Memory T Cells Discrepancies in COVID-19 Patients.

The immune response implicated in Coronavirus disease 2019 (COVID-19) pathogenesis remains to be fully understood. The present study aimed to clarify the alterations in CD4 and CD8 memory T cells' compartments in SARS-CoV-2-infected patients, with an emphasis on various comorbidities affecting COVID-19 patients. Peripheral blood samples were collected from 35 COVID-19 patients, 16 recovered individuals, and 25 healthy controls, and analyzed using flow cytometry.

The Use of a Unilateral Curved Spreader Graft in the Management of Crooked Nose Deformity.

Aim Of Work: The aim of this study is to present a new technique of using spreader grafts in the correction of crooked nose deformity with C-shaped deviation of the middle third of the nose.

Patients And Methods: This is a prospective case series study conducted on 18 patients with crooked nose deformity with C-shaped deviation of the middle third of the nose. All of the patients were managed by open septorhinoplasty.

Hepatitis B Immunization Status in Children with Chronic Kidney Disease: Experience at a Single Center, Egypt.

Children with chronic kidney disease (CKD), particularly those who require hemodialysis (HD), are at high risk of hepatitis B virus (HBV) infection. The HBV vaccine non-/hypo-response rate among HD children remains high, and it is critical to investigate the influencing factors and their linkages. The aim of this study was to identify the pattern of HB vaccination response in HD children and to analyze the interference of various clinical and biomedical factors with the immunological response to HB vaccination.

Galectin-3 as an early marker of diastolic dysfunction in children with end-stage renal disease on regular hemodialysis.

Introduction And Aim: Diastolic dysfunction is a common finding in end-stage renal disease (ESRD) on regular hemodialysis (HD). Galectin-3 (Gal-3) has emerged as an early biomarker with diagnostic and prognostic values in cardiac dysfunction with reduced or preserved ejection fraction. We aimed to assess the correlation between Gal-3 levels and diastolic dysfunction in children with ESRD on regular HD.
