Abstract: Introducción: El aumento del metabolismo basal, hiperfagia asociada con pérdida de peso son algunas de las principales manifestaciones clínicas que ocurren en el hipertiroidismo. Sin embargo, hay pocos estudios disponibles acerca de la necessidad y del gasto energético del paciente. Caso clínico: Varón de 24 a os de edad con 61,5 kg de peso y estatura de 1,78 m, con el diagnóstico de hipertiroidismo por enfermedad de Graves (T3 libre = 17,6 pg/ml; T4 livre >6,0 ng/dl; TSH <0,004 IU/ml) y con los siguientes síntomas: pérdida de peso, aumento de apetito y hiperactividad. La calorimetría indirecta se realizó para estimar el consumo energético real para definir la conduta nutricional durante la hospitalización. El gasto energético basal fue de 2574 kcal. Conclusión: El presente estudio sugiere que la medición del gasto energético por calorimetría indirecta es una herramienta importante para la evaluación de las necesidades de energía y la adecuación de la dieta de un paciente con tirotoxicosis por enfermedad de Graves. Se necesitan más estudios para determinar el impacto de esta conducta en la evaluación de la respuesta al tratamiento del hipertiroidismo. IIntroduction: An increased basal metabolism rate and hyperphagia associated with weight loss are among the main clinical manifestations of hyperthyroidism. However, few literature reports are available regarding the adequacy of calorie consumption based on the energy expenditure of the patient. Case Report: A 24-year-old male patient (weight 61.5 kg, height 1.78 m) with a diagnosis of hyperthyroidism due to Graves' disease and initial hormone values consistent with this disease (free T3=17,6 pg/ml; free T4>6,0 ng/dl; TSH<0,004 IU/ml). Indirect calorimetry was performed in order to estimate real energy expenditure and adequacy of the nutritional conducts adopted during hospitalization. The patient had a resting energy expenditure of2574 kcal. Conclusion: The present study suggests that the measurement of energy expenditure by indirect calorimetry is an important tool for the evaluation of the energy requirements and diet adequacy of a patient with thyrotoxicosis due to Graves' disease.

Abstract: Introduction: HIV-seropositive patients have shown changes in body composition such as lipoatrophy in certain regions of the body and lipohypertrophy in others, representing characteristics of lipodystrophy syndrome. It is important to monitor the quantity of fat per body segment using practical and low-cost methods in order to optimize the treatment of this group. Objectives: To correlate the body composition per body segment obtained by anthropometric measurements and by segmental bioelectrical impedance with DXA in HIV-seropositive patients on antiretroviral treatment Methods: We measured circumferences (arm, waist, hip, thigh and calf) and skinfolds (biceps, triceps, subscapular, suprailiac) and performed segmental bioelectrical impedance (BIA) analysis and DXA. The Pearson test was used to determine correlations and the St. Laurent test was used to assess concordance between variables. Results: We evaluated 26 patients, 35% of whom were overweight. The triceps skinfold (TSF), waist circumference (WC) and thigh circumference (TC) were significantly correlated with the measurement obtained by the gold standard (p<0.01). There was no concordance between the values obtained by segmental BIA and by DXA. Conclusions: Anthropometric measurements such as TSF, WC and TC are importantfor the monitoring of changes in body composition among HIV-seropositive patients on antiretroviral treatment. Segmental BIA did not prove to be appropriate for the assessment of body composition in HIV-seropositive patients. Introducción: Se ha descrito cambios en la composición corporal de pacientes infectados por VIH, tales como la lipoatrofia en ciertas regiones del cuerpo y lipohipertrofia en otros, en representación de las características del síndrome de lipodistrofia. Es importante controlar la cantidad de grasa corporal por segmento utilizando métodos prácticos y de bajo costo con el fin de optimizar el tratamiento de este grupo. Objetivos: correlacionar la composición corporal por segmento corporal obtenidos por las mediciones antropométricas y por impedancia bioeléctrica com DXA segmentaria en pacientes seropositivos al VIH en tratamiento antir-retroviral. Métodos: Se midieron las circunferencias de brazo, cintura, cadera, muslo y pantorrilla y los pliegues cutáneos: bíceps, tríceps, subescapular, suprailíaco) y se realizaron impedancia bioeléctrica segmentaria (BIA) el análisis y DXA. La prueba de Pearson se utilizó para determinar las correlaciones y la prueba de San Lorenzo se utilizó para evaluar la concordancia entre las variables. Resultados: Se evaluaron 26 paci

Abstract: purpose: to compare the serum levels of five markers of oxidative stress and assisted reproduction (ar) outcomes among infertile patients, with tubal and/or male factor and with polycystic ovary syndrome (pcos). methods: 70 patients were included, 58 with tubal and/or male factor infertility and 12 with pcos, who underwent controlled ovarian stimulation to perform intracytoplasmic sperm injection (icsi). a blood sample was collected between the third and fifth day of the menstrual cycle in the month prior to ovarian stimulation. we analyzed the levels of malondialdehyde, hydroperoxides, protein oxidation products, glutathione and vitamin e, by reading the absorbance with a spectrophotometer and by high performance liquid chromatography (hplc). data were analyzed statistically by the student's t-test and fisher's exact test. results: significant increases in the body mass index, ovarian volume and number of antral follicles were observed in pcos patients, as well as the use of a lower total dose of follicle stimulating hormone for these patients. there were no differences in the response to ovarian stimulation, in the results of ar or serum levels of malondialdehyde, hydroperoxides, advanced oxidation protein products, glutathione and vitamin e between groups. conclusions: the present data did not demonstrate a difference in the levels of serum markers of oxidative stress or in ar results when comparing non-obese infertile patients with pcos and controls. these data suggest that the results of ar may not be compromised in this specific subgroup of patients with pcos. however, interpretations of the action of oxidative stress on the results of ar are still not clear and the reproductive implications of oxidative stress need to be better evaluated.

Abstract: purpose: to compare serum markers of oxidative stress between infertile patients with and without endometriosis and to assess the association of these markers with disease staging. methods: this was a prospective study conducted on 112 consecutive infertile, non-obese patients younger than 39 years, divided into two groups: endometriosis (n=48, 26 with minimal and mild endometriosis - stage i/ii, and 22 with moderate and severe endometriosis - stage iii/iv) and control (n=64, with tubal and/or male factor infertility). blood samples were collected during the early follicular phase of the menstrual cycle for the analysis of serum malondialdehyde, glutathione and total hydroxyperoxide levels by spectrophotometry and of vitamin e by high performance liquid chromatography. the results were compared between the endometriosis and control groups, stage i/ii endometriosis and control, stage iii/iv endometriosis and control, and between the two endometriosis subgroups. the level of significance was set at 5% (p<0.05) in all analyses. results: vitamin e and glutathione levels were lower in the serum of infertile women with moderate/severe endometriosis (21.7±6.0 mmol/l and 159.6±77.2 nmol/g protein, respectively) compared to women with minimal and mild endometriosis (28.3±14.4 mmol/l and 199.6±56.1 nmol/g protein, respectively). total hydroxyperoxide levels were significantly higher in the endometriosis group (8.9±1.8 μmol/g protein) than in the control group (8.0±2 μmol/g protein) and among patients with stage iii/iv disease (9.7±2.3 μmol/g protein) compared to patients with stage i/ii disease (8.2±1.0 μmol/g protein). no significant differences in serum malondialdehyde levels were observed between groups. conclusions: we demonstrated a positive association between infertility related to endometriosis, advanced disease stage and increased serum hydroxyperoxide levels, suggesting an increased production of reactive species in women with endometriosis. these data, taken togeth
The political parallelism in question
ALBUQUERQUE, Afonso de
Revista Compolítica , 2012,
Abstract: The text aims to analyze the contribution and limits to the use of the concept of ""political parallelism"" for comparative studies in political communication. To the present, the concept has been used in a binary opposition to the ""independent"" or ""objective"" model of journalism, so that every situation that does not fit the later would be covered by the former. Alternatively, it suggests that this type of opposition makes sense only in the context of Western societies, and that both categories only apply in contexts in which political systems can coexist with a competitive environment of reasonable institutional stability.
Propaganda política e a constru o da imagem partidária no Brasil
Albuquerque, Afonso de
Civitas , 2002,
Abstract: Tradicionalmente o partido político tem sido considerado um elemento frágil na explica o do voto no Brasil. Nesse sentido, tanto a escolha eleitoral apresenta tra os acen-tuadamente personalistas, como as campanhas eleitorais da maioria dos partidos políticos, centream-se fundamentalmente na imagem do candidato. EWm contrapartida, as regras estabelecidas pela legisla o brasileira para a propaganda política gratuita na televis o concedem tempo aos partidos e n o aos candidatos. As regras do jogo imputam aos dirigentes partidários o poder de determinar quais candidatos ter o acesso à televis o e em que condi es: a distribui o do tempo entre os candidatos, a atribui o de tratamento especial a algum deles, entre outras. O assunto n o se esgota no tratamento dispensado aos candidatos individualmente, mas contempla a possibilidade de os partidos estabelecerem estratégias gerais de ocupa o do espa o mediático. Pretendemos, com este artigo, constituir as bases para a investiga o do processo de constru o de imagem dos grandes partidos envolvidos na campanha eleitoral de 2002.

Comunica??o, Mídia e Consumo , 2008,
Abstract: Resumo O texto analisa as três primeiras edi es do Manual da Reda o editado pelo jornal Folha de S.Paulo: 1984, 1987 e 1992. Mais do que fundamental na estrutura o do novo jornalismo brasileiro pós-ditadura, as edi es constituem um manifesto no qual o jornal reivindica ocupar um papel de destaque na nova democracia em forma o. A análise se prende, em especial, ao modo como os manuais buscam legitimar esse papel baseado em um tipo particular de contrato representativo; um vínculo comercial, antes que eleitoral. Palavras-chave: Jornalismo; democracia; contrato representativo; Manual da Reda o da Folha de S.Paulo. Resumen El texto se propone analizar las tres primeras ediciones del Manual da Reda o editado por el diario Folha de S.Paulo: 1984, 1987 y 1992. Además de desempe ar un papel fundamental en la estructuración del nuevo periodismo brasile o posterior a la dictadura, las ediciones constituyen un manifiesto en el cual el diario pretende desempe ar un papel destacado en la nueva democracia que estaba en formación. El objetivo de este análisis es determinar la manera en que los manuales buscan legitimar ese papel basado en un tipo especial de contrato representativo en el cual el vinculo comercial es más importante que el vinculo electoral. Palabras-clave: Periodismo; democracia; contrato representativo; Manual da Reda o del diario Folha de S.Paulo. Abstract The main purpose of this paper is to analyze the first three editions of the Writing Manuals (Manual da Reda o – 1984, 1987 and 1992), edited by th daily newspaper Folha de S.Paulo. These manuals were fundamental for the structuring of the new Brazilian journalism during the post-dictatorship period. Furthermore, they are a manifest where the newspaper claims for an important place in the new Brazilian democracy in formation. The aim of this analysis is to ascertain how these manuals try to legitimate this position. They have a sort of special representative contract where commercial bonding is more important than the electoral one. Keywords: Journalism; democracy; representative contract; Folha de S.Paulo Writing Manual.
