Development of drugs for severe malaria in children

Research ethics in context: understanding the vulnerabilities, agency and resourcefulness of research participants living along the Thai-Myanmar border

BACKGROUND

Research ethics guidelines set a high bar for conducting research with vulnerable populations, often resulting in their exclusion from beneficial research. Our study aims to better characterise participants' vulnerabilities, agency, resourcefulness and sources of support.

METHODS

We undertook qualitative research around two clinical studies involving migrant women living along the Thai-Myanmar border. We conducted 32 in-depth interviews and 10 focus group discussions with research participants, families, researchers and key informants.

RESULTS

We found that being 'undocumented' is at the core of many structural vulnerabilities, reflecting political, economic, social and health needs. Although migrant women lead challenging lives, they have a support network that includes family, employers, community leaders, non-governmental organisations and research networks. Migrant women choose to participate in research to access quality healthcare, gain knowledge and obtain extra money. However, research has the potential to exacerbate existing vulnerabilities, such as the burdens of cross-border travel, foregoing work and being more visible as migrants.

CONCLUSIONS

Our study confirms that research is important to provide evidence-based care and was viewed by participants as offering many benefits, but it also has hidden burdens. Migrant women exercised agency and resourcefulness when navigating challenges in their lives and research participation.

Understanding a science-themed puppet theatre performance for public engagement in Thailand

Background: Fishy Clouds, a 45-minute non-verbal touring puppet theatre show, was created with the objectives of (1) raising awareness of antimicrobial overuse and misuse (the fact that there simply is a problem), (2) raising awareness of the importance of research with children – including those involving antimicrobials, and (3) producing a science-themed performance of entertainment value and high artistic quality. The show used visual storytelling to bring the research and behaviour around antimicrobial resistance (AMR) to life for a broad range of audiences across different ages, locations, levels of education, and language. Methods: In order to understand the effectiveness of Fishy Clouds, we used a realist-informed evaluation approach. A combination of quantitative and qualitative approaches (semi-structured interviews, focus group discussions and field notes) were used for data collection. Results: We received a total of 880 quantitative feedback forms, conducted 22 semi-structured interviews and three focus group discussions. Our data showed that Fishy Clouds was an enjoyable performance to all audience groups and stakeholders and was generally viewed with artistic integrity. However, its effectiveness was primarily in raising existing awareness about medicine use and health more broadly, rather than specific health messaging concerning AMR and research with children. We found that those with limited background on AMR or research with children, such as school children and Karen ethnic migrants exhibited a wide range of interpretations. A science-themed theatre would function better if it is focussed on a single theme, embedded within a programme of activities and conducted at closed venues. Conclusions: Fishy Clouds showed that science theatre events have the potential to support public health programmes and engage local communities in science research.

malERA: An updated research agenda for diagnostics, drugs, vaccines, and vector control in malaria elimination and eradication

Since the turn of the century, a remarkable expansion has been achieved in the range and effectiveness of products and strategies available to prevent, treat, and control malaria, including advances in diagnostics, drugs, vaccines, and vector control. These advances have once again put malaria elimination on the agenda. However, it is clear that even with the means available today, malaria control and elimination pose a formidable challenge in many settings. Thus, currently available resources must be used more effectively, and new products and approaches likely to achieve these goals must be developed. This paper considers tools (both those available and others that may be required) to achieve and maintain malaria elimination. New diagnostics are needed to direct treatment and detect transmission potential; new drugs and vaccines to overcome existing resistance and protect against clinical and severe disease, as well as block transmission and prevent relapses; and new vector control measures to overcome insecticide resistance and more powerfully interrupt transmission. It is also essential that strategies for combining new and existing approaches are developed for different settings to maximise their longevity and effectiveness in areas with continuing transmission and receptivity. For areas where local elimination has been recently achieved, understanding which measures are needed to maintain elimination is necessary to prevent rebound and the reestablishment of transmission. This becomes increasingly important as more countries move towards elimination.

New developments in anti-malarial target candidate and product profiles

A decade of discovery and development of new anti-malarial medicines has led to a renewed focus on malaria elimination and eradication. Changes in the way new anti-malarial drugs are discovered and developed have led to a dramatic increase in the number and diversity of new molecules presently in pre-clinical and early clinical development. The twin challenges faced can be summarized by multi-drug resistant malaria from the Greater Mekong Sub-region, and the need to provide simplified medicines. This review lists changes in anti-malarial target candidate and target product profiles over the last 4 years. As well as new medicines to treat disease and prevent transmission, there has been increased focus on the longer term goal of finding new medicines for chemoprotection, potentially with long-acting molecules, or parenteral formulations. Other gaps in the malaria armamentarium, such as drugs to treat severe malaria and endectocides (that kill mosquitoes which feed on people who have taken the drug), are defined here. Ultimately the elimination of malaria requires medicines that are safe and well-tolerated to be used in vulnerable populations: in pregnancy, especially the first trimester, and in those suffering from malnutrition or co-infection with other pathogens. These updates reflect the maturing of an understanding of the key challenges in producing the next generation of medicines to control, eliminate and ultimately eradicate malaria.
