Science, medicine and research in the developing world: a perspective

A scoping review on research agendas to enhance prevention of epidemics and pandemics in Africa

Introduction

research is not only needed to prioritise the best possible response during an epidemic and pandemic, it is also understood to be a core pillar of outbreak response. However, few African countries are equipped to perform the needed surveillance and research activities during an outbreak. Therefore, we mapped out research agendas aimed at increased research preparedness towards epidemics or pandemics in Africa.

Methods

eligible studies were searched for in in PubMed, Scopus, and Google Scholar. Additionally, grey literature was sought in Google, citation searches, as well as targeted sites such as the World Health Organization (WHO), Africa Centres for Disease Control and Prevention, African Union, and the Wellcome Trust. Searches were done in March 2020.

Results

the electronic searches yielded 7344 records, of which 34 articles were included in the study. The studies identified around 18 factors highlighted through various research agendas. Majority of the research agendas spoke to general epidemic preparedness and focused largely on understanding virus transmission such as its characteristics and dynamics, and the infrastructure needed to carry out vital research activities.

Conclusion

the review highlights the research needs in order to carry out vital research work but to also bridge knowledge gaps and harmonize outbreak response from key stakeholders. However, Africa needs to create its own health research agendas and capacitate itself to conduct and lead these studies. African health research decisions must center on Africa, with African researchers taking the lead not only on the science produced but ensuring inclusive and equitable involvement from fellow researchers, and in engaging national health ministries as well as the communities.

Health research capacity development in low and middle income countries: reality or rhetoric? A systematic meta-narrative review of the qualitative literature

OBJECTIVES

Locally led health research in low and middle income countries (LMICs) is critical for overcoming global health challenges. Yet, despite over 25 years of international efforts, health research capacity in LMICs remains insufficient and development attempts continue to be fragmented. The aim of this systematic review is to identify and critically examine the main approaches and trends in health research capacity development and consolidate key thinking to identify a more coherent approach.

METHODS

This review includes academic and grey literature published between January 2000 and July 2013. Using a predetermined search strategy, we systematically searched PubMed, hand-searched Google Scholar and checked reference lists. This process yielded 1668 papers. 240 papers were selected based on a priori criteria. A modified version of meta-narrative synthesis was used to analyse the papers.

RESULTS

3 key narratives were identified: the effect of power relations on capacity development; demand for stronger links between research, policy and practice and the importance of a systems approach. Capacity development was delivered through 4 main modalities: vertical research projects, centres of excellence, North-South partnerships and networks; all were controversial, and each had their strengths and weaknesses. A plurality of development strategies was employed to address specific barriers to health research. However, lack of empirical research and monitoring and evaluation meant that their effectiveness was unclear and learning was weak.

CONCLUSIONS

There has been steady progress in LMIC health research capacity, but major barriers to research persist and more empirical evidence on development strategies is required. Despite an evolution in development thinking, international actors continue to use outdated development models that are recognised as ineffective. To realise newer development thinking, research capacity outcomes need to be equally valued as research outputs. While some development actors are now adopting this dedicated capacity development approach, they are in the minority.

H3Africa and the African life sciences ecosystem: building sustainable innovation

Interest in genomics research in African populations is experiencing exponential growth. This enthusiasm stems in part from the recognition that the genomic diversity of African populations is a window of opportunity for innovations in postgenomics medicine, ecology, and evolutionary biology. The recently launched H3Africa initiative, for example, captures the energy and momentum of this interest. This interdisciplinary socio-technical analysis highlights the challenges that have beset previous genomics research activities in Africa, and looking ahead, suggests constructive ways H3Africa and similar large scale science efforts could usefully chart a new era of genomics and life sciences research in Africa that is locally productive and globally competitive. As independent African scholars and social scientists, we propose that any serious global omics science effort, including H3Africa, aiming to build genomics research capacity and capability in Africa, needs to fund the establishment of biobanks and the genomic analyses platforms within Africa. Equally they need to prioritize community engagement and bioinformatics capability and the training of African scientists on these platforms. Historically, the financial, technological, and skills imbalance between Africa and developed countries has created exploitative frameworks of collaboration where African researchers have become merely facilitators of Western funded and conceived research agendas involving offshore expatriation of samples. Not surprisingly, very little funding was allocated to infrastructure and human capital development in the past. Moving forward, capacity building should materialize throughout the entire knowledge co-production trajectory: idea generation (e.g., brainstorming workshops for innovative hypotheses development by African scientists), data generation (e.g., genome sequencing), and high-throughput data analysis and contextualization. Additionally, building skills for political science scholarship that questions the unchecked assumptions of the innovation performers be they funders, scientists, and social scientists, would enable collective innovation that is truly sustainable, ethical, and robust.

Those famous red pills-Deliberations and hesitations. Ethics of placebo use in therapeutic and research settings

Placebo fascinates and mystifies. Even with today's medical science we still do not know how and if it works. The use of placebo both in therapy and in research evokes ethical problems that are not easily resolved either. Placebo is intrinsically linked to deception, while veracity is a basic tenet in today's thinking of a doctor-patient relationship. In research ethics placebo, though considered the golden control condition, leads to the question of the therapeutic obligation. This narrative review presents an overview of these ethical questions and offers considerations that are of relevance to daily medical and research practice both in psychiatry and elsewhere.

International technology transfer of a GCLP-compliant HIV-1 neutralizing antibody assay for human clinical trials

The Collaboration for AIDS Vaccine Discovery/Comprehensive Antibody-Vaccine Immune Monitoring Consortium (CAVD/CA-VIMC) assisted an international network of laboratories in transferring a validated assay used to judge HIV-1 vaccine immunogenicity in compliance with Good Clinical Laboratory Practice (GCLP) with the goal of adding quality to the conduct of endpoint assays for Human Immunodeficiency Virus I (HIV-1) vaccine human clinical trials. Eight Regional Laboratories in the international setting (Regional Laboratories), many located in regions where the HIV-1 epidemic is most prominent, were selected to implement the standardized, GCLP-compliant Neutralizing Antibody Assay for HIV-1 in TZM-bl Cells (TZM-bl NAb Assay). Each laboratory was required to undergo initial training and implementation of the immunologic assay on-site and then perform partial assay re-validation, competency testing, and undergo formal external audits for GCLP compliance. Furthermore, using a newly established external proficiency testing program for the TZM-bl NAb Assay has allowed the Regional Laboratories to assess the comparability of assay results at their site with the results of neutralizing antibody assays performed around the world. As a result, several of the CAVD/CA-VIMC Regional Laboratories are now in the process of conducting or planning to conduct the GCLP-compliant TZM-bl NAb Assay as an indicator of vaccine immunogenicity for ongoing human clinical trials.

A million africans a year dying from cancer by 2030: what can cancer research and control offer to the continent?

In Africa, there were an estimated 681,000 new cancer cases and 512,000 deaths in 2008. Projections to 2030 show a startling rise, with corresponding figures of 1.27 million cases and 0.97 million deaths resulting from population growth and aging alone. The figures make no assumptions about incidence rates which may increase due to the further introduction of tobacco and a more westernized lifestyle. The current situation in many parts of Africa with respect to health care systems suggests that improved cancer treatment would be an insufficient response to this increasing burden. Much could be achieved through cancer prevention by applying current knowledge about major risk factors and the natural history of the disease. For example, vaccination against hepatitis B virus and human papilloma viruses would prevent the occurrence of two of the most common cancers in Africa, liver and cervix, respectively, in the long-term. Strong measures to prevent the widespread introduction of tobacco must be a priority. Early detection and treatment of cervical and breast cancers using approaches applicable now in Africa would provide immediate value, as would the management of human immunodeficiency virus (HIV) infection in respect to HIV-associated malignancies. In parallel, further research is needed into the causes of cancer and the barriers to implementation of promising prevention strategies. Underpinning all is the need for African governments to look forward and prioritize cancer through national cancer control plans, to invest in public health infrastructure and to ensure the adequate training and support for people in cancer prevention and control. Given this core commitment from within Africa, international partners can provide complementary support in a cooperation that permits action now to mitigate the impending tragedy of cancer in the continent of Africa.

Basic science research and education: a priority for training and capacity building in developing countries

This article provides evidence that basic science research and education should be key priorities for global health training, capacity building, and practice. Currently, there are tremendous gaps between strong science education and research in developed countries (the North) as compared to developing countries (the South). In addition, science research and education appear as low priorities in many developing countries. The need to stress basic science research beyond the typical investment of infectious disease basic service and research laboratories in developing areas is significant in terms of the benefits, not only to education, but also for economic strengthening and development of human resources. There are some indications that appreciation of basic science research education and training is increasing, but this still needs to be applied more rigorously and strengthened systematically in developing countries.
