Asthma is a chronic inflammatory disorder of the airways characterized by recurrent episodes of wheezing, breathlessness, chest tightness, and coughing. The pathophysiology involves various cells and cellular components, including mast cells, eosinophils, T lymphocytes, macrophages, neutrophils, and epithelial cells. This inflammation leads to widespread but variable airflow obstruction and increased bronchial sensitivity to a range of stimuli. Asthma affects over 330 million people worldwide, with prevalence rates varying widely between countries. Epidemiological studies have shown increasing

Electronic health records (EHRs) have become increasingly prevalent in healthcare settings, particularly in Saudi Arabia. This study aimed to assess nurses' competency and attitudes toward using EHRs in various Saudi hospitals. A descriptive, cross-sectional study was conducted using a questionnaire distributed to a random sample of 724 nurses. The questionnaire explored three key dimensions: EHRs and patient care coordination, usability and effectiveness of EHRs, and workload implications. Results showed that nurses generally held positive views on EHRs, with 80.11% agreeing that EHRs improve

Medication errors are a significant cause of morbidity and mortality globally, particularly in hospital settings. This comprehensive review explores the types, causes, and strategies for preventing medication errors in pediatric and adult populations, with a focus on the critical role of pharmacists. Medication errors can occur at any stage of the therapeutic management process, including prescribing, transcribing, dispensing, preparing and administering, and monitoring medications and patients. Prescribing errors, such as incorrect dosage or route, are particularly concerning in pediatric set

In this study, we have conducted an inquiry into the segregation of wavelengths of Gaussian light beams with the aid of corrugated triangular wave-index interfaces using the beam propagation method (BPM). We present a newfangled approach for optical wavelength demultiplexing (DEMUX) which depends on two phenomena: the Goos-Haenchen (GH) shift and continuous refraction at a corrugated triangular wave-index medium interface. The reflected beams undergo varying lateral shifts (GH shifts), contingent on the wavelength, thus accomplishing the requisite spatial beam separation. The two light beams p

Energy conservation in water treatment plants is a vital topic, as these facilities are essential worldwide and are among the largest consumers of electricity. Improving energy efficiency in these facilities can significantly reduce operational costs and minimize environmental impact. Our research highlights a critical issue in energy consumption at water purification plants in Egypt. The implementation of variable speed drives (inverters) to control the speed of the filtered water pumps represents a significant advancement over traditional control methods. By allowing for real-time adjustment
