Trends in Coronary Heart Disease Epidemiology in India.

Abstract: Cardiovascular diseases, especially coronary heart disease (CHD), are epidemic in India. The Registrar General of India reported that CHD led to 17% of total deaths and 26% of adult deaths in 2001-2003, which increased to 23% of total and 32% of adult deaths in 2010-2013. The World Health Organization (WHO) and Global Burden of Disease Study also have highlighted increasing trends in years of life lost (YLLs) and disability-adjusted life years (DALYs) from CHD in India. In India, studies have reported increasing CHD prevalence over the last 60 years, from 1% to 9%-10% in urban populations and <1% to 4%-6% in rural populations. Using more stringent criteria (clinical ± Q waves), the prevalence varies from 1%-2% in rural populations and 2%-4% in urban populations. This may be a more realistic prevalence of CHD in India. Case-control studies have reported that important risk factors for CHD in India are dyslipidemias, smoking, diabetes, hypertension, abdominal obesity, psychosocial stress, unhealthy diet, and physical inactivity. Suitable preventive strategies are required to combat this epidemic.

Epidemiology of and Risk Factors for Type 2 Diabetes in Egypt

Abstract: Background Diabetes is a fast-growing health problem in Egypt with a significant impact on morbidity, mortality, and health care resources. Currently, the prevalence of type 2 diabetes (T2D) in Egypt is around 15.6% of all adults aged 20 to 79. Objective To describe the epidemiology, principal causes, associated risk factors, cultural aspects, and challenges that may contribute to the rapid rise in T2D in Egypt. Methods Review of papers in PubMed and relevant gray literature. Findings The International Diabetes Federation (IDF) has identified Egypt as the ninth leading country in the world for the number of patients with T2D. The prevalence of T2D in Egypt was almost tripled over the last 2 decades. This sharp rise could be attributed to either an increased pattern of the traditional risk factors for T2D such as obesity and physical inactivity and change in eating pattern or other risk factors unique to Egypt. These include increased exposure to environmental risk factors like pesticides and increased prevalence of chronic hepatitis C. Conclusions Prevention, early identification, and effective intervention are integral components of effective T2D care in Egypt. These strategies may reduce the expanding economic burden associated with T2D care.

Effects of Environmental Exposures on Fetal and Childhood Growth Trajectories.

Abstract: Delayed fetal growth and adverse birth outcomes are some of the greatest public health threats to this generation of children worldwide because these conditions are major determinants of mortality, morbidity, and disability in infancy and childhood and are also associated with diseases in adult life. A number of studies have investigated the impacts of a range of environmental conditions during pregnancy (including air pollution, endocrine disruptors, persistent organic pollutants, heavy metals) on fetal and child development. The results, while provocative, have been largely inconsistent. This review summarizes up to date epidemiologic studies linking major environmental pollutants to fetal and child development and suggested future directions for further investigation.

Hypertension and Related Cardiovascular Disease Burden in China

Abstract: Background With rapid economic development, urbanization, and an aging population, cardiovascular diseases (CVDs) have become the leading cause of death in China. Objectives The aim of this study was to provide a comprehensive review on the prevalence, awareness, treatment, and control of hypertension (HTN) as well as blood pressure (BP)-related morbidity and mortality of CVD in Chinese adults over time. Findings The prevalence of HTN in China is high and increasing. Recent estimates are variable but indicate 33.6% (35.3% in men and 32% in women) or 335.8 million (178.6 million men and 157.2 million women) of the Chinese adult population had HTN in 2010, which represents a significant increase from previous surveys. BP-related CVD remains the leading cause of death in Chinese adults, with stroke being the predominant cause of cardiovascular deaths. Of those with HTN, 33.4% (30.4% in men and 36.7% in women) were aware of their condition, 23.9% (20.6% in men and 27.7% in women) were treated, and only 3.9% (3.5% in men and 4.3% in women) were controlled to the currently recommended target of BP Conclusions The prevalence of HTN is high and increasing, while the control rate is low in Chinese adults. Combatting HTN and BP-related morbidity and mortality will require a comprehensive approach at national and local levels. The major challenge moving forward is to develop and implement effective, practical, and sustainable prevention and treatment strategies in China.

Treatment and Prevention of Pandemic H1N1 Influenza

Abstract: Background Swine influenza is a respiratory infection common to pigs worldwide caused by type A influenza viruses, principally subtypes H1N1, H1N2, H2N1, H3N1, H3N2, and H2N3. Swine influenza viruses also can cause moderate to severe illness in humans and affect persons of all age groups. People in close contact with swine are at especially high risk. Until recently, epidemiological study of influenza was limited to resource-rich countries. The World Health Organization declared an H1N1 pandemic on June 11, 2009, after more than 70 countries reported 30,000 cases of H1N1 infection. In 2015, incidence of swine influenza increased substantially to reach a 5-year high. In India in 2015, 10,000 cases of swine influenza were reported with 774 deaths. Methods The Centers for Disease Control and Prevention recommend real-time polymerase chain reaction as the method of choice for diagnosing H1N1. Antiviral drugs are the mainstay of clinical treatment of swine influenza and can make the illness milder and enable the patient to feel better faster. Findings Antiviral drugs are most effective when they are started within the first 48 hours after the clinical signs begin, although they also may be used in severe or high-risk cases first seen after this time. The Centers for Disease Control and Prevention recommends use of oseltamivir (Tamiflu, Genentech) or zanamivir (Relenza, GlaxoSmithKline). Conclusion Prevention of swine influenza has 3 components: prevention in swine, prevention of transmission to humans, and prevention of its spread among humans. Because of limited treatment options, high risk for secondary infection, and frequent need for intensive care of individuals with H1N1 pneumonia, environmental control, including vaccination of high-risk populations and public education are critical to control of swine influenza out breaks.

Diabetes Care in Malaysia: Problems, New Models, and Solutions

Abstract: Background Diabetes is a major public health concern in Malaysia, and the prevalence of type 2 diabetes (T2D) has escalated to 20.8% in adults above the age of 30, affecting 2.8 million individuals. The burden of managing diabetes falls on primary and tertiary health care providers operating in various settings. Objectives This review focuses on the current status of diabetes in Malaysia, including epidemiology, complications, lifestyle, and pharmacologic treatments, as well as the use of technologies in its management and the adoption of the World Health Organization chronic care model in primary care clinics. Methods A narrative review based on local available health care data, publications, and observations from clinic experience. Findings The prevalence of diabetes varies among the major ethnic groups in Malaysia, with Asian Indians having the highest prevalence of T2D, followed by Malays and Chinese. The increase prevalence of overweight and obesity has accompanied the rise in T2D. Multidisciplinary care is available in tertiary and primary care settings with integration of pharmacotherapy, diet, and lifestyle changes. Poor dietary adherence, high consumption of carbohydrates, and sedentary lifestyle are prevalent in patients with T2D. The latest medication options are available with increasing use of intensive insulin regimens, insulin pumps, and continuous glucose monitoring systems for managing glycemic control. A stepwise approach is proposed to expand the chronic care model into an Innovative Care for Chronic Conditions framework to facilitate implementation and realize better outcomes in primary care settings. Conclusions A comprehensive strategy and approach has been established by the Malaysian government to improve prevention, treatment, and control of diabetes as an urgent response to this growing chronic disease.

Diabetes Care in India

Abstract: Background Diabetes has become a major health care problem in India with an estimated 66.8 million people suffering from the condition, representing the largest number of any country in the world. Objective The rising burden of diabetes has greatly affected the health care sector and economy in India. The goal of health care experts in India is to transform India into a diabetes care capital in the world. Methods An expert detailed review of the medical literature with an Asian Indian context was performed. Findings Recent epidemiologic studies from India point to a great burden from diabetes. Diabetes control in India is far from ideal with a mean hemoglobin A1c of 9.0%—at least 2.0% higher than suggested by international bodies. Nearly half of people with diabetes remain undetected, accounting for complications at the time of diagnosis. Screening can differentiate an asymptomatic individual at high risk from one at low risk for diabetes. Despite the large number of people with diabetes in India, awareness is low and needs to be addressed. Other challenges include balancing the need for glycemic control with risk reduction due to overly tight control, especially in high-risk groups and taking into account health care professional expertise, attitudes, and perceptions. Pharmacologic care should be individualized with early consideration of combination therapy. Regular exercise, yoga, mindful eating, and stress management form a cornerstone in the management of diabetes. Conclusions Considering the high cost incurred at various steps of screening, diagnosis, monitoring, and management, it is important to realize the cost-effective measures of diabetes care that are necessary to implement. Result-oriented organized programs involving patient education, as well as updating the medical fraternity on various developments in the management of diabetes, are required to combat the current diabetes epidemic in India.

Expanding the Role of Nurses to Improve Hypertension Care and Control Globally

Abstract: The role of the nurse in improving hypertension control has expanded over the past 50 years, complementing and supplementing that of the physician. Nurses' involvement began with measuring and monitoring blood pressure (BP) and patient education and has expanded to become one of the most effective strategies to improve BP control. Today the roles of nurses and nurse practitioners (NPs) in hypertension management involve all aspects of care, including (1) detection, referral, and follow up; (2) diagnostics and medication management; (3) patient education, counseling, and skill building; (4) coordination of care; (5) clinic or office management; (6) population health management; and (7) performance measurement and quality improvement. The patient-centered, multidisciplinary team is a key feature of effective care models that have been found to improve care processes and control rates. In addition to their clinical roles, nurses lead clinic and community-based research to improve the hypertension quality gap and ethnic disparities by holistically examining social, cultural, economic, and behavioral determinants of hypertension outcomes and designing culturally sensitive interventions to address these determinants.

Diabetes Care in Nigeria

Abstract: Background Diabetes is a noncommunicable disease that has attained great significance in the sub-Saharan region, with Nigeria being the most affected. Many persons with the condition suffer a reduced life expectancy and quality of life. Diabetes places an extra burden on the individuals and families affected, especially for the majority of patients unable to access quality health care. Objective To describe the elements of diabetes management in Nigeria, areas for improvement, and proposed strategies to optimize care. Methods A systematic literature search was performed on diabetes in Nigeria. Local and nonindexed literature, PubMed, and Google Scholar were used to source information on the subject. Findings Diabetes-related morbidity and mortality continue to increase due to population expansion, urban migration, declining physical activity, and dietary factors. The organization of diabetes care is poorly coordinated, especially at the primary and secondary tiers of the public health care system, with consequent poor outcomes. Thus life expectancy (just about 50 years), which is low in the region, is further reduced by the double jeopardy of communicable (eg, tuberculosis, HIV/AIDS, and malaria) and noncommunicable diseases, such as diabetes and its closely related comorbidity, hypertension. Conclusions The way forward is to improve maternal and child care, promote screening of at-risk populations, and develop strategies for primary prevention and early intervention to optimize glycemic control. Greater commitment to health care by the government and nongovernmental organizations and greater awareness by Nigerians should facilitate the desired improvements in disease prevention and glycemic control in those who are already affected.

Diabetes Care in Iran: Where We Stand and Where We Are Headed

Abstract: Background The prevalence of diabetes has steadily increased in Iran from the time of the first published nationally representative survey in 1999 and despite efforts and strategies to reduce disease burden. Objectives The aim of the present review was to describe the current status of diabetes care in Iran. Methods A selective review of the relevant literature, focusing on properly conducted studies, describing past and present diabetes care strategies, policies, and outcomes in Iran was performed. Findings The quality of diabetes care has gradually improved as suggested by a reduction in the proportion of undiagnosed patients and an increase in affordability of diabetes medications. The National Program for Prevention and Control of Diabetes has proven successful at identifying high-risk individuals, particularly in rural and remote-access areas. Unfortunately, the rising tide of diabetes is outpacing these efforts by a considerable margin. Conclusions Substantial opportunities and challenges in the areas of prevention, diagnosis, and management of diabetes exist in Iran that need to be addressed to further improve the quality of care and clinical outcomes.

Health Consequences of Environmental Exposures: Changing Global Patterns of Exposure and Disease.

Abstract: Environmental pollution is a major cause of disease and death. Exposures in early life are especially dangerous. Patterns of exposure vary greatly across countries. In low-income and lower middle income countries (LMICs), infectious, maternal, neonatal, and nutritional diseases are still major contributors to disease burden. By contrast, in upper middle income and high-income countries noncommunicable diseases predominate. To examine patterns of environmental exposure and disease and to relate these patterns to levels of income and development, we obtained publically available data in 12 countries at different levels of development through a global network of World Health Organization Collaborating Centres in Children's Environmental Health. Pollution exposures in early life contribute to both patterns. Chemical and pesticide pollution are increasing, especially in LMICs. Hazardous wastes, including electronic waste, are accumulating. Pollution-related chronic diseases are becoming epidemic. Future Global Burden of Disease estimates must pay increased attention to the short- and long-term consequences of environmental pollution.

Health Consequences of Environmental Exposures: Causal Thinking in Global Environmental Epidemiology

Abstract: The 2010 Global Burden of Disease estimates indicate a trend toward increasing years lived with disability from chronic noncommunicable diseases (NCDs). Risk factors examined included smoking, diet, alcohol, drug abuse, and physical inactivity. By contrast, little consideration was given to accumulating evidence that exposures to environmental chemicals, psychosocial stress, and malnutrition during fetal development and across the life span also increase risk of NCDs. To address this gap, we undertook a narrative review of early-life environmental contributions to disease. We documented numerous etiologic associations. We propose that future GBD estimates use an expanded approach for assessing etiologic contributions of environmental exposures to recognized disease risk factors. We argue that broadening the definition of environmental disease, together with improved methods of assessing early life exposures and their health outcomes across the life span, will allow better understanding of causal associations and provide the incentives required to support strategies to control avoidable exposures and reduce disease risk.

Early-life Exposure to Widespread Environmental Toxicants and Health Risk: A Focus on the Immune and Respiratory Systems

Abstract: Evidence has accumulated that exposure to widespread environmental toxicants, such as heavy metals, persistent organic pollutants, and tobacco smoke adversely affect fetal development and organ maturation, even after birth. The developing immune and respiratory systems are more sensitive to environmental toxicants due to their long-term physical development, starting from the early embryonic stage and persisting into early postnatal life, which requires complex signaling pathways that control proliferation and differentiation of highly heterogeneous cell types. In this review, we summarize the effect of early-life exposure to several widespread environmental toxicants on immune and lung development before and after birth, including the effects on immune cell counts, baseline characteristics of cell-mediated and humoral immunity, and alteration of lung structure and function in offspring. We also review evidence supporting the association between early-life exposure to environmental toxicants and risk for immune-related diseases and lung dysfunction in offspring in later life.

Global/Local: What Does It Mean for Global Health Educators and How Do We Do It?

Abstract: Background There has been dramatic growth in the number of innovative university programs that focus on social justice and teach community-based strategies that are applicable both domestically in North America and internationally. These programs often are referred to as global/local and reflect an effort to link global health and campus community engagement efforts to acknowledge that a common set of transferable skills can be adapted to work with vulnerable populations wherever they may be. However, the concepts underlying global/local education are undertheorized and universities struggle to make the global/local link without a conceptual framework to guide them in this pursuit.

The Global Health Dimensions of Asbestos and Asbestos-Related Diseases.

Abstract: The Collegium Ramazzini (CR) reaffirms its long-standing position that responsible public health action is to ban all extraction and use of asbestos, including chrysotile. This current statement updates earlier statements by the CR with a focus on global health dimensions of asbestos and asbestos-related diseases (ARDs). The ARD epidemic will likely not peak for at least a decade in most industrialized countries and for several decades in industrializing countries. Asbestos and ARDs will continue to present challenges in the arena of occupational medicine and public health, as well as in clinical research and practice, and have thus emerged as a global health issue. Industrialized countries that have already gone through the transition to an asbestos ban have learned lessons and acquired know-how and capacity that could be of great value if deployed in industrializing countries embarking on the transition. The accumulated wealth of experience and technologies in industrialized countries should thus be shared internationally through global campaigns to eliminate ARDs.

E-Waste Informal Recycling: An Emerging Source of Lead Exposure in South America

Abstract: Background Primitive electronic waste (e-waste) recycling creates exposures to several hazardous substances including lead. In Uruguay, primitive recycling procedures are a significant source of lead exposure. Objectives The aim of this study was to examine lead exposure in blood lead levels (BLLs) in low-income children exposed to lead through burning cables. Methods A sample of children and adolescents exposed to lead through burning cable activities were assessed at the Department of Toxicology in Montevideo, Uruguay, between 2010 and 2014. Soil lead levels of residences were taken shortly after their assessment. Findings The final sample included 69 children and adolescents (mean age 7.89 years). More than 66% of participants had an additional source of lead exposure—manual gathering of metals—and Conclusion Among children exposed to e-waste recycling, the most common additional source of lead exposure was the manual gathering of metals. The average BLL among children and adolescents in this study is higher than the BLLs currently suggested in medical intervention. Future research should focus on exploring effective interventions to reduce lead exposure among this vulnerable group.

Knowledge, Attitude, and Practices Regarding Vector-borne Diseases in Western Jamaica

Abstract: Background Outbreaks of vector-borne diseases (VBDs) such as dengue and malaria can overwhelm health systems in resource-poor countries. Environmental management strategies that reduce or eliminate vector breeding sites combined with improved personal prevention strategies can help to significantly reduce transmission of these infections. Objective The aim of this study was to assess the knowledge, attitudes, and practices (KAPs) of residents in western Jamaica regarding control of mosquito vectors and protection from mosquito bites. Methods A cross-sectional study was conducted between May and August 2010 among patients or family members of patients waiting to be seen at hospitals in western Jamaica. Participants completed an interviewer-administered questionnaire on sociodemographic factors and KAPs regarding VBDs. KAP scores were calculated and categorized as high or low based on the number of correct or positive responses. Logistic regression analyses were conducted to identify predictors of KAP and linear regression analysis conducted to determine if knowledge and attitude scores predicted practice scores. Findings In all, 361 (85 men and 276 women) people participated in the study. Most participants (87%) scored low on knowledge and practice items (78%). Conversely, 78% scored high on attitude items. By multivariate logistic regression, housewives were 82% less likely than laborers to have high attitude scores; homeowners were 65% less likely than renters to have high attitude scores. Participants from households with 1 to 2 children were 3.4 times more likely to have high attitude scores compared with those from households with no children. Participants from households with at least 5 people were 65% less likely than those from households with fewer than 5 people to have high practice scores. By multivariable linear regression knowledge and attitude scores were significant predictors of practice score. Conclusion The study revealed poor knowledge of VBDs and poor prevention practices among participants. It identified specific groups that can be targeted with vector control and personal protection interventions to decrease transmission of the infections.

Diabetes Care in the Philippines

Abstract: Background Diabetes is increasing at an alarming rate in Asian countries including the Philippines. Both the prevalence and incidence of type 2 diabetes (T2D) continue to increase with a commensurate upward trend in the prevalence of prediabetes. Objectives The aim of this study was to review the prevalence of diabetes in the Philippines and to describe extensively the characteristics of diabetes care in the Philippines from availability of diagnostics tests to the procurement of medications. Methods A literature search was performed using the search words diabetes care and Philippines. Articles that were retrieved were reviewed for relevance and then synthesized to highlight key features. Findings The prevalence of diabetes in the Philippines is increasing. Rapid urbanization with increasing dependence on electronic gadgets and sedentary lifestyle contribute significantly to this epidemic. Diabetes care in the Philippines is disadvantaged and challenged with respect to resources, government support, and economics. The national insurance system does not cover comprehensive diabetes care in a preventive model and private insurance companies only offer limited diabetes coverage. Thus, most patients rely on “out-of-pocket” expenses, namely, laboratory procedures and daily medications. Consequently, poor pharmacotherapy adherence impairs prevention of complications. Moreover, behavioral modifications are difficult due to cultural preferences for a traditional diet of refined sugar, including white rice and bread. Conclusions Translating clinical data into practice in the Philippines will require fundamental and transformative changes that increase diabetes awareness, emphasize lifestyle change while respecting cultural preferences, and promote public policy especially regarding the health insurance system to improve overall diabetes care and outcomes.

Global Variation of Human Papillomavirus Genotypes and Selected Genes Involved in Cervical Malignancies.

Abstract: Background Carcinoma of the cervix is ranked second among the top 5 cancers affecting women globally. Parallel to other cancers, it is also a complex disease involving numerous factors such as human papillomavirus (HPV) infection followed by the activity of oncogenes and environmental factors. The incidence rate of the disease remains high in developing countries due to lack of awareness, followed by mass screening programs, various socioeconomic issues, and low usage of preventive vaccines. Over the past 3 decades, extensive research has taken place in cervical malignancy to elucidate the role of host genes in the pathogenesis of the disease, yet it remains one of the most prevalent diseases. It is imperative that recent genome-wide techniques be used to determine whether carcinogenesis of oncogenes is associated with cervical cancer at the molecular level and to translate that knowledge into developing diagnostic and therapeutic tools. Objective The aim of this study was to discuss HPV predominance with their genotype distribution worldwide, and in India, as well as to discuss the newly identified oncogenes related to cervical cancer in current scenario. Findings Using data from various databases and robust technologies, oncogenes associated with cervical malignancies were identified and are explained in concise manner. Conclusion Due to the advent of recent technologies, new candidate genes are explored and can be used as precise biomarkers for screening and developing drug targets.

Paraoxonase-1 and Early-Life Environmental Exposures

Abstract: Acute and chronic exposures to widely used organophosphorus (OP) insecticides are common. Children's detoxification mechanisms are not well developed until several years after birth. The increased cases of neurodevelopmental disorders in children, together with their increased susceptibility to OP neurotoxicity cannot be explained by genetic factors alone but could be related to gene-environment interactions. Paraoxonase-1 (PON1) is an enzyme that can detoxify OPs but its catalytic efficiency for hydrolysis to certain OPs is modulated by the Q192R polymorphism. Studies with animals have provided important information on the role of PON1 in protecting against gestational and postnatal toxicity to OPs. The PON1Q192 allele is less efficient in hydrolyzing certain OPs than the PON1R192 allele. Maternal PON1 status (PON1 activity levels, the most important measurement, and functional Q192R phenotype) modulates the detrimental effects of exposure to the OP chlorpyrifos oxon on fetal brain gene expression and biomarkers of exposure. Epidemiologic studies suggest that children from mothers with lower PON1 status who were in contact with OPs during pregnancy tend to show smaller head circumference at birth and adverse effects in cognitive function during childhood. Infants and children are vulnerable to OP toxicity. The detrimental consequences of OPs on neurodevelopment can lead to future generations with permanent cognitive problems and susceptibility to develop neurodegenerative diseases. Improved methods using mass spectrometry to monitor OP-adducted biomarker proteins are needed and will be extremely helpful in early life biomonitoring, while measurement of PON1 status as a biomarker of susceptibility will help identify mothers and children highly sensitive to OPs. The use of adductomics instead of enzymatic activity assays for biomonitoring OP exposures have proved to provide several advantages, including the use of dried blood spots, which would facilitate monitoring newborn babies and children.

Diabetes in Vietnam

Abstract: Background The prevalence for diabetes, prediabetes, and gestational diabetes in Vietnam are low relative to other parts of the world, but they are increasing at alarming rates. These changes have occurred in the setting of economic and cultural transitions. Objectives The aim of this study was to provide relevant information depicting the diabetes burden in Vietnam. Methods Literature was reviewed using PubMed and local Vietnamese sources, including papers published in the Vietnamese language. Findings In 2012, the prevalence of diabetes was 5.4% and prediabetes 13.7%. In 2005, the prevalence of obesity was 1.7%. There is a dual burden of over- and undernutrition observed in Vietnam. Diabetes is associated with an increased waist-to-hip ratio despite normal body mass index. Nutritional transitions occurred with increased protein, fat, and fast foods, and with decreased fresh fruits and vegetables. Tobacco use is very high in Vietnam with 66% of adult men currently smoking. Challenges include endocrinology training, health care coverage, patient education, and lack of coordination among government and specialist agencies. Conclusion Diabetes is a growing problem in Vietnam and is associated with obesity, changes in dietary patterns, and other cultural transitions. More research is needed to better understand this health care problem and to devise targeted interventions.

Hypertension in Canada: Past, Present, and Future.

Abstract: Canada has an extremely successful hypertension detection and treatment program. The aim of this review was to highlight the historic and current infrastructure and initiatives that have led to this success, and the outlook moving forward into the future. We discuss the evolution of hypertension awareness and control in Canada; contributions made by organizations such as the Canadian Hypertension Society, Blood Pressure Canada, and the Canadian Hypertension Education Program; the amalgamation of these organizations into Hypertension Canada; and the impact that Hypertension Canada has had on hypertension care in Canada. The important contribution that public policy and advocacy can have on prevention and control of blood pressure in Canada is described. We also highlight the importance of population-based strategies, health care access and organization, and accurate blood pressure measurement (including ambulatory, home, and automated office modalities) in optimizing hypertension prevention and management. We end by discussing how Hypertension Canada will move forward in the near and longer term to address the unmet residual risk attributable to hypertension and associated cardiovascular risk factors. Hypertension Canada will continue to strive to enhance hypertension prevention and control rates, thereby improving the quality of life and cardiovascular outcomes of Canadians, while at the same time creating a hypertension care model that can be emulated across the world.

Sodium Intake, Blood Pressure, and Dietary Sources of Sodium in an Adult South Indian Population.

Abstract: Background The association between prevalence of hypertension and its relationship with dietary sodium intake has never been published from large epidemiological studies in the South Indian population before. Objectives To assess sodium intake and its association with blood pressure, and major dietary sources of sodium in an adult population in southeastern India. Methods This study included a representative population-based sample of 8080 individuals (57% women) >20 years of age. Individuals with previous history of hypertension and outliers for sodium intake were excluded, resulting in a sample size of 6876, with 4269 from semi-urban/urban and 2607 from rural areas. Baseline measurements included evaluation of systolic (SBP) and diastolic (DBP) blood pressures, anthropometric, sociodemographic, and psychosocial parameters. Based on 24-hour recall, we calculated total daily sodium intake and the percentage contributed by each food group to the total sodium intake. Participants were assigned based on quintiles of dietary sodium intake. Mixed-effects multivariable linear regression models assessed the association of SBP and DBP with sodium intake. Findings Men had higher mean sodium intake (4.1 ± 2 versus 3.2 ± 1.7 g/day; P Conclusion In a South Indian population, the dietary intake of sodium was higher than recommendations by major dietary guidelines and was an independent predictor of SBP.

A Systematic Review of Children's Environmental Health in Brazil.

Abstract: In the region of the Americas, approximately 100,000 children under the age of 5 years die each year due to environmental hazards. Brazil, due to its large size and wide range of environmental challenges, presents numerous hazards to children's health. The aim of this study was to systematically review the scientific literature that describes children's exposures to environmental pollutants in Brazil and their effects on Brazilian children's health. A systematic review of the scientific literature was performed without language restrictions and time of publication (years). The literature search was conducted in the following key resources: PubMed (MEDLINE), Scopus and Web of Science with the MeSH Terms: Environmental exposure AND Brazil (filters: Human, Child [birth to 18 years] and Affiliation Author). The Virtual Health Library was also employed to access the databases Scielo and Lilacs. The search strategy was [DeCS Terms]: Child OR adolescent AND Environmental exposure AND Brazil. Health effects in children associated with exposure to environmental pollutants in Brazil were reported in 74 studies, during the period between 1995 and 2015. The most frequently cited effect was hospital admission for respiratory causes including wheezing, asthma, and pneumonia among children living in areas with high concentrations of air pollutants. A broad spectrum of other health effects possibly linked to pollutants also was found such as prematurity, low birth weight, congenital abnormality (cryptorchidism, hypospadia, micropenis), poor performance in tests of psychomotor and mental development, and behavioral problems. Exposure to pesticides in utero and postnatally was associated with a high risk for leukemia in children <2 years old. These results show that there is a need in Brazil for stricter monitoring of pollutant emissions and for health surveillance programs especially among vulnerable populations such as pregnant women and young children.

Modern Management and Diagnosis of Hypertension in the United Kingdom: Home Care and Self-care.

Abstract: Background The effective diagnosis and management of hypertension is one of the most important parts of cardiovascular prevention internationally and this is no different in the United Kingdom. Approximately 14% of the UK population currently receive treatment for hypertension. Recent UK guidelines from the National Institute of Health and Care Excellence have placed greater emphasis on the utilization of out-of-office measurement of blood pressure to more accurately diagnose hypertension. Objective The aim of the present study was to provide a state-of-the-art review of the evidence for screening, diagnosing, and managing hypertension, as implemented in the United Kingdom, with an emphasis on the role of self-monitored and ambulatory blood pressure monitoring in routine clinical care. Method Consideration was given to the use of ambulatory and home monitoring to confirm a diagnosis of hypertension and the use of self-monitoring and self-management to monitor and guide treatment. The evidence for the use of self-monitoring in patients with hypertension was examined, both in isolation, and in combination with lifestyle and treatment interventions. Findings There is a place for self-monitored blood pressure in specific underresearched populations such as the elderly, specialist conditions, ethnic groups, and during pregnancy and this is discussed here. Conclusions The evidence supporting the use of out-of-office monitoring in all aspects of routine clinical care has increased substantially in recent years and is reflected in increased utilization by patients and clinicians alike. Several areas require further research but it is clear that out-of-office monitoring is here to stay and is fast becoming an important part of hypertension management in the United Kingdom.

The Impact of Early-Life Exposure to Air-borne Environmental Insults on the Function of the Airway Epithelium in Asthma

Abstract: The airway epithelium is both a physical barrier protecting the airways from environmental insults and a significant component of the innate immune response. There is growing evidence that exposure of the airway epithelium to environmental insults in early life may lead to permanent changes in structure and function that underlie the development of asthma. Here we review the current published evidence concerning the link between asthma and epithelial damage within the airways and identify gaps in knowledge for future studies.

Global Surgical Ecosystems: A Need for Systems Strengthening

Abstract: Background As surgery is gaining recognition as a critical component of universal health care worldwide, surgical communities have come together with unprecedented unity to advocate for systems to support surgical care. This community has long believed that much care could be performed in a cost-effective manner even in low resource settings, despite skepticism voiced by many in public health. To do so will require the development of new systems and re-vamping of old systems that are not effective. In the last five years, coalitions, expert panels, commissions, consortia and alliances have emerged to address these issues and there has been landmark success in advocacy with a new resolution at the 2015 World Health Assembly to include surgical care as a component of universal health coverage. It is critical to understand the ecosystem that constitutes the surgical environment. A surgical ecosystem could be described as a network of people, processes, and materials necessary for surgical services in the context of the facilities and environment in which it functions. Methods We describe components of a functioning surgical ecosystem in terms of administration, support staff and clinicians, and the necessary sub-systems for providing consumable materials such as anesthetic medication and suture and sterile instruments. Related systems that must be integrated are facilities and utilities such as electricity, lighting, plumbing and waste management and even laundry. But especially in low and middle income countries (LMICs) lack of any one of these may be rate-limiting. The World Health Organization (WHO) has developed situational analyses and checklists for first level district hospitals to identify missing elements. Conclusions A siloed approach cannot solve a systems problem. However, to scale up rapidly and to develop and sustain quality standards, a holistic “ecosystem” approach, including local and global professional societies and advocacy organizations will need to become engaged.

Diabetes Care in Republic of Macedonia: Challenges and Opportunities

Abstract: Background The Republic of Macedonia (RoM) has experienced a rapid rise in the prevalence of type 2 diabetes (T2D) over the past 2 decades, a period characterized by significant social, political, and economic change. RoM now has one of the highest rates of diabetes in Europe. Objectives To explore the modifiable conditions that may underlie and exacerbate the T2D epidemic; describe the state of diabetes care; and consider improved mechanisms for prevention and treatment, including research priorities, in RoM. Methods Methods included data mining from reliable sources and collaboration of authors to consider and describe applications of research from outside RoM and to identify evidence-based strategies to reduce the burden of T2D in RoM. Findings In 2014, the national prevalence of diabetes was 11.44% of the population (20-79 years) of RoM. Per capita caloric intake has increased significantly over the past 2 decades, with the majority of these calories coming from sugar, pork, chicken, beef, and sunflower oil. Excess calories, in the form of nutrient-deficient foods, animal products, and added oils promote insulin resistance and T2D. Tobacco use and lack of physical activity also contribute to the diabetes epidemic. Insulin, especially insulin analogues, are widely available and used to manage diabetes, often over other interventions that are more appropriate for patients with T2D, and more frequently than in other more developed countries, resulting in higher and unsustainable related costs. Conclusions A new National eHealth System allows for better identification and monitoring of citizens with diabetes. However, the rapidly growing expense of insulin in the past has been unsustainable. The potential exists for a stronger role for lifestyle interventions in prevention and treatment of T2D. Significant changes in dietary patterns parallel the rise in diabetes prevalence and are likely a leading cause of diabetes and its complications. Research in RoM is needed to determine the impact and acceptability of dietary interventions for prevention and treatment of T2D, as a first step toward reduction of diabetes prevalence and its complications and controlling spiraling health care costs.
