The durability of infection-induced severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunity has crucial implications for reinfection and vaccine effectiveness. However, the relationship between disease 2019 (COVID-19) severity long-term anti-SARS-CoV-2 immunoglobulin G (IgG) antibody level is poorly understood. Here, we measured longevity SARS-CoV-2-specific IgG antibodies in survivors who had recovered from COVID-19 1 year previously. In a cohort 473 with varying...

Abstract Background The serum surfactant protein D (SP-D) level is suggested to be a useful biomarker for acute lung injuries and respiratory distress syndrome. Whether the SP-D could identify severity of coronavirus disease 2019 (COVID-19) in early stage has not been elucidated. Methods We performed an observational study on 39 laboratory-confirmed COVID-19 patients from Fourth People’s Hospital Yiyang, Hunan, China. Receiver operating characteristic (ROC) curve analysis, correlation...

COVID-19 is characterized by endothelial dysfunction and presumed to have long-term cardiovascular sequelae. In this cross-sectional study, we aimed explore the serum levels of biomarkers in patients who recovered from one year after hospital discharge.In clinical follow-up 345 survivors Huanggang, Hubei, 119 age gender-matched medical staff as healthy controls were enrolled. A standardized symptom questionnaire was performed, while electrocardiogram Doppler ultrasound lower extremities,...

Cardiac arrest (CA) is a serious cardiac event, which has high incidence and low survival rate at home abroad. In order to predict the risk of CA in advance, large number studies have been conducted by relevant researchers. This paper mainly summarizes characteristics research status existing analysis prediction from three aspects: factors CA, evaluation index early warning scoring system CA. We hope it can help medical staff understand current progress this field, provide new ways methods...
