Effect of Air Pollutants Particulate Matter PM, PM, Carbon Monoxide (CO), Nitrogen Dioxide (NO), Sulfur Dioxide (SO), and Ozone (O) on Fractional Exhaled Nitric Oxide (FeNO).

Objectives: This study aimed to investigate the effect of Environmental Pollutants Particulate Matter PM, PM, Carbon Monoxide (CO), Nitrogen Dioxide (NO), Sulfur Dioxide (SO), and Ozone (O) on lung airway inflammation by assessing the Fractional Exhaled Nitric Oxide (FeNO) in students studying in schools located in or away from air-polluted areas.

Methods: This matched case-control cross-sectional study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia from August 2022 to July 2023. In this study, two schools were selected, one was located near a traffic-polluted area (School #1), and the second was located away from the traffic-polluted area (School #2).

Seasonal variations impact on SARS-CoV-2 incidence and mortality in southern and northern hemispheres: Two years pandemic period based study.

Objectives: The Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) infection is a highly challenging problem in the world. The impact of weather conditions on the spread of SARS-CoV-2 has been hypothesized, but the level of understanding remains lacking. This study investigates the impact of seasonal variations on SARS-CoV-2 incidence and mortality in the Southern and Northern hemispheres.
