During the COVID-19 pandemic, telesimulation became particularly important to continue the education of medical students during disrupted clerkships while maintaining social distancing.

To describe our experiences of adapting to telesimulation and evaluate this from student and faculty perspectives.

The intervention was evaluated using anonymous surveys consisting of statements rated on a five-point Likert scale from strongly disagree to strongly agree and open-ended questions asking students and facilitators what went well, what they would change and why, and for any other comments.

Adaptations addressed the logistics of online delivery and the structure and content of scenarios. Logistical considerations included central organization of sessions to relieve pressures on clinicians. Pre-session case discussions were introduced to maximise time with simulated patients and give students space to socialise. Content was modified to ensure functionality online and reflect the context of the pandemic. A total of 278 students and 24 facilitators participated in the telesimulation sessions. 98.1% of students (N=109) rated the sessions as very good or good. Students benefited from practicing skills, especially clinical situations which they would rarely encounter as students, and receiving feedback. Facilitators (N=6) felt that students learnt both skills for online consultations and skills that can be transferred to face-to-face situations, but were ambivalent on whether students would benefit more from face-to-face sessions.

Telesimulation is a safe and effective option that offers additional opportunities for students to develop telemedicine skills. Going forward, telesimulation should complement face-to-face delivery to develop future clinicians who are proficient in both remote and face-to-face working.

Education leads for undergraduate psychiatry in UK medical schools completed questionnaires on adaptations made to undergraduate psychiatry education, their impact and what lessons could be learnt for the future.

Respondents from 24 medical schools across the UK reported a major shift to online teaching delivery, with reduced workplace learning and increased use of teleconferencing, online tasks and self-directed learning. Changes were implemented with some faculty training provided, but little additional funding or resources from medical schools or National Health Service trusts. A variety of challenges and opportunities were reported.

Despite the extraordinary efforts of education leads to maintain undergraduate psychiatry education, the pandemic may affect the development of students’ professional competencies and recruitment into psychiatry. Individual clinicians, trusts and medical and foundation schools have much to offer, and need to work with students to replace what has been lost during the pandemic.

Depression and obesity are highly prevalent, and major impacts on public health frequently co-occur. Recently, we reported that having depression moderates the effect of the FTO gene, suggesting its implication in the association between depression and obesity.

To confirm these findings by investigating the FTO polymorphism rs9939609 in new cohorts, and subsequently in a meta-analysis.

The sample consists of 6902 individuals with depression and 6799 controls from three replication cohorts and two original discovery cohorts. Linear regression models were performed to test for association between rs9939609 and body mass index (BMI), and for the interaction between rs9939609 and depression status for an effect on BMI. Fixed and random effects meta-analyses were performed using METASOFT.

In the replication cohorts, we observed a significant interaction between FTO, BMI and depression with fixed effects meta-analysis (β=0.12, P = 2.7 × 10−4) and with the Han/Eskin random effects method (P = 1.4 × 10−7) but not with traditional random effects (β = 0.1, P = 0.35). When combined with the discovery cohorts, random effects meta-analysis also supports the interaction (β = 0.12, P = 0.027) being highly significant based on the Han/Eskin model (P = 6.9 × 10−8). On average, carriers of the risk allele who have depression have a 2.2% higher BMI for each risk allele, over and above the main effect of FTO.

This meta-analysis provides additional support for a significant interaction between FTO, depression and BMI, indicating that depression increases the effect of FTO on BMI. The findings provide a useful starting point in understanding the biological mechanism involved in the association between obesity and depression.

We used an online questionnaire to investigate medical students' perceptions of the apparent hierarchy between specialties, whether they have witnessed disparaging comments (‘badmouthing’ or ‘bashing’) against other specialists and whether this has had an effect on their career choice.

In total, 960 students from 13 medical schools completed the questionnaire; they ranked medical specialties according to the level of badmouthing and answered questions on their experience of specialty bashing. Psychiatry and general practice attracted the greatest number of negative comments, which were made by academic staff, doctors and students. Twenty-seven per cent of students had changed their career choice as a direct result of bashing and a further 25.5% stated they were more likely to change their specialty choice. Although 80.5% of students condemned badmouthing as unprofessional, 71.5% believed that it is a routine part of practising medicine.

Bashing of psychiatry represents another form of stigmatisation that needs to be challenged in medical schools. It not only has an impact on recruitment into the specialty, but also has the wider effect of stigmatising people with mental health disorders.

Major depressive disorder (MDD) is a common and disabling condition with well-established heritability and environmental risk factors. Gene–environment interaction studies in MDD have typically investigated candidate genes, though the disorder is known to be highly polygenic. This study aims to test for interaction between polygenic risk and stressful life events (SLEs) or childhood trauma (CT) in the aetiology of MDD.

The RADIANT UK sample consists of 1605 MDD cases and 1064 controls with SLE data, and a subset of 240 cases and 272 controls with CT data. Polygenic risk scores (PRS) were constructed using results from a mega-analysis on MDD by the Psychiatric Genomics Consortium. PRS and environmental factors were tested for association with case/control status and for interaction between them.

PRS significantly predicted depression, explaining 1.1% of variance in phenotype (p = 1.9 × 10−6). SLEs and CT were also associated with MDD status (p = 2.19 × 10−4 and p = 5.12 × 10−20, respectively). No interactions were found between PRS and SLEs. Significant PRSxCT interactions were found (p = 0.002), but showed an inverse association with MDD status, as cases who experienced more severe CT tended to have a lower PRS than other cases or controls. This relationship between PRS and CT was not observed in independent replication samples.

CT is a strong risk factor for MDD but may have greater effect in individuals with lower genetic liability for the disorder. Including environmental risk along with genetics is important in studying the aetiology of MDD and PRS provide a useful approach to investigating gene–environment interactions in complex traits.

Strategies to dissect phenotypic and genetic heterogeneity of major depressive disorder (MDD) have mainly relied on subphenotypes, such as age at onset (AAO) and recurrence/episodicity. Yet, evidence on whether these subphenotypes are familial or heritable is scarce. The aims of this study are to investigate the familiality of AAO and episode frequency in MDD and to assess the proportion of their variance explained by common single nucleotide polymorphisms (SNP heritability).

For investigating familiality, we used 691 families with 2–5 full siblings with recurrent MDD from the DeNt study. We fitted (square root) AAO and episode count in a linear and a negative binomial mixed model, respectively, with family as random effect and adjusting for sex, age and center. The strength of familiality was assessed with intraclass correlation coefficients (ICC). For estimating SNP heritabilities, we used 3468 unrelated MDD cases from the RADIANT and GSK Munich studies. After similarly adjusting for covariates, derived residuals were used with the GREML method in GCTA (genome-wide complex trait analysis) software.

Significant familial clustering was found for both AAO (ICC = 0.28) and episodicity (ICC = 0.07). We calculated from respective ICC estimates the maximal additive heritability of AAO (0.56) and episodicity (0.15). SNP heritability of AAO was 0.17 (p = 0.04); analysis was underpowered for calculating SNP heritability of episodicity.

AAO and episodicity aggregate in families to a moderate and small degree, respectively. AAO is under stronger additive genetic control than episodicity. Larger samples are needed to calculate the SNP heritability of episodicity. The described statistical framework could be useful in future analyses.

Obesity has been shown to be associated with depression and it has been suggested that higher body mass index (BMI) increases the risk of depression and other common mental disorders. However, the causal relationship remains unclear and Mendelian randomisation, a form of instrumental variable analysis, has recently been employed to attempt to resolve this issue.

To investigate whether higher BMI increases the risk of major depression.

Two instrumental variable analyses were conducted to test the causal relationship between obesity and major depression in RADIANT, a large case–control study of major depression. We used a single nucleotide polymorphism (SNP) in FTO and a genetic risk score (GRS) based on 32 SNPs with well-established associations with BMI.

Linear regression analysis, as expected, showed that individuals carrying more risk alleles of FTO or having higher score of GRS had a higher BMI. Probit regression suggested that higher BMI is associated with increased risk of major depression. However, our two instrumental variable analyses did not support a causal relationship between higher BMI and major depression (FTO genotype: coefficient −0.03, 95% CI −0.18 to 0.13, P = 0.73; GRS: coefficient −0.02, 95% CI −0.11 to 0.07, P = 0.62).

Our instrumental variable analyses did not support a causal relationship between higher BMI and major depression. The positive associations of higher BMI with major depression in probit regression analyses might be explained by reverse causality and/or residual confounding.

Although usually thought of as external environmental stressors, a significant heritable component has been reported for measures of stressful life events (SLEs) in twin studies.

We examined the variance in SLEs captured by common genetic variants from a genome-wide association study (GWAS) of 2578 individuals. Genome-wide complex trait analysis (GCTA) was used to estimate the phenotypic variance tagged by single nucleotide polymorphisms (SNPs). We also performed a GWAS on the number of SLEs, and looked at correlations between siblings.

A significant proportion of variance in SLEs was captured by SNPs (30%, p = 0.04). When events were divided into those considered to be dependent or independent, an equal amount of variance was explained for both. This ‘heritability’ was in part confounded by personality measures of neuroticism and psychoticism. A GWAS for the total number of SLEs revealed one SNP that reached genome-wide significance (p = 4 × 10−8), although this association was not replicated in separate samples. Using available sibling data for 744 individuals, we also found a significant positive correlation of R2 = 0.08 in SLEs (p = 0.03).

These results provide independent validation from molecular data for the heritability of reporting environmental measures, and show that this heritability is in part due to both common variants and the confounding effect of personality.

Little is known about the impact of different types of stressful events (for example divorce v. bereavement) on unipolar depression compared with bipolar disorder. Inconsistencies exist concerning the association between independent events (beyond an individual's control, such as bereavement) and bipolar disorder.

To examine the role of specific, independent and dependent events in mood disorders.

Life-event information was collected from 512 people with bipolar disorder, 1448 people with unipolar depression and over 600 controls.

Various events were associated with unipolar depression and bipolar disorder, but some event specificity was detected. For example, financial crisis was more strongly related to bipolar disorder rather than unipolar depression. Independent events were only related to unipolar depression and not bipolar disorder.

The events that were linked to bipolar disorder and unipolar depression were similar. Independent events were not associated with bipolar episodes, suggesting that life stress may be a consequence of, rather than a trigger for, bipolar episodes.

An online survey was used to examine the attitudes of clinical, academic and trainee psychiatrists on the delivery of undergraduate education and why students are not choosing psychiatry as a career. This paper explores whether attitudes to teaching psychiatry to medical students is a factor in poor recruitment to the specialty.

Overall, 390 psychiatrists completed the survey. All groups were highly committed to psychiatry education, but there were significant differences in attitudes that may have an impact on the delivery of medical student teaching, which in turn may influence recruitment. Five major themes emerged from the survey, the most dominant being stigmatisation of psychiatric patients and professionals by the medical profession. These divergent attitudes to teaching and stigma may be contributing to low levels of recruitment into psychiatry.

Education of the next generation of psychiatrists is a high priority and active measures are needed to increase commitment and enthusiasm in undergraduate education.

Studies exploring gene–environment interplay in affective disorders now include very large numbers of participants. Methods for evaluating the role of adversity in such studies need to be developed that do not rely on lengthy and labour-intensive interviews. In the present study, a brief questionnaire method for measuring 11 adverse events reported before interview and before their worst illness episodes by bipolar, unipolar and healthy control participants, participating in genetic association studies, was evaluated.

Five hundred and twelve bipolar disorder (BD) participants, 1447 participants with recurrent unipolar depression (UPD) and 1346 psychiatrically healthy control participants underwent the researcher-administered version of the List of Threatening Experiences Questionnaire (LTE-Q) for the 6 months before their worst affective episodes for UPD and BD participants, and for the 6 months before interview for the UPD participants and controls.

UPD and BD cases were significantly more likely to report at least one event, as well as more events in the 6 months before interview and before their worst illness episodes, than healthy controls. Both manic and depressive episodes were significantly associated with adverse events in the BD cases. Depressed mood at the time of interview influenced event reporting in UPD and control participants but not the BD cases. Age was negatively correlated with the number of events reported by controls.

The researcher-administered LTE-Q provides a measure of case-control differences for adversity that is applicable in large genetic association studies. Confounding factors for event reporting include present mood and age.

An association between depression and headache is well established, but the specificity to migraine is unclear.

To investigate the specificity of the association of depression and migraine.

People with recurrent depression (n=1259) were compared with psychiatrically healthy controls (n=851) to investigate headache defined according to International Headache Society criteria in each group.

All headache types were more prevalent in the case group than in the controls. However, the strongest association was between depression and migraine with aura (OR=5.6). Among participants with recurrent headaches, migraine with aura (but not other forms of headache) was highly significantly associated with depression.

The data suggest that not only is there a general relationship between headache and depression but also that among people with recurrent headache there is a specific association between depression and migraine with aura. The association is likely to be explained by overlapping aetiological risk factors.

Few studies have examined the rates of physical disorders in those with recurrent depression.

To examine self-reported physical disorders in people with recurrent depression compared with a psychiatrically healthy control group.

As part of a genetic case-control association study, 1546 participants with recurrent depression and 884 controls were interviewed about lifetime ever treatment for 16 different physical health disorders.

The cases group had a significantly higher frequency of 14 physical disorders and more obesity than the control group. After controlling for age, gender, body mass index (BMI) and multiple testing, those in the cases group had significantly higher rates of gastric ulcer, rhinitis/hay fever, osteoarthritis, thyroid disease, hypertension and asthma.

People with recurrent depression show high rates of many common physical disorders. Although this can be partly explained by BMI, shared aetiological pathways such as dysfunction of the hypothalamic–pituitary axis may have a role.
