MR-safety in clinical practice at 7T: Evaluation of a multistep screening process in 1819 subjects

IntroductionMR facilities must implement and maintain adequate screening and safety procedures to ensure safety during MR examinations. The aim of this study was to evaluate a multi-step MR safety screening process used at a 7T facility regarding incidence of different types of safety risks detected during the safety procedure.MethodsSubjects scheduled for an MR examination and having entered the 7T facility during 2016–2019 underwent a pre-defined multi-step MR safety screening process. Screening documentation of 1819 included subjects was reviewed, and risks identified during the different screening steps were compiled. These data were also related to documented decisions made by a 7T MR safety committee and reported MR safety incidents.ResultsPassive or active implants (n = 315) were identified in a screening form and/or an additional documented interview in 305 subjects. Additional information not previously self-reported by the subject, regarding implants necessitating safety decisions performed by the staff was revealed in the documented interview in 102 subjects (106 items). In total, the 7T MR safety committee documented a decision in 36 (2%) of the included subjects. All of these subjects were finally cleared for scanning.ConclusionA multi-step screening process allows a thorough MR screening of subjects, avoiding safety incidents. Different steps in the process allow awareness to rise and items to be detected that were missed in earlier steps.Implications for practiceSafety questions posed at a single timepoint during an MR screening process might not reveal all safety risks. Repetition and rephrasing of screening questions leads to increased detection of safety risks. This could be effectively mitigated by a multi-step screening process. A multi-disciplinary safety committee is efficient at short notice responding to unexpected safety issues.     

371名大学生微信朋友圈人格、自我呈现策略与情绪表达的关系

目的 探究大学生微信朋友圈人格、自我呈现策略和情绪表达间的关系。方法 采用社交网络自我呈现策略问卷、艾森克人格问卷简式量表、伯克利情绪表达问卷,对随机抽取的371名大学生进行调查。结果 ⑴外倾型人格总分与真实自我呈现策略总分呈正相关(r=0.170,P=0.001),与正性情绪表达呈正相关(r=0.166,P=0.001),与情绪表达强度呈正相关(r=0.184,P=0.001),真实自我呈现策略与正性情绪表达呈正相关(r=0.239,P=0.001)。⑵真实自我呈现策略在外倾型人格与正性情绪表达的关系中存在部分中介效应。结论 371名大学生的外倾型人格、真实自我呈现策略与正性情绪表达关系密切,真实自我呈现策略在外倾型人格与正性情绪表达的关系中存在部分中介效应。     

广西高校新生对HIV尿液自助采样包的使用意愿及关注因素调查

目的 了解广西高校新生对HIV尿液自助采样包的使用意愿及关注因素,为进一步在高校开展HIV尿液自我采样传递检测提供依据和参考。 方法 采取整群随机抽样方法,分别选取广西A、B两所高校新生进行匿名问卷调查,其中,A校在健康教育讲座前问卷调查,B校在健康教育讲座后问卷调查。 结果 本次调查中,共发放问卷500份,A、B两所高校新生的问卷回收率分别是88.0%(132/150),96.9%(339/350),差异有统计学意义(P<0.001)。A、B两所高校新生艾滋病基本知识平均知晓率分别为73.7%,87.7%,差异有统计学意义(P<0.001)。受访的大学新生中有2.3%(11/471)曾接受过HIV检测。A、B两所高校新生对HIV尿液自助采样包的使用意愿率分别是63.6%(84/132),88.5%(300/339),差异有统计学意义(P<0.001)。男生对HIV尿液自助采样包的使用意愿率均要稍高于女生,但差异无统计学意义(P>0.05)。在阻碍HIV尿液自助采样包的使用因素调查中,54.0%(47/87)认为操作流程不方便,37.9%(33/87)怀疑结果的准确性,8.1%(7/87)认为容易污染。此外,在大学新生对HIV尿液自助采样包的关注因素调查中,首要关注的是保密性(85.4%,402/471),其次是准确性(72.4%,341/471)。超过一半的新生认为100~150元是HIV尿液自助采样包的可接受价格范围,高达97%的新生认为检测结果的反馈时长应小于7 d。 结论 广西高校新生对HIV尿液自助采样包的态度积极,使用意愿较高,对HIV尿液自我采样传递检测持相对开放态度。HIV尿液自助采样包的保密性和准确性是大学新生最为关注的两个因素。举办健康教育讲座对HIV尿液自助采样包进行适当的介绍和宣传,可有效提高使用意愿。

Negative mood as a mediator of the association between insomnia severity and marijuana problems in college students

Insomnia symptoms have been linked to problematic marijuana use among young adults, but the mechanism underlying this association and whether sex differences exist, remains unclear. Using cross‐sectional data, this study examined negative mood as a mediator of the association between insomnia and marijuana problems among male and female college students. Undergraduate students (n = 267; 61% female) reporting marijuana use in the past month completed an online survey assessing insomnia symptoms, negative mood and marijuana problems. Controlling for relevant covariates, negative mood was examined as a mediator of the association between insomnia and marijuana problems using bootstrapped significance tests for indirect effects (n‐boot = 1,000). Results indicated that higher levels of insomnia were associated with greater levels of negative mood (regardless of sex), which in turn were associated with greater marijuana‐related problems. In conclusion, insomnia symptoms are associated with more negative mood among college students who use marijuana, and this effect on negative mood accounts for a large part of the association of insomnia symptoms with marijuana‐related problems. Research is needed to determine if these associations are maintained prospectively.
