Crisis-planning interventions for people with psychotic illness or bipolar disorder: systematic review and meta-analyses.

BACKGROUND: Mental health services lack a strong evidence base on the most effective interventions to reduce compulsory admissions. However, some research suggests a positive impact of crisis-planning interventions in which patients are involved in planning for their future care during a mental health crisis. AIMS: This review aimed to synthesise randomised controlled trial (RCT) evidence on the effectiveness of crisis-planning interventions (for example advance statements and joint crisis plans) in reducing rates of compulsory hospital admissions for people with psychotic illness or bipolar disorder, compared with usual care (PROSPERO registration number: CRD42018084808). METHOD: Six online databases were searched in October 2018. The primary outcome was compulsory psychiatric admissions and secondary outcomes included other psychiatric admissions, therapeutic alliance, perceived coercion and cost-effectiveness. Bias was assessed using the Cochrane collaboration tool. RESULTS: The search identified 1428 studies and 5 RCTs were eligible. One study had high risk of bias because of incomplete primary outcome data. Random-effects meta-analysis showed a 25% reduction in compulsory admissions for those receiving crisis-planning interventions compared with usual care (risk ratio 0.75, 95% CI 0.61-0.93, P = 0.008; from five studies). There was no statistical evidence that the intervention reduced the risk of voluntary or combined voluntary and compulsory psychiatric admissions. Few studies assessed other secondary outcomes. CONCLUSIONS: Our meta-analysis suggests that crisis-planning interventions substantially reduce the risk of compulsory admissions among individuals with psychotic illness or bipolar disorder. Despite common components, interventions varied in their content and intensity across the trials. The optimal models and implementation of these interventions require further investigation. DECLARATION OF INTEREST: E.M., S.L., S.J. and B.L.-E. received funding from the National Institute for Health Research during the conduct of the study.

Mental health crisis resolution teams and crisis care systems in England: a national survey.

Aims and methodA national survey investigated the implementation of mental health crisis resolution teams (CRTs) in England. CRTs were mapped and team managers completed an online survey. RESULTS: Ninety-five per cent of mapped CRTs (n = 233) completed the survey. Few CRTs adhered fully to national policy guidelines. CRT implementation and local acute care system contexts varied substantially. Access to CRTs for working-age adults appears to have improved, compared with a similar survey in 2012, despite no evidence of higher staffing levels. Specialist CRTs for children and for older adults with dementia have been implemented in some areas but are uncommon.Clinical implicationsA national mandate and policy guidelines have been insufficient to implement CRTs fully as planned. Programmes to support adherence to the CRT model and CRT service improvement are required. Clearer policy guidance is needed on requirements for crisis care for young people and older adults.Declaration of interestNone.

Sarcasm and emoticons: Comprehension and emotional impact.

Most theorists agree that sarcasm serves some communicative function that would not be achieved by speaking directly, such as eliciting a particular emotional response in the recipient. One debate concerns whether this kind of language serves to enhance or mute the positive or negative nature of a message. The role of textual devices commonly used to accompany written sarcastic remarks is also unclear. The current research uses a rating task to investigate the influence of textual devices (emoticons and punctuation marks) on the comprehension of, and emotional responses to, sarcastic versus literal criticism and praise, for both unambiguous (Experiment 1) and ambiguous (Experiment 2) materials. Results showed that sarcastic criticism was rated as less negative than literal criticism, and sarcastic praise was rated as less positive than literal praise, suggesting that sarcasm serves to mute the positive or negative nature of the message. In terms of textual devices, results showed that emoticons had a larger influence on both comprehension and emotional impact than punctuation marks.

Multiple sclerosis: a review of the disease and treatment options.

OBJECTIVE: To provide a review of the etiology, epidemiology, clinical features, diagnostic findings, and treatment options for multiple sclerosis (MS). DATA SOURCES: A PubMed search of English language articles using a combination of words: elderly; multiple sclerosis*, late onset multiple sclerosis*, etiology; screening; diagnosis; or treatment to identify original studies, guidelines, and reviews on multiple sclerosis and late-onset multiple sclerosis, published 2002 to 2013. Primary sources were then used to search for additional relevant material. STUDY SELECTION AND DATA EXTRACTION: Original studies, clinical reviews, references, and guidelines were obtained and evaluated for their clinical relevance. DATA SYNTHESIS: The literature included guidelines and considerations for the etiology, diagnosis, screening, and management of MS. CONCLUSION: MS is a chronic autoimmune disease characterized by inflammation, demyelination, and local axonal injury. It typically presents between ages 20 and 40 and largely affects women. However, 2% to 10% of individuals are diagnosed after 50 years of age. Diagnosis is based on presentation of clinical symptoms and the McDonald criteria for diagnosing MS. Management focuses on suppression of the immune system and prevention of relapses.

Conductance sizing balloon for measurement of peripheral artery minimal stent area.

BACKGROUND: Because stent underdeployment occurs frequently, accurate minimal stent area (MSA) measurement during postdilatation is necessary. This study investigated the accuracy and repeatability for MSA determination using a novel conductance balloon (CB) catheter for peripheral vessels. METHODS: The CB catheter is a standard balloon catheter that measures electrical conductance (ratio of current/voltage drop) in real-time during inflation, which directly relates to the balloon cross-sectional area through Ohm's law. CB measurements were made in 4- to 10-mm phantoms on the bench, ex vivo in stents fully deployed in diseased human peripheral arteries, and in vivo in stents fully deployed in peripheral vessels in six swine. CB measurement accuracy and repeatability were calculated and compared with the known dimension (bench phantoms) or with intravascular ultrasound (IVUS) measurement after stent deployment (ex vivo and in vivo). RESULTS: CB measurements were highly accurate (error: 1.8% bench, 5% ex vivo, and 5% in vivo) and repeatable (error: 0.9% bench, 1.8% ex vivo, and 1.3% in vivo), with virtually no bias (average difference in measurements: -0.05 mm bench CB vs known phantom diameters, -0.06 mm ex vivo CB vs IVUS, and -0.11 mm in vivo CB vs IVUS). CONCLUSIONS: The CB sizing capability can be integrated within a standard balloon catheter (two-in-one function) to provide accurate, real-time assessment of MSA to ensure full stent apposition rather than the use of pressure as a surrogate for size.
