    Determinants and acceptability of HIV self-testing among vulnerable groups in sub-Saharan Africa : a scoping review protocol
    (BMJ, 2024-01-29) Anyiam, Felix Emeka; Sibiya, Maureen Nokuthula; Oladimeji, Olanrewaju
    HIV self-testing (HIVST) is where individuals collect their specimens and perform the HIV test privately. HIVST has improved testing uptake and coverage, especially among vulnerable groups of sub-Saharan Africa (SSA). Vulnerable groups include key populations such as men who have sex with men, sex workers, people who inject drugs, lesbian, gay, bisexual and transgender persons and young women. However, little is known about the determinants and acceptability of HIVST among these groups in SSA. Therefore, this scoping review aims to explore the determinants and acceptability of HIVST among vulnerable groups in SSA.

    Methods

    A scoping review will be conducted using the Arksey and O'Malley framework and further refined by Levac framework. The review will follow a six-step approach: (1) identifying the research question, (2) identifying relevant studies, (3) study selection eligibility, (4) charting the data, (5) collating, summarising and reporting the results and (6) consultation. A comprehensive search strategy will be developed, and the following electronic databases will be searched: MEDLINE, Embase, Global Health and the Cochrane Library. Grey literature will also be searched, including conference abstracts and reports. Eligibility criteria will include studies conducted in SSA, published between 2010 and 2023, focusing on vulnerable groups and exploring the determinants and acceptability of HIVST. Two independent reviewers will screen identified studies' titles, abstracts and full texts. Any disagreements will be resolved through discussion or consultation with a third reviewer. Data extraction will be conducted using a standardised form.

    Ethics and dissemination

    This review, not requiring ethical approval, aims to inform policy and intervention design to boost HIV testing adoption within vulnerable communities. We plan to disseminate our findings via a peer-reviewed journal, policy briefs, conference presentations and stakeholder engagement.

    Motion palpation used as a postmanipulation assessment tool for monitoring end-feel improvement : a randomized controlled trial of test responsiveness
    (Elsevier BV, 2009-09) Lakhani, Ekta; Nook, Brian; Haas, Mitchell; Docrat, Aadil
    A tenet of motion palpation theory is the ability to confirm postadjustive segmental end-feel improvement (EFI). Only one previous trial has evaluated the responsiveness of EFI; this was a study of the thoracic spine. The purpose of this study was to evaluate the responsiveness of postadjustive end-feel for evaluating improvement in putative segmental spinal motion restriction after spinal manipulative therapy (SMT) of the cervical spine.

    Methods

    A prospective, blinded, randomized placebo-controlled pilot trial was conducted with 20 symptomatic and 10 asymptomatic participants recruited from a chiropractic teaching clinic. The treatment group received SMT, and the control group received placebo detuned ultrasound. Responsiveness was evaluated as the etiologic fraction (% of cases with EFI attributable to SMT) and as the sensitivity and specificity of change.

    Results

    For the entire sample, the etiologic fraction was 63% (P = .002), sensitivity was 93%, and specificity was 67%. For symptomatic participants, a strong relationship appeared to exist between receiving SMT and EFI (etiologic fraction = 78%, P = .006; sensitivity = 90%; specificity = 80%). A strong relationship was not found for asymptomatic participants (etiologic fraction = 40%, P = .444; sensitivity = 100%; specificity = 40%), where EFI was recorded frequently, whether participants received SMT or detuned ultrasound.

    Conclusion

    The findings of this study showed that motion palpation of end-feel assessment appears to be a responsive postmanipulation assessment tool in the cervical spine for determining whether perceived motion restriction found before treatment improves after SMT. This observation may be limited to symptomatic participants.
