(2020-04-10)In the fight against coronavirus disease 2019 (COVID-19), now a worldwide pandemic, urgent identification of clinical and laboratory predictors of progression towards severe and fatal forms is urgently needed. These ... -
Hematological findings and complications of COVID‐19
(2020-04-13)COVID‐19 is a systemic infection with a significant impact on the hematopoietic system and hemostasis. Lymphopenia may be considered as a cardinal laboratory finding, with prognostic potential. Neutrophil/lymphocyte ratio ... -
Heparin therapy improving hypoxia in COVID-19 patients - a case series
(2020-04-30)INTRODUCTION: Elevated D-dimer is a predictor of severity and mortality in COVID-19 patients and heparin use during in-hospital stay has been associated with decreased mortality. COVID-19 patient autopsies have revealed ... -
Heparin-induced thrombocytopenia is associated with a high risk of mortality in critical COVID-19 patients receiving heparin-involved treatment
(2020-04-28)Background Coronavirus infectious disease 2019 (COVID-19) has developed into a global pandemic. It is essential to investigate the clinical characteristics of COVID-19 and uncover potential risk factors for severe disease ... -
High frequency of SARS-CoV-2 RNAemia and association with severe disease
(2020-05-01)Background: Detection of SARS-CoV-2 RNA in the blood, also known as RNAemia, has been reported, but its prognostic implications are not well understood. This study aimed to determine the frequency of SARS-CoV-2 RNA in ... -
High levels of PEEP are not better than low levels for reducing mortality in adult ICU patients with acute respiratory distress syndrome (ARDS) or acute lung injury (ALI)
(2020-03-18)What is this? Some patients with COVID-19 will develop acute respiratory distress syndrome (ARDS) or acute lung injury (ALI) and need help with their breathing. This might be provided by mechanical ventilation (MV) in an ... -
High rate of increased level of plasma Angiotensin II and its gender difference in COVID-19: an analysis of 55 hospitalized patients with COVID-19 in a single hospital, WuHan, China
(2020-05-01)Background: 2019 Novel coronavirus disease (COVID−19) is turning into a pandemic globally lately. Angiotensin-converting enzyme 2 (ACE2) is identified as an important functional receptor for SARS−Cov−2. ACE2 and ACE are ... -
High seroreactivity against SARS-CoV-2 Spike epitopes in a pre SARS-CoV-2 cohort: implications for antibody testing and vaccine design
(2020-05-22)Little is known about the quality of polyclonal antibody responses in COVID-19 patients, and how it correlates with disease severity or patients' prior exposure to other pathogens. The whole polyclonal antibody repertoire ... -
High specificity of a novel Zika virus ELISA in European patients after exposure to different flaviviruses
(2016-06)The current Zika virus (ZIKV) epidemic in the Americas caused an increase in diagnostic requests in European countries. Here we demonstrate high specificity of the Euroimmun anti-ZIKV IgG and IgM ELISA tests using putative ... -
High-flow nasal cannula for acute hypoxemic respiratory failure in patients with COVID-19: systematic reviews of effectiveness and its risks of aerosolization, dispersion, and infection transmission
(2020-06-15)Purpose: We conducted two World Health Organization-commissioned reviews to inform use of high-flow nasal cannula (HFNC) in patients with coronavirus disease (COVID-19). We synthesized the evidence regarding efficacy and ... -
