P025 GLOBAL, REGIONAL AND NATIONAL BURDEN OF HIGH SYSTOLIC BLOOD PRESSURE, 1990-2021: FINDINGS FROM THE GLOBAL BURDEN OF DISEASE STUDY 2021

High systolic blood pressure (SBP) is the leading preventable global health risk. As part of the Global Burden of Disease Study 2021, we quantify the SBP-associated burden (relative to a theoretical risk exposure level of 105-115 mmHg) among adults over 25, by age and sex, for 204 countries from 1990 to 2021. Standard GBD Bayesian methods were used to estimate SBP mean, standard deviation and corresponding distribution from 1,116 studies. Meta-analyses of 70 randomized controlled trials and cohorts were used to estimate the relative risks for seven outcomes: ischemic heart disease (IHD), stroke, chronic kidney disease (CKD), atrial fibrillation, aortic aneurysm, peripheral arterial disease (PAD) and hypertensive heart disease. Then, the population attributable fraction and SBP attributable burden were computed with 95% uncertainty intervals (UI). In 2021, 10.9 million deaths (9.2-12.5 million) and 225 million (190 - 259 million) disability-adjusted life years (DALYs) were attributable to elevated SBP worldwide, a decrease, since 1990, of 32% and 30% in age-standardized rates, respectively. In 2021, high SBP accounted for 7.8% of total DALYs; 49.9% (40.6 - 58.2%) of DALYs due to IHD; 57.3% (42.7-68.4%) due to stroke; 24.8% (13.0-36.1%) due to CKD; 30.1% (10.7-47.6%) due to atrial fibrillation; 17.1% (12.9-21.4%) due to aortic aneurysm; 13.0% (2.7-23.8%) due to PAD and 100% of the DALYs due to hypertensive heart disease. Globally, the burden attributable to SBP was higher in men than in women (3,162.9 [2,654.8-3,666.4] vs 2,167.3 [1857.4 -2510.9] age-standardized DALYs per 100,000). Age-standardized DALYs attributable to high SBP were highest in Central Asia and Eastern Europe, rates above six thousand per 100,000. The lowest levels were observed in high-income Asia Pacific, Australasia and Western Europe with less than 1000 DALYs per 100,000. Despite a decrease in age-standardized rates since 1990, high SBP remains a major global health risk with considerable regional variations. Targeted interventions are crucial to address these disparities and reduce SBP-related health impacts.

Efficacy and safety of methotrexate plus hydroxychloroquine combination therapy vs. methotrexate monotherapy in the treatment of rheumatoid arthritis: A randomized controlled clinical trial.

To explore the efficacy and safety of combination therapy with methotrexate (MTX) plus hydroxychloroquine (HCQ) vs. MTX monotherapy in patients with rheumatoid arthritis (RA). Sixty patients without prior RA treatments were randomly allocated in a 1:1 ratio to two groups: one receiving MTX plus HCQ, and the other receiving MTX monotherapy. We conducted a comparative analysis before and after the 12-week trial, evaluating the visual analogue scale (VAS), the disease activity score in 28 joints (DAS), serum inflammatory factor (including serum C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-α), as well as the outcome of the World Health Organization Quality of Life Brief Version questionnaire (WHOQOL-BREF) and the treatment-emergent adverse events (TEAEs) for all the participants in the study. At the 12th week of the trial, a more remarkable decrease in pain score (VAS), disease activity score (DAS), and serum inflammatory factor levels could be noticed in individuals on the combination therapy. The quality of life score was as well found to be higher in the MTX + HCQ group than the MTX monotherapy group. The incidence of adverse reactions in the MTX + HCQ and the MTX monotherapy groups were 10.00% and 6.67%, respectively. However, no statistical significance could be observed (p > .05). In our study, both the MTX + HCQ combination therapy and MTX monotherapy demonstrated improvements in symptoms, conditions and quality of life for patients with RA. Notably, the combination therapy could achieve better outcomes across all indices compared to MTX monotherapy, highlighting its potential as the optimal first-line treatment for RA. © 2024 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

Prevention of HIV/AIDS Transmission in Key Communities in Surabaya

Indonesia is in third place among Asia Pacific countries for the growth and spread of HIV with a total of 46,000 cases. East Java Province is designated as an area with concentrated HIV prevalence along with five other provinces, namely DKI Jakarta, Papua, Bali, Riau and West Java. Knowledge is one of the predisposing factors in early detection of HIV disease, as well as risky behavior that can cause HIV AIDS transmission. This research aims to provide education to key communities as an effort to increase knowledge about HIV AIDS prevention and transmission. This research takes the form of experimental research, namely by measuring the increase in respondents' knowledge through pretest and posttest after the intervention. The intervention takes the form of providing education related to knowledge of preventing HIV/AIDS transmission. The intervention that will be carried out to increase knowledge about safe sexual behavior and preventing HIV AIDS transmission will be carried out by providing education on preventing HIV AIDS transmission in key communities at the Mahameru Foundation for 40 respondents. Risky sexual behavior such as having sexual relations with irregular partners, not using condoms during sexual intercourse, having sexual relations under the influence of alcohol and drugs are still carried out by key communities. The level of knowledge regarding risky sexual behavior, how HIV AIDS is transmitted and how to prevent HIV AIDS before education is carried out is still low.

Synergistic Forcing of the Troposphere and Stratosphere on Explosively Developing Cyclones Over the North Pacific During Cold Season

AbstractThe mid‐latitude extreme weather disasters are often associated with explosively developing cyclones (ECs). Based on different vertical development characteristics, 4,608 ECs identified over the North Pacific in the cold season of 44 years of NCEP‐CFSR reanalyzes are divided into four types of upward development and four types of downward development categories. ECs with vertical upward (downward) development follow a northeastward (nearly eastward) path, mainly explosively developing over the Northwest Pacific (Asia continent and Pacific). Furthermore, utilizing the piecewise potential vorticity inversion method reveals the synergetic forcing of the turbulent heat transport and baroclinicity in the lower troposphere, the latent heat release in the middle levels, the upper‐level jet stream, and the downward intrusion of stratospheric potential vorticity on the ECs. Different configurations of these influences from the troposphere to the stratosphere result in the occurrences of eight types of ECs in the cold season over the North Pacific.

Assessing Radiology and Radiation Therapy Needs for Cancer Care in Low-and-Middle-Income Countries: Insight From a Global Survey of Departmental and Institutional Leaders

BackgroundThe global cancer burden and mortality rates are increasing, with significant disparities in access to care in low-and-middle-income countries (LMICs). This study aims to identify radiology and radiotherapy needs in LMICs from the perspective of departmental and institutional leaders. MethodsA survey was developed and conducted by the American Association of Physicists in Medicine (AAPM) Global Needs Assessment Committee (GNAC) and the AAPM International Council. The survey, organized into five sections (Introduction, Infrastructure Needs, Education Needs, Research Needs, and General Information), was open to respondents from March 1 to August 16, 2022. FindingsA total of 175 responses were received from six global regions: Africa (31.4%), Americas (17.7%), Eastern Mediterranean (14.3%), Europe (9.1%), South-East Asia (23.4%) and Western Pacific (4.0%). The greatest reported need was for new or updated equipment, particularly PET/CT imaging technology. There was also a high demand for clinical and equipment training. Approximately 25% of institutions reported a lack of radiology-based cancer screening programs due to high healthcare costs and a shortage of specialized equipment. Many institutions that expressed interest in research face funding and grant challenges. InterpretationThe findings highlight critical areas where organizations can support LMICs in enhancing radiology and radiotherapy services to mitigate the growing cancer burden.

Incidence of Non-Communicable Diseases in Urban and Rural Areas of Indonesia

Introduction: NCDs were known of causing 74% of deaths worldwide, and 77% of all these deaths are in low- and middle-income countries. The prevalence of NCD in Indonesia has increased over the past five years as it has in the majority of other Low Middle-Income Countries (LMICs) in the Asia Pacific area. The objective of this study is to examine the incidence of non-communicable diseases (NCDs) in urban and rural areas. Methodology: This study used secondary data from the Indonesian Family Life Survey conducted in 2014-2015 (wave 5). A total of 16,204 households and 50,148 individuals were interviewed by the IFLS-5 in 2014-2015. The data reflects the entire country of Indonesia and was collected by stratified random sampling from province to residence level. We involved respondents between the ages of 18 and 64 as the inclusion criterion for this research. The exclusion criteria include those with unknown or incomplete data. A total of 26,437 participants were involved in this study. Result: People with CKD were nearly the same in urban and rural areas (55.91% and 44.09%); cholesterol disease (76.16% and 23.84%); CVD (63.38% and 36.62%); hypertension (62.57% and 37.43%); diabetes (74.42% and 25.58%); stroke (67.65% and 32.35%). Conclusions: Chronic kidney disease was nearly equal in both urban and rural; while cholesterol, cardiovascular, hypertension, diabetes, and stroke were higher in urban areas. This could be worthwhile to consider as part of improving NCD prevention and treatment. Keywords: non-communicable, rural, urban.

Developing the professional identity of school counsellors in the Asia Pacific: Challenges and ways forward

AbstractBackgroundSchool counselling in the Asia Pacific region has experienced enormous development in the last few decades but faces many serious challenges as counsellors seek to respond to the needs of young people in a complex and fast‐changing environment.AimsThis article aimed to explore the challenges school counsellors face in finding a clear identity and sense of purpose.DiscussionWe outline the antecedents and consequences of a weak counsellor identity. We suggest that the future development of school counselling in the region rests on responding to the challenge of school counsellors finding a clear and robust identity by (1) adopting an ecological perspective and (2) developing culture‐specific, indigenous ways of counselling.ConclusionGiven that the development of school counselling in this region has a long way to go, we briefly sketch some research priorities for the years ahead, which may contribute to the realisation and articulation of a stronger professional identity for school counsellors.

Extreme dynamic connectedness and hedging strategy across commodity, bond, currency, and stock markets: Evidence from Asian Pacific, Canada, Mexico, and US countries

This study investigates the interconnections among green bonds, non-green bonds, the US Dollar Index, precious metals (gold and silver), the Dow Jones Commodity Index (DJCI), and stock markets in the Asia-Pacific region (including Australia, China, Japan, Malaysia, Philippines, Russia, Singapore, South Korea, and Thailand), Canada, Mexico, and the United States. Additionally, the research delves into the costs and effectiveness of hedging in a diversified stock portfolio. The findings unveil a substantial presence of significant spillovers across these markets. Green bonds, the US Dollar Index, DJCI, gold, silver, and the stock markets of Canada, Mexico, and the US are identified as net contributors to spillovers, while Asia-Pacific stock markets are recognized as net receivers of shocks. The spillover magnitude exhibited a moderate level pre-pandemic, experienced an upward trend during the COVID-19 and Russian-Ukraine conflict periods, and declined during the vaccine distribution phases. The impact of COVID-19 on spillover magnitude appears to be more pronounced than that during the Russia-Ukraine tension. Furthermore, the overall connectedness is observed to be dynamic over time, displaying sensitivity to crisis periods.

Meat consumption and incident type 2 diabetes: an individual-participant federated meta-analysis of 1·97 million adults with 100 000 incident cases from 31 cohorts in 20 countries

Meat consumption could increase the risk of type 2 diabetes. However, evidence is largely based on studies of European and North American populations, with heterogeneous analysis strategies and a greater focus on red meat than on poultry. We aimed to investigate the associations of unprocessed red meat, processed meat, and poultry consumption with type 2 diabetes using data from worldwide cohorts and harmonised analytical approaches. This individual-participant federated meta-analysis involved data from 31 cohorts participating in the InterConnect project. Cohorts were from the region of the Americas (n=12) and the Eastern Mediterranean (n=2), European (n=9), South-East Asia (n=1), and Western Pacific (n=7) regions. Access to individual-participant data was provided by each cohort; participants were eligible for inclusion if they were aged 18 years or older and had available data on dietary consumption and incident type 2 diabetes and were excluded if they had a diagnosis of any type of diabetes at baseline or missing data. Cohort-specific hazard ratios (HRs) and 95% CIs were estimated for each meat type, adjusted for potential confounders (including BMI), and pooled using a random-effects meta-analysis, with meta-regression to investigate potential sources of heterogeneity. Among 1 966 444 adults eligible for participation, 107 271 incident cases of type 2 diabetes were identified during a median follow-up of 10 (IQR 7-15) years. Median meat consumption across cohorts was 0-110 g/day for unprocessed red meat, 0-49 g/day for processed meat, and 0-72 g/day for poultry. Greater consumption of each of the three types of meat was associated with increased incidence of type 2 diabetes, with HRs of 1·10 (95% CI 1·06-1·15) per 100 g/day of unprocessed red meat (I2=61%), 1·15 (1·11-1·20) per 50 g/day of processed meat (I2=59%), and 1·08 (1·02-1·14) per 100 g/day of poultry (I2=68%). Positive associations between meat consumption and type 2 diabetes were observed in North America and in the European and Western Pacific regions; the CIs were wide in other regions. We found no evidence that the heterogeneity was explained by age, sex, or BMI. The findings for poultry consumption were weaker under alternative modelling assumptions. Replacing processed meat with unprocessed red meat or poultry was associated with a lower incidence of type 2 diabetes. The consumption of meat, particularly processed meat and unprocessed red meat, is a risk factor for developing type 2 diabetes across populations. These findings highlight the importance of reducing meat consumption for public health and should inform dietary guidelines.

Impact of May–June Antarctic Oscillation on July–August Heat-Drought Weather in Yangtze River Basin

Investigating the physical mechanism behind the formation of summer heat-drought weather (HDW) in the Yangtze River Basin (YRB) holds significant importance for predicting summer precipitation and temperature patterns in the region as well as disaster mitigation and prevention. This study focuses on spatiotemporal patterns of July–August (JA) HDW in the YRB from 1979 to 2022, which is linked partially to the preceding May–June (MJ) Antarctic Oscillation (AAO). Key findings are summarized as follows: (1) The MJ AAO displays a marked positive correlation with the JA HDW index (HDWI) in the southern part of upper YRB (UYRB), while showing a negative correlation in the area extending from the Han River to the western lower reaches of the YRB (LYRB); (2) The signal of MJ AAO persists into late JA through a specific pattern of Sea Surface Temperature anomalies in the Southern Ocean (SOSST). This, in turn, modulates the atmospheric circulation over East Asia; (3) The SST anomalies in the South Atlantic initiate Rossby waves that cross the equator, splitting into two branches. One branch propagates from the Somali-Tropical Indian Ocean, maintaining a negative-phased East Asia–Pacific (EAP) teleconnection pattern. This enhances the moisture flow from the Pacific towards the middle and lower reaches of the Yangtze River Basin (MYRB-LYRB). The other branch propagates northward, crossing the Somali region, and induces a positive geopotential height anomaly over Urals-West Asia. This reduces the southwesterlies towards the UYRB, thereby contributing to HDW variabilities in the region. (4) Partial Least Squares Regression (PLSR) demonstrated predictive capability for JA HDW in the YRB for 2022, based on Southern Ocean SST.

Expanded roles of community health workers to sustain malaria services in the Asia-Pacific: A landscaping survey.

Malaria Community Health Workers (CHWs) in the Greater Mekong Subregion (GMS) are an important component of malaria elimination efforts. As malaria declines with intensified efforts to eliminate by 2030, expanding their roles beyond malaria could help to sustain funding and provision of malaria services at the community level. Evidence of how programmes have implemented and managed CHWs performing both malaria and non-malaria roles across the Asia-Pacific region can provide insight into the viability of this strategy. A short survey was distributed to national malaria programmes and implementing organizations in the Asia-Pacific region in 2021-2022. The survey identified CHW programmes in the region, and collected information on malaria and non-malarial services provided by CHWs, characteristics of each identified programme, and the impact of COVID-19 on these programmes. 35 survey responses identified 28 programmes in 14 countries. The most frequently reported services provided by malaria CHWs were health promotion and education for malaria (13/14 countries) and other diseases (11/14); and COVID-19 related activities (10/14). Most programmes were financed wholly through donor funding (18/28 programmes), or donor plus government funding (6/28). Of 21 programmes which performed programme evaluation, only 2 evaluated their impacts on diseases beyond malaria. Declining donor funding, and COVID-19 related travel and activity restrictions were identified as implementation challenges. CHWs across the Asia Pacific provide a range of health services with malaria and are resilient under changing public health landscapes such as the COVID-19 pandemic. Further investigation into the impact of additional roles on malaria CHW performance and targeted health outcomes is needed to verify the benefits and feasibility of role expansion. As the GMS approaches elimination, and funding declines, verifying the cost effectiveness of malaria CHW programmes will be vital to persuade donors and countries to invest in malaria CHWs to sustain malaria services, and strengthen community-based health care.

Korean human resource management as number one: lessons for the Asia Pacific

ABSTRACT Despite the devastation caused by Japanese colonial rule and over three years of the Korean War, the Korean economy has created the Miracle on the Han River over the past half-century, joining the ranks of advanced nations. Although it started with low-wage and labour-intensive industries, the accumulation and utilization of human capital have prepared companies like Samsung Electronics, Hyundai Motor, Naver and Coupang for a new leap forward. However, global issues such as the climate crisis and sustainability, the dual labour market, adversarial labour relations and low birth rates with rapid ageing are new challenges for Korean-style HRM. This is a collection of articles dealing with the question of Korean HRM as a success factor of Korean development and a seed for problems destabilizing the Korean economic perspective in the 21st century.

Barriers, motivators and strategies to increase participation in genetic research among Asian and Black families of autistic individuals.

Genetic research can help advance our knowledge of autism and positively impact the progress of care for individuals with autism. Asian American and Pacific Islander (AAPI) and Black participants remain significantly underrepresented in genetic research in autism in the United States, including nationwide, multisite, genetic consortiums like Simons Foundation Powering Autism Research for Knowledge (SPARK). Few studies have explored the unique motivators and barriers that influence participation in genetics research across underrepresented groups with autism and strategies to increase participation. Therefore, the aim of this study was to understand the perspectives of AAPI and Black parents of individuals with autism about participating in genetic research, specifically motivators (e.g., desire to know more about the relationship between autism and genetics) and/or barriers (e.g., mistrust of research staff) that may impact their decision to participate in genetic research. Using a mixed-methods approach, we collected surveys (n = 134) across the United States and conducted three focus groups with parents of individuals with autism (n = 16) who identified as AAPI and Black from two large metropolitan cities. No significant differences were observed in the survey data but findings from the focus groups elucidate shared motivators for participation (e.g., to help advance the autism field for future generations) and nuanced differences in barriers that influence Black and AAPI parents' decision to participate (e.g., different beliefs about the source of autism). Practical suggestions to improve outreach and study engagement in genetic research in autism were identified and discussed.

Using mid-upper arm circumference z -score measurement to support youth malnutrition screening as part of a global sports and wellness program and improve access to nutrition care.

Historically, mid-upper arm circumference (MUAC) has been instrumental to identifying malnutrition in children under 5 years living in resource restricted settings. Less attention is directed to at-risk, school-aged youth. Updated and validated pediatric age- and gender-specific MUAC growth curves expand malnutrition screening opportunities (2 months-18 years) including overweight/obesity. An innovative partnership was created to integrate MUAC z-score measurement trainings and screenings in the Real Madrid Foundation's (RMF) Social Sports Schools (S3) program, which provide sports and wellness programming to under-resourced communities. This work aimed to investigate the feasibility of leveraging non-healthcare professionals (non-HCPs) to identify malnutrition risk as part of RMF S3. This global, two-part program on malnutrition risk identification included training adult facilitators and screening children attending RMF S3. RMF facilitators were trained with didactic lectures on malnutrition, and practical hands-on learning of proper MUAC z-score tape measurement. Aggregate data on facilitators and the number of times to correctly administer the MUAC z-tape were recorded. Aggregate data on child malnutrition risk screenings were collected. Nine countries participated representing Europe, Pacific Asia, Africa, Latin America, and North America. In total, 143 RMF facilitators were trained, and 318 children were screened across 11 sites. More than half of facilitators were male (56%, n = 80), and majority were coaches (41.3%, n = 59), followed by staff (25.2%, n = 36), and volunteers (16.1%, n = 23). Facilitator attempts ranged from 1 to 4 times for proper MUAC z-score administration with mean 2.12 (± 0.86). There were no significant differences for attempts among RMF facilitator types (p = 0.10). Sixteen percent (n = 51) of children screened were recommended for HCP referral, with concentrations in Pacific Asia (68%, n = 35), Latin America (24%, n = 12), and Africa (8%, n = 4). Findings from our sample demonstrate that integration of MUAC z-score based malnutrition risk screening within community sports and wellness programming among non-HCPs is feasible, and that some regions with less frequent access to routine health care may experience greater benefit from these programs. Equipping non-HCP facilitators in community sports and wellness programs with training on malnutrition screening provides a means to meet under-resourced families where they live to begin conversations around malnutrition risk with the hope of establishing additional pathways to care.

Enhancing energy efficiency in Asia-Pacific: Comprehensive energy policy analysis

The Asia-Pacific (APAC) region has undergone remarkable economic growth over the past three decades, significantly reducing poverty levels. However, the concurrent rise in energy consumption and its environmental impact necessitate the development of a sustainable energy system to sustain and accelerate this progress. Recognizing the critical role of energy efficiency, governments in the region have increasingly formulated and implemented energy policies, encompassing laws, regulations, and action plans. However, understanding the precise influence of these policies on energy efficiency remains a challenge. This study employs an endogenous stochastic frontier analysis (SFA) model using data from the Asia Pacific Energy Portal Policy database covering 23 emerging economies from 2000 to 2017 to assess how energy policies affect energy efficiency in the APAC region. The findings indicate that implementing energy policies correlates with an average increase in energy efficiency by 0.158%. However, the impact varies depending on whether the policies are laws, regulations, or strategies. Though the region's average energy efficiency standing is at 0.34, there has been a consistent upward trend observed from 2000 to 2017. Furthermore, optimizing aggregate energy policies has resulted in substantial energy savings, averaging 0.15 quadrillion Btu. In light of these results, we proposed some policy actions.

Risk of gastrointestinal bleeding in Asian patients receiving oral anticoagulants for stroke prevention in atrial fibrillation.

Non-vitamin K antagonist oral anticoagulants (NOACs) are increasingly used for stroke prevention in atrial fibrillation. At the Asia Pacific Advancing Patient care with EdoXaban 2023 meeting, experts shared insights on gastrointestinal bleeding with NOACs for stroke prevention in atrial fibrillation in Asian clinical practice, where NOACs have gained widespread acceptance due to their favourable profiles. Gastrointestinal bleeding risk varies amongst NOACs, emphasizing the importance of diligent patient assessment, dosage selection and vigilant monitoring. Edoxaban emerged as a viable option with a low gastrointestinal bleeding risk profile in Asian compared with non-Asian patients, supporting its continued clinical utilization for appropriate patients.

Interdecadal change in the relationship between the South China late rainy season rainfall and equatorial Pacific SSTs

Abstract The South China (SC) late rainy season rainfall (SCLR) is important to people’s livelihoods and properties of this densely populated and economically developed region. Based on observation and reanalysis datasets, this study identifies that the relationship between the SCLR and equatorial Pacific SSTs (EPSSTs) experiences an interdecadal change around the late 1970s. The SCLR is negatively correlated with the eastern EPSSTs during 1948–1977 (the previous epoch) but positively correlated with the central EPSSTs during 1978–2022, especially during the last three decades 1993–2022 (the post epoch). This is due to the interdecadal change in El Niño flavors and EPSSTs-tropical Atlantic SSTs (TASSTs) relationship. With the increasing frequency of central Pacific El Niños in the post epoch, the El Niño-related warm SST anomaly center shifts from the eastern equatorial Pacific (EEP) to the central equatorial Pacific (CEP). Correspondingly, the anomalous cyclone exerted by the CEP warming reaches SC and causes rainfall surplus there (westward propagation pathway). In contrast, the EEP warming in the previous epoch can’t influence the SCLR through the westward propagation pathway, but through shifting the westerly jet southward via heating the tropical troposphere. The southward shifted westerly jet crashes the Qinghai-Tibet Plateau, triggering cyclonic circulations across the northern East Asia and North Pacific, which in turn cause anticyclonic circulations over the western SC and reduce SC rainfall (eastward propagation pathway). On the other hand, the CEP warming in the post epoch barely influence the SCLR through the eastward propagation pathway because of the enhanced negative relationship between EPSSTs and TASSTs.
