    The putative H. pylori pathogenicity-associated factor dupA has been associated with IL-8 induction in vitro, and duodenal ulcer (DU) and gastric cancer (GC) development in certain populations, but this association is inconsistent between studies. We aimed to investigate dupA prevalence in clinical isolates from Sweden, Australia and from ethnic Chinese, Indians and Malays resident in Malaysia and Singapore and to examine the association with DU and GC. In addition we investigated the sequence diversity between isolates from these diverse groups and compared the level of IL-8 secretion in isolates possessing and lacking dupA.

    The firefly genus Luciola sensu McDermott contains 282 species that are distributed across major parts of Asia, Europe, Africa, Australia, and the Pacific islands. Due to phenotypic similarities, species identification using external morphological characters can be unreliable for this group. Consequently, decades of piecemeal taxonomic treatments have resulted in numerous erroneous and contentious classifications. Furthermore, our understanding of the group's evolutionary history is limited due to the lack of a robust phylogenetic framework that has also impeded efforts to stabilize its taxonomy. Here, we constructed molecular phylogenies of Luciola and its allies based on combined mitogenomes and Cytochrome c oxidase subunit 1 (COX1) sequences including a newly sequenced mitogenome of an unidentified taxon from Singapore. Our results showed that this taxon represents a distinct and hitherto undescribed evolutionary lineage that forms a clade with L. filiformis from Japan and L. curtithorax from China. Additionally, the Singaporean lineage can be differentiated from other congeners through several external and internal diagnostic morphological characters, and is thus described herein as a new species. Our phylogeny also strongly supported the paraphyly of Luciola with regard to L. cruciata and L. owadai, which were inferred to be more closely related to the genus Aquatica as opposed to other members of Luciola sensu stricto. The genus Hotaria was inferred as a derived clade within Luciola (sister to L. italica), supporting its status as a subgenus of Luciola instead of a distinct genus. This is the first time since 1909 that a new species of luminous firefly has been discovered in Singapore, highlighting the need for continued biodiversity research, even in small, well-studied and highly developed countries, such as Singapore.

    Background: It was reported that opioid consumption in developing countries was stagnated or decreased, but precise data on the consumption are unclear. This study examined the trends and patterns of opioid consumption in Malaysia and other four Southeast Asian countries.

    Materials and Methods: Data of five strong opioids consumption (morphine, oxycodone, fentanyl, pethidine, and methadone) between 2005 and 2014 from Malaysia, Singapore, Indonesia, Thailand, and Vietnam were extracted from the Pain and Policy Studies Group. Defined daily doses per 1000 inhabitants per day (DDD/1000 inhabitants/day) was used for calculating the annual amount of opioid use.

    Results: The total consumption of five strong opioids was increased in all five Southeast Asian countries during a 10-year study period. Malaysia was recorded with the largest increase of the opioid consumption (993.18%), followed by Indonesia (530.34%), Vietnam (170.17%), Singapore (116.16%), and Thailand (104.66%). Malaysia also had the highest total strong opioid consumption (11.2 DDD/1000 inhabitants/day), primarily for methadone. Among the opioids used for pain management, fentanyl was primarily used in Malaysia and Singapore but the greatest increase in these two countries was for oxycodone. Fentanyl was also primarily used in Indonesia while morphine was predominantly used in Thailand and Vietnam.

    Conclusion: Growing trends of strong opioids consumption in all five Southeast Asian countries demonstrated in this study may indicate improved access to opioid analgesics in these countries. Given the increasing trends, it is important to ensure that the utilization of opioids is according to the guideline to prevent the negative consequences of opioids particularly when used in chronic non-cancer pain.

    Oriental giant squirrels are tree squirrels classified under family Ratufinae. In India, there are three species of genus Ratufa, i.e. Ratufa bicolor, Ratufa macroura and Ratufa indica. They are also distributed in South and Southeast Asia. However Ratufa indica is endemic to India. The fourth species Ratufa affinis is restricted to Maritime Southeast Asia (East Malaysia, Indonesia, Brunei and Thailand) and probably in Singapore. The species is near threatened .The species R.macroura is endemic to South Asia. Forests of South and Southeast Asia are hotspots of squirrel diversity but at the same time they are at a high risk of extinction because of high deforestation rate and habitat fragmentation. The present molecular study is the first study of the species of Ratufa for their identification. In this study old taxidermy samples were used for amplification of 12SrRNA and Cytochrome b genes. Maximum likelihood and neighbor-joining methods were used to delineate the species by using MEGA 6 and also for molecular analysis for variable, conserved, parsimony and singleton sites. Similarities between species through BLAST indicated 92.21-89.57% between R.macroura vs. R. bicolour; 93.22-90% Ratufa macroura vs. Ratufa indica; 96-92% Ratufa indica vs. Ratufa bicolour, 93.88% between Ratufa affinis vs. Ratufa indica, 93.5% R. affinis vs. R. bicolor, 90.5%. R. affinis vs. R. macroura. Ratufa bicolor is noted to be genetically closer to R. indica as inferred by using both markers. The BLAST result indicated that the obtained sequences matched 99-100% with their respective species. It was also noted that R. bicolor of Jalpaiguri, West Bengal are genetically closer to that of Bhutan. The study also revealed the evolution of R. indica and R. macroura from a single population.

    In 1877, the major towns of the Straits Settlements-Singapore, George Town, Penang Island and Malacca-suffered a drought of exceptional magnitude. The drought's natural instigator was the El Niño phase of the El Niño Southern Oscillation, a climatic phenomenon then not understood by contemporary observers. The 1877 event has been explored in some depth for countries including India, China and Australia. Its impact on Southeast Asia however is less well-known and the story of how the event unfolded in Singapore and Malaysia has not been told. This paper explores how the contemporary British government responded to the drought, arguing that its impact on hydraulic management was at best minimal yet, it did have impact on other areas, such as forest reservation with the hope of preserving future rainfall. It also highlights how, in contrast to studies on urban water plans in other British Asian colonies, the colonial authorities in the Straits Settlements had a far less coherent and meaningful relationship with water in their town planning schemes. As this paper is part of a special issue, Water History in the time of COVID-19, it has undergone modified peer review.

    Background: The annual gross domestic expenditure on research and development (GERD) per capita of Indonesia ($24) remains relatively lower than the annual GERD per capita of neighboring countries, such as Vietnam ($36), Singapore ($1804), Malaysia ($361), and Thailand ($111).

    Objective: The aim of this study was to conduct a cost-effectiveness analysis of spending on healthcare R&D to address the needs of developing innovative therapeutic products in Indonesia.

    Methods: A decision tree model was developed by taking into account four stages of R&D: stage 1 from raw concept to feasibility, stage 2 from feasibility to development, stage 3 from development to early commercialization, and stage 4 from early to full commercialization. Considering a 3-year time horizon, a stage-dependent success rate was applied and analyses were conducted from a business perspective. Two scenarios were compared by assuming the government of Indonesia would increase GERD in health and medical sciences up to 2- and 3-times higher than the baseline (current situation) for the first and second scenario, respectively. Cost per number of innovative products in health and medical sciences was considered as the incremental cost-effectiveness ratio (ICER). Univariate sensitivity analysis was conducted to investigate the effects of different input parameters on the ICER.

    Results: There was a statistically significant association (P-value<0.05) between countries' GERD in medical and health sciences with the number of innovative products. We estimated the ICER would be $8.50 million and $2.04 million per innovative product for the first and second scenario, respectively. The sensitivity analysis showed that the success rates in all stages and total GERD were the most influential parameters impacting the ICER.

    Conclusion: The result showed that there was an association between GERD in medical and health sciences with the number of innovative products. In addition, the second scenario would be more cost-effective than the first scenario.

    Nipah virus (NiV) causes a severe and often fatal neurological disease in humans. Whilst fruit bats are considered the natural reservoir, NiV also infects pigs and may cause an unapparent or mild disease. Direct pig-to-human transmission was responsible for the first and still most devastating NiV outbreaks in Malaysia and Singapore in 1998-99, with nearly 300 human cases and over 100 fatalities. Pigs can therefore play a key role in the epidemiology of NiV by acting as an "amplifying" host. The outbreak in Singapore ended with the prohibition of pig imports from Malaysia and the Malaysian outbreak was ended by culling 45% of the country's pig population with costs exceeding US$500 million. Despite the importance of NiV as an emerging disease with the potential for pandemic, no vaccines, or therapeutics are currently approved for human or livestock use. In this mini-review, we will discuss current knowledge of NiV infection in pigs; our ongoing work to develop a NiV vaccine for use in pigs; and the pig as a model to support human vaccine development.

    Haemosporidians infect a wide diversity of bat genera and species, yet little is known about their transmission cycles or epidemiology. Though several recent studies have focused on the genus Hepatocystis, an Old World parasite primarily infecting bats, monkeys, and squirrels, this group is still understudied with little known about its transmission and molecular ecology. These parasites lack an asexual erythrocytic stage, making them unique from the Plasmodium vertebrate life cycle. In this study, we detected a prevalence of 31% of Hepatocystis in short-nosed fruit bats (Cynopterus brachyotis) in Singapore. Phylogenetic reconstruction with a partial cytochrome b sequence revealed a monophyletic group of Hepatocystis from C. brachyotis in Malaysia, Singapore, and Thailand. There was no relationship with infection and bat age, sex, location, body condition or monsoon season. The absence of this parasite in the five other bat species sampled in Singapore indicates this Hepatocystis species may be host restricted.

    In 2018, Kidney Disease: Improving Global Outcomes (KDIGO) published a clinical practice guideline on the prevention, diagnosis, evaluation, and treatment of hepatitis C virus (HCV) infection in chronic kidney disease (CKD). The guideline synthesized recent advances, especially in HCV therapeutics and diagnostics, and provided clinical recommendations and suggestions to aid healthcare providers and improve care for CKD patients with HCV. To gain insight into the extent that the 2018 guideline has been adopted in Asia, KDIGO convened an HCV Implementation Summit in Hong Kong. Participants included nephrologists, hepatologists, and nurse consultants from 8 Southeast Asian countries or regions with comparable high-to-middle economic ranking by the World Bank: mainland China, Hong Kong, Japan, Malaysia, Singapore, South Korea, Taiwan, and Thailand. Through presentations and discussions, meeting participants described regional practice patterns related to the KDIGO HCV in CKD guideline, identified barriers to implementing the guideline, and developed strategies for overcoming the barriers in Asia and around the world.

    Background/Aims: The efficacy and safety of vedolizumab in moderate to severely active ulcerative colitis (UC) have been demonstrated in the GEMINI 1 study (NCT00783718). This post-hoc exploratory analysis sought to establish the efficacy and safety of vedolizumab in a subgroup of patients from Asian countries with UC from GEMINI 1.

    Methods: Efficacy outcomes of interest were clinical response, clinical remission and mucosal healing at week 6 (induction phase); and clinical remission, durable clinical response, durable clinical remission, mucosal healing and glucocorticoid-free remission at week 52 (maintenance phase). Differences in outcome rates between vedolizumab and placebo in Asian countries (Hong Kong, India, Malaysia, Singapore, South Korea, and Taiwan) were assessed using descriptive analyses, and efficacy and safety compared between Asian and non-Asian countries.

    Results: During induction, in Asian countries (n = 58), clinical response rates at week 6 with vedolizumab and placebo were 55.2% and 24.1%, respectively (difference 31.0%; 95% confidence interval: 7.2%-54.9%). In non-Asian countries (n = 316), response rates at week 6 with vedolizumab and placebo were 45.9% and 25.8%, respectively. During maintenance, in Asian countries, clinical remission rates at 52 weeks with vedolizumab administered every 8 weeks, vedolizumab administered every 4 weeks and placebo were 9.1%, 36.8%, and 31.6%, respectively; corresponding rates for mucosal healing were 45.5%, 47.4%, and 47.4%, respectively. Vedolizumab was well-tolerated; adverse event frequency was comparable in Asian and non-Asian countries.

    Conclusions: In patients from Asian countries, the efficacy and safety of vedolizumab in treatment of UC were broadly consistent with that in the overall study population.

    Aedes-borne virus disease control relies on insecticides to interrupt transmission. Temephos remains a key chemical for control of immature stage Aedes in Thailand and much of Southeast Asia. However, repeated use of insecticides may result in selection for resistance in vector populations, thus compromising operational intervention. Herein, the phenotypic response to temephos by Aedes aegypti (L.) and Aedes albopictus (Skuse) collected in Thailand and surrounding countries is presented. Data from 345 collection sites are included: 283 from literature review (244 sites with Ae. aegypti, 21 with Ae. albopictus, and 18 having both species sampled), plus 62 locations with Ae. aegypti in Thailand conducted between 2014 and 2018. Susceptibility assays followed WHO guidelines using the recommended discriminating dose of temephos (0.012 mg/liter) against late third to early fourth instar Ae. aegypti. Findings revealed 34 locations with susceptible Ae. aegypti, 13 with suspected resistance, and 15 indicating resistance. Published data between 1999 and 2019 in Thailand found Ae. aegypti resistant in 73 of 206 collection sites, whereas 3 locations from 11 sampled with low-level resistant in Ae. albopictus. From surrounding countries conducting temephos assays (Cambodia, Lao PDR, Myanmar, Malaysia, and Singapore), resistance is present in Ae. aegypti and Ae. albopictus from 27 of 56 and 19 of 28 locations, respectively. Routine insecticide susceptibility monitoring should be an operational requirement in vector control programs. Given the wide distribution and apparent increase in temephos-resistance, alternative larvicidal compounds must be considered if chemical control is to remain a viable vector control strategy.

    While most countries in the Western Pacific Region (WPR) had similar trajectories of COVID-19 from January to May, their implementations of non-pharmaceutical interventions (NPIs) differed by transmission stages. To offer a better understanding for an implementation of multidisciplinary policies in COVID-19 control, we compared the impact of NPIs by assessing the transmissibility and severity of COVID-19 in different phases of the epidemic during the first five months in WPR. In this study, we estimated the piecewise instantaneous reproduction number (R
    t
    ) and the reporting delay-adjusted case-fatality ratio (dCFR) of COVID-19 in seven WPR jurisdictions: Hong Kong Special Administrative Region, Japan, Malaysia, Shanghai, Singapore, South Korea, and Taiwan. According to the results, implementing NPIs was associated with an apparent reduction of the piecewise R
    t
    in two epidemic waves in general. However, large cluster outbreaks raised the piecewise R
    t
    to a high level. We also observed relaxing the NPIs could result in an increase of R
    t
    . The estimated dCFR ranged from 0.09% to 1.59% among the jurisdictions, except in Japan where an estimate of 5.31% might be due to low testing efforts. To conclude, in conjunction with border control measures to reduce influx of imported cases which might cause local outbreaks, other NPIs including social distancing measures along with case finding by rapid tests are also necessary to prevent potential large cluster outbreaks and transmissions from undetected cases. A comparatively lower CFR may reflect the health system capacity of these jurisdictions. In order to keep track of sustained disease transmission due to resumption of economic activities, a close monitoring of disease transmissibility is recommended in the relaxation phase. The report of transmission of SARS CoV-2 to pets in Hong Kong and to mink in farm outbreaks highlight for the control of COVID-19 and emerging infectious disease, the One Health approach is critical in understanding and accounting for how human, animals and environment health are intricately connected.

    BACKGROUND: Borderline personality disorder (BPD) contributes to suicide-related morbidity and mortality and requires more intensive psychotherapeutic resources due to its high mental health service usage. Accessibility to an evidence-based treatment program is a cornerstone to support patients with BPD and part of broader suicide prevention efforts as well as improving their quality of life.

    AIMS: In this article, the authors aim to discuss and review available dialectical behavior therapy (DBT) and DBT-informed services of selected countries in the Asia-Pacific Rim, namely Singapore, Malaysia, and Mexico.

    MATERIALS & METHODS: We contacted providers of different services and gathered information on the process of setting up the service and adapting the treatment, in addition to reviewing the available literature published in the countries.

    RESULTS: To date, there have been a pair of DBT-informed services in Singapore, four in Malaysia, and several in Mexico with a few of them offering standard DBT. Different efforts have been put in place to increase the accessibility to training and also the number of DBT practitioners.

    DISCUSSION: Important considerations during the process of setting up new services include the use of domestic examples and local language that are contextually appropriate for the local community. Selected challenges faced in common include shortage of workforce, affordability of training programs, and the need for language adaptation with or without translation.

    CONCLUSION: Further long-term evaluation of locally adapted DBT-informed mental health services will help to elucidate the effectiveness and efficacy of the program which will potentially serve as a guide for other resource-scarce regions.
