Posted 27/07/2021. This qualitative study by Mira Schneiders and colleagues discusses the important nutrition-related roles and responsibilities of grandparents caring for grandchildren in rural Cambodian ‘skip-generation’ households. Grandparents appear highly motivated to improve grandchildren’s health and nutrition, but lack necessary resources, leading to frequent moral dilemmas and ethical trade-offs. Interventions to improve child health and nutrition should be designed to be inclusive of older caregivers.
Posted 16/07/2021. Severe metabolic acidosis and acute kidney injury are major causes of mortality in children with severe malaria but are often underdiagnosed in low resource settings. What prognostic factors are associated with severe metabolic acidosis and uraemia in African children with severe falciparum malaria? Secondary analysis of a randomized trial by Mavuto Mukaka and colleagues
Posted 07/07/2021. Frank Smithuis and colleagues conducted a large cluster randomized evaluation of mass drug administration (MDA) with dihydroartemisinin-piperaquine for malaria elimination in an area with high artemisinin resistant Plasmodium falciparum. MDA was a safe and effective tool to accelerate P. falciparum elimination, alongside routine community-based malaria control measures. It was well tolerated and well accepted. MDA did not select for drug resistant parasites.
Posted 06/07/2021. Surveillance of Antimicrobial resistance (AMR) is important in generating evidence to support efforts in controlling the infection. Cherry Lim and colleagues discuss the strengths, potential sources of bias, and challenges of routine microbiology data and different surveillance strategies and solutions used in low- and middle-income countries. Areas requiring support and improvement are highlighted.
Posted 29/06/2021. Frank Smithuis and colleagues describe a cluster of 29 children with severe, painful bone deformities living in very remote Nagaland, northwest Myanmar. They had low 25-hydroxyvitamin D, elevated parathyroid hormone, and elevated alkaline phosphatase levels, consistent with nutritional rickets secondary to vitamin D deficiency, calcium deficiency, or a combination of both. After treatment with vitamin D3 and calcium carbonate, we saw significant improvement in symptoms, biochemistry, and radiography. This is the first report of nutritional rickets in Myanmar in over 120 years.
Posted 23/06/2021. In an RCT of three artemisinin-based combination therapies in pregnancy on the Thailand-Myanmar border where artemisinin resistance is widespread, only dihydroartemisinin-piperaquine provided satisfactory efficacy for P. falciparum, in this study by Makoto Saito & colleagues. Mefloquine-artesunate provided the longest recurrence-free period for P. vivax. Vivax recurrence was so common, chloroquine prophylaxis is warranted after malaria of any species.
Posted 16/06/2021. The progress made in treatment of malaria is threatened by the emergence of resistance to current first line treatments artemisinin-based combination therapies (ACTs). There are currently no good alternatives for the treatment of uncomplicated malaria in the African setting in the event of resistance emerging to antimalarials that are in the ACTs. Mainga Hamaluba, Rob van der Pluijm and colleagues demonstrate that triple artemisinin combination therapies (TACTs) can potentially be used safely to prevent, delay or manage uncomplicated malaria in our setting.
Posted 15/06/2021. Plasmodium vivax caused an estimated 14 million malaria cases in 2017. By collating economic and epidemiological data, Angela Devine and colleagues estimated an economic cost of $359 million associated with these episodes. A scenario analysis explored how costs might change with global access to safe radical cure, estimating cost savings of $17-93 million.
Posted 11/06/2021. Burkholderia pseudomallei, a bacterium found in soil, can cause melioidosis, a potentially fatal disease. Melioidosis was first described in Myanmar but rarely reported over the past decades due to lack of awareness and limited diagnostic facilities. Frank Smithuis and colleagues report a widespread distribution of the organism in Myanmar soil. This should alert clinicians to consider melioidosis as a potential cause of sepsis, pneumonia or abscesses.
Posted 25/05/2021. Seeking treatment including antibiotics without prescription at drug shops is a common practice in Nepal which can contribute to rising antibiotic resistance. This may leave us without effective antibiotics for future infections. In this study, Bipin Adhikari and colleagues explore why people buy antibiotics over the counter in Nepal and implications for its control.
Posted 18/05/2021. Rose McGready and colleagues show a strong association between P. falciparum infection and hypertension, in a large prospective cohort of women followed from the first trimester of pregnancy. Falciparum malaria which sequesters in the placenta most likely drives the development of chronic placental hypoxia, eventually progressing to clinical gestational hypertension or pre-eclampsia. This is important given hypertension is in the top 3 killers of pregnant women and that most pregnancy related hypertensive deaths occur in sub-Saharan Africa where malaria prevention strategies are not implemented until the beginning of second trimester or later.
Posted 14/05/2021. Cryptococcal meningitis is a common serious HIV-associated infection, responsible for 15% of AIDS related deaths globally. Patients are usually treated as in-patients. Frank Smithuis and colleagues reviewed 76 patients treated with amphotericin and fluconazole as out-patients in primary care clinics in Yangon, Myanmar. One-year survival (86%) was higher than existing hospital-based treatment studies and 1029 hospitals days were saved.
Posted 05/05/2021. On the Thailand-Myanmar border, 39% of migrant women and 47% of refugee women experience maternal depression. Gracia Fellmeth and colleagues show that among migrant women, higher levels of social support are associated with lower depression. The perinatal period offers a valuable opportunity to ask women about depression and support networks and offer help to those who need it.
Posted 11/05/2021. Microbiology laboratory data management is complex and is a rate-limiting step for AMR surveillance in low- and middle-income countries. Paul Turner, Liz Ashley, and colleagues summarise the urgent IT infrastructure requirements needed to ensure that the substantial ongoing efforts to develop capacity for AMR surveillance in LMICs realise their full potential.
Posted 07/05/2021. Multidrug-resistant tuberculosis (MDR-TB) remains a significant burden in the Southeast Asia region. Using mathematical modelling approach, Wirichada Pan-Ngum and colleagues assessed the population-level impacts of short-course MDR-TB treatment compared to the conventional therapy. Early initiation of treatment and good level of treatment eligibility are identified to be important determinants to the success of MDR-TB control programmes.
Posted 30/04/2021. In many low- and middle-income countries febrile children are managed by health workers with limited training, in settings where referrals can confer substantial costs and risks. Spot Sepsis, a multi-centre study being implemented by MORU and MSF, aims to develop a practical prognostic tool to help community healthcare providers identify febrile children who may benefit from referral for facility-based medical care.
Posted 16/04/2021. This systematic review by Arjun Chandna and colleagues identified clinical and laboratory prognostic factors, measured at the point of presentation, that can help identify children at risk of severe febrile illness. Most studies included only hospitalised children and further work is required to identify the best predictors to build data-driven triage tools for use by community healthcare providers.
Posted 27/04/2021. The complete treatment of vivax malaria requires a radical cure with a course of 8-aminoquinolines. Bipin Adhikari and colleagues interviewed policymakers in Asia why the radical cure is currently so poorly implemented and what can be done to improve the uptake of the radical cure.
Posted 21/04/2021. Tobias Brummaier and colleagues report a high burden of soil-transmitted helminth infections and an association with maternal anaemia in pregnant migrant and refugee women on the Thai-Myanmar border. Whether the protective effect of Ascaris lumbricoides infection against miscarriage observed in this retrospective dataset results from helminth immune modulation remains to be determined.
Posted 20/04/2021. Artemisinin-based combination therapy (ACT) is the first-line treatment for uncomplicated falciparum malaria, but the ACT drugs are starting to fail. Triple artemisinin-based combination therapy (TACT) is being studied to replace ACTs. In this paper, Phaik Yeong Cheah and colleagues discuss the most important ethical and practical considerations in the potential deployment of TACT.

World Immunization Week highlights the role vaccinations play in improving the health of communities. As the COVID pandemic continues to impact countries worldwide, governments are facing challenges related to coverage, equity and sustainability of routine immunisation alongside access and the particular maintenance requirements related to the SARS-CoV-2 vaccines. Communication with communities has been key to ensure continued engagement with the vaccine programs despite the challenges of current contexts.
For World Malaria Day 2021, F1000 Research Blog spoke to Professor Phaik Yeong Cheah about her research focussed on drama and arts-based community engagement for malaria research, published with Wellcome Open Research.
KWTRP initial community and public engagement strategy was developed in 2005 with three goals: build understanding and trust between researchers and communities, enhance ethical conduct of research, and disseminate research findings to promote uptake into policy. Our programme has since developed and now includes engagement with media, radio programme, media engagement workshops, various meetings and forums, and a fully-fledged school engagement programme that was awarded the 2019 Oxford VC Public Engagement with Research Award.
