Meta Analysis
Dexamethasone for the treatment of acute respiratory distress syndrome: A systematic review and meta-analysis.
This meta-analysis aimed to evaluate the efficacy and safety of dexamethasone in the treatment of acute respiratory distress syndrome (ARDS). ⋯ Evidence from the meta-analysis suggests that dexamethasone is an effective and relatively safe treatment for all-cause mortality and ventilator-free status at 28 days in patients with ARDS. Owning to the small number of eligible RCTs, the conclusions of present study are warranted in the future study.

Randomized Controlled Trial
The prognostic value of early measures of the ventilatory ratio in the ARDS ROSE trial.
The ventilatory ratio (VR, [minute ventilation × PaCO2]/[predicted body weight × 100 × 37.5]) is associated with mortality in ARDS. The aims of this study were to test whether baseline disease severity or neuromuscular blockade (NMB) modified the relationship between VR and mortality. ⋯ Elevated baseline and day 1 VR were associated with higher 28-day mortality. The relationship between baseline VR and mortality was stronger among patients with lower APACHE-III. APACHE-III was not an effect modifier for the relationship between VR trajectory and mortality, so that the VR trajectory may be optimally suited for prognostication and predictive enrichment. VR was not different between patients randomized to NMB or control, indicating that VR can be utilized without correcting for NMB.

Patients with severe acute respiratory distress syndrome (ARDS) have high mortality rates; therefore, new biomarkers are necessary to predict the prognosis in the early stages. Serum lactate dehydrogenase (LDH) level is a specific marker of lung damage, but it is not sensitive because it is affected by several factors. This study aimed to determine whether the LDH/albumin ratio could be used as a prognostic biomarker in patients with severe ARDS due to COVID 19. ⋯ LDH/albumin ratio can be used as an independent prognostic factor for mortality in patients with severe ARDS caused by COVID-19.

Hypoalbuminemia is associated with fluid overload, the development of acute respiratory distress syndrome, and mortality. The co-administration of albumin and diuretics for the treatment of patients with hypoalbuminemia is expected to increase urine output, without hemodynamic instability, and improve pulmonary function; however, these effects have not been systematically investigated. Here, we aimed to clarify the benefits of the co-administration of albumin and diuretics in mechanically ventilated patients. ⋯ Although this treatment combination reduced the number of days for which mechanical ventilation was required, it did not reduce the all-cause mortality at 30 days. In conclusion, the co-administration of albumin and diuretics may reduce hypotensive events and improve the P/F ratio at 24 hours.
