The present work aimed to evaluate the effectiveness of whole grain consumption in preventing colorectal cancer. A systematic review with meta-analysis of 11 cohort studies was carried out. The age group of the population studied (1,719,590 participants) was between 25 and 76 years of age. The review evaluated the relative risks with the Cox proportional hazard model. The period of study varied from 6 to 16 years, where 7,745 persons developed colorectal cancer during the follow-up period. In the multivariate analysis, the highest quintile relative risk was 0.94 (95% confidence interval, 0.85-1.03), whereas that for the lowest quintile was 0.96 (95% confidence interval, 0.88-1.04). The location of tumors was also evaluated, with tumors in the colon demonstrating a relative risk of 0.93 (95% confidence interval, 0.83-1.02) and tumors in the recto a relative risk equal to 0.89 (95% confidence interval, 0.79-1.00). In this multivariate analysis, consumption of whole grains was inversely associated with the risk of developing colorectal cancer.

Purpose: To identify risk groups for oropharyngeal dysphagia in hospitalized patients in a university hospital. Methods: The study was design as an exploratory cross-sectional with quantitative data analysis. The researched population consisted of 32 patients admitted to the medical clinic at the university hospital. Patient history data were collected, followed by a universal swallowing screening which included functional feeding assessment, to observe clinical signs and symptoms of dysphagia, and assessment of nutritional status through anthropometric data and laboratory tests. Results: Of the total sample, the majority of patients was male over 60 years. The most common comorbidities related to patients with signs and symptoms of dysphagia were chronic obstructive pulmonary disease, systemic arterial hypertension, congestive heart failure, diabetes mellitus and acute myocardial infarction. The food consistency that showed higher presence of clinical signs of aspiration was pudding and the predominant sign was wet voice. Conclusion: There is a high incidence of risk for oropharyngeal dysphagia in hospitalized patients and an even higher rate of hospitalized patients with nutritional deficits or already malnourished. Hospitalized patients with respiratory diseases, chronic obstructive pulmonary disease, congestive heart failure and patients with xerostomia were indicated as risk group for oropharyngeal dysphagia.

BackgroundThe risk factors that characterize metabolic syndrome (MetS) may be present in childhood and adolescence, increasing the risk of cardiovascular disease in adulthood.ObjectiveEvaluate the prevalence of MetS and the importance of its associated variables, including insulin resistance (IR), in children and adolescents in the city of Guabiruba-SC, Brazil.MethodsCross-sectional study with 1011 students (6-14 years, 52.4% girls, 58.5% children). Blood samples were collected for measurement of biochemical parameters by routine laboratory methods. IR was estimated by the HOMA-IR index, and weight, height, waist circumference and blood pressure were determined. Multivariate logistic regression models were used to examine the associations between risk variables and MetS.ResultsThe prevalence of MetS, IR, overweight and obesity in the cohort were 14%, 8.5%, 21% and 13%, respectively. Among students with MetS, 27% had IR, 33% were overweight, 45.5% were obese and 22% were eutrophic. IR was more common in overweight (48%) and obese (41%) students when compared with eutrophic individuals (11%; p = 0.034). The variables with greatest influence on the development of MetS were obesity (OR = 32.7), overweight (OR = 6.1), IR (OR = 4.4; p ≤ 0.0001 for all) and age (OR = 1.15; p = 0.014).ConclusionThere was a high prevalence of MetS in children and adolescents evaluated in this study. Students who were obese, overweight or insulin resistant had higher chances of developing the syndrome.

Evidence-based strategies to improve the hepatitis B virus (HBV) vaccination coverage rates might help to reduce the burden caused by co-infection with HBV and human immunodeficiency virus (HIV). In this study, the aim was to evaluate the vaccination coverage and immunity against HBV among HIV-infected individuals in South Brazil, and identify factors that are associated with compliance patterns and antibody reactivity. Three hundred HIV-infected men and women were included in this survey. The patients answered a standardized questionnaire, and vaccination cards were checked in order to assess hepatitis B vaccine status. A blood sample was collected for quantitative determination of antibody to hepatitis B virus surface antigen (anti-HBs). Participants were also evaluated for their CD4 cell count and HIV viral load. The overall vaccination coverage of HBV vaccination found in this study (57.4%) was lower than that was previously reported in South Brazil. Anti-HBs levels >10IU/L were observed in 47.0% of the studied population. A significant inequality in the coverage rates and antibody reactivity was found in favor of patients with better economic status. In conclusion, the results indicate the need for improvement in the HBV vaccination coverage among HIV carriers, in particular focusing on low-income individuals.

Three glycolipids (1-3) were isolated from the basidiolichen Dictyonema glabratum. Their carbohydrate and lipid components were structurally characterized using 1D 1H and 13C and 2D NMR spectroscopy, complemented by mass spectrometry, as were the carbohydrate moieties formed on saponification. These were O-alpha-D-Galp-(1''-->6')-O-beta-D-Galp-(1'<-->1)-2, 3-diacyl-D-glycerol (2) and two others not previously found in lichens, O-beta-D-Galp-(1'<-->1)-2,3-diacyl-D-glycerol (1) and O-alpha-D-Galp-(1'''-->6'')-O-alpha-D-Galp-(1' '-->6')-O-beta-D-Galp-(1'<-->1)-2,3-diacyl-D-glycerol (3). Each was saponified to give the free carbohydrates and its fatty acid methyl esters. The most abundant fatty acid esters in 1-3 was palmitic C16:0, but there was a wide variation of ester composition. Others present were C8:0 and C14:0 in 1, C14:0, C15:0, C17:0, C18:0, C18:1 (oleic), C18:2 (linoleic), C22:0, and C24:0 in 2, and C8:0, C14:0, C18:0, C18:1 (oleic), C18:2 (linoleic), and C18:3 (linolenic) in 3. As in ascolichens, the glycolipids appear to arise from the phycobiont.

Introduction: This study aimed to estimate the prevalence of human immunodeficiency virus (HIV) infection among prison inmates and to define the behavioral profile of infected individuals. Methods: In total, 147 individuals were interviewed and provided biological material. The study population consisted of male individuals who presented at the health unit of the Florianopolis State Penitentiary. Results: The prevalence of HIV infection was 2.1% (95% confidence interval, 0.4-5.8). With respect to the behavioral profile of individuals, no variable showed statistical significance. Conclusions: The prevalence of HIV infection among prison inmates was higher than that reported for the general population.

RESUMO:Os extratos obtidos pela maceração em CHCl 3 /MeOH (2:1) de 8 amostras de espécies medicinais e 11 amostras comerciais de chás foram analisados por cromatografi a em camada delgada (CCD). Glicolipídios foram detectados em todas as amostras, porém com diferenças qualiquantitativas. Para as plantas medicinais, a maior concentração de glicolipídios foi detectada em Lippia alba e Cymbopogon citratus, enquanto em amostras comerciais, o melhor perfi l glicolipídico foi encontrado nos extratos de C. citratus e Baccharis trimera.Unitermos: Glicolipídios, plantas medicinais, cromatografi a em camada delgada.ABSTRACT: "Screening of glycolipids in medicinal plants". The extracts obtained by maceration in CHCl 3 /MeOH (2:1) of 8 medicinal plants and 11 commercial samples (tea bags) were analysed by thin-layer chromatography. Glycolipids were detected in all the samples, with qualitative and quantitative differences. For the medicinal plants, the highest concentrations were detected in Lippia alba and Cymbopogon citratus. For the commercial samples, the best glycolipidic profi les were found in C. citratus and Baccharis trimera extracts.
