Comment diminuer son risque cardiovasculaire avec l'alimentation? Rôle des graisses consommées [Nutritional advice to help reduce the cardiovascular risk. Update of the Swiss Federal Office of Public Health's recommendations on fat consumption].

The Swiss Federal Office of Public Health's (FOPH) updated its recommendations on fat consumption in 2013. The report recommends that maximum 10% of the daily caloric intake should come from saturated fatty acids, and the total fat intake should account for 20-35%. There is no limitation to dietary cholesterol consumption. Recent studies have shown that replacing consumption of saturated fatty acids by unsaturated fatty acids is more beneficial in terms of cardiovascular prevention than a low fat diet. The purpose of this article is to review the FOPH recommendations on dietary fat as well as the current evidence about their cardiovascular benefit, and to provide a translation of these scientific recommendations into clinical advice.

Alcohol drinking and cardiovascular risk in a population with high mean alcohol consumption

Résumé : Description : Ce travail de thèse évalue l'impact de la consommation importante d'alcool sur les facteurs de risque cardiovasculaire et l'estimation du risque cardiovasculaire à 10 ans (risque de développer une maladie coronarienne}, dans une population avec une consommation moyenne élevée d'alcool. La consommation modérée d'alcool a été liée à un risque plus faible de développer une maladie coronarienne. Cependant, les données concernant la consommation importante d'alcool et le risque de développer une maladie coronarienne sont conflictuelles. Il y a également peu d'études dans lesquelles les consommations importantes d'alcool ont pu être évaluées en raison du petit nombre de sujets présentant une telle consommation. Résultats: Nous avons utilisé les données de l'étude CoLaus, une étude populationnelle qui inclut des adultes, âgés de 35 à 75 ans, de la ville de Lausanne. Nous avons inclus 5'769 participants, sans maladie cardiovasculaire, pour lesquels la consommation d'alcool d'une semaine a été catégorisée en 0, 1 à 6, 7 à 13, 14 à 20, 21 à 27, 28 à 34 et >=35 verres/semaine et en non-consommateur (0 verre/semaine), consommateur modéré (1 à 13 verres/semaine), important (14 à 34 verres/semaine) et très important (>= 35). La tension artérielle et les lipides ont été mesurés et le risque de développer une maladie coronarienne à 10 ans a été calculé en utilisant le score de Framingham. 73% des participants consommaient de l'alcool; 16% étaient des consommateurs importants et 2% des consommateurs très importants. L'analyse rnultivariée a montré une augmentation du cholestérol HDL avec la consommation d'alcool (de 1.570.01 [moyenne +- erreur standard] chez les non consommateurs à 1.880.03 mmol/L chez les consommateurs très importants), des triglycérides (1.17+-1.01 à 1.32+-1.05 mmol/L) et des valeurs de tension artérielle systolique (127.4+-0.4 à 132.2+-.4 mm Hg) et diastolique (78.7+-0.3 à 81.7+-0.9 mm Hg, toutes les valeurs de p pour trend<0.001). Quant au risque de développer une maladie coronarienne à 10 ans, il a augmenté de 4.31%+-0.10 à 4.90%+-0.37 (p=0.03) avec la consommation d'alcool, en décrivant une courbe en J. En examinant le type de consommation, on a vu que la consommation de vin a plus d'effet sur l'augmentation des valeurs de cholestérol HDL, alors que la consommation de bière ou de spiritueux a plus d'effet sur l'augmentation des valeurs de triglycérides. Conclusions et perspectives: Nos résultats montrent qu'en ce qui concerne l'estimation du risque cardiovasculaire à 10 ans, l'effet protecteur de la consommation d'alcool disparaît pour des consommations très importantes, car l'effet bénéfique des valeurs augmentées de cholestérol HDL est contrecarré par l'augmentation des valeurs de tension artérielle. Quant aux différents types d'alcool, d'autres études sont nécessaires pour mieux évaluer leur effet spécifique sur les facteurs de risque cardiovasculaire.

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.

Profile, cost and pattern of prescriptions for polymedicated patients in Catalonia (Spain).

OBJECTIVES: Polypharmacy is one of the main management issues in public health policies because of its financial impact and the increasing number of people involved. The polymedicated population according to their demographic and therapeutic profile and the cost for the public healthcare system were characterised. DESIGN: Cross-sectional study. SETTING: Primary healthcare in Barcelona Health Region, Catalonia, Spain (5 105 551 inhabitants registered). PARTICIPANTS: All insured polymedicated patients. Polymedicated patients were those with a consumption of ≥16 drugs/month. MAIN OUTCOMES MEASURES: The study variables were related to age, gender and medication intake obtained from the 2008 census and records of prescriptions dispensed in pharmacies and charged to the public health system. RESULTS: There were 36 880 polymedicated patients (women: 64.2%; average age: 74.5±10.9 years). The total number of prescriptions billed in 2008 was 2 266 830 (2 272 920 total package units). The most polymedicated group (up to 40% of the total prescriptions) was patients between 75 and 84 years old. The average number of prescriptions billed monthly per patient was 32±2, with an average cost of 452.7±27.5. The total cost of those prescriptions corresponded to 2% of the drug expenditure in Catalonia. The groups N, C, A, R and M represented 71.4% of the total number of drug package units dispensed to polymedicated patients. Great variability was found between the medication profiles of men and women, and between age groups; greater discrepancies were found in paediatric patients (5-14 years) and the elderly (≥65 years). CONCLUSIONS: This study provides essential information to take steps towards rational drug use and a structured approach in the polymedicated population in primary healthcare.

A global view of cross-border migration

This paper evaluates the global welfare impact of observed levels of migration using a quantitativemulti-sector model of the world economy calibrated to aggregate and firm-level data.Our framework features cross-country labor productivity differences, international trade, remittances,and a heterogeneous workforce. We compare welfare under the observed levels ofmigration to a no-migration counterfactual. In the long run, natives in countries that receiveda lot of migration -such as Canada or Australia- are better o due to greater product varietyavailable in consumption and as intermediate inputs. In the short run the impact of migrationon average welfare in these countries is close to zero, while the skilled and unskilled nativestend to experience welfare changes of opposite signs. The remaining natives in countries withlarge emigration flows -such as Jamaica or El Salvador- are also better off due to migration,but for a different reason: remittances. The welfare impact of observed levels of migration issubstantial, at about 5 to 10% for the main receiving countries and about 10% in countries withlarge incoming remittances. Our results are robust to accounting for imperfect transferabilityof skills, selection into migration, and imperfect substitution between natives and immigrants.

O2 consumption by the fick method. Methodologic factors.

This study aimed to compare O2 consumption (VO2) determination by the gas-exchange (VO2GE) and Fick (VO2F) methods in cardiac surgical patients. A total of 10 mechanically ventilated postoperative patients were studied prospectively. Thermodilution was performed using three randomly applied techniques: room temperature saline injected at end expiration, room temperature saline randomly injected in the respiratory cycle, and iced saline injected at end expiration. The influence of the number of thermodilution determinations was assessed by comparing results from 2 and 10 injections. The variability of VO2F was greater than that of VO2GE. There was no bias between VO2GE and VO2F values using injectate at room temperature. Accuracy and precision were not improved by increasing the number of cardiac output determinations from 2 to 10. A significant bias was observed using ice-cold injectate, VO2F being 18.0 +/- 15.4 ml/min/m2 lower than VO2GE (p = 0.001). Published results when comparing VO2F and VO2GE are discrepant. However, a significant bias was found in all studies using cold injectate, with lower VO2F values. We conclude that iced injectate should not be used to assess VO2 in critically ill patients.

Association entre consommation d'alcool et facteurs de risque cardiovasculaire: une étude sur la population lausannoise. [Association between alcohol consumption and cardiovascular risk factors: a narrative review]

Alors que la consommation modérée d'alcool est liée à un risque plus faible de développer une maladie coronarienne, l'impact d'une consommation plus importante d'alcool sur les facteurs de risque cardiovasculaire (FRCV) et la maladie coronarienne est moins clair. Nous avons étudié l'association entre la consommation d'alcool, les FRCV et l'estimation du risque à dix ans de faire un événement cardiovasculaire dans l'étude populationnelle lausannoise CoLaus. Dans cette étude, 73% des participants consomment de l'alcool, 16% consomment de 14 à 34 unités d'alcool par semaine et 2% consomment 35 unités ou plus par semaine. Cet article montre notamment l'impact d'une consommation importante d'alcool sur les FRCVet passe en revue les liens entre la consommation d'alcool, le type de boissons et les FRCV. [Abstract] Moderate alcohol consumption has been associated with lower coronary heart disease (CHD) risk. However, the impact of higher alcohol consumption on cardiovascular risk factors (CVRFs) is conflicting. We examined the association between alcohol consumption, CVRFs and the estimated 10-year CHD risk in the population-based CoLaus study in Lausanne, Switzerland. Among 5'769 participants without cardiovascular disease, 73% of the participants were alcohol drinkers; 16% consumed 14-34 drinks/week and 2% consumed >= 35 drinks/week. This article shows the impact of high alcohol consumption on CVRFs and reviews the literature on the associations between alcohol consumption and CVRFs.

Hemispheric language asymmetry in first episode psychosis and schizotypy : the role of cannabis consumption and cognitive disorganization

Cannabis use has been related to an elevated psychosis risk and attenuated cognitive functioning. Cannabis-related cognitive impairments are also observed in populations along the psychosis dimension. We here investigated whether a potential behavioural marker of the psychosis dimension (attenuated functional hemispheric asymmetry) is even further attenuated in individuals using cannabis (CU) versus those not using cannabis (nCU). We tested 29 patients with first episode psychosis (FEP; 11 CU) and 90 healthy controls (38 CU) on lateralized lexical decisions assessing left hemisphere language dominance. In patients, psychotic symptoms were assessed (PANSS). In controls, self-reported schizotypy was assessed (O-LIFE questionnaire). Results indicated that nCU FEP patients had a relative reduced hemispheric asymmetry, as did controls with increasing cognitive disorganisation scores, in particular when belonging to the group of nCU controls. Positive, disorganised and negative PANSS scores in patients and negative and positive schizotypy in controls were unrelated to hemispheric asymmetry. These findings suggest that cannabis use balances rather than exacerbates uncommon hemispheric laterality patterns. Moreover, in healthy populations, the potential stabilisation of typical hemispheric asymmetry in CU might be most relevant to individuals with elevated cognitive disorganisation. We discuss the potential beneficial and harmful effects of cannabis use along the psychosis dimension together with propositions for future studies that should account for the mediating role of additional substances (e.g. nicotine), cannabis composition (e.g. cannabidiol content), and individual differences (e.g. physical health, or absence of significant polysubstance use).
