Long-term effects of fenofibrate on lipoproteins and surrogate markers of macrovascular and microvascular disease in people with type 2 diabetes

Background and aims. Diabetic dyslipidemia is a highly atherogenic triad of increased triglycerides, decreased HDL cholesterol, and small dense LDL. Fibrates have a beneficial effect on diabetic dyslipidemia, and they have reduced cardiovascular events in randomized trials. Fenofibrate has reduced albuminuria and markers of low-grade inflammation and endothelial dysfunction. The present studies were undertaken to characterize the alterations of VLDL and LDL subclasses and to investigate the binding of LDL to arterial wall in type 2 diabetes. Further purpose was to elucidate the effects of fenofibrate on several lipoprotein subclasses, augmentation index (AIx), carotid intima-media thickness (IMT), and renal function. Subjects. 239 type 2 diabetic subjects were recruited among participants of the FIELD (Fenofibrate Intervention and Event Lowering in Diabetes) study at the Helsinki centre. The patients were randomized to fenofibrate (200mg/d) or placebo for 5 years. Additionally, a healthy control group (N = 93) was recruited. Results. VLDL1 triglycerides increased in similar proportion to total triglycerides in type 2 diabetic patients and control subjects. Despite the increase in total apoCIII levels, VLDL apoCIII was decreased in diabetic patients. Enrichment of LDL with apoCIII induced a small increase in binding of LDL to arterial wall proteoglycan. Intrinsic characteristics of diabetic LDL, rather than levels of apoCIII, were responsible for increased proteoglycan binding of diabetic LDL with high apoCIII. Fenofibrate reduced triglycerides, increased LDL size, and shifted HDL subclasses towards smaller particles with no change in levels of HDL cholesterol. High levels of homocysteine were associated with lower increase of HDL cholesterol and apoA-I during fenofibrate treatment. Long-term fenofibrate treatment did not improve IMT, AIx, inflammation, or endothelial function. Fenofibrate decreased creatinine clearance and estimated glomerular filtration rate. No effect on albuminuria was seen with fenofibrate. Instead, Cystatin C was increased during fenofibrate treatment. Conclusions. 1) Elevation of VLDL 1 triglycerides was the major determinant of plasma triglyceride concentration in control subjects and type 2 diabetic patients. 2) LDL with high apoCIII showed multiple atherogenic properties, that were only partially mediated by apoCIII per se in type 2 diabetes 3) Fenofibrate demonstrated no effect on surrogate markers of atherosclerosis. 4) Fenofibrate had no effect on albuminuria and the observed decrease in markers of renal function could complicate the clinical surveillance of the patients. 5) Fenofibrate can be used to treat severe hypertriglyceridemia or in combination therapy with statins, but not to increase HDL levels.

Investigation of a suicide ideation risk profile in people with co-occurring depression and substance use disorder

Disengagement from services is common before suicide, hence identifying factors at treatment presentation that predict future suicidality is important. This article explores risk profiles for suicidal ideation among treatment seekers with depression and substance misuse. Participants completed assessments at baseline and 6 months. Baseline demographics, psychiatric history, and current symptoms were entered into a decision tree to predict suicidal ideation at follow-up. Sixty-three percent of participants at baseline and 43.5% at follow-up reported suicidal ideation. Baseline ideation most salient when psychiatric illness began before adulthood, increasing the rate of follow-up ideation by 16%. Among those without baseline ideation, dysfunctional attitudes were the most important risk factor, increasing rates of suicidal ideation by 35%. These findings provide evidence of factors beyond initial diagnoses that increase the likelihood of suicidal ideation and are worthy of clinical attention. In particular, providing suicide prevention resources to those with high dysfunctional attitudes may be beneficial.

HealthMap: A cluster randomised trial of interactive health plans and self-management support to prevent coronary heart disease in people with HIV

Background The leading causes of morbidity and mortality for people in high-income countries living with HIV are now non-AIDS malignancies, cardiovascular disease and other non-communicable diseases associated with ageing. This protocol describes the trial of HealthMap, a model of care for people with HIV (PWHIV) that includes use of an interactive shared health record and self-management support. The aims of the HealthMap trial are to evaluate engagement of PWHIV and healthcare providers with the model, and its effectiveness for reducing coronary heart disease risk, enhancing self-management, and improving mental health and quality of life of PWHIV. Methods/Design The study is a two-arm cluster randomised trial involving HIV clinical sites in several states in Australia. Doctors will be randomised to the HealthMap model (immediate arm) or to proceed with usual care (deferred arm). People with HIV whose doctors are randomised to the immediate arm receive 1) new opportunities to discuss their health status and goals with their HIV doctor using a HealthMap shared health record; 2) access to their own health record from home; 3) access to health coaching delivered by telephone and online; and 4) access to a peer moderated online group chat programme. Data will be collected from participating PWHIV (n = 710) at baseline, 6 months, and 12 months and from participating doctors (n = 60) at baseline and 12 months. The control arm will be offered the HealthMap intervention at the end of the trial. The primary study outcomes, measured at 12 months, are 1) 10-year risk of non-fatal acute myocardial infarction or coronary heart disease death as estimated by a Framingham Heart Study risk equation; and 2) Positive and Active Engagement in Life Scale from the Health Education Impact Questionnaire (heiQ). Discussion The study will determine the viability and utility of a novel technology-supported model of care for maintaining the health and wellbeing of people with HIV. If shown to be effective, the HealthMap model may provide a generalisable, scalable and sustainable system for supporting the care needs of people with HIV, addressing issues of equity of access.

“Well this is it. Just get on with it”: Pain willingness and activity engagement in people with chronic pain

Pain is recognised as a problem of significant concern worldwide and in the latest Global Burden of Disease Study, low back pain was identified as the biggest contributor worldwide to Years Lived with Disability. There is evidence to suggest that people who accept their chronic pain have a higher quality of life, lower levels of disability and distress, and function better emotionally, socially and physically. Findings on the specific pathways linking pain acceptance to quality of life outcomes are less clear. the two widely accepted pain acceptance factors, pain willingness and activity engagement, have not been well explored in qualitative studies on acceptance of chronic pain. To address this deficit in the literature, the current study has two related aims: 1) to explore pain willingness and activity engagement in the lives of people with chronic pain, and ; 2) to find out what people believe helps them to successfully get on with life in spite of chronic pain.

Functional outcome and health-related quality of life after traumatic brain injury in the framework of the International Classification of Functioning, Disability and Health (ICF)

Traumatic brain injury (TBI) affects people of all ages and is a cause of long-term disability. In recent years, the epidemiological patterns of TBI have been changing. TBI is a heterogeneous disorder with different forms of presentation and highly individual outcome regarding functioning and health-related quality of life (HRQoL). The meaning of disability differs from person to person based on the individual s personality, value system, past experience, and the purpose he or she sees in life. Understanding of all these viewpoints is needed in comprehensive rehabilitation. This study examines the epidemiology of TBI in Finland as well as functioning and HRQoL after TBI, and compares the subjective and objective assessments of outcome. The frame of reference is the International Classification of Functioning, Disability and Health (ICF). The subjects of Study I represent the population of Finnish TBI patients who experienced their first TBI between 1991 and 2005. The 55 Finnish subjects of Studies II and IV participated in the first wave of the international Quality of life after brain injury (QOLIBRI) validation study. The 795 subjects from six language areas of Study III formed the second wave of the QOLIBRI validation study. The average annual incidence of Finnish hospitalised TBI patients during the years 1991-2005 was 101:100 000 in patients who had TBI as the primary diagnosis and did not have a previous TBI in their medical history. Males (59.2%) were at considerably higher risk of getting a TBI than females. The most common external cause of the injury was falls in all age groups. The number of TBI patients ≥ 70 years of age increased by 59.4% while the number of inhabitants older than 70 years increased by 30.3% in the population of Finland during the same time period. The functioning of a sample of 55 persons with TBI was assessed by extracting information from the patients medical documents using the ICF checklist. The most common problems were found in the ICF components of Body Functions (b) and Activities and Participation (d). HRQoL was assessed with the QOLIBRI which showed the highest level of satisfaction on the Emotions, Physical Problems and Daily Life and Autonomy scales. The highest scores were obtained by the youngest participants and participants living independently without the help of other people, and by people who were working. The relationship between the functional outcome and HRQoL was not straightforward. The procedure of linking the QOLIBRI and the GOSE to the ICF showed that these two outcome measures cover the relevant domains of TBI patients functioning. The QOLIBRI provides the patients subjective view, while the GOSE summarises the objective elements of functioning. Our study indicates that there are certain domains of functioning that are not traditionally sufficiently documented but are important for the HRQoL of persons with TBI. This was the finding especially in the domains of interpersonal relationships, social and leisure activities, self, and the environment. Rehabilitation aims to optimize functioning and to minimize the experience of disability among people with health conditions, and it needs to be based on a comprehensive understanding of human functioning. As an integrative model, the ICF may serve as a frame of reference in achieving such an understanding.

A comparative phase 1 clinical trial to identify anti-infective mechanisms of vitamin D in people with HIV infection

Objectives:To determine if there is a biological mechanism that explains the association between HIV disease progression and increased mortality with low circulating vitamin D levels; specifically, to determine if restoring vitamin D levels induced T-cell functional changes important for antiviral immunity.Design:This was a pilot, open-label, three-arm prospective phase 1 study.Methods:We recruited 28 patients with low plasma vitamin D (<50nmol/l 25-hydroxyvitamin D3), comprising 17 HIV+ patients (11 on HAART, six treatment-naive) and 11 healthy controls, who received a single dose of 200000IU oral cholecalciferol. Advanced T-cell flow cytometry methods measured CD4(+) T-cell function associated with viral control in blood samples at baseline and 1-month after vitamin D supplementation.Results:One month of vitamin D supplementation restored plasma levels to sufficiency (>75nmol/l) in 27 of 28 patients, with no safety issues. The most striking change was in HIV+ HAART+ patients, where increased frequencies of antigen-specific T cells expressing macrophage inflammatory protein (MIP)-1 - an important anti-HIV blocking chemokine - were observed, with a concomitant increase in plasma MIP-1, both of which correlated significantly with vitamin D levels. In addition, plasma cathelicidin - a vitamin D response gene with broad antimicrobial activity - was enhanced.Conclusion:Vitamin D supplementation modulates disease-relevant T-cell functions in HIV-infected patients, and may represent a useful adjunct to HAART therapy.

História de Vida de alunos com deficiência intelectual: percurso escolar e a constituição do sujeito

Esta tese procura compreender o processo de inclusão escolar dos alunos com deficiência intelectual a partir das suas histórias de vida e da percepção que eles têm da escola, considerando a relação entre deficiência, escola e construção do conhecimento. A pesquisa foi realizada em uma escola do campo, pertencente à rede pública estadual do município de Teresópolis no Rio de Janeiro. Objetivo principal foi compreender o processo de inclusão das pessoas com deficiência intelectual na escola regular a partir das histórias de cinco jovens inseridos na rede regular de ensino. Tratou-se de uma pesquisa qualitativa norteada pelo método da história de vida, segundo os pressupostos de Glat (2009), Augras (2009), Ferrarotti (1993) e outros. O referencial teórico adotado no estudo pautou-se na abordagem psicossocial da deficiência, ressaltando a relação que a pessoa com deficiência estabelece com o meio social e cultural do qual faz parte. A partir das histórias de vida dos sujeitos foi possível compreender como os jovens narram sua trajetória escolar, com destaque para as seguintes categorias: 1) trajetória escolar, 2) o papel da escola; 3) relação com os professores e as disciplinas; 4) relação com os colegas dentro e fora da escola; 5) perspectivas de futuro e transição para a vida adulta. O estudo revelou as contradições e a complexidade do processo de inclusão de alunos com deficiência intelectual em escolas comuns, particularmente quando se trata da inserção de jovens no segundo segmento do Ensino Fundamental e no Ensino Médio. Percebemos que mesmo após anos de discussões e pesquisas sobre a inclusão escolar de alunos com deficiência intelectual suas trajetórias ainda são marcadas pela cultura da incapacidade e do descrédito em relação ao que esses alunos podem fazer. As políticas de inclusão, embora bastante avançadas do ponto de vista de suas concepções teóricas, na prática não se traduzem na superação de práticas homogeneizadoras de ensino e organização do espaço escolar. Esperamos que esta pesquisa contribua significativamente para o contexto da educação brasileira, seja no âmbito da escola comum ou da Educação Especial, de maneira que as falas que aqui foram apresentadas ecoem e signifiquem um ponto de reflexão sobre como os sistemas educacionais e nós mesmos estamos compreendendo o processo de inclusão de alunos com deficiência e outras necessidades especiais na escola e na sociedade.

Capacitação de pessoas com deficiência intelectual para o trabalho: estudo de caso de um curso de capacitação profissional

Este estudo teve como objetivo a análise de um curso de capacitação profissional para alunos com deficiência intelectual numa escola especial. Os objetivos específicos foram: a) analisar o desenvolvimento social e o desempenho dos alunos nas atividades do curso; b) investigar as expectativas dos alunos e seus familiares em relação ao papel da escola especial no contexto da capacitação profissional; c) compartilhar o conhecimento produzido na escola especial e na universidade sobre alternativas pedagógicas para o ensino de alunos com deficiência intelectual. Para atender aos objetivos foi realizado um estudo de caso por meio da metodologia da pesquisa-ação, a qual consistiu de um trabalho colaborativo entre a pesquisadora e a professora da turma. Entre os procedimentos incluem-se observações das atividades do curso; entrevistas com a professora, funcionário da escola, alunos do curso e seus familiares. A análise dos dados destacou como aspectos relevantes: o desenvolvimento de uma proposta diferenciada de formação profissional para este alunado, a investimento pessoal da professora em uma capacitação para aprender a ensinar em um novo contexto, e a inciativa da escola de buscar parcerias para implementação de mudanças no seu escopo de atuação enquanto instituição especializada. A escuta dos alunos, seus familiares e uma profissional da escola colaborou para a proposição de novas ações dentro do contexto investigado. Nos dados obtidos também se evidenciou que as atividades de aula planejadas pela professora do curso foram determinantes para o bom desempenho dos alunos, sobretudo por serem realizadas no contexto real onde tais ações se executam. O trabalho colaborativo da pesquisadora e da professora viabilizando a elaboração de um plano individual de acompanhamento para os alunos no treinamento pode ser apontado como uma alternativa para o planejamento do processo de transição para a vida pós-escola. Entre outros aspectos, as entrevistas com os responsáveis indicaram a necessidade de um trabalho mais pontual da equipe da escola com as famílias sobre a perspectiva de vida pós-escolar dos alunos. De forma mais geral, o estudo de caso demonstrou que a escola especial, tem procurado encontrar caminhos para sua ressignificação por meio da aproximação e parceria com a universidade. Os dados obtidos permitem concluir que a formação continuada dos professores para atuar na capacitação profissional de alunos com deficiência intelectual é um processo que necessita do trabalho colaborativo de diferentes atores, conforme apontado pela própria professora do curso analisado.

Aplicação e análise de um programa customizado para a inclusão de jovens com deficiência intelectual em atividades laborais.

A presente pesquisa tem por objetivo implementar e avaliar um programa de inserção de jovens com deficiência intelectual em atividades laborais na Faculdade de Educação da Universidade do Estado do Rio de Janeiro.Para tal, foi utilizado o conceito de emprego customizado, que baseia-se na criação e/ou adaptação de postos de trabalho em empresas e outras instituições, se adequando a demanda do empregadorcom as habilidades do sujeito com deficiência, de forma a criar uma função que atenda às necessidades de ambas as partes. Um dos procedimentos da customização do trabalho é o Perfil Pessoal Positivo PPP, uma estratégia para traçar as habilidades e dificuldades dos jovens e adultos com deficiência, de forma a facilitar sua inserção no mercado de trabalho e outros espaços sociais. Participaram da pesquisa quatro jovens com deficiência intelectual, denominados treinandos indicados pelos professores de uma escola especial da rede pública do Estado do Rio de Janeiro, oriundos decursos de formação inicial e continuada em auxiliar de serviços gerais e auxiliar de contínuo-reprografia. Utilizou-se a metodologia de pesquisa-ação, com dados colhidos através de entrevistas semiestruturadas com os sujeitos com deficiência intelectual e os funcionários da Faculdade de Educação, assim como observação de seu desempenho. Como dados complementares, também foram realizadas entrevistas semiestruturadas com as mães dos jovens e os funcionários da Faculdade de Educação que aturaram diretamente com os treinandos. As entrevistas iniciais com os treinandos serviram como base para traçar seu o PPP, e determinar que atividades seriam mais adequadas para eles. Já as realizadas com os gestores da Faculdade, visaram compreender a dinâmica de funcionamento e as necessidades de trabalho da instituição.A elaboração do PPPpermitiu romperas barreiras impostas pelas exigências do mercado de trabalho, como escolarização mínima, capacitação, entre outras, pois, compreendendo as características do sujeito, é possível encontrar funções laborais que se adequem às suas singularidades e, ao mesmo tempo, atendam às necessidades do empregador. Concluímos, com base nos dados colhidos, que analisar o ambiente de trabalho com o objetivo de oferecer mão deobra adequada para a demanda é pré-requisito para a contratação e inclusão laboral de pessoas com deficiência. A customização do emprego contribui para a eliminação das barreiras atitudinais e preconceitos, aumentando as probabilidades de um desempenho e produção laboral satisfatória, beneficiando, tanto a instituição quanto o funcionário.

Influence of depression in a sample of people with hallux valgus

Hallux valgus (HV) is a highly-prevalent forefoot deformity associated with progressive subluxation and osteoarthritis of the first metatarsophalangeal joint; it is believed to be associated with depression. The aim of the present study was to determine the association of patients with varying degrees of HV involvement to depression using the Beck Depression Inventory (BDI). The sample consisted of 102 participants (mean age: 45.1±1.6), who attended an outpatient centre where self-report data were recorded. The degree of HV deformity was determined in both feet, and the scores on the BDI were compared. A total of 38.24% of the sample had depression, with an average BDI score of 10.55±12.36 points. There was a statistically-significant association between the degree and presence of HV in both feet (P=0.0001). People with a greater degree of HV deformity in any foot also have a significant increase in depression based on BDI scores, regardless of sex.

Camera-Based Interfaces and Assistive Software for People with Sever Motion Impairments

Intelligent assistive technology can greatly improve the daily lives of people with severe paralysis, who have limited communication abilities. People with motion impairments often prefer camera-based communication interfaces, because these are customizable, comfortable, and do not require user-borne accessories that could draw attention to their disability. We present an overview of assistive software that we specifically designed for camera-based interfaces such as the Camera Mouse, which serves as a mouse-replacement input system. The applications include software for text-entry, web browsing, image editing, animation, and music therapy. Using this software, people with severe motion impairments can communicate with friends and family and have a medium to explore their creativity.
