Impact of Toll-like receptor 2 (rs5743708) gene polymorphism in pediatric pneumonia: risk and severity.

Pediatric pneumonia is a common respiratory infection that affects children and is thought to be a major source of mortality and morbidity worldwide, particularly in low- and middle-income nations. Toll-like receptor2 (TLR2) is an important receptor involved in the recognition of bacterial pathogens and the activation of the immune response. Genetic variability in TLR2 may partially explain individual differences in susceptibility to infections.

Diaphragmatic strengthening exercises for patients with post COVID-19 condition after mild-to-moderate acute COVID-19 infection: a randomized controlled study.

Objective: To assess the clinical effects of incentive spirometry (IS) and diaphragmatic breathing (DB) in patients with post COVID-19 condition and diaphragmatic dysfunction as compared with the standard care alone.

Methods: The present longitudinal randomized study included 60 patients with post COVID-19 condition and diaphragmatic dysfunction. Patients were equally randomized to receive standard care plus IS (G1), standard care plus DB (G2) or standard care alone (G3) for 8 weeks.

Impact of miR-155 rs767649 Polymorphism on Rheumatoid Arthritis Activity in Egyptian Patients.

Background: Rheumatoid arthritis (RA) is a chronic inflammatory condition that impacts not only the musculoskeletal system but also various other systems in the body, including the cutaneous, ocular, respiratory, cardiovascular, and circulatory systems. MicroRNAs (miRNAs) are a class of naturally occurring and highly conserved transcripts that primarily function in the regulation of gene expression. They accomplish this by facilitating the degradation of messenger RNA (mRNA) or by repressing mRNA translation.

Determination of immunological biomarkers in sarcoidosis and their relation to disease activity.

Sarcoidosis is a multisystem granulomatous disease of unknown origin. Ninety percent of patients with sarcoidosis have lung involvement. The onset can be acute or non-acute and the severity of sarcoidosis ranges widely from asymptomatic patients with accidental radiographic findings to patients with severe organ involvement.

Bacterial Species and Inflammatory Cell Variability in Respiratory Tracts of Patients with Chronic Obstructive Pulmonary Disease Exacerbation: A Multicentric Study.

Background And Aim: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) has profound effects on disease progression and patients' quality of life. Emerging evidence suggests an association between alterations in the respiratory microbiome flora species and airway inflammation in patients with AECOPD. The present study aimed to describe the inflammatory cells and bacterial microbiome distributions in respiratory tract in Egyptian patients with AECOPD.

The Influence of Smoking on Renal Functions Among Apparently Healthy Smokers.

Background: Cigarette smoking is an important modifiable risk factor in kidney disease progression. Although long-term smoking has been associated with chronic kidney disease (CKD), its effect on kidney function in early stages has not been clarified.

Objective: To detect the early effects of smoking either active or passive on kidney functions.
