A Proactive Approach for Managing COVID-19: The Importance of Understanding the Motivational Roots of Vaccination Hesitancy for SARS-CoV2.
Vaccination hesitancy-the reluctance or refusal to be vaccinated-is a leading global health threat (World Health Organization, 2019). It is imperative to identify the prevalence of vaccination hesitancy for SARS-CoV2 in order to understand the scope of the problem and to identify its motivational roots in order to proactively prepare to address the problem when a vaccine eventually becomes available. ⋯ Vaccination hesitancy is a major looming problem for COVID-19. To improve vaccine uptake, it is imperative that the vaccine is demonstrated to the public to be rigorously tested and not perceived as rushed or premature in its dissemination.

This study aimed to develop a deep-learning model and a risk-score system using clinical variables to predict intensive care unit (ICU) admission and in-hospital mortality in COVID-19 patients. ⋯ Deep learning and the resultant risk score have the potential to provide frontline physicians with quantitative tools to stratify patients more effectively in time-sensitive and resource-constrained circumstances.

COVID-19 is currently causing concern in the medical community as the virus is spreading around the world. It has a heavy global burden, particularly in low-income countries. The clinical spectrum of COVID-19 pneumonia ranges from mild to critically ill cases and Acute Respiratory Distress Syndrome. ⋯ In total, mortality in the ICU was 25% (n = 18) among ARDS patients over two weeks. COVID-19 induced ARDS is a major concern. The rapid progression of ARDS needs specific protocol based on patients' characteristics and rapid action.

The paper describes 4 autopsy cases of myocarditis in elderly patients with confirmed coronavirus infection. It gives the data of a morphological study of heart specimens and a detailed characterization of a myocardial infiltrate. ⋯ The fact that lymphocytic viral myocarditis can develop in COVID-19 was morphologically and immunohistochemically confirmed. The features of myocarditis in COVID-19 are the development of the former in the presence of coronaritis and the possibility of its concurrence with lymphocytic endo- and pericarditis.

Case ReportsDetection of SARS-CoV-2 by bronchoscopy after negative nasopharyngeal testing: Stay vigilant for COVID-19.
Real-time polymerase chain reaction (RT-PCR) detection of severe acute respiratory syndrome coronavirus (SARS-CoV-2) is required for diagnosis of coronavirus disease 2019 (COVID-19). Sensitivity of RT-PCR nasopharyngeal (NP) testing is presumed to be high, but there is no gold standard against which this has been determined. The objective was to determine whether lower respiratory tract infection (LRTI), detected in bronchoalveolar lavage fluid (BALF), occurs in the absence of upper respiratory tract infection with clinical testing of both specimen types. ⋯ These data demonstrate that SARS-CoV-2 LRTI occurs in the presence of negative NP testing. NP testing may underestimate the prevalence of COVID-19 and has implications for spread of SARS-CoV2 in the community and healthcare setting.
