RESUMO

Electrical impedance spectroscopy (EIS) has been proposed as a promising noninvasive method to differentiate healthy thyroid from parathyroid tissues during thyroidectomy. However, previously reported similarities in the in vivo measured spectra of these tissues during a pilot study suggest that this separation may not be straightforward. We utilise computational modelling as a method to elucidate the distinguishing characteristics in the EIS signal and explore the features of the tissue that contribute to the observed electrical behaviour. Firstly, multiscale finite element models (or 'virtual tissue constructs') of thyroid and parathyroid tissues were developed and verified against in vivo tissue measurements. A global sensitivity analysis was performed to investigate the impact of physiological micro-, meso- and macroscale tissue morphological features of both tissue types on the computed macroscale EIS spectra and explore the separability of the two tissue types. Our results suggest that the presence of a surface fascia layer could obstruct tissue differentiation, but an analysis of the separability of simulated spectra without the surface fascia layer suggests that differentiation of the two tissue types should be possible if this layer is completely removed by the surgeon. Comprehensive in vivo measurements are required to fully determine the potential for EIS as a method in distinguishing between thyroid and parathyroid tissues.

RESUMO

BACKGROUND: Ageing populations globally have contributed to increasing numbers of people living with frailty, which has significant implications for use of health and care services and costs. The British Geriatrics Society defines frailty as "a distinctive health state related to the ageing process in which multiple body systems gradually lose their inbuilt reserves". This leads to an increased susceptibility to adverse outcomes, such as reduced physical function, poorer quality of life, hospital admissions, and mortality. Case management interventions delivered in community settings are led by a health or social care professional, supported by a multidisciplinary team, and focus on the planning, provision, and co-ordination of care to meet the needs of the individual. Case management is one model of integrated care that has gained traction with policymakers to improve outcomes for populations at high risk of decline in health and well-being. These populations include older people living with frailty, who commonly have complex healthcare and social care needs but can experience poorly co-ordinated care due to fragmented care systems. OBJECTIVES: To assess the effects of case management for integrated care of older people living with frailty compared with usual care. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, CINAHL, Health Systems Evidence, and PDQ Evidence and databases from inception to 23 September 2022. We also searched clinical registries and relevant grey literature databases, checked references of included trials and relevant systematic reviews, conducted citation searching of included trials, and contacted topic experts. SELECTION CRITERIA: We included randomised controlled trials (RCTs) that compared case management with standard care in community-dwelling people aged 65 years and older living with frailty. DATA COLLECTION AND ANALYSIS: We followed standard methodological procedures recommended by Cochrane and the Effective Practice and Organisation of Care Group. We used the GRADE approach to assess the certainty of the evidence. MAIN RESULTS: We included 20 trials (11,860 participants), all of which took place in high-income countries. Case management interventions in the included trials varied in terms of organisation, delivery, setting, and care providers involved. Most trials included a variety of healthcare and social care professionals, including nurse practitioners, allied healthcare professionals, social workers, geriatricians, physicians, psychologists, and clinical pharmacists. In nine trials, the case management intervention was delivered by nurses only. Follow-up ranged from three to 36 months. We judged most trials at unclear risk of selection and performance bias; this consideration, together with indirectness, justified downgrading the certainty of the evidence to low or moderate. Case management compared to standard care may result in little or no difference in the following outcomes. • Mortality at 12 months' follow-up (7.0% in the intervention group versus 7.5% in the control group; risk ratio (RR) 0.98, 95% confidence interval (CI) 0.84 to 1.15; I2 = 11%; 14 trials, 9924 participants; low-certainty evidence) • Change in place of residence to a nursing home at 12 months' follow-up (9.9% in the intervention group versus 13.4% in the control group; RR 0.73, 95% CI 0.53 to 1.01; I2 = 0%; 4 trials, 1108 participants; low-certainty evidence) • Quality of life at three to 24 months' follow-up (results not pooled; mean differences (MDs) ranged from -6.32 points (95% CI -11.04 to -1.59) to 6.1 points (95% CI -3.92 to 16.12) when reported; 11 trials, 9284 participants; low-certainty evidence) • Serious adverse effects at 12 to 24 months' follow-up (results not pooled; 2 trials, 592 participants; low-certainty evidence) • Change in physical function at three to 24 months' follow-up (results not pooled; MDs ranged from -0.12 points (95% CI -0.93 to 0.68) to 3.4 points (95% CI -2.35 to 9.15) when reported; 16 trials, 10,652 participants; low-certainty evidence) Case management compared to standard care probably results in little or no difference in the following outcomes. • Healthcare utilisation in terms of hospital admission at 12 months' follow-up (32.7% in the intervention group versus 36.0% in the control group; RR 0.91, 95% CI 0.79 to 1.05; I2 = 43%; 6 trials, 2424 participants; moderate-certainty evidence) • Change in costs at six to 36 months' follow-up (results not pooled; 14 trials, 8486 participants; moderate-certainty evidence), which usually included healthcare service costs, intervention costs, and other costs such as informal care. AUTHORS' CONCLUSIONS: We found uncertain evidence regarding whether case management for integrated care of older people with frailty in community settings, compared to standard care, improved patient and service outcomes or reduced costs. There is a need for further research to develop a clear taxonomy of intervention components, to determine the active ingredients that work in case management interventions, and identify how such interventions benefit some people and not others.

RESUMO

Solid tumour growth depends on a host of factors which affect the cell life cycle and extracellular matrix vascularization that leads to a favourable environment. The whole solid tumour can either grow or wither in response to the action of the immune system and therapeutics. A personalised mathematical model of such behaviour must consider both the intra- and inter-cellular dynamics and the mechanics of the solid tumour and its microenvironment. However, such wide range of spatial and temporal scales can hardly be modelled in a single model, and require the so-called multiscale models, defined as orchestrations of single-scale component models, connected by relation models that transform the data for one scale to another. While multiscale models are becoming common, there is a well-established engineering approach to the definition of the scale separation, e.g., how the spatiotemporal continuum is split in the various component models. In most studies scale separation is defined as natural, linked to anatomical concepts such as organ, tissue, or cell; but these do not provide reliable definition of scales: for examples skeletal organs can be as large as 500 mm (femur), or as small as 3 mm (stapes). Here we apply a recently proposed scale-separation approach based on the actual experimental and computational limitations to a patient-specific model of the growth of neuroblastoma. The resulting multiscale model can be properly informed with the available experimental data and solved in a reasonable timeframe with the available computational resources.

RESUMO

A multiscale modelling approach has been applied to the simulation of the electrical properties of oral tissue, for the purpose of informing an electrical impedance-based method of oral potential malignant disorder (OPMD) diagnosis. Finite element models of individual cell types, with geometry informed by histological analysis of human oral tissue (normal, hyperplastic and dysplastic), were generated and simulated to obtain electrical parameters. These were then used in a histology-informed tissue scale model, including the electrode geometry of the ZedScan tetrapolar impedance-measurement device. The simulations offer insight into the feasibility of distinguishing moderate dysplasia from severe dysplasia or healthy tissue. For some oral sites, simulated spectra agreed with real measurements previously collected using ZedScan. However, similarities between simulated spectra for dysplastic, keratinised and non-dysplastic but hyperkeratinised tissue suggest that significant keratinisation could cause some OPMD tissues to exhibit larger than expected impedance values. This could lead to misidentification of OPMD spectra as healthy. Sources of uncertainty within the models were identified and potential remedies proposed.

RESUMO

Urothelium is a transitional, stratified epithelium that lines the lower urinary tract, providing a tight barrier to urine whilst retaining the capacity to stretch and rapidly resolve damage. The role of glycerophospholipids in urothelial barrier function is largely unknown, despite their importance in membrane structural integrity, protein complex assembly, and the master regulatory role of PPARγ in urothelial differentiation. We performed lipidomic and transcriptomic characterisation of urothelial differentiation, revealing a metabolic switch signature from fatty acid synthesis to lipid remodelling, including 5-fold upregulation of LPCAT4. LPCAT4 knockdown urothelial cultures exhibited an impaired proliferation rate but developed elevated trans-epithelial electrical resistances upon differentiation, associated with a reduced and delayed capacity to restitute barrier function after wounding. Specific reduction in 18:1 PC fatty acyl chains upon knockdown was consistent with LPCAT4 specificity, but was unlikely to elicit broad barrier function changes. However, transcriptomic analysis of LPCAT4 knockdown supported an LPC-induced reduction in DAG availability, predicted to limit PKC activity, and TSPO abundance, predicted to limit endogenous ATP. These phenotypes were confirmed by PKC and TSPO inhibition. Together, these data suggest an integral role for lipid mediators in urothelial barrier function and highlight the strength of combined lipidomic and transcriptomic analyses for characterising tissue homeostasis.

RESUMO

This scoping review considers 11 studies that have focussed on the effect of teaching the mindfulness element of Dialectical Behaviour Therapy (DBT) on clinical outcomes. These articles utilized either mindfulness skills as embedded into the full DBT-Skills programme or a stand-alone mindfulness skills module (DBT-M), as treatment for clinical populations. The review of the research found that clinical application of mindfulness as taught in DBT leads to increases in self-reported mindfulness-especially non-judgemental awareness along with psychological measures that suggests an increase in mindfulness, for example, improved attention. The studies demonstrated that an increase in mindfulness had a positive effect on some clinical symptoms such as symptoms of Borderline Personality Disorder. Not all of the studies controlled for the effect of group, amount of practice or other elements of DBT therapy. The findings suggest that more needs to be done to establish the underlying mechanisms of change when being taught mindfulness in DBT.

RESUMO

OBJECTIVE: To develop a manualised psychological treatment for tinnitus that could enhance audiologist usual care, and to test feasibility of evaluating it in a randomised controlled trial. DESIGN: Feasibility trial, random allocation of patients to manualised treatment or treatment as usual, and mixed-methods evaluation. Study sample: Senior audiologists, and adults with chronic tinnitus. RESULTS: Recruitment reached 63% after 6 months (feasibility pre-defined as 65%). Only nine patients (47%) were retained for the duration of the trial. Patients reported that the treatment was acceptable and helped reassure them about their tinnitus. Audiologists reported mixed feelings about the kinds of techniques that are presented to them as 'psychologically informed'. Audiologists also reported lacking confidence because the training they had was brief, and stated that more formal supervision would have been helpful to check adherence to the treatment manual. CONCLUSIONS: The study indicate potential barriers to audiologist use of the manual, and that a clinical trial of the intervention is not yet feasible. However, positive indications from outcome measures suggest that further development work would be worthwhile. Refinements to the manual are indicated, and training and supervision arrangements to better support audiologists to use the intervention in the clinic are required. Trial Registration: ISRCTN13059163.

RESUMO

BACKGROUND: Managing hearing communication for residents living with hearing loss and dementia in long-term care settings is challenging. This paper explores how care can be effective in optimising hearing communication for residents living with dementia. We argue that the underlying notion of permission or authorisation allows care staff to do what they know will be effective in providing person-centred care that enhances hearing communication. The paper also indicates that this notion of permission can usefully be applied to other areas of care home practice. METHODS: To address hearing-related communication in care homes, we conducted a realist synthesis (RS). As a theory-driven approach to reviewing literature, it also uses expert opinion to understand complex health situations. Using RS, we developed a theory surrounding the management of hearing-related communication in care homes. Applying formal processes to the literature search and data extraction, the analysis uncovered relevant mechanisms and contexts to help confirm, refute or refine our understanding of how hearing communication could be improved. RESULTS: Forty-three papers were selected for the realist synthesis. The documents were analysed to construct five context-mechanism-outcome configurations (CMOCs). The CMOCs represent possible care interventions to optimise hearing-related communication in care homes for person living with dementia and hearing loss (PLWDHL). They include leadership promoting positive regard and empathy through person-centred care, communication training for staff, 'knowing the person' and relationship building for responsive awareness of residents' hearing needs, maintaining and monitoring hearing communication through care planning, and managing noise in the care home environment. CONCLUSIONS: Leadership that provides appropriate training and resources is likely to enhance knowledge and skills, leading to staff feeling able and equipped to respond to the hearing-related communication needs of PLWDHL. Collaboration with local hearing services is likely to raise awareness of hearing loss among care home staff. Importantly, care staff require a sense of permission from leadership, to work with knowledge and autonomy in the interest of residents living with dementia and hearing loss.

RESUMO

OBJECTIVE: To establish feasibility of initiating electrical stimulation treatment of wrist extensors and flexors in patients early after stroke to prevent muscle contractures and pain. DESIGN: Feasibility randomized controlled trial with economic evaluation. SETTING: A specialist stroke unit in Nottinghamshire. SUBJECTS: A total of 40 patients recruited within 72 hours post-stroke with arm hemiparesis. INTERVENTIONS: Participants were randomized to receive usual care or usual care and electrical stimulation to wrist flexors and extensors for 30 minutes, twice a day, five days a week for three months. Initial treatment was delivered by an occupational therapist or physiotherapist who trained participants to self-manage subsequent treatments. MEASURES: Measures of feasibility included recruitment and attrition rates, completion of treatment, and successful data collection. Outcome data on wrist range of motion, pain, arm function, independence, quality of life, and resource use were measured at 3-, 6-, and 12-months post-randomization. RESULTS: A total of 40 participants (of 215 potentially eligible) were recruited in 15 months (20 men; mean age: 72 (SD: 13.0)). Half the participants lacked mental capacity and were recruited by consultee consent. Attrition at three-month follow-up was 12.5% (death (n = 2), end-of-life care (n = 2), and unable to contact (n = 1)). Compliance varied (mean: 65 (SD: 53)) and ranged from 10 to 166 treatments per patient (target dosage was 120). Data for a valid economic analysis can be adequately collected. CONCLUSION: Early initiation of electrical stimulation was acceptable and feasible. Data collection methods used were feasible and acceptable to participants. A large definitive study is needed to determine if electrical stimulation is efficacious and cost effective.

RESUMO

Environmental data justice (EDJ) emerges from conversations between data justice and environmental justice while identifying the limits and tensions of these lenses. Through a reflexive process of querying our entanglement in non-innocent relations, this paper develops and engages EDJ by examining how it informs the work of the Environmental Data & Governance Initiative (EDGI), a distributed, consensus-based organization that formed in response to the 2016 US presidential election. Through grassroots archiving of data sets, monitoring federal environmental and energy agency websites, and writing rapid-response reports about how federal agencies are being undermined, EDGI mobilises EDJ to challenge the 'extractive logic' of current federal environmental policy and data infrastructures. 'Extractive logic' disconnects data from provenance, privileges the matrix of domination, and whitewashes data to generate uncertainty. We use the dynamic EDJ framework to reflect on EDGI's public comment advising against the US Environmental Protection Agency's proposed rule for Transparent Science. Through EDJ, EDGI aspires to create new environmental data infrastructures and practices that are participatory and embody equitable, transparent data care.

RESUMO

OBJECTIVES: The aim of this study was to determine which components of psychological therapies are most important and appropriate to inform audiologists' usual care for people with tinnitus. DESIGN: A 39-member panel of patients, audiologists, hearing therapists, and psychologists completed a three-round Delphi survey to reach consensus on essential components of audiologist-delivered psychologically informed care for tinnitus. RESULTS: Consensus (≥80% agreement) was reached on including 76 of 160 components. No components reached consensus for exclusion. The components reaching consensus were predominantly common therapeutic skills such as Socratic questioning and active listening, rather than specific techniques, for example, graded exposure therapy or cognitive restructuring. Consensus on educational components to include largely concerned psychological models of tinnitus rather than neurophysiological information. CONCLUSIONS: The results of this Delphi survey provide a tool to develop audiologists' usual tinnitus care using components that both patients and clinicians agree are important and appropriate to be delivered by an audiologist for adults with tinnitus-related distress. Research is now necessary to test the added effects of these components when delivered by audiologists.

RESUMO

BACKGROUND: Tinnitus is associated with depression and anxiety disorders, severely and adversely affecting the quality of life and functional health status for some people. With the dearth of clinical psychologists embedded in audiology services and the cessation of training for hearing therapists in the UK, it is left to audiologists to meet the psychological needs of many patients with tinnitus. However, there is no universally standardized training or manualized intervention specifically for audiologists across the whole UK public healthcare system and similar systems elsewhere across the world. OBJECTIVES: The primary aim of this scoping review was to catalog the components of psychological therapies for people with tinnitus, which have been used or tested by psychologists, so that they might inform the development of a standardized audiologist-delivered psychological intervention. Secondary aims of this article were to identify the types of psychological therapy for people with tinnitus, who were reported but not tested in any clinical trial, as well as the job roles of clinicians who delivered psychological therapy for people with tinnitus in the literature. DESIGN: The authors searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; Cochrane Central Register of Controlled Trials; PubMed; EMBASE; CINAHL; LILACS; KoreaMed; IndMed; PakMediNet; CAB Abstracts; Web of Science; BIOSIS Previews; ISRCTN; ClinicalTrials.gov; IC-TRP; and Google Scholar. In addition, the authors searched the gray literature including conference abstracts, dissertations, and editorials. No records were excluded on the basis of controls used, outcomes reached, timing, setting, or study design (except for reviews-of the search results. Records were included in which a psychological therapy intervention was reported to address adults (≤18 years) tinnitus-related distress. No restrictive criteria were placed upon the term tinnitus. Records were excluded in which the intervention included biofeedback, habituation, hypnosis, or relaxation as necessary parts of the treatment. RESULTS: A total of 5043 records were retrieved of which 64 were retained. Twenty-five themes of components that have been included within a psychological therapy were identified, including tinnitus education, psychoeducation, evaluation treatment rationale, treatment planning, problem-solving behavioral intervention, thought identification, thought challenging, worry time, emotions, social comparison, interpersonal skills, self-concept, lifestyle advice, acceptance and defusion, mindfulness, attention, relaxation, sleep, sound enrichment, comorbidity, treatment reflection, relapse prevention, and common therapeutic skills. The most frequently reported psychological therapies were cognitive behavioral therapy, tinnitus education, and internet-delivered cognitive behavioral therapy. No records reported that an audiologist delivered any of these psychological therapies in the context of an empirical trial in which their role was clearly delineated from that of other clinicians. CONCLUSIONS: Scoping review methodology does not attempt to appraise the quality of evidence or synthesize the included records. Further research should therefore determine the relative importance of these different components of psychological therapies from the perspective of the patient and the clinician.

RESUMO

BACKGROUND: There is limited evidence of medication adherence related to progression of chronic kidney disease (CKD) worldwide. The aim of this study was to determine associations between medication adherence and the progression of CKD in outpatients with CKD. METHODS: This cohort study recruited 339 Thai patients with stages 3-5 CKD. Patients with a glomerular disease or receiving renal replacement therapy before recruitment were excluded. 295 were followed up regarding their serum creatinine, blood pressure, glycated hemoglobin, and low-density lipoprotein cholesterol over 12 months. Medication adherence was measured at baseline using the Thai version of the 8-Item Morisky Medication Adherence Scale®. The primary outcome was the progression of CKD. The progression of CKD was defined as either a decline in estimated glomerular filtration rate of at least 3 ml/min/1.73 m2/year or initiation of renal replacement therapy. Univariate and multivariate analyses were performed using Chi-squared tests and multiple logistic regressions. RESULTS: Twenty-one percent had poor adherence. Younger patients were more likely to have poor adherence (adjusted OR 2.81, 95 % CI 1.45-5.43). Anti-hypertensive agents were the most frequently reported as not being taken (52 %). Patients with poor adherence were associated with the progression of CKD (adjusted OR 1.96, 95 % CI 1.02-3.76). Those with poor adherence were less likely to control their blood pressure, than moderate-to-high adherence group (p < 0.01). CONCLUSION: The findings suggest that CKD patients with poor medication adherence are more likely to have progression of CKD. Health care providers should acknowledge these findings and provide effective strategies to deal with this issue.

RESUMO

Background Getting research funded is extremely difficult, with research councils rejecting more than 70% of grant applications ( Else 2014 ). It is even more difficult if you are a junior researcher who doesn't have a track record of being awarded grant money or leading a research project. Crowdfunding may offer a solution. It is a method of raising funds from members of the public online and can offer an alternative to the more formal methods of research funding. Aim To outline how this model works and provide tips on designing a campaign. Discussion The authors provide an overview of the literature regarding this model, as well as a set of resources for future reference when designing a campaign. Conclusion Crowdfunding can provide small amounts of money for your first project. Implications for practice It is expected that clinicians practice evidence based medicine, and research in health environments is commonplace. Crowdfunding can offer you support in becoming more engaged in research.

RESUMO

Numerous disease-causing parasites must invade host cells in order to prosper. Collectively, such pathogens are responsible for a staggering amount of human sickness and death throughout the world. Leishmaniasis, Chagas disease, toxoplasmosis, and malaria are neglected diseases and therefore are linked to socio-economical and geographical factors, affecting well-over half the world's population. Such obligate intracellular parasites have co-evolved with humans to establish a complexity of specific molecular parasite-host cell interactions, forming the basis of the parasite's cellular tropism. They make use of such interactions to invade host cells as a means to migrate through various tissues, to evade the host immune system, and to undergo intracellular replication. These cellular migration and invasion events are absolutely essential for the completion of the lifecycles of these parasites and lead to their for disease pathogenesis. This review is an overview of the molecular mechanisms of protozoan parasite invasion of host cells and discussion of therapeutic strategies, which could be developed by targeting these invasion pathways. Specifically, we focus on four species of protozoan parasites Leishmania, Trypanosoma cruzi, Plasmodium, and Toxoplasma, which are responsible for significant morbidity and mortality.

RESUMO

AIM: To determine associations between herbal and dietary supplement (HDS) use and the progression of chronic kidney disease (CKD), and associations of HDS with uncontrolled hyperphosphataemia in patients with CKD. METHOD: The cohort study recruited 406 Thai outpatients with stage 3-5 CKD from two kidney clinics of which 357 were followed up over 12 months. Patients receiving renal replacement therapy prior to recruitment were excluded. Participants were interviewed regarding their HDS use, dietary intake and conventional medication adherence using a questionnaire. The primary outcome was a composite of a decline of at least 5 mL/min per 1.73 m2 per year of estimated glomerular filtration rate and end stage renal disease. Serum creatinine, serum levels of potassium and phosphate were extracted from their medical notes over the 12 months. χ2 tests and multiple logistic regression analyses were performed to ascertain any associations. RESULTS: Despite no association between HDS and the progression of CKD over a one-year period (adjusted odds ratio (OR) 1.16, 95% confidence interval (CI) 0.66-2.03), two patients had acute kidney injury, which may be related to an unknown Chinese herbal medicine, or river spiderwort combined with diclofenac reported in the medical notes. The use of HDS was associated with uncontrolled hyperphosphataemia (adjusted OR 3.53, 95%CI 1.20-10.43). CONCLUSIONS: The findings suggest that HDS are likely to be related to acute kidney injury rather than the progression of CKD in Thai patients with CKD. The products were associated with uncontrolled hyperphosphataemia. Patients who have CKD and use HDS should be closely monitored regarding their kidney function and electrolytes.

RESUMO

BACKGROUND: Increasingly, research grant awarding bodies are regarding involvement at all stages of research, including prior to funding, as good practice. However, it is unclear how researchers should pay for this. Therefore, a pre-funding bursary scheme was designed. Up to £500 could be requested for involvement to develop a grant application for which user involvement is a key requisite for the funding body concerned. As the bursary scheme had run for 2 years, an evaluation was conducted to ascertain whether the scheme was effective for incorporating early involvement and in developing the grant proposal. RESULTS: Twelve applications were made of which all were funded. The mean amount requested was £432.91; with the mean amount awarded £308.72. The involvement activities conducted all used qualitative methodology. Feedback regarding the bursaries was positive: enabling refinement of the research question and design; developing dialogue between the service users and the researchers; and helping with team building, with service users sometimes becoming co-applicants or members of the steering groups. The bursaries provided a learning opportunity ­ about involvement for the researchers and about research for the service users. The ultimate aim of the scheme was to enhance the research grant. Regarding this, the involvement paid for by the bursary meant that applicants could complete the involvement sections with in-depth information and clarity. CONCLUSION: For a relatively small financial outlay, appropriate involvement was made possible at an important part of the research process which is usually neglected due to lack of funding. Recommendations for implementation made.

RESUMO

BACKGROUND: Vitiligo is a chronic depigmenting skin disorder which affects around 0.5-1% of the world's population. The outcome measures used most commonly in trials to judge treatment success focus on repigmentation. Patient-reported outcome measures of treatment success are rarely used, although recommendations have been made for their inclusion in vitiligo trials. This study aimed to evaluate the face validity of a new patient-reported outcome measure of treatment response, for use in future trials and clinical practice. METHOD: An online survey to gather initial views on what constitutes treatment success for people with vitiligo or their parents/carers, followed by online discussion groups with patients to reach consensus on what constitutes treatment success for individuals with vitiligo, and how this can be assessed in the context of trials. Participants were recruited from an existing database of vitiligo patients and through posts on the social network sites Facebook and Twitter. RESULTS: A total of 202 survey responses were received, of which 37 were excluded and 165 analysed. Three main themes emerged as important in assessing treatment response: a) the match between vitiligo and normal skin (how well it blends in); b) how noticeable the vitiligo is and c) a reduction in the size of the white patches. The majority of respondents said they would consider 80% or more repigmentation to be a worthwhile treatment response after 9 months of treatment. Three online discussion groups involving 12 participants led to consensus that treatment success is best measured by asking patients how noticeable their vitiligo is after treatment. This was judged to be best answered using a 5-point Likert scale, on which a score of 4 or 5 represents treatment success. CONCLUSIONS: This study represents the first step in developing a patient reported measure of treatment success in vitiligo trials. Further work is now needed to assess its construct validity and responsiveness to change.

RESUMO

BACKGROUND: Despite a high prevalence of herbal and dietary supplement use (HDS) in pre-dialysis patients, the reasons are unknown as to why they decide to use HDS. Objectives of the cross-sectional and qualitative studies were to determine reasons for the use and non-use of HDS in Thai patients with chronic kidney disease (CKD). METHODS: This prospective study recruited 421 patients with stage 3-5 CKD from two kidney clinics in Thailand, and 357 were followed up regarding their HDS use over 12 months. Patients receiving renal replacement therapy at baseline were excluded. Participants were interviewed at baseline and in the twelfth month regarding their HDS use, and reasons for their use or non-use of HDS. Among HDS users, 16 patients were enrolled in a qualitative study and were interviewed using eight-open ended questions about reasons for HDS use. Descriptive and thematic analyses were performed. RESULTS: Thirty-four percent of patients with CKD consistently used HDS over the 12 months and 17% of all patients intermittently took them during the follow-up period. At baseline, family or friends' recommendation was the most common reason for HDS use (35%), followed by having a perception of benefits from using HDS (24%). During the follow-up period, perceived benefits of HDS was a frequently reported reason for either continuing with HDS use (85%) or starting to use HDS (65%). Negative experience from using HDS influenced patients to stop using them (19%). Although the main reason for non-use of HDS was trust in a doctor or effectiveness of conventional medicine (32%), doubt about the benefits from HDS or concerns about negative effects were frequently reported reasons for non-use (23%). Doctor's recommendations to avoid using HDS were the main influence for non-users (19%) and for those who had stopped using HDS (23%). The media and patients' social network had an impact on HDS use. CONCLUSIONS: Patients who perceived benefits from HDS use were more likely to use HDS, whilst non-users had negative attitudes towards HDS. Health professionals therefore should educate patients and their relatives about the risks and benefits from using HDS.

RESUMO

BACKGROUND: Multidomain interventions in older adults offer the best opportunity to prevent, delay or reverse existing symptoms in the earlier stages of frailty and improve independence but can be costly, and difficult to deliver at scale. However, digital health interventions enable personalised care and empowerment through self-management of long-term conditions, used at any time and when combined with health coaching offer the potential to enhance well-being and facilitate the achievement of health-related goals. We aim to evaluate the feasibility and acceptability of a digital health platform for long-term disease management combined with health coaching for people living with mild-moderate frailty, targeting self-identified goals-activity, nutrition, mood, enhancing social engagement and well-being. METHODS AND ANALYSIS: This is a non-randomised feasibility, single-group, pretest/post-test study, using qualitative and quantitative methods. The digital health coaching intervention (DIALOR-DIgitAL cOaching for fRailty) has been developed for implementation to older adults, aged 65 years or older with mild to moderate frailty and diagnosis of one or more long-term health conditions in the community. Participants will receive 12 weeks of health coaching and have access to a mobile health platform for 6 months. The primary outcome measure is the acceptability and feasibility of DIALOR along with a range of secondary outcome measures (including frailty, functioning measures, quality of life, social engagement, diet quality and self-reported indicators) collected at baseline and at 6 months. The findings will inform whether a wider effectiveness trial is feasible and if so, how it should be designed. ETHICS AND DISSEMINATION: Ethical approval has been granted by the Southeast Scotland Research Ethics Committee 02 (reference: 22/SS/0064). Research findings will be disseminated in a range of different ways to engage different audiences, including publishing in open-access peer-reviewed journals, conference presentations, social media, dissemination workshop with patients, carers, and healthcare professionals and on institution websites.
