'Y Health - Staying Deadly' : an Aboriginal youth focussed translational action research project

Aboriginal & Torres Strait Islander youth are at-risk health consumers, being over-represented in social and health disadvantage and under-represented as seekers of health care. Young people have very different developmental and health needs and causes of illness compared to children or adults. Adolescence is also a period of risk taking and experimentation which has potential for serious adverse health outcomes. In addition, young people are future parents; health promotion activities in this group have the potential for impacting on the next generation. Through the Medicare Benefits Schedule (MBS), Aboriginal & Torres Strait Islander Health Checks have been in place to ensure that primary health care is matched to needs, by identifying and addressing problems at an early stage. The current MBS Item 715 (Health Check) covers children (0 - 14 yrs), adults (15 - 54 yrs) and older persons (>55 yrs). All of these categories are unsatisfactory in their ability to address youth health needs. Furthermore, though there is some research available regarding youth assessment, there is no comprehensive health screening tool available for Aboriginal youth. Using a Community Based Participatory and Translational Action Research approach, this project has developed and implemented an evidence informed, culturally valid, strengths based and user friendly Youth Health Check and accompanying Youth Health Audit tool.The research reported in this paper is a project of the Australian Primary Health Care Research Institute which is supported by a grant from the Australian Government Department of Health and Ageing under the Primary Health Care Research Evaluation and Development Strategy

Targeted prevention of common mental health disorders in university students: randomised controlled trial of a transdiagnostic trait-focused web-based intervention

Background: A large proportion of university students show symptoms of common mental disorders, such as depression, anxiety, substance use disorders and eating disorders. Novel interventions are required that target underlying factors of multiple disorders.<p></p> Aims: To evaluate the efficacy of a transdiagnostic trait-focused web-based intervention aimed at reducing symptoms of common mental disorders in university students.<p></p> Method: Students were recruited online (n = 1047, age: M = 21.8, SD = 4.2) and categorised into being at high or low risk for mental disorders based on their personality traits. Participants were allocated to a cognitive-behavioural trait-focused (n = 519) or a control intervention (n = 528) using computerised simple randomisation. Both interventions were fully automated and delivered online (trial registration: ISRCTN14342225). Participants were blinded and outcomes were self-assessed at baseline, at 6 weeks and at 12 weeks after registration. Primary outcomes were current depression and anxiety, assessed on the Patient Health Questionnaire (PHQ9) and Generalised Anxiety Disorder Scale (GAD7). Secondary outcome measures focused on alcohol use, disordered eating, and other outcomes.<p></p> Results: Students at high risk were successfully identified using personality indicators and reported poorer mental health. A total of 520 students completed the 6-week follow-up and 401 students completed the 12-week follow-up. Attrition was high across intervention groups, but comparable to other web-based interventions. Mixed effects analyses revealed that at 12-week follow up the trait-focused intervention reduced depression scores by 3.58 (p<.001, 95%CI [5.19, 1.98]) and anxiety scores by 2.87 (p = .018, 95%CI [1.31, 4.43]) in students at high risk. In high-risk students, between group effect sizes were 0.58 (depression) and 0.42 (anxiety). In addition, self-esteem was improved. No changes were observed regarding the use of alcohol or disordered eating.<p></p> Conclusions This study suggests that a transdiagnostic web-based intervention for university students targeting underlying personality risk factors may be a promising way of preventing common mental disorders with a low-intensity intervention

Declaração de consenso da seção de psiquiatria geriátrica da Associação Mundial de Psiquiatria sobre ética e capacidade em pessoas idosas com doença mental

BACKGROUND: The World Psychiatric Association (WPA) Section of Old Age Psychiatry, since 1997, has developed Consensus Statements relevant to the practice of Old Age Psychiatry. Since 2006 the Section has worked to develop a Consensus Statement on Ethics and Capacity in older people with mental disorders. METHOD: A Consensus Conference was realized in Prague, September 2008. The meeting was organized by the WPA Section of Old Age Psychiatry, with the participation of International Council of Nurses, Alzheimer Europe and Alzheimer Disease International. Participants who are recognised for their expertise in this area came from 11 countries and include psychiatrists, a neurologist, a nurse and family caregiving representatives. RESULTS: After two days of debate a draft was prepared and submitted to the organizations/associations represented at the meeting. When their respective comments were collected, a final text was prepared and published originally in English. This Portuguese version was prepared by two members of the meeting who came from Portuguese spoken countries. DISCUSSION: This Consensus Statement offers to mental health clinicians caring for older people with mental disorders, caregivers, other health professionals and the general public the setting out of and discourse in ethical principles which can often be complex and challenging, supported by practical guidance in meeting such ethical needs and standards, and to encouraged good clinical practice.CONTEXTO: A Seção de Psiquiatria Geriátrica da Associação Mundial de Psiquiatria (AMP), desde 1997, vem desenvolvendo Declarações de Consenso relevantespara a prática da Psiquiatria Geriátrica.

CONCLUSÕES: Essa Declaração de Consenso oferece aos clínicos em saúde mental que cuidam de pessoas idosas com transtornos mentais, cuidadores, outros profissionais da saúde e o público em geral as definições e o debate sobre os princípios éticos que podem frequentemente ser complexos e desafiadores, apoiados em orientações práticas para satisfazer tais necessidades e padrões éticos e encorajar a boa prática clínica

Redução da estigmatização e da discriminação das pessoas idosas com transtornos mentais: uma declaração técnica de consenso

This technical consensus statement is jointly produced by the Old Age Psychiatry section of the World Psychiatric Association and the World Health Organization, with the collaboration of several NGOs and the participation of experts from different regions. It is intended to be a tool for (i) promoting debate at all levels on the stigmatization of older people with mental disorders; (ii) outlining the nature, causes and consequences of this stigmatization; and (iii) promoting and suggesting policies, programs and actions to combat this stigmatization.A Organização Mundial da Saúde (OMS) e a Seção de Psiquiatria da Pessoa Idosa da Associação Mundial de Psiquiatria (AMP), em colaboração com um grupo interdisciplinar de representantes das principais associações internacionais e organizações não-governamentais implicadas na saúde mental das pessoas idosas, publicaram três declarações técnicas de consenso sobre a psiquiatria da pessoa idosa (1), a organização dos cuidados em psiquiatria da pessoa idosa (2) e o ensino da psiquiatria da pessoa idosa (3). O Dia Mundial da Saúde 2001, cujo tema foi "Não à exclusão, sim aos cuidados", deu origem a uma nova reunião de consenso sobre o tema da estigmatização e discriminação das pessoas idosas com transtornos mentais. Essa nova reunião foi realizada em Lausanne nos dias 8 e 9 de outubro de 2001 e produziu uma declaração técnica de consenso. O texto inicial foi publicado pela OMS e AMP em inglês.

Upper mantle electrical resistivity structure beneath the central Mariana subduction system

The definitive version was published in Geochemistry Geophysics Geosystems 11 (2010): Q09003, doi:10.1029/2010GC003101.This paper reports on a magnetotelluric (MT) survey across the central Mariana subduction system, providing a comprehensive electrical resistivity image of the upper mantle to address issues of mantle dynamics in the mantle wedge and beneath the slow back-arc spreading ridge. After calculation of MT response functions and their correction for topographic distortion, two-dimensional electrical resistivity structures were generated using an inversion algorithm with a smoothness constraint and with additional restrictions imposed by the subducting slab. The resultant isotropic electrical resistivity structure contains several key features. There is an uppermost resistive layer with a thickness of up to 150 km beneath the Pacific Ocean Basin, 80–100 km beneath the Mariana Trough, and 60 km beneath the Parece Vela Basin along with a conductive mantle beneath the resistive layer. A resistive region down to 60 km depth and a conductive region at greater depth are inferred beneath the volcanic arc in the mantle wedge. There is no evidence for a conductive feature beneath the back-arc spreading center. Sensitivity tests were applied to these features through inversion of synthetic data. The uppermost resistive layer is the cool, dry residual from the plate accretion process. Its thickness beneath the Pacific Ocean Basin is controlled mainly by temperature, whereas the roughly constant thickness beneath the Mariana Trough and beneath the Parece Vela Basin regardless of seafloor age is controlled by composition. The conductive mantle beneath the uppermost resistive layer requires hydration of olivine and/or melting of the mantle. The resistive region beneath the volcanic arc down to 60 km suggests that fluids such as melt or free water are not well connected or are highly three-dimensional and of limited size. In contrast, the conductive region beneath the volcanic arc below 60 km depth reflects melting and hydration driven by water release from the subducting slab. The resistive region beneath the back-arc spreading center can be explained by dry mantle with typical temperatures, suggesting that any melt present is either poorly connected or distributed discontinuously along the strike of the ridge. Evidence for electrical anisotropy in the central Mariana upper mantle is weak.Japanese participation in the Marianas experiment was supported by Japan Society for the Promotion of Science for Grant-In-Aid for Scientific Research (15340149 and 12440116), Japan-U.S. Integrated Action Program and the 21st Century COE Program of Origin and Evolution of Planetary Systems, and by the Ministry of Education, Culture, Sports, Science, and Technology for the Stagnant Slab Project, Grant-in Aid for Scientific Research on Priority Areas (17037003 and 16075204).

Comparison of mouse mammary gland imaging techniques and applications: Reflectance confocal microscopy, GFP Imaging, and ultrasound

<p>Abstract</p> <p>Background</p> <p>Genetically engineered mouse models of mammary gland cancer enable the <it>in vivo </it>study of molecular mechanisms and signaling during development and cancer pathophysiology. However, traditional whole mount and histological imaging modalities are only applicable to non-viable tissue.</p> <p>Methods</p> <p>We evaluated three techniques that can be quickly applied to living tissue for imaging normal and cancerous mammary gland: reflectance confocal microscopy, green fluorescent protein imaging, and ultrasound imaging.</p> <p>Results</p> <p>In the current study, reflectance confocal imaging offered the highest resolution and was used to optically section mammary ductal structures in the whole mammary gland. Glands remained viable in mammary gland whole organ culture when 1% acetic acid was used as a contrast agent. Our application of using green fluorescent protein expressing transgenic mice in our study allowed for whole mammary gland ductal structures imaging and enabled straightforward serial imaging of mammary gland ducts in whole organ culture to visualize the growth and differentiation process. Ultrasound imaging showed the lowest resolution. However, ultrasound was able to detect mammary preneoplastic lesions 0.2 mm in size and was used to follow cancer growth with serial imaging in living mice.</p> <p>Conclusion</p> <p>In conclusion, each technique enabled serial imaging of living mammary tissue and visualization of growth and development, quickly and with minimal tissue preparation. The use of the higher resolution reflectance confocal and green fluorescent protein imaging techniques and lower resolution ultrasound were complementary.</p

Hepatic safety of antibiotics used in primary care

Antibiotics used by general practitioners frequently appear in adverse-event reports of drug-induced hepatotoxicity. Most cases are idiosyncratic (the adverse reaction cannot be predicted from the drug's pharmacological profile or from pre-clinical toxicology tests) and occur via an immunological reaction or in response to the presence of hepatotoxic metabolites. With the exception of trovafloxacin and telithromycin (now severely restricted), hepatotoxicity crude incidence remains globally low but variable. Thus, amoxicillin/clavulanate and co-trimoxazole, as well as flucloxacillin, cause hepatotoxic reactions at rates that make them visible in general practice (cases are often isolated, may have a delayed onset, sometimes appear only after cessation of therapy and can produce an array of hepatic lesions that mirror hepatobiliary disease, making causality often difficult to establish). Conversely, hepatotoxic reactions related to macrolides, tetracyclines and fluoroquinolones (in that order, from high to low) are much rarer, and are identifiable only through large-scale studies or worldwide pharmacovigilance reporting. For antibiotics specifically used for tuberculosis, adverse effects range from asymptomatic increases in liver enzymes to acute hepatitis and fulminant hepatic failure. Yet, it is difficult to single out individual drugs, as treatment always entails associations. Patients at risk are mainly those with previous experience of hepatotoxic reaction to antibiotics, the aged or those with impaired hepatic function in the absence of close monitoring, making it important to carefully balance potential risks with expected benefits in primary care. Pharmacogenetic testing using the new genome-wide association studies approach holds promise for better understanding the mechanism(s) underlying hepatotoxicity

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
