Background Patient and public involvement (PPI) is an increasing priority in health‐related research and education. Attracting and supporting people from different demographic groups to give up their time and get involved is important to help ensure that all parts of society are empowered, represented and their voices heard in decisions that may affect their health and quality of life. Objectives (1) To determine if a demographically diverse cross‐section of society would be interested in contributing to healthcare research and education. (2) To understand factors that can act as barriers and enablers to effective and diverse PPI. Method PPI survey data was collected via engagement events, with the aim of scoping interest in PPI from a diverse public. A Focus Group study involving members of the public, academic and professional service staff, was then conducted to gain a deeper understanding around the barriers and enablers of diversity within PPI. Results 71% of a diverse rich public indicated they would like to get involved in healthcare research and teaching. 76% of survey respondents indicated that they would be happy to share a personal or family experience of healthcare. The two biggest factors impacting on our cohort getting involved are’ availability of time’ and ‘being aware of PPI opportunities’. These factors may disproportionally affect specific groups. Shared and individual PPI enablers and barriers were identified across all stakeholder groups within the Focus Group Study, as well as generic and novel factors that would impact on an institutions’ ability to improve PPI diversity. Conclusion These data points confirm a demographically diverse public's appetite to get involved in academic health research and teaching. This needs to be recognised and harnessed to ensure public contributor networks are representative of society. Equality Impact Assessments should be undertaken in relation to all PPI opportunities. There is a need to recognise the investment of time and resources required to build mutually beneficial relationships with diverse communities as well as the development of inclusive ‘fit for purpose’ PPI infrastructures to support the uptake of diverse PPI contributors. Public Contribution This study involved members of the public responding to a short survey. Public contributors made up one of the three focus groups. The School of Medicine lead public contributor was also involved in the preparation of this manuscript.

Sleep loss may trigger mood episodes in people with bipolar disorder but individual differences could influence vulnerability to this trigger. To determine whether bipolar subtype (bipolar disorder type I (BP-I) or II (BD-II)) and gender were associated with vulnerability to the sleep loss trigger. During a semi-structured interview, 3140 individuals (68% women) with bipolar disorder (66% BD-I) reported whether sleep loss had triggered episodes of high or low mood. DSM-IV diagnosis of bipolar subtype was derived from case notes and interview data. Sleep loss triggering episodes of high mood was associated with female gender (odds ratio (OR) = 1.43, 95% CI 1.17-1.75, < 0.001) and BD-I subtype (OR = 2.81, 95% CI 2.26-3.50, < 0.001). Analyses on sleep loss triggering low mood were not significant following adjustment for confounders. Gender and bipolar subtype may increase vulnerability to high mood following sleep deprivation. This should be considered in situations where patients encounter sleep disruption, such as shift work and international travel.

Individuals with a mental health disorder appear to be at increased risk of medical illness. To examine rates of medical illnesses in patients with bipolar disorder (n = 1720) and to examine the clinical course of the bipolar illness according to lifetime medical illness burden. Participants recruited within the UK were asked about the lifetime occurrence of 20 medical illnesses, interviewed using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) and diagnosed according to DSM-IV criteria. We found significantly increased rates of several medical illnesses in our bipolar sample. A high medical illness burden was associated with a history of anxiety disorder, rapid cycling mood episodes, suicide attempts and mood episodes with a typically acute onset. Bipolar disorder is associated with high rates of medical illness. This comorbidity needs to be taken into account by services in order to improve outcomes for patients with bipolar disorder and also in research investigating the aetiology of affective disorder where shared biological pathways may play a role.

IntroductionUniversity life represents a critical period for young adults, providing opportunities for personal growth and development of coping skills but also posing significant mental health challenges. Recent trends indicate rising mental health concerns among university students, exacerbated by the COVID-19 pandemic and its aftermath. This study aims to address gaps in longitudinal data on student mental health in the UK and to identify risk and protective factors across diverse student populations.Methods and analysisThe current Nurture-U survey is developed from the U-Flourish biannual survey study piloted at Queen’s and Oxford universities in Canada and the UK, respectively. Nurture-U is a longitudinal survey study conducted at five UK universities, aiming to create a comprehensive data set from over 5000 students. The study will collect data at the start and completion of each academic year, using validated measures to assess well-being, mental health symptoms, lifestyle factors and access to support. Recruitment will target all students, with an emphasis on first-year students, to track their mental health trajectory from university entry through subsequent years.Ethics and disseminationEthical approval has been obtained from relevant committees at each participating university. Students will provide informed consent prior to participation, with risk messages and support information provided for those indicating self-harm or suicidal thoughts. Data will be de-identified and securely stored, with results disseminated through academic publications, social media and student engagement activities.

The enormous public health importance of mood disorders, when considered alongside their substantial heritabilities, has stimulated much work, predominantly in bipolar disorder but increasingly in unipolar depression, aimed at identifying susceptibility genes using both positional and functional molecular genetic approaches. Several regions of interest have emerged in linkage studies and, recently, evidence implicating specific genes has been reported; the best supported include BDNF and DAOA but further replications are required and phenotypic relationships and biological mechanisms need investigation. The complexity of psychiatric phenotypes is demonstrated by (a) the evidence accumulating for an overlap in genetic susceptibility across the traditional classification systems that divide disorders into schizophrenia and mood disorders, and (b) evidence suggestive of gene-environment interactions.

There has been increasing interest in the association between childhood trauma and psychosis. Proposals for potential mechanisms involved include affective dysregulation and cognitive appraisals of threat. To establish if, within bipolar disorder, childhood events show a significant association with psychosis, and in particular with symptoms driven by dysregulation of mood or with a persecutory content. Data on lifetime-ever presence of psychotic symptoms were determined by detailed structured interview with case-note review (n = 2019). Childhood events were recorded using a self-report questionnaire and case-note information. There was no relationship between childhood events, or childhood abuse, and psychosis per se. Childhood events were not associated with an increased risk of persecutory or other delusions. Significant associations were found between childhood abuse and auditory hallucinations, strongest between sexual abuse and mood congruent or abusive voices. These relationships remain significant even after controlling for lifetime-ever cannabis misuse. Within affective disorder, the relationship between childhood events and psychosis appears to be relatively symptom-specific. It is possible that the pathways leading to psychotic symptoms differ, with delusions and non-hallucinatory symptoms being influenced less by childhood or early environmental experience.

Pregnancy and childbirth are a period of high risk for women with bipolar disorder and involve difficult decisions particularly about continuing or stopping medications.AimsTo explore what clinical predictors may help to individualise the risk of perinatal recurrence in women with bipolar disorder. Information was gathered retrospectively by semi-structured interview, questionnaires and case-note review from 887 women with bipolar disorder who have had children. Clinical predictors were selected using backwards stepwise logistic regression, conditional permutation random forests and reinforcement learning trees. Previous perinatal history of affective psychosis or depression was the most significant predictor of a perinatal recurrence (odds ratio (OR) = 8.5, 95% CI 5.04-14.82 and OR = 3.6, 95% CI 2.55-5.07 respectively) but even parous women with bipolar disorder without a previous perinatal mood episode were at risk following a subsequent pregnancy, with 7% developing postpartum psychosis. Previous perinatal history of affective psychosis or depression is the most important predictor of perinatal recurrence in women with bipolar disorder and can be used to individualise risk assessments.Declaration of interestNone.

The Schizophrenia Psychiatric Genome-Wide Association Study Consortium (PGC) highlighted 81 single-nucleotide polymorphisms (SNPs) with moderate evidence for association to schizophrenia. After follow-up in independent samples, seven loci attained genome-wide significance (GWS), but multi-locus tests suggested some SNPs that did not do so represented true associations. We tested 78 of the 81 SNPs in 2640 individuals with a clinical diagnosis of schizophrenia attending a clozapine clinic (CLOZUK), 2504 cases with a research diagnosis of bipolar disorder, and 2878 controls. In CLOZUK, we obtained significant replication to the PGC-associated allele for no fewer than 37 (47%) of the SNPs, including many prior GWS major histocompatibility complex (MHC) SNPs as well as 3/6 non-MHC SNPs for which we had data that were reported as GWS by the PGC. After combining the new schizophrenia data with those of the PGC, variants at three loci ( ITIH3/4 , CACNA1C and SDCCAG8 ) that had not previously been GWS in schizophrenia attained that level of support. In bipolar disorder, we also obtained significant evidence for association for 21% of the alleles that had been associated with schizophrenia in the PGC. Our study independently confirms association to three loci previously reported to be GWS in schizophrenia, and identifies the first GWS evidence in schizophrenia for a further three loci. Given the number of independent replications and the power of our sample, we estimate 98% (confidence interval (CI) 78–100%) of the original set of 78 SNPs represent true associations. We also provide strong evidence for overlap in genetic risk between schizophrenia and bipolar disorder.

North American studies show bipolar disorder is associated with elevated rates of problem gambling; however, little is known about rates in the different presentations of bipolar illness. To determine the prevalence and distribution of problem gambling in people with bipolar disorder in the UK. The Problem Gambling Severity Index was used to measure gambling problems in 635 participants with bipolar disorder. Moderate to severe gambling problems were four times higher in people with bipolar disorder than in the general population, and were associated with type 2 disorder (OR = 1.74, P = 0.036), history of suicidal ideation or attempt (OR = 3.44, P = 0.02) and rapid cycling (OR = 2.63, P = 0.008). Approximately 1 in 10 patients with bipolar disorder may be at moderate to severe risk of problem gambling, possibly associated with suicidal behaviour and a rapid cycling course. Elevated rates of gambling problems in type 2 disorder highlight the probable significance of modest but unstable mood disturbance in the development and maintenance of such problems.
