A ocorrência de translocação bacteriana durante a pancreatite aguda tem sido descrita como o principal fator responsável pela ocorrência de infecção pancreática. O objetivo deste trabalho foi determinar o efeito da administração da indometacina na ocorrência de translocação bacteriana e infecção pancreática. Foi utilizado um modelo experimental de pancreatite aguda com taurocolato de sódio 2,5%. Noventa ratos wistar machos foram divididos em três grupos: Sham, Pancreatite e Indometaciana. Foram analisadas, a ocorrência de translocação bacteriana e a incidência de infecção pancreática. A indometacina foi capaz de reduzir a população bacteriana e a incidência de infecção pancreática na pancreatite aguda experimental, no entanto a indometacina não foi capaz de alterar os índices de mortalidade / Increased gut bacterial translocation (BT) in AP has been correlated with pancreatic infection. Thepurpose of this study was to determinate if the BT and pancreatic infection can be reduced in severe AP after Indomethacin administration. An experimental model of severe AP by injection taurocholic acid 2.5%. Ninety male wistar rats were divided in 3 groups: Sham, Pancreatitis, and Indomethacin. We analyzed the occurrence of BT to the pancreas and pancreatic infection with bacterial cultures. Bacterial translocation or bacterial accumulation was not observed in the Sham group. We concluded based in our data that the administration of Indomethacin may reduce the bacterial population in the pancreas and the occurrence of pancreatic infection. Moreover Indomethacin could not reduce the mortality rate in this experimental model

A importância de algumas abordagens psicoterápicas associadas à farmacoterapia no tratamento do Transtorno Depressivo Maior tem sido bastante destacada, no entanto, existem poucos dados sobre a Psicoterapia Psicodramática. O presente estudo comparou 20 pacientes com diagnóstico de TDM em uso de medicamentos antidepressivos e avaliados pela Escala de Depressão de HAM-D17 (escores entre 7 e 20), divididos em dois grupos: dez pacientes do Grupo Psicoterápico (GP) participaram de 4 sessões individuais de psicoterapia psicodramática e 24 de grupo. Dez pacientes do Grupo Controle (GC) não participaram de sessões psicoterápicas. Os dois grupos foram avaliados pela Escala de HAM-D17 e pela Escala de Adequação Social (EAS) no início e final do processo psicoterápico e o GP também foi avaliado pela Análise Sociométrica, fundamentada no método psicodramático. Em comparação ao GC, o GP apresentou uma melhora significativa quanto aos sintomas depressivos e ao funcionamento social, bem como uma expressiva mudança nos aspectos sociométricos investigados / The importance of several psychotherapic approaches associated to pharmacotherapy on the treatment of Major Depressive Disorder has been quite highlighted, although, there is little information as far as Psychodramatic Psychotherapy is concerned. The present study compared 20 patients diagnosed with MDD in use of antidepressant drugs and evaluated with the Hamilton Depression Scale (scores between 7 and 20), divided into two groups as follows: ten of the patients from the Psychotherapic Group (PG) took part in 4 individual psychodramatic psychotherapy sessions and 24 psychodramatic psychotherapy group sessions. Ten of the patients from the Control Group (CG) did not participate in the psychodramatic psychotherapy sessions. Both groups were evaluated with the HAM-D17 Scale and the Social Adjustment Scale - Self Report (SASSR) at the beginning and at the end of the psychotherapic process, and the PG was also evaluated through Sociometric Analysis, based on the psychodramatic method. In comparison to the CG, the PG presented a significant improvement regarding the symptoms of depression and social functioning, as well as an expressive change on the investigated sociometric aspects

Objetivos: Analisar a relevância dos polimorfismos da APOE, -491 e -219 e do LRP na ocorrência de doença de Alzheimer (DA) em indivíduos brasileiros. Metodologia: Realizou-se o estudo em 120 pacientes com DA provável e em 120 controles. Resultados: Houve diferença quanto à freqüência do alelo e4 da APOE, (31% dos pacientes e 10% dos controles). A presença do alelo e2 conferiu efeito protetor. Os polimorfismos das posições -219 e -491 da APOE e do gene LRP não mostraram correlação com DA. Conclusões: O alelo e4 do gene APOE mostrou-se associado a maior risco de DA e o alelo e2 conferiu efeito protetor. Não foi encontrada correlação entre DA e os outros polimorfismos / OBJETIVE: To investigate the role of polymorphisms APOE,-491 and -219 and LRP patients with Alzheimer's disease (AD) and controls in Brazilian individuals.METHODS: One hundred twenty patients and 120 controls were selected for the assessment. RESULTS: The frequency of the e4 allele was 0.31 in patients and 0.10 in controls. The presence of allele e2 was protective factor. No significant difference emerged for the polymorphisms of the localization -219 and -491 of APOE and of the LRP gene. CONCLUSION: These results confirm the relevance of the e4 allele like genetic risk factor and the protective role of the e2 allele in AD. We did not notice any difference in patients and controls for polymorphisms of the LRP and APOE promoter region polymorphism in this study

The present knowledge of factors associated with older adults’ physical activity behaviour is limited. Therefore, this study trialled an innovative physical activity program for older adults, investigating effective recruitment and retention strategies, and exploring the adults’ perceptions of physical activity. A total of 573 subjects were recruited into the quasi-randomised controlled trial, located in 30 intervention and 30 control neighbourhoods in the Perth metropolitan area. The initial response rate was 74% (260/352) in the intervention group and 82% (313/382) in the control group. Self-reported questionnaires administered at three time points (baseline, 3-months, 6-months) measured physical activity levels, personal and demographic information, including perception of financial struggle, proximity to friends, and other psychosocial data. Descriptive statistics, repeated measure analysis of variance, logistic regression and generalised estimating equations were used in the analysis. Qualitative data on the participants’ perceptions of physical activity were collected through one-on-one interviews (n=16). The results showed that: 1. This cost-effective recruitment procedure facilitated the selection of a reasonably representative sample of 65 to 74 year olds from the Perth metropolitan area. Names of 7378 older adults were obtained from the Federal Electoral Roll, then 6401 potential subjects were matched to telephone numbers and phoned with subjects meeting the screening criteria invited to join the program (n = 4209). From this sample, 573 subjects were recruited. More females (63%) than males (37%) were recruited. / The study attracted a greater proportion of ‘obese’ older adults (27%) relative to state averages. 2. Over the intervention period there was a significant increase in participants’ total physical activity of 2.25 hours per week (p >.001). The General Estimating Equation analysis confirmed significant increase in physical activity from baseline to midpoint (p=.002) and to post intervention (p=.0031). Perceptions of financial struggle (p=.020) were positively correlated with physical activity time spent by participants, whereas having friends or acquaintances living nearby (p=.037) had a significant negative correlation with physical activity time. 3. At the end of the intervention, 32% of the intervention group and 25% of the control group had dropped out, resulting in an overall drop out rate of 28%. Most of the attrition occurred in the first 3 months (77%). Characteristics of individuals lost to attrition (n=86, 35%) were compared with program completers (n=162, 65%). Logistic regression analysis showed that those lost to attrition came from areas of lower socio-economic status, were overweight, were less physically active, and had a lower walking self-efficacy score and a higher loneliness score. The results suggest that to improve retention and to avoid potential bias, early assessment of these characteristics should be undertaken to identify individuals at risk of attrition. 4. Based on the finding of this research, future intervention studies should consider: the role of tertiary students as a skilled resource; the use of volunteers to contain costs; the importance of a tailored program; the appropriateness of walking as a form of physical activity for this age group; the enjoyment associated with a walking group; and the usefulness of social support. / This practical program is potentially effective and sustainable for mobilizing physically inactive older people. 5. Qualitative research highlighted the need for older adults to receive more specific information on: the benefits of physical activity; the role of pain management in physical activity; and the concept that involvement in physical activity in younger years leads to involvement when older. The older adults also expressed a desire to engage in less age appropriate activities. These results suggest that the intervention was successful in recruiting older adults into and retaining them in the intervention, documenting a need for early identification of individuals at risk of attrition. The program significantly increased the participants’ weekly mean time for physical activity and identified factors that affect their commitment to physical activity programs. This program was practical and could be used as a model for physical activity programs aimed at older adults.

O Lúpus Eritematoso Sistêmico (LES) é uma doença auto-imune caracterizada pela deposição de imunocomplexos nos tecidos. O clareamento de imunocomplexos está comprometido no LES, contribuindo para a patogênese da nefrite lúpica. Os receptores Fcg (FcgR) participam do clareamento dos imunocomplexos contendo IgG, pois se ligam à porção Fc desta molécula. O FcgRIIa é um receptor que tem dois alelos co-dominantemente expressos, o R131 e o H131, os quais diferem na sua eficiência em se ligar a subclasses de IgG. Células que expressam o homozigoto FcgRIIa-H/H131 são as únicas que se ligam eficientemente a imunocomplexos contendo IgG2, enquanto as que expressam FcgRIIa-R/R131 o fazem de forma menos eficaz. Este polimorfismo tem sido descrito como fator de risco para nefrite lúpica, embora ainda haja controvérsias. O propósito do nosso estudo foi o de analisar, em uma população de nefrite lúpica e em outra de glomerulopatias primárias, a associação entre o genótipo FcgRIIa-R/R131 e a gravidade da doença renal na sua instalação (definida pelo momento da biópsia renal) e ao final do seguimento, bem como possíveis relações com aspectos histológicos renais. A genotipagem do receptor FcgRIIa foi realizada em 76 pacientes com nefrite lúpica e 63 com glomerulopatias primárias através da extração do DNA genômico, seguido de reação de polimerização em cadeia (PCR) e nested PCR, utilizando-se primers específicos. Os pacientes foram avaliados por parâmetros clínicos e laboratoriais. Setenta e um pacientes com nefrite lúpica realizaram biópsia renal, enquanto 5 que já se encontravam em hemodiálise não a realizaram. Pacientes com glomerulonefrite membranoproliferativa, nefropatia da IgA e glomerulonefrite proliferativa mesangial foram agrupados como glomerulopatias proliferativas enquanto os com glomeruloesclerose segmentar e focal, glomerulopatia de lesões mínimas ou glomerulonefrite membranosa foram agrupados como glomerulopatias não proliferativas. O homozigoto FcgRIIa-R/R131 foi mais prevalente no grupo com nefrite lúpica (42,1% de R/R131 e 14,5% de H/H131) em relação ao grupo com glomerulopatias primárias (23,8% de R/R131 e 23,8% de H/H131), dado este estatisticamente significativo (p<0.05). Houve segregação do genótipo FcgRIIa- R/R131 nos pacientes com nefrite lúpica quando comparados aos com glomerulopatias não proliferativas, mas não quando comparados aos com glomerulopatias proliferativas (p<0.05). Não houve diferença na distribuição genotípica do receptor FcgRIIa em relação a classe histológica de nefrite lúpica, tampouco em relação aos que evoluíram ou não para insuficiência renal (Pcr = 1,4mg/dl ao final do seguimento). Um aumento na frequência do genótipo FcgRIIa- R/R131 foi encontrado nos pacientes com nefrite lúpica apresentando níveis mais elevados de FAN (FAN>1/100) e consumo de complemento C3 (p<0,05), mas não naqueles com presença de anticorpos anti-dsDNA ou anti-fosfolípide (p>0,05). Estes achados sugerem que uma distribuição anormal dos genótipos do receptor FcgRIIa com predomínio do homozigoto R/R131 é um fator importante que pode influenciar o desenvolvimento de nefrite lúpica e de glomerulopatias proliferativas. O genótipo FcgRIIa-R/R131 também está relacionado com maior atividade lúpica (FAN>1/100 e consumo de C3) em pacientes brasileiros. / Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by tissue deposition of immune complexes. Immune complex clearance is impaired in SLE, contributing to the pathogenesis of lupus nephritis. Fcg receptors (FcgR) participate in the clearance of the immune complexes containing immunoglobulin G, because they bind the Fc domain of this molecule. The FcgRIIa receptor has two co dominant alleles, R131 and H131. They differ in their efficiency to bind IgG subclasses. Cells expressing the homozygote FcgRIIa-H/H131 are the only ones, which bind efficiently immune complexes containing IgG2, whereas those expressing FcgRIIa-R/R131 do not. This polymorphism has been described as a risk factor for lupus nephritis. However, reports are still controversial. This study aims to establish the role of FcgRIIa polymorphism in the severity and prognosis of lupus nephritis compared to primary glomerulopathies, and whether it is related to histological findings or not. In 76 patients with lupus nephritis and 63 patients with primary glomerulopathies, genotyping of the FcgRIIa receptor was performed with standard PCR, followed by nested PCR using specific primers. The same patients were assessed according to clinical and laboratory patterns. Seventy-one patients with lupus nephritis underwent biopsy, while five did not since they were already under dialysis. Patients diagnosed as membranoproliferative glomerulonephritis, IgA glomerulonephritis and mesangial proliferative glomerulonephritis were grouped as proliferative glomerulopathies, while those with focal segmental glomerulosclerosis, membranous glomerulonephritis and minimal change disease were grouped as nonproliferative glomerulopathies. The homozygous FcgRIIa-R/R131 was more prevalent in lupus nephritis (42,1% being R/R131 and 14,5% H/H131) than in glomerulopathies (23,8% being R/R131 and 23,8% H/H131). These data were statistically significant (p<0.05). A segregation of the FcgRIIa-R/R131 genotype was found in patients with lupus nephritis compared to nonproliferative glomerulopathies, but not when compared to proliferative glomerulopathies (p<0.05). No relation was found between genotype distribution and histological class or renal insufficiency (end-study serum creatinine = 1.4 mg/dl). The genotype R/R131 was more prevalent in lupus nephritis patients presenting complement 3 (C3) consumption and higher antinuclear factor (ANF) titers, but not in those with antidouble- stranded DNA or antiphospholipid antibodies (p>0.05). We concluded that a skewed distribution of the FcgRIIa genotypes with R/R131 predominance may contribute to the development of lupus nephritis and proliferative glomerulopathy. In Brazilian patients, this polymorphism is also related to more intense lupus activity (ANF > 1/100 and C3 consumption).

Estudamos a avaliação clínica de longo termo da resposta de pacientes com diagnóstico precoce de HAM/TSP ao tratamento com metil-prednisolona. Objetivamos pesquisar em relação ao tempo de evolução e apresentação da doença a eficácia deste tratamento. Realizamos o acompanhamento dos pacientes utilizando como parâmetros as escalas de critérios clínicos de Osame e Kurtzke e comparamos com um grupo controle que não recebeu este tipo de tratamento.Os pacientes do grupo experimental e do grupo controle que realizaram fisioterapia mantiveram-se estáveis ou obtiveram melhora de alguns sintomas da doença / We studied the long-term clinical response of patients with early diagnoses of HAM/TSP to treatment with methylprednisolone. The aim was to study this treatment in relation to the time of evolution and presentation of the disease and its effectiveness. The patients were followed using the scales of clinical criteria by Osame and Kurtzke, and compared with a control group of patients who did not receive this treatment type. We observed that patients in the experimental group and the control group, having been followed up with physiotherapy, either remained stable or presented improvement for some symptoms of the disease

This dissertation addresses various methodological and conceptual challenges of prevention programs for preschool children. It focuses on two major topics, (1) methodological guidelines for longitudinal studies in the context of prevention projects, and (2) analyses of emotional development and moral emotions. After a brief introduction to the research questions in Chapter 1, Chapters 2 and 3 address the methodological branch of my research, and Chapters 4 to 6 will analyze several aspects of moral development and moral emotions. In the final Chapter 7, all findings are summarized in view of their application to prevention work in the context of childhood development.

Este estudo avaliou 106 crianças e adolescents com TOC e 44 probandos controle. Estes probandos e seus 465 familiares de primeiro grau foram avaliados por entrevistadores treinados, usando entrevistas semi-estruturadas. Diagnósticos foram determinados pelo DSM-IV, pelo processo de estimativa de diagnóstico. Comparados aos "familiares controle", "familiares caso" tiveram risco significativamente aumentado para TOC (22.7% vs. 0.9%) e tiques (11.6% vs. 1.7%). Houve uma correlação significativa entre as idades de início do TOC nos probandos e seus familiares. Estes dados sugerem que o TOC de início precoce é um transtorno altamente familiar. / The current study examined 106 children and adolescents with OCD and 44 control probands. These probands and their 465 first-degree relatives were assessed by trained interviewers, using standardized semi-structured interviews. Diagnoses were assigned according to DSM-IV criteria, through the best-estimate process. Compared to control relatives, case relatives had higher age-corrected recurrence risks of OCD (22.7% vs. 0.9%) and tics (11.6% vs. 1.7%). There was a significant correlation between the ages of onset of OCD in probands and their affected relatives. These data suggest that childhood onset OCD is a highly familial disorder.
