Integrating 'undetectable equals untransmittable' into HIV counselling in South Africa: the development of locally acceptable communication tools using intervention mapping.

BACKGROUND: The global campaign for "Undetectable equals Untransmittable" (U = U) seeks to spread awareness of HIV treatment as prevention, aiming to enhance psychological well-being and diminish stigma. Despite its potential benefits, U = U faces challenges in Sub-Saharan Africa, with low awareness and hesitancy to endorse it. We sought to develop a U = U communications intervention to support HIV counselling in primary healthcare settings in South Africa. METHODS: We used Intervention Mapping (IM), a theory-based framework to develop the "Undetectable and You" intervention for the South African context. The six steps of the IM protocol were systematically applied to develop the intervention including a needs assessment consisting of a systematic review and qualitative research including focus group discussions (FGD) and key informant (KI) interviews. Program objectives and target population were determined before designing the intervention components and implementation plan. RESULTS: The needs assessment indicated low global U = U awareness, especially in Africa, and scepticism about its effectiveness. Lay counsellors and clinic managers stressed the need for a simple and standardized presentation of U = U addressing both patients' needs for encouragement and modelling of U = U success but also clear guidance toward ART adherence behaviour. Findings from each step of the process informed successive steps. Our final intervention consisted of personal testimonials of PLHIV role models and their partners, organized as an App to deliver U = U information to patients in primary healthcare settings. CONCLUSIONS: We outline an intervention development strategy, currently in evaluation stage, utilizing IM with formative research and input from key U = U stakeholders and people living with HIV (PLHIV).

Why we need to re-define long-term success for people living with HIV.

Over the past few decades, the life expectancy of people living with HIV has markedly improved due to the advances in HIV diagnosis, linkage to care, and treatment. However, with these advances, a new set of challenges has emerged that must be addressed to ensure the long-term well-being of people living with HIV. In this article, as part of a wider journal supplement, we explore the unmet needs and challenges across the HIV continuum of care and re-define what long-term success looks like to support the healthy ageing of all people affected by HIV.

Long-term success for people living with HIV: A framework to guide practice.

OBJECTIVES: In recent decades, the needs of people living with HIV have evolved as life expectancy has greatly improved. Now, a new definition of long-term success (LTS) is necessary to help address the multifaceted needs of all people living with HIV. METHODS: We conducted a two-phase research programme to delineate the range of experiences of people living with HIV. The insights garnered from these research phases were explored in a series of expert-led workshops, which led to the development and refinement of the LTS framework. RESULTS: The insights generated from the research phases identified a series of themes that form a part of LTS. These themes were subsequently incorporated into the LTS framework, which includes five outcome pillars: sustained undetectable viral load, minimal impact of treatment and clinical monitoring, optimized health-related quality of life, lifelong integration of healthcare, and freedom from stigma and discrimination. A series of supporting statements were also developed by the expert panel to help in the achievement of each of the LTS pillars. CONCLUSIONS: The LTS framework offers a comprehensive and person-centric approach that, if achieved, could help improve the long-term well-being of people living with HIV and support the LTS vision of 'every person living with HIV being able to live their best life'.

Changing Knowledge and Attitudes Towards HIV Treatment-as-Prevention and "Undetectable = Untransmittable": A Systematic Review.

People on HIV treatment with undetectable virus cannot transmit HIV sexually (Undetectable = Untransmittable, U = U). However, the science of treatment-as-prevention (TasP) may not be widely understood by people with and without HIV who could benefit from this information. We systematically reviewed the global literature on knowledge and attitudes related to TasP and interventions providing TasP or U = U information. We included studies of providers, patients, and communities from all regions of the world, published 2008-2020. We screened 885 papers and abstracts and identified 72 for inclusion. Studies in high-income settings reported high awareness of TasP but gaps in knowledge about the likelihood of transmission with undetectable HIV. Greater knowledge was associated with more positive attitudes towards TasP. Extant literature shows low awareness of TasP in Africa where 2 in 3 people with HIV live. The emerging evidence on interventions delivering information on TasP suggests beneficial impacts on knowledge, stigma, HIV testing, and viral suppression.Review was pre-registered at PROSPERO: CRD42020153725.

RESUMEN: Las personas en tratamiento contra el VIH con virus indetectable no pueden transmitir el VIH sexualmente (indetectable = intransmisible, U = U por sus siglas en inglés). Pero, la ciencia del tratamiento como prevención (TasP, por sus siglas en inglés) puede que no sea ampliamente comprendida por personas con y sin VIH que podrían beneficiarse. Revisamos sistemáticamente la literatura mundial sobre conocimientos y actitudes relacionados con TasP e intervenciones que proporcionan información TasP o U = U, 2008­2020. Incluimos estudios de proveedores, pacientes y comunidades de todas las regiones del mundo. Se examinaron 885 artículos y resúmenes y se identificaron 72 para su inclusión. Los estudios en entornos de ingresos altos informaron un alto conocimiento de TasP pero existen lagunas en el conocimiento sobre la probabilidad de transmisión del VIH indetectable. Un mayor conocimiento se asoció con actitudes más positivas hacia TasP. La literatura existente muestra un escaso conocimiento de TasP en África, donde viven 2 de cada 3 personas con VIH. La evidencia emergente sobre intervenciones que brindan información sobre TasP sugiere impactos positivos en el conocimiento, el estigma, las pruebas del VIH y la supresión viral.

Call to action: how can the US Ending the HIV Epidemic initiative succeed?

With more than 1·2 million people living with HIV in the USA, a complex epidemic across the large and diverse country, and a fragmented health-care system marked by widening health disparities, the US HIV epidemic requires sustained scientific and public health attention. The epidemic has been stubbornly persistent; high incidence densities have been sustained over decades and the epidemic is increasingly concentrated among racial, ethnic, and sexual and gender minority communities. This fact remains true despite extraordinary scientific advances in prevention, treatment, and care-advances that have been led, to a substantial degree, by US-supported science and researchers. In this watershed year of 2021 and in the face of the COVID-19 pandemic, it is clear that the USA will not meet the stated goals of the National HIV/AIDS Strategy, particularly those goals relating to reductions in new infections, decreases in morbidity, and reductions in HIV stigma. The six papers in the Lancet Series on HIV in the USA have each examined the underlying causes of these challenges and laid out paths forward for an invigorated, sustained, and more equitable response to the US HIV epidemic than has been seen to date. The sciences of HIV surveillance, prevention, treatment, and implementation all suggest that the visionary goals of the Ending the HIV Epidemic initiative in the USA might be achievable. However, fundamental barriers and challenges need to be addressed and the research effort sustained if we are to succeed.

Undetectable equals untransmittable (U = U): awareness and associations with health outcomes among people living with HIV in 25 countries.

OBJECTIVES: 'Undetectable equals Untransmittable' (U=U) is an empowering message that may enable people living with HIV (PLHIV) to reach and maintain undetectability. We estimated the percentage of PLHIV who ever discussed U=U with their main HIV care provider, and measured associations with health-related outcomes. Secondarily, we evaluated whether the impact of the U=U message varied between those who heard it from their healthcare provider (HCP) vs from elsewhere. METHODS: Data were from the 25-country 2019 Positive Perspectives Survey of PLHIV on treatment (n=2389). PLHIV were classified as having discussed U=U with their HCP if they indicated that their HCP had ever told them about U=U. Those who had not discussed U=U with their HCP but were nonetheless aware that 'My HIV medication prevents me from passing on HIV to others' were classified as being made aware of U=U from non-HCP sources. Multivariable logistic regression was used to measure associations between exposure to U=U messages and health outcomes. RESULTS: Overall, 66.5% reported ever discussing U=U with their HCP, from 38.0% (South Korea) to 87.3% (Switzerland). Prevalence was lowest among heterosexual men (57.6%) and PLHIV in Asia (51.3%). Compared with those unaware of U=U, those reporting U=U discussions with their HCP had lower odds of suboptimal adherence (AOR=0.59, 95% CI 0.44 to 0.78) and higher odds of self-reported viral suppression (AOR=2.34, 95% CI 1.72 to 3.20), optimal sexual health (AOR=1.48, 95% CI 1.14 to 1.92) and reporting they 'always shared' their HIV status (AOR=2.99, 95% CI 1.42 to 6.28). While exposure to U=U information from non-HCP sources was beneficial too, the observed associations were attenuated relative to those seen with reported discussions with HCPs. CONCLUSION: HCP discussion of U=U with PLHIV was associated with favourable health outcomes. However, missed opportunities exist since a third of PLHIV reported not having any U=U discussion with their HCP. U=U discussions with PLHIV should be considered as a standard of care in clinical guidelines.

Prevalence, determinants, and impact of suboptimal adherence to HIV medication in 25 countries.

Modern antiretroviral therapy (ART) has improved the lives of people living with HIV (PLHIV) but currently requires daily adherence. We assessed prevalence and correlates of suboptimal adherence, and measured associations with self-reported health outcomes. Data were from web-based surveys of confirmed HIV+ adults on antiretroviral treatment within 25 countries during 2019 (n = 2389). Suboptimal adherence was a report of ≥1 reason for missing ART ≥5 times within the past month. Multivariable logistic regression examined associations between suboptimal adherence and self-reported overall health and virologic suppression. Overall, 24.1% (575/2389) reported suboptimal adherence, from 10.0% (5/50) in Austria, to 62.0% (31/50) in China. The most common reasons for missing ART ≥5 times in the overall population were feeling depressed/overwhelmed (7.4%, 176/2389), trying to forget about HIV (7.0%, 168/2389), and work (6.1%, 145/2389). Correlates of suboptimal adherence included being heterosexual, <50 years old, ≤high school, having gastrointestinal treatment side effects, and privacy concerns. Odds of suboptimal overall health were 1.41 (95%CI, 1.11-1.80), 2.10 (95%CI, 1.65-2.68), and 2.55 (95%CI, 2.00-3.25) among those who reported the maximum number of times missed ART for any reason within the past month as 1, 2-4, or ≥5 times respectively, vs not missing at all. Odds of virologic nonsuppression were 1.80 (95%CI, 1.33-2.45), and 2.24 (95%CI, 1.66-3.02) for 2-4, or ≥5 times of missed ART respectively, vs not missing at all; missing for only 1 time was not significantly associated with virologic nonsuppression. Novel ART strategies designed to improve adherence along with interventions to empower PLHIV and support self-medication may improve health outcomes and quality of life.

Doubly labeled water analysis using cavity ring-down spectroscopy.

The doubly labeled water method provides an objective and accurate measure of total energy expenditure in free-living subjects and is considered the gold-standard method for this measurement. Its use, however, is limited by the need to employ isotope ratio mass spectrometry (IRMS) to obtain the high-precision isotopic abundance analyses needed to optimize the dose of expensive (18) O-labeled water. Recently, cavity-ring down spectroscopy (CRDS) instruments have become commercially available and may serve as a less expensive alternative to IRMS. We compared the precision and accuracy of CRDS with those of IRMS for the measurement of total energy expenditure from urine specimens in 14 human subjects. The relative accuracy and precision (SD) for total body water was 0.5 ± 1% and for total energy expenditure was 0.5 ± 6%. The CRDS instrument displayed a memory between successive specimens of 5% for (18) O and 9% for (2) H. The memory necessitated carefully ordering of specimens to reduce isotopic disparity, performance of several injections of each specimen to condition the analyzer, and use of a mathematical memory correction on subsequent injections. These limited the specimen throughput to about one urine specimen per hour. CRDS provided accuracy and precision for isotope abundance measurements of urine that were comparable with those of IRMS. The memory problems were easily recognized by our experienced laboratory staff, but future efforts should be aimed at reducing the memory of the CRDS so that it would be less likely to result in poor reproducibility in laboratories using doubly labeled water for the first time.

Sternal osteomyelitis after minor trauma.

Sternal osteomyelitis secondary to minor trauma occurs rarely. Only a handful of cases have been reported. A 24-year-old male patient who had history of intravenous drug abuse and recent minor sternal trauma presented with signs and symptoms of sternal infection. Imaging studies suggested osteomyelitis and the patient underwent sternal resection, with a successful outcome. Sternal osteomyelitis should be suspected in immunocompromised patients, including intravenous drug abusers presenting with sternal inflammatory symptoms. Increased awareness, rapid diagnosis, and appropriate empiric antibiotic and radical surgical treatments can successfully manage life-threatening osteomyelitis of the sternum.

A comprehensive primer of surgical informed consent.

Informed consent plays a major role in forming a therapeutic alliance with the patient. The informed consent process has evolved from simple consent, in which the surgeon needed only to obtain the patient's permission for a procedure, into informed consent, in which the surgeon provides the patient with information about clinically salient features of a procedure, the patient understands this information adequately, and the patient voluntarily authorizes the surgeon to perform the procedure. Special circumstances of informed consent include conflicting professional opinions, consent with multiple physicians, patients who are undecided or refuse surgery, patients with diminished decision-making capacity, surrogate decision making, pediatric assent, and consent for the involvement of trainees.

Multiperforated atrial septal aneurysm and a single coronary artery.

Multiperforated atrial septal aneurysm (ASA) with left-to-right shunt and elevated pulmonary arterial pressure is rare. We present an adult patient with this unusual anomaly combined with a single coronary ostium emerging from the right sinus of Valsalva. The ASA was excised and the defect repaired successfully.
