The lack of relationship between acetylator phenotype and idiopathic systemic lupus erythematosus in a South-east Asian population: a study of Indians, Malays and Malaysian Chinese

Ong ML, Mant TG, Veerapen K, Fitzgerald D, Wang F, Manivasagar M, et al.

Br J Rheumatol, 1990 Dec;29(6):462-4.
PMID: 2257457

An association of idiopathic systemic lupus erythematosus (ISLE) with genetically determined N-acetylation polymorphism has been suspected from previous studies, mainly on Caucasian populations in which there is an approximate incidence of 50% of slow and rapid acetylators. The present study is of the incidence of ISLE and acetylator status in a mixed population of Malaysia. The results did not support an association between ISLE and acetylator status: the frequencies of slow acetylators in the ISLE patients who were Malaysian Chinese and Malay were 13 and 38% respectively. This did not differ significantly from the respective healthy groups (20 and 29%). The small number of Indians in the survey did not allow a valid comparison, but the figures did suggest a lack of association between ISLE and acetylator status.

Clinical stage of chronic granulocytic leukaemia and BCR breakpoint location in South-East Asian patients

Dyck JA, Bosco JJ

Br J Haematol, 1989 May;72(1):64-7.
PMID: 2736243

Forty-six Malaysian patients with chronic granulocytic leukaemia were found to be rearranged in the breakpoint cluster region (BCR) of chromosome 22, molecular evidence of Philadelphia chromosome (t9.22) translocation. Through the use of a 1.2 kb 3' BCR probe and two restriction enzyme digests, patients' breakpoints could be localized either to 5' or 3' regions of the BCR. Breakpoint site localization at the time of DNA sampling did not show any positive statistical association to clinical status defined as chronic phase, chronic phase with less than 6 months to blast crisis, accelerated phase and blast crisis. This was in contrast to earlier reports which indicated that patients with breakpoint at 3' site were at a higher biologic risk for entering blast crisis.

Child health, breast-feeding, and survival in Malaysia: a random-effects logit approach

Montgomery MR, Richards T, Braun HI

J Am Stat Assoc, 1986 Jun;81(394):297-309.
PMID: 12155406

This study examines the possibility that estimation of the effect of breast-feeding on infant survival is affected by selection bias, in that children who are healthier at birth may be more likely to be breast-fed. Data are from the 1976 Malaysian Family Life Survey. "Ordinary logit models for breast-feeding and survival are estimated, and the results suggest that selection is indeed present. For example, children of higher birth weight appear to be more likely to be breast-fed and likely to survive. In addition, weight at birth and the duration of breast-feeding appear to be linked." Using birth weight as an indicator for the child's health, the authors conclude that "the direct influence of breast-feeding on survival remains of overwhelming importance even after corrections for selection bias are made."

Fulltext Genome of a middle Holocene hunter-gatherer from Wallacea

Carlhoff S, Duli A, Nägele K, Nur M, Skov L, Sumantri I, et al.

Nature, 2021 Aug;596(7873):543-547.
PMID: 34433944 DOI: 10.1038/s41586-021-03823-6

Much remains unknown about the population history of early modern humans in southeast Asia, where the archaeological record is sparse and the tropical climate is inimical to the preservation of ancient human DNA1. So far, only two low-coverage pre-Neolithic human genomes have been sequenced from this region. Both are from mainland Hòabìnhian hunter-gatherer sites: Pha Faen in Laos, dated to 7939-7751 calibrated years before present (yr cal BP; present taken as AD 1950), and Gua Cha in Malaysia (4.4-4.2 kyr cal BP)1. Here we report, to our knowledge, the first ancient human genome from Wallacea, the oceanic island zone between the Sunda Shelf (comprising mainland southeast Asia and the continental islands of western Indonesia) and Pleistocene Sahul (Australia-New Guinea). We extracted DNA from the petrous bone of a young female hunter-gatherer buried 7.3-7.2 kyr cal BP at the limestone cave of Leang Panninge2 in South Sulawesi, Indonesia. Genetic analyses show that this pre-Neolithic forager, who is associated with the 'Toalean' technocomplex3,4, shares most genetic drift and morphological similarities with present-day Papuan and Indigenous Australian groups, yet represents a previously unknown divergent human lineage that branched off around the time of the split between these populations approximately 37,000 years ago5. We also describe Denisovan and deep Asian-related ancestries in the Leang Panninge genome, and infer their large-scale displacement from the region today.

Fulltext Investigating cultural evolution using phylogenetic analysis: the origins and descent of the southeast Asian tradition of warp ikat weaving

Buckley CD

PLoS One, 2012;7(12):e52064.
PMID: 23272211 DOI: 10.1371/journal.pone.0052064

The warp ikat method of making decorated textiles is one of the most geographically widespread in southeast Asia, being used by Austronesian peoples in Indonesia, Malaysia and the Philippines, and Daic peoples on the Asian mainland. In this study a dataset consisting of the decorative characters of 36 of these warp ikat weaving traditions is investigated using Bayesian and Neighbornet techniques, and the results are used to construct a phylogenetic tree and taxonomy for warp ikat weaving in southeast Asia. The results and analysis show that these diverse traditions have a common ancestor amongst neolithic cultures the Asian mainland, and parallels exist between the patterns of textile weaving descent and linguistic phylogeny for the Austronesian group. Ancestral state analysis is used to reconstruct some of the features of the ancestral weaving tradition. The widely held theory that weaving motifs originated in the late Bronze Age Dong-Son culture is shown to be inconsistent with the data.

Male circumcision and penis enhancement in Southeast Asia: matters of pain and pleasure

Hull TH, Budiharsana M

Reprod Health Matters, 2001 Nov;9(18):60-7.
PMID: 11765401

This paper reviews some uniquely male sexual health concerns in Southeast Asia, with particular attention to Indonesia. These include various forms of male circumcision, different types of 'penis enhancement' carried out across the region and the use of dry sex by women. These practices appear to be motivated by specific notions of sexual pleasure, based on indigenous gender constructs. Although they may or may not pose a serious public health problem, as markers of misguided or exploitative gender relations they do reveal important aspects of social psychology related to sexuality and sexual health. Male circumcision provides an ideal opportunity to consider male reproductive health needs and risks in Indonesia, Malaysia and the Philippines. Practices that involve cutting the male genitals need to be addressed in ways that stress the importance of sexual relationships based on mutual respect and open communication. Penis implants and inserts and other penis augmentation devices, as well as dry sex practices, are potentially dangerous to both men and women, and of questionable value in bringing pleasure to either, and should be discouraged.

Spatiotemporal analysis of ground and satellite-based aerosol for air quality assessment in the Southeast Asia region

Nguyen TTN, Pham HV, Lasko K, Bui MT, Laffly D, Jourdan A, et al.

Environ Pollut, 2019 Dec;255(Pt 1):113106.
PMID: 31541826 DOI: 10.1016/j.envpol.2019.113106

Satellite observations for regional air quality assessment rely on comprehensive spatial coverage, and daily monitoring with reliable, cloud-free data quality. We investigated spatiotemporal variation and data quality of two global satellite Aerosol Optical Depth (AOD) products derived from MODIS and VIIRS imagery. AOD is considered an essential atmospheric parameter strongly related to ground Particulate Matter (PM) in Southeast Asia (SEA). We analyze seasonal variation, urban/rural area influence, and biomass burning effects on atmospheric pollution. Validation indicated a strong relationship between AERONET ground AOD and both MODIS AOD (R2 = 0.81) and VIIRS AOD (R2 = 0.68). The monthly variation of satellite AOD and AERONET AOD reflects two seasonal trends of air quality separately for mainland countries including Myanmar, Laos, Cambodia, Thailand, Vietnam, and Taiwan, Hong Kong, and for maritime countries consisting of Indonesia, Philippines, Malaysia, Brunei, Singapore, and Timor Leste. The mainland SEA has a pattern of monthly AOD variation in which AODs peak in March/April, decreasing during wet season from May-September, and increasing to the second peak in October. However, in maritime SEA, AOD concentration peaks in October. The three countries with the highest annual satellite AODs are Singapore, Hong Kong, and Vietnam. High urban population proportions in Singapore (40.7%) and Hong Kong (21.6%) were associated with high AOD concentrations as expected. AOD values in SEA urban areas were a factor of 1.4 higher than in rural areas, with respective averages of 0.477 and 0.336. The AOD values varied proportionately to the frequency of biomass burning in which both active fires and AOD peak in March/April and September/October. Peak AOD in September/October in some countries could be related to pollutant transport of Indonesia forest fires. This study analyzed satellite aerosol product quality in relation to AERONET in SEA countries and highlighted framework of air quality assessment over a large, complicated region.

Craniodental affinities of Southeast Asia's "negritos" and the concordance with their genetic affinities

Bulbeck D

Hum Biol, 2013 Feb-Jun;85(1-3):95-133.
PMID: 24297222

Genetic research into Southeast Asia's "negritos" has revealed their deep-rooted ancestry, with time depth comparable to that of Southwest Pacific populations. This finding is often interpreted as evidence that negritos, in contrast to other Southeast Asians, can trace much of their ancestry directly back to the early dispersal of Homo sapiens in the order of 70 kya from Africa to Pleistocene New Guinea and Australia. One view on negritos is to lump them and Southwest Pacific peoples into an "Australoid" race whose geographic distribution had included Southeast Asia prior to the Neolithic incursion of "Mongoloid" farmers. Studies into Semang osteology have revealed some hints of Southwest Pacific affinities in cranial shape, dental morphology, and dental metrical "shape." On the other hand, the Andamanese have been shown to resemble Africans in their craniometrics and South Asians in their dental morphology, while Philippine negritos resemble Mongoloid Southeast Asians in these respects and also in their dental metrics. This study expands the scope of negrito cranial comparisons by including Melayu Malays and additional coverage of South Asians. It highlights the distinction between the Mongoloid-like Philippine negritos and the Andamanese and Semang (and Senoi of Malaya) with their non-Mongoloid associations. It proposes that the early/mid-Holocene dispersal of the B4a1a mitochondrial DNA clade across Borneo, the Philippines, and Taiwan may be important for understanding the distinction between Philippine and other negritos.

Fulltext Sequence and Phylogenetic Analysis of the First Complete Genome of Ricetungro spherical virus in Malaysia

Kannan M, Mohamad Saad M, Zainal Z, Kassim H, Ismail I, Talip N, et al.

Iran J Biotechnol, 2020 Oct;18(4):e2566.
PMID: 34056024 DOI: 10.30498/IJB.2020.2566

Background: Rice tungro disease (RTD) is a viral disease mainly affecting rice in Asia. RTD caused by Rice tungro bacilliform virus and Rice tungro spherical virus. To date, there are only 5 RTSV isolates have been reported.
Objectives: In this study, we aimed to report the complete nucleotide sequence of Malaysian isolate of Rice tungro spherical virus Seberang Perai (RTSV-SP) for the first time. RTSV-SP was characterized and its evolutionary relationship with previously reported Indian and Philippines isolates were elucidated.
Materials and Methods: RTSV-SP isolate was isolated from a recent outbreak in a paddy field in Seberang Perai zone of Malaysia. Its complete genome was amplified by RT-PCR, cloned and sequenced.
Results: Sequence analysis indicated that the genome of RTSV-SP consisted of 12,173 nucleotides (nt). Comparative analysis of 6 complete genome sequences using Clustal Omega showed that Seberang Perai isolate shared the highest nucleotide identity (96.04%) with Philippine-A isolate, except that the sORF-2 of RTSV-SP is shorter than RTSV Philippine-A by 27 amino acid residues. RTSV-SP found to cluster in Southeast Asia (SEA) group based on the whole genome sequence phylogenetic analysis using MEGA X software.
Conclusions: Phylogenetic classification of RTSV isolates based on the complete nucleotide sequences showed more distinctive clustering pattern with the addition of RTSV-SP whole genome to the available isolates. Present study described the isolation and molecular characterization of RTSV-SP.

PMID: 26211106

Occupational safety and health is one of important issues for workforce movement among ASEAN countries. The objective was to study laws, main agencies, and law enforcement regarding occupational safety and health in Thailand, Indonesia, Malaysia, Philippines, and Singapore. This documentary research covered laws, main agencies' duties, and occupational safety and health law enforcement in Thailand, Indonesia, Malaysia, Philippines, and Singapore. Thailand has its Occupational Safety, Health, and Work EnvironmentAct 2011. Its main agency was Department of Labor Protection and Welfare. Indonesia had WorkSafety Act (Law No. 1, 1970). Its main agency was Department of Manpower and Transmigration. Malaysia had Occupational Safety and Health Act (OSHA) 1994. Its main agency is the Department of Occupational Safety and Health. The Philippines has its Occupational Safety and Health Standards. Its main agency was Department ofLabor and Employment. Singapore has its Workplace Safety and Health Act 2006. Its main agency is Occupational Safety and Health Division. Occupational safety and health law enforcement among each county covers work environment surveillance, workers' health surveillance, advice about prevention and control of occupational health hazards, training and education of employers and employees, data systems, and research. Further in-depth surveys of occupational safety and health among each ASEAN county are needed to develop frameworks for occupational safety and health management for all ASEAN countries.

Age at marriage in Malaysia: a hazard model of marriage timing

Anderson KH, Hill MA, Butler JS

J Dev Econ, 1987 Aug;26(2):223-34.
PMID: 12280709

"This paper estimates a proportional hazards model for the timing of age at marriage of women in Malaysia. We hypothesize that age at marriage responds significantly to differences in male and female occupations, race, and age. We find considerable empirical support for the relevance of economic variables in determining age at marriage as well as evidence of strong differences in marriage patterns across races."

Fulltext Recommended dietary allowances harmonization in Southeast Asia

Barba CV, Cabrera MI

Asia Pac J Clin Nutr, 2008;17 Suppl 2:405-8.
PMID: 18460439

Issues and opportunities for RDA harmonization within the SEA region were first raised during the First Regional Forum and Workshop "RDAs: Scientific Basis and Future Directions", held in Singapore in March 1997. A regional review on RDAs in SEA showed general similarities for the different RDAs, although in some cases a country listed an exceptionally high or low RDA for a particular nutrient for a specific group. It also revealed differences in physiologic groupings and reference body weights, nutrients included and units of expression. Realizing these differences in RDA components between countries which makes technical composition different, a consensus on the need for regional collaboration and harmonization of RDAs was reached by participants from Indonesia, Malaysia, Philippines, Singapore, Thailand and Vietnam. A follow-up workshop was organized to work towards agreement throughout the region on common approaches, concepts and terminologies; application and uses, format and a research agenda. Round table discussions were held to arrive at specific recommendations for achieving harmonization. While divergence in opinions were expected, some clear-cut agreements were settled. Globalization envisions to achieve economic growth and development, with the effects expected to ripple through health, nutrition and welfare improvements. The harmonization of RDAs in SEA seeks to reach this vision by strengthening R and D capabilities (both logistic and manpower) within the region and within the countries in the region, as well as harmonizing the efforts of governments and industry within the region to reduce potential trade barriers such as those relating to food and nutrition quality assurance standards.

Conservation focus: the challenge of conservation in changing tropical southeast asia

Lynam AJ, Porter L, Campos-Arceiz A

Conserv Biol, 2016 10;30(5):931-932.
PMID: 27341391 DOI: 10.1111/cobi.12781

Southeast Asia is a biodiversity hotspot where the risk of extinction for many vertebrates is high (Duckworth et al. 2012) due to the loss and degradation of habitats resulting from burgeoning human populations and economies, expansion of agricultural development, and unsustainable harvest of wildlife and other natural resources (Sodhi et al. 2010). Important conservation challenges in the region, especially in the terrestrial and coastal realms, include reducing the loss and degradation of native vegetation and reducing the risk of species' extinction and extirpation. This will involve mitigating impacts of land-use change, reducing human-wildlife conflicts, improving management of protected areas, resolving land-tenure conflicts, increasing community engagement in in resource conservation, and ultimately developing proconservation behaviors in Asian societies as a whole.

Fulltext Recommendations for the optimal care of patients with recent-onset psychosis in the Asia-Pacific region

Lo TL, Warden M, He Y, Si T, Kalyanasundaram S, Thirunavukarasu M, et al.

Asia Pac Psychiatry, 2016 Jun;8(2):154-71.
PMID: 27062665 DOI: 10.1111/appy.12234

Providing optimal care to patients with recent-onset psychosis can improve outcomes and reduce relapse. However, there is a lack of consistency of the implementation of guidelines for such patients across the Asia-Pacific region. We determined a pragmatic set of recommendations for use on a day-to-day basis to help provide optimal care at this crucial stage of illness. The recommendations were developed over a series of meetings by an international faculty of 15 experts from the Asia-Pacific region, Europe, and South Africa. A structured search of the PubMed database was conducted. This was further developed based on the faculty's clinical experience and knowledge of the literature into 10 key aspects of optimal care for patients during the first five years of a diagnosis of a psychotic disorder, with particular relevance to the Asia-Pacific region. Several common principles emerged: adherence to antipsychotic medications is crucial; substance abuse, psychiatric and medical comorbidities should be addressed; psychosocial interventions play a pivotal role; and family members can play a vital role in overall patient care. By following these recommendations, clinicians may improve outcomes for patients with recent-onset psychosis.

Using reference nutrient density goals with food balance sheet data to identify likely micronutrient deficits for fortification planning in countries in the Western Pacific region

Gibson RS, Cavalli-Sforza T

Food Nutr Bull, 2012 Sep;33(3 Suppl):S214-20.
PMID: 23193773

Collection of nationwide food consumption data at the individual level is the preferred option for planning fortification programs. However, such data are seldom collected in low-income countries. In contrast, Food Balance Sheets (FBS), published annually for approximately 180 countries, may provide a source of national data for program planning.

Population diversity of Diaphorina citri (Hemiptera: Liviidae) in China based on whole mitochondrial genome sequences

Wu F, Jiang H, Beattie GAC, Holford P, Chen J, Wallis CM, et al.

Pest Manag Sci, 2018 Nov;74(11):2569-2577.
PMID: 29688605 DOI: 10.1002/ps.5044

BACKGROUND: Diaphorina citri (Asian citrus psyllid; ACP) transmits 'Candidatus Liberibacter asiaticus' associated with citrus Huanglongbing (HLB). ACP has been reported in 11 provinces/regions in China, yet its population diversity remains unclear. In this study, we evaluated ACP population diversity in China using representative whole mitochondrial genome (mitogenome) sequences. Additional mitogenome sequences outside China were also acquired and evaluated.
RESULTS: The sizes of the 27 ACP mitogenome sequences ranged from 14 986 to 15 030 bp. Along with three previously published mitogenome sequences, the 30 sequences formed three major mitochondrial groups (MGs): MG1, present in southwestern China and occurring at elevations above 1000 m; MG2, present in southeastern China and Southeast Asia (Cambodia, Indonesia, Malaysia, and Vietnam) and occurring at elevations below 180 m; and MG3, present in the USA and Pakistan. Single nucleotide polymorphisms in five genes (cox2, atp8, nad3, nad1 and rrnL) contributed mostly in the ACP diversity. Among these genes, rrnL had the most variation.
CONCLUSION: Mitogenome sequences analyses revealed two major phylogenetic groups of ACP present in China as well as a possible unique group present currently in Pakistan and the USA. The information could have significant implications for current ACP control and HLB management. © 2018 Society of Chemical Industry.

Progress toward poliomyelitis eradication -- Western Pacific Region, January 1, 1996-September 27, 1997

Centers for Disease Control and Prevention (CDC)

MMWR Morb Mortal Wkly Rep, 1997 Nov 28;46(47):1113-7.
PMID: 9393657

In 1988, the World Health Assembly adopted the goal of global poliomyelitis eradication by 2000, which was endorsed in each of the six regions of the World Health Organization (WHO). In the Western Pacific Region (WPR), where the last known case of polio associated with isolation of wild poliovirus occurred in March 1997, the reported number of cases decreased from 5963 in 1990 to 197 in 1996. This report documents progress toward polio eradication in WPR from January 1, 1996, through September 27, 1997, in countries where polio is endemic (Cambodia, China, Laos, Papua New Guinea, Philippines, and Vietnam) or recently was endemic (Malaysia and Mongolia) and describes the routine and supplemental vaccination activities necessary to interrupt wild poliovirus transmission in the region.
