  4. Prevalence and patterning of maxillary premolar accessory ridges (MxPARs) in several human populations
    Mihailidis S, Scriven G, Khamis M, Townsend G
    Am. J. Phys. Anthropol., 2013 Sep;152(1):19-30.
    PMID: 23913636 DOI: 10.1002/ajpa.22323
    We present new data on the prevalence and patterning of the maxillary premolar accessory ridge (MxPAR), a common but understudied morphological dental trait that is expressed as a linear elevation extending from the buccal cusp ridge to the medial sulcus of maxillary premolar teeth. A total of 579 sets of dental casts, representing six ethnic groups, were scored using the five-grade system proposed by Burnett et al. (2010). The frequency and distribution of the MxPAR were determined by tooth type, sex, side, locus and ethnicity, and the applicability of the scoring system was assessed. The MxPAR was found in approximately two-thirds of premolar teeth, more often on second than first premolars, and more often on the distal aspect of the occlusal surface than the mesial. There was some evidence that more pronounced forms of the feature occurred more often in males than females, and that there may be some directionality in its expression between sides. Variation was also noted in the frequency of occurrence and degree of expression of the MxPAR between ethnic groups. Intra- and inter-observer concordance rates for scoring the MxPAR were low, confirming that it was difficult to score the trait identically on two different occasions. Our findings have clarified the distribution of the MxPAR within the dentition and between ethnic groups, and highlighted the need for researchers to carry out thorough replicability studies and to decide on an appropriate breakpoint for determining presence or absence of this feature before embarking on genetic studies or bio-distance analyses.

    Ngeow WC, Aljunid ST
    Indian J Dent Res, 2009 Jul-Sep;20(3):313-9.
    PMID: 19884715 DOI: 10.4103/0970-9290.57372
    OBJECTIVE: This study was done to establish the craniofacial anthropometric norms of the young adult (18- 25 years) Malaysian Indian.
    MATERIALS AND METHODS: The study group consisted of convenient samples of 100 healthy volunteers, with equal number of female and male subjects who had no history of mixed racial-parentage. Twenty-two linear measurements were taken twice from 28 landmarks over six craniofacial regions. The methodology and evaluation of indices of the craniofacial region was adapted from Hajnis et al.
    RESULTS: The minimum measurements are always contributed by the female Indian except for the nose height (n-sn), (left) eye fissure length (ex-en), upper vermillion height (ls-sto), and lower vermillion height (sto-li). There is a gender difference in all the measurements except the (left) eye fissure height (independent t-test; P < 0.05). The Malaysian Indians exhibit some North American White Caucasian (NAWC) features in all regions. The cephalic index indicates a brachycephalic or relatively short wide head with a tendency towards mesocephaly. From the low nasal index, the Malaysian Indian female have a nose that is narrow or leptorrhin similar to the NAWCs. The lower value of the upper lip height to mouth width index in the Indian female indicates a relatively shorter upper lip height compared to the mouth width, also similar to the NAWC.
    CONCLUSION: This study establishes the craniofacial anthropometric norms of the Malaysian Indian over 22 parameters. Male in general has a significantly higher measurement than female. The Malaysian Indians do exhibit some NAWC features.

    Kwan MK, Chiu CK, Chan CY, Zamani R, Hansen-Algenstaedt N
    Eur Spine J, 2016 06;25(6):1745-53.
    PMID: 26223743 DOI: 10.1007/s00586-015-4150-4
    PURPOSE: To directly compare the safety of fluoroscopic guided percutaneous thoracic pedicle screw placement between Caucasians and Asians.

    METHODS: This was a retrospective computerized tomography (CT) evaluation study of 880 fluoroscopic guided percutaneous pedicle screws. 440 screws were inserted in 73 European patients and 440 screws were inserted in 75 Asian patients. Screw perforations were classified into Grade 0: no violation; Grade 1: <2 mm perforation; Grade 2: 2-4 mm perforation; and Grade 3: >4 mm perforation. For anterior perforations, the pedicle perforations were classified into Grade 0: no violation, Grade 1: <4 mm perforation; Grade 2: 4-6 mm perforation; and Grade 3: >6 mm perforation.

    RESULTS: The inter-rater reliability was adequate with a kappa value of 0.83. The mean age of the study group was 58.3 ± 15.6 years. The indications for surgery were tumor (70.3 %), infection (18.2 %), trauma (6.8 %), osteoporotic fracture (2.7 %) and degenerative diseases (2.0 %). The overall screw perforation rate was 9.7 %, in Europeans 9.1 % and in Asians 10.2 % (p > 0.05). Grade 1 perforation rate was 8.4 %, Grade 2 was 1.2 % and Grade 3 was 0.1 % with no difference in the grade of perforations between Europeans and Asians (p > 0.05). The perforation rate was the highest in T1 (33.3 %), followed by T6 (14.5 %) and T4 (14.0 %). Majority of perforations occurred medially (43.5 %), followed by laterally (25.9 %), and anteriorly (23.5 %). There was no statistical significant difference (p > 0.05) in the perforation rates between right-sided pedicle screws and left-sided pedicle screws (R: 10.0 %, L: 9.3 %).

    CONCLUSIONS: There were no statistical significant differences in the overall perforation rates, grades of perforations, direction of perforations for implantation of percutaneous thoracic pedicle screws insertion using fluoroscopic guidance between Europeans and Asians. The safety profile for this technique was comparable to the current reported perforation rates for conventional open pedicle screw technique.

  8. Fulltext Bedtime routines for young children: a dose-dependent association with sleep outcomes
    Mindell JA, Li AM, Sadeh A, Kwon R, Goh DY
    Sleep, 2015 May;38(5):717-22.
    PMID: 25325483 DOI: 10.5665/sleep.4662
    Establishment of a consistent bedtime routine (the activities that occur right before lights out) is often recommended as part of healthy sleep habits. However, no studies have investigated the dose-dependent association of a bedtime routine with sleep outcomes, especially in young children for whom they are particularly recommended. Thus, the aim of this study was to examine the associations of a consistent bedtime routine with sleep outcomes in young children (ages 0 through 5 y) in a large global sample and assess whether there is a dose-dependent relationship between the frequency of a bedtime routine both concurrently and retrospectively with sleep outcomes.

  10. A comparison of smoking behaviour characteristics between Caucasian smokers in the United Kingdom and Malay smokers in Malaysia
    Robson N, Bond A, Wolff K
    Prev Med, 2013;57 Suppl:S8-10.
    PMID: 23624111 DOI: 10.1016/j.ypmed.2013.04.010
    OBJECTIVES: There is evidence that smoking behaviour differs by ethnicity. This study aims to compare smoking behaviour characteristics between Caucasian and Malay smokers.
    METHODS: A cross sectional survey, involving 175 smokers attending smoking cessation clinics at the Institute of Psychiatry, London, United Kingdom and University Malaya, Kuala Lumpur, Malaysia between May 2005 and February 2007. Data on demographics, smoking history, nicotine dependence and smoking behaviour were collected.
    RESULTS: All participants were males, mean age 30.7 ± 10.3 years. Caucasians initiated smoking significantly earlier (mean age 14.8 ± 2.8 years) (p = 0.001) and smoked regularly significantly earlier (mean age 17.3 ± 3.5) (p = 0.003) than Malays (mean starting age 16.9 ± 4.4 years and mean age regular use 19.5 ± 4.5 years), respectively. Caucasians smoked less for social integration than Malays (p = 0.03) but smoked more for regulation of negative affect than Malays (p = 0.008) and smoked more for hedonism than Malays (p < 0.001).
    CONCLUSION: Malays smoke as a means of socially integrating. This has important public health implications. Social reasons and the social environment play a role in smoking uptake, smoking maintenance and smoking cessation and this should be borne in mind for strategies planning to promote smoking cessation.

  11. Fulltext Public perceptions and attitudes toward thalassaemia: Influencing factors in a multi-racial population
    Wong LP, George E, Tan JA
    BMC Public Health, 2011;11:193.
    PMID: 21447191 DOI: 10.1186/1471-2458-11-193
    Thalassaemia is a common public health problem in Malaysia and about 4.5 to 6% of the Malays and Chinese are carriers of this genetic disorder. The major forms of thalassaemia result in death in utero of affected foetuses (α-thalassaemia) or life-long blood transfusions for survival in β-thalassaemia. This study, the first nationwide population based survey of thalassaemia in Malaysia, aimed to determine differences in public awareness, perceptions and attitudes toward thalassaemia in the multi-racial population in Malaysia.

    PMID: 20138578 DOI: 10.1016/j.sleep.2009.04.012
    BACKGROUND:
    To characterize cross-cultural sleep patterns and sleep problems in a large sample of children ages birth to 36 months in multiple predominantly-Asian (P-A) and predominantly-Caucasian (P-C) countries.

    METHODS:
    Parents of 29,287 infants and toddlers (predominantly-Asian countries/regions: China, Hong Kong, India, Indonesia, Korea, Japan, Malaysia, Philippines, Singapore, Taiwan, Thailand, Vietnam; predominantly-Caucasian countries: Australia, Canada, New Zealand, United Kingdom, United States) completed an internet-based expanded version of the Brief Infant Sleep Questionnaire.

    RESULTS:
    Overall, children from P-A countries had significantly later bedtimes, shorter total sleep times, increased parental perception of sleep problems, and were more likely to both bed-share and room-share than children from P-C countries, p

    Ohn Mar S, Malhi F, Syed Rahim SH, Chua CT, Sidhu SS, Sandheep S
    Asia Pac J Public Health, 2015 Nov;27(8 Suppl):19S-25S.
    PMID: 25972428 DOI: 10.1177/1010539515586457
    This cross-sectional study investigated the use of alternative medications to alleviate menopause-related symptoms among Malay, Chinese, and Indian women of Ipoh city. The prevalence, types, effectiveness, and associated factors were determined. The prevalence of alternative medication use was 41.4%. Evening primrose oil (EPO) was the most popular medication used (18.1%), followed by soy-based products (12.3%), green tea (6.8%), and gingko (5.8%). The medication was reported to be highly effective by 58.3% of soya bean diet users and 41.1% of EPO users. Significant variables associated with the use were Chinese or Indian ethnicity (P < .001), age between 50 and 54 years (P < .01), lower self-health rating (P < .05), education level of diploma or professional degree (P < .05), employment as professionals or entrepreneurs (P < .05), and the use of hormone replacement therapy (P < .05). Regression analysis showed that Chinese and Indians had significantly higher odds for the use than Malays (Chinese: odds ratio [OR] = 4.33, 95% confidence interval [CI] = 2.392-7.837; Indians: OR = 3.248, 95% CI = 1.586-6.654).

  15. Fulltext Association of the lupus low disease activity state (LLDAS) with health-related quality of life in a multinational prospective study
    Golder V, Kandane-Rathnayake R, Hoi AY, Huq M, Louthrenoo W, An Y, et al.
    Arthritis Res Ther, 2017 03 20;19(1):62.
    PMID: 28320433 DOI: 10.1186/s13075-017-1256-6
    BACKGROUND: Systemic lupus erythematosus (SLE) is associated with significant impairment of health-related quality of life (HR-QoL). Recently, meeting a definition of a lupus low disease activity state (LLDAS), analogous to low disease activity in rheumatoid arthritis, was preliminarily validated as associated with protection from damage accrual. The LLDAS definition has not been previously evaluated for association with patient-reported outcomes. The objective of this study was to determine whether LLDAS is associated with better HR-QoL, and examine predictors of HR-QoL, in a large multiethnic, multinational cohort of patients with SLE.
    METHODS: HR-QoL was measured using the Medical Outcomes Study 36-item short form health survey (SF-36v2) in a prospective study of 1422 patients. Disease status was measured using the SLE disease activity index (SLEDAI-2 K), physician global assessment (PGA) and LLDAS.
    RESULTS: Significant differences in SF-36 domain scores were found between patients stratified by ethnic group, education level and damage score, and with the presence of active musculoskeletal or cutaneous manifestations. In multiple linear regression analysis, Asian ethnicity (p

  16. A nationwide epidemiological study on the prevalence of multiple sclerosis and neuromyelitis optica spectrum disorder with important multi-ethnic differences in Malaysia
    Viswanathan S, Wah LM
    Mult Scler, 2019 10;25(11):1452-1461.
    PMID: 30113245 DOI: 10.1177/1352458518792430
    OBJECTIVES: This study looked at observed crude prevalence/incidence of multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) in Malaysia and identified any inter-ethnic differences for MS/NMOSD.

    METHODS: This was a nationwide tertiary hospital-based retrospective cross-sectional study using the capture-recapture method. It looked at the estimated crude prevalence of confirmed MS and NMOSD and annual incidence on 29 December 2017. Recapture of data was done between February and March 2018 on 1 March 2018. Public and referring private institutions were accessed.

    RESULTS: The survey identified 767 MS and 545 NMOSD subjects, with crude prevalence rates of 2.73 per 100,000 (95% confidence interval (CI): 2.53; 2.92 per 100,000 population) and 1.94 per 100,000 (95% CI: 1.77; 2.10 per 100,000 population) with observed crude annual incidence of 0.55 (95% CI: 0.43; 0.58) for MS and 0.39 per 100,000 (95% CI: 0.35; 0.47) for NMOSD. The MS:NMOSD ratios were 1.4:1.0. The capture-recapture method revealed 913 MS (95% CI: 910; 915.9) and 580 (95% CI: 578.8; 581.2) NMOSD with prevalence per 100,000 of 3.26 (95% CI: 3.05; 3.47) and 2.07 (95% CI: 1.90; 2.24), respectively. In the MS group, 59.4% were Malay, 16.6% Chinese, 20.5% Indian, and 3.5% were from indigenous groups. In the NMOSD group, 47.3% were Malay, 46.9% Chinese, 3.5% Indian, and 2.3% were from other indigenous groups. The ratio of NMOSD to MS among the Chinese was 2:1, but the ratio of MS to NMOSD among the Malays was 1.8:1, and that in Indians was 8.3:1.

    CONCLUSION: There is a modest increase in the prevalence of MS and NMOSD in Malaysia with inter-ethnic differences for MS/NMOSD.

  17. Fulltext Cross-sectional analysis of ethnic differences in fall prevalence in urban dwellers aged 55 years and over in the Malaysian Elders Longitudinal Research study
    Alex D, Khor HM, Chin AV, Hairi NN, Othman S, Khoo SPK, et al.
    BMJ Open, 2018 07 17;8(7):e019579.
    PMID: 30018093 DOI: 10.1136/bmjopen-2017-019579
    OBJECTIVES: Falls represent major health issues within the older population. In low/middle-income Asian countries, falls in older adults remain an area which has yet to be studied in detail. Using data from the Malaysian Elders Longitudinal Research (MELoR), we have estimated the prevalence of falls among older persons in an urban population, and performed ethnic comparisons in the prevalence of falls.

    DESIGN: Cross-sectional analysis was carried out using the first wave data from MELoR which is a longitudinal study.

    SETTING: Urban community dwellers in a middle-income South East Asian country.

    PARTICIPANTS: 1565 participants aged ≥55 years were selected by simple random sampling from the electoral rolls of three parliamentary constituencies.

    OUTCOME MEASURES: Consenting participants from the MELoR study were asked the question 'Have you fallen down in the past 12 months?' during their computer-assisted home-based interviews. Logistic regression analyses were conducted to compare the prevalence of falls among various ethnic groups.

    RESULTS: The overall estimated prevalence of falls for individuals aged 55 years and over adjusted to the population of Kuala Lumpur was 18.9%. The estimated prevalence of falls for the three ethnic populations of Malays, Chinese and Indian aged 55 years and over was 16.2%, 19.4% and 23.8%, respectively. Following adjustment for ethnic discrepancies in age, gender, marital status and education attainment, the Indian ethnicity remained an independent predictor of falls in our population (relative risk=1.45, 95% CI 1.08 to 1.85).

    CONCLUSION: The prevalence of falls in this study is comparable to other previous Asian studies, but appears lower than Western studies. The predisposition of the Indian ethnic group to falls has not been previously reported. Further studies may be needed to elucidate the causes for the ethnic differences in fall prevalence.

  18. Status epilepticus in Auckland, New Zealand: Incidence, etiology, and outcomes
    Bergin PS, Brockington A, Jayabal J, Scott S, Litchfield R, Roberts L, et al.
    Epilepsia, 2019 08;60(8):1552-1564.
    PMID: 31260104 DOI: 10.1111/epi.16277
    OBJECTIVE: To determine the incidence, etiology, and outcome of status epilepticus (SE) in Auckland, New Zealand, using the latest International League Against Epilepsy (ILAE) SE semiological classification.

    METHODS: We prospectively identified patients presenting to the public or major private hospitals in Auckland (population = 1.61 million) between April 6, 2015 and April 5, 2016 with a seizure lasting 10 minutes or longer, with retrospective review to confirm completeness of data capture. Information was recorded in the EpiNet database.

    RESULTS: A total of 477 episodes of SE occurred in 367 patients. Fifty-one percent of patients were aged <15 years. SE with prominent motor symptoms comprised 81% of episodes (387/477). Eighty-four episodes (18%) were nonconvulsive SE. Four hundred fifty episodes occurred in 345 patients who were resident in Auckland. The age-adjusted incidence of 10-minute SE episodes and patients was 29.25 (95% confidence interval [CI] = 27.34-31.27) and 22.22 (95% CI = 20.57-23.99)/100 000/year, respectively. SE lasted 30 minutes or longer in 250 (56%) episodes; age-adjusted incidence was 15.95 (95% CI = 14.56-17.45) SE episodes/100 000/year and 12.92 (95% CI = 11.67-14.27) patients/100 000/year. Age-adjusted incidence (10-minute SE) was 25.54 (95% CI = 23.06-28.24) patients/100 000/year for males and 19.07 (95% CI = 16.91-21.46) patients/100 000/year for females. The age-adjusted incidence of 10-minute SE was higher in Māori (29.31 [95% CI = 23.52-37.14]/100 000/year) and Pacific Islanders (26.55 [95% CI = 22.05-31.99]/100 000/year) than in patients of European (19.13 [95% CI = 17.09-21.37]/100 000/year) or Asian/other descent (17.76 [95% CI = 14.73-21.38]/100 000/year). Seventeen of 367 patients in the study died within 30 days of the episode of SE; 30-day mortality was 4.6%.

    SIGNIFICANCE: In this population-based study, incidence and mortality of SE in Auckland lie in the lower range when compared to North America and Europe. For pragmatic reasons, we only included convulsive SE if episodes lasted 10 minutes or longer, although the 2015 ILAE SE classification was otherwise practical and easy to use.

  19. Fulltext Epidemiology of Male Sexual Dysfunction in Asian and European Regions: A Systematic Review
    Irfan M, Hussain NHN, Noor NM, Mohamed M, Sidi H, Ismail SB
    Am J Mens Health, 2020 7 7;14(4):1557988320937200.
    PMID: 32623948 DOI: 10.1177/1557988320937200
    Male sexual dysfunctions (MSDs) often remain undiagnosed and untreated in Asia compared to Europe due to conservative cultural and religious beliefs, socioeconomic conditions, and lack of awareness. There is a tendency for the use of traditional medicines and noncompliance with and reduced access to modern healthcare. The present systematic review compared the incidence and factors of MSD in European and Asian populations. English language population/community-based original articles on MSDs published in MEDLINE from 2008 to 2018 were retrieved. A total of 5392 studies were retrieved, of which 50 (25 Asian and 25 European) were finally included in this review. The prevalence of erectile dysfunction (ED) (0%-95.0% vs. 0.9%-88.8%), low satisfaction (3.2%-37.6% vs. 4.1%-28.3%), and hypoactive sexual desire disorder (HSDD) (0.7%-81.4 vs. 0%-65.5%) was higher in Asian than in European men, whereas the prevalence of anorgasmia (0.4% vs. 3%-65%) was lower in Asian than in European men. Age was an independent positive factor of MSD. In European men over 60 years old, the prevalence of premature ejaculation (PE) decreased. The prevalence of MSD was higher in questionnaires than in interviews. The significant factors were age, single status, low socioeconomic status, poor general health, less physical activity, cardiovascular diseases, diabetes, obesity, lower urinary tract symptoms, prostatitis, anxiety, depression and alcohol, tobacco, and drug use. The prevalence of MSD differed slightly in Asian and European men. There is a need to conduct large studies on the various Asian populations for the effective management of MSD.

  20. Reliability and validity of the National Institutes of Health: Chronic Prostatitis Symptom Index in a Malaysian population
    Cheah PY, Liong ML, Yuen KH, Lee S, Yang JR, Teh CL, et al.
    World J Urol, 2006 Feb;24(1):79-87.
    PMID: 16465553 DOI: 10.1007/s00345-005-0037-z
    The objective of the study is to determine the short- and long-term utility of the Chinese, Malay and English versions of the National Institutes of Health--Chronic Prostatitis Symptom Index (NIH-CPSI) in our ethnically diverse population. The NIH-CPSI was translated into Chinese and Malay, and then verified by back translation into English. Subjects included 100 new chronic prostatitis/chronic pelvic pain (CP/CPPS) patients, 71 new benign prostatic hyperplasia patients and 97 healthy individuals. Reliability was evaluated with test-retest reproducibility (TR) by calculating intraclass correlation coefficients (ICC). Internal consistency was evaluated by calculating Cronbach's alpha (alpha). Validity assessments included discriminant and construct validity. (Presented in the order of Chinese, Malay then English). ICC values for short-term (1 week) TR were 0.90, 0.80 and 0.89, while ICC values for long-term (14 weeks) TR were 0.54, 0.61 and 0.61. Cronbach's alpha values were 0.63, 0.62 and 0.57. The NIH-CPSI total score discriminated CP/CPPS patients (P<0.001) from the control groups with receiver operating curve values of 0.95, 0.98 and 0.94, respectively. Construct validity, reflected by the correlation coefficient values between the International Prostate Symptom Score and the NIH-CPSI of CP/CPPS patients were 0.72, 0.49 and 0.63 (all P<0.05). The Chinese, Malay and English versions of the NIH-CPSI each proved effective in our population. Short-term TR and discriminant validity were excellent for all three versions. However, long-term TR was only moderate, which might reflect variation in patients' perceptions of symptoms over time.
