Impact of Three Years Training on Operations Capacities of Research Ethics Committees in Nigeria

This paper describes a three‐year project designed to build the capacity of members of research ethics committes to perform their roles and responsibilities efficiently and effectively. The project participants were made up of a cross‐section of the membership of 13 Research Ethics Committees (RECs) functioning in Nigeria. They received training to develop their capacity to evaluate research protocols, monitor trial implementation, provide constructive input to trial staff, and assess the trial's success in promoting community engagement in the research. Following the training, technical assistance was provided to participants on an ongoing basis and the project's impacts were assessed quantitatively and qualitatively. Results indicate that sustained investment in capacity building efforts (including training, ongoing technical assistance, and the provision of multiple tools) improved the participants’ knowledge of both the ethical principles relevant to biomedical research and how effective REC should function. Such investment was also shown to have a positive impact on the knowledge levels of other RECs members (those who did not receive training) and the overall operations of the RECs to which the participants belonged. Building the capacity of REC members to fulfill their roles effectively requires sustained effort and investment and pays off by enabling RECs to fulfill their essential mission of ensuring that trials are conducted safely and ethically.     

Research ethics capacity development in Africa: exploring a model for individual success

The Johns Hopkins-Fogarty African Bioethics Training Program (FABTP) has offered a fully-funded, one-year, non-degree training opportunity in research ethics to health professionals, ethics committee members, scholars, journalists and scientists from countries across sub-Saharan Africa. In the first 9 years of operation, 28 trainees from 13 African countries have trained with FABTP. Any capacity building investment requires periodic critical evaluation of the impact that training dollars produce. In this paper we describe and evaluate FABTP and the efforts of its trainees. Our data show that since 2001, the 28 former FABTP trainees have authored or co-authored 105 new bioethics-related publications; were awarded 33 bioethics-related grants; played key roles on 78 bioethics-related research studies; and participated in 198 bioethics workshops or conferences. Over the past nine years, trainees have collectively taught 48 separate courses related to bioethics and have given 170 presentations on various topics in the field. Many former trainees have pursued and completed doctoral degrees in bioethics; some have become editorial board members for bioethics journals. Female trainees were, on average, less experienced at matriculation and produced fewer post-training outputs than their male counterparts. More comprehensive studies are needed to determine the relationships between age, sex, previous experience and training program outputs.     

Dilemmas in international research and the value of practical wisdom

When conducting research in an international setting, in a country different than that of the researcher, unpredictable circumstances can arise. A study conducted by a novice North American researcher with a vulnerable population in northern Ghana highlights these happenings with an emphasis placed on the ethical challenges encountered. An illustration from the research is used to highlight an ethical dilemma while in the field, and how utilizing a moral decision‐making framework can assist in making choices about a participant's right to autonomy, privacy, and confidentiality during the research process. Moral frameworks, however, can never be enough to solve a dilemma since guidelines only describe what to aim for and not how to interpret or use them. Researchers must therefore strive to move beyond these frameworks to employ practical wisdom or phronesis so to combine the right thing to do with the skill required to figure out what the right choice is. The skill of practical wisdom must be acquired because without it international researchers indecisively fumble around with good intentions, often leaving a situation in worse shape than they found it.     

Investigating assumptions of vulnerability: A case study of the exclusion of psychiatric inpatients as participants in genetic research in low‐ and middle‐income contexts

Psychiatric genetic research investigates the genetic basis of psychiatric disorders with the aim of more effectively understanding, treating, or, ultimately, preventing such disorders. Given the challenges of recruiting research participants into such studies, the potential for long‐term benefits of such research, and seemingly minimal risk, a strong claim could be made that all non‐acute psychiatric inpatients, including forensic and involuntary patients, should be included in such research, provided they have capacity to consent. There are tensions, however, regarding the ethics of recruiting psychiatric inpatients into such studies. In this paper our intention is to elucidate the source of these tensions from the perspective of research ethics committee interests and decision‐making. We begin by defining inpatient status and outline some of the assumptions surrounding the structures of inpatient care. We then introduce contemporary conceptions of vulnerability, including Florencia Luna’s account of vulnerability which we use as a framework for our analysis. While psychiatric inpatients could be subject to consent‐related vulnerabilities, we suggest that a particular kind of exploitation‐related vulnerability comes to the fore in the context of our case study. Moreover, a subset of these ethical concerns takes on particular weight in the context of genetic research in low‐ and middle‐income countries. At the same time, the automatic exclusion of inpatients from research elicits justice‐related vulnerabilities.     

CULTURE AND GENETIC SCREENING IN AFRICA

Africa is a continent in transition amidst a revival of cultural practices. Over previous years the continent was robbed of the benefits of medical advances by unfounded cultural practices surrounding its cultural heritage. In a fast moving field like genetic screening, discussions of social and policy aspects frequently need to take place at an early stage to avoid the dilemma encountered by Western medicine. This paper, examines the potential challenges to genetic screening in Africa. It discusses how cultural practices may affect genetic screening. It views genomics science as a culture which is trying to diffuse into another one. It argues that understanding the existing culture will help the diffusion process. The paper emphasizes the importance of genetic screening for Africa, by assessing the current level of burden of diseases in the continent and shows its role in reducing disease prevalence. The paper identifies and discusses the cultural challenges that are likely to confront genetic screening on the continent, such as the worldview, rituals and taboos, polygyny, culture of son preference and so on. It also discusses cultural practices that may promote the science such as inheritance practices, spouse selection practices and naming patterns. Factors driving the cultural challenges are identified and discussed, such as socialization process, patriarchy, gender, belief system and so on. Finally, the paper discusses the way forward and highlights the ethical considerations of doing genetic screening on the continent. However, the paper also recognizes that African culture is not monolithic and therefore makes a case for exceptions.     

Maintaining Research Integrity While Balancing Cultural Sensitivity: A Case Study and Lessons From the Field

Contemporary emphasis on creating culturally relevant and context specific knowledge increasingly drives researchers to conduct their work in settings outside their home country. This often requires researchers to build relationships with various stakeholders who may have a vested interest in the research. This case study examines the tension between relationship development with stakeholders and maintaining study integrity, in the context of potential harms, data credibility and cultural sensitivity. We describe an ethical breach in the conduct of global health research by a arising from the ad‐hoc participation of a community stakeholder external to the visiting research group. A framework for reflection is developed from a careful examination of underlying factors and presented with a discussion of consequences and mitigation measures. This framework aims to present lessons learned for researchers working abroad who might face similar situations in their work.     

Off‐Shoring Clinical Research: Exploitation and the Reciprocity Constraint

The last 20 years have seen a staggering growth in the practice of off‐shoring clinical research to low‐and middle‐income countries (LICs and MICs), a growth that has been matched by the neoliberal policies adopted by host countries towards attracting trials to their shores. A recurring concern in this context is the charge of exploitation, linked to various aspects of off‐shoring. In this paper, I examine Alan Wertheimer's approach and offer an alternative view of understanding exploitation in this context. I will suggest that the justification for the enterprise of research is largely dependent on its integration within a health system from which participants regularly benefit and I argue that an attention to a principle of reciprocity will enable us to better recognize and address exploitation in international research.     

Putting placebo‐controlled trials in developing countries to the interpersonal justifiability test

This paper considers the ethics of placebo‐controlled trials in developing countries, where a treatment already exists but is not available due to the low local standard of care. Such trials would not be permitted in more developed nations where a higher standard of care is available. I argue that there are moral intuitions against such trials, but a further intuition that if the trials were aimed at producing treatment options for the developing world, that would be more permissible than if the trials were designed with the benefit of rich world people in mind. An approach based upon GA Cohen's work on interpersonal justifiability is suggested to allow us to explain these intuitions. Cohen's framework shows that these trials are ethically problematic because the inequality in healthcare provision between developing and developed nations that allows them to take place is at least partly the pharmaceutical corporations’ fault. Following Cohen's argument, this means the trials are non‐comprehensively justified. This allows for a more complete explanation of our intuitions than to consider such trials as cases of exploitation, because intuitions on the ethicacy of research can vary even when the exploitation relation remains the same. It is then established that there is good empirical evidence to believe that pharmaceutical corporations do fail the interpersonal justifiability test. The policy implications of this judgement are then considered, and it is suggested that the framework might be equally applicable to examining the permissibility of research conducted on vulnerable people within more developed nations.     

Developing Ethical Awareness in Global Health: Four Cases for Medical Educators

In recent years, the growth of interest in global health among medical students and residents has led to an abundance of short‐term training opportunities in low‐resource environments. Given the disparities in resources, needs and expectations between visitors and their hosts, these experiences can raise complex ethical concerns. Recent calls for best practices and ethical guidelines indicate a need for the development of ethical awareness among medical trainees, their sponsoring and host institutions, and supervising faculty. As a teaching tool to promote this awareness, we developed a scenario that captures many common ethical issues from four different perspectives. Each perspective is presented in case format followed by questions. Taken together, the four cases may be used to identify many of the elements of a well‐designed global health training experience.     

The Challenges of Research Informed Consent in Socio‐Economically Vulnerable Populations: A Viewpoint From the Democratic Republic of Congo

In medical research, the ethical principle of respect for persons is operationalized into the process of informed consent. The consent tools should be contextualized and adapted to the different socio‐cultural environment, especially when research crosses the traditional boundaries and reaches poor communities. We look at the challenges experienced in the malaria Quinact trial, conducted in the Democratic Republic of Congo, and describe some lessons learned, related to the definition of acceptable representative, the role of independent witness and the impact of socio‐economic vulnerability. To ensure children's protection, consent is required by the parents or, in their absence, by a legally mandated representative. In our setting, children's responsibility is often entrusted permanently or temporarily to relatives or friends without a tribunal mandate. Hence, a notion of ‘culturally acceptable representative’ under supervision of the local Ethics Committee may be more suitable. To ensure protection of illiterate subjects, an independent witness is required to confirm that the consent was freely given. However, in low‐literacy contexts, potential witnesses often don't have any previous relationship with patient and there may be power‐unbalance in their relationship, rather than genuine dialogue. In poor communities, trial participation may be seen as an opportunity to secure access to healthcare. Poverty may also lead to ‘competition’ to access the research‐related benefits, with a risk of disturbance at societal or household level. Adjusting consent procedures to sociocultural and socioeconomic realities is essential for fulfilling the underlying ethical principles. This requires a collaborative dialogue between researchers, regulators and ethics committees.     

Against Permitted Exploitation in Developing World Research Agreements

This paper examines the moral force of exploitation in developing world research agreements. Taking for granted that some clinical research which is conducted in the developing world but funded by developed world sponsors is exploitative, it asks whether a third party would be morally justified in enforcing limits on research agreements in order to ensure more fair and less exploitative outcomes. This question is particularly relevant when such exploitative transactions are entered into voluntarily by all relevant parties, and both research sponsors and host communities benefit from the resulting agreements. I show that defenders of the claim that exploitation ought to be permitted rely on a mischaracterization of certain forms of interference as unjustly paternalistic and two dubious empirical assumptions about the results of regulation. The view I put forward is that by evaluating a system of constraints on international research agreements, rather than individual transaction‐level interference, we can better assess the alternatives to permitting exploitative research agreements.     

The Vulnerability of Study Participants in the Context of Transnational Biomedical Research: From Conceptual Considerations to Practical Implications

Outsourcing clinical trials sponsored by pharmaceutical companies from industrialized countries to low‐ (middle)‐income countries – summarized as transnational biomedical research (TBR) – has lead to many concerns about ethical standards. Whether study participants are particularly vulnerable is one of those concerns. However, the concept of vulnerability is still vague and varies in its definition. Despite the fact that important international ethical guidelines such as the Declaration of Helsinki by the World Medical Association or the Ethical Guidelines for Biomedical Research Involving Human Subjects by the Council of International Organizations of Medical Sciences refer to vulnerability as ethical principle, each of their approaches are different. To overcome these shortcomings, we analyze and unite different approaches of vulnerability and develop practical criteria in order to operationalize the concept especially for the context of TBR. These criteria refer to the context of a study as well as the characteristics and the current living situation of study participants. Based on a case study of an HIV‐vaccine‐trial conducted in India we demonstrate how those criteria can be applied in a retrospective way to identify potential ethical conflicts. The criteria can also indicate a prospective function for ethical pre‐assessment. For this, we provide an outlook for three major topics: 1. Vulnerability as a normative concept: Different ways of protection; 2. The relevance of transparency and 3. Vulnerability as an instrument to increase decision participation of human subjects.     

Lessons from the Ebola epidemics and their applications for COVID‐19 pandemic response in sub‐Saharan Africa

COVID‐19, caused by a novel coronavirus named SARS‐CoV‐2, was identified in December 2019, in Wuhan, China. It was first confirmed in sub‐Saharan Africa in Nigeria on 27 February 2020 and has since spread quickly to all sub‐Saharan African countries, causing more than 111,309 confirmed cases and 2,498 deaths as of 03 June 2020. The lessons learned during the recent Ebola virus disease (EVD) outbreaks in some sub‐Saharan African countries were expected to shape and influence the region’s responses to COVID‐19 pandemic. However, some of the challenges associated with the management of the EVD outbreaks persist and create obstacles for the effective management of the COVID‐19 pandemic. This article describes the commonalities between the EVD epidemics and COVID‐19 pandemic, with a view to draw on lessons learned to effectively tackle the ongoing pandemic. Key successes, failures and lessons learned from previous EVD outbreaks are discussed. Recommendations on how these lessons can be translated to strengthen the COVID‐19 response in sub‐Saharan Africa are provided.     

Promoting Research Integrity in Africa: An African Voice of Concern on Research Misconduct and the Way Forward

African researchers and their collaborators have been making significant contributions to useful research findings and discoveries in Africa. Despite evidence of scientific misconduct even in heavily regulated research environments, there is little documented information that supports prevalence of research misconduct in Africa. Available literature on research misconduct has focused on the developed world, where credible research integrity systems are already in place. Public attention to research misconduct has lately increased, calling for attention to weaknesses in current research policies and regulatory frameworks. Africa needs policies, structural and governance systems that promote responsible conduct of research. To begin to offset this relative lack of documented evidence of research misconduct, contributors working in various research institutions from nine African countries agreed to share their experiences to highlight problems and explore the need to identify strategies to promote research integrity in the African continent. The experiences shared include anecdotal but reliable accounts of previously undocumented research misconduct, including some ‘normal misbehavior’ of frontline staff in those countries. Two broad approaches to foster greater research integrity are proposed including promotion of institutional and individual capacity building to instil a culture of responsible research conduct in existing and upcoming research scientist and developing deterrent and corrective policies to minimize research misconduct and other questionable research practices. By sharing these experiences and through the strategies proposed, the authors hope to limit the level of research misconduct and promote research integrity in Africa.     

US IRBs confronting research in the developing world

Increasingly, US‐sponsored research is carried out in developing countries, but how US Institutional Review Boards (IRBs) approach the challenges they then face is unclear. METHODS: I conducted in‐depth interviews of about 2 hours each, with 46 IRB chairs, directors, administrators and members. I contacted the leadership of 60 IRBs in the United States (US) (every fourth one in the list of the top 240 institutions by National Institutes of Health (NIH) funding), and interviewed IRB leaders from 34 (55%). RESULTS: US IRBs face ethical and logistical challenges in interpreting and applying principles and regulations in developing countries, given economic and health disparities, and limited contextual knowledge. These IRBs perceive wide variations in developing world IRBs/RECs' quality, resources and training; and health systems in some countries may have long‐standing practices of corruption. These US IRBs often know little of local contexts, regulations and standards of care, and struggle with understandings of other cultures' differing views of autonomy, and risks and benefits of daily life. US IRBs thus face difficult decisions, including how to interpret principles, how much to pay subjects and how much sustainability to require from researchers. IRB responses and solutions include trying to maintain higher standards for developing world research, obtain cultural expertise, build IRB infrastructure abroad, communicate with foreign IRBs, and ‘negotiate’ for maximum benefits for participants and fearing ‘worst‐case scenarios’. CONCLUSIONS: US and foreign IRBs confront a series of tensions and dilemmas in reviewing developing world research. These data have important implications for increased education of IRBs/RECs and researchers in the US and abroad, and for research and practice.     

Genetic consequences of population expansions and contractions in the common hippopotamus (Hippopotamus amphibius) since the Late Pleistocene

Over the past two decades, an increasing amount of phylogeographic work has substantially improved our understanding of African biogeography, in particular the role played by Pleistocene pluvial–drought cycles on terrestrial vertebrates. However, still little is known on the evolutionary history of semi‐aquatic animals, which faced tremendous challenges imposed by unpredictable availability of water resources. In this study, we investigate the Late Pleistocene history of the common hippopotamus (Hippopotamus amphibius), using mitochondrial and nuclear DNA sequence variation and range‐wide sampling. We documented a global demographic and spatial expansion approximately 0.1–0.3 Myr ago, most likely associated with an episode of massive drainage overflow. These events presumably enabled a historical continent‐wide gene flow among hippopotamus populations, and hence, no clear continental‐scale genetic structuring remains. Nevertheless, present‐day hippopotamus populations are genetically disconnected, probably as a result of the mid‐Holocene aridification and contemporary anthropogenic pressures. This unique pattern contrasts with the biogeographic paradigms established for savannah‐adapted ungulate mammals and should be further investigated in other water‐associated taxa. Our study has important consequences for the conservation of the hippo, an emblematic but threatened species that requires specific protection to curtail its long‐term decline.     

The Social Value of Knowledge and International Clinical Research

In light of the growth in the conduct of international clinical research in developing populations, this paper seeks to explore what is owed to developing world communities who host international clinical research. Although existing paradigms for assigning and assessing benefits to host communities offer valuable insight, I criticize their failure to distinguish between those benefits which can justify the conduct of research in a developing world setting and those which cannot. I argue that the justification for human subjects research is fundamentally grounded in the social value of knowledge, and that this value is context‐dependent in a manner which should inform our ethical evaluation of the conduct of research in specific settings. I propose a new framework for the assessment of research benefits assigned to developing world host communities, a natural implication of which is to limit the types of research projects which may permissibly be conducted in developing world settings.     

Ethics of human genetic studies in sub-saharan Africa: the case of Cameroon through a bibliometric analysis

Many ethical concerns surrounding human genetics studies remain unresolved. We report here the situation in Cameroon. Objectives: To describe the profile of human genetic studies that used Cameroonian DNA samples, with specific focus on i) the research centres that were involved, ii) authorship, iii) population studied, iv) research topics and v) ethics disclosure, with the aim of raising ethical issues that emerged from these studies. Method: Bibliometric Studies; we conducted a PubMed-based systematic review of all the studies on human genetics that used Cameroonian DNA samples from 1989 to 2009. Results and Discussion: Fifty articles were identified, involving predominantly research centres from Europe (64%) and America (32%). Only 7 (14%) Cameroonian institutions and 14 (28%) Cameroonian authors were associated with these publications. At least 52% of publications were devoted to population genetics (variation/migration patterns) amongst 30 Cameroonian ethnic groups. Very few studies concerned public health related genetic issues and only 5 (10%) references were found for hemoglobinopathies like sickle cell anaemia. Almost all DNA samples are 'banked' outside of the African continent. Capacity building, rights to the genetic information and benefits to the individuals, communities and populations who contribute to these studies are addressed. Conclusions: 1) Our data suggests the need for a wider debate towards building capacity and addressing ethical issues related to human genomic research in sub-Saharan Africa and specifically in Cameroon; 2) National ethical guidelines and regulations concerning the collection, use and storage of human DNA are urgently needed in Cameroon.     

Benefit Sharing in a Global Context: Working Towards Solutions for Implementation

Due to the state of globalized clinical research, questions have been raised as to what, if any, benefits those who contribute to research should receive. One model for compensating research participants is “benefit sharing,” and the basic premise is that, as a matter of justice, those who contribute to scientific research should share in its benefits. While incorporated into several international documents for over two decades, benefit sharing has only been sparsely implemented. This analysis begins by addressing the concept of benefit sharing, its historical development, and how it has been applied in the context of virus sharing for influenza research. The second portion of this analysis presents recommendations for ensuring benefit sharing. These recommendations are threefold: 1) an emphasis on social pressure, 2) the revision of international documents as means to ensure benefit sharing, and 3) greater collaboration between sponsor IRB and host country IRB. Because clinical research is a globalized industry, a global model will be proposed in the second that focuses on collaboration between the sponsor and host country. This collaboration is vital in order to ensure that proper forms of benefit sharing are accomplished as a matter of justice.
