  1. Fulltext Cross-cultural comparison of maternal sleep
    Mindell JA, Sadeh A, Kwon R, Goh DY
    Sleep, 2013 Nov;36(11):1699-706.
    PMID: 24179304 DOI: 10.5665/sleep.3132
    BACKGROUND:
    To characterize cross-cultural sleep patterns and sleep problems in a large sample of mothers of children (ages birth to 6 years) in multiple predominantly Asian and predominantly Caucasian countries.

    METHODS:
    Mothers of 10,085 young children (predominantly Asian countries/regions: China, Hong Kong, India, Korea, Japan, Malaysia, Philippines, Singapore, Thailand; predominantly Caucasian countries: Australia, Canada, New Zealand, United Kingdom, United States) completed an internet-based expanded version of the Pittsburgh Sleep Quality Index.

    RESULTS:
    Mothers in predominantly Asian countries/regions had later bedtimes, decreased number and duration of night wakings, more nighttime sleep, and more total sleep than mothers from predominantly Caucasian countries, P < 0.001. More than half (54.7%) of mothers reported having poor sleep, ranging from 50.9% of mothers in Malaysia to 77.8% of mothers in Japan. Sleep disturbance symptoms were quite common, especially symptoms related to insomnia, and were more likely to be reported by mothers in predominantly Caucasian countries. However, psychosocial factors, including having children of a younger age, being unemployed, and having a lower education level were the best predictors of poor sleep, whereas culture was not a significant predictor.

    CONCLUSIONS:
    Overall, mothers in predominantly Asian countries/regions reported later bedtimes but sleeping better and longer than mothers from predominantly Caucasian countries, which is dissimilar to cross-cultural findings of young children. Psychosocial factors were found to be the best predictors of poor sleep, irrespective of culture. Further studies are needed to understand the impact of these findings.

    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

  5. Cross-cultural similarities and differences in the experience of awe
    Razavi P, Zhang JW, Hekiert D, Yoo SH, Howell RT

    PMID: 27632153
    Current research on awe is limited to Western cultures. Thus, whether the measurement, frequency, and consequences of awe will replicate across non-Western cultures remains unanswered. To address this gap, we validated the dispositional awe scale (Shiota, Keltner, & John, 2006) in 4 countries (United States, Iran, Malaysia, and Poland; N = 1,173) with extensive variations in cultural values (i.e., power distance) and personality profiles (i.e., extraversion and openness). Multigroup factor analyses demonstrated that, across all cultures, a 3-factor model that treats awe, amusement, and pride as 3 unique emotions is superior to a single-factor model that clusters all 3 emotions together. Structurally, the scales of awe, amusement and pride were invariant across all countries. Furthermore, we found significant country-level differences in dispositional awe, with the largest discrepancy between the United States and Iran (d = 0.79); these differences are not likely due to cultural response biases. Results are discussed in terms of possible explanations for country-level differences and suggestions for future research. (PsycINFO Database Record

    Schools and colleges of pharmacy in the United States increasingly interact with those in Asian countries for various purposes such as education and research. For both those visiting and those hosting, it is important to understand and respect the culture of the other's country to enrich these interactions. This paper, the second of two manuscripts on Asian countries, focuses on India, Indonesia, Malaysia, Philippines, and Vietnam. For each country, the following information is provided: general introduction, health care system, pharmacy practice, and pharmacy education, stereotypes and misconceptions, recommendations for US-based health care professionals, faculty members, and students who visit these Asian countries, and recommendations for them to host visitors from these Asian countries. The aim of this paper is to assist US health care professionals, faculty members, and students in initiating and promoting a culturally sensitive engagement.

  7. Cultural considerations in forgoing enteral feeding: A comparison between the Hong Kong Chinese, North American, and Malaysian Islamic patients with advanced dementia at the end-of-life
    Ngan OMY, Bergstresser SM, Sanip S, Emdadul Haque ATM, Chan HYL, Au DKS
    Dev World Bioeth, 2020 06;20(2):105-114.
    PMID: 31241234 DOI: 10.1111/dewb.12239
    Cultural competence, a clinical skill to recognise patients' cultural and religious beliefs, is an integral element in patient-centred medical practice. In the area of death and dying, physicians' understanding of patients' and families' values is essential for the delivery of culturally appropriate care. Dementia is a neurodegenerative condition marked by the decline of cognitive functions. When the condition progresses and deteriorates, patients with advanced dementia often have eating and swallowing problems and are at high risk of developing malnutrition. Enteral tube feeding is a conventional means of providing artificial nutrition and hydration to meet nutritional needs, but its benefits to the frail population are limitedly shown in the clinical evidence. Forgoing tube feeding is ethically challenging when patients are mentally incompetent and in the absence of an advance directive. Unlike some developed countries, like the United States of America, death and dying is a sensitive issue or even a taboo in some cultures in developing countries that forgoing enteral tube feeding is clinically and ethically challenging, such as China and Malaysia. This article in three parts 1) discusses the clinical and ethical issues related to forgoing tube feeding among patients with advanced dementia, 2) describes how Hong Kong Chinese, North American, and Malaysian Islamic cultures respond differently in the decision-making patterns of forgoing tube feeding for patients with advanced dementia, and 3) reiterates the clinical implications of cultural competence in end-of-life care.

  8. Culture and alexithymia: mean levels, correlates, and the role of parental socialization of emotions
    Le HN, Berenbaum H, Raghavan C
    Emotion, 2002 Dec;2(4):341-60.
    PMID: 12899369
    Two studies examined the relationship between culture and alexithymia. In Study 1, mean levels and correlates of alexithymia were examined in 3 cultures: European American (EA), Asian American (AA), and Malaysian college students. Both Asian groups had higher alexithymia levels than the EA group. Somatization was more strongly associated with alexithymia in the Asian groups than in the EA group. Mood and life satisfaction were associated with alexithymia in similar ways across groups. In Study 2, the relations among culture, gender, retrospective reports of parental socialization of emotions, and alexithymia were examined among EA and AA college students. Cultural and gender differences were found in alexithymia and emotion socialization levels. Most important, parental emotion socialization mediated the relations among culture, gender, and alexithymia.

  9. Fulltext Culture, cross-role consistency, and adjustment: testing trait and cultural psychology perspectives
    Church AT, Anderson-Harumi CA, del Prado AM, Curtis GJ, Tanaka-Matsumi J, Valdez Medina JL, et al.
    J Pers Soc Psychol, 2008 Sep;95(3):739-55.
    PMID: 18729706 DOI: 10.1037/0022-3514.95.3.739
    Trait and cultural psychology perspectives on cross-role consistency and its relation to adjustment were examined in 2 individualistic cultures, the United States (N=231) and Australia (N=195), and 4 collectivistic cultures, Mexico (N=199), the Philippines (N=195), Malaysia (N=217), and Japan (N=180). Cross-role consistency in trait ratings was evident in all cultures, supporting trait perspectives. Cultural comparisons of mean consistency provided support for cultural psychology perspectives as applied to East Asian cultures (i.e., Japan) but not collectivistic cultures more generally. Some but not all of the hypothesized predictors of consistency were supported across cultures. Cross-role consistency predicted aspects of adjustment in all cultures, but prediction was most reliable in the U.S. sample and weakest in the Japanese sample. Alternative constructs proposed by cultural psychologists--personality coherence, social appraisal, and relationship harmony--predicted adjustment in all cultures but were not, as hypothesized, better predictors of adjustment in collectivistic cultures than in individualistic cultures.

  11. Current and Future Potential Impact of COVID-19 on Kratom (Mitragyna speciosa Korth.) Supply and Use
    Singh D, Brown PN, Cinosi E, Corazza O, Henningfield JE, Garcia-Romeu A, et al.
    Front Psychiatry, 2020;11:574483.
    PMID: 33324252 DOI: 10.3389/fpsyt.2020.574483
    Kratom (Mitragyna speciosa Korth., Rubiaceae) is native to and has traditional use in Southeast Asia. The number of kratom users outside of Southeast Asia has increased significantly in recent decades with use spreading to the Unites States (US) and Europe. Because of its reputed opioid-like psychoactive effects at higher doses, kratom has been regulated in several countries and is subject to an import ban by the US Food and Drug Administration. Nonetheless, in the US it is estimated that 10-15 million people consume kratom primarily for the self-treatment of pain, psychiatric disorders, to mitigate withdrawal from or dependence on opioids, and to self-treat opioid use disorder or other substance use disorders (SUDs). Due to the global COVID-19 pandemic, a shortage in the supply of kratom products may place unexpected burdens on kratom users, potentially influencing some who use kratom for SUD self-treatment to regress to harmful drug use, hence increasing the likelihood of adverse outcomes, including overdose. Inadequate treatment, treatment barriers, and increases in the sales of adulterated kratom products on the internet or in convenience stores could exacerbate circumstances further. Although there are currently no verified indications of kratom scarcity, researchers and clinicians should be aware of and remain vigilant to this unanticipated possibility.

  12. Current intervention strategies for the microbial safety of sprouts
    Sikin AM, Zoellner C, Rizvi SS
    J Food Prot, 2013 Dec;76(12):2099-123.
    PMID: 24290689 DOI: 10.4315/0362-028X.JFP-12-437
    Sprouts have gained popularity worldwide due to their nutritional values and health benefits. The fact that their consumption has been associated with numerous outbreaks of foodborne illness threatens the $250 million market that this industry has established in the United States. Therefore, sprout manufacturers have utilized the U.S. Food and Drug Administration recommended application of 20,000 ppm of calcium hypochlorite solution to seeds before germination as a preventative method. Concentrations of up to 200 ppm of chlorine wash are also commonly used on sprouts. However, chlorine-based treatment achieves on average only 1- to 3-log reductions in bacteria and is associated with negative health and environmental issues. The search for alternative strategies has been widespread, involving chemical, biological, physical, and hurdle processes that can achieve up to 7-log reductions in bacteria in some cases. The compilation here of the current scientific data related to these techniques is used to compare their efficacy for ensuring the microbial safety of sprouts and their practicality for commercial producers. Of specific importance for alternative seed and sprout treatments is maintaining the industry-accepted germination rate of 95% and the sensorial attributes of the final product. This review provides an evaluation of suggested decontamination technologies for seeds and sprouts before, during, and after germination and concludes that thermal inactivation of seeds and irradiation of sprouts are the most practical stand-alone microbial safety interventions for sprout production.

  13. Current status of pharmacovigilance regulatory structures, processes, and outcomes in the Asia-Pacific region: Survey results from 15 countries
    Shin JY, Shin E, Jeong HE, Kim JH, Lee EK
    Pharmacoepidemiol Drug Saf, 2019 03;28(3):362-369.
    PMID: 30648304 DOI: 10.1002/pds.4717
    PURPOSE: Regulatory discrepancies may exist in pharmacovigilance (PV) structure, process, and outcome status worldwide. Our study's objective was to survey the current status of PV in each regulatory body in the Asia-Pacific Economic Cooperation (APEC) region.

    METHODS: A modified questionnaire was sent to the PV team heads of 21 PV agencies based in the APEC countries, between June 28 and September 12, 2017, to gather information on the structure, process, and outcome of PV status in these countries.

    RESULTS: Of the 21 APEC countries, 15 responded. We found harmonized laws and regulations for general PV and risk management systems. However, variations were found in PV structure: for example, 11 out of 15 countries had national regulatory representatives responsible for PV in pharmaceutical companies, while four did not. For PV process, discrepancies were also found in the source type of adverse drug reaction (ADR) reports and reporting of medication errors and therapeutic ineffectiveness in cumulative ADR reports. With respect to PV outcomes, among countries that performed active surveillance, the United States of America was more active, with hundreds of projects including additional pharmacoepidemiological studies etc. Among the nine countries that responded, Japan had the greatest number of product label changes followed by Taiwan, Malaysia, and Korea.

    CONCLUSION: We have identified substantial variations in the structures, processes, and outcomes of PV status among the countries of the APEC region. Therefore, efforts to reduce variations in the PV administration and regulation are warranted for harmonization of PV within the APEC region.

  14. Cytochrome P450 genotype-guided drug therapies: An update on current states
    Dong AN, Tan BH, Pan Y, Ong CE
    Clin Exp Pharmacol Physiol, 2018 10;45(10):991-1001.
    PMID: 29858511 DOI: 10.1111/1440-1681.12978
    Over the past 2 decades, knowledge of the role and clinical value of pharmacogenetic markers has expanded so that individualized pre-emptive therapy based on genetic background of patients could be within reach for clinical implementation. This is evidenced from the frequent updating of drug labels that incorporates pharmacogenetic information (where compelling data become available) by the regulatory agencies (such as the US FDA), and the periodical publication of guidelines of specific therapeutic recommendations based on the results of pharmacogenetic tests by the pharmacogenetics working groups or consortiums of professional bodies. Clinical relevance of the cytochrome P450 (CYP) polymorphism related to dose, effectiveness and/or toxicity of key drugs are presented in this review, including that of warfarin, clopidogrel, tricyclic antidepressants, and proton pump inhibitors. Prospect for routine clinical application of CYP genotyping before prescribing drugs is still currently unclear due to challenges and barriers associated with availability of well-defined and validated pharmacogenetic studies, the interpretation, result reporting and potential error of genotype testing, involvement of non-genetic factors, and other patient's demographic and disease conditions. Further studies to provide additional supporting clinical data and acceleration of pharmacogenetic testing standards and techniques should help improve the evidence base needed for clinical utility and hence move the implementation of genotype-guided therapy in clinical practice a step closer to reality.

    Malaysian construction firms have increasingly gained investment opportunities in foreign countries pushed by the competitive and saturated domestic market. However, the entry location decision involves complex factors to be considered by these firms prior to their international operations. Currently, based on a secondary data obtained from the Construction Industry Development Board (CIDB) Malaysia, there are twelve (12) firms that are actively operating in international markets. The main objective of this preliminary study is to develop an entry location assessment criteria (ELAC) model based on the performance of Malaysian construction firms in international markets. The ELAC formula was derived through a development of taxonomy criteria from previous studies. The construction firms’ performance was analyzed and ranked using a weightage score characterized under three (3) dimensions of country with the taxonomy criteria. First dimension involves entry location decision to countries in ASEAN, Non-ASEAN and both regions, while the second dimension involves entry location decision to ASEAN, Asia, Africa, United States of America and Europe while the third dimension involves entry location decision to countries categorized as Developing Countries (DLC); Least Developed Country (LDC); Newly Industrialized Countries (NIC); Developed Countries (DC); and Highly Developed Countries (HDC). The ELAC score shows that three (3) construction firms which are, Sapura Energy Berhad (66%), Gamuda Berhad (53%) and Sime Darby Berhad (50%) have sustained international operations in various locations by obtaining an ELAC score of more than 50% by venturing to ASEAN countries, developing countries and developed countries. Even though his study is limited to Malaysian construction firms, it provides significant information and contributes to the current knowledge in international market expansion. This ELAC model is useful especially for construction firms that are just beginning to explore foreign business opportunities or for the global players that are expanding geographically to new international markets.

    The paper focused on the examination and testing of local exhaust ventilation (LEV) systems at one of Electrical Company to check the transport velocity whether it meet the recommended American Governmental Industrial Hygienist (ACGIH) Standard. The industrial hygiene approaches, AREC (Anticipating, Recognize, Evaluate and Control) were adopted in this study. This is to ensure that the LEV system installed has the optimum efficiency to extract out the contaminants from the workstation. Objective of this study is to make comparison with previous and current monitoring data. The efficiency and the other parameter measured will be the main source to analyze for the particular applications. The differential of data was discussed and several recommendations are proposed to make sure the LEV system performance is excellent.

    The Transient Electro-Magnetic (TEM) geophysical technique was deployed to map and characterized the subsurface of Pahang River Basin along the East Coast Peninsula Malaysia. The data aimed at differentiating between the massive zones and the weak zones within the region, to also assess and differentiate the subsurface structures and comes up with recommendations for policy decision, formulation and plans on the flooding impact, surface water and groundwater managements, in addition to other environmental related issues ravaging the area. The data presented in this paper, showed the properties of the subsurface rocks underlain the region as beneficial to the Agriculturists; Climatologists; Engineers; Environmentalists; Geoscientists, Hydrologists and Policy formulation officers. The TEM data collection utilized a 100 m x 100 m single loop coil for both the Transmitter (Tx) loop and the Receiver (Rx) loop to produce a total surface area coverage of 10,000 m2 per survey line along a single profile. The total area covered in the data extended across an average area of 30 km x 40 km in parts of Maran, Temerloh and Jerantut districts, within the State of Pahang, East Coast, Peninsula Malaysia. The conductivity data recorded varied from -20 mS/m to about 440 mS/m at a maximum depth of about 375 m. On the other hand, the resistivity data recorded varied from 0 Oh-m to about 1000 Oh-m. The information derived from the data are intended for potential abstraction by the Malaysian Groundwater Management Board; the Department of Mineral and Geoscience; Department of Irrigation and Drainage; the Pahang State Water Board, and the Department of Agriculture.

    Kajian ini bertujuan untuk mendapatkan data normatif timpanometri di kalangan kanak-kanak Melayu prasekolah dan membandingkannya menurut jantina. Ini kerana faktor bukan patologi seperti umur, jantina dan bangsa mempengaruhi data normatif timpanometri. Sehubungan itu, garis panduan saringan telinga tengah oleh American Speech and Hearing Association (ASHA) yang menggunakan data normatif timpanometri kanak-kanak Kaukasian mungkin tidak sesuai untuk populasi kanak-kanak Melayu. Parameter timpanometri yang diukur ialah puncak statik admitan akustik dikompensasi (puncak Ytm), isipadu salur telinga luar (Vea) dan kelebaran timpanogram (TW). Seramai 161 orang kanak-kanak Melayu (80 orang kanak-kanak lelaki dan 81 orang kanak-kanak perempuan) berumur antara 4 hingga 6 tahun terlibat di dalam kajian ini. Bagaimanapun, hanya seramai 45 orang kanak-kanak lelaki dan 46 orang kanak-kanak perempuan (163 dari keseluruhan 182 telinga) memenuhi kriteria inklusi iaitu lulus pemeriksaan otoskopi dan saringan pendengaran serta menunjukkan refleks akustik ipsilateral pada 1000 Hz. Ujian ANOVA Campuran dua-hala untuk membandingkan min parameter timpanometri kanak-kanak lelaki dan perempuan menunjukkan tiada perbezaan yang signifikan; min puncak Ytm (p > 0.05), min Vea (p > 0.05), dan min TW (p > 0.05). Oleh itu, data kedua-dua kumpulan ini digabungkan. Secara keseluruhan, nilai min puncak Ytm ialah 0.55 ± 0.28mmhos, min Vea ialah 0.90 ± 0.39 cm3, dan min TW ialah 104.68 ± 32.08 daPa. Julat normal persentil ke-90 bagi puncak Ytm ialah antara 0.27 hingga 1.18 mmhos, Vea antara 0.45 hingga 1.65 cm3 dan TW antara 59.60 hingga 149.80 daPa. Hasil kajian mencadangkan data normatif timpanometri ini sesuai digunakan ke atas kanak-kanak Melayu prasekolah namun ianya tidak perlu dibezakan mengikut jantina. Sekiranya setiap satu nilai TW > 200 daPa dan Vea > 1.0 cm3 oleh ASHA diaplikasi ke atas kanak-kanak Melayu prasekolah, maka masing-masing akan menyebabkan kadar rujukan yang rendah dan kadar rujukan yang berlebihan.

    Coal combustion by-products (CCPs) (i.e. fly (FA) and bottom (BA) ashes) generated by power plants contain heavy metals. This research presents leaching properties of coal ashes (FA and BA) collected from Jimah coal-fired power station, Port Dickson, Negeri Sembilan using USEPA standard methods namely toxicity characteristic leaching procedure (TCLP), and synthetic precipitation leaching procedure (SPLP). Heavy metals like lead (Pb), zinc (Zn), copper (Cu) and arsenic (As) were quantified using atomic absorption spectrometer (AAS). The leached of heavy metals fluxes were Cu < Zn < Pb < As. As leached the most whilst indicating of possible contamination from As. Overall, the ranges of leached concentration were adhered to permissible limits of hazardous waste criteria for metal (Pb and As) and industrial effluent (Zn and Cu). The presented data has potential reuse as reference for the coal ash concrete mixed design application in construction industries.

    Perak River basin is in Perak state of Peninsular Malaysia. In this research, the river stretch serves as water intake for domestic, agricultural and industrial purposes in Perak Tengah, Hilir Perak and Manjung regions. It is located in mixed use area whilst exposing the river to anthropogenic elements. The sampling locations were conducted at selected points of Perak River namely Tanjung Belanja Bridge (TBB), Water Treatment Plant Parit (WTPP), Parit Town discharge (PTD), Water Treatment Plant Senin (WTPS) and Water Treatment Plant Kepayang (WTPK). The existence of aromatic hydrocarbons in freshwater samples was pre-assessed via qualification analysis; specific ultraviolet absorbance (SUVA254) method at 254 nm of wavelength. The SUVA dataset were 48.38 L/mg-m (TBB), 50.54 L/mg-m (WTPP), 8.05 L/mg-m (PTD), 85.75 L/mg-m (WTPS) and 217.39 L/mg-m (WTPK). The SUVA254 values of fresh water at the river basin have exceeded the water quality standards value equivalent to 2.0 L/mg-m permitted by the Environmental Protection Agency of United States. The exceeding values were an indication of a large portion of aromatic compounds in the water. Qualification analyses evident the existence of water pollutants at treacherous concentrations for public health in freshwater samples of Perak River basin. Thus, this research has presented important findings towards further research and countermeasure for a better alternative of water treatment in Malaysia.
