RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Internalized HIV stigma is a public health concern as it can compromise HIV prevention, care and treatment. This paper has two aims. First, it highlights the urgent need for research evidence on internalized HIV stigma based on critical knowledge gaps. Here, critical knowledge gaps were identified based on most up-to-date systematic review-level evidence on internalized stigma related to HIV and mental health difficulties. Secondly, the paper calls for a shift in focus of internalized HIV stigma research, one that moves beyond psychological frameworks to integrate social, structural and intersectional conceptualizations of stigma. This part of the paper reviews the evolution of stigma theory since Goffman's 1963 seminal work - which defined stigma - to present. MAIN TEXT: Despite studies consistently suggesting that internalized HIV stigma is more prevalent than enacted stigma, there is little evidence of well-established programs to address it. In addition to this, considerable gaps in basic knowledge about the drivers of internalized HIV stigma hamper the development of an evidence-based response to the problem. The limited intervention and epidemiological research on the topic treats internalized HIV stigma as a purely psychological phenomenon. The second part of the paper provides arguments for studying internalized HIV stigma as a function of social and structural forces: (1) Individual-level interventions for internalized HIV stigma are rooted in out-dated theoretical assumptions; (2) From an ethics point of view, it could be argued that individual-level interventions rely on a victim-centric approach to a public health problem; (3) Social and structural approaches to internalized HIV stigma must be explored due to the high opportunity cost associated with small-scale individual-level interventions. CONCLUSIONS: Critical gaps in intervention and epidemiological research in internalized HIV stigma remain. There has been an absence of a shared, sound theoretical understanding of internalized HIV stigma as a manifestation of social and structural factors. This commentary sought to stimulate a dialogue to remedy this absence. Future research should take into account ethical considerations, the evolution of stigma theory over the past five decades, intersectionality and opportunity cost when framing hypotheses, developing theories of change and designing interventions.

RESUMO

BACKGROUND: Globally, the prevalence of HIV among transgender women is more than 40 times higher than the prevalence in the general reproductive-age adults. They also face intersecting barriers to health, social, and legal services due to their hidden and stigmatized nature. Despite the particular needs, data regarding the access to services among transgender populations is scant globally. This study aims to identify characteristics of transgender women in Cambodia that may determine their accessibility to community-based HIV services. METHODS: In the National Biological and Behavioral Survey 2016, a structured questionnaire was used for face-to-face interviews with 1375 sexually active transgender women recruited from the capital city and 12 other provinces using the Respondent-Driven Sampling method. Weighted multivariate regression analysis was conducted to explore factors associated with access to community-based HIV services. RESULTS: The mean age of the participants was 25.8 years (SD = 7.1), and 45.0% reported having received at least one community-based HIV service in the past three months. Compared to participants who reported not having been reached by any community-based HIV programs, participants who reported having been reached by the programs were significantly more likely to reside in an urban setting (AOR = 1.41, 95% CI = 1.01-1.96), to have used gender-affirming hormones (AOR = 1.50, 95% CI = 1.17-1.92), to have been tested for HIV in the past six months (AOR = 7.42, 95% CI = 5.78-9.53), and to have been arrested by police or other authorities because of their transgender identity (AOR = 1.55, 95% CI = 1.03-2.33). Participants who reported having been reached by community-based HIV programs were significantly less likely to report being in a receptive role (AOR = 0.34, 95% CI = 0.15-0.82), to use condoms consistently with non-commercial male partners (AOR = 0.72, 95% CI = 0.55-0.94), and to perceive that their co-workers were not supportive regarding their transgender identity (AOR = 0.57, 95% CI = 0.44-0.98). CONCLUSIONS: Despite the extensive expansion of community-based HIV programs, less than half of transgender women in this national survey had access to the services. Innovative strategies and culturally sensitive interventions should be put in place to reach and respond to the needs of sub-groups of transgender women who are less likely to be reached by the existing traditional approaches.

RESUMO

Olanzapine, an antipsychotic drug, is used to treat depressive disorder, but its effects on the liver, the main site of drug metabolism, still remain elusive. We studied the effects of 3 weeks of olanzapine treatment (7.5 mg/kg per day) on the malondialdehyde (MDA) and protein carbonyl (PCO) contents, protein expression of copper/zinc superoxide dismutase (CuZnSOD), and activity of total superoxide dismutase (SOD), as well as catalase (CAT) protein expression and activity levels in the liver cytosol of rats exposed to 6 weeks of chronic social isolation (CSIS), which causes depressive- and anxiety-like behaviors. Increased cytosolic MDA in CSIS rats (vehicle- or olanzapine-treated) indicated hepatic oxidative stress. Increase in PCO and CAT activity associated with unchanged total SOD activity following CSIS also confirm the presence of oxidative stress. Chronic olanzapine treatment in CSIS prevented increase in PCO without an effect on MDA content. Increased SOD activity in olanzapine-treated (controls and CSIS) groups compared with corresponding vehicle-treated groups and decreased CAT activity in olanzapine-treated CSIS rats compared with vehicle-treated CSIS group was found. The data suggest that chronic olanzapine treatment has a protective effect on hepatic protein oxidation and improves antioxidant defense. The beneficial effects of olanzapine may be due to its free radical scavenging properties and antioxidant activity.

RESUMO

Despite documented common use of traditional healers and efforts to scale up antiretroviral treatment (ART) in sub-Saharan Africa, evidence on whether medical pluralism predicts ART use is inconclusive and restricted to clinic settings. This study quantitatively assesses whether medical pluralism predicts ART use among parents in need of ART in South Africa. 2,477 parents or primary caregivers of children were interviewed in HIV-endemic communities of KwaZulu-Natal. Analysis used multiple logistic regression on a subsample of 435 respondents in need of ART, who reported either medical pluralism (24.6 %) or exclusive public healthcare use (75.4 %). Of 435 parents needing ART, 60.7 % reported ART use. Medical pluralism emerged as a persistent negative predictor of ART utilization among those needing it (AOR [95 % CI] = .556 [.344 - .899], p = .017). Use of traditional healthcare services by those who need ART may act as a barrier to treatment access. Effective intersectoral collaboration at community level is urgently needed.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.
