High-sensitivity cardiac troponin T and copeptin assays to improve diagnostic accuracy of exercise stress test in patients with suspected coronary artery disease [PDF]

, 2014
Background: The average diagnostic sensitivity of exercise stress tests (ESTs) is lower than that of other non-invasive cardiac stress tests. The aim of the study was to examine whether high-sensitivity cardiac troponin T (hs-cTnT) or copeptin ...

The Hippocampal Film Editor: Sensitivity and Specificity to Event Boundaries in Continuous Experience

Journal of Neuroscience, 2018
The function of the human hippocampus is normally investigated by experimental manipulation of discrete events. Less is known about what triggers hippocampal activity during more naturalistic, continuous experience.

A33 shows similar sensitivity to but is more specific than CDX2 as an immunomarker of colorectal carcinoma [PDF]

, 2017
Aims: CDX2 is widely used as a sensitive and specific immunomarker for colorectal carcinoma (CRC) but neither this sensitivity nor specificity is absolute. This study is the first known comparison of CDX1 and A33 against CDX2 as immunomarkers for CRC.

Novel DNA methylation biomarkers show high sensitivity and specificity for blood-based detection of colorectal cancer—a clinical biomarker discovery and validation study

Clinical Epigenetics, 2019
Early detection plays an essential role to reduce colorectal cancer (CRC) mortality. While current screening methods suffer from poor compliance, liquid biopsy-based strategies for cancer detection is rapidly gaining promise.

The sensitivity and specificity of platelet autoantibody testing in immune thrombocytopenia: a systematic review and meta‐analysis of a diagnostic test

Journal of Thrombosis and Haemostasis, 2019
Essentials The diagnosis of ITP is based on a platelet count < 100 × 109 L−1 and exclusion of other causes. There are no standard tests or biomarkers to diagnose ITP. The sensitivity of platelet autoantibody testing is low (53%). The specificity is high (

Determination of a cutoff for noise sensitivity: Psychometric evaluation of the Turkish Noise Sensitivity Questionnaire (Tr-NoiSeQ)

Noise and Health, 2022
Context: There is a need for a clear cutoff to use noise sensitivity (NS) scale as a prediagnostic tool in research and clinical use. Aims: Noise sensitivity questionnaire (NoiSeQ) was adapted into Turkish language (Tr-NoiSeQ); validity and reliability ...
