Médici, André Cezar;
Saúde e Sociedade , 1992, DOI: 10.1590/S0104-12901992000200004
Abstract: o objetivo deste texto é discutir algumas tendências da medicina, a partir da análise de sua evolu??o ao longo do período que, do ponto de vista histórico, caracteriza a modernidade e sua crise. a medicina é, desta forma, avaliada segundo as óticas da economia, das rela??es do poder, do desenvolvimento científico e tecnológico e da linguagem. a quest?o da economia remete a análise para a quest?o dos mercados e das formas de concorrência e crescimento capitalista assumidas pela medicina ao longo de sua trajetória a quest?o do poder remete a análise das institui??es de saúde e das formas de organiza??o do trabalho no setor. a quest?o da ciência procura avaliar o espectro de formas de produ??o do conhecimento no setor, bem como seus impactos na cobertura e na eqüidade do acesso às condi??es de saúde e assistência médica. por fim, a quest?o da linguagem marca a análise de como a tecnifica??o extrema da medicina vai progressivamente caracterizando campos semanticos próprios a cada especialidade, dificultando o uso de teorias totalizadoras para explicar as rela??es internas no seio da produ??o de conhecimento no setor.
Dietary Supplementation with Probiotic Strain Improves Immune-Health in Aged Mice  [PDF]
Verónica Molina, Marta Médici, Julio Villena, Graciela Font, María Pía Taranto
Open Journal of Immunology (OJI) , 2016, DOI: 10.4236/oji.2016.63008
Abstract: Ageing is associated with several anatomical and physiological changes of the organism, and the increase in global elderly population promotes the research to develop strategies to improve their quality of life. In this work, we characterized the immunological alterations naturally produced during aging in a mice model, and evaluated the effect of probiotic Lactobacillus (L.) rhamnosus CRL1505 administration on those immunological parameters. We demonstrated that L. rhamosus CRL1505 was able to improve peritoneal macrophages phagocytic activity, and the number of intestinal IgA+ cells in aged mice, reaching values of those parameters similar to young adult mice. The results of this work indicate that is plausible that the immunobiotic CRL1505 strain may find applications as a beneficial immunomodulator in aging to reinforce the intestinal and systemic immunity. The immune modulation in aging induced by L. rhamnosus CRL1505 could lead to the development of new strategies for functional foods specifically tailored for the elderly.

Claus, Marlise Pompeo;Alfieri, Alice Fernandes;Médici, Kerlei Cristina;Lunardi, Michele;Alfieri, Amauri Alcindo;
Brazilian Journal of Microbiology , 2007, DOI: 10.1590/S1517-83822007000300019
Abstract: bovine herpesvirus 5 (bohv-5) is an important cause of meningoencephalitis in young and adult cattle. the multiple etiology of neurological disturbances in cattle makes the quick and conclusive diagnosis of bohv-5 infection important for animal and public health, mainly because of herbivore rabies that is endemic in brazilian cattle herds. the objective of this retrospective study was to use a multiplex-polymerase chain reaction (multiplex-pcr) for bohv-5 and bohv-1 glycoprotein c gene detection from stored central nervous system (cns) tissue fragments of cattle with neurological clinical signs. forty-seven frozen cns samples of young and adult cattle from 31 herds in three brazilian geographical regions (south, southeast, and center-west) were evaluated. eighteen (38.3%) of these cns samples were bohv-positive by virus isolation in cell culture. by multiplex-pcr 30 (63.8%) cns samples were bohv-5 positive. all 18 positive samples by virus isolation were confirmed as bohv-5 by the multiplex-pcr, that provided a increase of 25.5% (12/47) in the bohv-5 diagnosis rate. bohv-1 was not detected in any cns sample. this retrospective study demonstrated the wide regional distribution of bohv-5 infection in brazilian cattle herds since positive results were obtained in cns samples of cattle with neurological disease from paraná, s?o paulo, minas gerais, mato grosso, and mato grosso do sul states.

Abstract: crushed stone mining is the third largest mining economy in brazil, where almost half is produced in the sao paulo metropolitan region. the segment registers the highest number of accidents among the extractive industries, which justifies the concern with workers’ health and safety and the importance of controlling occupational hazards. since 2002, the nr-22 standard (nr-22: occupational health and safety in mining) makes compulsory the elaboration of a risk management program that identifies risks and establishes control measures. considering the crushed stone mining industry’s importance to the state, this paper evaluates and discusses the risks identified in unit operations during the production process of crushed stone in an open pit mine in order to propose control measures for the development of the risk management program. although this study refers to a specific quarry, it can be applied to other mines from the same sector, since some considerations are made regarding differences in manufacturing processes. the research was based on the identification of the main risks associated with drilling, blasting, load & haulage, crushing and screening through field measurements of some hazardous agents, together with company reports. the results contributed to the choice of the appropriate control measures for the improvement of workers’ health and safety conditions.

Abstract: objective: the objective of this study was to assess the health and nutritional status of children under five years of age and to associate the quality of the foods consumed with the bolsa família program in a city located in the brazilian semi-arid region. method: a total of 189 children from a sample of 411 households in the city of jo?o camara (rn) were assessed. weight and height were measured and socioeconomic and food habits were determined with the use of questionnaires. the nutritional status of the children was determined with the weight-for-age, height-for-age and weight-for-height indicators. univariate analyses were done and bivariate and multivariate logistic regression models were constructed to test the hypothesis of the study. results: of the studied children, 4.3% were underweight, 9.9% were stunted and 14.0% were overweight. the nutritional status of children whose families receive the bolsa família financial aid was not significantly different from those whose families do not receive the aid. in both groups, the consumption of fruits and non-starchy vegetables was low and similar. children from families who receive the aid were 3 times more likely to eat junk food (or 3.06 - ci 1.35-6.95). conclusion: the food intake patterns of this population indicate that they are at food and nutritional risk. health professionals need to intervene in order to promote healthier eating habits.
Alimentos funcionales probióticos
María Pía Taranto,Marta Médici,Graciela Font Valdez
Química Viva , 2005,
Abstract: La demanda del mercado nacional e internacional ha impulsado en los últimos a os una nueva línea de alimentos funcionales probióticos, productos alimenticios que, además de su valor nutritivo intrínseco, ayudan a mantener el estado de salud general del organismo y a la vez pueden tener un efecto benéfico adicional, terapéutico o preventivo en el huésped. El concepto de alimentos funcionales (AF) tiene su origen en una mayor comprensión de las bases moleculares de la relación existente entre alimentación y salud y la posibilidad de contar con reguladores biológicos (donde las bacterias lácticas juegan un papel protagónico) que disminuyan el riesgo de contraer enfermedades. Los microorganismos comúnmente empleados como probióticos se encuentran disponibles comercialmente a través de laboratorios o industrias alimenticias a nivel internacional así como en colecciones de cultivos. Sin embargo, muchos de ellos con propiedades particulares, están protegidos mediante patentes o licencias. La colección de cultivo de CERELA cuenta con un banco de bacterias probióticas para diferentes estudios tales como producción de vitaminas, regulación lipídica, inmunomodulación, protección del tracto gastrointestinal, etc. En esta revisión del tema se describen la disminución de intolerancia a la lactosa uno de los efectos probióticos de las BAL mejor documentados- y otros potencialmente benéficos, por ejemplo, propiedades inmunomoduladoras, capacidad hipolipemiante, inhibición de patógenos intestinales, propiedad protectora de la mucosa gástrica, actividad antagónica contra rotavirus, prevención de reacciones alérgicas y disminución del riesgo de enterocolitis necrotizante neonatal. La investigación científico-tecnológica de estas propiedades permitirá optimizar los procesos de elaboración de alimentos funcionales que contengan este tipo de cultivo lácticos, así como conocer los mecanismos por los cuales estas bacterias ejercen su efecto benéfico en el huésped, lo que reforzará la confianza de la comunidad médica y el público en general en el uso de estos bio-reguladores que se encuentran a la vanguardia en el mercado internacional de alimentos
