RESUMO

Psychiatry has increasingly adopted explanations for psychopathology that are based on neurobiological reductionism. With the recognition of health disparities and the realisation that someone's postcode can be a better predictor of health outcomes than their genetic code, there are increasing efforts to ensure cultural and social-structural competence in psychiatric practice. Although neuroscientific and social-cultural approaches in psychiatry remain largely separate, they can be brought together in a multilevel explanatory framework to advance psychiatric theory, research, and practice. In this Personal View, we outline how a cultural-ecosocial systems approach to integrating neuroscience in psychiatry can promote social-contextual and systemic thinking for more clinically useful formulations and person-centred care.

RESUMO

Targeting modifiable risk factors may help to prevent Alzheimer's disease (AD), but the pathways by which these risk factors influence AD risk remain incompletely understood. We identified genome-wide association studies for AD and its major modifiable risk factors. We calculated the genetic correlation among these traits and modelled this using genomic structural equation modelling. We identified complex networks of genetic overlap among AD risk factors, but AD itself was largely genetically distinct. The data were best explained by a bi-factor model, incorporating a Common Factor for AD risk, and 3 orthogonal sub-clusters of risk factors. Taken together, our findings suggest that there is extensive shared genetic architecture between AD modifiable risk factors, but this is largely independent of AD genetic pathways. Extensive genetic pleiotropy between risk factors may influence AD indirectly by decreasing cognitive reserve or increasing risk of multimorbidity, leading to poorer brain health. Further work to understand the biology reflected by this communality may provide novel mechanistic insights that could help to prioritise targets for dementia prevention.

RESUMO

BACKGROUND: There is no Kenyan evidence on the relationship between mental illness and academic performance. We aimed to determine the effect of life skills training on mental health and academic performance. METHODS: We administered to 1848 primary school children a researcher designed socio-demographic questionnaire, and the Youth Self Report (YSR) and Child Behavior Checklist (CBCL) to their parents, followed by eight sessions of life skills training. We extracted data from the individual records of each child on overall performance pre and post training separated by one year. We conducted descriptive statistics, paired sample t-tests, multivariate linear regression analysis and linear mixed model analysis to assess changing patterns of academic performance and any predictive characteristics. RESULTS: There was significant (p < 0.05) improvement in overall academic performance (aggregate marks and all individual subjects) for both lower primary and upper primary classes after the life-skills training intervention. For lower classes (2-4 grades) increase in academic performance was significantly associated with fathers and mothers education levels, region and class. For upper classes, (5-7 grades) increase in academic performance was associated with region, class and age. CONCLUSIONS: Life skills training is recommended as it could improve academic performance, but predicted by socio-demographic factors.

RESUMO

The COVID-19 pandemic has stunned the global community with marked social and psychological ramifications. There are key challenges for psychiatry that require urgent attention to ensure mental health well-being for all - COVID-19-positive patients, healthcare professionals, first responders, people with psychiatric disorders and the general population. This editorial outlines some of these challenges and research questions, and serves as a preliminary framework of what needs to be addressed. Mental healthcare should be an integral component of healthcare policy and practice towards COVID-19. Collaborative efforts from psychiatric organisations and their members are required to maximise appropriate clinical and educational interventions while minimising stigma.

RESUMO

Cultural diversity poses a challenge to mental Health care systems in many settings. Specialized cultural consultation services have been developed in a number of countries as a way to supplement existing services. The objective of this paper is to compare and contrast cultural consultation services in Montreal, London, and Paris to determine how culture and society have shaped the evolution of these services to meet local sensitivities and imperatives. Historical contexts of the sites, their descriptions and origins, how they categorize cultural, ethnic, and linguistic diversity, and their intake procedures are compared and contrasted according to a standardized template of themes. Data came from site visits and participant observation at each site. For historical, political, and cultural reasons, categorization of diversity and intake procedures differ markedly by site: Montreal focuses on language categories and language proficiency; London enumerates ethnic diversity according to officially mandated categories; and Paris does not gather ethnic data on its patients in any form. The process of cultural consultation, specifically its triage and intake procedures, is profoundly influenced by local histories and social norms that are maintained by professional cultures of psychiatry in each setting. To properly place their patients in context, cultural psychiatrists must not only aim to understand the culture of the other, but also must consider the culture of the mainstream society and how it shapes the delivery of services.

RESUMO

In this article we use the example of race/ethnic inequalities in severe mental illness to demonstrate the utility of a novel integrative approach to theorising the role of racism in generating inequality. Ethnic minority people in the UK are at much greater risk than White British people of being diagnosed with a severe - psychosis related - mental illness, and this is particularly the case for those with Black Caribbean or Black African origins. There is entrenched dispute about how we might understand the drivers of this inequality. To address this dispute we build on, and to a certain extent refine, established approaches to theorising structural and institutional racism, and integrate this within a theoretical framework that also incorporates racist/discriminatory interactions (interpersonal racism). We argue that this provides a conceptually robust and thorough analysis of the role of inter-related dimensions of racism in shaping risks of severe mental illness, access to care, and policy and practice responses. This analysis carries implications for a broader, but integrated, understanding of the fundamental drives of race/ethnic inequalities in health and for an anti-racism public health agenda.

RESUMO

Addictions are challenging health and social problems that need to be addressed to preserve and promote good mental health and ensure that individuals within society lead healthy and productive lives. Tackling addictions is complex and requires communities, public health, specialist services, and local and national government to act in unison and implement evidence-based interventions. This editorial raises systemic issues that need attention and proposes a range of systemic options.

RESUMO

The concepts of allostatic load and overload, i. e., a dramatic increase in the allostatic load that predisposes to disease, have been extensively described in the literature. Here, we show that rats engaging in active offensive response (AOR) behavioral strategies to chronic predator scent stress (PSS) display less anxiety behavior and lower plasma cortisol levels vs. rats engaging in passive defensive response (PDR) behavioral strategies to chronic PSS. In the same chronic PSS paradigm, AOR rats also have higher lactate and lower glutamate levels in amygdala but not in control-region hippocampus vs. PDR rats. The implications of these findings for regulation of allostatic and stress responses, and post-traumatic stress disorder (PTSD) are discussed.

RESUMO

Schizophrenia and anorexia nervosa were recently added to the list of conditions for which whole genome sequencing might be indicated as part of the 100 000 Genomes Project, reflecting the remarkable recent progress in findings emerging from psychiatric genetics research. Genetic testing methods may offer increased opportunities for diagnosis and estimation of familial risk and could have implications for management and treatment options. They also present ethical and philosophical questions about the role of testing and storage of genetic information. Mental health professionals will need to have a good understanding of this area in order for patients to fully realise the benefits of these advances.Declaration of InterestK.S.B. is Editor of the British Journal of Psychiatry.

RESUMO

BACKGROUND: In the Global Burden of Disease Study 2013 (GBD 2013), knowledge about health and its determinants has been integrated into a comparable framework to inform health policy. Outputs of this analysis are relevant to current policy questions in England and elsewhere, particularly on health inequalities. We use GBD 2013 data on mortality and causes of death, and disease and injury incidence and prevalence to analyse the burden of disease and injury in England as a whole, in English regions, and within each English region by deprivation quintile. We also assess disease and injury burden in England attributable to potentially preventable risk factors. England and the English regions are compared with the remaining constituent countries of the UK and with comparable countries in the European Union (EU) and beyond. METHODS: We extracted data from the GBD 2013 to compare mortality, causes of death, years of life lost (YLLs), years lived with a disability (YLDs), and disability-adjusted life-years (DALYs) in England, the UK, and 18 other countries (the first 15 EU members [apart from the UK] and Australia, Canada, Norway, and the USA [EU15+]). We extended elements of the analysis to English regions, and subregional areas defined by deprivation quintile (deprivation areas). We used data split by the nine English regions (corresponding to the European boundaries of the Nomenclature for Territorial Statistics level 1 [NUTS 1] regions), and by quintile groups within each English region according to deprivation, thereby making 45 regional deprivation areas. Deprivation quintiles were defined by area of residence ranked at national level by Index of Multiple Deprivation score, 2010. Burden due to various risk factors is described for England using new GBD methodology to estimate independent and overlapping attributable risk for five tiers of behavioural, metabolic, and environmental risk factors. We present results for 306 causes and 2337 sequelae, and 79 risks or risk clusters. FINDINGS: Between 1990 and 2013, life expectancy from birth in England increased by 5·4 years (95% uncertainty interval 5·0-5·8) from 75·9 years (75·9-76·0) to 81·3 years (80·9-81·7); gains were greater for men than for women. Rates of age-standardised YLLs reduced by 41·1% (38·3-43·6), whereas DALYs were reduced by 23·8% (20·9-27·1), and YLDs by 1·4% (0·1-2·8). For these measures, England ranked better than the UK and the EU15+ means. Between 1990 and 2013, the range in life expectancy among 45 regional deprivation areas remained 8·2 years for men and decreased from 7·2 years in 1990 to 6·9 years in 2013 for women. In 2013, the leading cause of YLLs was ischaemic heart disease, and the leading cause of DALYs was low back and neck pain. Known risk factors accounted for 39·6% (37·7-41·7) of DALYs; leading behavioural risk factors were suboptimal diet (10·8% [9·1-12·7]) and tobacco (10·7% [9·4-12·0]). INTERPRETATION: Health in England is improving although substantial opportunities exist for further reductions in the burden of preventable disease. The gap in mortality rates between men and women has reduced, but marked health inequalities between the least deprived and most deprived areas remain. Declines in mortality have not been matched by similar declines in morbidity, resulting in people living longer with diseases. Health policies must therefore address the causes of ill health as well as those of premature mortality. Systematic action locally and nationally is needed to reduce risk exposures, support healthy behaviours, alleviate the severity of chronic disabling disorders, and mitigate the effects of socioeconomic deprivation.

RESUMO

BACKGROUND: Communication may be an influential determinant of inequality of access to, engagement with and benefit from psychiatric services. AIMS: To review the evidence on interventions designed to improve therapeutic communications between Black and minority ethnic patients and clinicians who provide care in psychiatric services. METHOD: Systematic review and evidence synthesis (PROSPERO registration: CRD42011001661). Data sources included the published and the 'grey' literature. A survey of experts and a consultation with patients and carers all contributed to the evidence synthesis, interpretation and recommendations. RESULTS: Twenty-one studies were included in our analysis. The trials showed benefits mainly for depressive symptoms, experiences of care, knowledge, stigma, adherence to prescribed medication, insight and alliance. The effect sizes were smaller for better-quality trials (range of d 0.18-0.75) than for moderate- or lower-quality studies (range of d 0.18-4.3). The review found only two studies offering weak economic evidence. CONCLUSIONS: Culturally adapted psychotherapies, and ethnographic and motivational assessment leading to psychotherapies were effective and favoured by patients and carers. Further trials are needed from outside of the UK and USA, as are economic evaluations and studies of routine psychiatric care practices.

RESUMO

BACKGROUND: Hepatitis B and C (HBV, HCV) infections are associated with high morbidity and mortality. Many countries with traditionally low prevalence (such as UK) are now planning interventions (screening, vaccination, and treatment) of high-risk immigrants from countries with high prevalence. This review aimed to synthesise the evidence on immigrants' knowledge of HBV and HCV that might influence the uptake of clinical interventions. The review was also used to inform the design and successful delivery of a randomised controlled trial of targeted screening and treatment. METHODS: Five databases (PubMed, CINHAL, SOCIOFILE, PsycINFO & Web of Science) were systematically searched, supplemented by reference tracking, searches of selected journals, and of relevant websites. We aimed to identify qualitative and quantitative studies that investigated knowledge of HBV and HCV among immigrants from high endemic areas to low endemic areas. Evidence, extracted according to a conceptual framework of Kleinman's explanatory model, was subjected to narrative synthesis. We adapted the PEN-3 model to categorise and analyse themes, and recommend strategies for interventions to influence help-seeking behaviour. RESULTS: We identified 51 publications including quantitative (n = 39), qualitative (n = 11), and mixed methods (n = 1) designs. Most of the quantitative studies included small samples and had heterogeneous methods and outcomes. The studies mainly concentrated on hepatitis B and ethnic groups of South East Asian immigrants residing in USA, Canada, and Australia. Many immigrants lacked adequate knowledge of aetiology, symptoms, transmission risk factors, prevention strategies, and treatment, of hepatitis HBV and HCV. Ethnicity, gender, better education, higher income, and English proficiency influenced variations in levels and forms of knowledge. CONCLUSION: Immigrants are vulnerable to HBV and HCV, and risk life-threatening complications from these infections because of poor knowledge and help-seeking behaviour. Primary studies in this area are extremely diverse and of variable quality precluding meta-analysis. Further research is needed outside North America and Australia.

RESUMO

This paper reports on a feasibility study and evaluation of a new type of cultural consultation service (CCS). This multi-component and systemic complex intervention was offered over 18 months to specialist mental health providers in one of the poorest regions of the UK. The service received 900 clinically related contacts and 99 in-depth consultations. Service users who were referred to the CCS had high levels of clinical needs with an average score of 15.9 on the Health of the Nation Outcomes Scale. Overall, Global Assessment of Function scores improved and there were trends for improvements in symptoms. The level of routine care (and by implication associated costs) significantly reduced after CCS intervention, due to a reduction in use of accident and emergency (A&E) services, psychiatrists and community psychiatric nurses (CPNs)/case managers. Cost analysis indicates that savings amounted to £497 per patient. The cost of intervention was no greater than usual care, and may reduce spend per patient over a 3-month follow-up and perhaps longer. More specifically, clinicians felt the cultural consultation service helped to improve the treatment plan (71%), engagement (50%), medication compliance (21%) and earlier discharge (7%).
