RESUMO

BACKGROUND: Arts-based methodologies and methods (ABM) can elicit rich and meaningful data with seldom-heard groups and empower participants in research. Young people with complex psychosocial needs could be better engaged in research using arts-based approaches to overcome communication and literacy issues as well as distrust of those with power, including researchers. A critical review of the use and impact of ABM among this population is timely. The purpose of this review is to synthesize and examine the experience and use of ABM with young people with complex psychosocial needs. METHODS: A systematic narrative literature review was conducted with a search of the literature from 2009 to 2021. All abstracts were reviewed independently by two authors and full papers were screened for eligibility against inclusion and exclusion criteria. Data synthesis focused on a descriptive numerical summary and a thematic analysis focused on key patterns across papers relating to the review objectives. RESULTS AND DISCUSSION: A total of 25 papers were included. The most common issues of focus were mental health (n = 10) and homelessness (n = 11) and methods using Photovoice (n = 12) and Body Mapping (n = 5). Individual interview data (n = 20) were the most commonly analysed, followed by created works (n = 19). Less than half the studies involved young people in the interpretation of the data collected. Knowledge translation was not described in almost half the studies, with public exhibits (n = 7) and forums with service providers (n = 4) being the most common activities. Key themes across the studies were valued over traditional methods in eliciting data, ABM as an approach to engage these young people in research and the impact of the use of ABM on participants and on key stakeholders through knowledge translation. CONCLUSIONS: The growing field of ABM presents opportunities to enhance research with young people with complex psychosocial needs by promoting meaningful exploration of experiences, engaging participants in research and strengthening knowledge translation. The involvement of young people in the interpretation of data and ensuring that knowledge translation occurs are key areas for future attention. PATIENT OR PUBLIC CONTRIBUTION: The findings of this review will inform future research to improve the engagement of young people with complex psychosocial needs in research and promote power sharing between researchers and research participants.

RESUMO

Working in Africa provides neuroscientists with opportunities that are not available in other continents. Populations in this region exhibit the greatest genetic diversity; they live in ecosystems with diverse flora and fauna; and they face unique stresses to brain health, including child brain health and development, due to high levels of traumatic brain injury and diseases endemic to the region. However, the neuroscience community in Africa has yet to reach its full potential. In this article we report the outcomes from a series of meetings at which the African neuroscience community came together to identify barriers and opportunities, and to discuss ways forward. This exercise resulted in the identification of six domains of distinction in African neuroscience: the diverse DNA of African populations; diverse flora, fauna and ecosystems for comparative research; child brain health and development; the impact of climate change on mental and neurological health; access to clinical populations with important conditions less prevalent in the global North; and resourcefulness in the reuse and adaption of existing technologies and resources to answer new questions. The article also outlines plans to advance the field of neuroscience in Africa in order to unlock the potential of African neuroscientists to address regional and global mental health and neurological problems.

RESUMO

OBJECTIVES: This study aimed to describe mental health emergency department (ED) presentations among young people aged 8-26 years in New South Wales, Australia, and to identify key characteristics associated with higher risk of ED mental health re-presentation. DESIGN, SETTING AND PARTICIPANTS: Retrospective analysis of linked ED data records for mental health presentations between 1 January 2015 and 30 June 2018. MAIN OUTCOME MEASURES: The main outcome was the total number of mental health ED re-presentations within 1 year, following initial presentation. Count regression models were fitted to estimate factors associated with higher likelihood of re-presentations. RESULTS: Forty thousand two hundred and ninety patients were included in the analyses, and 9713 (~25%) re-presented during the following year; 1831 (20%) presented at least three times. On average, patients re-presented 0.61 times per 365 person-days, with average time until first re-presentation of ~92 days but greatest risk of re-presentation within first 30-60 days. Young people with self-harm or suicidal diagnoses at initial presentation were more likely to re-present. Re-presentations were highest among young people <15 years (IRR 1.18 vs ≥20 years old), female (IRR=1.13 vs male), young people residing outside of major cities (IRR 1.08 vs major cities) and Aboriginal and Torres Strait Islander young people (IRR 1.27 vs non-Indigenous). CONCLUSIONS: ED mental health re-presentation is high among young people. We demonstrate factors associated with re-presentation that EDs could target for timely, high-quality care that is youth friendly and culturally safe, with appropriate referral pathways into community-based primary and mental healthcare services.

RESUMO

OBJECTIVES: Housing is a social determinant of health that impacts the health and well-being of children and families. Screening and referral to address social determinants of health in clinical and social service settings has been proposed to support families with housing problems. This study aims to identify housing screening questions asked of families in healthcare and social services, determine validated screening tools and extract information about recommendations for action after screening for housing issues. METHODS: The electronic databases MEDLINE, PsycINFO, EMBASE, Ovid Emcare, Scopus and CINAHL were searched from 2009 to 2021. Inclusion criteria were peer-reviewed literature that included questions about housing being asked of children or young people aged 0-18 years and their families accessing any healthcare or social service. We extracted data on the housing questions asked, source of housing questions, validity and descriptions of actions to address housing issues. RESULTS: Forty-nine peer-reviewed papers met the inclusion criteria. The housing questions in social screening tools vary widely. There are no standard housing-related questions that clinical and social service providers ask families. Fourteen screening tools were validated. An action was embedded as part of social screening activities in 27 of 42 studies. Actions for identified housing problems included provision of a community-based or clinic-based resource guide, and social prescribing included referral to a social worker, care coordinator or care navigation service, community health worker, social service agency, referral to a housing and child welfare demonstration project or provided intensive case management and wraparound services. CONCLUSION: This review provides a catalogue of housing questions that can be asked of families in the clinical and/or social service setting, and potential subsequent actions.

RESUMO

Women experience persistent pain at higher rates than men; however, women are less likely to be provided with adequate or appropriate care and more likely to have their pain experiences dismissed. The purpose of this review is to consider the complex interaction of the biopsychosocial factors in the experience of persistent pain in order to inform improved models of care. Given persistent pain is among the most frequently reported health consequences of intimate partner violence (IPV), this review focused on studies exploring the association between persistent pain and IPV. Three reviewers independently and systematically searched seven databases. Qualitative and quantitative studies describing the association between IPV and persistent pain published between January 2000 and June 2018 were included. Twelve studies met the inclusion criteria. The included studies demonstrated that a history of IPV places an additional burden on women who experience persistent pain that cannot be explained by an underlying psychological condition. Health care practitioners should be aware of this phenomena to ensure diagnosis, assessment, and treatment plans are targeted accordingly. Future policy directives and research should account for and seek to elucidate this additional burden.

RESUMO

It is imperative that access to primary health care services is equitable as health care practitioners are often the first responders to women who experience violence. This is of particular importance for First Nations women who disproportionately experience interpersonal and structural violence when compared to non-First Nations women, as well as the ongoing impact of colonization, racism, and intergenerational trauma. To understand how primary health care services can provide equitable and effective care for First Nations women, we explored how trauma and violence informed care is integrated in primary health care settings through the lens of an equity-oriented framework. A systematic search of electronic databases included Medline (via Ovid), Scopus, Informit, and PubMed and grey literature. Six studies were included in the review and we undertook a narrative synthesis using the equity-oriented framework to draw together the intersection of trauma and violence informed care with culturally safe and contextually tailored care. This review demonstrates how equity-oriented primary health care settings respond to the complex and multiple forms of violence and intergenerational trauma experienced by First Nations women and thus mitigate shame and stigma to encourage disclosure and help seeking. Key attributes include responding to women's individual contexts by centering family, engaging elders, encouraging community ownership, which is driven by a culturally competent workforce that builds trust, reduces retraumatization, and respects confidentiality. This review highlights the importance of strengthening and supporting the workforce, as well as embedding cultural safety within intersectoral partnerships and ensuring adequate resourcing and sustainability of initiatives.

RESUMO

OBJECTIVE: Young people (10-24 years old) with mental health concerns are increasingly presenting to hospital emergency departments (EDs). The purpose of this review was to identify the core components and outcomes of mental health interventions for young people that are initiated in the ED, such that they are delivered in the ED and/or by ED health workers. METHODS: Six electronic databases were systematically searched. Primary peer-reviewed qualitative or quantitative studies describing an ED-initiated mental health intervention for young people published between 2009 and 2020 were included. RESULTS: Nine studies met the inclusion criteria. The included studies demonstrated that compared with traditional ED care, ED-initiated mental health interventions lead to improved efficiency of care and decreased length of stay, and a core component of this care was its delivery by allied health practitioners with mental health expertise. The studies were limited by focusing on service efficiencies rather than patient outcomes. Further limitations were the exclusion of young people with complex mental health needs and/or comorbidities and not measuring long-term positive mental health outcomes, including representations and whether young people were connected with community health services. CONCLUSIONS: This systematic review demonstrated that ED-initiated mental health interventions result in improved service outcomes, but further innovation and robust evaluation are required. Future research should determine whether these interventions lead to better clinical outcomes for young people and staff to inform the development of best practice recommendations for ED-initiated mental health care for young people presenting to the ED.

RESUMO

ISSUE ADDRESSED: It is demonstrated that primary health care (PHC) providers are sought out by women who experience violence. Given the disproportionate burden of violence experienced by Aboriginal and Torres Strait Islander women, it is essential there is equitable access to appropriate PHC services. This review aimed to analyse whether Australian PHC policy accounts for the complex needs of Aboriginal and Torres Strait Islander women experiencing violence and the importance of PHC providers responding to violence in culturally safe ways. METHODS: Using the Arskey and O'Malley framework, an iterative scoping review determined the policies for analysis. The selected policies were analysed against concepts identified as key components in responding to the needs of Aboriginal and Torres Strait Islander women experiencing violence. The key components are Family Violence, Violence against Aboriginal and Torres Strait Islander Women, Social Determinants of Aboriginal and Torres Strait Islander Health and Wellbeing, Cultural Safety, Holistic Health, Trauma, Patient-Centred Care and Trauma-and-Violence-Informed Care. RESULTS: Following a search of Australian government websites, seven policies were selected for analysis. Principally, no policy embedded or described best practice across all key components. CONCLUSION: The review demonstrates the need for a specific National framework supporting Aboriginal and Torres Strait Islander women who seek support from PHC services, as well as further policy analysis and review. SO WHAT?: Aboriginal and Torres Strait Islander women disproportionately experience more severe violence, with complex impact, than other Australian women. PHC policy and practice frameworks must account for this, together with the intersection of contemporary manifestations of colonialism and historical and intergenerational trauma.

RESUMO

INTRODUCTION: The placenta controls nutrient transfer between mother and fetus via membrane transporters. Appropriate transplacental passage of nutrients is essential for fetal growth and development. We investigated whether transporter transcript levels in human placenta-liver pairs from first and early second trimester pregnancies exhibit gestational age- or fetal sex-specific profiles and whether these are dysregulated by maternal smoking. METHODS: In a step-change for the field, paired placenta and fetal livers from 54 electively terminated, normally-progressing pregnancies (7-20 weeks of gestation, Scottish Advanced Fetal Research Study, REC 15/NS/0123) were sexed and cigarette smoking-exposure confirmed. Thirty-six nutrient transporter transcripts were quantified using RT-qPCR. RESULTS: While fetal, liver and placenta weights were not altered by maternal smoking, levels of transporter transcripts changed with fetal age and sex in the placenta and fetal liver and their trajectories were altered if the mother smoked. Placental levels of glucose uptake transporters SLC2A1 and SLC2A3 increased in smoking-exposed fetuses while smoking was associated with altered levels of amino acid and fatty acid transporter genes in both tissues. SLC7A8, which exchanges non-essential amino acids in the fetus for essential amino acids from the placenta, was reduced in smoking-exposed placentas while transcript levels of four hepatic fatty acid uptake transporters were also reduced by smoking. DISCUSSION: This data shows that fetal sex and age and maternal smoking are associated with altered transporter transcript levels. This could influence nutrient transport across the placenta and subsequent uptake by the fetal liver, altering trophic delivery to the growing fetus.

RESUMO

Masculinization of the external genitalia in humans is dependent on formation of 5α-dihydrotestosterone (DHT) through both the canonical androgenic pathway and an alternative (backdoor) pathway. The fetal testes are essential for canonical androgen production, but little is known about the synthesis of backdoor androgens, despite their known critical role in masculinization. In this study, we have measured plasma and tissue levels of endogenous steroids in second trimester human fetuses using multidimensional and high-resolution mass spectrometry. Results show that androsterone is the principal backdoor androgen in the male fetal circulation and that DHT is undetectable (<1 ng/mL), while in female fetuses, there are significantly lower levels of androsterone and testosterone. In the male, intermediates in the backdoor pathway are found primarily in the placenta and fetal liver, with significant androsterone levels also in the fetal adrenal. Backdoor intermediates, including androsterone, are only present at very low levels in the fetal testes. This is consistent with transcript levels of enzymes involved in the alternate pathway (steroid 5α-reductase type 1 [SRD5A1], aldo-keto reductase type 1C2 [AKR1C2], aldo-keto reductase type 1C4 [AKR1C4], cytochrome P450 17A1 [CYP17A1]), as measured by quantitative PCR (qPCR). These data identify androsterone as the predominant backdoor androgen in the human fetus and show that circulating levels are sex dependent, but also that there is little de novo synthesis in the testis. Instead, the data indicate that placental progesterone acts as substrate for synthesis of backdoor androgens, which occurs across several tissues. Masculinization of the human fetus depends, therefore, on testosterone and androsterone synthesis by both the fetal testes and nongonadal tissues, leading to DHT formation at the genital tubercle. Our findings also provide a solid basis to explain why placental insufficiency is associated with disorders of sex development in humans.

RESUMO

BACKGROUND: The increased incidence of diseases, including metabolic syndrome and infertility, may be related to exposure to the mixture of chemicals, which are ubiquitous in the modern environment (environmental chemicals, ECs). Xeno-detoxification occurs within the liver which is also the source of many plasma proteins and growth factors and plays an important role in the regulation of homeostasis. OBJECTIVES: The objective of this study was to investigate the effects of ECs on aspects of liver function, in a well characterized ovine model of exposure to a real-life EC mixture. METHODS: Four groups of sheep (n = 10-12/sex/treatment) were maintained long-term on control or sewage sludge-fertilized pastures: from conception to culling at 19 months of age in females and from conception to 7 months of age and thereafter in control plots until culling at 19 months of age in males. Environmental chemicals were measured in sheep livers and RNA and protein extracts were assessed for exposure markers. Liver proteins were resolved using 2D differential in-gel electrophoresis and differentially expressed protein spots were identified by liquid chromatography/tandem mass spectroscopy. RESULTS: Higher levels of polycyclic aromatic hydrocarbons (PAHs) and lower levels of polychlorinated biphenyls (PCBs) in the livers of control males compared to control females indicated sexually dimorphic EC body burdens. Increased levels of the PAHs Benzo[a]anthracene and chrysene and reduced levels of PCB 153 and PCB 180 were observed in the livers of continuously exposed females. EC exposure affected xenobiotic and detoxification responses and the liver proteome in both sexes and included major plasma-secreted and blood proteins, and metabolic enzymes whose pathway analysis predicted dysregulation of cancer-related pathways and altered lipid dynamics. The latter were confirmed by a reduction in total lipids in female livers and up-regulation of cancer-related transcript markers in male livers respectively by sewage sludge exposure. CONCLUSIONS: Our results demonstrate that chronic exposure to ECs causes major physiological changes in the liver, likely to affect multiple systems in the body and which may predispose individuals to increased disease risks.

RESUMO

The placenta is a critical organ during pregnancy, essential for the provision of an optimal intrauterine environment, with fetal survival, growth, and development relying on correct placental function. It must allow nutritional compounds and relevant hormones to pass into the fetal bloodstream and metabolic waste products to be cleared. It also acts as a semipermeable barrier to potentially harmful chemicals, both endogenous and exogenous. Transporter proteins allow for bidirectional transport and are found in the syncytiotrophoblast of the placenta and endothelium of fetal capillaries. The major transporter families in the human placenta are ATP-binding cassette (ABC) and solute carrier (SLC), and insufficiency of these transporters may lead to deleterious effects on the fetus. Transporter expression levels are gestation-dependent and this is of considerable clinical interest as levels of drug resistance may be altered from one trimester to the next. This highlights the importance of these transporters in mediating correct and timely transplacental passage of essential compounds but also for efflux of potentially toxic drugs and xenobiotics. We review the current literature on placental molecular transporters with respect to their localization and ontogeny, the influence of fetal sex, and the relevance of animal models. We conclude that a paucity of information exists, and further studies are required to unlock the enigma of this dynamic organ.

RESUMO

A subset of ultraluminous X-ray sources (those with luminosities of less than 10(40) erg s(-1); ref. 1) are thought to be powered by the accretion of gas onto black holes with masses of ∼5-20M cicled dot, probably by means of an accretion disk. The X-ray and radio emission are coupled in such Galactic sources; the radio emission originates in a relativistic jet thought to be launched from the innermost regions near the black hole, with the most powerful emission occurring when the rate of infalling matter approaches a theoretical maximum (the Eddington limit). Only four such maximal sources are known in the Milky Way, and the absorption of soft X-rays in the interstellar medium hinders the determination of the causal sequence of events that leads to the ejection of the jet. Here we report radio and X-ray observations of a bright new X-ray source in the nearby galaxy M 31, whose peak luminosity exceeded 10(39) erg s(-1). The radio luminosity is extremely high and shows variability on a timescale of tens of minutes, arguing that the source is highly compact and powered by accretion close to the Eddington limit onto a black hole of stellar mass. Continued radio and X-ray monitoring of such sources should reveal the causal relationship between the accretion flow and the powerful jet emission.
