Optimal diagnostic tests for sporadic Creutzfeldt-Jakob disease based on support vector machine classification of RT-QuIC data
In this work we study numerical construction of optimal clinical diagnostic tests for detecting sporadic Creutzfeldt-Jakob disease (sCJD). A cerebrospinal fluid sample (CSF) from a suspected sCJD patient is subjected to a process which initiates the aggregation of a protein present only in cases of sCJD. This aggregation is indirectly observed in real-time at regular intervals, so that a longit...
متن کاملClinical findings and diagnostic tests in the MV2 subtype of sporadic CJD.
Atypical clinical course and low sensitivity of established diagnostic tests are the main diagnostic problems in the MV2 subtype of sporadic Creutzfeldt-Jakob disease (sCJD). Clinical symptoms and signs, MRI, EEG and biochemical CSF markers were studied in 26 patients. Histological findings were semiquantitatively evaluated. Compared with typical sCJD, the disease duration was prolonged (median...
متن کاملRapid and Sensitive RT-QuIC Detection of Human Creutzfeldt-Jakob Disease Using Cerebrospinal Fluid
UNLABELLED Fast, definitive diagnosis of Creutzfeldt-Jakob disease (CJD) is important in assessing patient care options and transmission risks. Real-time quaking-induced conversion (RT-QuIC) assays of cerebrospinal fluid (CSF) and nasal-brushing specimens are valuable in distinguishing CJD from non-CJD conditions but have required 2.5 to 5 days. Here, an improved RT-QuIC assay is described whic...
متن کاملExtended and direct evaluation of RT‐QuIC assays for Creutzfeldt‐Jakob disease diagnosis
Real-Time Quaking-Induced Conversion (RT-QuIC) testing of human cerebrospinal fluid (CSF) is highly sensitive and specific in discriminating sporadic CJD patients from those without prion disease. Here, using CSF samples from 113 CJD and 64 non-prion disease patients, we provide the first direct and concurrent comparison of our improved RT-QuIC assay to our previous assay, which is similar to t...
متن کاملDiagnostic Utility of miRNAs in Cancer
Cancer is the one of most prevalent and leading causes of death in the world. Current ad­vancements in technology improve the understanding of the pathogenesis and pathology of cancers. But, due to enlarging mortality rates, poor prognosis, and lacunae in clinical early predictive biomarkers provide an important momentum to investigate novel early diagnos­tic/prognostic markers and spec...
