Critical patients require mechanical ventilation and intensive care unit (ICU) admission, whereas non-critical patients require neither mechanical ventilation nor ICU admission. Several factors have been recently identified as effective factors, including blood cell count, enzymes, blood markers, and underlying diseases.

Our research involves a comprehensive analysis of 100 burn patients, encompassing crucial clinical parameters such as the burn severity index, serum albumin, vitamin D, and calcium levels at admission. Data were meticulously entered into IBM Statistics SPSS software version 28 and subjected to statistical analysis.

Introduction: According to the ALP poisoning that commonly results in death, we aimed to evaluate the prevalence of ALP pill poisoning by employing register-based research.
Methods: In this descriptive cross-sectional study, all selected patients diagnosed and confirmed with ALP poisoning by a specialist and referred to the poisoning ward from the beginning of April 2016 to the end of October 2017 were enrolled, and data were registered in the Disease Registration System by a technical expert for daily follow-up during hospitalization.
Purpose: Tumor necrosis factor alpha (TNF-α) is an inflammatory cytokine which may play a role in the development of gastric cancer (GC). This study aimed to investigate the association of five TNF-α polymorphisms including TNF-α-857, TNF-α-1031, TNF-α-863, TNF-α-308, and TNF-α-238 polymorphisms with GC risk.
Methods: All eligible case-control studies were collected by searching PubMed, Scopus, and Web of Science.
Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of the global outbreak of coronavirus disease 2019 (Covid-19), which has been considered as a pandemic by WHO. SARS-CoV-2 encodes four major structural proteins, among which spike protein has always been a main target for new vaccine studies. This in silico study aimed to investigate some physicochemical, functional, immunological, and structural features of spike protein using several bioinformatics tools.

Results: This cross-sectional study conducted over a two-year period during 2018-2020 on all cases of SSIs who had a positive culture for a GNB. Standard microbiological tests were followed for the bacterial isolation and identification.
Purpose: The pathogenesis of Pseudomonas aeruginosa is multifactorial and attributed to the production of several cell-associated and extracellular virulence factors including those implicated in adherence, iron uptake, exoenzymes (Exo) and exotoxins. The present study aimed to determine the prevalence of type III secretion systems (T3SS) effectors in Iranian burn patients with P. aeruginosa wound infection.

The emergence of ST131 has become a public health threat because this clonal group typically exhibits multiple virulence factors and antimicrobial resistance. Therefore, this study aimed to analyze the literature published on the estimation of the prevalence of clone ST131 among strains isolated from patients with urinary tract infections in western Asia.

The aim of this study was to investigate the toxin profiles and antimicrobial resistance patterns of isolates obtained from hospitalized patients in Shiraz, Iran.
Materials And Methods: This study was performed on 45 toxigenic isolates.
The present systematic review and meta-analysis study aimed to investigate the prevalence of class 1 integrons and their associated antibiotic resistance in uropathogenic A systematic search was conducted to identify studies meeting our inclusion criteria in the Web of Science, PubMed, Embase, Scopus, and Google Scholar electronic databases to the end of July 2019. Finally, 35 articles were selected for data extraction, and meta-analysis was performed using the metaprop program in the STATA, version 11.0, software.
