Introduction Sexual health remains a public health priority and relies on widely available testing to enable prompt diagnosis and treatment. Technology-based approaches to distribute tests have potential to increase access and enable prompt diagnosis and treatment. We evaluated the acceptability of vending machines (VMs) to distribute HIV self-test (HIVST) and sexually transmitted infection (STI) self-sample kits, from the service user and stakeholder perspective.Methods Six VMs were placed across Brighton and Hove (UK) in publicly accessible locations. After use, individuals received a text with an online questionnaire link. Participants completing the questionnaire were invited to a semistructured interview. Stakeholders were staff on sites where the VM was placed. Data analysis took place on NVivo, using a thematic approach.Results 12 users completed the interview. 42% within the age 18–25 years with equal male and female identifying distributions. 33% were heterosexual, 25% homosexual and 33% bisexual. VM acceptability was high with anonymity and instant access as main benefits. Some participants expressed concern that the public location of the VM may deter others from using it. Participants found the HIVST mouth swabs were acceptable, although there was concern over accuracy. Participants welcomed being able to access comprehensive sexual health screening through a VM. Five stakeholders completed the interview. There was recognition that a publicly visible VM led to positive sexual health conversations between service users and staff. There were initial issues with restocking and machine hardwiring.Conclusions VMs to distribute HIV and STI testing kits is acceptable to service users and stakeholders. The main reported benefits are increased confidentiality, privacy and immediate access. Further education referencing the accuracy of the HIVST mouth swab may alleviate concerns. From a stakeholder perspective, the pathway is beneficial and the role of community champions to reduce stigma is favourable.

Introduction Our aim was to describe episodic nature of disability among adults living with Long COVID.Methods We conducted a community-engaged qualitative descriptive study involving online semistructured interviews and participant visual illustrations. We recruited participants via collaborator community organisations in Canada, Ireland, UK and USA.We recruited adults who self-identified as living with Long COVID with diversity in age, gender, race/ethnicity, sexual orientation and duration since initial COVID infection between December 2021 and May 2022. We used a semistructured interview guide to explore experiences of disability living with Long COVID, specifically health-related challenges and how they were experienced over time. We asked participants to draw their health trajectory and conducted a group-based content analysis.Results Among the 40 participants, the median age was 39 years (IQR: 32–49); majority were women (63%), white (73%), heterosexual (75%) and living with Long COVID for ≥1 year (83%). Participants described their disability experiences as episodic in nature, characterised by fluctuations in presence and severity of health-related challenges (disability) that may occur both within a day and over the long-term living with Long COVID. They described living with ‘ups and downs’, ‘flare-ups’ and ‘peaks’ followed by ‘crashes’, ‘troughs’ and ‘valleys’, likened to a ‘yo-yo’, ‘rolling hills’ and ‘rollercoaster ride’ with ‘relapsing/remitting’, ‘waxing/waning’, ‘fluctuations’ in health. Drawn illustrations demonstrated variety of trajectories across health dimensions, some more episodic than others. Uncertainty intersected with the episodic nature of disability, characterised as unpredictability of episodes, their length, severity and triggers, and process of long-term trajectory, which had implications on broader health.Conclusion Among this sample of adults living with Long COVID, experiences of disability were described as episodic, characterised by fluctuating health challenges, which may be unpredictable in nature. Results can help to better understand experiences of disability among adults living with Long COVID to inform healthcare and rehabilitation.

Medicine - Abstract
Objectives The Short-Form HIV Disability Questionnaire (SF-HDQ) was developed to measure the presence, severity and episodic nature of health challenges across six domains. Our aim was to assess the sensibility, utility and implementation of the SF-HDQ in clinical practice.Design Mixed methods study design involving semistructured interviews and questionnaire administration.Participants We recruited adults living with HIV and HIV clinicians in Canada, Ireland and the USA.Methods We electronically administered the SF-HDQ followed by a Sensibility Questionnaire (face and content validity, ease of usage, format) and conducted semistructured interviews to explore the utility and implementation of the SF-HDQ in clinical practice. The threshold for sensibility was a median score of >5/7 (adults living with HIV) and>4/7 (HIV clinicians) for ≥80% of items. Qualitative interview data were analysed using directed content analysis.Results Median sensibility scores were >5 (adults living with HIV; n=29) and >4 (HIV clinicians; n=16) for 18/19 (95%) items. Interview data indicated that the SF-HDQ represents the health-related challenges of living with HIV and other concurrent health conditions; captures the daily episodic nature of HIV; and is easy to use. Clinical utility included measuring health challenges and change over time, guiding referral to specialists and services, setting goals, facilitating communication and fostering a multidisciplinary approach to care. Considerations for implementation included flexible, person-centred approaches to administration, and communicating scores based on personal preferences.Conclusions The SF-HDQ possesses sensibility and utility for use in clinical settings with adults living with HIV and HIV clinicians in three countries.

Medicine - Abstract
Introduction As the prevalence of Long COVID increases, there is a critical need for a comprehensive assessment of disability. Our aims are to: (1) characterise disability experiences among people living with Long COVID in Canada, UK, USA and Ireland; and (2) develop a patient-reported outcome measure to assess the presence, severity and episodic nature of disability with Long COVID.Methods and analysis In phase 1, we will conduct semistructured interviews with adults living with Long COVID to explore experiences of disability (dimensions, uncertainty, trajectories, influencing contextual factors) and establish an episodic disability (ED) framework in the context of Long COVID (n~10 each country). Using the conceptual framework, we will establish the Long COVID Episodic Disability Questionnaire (EDQ). In phase 2, we will examine the validity (construct, structural) and reliability (internal consistency, test–retest) of the EDQ for use in Long COVID. We will electronically administer the EDQ and four health status criterion measures with adults living with Long COVID, and readminister the EDQ 1 week later (n~170 each country). We will use Rasch analysis to refine the EDQ, and confirm structural and cross-cultural validity. We will calculate Cronbach’s alphas (internal consistency reliability), and intraclass correlation coefficients (test–retest reliability), and examine correlations for hypotheses theorising relationships between EDQ and criterion measure scores (construct validity). Using phase 2 data, we will characterise the profile of disability using structural equation modelling techniques to examine relationships between dimensions of disability and the influence of intrinsic and extrinsic contextual factors. This research involves an academic–clinical–community partnership building on foundational work in ED measurement, Long COVID and rehabilitation.Ethics and dissemination This study was approved by the University of Toronto Research Ethics Board. Knowledge translation will occur with community collaborators in the form of presentations and publications in open access peer-reviewed journals and presentations.

Public aspects of medicine ,RA1-1270 - Abstract
As the response to the HIV epidemic in sub-Saharan Africa continues to mature, a growing number of people living with HIV (PLHIV) are aging and risk for non-communicable diseases increases. Routine laboratory tests of serum creatinine have been conducted to assess HIV treatment (ART) suitability. Here we utilize those measures to assess kidney function impairment among those initiating ART. Identification of non-communicable disease (NCD) risks among those in HIV care creates opportunity to improve public health through care referral and/or NCD/HIV care integration. We estimated glomerular filtration rates (eGFR) using routinely collected serum creatinine measures among a cohort of PLHIV with an HIV care visit at one of 113 Centre for Infectious Disease Research Zambia (CIDRZ) supported sites between January 1, 2011 and December 31, 2017, across seven of the ten provinces in Zambia. We used mixed-effect Poisson regression to assess predictors of eGFR

Medicine ,Science - Abstract
Quality of life (QoL) is recognized as an essential end point in the disease management of chronic conditions such as HIV with calls to include good QoL as a 'fourth 90' in the 90-90-90 testing and treatment targets introduced by World Health Organization in 2016. Cognitive impairments impact a broad spectrum of experiences and are a common issue effecting people living with HIV (PLWH). Despite this, few studies have examined QoL in PLWH who also have a cognitive disorder. This study aimed to synthesize and describe what is known about QoL in those living with HIV-associated neurocognitive disorders (HAND). A scoping review of peer-reviewed literature was conducted to identify how QoL has been investigated and measured in PLWH with HAND, and how PLWH with HAND report and describe their QoL. We searched PsychInfo, Medline, Scopus, and Web of Science along with hand-searching reference lists from relevant studies found. Included studies were those published in English after 1st January 2003 which included PLWH with cognitive impairment not due to other pre-existing conditions. Fifteen articles met criteria for inclusion. Two studies measured QoL as a primary aim, with others including QoL assessment as part of a broader battery of outcomes. The MOS-HIV and SF-36 were the most commonly used measures of overall QoL, with findings generally suggestive of poorer overall QoL in PLWH with HAND, compared to PLWH without cognitive impairment. Studies which examined dimensions of QoL focused exclusively on functionality, level of independence, and psychological QoL domains. There is a considerable dearth of research examining QoL in PLWH with HAND. The initiatives which advocate for healthy aging and improved QoL in PLWH must be extended to include and understand the experiences those also living with cognitive impairment. Research is needed to understand the broad experiential impacts of living with these two complex, chronic conditions, to ensure interventions are meaningful to patients and potential benefits are not missed.

ObjectivesTo investigate the associations of plasma lamivudine (3TC), abacavir (ABC), emtricitabine (FTC) and tenofovir (TFV) concentrations with cognitive function in a cohort of treated people with HIV (PWH).MethodsPharmacokinetics (PK) and cognitive function (Cogstate, six domains) data were obtained from PWH recruited in the POPPY study on either 3TC/ABC or FTC/tenofovir disoproxil fumarate (TDF)-containing regimens. Association between PK parameters (AUC0-24: area under the concentration-time curve over 24 hours, Cmax: maximum concentration and Ctrough: trough concentration) and cognitive scores (standardized into z-scores) were evaluated using rank regression adjusting for potential confounders.ResultsMedian (IQR) global cognitive z-scores in the 83 PWH on 3TC/ABC and 471 PWH on FTC/TDF were 0.14 (-0.27, 0.38) and 0.09 (-0.28, 0.42), respectively. Higher 3TC AUC0-24 and Ctrough were associated with better global z-scores [rho = 0.29 (p = 0.02) and 0.27 (p = 0.04), respectively], whereas higher 3TC Cmax was associated with poorer z-scores [rho = -0.31 (p0.05). None of the FTC and TFV PK parameters were associated with global or domain cognitive scores.ConclusionsWhilst we found no evidence of either detrimental or beneficial effects of ABC, FTC and TFV plasma exposure on cognitive function of PWH, higher plasma 3TC exposures were generally associated with better cognitive performance although higher peak concentrations were associated with poorer performance.

Medicine ,Science - Abstract
BackgroundMusculoskeletal symptoms in people living with HIV (PLWH) such as pain, joint stiffness, and fatigue are commonly reported. Prevalence rates of up to 45%, 79% and 88% respectively have been reported. However, very little is known about differences in prevalence and impact of musculoskeletal symptoms on physical functioning and quality of life of PLWH on effective combined antiretroviral treatment (cART) in high and low-resource settings.MethodsA cross-sectional study of PLWH on effective cART enrolled from two large urban clinics in the UK and Zambia was conducted in 2016. Eligible participants had no history of trauma to the joints within 4 weeks of recruitment, or documented evidence of previous rheumatic disease. Current musculoskeletal symptoms, functional ability, and health-related quality of life were evaluated using the health assessment (HAQ) and quality-of-life short form (SF-36) self-reported questionnaires.Results214 patients were enrolled (108:UK and 106:Zambia). Participants from Zambia were younger (47 vs 44 years) and had significantly lower CD4 counts (640 vs 439 cells/mL p = 0.018) compared to those from the UK, while the UK group had lived with HIV longer (11 vs 6 years; pConclusionsMusculoskeletal symptoms in PLWH from both the UK and Zambia were common. PLWH in the UK reported worse quality of life measures associated with musculoskeletal symptoms compared to those in Zambia, suggesting that factors such as mental health, patient expectations and multimorbidity might play a role in determining well-being and quality of life of PLWH with musculoskeletal symptoms.

- Abstract
Background The Episodic Disability Questionnaire (EDQ) is a generic 35-item patient-reported outcome measure of presence, severity and episodic nature of disability. We assessed the measurement properties of the Episodic Disability Questionnaire (EDQ) with adults living with HIV. Methods We conducted a measurement study with adults living with HIV in eight clinical settings in Canada, Ireland, United Kingdom, and United States. We electronically administered the EDQ followed by three reference measures (World Health Organization Disability Assessment Schedule; Patient Health Questionnaire; Social Support Scale) and a demographic questionnaire. We administered the EDQ only 1 week later. We assessed the internal consistency reliability (Cronbach’s alpha; >0.7 acceptable), and test-retest reliability (Intra Class Correlation Coefficient; >0.7 acceptable). We estimated required change in EDQ domain scores to be 95% certain that a change was not due to measurement error (Minimum Detectable Change (MDC95%)). We evaluated construct validity by assessing 36 primary hypotheses of relationships between EDQ scores and scores on the reference measures (> 75% hypotheses confirmed indicated validity). Results 359 participants completed the questionnaires at time point 1, of which 321 (89%) completed the EDQ approximately 1 week later. Cronbach’s alpha for internal consistency ranged from 0.84 (social domain) to 0.91 (day domain) for the EDQ severity scale, and 0.72 (uncertainty domain) to 0.88 (day domain) for the EDQ presence scale, and 0.87 (physical, cognitive, mental-emotional domains) to 0.89 (uncertainty domain) for the EDQ episodic scale. ICCs for test-retest reliability ranged from 0.79 (physical domain) to 0.88 (day domain) for the EDQ severity scale and from 0.71 (uncertainty domain) to 0.85 (day domain) for the EDQ presence scale. Highest precision was demonstrated in the severity scale for each domain (MDC95% range: 19–25 out of 100), followed by the presence (MDC95% range: 37–54) and episodic scales (MDC95% range:44–76). Twenty-nine of 36 (81%) construct validity hypotheses were confirmed. Conclusions The EDQ possesses internal consistency reliability, construct validity, and test-retest reliability, with limited precision when administered electronically with adults living with HIV across in clinical settings in four countries. Given the measurement properties, the EDQ can be used for group level comparisons for research and program evaluation in adults living with HIV.

Background Cognitive impairment (CI) in people living with HIV (PLWH) is an important health concern in the context of an ageing HIV population. Impacting 14–28% of PLWH, CI is associated with lower health-related quality of life (HRQoL), however, evaluation of the illness-specific factors comprising HRQoL in PLWH with CI have not been assessed. Objective We sought to contribute evidence toward an understanding of HRQoL and identify domains of HRQoL in PLWH with CI. Methods Qualitative interviews with 25 PLWH with objective CI related to HIV disease were conducted with participants attending HIV clinics in the UK. Clinically significant CI was defined based on The European AIDS Clinical Society guidelines, requiring: (i) subjective reporting of cognitive symptoms; (ii) symptoms to be related to HIV (e.g. potentially confounding non-HIV related conditions have been excluded or are being optimally managed) and; (iii) formal neuropsychological assessment confirming CI. Median age was 56 years (range 35–80); 18 participants were men (72%); 11 (44%) were white British and 8 (32%) were Black African; 14 (56%) were men that have sex with men and 10 (40%) were heterosexual; median number of years living with HIV was 17 (range 1–34); and all participants were on combination antiretroviral therapy. Analyses employed techniques from grounded theory, underpinned by an inductive, collaborative team-based approach. Results Findings revealed seven interrelated domains comprising HRQoL experiences were identified: Physical function, Cognition, Social connectedness, Physical and mental health, Stigma, Self-concept, and Control and acceptance, and each was defined by specific descriptive components. Conclusion This study provides valuable insights on the factors that drive HRQoL in PLWH with CI and contribute to a body of evidence which provides targets for the development of targeted interventions to maintain or improve quality of life.

Objective: To evaluate frailty, falls and perceptions of ageing among clinically stable individuals with HIV, engaged with remote healthcare delivered via a novel smartphone application. Methods: This was a multi-centre European cross-sectional, questionnaire-based sub-study of EmERGE participants. Frailty was assessed using the five-item FRAIL scale. Present criteria were summed and categorized as follows: 0, robust; 1-2, pre-frail; 3-5, frail. Falls history and EQ-5D-5L quality of life measure were completed. Participants were asked their felt age and personal satisfaction with ageing. Results: A total of 1373 participated, with a mean age of 45 (± 9.8) years. Frailty was uncommon at 2%; 12.4% fell in the previous year, 58.8% of these recurrently. Mood symptoms and pain were prevalent, at 43.3% and 31.8%, respectively. Ageing satisfaction was high at 76.4%, with 74.6% feeling younger than their chronological age; the mean felt age was 39.3 years. In multivariable analysis, mood symptoms and pain were positively associated with frailty, falls and ageing dissatisfaction. An increase in pain severity and mood symptoms were respectively associated with 34% and 63% increased odds of pre-frailty/frailty. An increment in pain symptoms was associated with a 71% increase in odds of falling. Pain was associated with ageing poorly, as were mood symptoms, with odds of dissatisfaction increasing by 34% per increment in severity. Conclusions: Although uncommon, frailty, falls and ageing dissatisfaction were seen in a younger cohort with medically stable HIV infection using a remote care model, promoting screening as advocated by European guidelines. These were more common in those with pain or mood symptoms, which should be proactively managed in clinical care and explored further in future research. info:eu-repo/semantics/publishedVersion

- Abstract
BackgroundSyphilis is a sexually transmitted bacterial infection caused byTreponema pallidumsubspeciespallidum, with approximately 6.3 million annual cases globally. Over the last decade, syphilis rates have risen dramatically in many high-income countries, including in England, which has seen a greater than 150% increase. Although this increase is known to be associated with high risk sexual activity in gay, bisexual and other men who have sex with men (GBMSM), cases are rising in heterosexual men and women, and congenital syphilis cases are now seen annually. The transmission dynamics within and between sexual networks of GBMSM and heterosexuals are not well understood.MethodsTo determine if whole genome sequencing could be used to identify discrete patterns of transmission, we linked national patient demographic, geospatial and behavioural metadata to wholeT. pallidumgenome sequences previously generated from 237 patient samples collected from across England between 2012 and 2018.FindingsPhylogenomic analysis and clustering revealed two of the eightT. pallidumsublineages detected in England dominated. These dominant sublineages exhibited different spatiotemporal trends linked to demography or behaviour, suggesting they represent different sexual networks: sublineage 1 was found throughout England and across all patient groups, whereas sublineage 14 occurred predominantly in older GBMSM and was absent from samples sequenced from the North of England. By focussing on different regions of England we were able to distinguish a local heterosexual transmission cluster from a background of transmission amongst GBMSM.InterpretationThese findings demonstrate that despite extremely close genetic relationships betweenT. pallidumgenomes globally, genomics can still be used to identify putative transmission clusters for epidemiological follow-up, and therefore has a role to play in informing public health interventions.FundingWellcome funding to the Sanger Institute (#206194 and 108413/A/15/D), UKRI and NIHR (COV0335; MR/V027956/1, NIHR200125), the EDCTP (RIA2018D-249), and UKHSA.Research in ContextEvidence before this studyDetailed phylogenomic analyses investigating the epidemiology and transmission dynamics ofTreponema pallidumare challenging due to low bacterial loads in clinical specimens, and difficulty in culturing the bacteria. We searched PubMed until August 9th2022 using the search terms “Syphilis” or “Treponema pallidum” and “genomic” or “genome(s)” or “sequencing”, finding 23 studies describing whole genome sequencing ofT. pallidumsubspeciespallidum, of which two used whole genome phylogenies to investigate sexual network epidemiology, with one large study of sexual networks conducted primarily in Victoria, Australia which characterised two major circulating sublineages in that setting, as well as putative sexual transmission networks with distinct sexual behavioural characteristics and potential bridging between networks.Added value of this studyIn this study, we linked national surveillance data toT. pallidumgenomes, and characterised the transmission dynamics of syphilis using samples from across a whole country, in a European setting (England). Integration of national-level sociodemographic, spatiotemporal and genomic data allowed the delineation of putative sexual networks at both the national and region levels, and revealed patterns not previously detected using epidemiological or genomic data alone.Implications of all the available evidenceOur findings are consistent with findings in Australia that demonstrate genomics can identify putative sociodemographic transmission clusters. However, in that study genomic clusters included samples separated by multiple single nucleotide polymorphisms, which could represent several years of evolution. Our study explored the value of linking identical genomes, and highlights that despite technical constraints, whole genome sequencing can be used to enable outbreak exclusion and identify putative local transmission clusters for epidemiological follow-up.

As life expectancy in people living with HIV (PLWH) has increased, the focus of management has shifted to preventing and treating chronic illnesses, but few services exist for the assessment and management of these individuals. Here, we provide an initial description of a geriatric service for people living with HIV and present data from a service evaluation undertaken in the clinic. We conducted an evaluation of the first 52 patients seen in the clinic between 2016 and 2019. We present patient demographic data, assessment outcomes, diagnoses given, and interventions delivered to those seen in the clinic. The average age of attendees was 67. Primary reasons for referral to the clinic included management of complex comorbidities, polypharmacy, and suspected geriatric syndrome (falls, frailty, poor mobility, or cognitive decline). The median (range) number of comorbidities and comedications (non-antiretrovirals) was 7 (2–19) and 9 (1–15), respectively. All attendees had an undetectable viral load. Geriatric syndromes were observed in 26 (50%) patients reviewed in the clinic, with frailty and mental health disease being the most common syndromes. Interventions offered to patients included combination antiretroviral therapy modification, further health investigations, signposting to rehabilitation or social care services, and in-clinic advice. High levels of acceptability among patients and healthcare professionals were reported. The evaluation suggests that specialist geriatric HIV services might play a role in the management of older people with HIV with geriatric syndromes.

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.

Objectives\ud Polypharmacy in people living with HIV (PLWH) increases the risks of medicine-related problems (events or circumstances involving drug therapy that actually or potentially interfere with desired health outcomes). We aimed to examine the feasibility and acceptability of a Medicines Management Optimisation Review (MOR) toolkit in HIV outpatients.\ud \ud Methods\ud This was a multi-centre randomized controlled study across four HIV centres. In all, 200 PLWH on combination antiretroviral therapy, either > 50 years old or < 50 years with other comorbidities, were enrolled to have a MOR or received standard pharmaceutical care. The primary outcome was the difference in the number of medicine-related problems (MRPs) between intervention and standard care groups at baseline and 6 months. Acceptability, cost of the intervention and health-related quality of life were also examined.\ud \ud Results\ud In all, 164 patients were analysed: 70 in the intervention group and 94 in the standard care group. A significant number of MRPs were detected in those patients receiving MOR compared with the standard care group at baseline (93 vs. 2; p = 0.001, z = −8.6, r = 0.6) and 6 months (33 vs. 3; p = 0.001, z = −5.7, r = 0.4). A significant reduction in the number of new MRPs at 6 months in the intervention group versus baseline was also observed (p = 0.001, Z = −3.7, r = 0.2); 44% of MRPs were fully resolved at baseline and 51% at 6 months. No changes in health-related quality of life following MOR or between MOR and standard care groups were observed. The MORs were highly acceptable among patients and healthcare professionals.\ud \ud Conclusions\ud The MOR toolkit was feasible and acceptable, suggesting that HIV outpatient services might consider implementing MOR for targeted populations under their care.

ObjectivesThe Short-Form HIV Disability Questionnaire (SF-HDQ) was developed to measure the presence, severity and episodic nature of health challenges across six domains. Our aim was to assess the sensibility, utility and implementation of the SF-HDQ in clinical practice.DesignMixed methods study design involving semistructured interviews and questionnaire administration.ParticipantsWe recruited adults living with HIV and HIV clinicians in Canada, Ireland and the USA.MethodsWe electronically administered the SF-HDQ followed by a Sensibility Questionnaire (face and content validity, ease of usage, format) and conducted semistructured interviews to explore the utility and implementation of the SF-HDQ in clinical practice. The threshold for sensibility was a median score of >5/7 (adults living with HIV) and>4/7 (HIV clinicians) for ≥80% of items. Qualitative interview data were analysed using directed content analysis.ResultsMedian sensibility scores were >5 (adults living with HIV; n=29) and >4 (HIV clinicians; n=16) for 18/19 (95%) items. Interview data indicated that the SF-HDQ represents the health-related challenges of living with HIV and other concurrent health conditions; captures the daily episodic nature of HIV; and is easy to use. Clinical utility included measuring health challenges and change over time, guiding referral to specialists and services, setting goals, facilitating communication and fostering a multidisciplinary approach to care. Considerations for implementation included flexible, person-centred approaches to administration, and communicating scores based on personal preferences.ConclusionsThe SF-HDQ possesses sensibility and utility for use in clinical settings with adults living with HIV and HIV clinicians in three countries.

People living with HIV are an ageing population with an increasing prevalence of frailty. Management of frailty requires assessment, communication and information sharing with patients. However, evidence regarding the meaning of frailty for this population, and the acceptability of frailty screening, is limited. This study aimed to explore the perceptions of older people living with HIV and HIV professionals towards frailty and routine screening for frailty.Data collection consisted of in-depth individual qualitative interviews with older people living with HIV and focus groups with HIV professionals purposively sampled from outpatient HIV clinics in London and Brighton, UK. Verbatim pseudonymised transcripts were analysed using reflexive thematic analysis supported by NVivo.A total of 45 people living with HIV were interviewed, and 12 HIV professionals participated in two focus groups. Frailty was described as a series of losses around mobility, social inclusion, independence and mental acuity, which could happen at any age. Regarding language, for people living with HIV, explicitly using the word frail was acceptable during screening when approached sensitively and alongside provision of information and support to slow the progression of frailty. However, HIV professionals described concerns about using the word frail for fear of causing distress or offence.Professionals described frailty in terms of functional deficits, whereas people living with HIV described a loss of personhood. Although there is a clear desire among people living with HIV to be informed of their frailty status, approaching conversations about frailty with understanding and compassion is vital. To gain the most from the screening, it is essential that frailty status is shared alongside a clear plan of actionable steps in their care.

Background: In Japan, most new HIV cases are reported amongst men who have sex with men (MSM); thus, there is an urgent need for further widespread testing of MSM. The use of Digital Vending Machines (DVM) in the UK offering HIV test kits targeting MSM show promising results. Digital Vending Machines could be useful to promote and increase the uptake of testing in Japan, although no studies have yet been conducted. We aimed to assess the acceptability and feasibility of distributing HIV test kits using DVMs exploring needs and concerns as well as preferred types of test kits and locations. Methods: Fifty-four individuals participated in workshops and meetings with a further 224 MSM answering a quantitative survey assessing HIV testing and prevention needs. Results: Amongst MSM who had never been tested, 73% showed willingness to purchase tests from DVMs. Responses were broadly positive about DVMs but there were concerns regarding being seen receiving test kits from the machines and linkage to confirmatory testing and appropriate care. Conclusions: Using DVMs to distribute HIV test kits in Japan was found to be both acceptable and feasible and may have the potential to increase access to testing for MSM. Future large-scale evaluation studies are required.

ObjectivesTo describe episodic nature of disability among adults living with Long COVID.MethodsWe conducted a community-engaged qualitative descriptive study involving online semi-structured interviews and participant visual illustrations. We recruited participants via collaborator community organizations in Canada, Ireland, United Kingdom, and United States.ParticipantsAdults who self-identified as living with Long COVID. We purposively recruited for diversity in age, gender, race/ethnicity, sexual orientation, and duration since initial COVID-19 infection.Main Outcome Measure(s)We used a semi-structured interview guide to explore experiences of disability living with Long COVID, specifically health-related challenges and how they were experienced over time. We asked participants to draw their health trajectory and conducted a group-based content analysis.ResultsAmong the 40 participants, the median age was 39 years (interquartile range: 32, 49); majority were women (63%), white (73%), heterosexual (75%), and living with Long COVID for ≥1 year (83%). Participants described their disability experiences as episodic in nature, characterized by fluctuations in presence and severity of health-related challenges (disability) that may occur both within a day and over the long-term living with Long COVID. They described living with ‘ups and downs’, ‘flare-ups’, and ‘peaks’ followed by ‘crashes’, ‘troughs’, and ‘valleys’, likened to a ‘yo-yo’ ‘rolling hills’, and ‘rollercoaster ride’ with ‘relapsing/remitting’, ‘waxing/waning’, ‘fluctuations’ in health. Drawn illustrations demonstrated variety of trajectories across health dimensions, some more episodic than others. Uncertainty intersected with the episodic nature of disability, characterized as unpredictability of episodes, their length, severity and triggers, and process of long-term trajectory, which had implications on broader health.ConclusionsAmong this sample of adults living with Long COVID, experiences of disability were described as episodic, characterized by fluctuating health challenges, which may be unpredictable in nature. Results help to better understand experiences of disability among adults living with Long COVID to inform healthcare and rehabilitation.KEY MESSAGESWhat is already known on this topic:Globally, a growing number of individuals are living with persistent and prolonged signs and symptoms following infection consistent with COVID-19, referred to as Long COVID, Post COVID-19 Condition (PCC) or Post-acute sequelae of SARS-CoV2 (PASC). Individuals living with Long COVID are experiencing a range of symptoms and impairments that impact their ability to carry out day to day activities or engage in social and community life roles.What this study adds:Disability living with Long COVID was described as episodic, characterized by fluctuations in presence and severity of health related challenges, which may be unpredictable in nature, occurring both within the day, and over the long-term of months and years living with Long COVID.How this study might affect research, practice or policy:Results will help researchers, healthcare providers, policymakers, employers, and community members to better understand experiences of disability among adults living with Long COVID, to inform future disability measurement, health and rehabilitation care and service delivery, programs and policies for insurance, return to work, and workplace accommodations.

Objective: To investigate the prevalence of widespread pain among people with HIV (PWH) and describe associations with antiretroviral therapy (ART) and markers of HIV disease stage. Design: Cross-sectional analysis of cohort study in the United Kingdom and Ireland. Methods: Pain information was collected during the baseline visit (conducted from 2013 to 2015) through a self-completed manikin identifying pain at 15 sites from five body regions. Pain was classified as widespread if reported at at least four regions and at least seven sites, or regional otherwise. Chi-squared tests, Kruskal–Wallis tests and ordinal logistic regression were used to consider associations between pain extent and sociodemographic and HIV-related factors. Results: Among the 1207 participants (614 PWH ≥ 50 years, 330 PWH < 50 years, 263 HIV-negative controls ≥50 years), pain was most commonly reported at the upper (left: 28.9%, right: 28.0%) and lower (left: 25.7%; right: 24.5%) leg, upper (18.6%) and lower (29.7%) back and shoulders (left: 16.0%; right: 16.8%). Widespread pain was more commonly reported in PWH than in HIV-negative controls (PWH ≥ 50 years: 18.7%; PWH < 50 years: 12.7%; HIV-negative ≥50 years: 9.5%) with regional pain reported in 47.6, 44.8 and 49.8%, respectively (global P = 0.001). In multivariable analyses, pain extent was greater in those with lower educational attainment, those exposed to more ART drugs, and those with a higher current CD4+ cell count but longer exposure to immunosuppression. Conclusion: Widespread pain is commonly reported in PWH and is associated with longer duration of exposure to HIV, immunosuppression and ART. Our findings call for greater awareness, and interventions to support the management, of pain in PWH.

OBJECTIVE This review will explore how point-of-care tests for sexually transmitted infections have been implemented into health care systems in low- and middle-income countries, and the facilitators and barriers to implementation. INTRODUCTION Sexually transmitted infections contribute to significant global morbidity. In low- and middle-income countries, syndromic management of sexually transmitted infections is recommended. However, due to the limitations of syndromic management, there is increasing interest in the potential for point-of-care tests to be incorporated into models of care for sexually transmitted infections in low-resource settings. It is therefore important to explore how point-of-care tests for sexually transmitted infections have been used in these settings previously, and the facilitators and barriers to implementation on a wider scale. INCLUSION CRITERIA This scoping review will consider studies that explore the use of point-of-care-testing for chlamydia, gonorrhea, trichomoniasis, or syphilis, and how they are implemented into models of care in low- and middle-income countries. Study participants may be those receiving sexually transmitted infection testing or health care professionals providing testing. HIV testing will not be covered. Quantitative, qualitative, and mixed methods study designs, as well as review papers will be considered for inclusion. METHODS The proposed scoping review will be conducted in accordance with JBI methodology for scoping reviews. The authors will search databases including MEDLINE, Embase, Emcare, CINAHL, Scopus, LILACS, African Index Medicus, and the Cochrane library from 1998 onwards. Results will be screened by two independent reviewers and data extracted using a data extraction tool developed by the reviewers. Data will be presented both narratively and in tabular form.

The aims of the study were to describe the prevalence of obesity in the Pharmacokinetic and Clinical Observations in People over Fifty (POPPY) cohort, to identify demographic, clinical and HIV-specific factors associated with obesity, and to characterize the association between obesity and sociodemographic, clinical and HIV-specific factors and quality of life (QoL).A cross-sectional analysis was carried out of baseline data from the three groups ["older" people with HIV infection (PWH) aged ≥ 50 years, "younger" PWH aged50 years and HIV-negative controls aged ≥ 50 years] within the POPPY cohort. Obesity was defined as a body mass index (BMI) 30 kg/mA total of 1361 subjects were included in the study, of whom 335 (24.6%) were obese. The prevalence of obesity was higher in controls (22.3%) than in older (16.8%) and younger (14.2%) PWH, with no differences between the two groups of PWH. Factors associated with obesity were older age, female gender, black African ethnicity and alcohol consumption. Recreational drug use and a higher current CD4 T-cell count (in PWH) were associated with lower and higher odds of being obese, respectively. The presence of obesity was associated with worse physical health QoL scores, higher odds of having cardiovascular disease, type 2 diabetes and hypertension, but lower odds of having osteopenia/osteoporosis, irrespective of HIV status.Despite a lower prevalence of obesity in PWH, specific subgroups (women, people of black African origin and older people) were more likely to be obese, and negative health consequences of obesity were evident, regardless of HIV status. Whether targeted preventive strategies can reduce the burden of obesity and its complications in PWH remains to be determined.

Associations between markers of liver and renal dysfunction and nucleotide reverse transcriptase inhibitor plasma exposure are ill-defined. As part of a large cohort study (Pharmacokinetic and Clinical Observations in People over Fifty), we analysed associations between alanine aminotransferase and estimated glomerular filtration rate results in people living with HIV on tenofovir disoproxil fumarate, emtricitabine, abacavir and lamivudine. While we found no associations between nucleotide reverse transcriptase inhibitor concentrations and alanine aminotransferase, lower estimated glomerular filtration rate values were associated with greater tenofovir, emtricitabine and lamivudine exposure, whereas abacavir showed no associations.

People living with HIV are ageing with a combination of physical, mental and social health challenges, known as disability. Although rehabilitation can address disability, the field is still emerging. Our aim was to identify similar disability experiences across complex chronic conditions and establish recommendations for future rehabilitation research and practice to advance healthy ageing with HIV. We conducted a consultation with 77 stakeholders from the United Kingdom, Canada, and Ireland with expertise in the fields of rehabilitation and HIV, cancer, cardiovascular disease, renal disease, or chronic obstructive pulmonary disease who attended a one-day symposium. We used facilitated discussions to identify how rehabilitation issues in complex chronic disease translate to people ageing with HIV, and prioritised recommendations for future practice and research. Disability issues experienced across HIV and other complex chronic diseases included: (i) frailty, (ii) uncertainty and worrying about the future ageing with complex chronic disease, (iii) mental health, (iv) pain, and (v) stigma. We highlight six recommendations for clinical practice and research to advance healthy ageing with HIV. Opportunities for cross-collaboration exist with other more established areas of chronic disease management and rehabilitation. Recommendations can be used to inform future HIV clinical practice and research in this emerging field.

Background Sexually transmitted infections (STIs) in low- and middle-income countries (LMICs) are predominantly managed by syndromic management. However, most STIs are asymptomatic. These untreated STIs cause individual morbidity, and lead to high STI prevalences. There is increasing interest in the use of point-of-care tests (POCTs) for STIs in LMICs, which could facilitate same day testing and treatment. To best utilise these tests, we must understand the facilitators and barriers to their implementation. The aim of this review is to explore how point-of-care testing for STIs has been implemented into healthcare systems in LMIC and the facilitators and barriers to doing so. Methods A scoping review was conducted by searching MEDLINE, Embase, Emcare, CINAHL, Scopus, LILACS, the Cochrane Library, and ProQuest Dissertations and Theses for studies published between 1st January 1998 and 5th June 2020. Abstracts and full articles were screened independently by two reviewers. Studies were considered for inclusion if they assessed the acceptability, feasibility, facilitators, or barriers to implementation of point-of-care testing for chlamydia, gonorrhoea, trichomoniasis or syphilis in LMICs. Thematic analysis was used to analyse and present the facilitators and barriers to point-of-care STI testing. Results The literature search revealed 82 articles suitable for inclusion; 44 (53.7%) from sub-Saharan Africa; 21 (25.6%) from Latin American and the Caribbean; 10 (12.2%) from East Asia and the Pacific; 6 (7.3%) from South Asia; and one (1.2%) multi-regional study. Thematic analysis revealed seven overarching themes related to the implementation of POCTs in LMICs, namely (i) Ideal test characteristics, (ii) Client factors, (iii) Healthcare provision factors, (iv) Policy, infrastructure and health system factors, (v) Training, audit, and feedback, (vi) Reaching new testing environments, and (vii) Dual testing. Conclusion Implementation of POCTs in LMICs is complex, with many of the barriers due to wider health system weakness. In addition to pressing for broader structural change to facilitate basic healthcare delivery, these themes may also be used as a basis on which to develop future interventions. The literature was heavily skewed towards syphilis testing, and so more research needs to be conducted assessing chlamydia, gonorrhoea, and trichomoniasis testing, as well as home or self-testing.

Objectives\ud To describe the impact that the COVID-19 pandemic has had on HIV testing in Brighton and Hove, United Kingdom.\ud \ud Methods\ud All HIV tests performed in Brighton and Hove from January 2016 to June 2021 were extracted, de-duplicated and anonymized. Analysis was performed to compare the monthly numbers of tests and diagnoses before and during the pandemic across different services.\ud \ud Results\ud The number of patients having tests for HIV in sexual health services (SHS) decreased by 64% in April 2020, followed by a recovery to baseline levels by the start of 2021. Similarly, the monthly number of diagnoses decreased drastically after April 2020, with almost half of diagnoses made by SHS in 2020 occurring in the three pre-pandemic months of the year. ‘Self-sampling’, used more by women and younger patients, has contributed significantly to the recovery.\ud \ud The number of patients tested in secondary care was seemingly unaffected by the pandemic. However, testing numbers were reduced in specialist services, whereas in the emergency department (ED) testing increased four-fold (most notably in the elderly) without finding any cases.\ud \ud General practice saw decreases in both the number of HIV tests performed and the number of new diagnoses made, which had not returned to baseline by June 2021.\ud \ud Discussion\ud The COVID-19 pandemic has had a large impact on the number of HIV tests performed in Brighton and Hove with sizeable decreases in the number of patients tested likely leading to ‘missed’ diagnoses. By June 2021 testing had still not returned to normal across the city.

This study aimed to validate and assess a comprehensive set of illness-specific health-related quality of life (HRQL) domains in people living with HIV (PLWH) with cognitive symptoms. One hundred and three HIV patients with cognitive symptoms ( n = 93 male, 90.3%) were identified from two UK HIV clinics and complete a series of validated scales measuring seven HRQL domains identified as important to HRQL by PLWH with cognitive impairment. These included: physical functioning, cognition, social connectedness, self-concept, HIV stigma, acceptance of and perceived control over cognitive health, and physical and mental health and wellbeing. Exploratory factor analysis confirmed that domain total scores loaded onto one main factor, representing HRQL. Scale cut-off scores revealed a significant proportion of patients scored outside the normal range on single domains (between 26.2% and 79.6%), and many patients on multiple domains (40.8% on 4 or more domains). We found evidence of poor HRQL across domains in the majority of PLWH with cognitive symptoms and identified domains driving these experiences. This provides targets for intervention development and clinical action to maintain or improve HRQL in PLWH with cognitive symptoms or impairment.

We investigated the correlations and agreement between cognitive assessments made using a computerised (CogState™, six domains) and a standard pen-and-paper battery (five domains) in PWH and lifestyle-similar HIV-negative individuals. Demographically adjusted domain and global T-scores were obtained and used to define cognitive impairment according to the multivariate normative comparison (MNC) criteria. Correlations between T-scores and the agreement between the classifications of cognitive impairment obtained from the two batteries were assessed using the Spearman’s rank correlation and Cohen’s κ, respectively. The correlation between global T-scores from the two batteries was 0.52 (95% CI 0.44–0.60) in PWH and 0.45 (0.29–0.59) in controls (p = 0.38 for their difference). Correlations were generally stronger between domains within the same battery than between those from different batteries. The agreement between the two batteries in classifying individuals as cognitively impaired or not impaired was fair in PWH (κ = 0.24) and poor in HIV-negative individuals (κ = −0.02). The moderate correlation between overall cognitive function and the modest agreement between binary classifications of cognitive impairment obtained from two different batteries indicate the two batteries may assess slightly different components of cognition.

We describe the case of a 30-year-old care home employee diagnosed with COVID-19 and acute untreated HIV-1. He was unable to return to work for 119 days due to concerns over transmission risk as his SARS-CoV-2 PCR remained detectable. This highlights the uncertainty in interpreting SARS-CoV-2 PCR results post-infection in acute untreated HIV.

Objectives:\ud Older people living with HIV (PLWH) have higher rates of multimorbidity, polypharmacy and an associated increased risk of potential drug–drug interactions (DDIs). We describe the development, implementation and evaluation of an intervention to increase community prescribers’ access to specialist prescribing advice. \ud Methods: \ud Phase One: a survey evaluating General Practitioners’ (GPs’) knowledge of, and confidence detecting DDIs affecting PLWH, was circulated to eight General Practices in one UK city. Phase Two: co-production was used to develop the THINK ARV intervention for prescribers in city-wide General Practices: a dedicated mobile phone and e-mail advice service staffed by HIV specialist pharmacists. Queries were audited for 6 months pre- and post-intervention. A user-satisfaction survey was emailed to enquirers. \ud \ud Results: \ud Phase One: 42 GPs responded, of whom 62% requested further support identifying DDIs among PLWH. Phase Two: the number of queries received increased from 25 (6 months before ‘THINK ARV’ launch) to 63 in the following 6 months (152% increase). 94% of the queries were specifically about DDIs. \ud \ud Conclusions: \ud Increasing community prescribers’ access to specialist telephone and e-mail advice resulted in increased awareness and detection of DDIs. Similar interventions could be embedded within different healthcare settings to optimise medicines and avoid potential patient harm.

Syphilis is an important sexually transmitted infection caused by the bacterium Treponema pallidum subspecies pallidum. The last two decades have seen syphilis incidence rise in many high-income countries, yet the evolutionary and epidemiological relationships that underpin this are poorly understood, as is the global T. pallidum population structure. We assembled a geographically and temporally diverse collection of clinical and laboratory samples comprising 726 T. pallidum genomes. We used detailed phylogenetic analysis and clustering to show that syphilis globally can be described by only two deeply branching lineages, Nichols and SS14. We show that both of these lineages can be found circulating concurrently in 12 of the 23 countries sampled. To provide further phylodynamic resolution we subdivided Treponema pallidum subspecies pallidum into 17 distinct sublineages. Importantly, like SS14, we provide evidence that two Nichols sublineages have expanded clonally across 9 countries contemporaneously with SS14. Moreover, pairwise genome analysis showed that recent isolates circulating in 14 different countries were genetically identical in their core genome to those from other countries, suggesting frequent exchange through international transmission pathways. This contrasts with the majority of samples collected prior to 1983, which are phylogenetically distinct from these more recently isolated sublineages. Bayesian temporal analysis provided evidence of a population bottleneck and decline occurring during the late 1990s, followed by a rapid population expansion a decade later. This was driven by the dominant T. pallidum sublineages circulating today, many of which are resistant to macrolides. Combined we show that the population of contemporary syphilis in high-income countries has undergone a recent and rapid global expansion.

Objectives To investigate the associations of plasma lamivudine (3TC), abacavir (ABC), emtricitabine (FTC) and tenofovir (TFV) concentrations with cognitive function in a cohort of treated people with HIV (PWH). Methods Pharmacokinetics (PK) and cognitive function (Cogstate, six domains) data were obtained from PWH recruited in the POPPY study on either 3TC/ABC or FTC/tenofovir disoproxil fumarate (TDF)-containing regimens. Association between PK parameters (AUC0-24: area under the concentration-time curve over 24 hours, Cmax: maximum concentration and Ctrough: trough concentration) and cognitive scores (standardized into z-scores) were evaluated using rank regression adjusting for potential confounders. Results Median (IQR) global cognitive z-scores in the 83 PWH on 3TC/ABC and 471 PWH on FTC/TDF were 0.14 (-0.27, 0.38) and 0.09 (-0.28, 0.42), respectively. Higher 3TC AUC0-24 and Ctrough were associated with better global z-scores [rho = 0.29 (p = 0.02) and 0.27 (p = 0.04), respectively], whereas higher 3TC Cmax was associated with poorer z-scores [rho = -0.31 (p0.05). None of the FTC and TFV PK parameters were associated with global or domain cognitive scores. Conclusions Whilst we found no evidence of either detrimental or beneficial effects of ABC, FTC and TFV plasma exposure on cognitive function of PWH, higher plasma 3TC exposures were generally associated with better cognitive performance although higher peak concentrations were associated with poorer performance.

Background: \ud Imaging with β-amyloid (Aβ) positron emission tomography (PET) has the potential to aid the diagnosis of the cause of cognitive impairment affecting people living with HIV (PLWH) when neurodegenerative disorders are considered. We evaluated the clinical utility of [18F]Florbetaben (FBB) in PLWH with cognitive symptoms.\ud \ud Methods: \ud Imaging with FBB PET was performed in 20 patients with cognitive concerns about dementia. Neuropsychological testing, plasma neurofilament light protein, plasma Aβ40, Aβ42, and cerebrospinal fluid Aβ42, tau, and HIV RNA were obtained. FBB PET images were assessed visually by 3 readers blinded to the clinical diagnosis and quantitatively by obtaining a composite cortical to cerebellar cortex standardized uptake value ratio (SUVR). FBB SUVR from 10 age-matched healthy controls was compared with SUVR of PLWH.\ud \ud Results: \ud Most participants were men (90%) of white ethnicity (90%) with a median age (interquartile range) of 59 (43–79) years. Median CD4 count was 682 (74–1056). All patients were on combination antiretroviral therapy with plasma and cerebrospinal fluid HIV RNA

As life expectancy in people living with HIV (PWH) has increased, the focus of management has shifted to preventing and treating chronic illnesses. Regular physical activity (PA) has been shown to reduce the impact of HIV on both physical and mental health. Our objectives were to assess the PA levels of PWH compared to HIV negative controls; investigate factors associated with PA; and determine the effect of PA levels on quality of life and mental well-being. We recruited 110 PWH and 110 HIV negative controls in this cross-sectional, single-centre study. Physical activity, quality of life and mental well-being were assessed using the rapid assessment of physical activity tool, EQ-5D-5L Questionnaire, and the Warwick-Edinburgh Mental Well-being Score. Binary logistic regression and multiple linear regression were used to identify factors associated with PA levels and mental well-being scores respectively. PWH were less likely to meet the WHO-recommended PA requirements compared to controls (50.0% vs. 64.5%; p = 0.041) and had significantly lower mental wellbeing and quality of life scores. Additionally, in PWH higher PA levels were associated with improved self-rated quality of life scores (p = 0.027). Our results suggest that targeted exercise programmes could have a beneficial effect on health status in PWH.

OBJECTIVES The aim of this study was to evaluate the agreement between self-reported sleep measures and insomnia with objectively measured sleep parameters in people with HIV (PWH) and HIV-negative individuals. DESIGN A cross-sectional analysis of PWH and lifestyle-similar HIV-negative individuals. METHODS Self-reported measures included time spent in bed, sleep onset latency and a validated insomnia questionnaire. Objective measures were assessed via 7-days/nights of actigraphy data to determine average and intra-individual variability of several sleep measures (including time spent in bed and onset latency). Spearman's correlation coefficient and Cohen's κ were used to assess the agreement between self-reported and actigraphy-assessed measures. Associations between insomnia and actigraphy-assessed sleep parameters were evaluated using partial least-square discriminant analysis (PLS-DA). RESULTS We found fair correlation between self-reported and actigraphy-assessed time spent in bed in 342 PWH (rs = 0.46) and 119 HIV-negative individuals (rs = 0.48). Among PWH, the correlation did not differ by age, education, depressive symptoms and self-reported insomnia (all P > 0.05), but was stronger in men (P = 0.05) and in those with a BMI of at least 25 kg/m2 (P

Study Objectives We investigated associations between actigraphy-assessed sleep measures and cognitive function in people with and without HIV using different analytical approaches to better understand these associations and highlight differences in results obtained by these approaches. Methods Cognitive and 7-day/night actigraphy data were collected from people with HIV (PWH) and lifestyle-similar HIV-negative individuals from HIV and sexual health clinics in the United Kingdom/Ireland. A global cognitive T-score was obtained averaging the standardized individual cognitive test scores accounting for sociodemographics. Average and SD of 11 sleep measures over 7 days/nights were obtained. Rank regression, partial least-squares (PLS) regression, random forest, sleep dimension construct, and latent class analysis (LCA) were applied to evaluate associations between global T-scores and sleep measures. Results In 344 PWH (median age 57 years, 86% males), average sleep duration, efficiency, and wake after sleep onset were not associated with global T-scores according to rank regression (p = 0.51, p = 0.09, p = 0.16, respectively). In contrast, global T-scores were associated with average and SD of length of nocturnal awakenings, SD of maintenance efficiency, and average out-of-bed time when analyzed by PLS regression and random forest. No associations were found when using sleep dimensions or LCA. Overall, findings observed in PWH were similar to those seen in HIV-negative individuals (median age 61 years, 67% males). Conclusions Using multivariable analytical approaches, measures of sleep continuity, timing, and regularity were associated with cognitive performance in PWH, supporting the utility of newer methods of incorporating multiple standard and novel measures of sleep-wake patterns in the assessment of health and functioning.

Quality of life (QoL) is recognized as an essential end point in the disease management of chronic conditions such as HIV with calls to include good QoL as a ‘fourth 90’ in the 90-90-90 testing and treatment targets introduced by World Health Organization in 2016. Cognitive impairments impact a broad spectrum of experiences and are a common issue effecting people living with HIV (PLWH). Despite this, few studies have examined QoL in PLWH who also have a cognitive disorder. This study aimed to synthesize and describe what is known about QoL in those living with HIV-associated neurocognitive disorders (HAND). A scoping review of peer-reviewed literature was conducted to identify how QoL has been investigated and measured in PLWH with HAND, and how PLWH with HAND report and describe their QoL. We searched PsychInfo, Medline, Scopus, and Web of Science along with hand-searching reference lists from relevant studies found. Included studies were those published in English after 1st January 2003 which included PLWH with cognitive impairment not due to other pre-existing conditions. Fifteen articles met criteria for inclusion. Two studies measured QoL as a primary aim, with others including QoL assessment as part of a broader battery of outcomes. The MOS-HIV and SF-36 were the most commonly used measures of overall QoL, with findings generally suggestive of poorer overall QoL in PLWH with HAND, compared to PLWH without cognitive impairment. Studies which examined dimensions of QoL focused exclusively on functionality, level of independence, and psychological QoL domains. There is a considerable dearth of research examining QoL in PLWH with HAND. The initiatives which advocate for healthy aging and improved QoL in PLWH must be extended to include and understand the experiences those also living with cognitive impairment. Research is needed to understand the broad experiential impacts of living with these two complex, chronic conditions, to ensure interventions are meaningful to patients and potential benefits are not missed.

Background Self-reported sleep quality is poor in persons with human immunodeficiency virus (PWH), but prior studies commonly used nonspecific questionnaires, investigated only single sleep disorders, or lacked human immunodeficiency virus (HIV)-negative controls. We addressed these limitations in the Pharmacokinetics and Clinical Observations in People Over Fifty (POPPY) Sleep Substudy by assessing PWH and HIV-negative controls for insomnia, restless legs syndrome (RLS), and sleep apnea (SA). Methods Previously enrolled POPPY participants coenrolled in this substudy without regard to sleep symptoms. Participants completed validated sleep assessments including the Insomnia Severity Index questionnaire, International Restless Legs Syndrome Study Group questionnaire, and in-home, wrist-worn overnight oximetry. They also completed health-related quality of life questionnaires including 36-item Short Form (SF-36) and Patient-Reported Outcomes Measurement Information System (PROMIS) sleep questionnaires. Results We enrolled 357 PWH (246 >50 years of age; 111 between 18 and 50 years) and 126 HIV-negative controls >50 years of age. Among PWH, criteria were met by 21% for insomnia, 13% for RLS, and 6% for SA. Compared with HIV-negative controls, PWH had a higher risk of insomnia (adjusted odds ratio, 5.3; 95% confidence interval, 2.2–12.9) but not RLS or SA. Compared with PWH without insomnia, those with insomnia reported significantly worse scores on all SF-36 and PROMIS components; fewer than 30% reported previous diagnosis or treatment for insomnia. Conclusions Insomnia was more common in PWH, associated with worse health-related quality of life, and frequently undiagnosed. Further research should focus on the pathogenesis of insomnia in PWH and the development of effective screening and intervention strategies for this unique population.

IntroductionAs the prevalence of Long COVID increases, there is a critical need for a comprehensive assessment of disability. Our aims are to: (1) characterise disability experiences among people living with Long COVID in Canada, UK, USA and Ireland; and (2) develop a patient-reported outcome measure to assess the presence, severity and episodic nature of disability with Long COVID.Methods and analysisIn phase 1, we will conduct semistructured interviews with adults living with Long COVID to explore experiences of disability (dimensions, uncertainty, trajectories, influencing contextual factors) and establish an episodic disability (ED) framework in the context of Long COVID (n~10 each country). Using the conceptual framework, we will establish the Long COVID Episodic Disability Questionnaire (EDQ). In phase 2, we will examine the validity (construct, structural) and reliability (internal consistency, test–retest) of the EDQ for use in Long COVID. We will electronically administer the EDQ and four health status criterion measures with adults living with Long COVID, and readminister the EDQ 1 week later (n~170 each country). We will use Rasch analysis to refine the EDQ, and confirm structural and cross-cultural validity. We will calculate Cronbach’s alphas (internal consistency reliability), and intraclass correlation coefficients (test–retest reliability), and examine correlations for hypotheses theorising relationships between EDQ and criterion measure scores (construct validity). Using phase 2 data, we will characterise the profile of disability using structural equation modelling techniques to examine relationships between dimensions of disability and the influence of intrinsic and extrinsic contextual factors. This research involves an academic–clinical–community partnership building on foundational work in ED measurement, Long COVID and rehabilitation.Ethics and disseminationThis study was approved by the University of Toronto Research Ethics Board. Knowledge translation will occur with community collaborators in the form of presentations and publications in open access peer-reviewed journals and presentations.

Increasing access to more tolerable ARV treatments has vastly extended the expected lifespan of People with HIV (PWH), with some models predicting that in developed nations approximately two-thirds of PWH will be older than 50 years by 2030. Longer lifespans increase the risk of age-related neuropathologies, such as the deposition of amyloid beta plaques (Aβ42), regarded as an important prognostic marker of Alzheimer’s Disease (AD). Frequently first detected during mid-life, Aβ42 may predate the manifestation of neurocognitive symptoms associated with AD by 1-2 decades. \ud \ud The etiological significance of Aβ42 deposition in PWH is an active area of investigation. There is little clarity thus far in the clinical and research literature on whether the presence of Aβ42 in PWH leads to elevated risk of developing AD in those with and without HIV Associated Neurocognitive Disorders (HAND). Biological measures of neuropathology, such as CSF serum assays and brain tissue staining, have great potential in determining the extent to which Aβ42 deposition patterns in PWH are HAND-specific, and in linking these deposits to clinical outcomes. In this way, they might provide insight into otherwise seemingly paradoxical findings, such as the observation that neither age nor HIV clinical variables (including ARV status and duration of HIV infection) were able to explain the roughly 5 times greater incidence of mild cognitive impairment (MCI) over a period of 14 months in neurocognitively asymptomatic PWH compared to seronegative controls. \ud \ud In the study by Morgello and colleagues in this issue of AIDS, the authors examined hippocampal and frontal cortical tissue samples from a large cohort of 197 PWH and 63 HIV seronegative controls who donated brain tissue to the Manhattan HIV Brain Bank. Using this approach, they were able to quantify the association of HIV status and the presence of amyloid deposits in brain regions that are typically affected in AD. Despite the study being relatively well-powered, they were unable to identify between- 3 group differences in the occurrence of Aβ42 deposits. Rather, within the PWH cohort, duration of HIV infection, and, somewhat paradoxically, undetectable HIV viral load, emerged as significant predictors of the likelihood of detecting Aβ42.

Supplemental Digital Content is available in the text, Objective: To determine comorbidity indices in people with HIV (PWH) and lifestyle-similar HIV-negative controls. Design: Cross-sectional analysis of the Pharmacokinetic and clinical Observations in PeoPle over fiftY cohort study in the United Kingdom and Ireland. Methods: The Elixhauser Comorbidity Index (ECI), Charlson Comorbidity Index and the Comorbidity Burden Index were compared between older PWH and HIV-negative controls using the Mann–Whitney U test; the magnitude of the difference between groups was quantified using the r effect size. Results: The 699 PWH and 304 HIV-negative controls were predominantly male (87.5% vs. 64.0%), white (86.3% vs. 90.0%) and had median ages of 57 and 58 years, respectively. Among PWH, the median (interquartile range) CD4+ T-cell count was 624 (475, 811) cells/μl; 98.7% were on antiretroviral therapy. The median (interquartile range) ECI was 0 (0, 8) and 0 (−3, 1), Charlson Comorbidity Index was 2 (1, 5) and 1 (0, 1) and Comorbidity Burden Index 8.6 (2.2, 16.8) and 5.9 (0.6, 10.8), respectively. While all three indices were significantly higher in PWH than in controls (P

We assessed changes in functional connectivity by fMRI (functional magnetic resonance imaging) and cognitive measures in otherwise neurologically asymptomatic people with HIV (PWH) switching combination antiretroviral therapy (cART). In a prospective study (baseline and follow-up after at least 4 months), virologically suppressed PWH switched non-nuclease reverse-transcriptase inhibitors (NNRTI; tenofovir-DF/emtricitabine with efavirenz to rilpivirine) and integrase-strand-transfer inhibitors (INSTI; tenofovir-DF/emtricitabine with raltegravir to dolutegravir). PWH were assessed by resting-state fMRI and stop-signal reaction time (SSRT) task fMRI as well as with a cognitive battery (CogState™) at baseline and follow-up. Switching from efavirenz to rilpivirine (n = 10) was associated with increased functional connectivity in the dorsal attention network (DAN) and a reduction in SSRTs (p = 0.025) that positively correlated with the time previously on efavirenz (mean = 4.8 years, p = 0.02). Switching from raltegravir to dolutegravir (n = 12) was associated with increased connectivity in the left DAN and bilateral sensory-motor and associative visual networks. In the NNRTI study, significant improvements in the cognitive domains of executive function, working memory and speed of visual processing were observed, whereas no significant changes in cognitive function were observed in the INSTI study. Changes in fMRI are evident in PWH without perceived neuropsychiatric complaints switching cART. fMRI may be a useful tool in assisting to elucidate the underlying pathogenic mechanisms of cART-related neuropsychiatric effects.

Objectives\ud High rates of respiratory symptoms and chronic bronchitis (CB) are reported in people with HIV infection (PWH). We investigated the prevalence of respiratory symptoms and CB in PWH and HIV‐negative people in the Pharmacokinetic and clinical Observations in PeoPle over fiftY (POPPY) study.\ud \ud Methods\ud Assessment of respiratory symptoms and CB was undertaken using the modified form of the St. George’s Respiratory Questionnaire for chronic obstructive pulmonary disease (COPD). Univariate (χ2 tests, Mann–Whitney U tests and Spearman’s rank correlation) and multivariable (linear and logistic regression) analyses were performed to consider associations of respiratory symptoms with demographic, lifestyle and HIV‐related parameters, and with depressive symptoms and quality of life.\ud \ud Results\ud Among the 619 participants, respiratory Symptom scores were higher in older and younger PWH compared to older HIV‐negative people, with median (interquartile range) scores of 17.7 (6.2, 39.5), 17.5 (0.9, 30.0) and 9.0 (0.9, 17.5), respectively (P = 0.0001); these differences remained significant after confounder adjustment. Sixty‐three participants (10.2%) met the criteria for CB [44 (14.0%) older PWH, 14 (9.2%) younger PWH, and five (3.3%) older HIV‐negative people; P = 0.002], with these differences also remaining after adjustment for confounding variables, particularly smoking status [older vs. younger PWH: odds ratio (OR) 4.48 (95% confidence interval (CI) 1.64, 12.30); P = 0.004; older PWH vs. HIV‐negative people: OR 4.53 (95% CI 1.12, 18.28); P = 0.03]. Respiratory symptoms and CB were both associated with greater depressive symptom scores and poorer quality of life. No strong associations were reported between CB and immune function, HIV RNA or previous diagnosis of any AIDS event.\ud \ud Conclusions\ud Respiratory symptoms and CB are more common in PWH than in demographically and lifestyle‐similar HIV‐negative people and are associated with poorer mental health and quality of life.

As the number of people living with undiagnosed HIV infection in the UK declines, innovative ways to access those least engaged with services are needed. This study explores the attitudes of men who have sex with men (MSM) towards using HIV self-testing (HIVST) kits distributed via a vending machine in a sauna (a licenced sex-on-premise venue). Twenty-three MSM attending the sauna were recruited to take part in semi-structured qualitative interviews. The participants were overwhelmingly positive about the HIVST vending machine. They identified convenience and flexibility as major benefits to testing in this way. The sauna was felt to be an appropriate location for the intervention. Limitations identified included the potential to reduce screening for other sexually transmitted infections and the inappropriate use of HIVST kits as a tool for risk-assessment prior to condomless sex, with a poor understanding of the window period. The implications of receiving a positive result without immediate access to support were also a concern. HIVST vending machines are an acceptable, innovative way to encourage HIV testing. Providers need to ensure this intervention is supported by adequate information regarding the limitations of the test and how to access comprehensive services to avoid any unintended negative effects.

The use of digital vending machines (VMs) to delivery HIV self-testing (HIVST) could expand HIV testing in priority populations. We surveyed primarily Black African (BA) participants and other minority ethnicities, to identify acceptability, preferences, and concerns of using VMs for HIVST dispensing. A structured survey was developed with Black African and Caribbean, Latin American and other Minorities (BLAM) communities, and distributed between September 2018 and January 2019. Participants were recruited using mobile tablet surveys distributed by outreach volunteers, and online through BLAM communities’ websites, workshops, and language-specific messages on social media. Descriptive analyses were undertaken stratified by ethnic groups. One hundred and twenty-eight (67.0%) participants identified as BAs, 31 (16.2%) Black Caribbeans (BCs), 22 (11.5%) Latin Americans (LAs), and 10 (5.2%) other non-white ethnicities (ONWEs). Rates of willingness to use the HIVST were high in all groups except BCs (BAs 77.9%, BCs 53.6%, LAs 81.8%, ONWEs 80.0%). Most participants favoured healthcare-associated venues for VM placement, but there were differences in community venues favoured by different ethnic groups and concerns reported. HIVST is acceptable in many BLAM communities and increases understanding of the concerns and how to address them in the design of VMs for HIVST, to expand HIV testing in these priority communities.
