Sepsis, or systemic inflammatory response to infection, is a major childhood disease and a common cause of death in children. Despite its importance, a global perspective on the epidemiology and mortality of pediatric sepsis across the world is still lacking. ⋯ Educational efforts aiming to increase the awareness on sepsis by the general public and the adherence to the treatment guidelines by healthcare providers may result in significant improvements in sepsis survival. The global attention to pediatric sepsis, however, can only be achieved with the standardization of the definitions and the use of simple and sensitive diagnostic criteria that incorporate the differences in the necessities among different settings and the availability of local resources.

Fluid resuscitation plays a fundamental role in the treatment of septic shock. Administration of inappropriately large quantities of fluid may lead to volume overload, which is increasingly recognized as an independent risk factor for morbidity and mortality in critical illness. ⋯ In fact, achievement of a negative fluid balance during treatment of sepsis is associated with better outcomes. This review will discuss the relationship between fluid overload and unfavorable outcomes in sepsis, and how fluid overload can be prevented and managed.

Prevention or Treatment of Ards With Aspirin: A Review of Preclinical Models and Meta-Analysis of Clinical Studies.
The acute respiratory distress syndrome (ARDS) is a life-threating disorder that contributes significantly to critical illness. No specific pharmacological interventions directed at lung injury itself have proven effective in improving outcome of patients with ARDS. Platelet activation was identified as a key component in ARDS pathophysiology and may provide an opportunity for preventive and therapeutic strategies. We hypothesize that use of acetyl salicylic acid (ASA) may prevent and/or attenuate lung injury. ⋯ This systematic review of preclinical studies and meta-analysis of clinical studies suggests a beneficial role for ASA in ARDS prevention and treatment. However, the currently available data is insufficient to justify an indication for ASA in ARDS. The body of literature does support further studies in humans. We suggest clinical trials in which the mechanisms of action of ASA in lung injury models are being evaluated to guide optimal timing and dose, before prospective randomized trials.

Sepsis is a systemic inflammatory response caused by infection whose molecular mechanisms are still not completely understood. The early detection of sepsis remains a great challenge for clinicians because no single biomarker capable of its reliable prediction, hence, delayed diagnosis frequently undermines treatment efforts, thereby contributing to high mortality. There are several experimental approaches used to reveal the molecular mechanism of sepsis progression. ⋯ Recent advancement in liquid chromatography-based separation methods and mass spectrometers resolution and sensitivity with absolute quantitation methods, made possible to use proteomics as a powerful tool for study of clinical samples with higher coverage proteome profiles. In recent years, number of proteomic studies have been done under sepsis and/or in response to endotoxin and showed various signaling pathways, functions, and biomarkers. This review enlightened the proteomic progress in the last decade in sepsis.

Since the first edition of Surviving Sepsis Campaign Guidelines, the administration of intravenous antibiotics in the first hours of sepsis is recommend. However, in the last ten years, several studies around importance of early antibiotics in emergency room or in intensive care unit produced disparate results. Therefore, is early administration of antibiotics a life-salver? In this article, we explore studies around this theme and some questions about what does "early antibiotics" mean are addressed.
