This article presents management processes for dealing with the novel coronavirus disease 2019 (COVID-19) outbreak at the West China Hospital of Sichuan University. From January to March 2020, the West China Hospital of Sichuan University established response structures and protocols, as well as integrated out-of-hospital resources, to deal with the COVID-19 outbreak. A total of 8066 patients were screened, and 345 COVID-19 patients were isolated for treatment. Hospital command systems, emergency management protocols, as well as process, space, and personnel management, strengthening material reserves, and social responsibility strategies were implemented. Outbreak management aspects that required improvement included estimates of the anticipated number of cases, timely collection of patient information and feedback on the effect of outreach and online consultation methods.
ABSTRACT IMPACT: Novel adipokines like tetranectin help explain why some people progress from obesity to diseases like diabetes, atherosclerosis, and dislipidemia OBJECTIVES/GOALS: Obesity has an established association with diabetes, dyslipidemia, and atherosclerosis. Preventing progression from obesity to insulin resistance requires understanding of the regulatory mechanisms involved in the loss of insulin sensitivity. Adipose tissue is well known to function as an endocrine organ that produces many kinds of adipokines. METHODS/STUDY POPULATION: Blood sample analysis from human patients and mice was used to determine associations between tetranectin and obesity. Samples were tested with a monoclonal anti-tetranectin antibody for detection with western blot. A tetranectin mutant knock out mouse line was compared to wild type littermates on high fat diet for 4 months. Insulin tolerance tests and glucose tolerance were used to determine progression to insulin resistance and glucose intolerance. Histological analysis of metabolic tissue was used to demonstrate adipocyte hypertrophy and liver steatosis. RESULTS/ANTICIPATED RESULTS: In the current study, we report the identification and initial characterization of a novel adipokine tetranectin. Tetranectin, which is coded by the C-type lectin domain family 3 member B (CLEC3B) gene, is ubiquitously expressed in various mouse tissues, whereas it is highly enriched in white adipose tissue. We found that the serum level of tetranectin was much higher in both obese and diabetic patients. Knocking out the tetranectin gene in mice protected against glucose intolerance in males but reduced insulin and glucose tolerance in females, without effects on food intake and body weight for either sex. Mechanistically, tetranectin targets liver tissues and its deficiency increases lipid accumulation in hepatocytes in females. DISCUSSION/SIGNIFICANCE OF FINDINGS: We have identified a novel adipokine which mediates a different metabolic crosstalk among tissues to maintain systemic glucose and lipid metabolism in different genders. Further investigation of tetranectin’s function could yield a new target for precise therapeutic treatment for obesity and its associated metabolic diseases in different genders
To date, we have only limited evidence of the determinants of earthquake inpatient mortality-related factors. This study is among the first to explore related factors of inpatient deaths using data from multiple hospitals and multiple earthquakes.
We included and retrospectively analyzed data on 32,976 earthquake inpatients in the West China Earthquake Patients Database. Of these, we analyzed the records of 284 patients who died during hospitalization. We collected 12 dichotomous variables with reference to previous reports: patients’ age (both ≤ 15 years and ≥ 65 years), gender, prehospital treatment, intensive care unit (ICU) admission, the presence of severe traumatic brain injury (TBI), trunk injury, severe poly-trauma, crush syndrome, multiple-system organ failure (MSOF), infection, and cardiac/respiratory disease. We performed multivariate logistic regression analysis to explore independent related factors of mortality.
Ultimately, we identified severe TBI, MSOF, old age (≥ 65 years), ICU admission, crush syndrome, and cardiac/respiratory disease as independent mortality-related factors. Severe TBI was the greatest risk factor of inpatient death (ods ratio [OR], 31.913, 95% confidence interval [CI], 20.484-49.720), followed by MSOF (OR 30.905, 95% CI, 21.733-43.947).
To reduce earthquake inpatient mortalities, the related factors analyzed in this study should be prioritized in future inpatient earthquake response strategies.
