  2. Fulltext Review of the prevalence of postnatal depression across cultures
    Arifin SRM, Cheyne H, Maxwell M
    AIMS Public Health, 2018;5(3):260-295.
    PMID: 30280116 DOI: 10.3934/publichealth.2018.3.260
    The purpose of this review was to examine articles related to recent epidemiological evidence of the prevalence of maternal postnatal depression (PND) across different countries and cultures and to identify specific epidemiological studies that have been carried out exclusively in Malaysia on the prevalence of maternal PND. The review was undertaken in two stages, an initial review and an updated review. At both stages systematic literature searches of online databases were performed to identify articles on the prevalence of maternal PND. A total of 124 articles concerning research conducted in more than 50 countries were included in the final analysis. There were wide variations in the screening instruments and diagnostic tools used although the Edinburgh Postnatal Depression Scale (EPDS) was the most common instrument applied to identify PND. The prevalence of maternal PND ranged from 4.0% to 63.9%, with Japan and America recording the lowest and highest rates, respectively. Within continents, a wide variation in reported prevalence was also found. The reported rates of maternal PND in Malaysia were much higher than that previously documented with a range of 6.8-27.3%. This review indicated that the widely cited prevalence of maternal PND of 10-15% underestimates rates of PND worldwide. The reasons for this variability may not be fully explained by review methods. Future studies should evaluate the nature of women's PND experiences across cultures to explain these wide variations.

    Hirayama M, Oyama O, Asano M
    Acta Paediatr Jpn, 1993 Dec;35(6):579-82.
    PMID: 8109245
    Taking a form of Official Development Aid (ODA), the Japan International Cooperation of Welfare Services (JICWELS) and Imperial Gift Foundation, Boshi-Aiiku-Kai (Aiiku Association for Maternal and Child Health and Welfare) have extended a study program on maternal and child health (MCH) since 1989 on the commission of the Ministry of Health and Welfare. 'Community participation' is the key to the first international study program focused solely on MCH. The purpose of the program is to help to improve the planning and administration in the field of MCH. Through this, the information and experience attained in Japanese MCH activities are introduced especially by participation in community-level activities of 'Aiiku-Han' in which local citizens play a major role. The operation system of the Asian MCH Workshop, contents of the workshop, evaluation and future prospects are discussed.

  4. Natural infections with larvae of Onchocerca species type I in the human-biting black fly, Simulium nigrogilvum (Diptera: Simuliidae), in western Thailand
    Saeung A, Srisuka W, Aupalee K, Fukuda M, Otsuka Y, Taai K, et al.
    Acta Trop, 2020 Apr;204:105344.
    PMID: 31954685 DOI: 10.1016/j.actatropica.2020.105344
    Zoonotic onchocerciasis is a human infection caused by Onchocerca species of animal origins and transmitted by black fly vectors. The reported incidence of this disease has increased throughout the world. This study aims to clarify the vectorial roles of black fly species in zoonotic filarial transmission in Tak province, western Thailand. The integrated approach of morphological and DNA sequence-based analyses was used to identify species of both wild-caught female black flies and infective filarial larvae found in the infected black flies. All of 494 female black flies captured were identified as Simulium nigrogilvum, through scanning electron microscopy (SEM) and DNA sequence analyses based on the cytochrome c oxidase subunit I (COI) and subunit II (COII), and the fast-evolving nuclear elongation complex protein 1 (ECP1) genes. Four females of S. nigrogilvum harbored one to three third-stage larvae (infective larvae) in their thoraces, with an infection rate of 0.81% (4/494). All infective larvae were similar in morphology and size to one another, being identified as Onchocerca species type I (= O. sp. type A), a bovine filaria, originally reported from Japan, and also as O. sp. found in S. nodosum in Thailand, based on their body lengths and widths being 1,068-1,346 µm long by 25-28 µm wide, and morphological characters. Comparisons of cytochrome c oxidase subunit I (COI) and 12S rRNA sequences of mitochondrial DNA (mtDNA) and phylogenetic analyses with those of previous reports strongly supported that all larvae were O. sp. type I. This report is the first indicating the presence of O. sp. type I in Thailand and its vector being S. nigrogilvum.

  5. Morphological and genetic revision of cytoform 'L' of the Simulium (Simulium) tani complex from Taiwan, and cytoform 'D' of the S. (S.) suzukii complex (Diptera: Simuliidae) from the Nansei Islands, Japan
    Takaoka H, Otsuka Y, Low VL, Adler PH, Fukuda M, Huang YT, et al.
    Acta Trop, 2021 Dec;224:106124.
    PMID: 34508715 DOI: 10.1016/j.actatropica.2021.106124
    The species status of two cytoforms of two species complexes in the Simulium (Simulium) tuberosum species-group, which are almost indistinguishable in the pupal stage, was morphologically and genetically evaluated. Cytoform 'L' of the S. (S.) tani Takaoka & Davies complex, previously recognized as S. (S.) suzukii Rubtsov in Taiwan, is described as a new species, S. (S.) jianshiense. It is morphologically distinguishable as adults from two members of the S. (S.) suzukii complex: cytoform 'C' from Hokkaido, selected to represent the type of S. (S.) suzukii sensu stricto, and cytoform 'D' from Okinawa Island and, based on our chromosomal analysis, also from Amami Island. This new species is genetically separated from both cytoforms of the S. (S.) suzukii complex with a genetic distance of 5.31-6.67%. Cytoform 'D' is distinguished from cytoform 'C' by the color of the male forecoxa and relative length of the female sensory vesicle to the third maxillary palpomere. Accordingly, the name S. (S.) ryukyuense Ogata, once regarded as a synonym of S. (S.) suzukii, is revalidated and applied to cytoform 'D'. The genetic distance between S. (S.) ryukyuense and S. (S.) suzukii sensu stricto is 1.24-1.60%.

  6. Redescription of Simulium (Gomphostilbia) omutaense Ogata & Sasa (Diptera: Simuliidae) from Japan and its phylogenetic relationship with other members of the S. batoense species-group
    Takaoka H, Fukuda M, Otsuka Y, Low VL, Ya'cob Z
    Acta Trop, 2022 Jan;225:106207.
    PMID: 34687650 DOI: 10.1016/j.actatropica.2021.106207
    Simulium (Gomphostilbia) omutaense Ogata & Sasa, 1954 is the only named species in the Simulium batoense species-group of the subgenus Gomphostilbia Enderlein recorded from Honshu and Kyushu, Japan. It represents the northernmost distribution of this species-group, of which most members are distributed in the Oriental region. This species, the only member of the Simulium omutaense subgroup, is unique among the seven subgroups of the S. batoense species-group by having the pupal gill with one long filament and seven short filaments, similar to the arrangement of the pupal gill filaments in the S. zonatum subgroup of the S. epistum species-group in the same subgenus. This species is fully redescribed based on adults, pupal exuviae and mature larvae, and is most similar to species of the S. decuplum subgroup, based on adult morphological characteristics, although the pupal gill of the latter subgroup is markedly different by having 10 or 12 short filaments. Its close relationship to the S. decuplum subgroup is supported by a DNA analysis using COI gene sequences, with genetic distances of 9.30-11.02%. On the other hand, genetic distances between S. (G.) omutaense and species of the S. zonatum subgroup were 16.32-16.93%. Our study shows that a similar arrangement of the pupal gills in two different species-groups, which is rarely seen, has evolved independently and its occurrence does not necessarily reflect phylogenetic relationships.

  7. Structural proteins of Getah virus isolates from Japan and Malaysia
    Srivastava AK, Igarashi A
    Acta Virol., 1986 Mar;30(2):126-30.
    PMID: 2873729
    Purified preparations of Getah virus strains have been analysed by sodium-dodecyl-sulphate polyacrylamide gel electrophoresis (SDS-PAGE) to reveal their structural proteins. Two envelope proteins (E1 and E2) and core protein (C) were found with the prototype AMM2021 strain both under reducing and nonreducing conditions, while separation of E1 and E2 was observed only under nonreducing conditions for 3 strains isolated in Japan. Limited digestion by Staphylococcus aureus V8 protease revealed difference in the peptide patterns of E1 between AMM2021 and Japanese isolates. Mobility of E1 and E2 was slower for the virus grown in BHK21 cells compared with the virus grown in Aedes albopictus cells, indicating host-controlled modification on the envelope glycoproteins.

  8. Fulltext Acute and emergency care for thyrotoxicosis and thyroid storm
    Idrose AM
    Acute medicine & surgery, 2015 07;2(3):147-157.
    PMID: 29123713 DOI: 10.1002/ams2.104
    Thyroid hormones affect all organ systems and, in excess, can cause increased metabolic rate, heart rate, ventricle contractility, and gastrointestinal motility as well as muscle and central nervous system excitability. Thyroid storm is the extreme manifestation of thyrotoxicosis with an estimated incidence of 0.20 per 100,000 per year among hospitalized patients in Japan. The mortality of thyroid storm without treatment ranges from 80% to 100%; but with treatment, the mortality rate is between 10% and 50%. The diagnostic strategy for thyroid storm may take into consideration Burch-Wartofsky scoring or Akamizu's diagnostic criteria. Multiple treatment aims need to be addressed in managing thyroid storm effectively. This paper puts together all aspects to be considered for the management of hyperthyroidism and thyroid storm during the acute and emergency phase as well as consideration of special populations.

    Pek JH, Lim SH, Ho HF, Ramakrishnan TV, Jamaluddin SF, Mesa-Gaerlan FJC, et al.
    Acute medicine & surgery, 2016 04;3(2):65-73.
    PMID: 29123755 DOI: 10.1002/ams2.154
    Aim: We aim to examine the similarities and differences in areas of EM development, workload, workforce, and capabilities and support in the Asia region. Emerging challenges faced by our EM community are also discussed.

    Methods: The National Societies for Emergency Medicine of Hong Kong, India, Japan, Malaysia, Philippines, Singapore, South Korea, Taiwan, Thailand and Turkey participated in the joint Japanese Association of Acute Medicine (JAAM) and Asian Conference of Emergency Medicine (ACEM) Special Symposium held in October 2013 at Tokyo, Japan. The findings are reviewed in this paper.

    Results: Emergency medicine (EM) has over the years evolved into a distinct and recognized medical discipline requiring a unique set of cognitive, administrative and technical skills for managing all types of patients with acute illness or injury. EM has contributed to healthcare by providing effective, safe, efficient and cost-effective patient care. Integrated systems have developed to allow continuity of emergency care from the community into emergency departments. Structured training curriculum for undergraduates, and specialty training programs for postgraduates are in place to equip trainees with the knowledge and skills required for the unique practice of EM.

    Conclusion: The practice of EM still varies among the Asian countries. However, as a region, we strive to continue in our efforts to develop the specialty and improve the delivery of EM.

  12. Fulltext SINGLE NUCLEOTIDE POLYMORPHISM OF ECCB5 GENE OF MYCOBACTERIUM TUBERCULOSIS COMPLEX ISOLATES FROM SUSPECTED PULMONARY TB PATIENTS IN SURABAYA INDONESIA
    Kurniawati S, Soedarsono S, Aulanni'am A, Mertaniasih NM
    Afr J Infect Dis, 2018;12(2):37-42.
    PMID: 30109284 DOI: 10.21010/ajid.v12i2.6
    Background: Mycobacterium tuberculosis Complex (MTBC) is a group of Mycobacterium that causes tuberculosis (TB). TB is an infectious disease that remains a global health problem. Indonesia is one of the five countries in the world where TB is the most prevalent and became the country with tle second largest rate of TB in 2014 and 2015. MTBC has high pathogenicity that can cause infections in animals and humans. The most common route of transmission is via airborne droplet nuclei and contact with animals or humans infected with TB. MTBC has many virulence factors. One of these factors is EccB5 that is encoded by eccB5 gene. EccB5 is a transmembrane protein-conserved membrane protein and could play a role in inducing damage in host cells, macrophage infection, and may correlate with active disease. The characterization of eccB5 gene needs to be studied to determine the nucleotide sequences, which may be associated with active disease. The aim of this research was to analyze the nuclotide sequences of eccB5 gene of MTBC from suspected pulmonary tuberculosis patients, SNPs of eccB5 gene and possible correlation with the disease, especially in Indonesia.

    Materials and Methods: Samples were collected from the Tuberculosis Laboratory, Clinical Microbiology of Dr. Soetomo Hospital Surabaya Indonesia. DNA extraction used boiling extraction method and continued nucleic acid amplification using PCR techniques. Primer pairs used eccB5 SK.. The positivity of DNA specific revealed amplicon in 1592 bp. PCR product was sequenced by 1st Base (First BASE Laboratories Sdn Bhd, Selangor, Malaysia). The sequence analysis used Genetyx-Win version 10.0 (Genetyx Corporation, Tokyo, Japan).

    Results: Total isolates of Mycobacterium spp. were 28 and those that showed positive MTBC were 24 isolates and 4 nontuberculosis mycobacteria (NTM) using immunochromatographic test (ICT). The amount of homology from MTBC using blast NCBI was 99%-100%. Two SNPs were found in position c.1277 which revealed replacement of amino acid in 426 of codon position.

    Conclusion: The sequence of eccB5 gene of MTBC showed high significant homology, while proposed non-synoymous single nucleotide polymorphisms (nsSNP) may associated with clinical outcomes.

  13. Fulltext Molecular Systematics of the Firefly Genus Luciola (Coleoptera: Lampyridae: Luciolinae) with the Description of a New Species from Singapore
    Jusoh WFA, Ballantyne L, Chan SH, Wong TW, Yeo D, Nada B, et al.
    Animals (Basel), 2021 Mar 04;11(3).
    PMID: 33806564 DOI: 10.3390/ani11030687
    The firefly genus Luciola sensu McDermott contains 282 species that are distributed across major parts of Asia, Europe, Africa, Australia, and the Pacific islands. Due to phenotypic similarities, species identification using external morphological characters can be unreliable for this group. Consequently, decades of piecemeal taxonomic treatments have resulted in numerous erroneous and contentious classifications. Furthermore, our understanding of the group's evolutionary history is limited due to the lack of a robust phylogenetic framework that has also impeded efforts to stabilize its taxonomy. Here, we constructed molecular phylogenies of Luciola and its allies based on combined mitogenomes and Cytochrome c oxidase subunit 1 (COX1) sequences including a newly sequenced mitogenome of an unidentified taxon from Singapore. Our results showed that this taxon represents a distinct and hitherto undescribed evolutionary lineage that forms a clade with L. filiformis from Japan and L. curtithorax from China. Additionally, the Singaporean lineage can be differentiated from other congeners through several external and internal diagnostic morphological characters, and is thus described herein as a new species. Our phylogeny also strongly supported the paraphyly of Luciola with regard to L. cruciata and L. owadai, which were inferred to be more closely related to the genus Aquatica as opposed to other members of Luciola sensu stricto. The genus Hotaria was inferred as a derived clade within Luciola (sister to L. italica), supporting its status as a subgenus of Luciola instead of a distinct genus. This is the first time since 1909 that a new species of luminous firefly has been discovered in Singapore, highlighting the need for continued biodiversity research, even in small, well-studied and highly developed countries, such as Singapore.

    MyJurnal
    The objective of this study was to investigate the effect of various luting cement systems on bond strength of fibre-reinforced posts to root canal dentine. 40 extracted single rooted sound premolar teeth were root filled, decoronated and randomly divided into four groups. Fibre posts, Aestheti- Plus™ (Bisco,Inc. Schaumburg, IL, USA) were cemented using four luting cements: Group A (control): Elite 100® Zinc phosphate (GC Corp, Japan), Group B: Calibra ™ Esthetic Resin Cement (Dentsply Caulk, USA), Group C: RelyX ARC Adhesive Resin (3M ESPE), Group D: RelyX Unicem Aplicap (3M ESPE). Each root was sliced into 2 discs representing the coronal and middle portions of the root canal giving rise to 20 specimens per group. Bond strength was determined using push-out tests and data was analyzed using SPSS version 14.0. The mean bond strength of Group A to Aestheti-Plus™ post was 7.71 MPa (±2.51) and Group B was 5.69 MPa (±3.23). Group C exhibited the lowest mean bond strength, 4.29 MPa (±3.53) while the highest bond strength was obtained from Group D, 7.98 MPa (±2.61). One way ANOVA showed significant interaction between all groups (p=.OOI). Post-hoc Bonferroni test reve;iled that bond strength of Group C was significantly lower compared to Group A (p=.008) and D (p=.004). In conclusion, the mean bond strength of Aestheti- Plus™ post to root canal dentine was highest when cemented with RelyX Unicem resin cement followed by Elite 100® zinc phosphate cement, Calibra and RelyX ARC resin cements. However, the bond strengths of Cali bra and RelyX Unicem resin cements were not significantly different from Elite 100® zinc phosphate cement.

  18. Haemorrhagic fever with renal syndrome: clinical, virological and epidemiological perspectives
    Chan YC, Wong TW, Yap EH
    Ann Acad Med Singap, 1987 Oct;16(4):696-701.
    PMID: 2895603
    Haemorrhagic fever with renal syndrome (HFRS) is caused by a group of RNA viruses within the family of Bunyaviridae known as hantaviruses. The classical, severe form of HFRS is characterized by fever, headache, abdominal and lumbar pain, proteinuria, haemorrhagic phenomena, shock and renal failure. The disease is associated with the prototype Hantaan virus and occurs in rural areas of Korea and China with Apodemus mice as reservoir hosts. A clinically less severe form of HFRS, which is caused by Seoul virus, occurs in urban areas with the house rat Rattus novegicus as the main reservoir host. The disease in nonendemic areas may be atypical and patients with symptoms the hepatitis and minimal renal involvement have been observed in Malaysia. Outbreaks of HFRS in humans involving infected laboratory rat colonies have occurred in several medical centres in various countries. Hantaviruses cause a chronic, asymptomatic infection in rodents which excrete the virus in their lungs, saliva and urine. Man becomes infected mainly by inhalation of infected droplets from healthy rodent carriers. Seroepidemiological studies using mainly the indirect immunoflourescent antibody test of sera from humans and rats showed that hantaviruses have a worldwide distribution.

    Ann Acad Med Singap, 1989 Nov;18(6):642-5.
    PMID: 2624412
    Age-standardised death rates, for ages 35-64 years in both sexes, from ischaemic heart disease, cerebrovascular disease, and hypertensive disease for Chinese, Malays, and Indians in Singapore (1980-84) have been compared with those in England and Wales, USA and Japan (1982). For ischaemic heart disease Indians have the highest mortality, then Malays, with Chinese less than the Western countries but more than Japan. For cerebrovascular disease the Malays have highest mortality, then Indians, then Chinese, followed by Japan, England and Wales, and USA in that order. For hypertensive disease it is again Malays, then Indians, then Chinese, but followed by the different order of USA, England and Wales, and Japan. The differences are discussed in the light of declining trends in mortality from these disease in Singapore over the preceding 25 years. The special problems of ischaemic heart disease in Indians and hypertension and it's sequelae in Malays are highlighted.

    Abugassa I, Sarmani SB, Samat SB
    Appl Radiat Isot, 1999 Jun;50(6):989-94.
    PMID: 10355102
    This paper focuses on the evaluation of the k0 method of instrumental neutron activation analysis in biological materials. The method has been applied in multielement analysis of human hair standard reference materials from IAEA, No. 085, No. 086 and from NIES (National Institute for Environmental Sciences) No. 5. Hair samples from people resident in different parts of Malaysia, in addition to a sample from Japan, were analyzed. In addition, human kidney stones from members of the Malaysian population have been analyzed for minor and trace elements. More than 25 elements have been determined. The samples were irradiated in the rotary rack (Lazy Susan) at the TRIGA Mark II reactor of the Malaysian Institute for Nuclear Technology and Research (MINT). The accuracy of the method was ascertained by analysis of other reference materials, including 1573 tomato leaves and 1572 citrus leaves. In this method the deviation of the 1/E1+ alpha epithermal neutron flux distribution from the 1/E law (P/T ratio) for true coincidence effects of the gamma-ray cascade and the HPGe detector efficiency were determined and corrected for.
