Beat-to-beat variability of P-wave in patients suffering from atrial fibrillation.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
The aim of this paper was to analyze the P-wave variability over time in patients suffering from Atrial Fibrillation (AF). Behind some time-domain and morphological features of the P-wave template, two novel indexes of P-wave variability have been es...

Anti-Desmoglein 1 and 3 Autoantibody Levels in Endemic Pemphigus Foliaceus and Pemphigus Vulgaris from Brazil.

Clinical laboratory
BACKGROUND: Pemphigus is a group of autoimmune blistering diseases of which the major forms are pemphigus foliaceus (PF) and vulgaris (PV). In Brazil, PF occurs in an endemic form also known as fogo selvagem. The main autoantibody in PF is against de...

Discriminative analysis of schizophrenia using support vector machine and recursive feature elimination on structural MRI images.

Medicine
Structural abnormalities in schizophrenia (SZ) patients have been well documented with structural magnetic resonance imaging (MRI) data using voxel-based morphometry (VBM) and region of interest (ROI) analyses. However, these analyses can only detect...

Accuracy of machine learning classifiers using bilateral data from a Scheimpflug camera for identifying eyes with preclinical signs of keratoconus.

Journal of cataract and refractive surgery
PURPOSE: To describe the topographic and tomographic characteristics of normal fellow eyes of unilateral keratoconus cases and to evaluate the accuracy of machine learning classifiers in discriminating healthy corneas from the normal fellow corneas.

Quantitative assessment of hand motor function in cervical spinal disorder patients using target tracking tests.

Journal of rehabilitation research and development
Cervical spondylotic myelopathy (CSM) is a chronic spinal disorder in the neck region. Its prevalence is growing rapidly in developed nations, creating a need for an objective assessment tool. This article introduces a system for quantifying hand mot...

Diagnostic value of CA 19-9 in pregnancies complicated by spinal neural tube defects: a preliminary study.

Ginekologia polska
OBJECTIVES: Various physiological and pathological conditions can induce significant variations in plasma concentrations of tumor markers, such as CA 19-9, which is present in the serum and amniotic fluid of pregnant women. Herein, we aimed to determ...

Evaluation of Machine Learning Algorithm Utilization for Lung Cancer Classification Based on Gene Expression Levels.

Asian Pacific journal of cancer prevention : APJCP
BACKGROUND: Lung cancer remains one of the most common cancers in the world, both in terms of new cases (about 13% of total per year) and deaths (nearly one cancer death in five), because of the high case fatality. Errors in lung cancer type or malig...

GESTATIONAL DIABETES MELLITUS SEEMS TO BE ASSOCIATED WITH INFLAMMATION.

Acta clinica Croatica
The aim of this study was to investigate whether gestational diabetes mellitus (GDM) is associated with inflammation by comparing serum levels of human chitinase-3-like pro- tein 1 (YKL-40), neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte r...
