Ethical considerations in surgical research conducted in African LMICs: A comprehensive narrative review

Introduction: Surgical research has revolutionized healthcare by improving the efficacy, safety, and efficiency of surgical interventions. This research has the potential to significantly impact healthcare delivery in Africa, where surgical diseases pose a major public health burden. Studies suggest surgery alone could reduce the global disease burden by 11%, with a substantial portion stemming from conditions prevalent in sub-Saharan Africa like traumatic injuries, childbirth complications, and surgical infections. However, conducting surgical research in Africa presents unique ethical challenges. The continent’s diverse socio-economic environments and rich cultural contexts necessitate careful consideration of ethical principles. Traditional research models often don’t translate well to African settings, raising concerns about informed consent, community engagement, and benefit-sharing. Aim: This review aims to shed light on various ethical dilemmas posed within surgical research, conducted in African countries. Further, standard practices and recommendations that involve a multi-pronged approach to mitigate said issues were explored. Materials and Methods: A meticulous analysis of the existing literature pertaining to the ethical issues proffered in Africa was performed. Databases employed comprised PubMed/MEDLINE, Embase, Scopus, and EBSCOhost. Pertinent case studies were also reviewed to comprehend said issues, providing comprehensive recommendations. Results: In addressing the ethical challenges in the research, the importance of resource limitation, sociocultural factors, informed consent barriers, technological obsolescence, training deficits, power dynamics, vulnerable populations, regulatory oversight, and compliance was highlighted. The proposed approaches include conducting focused research lectures and practical workshops on surgery, organizing surgical boot camps for medical students, interns, and residents, promoting research in related fields such as anesthesia, radiology, and pathology, ensuring the presence of on-site surgeons as needed, and arranging outreach surgical and educational camps for patients. Conclusion: Promoting community engagement and training local researchers and surgeons are crucial for navigating the unique ethical landscape in Africa. By prioritizing ethical considerations, surgical research can contribute to improved healthcare outcomes and a more equitable healthcare system across the continent.

Thoughts on the education in measurement and instrumentation: A review of requirements

The paper examines the requirements for new information technology tools for education and training in measurement and instrumentation, given the advances in capability of information technology. A review is presented of the capabilities and limitations of educational tools. It is argued that the requirements are affected by the widening global spread of the application of measurement and instrumentation technology, the increasing importance of the metrological perspective of the discipline, the need for education and training at all levels (not only at the advanced scientific level), and the importance of resource limitation.

Disturbance, habitat structure and the ecology of fishes on coral reefs

Abstract This paper reviews empirical studies relating communities of coral‐reef fishes to the characteristics of the underlying habitat, and the effects of habitat disturbance. Many contrasting patterns in the relationships between fish communities and coral cover, habitat heterogeneity or topographic complexity have been described, including strong effects of particular habitat characteristics (both positive and negative), as well as those finding weak or no relationships. In addition, a whole range of potential responses to different kinds of disturbance, including hurricane damage, crown‐of‐thorns (Acanthaster planci) outbreaks, and El Niño‐associated coral and sea urchin die‐offs, have been described. Few workers have attempted to test among alternative models about the importance of resource limitation or responses to disturbance, so critical hypotheses have not been tested. Potential generalizations may be obscured due to a number of problems faced when making comparisons among existing studies. These include the enormous variation in the magnitude of changes to habitats observed, restrictive assumptions about the form of relationships between fish and habitat variables, inadequate descriptions of habitat and fish community structure, a heavy reliance on ‘natural’, pseudoreplicated experiments and a plethora of different numerical and analytical techniques. We conclude that the search for generalizations would be facilitated by a greater attention to theory and clearer statements of the hypotheses being tested. Evaluation of the general importance of fish‐habitat interactions must await the application of common observational and experimental methodologies to a wider range of fish taxa and locations.
