Estudo epidemiológico e monitoramento de Lamivudina (3TC) e Zidovudina (AZT) na terapêutica do HIV-1 em pacientes de Belém – PA e suas correlações com as funções hepática, renal e nutricional, Belém, Pará

A estimativa de pessoas infectadas pelo HIV no mundo, no ano de 2006, foi cerca de 39,5 milhões. No Brasil, o Ministério da Saúde indica terapia para pacientes com manifestações clínicas associadas ao HIV-1 e para aqueles com contagem de linfócitos T CD4⁺ abaixo de 200 células/ mm³. Paralelamente aos benefícios da terapia anti-retroviral há o reconhecimento de efeitos adversos, como miopatia, lipodistrofia, pancreatite, hepatotoxicidade e acidose lática. A complexidade dos esquemas terapêuticos torna a adesão à terapia difícil, contribuindo para a falha terapêutica. Neste trabalho foi realizado um estudo epidemiológico, de monitoramento de Lamivudina (3TC) e Zidovudina (AZT) e correlacionado com as funções hepática, renal e nutricional em pacientes portadores de HIV-1, atendidos na CASA DIA, em Belém/PA. O grupo populacional estudado constou de 60 portadores do HIV-1 de ambos os gêneros, com faixa etária de 20 a 61 anos, que faziam uso de AZT e/ou 3TC. Os níveis plasmáticos de aminotransferases, uréia e creatinina foram determinados por fotometria de absorção e, por Cromatografia Líquida de Alta Eficiência, foram determinadas as concentrações plasmáticas de 3TC e AZT. O estado nutricional foi avaliado através do Índice de Massa Corpórea (IMC). As concentrações de 3TC variaram de 1,283 a 355,953 μg/mL, enquanto que as de AZT variaram de 0,008 a 22,544 μg/mL. A concentração de 3TC evidenciou associação com a ocupação (p < 0,05) e com a creatininemia (p < 0,0001), mas não com as aminotrasnferases e uremia (p > 0,05). Não encontramos associação entre a concentração de AZT com as informações demográficas e com a creatininemia (p > 0,05), todavia verificou-se associação com as aminotransferases e uremia (p < 0,0001). O IMC revelou associação com todos os parâmetros estudados: concentrações de 3TC, AZT, aminotransferases, uremia e creatininemia (p < 0,05). Concluímos que as concentrações de 3TC podem afetar os níveis de creatinina e sofrem influência do estado nutricional do paciente, enquanto que as concentrações de AZT podem alterar os níveis de aminotransferases, uréia e também são influenciadas pelo estado nutricional, ratificando os processos farmacocinéticos desses fármacos.

Preschool children and excess weight: the impact of a low complexity intervention in public day care centers

Introduction: childhood obesity is a major public health problem, affecting children even at early ages. Objective: to assess the impact of dietary intervention and relatively simple physical activity on the nutritional state of preschoolers. Method: this was an intervention study in public daycare centers targeting children from 2 to 4 years of age, in the State of São Paulo. The sample consisted of 9 daycare centers covering 578 children, with 264 children in the intervention group (IG) and 314 in the comparison group (CG). Intervention was focused on modifications in diet and physical activity, avoiding overloading the routine of daycare centers, for duration of one year. A zBMI score > 1 (zBMI) and < 2 was considered risk of being overweight, and > 2 zBMI was considered excess weight (overweight and obese). Analysis was done by frequency calculations, comparisons of proportions by χ2, mean comparisons by t-student and calculations according to Pearson’s correlation coefficient. Results: IG showed an inverse correlation between the initial zBMI of the children and the difference with the zBMI at the end of the intervention (rP = -0.39, p <0.0001). The mean difference of zBMI of the overweight children in IG between the beginning and the end of the study period was negative (-0.46 z score), indicating weight reduction, while the children in the CG was positive (+0. 17 z score) (p = 0.0037). Conclusion: intervention in diet and physical activity in overweight preschool children in daycare centers could have a favorable impact on the evolution of their nutritional state.

Classificação do grau de comprometimento motor e do índice de massa corpórea em crianças com paralisia cerebral

Children with cerebral palsy due to movement and posture disorders might have an injured nutritional state. This study's objective was to classify the body mass index of children with cerebral palsy and verify its relation with the injury level of gross motor function. Twenty children, male and female sex, with cerebral palsy with ages between 2 and 14 years participated in the study. They were chosen from a rehabilitation center with physiotherapy, occupational and speech therapy accompaniment. Children were classified according to the gross motor function classification scale. The anthropometric measures of each child weight, heel-knee length, estimated stature and body mass index were gauged. The body mass index was classified according to the Center for Disease Control and Prevention's body mass index percentile calculator for children and teenagers. The obtained data didn't show any relation between the gross motor function and body mass index. The reduced number of participants and the fact of all children be accompanied in dysphagia clinics and, when necessary, nutrition clinics, might have influenced these results.

Indicadores Antropométricos do Estado Nutricional de Idosas Praticantes e Não Praticantes de Exercício Fisíco na Zona Norte de São José do Rio Preto-SP

Although the regular practice of physical exercise for the maintenance of the nutritional state and quality of life is important, it is not a common habit among the elderly, especially those of the lower income social bracket. The objective was to characterize and compare according to social-economic conditions and anthropometric indexes of the nutritional state of the elderly who regularly practice and those who do not practice exercises, offered at no cost, in the Northern zone of São José do Rio Preto-SP. In this study, 110 elderly women participated, of which 60 (group P) exercised regularly and 50 did not (group NP). Group P participated in a special gym program, free of charge, for at least 2 years, 2 to 3 times a week, one hour a day. Group NP was recruited from the same location as Group P. The comparison between the groups of elderly women was proportionately distributed according to marital status, level of education, means of locomotion, results of body mass index (IMC), waist to hip ratio (RCQ) and calf circumference, using the chi-square test. Comparisons were also made of average age, per capita family income, individual income, IMC, arm and triceps skin fold measured by t-Test. Differences were not found in all the comparisons made. The variables that stood out were the IMC (overweight) and RCQ (risk of chronic diseases) results, which were above what was expected, and the high frequency of walking and riding buses for both groups of elderly women (about 60%). We came to the conclusion that the low-intensity exercise program evaluated made no difference in the nutritional profile of the elderly who also used walking as a means of getting around.

Malaspina 2010: observaciones de R/ETS

[EN]Respiratory electron transport system (ETS) activities have been used, in the past, to study respiration in many marine organisms and many different environments. The methodology follows standard practices of enzymology, by attempting to measure the maximum velocity of the enzyme reaction (Vmax) sensu Michaelis-Menten. Under controlled conditions of nutritional state the ETS method is well correlated with in situ respiration. In the interdisciplinary Expedition MALASPINA 2010, that circumnavigated the planet, we had the chance in three of seven transects (Cape Town to Perth; Perth to Sydney and Cartagena de Indias to Cartagena) to take zooplankton samples from the southern Indian Ocean and from North Atlantic Ocean. From these samples we measured protein and 150 ratios between in vivo respiration and potential respiration (ETS activity) in three size-classes of zooplankton between 100?m to > 1000?m, in the upper 150 meters of the water column. Normally, the measurements were made on fresh naturally nourished zooplankton (in situ). When biomass permitted, measurements were also made on zooplankton starved for 24 h. With this data we are investigating the variations in the R/ETS ratio and Kleiber?s law under different nutritional conditions, different oceanographic conditions, and different oceanographic regions. This analysis will help our ongoing investigation of ETS activity as an index of both respiration and of living biomass. The information acquired will facilitate the calculation of zooplankton respiration for some relatively unexplored areas of the Indian and Atlantic oceans. This data will then be available for integration with results of other Malaspina research programs

Lipid profiles and outcome in patients treated by intravenous thrombolysis for cerebral ischemia

OBJECTIVE:To determine whether low low-density lipoprotein cholesterol (LDL-C) but not high-density lipoprotein cholesterol (HDL-C) and triglyceride concentrations are associated with worse outcome in a large cohort of ischemic stroke patients treated with IV thrombolysis. METHODS:Observational multicenter post hoc analysis of prospectively collected data in stroke thrombolysis registries. Because of collinearity between total cholesterol (TC) and LDL-C, we used 2 different models with TC (model 1) and with LDL-C (model 2). RESULTS:Of the 2,485 consecutive patients, 1,847 (74%) had detailed lipid profiles available. Independent predictors of 3-month mortality were lower serum HDL-C (adjusted odds ratio [(adj)OR] 0.531, 95% confidence interval [CI] 0.321-0.877 in model 1; (adj)OR 0.570, 95% CI 0.348-0.933 in model 2), lower serum triglyceride levels ((adj)OR 0.549, 95% CI 0.341-0.883 in model 1; (adj)OR 0.560, 95% CI 0.353-0.888 in model 2), symptomatic ICH, and increasing NIH Stroke Scale score, age, C-reactive protein, and serum creatinine. TC, LDL-C, HDL-C, and triglycerides were not independently associated with symptomatic ICH. Increased HDL-C was associated with an excellent outcome (modified Rankin Scale score 0-1) in model 1 ((adj)OR 1.390, 95% CI 1.040-1.860). CONCLUSION:Lower HDL-C and triglycerides were independently associated with mortality. These findings were not due to an association of lipid concentrations with symptomatic ICH and may reflect differences in baseline comorbidities, nutritional state, or a protective effect of triglycerides and HDL-C on mortality following acute ischemic stroke.
