RESUMEN

In March 2020, the South African government imposed a lockdown to control COVID-19 transmission. Lockdown may affect people living with HIV's (PLWH) antiretroviral therapy (ART) adherence. Data from a cluster randomised control trial was collected from 152 PLWH in Cape Town sub-districts from October 2019-March 2020 when the lockdown halted collection. Subsequently, 83 PLWH were followed-up in June-July 2020. Random effects models were used to analyse: (1) changes between baseline and follow-up and (2) correlates of adherence during lockdown. At follow-up, there was an increase in the odds of being below the poverty line and the odds of experiencing violence decreased. Measures for well-being, household functioning, stigma and HIV competency improved. Violence, depression, food insecurity, and stigma were associated with poorer ART adherence; higher well-being scores were associated with better adherence. During lockdown, governments need to ensure financial support, access to (mental) health services, and services for those experiencing violence.Clinical Trial Number: Pan African Clinical Trial Registry, PACTR201906476052236.

RESUMEN: En marzo de 2020, el gobierno sudafricano impuso un confinamiento generalizado para controlar la transmisión del COVID-19. Estas medidas pueden afectar la adherencia a la terapia antirretroviral de las personas con VIH. A partir de un ensayo aleatorio grupal se recopilan datos de 152 personas con VIH en los sub-distritos de Ciudad del Cabo entre octubre de 2019 y marzo de 2020 cuando el confinamiento detuvo la recopilación. Posteriormente, se realizó un seguimiento de 83 pacientes entre junio y julio de 2020. Se utilizaron modelos de efectos aleatorios para analizar: 1) los cambios en las variables entre la línea de base y de seguimiento; 2) covariables de adhesión al tratamiento. En el seguimiento se observa que aumentaron las probabilidades de estar por debajo del umbral de pobreza y disminuyeron las probabilidades de sufrir violencia. Las medidas de bienestar, funcionamiento del hogar, estigma e idoneidad en materia de VIH mejoraron entre la línea base y el seguimiento. Por otro lado, la violencia, la depresión, la inseguridad alimentaria y el estigma se asocian a una menor adherencia al tratamiento antirretroviral, mientras la mejora del bienestar se asocia a una mayor adherencia al tratamiento. De tal manera, se observa que durante situaciones de emergencia que requieran de confinamientos es recomendable que los gobiernos garanticen apoyo financiero, atención a la salud física y mental de manera continua, así como servicios especializados hacia quienes sufren violencia.

RESUMEN

BACKGROUND: HIV remains a major public health challenge in many low- and middle-income countries (LMICs). The initiation of a greater number of people living with HIV (PLHIV) onto antiretroviral therapy (ART) following the World Health Organization's 'universal test and treat' recommendation has the potential to overstretch already challenged health systems in LMICs. While various mainstream and community-based care models have been implemented to improve the treatment outcomes of PLHIV, little effort has been made to harness the potential of the families or households of PLHIV to enhance their treatment outcomes. To this end, we sought to explore the characteristics and effectiveness of household-focused interventions in LMICs on the management of HIV as measured by levels of adherence, viral suppression and different dimensions of HIV competence. Additionally, we sought to explore the mechanisms of change to explain how the interventions achieved the expected outcomes. METHODS: We systematically reviewed the literature published from 2003 to 2018, obtained from six electronic databases. We thematically analysed the 11 selected articles guided by the population, intervention, comparison and outcome (PICO) framework. Following the generative causality logic, whereby mechanisms are postulated to mediate an intervention and the outcomes, we applied a mechanism-based inferential reasoning, retroduction, to identify the mechanisms underlying the interventions to understand how these interventions are expected to work. RESULTS: The identified HIV-related interventions with a household focus were multi-component and multi-dimensional, incorporating aspects of information sharing on HIV; improving communication; stimulating social support and promoting mental health. Most of the interventions sought to empower and stimulate self-efficacy while strengthening the perceived social support of the PLHIV. Studies reported a significant positive impact on improving various aspects of HIV competent household - positive effects on HIV knowledge, communication between household members, and improved mental health outcomes of youths living in HIV-affected households. CONCLUSION: By aiming to strengthen the perceived social support and self-efficacy of PLHIV, household-focused HIV interventions can address various aspects of household HIV competency. Nevertheless, the role of the household as an enabling resource to improve the outcomes of PLHIV remains largely untapped by public HIV programmes; more research on improving household HIV competency is therefore required.

RESUMEN

Magnetic resonance (MR) arthrography has, to a great extent, replaced conventional and CT arthrography as the standard of care imaging tool for indications including medial elbow pain in the throwing athlete, chondral and osteochondral lesions in the elbow, and intra-articular bodies. There are still rare specific incidences where CT arthrography is indicated. This article reviews elbow arthrography, with a greater emphasis placed on MR arthrography, including indications, technique, potential complications, contraindications, equipment, and MR arthrographic pathologies.

RESUMEN

INTRODUCTION: The scale-up of access to antiretroviral therapy has transformed HIV from an acute, terminal disease to a manageable chronic illness. Yet, sustaining high levels of antiretroviral therapy adherence remain a challenge, especially in the sub-Saharan Africa region which is disproportionately affected by HIV. This protocol proposes a scoping review to explore literature reporting on the antiretroviral therapy adherence levels among people who experience substance abuse and violence (SAVA) syndemics, as well as mood disorders such as anxiety and depression among people living with HIV in sub-Saharan Africa. METHODS AND ANALYSIS: This proposed scoping review will follow Arksey and O'Malley's methodological framework for conducting scoping reviews as refined by Levac et al. The review will follow the Joanna Briggs Institute's manual for conducting scoping reviews. Literature searches will be conducted using six databases: Academic search complete; APA PsycArticles; CINAHL; MEDLINE; SocINDEX and Web of science. Title screening will see the "Participant, Concept, Context" framework applied to identify relevant literature and will not include the appraisal of search results. Data charting will follow an adapted version of Trico and colleagues' PRISMA-ScR and results will be mapped descriptively and in tabular format. Furthermore, results will be discussed within the syndemics model of health, and summarised as a biosocial conceptual model. ETHICS AND DISSEMINATION: The study will make use of secondary data that are readily available to the public and will not require ethical approval. We intend to publish our results in a peer-reviewed journal and disseminate our findings at relevant conferences and seminars.

RESUMEN

BACKGROUND: With 7.7 million South Africans currently infected with human immunodeficiency virus (HIV) and 4.8 million currently receiving antiretroviral treatment (ART), the epidemic represents a considerable burden for the country's resource-limited health system. In response to the health and human resource shortages, task shifting to community health workers (CHWs) and empowering people living with HIV (PLWH) are integral parts of a sustainable ART strategy. Despite the success of the ART programme, South Africa still faces both prevention and treatment challenges. To tackle these challenges, future endeavours need to focus on the role played by the households of PLWH in mediating between the community and PLWH themselves. Building health-enabling "HIV competent" households with the capacity to actively stimulate lifestyles that foster health, offers a potential strategy to tackle South Africa's HIV-related challenges. The aim of the "Sinako: Households and HIV" study is to investigate to what extent and how an intervention can increase HIV competence in PLWH and their households, and subsequently optimise the impact of CHW support on individual ART outcomes. METHODS: The "Sinako" study is a cluster-randomised controlled trial with two arms. In the control arm, CHWs offer a standard package of support to PLWH during home visits, focused on the individual. The intervention arm includes both a focus on the individual and the household to enable the patient to self-manage their treatment within an HIV competent household. A longitudinal mixed methods design is adopted to analyse the data. For the quantitative data analysis, methods including latent cross-lagged modelling, multilevel modelling and logistic regression will be used. To assess the acceptability and feasibility of the intervention and to construct a comprehensive picture of the mechanisms underlying the impact on the household and the PLWH, qualitative data (in-depth interviews and focus group discussions) will be collected and analysed. DISCUSSION: Stimulating HIV competence in households could be a feasible and sustainable strategy to optimise the outcomes of CHW interventions and thus be important for HIV treatment interventions in resource-limited settings.

RESUMEN

Despite the Universal Test and Treat program and widespread antiretroviral treatment rollout, South Africa is still facing HIV prevention and treatment challenges, which are aggravated by human resource shortages in the healthcare sector. Individual- and community-level responses to these HIV-related challenges are increasingly being explored, for example, in community and home-based care. The role of the household as a crucial mediating social level has, however, largely been omitted. This paper outlines the design of an intervention to stimulate the involvement of the household in support for people living with HIV in South Africa. The 6SQuID model guided the intervention development process in four phases: (1) formative research, theory formulation, and a review of the existing literature, (2) integration of the results from the formative research into the "Positive Communication Process" (P2CP model) as a mechanism of change, (3) design of a community-health-worker-led intervention as the way to deliver the change mechanism, and (4) testing and revision of the developed intervention material-called Sinako-in a small-scale pilot study. The Sinako intervention anticipates that the future of chronic HIV care in resource-constrained settings will need to integrate the patient's household into the fight against HIV.

RESUMEN

Adherence to HIV antiretroviral therapy (ART) is a crucial factor in health outcomes for people living with HIV (PLWH). Interventions to support ART adherence are increasingly focused on the household as a source of social support. This review aims to examine the social and structural determinants of support for ART adherence within households and families in low- and middle-income countries (LMICs). The review methodology followed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Seven databases were searched for peer-reviewed literature. The terms searched thematically covered (1) ART adherence, (2) household and family and (3) support and care. Thirty-three studies conducted in 15 LMICs were selected and a mixed methods synthesis was undertaken. Social and structural determinants affected the type, quality and amount of support for PLWH of all ages, which affected PLWH's ART adherence. Gender norms affected the type of support that household members give to PLWH. Education moderated household support for ART adherence through literacy and language skills. Cultural context, religious beliefs, and social norms reinforced or undermined household support for ART adherence. Stigma affected disclosure, generated secrecy around giving medication and impeded access to support from the community. Supporting PLWH exacerbated economic hardship for household members. Health system dysfunction negatively impacted trust and communication between household members and health professionals. Intersecting social and structural determinants particularly affected the care given by household members who were older, female, with little education and low socioeconomic status. Household members were able to overcome some of these barriers when they received support themselves. Household interventions to support PLWH's ART adherence should take structural factors into account to have maximum impact.

RESUMEN

BACKGROUND CONTEXT: Substantial variation exists regarding the use of sedation before interventional spine techniques. Patient preference should play an important role in decision making regarding the need for sedation. However, little is known about patients' anxiety levels before spinal injections and their perceptions about the necessity of sedation. PURPOSE: To determine patient perception for need for sedation before epidural steroid injections and zygapophyseal joint injections. STUDY DESIGN/SETTING: Survey of consecutive spinal injection patients in an outpatient spine center. PATIENT SAMPLE: 500 consecutive lumbar, thoracic, and cervical patients receiving spinal injections. OUTCOME MEASURES: A 12-item questionnaire assessing patients' perceived anxiety before to a spinal injection. METHODS: Subjects were given the questionnaire after their spinal injection. Percentages requesting sedation for a first and potential second procedure were assessed. Additionally, anxiety level and pain rating, location of injection, age, sex, and other medication use were analyzed to determine the effect on the request for sedation. RESULTS: 17% of patients questioned requested sedation before an injection, and 28% would request sedation if they were to have a second injection. CONCLUSIONS: Routine sedation before diagnostic and therapeutic injections is not necessary as the majority of patients would not request sedation before the procedure when given the option. However, in some patients sedation is indicated, and all patients would benefit from educational material on sedation before the injection.

RESUMEN

BACKGROUND: Great variability exists in the reported frequency of transitional vertebra in the general population as well as in symptomatic lumbar spine patients. OBJECTIVE: To determine the occurrence rate of transitional vertebra in consecutive lumbar spine patients in our practice. DESIGN: A prospective, observational study METHODS: Plain films were viewed and the presence or absence of a lumbar transitional vertebra was documented. Transitional vertebrae were classified as incomplete or complete. RESULTS: Of the 300 consecutive patients, 30% had a transitional vertebra. CONCLUSION: Our percentage of patients with a transitional vertebra was higher than the percentages reported for the general population. This supports our belief that the alteration in mechanics caused by a transitional vertebra may at times contribute to pain generation. Additionally, as a transitional segment may not always be visualized on MRI, obtaining plain films prior to an injection or surgery will help prevent confusion over the appropriate level for the procedure.
