Comparison of neutrophil lymphocyte ratio, platelet lymphocyte ratio, and mean platelet volume and PCR test in COVID-19 patients

Rev. Assoc. Med. Bras. (1992); 67 (supl.1), 2021
SUMMARY OBJECTIVE: The polymerase chain reaction test, used in the diagnosis of COVID-19, can be positive with delay, and thorax tomography is used for the diagnosis of the disease. We aimed to compare the relation between thorax tomography findings, PCR test results, and neutrophil lymphocyte ratio; pl...

Association between Mean Platelet Volume-to-Lymphocyte Ratio and the Presence of Apical Mural Thrombus in Post-Myocardial Infarction Patients

Abstract Background Left ventricular apical thrombus (AT) is generally associated with ischemic and non-ischemic cardiomyopathies. The thrombo-inflammatory process plays an important role in the pathophysiology of acute coronary syndromes and post-myocardial thromboembolic complications. Mean platelet ...

Volumen plaquetario medio como predictor de la mortalidad en pacientes con sepsis: revisión sistemática y metanálisis

Infectio; 24 (3), 2020
Introducción: El volumen medio plaquetario (VMP) es un biomarcador utilizado en el abordaje integral de la sepsis. Objetivo: Evaluar la asociación entre VMP con la mortalidad en pacientes con sepsis. Métodos: Se realizó una revisión sistemática de estudios observacionales en cinco bases de dat...

Effect of COVID-19 on platelet count and its indices

SUMMARY BACKGROUND Easily accessible, inexpensive, and widely used laboratory tests that demonstrate the severity of COVID-19 are important. Therefore, in this study, we aimed to investigate the relationship between mortality in COVID-19 and platelet count, Mean Platelet Volume (MPV), and platelet dist...

Assessment of inflammatory markers in otosclerosis patients

Abstract Introduction Otosclerosis is an idiopathic disease characterized by new bone formation in foci of the human otic capsule. It is more common in Caucasian populations; affecting females twice as often as males. Its etiopathogenesis has not yet been fully elucidated. Objective The aim of this stu...

The usefulness of systemic inflammatory markers as diagnostic indicators of the pathogenesis of diabetic macular edema

Arq. bras. oftalmol; 83 (4), 2020
ABSTRACT Purpose: To investigate the usefulness of systemic inflammatory markers [i.e., white blood cell and platelet counts, mean platelet volume, and their ratios] as diagnostic markers of the pathogenesis of diabetic macular edema. Methods: The study cohort included 80 diabetic macular edema patient...

Performance of a Hematological Scoring System in Predicting All-Cause Mortality in Patients with Acute Myocardial Infarction

Abstract Background: The presence of nucleated red blood cells (NRBCs) and increases in mean platelet volume (MPV) and neutrophil to lymphocyte ratio (NLR) in peripheral circulation are associated with poorer prognosis in patients with acute coronary disease. Objective: We developed a scoring system fo...
