Burden of Cardio- and Cerebro-vascular Diseases and the Conventional Risk Factors in South Asian Population

Role of encapsulation on the bioavailability of omega-3 fatty acids

Omega-3 fatty acids (omega-3 FAs) have been widely recognized for their therapeutic advantages, including anti-inflammatory and cardioprotective properties. They have shown promise in enhancing regulatory function, promotingdevelopment and mitigating the progression of diabetes and cancer. The scientific communities, along with industries, are actively endorsing initiatives aimed at increasing the daily intake of lipids rich in omega-3 FAs. Nevertheless, incorporating polyunsaturated FAs (PUFAs) into food products poses several challenges due to their susceptibility to oxidation when exposed to oxygen, high temperatures, and moisture. This oxidative deterioration results in undesirable flavours and a loss of nutritional value. Various methods, including physical blending, interesterification, and encapsulation, have been utilized as ways to enhance the stability of edible oils rich in PUFA against oxidation. Encapsulation has emerged as a proven strategy for enhancing the oxidative stability and functional properties of omega-3 FA-rich oils. Multiple encapsulation methods have been developed to stabilize and improve the delivery of omega-3 FAs in food products. The selection of an appropriate encapsulation method depends on the desired application of the encapsulated oil. In addition, encapsulation enhances the bioavailability of omega-3 FAs by promoting increased absorption of the encapsulated form in the intestinal epithelium. This review discusses the techniques and principles of omega-3 FA-rich oil encapsulation and its role in improving stability and bioavailability. Furthermore, it also investigates the potential health benefits of these encapsulated oils. This review explores the variations in bioavailability based on encapsulation techniques and processing, offering vital insights for nutrition and product development.

Surveillance of stroke: a South-East Asia Region (SEAR) perspective

Surveillance of stroke is critical to track its burden and assess progress in prevention and treatment. We reviewed the literature to evaluate stroke surveillance efforts in the South-East Asia Region (SEAR) countries, identify progress and assess gaps. Epidemiological data on all the major parameters such as the incidence, prevalence and mortality of stroke were available for India and Thailand but for none of the other SEAR countries. Most of the epidemiological data came from investigator-initiated studies. National stroke surveillance was present only in India in the form of a National Stroke Registry Programme and Thailand has a national database that was used to obtain epidemiological data for stroke. Research on novel methods for stroke registration, such as using information technology, was absent. This review identified serious gaps in the monitoring and surveillance of stroke in SEAR countries. Systematic efforts are needed to fill those gaps.

Risk Assessment for Cardiovascular Disease Using the Framingham Risk Score and Globorisk Score Among Newly Diagnosed Metabolic Syndrome Patients

Purpose

The presence of metabolic syndrome (MetS) is linked to an increased risk of cardiovascular disease (CVD) development. In this study, CVD risk was calculated among individuals with newly diagnosed MetS using the Framingham Risk Score (FRS) and Globorisk Score. The FRS and Globorisk score are particularly relevant in predicting CVD risk as these scores include key MetS-related risk factors like blood pressure, cholesterol levels, and age.

Patients and Methods

A community-based cross-sectional study was conducted at various sites in Karachi, Pakistan, from February 2022 to August 2022. Newly diagnosed cases of MetS with no physical disability, known illness, and not taking any regular medication were recruited. MetS was defined based on the definition of International Diabetes Federation. The major outcome was 10-year risk for CVD using the FRS and Globorisk Score.

Results

Of 304 patients, 59.2% were classified as low risk according to FRS, while 20.4% were classified as moderate and high risk each. Using the Globorisk score, 44.6% of 224 patients were classified as low risk, 34.4% as moderate risk, and 21.0% as high risk. A moderate positive correlation was observed between the two CVD risk scores (r = 0.651, 95% CI 0.58-0.71). Both risk scores have reported age, gender, and current smokers as significant risk factors in predicting CVD in 10-years (P < 0.05).

Conclusion

The outcome of both CVD risk scores predicted moderate-to-high risk of CVD in 10-years in almost half of the newly diagnosed patients with MetS. In particular, the risk of development of CVD in 10-years in newly diagnosed MetS is higher with increasing age, in male gender, and current smokers.

Sex and Gender Determinants of Vascular Disease in the Global Context

Globally, vascular diseases are a leading cause of morbidity and mortality. Many of the most significant risk factors for vascular disease have a gendered dimension, and sex differences in vascular diseases incidence are apparent, worldwide. In this narrative review, we provide a contemporary picture of sex- and gender-related determinants of vascular disease. We illustrate key factors underlying sex-specific risk stratification, consider similarities and sex differences in vascular disease risk and outcomes with comparisons of data from the global North (ie, developed high-income countries in the Northern hemisphere and Australia) and the global South (ie, regions outside Europe and North America), and explore the relationship between country-level gendered inequities in vascular disease risk and the United Nation's gender inequality index. Review findings suggest that the rising incidence of vascular disease in women is partly explained by an increase in the prevalence of traditional risk factors linked to gender-related determinants such as shifting roles and relations related to the double burden of employment and caregiving responsibilities, lower educational attainment, lower socioeconomic status, and higher psychosocial stress. Social isolation partly explained the higher incidence of vascular disease in men. These patterns were apparent across the global North and South. Study findings emphasize the necessity of taking into account sex differences and gender-related factors in the determination of the vascular disease risk profiles and management strategies. As we move toward the era of precision medicine, future research is needed that identifies, validates, and measures gender-related determinants and risk factors in the global South.

A Machine learning-based prediction model for the heart diseases from chance factors through two-variable decision tree classifier

This paper addressed the prediction of heart sicknesses from hazard elements through a decision-making tree. We introduced the facts mining technique in public fitness to extract high-degree knowledge from raw data, which facilitates predicting heart diseases from risk factors and their prevention. The existing work intends to introduce a new risk element in heart diseases using novel data mining strategies. Latest actual international affected person’s information (e.g., smoking, area of residence, age, weight, blood stress, chest pain, low-density lipoproteins (LDL), high-density lipoproteins (HDL), block arteries became accrued by way of the use of questionnaire through direct interview technique from patients. Novel two-variable decision trees are constructed for coronary heart illness records primarily based on chance factors and ranking of risk elements. The results show a correct prediction of cardiovascular disease (CVD) from the risk factor if records on chance factors are available as direct results of this study, tobacco, loss of physical exercise, and weight-reduction plan play a vital role in predicting heart diseases, which is the most important reason for mortality in developing countries, especially in my country.

Abdominal obesity and metabolic syndrome in South Asians: prevention and management

INTRODUCTION

The prevalence of metabolic syndrome (MetS) and abdominal obesity are escalating in South Asian countries. It is well established that MetS is associated with increased risk for both Type 2 diabetes mellitus and cardiovascular diseases. South Asians have an increased risk of MetS due to a variety of factors including unhealthy lifestyle and their unique body composition.

AREAS COVERED

In this review, we discuss the prevalence, associated risk factors, and evidence-based preventive and curative strategies for MetS and abdominal obesity in South Asians. A literature search through PubMed®, Web of Science®, and Scopus® was performed for studies published before 31^st April 2021. A combination of the following keywords was used with the names of the individual South Asian countries: 'metabolic syndrome,' 'syndrome X,' 'abdominal obesity,' 'central obesity,' 'visceral obesity,' 'prevention,' and 'management.'

EXPERT OPINION

According to current evidence, MetS and abdominal obesity are highly prevalent among South Asians. Several risk factors, such as lifestyle, socio-demography, cultural, and body composition, are associated with MetS. Limited research shows culturally tailored lifestyle interventions are effective in preventing and managing MetS and abdominal obesity among South Asians.

Secular trends in cardiovascular risk factors among urban and rural populations in Tamil Nadu, India - An ancillary analysis of the STRiDE-I study

AIMS

To study changes in cardiovascular (CV) risk factors; hypertension (HTN), dysglycaemia (DG) and dyslipidaemia (DL) and their interrelationship, in urban and rural Southern India, in a decade.

METHODS

Epidemiological data of a city (Chennai, n = 2192(2006), n = 3850(2016)) and peri-urban villages (Panruti, n = 2584 (2006), n = 2468 (2016)) among persons aged ≥ 20 years in 2006 and in 2016 were analysed. Age-standardized prevalence, prevalence ratios and interrelationships of HTN, DG and DL and effect of time in years, age, gender and obesity were calculated using Poisson regression analyses.

RESULTS

Response rates in urban and rural areas were 86.5% and 87.6% respectively. Mean age, general obesity (GO), abdominal obesity (AO), total calories and carbohydrate intake increased in both populations (p < 0.0001). Rural population had lower BMI than the urban but had higher AO, particularly among women. Physical activity decreased only in the urban population. HTN increased in urban population; in both, proportion of known HTN decreased, DG and DL increased.

CONCLUSIONS

In both populations, GO, AO, DG and DL increased; AO and DL were more common among rural women. HTN did not increase in the rural population. The risk factors increased rapidly even in rural areas projecting the impact of urbanisation on the CV burden.

Association of health literacy and medication adherence with health-related quality of life (HRQoL) in patients with ischemic heart disease

BACKGROUND

Medication Adherence (MA) and Health Related Quality of Life (HRQoL) are two inter-connected concepts, co-influenced by Health Literacy (HL), with significant impact on patient management and care. Thus, we aimed to estimate the association of HL and MA with HRQoL in IHD patients.

METHODS

Cross-sectional study of 251 IHD patients recruited from Lahore over 6 months period. HL, MA and HRQoL was assessed using validated questionnaires; 16-items of HL, Morisky Green Levine Scale (MGLS) and SF-12, respectively. Chi-square for significance, logistic-regression for association and linear regression for predictions were used.

RESULTS

IHD patients; males (p = 0.0001), having secondary-higher education (p = 0.0001), middle/upper class (p = 0.0001) and employed (p = 0.005) had adequate HL, and were more likely to be adherent (OR; 4.3, p = 0.014). Both physical (PCS-12) and mental (MCS-12) component scores of HRQoL for age, gender, education, area of residence, employment and MA were significantly higher in patients with adequate HL. In multinomial regression, improved PCS-12 scores tend to be higher in subjects having secondary-higher education (OR; 3.5, p = 0.067), employed (OR; 6.1, p = 0.002) and adherent (OR; 2.95, p = 0.218), while MCS-12 scores tend to be higher in patients < 65 years (OR; 2.2, p = 0.032), employed (OR; 3, p = 0.002) and adherent (OR; 4, p = 0.004). In adjusted model, HL (β;0.383, p = 0.0001) and MA (β; - 0.133, p = 0.018) were significantly associated with PCS-12, and MCS-12 with MA (β; - 0.161, p = 0.009) only.

CONCLUSION

Data suggested that adequate HL was significantly associated with adherence and both physical and mental dimensions of HRQoL were higher in IHD patients with adequate HL. Besides, HL and MA are independent predictors of HRQoL in IHD patients.

Prevalence and Risk Factors of Cardiovascular Diseases among Bangladeshi Adults: Findings from a Cross-sectional Study

Ever rising prevalence of Cardiovascular Diseases (CVD) is a major challenge for the health sector in Bangladesh. This study aimed to explore the prevalence of CVD and sociodemographic and lifestyle factors associated with it in Bangladesh. The data were collected through a cross-sectional survey following a two-stage cluster random sampling procedure. The present analysis was performed among 12,338 respondents aged ≥35 years, selected from rural areas and urban slums. Information was gathered using a structured questionnaire, whereas measurements were taken using standardized procedures. Logistic regression with exchangeable correlation structure among clusters was executed to explore the association. About 30% of participants had hypertension, 5% diabetes, 20% obesity; 77% were either smokers or consumed smokeless tobacco, and 28% were physically inactive. The prevalence of CVD was 4.5% (stroke: 1.8% and heart diseases: 3.2%). After adjusting for potential confounders, hypertension, diabetes, body mass index, extra salt intake, daily sleep, tiredness, age, gender, occupation, administrative division, and wealth quintile were found to be significantly associated with CVD. The study highlighted that the prevalence of CVD is high in Bangladesh, and its associated risk factors such as hypertension and diabetes are on the rise, especially in the older population, women, and high-income groups. Therefore, immediate public health intervention is warranted to address the issue.

Prevalence and predisposing factors for self-reported hypertension in Bhutanese adults

Background:

Bhutan underwent a nutrition transition in the last two decades. Diet has changed from high-fibre, high carbohydrate and low-fat diets to food with high sugar, fat, salt and processed foods. This is further compounded by a sedentary lifestyle. This paper aims to determine the national prevalence of hypertension and study the associated correlates in Bhutanese adults.

Materials and Methods:

This study used secondary data from the Bhutan National Health Survey 2012 (NHS, 2012) which was a nationwide survey covering all 20 districts in Bhutan. The dependent variable was self-reported hypertension under medication. Multivariable logistic regression was undertaken to identify independent correlates of hypertension.

Results:

The national prevalence of hypertension was 17.4% (5,408). Risk factors for hypertension were female sex, increasing age, occupation of armed forces, manager, technician, service and sales worker, machine operator and monks, diabetes, and feeling worried. Being single was negatively correlated with hypertension. In addition, hypertension is negatively associated with the poverty of the district.

Conclusion:

Hypertension was associated with age, being women, occupation with less physical activity, being worried and having diabetes. The preventive measures both at community and healthcare facility-based through cost-effective strategies should target these covariates.

Prevalence of Cardiac Risk Factors and Attitude toward Self-Risk Assessment among Cardiac Care Givers

Objective:

Aim of this survey was to assess the prevalence of cardiovascular diseases (CVD) risk factors and attitude toward self-risk assessment among cardiac care physicians (who did not have CVD history), at a tertiary care cardiac center in Pakistan.

Design:

In this survey we included cardiac care givers who had a minimum of 1 year of working experience in a cardiac care center.

Participants:

Participants with self-reported history of established diagnosis of CVD were excluded. Face-to-face interviews were conducted with the help of a structured questionnaire which consisted of demographic information, data regarding established CVD risk factors, self-awareness, and attitude toward CVD risk assessment.

Results:

A total of 126 participants were interviewed, out of which 20.6% (26) were females and mean age was 36.1±7.6 years. The most prevalent CVD risk factor was family history of CVD (33.3%) followed by smoking (14.3%) and 23.8% had body mass index of ≥27.5 kg/m². Around 23% of the participants did not know their cholesterol levels, similarly more than 74% were not aware of their high-density lipoproteins levels. More than 76% had never assessed their CVD risk and more than 37% don’t know or don’t have any opinion about their own CVD risk.

Conclusions:

The present study reveals low prevalence of conventional cardiac risk factors and marginally higher tendency of modifiable risk factors, such as smoking and obesity, among the cardiac physicians. A large proportion of these cardiac physicians have not yet assessed their CVD risk.

Governmental designation of emergency medical institutes: 30 days mortality by types of designation

BACKGROUND

In 2000, the South Korean government introduced a program in emergency medical institutions throughout the country to establish effective management system for emergency patients. The aim of this study was is to investigate the effectiveness of this program for emergency patients and establish evidence for more effective strategy by comparing the relationship between types of emergency medical center and 30 day mortality after hospitalization in inpatients with cerebrovascular and cardiovascular diseases.

METHODS

We used National Health Insurance claim data (n = 111,741) from 115 hospitals during 2010-2013 to analyze readmissions within 30 days after hospitalization due to cerebrovascular and cardiovascular diseases. We performed χ2 tests, analysis of variance and logistic regression analysis using generalized estimating equation (GEE) modeling to investigate associations with 30 day mortality after hospitalization.

RESULTS

Deaths within 30 days of hospitalization due to cerebrovascular and cardiovascular diseases were 6.5%. Regional emergency medical center and localized emergency medical center had lower risk in 30 days mortality after hospitalization than localized emergency medical agency (regional emergency medical center = OR: 0.71, 95 CI: 0.60-0.84; localized emergency medical center = OR: 0.81, 95% CI: 0.72-0.90; ref. = localized emergency medical agency). In addition, reduction in 30 days mortality by types of emergency medical institutes was more highly associated in cerebrovascular diseases than cardiovascular diseases.

CONCLUSIONS

Government designated higher level emergency medical institutes had better outcomes in emergency medical care than localized emergency medical agencies. Thus, health policy makers have to consider optimal reimbursement in the field of emergency medicine.

Prevalence of cardiovascular disease among Bangladeshi adult population: a systematic review and meta-analysis of the studies

BACKGROUND

Cardiovascular disease (CVD) is a group of conditions affecting the functioning of the heart or blood vessels and is one of the leading causes of death globally. Like other countries, CVD prevalence is also rising among the adults in Bangladesh. Epidemiological studies have shown not only a high CVD prevalence but also a significant increase in its prevalence in Bangladesh in the last few decades. To have a better understanding of the current CVD prevalence scenario, we conducted this systematic review and meta-analysis. Our objective was to assess the prevalence of CVD among the Bangladeshi adult population using evidence from the published scientific literature.

METHODS

Electronic databases such as MEDLINE, Embase and PubMed were searched. We also manually checked the references of all relevant publications that describe the prevalence of CVD in Bangladeshi adults. To pool the CVD prevalence, we used random-effects meta-analysis. We assessed heterogeneity using both the formal tests and the subgroup analyses. We also assessed study quality and examined publication bias.

RESULTS

We retrieved 755 potentially relevant papers through searches of electronic and gray literature, of which only 13 met inclusion criteria after the screening and were included in this review. Of the studies that met inclusion criteria, three were carried out in rural populations, five in both urban and rural populations and two in strictly urban populations. Male and female participation in the studies was almost equal. The weighted pooled prevalence of CVD was 5.0%, regardless of the types of CVD, gender and geographical location of the study participants. There was also a high heterogeneity in the observed CVD prevalence. Weighted pooled prevalence of overall CVD in the Bangladeshi population was higher in urban areas (8%) compared to rural areas (2%). However, no such difference was observed in terms of gender (3% for both males and females). The highest reported prevalence (21%) was for heart disease, while the lowest reported prevalence (1%) was for stroke. Sources of heterogeneity were often unexplained. The criteria used to assess study quality were fulfilled by only a few studies, and adequate sample size criteria was missed by almost all of them. In addition, there was evidence of small-study effects.

CONCLUSION

A high CVD prevalence along with an upward trend was observed in Bangladeshi adults. Proper strategies are required for primary prevention of CVD so that a further increase can be alleviated and the morbidity and mortality associated with it can be reduced.

Immigration and dietary patterns in South Asian Canadians at risk for diabetes

AIM

To examine the relationship between immigration and dietary patterns among South Asian adults at risk for diabetes and living in Canada.

METHODS

We recruited 428 South Asian adults affiliated with Sikh and Hindu temples in Metro Vancouver. Of the total sample, 422 completed self-report surveys including demographic background information, and two brief food screeners (fruit/vegetable/fiber intake and fat intake). Food screeners were culturally tailored to include traditional foods consumed in the South Asian community.

RESULTS

Multiple linear regressions examined the relationship between diet and immigration. All models were adjusted for age, sex, marital status, education, income, and employment. Participants reported low levels of meat, fruit and vegetable consumption. Intake of whole milk products, traditional South Asian desserts and snacks were relatively high in comparison to other fat-containing food items. Specific trends in diet were seen in relation to time following immigration with the longer duration of years living in Canada the greater consumption of fruit/vegetable/fiber, non-starchy vegetables, total fat and meat reported; and lower intake of whole milk.

CONCLUSION

Acculturation appears to influence some dietary patterns in our sample of South Asian Canadian adults. These findings should be considered when designing culturally tailored lifestyle modification interventions for this community.

Emerging Burden of Cardiovascular Diseases in Bangladesh

As a result of an epidemiological transition from communicable to non-communicable diseases for last few decades, cardiovascular diseases (CVD) are being considered as an important cause of mortality and morbidity in many developing countries including Bangladesh. Performing an extensive literature search, we compiled, summarized, and categorized the existing information about CVD mortality and morbidity among different clusters of Bangladeshi population. The present review reports that the burden of CVD in terms of mortality and morbidity is on the rise in Bangladesh. Despite a few non-communicable disease prevention and control programs currently running in Bangladesh, there is an urgent need for well-coordinated national intervention strategies and public health actions to minimize the CVD burden in Bangladesh. As the main challenge for CVD control in a developing country is unavailability of adequate epidemiological data related to various CVD events, the present review attempted to accumulate such data in the current context of Bangladesh. This may be of interest to all stakeholder groups working for CVD prevention and control across the country and globe.

Cardiovascular risk models for South Asian populations: a systematic review

OBJECTIVES

To review existing cardiovascular risk models applicable to South Asian populations.

METHODS

A systematic review of the literature using a combination of search terms for "South Asian", "cardiovascular", "risk"/"score" and existing risk models for inclusion. South Asian was defined as those residing in or with ancestry belonging to the Indian subcontinent.

RESULTS

The literature search including MEDLINE and EMBASE identified 7560 papers. After full-text review, 4 papers met the inclusion criteria. Only 1 reported formal measures of model performance. In that study, both a modified Framingham model and QRISK2 showed similar good discrimination with AUROCs of 0.73-0.77 with calibration also reasonable in men (0.71-0.93) but poor in women (0.43-0.52).

CONCLUSIONS

Considering the number of South Asians and prevalence of cardiovascular disease, very few studies have reported performance of risk scores in South Asian populations. Furthermore, it was difficult to make comparisons, as many did not provide measures of discrimination, accuracy and calibration. There is a need for further research to evaluate risk models in South Asians, and ideally derive and validate cardiovascular risk models within South Asian populations.

Low dietary diversity and micronutrient adequacy among lactating women in a peri-urban area of Nepal

OBJECTIVE

The main objectives were to assess the adequacy of the micronutrient intakes of lactating women in a peri-urban area in Nepal and to describe the relationships between micronutrient intake adequacy, dietary diversity and sociodemographic variables.

DESIGN

A cross-sectional survey was performed during 2008-2009. We used 24 h dietary recall to assess dietary intake on three non-consecutive days and calculated the probability of adequacy (PA) of the usual intake of eleven micronutrients and the overall mean probability of adequacy (MPA). A mean dietary diversity score (MDDS) was calculated of eight food groups averaged over 3 d. Multiple linear regression was used to identify the determinants of the MPA.

SETTING

Bhaktapur municipality, Nepal.

SUBJECTS

Lactating women (n 500), 17-44 years old, randomly selected.

RESULTS

The mean usual energy intake was 8464 (sd 1305) kJ/d (2023 (sd 312) kcal/d), while the percentage of energy from protein, fat and carbohydrates was 11 %, 13 % and 76 %, respectively. The mean usual micronutrient intakes were below the estimated average requirements for all micronutrients, with the exception of vitamin C and Zn. The MPA across eleven micronutrients was 0·19 (sd 0·16). The diet was found to be monotonous (MDDS was 3·9 (sd 1·0)) and rice contributed to about 60 % of the energy intake. The multiple regression analyses showed that MPA was positively associated with energy intake, dietary diversity, women's educational level and socio-economic status, and was higher in the winter.

CONCLUSIONS

The low micronutrient intakes are probably explained by low dietary diversity and a low intake of micronutrient-rich foods.
