ARE FRUIT AND VEGETABLE STAMP POLICIES COST-EFFECTIVE?

In many countries, consumption of fruits and vegetables (F&V) is below recommended levels. We quantify the economic and health effects of F&V stamp policy designed for low income consumers. The analysis combined two models: an economic model which predicts how F&V consumption is affected by a change in policy and a health model which evaluates the impact of a change in F&V consumption in terms of death avoided (DA) and life-years saved (LYS). Finally we computed the costs per DA and LYS as the ratio between the taxpayer cost of the policy and the number of DA and LYS. The main findings of the present study are: (1) F&V stamp policy has a positive and significant impact on the consumption of small F&V consumers of the targeted population, (2) at the aggregate level, this policy has a modest impact on consumption and as a result on health gains, (3) for a given budget allocated to the policy, the cost per DA or LYS decreases when the targeting is smaller, at least as long as consumption remains in plausible values, (4) the policy reduces the health inequalities between low and high income populations, (5) when well designed, F&V stamp policy is as cost-effective as price policy (about 42 k€/LYS).Cost-effectiveness analysis, Fruits and Vegetables, Health Impact Assessment, Health Policy, Agricultural and Food Policy, Consumer/Household Economics, Demand and Price Analysis, Food Consumption/Nutrition/Food Safety, Food Security and Poverty, Health Economics and Policy, D61, I18, Q18,

Gender differences in the implementation of cardiovascular prevention measures after an acute coronary event

Objective To compare gender-related lifestyle changes and risk factor management after hospitalisation for a coronary event or revascularisation intervention in Europe. Method The EUROASPIRE III survey was carried out in 22 European countries in 2006-2007. Consecutive patients having had a coronary event or revascularisation before the age of 80 were identified. A total of 8966 patients (25.3% women) were interviewed and underwent clinical and biochemical tests at least 6 months after hospital admission. Trends in cardiovascular risk management were assessed on the basis of the 1994-1995, 1999-2000 and 2006-2007 EUROASPIRE surveys. Results Female survey participants were generally older and had a lower educational level than male participants (p<0.0001). The prevalences of obesity (p<0.0001), high blood pressure (BP) (p=0.001), elevated low-density lipoprotein (LDL)-cholesterol (p<0.0001) and diabetes (p<0.0001) were significantly higher in women than in men, whereas current smoking (p<0.0001) was significantly more common in men. The use of antihypertensive and antidiabetic drugs (but not that of other drugs) was more common in women than in men. However, BP (p<0.0001), LDL-cholesterol (p<0.0001) and HbA1c (p<0.0001) targets were less often achieved in women than in men. Between 1994 and 2007, cholesterol control improved less in women than in men (interaction: p=0.009), whereas trends in BP control (p=0.32) and glycaemia (p=0.36) were similar for both genders. Conclusion The EUROASPIRE III results show that despite similarities in medication exposure, women are less likely than men to achieve BP, LDL-cholesterol and HbA1c targets after a coronary event. This gap did not appear to narrow between 1994 and 2007

Adrenocorticotrophic hormone lowers serum Lp(a) and LDL cholesterol concentrations in hemodialysis patients

Adrenocorticotrophic hormone lowers serum Lp(a) and LDL cholesterol concentrations in hemodialysis patients. Previously, we have shown that short-term administration of adrenocorticotrophic hormone (ACTH) results in reduced concentrations of apolipoprotein B-containing lipoproteins, including lipoprotein(a), and reduced activities of hepatic lipase. These effects were observed in steroid-treated patients suffering from iatrogenic ACTH deficiency and in healthy individuals. The direct nature of the influence of ACTH on hepatic lipoprotein metabolism was confirmed by in vitro experiments. The aim of the present investigation was to study the effects of ACTH treatment on uremic patients, who exhibit disturbed lipoprotein pattern due to the slow removal of triglyceride-rich lipoproteins and who probably are ACTH resistant. Eight patients on chronic hemodialysis were studied. After one intramuscular injection of Synacthen Depot (a synthetic ACTH1–24 preparation from Ciba Geigy AG, Basel, Switzerland) 1 mg, the only change noted was a significant reduction of 26% in median lipoprotein(a) concentration. After five injections, a further decrease (65%) was found in the lipoprotein(a) concentration. Also, reductions in median concentrations of total cholesterol, low density lipoprotein cholesterol and apolipoprotein B were observed. The magnitude of these changes was 15 to 30%. In contrast to previously studied groups, no changes were observed regarding triglyceride metabolism. Significantly increased median concentration of apolipoprotein CIII was found. However, the excess apolipoprotein CIII was confined to the fraction that was not associated with apolipoprotein B. Thus, administration of ACTH to uremic patients improved their atherogenic lipoprotein profile, a fact that may have future therapeutic implications. In comparison to previously studied groups, the uremic patients responded rather slowly and not at all regarding triglyceride metabolism

Observational study of adherence to European clinical practice guidelines for the management of acute coronary syndrome in revascularized versus non-revascularized patients – the CONNECT Study

SummaryBackgroundThe CONNECT study compared clinician adherence to guideline-recommended secondary prevention therapies prescribed at discharge for patients hospitalized for acute coronary syndrome (ACS) in those managed initially with percutaneous coronary intervention (PCI; revascularized) and those who did not undergo revascularization.MethodsPatients aged greater than or equal to 18 years, hospitalized for a documented ST-segment elevation or non-ST-segment elevation ACS, were enrolled consecutively over 1 month at 238 sites in France.ResultsCompared with revascularized patients (n=870), non-revascularized patients (n=706) were significantly older, and a greater proportion were women, had high-blood pressure, type-2 diabetes or a history of atherothrombotic or cardiac disease, but a smaller proportion had a history of coronary angioplasty. On discharge, non-revascularized patients were prescribed beta-blockers, aspirin, statins, angiotensin-converting enzyme inhibitors or adenosine diphosphate receptor antagonists less frequently than revascularized patients. An adherence score greater than or equal to 80% (at least four of the five recommended agents prescribed at discharge) was found in 96.7% of revascularized patients and 74.4% of non-revascularized patients (P<0.001).ConclusionsDespite a similar or even higher level of cardiovascular risk, non-revascularized ACS patients were prescribed guideline-recommended secondary prevention therapy less frequently than revascularized patients

0098: Erythrocyte membrane phospholipid fatty acids, dairy intakes and cardiovascular risk

IntroductionThe impact of dairy fats on cardiovascular risk has been debated. Circulating Pentadecanoic (15:0) and heptadecanoic (17:0) saturated fatty acids are good biomarkers of dairy product consumption as they are mainly provided by dairy fats. We described the prevalence of cardiovascular risk factors according to erythrocyte membrane phospholipid content in 15:0 and 17:0 fatty acids.Methods402 women and men aged 45-64 were randomly selected in 2005-2007, from the general population of three French areas. Nutritional data were collected through a 3-day food record. Fatty acid content was measured in erythrocyte membrane phospholipids.ResultsErythrocyte membrane contents in 15:0 and 17:0 fatty acids significantly increased with the consumption of dairy products collected during the 3-day food record. Prevalence of hypertension significantly decreased from the lowest to the highest quartile of 15:0 erythrocyte content (48.1%; 33.3%; 29.9%; 25.5%; p=0.005). A similar trend was observed for metabolic syndrome prevalence (39.4%; 28.1%; 25.2%; 21.3%; p=0.029). Prevalence of hypertension, hypertriglyceridaemia, overweight and metabolic syndrome significantly decreased from the lowest to the highest quartile of 17:0 erythrocyte content (44.1%; 36.5%; 28.1%; 25.6%; p=0.020 for hypertension; 30.3%; 15.4%; 16.9%; 16.7%; p=0.017 for hypertriglyceridaemia; 68.1%; 58.7%; 46.6%; 44.4%; p=0.002 for overweight; and 43.2%; 26.9%; 22.5%; 17.8%; p<0.001 for metabolic syndrome). All these relationships remained significant after adjustment for age and gender. The link did not reach significance level for diabetes.ConclusionElevated erythrocyte membrane phospholipid contents in 15:0 and 17:0 saturated fatty acids are associated with a lower prevalence of the metabolic syndrome and several of its components. These results suggest that saturated fat intake should not be systematically associated with high cardiovascular risk and can be considered as part of a balanced diet

A common variant of endothelial nitric oxide synthase (Glu298Asp) is associated with collateral development in patients with chronic coronary occlusions

BACKGROUND: Experimental studies support an important role for endothelial nitric oxide synthase (eNOS) in the regulation of angiogenesis. In humans, a common polymorphism exists in the eNOS gene that results in the conversion of glutamate to aspartate for codon 298. In vitro and in vivo studies have suggested a decreased NOS activity in patients with the Asp(298 )variant. We hypothesized that a genetic-mediated decreased eNOS activity may limit collateral development in patients with chronic coronary occlusions. METHODS: We selected 291 consecutive patients who underwent coronary angiography and who had at least one chronic (>15 days) total coronary occlusion. Collateral development was graded angiographically using two different methods: the collateral flow grade and the recipient filling grade. Genomic DNA was extracted from white blood cells and genotyping was performed using previously published techniques. RESULTS: Collateral development was lower in patients carrying the Asp(298 )variant than in Glu-Glu homozygotes (collateral flow grade: 2.64 ± 0.08 and 2.89 ± 0.08, respectively, p = 0.04; recipient filling grade: 3.00 ± 0.08 and 3.24 ± 0.07, respectively, p = 0.04). By multivariable analysis, three variables were independently associated with the collateral flow grade: female gender, smoking, and the Asp(298 )variant (p = 0.03) while the Asp(298 )variant was the sole variable independently associated with the recipient filling grade (p = 0.03). CONCLUSION: Collateral development is lower in patients with the Asp(298 )variant. This may be explained by the decreased NOS activity in patients with the Asp(298 )variant. Further studies will have to determine whether increasing eNOS activity in humans is associated with coronary collateral development

The major element of 1-year prognosis in acute coronary syndromes is severity of initial clinical presentation: Results from the French MONICA registries

SummaryBackgroundWhile the death rate from acute coronary syndromes (ACS) has been in decline for more than 50years, out-of-hospital mortality remains high despite improvements in care.AimTo evaluate the importance of out-of-hospital mortality and identify the main predictors of in-hospital and 1-year mortality in France.MethodsAnalyses were based on data from the French MONICA population-based registry, which included all cases of ACS occurring in people aged 35–74years during 2006 in three geographic areas in France. We first evaluated out-of-hospital mortality; then, using data from patients with incident ACS who reached hospital alive, Cox models were performed to determine the main predictors of 1-year mortality. The number of attributable deaths was assessed for variables of interest.ResultsAfter 1-year follow-up, case-fatality was 29.3% for incident events (n=2547); the proportion of out-of-hospital deaths was 70.3%, and 91.5% of deaths occurred in the 28days following the ACS. On multivariable analysis, the number of attributable deaths associated with three scenarios (out-of-hospital life-and-death emergency, hospitalization before ACS occurrence, and lack of coronary angiography) was 130 (accounting for 59% of deaths occurring after reaching the hospital) during 1-year follow-up. These scenarios corresponded to patients with an initial severe clinical presentation in whom rates of use of specific treatments and invasive procedures were very low.ConclusionA large proportion of fatalities after an ACS occurs in the out-of-hospital phase. Moreover, the major component of 1-year mortality is associated with a poor prognosis at initial presentation. This finding highlights the importance of cardiovascular prevention, population education and better out-of-hospital emergency management in improving prognosis after an ACS

Frequency of fruit and vegetable consumption and coronary heart disease in France and Northern Ireland: the PRIME study

Fruit and vegetable consumption is associated with low CHD risk in the USA and Northern Europe. There is, in contrast, little information about these associations in other regions of Europe. The goal of the present study was to assess the relationship between frequency of fruit and vegetable intake and CHD risk in two European populations with contrasting cardiovascular incidence rates; France and Northern Ireland. The present prospective study was in men aged 50-59 years, free of CHD, who were recruited in France (n 5982) and Northern Ireland (n 2105). Fruit and vegetable intake was assessed by a food-frequency questionnaire. Incident cases of acute coronary events and angina were recorded over a 5-year follow-up. During follow-up there was a total of 249 ischaemic events. After adjustment on education level, smoking, physical activity, alcohol consumption, employment status, BMI, blood pressure, serum total and HDL-cholesterol, the relative risks (RR) of acute coronary events were 0·67 (95% CI 0·44, 1·03) and 0·64 (95% CI 0·41, 0·99) in the 2nd and 3rd tertiles of citrus fruit consumption, respectively (P for trend <0·03). Similar results were observed in France and Northern Ireland. In contrast, the RR of acute coronary events for ‘other fruit' consumption were 0·70 (95% CI 0·31, 1·56) and 0·52 (95% CI 0·24, 1·14) respectively in Northern Ireland (trend P<0·05) and 1·29 (95% CI 0·69, 2·4) and 1·15 (95% CI 0·68, 1·94) in France (trend P=0·5; interaction P<0·04). There was no evidence for any association between vegetable intake and total CHD events. In conclusion, frequency of citrus fruit, but not other fruits, intake is associated with lower rates of acute coronary events in both France and Northern Ireland, suggesting that geographical or related factors might affect the relationship between fruit consumption and CHD ris
