    BACKGROUND: Child marriage, a marriage that involves someone under the age of 18 years, is a long-standing social issue in Sarawak state, Malaysia. The state has taken several measures to improve situations of inequity for women who get married early; however, the practice is still a common part of the tradition and culture. The aim of this study was to explore the factors leading to child marriage in Sarawak state, Malaysia.

    METHODS: This was an exploratory qualitative study conducted via semi-structured interviews with twenty-two women who were married when they were younger than 18 years old in Kuching, Sarawak, Malaysia. Participants were recruited through purposive and convenient sampling with the use of data from a reproductive health clinic and recruitment in villages. Thematic analysis was used for data analysis.

    RESULTS: Four overarching themes were identified: health risk behaviour, family poverty, early marriage as fate, and family disharmony.

    CONCLUSIONS: In-depth understanding of the unique factors leading to child marriage locally will facilitate the introduction of new approaches to interventions to eradicate child marriage in Sarawak state, Malaysia.

    With both theories and empirical studies supporting the benefits of having a romantic relationship, there remains an increasing tendency of staying single being documented globally. It is thus important to understand the antecedent factors of such voluntary single movement. Guided by the Investment Model of Commitment (IMC) process, the roles of subjective socioeconomic status (SSES), relational mobility, and desirability of control in attitudes toward singlehood were investigated. A total of 1,108 undergraduate students from Malaysia (n=444), Japan (n=316), and India (n=348) answered an online survey consisting of the Attitudes toward Singlehood Scale, MacArthur Scale of SSES, Relational Mobility Scale, Desirability of Control Scale, Mini-Social Phobia Inventory, and Single Item Narcissism Scale. Hierarchical multiple regression analysis showed a persistent positive relationship between desirability of control, but not socioeconomic status and relational mobility, with attitudes toward singlehood, even after statistically excluding the effects of social anxiety and narcissism. A similar pattern was also observed among those who were currently single. Moreover, an interaction effect of socioeconomic status and relational mobility was found in further exploratory analysis. The results highlight that retaining the autonomy and flexibility of managing one's own life and financial concern are the key reasons young adults prefer staying single to engaging in a romantic relationship. Implications and recommendations for future research are also presented in this study.

    BACKGROUND: Worldwide, international retirement migration is growing in its popularity and Japanese retirees choose Malaysia as their most preferred destination. This study examines the pertinent issues related to healthcare services as experienced by Japanese retirees in this country.

    METHODS AND RESULTS: From January to March 2015, we conducted focus group discussions with 30 Japanese retirees who live in Kuala Lumpur and Ipoh. Guided by the social-ecological model, we discovered seven pertinent themes: 'language barriers','healthcare decisions', 'medical check-ups','healthcare insurance', 'nursing and palliative care', 'trust and distrust of healthcare services', and 'word-of-mouth information'.

    DISCUSSION: We identified seven pertinent issues related to healthcare services among Japanese retirees in Malaysia, of which four are especially important. These issues are explained as integrated themes within the social-ecological model. Language barriers prohibit them from having difficulty accessing to healthcare in Malaysia, but lack of will to improve their language skills exist among them. For that reason, they rely heavily on word-of-mouth information when seeking for healthcare. As a consequence, some develop feelings of trust and distrust of healthcare services. In addition, we have identified the needs for provide nursing and palliative care among Japanese retirees in Malaysia.

    CONCLUSION: Based on the magnitude of the discussion, we concluded that there are four crucial healthcare issues among Japanese retirees; 'language barriers', 'trust and distrust of healthcare services', 'word-of-mouth information' and 'nursing and palliative care'. We propose that further dialogue by healthcare stakeholders should be carried out to improve further the healthcare service provisions for Japanese retirees in Malaysia.

    OBJECTIVE: To examine individual, familial, community and societal issues surrounding the reasons for child marriage in Kelantan, Malaysia.

    DESIGN: Qualitative study by means of semistructured interviews with women and key informants, using social-ecological model as a conceptual framework.

    SETTING: Interviews were conducted in Kota Bharu district, Kelantan, a northeast state in Peninsular Malaysia.

    PARTICIPANTS: Eighteen women of reproductive age (18 to 44 years old) that experienced their first marriage below the age of 18, as well as five key informants, consisting of a government officer, a community leader, an officer from religious department and two mothers. The women were recruited from a reproductive health clinic. The key informants who had specialised knowledge related to child marriage were selectively chosen.

    RESULTS: Three themes emerged that aligned with the social-ecological model: immaturity in decision-making, family poverty and religious and cultural norms.

    CONCLUSIONS: The findings imply that sex education and awareness-building activities regarding the consequences of child marriage must be implemented to eradicate child marriage in Malaysia. Such implementation must be coordinated as a team-based approach involving experts in such fields as law, religion, psychology, social-welfare and public health. In order to increase the awareness of child marriage consequences, the target for awareness must extend not only to the adolescent girls and their families, but also to the community and society at large by clearly communicating the negative consequences of and addressing the drivers for child marriage.

    In this study, we synthesized findings from qualitative studies to identify the key factors that influence child marriage. We used a meta-ethnographic approach coupled with thematic synthesis. We searched literature from nine databases, which were in English language, covering areas in public health, psychology, and social science between 2008 and 2018. Twelve studies were included in the synthesis. We identified six main themes: human insecurity and conflict; legal issues; family values and circumstances; religious beliefs; individual circumstances, beliefs, and knowledge; and social norms. Our findings highlight the impact of human insecurity and conflict, as well as legal issues. In spite of global progress scaling up legislation against child marriage, the legal framework is insufficiently enforced in many settings. Most of the included studies were from the Middle East, Africa, and South Asia. Studies from other parts of the world such as Latin America and Southeast Asia, which have the highest rates of child marriage, are needed.

    Significant sociocultural barriers to sexual and reproductive health (SRH) information influence what is acceptable to discuss and learn within the Malaysian community. To address gaps in their knowledge, adolescents routinely turn to the Internet. This study identifies the ways they navigate SRH information found online. One-on-one interviews were conducted with 17 Malaysian adolescents. The data were analysed with reflexive thematic analysis. Participants navigate SRH information using intuitive strategies, known locally as pandai-pandai. This important cultural concept involves balancing between adherence to social norms and resourcefulness in problem-solving. Pandai-pandai strategies were observed in three domains: (1) navigating SRH sources, (2) evaluating and verifying SRH information, and (3) processing SRH information. Malaysian adolescents' strategies for evaluating SRH information extend beyond traditional critical evaluation models and are driven by emotional, social, and cultural criteria, requiring a reconsideration of what constitutes critical evaluation in this context.

    Rapidly accumulating genetic data from environmental sequencing approaches have revealed an extraordinary level of unsuspected diversity within marine phytoplankton,1-11 which is responsible for around 50% of global net primary production.12,13 However, the phenotypic identity of many of the organisms distinguished by environmental DNA sequences remains unclear. The rappemonads represent a plastid-bearing protistan lineage that to date has only been identified by environmental plastid 16S rRNA sequences.14-17 The phenotypic identity of this group, which does not confidently cluster in any known algal clades in 16S rRNA phylogenetic reconstructions,15 has remained unknown since the first report of environmental sequences over two decades ago. We show that rappemonads are closely related to a haptophyte microalga, Pavlomulina ranunculiformis gen. nov. et sp. nov., and belong to a new haptophyte class, the Rappephyceae. Organellar phylogenomic analyses provide strong evidence for the inclusion of this lineage within the Haptophyta as a sister group to the Prymnesiophyceae. Members of this new class have a cosmopolitan distribution in coastal and oceanic regions. The relative read abundance of Rappephyceae in a large environmental barcoding dataset was comparable to, or greater than, those of major haptophyte species, such as the bloom-forming Gephyrocapsa huxleyi and Prymnesium parvum, and this result indicates that they likely have a significant impact as primary producers. Detailed characterization of Pavlomulina allowed for reconstruction of the ancient evolutionary history of the Haptophyta, a group that is one of the most important components of extant marine phytoplankton communities.

    INTRODUCTION: The incidence and mortality of lung cancer are highest in Asia compared with Europe and USA, with the incidence and mortality rates being 34.4 and 28.1 per 100,000 respectively in East Asia. Diagnosing lung cancer at early stages makes the disease amenable to curative treatment and reduces mortality. In some areas in Asia, limited availability of robust diagnostic tools and treatment modalities, along with variations in specific health care investment and policies, make it necessary to have a more specific approach for screening, early detection, diagnosis, and treatment of patients with lung cancer in Asia compared with the West.

    METHOD: A group of 19 advisors across different specialties from 11 Asian countries, met on a virtual Steering Committee meeting, to discuss and recommend the most affordable and accessible lung cancer screening modalities and their implementation, for the Asian population.

    RESULTS: Significant risk factors identified for lung cancer in smokers in Asia include age 50 to 75 years and smoking history of more than or equal to 20 pack-years. Family history is the most common risk factor for nonsmokers. Low-dose computed tomography screening is recommended once a year for patients with screening-detected abnormality and persistent exposure to risk factors. However, for high-risk heavy smokers and nonsmokers with risk factors, reassessment scans are recommended at an initial interval of 6 to 12 months with subsequent lengthening of reassessment intervals, and it should be stopped in patients more than 80 years of age or are unable or unwilling to undergo curative treatment.

    CONCLUSIONS: Asian countries face several challenges in implementing low-dose computed tomography screening, such as economic limitations, lack of efforts for early detection, and lack of specific government programs. Various strategies are suggested to overcome these challenges in Asia.
