Filter by:The 2020 NIMH Strategic Plan for Research calls for investigations targeting neurobiology of mental illness across the lifespan. Growing evidence suggests that lifespan neurobiology of schizophrenia (SZ) incorporates two distinct dimensions: aging and disease course. However, their clinical correlates, associated biomarker trajectories, and implications for treatment are unknown. This study will investigate differential aspects of SZ neurobiology captured by aging and disease course, in order to develop specific biomarkers which may offer actionable targets for SZ stage-dependent intervention. The study is predicated on a novel mechanistic Model of SZ Trajectories across the Adult Lifespan, positing distinct biological fingerprints within the anterior limbic system for aging and disease course in SZ: (1) alterations in the circuit's function and structure that occur earlier in the lifespan and are larger in magnitude than the alterations expected with normal aging (accelerated aging dimension); and (2) regionally-specific anterior limbic "hyperactivity" in early SZ, with a subsequent transformation into "hypoactivity" in advanced SZ (disease course dimension). In a sample of SZ and matched healthy controls (n=168, 84/group) aged 18-75 years the investigators will ascertain a broad panel of biomarkers [via multimodal brain imaging: optimized 1H-MRS, high-resolution task-based fMRI, perfusion (Vascular Space Occupancy) and structural MRI], along with comprehensive cognitive and clinical assessments. All measures will be acquired at baseline and repeated at 2-year longitudinal follow-up. Using cutting-edge computational approaches, the study will examine (i) effects of aging and SZ course on anterior limbic system biomarkers; (ii) lifespan trajectories for different biomarkers; (iii) patterns of limbic system biomarkers in age- and SZ course-based subgroups (e.g., Younger vs. Older, Early-Course vs. Advanced SZ), as well as in data-driven subgroups (e.g., those with vs. without accelerated aging profiles); and (iv) associations between biomarkers and cognitive and clinical outcomes. This research will advance the field by providing novel biomarkers that capture unique neurobiological contributions of aging and disease course in SZ, and will motivate future studies on SZ mechanisms across the lifespan and development of precision treatments.
Diabetic nephropathy (DN) is one of the major microvascular complications associated with diabetic patients, and also the major global cause of chronic kidney disease and end-stage renal disease (ESRD). Albuminuria and estimated glomerular filtration rate (eGFR) are currently recognized clinical indicators for early diagnosis of DN, however, the sensitivity and specificity are unsatisfactory. The early identification and treatment of DKD are conducive to lowering the risk of kidney damage by as much as 50%. Therefore, it is particularly critical to find new biomarkers to reflect the potential DKD lesions in the clinical silent period earlier and more accurately. Therefore, this study intends to analyze the differentially expressed lipids in early DKD, T2DM and healthy adults by mass spectrometry, and verify the related results by larger samples, so as to screen out early markers of DKD and achieve the ultimate goal of clinical application.
This multicenter prospective observational and exploratory study aims to develop and validate a novel multi-omics-based computational method for neoantigen prediction in non-small cell lung cancer (NSCLC), and discover biomarkers for evaluation of PD-1/PD-L1 inhibitor's efficacy in patients of advanced NSCLC.
Collect blood from patients admitted for coronary angiography to tubes with heparin, centrifuge and collect plasma. This will be frozen at -80C. Sent to the Lipotype laboratory, Dresden, Germany, for the detection and quantification of compounds derived from oxidized LDL cholesterol (cholesterol hemi-esters).
Multiple Sclerosis (MS) characterized by demyelination and axonal degeneration is a chronic inflammatory disease of the central nervous system (CNS). Recent studies have shown that dysregulated miRNAs alter immune responses, so they may have roles basis on various genetic diseases such as MS and may be potential targets for biomarkers and new therapeutic approaches. In this study, we evaluated the dysregulation of miRNA expression levels at MS and MS stages. We also discussed the potential of these miRNAs to be biomarkers and/or therapeutic targets in MS.
Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and in infected patients, it produces symptoms which range from completely asymptomatic to those expressing severe illness. Early recognition of those developing severe manifestations allows for rapid and appropriate intervention, including admission to intensive care unit and intensive care therapy, such as mechanical ventilation. A current problem is that only limited data exist predicting the clinical course of COVID-19. This study will determine whether non-invasive urinalysis is useful in assessing and predicting the severity or clinical course of patients with COVID-19.
The investigators design a prospective clinical study to explore the efficacy and safety of apatinib plus camrelizumab in pretreated patients with advanced biliary tract malignant tumors and to analyze potential biomarkers of therapeutic response.
Chronic wounds represent a growing challenge in medical care. Part 1: The aim of this part of the study was to collect wound swabs and to answer the question whether the rapid diagnostic tool using enzyme activities can display an infection prematurely. This means that an increased enzyme activity (especially MPO, NHE, LYS, gelatinase, pH) measured overed 3 days, would indicate a change in the wound bed (infection, Inflammation) earlier than the regularly performed clinical assessment. Part 2: The aim of this part of the study was to evaluate (I) the possibility of wound fluid acquisition by means of an "additional collector" during ongoing NPWT and to answer if (II) this secretion can be biochemically analyzed for enzyme activities in order to be able to detect a change in the wound situation at an early stage.
To establish risk rating criteria of biological protein marker, determine the role and consistency of aGVHD biomarkers in aGVHD diagnosis and aGVHD prognosis, and evaluate the the impact on non-relapse mortality and relapse and disease free survival, the multicenter study on aGVHD biomarkers detection in the patients underwent allogeneic hematopoietic stem cell transplantation was performed.
The purpose of this study is to validate the screening protocol to study risk factors of exercise-induced bronchoconstriction (EIB) obtained in our previous study in high-school elite athletes (NCT03587675), in recreational young athletes who perform intense physical exercise.
