771 Clinical Trials for Various Conditions
Background: * Melanocytic nevi, or "moles," are non-cancerous growths of a type of skin cell called a melanocyte. * Large congenital melanocytic nevi (LCMN) are a special type of mole that begins to grow before birth and is larger than moles that develop after birth. * Determining how melanocytes in moles and LCMNs differ from normal melanocytes may increase the ability to predict whether a mole will give rise to a melanoma (a type of skin cancer) Objectives: * To understand how melanomas develop, by studying moles, LCMNs, and pigmented skin lesions that are suspicious for melanoma * To develop better criteria for diagnosing melanoma, particularly by using a device called a digital dermatoscope (a special camera, connected to a computer, that takes pictures of moles when they are magnified and illuminated) Eligibility: * Children 5 years old or older with an LCMN * Adults 18 years old or older with 100 or more moles larger than 2 mm in diameter and at least one 4 mm or more * Adults 18 years old or older with a pigmented lesion suspicious for melanoma Design: * Patients' personal and family health history is obtained. * Patients are examined by investigative team doctors, and several lesions are examined with a dermatoscope. * Additional photographs of part or all of the skin surface may be taken. * Some lesions may be biopsied. * Additional tests or examinations may be recommended. * Patients are followed periodically for skin or physical examinations, photography, laboratory and imaging evaluations, and possible skin biopsies. * Children may undergo brain magnetic resonance imaging (MRI)
Citrulline dietary supplements are of interest for improving cardiovascular and exercise performance. The health benefits of citrulline are attributable to its ability to increase arginine levels in the body through the intestinal-renal arginine conversion pathway. From a dietary supplementation standpoint, citrulline offers advantages over arginine due to its reduced first-pass metabolism and ready conversion to arginine within the body. While L-citrulline is the most widely used citrulline dietary supplement, additional salt forms such as citrulline maleate and citrulline HCl may provide improvements in the delivery of arginine to the body. The present study compared the single-dose pharmacokinetics of L-citrulline and citrulline HCl formulations in healthy human subjects. A total of 17 subjects were randomly assigned to groups receiving either 6 g of L-citrulline, 6 g of citrulline HCl or 2 g of citrulline HCl. The resulting increases in citrulline and arginine in plasma and urine samples were determined using liquid chromatography-multiple reaction monitoring mass spectrometry (LC-MRM/MS). All citrulline dietary supplements examined produced time-dependent increases in plasma citrulline and arginine. Both maximal plasma concentration (Cmax) and area under the plasma vs time curve (AUC) for citrulline were modestly reduced in the 6 g citrulline HCl treatment group, the resulting arginine Cmax and AUCs were similar for both L-citrulline and citrulline HCl at the 6 g dose. While the 2 g dose of citrulline HCl had reduced Cmax and AUC values compared to 6 g doses, the time to reach peak levels of arginine were significantly shorter. Furthermore, examination of the relative arginine bioavailability achieved with the 6 g and 2 g citrulline HCl compared to the 6 g L-citrulline was approximately 120% and 215%, respectively, consistent with an improved citrulline to arginine conversion efficiency with the citrulline HCl formulations.

The Epilepsy-Dyskinesia Study aims to advance the understanding of the clinical and molecular spectrum of epilepsy-dyskinesia syndromes, monogenic diseases that cause both movement disorders and epilepsy. Addressing challenges in rare disease research -such as small, geographically dispersed patient populations and a lack of standardized protocols- the study employs a multinational retrospective survey endorsed by the International Parkinson and Movement Disorder Society. This survey seeks to collect comprehensive data on clinical features, disease progression, age of onset, genetic variants, and concurrent neurological conditions, standardizing data collection across countries to provide a unified understanding of these conditions. Through retrospective review and molecular data analysis, the study aims to identify patterns and correlations between movement and seizure disorders, uncovering genotype-phenotype relationships. The initiative\'s goals are to enhance understanding of epilepsy-dyskinesia syndromes, inform precision medicine approaches, and foster international collaboration.
Investigators will employ serial assessments of tissue biopsy and additional biomarkers that reflect burden of disease and predict treatment response. Patients enrolled on this study will be given the option to provide biological samples before, during, and after treatment, as well as functional outcomes of treatment response. These samples will be utilized to develop and validate prognostic and predictive biomarkers for patients undergoing targeted therapy, immunotherapy, surgery, chemotherapy, and/or radiotherapy.

The hypothesis of the trial is that synthetic long peptide personalized cancer vaccines will be safe and capable of generating measurable neoantigen-specific T-cell responses enabling ctDNA clearance. The personalized cancer vaccines are composed of synthetic long peptides corresponding to prioritized cancer neoantigens and will be co-administered with poly-ICLC.
Hidradenitis suppurativa (HS) and atopic dermatitis (AD) are chronic inflammatory skin diseases that lead to the development of skin lesions and symptoms such as pain and discomfort. The purpose of this study is to assess molecular changes in adult participants with moderate to severe HS or with moderate to severe AD. Lutikizumab (ABT-981) is an investigational drug being developed for the treatment of HS and AD. This study will consist of 2 sub-studies: Sub-Study 1 moderate to severe hidradenitis suppurativa and Sub-Study 2 moderate to severe atopic dermatitis. Approximate 60 participants will be enrolled in the study at approximately 2 sites in the US. In Sub-Study 1 HS participants will receive subcutaneous (SC) injections of lutikizumab for up to week 15 with a 70-day follow-up period. In Sub-Study 2 AD, participants will receive subcutaneous (SC) injections of lutikizumab for up to week 14 with a 70-day follow-up period. The study duration for Sub-Studies 1 and 2 is expected to last up to 30 weeks. Participants in Sub-Study 1 (HS) who complete Week 16 and showed a therapeutic benefit to lutikizumab, as confirmed by the investigator, will have the option to enter an open-label long-term extension (LTE) to continue to receive lutikizumab for up to an additional 140 weeks, followed by a 70-day follow-up period. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic and may require frequent medical assessments, blood tests, and biomarker collections.

The goal of this observational study is to learn about further wheezing in infants with RSV infection.. The main question it aims to answer is: If infant factors, the infant immune response in the nose and the bacteria that reside in the nose at the time of primary RSV infection can predict/classify infants with recurrent wheezing during the following year. A secondary aim is to identify infant immune response factors in the nose and patterns of bacteria in the nose during primary RSV infection that may help us understand why recurrent wheezing occurs. Researchers will compare infants with repeated episodes of wheezing to infants who do not have further wheezing. Participants will be full term infants with their first RSV infection. We will collect information on the pregnancy and birth history as well as the signs and symptoms of RSV infection. Two nasal swabs and a nasal wash will be collected from the infants. Six weeks following the RSV infection we will begin contact with the families biweekly to determine if the infant has recurrent wheezing confirmed by a medical provider. Follow-up will continue for approximately 1 year, through a second winter season.

Fitness is one of the best predictors for heart and brain disease. To increase ones fitness, the American Heart Association (AHA) says to exercise at least 150 minutes per week or 75 minutes per week if really hard. These exercise guides are pretty effective, however not everyone will get the same results. What individuals do outside of the exercise bout can influence the effectiveness of exercise. One of these factors is our time sitting, which has caused the phrase "sitting is the new smoking". Other studies have said that the metabolic benefits of exercise are decreased when you exercise after a few days of low activity (less than 5,000 steps per day). This is important in that exercise may not be able to fully offset these times of inactivity. However, these studies were only looking at different fats in the blood. As exercise increases fat burn up to 10 times in the muscle, more research is needed to understand how inactivity affects the muscle during exercise and after exercise. This study will help answer two questions: 1) How does a day of sitting a lot affect the muscle's ability to respond to exercise? and 2) How does a day of sitting a lot affect carbohydrate and fat burn during and after a bout of exercise? The investigators will answer these questions by having people complete one day of inactivity (less than 5,000 steps) or normal activity (more than 8,500 steps). Subjects will then come in the next day to bike somewhat hard for 1 hour. The investigators will take blood samples before, during, and after exercise to measure energy sources. The investigators will also collect pieces of skeletal muscle before and after exercise to see how the muscle responded to exercise. This study is significant for the publication of exercise guidelines to minimize risk of heart and metabolic diseases.
This study will explore potential links between atopic dermatitis and food allergy. This information will be useful to determine atopic dermatitis and food allergy share unique biochemical or genetic identifiers useful for diagnosing and treatments in the future. This is a mechanistic study consisting of obtaining blood and skin samples from participants at baseline. Individuals may also undergo a clinically indicated oral food challenge and have blood and skin samples collected at various times during the oral food challenge. This study will create a molecular map of the pathology of atopic dermatitis and food allergy. This information will be deployed to evaluate the hypothesis that atopic dermatitis and food allergy share unique genetic transcriptional signals in which the study team can then further analyze pathological pathways and cell types.
Currently, there is no clinically available genetic-based treatment for RAI1 (Retinoic Acid-Induced 1) -related disorders other than symptomatic management and there are no established clinical or molecular biomarkers that could be used as measures for the efficacy of therapy in future treatment studies. Biomarkers are measures of what is happening inside the body, shown by the results of laboratory, imaging or other tests. Biomarkers can help doctors and scientists diagnose diseases and health conditions, monitor responses to treatment and see how a person's disease or health condition changes over time. The goal of this observational and laboratory study is to develop clinical, neurophysiology and molecular biomarkers in RAI1-related disorders. The main question\[s\] it aims to answer are: * to characterize the disease features more precisely and analyze the differentiating and overlapping features of RAI1-related disorders (Smith-Magenis syndrome and Potocki-Lupski Syndrome) * to identify clinical, neurophysiology, and laboratory biomarkers that differentiate RAI1-related disorders one from another. Participants will have to complete: * a clinical examination * a blood draw * a skin biopsy (optional) * a sleep study Researchers will compare patients' blood to control group's blood for biomarker studies.
