Bellagio Report on Healthy Agriculture, Healthy Nutrition, Healthy People.

The Bellagio Report on Healthy Agriculture, Healthy Nutrition, Healthy People is the result of the meeting held at the Rockefeller Foundation Bellagio Center in Lake Como, Italy 30 October-1 November, 2012. The meeting was science-based but policy-oriented. The role and amount of healthy and unhealthy fats, with attention to the relative content of omega-3 and omega-6 fatty acids, sugar, and particularly fructose in foods that may underlie the epidemics of non-communicable diseases (NCDs) worldwide were extensively discussed. The report concludes that sugar consumption, especially in the form of high energy fructose in soft drinks, poses a major and insidious health threat, especially in children, and most diets, although with regional differences, are deficient in omega-3 fatty acids and too high in omega-6 fatty acids. Gene-nutrient interactions in growth and development and in disease prevention are fundamental to health, therefore regional Centers on Genetics, Nutrition and Fitness for Health should be established worldwide. Heads of state and government must elevate, as a matter of urgency, nutrition as a national priority, that access to a healthy diet should be considered a human right and that the lead responsibility for nutrition should be placed in Ministries of Health rather than agriculture so that the health requirements drive agricultural priorities, not vice versa. Nutritional security should be given the same priority as food security.

LDL cholesterol goals and cardiovascular risk during statin treatment: the IDEAL study.

AIMS: We assessed the proportion of patients treated with either simvastatin 20 or 40 mg or atorvastatin 80 mg who achieved low-density lipoprotein cholesterol (LDL-C) goals of 2.5 or 2.0 mmol/l in the Incremental Decrease in End Points Through Aggressive Lipid Lowering (IDEAL) study. We explored how lipoprotein components related to cardiovascular disease (CVD) outcomes in these groups. METHODS AND RESULTS: For subjects who reached on-treatment LDL-C goals, Cox regression models were used to assess the ability of lipoprotein components to predict CVD events. Treatment with simvastatin or atorvastatin resulted in 40 per cent and 80 per cent of patients, respectively, reaching the 2.5 mmol/l goal and 12 per cent and 52 per cent, respectively, reaching the 2.0 mmol/l goal, after 1 year (all p < 0.001 between groups). Adjusting for baseline LDL-C levels, hazard ratio (HR) for those reaching 2.0-2.5 mmol/l LDL-C versus those reaching <2.0 mmol/l was 1.16 (95% confidence interval [CI], 1.02-1.33, p = 0.023). An increase of the apolipoprotein B/A1 (apoB/A1) ratio by 1 standard deviation in participants who reached 2.0 mmol/l showed a HR for CVD of 1.14 (95% CI, 1.04-1.25, p = 0.004). CONCLUSION: More CVD patients treated with atorvastatin than simvastatin achieved either LDL-C goal and those reaching the 2.0 mmol/l goal exhibited significantly less CVD than those only reaching 2.5 mmol/l. In those reaching the 2.0 mmol/l goal, the apoB/A1 ratio still bears a relation to CVD outcome. The use of apoB/A1 ratio may provide additional predictive value to that of LDL-C.

Adherence-adjusted efficacy with intensive versus standard statin therapy in patients with acute myocardial infarction in the IDEAL study.

BACKGROUND: The Incremental Decrease in End Points through Aggressive Lipid Lowering trial showed that the primary endpoint major coronary event was reduced by 11% (0.78-1.01) using atorvastatin 80 mg versus simvastatin 20-40 mg in patients with coronary heart disease (P=0.07). Adherence was high in both treatment groups but significantly higher in patients treated with simvastatin. DESIGN: The Incremental Decrease in End Points through Aggressive Lipid Lowering was a prescription trial with a prospective randomized open label endpoint evaluation. METHODS AND RESULTS: Adherence was calculated as exposure time on prescribed drugs divided by total follow-up time until death or end of follow-up and was a potential confounder. Adjusting for categorical adherence below or above 80% by two methods revealed that the relative risk reduction of the primary endpoint was more in the region of 15% (P=0.02) than 11% as found unadjusted. Censoring at the first occurrence of a cardiovascular event rather than at death increased this estimate to 17% (P=0.02). Noncardiovascular mortality was reduced on atorvastatin treatment by 21% (1-37%) after adjustment for adherence, whereas such reduction was not observed for cardiovascular mortality. CONCLUSION: This study found that the difference in adherence between treatment groups may have underestimated the true effect of the treatment differential. Usage of prospective randomized open label endpoint evaluation design should be carefully considered when well-known treatments are compared with rather new ones and especially in segments where patients could be more vulnerable, as in the elderly. Nonadherers in a clinical trial may be at especially high risk of fatal and nonfatal endpoints from various diseases and should be carefully monitored.

Efficacy and tolerability of rosuvastatin and atorvastatin when force-titrated in patients with primary hypercholesterolemia: results from the ECLIPSE study.

BACKGROUND: Patients at high risk of cardiovascular disease frequently fail to reach recommended low-density lipoprotein cholesterol (LDL-C) goals, partly because statin doses are not titrated to optimal effect. The ECLIPSE study was designed to compare the efficacy and safety of force-titrated treatment with rosuvastatin (10-40 mg) with that of atorvastatin (10-80 mg) in high-risk patients with hypercholesterolemia. METHODS: In this 24-week, open-label, randomized, multinational, parallel-group study, 1,036 patients were randomized to rosuvastatin (n = 522) or atorvastatin (n = 514). RESULTS: At all time points, a significantly greater percentage of patients on rosuvastatin treatment achieved the NCEP ATP III LDL-C goal of <100 mg/dl (2.5 mmol/l), the 2003 European LDL-C target of <2.5 or 3.0 mmol/l (100 or 115 mg/dl) and the LDL-C goal of <70 mg/dl (1.8 mmol/l), a goal suggested for very high-risk patients (p < 0.001 for all). Rosuvastatin also achieved significantly greater improvements in components of the atherogenic lipid profile versus atorvastatin. Both treatments were well tolerated. CONCLUSION: Rosuvastatin titrated across its recommended dose range provides a more favorable effect on lipoprotein variables than atorvastatin, enabling more high-risk patients to achieve recommended LDL-C goals.

Cardiac rehabilitation: health characteristics and socio-economic status among those who do not attend.

BACKGROUND: Cardiac rehabilitation (CR) is well documented, in randomised trials, to reduce mortality risk after myocardial infarction (MI). Selection of healthy patients for CR is a relatively unexplored problem. Our aims were to identify predictors of CR-attendance and to describe the prognosis as concerns mortality, re-admission and invasive treatment among CR-attendees as compared to CR-non-attendees. METHODS: From a cohort of 138 290 persons aged 30-69 years, we identified consecutive MI patients, between 1 April 2000 and 31 March 2002. There were 206 MI patients, who survived until admission, and among the 200 who survived 30 days, 145 (72.5%) attended a comprehensive CR programme. Data were obtained from patient charts and from Danish population registers, and as a result we had no non-participation for the study. RESULTS: The 2-year mortality proportions for patients surviving the first 30 days of admission were 2.8 and 21.8% among CR-attendees and CR-non-attendees, respectively (P < 0.0001). Among CR-non-attendees, there was a smaller fraction having an invasive treatment performed as compared with CR-attendees. By multiple logistic regression controlling for age and sex, CR-attendance was associated with chest pain, whereas CR-non-attendance was associated with low gross income, single living and inverted T-wave in the electrocardiogram. CONCLUSION: CR attendance rate was 72.5%. Non-attendees have a higher mortality risk, which in part may be attributed to selection of healthy patients. Non-attendees are older and more likely to have atypical symptoms at admission, a low socioeconomic status and to live alone. Special attention is needed to improve CR attendance among such patients.

Enhancing the fatty acid profile of milk through forage-based rations, with nutrition modeling of diet outcomes.

Consumer demand for milk and meat from grass-fed cattle is growing, driven mostly by perceived health benefits and concerns about animal welfare. In a U. S.-wide study of 1,163 milk samples collected over 3 years, we quantified the fatty acid profile in milk from cows fed a nearly 100% forage-based diet (grassmilk) and compared it to profiles from a similar nationwide study of milk from cows under conventional and organic management. We also explored how much the observed differences might help reverse the large changes in fatty acid intakes that have occurred in the United States over the last century. Key features of the fatty acid profile of milk fat include its omega-6/omega-3 ratio (lower is desirable), and amounts of total omega-3, conjugated linoleic acid, and long-chain omega-3 polyunsaturated fatty acids. For each, we find that grassmilk is markedly different than both organic and conventional milk. The omega-6/omega-3 ratios were, respectively, 0.95, 2.28, and 5.77 in grassmilk, organic, and conventional milk; total omega-3 levels were 0.049, 0.032, and 0.020 g/100 g milk; total conjugated linoleic acid levels were 0.043, 0.023, and 0.019 g/100 g milk; and eicosapentaenoic acid levels were 0.0036, 0.0033, and 0.0025 g/100 g milk. Because of often high per-capita dairy consumption relative to most other sources of omega-3 fatty acids and conjugated linoleic acid, these differences in grassmilk can help restore a historical balance of fatty acids and potentially reduce the risk of cardiovascular and other metabolic diseases. Although oily fish have superior concentrations of long-chain omega-3 fatty acids, most fish have low levels of α-linolenic acid (the major omega-3), and an omega-6/omega-3 ratio near 7. Moreover, fish is not consumed regularly, or at all, by ~70% of the U. S.

From vulnerable plaque to vulnerable patient--Part III: Executive summary of the Screening for Heart Attack Prevention and Education (SHAPE) Task Force report.

Screening for early-stage asymptomatic cancers (eg, cancers of breast and colon) to prevent late-stage malignancies has been widely accepted. However, although atherosclerotic cardiovascular disease (eg, heart attack and stroke) accounts for more death and disability than all cancers combined, there are no national screening guidelines for asymptomatic (subclinical) atherosclerosis, and there is no government- or healthcare-sponsored reimbursement for atherosclerosis screening. Part I and Part II of this consensus statement elaborated on new discoveries in the field of atherosclerosis that led to the concept of the "vulnerable patient." These landmark discoveries, along with new diagnostic and therapeutic options, have set the stage for the next step: translation of this knowledge into a new practice of preventive cardiology. The identification and treatment of the vulnerable patient are the focuses of this consensus statement. In this report, the Screening for Heart Attack Prevention and Education (SHAPE) Task Force presents a new practice guideline for cardiovascular screening in the asymptomatic at-risk population. In summary, the SHAPE Guideline calls for noninvasive screening of all asymptomatic men 45-75 years of age and asymptomatic women 55-75 years of age (except those defined as very low risk) to detect and treat those with subclinical atherosclerosis. A variety of screening tests are available, and the cost-effectiveness of their use in a comprehensive strategy must be validated. Some of these screening tests, such as measurement of coronary artery calcification by computed tomography scanning and carotid artery intima-media thickness and plaque by ultrasonography, have been available longer than others and are capable of providing direct evidence for the presence and extent of atherosclerosis. Both of these imaging methods provide prognostic information of proven value regarding the future risk of heart attack and stroke. Careful and responsible implementation of these tests as part of a comprehensive risk assessment and reduction approach is warranted and outlined by this report. Other tests for the detection of atherosclerosis and abnormal arterial structure and function, such as magnetic resonance imaging of the great arteries, studies of small and large artery stiffness, and assessment of systemic endothelial dysfunction, are emerging and must be further validated. The screening results (severity of subclinical arterial disease) combined with risk factor assessment are used for risk stratification to identify the vulnerable patient and initiate appropriate therapy. The higher the risk, the more vulnerable an individual is to a near-term adverse event. Because <10% of the population who test positive for atherosclerosis will experience a near-term event, additional risk stratification based on reliable markers of disease activity is needed and is expected to further focus the search for the vulnerable patient in the future. All individuals with asymptomatic atherosclerosis should be counseled and treated to prevent progression to overt clinical disease. The aggressiveness of the treatment should be proportional to the level of risk. Individuals with no evidence of subclinical disease may be reassured of the low risk of a future near-term event, yet encouraged to adhere to a healthy lifestyle and maintain appropriate risk factor levels. Early heart attack care education is urged for all individuals with a positive test for atherosclerosis. The SHAPE Task Force reinforces existing guidelines for the screening and treatment of risk factors in younger populations. Cardiovascular healthcare professionals and policymakers are urged to adopt the SHAPE proposal and its attendant cost-effectiveness as a new strategy to contain the epidemic of atherosclerotic cardiovascular disease and the rising cost of therapies associated with this epidemic.

Genomic characterization of five deletions in the LDL receptor gene in Danish Familial Hypercholesterolemic subjects.

BACKGROUND: Familial Hypercholesterolemia is a common autosomal dominantly inherited disease that is most frequently caused by mutations in the gene encoding the receptor for low density lipoproteins (LDLR). Deletions and other major structural rearrangements of the LDLR gene account for approximately 5% of the mutations in many populations. METHODS: Five genomic deletions in the LDLR gene were characterized by amplification of mutated alleles and sequencing to identify genomic breakpoints. A diagnostic assay based on duplex PCR for the exon 7-8 deletion was developed to discriminate between heterozygotes and normals, and bioinformatic analyses were used to identify interspersed repeats flanking the deletions. RESULTS: In one case 15 bp had been inserted at the site of the deleted DNA, and, in all five cases, Alu elements flanked the sites where deletions had occurred. An assay developed to discriminate the wildtype and the deletion allele in a simple duplex PCR detected three FH patients as heterozygotes, and two individuals with normal lipid values were detected as normal homozygotes. CONCLUSION: The identification of the breakpoints should make it possible to develop specific tests for these mutations, and the data provide further evidence for the role of Alu repeats in intragenic deletions.

Mortality and incidence of cancer during 10-year follow-up of the Scandinavian Simvastatin Survival Study (4S).

BACKGROUND: The effects of cholesterol-lowering treatment with statins on mortality and risk of cancer beyond the usual 5-6-year trial periods are unknown. We extended post-trial follow-up of participants in the Scandinavian Simvastatin Survival Study (4S) to investigate cause-specific mortality and incidence of cancer 5 years after closure of the trial. METHODS: 4S was a randomised double-blind trial of simvastatin or placebo in patients with coronary heart disease, serum total cholesterol 5.5-8.0 mmol/L, and serum triglycerides 2.5 mmol/L or lower. The double-blind period lasted for a median of 5.4 years (range for survivors 4.9-6.3) and ended in 1994. After the trial, most patients in both groups received open-label lipid-lowering treatment. National registers were used to assess mortality and causes of death and cancer incidence in the original treatment groups for a median total follow-up time of 10.4 years (range for survivors 9.9-11.3). Analysis was by intention to treat. FINDINGS: 414 patients originally allocated simvastatin and 468 assigned placebo died during the 10.4-year follow-up (relative risk 0.85 [95% CI 0.74-0.97], p=0.02), a difference largely attributable to lower coronary mortality in the simvastatin group (238 vs 300 deaths; 0.76 [0.64-0.90], p=0.0018). 85 cancer deaths arose in the simvastatin group versus 100 in the placebo group (0.81 [0.60-1.08], p=0.14), and 227 incident cancers were reported in the simvastin group versus 248 in the placebo group (0.88 [0.73-1.05], p=0.15). Incidence of any specific type of cancer did not rise in the simvastatin group. INTERPRETATION: Simvastatin treatment for 5 years in a placebo-controlled trial, followed by open-label statin therapy, was associated with survival benefit over 10 years of follow-up compared with open-label statin therapy for the past 5 years only. No difference was noted in mortality from and incidence of cancer between the original simvastatin group and placebo group.

The relationship of molecular genetic to clinical diagnosis of familial hypercholesterolemia in a Danish population.

The genes encoding the LDL receptor and apoB were screened for mutations associated with familial hypercholesterolemia (FH) in 408 patients referred to the Lipid Clinic in 1995-2003. The study aimed at testing the ability of three different sets of clinical criteria to predict the results of molecular genetic analysis, and secondly test whether population-based age- and sex-specific percentiles of LDL-cholesterol offer useful supplemental information in the selection of patients for molecular genetic analysis. The patients were retrospectively categorised according to Simon Broome Register Group criteria, Make Early Diagnosis to Prevent Early Death criteria (MEDPED) and the Dutch Lipid Clinic Network criteria, and the distribution of patients was compared to the results of the molecular genetic analysis. The study illustrates a classical dilemma. Mutation detection rates (and specificities) are high only if sensitivity is very low and vice versa: to find most mutation carriers, even patients with only possible FH must be examined by molecular genetic testing leading to mutation detection rates as low as 30-40%.

Detection of large deletions in the LDL receptor gene with quantitative PCR methods.

BACKGROUND: Familial Hypercholesterolemia (FH) is a common genetic disease and at the molecular level most often due to mutations in the LDL receptor gene. In genetically heterogeneous populations, major structural rearrangements account for about 5% of patients with LDL receptor gene mutations. METHODS: In this study we tested the ability of two different quantitative PCR methods, i.e. Real-Time PCR and Multiplex Ligation-Dependent Probe Amplification (MLPA), to detect deletions in the LDL receptor gene. We also reassessed the contribution of major structural rearrangements to the mutational spectrum of the LDL receptor gene in Denmark. RESULTS: With both methods it was possible to discriminate between one and two copies of the LDL receptor gene exon 5, but the MLPA method was cheaper, and it was far more accurate and precise than Real-Time PCR. In five of 318 patients with an FH phenotype, MLPA analysis revealed five different deletions in the LDL receptor gene. CONCLUSION: The MLPA method was accurate, precise and at the same time effective in screening a large number of FH patients for large deletions in the LDL receptor gene.

Familial hypercholesterolemia in St-Petersburg: the known and novel mutations found in the low density lipoprotein receptor gene in Russia.

BACKGROUND: Familial hypercholesterolemia is a human monogenic disease caused by population-specific mutations in the low density lipoprotein (LDL) receptor gene. Despite thirteen different mutations of the LDL receptor gene were reported from Russia prior to 2003, the whole spectrum of disease-causing gene alterations in this country is poorly known and requires further investigation provided by the current study. METHODS: Forty-five patients with clinical diagnosis of FH were tested for the apolipoprotein B (apoB) mutation R3500Q by restriction fragment length analysis. After exclusion of R3500Q mutation high-sensitive fluorescent single-strand conformation polymorphism (SSCP) analysis and automatic DNA sequencing were used to search for mutations in the LDL receptor gene. RESULTS: We found twenty one rare sequence variations of the LDL receptor gene. Nineteen were probably pathogenic mutations, and two (P518P, T705I) were considered as neutral ones. Among the mutations likely to be pathogenic, eight were novel (c.670-671insG, C249X, c.936-940del5, c.1291-1331del41, W422X, c.1855-1856insA, D601N, C646S), and eleven (Q12X, IVS3+1G>A, c.651-653del3, E207X, c.925-931del7, C308Y, L380H, c.1302delG, IVS9+1G>A, V776M, V806I) have already been described in other populations. None of the patients had the R3500Q mutation in the apoB gene. CONCLUSIONS: Nineteen pathogenic mutations in the LDL receptor gene in 23 probands were identified. Two mutations c.925-931del7 and L380H are shared by St.-Petersburg population with neighbouring Finland and several other mutations with Norway, Sweden or Denmark, i.e. countries from the Baltic Sea region. Only four mutations (c.313+1G>A, c.651-653del3, C308Y and W422X) were recurrent as all those were found in two unrelated families. By this study the number of known mutations in the LDL receptor gene in St.-Petersburg area was increased nearly threefold. Analysis of all 34 low density lipoprotein receptor gene mutations found in St.-Petersburg argues against strong founder effect in Russian familial hypercholesterolemia.

High-dose atorvastatin vs usual-dose simvastatin for secondary prevention after myocardial infarction: the IDEAL study: a randomized controlled trial.

CONTEXT: Evidence suggests that more intensive lowering of low-density lipoprotein cholesterol (LDL-C) than is commonly applied clinically will provide further benefit in stable coronary artery disease. OBJECTIVE: To compare the effects of 2 strategies of lipid lowering on the risk of cardiovascular disease among patients with a previous myocardial infarction (MI). DESIGN, SETTING, AND PARTICIPANTS: The IDEAL study, a prospective, randomized, open-label, blinded end-point evaluation trial conducted at 190 ambulatory cardiology care and specialist practices in northern Europe between March 1999 and March 2005 with a median follow-up of 4.8 years, which enrolled 8888 patients aged 80 years or younger with a history of acute MI. INTERVENTIONS: Patients were randomly assigned to receive a high dose of atorvastatin (80 mg/d; n = 4439), or usual-dose simvastatin (20 mg/d; n = 4449). MAIN OUTCOME MEASURE: Occurrence of a major coronary event, defined as coronary death, confirmed nonfatal acute MI, or cardiac arrest with resuscitation. RESULTS: During treatment, mean LDL-C levels were 104 (SE, 0.3) mg/dL in the simvastatin group and 81 (SE, 0.3) mg/dL in the atorvastatin group. A major coronary event occurred in 463 simvastatin patients (10.4%) and in 411 atorvastatin patients (9.3%) (hazard ratio [HR], 0.89; 95% CI, 0.78-1.01; P = .07). Nonfatal acute MI occurred in 321 (7.2%) and 267 (6.0%) in the 2 groups (HR, 0.83; 95% CI, 0.71-0.98; P = .02), but no differences were seen in the 2 other components of the primary end point. Major cardiovascular events occurred in 608 and 533 in the 2 groups, respectively (HR, 0.87; 95% CI, 0.77-0.98; P = .02). Occurrence of any coronary event was reported in 1059 simvastatin and 898 atorvastatin patients (HR, 0.84; 95% CI, 0.76-0.91; P<.001). Noncardiovascular death occurred in 156 (3.5%) and 143 (3.2%) in the 2 groups (HR, 0.92; 95% CI, 0.73-1.15; P = .47). Death from any cause occurred in 374 (8.4%) in the simvastatin group and 366 (8.2%) in the atorvastatin group (HR, 0.98; 95% CI, 0.85-1.13; P = .81). Patients in the atorvastatin group had higher rates of drug discontinuation due to nonserious adverse events; transaminase elevation resulted in 43 (1.0%) vs 5 (0.1%) withdrawals (P<.001). Serious myopathy and rhabdomyolysis were rare in both groups. CONCLUSIONS: In this study of patients with previous MI, intensive lowering of LDL-C did not result in a significant reduction in the primary outcome of major coronary events, but did reduce the risk of other composite secondary end points and nonfatal acute MI. There were no differences in cardiovascular or all-cause mortality. Patients with MI may benefit from intensive lowering of LDL-C without an increase in noncardiovascular mortality or other serious adverse reactions.Trial Registration ClinicalTrials.gov Identifier: NCT00159835.

Nutrition, food production and health - an agenda also for cardiologists.

The relationship of cardiovascular disease to food has become more complicated on a scientific level yet starkly simpler on the level of policies for producing food for planetary as well as human health. Accordingly, we argue that professional societies in medicine should take a broader view of the scientific methods necessary to understand the complex issues of nutrition and cardiovascular and other disease, and they should lend greater support to policies for agriculture and the food industry that protect ecosystems, combat climate change and promote cardiovascular health.

No genetic linkage or molecular evidence for involvement of the PCSK9, ARH or CYP7A1 genes in the Familial Hypercholesterolemia phenotype in a sample of Danish families without pathogenic mutations in the LDL receptor and apoB genes.

A locus on chromosome 1p34.1-p32 has been linked to autosomal dominant Familial Hypercholesterolemia (FH) and is termed the third FH locus. We tested whether this third FH locus is linked to the FH phenotype in 20 Danish families, with 158 members, without pathogenic mutations in the genes, encoding the low-density lipoprotein (LDL) receptor or apolipoprotein B (apoB). We could exclude the third FH locus as a cause of FH by genetic linkage analysis in the families taken together. Since haplotype analysis of each family nevertheless suggested that the FH phenotype co-segregated in a manner consistent with linkage to the third FH locus in three small pedigrees, we performed sequencing analysis without being able to demonstrate mutations in the proprotein convertase subtilisin/kexin type 9 (PCSK9) gene, the main candidate gene in the third FH locus. By the same combination of genetic linkage and molecular analysis we could also exclude mutations in the gene for the LDL receptor adaptor protein and in the gene for cholesterol-7-alpha-hydroxylase as causes of FH in our sample. Although not indicating linkage to any known loci, our data still indicate that another dominant gene may be involved in causing a FH phenotype.

Design and baseline characteristics of the Incremental Decrease in End Points through Aggressive Lipid Lowering study.

The Incremental Decrease in End Points through Aggressive Lipid Lowering (IDEAL) study is an investigator-initiated trial designed to determine whether additional clinical benefit might be gained through a strategy that decreases levels of low-density lipoprotein cholesterol levels better than those currently achieved with established statin therapy in patients who have coronary heart disease. IDEAL is a multicenter prospective, randomized, open-label, blinded, end point classification study. Patients who had myocardial infarction were randomized to prescription treatment with 80 mg/day of atorvastatin or 20 mg/day of simvastatin (the dose was increased to 40 mg/day at week 24 in those patients whose plasma total cholesterol remained >5.0 mmol/L, or 190 mg/dl, or whose low-density lipoprotein cholesterol remained >3.0 mmol/L, or 115 mg/dl). The primary clinical outcome variable is the time to initial occurrence of a major coronary event, which is defined as nonfatal acute myocardial infarction, coronary death, or resuscitated cardiac arrest. The study is designed to have a power of 90% to detect a relative decrease of 20% in the atorvastatin-group compared with the simvastatin-group in the number of major events caused by coronary heart disease over approximately 5.5 years. The 8,888 randomized patients had the following characteristics: mean age 61.7 +/- 9.5 years, 19.1% women (mean age 64.0 +/- 9.5 years), baseline total cholesterol 5.1 +/- 1.0 mmol/L (197 mg/dl), low-density lipoprotein cholesterol 3.2 +/- 0.9 mmol/L (124 mg/dl), and high-density lipoprotein cholesterol 1.2 +/- 0.3 mmol/L (46 mg/dl). Drug treatment before randomization consisted of statins in 77% of patients, aspirin in 78.9%, beta blockers in 75.1%, and angiotensin-converting enzyme inhibitors in 30%.

Bellagio report on healthy agriculture, healthy nutrition, healthy people.

The Bellagio Report on Healthy Agriculture, Healthy Nutrition, Healthy People is the result of the meeting held at the Rockefeller Foundation Bellagio Center in Lake Como, Italy, 29 October-2 November 2012. The meeting was science-based but policy-oriented. The role and amount of healthy and unhealthy fats, with attention to the relative content of omega-3 and omega-6 fatty acids, sugar, and particularly fructose in foods that may underlie the epidemics of non-communicable diseases (NCD's) worldwide were extensively discussed. The report concludes that sugar consumption, especially in the form of high energy fructose in soft drinks, poses a major and insidious health threat, especially in children, and most diets, although with regional differences, are deficient in omega-3 fatty acids and too high in omega-6 fatty acids. Gene-nutrient interactions in growth and development and in disease prevention are fundamental to health, therefore regional Centers on Genetics, Nutrition and Fitness for Health should be established worldwide. Heads of state and government must elevate, as a matter of urgency, Nutrition as a national priority, that access to a healthy diet should be considered a human right and that the lead responsibility for Nutrition should be placed in Ministries of Health rather than agriculture so that the health requirements drive agricultural priorities, not vice versa. Nutritional security should be given the same priority as food security.

El informe del Bellagio sobre Agricultura Saludable, Nutrición Saludable, Población Saludable es el resultado de la reunión mantenida en el Centro Bellagio de la Fundación Rockefeller en el Lago de Como en Italia, entre el 29 de Octubre y el 2 de Noviembre de 2012. La reunión basada en la ciencia, fue orientada hacia la política. Se discutió extensamente el papel y la cantidad de grasas saludables y perjudiciales, con atención al contenido relativo de los ácidos grasos omega-3 y omega-6, el azúcar, y particularmente la fructosa en los alimentos que pueden conllevar la epidemia de enfermedades no transmisibles (EnT) a través del mundo. El informe concluye que el consumo del azúcar, especialmente en forma de fructosa de alta energía utiizada en bebidas refrescantes, posee una amenaza muy importante de la salud, especialmente en niños, y la mayoría de las dietas, aunque con diferencias regionales, son deficientes en ácidos grasos omega-3 y demasiado altas en ácidos grasos omega-6. Las interacciones gen-nutriente en el crecimiento y desarrollo y en la prevención de la enfermedad son fundamentales para la salud, por lo que deberían establecerse a través de todo el mundo Centros regionales de Genética, Nutrición y Condición Física para la Salud. Los jefes de estado y gobierno deben priorizar dentro de sus nacionales de forma urgente la Nutrición, cuyo acceso a una dieta saludable debería considerarse un derecho humano y dirigir la responsabilidad para que la Nutrición tenga un lugar en los Ministerios de Salud, más que la agricultura de modo que los requerimientos de salud conduzcan a prioridades agrícolas, y no viceversa. La seguridad nutricional debería ser considerada como prioridad como lo es la seguridad alimentaria.

Effect of intensive lipid lowering with atorvastatin on cardiovascular outcomes in coronary heart disease patients with mild-to-moderate baseline elevations in alanine aminotransferase levels.

BACKGROUND: Statins may reduce cardiovascular (CV) morbidity in patients with mild-to-moderate elevations in liver enzyme levels. This post-hoc analysis of the IDEAL study compared intensive versus moderate statin therapy for the prevention of CV events in coronary heart disease patients with normal and elevated baseline levels of serum alanine aminotransferase (ALT). METHODS: Cox regression analysis was used to investigate the effect of atorvastatin 80 mg/day versus simvastatin 20-40 mg/day on the risk of IDEAL study end points in patients with normal baseline ALT (defined as ALT < ULN [upper limit of normal]) versus elevated baseline ALT (ALT ≥ ULN). RESULTS: Of 8863 IDEAL patients with non-missing baseline ALT values, 7782 (87.8%) had an ALT < ULN and 1081 (12.2%) had an ALT ≥ ULN. In patients with elevated baseline ALT, major CV event rates were 11.5% for simvastatin and 6.5% for atorvastatin, indicating a significant risk reduction with intensive statin therapy (hazard ratio, 0.556; 95% confidence interval, 0.367-0.842; p = 0.0056). Significant heterogeneity of treatment effect was observed for major CV events, cerebrovascular events, and major coronary events, with a trend towards treatment difference for the other outcomes, indicating a greater benefit with atorvastatin in the elevated ALT group. CONCLUSIONS: The CV benefit of intensive lipid lowering with atorvastatin compared with a more moderate regimen with simvastatin was generally greater in patients with mildly-to-moderately elevated baseline ALT than patients with normal baseline ALT. Moderate elevations in liver enzyme levels should not present a barrier to prescribing statins, even at higher doses, in high-risk patients.
