Adv Nutr 2023; 14:1633-1643. [PMID: 37758058 PMCID: PMC10721517 DOI: 10.1016/j.advnut.2023.09.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 09/09/2023] [Accepted: 09/21/2023] [Indexed: 10/03/2023] Open
Abstract
The effects of isoflavones on postmenopausal female's blood lipid profile have yielded conflicting results in previous studies. Further investigation is necessary to determine the potential benefits of isoflavone therapy in managing cardiovascular health in this population. This meta-analysis aimed to assess the effects of isoflavones on blood lipid concentrations in postmenopausal females. A comprehensive search was conducted in major databases for randomized controlled trials published between 2000 and 2023. Eighteen studies were included in the analysis, which examined the impact of isoflavone intake on blood lipids in postmenopausal females. Isoflavone consumption resulted in a significant reduction in triacylglycerol (TG) concentrations (-12.50 mg/dL; 95% CI: -23.09, -1.91) and a modest increase in high-density lipoprotein cholesterol (HDL cholesterol) concentrations (1.83 mg/dL; 95% CI: 0.03, 3.64). Subgroup analysis showed that isoflavones significantly decreased TG (-15.79 mg/dL; 95% CI: -28.36, -3.22) and increased HDL cholesterol (2.49 mg/dL; 95% CI: 1.80, 3.19) in postmenopausal females under 65 y old. No significant effects were observed in females over 65 y old. Both low (≤80 mg/d) and high (>80 mg/d) doses of isoflavones exhibited TG-lowering effects, whereas only the high dose increased HDL cholesterol. Longer treatment duration (≥24 wk) was associated with a significant reduction in TG, whereas HDL cholesterol improvement occurred during the early period (<24 wk) of supplementation. The consumption of isoflavones resulted in a significant reduction in TG concentrations and an increase in HDL cholesterol concentrations among postmenopausal females under 65 y of age.

A Fiber-Based SPR Aptasensor for the In Vitro Detection of Inflammation Biomarkers. MICROMACHINES 2022; 13:mi13071036.

Abstract
It is widely accepted that the abnormal concentrations of different inflammation biomarkers can be used for the early diagnosis of cardiovascular disease (CVD). Currently, many reported strategies, which require extra report tags or bulky detection equipment, are not portable enough for onsite inflammation biomarker detection. In this work, a fiber-based surface plasmon resonance (SPR) biosensor decorated with DNA aptamers, which were specific to two typical inflammation biomarkers, C-reactive protein (CRP) and cardiac troponin I (cTn-I), was developed. By optimizing the surface concentration of the DNA aptamer, the proposed sensor could achieve a limit of detection (LOD) of 1.7 nM (0.204 μg/mL) and 2.5 nM (57.5 ng/mL) to CRP and cTn-I, respectively. Additionally, this biosensor could also be used to detect other biomarkers by immobilizing corresponding specific DNA aptamers. Integrated with a miniaturized spectral analysis device, the proposed sensor could be applied for constructing a portable instrument to provide the point of care testing (POCT) for CVD patients.

Cardiovascular mortality and risk behaviours by degree of urbanization before, during and after the economic crisis in Spain. BMC Public Health 2019; 19:1109. [PMID: 31412835 PMCID: PMC6694539 DOI: 10.1186/s12889-019-7427-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2019] [Accepted: 07/31/2019] [Indexed: 01/20/2023] Open
Abstract
BACKGROUND To estimate the relationship of the degree of urbanization to cardiovascular mortality and to risk behaviours before, during and after the 2008 economic crisis in Spain. METHODS In three areas of residence - large urban areas, small urban areas and rural areas - we calculated the rate of premature mortality (0-74 years) from cardiovascular diseases before the crisis (2005-2007), during the crisis (2008-2010 and 2011-2013) and after the crisis (2014-2016), and the prevalence of risk behaviours in 2006, 2011 and 2016. In each period we estimated the mortality rate ratio (MRR) and the prevalence ratio, taking large urban areas as the reference. RESULTS In men, no significant differences were observed in mortality between the two urban areas, while the MRR in rural areas went from 0.92 [95% confidence interval, 0.90-0.94) in 2005-2007 to 0.94 (0.92-0.96) in 2014-2016. In women, no significant differences were observed in mortality between the rural and large urban areas, whereas the MRR in small urban areas decreased from 1.11 (1.08-1.14) in 2005-2007 to 1.06 (1.02-1.09) in 2014-2016. The rural areas had the lowest prevalence of smoking, obesity and physical inactivity in men, and of obesity in women. No significant differences were observed in smoking or physical inactivity by area of residence in women. CONCLUSION The pattern of cardiovascular mortality by degree of urbanization was similar before and after the crisis, although in women the excess mortality in small urban areas with respect to large urban areas was smaller after the crisis. The different pattern of risk behaviours in men and women, according to area of residence, could explain these findings.

Abstract
There is clear and consistent evidence that regular physical activity is an important component of healthy lifestyles and fundamental to promoting health and preventing disease. Despite the known benefits of physical activity participation, many people in the United States remain inactive. More specifically, physical activity behavior is socially patterned with lower participation rates among women; racial/ethnic minorities; sexual minority youth; individuals with less education; persons with physical, mental, and cognitive disabilities; individuals >65 yr of age; and those living in the southeast region of the United States. Many health-related outcomes follow a pattern that is similar to physical activity participation. In response to the problem of inequities in physical activity and overall health in the United States, the American College of Sports Medicine (ACSM) has developed a national roadmap that supports achieving health equity through a physically active lifestyle. The actionable, integrated pathways that provide the foundation of ACSM's roadmap include the following: 1) communication-raising awareness of the issue and magnitude of health inequities and conveying the power of physical activity in promoting health equity; 2) education-developing educational resources to improve cultural competency for health care providers and fitness professionals as well as developing new community-based programs for lay health workers; 3) collaboration-building partnerships and programs that integrate existing infrastructures and leverage institutional knowledge, reach, and voices of public, private, and community organizations; and 4) evaluation-ensuring that ACSM attains measurable progress in reducing physical activity disparities to promote health equity. This article provides a conceptual overview of these four pathways of ACSM's roadmap, an understanding of the challenges and advantages of implementing these components, and the organizational and economic benefits of achieving health equity.

Abstract
BACKGROUND Despite the progress made to decrease risk factors for cardiovascular diseases, disparities still exist. We examined how education and ethnicity interact to determine disparities in cardiovascular health (CVH) as defined by the American Heart Association. HYPOTHESIS Education modifies the effect of ethnicity on CVH. METHODS Individual CVH metrics (smoking, physical activity, body mass index, diet, total cholesterol, blood pressure, and blood glucose) were defined as ideal, intermediate, or poor. Combined scores were categorized as inadequate, average, or optimal CVH. Education was categorized as postgraduate, college, some college, and high school or less; ethnicity was categorized as white, Hispanic, black, and other. Main and interactive associations between education, ethnicity, and the measures of CVH were calculated with multinomial logistic regression. RESULTS Of 9056 study participants, 74% were women, and mean age was 43 (±12) years. Over half were Hispanic, and two-thirds had at least a college education. With postgraduate education category as the reference, participants with less than a college education were less likely to achieve ideal status for most of the individual CVH metrics, and also less likely to achieve 6 to 7 ideal metrics, and optimal CVH scores. In most of the educational categories, Hispanic participants had the highest proportion with optimal CVH scores and 6 to 7 ideal metrics, whereas black participants had the lowest proportion. However, there were no statistically significant interactions of education and ethnicity for ideal CVH measures. CONCLUSIONS Higher educational attainment had variable associations with achieved levels of ideal CVH across race/ethnic groups. Interventions to improve CVH should be tailored to meet the needs of target communities.

Abstract
Metabolic syndrome (MS), high-sensitivity C-reactive protein (hs-CRP), and chronic kidney disease (CKD) are related to cardiovascular diseases. Although MS is common in CKD subjects, the contribution of MS-associated risk factors and hs-CRP to arterial stiffness in CKD has not been well studied.In this cross-sectional cohort study, we enrolled 9903 subjects who underwent brachial-ankle pulse wave velocity (baPWV) measurements from our database of Health Care Center. CKD was defined as an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m. Comparing those grouped with and without CKD, multivariate linear regression analyses were used.Overall, baPWV was found to have an inverse relationship with eGFR (P for trend <0.001), which increased progressively with the presence of CKD, increasing number of MS-associated risk factors and hs-CRP (P for trend <0.001). In the non-CKD group, age, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glucose, triglyceride, high-density lipoprotein cholesterol, and hs-CRP independently predicted baPWV, whereas in CKD, eGFR, age, gender, body mass index, SBP, DBP, and fasting glucose remained predictors.The number of MS-associated risk factors and hs-CRP remains a determinant of arterial stiffness in both CKD and non-CKD groups. The decline of renal function contributes to arterial stiffness only in CKD but not in non-CKD. Our findings suggest that for CKD subjects, renal function, BP, and glycemic control are potential targets for further interventional studies of arterial stiffness.

Abstract
Using historical data from 1,763 birth cohorts from 1800 to 1935 in 13 developed countries, we show that what is now seen as normal-a large excess of female life expectancy in adulthood-is a demographic phenomenon that emerged among people born in the late 1800s. We show that excess adult male mortality is clearly rooted in specific age groups, 50-70, and that the sex asymmetry emerged in cohorts born after 1880 when male:female mortality ratios increased by as much as 50% from a baseline of about 1.1. Heart disease is the main condition associated with increased excess male mortality for those born after 1900. We further show that smoking-attributable deaths account for about 30% of excess male mortality at ages 50-70 for cohorts born in 1900-1935. However, after accounting for smoking, substantial excess male mortality at ages 50-70 remained, particularly from cardiovascular disease. The greater male vulnerability to cardiovascular conditions emerged with the reduction in infectious mortality and changes in health-related behaviors.

Abstract
BACKGROUND The link between environmental estrogen exposure and defects in the female reproductive tract is well established. The phytoestrogen genistein is able to modulate uterine estrogen receptor (ER) activity, and dietary exposure is associated with uterine pathologies. Regulation of stress and immune functions by the glucocorticoid receptor (GR) is also an integral part of maintaining reproductive tract function; disruption of GR signaling by genistein may also have a role in the adverse effects of genistein. OBJECTIVE We evaluated the transcriptional response to genistein in Ishikawa cells and investigated the effects of genistein on GR-mediated target genes. METHODS We used Ishikawa cells as a model system to identify novel targets of genistein and the synthetic glucocorticoid dexamethasone through whole genome microarray analysis. Common gene targets were defined and response patterns verified by quantitative real-time reverse-transcription polymerase chain reaction. The mechanism of transcriptional antagonism was determined for select genes. RESULTS Genistein regulated numerous genes in Ishikawa cells independently of estradiol, and the response to coadministration of genistein and dexamethasone was unique compared with the response to either estradiol or dexamethasone alone. Furthermore, genistein altered glucocorticoid regulation of GR target genes. In a select set of genes, co-regulation by dexamethasone and genistein was found to require both GR and ERα signaling, respectively. CONCLUSIONS Using Ishikawa cells, we observed that exposure to genistein resulted in distinct changes in gene expression and unique differences in the GR transcriptome.

Abstract
South Asian countries have developed infectious disease control programs such as routine immunization, vaccination, and the provision of essential drugs which are operating nationwide in cooperation with many local and foreign NGOs. Most South Asian countries have a relatively low prevalence of HIV/AIDS until now, but issues like poverty, food insecurity, illiteracy, poor sanitation, and social stigma around AIDS are widespread and are creating formidable challenges to prevention of further spread of this epidemic. Besides that, resurgence of tuberculosis along with the emergence of the drug resistant (MDR-TB and XDRTB) strains and the coepidemic of TB and HIV are posing ever-growing threats to the underdeveloped healthcare infrastructure. The countries are undergoing an epidemiological transition where the disease burden is gradually shifting to noncommunicable diseases, but the infectious diseases still account for almost half of the total disease burden. Despite this huge burden of infectious diseases in South Asia, which is second only to Africa, there is yet any study on the social determinants of infectious diseases in a local context. This paper examines various issues surrounding the social determinants of infectious diseases in South Asian countries with a special reference to HIV and tuberculosis. And, by doing so, it attempts to provide a framework for formulating more efficient prevention and intervention strategies for the future.

Abstract
BACKGROUND AND AIM The associations between soy food consumption, cardiometabolic disturbances and subclinical atherosclerosis remain controversial due to limited evidence. We examined the associations of habitual soy food consumption with cardiometabolic disturbances and carotid intima-media thickness (CIMT). METHODS AND RESULTS We included 2939 subjects (2135 women and 804 men) aged 50-75 years in this community-based cross-sectional study. Dietary data and other covariates were collected using interviewer-administered questionnaires. We determined CIMT in relation to each subject's common carotid artery, internal carotid artery, carotid bifurcation, blood lipids, glucose and urine acid, blood pressure and waist circumference. A logistic regression model was applied to estimate the odd ratios (ORs) and 95% confidence intervals (CIs), and linear regression was used to estimate the regression coefficient and 95% CIs. After adjusting for potential confounders, we found that greater consumption of soy protein (6.1 vs. 0.5 g/d) was inverse associated with the presence of elevated total cholesterol (TC), dyslipidemia, abdominal obesity and hyperuricemia in women, and with abdominal obesity in men, although no significant sex-soy interactions were observed (P: 0.145-0.985). The consumption of soy protein and isoflavones was inversely associated with the number of cardiometabolic disturbances among women, but not men. There were no significant associations of soy protein and isoflavones with CIMT thickening and other cardiometabolic disturbances. CONCLUSION Greater soy consumption was associated with a lower presence of elevated TC, dyslipidemia, hyperuricemia and less number of cardiometabolic disturbances components in women.

Abstract
Meju, a naturally fermented soy block used to produce soy paste and soy sauce in Korea, is suggested to exhibit hypolipidemic and antiinflammatory activities; however, its mechanisms of action are elusive. Here, we report that the water-soluble fibers but not the amino acids and peptides from meju exhibited hypolipidemic activity in vivo. Feeding of fermented soybean fibers (FSF) from meju reduced plasma cholesterol, triglyceride, adipocyte size, and hepatic lipid accumulation in C57BL/6 J mice. FSF treatment reduced HMG-CoA reductase expression, whereas the expression of genes in the fatty acid uptake and subsequent beta-oxidation were significantly induced in the livers. Hepatic lipogenic genes, including Srebp1c and Lxrα, were unaltered. Feeding with the fermented soybean peptides and amino acids (FSPA) induced the expression of lipogenic genes, which may have canceled the induction of low-density lipoprotein receptor and Cyp7a1 gene expressions in FSPA livers. The plasma concentrations of C-reactive protein, TNF-α, and interlukin-6 were significantly reduced in the FSF, FSPA, and meju groups compared with the control groups, suggesting that both of the fibers and peptides/amino acids from meju may be beneficial. These findings suggest that soluble fibers from meju are critical hypolipidemic components that regulate hepatic gene expressions and reduce proinflammatory cytokines in vivo.

Abstract
BACKGROUND Genetic analysis has been successful in identifying causative mutations for individual cardiovascular risk factors. Success has been more limited in mapping susceptibility genes for clusters of cardiovascular risk traits, such as those in the metabolic syndrome. METHODS We identified three large families with coinheritance of early-onset coronary artery disease, central obesity, hypertension, and diabetes. We used linkage analysis and whole-exome sequencing to identify the disease-causing gene. RESULTS A founder mutation was identified in DYRK1B, substituting cysteine for arginine at position 102 in the highly conserved kinase-like domain. The mutation precisely cosegregated with the clinical syndrome in all the affected family members and was absent in unaffected family members and unrelated controls. Functional characterization of the disease gene revealed that nonmutant protein encoded by DYRK1B inhibits the SHH (sonic hedgehog) and Wnt signaling pathways and consequently enhances adipogenesis. Furthermore, DYRK1B promoted the expression of the key gluconeogenic enzyme glucose-6-phosphatase. The R102C allele showed gain-of-function activities by potentiating these effects. A second mutation, substituting proline for histidine 90, was found to cosegregate with a similar clinical syndrome in an ethnically distinct family. CONCLUSIONS These findings indicate a role for DYRK1B in adipogenesis and glucose homeostasis and associate its altered function with an inherited form of the metabolic syndrome.

Abstract
In this study, we challenged to identify vasoactive peptides in soybean 11S glycinin hydrolysate by thermolysin to regulate intracellular Ca(2+) concentration ([Ca(2+)]i) that can induce constrictive vascular tension. As a function of the inhibition of elevated [Ca(2+)]i by 10 μM angiotensin (Ang) II in vascular smooth muscle cells (VSMCs), eleven peptides were successfully identified from the hydrolysate, among which His-Gly-Lys exhibited the most potent inhibition against [Ca(2+)]i elevation in Ang II-stimulated VSMCs (inhibition at 300 μM: 46.5±8.0% vs. control). The biological capacity of His-Gly-Lys analogues as an [Ca(2+)]i inhibitor was also proven when His-Lys and His-Gly-Arg elicited a significant reduction in [Ca(2+)]i. In contrast, less reduction of [Ca(2+)]i by His-Gly-Ile and His-(3-methyl)-Gly-Lys indicated the importance of the imino proton in His, along with basic amino acids positioned at C-terminal for the effect.

Abstract
OBJECTIVE The objective of this analysis was to compare the costs, benefits and cost effectiveness of two dosage regimens of cerivastatin (0.2 and 0.4 mg/day) with Italian National Health Service (NHS) reimbursed comparative statins in the primary prevention of coronary heart disease in Italy. This study is part of a broader analysis undertaken in five European countries. DESIGN AND SETTING A cost-effectiveness analysis (CEA) was performed, as the interventions have the same treatment objectives but vary in terms of magnitude of effectiveness. This CEA compared alternative treatments both in the NHS and from societal perspectives. PATIENTS A coronary heart disease risk assessment model, based on intervention study data from the Lipid Research Clinics Coronary Primary Prevention Trial, was used. This was augmented with demographic, disease, life expectancy, pharmacological and economic data for patients with coronary heart disease in Italy. RESULTS In terms of average cost effectiveness, our analysis showed that cerivastatin 0.2 mg/day compared favourably with pravastatin 20 mg/day, and compared similarly with simvastatin 20 mg/day in all age groups studied. The study also demonstrated that cerivastatin 0.4 mg/day compared favourably with both simvastatin 40 mg/day and pravastatin 20 mg/day. These results were consistent for both the NHS and societal perspective.The incremental cost per life-year gained [in 1998 Italian lire (L)] of simvastatin versus cerivastatin ranged from about L40 million [or Euro (Eur)20 658] to greater than L650 million (or Eur335 697). Cerivastatin 0.2 mg/day was more cost-effective than pravastatin 20 mg/day, while the incremental cost per life-year gained for cerivastatin 0.4 mg/day versus pravastatin 20 mg/day ranged from L11.1 million (or Eur5733) to L31.8 million (or Eur16 423) in the three age groups (35 to 39 years, 50 to 54 years and 65 to 69 years) for both perspectives. CONCLUSIONS The results of this study showed that in primary prevention, average cost-effectiveness ratios of cerivastatin compared favourably with those of the other pharmacological interventions available on the Italian market.

Abstract
A number of cardioprotective effects, including the reduced oxidation of the low-density lipoprotein (LDL) particles, have been attributed to dietary soy isoflavones. Paraoxonase 1 (PON1), an enzyme mainly synthesized in the liver, may exhibit anti-atherogenic activity by protecting LDL from oxidation. Thus, dietary and pharmacological inducers of PON1 may decrease cardiovascular disease risk. Using a luciferase reporter gene assay we screened different flavonoids for their ability to induce PON1 in Huh7 hepatocytes in culture. Genistein was the most potent flavonoid with regard to its PON1-inducing activity, followed by daidzein, luteolin, isorhamnetin and quercetin. Other flavonoids such as naringenin, cyanidin, malvidin and catechin showed only little or no PON1-inducing activity. Genistein-mediated PON1 transactivation was partly inhibited by the oestrogen-receptor antagonist fulvestrant as well as by the aryl hydrocarbon receptor antagonist 7-ketocholesterol. In contrast to genistein, the conjugated genistein metabolites genistein-7-glucuronide, genistein-7-sulfate and genistein-7,4'-disulfate were only weak inducers of PON1 transactivation. Accordingly, dietary genistein supplementation (2 g/kg diet over three weeks) in growing rats did not increase hepatic PON1 mRNA and protein levels as well as plasma PON1 activity. Thus, genistein may be a PON1 inducer in cultured hepatocytes in vitro, but not in rats in vivo.

Impairment of ovarian function and associated health-related abnormalities are attributable to low social status in premenopausal monkeys and not mitigated by a high-isoflavone soy diet.

[PMID: 20956266 PMCID: PMC2989874 DOI: 10.1093/humrep/deq288] [Citation(s) in RCA: 56] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2010] [Revised: 09/03/2010] [Accepted: 09/14/2010] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Psychological stress may impair premenopausal ovarian function and contribute to risk for chronic disease. Soy isoflavones may also influence ovarian function and affect health. Here, we report the effects of a psychological stressor (subordinate social status) and dietary soy on reproductive function and related health indices in female monkeys. We hypothesized that reproductive compromise and adverse health outcomes would be induced in subordinate when compared with dominant monkeys and be mitigated by exposure to soy. METHODS Subjects were 95 adult cynomolgus monkeys (Macaca fascicularis) housed in social groups of five or six. Animals consumed a soy-free, animal protein-based diet during an 8-month Baseline phase and then, during a 32-month Treatment phase, consumed either the baseline diet or an identical diet that substituted high-isoflavone soy protein for animal protein. RESULTS Across more than 1200 menstrual cycles, subordinate monkeys consistently exhibited ovarian impairment [increased cycle length (P < 0.02) and variability (P < 0.02) and reduced levels of progesterone (P < 0.04) and estradiol (P < 0.04)]. Subordinate status was confirmed behaviorally and was associated with elevated cortisol (P < 0.04) and relative osteopenia (P < 0.05). Consumption of the soy diet had no significant effects. CONCLUSIONS (i) Psychological stress adversely affects ovarian function and related health indices in a well-accepted animal model of women's health; (ii) Similar effects may extend to women experiencing reproductive impairment of psychogenic origin; (iii) soy protein and isoflavones neither exacerbate nor mitigate the effects of an adverse psychosocial environment; and (iv) this study was limited by an inability to investigate the genetic and developmental determinants of social status.

Abstract
ABSTRACTAlthough previous research has examined the various correlates of self-rated health, little attention has been paid to how position in the social structure influences this important measure of health. Drawing upon the social structure and personality perspective, I examine whether the relationship between socio-economic status (income adequacy and education) and self-rated health is mediated by financial stress, self-esteem, mastery, social support, smoking, alcohol consumption and physical activity, using data from the 1994 National Population Health Survey. Results show that almost one-third of the relationship can be explained by the mediating effect of these variables. Income adequacy and education, however, remain significantly related to self-rated health net of these variables. Further research with a broader array of variables related to social position is required to specify the mechanisms connecting socio-economic status and perceived health.

Abstract
BACKGROUND AND AIM It has been argued that cardiovascular disease (CVD) is not very prevalent in developing countries, particularly in a rural community. This study examined the prevalence of CVD risk of a semirural community in Malaysia through an epidemiological survey. METHODS Subjects were invited to a free health screening service carried out over a period of 6 weeks. Then, a follow-up study of the initial nonresponders was done in the villages that showed a poorer response. The survey was conducted using a standardized questionnaire. Hypertension was defined as blood pressure > or =140/90 mm Hg. The Framingham Coronary Disease Risk Prediction Score (FRS) was used as a measure of CVD risk. RESULTS A total of 1417 subjects participated in this survey. The response rate was 56%. A follow-up survey of the nonresponders did not show any differences from the initial responders in any systematic way. The prevalence of CVD risk factors was high in both men and women. The mean (+/-SD) FRS was 9.4 (+/-2.5) and 11.3 (+/-4.1) for men and women, respectively. The mean predicted coronary heart disease (CHD) risk was high at 20% to 25% for men and medium at 11% to 13% for women. Overall, 55.8% of the men had >20% risk of having a CHD event in the next 10 years whereas women's risk was lower, with 15.1% having a risk of > or =20%. CONCLUSION The prevalence of CVD risk even in a semirural community of a developing country is high. Every effort should be made to lower these risk factors.

Abstract
Approximately one half of the recent decline observed in age-adjusted coronary heart disease (CHD) mortality rates can be attributed to the use of modern medical and surgical interventions. In 2000, however, only about 30% to 60% of eligible patients actually received the appropriate treatment. To examine the reduction in CHD mortality potentially achievable by increasing the provision of specific medical and surgical treatment to eligible patients with CHD in the United States, we integrated the data on CHD patient numbers, medical and surgical treatment uptake levels, and treatment effectiveness using a previously validated CHD policy model. We estimated the number of deaths prevented or postponed for 2000 (baseline) and for an alternative scenario (60% of eligible patients). In 2000, the treatment levels in the United States were generally poor; only 30% to 60% of eligible patients received the appropriate therapy. These treatments resulted in approximately 159,330 fewer deaths. By treating 60% of eligible patients, 297,470 fewer deaths would have been obtained (minimum 118,360; maximum 628,120), representing 134,635 less than in 2000, with approximately 32% from heart failure therapy, 30% from secondary prevention therapy, 19% from acute coronary syndrome treatment, 15% from primary prevention with statins, 0.5% from hypertension treatment, and 1% from coronary bypass surgery for chronic angina. These findings remained stable in the sensitivity analysis. In conclusion, increasing the proportion of eligible patients with CHD who received the appropriate treatment could have achieved approximately 135,000 fewer deaths in 2000, almost doubling the benefit actually achieved. Future strategies should maximize the delivery of appropriate therapies to all eligible patients with CHD and prioritize medical therapies for secondary prevention and heart failure.

Abstract
Non-prescription remedies are becoming increasingly popular particularly amongst postmenopausal who in this market are the largest consumers. Phytoestrogens are a large family of plant derived molecules possessing various degrees oestrogen like activity. Food or food supplements containing phytoestrogen are often been advocated as an alternative to hormonal replacement therapy (HRT) in women with contraindications to the use of conventional oestrogen replacement, or simply wanting a more 'natural' alternatives. There have been several studies performed with phytoestrogen in various aspects of the postmenopausal women health. Results have been sometimes conflicting and difficult to interpret. The lack of knowledge of what precisely is the active ingredient, its minimally effective doses, the lack of standardisation of the preparations used as well as the large individual variability of metabolism of precursors introduced with the diet may all have played a role in confusing the issue about effectiveness of these compounds. Phytoestrogen fall in the gray area between food and drugs hence in spite of the vast public interest, there are no interests in company producing these supplements in investing in research from which they will not exclusively benefit from. It is difficult for the physician to know how to advise patients on this matter. In this paper we critically review the clinical data available to date in an attempt to answer some of the most commonly asked questions about dose and type of phytoestrogens supplementation most likely to be effective in different aspects of climacteric woman health.

Abstract
This paper reviews the epidemiological evidence on the association of alcohol consumption with the major cardiovascular diseases (hypertension, stroke and coronary heart disease), and all causes of death. The focus is on light and moderate consumption and several important methodological issues are apparent with the epidemiological evidence on alcohol and mortality. The epidemiological data justify the following recommendations on alcohol consumption. The evidence does not support the unqualified claim that light and moderate drinking confers overall health benefits. However, in persons over 35 years of age, there is no consistent evidence that daily consumption of up to 2-3 drinks in men or up to 1-2 drinks in women increases the risk of dying. Non-drinkers should not be encouraged to change their drinking status. The consumption of more than 2-3 drinks per day in men and more than 1-2 drinks per day in women should be actively discouraged. Further research on the effects of light and moderate alcohol consumption on cardiovascular disease and all causes of death are required, particularly in young people, women and the elderly.

Abstract
This systematic review of population-based studies of the incidence and early (21 days to 1 month) case fatality of stroke is based on studies published from 1970 to 2008. Stroke incidence (incident strokes only) and case fatality from 21 days to 1 month post-stroke were analysed by four decades of study, two country income groups (high-income countries and low to middle income countries, in accordance with the World Bank's country classification) and, when possible, by stroke pathological type: ischaemic stroke, primary intracerebral haemorrhage, and subarachnoid haemorrhage. This Review shows a divergent, statistically significant trend in stroke incidence rates over the past four decades, with a 42% decrease in stroke incidence in high-income countries and a greater than 100% increase in stroke incidence in low to middle income countries. In 2000-08, the overall stroke incidence rates in low to middle income countries have, for the first time, exceeded the level of stroke incidence seen in high-income countries, by 20%. The time to decide whether or not stroke is an issue that should be on the governmental agenda in low to middle income countries has now passed. Now is the time for action.

Abstract
The effects of and responses to the health impacts of climate change will affect individuals, communities, and societies. Effectively preparing for and responding to current and projected climate change requires ongoing assessment and action, not a one-time assessment of risks and interventions. To promote resilience to climate change and other community stressors, a stepwise course of action is proposed for community-based adaptation that engages stakeholders in a proactive problem solving process to enhance social capital across local and national levels. In addition to grassroots actions undertaken at the community level, reducing vulnerability to current and projected climate change will require top-down interventions implemented by public health organizations and agencies.

Abstract
Background Plant sterols are an established non-pharmacological means to reduce total and LDL blood cholesterol concentrations and are therefore recommended for cholesterol management by worldwide-renown health care institutions. Their efficacy has been proven in many types of foods with the majority of trials conducted in spreads or dairy products. As an alternative to dairy products, soy based foods are common throughout the world. Yet, there is little evidence supporting the efficacy of plant sterols in soy-based foods. The objective of this study was to investigate the effect of a soy drink enriched with plant sterols on blood lipid profiles in moderately hypercholesterolemic subjects. Methods In a randomized, placebo-controlled double-blind mono-centric study, 50 subjects were assigned to 200 ml of soy drink either enriched with 2.6 g plant sterol esters (1.6 g/d free plant sterol equivalents) or without plant sterols (control) for 8 weeks. Subjects were instructed to maintain stable diet pattern and physical activity. Plasma concentrations of lipids were measured at initial visit, after 4 weeks and after 8 weeks. The primary measurement was the change in LDL cholesterol (LDL-C). Secondary measurements were changes in total cholesterol (TC), non-HDL cholesterol (non-HDL-C), HDL cholesterol (HDL-C) and triglycerides. Results Regular consumption of the soy drink enriched with plant sterols for 8 weeks significantly reduced LDL- C by 0.29 mmol/l or 7% compared to baseline (p < 0.05). TC and non-HDL-C concentrations decreased by 0.26 mmol/l and 0.31 mmol/l (each p < 0.05), respectively. Mean reductions in total, LDL and non-HDL cholesterol were significantly greater than in the placebo group (p < 0.05). HDL-C and triglycerides were not affected. Compliance was very high (>96%), and products were well tolerated. Conclusion Daily consumption of a plant sterol-enriched soy drink significantly decreased total, non-HDL and LDL cholesterol and is therefore an interesting and convenient aid in managing mild to moderate hypercholesterolemia.

Abstract
The European Centre for Disease Prevention and Control was founded in response to newly emerging infections such as severe acute respiratory syndrome and avian influenza. However, Europe faces other communicable disease challenges that have proven to be remarkably resilient to public health interventions. We present examples of communicable diseases with inequitable distribution among those with poor educational attainment, low income, or other socioeconomic factors in every European country. Because these findings are incompatible with social justice and fairness, we examine strategic interventions targeting upstream causes of communicable disease transmission keeping in mind 10 indispensable public health functions essential to reach marginalized groups. These interventions have to be tailored to the socio-political context and rely on community-based decision-making and intersectorial collaboration.

Abstract
Lower CVD incidence is reported in Asian populations consuming soya-containing food. As polymorphonuclear leukocytes (PMN) are involved in the risk of CVD, we investigated the modulatory effect of soya isoflavones on several PMN functions and their molecular mechanisms in vitro. PMN, isolated from blood from healthy subjects, were tested upon activation with 1 microm- n-formyl-methyl-leucyl-phenylalanine (fMLP) for superoxide anion production (ferric cytochrome c reduction) and released elastase (chromogenic test). PMN homotypic aggregates stimulated by fMLP or P-selectin in dynamic conditions were detected by optical microscopy. PMN, mixed with thrombin-activated, washed platelets, formed cell aggregates, measured by flow cytometry. Phosphorylation of Pyk2, a focal adhesion kinase, was studied by immunoprecipitation and immunoblotting with specific antibodies. Genistein, daidzein and equol inhibited superoxide anion production (IC50 0.25 (sem 0.1), 21.0 (sem 4.2) and 13.0 (sem 2.8) microm, respectively); the release of elastase was prevented by genistein (IC50 63 (sem 17) microm). PMN homotypic aggregates, stimulated by fMLP, were significantly reduced (24 (sem 12) and 51 (sem 14) % of control) by 100 microm genistein and equol. P-selectin-induced aggregates were reduced to 19 (sem 6), 44 (sem 10) and 28 (sem 9) % of control by 100 microm genistein, daidzein and equol, respectively. Genistein, daidzein and equol also significantly reduced mixed platelet-PMN aggregates (IC50 4.0 (sem 0.9), 57 (sem 6) and 66 (sem 23) microm, respectively). In PMN challenged by fMLP or P-selectin, activation of Pyk2 was prevented by isoflavones. The cardioprotective effect of soya-containing food might be linked to reduction of PMN activation and PMN-platelet interaction, novel targets for the biological effects of soya isoflavones.

Abstract
BACKGROUND The objective of this study was to compare current prevalence of major cardiovascular risk factors (CRF) between a cohort of patients affected by the toxic oil syndrome (TOS) epidemic, which occurred in Spain in 1981, and the unaffected Spanish population. METHODS This was a case-referent study covering 1276 TOS cases and a referent population of 2843 (aged 35-65 years) using data collected from 1996 to 2003. Study variables were high blood pressure, hyperglycemia, dyslipemia, obesity, and metabolic syndrome. Smoking habit, alcohol intake, family and personal history of ischemic heart disease, as well as a personal history of cerebrovascular disease were also assessed in TOS patients. RESULTS Compared to the general population, TOS patients registered a threefold rise in prevalence of diabetes, a 2.57-fold increase in hypertension, a 1.38-fold increase in total hypercholesterolemia, a 1.20-fold increase in hyper-LDL-cholesterolemia, and a high prevalence of metabolic syndrome (35% versus 25%). Nevertheless, the prevalence of hypo-HDL-cholesterolemia was significantly lower in those affected by TOS. No differences were found for other CRFs. CONCLUSION Compared to the general population, cases display a much higher prevalence of all major CRFs. However, an increase in HDL-cholesterol protective factor is in evidence for the first time.

Abstract
AbstractDietary isoflavones are thought to be cardioprotective due to their structural similarity to oestrogen. Oestrogen is believed to have beneficial effects on endothelial function and may be one of the mechanisms by which premenopausal women are protected against CVD. Decreased NO production and endothelial NO synthase activity, and increased endothelin-1 concentrations, impaired lipoprotein metabolism and increased circulating inflammatory factors result from oestrogen deficiency. Oestrogen acts by binding to oestrogen receptors α and β. Isoflavones have been shown to bind with greater affinity to the latter. Oestrogen replacement therapy is no longer thought to be a safe treatment for prevention of CVD; isoflavones are a possible alternative. Limited evidence from human intervention studies suggests that isoflavones may improve endothelial function, but the available data are not conclusive. Animal studies provide stronger support for a role of isoflavones in the vasculature, with increased vasodilation and endothelial NO synthase activity demonstrated. Cellular mechanisms underlying the effects of isoflavones on endothelial cell function are not yet clear. Possible oestrogen receptor-mediated pathways include modulation of gene transcription, and also non-genomic oestrogen receptor-mediated signalling pathways. Putative non-oestrogenic pathways include inhibition of reactive oxygen species production and up regulation of the protein kinase A pathway (increasing NO bioavailability). Further research is needed to unravel effects of isoflavones on intracellular regulation of the endothelial function. Moreover, there is an urgent need for adequately powered, robustly designed human intervention studies in order to clarify the present equivocal findings.

Abstract
The effects of 24 h supplementation of human colon carcinoma cells (Caco-2) with isoflavones, genistein, and daidzein and their activities against oleic acid hydroperoxide mediated oxidative stress were investigated. Genistein, at 25, 50, and 100 microM, and daidzein, at 25 and 50 microM, did not induce cell injury to Caco-2 cells. Both compounds reduced cell injury and DNA damage mediated by 5 microM oleic acid hydroperoxides in Caco-2 cells. The effects of genistein and daidzein on antioxidant enzymes were dependent upon the compound and its concentration.

Abstract
Some species of the genus Trifolium are well-known for their content of isoflavones, which are natural compounds showing health-promoting activities. Until recently, only a few species of this genus have been characterized with respect to their composition. In the present study, 57 Trifolium species have been analyzed for their contents of isoflavones, phenolic acids, flavonoids, and clovamides. The cluster analysis of experimental data allowed us to identify a number of species, which should be of interest as potential sources of these metabolites. The isoflavone contents of the three species ( T. heldreichianum, T. scabrum, and T. subterraneum) had extremely high amounts of these compounds, reaching 7-9% of dry matter, and the concentration in a number of other species was higher or at least comparable to the amounts occurring in T. pratense, one of the major isoflavone sources for the nutraceutical industry. Several species contained high amounts of all four analyzed groups of phenolics (isoflavones, phenolic acids, flavonoids, and clovamides). These species may also be of great interest as the association of several groups of active molecules is highly desired for effective disease prevention.

Abstract
Trends in cocaine use over the past 2 decades were compared across levels of education in a population-based US sample of adults. Significant inverse associations between educational achievement and cocaine use after 1990 were driven by dramatic decreases in persistent cocaine use among more highly educated adults, whereas persistent cocaine use remained relatively unchanged among those who did not finish high school. This emerging health disparity highlights the need for improved interventions that target persistent cocaine users with low educational achievement.

Abstract
BACKGROUND Epidemiological studies suggest a low incidence of hot flashes in populations that consume dietary soy. The present study examined the effect of soy nuts on hot flashes and menopausal symptoms. METHODS Sixty healthy postmenopausal women were randomized in a crossover design to a therapeutic lifestyle changes (TLC) diet alone and a TLC diet of similar energy, fat, and protein content in which one-half cup soy nuts divided into three or four portions spaced throughout the day (containing 25 g soy protein and 101 mg aglycone isoflavones) replaced 25 g of nonsoy protein. During each 8-week diet period, subjects recorded the number of hot flashes and amount of exercise daily. At the end of each 8-week diet period, subjects filled out the menopausal symptom quality of life questionnaire. RESULTS Compared to the TLC diet alone, the TLC diet plus soy nuts was associated with a 45% decrease in hot flashes (7.5 +/- 3.6 vs. 4.1 +/- 2.6 hot flashes day, respectively, p < 0.001) in women with >4.5 hot flashes/day at baseline and 41% in those with CONCLUSIONS Substituting soy nuts for nonsoy protein in a TLC diet and consumed three or four times throughout the day is associated with a decrease in hot flashes and improvement in menopausal symptoms.

Abstract
BACKGROUND The hypocholesterolemic effects of soy foods are well established, and it has been suggested that isoflavones are responsible for this effect. However, beneficial effects of isolated isoflavones on lipid biomarkers of cardiovascular disease risk have not yet been shown. OBJECTIVE The objective was to investigate the effects of isolated soy isoflavones on metabolic biomarkers of cardiovascular disease risk, including plasma total, HDL, and LDL cholesterol; triacylglycerols; lipoprotein(a); the percentage of small dense LDL; glucose; nonesterified fatty acids; insulin; and the homeostasis model assessment of insulin resistance. Differences with respect to single nucleotide polymorphisms in selected genes [ie, estrogen receptor alpha (XbaI and PvuII), estrogen receptor beta (AluI), and estrogen receptor beta(cx) (Tsp509I), endothelial nitric oxide synthase (Glu298Asp), apolipoprotein E (Apo E2, E3, and E4), cholesteryl ester transfer protein (TaqIB), and leptin receptor (Gln223Arg)] and with respect to equol production were investigated. DESIGN Healthy postmenopausal women (n = 117) participated in a randomized, double-blind, placebo-controlled, crossover dietary intervention trial. Isoflavone-enriched (genistein-to-daidzein ratio of 2:1; 50 mg/d) or placebo cereal bars were consumed for 8 wk, with a wash-out period of 8 wk before the crossover. RESULTS Isoflavones did not have a significant beneficial effect on plasma concentrations of lipids, glucose, or insulin. A significant difference between the responses of HDL cholesterol to isoflavones and to placebo was found with estrogen receptor beta(cx) Tsp509I genotype AA, but not GG or GA. CONCLUSIONS Isoflavone supplementation, when provided in the form and dose used in this study, had no effect on lipid or other metabolic biomarkers of cardiovascular disease risk in postmenopausal women but may increase HDL cholesterol in an estrogen receptor beta gene-polymorphic subgroup.

Abstract
BACKGROUND Previous research supports a role for soy protein in reducing serum lipids; however, few studies involved healthy male subjects or focused on soy isoflavones (or did both). OBJECTIVE The objective was to ascertain the effects of soy protein varying in isoflavone content on serum lipids in healthy young men. DESIGN Thirty-five males (x +/- SD age: 27.9 +/- 5.7 y) consumed milk protein isolate (MPI), low-isoflavone soy protein isolate (low-iso SPI; 1.64 +/- 0.19 mg aglycone isoflavones/d), and high-isoflavone SPI (high-iso SPI; 61.7 +/- 7.4 mg aglycone isoflavones/d) for 57 d each, separated by 4-wk washout periods, in a randomized crossover design. Blood samples were collected at the beginning and end of each treatment period, and total, LDL, and HDL cholesterol; triacylglycerols; apolipoprotein (apo) B; apo A-I; and C-reactive protein (CRP) were measured in serum. Twenty-four-hour urine samples were collected for 3 consecutive days at the end of each treatment period and analyzed for isoflavones. RESULTS Urinary isoflavones were significantly greater with consumption of the high-iso SPI than with that of the low-iso SPI or MPI. The differences between the 3 treatments with respect to individual serum lipids were not significant, but the ratios of total to HDL cholesterol, LDL to HDL cholesterol, and apo B to apo A-I were significantly lower with both SPI treatments than with MPI treatment. CONCLUSION Soy protein, regardless of isoflavone content, modulates serum lipid ratios in a direction beneficial for cardiovascular disease risk in healthy young men.

Abstract
BACKGROUND Age-adjusted death rates for coronary heart disease (CHD) have been decreasing in populations of developed countries. At the same time, CHD in the Asia-Pacific region appears to be increasing in parallel with the 'Westernisation' of diet and lifestyle. More epidemiological information is needed from the Asia-Pacific region in order to be able to predict trends in CHD and to plan resources for treatment. In this paper we outline the study design of a survey of coronary heart disease risk factors in Asia-Pacific countries. AIMS To ascertain and compare in 10 countries: (i) rates of measurement of risk factors; (ii) levels of risk factors, and (iii) management of risk factors. METHODS A retrospective survey was conducted in 180 randomly selected hospitals using a population-weighted sampling frame. Participating countries were Australia, Indonesia, Japan, Korea, Malaysia, New Zealand, the Philippines, Singapore, Taiwan and Thailand. Data covered a 6-month period from the patient's admission to hospital with myocardial infarction or unstable angina. Data included measures of hypertension, smoking, obesity, diabetes, dyslipidaemia and family history of coronary disease. The study design incorporated rigorous quality-assurance methods to ensure reliability. CONCLUSIONS The study will provide data comparable to those from studies in Europe and the USA. Together, these studies will provide an international perspective on coronary risk factors.

Abstract
AIM The aim of this study was to identify the dietary-related risk factors for coronary atherosclerosis among Hong Kong Chinese people. BACKGROUND Prevalence and mortality figures for coronary atherosclerosis are increasing in Chinese communities, including those in Hong Kong. Changes in dietary patterns might explain the increased risk of coronary artery disease among the Hong Kong Chinese. METHOD A total of 145 consecutive patients scheduled to have coronary angiogram in a regional hospital in Hong Kong completed a self-reported questionnaire on their dietary intake for 1 week. A case-control design was used, and the data were collected from December 2000 to February 2001. RESULTS Consumption of more than 1120 g of fish [28 tael (Chinese weight unit, 1 tael equals approximately 42 g)] per week (OR = 0.07) and soybean (OR = 0.17) had a beneficial effect in preventing coronary atherosclerosis. In addition, an increased waist-hip ratio (OR = 4.81) and consumption of more than 28 teaspoons of fat per week (OR = 42.36) were identified by logistic regression as independent risk factors for coronary atherosclerosis. Moreover, people who smoked (OR = 1.72), had a lower educational level (OR = 0.51) or higher family income (OR = 1.92) were more vulnerable to coronary atherosclerosis. Patients confirmed as having coronary atherosclerosis were more likely than those with normal coronary vessels to rank deep fry, stir fry, and pan fry as their preferred cooking methods over steaming or boiling. CONCLUSION The results provide nurses with information on which to develop appropriate health education programmes for patients and the general public in Hong Kong to promote cardiovascular health. Efforts should be directed particularly to promoting boiling and steaming as major cooking methods, rather than frying or deep frying, as protective actions against coronary atherosclerosis.

Abstract
In Vietnam, hypertension was estimated to cause a large number of deaths in hospitals. However, population-based knowledge about the magnitude of hypertension in Vietnam and its relationship with socioeconomic status, especially in the rural communities, still remains scarce. This paper, taking advantage of a study on noncommunicable disease (NCD) risk factors in Bavi district, Vietnam, using the WHO STEPs approach, estimates the prevalence of hypertension in the setting and examines its association with some socioeconomic factors. A representative sample comprising 2000 adults aged 25-64 years were selected randomly and surveyed in 2002. The JNC VII criteria for hypertension were used. Socioeconomic status of the study subjects was estimated by assessing their education, occupation and economic conditions. Descriptive techniques and multivariate logistic regression were used. The prevalence of hypertension was 14.1%. Of hypertensives, only 17.4% were aware of their hypertensive status. Men were hypertensive more often than women and age was positively associated with hypertension. The association between hypertension and socioeconomic status was complex and differed between men and women. Among men, those with lower educational and occupational status but who were richer were more likely to be hypertensive. More women with lower occupational and economic status were hypertensive.

Abstract
AIMS (1) Determination of whether isoflavones, as antioxidants and estrogen-like substances, reduce the atherosclerotic process. (2) Assessment of isoflavone anti-atherosclerotic effectiveness by means of measuring plasma markers of atherosclerosis: homocysteine (Hcy), antioxidant status, and lipid peroxidation. (3) Testing of isoflavone antioxidant effectiveness in the presence and absence of oxidative stress induced by exercise. METHODS Thirty subjects paired by aerobic fitness level were randomly assigned to either a placebo or high-genistein isoflavone extract (HGI, 150 mg/day) treatment. Blood samples were collected before and within 5 min, after 30 min at 80% peak oxygen consumption (VO(2)pk) exercise, and before and after 4-week supplementation. RESULTS Plasma genistein and daidzein were significantly increased by 4-week HGI supplementation before and after exercise (p < 0.05). HGI decreased pre-exercise (pre-ex) plasma malondialdehyde (MDA) (p < 0.05) and Hcy (p = 0.01), and increased pre-ex blood total glutathione (TGSH) (p = 0.01), but did not diminish the increase of MDA and the decrease of TGSH due to the exercise. Furthermore, HGI supplementation enhanced pre-ex total antioxidant capacity (p < 0.05), but did not influence plasma vitamin C and E and uric acid concentrations. CONCLUSION Isoflavones reduce plasma Hcy and have antioxidant activity in healthy young men. However, the effect of isoflavones on antioxidant systems may not be potent enough to diminish an abrupt surge of oxidative stress due to acute exercise.

Abstract
OBJECTIVE To determine, from population based clinical data, changes in the survival of Danish patients examined by coronary angiography for known or suspected ischaemic heart disease (IHD) during the 1990s. DESIGN Follow up study. SETTING The departments of cardiology at Rigshospitalet, Copenhagen University Hospital, and Skejby Hospital, Aarhus University Hospital, Denmark. PATIENTS Patients with IHD (n = 7021) who underwent first time coronary angiography in 1992, 1996, or 2000. MAIN OUTCOMES MEASURES Three year survival was compared between cohorts and with that of the general population. Cox proportional hazards regression was used to estimate mortality ratios adjusted for differences in patient characteristics. RESULTS Survival improved substantially--for example, adjusted mortality ratio was 0.69 (95% confidence interval (CI) 0.55 to 0.87) when comparing patients from 2000 with patients from 1992. The absolute standardised survival rates after three years of follow up were 87.1% (95% CI 85.4% to 88.8%), 89.9% (95% CI 88.5% to 91.3%), and 91.2% (95% CI 90.3% to 92.1%) among patients examined in 1992, 1996, and 2000, respectively. The improvement was not explained by the improvement in overall survival in the general population during the study period. CONCLUSIONS The survival of Danish patients with known or suspected IHD appears to have improved substantially during the 1990s.

Abstract
BACKGROUND Hong Kong has been experiencing a transition from a developing area to a developed area over the past few decades. The time trends of acute myocardial infarction (AMI) mortality would have implications for the future trends of AMI in Mainland China. METHODS Age-adjusted mortality rates during the period 1976-1999 were calculated by direct standardization with the world population using local mortality and population data. Log-linear regressions were used to estimate the annual percentage changes in mortality over different periods. Poisson regression models were used to explore the effects of age, calendar period and birth cohort. RESULTS A downward trend was observed for age-adjusted AMI mortality rate in both sexes in the 1990s, after the increasing trends in the 1970s and 1980s. The AMI mortality rate among men and women dropped by 36.4% and 37.4%, respectively. A negative annual percentage change was observed across all age groups in both sexes. Both the calendar period and the birth cohort showed significant effects on the changing AMI mortality rate, with the influence of period being stronger than the cohort, especially among males. CONCLUSION Age-adjusted AMI mortality started to decrease during the last decade. Changing life styles and a reduction of coronary risk factors could have contributed, but the improvements in medical care and effective treatment for patients suffering from AMI should have an important role.

Abstract
Consumption of soy protein is associated with a lower risk of cardiovascular disease in man, and reduced atherosclerosis in a variety of experimental animals. Although a portion of the cardiovascular protective effects appears to be due to reductions in plasma lipoprotein concentration, in most people the magnitude of this effect is relatively small. In many, but not all studies using animal models, the reduction in atherosclerosis is in part independent of changes in plasma lipids and lipoproteins. This implies that there may be a direct effect on the arterial wall of one or more of the components in soyprotein that reduces susceptibility to atherosclerosis. The most actively studied components of soy protein that may be responsible for these anti-atherogenic effects are the isoflavones and various protein factions. Extraction of isoflavones and other alcohol-soluble components from soy protein lowers, but does not eliminate its ability to reduce atherosclerosis. Surprisingly, in most studies, adding back the isoflavone-rich alcohol extract to the previously extracted soy protein, or to another protein, does not restore its lipoprotein lowering or anti-atherogenic properties. This implies that alcohol extraction either destroys an active component of soy, alters the structural integrity of the soy proteins, or disassociates a required isoflavone-soy protein complex. Understanding the mechanism of this effect is an important goal for future research. Likewise, the sites of action on the arterial wall, and the mechanisms by which various soy components act to reduce atherosclerosis are just now being studied. The recent demonstration that expression of estrogen receptor alpha is required for atheroprotection by soy protein provides important new mechanistic insight. Other properties of soy, including antioxidant, anti-inflammatory and potentially antithrombogenic properties need to be explored more mechanistically before the full potential of dietary soy protein for the protection from cardiovascular disease will be known.

Abstract
1. Epidemiological studies suggest that consumption of soy foods is associated with reduced risks of cardiovascular disease, and breast and prostate cancers. 2. Clinical intervention studies indicate that some soy components, especially soy isoflavone-containing soy protein isolate, reduced serum total cholesterol and LDL-cholesterol. 3. Animal studies generally support the conclusion that some soy components prevent the development and progression of breast and prostate cancers. 4. Epidemiological investigations and intervention studies suggest that some soy products are effective for the relief of menopausal symptoms.

Abstract
Medicine and epidemiology currently dominate the study of the strong association between socioeconomic status and mortality. Socioeconomic status typically is viewed as a causally irrelevant "confounding variable" or as a less critical variable marking only the beginning of a causal chain in which intervening risk factors are given prominence. Yet the association between socioeconomic status and mortality has persisted despite radical changes in the diseases and risk factors that are presumed to explain it. This suggests that the effect of socioeconomic status on mortality essentially cannot be understood by reductive explanations that focus on current mechanisms. Accordingly, Link and Phelan (1995) proposed that socioeconomic status is a "fundamental cause" of mortality disparities-that socioeconomic disparities endure despite changing mechanisms because socioeconomic status embodies an array of resources, such as money, knowledge, prestige, power, and beneficial social connections, that protect health no matter what mechanisms are relevant at any given time. We identified a situation in which resources should be less helpful in prolonging life, and derived the following prediction from the theory: For less preventable causes of death (for which we know little about prevention or treatment), socioeconomic status will be less strongly associated with mortality than for more preventable causes. We tested this hypothesis with the National Longitudinal Mortality Study, which followed Current Population Survey respondents (N = 370,930) for mortality for nine years. Our hypothesis was supported, lending support to the theory of fundamental causes and more generally to the importance of a sociological approach to the study of socioeconomic disparities in mortality.

Abstract
OBJECTIVE To investigate the effects of soy protein and isoflavones on blood pressure (BP) and cholesterol levels among high risk middle-aged Scottish men. DESIGN A randomized, double-blind, placebo-controlled, parallel-group dietary intervention study SETTING Inhabitants on Isles of Lewis and Harris in Scotland SUBJECTS Sixty-one men with relatively higher BP and/or total cholesterol (TC) levels aged 45 to 59 went through the dietary intervention. INTERVENTION Diets containing at least 20 g of soy protein and 80 mg of isoflavones were compared to the placebo diets. Intervention period was 5 weeks duration. RESULTS Significant difference was found in 24-hour urinary isoflavone excretion between the two groups after intervention. Significant reductions from the baselines were observed in systolic BP (SBP) and diastolic BP (DBP), TC and non-high density lipoprotein cholesterol (non-HDL-C) in the soy-containing diet group, but not in the olive oil containing active placebo group. Significant increases in high density lipoprotein cholesterol (HDL-C) were observed in both groups. CONCLUSION Dietary intakes of soy protein (at least 20 g) and isoflavones (at least 80 mg) for 5 weeks would be effective in reducing CHD risk among high-risk, middle-aged men.
