participants may also have their blood drawn by their own doctors, who will send the samples to the researchers. Researchers may also contact these participants by telephone or video calls. The blood will be used for clinical tests as well as research. No new treatments will be administered as part of this study; however, standard medications and treatments may be recommended. Participants may opt to continue their visits once a year for 3 more years. Participants may also opt for an extra clinial evaluation 1 week after starting a new treatment....
The primary objective of this prospective observational study is to characterize the gut and oral microbiome as well as the whole blood transcriptome in gastrointestinal cancer patients and correlate these findings with cancer type, treatment efficacy and toxicity. Participants will be recruited from existing clinical sites only, no additional clinical sites are needed.
This is a multi-center randomized controlled evaluator-masked trial designed to compare metagenomic deep sequencing (MDS) versus standard of care testing for improvement of outcomes for intraocular infections. Patients with presumed intraocular infections who meet the eligibility criteria will be randomized to receive MDS testing results or not to receive MDS testing results. All patients will receive standard-of-care testing to guide management. Enrolled patients will be followed at week 2, week 3-6 (randomization visit), and at 4 weeks after the randomization visit. The proportions of patients who received the appropriate therapy and the proportions of patients with improved outcome will be compared between arms. Patient quality of life, MDS performance, and the provider certainly of belief will be collected.
This pilot study will evaluate new methods for the collection, storage, shipment, and RNA extraction of skin tape specimens from children with atopic dermatitis (AD) that will facilitate the multi-center SunBeam Birth Cohort study. Additionally, this pilot study will test new methods for the generation of whole transcriptome sequencing data from skin tape RNA and whether these data reflect the transcriptional state of the skin in health and disease.
This is an observational cohort study of 221 breast-feeding mother-infant dyads delivered at term. The goal of the study is to investigate whether levels of immune-related microRNAs (miRNAs) in maternal breast milk (MBM) influence child atopy risk in the first 12 months, defined as atopic dermatitis, wheezing, or food allergy. Infant exposure to individual miRNA components will be quantified at 0, 4, and 16-weeks after delivery using high throughput RNA sequencing of MBM samples and detailed dietary logs employing the Infant Feeding Practices (IFP) survey. The relationship of individual miRNA exposures (parts per million) and presence/absence of atopy in the 48 weeks after delivery will be assessed, while controlling for environmental exposures (National Survey of Lead hazards and Allergens in Housing), maternal diet, and genetic predisposition. Potential transfer of MBM miRNAs to the infant oropharynx and subsequent impact on immune reactivity will also be explored through RNA sequencing of infant saliva and quantification of cytokine profiles.
Assess impact of Tart Cherry Concentrate in cardiac surgical patients on POAF and related clinical and economic outcomes. Measure inflammation gene transcripts in cardiac tissue.
A PRoBE design study will be used to obtain saliva from patients before undergoing blood study evaluation for screening at risk patients for the presence of undiagnosed pre-diabetes of type II diabetes. Pre-specified saliva biomarkers will be evaluated along with multi-marker models for their discriminatory value for distinguishing patients with normal glucose metabolism from those with disease. Appropriate housekeeping genes will also be incorporated to allow for the measurement of relative gene expression.
Rapid onset Obesity, Hypoventilation, Hypothalamic dysfunction and Autonomic Dysregulation (ROHHAD) is a syndrome named in 2007. The hallmark of the syndrome is the rapid onset obesity and dysregulation of central ventilation. There is little information about the metabolic changes that lead to the rapid onset obesity in these children. The investigators would like to study the metabolic phenotype of these children to understand the disturbances in energy balance that lead to the rapid onset obesity.
This project is a pilot study designed to investigate transcriptional regulation in breast cancer. Although the main focus of the present study will be triple negative breast cancer where all of the clinically relevant receptors - estrogen receptor (ER), progesterone receptor (PR) and herceptin (HER2) - are absent, all breast tissue biospecimens, including normal and mammary dysplasia, stored in the UAMS Tissue bank, procured from outside collaborators or purchased from commercial vendors will eventually be investigated. We will use high throughput molecular profiling techniques such as microarrays and next generation sequencing to correlate gene expression and gene expression regulation with clinical parameters such as tumor size, time to relapse and overall survival.
The primary purpose of this study is to support the development of a host response test for acute respiratory illness to identify bacterial, viral or NB/NV etiologies as compared to a clinical adjudication reference standard. Secondary objectives include: 1. Evaluate the effect of age on the performance of the HR-ARI test 2. Evaluate the effect of race/ethnicity on the performance of the HR-ARI test 3. Evaluate the effect of geography on the performance of the HR-ARI test
This clinical trial is examining the role of genetic polymorphism on the effect of clopidogrel (with or without aspirin) on platelet response in persons at high-risk for myocardial infarction or stroke due to family history of early-onset coronary artery disease.

The purpose of this study is to discover genetic changes associated with different cancers. With the information from this study the investigators hope to provide better ways to prevent, detect and treat many cancers. Many diseases can result from changes in a person's genetic material that causes cells to not work properly. Currently, researchers and doctors know some of the genetic changes that can cause disease, but they do not know all of the genetic changes that can cause disease. This project is designed to identify genetic changes that can cause cancer in humans. Specimens will be collected from a scheduled diagnostic or routine (i.e. blood draw for counts) procedure and may include samples from the tissue itself (surgery), bone marrow, blood, saliva, urine, spinal fluid, sputum, joint fluid, seminal fluid, ascites (a fluid that fills up in the abdomen), and/or pleural fluid (fluid in the lung cavity), to either confirm the diagnosis of cancer or to help to decide how best to treat cancer or other illness. Additionally archived tissue may be analyzed. Samples may be stored for future use in later experiments. The Department of Pathology at Rhode Island Hospital will store the samples. Information from the medical record, such as responses to treatments or family history of cancer, will be collected.
The specific aim of this protocol is to examine differential expression of specific mRNAs and proteins that occur when the dietary intake of zinc is acutely reduced below the dietary requirement for a period of ten days.
The overarching purpose of this study is to determine if a modified 8-week mindfulness-based intervention (with a focus on self-compassion; MBSC) or 8 weeks of 2000 IU vitamin D supplementation will reduce stress and increase self-compassion in mothers of preterm infants and beneficially modify the human milk produced, and subsequently improve infant health.
This is a prospective trial for a computation-based efficacy prediction method for anticancer target therapies. The original computational algorithm utilizes individual transcriptome data of a cancer sample and assesses changes at the level of gene expression and intracellular signaling pathways. By applying the database of known molecular targets of anticancer target drugs it allows to rank potential efficacies of target drugs.
The purpose of the study is to identify molecular markers at the level of molecular pathway activation to predict efficacy of anti-HER2 therapy with Trastuzumab.
This is a prospective, single center, clinical mechanistic pilot clinical research study. Participants will not receive any investigational agent. The investigators will examine whether children with atopic dermatitis (AD) and food allergy have a different skin barrier, microbiome, epidermal transcriptome, and epidermal lipid composition than children with AD and no food allergy and non-atopic (NA) children. Participation involves a single study visit.
Background: AD-HIES is a disease that weakens the immune system. It puts people at risk for infections, particularly Staph and Candida infections. Researchers want to test a vaccine that may help keep people from getting these infections, which would help people with AD-HIES. Objective: To test the new vaccine NDV-3A for protection against infection from the yeast Candida and the bacterium Staphylococcus aureus (Staph). Eligibility: Adults ages 18-55 who have AD-HIES Healthy volunteers ages 18-55 Design: Participants will have 6-7 study visits over 6-7 months. They will also be contacted by phone in between some visits. Participants will be screened with a medical history, physical exam, and blood and urine tests. Participants will have 2 baseline visits. They will have repeat the screening tests. They will have samples of saliva, stool, skin, mucus (oral, nasal, and/or vaginal) collected. Vaginal and stool samples are optional. Any eczema on their skin will be looked at. Participants will fill out symptom diary cards to record how they feel. Participants will have the NDV-3A vaccine injected into a muscle in the arm. Participants will return the next 2 days. They will have a physical exam. Blood will be collected. Participants will have 2 more follow-up visits at the NIH. They will have a physical exam. They will have blood, saliva, stool, skin, vaginal fluid, and/or mucus samples collected. Vaginal and stool samples are optional. Participants will be called once a month for 5 months after the vaccination. There is an optional visit about 6 weeks after the vaccination. Participants will provide a blood sample at this visit.
