Abnormal healthcare imaging by transportable chest Xray or CT scan of the lungs 4a. Host danger things Neutropenia (absolute neutrophil count 0.five GL) preceding or in the time of ICU admission Underlying hematological or oncological malignancy treated with cytotoxic agents Glucocorticoid therapy (prednisone equivalent 20 mgd and four weeks) Congenital or acquired immunodeficiency 4b.

Categorical variables are reported as numbers and percentages [95 self-confidence interval (95 CI)] and compared as 
suitable. There was no imputation for missing information, except for information missing from comorbidities, which have been then deemed as absent. Aspects linked with ICU mortality had been determined by univariable and multivariable backward logistic regression analyses. Independent variables having a p value 0.ten in univariable evaluation were entered into the multivariable model, with backward elimination of variables displaying a p worth greater than 0.05. Interactions involving variables have been assessed employing the Mantel aenszel test. Analyses have been carried out employing the SPSS Base 21.0 statistical computer software package (SPSS Inc., Chicago, IL).Over the 10-year study period, 423 individuals have been admitted for ARDS, of whom 35 [8.3 , 95 CI (5.40.six)] had a minimum of one particular respiratory tract sample good for Aspergillus spp. (Aspergillus+ individuals) (Fig. 1; Table 1). Amongst 17 (49 ) immunocompromised Aspergillus+ individuals, a single had confirmed IPA, 11 had putative IPA, and five have been categorized as having respiratory tract colonization. Conversely, amongst 18 (51 ) non-immunocompro.
