Background: Nearly half of the world is at risk of developing dengue infection. Dengue virus is the causative agent behind this public healthcare concern. Millions of dengue cases are reported every year, leading to thousands of deaths. The scientific community is working to develop effective therapeutic strategies in the form of vaccines and antiviral drugs against dengue. Methods: In this review, a methodological approach has been used to gather data from the past five years to include the latest developments against the dengue virus. Results: Different therapeutics and antiviral targets against the dengue virus are at different stages of development, but none have been approved by the FDA. Moreover, various vaccination strategies have also been discussed, including attenuated virus vaccines, recombinant subunit vaccines, viral vector vaccines, DNA vaccines, nanotechnology, and plant-based vaccines, which are used to develop effective vaccines for the dengue virus. Many dengue vaccines pass the initial phases of evaluation, but only two vaccines have been approved for public use. DENGVAXIA is the only FDA-approved vaccine against all four stereotypes of the dengue virus, but it is licensed for use only in individuals 6–16 years of age with laboratory-confirmed previous dengue infection and living in endemic countries. Takeda is the second vaccine approved for use in the European Union, the United Kingdom, Brazil, Argentina, Indonesia, and Thailand. It produced sustained antibody responses against all four serotypes of dengue virus, regardless of previous exposure and dosing schedule. Other dengue vaccine candidates at different stages of development are TV-003/005, TDENV PIV, V180, and some DNA vaccines. Conclusion: There is a need to put more effort into developing effective vaccines and therapeutics for dengue, as already approved vaccines and therapeutics have limitations. DENGVAXIA is approved for use in children and teenagers who are 6–16 years of age and have confirmed dengue infection, while Takeda is approved for use in certain countries, and it has withdrawn its application for FDA approval.

The social enterprise concept, a business with specific social objectives, has been questioned by scholars and practitioners for its sustainability. More importantly, a paucity of research exists on how a social enterprise can be sustainable, indicating the necessity of developing a sustainable model of social enterprise, particularly in the Asian context. Filling in the gap in the literature, the present study’s prime objective is to explore a sustainable social enterprise model. The bodies of knowledge on social enterprise and sustainable enterprise are reviewed, followed by identifying a sustainable social enterprise model for exploration. The identified model is among the few sustainable social enterprise models available, thus making it appropriate for the exploration. To explore the model, the phenomenological paradigm is adopted. The study uses the case study approach with open-ended, semi-structured interview methods as well as documentation to explore a case enterprise called Amphawa Chaipattananurak (ACCP) in Thailand. To ensure data validity, the data, method, investigator, and theory triangulation methods are adopted. Ninety-five stakeholder informants were interviewed, ranging from the management team, staff, community people, and visitors to customers. In terms of analysis, the working analytical framework is adopted to analyze the collected data. Findings indicate that the ACCP practices and outcomes are consistent with those of the sustainable social enterprise model, indicating the model’s applicability. Based on the findings, a refined sustainable social enterprise model is derived. Limitations, future research directions, theoretical contributions and implications, and managerial implications are also discussed. Full article

The emergence of the lumpy skin disease virus (LSDV) was first detected in north-eastern Thailand in March 2021. Since then, the abrupt increase of LSD cases was observed throughout the country as outbreaks have spread rapidly to 64 out of a total of 77 provinces within four months. Blood, milk, and nodular skin samples collected from affected animals have been diagnosed by real-time PCR targeting the p32 gene. LSDV was isolated by primary lamb testis (PLT) cells, followed by Madin-Darby bovine kidney (MDBK) cells, and confirmed by immunoperoxidase monolayer assay (IPMA). Histopathology and immunohistochemistry (IHC) of a skin lesion showed inclusion bodies in keratinocytes and skin epithelial cells. Phylogenetic analyses of RPO30 and GPCR genes, and the whole genome revealed that Thai viruses were closely related to the vaccine-derived recombinant LSDV strains found previously in China and Vietnam. Recombination analysis confirmed that the Thai LSDV possesses a mosaic hybrid genome containing the vaccine virus DNA as the backbone and a field strain DNA as the minor donor. This is an inclusive report on the disease distributions, complete diagnoses, and genetic characterisation of LSDV during the first wave of LSD outbreaks in Thailand. Full article

Serious games have been shown to be effective learning tools in various disciplines, including dental education. Serious-game learning environments allow learners to improve knowledge and skills. GRAPHIC (Games Research Applied to Public Health with Innovative Collaboration), a serious game for dental public health, was designed to simulate a town, enabling students to apply theoretical knowledge to a specific population by selecting health promotion initiatives to improve the oral health of the town population. This study employed a literature-based evaluation framework and a sequential explanatory mixed-methods research design to evaluate the use of GRAPHIC among final-year dental undergraduates across two learning contexts: King’s College London in the United Kingdom and Mahidol University in Thailand. Two hundred and sixty-one students completed all designated tasks, and twelve participated in semi-structured interviews. The findings demonstrated knowledge improvement after game completion based on pre- and post-knowledge assessments, and the students’ perceptions of the game as an interactive and motivational learning experience. The evaluation identified five serious-game dimensions and clear alignment between these dimensions, demonstrating the impact of serious games in dental public health and, more widely, in healthcare education.

In the event that the COVID-19 pandemic spreads across various stock markets, this study may be deemed as one of the primary studies to evaluate cross-market interactions. The study examines the spread of contagious effects originating from developed economies (the United States, the United Kingdom, and Japan) to selected emerging markets (China, India, Thailand, Taiwan, Egypt, South Africa, Saudi Arabia, and the United Arab Emirates). The countries studied are classified into three regions: developed economies, Asia, and Africa and the Middle East. The crisis period is identified with the deployment of the Markov regime-switching model. The conditional correlations are compared before and after the crisis episode using the time-varying multivariate DCC-GARCH model. The findings confirm that certain emerging markets are experiencing contagion from developed markets, while others remain unaffected. Overall, investors in the two regions examined (Asia, and Africa and the Middle East) have comparable diversification options. The findings are expected to bolster policymakers and international agencies in developing post-crisis measures. Full article

Bluetongue virus (BTV) and African horse sickness virus (AHSV) cause economically important diseases that are currently exotic to the United Kingdom (UK), but have significant potential for introduction and onward transmission. Given the susceptibility of animals kept in zoo collections to vector-borne diseases, a qualitative risk assessment for the introduction of BTV and AHSV to ZSL London Zoo was performed. Risk pathways for each virus were identified and assessed using published literature, animal import data and outputs from epidemiological models. Direct imports of infected animals, as well as wind-borne infected Culicoides, were considered as routes of incursion. The proximity of ongoing disease events in mainland Europe and proven capability of transmission to the UK places ZSL London Zoo at higher risk of BTV release and exposure (estimated as low to medium) than AHSV (estimated as very low to low). The recent long-range expansion of AHSV into Thailand from southern Africa highlights the need for vector competence studies of Palearctic Culicoides for AHSV to assess the risk of transmission in this region.

The burden of AIDS-defining cancers has remained relatively steady for the past two decades, whilst the burden of non-AIDS-defining cancer has increased. Here, we conduct a study to describe mortality trends attributed to HIV-associated cancers in 31 countries. We extracted HIV-related cancer mortality data from 2001 to 2018 from the World Health Organization Mortality Database. We computed age-standardized death rates (ASDRs) per 100,000 population using the World Standard Population. Data were visualized using Locally Weighted Scatterplot Smoothing (LOWESS). Data for females were available for 25 countries. Overall, there has been a decrease in mortality attributed to HIV-associated cancers among most of the countries. In total, 18 out of 31 countries (58.0%) and 14 out of 25 countries (56.0%) showed decreases in male and female mortality, respectively. An increasing mortality trend was observed in many developing countries, such as Malaysia and Thailand, and some developed countries, such as the United Kingdom. Malaysia had the greatest increase in male mortality (+495.0%), and Canada had the greatest decrease (−88.5%). Thailand had the greatest increase in female mortality (+540.0%), and Germany had the greatest decrease (−86.0%). At the endpoint year, South Africa had the highest ASDRs for both males (16.8/100,000) and females (19.2/100,000). The lowest was in Japan for males (0.07/100,000) and Egypt for females (0.028/100,000). Full article

Background and objectives: To explore the ethical and legal complexities arising from the controversial issue of surrogacy, particularly in terms of how they affect fundamental rights of children and parents. Surrogacy is a form of medically-assisted procreation (MAP) in which a woman “lends” her uterus to carry out a pregnancy on behalf of a third party. There are pathological conditions, such as uterine agenesis or hysterectomy outcomes, that may prevent prospective mothers from becoming pregnant or carry a pregnancy to term; such patients may consider finding a surrogate mother. Many issues relating to surrogacy remain unresolved, with significant disagreements and controversy within the scientific community and public opinion. There are several factors called into play and multiple parties and stakeholders whose objectives and interests need to somehow be reconciled. First and foremost, the authors contend, it is essential to prioritize and uphold the rights of children born through surrogacy and heterologous MAP. Materials and methods: To draw a parallel between Italy and the rest of the world, the legislation in force in twelve European countries was analyzed, eleven of which are part of the European Union (France, Germany, Italy, Spain, Greece, Netherlands, Belgium, Denmark, Lithuania, Czech Republic and Portugal) and three non-members of the same (United Kingdom, Ukraine and Russia), as well as that of twelve non-European countries considered exemplary (United States, Canada, Australia, India, China, Thailand, Israel, Nigeria and South Africa); in particular, legislative sources and legal databases were drawn upon, in order to draw a comparison with the Italian legislation currently in force and map out the evolution of the Italian case law on the basis of the judgments issued by Italian courts, including the Constitutional and Supreme Courts and the European Court of Human Rights (ECHR); search engines such as PubMed and Google Scholar were also used, by entering the keywords “surrogacy” and “surrogate motherhood”, to find scientific articles concerning assisted reproduction techniques with a close focus on surrogacy. Results: SM is a prohibited and sanctioned practice in Italy; on the other hand, it is allowed in other countries of the world, which leads Italian couples, or couples from other countries where it is banned, to often contact foreign centers in order to undertake a MAP pathway which includes surrogacy; in addition, challenges may arise from the legal status of children born through surrogacy abroad: to date, in most countries, there is no specific legislation aimed at regulating their legal registration and parental status. Conclusion: With reference to the Italian context, despite the scientific and legal evolution on the subject, a legislative intervention aimed at filling the regulatory gaps in terms of heterologous MAP and surrogacy has not yet come to fruition. Considering the possibility of “fertility tourism”, i.e., traveling to countries where the practice is legal, as indeed already happens in a relatively significant number of cases, the current legislation, although integrated by the legal interpretation, does not appear to be effective in avoiding the phenomenon of procreative tourism. Moreover, to overcome some contradictions currently present between law 40 and law 194, it would be appropriate to outline an organic and exhaustive framework of rules, which should take into account the multiplicity of interests at stake, in keeping with a fair and sustainable balance when regulating such practices.

This study aimed to examine the global burden, risk factors, and trends of esophageal cancer based on age, sex, and histological subtype. The data were retrieved from cancer registries database from 48 countries in the period 1980–2017. Temporal patterns of incidence and mortality were evaluated by average annual percent change (AAPC) using joinpoint regression. Associations with risk factors were examined by linear regression. The highest incidence of esophageal cancer was observed in Eastern Asia. The highest incidence of adenocarcinoma (AC) was found in the Netherlands, the United Kingdom, and Ireland. A higher AC/squamous cell carcinoma (SCC) incidence ratio was associated with a higher prevalence of obesity and elevated cholesterol. We observed an incidence increase (including AC and SCC) in some countries, with the Czech Republic (female: AAPC 4.66), Spain (female: 3.41), Norway (male: 3.10), Japan (female: 2.18), Thailand (male: 2.17), the Netherlands (male: 2.11; female: 1.88), and Canada (male: 1.51) showing the most significant increase. Countries with increasing mortality included Thailand (male: 5.24), Austria (female: 3.67), Latvia (male: 2.33), and Portugal (male: 1.12). Although the incidence of esophageal cancer showed an overall decreasing trend, an increasing trend was observed in some countries with high AC/SCC incidence ratios. More preventive measures are needed for these countries. Full article

In recent years, production of biohydrogen and biomethane (or a mixture of these; biohythane) from organic wastes using two-stage bioreactor have been implemented by developing countries such as Germany, USA and the United Kingdom using the anaerobic digestion (AD) process. In Thailand, biohythane production in a two-stage process has been widely studied. However, in Malaysia, treating organic and agricultural wastes using an integrated system of dark fermentation (DF) coupled with anaerobic digestion (AD) is scarce. For instance, in most oil palm mills, palm oil mill effluent (POME) is treated using a conventional open-ponding system or closed-digester tank for biogas capture. This paper reviewed relevant literature studies on treating POME and other organic wastes using integrated bioreactor implementing DF and/or AD process for biohydrogen and/or biomethane production. Although the number of papers that have been published in this area is increasing, a further review is needed to reveal current technology used and its benefits, especially in Malaysia, since Malaysia is the second-largest oil palm producer in the world.

The most frequently notified pathogenic microorganisms in the RASFF in 1980–2017 were Salmonella sp., Listeria, Escherichia and Vibrio, whereas, among the notified non-pathogenic microorganisms were unspecified microorganisms, Enterobacteriaceae, Salmonella sp. and Coliforms. Microorganisms were reported mainly in poultry meat, meat, fish, molluscs, crustaceans, fruits, vegetables, herbs, spices, nuts, milk, cereals (in food) and in feed materials and pet food (in feed). The number of notifications decreased at the turn of 2005 and 2006, but has steadily increased since then. The notification basis were official controls, border controls and company’s checks. Products were notified mainly by Italy, France, United Kingdom, Germany and Netherlands. The reported products originated from Brazil, European Union countries and India, Thailand and Vietnam. The notification types were alerts, information and border rejections. The distribution status was often not specified or distribution on the market was possible. The risk decision was usually not made. Products were re-dispatched, import was not authorised or products were withdrawn from the market, destroyed and recalled from the market. Proper cooperation within the framework of the RASFF can contribute to shaping public health law and reducing outbreaks associated with microorganisms. Full article

Religion has been profoundly reconfigured in the age of development. Over the past half century, we can trace broad transformations in the understandings and experiences of religion across traditions in communities in many parts of the world. In this paper, we delineate some of the specific ways in which ‘religion’ and ‘development’ interact and mutually inform each other with reference to case studies from Buddhist Thailand and Muslim Indonesia. These non-Christian cases from traditions outside contexts of major western nations provide windows on a complex, global history that considerably complicates what have come to be established narratives privileging the agency of major institutional players in the United States and the United Kingdom. In this way we seek to move discussions toward more conceptual and comparative reflections that can facilitate better understandings of the implications of contemporary entanglements of religion and development.
