ReviewThe Role of Endotheliitis in COVID-19: Real-world Experience of 11,190 Patients and Literature Review for a Pathophysiological Map to Clinical Categorization.
COVID-19 may yield a variety of clinical pictures, differing from pneumonitis to Acute Respiratory Distress Syndrome along with vascular damage in the lung tissue, named endotheliitis. To date, no specific treatment strategy was approved for the prevention or treatment of COVID-19 in terms of endotheliitis-related comorbidities. Here, we presented our treatment strategies for 11 190 COVID-19 patients depending on categorisation by the severity of both the respiratory and vascular distress and presented the manifestations of endotheliitis in skin, lung and brain tissues according to the different phases of COVID-19. ⋯ Distinctive manifestations in each COVID-19 patient, including non-respiratory conditions in the acute phase and the emerging risk of long-lasting complications, suggest that COVID-19 has endotheliitis-centred thrombo-inflammatory pathophysiology. Daily evaluation of clinical, laboratory and radiological findings of patients and deciding appropriate pathophysiological treatment would help to reduce the mortality rate of COVID-19.

The novel coronavirus-associated ARDS (COVID-19 ARDS) often requires invasive mechanical ventilation. A spectrum of atypical ARDS with different phenotypes (high vs low static compliance) has been hypothesized in COVID-19. ⋯ In our cohort of mechanically ventilated COVID-19 ARDS subjects, high PEEP and D-dimer were associated with increase in physiologic dead space without significant effect on oxygenation, raising the question of potential microvascular dysfunction.

Achieving Safe Liberation During Weaning from VV-ECMO in Patients with Severe ARDS: The role of Tidal Volume and Inspiratory Effort.
Weaning from venovenous extracorporeal membrane oxygenation (VV-ECMO) has not been not well studied. VV-ECMO can be discontinued when patients tolerate noninjurious mechanical ventilation (MV) during a sweep gas-off trial (SGOT). However, predictors of safe liberation are unknown. ⋯ Patients with higher tidal volume, heart rate, ventilatory ratio, and esophageal pressures swings during SGOT were less likely to achieve safe liberation from VV-ECMO.

Results of recent studies suggest that the incidence and mortality of ARDS may be higher than previously thought in pediatric trauma patients. We conducted a systematic review of the literature on incidence, risk factors, prognostic factors, and outcomes of ARDS after pediatric trauma in the ICU. ⋯ The ARDS incidence of 4.2% in the subjects with pediatric trauma in the ICU was comparable with 3.2% in the general pediatric ICU population; however, mortality associated with trauma-associated ARDS was higher and more commonly due to multi-system organ failure rather than hypoxemia.
