Dengue remains a public health threat that consumes a significant number of resources for its prevention and control. This systematic review aimed to solidify recent costing evidence in dengue management among South East Asian (SEA) countries. All studies conducted between 2010 and 2020 were retrieved using four international databases i.e. PubMed, Scopus, Web of Science, and Emerald Insight. The review was reported according to PRISMA guidelines. Quality assessments were done independently by two reviewers using a checklist adapted for the cost of illness studies. We identified 13 original articles representing several SEA countries. Among the common reported costing measure include total cost/ health expenditure; direct medical cost; direct non-medical cost; and indirect cost. The estimated total cost for dengue management varied between countries largely due to the difference in the total incidence of dengue cases. The estimated cost spent on dengue per capita GDP ranges from less than 0.001% to 0.1%, depending on the recorded number of dengue cases of the year. The majority of the articles focused on the economic burden from the perspective of treatment such as hospitalization and ambulatory care. In a nutshell, the economic burden of managing dengue infection is costly and the evidence suggests a steady increase in health expenditure with the growing number of dengue cases

Socio-Ecological Framework on Risk of Prolonged Dengue Outbreak in Seremban District: A Qualitative Study IntroductionA prolonged duration of a dengue outbreak in a locality poses a detrimental risk to the susceptible population. There have been limited studies looking into the socio-ecological factors that can be modified to break the chain of transmission. Therefore, this study aimed to explore and identify the socio-ecological attributes experienced by the health authority in the Seremban district.MethodsA qualitative study was performed using an in-depth interview (IDI) technique based on semi-structured questionnaires. Results were thematically analysed when theoretical saturation was achieved.ResultsA total of 12 respondents participated in this study, representing various backgrounds and involved in dengue control activities. There were nine modifiable socio-ecological themes generated, namely (1) illegal dumpsite, (2) illegal gardens, (3) illegal man-made structures, (4) old unused items, (5) idle damaged vehicles, (6) construction site, (7) drainage system, (8) physical structure, and (9) lack of community engagement. A model framework was conceptualised from the analysis. The health authority identified that these issues require urgent attention and collaborative action by various stakeholders.ConclusionThe identified socio-ecological factors have been a challenge for the health authority. Nevertheless, identifying these attributes signifies the key to tackling the prolonged duration of the dengue outbreak. Ultimately, a multi-agency approach and community participation are vital to ensure a sustainable vector control program.

Breastfeeding Under Siege: A Scoping Review of Flood Impacts on Lactating Mothers Introduction Floods, as one of the most frequent and devastating natural disasters, create unique challenges for breastfeeding mothers. However, there is limited understanding of the multifaceted impacts of floods on breastfeeding practices. This review aims to examine the impact of floods on breastfeeding mothers and aims to guide disaster response strategies to support maternal and infant health. Methods A scoping review was conducted using the Arksey and O'Malley framework and the PRISMA-ScR methodology. A systematic search of PubMed, Web of Science, and Scopus databases identified eight studies that met predefined inclusion criteria. Eligibility criteria encompassed peer-reviewed articles with quantitative, qualitative, or mixed methods designs. Studies were included if they focused on breastfeeding mothers affected by floods. Results Eight studies from diverse geographic regions reported significant impacts on breastfeeding practices, including environmental hazard, sociocultural, malnutrition and psychosocial impacts dimensions. Displacement and lack of privacy (e.g., overcrowded shelters, absence of breastfeeding-friendly spaces) disrupted feeding routines. Additionally, maternal malnutrition, stress, and unregulated distribution of formula milk further undermined breastfeeding efforts. Conclusions Flood disasters pose significant challenges in terms of environmental hazard, sociocultural, malnutrition and psychosocial impacts on breastfeeding mothers, jeopardizing maternal and infant well-being. Addressing these issues requires integrated disaster response strategies, including breastfeeding-friendly facilities, nutritional aid, and mental health support. These findings underscore the importance of prioritizing breastfeeding in disaster preparedness and response plans to enhance resilience and reduceinfant mortality during crises.

Introduction: The term "urban heat island" refers to a phenomenon that occurs when temperatures in urban areas are higher than those in the areas that surround them (suburban area). Methods: The urban heat island phenomenon can result in increase of energy consumption, increase of air pollution, decrease of water quality, and increase of greenhouse gas emissions, all of which have the potential to negatively impact people in a variety of ways. Results: In this review we identified certain groups such as elderly, children, woman, pregnant woman, single person, and minority communities, who are living in dense area or in high rise building, low education level, low income, work in outdoor environment and had pre-existing illnesses may face health issues or insufficient resources to cope with the heat in urban area. There were more susceptible to heat-related illnesses and mortality, particularly during extreme heat events. Conclusions Recognising these vulnerable populations is crucial to develop effective strategies to mitigate the effects of urban heat islands and protect them. This can aid policy makers and urban planners to implement targeted interventions to address these issues. Keywords Urban heat island – UHI – Vulnerable population – Heat exposure

Introduction: The construction workers are performing manual tasks in harsh conditions. Various environmental risk factors could have significant influence on work fatigue. Methods: This review article discussed the environmental causal factors which involved in work fatigue development in the occupational health perspective, with the aim in enhancing the body of knowledge specifically in the construction industry so that mitigation measures and interventions can be formulated and implemented for fatigue prevention and productivity enhancement. Results: Data derived from a total of 11 relevant articles identified climatic heat, vibration and elevation change as the major risk factors that associated with work fatigue. The mechanism of the environmental factors’ influences on muscle, mental and visual fatigue were understood, pointedly the underlying physiological alteration. Additionally, appropriate preventive measures in accordance to the OSHA guides including work-break cycles, work management, cool-down arrangements with drinking water were discussed. The limitation of existing OSH requirements on work limits at heat exposure was recognized, including the lack of consideration on personal characteristics therefore might inaccurately estimate the personal heat tolerance time. Conclusions The proper understanding of the environmental stressors and its impact on workers production and safety performance may help construction organisations and regulatory body to develop strategies for workers protection and fatigue-related accidents prevention.

Pregnant adolescents have been shown to have a higher incidence of health and non-health-related complications that affect both mothers and infants. These include increased risk of pregnancy-related diseases such as anemia and pre-eclampsia, preterm and low-birth-weight babies, as well as other social consequences such as educational and financial difficulties. This mini review evaluates selected articles which explain the attitudes, knowledge, behavior and other risk factors associated with pregnancy among adolescents in developing countries. It also revealed that inadequate knowledge among adolescents about reproductive and sexual health, other social, cultural and peer influences, parenting values, and poor financial and educational status were factors that contribute to adolescent pregnancy. Likewise, a lack of support from parents, educators and healthcare workers had negative impacts on healthy sexual behavior among adolescents, which may ultimately lead to adolescent pregnancy. We conclude that the factors discussed in this review need to be evaluated and taken into consideration by policymakers and healthcare workers when formulating strategies to prevent pregnancies among adolescents.

Background and aims: Forest bathing or Shinrin-Yoku is a practice of being mindful of nature and it offers multiple health benefits in both physiological and psychological factors. This study aimed to determine the knowledge and attitude of Universiti Kebangsaan Malaysia (UKM) medical students towards forest bathing and its relationship with the sociodemographic factors. Materials and methods: A total of 165 UKM medical students were recruited using proportionate random sampling. The subjects were then categorized based on the academic year (Year 1 - Year 5). Exclusion criteria includes those who deferred their academic year and/or who were hospitalized. A questionnaire was given via a google form consisting of sociodemographic data details and 15 questions for each knowledge and attitude on forest bathing. Results: The prevalence of good knowledge and good attitude of UKM medical students towards forest bathing were 64.2% (n=106) and 50.9% (n=84) respectively. Female medical students had a good knowledge (n=63, 73.3%) and good attitude (n=52, 60.5%) compared to male medical students' knowledge (n=43, 54.4%) and attitude (n=32, 10.5%) leading to a p-value of 0.012 and p-value of 0.010. Otherwise, other sociodemographic factors including race, level of medical year and level of lifestyle did not affect participants' knowledge and attitude on forest bathing. Conclusion Majority of UKM medical students have a higher prevalence of good knowledge compared to good attitude on forest bathing. Therefore, intervention is recommended especially towards male medical students as forest bathing has enough evidence as preventive medicine.

Introduction: Heatwave can increase the risk for heat-related illnesses and mortality. Many studies showed certain population are vulnerable to heatwave such as elderly, children and low-income households. However, the findings were inconsistent. Therefore, this systematic review provides a comprehensive review on heatwave impact and vulnerability factors on the mortality and morbidity impacts. Methodology: Five electronic databases (Pubmed, Ebsco Host, WOS, OVID Medline and Scopus) were primary searching tools to retrieve relevant literatures. This systematic review used the Medical Subject Heading (MESH) terms and keywords. An additional searching tool (Google Scholar) was used to seek further information and minimize missed evidence. We selected the literature based on the inclusion criteria (empirical full-text article, English language and published between 2010-2021). Two authors were assigned in each step of the process, starting from screening of the title, abstract and full text based on the inclusion criteria, data extraction and quality appraisal. Mixed-Method Appraisal Tool (MMAT) was utilized to assess the quality of selected articles. Thematic analysis and narrative approach were used to describe the findings. Conclusion This review presents the comprehensive evidence-based regarding heatwave impact and associated vulnerable groups for better understanding and effective preventive measure planning to reduce the impact of heatwave on population health.

Introduction: Influenza outbreak causes high economic burden to Malaysia and other countries in South East Asia. Scientists have found a relatively new way to detect influenza outbreaks early thus reducing the burden of disease by early intervention. This new technology is a social network information system which uses Facebook or Twitter data to detect potential influenza cases. Such system is good to be developed by the Malaysian government as it can detect influenza outbreaks three weeks earlier than the normal pathway. However, to implement this we require good evidence that the development will be accepted by potential users. Objective: This study was looking at the acceptance towards using social network information system among public health workers. Materials and Method: This study was done on 205 Malaysian One Health University Network (MyOHUN) members through email and physical survey. Results: Results show that 62.4% public health workers accepted the use technology. The acceptance was shown to be associated with performance expectancy (p<0.05). However, unlike the very famous Unified Theory of Acceptance and Use of Technology (UTAUT) model, the acceptance of social network information system was not associated with effort expectancy, social factors, facilitating conditions and socio-demographic factors. Therefore, it is suggested that social network information system be developed by the authorities in Malaysia, and be developed in a way that the system could strongly increase performance in detection of outbreak earlier than the current normal pathways. As such the system to be accepted and used, it must be sensitive, specific and be able to detect influenza outbreak early Conclusion: The development of social network information system is feasible as it is highly accepted and it’s potential to improve early detection of influenza outbreak.
