- The metabolic syndrome (MetS) is characterized by a constellation of factors that confer an increased risk for cardiovascular morbidity and mortality. It is well-known that physical activity (PA) has a protective role on cardiovascular morbidity and mortality, mainly through its favorable effects on traditional risk factors such as body mass and blood pressure (BP). We assessed the prevalence of MetS in a population-based sample of 58-year-old men with respect to leisure-time PA and also to occupational PA. The results showed an inverse linear association (P < .05) between leisure time physical activity (LTPA) and MetS in this group. In conclusion, this study suggests that PA has an important role in controlling MetS.

- Low-density lipoprotein is recognized as a primary vascular risk factor. However, recent data favor apolipoprotein (apo)B and apoA-I as risk factors with higher predictive values than conventional lipids. We investigated how leisure-time physical activity relates to the serum apoB/apoA-I ratio in middle-aged men. The results showed that compared with a sedentary lifestyle, moderate physical activity was associated with a decreased apoB/apoA-I ratio (1.01 ± 0.28 vs 0.87 ± 0.24, P < .05) and increased apoA-I levels (1.30 ± 0.20 g/L vs 1.43 ± 0.22 g/L, P < .05), whereas vigorous activity was required to observe a reduction in apoB levels (1.27 ± 0.28 g/L vs 1.14 ± 0.24 g/L, P < .05). A covariate analysis showed that leisure time physical activity was also associated with reduced apoB/apoA-I ratios after adjustment for smoking, systolic blood pressure and waist circumference. Importantly, this association was seen at moderate levels of physical activity, supporting the notion that some activity is better than none.

- We have previously described that the sodium/lithium countertransport (SLC) in the erythrocyte cell membrane is closely linked to obesity and insulin resistance. Adiponectin and retinol-binding protein 4 (RBP-4) are believed to affect obesity and insulin resistance. In the present study, we aimed to further characterize the relationship between SLC, inflammatory markers, adiponectin and RBP-4.

Ankle-Brachial Index Should Be Measured in Both the Posterior and the Anterior Tibial Arteries in Studies of Peripheral Arterial Disease

- Lower extremity peripheral artery disease (PAD) is a powerful predictor of cardiovascular events and mortality. The ankle-brachial index (ABI) is an objective and standard diagnostic method to diagnose PAD (an ABI ≤0.9 is considered pathological). The American Heart Association (AHA) and the American College of Cardiology (ACC) recommend using both the posterior- and anterior tibial arteries when assessing ABI. We investigated if there was a difference in the diagnosis of PAD if the ABI was measured in the posterior- or the anterior tibial artery. The results showed that among subjects with ABI ≤0.9, between 30% and 40% would not get a PAD diagnosis if the ABI was measured in only 1 of the arteries. In conclusion, this study emphasizes the importance of measuring the ABI in both the posterior tibial and the anterior tibial arteries when diagnosing PAD.

- We examined whether high-sensitivity C-reactive protein (hsCRP) ≥2.0 mg/L was associated with increased intima-media thickness (IMT), plaque burden, and plaque echolucency in carotid arteries. Women (n = 635) from a population sample of 64-year-old females with varying degrees of glucose tolerance underwent risk factor assessment, measurement of hsCRP, and ultrasound examinations of the carotid arteries. Participants with hsCRP levels ≥2.0 mg/L had elevated carotid bulb IMT independently of other cardiovascular risk factors compared with those with hsCRP <2.0 mg/L. The participants with plaques in the highhsCRP group had larger total plaque area compared to those with plaque in the lower hsCRP group. Plaque echolucency did not differ between groups. High-sensitivity CRP levels ≥2.0 mg/L were accompanied by elevated IMT in the carotid bulbs independently of other cardiovascular risk factors. Total plaque area was larger among women with plaques in the high hsCRP group versus the lower hsCRP group.

The haptoglobin 2-2 genotype is associated with carotid atherosclerosis in 64-year old women with established diabetes.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Haptoglobin polymorphism generates three common human genotypes: Hp1-1, Hp2-1 and Hp2-2. Among subjects with diabetes, Hp2-2 is associated with an elevated risk to develop cardiovascular disease. The impact of haptoglobin genotype on subclinical carotid atherosclerosis is not known. We hypothesised that Hp2-2 was associated with increased occurrence of carotid atherosclerosis in subjects with diabetes. METHODS: We studied a population-based sample of 64-year old women with diabetes (n=226), either established diabetes known before study entry (n=116) or new diabetes detected at study screening. Haptoglobin genotype was determined by PCR. Carotid atherosclerosis was assessed by ultrasound imaging. RESULTS: In the entire diabetes cohort, no differences were observed in carotid intima-media thickness (IMT) or plaque prevalence between the genotype groups. However, among those with established diabetes, Hp2-2 was associated with higher plaque prevalence and larger carotid IMT compared with the Hp2-1 and Hp1-1 genotypes. Common cardiovascular risk factors did not differ between the genotype groups. CONCLUSIONS: The Hp2-2 genotype was associated with increased occurrence of subclinical carotid atherosclerosis in 64-year old women with established diabetes. This association was not explained by traditional risk factors for cardiovascular disease. These results extend previous observations that Hp2-2 is associated with clinical cardiovascular disease in diabetes.

The lipocalins retinol-binding protein-4, lipocalin-2 and lipocalin-type prostaglandin D2-synthase correlate with markers of inflammatory activity, alcohol intake and blood lipids, but not with insulin sensitivity in metabolically healthy 58-year-old Swedish men

Tidskriftsartikel (refereegranskat)abstract
- The lipocalins retinol-binding protein (RBP)-4, lipocalin-2 and lipocalin-type prostaglandin D-synthase (L-PGDS) have been suggested to mediate obesity-associated insulin resistance and other metabolic co-morbidities. The role of lipocalins is however controversial and it is unclear whether they have a physiological role in regulation of insulin sensitivity and metabolic function in clinically healthy humans. Therefore, we examined the correlations between serum levels of RBP-4, L-PGDS and lipocalin-2 and insulin sensitivity and other metabolic parameters in non-diabetic subjects selected to display variations in insulin sensitivity. 100 clinically healthy 58-year-old Swedish men were selected by stratified sampling among 818 screened subjects to represent quintiles of varying degrees of insulin sensitivity. Insulin sensitivity was measured by the euglycaemic hyperinsulinaemic clamp method. Serum levels of lipocalins and cytokines were determined using antibody-based techniques. Serum lipids were measured by standardized laboratory methods. None of the measured lipocalins showed any correlations with insulin sensitivity. However, we found that lipocalin-2 and L-PGDS were correlated with each other, but not with RBP-4. Lipocalin-2 and L-PGDS were positively correlated with soluble TNF- receptors 1 and 2 and negatively with alcohol consumption and serum HDL. Further, lipocalin-2 was correlated with interleukin-6 whereas RBP-4 was negatively correlated with TNF-α. □These results suggest that RBP-4, lipocalin-2 and L-PGDS do not regulate insulin sensitivity in healthy men. Rather the expression levels of lipocalin-2 and L-PGDS, but not RBP-4, seemed to reflect inflammatory activity and were inversely correlated with alcohol intake and serum HDL levels.
