A new species of small, insular, forest floor skink, Sphenomorphus perhentianensis sp. nov., is described from Pulau Perhentian Besar of the Perhentian Archipelago, Peninsular Malaysia. This species is differentiated from all other 36 Sundaland species of Sphenomorphus based on a unique collection of morphological and colour pattern characteristics. These unique characteristics include a snout-vent length of 30.0 mm, 29 midbody scale rows, smooth as opposed to striated dorsal scales, 65 paravertebrals, 61 ventrals, 4 supraoculars, parietals contacting the posterior-most supraocular, 1 medially projecting superciliary scale, 2 loreals, 6 supralabials and infralabials, 10 lamellae beneath the fourth toe, smooth subdigital lamellae, enlarged preanal scales, no body bands, a dark brown, diffuse, dorsolateral stripe extending to just past the axilla, a cream coloured dorsolateral stripe on the nape and anterior-most portion of the body, and no cream coloured postorbital stripe. The discovery of a second endemic reptile in the Perhentian Archipelago underscores the unrealized biodiversity of its herpetofauna. Additional works will describe two additional species from the Perhentian Archipelago.

Trop Life Sci Res, 2018 Mar;29(1):87-101.
PMID: 29644017 MyJurnal DOI: 10.21315/tlsr2018.29.1.6

Red seaweed Gracilaria, one of the largest genus in Division Rhodophyta inhabits Sarawak coastal water. This study was designed to identify the species of Gracilaria using morphological approach and to assess selected water quality parameters in Gracilaria habitats. Three field samplings were carried out in Santubong and Asajaya, Sarawak from November 2013 to December 2014. Overall, three species were identified namely Gracilaria changii, G. blodgettii and G. coronopifolia, attached to net of cage culture in Santubong and root of mangrove trees in Asajaya. In addition, three different taxa of aquatic macroinvertebrates (polychaete, small crab, bivalve) and single species of red seaweed (Acanthophora sp.) were observed in Gracilaria assemblages. An estimate of 37% to 40% of the upper part of the cage net in Santubong was covered by seaweeds and only 16% to 20% in Asajaya's mangrove. The study had provided better information on identification of Gracilaria and their habitat in Sarawak. Future work involving DNA barcoding of each species is in progress.

Zainordin 'F, Ab Hamid S

Trop Life Sci Res, 2017 Jul;28(2):9-29.
PMID: 28890758 MyJurnal DOI: 10.21315/tlsr2017.28.2.2

Stable isotope analysis has been used extensively to establish trophic relationships in many ecosystems. Present study utilised stable isotope signatures of carbon and nitrogen to identify trophic structure of aquatic food web in river and rice field ecosystems in Perak, northern peninsular Malaysia. The mean δ(13)C values of all producers ranged from -35.29 ± 0.21 to -26.00 ± 0.050‰. The greatest δ(15)N values noted was in zenarchopterid fish with 9.68 ± 0.020‰. The δ(15)N values of aquatic insects ranged between 2.59 ± 0.107 in Elmidae (Coleoptera) and 8.11 ± 0.022‰ in Nepidae (Hemiptera). Correspondingly, with all the δ(13)C and δ(15)N values recorded, it can be deduced that there are four trophic levels existed in the freshwater ecosystems which started with the producer (plants), followed by primary consumer (aquatic insects and non-predatory fish), secondary consumer (invertebrate predators) and lastly tertiary consumer (vertebrate predators).

MyJurnal

Like many other countries, reservoirs in Malaysia are primarily built for various
functions such as hydroelectric power generation, drinking water supply, flood mitigation
and irrigation for agricultural purposes. Artisanal fisheries activities were also performed in
these reservoirs. The freshwater fish are a requisite source of protein for the rural
population. Consequently, the fish resources in reservoirs should be carefully maintained
at sustainable level. Present study elucidates the preliminary assessment on autecological
studies of beardless barb, Cyclocheilichthys apogon as a model of fish biota in Muda
Reservoir. This research investigates the growth pattern of C. apogon using length-weight
relationship and their condition factor. A total of 307 specimens were captured using cast
net for six consecutive months from March 2014 until August 2014. The growth coefficient
(b) from the length-weight equation (W = aLb
) for male and female of C. apogon were
3.150 and 3.185, respectively, indicating positive allometric growth. The condition factor
values of male and female of C. apogon were 1.023 ± 0.111 and 1.026 ± 0.100,
respectively, suggesting that C. apogon is in good condition in Muda Reservoir. The
paucity of research on the autecological study in the Muda Reservoir contributes to the
main reason of performing this research. The findings will serve as baseline information of
this species in Muda Reservoir, as well as for comparative study in the future.

Tarsius bancanus borneanus was first reported by Elliot in 1990 which an endemic species that can be found on the Island of Borneo consisting of Sabah and Sarawak of Malaysia, Brunei Darussalam and Kalimantan, Indonesia. This sub-species has been listed as a totally protected animal under the Sarawak Wild Life Protection Ordinance (1998) and vulnerable by the International Union for Conservation of Nature (IUCN). The present study was conducted at Universiti Putra Malaysia Bintulu Campus (UPMKB), Sarawak from October 2014 till March 2015. Through mark and recapture sampling covering an area of 37 ha of secondary forest patches and 7.13 ha of rehabilitated forest, a total of 16 tarsiers were captured using mist nets while one tarsier was recapture. The population density was 38 individuals/km2 was captured using mist nets in the secondary forest while 28 individuals/km2 was recorded for the rehabilitated forest. Using the catch per unit effort (net hour) method, the average time for capturing tarsiers in the secondary forest patches was 26.6 net hour per animal and 30.0 net hour per animal in the rehabilitated forest. The presented results provides information on the presence of tarsiers in both the secondary and rehabilitated forests of UPMKB, Sarawak, Malaysia which underlines the conservation value of these forested areas.

Fulltext The Effects of Microalgae as Live Food for Brachionus plicatilis (Rotifer) in Intensive Culture System

Rahman ARA, Cob ZC, Jamari Z, Mohamed AM, Toda T, Ross OH

Trop Life Sci Res, 2018 Mar;29(1):127-138.
PMID: 29644020 MyJurnal DOI: 10.21315/tlsr2018.29.1.9

Brachionus plicatilis is used to feed fish and crustacean larvae in the aquaculture industry. It is well established that the type of microalgae may influence rotifer production. This experiment was conducted to determine the effect of five different locally available microalgae species at Fisheries Research Institute (FRI), Kampung Pulau Sayak, Kedah, Malaysia on the instantaneous growth rate (μ) of rotifer. Nannochloris sp., Tetraselmis sp., Isochrysis sp., Chlorella sp., and Nannochloropsis sp. were used as feed at different algae densities (0.1, 0.3, 0.7 and 1.5 × 106 cells/ml) and culture volumes (20, 70 and 210 ml). At algae densities ranging from 0.3 to 1.5 × 106 cells/ml, an average μ value of more than 0.90 per day were recorded for all algae species. However, at density of 0.1 × 106 cells/ml, only Tetraselmis sp. resulted in the significantly highest μ value compared with others (p < 0.05). In terms of volume, smaller culture volume of Tetraselmis sp. (20 ml) showed significantly higher μ compared with higher volume (70 and 210 ml cultures).

Trop Life Sci Res, 2019 Jan;30(1):23-31.
PMID: 30847031 MyJurnal DOI: 10.21315/tlsr2019.30.1.2

Ficus plants are commonly planted as ornamentals along roadsides in Malaysia. In 2010, Ficus plants in Kuala Terengganu were found to be attacked by a moth, identified as Trilocha varians. The larvae of this moth fed on Ficus leaves causing up to 100% defoliation. This study was conducted to determine the life cycle of T. varians under two different environmental temperatures and to control this pest using two different insecticides. Our findings showed that there were significant differences in the time taken for eggs to hatch and larval and pupation period between low and high environmental temperatures. Results also showed that fipronil had lower LT50 and LT95 than malathion. This study provides new information on the life history of T. varians under two different conditions and the efficiency in controlling T. varians larvae using insecticides. The results of this study are important for future management in controlling T. varians population especially in Kuala Terengganu, Malaysia.

Azman N, Zainudin NAIM, Ibrahim WNW

Trop Life Sci Res, 2020 Oct;31(3):91-107.
PMID: 33214858 DOI: 10.21315/tlsr2020.31.3.7

Fumonisin B1 (FB1) is a common mycotoxin produced by Fusarium species particularly F. proliferatum and F. verticillioides. The toxin produced can cause adverse effects on humans and animals. The objectives of this study were to detect the production of FB1 based on the amplification of FUM1 gene, to quantify FB1 produced by the isolates using Ultra-fast Liquid Chromatography (UFLC) analysis, to examine the embryotoxicity effect of FB1 and to determine EC50 toward the larvae of zebrafish (Danio rerio). Fifty isolates of Fusarium species were isolated from different hosts throughout Malaysia. Successful amplification of the FUM1 gene showed the presence of this gene (800 bp) in the genome of 48 out of 50 isolates. The highest level of FB1 produced by F. proliferatum isolate B2433 was 6677.32 ppm meanwhile F. verticillioides isolate J1363 was 954.01 ppm. From the assessment of embryotoxicity test of FB1 on larvae of zebrafish, five concentrations of FB1 (0.43 ppm, 0.58 ppm, 0.72 ppm, 0.87 ppm and 1.00 ppm) were tested. Morphological changes of the FB1 exposed-larvae were observed at 24 to 168 hpf. The mortality rate and abnormality of zebrafish larvae were significantly increased at 144 hpf exposure. Meanwhile, the spontaneous tail coiling showed a significant difference. There were no significant differences in the heartbeat rate. As a conclusion, the presence of FUM1 in every isolate can be detected by FUM1 gene analysis and both of the species produced different concentrations of FB1. This is the first report of FB1 produced by Fusarium species gave a significant effect on zebrafish development.

Impacts of 2 species of predatory Reduviidae on bagworms in oil palm plantations

Jamian S, Norhisham A, Ghazali A, Zakaria A, Azhar B

Insect Sci, 2017 Apr;24(2):285-294.
PMID: 26712127 DOI: 10.1111/1744-7917.12309

Integrated pest management (IPM) is widely practiced in commercial oil palm agriculture. This management system is intended to minimize the number of attacks by pest insects such as bagworms on crops, as well as curb economic loss with less dependency on chemical pesticides. One practice in IPM is the use of biological control agents such as predatory insects. In this study, we assessed the response of predatory natural enemies to pest outbreak and water stress, and document the habitat associations of potential pest predators. The abundances of 2 predatory insect species, namely Sycanus dichotomus and Cosmolestes picticeps (Hemiptera: Reduviidae), were compared bagworm outbreak sites and nonoutbreak sites within oil palm plantations. We also examined habitat characteristics that influence the abundances of both predatory species. We found that the abundance of C. picticeps was significantly higher in bagworm outbreak sites than in nonoutbreak sites. There were no significant differences in the abundance of S. dichotomus among outbreak and non-outbreak sites. Both species responded negatively to water stress in oil palm plantations. Concerning the relationship between predatory insect abundance and in situ habitat quality characteristics, our models explained 46.36% of variation for C. picticeps and 23.17% of variation for S. dichotomus. Both species of predatory insects thrived from the planting of multiple beneficial plants in oil palm plantations. The results suggest that C. picticeps can be used as a biological agent to control bagworm populations in oil palm plantations, but S. dichotomus has no or little potential for such ecosystem service.

Fulltext Comparing and determining factors associated with hypertension self-care profiles of patients in two multi-ethnic Asian countries: cross-sectional studies between two study populations

Wee SY, Salim H, Mawardi M, Koh YLE, Ali H, Shariff Ghazali S, et al.

BMJ Open, 2021 06 14;11(6):e044192.
PMID: 34127489 DOI: 10.1136/bmjopen-2020-044192

OBJECTIVES: To compare the sociodemography, disease characteristics and hypertension self-care profiles and to determine the factors influencing Hypertension Self-Care Profiles (HTN-SCP) in two populations in primary care settings from Singapore and Malaysia.
DESIGN: Cross-sectional, cross national.
SETTING: Multi-centre, primary care clinics Malaysia and Singapore.
PARTICIPANTS: 1123 adults with hypertension enrolled and analysed.
PRIMARY AND SECONDARY OUTCOME MEASURES: Comparison between sociodemography, disease characteristics and the mean scores of HTN-SCP domains (behaviour, motivation and self-efficacy) and the factors influencing hypertension self-care.
RESULTS: 1123 adults with hypertension attending primary care clinics in Malaysia and Singapore were involved. The participants' mean age was 63.6 years (SD 9.7) in Singapore and 60.4 (SD 9.1) in Malaysia. Most of the participants in Singapore had tertiary education (22.3%) compared with Malaysia (13.0%), p<0.001. A higher proportion of participants from Singapore had controlled blood pressure (74.6%) compared with Malaysia (33.8%), p<0.001. The mean total score of HTN-SCP was significantly higher among Singapore participants compared with Malaysia participants 190 (SD 28) versus 184 (SD 23) (p<0.001). Similarly, the mean score for motivation domain 67 (SD 10) versus 65 (SD 9), followed by self-efficacy score 65 (SD 11) versus 62 (SD 9) and behaviour score (58 SD 9 vs 56 SD 9) were higher among Singapore participants. In both countries, the factors which influenced higher HTN-SCP mean scores across all domains were being Indian and had tertiary education.
CONCLUSIONS: The study population in Singapore had a higher HTN-SCP mean score compared with Malaysia. The common factors influencing higher HTN-SCP mean scores at both study sites were ethnicity and level of education. Future intervention to improve self-care among people with hypertension may need to be tailored to their behaviour, motivation and self-efficacy levels.

Patient-centred care in the context of pharmacy consultations: A qualitative study with patients and pharmacists in Malaysia

Ng YK, Shah NM, Loong LS, Pee LT, Chong WW

J Eval Clin Pract, 2020 Dec;26(6):1638-1647.
PMID: 31908087 DOI: 10.1111/jep.13346

RATIONALE, AIMS AND OBJECTIVES: Patient-centred care (PCC) has been increasingly recognized as the standard in current health care, especially when it comes to health communication between patients and health care professionals. The evidence suggests that PCC could potentially improve medication-related outcomes such as medication adherence, disease self-management, and patient-provider relationships. Pharmacists are strategically positioned in the health care system to provide medication management to patients. However, there is a paucity of research regarding PCC in pharmacist-patient consultations. This study aimed to explore the views and experiences of pharmacists and patients on the important aspects of a PCC consultation.
METHODS: A semistructured interview study was conducted among 17 patients and 18 pharmacists in three tertiary hospitals in Malaysia. All interviews were audiotaped and transcribed verbatim. Themes were developed using a constant comparison approach and thematic analysis.
RESULTS: Five main themes emerged from the data, namely, achieving mutual understanding, recognizing individuality, communication style, information giving, and medication decision making. For both pharmacists and patients, a PCC consultation should promote mutual understanding and non-judgmental discussions. Communication was an important element to bridge the gap between patients' and pharmacists' expectations. Patients emphasized the importance of emotional aspects of the consultation, while pharmacists emphasized the importance of evidence-based information to support patient engagement and information needs.
CONCLUSIONS: Comparison of pharmacists' and patients' views provided insight towards important aspects of PCC in pharmacist-patient consultations. It was suggested that PCC is not a one-sided approach but rather a patient-provider collaboration to optimize the consultation. Further research can be done to improve the integration of PCC in the local health care context, including pharmacist consultations.

A comparison of different standard-setting methods for professional qualifying dental examination

Abd-Rahman ANA, Baharuddin IH, Abu-Hassan MI, Davies SJ

J Dent Educ, 2021 Jul;85(7):1210-1216.
PMID: 33792052 DOI: 10.1002/jdd.12600

BACKGROUND: The outcome of assessments is determined by the standard-setting method used. Standard setting is the process of deciding what is good enough. A cutoff score of 50% was commonly used in dental schools in Malaysia. This study aims to compare the conventional, norm-referenced, and modified-Angoff standard-setting methods.
METHODS: The norm-referenced method of standard setting was applied to the real scores of 40 final-year dental students on a multiple-choice question (MCQ), a short answer question (SAQ), and an objective structured clinical examination (OSCE). A panel of 10 judges set the standard using the modified-Angoff method for the same paper in one sitting. One judge set the passing score of 10 OSCE questions after 2 weeks. A comparison of the grades and pass/fail rates derived from the absolute standard, norm-referenced, and modified-Angoff methods was made. The intra-rater and inter-rater reliabilities of the modified-Angoff method were assessed.
RESULTS: The passing rate for the absolute standard was 100% (40/40), for the norm-referenced method it was 62.5% (25/40), and for the modified-Angoff method it was 80% (32/40). The modified-Angoff method had good inter-rater reliability of 0.876 and excellent test-retest reliability of 0.941.
CONCLUSION: There were significant differences in the outcomes of these three standard-setting methods, as shown by the difference in the proportion of candidates who passed and failed the assessment. The modified-Angoff method was found to have good reliability for use with a professional qualifying dental examination.

Toxicity and cross-neutralization of snake venoms from two lesser-known arboreal pit vipers in Southeast Asia: Trimeresurus wiroti and Trimeresurus puniceus

Lee LP, Tan KY, Tan CH

Toxicon, 2020 Oct 15;185:91-96.
PMID: 32585219 DOI: 10.1016/j.toxicon.2020.06.012

The lesser-known Sundaic lance-headed pit vipers Trimeresurus wiroti (Malaysia) and Trimeresurus puniceus (Indonesia) contribute to the disease burden of snakebite envenomation in Southeast Asia, but their venom toxicity and neutralization remain insufficiently investigated. This study demonstrated that both venoms were procoagulant (involving thrombin-like activity), hemorrhagic, and lethal to mice, with T. wiroti venom being more lethal (LD50 = 0.78 μg/g c.f. 1.21 μg/g). The hetero-specific antivenom from Thailand, Green Pit Viper Antivenom (GPVAV, raised against Trimeresurus albolabris) cross-reacted with T. wiroti and T. puniceus venoms with a higher efficacy of immunological binding activity for the latter. The antivenom was also effective in cross-neutralizing the procoagulant, hemorrhagic and lethal effects of the venoms. In lethality neutralization, GPVAV showed a potency of 0.79-1.05 mg venom per mL antivenom, corresponding to the complete neutralization of approximately 8-10 mg venom per unit vial of antivenom for T. wiroti and T. puniceus venoms. Taken together, it was inferred that T. wiroti, T. puniceus, and T. albolabris venoms share common toxin epitopes, thus enabling the cross-neutralization observed. These findings suggest that GPVAV may be potentially useful in the management of envenomation by T. wiroti and T. puniceus while awaiting clinical trial and validation.

Lau KW, Chen CD, Lee HL, Izzul AA, Asri-Isa M, Zulfadli M, et al.

Trop Biomed, 2013 Mar;30(1):36-45.
PMID: 23665706 MyJurnal

The aim of the present study was to determine the vertical distribution and abundance of Aedes mosquitoes in multiple storey buildings in Selangor and Kuala Lumpur, Malaysia. Ovitrap surveillance was conducted for 4 continuous weeks in multiple storey buildings in 4 residential areas located in Selangor [Kg. Baiduri (KB)] and Kuala Lumpur [Student Hostel of University of Malaya (UM), Kg. Kerinchi (KK) and Hang Tuah (HT)]. The results implied that Aedes mosquitoes could be found from ground floor to highest floor of multiple storey buildings and data from different elevation did not show significant difference. Ovitrap index for UM, KB, HT and KK ranged from 0 - 29.17%, 0 - 55.56%, 8.33 - 83.33% and 0 - 91.17% respectively. Aedes aegypti and Aedes albopictus were found breeding in HT, KK and KB; while only Ae. albopictus was obtained from UM. The results indicate that the invasion of Aedes mosquitoes in high-rise apartments could facilitate the transmission of dengue virus and new approaches to vector control in this type of residential area should be developed.
