Ingestão De Carnes Em Adultos: Estudo De Base Populacional Na Cidade De Campinas, Brasil. Um Estudo Transversal

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Meat is a food with high nutritional density that has significant participation in the Brazilian diet. However, in excess it can cause harm to health. The aim of this study was to analyze the meat intake (g/day) among adults according to sociodemographic, behavioral and health situation characteristics, and to assess the types of meat most consumed. DESIGN AND SETTING: Cross-sectional population-based study conducted in the city of Campinas, São Paulo, Brazil, in 2008 and 2009. METHODS: Two-stage cluster sampling was used. The analysis included 948 adults between 20 and 59 years, who were participants in the Campinas Health Survey. Meat intake was assessed using 24-hour dietary recall. RESULTS: The mean meat intake adjusted for sex and age was 182.3 g (95% CI: 170.6-193.9 g), with significantly lower intake among women, individuals aged 50 years or over, those with the presence of two or more self-reported chronic diseases and those with three or more health complaints. Higher meat intake was found in segments with intermediate monthly family income (between 1 and 3 minimum wages), those with 16 or more appliances per household and those who consumed soft drinks seven days a week. Beef was consumed most frequently (44%) among the meats in the diet, followed by poultry, fish and pork. CONCLUSION: The data from this study reveal high meat intake in the population of Campinas and identify the segments that need to be prioritized for strategies directed towards appropriate meat intake. © 2016, Associacao Paulista de Medicina.

Adolescentes Eutróficos Estão Satisfeitos Com O Seu Peso?

The high prevalence of obesity has led to public policies for combating it. People with normal weight may gain greater awareness of this issue and change their perceptions of their weight. The aim of this study was to evaluate the prevalence of body weight dissatisfaction among normal-weight adolescents, according to demographic and socioeconomic variables, health-related behavior and morbidities. DESIGN AND SETTING: Population-based cross-sectional study that used data from a health survey conducted in the city of Campinas, São Paulo, in 2008-2009. METHODS: The prevalence and prevalence ratios of weight dissatisfaction were estimated according to independent variables, by means of simple and multiple Poisson regression. RESULTS: 573 normal-weight adolescents aged 10 to 19 years (mean age 14.7 years) were analyzed. The prevalence of weight dissatisfaction was 43.7% (95% confidence interval, CI: 37.8-49.8). Higher prevalences of weight dissatisfaction were observed among females, individuals aged 15 to 19 years, those whose households had eight or more domestic appliances, former smokers, individuals who reported alcohol intake and those who had one or more chronic diseases. Lower prevalence of dissatisfaction was observed among adolescents living in substandard housing. Among the normal-weight adolescents, 26.1% wished to lose weight and 17.6% wished to gain weight. CONCLUSION: The results from this study indicate that even when weight is seen to be within the normal range, a high proportion of adolescents express dissatisfaction with their weight, especially females, older adolescents and those of higher socioeconomic level. © 2016, Associacao Paulista de Medicina.

Monitoring training load in beach volleyball players: a case study with an Olympic team

Abstract AIM Describe and compare training load dynamics of two Olympic beach volleyball players. METHODS Two Olympic beach volleyball players participated in this study (specialist defender and blocker: both aged 34 years, holding 14 years of competitive experience, height: 1.74 m and 1.81 m, weight: 69 kg and 65 kg, respectively). Internal training load (ITL), total weekly training load (TWTL), monotony and strain were obtained through the session rating of perceived exertion (session-RPE) for three training mesocycles (10 weeks). Lower limb explosive power was assessed through the counter movement jump (CMJ). RESULTS Mean ITL, TWTL, monotony and strain during the 10-week period were: 370 ± 156; 1997 ± 838; 2.7 ± 1.3; 5621 ± 1802 arbitrary units (AU) (Defender) and 414 ± 153; 2392 ± 892; 2.7 ± 1.1; 6894 ± 3747 (AU) (Blocker). Mean of CMJ height was 47.0 ± 1.3 and 40.3 ± 1.6 cm, for the defender and blocker, respectively. The defender player presented higher ITL in the second (effect size (ES) = 0.90; 92/5/3, likely) and in the third (ES = 0.91; 94/4/2, likely) mesocycles when compared to the first. Monotony raised from the first to the third mesocycle (ES = 2.91; 98/1/1, very likely). Blocker's ITL was higher in the third mesocycle than the first (ES = 1.42. 98/1/1, very likely) and the second (ES = 1.49; 98/1/1, likely) ones. CONCLUSION ITL magnitude increased from the first to the third mesocycle, in both players

Isolation of micropropagated strawberry endophytic bacteria and assessment of their potential for plant growth promotion.

Twenty endophytic bacteria were isolated from the meristematic tissues of three varieties of strawberry cultivated in vitro, and further identified, by FAME profile, into the genera Bacillus and Sphingopyxis. The strains were also characterized according to indole acetic acid production, phosphate solubilization and potential for plant growth promotion. Results showed that 15 strains produced high levels of IAA and all 20 showed potential for solubilizing inorganic phosphate. Plant growth promotion evaluated under greenhouse conditions revealed the ability of the strains to enhance the root number, length and dry weight and also the leaf number, petiole length and dry weight of the aerial portion. Seven Bacillus spp. strains promoted root development and one strain of Sphingopyxis sp. promoted the development of plant shoots. The plant growth promotion showed to be correlated to IAA production and phosphate solubilization. The data also suggested that bacterial effects could potentially be harnessed to promote plant growth during seedling acclimatization in strawberr

Doses cumulativas de iodo radioativo no tratamento do carcinoma diferenciado de tireoide: sabendo a hora de parar

OBJECTIVE: Evaluate the efficacy of cumulative doses (CDs) of 131I-iodide therapy (RIT) in differentiated thyroid cancer (DTC). SUBJECTS AND METHODS: The probability of progressive disease according to CDs was evaluated in patients < 45 years old and &gt; 45 years old and correlated to tumor-node-metastasis (TNM), thyroglobulin values, histological types and variants, age, and zduration of the disease. RESULTS: At the end of a follow-up period of 69 ± 56 months, 85 out of 150 DTC patients submitted to fixed doses RIT had no evidence of disease, 47 had stable disease and 18 had progressive disease. Higher CDs were used in the more aggressive variants (p < 0.0001), higher TNM stages (p < 0.0001), and follicular carcinomas (p = 0.0034). Probability of disease progression was higher with CDs &gt; 600 mCi in patients &gt; 45 years old and with CDs &gt; 800 mCi in patients < 45 years. CONCLUSION: Although some patients may still respond to high CDs, the impact of further RIT should be carefully evaluated and other treatment strategies may be warranted.OBJETIVO: Avaliar a eficácia de doses cumulativas (DCs) da terapia com iodeto-131I (RIT) no câncer diferenciado de tiroide (CDT). SUJEITOS E MÉTODOS: A probabilidade de doença em progressão conforme a DC foi calculada em pacientes com idade < 45 e &gt; 45 anos e correlacionada com o TNM, valores de tiroglobulina sérica, tipos histológicos e variantes, idade e tempo de doença. RESULTADOS: Ao final de um seguimento de 69 ± 56 meses, 85 dos 150 pacientes CDT submetidos a doses fixas de RIT não tinham evidência de doença, 47 tinham doença estável e 18, doença progressiva. DCs mais elevadas foram usadas nas variantes agressivas (p < 0,0001), maior estágio TNM (p < 0,0001) e nos carcinomas foliculares (p = 0,0034). A probabilidade de doença em progressão foi maior com DCs &gt; 600 mCi em pacientes &gt; 45 anos e com DCs &gt; 800 mCi em pacientes < 45 anos. CONCLUSÃO: Apesar de alguns pacientes ainda responderem a altas DCs, o impacto de RITs deve ser cuidadosamente avaliado e outras estratégias terapêuticas devem ser consideradas.80781

Sperm Oxidative Stress Is Detrimental to Embryo Development: A Dose-Dependent Study Model and a New and More Sensitive Oxidative Status Evaluation

Our study aimed to assess the impact of sperm oxidative stress on embryo development by means of a dose-dependent model. In experiment 1, straws from five bulls were subjected to incubation with increasing H2O2 doses (0, 12.5, 25, and 50 μM). Motility parameters were evaluated by Computed Assisted System Analysis (CASA). Experiment 2 was designed to study a high (50 μM) and low dose (12.5 μM) of H2O2 compared to a control (0 μM). Samples were incubated and further used for in vitro fertilization. Analyses of motility (CASA), oxidative status (CellROX green and 2’-7’ dichlorofluorescein diacetate), mitochondrial potential (JC-1), chromatin integrity (AO), and sperm capacitation status (chlortetracycline) were performed. Embryos were evaluated based on fast cleavage (30 h.p.i.), cleavage (D=3), development (D=5), and blastocyst rates (D=8). We observed a dose-dependent deleterious effect of H2O2 on motility and increase on the percentages of positive cells for CellROX green, capacitated sperm, and AO. A decrease on cleavage and blastocyst rates was observed as H2O2 increased. Also, we detected a blockage on embryo development. We concluded that sperm when exposed to oxidative environment presents impaired motility traits, prooxidative status, and premature capacitation; such alterations resulting in embryo development fail

PERFIL DAS PACIENTES DO AMBULATÓRIO DA PÓS GRADUAÇÃO EM VÍDEO HISTEROSCOPIA DA FACULDADE DE CIÊNCIA MÉDICAS DE MINAS GERAIS

RESUMO: A Vídeo Histeroscopia diagnóstica tornou-se uma ferramenta valiosa e importante para o ginecologista ao permitir a avaliação direta da cavidade endometrial e o diagnóstico das doenças proliferativas e ou neoplásicas. Alguns anos atrás, isso só poderia ser realizado através de procedimentos cegos e pouco tolerado pelas pacientes. A Histeroscopia é uma ferramenta cada vez mais utilizada, o que torna a avaliação do perfil epidemiológico das pacientes submetidas a esse procedimento uma nuance importante a ser estudada. Logo, o objetivo desse trabalho é avaliar o perfil epidemiológico das pacientes atendidas pela equipe da Pós-graduação em Vídeo Histeroscopia da FCMMG no ambulatório de vídeo Histeroscopia do Hospital São José em Belo Horizonte. Este trabalho trata-se de estudo retrospectivo realizado com análise de prontuários das pacientes atendidas no período entre outubro e dezembro de 2012, e submetidas a vídeo Histeroscopia ambulatorial durante os módulos do curso de pós graduação. Os exames são realizados em caráter eminentemente ambulatorial pelos pós-graduandos sob supervisão direta dos professores. São usados equipamentos com ópticas de 2,9 mm, camisas diagnósticas e de Betochi, com preferência pela última, meio de distensão soro fisiológico, infundido com bomba Histeromat. A técnica utilizada inclui vaginoscopia, sem uso do espéculo ou pinçamento do colo. O espéculo e a instrumentalização do colo foram utilizados caso houvesse alguma dificuldade no acesso ao colo durante o procedimento. Todos os procedimentos foram realizados sem anestesia. Foram incluídos 203 pacientes encaminhadas a vídeo Histeroscopia ambulatorial. A idade média das pacientes foi de 49,7 anos, variando de 17 a 81 anos. Média de paridade 3,2 filhos e considerando sua prole definida em 70,9 % (144 pacientes). Em relação à escolaridade do grupo estudado, a maioria dos pacientes não tinha concluindo o segundo grau, 67,3%, com apenas 5 pacientes relatando ter completado nível superior (2,6%). Relatavam comorbidades à anamnese 115 pacientes (56,6%), sendo as mais relatadas Hipertensão Arterial Sistêmica (HAS) e diabetes, relatadas por 69 e 20 pacientes respectivamente. Todas as pacientes apresentavam exames ecográficos anteriores. As conclusões principais das ecografias se distribuíam: exame normal 16 pacientes (7,8%), miomas em 58 (28,5%), espessamento endometrial em 67 (33%), pólipos em 66 (32,5%). Após avaliação inicial tiveram indicação confirmada e foram submetidas ao procedimento 185 pacientes. Em ordem de frequência, foram levantadas como principais indicações: espessamento endometrial à ecografia (34,0%), sangramento uterino anormal (28,6%) e infertilidade (10,8%). Todas as pacientes deste grupo concluíram seus exames histeroscópicos e os achados identificados foram: cavidade sem alterações 64 pacientes (34,5%), espessamento focal do endométrio 17 (9,1%), sinéquias 9 (4,8%), pólipos 82 (44,3%) e miomas 13 (7,0%). As pacientes atendidas no referido ambulatório de Histeroscopia tiveram todos os atendimentos iniciais em unidade básica de saúde e em sua ampla maioria tiveram confirmada a indicação para o procedimento. Mesmo realizados dentro do contexto de ensino, a efetiva realização do exame com definição diagnóstica para a cavidade uterina foi possível para todo o grupo estudado. Seus achados apontam para uma significativa diminuição da necessidade de procedimentos cirúrgicos hospitalares uma vez que um grande número de pacientes apresentaram exames normais ou alterações focais que tem seu diagnóstico e tratamento completamente efetivados, através de biópsias e pequenas intervenções realizadas durante a Histeroscopia ambulatorial.PALAVRAS-CHAVE: perfil epidemiológico, vídeo Histeroscopia ambulatorial, pós graduaçã
