The Cost of Canine Rabies on Four Continents

We estimated the economic impacts of canine rabies in Latin America, Africa and Asia. Direct and indirect costs of rabies post‐exposure prophylaxis, dog vaccination and control, rabies diagnostic testing and cattle mortality‐related costs were accounted for. The number of human deaths was updated from previous estimates based on population growth, and the costs associated with the risk of human mortality were incorporated. We accounted for uncertainty associated with the parameter estimates using a Monte Carlo simulation and estimated that the global burden of canine rabies is approximately $124 billion annually. This result illustrates the potential benefits that could be realized if canine rabies was eliminated and provides an important benchmark against which the cost of any potential elimination campaign can be compared.     

An Analysis of the Development of Colonic Diverticulosis in the Japanese

PURPOSE There are quite different characteristics between colonic diverticulosis in the West and that in Asia, including Japan. These differences include the predominance of a few diverticula over others, right-sidedness, young generation, male, and few complications. In Japan, colonic diverticulosis started increasing in the 1970s. This study was performed to obtain exact evidence of diverticular development in contemporary Japanese by observing changes in diverticula in the same individuals examined over a period of ten or more years. METHODS This study included 82 subjects (56 (68 percent) males and 26 (32 percent) females) who underwent barium enema examinations repeatedly for more than ten years from 1982 to 2000. The diverticula were categorized according to their location in the colon: right, left, or bilateral. They were also categorized by whether they appeared individually, were scattered with two to nine diverticula, or were numerous with ten or more diverticula. RESULTS At the beginning of observation, the most frequent location was the right side (55; 67 percent), followed by bilateral (20; 24 percent) and the left side (7; 9 percent). Ten or more years later, the number on the right side had decreased to 39 (48 percent). The number of bilateral diverticula had increased to 38 (46 percent), and the number on the left had barely changed, to 5 (6 percent). The number of diverticula increased from 253 to 604 (239 percent) in the right and from 380 to 929 (244 percent) in the bilateral. The initially very small number in the left increased from 9 to 48 (533 percent). The data show marked increases in the right and bilateral diverticula, and also the spread from the right side to the left side. CONCLUSION In contemporary Japanese, although the right predominated initially, diverticulosis showed a strong tendency to increase and spread from the right to the bilateral. The number of bilateral diverticula also tended to increase. The left did not change much.

Diagnosing peripheral neuropathy in South‐East Asia: A focus on diabetic neuropathy

Burning and stabbing pain in the feet and lower limbs can have a significant impact on the activities of daily living, including walking, climbing stairs and sleeping. Peripheral neuropathy in particular is often misdiagnosed or underdiagnosed because of a lack of awareness amongst both patients and physicians. Furthermore, crude screening tools, such as the 10‐g monofilament, only detect advanced neuropathy and a normal test will lead to false reassurance of those with small fiber mediated painful neuropathy. The underestimation of peripheral neuropathy is highly prevalent in the South‐East Asia region due to a lack of consensus guidance on routine screening and diagnostic pathways. Although neuropathy as a result of diabetes is the most common cause in the region, other causes due to infections (human immunodeficiency virus, hepatitis B or C virus), chronic inflammatory demyelinating polyneuropathy, drug‐induced neuropathy (cancer chemotherapy, antiretrovirals and antituberculous drugs) and vitamin deficiencies (vitamin B₁, B₆, B₁₂, D) should be actively excluded.     

Correlates of sedentary behaviour in Asian adults: A systematic review

The objective of this study is to systematically review the evidence on correlates of sedentary behaviour (SB) among Asian adults. We searched for studies that examined individual, environmental, and political/cultural correlates of total and domain‐specific SB (transport, occupation, leisure, and screen time) in Asian adults published from 2000 onwards in nine scientific databases. Two reviewers independently screened identified references. Following quality assessment of included studies, we performed narrative synthesis that considered differences based on SB measurements, regions, and population characteristics (PROSPERO: CRD42018095268). We identified 13 249 papers of which we included 49, from four regions and 12 countries. Researchers conducted cross‐sectional analyses and most relied on SB self‐report for SB measurement. Of the 118 correlates studied, the following associations were consistent: higher age, living in an urban area (East Asia), and lower mental health with higher total SB; higher education with higher total and occupational SB; higher income with higher leisure‐time SB; higher transit density with higher total SB in older East Asians; and being an unmarried women with higher SB in the Middle East. We encourage more research in non‐high‐income countries across regions, further exploration of important but neglected correlates using longitudinal designs and qualitative research, and the use of objective instruments to collect SB data.     

The HOPE Asia Network activity for “zero” cardiovascular events in Asia: Overview 2020

The impact of hypertension‐related cardiovascular disease and target organ damage, and therefore the benefits of blood pressure (BP) control, is greater in Asian than in Western countries. Asia‐specific features of hypertension and its effective management are important and active areas of research. The Hypertension Cardiovascular Outcome Prevention and Evidence in Asia (HOPE Asia) Network was formed in 2016 and is now a member of the World Hypertension League. The main goal of the HOPE Asia Network is to improve the management of hypertension and organ protection toward achieving “zero” cardiovascular events in Asia. Considerable work has already been done on the journey to achieving this goal. We have shown that BP control status in Asia differs between countries, and even between regions within the same country. Several expert panel consensus recommendations and clinical guidance papers are available to support the use of home and ambulatory BP monitoring in the region. In addition, the AsiaBP@Home study prospectively investigated home BP control status across 15 specialist centers using the same validated device and measurement schedule. We have also proposed the concept of systemic hemodynamic atherothrombotic syndrome (SHATS), a vicious cycle of BP variability and vascular disease on cardiovascular events and organ damage, and suggested a SHATS score for risk stratification for clinical practice. This special issue of the journal collates Asia‐specific resources and data, contributing to advances in hypertension management and cardiovascular disease prevention in the region.     

An overview of hypertension and cardiac involvement in Asia: Focus on heart failure

Cardiovascular Disease (CVD) is the leading cause of deaths worldwide, contributing to about 30% of all deaths. Half of the cases of CVD are estimated in Asia, the world's most populous continent. Hypertension, a major modifiable risk factor for CVD, results in more deaths than any other CV risk factors in the Asian regions. The total number of patients with hypertension is likely to grow as the population ages. The proportion of the elderly population aged 65 years or more in Asia is expected to increase from 7.4% in 2015 to 10.9% in 2030. It is important to note that more than half (54%) of the world's population live in Asia. Aside of being the biggest single risk factor for global deaths, hypertension is also an important precursor and most common risk factor of heart failure (HF). An increase in HF prevalence is clearly related to the rapid epidemiological transition caused by changes in lifestyle in Asian countries. However, the availability of data on HF burden and health care delivery is limited in Asia compared with Europe and North America. This reality has driven the working group of Asian experts for example the HOPE Asia Network to concentrate on hypertension as risk factors for CVD, with the mission to improve the management of hypertension resulting in organ protection toward a goal of achieving “ZERO” CV event in Asia. This paper aims to give an overview regarding the heart problems caused by hypertension in Asia, focus on HF.     

Diversity of and initiatives for hypertension management in Asia—Why we need the HOPE Asia Network

The Hypertension Cardiovascular Outcome Prevention and Evidence in Asia (HOPE Asia) Network was set up to improve the management of hypertension in Asia with the ultimate goal of achieving “zero” cardiovascular events. Asia is a diverse continent, and the prevalence of hypertension has increased over the last 30 years. There are a number of Asia‐specific features of hypertension and hypertension‐related cardiovascular complications, which means that a region‐specific approach is needed. White‐coat hypertension will become more of an issue over time as Asian populations age, and masked hypertension is more prevalent in Asian than in Western countries. Identifying and treating masked hypertension is important to reduce cardiovascular risk. Abnormal patterns of blood pressure (BP) variability common in Asia include exaggerated early morning BP surge and nocturnal hypertension. These are also important cardiovascular risk factors that need to be managed. Home blood pressure monitoring (HBPM) is an important tool for detecting white‐coat and masked hypertension, and monitoring BP variability, and practices in Asia are variable. Use of HBPM is important given the Asia‐specific features of hypertension, and strategies are needed to improve and standardize HBPM usage. Development of HBPM devices capable of measuring nocturnal BP along with other information and communication technology‐based strategies are key developments in the widespread implementation of anticipation medicine strategies to detect and prevent cardiovascular events in patients with hypertension. Region‐wide differences in hypertension prevalence, control, and management practices in Asia highlight the importance of information sharing to facilitate best practices.     

Asian management of hypertension: Current status,home blood pressure,and specific concerns in China

Increasing life expectancy in the population means that the prevalence of hypertension in China will increase over the coming decades. Although awareness and control rates have improved, the absolute rates remain unacceptably low. Cardiovascular disease (CVD) is the biggest killer in China, and sharp increases in the prevalence of CVD risk factors associated with rapid lifestyle changes will contribute to ongoing morbidity and mortality. This highlights the importance of effectively diagnosing and managing hypertension, where home blood pressure monitoring (HBPM) has an important role. Use of HBPM in China is increasing, particularly now that Asia‐specific guidance is available, and this out‐of‐office BP monitoring tool will become increasingly important over time. To implement these recommendations and guidelines, a Web‐based and WeChat‐linked nationwide BP measurement system is being established in China. Local guidelines state that both HBPM and ambulatory blood pressure monitoring should be implemented where available. In China, hypertension is managed most often using calcium channel blockers, followed by angiotensin receptor blockers or angiotensin‐converting enzyme inhibitors. Key barriers to hypertension control in China are low awareness and control rates.     

Epilepsy: Asia versus Africa

Is epilepsy truly an “African ailment”? We aimed to determine this, since international health agencies often refer to epilepsy as an African disease and the scientific literature has spoken the same tone. Various published materials, mainly reports, articles, were used to gather Asian and African evidence on various aspects of epilepsy and many of its risk and associated factors. Our results suggest that in no way can epilepsy be considered as an African ailment and such characterization is most likely based on popular beliefs rather than scientific evidence. In comparison to Africa, Asia has a 5.0% greater burden from all diseases, and is 17.0% more affected from neuropsychiatric disorders (that include epilepsy). Given that more countries in Asia are transitioning, there may be large demographic and lifestyle changes in the near future. However these changes are nowhere close to those expected in Africa. Moreover, 23 million Asians have epilepsy in comparison to 3.3 million Africans and 1.2 million sub‐Saharan Africans. In comparison to Africa, Asia has more untreated patients, 55.0% more additional epilepsy cases every year, because of its larger population, with greater treatment cost and possibly higher premature mortality. Of several associated factors discussed herein, many have more importance for Asia than Africa. The current state of epilepsy in Asia is far less than ideal and there is an urgent need to recognize and accept the importance of epilepsy in Asia. In no way can epilepsy be considered as an African ailment. This is most likely based on popular beliefs rather than scientific evidence.
