Assessment of meteorological factors and air pollution impact on cardiovascular mortality using random forest analysis 2017 to 2020.

Air pollution, a global health hazard, significantly impacts mortality, cardiovascular health, mental well-being, and overall human health. This study aimed to investigate the impact of air pollution and meteorological factors on cardiovascular mortality rates in Mashhad City, northeastern Iran in 2017-2020. We utilized a Random Forest (RF) model in this study.

Molecular typing and virulence characteristics of Escherichia coli strains isolated from hospital and community acquired urinary tract infections.

Background: The main causes of hospital- and community-acquired urinary tract infections (UTIs) are a group of Escherichia coli (E. coli) strains with multiple virulence factors known as uropathogenic E. coli.

Extraction and characterization of cellulose microfibers from cornhusk for application as reinforcing agent in biocomposite.

This study aims to extract and characterize cellulose microfibers from cornhusk, an agricultural by-product. The extracted fibers will then be used as a reinforcing agent in a biocomposite made of thermoplastic corn starch. The process of extracting cellulose microfibers involved two treatments: sequential alkali treatment (using sodium hydroxide at 120 °C for 120 min) and peroxide bleach treatment (using hydrogen peroxide at 90 °C for 60 min).

Evaluating clinical communication skills of medical students, assistants, and professors.

Background: The skill of communicating with the patient is one of the basic clinical skills and part of the necessary competencies for medical doctors. The present study aimed to evaluate the knowledge, attitude, and performance (KAP) of medical students, assistants, and professors of Shahrekord University of Medical Sciences regarding clinical communication skills with patients.

Method: This cross-sectional study was conducted at the hospitals of Shahrekord University of Medical Sciences in Iran.

Relationship Between BMI and Disease Severity in COVID-19 Patients.

Background: Obesity and increased body mass index (BMI) are associated with coronavirus disease 2019 (COVID-19)-related complications and severity. They can exacerbate the cytokine storm and lead to severe symptoms or death in obese patients.

Objectives: This cross-sectional descriptive study included patients with COVID-19 admitted to the Razi Hospital in Ahvaz, Iran, from January 2019 to December 2020.
