Under-reporting of food intake is frequent among Brazilian free-living older persons: a doubly labelled water study

The assessment of food intake is essential for the development of dietetic interventions. Accuracy is low when intake is assessed by questionnaires, the under-reporting of food intake being frequent. Most such studies, however, were performed in developed countries and there is little data about the older population of developing nations. This study aimed to verify the total energy expenditure (TEE) of independent older Brazilians living in an urban area, through the doubly labelled water (DLW) method and to compare it with the reported energy intake obtained through the application of a food frequency questionnaire (FFQ). Initially, 100 volunteers aged from 60 to 75 years had their body composition determined by dual-energy X-ray absorptiometry (DEXA). Five volunteers of each quartile of body fat percentage had their energy expenditure determined by DLW. The mean age of the subjects included in this phase of the study was 66.4 +/- 3.5 years, and ten of the subjects were men. The mean TEE was 2565 +/- 614 and 2154 +/- 339 kcal.day(-1) for men and women, respectively. The Physical Activity Level (PAL) was 1.58 +/- 0.31 and 1.52 +/- 0.22, respectively. Under-reporting of food intake was highly prevalent, with a mean percentage of reported intake in relation to measured TEE of -17.7%. Thus, under-reporting of food intake is highly prevalent among Brazilian independent older persons. The DLW method is an important tool in nutritional studies and its use is to be recommended in developing countries. Copyright (C) 2010 John Wiley & Sons, Ltd.

Cervical range of motion discriminates between asymptomatic persons and those with whiplash

Study Design. A comparative study of cervical range of motion in asymptomatic persons and those with whiplash. Objectives. To compare the primary and conjunct ranges of motion of the cervical spine in asymptomatic persons and those with persistent whiplash-associated disorders, and to investigate the ability of these measures of range of motion to discriminate between the groups. Summary of Background. Evidence that range of motion is an effective indicator of physical impairment in the cervical spine is not conclusive. Few studies have evaluated the ability to discriminate between asymptomatic persons and those with whiplash on the basis of range of motion or compared three-dimensional in vivo measures of range of motion in asymptomatic persons and those with whiplash-associated disorders. Methods. The study participants were 89 asymptomatic volunteers (41 men, 48 women; mean age 39.2 years) and 114 patients with persistent whiplash-associated disorders (22 men, 93 women; mean age 37.2 years) referred to a whiplash research unit for assessment of their cervical region. Range of cervical motion was measured in three dimensions with a computerized, electromagnetic, motion-tracking device. The movements assessed were flexion, extension, left and right lateral flexion, and left and right rotation. Results. Range of motion was reduced in all primary movements in patients with persistent whiplash-associated disorder. Sagittal plane movements were proportionally the most affected. On the basis of primary and conjunct range of motion, age, and gender, 90.3% of study participants could be correctly categorized as asymptomatic or as having whiplash (sensitivity 86.2%, specificity 95.3%). Conclusions. Range of motion was capable of discriminating between asymptomatic persons and those with persistent whiplash-associated disorders.

Development of disabled, replication-defective gene transfer vectors from the Jembrana disease virus, a new infectious agent of cattle

Jembrana disease virus (JDV) is a newly isolated and characterised bovine lentivirus. It causes an acute disease in Ball cattle (Bos javanicus). which can be readily transmitted to susceptible cattle with 17% mortality. There is as yet no treatment or preventive vaccine. We have developed a gene transfer vector system based on JDV that has three components. The first of the components is a bicistronic transfer vector plasmid that was constructed to contain cis-sequences from the JDV genome, including 5 '- and 3 ' -long terminal repeats (LTRs), 0.4 kb of truncated gag and 1.1 kb of 3 ' -env, a multiple cloning site to accommodate the gene(s) of interest for transfer, and an internal ribosome entry site plus the neomycin phosphotransferase (Neo) gene cassette for antibiotic selection. The second element is a packaging plasmid that contains trans-sequences. including gag, pol. vif, tar and rev: but without the env and packaging signals. The third is a plasmid encoding the G glycoprotein of vesicular stomatitis virus (VSV-G) to supply the vector an envelope for pseudotyping. Cotransfection of 293T cells with these three plasmid components produced VSV-G pseudotyped. disabled, replication defective, bicistronic JDV vectors encoding the green fluorescent protein (EGFP) and the Neo resistance selection maker simultaneously with a titre range of (0.4-1.2) x 10(6) CFU/ml. Transduction of several replicating primary and transformed cells from cattle, primate and human sources and importantly growth-arrested cells with the JDV vectors showed high efficiency of EGFP gene transfer at 35-75%, which was stable and the expression of EGFP was long term. Furthermore, these JDV vectors were designed to suit the inclusion and expression of genes corresponding to JDV specific proteins, such as gag or env, for the development of vaccines for Jembrana disease. This strategy should also be applicable to other bovine diseases as wall. The design and construction of the JDV vector system should facilitate the study of the lentivirology and pathogenesis of the diseases associated with JDV or other bovine virus infections. To our knowledge, this is the first such vector system developed from a cattle virus. (C) 2001 Elsevier Science B.V. All rights reserved.

Nonverbal narratives: Listening to people with severe intellectual disability

This article describes an exploratory study that examined the perspectives of practitioners who spend much of their working day listening to and in some ways interpreting for people with severe intellectual disabilities. On the basis of focus group interviews with 23 professional disability-sector workers, including speech therapists, psychologists, and human service workers, the article reports on the importance of a practitioner's values and experience in successful interactions with individuals who rely on self-developed nonsymbolic communication repertoires. The article includes a discussion of the likelihood of including individuals with severe intellectual disabilities in narrative research.

Criminal Liability of Organizations, Corporations, Legal Persons, and Similar Entities on Law of Portuguese Cybercrime: A Brief Discussion on the Issue of Crimes of “False Information,” the “Damage on Other Programs or Computer Data,” the “Computer-Software Sabotage,” the “Illegitimate Access,” the “Unlawful Interception,” and “Illegitimate Reproduction of the Protected Program”

Abstract: in Portugal, and in much of the legal systems of Europe, «legal persons» are likely to be criminally responsibilities also for cybercrimes. Like for example the following crimes: «false information»; «damage on other programs or computer data»; «computer-software sabotage»; «illegitimate access»; «unlawful interception» and «illegitimate reproduction of protected program». However, in Portugal, have many exceptions. Exceptions to the «question of criminal liability» of «legal persons». Some «legal persons» can not be blamed for cybercrime. The legislature did not leave! These «legal persons» are v.g. the following («public entities»): legal persons under public law, which include the public business entities; entities utilities, regardless of ownership; or other legal persons exercising public powers. In other words, and again as an example, a Portuguese public university or a private concessionaire of a public service in Portugal, can not commit (in Portugal) any one of cybercrime pointed. Fair? Unfair. All laws should provide that all legal persons can commit cybercrimes. PS: resumo do artigo em inglês.

Service Provision for visually disabled adults by Social Service Departments in Portugal and England: a Comparative Perspective

Este artigo apresenta os principais resultados de um estudo de casos realizado sobre a prestação de serviços para adultos com deficiência visual pelos departamentos de acção social das autarquias em Portugal e Inglaterra. Emergiu da pesquisa que existem diferenças significativas nos serviços prestados aos adultos com deficiência visual tendo em conta que os departamentos de acção social daqueles dois países estão estruturados diferentemente e existem dentro de uma estrutura económica, social, cultural e política diferente. No entanto, podemos concluir que em Inglaterra a oferta de bens e serviços pelas instâncias municipais é mais abrangente, especializada e tem uma longa história de existência. Pelo contrário em Portugal o Estado-Providência tem uma história recente, e às autarquias é atribuído um papel suplementar no que diz respeito à prestação de serviços para pessoas com deficiência visual.

O aluno com deficiência motora e a acessibilidade arquitectónica no Ensino Básico : um estudo de caso : o concelho de Guimarães

RESUMO:Para que o sucesso educativo se verifique, a escola tem de ajustar a sua prática educativa a todos os alunos, incluindo os que apresentam necessidades educativas especiais (NEE). Portugal dispõe de legislação que assegura o direito à educação e à igualdade de oportunidades, consignados na Constituição da República Portuguesa (artigos 71º, 73º e 74º), em consonância com a Declaração Universal dos Direitos do Homem e na Lei de Bases do Sistema Educativo (artigos 2º, 7º, 17º e 18º). O nosso país subscreveu também a Declaração de Salamanca, a qual reuniu, em 1994, o consenso de noventa e dois governos e de vinte e cinco organizações internacionais, reafirmando o direito à educação para todos. A construção da escola inclusiva passa pela responsabilização da escola por todos os alunos, na perspectiva de educação para todos, exigindo a sua concretização novas estratégias e resposta a novos desafios. Há que alterar práticas para atender à diversidade. Assim, as escolas precisam de estar arquitectonicamente adaptadas às necessidades dos alunos que utilizam a cadeira de rodas como forma de mobilidade, respeitando o direito à diferença e possibilitando, em igualdade de oportunidades, o sucesso escolar e educativo. Levar à prática as medidas previstas na lei portuguesa e implementar, em cada escola, a inclusão do aluno com mobilidade condicionada, implica equipar as escolas com adaptações, meios e recursos educativos facilitadores do seu processo ensino/aprendizagem. A constatação do que efectivamente acontece no terreno educativo no que concerne aos alunos com deficiência motora que usam a cadeira de rodas para se movimentarem assume toda a centralidade da nossa investigação, que tem o cariz de um estudo de caso. Incide sobre a compreensão mais aprofundada de como se processa o acesso arquitectónico nas escolas do Ensino Básico da Zona Norte e mais concretamente do Concelho de Guimarães. Recolhemos dados através de questionários dirigidos aos professores de apoio educativo e coordenadores de escola; ouvimos os alunos com deficiência motora pronunciar-se sobre as dificuldades que sentiam; observámos o seu quotidiano escolar e, finalmente, escutámos as entidades locais, através de uma entrevista realizada à Vereadora da Cultura do Concelho de Guimarães. Os resultados obtidos serão, como foi acordado, divulgados aos intervenientes com responsabilidades directas no campo da educação que se prontificaram a partilhar connosco a sua informação e saber, no sentido de os sensibilizar para a necessidade de rever o aspecto das acessibilidades arquitectónicas nas instituições educativas que servem o seu concelho, pois, como verificámos, muito há ainda a fazer para que o Ensino Básico, universal e obrigatório, se traduza numa igualdade de oportunidades de acesso e sucesso educativo para os alunos que utilizam a cadeira de rodas para se movimentarem no espaço escolar. ABSTRACT: For the educational success of a school it has to adjust its educational practice so that it includes those with special needs. According to the Portuguese law, disabled people have the right to education and equal opportunities, well expressed in the Constitution of the Portuguese Republic (articles 71st, 73rd, and 74th), in consonance with the Universal Declaration of Human Rights, and in the main law the educational system (articles 2nd, 7th, 17th and 18th). Our country has also subscribed the Declaration of Salamanca, which was written in 1994 with the agreement of Representatives from ninety-two governments and twenty-five International Organizations, where was reaffirmed the right of education for all. It is necessary that school increases its responsibility in what concerns the education of all its students. Educating all and every student demands new strategies to face new challenges and so some practices have to be changed to respond to diversity. Schools must be architecturally adapted to give the disabled students, who use a wheel chair, equal opportunities to achieve educational success. Taking the measures foreseen in Portuguese law into practice, and implementing in each school the inclusion of students with conditioned mobility, involves equipping schools with adaptations, equipment and educational resources that facilitate the teaching / learning process. The observation of what actually happens on educative ground, regarding to pupils with motor disabilities who use a wheelchair to move, assumes the centrality of our research, which is a case study. It focuses on the deeper understanding of the way the architectonic access in primary schools of the North, and more specifically the Municipality of Guimarães, is processed. We collected data through questionnaires addressed to educational support teachers and school coordinators; heard students with motor disabilities to comment on the difficulties they felt; observed their daily school life, and finally heard the local authorities, through an interview the Councillor of Culture of the Municipality of Guimarães. As agreed, the results will be communicated to intervenients with direct responsibilities in the field of education who were willing to share with us their information and knowledge in order to raise awareness of the need of looking over the aspect of architectural accessibility in educational institutions that serve their county, because, as noted, much remains to be done so that the basic education, universal and compulsory, will result in equality of educational opportunities in access and success for students who use a wheelchair to move in school space.

Knee muscle strength, balance and functional independence in persons with stroke

Purpose: to investigate the relationship between knee muscle strength, balance and functional independence within the first month after stroke. Relevance: cerebral vascular disease is one of the main causes of morbidity, disability and mortality in developed countries. Problems with movement control are frequent after stroke. Lower limb weakness and impaired balance are common problems that are related with the risk of falls and are likely to interfere with the ability to perform daily life activities. Physiotherapy intervention usually starts early after stroke and addresses impairments related to movement and posture in order to improve motor recovery and restore function.

Effects of lower limb strengthening on balance and function in persons who suffered a stroke

Introduction - Cerebrovascular diseases, and among them, cerebral vascular accidents, are one of the main causes of morbidity and disability at European Union countries. Clinical framework resulting from these diseases include important limitations in functional ability of the these patients Postural control dysfunctions are one of the most common and devastating consequences of a stroke interfering with function and autonomy and affecting different aspects of people’s life and contributing to decrease quality of life. Neurological physiotherapy plays a central role in the recovery of movement and posture, however it is necessary to study the efficacy of techniques that physiotherapists use to treat these problems. Objectives - The aim of this study was to investigate the effects of a physiotherapy intervention program, based on oriented tasks and strengthening of the affected lower limb, on balance and functionality of individuals who have suffered a stroke. In addition our study aimed to investigate the effect of strength training of the affected lower limb on muscle tone.

The D1822V APC polymorphism interacts with fat, calcium, and fiber intakes in modulating the risk of colorectal cancer in Portuguese persons

Background - Both genetic and environmental factors affect the risk of colorectal cancer (CRC). Objective - We aimed to examine the interaction between the D1822V polymorphism of the APC gene and dietary intake in persons with CRC. Design - Persons with CRC (n = 196) and 200 healthy volunteers, matched for age and sex in a case-control study, were evaluated with respect to nutritional status and lifestyle factors and for the D1822V polymorphism. Results - No significant differences were observed in energy and macronutrient intakes. Cases had significantly (P < 0.05) lower intakes of carotenes, vitamins C and E, folate, and calcium than did controls. Fiber intake was significantly (P = 0.004) lower in cases than in controls, whereas alcohol consumption was associated with a 2-fold risk of CRC. In addition, cases were significantly (P = 0.001) more likely than were controls to be sedentary. The homozygous variant for the APC gene (VV) was found in 4.6% of cases and in 3.5% of controls. Examination of the potential interactions between diet and genotype found that a high cholesterol intake was associated with a greater risk of colorectal cancer only in noncarriers (DD) of the D1822V APC allele (odds ratio: 1.66; 95% CI: 1.00, 2.76). In contrast, high fiber and calcium intakes were more markedly associated with a lower risk of CRC in patients carrying the polymorphic allele (DV/VV) (odds ratio: 0.50; 95% CI: 0.27, 0.94 for fiber; odds ratio: 0.51; 95% CI: 0.28, 0.93 for calcium) than in those without that allele. Conclusion - These results suggest a significant interaction between the D1822V polymorphism and the dietary intakes of cholesterol, calcium, and fiber for CRC risk.

Serologic studies on the behaviour of influenza virus type A in persons of greater São Paulo during 1976, 1978 and 1979

Sera of persons of different age groups collected in 1976, 1978 and 1979 were tested for the presence of HI antibodies against various strains of the H3N2 and H1N1 subtypes of influenza virus. The occurrence of infection by H3N2 subtype was recorded during the 1976-1978 period but in 1979, circulation of this subtype of virus was limited. The prevalence of antibody against A/São Paulo/1/78 (H1N1) was significantly higher than that of antibody to A/USSB/90/77 (HIND in 1978. However in 1979 the predominant strain was A/USSR/90/77 (HIND. Persons under 20 years of age were the most affected by H1N1 subtype. Antibodies to H1N1 subtype were detected in sera of individuals older than 20 years in 1976, before the re-emergence of this strain. Serological results indicate that infections by H3N2 subtype in 1978 occurred in 65.4% of young children (0-4 year group). About 47.0% of children from the 0-4 year group had antibodies to H1N1 subtype in 1979. Antibodies to swine influenza virus were detected in 60% of 60+ year old people.

Postaerobic Exercise Blood Pressure Reduction in Very Old Persons With Hypertension.

BACKGROUND AND PURPOSE: A single bout of aerobic exercise acutely decreases blood pressure, even in older adults with hypertension. Nonetheless, blood pressure responses to aerobic exercise in very old adults with hypertension have not yet been documented. Therefore, this study aimed to assess the effect of a single session of aerobic exercise on postexercise blood pressure in very old adults with hypertension. METHODS: Eighteen older adults with essential hypertension were randomized into exercise (N = 9, age: 83.4 ± 3.2 years old) or control (N = 9, age: 82.7 ± 2.5 years old) groups. The exercise group performed a session of aerobic exercise constituting 2 periods of 10 minutes of walking at an intensity of 40% to 60% of the heart rate reserve. The control group rested for the same period of time. Anthropometric variables and medication status were evaluated at baseline. Heart rate and systolic and diastolic blood pressures were measured at baseline, after exercise, and at 20 and 40 minutes postexercise. RESULTS: Systolic blood pressure showed a significant interaction for group × time (F3,24 = 6.698; P = .002; ηp = 0.153). In the exercise group, the systolic blood pressure at 20 (127.3 ± 20.9 mm Hg) and 40 minutes (123.7 ± 21.0 mm Hg) postexercise was significantly lower in comparison with baseline (135.6 ± 20.6 mm Hg). Diastolic blood pressure did not change. Heart rate was significantly higher after the exercise session. In the control group, no significant differences were observed. CONCLUSIONS: A single session of aerobic exercise acutely reduces blood pressure in very old adults with hypertension and may be considered an important nonpharmacological strategy to control hypertension in this age group.
