ABSTRACT

Objective: The main aim of this study was to investigate the prevalence and risk factors of adult self-reported allergic rhinitis and asthma in plain lands and hilly areas of Shenmu City in China, and analyze the differences between regions. Methods: The multi-stage stratified random sampling was applied in a cross-sectional survey of adult residents in Shenmu City, from September to December 2019. The unconditional logistic regression analysis was used to screen the influence factors of allergic rhinitis and asthma. Results: 4,706 adults participated in the survey, and 99% (4,655 in 4,706) completed the questionnaires. The prevalence of allergic rhinitis was 25.4%, and the prevalence of asthma was 9.4%. The prevalence of the allergic rhinitis without asthma, asthma without allergic rhinitis, and the combined allergic rhinitis with asthma were 18.9, 2.9, and 6.5%, respectively. The prevalence of allergic rhinitis and asthma existed regional differences. The prevalence of adult self-reported allergic rhinitis was 41.5% in plain lands areas and 22.1% in hilly areas. The prevalence of adult self-reported asthma was 12.8% in plain lands and 8.8% in hilly areas. The prevalence of allergic rhinitis and asthma existed seasonal differences, with the highest prevalence from July to September. The analysis of risk factors showed that higher education [middle and high school (OR 1.72, 95%CI 1.42-2.07); college and above (OR 2.67, 95%CI 1.99-3.59)], comorbidities of other allergic diseases (OR 3.90, 95%CI 3.23-4.70), family history of allergies (OR 2.89, 95%CI 2.36-3.53), and plain lands areas (OR 2.51, 95%CI 2.06-3.05) were the risk factors for the allergic rhinitis without asthma. Aging [40-49 years old (OR 4.29, 95%CI 1.02-18.13); 50-59 years old (OR 5.89, 95%CI 1.40-24.76); ≥60 years old: (OR 6.14, 95%CI 1.41-26.71)], never-smokers (OR 1.66, 95%CI 0.99-2.80), comorbidities of other allergic disorders (OR 2.17, 95%CI 1.42-3.32), and family history of allergies (OR 2.20, 95%CI 1.40-3.47) were the risk factors for the asthma without allergic rhinitis. Advanced age [30-39 years (OR 2.16, 95%CI 1.23-3.82); 40-49 years (OR 2.86, 95%CI 1.56 to 5.25); 50-59 years (OR 2.95, 95%CI 1.58-5.51); ≥60 years old (OR 2.27, 95%CI 1.09-4.72)], higher education [middle and high school (OR 2.23, 95%CI 1.62-3.07); college and above (OR 4.28, 95%CI 2.72-6.74)], non-agricultural workers (OR 1.70, 95%CI 1.18-2.43),never-smokers (OR 2.26, 95%CI 1.51-3.39), comorbidities of other allergic diseases (OR 4.45, 95%CI 3.37-5.88), family history of allergies (OR 5.27, 95%CI 3.98-6.97), and plain lands areas (OR 2.07, 95%CI 1.51-2.86) were the risk factors for the combined allergic rhinitis with asthma. Conclusions: The prevalence of allergic rhinitis and asthma in Shenmu City was relatively high, with regional differences. Genetic and environmental factors were the important risk factors associated with allergic rhinitis and asthma. Our research would provide data support for preventing and controlling allergic rhinitis and asthma in this region in the future, and appropriate prevention and control programs should be formulated according to the characteristics of different regions.

ABSTRACT

Background: COVID-19 has caused more than 2.6 billion infections and several million deaths since its outbreak 2 years ago. We know very little about the long-term cellular immune responses and the kinetics of neutralizing antibodies (NAbs) to SARS-CoV-2 because it has emerged only recently in the human population. Methods: We collected blood samples from individuals who were from the first wave of the COVID-19 epidemic in Wuhan between December 30, 2019, and February 24, 2020. We analyzed NAbs to SARS-CoV-2 using pseudoviruses and IgG antibodies to SARS-CoV-2 spike (S) and nucleocapsid (N) protein using enzyme-linked immunosorbent assay in patients' sera and determined SARS-CoV-2-specific T-cell responses of patients with ELISpot assays. Results: We found that 91.9% (57/62) and 88.9% (40/45) of COVID-19 patients had NAbs against SARS-CoV-2 in a year (10-11 months) and one and a half years (17-18 months), respectively, after the onset of illness, indicating that NAbs against SARS-CoV-2 waned slowly and possibly persisted over a long period time. Over 80% of patients had IgG antibodies to SARS-CoV-2 S and N protein one and a half years after illness onset. Most patients also had robust memory T-cell responses against SARS-CoV-2 one and a half years after the illness. Among the patients, 95.6% (43/45) had an IFN-γ-secreting T-cell response and 93.8% (15/16) had an IL-2-secreting T-cell response. The T-cell responses to SARS-CoV-2 were positively correlated with antibodies (including neutralizing antibodies and IgG antibodies to S and N protein) in COVID-19 patients. Eighty percent (4/5) of neutralizing antibody-negative patients also had SARS-CoV-2-specific T-cell response. After long-term infection, protective immunity was independent of disease severity, sex, and age. Conclusions: We concluded that SARS-CoV-2 infection elicited a robust and persistent neutralizing antibody and memory T-cell response in COVID-19 patients, indicating that these sustained immune responses, among most SARS-CoV-2-infected people, may play a crucial role in protection against reinfection.

ABSTRACT

AIMS AND OBJECTIVES: This study aimed to clarify the attitudes, knowledge and vaccination willingness of patients with chronic diseases toward COVID-19 vaccines and the influencing factors. BACKGROUND: Vaccination against COVID-19 is an important way to protect patients with chronic diseases, but the vaccination acceptance varies across diseases and populations. A better understanding of this condition will lead to tailored intervention strategies and high vaccination rates. DESIGN: Cross-sectional study. METHODS: Data were collected between March 2021 and May 2021 in China. A self-compiled questionnaire was used in the survey. Two independent-samples t-tests/one-way analysis of variance or U test/H test was used to measure the differences between groups. Multivariate regression analysis was used to identify the influencing factors. The study adhered to the EQUATOR checklist, STROBE. RESULTS: A total of 998 patients participated in the study. Score rates of attitudes, knowledge and vaccination willingness were 69.9%, 68.4% and 70.6% respectively. Age, vaccination status of family members, education levels, vaccine side effects and economic level were positive factors that could influence patients' vaccination acceptances, while time of illness, type of disease and political affiliations were negative predictors. The top reasons for willingness toward vaccination were supporting national strategies, belief on the vaccines and fearing of contracting COVID-19, while physical reasons, side effects and having a wait-and-see attitude were unwillingness factors. CONCLUSIONS: Patients' attitudes, knowledge and vaccination willingness were medium. Nurses should pay attention to patients who are from lower socioeconomic backgrounds, under 30 or over 70 years old, have no political affiliations, have damage to vital organs, have a long course of illness, family members have not received COVID-19 vaccines and had no side effects after receiving other vaccines. RELEVANCE TO CLINICAL PRACTICE: Clinical nurses are recommended to take measures from patients' duration of illness, damaged organs, demographic characteristics and families to improve patients' vaccination acceptances.

ABSTRACT

BACKGROUND: Appropriate allocation of nursing staff is key to ensuring efficient nursing in hospitals, and is significantly correlated with patient safety, nursing quality, and nurse job satisfaction. However, there are few studies on nursing workforce allocation in the isolation wards of COVID-19 designated hospitals globally. This study aims to better understand the nursing workforce allocation in the isolation wards of COVID-19 designated hospitals in China, and provide a theoretical basis for efficiently deploying first-line nurses in China and across the world in the future. METHODS: An online survey was conducted among the head nurses (n = 229) and nurses (n = 1378) in the isolation wards of 117 hospitals (selected by stratified sampling), using a self-reported human resource allocation questionnaire. RESULTS: The average bed-to-nurse ratios of different isolation wards were different (Z = 36.742, P = 0.000). The bed-to-nurse ratios of the ICU, suspected COVID-19 cases ward, and confirmed COVID-19 cases ward, were 1:1.88, 1:0.56, and 1:0.45, respectively. The nurse work hours per shift in different isolation wards were also different (Z = 8.468, P = 0.014), with the specific values of the ICU, suspected COVID-19 cases ward, and confirmed COVID-19 cases ward, being 5, 6, and 6 h, respectively. A correlation analysis showed that the average work hours per shift was proportional to the overtime work of nurses (rs = 0.146), the proportion of nurse practitioners was proportional to the overall utilization rate of nursing human resources in the wards (rs = 0.136), and the proportion of nurses with college degrees was proportional to teamwork (rs = 0.142). The proportion of nurses above grade 10 was inversely proportional to teamwork and psychological problems (rs = 0.135, rs = 0.203). The results of multiple stepwise regression analyses showed that the work hours of nurses per shift was the main factor affecting nurse satisfaction and that the proportion of nurses and the work hours of nurses per shift were both independent factors affecting the length of stay (LOS) of patients. CONCLUSION: Hospitals in China have made good nursing workforce allocations during the COVID-19 pandemic, but there are certain shortcomings. Therefore, scientific and efficient nursing workforce allocation practice plans should be established to improve the ability of hospitals to deal with public health emergencies and are urgent problems that need to be addressed soon.

ABSTRACT

The emerging coronavirus diseases such as COVID-19, MERS, and SARS indicated that animal coronaviruses (CoVs) spillover to humans are a huge threat to public health. Therefore, we needed to understand the CoVs carried by various animals. Wild hedgehogs were collected from rural areas in Wuhan and Xianning cities in Hubei Province for analysis of CoVs. PCR results showed that 5 out of 51 (9.8%) hedgehogs (Erinaceus amurensis) were positive to CoVs in Hubei Province with 3 samples from Wuhan City and 2 samples from Xianning City. Phylogenetic analysis based on the partial sequence of RNA-dependent RNA polymerase showed that the CoVs from hedgehogs are classified into Merbecovirus of the genus Betacoronavirus; the hedgehog CoVs formed a phylogenetic sister cluster with human MERS-CoVs and bat MERS-related CoVs. Among the 12 most critical residues of receptor binding domain in MERS-CoV for binding human Dipeptidyl peptidase 4, 3 residuals were conserved between the hedgehog MERS-related CoV obtained in this study and the human MERS-CoV. We concluded that hedgehogs from Hubei Province carried MERS-related CoVs, indicating that hedgehogs might be important in the evolution and transmission of MERS-CoVs, and continuous surveillance of CoVs in hedgehogs was important.
