ABSTRACT Introduction: the working performance of certain jobs determines a high level of physical load from the part of the workers, for what the necessity is imposed of having an appropriate food diet to preserve the physical and mental health. Objective: to design a food diet for welders and smiths starting from the energy expense in working activities. Materials and methods: a field study was carried out starting from a probabilistic sample of welders and smiths from the Industrial Railroad Enterprise Jose Valdes Reyes. A procedure was performed allowing to determine the energy expenditure of the activities they develop. Several techniques like direct observation, interviews, brain storm, direct measure of physiological variable and equations were used to calculate the energy expenditure. Results: three diet variants were designed adjusted to the energy expenditure of the three working places of the before mentioned enterprise. Conclusions: it is expected the application of the designed diets will contribute to keeping good health of the workers in those working places (AU).

Oral and enteral nutrition therapy in inflammatory bowel diseases among the pediatric population: a literature review / Terapia nutricional oral e enteral nas doenças inflamatórias intestinais em crianças e adolescentes: uma revisão de literatura

ABSTRACT Objectives: To review the literature on oral and enteral nutrition therapy and investigate the evidence of its efficacy as a treatment, as well as in preventing relapses and reducing symptoms of inflammatory bowel diseases in the pediatric population. Data source: We performed a bibliographic search in the PubMed, Web of Science, and Latin American and Caribbean Health Sciences Literature (Literatura Latino-Americana e do Caribe em Ciências da Saúde - Lilacs) databases, using the keywords "inflammatory bowel disease," "diet," and "diet therapy" in English and Portuguese, with filters for pediatric studies published in the previous five years. Data summary: We selected 16 articles for this study, nine on exclusive and/or partial enteral nutrition and seven on modified oral diets, such as the specific carbohydrate diet (SCD) and the Crohn's Disease exclusion diet (CDED). The studies found evaluated the anthropometric profile of patients and the inflammatory profile of diseases in children before and after the introduction of each specific nutrition therapy. All interventions presented positive changes in these parameters; however, the results were inconclusive regarding the efficacy of SCD and CDED in the treatment and prevention of relapses. Conclusions: Exclusive enteral nutrition has proven to be effective in inducing remission of Crohn's Disease, and the use of partial enteral nutrition for maintenance treatment has shown promising results. Other modified oral diets are inconclusive concerning their effectiveness, requiring further randomized controlled clinical trials.

RESUMO Objetivos: Revisar a literatura quanto à terapia nutricional oral e enteral e verificar evidências de sua eficácia tanto para tratamento quanto para prevenção de recidivas e redução de sintomas das doenças inflamatórias intestinais em pediatria. Fonte de dados: Foi realizada pesquisa bibliográfica nas bases de dados PubMed, Web of Science e Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs) utilizando os seguintes descritores em inglês: inflammatory bowel disease, diet e diet therapy; e os seguintes descritores em português: doenças inflamatórias intestinais e dietoterapia, com os filtros de estudo em Pediatria e no máximo cinco anos de publicação. Síntese dos dados: Foram selecionados 16 artigos para este estudo, sendo nove sobre o uso de nutrição enteral exclusiva e/ou parcial e sete sobre modificações da dieta oral, como a dieta específica de carboidratos (SCD) e a dieta de exclusão na Doença de Crohn (CDED). Os estudos encontrados avaliaram o perfil antropométrico dos pacientes e o perfil inflamatório das doenças em crianças antes e depois da introdução de cada terapia nutricional específica. Em todas as intervenções, foram observadas mudanças positivas nesses parâmetros, entretanto os resultados mostraram-se inconclusivos em relação à eficácia da SCD e da CDED no tratamento e na prevenção de recidivas. Conclusões: A nutrição enteral exclusiva mostrou-se uma terapia eficaz para a indução da remissão na Doença de Crohn, e o uso da nutrição enteral parcial para tratamento de manutenção vem exibindo resultados promissores. As demais modificações de dietas orais são inconclusivas a respeito de sua eficácia, sendo necessários mais ensaios clínicos randomizados e controlados.

Prevention of rocuronium induced mast cell activation with prophylactic oleuropein rich diet in anesthetized rabbits

Abstract Purpose: The effect of a prophylactic oleuropein-rich diet before anesthesia accompanied by the widely-used steroid-based neuromuscular drug rocuronium on mast cell activation was investigated in the study. Methods: 14 rabbits used in the study. The rabbits in the oleuropein group were given oleuropein-rich extract added to the animals' water at doses of 20 mg/kg oleuropein for 15 days orally. After 15 days, all rabbits in the two groups were given general anesthesia with rocuronium of 1 mg/kg. After 1 day, animals were sacrificed and the liver tissue sections stained with H&E, toluidine blue and tryptase for immunohistochemical study. Results: There was no statistically significant difference between ALT, AST and albumin averages of the oleuropein and control groups (p> 0.05). The tryptase average of the control group was higher than the tryptase average of the oleuropein group and this difference was statistically significant (p=0.003). The T. blue average in the oleuropein group was higher than the control group. However, there was no statistically significant difference between groups (p=0.482). Conclusions: Rocuronium adverse effects, like hypersensitivity and anaphylaxis, may limit routine use of this substance. The use of oleuropein reduced the number of inflammatory cells and prevented degranulation.

Tryptophan overloading activates brain regions involved with cognition, mood and anxiety

ABSTRACT Tryptophan is the only precursor of serotonin and mediates serotonergic activity in the brain. Previous studies have shown that the administration of tryptophan or tryptophan depletion significantly alters cognition, mood and anxiety. Nevertheless, the neurobiological alterations that follow these changes have not yet been fully investigated. The aim of this study was to verify the effects of a tryptophan-enriched diet on immunoreactivity to Fos-protein in the rat brain. Sixteen male Wistar rats were distributed into two groups that either received standard chow diet or a tryptophan-enriched diet for a period of thirty days. On the morning of the 31st day, animals were euthanized and subsequently analyzed for Fos-immunoreactivity (Fos-ir) in the dorsal and median raphe nuclei and in regions that receive serotonin innervation from these two brain areas. Treatment with a tryptophan-enriched diet increased Fos-ir in the prefrontal cortex, nucleus accumbens, paraventricular hypothalamus, arcuate and ventromedial hypothalamus, dorsolateral and dorsomedial periaqueductal grey and dorsal and median raphe nucleus. These observations suggest that the physiological and behavioral alterations that follow the administration of tryptophan are associated with the activation of brain regions that regulate cognition and mood/anxiety-related responses.

Lifestyle Intervention on Metabolic Syndrome and its Impact on Quality of Life: A Randomized Controlled Trial / Intervenção de Estilo de Vida na Síndrome Metabólica e seu Impacto na Qualidade de Vida: Um Estudo Controlado Randomizado

Abstract Background: Lifestyle intervention programs can reduce the prevalence of metabolic syndrome (MetS) and, therefore, reduce the risk for cardiac disease, one of the main public health problems nowadays. Objective: The aim of this study was to compare the effects of three types of approach for lifestyle change programs in the reduction of metabolic parameters, and to identify its impact on the quality of life (QOL) of individuals with MetS. Methods: A randomized controlled trial included 72 individuals with MetS aged 30-59 years. Individuals were randomized into three groups of multidisciplinary intervention [Standard Intervention (SI) - control group; Group Intervention (GI); and Individual Intervention (II)] during 12 weeks. The primary outcome was change in the metabolic parameters, and secondarily, the improvement in QOL measures at three moments: baseline, 3 and 9 months. Results: Group and individual interventions resulted in a significant reduction in body mass index, waist circumference, systolic blood pressure at 3 months and the improvement of QOL, although it was significantly associated with the physical functioning domain. However, these changes did not remain 6 months after the end of intervention. Depression and anxiety were significantly associated with worse QOL, although they showed no effect on the response to intervention. Conclusion: Multidisciplinary intervention, especially in a group, might be an effective and economically feasible strategy in the control of metabolic parameters of MetS and improvement of QOL compared to SI, even in a dose-effect relationship.

Resumo Fundamento: Programas de intervenção em estilo de vida podem reduzir a prevalência de síndrome metabólica (SM) e, portanto, diminuir o risco de doença cardíaca, um dos principais problemas de saúde pública da atualidade. Objetivo: Comparar os efeitos de três tipos de abordagem para programas de mudança no estilo de vida visando à redução dos parâmetros metabólicos, assim como identificar seu impacto na qualidade de vida (QV) de indivíduos com SM. Métodos: Estudo randomizado controlado incluindo 72 indivíduos com SM com idade de 30 a 59 anos, que foram randomizados em três grupos de intervenção multidisciplinar [Intervenção Padrão (IP) - grupo controle; Intervenção em Grupo (IG); e Intervenção Individual (II)] por 12 semanas. O desfecho primário foi a mudança nos parâmetros metabólicos, e o secundário, a melhora nas medidas de QV em três momentos: condição basal, aos 3 e aos 9 meses. Resultados: As intervenções IG e II resultaram em uma significativa redução em índice de massa corporal, circunferência abdominal e pressão arterial sistólica, e em melhoras da QV aos 3 meses, embora significativamente associadas com o domínio 'capacidade funcional'. Tais mudanças, entretanto, não permaneceram 6 meses após o final da intervenção. Depressão e ansiedade associaram-se significativamente com pior QV, embora sem efeito na resposta à intervenção. Conclusão: A intervenção multidisciplinar, em especial em grupo, pode ser uma estratégia efetiva e economicamente possível para controlar os parâmetros metabólicos de SM e melhorar a QV quando comparada à IP, mesmo em uma relação de dose-efeito.

Origen, componentes y posibles mecanismos de acción de la dieta mediterránea / Origin, components and mechanisms of action of the Mediterranean diet

The Mediterranean diet is currently considered a healthy dietary pattern. It includes a great variety of foods, which are eaten in moderation and within a positive social environment. The generic term “Mediterranean diet” was born after the “Seven Countries Study” led by Ancel Keys around 1960. This dietary pattern is characterized by a high intake of fruits and vegetables, whole grains, legumes, nuts, fish, white meats and olive oil. It also includes moderate consumption of fermented dairy products, low intake of red meat and drinking wine with moderation during meals. Nutritionally, this diet is low in saturated fats and animal protein, high in antioxidants, fiber and monounsaturated fats, and exhibits an adequate omega-6/omega-3 fatty acid balance. The main bioactive compounds, which explain the health benefits of this dietary pattern, are antioxidants, fiber, monounsaturated and omega-3 fatty acids, phytosterols and probiotics. This diet is not exclusively confined to the Mediterranean Basin. Central Chile has a Mediterranean climate and our agriculture and culinary traditions are similar to those found in Mediterranean countries. Therefore, it is fundamental to increase awareness about the richness of our natural produce as well as our culinary culture, which may bring many health benefits and improve the quality of life in our population.

Green banana pasta diet prevents oxidative damage in liver and kidney and improves biochemical parameters in type 1 diabetic rats

ABSTRACT Objective In this study, the effects of a green banana pasta diet on the oxidative damage from type 1 diabetes mellitus (DM) were investigated. Materials and methods Formulations containing 25 (F25), 50 (F50), and 75% (F75) of green banana pasta were prepared and included in a 12-week diet of Wistar rats with alloxan-induced type 1 DM. The effects of these formulations in preventing oxidative damage in kidneys and liver homogenates of rats were evaluated using the TBARS assay (lipid peroxidation in liver) and the DNPH assay (protein oxidation in liver and kidneys). Furthermore, the effects of the formulations on the fasting glycemia, fructosamine levels, renal function (creatinine), liver function (enzymes aspartate aminotransferase [AST] and alanine aminotransferase [ALT]), and lipid profile (total cholesterol and fractions) in the serum of rats were evaluated in addition to the evaluation of the centesimal composition and microbiological analysis of the produced green banana pasta. Results An F75 diet prevented hyperglycemia in diabetic rats (p < 0.05) compared to the diabetic rats fed a standard diet (commercial feed). Notably, the protein oxidation in both the liver and kidneys were prevented in diabetic rats on the F50 or F75 diets compared to the control group, whereas the lipid peroxidation was only prevented in the liver (p < 0.05). Moreover, all formulations prevented an increase in the amount of triglycerides in the serum of the rats. The F25 and F50 diet prevented the increase of cholesterol, and the F75-based diet of ALT and fructosamine (p < 0.05) supported the anti-hyperglycemic effects and the protection against oxidative damage. Conclusion The green banana pasta (F75) diet showed great potential for preventing complications associated with diabetes.

Prevalência de violência física por parceiro íntimo em homens e mulheres de Florianópolis, Santa Catarina, Brasil: estudo de base populacional / Prevalence of intimate partner physical violence in men and women from Florianópolis, Santa Catarina State, Brazil: a population-based study / La prevalencia de la violencia física en parejas íntimas entre hombres y mujeres de Florianópolis, Santa Catarina, Brasil: estudio basado en la población

Investigou-se a associação entre sexo e violência física entre parceiros íntimos. Encontrou-se prevalência de sofrer qualquer violência física (17%), violência física moderada (16,6%) e violência física grave (7,3%). Não houve diferença significativa para violência física moderada em homens e mulheres, porém, quanto mais grave o ato maior a ocorrência deste nas mulheres. Por meio de regressão logística testou-se a associação da violência com o sexo, ajustando-se às variáveis exploratórias. Mulheres de maior idade, viúvas/separadas, pobres, menos escolarizadas e pretas registram maior probabilidade de sofrer violência. Nos homens, a prevalência de violência física grave apresentou alteração significativa apenas para estado civil. Uso abusivo de álcool por mulheres representou maior chance de sofrer violência física.

This study investigated the association between gender and intimate partner physical violence. A random cluster sample was chosen as the baseline cohort population in a cross-sectional design. Lifetime prevalence rates were as follows: any physical violence (17%), moderate physical violence (16.6%), and severe physical violence (7.3%). There were no significant differences between genders in moderate physical violence, but women were more likely to suffer severe abuse. Logistic regression was used to identify associations between violence and gender, adjusting for exploratory variables. Women that were older, widowed/separated, had less schooling or lower income, and African-descendants were all more likely to have suffered intimate partner violence. Prevalence of severe physical violence experienced by men only changed significantly according to marital status. Alcohol abuse by women increased the odds of suffering physical violence.

Se investigó la asociación entre el sexo y la violencia física entre parejas íntimas. La prevalencia de sufrir violencia física (17%), la violencia física moderada (16,6%) y la violencia física grave (7,3%). No hubo diferencia significativa en la violencia física moderada en hombres y mujeres, sin embargo, más grave es la mayor ocurrencia de este hecho en las mujeres. Por regresión logística se evaluó la relación entre la violencia y el sexo, y el ajuste de las variables exploratorias. Las mujeres mayores de edad, viudas/separadas, más pobres, menos educadas y negras son más propensas a sufrir violencia. En los hombres, la prevalencia de la violencia física grave cambió significativamente sólo con el estado civil. El abuso de alcohol por mujeres representan un mayor riesgo de sufrir violencia.

changes in their everyday lives, making it an aggravating factor along the dialysis treatment because of poor adherence. The object of this study was to identify the determinants of chronic renal disease patients? adherence to dietary therapy treatment. These patients were receiving treatment at the specialized hemodialysis service of a hospital in the metropolitan area of Goiania, Goias state. Methods: This is across-sectional study of qualitative approach. Data collection for patient identification began with the analysis of medical records, followed by semi-structured interviews with five adult patients and one elderly patient. Thematic content analysis was used to analyze the data. Results: The results were grouped into the following categories: a) dietary therapy in hemodialysis ? all the interviewees reported difficulties in following quantitative and qualitative food restrictions, particularly to liquids; b) length of hemodialysis ? over time, the majority of the interviewees resumed foodconsumption without restrictions; c) psychosocial factors ? the emotional and social responses were representations of threats to health due to the dietary therapy and dialysis treatment. Conclusions: In conclusion, dietary therapy and dialysis treatment imply behavioral changes and involve a variety of prescriptions and recommendations resulting in different levels of adherence. Adherence is a continuous and dynamic process which comprises not only overall behavior, but also a number of individual behaviors.

Objetivo: O tratamento dietoterápico do paciente que realiza hemodiálise exige profundas mudanças no cotidiano, tornando-se um agravante ao longo do tratamento dialítico, em virtude da baixa adesão. O objetivo deste estudo foi identificar os determinantes da adesão ao tratamento dietoterápico dos pacientes com Doença Renal Crônica, atendidos no Serviço Especializado em Hemodiálise de um hospital da região metropolitana de Goiânia, Goiás. Métodos: Estudo transversal de abordagem qualitativa. A coleta de dados de identificação dos pacientes iniciou-se nos prontuários, seguida da fase de entrevistas semiestruturadas com cinco pacientes adultos e um idoso. Os dados foram analisados por meio de análise de conteúdo temática. Resultados: Os resultados foram agrupados em categorias: a) dietoterapia em hemodiálise ? Todos os entrevistados referiram dificuldades de seguir a restriçãoquantitativa e qualitativa da alimentação, principalmente de líquidos; b) tempo de hemodiálise ? Ao longo dos anos, a maioria dos entrevistados voltou a consumir alimentos sem restrições; c) fatores psicossociais ? As respostas emocionais e sociais foram representações de ameaças à saúde em virtude do tratamento dietoterápico e dialítico. Conclusões: Conclui-se que os tratamentos dietoterápico e dialítico implicamalterações comportamentais, e envolvem uma diversidade de prescrições e recomendações, possibilitando níveis diferentes de adesão. A adesão é um processo contínuo e dinâmico que compreende não apenas um comportamento global, mas vários comportamentos individuais.

Intervenções em Dieta e Pressão Arterial na América Latina - Revisão Sistemática e Meta-Análise / Dietary Interventions and Blood Pressure in Latin America - Systematic Review and Meta-Analysis

Fundamento: Pressão arterial elevada é o principal fator de risco para doenças cardiovasculares. Baixos índices de controle da pressão arterial em populações latino-americanas reforçam a necessidade de reunir evidências sobre terapias eficazes. Objetivo: Avaliar o efeito das intervenções de modificações de dietas sobre pressão arterial em populações latino-americanas. Métodos: Revisão sistemática. Foram pesquisadas diversas bases de dados (MEDLINE-PubMed, Embase, Cochrane Library, CINAHL, Web of Science, Scopus, SciELO, LILACS e BVS) e realizada busca manual até abril de 2013. Foram incluídos estudos paralelos de intervenções em dieta em populações adultas da América Latina reportando pressão arterial (em mmHg) antes e após a intervenção. Resultados: Dos 405 estudos encontrados, 10 ensaios clínicos randomizados foram incluídos e divididos em 3 subgrupos, de acordo com a dieta proposta como intervenção. Houve redução não significativa da pressão arterial sistólica nos subgrupos de substituição mineral -4,82 (IC 95%: -11,36 a 1,73 mmHg) e padrões complexos -3,17 (IC 95%: -7,62 a 1,28 mmHg). Para a pressão arterial diastólica, com exceção do subgrupo de dietas hiperproteicas, todos os subgrupos apresentaram redução significativa, com -4,66 (IC 95%: -9,21 a -0,12 mmHg) e -4,55 (IC 95%: -7,04 a -2,06 mmHg) para substituição mineral e padrões complexos, respectivamente. Conclusão: A evidência disponível sobre os efeitos de alterações de dieta na pressão arterial em populações latino-americanas indica um efeito homogêneo, porém não significativo, para pressão arterial sistólica. Estudos maiores e com maior rigor ...

Background: High blood pressure is the major risk factor for cardiovascular disease. Low blood pressure control rates in Latin American populations emphasize the need for gathering evidence on effective therapies. Objective: To evaluate the effects of dietary interventions on blood pressure in Latin American populations. Methods: Systematic review. Electronic databases (MEDLINE/PubMed, Embase, Cochrane Library, CINAHL, Web of Science, Scopus, SciELO, LILACS and VHL) were searched and manual search for studies published up to April 2013 was performed. Parallel studies about dietary interventions in Latin American adult populations assessing arterial blood pressure (mm Hg) before and after intervention were included. Results: Of the 405 studies identified, 10 randomized controlled trials were included and divided into 3 subgroups according to the proposed dietary intervention. There was a non-significant reduction in systolic blood pressure in the subgroups of mineral replacement (-4.82; 95% CI: -11.36 to 1.73) and complex pattern diets (-3.17; 95% CI: -7.62 to 1.28). Regarding diastolic blood pressure, except for the hyperproteic diet subgroup, all subgroups showed a significant reduction in blood pressure: -4.66 mmHg (95% CI: -9.21 to -0.12) and -4.55 mmHg (95% CI: -7.04 to -2.06) for mineral replacement and complex pattern diets, respectively. Conclusion: Available evidence on the effects of dietary changes on blood pressure in Latin American populations indicates a homogeneous effect of those interventions, although not significant for systolic blood pressure. Samples were small and the quality of the studies was generally low. Larger studies are required to build robust evidence. .

Manejo dietoterápico da obesidade e sua aplicação na população pediátrica: revisão da literatura / A literature review: dietary management of obesity and its application on the pediatric population

Com o aumento da prevalência da obesidade diversas dietas para o tratamento desta doença têm sido descritas. Para a população pediátrica, no entanto, existem poucos estudos avaliando o efeito de diferentes intervenções dietoterápicas. Até o momento, a redução calórica, mais do que a alteração na composição dessas dietas, parece ser o principal fator na redução do peso.

With the increasing prevalence of obesity different diets for the treatment of this disease have been described. For the pediatric population, however, there are few studies evaluation the effect of different dietary interventions. So far, caloric reduction rather than the change in the composition of these diets seem to be the main factor in reducing weight.

Papel del ejercicio físico en las personas con diabetes mellitus / Role of physical exercise in persons presenting with diabetes mellitus

El ejercicio físico constituye uno de los métodos más antiguos empleado en el tratamiento de la diabetes mellitus, y es uno de sus pilares fundamentales junto con la dietoterapia, la educación diabetológica y el empleo de fármacos normoglucemiantes o hipoglucemiantes. Objetives: discutir los aspectos más relevantes del papel del ejercicio físico en las personas con diabetes mellitus. Se recomiendan los ejercicios aerobios en la diabetes mellitus, aunque actualmente el uso de ejercicios de resistencia con pequeñas cargas no está contraindicado en los diabéticos no complicados. Su práctica sistemática trae múltiples beneficios al paciente con diabetes mellitus, entre los que se destaca la mejoría del control metabólico, así como el retraso en la aparición de enfermedades cardiovasculares y la mejoría en el bienestar y la calidad de vida de aquellos que lo practican, entre otros. Además, en los no diabéticos puede ayudar a prevenir la enfermedad. El realizar ejercicio no está exento de riesgos, en particular en aquellos con complicaciones. La hipoglucemia es la complicación observada con mayor frecuencia, situación que puede ser prevenida ajustando el régimen terapéutico (dieta y fármacos). Está contraindicada la actividad física en diabéticos descompensados, porque empeora el estado metabólico. La práctica de deportes extremos de alta peligrosidad no es recomendada en los pacientes con diabetes mellitus. El ejercicio físico es un pilar fundamental en el tratamiento de la diabetes mellitus, incluso en su prevención(AU)

One of the more ancient methods used in treatment of diabetes mellitus and it is one of its fundamental pillars together with dietary therapy, diabetes education and the use of normoglycemic and hypoglycemic drugs. Objetive: to discuss on the more relevant features of the physical exercise role in persons presenting with diabetes mellitus. In cases of diabetes mellitus, the aerobic exercises are recommended, although nowadays the use of resistance exercises with small loads is not contraindicated in non-complicated diabetic patients. Its systemic practice has many benefits for the diabetes mellitus patient including the improvement of metabolic control, as well as a delay in appearance of cardiovascular diseases and the improvement of wellbeing and quality of life of those practicing it. Also, in non-diabetic persona it may to help to prevent the disease. Exercise practice is not free from risks particularly in those with complications. The hypoglycemia is the more frequent observed complication, a situation that may be prevented adjusting the therapeutical regime (diet and drugs). The physical activity is contraindicated in the diabetic persons with decompensation because of it worsen the metabolic status. The practice of high danger sports is not recommended in diabetes mellitus patients. The physical exercise is a fundamental pillar in treatment of diabetes mellitus even in its prevention(AU)

Tratamientos biológicos del autismo y dietas de eliminación / Biological treatments of autism, elimination diets: a critical review

This paper presents some critical considerations regarding the growing adoption, by families, of alternative treatments and diets for the treatment of various disorders like autism in children. Research does not seem to support such practices, with the exception of the relationship between timesoral and vaccines, neurological and cardiac disorders. Issues to consider are pointed out in the need to opt for biological treatments, and the need for families and research teams to work together for the purpose of clarifying such procedures.

El objetivo de este trabajo es presentar consideraciones críticas en relación a la creciente adopción, por parte de las familias de niños con trastornos del desarrollo, de tratamientos alternativos y dietas para reducir los síntomas de diversas alteraciones tales como el autismo, SDAH y otros. Las investigaciones no parecen apoyar tales prácticas, a excepción de la creciente evidencia de la relación entre el timerosal de las vacunas y afecciones cardíacas y neurológicas. Se señalan los elementos a tener en cuenta para optar por los tratamientos biológicos y dietas, junto con insistir en la necesidad de mancomunar esfuerzos entre familias y equipos de investigación para desarrollar estudios que clarifiquen los efectos de tales procedimientos.

Crescimento e sobrevivência de larvas de peixe vermelho (Carassius auratus) alimentadas com microdietas comerciais / Growth and survival of Carassius auratus larvae fed commercial micro diets

Para avaliar o desempenho de dois alimentos comerciais para larvas de peixes ornamentais e analisar o efeito que a suplementação em vitaminas e minerais teria sobre a sobrevivência e o crescimento dessas, foi realizado um ensaio de crescimento de 21 dias, com 4800 larvas de peixe vermelho (Carassius auratus), distribuídas por 24 grupos (200 indivíduos por grupo). Cada grupo foi alojado em tanques de 5L de capacidade, ligados a um sistema de recirculação de água. Quatro grupos foram alocados a um controle de jejum, em que os animais não foram alimentados, e os restantes 20 grupos foram utilizados em cinco tratamentos, em quadruplicado. Em cada um dos cinco tratamentos, os peixes ingeriram uma das seguintes dietas: R (referência), C1 (SERA vipan® baby), C2 (SERA® microgran), C1v e C2v (C1 e C2, respectivamente, reforçadas em vitaminas e minerais). As taxas de sobrevivência e crescimento dos peixes do tratamento R foram maiores que as obtidas nos outros tratamentos (P<0,05). Foram ainda observadas diferenças significativas entre tratamentos relativamente ao comprimento e peso totais. Face aos resultados observados, conclui-se que as duas dietas comerciais, com e sem suplementação, não parecem ser adequadas para o preenchimento das necessidades nutricionais de larvas de peixe vermelho.

A 21-day growth trial was performed to evaluate two ornamental fish larvae commercial diets and the effect of mineral and vitamin supplementation of the same commercial microdiets on growth and survival of goldfish larvae (Carassius auratus). A total of 4,800 larvae were randomly distributed in 24 groups of 200 individuals. Each group was housed in a 5L tank, connected to a recirculating water system. Four groups were assigned to a fastening control. The animals in these groups did not receive any food. The remaining 20 groups were distributed in five treatments, in quadruplicate. The animals of each treatment were fed one of five experimental diets: R (reference), C1 (SERA vipan® baby), C2 (SERA® microgran), C1v, and C2v (C1 and C2, respectively, reinforced with minerals and vitamins). At the end of the trial, high survival and growth rates were observed in R treatment. There were significant differences in total length and total weight among dietary treatments. Considering the high survival and growth rates of goldfish larvae obtained with the reference diet, it can be concluded that the two commercial diets tested, with or without mineral and vitamin supplements, do not seem suitable for feeding goldfish larvae.

Implementação de um programa para evitar possíveis interações fármaco-alimento em pacientes adultos internados em unidades clínicas e cirúrgicas de um hospital universitário / Implementation of a program to prevent possible drug-food interactions in adult patients hospitalized in the clinical and surgical units of a university hospital

Introdução: As interações fármaco-alimento (IFA) são definidas como alterações produzidas nos efeitos terapêuticos de um medicamento em razão da ingestão concomitante de alimento. Objetivo: Identificar prescrições médicas com possíveis IFA dos pacientes internados no Hospital de Clínicas de Porto Alegre (HCPA) e orientar o corpo clínico quanto aos horários adequados de administração dos medicamentos. Métodos: O estudo analisou, entre fevereiro e julho de 2006, 2.645 prescrições de pacientes adultos internados nas unidades clínicas e cirúrgicas do HCPA e que recebiam dieta oral. Resultados: Observou-se que 54,5% (1.442) das prescrições apresentavam potenciais IFA. Nesses casos, as equipes assistenciais recebiam, através de notificação em prontuário médico, informações sobre os medicamentos que necessitavam de intervalo de jejum para garantir sua máxima biodisponibilidade. Conclusão: A alta incidência de prescrições contendo medicamentos possíveis de interagir com os alimentos demonstra a necessidade de um sistema que disponibilize, sistematicamente, as orientações relacionadas à correta administração dos medicamentos.

Background: Drug-food interactions (DFI) are defined as alterations produced in the therapeutic effects of a drug due to concomitant food ingestion. Objective: To identify medical prescriptions with possible DFI in patients hospitalized at Hospital de Clínicas de Porto Alegre (HCPA) and to provide guidance to the clinical staff about the appropriate time for drug administration. Methods: Between February and July 2006, we analyzed 2,645 prescriptions of adult inpatients receiving oral diet. Results: We found that 54.5% (1,442) of the prescriptions had potential DFI. In such cases, the medical staff was receiving information about the drugs that needed a fasting interval to ensure maximum bioavailability by means of notifications in medical records. Conclusions: The high incidence of prescriptions with possible DFI shows the need for a system that provides systematic guidance regarding the adequate administration of drugs.
