Coronavirus disease 2019 (COVID-19) has spread rapidly worldwide, leading to a pandemic. In China, Xiyanping injection (XYP) has been recommended as a drug for COVID-19 treatment in the Guideline on Diagnosis and Treatment of COVID-19 by the National Health Commission of the People Republic of China and National Administration of Traditional Chinese Medicine (Trial eighth Edition). However, the relevant mechanisms at the molecular-level need to be further elucidated. ⋯ Through effective network pharmacology analysis and molecular docking, this study suggests that XYP contains many effective compounds that may target COVID-19 related signaling pathways. Moreover, the in vitro experiment confirmed that XYP could inhibit the cytokine storm by regulating genes or proteins related to immune and inflammatory responses.

Acute pulmonary embolism (PE) is a life-threatening condition in patients with Coronavirus disease-2019 (COVID-19). Computed tomography pulmonary angiography is the preferred test to confirm the diagnosis. However, computed tomography pulmonary angiography is expensive and is not available in every clinic. ⋯ A decrease in eosinophil levels, whereas an increase in CLR, D-dimer, and CRP may predict PE. Elevated CLR is highly predictive of PE and is associated with increased mortality risk. COVID-19 patients with a CLR level above 81 should be investigated for PE.

Coronavirus disease 2019 (COVID-19) has ravaged the world since December 2019. Up to now, it is still prevalent around the world. Vaccines are an important means to prevent the spread of COVID-19 and reduce severe disease and mortality. ⋯ Among them, the advantages of COVID-19 messenger ribonucleic acid (mRNA) vaccine, such as better adaptability to variant strains and better immune response ability, have attracted great attention. However, different populations with different genders, ages, previous COVID-19 infection history, underlying diseases and treatments will show different antibody responses after mRNA vaccination, which will affect the protection of the vaccine. Based on this, this paper reviews the reports related severe acute respiratory syndrome Coronavirus 2 mRNA vaccines, and summarizes the effectiveness of vaccines in different populations and different disease states and looked forward to the precise vaccination strategy of the vaccine in the future.

Sickle cell disease (SCD) has been found to be associated with an increased risk of hospitalization and death from coronavirus disease-2019 (COVID-19). We sought to study clinical outcomes in patients with SCD and a diagnosis of COVID-19 infection. ⋯ We identified a lower mortality (3.9%) rate among patients in our cohort in comparison to previous studies and a higher burden of inpatient hospitalizations as compared to outpatient/ER management. Further prospective data are needed to validate these findings. Key messages What is already known on this topic COVID-19 has been shown to have a disproportionately unfavorable impact on African Americans, including longer hospital stays, higher rates of ventilator dependence, and a higher overall mortality rate. Limited data also suggest that sickle cell disease (SCD) is associated with an increased risk of hospitalization and death from COVID-19. What this study adds Our analysis did not show a higher mortality due to COVID-19 in patients with SCD. However, we identified a high burden of inpatient hospitalizations in this population. COVID-19-related outcomes did not improve with the use of disease-modifying therapies. How this study might affect research, practice, or policy These results will aid in decision making for triage of patients with COVID-19 and SCD and ensure the most appropriate use of healthcare resources. Our analysis underscores the need for more robust data to identify patients at higher risk of severe disease and/or mortality, necessitating inpatient hospitalization and aggressive management.
