Abstract: En | Text: En | PDF: En

The correlation between iron distribution in octahedral or tetrahedral sites in synthetic magnetite and zinc spinel ferrites and their catalytic properties were investigated in this work. The zinc-doped nanomagnetites were prepared by co-precipitation method and annealed at 420 °C. X-ray diffraction, UV-Vis, X-ray absorption and 57Fe Mössbauer spectroscopies were used to identify iron sites. The obtained results showed that ZnII replaces the relatively smaller FeIII cation in the tetrahedral sites, increasing the cubic lattice dimension, and this replacement remarkably enhances the catalytic effectiveness of the Zn-spinel ferrite towards the indigo carmine degradation compared to undoped magnetite. The indigo carmine degradation experiments were carried out using photo-Fenton method in which 50 mL of indigo carmine dye aqueous solutions (20 mg L−1, pH 3.0), 20 mg ZnxFe(3-x)O4, and 2.0 mL H2O2 (aqueous solution at 0.028 mol L−1) were placed under UV light at 25 °C. Under these experimental conditions the degradation rate of indigo carmine was superior to 98%.

Abstract: En | Text: En | PDF: En

The ofloxacin (OFLOX) is a second-generation synthetic antibiotic that can be classified as a multifunctional drug, but is a poorly soluble drug, which influences its efficiency. The inclusion complexes of OFLOX with β-cyclodextrin (βCD) or hydroxypropyl-β-cyclodextrin (HPβCD) can improve the chemical characteristics of the drug; however, studies showing the biological activity of these inclusion complexes are still scarce. The present work aimed to investigate the multifunctionality of the OFLOX and their inclusion complexes. Thus, the 1:1 βCD/OFLOX or HPβCD/OFLOX were prepared and analyzed by Fourier transform infrared spectroscopy (FTIR), thermogravimetric and differential thermal analysis (TGA and DTA), 1H nuclear magnetic resonance (NMR) and isothermal titration calorimetry (ITC). The antitumor and antibacterial effects were assessed. The results confirm the formation of the inclusion complexes, which had lower minimum inhibitory concentration (MIC) values, higher cytotoxicity and promoted the apoptosis. The present study showed, for the first time, the promising effects of the inclusion complexes as antitumor, improving the biological activities of the uncomplexed ofloxacin.

Abstract: En | Text: En | PDF: En

Siloxane-poly(methyl methacrylate) (PMMA) hybrid was synthesized based on the sol-gel method and applied to Ti-6Al-4V through dip-coating. The structural feature of the hybrid was subjected to Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TG); its morphological properties were analyzed through scanning electron microscope (SEM), energy dispersive spectrometry (EDS), atomic force microscopy (AFM) and contact angle. The electrochemical behavior and corrosion resistance of both the hybrid coating and the uncoated substrate were investigated based on electrochemical impedance spectroscopy (EIS) and scanning vibrating electrode technique (SVET). Results showed homogeneous coating formation due to the rigid hybrid network formed during polymerization, hydrolysis and condensation reactions. This outcome suggested interaction between the organic (methyl methacrylate (MMA)) and inorganic (tetraethyl orthosilicate (TEOS)) phases, which was favored by the coupling agent (3-(trimethoxysilyl)propyl methacrylate (TMSM)). The S0M (PMMA-SiO2 hybrid Ti-6Al-4V coated alloy) film presented regular topography and adherence to the substrate. Electrochemical simulated body fluid (SBF) tests showed that the hybrid coating presented better barrier properties (168 h of the immersion time) than the uncoated substrate, fact that makes it an interesting material for anti-corrosive applications in biomaterials.

Resumo Objetivo: Este estudo com acompanhamento de longo prazo visou a avaliar o quadro clínico, os achados laboratoriais, o perfil histológico, os tratamentos e os resultados de crianças e adolescentes com hepatite autoimune. Métodos: Foram analisados os prontuários médicos de 828 crianças e adolescentes com HAI. Foi usado um questionário para coletar os dados anônimos sobre o quadro clínico, os achados bioquímicos e histológicos e os tratamentos. Resultados: De todos os pacientes, 89,6% tinham hepatite autoimune-1 e 10,4% hepatite autoimune-2. O sexo feminino foi predominante nos dois grupos. A idade média no início dos sintomas foi 111,5 (6; 210) e 53,5 (8; 165) meses nos pacientes com hepatite autoimune-1 e hepatite autoimune-2, respectivamente. Foi observado início clínico agudo em 56,1% e 58,8% e sintomas insidiosos em 43,9% e 41,2% dos pacientes com hepatite autoimune-1 e hepatite autoimune-2, respectivamente. A probabilidade de insuficiência hepática foi 1,6 vezes maior para hepatite autoimune-2; 3,6% e 10,6% dos pacientes com hepatite autoimune-1 e hepatite autoimune-2, respectivamente, apresentaram insuficiência hepática fulminante; o risco foi 3,1 vezes maior para hepatite autoimune-2. Os níveis de gamaglobulina e imunoglobulina G foram significativamente maiores nos pacientes com hepatite autoimune-1, ao passo que os níveis de imunoglobulina A e C3 foram menores em pacientes com hepatite autoimune-2; 22,4% dos pacientes apresentaram cirrose e a remissão bioquímica foi atingida em 76,2%. A taxa de sobrevida atuarial foi de 93,0%. Um total de 4,6% pacientes foram submetidos a transplante de fígado e 6,9% morreram (hepatite autoimune-1: 7,5%; hepatite autoimune-2: 2,4%). Conclusões: Nesta grande série clínica de crianças e adolescentes brasileiros, a hepatite autoimune-1 foi mais frequente e os pacientes com hepatite autoimune-2 mostraram maiores taxas de remissão da doença com respostas mais rápidas aos tratamentos. Os pacientes com hepatite autoimune-1 apresentaram maior risco de óbito.

Abstract Objective: This large study with a long-term follow-up aimed to evaluate the clinical presentation, laboratory findings, histological profile, treatments, and outcomes of children and adolescents with autoimmune hepatitis. Methods: The medical records of 828 children and adolescents with autoimmune hepatitis were reviewed. A questionnaire was used to collect anonymous data on clinical presentation, biochemical and histological findings, and treatments. Results: Of all patients, 89.6% had autoimmune hepatitis-1 and 10.4% had autoimmune hepatitis-2. The female sex was predominant in both groups. The median age at symptom onset was 111.5 (6; 210) and 53.5 (8; 165) months in the patients with autoimmune hepatitis 1 and autoimmune hepatitis-2, respectively. Acute clinical onset was observed in 56.1% and 58.8% and insidious symptoms in 43.9% and 41.2% of the patients with autoimmune hepatitis-1 and autoimmune hepatitis-2, respectively. The risk of hepatic failure was 1.6-fold higher for autoimmune hepatitis-2. Fulminant hepatic failure occurred in 3.6% and 10.6% of the patients with autoimmune hepatitis-1 and autoimmune hepatitis-2, respectively; the risk was 3.1-fold higher for autoimmune hepatitis-2. The gamma globulin and immunoglobulin G levels were significantly higher in autoimmune hepatitis-1, while the immunoglobulin A and C3 levels were lower in autoimmune hepatitis-2. Cirrhosis was observed in 22.4% of the patients; biochemical remission was achieved in 76.2%. The actuarial survival rate was 93.0%. A total of 4.6% underwent liver transplantation, and 6.9% died (autoimmune hepatitis-1: 7.5%; autoimmune hepatitis-2: 2.4%). Conclusions: In this large clinical series of Brazilian children and adolescents, autoimmune hepatitis-1 was more frequent, and patients with autoimmune hepatitis-2 exhibited higher disease remission rates with earlier response to treatment. Patients with autoimmune hepatitis-1 had a higher risk of death.

ABSTRACT Objective Our aim was to describe the distribution of selected biomarkers according to age and sex, adjusted for HOMA-IR and adiposity, in a subset of middle-aged individuals of Brazilian Longitudinal Study of Adult Health-ELSA without diabetes mellitus or CVD. Subjects and methods This cross-sectional study was conducted in 998 participants of the ELSA-Brasil without diabetes and/or cardiovascular disease. In addition to the traditional risk factors, several biomarkers concentrations were compared according to sex, age groups (35-44; 45-54 yrs) and HOMA-IR tertiles. Linear regression was used to examine independent associations of sex and age with selected novel biomarkers, adjusted for body adiposity and HOMA-IR. Results Fifty-five percent were women. Men had higher mean values of body mass index, waist circumference, blood pressure, plasma glucose, HOMA-IR, worse lipid profile and higher E-selectin and lower leptin concentrations than women; while women had higher levels of HDL-cholesterol and leptin than men. Mean values of waist circumference, systolic BP, plasma glucose and apolipoprotein B (Apo B) increased with age in both sexes. Leptin and E-selectin concentrations increased across HOMA-IR tertiles. Independent associations of Apo B with age were found only in male sex, while of leptin with body mass index and HOMA-IR, and of E-selectin with HOMA-IR in both sexes. Conclusions In conclusion, our data indicate age, sex, adiposity and, consequently, insulin resistance, influence circulating levels of Apo B, leptin and E-selectin, suggesting that those aspects should be taken into consideration when assessing these parameters for research or clinical purposes in individuals at relatively low cardiometabolic risk.

Resumo Apresenta-se uma síntese atualizada de informações sobre algas no Brasil objetivando refinar os dados reunidos até o presente, bem como avaliar os avanços sobre o conhecimento da diversidade de algas no país desde a publicação do Catálogo de Plantas e Fungos do Brasil. Os resultados de 2015 mostraram um acréscimo de 1.250 espécies (35.7%) a um total de 4.747 em relação a 2010. As classes mais diversas em número de espécies foram Bacillariophyceae, Conjugatophyceae, Florideophyceae, Cyanophyceae, Dinophyceae e Euglenophyceae. Bacillariophyceae e Cyanophyceae tiveram o maior acréscimo de espécies no intervalo de cinco anos. A região Sudeste e Sul foram as mais diversas, porém, as regiões Nordeste com os estados do Piauí e Sergipe e Centro-Oeste com os estados de Mato Grosso, Goiás e Distrito Federal destacaram-se no cenário da biodiversidade nacional. Apesar da escassez de taxonomistas e da infraestrutura limitada, os resultados obtidos evidenciaram um avanço significativo no conhecimento da diversidade de algas no país nesse período de cinco anos, iniciando uma mudança quanto as diferenças geográficas regionais.

Abstract An updated synthesis of cyanobacteria and algae information is presented for Brazil aiming to refine the data gathered to date and evaluate the progress of the biodiversity knowledge about these organisms in the country since the publication of the Catálogo de Plantas e Fungos do Brasil. The results of 2015 showed an increase of 1,250 species (35.7%) when compared to 2010, reaching a total of 4,747 species. The most diverse classes in species number were the Bacillariophyceae, Conjugatophyceae, Florideophyceae, Cyanophyceae, Dinophyceae and Euglenophyceae. Bacillariophyceae and Cyanophyceae had the highest increase in species number in the five-year interval. The Southeast and South regions were the most diverse, however, the Northeast, with the states of Piauí and Sergipe, and the Central-west region, with Mato Grosso, Goiás and Distrito Federal, also stood out in the national algal biodiversity scenario. Despite the shortage of taxonomists and limited infrastructure, the results showed a significant improvement in the knowledge regarding the diversity of cyanobacteria and algae in the country during the study period, starting to even out regional geographical differences caused by subsampling.

O envelhecimento é um processo biológico caracterizado por progressivos danos de estrutura e função dos sistemas orgânicos. No trato gastrointestinal, pode acometer o sistema nervoso entérico, o qual possui funções importantes na digestão e absorção de nutrientes causando aceleração do trânsito intestinal, reduzindo assim a sua função de absorção. A restrição calórica tem sido utilizada em vários estudos com a intenção de retardar os efeitos deletérios do envelhecimento. Este estudo teve como objetivo avaliar os efeitos da restrição calórica sobre os neurônios mioentéricos do íleo de 30 ratos durante o processo de envelhecimento. 30 ratos wistar foram agrupados da seguinte forma: GI (animais de 6 meses alimentados com dieta normal), GII (animais de 18 meses alimentados com dieta normal) e GIII (animais com idade de 18 meses com 31% de restrição calórica). Os ratos do grupo GI aos seis meses de idade e os animais do grupo GII e GIII foram eutanasiados após o período experimental de 12 meses, o íleo de todos os grupos foram coletados, medidos e processados pelas técnicas NADPH-d e acetilcolinesterase. A análise quantitativa dos neurônios revelou que o envelhecimento promove o aumento de neurônios mioentéricos NADPH-dp e reduz a população neuronal Acetilcolinesterase positiva. Entretanto, na área do perfil celular, não foram observadas diferenças significativas entre os grupos. A restrição calórica foi eficiente e pode ser utilizada como forma preventiva, uma vez que minimiza as alterações quantitativas associadas ao envelhecimento no plexo mioentérico do íleo.

Aging is a biologic process characterized by progressive damage of structures and functions of organic systems. In gastrointestinal tract, it can involve enteric nervous system, which plays an important role in digestion and absorption of nutrients, causing hastening of intestinal transit thus reducing its absorptive function. Caloric restriction has been used in several studies with the intention of delaying deleterious effects of aging. This study aimed to evaluate the effects of caloric restriction on myenteric neurons of ileum by aging in rats. 30 Wistar rats were grouped as follows: GI (animals aged 6 months fed with normal diet), GII (animals aged 18 months fed with normal diet) and GIII (animals aged 18 months subject to 31% of caloric restriction). The rats of the GI group were euthanized at 6 months of age and after experimental period of 12 months animals of the group GII and GIII were euthanized, the ileum of all groups were collected, measured and processed by NADPH-dp and Acetylcholinesterase. Quantitative analysis of neurons revealed that aging promotes the increasing of myenteric neurons NADPH-dp and reduces Acetylcholinesterase neuronal population. However, in the cellular profile area, were not observed significant differences between the groups. The caloric restriction has been efficient and can be used preventively because it minimizes quantitative changes associated with aging on ileum myenteric plexuses.

OBJETIVO: Investigar a associação entre consumo de alimentos embutidos e obesidade generalizada, abdominal e generalizada com abdominal em nipo-brasileiros de Bauru, SP. SUJEITOS E MÉTODOS: Quatrocentos e quarenta e três mulheres e 329 homens nipo-brasileiros não miscigenados (≥ 30 anos) foram avaliados em estudo transversal de base populacional. Para o diagnóstico de obesidade, foram empregados os critérios da Organização Mundial da Saúde para asiáticos. A ingestão de alimentos foi avaliada por meio de questionário de frequência alimentar validado. A ingestão foi estratificada em terços para análise. RESULTADOS: Nos homens, a ingestão de colesterol e alimentos embutidos mostrou-se positivamente associada à obesidade generalizada com abdominal quando o primeiro terço de ingestão foi comparado ao último, após ajustes (OR 2,97; IC95% 1,13-7,78). Em mulheres, somente o grupo das carnes vermelhas associou-se à obesidade geral com abdominal após ajustes (OR 0,47; IC95% 0,23-0,96). CONCLUSÃO: Ingestão elevada de alimentos embutidos associou-se à obesidade generalizada com adiposidade abdominal em homens nipo-brasileiros, mas não em mulheres.

OBJECTIVE: The aim of this study was to investigate the association between the consumption of processed meat with overall, abdominal, and overall with abdominal obesity in a Japanese-Brazilian population, which is known to be at cardiometabolic risk. SUBJECTS AND METHODS: A total of 329 men and 443 women aged ≥ 30 years were evaluated in a cross-sectional population-based survey. Diagnosis of overall obesity and abdominal obesity were based on the World Health Organization (WHO) criteria for Asians. Food intake was assessed by a validated food frequency questionaire. RESULTS: In men, processed meat intake was positively associated with overall with abdominal obesity (OR 2.97; 95%CI 1.13-7.78) after adjustment. In women, only the red meat group was associated with overall with abdominal obesity after adjustment (OR 0.47, 95%CI 0.23-0.96). CONCLUSION: Our results showed that high intakes of processed meats were associated with overall with abdominal obesity in male Japanese-Brazilians, but not in females.

O objetivo deste estudo foi descrever a metodologia e a implementação de programa de mudanças no estilo de vida em indivíduos de risco cardiometabólico, usuários da rede pública de saúde em São Paulo. O Programa de Prevenção de Diabetes Mellitus (PDM) visa à melhora do quadro metabólico global de indivíduos com pré-diabetes ou síndrome metabólica sem diabetes, tendo como metas redução mínima de 5% do peso corporal inicial, consumo > 20 g de fibras alimentares e < 10% de gorduras saturadas por dia, além de prática > 150 minutos de atividade física por semana. A primeira edição do PDM apresentou duração de 18 meses e contou com equipe interdisciplinar (endocrinologista, psicóloga, nutricionista e educador físico) para o planejamento e realização de sessões em grupo com os participantes. A estrutura e a sistemática das sessões foram planejadas utilizando abordagem psicoeducativa para facilitar o processo de mudança de hábitos de vida. Com base na experiência com o PDM, algumas reflexões e recomendações são apontadas. Este estudo aponta caminhos para que profissionais da saúde possam juntos adaptar programas locais para promoção de hábitos de vida saudáveis, atuando sob uma nova perspectiva.

The objective this study was to describe the methodology and implementation of lifestyle change program in individuals at cardiometabolic risk seen at the public health system in Sao Paulo. The Programa de Prevenção de Diabetes Mellitus (PDM) aims at improving the overall metabolic profile of individuals with prediabetes or metabolic syndrome without diabetes; its goals were > 5% weight loss, dietary fiber intake > 20 g per day, saturated fatty acids intake < 10% per day, and > 150 minutes of physical activity per week. The first edition of the PDM lasted 18 months and involved an interdisciplinary team (endocrinologist, psychologist, nutritionist, and physical educator) to plan and conduct group sessions with the participants. The structure and systematic of the sessions were planned using a psychoeducative approach in order to facilitate the process of lifestyle changes. Based on the Experience with the PDM, some reflections and recommendations are made. This study may indicate ways for health professionals to tailor local care conditions and promote a healthy lifestyle, working with a new perspective.

OBJETIVOS: Avaliar a qualidade de vida de pacientes obesos do sistema público de saúde brasileiro antes e após cirurgia bariátrica e a adequação do questionário Moorehead-Ardelt II (M-A-QoLQII) em relação ao SF-36. SUJEITOS E MÉTODOS: Quarenta e um pacientes obesos graves em lista de espera e 84 submetidos à cirurgia bariátrica foram incluídos. Correlações foram testadas e confiabilidade determinada pelo coeficiente de Cronbach. RESULTADOS: O IMC diferiu entre os grupos pré- e pós-cirurgia (52,3 ± 8,3 kg/m² vs. 32,5 ± 6,4 kg/m², p < 0,001). O último apresentou melhores escores nos domínios do SF-36 que o pré-cirurgia. As categorias do SF-36 e M-A-QoLQII se correlacionaram (r = 0,53; 0,49; 0,47 para vitalidade, saúde mental e saúde geral, p 0,001). Na regressão logística, idade, IMC prévio e excesso de peso perdido associaram-se independentemente à capacidade funcional. CONCLUSÕES: Resultados da cirurgia bariátrica em centro de saúde público brasileiro foram promissores. O M-A-QoLQII representa ferramenta útil para avaliar seus resultados, inclusive a QV.

OBJECTIVES: To assess QoL of obese patients in the Brazilian public healthcare system, before and after bariatric surgery, and to determine the appropriateness of the Moorehead-Ardelt Questionnaire II (M-A-QoLQII) compared with the Short-Form Health Survey (SF-36). SUBJECTS AND METHODS: Forty-one severe obese patients in a waiting-list, and 84 patients who underwent bariatric surgery were included. Correlations were tested and reliability determined by the Cronbach's coefficient. RESULTS: BMI differed between the pre- and post-surgery groups (52.3 ± 8.3 kg/m² vs. 32.5 ± 6.4 kg/m², p < 0.001). The latter showed better scores in the SF-36 domains than in the pre-surgery. SF-36 and M-A-QoLQII categories were correlated (r = 0.53, 0.49 and 0.47, for vitality, mental health, and general health domains, p < 0.001). In the logistic regression, age, previous BMI, and loss of excess weight were associated with functional capacity. CONCLUSIONS: The outcomes of bariatric surgery obtained in a Brazilian public healthcare center were successful. M-A-QoLII represents a useful tool to assess surgery outcomes, including QoL.

OBJETIVO: Descrever o hábito alimentar de nipo-brasileiros com e sem doença macrovascular (DMV). MÉTODOS: Definiu-se DMV, para 1.165 nipo-brasileiros, a partir de escores atribuídos ao histórico de saúde, eletrocardiograma e valores do índice tornozelo-braquial. Determinou-se o consumo alimentar habitual por meio de Questionário de Frequência do Consumo de Alimentos. RESULTADOS: A porcentagem de casos confirmados com DMV foi de 3,2%, sendo semelhante entre os sexos. Observou-se, de forma estatisticamente significante, maior frequência de indivíduos com DMV (confirmados ou suspeitos) entre aqueles de primeira geração, com idade > 60 anos, tabagistas, com hipertensão arterial, hipertrigliceridemia e diabetes. Nipo-brasileiros com DMV (confirmados ou suspeitos) apresentaram menor perímetro do quadril e maior idade, pressão arterial sistólica, triglicérides, glicemia, consumo de alimentos fonte de ferro e menor fonte de fibras de grãos. Encontrou-se diferença estatisticamente significante apenas para o consumo de gordura saturada (análise bruta: segundo terço versus primeiro terço). CONCLUSÕES: programas de educação nutricional devem ser incentivados neste grupo com alta prevalência de doenças crônicas não transmissíveis.

OBJECTIVE: To describe the food intake of Japanese-Brazilians with and without macrovascular disease (MVD). METHODS: MVD was defined, for 1,165 Japanese-Brazilians, by scores attributed to the health historical, electrocardiogram and ankle-brachial index values. The usual dietary intake was determined using a food frequency questionnaire. RESULTS: The MVD prevalence was of 3.2%, being similar among genders. Statistically higher frequencies of individuals with MVD were observed among those of first generation, with age > 60 years, tobacco user, with hypertension, hypertriglyceridemia and diabetes. Subjects with MVD were older, with smaller hip circumference, and higher systolic blood pressure levels, triglycerides and glycemia concentration; they informed higher consumption of iron source food and smaller of grains fibers. Statistically significant difference was found to saturated fat (crude analysis: second tercile versus first tercile). CONCLUSIONS: Programs of nutritional education should be stimulated in this group with high prevalence of non-communicable chronic diseases.

Populações migrantes representam oportunidade para se investigar a contribuição de fatores ambientais na gênese da obesidade e suas comorbidades. Em 1993, o Japanese-Brazilian Diabetes Study Group estudou a prevalência de diabetes e doenças associadas em nipo-brasileiros residentes em Bauru, SP. Utilizando critérios específicos para asiáticos, 22,4% dos nipo-brasileiros foram caracterizados como portadores de excesso de peso nessa primeira fase do estudo. Na segunda fase, em 2000, essa prevalência subiu para 44,2%, e 50,3% apresentavam obesidade central. Essa população também apresentava alta prevalência de diabetes tipo 2, hipertensão e dislipidemia, componentes da síndrome metabólica. O JBDS Group também mostrou a associação entre hábitos ocidentais, especialmente alimentação rica em gordura saturada, e a ocorrência de síndrome metabólica. Em 2005, motivado por esses achados, o JBDS Group iniciou a terceira fase do estudo que constou de programa de intervenção com base em orientação para dieta saudável e prática de atividade física, utilizando recursos factíveis em termos de saúde pública no Brasil. Após um ano de intervenção, o JBDS Group observou diminuição nos parâmetros antropométricos, pressão arterial e níveis de glicemia e colesterol. Tempo de acompanhamento maior é necessário para avaliar a persistência desses benefícios e o impacto deles no risco de desenvolver diabetes e eventos cardiovasculares.

Migrant populations represent a good opportunity to investigate the role of environmental factors for the genesis of obesity and its comorbidities. The Japanese-Brazilian Diabetes Study Group studied the prevalence of diabetes and related disorders in Japanese-Brazilians from Bauru, SP, in 1993. Using specific criteria for Asian, 22.4% of the Japanese-Brazilians were found as having overweight in this first phase of the study. In the second phase, in 2000, this prevalence increased to 44.2% and 50.3% had central obesity. This population also had high prevalence of type 2 diabetes, hypertension and dyslipidemia, components of the metabolic syndrome. The JBDS Group also showed the association between Occidentalized habits, mainly a rich saturated-fat-diet, and the occurrence of the metabolic syndrome. In 2005, motivated by these findings, the JBDS Group started the third phase of the study which was an intervention program based on healthy diet and physical activity recommendations, using resources that could be feasible in terms of public health in Brazil. After one year-intervention program, the JBDS Group observed a decrease in anthropometric parameters, blood pressure and plasma glucose and cholesterol levels. It will be necessary a longer follow-up to evaluate the maintainance of these benefits and their impact in the risk development of diabetes and cardiovascular events.

OBJETIVO: Analisar a idade na cirurgia de crianças com atresia biliar e a sobrevida sem necessidade de transplante de fígado. O estudo foi realizado no Hospital de Clínicas de Porto Alegre. MÉTODOS: Foram revisados os prontuários dos pacientes operados entre 1982 e 2007, residentes no Rio Grande do Sul. RESULTADOS: Dos 112 casos estudados de crianças com atresia biliar, 38 (33,9%) ocorreram de 1982 a 1989, 46 (41,1%) de 1990 a 1999 e 28 (25,0%) a partir de 2000. Em 12 (10,7%) casos, não foi realizada a portoenterostomia. A idade na cirurgia variou de 25 a 297 dias (mediana: 80,5; IIQ25-75: 61,3-109,0 dias); em 20,5% dos casos, a idade das crianças foi menor do que 60 dias. Não houve diferença na idade, no momento do diagnóstico, entre as 3 décadas. Os pacientes do interior do estado (mediana: 87,0; IIQ25-75: 69,0-115,0 dias) foram encaminhados significativamente (p = 0,007) mais tarde do que os da região metropolitana de Porto Alegre (RS) (mediana: 68,0; IIQ25-75: 55,5-98,0 dias). A proporção de pacientes com menos de 60 dias foi significativamente menor (p = 0,013) nos oriundos do interior. A sobrevida com fígado nativo do total dos pacientes foi de 46,2% em 2 anos, diminuindo progressivamente até 15,3% em 20 anos. Os pacientes operados com menos de 60 dias tiveram maior sobrevida com fígado nativo (log rank < 0,0001). CONCLUSÕES: A portoenterostomia se manteve tardia nos últimos 25 anos, e esse atraso determinou menor tempo de sobrevida com fígado nativo nos pacientes com atresia biliar.

OBJECTIVE: To analyze the age at surgery for children with biliary atresia and their survival periods without need for liver transplantation. The study was performed at Hospital de Clínicas de Porto Alegre, in Porto Alegre, state of Rio Grande do Sul, Brazil. METHODS: The medical records of patients operated between 1982 and 2007 who were residents of the state of Rio Grande do Sul were reviewed. RESULTS: Of the 112 cases of children with biliary atresia studied, 38 (33.9%) occurred between 1982 and 1989, 46 (41.1%) between 1990 and 1999 and 28 (25.0%) after 2000. Portoenterostomy was not performed for 12 cases (10.7%). Age at surgery ranged from 25 to 297 days (median: 80.5; IQR25-75: 61.3-109.0 days); for 20.5% of cases, the age was below 60 days. There was no age difference at diagnosis for the three decades in the study. Patients from the countryside (median: 87.0; IQR25-75: 69.0-115.0 days) were referred significantly later (p = 0.007) than those living in Porto Alegre and the metropolitan area (median: 68.0; IQR25-75: 55.5-98.0 days). The ratio of patients younger than 60 days was significantly lower (p = 0.013) for those from the countryside. Survival periods with native liver for all patients was 46.2% in 2 years, falling continuously until reaching 15.3% in 20 years. Patients operated before reaching 60 days of age had longer survival periods with native livers (log rank < 0.0001). CONCLUSIONS: Late performance of portoenterostomy was a constant in the past 25 years, and this delay led to shorter survival periods with native livers for biliary atresia patients.

Alta prevalência de diabetes em população nipo-brasileira de Bauru/SP foi previamente relatada. Visando a complementar a avaliação do risco cardiometabólico, este estudo analisou distúrbios no perfil lipídico de 1.330 nipo-brasileiros (46% homens) > 30 anos. Definiu-se hipercolesterolemia por níveis de colesterol total > 240 mg/dL; hipertrigliceridemia por valores > 150 mg/dL e HDL-colesterol baixo por valores < 40 mg/dL e < 50 mg/dL para homens e mulheres, respectivamente. A prevalência desses distúrbios foi comparada pelo qui-quadrado, estratificando-se por sexos e categorias glicêmicas. As médias dos lipídeos e lipoproteínas foram comparadas entre sexos pelo teste t de Student. A prevalência de hipertrigliceridemia foi de 66,0% (IC95%:63,5 - 68,5%), sendo mais comum em homens e aumentando com a piora da categoria glicêmica; a trigliceridemia média foi 235,7 ± 196,3 mg/dL. A prevalência de hipercolesterolemia foi 24,4% (IC95%:22,1 - 26,7%); HDL-C baixo foi observado em 43,0% (IC95%:39,4 - 46,6%] das mulheres e 17,5% (IC95%:14,5 - 20,5%) dos homens, porém a razão colesterol total/HDL-C foi menor em mulheres (4,23 ± 0,68 vs. 4,40 ± 0,73; p < 0,001). Em nipo-brasileiros, a hipertrigliceridemia é a anormalidade lipídica mais comum, em concordância com a elevada prevalência de diabetes. Os homens apresentaram pior perfil lipídico que as mulheres. Sugere-se que hábitos de vida ocidental possam estar deteriorando a saúde desses indivíduos.

High prevalence of diabetes has been previously reported in Japanese-Brazilians. In an attempt to better estimate the cardiometabolic risk, this study evaluated lipid disorders in 1,330 Japanese-Brazilians (46% men) aged >30 years. Hypercholesterolemia was defined as serum cholesterol > 240 mg/dL, hypertriglyceridemia as values > 150 mg/dL and low-HDL-C as values <40 mg/dL and <50 mg/dl for men and women respectively. The prevalence of dyslipidemias was compared by the chi-square test between gender and glycemic category. Mean and Standard Deviation of lipids and lipoproteins were compared by the Student t-Test between gender. Hypertriglyceridemia was detected in 66.0% [95% CI: 63.5-68.5] of the population, being more common in men and increasing with deterioration of glucose metabolism. Mean level of triglycerides was 235.7±196.3 mg/dL. The prevalence of hypercholesterolemia was 24.4% [95% CI: 22.1- 26.7]. Low HDL-C was observed in 17.5% [95% CI: 14.5-20.5] of men and 43.0% [95% CI: 39.4- 46.6] of women but total / HDL-cholesterol ratio was lower in women (4.23 ± 0.68 vs. 4.40 ± 0.73, p<0.001). In Japanese-Brazilians, hypertriglyceridemia is the commonest dyslipidemia, in agreement with the high prevalence of diabetes. Men showed a worse lipid profile than women; it was suggested that the Western diet and living habits could be deteriorating their health.
