ABSTRACT
Objective:To investigate the status and the influencing factors of influenza vaccination during the COVID-19 pandemic among community-dwelling elderly in Shanghai.Methods:A questionnaire survey on influenza vaccination among community-dwelling elderly was conducted in Shanghai Taikang elderly community in November 2020. The information on demographic characteristics, reasons for refusal of vaccination, and measures for increasing vaccination rates were collected. Multiple logistic regression was used to analyze the correlation between influenza vaccination and sociodemographic and health-related characteristics.Results:Among 520 respondents, the vaccination rate was 30.58% (159/520). Compared with unvaccinated group, elderly in vaccinated group was older ( t=16.04, P=0.003)and more educated(χ2=8.16, P=0.043). The elderly with comorbid heart disease, chronic obstructive pulmonary disease, tumor, asthma, Parkinson′s disease were likely to have vaccination ( OR=1.45, 2.16, 1.23, 1.64, 5.83; all P<0.05).The reasons for the elderly not to be vaccinated were concerns of side effects (46.26%, 167/361), lack of doctors′ recommendations (24.10%, 87/361), and unnecessary for people with good health conditions (19.39%, 70/361). The independent factors of influenza vaccine awareness rate were healthcare providers′ recommendations ( OR=9.18, 95% CI:5.47-16.32), vaccination at home( OR=11.79, 95% CI:6.87-21.66),vaccination available in community( OR=8.08, 95% CI:8.08-15.45),the mandatory requirement ( OR=4.61,95% CI:4.61-10.11),free of charge( OR=7.48, 95% CI:4.08-15.12). Conclusion:Influenza vaccination coverage among the elderly in Shanghai is still low even during the COVID-19 pandemic. Policy interventions, awareness education and strengthening the primary healthcare resources may contribute to achieving a high influenza vaccine coverage rate in the community-dwelling elderly
ABSTRACT
Objective To evaluate the predictive value of N-terminal-pro-brain natriuretic peptide (NT-proBNP) in weaning patients from mechanical ventilation (MV).Methods Data of 42 patients supported with MV in intensive care unit (ICU) admitted to the Rui Jin Hospital from January through December in 2014 were retrospectively analyzed,and the causes for MV were recorded.According to the outcomes of weaning from MV after 48 hours,the patients were divided into two groups namely success group and failure group.Comparisons of fluid balance in 72 hours before spontaneous breathing trial (SBT),and comparisons of NT-proBNP1 levels at admission,NT-proBNP2 levels before SBT,NT-proBNP3 levels after 48 hours after SBT between two groups were carried out.And the receiver operating characteristic (ROC) curve for predicting weaning rate was plotted to find the optimal cut-off point of NT-proBNP2.Results In the total of 42 patients,there were 27 cases in success group and 15 cases in failure group.There were not statistically differences of NT-proBNP1 levels between success group and failure group (P =0.121).However,the NT-proBNP2 levels and NT-proBNP3 levels in failure group were significantly higher than those in success group (P =0.01,0.003).The area under curve (AUC) of the ROC curve of NT-proBNP2 levels to predict the failure of weaning was 0.862 (95％ CI:0.753-0.971).When the optimal cut-off point of NT-proBNP2 was 715.5 pg/mL,the sensitivity and specificity were 93.3％ and 74.1％,respectively.Conclusion The NT-proBNP2 levels before SBT have predictive value in weaning rate,and it can be used as one of the screening indicators for weaning.
ABSTRACT
Objective To investigate the characteristics of the road traffic accident (RTA) casualties in Shanghai in 2003.Methods.The characteristics of RTA casualties were analyzed retrospectively on the data of Public Security Bureau and other related information.Results There were 54 197 RTA cases in 2003 with 1 406 death and 11 178 injured.The incidence rate and fatality of RTA was 311.48/10~4 and 11.17% respectively.The vehicle or population injury rate and mortality were 64.24/10~4,8.08/10~4,83.31/10~5 and 10.48/10~5,respectively.The fatality of suburb was higher than that of urban.Most of the casualties were bicyclist,pedestrians and motorcyclist,ranged mainly from 21 to 50 years old. Head injury and multiple traumas were the leading cause of death.Conclusion The RTA related injury had become a public health problem.The key strategies to decrease the fatality and disability of RTA were to propagandize the traffic safety perception in citizen and enforce the construction of rescue system for RTA including the EMSS.
