Short-term effects of air pollution on hospital admissions of respiratory diseases in Hamadan, Iran, 2015 to 2021
This study aims to investigate the effect of short-term exposure to air pollutants on respiratory hospital admissions in the city of Hamadan. In this ecological study, daily hospital admission data were collected from Shahid Beheshti Hospital in Hamadan. Daily information on air pollutants (CO, SO2, NO2, O3, PM2.5 and PM10) from Hamadan Department of Environment (DoE) organization and of climate factors from Hamadan Meteorological Office were collected. A negative binomial regression model was used to examine the effect of air pollution on daily respiratory hospitalizations. The effect of exposure to pollutants was measure...

Prevalence of Clostridium perfringens toxinotypes in antibiotic-associated diarrhoeal (AAD) patients in Iranian hospitals; can toxinotype D serve as a possible zoonotic agent for humans?
This study persists in considering toxinotype F in Iranian AAD patients as it was the dominant C. perfringens toxinotype. Remarkably, the isolation of toxinotype D suggests it as a potential trigger in C. perfringens-associated AAD for the first time and highlights it as a possible zoonotic agent for humans.PMID:37597720 | DOI:10.1016/j.actatropica.2023.107002

Relationship between antibiotic resistance with class 1 integron and SmeDEF efflux pump encoding genes in clinical isolates of Stenotrophomonas maltophilia
J Appl Genet. 2023 Aug 14. doi: 10.1007/s13353-023-00776-6. Online ahead of print.ABSTRACTStenotrophomonas maltophilia is an emerging multidrug-resistant organism with an increasing frequency of hospital-acquired infections predominantly in developing countries. The purpose of this study was to determine the antibiotic resistance and frequency of the smeD, class 1 integron, and sul1 genes in clinical isolates of S. maltophilia in two Iranian provinces. From January 2020 to September 2021, 38 clinical isolates of S. maltophilia were collected from patients in hospitals in Tabriz and Sanandaj provinces of Iran. S. maltophili...

Clinical Characteristics and Economic Burden of Asthma in China: A Multicenter Retrospective Study
Iran J Allergy Asthma Immunol. 2023 Jun 16;22(3):290-298. doi: 10.18502/ijaai.v22i3.13057.ABSTRACTAsthma is a common chronic airway inflammation that produces a healthcare burden on the economy. We aim to obtain a better understanding of the clinical status and disease burden of patients with asthma in China. A retrospective study was carried out based on the computerized medical records in the Jinan Health Medical Big Data Platform between 2011 and 2019 (available data from 38 hospitals). The asthma severity of each patient was assessed retrospectively and categorized as mild, moderate, or severe according to Global Initi...
