Researchers want to better understand how injury and inflammation are caused by these exposures. They want to collect biological and environmental samples and other data. They may use the samples to measure a range of factors, like hormones, toxins, and chemicals. This will help them improve their studies.\n\nObjective:\n\nTo identify and understand how environmental exposures contribute to human disease.\n\nEligibility:\n\nHealthy adults ages 18 and older\n\nDesign:\n\nParticipants will be screened with questions about their health history, demographics, and medicines they take.\n\nParticipants may give blood, hair, stool, saliva, and\u002For urine samples. They may have a skin punch biopsy to collect skin cells. They may give fingernail or toenail clippings. They may give a sample of exhaled breath.\n\nParticipants may give a sputum sample. They will inhale a saline mist and cough mucus into a cup.\n\nParticipants may have their nasal passages brushed, scraped, or washed.\n\nParticipants may give cheek cell samples. They will swish mouthwash and spit it into a cup.\n\nParticipants who produce sperm may give samples.\n\nParticipants may have bronchoscopy to collect fluid. A saline solution will be put into their lung and then suctioned out, washing areas of the lung.\n\nParticipants may have a pelvic or transvaginal ultrasound. They may have lung function tests.\n\nParticipants may collect household dust, urine, or stool at home.\n\nParticipants will complete surveys about their health, diet, and exposures.\n\nParticipation will last for one or more study visits.\n\nParticipants may be contacted in the future to take part in other studies.",[26,27,28],"Inflammation","Normal Controls","Metabolic Disease",[30,28,26,31],"Blood Collection","Natural History","RECRUITING","2026-04-17",{"date":35,"type":36},"2026-04-20","ACTUAL",{"date":38,"type":36},"2021-11-16",{"date":40,"type":22},"2031-12-31",{"name":42,"class":43},"National Institute of Environmental Health Sciences (NIEHS)","NIH",1,{"id":46,"slug":47,"hasResults":11,"nctId":48,"briefTitle":49,"officialTitle":50,"acronym":4,"eligibilityCriteria":51,"healthyVolunteers":16,"sex":17,"minAge":18,"maxAge":52,"enrollmentInfo":53,"targetDuration":4,"studyType":55,"phases":56,"briefSummary":58,"conditions":59,"keywords":4,"overallStatus":32,"whyStopped":4,"lastUpdateSubmitDate":61,"lastUpdatePostDateStruct":62,"startDateStruct":64,"completionDateStruct":66,"leadSponsor":68,"locationsCount":44},"100464998","oxalate-and-citrate-100464998","NCT05334979","Oxalate and Citrate","Oxalate and Citrate in Humans","Inclusion Criteria:\n\nStone formers:\n\n* Age 18-70\n* History of at least one calcium-based kidney stone\n\nNon-stone formers (controls):\n\n* Age 18-70\n* No history of kidney stone\n* 24-hour urine oxalate within lab normal (\\\u003C50mg\u002Fday)\n\nExclusion Criteria:\n\n* History of primarily uric acid, cysteine, or struvite stones.\n* History of severe acid-base abnormality, very low (less than 100mg\u002Fday) or very high (greater than 1500mg\u002Fday) urine citrate.\n* Any controls or stone-forming participants who cannot stop diuretic medication or alkali supplementation for the course of the study period.\n* Non-stone formers and stone-formers with extreme levels of urine citrate will be excluded from this small initial study to reduce heterogeneity and remove focus from the extremes of citrate levels.","70 Years",{"count":54,"type":22},50,"INTERVENTIONAL",[57],"NA","This is a single-center study that aims to earn more about how two different compounds found in food, oxalate and citrate, may affect a person's chances of forming kidney stones.",[60,27],"Kidney Stone","2026-01-07",{"date":63,"type":36},"2026-01-08",{"date":65,"type":36},"2022-10-27",{"date":67,"type":22},"2026-12-01",{"name":69,"class":70},"University of Chicago","OTHER"]
