RESUMEN
During lactation, changes in maternal calcium metabolism are necessary to provide adequate calcium for newborn skeletal development. The calcium in milk is derived from the maternal skeleton through a process thought to be mediated by the actions of parathyroid hormone-related protein (PTHrP) in combination with decreased circulating estrogen concentrations. After weaning, bone lost during lactation is rapidly regained. Most studies of bone metabolism in lactating women have been performed in Caucasian subjects. There are well-documented differences between African American (AA) and Caucasian (C) bone metabolism, including higher bone mineral density (BMD), lower risk of fracture, lower 25-hydroxyvitamin D (25(OH) D), and higher PTH in AA compared to C. In this prospective paired cohort study, BMD and markers of bone turnover were compared in self-identified AA and C mothers during lactation and after weaning. BMD decreased in both AA and C women during lactation, with similar decreases at the lumbar spine (LS) and greater bone loss in the C group at the femoral neck (FN) and total hip (TH), demonstrating that AA are not resistant to PTHrP during lactation. BMD recovery compared to the 2 week postpartum baseline was observed 6 months after weaning, though the C group did not have complete recovery at the FN. Increases in markers of bone formation and resorption during lactation were similar in AA and C. C-terminal telopeptide (CTX) decreased to 30% below post-pregnancy baseline in both groups 6 months after weaning, while procollagen type 1 N-terminal (P1NP) returned to baseline in the AA group and fell to below baseline in the C group. Further investigation is required to determine impacts on long term bone health for women who do not fully recover BMD before a subsequent pregnancy.

Background: Tobacco use amongst adolescents causes significant health problems affecting almost all organs and has a significant effect on normal growth and development. Smoker adolescents are also more prone to oral health problems than nonsmokers. Pediatric dentists can play a significant role in providing tobacco cessation counseling to adolescents. Aim: To assess the knowledge (K), perceptions (PR), training, and practices (PE) of pediatric dentists related to the provision of tobacco cessation interventions. Materials and methods: A cross-sectional online survey with convenience sampling was planned to assess the K, PR, training, and PE of pediatric dentists across the globe in dealing with tobacco menace amongst adolescents. The survey was done through a self-administered questionnaire in the form of an online Google Form. The study population consisted of pediatric dentists attending the International Academy of Pediatric Dentistry (IAPD) virtual conference 2021. Results: A total of 1,564 participants were targeted and 235 answered the survey with a response rate of 15.02%. Attending tobacco cessation intervention (p ≤ 0.001) and training in postgraduation on tobacco cessation (p ≤ 0.002) showed significant association with favorable practice scores. However, in the PR domain age in years (p ≤ 0.043), country of residence (continent, p ≤ 0.001) was found to be significantly associated with attending tobacco cessation intervention (p < 0.001) and training in postgraduation (p < 0.001). Conclusion: The results of the study emphasize the need for recommendations for educating pediatric dentists by the inclusion of tobacco cessation interventions in the core curriculum, continuing dental education programs, and promoting professional responsibility to help achieve tobacco-free youth all across the globe.

RESUMEN
BACKGROUND: People with psychosis experience cardiometabolic comorbidities, including metabolic syndrome, coronary heart disease and diabetes. These physical comorbidities have been linked to diet, inactivity and the effects of the illness itself, including disorganisation, impairments in global function and amotivation associated with negative symptoms of schizophrenia or co-morbid depression. METHODS: We aimed to describe the dietary intake, physical activity (PA) and sedentary behaviour patterns of a sample of patients with established psychosis participating in the Improving Physical Health and Reducing Substance Use in Severe Mental Illness (IMPaCT) randomised controlled trial, and to explore the relationship between these lifestyle factors and mental health symptomatology. RESULTS: A majority of participants had poor dietary quality, low in fruit and vegetables and high in discretionary foods. Only 29.3% completed ⩾150 min of moderate and/or vigorous activity per week and 72.2% spent ⩾6 h per day sitting. Cross-sectional associations between negative symptoms, global function, and PA and sedentary behaviour were observed. Additionally, those with more negative symptoms receiving IMPaCT therapy had fewer positive changes in PA from baseline to 12-month follow-up than those with fewer negative symptoms at baseline. CONCLUSION: These results highlight the need for the development of multidisciplinary lifestyle and exercise interventions to target eating habits, PA and sedentary behaviour, and the need for further research on how to adapt lifestyle interventions to baseline mental status. Negative symptoms in particular may reduce patient's responses to lifestyle interventions.

BACKGROUND: Patients with psychotic disorders show higher rates of the metabolic syndrome (MS) between the cluster of severe mental illnesses. Depressive symptoms can worsen outcomes of individuals with psychotic disorders. However, research on the association between MS and depression in psychotic disorders and their relevance to outcomes is lacking. METHODS: We investigated the association between depression and cardiometabolic biomarkers in psychotic disorders and the predictive value of depressive symptoms on psychopathological severity and quality of life (QoL). 406 patients with psychotic disorders were recruited as part of the Improving Physical Health and Reducing Substance Use in Severe Mental Illness randomised controlled trial. Depression, psychotic symptoms, QoL, waist circumference, triglycerides, high-density lipoprotein cholesterol (HDL-C), blood pressure, and fasting glucose of patients were assessed at baseline and 12 months. Sensitivity analyses were conducted to test the effect of treatment. RESULTS: More severe baseline symptoms of depression significantly predicted worse 12-month psychotic symptoms and lower mental health related QoL at 12 months. These associations held after controlling for alcohol use, gender, ethnicity, education, and mental health related QoL Baseline. Depressive symptoms also correlated with waist circumference at both baseline and 12 months, after controlling for multiple testing. CONCLUSION: Individuals with psychotic disorders experiencing more severe depressive symptoms are more likely to have larger waist circumference contemporaneously and 12 months later, as well as more severe psychotic symptoms and worse QoL at follow-up. This highlights the need for evaluation of strategies to address depression in the management of psychotic disorders.

Importance: People with psychotic disorders have an increased risk of vitamin D deficiency, which is evident during first-episode psychosis (FEP) and associated with unfavorable mental and physical health outcomes. Objective: To examine whether vitamin D supplementation contributes to improved clinical outcomes in FEP. Design, Setting, and Participants: This multisite, double-blind, placebo-controlled, parallel-group randomized clinical trial from the UK examined adults 18 to 65 years of age within 3 years of a first presentation with a functional psychotic disorder who had no contraindication to vitamin D supplementation. A total of 2136 patients were assessed for eligibility, 835 were approached, 686 declined participation or were excluded, 149 were randomized, and 104 were followed up at 6 months. The study recruited participants from January 19, 2016, to June 14, 2019, with the final follow-up (after the last dose) completed on December 20, 2019. Interventions: Monthly augmentation with 120â¯000 IU of cholecalciferol or placebo. Main Outcomes and Measures: The primary outcome measure was total Positive and Negative Syndrome Scale (PANSS) score at 6 months. Secondary outcomes included total PANSS score at 3 months; PANSS positive, negative, and general psychopathology subscale scores at 3 and 6 months; Global Assessment of Function scores (for symptoms and disability); Calgary Depression Scale score, waist circumference, body mass index, and glycated hemoglobin, total cholesterol, C-reactive protein, and vitamin D concentrations at 6 months; and a planned sensitivity analysis in those with insufficient vitamin D levels at baseline. Results: A total of 149 participants (mean [SD] age, 28.1 (8.5) years; 89 [59.7%] male; 65 [43.6%] Black or of other minoritized racial and ethnic group; 84 [56.4%] White [British, Irish, or of other White ethnicity]) were randomized. No differences were observed in the intention-to-treat analysis in the primary outcome, total PANSS score at 6 months (mean difference, 3.57; 95% CI, -1.11 to 8.25; P = .13), or the secondary outcomes at 3 and 6 months (PANSS positive subscore: mean difference, -0.98; 95% CI, -2.23 to 0.27 at 3 months; mean difference, 0.68; 95% CI, -0.69 to 1.99 at 6 months; PANSS negative subscore: mean difference, 0.68; 95% CI, -1.39 to 2.76 at 3 months; mean difference, 1.56; 95% CI, -0.31 to 3.44 at 6 months; and general psychopathology subscore: mean difference, -2.09; 95% CI, -4.36 to 0.18 at 3 months; mean difference, 1.31; 95% CI, -1.42 to 4.05 at 6 months). There also were no significant differences in the Global Assessment of Function symptom score (mean difference, 0.02; 95% CI, -4.60 to 4.94); Global Assessment of Function disability score (mean difference, -0.01; 95% CI, -5.25 to 5.23), or Calgary Depression Scale score (mean difference, -0.39; 95% CI, -2.05 to 1.26) at 6 months. Vitamin D levels were very low in the study group, especially in Black participants and those who identified as another minoritized racial and ethnic group, 57 of 61 (93.4%) of whom had insufficient vitamin D. The treatment was safe and led to a significant increase in 25-hydroxyvitamin D concentrations. Conclusions and Relevance: In this randomized clinical trial, no association was found between vitamin D supplementation and mental health or metabolic outcomes at 6 months. Because so few patients with FEP were vitamin D replete, the results of this study suggest that this group would benefit from active consideration in future population health strategies.

Unsupervised marketing strategies of alternative smoke have made the youth fall prey to herbal smoke in the form of herbal cigarettes and hookahs. The easy online access, exotic looks, and flavors; marketed as safer, healthy alternatives, as an aid to quit smoking has made global herbal cigarette and hookah market see soaring sales in the past decade. Various studies have proven their popularity among the youth and minors with perceptions of being safer and smart alternatives. The scientific studies have shown that herbal smoke is as harmful as tobacco smoke. The marketing strategies of smoke industry to capture the minors and young adults could result in another stronger lobby besides tobacco to be dealt with in coming years. This creates an urgent need for the laws to be reviewed and amended keeping in view the changing scenario.

BACKGROUND: People experiencing their first episode of psychosis are often deficient in vitamin D. Observational studies have reported an association between low vitamin D concentrations and poorer subsequent health outcomes in psychosis. A vitamin D deficiency in neonates and children has been linked to a later increased risk of schizophrenia and psychotic-like experiences. This trial aims to examine the effect of high-dose vitamin D supplementation on outcomes in early psychosis. We hypothesise that vitamin D supplementation will be associated with better mental health outcomes. METHODS/DESIGN: The DFEND study is a multicentre double-blind placebo-controlled parallel-group trial of vitamin D supplementation in people with early psychosis. Patients with an ICD-10 diagnosis of functional psychosis will be randomised in a 1:1 ratio to receive either 120,000 IU/month of vitamin D (cholecalciferol) or a matched placebo for 6 months. The primary outcome is the total Positive and Negative Syndrome Scale (PANSS) score at the 6-month follow-up for all patients. Secondary outcomes include assessment of mood (Calgary Depression Scale), general function (Global Assessment of Functioning), cardiovascular risk (body mass index, waist circumference, C-reactive protein, cholesterol and HbA1c) and vitamin D levels at the 6-month follow-up. Additionally, 3- and 6-month total PANSS scores will be analysed for those with inadequate vitamin D levels at the baseline. DISCUSSION: The DFEND study is the first trial to examine whether vitamin D supplementation in early psychosis is associated with better mental health outcomes. The findings of this study may help to resolve the clinical equipoise regarding the benefits and cost-effectiveness of routine vitamin D supplementation in people with psychosis. TRIAL REGISTRATION: ISRCTN, ISRCTN12424842. Registered on 25 February 2015.

BACKGROUND: Empathy is just as relevant within dentistry, although research is limited in this field and very less is available in the current literature. The demonstration of empathy by dentists has been correlated with decreased dental fear. The authors systematically reviewed the literature to investigate empathy levels among dental students. METHODS: A systematic review of the literature was undertaken concerning dental students' empathy, published from November 2016 to June 2018, using manual methods and the PubMed, PMC, PsycINFO, and other databases. Articles not in English and not concerned with dentistry were excluded, and intervention studies intended to enhance empathy, opinion articles, and reviews or reports of nonoriginal research were excluded. Eligible studies were those published from January 1, 2005, to May 31, 2017, in English language. A total of 34 full-text articles were obtained and assessed. Of these 34 papers, only seven publications were considered to have met the inclusion criteria and were directly related to the aim of literature search. RESULTS: Only seven articles that provided data and evidence describing empathy among dental students were included. Four studies reported that the difference in mean empathy level across the year of study was statistically significant (P < 0.05), and one reported that there was no significant difference in empathy scores between the year levels of study. Three articles reported that males had higher mean empathy score than females, whereas vice versa was found in the remaining four articles. CONCLUSION: This article demonstrates that there is only a limited evidence to provide the understanding of empathy among dental students. The results indicated that as patient exposure increases, the empathy level decreases among dental students. Furthermore, it is observed that education in behavioral sciences may be effective in increasing self-reported empathy, and further training may be necessary to maintain high levels.

BACKGROUND: The first episode of psychosis is a critical period in the emergence of cardiometabolic risk. AIMS: We set out to explore the influence of individual and lifestyle factors on cardiometabolic outcomes in early psychosis. METHOD: This was a prospective cohort study of 293 UK adults presenting with first-episode psychosis investigating the influence of sociodemographics, lifestyle (physical activity, sedentary behaviour, nutrition, smoking, alcohol, substance use) and medication on cardiometabolic outcomes over the following 12 months. RESULTS: Rates of obesity and glucose dysregulation rose from 17.8% and 12%, respectively, at baseline to 23.7% and 23.7% at 1 year. Little change was seen over time in the 76.8% tobacco smoking rate or the quarter who were sedentary for over 10 h daily. We found no association between lifestyle at baseline or type of antipsychotic medication prescribed with either baseline or 1-year cardiometabolic outcomes. Median haemoglobin A1c (HbA1c) rose by 3.3 mmol/mol in participants from Black and minority ethnic (BME) groups, with little change observed in their White counterparts. At 12 months, one-third of those with BME heritage exceeded the threshold for prediabetes (HbA1c >39 mmol/mol). CONCLUSIONS: Unhealthy lifestyle choices are prevalent in early psychosis and cardiometabolic risk worsens over the next year, creating an important window for prevention. We found no evidence, however, that preventative strategies should be preferentially directed based on lifestyle habits. Further work is needed to determine whether clinical strategies should allow for differential patterns of emergence of cardiometabolic risk in people of different ethnicities.

AIM: People with psychotic disorders have increased premature mortality in comparison with the general population, with high rates of cigarette use a contributing factor. We aimed to describe the prevalence of cigarette use and nicotine dependence (ND) in first episode psychosis (FEP), and established psychosis; and to investigate associations between clinical symptoms and ND. METHODOLOGY: Smoking and clinical data were collected from two cohorts: 181 people with FEP recruited as part of the Physical Health and Substance Use Measures in First Onset Psychosis (PUMP) study and from 432 people with established psychosis recruited as part of the Improving physical health and reducing substance use in psychosis randomised controlled trial (IMPaCT RCT). RESULTS: The prevalence of cigarette smoking was 78% in FEP and 62% in established psychosis. Forty nine percent (n = 60) of smokers in the FEP cohort and 69% (n = 183) of smokers with established psychosis were highly nicotine dependent. Being a highly nicotine dependent smoker was significantly associated with higher PANSS positive symptom scores (F = 5.480 p = 0.004), and with decreased scores on the Rosenberg self-esteem scale (F = 3.261, p = 0.039) in established psychosis. There was no diagnostic specificity identified in relation to smoking or ND in both groups. CONCLUSION: High rates of cigarette usage and nicotine dependence are problems from the early stages of psychosis. ND is higher in people with established psychosis. Smoking cessation strategies as part of comprehensive management of psychotic disorders at every stage require further development and evaluation.

BACKGROUND: Jumping to conclusions (JTC), which is the proneness to require less information before forming beliefs or making a decision, has been related to formation and maintenance of delusions. Using data from the National Institute of Health Research Biomedical Research Centre Genetics and Psychosis (GAP) case-control study of first-episode psychosis (FEP), we set out to test whether the presence of JTC would predict poor clinical outcome at 4 years. METHODS: One-hundred and twenty-three FEP patients were assessed with the Positive and Negative Syndrome Scale (PANSS), Global Assessment of Functioning (GAF) and the probabilistic reasoning 'Beads' Task at the time of recruitment. The sample was split into two groups based on the presence of JTC bias. Follow-up data over an average of 4 years were obtained concerning clinical course and outcomes (remission, intervention of police, use of involuntary treatment - the Mental Health Act (MHA) - and inpatient days). RESULTS: FEP who presented JTC at baseline were more likely during the follow-up period to be detained under the MHA [adjusted OR 15.62, 95% confidence interval (CI) 2.92-83.54, p = 0.001], require intervention by the police (adjusted OR 14.95, 95% CI 2.68-83.34, p = 0.002) and have longer admissions (adjusted IRR = 5.03, 95% CI 1.91-13.24, p = 0.001). These associations were not accounted for by socio-demographic variables, IQ and symptom dimensions. CONCLUSIONS: JTC in FEP is associated with poorer outcome as indicated and defined by more compulsion police intervention and longer periods of admission. Our findings raise the question of whether the implementation of specific interventions to reduce JTC, such as Metacognition Training, may be a useful addition in early psychosis intervention programmes.

BACKGROUND: There is a paucity of longitudinal research investigating vitamin D in people with early psychosis. METHOD: Vitamin D levels were measured in 168 patients (64% (nâ¯=â¯108) male, mean age 29.3 (9.8) years) with first episode psychosis (FEP), along with measures of clinical state at baseline and at 12â¯months follow up. We assessed the a) cross sectional, and; b) longitudinal relationships between continuous and categorical 25-hydroxyvitamin D (25(OH)D) levels and clinical symptoms at first contact for psychosis and at 12â¯months. RESULTS: In FEP, 80% (nâ¯=â¯134) at baseline, and 76% at 12â¯months follow up, had suboptimal vitamin D levels (<20â¯ng/ml). Suboptimal levels of 25 (OH) D at baseline were not cross-sectionally associated with clinical symptoms. Higher vitamin D levels at baseline (nâ¯=â¯77) were significantly associated with better visual reproduction-immediate recall (ßâ¯=â¯0.249, 95%CIâ¯=â¯-0.012-0.871, pâ¯=â¯0.044). Higher baseline vitamin D levels were prospectively associated with lower total PANSS (ßâ¯=â¯-0.24, 95%CIâ¯=â¯-0.47-0.01, pâ¯=â¯0.04) and PANSS negative symptom scores (ßâ¯=â¯-0.12, 95%CIâ¯=â¯-0.23-0.01, pâ¯=â¯0.04) at 12â¯months. CONCLUSION: We identified a prospective association between higher baseline serum Vitamin D levels and lower total psychotic symptoms and negative symptoms of psychosis at 12â¯months after first contact for psychosis. The results of this study require replication in larger prospective studies, and highlight the need for large randomised trials to assess the effect of vitamin D supplementation on symptoms of psychosis in FEP.

Introduction: Cardiovascular morbidity and mortality are increased in severe mental illnesses (SMI). Trials of psychosocial health interventions to improve physical health in SMI, including in treatment-resistant schizophrenia, have shown some benefit. However, the representativeness of participants in such trials has not been determined. Method: We utilized an anonymised case register to determine if participants in a randomized controlled trial (RCT) of a novel psychosocial health intervention aiming to improve physical health in SMI had similar severity of illness to eligible non-participants. A retrospective database analysis was performed, using Health of the Nation Outcome Scale (HoNOS) data from the sample of patients participating in the IMPaCT (Improving Physical health and reducing substance use in Psychosis) RCT (n = 293) compared to all eligible participants with a psychotic illness (n = 774). Results: The mean total HoNOS score in the eligible comparator population (Mean = 9.09, SD = 5.8, range = 0-30) was significantly greater than that of the IMPaCT RCT participants (Mean = 7.16, SD = 4.7, range = 0-26), (t = 3.810, p = 0.006), as was the degree of overall illness severity and functional impairment, as measured by HoNOS. Conclusion: This study shows for the first time that the patient population participating in an RCT of a lifestyle intervention for those with SMI had a better mental health status at entry to the trial, than the total eligible population, although there was no difference in physical health needs. This has relevance to the applicability of RCTs of lifestyle interventions in service planning and suggests that when people are more unwell, greater effort may be needed to include them in psychosocial interventions. A more careful and focused recruitment approach should be followed to improve the participation of the more severely ill patients in psychosocial interventions in order to enhance the external validity of such studies.
RESUMEN
Little is known about the impact of different forms of childhood adversity on outcomes in first-episode psychosis (FEP) patients beyond the first year of treatment. We investigated associations between different types of childhood adversity and outcomes of FEP patients over the 5 years following their first contact with mental health services for psychosis. 237 FEP cases aged 18-65 years were followed on average for 5 years after first presentation to psychiatric services in South London, UK. Childhood adversity prior to 17 years of age was assessed at baseline using the Childhood Experience of Care and Abuse Questionnaire (CECA.Q). The results showed that exposure to at least one type of childhood adversity was significantly associated with a lower likelihood of achieving symptomatic remission, longer inpatient stays, and compulsory admission over the 5-year follow-up. There was no evidence though of a dose-response effect. Some specificity was evident. Childhood parental separation was associated with significantly greater likelihood of non-compliance with antipsychotic medications, compulsory admission, and substance dependence. Institutional care was significantly associated with longer total length of inpatient stays; and parental death was significantly associated with compulsory admissions. Clinicians should screen FEP patients for childhood adversity and tailor interventions accordingly to improve outcomes.

BACKGROUND: There has been much recent excitement about the possibility that some cases of psychosis may be wholly due to brain-reactive antibodies, with antibodies to N-methyl-D-aspartate receptor (NMDAR) and the voltage-gated potassium channel (VGKC)-complex reported in a few patients with first-episode psychosis (FEP). METHODS: Participants were recruited from psychiatric services in South London, UK, from 2009 to 2011 as part of the Genetics and Psychosis study. We conducted a case-control study to examine NMDAR and VGKC-complex antibody levels and rates of antibody positivity in 96 patients presenting with FEP and 98 controls matched for age and sex. Leucine-rich glioma inactiviated-1 (LGI1) and contactin-associated protein (CASPR) antibodies were also measured. Notably, patients with suspicion of organic disease were excluded. RESULTS: VGKC-complex antibodies were found in both cases (n = 3) and controls (n = 2). NMDAR antibody positivity was seen in one case and one control. Either LGI1-Abs or CASPR2-Abs were found in three cases and three controls. Neuronal antibody staining, consistent with the above results or indicating potential novel antigens, was overall positive in four patients but also in six controls. Overall, antibody positivity was at low levels only and not higher in cases than in controls. CONCLUSIONS: This case-control study of the prevalence of antibodies in FEP does not provide evidence to support the hypothesis that FEP is associated with an immune-mediated process in a subgroup of patients. Nevertheless, as other bio-clinical factors may influence the effect of such antibodies in a given individual, and patients with organic neurological disease may be misdiagnosed as FEP, the field requires more research to put these findings in context.

There has been much recent debate concerning the relative clinical utility of symptom dimensions versus conventional diagnostic categories in patients with psychosis. We investigated whether symptom dimensions rated at presentation for first-episode psychosis (FEP) better predicted time to first remission than categorical diagnosis over a four-year follow-up. The sample comprised 193 FEP patients aged 18-65years who presented to psychiatric services in South London, UK, between 2006 and 2010. Psychopathology was assessed at baseline with the Positive and Negative Syndrome Scale and five symptom dimensions were derived using Wallwork/Fortgang's model; baseline diagnoses were grouped using DSM-IV codes. Time to start of first remission was ascertained from clinical records. The Bayesian Information Criterion (BIC) was used to find the best fitting accelerated failure time model of dimensions, diagnoses and time to first remission. Sixty percent of patients remitted over the four years following first presentation to psychiatric services, and the average time to start of first remission was 18.3weeks (SD=26.0, median=8). The positive (BIC=166.26), excited (BIC=167.30) and disorganised/concrete (BIC=168.77) symptom dimensions, and a diagnosis of schizophrenia (BIC=166.91) predicted time to first remission. However, a combination of the DSM-IV diagnosis of schizophrenia with all five symptom dimensions led to the best fitting model (BIC=164.35). Combining categorical diagnosis with symptom dimension scores in FEP patients improved the accuracy of predicting time to first remission. Thus our data suggest that the decision to consign symptom dimensions to an annexe in DSM-5 should be reconsidered at the earliest opportunity.

BACKGROUND: There is mounting evidence that people with severe mental illness have unhealthy lifestyles, high rates of cardiovascular and metabolic diseases, and greater risk of early mortality. This study aimed to assess the cost-effectiveness of a health promotion intervention seeking to improve physical health and reduce substance use in people with psychosis. METHODS: Participants with a psychotic disorder, aged 18-65 years old and registered on an enhanced care approach programme or equivalent were recruited from community mental health teams in six mental health trusts in England. Participants were randomisation to either standard community mental health team care (treatment as usual) or treatment as usual with an integrated health promotion intervention (IMPaCT). Cost-effectiveness and cost-utility analyses from health and social care and societal perspectives were conducted alongside a cluster randomised controlled trial. Total health and social care costs and total societal costs at 12 and 15 months were calculated as well as cost-effectiveness (incremental cost-effectiveness ratios and cost-effectiveness acceptability curves) at 15 months based on quality of life (SF-36 mental and physical health components, primary outcome measures) and quality adjusted life years (QALYs) using two measures, EQ-5D-3 L and SF-36. Data were analysed using bootstrapped regressions with covariates for relevant baseline variables. RESULTS: At 12-15 months 301 participants had full data needed to be included in the economic evaluation. There were no differences in adjusted health and social care costs (£95, 95% CI -£1410 to £1599) or societal costs (£675, 95% CI -£1039 to £2388) between the intervention and control arms. Similarly, there were no differences between the groups in the SF-36 mental component (-0.80, 95% CI -3.66 to 2.06), SF-36 physical component (-0.68, 95% CI -3.01 to 1.65), QALYs estimated from the SF-36 (-0.00, -0.01 to 0.00) or QALYs estimated from the EQ-5D-3 L (0.00, 95% CI -0.01 to 0.02). Cost-effectiveness acceptability curves for all four outcomes and from both cost perspectives indicate that the probability of the health promotion intervention being cost-effective does not exceed 0.4 for willingness to pay thresholds ranging from £0-£50,000. CONCLUSIONS: Alongside no evidence of additional quality of life/clinical benefit, there is also no evidence of cost-effectiveness. TRIAL REGISTRATION: ISRCTN58667926 .

BACKGROUND: People with psychosis have a reduced life expectancy of 10-20 years, largely due to cardiovascular disease. This trial aimed to determine the effectiveness of a modular health promotion intervention (IMPaCT Therapy) in improving health and reducing cardiovascular risk in psychosis. METHODS: A multicentre, two arm, parallel cluster RCT was conducted across five UK mental health NHS trusts. Community care coordinators (CC) were randomly assigned to training and supervision in delivering IMPaCT Therapy or treatment as usual (TAU) to current patients with psychosis (cluster). The primary outcome was the physical and mental health subscales of the Short form-36 (SF-36) questionnaire. RESULTS: Of 104 care coordinators recruited, 52 (with 213 patients) were randomised to deliver IMPaCT therapy and 52 (with 193 patients) randomised to TAU. Of 406 patients, 318 (78%) and 301 (74%) attended 12- and 15-month follow-up respectively. IMPaCT therapy showed no significant effect on the physical or mental health component SF-36 scores versus TAU at 12 or 15 months. No effect was observed for cardiovascular risk indicators, except for HDL cholesterol, which improved more with IMPACT therapy than TAU (Treatment effect (95% CI); 0.085 (0.007 to 0.16); p = 0.034). The 22% of patients who received >180 min of IMPACT Therapy in addition to usual care achieved a greater reduction in waist circumference than did controls, which was clinically significant. CONCLUSION: Training and supervising community care coordinators to use IMPaCT therapy in patients with psychosis is insufficient to significantly improve physical or mental health quality of life. The search for effective, pragmatic interventions deliverable in health care services continues. TRIAL REGISTRATION: The trial was retrospectively registered with ISRCTN registry on 23/4/2010 at ISRCTN58667926 ; recruitment started on 01/03/2010 with first randomization on 09.08.2010 ISRCTN58667926 .

BACKGROUND: Excess mortality among people with severe mental illness (SMI) is largely attributed to co-morbid physical illness. Improving the physical health of this population is critically important; however, physical health monitoring among people with SMI is often inadequate. AIMS: This study aimed to facilitate an enhanced understanding of barriers to successfully attend to clients' physical health in mental health settings, through exploring care coordinators' views and experiences regarding their ability to monitor physical health in clients with SMI (specifically, psychosis). METHODS: Semi-structured interviews were conducted with seven care coordinators from a South East London (UK) community mental health team. Data were analysed using thematic analysis principles. RESULTS: Three themes were identified in these data, capturing (1) how care coordinators viewed the professional roles of other clinical staff and themselves, (2) views on barriers to the provision of physical healthcare and (3) factors that motivated care coordinators to attend to clients' physical health. CONCLUSION: Our findings can inform efforts to implement physical healthcare interventions within mental health settings. Such insights are timely, as academic literature and guidelines regarding clinical practice increasingly promote the value of integrated provision of mental and physical healthcare.
