- BACKGROUND: Analyzing the impact of the intake of many foods simultaneously provides additional knowledge about analyses of nutrients and might make it easier to implement recommendations for the public. OBJECTIVE: The objective was to examine food patterns in a Swedish population and determine how they are related to metabolic risk factors for cardiovascular disease. DESIGN: The study is based on data from the INTERGENE population study of women and men aged 25-74 y in western Sweden. Dietary patterns were identified with cluster analysis of 93 food frequencies reported by 3452 participants. Associations with features of the metabolic syndrome, including blood lipids, blood pressure, and anthropometric measures, were analyzed. RESULTS: Five distinct food patterns were identified, of which one was interpreted as a "healthy" reference pattern. This healthy cluster was distinguished by more frequent consumption of high-fiber and low-fat foods and lower consumption of products rich in fat and sugar. The 4 other clusters differed significantly from the reference cluster with respect to prevalence of cardiovascular disease risk factors and the metabolic syndrome. For example, body mass index and waist-to-hip ratio were significantly higher in a cluster characterized by high consumption of energy-dense drinks and white bread and low consumption of fruit and vegetables (P < 0.0001 and P = 0.004, respectively). CONCLUSIONS: It is possible to distinguish food patterns that are related to obesity and obesity-related cardiovascular disease risk factors in contrast with a more healthy pattern conforming with current dietary guidelines. Thus, the results indicate no reason for questioning the current recommendations.

- The role of dairy fat in the aetiology of myocardial infarction (MI) is controversial. The aim of this study was to evaluate the association between intake of dairy fat and dairy products, and risk of a first acute MI. A total of 111 MI patients with a first acute MI and 107 population controls (men and women, age 45-75 years) were studied. Diet was assessed using a 180-item food frequency questionnaire. The MI cases had higher intake of total fat, but lower intake of saturated fat and dairy fat than the control persons. No effect of dairy fat or saturated fat on the odds ratio for MI was observed, however. A significant inverse trend in odds of MI for intake of cheese was observed, but the trend was no longer significant after adjustment for smoking. The results suggest that intake of fat from dairy products may not be associated with increased risk of having a first MI. The healthy control persons had a diet that differed from the diet of the MI patients in many aspects, and dairy products were a part of this diet. This may have protected them from having a first MI.

- Although a number of environmental risk factors for atherosclerosis have been identified, heredity seems to be a significant independent risk factor. The aim of our study was to identify novel susceptibility genes for atherosclerosis. The screening process consisted of three steps. First, expression profiles of macrophages from subjects with atherosclerosis were compared to macrophages from control subjects. Secondly, the subjects were genotyped for promoter region polymorphisms in genes with altered gene expression. Thirdly, a population of subjects with coronary heart disease and control subjects were genotyped to test for an association with identified polymorphisms that affected gene expression. Twenty-seven genes were differentially expressed in both macrophages and foam cells from subjects with atherosclerosis. Three of these genes, IRS2, CD86 and SLC11A1 were selected for further analysis. Foam cells from subjects homozygous for the C allele at the -765C-->T SNP located in the promoter region of IRS2 had increased gene expression compared to foam cells from subjects with the nonCC genotype. Also, macrophages and foam cells from subjects homozygous for allele 2 at a repeat element in the promoter region of SLC11A1 had increased gene expression compared to macrophages and foam cells from subjects with the non22 genotype. Genotyping of 512 pairs of subjects with coronary heart disease (CHD) and matched controls revealed that subjects homozygous for C of the IRS2 SNP had an increased risk for CHD; odds ratio 1.43, p=0.010. Immunohistochemical staining of human carotid plaques showed that IRS2 expression was localised to macrophages and endothelial cells in vivo. Our method provides a reliable approach for identifying susceptibility genes for atherosclerosis, and we conclude that elevated IRS2 gene expression in macrophages may be associated with an increased risk of CHD.

- OBJECTIVE: Asymmetrical dimethylarginine (ADMA) reduces nitric oxide by inhibiting nitric oxide synthase is associated with cardiovascular disease (CVD). Our study examined the association of ADMA with CVD prospectively in a healthy population-based cohort of women. METHODS AND RESULTS: We measured baseline ADMA of 880 women in the Population Study of Women in Gothenburg using high-performance liquid chromatography. After adjustment for traditional risk factors, creatinine clearance, and homocysteine using Cox models, the HR (95% CI in parentheses) of CVD end points at 24 years for a 0.15 micromol/L (1 SD) increase in ADMA were: all-cause mortality 1.12 (0.96, 1.32), fatal CVD 1.30 (1.04, 1.62), total CVD events 1.29 (1.09, 1.53). The top quintile (ADMA >or=0.71 micromol/L) compared with the bottom four-fifths, conferred a cumulative risk 22 versus 14%, relative risk 1.75 (95% CI 1.18, 2.59) and population attributable risk 12.7% of total CVD events, and further identified individuals who are at higher than expected risk based on the SCORE and Framingham systems. CONCLUSIONS: A 0.15 mumol/L increase in baseline ADMA levels is associated with approximately 30% increase in incident cardiovascular risk at 24 years in women after adjustment. ADMA levels >or=0.71 micromol/L enhances CVD risk assessment in women.

- Alzheimer's disease (AD) and age-related macular degeneration (AMD) share several epidemiological and biochemical features. The present study aimed to assess the possible influence of the AMD-associated complement factor H (CFH) Y402H (1277T > C) polymorphism on the risk of AD. Caucasian subjects (n=800) meeting the criteria for probable (n = 717) or definite (n = 83) AD and Caucasian non-demented controls (n 1265) were included in this multi-center case-control study, in which genotype and allele frequencies of the CFH 1277T > C polymorphism were determined and related to diagnosis, APOE genotype, Mini-Mental State Examination score (MMSE) and the cerebrospinal fluid (CSF) biomarkers total-tau (T-tau), phospho-tau(181), (P-tau(181)), and beta-amyloid(1-42) (A beta(1-42)). The AMD-associated CFH genotypes (1277CC and 1277TC) were overrepresented in subjects with AD as compared to control individuals (P = 0.029). Positive C carrier status was associated with an odds ratio (OR) for AD of 1.24 (95% confidence interval [CI] 1.02-1.50). When APOE 4 carrier status was included in the regression model, this association was even stronger (OR 1.34, 95% CI: 1.08-1.65, P=0.007). Subgroup analysis showed that the association between CFH C allele positivity and AD was only evident for individuals carrying the APOE epsilon 4 allele. Positive C carrier status was also associated with lower levels of CSF A beta(1-42) selectively in the control group in an APOE epsilon 4-independent manner (P=0.003). In conclusion, the CFH 1277T > C polymorphism seems to influence the risk of AD and there appears to be an interaction between CFH 1277C and APOE epsilon 4 alleles. The CFH 1277C allele may predispose patients for co-morbidity in AD and AMD. (c) 2007 Wiley-Liss, Inc.

- OBJECTIVES: To examine whether total serum homocysteine (tHcy) in a population-based sample of middle-aged women is an independent risk factor for presence of lacunar infarcts (LIs) 24 years later. DESIGN: Prospective population study, follow-up time 24 years. SETTING: Gothenburg, an urban area in western Sweden. PARTICIPANTS: Five hundred twenty-six women, 89.6% of the original study sample of the Population Study of Women in Gothenburg, aged 46 to 60 at baseline in 1968/69 and re-examined at age 70 to 84. MEASUREMENTS: After 24 years of follow-up, all subjects underwent a psychiatric examination, and 277 computerized tomography (CT) scans of the brain were performed. Two radiologists assessed LIs and white matter lesions (WMLs). Baseline serum tHcy was analyzed from frozen stored serum samples. Logistic regression analyses were performed controlling for potential confounders such as age and selected cardiovascular risk factors. RESULTS: Thirty-four subjects had LIs in 1992 (12.3%). In the full multivariate-adjusted stepwise model, LIs were associated with elevated tHcy (odds ratio (OR)=1.09, 95% confidence interval (CI)=1.01-1.17 per micromol/L of tHcy increment). Women with tHcy values in the highest tertile were almost three times as likely to have LIs (OR=2.82, 95% CI=1.34-5.93) as were those in the lowest tertile. tHcy was not related to WMLs. Subjects who did not undergo a CT scan did not differ from those who did regarding tHcy or any of the covariates studied. CONCLUSION: tHcy in middle-aged women is an independent risk factor for LIs, but not WMLs, as observed using CT later in life.
