Meta Analysis
High flow nasal cannula in the immediate post-operative period: a systematic review and meta-analysis.
Studies have demonstrated that high-flow nasal cannula (HFNC) prevents intubation in acute hypoxic respiratory failure when compared with conventional oxygen therapy (COT). However, the data examining routine HFNC use in the immediate postoperative period are less clear. ⋯ With evidence of moderate certainty, prophylactic HFNC reduces reintubation and escalation of respiratory support compared with COT in the immediate postoperative period after cardiothoracic surgery. This effect is likely driven by patients who are at high risk and/or obese. These findings support postoperative prophylactic HFNC use in the patients who are at high risk and/or obese undergoing cardiothoracic surgery.

Meta Analysis
Chest CT imaging signature of COVID-19 infection: in pursuit of the scientific evidence.
Chest CT may be used for the diagnosis of coronavirus disease 2019 (COVID-19), but clear scientific evidence is lacking. Therefore, we systematically reviewed and meta-analyzed the chest CT imaging signature of COVID-19. ⋯ Studies on chest CT imaging findings in COVID-19 suffer from methodologic quality concerns. More high-quality research is necessary to establish diagnostic CT criteria for COVID-19. Based on the available evidence that requires cautious interpretation, several chest CT imaging findings appear to be suggestive of COVID-19, but normal chest CT imaging findings do not exclude COVID-19, not even in symptomatic patients.
