- Background and Aim: Low serum levels of antioxidant vitamins are associated with coronary artery disease (CAD). An immunomodulatory effect of antioxidants has been proposed. The aim of the study was to investigate whether an increased immune response in CAD patients was associated with suppressed circulating levels of antioxidant vitamins. Methods and Results: Forty-four men with stable angina and angiographically verified CAD were included as well as 69 healthy controls. T cell subsets in peripheral blood were quantified by 3-colour flow cytometry. C-reactive protein (CRP), soluble interleukin-2 receptor (sIL-2R) and the lipophilic antioxidants a-tocopherol, ß-carotene and lycopene were determined in serum. Compared with controls, patients had signs of an enhanced inflammatory activity assessed by significantly increased levels of CRP, sIL-2R and CD4+CD25+T cell subsets. Patients also had significantly lower ß-carotene and lycopene levels whereas a-tocopherol levels did not differ. The increased inflammatory/immune parameters in patients showed a significant inverse relationship to serum ß-carotene but not to lycopene or a-tocopherol. Conclusions: Low serum ß-carotene in CAD patients reflects activation of the immune system. Inflammation should be considered as an important confounding factor when analysing data on ß-carotene and CAD. © 2003, Medikal Press.

- Background and aims: Islet function is regulated by islet autonomic nerves. These nerves harbour not only the classical neurotransmitters, acetyl choline and noradrenaline, but also neuropeptides. This study examined whether the neuropeptides, pituitary adenylate cyclase activating polypeptide (PACAP) and gastrin releasing polypeptide (GRP) contribute to the regulation of insulin secretion in model experiments by using receptor gene deleted mice. Methods: Anaesthetized mice with genetic deletion of one of the PACAP receptors (PAC1 receptors) or one of the GRP receptors (GRP receptor) or their wildtype counterparts were given glucose through a gastric gavage (1150 mg) or intravenously (0.25, 0.50 or 1 g/kg). Blood samples were taken regularly during the following 120 min (after gastric glucose) or at 1 min (after intravenous glucose) for analysis of glucose and insulin. Results: The insulin response to gastric glucose was suppressed by 66% in PAC1 receptor gene deleted mice in association with impaired glucose elimination, whereas the insulin response to intravenous glucose was impaired by 36% only. The insulin response to glucose was suppressed in GRP receptor gene deleted mice by 24% together with impaired glucose elimination, whereas the insulin response to intravenous glucose was not significantly suppressed. Conclusions: The insulin responses to gastric versus intravenous glucose in receptor gene deleted mice show that PACAP, and to a lesser extent GRP, contributes to the insulin response to gastric administration of glucose.

- Recently, the National Cholesterol Education Panel (NCEP) of the United States of America commented on the implications of new clinical trials for the Adult Treatment Panel III (ATP III) guidelines [Grundy SM, Cleeman JI, Merz CN, Brewer Jr HB, Clark LT, Hunninghake DB, et al. Implications of recent clinical trials for the National Cholesterol Education Program Adult Treatment Panel III guidelines. Circulation 2004,110:227-39]. In this commentary, new categories of "moderately high" and "very high" coronary risk were proposed with new "therapeutic options" for low-density lipoprotein (LDL) cholesterol of ≤ 100 mg/dL and ≤70 mg/dL respectively. In ATP III, these "moderately high" risk patients had been classified as moderate risk with an LDL treatment goal of ≤130 mg/dL, while the "very high" risk patients had been classified as high risk with a treatment goal of ≤100 mg/dL. Risk classification in the new NCEP publication is based essentially on the combination of the Framingham risk score plus counting of classical risk factors. In the present document, the International Task Force for Prevention of Coronary Heart Disease responds to this NCEP commentary and supports the suggestion of more intensive LDL cholesterol lowering in particular cases. However, the Task Force feels that a classification based on a combination of a risk score plus a count of emerging risk factors is a more logical way to identify such patients requiring lower LDL cholesterol levels than a scheme in which classical risk factors are taken into account twice, once in a count and once in a risk score. © 2005 Elsevier B.V.

- Background and aims: The positive and negative health effects of dietary carbohydrates are of interest to both researchers and consumers. Methods: International experts on carbohydrate research held a scientific summit in Stresa, Italy, in June 2013 to discuss controversies surrounding the utility of the glycemic index (GI), glycemic load (GL) and glycemic response (GR). Results: The outcome was a scientific consensus statement which recognized the importance of postprandial glycemia in overall health, and the GI as a valid and reproducible method of classifying carbohydrate foods for this purpose. There was consensus that diets low in GI and GL were relevant to the prevention and management of diabetes and coronary heart disease, and probably obesity. Moderate to weak associations were observed for selected cancers. The group affirmed that diets low in GI and GL should always be considered in the context of diets otherwise understood as healthy, complementing additional ways of characterizing carbohydrate foods, such as fiber and whole grain content. Diets of low GI and GL were considered particularly important in individuals with insulin resistance. Conclusions: Given the high prevalence of diabetes and pre-diabetes worldwide and the consistency of the scientific evidence reviewed, the expert panel confirmed an urgent need to communicate information on GI and GL to the general public and health professionals, through channels such as national dietary guidelines, food composition tables and food labels.

- BACKGROUND AND AIM: The sympathetic nervous system may be involved in the pathophysiology of insulin resistance and metabolic cardiovascular syndrome in young men. The aim was to study the effects of long-term stress on different features of the metabolic syndrome (MES) in formerly non-obese healthy young males during 5 months of defined conditions. METHODS AND RESULTS: Sixteen healthy male sailors (mean age 36.5 (SD)+/-7 years) participating in a sailing race around the world were recruited for the study. Investigations were done before the start and at stop overs after finishing laps 1, 2 and 4 (1, 2(1/2) and 5 months, respectively). Anthropometric and blood pressure data as well as biochemical data associated with MES were substantiated. Food intake and exercise were chartered and largely controlled. A mean weight loss of 4.5+/-2 kg (P<0.005), comprising both fat and lean body mass, was recorded during the first lap. Subsequently after 5 months, a weight gain, mainly consisting of 1.2+/-1.1 kg body fat (P<0.05), took place, concomitantly with a protein mass drop of 0.6+/-1.1 kg (P<0.05). The body fat gain accumulated on the abdominal region. Elevated blood levels of HbA1c, insulin and the triglycerides/high-density lipoprotein ratio were also observed during the race. Likewise heart rate and systolic blood pressure increased slightly but to a statistically significant extent. CONCLUSIONS: Non-obese healthy young men exposed to long-term stress developed abdominal obesity and signs of a metabolic syndrome in embryo, also emphasized by biochemical and blood pressure alterations. It is suggested that long-term and sustained stress activation might be an additional risk factor for the development of MES, even after control of dietary and exercise habits.

- BACKGROUND AND AIMS: Impaired glucose tolerance (IGT) is regarded as a transient metabolic state leading to type-2 diabetes, and is known to predict future risk of cardiovascular disease. This study was designed to investigate if IGT is associated with subclinical atherosclerosis. METHODS AND RESULTS: In a population-based cohort of 64-year-old women, a group with IGT determined by repeated oral glucose tolerance tests (n=205) was compared with healthy women with normal glucose tolerance (NGT, n=188). Intima-media thickness (IMT) and plaques in the common carotid arteries (CCA) and bulbs were measured by ultrasound. The 95% confidence interval (CI) of the difference between the IGT and NGT groups was -0.03 to 0.03mm. There was no difference in carotid bulb IMT or in the occurrence, size, and characteristics of plaques between the IGT and NGT groups. A meta-analysis was used to calculate summary measures of 12 reviewed studies showing a difference of 0.030 (95% CI 0.012-0.048) mm in carotid IMT between IGT and NGT groups. Heterogeneity in IMT differences between studies was shown. CONCLUSIONS: In our population-based cohort of 64-year-old women, IGT was not associated with increased occurrence of subclinical atherosclerosis. However, a meta-analysis of 12 studies, including our current study, showed that IGT was associated with a small increase in the CCA IMT.

- Type I hyperlipoproteinemia, also known as familial chylomicronemia syndrome (FCS), is a rare autosomal recessive disorder caused by variants in LPL, APOC2, APOA5, LMF1 or GPIHBP1 genes. The aim of this study was to identify novel variants in the LPL gene causing lipoprotein lipase deficiency and to understand the molecular mechanisms.A total of 3 individuals with severe hypertriglyceridemia and recurrent pancreatitis were selected from the Lipid Clinic at Sahlgrenska University Hospital and LPL was sequenced. Invitro experiments were performed in human embryonic kidney 293T/17 (HEK293T/17) cells transiently transfected with wild type or mutant LPL plasmids. Cell lysates and media were used to analyze LPL synthesis and secretion. Media were used to measure LPL activity. Patient 1 was compound heterozygous for three known variants: c.337T>C (W113R), c.644G>A (G215E) and c.1211T>G (M404R); patient 2 was heterozygous for the known variant c.658A>C (S220R) while patient 3 was homozygous for a novel variant in the exon 5 c.679G>T (V227F). All the LPL variants identified were loss-of-function variants and resulted in a substantial reduction in the secretion of LPL protein.We characterized at the molecular level three known and one novel LPL variants causing type I hyperlipoproteinemia showing that all these variants are pathogenic.

- Aim: To study waist-hip ratio (WHR), waist circumference (WC), sagittal abdominal diameter (SAD), and waist-hip-height ratio (WHHR) as predictors of CVD, in men and women stratified by BMI (cut-off >= 25). Methods and results: A cohort of n = 3741 (53% women) 60-year old individuals without CVD was followed for 11-years (375 CVD cases). To replicate the results, we also assessed another large independent cohort; The Malmo Diet and Cancer study - cardiovascular cohort (MDCC, (n = 5180, 60% women, 602 CVD cases during 16-years). After adjustment for established risk factors in normal-weight women, the hazard ratio (HR) per one standard deviation (SD) were; WHR; 1.91 (95% confidence interval (CI) 1.35-2.70), WC; 1.81 (95% CI 1.02-3.20), SAD; 1.25 (95% CI 0.74-2.11), and WHHR; 1.97 (95% CI 1.40-2.78). In men the association with WHR, WHHR and WC were not significant, whereas SAD was the only measure that significantly predicted CVD in men (HR 1.19 (95% CI 1.04-1.35). After adjustments for established risk factors in overweight/obese women, none of the measures were significantly associated with CVD risk. In men, however, all measures were significant predictors; WHR; 1.24 (955 CI 1.04-1.47), WC 1.19 (95% CI 1.00-1.42), SAD 1.21 (95% CI 1.00-1.46), and WHHR; 1.23 (95% CI 1.05-1.44). Only the findings in men with BMI >= 25 were verified in MDCC. Conclusion: In normal weight individuals, WHHR and WHR were the best predictors in women, whereas SAD was the only independent predictor in men. Among overweight/obese individuals all measures failed to predict CVD in women, whereas WHHR was the strongest predictor after adjustments for CVD risk factors in men.

Tidskriftsartikel (refereegranskat)abstract
- Background and aims: Immigrant women from the Middle East have higher cardiovascular risk compared to native women. Whether low antioxidant intake, oxidative stress or inflammation contributes to risk is unknown. In a cross-sectional study of 157 randomly selected foreign-born women (Iranian and Turkish) and native women living in Sweden, we investigated antioxidant status, oxidative stress (F-2-isoprostanes) and systemic inflammation (plasma high sensitive C-reactive protein; CRP) markers. We also investigated relationships between F2-isoprostanes, CRP and cardiovascular risk factors. Methods and result: Dietary intake was assessed using 24-h dietary recalls repeated four times. Micronutrient intake was not consistently different between groups. Serum a-tocopherol, but not gamma-tocopherot levels, was tower in Turkish vs. Swedish women (P < 0.05). Turkish women had the highest F-2-isoprostane levels (P < 0.05 vs. Iranian women) and CRP levels (P < 0.01 vs. Swedish women and P = 0.05 vs. Iranian women). In immigrants (n = 97), F-2-isoprostanes correlated positively to insulin levels (r = 0.31, P < 0.01), and CRP was correlated to obesity and several cardiovascular risk factors (r-values >0.21, P values <0.05). Conclusion: The rote of antioxidant status is unclear, whereas signs of oxidative stress and inflammation are evident in immigrant women from Middle East, especially Turkish women. Oxidative stress and low-grade inflammation might contribute to the higher cardiovascular risk previously observed in immigrant women. Further larger studies adjusting for more potential confounders are motivated to confirm these results.

- Background and aims: CCAAT/enhancer-binding protein alpha (CEBPA) is a transcription factor involved in adipogenesis and energy homeostasis. Caloric restriction reduces CEBPA protein expression in patients with metabolic syndrome (MetS). A previous report linked rs12691 SNP in CEBPA to altered concentration of fasting triglycerides. Our objective was to assess the effects of rs12691 in glucose metabolism in Metabolic Syndrome (MetS) patients. Methods and results: Glucose metabolism was assessed by static (glucose, insulin, adiponectin, leptin and resistin plasma concentrations) and dynamic (disposition index, insulin sensitivity index, HOMA-IR and acute insulin response to glucose) indices, performed at baseline and after 12 weeks of 4 dietary interventions (high saturated fatty acid (SFA), high monounsaturated fatty acid (MUFA), low-fat and low-fat-high-n3 polyunsaturated fatty acid (PUFA)) in 486 subjects with MetS. Carriers of the minor A allele of rs12691 had altered disposition index (p = 0.0003), lower acute insulin response (p = 0.005) and a lower insulin sensitivity index (p = 0.025) indicating a lower insulin sensitivity and a lower insulin secretion, at baseline and at the end of the diets. Furthermore, A allele carriers displayed lower HDL concentration. Conclusion: The presence of the A allele of rs12691 influences glucose metabolism of MetS patients. Clinical Trials Registry number NCT00429195.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND AND AIMS: Vanin-1 (gene name VNN1) is an enzyme with pantetheinase activity generating the amino-thiol cysteamine which is implicated in the regulation of red-ox status through its effect on glutathione. We tested the hypothesis that the rs2294757 VNN1 T26I polymorphism could affect blood pressure (BP) levels, hypertension prevalence, and risk of incident cardiovascular events. METHODS AND RESULTS: The VNN1 T26I polymorphism was genotyped in 5664 participants of the cardiovascular cohort of the "Malmö Diet and Cancer" (MDC-CVA) study and successively in 17874 participants of the "Malmö Preventive project"(MPP). The incidence of cardiovascular events was monitored for an average of nearly 12 years of follow-up in the MDC-CVA and for 25 years in the MPP. Both before and after adjustment for sex, age and BMI in the MDC-CVA the polymorphism had a mild lowering effect on diastolic BP and hypertension, especially in females. However in MPP no effect on BP phenotypes was detectable. Before and after adjustment for major cardiovascular risk factors, the hazard ratio for incident ischemic stroke and coronary events in the MDC-CVA was not significantly different in carriers of different genotypes. CONCLUSIONS: Our data do not support a major role for the VNN1 T26I variant in determining BP level and incident ischemic events.

- Background and aims: Increased body mass index (BMI) has been associated with increased cardiovascular morbidity and mortality in hypertension. Less is known about the impact of BMI on improvement in left ventricular (LV) structure and function during antihypertensive treatment. Methods and results: Annual BMI, echocardiograms and cardiovascular events were recorded in 875 hypertensive patients with LV hypertrophy during 4.8 years randomized treatment in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) echocardiography substudy. Patients were grouped by baseline BMI into normal (n = 282), overweight (n = 405), obese (n = 150) and severely obese groups (n = 38) (BMI <= 24.9, 25.0-29.9, 30.0-34.9, and >= 35.0 kg/m(2), respectively). At study end, residual LV hypertrophy was present in 54% of obese and 79% of severely obese patients compared to 31% of normal weight patients (both p < 0.01). In regression analyses, adjusting for initial LV mass/height(2.7), higher BMI predicted less LV hypertrophy reduction and more reduction in LV ejection fraction (both p < 0.05), independent of blood pressure reduction, diabetes and in-study weight change. During follow-up, 91 patients suffered cardiovascular death, myocardial infarction or stroke. In Cox regression analysis 1 kg/m(2) higher baseline BMI predicted a 5% higher rate of cardiovascular events and 10% higher cardiovascular mortality over 4.8 years (both p < 0.05). Conclusions: In hypertensive patients in the LIFE study, increased BMI was associated with less reduction of LV hypertrophy and less improvement in LV systolic function which may contribute to the observed higher cardiovascular event rate of treated hypertensive patients.

- Background and Aim: Ceramides are poorly characterized in human adipose tissue. The aim of this study was to investigate concentrations of different ceramide species in human subcutaneous and visceral adipose tissue depots and to determine associations between ceramides and global gene expression profiles. Methods and Results: Concentrations of six ceramide species were determined in plasma and in subcutaneous and mediastinal adipose tissue from 10 overweight subjects (BMI 29.4±4.9kg/m2). In the adipose tissue biopsies gene expression arrays were performed and relationships between ceramides and gene expression analyzed. Immunostaining of the two adipose tissue depots was performed in an independent group of 10 patients. Mediastinal adipose tissue contained significantly higher concentrations (p<0.05) of all six ceramide species than the subcutaneous depot. Of the six ceramides in plasma, concentrations of only two (Cer d18:1/18:0 and Cer d18:1/22:0) correlated significantly (p<0.05) with the corresponding species in mediastinal adipose tissue, but there were no significant correlations between ceramides in plasma and subcutaneous adipose tissue. Multivariate analysis identified significant correlations between the total ceramide concentration and global gene expression within mediastinal, but not subcutaneous adipose tissue, according to cross-validation. Gene ontology analysis of genes related to ceramides in the mediastinal depot revealed that genes positively correlated with ceramides were associated mainly with immune and inflammatory categories, while genes negatively correlated with ceramides were associated mainly with lipid and carbohydrate metabolism. Conclusions: Ceramides in human mediastinal adipose tissue may be involved in inflammation and lipid and carbohydrate metabolism. © 2013 Elsevier B.V.

- Aim To evaluate whether a moderate supplementation of long-chain n-3 fatty acids is able to modulate insulin sensitivity, insulin secretion, β-cell function and glucose tolerance in healthy individuals consuming a diet rich in either saturated or monounsaturated fat, also in relation to their habitual dietary intake of n-6 and n-3 fatty acid. Methods and results One hundred and sixty-two healthy individuals were randomly assigned to follow either one of two isoenergetic diets for 3months, one rich in monounsaturated fats and the other rich in saturated fats. Within each group there was a second randomisation to fish oil (n-3 fatty acids 3.6g/day) or placebo. At the beginning and at the end of the treatment periods insulin sensitivity (SI), first phase insulin response (FPIR) and glucose tolerance (KG-value) were evaluated by the intravenous glucose tolerance test (IVGTT). Fish oil did not have any effect on SI, FPIR, KG-value and disposition index in either diet. Even after dividing subjects according to the median value of n-6/n-3 ratio of serum phospholipids at baseline, there was no change in SI (Δ SI 0.42±0.34 on fish oil vs 0.14±0.23 on placebo for those with n-6/n-3 <4.85; −1.03±0.47 on fish oil vs −0.27±0.32 on placebo for those with n-6/n-3 >4.85) (M±SE), FPIR (Δ FPIR 135.9±78.9 vs 157.2±157.5pmol/L; 38.8±181.7 vs 357.1±181.7pmol/L), KG-value (Δ KG 0.14±0.15 vs 0.12±0.11; −0.32±0.16 vs 0.15±0.15) or disposition index (Δ disposition index 1465.4±830.4 vs 953.8±690.0; −1641.6±1034.3 vs 446.6±905.1). Considering the 75th percentile of n-6/n-3 ratio (5.82) the results on insulin sensitivity, insulin secretion and disposition index were confirmed, while, in this more extreme situation, n-3 fatty acid supplementation induced a significant deterioration of KG-value (p=0.02). Conclusions In healthy individuals a moderate supplementation of fish oil does not affect insulin sensitivity, insulin secretion, β-cell function or glucose tolerance. The same is true even when the habitual dietary intake of n-6 and n-3 fatty acids is taken into account.

- Background and Aims Lipid oversupply to cardiomyocytes or decreased utilization of lipids leads to cardiac steatosis. We aimed to examine the role of different circulating metabolic biomarkers as predictors of myocardial triglyceride (TG) content in non-diabetic men. Methods and Results Myocardial and hepatic TG contents were measured with 1.5 T magnetic resonance (MR) spectroscopy, and LV function, visceral adipose tissue (VAT), abdominal subcutaneous tissue (SAT), epicardial and pericardial fat by MR imaging in 76 non-diabetic men. Serum concentration of circulating metabolic biomarkers [adiponectin, leptin, adipocyte-fatty acid binding protein 4 (A-FABP 4), resistin, and lipocalin-2] including ß-hydroxybuturate (ß-OHB) were measured. Subjects were stratified by tertiles of myocardial TG into low, moderate, and high myocardial TG content groups. Concentrations of ß-OHB were lower (p=0.003) and serum levels of A-FABP 4 were higher (p<0.001) in the group with high myocardial TG content compared with the group with low myocardial TG content. ß-OHB was negatively correlated with myocardial TG content (r= -0.316, p=0.006), whereas A-FABP 4 was not correlated with myocardial TG content (r=0.192, p=0.103). In multivariable analyses ß-OHB and plasma glucose levels were the best predictors of myocardial TG content independently of VAT and hepatic TG content. The model explained 58.8% of the variance in myocardial TG content. Conclusion Our data showed that ß-OHB and fasting gluocse were the best predictors of myocardial TG content in non-diabetic men. These data suggest that hyperglycemia and alterations in lipid oxidation may be associated with cardiac steatosis in humans.

- Background and aims: The Metabolic Syndrome (MetS) is associated with increased cardiovascular risk. Circulating microparticles (MP) are involved in the pathogenesis of atherothrombotic disorders and are raised in individual with CVD. We measured their level and cellular origin in subjects with MetS and analyzed their associations with 1/anthropometric and biological parameters of MetS, 2/inflammation and oxidative stress markers. Methods and results: Eighty-eight subjects with the MetS according to the NCEP-ATPIII definition were enrolled in a bicentric study and compared to 27 healthy controls. AnnexinV-positive MP (TMP), MP derived from platelets (PMP), erythrocytes (ErMP), endothelial cells (EMP), leukocytes (LMP) and granulocytes (PNMP) were determined by flow cytometry. MetS subjects had significantly higher counts/mu l of TMP (730.6 +/- 49.7 vs 352.8 +/- 35.6), PMP (416.0 +/- 43.8 vs 250.5 +/- 23.5), ErMP (243.8 +/- 22.1 vs 73.6 +/- 19.6) and EMP (7.8 +/- 0.8 vs 4.0 +/- 1.0) compared with controls. LMP and PNMP were not statistically different between groups. Multivariate analysis demonstrated that each criterion for the MetS influenced the number of TMP. Waist girth was a significant determinant of PMP and EMP level and blood pressure was correlated with EMP level. Glycemia positively correlated with PMP level whereas dyslipidemia influenced EMP and ErMP levels. Interestingly, the oxidative stress markers, plasma glutathione peroxy-dase and urinary 8-iso-prostaglandin F(2) alpha, independently influenced TMP and PMP levels whereas inflammatory markers did not, irrespective of MP type. Conclusion: Increased levels of TMP, PMP, ErMP and EMP are associated with individual metabolic abnormalities of MetS and oxidative stress. Whether MP assessment may represent a marker for risk stratification or a target for pharmacological intervention deserves further investigation.

- BACKGROUND AND AIMS: This study aimed to expand the European Prospective Investigation into Cancer and Nutrition (EPIC) nutrient database (ENDB) by adding amino acid (AA) values, using the U.S. nutrient database (USNDB). Additionally, we aimed to evaluate these new protein and AA intake estimates from the EPIC dietary questionnaires (DQ) and 24-h dietary recalls (24-HDR) using different matching procedures.METHODS AND RESULTS: Dietary energy, protein and AA intakes were assessed via DQ and 24-HDR by matching with the USNDB food composition table. Energy and protein intakes calculated using USNDB matching were compared with those calculated using ENDB, that uses country specific food composition tables. Pearson correlations, Cohen's weighted kappa statistic and Bland-Altman plots were used to compare data resulting from USNDB matching with our reference from ENDB matching. Very high correlations were found when comparing daily energy (r = 0.99) and dietary protein intakes (r = 0.97) assessed via USNDB with those obtained via ENDB (matching for DQ and 24-HDR). Significant positive correlations were also found with energy and protein intakes acquired via 24-HDRs in the EPIC calibration sample.CONCLUSION: Very high correlations between total energy and protein intake obtained via the USDA matching and those available in ENDB suggest accuracy in the food matching. Individual AA have been included in the extended EPIC Nutrient database that will allow important analyses on AA disease prospective associations in the EPIC study.

Tidskriftsartikel (refereegranskat)abstract
- The cardiovascular risk conferred by concomitant prediabetes in hypertension is unclear. We aimed to examine the impact of prediabetes on incident heart failure (HF) and all-cause mortality, and to describe time in therapeutic blood pressure range (TTR) in a hypertensive real-world primary care population.In this retrospective cohort study, 9628 hypertensive individuals with a fasting plasma glucose (FPG) in 2006-2010 but no diabetes, cardiovascular or renal disease were followed to 2016; median follow-up was 9 years. Prediabetes was defined as FPG 5.6-6.9mmol/L, and in a secondary analysis as 6.1-6.9mmol/L. Study outcomes were HF and all-cause mortality. Hazard ratios (HR) were compared for prediabetes with normoglycemia using Cox regression. All blood pressure values from 2001 to the index date (first FPG in 2006-2010) were used to calculate TTR. At baseline, 51.4% had prediabetes. The multivariable-adjusted HR (95% confidence intervals) was 0.86 (0.67-1.09) for HF and 1.06 (0.90-1.26) for all-cause mortality. For FPG defined as 6.1-6.9mmol/L, the multivariable-adjusted HR were 1.05 (0.80-1.39) and 1.42 (1.19-1.70), respectively. The prediabetic group had a lower TTR (p<0.05).Prediabetes was not independently associated with incident HF in hypertensive patients without diabetes, cardiovascular or renal disease. However, prediabetes was associated with all-cause mortality when defined as FPG 6.1-6.9mmol/L (but not as 5.6-6.9mmol/L). TTR was lower in the prediabetic group, suggesting room for improved blood pressure to reduce incident heart failure in prediabetes.

Tidskriftsartikel (refereegranskat)abstract
- Background and aims: Diabetes mellitus is a well-known risk factor for cardiovascular disease, and brings an increased risk of vascular events and a higher mortality rate. Treatment guidelines recommend statins in patients with diabetes, with low-density lipoprotein cholesterol (LDL-C) targets of 100 mg dl(-1) (similar to 2.5 mmol l(-1)), and 80 (similar to 2.0 mmol l(-1)) or 70 mg dl(-1) (similar to 1.8 mmol l(-1)) in especially high-risk patients. The current study used the VOYAGER (an indiVidual patient data-meta-analysis Of statin therapY in At risk Groups: Effects of Rosuvastatin, atorvastatin, and simvastatin) database to characterise effects of rosuvastatin, atorvastatin and simvastatin in different doses on lipid levels in diabetes patients. Methods and results: The VOYAGER database included individual patient data from 37 studies involving comparisons of rosuvastatin with either atorvastatin or simvastatin. Of the 32 258 patients included, 8859 (27.5%) had diabetes. Rosuvastatin appeared to be the most efficacious of the three statins, both for lowering LDL-C and for reaching a target level of <70 mg dl(-1) for LDL-C. It was also more effective than atorvastatin at raising high-density lipoprotein cholesterol in the diabetes population. These results are consistent with the overall VOYAGER results. Conclusions: This meta-analysis of 8859 patients with diabetes mellitus shows favourable effects on lipids with the three statins studied, in line with results for the overall VOYAGER population. The importance of using an effective statin at an effective dose to reach treatment goals for such high-risk patients is evident. (c) 2012 Elsevier B.V. All rights reserved.

Tidskriftsartikel (refereegranskat)abstract
- Background and aims: This multicentre European study evaluated, in a young-to-middle-aged healthy population without carotid atherosclerosis, the gender-related differences in carotid intima-media thickness (IMT) and its short-term (3-year) progression, and whether these differences are related to different vascular ageing rate, cardiovascular risk profile or different susceptibility to family predisposition to cardiovascular diseases (CVD). Methods and results: 366 men and 422 women (age between 30 and 60 years) underwent B-mode carotid ultrasound at baseline and after 3-year follow-up period. IMT in 3 carotid segments was higher in men than in women (p < 0.0001 for all segments). When evaluated according to age decade, differences between men and women disappeared in the 6th decade, as in this decade a 3-year IMT progression rate accelerated in women (p < 0.05 as compared to the 4th and 5th age decade). Age was a major determinant of baseline all-segment IMT in women; in men all-segment IMT was influenced by age and LDL-cholesterol. IMT progression did not correlate with established cardiovascular risk factors, their short-term changes or family predisposition to CVD. Yet, a 3-year IMT progression in common carotid artery (CCA) was higher in men (p = 0.01) and women (p < 0.01) in whom relative Framingham risk increased during the corresponding period. Conclusion: This study provides reference values on IMT and its short-term progression in healthy young-to-middle-aged population, and demonstrates gender-related differences in the susceptibility of carotid wall to ageing and LDL-cholesterol. Increase in Framingham risk accelerated a short-term CCA IMT progression rate in both genders, whereas family predisposition to CVD did not influence carotid IMT. (C) 2011 Elsevier B. V.

- Background and aims: The respective roles of dietary fatty acids in the pathogenesis of diabetes are as yet unclear. Erythrocyte membrane fatty acid (EMFA) composition may provide an estimate of dietary fatty acid intake. This study investigates the relation between EMFA composition and development of Type 2 diabetes mellitus.Methods and results: In a nested case-referent design we studied 159 individuals tested as non-diabetic at baseline who after a mean observation time of 5.4 +/- 2.6 years were diagnosed with Type 2 diabetes mellitus and 291 sex- and age-matched referents. Higher proportions of pentadecanoic acid (15: 0) and heptadecanoic acid (17:0) were associated with a tower risk of diabetes. In accordance with earlier findings, higher proportions of palmitoleic (16:1 n-7), dihomo-gamma-linotenic (20:3 n-6) and adrenic (22:4 n-6) acids were associated with increased risk, whereas linoleic (18:2 n-6) and clupanodonic (22:5 n-3) acids were inversely associated with diabetes. After adjustment for BMI, HbA1c, alcohol intake, smoking and physical activity the only significant predictors were 15:0 and 17:0 as protective factors and 22:4 n6 as risk factor.Conclusion: In accordance with previous studies, our results indicate that EMFA-patterns predict development of Type 2 diabetes mellitus. The inverse association with two saturated fatty acids, previously shown to reflect consumption of dairy products, is a new finding.

Tidskriftsartikel (refereegranskat)abstract
- Background and aim: Until recently, very few intervention studies have investigated the effects of whole-grain cereals on postprandial glucose, insulin and lipid metabolism, and the existing studies have provided mixed results. The objective of this study was to evaluate the effects of a 12-week intervention with either a whole-grain-based or a refined cereal-based diet on postprandial glucose, insulin and lipid metabolism in individuals with metabolic syndrome.Methods and results: Sixty-one men and women age range 40-65 years, with the metabolic syndrome were recruited to participate in this study using a parallel group design. After a 4-week run-in period, participants were randomly assigned to a 12-week diet based on whole-grain products (whole-grain group) or refined cereal products (control group). Blood samples were taken at the beginning and end of the intervention, both fasting and 3 h after a lunch, to measure biochemical parameters. Generalized linear model (GLM) was used for between-group comparisons. Overall, 26 participants in the control group and 28 in the whole-grain group completed the dietary intervention. Drop-outs (five in the control and two in the whole-grain group) did not affect randomization. After 12 weeks, postprandial insulin and triglyceride responses (evaluated as average change 2 and 3 h after the meal, respectively) decreased by 29% and 43%, respectively, in the whole-grain group compared to the run-in period. Postprandial insulin and triglyceride responses were significantly lower at the end of the intervention in the whole-grain group compared to the control group (p = 0.04 and p = 0.05; respectively) whereas there was no change in postprandial response of glucose and other parameters evaluated.Conclusions: A twelve week whole-grain cereal-based diet, compared to refined cereals, reduced postprandial insulin and triglycerides responses. This finding may have implications for type 2 diabetes risk and cardiovascular disease. (C) 2014 Elsevier B. V. All rights reserved.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND AND AIMS: Whole-grain cereals and diets with a low glycemic index may protect against the development of type 2 diabetes and heart disease, but the mechanisms are poorly understood. We studied the effect of carbohydrate modification on serum metabolic profiles, including lipids and branched chain amino acids, and dependencies between these and specific gene expression pathways in adipose tissue.METHODS AND RESULTS: Twenty subjects with metabolic syndrome were selected from the larger FUNGENUT study population, randomized either to a diet high in oat and wheat bread and potato (OWP) or rye bread and pasta (RP). Serum metabolomics analyses were performed using ultra-performance liquid chromatography coupled to electrospray ionization mass spectrometry (UPLC/MS), gas chromatography (GC) and UPLC. In the OWP group multiple proinflammatory lysophosphatidylcholines increased, while in the RP group docosahexaenoic acid (DHA 22:6n-3) increased and isoleucine decreased. mRNA expression of stress reactions- and adipose tissue differentiation-related genes were up-regulated in adipose tissue in the OWP group. In the RP group, however, pathways related to stress reactions and insulin signaling and energy metabolism were down-regulated. The lipid profiles had the strongest association with the changes in the adipose tissue differentiation pathway when using the elastic net regression model of the lipidomic profiles on selected pathways.CONCLUSION: Our results suggest that the dietary carbohydrate modification alters the serum metabolic profile, especially in lysoPC species, and may, thus, contribute to proinflammatory processes which in turn promote adverse changes in insulin and glucose metabolism.

Tidskriftsartikel (refereegranskat)abstract
- Background and aims: Polyphenol-rich foods have beneficial properties that may lower cardiometabolic risk. We aimed to prospectively investigate the relationship between intakes of dietary polyphenols, and metabolic syndrome (MetS) and its components, in 676 Danish residents from the MAX study, a subcohort of the Danish Diet, Cancer and Health–Next Generations (DCH-NG) cohort. Methods and results: Dietary data were collected using web-based 24-h dietary recalls over one year (at baseline, and at 6 and 12 months). The Phenol-Explorer database was used to estimate dietary polyphenol intake. Clinical variables were also collected at the same time point. Generalized linear mixed models were used to investigate relationships between polyphenol intake and MetS. Participants had a mean age of 43.9y, a mean total polyphenol intake of 1368 mg/day, and 75 (11.6%) had MetS at baseline. Compared to individuals with MetS in Q1 and after adjusting for age, sex, lifestyle and dietary confounders, those in Q4 – for total polyphenols, flavonoids and phenolic acids–had a 50% [OR (95% CI): 0.50 (0.27, 0.91)], 51% [0.49 (0.26, 0.91)] and 45% [0.55 (0.30, 1.00)] lower odds of MetS, respectively. Higher total polyphenols, flavonoids and phenolic acids intakes as continuous variable were associated with lower risk for elevated systolic blood pressure (SBP) and low high-density lipoprotein cholesterol (HDL-c) (p < 0.05). Conclusions: Total polyphenol, flavonoid and phenolic acid intakes were associated with lower odds of MetS. These intakes were also consistently and significantly associated with a lower risk for higher SBP and lower HDL-c concentrations.

Tidskriftsartikel (refereegranskat)abstract
- Background and aims: Coffee contains many biologically active compounds with potential adverse or beneficial effects on the cardiovascular system. Whether coffee consumption is associated with the risk of aortic valve stenosis (AVS) is unknown. The purpose of this study was therefore to examine the association between coffee consumption and AVS incidence.Methods and results: This prospective study included 71 178 men and women who provided information on their coffee consumption through a questionnaire at baseline. Incident cases of AVS were identified through linkage with the Swedish National Patient and Cause of Death Registers. During a mean follow-up of 15.2 years, 1295 participants (777 men and 518 women) were diagnosed with AVS. Coffee consumption was positively associated with risk of AVS in a dose - response manner after adjustment for age, sex, smoking, and other risk factors (P-trend = 0.005). The multivariable hazard ratios were was 1.11 (95% confidence interval 1.04 - 1.19) per 2 cups/day increase of coffee consumption and 1.65 (95% confidence interval 1.10 - 2.48) when comparing the highest (>= 6 cups/day) with the lowest (<0.5 cup/day) category of coffee consumption. The association was not modified by other risk factors.Conclusions: This study provides novel evidence that high coffee consumption is associated with an increased risk of AVS.

- Background and aims: The impact of vitamin D concentrations on subsequent cardiovascular disease (CVD) and overall mortality has been generally examined for periods under two decades. The magnitude of the association may depend on follow-up length. We aimed to investigate the relationship between baseline vitamin D and risk of total CVD, stroke and all-cause mortality over three decades of follow-up. Secondly, we aimed to assess how follow-up affects the associations. Methods and results: Concentrations of 25-hydroxyvitamin D (25D) were measured in a population-based sample of 1227 middle-aged women using serum collected at baseline and categorized into low (lowest 25D quartile) vs high 25D status (upper three 25D quartiles). Hazard ratio (HR) of the endpoints was estimated for low 25D. The impact of follow-up was examined in intermediary analyses where follow-up was interrupted up to four times, each time decreasing it by five years. There were 596 cardiovascular events and 635 participants died. During the first 17 years, the low 25D group experienced a 29% higher CVD risk and 3.3-fold higher stroke risk after accounting for confounders. Longer follow-up diminished significantly these risks and 25D status had no contribution at 32 years. For mortality, the decline over time was less dramatic, with HR = 1.96 (1.25; 3.08) at 17 years and HR = 1.42 (1.17; 1.72) at 37 years. Conclusion: Low 25D status increased the risk for all endpoints, but a lengthy follow-up diminished these risks towards the null. The impact of follow-up depends on the outcome. Future studies of 25D and disease should use repeated 25D assessments.

- Background and aims: Low circulating levels of carotenoids have been associated with cardiovascular disease. The distribution of different carotenoids in blood may have an impact on the cardioprotective capacity. The aim of the present study was to determine the plasma levels of 6 major carotenoids in patients with coronary artery disease (CAD) and relate the findings to clinical, metabolic and immune parameters. Methods and results: Plasma levels of oxygenated carotenoids (lutein, zeaxanthin, β-cryptoxanthin) and hydrocarbon carotenoids (α-carotene, β-carotene, lycopene) were determined in 39 patients with acute coronary syndrome, 50 patients with stable CAD and 50 controls. Serological assays for inflammatory activity and flow cytometrical analysis of lymphocyte subsets were performed. Both patient groups had significantly lower plasma levels of oxygenated carotenoids, in particular lutein + zeaxanthin, compared to controls. Low levels of oxygenated carotenoids were associated with smoking, high body mass index (BMI), low high density lipoprotein (HDL) cholesterol and, to a minor degree, inflammatory activity. Plasma levels of lutein + zeaxanthin were independently associated with the proportions of natural killer (NK) cells, but not with other lymphocytes, in blood. Conclusion: Among carotenoids, lutein + zeaxanthin and β-cryptoxanthin were significantly reduced in CAD patients independent of clinical setting. The levels were correlated to a number of established cardiovascular risk factors. In addition, the relationship between NK cells and lutein + zeaxanthin may indicate a particular role for certain carotenoids in the immunological scenario of CAD. © 2006 Elsevier B.V.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND AND AIMS: An increased amount of visceral adipose tissues has been related to atherosclerosis and future cardiovascular events. The present study aims to investigate how the abdominal fat distribution links to plasma levels of cardiovascular-related proteins.METHOD AND RESULTS: In the Prospective investigation of Obesity, Energy and Metabolism (POEM) study (n = 326, all aged 50 years), abdominal visceral (VAT) and subcutaneous (SAT) adipose tissue volumes were quantified by MRI. Eighty-six cardiovascular-related proteins were measured by the proximity extension assay (PEA). Similar investigations were carried out in the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) study (n = 400, all aged 75 years). In the discovery dataset (POEM), 10 proteins were related to the VAT/SAT-ratio using false discovery rate <.05. Of those, Cathepsin D (CTSD), Interleukin-1 receptor antagonist protein (IL-1RA) and Growth hormone (GH) (inversely) were related to the VAT/SAT-ratio in the validation in PIVUS following adjustment for sex, BMI, smoking, education level and exercise habits (p < 0.05). In a secondary analysis, a meta-analysis of the two samples suggested that 15 proteins could be linked to the VAT/SAT-ratio following adjustment as above and Bonferroni-correction of the p-value.CONCLUSION: Three cardiovascular-related proteins, cathepsin D, IL-1RA and growth hormone, were being associated with the distribution of abdominal adipose tissue using a discovery/validation approach. A meta-analysis of the two samples suggested that also a number of other cardiovascular-related proteins could be associated with an unfavorable abdominal fat distribution.
