Compartmental Inflammation in Mechanically Ventilated Patients With COVID-19
COVID-19Respiratory FailureThe aim of the present study is to examine the inflammatory response in the pulmonary compartment and blood of critically ill patients admitted to the ICU with COVID-19.
Immune Correlates of Cardiac Structure and Function
Perinatal HIV InfectionCardiac Fibrosis1 moreThe purpose of this study is to determine the occurrence of scarring of the heart (cardiac fibrosis) and inflammation in those with perinatally acquired Human Immunodeficiency Virus (HIV) infection compared to people not infected with HIV. The information learned from this research may help the investigator to better understand the link between cardiac fibrosis and cardiac dysfunction and inflammation in those with perinatally acquired HIV infection compared to the uninfected. Participants will have a blood sample, complete a patient questionnaire, and have a Magnetic resonance imaging (MRI) and ultrasound of the heart. Researchers will review the medical record and past medical history, for information about your heart function and overall health. Research samples and data from this study will be stored indefinitely and used for other research. There are risks to participate in this study and those risks include side effects from the contrast agent used for the MRI scan, (such as headache and injection site pain), and risks from blood sampling.
Zinc Supplementation and Cardiovascular Risk in HIV
HIVInflammationThe purpose of this pilot study is to determine whether zinc supplementation significantly affects immune activation in HIV-infected subjects.
Preeclampsia Research on Vitamin D, Inflammation, & Depression
Pre-EclampsiaDepression2 moreThis study is designed to comprehensively investigate the anti-inflammatory role of vitamin D in reproductive aged women, and its association with preeclampsia and depression. Findings will have substantial impact providing new information implicated in the development of preeclampsia (a condition that may include hypertension, tissue swelling caused by excessive fluid, and kidney stress) and postpartum depression (after birth). Additionally, the study is designed to understand how early mental health screening and evaluation can help pregnant women reduce their risk of developing postpartum depression. Testing the acceptability and effectiveness of this mental health screening, education and referral program at Cedars-Sinai Medical Center will provide valuable patient centered qualitative and quantitative data that can be used in future services planning. The study will enroll up to 200 pregnant women (in third trimester of pregnancy) in total.
Impact of Humira® Therapy on Ocular Inflammation, Selected Health Care Resource Utilization and...
UveitisThis study aims at evaluating real life effectiveness of originator adalimumab (Humira®) participants with active non-infectious intermediate, posterior and panuveitis (NIIPPU) despite high-dose corticosteroid therapy; including effect on ocular inflammation, health-related quality of life, health resource utilization, work ability and medication burden, as well as describe the characteristics of NIIPPU participants treated with Humira® in the real-life setting.
Effect of Inflammation on Pharmacokinetics of Posaconazole
MycosesPosaconazole plasma concentration and inflammatory markers will be determined in all samples available from routine analysis.
Study on Immunopathogenesis in HIV and Hepatitis C Coinfection
HIV InfectionHepatitis C Infection2 moreLiver-related death is the leading cause of mortality in HIV-infected individuals with CD4+ cell counts over 200, and hepatitis C virus (HCV) infection is the greatest risk for liver-related mortality in HIV-positive patients. Compared to HCV monoinfected individuals, patients with HIV and HCV coinfection experience accelerated progression of liver fibrosis, which can lead to higher incidence of cirrhosis, end stage liver disease (ESLD), and death. Changes in CD8+ T-cell activation, inflammatory cytokines, and serum markers of tissue injury may offer an immunologic platform to determine factors associated with progressive liver fibrosis in coinfected patients. In this cross-sectional study we will evaluate whether HIV and HCV coinfection patients with well-controlled HIV infection who have an undetectable viral load exhibit abnormal levels of inflammation and immune activation, potentially contributing to advanced liver fibrosis. Comparative groups include coinfected patients successfully treated for hepatitis C, or who have absence of hepatitis C viremia through spontaneous clearance, hepatitis C monoinfected patients, and HIV-positive patients with well-controlled HIV infection without hepatitis C. Liver fibrosis will be measured by non-invasive methods. The primary objectives of this study are: To determine if there are differences in markers of inflammation and immune activation in subsets of patients with HIV, hepatitis C, and HIV and hepatitis C coinfection. To assess the stage of liver fibrosis using non-invasive methods in subsets of patients with hepatitis C and HIV and hepatitis C coinfection and compare the degree of liver fibrosis with levels of inflammation and immune activation.
Pharmacokinetics of Understudied Drugs Administered to Children Per Standard of Care
AdenovirusAnesthesia57 moreUnderstudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).
pCLE For the Diagnosis Of Cancer in Unknown Bile Duct Stricture
CholangiocarcinomaBile Duct InflammationThis study will collect data from patients undergoing an ERCP procedure with probe-based Confocal Laser Endomicroscopy for suspicion of bile duct cancer. the objective is to evaluate the diagnostic performance of pCLE for the diagnosis of indeterminate biliary stricture when associated with other diagnostic information (standard ERCP and tissue sampling).
Effects of Increased, Egg-Based Protein Intake on Muscle Composition,
Muscle CompositionSarcopenia2 moreThis study is designed to assess the effect of a diet-controlled nutrition program utilizing an egg-based higher protein diet on muscle composition and size, and indices of metabolic health and markers of systemic inflammation in older men and women who are slightly overweight.
