HARMONIZE Asia: A Phase III Randomized Study to Investigate the Efficacy and Safety of Sodium Zirconium Cyclosilicate in Patients with Hyperkalemia in China.

PURPOSE: Sodium zirconium cyclosilicate (SZC) is an oral potassium (K+)-lowering therapy for adults with hyperkalemia. HARMONIZE Asia (ClinicalTrials.gov identifier: NCT03528681) evaluated the efficacy and safety of SZC in Chinese patients with hyperkalemia. METHODS: This Phase III, randomized, double-blind, placebo-controlled study recruited patients with serum K+ (sK+) ≥5.1 mmol/L at 35 sites in China. Patients received SZC 10 g three times daily (TID) for 24 or 48 hours during an open-label initial phase (OLP). Those patients achieving normokalemia (sK+ 3.5-5.0 mmol/L inclusive) entered a 28-day randomized (2:2:1) treatment phase (RTP) and received SZC 5 g, SZC 10 g, or placebo once daily. The primary endpoint was mean sK+ during RTP Days 8 to 29. Secondary endpoints included mean change in sK+ during the OLP, the proportion of patients who achieved normokalemia at the end of the OLP, the proportion that maintained normokalemia during the RTP, and time to recurrence of hyperkalemia. FINDINGS: In total, 270 patients received SZC 10 g TID during the OLP; 256 (94.8%) completed the OLP. During the OLP, mean sK+ decreased by 1.1 mmol/L from baseline (5.9 mmol/L; P < 0.001) and 87.4% of patients achieved normokalemia. During the RTP, SZC 5 g and 10 g reduced mean sK+ versus placebo in a dose-dependent manner (each P < 0.001); least-squares means (95% confidence interval [CI]) sK+ were 4.9 mmol/L (4.7, 5.0), 4.4 mmol/L (4.3, 4.6), and 5.2 mmol/L (5.1, 5.4) for SZC 5 g, 10 g, and placebo, respectively. At RTP end, the proportions of patients who maintained normokalemia were 58.8% (SZC 5 g; odds ratio vs placebo, 2.5 [95% CI: 1.1, 6.1; P = 0.035]), 76.5% (SZC 10 g; odds ratio vs placebo, 6.3 [95% CI: 2.6, 15.3; P < 0.001]), and 36.8% for placebo. Risk of recurrent hyperkalemia was reduced by 61.0% and 84.0% with SZC 5 g and SZC 10 g, respectively, versus placebo (each P < 0.001). During the RTP, the incidence of adverse events was numerically higher with SZC 5 g (50.0% of patients) and 10 g (44.0%) versus placebo (36.0%); driven primarily by peripheral edema and constipation. IMPLICATIONS: Both SZC doses demonstrated clinically relevant and statistically significant, dose-dependent efficacy in managing sK+ levels in Chinese patients with hyperkalemia, compared with placebo. SZC tolerability was broadly aligned with the known safety profile of SZC.

Confusing boundaries of the Labrador Tea species: dispersal history explains the lack of clear species structure.

BACKGROUND AND AIMS: The Labrador Teas (genus Rhododendron, subsection Ledum) are a complex of species widely distributed in the Northern Hemisphere. They occupy cold-resistant plant communities from highlands to forest understory and wetland habitats almost circumboreally and they are especially abundant in Northeast Asia (NE Asia) and northern North America (NN Am), still there are no clear species boundaries in this group. The genetic structure of species of the subsect. Ledum from Eurasia and North America as well as the dispersal history of the group require clarification. METHODS: Phylogeny and biogeography of the subsect. Ledum of the genus Rhododendron were assessed using phylogenetic trees constructed based on the analysis of variation in chloroplast petB-petD, trnV-ndhC, trnH-psbA, K2R-K707, atpB oligo2 - rbcL oligo5 and nuclear (ITS1) markers of four Eurasian and one American species (65 populations, 408 individuals). The data were evaluated with Maximum Parsimony and Bayesian analysis. Molecular dating and ancestral areas reconstruction were obtained. KEY RESULTS: Dense sampling revealed widespread presence of shared haplotypes and ribotypes among Ledum populations and species. Two American, three Eurasian and one mixed lineage diversified during the Neogene climate cooling and then rapidly dispersed during the Pleistocene. The ability to accumulate high genetic diversity and to preserve it across distribution ranges and generations prevented Ledum from lineage sorting. As a result, a species complex with a reserve of genetic variability appeared. CONCLUSIONS: Although no clear phylogenetic inference can be obtained at present, the plastid genealogy is consisted with the nuclear genealogy and demonstrates the processes involved in speciation in the Ledum species complex.

Post-Diagnosis HCV RNA Testing Rates Prior to HCV Treatment Among People Living With HIV With HCV Antibody Positivity in the Asia-Pacific Region.

HCV RNA test determines current active infection and is a requirement prior to initiating HCV treatment. We investigated trends and factors associated with post-diagnosis HCV RNA testing rates prior to HCV treatment, and risk factors for first positive HCV RNA among people living with HIV (PLHIV) with HCV in the Asia-Pacific region. PLHIV with positive HCV antibody and in follow-up after 2010 were included. Patients were considered HCV-antibody positive if they ever tested positive for HCV antibody (HCVAb). Repeated measures Poisson regression model was used to analyse factors associated with post-diagnosis HCV RNA testing rates from positive HCVAb test. Factors associated with time to first positive HCV RNA from positive HCVAb test were analysed using Cox regression model. There were 767 HCVAb positive participants included (87% from LMICs) of whom 11% had HCV RNA tests. With 163 HCV RNA tests post positive HCVAb test, the overall testing rate was 5.05 per 100 person-years. Factors associated with increased testing rates included later calendar years of follow-up, HIV viral load ≥1000 copies/mL and higher income countries. Later calendar years of follow-up, ALT >5 times its upper limit of normal, and higher income countries were associated with shorter time to first positive HCV RNA test. Testing patterns indicated that uptake was predominantly in high income countries possibly due to different strategies used to determine testing in LMICs. Expanding access to HCV RNA, such as through lower-cost point of care assays, will be required to achieve elimination of HCV as a public health issue.

The burden of cardiovascular disease in Asia from 2025 to 2050: a forecast analysis for East Asia, South Asia, South-East Asia, Central Asia, and high-income Asia Pacific regions.

Background: Given the rapidly growing burden of cardiovascular disease (CVD) in Asia, this study forecasts the CVD burden and associated risk factors in Asia from 2025 to 2050. Methods: Data from the Global Burden of Disease 2019 study was used to construct regression models predicting prevalence, mortality, and disability-adjusted life years (DALYs) attributed to CVD and risk factors in Asia in the coming decades. Findings: Between 2025 and 2050, crude cardiovascular mortality is expected to rise 91.2% despite a 23.0% decrease in the age-standardised cardiovascular mortality rate (ASMR). Ischaemic heart disease (115 deaths per 100,000 population) and stroke (63 deaths per 100,000 population) will remain leading drivers of ASMR in 2050. Central Asia will have the highest ASMR (676 deaths per 100,000 population), more than three-fold that of Asia overall (186 deaths per 100,000 population), while high-income Asia sub-regions will incur an ASMR of 22 deaths per 100,000 in 2050. High systolic blood pressure will contribute the highest ASMR throughout Asia (105 deaths per 100,000 population), except in Central Asia where high fasting plasma glucose will dominate (546 deaths per 100,000 population). Interpretation: This forecast forewarns an almost doubling in crude cardiovascular mortality by 2050 in Asia, with marked heterogeneity across sub-regions. Atherosclerotic diseases will continue to dominate, while high systolic blood pressure will be the leading risk factor.

Quality of Life and Burden of Moderate-to-Severe Atopic Dermatitis in Adult Patients Within the Asia-Pacific Region: A Cross-sectional Survey.

INTRODUCTION: The burden of atopic dermatitis (AD) is significant, with a substantial impact on quality of life (QoL). This cross-sectional study aimed to ascertain the burden of AD, its impact on QoL, and associated costs. METHODS: Patients with moderate-to-severe AD were enrolled from eight territories, namely Hong Kong, India, Japan, Mainland China, Singapore, South Korea, Taiwan, and Thailand. After screening was performed and informed consent was obtained, eligible participants were asked to provide responses on their AD symptoms, severity, treatment, and out-of-pocket costs via an online survey. QoL was assessed using EQ-5D-5L and Dermatology Life Quality Index (DLQI), while productivity loss was quantified using the Work Productivity and Activity Impairment (WPAI) questionnaire. Data from completed submissions were analyzed using descriptive statistics. The study was reviewed by the institutional review board in each territory. RESULTS: Median age of enrolled patients (N = 1103) was 41.0 years (interquartile range, IQR 16.0). The majority of patients reported that their head/neck, trunk, upper limbs, and lower limbs were affected during a flare. Topical (74.2%) and oral steroids (58.7%) were frequently prescribed to manage AD. Common atopic comorbidities were allergic urticaria (64.2%), allergic rhinitis (61.8%), and allergic conjunctivitis (51.5%). Median DLQI score was 13.0 (IQR 11.0), while median EQ-5D-5L (based on China value set) score was 0.8 (IQR 0.4); 87.2% and 77.2% of patients reported pain/discomfort and anxiety/depression on the EQ-5D-5L domains, respectively. Median total annual costs associated with AD were USD 10,128.52 (IQR 12,963.26) per patient, with indirect costs being the largest component. Findings from WPAI indicated that presenteeism is a major contributor to productivity loss. CONCLUSION: This multinational survey study showed that AD is associated with substantial QoL impairment and economic burden among Asian adult patients with moderate-to-severe AD. To alleviate burden of AD, clinicians should be more proactive in managing other concomitant conditions including psychological issues, and advocate for increased reimbursement for AD treatments.

A revision of Lycianthes (Solanaceae) in tropical Asia.

The genus Lycianthes (Dunal) Hassl. (Solanaceae) has in the past been treated as a section of the large genus Solanum L. but is more closely related to Capsicum L. Outside of the Americas, where the highest species diversity occurs, the genus is found in tropical and subtropical habitats from India to Japan and the Philippines, including the islands of Indonesia, New Guinea and the Solomons. The 19 species from Australia, New Guinea and the Pacific were treated in 'PhytoKeys 209'. Here I treat the remaining 10 species occurring across Asia; including two native species, L.biflora (Lour.) Bitter and L.oliveriana (Lauterb. & K.Schum) Bitter, and one cultivated species, L.rantonnetii (Carrière) Bitter that were also included in the earlier work. The Asian species treated here occupy a wide range of forested and disturbed habitats and are diverse in habit, ranging from epiphytic vines to small or medium sized trees, shrubs or creeping herbs. Many of the species are weedy plants of highly disturbed habitats and are best characterised as "ochlospecies", with complex polymorphic variation. Lycianthesrantonnetii, a species native to southern South America, is recorded as cultivated in India and Pakistan, but may be more widespread than collections indicate. The history of taxonomic treatments of Lycianthes in Asia is discussed, along with details of morphology found in all species. All species are treated in full, with complete morphological descriptions, including synonymy, lecto- or neotypifications, discussions of ecology and vernacular names, distribution maps and preliminary conservation assessments (for all except the cultivated L.rantonnetii). Searchable lists of all specimens examined are presented as Suppl. materials 1, 2.

Contributions on a small collection of the former Subulinidae Fischer & Crosse, 1877 (Eupulmonata, Achatinoidea) with catalogue of the Glessula and Rishetia species recorded from Myanmar.

The taxonomy of subulinid snails in Myanmar has been evaluated, resulting in the recognition of 40 species and subspecies across nine genera: Allopeas, Bacillum, Curvella, Glessula, Opeas, Paropeas, Rishetia, Tortaxis, and Zootecus. Nine species are re-described based on recently collected specimens, and two new species, Glessulamandalayensis Man & Panha, sp. nov. from Mandalay Region and Tortaxiscylindropsis Man & Panha, sp. nov. from Shan State are introduced. The genitalia and radula of Zootecuspullus was studied for the first time. This study also presents a comprehensive list of all subulinid species recorded to date from Myanmar. The type specimens and authenticated museum specimens have been illustrated with accompanying taxonomic remarks and nine species formerly assigned in Glessula are now placed in Rishetia: R.akouktoungensis, R.baculina, R.basseinensis, R.burrailensismaxwelli, R.kentungensis, R.limborgi, R.nathiana, R.pertenuis, and R.pertenuismajor.

Individual and community-level determinants of quality antenatal care in six South Asian countries.

Maternal health is a global public health concern. The paucity of antenatal care (ANC) during pregnancy is directly associated with maternal mortality. This study assessed the individual and community-level determinants of quality  ANC in six South-Asian countries. Data were obtained from a Demographic health survey of six South-Asian countries. This study included a sample of 180,567 (weighted) women aged 15-49 who had given birth in the preceding three years prior to the survey. The quality of ANC was determined by assessing whether a woman had received blood pressure monitoring, urine and blood sample screening, and iron supplements at any ANC visits. Frequency, percentage distribution, and inferential analysis (multilevel mixed-effects model) were conducted. The proportion of quality antenatal care utilization in South Asia was 66.9%. The multilevel analysis showed that women aged 35-49 years (AOR = 1.16; 95% CI = 1.09-1.24), higher education (AOR = 2.84; 95% CI = 2.69-2.99), middle wealth status (AOR = 1.55; 95% CI = 1.49-1.62), richest wealth status (AOR = 3.21; 95% CI = 3.04-3.39), unwanted pregnancy (AOR = 0.92; 95% CI = 0.89-0.95) and 2-4 birth order (AOR = 0.86; 95% CI = 0.83-0.89) were among the individual-level factors that were significantly associated with quality ANC utilization. In addition, rural residence (AOR = 0.77; 95% CI = 0.74-0.8), and big problem - distance to health facility (AOR = 0.63; 95% CI: 0.53-0.76) were the among community level factors there were also significantly associated with use of quality ANC. Meanwhile, women who lived in India (AOR: 22.57; 95% CI: 20.32-25.08) and Maldives (AOR: 33.33; 95% CI: 31.06-35.76) had higher odds of quality ANC than those lived in Afghanistan. Educational status, wealth status, pregnancy wantedness, sex of household head, birth order, place of residence, and distance to health facility were associated with quality ANC. Improving educational status, improving wealth status, reducing the distance to health facilities, and providing rural area-friendly interventions are important to increase the quality of ANC in South Asia.

Climate change from the Asia-Pacific perspective: What an allergist needs to know and do.

Allergic diseases such as asthma, atopic dermatitis, and food allergies are a burgeoning health challenge in the Asia-Pacific region. Compounding this, the region has become increasingly susceptible to the impacts of climate change. The region has weathered extreme precipitation, intense heat waves, and dust storms over the recent decades. While the effects of environmental and genetic factors on allergic diseases are well understood, prevailing gaps in understanding the complex interactions between climate change and these factors remain. We aim to provide insights into the various pathways by which climate change influences allergic diseases in the Asia-Pacific population. We outline practical steps that allergists can take to reduce the carbon footprint of their practice on both a systemic and patient-specific level. We recommend that allergists optimize disease control to reduce the resources required for each patient's care, which contributes to reducing greenhouse gas emissions. We encourage the responsible prescription of metered dose inhalers by promoting the switch to dry powder inhalers for certain patients, at each clinician's discretion. We also recommend the utilization of virtual consultations to reduce patient travel while ensuring that evidence-based guidelines for rational allergy management are closely adhered to. Finally, eliminating unnecessary testing and medications will also reduce greenhouse gas emissions in many areas of medical care.

Factors affecting behavioral intentions of farmers in Southeast Asia to technology adoption: A systematic review analysis.

Agriculture remains one of the most vital economic sectors in Southeast Asia. However, the progress of this sector has been hindered by small-scale production, limited technology application, decreasing agricultural land size and quality, climate change, rapid urbanization, low productivity, and aging farmers. Technology adoption by rural farmers is still lacking, and the factors affecting farmers' behavioral intentions are still unclear, especially in Southeast Asia. Therefore, this study aims to determine the factors affecting behavioral intentions toward technology adoption among rural Southeast Asian farmers. A systematic literature review was performed to determine the factors affecting behavioral attention to technology adoption among smallholder farmers in Southeast Asia. Approximately 18 related studies were found based on the systematic review. According to the results of the study, farmers' behavioral intentions toward technology adoption can be classified as internal factors or external factors. Internal factors explain behavior, while external factors explain household, institutional, technological, social, and economic factors. The review revealed 21 factors categorized into five subthemes: household-specific factors, institutional factors, economic factors, technology factors, and behavior factors. This study is important because agriculture remains one of the most vital and pillar economic sectors in Southeast Asia. In addition, it has become a guideline for determining farmers' behavioral intentions toward the adoption of new agricultural technology.

Setting the Priorities for LGBT+ Research and Intervention Effort in Malaysia Through Community Voices: A Brief Report.

Internationally, there is a growing acceptance of gender and sexuality diversity and acknowledgment of LGBT + identities as health determinants. However, caution is warranted when applying research and intervention priorities from Global North countries to regions where LGBT + identities remain criminalized. In 2024, Malaysia maintains legal stances persecuting LGBT + individuals and shows no intent to address this human rights issue. This study offers an overview of pivotal issues identified by LGBT + communities in Malaysia that urgently require attention and resolution. Data were employed from a large-scale community-based survey: the KAMI Survey that recruited LGBT + participants in Malaysia in late 2023 and descriptive analyses were conducted on the responses of 637 participants (mean age = 27.75). Results revealed key issues deemed 'very important' to address by participants comprised HIV/AIDS, training for healthcare providers, police mistreatment, and discrimination, with more than 80% reporting each of these. When prompted to select a single issue for urgent resolution, three-fifths (61.0%) prioritized 'criminalizing laws affecting LGBT + individuals'. Echoing prolonged advocacy by local LGBT + community organizations, the author emphasizes the need for collective allyship across stakeholders to develop evidence-based practices and policies to address the concerns articulated in this paper.

Health Insurance Schemes and Their Influences on Healthcare Variation in Asian Countries: A Realist Review and Theory's Testing in Thailand.

BACKGROUND: Various features in health insurance schemes may lead to variation in healthcare. Unwarranted variations raise concerns about suboptimal quality of care, differing treatments for similar needs, or unnecessary financial burdens on patients and health systems. This realist review aims to explore insurance features that may contribute to healthcare variation in Asian countries; and to understand influencing mechanisms and contexts. METHODS: We undertook a realist review. First, we developed an initial theory. Second, we conducted a systematic review of peer-reviewed literature in Scopus, MEDLINE, EMBASE, and Web of Science to produce a middle range theory for Asian countries. The Mixed Methods Appraisal Tool (MMAT) was used to appraise the methodological quality of included studies. Finally, we tested the theory in Thailand by interviewing nine experts, and further refined the theory. RESULTS: Our systematic search identified 14 empirical studies. We produced a middle range theory in a context-mechanism-outcome configuration (CMOc) which presented seven insurance features: benefit package, cost-sharing policies, beneficiaries, contracted providers, provider payment methods, budget size, and administration and management, that influenced variation through 20 interlinked demand- and supply-side mechanisms. The refined theory for Thailand added eight mechanisms and discarded six mechanisms irrelevant to the local context. CONCLUSION: Our middle range and refined theories provide information about health insurance features associated with healthcare variation. We encourage policy-makers and researchers to test the CMOc in their specific contexts. Appropriately validated, it can help design interventions in health insurance schemes to prevent or mitigate the detrimental effects of unwarranted healthcare variation.

Correlates of Tobacco Use Among People with Mental Illness Within Asia: A Scoping Review.

Tobacco use among people with mental illness is one of the contributing risk factors for premature morbidity and mortality. Two in three people with mental illness are current smokers with deteriorating physical health and quality of life. This review outlines the prevalence and predictors of tobacco use among people with mental illness in Asia. Twenty-five cross-sectional studies were selected from the exhaustive search of databases. Ten countries emerged based on the number of studies conducted within Asia among people diagnosed with mental illness and tobacco use, namely, India (8), China (7), Pakistan (2), Singapore (2), Sri Lanka (01), Japan (01), Jordan (01), Malaysia (01), Korea (01), and Taiwan (01). The prevalence of tobacco use was in the range of 3.6% to 89.4%, with the measure of precision at 95% confidence. The highest and lowest prevalence was reported in China, followed by India. Being male, separated, lower education, unemployed, lack of family support, a psychotic diagnosis, lack of knowledge, motivation, and a coping mechanism were predictors of tobacco use. This review emphasized the extent and predictors of tobacco use among this vulnerable group that need to be reflected while initiating and implementing cessation strategies by healthcare providers.

Cultural roots of the myopia boom in Confucian Asia and their implications.

Current evidence implicates educational pressures and reduced outdoor time as major causes of myopia. This paper examines the ongoing battle against the myopia epidemic in East Asia, including its cultural offshoots such as Singapore, where over 80% of young adults are myopic. East Asian societies share deeply rooted Confucian values that attach great importance to education and familial obligations, with heavy parental investment in education and the perception that academic excellence reflects filial piety. Coupled with a strong emphasis on standardised test results, East Asian children face intense educational pressures from a young age. Existing education-based myopia prevention strategies focus either on top-down school reforms to promote more outdoor time for students during school hours or on bottom-up awareness initiatives encouraging lifestyle changes. However, the entrenched Confucian worldview suggests that more extensive top-down reforms aimed at reducing competition in education, combined with widespread bottom-up awareness initiatives targeting the public-particularly parents, given their active involvement in children's education outside of school-may be required to truly turn the tide on myopia.

Correlates of lifestyle patterns among children in Singapore aged 10 years: the growing up in Singapore towards healthy outcomes (GUSTO) study.

OBJECTIVE: To characterise lifestyle patterns (comprising dietary and movement behaviour aspects) of children in Singapore and examine the correlates of these patterns. DESIGN: An observational study approach was used. Children recorded their diet and activities over two weekdays and two weekend days on a validated web-based assessment, My E-Diary for Activities and Lifestyle (MEDAL). Lifestyle patterns were derived using principal component analysis, and the correlations of these with multiple known determinants organised by distal, intermediate, and proximal levels of influence were studied. SETTING: Children of the Growing Up in Singapore Towards healthy Outcomes (GUSTO) cohort. PARTICIPANTS: Ten-year-old children (n = 397). RESULTS: Three lifestyle patterns, "high snacks and processed food", "balanced" and "mixed", were identified. We focused on the more health-promoting "balanced" pattern, characterised by lower screen-viewing and higher consumption of fruits, vegetables, wholegrains, and dairy. Among the distal factors, girls were more adherent to the "balanced" pattern compared to boys, and children of parents with lower education levels were less adherent to this pattern. Among intermediate factors, children of mothers with higher diet quality were more adherent to the "balanced" pattern. Among the proximal factors, engagement in active transport, leisure sports, and educational activities outside of school were positively associated with the "balanced" pattern, whereas screen-viewing while travelling was negatively associated with this pattern. Having siblings, pet ownership, mother's physical activity, parenting style, parental bonding, child's outdoor time, and breakfast consumption were not associated with children's lifestyle patterns. CONCLUSIONS: These findings provide direction for future interventions by identifying vulnerable groups and contexts that should be prioritised.

Clinical Practice Guidelines for the Management of Type 2 Diabetes in South Asia: A Systematic Review.

BACKGROUND: Clinical practice guidelines (CPGs) are a helpful tool for the evidence-based management of Type 2 Diabetes Mellitus (T2D). The aim of this systematic review was to synthesize and appraise the scope and quality of South Asian T2D CPGs. METHODS: This PROPSERO registered (CRD42023425150) systematic review adhered to the 2020 PRISMA guidelines. We searched the PubMed, Embase, Cochrane, and Google Scholar databases for relevant guidelines. Data synthesis was performed using a qualitative approach and methodological quality was assessed using the Appraisal of Guidelines for Research and Evaluation (AGREE) II tool. RESULTS: We identified eleven unique CPGs (three each from Pakistan and Sri Lanka, two from India, and one each from Bangladesh, Nepal, and Bhutan) which were published or updated between 2017 and 2023. The CPGs included recommendations regarding screening, diagnosis, prevention, and management of T2D and its acute and chronic complications, comorbidities, and fasting with T2D. The AGREE II mean domain scores ranged from 37 % to 80 %; three CPGs were 'recommended for clinical use,' seven were 'recommended for use with modifications' and one was deemed unfit for implementation. CONCLUSION: The present review summarized and appraised broadly CPGs from South Asia for T2D and can help direct improvements to future iterations.

A systematic review and meta-analysis of chronic obstructive pulmonary disease in asia: risk factors for readmission and readmission rate.

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) often require hospital readmission because of exacerbation of their condition. These frequent exacerbations reduce quality of life, work performance, and emotional health. However, few studies have investigated the risk factors for readmission and readmission rates in Asian patients with COPD. We conducted a systematic review to identify and understand the major risk factors for readmission in patients with COPD in Asia and the readmission rate. METHOD: We searched PubMed, MEDLINE, Embase, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, and China Biomedical Literature Database from database inception to September 2023 to identify studies on the readmission rate and risk factors for COPD in Asian patients. Chinese search terms included "COPD," "chronic obstructive pulmonary disease," "risk factors," "recurrence," "readmission," and "acute exacerbation." English search terms included "chronic obstructive pulmonary disease," "COPD," "lung emphysema," "hospital admission," "patient readmission," and "readmission." We extracted first author, publication year, research area, sample size, sex, risk factors, and readmission rates. The included studies' quality was evaluated using the Agency of Healthcare Research and Quality. Meta-synthesis was conducted on readmission rates and risk factors for readmission. Subgroups were formed by age, research area, sample size, and research type, and meta-regression analysis was conducted on the 30-day, 90-day, and 365-day readmission rates of patients to determine the source of heterogeneity. Finally, the results' robustness was evaluated using sensitivity analysis. Begg and Egger tests were used to evaluate publication bias. RESULTS: Meta-analysis of 44 studies, with 169,255 participants, indicated that risk factors for COPD readmission in Asia included: history of multiple hospital admissions, ≥ 3 comorbidities, male sex, ratio of eosinophils percentage ≥ 2%, body mass index < 18.5, smoking history, pulmonary heart disease comorbidity, COPD assessment test score > 20, nutritional disorder, Neutrophil-to-Lymphocyte ratio > 7, and FEV1 < 50. The 30-, 90-, and 365-day readmission rates of patients were 19%, 31%, and 42%, respectively. CONCLUSIONS: Patients with COPD in Asia generally have high readmission rates and different risk factors. To reduce healthcare, economic, and social burdens, interventions should address major risk factors, early prevention, and screening.

A Systematic Review and Meta-Analysis of Aeromonas-Associated Diarrhea Among Children in Asia.

Background: Diarrheal illness is a prominent public health worry in developing countries, resulting in high mortality among children. Sociodemographic characteristics and geographic settings are the main effective factors for the increased incidence of childhood diarrhea. Aeromonas is a neglected organism capable of causing dysentery and diarrhea. The aim of this systematic review and meta-analysis was to determine the prevalence of Aeromonas as an agent in the causation of diarrhea in Asian children. Methods: We conducted a systematic review using Web of Science, PubMed, Wiley Online Library, Science Direct, and Google Scholar for peer-reviewed articles published between January 2000 and February 2023. We considered studies that found Aeromonas in diarrheal stool. A random-effects model was used to determine the pooled prevalence of Aeromonas. Results: Our search returned 2,057 articles, with 17 articles from seven Asian nations being included in the systematic review. The pooled prevalence of Aeromonas was 4.5% (95% confidence interval [CI]: 2.9%-6.8%), with heterogeneity (I2 = 96.85; p < 0.001). There was a greater prevalence in areas with high population living in poverty (12.2%; 95% CI: 5.8%-24%) and lower-middle-income countries (5.0%; 95% CI: 2.7%-9.0%). In addition, the prevalence of Aeromonas was greater in South Asia (10.0%; 95% CI: 5.6%-17.2%), in India (12.9%; 95% CI: 6.8%-23%), and in countries with open defecation rate of 5%-25% (11.3%; 95% CI: 6.3%-19.2%). Conclusion: The prevalence of Aeromonas-associated diarrhea in children in Asia estimated in the present study highlighted the high burden of Aeromonas in some parts of Asia.

One-year outcomes of rate versus rhythm control of atrial fibrillation in the Kerala-AF Registry.

Background: There is ongoing debate around rate versus rhythm control strategies for managing atrial fibrillation (AF), however, much of the data comes from Western cohorts. Kerala-AF represents the largest prospective AF cohort study from the Indian subcontinent. Objectives: To compare 12-month outcomes between rate and rhythm control strategies. Methods: Patients aged ≥18 years with non-transient AF were recruited from 53 hospitals across Kerala. Patients were stratified by rate or rhythm control. The primary outcome was a composite of all-cause mortality, arterial thromboembolism, acute coronary syndrome or hospitalization due to heart failure or arrhythmia at 12 months. Secondary outcomes included bleeding events and individual components of the primary. Predictors of the composite outcome were analysed by logistic regression. Results: A total of 2901 patients (mean age 64.6 years, 51% female) were included (2464 rate control, 437 rhythm control). Rates of the primary composite outcome did not differ between groups (29.7% vs 30.0%; p = .955), nor did any component of the primary. Bleeding outcomes were also similar (1.6% vs 1.9%; p = .848). Independent predictors of the primary composite outcome were older age (aOR 1.01; p = .013), BMI <18 (aOR 1.51; p = .025), permanent AF (aOR 0.78; p = .010), HFpEF (aOR 1.40; p = .023), HFrEF (aOR 1.39; p = .004), chronic kidney disease (aOR 1.36; p < .001), and prior thromboembolism (aOR 1.31; p = .014). Conclusion: In the Kerala-AF registry, 12-month outcomes did not differ between rate and rhythm control cohorts.
