An intervention with clinical application must be effective and safe, therefore, when evaluating interventions, the benefit-harm ratio should be considered, and only those interventions with more benefits than harms have application value. To evaluate the benefits and harms of an intervention evidence of both benefits and harms should be reported in clinical trials. To promote better reporting of harms in randomized controlled trials, the CONSORT group had added an entry on harms in the 2001 version of the CONSORT statement, and then in 2004, the CONSORT group developed the CONSORT Harms extension; however, it has not been consistently applied and needs to be updated, the reporting of harms is still inadequate. The CONSORT group has updated《Better reporting of harms in randomized trial: an extension of the CCONSORT statement.》, published《CONSORT Harms 2022 statement, explanation, and elaboration: updated guideline for the reporting of harms in randomized trials》. This article presents and explains the Harms 2022, with the aim of helping researchers better understand and use the statement, with a view to improving the reporting quality of harms in clinical trials.
The development and potential application of brain-computer interface (BCI) technology is closely related to the human brain, so that the ethical regulation of BCI has become an important issue attracting the consideration of society. Existing literatures have discussed the ethical norms of BCI technology from the perspectives of non-BCI developers and scientific ethics, while few discussions have been launched from the perspective of BCI developers. Therefore, there is a great need to study and discuss the ethical norms of BCI technology from the perspective of BCI developers. In this paper, we present the user-centered and non-harmful BCI technology ethics, and then discuss and look forward on them. This paper argues that human beings can cope with the ethical issues arising from BCI technology, and as BCI technology develops, its ethical norms will be improved continuously. It is expected that this paper can provide thoughts and references for the formulation of ethical norms related to BCI technology.
Objective To investiget the necessity of carrying out the education of Tobacco Hazards and Prevention and Control in Chinese universities, and explore the teaching mode of Tobacco Hazards and Prevention and Control suitable for college students, so as to improve the teaching quality and the awareness level of Chinese college students on tobacco hazards. Methods A public elective course on Tobacco Hazards and Prevention and Control was set up in Sichuan University with the teaching mode of scientific popularization education, combining theory and practice. The 43 college students who had completed the public elective course on Tobacco Hazards and Prevention and Control in the autumn semester of 2022 were retrospectively included as the research group (the elective group), and 43 college students who did not take this course in the same period were included as the control group (the non-elective group) by the method of quota sampling. Questionnaire survey was adopted to investigate the basic information, personal and family smoking situation of the two groups of students, evaluate the purpose of taking this course, satisfaction with the course, and mastery of knowledge related to tobacco epidemiology of the students who had completed the course, and compare the awareness of tobacco hazards and the attitude toward tobacco prevention and control between the two groups. Results There was no significant difference in age, gender, education level, place of student source, personal smoking situation, family smoking situation, or secondhand smoking exposure between the two groups (P>0.05). In the elective group, 58.1% of the students chose the course due to their personal interests, and 74.4% of the students were very satisfied with the course. The awareness rates of smoking causing myocardial infarction (97.7% vs. 72.1%) and stroke (97.7% vs. 81.4%), secondhand smoking causing heart disease in adults (97.7% vs. 76.7%), and “low tar not equaling to low hazard” (86.0% vs. 37.2%) in the elective group were significantly higher than those in the non-elective group (P<0.05). The rates of awareness of E-cigarettes being harmful to health and supportive attitude toward smoking being forbidden in public places were high in both groups (P>0.05). Conclusion Carrying out the public elective course on Tobacco Hazards and Prevention and Control in comprehensive universities with the teaching mode of popularizing science education and combining theory and practice can improve the theoretical knowledge and awareness level of college students related to tobacco, which is of great significance to improving the tobacco prevention and control awareness of college students.
Statistical graph is an indispensable part of scientific papers. It is helpful to promote the communication, dissemination, and application of academic achievements by presenting research results intuitively and accurately through standardized and beautiful visual graphs. The safety of a medical intervention is the basic premise of its clinical application, and randomized controlled trial (RCT) as an important design to determine the efficacy and safety of medical interventions, it is extremely important to accurately present the information on the safety outcomes of interventions found therein. However, the research found that the reports of RCTs didn’t adequately use visual graphs to present harms data. In order to promote clinical researchers to better use visual graphs to present harms data, international scholars recently published a consensus study in BMJ, which identified and recommended 10 statistical graphs for presenting harms data in RCTs. In order to facilitate domestic scholars to understand and apply the consensus, this article interprets the consensus and recommendations, and it is expected to provide help for improving the quality of harms visualization in domestic papers of RCTs.
