Plumeria spp., native to tropical America, are popular small trees grown widely in tropical areas of the world and as potted plants elsewhere. P. rubra and P. obtusa cultivars and hybrids are most common. A rust disease of a Plumeria sp. (likely P. rubra based on pointed leaf tips, leaves more than 18 cm (7 inches) long, and high rust susceptibility) was observed in November 2008 and again in June 2009 on homeowner plants in Baton Rouge, LA. A survey of five Baton Rouge retail nurseries in September 2009 revealed that 87% (90 of 103) of the plumeria plants were heavily infected with rust. Early symptoms included numerous 1-mm chlorotic spots on adaxial leaf surfaces followed by leaf chlorosis, necrosis, and abscission. Uredinia were numerous, mostly hypophyllous and yellowish orange. Urediniospores were catenulate, orange en masse, verrucose, globose, ovoid, ellipsoidal or angular, and measured 21.8 to 41.9 × 16.4 to 32.8 μm (average 29.4 × 22.6 μm). The rust was identified as Coleosporium plumeriae Pat. (= C. plumierae) (3). Teliospores were not found during this study. Pathogenicity tests were performed by spraying urediniospores (20,000/ml of deionized water) on three healthy Thai hybrid plumeria plants. Five leaves of each plant were misted with water and covered with plastic bags and three to five leaves were inoculated. Plants were held at 27°C for 27 h in a dew chamber and then moved outdoors. Typical rust symptoms and uredinia with urediniospores developed in 10 days on all inoculated leaves while noninoculated leaves remained healthy. Characteristics and spore measurements matched those of the rust from original infected plants. Additional plumeria rust inoculations were made to other Apocynaceae family members that included Allamanda cathartica, Catheranthus roseus (Madagascar periwinkle), Mandevilla splendens, Nerium oleander, and Vinca major. Catheranthus roseus was very susceptible to C. plumeriae with chlorotic leaf spots developing on the six inoculated plants after 8 days and uredinia with urediniospores appearing after 11 days. None of the other plant genera were susceptible to the rust. Plumeria rust was also observed on plumeria trees in urban landscapes in peninsular (Penang) and Bornean (Kota Kinabalu, Sabah) Malaysia in December 2007. To confirm identity, ~1,000 bp of nuclear rDNA 28S subunit from each (Lousiana, Penang, and Kota Kinabalu) was sequenced with rust-specific primers (1) and shared 100% identity (GenBank No. GU145555-6). Plumeria rust was first found on the island of Guadeloupe (3) and then spread to Central and South America. It has been known from Florida since 1960 under the synonym C. domingense (2), but has not been reported elsewhere in the continental United States. In more recent years, plumeria rust has spread to Hawaii, many Pacific islands, India, China, Taiwan, Thailand, Australia, and Nigeria (4). To our knowledge, this is the first report of plumeria rust from Louisiana and Malaysia and of susceptibility of another member of the Apocynaceae, Madagascar periwinkle, to C. plumeriae.

The wolf spider genus Artoria Thorell, 1877 is a common group in Australasia, currently including 41 species from Australia, three from New Zealand and four from Pacific islands (Framenau Baehr 2018; Word Spider Catalog 2019). This does not, however, comprise the whole distribution of the genus. The type species, A. parvula Thorell, 1877 has been recorded from China, Philippines, Indonesia (Sulawesi) and Australia (Northern Territory). An endemic species, A. ligulacea (Qu, Peng Yin, 2009) was described from Yunnan, China. This indicates that there must be some undescribed species from Southeast Asian countries. A recent collecting expedition to Malaysia confirms this hypothesis. Two species of Artoria were found, the type species, A. parvula from East and West Malaysia and a new species, A. weiwei sp. nov. from East Malaysia. In this study, we illustrate the former and describe for the first time the latter species.
Accurate laboratory testing is a critical component of dengue surveillance and control. The objective of this programme was to assess dengue diagnostic proficiency among national-level public health laboratories in the World Health Organization (WHO) Western Pacific Region.
WHO's Declaration of the "Health for All" (HFA) goal was pronounced in 1978 in Alma Ata, and it was planned that HFA would be achieved through primary health care programmes and approaches by 2000. However, it is now 2002 and despite the technological advancements in medicine, science, and ICT, Health for All is far from reality. Instead, more and more conflicts are emerging with lethal consequences, such as, bioterrorism, biological agent abuse, global-terrorism, and environmental destruction is occurring at a greater scale that we have witnessed before. We may have the latest technology and knowledge today, but ironically, we are using them to inflict more suffering and pain in the world. In the Asia-Pacific, the past 30 years has seen dramatic advancement and lifestyle changes. We are now paying a high price for such progress in terms of risk factors to the health of the population, such as, ageing diseases, obesity, smoking, diabetes, hypertension, and related conditions. The social, political, economic and environmental factors appeared to have deterred and negated WHO's HFA goal to attain basic human rights and health care for all. The HFA will not be achieved in the future if we do not learn from history and start taking measures now.
The genetic diversity of 255 taro (Colocasia esculenta) accessions from Vietnam, Thailand, Malaysia,Indonesia, the Philippines, Papua New Guinea and Vanuatu was studied using AFLPs. Three AFLP primer combinations generated a total of 465 scorable amplification products. The 255 accessions were grouped according to their country of origin, to their ploidy level (diploid or triploid) and to their habitat--cultivated or wild. Gene diversity within these groups and the genetic distance between these groups were computed. Dendrograms were constructed using UPGMA cluster analysis. In each country, the gene diversity within the groups of wild genotypes was the highest compared to the diploid and triploid cultivars groups. The highest gene diversity was observed for the wild group from Thailand (0.19), the lowest for the diploid cultivars group from Thailand(0.007). In Malaysia there was hardly any difference between the gene diversity of the cultivars and wild groups, 0.07 and 0.08, respectively. The genetic distances between the diploid cultivars groups ranges from 0.02 to 0.10, with the distance between the diploid accessions from Thailand and Malaysia being the highest. The genetic distances between the wild groups range from 0.05 to 0.07. First, a dendrogram was constructed with only the diploids cultivars from all countries. The accessions formed clusters largely according to the country from which they originated. Two major groups of clusters were revealed, one group assembling accessions from Asian countries and the other assembling accessions from the Pacific. Surprisingly, the group of diploid cultivars from Thailand clustered among the Pacific countries. Secondly,a dendrogram was constructed with diploid cultivated,triploid cultivated and wild accessions. Again the division of the accessions into an Asian and a Pacific gene pool is obvious. The presence of two gene pools for cultivated diploid taro has major implications for the breeding and conservation of germplasm.
DNA samples were extracted from six prehistoric human remains, found on the Malay Peninsula, dating to the Paleolithic and the Neolithic periods. Nucleotide sequences of mitochondrial DNA were determined by the polymerase chain reaction-direct sequencing method. A phylogenetic tree between prehistoric and present humans was constructed based on the nucleotide sequence data. Mitochondrial DNA phylogenetic relationships and ethnoarchaeological evidence suggest that there is a continuity beetween the pre-Neolithic humans and the present Semang and that the Neolithic humans in this area might be an ancestral group of the Senoi.
The origins of linguistic diversity remain controversial. Studies disagree on whether group features such as population size or social structure accelerate or decelerate linguistic differentiation. While some analyses of between-group factors highlight the role of geographical isolation and reduced linguistic exchange in differentiation, others suggest that linguistic divergence is driven primarily by warfare among neighbouring groups and the use of language as marker of group identity. Here we provide the first integrated test of the effects of five historical sociodemographic and geographic variables on three measures of linguistic diversification among 50 Austronesian languages: rates of word gain, loss and overall lexical turnover. We control for their shared evolutionary histories through a time-calibrated phylogenetic sister-pairs approach. Results show that languages spoken in larger communities create new words at a faster pace. Within-group conflict promotes linguistic differentiation by increasing word loss, while warfare hinders linguistic differentiation by decreasing both rates of word gain and loss. Finally, we show that geographical isolation is a strong driver of lexical evolution mainly due to a considerable drift-driven acceleration in rates of word loss. We conclude that the motor of extreme linguistic diversity in Austronesia may have been the dispersal of populations across relatively isolated islands, favouring strong cultural ties amongst societies instead of warfare and cultural group marking.
Preoperative anaemia is common in the Asia-Pacific. Iron deficiency anaemia (IDA) is a risk factor that can be addressed under patient blood management (PBM) Pillar 1, leading to reduced morbidity and mortality. We examined PBM implementation under four different healthcare systems, identified challenges and proposed several measures: (a) Test for anaemia once patients are scheduled for surgery. (b) Inform patients about risks of preoperative anaemia and benefits of treatment. (c) Treat IDA and replenish iron stores before surgery, using intravenous iron when oral treatment is ineffective, not tolerated or when rapid iron replenishment is needed; transfusion should not be the default management. (d) Harness support from multiple medical disciplines and relevant bodies to promote PBM implementation. (e) Demonstrate better outcomes and cost savings from reduced mortality and morbidity. Although PBM implementation may seem complex and daunting, it is feasible to start small. Implementing PBM Pillar 1, particularly in preoperative patients, is a sensible first step regardless of the healthcare setting.
Good nutrition in the first "1000 days," including breastfeeding and appropriate complementary foods, prepares for a healthy childhood and adult life, also contributes to the prevention of the double burden of malnutrition. Exclusive breastfeeding provides all required nutrients until an infant is around 6 months of age when complementary foods are needed. A literature review was undertaken of complementary foods in the Asia Pacific region. The foods being used at present are often of low nutrient density may provide insufficient amounts of some critical nutrients, and generally the variety is limited. Guidelines for complementary feeding are provided to assist in education and in public health planning.
INTRODUCTION: Many low and middle-income countries rely on out-of-pocket payments to help finance health care. These payments can pose financial hardships for households; valid measurement of this type of economic burden is therefore critical. This study examines the validity of five survey measures of economic burden caused by health care payments.
METHODS: We analyzed 2002/03 World Health Survey household-level data from four Asia Pacific countries to assess the construct validity of five measures of economic burden due to health care payments: any health expenditure, health expenditure amount, catastrophic health expenditure, indebtedness, and impoverishment. We used generalized linear models to assess the correlations between these measures and other constructs with which they have expected associations, such as health care need, wealth, and risk protection.
RESULTS: Measures of impoverishment and indebtedness most often correlated with health care need, wealth, and risk protection as expected. Having any health expenditure, a large health expenditure, or even a catastrophic health expenditure did not consistently predict degree of economic burden.
CONCLUSIONS: Studies that examine economic burden attributable to health care payments should include measures of impoverishment and indebtedness.

Although health technology assessment (HTA) has been well established in all developed countries, it has not found a firm footing in many developing countries. This is especially true of the Asia Pacific region, which has much of the world population.
BACKGROUND AND OBJECTIVE: The Asthma Insight and Management (AIM) survey was conducted in North America, Europe, the Asia-Pacific region and Latin America to characterize patients' insights, attitudes and perceptions about their asthma and its treatment. We report findings from the Asia-Pacific survey.
METHODS: Asthma patients (≥12 years) from Australia, China, Hong Kong, India, Malaysia, Singapore, South Korea, Taiwan and Thailand were surveyed. Patients answered 53 questions exploring general health, diagnosis/history, symptoms, exacerbations, patient burden, disease management, medications/treatments and patient's attitudes. The Global Initiative for Asthma guidelines were used to assess asthma control. The survey was conducted by random digit telephone dialling (Australia, China and Hong Kong) or by random face-to-face interviews (India, Malaysia, Singapore, South Korea, Taiwan and Thailand).
RESULTS: There were 80 761 households screened. Data from 3630 patients were collected. Wide disparity existed between objective measures of control and patient perception. Reported exacerbations during the previous year ranged from 19% (Hong Kong) to 67% (India). Reported unscheduled urgent/emergency visits to a doctor's office/hospital/clinic in the previous year ranged from 15% (Hong Kong) to 46% (Taiwan). Patients who reported having controlled asthma in the previous month ranged from 27% (South Korea) to 84% (Taiwan). Substantial functional and emotional limitations due to asthma were identified by 13% (South Korea) to 78% (India) of patients.
CONCLUSIONS: Asthma has a profound impact on patients' well-being despite the availability of effective treatments and evidence-based management guidelines. Substantial differences across the surveyed countries exist, suggesting unmet, country-specific cultural and educational needs. A large proportion of asthma patients overestimate their level of control.
Study site: random digit telephone dialling or by random face-to-face interviews at pre-selected locations.
Island health differs from other health care systems, particularly in that there are limited resources and referral faculties available. With globalisation and climate change, island populations have become increasingly vulnerable to natural disasters and global pandemics. This study will identify, explore, compare and report on island health issues facing in the western Pacific, before making appropriate recommendations. A review of selected health indicators in Pacific islands was collected from the World Health Organization (WHO) and other publicly available resources. In the Pacific region, 15 islands saw lower health expenditure (
The World Health Organization (WHO) selected antimicrobial resistance (AMR) as the theme for World Health Day 2011. The slogan was "Combat Drug Resistance - No action today, no cure tomorrow" A six-point policy package was launched as a core product for World Health Day. It aimed to stimulate extensive and coherent action to overcome the many challenges presented by antimicrobial resistance.
"This paper assesses the level and composition of contemporary Asian immigration to Australia and explores its processes and impacts. The final reversal of the White Australia Policy in the 1970s opened the door to substantial increases in Asian immigration, particularly from Vietnam, Malaysia, the Philippines, China, India and Hong Kong." Aspects considered include migrant categories, age, sex, and social and economic adaptation to Australia.
Inshore marine resources play an important role in the livelihoods of Pacific Island coastal communities. However, such reliance can be detrimental to inshore marine ecosystems. Understanding the livelihoods of coastal communities is important for devising relevant and effective fisheries management strategies. Semi-structured household interviews were conducted with householders in Langalanga Lagoon, Solomon Islands, to understand household livelihoods and resource governance in fishing-dependent communities. Households were engaged in a diverse range of livelihoods. Fishing, shell money production and gardening were the most important livelihoods. Proximity to an urban centre influenced how households accessed some livelihoods. Perceptions of management rules varied and different reasons were cited for why rules were broken, the most common reason being to meet livelihood needs. Current models of inshore small-scale fisheries management that are based on the notion of community-based resource management may not work in locations where customary management systems are weak and livelihoods are heavily reliant on marine resources. An important step for fisheries management in such locations should include elucidating community priorities through participatory development planning, taking into consideration livelihoods as well as governance and development aspirations.
