Tuberculosis treatment intervention trials in Africa: A cross-sectional bibliographic study and spatial analysis

Background Mycobacterium Tuberculosis (TB) poses a substantial burden in sub-Saharan Africa and is the leading cause of death amongst infectious diseases. Randomised controlled trials (RCTs) are regarded as the gold standard for evaluating the effectiveness of interventions. We aimed to describe published TB treatment trials conducted in Africa. Methods This is a cross-sectional study of published TB trials conducted in at least one African country. In November 2019, we searched three databases using the validated Africa search filter and Cochrane’s sensitive trial string. Published RCTs conducted in at least one African country were included for analysis. Records were screened for eligibility. Co-reviewers assisted with duplicate data extraction. Extracted data included: the country where studies were conducted, publication dates, ethics statement, trial registration number, participant’s age range. We used Cochrane’s Risk of Bias criteria to assess methodological quality. Results We identified 10,495 records; 175 trials were eligible for inclusion. RCTs were published between 1952 and 2019. The median sample size was 206 participants (interquartile range: 73–657). Most trials were conducted in South Africa (n = 83) and were drug therapy trials (n = 130). First authors were from 30 countries globally. South Africa had the most first authors (n = 55); followed by the United States of America (USA) (n = 28) and Great Britain (n = 14) with fewer other African countries contributing to the first author tally. Children under 13 years of age eligible to participate in the trials made up 17/175 trials (9.71%). International governments (n = 29) were the most prevalent funders. Ninety-four trials provided CONSORT flow diagrams. Methodological quality such as allocation concealment and blinding were poorly reported or unclear in most trials. Conclusions By mapping African TB trials, we were able to identify potential research gaps. Many of the global north’s researchers were found to be the lead authors in these African trials. Few trials tested behavioural interventions compared to drugs, and far fewer tested interventions on children compared to adults to improve TB outcomes. Lastly, funders and researchers should ensure better methodological quality reporting of trials

Emerging professional practices focusing on reducing inequity in speech-language therapy and audiology: a scoping review

Abstract Background For the professions of audiology and speech-language therapy (A/SLT), there continues be a dire need for more equitable services. Therefore there is a need to develop emerging practices which have a specific focus on equity as a driving force in shifting practices. This scoping review aimed to synthesise the characteristics of emerging practices in A/SLT clinical practice in relation to equity with an emphasis on communication professions. Methods This scoping review followed the Joanna Briggs Institute guidelines and aimed to map the emerging practices in A/SLT to identify the ways in which the professions are developing equitable practices. Papers were included if they addressed equity, focused on clinical practice and were situated within A/SLT literature. There were no time or language restrictions. The review included all sources of evidence across PubMed, Scopus, EbscoHost, The Cochrane Library and Dissertation Abstracts International, Education Resource Information Centre from their inception. The review uses PRISMA Extension for scoping reviews and PRISMA-Equity Extension reporting guidelines. Results The 20 included studies ranged from 1997–2020, spanning over 20 years. There were a variety of papers including empirical studies, commentaries, reviews and research. The results demonstrated that the professions were increasingly considering addressing equity through their practice. However, there was a prominent focus around culturally and linguistically diverse populations, with limited engagement around other intersections of marginalisation. The results also showed that while the majority of contributions to theorising equity are from the Global North with a small cluster from the Global South offering critical contributions considering social categories such as race and class. Collectively the contributions from the Global South remain a very small minority of the professional discourse which have a focus on equity. Conclusion Over the last eight years, the A/SLT professions are increasingly developing emerging practices to advance equity by engaging with marginalised communities. However, the professions have a long way to go to achieve equitable practice. The decolonial lens acknowledges the impact and influence of colonisation and coloniality in shaping inequity. Using this lens, we argue for the need to consider communication as a key aspect of health necessary to achieve health equity
