Training local Karen and Burman women as skilled birth attendants in refugee settings resulted in no adverse perinatal outcomes and many positive outcomes such as a drop in stillbirths and infant deaths and more babies being born in clinics rather than at home, says a new study published in the scientific journal PLOS ONE.
Posted 15/12/2020. A recent study co-led by Paul Turner and colleagues at COMRU identified extremely high prevalence of antimicrobial resistant (AMR) bacterial carriage in households from Siem Reap, Cambodia. Extended-spectrum beta-lactamase producing Escherichia coli were detected in stool samples from >90% of participants. The results highlight the challenges to AMR control in locations where antibiotic overuse is common.
Posted 04/12/2020. Paul Turner and COMRU researchers, working with Cambodia’s University of Health Sciences and Fondation Merieux, evaluated recently the potential of MALDI-TOF-based serotyping of Streptococcus pneumoniae for vaccine impact surveillance. Despite early promise, the team found that MALDI-TOF performed poorly and should not replace existing serotyping methodologies.
Posted 16/04/2019. Lorenz Von Seidlein and colleagues in Thailand, Myanmar, Vietnam, Cambodia, and Laos explored what happens to malaria transmission when all people residing in a village are treated with antimalarials at the same time, whether they are sick or not. They demonstrated that providing the necessary information is important, but building trust between residents and the team providing the antimalarials is most critical for success.
Posted 09/07/2019. On behalf of the Cambodian Ministry of Health Technical Working Group on Antimicrobial Resistance, Paul Turner and colleagues at COMRU recently led a review of published data on AMR in Cambodia. Significant AMR was identified in a range of priority pathogens although data were limited. On-going national AMR surveillance will address this data gap.
Posted 31/05/2019. Drug-resistant infections caused by Enterobacteriaceae, a family of Gram-negative bacteria, account for a high and increasing disease burden amongst hospitalised neonates in Southeast Asia; carbapenem-resistant strains are particularly important because of limited antibiotic treatment options. Tamalee Roberts and colleagues found that nearly two thirds of infants in a neonatal unit in Thailand became asymptomatic carriers with carbapenem-resistant Enterobacteriaceae during their hospital stays. This work indicates a critical need for interventions to reduce this usually hidden reservoir of drug-resistant bacteria.
Posted 19/02/2019. Germana Bancone and colleagues characterized glucose-6-phosphate dehydrogenase deficiency in over 10 thousand samples collected in 138 villages in Cambodia, Lao PDR, Myanmar, Thailand and Vietnam, showing a country-level prevalence in males ranging from 7.3% to 18.8%. Given this high prevalence, G6PD testing should be carried out in the Greater Mekong Subregion before P. vivax radical cure with 8-aminoquinolines.
Posted 26/03/19. Lorenz Von Seidlein and colleagues wanted to know whether well-resourced mass drug administrations (MDA) can accelerate malaria elimination in the Greater Mekong Subregion. They randomised 16 villages in Myanmar, Vietnam, Cambodia, and Laos to receive MDAs with antimalarial drugs. The intervention had a substantial impact on the prevalence of P. falciparum infections by month 3 after the start of the MDAs. Over the subsequent 9 months, P. falciparum infections returned but stayed below baseline levels.
Posted 07/05/2019. Developed by Paul Turner and fellow members of the Oxford Tropical Network, the MICRO framework provides the scientific community with clear guidance on reporting and interpretation of clinical microbiology and antimicrobial resistance (AMR) data. Use of the framework will result in publication of better quality data for use in the global fight against AMR. The MICRO guideline is also posted on the EQUATOR website www.equator-network.org/reporting-guidelines
Evidence from a new study, initiated by the Primaquine Roll Out Group and conducted at WWARN, supports the World Health Organization (WHO) recommendation for use of 0.25mg/kg dose of primaquine (PQ) combined with artemisinin-based combination therapies (ACT) to block Plasmodium falciparum transmission.
A study to explore the variations of how microscopy methods are reported in published malaria studies has recommended standardised procedures should be implemented for methodological consistency and comparability of clinical trial outcomes.
Blog by Rima Shretta. Preliminary efficacy results from three vaccine candidates currently in Phase 3 trials have shown an efficacy of more than 90% against the development of symptomatic COVID-19. While these results are promising, all vaccines are in relatively early stages of testing. A comprehensive and transparent roadmap is urgently needed, to determine how limited doses of the first vaccines to be licensed will be distributed, together with which groups will initially be prioritized.
A new study quantifying the high risk of Plasmodium vivax parasitaemia after treatment of Plasmodium falciparum malaria aims to identify populations in which a policy of universal radical cure, combining artemisinin-based combination therapy with a hypnozoitocidal antimalarial drug, would be most beneficial.
Dr Clare Ling has been made an honorary Fellow of the Royal College of Pathologists (FRCPath). Currently running Shoklo Malaria Research Unit (SMRU) Microbiology department and supporting the unit’s molecular activities, Clare is a clinical scientist who has worked at SMRU on the Thai-Myanmar border since 2012.
Ethox programme REACH (Resilience, Empowerment and Advocacy in Women's and Children's Health Research) posted a visual research gallery as a Public Engagement project. Six galleries of photos by SMRU's Suphak Nosten depict aspects of migrant workers' daily lives: the Thai-Myanmar border; work; cultural and spiritual values; the often-difficult journeys seeking healthcare; striving for better; and dedicated frontline health workers. Richly coloured, sometimes personal, Suphak’s photography is deeply empathetic and memorable.
