Alternations in miR-155 and miR-200 serum levels can serve as biomarkers for COVID-19 in the post-mass vaccination era.

Background: Mass vaccination and natural immunity reduced the severity of COVID-19 cases. SARS-CoV-2 ongoing genome variations imply the use of confirmatory serologic biomarkers besides PCR for reliable diagnosis. MicroRNA molecules are intrinsic components of the innate immune system.

SNP (A > G - rs13057211) but not GT(n) polymorphism in HMOX-1 promotor gene is associated with COVID-19 mortality.

Introduction: COVID-19 causes severe inflammatory respiratory distress syndrome. The global pandemic caused millions of cases of morbidity and mortality worldwide. Patients may present with variable symptoms including dyspnea, fever, and GIT manifestations.

Efficacy and safety of inhaled heparin in asthmatic and chronic obstructive pulmonary disease patients: a systematic review and a meta-analysis.

Asthma and chronic obstructive pulmonary disease (COPD) are prevalent chronic respiratory disorders that cause significant morbidity and mortality. Some studies evaluated the use of inhaled unfractionated heparin (UFH) in the treatment of asthma and COPD. We aimed to synthesize the available evidence for the efficacy and safety of inhaled heparin in improving lung functions among asthmatic and COPD patients.

HOXA9 gene promotor methylation and copy number variation of SOX2 and HV2 genes in cell free DNA: A potential diagnostic panel for non-small cell lung cancer.

Background: Most cases of lung cancer are diagnosed at advanced stage. Detection of genetic and epigenetic markers in cell-free DNA (cfDNA) is a promising tool for the diagnosis of lung cancer at an early stage. The aim of this study was to identify non-invasive diagnostic markers in cell free DNA (cfDNA) for non-small cell lung cancer (NSCLC) as it is the most common type of lung cancer.

Echocardiographic assessment of the right ventricle and its correlation with patient outcome in acute respiratory distress syndrome.

Introduction: Acute respiratory distress syndrome (ARDS) is a life-threatening chest disease associated with a poor outcome and increased mortality. It may lead to pulmonary hypertension and, eventually, right ventricular failure. These changes can be investigated by transthoracic echocardiography (TTE) which is considered a non-invasive and cost-effective modality.
