ABSTRACT
Objective@#To investigate the association of sleep quality, depressive symptoms and their interaction with non suicidal self injury (NSSI) among rural middle school students, so as to provide a reference for early prevention and control of NSSI among rural middle school students.@*Methods@#A multi stage cluster sampling method was used to randomly select four rural middle schools in Xuzhou, Jiangsu Province. A total of 1 723 middle school students were investigated according to the principle of grade stratification and class random selection. Paper questionnaires (including demographic factors, Non Suicidal Self Injury Short Scale, Pittsburgh Sleep Quality Index, Patient Health Questionnare-9) were used to conduct the questionnaire survey. Logistic regression model was used to analyze the association of sleep quality, depressive symptoms and their interaction with NSSI among rural middle school students.@*Results@#Totally 30.5% of middle school students had NSSI. Univariate results showed that girls (33.0%) had a higher incidence of NSSI than boys(27.3%), and those with sleep disorders and depressive symptoms had a higher incidence of NSSI, which was 46.8%, 43.6%. The results of multivariate Logistic regression showed that the risk of NSSI in students with sleep disorder was 1.80 times that in those without sleep disorder( OR 95%CI=1.42-2.28, P <0.01). The risk of NSSI in students with depressive symptoms was 3.32 times higher than that in those without depressive symptoms( OR 95%CI=2.60-4.24, P <0.01). The interaction results showed that there was additive interaction between sleep disturbance and depressive symptoms on the occurrence of NSSI behavior in rural middle school students, and the relative excess risk, attributable proportion and synergy index were 1.80, 0.30 and 1.57, respectively.@*Conclusion@#Sleep disorder and depressive symptoms are risk factors for NSSI among rural middle school students, and there is additive interaction between them.
ABSTRACT
AbstractObjective:The aim of the current study was to evaluate the early experience of the application of transcatheter aortic valve implantation with the balloon-expandable system in China. The transcatheter aortic valve implantation technology has been widely used for patients with inoperable severe aortic stenosis in the developed world. The application of transcatheter aortic valve implantation is still in the early stages of testing in China, particularly for the balloon-expandable valve procedure.Methods:This was a retrospective study. All patients undergoing transcatheter aortic valve implantation with balloon-expandable system in our hospital between 2011 and 2014 were included. Edwards SAPIEN XT Transcatheter Heart Valve was used. The improvement of valve and heart function was evaluated as well as 30-day mortality and major complications according to the VARC-2 definition.Results:A total of 10 transcatheter aortic valve implantation procedures with the balloon-expandable system were performed in our hospital, of which 9 were transfemoral and 1 was transapical. The median age was 76 years, and the median STS score and Logistic EuroSCORE (%) were 8.9 and 16.2. The implantation was successfully conducted in all patients, only 2 patients had mild paravalvular leak. There was no second valve implantation. Moreover, no 30-day mortality or complications was reported. Following the transcatheter aortic valve implantation procedure, the heart and valve functions had improved significantly. During the follow-up period of 3-34 months, one patient died of lung cancer 13 months after the operation.Conclusion:This early experience has provided preliminary evidence for the safety and efficacy of transcatheter aortic valve implantation procedure with the balloon-expandable system in the developing world with an increasing aging population.
ResumoObjetivo:O objetivo do presente estudo foi avaliar a experiência inicial da aplicação do implante percutâneo da válvula aórtica com o sistema balão-expansível na China. A tecnologia TAVI tem sido amplamente utilizada para pacientes com estenose aórtica grave inoperável no mundo desenvolvido. A aplicação de implante percutâneo da válvula aórtica está ainda nas etapas iniciais de teste na China, em particular o procedimento de válvula balão-expansível.Métodos:O estudo foi retrospectivo e todos os pacientes submetidos a implante percutâneo da válvula aórtica com sistema balão-expansível em nosso hospital entre 2011 e 2014 foram incluídos. Edwards SAPIEN XT Válvula Cardíaca Transcatheter foi usado. A melhoria do funcionamento da válvula e do coração foi avaliada, bem como mortalidade em 30 dias e as principais complicações de acordo com a definição VARC-2.Resultados:Um total de 10 procedimentos Tavi com o sistema balão-expansível foram realizados em nosso hospital, dos quais 9 foram transfemorais e 1 foi transapical. A idade média foi de 76 anos, e os STS mediana marcar e Logistic EuroSCORE (%) foram de 8,9 e 16,2. A implantação foi realizada com sucesso em todos os pacientes, apenas 2 pacientes tiveram vazamento paravalvar leve. Não houve um futuro implante valvar. Além disso, mortalidade em 30 dias ou complicações não foram relatadas. Seguindo o procedimento de implante percutâneo da válvula aórtica, as válvulas cardíacas e funções melhoraram significativamente. Durante o período de acompanhamento de 3-34 meses, um paciente morreu de câncer de pulmão 13 meses após a operação.Conclusão:Esta experiência inicial apresentou elementos de prova preliminar para a segurança e eficácia do procedimento implante percutâneo da válvula aórtica com o sistema balão-expansível no mundo em desenvolvimento com crescente envelhecimento da população.
