Review Meta Analysis
Risk of type III secretion systems in burn patients with Pseudomonas aeruginosa wound infection: A systematic review and meta-analysis.
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. ⋯ Our results showed a remarkable prevalence of T3SS-positive genotype in patients with burn injuries. These findings provided attractive targets for new therapeutic strategies for burn patients who were infected with cytotoxin-producing P. aeruginosa.

Extensive burns is one of the most common severe injuries, with a high annual death rate. Previous studies showed that the neutrophil to lymphocyte ratio (NLR) is a prognostic factor for some inflammatory diseases. However, until now, no study has evaluated the clinical prognostic value of NLR in extensively burned patients. The aim of this study was to investigate the prognostic value of NLR in this medical condition to provide clinical guidance. ⋯ NLR continuously decreased in the first 3 days of hospitalization. Admission NLR above 14 is associated with a decreased survival in patients with extensive burns. These findings demonstrate that NLR has prognostic value in these patients.
