The SARS-CoV-2 pandemic increased the number of patients needing invasive mechanical ventilation, either through an endotracheal tube or through a tracheostomy. Tracheomalacia is a rare but potentially severe complication of mechanical ventilation, which can significantly complicate the weaning process. The aim of this study was to describe the strategies of airway management in mechanically ventilated patients with respiratory failure due to SARS-CoV-2, the incidence of severe tracheomalacia, and investigate the factors associated with its occurrence. ⋯ In our population, approximately 50% of subjects with ARDS due to SARS-CoV-2 were tracheostomized. Tracheostomized subjects had a longer ICU and hospital stay. In our population, 5% were diagnosed with tracheomalacia. This percentage is 10 times higher than what is reported in available literature, and the underlying mechanisms are not fully understood.

The recommendations in several countries to stop using the ChAdOx1 vaccine has led to vaccine programs combining different Coronavirus Disease 2019 (COVID-19) vaccine types, which necessitates knowledge on vaccine effectiveness (VE) of heterologous vaccine schedules. The aim of this Danish nationwide population-based cohort study was therefore to estimate the VE against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection and COVID-19-related hospitalization and death following the first dose of the ChAdOx1 vaccine and the combination of the ChAdOx1/mRNA vaccines. ⋯ In this study, we observed a large reduction in the risk of SARS-CoV-2 infection when combining the ChAdOx1 and an mRNA vaccine, compared with unvaccinated individuals.

There are growing reports of the neurological involvement among patients with coronavirus disease 2019 (COVID-19). Headache, confusion, and anosmia after olfactory nerve disruption are the most prevalent presentation of the neurological involvement related to COVID-19. However, small numbers of the central nervous system involvement have been reported. ⋯ A 49-year-old man was referred to our hospital with abrupt vision loss. Three weeks earlier he was admitted to the hospital based on his respiratory symptoms and was diagnosed with COVID-19 infection. Initial brain magnetic resonance imaging indicated diffuse restricted bilateral foci in both parietal and occipital lobes in favor of acute infarction. Diffuse weighted imaging demonstrated restricted bilateral hyperintense signals in parietal and occipital region. Occipital cortex biopsy showed brain tissue with focal infiltration of foamy macrophages mixed with reactive astrocytes and no plasma cell infiltration. Considering all of the evidence, post-COVID-19 encephalitis diagnosis was considered for the patient, and methyl prednisolone pulse therapy and intravenous immunoglobulin were initiated. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although there are growing reports of neurological involvement among patients, blindness is rarely observed as a complication of post-COVID-19 encephalitis. To our knowledge, this is the first case of post-COVID-19 encephalitis that presented with bilateral vision loss primarily. This case may raise physicians' awareness of neurological complications of COVID-19.

Hyperglycaemia has emerged as an important risk factor for death in coronavirus disease 2019 (COVID-19). The aim of this study was to evaluate the association between blood glucose (BG) levels and in-hospital mortality in non-critically patients hospitalized with COVID-19. ⋯ Admission hyperglycaemia is a strong predictor of all-cause mortality in non-critically hospitalized COVID-19 patients regardless of prior history of diabetes. KEY MESSAGE Admission hyperglycaemia is a stronger and independent risk factor for mortality in COVID-19. Screening for hyperglycaemia, in patients without diabetes, and early treatment of hyperglycaemia should be mandatory in the management of patients hospitalized with COVID-19. Admission hyperglycaemia should not be overlooked in all patients regardless prior history of diabetes.

Observational Study
Combined non-invasive respiratory support therapies to treat SARS-CoV-2 patients: A prospective Observational Study.
The roles of high-flow nasal cannula (HFNC) and CPAP in coronavirus disease 2019 (COVID-19) are controversial. The objective of the study was to evaluate the impact of the application of a noninvasive respiratory support algorithm on clinical outcomes in subjects with COVID-19 and with acute respiratory failure. ⋯ Data from our cohort managed in a respiratory intermediate care unit showed that combined noninvasive respiratory support was feasible, with favorable outcomes. Further prospective studies are required.
