The objectives of this review are to describe the limitations of commonly used clinical outcomes [e.g., mortality, ventilation parameters, need for extracorporeal membrane oxygenation (ECMO), pediatric intensive care unit (PICU) and hospital length of stay (LOS)] in pediatric acute respiratory distress syndrome (PARDS) studies; and to explore other pertinent clinical outcomes that pediatric critical care practitioners should consider in future clinical practice and research studies. These include long-term pulmonary function, risk of pulmonary hypertension (PHT), nutrition status and growth, PICU-acquired weakness, neurological outcomes and neurocognitive development, functional status, health-related quality of life (HRQOL)], health-care costs, caregiver and family stress. PubMed was searched using the following keywords or medical subject headings (MESH): "acute lung injury (ALI)", "acute respiratory distress syndrome (ARDS)", "pediatric acute respiratory distress syndrome (PARDS)", "acute hypoxemia respiratory failure", "outcomes", "pediatric intensive care unit (PICU)", "lung function", "pulmonary hypertension", "growth", "nutrition', "steroid", "PICU-acquired weakness", "functional status scale", "neurocognitive", "psychology", "health-care expenditure", and "HRQOL". ⋯ As such, available studies were not able to provide conclusive answers to most of our clinical queries. There remains a paucity of data on contemporary clinical outcomes in PARDS studies. In addition to the current commonly used outcomes, clinical researchers and investigators should consider examining these contemporary outcome measures in PARDS studies in the future.

The pediatric acute respiratory distress syndrome (PARDS), a description specific for children with acute respiratory distress syndrome (ARDS), was proposed in the recent Pediatric Acute Lung Injury Consensus Conference (PALICC, 2015). This recent standardization of PARDS diagnosis is expected to aid in uniform earlier recognition of the entity, enable use of consistent management strategies and potentially increase the ease of enrollment in future PARDS clinical trials-all of which are expected to optimize outcomes in PARDS. Clinical trials in PARDS are few but ongoing studies are expected to lay the foundation for future clinical studies. ⋯ Information from these studies could be used to design future clinical trials in PARDS and to lessen the anecdotal or extrapolated experiences from adult clinical studies that often guide clinical practices in PARDS management. Finally, it is expected that these definitions and management strategies will be revised periodically as our understanding of PARDS evolves. Emerging data on PARDS subtypes suggest that patient heterogeneity is an important factor in designing these clinical trials.

Acute respiratory distress syndrome (ARDS) has been known to occur in children since early descriptions of the disease, but pediatric specific diagnostic criteria were first established in 2015 with the Pediatric Acute Lung Injury Consensus Conference (PALICC) definition of pediatric ARDS (PARDS). There were substantial changes proposed with the PALICC definition, including simplification of radiographic criteria, use of pulse oximetry based metrics to define PARDS, specific criteria for non-invasive ventilation, and the use of oxygenation index (OI) instead of PaO2/FiO2 ratio for those on invasive ventilation. ⋯ This highlights that the PARDS definition is likely catching up to changes in clinical practice, and suggests that this new definition should be used moving forward as it is more reflective of current practice than historical definitions. However, it is also clear that PARDS severity alone (as measured by the PALICC) criteria insufficiently characterizes the risk for mortality or other important clinical outcomes amongst PARDS patients, although there appears to be some association between PARDS severity and outcome, particularly when hypoxemia is severe.

Septic shock is one of the major healthcare problems, affecting millions of people around the world every year. The object of this study is to find the best kind of regimen of vasopressors treatment in septic shock. ⋯ Single dopamine had significantly higher 28d mortality. Combination regimens of vasopressors accounted for the best three therapeutic regimens. In treating patients with septic shock, using combining regimens probably gets more benefits.

Several studies have investigated the diagnostic accuracy of serum lactate dehydrogenase (LDH) to pleural fluid adenosine deaminase ratio (cancer ratio, CR) for malignant pleural effusion (MPE), but the results were various. Therefore, we performed this systematic review and meta-analysis to ascertain the diagnostic accuracy of CR for MPE. ⋯ CR has high diagnostic accuracy for MPE. Considering the design weaknesses of available studies, further studies with rigorous design are needed to further validate the findings of this meta-analysis.
