Low maximal oxygen uptake is associated with elevated depressive symptoms in middle-aged men.

A low level of physical activity has been associated with depression, and increased physical activity has been found to have a positive effect on mood. However, the association between maximal oxygen uptake (VO(2max)) and mood has been poorly studied. In this study VO(2max) (ml/kg per min) was measured in a sample of 1,519 men aged 46-61 years during a cycle ergometer test by using respiratory gas exchange. Men with a history of psychiatric disorder or serious physical illness were excluded. Depressive symptoms were assessed using the 18-item Human Population Laboratory Depression Scale (HPL). Those who scored 5 or more in the HPL were considered to have elevated depressive symptoms. The participants were classified into quartiles according to the VO(2max). Those in the lowest quartile had a more than 3-fold (OR: 3.42; 95% CI: 1.65-7.09; p < 0.001) higher risk of having elevated depressive symptoms compared with those in the highest quartile, even after adjusting for several confounders (OR: 3.38; 95% CI: 1.60-7.14; p < 0.001). In conclusion, low VO(2max) is associated with having elevated depressive symptoms in middle-aged men.

Increased augmentation of central blood pressure is associated with increases in carotid intima-media thickness in type 2 diabetic patients.

AIMS/HYPOTHESIS: Type 2 diabetes is associated with a two- to seven-fold increase in cardiovascular morbidity and mortality. The aim of this study was to determine the relationships between intima-media thickness (IMT), an established marker of atherosclerosis, large artery function and other determinants of cardiovascular risk in type 2 diabetic patients. METHODS: We studied 228 type 2 diabetic patients (75 women, aged 62+/-2 years [mean+/-SEM]). Carotid IMT was bilaterally measured using ultrasound technology. Applanation tonometry and pulse wave analysis were used to measure aortic systolic and diastolic blood pressures, central pressure augmentation (AG) and the augmentation index (AIx), a measure of systemic arterial stiffness. Conventional cardiovascular risk factors (lipids, HbA(1)c, smoking and diabetes duration) were also assessed. RESULTS: Women had higher AG and AIx (p<0.0001), despite comparable systolic BP and heart rate in women and men. In women, AG (r=0.39, p<0.001), age (r=0.32, p<0.01), brachial systolic BP (r=0.34, p<0.01) and aortic systolic BP (r=0.34, p<0.01) correlated with IMT. In men, age (r=0.41, p<0.001), diabetes duration (r=0.25, p<0.01), AG (r=0.22, p<0.01), aortic systolic BP (r=0.21, p<0.01), brachial systolic BP (r=0.21, p<0.01) and body weight (r=0.16, p<0.05) correlated with IMT. In multiple linear regression analyses, AG and aortic systolic BP, but not brachial systolic BP, were age-independent determinants of IMT in men and women. In all patients, increased AG (adjusted for sex, age and heart rate) correlated with longer duration of diabetes, urinary albumin excretion and IMT. CONCLUSIONS/INTERPRETATION: Measures of central systolic pressure correlate with carotid IMT, independently of age and other risk markers.

C-reactive protein and the development of the metabolic syndrome and diabetes in middle-aged men.

AIMS/HYPOTHESIS: Low-grade inflammation has been implicated in the development of Type 2 diabetes and cardiovascular disease, but its role in the pathogenesis of the metabolic syndrome is unclear. We investigated the association between C-reactive protein (CRP) levels and the development of the metabolic syndrome and diabetes in men. METHODS: Serum CRP concentrations and factors related to insulin resistance were determined in middle-aged Finnish men who participated in a population-based cohort study and were free of diabetes at baseline. RESULTS: At the 11-year follow-up, 143 of 680 men had developed the metabolic syndrome as defined by the National Cholesterol Education Program (NCEP) and 103 of 598 men had developed the metabolic syndrome as defined by the World Health Organization (WHO). Our analyses excluded men with the metabolic syndrome by the respective definition at baseline. In all, 78 of 762 men developed diabetes over the same period. Men with CRP concentrations > or =3 mg/l had a several-fold higher age-adjusted risk of developing the metabolic syndrome (NCEP definition: odds ratio [OR]=3.2, 95% CI 1.9-5.5; WHO definition: OR=3.4, 95% CI 2.0-6.1) or diabetes (OR=4.1, 95% CI 2.1-8.0) than men whose CRP levels were <1.0 mg/l. Even after further adjustment for potentially confounding lifestyle factors and factors related to insulin resistance, the risk of diabetes (OR=2.3, 95% CI 1.0-5.1) was still increased in men with CRP concentrations > or =3 mg/l, but the association with the metabolic syndrome was no longer significant. CONCLUSIONS/INTERPRETATION: Low-grade inflammation may increase the risk of the metabolic syndrome and diabetes in middle-aged men, but some of the risk is mediated through obesity and factors related to insulin resistance.

Association of exercise-induced, silent ST-segment depression with the risk of stroke and cardiovascular diseases in men.

BACKGROUND AND PURPOSE: There are few if any data on the prognostic importance of silent myocardial ischemia during exercise with regard to the risk of stroke and cardiovascular diseases (CVDs) among asymptomatic men. In this prospective study, we investigated the relation of silent myocardial ischemia and the risk of stroke and CVD death in men with and without conventional risk factors. METHODS: The study sample included 1726 middle-aged men with no history of stroke, coronary heart disease, or atrial fibrillation at baseline. Silent myocardial ischemia was defined as a horizontal or downsloping ST-segment depression (>or=1 mm) during exercise electrocardiography. A total of 86 CVD-related deaths and 78 strokes occurred during an average follow-up of 10 years. RESULTS: Men with silent ischemia during exercise had a 3.5-fold increased risk of CVD death and a 2.2-fold increased risk of stroke compared with men without silent ischemia, after adjusting for conventional risk factors. Silent ischemia during exercise was associated with a 3.8-fold (95% confidence interval [CI], 1.5 to 9.5) increased risk for CVD in smokers, a 3.9-fold (95% CI, 2.1 to 7.3) increased risk in hypercholesterolemic subjects, a 3.6-fold (95% CI, 1.9 to 6.8) increased risk in the hypertensives, and 3.8-fold (95% CI, 2.0 to 7.1) increased risk in overweight men. The respective relative risks for stroke were 3.8 (95% CI, 1.1 to 12.5), 3.5 (95% CI, 1.7 to 7.4), 3.4 (95% CI, 1.6 to 7.1), and 2.9 (95% CI, 1.4 to 6.1). CONCLUSIONS: Exercise-induced silent myocardial ischemia is an important indicator of increased risk of stroke and CVD in men with other risk factors, such as smoking, hypercholesterolemia, hypertension, and being overweight.

Low HDL cholesterol concentration is associated with increased intima-media thickness independent of arterial stiffness in healthy subjects from families with low HDL cholesterol.

BACKGROUND: Low high-density lipoprotein cholesterol (HDL-C) is associated with increased risk for developing coronary artery disease. Cardiovascular disease is characterized by increased intima-media thickness (IMT) and arterial stiffness, but the effect of low HDL on these measurements has not been reported. MATERIALS AND METHODS: We studied 18 apparently healthy subjects from families with low HDL-C and 18 control subjects, which were pair-matched to maximize statistical power. Intima-media thickness was assessed using ultrasound examination of the carotid arteries. Arterial stiffness was measured using applanation tonometry on the radial artery and pulse-wave analysis to obtain central aortic pulse-pressure waveform, from which the augmentation index, a measure of global large artery stiffness, was calculated. RESULTS: Low HDL subjects (age 41 +/- 3 years, BMI 26.6 +/- 1.0 kg m(-2) had significantly lower HDL-C than the control subjects (age 41 +/- 3 years, BMI 26.5 +/- 1.0 kg m-2; 1.00 +/- 0.05 vs. 1.49 +/- 0.09 mmol L-1, low HDL vs. control subjects, P < 0.0001). Subjects with low HDL-C had significantly thicker mean IMTs than the control subjects (0.77 +/- 0.03 vs. 0.70 +/- 0.02 mm, low HDL vs. control subjects, P < 0.01). The maximal (0.99 +/- 0.04 vs. 0.89 +/- 0.03 mm, P < 0.01), far wall (0.76 +/- 0.04 vs. 0.69 +/- 0.02 mm, P < 0.05) and carotid bulb (1.11 +/- 0.06 vs. 0.97 +/- 0.04 mm) IMTs were also significantly increased, whereas the mean common carotid and the internal artery IMT were not. The age-related increase in mean IMT was more pronounced in the low HDL subjects than the control subjects (P < 0.01 for difference between elevations of age vs. IMT slopes). There were no differences in central pressure augmentation, the augmentation index, peripheral or central blood pressures between the groups. CONCLUSIONS: A low HDL-C concentration is associated with thickening of carotid IMT independent of other risk factors in healthy affected members of low HDL families.

Phloem fortification in rye bread elevates serum enterolactone level.

OBJECTIVE: To analyse the lignan content of phloem powder enriched rye bread and to study the dose-response relationship of the effect of dietary plant lignans derived from phloem on intestinal production of enterolactone by measuring enterolactone concentration in serum. DESIGN: A randomized double-blind supplementation trial. SUBJECTS: Seventy-five non-smoking men recruited by newspaper advertisements. INTERVENTION: Subjects were randomized to three study groups receiving either rye bread high in phloem (HP, 14% of rye flour substituted with phloem powder), rye bread low in phloem (LP, 7% of rye flour substituted with phloem powder) or placebo rye bread. Participants consumed 70 g of study bread daily for 4 weeks and provided serum samples for enterolactone analysis at baseline and at the end of the intervention. RESULTS: There was a significant increase in serum enterolactone concentration in the LP and HP groups compared with the placebo group (P=0.009 and P=0.003, respectively). Considerable interindividual differences were observed in the response to dietary lignans within the study groups. CONCLUSIONS: Our results indicate that plant lignans attached to insoluble fibre layer in phloem can be further metabolized and converted to enterolactone presumably by the bacteria present in the colon. Phloem powder is useful source of lignans for functional foods aimed to elevate serum enterolactone levels. SPONSORSHIP: Phloem powder and the study breads were provided by Finnpettu Oy and Linkosuo Oy, respectively. The clinical study work was sponsored in part by Oy Jurilab Ltd.

Exhaustive exercise increases plasma/serum total oxidation resistance in moderately trained men and women, whereas their VLDL + LDL lipoprotein fraction is more susceptible to oxidation.

The purpose of this study was to evaluate the effects of exhaustive exercise (marathon run) on different lipid peroxidation measurements, including copper-induced serum lipids and VLDL + LDL oxidation susceptibility, and on plasma total antioxidative capacity (TRAP), muscular damage and plasma antioxidants in healthy moderately trained male (n = 21) and female (n = 25) volunteers. Blood samples were taken before and just after the 42-km run. In women, baseline levels of several antioxidative compounds (serum albumin and uric acid, plasma free thiols and blood glutathione) were lower, resulting in 21.5% lower plasma total antioxidative capacity and 70.3% higher serum oxidation susceptibility, compared to men. To compare effects in men and women, the exercise-induced variable changes were adjusted for their baseline levels. After this adjustment, there were no statistically significant differences between the genders in the extent of muscular damage (serum creatine kinase, (CK)), or in the change in serum lipids or VLDL + LDL oxidation susceptibility, or that of plasma antioxidative capacity. A possible beneficial effect of exercise was that serum HDL cholesterol levels increased significantly in both genders, but especially in women. In the group of pooled genders (n=46), the increases in serum CK and in plasma lactate were 190% (95% CI, 133% to 246%) and 109% (95% CI, 65% to 175%), respectively. On the basis of our lipid peroxidation and TRAP measurements, uric acid was observed to be the most important plasma antioxidant. The effect of exercise was to decrease the oxidation susceptibility of serum lipids by 24.8% (95% CI 13.4% to 36.2%) and to elevate plasma TRAP by 14.6% (95% CI, 11.4% to 17.7%). Nonetheless, the oxidation susceptibility of the VLDL + LDL fraction increased by 11.0% (95% CI, 1.9% to 20.2%). Our results suggest that there are no gender-based differences in exhaustive exercise-induced lipid peroxidation or muscular damage. Secondly, even though exhaustive exercise can increase plasma/serum total resistance towards oxidation, the oxidation resistance of the atherogenic lipoprotein fraction might be diminished. On the basis of these results, several in vitro measurements of lipid peroxidation assessing both water and lipid soluble plasma fractions are needed if a true perspective of the plasma redox status is to be obtained.

A fetus suggesting an extension of theXK-aprosencephaly spectrum phenotype.

We report a fetus with atelencephaly, bilateral radial aplasia/hypoplasia, ventriculoseptal defect and megacolon, this combination of anomalies being consistent with the diagnosis of XK-aprosencephaly syndrome. The facial dysmorphology of this fetus differs from that previously reported and together with reports on overlapping phenotypes suggests an extension of the XK-aprosencephaly spectrum.

Cardiovascular fitness as a predictor of mortality in men.

OBJECTIVE: To examine the relations of cardiorespiratory fitness, as measured by maximal oxygen uptake and exercise test duration at the initiation of the study, with overall, cardiovascular disease (CVD)-related, and non-CVD-related mortality. METHODS: A population-based cohort study of 1294 men with no CVD, pulmonary disease, or cancer at baseline in Kuopio and surrounding communities in eastern Finland. During an average follow-up of 10.7 years, there were 124 overall, 42 CVD-related, and 82 non-CVD-related deaths. RESULTS: The relative risk of overall death in unfit men (maximal oxygen uptake <27.6 mL/kg per minute) was 2.76 (95% confidence interval, 1.43-5.33) (P =.002), and the relative risk of CVD-related death was 3.09 (95% confidence interval, 1.10-9.56) (P =.05), compared with fit men (maximal oxygen uptake >37.1 mL/kg per minute) after adjusting for age, examination years, smoking, and alcohol consumption. The relative risk of non-CVD-related death in unfit men was almost the same magnitude as for overall death. Furthermore, adjustment for serum lipid levels, blood pressure, plasma fibrinogen level, diabetes, and fasting serum insulin level did not weaken these associations significantly. Exercise test duration also had a strong inverse relation to overall, CVD-related, and non-CVD-related mortality. Poor cardiorespiratory fitness was comparable with elevated systolic blood pressure, smoking, obesity, and diabetes in importance as a risk factor for mortality. CONCLUSIONS: Cardiorespiratory fitness had a strong, graded, inverse association with overall, CVD-related, and non-CVD-related mortality. Maximal oxygen uptake and exercise test duration represent the strongest predictors of mortality.

Abdominal obesity is associated with accelerated progression of carotid atherosclerosis in men.

Abdominal obesity increases the risk of clinical atherosclerotic diseases, but whether it accelerates the progression of preclinical atherosclerosis is unknown. We studied whether waist-to-hip ratio (WHR) and waist circumference are associated with 4-year increase in indicators of common carotid atherosclerosis, assessed by B-mode ultrasonography, in 774 Finnish men aged 42-60 years without atherosclerotic diseases. Men with WHR of <0.91, 0.91-0.96 and >0.96 (thirds) had increase in maximal intima-media thickness (IMT) of 0.230, 0.255 and 0.281 mm/4 years (P=0.007 for linear trend; P=0.025 for difference) and plaque height of 0.241, 0.254 and 0.291 mm/4 years (P=0.005, P=0.013) adjusting for age, body mass index and technical covariates. Men with waist circumference of <85, 85-93 and >93 cm (thirds) had increase in maximal IMT of 0.227, 0.251 and 0.290 mm/4 years (P=0.011, P=0.035) and plaque height of 0.229, 0.263 and 0.296 mm/4 years (P=0.003, P=0.013). These associations were stronger in men with high (> or =3.8 mmol/l) than lower serum LDL cholesterol (P<0.05 for interaction). This is the first documentation that abdominal obesity is associated with accelerated progression of atherosclerosis, and supports the view that it is an important cardiovascular risk factor. This study emphasizes the role of avoiding abdominal obesity to prevent atherosclerotic diseases.

Cardiorespiratory fitness and the progression of carotid atherosclerosis in middle-aged men.

BACKGROUND: Good cardiorespiratory fitness has been associated with reduced risk for clinical events of atherosclerotic vascular diseases, but whether it is related to slower progression of early atherosclerosis is unclear. OBJECTIVE: To study the association between cardiorespiratory fitness and the progression of early carotid atherosclerosis. DESIGN: 4-year follow-up study. SETTING: Eastem Finland. PARTICIPANTS: Population-based sample of 854 men 42 to 60 years of age. MEASUREMENTS: Maximal oxygen uptake (VO2max [mL/kg per minute]) was measured directly by using respiratory gas exchange in a cycle ergometer exercise test. Carotid atherosclerosis was assessed by using B-mode ultrasonography. RESULTS: After adjustments for age, technical covariates, and cigarette smoking, VO2max had strong, inverse, and graded associations with 4-year increases in maximal intima-media thickness (IMT) (standardized regression coefficient beta = -0.120; P = 0.002), plaque height (beta = -0.140; P < 0.001), surface roughness (beta = -0.147; P < 0.001), and mean IMT (beta = -0.080; P = 0.035). These associations weakened but remained statistically significant after additional adjustment for systolic blood pressure, serum levels of apolipoprotein B, diabetes, and plasma fibrinogen levels. The increases in maximal IMT, surface roughness, and mean IMT (23%, 31%, and 100%, respectively) were larger among men in the lowest quartile of VO2max (<26.1 mL/kg per minute) than among those in the highest quartile (>36.2 mL/kg per minute). CONCLUSIONS: Good cardiorespiratory fitness is associated with slower progression of early atherosclerosis in middle-aged men. These findings are important because they emphasize that middle-aged men can be evaluated for cardiorespiratory fitness to estimate their future risk for atherosclerotic vascular diseases. Additional research is warranted to investigate a possible causal relationship between cardiorespiratory fitness and atherosclerosis.

Leucine7 to proline7 polymorphism in the preproneuropeptide Y is associated with the progression of carotid atherosclerosis, blood pressure and serum lipids in Finnish men.

A rather common leucine7-to-proline7 (Leu7Pro) polymorphism in the preproneuropeptide Y (prepro-NPY) gene signal peptide may be important in blood pressure regulation, cholesterol metabolism and the pathogenesis of atherosclerosis in humans. We examined the associations of the Leu7Pro polymorphism with carotid atherosclerotic progression, blood pressure and serum lipids in a population-based sample of 966 men aged 42-60 years in Finland. The Pro7 substitution (carrier frequency 12.2%) was associated with accelerated four-year increase in the mean (P=0.01) and maximal (P=0.007) common carotid intima-media thickness (IMT) and with slightly increased systolic (P=0.03) and diastolic (P=0.02) blood pressures, adjusted for other major risk factors. Men with Pro7 substitution had 30.6% (95% CI 6.9-54.0%) greater increase in the mean IMT and 20.0% (95% CI 5.3-34.4%) greater increase in the maximal IMT than men with Leu7/Leu7 genotype. The Pro7 substitution was also related to increased serum total cholesterol (P=0.01) and LDL cholesterol (P=0.02) in obese (body mass index (BMI)>30 kg/m(2)) men. This study provides important evidence suggesting that the Pro7 substitution in the prepro-NPY is an important risk factor for accelerated atherosclerotic progression, increased blood pressure and increased serum cholesterol in humans.

Effect of encapsulation on absorption of sumatriptan tablets: data from healthy volunteers and patients during a migraine.

BACKGROUND: Some comparative trials of selective serotonin 1B/ID-agonists in migraine have reported -15% lower efficacy for sumatriptan tablets than that reported in placebo-controlled trials. OBJECTIVE: This study was designed to test the hypothesis that the encapsulation methods used to mask active drug may delay absorption of sumatriptan from dosing to 2 hours after dosing (the traditional end point in clinical trials of migraine treatment), an effect that may be enhanced by migraine-associated gastric stasis. METHODS: Two randomized, open-label, 2-way crossover trials were conducted to evaluate the absorption and bioequivalence of conventional 50-mg sumatriptan tablets and encapsulated 50-mg sumatriptan tablets in supine, fasted, healthy volunteers (Glaxo Wellcome protocol SUM40270) and supine patients experiencing a migraine (Glaxo Wellcome protocol SUM40268). Absorption was assessed by calculating the area under the plasma concentration-time curve from dosing to 2 hours after dosing (AUC2) and the times to first measurable plasma concentration, 10 ng/mL, 20 ng/mL, and maximum plasma concentration. Data for the AUC from time zero to infinity and maximum plasma concentration were used to assess standard bioequivalence, which is considered to occur when the 90% CIs for the geometric mean treatment ratios (test/reference) fall between 0.8 and 1.25. RESULTS: Study 1 included 26 healthy subjects (73% men, 27% women; mean age, 39.1 years), and study 2 included 30 patients with migraine (67% women, 33% men; mean age, 42.7 years). Sumatriptan absorption was delayed with the encapsulated tablet compared with the conventional tablet 0 to 2 hours after dosing, particularly during a migraine. AUC2 values with encapsulated sumatriptan compared with the conventional tablet were 21% lower in healthy volunteers (ratio of capsule/tablet, 0.79; 90% CI, 0.588-1.050) and 27% lower in patients experiencing a migraine (ratio of capsule/tablet, 0.73; 90% CI, 0.519-1.023). Standard bioequivalence was demonstrated in both healthy volunteers and patients experiencing a migraine. CONCLUSIONS: Encapsulation delayed absorption of sumatriptan 0 to 2 hours after dosing, particularly during a migraine. This delay in absorption of the encapsulated form may account for the lower efficacy of sumatriptan in some comparative studies.

An insertion/deletion polymorphism in the alpha2B-adrenergic receptor gene is a novel genetic risk factor for acute coronary events.

OBJECTIVES: Our aim was to study whether an insertion/deletion (I/D) polymorphism in the alpha2B-adrenoceptor gene is associated with the risk for cardiovascular diseases. BACKGROUND: alpha2-adrenoceptors mediate contraction of vascular smooth muscle and induce coronary vasoconstriction in humans. The alpha2-adrenoceptor subtype B mediates vasoconstriction in mice. A variant of the human alpha2B-adrenoceptor gene that encodes a D of three residues in an intracellular acidic motif has been shown to confer decreased receptor desensitization. This receptor variant could, therefore, be involved in diseases associated with enhanced vasoconstriction. METHODS: This study was part of a prospective population-based study investigating risk factors for cardiovascular diseases in a cohort of middle-aged men from eastern Finland. Nine hundred twelve men aged 46 to 64 years were followed for an average time of 4.5 years. RESULTS: In this study population, 192 men (21%) had the D/D genotype; 256 (28%) had the I/I genotype, and 464 (51%) had a heterozygous genotype. In a Cox model adjusting for other coronary risk factors, men with the D/D genotype had 2.2 times (95% confidence interval: 1.1 to 4.4, p = 0.02) the risk to experience an acute coronary event (n = 15 for D/D, 10 for I/I and 12 for I/D) compared with men carrying either of the other two genotypes. The alpha2B-adrenoceptor genotype was not associated with hypertension in this study population. CONCLUSIONS: The D/D genotype of the alpha2B-adrenoceptor is a novel genetic risk factor for acute coronary events, but not for hypertension.

Exercise-induced silent myocardial ischemia and coronary morbidity and mortality in middle-aged men.

OBJECTIVES: We investigated the prognostic significance of exercise-induced silent myocardial ischemia in both high and low risk men with no prior coronary heart disease (CHD). BACKGROUND: Silent ischemia predicts future coronary events in patients with CHD, but there is little evidence of its prognostic significance in subjects free of CHD. METHODS: We investigated the association of silent ischemia, as defined by ST depression during and after maximal symptom-limited exercise test, with coronary risk in a population-based sample of men with no prior CHD followed for 10 years on average. RESULTS: Silent ischemia during exercise was associated with a 5.9-fold (95% CI 2.3 to 11.8) CHD mortality in smokers, 3.8-fold (95% CI 1.9 to 7.9) in hypercholesterolemic men and 4.7-fold (95% CI 2.4 to 9.1) in hypertensive men adjusting for other risk factors. The respective relative risks (RRs) of any acute coronary event were 3.0 (95% CI 1.7 to 5.1), 1.9 (95% CI 1.2 to 3.1) and 2.2 (95% CI 1.4 to 3.5). These associations were weaker in men without these risk factors. Furthermore, silent ischemia after exercise was a stronger predictor for the risk of acute coronary events and CHD death in smokers and in hypercholesterolemic and hypertensive men than in men without risk factors. CONCLUSIONS: Exercise-induced silent myocardial ischemia was a strong predictor of CHD in men with any conventional risk factor, emphasizing the importance of exercise testing to identify asymptomatic high risk men who could benefit from risk reduction and preventive measures.
