ABSTRACT

BACKGROUND AND AIM: Long Covid is often stigmatised, particularly in people who are disadvantaged within society. This may prevent them from seeking help and could lead to widening health inequalities. This coproduced study with a Community Advisory Board (CAB) of people with Long Covid aimed to understand healthcare and wider barriers and stigma experienced by people with probable Long Covid. METHODS: An active case finding approach was employed to find adults with probable, but not yet clinically diagnosed, Long Covid in two localities in London (Camden and Merton) and Derbyshire, England. Interviews explored the barriers to care and the stigma faced by participants and were analysed thematically. This study forms part of the STIMULATE-ICP Collaboration. FINDINGS: Twenty-three interviews were completed. Participants reported limited awareness of what Long Covid is and the available pathways to management. There was considerable self-doubt among participants, sometimes reinforced by interactions with healthcare professionals (HCPs). Participants questioned their deservedness in seeking healthcare support for their symptoms. Hesitancy to engage with healthcare services was motivated by fear of needing more investigation and concerns regarding judgement about the ability to carry out caregiving responsibilities. It was also motivated by the complexity of the clinical presentation and fear of all symptoms being attributed to poor mental health. Participants also reported trying to avoid overburdening the health system. These difficulties were compounded by experiences of stigma and discrimination. The emerging themes reaffirmed a framework of epistemic injustice in relation to Long Covid, where creating, interpreting and conveying knowledge has varied credibility based on the teller's identity characteristics and/or the level of their interpretive resources. CONCLUSION: We have codeveloped recommendations based on the findings. These include early signposting to services, dedicating protected time to listening to people with Long Covid, providing a holistic approach in care pathways, and working to mitigate stigma. Regardless of the diagnosis, people experiencing new symptoms must be encouraged to seek timely medical help. Clear public health messaging is needed among communities already disadvantaged by epistemic injustice to raise awareness of Long Covid, and to share stories that encourage seeking care and to illustrate the adverse effects of stigma. PATIENT OR PUBLIC CONTRIBUTION: This study was coproduced with a CAB made up of 23 members including HCPs, people with lived experience of Long Covid and other stakeholders.

ABSTRACT

People living with HIV (PLWH) experience a disproportionate burden of mental health problems compared to people living without HIV. This systematic review aims to depict the spectrum of resilience resources that may promote the mental health of PLWH at the individual, interpersonal, organisational, community and policy levels. A systematic literature search was conducted in PsycINFO, Scopus, Medline and advanced Google Scholar. The quality of included studies was assessed using the Mixed Methods Appraisal Tool (MMAT). Of the 591 studies identified, fourteen were included representing a total of 5,142 PLWH from China, Ghana, Nepal, Spain, Tanzania and the USA. Resilience resources were identified at the individual level (self-efficacy, self-esteem, acceptance, hope, optimism, religiosity/spirituality, belief in fate, mindfulness, strength and self-responsibility); interpersonal level (social support and parental monitoring); and community level (attending HIV clinic support groups and access to healthcare). All quantitative studies were cross-sectional, limiting inferences about causation or directionality. Future research should focus on resilience resources at the organisational and policy levels and incorporate longitudinal designs.

ABSTRACT

BACKGROUND: Transgender and nonbinary (TNB) people face barriers to primary care, which remains the main entry point for accessing gender-affirming healthcare in the UK. OBJECTIVES: This systematic review aims to summarise the evidence regarding TNB people's experiences of primary care to inform improvements in service and patient outcomes. METHODS: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines. A systematic literature search was conducted across articles from 2005 to April 2023 across Ovid Medline, Ovid Embase and PsychInfo using established keywords relating to gender identity, primary care and experiences. Qualitative data were thematically analysed and quantitative data were compiled using a descriptive narrative. RESULTS: Following eligibility criteria, 16 articles were included in this review. This review identified both facilitators and limitations and barriers experienced by TNB people related to primary care provider knowledge; the patient-provider relationship, and healthcare settings. Quantitative findings reported up to 54.4% of participants were uncomfortable discussing TNB issues with their physician. Overall findings suggest TNB people face discrimination on a systemic level utilising primary care services, though positive healthcare encounters at a local level were reported. Participants expressed a desire for primary care-led gender-affirming healthcare services, with involvement from local TNB communities. CONCLUSION: This review demonstrates TNB people's mixed experiences of primary care alongside their recommendations for service improvement. This is the first systematically reviewed evidence on the topic, emphasising the need for clinicians and policymakers to centre the voices of the TNB community in service design and improvement.


Many TNB participants had negative experiences in primary care, attributed to a lack of healthcare provider knowledge and medical gatekeeping.Many TNB participants desired gender-affirming healthcare services to be more primary care-led.Primary care services should consult local TNB communities in service design, evaluation and improvement.

ABSTRACT

This study aimed to elucidate the intrinsic and extrinsic resilience resources among people living with HIV (PLWH) during the Covid pandemic. Autoethnographic video diaries from 29 PLWH from Argentina, UK, Philippines, Zimbabwe, and Trinidad and Tobago were included. Data were thematically analysed and validated with community partners and a video was co-produced. PLWH displayed a readiness to adopt healthy behaviours and engage in optimistic and constructive thinking about the future. Hobbies and daily activities, supportive relationships with peers living with HIV, family and friends, opportunities to mobilise and contribute to their communities in meaningful ways, supportive healthcare providers and reliable access to antiretroviral treatment helped foster psychological resilience among PLWH. The extrinsic resilience resources also supported positive physical health outcomes among PLWH through improved medication adherence.

ABSTRACT

BACKGROUND: A proportion of people infected with SARS-CoV-2 develop post-COVID-19 condition (also known as long COVID), a predominantly multisystem condition resulting in varying degrees of functional disability limiting day-to-day activities. We aimed to describe the impact of long COVID on work. METHODS: We co-produced baseline and follow-up online surveys with people with lived experience of long COVID (including three of the co-authors). Respondents were aged 18 years and older with self-reported long COVID following confirmed or suspected COVID-19 infection who were not hospitalised in the first 2 weeks of illness. The baseline survey was administered in November, 2020, using convenience non-probability sampling through social media. Following informed consent, participants completed a follow-up survey at 1 year (November, 2021). Ethics approval was granted by the University of Southampton. FINDINGS: Of 2210 invited, 1153 (52%) participants responded to the survey (mean age of 47·7 years [SD 10·6], 965 [84%] female, 1096 [95%] White, and 892 [78%] holding a university degree). 54 participants (4·7%) reported recovery at follow-up. Median duration of illness was 19·8 months (IQR 19·3-20·1) at follow-up. An equal proportion reported being unable to work at baseline (20·4%, n=235) and follow-up (20·6%, n=237). However, a higher proportion reported being made redundant or taking early retirement at follow-up (8·9%, n=102) than at baseline (2·2%, n=25). 209 (18·1%) reported losing or resigning or leaving their job due to long COVID at follow-up compared with 170 (14·8%) participants at baseline. 307 (26·6%) participants reported not taking time off-sick due to long COVID at baseline, decreasing to 122 (10·6%) at follow-up. Of the 656 individuals reporting length of time off-sick, 354 (54%) were off-sick for more than 3 months, with 113 (17·2%) off-sick for more than 12 months. Nearly half (47%, n=538) reported a loss in income. INTERPRETATION: The convenience non-probability sampling limits generalisability. Research is needed in a representative population sample to characterise the effect on working patterns in people with long COVID, particularly in those with less flexible and more physically demanding occupations who may be less able to take time off to recover. FUNDING: None.

ABSTRACT

The transport of cations in the cardiomyocytes, crucial for the functioning of the heart, can be affected by walnut diet due to the high content of polyunsaturated fatty acids. Healthy and metabolically compromised rats (drinking 10% fructose solution) were subjected to a diet supplemented with 2.4 g of walnuts for 6 weeks to investigate the effect on proteins involved in cation transport in the heart cells. Fructose increased the level of the α1 subunit of Na+/K+-ATPase and the phosphorylation of extracellular signal-regulated kinase 1/2 in the heart of control and walnut-eating rats, while elevated L-type calcium channel α (LTCCα), sodium-calcium exchanger 1 (NCX1), and Maxi Kα level were observed only in rats that did not consume walnuts. However, walnuts significantly increased the cardiac content of LTCC, NCX1, and Maxi Kα, as well as Kir6.1 and SUR2B subunits of KATP channel, but only in fructose-naive rats. In animals that drank fructose, a significant increasing effect of walnuts was observed only in Akt kinase phosphorylation, which may be a part of the antiarrhythmic mechanism of decreasing cation currents in cardiomyocytes. The walnut diet-induced increase in LTCC and NCX1 expression in healthy rats may indicate intense cardiac calcium turnover, whereas the effect on Kir6.1 and SUR2B subunits suggests stimulation of KATP channel transport in the cardiac vasculature. The effects of walnuts on the cation-handling proteins in the heart, mostly limited to healthy animals, suggest the possible use of a walnut-supplemented diet in the prevention rather than the treatment of cardiological channelopathies.

ABSTRACT

BACKGROUND: Recent years have seen record levels of migration to Europe. Female migrants are at heightened risk of developing mental health disorders, yet they face barriers to accessing mental health services in their host countries. This systematic review aims to summarise the barriers and facilitators to accessing mental health support for female migrants in Europe. METHODS: The review follows PRISMA guidelines, and the protocol was pre-published on PROSPERO. Six electronic databases were searched: CINAHL, Global Health Database, Medline, PsycARTICLES, PsycINFO and Web of Science. Thematic analysis was undertaken on the identified studies. A feminist quality appraisal tool was applied. RESULTS: Eight qualitative, six quantitative and five mixed methods studies were identified. Barriers included a lack of information, stigma, religious and cultural practices and beliefs, and a lack of consideration of gender-specific needs within the health system. Gender-sensitive services, supportive general practitioners and religious leaders facilitated access. CONCLUSIONS: The design of mental health research, services, policies, and commissioning of support for migrants must consider female migrant needs. Mental health support services must be culturally aware and gender sensitive. REGISTRATION: The review protocol was registered on the International Prospective Register of Systematic Reviews (PROSPERO, registration number CRD42021235571.

ABSTRACT

Adolescents and men are two populations that perform poorly within the HIV cascade of care, having worse AIDS-related health outcomes, and experiencing higher levels of HIV-related stigma. This paper explores institutional health system discrimination as experienced by adolescent boys with perinatally-acquired HIV, situating them within the social and gendered contexts of the Eastern Cape Province, South Africa. Life history narratives (n = 36) and in-depth semi-structured interviews (n = 32) with adolescent boys living with HIV aged 13-22 were conducted in 2017-2018. In-depth semi-structured interviews with biomedical and traditional health practitioners (n = 14), analysis of health facility files (n = 41) and clinic observations were also conducted. Together, triangulated sources point to an incongruence between the complex needs of adoelscent boys and young men living with HIV and their experiences within the health system. Two institutional discrimination-related deterrents to retention in care were identified: (1) lack of confidentiality due to health facility layouts and practices that visibilised people living with HIV; and (2) mistreatment in the form of shouting. This article contributes to the limited literature on the experiences of young men within the HIV continuum of care, focusing on how stigma influences how young men experience and engage with the health sector.

ABSTRACT

BACKGROUND AND AIM: Long Covid is a significant public health concern with potentially negative implications for health inequalities. We know that those who are already socially disadvantaged in society are more exposed to COVID-19, experience the worst health outcomes and are more likely to suffer economically. We also know that these groups are more likely to experience stigma and have negative healthcare experiences even before the pandemic. However, little is known about disadvantaged groups' experiences of Long Covid, and preliminary evidence suggests they may be under-represented in those who access formal care. We will conduct a pilot study in a defined geographical area in London, United Kingdom to test the feasibility of a community-based approach of identifying Long Covid cases that have not been clinically diagnosed and have not been referred to Long Covid specialist services. We will explore the barriers to accessing recognition, care, and support, as well as experiences of stigma and perceived discrimination. METHODS: This protocol and study materials were co-produced with a Community Advisory Board (CAB) made up primarily of people living with Long Covid. Working with voluntary organisations, a study leaflet will be distributed in the local community to highlight Long Covid symptoms and invite those experiencing them to participate in the study if they are not formally diagnosed. Potential participants will be assessed according to the study's inclusion criteria and offered the opportunity to participate if they fit them. Awareness of Long Covid and associated symptoms, experiences of trying to access care, as well as stigma and discrimination will be explored through qualitative interviews with participants. Upon completion of the interviews, participants will be offered a referral to the local social prescribing team to receive support that is personalised to them potentially including, but not restricted to, liaising with their primary care provider and the regional Long Covid clinic.

ABSTRACT

BACKGROUND: Stigma can be experienced as perceived or actual disqualification from social and institutional acceptance on the basis of one or more physical, behavioural or other attributes deemed to be undesirable. Long Covid is a predominantly multisystem condition that occurs in people with a history of SARSCoV2 infection, often resulting in functional disability. This study aimed to develop and validate a Long Covid Stigma Scale (LCSS); and to quantify the burden of Long Covid stigma. METHODS: Data from the follow-up of a co-produced community-based Long Covid online survey using convenience non-probability sampling was used. Thirteen questions on stigma were designed to develop the LCSS capturing three domains-enacted (overt experiences of discrimination), internalised (internalising negative associations with Long Covid and accepting them as self-applicable) and anticipated (expectation of bias/poor treatment by others) stigma. Confirmatory factor analysis tested whether LCSS consisted of the three hypothesised domains. Model fit was assessed and prevalence was calculated. RESULTS: 966 UK-based participants responded (888 for stigma questions), with mean age 48 years (SD: 10.7) and 85% female. Factor loadings for enacted stigma were 0.70-0.86, internalised 0.75-0.84, anticipated 0.58-0.87, and model fit was good. The prevalence of experiencing stigma at least 'sometimes' and 'often/always' was 95% and 76% respectively. Anticipated and internalised stigma were more frequently experienced than enacted stigma. Those who reported having a clinical diagnosis of Long Covid had higher stigma prevalence than those without. CONCLUSION: This study establishes a scale to measure Long Covid stigma and highlights common experiences of stigma in people living with Long Covid.

ABSTRACT

INTRODUCTION: Individuals with Long Covid represent a new and growing patient population. In England, fewer than 90 Long Covid clinics deliver assessment and treatment informed by NICE guidelines. However, a paucity of clinical trials or longitudinal cohort studies means that the epidemiology, clinical trajectory, healthcare utilisation and effectiveness of current Long Covid care are poorly documented, and that neither evidence-based treatments nor rehabilitation strategies exist. In addition, and in part due to pre-pandemic health inequalities, access to referral and care varies, and patient experience of the Long Covid care pathways can be poor. In a mixed methods study, we therefore aim to: (1) describe the usual healthcare, outcomes and resource utilisation of individuals with Long Covid; (2) assess the extent of inequalities in access to Long Covid care, and specifically to understand Long Covid patients' experiences of stigma and discrimination. METHODS AND ANALYSIS: A mixed methods study will address our aims. Qualitative data collection from patients and health professionals will be achieved through surveys, interviews and focus group discussions, to understand their experience and document the function of clinics. A patient cohort study will provide an understanding of outcomes and costs of care. Accessible data will be further analysed to understand the nature of Long Covid, and the care received. ETHICS AND DISSEMINATION: Ethical approval was obtained from South Central-Berkshire Research Ethics Committee (reference 303958). The dissemination plan will be decided by the patient and public involvement and engagement (PPIE) group members and study Co-Is, but will target 1) policy makers, and those responsible for commissioning and delivering Long Covid services, 2) patients and the public, and 3) academics.

ABSTRACT

A number of alterations have been identified in lipid metabolism within adipose tissue and liver in obesity. Less is known about the capacity of skeletal muscle for the metabolism of fatty acids in obesity-related insulin resistance, though it is evident that dry cow muscles may contain increased triglyceride content. The current study was therefore undertaken to evaluate the skeletal muscle expression of proteins of the fatty acid metabolism in dry cows with different body condition scores (BCS). Sixteen Holstein-Friesian close-up cows were divided into 2 equal groups based on their BCS as optimal (3.25 ≤ BCS ≤ 3.5) and high (4.0 ≤ BCS ≤ 4.25). Blood samples collection and skeletal muscle biopsies were carried out at day 10 before calving. Blood serum was assayed for concentration of resistin using a bovine specific ELISA. Protein expression of insulin receptor beta subunit (IRß), glucose transporter 4 (GLUT4), fatty acid translocase (FAT/CD36), fatty acid transporter 1 (FATP1), carnitine palmitoyltransferase 1 (CPT1), AMP-acitvated protein kinase (AMPK) and lipin 1 were analyzed in semitendinosus muscle by immunoblot. Resistin differed non-significantly between high-BCS and optimal-BCS cows. Insulin-resistant lipid metabolism in obese cows was paralleled with increased skeletal muscle expression of lipin 1 and GLUT4, and decreased expression of IRß and FATP1. These data suggest that in obesity-related insulin resistance, metabolic capacity in dry cow skeletal muscles appears to be organized towards the synthesis of signaling intermediates rather than fatty acids oxidation and that altered fatty acid uptake does not contribute to this disposition.

ABSTRACT

INTRODUCTION: Despite the widely recognized ethical and practical benefits of community engagement in HIV research, epistemic injustice persists within the field. Namely, the knowledge held by communities disproportionately affected by HIV is systematically afforded less credibility than that of more privileged academic researchers. In order to illustrate what this looks like in practice, we synthesized the extent of reporting on community engagement within recent high-impact HIV intervention research papers. However, we also posit that the HIV research sector has the potential to devise and showcase world-leading examples of equitable research-community partnerships and suggest actionable key steps to achieving this goal. DISCUSSION: In the absence of reporting requirements within the publishing process, it is difficult to infer whether and how the community have been consulted in the design, implementation, analysis and/or interpretation of findings. As an illustrative exercise, we offer a rapid synthesis of the extent of reporting on community engagement in HIV research from 2017 to 2019, which highlighted sporadic and very low rates of reporting of community engagement in recent high-impact HIV intervention studies. Of note is that none of the included studies reported on community engagement through all stages of the research process. There were also discrepancies in how community involvement was reported. We provide three actionable recommendations to enhance reporting on community engagement in HIV research: (1) community-led organizations, researchers and scientific journals should band together to develop, publish and require adherence to standardized guidelines for reporting on community involvement in HIV research; (2) research funders should (continue to) require details about how relevant communities have been engaged prior to the submission of funding requests; and (3) researchers should take proactive measures to describe their engagement with community organizations in a clear and transparent manner. CONCLUSIONS: There is a clear and urgent need for guidelines that facilitate transparent and consistent reporting on community engagement in HIV intervention research. Without standardized reporting requirements and accountability mechanisms within the research sector, the extent of meaningful community engagement cannot be established and may remain a catchphrase rather than reality.

ABSTRACT

We examined the impact of Covid-19 restrictions on the wellbeing and access to care among people living with HIV (PLWH) in the UK. A cross-sectional anonymous online survey was circulated to PLWH attending care at three HIV services in Sussex. The questionnaire covered key themes: socio-demographic characteristics; changes in physical and mental health; accessibility of essential health services and information; and socio-economic concerns. Free-text qualitative responses were examined through framework analysis. Quantitative data from 653 respondents were available, with a subset of 385 free-text qualitative responses. In terms of mental health, 501 (77.6%) respondents reported feeling more anxious; 464 (71.8%) reported feeling more depressed than usual; and 128 (19.8%) reported having suicidal thoughts since the start of the pandemic. Respondents worried about running out of HIV medicine (n = 264, 40.7%); accessing HIV services (n = 246, 38.0%) as well as other health services (n = 408, 63.0%). Widespread resilience was also noted: 537 (83.3%) of respondents felt that living with HIV had equipped them with the strength to adapt to the Covid-19 pandemic. Findings highlight important gaps between the multifaceted needs of PLWH. Multisectoral collaborations and investments are needed to adequately support PLWH and to build resilience to future shocks within HIV services.

ABSTRACT

OBJECTIVE: Data about the dynamics of noradrenaline (NA) transmission, storage and degradation may be very important for understanding the reduction of functional deficiency of NA and maintaining the stability of NA levels in animals with depressive-like behavior treated with lithium. This study aimed to investigate the effects of mood stabilizer lithium on concentrations of NA in the prefrontal cortex (PFC), as well as behavior rats exposed to chronic restraint stress (CRS). In addition, this study examined the effects of lithium on protein levels of noradrenaline transporter (NET), vesicular monoamine transporter 2 (VMAT2) and catechol-O-methyltransferase (COMT), as well as the enzyme activity of monoamine oxidase A (MOA) in the PFC of chronically stressed rats. METHODS: The investigated parameters were quantified by Western blot analysis, CAT Research ELISA kits, and an assay of enzyme activity. Also, the forced swim test (FST) was used to assess the behavior of animals. RESULTS: We found that lithium treatment decreased high protein levels of NET and VMAT2, as well as the enzyme activity of MOA in chronically stressed rats to the levels found in unstressed animals. In addition, lithium treatment decreased the concentration of NA (24%) and immobility in animals exposed to CRS. CONCLUSION: Our data confirm that lithium-induced modulation of prefrontal noradrenergic turnover and stabilized the behavior of chronically stressed rats.

ABSTRACT

ABSTRACTWhilst the HIV response has made significant progress in increasing representation of adults affected by HIV, the meaningful inclusion of children and adolescents has lagged. But this may be a pivotal moment of change. We report on a decade of conducting adolescent advisory groups in South Africa, to reflect on youth advisory processes. Data was collected from 2008 to 2018 from adolescent advisors (n = 60) and researchers (n = 25), and included feedback sessions, social media, anonymous "post-boxes" and interviews. Findings include the value of adolescent involvement in multiple stages of research co-creation and engagement in policy processes, the need for a safe environment and supporting adolescents living in extreme vulnerability. We also discuss the reconfiguring of power and personal relationships, and logistical and financial needs of adolescent advisory groups. Findings suggest that adolescent co-creation of research is feasible, even with very vulnerable adolescents, although ethical considerations need to be carefully addressed. Benefits include increased methodological rigour, enhanced adolescent acceptability of research and the recalibration of research dynamics for the empowerment of their target beneficiaries. Future studies could benefit from meaningfully involving adolescents through youth advisory groups.

ABSTRACT

Increased dietary, blood, and tissue n-6/n-3 fatty acid ratios are associated with obesity and metabolic syndrome. Due to Westernized dietary patterns, the increasing n-6/n-3 ratio is of growing concern worldwide, and dietary strategies aimed at its lowering are of public health importance. Walnuts are rich in dietary fats, and their consumption promotes cardiometabolic health. This study aimed to examine the effect of 6-week walnut consumption on tissue-specific n-6/n-3 ratio and fatty acid metabolic conversion in fructose-fed rats with a cluster of metabolic disorders. Male Wistar rats were fed a standard diet with or without 10% fructose in drinking water for 9 weeks. Diets of half of the animals were then supplemented with walnuts (2.4 g/day) for 6 weeks, upon which fatty acid profiles were determined in plasma, liver, adipose tissue, and kidney total lipids. Results showed that walnuts induced significant decreases in the n-6/n-3 content of total lipid pool in plasma and examined tissues, irrespective of metabolic burden. Walnut intervention decreased plasma and liver palmitoleic/palmitic, arachidonic/linoleic, and docosahexaenoic/α-linolenic acid ratios. It also modulated individual fatty acid levels by reducing arachidonic and palmitic acid and increasing α-linolenic, eicosapentaenoic, and docosapentaenoic acid in plasma and most tissues. Our study demonstrated that 6-week consumption of walnuts favorably modulated n-6/n-3 plasma and tissue ratio in male Wistar rats regardless of high-fructose feeding, underscoring the promising potential of walnuts in both prevention and treatment of the metabolic syndrome.

ABSTRACT

BACKGROUND: Mental health difficulties and mental disorders are common in adolescents living with HIV or who are affected by HIV because of living in HIV-affected households in low- and middle-income (LMICs) countries, but little is known about the interventions that target these individuals and whether they are effective. AIMS: This systematic review aims to address these gaps by examining what has worked and what has not worked to support the mental health of adolescents living with HIV or affected by HIV in low- and middle-income contexts (PROSPERO Number: CRD42018103269). METHOD: A systematic literature review of online databases from the year 2000 to 2018, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, included English-language publications of quantitative evaluations of psychosocial interventions aiming to improve mental health among adolescents living with HIV and adolescents from HIV-affected households (aged 10-24 years) in LMICs. RESULTS: Out of 2956 articles, 16 studies from 8 LMICs met the inclusion criteria. Thirteen studies focused on adolescents affected by HIV and only three studies on adolescents living with HIV. Only five studies included were from Sub-Saharan Africa. Interventions most often used a family-strengthening approach strengthening caregiver-adolescent relationships and communication and some problem-solving in groups or individually. Five studies reported statistically significant changes in adolescent and caregiver mental health or mental well-being, five among adolescents only and two among caregivers only. CONCLUSIONS: Research on what works to improve mental health in adolescents living with HIV in LMIC is in its nascent stages. Family-based interventions and economic strengthening show promise.

ABSTRACT

BACKGROUND: Adolescents living with HIV may be at elevated risk of psychological problems, which are correlated with negative health outcomes. In cross-sectional research with HIV-affected adolescents, bullying victimisation and internalised HIV stigma have been associated with poorer psychological health. We extended these findings and tested longitudinal associations between bullying victimisation, internalised stigma, and mental health among adolescents living with HIV. We also tested whether relationships between bullying victimisation and psychological symptoms were mediated by internalised stigma. METHOD: Adolescents living with HIV (n = 1060, 10-19 years, 55% female), who had ever initiated HIV treatment in 53 public health facilities in the Eastern Cape, South Africa, were interviewed and followed up 18 months later (n = 995, 94% retention). Participants completed well-validated measures of depression, anxiety, posttraumatic stress, bullying victimisation, and internalised stigma. RESULTS: After adjusting for baseline mental health and sociodemographic characteristics, baseline internalised stigma prospectively predicted poorer outcomes on all psychological measures. Bullying victimisation at baseline was not directly associated with any psychological measures at follow up; however, it was indirectly associated with all psychological measures via internalised stigma. LIMITATIONS: Reliance on self-report measures and poor reliability of the depression scale. CONCLUSIONS: Bullying victimisation is associated with internalised stigma, which in turn predicts psychological symptoms over time. Interventions reducing internalised stigma and associated psychological distress are needed, and these should be integrated into HIV care to ensure optimal HIV management. The implementation of bullying prevention programs may reduce internalised stigma and promote mental health among adolescents living with HIV.

ABSTRACT

Capacity development is a process by which individuals, organizations and societies develop abilities to perform functions, solve problems and achieve objectives. This systematic review sought to document capacity development interventions, the associated outcomes and its effectiveness in increasing demand for rights and health services among key populations (KP) in low and middle-income countries. Twenty papers met our review's selection criteria. Significant improvements in health service utilization were achieved in most community mobilization and peer-led interventions. Whilst we found ample evidence linking capacity development to uptake of services, there was a striking dearth of research examining the impact of capacity development on demand for rights among KP. There was inadequate contextual data to explain variations in intervention effectiveness across different projects. More evidence is needed on the impact of capacity development on demand for health services and rights among KP. Consensus on parameters of capacity development and priority outcomes is required.
