Posted 09/06/2021. Chris Paton and colleagues describe how predictive human-computer interaction (HCI) modelling could be used to improve the safety and usability of digital health systems. We reviewed the history of predictive modelling in HCI and describe how modelling could be integrated with the human-centred design techniques used when developing digital health interventions.
Posted 28/04/2021. While Health and Demographic Surveillance Systems (HDSS) involving verbal autopsy provide essential data on deaths, births and other health-related events in LMICs where alternative sources are limited, Vicki Marsh and colleagues argue that current regulatory frameworks do not sufficiently recognise their nature as a form of non-traditional epidemiological research. Ethical challenges include risks of uncompensated burdens that alternative regulatory approaches may more successfully identify.
Posted 13/04/2021. Self-regulated learning (SRL) remains unexplored for healthcare workers in low-income countries. Tim Tuti, Chris Paton and Niall Winters detail how SRL strategies impact on healthcare providers’ learning gains when using digital learning platforms. We apply Latent Profile Analysis (LPA) to questionnaire responses. We provide insights into the learner factors to consider when implementing technology-mediated learning.
Posted 15/04/2021. Philippe Guérin co-authored a letter published in The Lancet drawing attention of the risk of pooling data from uncomplicated illness and more severe ill hospitalised patients in the development of COVID-19 treatment guidelines. Although SARS-CoV-2 is one virus, the COVID-19 disease has a complex and evolving physiopathology pathway and requires different therapeutic approaches depending of the stage of the disease. In low-resource settings, the prevention of hospital admission is the therapeutic priority.
Posted 31/03/2021. Patient safety is a key goal of WHO but identifying harms and developing strategies to deliver safe care has been given little attention. Mike English and colleague describe a ‘portfolio’ approach to safety improvement in four broad categories: prioritising critical processes, improving the organisation of care, control of risks and enhancing responses to hazardous situations that we believe is relevant to low resource settings. We focus attention on the possible roles of practitioner groups and professional associations as key to advancing patient safety through collaboration and skill development in this field
Posted 22/02/2021. Paper continues to be an important medium for recording inpatient care in low‐ and middle‐income countries. Naomi Muinga and colleagues synthesise evidence on how paper‐based nursing records have been developed within inpatient settings to support documentation of nursing care, and that a human‐centred design approach might better meet users' needs
Posted 16/02/2021. Dexamethasone has been shown to reduce mortality in COVID-19 patients needing oxygen and ventilation by 18% and 36%, respectively. Rima Shretta and colleagues estimate that approximately 12,000 lives could be saved in the UK and 650,000 globally between July-December 2020. Dexamethasone is a cost-effective option with an incremental cost of GBP 940 per life-year gained.
Posted 12/06/2020. Safety of drugs is important, particularly during pregnancy. Makoto Saito and colleagues have pooled the data of 4503 women who had malaria in pregnancy and found that the currently used artemisinin-based combination therapies are equally safe for fetus. This study also highlights that risk of small-for-gestational-age (SGA) is high after malaria in pregnancy even treated with highly efficacious drugs, suggesting that prevention is important for reducing SGA in malaria endemic areas.
Posted 14/04/2020. Enormous emergency efforts are underway to find optimal medical products, to prevent, diagnose, and treat COVID-19, that 7.8 billion people will depend on. With dire disruption of pharmaceutical production and supply and increasing falsified and substandard products, we need strategic planning now to ensure global access to quality-assured medical products and monitoring of supply chains
Posted 02/01/2018. Technological potentials have raised high hopes on healthcare access in LMICs like India. However, five years of research by Dr Marco Haenssgen paint a less optimistic picture and show adverse consequences of mobile phone diffusion, which creates more competition and new divisions and leaves the poorest strata of population worse off than before.
Posted 20/03/2020. 199 patients received standard care, of which 99 received lopinavir-ritonavir for 14 days. Lopinavir-ritonavir didn’t induce significant clinical improvement, and mortality was similar in both groups. However, patients treated with lopinavir-ritonavir spent less time in hospital and in intensive care. The trial enrolled severely ill patients and was not big enough to detect modest benefits. Much larger studies are warranted to confirm or exclude if lopinavir-ritonavir treatment can help.
Posted 12/02/2021. The majority of digital health projects have failed to translate into scaled, routine services, leaving many health leaders cautious and uncertain of how to proceed. Chris Paton and colleagues identify factors that can influence successful and sustainable integration of digital health within local health systems in low resource settings.
Posted 20/02/2018. The malaria parasite is a major cause of illness and deaths throughout the tropics. To survive, the malaria parasite needs to be transmitted by mosquitos form person to person. In this paper Martin Rono and colleagues show at the cellular and molecular level how the parasite balances its investment between growing efficiently in humans and maximising the chances of being transmitted by mosquitos, depending on the local environment.
Posted 12/12/2017. Snakebite envenoming is a neglected tropical disease that kills 100,000 people and maims 400,000 every year. Impoverished populations living in the rural tropics are particularly vulnerable; snakebite envenoming perpetuates the cycle of poverty. Intravenous administration of antivenom is the only specific treatment to counteract envenoming. Confronting snakebite envenoming at a global level demands the implementation of an integrated intervention strategy involving local, national and international organisations.
Posted 05/12/2017. Zika virus RNA is frequently detected in the semen after Zika virus infection. To learn more about persistence of viruses in genital fluids, Dr Alex Salam and Professor Peter Horby searched PubMed and found evidence that 27 viruses can be found in human semen. This may have implications for the risk of sexual transmission, embryonic infection, congenital disease, miscarriage, and infection transmission models.
Posted 28/11/2017. Prabin Dahal reviewed the evolution of statistical methods used to understand and define antimalarial drug efficacy in uncomplicated P. falciparum malaria. The article gives a thorough insight into the historical practices and critically reviews the challenges and limitations associated with current approaches and offers alternative methodologies leading to improved study design and analysis.
Posted 13/10/2017. Professor Peter Horby outlines potential epidemics in Africa. It is difficult to predict when and where new epidemics might occur so we can be better prepared and have a proactive response. This modelling is based on information on each virus as well as governance, communication, infrastructure and health care provision. Some areas remain at high risk and would benefit from improved surveillance, diagnostic capabilities and better health systems and local policies.
Posted 04/10/2017. Melioidosis is a neglected tropical disease estimated to kill 89,000 people a year across tropical regions and a vaccine is urgently required. In this collaboration with Imperial College, Professor Susanna Dunachie report for the first time a link between people with the HLA-B*46 genotype and around a three-fold increased risk of death. Survival from melioidosis is correlated with immune responses to nine key proteins from the causative bacteria, Burkholderia pseudomallei. This gives the foundation for development of an effective vaccine.
Posted 13/09/2017. Amanda Rojek and Peter Horby published a review aimed at clinicians who may treat patients with Ebola Virus Disease. This review outlines advances in understanding the clinical presentation, outcomes and long term sequelae of the disease, and outlines the status of experimental vaccines and treatments.
Posted 22/08/2017. Selecting and trialling therapeutics for preventing congenital Zika disease is challenging. The target product should be low risk, acceptable to the mother, highly effective in preventing adverse fetal outcomes, and practical for widespread clinical use in resource-limited settings. Professor Peter Horby and fellow researchers discuss strategies for addressing these challenges in a recent paper.
The RECOVERY trial was established as a randomised clinical trial to test a range of potential treatments for patients hospitalised with COVID-19. Patients with COVID-19 are at increased risk of blood clots forming in their blood vessels, particularly in the lungs. Between November 2020 and March 2021, the RECOVERY trial included nearly 15,000 patients hospitalised with COVID-19 in an assessment of the effects of aspirin, which is widely used to reduce blood clotting in other diseases. There was no significant difference in the primary endpoint of 28-day mortality
Created in March 2020 to assist policymakers to make use of existing evidence in mathematical and epidemiological models to inform strategies for minimising the impact of COVID-19, the CoMo Consortium brings together mathematical modellers, epidemiologists, health economists and public health experts from more than 40 countries across Africa, Asia and South and North America.
The University of Oxford announces the launch of a centre of global research collaboration and excellence, the Pandemic Sciences Centre. The need for partnership between academic excellence, industry and public health organisations is one of the key lessons learned from the coronavirus pandemic. This centre will unite disciplines, and sectors, to build agile, equitable partnerships that can tackle complex problems and respond to pandemic threats at any time.
Which infections are most common in the Chiangrai region? How should we treat them and how can we improve diagnostic? Which strategies are most effective in directing antibiotic treatment? Blog by Carlo Perrone, research physician based at the Chiang Rai Clinical Research Unit in Chiangrai, Thailand.
Although improvements in child survival globally have been remarkable, 5.2 million children still died in 2019, over half of these in sub-Saharan Africa. A range of factors likely include disparities in childhood immunisations, supplements and breastfeeding practices, antenatal care, skilled birth attendants working in healthcare facilities. Kenya needs to prioritise its child care plans, based on localities and populations with the greatest need. Two KWTRP studies give granular insights into the situation in regions across Kenya.
This large-scale systematic review and meta-analysis aimed to collate all reported serious adverse events in visceral leishmaniasis clinical trials and quantify the incidence of mortality during the first 30 days of therapy. The analyses, which included clinical data from more than 35,000 patients, found that mortality following treatment was an extremely rare event and serious adverse events following treatments were poorly reported.
