RESUMO
INTRODUCTION: According to the 11th Revision of the International Classification of Diseases, burnout is defined as a syndrome resulting from chronic work-related stress that has not been successfully managed. Burnout is increasingly prevalent amongst medical students and has been shown to lead to worsened academic engagement, feelings of inadequacy, poor mental health and increased risk of withdrawal from the course. The aim of this study was to explore the experience of burnout amongst early year medical students and evaluate the perceived impact of a reflection-based intervention on their awareness and experience of burnout. METHODS: The reflection-based intervention comprised two tutorials covering the presentation, drivers, impact and management strategies for burnout syndrome. These were introduced into the second-year medical curriculum at Imperial College London. As part of the reflection-based intervention, students were invited to complete an anonymous Qualtrics form three times during the academic year. This included the Shirom-Melamed Burnout Measure (SMBM) and a free-text question prompting the student to consider their stressors at the time of completing the intervention. The former is composed of 14-questions measuring the extent of feelings or behaviours suggestive of burnout, divided into three categories: physical fatigue, cognitive weariness and emotional exhaustion. At the end of the academic year, students were invited to participate in an online focus group to further explore their experience of burnout and their perceived value of the reflection-based intervention. Results of the SMBM were explored descriptively; free-text questions and the focus group transcript were analysed using inductive thematic analysis. RESULTS: A total of 59 submissions for the reflection-based intervention were analysed: 26 students participated and consented in the first round, 8 in the second and 25 in the third round. Overall median burnout scores were 4 (IQR 3-5), 2 (IQR 1-4) and 3 (IQR 2-5) in each round of the SMBM, respectively. A total of 8 (30.8%) met the threshold for severe burnout (≥ 4.4) in round 1 of the questionnaire, zero in the second round and 4 (16%) in the third round. Physical and cognitive fatigue showed higher median scores than emotional exhaustion in every round. Four students participated in the focus group, which had two sections. The first was reflecting on burnout in medical school and the intervention, which revealed four themes: (1) indicators of burnout (often insidious, but may involve lack of energy and motivation, or changes in perceived personality); (2) perceived drivers of burnout (perceived expectation that medical school is supposed to be challenging and consistent prioritisation of work over wellbeing); (3) working habits of medical students (unachievable self-expectations and feelings of guilt when not working); (4) value of the intervention (the teaching and reflection-based intervention prompted students to identify signs of burnout in themselves and consider management strategies). The second section included considerations for implementing burnout interventions into the medical school curriculum, which revealed three themes: (1) desire to learn about burnout (students hoped to gain insight into burnout and methods of prevention as part of their curriculum); (2) importance of community (group interventions and the involvement of Faculty helped students feel less isolated in their experiences); (3) feasibility of interventions (sustainable interventions are likely to be those that are efficient, such as using multiple-choice questions, and with allocated periods in their timetable). CONCLUSION: Second-year medical students demonstrated symptoms and signs of burnout, including exhaustion, lack of motivation and changes in personality. They also expressed a desire to gain greater awareness of burnout and insight into preventative strategies within the medical curriculum. Whilst certain drivers of burnout can be prevented by students themselves through adequate prevention strategies, many remain systemic issues which require curriculum-level change to be effectively addressed. The students found that the reflection-based intervention was effective at improving their perception of burnout and a convenient tool to use, which could be implemented more widely and continued longer-term throughout medical school.

BACKGROUND: In 2019 a new Lifestyle Medicine (LM) module was introduced to the undergraduate medical curriculum at Imperial College London. Lifestyle Medicine is an emergent discipline which aims to tackle the increasing burden of non-communicable disease. Previous work has suggested that students value clinical teaching over traditional Public Health topics. Taking a constructivist view of learning, this paper assesses changes in medical students' attitudes towards Public Health and LM in response to living through a pandemic. We then make suggestions as to how this lived experience might be useful in teaching LM, and discuss the interaction between teaching, behaviour, and experience with consideration of self-determination theories in learning. METHODS: First-year medical students were surveyed at the end of their first year of teaching and asked if living during the COVID-19 pandemic had changed the value they place on LM and if so, how. Thematic analysis was conducted on responses representing 71% (n = 216) of the year group. RESULTS: Four themes were defined in the data: acknowledging importance; impact on behaviour; health inequalities and the wider determinants; and promoting Public Health and prevention. These themes highlight the distinct levels through which the pandemic has had an impact: from personal behaviour to population health. CONCLUSIONS: This is the first study to look at the impact of living through a pandemic on attitudes to LM. Our results suggest that the pandemic has led to increased reflection on health behaviours. The lived-experience of COVID-19 may facilitate a better understanding of health inequalities and their impact, alongside the opportunities presented by effective LM interventions.

BACKGROUND: Sleep disturbances are associated with worse cognitive and psychotic symptoms in individuals with schizophrenia. Growing literature reveals sleep spindle deficits in schizophrenia may be an endophenotype reflecting a dysfunctional thalamo-thalamic reticular nucleus-cortical circuit. Since thalamic functions link to cognitive, positive and negative symptoms, it is possible that sleep spindle activity is associated with these symptoms. The primary objectives of this systematic review were to assess the associations of sleep spindle activity in psychotic patients with 1) cognitive functions; and 2) positive and negative symptom severity. A secondary objective was to examine which spindle parameter would be the most consistent parameter correlating with cognitive functions, and positive and negative symptoms. METHOD: Observational studies reporting an association between sleep spindle activity and cognitive functions, positive and negative symptoms in patients with psychotic disorders were considered eligible. We developed a comprehensive electronic search strategy to identify peer-reviewed studies in Pubmed, Embase, PsycINFO and CINAHL covering all dates up to the search date in May 2020 with no language restriction. The references of published articles were hand-searched for additional materials. The authors of published articles were contacted for newer or unpublished data. Risk of bias was assessed by Appraisal of Cross-sectional Studies (AXIS). RESULTS: A total 11 cross-sectional studies (n = 255) with low-to-moderate quality, were selected for the systematic review. 8 of them addressed the association between sleep spindle activity and cognitive functions (n = 193), of which 6 studies reported positive correlations (r only reported in 4 studies, from 0.45 to 0.75). Out of multiple cognitive domains, we have only found attention/cognitive processing speed to have a more consistent positive association with sleep spindle activity. On the other hand, 8 studies investigated the relationship between sleep spindle and positive/negative symptom severity (n = 190), but findings were inconsistent. Spindle density is the most consistent parameter correlating with cognitive functions, while the best spindle parameter for correlating with positive and negative symptom severity cannot be identified due to mixed results. DISCUSSION: This systematic review confirms the linkage between sleep spindle activity and cognitive functions. However, included studies had small sample sizes, with high risks of sampling and response bias. Moreover, confounders were often not controlled. The heterogeneous report of spindle parameters and use of cognitive assessment tools rendered meta-analysis infeasible. It is necessary to examine the longitudinal change of sleep spindle activity with the course of illness, as well as the effect of sleep spindle enhancing agents on cognitive function.
RESUMO
OBJECTIVE: To evaluate the impact of a school-based sleep education programme on adolescent sleep and sleep knowledge. METHODS: This is the first outcome report on 'Teensleep': a novel, teacher-led programme, comprising ten lessons that can be delivered flexibly. Students in Year 10 (n = 1504; mean age = 14.14 ± 0.35 years) from ten UK state (non-fee-paying) secondary schools received the lessons and parents received a leaflet. Effectiveness was assessed using measures across two time points (pre- and post-intervention). Students completed questionnaires on sleep knowledge, sleep quality, sleep behaviour, sleep hygiene, daytime sleepiness and health-related quality of life. A sub-sample provided objective (actigraphy, n = 84) and subjective (sleep diary, n = 74) sleep measures. RESULTS: Large improvements in sleep knowledge (d = 0.78), and smaller improvements in sleep quality (d = 0.15) and sleep hygiene (d = 0.11) were observed, but not in daytime sleepiness or health-related quality of life. Small and limited changes in subjective and objective sleep patterns were found. Baseline sleep quality was differentially associated with key outcomes, with those initially self-reporting poor sleep demonstrating an improvement in sleep quality, sleep hygiene and sleepiness. CONCLUSION: Teensleep was effective at improving sleep knowledge but sleep changes were small. Such interventions have traditionally focused on gains for all students, but this study suggests that poor sleepers may be the most likely to experience immediate direct sleep benefits. Follow-up studies are required to investigate whether or not sleep education provides long-term benefits as a step towards preventative sleep medicine.
RESUMO
Based on the emerging interest in the effects of gut microbiota on cognition, this proof-of-concept study assessed how children aged 7 to 9 with low reading scores responded to the ingestion of a 3-month prebiotic supplement versus a placebo. As a secondary aim, the effects of the prebiotic on cognition, sleep, behaviour, mood, anxiety, and cortisol were assessed. In this sample, the prebiotic did not affect any of the outcome measures.

Depression in adolescence is frequently characterised by symptoms of irritability. Fluoxetine is the antidepressant with the most favourable benefit:risk ratio profile to treat adolescent depression, but the neural mechanisms underlying antidepressant drugs in the young brain are still poorly understood. Previous studies have characterised the neural effects of long-term fluoxetine treatment in depressed adolescents, but these are limited by concurrent mood changes and a lack of placebo control. There is also recent evidence suggesting that fluoxetine reduces the processing of anger in young healthy volunteers, which is consistent with its effect for the treatment of irritability in this age group, but this remains to be investigated in depressed adolescents. Here we assessed the effects of a single, first dose of 10 mg fluoxetine vs. placebo on neural response to anger cues using fMRI in a sample of adolescents with Major Depressive Disorder (MDD) who had been recently prescribed fluoxetine. As predicted, adolescents receiving fluoxetine showed reduced activity in response to angry facial expressions in the amygdala-hippocampal region relative to placebo. Activity in the dorsal anterior cingulate cortex (dACC) was also increased. No changes in symptoms were observed. These results demonstrate, for the first time in depressed adolescents, that fluoxetine has immediate neural effects on core components of the cortico-limbic circuitry prior to clinical changes in mood. The effect on anger is consistent with our previous work and could represent a key mechanism through which fluoxetine may act to alleviate irritability symptoms in adolescent depression.

OBJECTIVE: Later school start times for adolescents have been implemented in the US and associated benefits found, although no randomised controlled trials (RCT) have been undertaken. The objective of this study was to evaluate the impact of two school interventions in the UK, a delayed start time and a sleep education programme, on students' academic performance, sleep outcomes and health-related quality of life. METHODS: The study had an RCT design to enable an investigation into the differential effects of two interventions or a combination of both: schools were to delay their start time to 10:00am and/or provide a classroom-based sleep education programme. The recruitment target was 100 state (non-fee-paying) secondary schools. Participants were to be students in Year 10/11 (14-16-year-olds). RESULTS: Despite much media coverage, only two schools volunteered to take part in the RCT. The main challenges faced in recruitment fell under three categories: research design, school, and project-specific issues. The delayed start time and prospect of randomisation to this intervention were the overwhelming reasons cited for not taking part. Facilitators and barriers to research were identified. Recommendations include carrying out a feasibility study prior to a main trial, allowing adequate time for recruitment, involving stakeholders throughout the decision-making process, incorporating independent (fee-paying) schools in recruitment, focusing on students not taking important examinations or involving an older year group with greater independence. CONCLUSION: The Teensleep study provides supporting evidence that evaluating the effects of a change in school start times through an RCT is unfeasible in the UK.

Insomnia is a common health complaint world-wide. Insomnia is a risk factor in the development of other psychological and physiological disorders. Therefore understanding the mechanisms which predispose an individual to developing insomnia has great transdiagnostic value. However, whilst it is largely accepted that a vulnerable phenotype exists there is a lack of research which aims to systematically assess the make-up of this phenotype. This review outlines the research to-date, considering familial aggregation and the genetics and psychology of stress-reactivity. A model will be presented in which negative affect (neuroticism) and genetics (5HTTLPR) are argued to lead to disrupted sleep via an increase in stress-reactivity, and further that the interaction of these variables leads to an increase in learned negative associations, which further increase the likelihood of poor sleep and the development of insomnia.

OBJECTIVES: This secondary analysis of data from a randomised controlled trial explores associations between common symptom clusters and evaluates pre-treatment to post-treatment changes in clinical levels of these symptoms following cognitive behaviour therapy for insomnia (CBT-I). METHODS: Baseline data from 113 participants with insomnia were explored to establish rates of and associations between clinical levels of fatigue, anxiety and depression across the sample. Effects of CBT-I on this symptom cluster were also explored by examining changes in pre-treatment to post-treatment levels of fatigue, anxiety and depression. RESULTS: At baseline, the most common symptom presentation was insomnia + fatigue, and 30% of the sample reported at least three co-morbid symptoms. Post-CBT, the number of those experiencing clinical insomnia and clinical fatigue decreased. There were no changes in anxiety rates from baseline to post-treatment in the CBT group and modest reductions in rates of those with clinical depression. Seven individuals (9.6%) from the CBT group were completely symptom free at post-treatment compared with 0% from the treatment as usual condition. Chi-square analysis revealed a significant relationship between group allocation and changes in symptoms of insomnia and fatigue. No such relationship was found between group allocation and mood variables. CONCLUSIONS: These findings confirm the high rate of symptom co-morbidities among cancer patients and highlight strong associations between sleep and fatigue. CBT-I appears to offer generalised benefit to the symptom cluster as a whole and, specifically, is effective in reducing fatigue, which exceeded clinical cut-offs prior to implementation of the intervention. This has implications for the diagnosis/management of common symptoms in cancer patients.
