Gazpacho consumption is associated with lower blood pressure and reduced hypertension in a high cardiovascular risk cohort. Cross-sectional study of the PREDIMED trial

Hypertension is a major public health problem and a leading cause of death and disability in both developed and developing countries, affecting onequarter of the world"s adult population. Our aim was to evaluate whether the consumption of gazpacho, a Mediterranean vegetable-based cold soup rich in phytochemicals, is associated with lower blood pressure (BP) and/or reduced prevalence of hypertension in individuals at high cardiovascular risk. Methods and results: We selected 3995 individuals (58% women, mean age 67 y) at high cardiovascular risk (81% hypertensive) recruited into the PREDIMED study. BP, weight, and dietary and physical activity data were collected. In multivariate linear regression analyses, after adjustment, moderate and high gazpacho consumption categories were associated with reduced mean systolic BP of 1.9 mm Hg [95% confidence interval (CI): 3.4; 0.6] and 2.6 mm Hg (CI: 4.2; 1.0), respectively, and reduced diastolic BP of 1.5 mm Hg (CI: 2.3; 0.6) and 1.9 mm Hg (CI: 2.8; 1.1). By multiple-adjusted logistic regression analysis, gazpacho consumption was associated with a lower prevalence of hypertension, with OR Z 0.85 (CI: 0.73; 0.99) for each 250 g/week increase and OR Z 0.73 (CI: 0.55; 0.98) for high gazpacho consumption groups compared to the no-consumption group. Conclusions: Gazpacho consumption was inversely associated with systolic and diastolic BP and prevalence of hypertension in a cross-sectional Mediterranean population at high cardiovascular risk. The association between gazpacho intake and reduction of BP is probably due to synergy among several bioactive compounds present in the vegetable ingredients used to make the recipe.

Meta-analysis : subclinical thyroid dysfunction and the risk for coronary heart disease and mortality

Rapport de synthèse : Description : ce travail de thèse évalue de façon systématique les études sur l'association entre les dysfonctions thyroïdiennes infracliniques d'une part, et la maladie coronarienne et la mortalité d'autre part. Les hypothyroïdies infracliniques affectent environ 4-5% de la population adulte alors que la prévalence de l'hyperthyroïdie infraclinique est inférieure (environ 1%). L'éventuelle association entre elles pourrait justifier un dépistage systématique des dysfonctions thyroïdiennes infracliniques. Les précédentes études sur l'association entre l'hypothyroïdie infraclinique et la maladie coronarienne ont donné des résultats conflictuels. La parution de nouveaux articles récents basés sur de grandes cohortes prospectives nous a permis d'effectuer une méta-analyse basée uniquement sur des études de cohorte prospectives, augmentant ainsi la validité des résultats. Résultats: 10 des 12 études identifiées pour notre revue systématique sont basées sur des cohortes issues de la population générale («population-based »), regroupant en tout 14 449 participants. Ces 10 études examinent toutes le risque associé à l'hypothyroïdie infraclinique (avec 2134 événements coronariens et 2822 décès), alors que 5 étudient également le risque associé à l'hyperthyroïdie infraclinique (avec 1392 événements coronariens et 1993 décès). En utilisant un modèle statistique de type random-effect model, le risque relatif [RR] lié à l'hypothyroïdie infraclinique pour la maladie coronarienne est de 1.20 (intervalle de confiance [IC] de 95%, 0.97 à 1.49). Le risque diminue lorsque l'on regroupe uniquement les études de meilleure qualité (RR compris entre 1.02 et 1.08). Il est plus élevé parmi les participants de moins de 65 ans (RR, 1.51 [IC, 1.09 à 2.09] et 1.05 [IC, 0.90 à 1.22] pour les études dont l'âge moyen des participants est >_ 65 ans). Le RR de la mortalité cardiovasculaire est de 1.18 (IC, 0.98 à 1.42) et de 1.12 (IC, 0.99 à 1.26) pour la mortalité totale. En cas d'hyperthyroïdie infraclinique, les RR de la maladie coronarienne sont de 1.21 (IC, 0.88 à 1.68), de 1.19 (IC, 0.81 à 1.76) pour la mortalité cardiovasculaire, et de 1.12 (IC, 0.89 à 1.42) pour la mortalité totale. Conclusions et perspectives : nos résultats montrent que les dysfonctions thyroïdiennes infracliniques (hypothyroïdie et hyperthyroïdie infracliniques) représentent un facteur de risque modifiable, bien que modéré, de la maladie coronarienne et de la mortalité. L'efficacité du traitement de ces dysfonctions thyroïdiennes infracliniques doit encore être prouvée du point de vue cardiovasculaire et de la mortalité. Il est nécessaire d'effectuer des études contrôlées contre placebo avec le risque cardiovasculaire et la mortalité comme critères d'efficacité, avant de pouvoir proposer des recommandations sur le dépistage des ces dysfonctions thyroïdiennes dans la population adulte.

Extracellular-signal-regulated kinase 5 modulates the antioxidant response by transcriptionally controlling Sirtuin 1 expression in leukemic cells.

Cancer cell metabolism differs from that of non-transformed cells in the same tissue. This specific metabolism gives tumor cells growing advantages besides the effect in increasing anabolism. One of these advantages is immune evasion mediated by a lower expression of the mayor histocompatibility complex class I molecules. The extracellular-signal-regulated kinase-5 regulates both mayor histocompatibility complex class I expression and metabolic activity. However, the mechanisms underlying are largely unknown. We show here that extracellular-signal-regulated kinase-5 regulates the transcription of the NADH(+)-dependent histone deacetylase silent mating type information regulation 2 homolog 1 (Sirtuin 1) in leukemic Jurkat T cells. This involves the activation of the transcription factor myocyte enhancer factor-2 and its binding to the sirt1 promoter. In addition, extracellular-signal-regulated kinase-5 is required for T cell receptor-induced and oxidative stress-induced full Sirtuin 1 expression. Extracellular-signal-regulated kinase-5 induces the expression of promoters containing the antioxidant response elements through a Sirtuin 1-dependent pathway. On the other hand, down modulation of extracellular-signal-regulated kinase-5 expression impairs the anti-oxidant response. Notably, the extracellular-signal-regulated kinase-5 inhibitor BIX02189 induces apoptosis in acute myeloid leukemia tumor cells without affecting T cells from healthy donors. Our results unveil a new pathway that modulates metabolism in tumor cells. This pathway represents a promising therapeutic target in cancers with deep metabolic layouts such as acute myeloid leukemia.

Concurrent or Sequential Adjuvant Letrozole and Radiotherapy after Conservative Surgery for Early-stage Breast Cancer: Long-term Results of the Cohort Phase 2 Randomized Trial

Purpose/Objective(s): Letrozole radiosensitizes breast cancer cells in vitro. In clinical settings, no data exist for the combination of letrozole and radiotherapy. We assessed concurrent and sequential radiotherapy and letrozole in the adjuvant setting.Materials/Methods: The present study is registered with ClinicalTrials.gov, number NCT00208273. This Phase 2 randomized trial was undertaken in two centers in France and one in Switzerland between January 12, 2005, and February 21, 2007. One hundred fifty postmenopausal women with early-stage breast cancer were randomly assigned after conserving surgery to either concurrent radiotherapy and letrozole (n = 75) or sequential radiotherapy and letrozole (n = 75). Randomization was open label with a minimization technique, stratified by investigational centers, chemotherapy (yes vs. no), radiation boost (yes vs. no), and value of radiation-induced lymphocyte apoptosis (#16% vs. .16%). The whole breast was irradiated to a total dose of 50 Gy in 25 fractions over 5 weeks. In the case of supraclavicular and internal mammary node irradiation, the dose was 44 - 50 Gy. Letrozole was administered orally once daily at a dose of 2 - 5 mg for 5 years (beginning 3 weeks pre-radiotherapy in the concomitant group, and 3 weeks postradiotherapy in the sequential group). The primary endpoint was the occurrence of acute (during and within 6 weeks of radiotherapy) and late (within 2 years) radiation-induced Grade 2 or worse toxic effects of the skin and lung (functional pulmonary test and lung CT-scan). Analyses were by intention-to-treat. The long-term follow-up after 2 years was only performed in Montpellier (n = 121) and evaluated skin toxicity (clinical examination every 6 months), lung fibrosis (one CT-scan yearly), cosmetic outcome.Results: All patients were analyzed apart from 1 in the concurrent group who withdrew consent before any treatment.Within the first 2 years (n = 149), no lung toxicity was identified by CT scan and no modification from baseline was noted by the lung diffusion capacity test. Two patients in each group had Grade 2 or worse late effects (both radiation-induced subcutaneous fibrosis [RISF]). After 2 years (n = 121), and with a median follow-up of 50 months (38-62), 2 patients (1 in each arm) presented a Grade 3 RISF. No lung toxicity was identified by CT scan. Cosmetic results (photographies) and quality of life was good to excellent. All patients who had Grade 3 subcutaneous fibrosis had an RILA value of 16% or less, irrespective of the sequence with letrozole.Conclusions:With long-term follow-up, letrozole can be safely delivered shortly after surgery and concomitantly with radiotherapy.

Cigarette, cigar, and pipe smoking and the risk of head and neck cancers: pooled analysis in the International Head and Neck Cancer Epidemiology Consortium.

Cigar and pipe smoking are considered risk factors for head and neck cancers, but the magnitude of effect estimates for these products has been imprecisely estimated. By using pooled data from the International Head and Neck Cancer Epidemiology (INHANCE) Consortium (comprising 13,935 cases and 18,691 controls in 19 studies from 1981 to 2007), we applied hierarchical logistic regression to more precisely estimate odds ratios and 95% confidence intervals for cigarette, cigar, and pipe smoking separately, compared with reference groups of those who had never smoked each single product. Odds ratios for cigar and pipe smoking were stratified by ever cigarette smoking. We also considered effect estimates of smoking a single product exclusively versus never having smoked any product (reference group). Among never cigarette smokers, the odds ratio for ever cigar smoking was 2.54 (95% confidence interval (CI): 1.93, 3.34), and the odds ratio for ever pipe smoking was 2.08 (95% CI: 1.55, 2.81). These odds ratios increased with increasing frequency and duration of smoking (Ptrend ≤ 0.0001). Odds ratios for cigar and pipe smoking were not elevated among ever cigarette smokers. Head and neck cancer risk was elevated for those who reported exclusive cigar smoking (odds ratio = 3.49, 95% CI: 2.58, 4.73) or exclusive pipe smoking (odds ratio = 3.71, 95% CI: 2.59, 5.33). These results suggest that cigar and pipe smoking are independently associated with increased risk of head and neck cancers.

Gazpacho consumption is associated with lower blood pressure and reduced hypertension in a high cardiovascular risk cohort. Cross-sectional study of the PREDIMED trial

Hypertension is a major public health problem and a leading cause of death and disability in both developed and developing countries, affecting onequarter of the world"s adult population. Our aim was to evaluate whether the consumption of gazpacho, a Mediterranean vegetable-based cold soup rich in phytochemicals, is associated with lower blood pressure (BP) and/or reduced prevalence of hypertension in individuals at high cardiovascular risk. Methods and results: We selected 3995 individuals (58% women, mean age 67 y) at high cardiovascular risk (81% hypertensive) recruited into the PREDIMED study. BP, weight, and dietary and physical activity data were collected. In multivariate linear regression analyses, after adjustment, moderate and high gazpacho consumption categories were associated with reduced mean systolic BP of 1.9 mm Hg [95% confidence interval (CI): 3.4; 0.6] and 2.6 mm Hg (CI: 4.2; 1.0), respectively, and reduced diastolic BP of 1.5 mm Hg (CI: 2.3; 0.6) and 1.9 mm Hg (CI: 2.8; 1.1). By multiple-adjusted logistic regression analysis, gazpacho consumption was associated with a lower prevalence of hypertension, with OR Z 0.85 (CI: 0.73; 0.99) for each 250 g/week increase and OR Z 0.73 (CI: 0.55; 0.98) for high gazpacho consumption groups compared to the no-consumption group. Conclusions: Gazpacho consumption was inversely associated with systolic and diastolic BP and prevalence of hypertension in a cross-sectional Mediterranean population at high cardiovascular risk. The association between gazpacho intake and reduction of BP is probably due to synergy among several bioactive compounds present in the vegetable ingredients used to make the recipe.

Treatment modification in human immunodeficiency virus-infected individuals starting combination antiretroviral therapy between 2005 and 2008.

BACKGROUND: Adverse effects of combination antiretroviral therapy (CART) commonly result in treatment modification and poor adherence. METHODS: We investigated predictors of toxicity-related treatment modification during the first year of CART in 1318 antiretroviral-naive human immunodeficiency virus (HIV)-infected individuals from the Swiss HIV Cohort Study who began treatment between January 1, 2005, and June 30, 2008. RESULTS: The total rate of treatment modification was 41.5 (95% confidence interval [CI], 37.6-45.8) per 100 person-years. Of these, switches or discontinuations because of drug toxicity occurred at a rate of 22.4 (95% CI, 19.5-25.6) per 100 person-years. The most frequent toxic effects were gastrointestinal tract intolerance (28.9%), hypersensitivity (18.3%), central nervous system adverse events (17.3%), and hepatic events (11.5%). In the multivariate analysis, combined zidovudine and lamivudine (hazard ratio [HR], 2.71 [95% CI, 1.95-3.83]; P < .001), nevirapine (1.95 [1.01-3.81]; P = .050), comedication for an opportunistic infection (2.24 [1.19-4.21]; P = .01), advanced age (1.21 [1.03-1.40] per 10-year increase; P = .02), female sex (1.68 [1.14-2.48]; P = .009), nonwhite ethnicity (1.71 [1.18-2.47]; P = .005), higher baseline CD4 cell count (1.19 [1.10-1.28] per 100/microL increase; P < .001), and HIV-RNA of more than 5.0 log(10) copies/mL (1.47 [1.10-1.97]; P = .009) were associated with higher rates of treatment modification. Almost 90% of individuals with treatment-limiting toxic effects were switched to a new regimen, and 85% achieved virologic suppression to less than 50 copies/mL at 12 months compared with 87% of those continuing CART (P = .56). CONCLUSIONS: Drug toxicity remains a frequent reason for treatment modification; however, it does not affect treatment success. Close monitoring and management of adverse effects and drug-drug interactions are crucial for the durability of CART.

Atraso do amadurecimento de banana 'Maçã' pelo 1-MCP, aplicado previamente à refrigeração

O objetivo deste trabalho foi avaliar o efeito de diferentes períodos de exposição da banana 'Maçã' a 50 ppb de 1-MCP (0; 3; 6; 9; 12 e 24 horas) sobre sua vida pós-colheita e qualidade. Após exposição ao 1-MCP, os frutos verde-maturos foram armazenados por 30 dias em câmaras com temperatura de 13ºC ± 0,5 e umidade relativa de 95%. Em seguida, as bananas foram armazenadas à temperatura de 20ºC ± 1, até amarelecimento completo da casca. A exposição de banana 'Maçã' a 50 ppb de 1-MCP, por 9 horas, retardou em 7 dias o seu amadurecimento, em comparação a frutos não expostos ao 1-MCP, após 30 dias de armazenamento refrigerado (13ºC), sem prejuízos à sua aparência e composição química. A exposição de banana 'Maçã' a 50 ppb de 1-MCP, por 3 e 6 horas, não estendeu sua vida pós-colheita, tampouco alterou sua composição química. Embora a exposição de banana 'Maçã' a 50 ppb de 1-MCP, por 12 e 24 horas, tenha retardado o seu amadurecimento, promoveu alterações indesejáveis na casca do fruto. Logo, a aplicação de 50 ppb de 1-MCP, por 9 horas, antes da refrigeração, constitui-se numa alternativa viável para prolongar o período de comercialização da banana.

Simulação computacional aplicada ao desenvolvimento de embalagens para bananas

Este trabalho propõe um método de projeto de embalagem para produtos hortícolas, buscando uma otimização integrada dos aspectos geométricos, estruturais e térmicos, ligados à facilitação do resfriamento e armazenamento refrigerado. Para o dimensionamento e otimização estrutural, foi utilizado o Método dos Elementos Finitos implementado pelo programa ANSYS, obtendo-se oito modelos virtuais de embalagens, com 10% e 14% de área efetiva de aberturas e geometria quadrada, retangular e circular. Para o desenvolvimento dos experimentos, que avaliaram a relação da área de aberturas com o tempo de sete-oitavos de resfriamento, foram construídos protótipos de tábuas de madeira (Pinnus elliotti) de reflorestamento. Nas embalagens, foram acondicionados aproximadamente 13 kg de banana variedade Nanica (Musa cavendishii, cultivar nanica), resfriada num túnel de ar forçado (vazão de ar de 0,32 m³ s-1, temperatura de 8,0±1,2ºC e umidade relativa de 84,5±2,6%). O tempo de resfriamento também foi comparado com aquele obtido quando a mesma quantidade de frutas foi resfriada em embalagens de papelão (2,5% de área efetiva de abertura) e madeira (18% de área efetiva de abertura). Os resultados demonstraram que, entre os protótipos propostos, não houve diferença significativa no tempo de resfriamento dos frutos acondicionados nas embalagens desenvolvidas, sendo o tempo médio de resfriamento de 40,71±2,81 min. Na comparação com as embalagens de papelão e madeira, houve diferenças significativas, sendo que as embalagens comerciais tiveram tempos de resfriamento de 1,25 e 2 vezes maiores. Concluiu-se que a simulação estrutural computacional, aliada a algoritmos de otimização, além de procedimentos experimentais ligados à cadeia do frio, são recursos promissores no auxílio de projetos para embalagens de transporte de produtos hortícolas.
