(2-Heremans-schmid glycoprotein (fetuin A) downregulation and its utility in inflammatory bowel disease
(2017)AIM: To investigate the impact of inflammatory bowel disease (IBD) on α2-Heremans-Schmid Glycoprotein (AHSG/fetuin A) and potential associations with disease and patient characteristics. METHODS: AHSG serum levels were ... -
99mTc sestamibi as a prognostic factor of response to first-line therapy and outcome in patients with malignant lymphoma
(2013)INTRODUCTION: Resistance to chemotherapy poses a major problem in cancer patients. Although of multifactorial origin, some of the implicated mechanisms also interfere with Tc-MIBI uptake and retention in cancer cells. The ... -
Accuracy and Calibration of Computational Approaches for Inpatient Mortality Predictive Modeling
(2016)Electronic Health Record (EHR) data can be a key resource for decision-making support in clinical practice in the "big data" era. The complete database from early 2012 to late 2015 involving hospital admissions to Inselspital ... -
Accuracy of the sleep clinical record for the diagnosis of pediatric moderate-to-severe obstructive sleep apnea syndrome
(2022)Purpose: The sleep clinical record (SCR) has been used to diagnose obstructive sleep apnea syndrome (OSAS) in children when access to polysomnography (PSG) is limited. Our aim was to determine the best SCR score that could ... -
Anatomical Differences Between Intact and Ruptured Large Abdominal Aortic Aneurysms
(2020)Purpose: To compare different anatomical characteristics between intact and ruptured large abdominal aortic aneurysms (rAAA >80 mm) with the goal of refining the process of estimating rupture risk. Materials and Methods: ... -
Anti-MCV antibodies predict radiographic progression in Greek patients with very early (<3 months duration) rheumatoid arthritis
(2017)This study aimed to assess the diagnostic and prognostic value of anti-mutated citrullinated vimentin (MCV) antibodies in very early rheumatoid arthritis (VERA) and in established rheumatoid arthritis (RA). Seventy-one ... -
Assessing multiple-group diagnostic problems with multi-dimensional receiver operating characteristic surfaces: Application to proton MR Spectroscopy (MRS) in HIV-related neurological injury
(2008)We present the multi-dimensional Receiver Operating Characteristic (ROC) surface, a plot of the true classification rates of tests based on levels of biological markers, for multi-group discrimination, as an extension of ... -
The association between retinopathy of prematurity and ocular growth
(2019)PURPOSE. The purpose of this study was to prospectively investigate the association between retinopathy of prematurity (ROP) and ocular growth in premature infants during the earliest weeks of life. METHODS. Premature ... -
ASTRAL-R score predicts non-recanalisation after intravenous thrombolysis in acute ischaemic stroke
(2015)Intravenous thrombolysis (IVT) as treatment in acute ischaemic strokes may be insufficient to achieve recanalisation in certain patients. Predicting probability of non-recanalisation after IVT may have the potential to ... -
Bootstrap-based testing approaches for the assessment of the diagnostic accuracy of biomarkers subject to a limit of detection
(2019)Assessment of the diagnostic accuracy of biomarkers through receiver operating characteristic curve analysis frequently involves a limit of detection imposed by the laboratory analytical system precision. As a consequence, ... -
Breast Cancer Classification on Multiparametric MRI – Increased Performance of Boosting Ensemble Methods
(2022)Introduction: This study aims to assess the utility of Boosting ensemble classification methods for increasing the diagnostic performance of multiparametric Magnetic Resonance Imaging (mpMRI) radiomic models, in differentiating ... -
Can bioelectrical impedance analysis and BMI be a prognostic tool in head and neck cancer patients? A review of the evidence
(2020)Background: Malnutrition can significantly affect disease progression and patient survival. The efficiency of weight loss and bioimpedance analysis (BIA)-derived measures in the evaluation of malnutrition, and disease ... -
Checking for voice disorders without clinical intervention: The Greek and global VHI thresholds for voice disordered patients
(2019)Voice disorders often remain undiagnosed. Many self-perceived questionnaires exist for various medical conditions. Here, we used the Greek Voice Handicap Index (VHI) to address the aforementioned problem. Everyone can fill ... -
COMP serum levels: A new non-invasive biomarker of liver fibrosis in patients with chronic viral hepatitis
(2017)Background & aims Recently we have shown that cartilage oligomeric matrix protein (COMP), a fibrillar collagen assembly regulator, is strongly associated with cirrhosis and hepatocellular carcinoma progression. Therefore, ... -
Comparison of 3D ultrasound, 2D ultrasound and 3D Doppler in the diagnosis of endometrial carcinoma in patients with uterine bleeding: A systematic review and meta-analysis
(2022)Endometrial cancer is a common malignancy affecting women worldwide. Usually, it clinically manifests with uterine bleeding, although identical clinical manifestations occur in benign conditions as well, with several ... -
Computer-based automated estimation of breast vascularity and correlation with breast cancer in DCE-MRI images
(2017)Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) with gadolinium constitutes one of the most promising protocols for boosting up the sensitivity in breast cancer detection. The aim of this study was twofold: ... -
Confidence intervals for differences between volumes under receiver operating characteristic surfaces (VUS) and generalized Youden indices (GYIs)
(2018)This article explores both existing and new methods for the construction of confidence intervals for differences of indices of diagnostic accuracy of competing pairs of biomarkers in three-class classification problems and ... -
Construction of joint confidence regions for the optimal true class fractions of Receiver Operating Characteristic (ROC) surfaces and manifolds
(2017)The three-class approach is used for progressive disorders when clinicians and researchers want to diagnose or classify subjects as members of one of three ordered categories based on a continuous diagnostic marker. The ... -
