Epidemiology of cardiovascular diseases in women in Europe

Oxygen-ozone therapy for myocardial ischemic stroke and cardiovascular disorders

Cardiovascular diseases (CVDs) represent a major concern for human health worldwide. Emergencies in this field include wide repertories of studies dealing primarily with CVD prevention. In addition to dietary habits and lifestyles, medical knowledge is fully needed to improve public educational programs toward cardiovascular risk factors and to enrich the endowment of pharmaceutical options and therapies to address CVDs, particularly for ischemic damage due to an impairment in the endothelial-myocardial relationship. Because ozone is a stimulator of the endothelial nitric oxide synthase/nitric oxide pathway, ozone therapy has been widely demonstrated to have the ability to counteract endothelial-cardiac disorders, providing a novel straightforward opportunity to reduce the impact of CVDs, including atrial fibrillation. In this review, we attempt to establish a state-of-the-art method for the use of ozone in CVD, suggesting that future remarks be addressed to provide fundamental insights into this issue. The purpose of this study was to highlight the role of ozone in the adjunctive medical treatment of cardiovascular pathologies such as acute myocardial infarction due to ischemic disorders.

Trends in Health Behavior of Polish Women in 1986-2021: The Importance of Socioeconomic Status

In the last 35 years Poland has undergone a series of fundamental economic, social, and biological transformations. With the transition from a centrally planned to a free-market economy, a period of economic and social transformation, Poland's accession to the European Union, and the COVID-19 coronavirus pandemic, living conditions in the country have seen dramatic changes. The aim of this study was to assess whether there were changes in the basic health behaviors of Polish women, and if so, in what directions and with what strength, and whether there were differences in these changes depending on the socioeconomic status. Information on basic lifestyle factors (drinking alcohol, smoking, coffee drinking, and physical activity) and socioeconomic status (level of education, Gini coefficient, Gender Inequality Index, women total employment, employed women being in managerial positions, women among scientists) of 5806 women aged 40-50 years were analyzed. During the 1986-2021 period, based on the same methodology, team of technicians and research tools, six birth cohorts of women were examined in 1986, 1991, 1996, 2006, 2019 and 2021. Highly statistically significant changes were found in the frequencies of declared health behaviors from 1986-2021, according to the order of significance in coffee and alcohol consumption, physical activity levels, and smoking and smoking intensity. In subsequent cohorts, there were fewer and fewer women who did not drink coffee and alcohol, while more drank more than two cups of coffee a day and drank alcohol more often than 2× a week. Furthermore, they were more likely to be physically active, and slightly fewer were smokers. The lifestyles of the women were less likely to depend on their socio-economic status than the cohorts. In 1991 and 1996, there was a marked intensification of unhealthy behavior. Changes in the analyzed health behaviors may have been caused by adaptation to the high level of psychosocial stress observed during the transition of the 1986-2021 period and may result in changes in the biological condition and quality and length of life of Polish women. Research on social differences in health behavior provides an opportunity to analyze the biological effects of changes in the living environment.

Sex Difference Impacts on the Relationship between Paraoxonase-1 (PON1) and Type 2 Diabetes

Type-2 diabetes (T2D) and its cardiovascular complications are related to sex. Increasing evidence suggests that paraoxonase 1 (PON1) activity, an antioxidant enzyme bound to high-density lipoproteins (HDL), is implicated in the onset and clinical progression of T2D. Since we previously showed that PON1 is a sexual dimorphic protein, we now investigated whether sex might impact the relationship between PON1 and this chronic disease. To address this aim, we assessed PON1 activity in the sera of 778 patients, including controls (women, n = 383; men, n = 198) and diabetics (women, n = 79; men = 118). PON1 activity decreased in both women and men with T2D compared with controls (p < 0.05 and p > 0.001, respectively), but the change was 50% larger in the female cohort. In line with this result, the enzyme activity was associated with serum glucose level only in women (r = -0.160, p = 0.002). Notably, only within this gender category, lower PON1 activity was independently associated with increased odds of being diabetic (odds ratio (95% Confidence interval: 2.162 (1.075-5.678)). In conclusion, our study suggests that PON1-deficiency in T2D is a gender-specific phenomenon, with women being more affected than men. This could contribute to the partial loss of female cardiovascular advantage associated with T2D.

Prediabetes Is Independently Associated with Subclinical Carotid Atherosclerosis: An Observational Study in a Non-Urban Mediterranean Population

This was a prospective, observational study to compare the burden of subclinical atherosclerosis as measured by carotid ultrasonography in a cohort of subjects with prediabetes vs. subjects with normal glucose tolerance (NGT) from a non-urban Mediterranean population. Atherosclerosis was assessed through carotid intima-media thickness (c-IMT), the presence/absence of carotid plaques, and plaque number. Among 550 subjects included, 224 (40.7%) had prediabetes. The mean c-IMT and the prevalence of carotid plaque were significantly higher in the prediabetes group compared to the NGT group (0.72 vs. 0.67 mm, p < 0.001; and 37.9% vs. 19.6%; p < 0.001, respectively). Older age, male gender, and increased systolic blood pressure were positively correlated with c-IMT and were independent predictors of the presence of plaques. In contrast, prediabetes and low-density lipoprotein (LDL)-c were predictors of the presence of plaque (odds ratio [OR] = 1.64; 95% confidence interval [CI] = 1.05-2.57; p = 0.03 and OR = 1.01; 95% CI = 1.00-1.02; p = 0.006, respectively) together with tobacco exposure and the leukocyte count (OR = 1.77; 95% CI = 1.08-2.89; p = 0.023 and OR = 1.20; 95% CI = 1.05-1.38; p = 0.008, respectively). In a non-urban Mediterranean population, prediabetes was associated with established subclinical carotid atherosclerosis. These findings could have implications for the prevention and treatment of CV risk in these subjects before the first symptoms of cardiovascular disease appear.

Sex disparity persists in the prevention of cardiovascular disease in women on statin therapy compared to that in men

BACKGROUND AND AIMS

The aim of this study was to assess whether women differ from men with regard to lowering lipid levels, achieving target of optimal lipid levels, and analyzing evidence-based dose and intensity of statin prescription in primary care patients.

METHODS AND RESULTS

A multicenter cross-sectional survey was conducted among 1046 patients with dyslipidemia (554 women) who were receiving statin therapy from the Primary Health Care of Andalucía (Spain). A random sample was obtained using data from the electronic health record system. The primary outcomes were the prescription of statin therapy (intensity and dose), lowering lipid levels, and achieving target of optimal lipid levels. Women were less likely to be treated with a more potent statin than men (9.2% vs. 14.4%, p = 0.009), and they received lower doses (45 ± 59 mg/day vs. 56 ± 71 mg/day, p = 0.004) than men. Total cholesterol and LDL-C levels were higher in women than in men (5.7 ± 1.3 mmol/l vs. 5.2 ± 1.2 mmol/l, p < 0.0001 and 3.5 ± 1.2 mmol/l vs. 3.1 ± 1.0 mmol/l, p < 0.0001, respectively). Compliance with established goals for total cholesterol (47.7% vs. 31.3%, p < 0.0001) and LDL-C (39.7% vs. 25.4%, p < 0.0001) was superior in men than in women. In multivariate analysis, adjusted for age, the variables male gender and CVD were associated with a higher compliance with total cholesterol and LDL-C target levels, and the variable diabetes mellitus 2 was associated with a lower compliance with HDL-C and triglycerides target levels.

CONCLUSIONS

Women were less likely to be prescribed high-intensity statin to achieve total cholesterol and LDL-C target levels, and mean doses of statin were lower in women than in men. Dyslipidemia is less closely controlled in women than in men.

Two tales of cardiovascular risksmiddle-aged women living in Sweden and Scotland: a cross-sectional comparative study

OBJECTIVES

To compare cardiovascular risk factors as well as rates of cardiovascular diseases in middle-aged women from urban areas in Scotland and Sweden.

DESIGN

Comparative cross-sectional study.

SETTING

Data from the general population in urban areas of Scotland and the general population in two major Swedish cities in southeast Sweden, south of Stockholm.

PARTICIPANTS

Comparable data of middle-aged women (40-65 years) from the Scottish Health Survey (n=6250) and the Swedish QWIN study (n=741) were merged together into a new dataset (n=6991 participants).

MAIN OUTCOME MEASURE

We compared middle-aged women in urban areas in Sweden and Scotland regarding risk factors for cardiovascular disease (CVD), CVD diagnosis, anthropometrics, psychological distress and lifestyle.

RESULTS

In almost all measurements, there were significant differences between the countries, favouring the Swedish women. Scottish women demonstrated a higher frequency of alcohol consumption, smoking, obesity, low vegetable consumption, a sedentary lifestyle and also more psychological distress. For doctor-diagnosed coronary heart disease, there were also significant differences, with a higher prevalence among the Scottish women.

CONCLUSIONS

This is one of the first studies that clearly shows that Scottish middle-aged women are particularly affected by a worse profile of CVD risks. The profound differences in CVD risk and outcome frequency in the two populations are likely to have arisen from differences in the two groups of women's social, cultural, political and economic environments.

Cardiovascular risk factors in pre-pubertal schoolchildren in Angola

METHODS

The incidence of obesity is increasing worldwide, especially in countries with accelerated economic growth. We determined the prevalence of and associations between overweight/obesity and cardiovascular risk factors in pre-pubertal (seven- to 11-year-old) schoolchildren (both genders, n = 198) in Luanda, Angola. Biochemical (fasting blood) and clinical examinations were obtained in a single visit. Data are reported as prevalence (95% confidence intervals) and association (r, Pearson).

RESULTS

Prevalence of overweight/obesity was 17.7% (12.4- 23.0%), high blood pressure (BP > 90% percentile) was 14.6% (9.7-19.5%), elevated glucose level was 16.7% (11.5-21.9%) and total cholesterol level > 170 mg/dl (4.4 mmol/l) was 69.2% (62.8-75.6%). Significant associations between body mass index (BMI) and systolic and diastolic BP (r = 0.46 and 0.40, respectively; p < 0.05) were found. No association between BMI and elevated glucose or cholesterol levels was found.

CONCLUSION

The prevalence of cardiovascular risk factors was high in pre-pubertal schoolchildren in Angola and fat accumulation was directly associated with blood pressure increase but not with other cardiovascular risk factors.

Racial and Ethnic Disparities in Cardiovascular Disease: An Assessment of Obstetrician-Gynecologists' Knowledge, Attitudes, and Practice Patterns

BACKGROUND

African American and Hispanic women are disproportionately affected by cardiovascular disease (CVD) and its many risk factors. Obstetrician-gynecologists (OB/GYNs) play an integral role in well-woman care and have a unique opportunity to provide CVD counseling and screening to these at-risk and underserved groups.

OBJECTIVE

To assess whether OB/GYN race/ethnicity and OB/GYN practices with increasing minority patient populations predicted differences in OB/GYNs' knowledge, attitudes, and practice patterns relevant to racial/ethnic disparities in CVD. This study also sought to determine provider and patient-related barriers to CVD care.

METHOD

A questionnaire on CVD was mailed to 273 members of The American College of Obstetricians and Gynecologists in March-July 2013.

RESULTS

African American and Hispanic OB/GYNs and OB/GYN practices with increasing minority patient populations were more knowledgeable of CVD disparities. These OB/GYNs reported greater concern for minority women's CVD risk relative to White OB/GYNs. Overall, OB/GYNs appear less knowledgeable and concerned with Hispanics' increased CVD risk relative to African Americans'. The most commonly reported provider and patient-related barriers to CVD care were time constraints, patient nonadherence to treatment recommendations, and inadequate training.

CONCLUSION

It is likely that minority OB/GYNs and those with practices with increasing minority patient populations have greater exposure to women at risk for CVD. Dissemination of educational information regarding Hispanic women's CVD risk profile may improve OB/GYN knowledge, counseling, and screening. Increased training in CVD and multicultural competency during medical school and residency should help OB/GYNs overcome what they report as primary barriers to CVD care.

The analysis of cumulative influence of factors of environment on a state of health of the population of Vladimir region

There was investigated the contribution of factors of environment to formation of health for adult population on indicators of mid-annual rates of growth/decrease of disease of system of blood circulation and of some interfaced nosology on an example of the population of Vladimir region. The differential criterion of primary disease of system of blood circulation is considered as an indicator, integrally reflecting degree of adaptation to environment conditions on population and suitable for construction short-term prognostic estimations.

It is shown that business factors or the factors of a standard of living characterized by economic indicators, are leading risk factors in disease of system of blood circulation in Vladimir region which contribution is estimated by size of 38 %.

With use of regressive equations were received look-ahead estimations of annual rates of primary disease of system of blood circulation. In the regional centre Vladimir was observed more intense situation on rates of disease of system of blood circulation, than in Vladimir region.

A new predictive equation for evaluating women body fat percentage and obesity-related cardiovascular disease risk

BACKGROUND

Obesity represents a global public health problem due to its association with cardiovascular diseases and reduced lifespan. The most widely used classification of obesity is expressed as Body Mass Index (BMI); however, this formula is an imprecise adiposity measurement that ignores several important factors involved. Body Adiposity Index (BAI) was more recently proposed as an indirect evaluation of percentage body fat (PBF). PBF is a direct measure of person's relative body fat and a better predictor of obesity-related risk diseases than BMI and BAI. Since obesity and consequent diseases are considered epidemic, new accurate formulas for epidemiological studies are of interest to the scientific community. Because direct measurement of body composition could be quite expensive, the aims of our work were to analyse the distributions of PBF by Dual X-ray absorptiometry, and the creation of new predictive equation using only anthropometric measures that could be helpful to clinicians to assess easily body fat of female patients.

METHODS/RESULTS

A sample of 1,031 Caucasian Italian women was recruited and BMI, BAI and PBF were evaluated. With the aim of developing a predictive model of PBF a multivariate regression model was fitted to observed data.

CONCLUSIONS

The definition of universally recognized PBF by gender and age could have public health implications. In this study, we developed a new predictive PBF equation that does not require the use of medical instruments or skilled measurement techniques and that may be easily applicable to Italian women.

Effectiveness of motor imagery or mental practice in functional recovery after stroke: a systematic review

INTRODUCTION

In recent decades, many stroke rehabilitation methods have been developed. Mental practice (MP) is a dynamic state in which the subject evokes an imaginary representation of a motor action or skill in order to learn or perfect that action. Although functional imaging has shown that MP produces similar cortical activation patterns to those of movement, the clinical effectiveness of such methods in rehabilitation and functional recovery has yet to be demonstrated.

DEVELOPMENT

Systematic search of all clinical studies published in the main scientific databases between December 2011 and October 2012 concerning mental practice in stroke rehabilitation. We selected 23 clinical trials testing different MP protocols in patients with hemiparesis.

CONCLUSIONS

MP is effective when used in conjunction with conventional physical therapy for functional rehabilitation of both upper and lower limbs, as well as for the recovery of daily activities and skills. Owing to the heterogeneity of the studies with regard to the intervention protocol, specific imagery technique, time spent practicing, patient characteristics, etc., more studies are needed in order to determine the optimal treatment protocol and patient profile.

Women show worse control of type 2 diabetes and cardiovascular disease risk factors than men: results from the MIND.IT Study Group of the Italian Society of Diabetology

BACKGROUND AND AIMS

The study explores the degree of control of hyperglycaemia and cardiovascular (CV) disease risk factors in men and women with type 2 diabetes and the impact thereon of obesity, central adiposity, age and use of medications.

METHODS AND RESULTS

A cross-sectional survey was conducted at 10 hospital-based outpatients diabetes clinics. 1297 men and 1168 women with no previous CV events were studied. Women were slightly (only one year) older and more obese than men: average BMI was respectively 30.7 ± 5.7 vs 28.6 ± 4.1 kg/m(2) (p < 0.001), and prevalence of abdominal obesity was 86% vs 44% (p < 0.001). Women smoked less, but had higher HbA1c, LDL cholesterol, non-HDL cholesterol, systolic blood pressure and serum fibrinogen than men. Accordingly optimal targets for HbA1c (<7%), LDL cholesterol (<100 mg/dL), HDL cholesterol (>40 for men, >50 for women, mg/dL), and systolic blood pressure (<130 mmHg) were less frequently achieved by women than men (respectively 33.8% vs 40.2%; 14.6% vs 19.2%; 34.1% vs 44.5%; 68.8% vs 72%; p < 0.05 for all). Findings were confirmed after stratification for waist circumference (< or ≥ 88 cm for women; < or ≥ 102 cm for men), BMI (< or ≥ 25 kg/m(2)) or age (< or ≥ 65 years). As for treatment, women were more likely than men to take insulin, alone or in combination with oral hypoglycaemic drugs, to be under anti-hypertensive treatment, whereas the use of lipid lowering drugs was similar in men and women.

CONCLUSIONS

Control of hyperglycaemia and major CVD risk factors is less satisfactory in women than men. The gender disparities are not fully explained by the higher prevalence of total and central obesity in women; or by a less intensive medical management in women.

Cardiovascular disease prevention in women: a rapidly evolving scenario

The past decade has witnessed a long overdue recognition of the importance of CVD in women, accompanied by an increasing awareness of gender differences in risk factors, natural history, preventive strategies, treatment, and prognosis of CVD. Reflecting the disease burden and the specific aspects of CVD in women, the American Heart Association has developed women-specific evidence-based guidelines and consensus documents for CVD prevention. The most recent update of these guidelines, published in 2011, is a milestone in the field and shows the rapidly evolving scenario of CVD prevention in women. We discuss some novel aspects of the 2011 update. The new guidelines change the focus from evidence-based to effectiveness-based, with consideration of both benefits and harms/costs of preventive interventions. The guidelines also introduce "ideal cardiovascular health" as the lowest category of risk, which implies the need of communitywide preventive, educational and policy initiatives to promote healthy lifestyles in the general population. Furthermore, the guidelines emphasize long-term overall CVD risk rather than short-term coronary risk. We also address several barriers and open questions in the evaluation and implementation of these guidelines, including how to increase the small proportion of women with ideal cardiovascular health; how to increase implementation and compliance with the recommendations; how to provide effectiveness-based recommendations for lifetime prevention goals based on short-term trials; how to obtain the best possible evidence in women; how to identify subgroups of women with different cardiovascular risk profiles or who may require tailored preventive strategies; and how to adapt current guidelines to international settings, particularly to low- and middle-income countries.

Adiposity rather than BMI determines metabolic risk

BACKGROUND AND AIM

There is increasing evidence suggesting that WHO body mass index (BMI) cut-off values are outdated and should not be applied to different population. To overcome misclassifications, direct measurements of percentage body fat (PBF) would be a better tool for preobesity and obesity diagnosis. The aim of this study was to analyze the body composition in a adult population in Centre-South of Italy, by age and gender, and to verify the accordance between BMI and PBF cut-off points for health status classification.

METHODS

The total subject pool cover a total of 4408 participants adults. A completed screening of anthropometry and body composition by Dual X-ray Absorptiometry, (DXA) was assessed on 3.258 subjects.

RESULTS

Distributions and quantitative reliable estimates of PBF, total body fat and lean, according to gender and age are provided. The prevalence of "at risk" subjects (preobese and obese) was 69% and 85%, for men and women respectively, according to PBF cut-off points. The agreement of BMI and PBF categories resulted low for the total and male population, even scarce for female population (all P ≤ 0.001). The false negative classification of BMI was stronger for women than men and for younger than older subjects.

CONCLUSIONS

Screening for adiposity in subjects with a normal BMI could better identify those at higher risk for cardiometabolic disturbances and cardiovascular mortality. The herein used cut-offs points of PBF, by age and gender, may provide a useful reference in clinical settings and public health services, in particular for the Italian Caucasian population.

Bacterial biofilms associated with food particles in the human large bowel

Bacteria within the gastro-intestinal tract affect host function via production of short-chain fatty acids and synthesis of vitamins. Additionally, the commensal enteric bacteria modulate the immune system and provide protection from potentially pathogenic bacteria. Only recently heterogeneous bacterial biofilms were found to be associated with food particles within the intestinal tract. There are a number of studies investigating the formation and function of pathogenic and single-species biofilms, though few studies have investigated the dynamics of multispecies biofilms, especially with regard to food/microbial/host interactions. The scope of this review is to discuss the current knowledge of bacterial biofilms associated with food particles in the human large bowel, examine the established mathematical models depicting bacterial attachment, and elucidate key areas for further research.
