    Addressing an HIV cure in LMIC
    (2021-08-03) Ismail, Sherazaan D.; Pankrac, Joshua; Ndashimye, Emmanuel; Prodger, Jessica L.; Abrahams, Melissa-Rose; Mann, Jamie F. S.; Redd, Andrew D.; Arts, Eric J.
    HIV-1 persists in infected individuals despite years of antiretroviral therapy (ART), due to the formation of a stable and long-lived latent viral reservoir. Early ART can reduce the latent reservoir and is associated with post-treatment control in people living with HIV (PLWH). However, even in post-treatment controllers, ART cessation after a period of time inevitably results in rebound of plasma viraemia, thus lifelong treatment for viral suppression is indicated. Due to the difficulties of sustained life-long treatment in the millions of PLWH worldwide, a cure is undeniably necessary. This requires an in-depth understanding of reservoir formation and dynamics. Differences exist in treatment guidelines and accessibility to treatment as well as social stigma between low- and-middle income countries (LMICs) and high-income countries. In addition, demographic differences exist in PLWH from different geographical regions such as infecting viral subtype and host genetics, which can contribute to differences in the viral reservoir between different populations. Here, we review topics relevant to HIV-1 cure research in LMICs, with a focus on sub-Saharan Africa, the region of the world bearing the greatest burden of HIV-1. We present a summary of ART in LMICs, highlighting challenges that may be experienced in implementing a HIV-1 cure therapeutic. Furthermore, we discuss current research on the HIV-1 latent reservoir in different populations, highlighting research in LMIC and gaps in the research that may facilitate a global cure. Finally, we discuss current experimental cure strategies in the context of their potential application in LMICs.

    Building the capacity of policy-makers and planners to strengthen mental health systems in low- and middle-income countries: a systematic review
    (BioMed Central, 2016-10-21) Keynejad, Roxanne; Semrau, Maya; Toynbee, Mark; Evans-Lacko, Sara; Lund, Crick; Gureje, Oye; Ndyanabangi, Sheila; Courtin, Emilie; Abdulmalik, Jibril O; Alem, Atalay; Fekadu, Abebaw; Thornicroft, Graham; Hanlon, Charlotte
    Background: Little is known about the interventions required to build the capacity of mental health policy-makers and planners in low- and middle-income countries (LMICs). We conducted a systematic review with the primary aim of identifying and synthesizing the evidence base for building the capacity of policy-makers and planners to strengthen mental health systems in LMICs. Methods: We searched MEDLINE, Embase, PsycINFO, Web of Knowledge, Web of Science, Scopus, CINAHL, LILACS, ScieELO, Google Scholar and Cochrane databases for studies reporting evidence, experience or evaluation of capacity-building of policy-makers, service planners or managers in mental health system strengthening in LMICs. Reports in English, Spanish, Portuguese, French or German were included. Additional papers were identified by hand-searching references and contacting experts and key informants. Database searches yielded 2922 abstracts and 28 additional papers were identified. Following screening, 409 full papers were reviewed, of which 14 fulfilled inclusion criteria for the review. Data were extracted from all included papers and synthesized into a narrative review. Results: Only a small number of mental health system-related capacity-building interventions for policy-makers and planners in LMICs were described. Most models of capacity-building combined brief training with longer term mentorship, dialogue and/or the establishment of networks of support. However, rigorous research and evaluation methods were largely absent, with studies being of low quality, limiting the potential to separate mental health system strengthening outcomes from the effects of associated contextual factors. Conclusions: This review demonstrates the need for partnership approaches to building the capacity of mental health policy-makers and planners in LMICs, assessed rigorously against pre-specified conceptual frameworks and hypotheses, utilising longitudinal evaluation and mixed quantitative and qualitative approaches.

    The effect of COVID-19 on maternal newborn and child health (MNCH) services in Bangladesh, Nigeria and South Africa: call for a contextualised pandemic response in LMICs
    (2021-03-15) Ahmed, Tanvir; Rahman, Ahmed E; Amole, Taiwo G; Galadanci, Hadiza; Matjila, Mushi; Soma-Pillay, Priya; Gillespie, Bronwen M; El Arifeen, Shams; Anumba, Dilly O C
    Global response to COVID-19 pandemic has inadvertently undermined the achievement of existing public health priorities and laregely overlooked local context. Recent evidence suggests that this will cause additional maternal and childhood mortality and morbidity especially in low- and middle-income countries (LMICs). Here we have explored the contextual factors influencing maternal, neonatal and children health (MNCH) care in Bangladesh, Nigeria and South Africa amidst the pandemic. Our findings suggest that between March and May 2020, there was a reduction in utilisation of basic essential MNCH services such as antenatal care, family planning and immunization due to: a) the implementation of lockdown which triggered fear of contracting the COVID-19 and deterred people from accessing basic MNCH care, and b) a shift of focus towards pandemic, causing the detriment to other health services, and c) resource constraints. Taken together these issues have resulted in compromised provision of basic general healthcare. Given the likelihood of recurrent waves of the pandemic globally, COVID-19 mitigation plans therefore should be integrated with standard care provision to enhance system resilience to cope with all health needs. This commentary suggests a four-point contextualised mitigation plan to safeguard MNCH care during the pandemic using the observed countries as exemplars for LMIC health system adaptations to maintain the trajectory of progress regarding sustainable development goals (SDGs).

    Evaluating the role of levels of exposure to a task shared depression counselling intervention led by behavioural health counsellors: outcome and process evaluation
    (2019-06-10) Selohilwe, One; Bhana, Arvin; Garman, Emily C; Petersen, Inge
    Background In the context of a large treatment gap for common mental disorders (CMDs) and shortage of mental health specialists in low- and middle-income countries, there is increasing evidence of the effectiveness of task sharing of counselling interventions to increase access to mental health care for CMDs at primary health care level. This study evaluated the relationship between levels of exposure to a task-shared counselling intervention and psychosocial outcomes (depression, functional disability, internalised stigma and social support) in chronic care service users with comorbid depression in South Africa guided by the Medical Research Council process evaluation framework. Implementation and participant-level factors that promote greater exposure were also investigated. Method The study design was a cohort study comprising of 173 participants referred by primary health care nurses for the task-shared counselling intervention. The study site comprised four primary health care facilities in a sub-district of the Dr. Kenneth Kaunda district in the North West Province of South Africa. The participants were assessed for psychosocial outcomes at three time points: baseline, 3 months and at 12 months. The number of counselling sessions each participant was exposed to was collected for each participant. Linear regression models were used to test the influence of counselling exposure on each of the psychosocial variables between baseline and endline. In-depth qualitative interviews were conducted on 29 randomly selected participants, stratified according to exposure to counselling sessions, and analysed using framework analysis. Findings Findings from the cohort study indicated a significant reduction in depression severity at 12 months. Internalised stigma and functional disability improved from baseline to endline. Participants receiving 5–8 sessions have the greatest reduction in PHQ9 scores from baseline to endline (β = − 2.46, 95% CI − 5.06 to 0.15) compared to those with 0 sessions (β = − 0.51, 95% CI − 3.62 to 2.60, p = 0.064). The WHODAS scores decreased significantly more from baseline to endline among those who received 5–8 sessions (β = − 10.73, 95% CI − 19.86 to 1.59) compared to those with 0 sessions (β = 2.25, 95% CI − 8.65 to 13.14, p = 0.021). No significant differences as a function of levels of counselling exposure from baseline to endline was observed for OSS-3 scores. An improvement in ISMI scores from 1–4 sessions to 5–8 sessions was found (β = − 4.05, 95% CI − 7.30 to − 0.80, p = 0.015). The qualitative process evaluation indicated that the service was acceptable and accessible; but that session attendance was hindered by women’s’ caregiving burden, poor counsellor attributes and poor referral processes. Conclusion Exposure to a greater number of sessions (5–8 sessions) was found to optimize functional ability, reduce stigma, and potentially reduce depression symptoms. In order to enhance session attendance, lay counsellor delivered psychosocial interventions need to pay attention to (i) counsellor selection criteria, particularly person-centred care qualities; and (ii) strengthening referral processes in contexts where mental health literacy is low.

    The burden of pertussis in low- and middle-income countries since the inception of the Expanded Programme on Immunization (EPI) in 1974: a systematic review protocol
    (2015-05-01) Muloiwa, Rudzani; Kagina, Benjamin M; Engel, Mark E; Hussey, Gregory D
    Abstract Background Vaccine against pertussis has been in use for several decades. Despite the widespread use of pertussis vaccine, evidence shows resurgence of pertussis in high-income countries. Pertussis surveillance data is largely missing from low- and middle-income countries (LMICs). Without data on trends of pertussis, it is difficult to review and amend pertussis control policies in any country. We propose conducting a systematic review to evaluate the burden and trends of pertussis in LMICs since 1974. Methods/design Common and medical subject heading (MeSH) terms for pertussis and LMICs will be used to search electronic databases for the relevant literature published between 1974 and December 2014. Only studies from LMICs that fulfils World Health Organisation (WHO) or CDC pertussis case definitions will be included. The studies must have a clear numerator and denominator in a well-defined population. Risk of bias will be evaluated by assessing all qualifying full-text articles for quality and eligibility using a modified quality score assessment tool. Standardised data extraction will be carried out after which descriptions of trends in the prevalence, incidence, as well as mortality rate and case fatality rate, will be done. Where sufficient data is available, the results will be stratified by age group, geography, location, vaccination and HIV status. Discussion The systematic review proposed by this protocol seeks to address the knowledge gap in the epidemiology of pertussis in LMICs for the first time. It is anticipated that the background epidemiological trends of pertussis in LMICs that our study will provide could be used in the planning for the control of pertussis.

    Towards naturalistic developmental behavioural interventions for autism in Africa: nature and context of caregiver-child interactions in low-resource South African environments
    (2022) Ndlovu, Minkateko; de Vries, Petrus J; Franz, Lauren; Viljoen, Marisa
    Naturalistic developmental behavioural interventions (NDBI) are a group of evidence-based early interventions for autism spectrum disorders (ASD). Caregivers can be trained to deliver NDBI strategies during interactions with their young child with ASD. However, NDBI research predominantly comes from high-income countries, and the evidence base for NDBI in low/middle-income countries (LMICs) and across cultures is lacking. To understand the ‘fit' of an NDBI approach in LMICs, it is crucial to understand and be able to measure the nature of interactions between caregivers and their children with ASD and the context wherein caregiver-child interactions occur. This study sought a) to evaluate the utility of a specific measure of caregiver-child dyadic interactions and b) to examine daily routines in which caregiver-child interactions occurred in low-resource South African contexts. Methodology Children with ASD (between 18-72 months old) and their ≥18-year-old caregivers were recruited under a larger project. Interactions of 21 caregiver-child dyads were video-recorded using a standardised parent-child interaction (PCI) protocol with two 6-minute-long free-play sessions (Part I: child explored the room and available toys while the caregiver remained seated; Part II: caregiver interacted with their child as they would at home). Two research-reliable raters rated the videos using 16 items from the Joint Engagement Rating Inventory (JERI), a 7-point Likert scale behavioural coding system. Reliability and descriptive analyses were conducted. Structured interviews were conducted with ten caregivers using the Parent Survey of Home and Family Experiences (PSHFE) to explore the context of daily routines. Descriptive analyses were performed. Results For caregiver-child interactions, observer agreement for 12 of 16 items was reasonable, with weighted kappas (within 1 scale point) of 0.66-1, an estimated accuracy of 88-99%, and percentage agreements of 75-100% for all items. Ratings for items across Parts I and II of the JERI showed variability without any ceiling effects. Six items showed floor effects. Most caregiver item ratings were at the mid-point of the 7-point Likert scale. In Part II, children used more expressive language and paid more attention to their caregivers. On the PSHFE, most children participated daily in various child routines, play and early literacy activities with mothers as main partners. Most children never participated in spiritual and community activities, typically due to the child's age, safety and other reasons not specified in interview response categories. Conclusion Reliability, floor/ceiling, behavioural and Part I vs Part II profiles suggested that the JERI, used for the first time in a South African context, has potential utility both to describe caregiver-child interactions and be used as an intervention outcome measure in LMICs. The PSHFE results provided contextual data of common daily activities into which NDBI strategies could be embedded to support child generalisation of skills in South Africa.
