ABSTRACT

This communication describes a novel water-soluble membrane prepared from chitosan intended for SARS-CoV-2 viral nucleic acid collection and detection. The CSH membrane formed from nanofibers shows promising potential in the quantitative determination of the SARS-CoV-2 viral nucleic acids at a concentration of 102 copies per L in air. The sponge-like structure which allows gas to pass through for collection of viral nucleic acids potentially provides simple, fast, and reliable sampling as well as detection of various types of airborne viruses.

ABSTRACT

ABSTRACT: Mortality of critically ill patients with coronavirus disease 2019 (COVID-19) was high. Aims to examine whether time from symptoms onset to intensive care unit (ICU) admission affects incidence of extra-pulmonary complications and prognosis in order to provide a new insight for reducing the mortality. A single-centered, retrospective, observational study investigated 45 critically ill patients with COVID-19 hospitalized in ICU of The Third People's Hospital of Yichang from January 17 to March 29, 2020. Patients were divided into 2 groups according to time from symptoms onset to ICU admission (>7 and ≤7 days) and into 2 groups according to prognosis (survivors and non-survivors). Epidemiological, clinical, laboratory, radiological characteristics and treatment data were studied. Compared with patients who admitted to the ICU since symptoms onset ≤7 days (55.6%), patients who admitted to the ICU since symptoms onset >7 days (44.4%) were more likely to have extra-pulmonary complications (19 [95.0%] vs 16 [64.0%], P = .034), including acute kidney injury, cardiac injury, acute heart failure, liver dysfunction, gastrointestinal hemorrhage, hyperamylasemia, and hypernatremia. The incidence rates of acute respiratory distress syndrome, pneumothorax, and hospital-acquired pneumonia had no difference between the 2 groups. Except activated partial thromboplastin and Na+ concentration, the laboratory findings were worse in group of time from symptoms onset to ICU admission >7 days. There was no difference in mortality between the 2 groups. Of the 45 cases in the ICU, 19 (42.2%) were non-survivors, and 16 (35.6%) were with hospital-acquired pneumonia. Among these non-survivors, hospital-acquired pneumonia was up to 12 (63.2%) besides higher incidence of extra-pulmonary complications. However, hospital-acquired pneumonia occurred in only 4 (15.4%) survivors. Critically ill patients with COVID-19 who admitted to ICU at once might get benefit from intensive care via lower rate of extra-pulmonary complications.

ABSTRACT

Objective To explore the optimal therapy time for the treatment of severe coronavirus disease 2019(COVID-19)by traditional Chinese medicine(TCM)and its influence on the therapeutic effect and prognosis. Methods The clinical data,laboratory findings,and outcomes of 64 patients with severe COVID-19 treated with TCM and western medicine in Chongqing from January 20,2020, to March 11,2020 were retrospectively analyzed.Patients were divided into early intervention group[TCM was initiated within 3 days (including day 3) after the first diagnosis of severe type/critical type COVID-19]and late intervention group[TCM was initiated after 7 days (including day 7) after the first diagnosis of severe type /critical type COVID-19].The changes in clinical parameters during the course of disease were compared between the two groups. Results On day 14,the oxygenation index was 292.5(252.0,351.0)mmHg in the early intervention group,which was significantly higher than that in the late intervention group [246.0(170.0,292.5)mmHg](P=0.005).The length of hospital stay [(18.56±1.11)d vs.(24.87±1.64)d,P=0.001],duration of ICU stay [(14.12±0.91)d vs.(20.00±1.53)d,P=0.000] and time to negativity [(16.77±1.04)d vs.(22.48±1.66)d,P=0.001] in the early intervention group were significantly shorter than those in the late intervention group.The intubation rate(7.3%)in the early intervention group was significantly lower than that in the late intervention group(30.4%)(P=0.028). Conclusion Early TCM therapy within three days after a diagnosis of severe COVID-19 can shorten the length of hospital stay,duration of ICU stay,and time to negativity and decrease intubation rate.
