    Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are toxic compounds derived from anthropogenic sources that stay in the environment for long periods. Ambient air has become the most important pathway for the transfer of PCDDs/PCDFs from emission sources to the environment. This review intends to summarise the information available on atmospheric PCDDs/PCDFs in the countries of Southeast Asia to provide a detailed description of the trends in PCDDs/PCDFs emissions, key sources, and levels in urban, rural, and industrial air as reported in peer-reviewed literature since 2000 and by the United Nations Environment Programme. As the largest country in Southeast Asia, Indonesia is the major PCDDs/PCDFs emitter, accounting for 72.81% of the total release of PCDDs/PCDFs in the air from all available inventories in this region, while Brunei Darussalam is the lowest emitter, contributing to less than 0.02%. Open burning processes have become the largest source of ambient PCDDs/PCDFs in the region (69.62%), followed by waste incineration (10.69%), and ferrous and non-ferrous metal production (8.78%). PCDDs/PCDFs levels in rural areas ranged between 10 and 38 fg TEQ m-3; however, where open burning waste has occurred, the levels rose to 12-29 times higher. In urban areas, ambient levels were 15 times greater than in rural areas, varying from 23 to 565 fg TEQ m-3. Atmospheric concentrations near industrial palm oil and waste incinerator sites were between 64 and 1530 fg TEQ m-3. The non-cancer risk of ambient exposure to PCDDs/PCDFs through inhalation is low among populations near facilities emitting PCDDs/PCDFs. The lack of local technical capacity, the high economic costs, and the lack of established human resource capacities have been the major challenges in conducting ambient PCDDs/PCDFs studies in most countries in the region.

    Yun TC, Ahmad SR, Quee DKS
    Malays J Med Sci, 2018 May;25(3):56-66.
    PMID: 30899187 DOI: 10.21315/mjms2018.25.3.6
    Background: Young adults are at risk of developing obesity, especially when transitioning into university life as they become responsible for their daily eating and lifestyles. This study estimates the prevalence of overweight/obesity and explores the eating patterns and lifestyle practices of university students.

    Methods: A cross-sectional study was conducted at Universiti Brunei Darussalam (UBD). A total of 303 students participated. Data was collected from January to April 2016. Self-designed questionnaires comprised questions pertaining to current weight, self-reported height data, information on eating habits, exercise and knowledge of the food pyramid. The collected data were used to compare and contrast eating habits and lifestyle practices among overweight/obese students with those of non-overweight/obese students.

    Results: The prevalence of overweight/obesity was 28.8% (95% CI: 24.0%, 34.0%). The majority ate regular daily meals, but more than half skipped breakfast. Frequent snacking, fried food consumption at least three times per week and low intake of daily fruits and vegetables were common. The frequency of visits to fast food restaurants was significantly higher in the overweight/obese. 25.4% of the students exercised at least three times per week. Almost all students are aware of balanced nutrition and the food pyramid.

    Conclusions: Most university students had poor eating habits, although the majority had good nutrition knowledge. By way of recommendation, the university is encouraged to provide a multi-disciplinary team specialising in health promotion that includes nutrition and physical activity programmes to increase the awareness among the university students.

    Win KN, Trivedi A, Lai AS
    Ind Health, 2018 Nov 21;56(6):566-571.
    PMID: 29973468 DOI: 10.2486/indhealth.2018-0053
    In 2012, there were about 2.3 million deaths worldwide attributed to work. The highest workplace fatality rate (WFR) was reported on construction sites due to high risk activities. Globally, fall from height is the leading cause of fatal injuries for construction workers. The objectives are to determine Brunei Darussalam's demographic distribution of occupational fatality; identify causal agents and industry where occupational fatalities commonly occur; and determine WFR by year. This cross-sectional study retrospectively reviewed records of occupational fatality which were notified to the Occupational Health Division, Ministry of Health, from January 2012 until December 2016. Notified occupational fatalities in Brunei over a five-year period was 50. Most of the cases were in 31-40 age group. 38% of fatality cases occurred in Indonesian workers. 60% were from the Construction industry. 38% were due to fall from height. WFR averaged 5.28 and the highest industry-specific fatality rate was seen in the Construction industry, ranging from 27.94 to 56.45 per 100,000 workers. WFR for Brunei Darussalam from 2012 to 2016 was similar to that of Malaysia, but higher than Singapore and the UK. Industry-specific fatality rate for the Construction and Manufacturing industries were higher than those of Singapore and the UK.

  8. Phylogenetic position of Aerumnosa Mohrig (Diptera, Sciaridae) as revealed by multigene analysis, with the description of four new Oriental species
    Vilkamaa P, Rudzinski HG, BurdÍkovÁ N, ŠevČÍk J
    Zootaxa, 2018 Mar 21;4399(2):248-260.
    PMID: 29690308 DOI: 10.11646/zootaxa.4399.2.8
    Four Oriental species of Aerumnosa Mohrig, 1999 (Diptera: Sciaridae), a genus previously known only from Papua New Guinea, are newly described and illustrated: Aerumnosa bituberculata sp. n. (India), A. gemmifera sp. n. (Malaysia: Sabah), A. horrifica sp. n. (Brunei, Thailand) and A. impar sp. n. (Malaysia: Sabah). On the basis of the new material, the genus is redefined. A key to the known species of Aerumnosa is presented, including four new species. An updated molecular phylogenetic analysis based on four gene markers (18S, 28S, 16S and COI) shows Aerumnosa to be a member of the subfamily Cratyninae. The monophyly of Cratyninae is well supported, which clade also includes the genera Hyperlasion Schmitz, 1919, Pnyxiopalpus Vilkamaa Hippa, 1999 and Pseudoaerumnosa Rudzinski, 2006. According to the present phylogenetic hypothesis, the monophyly of Cratyna Winnertz, 1967 s. l. needs to be revisited. The clade including Cratyna (s. str.) ambigua (Lengersdorf, 1934) appears as the sister group of Aerumnosa.

  12. The genus Ranatra Fabricius (Heteroptera: Nepidae) in Borneo, with a redescription of Ranatra spinifrons Montandon and the description of a new species
    Tran AD, Poggi R
    Zootaxa, 2019 Feb 12;4555(2):236-246.
    PMID: 30790959 DOI: 10.11646/zootaxa.4555.2.4
    The type of Ranatra spinifrons Montandon, 1910 is redescribed and this taxon is reported from Brunei for the first time. Ranatra heoki sp.n. is described from Sarawak and belongs to the Ranatra gracilis group (sensu Lansbury, 1972). The present paper also provides the first records of the following species for Borneo: Ranatra parmata Mayr, 1865 (from Sabah and Kalimantan); Ranatra rafflesi Tran Polhemus, 2012 (from Sarawak). The latter is also reported from Sumatra for the first time. Ranatra longipes longipes Stål, 1861, previously known from Kalimantan and Sabah, is now reported from Sarawak for the first time. Thus, six species of Ranatra are currently known from Borneo.

  13. Fulltext Prognostic indicators of management of sudden sensorineural hearing loss in an Asian hospital
    Tiong TS
    Singapore Med J, 2007 Jan;48(1):45-9.
    PMID: 17245516
    INTRODUCTION: This retrospective review evaluates the prognostic indicators in the management of sudden sensorineural hearing loss (SSNHL) in otorhinolaryngology patients admitted to Brunei RIPAS Hospital.
    METHODS: The review covered data collected from 1996 to 1998, and included patients who were treated with naftidrofuryl and dexamethasone. Their hearing improvement (more than 20 dB) in relation to pure tone audiogram patterns, hearing loss severity, vertigo, age of the patients and duration from symptom onset to time of treatment, were evaluated.
    RESULTS: After exclusion of three patients with known causes of hearing loss, 50 patients with idiopathic SSNHL were reviewed. Six audiogram patterns were observed with good prognostic indicators in patterns 1 and 4, where respectively, 95 percent and 100 percent of the patients improved. The hearing improvement was noted in the majority of the patients with mild or moderate degree of hearing loss, especially noticeable in audiogram patterns 1 and 4. Initial vertigo gave poor prognosis in hearing (more than 33 percent patients with vertigo improved versus 88 percent patients without vertigo improved). Patients aged between 21 and 60 years appear to have better prognosis of hearing improvement compared to those who are outside of this age range. 92 percent patients whose treatment started within the first week of onset of hearing loss experienced hearing improvement compared to 84 percent patients whose treatment started in the second week after onset.
    CONCLUSION: Fairly consistent with the previously-reported prognostic indicators are hearing loss severity, vertigo, age and duration of onset to treatment, though there was reasonably good prognosis when the patients were treated in the second week from hearing loss onset. Further findings of note were the six audiogram patterns and the good prognostic indicators in patterns 1 and 4.

  14. Use of sterols and linear alkylbenzenes as molecular markers of sewage pollution in Southeast Asia
    Thomes MW, Vaezzadeh V, Zakaria MP, Bong CW
    Environ Sci Pollut Res Int, 2019 Nov;26(31):31555-31580.

    Southeast Asia has undergone rapid developments in terms of urbanization, economic and population growth. The progress in sewerage treatment infrastructure has not kept pace with such developments. The inadequacy and inefficiency of sewerage systems has prompted the release of untreated sewage into the aquatic environment of Southeast Asia causing many waterborne illnesses since surface water is utilized for recreational, agricultural and aquaculture purposes and, above all, as a source of water intake in Southeast Asia. This paper will review the current data on molecular markers of sewage pollution including sterols and linear alkylbenzenes (LABs) in Southeast Asian aquatic environment to clarify the state of sewage pollution and the competence of sewage treatment plants (STPs) in this area. Despite the importance of sewage pollution research in the region, the number of studies using molecular markers to trace the sources of sewage pollution is limited. So far, indicators of sewage pollution have been investigated in aquatic environments of Indonesia, Vietnam, Malaysia, the Philippines, Thailand, Cambodia and Brunei among Southeast Asian countries. The concentrations and diagnostic ratios of faecal sterols and LABs show the release of untreated and primary treated urban waste into water bodies of these countries. Further studies are required to fill the data gaps in Southeast Asia and come to a better understanding of the trends of sewage pollution in this part of the world. Graphical abstract.

    J Invertebr Pathol, 2015 Sep;130:37-41.

    A microsporidian parasite, Enterocytozoon hepatopenaei (abbreviated as EHP), is an emerging pathogen for penaeid shrimp. EHP has been found in several shrimp farming countries in Asia including Vietnam, Thailand, Malaysia, Indonesia and China, and is reported to be associated with growth retardation in farmed shrimp. We examined the histological features from infected shrimp collected from Vietnam and Brunei, these include the presence of basophilic inclusions in the hepatopancreas tubule epithelial cells, in which EHP is found at various developmental stages, ranging from plasmodia to mature spores. By a PCR targeting the 18S rRNA gene, a 1.1kb 18S rRNA gene fragment of EHP was amplified, and this sequence showed a 100% identity to EHP found in Thailand and China. This fragment was cloned and labeled with digoxigenin-11-dUTP, and in situ hybridized to tissue sections of infected Penaeus vannamei (from Vietnam) and P. stylirostris (Brunei). The results of in situ hybridization were specific, the probe only reacted to the EHP within the cytoplasmic inclusions, not to a Pleistophora-like microsporidium that is associated with cotton shrimp disease. Subsequently, we developed a PCR assay from this 18S rRNA gene region, this PCR is shown to be specific to EHP, did not react to 2 other parasitic pathogens, an amoeba and the cotton shrimp disease microsporidium, nor to genomic DNA of various crustaceans including polychaetes, squids, crabs and krill. EHP was detected, through PCR, in hepatopancreatic tissue, feces and water sampled from infected shrimp tanks, and in some samples of Artemia biomass.

  16. Tsunami run-up and inundation along the coast of Sabah and Sarawak, Malaysia due to a potential Brunei submarine mass failure
    Tan WK, Teh SY, Koh HL
    Environ Sci Pollut Res Int, 2017 Jul;24(19):15976-15994.
    PMID: 28343360 DOI: 10.1007/s11356-017-8698-x
    Submarine landslides, also known as submarine mass failures (SMFs), are major natural marine disasters that could critically damage coastal facilities such as nuclear power plants and oil and gas platforms. It is therefore essential to investigate submarine landslides for potential tsunami hazard assessment. Three-dimensional seismic data from offshore Brunei have revealed a giant seabed mass deposited by a previous SMF. The submarine mass extends over 120 km from the continental slope of the Baram Canyon at 200 m water depth to the deep basin floor of the Northwest Borneo Trough. A suite of in-house two-dimensional depth-averaged tsunami simulation model TUNA (Tsunami-tracking Utilities and Application) is developed to assess the vulnerability of coastal communities in Sabah and Sarawak subject to potential SMF tsunami. The submarine slide is modeled as a rigid body moving along a planar slope with the center of mass motion parallel to the planar slope and subject to external forces due to added mass, gravity, and dissipation. The nonlinear shallow water equations are utilized to simulate tsunami propagation from deepwater up to the shallow offshore areas. A wetting-drying algorithm is used when a tsunami wave reaches the shoreline to compute run up of tsunami along the shoreline. Run-up wave height and inundation maps are provided for seven densely populated locations in Sabah and Sarawak to highlight potential risks at each location, subject to two scenarios of slide slopes: 2° and 4°. The first wave may arrive at Kudat as early as 0.4 h after the SMF, giving local communities little time to evacuate. Over a small area, maximum inundated depths reaching 20.3 m at Kudat, 26.1 m at Kota Kinabalu, and 15.5 m at Miri are projected, while the maximum inundation distance of 4.86 km is expected at Miri due to its low-lying coast. In view of the vulnerability of some locations to the SMF tsunami, it is important to develop and implement community resilience program to reduce the potential damage that could be inflicted by SMF tsunamis.

    There are now more than 28,000 described orthopterans globally (Cigliano et al., 2018) and this figure is likely to increase in the future. The same is true for Southeast Asia, where we are still at a stage of discovering species new to science, and this is partly an artefact of incomplete sampling (Tan et al., 2017a). In one of the most popular biodiversity hotspots, i.e., Borneo, is the Kuala Belalong Field Studies Centre. It is located in the primary lowland and ridge dipterocarp forests of the Ulu Temburong National Park, Brunei Darussalam. Recent collection of orthopterans in the area led to the discovery of several new species of katydids (Tan et al., 2017b; Tan Wahab, 2017a) and crickets (Tan et al., 2017c; Tan Wahab, 2017b). Here, we describe another new species of katydid, from the genus Tapiena Bolívar, 1906. Tapiena currently consists of 26 species (Tan et al., 2015) and is distributed around Asia and even Africa. In Borneo, only one species is known: Tapiena incisa Karny, 1923 from Sarawak (see Karny, 1923). The new species Tapiena paraincisa sp. nov. represents the second species described from Borneo.
