Acute kidney injury (AKI) is a complex, devastating condition characterised by a sudden reduction in renal function, leading to increased mortality and healthcare costs globally. Outcomes of AKI are worsened by factors such as limited access to healthcare, delayed hospital presentation and underlying comorbidities, which severely affect patients in sub-Saharan Africa. The renal resistive index (RRI) has come into view as an encouraging non-invasive imaging approach for the early prediction of AKI. However, the use of the RRI for AKI prediction in sub-Saharan Africa is poorly documented. This research aims to map and describe the evidence for using the RRI for the early detection of AKI in sub-Saharan Africa.
The Joanna Briggs Institute methodology for scoping reviews will be used for this study. It will include a comprehensive search of electronic databases, grey literature (including academic proceedings), as well as an extensive literature review of relevant journals. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews will also be used as a guide. Discrepancies will be handled by consensus or by consulting a third reviewer. This evidence synthesis will explore the usefulness and accuracy of the RRI for early prediction of AKI in sub-Saharan Africa, where the patients are generally younger and have different AKI risk predictors and cardiovascular profiles compared with patients in high-income countries. Evidence of implementation and associated challenges will also be explored. These challenges may include limited access to specialised ultrasound equipment and a lack of trained healthcare providers proficient in RRI measurement and interpretation. The findings will inform future studies and be useful for healthcare providers, policymakers and patient advocates seeking sustainable strategies for preventing AKI.
Ethical approval is not required for this scoping review. The findings of this review will be published in a peer-reviewed journal and presented to decision-makers, health system administrators and healthcare providers at national and international academic conferences.
Cellulitis is a common bacterial skin infection causing significant pain, swelling and impact on daily activities, frequently leading to emergency department presentations and hospital admissions. While antibiotics are the mainstay of treatment, they do not directly address inflammation, often resulting in persisting or worsening symptoms in the initial days. Corticosteroids, with their potent anti-inflammatory effects, have shown benefit in other acute infections but are not currently standard care for patients with cellulitis. This trial aims to determine if adjunctive oral dexamethasone can reduce pain and improve outcomes in adults with cellulitis presenting to UK urgent secondary care settings.
This is a pragmatic, multicentre, double-blind, placebo-controlled, randomised, parallel group, phase 3 superiority trial, with an internal pilot and parallel health economic evaluation. Adult patients (≥16 years) with a clinical diagnosis of cellulitis (at any body site except the orbit) presenting to urgent secondary care will be screened for eligibility. 450 participants will be randomised (1:1) to receive either two 8 mg doses of oral dexamethasone or matched placebo, administered approximately 24 hours apart, in addition to standard antibiotic therapy. The primary outcome is total pain experienced over the first 3 days postrandomisation, calculated using the standardised area under the curve from pain scores (Numerical Rating Scale 0–10) across up to seven timepoints. Secondary outcomes include health-related quality of life (EuroQol 5 Dimension 5 Level), patient global impression of improvement, analgesia and antibiotic usage, hospital (re)admissions, complications, unscheduled healthcare use, cellulitis recurrence and cost-effectiveness at 90 days. The primary estimand will apply a treatment policy approach to intercurrent events.
The trial has received ethical approval from South Central—Oxford B Research Ethics Committee (reference: 24/SC/0289) and will be conducted in compliance with Good Clinical Practice and applicable regulations. Informed consent will be obtained from all participants. A model consent form can be seen in . Findings will be disseminated through peer-reviewed publications and conference presentations, and to patient groups and relevant clinical guideline committees.
Worldwide, maternal mortality is mostly caused by avoidable or treatable health complications, despite the progress made in maternal health. High-quality care focuses on a standardised and patient-centred approach. In this light, care bundles, which are sets of evidence-based practices, were introduced to improve the quality of care and maternal outcomes. The existing reviews on care bundles focus on specific conditions, and there is, to our knowledge, no comprehensive systematic review on the effectiveness and evidence-based character of care bundles on multiple maternal outcomes. This systematic review aims to describe maternal care bundles on labour and birth, to assess their effectiveness on maternal outcomes and to evaluate the evidence-based character of their interventions.
This systematic review will include randomised controlled trials, quasi-randomised studies, cohort studies, case-control studies, controlled before-and-after studies and interrupted-time-series studies, starting from 2001, focused on labour and childbirth stages, addressing care bundles that include multiple conditions. The search strategy will include six electronic databases (PubMed, Cochrane Library, CINAHL, Embase, Scopus and Web of Science) used to retrieve relevant titles and abstracts based on a database-specific search strategy. Titles and abstracts will be independently screened by two reviewers, followed by a full-text eligibility assessment. Reviewers will also extract data based on this review’s objectives and outcomes. Analysis will be performed in three phases: descriptive analysis, evaluation of the evidence-based character of interventions and quantitative synthesis analysis.
Ethics approval is not needed. Dissemination will be performed through publication in peer-reviewed journals, conference presentations and informing policies and stakeholders by offering a structured overview of maternal care bundles on labour and childbirth.

Photobiomodulation therapy (PBMT), particularly when combined with a static magnetic field (PBMT-sMF), is a promising non-pharmacological approach for managing musculoskeletal disorders. However, high-quality evidence for its efficacy in lateral epicondylitis remains limited.
The study aims to investigate the effectiveness of PBMT-sMF vs placebo in reducing pain, improving function and modulating inflammatory markers in individuals with lateral epicondylitis.
Multicentre, randomised, triple-blinded, placebo-controlled trial.
Three outpatient physiotherapy clinics in Brazil.
50 adults (18–50 years) with unilateral lateral epicondylitis and baseline pain ≥50 on the visual analogue scale (VAS).
Participants received either active PBMT-sMF (n=25) or placebo (n=25), 2 times per week for 3 weeks. PBMT-sMF involved multi-wavelength irradiation at 4 epicondyle sites (60 s; 27.1 J/site). The placebo group underwent the same procedure without active irradiation.
The primary outcome was degree of pain rating (VAS). Secondary outcomes included forearm disability (Patient-Rated Tennis Elbow Evaluation, PRTEE), grip strength, serum tumour necrosis factor-alpha (TNF-α) levels and treatment satisfaction. Assessments were conducted at baseline, post-treatment (3 weeks) and at 4-week follow-up.
PBMT-sMF yielded a higher responder rate (defined as the proportion of participants achieving at least a 30% reduction in pain intensity relative to baseline) than placebo (72% vs 40%, p=0.045), with a clinically and statistically significant between-group difference. Compared with placebo, the PBMT-sMF group showed significantly greater reductions in pain intensity both at the end of treatment (51.4±19.8 vs 36.9±22.6; p=0.0223) and at follow-up (37.4±24.1 vs 20.3±21.2; p=0.0049). TNF-α levels also decreased significantly in the PBMT-sMF group compared with placebo at both time points (p
PBMT-sMF significantly reduced pain intensity and TNF-α levels, suggesting an anti-inflammatory mechanism. Although functional outcomes were not improved, PBMT-sMF may be a valuable short-term, non-invasive option for lateral epicondylitis pain management.

Cancer remains a major public health concern worldwide. Patient navigation, developed in the 1990s to address disparities in cancer outcomes, aims to guide patients through the complex healthcare system and improve access to timely, quality care. Despite its proven benefits, little is known about the implementation or impact of patient navigation programmes in African settings.
This scoping review aims to map the current evidence on components, procedures, outcomes and impact, as well as barriers and challenges to implementation of patient navigation programmes in cancer care across Africa.
This scoping review will follow Arksey and O’Malley’s scoping review framework, as further developed by Levac et al. A systematic search will be conducted across PubMed, African Journals Online and Google Scholar to identify relevant studies published from database inception to the date of the final search, using a combination of relevant keywords and MeSH terms. Eligible studies must be reported in English, have been carried out in Africa, involved patients diagnosed with cancer or navigating the cancer care continuum, and report on the description, implementation or evaluation of patient navigation programmes. Screening will be managed with Rayyan and carried out through a two-stage process: screening by titles and abstracts, then by full-text screening based on the prespecified inclusion and exclusion criteria. Data will be extracted into a structured Excel spreadsheet and synthesised using qualitative content analysis to identify programme characteristics, outcomes, barriers and implementation challenges.
This scoping review does not require ethical approval. Our findings will be published in a peer-reviewed, open-access journal on completion.
The mental health of people living with HIV (PLWH) is a growing concern globally, particularly in sub-Saharan Africa (SSA), where there is limited access to mental healthcare, with evidence showing high levels of depression, anxiety and neurocognitive disorders among this population. While Mental Health Disorders (MHDs) can impede HIV care and promote adverse health outcomes, there is limited literature on MHDs among PLWH. This scoping review will explore the existing literature on the burden and factors associated with MHDs among adults living with HIV in SSA.
Arksey and O’Malley’s methodological framework will guide the search of this scoping review. Relevant original research articles published in English from 1 January 2000 to 31 May 2025 on MHDs among PLWH in SSA will be identified through searches in the African Index Medicus, African Journal Online, PubMed and Embase databases. Four independent reviewers, working in pairs (one reviewer and one verifier), will screen the titles, abstracts and later the full texts, adopting the population, concept and context framework. Other coauthors will serve as tiebreakers whenever there is disagreement on the eligibility. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews flowchart will be presented. We will perform a narrative synthesis to report our findings.
This scoping review protocol does not require ethical approval, as it relies solely on publicly available existing data and does not involve human participants. We will disseminate the findings from this review through peer-reviewed publications and presentations at local and international conferences.
The protocol was registered in the Open Science Framework (https://osf.io/8ymqu).
Globally, drug shortages affect low-, middle- and high-income countries to different degrees. The challenges associated with drug shortages in health systems, particularly in public health facilities, and the consequent multiple adverse effects on patients and the health systems have led countries to continue to explore and implement different strategies to combat this challenge. Various factors implicated in drug shortages range from manufacturing concerns, demand issues, supply chain disruptions and regulatory issues. The effects of drug shortages in health systems range from poor patient compliance and therapeutic failure to antimicrobial resistance, low morale among healthcare workers and public distrust in government services. Furthermore, the effects of drug shortages in public health facilities include unavailability of drugs to patients, hospitalisation and readmissions, and associated costs that could be avoided, high out-of-pocket expenditures suffered by patients as patients resort to buying drugs from private pharmacies where the prices are usually exorbitant and prohibitive, putting patients at risk of treatment default due to lack of affordability. Successful mitigation strategies deployed to prevent and manage drug shortages in sub-Saharan Africa (SSA) remain unshared despite the potential of these strategies to serve as valuable lessons if the evidence is scientifically synthesised and reported. The scoping review will synthesise evidence to provide policy guidance for better planning of health services and resources, resulting in improved quality of life for citizens, underscoring the importance of functional and responsive health systems.
Using the Joanna Briggs Institute (JBI) scoping review methodology, a five-stage review is outlined: (1) determining the research question, (2) search strategy, (3) inclusion criteria, (4) data extraction and (5) analysis and presentation of the results. The literature search will use PubMed, SCOPUS and the Elsevier Science Direct search interfaces, reflecting empirical and grey literature. We will focus on literature published between 2000 and 2025. The study start and end dates are 1 September–30 November 2025. A two-stage screening process will be used to determine the eligibility of articles. All articles will be individually assessed for eligibility by two reviewers, while a third reviewer will resolve any disagreements. The data from eligible articles will be extracted and charted using a standardised form. Extracted data will be analysed using narrative and descriptive analyses.
Ethical approval is not required for this scoping review as it will use only previously published data. It does not require human participation. The results of this search will be disseminated through academic presentations at conferences and peer-reviewed publications.
