A systemic analysis of Creutzfeldt Jakob disease cases in Asia

Creutzfeldt Jakob Disease (CJD) is a rapidly progressive, fatal neurodegenerative disorder, also known as a subacute spongiform encephalopathy. There are three major subtypes of CJD i.e. Sporadic CJD, which occurs for reasons unbeknown to science (85% of known cases), Genetic or Familial CJD which is characterized by the presence of mutations in the human prion protein (PRNP) gene (10-15% cases) and Iatrogenic CJD that occurs via accidental transmission through medical and surgical procedures (1-2% cases). CJD cases occur globally with 1 case per one million population/year. Considerable data is available related to the incidence and prevalence of CJD in Europe and America. However, the global surveillance database is yet to include Asia even though several Asian countries have their own CJD monitoring units. sCJD is the highest among all CJD cases in Asia. China (1957) and Japan (1705) have reported more cases of sCJD than any Asian country and Hong Kong (1) has reported the least. On the other hand, gCJD is highest in Japan (370) and least in India (2). Our analysis establishes the presence of all variants of CJD across Asia. However, in most Asian countries in general and Southeast Asian countries in particular, CJD cases are misdiagnosed and often underreported. Since Asia is the most populated continent in the world, the actual global prevalence of CJD cannot be estimated until and unless these countries are accounted for. Concrete and reliable surveillance networks are needed across Asia to evaluate the prevalence and incidence of CJD in the region. [Figure: see text]The graphical abstract demonstrates the prevalence of CJD cases in the world and systematically analyses the incidence of CJD in Asian countries between the year 1986-2022. Highest number of cases were reported in Japan followed by China. The study emphasizes the need for assimilation of Asian data in global prevalence.

Expert recommendations for the management of iron deficiency in patients with heart failure in Asia

BACKGROUND

Iron deficiency is a common comorbidity in heart failure (HF) and is independently associated with a worse quality-of-life and exercise capacity, as well as increased risk of hospitalization, regardless of anemia status. Although international guidelines have provided recommendations for the management of iron deficiency in patients with HF, guidelines in Asia are less established, and practical use of guidelines for management of iron deficiency is limited in the region.

METHODS

A panel comprising cardiologists from China, Hong Kong, India, Japan, Malaysia, Pakistan, Philippines, Singapore, South Korea, Taiwan, and Thailand convened to share insights and provide guidance for the optimal management of iron deficiency in patients with HF, tailored for the Asian community.

RESULTS

Expert opinions were provided for the screening, diagnosis, treatment and monitoring of iron deficiency in patients with HF. It was recommended that all patients with HF with reduced ejection fraction should be screened for iron deficiency, and iron-deficient patients should be treated with intravenous iron. Monitoring of iron levels in patients with HF should be carried out once or twice yearly. Barriers to the management of iron deficiency in patients with HF in the region include low awareness of iron deficiency amongst general physicians, lack of reimbursement for screening and treatment, and lack of proper facilities for administration of intravenous iron.

CONCLUSIONS

These recommendations provide a structured approach to the management of iron deficiency in patients with HF in Asia.

Patients' perceptions of patient-centered communication with healthcare providers and associated factors in Japan - The INFORM Study 2020

OBJECTIVE

To describe patients' perceptions of the patient-centeredness of their communication with healthcare providers in Japan, and to examine factors associated with these perceptions.

METHODS

We analyzed the cross-sectional data from the INFORM Study 2020, which is a nationwide survey on health information access in Japan. A total of 3605 respondents completed the survey. Our primary outcome was the nine elements of the patient-centered communication scale (PCCS), which was compiled from 2703 respondents (75.0%) reporting at least one provider visit within 12 months. It was rated on a four-point Likert scale: always, usually, sometimes, and never. We used binary logistic regression to examine the association between sociodemographic and health-related variables, and each element of the PCCS.

RESULTS

For all elements, the percentage of respondents who agreed that their healthcare providers always communicated in a patient-centered way was low (17-31%). Patients with higher age, higher education, poorer general health status and a larger number of visits to providers in the previous 12 months were more likely to have positive perception.

CONCLUSION

Patient-centered communication as reported in a national sample in Japan was low.

CLINICAL IMPLICATIONS

Efforts are needed to improve the patient-centeredness of patient-provider communication in Japan to optimize health outcomes.

Injecting drug use increases the risk of death in HIV patients on antiretroviral therapy in Vietnam

The Human Immunodeficiency Virus (HIV) epidemic remains a major public health issue worldwide. In Vietnam, the HIV epidemic is essentially driven by people who inject drugs (PWID). This study aims to compare mortality and loss to follow-up (LTFU) between PWID and other patients. From June 2017 to April 2018, HIV-infected adults were enrolled in a prospective cohort from time of ART initiation in six provinces of North Vietnam. The end date was July 2020. Mortality and LTFU were described using competing-risk survival models. Factors associated with mortality and with LTFU were identified using Cox models with a competing-risk approach. Of the 578 participants, 261 (45.2%) were PWID and almost exclusively male. 49 patients died, corresponding to a mortality rate (95% confidence interval (CI)) of 3.7 (2.8-4.9) per 100 person-months, and 79 were lost to follow-up, corresponding to a rate (95% CI) of 6.0 (4.8-7.4) per 100 person-months. PWID were at higher risk of death but not of LTFU. Overall, LTFU was high in both groups. Latecomers to clinical visits were more at risk of both death and LTFU. Therefore, this should be a warning to clinical teams and preventive actions taken in these patients.Trial registration: ClinicalTrials.gov identifier: NCT03249493..

Adjuvant treatment for locally advanced gastric cancer: an Asian perspective

Standard adjuvant treatment for locally advanced gastric cancer (LAGC) is regionally different. Whereas perioperative chemotherapy is the standard in Western populations, D2 gastrectomy followed by adjuvant chemotherapy has been the standard in East Asia. Recently, the pivotal phase 3 PRODIGY and RESOLVE studies have demonstrated survival benefits of adding neoadjuvant chemotherapy to surgery followed by adjuvant chemotherapy over up-front surgery followed by adjuvant chemotherapy in Asian patients. Based on these results, neoadjuvant chemotherapy is considered one of the viable options for patients with LAGC. In this review, various aspects of neoadjuvant chemotherapy will be discussed for its optimal application in Asia. Candidates for neoadjuvant chemotherapy should be carefully chosen in consideration of the inaccurate aspects of radiological clinical staging and its potential benefit over up-front surgery followed by a decision on adjuvant chemotherapy according to the pathological stage. Efforts should continuously be made to optimally apply neoadjuvant chemotherapy to patients with LAGC, considering various factors, including a more accurate radiological assessment of the tumor burden and the optimization of post-operative chemotherapy. Future neoadjuvant trials involving novel agents for Asian patients should be designed based on proven Asian regimens rather than adopting Western regimens.

The incidence of Clostridium difficile infection in children with and without inflammatory bowel diseases: A single-center study in Taiwan from 2006 to 2019

BACKGROUND

The incidence of Clostridium difficile infection (CDI) is increasing around the world, and patients with inflammatory bowel disease (IBD) have a higher risk of obtaining CDI. The data on the incidence rate of CDI in the Asian pediatric IBD population was lacking.

METHODS

We retrospectively collected data from a tertiary medical center in Taipei, Taiwan. All patients aged 1-18 years old who visited the outpatient department or were admitted to our hospital between 2006 and 2019 were included. CDI was defined as positive stool C. difficile toxin or C. difficile culture results with appropriate antibiotic use within the range of 7 days prior or 14 days after the result.

RESULTS

We compared the average annual incidence of CDI before and after 2013. The average incidence of community-acquired CDI (CA-CDI) increased from 0.063 to 0.564 cases per 1,000 visits, with a rate ratio (RR) of 8.82 (95% CI 5.74-14.38). In patients with IBD, the rate increased from 26.738 to 278.873 cases per 1,000 visits (RR=10.12, 95% CI: 4.57-29.02). The average incidence rate increased from 0.685 to 1.874 cases per 1,000 admissions in pediatric general patients (RR = 2.72, 95% CI 1.82-4.20) and from 14.706 to 62.500 cases per 1,000 admissions in pediatric IBD patients (RR = 3.77, 95% CI 0.71-93.53).

CONCLUSIONS

Both CA-CDI and healthcare facility-onset CDI (HO-CDI) were increasing substantially in the pediatric population over the past decade in Taiwan. Compared to the general pediatric population, pediatric IBD patients had a much higher incidence of CDI.

Review on epidemiology, disease burden, and treatment patterns of IgA nephropathy in select APAC countries

BACKGROUND

Immunoglobulin type A (IgA) nephropathy is the most common primary glomerulonephritis (GN) worldwide with higher rates in East and Pacific Asia compared to North America and Europe. Despite high reported prevalence of IgAN in these countries, the overall disease prevalence across Asia is not available. Treatment patterns of IgAN patients across Asian countries have also not been summarized. The aim of this study was to review and summarize evidence on IgA nephropathy prevalence, treatment patterns, and humanistic and economic burden in mainland China, Taiwan, South Korea, Japan, and Australia.

METHODS

A targeted literature review was conducted in PubMed and local databases in China (including Taiwan), South Korea, Japan, and Australia between January 2010-December 2021. Website literature searches were conducted using Google Scholar and Baidu.

RESULTS

Sixty-nine publications and 3 clinical guidelines were included. Incidence ranged from 0 to 10.7 per 100 000 people per year in Australia, Japan, and Taiwan, and ranged from 6.3 to 24.70% among patients who underwent renal biopsy in mainland China. Prevalence and diagnosis rates ranged from 0 to 72.1% in mainland China, South Korea, Taiwan, Japan, and Australia. Mortality rates in mainland China, South Korea, and Japan varied widely. The top 3 commonly used therapies were angiotensin-converting enzyme inhibitor/angiotensin receptor blockers (0.9-99.6%), corticosteroids (3.5-100%), and immunosuppressants (1.6-85.5%) in Japan, mainland China, and South Korea. Patient quality of life was measured by different tools, and annual hospitalization costs ranged from $1 284.73 to $2 252.12 (2015-2018) in China.

CONCLUSIONS

The prevalence of IgA nephropathy among the general population in select countries/regions is not commonly available, despite evidence from studies and clinical guidelines. In addition, it is observed across geographic regions that heterogeneity exists in prevalence rates, and large variations exist in treatment patterns. There is need to fill in these gaps to understand the contributing factors behind the differences through population-based, multi-center, and real-world studies.

Association of diet quality with hand grip strength weakness and asymmetry in a multi-ethnic Asian cohort

Hand grip strength (HGS) is an important diagnostic tool for sarcopenia and a reliable predictor for age-related chronic diseases and mortality. Interventions in nutrition have been shown as a low-cost strategy to maintain muscular strength and mass. However, there are limited data on the effect of diet on HGS in Southeast Asian populations. This study aims to investigate the association of diet quality with HGS weakness and asymmetry in a multi-ethnic population in Singapore. This cross-sectional study used data from the Singapore Multi-Ethnic Cohort (n = 1547). Dietary data were collected using a validated semi-quantitative FFQ and summarised as the Dietary Quality Index - International (DQI-I). HGS was calculated as the maximum value of six measurements from both hands. HGS weakness and asymmetry were defined using well-recognised criteria. Multivariable linear regression and logistic regression were utilised for continuous and binary outcomes, respectively, adjusting for age, sex, ethnicity, physical activity and smoking status. It was found that the highest quartile of DQI-I was significantly associated with higher HGS (β = 1·11; 95 % CI 0·41, 1·82; Pfor trend < 0·001) and lower odds of HGS asymmetry (OR = 0·71; 95 % CI 0·53, 0·94; Pfor trend = 0·035) and both HGS weakness and asymmetry (OR = 0·50; 95 % CI 0·32, 0·76; Pfor trend = 0·004). Among the different components of DQI-I, only dietary adequacy was significantly associated with higher HGS (Pfor trend < 0·001) and lower odds for both HGS weakness and asymmetry (Pfor trend = 0·006). Our findings support that DQI-I, an indicator of overall diet quality, can be used to provide dietary guidelines for prevention and management of muscle wasting, sarcopenia and frailty.

A qualitative study of career decision making among African and Asian international medical students in China: process, challenges, and strategies

China hosts around 68,000 international medical students (IMSs) primarily from lower income countries in Africa and Asia, who have the potential to contribute to international medical services. Understanding how these IMSs make career decisions can help better address the issue of global medical workforce shortage. However, such research is limited. Our study aims to explore the career decision-making process of China-educated IMSs, the challenges they experienced and the strategies they employed.In this exploratory qualitative study, we conducted semi-structured interviews with IMSs educated in China in 2022 using purposeful sampling. Twenty virtual one-on-one interviews were conducted, and data were analysed through directed qualitative content analysis. Cognitive Information Processing (CIP) theory was applied as the guiding framework for organising and analysing the data.The career decision-making process of the participants generally followed the stages of decision-making cycle in CIP theory, with a combination of urgent migration decisions and specialisation considerations adding layers of complexity to their career trajectories. Identified challenges encompassed lack of knowledge about oneself and career options, lack of decision-making skills, concerns of contextual complexities that limited the career decision-making process, low motivation and negative thoughts. Specific challenges due to their role as IMSs arose, which were related to career information access, self-capability evaluation, degree accreditation, employment competitiveness and mental states. Participants' proposed strategies were categorised into personal and institutional aspects, providing insights into addressing these challenges.This study substantiates and expands the application of the CIP theory within the sphere of the particular cultural and educational context of IMSs educated in China. It highlights the significance of integrating migration decision-making into career guidance for IMSs, and contributes to the literature by proposing an evidence-based tiered career intervention programme for IMSs.

Epidemiology of cervical cancer and HPV infection in Asia and Oceania

Cancer will continue to be a major source of morbidity and mortality globally during the foreseeable future. Human papillomavirus (HPV)-related cancer is now a serious problem in both women and men. The most common HPV-related cancer is cervical cancer in females and oropharyngeal cancer in males. Eastern Africa has a high age-standardized incidence of HPV-related cancers, followed in order by Southern Africa, Central Africa, and then the rest of Africa. Among Asian and Oceania countries, Fiji, Papua New Guinea, Solomon Islands, Indonesia, Maldives, and Myanmar have extremely high age-standardized incidences and mortality. Oropharyngeal cancer is less common than cervical cancer, but the age-standardized incidence, for both females and males, is higher in Western Europe, Northern Europe, North America, and Australia/New Zealand. Oropharyngeal cancer incidence rates differ significantly from the rates of cervical cancer within the same countries. In Asia and Oceania, the incidence of oropharyngeal cancer is particularly high among females in Bhutan, Bangladesh, and Australia, and it is highest among males in Bangladesh, New Caledonia, Australia, and French Polynesia. To a certain extent, cervical cancer can be reduced through the development of cervical screening programs and improvements in screening uptake. On the other hand, for oropharyngeal cancer, as of yet, no effective means of cancer screening has been established. Widespread uptake of HPV vaccine will contribute to the reduction of HPV-related cancers in Asia and Oceania, but also in the rest of the world.

Areca nut and oral cancer

INTRODUCTION

The association between areca nut consumption and oral cancer has been a subject of increasing concern in global public health.

GLOBAL PERSPECTIVE

Areca nut, often chewed in various forms such as betel quid, is deeply rooted in cultural practices across Asia and other parts of the world. Epidemiological studies consistently reveal a significant correlation between areca nut use and the incidence of oral cancer, emphasizing the need for targeted preventive measures. The complex interplay of areca nut's bioactive compounds, particularly arecoline, with cellular processes, contributes to the initiation and progression of oral carcinogenesis. Mechanistic insights into the genotoxic and cytotoxic effects of its components underscore the urgency for comprehensive public health interventions.

PUBLIC HEALTH

Efforts to address this public health challenge involve multidisciplinary approaches, encompassing education, policy implementation, and behavioral interventions. Understanding the socio-cultural factors influencing areca nut consumption is pivotal for designing effective awareness campaigns and cessation programs.

CONCLUSION

As oral cancer remains a significant global health burden, unraveling the nuanced relationship between areca nut and its role in oral carcinogenesis is crucial for advancing preventive strategies and mitigating the impact of this modifiable risk factor.

Influences of mpox disease perceptions, sources and contents of information exposure on mpox vaccine uptake among gay, bisexual, and other men who have sex with men in Hong Kong, China

BACKGROUND

Following the global mpox outbreak in 2022, multiple regions in Asia have been reporting ongoing mpox cases within high-risk groups, including gay, bisexual, and other men who have sex with men (GBMSM). An optimal level of vaccination rate is essential to prevent further mpox outbreaks. However, no existing studies have examined mpox vaccine uptake among GBMSM in East Asia.

METHODS

A cross-sectional survey was conducted among a sample of 531 GBMSM in Hong Kong, China, between March and October 2023. The study used multivariable logistic regression models to investigate the associations between mpox-related disease perceptions, exposures to sources and contents of mpox-related information, and mpox vaccine uptake.

RESULTS

The prevalence of mpox vaccine uptake among GBMSM in Hong Kong was 21.7%, with 7.7% completing one dose and 13.9% completing two doses. GBMSM who were younger or earning less monthly income were less likely to have been vaccinated. After adjusting for confounding variables, participants who perceived more negative impacts on their lives if they were to contract mpox, more severe symptoms, and a more coherent understanding of mpox were positively associated with mpox vaccine uptake. In addition, more frequent exposure to information through the following sources: TV, newspaper, radio and posters, government websites, news websites or apps, other people's social media, and communication over the phone or face-to-face was positively associated with mpox vaccine uptake. Finally, more frequent exposure to the following information contents: mpox statistics from other countries, the Hong Kong government's responses to mpox cases, negative information about patients with mpox, and information on prevention and treatment of mpox were positively associated with mpox vaccine uptake.

CONCLUSIONS

This study provides timely and evidence-based implications to address health communication and messaging needs in promoting mpox vaccination among GBMSM in Hong Kong, relevant to regions with similar sociocultural contexts.

Prevalence and disease burden of gastroparesis in Asia

Gastroparesis is a gastrointestinal disorder characterized by significant prolongation of gastric emptying time caused by impaired motility of the stomach. Its estimated prevalence is 24.2 per 100 000 people. However, the prevalence of gastroparesis in Asian countries is unknown due to a limited number of epidemiological studies and significant phenotypic variability of the Asian population in these studies. Analysis of previous research on gastroparesis and functional bowel disorders reveals the possibility of an increased prevalence among Asian individuals. A comparison of ethnic constituents between the recent United Kingdom gastroparesis study and its mother database has demonstrated a higher prevalence of gastroparesis among British Asian patients when compared with British Caucasian patients. An estimated gastroparesis prevalence in the Asian population can be calculated by identifying the individuals who are likely to demonstrate a delayed gastric emptying from all diagnosed functional dyspepsia patients. We suggest that gastroparesis tends to be underdiagnosed in Asians due to a lack of studies on gastroparesis in the Asian continent, a lack of knowledge among practitioners, and poor availability of scintigraphy testing as well as limited therapeutic options for this disease. Given the high probability of Asian predominance in gastroparesis and its disease impact on quality of life, epidemiological research focusing on the Asian population is required.

The etiology of pediatric hydrocephalus across Asia: a systematic review and meta-analysis

OBJECTIVE

Despite the high prevalence and significant implications of pediatric hydrocephalus, the etiological distribution of pediatric hydrocephalus across the diverse Asian demographic is poorly understood. This study aimed to inform clinical guidelines and public health decisions by identifying the etiological distribution of pediatric hydrocephalus across Asia.

METHODS

In this systematic review and meta-analysis, the authors searched EMBASE, MEDLINE, CENTRAL, Global Health, Global Index Medicus, and Scopus, with no language restriction, from inception to January 27, 2023. Observational or experimental studies with pediatric data on the causes of hydrocephalus in a country within Asia were included. Pooled proportions of postinfectious hydrocephalus, nonpostinfectious hydrocephalus, and hydrocephalus related to spinal dysraphism were calculated using a random-effects model. Subgroup analyses were performed on prespecified moderators. Methodological study quality was assessed using the modified Newcastle-Ottawa Score and Cochrane's risk-of-bias tool as per the registered protocol on PROSPERO.

RESULTS

The search yielded 5110 results, for which 79 articles were included, with data on 11,529 children from 18 Asian countries. The pooled proportion of nonpostinfectious hydrocephalus was 29.0% (95% CI 22.9-35.5); postinfectious hydrocephalus was 10.7% (95% CI 7.7-14.1); and hydrocephalus secondary to dysraphism was 7.6% (95% CI 5.1-10.5). The pooled proportion of postinfectious hydrocephalus was greatest in lower-middle-income countries (19.2% [95% CI 12.8-26.3]). There was a negative association between the proportion of postinfectious hydrocephalus and Human Development Index (-1.45 [95% CI -2.21 to -0.69]; p < 0.001); urbanization of the country (-0.008 [95% CI -0.012 to -0.004]; p < 0.001); and increasing distance from the equator (-0.016 [95% CI -0.026 to -0.006]; p = 0.002). The pooled proportion of nonpostinfectious hydrocephalus was greatest in high-income countries (36.7% [95% CI 27.6-46.3]). Certain etiologies of pediatric hydrocephalus were more common in different cultural regions, with postinfectious hydrocephalus most common in South Asia (23.2% [95% CI 15.8-31.5]); nonpostinfectious in East Asia (38.3% [95% CI 26.6-50.7]); and dysraphism in West Asia (11.9% [95% CI 6.4-18.8]).

CONCLUSIONS

Geographic and economic characteristics are associated with the etiological distribution of pediatric hydrocephalus in Asia, with implications for prevention and management strategies. The large proportion of hydrocephalus cases in which the etiology was unclear highlights the need for both improved diagnostics as well as clear and strict universal guidelines on the etiological classification of hydrocephalus.

Geospatial and environmental determinants of stunting, wasting, and underweight: Empirical evidence from rural South and Southeast Asia

OBJECTIVE

Child malnutrition, comprising of undernutrition and obesity, is a global concern with severe implications for survival, leading to acute and chronic diseases that adversely affect the productivity of individuals and society. Asia shoulders the greatest burden, with 7 out of 10 undernourished children residing in the region. Despite the decline in global child stunting, particularly in Asia, its prevalence remains significant. In 2017, an estimated 151 million children under five experienced stunting, and an additional 38 million were overweight, with Africa and Asia accounting for 25% and 46% of the global figures, respectively. Therefore, this paper aims to analyze the geospatial and environmental determinants of undernutrition in rural South and Southeast Asia.

METHODS

To explore the geospatial and environmental determinants of undernutrition (stunting, wasting, and underweight), we use Poisson regression and the data from recent rounds of the Demographic and Health Survey (DHS) from India, Bangladesh, Pakistan, Nepal, Cambodia, and Timor-Leste.

RESULTS

This study found a high prevalence of stunting, wasting, and underweight among children aged 0 to 59 months in rural areas of South and Southeast Asia, with considerable variation between countries and clusters/primary sampling units. Results show a positive association between child malnutrition and factors such as maternal illiteracy, unsafe drinking water, and dirty cooking fuel in South and Southeast Asia. Children from impoverished households in India, Pakistan, and Cambodia were disproportionately affected. In addition to socio-economic factors, climatic risks such as temperature increase and rainfall variations also emerged as important determinants of child malnutrition in India, Bangladesh, and Timor-Leste.

CONCLUSIONS

This paper emphasizes the role of environmental and climatic factors on child nutrition, underscoring their significance regardless of socio-economic conditions. As the impacts of climate change continue to intensify, and agrarian societies bear the brunt, these factors will play a critical role in shaping child nutritional outcomes. Thus, amid growing climate change, nutritional security should be prioritized, considering the spatial domain and targeting climate distress areas along with other socio-economic and demographic aspects.

Health-Related Quality of Life Assessment in Prostate Cancer Patient Undergoing Androgen Deprivation Therapy: Real-World Experience in the READT Study

PURPOSE

To investigate the effect of androgen deprivation therapy (ADT) on health-related quality of life (HRQOL) in Asian men with all stages of prostate cancer.

MATERIALS AND METHODS

READT (real-life evaluation of the effect of ADT in prostate cancer patients in Asia) was a multi-center, prospective observational study involving six sites across four Asian populations. We enrolled eligible prostate cancer patients, who opted for ADT alone or in combination without prior neoadjuvant or adjuvant ADT within 12 months. The EuroQoL-5 dimensions, 5 level scale (EQ-5D-5L) utility index scores and visual analog scale (VAS) were evaluated at baseline, month 6 and month 12.

RESULTS

A total of 504 patients were recruited into READT between September 2016 and May 2020 with 52.9% diagnosed with metastatic prostate cancer. The EQ-5D-5L was evaluable in 442/504 (87.7%) of patients. Overall baseline EQ-5D-5L utility index score was 0.924 (interquartile range [IQR] 0.876-1.000). We observed a statistically significant difference in baseline EQ-5D-5L utility index score among different populations with a median EQ-5D-5L utility index score of 1 for Taiwan & Hong Kong, 0.897 for China and 0.838 for Malaysia. Similar trend was observed throughout multiple treatment time-points. Stage IV prostate cancer were significantly associated with a lower baseline EQ-5D-5L utility index score compared to stage I-III prostate cancer, producing a median disutility value of -0.080. Participants had a high median VAS (80, IQR 70-90), indicating good overall health on average during ADT initiation.

CONCLUSIONS

The study highlights the differences in health state utility index scores among various Asian prostate cancer patients receiving ADT at real-world setting. Our findings will be informative and useful in cost-effectiveness evaluation and policy decision making.

A case of lower limb ulcer caused by hydroxyurea in treating primary thrombocytosis

Hydroxyuria is a common medication for treating blood system diseases, but ulcers in the lower limbs caused by this medication are often rare and not often suspected. We reported an elderly patient with lower limb ulcers caused by hydroxyurea treatment for primary thrombocytosis. When hydroxide is used, close observation of skin lesions and prompt handling of any skin disruption should prevent ulcers.

Genomic analysis reveals deep population divergence in the water snake Trimerodytes percarinatus (Serpentes, Natricidae)

Although several phylogeographic studies of Asian snakes have been conducted, most have focused on pitvipers, with non-venomous snakes, such as colubrids or natricids, remaining poorly studied. The Chinese keelback water snake (Trimerodytes percarinatus Boulenger) is a widespread, semiaquatic, non-venomous species occurring in China and southeastern Asia. Based on mitochondrial DNA (mtDNA) and single nucleotide polymorphism (SNP) data, we explored the population genetic structure, genetic diversity, and evolutionary history of this species. MtDNA-based phylogenetic analysis showed that T. percarinatus was composed of five highly supported and geographically structured lineages. SNP-based phylogenetic analysis, principal component analysis, and population structure analysis consistently revealed four distinct, geographically non-overlapping lineages, which was different from the mtDNA-based analysis in topology. Estimation of divergence dates and ancestral area of origin suggest that T. percarinatus originated ~12.68 million years ago (95% highest posterior density: 10.36-15.96 Mya) in a region covering southwestern China and Vietnam. Intraspecific divergence may have been triggered by the Qinghai-Xizang Plateau uplift. Population demographics and ecological niche modeling indicated that the effective population size fluctuated during 0.5 Mya and 0.002 Mya. Based on the data collected here, we also comment on the intraspecific taxonomy of T. percarinatus and question the validity of the subspecies T. p. suriki.

Performance management and policy evaluation of information and communication technology graduate program for developing countries

As an educational aid, the Korean government has developed and funded a graduate-level global information telecommunications technology program (ITTP) for ICT officers in developing countries. Questions have arisen about whether the program can achieve its goals and obtain mutual benefits between Korea and participating nations. Using a total quality management (TQM) framework as a unique case analysis, we evaluated ITTP's resources and performance from 2006 to 2014. Our results show that ITTP has focused on the quantitative promotion of students and alums from various countries and their learning of Korea-centric ICT, policies, and culture. In particular, the Korean government's lax evaluation of ITTP performance has led to weak responsibility, ambiguous task identity, missed opportunities for self-improvement, and low participation among students and stakeholders. These findings highlight the need for graduate programs and their stakeholders to reinforce internal and external evaluations of the program's performance and provide feedback for reciprocal development.

The modified Rajan's heart failure risk score predicts all-cause mortality in patients hospitalized for heart failure with reduced ejection fraction: a retrospective cohort study

Background

The dimensionless Rajan's heart failure (R-hf) risk score was proposed to predict all-cause mortality in patients hospitalized with chronic heart failure (HF) and reduced ejection fraction (EF) (HFrEF).

Purpose

To examine the association between the modified R-hf risk score and all-cause mortality in patients with HFrEF.

Methods

Retrospective cohort study included adults hospitalized with HFrEF, as defined by clinical symptoms of HF with biplane EF less than 40% on transthoracic echocardiography, at a tertiary centre in Dalian, China, between 1 November 2015, and 31 October 2019. All patients were followed up until 31 October 2020. A modified R-hf risk score was calculated by substituting brain natriuretic peptide (BNP) for N-terminal prohormone of BNP (NT-proBNP) using EF× estimated glomerular filtration rate (eGFR)× haemoglobin (Hb))/BNP. The patients were stratified into tertiles according to the R-hf risk score. The measured outcome was all-cause mortality. The score performance was assessed using C-statistics.

Results

A total of 840 patients were analyzed (70.2% males; mean age, 64±14 years; median (interquartile range) follow-up 37.0 (27.8) months). A lower modified R-hf risk score predicted a higher risk of all-cause mortality, independent of sex and age [1st tertile vs. 3rd tertile: adjusted hazard ratio (aHR), 3.46; 95% CI: 2.11-5.67; P<0.001]. Multivariate Cox regression analysis indicated that a lower modified R-hf risk score was associated with increased cumulative all-cause mortality [univariate: (1st tertile vs. 3rd tertile: aHR, 3.45; 95% CI: 2.11-5.65; P<0.001) and multivariate: (1st tertile vs. 3rd tertile: aHR 2.21, 95% CI: 1.29-3.79; P=0.004)]. The performance of the model, as reported by C-statistic was 0.67 (95% CI: 0.62-0.72).

Conclusion

The modified R-hf risk score predicted all-cause mortality in patients hospitalized with HFrEF. Further validation of the modified R-hf risk score in other cohorts of patients with HFrEF is needed before clinical application.

Newborns with congenital complete heart block: Advice for perinatal care providers

Congenital complete heart block (CCHB) is a rare, but a potentially life-threatening manifestation of autoimmune diseases in neonates. Bradycardia in CCHB can be misdiagnosed as foetal distress in utero and thus precipitating a Caesarean section. We report a case series of three neonates with bradycardia without any electrolyte abnormalities and structurally normal hearts with favourable outcomes.

Retinoblastoma in Asia: Clinical Presentation and Treatment Outcomes in 2112 Patients from 33 Countries

PURPOSE

To describe the clinical presentation and treatment outcomes of children who received a diagnosis of retinoblastoma in 2017 throughout Asia.

DESIGN

Multinational, prospective study including treatment-naïve patients in Asia who received a diagnosis of retinoblastoma in 2017 and were followed up thereafter.

PARTICIPANTS

A total of 2112 patients (2797 eyes) from 96 retinoblastoma treatment centers in 33 Asian countries.

INTERVENTIONS

Chemotherapy, radiotherapy, enucleation, and orbital exenteration.

MAIN OUTCOME MEASURES

Enucleation and death.

RESULTS

Within the cohort, 1021 patients (48%) were from South Asia (SA), 503 patients (24%) were from East Asia (EA), 310 patients (15%) were from Southeast Asia (SEA), 218 patients (10%) were from West Asia (WA), and 60 patients (3%) were from Central Asia (CA). Mean age at presentation was 27 months (median, 23 months; range, < 1-261 months). The cohort included 1195 male patients (57%) and 917 female patients (43%). The most common presenting symptoms were leukocoria (72%) and strabismus (13%). Using the American Joint Committee on Cancer Staging Manual, Eighth Edition, classification, tumors were staged as cT1 (n = 441 [16%]), cT2 (n = 951 [34%]), cT3 (n = 1136 [41%]), cT4 (n = 267 [10%]), N1 (n = 48 [2%]), and M1 (n = 129 [6%]) at presentation. Retinoblastoma was treated with intravenous chemotherapy in 1450 eyes (52%) and 857 eyes (31%) underwent primary enucleation. Three-year Kaplan-Meier estimates for enucleation and death were 33% and 13% for CA, 18% and 4% for EA, 27% and 15% for SA, 32% and 22% for SEA, and 20% and 11% for WA (P < 0.0001 and P < 0.0001), respectively.

CONCLUSIONS

At the conclusion of this study, significant heterogeneity was found in treatment outcomes of retinoblastoma among the regions of Asia. East Asia displayed better outcomes with higher rates of globe and life salvage, whereas Southeast Asia showed poorer outcomes compared with the rest of Asia.

Disability Among Older Immigrants in the United States: Exploring Differences by Region of Origin and Gender

Rapid aging in American society will be disproportionately concentrated among the foreign-born. Immigrants in the United States (U.S.) are a heterogeneous population, yet little is known regarding their differences in disability later in life by region of origin. We use data from the National Health Interview Survey on respondents ages 60+ (n = 313,072) and employ gender-specific logistic models to predict reports of any activity of daily living (ADL) disability. After accounting for socioeconomic factors, compared to their U.S.-born non-Hispanic (NH) White counterparts, the odds of reporting ADL disability were higher among U.S.-born respondents that are Hispanic, NH Black, and NH Multiracial as well as respondents with Mexican, Puerto Rican, Cuban, Russian/former Soviet, Middle Eastern, East Asian, and South Asian origins. Also, Dominican, African, and Southeast Asian women-and European men-reported high odds of ADL disability. Our results highlight heterogeneity in the disability profiles of foreign-born older adults in the U.S..

The first complete mitochondrial genome data of the Afghan pika Ochotona rufescens (Lagomorpha, Ochotonidae), near the type locality

The Afghan pika Ochotona rufescens (Gray, 1842) is widely distributed across the mountains of Afghanistan, Iran, Pakistan, and southwestern Turkmenistan, most often at elevations between 2,000 and 3,000 m. Here we present, for the first time, the complete mitochondrial genomes of two specimens of the nominotypical subspecies Ochotona rufescens rufescens, de novo assembled from Illumina short reads of fragmented probe-enriched DNA. The lengths of the circular mitogenomes are 16,408 bp and 16,407 bp, respectively. Both mitogenomes contain 13 protein-coding genes (PCGs), two ribosomal RNAs (16S rRNA and 12S rRNA), 22 transfer RNA genes, and a control region. The gene NAD6 and the tRNA (Gln), tRNA (Ala), tRNA (Asn), tRNA (Cys), tRNA (Tyr), tRNA (Ser), tRNA (Glu), and tRNA (Pro) are encoded on the light strand while the rest are encoded on the heavy strand. The overall nucleotide composition was ∼30% for A, 25% for T, 15% for G, and 29% for C. The mitogenome data are available in the GenBank under the accession numbers ON859136 and ON859137.

Clinical and antimicrobial susceptibility profile of typhoid fever in children in the era of antibiotic resistance

Enteric fever remains a significant public health problem in low- and middle-income countries with further challenges from emerging antimicrobial resistance. Our prospective study evaluated the current clinical and antimicrobial susceptibility profile of enteric fever in 88 children and compared it to previously established literature. Enteric fever usually presents with nonspecific signs and symptoms, with predominant respiratory complaints. A paradigm shift in the antimicrobial sensitivity pattern has been noted, with increasing resistance for first-line antibiotics and older antibiotics such as ampicillin, cotrimoxazole, and chloramphenicol showing good sensitivity. Thus, the introduction of the latter merits consideration.

- Invited Review - Current status, challenges and prospects for pig production in Asia

Asia is not only the primary region for global pig production but also the largest consumer of pork worldwide. Although the pig production in Asia has made great progress in the past, it still is confronted with numerous challenges. These challenges include: inadequate land and feed resources, a substantial number of small-scale pig farms, escalating pressure to ensure environmental conservation, control of devastating infectious diseases, as well as coping with high temperatures and high humidity. To solve these problems, important investments of human and financial capital are required to promote large-scale production systems, exploit alternative feed resources, implement precision feeding, and focus on preventive medicine and vaccines as alternatives to antibiotics, improve pig breeding, and increase manure recycling. Implementation of these techniques and management practices will facilitate development of more environmentally-friendly and economically sustainable pig production systems in Asia, ultimately providing consumers with healthy pork products around the world.

Two new species of the Cnemaspisgalaxia complex (Squamata, Gekkonidae) from the eastern slopes of the southern Western Ghats

Two new species allied to Cnemaspisgalaxia are described from the eastern slopes of the south Western Ghats, Tamil Nadu, India. Both new species are members of the ornata subclade within the beddomei clade. The two new species can be easily distinguished from all other members of the beddomei clade and each other by a combination of nonoverlapping morphological characters such as small body size, distinct colouration of both sexes, the number of dorsal tubercles around the body, the number or arrangement of paravertebral tubercles, the number of midventral scales across the belly and longitudinal ventral scales from mental to cloaca, besides uncorrected pairwise ND2 and 16S sequence divergence of ≥ 7.4% and ≥ 2.7%. The two new species are distributed from low elevation, deciduous forests of Srivilliputhur, and add to the five previously known endemic vertebrates from Srivilliputhur-Megamalai Tiger Reserve.

Haemophilia care in Asia: Learning from clinical practice in some Asian countries

BACKGROUND

The healthcare systems in Asia vary greatly due to the socio-economic and cultural diversities which impact haemophilia management.

METHODS

An advisory board meeting was conducted with experts in haemophilia care from Asia to understand the heterogeneity in clinical practices and care provision in the region.

FINDINGS

The overall prevalence of haemophilia in Asia ranges between 3 and 8.58/100,000 patients. Haemophilia A was more prevalent as compared to haemophilia B with a ratio of around 5:1. There is under-diagnosis in the region due to lack of diagnosis, registries and/or lack of appropriate facilities in suburban areas. Most patients are referred to the haematologists by their families or primary care physicians, while some are identified during bleeding episodes. Genetic testing faces obstacles like resource constraints, services available at limited centres and unwillingness of patients to participate. Prophylaxis is offered for people with haemophilia (PWH) with a severe bleeding phenotype. Recombinant factors are approved in most countries across the region and are the preferred therapy. The challenges highlighted for not receiving a high standard of care include patients' reluctance to use an intravenous treatment, poor patient compliance due to frequency of infusions, budget constraints and lack of funding, insurance, availability and accessibility of factor concentrates. Prevalence of neutralizing antibodies ranged from 5% to 20% in the region. Use of immune tolerance induction and bypassing agents to treat inhibitors depends on their cost and availability.

CONCLUSION

Haemophilia care in Asia has evolved to a great extent. However, some challenges remain for which a strategic approach along with multi-stakeholder involvement are needed.

Psychometric properties of the World Health Organization WHOQOL-AGE Scale in Singapore

WHOQOL-AGE is a promising quality of life (QOL) tool that has not been fully validated in Asia. The present study aimed to verify its factor structure and psychometric properties among community-dwelling older adults in Singapore. This study was cross-sectional and used data (N = 593) from the Community Health and Intergenerational study that interviewed older adults between 2018 and 2021. Confirmatory factor analysis (CFA) was used to examine the factor structure of the WHOQOL-AGE, and Cronbach's alpha coefficients were employed to examine internal consistency. Spearman's rho correlations coefficients between WHOQOL-AGE and other related scales (Satisfaction with Life and the Friendship) examined convergent validity. A Pearson's correlation coefficient between WHOQOL-AGE and compassion scale examined discriminant validity. An independent t test was used to demonstrate known-groups validity, examining differences in QOL scores between individuals with and without chronic medical conditions. Findings supported a bifactor model with more satisfactory goodness-of-fit indices than the original two-factor model and the two-correlated factor model. WHOQOL-AGE showed adequate internal consistency (Cronbach's alpha coefficients > .70). Good convergent validity was demonstrated by moderate-to-large correlations between WHOQOL-AGE and satisfaction with life (rs = .54) as well as social connectedness (rs = .33). Discriminant validity was shown by low correlations between WHOQOL-AGE and compassion (r = .19). Findings also indicated good known-groups validity (p < 0.01). The WHOQOL-AGE showed promising psychometric properties using an Asian convenience sample and can be useful in large-scale studies or busy clinical settings.

Discrepancies Among Hospitals and Regions in the Provision of Low-Value Care

BACKGROUND

Low-value care is a critical issue in terms of patient safety and fiscal policy; however, little has been known in Asia. For the purpose of better understanding the extent of low-value care on a national level, the utilization, costs and associated characteristics of selected international recommendations were assessed in this study.

METHODS

This retrospective cohort study used the National Health Insurance claims data during 2013-2017 to evaluate the low-value care utilization. Adult beneficiaries who enrolled in the National Health Insurance program and received at least one of the low-value services in hospitals were included. We measured seven procedures derived from the international recommendations at the hospital level, and a composite measure was created by summing the total utilization of selected services to determine the overall prevalence and corresponding cost. The generalized estimating equation model was adopted to estimate the association.

RESULTS

A total of 1,970,496 episodes of low-value care was identified among 1,218,146 beneficiary-year observations and 2,054 hospital-year observations. Overall, the utilization rate of the composite measure increased from 150.70 to 186.23 episodes per 10,000 beneficiaries with the growth in cost from US$5.40 to US$6.90 million. Low-value care utilization was proportional to the volume of outpatient visits and length of stay. Also, hospitals with a large volume of outpatient visits (aOR [95% CI], 2.10 [1.26 to 3.49] for Q2- Q3, 2.88 [1.45 to 5.75] for ≥Q3) and a higher proportion of older patients (aOR [95% CI], 1.06 [1.02 to 1.11]) were more likely to have high costs.

CONCLUSION

The utilization and corresponding cost of low-value care appeared to increase annually despite the relatively lower prevalence compared to other countries. Multicomponent interventions such as recommendations, de-implementation policies and payment reforms are considered effective ways to reduce low-value care. Repeated measurements would be needed to evaluate the effectiveness of interventions.

Country risk, global uncertainty, and firms' cash holdings: Do the role of law, culture, and financial market development matter?

To the extent of our knowledge, there is a gap in scrutinizing the impacts of the country's risk and global uncertainty on Asian firms' cash holdings. Therefore, this work aims to shed light on this gap by choosing 989 listed non-financial Asian firms and performing both the static (fixed-effects) and dynamic (Difference-GMM and System-GMM) panel data methods between 2008 and 2020. The findings reveal that an increase in a country's risk and global uncertainty stimulates firms to stockpile more cash though the impact of country risk is more pronounced. Likewise, the results underscore that among the country risk factors, firms have more precautionary motives to stockpile more cash with increases in financial and political instability while they hold more cash with rises in economic stability. Remarkably, the results emphasize that the impacts of country risk and global uncertainty on cash holdings are more prominent in environments characterized by common-law legal origin, high uncertainty avoidance cultures, and less financial market development. Moreover, the results reveal that firm-specific factors including growth opportunity, leverage, profitability, dividend, and size have an important role in shaping Asian firms' cash holdings policy.

"For me, it is for longevity and making sure I am fit and around for my children": exploring motivations and barriers for weight management among minoritised communities in Medway, England

BACKGROUND

Migration-related changes in dietary patterns and other structural and individual factors affect weight-related health practices of individuals migrating from low-and-middle-income to high-income countries. Thus, individuals of ethnically diverse backgrounds may be disproportionately affected by poorer health outcomes, including weight-related health issues. Understanding how this community could be supported to adopt weight-related healthy practices such as optimum dietary and exercise behaviour is an important issue for public health research. Against this backdrop, we explored structural and individual factors that facilitate and constrain the uptake of weight management services among members of minority ethnic communities in Medway, England.

METHODS

Data were collected from audio-recorded interviews with 12 adult community members from minoritised ethnic communities using a semi-structured interview guide. Participants were recruited through a purposive and convenient sampling technique. Generated data were transcribed, coded into NVivo and analysed using the reflexive thematic analytical technique.

RESULTS

Results showed that social support and health benefits of weight management were the main motivating factors for weight management among the study participants. Conversely, systemic barriers, family commitment and caring responsibilities, changes in dietary patterns post-migration and cultural norms were major factors constraining participants from adopting weight management behaviours.

CONCLUSION

The results of this study indicate that structural and person-level factors serve as both facilitators and barriers to weight management among ethnically diverse communities in Medway, England. While our study is exploratory and opens doors for more studies among the population, we conclude that these minoritised communities could benefit from more equitable, tailored weight management programmes to support them in adopting weight-related practices.

It is characterized by the approximately rectangular aedeagus, which is longitudinally split in the middle, with the apices slightly bending to the outside, making it into the shape of a hook; bilobed aedeagus is very closely connected. The description is provided using scanning electron microscopes, light microscopes, and camera lucida drawing. The specimens were collected from woods near a pond in Liping County, Guizhou Province. We provide both keys to male and female of Forcipomyia (Lasiohelea) taiwana species group in China.

Disparities in pediatric anaphylaxis triggers and management across Asia

BACKGROUND

The epidemiology and management of anaphylaxis are not well-reported in Asia.

METHODS

A regional pediatric anaphylaxis registry was established by the Asia-Pacific Research Network for Anaphylaxis (APRA), using standardized protocols for prospective data collection, to evaluate the triggers and management of anaphylaxis in the Asia-Pacific region. Pediatric patients below 18 years presenting with anaphylaxis across four Asian countries/cities (Thailand, Singapore, Hong Kong (HK), and Qingdao) were included. Allergen triggers, symptoms, anaphylaxis severity, and management were compared.

RESULTS

Between 2019 and 2022, 721 anaphylaxis episodes in 689 patients from 16 centers were identified. The mean age at anaphylaxis presentation was 7.0 years (SD = 5.2) and 60% were male. Food was the most common trigger (62%), particularly eggs and cow's milk in children aged 3 years and below. In school-age children, nut anaphylaxis was most common in HK and Singapore, but was rare in the other countries, and wheat was the top allergen in Bangkok. Shellfish anaphylaxis was most common in children aged 7-17. Adrenaline was administered in 60% of cases, with 9% given adrenaline before hospital arrival. Adrenaline devices were prescribed in up to 82% of cases in Thailand but none in Qingdao.

CONCLUSIONS

The APRA identified food as the main trigger of anaphylaxis in children, but causative allergens differed even across Asian countries. Fewer than two-thirds of cases received adrenaline treatment, pre-hospital adrenaline usage was low, and adrenaline device prescription remained suboptimal. The registry recognizes an unmet need to strengthen anaphylaxis care and research in Asia-Pacific.

Prescribing Patterns and Outcomes of Edoxaban in Atrial Fibrillation Patients From Asia - One-Year Data From the Global ETNA-AF Program

Background: This study reports prescribing patterns and the 1-year effectiveness and safety of edoxaban in an Asian cohort of Edoxaban Treatment in routiNe clinical prActice (ETNA)-Atrial Fibrillation (AF) patients. Methods and Results: The Global ETNA-AF program integrates prospective, observational, noninterventional regional studies, collecting data on characteristics and clinical outcomes of patients with AF receiving edoxaban for stroke prevention. Baseline characteristics, medical history, and 1-year clinical event rates were assessed in patients from South Korea, Taiwan, Hong Kong, and Thailand. Clinically relevant events assessed at 12 months included all-cause death, cardiovascular death, ischemic and hemorrhagic stroke, systemic embolic events (SEEs), bleeding, and net clinical outcome (NCO). Overall, 3,359 patients treated with edoxaban 60 or 30 mg once daily completed 1-year follow-up; 70.9% of patients received recommended dosing according to local labels. Baseline mean±standard deviation age was 71.7±9.6 years, CHA2DS2-VASc score was 3.1±1.5, and modified HAS-BLED score was 2.3±1.1. Mean age and sex were similar across countries/regions. The 1-year event rate for all-cause death was 1.8%; major bleeding, 1.3%; ischemic stroke, 1.1%; cardiovascular mortality, 0.7%; hemorrhagic stroke, 0.3%; SEEs, 0%; and NCO, 4.1%; with differences observed between countries/regions and dosing groups. Conclusions: Most Asian patients with AF were prescribed recommended edoxaban dosing in routine care settings. At 1-year follow-up, this analysis supports the effectiveness and safety of edoxaban in these patients.

Asia's Growing Contribution to Obesity Surgery Research: A 40-year Bibliometric Analysis

Bariatric metabolic surgery's global research interest is growing, particularly in Asia due to its high obesity rates. This study focuses on Asia, especially China, analyzing 3904 publications (1221 from China) from 1980 to 2022. Research output accelerated until the COVID-19 pandemic, driven by economic growth and rising obesity rates. China led contributions from 2010, but Western Asia led when adjusted for population. An intra-regional research collaboration network emerged, driven by geographic proximity and similar economic environments. Keyword analysis highlighted emerging topics like "laparoscopic sleeve gastrectomy" and "non-alcoholic fatty liver disease," indicating a shift in focus. The study recommends disseminating research in top-tier journals to enhance visibility and impact.

Prevalence of Giardia duodenalis among Asian children: a systematic review and meta-analysis

Giardia duodenalis is one of the major causes of diarrhea among children. We performed a systematic review and meta-analysis to assess the prevalence of G. duodenalis and associated risk factors among Asian children. We searched online databases (PubMed, Scopus and Web of Science) and Google Scholar search engine for studies published from 1 January 2000 to 15 March 2022 that measured the prevalence of G. duodenalis among Asian children. Accordingly, the pooled prevalence and 95% CIs were estimated using a random-effects meta-analysis model for the included studies. A total of 182 articles from 22 Asian countries met the inclusion criteria. The pooled prevalence of G. duodenalis infection among Asian children was estimated as 15.1% (95% CI 14.1 to 16%). The highest and lowest pooled prevalence values of G. duodenalis infection were estimated for Tajikistan and China as 26.4% (95% CI 22.9 to 30%) and 0.6% (95% CI 0.001 to 1.02%), respectively. The infection had a higher prevalence in males than in females (OR=1.24; 95% CI 1.16 to 1.31; p<0.001), which was statistically significant. Giardiasis is common among Asian children, hence, a prevention and control scheme of this protozoan in children should be considered by health officials and health policymakers, especially in Asian countries where the prevalence is highest.

Asia Core Dossier: Standardizing CMC Requirement to Facilitate Best Case Submissions in Asia

When the regulatory requirements are converged or harmonized, the country-specific variance of countries is often reduced or omitted, and this facilitates the possibility of preparing a core dossier that caters to multiple countries. When such options of a core dossier are acceptable to multiple countries, the resource required to prepare the dossier and the time taken to prepare it is also reduced, thus eliminating resource constraints in supporting dossier planning and preparation and indirectly facilitating earlier submission in countries. In this paper, the authors have illustrated a process applied to standardize the dossier requirements amongst selected countries in Asia, producing an output of a core dossier that applies to four submission types amongst these countries. The core dossier adopts the International Council for Harmonization-Common Technical Dossier format as a reference. Main focus is the standardization of format and requirements within the Module 3 or Chemistry Manufacturing Controls sections of the dossier, which from the authors' organizational experience usually notes a higher variances and country-specific elements. Development of the dossier standardization process is due to an internal hurdle within the authors' organization, where global resource constraints and prioritizations of dossier preparation and compliance review process needed to be improved to facilitate earlier or near-simultaneously submissions in the majority of the Asia countries. The paper demonstrates an assessment of the dossier components and standardization to assemble a fit-for-purpose core dossier termed 'Asia Core Dossier' (ACD). ACD has been successfully implemented within the authors' organization to reduce country-specific requirements and facilitate earlier (fit for strategy) submissions in the selected Asia countries. The paper also discusses the tangible benefits of the authors' experiences from utilizing the ACD. Regulatory professionals in different organizations could reference the ACD as a template for preparing a simplified and efficient dossier and as a relevant component of Good Submission Practice (GSubP).

The research study also explores the various key challenges faced by the medical libraries in Bangladesh and finally provides necessary recommendations like a sufficient library budget, implementation of  an Integrated Library System (ILS), skilled manpower, more participation in information networking and resource sharing, sound ICT environment, online collection development for the overall development of medical libraries in Bangladesh.

Towards a greener future: examining carbon emission dynamics in Asia amid gross domestic product, energy consumption, and trade openness

The purpose of this study is to examine the impact of gross domestic product, energy consumption, and trade openness on carbon emission in Asia. Among the 48 countries in Asia, 42 were included in the analysis, spanning a period of 20 years. Given that Asia is the predominant contributor, accounting for 53% of global emissions as of 2019, a comprehensive examination at both continental and individual country levels becomes imperative. Such an approach aligns with local, regional, and global development agendas, contributing directly and indirectly to climate change mitigation. The analytical techniques employed in this study encompassed panel regression and multiple linear regression, illuminating the specific contributions of each country to the study variables and their impact on carbon emissions. The findings suggest that gross domestic product (13 out of 42 countries), energy consumption (21 out of 42 countries), and trade openness (eight out of 42 countries) have a highly significant impact (p < 0.01) on carbon emissions in Asia. Energy consumption plays a vital role in increasing carbon emissions in Asia, driven by rising populations, urbanisation, and oil and gas production. Policymakers can take several actions such as adopting a carbon pricing system, using sustainable transportation, renewable energy development, and international cooperation within Asia to reach the goal of being carbon neutral by 2050.

Thigh muscle thickness on ultrasonography for diagnosing sarcopenia: The Kyoto-Kameoka study

AIM

The Asian Working Group for Sarcopenia 2019 consensus reported that evidence for the diagnosis of sarcopenia based on ultrasonography findings is lacking. The revised European Working Group on Sarcopenia in Older People consensus stated that ultrasonography is reliable and valid for assessing muscle size in older adults. The present study aimed to determine the predictive accuracy of ultrasonography for sarcopenia in older adults in Japan.

METHODS

A total of 1229 participants aged 65-91 years were included in this cross-sectional study. The thickness of the anterior compartment of the right thigh was assessed using B-mode ultrasonography. The measurement position was at the midpoint of the thigh. In addition, the grip strength, gait speed, Five-Time Sit-to-Stand Test, Short Physical Performance Battery score and skeletal muscle mass index were evaluated. Sarcopenia was diagnosed based on the Asian Working Group for Sarcopenia 2019 algorithm. We calculated the area under the receiver operating characteristic curve.

RESULTS

The area under the receiver operating characteristic curves (95% confidence intervals) and cutoff values for the thigh muscle thickness in sarcopenia were 0.901 (0.856-0.946) and 4.0 cm in men, respectively, and 0.923 (0.851-0.995) and 3.1 cm in women, respectively. The area under the receiver operating characteristic curve for each subdomain of sarcopenia, such as grip strength and gait speed, ranged from 0.618 to 0.872.

CONCLUSIONS

In the present study, the suggested cutoff mid-thigh muscle thicknesses on ultrasonography for predicting sarcopenia were 4.0 cm in men and 3.1 cm in women. Geriatr Gerontol Int 2024; 24: 156-161.

"Mother's milk": Is there a social reversal in breastfeeding practices along with economic development?

Previous studies suggest that macro- and micro-level factors jointly influence breastfeeding (BF) practices, but empirical evidence on the dynamics of such interactions along with the process of a country's economic development remains limited. Based on 42 Demographic Health Surveys (DHS) conducted in 15 Asian countries with a large time window (1990-2017), we thus test the existence of a reversal in the association between household wealth and BF practices throughout the development process. Four BF indicators (early initiation of BF, exclusive BF, continued BF at one year and two years) are examined, along with a standardized asset-based household wealth index allowing for cross-wave and cross-country comparisons. To highlight the dynamics of the wealth-BF association, we carry out econometric estimations, including interaction terms between household wealth and the country's level of economic development (low, medium, and high) or time. Instrumental variable estimations are also performed to limit suspected endogeneity issues. Our results confirm a transition in the wealth gradient of exclusive BF and continued BF in Asian countries. More precisely, while these practices are pro-poor in the poorest countries of the sample, they progressively spread to wealthier households along with the level of economic development. For exclusive BF, this transition has resulted in a reversal of the wealth gradient at the end of the period (i.e., exclusive BF prevalence among the rich overpassing that of the poor). We fail, however, to observe this kind of transition for early initiation of BF, this practice remaining pro-poor, whatever the level of economic development. To sum up, our results provide robust evidence of a transition in the wealth gradient of some BF practices along with economic development and time, and thus largely echo the literature exploring the social reversal hypothesis in the case of non-communicable diseases.

Malaysian joint societies' consensus recommendations on diagnosis and management of disorders of esophagogastric junction outflow

Disorders of esophagogastric junction (EGJ) outflow, including achalasia and EGJ outflow obstruction, are motility disorders characterized by inadequate relaxation of lower esophageal sphincter with or without impaired esophageal peristalsis. Current guidelines are technical and less practical in the Asia-Pacific region, and there are still massive challenges in timely diagnosis and managing these disorders effectively. Therefore, a Malaysian joint societies' task force has developed a consensus on disorders of EGJ outflow based on the latest evidence, while taking into consideration the practical relevance of local and regional context and resources. Twenty-one statements were established after a series of meetings and extensive review of literatures. The Delphi method was used in the consensus voting process. This consensus focuses on the definition, diagnostic investigations, the aims of treatment outcome, non-surgical or surgical treatment options, management of treatment failure or relapse, and the management of complications. This consensus advocates the use of high-resolution esophageal manometry for diagnosis of disorders of EGJ outflow. Myotomy, via either endoscopy or laparoscopy, is the preferred treatment option, while pneumatic dilatation can serve as a secondary option. Evaluation and management of complications including post-procedural reflux and cancer surveillance are recommended.

Understanding the Food Environment and Its Impact on Diet and Health in Asia: A Scoping Review

Food environment (FE), an interface where people interact with a broader food system, is critical to health. Understanding the Asian FE may help to tackle the "triple burden of malnutrition" through informed research and policy. This review identifies FE domains assessed in the Asian context and collates the tools/measures used in these evaluations. We further synthesized the reported associations of FE with diet and health outcomes and identified knowledge gaps. Forty-two articles were reviewed (East Asia, n = 25, 60%; South Asia, n = 8, 19%; and Southeast Asia, n = 9, 21%). The results showed that FE was frequently examined in children, adolescents, or adults, but data were scarce in older adults. Food availability (n = 30) and accessibility (n = 19) were popularly studied domains. Furthermore, FE was measured using geographic information systems (n = 18), market (n = 7), or stakeholder (n = 21) surveys. Twenty-eight (67%) articles assessed associations of FE exposures with diet (n = 12) and health (n = 21). Increased food availability and accessibility were associated with poorer dietary and health outcomes despite nonexisting validity and reliability reporting in 62% of articles. Limited high-quality studies emphasize the need for harmonized definitions, better study designs, and validated FE measures/tools in Asia. Improving the quality of FE research is critical to designing effective interventions to improve public health nutrition in Asia.

Diversity in Oncology Clinical Trials: Current Landscape for Industry-Sponsored Clinical Trials in Asia

INTRODUCTION

There has been a growing recognition on the importance of diversity in clinical trials. Existing research has highlighted a significant demographic imbalance. Amidst this renewed focus on diversity, it is crucial to acknowledge that Asia comprises over half of the world's population. Given the region's demographic significance, we sought to compare various characteristics and growth rates for trials with sites in Asia against those without any sites in Asia.

METHODS

We performed comprehensive analyses of industry-sponsored phase 2 and 3 oncology trials registered at Clinicaltrials.gov, using drugs or biologics as investigational agents and executed between 1 January 2018 and 31 December 2022. We applied the compound annual growth rate (CAGR) as an analytical tool to track the trial growth rates over this 5-year period.

RESULTS

We identified 894 industry-sponsored phase 2 and 3 cancer studies with available study location data. Out of these, 415 trials (46.42%) had study sites in Asia. Notably, these trials with sites in Asia were also more likely to be phase 3 trials (39.76% vs 6.47%, p < 0.001), include female and paediatric populations, and be randomised trials. Interestingly, lung and stomach cancers were more commonly studied in these trials, while myeloma was less commonly studied. The number of trial sites for liver cancer was not significantly higher for Asia, even though the incidence of the disease is much higher in this region. Despite an overall declining trend in the number of clinical trials in the last 5 years, we observed a transitional positive increase in the CAGR from 2020 to 2021 for trials with sites in Asia. However, East Asia, specifically China, exhibited a disproportionate overrepresentation in these trials.

CONCLUSIONS

There are notable characteristics of clinical trials with sites in Asia. Comprehending these disparities may aid in the strategic planning to enhance a balanced representation of ethnicities in trials.
