Attitudes toward epilepsy in East Malaysia using the Public Attitudes Toward Epilepsy (PATE) scale

Chia ZJ, Lim KS, Fong SL, Sim RS, Rajahram GS, Narayanan V, et al.

Epilepsy Behav, 2020 09;110:107158.
PMID: 32512367 DOI: 10.1016/j.yebeh.2020.107158

BACKGROUND: Epilepsy stigma is an important issue affecting people with epilepsy (PWE) in various social aspects of life. Most studies on stigma were among the metropolitan population but rarely on indigenous people. Hence, this study aimed to understand the attitudes toward epilepsy of the East Malaysians, comparing with the West Malaysians previously reported.
METHOD: This study was performed among the indigenous people in Kuching and Sibu (Sarawak) and Kota Kinabalu (Sabah) using the Public Attitudes Toward Epilepsy (PATE) scale. A higher score indicates poorer attitude.
RESULT: A total of 360 respondents (41.7% Kadazan-Dusun, 30.6% Bidayuh, and 24.7% Iban) aged 34.6 ± 12.6 years completed the questionnaire. They were predominantly females and had lower education level and income compared with the West Malaysians. The Sabah population had significantly lower mean scores (better attitudes) than those in Sarawak, in both personal and general domains (p

An epidemiologic study of osteogenic sarcoma in Malaysia. Incidence in urban as compared with rural environments and in each of three separate racial groups, 1969-1972

Silva JF, Subramanian N

Clin Orthop Relat Res, 1975 Nov-Dec;?(113):119-27.
PMID: 1059509

To explore the possibility that environmental and/or genetic factors may yield clues to the etiology of osteogenic sarcoma, an epidemiologic retrospective study of all cases of osteogenic sarcoma in a country with clear geographic and racial variables (Malaysia) was conducted covering a 4-year period. Sixty-eight cases were identified (+85% of the predicted total). The incidence (cases per 100,000 population per year) was 0.11 in Malay, 0.23 in the Chinese, and 0.23 in the Indian. The urban versus rural incidence in the Malay was 0.22 versus 0.09, and in the Chinese 0.31 versus 0.18. The Indian population was too small when dividied into urban and rural segments to be significant.

Family type and fertility: a review of literature

Kim O-k, Shah IH

Kajok Kyehoek Nonjip, 1979 Nov;6:142-58.
PMID: 12178433

PIP: It is generally believed that extended families encourage high fertility, but a review of the theoretical discussions and empirical research examining the relationship between family type and fertility fails to show any support for the customary belief. Nuclear families consist of husband, wife, and their immediate children. The extended family is broadly defined as any group of related persons living together which includes but is larger than the nuclear family. The main theoretical discussions of extended family and fertility are by Davis (1957); Davis and Blake (1956); Lorimer (1954); and Goode (1963; 1964). In the patrilocal extended family, the wife wants to have offspring as early as possible to strengthen the family line and her own status in the household. In a truly joint household the authority of the elders continues after marriage; the reproductive behavior of a couple is subject to their influence. Less intimate or less intense interspousal communication precludes the possibility of discussion on fertility-related problems and family planning. Younger age at marriage and lack of privacy contributes to higher fertility. According to Goode extended family behavior is characterized by more rules for behavior, while nuclear families emphasize the conjugal bond. Since most affinal and consanguineal kin are excluded from day-to-day decisions in the nuclear family there are weaker reciprocal controls.

Characterization of genetic sequence variation of 58 STR loci in four major population groups

Novroski NMM, King JL, Churchill JD, Seah LH, Budowle B

Forensic Sci Int Genet, 2016 11;25:214-226.
PMID: 27697609 DOI: 10.1016/j.fsigen.2016.09.007

Massively parallel sequencing (MPS) can identify sequence variation within short tandem repeat (STR) alleles as well as their nominal allele lengths that traditionally have been obtained by capillary electrophoresis. Using the MiSeq FGx Forensic Genomics System (Illumina), STRait Razor, and in-house excel workbooks, genetic variation was characterized within STR repeat and flanking regions of 27 autosomal, 7 X-chromosome and 24 Y-chromosome STR markers in 777 unrelated individuals from four population groups. Seven hundred and forty six autosomal, 227 X-chromosome, and 324 Y-chromosome STR alleles were identified by sequence compared with 357 autosomal, 107 X-chromosome, and 189 Y-chromosome STR alleles that were identified by length. Within the observed sequence variation, 227 autosomal, 156 X-chromosome, and 112 Y-chromosome novel alleles were identified and described. One hundred and seventy six autosomal, 123 X-chromosome, and 93 Y-chromosome sequence variants resided within STR repeat regions, and 86 autosomal, 39 X-chromosome, and 20 Y-chromosome variants were located in STR flanking regions. Three markers, D18S51, DXS10135, and DYS385a-b had 1, 4, and 1 alleles, respectively, which contained both a novel repeat region variant and a flanking sequence variant in the same nucleotide sequence. There were 50 markers that demonstrated a relative increase in diversity with the variant sequence alleles compared with those of traditional nominal length alleles. These population data illustrate the genetic variation that exists in the commonly used STR markers in the selected population samples and provide allele frequencies for statistical calculations related to STR profiling with MPS data.

Comparative genetic stock structure in three species of commercially exploited Indo-Malay Carangidae (Teleosteii, Perciformes)

Mat Jaafar TNA, Taylor MI, Mohd Nor SA, Bruyn M, Carvalho GR

J Fish Biol, 2020 Feb;96(2):337-349.
PMID: 31721192 DOI: 10.1111/jfb.14202

We examine genetic structuring in three commercially important species of the teleost family Carangidae from Malaysian waters: yellowtail scad Atule mate, bigeye scad Selar crumenophthalmus and yellowstripe scad Selaroides leptolepis, from the Indo-Malay Archipelago. In view of their distribution across contrasting habitats, we tested the hypothesis that pelagic species display less genetic divergence compared with demersal species, due to their potential to undertake long-distance migrations in oceanic waters. To evaluate population genetic structure, we sequenced two mitochondrial (mt)DNA [650 bp of cytochrome oxidase I (coI), 450 bp of control region (CR)] and one nuclear gene (910 bp of rag1) in each species. One hundred and eighty samples from four geographical regions within the Indo-Malay Archipelago including a population of yellowtail from Kuwait were examined. Findings revealed that the extent of genetic structuring among populations in the semi-pelagic and pelagic, yellowtail and bigeye were lower than demersal yellowstripe, consistent with the hypothesis that pelagic species display less genetic divergence compared with demersal species. The yellowtail phylogeny identified three distinct clades with bootstrap values of 86%-99% in mtDNA and 63%-67% in rag1. However, in bigeye, three clades were also observed from mtDNA data while only one clade was identified in rag1 dataset. In yellowstripe, the mtDNA tree was split into three closely related clades and two clades in rag1 tree with bootstraps value of 73%-99% and 56% respectively. However, no geographic structure appears in both mtDNA and rag1 datasets. Hierarchical molecular variance analysis (AMOVA), pair wise FST comparisons and the nearest-neighbour statistic (Snn ) showed significant genetic differences among Kuwait and Indo-Malay yellowtail. Within the Indo-Malay Archipelago itself, two distinct mitochondrial lineages were detected in yellowtail suggesting potential cryptic species. Findings suggests varying degrees of genetic structuring, key information relevant to management of exploited stocks, though more rapidly evolving genetic markers should be used in future to better delimit the nature and dynamics of putative stock boundaries.

Fulltext Racial/ancestral diversity in 174 toxicity-related radiogenomic studies: A systematic review

Zuber SH, Yahya N

J Cancer Res Ther, 2021 6 15;17(2):477-483.
PMID: 34121695 DOI: 10.4103/jcrt.JCRT_896_18

Purpose: This study systematically reviews the distribution of racial/ancestral features and their inclusion as covariates in genetic-toxicity association studies following radiation therapy.
Materials and Methods: Original research studies associating genetic features and normal tissue complications following radiation therapy were identified from PubMed. The distribution of radiogenomic studies was determined by mining the statement of country of origin and racial/ancestrial distribution and the inclusion in analyses. Descriptive analyses were performed to determine the distribution of studies across races/ancestries, countries, and continents and the inclusion in analyses.
Results: Among 174 studies, only 23 with a population of more one race/ancestry which were predominantly conducted in the United States. Across the continents, most studies were performed in Europe (77 studies averaging at 30.6 patients/million population [pt/mil]), North America (46 studies, 20.8 pt/mil), Asia (46 studies, 2.4 pt/mil), South America (3 studies, 0.4 pt/mil), Oceania (2 studies, 2.1 pt/mil), and none from Africa. All 23 studies with more than one race/ancestry considered race/ancestry as a covariate, and three studies showed race/ancestry to be significantly associated with endpoints.
Conclusion: Most toxicity-related radiogenomic studies involved a single race/ancestry. Individual Participant Data meta-analyses or multinational studies need to be encouraged.

Teenage births on the decline

Peng TN

Malays J Reprod Health, 1986 Dec;4(2):91-6.
PMID: 12314888

PIP: In Peninsular Malaysia, while the female population aged 15-19 years registered a growth of some 240,000 persons between 1966-1984, the number of births occurring to teenage mothers has decreased by 15,176 from 33,348 to 18,172 during the same period. In 1966, teenage births constituted some 10.8% of the total births but has declined to 4.7% by 1984. A breakdown of the 1984 data by detailed age groups shows that only 0.9% of the teenage births had actually occurred among those below 15 years of age. The declining trend in teenage births, particularly the higher order births among the very young mothers, augurs well for the improvement in family welfare. However, in order to safeguard the health and welfare of mothers and children, concerted efforts should continue to be undertaken to integrate population, family health and family life education into the school curriculum.

PMID: 12320336

PIP: Data from 297 interviews among married patients attending prenatal clinics in Malaysia in 1993 are used to determine the number, spacing, and timing of pregnancies. Only live born children are included. Findings indicate that 92.2% of women were 18-35 years old, 4.2% were under 18 years of age, and 3.6% were over 35 years old. 86.2% had 4 or fewer children and 13.8% had 4 or more children. 69.7% spaced children 2 or more years apart and 30.3% had birth spacing of under 2 years. Over 90% of women had their pregnancies during the ages of 18 and 35 years.

Population and performance analyses of four major populations with Illumina's FGx Forensic Genomics System

Churchill JD, Novroski NMM, King JL, Seah LH, Budowle B

Forensic Sci Int Genet, 2017 09;30:81-92.
PMID: 28651097 DOI: 10.1016/j.fsigen.2017.06.004

The MiSeq FGx Forensic Genomics System (Illumina) enables amplification and massively parallel sequencing of 59 STRs, 94 identity informative SNPs, 54 ancestry informative SNPs, and 24 phenotypic informative SNPs. Allele frequency and population statistics data were generated for the 172 SNP loci included in this panel on four major population groups (Chinese, African Americans, US Caucasians, and Southwest Hispanics). Single-locus and combined random match probability values were generated for the identity informative SNPs. The average combined STR and identity informative SNP random match probabilities (assuming independence) across all four populations were 1.75E-67 and 2.30E-71 with length-based and sequence-based STR alleles, respectively. Ancestry and phenotype predictions were obtained using the ForenSeq™ Universal Analysis System (UAS; Illumina) based on the ancestry informative and phenotype informative SNP profiles generated for each sample. Additionally, performance metrics, including profile completeness, read depth, relative locus performance, and allele coverage ratios, were evaluated and detailed for the 725 samples included in this study. While some genetic markers included in this panel performed notably better than others, performance across populations was generally consistent. The performance and population data included in this study support that accurate and reliable profiles were generated and provide valuable background information for laboratories considering internal validation studies and implementation.

Fulltext Assessment of heat stress contributing factors in the indoor environment among vulnerable populations in Klang Valley using principal component analysis (PCA)

Muhamad SN, How V, Lim FL, Md Akim A, Karuppiah K, Mohd Shabri NSA

Sci Rep, 2024 Jul 15;14(1):16265.
PMID: 39009671 DOI: 10.1038/s41598-024-67110-w

Rising global temperatures can lead to heat waves, which in turn can pose health risks to the community. However, a notable gap remains in highlighting the primary contributing factors that amplify heat-health risk among vulnerable populations. This study aims to evaluate the precedence of heat stress contributing factors in urban and rural vulnerable populations living in hot and humid tropical regions. A comparative cross-sectional study was conducted, involving 108 respondents from urban and rural areas in Klang Valley, Malaysia, using a face-to-face interview and a validated questionnaire. Data was analyzed using the principal component analysis, categorizing factors into exposure, sensitivity, and adaptive capacity indicators. In urban areas, five principal components (PCs) explained 64.3% of variability, with primary factors being sensitivity (health morbidity, medicine intake, increased age), adaptive capacity (outdoor occupation type, lack of ceiling, longer residency duration), and exposure (lower ceiling height, increased building age). In rural, five PCs explained 71.5% of variability, with primary factors being exposure (lack of ceiling, high thermal conductivity roof material, increased building age, shorter residency duration), sensitivity (health morbidity, medicine intake, increased age), and adaptive capacity (female, non-smoking, higher BMI). The order of heat-health vulnerability indicators was sensitivity > adaptive capacity > exposure for urban areas, and exposure > sensitivity > adaptive capacity for rural areas. This study demonstrated a different pattern of leading contributors to heat stress between urban and rural vulnerable populations.
