RESUMO

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

RESUMO

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

RESUMO

BACKGROUND: Critical illness is a traumatic experience, often resulting in post-intensive care syndrome, affecting people's physical, psychological, emotional, and social well-being. The early recovery period is associated with increased risk, negatively impacting longer-term outcomes. AIMS: The aims of this study were to understand the recovery and rehabilitation needs of people who survive a COVID-19 critical illness. STUDY DESIGN: An exploratory descriptive qualitative interview study with 20 survivors of COVID-19 critical illness from two community-based healthcare settings in London, England. Data collection took place September 2020-April 2021, at least 1 month after hospital discharge by telephone or virtual platform. Data were subjected to inductive thematic analysis and mapped deductively to the three core concepts of self-determination theory: autonomy, competence and relatedness. RESULTS: Three key themes emerged: traumatic experience, human connection and navigating a complex system. Participants described how societal restrictions, fear and communication problems caused by the pandemic added to their trauma and the challenge of recovery. The importance of positive human connections, timely information and support to navigate the system was emphasized. CONCLUSIONS: Whilst findings to some extent mirror those of other qualitative pre-pandemic studies, our findings highlight how the uncertainty and instability caused by the pandemic add to the challenge of recovery affecting all core concepts of self-determination (autonomy, competence, relatedness). RELEVANCE TO CLINICAL PRACTICE: Understanding survivors' perspectives of rehabilitation needs following COVID-19 critical illness is vital to delivery of safe, high-quality care. To optimize chances of effective recovery, survivors desire a specialist, co-ordinated and personalized recovery pathway, which reflects humanized care. This should be considered when planning future service provisions.

RESUMO

We developed a chronic obstructive pulmonary disease (COPD) patient-reported experience measure (PREM-C9). 174 patients with COPD (86 [49%] with a confirmed diagnosis and 88 [51%] with a self-reported diagnosis of COPD) completed a 38-item list, COPD Assessment Test (CAT) and Hospital Anxiety and Depression Scale (HADS). Hierarchical and Rasch analysis produced a 9-item list (PREM-C9). It demonstrated fit to the Rasch model (χ² p=0.33) and correlated moderately with CAT (r=0.42), HAD-anxiety (r=0.30) and HAD-depression (r=0.41) (p<0.05). A substudy confirmed its ability to detect change prepulmonary and postpulmonary rehabilitation. The PREM-C9 is a simple, valid measure of experience of patients living with COPD, validated in this study population with mild to very severe disease; it may be a useful measure in research and clinical audits.

RESUMO

BACKGROUND: Lesbian, gay, bisexual and/or trans (LGBT) people have higher risk of certain life-limiting illnesses and unmet needs in advanced illness and bereavement. ACCESSCare is the first national study to examine in depth the experiences of LGBT people facing advanced illness. AIM: To explore health-care experiences of LGBT people facing advanced illness to elicit views regarding sharing identity (sexual orientation/gender history), accessing services, discrimination/exclusion and best-practice examples. DESIGN: Semi-structured in-depth qualitative interviews analysed using thematic analysis. SETTING/PARTICIPANTS: In total, 40 LGBT people from across the United Kingdom facing advanced illness: cancer ( n = 21), non-cancer ( n = 16) and both a cancer and a non-cancer conditions ( n = 3). RESULTS: In total, five main themes emerged: (1) person-centred care needs that may require additional/different consideration for LGBT people (including different social support structures and additional legal concerns), (2) service level or interactional (created in the consultation) barriers/stressors (including heteronormative assumptions and homophobic/transphobic behaviours), (3) invisible barriers/stressors (including the historical context of pathology/criminalisation, fears and experiences of discrimination) and (4) service level or interactional facilitators (including acknowledging and including partners in critical discussions). These all shape (5) individuals' preferences for disclosing identity. Prior experiences of discrimination or violence, in response to disclosure, were carried into future care interactions and heightened with the frailty of advanced illness. CONCLUSION: Despite recent legislative change, experiences of discrimination and exclusion in health care persist for LGBT people. Ten recommendations, for health-care professionals and services/institutions, are made from the data. These are simple, low cost and offer potential gains in access to, and outcomes of, care for LGBT people.

RESUMO

The prevalence and incidence of chronic obstructive pulmonary disease in the UK and worldwide is continuing to grow. Surveys are the most common method of collecting information about patients' views, health outcomes and experiences of healthcare. COPD-specific patient-reported outcome measures and quality of life measures exist but there is no COPD-specific patient-reported experience measure; this article describes the stages of developing one.

RESUMO

BACKGROUND: The PROUD trial, a HIV prevention trial in men who have sex with men and trans women, set out to involve community representatives and trial participants in several ways. PROUD also aimed to evaluate participant involvement, to learn lessons and make recommendations for future clinical trials. METHODS: Two structured surveys, one of participant and community representatives involved in the PROUD study, and the other of researchers from the PROUD team, were carried out in 2017. The results from the surveys were reviewed quantitatively and qualitatively, and themes emerging from the data identified and synthesised. RESULTS: Survey invitations were sent to 88 involved participants, 11 community representatives and 10 researchers. The overall response rate was 55% (60/109). Overall, participants were younger than community representatives, and the majority were from Greater London. As expected, participants were predominantly involved in participant involvement meetings and community representatives in management committees.Participants and community representatives cited different motivations for getting involved in PROUD. Overall, participants were positive about their involvement; only two participants rated their experience unfavourably. Community representatives were also broadly positive. Most participants and all community representatives felt their involvement made a difference to the trial, themselves and / or the organisations they represented. However, some participant answers reflected the impact of participation in the trial rather than involvement in PPI activities.Researchers felt that PPI had positive impact across the entire trial cycle. Half felt they would have liked there to have been more PPI activity in PROUD. Researchers noted some challenges and recommendations for the future, including need for adequate funding, more engagement in PPI by all researchers, the need for PPI expertise to facilitate involvement activities and training and mentoring in PPI. CONCLUSIONS: Involving clinical trial participants and wider community representatives as active partners in PPI is feasible and valuable in trials. Researchers are encouraged to consider and appropriately resource participant involvement and prospectively evaluate all PPI within their trials.

RESUMO

Respiratory nurses make a significant contribution to the delivery of respiratory healthcare, but there is a dearth of nurse-led, practice-focused, published research. Using a modified three-round Delphi, this study sought to identify research priorities for respiratory nursing to inform a national research strategy. Study information and the survey link were sent electronically to members of UK professional respiratory organisations. Round 1 had 78 items across 16 topics, informed by a systematic literature review. Respondents suggested additional items which were content analysed to inform Round 2. Respondents rated all items and ranked the topics in all rounds. To ensure rigour, rounds had an explicit focus with pre-determined criteria for consensus (70%). In total, 363 responses were received across Rounds 1, 2 and 3 (n=183, 95 and 85, respectively). The top five research priorities were: 1) "Patient understanding of asthma control"; 2) "The clinical and cost-effectiveness of respiratory nurse interventions"; 3) "The impact of nurse-led clinics on patient care"; 4) "Inhaler technique"; and 5) two topics jointly scored: "Prevention of exacerbations" and "Symptom management". With potential international significance, this is the first UK study to identify research priorities for respiratory nursing, providing direction for those planning or undertaking research.

RESUMO

The study aimed to explore patients' experience of living with chronic obstructive pulmonary disease and their perspective of their community healthcare for chronic obstructive pulmonary disease to extract affective responses in order to develop potential items for a patient-reported experience measure for chronic obstructive pulmonary disease. Qualitative face-face interviews were conducted, in the community, with 64 patients with chronic obstructive pulmonary disease recruited from General Practices and Breathe-Easy community groups in the Outer North East, East and City areas of London and Essex, UK. A two phase analysis of the qualitative data was conducted to identify themes arising from patients' description of living with chronic obstructive pulmonary disease and their perceptions of their community healthcare and subsequently the affective responses underlying the themes raised by patients, which gave emotional colour to the themes, bringing the thematic analysis closer to the subjective patient experience. Five themes were identified from the interview data: 'Journey to diagnosis'; 'Smoking'; 'Usual care'; 'My everyday life'; and 'Exacerbations'. Twenty-one affective responses were identified and categorised as either 'negative', 'positive' or 'bivalent'. 'Frustration', a negative affective response was prevalent in four themes. 'Gratitude', 'hope' and 'happiness/enjoyment' were among the more positive responses more prevalent across several themes. By conducting a novel two-way analysis (thematic and affective) it was possible to identify themes and affective responses that were aligned to those themes. This enabled the development of 38 chronic obstructive pulmonary disease-specific experience items to take forward for further testing including item reduction and validity and reliability in the next stage of the patient-reported experience measure development. CHRONIC LUNG DISEASE: GIVING IMPORTANCE TO PATIENTS' EMOTIONS: An exploration of patient perceptions of living with chronic lung disease will help develop a new patient reported experience scale. Healthcare services are aiming to provide effective patient-centered care for those with chronic obstructive pulmonary disease (COPD). Such care strategies require structured, validated patient feedback scales to facilitate accurate communication between patients, carers and healthcare professionals. Susan Walker at Anglia Ruskin University in Chelmsford, UK, and co-workers analyzed qualitative data from interviews with 64 COPD patients in London and Essex regarding their emotions and perceptions of living with COPD, with the aim of creating a patient reported experience measure, or PREM. Initial results identified five themes-including 'journey to diagnosis' and 'everyday life'-and twenty-one affective responses, ranging from negative to positive. The team will take these results forward for further validation.

RESUMO

Exacerbations of COPD carry a huge burden of morbidity and a significant economic impact. It has been shown that home care may be useful for exacerbations of COPD. This article presents a review of an integrated COPD service in east London. Hospital Episode Statistics, Public Health Mortality Files and clinical data were used to analyze differences in health care usage and COPD patient outcomes, including COPD assessment test (CAT) scores for a subsample, before and after the introduction of the integrated service. There was a significant (30%) reduction in the number of hospital bed days for COPD patients (P<0.05), alongside a significant increase in patients with only a short stay (0-1 days) in hospital (P<0.0001). There was a significant increase in the number of patients dying outside of hospital (a proxy for quality of end-of-life care) following introduction of the service (P=0.00015). Patients also reported a clinically significant improvement in CAT scores. A locally developed economic model shows that the economic benefits of the service (via impact on place of death and reduction in length of hospital stay) were almost equal to the cost of the service. The increase in proportion of short-stay admissions and the reduction in bed days suggest an impact of the service on early supported discharge and that this along with an improvement in patient clinical outcomes and in quality of end-of-life care shows that an exemplar integrated COPD service can provide benefits that equate to a nearly cost-neutral service.

RESUMO

Improvements in biomedical technologies, combined with changing social attitudes to sexual minorities, provide new opportunities for HIV prevention among gay and other men who have sex with men (GMSM). The potential of these new biomedical technologies (biotechnologies) to reduce HIV transmission and the impact of HIV among GMSM will depend, in part, on the degree to which they challenge prejudicial attitudes, practices and stigma directed against gay men and people living with HIV (PLHIV). At the structural level, stigma regarding gay men and HIV can influence the scale-up of new biotechnologies and negatively affect GMSM's access to and use of these technologies. At the personal level, stigma can affect individual gay men's sense of value and confidence as they negotiate serodiscordant relationships or access services. This paper argues that maximising the benefits of new biomedical technologies depends on reducing stigma directed at sexual minorities and people living with HIV and promoting positive social changes towards and within GMSM communities. HIV research, policy and programs will need to invest in: (1) responding to structural and institutional stigma; (2) health promotion and health services that recognise and work to address the impact of stigma on GMSM's incorporation of new HIV prevention biotechnologies; (3) enhanced mobilisation and participation of GMSM and PLHIV in new approaches to HIV prevention; and (4) expanded approaches to research and evaluation in stigma reduction and its relationship with HIV prevention. The HIV response must become bolder in resourcing, designing and evaluating programs that interact with and influence stigma at multiple levels, including structural-level stigma.

RESUMO

BACKGROUND: At present, there is not a widely accepted consensus view regarding the phylogenetic structure of kingdom Fungi although two major phyla, Ascomycota and Basidiomycota, are clearly delineated. Regarding the lower fungi, Zygomycota and Chytridiomycota, a variety of proposals have been advanced. Microsporidia may or may not be fungi; the Glomales (vesicular-arbuscular mycorrhizal fungi) may or may not constitute a fifth fungal phylum, and the loss of the flagellum may have occurred either once or multiple times during fungal evolution. All of these issues are capable of being resolved by a molecular phylogenetic analysis which achieves strong statistical support for major branches. To date, no fungal phylogeny based upon molecular characters has satisfied this criterion. RESULTS: Using the translated amino acid sequences of the RPB1 and RPB2 genes, we have inferred a fungal phylogeny that consists largely of well-supported monophyletic phyla. Our major results, each with significant statistical support, are: (1) Microsporidia are sister to kingdom Fungi and are not members of Zygomycota; that is, Microsporidia and fungi originated from a common ancestor. (2) Chytridiomycota, the only fungal phylum having a developmental stage with a flagellum, is paraphyletic and is the basal lineage. (3) Zygomycota is monophyletic based upon sampling of Trichomycetes, Zygomycetes, and Glomales. (4) Zygomycota, Basidiomycota, and Ascomycota form a monophyletic group separate from Chytridiomycota. (5) Basidiomycota and Ascomycota are monophyletic sister groups. CONCLUSION: In general, this paper highlights the evolutionary position and significance of the lower fungi (Zygomycota and Chytridiomycota). Our results suggest that loss of the flagellum happened only once during early stages of fungal evolution; consequently, the majority of fungi, unlike plants and animals, are nonflagellated. The phylogeny we infer from gene sequences is the first one that is congruent with the widely accepted morphology-based classification of Fungi. We find that, contrary to what has been published elsewhere, the four morphologically defined phyla (Ascomycota, Basidiomycota, Zygomycota and Chytridiomycota) do not overlap with one another. Microsporidia are not included within kingdom Fungi; rather they are a sister-group to the Fungi. Our study demonstrates the applicability of protein sequences from large, slowly-evolving genes to the derivation of well-resolved and highly supported phylogenies across long evolutionary distances.

RESUMO

Chronic obstructive pulmonary disease (COPD) is a long-term lung disease characterised by breathlessness, cough and sputum production. Progressively worsening breathlessness for the patient with COPD limits everyday activity, reduces quality of life and increases the risk of premature death. Beyond reducing symptoms and the rate and severity of exacerbations, the aim of treatment is to increase exercise capacity and improve overall health and wellbeing. Nurses have an important role in ensuring advance care planning is implemented for every patient. This article describes the diagnosis, assessment and management of COPD, and includes practical points for patient care.

RESUMO

RPB1 and RPB2, which encode the largest and second largest subunits of RNA polymerase II, respectively, are essential single copy genes in fungi, animals and most plants. Two paralogs of the RPB2 gene have been found in some groups of angioperms [Oxelman, B., Yoshikawa, N., McConaughy, B.L., Luo, J., Denton, A.L., Hall, B.D., 2004. RPB2 gene phylogeny in flowering plants, with particular emphasis on asterids. Mol. Phylogenet. Evol. 32, 462-479]. Here, we report the results of experiments designed to identify the evolutionary origin of the RPB2 duplicate copies. Through careful sampling and phylogenetic analysis, we were able to construct the RPB2 gene tree in angiosperms and infer the phylogenetic positions of the gene duplication and gene loss events that occurred. Our study shows that an RPB2 gene duplication occurred early in core eudicot evolution, at or near the time of the Buxaceae/Trochodendraceae divergence. Subsequently, multiple gene duplication and paralog sorting events happened independently in different core eudicot taxa. Differential expression of the two RPB2 gene paralogs may explain the preservation of both paralogs in the asterids. One gene (RPB2-i) accounts for most of the RPB2 mRNA made in the flower organs while the other gene (RPB2-d) is predominantly used in the vegetative tissues. We also found two paralogs of the RPB1 gene in some core eudicot species. The RPB1 gene duplication occurred before core eudicot divergence, around the time of RPB2 gene duplication. Several independent RPB1 paralog sorting events happened in different core eudicot taxa; their occurrence was independent of the RPB2 paralog sorting events. Our results suggest that a polyploidization event happened at or near the time of the Buxaceae/Trochodendraceae divergence. We propose that this polyploidization and the partial diploidization processes thereafter may have been the driving force of core eudicot radiation.
