- Antimicrobial drug resistance of Campylobacter spp and Salmonella enterica: national data in food producing animals and food of animal originPublication . Clemente, L.; Correia, I.; Ferreira, E.; Manageiro, V.; Jones-Dias, D.; Albuquerque, T.; Themudo, P.; Rocha, T.; Tavares, A.; Geraldes, M.; Barahona, M.J.; Caniça, M.Campylobacter spp and Salmonella enterica are the two most common causes of bacterial foodborne illnesses in humans in developed countries, being food producing animals one the main reservoirs. Antimicrobial susceptibility testing was determined through Minimum Inhibitory Concentration, in 448 isolates of Campylobacter spp recovered from broiler ceca at slaughter (n=351) and broiler carcasses (n=97); and 1600 isolates of S. enterica feed (n=43) and food products of animal origin (n=527). Screening and identification of beta-lactamase and plasmid-mediated quinolone resistance (PMQR) genes were performed by PCR and sequencing. The highest level of resistance in Campylobacter spp isolates recovered from broilers and carcasses was recorded to ciprofloxacin, followed by tetracycline, erythromycin and streptomycin. Four isolates of Campylobacter coli were resistant to gentamicin.
- Cardiovascular risk profile of high school students: A cross-sectional studyPublication . Rocha, T.; Rocha, E.; Alves, A.C.; Medeiros, A.M.; Francisco, V.; Silva, S.; Mendes Gaspar, I.; Rato, Q.; Bourbon, M.INTRODUCTION: Disease prevention should begin in childhood and lifestyles are important risk determinants of cardiovascular disease. Awareness and monitoring of risk is essential in preventive strategies. AIM: To characterize cardiovascular risk and the relationships between certain variables in adolescents. METHODS: In a cross-sectional study, 854 adolescent schoolchildren were surveyed, mean age 16.3±0.9 years. Data collection included questionnaires, physical examination, charts for 10-year relative risk of mortality, and biochemical assays. In the statistical analysis continuous variables were studied by the Student's t test and categorical variables by the chi-square test and Fisher's exact test, and each risk factor was entered as a dependent variable in logistic regression analysis. RESULTS: Physical activity was insufficient in 81% of students. The daily consumption of soup, salad or vegetables, and fruit was, respectively, 37%, 39% and 21%. A minority (6%) took ≤3 and 77% took ≥5 meals a day. The prevalence of each risk factor was as follows: overweight 16%; smoking 13%; hypertension 11%; impaired glucose metabolism 9%; hypertriglyceridemia 9%; and hypercholesterolemia 5%. Out-of-school physical activity, hypertension and overweight were more prevalent in males (p<0.001). Females had higher levels of cholesterol (p<0.005) and triglycerides (p<0.001). A quarter of the adolescents had a relative risk score for 10-year cardiovascular mortality of ≥2. Overweight showed a positive association with blood pressure, changes in glucose metabolism and triglycerides, and a negative association with number of daily meals. CONCLUSIONS: The results demonstrate the need for action in providing and encouraging healthy choices for adolescents, with an emphasis on behavioral and lifestyle changes aimed at individuals, families and communities
