Favorable effect on acute and chronic graft-versus-host disease with cyclophosphamide and in vivo anti-CD52 monoclonal antibodies for marrow transplantation from HLA-identical sibling donors for acquired aplastic anemia

Between August 1989 and November 2003, 33 patients at our center with acquired aplastic anemia underwent bone marrow transplantation (BMT) from HLA-identical sibling donors with cyclophosphamide and in vivo anti-CD52 monoclonal antibodies (MoAb) for conditioning. The median age at BMT was 17 years (range, 4-46 years). Before BMT, 58% were heavily transfused (>50 transfusions), and 42% had previously experienced treatment failure with antithymocyte globulin-based immunosuppressive therapy. Unmanipulated bone marrow was used as the source of stem cells in all patients except 1. Graft-versus-host disease (GVHD) prophylaxis was with cyclosporine alone in 19 (58%) patients; 14 received anti-CD52 MoAb in addition to cyclosporine. The conditioning regimen was well tolerated without significant acute toxicity. Graft failure was seen in 8 patients (primary, n = 4; secondary, n = 4). Of those whose grafts failed, 4 survived long-term (complete autologous recovery, n = 2; rescue with previously stored marrow, n = 1; second allograft, n = 1). The cumulative incidence of graft failure and grade II to IV acute and chronic GVHD was 24%, 14%, and 4%, respectively. None developed extensive chronic GVHD. With a median follow-up of 59 months, the 5-year survival was 81% (95% confidence interval, 68%-96%). No unexpected early or late infectious or noninfectious complications were observed. We conclude that the conditioning regimen containing cyclophosphamide and anti-CD52 MoAb is well tolerated and effective for acquired aplastic anemia with HLA-matched sibling donors. The favorable effect on the incidence and severity of GVHD is noteworthy in this study and warrants further investigation.

The prognostic significance of protein tyrosine phosphatase 4A2 in breast cancer

Although PTP4A3 has been shown to be a very important factor in promoting cancer progression, the role of its close family member PTP4A2 is still largely unknown. Recent reports have shown contradicting results on the role of PTP4A2 in breast cancer progression. Considering this, we aimed to investigate the prognostic value of PTP4A2 in five independent breast cancer data sets (minimum 198 patients per cohort, totaling 1,124 patients) in the Gene Expression Omnibus Database. We found that high expression of PTP4A2 was a favorable prognostic marker in all five independent breast cancer data sets, as well as in the combined cohort, with a hazard ratio of 0.68 (95% confidence interval =0.56-0.83; P<0.001). Low PTP4A2 expression was associated with estrogen receptor-negative tumors and tumors with higher histological grading; furthermore, low expression was inversely correlated with the expression of genes involved in proliferation, including MKI67 and the MCM gene family encoding the minichromosome maintenance proteins. These findings suggest that PTP4A2 may play a role in breast cancer progression by dysregulating cell proliferation. PTP4A2 expression was positively correlated with ESR1, the gene encoding estrogen receptor-alpha, and inversely correlated with EGFR expression, suggesting that PTP4A2 may be involved in these two important oncogenic pathways. Together, our results suggest that expression of PTP4A2 is a favorable prognostic marker in breast cancer.

Evaluation of the ionic liquids 1-alkyl-3-methylimidazolium hexafluorophosphate as a solvent for the extraction of benzene from cyclohexane : ( Liquid + liquid ) equilibria

In the catalytic hydrogenation of benzene to cyclohexane, the separation of unreacted benzene from the product stream is inevitable and essential for an economically viable process. In order to evaluate the separation efficiency of ionic liquids (ILs) as a solvent in this extraction processes, the ternary (liquid + liquid) equilibrium of 1-alkyl-3-methylimidazolium hexafluorophosphate, [Cnmim][PF6] (n = 4, 5, 6), with benzene and cyclohexane was studied at T = 298.15 K and atmospheric pressure. The reliability of the experimentally determined tie-line data was confirmed by applying the Othmer–Tobias equation. The solute distribution coefficient and solvent selectivity for the systems studied were calculated and compared with literature data for other ILs and sulfolane. It turns out that the benzene distribution coefficient increases and solvent selectivity decreases as the length of the cation alkyl chain grows, and the ionic liquids [Cnmim][PF6] proved to be promising solvents for benzene–cyclohexane extractive separation. Finally, an NRTL model was applied to correlate and fit the experimental LLE data for the ternary systems studied.

Deep separation of benzene from cyclohexane by liquid extraction using ionic liquids as the solvent

Separation of benzene and cyclohexane is one of the most important and difficult processes in the petrochemical industry, especially for low benzene concentration. In this work, three ionic liquids (ILs), [Bmim][BF ₄], [Bpy][BF ₄], and [Bmim][SCN], were investigated as the solvent in the extraction of benzene from cyclohexane. The corresponding ternary liquid-liquid equilibria (LLE) were experimentally determined at T = 298.15 K and atmospheric pressure. The LLE data were correlated with the nonrandom two-liquid model, and the parameters were fitted. The separation capabilities of the ILs were evaluated in terms of the benzene distribution coefficient and solvent selectivity. The effect of the IL structure on the separation was explained based on a well-founded physical model, COSMO-RS. Finally, the extraction processes were defined, and the operation parameters were analyzed. It shows that the ILs studied are suitable solvents for the extractive separation of benzene and cyclohexane, and their separation efficiency can be generally ranked as [Bmim][BF ₄] > [Bpy][BF ₄] > [Bmim][SCN]. The extraction process for a feed with 15 mol % benzene was optimized. High product purity (cyclohexane 0.997) and high recovery efficiency (cyclohexane 96.9% and benzene 98.1%) can be reached. © 2012 American Chemical Society.

PRL-3 activates mTORC1 in Cancer Progression

PRL-3, a metastasis-associated phosphatase, is known to exert its oncogenic functions through activation of PI3K/Akt, which is a key regulator of the rapamycin-sensitive mTOR complex 1 (mTORC1), but a coherent link between PRL-3 and activation of mTOR has not yet been formally demonstrated. We report a positive correlation between PRL-3 expression and mTOR phospho-activation in clinical tumour samples and mouse models of cancer and demonstrate that PRL-3 increased downstream signalling to the mTOR substrates, p70S6K and 4E-BP1, by increasing PI3K/Akt-mediated activation of Rheb-GTP via TSC2 suppression. We also show that PRL-3 increases mTOR translocation to lysosomes via increased mTOR binding affinity to Rag GTPases in an Akt-independent manner, demonstrating a previously undescribed mechanism of action for PRL-3. PRL-3 also enhanced matrix metalloproteinase-2 secretion and cellular invasiveness via activation of mTOR, attributes which were sensitive to rapamycin treatment. The downstream effects of PRL-3 were maintained even under conditions of environmental stress, suggesting that PRL-3 provides a strategic survival advantage to tumour cells via its effects on mTOR.

Interactions between pyrazole derived enantiomers and Chiralcel OJ: Prediction of enantiomer absolute configurations and elution order by molecular dynamics simulations

The separation of enantiomers and confirmation of their absolute configurations is significant in the development of chiral drugs. The interactions between the enantiomers of chiral pyrazole derivative and polysaccharide-based chiral stationary phase cellulose tris(4-methylbenzoate) (Chiralcel OJ) in seven solvents and under different temperature were studied using molecular dynamics simulations. The results show that solvent effect has remarkable influence on the interactions. Structure analysis discloses that the different interactions between two isomers and chiral stationary phase are dependent on the nature of solvents, which may invert the elution order. The computational method in the present study can be used to predict the elution order and the absolute configurations of enantiomers in HPLC separations and therefore would be valuable in development of chiral drugs.

O quadro interativo na aula de inglês : desenvolvimento de práticas comunicativas

Na sociedade da informação, o papel da escola como centro transmissor de conhecimentos está a perder relevância face ao crescente número de fontes de informação alternativas, ricas em conteúdos e de fácil acesso. A alteração de paradigmas cria a necessidade de se introduzirem nos contextos educacionais novas ferramentas e que se adequem estratégias que permitam motivar e ensinar os aprendentes a procurarem e a selecionarem essa informação, participando, desta forma, ativamente na construção do conhecimento. Neste contexto, consideramos que o quadro interativo, pela sua capacidade de funcionar como hub digital, permite integrar recursos dinâmicos e interativos facilitadores do acesso ao conhecimento e à informação. A dissertação que apresentamos, “O Quadro Interativo na aula de inglês: desenvolvimento de práticas comunicativas”, situa-se na área do Multimédia em Educação e, mais especificamente, no domínio da tecnologia e pedagogia em sala de aula. A investigação foi desenhada em torno de um projeto de implementação de quadros interativos (Inov@r com QI) em agrupamentos/escolas do interior do país, associado a um Centro de Formação. A partir de uma investigação qualitativa mista, baseada no tracer study (análise documental, entrevistas e questionários) e no estudo etnográfico (aulas observadas, entrevistas e questionários), procurámos evidenciar a forma como essa tecnologia levou à integração de recursos e à adoção de estratégias promotoras de um ensino e aprendizagem ativo, centrado no aprendente e criando dinâmicas de interação e comunicação facilitadoras do desenvolvimento da competência comunicativa. Os resultados obtidos revelam que a introdução do quadro interativo produz efeitos positivos no ensino e aprendizagem do inglês. A sua integração em contexto de sala de aula abre espaço a um conjunto de potencialidades pedagógicas, promove o uso de recursos digitais variados; leva a uma diversificação de abordagens metodológicas que promovem a interação, criando espaços que levam ao desenvolvimento da competência comunicativa. No entanto, para tornar a introdução do quadro interativo mais eficaz, como ferramenta educativa no processo de ensino e aprendizagem, devemos ter em conta que esse processo de introdução do quadro deve ser planeada e refletida, devendo ter em conta uma nova realidade de conceitos, a tecnologia e as literacias necessárias para uma implementação eficaz. Os docentes devem ser acompanhados, ter acesso a formação técnica e pedagógica; e a possibilidade de integrarem um espaço de colaboração e partilha, como forma mais eficaz de se libertarem de práticas centradas no docente e orientadas apenas para a aquisição de conteúdos. Assim será possível dar lugar a um discurso pedagógico que inclua os vários intervenientes no processo de aprendizagem e a construção de conhecimento, num espaço de interação suportado pela tecnologia

Structure-inhibition relationship of phenylethanoid glycosides on angiotensin-converting enzyme using ultra-performance liquid chromatography-tandem quadrupole mass spectrometry

Angiotensin-converting enzyme (ACE) plays a critical role in rennin-angiotensin system. Recently, natural products isolated from herbal medicines revealed inhibitory effects against ACE which suggested their potential activities in regulating blood pressure. In this study, ACE inhibition (ACEI) of 21 phenylethanoid glycosides and related phenolic compounds were investigated by measuring the production of HA a rapid, sensitive, accurate and specific ultra-performance liquid chromatography-tandem quadrupole mass spectrometry (UPLC-MS/MS) method. The test compounds showed different inhibitory potencies on ACE ranging from 5.29 to 95.01% at 50 mM, and the compounds with ACEI higher than 50% were selected for further IC50 determination. The IC50 values were from 0.53 ± 0.04 to 15.035 ± 0.036 mM. The structure-inhibition relationship were then explored and the result showed that cinnamoyl groups played an essential role in ACEI of phenylethanoid glycosides. Furthermore, the sub-structures of increasing ACEI for phenylethanoid glycosides is more hydroxyls and less steric hindrance to chelate the active site Zn2+ of ACE. In summary, our results suggested that phenylethanoid glycosides are a widely available source of anti-hypertensive natural products and the information provided from structure-inhibition relationship study could aid the design of structurally modified phenylethanoid glycosides as anti-hypertensive drugs.

Estigma e percepções dos médicos de Clínica Geral sobre a doença mental e o suicídio

RESUMO: INTRODUÇÃO: A OMS (2001) revela que cerca de 450 milhões de pessoas sofrem de perturbações mentais ou comportamentais em todo o mundo, mas apenas uma pequena minoria tem tratamento, ainda que elementar. Transformam-se em vítimas por causa da sua doença e convertem-se em alvos de estigma e discriminação. O suicídio é considerado como um grande problema de saúde pública em todo o mundo, é uma das principais causas de morte de jovens adultos e situa-se entre as três maiores causas de morte na população entre 15-34 anos (OMS, 2001). As perturbações mentais aumentam o risco de suicídio. A depressão, esquizofrenia, e a utilização de substâncias incrementam o risco de suicídio. Estudos (Sartorius, 2002; Magliano et al., 2012) mostram que os profissionais de saúde, tal como o público em geral, podem ter atitudes negativas e estigma em relação às pessoas com perturbações mentais, podendo agir em conformidade, uma vez feito e conhecido o diagnóstico psiquiátrico. Os clínicos gerais são os receptores das perturbações mentais e tentativas de suicídio nas principais portas de entrada no acesso a cuidados de saúde. As crenças, conhecimentos e contacto com a doença mental e o suicídio, podem influenciar a atenção clínica. OBJECTIVOS: Avaliar o estigma e as percepções dos médicos de clínica geral em relação às tentativas de suicídio, o suicídio e perturbações mentais bem como os possíveis factores associados a estes fenómenos. MATERIAIS E MÉTODOS: Estudo do tipo transversal, combinando métodos quantitativos e qualitativos. A amostra é constituída por 125 sujeitos, médicos de clínica geral. Utilizaram-se as versões adaptadas dos seguintes instrumentos: Questionário sobre Percepções e Estigma em Relação à Saúde Mental e ao Suicídio (Liz Macmin e SOQ, Domino, 2005) e a Escala de Atitudes sobre a Doença Mental (Amanha Hahn, 2002). Para o tratamento estatístico dos dados usou-se a estatística 1) descritiva e 2) Análise estatística das hipóteses formuladas (Qui Quadrado - 2) a correlação entre variáveis (Spearman: ρ, rho). Os dados conectados foram limpos de inconsistências com base no pacote informático e estatístico SPSS versão 20. Para a aferição da consistência interna foi usado o teste de Alfa de Cronbach. RESULTADOS: Uma boa parte da amostra (46.4%) refere que não teve formação formal ou informal em saúde mental e (69.35%) rejeitam a ideia de que “grupos profissionais como médicos, dentistas e psicólogos são mais susceptíveis a cometer o suicídio”. Já (28.0%) têm uma perspectiva pessimista quanto a possibilidade de recuperação total dos sujeitos com perturbação mental. Sessenta e oito(54.4%) associa sujeitos com perturbação mental, a comportamentos estranhos e imprevisíveis, 115 (92.0%) a um baixo QI e 35 (26.7%) a poderem ser violentas e e perigosas. Os dados mostram uma associação estatisticamente significativa (p0.001) entre as variáveis: tempo de serviço no SNS, recear estar perto de sujeitos com doença mental e achar que os sujeitos com doença mental são mais perigosos que outros. Em termos estatísticos, existe uma associação estatitisticamente significativa entre as duas variáveis(X2=9,522; p0.05): percepção de que “é vergonhoso ter uma doença mental” e os conhecimentos em relação à doença mental. Existe uma correlação positiva, fraca e estatisticamente significativa entre os conhecimentos dos clínicos gerais(beneficiar-se de formação em saúde mental) e a percepção sobre os factores de risco (0,187; P0,039). DISCUSSÃO E CONCLUSÕES: A falta de conhecimento sobre as causas e factores de risco para os comportamentos suicidários, opções de intervenção e tratamento, particularmente no âmbito da doença mental, podem limitar a procura de ajuda individual ou dos próximos. Percepções negativas como o facto de não merecerem prioridade nos serviços, mitos (frágeis e cobarde, sempre impulsivo, chamadas de atenção, problemas espirituais) podem constituir-se como um indicador de que os clínicos gerais podem sofrer do mesmo sistema de estigma e crenças, de que sofre o público em geral, podendo agir em conformidade (atitudes de afastamento ereceio). As atitudes são influenciadas por factores como a formação, cultura e sistema de crenças. Sujeitos com boa formação na área da saúde mental têm uma percepção positiva e optimista sobre os factores de risco e uma atitude positiva em relação aos sujeitos com doença mental e comportamentos suicidários.-------------ABSTRACT: INTRODUCTION: The WHO (2001) reveals that about 450 million people suffer from mental or behavioral disorders worldwide, but only a small minority have access to treatment, though elementary. They become victims because of their disease and they become the targets of stigma and discrimination. Suicide is seen as a major public health problem worldwide, is a leading cause of death for young adults and is included among the three major causes of death in the population aged 15-34 years (WHO, 2001). Mental disorders increase the risk of suicide. Depression, schizophrenia, and the substances misuse increase the risk of suicide. Studies (Sartorius, 2002; Magliano et al, 2012) show that health professionals, such as the general public, may have negative attitudes and stigma towards people with mental disorders, and can act accordingly after psychiatric diagnosis is known. General practitioners are the main entry points of mental disorders and suicide attempts in the health sistem. Beliefs, knowledge and contact with mental illness and suicide, may influence clinical care. OBJECTIVES: To assess stigma and perceptions of general practitioners in relation to suicide attempts, suicide and mental disorders as well as possible factors associated with these phenomena. MATERIAL AND METHODS: This was a descriptive cross-sectional study, combining quantitative and qualitative methods. The sample consisted of 125 subjects, general practitioners. We used adapted versions of the following instruments: Questionnaire of Perceptions and Stigma in Relation to Mental Health and Suicide (Liz Macmin and SOQ, Domino, 2005) and the Scale of Attitudes on Mental Illness (Tomorrow Hahn, 2002). For the statistical treatment of the data we used: 1) descriptive (Data distribution by absolute and relative frequencies for each of the variables under study (including mean and standard deviation measures of central tendency and deviation), 2) statistical analysis of hypotheses using (Chi Square - 2, a hypothesis test that is intended to find a value of dispersion for two nominal variables, evaluating the association between qualitative variables) and the correlation between variables (Spearman ρ, rho), a measure of non-parametric correlation, which evaluates an arbitrary monotonic function can be the description of the relationship between two variables, without making any assumptions about the frequency distribution of the variables). For statistical analysis of the correlations were eliminated subjects who did not respond to questions. The collected data were cleaned for inconsistencies based on computer and statistical package SPSS version 20. To measure the internal consistency was used the Cronbach's alpha test. RESULTS: A significant part of the sample 64 (46.4%) reported no formal or informal training in mental health and 86 (69.35%) reject the idea that "professional groups such as doctors, dentists and psychologists are more likely to commit suicide." On the other hand, 42 (28.0%) have a pessimistic view of the possibility of full recovery of individuals with mental disorder. Sixty-eight ( 54.4 % ) of them associates subjects with mental disorder to strange and unpredictable behavior, 115 ( 92.0 % ), to low IQ, 35 ( 26.7 % ) and even to violent and dangerous behavior, 78 ( 62.4 % ) The data show a statistically significant (p = 0.001) relationship between the following variables: length of service in the NHS, fear of being close to individuals with mental illness and considering individuals with mental illness more dangerous than others. In statistical terms, there is a dependency between the two variables (X2 = 9.522, p> 0.05): the perception that "it is shameful to have a mental illness" and knowledge regarding mental illness. There is a positive and statistically significant weak correlation between knowledge of general practitioners (benefit from mental health training) and the perception of the risk factors (0,187; P0,039). DISCUSSION AND CONCLUSIONS: The lack of knowledge about the causes and risk factors for suicidal behavior, intervention and treatment, particularly in the context of mental illness options, may decreaseseeking for help by individual and their relatives. Negative perceptions such as considering that they dont deserve priority in services, myths (weak and cowards, always impulsive, seeking for attentions, spirituals problems) may indicate that general practitioners, may suffer the same stigma and beliefs systems as the general public, and can act accordingly (withdrawal and fear attitudes). Attitudes are influenced by factors such as education, culture and belief system. Subjects with good training in mental health have a positive and optimistic perception of the risk factors and a positiveattitude towards individuals with mental illness and suicidal behaviour.

Classificação Internacional de Funcionalidade, Incapacidade e Saúde : uma dimensão do neurodesenvolvimento

RESUMO: Objetivo Principal • Determinar a consistência da utilização dos instrumentos de avaliação da capacidade intelectual – escalas de Griffiths e WISC III – no enquadramento dos domínios e dos qualificadores da CIF-CJ, restrita às funções mentais do corpo. Objetivo secundário: • Estudar a efetividade e concordância inter-observador da aplicação da CIF, com base na leitura dos dados obtidos em avaliação efetuada com os instrumentos referidos, por duas observadoras independentes, em contexto de articulação saúde, respetivamente educação e segurança social Métodos • Estudo observacional, descritivo, transversal e prospetivo. • Foi estudada uma amostra de conveniência 355 crianças, num período de três anos (Maio de 2010 a 30 de Abril de 2013), com patologia da área da pediatria do neurodesenvolvimento (total de 4000 consultas) no Centro de Desenvolvimento (CD) do Hospital de Dona Estefânia (HDE), Centro Hospitalar de Lisboa Central, EPE (CHLC, EPE). • Critérios de inclusão: crianças de ambos os sexos, observadas no CD do HDE, CHLC (primeiras consultas e consultas de reavaliação) com idade ≥12 meses e ≤17 anos e incapacidade intelectual definida de acordo com os critérios da DSM-IV-TR, DSM 5 e CID-10. • Critérios de exclusão: crianças com autismo, perturbações específicas da linguagem, hiperatividade, défice de atenção e concentração, défices sensoriais congénitos (baixa visão e ou audição), ou com outros diagnósticos de perturbações de neurodesenvolvimento. • O estudo teve duas fases: na primeira, a investigadora principal colheu ou atualizou a história clínica, observou clinicamente as crianças solicitando os exames complementares considerados necessários e foi efetuada avaliação psicológica com os instrumentos adiante descritos, pela mesma psicóloga clínica, devidamente credenciada, e com larga experiência nas escalas referidas. Com base nos dados colhidos, quer por observação direta, quer através dos resultados das escalas Griffiths e WISC – III, a investigadora aplicou a CIF-CJ, circunscrita aos domínios e funções (variáveis): 1. FUNÇÕESMENTAIS GLOBAIS (b110- Funções da consciência, b114- Funções da orientação no espaço e no tempo, b117 – Funções intelectuais, b122- Funções psicossociais globais, b125- Funções intrapessoais, b126- Funções do temperamento e da personalidade); 2.FUNÇÕES MENTAIS ESPECÌFICAS (b140- funções da atenção, b147- Funções psicomotoras, b152- Funções emocionais, b156- Funções da perceção, b163- Funções cognitivas básicas, b164- Funções cognitivas de nível superior, b167- Funções mentais da linguagem 3. FUNÇÕES DA VOZ E DA FALA (b320- Funções da articulação, b330- Funções da fluência e do ritmo da fala). Numa segunda fase, foi solicitada a colaboração de duas co-investigadoras, com formação específica nas escalas utilizadas e na CIF-CJ, a aplicação da CIF nos mesmos domínios e funções. Estas observadoras não efetuaram observações diretas das crianças envolvidas. • Para efetuar a análise estatística e analisar a relação entre os qualificadores (0 a 4) das variáveis da CIF em estudo (b117, b122, b147, b163, b164, b167, b320 e b330) e os instrumentos psicométricos (escalas de Griffiths e WISC III), que constitui a primeira parte do estudo, recorreu-se à técnica estatística não paramétrica do coeficiente de correlação de Spearman, que quantifica a intensidade e sinal da eventual correlação existente entre as variáveis em estudo. • Para determinar as correlações referentes à segunda parte do estudo, foram utilizados os programas SPSS®, (IBM SPSS Statistics) e Statistica® (StatSoft, Inc., 2011). STATISTICA (data analysis software system, version 10. www.statsoft.com.), tendo-se dado preferência aos gráficos deste último. Resultados 1. Observou-se um predomínio do sexo masculino (relação de 1:1,9); relativamente à idade no momento de avaliação, 242 crianças (68,1%) tinham entre zero e seis anos e, dentro destas, a maioria (189) situava-se entre os três e os seis anos. 2. De acordo com a DSM-IV e DSM-5, 261 (73,4%) crianças apresentavam incapacidade intelectual ligeira. 3. A avaliação da competência intelectual pelas escalas de Ruth Griffiths e WISC III (QI), revelaram correlação negativa predominantemente forte e muito forte (índice de Spearman) com os qualificadores das funções do corpo estudadas (funções mentais, mentais específicas e da voz). Os resultados obtidos pela co-investigadora A foram sobreponíveis aos da investigadora principal. Os resultados obtidos pela co-investigadora B revelaram correlação negativa moderada e forte, correlação inferior à da investigadora principal; Conclusões Os resultados permitem inferir que as escalas de Ruth Griffiths e WISC-III são instrumentos adequados para caracterizar a incapacidade intelectual na CIF-CJ; a concordância inter-observador, moderada, nos qualificadores atribuídos nas funções em análise pela investigadora e co-investigadoras, permite concluir que as escalas de Ruth Griffiths e WISC IIIl são bons instrumentos para caracterizar os qualificadores nos domínios e funções estudados, por diferentes grupos de profissionais ligados à infância. Subsistem dificuldades na diferenciação entre qualificadores, designadamente entre os qualificadores 1 e 2, o que tem necessariamente implicações na elegibilidade das crianças para os apoios preconizados pelo DL 3/2008. ------------------------ ABSTRACT: Main objective • To determine the consistency of the use of assessment tools for intellectual ability - Griffiths and WISC III scales - in the context of domains and qualifiers for the ICF-CY, restricted to the mental functions of the body. Secondary objective • Studying the effectiveness and inter-observer concordance concerning the application of the ICF, based on the data recovered from the assessment made with the mentioned instruments, carried out by two independent observers including their perspective on health, education and social security. Methods • Observational, descriptive, cross-sectional and prospective study. • A convenience sample of 355 children was studied over a period of three years (May 2010 to April 2013), with a pathology in the area of pediatric neurodevelopment – intellectual disability (total of 4000 consultations, including first consultations and revaluations) were observed in the Development Centre (CD) in Hospital de Dona Estefânia (HDE), Centro Hospitalar de Lisboa Central, EPE (CHLC). • Inclusion criteria: children of both sexes aged ≥12 months and years ≤17 and intellectual disability defined according to the criteria in the DSM-IV-TR, DSM 5 and ICD-10. • Exclusion criteria: children with autism; specific language impairment, hyperactivity; attention deficit disorder; severe birth sensory deficits (eg, impaired vision and hearing); amongst other diagnoses for neurodevelopmental disorders. • The study was conducted in two phases: in the first phase the principal investigator collected or updated medical history, clinically observed children requesting additional investigations if she deemed necessary. Psychological evaluation was performed by a single, duly licensed clinical psychologist with extensive experience in the referred scales using the instruments described below. Based on data collected, either by direct observation or through the results of Griffiths scales and WISC - III, the researcher applied the ICF-CY confined to the following fields and functions (variables): 1. GLOBAL MENTAL FUNCTIONS (b110- functions of consciousness, b114- Functions referring to space and time orientation , b117 - intellectual functions, b122- global psychosocial functions, b125- intrapersonal functions, b126- functions related to temperament and personality); 2. SPECIFIC MENTAL FUNCTIONS ( b140- attention functions, b147-psychomotor functions, b152- Emotional functions, b156- perception functions, b163- basic cognitive functions and cognitive functions b164- top level b167- language related mental functions. ) 3. VOICE AND SPEECH FUNCTIONS (b320-articulation functions, b330- fluency and rhythm of speech functions). • In the second phase, two co-investigators, with specific training on the scales used and the ICF-CY have applied the ICF in the domains and functions mentioned above, based on the scales results. These co-investigators did not make any direct observation of the studied children. • To perform the statistical analysis and analyze the relationship between the qualifiers (0-4) of the variables in the ICF study (b117, b122, b147, B163, B164, b167, b320 and B330) and psychometric instruments (Griffiths scale and WISC III), which is the first part of the study, the statistical technique of non-parametric Spearman correlation coefficient was used, which quantifies the strength and sign of the possible correlation between the variables under study. • For submission of correlations related to the second part of the study, SPSS (IBM SPSS) and Statistica (StatSoft, Inc., 2011) programs were used. STATISTICA (data analysis software system, version 10 www.statsoft.com.). Preference was given to graphs computed in Statistica. Results • Male predominated (ratio of 1: 1.9). 242 children (68.1% of the sample) were aged between zero and six years and, among these, the majority (189) was aged largest number between three and six years. • According to the DSM-IV and DSM-5, 261 (73.4%) children had mild intellectual disability. The correlation between the assessment of intellectual competence by Ruth Griffiths scales and WISC III (QI), was predominantly negative strong and very strong correlation with the qualifiers of body functions studied (specific mental functions, mental and voice functions using Spearman index). The levels of correlation obtained by the co-investigatores were in agreeance with the results from the principal investigator. The results obtained by co-investigator B showed moderate to strong negative correlation, levels that were lower to the those registered by the principal investigator; Conclusions These results indicate that Ruth Griffiths and WISC-III scales are adequate tools to characterize intellectual disability in the ICF-CY; moderate inter-observer agreement in the qualifiers assigned the functions under analysis by the researcher and co-researchers, shows that the scales are also good tools to measure CIF qualifyers by diferent technicians with different professional orientations, related to children. However, there are still difficulties in differentiating qualifiers, namely between qualifiers 1/2 and 3/4, which necessarily has implications for the eligibility of children for the state support advocated by the Portuguese Decret Law 3/2008.
