A Systematic Review of Inequalities in the Mental Health Experiences of Black African, Black Caribbean and Black-mixed UK Populations: Implications for Action.

BACKGROUND: Measurable differences in the experience and treatment of mental health conditions have been found to exist between different racial categories of community groups. The objective of this research was to review the reported mental health of Black African-Caribbean communities in the UK, determinants of mental health, and interventions to enhance their experiences of mental health services. METHOD: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement was applied. To be included, papers must be published in a peer reviewed journal; report on adult populations (over 18) from any of Black African, Black Caribbean or Black mixed people in the UK; and assess (quantitative), or discuss (qualitative) mental health experiences, determinants of mental health, or interventions intended to enhance experiences of mental health services among the target population. The aims, inclusion criteria, data extraction, and data quality evaluation were specified in advance. Searches were conducted using EBSCO (PsychInfo; MEDLINE; CINAHL Plus; psychology and behavioural sciences collection). The search strategy included search terms relating to the aim. Risk of bias was assessed using a standard tool, records were organised using Endnote, and data were extracted and synthesised using Microsoft Excel. RESULTS: Thirty-six studies were included, of which 26 were quantitative and six reported exclusively on Black participants. Black populations were less likely to access mental health support via traditional pathways due to stigma and mistrust of mental health services. Black Africans especially, sought alternative help from community leaders, which increased the likelihood of accessing treatment at the point of crisis or breakdown, which in turn increased risk of being detained under the Mental Health Act and via the criminal justice system. DISCUSSION: Findings suggest a cycle of poor mental health, coercive treatment, stigma, and mistrust of services as experienced by Black communities. Evidence was limited by poorly defined ethnic categories, especially where Black populations were subsumed into one category. It is recommended that mental health services work collaboratively with cultural and faith communities in supporting Black people to cope with mental illness, navigate mental health pathways, and provide culturally appropriate advice.

Development of a semi-quantitative scoring protocol for gill lesion assessment in greenlip abalone Haliotis laevigata held at elevated water temperature.

Water temperatures that exceed thermal optimal ranges (~19 to 22°C for greenlip abalone Haliotis laevigata, depending on stock genetics) can be associated with abalone mortalities. We assessed histopathological changes in H. laevigata gills held in control (22°C) or elevated (25°C) water temperature conditions for 47 d by developing a new scoring protocol that incorporates histopathological descriptions and relative score summary. Lesions were allocated to 1 of 3 reaction patterns, (1) epithelial, (2) circulatory or (3) inflammatory, and scored based on their prevalence in gill leaflets. Indices for each reaction pattern were calculated and combined to provide an overall gill index. H. laevigata held in 25°C water temperature had significantly more epithelial lifting and hemolymph channel enlargement and significantly higher gill and circulatory reaction pattern indices than H. laevigata held in 22°C water temperature. One H. laevigata had a proliferation of unidentified cells in the v-shaped skeletal rod of a gill leaflet. The unidentified cells contained enlarged nuclei, a greater nucleus:cytoplasm ratio and, in some cases, mitotic figures. This cell population could represent a region of hematopoiesis in response to hemocyte loss or migration to a lesion. Without thorough diagnostic testing, the origin of these larger cells cannot be confirmed. The new scoring protocol developed will allow the standard quantification of gill lesions for H. laevigata, specifically for heat-related conditions, and could further be adapted for other Haliotis spp.

Disclosure of lived experience of mental illness in training: Reasons for disclosure.

Students in mental health (MH) professions often face MH symptoms themselves related to the stress of graduate training and have been shown to benefit from supportive mentoring. Little is known, however, about trainees who already have a mental illness, and how best to help them succeed. Snowball sampling was used to survey 35 MH professionals with lived experience of mental illness (LE), also known as "prosumers." The survey included questions about participants' past disclosure about mental illness when they were in a training role. Questions were also asked about participants' experience supervising or teaching students who had disclosed LE. The survey included quantitative and qualitative data. Of participants who disclosed experiences of mental illness during past training, most disclosed to a clinical supervisor, with the most common reason for disclosure being to seek social support. A majority (83%) of those who endorsed having a trainee disclose to them were "out" about their own LE at the time. The majority of participants (78%) indicated they would like accessible examples of how others had dealt with trainee disclosure to use as a tool in working with trainees. We conclude with implications for future research and resources on this topic. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Prescribing fitness apps for people with cancer: a preliminary assessment of content and quality of commercially available apps.

PURPOSE: The benefits of physical activity for cancer survivors are increasingly recognised and smartphone applications are available to assist them to become more physically active. Cancer clinicians, however, lack confidence about which physical activity apps to recommend as evidence on their quality and content is limited. Therefore, we reviewed freely available commercial physical activity/fitness apps to systematically assess their behavioural change content and quality of their design. METHODS: Systematic searches of the app stores for Apple and Android operating systems were conducted and apps were screened to identify free apps appropriate for cancer survivors. Quality was assessed using the Mobile App Rating Scale (MARS) and behavioural content was evaluated using the Behavioural Change Techniques Taxonomy (BCTT). RESULTS: Of 341 apps identified, 67 were judged appropriate for cancer survivors and 46% combined aerobic and strength/stretching content. The overall number of behavioural change techniques (BCT) included was 3.96 (SD = 2.09), with the most frequent being 'feedback on behaviour' and 'goal setting behaviour'. The mean scores for objective and subjective quality were 4.11 (SD = 0.59) and 3.07 (SD = 0.91) respectively (range 0 to 5). Finally, a modest positive correlation was found between the number of BCT and the quality of engagement, awareness and knowledge as assessed by the MARS. CONCLUSION: Only a fifth of retrieved physical activity apps contained potentially suitable content for people affected by cancer. Overall, most apps we reviewed appeared to perform well in terms of their objective quality, but less well at promoting knowledge and awareness or help seeking related to physical activity. IMPLICATIONS FOR CANCER SURVIVORS: Many physical activity apps are available but the combined use of MARS and BCTT suggests that not all of them are suitable to the needs is a promising and feasible approach for assessing the applicability, usability and content of physical activity of apps employed by cancer survivors and this study is a first step toward developing a guide.

Visible spectroscopy diagnostics for tungsten source assessment in the WEST tokamak: First measurements.

The present work concerns the measurements obtained with the Tungsten (W) Environment in Steady-state Tokamak (WEST) visible spectroscopy system during the first experimental campaign. This system has been developed in the framework of the WEST project that equipped the existing Tore Supra device with a tungsten divertor in order to test actively cooled tungsten Plasma Facing Components (PFC) in view of preparing for ITER operation. The goal of this diagnostic is to measure the PFC sources and the deuterium recycling with spectral, spatial, and temporal resolution adapted to the predicted power deposition profiles on the objects observed. Three kinds of PFCs are monitored: the Ion Cyclotron Resonance Heating (ICRH) antenna and Low Hybrid Current Drive (LHCD) launcher W limiters; one of the 6 W inner bumpers; and the upper and lower W divertors. Large-aperture in-vessel actively cooled optical systems (f-number ∼ 3) were installed for each view and connected to optical fibres. A total of 240 optical fibers can be distributed on various detection systems including a fast response-time, multi-channel, filtered photodetector-based "Filterscope" system, developed by Oak Ridge National Laboratory (USA) as well as grating spectrometers optimized for multi-sightline analysis. The first WEST experimental campaign conducted in 2017 has been dedicated to plasma start-up development during which the visible spectroscopy system has provided crucial information related to the impurity content first and then impurity sources. The diagnostic setup for that first experimental campaign was limited to the inner bumper and outer limiters but was sufficient to demonstrate that the optical setup was in accordance with the specifications. The radiance calibration procedure allowed us to estimate fluxes from the main limiter of about 8 × 1018 atoms/(s m2) and to show a first W source radial profile along the outboard limiter.

Television food advertising viewed by preschoolers, children and adolescents: contributors to differences in exposure for black and white youth in the United States.

BACKGROUND: Public health experts raise concerns about adolescents' and black youth's greater exposure to TV advertising for unhealthy foods and beverages compared with children and white youth. OBJECTIVES: Examine how television-viewing patterns and rates of advertising during targeted programming contribute to this greater exposure. METHODS: Nielsen panel data provided viewing times and amount of food advertising viewed on U.S. television in 2008 and 2012. Researchers compared results by network type (black-, child- and youth-targeted), age group (preschoolers, children and adolescents) and race (black and white youth). RESULTS: Food advertising exposure increased with age for both black and white youth, but black youth viewed approximately 50% or more ads than did white youth of the same age. Higher rates of food advertising on youth-targeted networks explained greater adolescent exposure. However, greater television viewing and higher rates of advertising on youth- and black-targeted networks both contributed to black youth's greater exposure. From 2008 to 2012, increases in food-ads-per-hour increased exposure for all youth. CONCLUSIONS: Food advertisers and networks, especially those targeting adolescents and black youth, must do more to reduce advertising that negatively impacts young people's health. Furthermore, reducing commercial-television viewing by black youth may help reduce health disparities affecting their communities.

Rapid assessment with physical examination in dyspnoeic cats: the RAPID CAT study.

OBJECTIVES: To determine the underlying disease prevalence in acute feline dyspnoea and to examine whether historical and clinical examination findings can differentiate between acute cardiac and non-cardiac dyspnoea in cats in primary practice. MATERIALS AND METHODS: We prospectively enrolled cats presenting with dyspnoea for the first time to primary practice between June 1, 2011 and October 31, 2016. We collected signalment, historical and clinical data at presentation using a standard form. Cases were investigated by primary clinicians, and the final diagnosis was confirmed by the authors. Records lacking critical data were excluded. Relationships between historical or clinical variables and dyspnoea aetiology were examined. Diagnostic test performance analyses were used to find optimal cut-off values for select historical or clinical variables that could differentiate cardiac and non-cardiac dyspnoea. RESULTS: Participants included 108 cats. A definitive diagnosis was reached in 92 cases; 60 were cardiac (65%), 15 respiratory (16%), 10 neoplastic (11%) and 7 traumatic (8%). Of cats with cardiac dyspnoea, 25% had a history of cough. A gallop sound, rectal temperature less than 37·5°C, heart rate of greater than 200 bpm and respiratory rate greater than 80 per minute were all useful to predict cardiac-associated dyspnoea. A triage algorithm using these findings in combination was designed to optimise the rapid diagnosis of probable cardiac dyspnoea. CLINICAL SIGNIFICANCE: Dyspnoeic cats presenting in practice with hypothermia, tachycardia, gallop sounds or profound tachypnoea are likely to have a cardiac cause underlying their dyspnoea. Although diagnosis requires confirmation, clinicians may be able to stratify risk and prioritise further investigation based on these findings.

Bites by the Monocled Cobra, Naja kaouthia, in Chittagong Division, Bangladesh: Epidemiology, Clinical Features of Envenoming and Management of 70 Identified Cases.

AbstractWe describe 70 cases of monocled cobra (Naja kaouthia) bite admitted to Chittagong Medical College Hospital, Bangladesh. The biting snakes were identified by examining the dead snake and/or detecting N. kaouthia venom antigens in patients' serum. Bites were most common in the early morning and evening during the monsoon (May-July). Ligatures were routinely applied to the bitten limb before admission. Thirty-seven patients consulted traditional healers, most of whom made incisions around the bite site. Fifty-eight patients experienced severe neurotoxicity and most suffered swelling and pain of the bitten limb. The use of an Indian polyvalent antivenom in patients exhibiting severe neurotoxicity resulted in clinical improvement but most patients experienced moderate-to-severe adverse reactions. Antivenom did not influence local blistering and necrosis appearing in 19 patients; 12 required debridement. Edrophonium significantly improved the ability of patients to open the eyes, endurance of upward gaze, and peak expiratory flow rate suggesting that a longer-acting anticholinesterase drug (neostigmine) could be recommended for first aid. The study suggested that regionally appropriate antivenom should be raised against the venoms of the major envenoming species of Bangladesh and highlighted the need to improve the training of staff of local medical centers and to invest in the basic health infrastructure in rural communities.

Children's Hospital Characteristics and Readmission Metrics.

BACKGROUND AND OBJECTIVE: Like their adult counterparts, pediatric hospitals are increasingly at risk for financial penalties based on readmissions. Limited information is available on how the composition of a hospital's patient population affects performance on this metric and hence affects reimbursement for hospitals providing pediatric care. We sought to determine whether applying different readmission metrics differentially affects hospital performance based on the characteristics of patients a hospital serves. METHODS: We performed a cross-sectional analysis of 64 children's hospitals from the Children's Hospital Association Case Mix Comparative Database 2012 and 2013. We calculated 30-day observed-to-expected readmission ratios by using both all-cause (AC) and Potentially Preventable Readmissions (PPR) metrics. We examined the association between observed-to-expected rates and hospital characteristics by using multivariable linear regression. RESULTS: We examined a total of 1 416 716 hospitalizations. The mean AC 30-day readmission rate was 11.3% (range 4.3%-19.6%); the mean PPR rate was 4.9% (range 2.9%-6.9%). The average 30-day AC observed-to-expected ratio was 0.96 (range 0.63-1.23), compared with 0.95 (range 0.65-1.23) for PPR; 59% of hospitals performed better than expected on both measures. Hospitals with higher volumes, lower percentages of infants, and higher percentage of patients with low income performed worse than expected on PPR. CONCLUSIONS: High-volume hospitals, those that serve fewer infants, and those with a high percentage of patients from low-income neighborhoods have higher than expected PPR rates and are at higher risk of reimbursement penalties.

Current Status of Companion and Complementary Diagnostics: Strategic Considerations for Development and Launch.

US Food and Drug Administration (FDA)-approved diagnostic assays play an increasingly common role in managing patients to prolong lifespan while also enhancing quality of life. Diagnostic assays can be essential for the safe and effective use of therapeutics (companion diagnostic), or may inform on improving the benefit/risk ratio without restricting drug access (complementary diagnostic). This tutorial reviews strategic considerations for drug and assay development resulting in FDA-approved companion or complementary diagnostic status.

Development of visible spectroscopy diagnostics for W sources assessment in WEST.

The present work concerns the development of a W sources assessment system in the framework of the tungsten-W environment in steady state tokamak project that aims at equipping the existing Tore Supra device with a tungsten divertor in order to test actively cooled tungsten Plasma Facing Components (PFCs) in view of preparing ITER operation. The goal is to assess W sources and D recycling with spectral, spatial, and temporal resolution adapted to the PFCs observed. The originality of the system is that all optical elements are installed in the vacuum vessel and compatible with steady state operation. Our system is optimized to measure radiance as low as 1016 Ph/(m2 s sr). A total of 240 optical fibers will be deployed to the detection systems such as the "Filterscope," developed by Oak Ridge National Laboratory (USA) and consisting of photomultiplier tubes and filters, or imaging spectrometers dedicated to Multiview analysis.

Depth perception in disparity-defined objects: finding the balance between averaging and segregation.

Deciding what constitutes an object, and what background, is an essential task for the visual system. This presents a conundrum: averaging over the visual scene is required to obtain a precise signal for object segregation, but segregation is required to define the region over which averaging should take place. Depth, obtained via binocular disparity (the differences between two eyes' views), could help with segregation by enabling identification of object and background via differences in depth. Here, we explore depth perception in disparity-defined objects. We show that a simple object segregation rule, followed by averaging over that segregated area, can account for depth estimation errors. To do this, we compared objects with smoothly varying depth edges to those with sharp depth edges, and found that perceived peak depth was reduced for the former. A computational model used a rule based on object shape to segregate and average over a central portion of the object, and was able to emulate the reduction in perceived depth. We also demonstrated that the segregated area is not predefined but is dependent on the object shape. We discuss how this segregation strategy could be employed by animals seeking to deter binocular predators.This article is part of the themed issue 'Vision in our three-dimensional world'.

Prediction of changes in self-stigma among veterans participating in partial psychiatric hospitalization: The role of disability status and military cohort.

OBJECTIVE: Interventions addressing internalized stigma are a new area of research, and it is important to identify the types of clientele who derive benefit from existing interventions. METHOD: Information was provided by 235 veterans attending a partial psychiatric hospitalization program, regarding their levels of internalized stigma on admission and discharge from a 3-week program that included interventions targeting internalized stigma. RESULTS: Upon discharge, veterans receiving disability benefits demonstrated less reduction in internalized stigma than those not receiving disability benefits. Time of service moderated the relationship between disability status and change in internalized stigma, such that veterans serving in the more recent Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) cohort who received disability benefits had a more difficult time resolving internalized stigma. Further analyses suggested that OEF/OIF/OND cohort veterans receiving disability benefits have more difficulty developing effective stigma resistance, and more difficulty resolving stigma-related alienation, than other veterans. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Based on this research, particular attention should be devoted to internalized stigma among OEF/OIF/OND veterans.

Assessment of airway microbiota and inflammation in cystic fibrosis using multiple sampling methods.

RATIONALE: Oropharyngeal (OP) swabs and induced sputum (IS) are used for airway bacteria surveillance in nonexpectorating children with cystic fibrosis (CF). Molecular analyses of these airway samples detect complex microbial communities. However, the optimal noninvasive sampling approach for microbiota analyses and the clinical relevance of microbiota, particularly its relationship to airway inflammation, is not well characterized. OBJECTIVES: The goals of this study were to compare molecular analyses of concurrently collected saliva, OP swabs, IS, and expectorated sputum (ES) from children with CF and to determine the association between microbiota, lung function, and airway inflammation. METHODS: Saliva, OP swabs, IS, and ES were collected from 16 children with CF. Spirometry was performed. MEASUREMENTS AND MAIN RESULTS: Respiratory and saliva samples (n = 61) were sequenced for bacterial microbial communities, and total and CF-specific bacterial quantitative PCR assays were performed. Airway samples underwent conventional culture for CF-specific pathogens. Neutrophil elastase, IL-1ß, IL-1ra, IL-6, Il-8, TNF-α, and vascular endothelial growth factor were measured in ES and IS. Sequencing results from individual subjects were similar across samples, with greater between-subject than within-subject variation. However, Pseudomonas and Staphylococcus were detected in higher relative abundance from lower airways (ES and IS) compared with paired upper airway samples (OP and saliva). Pseudomonas, Staphylococcus, and Enterobacteriaceae correlated with increased airway inflammation. Divergence between microbiota in upper airway compared with lower airway samples, indicating greater differences between communities, was associated with increased sputum neutrophil elastase. CONCLUSIONS: Bacteria detected in IS samples resemble ES samples, whereas OP samples may underrepresent bacteria associated with airway inflammation. Divergence of lower airway communities from upper airway was associated with airway inflammation and may portend disease progression.

Food and beverage advertising on children's web sites.

BACKGROUND: Food marketing contributes to childhood obesity. Food companies commonly place display advertising on children's web sites, but few studies have investigated this form of advertising. OBJECTIVES: Document the number of food and beverage display advertisements viewed on popular children's web sites, nutritional quality of advertised brands and proportion of advertising approved by food companies as healthier dietary choices for child-directed advertising. METHODS: Syndicated Internet exposure data identified popular children's web sites and food advertisements viewed on these web sites from July 2009 through June 2010. Advertisements were classified according to food category and companies' participation in food industry self-regulation. The percent of advertisements meeting government-proposed nutrition standards was calculated. RESULTS: 3.4 billion food advertisements appeared on popular children's web sites; 83% on just four web sites. Breakfast cereals and fast food were advertised most often (64% of ads). Most ads (74%) promoted brands approved by companies for child-directed advertising, but 84% advertised products that were high in fat, sugar and/or sodium. Ads for foods designated by companies as healthier dietary choices appropriate for child-directed advertising were least likely to meet independent nutrition standards. CONCLUSIONS: Most foods advertised on popular children's web sites do not meet independent nutrition standards. Further improvements to industry self-regulation are required.

Inpatient utilization before and after implementation of psychosocial rehabilitation programs: analysis of cost reductions.

Research on psychosocial rehabilitation (PSR) interventions generally indicates that these approaches are effective in facilitating improved functioning for persons with serious mental illness (SMI; schizophrenia, schizoaffective disorder, bipolar disorder, and other psychotic disorders). In this quasi-experimental study, we assessed the effectiveness of PSR interventions through a records review of 311 veterans who received outpatient services for SMI. From 2002 to 2008, a midwestern VA Medical Center implemented a number of PSR interventions. By 2008, veterans who used PSR interventions demonstrated reductions in their use of inpatient psychiatric care, whereas veterans who did not access PSR interventions showed no change in inpatient psychiatric care use. Analyses revealed that the provision of PSR services to veterans with SMI who had been hospitalized was associated with decreased duration of hospitalizations and costs savings of $17,739 per veteran per year in total mental health care. Findings are consistent with implementation of PSR programs within VA Medical Centers yielding the greatest cost savings through creation of effective outpatient services that reduce inpatient service needs for veterans with SMI.

Developing and testing TEAM (Team Evaluation and Assessment Measure), a self-assessment tool to improve cancer multidisciplinary teamwork.

BACKGROUND: Cancer multidisciplinary teams (MDTs) are well established worldwide and are an expensive resource yet no standardised tools exist to measure performance. We aimed to develop and test an MDT self-assessment tool underpinned by literature review and consensus from over 2000 UK MDT members about the "characteristics of an effective MDT." METHODS: Questionnaire items relating to all characteristics of MDTs (particularly Leadership and Chairing; Teamworking and Culture; Patient-centred care; Clinical decision-making process; and Organisation and administration during meetings) were developed by an expert panel. Acceptability, feasibility and psychometric properties were tested by online completion of the questionnaire by 23 MDTs from 4 UK NHS Trusts followed by interviews with 74 team members including members from all teams and nonresponders. 10 of the MDTs also completed questionnaires that directly translated each characteristic to an item (for the five domains above) to test content validity. RESULTS: A total of 47 items were created, each rated for agreement on a 5-point scale. A total of 329 (52 %) of 637 team members completed the questionnaire, including representation from medical, nursing and clerical MDT members. Responses correlated well with domain-specific questionnaires (r > 0.67, p = 0.01), most domain-scales had acceptable internal consistency (Cronbach alpha > 0.60), and good item discrimination (majority of items r < 0.20). Team members were positive about its value. CONCLUSIONS: Self-assessment of team performance using this tool may support MDT development.

Adaptive e-learning to improve dietary behaviour: a systematic review and cost-effectiveness analysis.

BACKGROUND: UK public health policy strongly advocates dietary change for the improvement of population health and emphasises the importance of individual empowerment to improve health. A new and evolving area in the promotion of dietary behavioural change is 'e-learning', the use of interactive electronic media to facilitate teaching and learning on a range of issues including health. The high level of accessibility, combined with emerging advances in computer processing power, data transmission and data storage, makes interactive e-learning a potentially powerful and cost-effective medium for improving dietary behaviour. OBJECTIVE: This review aims to assess the effectiveness and cost-effectiveness of adaptive e-learning interventions for dietary behaviour change, and also to explore potential psychological mechanisms of action and components of effective interventions. DATA SOURCES: Electronic bibliographic databases (Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library, Dissertation Abstracts, EMBASE, Education Resources Information Center, Global Health, Health Economic Evaluations Database, Health Management Information Consortium, MEDLINE, PsycINFO and Web of Science) were searched for the period January 1990 to November 2009. Reference lists of included studies and previous reviews were also screened; authors were contacted and trial registers were searched. REVIEW METHODS: Studies were included if they were randomised controlled trials, involving participants aged ≥ 13 years, which evaluated the effectiveness of interactive software programs for improving dietary behaviour. Primary outcomes were measures of dietary behaviours, including estimated intakes or changes in intake of energy, nutrients, dietary fibre, foods or food groups. Secondary outcome measures were clinical outcomes such as anthropometry or blood biochemistry. Psychological mediators of dietary behaviour change were also investigated. Two review authors independently screened results and extracted data from included studies, with any discrepancies settled by a third author. Where studies reported the same outcome, the results were pooled using a random-effects model, with weighted mean differences (WMDs), and 95% confidence intervals (CIs) were calculated. Cost-effectiveness was assessed in two ways: through a systematic literature review and by building a de novo decision model to assess the cost-effectiveness of a 'generic' e-learning device compared with dietary advice delivered by a health-care professional. RESULTS: A total of 36,379 titles were initially identified by the electronic searches, of which 43 studies were eligible for inclusion in the review. All e-learning interventions were delivered in high-income countries. The most commonly used behavioural change techniques reported to have been used were goal setting; feedback on performance; information on consequences of behaviour in general; barrier identification/problem solving; prompting self-monitoring of behaviour; and instruction on how to perform the behaviour. There was substantial heterogeneity in the estimates of effect. E-learning interventions were associated with a WMD of +0.24 (95% CI 0.04 to 0.44) servings of fruit and vegetables per day; -0.78 g (95% CI -2.5 g to 0.95 g) total fat consumed per day; -0.24 g (95% CI -1.44 g to 0.96 g) saturated fat intake per day; -1.4% (95% CI -2.5% to -0.3%) of total energy consumed from fat per day; +1.45 g (95% CI -0.02 g to 2.92 g) dietary fibre per day; +4 kcal (95% CI -85 kcal to 93 kcal) daily energy intake; -0.1 kg/m2 (95% CI -0.7 kg/m2 to 0.4 kg/m2) change in body mass index. The base-case results from the E-Learning Economic Evaluation Model suggested that the incremental cost-effectiveness ratio was approximately £102,112 per quality-adjusted life-year (QALY). Expected value of perfect information (EVPI) analysis showed that although the individual-level EVPI was arguably negligible, the population-level value was between £37M and £170M at a willingness to pay of £20,000-30,000 per additional QALY. LIMITATIONS: The limitations of this review include potential reporting bias, incomplete retrieval of completed research studies and data extraction errors. CONCLUSION: The current clinical and economic evidence base suggests that e-learning devices designed to promote dietary behaviour change will not produce clinically significant changes in dietary behaviour and are at least as expensive as other individual behaviour change interventions. FUTURE WORK RECOMMENDATIONS: Despite the relatively high EVPI results from the cost-effectiveness modelling, further clinical trials of individual e-learning interventions should not be undertaken until theoretically informed work that addresses the question of which characteristics of the target population, target behaviour, content and delivery of the intervention are likely to lead to positive results, is completed.

Common mental disorders, unemployment and welfare benefits in England.

OBJECTIVES: Individuals who are out of work have a higher rate of common mental disorders (CMD) than individuals who are employed. People who are unemployed in the UK are entitled to welfare benefits to alleviate financial strain. This study examined rates of CMD in individuals who were employed, unemployed and receiving various UK benefits. It also investigated associations between duration of unemployment, gender and CMD. STUDY DESIGN: An analysis of 5090 working-age participants from the Adult Psychiatric Morbidity Survey 2007, a stratified probability sample survey conducted among adults aged 16 years and over living in private households in England. METHODS: CMD was assessed using the Clinical Interview Schedule (Revised). Information was gathered on sociodemographics, employment, income, benefits and debt. Data were analysed using logistic regression. RESULTS: Risk of CMD was significantly greater in individuals classified as: unemployed; economically inactive; not working due to physical health reasons; unable to find a suitable job; receiving housing, care or sickness benefit; and receiving income support. However, risk of CMD was not significantly greater in individuals receiving jobseeker's allowance. Individuals unemployed for less than 1 year or more than 3 years had a higher risk of CMD. Some interactions with gender were significant, with associations being greater in men than women. CONCLUSIONS: Job loss events are not the only reason for unemployed people to develop CMD. The state of unemployment itself may be detrimental to mental health. Risk of CMD is increased in those who have been out of work for 3 years or more. Associations between benefits and mental health are likely to be due to social, health or economic circumstances associated with benefit eligibility.
