Assessment of diagnostic and prognostic laboratory biomarkers in severe COVID-19 patients admitted to intensive care unit.

Coronavirus disease (COVID-19) is a global pandemic. In the first two years of the pandemic, nearly 15 million people died worldwide. Accurate and rapid laboratory diagnosis of COVID-19 infection is one of the milestones of pandemic control.

Neutrophil to lymphocytic ratio and other inflammatory markers as adverse outcome predictor in hospitalized COVID-19 patients.

Early risk classification of coronavirus disease 2019 (COVID-19) patients admitted to hospital is a critical key for providing optimal interventions. We investigated whether neutrophil-to-lymphocyte ratio (NLR) levels and other inflammatory and coagulation markers could be predictors for the severity and mortality of hospitalized COVID-19 patients. This cross-sectional study included 155 COVID-19 patients diagnosed by the reverse transcription polymerase chain reaction (RT-PCR) using oropharyngeal swabs.

Effect of smoking on the macula and optic nerve integrity using optical coherence tomography angiography.

Objective: To investigate the effect of chronic smoking on the macula and optic nerve integrity using optical coherence tomography angiography (OCTA).

Methods: This prospective, comparative study involved the right eyes of 160 healthy subjects (80 smokers group, and 80 control group). OCTA scanning was performed for all subjects.

Serum 25-hydroxyvitamin D and CD4+CD25(+high) FoxP3+ Regulatory T cell as Predictors of Severity of Bronchial Asthma in Children.

Bronchial asthma (BA) is one of the common chronic diseases of childhood. Vitamin D deficiency has been associated with BA. Suppressor regulatory T cells (Treg) are important for the induction, maintenance of immunological tolerance to allergens.

Prevalence of schistosomiasis among patients attending Qena General Hospital over the years 2011 and 2012.

Schistosomiasis is a public health problem in Egypt. To detect the prevalence of schistosomiasis in Qena Governorate, 1601 urine and stool samples of patients attending Qena General Hospital were examined of whom 1601 patients had urinary symptoms and 893 patients had dysentery and bloody stool. Sheets were filled out on each patient.

Skeletal muscle dysfunction in idiopathic pulmonary arterial hypertension.

Despite improvements in survival with disease-targeted therapies, the majority of patients with pulmonary arterial hypertension (PAH) have persistent exercise intolerance that results from impaired cardiac function and skeletal muscle dysfunction. Our intent was to understand the molecular mechanisms mediating skeletal muscle dysfunction in PAH. A total of 12 patients with PAH and 10 matched control subjects were assessed.
