Bitter Taste Perception in BaYaka Hunter‐Gatherers
Bitter-tasting phenotype differed among BaYaka individuals, with higher proportions of bitter tasters among those born and raised in town compared to those from forest camps. These results suggest that early-life ecological context may contribute towards variation in bitter taste perception, which we hypothesize might be due to differences in exposure to bitter wild plant compounds
Sedentarization and Child Health
Objectives This study evaluates differences in the nutritional status of children under 5 years old among the Bodi (Mela) of southwest Ethiopia, in the context of a sedentarization program which involved resettlement of pastoralist families in government‐designed villages (villagization sites). Methods Data were collected in 2013 from two settings: state‐run villagization sites (Hana), where families were forcibly resettled 6–18 months earlier to…
Achieving equitable access to health technologies during a pandemic
The COVID-19 pandemic underlined stark inequalities in timely access to health technologies worldwide. Universities, by conducting a significant amount of early biomedical research and development, have a critical but often overlooked role in determining downstream equitable access to health technologies. This paper reviews university's policies and practices regarding COVID-19 health technologies in the United Kingdom (UK) during the recent pand…
One Health Wash
While the One Health framework is now widely accepted as a strength in understanding antimicrobial resistance (AMR), its application in intervention design to prevent and control drug-resistant infections across humans, animals, and the environment remains weak. The potential for infection prevention and control measures to contribute to the AMR agenda is recognised in rhetoric, but evidence to guide action is patchy and uncoordinated. While wate…
Global Covid-19 Vaccine Inequity
Within the first year of distribution of vaccines against COVID-19, high-income countries (HICs) have achieved vaccination rates of 75-80%, whilst low-income countries (LICs) vaccinated <10%. This disparity in access has been one of the greatest failures of international cooperation during the SARS-CoV-2 pandemic. Global COVID-19 vaccine inequity affects us all, with ongoing risk of new variants emerging until global herd immunity is strengthened…
University patenting and licensing practices in the United Kingdom during the first year of the Covid-19 pandemic
Universities' decisions during technology transfer may affect affordability, accessibility, and availability of COVID-19 health technologies downstream. We investigated measures taken by the top 35 publicly funded UK universities to ensure global equitable access to COVID-19 health technologies between January and end of October 2020. We sent Freedom Of Information (FOI) requests and analysed universities’ websites, to (i) assess institutional st…
Acoustic regularities in infant-directed speech and song across cultures
Structural violence and the biomedical innovation system
box What is already known? When universities engage in inequitable technology transfer practices, by patenting and exclusively licensing biomedical innovations in ways enabling pricing monopoly formation, they contribute to harmful barriers to access to medicines and other health technologies for millions of people. What are the new findings? Universities are contributing to the violation of the social and economic rights of those unable to acces…
Who funded the research behind the Oxford–AstraZeneca Covid-19 vaccine
OBJECTIVES: The Oxford-AstraZeneca COVID-19 vaccine (ChAdOx1 nCoV-19, Vaxzevira or Covishield) builds on two decades of research and development (R&D) into chimpanzee adenovirus-vectored vaccine (ChAdOx) technology at the University of Oxford. This study aimed to approximate the funding for the R&D of ChAdOx and the Oxford-AstraZeneca vaccine and to assess the transparency of funding reporting mechanisms. METHODS: We conducted a scoping review an…
Making a Covid-19 vaccine that works for everyone
Coronavirus disease 2019 (COVID-19) mortality and morbidity have been shown to increase with deprivation and impact non-White ethnicities more severely. Despite the extra risk Black, Asian and Minority Ethnicity (BAME) groups face in the pandemic, our current medical research system seems to prioritise innovation aimed at people of European descent. We found significant difficulties in assessing baseline demographics in clinical trials for COVID-…
The timing of adrenarche in Maya girls, Merida, Mexico
BACKGROUND: Adrenarche involves maturation of the hypothalamic-pituitary-adrenal axis and increased production of dehydroepiandrosterone and its sulfate ester, dehydroepiandrosterone-sulfate (DHEA-S). It occurs at ages 6 to 8 in industrialized populations, marking the transition from childhood to juvenility and cognitive development at middle childhood. Studies in subsistence level populations indicate a later age (8-9) for adrenarche, but only t…
