Accessible summary What is known on the subject? Coercive interventions (CI) in emergency psychiatry face increasing criticism, as they can be an emotional, even traumatic event for all persons involved. They are thus considered the last resort. The use of coercive interventions differs widely with regard to type and frequency of measures across different countries and institutions. Individual staff characteristics, such as attitudes towards coercion, may play a vital role in the management of aggression. Little is known about the influence of emotions of staff members on CI, but they are likely to play an important role. What the paper adds to existing knowledge? Most staff members surveyed had a rather critical view of coercion and considered it a “necessary evil.” Staff members with the most work experience had a more critical view of coercion in comparison with less experienced staff. Nurses rated coercion more positively than did psychiatrists or psychologists. Emotions play an important role in decision‐making processes. The current study systematically asked for accompanying emotions during the application of CI and looked for individual differences. A majority of the participants experienced compassion; about half felt helplessness, grief or anxiety. Almost 20% stated that they felt a sense of power. Older staff members more often felt anger or guilt; women felt less power than men did. Nurses felt more desperation than other occupational groups. Staff members consider reflective interventions, such as team supervisions or post‐seclusion/restraint debriefings with the patient, as important. Nevertheless, only half reported that these interventions are carried out routinely. Staff members believe that certain risk factors (including stress, low staffing, a fully occupied ward and the presence of particular staff members) enhance the probability of CI. What are the implications for practice? To reduce the use of coercive interventions, we recommend that psychiatric teams include highly experienced staff members as work experience has a positive effect on the attitudes towards coercive interventions. Structured post‐seclusion/restraint debriefings and team supervisions are considered helpful by staff members and are relatively easy to implement on acute wards. Enhancing staff members’ ability to reflect on their own attitudes, emotions and actions is likely to reduce coercive interventions. Abstract IntroductionLittle is known about staff attitudes towards coercive interventions (CI) and emotions accompanying these measures. AimThe current study assessed attitudes, views on reflective interventions and accompanying emotions of different occupational groups towards CI, as well as factors, that increase the probability of CI. MethodStaff members (N = 138) of a large psychiatric hospital in Germany were assessed using the Staff Attitude to Coercion Scale (SACS) and newly developed items assessing staff members’ emotions and views on coercion. ResultsExperienced staff members were most critical of co...

The flat panel-based volume computed tomography (fpVCT) is a new CT device applicable for experimental, three-dimensional evaluation of teeth at a resolution of about 150 microm in the high contrast region. The aim of this study was to investigate whether fpVCT was suitable for quantification of the volumes of dental hard tissues and the root canal system to establish a new method for morphological studies. Fifty-two extracted third molars (maxillary: 31, mandibular: 21) were examined with a prototype of an fpVCT using a volumetry algorithm at different levels according to the radiographic density of enamel and dentine. Volumetry of the root canal system was performed after "region growing segmentation": starting from a voxel in the centre of the root canal, this algorithm searches voxels of same density in the surrounding. The volumetry of the root canal system was stopped by the investigator at the apical constriction. Results showed that dentine, enamel and root canal system could be well distinguished in three-dimensional images. Volumetry yielded the following data (cm(3), mean+/-SD): dentine 0.438+/-0.111, enamel 0.227+/-0.051, root canal system 0.052+/-0.017 and total volume 0.753+/-0.159. In conclusion, the fpVCT is appropriate for non-destructive volumetry of large numbers of teeth in experimental laboratory studies.

BackgroundPsychological interventions are increasingly recommended as adjunctive treatments for psychosis, but their implementation in clinical practice is still insufficient. The individualized metacognitive therapy program (MCT+; www.uke.de/mct_plus) represents a low-threshold psychotherapeutic approach that synthesizes group metacognitive training (MCT) and cognitive behavioral therapy for psychosis, and addresses specific cognitive biases that are involved in the onset and maintenance of psychosis. It aims to “plant the seed of doubt” regarding rigid delusional convictions and to encourage patients to critically reflect, extend and change their approach to problem solving. Its second edition also puts more emphasis on affective symptoms. A recent meta-analysis of metacognitive interventions (MCT, MCT+) indicate small to moderate effects on positive symptoms and delusions, as well as high rates of acceptance. Nonetheless, no long-term studies of MCT+ involving large samples have been conducted.MethodsThe goal of the present multi-center, observer-blind, parallel-group, randomized controlled trial is to compare the efficacy of MCT+ against an active control (cognitive remediation; MyBrainTraining©) in 328 patients with psychosis at three time points (baseline, immediately after intervention [6 weeks] and 6 months later). The primary outcome is change in psychosis symptoms over the 6-month follow-up period as assessed by the delusion subscale of the Psychotic Symptom Rating Scale. Secondary outcomes include jumping to conclusions, other positive symptoms of schizophrenia, depressive symptoms, self-esteem, quality of life, and cognitive insight. The study also seeks to elucidate mediating factors that promote versus impede symptom improvement across time.DiscussionThis is the first multi-center randomized controlled trial to test the efficacy of individualized MCT+ in a large sample of patients with psychosis. The rationale for the trial, the design, and the strengths and limitations of the study are discussed.Trial RegistrationThe trial is registered through the German Clinical Trials Register (www.drks.de) as DRKS00008001.
