Fulltext Reliability and validity of the Malay version of the General Health Questionnaire (GHQ - 12) among urological patients

Quek KF, Low WY, Razack AH, Chua CB, Loh CS

Med J Malaysia, 2002 Jun;57(2):169-77.
PMID: 24326647

The aim of the study was to validate the Malay version of the General Quentionnaire (GHQ-12) in patients with psychiatric morbidity secondary to urological disorder. Validity and reliability were studied in patients with lower urinary tract symptoms (LUTS) and patients without LUTS. Internal consistency was excellent. A high degree of internal consistency was observed for each of the 12 items and total scores (Cronbach's alpha value = 0.50 and higher and 0.65 respectively. Test-retest correlation coefficient for the 12 items scores was highly significant. Intraclass correlation coefficient was high (ICC=0.47 and above). A significant level between baseline and post-treatment scores were observed across 3 items in the surgical group. The Mal-GHQ-12 is a suitable, reliable, valid and sensitive to clinical change in the Malaysian population.

Fulltext The clinical significance of the branching pattern of the facial nerve in Malaysian subjects

Myint K, Azian AL, Khairul FA

Med J Malaysia, 1992 Jun;47(2):114-21.
PMID: 1494331

Fine dissection was carried out in 79 facial halves from formalin fixed Malaysian adult cadavers of various races, to trace the extracranial part of the facial nerve and its peripheral branches. The facial nerve trunk, after leaving the stylomastoid foramen was located at a depth of 1 to 2 cm from the skin in the vagino-mastoid angle. It bifurcates at the posterior border of the ramus of the mandible and in 3.8% trifurcation was found. Mean distance of bifurcation from the angle of the mandible was 28.06 mm and 81.0% were within the range of 21 to 35 mm. The branching patterns were classified into six types, and the frequency of occurrence was type I 11.39%, type II 15.9%, type III 34.18%, type IV 18.98%, type V 7.59% and type VI 12.67%. Type I, a classical text book pattern was found to be one of the least common patterns. There is no significant difference in percentage of each type between the present study and that of Koreans, though some differences with Caucasians were noted in three uncommon types. The frontal branch could be outlined between the two diverging lines from the earlobe to the lateral ends of the eyebrow and the highest frontal crease. Posterior to the facial artery, the mandibular branch was seen passing below the inferior border of the mandible in 20%; anterior to the artery, this nerve divides into one to four branches. In almost all the cases, branches to the mentalis and the depressor labii inferioris muscles and infrequently branches to the depressor angular oris were seen below the inferior border of the mandible.(ABSTRACT TRUNCATED AT 250 WORDS)

Fulltext Uncertainty in identifying local extinctions: the distribution of missing data and its effects on biodiversity measures

Boakes EH, Fuller RA, McGowan PJ, Mace GM

Biol Lett, 2016 Mar;12(3).
PMID: 26961894 DOI: 10.1098/rsbl.2015.0824

Identifying local extinctions is integral to estimating species richness and geographic range changes and informing extinction risk assessments. However, the species occurrence records underpinning these estimates are frequently compromised by a lack of recorded species absences making it impossible to distinguish between local extinction and lack of survey effort-for a rigorously compiled database of European and Asian Galliformes, approximately 40% of half-degree cells contain records from before but not after 1980. We investigate the distribution of these cells, finding differences between the Palaearctic (forests, low mean human influence index (HII), outside protected areas (PAs)) and Indo-Malaya (grassland, high mean HII, outside PAs). Such cells also occur more in less peaceful countries. We show that different interpretations of these cells can lead to large over/under-estimations of species richness and extent of occurrences, potentially misleading prioritization and extinction risk assessment schemes. To avoid mistakes, local extinctions inferred from sightings records need to account for the history of survey effort in a locality.

The mode of inheritance of ovalocytosis/elliptocytosis in Malaysian Orang Asli families

Fix AG, Baer AS, Lie-Injo LE

Hum Genet, 1982;61(3):250-3.
PMID: 7173868 DOI: 10.1007/bf00296452

Hereditary ovalocytosis/elliptocytosis occurs in polymorphic frequencies among several Malaysian populations and also in Melanesia. Although the condition has been described as an autosomal dominant, Melanesian family studies suggest that it is inherited recessively. Based on 75 Orang Asli families, it is shown that the Malaysian form of elliptocytosis is most likely inherited as an autosomal dominant. It appears, therefore, that either the inference of recessive inheritance in Melanesians is incorrect or that the ovalocytosis/elliptocytosis phenotypes are due to distinct genetic entities in the two regions.

Fulltext How E-Learning Environmental Stimuli Influence Determinates of Learning Engagement in the Context of COVID-19? SOR Model Perspective

Yang J, Peng MY, Wong S, Chong W

Front Psychol, 2021;12:584976.
PMID: 33868072 DOI: 10.3389/fpsyg.2021.584976

The COVID-19 pandemic at the beginning of 2020 has changed the conventional learning mode for most students at schools all over the world, and the e-learning at home has become a new trend. Taking Chinese college students as the research subject and drawing on the stimulus-organism-response (S-O-R) model, this paper examines the relationship between the peer referent, perceived closeness, and perceived control and the learning engagement. Using data from 377 college students who have used e-learning, this study shows that perceived closeness, perceived control, and peer referents in e-learning have a positive effect on the self-efficacy and well-being of students, thus improving students' enthusiasm for learning. Our intent is to assist researchers, instructors, designers, and others in identifying effective methods to conceptualize and measure student engagement in e-learning.

Cheiloscopy is recognized as a tool for personal identification due to its strength in criminalistics. In this study, the lip print of Malaysian Chinese population in Klang Valley was used for gender determination using lipstick-cellophane technique. 412 subjects (203 males and 209 females) were selected conveniently. Lipstick was first applied on the lips and the lip print was lifted using cellophane tape prior to pasting them onto a plain A4 paper and analysis using magnifying glass. Six topography areas of lip prints were classified using Suzuki and Tsuchihashi’s classification, including upper left, upper middle, upper right, lower right, lower middle and lower left. Chi-square test showed that all lip sections were significantly different from each other (p < 0.05). Type II was the dominant pattern in four lip sections for both genders: upper left (male 81.3%, female 57.4%), upper right (male 71.9%, female 42.9%), lower left (male 98.0%, female 90.0%) and lower right (male 96.1%, female 86.1%). Type IV was the dominant pattern for both middle part of the lips; upper middle (male 56.2%, female 50.7%) and lower middle (male 62.6%, female 50.2%). The results showed that gender can be differentiated based on lip print patterns. This finding suggested that cheiloscopy could be used in aiding personal identification for forensic investigation.

Fulltext Selected recommendations from international guidelines on obstructive sleep apnoea

Nurul Yaqeen Mohd Esa

Journal of Clinical and Health Sciences, 2017;2:19-25.

Obstructive sleep apnoea (OSA) is increasingly seen as a major health threat globally.
However, it is still underdiagnosed mainly among Asian population partly due to lack of
understanding on the pathophysiology, and limited access to the diagnostic and management
aspect of the disease. Recurring complete and/or partial collapses of the upper airways define
OSA. Based on the number of apnoeas and/or hypopnoeas per hour of sleep, OSA is
categorized as mild, moderate and severe. Both the American Association of Sleep Medicine
(AASM) and American College of Physicians (ACP) has published guidelines regarding the
management of OSA in adults. Three recommendations have been suggested by the
guidelines which can be used to tailor the management of OSA. The aim of this article is to
select relevant recommendations from these guidelines in epidemiology, pathophysiology,
diagnostic procedures and treatment for proper management of OSA, while considering
specific patient populations, such as hypertensive, diabetic, obese and Asian patients.

Reactions to male-favouring versus female-favouring sex differences: A pre-registered experiment and Southeast Asian replication

Stewart-Williams S, Chang CYM, Wong XL, Blackburn JD, Thomas AG

Br J Psychol, 2021 May;112(2):389-411.
PMID: 32701171 DOI: 10.1111/bjop.12463

Two studies investigated (1) how people react to research describing a sex difference, depending on whether that difference favours males or females, and (2) how accurately people can predict how the average man and woman will react. In Study 1, Western participants (N = 492) viewed a fictional popular-science article describing either a male-favouring or a female-favouring sex difference (i.e., men/women draw better; women/men lie more). Both sexes reacted less positively to the male-favouring differences, judging the findings to be less important, less credible, and more offensive, harmful, and upsetting. Participants predicted that the average man and woman would react more positively to sex differences favouring their own sex. This was true of the average woman, although the level of own-sex favouritism was lower than participants predicted. It was not true, however, of the average man, who - like the average woman - reacted more positively to the female-favouring differences. Study 2 replicated these findings in a Southeast Asian sample (N = 336). Our results are consistent with the idea that both sexes are more protective of women than men, but that both exaggerate the level of same-sex favouritism within each sex - a misconception that could potentially harm relations between the sexes.

Fulltext A Current Update on the Distribution, Morphological Features, and Genetic Identity of the Southeast Asian Mahseers, Tor Species

Jaafar F, Na-Nakorn U, Srisapoome P, Amornsakun T, Duong TY, Gonzales-Plasus MM, et al.

Biology (Basel), 2021 Apr 01;10(4).
PMID: 33915909 DOI: 10.3390/biology10040286

The king of rivers or mahseer comprises three genera: Tor, Neolissochilus, and Naziritor, under the Cyprinidae family. The Tor genus has been classified as the true mahseer due to the presence of a median lobe among the three genera. The Tor species are widely distributed across Southeast (SE) Asia, and 13 Tor species have been reported previously: Tor ater, Tor dongnaiensis, Tor douronensis, Tor laterivittatus, Tor mosal, Tor mekongensis, Tor putitora, Tor sinensis, Tor soro, Tor tambra, Tor tambroides, Tor tor and Tor yingjiangensis. However, the exact number of valid Tor species remains debatable. Different and unstandardized approaches of applying genetic markers in taxonomic identification and morphology variation within the same species have further widened the gap and ameliorated the instability of Tor species taxonomy. Therefore, synchronized and strategized research among Tor species researchers is urgently required to improve and fill the knowledge gap. This review is a current update of SE Asia's Tor species, outlining their distribution, morphology, and genetic identification. In addition, the present review proposes that there are ten valid Tor species in the SE Asian region. This list will serve as a template and standard to improve the taxonomy of the SE Asian Tor species, which could serve as a basis to open new directions in Tor research.

Associations between self-reported and objective face recognition abilities are only evident in above- and below-average recognisers

Estudillo AJ, Wong HK

PeerJ, 2021;9:e10629.
PMID: 33510971 DOI: 10.7717/peerj.10629

The 20-Item Prosopagnosia Items (PI-20) was recently introduced as a self-report measure of face recognition abilities and as an instrument to help the diagnosis of prosopagnosia. In general, studies using this questionnaire have shown that observers have moderate to strong insights into their face recognition abilities. However, it remains unknown whether these insights are equivalent for the whole range of face recognition abilities. The present study investigates this issue using the Mandarin version of the PI-20 and the Cambridge Face Memory Test Chinese (CFMT-Chinese). Our results showed a moderate negative association between the PI-20 and the CFMT-Chinese. However, this association was driven by people with low and high face recognition ability, but absent in people within the typical range of face recognition performance. The implications of these results for the study of individual differences and the diagnosis of prosopagnosia are discussed.

Fulltext Defining the endoscopic ultrasound features of chronic pancreatitis in Asians: a multicenter validation study

Koh CJ, Lakhtakia S, Kida M, Lesmana CRA, Ang TL, Vu CKF, et al.

Endoscopy, 2021 06;53(6):595-602.
PMID: 32650341 DOI: 10.1055/a-1217-3112

BACKGROUND: Although endoscopic ultrasound (EUS) features and criteria have been described in chronic pancreatitis, challenges remain with interoperator variability and ease of adoption. The aim of this study was to define and validate the EUS features of chronic pancreatitis in a multicenter prospective study in Asia.
METHOD: The study was divided into two parts: the first part was conducted to derive the EUS features of chronic pancreatitis with adequate interoperator agreement; the second was to prospectively evaluate these features in a multicenter cross-sectional study and determine the optimal combination of features for the diagnosis of chronic pancreatitis. Prospectively enrolled cases had standard internationally validated radiologic or histologic features of chronic pancreatitis, and controls were patients without chronic pancreatitis who underwent EUS examination.
RESULTS: The top six EUS features that had good interobserver agreement (mean kappa 0.73, range 0.60 - 0.90) were selected to be further evaluated in part II of the study. These included: hyperechoic foci with shadowing, lobularity with honeycombing, cysts, dilated main pancreatic duct, dilated side branches, and calculi in the main pancreatic duct. A total of 284 subjects (132 cases, 152 controls) were enrolled from 12 centers in Asia. All six features had high accuracy ranging from 63.3 % to 89.1 %. Two or more of these six EUS features accurately defined chronic pancreatitis (sensitivity 94.7 %, specificity 98.0 %), with an area under the receiver operating curve of 0.986.
CONCLUSION: This multicenter Asian study characterized and defined the EUS features of chronic pancreatitis. This provides a useful tool in clinical practice and further research in pancreatic cancer surveillance.

This study aims to present a quick overview of the novel coronavirus (afterward COVID-19) which triggers from Wuhan, spread approximately 213 countries and territories around the globe, and still currently ongoing. Particularly, we are interested to investigate the economic perspective of COVID-19. This paper uses data from online published articles and current media sources, as the COVID-19 situation is unfolding yet. To deeply explore the said matter, we divide the economic impact into six dimensions that is, Chinese economy, Central Asian economies, South Asian economies, South East and West Asian economies, European economies, Northern African, and Middle Eastern economies. The paper concludes that epidemic situations like COVID-19 severely affect economies around the globe. The basic reasons behind such severity are immobility of labor, reduction in productivity, discontinuation of the supply chain, a decline in exports, uncertainty, and so on. This study is quite important for businesses and policymakers to estimate and plan current and post-COVID-19 situations.

Fulltext A review of adult obesity research in Malaysia

Lim KG

Med J Malaysia, 2016 06;71(Suppl 1):1-19.
PMID: 27801384 MyJurnal

A literature search of articles as detailed in the paper Bibliography of clinical research in Malaysia: methods and brief results, using the MESH terms Obesity; Obesity, Abdominal; and Overweight; covering the years 2000 till 2015 was undertaken and 265 articles were identified. Serial population studies showed that the prevalence of obesity increased rapidly in Malaysia in the last decade of the twentieth century. This follows the rising availability of food per capita which had been begun two to three decades previously. Almost every birth cohort, even up to those in their seventh decade increased in prevalence of overweight and obesity between 1996 and 2006. However, the rise in prevalence in obesity appears to have plateaued after the first decade of the twentieth century. Women are more obese than men and Malays and Indians are more obese than Chinese. The Orang Asli (Aborigines) are the least obese ethnic group in Malaysia but that may change with socioeconomic development. Neither living in rural areas nor having low income protects against obesity. On the contrary, a tertiary education and an income over RM4,000/month is associated with less obesity. Malaysians are generally not physically active enough, in the modes of transportation they use and how they use their leisure time. Other criteria and measures of obesity have been investigated, such as the relevance of abdominal obesity, and the Asian criteria or Body Mass Index (BMI) cut-offs value of 23.0 kg/m2 for overweight and 27.0 kg/m2 for obesity, with the view that the risk of diabetes and other chronic diseases start to increase at lower values in Asians compared to Europeans. Nevertheless the standard World Health Organization (WHO) guidelines for obesity are still most widely used and hence is the best common reference. Guidelines for the management of obesity have been published and projects to combat obesity are being run. However, more effort needs to be invested. Studies on intervention programmes showed that weight loss is not easy to achieve nor maintain. Laboratory research worldwide has uncovered several genetic and biochemical markers associated with obesity. Similar studies in Malaysia have found some biomarkers with an association to obesity in the local population but none of great significance.

Fulltext Female Physical Attractiveness and Body Image Disorders in Malaysia

Virens, S.

Malaysian Journal of Psychiatry, 2006;14(1):3-7.
MyJurnal

Preferred body sizes appear to decrease markedly with increasing exposure to contemporäry notions of slimness and economic modernity, and reduce even further in industrial settings as socio-economic status increases. Recently a study examining physical attractiveness preferences in Britain and Malaysia, shows that preference for slim ideals varies according to socio-economic status. Malaysians in
Britain and Kuala Lumpur preferred slimmer female bodies than observers in semiurban Kota Kinabalu, who in turn preferred slimmer figures than rural observers in East Malaysia. This study has important implications for the study of body image and eating disorders in Malaysia.

Fulltext Mandarin speech perception tests for Malaysian Chinese children

Cila Umat, Chong, Sheue Lih, Siti Zamratol-Mai Sarah Mukari

Jurnal Sains Kesihatan Malaysia, 2010;8(1):31-37.
MyJurnal

The study aimed to develop Mandarin speech perception tests for Malaysian Chinese children. Two tests were developed which were the Syllabic Pattern Perception Test (SPPT) and the Tone Perception Test (TPT). Both tests were designed for children aged between three to six years-old. A total of 80 normal hearing children aged 3 years to 6 years and 11 months from several kindergartens around Kuala Lumpur and Ipoh participated in this study. Results showed that the mean scores for the SPPT did not differ significantly across age (p > 0.05), possibly due to a ceiling effect. Although the SPPT showed relatively low test-retest and inter-rater Spearman correlation coefficients (r = 0.68 for correct syllable pattern response and r = 0.38 for correct item response), the scores were highly repeatable in both test-retest and interrater conditions. For the TPT, the mean scores of five and six year old children were significantly higher than three year old subjects while the mean score of four year old subjects was significantly poorer than the six years old. The test-retest and inter-rater reliability were high and the coefficients approximated 0.80 (p < 0.05). For both tests, gender and dialects or languages used as the second language did not have significant effect on the test scores. Content validity evidence was also collected from a group of panelists. In conclusion, SPPT and TPT are reliable and valid Mandarin speech tests to be used on Malaysian Chinese children who speak Mandarin.
