There are concerns that angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) may worsen the outcomes of patients with COVID-19. This systematic review and meta-analysis aimed to study the in-hospital mortality among COVID-19 patients who were on ACEIs/ARBs as compared to those not on ACEIs/ARBs. ⋯ We observed that ACEIs/ARBs had no significant impact on the in-hospital mortality of COVID-19 patients and can be used safely in patients with indications.

Noninvasive ventilation (NIV) with continuous positive airway pressure (CPAP) has been shown to decrease endotracheal intubation and mortality in patients with acute cardiogenic pulmonary oedema (ACPE). The Three Interventions in Cardiogenic Pulmonary Oedema showed no advantage of NIV over standard medical therapy. This meta-analysis is an update on the efficacy and safety of two different forms of NIV (noninvasive pressure support ventilation [NIPSV] vs. CPAP) in patients with ACPE. ⋯ NIPSV appears to be as safe and efficacious as CPAP, if titrated rather than fixed pressures are employed.

Immunosuppressive therapy has been shown to improve outcomes in patients with paraquat poisoning. The objective of this study was to evaluate the efficacy of immunosuppressive therapy in the management of lung injury due to paraquat poisoning. ⋯ One out of four patients (95 percent CI 3-5) were successfully treated with immunosuppressive therapy for paraquat poisoning. However, due to significant heterogeneity and publication bias, a large randomised controlled trial will be required to affirm the role of immunosuppression in paraquat poisoning.
