ABSTRACT

Objective: To identify an association between prematurity and the nutritional, metabolic and inflammatory aspects of pre-school children. Methods: This was a case-control study with 32 preterm children and 32 full-term children. A nutritional diagnosis was obtained through the anthropometric indexes of height/age (H/A) and BMI/Age (BMI/A) using the WHO AnthroPlus® program. Metabolic assessment was performed through the levels of fasting glucose, fasting insulin, total cholesterol, triacylglycerides, high-density lipoprotein and low-density lipoprotein. The inflammatory profile was identified through the serum levels of interleukin 6 (IL-6) and C-reactive protein (CRP). Results: The assessment age of preterm children was 81 months ± 23.8. A shorter gestation time was associated with an increased waist circumference (p=0.035), and total cholesterol levels (p=0.031), and tended toward an association with higher interleukin 6 levels (p=0.062). Waist circumference was associated with higher adiposity (p=0.003) and with increased blood pressure (p=0.010). Conclusion: Preterm birth was related to increased levels of total serum cholesterol and increased waist circumference, thereby suggesting a higher risk of future cardiovascular events. No association was observed between gestational age and birth weight with other nutritional, metabolic or inflammatory aspects in the pre-school children assessed.(AU)

ABSTRACT

INTRODUÇÃO: A desnutrição presente em portadores de cardiopatias congênitas eleva o risco de complicações pós-operatórias. A contagem de linfócitos sofrem interferência do estado nutricional e a hipoalbuminemia leva a maior risco de morbimortaliadade hospitalar. A triagem nutricional STRONGKids identifica o risco nutricional permitindo intervenção precoce e adequada. OBJETIVO: Avaliar o risco nutricional de pacientes pediátricos submetidos a cirurgias cardíacas por diferentes métodos. MÉTODOS: Estudo longitudinal, realizado entre março e outubro de 2015 com 49 crianças e adolescentes entre 1 mês e 15 anos, internados para realização de cirurgia cardíaca. Para os dados bioquímicos consideraram-se contagem total de linfócitos e níveis séricos de albumina. Para o risco nutricional aplicou-se a ferramenta STRONGKids. Antropometria clássica (peso, estatura, prega cutânea triciptal e circunferência braquial) e diagnóstico nutricional pelos indicadores antropométricos (OMS,2005/2006) foram realizados. A análise estatística foi realizada pelo programa SPSS versão 22.0. Os resultados foram significativos quando p < 0,05. RESULTADOS E DISCUSSÃO: A mediana da idade foi de 37 meses, (2 a 197 meses; IQ: 54, 3 meses), sendo 65,3% menores de 60 meses. A contagem total de linfócitos e os níveis séricos de albumina não refletiram a condição nutricional dos indivíduos avaliados. A maioria dos pacientes desnutridos (38,5%) apresentou níveis normais de albumina sérica (p = 0,411), porém sabe-se que a albumina não é bom marcador do estado nutricional por baixa sensibilidade na fase aguda da desnutrição. Os pacientes desnutridos não apresentaram depleção segundo a contagem total de linfócitos (p = 0,061). O escore de triagem apresentou relação positiva com a antropometria da admissão (p = 0,004). CONCLUSÃO:A não associação entre concentração de albumina e de linfócitos com o estado nutricional pela antropometria leva a crer que esses métodos bioquímicos são pouco práticos para esse fim. A triagem STRONGKids não diferenciou o risco nutricional na população avaliada. Mais estudos devem ser realizados para melhor acompanhar esse grupo populacional


INTRODUCTION: Malnutrition in patients with congenital heart disease increases the risk of postoperative compli cations. The lymphocyte count is influenced by nutri tional status and hypoalbuminemia leads to a higher risk of hospital morbidity and mortality. STRONGKids nutritional screening identifies nutritional risk by allowing early and adequate intervention. OBJECTIVE: To evaluate the nutritional risk of pediatric patients submitted to cardiac surgeries by different methods. METHODS: A longitudinal study was conducted between March and October 2015 with 49 children and adolescents between 1 month and 15 years of age hospitalized for cardiac surgery. For biochemical data, total lymphocyte counts and serum albumin levels were considered. For the nutritional risk the STRONGKids tool was applied. Classical anthropometry (weight, height, triceps skinfold and brachial circumference) and nutritional diagnosis by anthropometric indicators (WHO, 2005/2006) were performed. Statistical analysis was performed by SPSS software version 22.0. The results were significant when p <0.05. RESULTS AND DISCUSSION: The median age was 37 months, (2 to 197 months, IQ: 54, 3 months), being 65.3% younger than 60 months. The total lymphocyte count and serum albumin levels did not reflect the nutritional status of the individuals evaluated. Most malnourished patients (38.5%) had normal levels of serum albumin (p = 0.411), but it is known that albumin is not a good marker of nutritional status due to low sensitivity in the acute phase of malnutrition. Malnourished patients did not present depletion according to the total lymphocyte count (p = 0.061). The screening score presented a positive relation with admission anthropometry (p = 0.004). CONCLUSION: The non-association between concentration of albumin and lymphocytes with nutritional status by anthropometry leads us to believe that these biochemical methods are impractical for this purpose. The STRONGKids screening did not differentiate nutritional risk in the evaluated population. Further studies should be performed to better accompany this population group

ABSTRACT

Ocimum selloi, a traditional medicinal plant from Brazil, is sold in open-air markets at Rio de Janeiro State. Hesperozygis myrtoides is a very aromatic small bush found in the State of Minas Gerais, Brazil, growing at an altitude of 1800m. The chemical composition of both essential oils was analyzed as well as their antimicrobial activity against fungi and bacteria. For all specimens of Ocimum selloi obtained at open-air markets, methylchavicol was major compound found (93.6% to 97.6%) in their essential oils. The major compounds identified in the oil of H. myrtoides were pulegone (44.4%), isomenthone (32.7%), and limonene (3.5%). Both oils displayed antimicrobial activity against all tested microorganisms but Candida albicans was the most susceptible one. Combinations of the two oils in different proportions were tested to verify their antimicrobial effect against C. albicans, which, however, was not modified in any of the concentrations tested. The minimum inhibitory concentration (MIC) was determined to confirm the antimicrobial activity against C. albicans as well as other clinical isolates (C. glabrata, C. krusei, C. parapsilosis and C. tropicalis).

ABSTRACT

PURPOSE: To evaluate the clinical and epidemiological risk factors for endometrial cancer in postmenopausal women with endometrial polyps, as well as the genetic polymorphism of the progesterone receptor (PROGINS). METHODS: A case-control study was designed with 160 postmenopausal women with endometrial polyps, compared to a normal Control Group of 400 postmenopausal women. The genotyping of PROGINS polymorphism was determined by the polymerase chain reaction. Clinical and epidemiological data were compared between benign endometrial polyps and 118 of the control subjects. Variables were also compared with regard to benign and malignant endometrial polyps. RESULTS: Comparison of the epidemiological variables between groups showed a significant difference for age, ethnicity, time since menopause, parity, tamoxifen use, hypertension and breast cancer, all of them more prevalent in the polyp group. After adjustment for age, statistical significance remained only for parity (OR=1.1), hypertension (OR=2.2) and breast cancer (OR=14.4). There were six cases of malignant polyps (3.7%). The frequency of bleeding was 23.4% for benign polyps and 100% for malignant polyps, with large polyps being detected in 54.6% of the benign cases and in 100 of the malignnat ones. The frequency of arterial hypertension was 54.5% for benign polyps and 83.3% for the malignant ones. The frequency of PROGINS T1/T1, T1/T2 and T2/T2 polymorphism was 79.9%, 19.5% and 0.6%, respectively, for the polyp group, and 78.8%, 20.8% and 0.5% for the Control Group. CONCLUSIONS: Elderly age, hypertension, and breast cancer were significantly associated with endometrial polyps. The presence of PROGINS polymorphism was not significantly associated with endometrial polyps. The incidence of malignant polyps was low and strongly associated with bleeding, large-sized polyp and arterial hypertension.

ABSTRACT

OBJETIVO: avaliar as variáveis clínicas e epidemiológicas de risco para câncer de endométrio em mulheres com pólipos endometriais na pós-menopausa, bem como a presença do polimorfismo do receptor da progesterona (PROGINS). MÉTODOS: estudo caso-controle desenhado com 160 mulheres na pós-menopausa com pólipos endometriais, comparado a Grupo Controle de 400 mulheres na pós-menopausa. A genotipagem do polimorfismo PROGINS foi determinada pala reação em cadeia da polimerase (PCR). Aspectos clínicos e epidemiológicos foram comparados entre as mulheres com pólipos endometriais benignos e 118 dos controles normais. Estas variáveis foram também comparadas entre mulheres com pólipos benignos e pólipos malignos. RESULTADOS: a comparação entre o grupo de pólipos benignos e o Grupo Controle mostrou diferença significativa (p<0,05) para as varáveis: idade, raça não-branca, anos da menopausa, paridade, hipertensão arterial, uso de tamoxifeno e antecedente de câncer de mama, todas mais prevalentes no grupo de pólipos endometriais. Após o ajuste para a idade, permaneceram com diferença significativa a paridade (OR=1,1), hipertensão arterial (OR=2,2) e o antecedente de câncer de mama (OR=14,4). Houve seis casos de pólipos malignos (3,7 por cento). A frequência de sangramento para pólipos benignos e malignos foi de 23,4 e 100 por cento, respectivamente, sendo o pólipo grande encontrado em 54,5 por cento dos casos benignos e em 100 por cento dos malignos. A frequência de hipertensão arterial foi de 54,5 por cento para pólipos benignos e 83,3 por cento para pólipos malignos. As frequências do polimorfismo PROGINS T1/T1, T1/T2 e T2/T2 foram 79,9 por cento, 19,5 por cento e 0,6 por cento respectivamente para pólipos benignos e 78,8 por cento, 20,8 por cento e 0,5 por cento para o Grupo Controle. CONCLUSÕES: os pólipos endometriais se mostraram mais frequentes em mulheres de idade avançada, hipertensas e com antecedente de câncer de mama. A presença do polimorfismo PROGINS não mostrou associação significativa com pólipos endometriais. A incidência de pólipos malignos foi baixa, estando fortemente associada à presença de sangramento, tamanho grande do pólipo e hipertensão arterial.

ABSTRACT

Introdução: apesar do critério de Light (cL) ser o mais empregado para diferenciar exsudatos de transudatos pleurais, alguns autores têm sugerido outras variáveis com a mesma finalidade. O objetivo deste estudo é calcular o melhor valor discriminatórioe o rendimento do Colesterol (COL) como teste diagnóstico para diferenciação entre transudatos e exsudatos. Metodologia: num estudo transversal histórico, foram estudados os níveis do COL em 283 líquidos pleurais obtidos, de forma consecutiva, de pacientes em investigação para a causa de síndrome do derrame pleural, num Hospital Universitário e num Centro de Investigações Pneumológicas. Resultados: estudando 250 exsudatos e 33 transudatos, calculamos uma sensibilidade de 83% (IC95% 75,8-85,8) e especificidade de 97% (IC95% 84,2-99,5) para o diagnóstico de exsudato, utilizando o valor discriminatório de 50 mg/dL. Com esta prevalência, de 88,3% de exsudato, o valor preditivo positivo foi de 99,5% eo negativo, de 42,67%. A razão de verossimilhança positiva foi de 27,33 e a negativa, de 0,18. Conclusão: a sensibilidade foi algo inferior ao cL, enquanto a especificidade foi superior. Os resultados obtidos são semelhantes aos observados por outros autores e apresentam o colesterol como parâmetro valioso, rápido e econômico, isolado ou associado a outros marcadores.

ABSTRACT

The intergenerational transmission of violence and the tendency for abused and neglected children to become abusers, delinquents, and violent offenders in their adult life is an important field to be understood. It is also important to understand these backgrounds to guide future preventative interventions. Through a cross-sectional study, the occurrence of abuse during childhood and adolescence of adult women incarcerated in a female state prison at Recife in northeast Brazil was investigated. Among 219 prisoners, 190 accepted to join the research; 149 were young women (23-27 years) with severe educational deficiency. Living in poor socioeconomical conditions with problematic and violent familiar relations, 116 (61 per cent) left home at the end of their adolescence and the same number reported having been abused (p < 0.000015). There was a statistical significance between the abuses suffered and witnessed by the subjects and the perpetration of abuse against children and adolescents by themselves (p < 0.0022 and p < 0.0000049). Parents were the most frequent perpetrators (37.4 per cent). Sexual activity and use of legal and illegal drugs occurred early in adolescence. The group also had a family history of violence. Based on the analysed data of this studied group, the authors assumed that the abuse suffered in childhood and adolescence of these women drove them to be abusers in adult life and could have been a predictive marker for their conduct disorders and subsequent criminal behavior.

ABSTRACT

A dosagem da glicose e amilase vem sendo realizada na rotina de investigação da causa de derrames pleurais. Nosso objetivo é verificar a contribuição destas para o diagnóstico final. Método: estudamos 192 toracocenteses subseqüentes com derrame pleural, entre agosto 1995 e dezembro de 2000. Foram excluídos aqueles nos quais um diagnóstico de certeza não foi possível e pacientes já incluídos anteriormente. As propriedades do teste diagnóstico foram calculadas após identificar o valor discriminatório de maior acurácia pela curva ROC. Resultados: houve predomínio do sexo masculino e a média de idade foi de 50 anos (DP de 19,8). O rendimento de ambas as dosagens para o diagnóstico diferencial entre transudato e exsudato foi ruim. A glicose, com valor discriminatório de < 90mg/dL, mostrou uma sensibilidadede 94% e especificidade de 65% para o diagnóstico da tuberculose. A amilase (valor < 52U/L), para o diagnóstico diferencial entre neoplasia e um grupo composto por tuberculose, parapneumônico e transudato mostrou uma sensibilidade de 56% e especificidade de 58%. Conclusões:a dosagem da glicose e da amilase no líquido pleural não são úteis, isoladamente, para se estabelecer a causa do derrame pleural em nosso meio e não devem ser solicitadas de rotina no início da investigação. Contudo, em casos especiais podem ser de grande ajuda.

ABSTRACT

Tuberculosis is a very common disease usualy related to bad social-economic conditions and sometimes with associated pleural effusion. Pleural sequelae are referred by some authors as a consequence that may interfere with lung function provoking respiratory failure in some critical situations. Some experts try to find clinical and biochemical parameters in order to detect possibilities that could predict future pleural thickening and necessity of closer vigilance to avoid lung function disability. This study is based on the post-treatment roentgenological pleural findings and their correlation with the initial pleural fluid biochemical data, the volume of the effusions and time of patients complains.

ABSTRACT

The childhood is one of the most propitious period of the life to the occurrence of infection by yeasts of the genus Candida. In children with Down's syndrome, besides the predispose factors to bucal candidiasis; macroglossia, bucal muscular incompetence, frequent respiratory diseases, motor difficulty and immunologic deficit are mentioned as additional elements for this fungus disease. It was verified that the children attacked by this syndrome have much more strains of Candida than other children. The aim of this study was to detect the prevalence of phospholipase producer, Candida on the saliva of children with Down's syndrome. Candida albicans was the only identified specie of Candida. The phospholipase production was found in isolated strains from both of study and control. However, the isolated strains of the group of children with Down's syndrome have strongly present phospholipidolitic.

ABSTRACT

As coleçöes entomológicas são tidas como fonte de estudo para compreensão dos mecanismos de doenças humanas, onde os insetos atuam como veículos disseminadores. A manutenção dessas coleçöes é uma preocupação constante da parasitologia uma vez que o acontecimento de fungos por estes insetos é frequente e o desenvolvimento de técnicas mais eficientes se faz necessário pelo conhecimento dos gêneros fúngicos envolvidos. Foram analisadas 12 caixas de coleçöes entomológicas do Setor de Parasitologia do Instituto de Parasitologia do Instituto de Patologia Tropical e Saúde Pública da Universidade Federal de Goiás (SP/IPTSP/UFG). Cada caixa com 1.200 cm 2 possuía em média 200 triatomíneos, 400 mosquitos e 300 moscas. Sessenta insetos foram escolhidos de mameira aleatória destas caixas entomológicas com presumível acometimento de mofos, bolores e/ou leveduras. Dos 60 insetos analisados, verificou-se a ocorrência de fungos em 28 (46,7 por cento) insetos..

ABSTRACT

CONTEXT: Magnesium support to small bowel resection patients. OBJECTIVE: Incidence and treatment of hypomagnesemia in patients with extensive small bowel resection. DESIGN: Retrospective study. SETTING: Metabolic Unit of the University Hospital Medical School of Ribeirão Preto, University of São Paulo, Brazil. PATIENTS: Fifteen patients with extensive small bowel resection who developed short bowel syndrome. MAIN MEASUREMENTS: Serum magnesium control of patients with bowel resection. Replacement of magnesium when low values were found. RESULTS: Initial serum magnesium values were obtained 21 to 180 days after surgery. Hypomagnesemia [serum magnesium below 1.5 mEq/l (SD 0.43)] was detected in 40 percent of the patients [1,19 mEq/l (SD 0.22)]. During the follow-up period, 66 percent of the patients presented at least two values below reference (1.50 mEq/l). 40 percent increased their serum values after magnesium therapy. CONCLUSION: Metabolic control of serum magnesium should be followed up after extensive small bowel resection. Hypomagnesemia may be found and should be controlled

ABSTRACT

The nutritional condition of elderly persons has close relations with their immunologic status and general health. There is no agreement regarding the recommended dietary allowances of energy and of the various nutrients inthe elderly population. Also, studies on this field were carried out in developed Countries, with possibly different cultural, social, and even climatic conditions if compared with Brazil. This paper revises some aspects of the energy and protein metabolism in elderly persons and highlights the necessity for new research lines about the nutritional status and the adequacy of the caloric and protein intake of our aged population in order to enable the development of rational nutritional interventions


El estado nutricional de lo adultos mayores influye en su sistema inmunológico y la salud. No existe un consenso acerca de las necesidades calóricas y de nutrientes para esta población. La mayor parte de los estudios de estas variables fueron realizados en países desarrollados, con condiciones culturales, sociales y hasta climáticas, bastante diferentes del Brasil. Se revisaron algunos aspectos del metabolismo enegético y proteico de los adultos mayores, señalando los estudios necesários para uma evaluación del estado nutricional, que permitan el ajuste correcto de estos parámetros en la dieta de los adultos mayores, elementos indispensables para la planificación de intervenciones nutricionales racionales


O estado nutricional dos idosos é relacionado com o seu estado imunológico e saúde geral. Não existe consenso sobre as necessidades calóricas e dos diversos nutrientes na população idosa. Também, a maioria dos estudos acerca destas variáveis foram realizados em países desenvolvidos, com cultura, condições sociais e mesmo climáticas diferentes daquelas do Brasil. O presente artigo revisa alguns aspectos do metabolismo energético e protéico em idosos, destacando a necessidade da realização de pesquisas para a avaliação do estado nutricional e da adequação calórica e protéica da dieta habitual da nossa população idosa, essenciais para o planejamento de intervenções nutricionais racionais

ABSTRACT

Neste artigo, nós analisamos os maiores estudos sobre suplementaçäo vitamínica na prevençäo de doenças cardiovasculares, seja primária ou secundária. A suplementaçäo vitamínica de vitamina E é recomendada apenas por um dos cinco estudos citados sobre prevençäo primária. Em dois outros estudos ha evidências de que a alta ingestäo de vitamina E é válida para a diminuiçäo da taxa de mortalidade por causas coronarianas em prevençäo primária. Na prevençäo secundária, há somente dois estudos e ambos evidenciaram aumento da mortalidade entre os pacientes recebendo vitamina E.

ABSTRACT

A procura de novos métodos de adesäo tecidual tem sido uma constante nas diversas áreas da cirurgia. Recentemente, atençäo especial tem sido dada a um tipo de adesivo biológico composto por fibrinogênio e trombina, que quando comparado a outros adesivos como o cianoacrilato, apresenta a vantagem de ser totalmente absorvível e é considerado o melhor entre os adesivos teciduais. O presente estudo foi realizado em coelhos e teve como objetivo avaliar, através de exame histopatológico, a reaçäo tecidual produzida pelo adesivo biológico de fibrina na junçäo músculo escleral e compará-la com a reaçäo produzida pela poliglactina 910. A amostra constituída por 24 animais foi separada de acordo com o período
