Nudge strategies for behavior-based prevention and control of neglected tropical diseases: A scoping review and ethical assessment.

BACKGROUND: Nudging, a strategy that uses subtle stimuli to direct people's behavior, has recently been included as an effective and low-cost behavior change strategy in low- and middle- income countries (LMIC), targeting behavior-based prevention and control of neglected tropical diseases (NTDs). The present scoping review aims to provide a timely overview of how nudge interventions have been applied within this field. In addition, the review proposes a framework for the ethical consideration of nudges for NTD prevention and control, or more broadly global health promotion. METHODS: A comprehensive search was performed in several databases: MEDLINE, PsycINFO, and Embase (Ovid), Web of Science Core Collection, CINAHL, ERIC and Econ.Lit (EBSCO), as well as registered trials and reviews in CENTRAL and PROSPERO to identify ongoing or unpublished studies. Additionally, studies were included through a handpicked search on websites of governmental nudge units and global health or development organizations. RESULTS: This scoping review identified 33 relevant studies, with only two studies targeting NTDs in particular, resulting in a total of 67 nudge strategies. Most nudges targeted handwashing behavior and were focused on general health practices rather than targeting a specific disease. The most common nudge strategies were those targeting decision assistance, such as facilitating commitment and reminder actions. The majority of nudges were of moderate to high ethical standards, with the highest standards being those that had the most immediate and significant health benefits, and those implemented by agents in a trust relationship with the target audience. CONCLUSION: Three key recommendations should inform research investigating nudge strategies in global health promotion in general. Firstly, future efforts should investigate the different opportunities that nudges present for targeting NTDs in particular, rather than relying solely on integrated health promotion approaches. Secondly, to apply robust study designs including rigorous process and impact evaluation which allow for a better understanding of 'what works' and 'how it works'. Finally, to consider the ethical implications of implementing nudge strategies, specifically in LMIC.

Parasites! Graphic Exploration of Tropical Disease Drug Development.

Parasites!, a 2010 comic sponsored by the Wellcome Trust Centre for Molecular Parasitology, demonstrates that a graphic narrative can play a role in energizing public debate. Part of the genre known as graphic medicine-comics about illness, treatment, disability, and caregiving-Parasites! is intended to educate readers of all ages about illnesses less known in the developed world. Two visual strategies in particular enable the comic to offer an alternative and aesthetic response to questions about developing drugs to treat tropical diseases for profit. By including visuals and text, and not just one of these formats, viewers must reorient themselves aesthetically and epistemologically to ethical, social, cultural, and political structures that adversely affect human health.

How to deal with neglected tropical diseases in the light of an African ethic.

Many countries in Africa, and more generally those in the Global South with tropical areas, are plagued by illnesses that the wealthier parts of the world (mainly 'the West') neither suffer from nor put systematic effort into preventing, treating or curing. What does an ethic with a recognizably African pedigree entail for the ways various agents ought to respond to such neglected diseases? As many readers will know, a characteristically African ethic prescribes weighty duties to aid on the part of those in a position to do so, and it therefore entails that there should have been much more contribution from the Western, 'developed' world. However, what else does it prescribe, say, on the part of sub-Saharan governments and the African Union, and are they in fact doing it? I particularly seek to answer these questions here, by using the 2013-16 Ebola crisis in West Africa to illustrate what should have happened but what by and large did not.

Ethical issues in funding research and development of drugs for neglected tropical diseases.

Neglected and tropical diseases, pervasive in developing countries, are important contributors to global health inequalities. They remain largely untreated due to lack of effective and affordable treatments. Resource-poor countries cannot afford to develop the public health interventions needed to control neglected diseases. In addition, neglected diseases do not represent an attractive market for pharmaceutical industry. Although a number of international commitments, stated in the Millennium Development Goals, have been made to avert the risk of communicable diseases, tropical diseases still remain neglected due to delays in international assistance. This delay can be explained by the form international cooperation has generally taken, which is limited to promoting countries' national interests, rather than social justice at a global level. This restricts the international responsibility for global inequalities in health to a humanitarian assistance. We propose an alternative view, arguing that expanding the scope of international cooperation by promoting shared health and economic value at a global level will create new opportunities for innovative, effective and affordable interventions worldwide. It will also promote neglected diseases as a global research priority. We build our argument on a proposal to replace the patenting system that currently regulates pharmaceutical research with a global fund to reward this research based on actual decreases in morbidity and mortality at a global level. We argue that this approach is beneficent because it will decrease global health inequalities and promote social justice worldwide.

[Medical ethics and cultures of the world]. / Ethique médicale et cultures du monde.

We celebrate the anniversary of the Société de Pathologie exotique, founded in 1908. Is the term exotic still appropriate to single out a kind of pathology, in the era of Globalization? And what is the meaning of labeling different sets of ethical values, some of which can be said exotic, with the legitimate purpose of acknowledging, on an equal footing, the irreducible differences among cultures? Further research often reveals behind the so-called pluralism of values the socio-economic inequalities, which explain disparities. "Exotic" indicates a crying need for more in-depth analysis of medical practices in all countries, including Western ones, and an alternating close and remote look at all of them, in order to display "a rainbow of values on an ethical horizon".
