The mental health and well-being profile of young adults using social media

The relationship between mental health and social media has received significant research and policy attention. However, there is little population-representative data about who social media users are which limits understanding of confounding factors between mental health and social media. Here we profile users of Facebook, Twitter, Instagram, Snapchat and YouTube from the Avon Longitudinal Study of Parents and Children population cohort (N = 4083). We provide estimates of demographics and mental health and well-being outcomes by platform. We find that users of different platforms and frequencies are not homogeneous. User groups differ primarily by sex and YouTube users are the most likely to have poorer mental health outcomes. Instagram and Snapchat users tend to have higher well-being than the other social media sites considered. Relationships between use-frequency and well-being differ depending on the specific well-being construct measured. The reproducibility of future research may be improved by stratifying by sex and being specific about the well-being constructs used

The effects of interoperable information technology networks on patient safety: a realist synthesis

Background Interoperable networks connect information technology systems of different organisations, allowing professionals in one organisation to access patient data held in another one. Health policy-makers in many countries believe that they will improve the co-ordination of services and, hence, the quality of services and patient safety. To the best of our knowledge, there have not been any previous systematic reviews of the effects of these networks on patient safety. Objectives The aim of the study was to establish how, why and in what circumstances interoperable information technology networks improved patient safety, failed to do so or increased safety risks. The objectives of the study were to (1) identify programme theories and prioritise theories to review; (2) search systematically for evidence to test the theories; (3) undertake quality appraisal, and use included texts to support, refine or reject programme theories; (4) synthesise the findings; and (5) disseminate the findings to a range of audiences. Design Realist synthesis, including consultation with stakeholders in nominal groups and semistructured interviews. Settings and participants Following a stakeholder prioritisation process, several domains were reviewed: older people living at home requiring co-ordinated care, at-risk children living at home and medicines reconciliation services for any patients living at home. The effects of networks on services in health economies were also investigated. Intervention An interoperable network that linked at least two organisations, including a maximum of one hospital, in a city or region. Outcomes Increase, reduction or no change in patients’ risks, such as a change in the risk of taking an inappropriate medication. Results We did not find any detailed accounts of the ways in which interoperable networks are intended to work and improve patient safety. Theory fragments were identified and used to develop programme and mid-range theories. There is good evidence that there are problems with the co-ordination of services in each of the domains studied. The implicit hypothesis about interoperable networks is that they help to solve co-ordination problems, but evidence across the domains showed that professionals found interoperable networks difficult to use. There is insufficient evidence about the effectiveness of interoperable networks to allow us to establish how and why they affect patient safety. Limitations The lack of evidence about patient-specific measures of effectiveness meant that we were not able to determine ‘what works’, nor any variations in what works, when interoperable networks are deployed and used by health and social care professionals. Conclusions There is a dearth of evidence about the effects of interoperable networks on patient safety. It is not clear if the networks are associated with safer treatment and care, have no effects or increase clinical risks. Future work Possible future research includes primary studies of the effectiveness of interoperable networks, of economies of scope and scale and, more generally, on the value of information infrastructures.

Views on social media and its linkage to longitudinal data from two generations of a UK cohort study

Background: Cohort studies gather huge volumes of information about a range of phenotypes but new sources of information such as social media data are yet to be integrated. Participant’s long-term engagement with cohort studies, as well as the potential for their social media data to be linked to other longitudinal data, could provide novel advances but may also give participants a unique perspective on the acceptability of this growing research area. Methods: Two focus groups explored participant views towards the acceptability and best practice for the collection of social media data for research purposes. Participants were drawn from the Avon Longitudinal Study of Parents and Children cohort; individuals from the index cohort of young people (N=9) and from the parent generation (N=5) took part in two separate 90-minute focus groups. The discussions were audio recorded and subjected to qualitative analysis. Results: Participants were generally supportive of the collection of social media data to facilitate health and social research. They felt that their trust in the cohort study would encourage them to do so. Concern was expressed about the collection of data from friends or connections who had not consented. In terms of best practice for collecting the data, participants generally preferred the use of anonymous data derived from social media to be shared with researchers. Conclusion: Cohort studies have trusting relationships with their participants; for this relationship to extend to linking their social media data with longitudinal information, procedural safeguards are needed. Participants understand the goals and potential of research integrating social media data into cohort studies, but further research is required on the acquisition of their friend’s data. The views gathered from participants provide important guidance for future work seeking to integrate social media in cohort studies

A low FODMAP diet is associated with changes in the microbiota and reduction in breath hydrogen but not colonic volume in healthy subjects

Background & aims Ingestion of poorly digested, fermentable carbohydrates (fermentable oligo-, di-, mono-saccharides and polyols; FODMAPs) have been implicated in exacerbating intestinal symptoms and the reduction of intake with symptom alleviation. Restricting FODMAP intake is believed to relieve colonic distension by reducing colonic fermentation but this has not been previously directly assessed. We performed a randomised controlled trial comparing the effect of a low FODMAP diet combined with either maltodextrin or oligofructose on colonic contents, metabolites and microbiota. Methods A parallel randomised controlled trial in healthy adults (n = 37). All subjects followed a low FODMAP diet for a week and supplemented their diet with either maltodextrin (MD) or oligofructose (OF) 7g twice daily. Fasted assessments performed pre- and post-diet included MRI to assess colonic volume, breath testing for hydrogen and methane, and stool collection for microbiota analysis. Results The low FODMAP diet was associated with a reduction in Bifidobacterium and breath hydrogen, which was reversed by oligofructose supplementation. The difference in breath hydrogen between groups post-intervention was 27ppm (95% CI 7 to 50, P Conclusion A low FODMAP diet reduces total bacterial count and gas production with little effect on colonic volume.Peer reviewe

Epicosm -a framework for linking online social media in epidemiological cohorts

Motivation Social media represent an unrivalled opportunity for epidemiological cohorts to collect large amounts of high-resolution time course data on mental health. Equally, the high-quality data held by epidemiological cohorts could greatly benefit social media research as a source of ground truth for validating digital phenotyping algorithms. However, there is currently a lack of software for doing this in a secure and acceptable manner. We worked with cohort leaders and participants to co-design an open-source, robust and expandable software framework for gathering social media data in epidemiological cohorts. Implementation Epicosm is implemented as a Python framework that is straightforward to deploy and run inside a cohort’s data safe haven. General features The software regularly gathers Tweets from a list of accounts and stores them in a database for linking to existing cohort data. Availability This open-source software is freely available at [https://dynamicgenetics.github.io/Epicosm/]

Bats in the Ghats: Agricultural intensification reduces functional diversity and increases trait filtering in a biodiversity hotspot in India

The responses of bats to land-use change have been extensively studied in temperate zones and the neotropics, but little is known from the palaeotropics. Effective conservation in heavily-populated palaeotropical hotspots requires a better understanding of which bats can and cannot survive in human-modified landscapes. We used catching and acoustic transects to examine bat assemblages in the Western Ghats of India, and identify the species most sensitive to agricultural change. We quantified functional diversity and trait filtering of assemblages in forest fragments, tea and coffee plantations, and along rivers in tea plantations with and without forested corridors, compared to protected forests. Functional diversity in forest fragments and shade-grown coffee was similar to that in protected forests, but was far lower in tea plantations. Trait filtering was also strongest in tea plantations. Forested river corridors in tea plantations mitigated much of the loss of functional diversity and the trait filtering seen on rivers in tea plantations without forested corridors. The bats most vulnerable to intensive agriculture were frugivorous, large, had short broad wings, or made constant frequency echolocation calls. The last three features are characteristic of forest animal-eating species that typically take large prey, often by gleaning. Ongoing conservation work to restore forest fragments and retain native trees in coffee plantations should be highly beneficial for bats in this landscape. The maintenance of a mosaic landscape with sufficient patches of forest, shade-grown coffee and riparian corridors will help to maintain landscape wide functional diversity in an area dominated by tea plantations

Community pharmacies mood intervention Study (CHEMIST) Feasibility and External Pilot randomised controlled trial protocol

Feasibility study: Objectives:Refine a bespoke enhanced support intervention (ESI) (including self-help materials, intervention manual and training) for implementation by community pharmacy (CP) staff to people with sub-threshold depression and long-term conditions (LTCs) based upon evidence-supported interventions in primary careDevelop and refine study procedures (recruitment strategies and set up, screening, participant recruitment, assessment, suitability of outcome measures and data collection procedures) for testing in the pilot study phaseDesign: A case series/qualitative studySetting: UK community pharmacyPopulation: Adults with long-term health conditions who screen-positive for depression but who do not reach the threshold for DSM IV Moderate Depressive disorderIntervention: Enhanced support intervention (ESI) delivered by an appropriately trained community pharmacy team member involving four to six sessions over four months. ESI is a modified form of an intervention within the collaborative care framework for sub-threshold depression validated in previous studies in UK primary care which appears suitable for implementation in community settings.Sample size: 20-30 participantsOutcomes: Study implementation (recruitment and attrition rates), quality of data collection at baseline and 4 months and ESI adherence (number of contacts, DNA and drop out) as per objectives 1a/bQualitative evaluation: Semi-structured interviews with up to 10 participants and ESI facilitators and focus group(s) (range of pharmacy staff n = 8-10) will be conducted to explore the acceptability of the intervention and feasibility of the study, training and study procedures. External pilot study: Objectives:Quantify the flow of participants (eligibility, recruitment and follow-up rate)Evaluate proposed recruitment, assessment and outcome measure collection methodsExamine the delivery of the enhanced support intervention in a community pharmacy setting (intervention uptake, retention and dose) to inform process evaluationProcess evaluation, using semi-structured interviews with participants across a range of socio-economic settings, and pharmacy staff to explore the acceptability of the ESI within community pharmacy, elements of the intervention that were considered useful (or not) and appropriateness of study proceduresDesign: Pilot randomised controlled trial, including a prospective economic and qualitative evaluationSetting: As abovePopulation: As aboveIntervention: As above with adaptations post feasibility studyComparator: Usual careSample size: 100 participantsOutcomes: Data will be used to estimate recruitment, intervention delivery and study completion rates as per objectives 2a-d. Definitive estimates of the effectiveness of ESI will not be made.Primary outcome: Depression severity (Patient Health Questionnaire 9) at four months.Secondary outcomes: Patient acceptance, uptake and attrition. ICD10 depression status, anxiety (GAD 7), health-related quality of life (SF-12v2) and health-state utility (EQ5D 3L) will be measured at four months.Economic evaluation: The incremental cost per QALY will be calculated from both the NHS and societal perspective.Process evaluation: Using mixed methods, potential mediators/moderators of the intervention, the acceptability (to participants and pharmacy staff), barriers and facilitators to the use of ESI in community pharmacy, and impact on usual practice will be examined. Semi-structured interviews with approximately 30 study participants, 20 pharmacy staff and eight GPs near participating pharmacies will be conducted.
