In this paper, we analyzed the responses of DOC patients to habit stimulation. Nineteen DOC patients with alcohol consumption or smoking habits were recruited and 64-channel EEG signals were acquired both at the resting state and at three stimulation states. Wavelet transformation and nonlinear dynamics were used to extract the features of EEG signals and four brain lobes were selected to investigate the degree of EEG response to habit stimulation. Results showed that the highest degree of EEG response was from the callname stimulation, followed by habit and music stimulations. Significant differences in EEG wavelet energy and response coefficient were found both between habit and music stimulation, and between habit and call-name stimulation. These findings prove that habit stimulation induces relatively more intense EEG responses in DOC patients than music stimulation, suggesting that it may be a relevant additional method for eliciting patient arousal. 展开更多

Background:Financial issues are major barriers for rural-to-urban migrants accessing tuberculosis(TB)care in China.This paper discusses the effectiveness of providing financial incentives to migrant TB patients(with a focus on poor migrants in one district of Shanghai using treatment completion and default rates),the effect of financial incentives in terms of reducing the TB patient cost,and the incremental cost-effectiveness ratio of the intervention.Results:Ninety and ninety-three migrant TB patients were registered in the intervention and control districts respectively.TB treatment completion rates significantly improved by 11%(from 78%to 89%)in the intervention district,compared with only a 3%increase(from 73%to 76%)in the control district(P=0.03).Default rates significantly decreased by 11%(from 22%to 11%)in the intervention district,compared with 1%(from 24%to 23%)in the control district(P=0.03).In the intervention district,the financial subsidy(RMB 1,080/US$170)accounted for 13%of the average patient direct cost(RMB 8,416/US$1,332).Each percent increase in treatment completion costs required an additional RMB 6,550(US$1,301)and each percent reduction in defaults costs required an additional RMB 5,240(US$825)in the intervention district.Conclusions:Overall,financial incentives proved to be effective in improving treatment completion and reducing default rates among migrant TB patients in Shanghai.The results suggest that financial incentives can be effectively utilized as a strategy to enhance case management among migrant TB patients in large cities in China,and this strategy may be applicable to similar international settings. 展开更多
