    Introduction:Alternative treatment for cancer from herbal medicine has gained interest due to its benefits on im-mune modulation, improving the survival and quality of life. Mitragyna speciosa (M. speciosa) or Kratom is an indig-enous plant that can be found in Thailand and northern part of Peninsular Malaysia has becomes popular in recent years due to its ability to exhibit the opioid-like effects of analgesia. Mitragynine is the main alkaloid in M. speciosa which is found to reduce gastrointestinal motility and has been used by local communities as traditional treatment for diarrhoea and many other diseases. However, there is lack of scientific evidence to show that M. speciosa has anti-oxidative and anti-cancer properties especially in colorectal cancer. Therefore, our study aims to evaluate the anti-oxidative properties of M. Speciosa methanolic extract (MSME) and its effects on colorectal cancer cell line, SW480. Methods: The anti-oxidant content and scavenging activity of MSME were determined by total phenolic content (TPC) assay and total flavonoid content (TFC) assay as well as 2,2’-azino-bis (3-ethylbenzothiazoline-6-sul-phonic acid) (ABTS) assay and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay respectively. Cytotoxicity and cytokine inhibitory effects of MSME on SW480 cells were determined by (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxy-phenyl)-2-(4-sulfophenyl)-2H-tetrazolium) (MTS) and cytokine beads array (CBA), respectively. Results: The TPC of MSME (0.1mg/ml = 85.85 ± 8.25 mg GAE/g extract; 1mg/ml = 167.43 ± 13.50 mg GAE/g extract; 10mg/ml = 408.94 ±7.17 mg GAE/g extract) was lower than pterostilbene, the positive control drug (76.37 ± 2.75; 230.52 ± 10.92; 835.44 ± 6.84 mg GAE/g extract). Conversely, the TFC of MSME (0.1mg/ml = 32.17 ± 27.92 mg QE/g extract; 1mg/ml = 347.72 ± 15.97 mg QE /g extract; 10mg/ml = 739.81 ± 5.56 mg QE /g extract) was slightly higher than pteros-tilbene (ND; 212.73 ± 17.92; 700.50 ± 3.47 mg QE/g extract). In DPPH assay, MSME showed comparatively similar antioxidant scavenging activity (IC50=4.34μg/ml) with pterostilbene (IC50=4.393μg/ml). However, MSME showed lower anti-oxidant scavenging activity (IC50=4.26μg/ml) than pterostilbene (IC50=1.556μg/ml) as measured by ABTS assay. In cytotoxicity assay, IC50 of MSME on SW480 cells was determined to be at 1.486 mg/ml. Overexpression of cytokines such as IL-6, IL-8 (CXCR8) and IL-10 could potentially promote tumour cell proliferation, growth and metastasis. Increased production of these cytokines through LPS stimulation in SW480 was slightly reduced by treat-ment with MSME. Conclusion: MSME could have a potential bioactive compound that possesses anti-oxidative and anti-cancer properties that would be beneficial as an alternative treatment of colorectal cancer.

    Suwantika AA, Kautsar AP, Zakiyah N, Abdulah R, Boersma C, Postma MJ
    Ther Clin Risk Manag, 2020;16:969-977.
    PMID: 33116546 DOI: 10.2147/TCRM.S260377
    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.

    PMID: 32457710 DOI: 10.3389/fmicb.2020.00778
    Melioidosis is a common infectious disease in Southeast Asia and Northern Australia. In Hainan, several cases have been reported, but no systematic study has yet been done on the molecular epidemiology profiles of the organism. An investigation of the molecular epidemiology links and population structure of Burkholderia pseudomallei would help to better understand the clonally of the isolates and differences among them. In this study, multilocus variable-number tandem repeat analysis (MLVA), and multilocus sequence typing (MLST) were applied to examine the epidemiological relatedness and population structure of 166 B. pseudomallei isolates obtained during 2002-2014 in Hainan, China. Both the MLVA_4 and MLST approaches had high discriminatory power for this population, with diversity indices of 0.9899 and 0.9457, respectively. However, the MLVA_4 assay showed a higher discriminatory power than the MLST approach, and a variable-number tandem repeat (VNTR3 933) found by the MLVA approach was the most useful in discriminating strains from this province. A total of 166 strains yielded 99 MLVA_4 genotypes, of which 34 genotypes were shared by 101 isolates, for a clustering rate of 60.8% (101/166), which suggested that some cases may have a common source. Additionally, 65 isolates showed distinct genotypes, indicating that more than 39.2% (65/166) of melioidosis cases in Hainan had epidemiologically unrelated or sporadic characteristics. The 166 isolates were resolved into 48 STs, of which five STs (ST55, -70, -46, -50, and -58) were here found to be predominant. Phylogenetic analysis of 116 isolates conducted using the eBURST v3 segregated the 48 STs into eight groups with ST50 as predicted founder, and 21 STs were found to be singletons, which suggest that the strains in the Hainan region represent a high diversity of ST clones, indicating that many B. pseudomallei clone groups are endemic to this region. Moreover, ST50 had 5 SLV, 7 DLV, 6 TLV, and 29 satellite STs and formed a radial expansion pattern, suggesting that the melioidosis epidemic in this study was mainly caused by the clonal expansion of ST 50. Phylogenetic analysis on global scale suggests that China's isolates are closely related to isolates from Southeast Asia, particularly from Thailand and Malaysia.

  4. Fulltext Ecology of bat flies in Singapore: A study on the diversity, infestation bias and host specificity (Diptera: Nycteribiidae)
    Lim ZX, Hitch AT, Lee BPY, Low DHW, Neves ES, Borthwick SA, et al.
    Int J Parasitol Parasites Wildl, 2020 Aug;12:29-33.
    PMID: 32420022 DOI: 10.1016/j.ijppaw.2020.04.010
    Bat flies are highly-specialized, hematophagous arthropods that are globally ubiquitous. There is little published research on bat flies (Diptera: Nycteribiidae) in Singapore and understanding the diversity of nycteribiids, host association and infestation rates can provide insight into this host-ectoparasite relationship. Nycteribiids were collected from bats trapped in Singapore (2011-2016) and identified using morphological keys. Host-ectoparasite relationships were investigated with logistic regression and Bayesian poisson regression. Nycteribiids were found to be monoxenously associated with their host bat species and host age, sex, species, and BBCI appear to contribute to differences in prevalence and intensity. Differences in host specificity between bat fly species in Singapore and their conspecifics in less disturbed habitats with higher bat biodiversity, such as Malaysia, Philippines and Thailand, suggest that the high host specificity in Singapore derives from the paucity of suitable hosts and abundance of single species roosts and not from their coevolved restrictions to them.

  5. Revisiting the pollution haven hypothesis in ASEAN-5 countries: new insights from panel data analysis
    Guzel AE, Okumus İ
    Environ Sci Pollut Res Int, 2020 May;27(15):18157-18167.
    PMID: 32172423 DOI: 10.1007/s11356-020-08317-y
    Pollution haven hypothesis (PHH) has been investigated extensively in the existing literature due to global environmental issues such as global warming and climate change. However, there is still no consensus on whether this hypothesis is valid. Therefore, the aim of this study is to examine the validity of the PHH in ASEAN-5 countries (Indonesia, Malaysia, Philippines, Singapore, and Thailand) covering the period of 1981-2014. It is utilized the up-to-date panel data techniques taking cross-sectional dependence and slope heterogeneity into account to test the relationship. According to the results of CCEMG and AMG estimators, the validity of the PHH is confirmed in ASEAN-5 countries. The increase in foreign direct investments (FDI) increases environmental degradation in these countries. Our additional findings show that the environmental Kuznets curve (EKC) hypothesis (EKC) is also valid in these countries. There is an inverted U shape between economic growth and CO2 emissions. In addition, energy consumption exacerbates CO2 emissions.

  6. Fulltext Dataset on the influence of relative humidity on the pathogenicity of Metarhizium anisopliae isolates from Thailand and Malaysia against red palm weevil (Rhynchophorus ferrugineus, Olivier) adult
    Cheong JL, Azmi WA
    Data Brief, 2020 Jun;30:105482.
    PMID: 32368576 DOI: 10.1016/j.dib.2020.105482
    Red palm weevil (RPW), Rhynchophorus ferrugineus, is a polyphagous insect that caused economic damage in various palm species, particularly coconut plantation in Malaysia. Therefore, entomopathogenic fungus Metarhizium anisopliae was being introduced in attempts to control biologically the RPW. The entomopathogenicity of an indigenous (Met-Gra4) and foreign (Met-TH) strains of M. anisopliae isolated from the soil of Malaysia and Thailand, were tested against RPW adults in laboratory bioassays at 50, 70, 90% relative humidity (RH). Bioassays indicate no significance differences in efficacy between both the conidia of M. anisopliae strains against RPW adults. Met-Gra4 showed the highest efficacy at 90% RH (LT50 = 6.17 days). However, LT50 only slightly differed from Met-TH (6.33 days; 90% RH). Scanning el ectron microscopy for the treated RPWs showed that Met-Gra4 (90% RH) was densely sporulated within the abdomen, while Met-TH can be found mainly across cuticular surface of RPW.

    Liu YH, Huang WH
    Front Public Health, 2020;8:32.
    PMID: 32154204 DOI: 10.3389/fpubh.2020.00032
    This study investigates the asymmetric effects of business cycles (measured by real GDP per capita) on population health (measured by life expectancy at birth) from the ASEAN countries, namely, Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, and Vietnam. The panel vector error correction model, together with various panel unit root tests and cointegration tests, suggested a hidden cointegrated relationship between life expectancy at birth and the positive and negative components of real GDP per capita, and the asymmetric effects of business cycles on population health were identified in both in the short run and in the long run. Policymakers should focus on the harmful effects of business cycles on population health, and government interventions should be more forceful in times of economic expansion than during periods of economic recession.

  8. Fulltext Two multinational, observational surveys investigating perceptions of beauty and attitudes and experiences relating to aesthetic medical procedures
    Redaelli A, Siddiqui Syed S, Liu X, Poliziani M, Erbil H, Prygova I, et al.
    J Cosmet Dermatol, 2020 Nov;19(11):3020-3031.
    PMID: 32153099 DOI: 10.1111/jocd.13349
    BACKGROUND: Data on opinions and experiences of aesthetic medical procedures outside the United States and Western Europe are scarce.

    AIMS: This study aimed to survey users and non-users of aesthetic procedures in countries where this information is less readily available, to understand attitudes and perceptions relating to beauty.

    PATIENTS/METHODS: Two independent internet-based observational surveys were conducted. Survey 1: individuals from Colombia, Lebanon, Malaysia, Russia and Turkey who were 'users' or 'non-users' of aesthetic medical procedures. Survey 2: individuals from Colombia, Russia, Thailand, Turkey and the United Arab Emirates who were 'users' of non-surgical aesthetic treatments.

    RESULTS: Surveys 1 and 2 were completed by 300 and 160 individuals, respectively, most of whom were female (94.0% and 99%). Overall, respondents rated the eyes and smile as the most pleasing male and female facial features. Most participants (mean 82.6%; range 75%-100%) believed maintaining a healthy lifestyle was important for ageing gracefully, and over one-third (36.0%; 28%-47%) believed men age more gracefully than women. The emphasis respondents placed on the importance of physical attributes vs inner feelings, internal beauty and self-confidence varied between countries. Users were often more positive about aesthetic medical procedure outcomes than non-users. Adequate information, good physician communication (including managing treatment expectations), treatment recommendations based on patient need and good aftercare improved treatment satisfaction.

    CONCLUSIONS: The eyes and smile were key features of attractiveness, but maintaining a healthy lifestyle was consistently considered an important factor for ageing gracefully. Ensuring patients are well informed was a major determinant of treatment satisfaction.

  9. Susceptibility of Aedes aegypti and Aedes albopictus (Diptera: Culicidae) to Temephos in Thailand and Surrounding Countries
    Saeung M, Ngoen-Klan R, Thanispong K, Muenworn V, Bangs MJ, Chareonviriyaphap T
    J Med Entomol, 2020 07 04;57(4):1207-1220.
    PMID: 32159772 DOI: 10.1093/jme/tjaa035
    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.

  10. Fulltext Identification, prevalence and pathogenicity of Colletotrichum species causing anthracnose of Capsicum annuum in Asia
    de Silva DD, Groenewald JZ, Crous PW, Ades PK, Nasruddin A, Mongkolporn O, et al.
    IMA Fungus, 2019;10:8.
    PMID: 32355609 DOI: 10.1186/s43008-019-0001-y
    Anthracnose of chili (Capsicum spp.) causes major production losses throughout Asia where chili plants are grown. A total of 260 Colletotrichum isolates, associated with necrotic lesions of chili leaves and fruit were collected from chili producing areas of Indonesia, Malaysia, Sri Lanka, Thailand and Taiwan. Colletotrichum truncatum was the most commonly isolated species from infected chili fruit and was readily identified by its falcate spores and abundant setae in the necrotic lesions. The other isolates consisted of straight conidia (cylindrical and fusiform) which were difficult to differentiate to species based on morphological characters. Taxonomic analysis of these straight conidia isolates based on multi-gene phylogenetic analyses (ITS, gapdh, chs-1, act, tub2, his3, ApMat, gs) revealed a further seven known Colletotrichum species, C. endophyticum, C. fructicola, C. karsti, C. plurivorum, C. scovillei, C. siamense and C. tropicale. In addition, three novel species are also described as C. javanense, C. makassarense and C. tainanense, associated with anthracnose of chili fruit in West Java (Indonesia); Makassar, South Sulawesi (Indonesia); and Tainan (Taiwan), respectively. Colletotrichum siamense is reported for the first time causing anthracnose of Capsicum annuum in Indonesia and Sri Lanka. This is also the first report of C. fructicola causing anthracnose of chili in Taiwan and Thailand and C. plurivorum in Malaysia and Thailand. Of the species with straight conidia, C. scovillei (acutatum complex), was the most prevalent throughout the surveyed countries, except for Sri Lanka from where this species was not isolated. Colletotrichum siamense (gloeosporioides complex) was also common in Indonesia, Sri Lanka and Thailand. Pathogenicity tests on chili fruit showed that C. javanense and C. scovillei were highly aggressive, especially when inoculated on non-wounded fruit, compared to all other species. The existence of new, highly aggressive exotic species, such as C. javanense, poses a biosecurity risk to production in countries which do not have adequate quarantine regulations to restrict the entry of exotic pathogens.

    PMID: 32490095 DOI: 10.1016/j.dib.2020.105746
    Short tandem repeat (STR) loci are widely used as genetic marker for ancestral and forensic analyses. The latter application includes for paternity testing and DNA profiling of samples collected from scenes of crime and suspects. This survey provides the first dataset for 21 STR loci across the Akan population in Ghana by genotyping of 109 unrelated healthy individuals using Investigator 24plex kit. None of the STR loci screened deviated from Hardy-Weinberg equilibrium after applying Bonferroni correction. Overall, 224 unique alleles were observed with allele frequencies ranging from 0.005 to 0.518. The combined match probability, combined power of exclusion and combined power discrimination were 1 in 4.07 × 10-25, 0.999999999 and 1, respectively. Principal coordinate analysis carried out using 21 STR allele frequency data mapped the Akans with Nigerian subpopulation groups (Hausa, Igbo and Yoruba), but separated from Thais of Thailand, Chechen of Jordan and Tijuana of Mexico.

    Aupalee K, Saeung A, Srisuka W, Fukuda M, Streit A, Takaoka H
    Pathogens, 2020 Jun 25;9(6).
    PMID: 32630410 DOI: 10.3390/pathogens9060512
    The transmission of zoonotic filarial parasites by black flies has so far been reported in the Chiang Mai and Tak provinces, Thailand, and the bites of these infected black flies can cause a rare disease-human zoonotic onchocerciasis. However, species identification of the filarial parasites and their black fly vectors in the Chiang Mai province were previously only based on a morphotaxonomic analysis. In this study, a combined approach of morphotaxonomic and molecular analyses (mitochondrial cox1, 12S rRNA, and nuclear 18S rRNA (SSU HVR-I) genes) was used to clarify the natural filarial infections in female black flies collected by using human and swine baits from two study areas (Ban Lek and Ban Pang Dang) in the Chiang Mai province from March 2018 to January 2019. A total of 805 and 4597 adult females, belonging to seven and nine black fly taxa, were collected from Ban Lek and Ban Pang Dang, respectively. At Ban Lek, four of the 309 adult females of Simulium nigrogilvum were positive for Onchocerca species type I in the hot and rainy seasons. At Ban Pang Dang, five unknown filarial larvae (belonging to the same new species) were detected in Simulium sp. in the S. varicorne species-group and in three species in the S. asakoae species-group in all seasons, and three non-filarial larvae of three different taxa were also found in three females of the S. asakoae species-group. This study is the first to molecularly identify new filarial species and their vector black fly species in Thailand.

  14. Fulltext Examining the asymmetric effects of fiscal policy instruments on environmental quality in Asian economies
    Ullah S, Majeed MT, Chishti MZ
    Environ Sci Pollut Res Int, 2020 Oct;27(30):38287-38299.
    PMID: 32623670 DOI: 10.1007/s11356-020-09859-x
    Empirical studies pertaining to the effects of fiscal policy instruments on environmental quality have provided mixed evidence. We consider the asymmetric effects of fiscal policy instruments on environmental quality for the top ten Asian carbon emitters over the period 1981-2018. We go beyond the literature and claim that the effects could be asymmetric. More specifically, we found that a positive shock in government expenditure will worsen environmental quality in Malaysia, UAE, Thailand, Indonesia, Turkey, Iran, India, and China, and improve it in Japan. On the other hand, we found that cutting government expenditure will improve environmental quality in these economies and will worsen only in Japan. Moreover, a higher government income tax revenue uniquely increases the government's spending that increases the carbon emissions in Malaysia, UAE, Thailand, Indonesia, Turkey, Iran, India, and China, and decrease in Japan. The negative shock of government revenue has adverse results on carbon emissions in these economies. However, short-run asymmetric effects translate to long-run effects in most Asian economies.

  15. Alcohol consumption and attributable harm in middle-income South-East Asian countries: Epidemiology and policy options
    Sornpaisarn B, Shield K, Manthey J, Limmade Y, Low WY, Van Thang V, et al.
    Int J Drug Policy, 2020 Jul 22;83:102856.
    PMID: 32711336 DOI: 10.1016/j.drugpo.2020.102856
    Background Factors and policies which potentially explain the changes in alcohol consumption and related harms from 2010 to 2017 in 11 middle-income countries in the South-East Asian region (Cambodia, Lao PDR, Indonesia, the Philippines, Malaysia, Maldives, Myanmar, Sri Lanka, Thailand, Timor-Leste, and Vietnam) were examined. Methods Using secondary data from UN agencies, we analyzed trends in alcohol consumption, alcohol-attributable deaths and the burden of disease. Results Starting from a level of consumption significantly below the global average-especially among the Muslim-majority countries (Maldives, Indonesia, and Malaysia)-the majority of the countries in this region had markedly increased their alcohol consumption along with the economic development they experienced between 2010 and 2017. In fact, five middle-income countries in this region (Vietnam, Lao PDR, Cambodia, Myanmar, and Timor-Leste) were in the top 12 countries globally based on absolute increases in adult alcohol per capita consumption (APC). The Philippines and Malaysia were the exceptions, as they had reduced their APC over this period. The majority of South-East Asian countries had parallel increasing trends in the age-standardized alcohol-attributable deaths and DALYs since 2010, in contrast to global trends. While all countries put some alcohol control policies in place, there were differences in the number and strength of the policies applied, commensurate with trends in consumption. In particular, three of the countries which were most successful in reducing consumption and harm (Malaysia, Philippines, and Sri Lanka) applied more effective tax methods based on specific taxation alone or in combination with another taxation method, applying higher taxation rates and regularly increasing them over time. Conclusion To achieve the global target and the Sustainable Development Goal in reducing alcohol consumption worldwide, middle-income countries, especially lower-middle-income countries, should employ stricter alcohol control policies, and apply an appropriate excise tax on alcohol products with regular increases to reflect inflation.

    Erythroxylum cuneatum (E. cuneatum) which belongs to Erythroxylaceae family is a tropical flowering plant from the genus of Erythroxylum. It is used in Malaysia and Thailand's traditional medicines, yet there is limited scientific reports on its medicinal value. This study aimed at exploring the antioxidative and anti-inflammatory properties of E. cuneatum alkaloid leaf extract. The alkaloid extract was obtained through Soxhlet heat extraction method, while the antioxidantive properties were assessed via 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, ferric reducing antioxidant power (FRAP) and xanthine oxidase inhibition (XOI) assays. Further, anti-inflammatory property of the extract was evaluated on rat's model of carrageenan induced paw model of edema via physical measurements and histology. The extract exhibited antioxidant activity with an EC50 value of 1482 μg/ml in the DPPH radical scavenging assay, an EC1 value of 2191 μg/ml in the FRAP assay and 10.15 ± 6.20% in the XOI assay. Rats pretreated with the extract have shown dose dependent decrease in paw edema when compared to non-treated group of rats. The highest dose (50 mg/kg) of extract exhibited similar effects to aspirin in terms of reducing paw thickness, leucocytes infiltration and disruption of collagen. In conclusion, the E. cuneatum alkaloid leaf extract possesses both antioxidative and anti-inflammatory properties suggesting its potentials for future development of antioxidant and anti-inflammatory drugs.

    Three new species of black flies from Thailand, Simulium wangkwaiense, S. tadtonense and S. maeklongkeense, are described based on their adults, pupal exuviae and cocoons. All three new species are assigned to the Simulium (Simulium) striatum species-group, bringing its total number in Thailand to seven. Simulium wangkwaiense sp. nov. is the species formerly called S. quinquestriatum in Thailand. Certain male and pupal morphological characteristics are shown to separate all seven Thai species of this species-group. All of the three new species have been analyzed genetically for their phylogenetic relationships, with three known related species (except for S. thailandicum), by using the fast-evolving nuclear big zinc finger (BZF) gene.

    Primary health care is essential for equitable, cost-effective and sustainable health care. It is the cornerstone to achieving universal health coverage against a backdrop of rising health expenditure and aging populations. Implementing strong primary health care requires grassroots understanding of health system performance. Comparing successes and barriers between countries may help identify mutual challenges and possible solutions. This paper compares and analyses primary health care policy in Australia, Malaysia, Mongolia, Myanmar, Thailand and Vietnam. Data were collected at the World Organization of National Colleges, Academies and Academic Associations of General Practitioners/Family Physicians (WONCA) Asia-Pacific regional conference in November 2017 using a predetermined framework. The six countries varied in maturity of their primary health care systems, including the extent to which family doctors contribute to care delivery. Challenges included an insufficient trained and competent workforce, particularly in rural and remote communities, and deficits in coordination within primary health care, as well as between primary and secondary care. Asia-Pacific regional policy needs to: (1) focus on better collaboration between public and private sectors; (2) take a structured approach to information sharing by bridging gaps in technology, health literacy and interprofessional working; (3) build systems that can evaluate and improve quality of care; and (4) promote community-based, high-quality training programs.

    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.

    Malaria parasites in the phylum Apicomplexa (Order: Haemosporida) infect diverse vertebrates and invertebrate hosts. At least seven genera of haemosporidian parasites have been described to exclusively infect bats. Most of these parasites remain enigmatic with a poorly known host range. Here, we investigated 271 bats belonging to 21 species and seven families from six provinces of Thailand. Overall, 124 out of 271 bats (45.8%) were positive for haemosporidian parasites, while none had Plasmodium, based on microscopic examination of blood smears and PCR amplification. We obtained 19 distinct cytochrome b (cytb) nucleotide haplotypes of Hepatocystis from seven bat species (families: Craseonycteridae, Hipposideridae, Pteropodidae, and Rhinolophidae). Nycteria was found in four bat species (Craseonycteridae, Emballonuridae, Megadermatidae, and Pteropodidae) and Polychromophilus in two species (Emballonuridae, Vespertilionidae). Phylogenetic analysis inferred from cytb sequences placed Hepatocystis into 2 different clades. Most Hepatocystis infections were found in insectivorous bats and clustered together with a sequence from Hipposideros larvatus in Cambodia (in subclade 1a). A single sequence of Hepatocystis obtained from a frugivorous bat, Cynopterus brachyotis, was placed in the same clade with Hepatocystis from the same bat species previously reported in Malaysia (clade 2). Nycteria in these Thai bats were clearly separated from the African isolates previously reported in bats in the family Rhinolophidae. Polychromophilus murinus from Myotis siligorensis was placed in a distinct clade (clade 2) from Polychromophilus melanipherus isolated from Taphozous melanopogon (clade 1). These results confirmed that at least two distinct species of Polychromophilus are found in Thailand. Collectively, Hepatocystis presented no host specificity. Although Megaderma spasma seemed to be infected by only Nycteria, its respective parasite does not show specificity to only a single bat host. Polychromophilus murinus and P. melanipherus seem to infect a narrower host range or are somehow restricted to bats in the families Vespertilionidae and Emballonuridae, respectively.
