Health care-associated bloodstream infections represent a major public health concern, significantly impacting morbidity, mortality, and the overall cost of pediatric medical care.
Pulmonary thromboembolism (PTE) is a major cardiovascular emergency associated with significant mortality. Systemic inflammation contributes to the pathogenesis of thrombosis and to disease severity, and hematological indices derived from the complete blood count, such as the neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR), have been proposed as prognostic predictors.
