Project description:IntroductionIn December 2019, the COVID-19 pandemic highlighted the urgent need for rapid collaboration, research, and interventions. International research collaborations foster more significant responses to rapid global changes by enabling international, multicentre research, decreasing biases, and increasing study validity while reducing overall research time and costs. However, there has been low uptake of collaborative research by African institutions and individuals.AimTo systematically review facilitating factors and challenges to collaborative surgical research studies conducted in Africa.MethodologyA meta-research review using PubMed®/MEDLINE and Embase on surgical collaboration in Africa from 1st of January 2011 to 31st of September 2021 in accordance to PRISMA guidelines. Surgical studies by collaborative groups involving African authors and sites were included (55 papers). Data on the study period, geographical regions, and research scope, facilitating factors, and challenges were extracted from the studies retrieved from the search.ResultsMost of the collaborations in Africa occurred with European institutions (76%). Of the 54 African countries, 63% (34/54) participated in surgical collaborations. The highest collaboration frequency occurred in South Africa (11%) and Nigeria (8%). However, most publications originated from Eastern Africa (43%). Leveraging synergies between high- and low- to middle-income countries (LMICs), well-defined structures, and secure data platforms facilitated collaboration. However, the underrepresentation of collaborators from LMICs was a significant challenge.ConclusionAvailable literature provides critical insights into the facilitating factors and challenges of research collaboration with Africa. However, there is a need for a detailed prospective study to explore the themes highlighted further.Systematic review registrationPROSPERO 2022 CRD42022352115 .

Project description:BACKGROUND AND OBJECTIVES:Children and pregnant women use 75% of the blood supply in sub-Saharan Africa (SSA) but face widespread blood shortages. To increase safe blood supply, Africa-specific evidence and strengthened capacity for transfusion research are needed. Our study analysed seven years of SSA transfusion publications, compared researched topics against priorities and enumerated SSA transfusion research collaborations. MATERIALS AND METHODS:Data on research topic, journal type, authors' institutions and country were extracted from transfusion-related SSA articles published between 2008 and 14 and used to construct a quantitative, graphic visualization of collaborations. Research topics were compared to those identified as priorities for SSA blood services in 2008 and 2015. RESULTS:Of the 2176, 267 articles (average 38/year) met criteria for analysis. They involved 1245 authors, 673 institutions, 59 countries (35 SSA) and 1375 collaborations. About 41% were on transfusion-transmitted infections. About 34% were published in specialist transfusion journals. Only 7% involved exclusively collaborations within SSA. Two of the top fifteen institutions by publication quantity were from outside SSA. CONCLUSION:Despite a general paucity of SSA-relevant transfusion research, Francophone SSA was well-represented. Published research topics are not well matched to SSA research priorities; research on supply, distribution, financing and systems is particularly neglected. The study provides a baseline against which to track any refocusing of research activity to better meet SSA's needs. Transfusion research hubs within and beyond SSA have been identified as a springboard network for expanding SSA transfusion research capacity.

Project description:The replication-competent recombinant vesicular stomatitis virus (rVSV)-based vaccine expressing a Zaire ebolavirus (ZEBOV) glycoprotein was selected for rapid safety and immunogenicity testing before its use in West Africa.We performed three open-label, dose-escalation phase 1 trials and one randomized, double-blind, controlled phase 1 trial to assess the safety, side-effect profile, and immunogenicity of rVSV-ZEBOV at various doses in 158 healthy adults in Europe and Africa. All participants were injected with doses of vaccine ranging from 300,000 to 50 million plaque-forming units (PFU) or placebo.No serious vaccine-related adverse events were reported. Mild-to-moderate early-onset reactogenicity was frequent but transient (median, 1 day). Fever was observed in up to 30% of vaccinees. Vaccine viremia was detected within 3 days in 123 of the 130 participants (95%) receiving 3 million PFU or more; rVSV was not detected in saliva or urine. In the second week after injection, arthritis affecting one to four joints developed in 11 of 51 participants (22%) in Geneva, with pain lasting a median of 8 days (interquartile range, 4 to 87); 2 self-limited cases occurred in 60 participants (3%) in Hamburg, Germany, and Kilifi, Kenya. The virus was identified in one synovial-fluid aspirate and in skin vesicles of 2 other vaccinees, showing peripheral viral replication in the second week after immunization. ZEBOV-glycoprotein-specific antibody responses were detected in all the participants, with similar glycoprotein-binding antibody titers but significantly higher neutralizing antibody titers at higher doses. Glycoprotein-binding antibody titers were sustained through 180 days in all participants.In these studies, rVSV-ZEBOV was reactogenic but immunogenic after a single dose and warrants further evaluation for safety and efficacy.

Project description:Introduction and methodAfrica is currently host to a number of international genomics research and biobanking consortia, each with a mandate to advance genomics research and biobanking in Africa. Whilst most of these consortia promise to transform the way international health research is done in Africa, few have articulated exactly how they propose to go about this. In this paper, we report on a qualitative interviewing study in which we involved 17 genomics researchers in Africa. We describe their perceptions and expectations of international genomics research and biobanking initiatives in Africa.ResultsAll interviewees were of the view that externally funded genomics research and biobanking initiatives in Africa, have played a critical role in building capacity for genomics research and biobanking in Africa and in providing an opportunity for researchers in Africa to collaborate and network with other researchers. Whilst the opportunity to collaborate was seen as a benefit, some interviewees stressed the importance of recognizing that these collaborations carry mutual benefits for all partners, including their collaborators in HICs. They also voiced two major concerns of being part of these collaborative initiatives: the possibility of exploitation of African researchers and the non-sustainability of research capacity building efforts. As a way of minimising exploitation, researchers in Africa recommended that genuine efforts be made to create transparent and equitable international health research partnerships. They suggested that this could be achieved through,: having rules of engagement, enabling African researchers to contribute to the design and conduct of international health projects in Africa, and mutual and respectful exchange of experience and capacity between research collaborators. These were identified as hallmarks to equitable international health research collaborations in Africa.ConclusionGenomics research and biobanking initiatives in Africa such as H3Africa have gone some way in defining aspects of fair and equitable research collaborations in Africa. However, they will need to strive at achieving equitable health research collaborations if they truly aim at setting a gold standard for how international health research should be conducted in Africa.

Project description:Scientometrics enables scholars to assess and visualize emerging research trends and hot-spots in the scientific literature from a quantitative standpoint. In the last decades, Africa has nearly doubled its absolute count of scholarly output, even though its share in global knowledge production has dramatically decreased. The still-ongoing COVID-19 pandemic has profoundly impacted the way scholarly research is conducted, published, and disseminated. However, the COVID-19-related research focus, the scientific productivity, and the research collaborative network of African researchers during the ongoing COVID-19 pandemic remain to be elucidated. This study aimed to clarify the COVID-19 research patterns among African researchers and estimate the strength of collaborations and partnerships between African researchers and scholars from the rest of the world during the COVID-19 pandemic, collecting data from electronic scholarly databases such as Web of Science (WoS), PubMed/MEDLINE and African Journals OnLine (AJOL), the largest and prominent platform of African-published scholarly journals. We found that COVID-19-related collaboration patterns varied among African regions. For instance, most of the scholarly partnerships occurred with formerly colonial countries (such as European or North-American countries). In other cases, scholarly ties of North African countries were above all with the Kingdom of Saudi Arabia. In terms of number of publications, South Africa and Egypt were among the most productive countries. Bibliometrics and, in particular, scientometrics can help scholars identify research areas of particular interest, as well as emerging topics, such as the COVID-19 pandemic. With a specific focus on the still-ongoing viral outbreak, they can assist decision- and policy-makers in allocating funding and economic-financial, logistic, organizational, and human resources, based on the specific gaps and needs of a given country or research area.

Project description:Research, collaboration, and knowledge exchange are critical to global efforts to tackle antimicrobial resistance (AMR). Different healthcare economies are faced with different challenges in implementing effective strategies to address AMR. Building effective capacity for research to inform AMR-related strategies and policies is recognised as an important contributor to success. Interdisciplinary, intersector, as well as international collaborations are needed to span global to local efforts to tackle AMR. The development of reciprocal, long-term partnerships between collaborators in high-income and in low- and middle-income countries (LMICs) needs to be built on principles of capacity building. Using case studies spanning local and international research collaborations to codesign, implement, and evaluate strategies to tackle AMR, we have evaluated and build upon the ESSENCE criteria for capacity building in LMICs. The first case study describes the local codesign and implementation of antimicrobial stewardship (AMS) in the state of Kerala in India. The second case study describes an international research collaboration investigating AMR surgical patient pathways in India, the UK, and South Africa. We describe the steps undertaken to develop robust, agile, and flexible AMS research and implementation teams. Notably, investing in capacity building ensured that the programmes described in these case studies were sustained through the current severe acute respiratory syndrome coronavirus pandemic. Describing the strategies adopted by a local and an international collaboration to tackle AMR, we provide a model for capacity building in LMICs that can support sustainable and agile AMS programmes.

Project description:The west Africa Ebola virus disease (EVD) epidemic was extraordinary in scale. Now that the epidemic has ended, it is a relevant time to examine published studies with direct relevance to clinical care and, more broadly, to examine the implications of the clinical research response mounted. Clinically relevant research includes literature detailing risk factors for and clinical manifestations of EVD, laboratory and other investigation findings in patients, experimental vaccine and therapeutic clinical trials, and analyses of survivor syndrome. In this Review, we discuss new insights from patient-oriented research completed during the west Africa epidemic, identify ongoing knowledge gaps, and suggest priorities for future research.

Project description:The 2014-2015 Ebola epidemic affected several African countries, claiming more than 11,000 lives and leaving thousands with ongoing sequelae. Safe and effective vaccines could prevent or limit future outbreaks. The recombinant vesicular stomatitis virus-vectored Zaire Ebola (rVSV-ZEBOV) vaccine has shown marked immunogenicity and efficacy in humans but is reactogenic at higher doses. To understand its effects, we examined plasma samples from 115 healthy volunteers from Geneva who received low-dose (LD) or high-dose (HD) vaccine or placebo. Fifteen plasma chemokines/cytokines were assessed at baseline and on days 1, 2 to 3, and 7 after injection. Significant increases in monocyte-mediated MCP-1/CCL2, MIP-1β/CCL4, IL-6, TNF-α, IL-1Ra, and IL-10 occurred on day 1. A signature explaining 68% of cytokine/chemokine vaccine-response variability was identified. Its score was higher in HD versus LD vaccinees and was associated positively with vaccine viremia and negatively with cytopenia. It was higher in vaccinees with injection-site pain, fever, myalgia, chills, and headache; higher scores reflected increasing severity. In contrast, HD vaccinees who subsequently developed arthritis had lower day 1 scores than other HD vaccinees. Vaccine dose did not influence the signature despite its influence on specific outcomes. The Geneva-derived signature associated strongly (ρ = 0.97) with that of a cohort of 75 vaccinees from a parallel trial in Lambaréné, Gabon. Its score in Geneva HD vaccinees with subsequent arthritis was significantly lower than that in Lambaréné HD vaccinees, none of whom experienced arthritis. This signature, which reveals monocytes' critical role in rVSV-ZEBOV immunogenicity and safety across doses and continents, should prove useful in assessments of other vaccines.

Project description:BackgroundInternational collaboration (IC) is essential for the advance of stem cell research, a field characterized by marked asymmetries in knowledge and capacity between nations. China is emerging as a global leader in the stem cell field. However, knowledge on the extent and characteristics of IC in stem cell science, particularly China's collaboration with developed economies, is lacking.Methods and findingsWe provide a scientometric analysis of the China-Canada collaboration in stem cell research, placing this in the context of other leading producers in the field. We analyze stem cell research published from 2006 to 2010 from the Scopus database, using co-authored papers as a proxy for collaboration. We examine IC levels, collaboration preferences, scientific impact, the collaborating institutions in China and Canada, areas of mutual interest, and funding sources. Our analysis shows rapid global expansion of the field with 48% increase in papers from 2006 to 2010. China now ranks second globally after the United States. China has the lowest IC rate of countries examined, while Canada has one of the highest. China-Canada collaboration is rising steadily, more than doubling during 2006-2010. China-Canada collaboration enhances impact compared to papers authored solely by China-based researchers This difference remained significant even when comparing only papers published in English.ConclusionsWhile China is increasingly courted in IC by developed countries as a partner in stem cell research, it is clear that it has reached its status in the field largely through domestic publications. Nevertheless, IC enhances the impact of stem cell research in China, and in the field in general. This study establishes an objective baseline for comparison with future studies, setting the stage for in-depth exploration of the dynamics and genesis of IC in stem cell research.

Project description:BackgroundDigital innovations in medicine are disruptive technologies that can change the way diagnostic procedures and treatments are delivered. Such innovations are typically designed in teams with different disciplinary backgrounds. This paper concentrates on 2 interdisciplinary research teams with 20 members from the medicine and engineering sciences working jointly on digital health solutions.ObjectiveThe aim of this paper was to identify factors on the individual, team, and organizational levels that influence the implementation of interdisciplinary research projects elaborating on digital applications for medicine and, based on the results, to draw conclusions for the proactive design of the interdisciplinary research process to make these projects successful.MethodsTo achieve this aim, 2 interdisciplinary research teams were observed, and a small case study (response rate: 15/20, 75%) was conducted using a web-based questionnaire containing both closed and open self-report questions. The Spearman rank correlation coefficient was calculated to analyze the quantitative data. The answers to the open-ended questions were subjected to qualitative content analysis.ResultsWith regard to the interdisciplinary research projects investigated, the influencing factors of the three levels presented (individual, team, and organization) have proven to be relevant for interdisciplinary research cooperation.ConclusionsWith regard to recommendations for the future design of interdisciplinary cooperation, management aspects are addressed, that is, the installation of a coordinator, systematic definition of goals, required resources, and necessary efforts on the part of the involved interdisciplinary research partners. As only small groups were investigated, further research in this field is necessary to derive more general recommendations for interdisciplinary research teams.Trial registrationGerman Clinical Trials Register, DRKS00023909, https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00023909 ; German Clinical Trials Register, DRKS00025077, https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00025077.
