BackgroundGastrointestinal side effects are particularly common with clozapine and occur with other antipsychotics, ranging from mild constipation to fatal bowel obstruction and/or ischemia. While this adverse-effect spectrum has been attributed to ‘gastrointestinal hypomotility’, gastrointestinal transit times in antipsychotic-treated patients have not previously been measured, making this mechanism speculative.MethodsUsing standardized radiopaque marker (‘Metcalf’) methods we established colonic transit times of antipsychotic-treated psychiatric inpatients and compared them with population normative values. We analyzed results by antipsychotic type, antipsychotic dose equivalent, anticholinergic load, duration of treatment, gender, ethnicity, and age.OutcomesFor patients not prescribed clozapine, median colonic transit time was 23 h. For patients prescribed clozapine, median transit time was 104.5 h, over four times longer than those on other antipsychotics or normative values (p < 0.0001). Eighty percent of clozapine-treated patients had colonic hypomotility, compared with none of those prescribed other antipsychotics (olanzapine, risperidone, paliperidone aripiprazole, zuclopenthixol or haloperidol). In the clozapine group, right colon, left colon and rectosigmoid transit times were all markedly abnormal suggesting pan-colonic pathology. Hypomotility occurred irrespective of gender, age, ethnicity, or length of clozapine treatment. Transit times were positively correlated with clozapine plasma level (rho = 0.451, p = 0.045), but not with duration of treatment, total antipsychotic load or demographic factors.InterpretationClozapine, unlike the other antipsychotics examined, causes marked gastrointestinal hypomotility, as previously hypothesized. Pre-emptive laxative treatment is recommended when starting clozapine.

Our findings show that while the students in both groups did not significantly differ in baseline empathy scores, the intervention group reported significantly higher empathy scores post-intervention. The intervention group also received significantly higher tutor ratings for their motivational interviewing (BECCI score) and overall OSCE performances. In conclusion, the teaching innovation "How to act-in-role" was effective not only in increasing medical students' self-reported empathy but also their competence in consultation skills.

A significant decline in medical students' empathy scores was observed from year 5 to year 6, consistent with international findings. Peer assessments and tutor ratings of competence in MI/BI skills performance were moderately correlated, but peer assessments were negatively correlated with medical students' self-rated empathy. Senior medical students who self-rated as more empathic received lower competence evaluations of MI/BI skills from their peers. Interventions to further investigate teaching and learning of empathy are discussed.

BackgroundObesity is a significant problem for people with serious mental illness. We aimed to consider body size from the perspective of long-stay psychiatric inpatients, focussing on: weight gain and its causes and impacts; diet and physical activity; and the perceived ability to make meaningful change in these domains.MethodA mixed methods study with 51 long-term psychiatric forensic and rehabilitation inpatients using semi-structured interviews combined with biometric and demographic data.Results94% of participants were overweight or obese (mean BMI 35.3, SD 8.1). They were concerned about their weight, with 75% of them attempting to lose weight. Qualitative responses indicated low personal effectiveness and self-stigmatisation. Participants viewed their weight gain as something ‘done to them’ through medication, hospitalisation and leave restrictions. A prevailing theme was that institutional constraints made it difficult to live a healthy life (just the way the system is). Many had an external locus of control, viewing weight loss as desirable but unachievable, inhibited by environmental factors and requiring a quantum of motivation they found hard to muster. Despite this, participants were thoughtful and interested, had sound ideas for weight loss, and wished to be engaged in a shared endeavour to achieve better health outcomes. Consulting people as experts on their experiences, preferences, and goals may help develop new solutions, remove unidentified barriers, and improve motivation.ConclusionsThe importance of an individualised, multifactorial approach in weight loss programmes for this group was clear. Patient-led ideas and co-design should be key principles in programme and environmental design.
