The liminal space of first-episode psychosis and its treatment: A qualitative study exploring the experience of young people participating in an antipsychotic dose reduction randomized controlled trial.

OBJECTIVE: The current guidelines recommend continuation of antipsychotic medication for a minimum of at least 1 year following a first episode of psychosis (FEP). There have been several trials investigating whether early dose reduction or cessation leads to improved functional outcomes. The aim of this study was to explore the experience of consenting to and participating in a randomized controlled trial (RCT) of antipsychotic medication cessation. METHOD: Five participants in the Reduce trial-an RCT evaluating early antipsychotic medication dose reduction/cessation following FEP-aged 22-24 years completed a semistructured qualitative interview following the RCT. Interpretive phenomenological analysis was undertaken to understand the key themes. RESULTS: A superordinate theme was derived from interviews: the Liminal Space of FEP and treatment. Themes within the Liminal Space included: rejection versus identification with psychosis, medication as symbolic of illness versus wellness, embodiment of wellness and illness with medication, medication as symbolic of independence versus dependence, discovery of independence when autonomously choosing medication, the Reduce trial offered safety to navigate the liminal space, and self-exploration versus altruism. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: The experience and treatment of FEP involves young people feeling torn between multiple, competing perspectives, demands, and priorities. Participation in an RCT exploring dose reduction provided additional supports contributing to the perception of greater safety to navigate their own experiences of treatment that was appropriate for them. When treatment is experienced as collaborative, involves shared decision making and support, other than medication, young people feel more equipped to navigate the liminal space.

The experience of living with vitiligo in Nigeria: A participatory Interpretative Phenomenological Analysis.

Vitiligo is a visible depigmenting skin condition, particularly noticeable on Black skin. There is widespread misunderstanding of the condition. Using a participatory form of Interpretative Phenomenological Analysis (IPA), we conducted eight semi-structured interviews with Nigerians living with vitiligo. Participants described their initial attempts to understand the condition, which typically drew on both traditional illness beliefs, religious influences, and the biomedical disease model. All participants reported experiencing marked stigmatization and discrimination. Participants experienced distress associated with thoughts about the personal meaning of the disease including its impact on their appearance and from concerns about anticipated and direct discrimination. Despite the wide-ranging impact, the participants' narratives also contained references to the development of strategies that maintained wellbeing. This study provides valuable insights into the role of faith and traditional beliefs in both the experience and management of vitiligo in Nigeria. These insights can be used to develop individual and community interventions.

Vocational functioning in young people accessing services for first-episode psychosis and ultra-high risk of psychosis: A longitudinal naturalistic cohort study.

AIMS: Young people with first-episode psychosis (FEP) or at ultra-high risk (UHR) of psychosis often have lower vocational engagement than their peers. This study examines the effect of treatment in early intervention for psychosis services in Australia on engagement in education and employment. METHODS: This is a naturalistic sample of young people aged 12-25 with FEP (n = 1574) and UHR (n = 1515), accessing treatment in the headspace Early Psychosis (hEP) programme. Engagement in education and employment was assessed at baseline and every 90 days in treatment. Mixed effects logistic regression were used to analyse changes over time. RESULTS: On entering the hEP programme, approximately 49% of the young people with FEP and 28% of the young people at UHR status identified as Not in Education, Employment or Training (NEET). The odds of being NEET were reduced by 27% (95% confidence interval = [14, 39]) for every 6 months treatment for the FEP group, but no change in NEET status was observed in the UHR group. In both groups, absence from daily activities was significantly reduced during time in treatment. CONCLUSION: While there are methodological challenges analysing real-world non-control group cohort data, the findings indicate positive effects of the hEP programme on vocational and daily activity engagement for young people with FEP and at UHR status. A large proportion of the young people still identified as NEET after receiving treatment services, suggesting further refinement to ensure targeted and consistent vocational support throughout care.

Exploratory and confirmatory factor analysis of emPHasis-10: The health-related quality-of-life measure in pulmonary hypertension.

The emPHasis-10 is a health-related quality of life (HRQoL) unidimensional measure developed specifically for adults with pulmonary hypertension. The tool has excellent psychometric properties and is well used in research and clinical settings. Its factor structure has not been examined, which may help to identity a complimentary approach to using the measure to examine patient functioning. We performed an exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) on a data set collected from 263 adults with PH recruited from a community setting. The EFA suggested the emPHasis-10 consists of three underlying latent variables, which based on the loading of items, were termed "fatigue" (Items 3, 4, and 5), "independence" (Items 7, 8, 9, and 10), and "breathlessness" (Items 1, 2, and 6). All factors were found to have good internal consistency. "Independence" accounted for most of the variance (29%), followed by "breathlessness" (22%) and "fatigue" (19%). The CFA looked to confirm the fit of a three-factor model. A higher-order model was found to be the best fit consisting of HRQoL as a superordinate factor, for which the association between this factor and the 10 items was mediated through the three latent factors. Further analyses were performed testing the validity of the latent variables revealing all were significantly correlated with self-reported measures of depression, anxiety, health-anxiety, and dyspnea. Our analyses support the emPHasis-10 as a measure of HRQoL, while also proposing the clinical utility of examining the three emergent factors, which could be used to glean additional insight into the respondent's functioning and inform care.

Memory, mood and associated neuroanatomy in individuals with steroid sulphatase deficiency (X-linked ichthyosis).

Steroid sulphatase (STS) cleaves sulphate groups from steroid hormones, and steroid (sulphate) levels correlate with mood and age-related cognitive decline. In animals, STS inhibition or deletion of the associated gene, enhances memory/neuroprotection and alters hippocampal neurochemistry. Little is known about the consequences of constitutive STS deficiency on memory-related processes in humans. We investigated self-reported memory performance (Multifactorial Memory Questionnaire), word-picture recall and recent mood (Kessler Psychological Distress Scale, K10) in adult males with STS deficiency diagnosed with the dermatological condition X-linked ichthyosis (XLI; n = 41) and in adult female carriers of XLI-associated genetic variants (n = 79); we compared results to those obtained from matched control subjects [diagnosed with ichthyosis vulgaris (IV, n = 98) or recruited from the general population (n = 250)]. Using the UK Biobank, we compared mood/memory-related neuroanatomy in carriers of genetic deletions encompassing STS (n = 28) and non-carriers (n = 34,522). We found poorer word-picture recall and lower perceived memory abilities in males with XLI and female carriers compared with control groups. XLI-associated variant carriers and individuals with IV reported more adverse mood symptoms, reduced memory contentment and greater use of memory aids, compared with general population controls. Mood and memory findings appeared largely independent. Neuroanatomical analysis only indicated a nominally-significantly larger molecular layer in the right hippocampal body of deletion carriers relative to non-carriers. In humans, constitutive STS deficiency appears associated with mood-independent impairments in memory but not with large effects on underlying brain structure; the mediating psychobiological mechanisms might be explored further in individuals with XLI and in new mammalian models lacking STS developmentally.

The experiences of individuals with body dysmorphic disorder: A systematic review and thematic synthesis of qualitative research.

Body Dysmorphic Disorder (BDD) is a distressing psychological condition where an individual is preoccupied by a perceived issue with their appearance. Qualitative studies enable nuanced aspects of BDD phenomenology to be investigated. The current systematic review used thematic synthesis to integrate the findings from the extant qualitative studies. Searches were run on six databases to identify studies that had sought to describe the experience of individuals with BDD. PRISMA guidance was followed and ten articles were identified for inclusion. The quality of each article was appraised and thematic synthesis was conducted to generate novel and summative themes. Three superordinate themes were created: 'self-objectification and the view of self'; 'control and protecting the self'; and 'sociocultural influences and the impact of others in BDD'. Shame and self-disgust emerged as key experiential elements of BDD. The findings of the review suggest that self-objectification theory and possibly models of self-compassion are theoretically relevant to understanding the experience of individuals presenting with BDD. Current interventions may benefit from consideration of these theoretical models when seeking to improve efficacy.

A polygenic risk score for alcohol-associated cirrhosis among heavy drinkers with European ancestry.

BACKGROUND: Polygenic Risk Scores (PRS) based on results from genome-wide association studies offer the prospect of risk stratification for many common and complex diseases. We developed a PRS for alcohol-associated cirrhosis by comparing single-nucleotide polymorphisms among patients with alcohol-associated cirrhosis (ALC) versus drinkers who did not have evidence of liver fibrosis/cirrhosis. METHODS: Using a data-driven approach, a PRS for ALC was generated using a meta-genome-wide association study of ALC (N=4305) and an independent cohort of heavy drinkers with ALC and without significant liver disease (N=3037). It was validated in 2 additional independent cohorts from the UK Biobank with diagnosed ALC (N=467) and high-risk drinking controls (N=8981) and participants in the Indiana Biobank Liver cohort with alcohol-associated liver disease (N=121) and controls without liver disease (N=3239). RESULTS: A 20-single-nucleotide polymorphisms PRS for ALC (PRSALC) was generated that stratified risk for ALC comparing the top and bottom deciles of PRS in the 2 validation cohorts (ORs: 2.83 [95% CI: 1.82 -4.39] in UK Biobank; 4.40 [1.56 -12.44] in Indiana Biobank Liver cohort). Furthermore, PRSALC improved the prediction of ALC risk when added to the models of clinically known predictors of ALC risk. It also stratified the risk for metabolic dysfunction -associated steatotic liver disease -cirrhosis (3.94 [2.23 -6.95]) in the Indiana Biobank Liver cohort -based exploratory analysis. CONCLUSIONS: PRSALC incorporates 20 single-nucleotide polymorphisms, predicts increased risk for ALC, and improves risk stratification for ALC compared with the models that only include clinical risk factors. This new score has the potential for early detection of heavy drinking patients who are at high risk for ALC.

Allosteric coupling asymmetry mediates paradoxical activation of BRAF by type II inhibitors.

The type II class of RAF inhibitors currently in clinical trials paradoxically activate BRAF at subsaturating concentrations. Activation is mediated by induction of BRAF dimers, but why activation rather than inhibition occurs remains unclear. Using biophysical methods tracking BRAF dimerization and conformation, we built an allosteric model of inhibitor-induced dimerization that resolves the allosteric contributions of inhibitor binding to the two active sites of the dimer, revealing key differences between type I and type II RAF inhibitors. For type II inhibitors the allosteric coupling between inhibitor binding and BRAF dimerization is distributed asymmetrically across the two dimer binding sites, with binding to the first site dominating the allostery. This asymmetry results in efficient and selective induction of dimers with one inhibited and one catalytically active subunit. Our allosteric models quantitatively account for paradoxical activation data measured for 11 RAF inhibitors. Unlike type II inhibitors, type I inhibitors lack allosteric asymmetry and do not activate BRAF homodimers. Finally, NMR data reveal that BRAF homodimers are dynamically asymmetric with only one of the subunits locked in the active αC-in state. This provides a structural mechanism for how binding of only a single αC-in inhibitor molecule can induce potent BRAF dimerization and activation.

Identifying and managing treatment resistance early with the integration of a clozapine clinic within an early intervention for psychosis service.

BACKGROUND: Despite being the most effective antipsychotic medication for treatment-resistant psychosis, clozapine is often under-utilized with long delays to initiation. AIMS: This study aimed to determine whether the integration of a clozapine clinic within an early intervention for psychosis service resulted in a change in the rate and time to initiation of clozapine, the number of trials of different antipsychotic medications prior to clozapine, community initiation and discontinuation rates. METHODS: A clozapine clinic was established in the Early Psychosis Prevention and Intervention Centre in Melbourne. This was a pre- and post-evaluation study design. The 'clozapine clinic' cohort included those who commenced on clozapine from 01 January 2016 to 30 June 2018. RESULTS: Prior to the clozapine clinic, 24 young people commenced clozapine over the 30-month period compared to 36 in the clozapine clinic cohort (RR = 1.30, 95% CI: 0.75-2.28, p = .32). In the pre-clozapine clinic cohort, 4.6% of all those with a first episode of psychosis were commenced on clozapine compared to 6% in the clozapine clinic cohort. Prior to the clozapine clinic, the median time to the commencement of clozapine was 72 weeks (IQR: 38, 87), compared to 53.5 weeks (IQR: 38, 81.5) in the clozapine clinic (Z = -0.86, p = .393). The mean number of different antipsychotic medications prior to commencing clozapine remained stable at 3.2 (SD ± 1.1) in both cohorts (t = -0.20, p = .841). There was a lower rate of discontinuation in the clozapine clinic (43.5% vs. 14.7%, HR = 0.30, 95% CI: 0.09-0.98, p = .046). CONCLUSIONS: While this study was underpowered and there are limitations to the naturalistic study design, the findings lend support to the integration of a clozapine clinic within early intervention for psychosis services.

Validating cognitive screening in young people with first-episode psychosis: The CogScreen protocol.

AIM: Cognitive impairments are a core feature of first-episode psychosis (FEP) and one of the strongest predictors of long-term psychosocial functioning. Cognition should be assessed and treated as part of routine clinical care for FEP. Cognitive screening offers the opportunity to rapidly identify and triage those in most need of cognitive support. However, there are currently no validated screening measures for young people with FEP. CogScreen is a hybrid effectiveness-implementation study which aims to evaluate the classification accuracy (relative to a neuropsychological assessment as a reference standard), test-retest reliability and acceptability of two cognitive screening tools in young people with FEP. METHODS: Participants will be 350 young people (aged 12-25) attending primary and specialist FEP treatment centres in three large metropolitan cities (Adelaide, Sydney, and Melbourne) in Australia. All participants will complete a cross-sectional assessment over two sessions including two cognitive screening tools (Screen for Cognitive Impairment in Psychiatry and Montreal Cognitive Assessment), a comprehensive neuropsychological assessment battery, psychiatric and neurodevelopmental assessments, and other supplementary clinical measures. To determine the test-retest reliability of the cognitive screening tools, a subset of 120 participants will repeat the screening measures two weeks later. RESULTS: The protocol, rationale, and hypotheses for CogScreen are presented. CONCLUSIONS: CogScreen will provide empirical evidence for the validity and reliability of two cognitive screening tools when compared to a comprehensive neuropsychological assessment. The screening measures may later be incorporated into clinical practice to assist with rapid identification and treatment of cognitive deficits commonly experienced by young people with FEP.

Longitudinal Patterns of Multimorbidity in Gulf War Era Veterans With and Without Gulf War Illness.

Objectives: To examine whether severe Gulf War illness (SGWI) case status was associated with longitudinal multimorbidity patterns. Methods: Participants were users of the Veteran Health Administration Health Care System drawn from the Gulf War Era Cohort and Biorepository (n = 840). Longitudinal measures of multimorbidity were constructed using (1) electronic health records (Charlson Comorbidity Index; Elixhauser; and Veterans Affairs Frailty Index) from 10/1/1999 to 6/30/2023 and (2) self-reported medical conditions (Deficit Accumulation Index) since the war until the survey date. Accelerated failure time models examined SGWI case status as a predictor of time until threshold level of multimorbidity was reached, adjusted for age and sociodemographic and military characteristics. Results: Models, adjusted for covariates, revealed that (1) relative to the SWGI- group, the SGWI+ group was associated with an accelerated time for reaching each threshold and (2) the relationship between SGWI and each threshold was not moderated by age. Discussion: Findings suggest that veterans with SGWI experienced accelerated aging.

Does Acinetobacter calcoaceticus glucose dehydrogenase produce self-damaging H2O2?

The soluble glucose dehydrogenase (sGDH) from Acinetobacter calcoaceticus has been widely studied and is used, in biosensors, to detect the presence of glucose, taking advantage of its high turnover and insensitivity to molecular oxygen. This approach, however, presents two drawbacks: the enzyme has broad substrate specificity (leading to imprecise blood glucose measurements) and shows instability over time (inferior to other oxidizing glucose enzymes). We report the characterization of two sGDH mutants: the single mutant Y343F and the double mutant D143E/Y343F. The mutants present enzyme selectivity and specificity of 1.2 (Y343F) and 5.7 (D143E/Y343F) times higher for glucose compared with that of the wild-type. Crystallographic experiments, designed to characterize these mutants, surprisingly revealed that the prosthetic group PQQ (pyrroloquinoline quinone), essential for the enzymatic activity, is in a cleaved form for both wild-type and mutant structures. We provide evidence suggesting that the sGDH produces H2O2, the level of production depending on the mutation. In addition, spectroscopic experiments allowed us to follow the self-degradation of the prosthetic group and the disappearance of sGDH's glucose oxidation activity. These studies suggest that the enzyme is sensitive to its self-production of H2O2. We show that the premature aging of sGDH can be slowed down by adding catalase to consume the H2O2 produced, allowing the design of a more stable biosensor over time. Our research opens questions about the mechanism of H2O2 production and the physiological role of this activity by sGDH.

Online compassion-based self-help for depression in people with skin conditions: a feasibility study.

BACKGROUND: There is a need to develop psychological interventions for depression in people with skin conditions. This study aimed to investigate the acceptability, feasibility, and effects of an online compassion-based self-help intervention for depression in people with skin conditions. METHODS: Adult participants (n = 34) with skin conditions and mild-moderate depressive symptoms were invited to undertake a six-week, compassion-based online intervention for depression with email support. Engagement with the intervention was monitored, along with time spent facilitating the intervention, and participant feedback was collected each week and post-intervention. Pre-post changes in depression, self-compassion and dermatological quality of life were also assessed. RESULTS: The intervention was started by 25 participants and completed by 13. Feedback scores indicated that the website was evaluated positively and that the sessions had positive impacts on participants. Participants appreciated the skin-specific aspects of the intervention but varied as to which of the compassion-based exercises they found helpful. The online intervention was feasible to provide and facilitate, and treatment completers showed improvements in depression, quality of life and self-compassion. CONCLUSIONS: The online compassion-based intervention holds promise as a treatment for depression in people with skin conditions. Recommendations are made for future research and further development of the intervention. TRIAL REGISTRATION: This study was registered at ClinicalTrials.gov on 21 October 2019, NCT04132973.

Dynamic Opportunities for Medical Students to Assume the Roles of "Medical Teacher".

The traditional undergraduate medical education curriculum focuses on bolstering knowledge for practice and building clinical skills. However, as future clinicians, medical students will be tasked with teaching throughout their careers, first as residents and then as attendings. Here, we describe teaching opportunities for students that foster their development as future teachers and potential clinician educators. These offerings are diverse in their focus and duration and are offered across various levels of the curriculum - including course-based learning, longitudinal electives, and extra-curricular opportunities for medical students who have a passion for teaching.

Cross-species spill-over potential of the H9N2 bat influenza A virus.

In 2017, a novel influenza A virus (IAV) was isolated from an Egyptian fruit bat. In contrast to other bat influenza viruses, the virus was related to avian A(H9N2) viruses and was probably the result of a bird-to-bat transmission event. To determine the cross-species spill-over potential, we biologically characterize features of A/bat/Egypt/381OP/2017(H9N2). The virus has a pH inactivation profile and neuraminidase activity similar to those of human-adapted IAVs. Despite the virus having an avian virus-like preference for α2,3 sialic acid receptors, it is unable to replicate in male mallard ducks; however, it readily infects ex-vivo human respiratory cell cultures and replicates in the lungs of female mice. A/bat/Egypt/381OP/2017 replicates in the upper respiratory tract of experimentally-infected male ferrets featuring direct-contact and airborne transmission. These data suggest that the bat A(H9N2) virus has features associated with increased risk to humans without a shift to a preference for α2,6 sialic acid receptors.

A mixed-methods evaluation of patients' views on primary care multi-disciplinary teams in Scotland.

BACKGROUND: Expanding primary care multi-disciplinary teams (MDTs) was a key component of the 2018 Scottish GP contract, with over 4,700 MDT staff appointed since then. AIM: To explore patients' views on primary care MDT expansion in Scotland. DESIGN AND METHODS: (1) Survey of patients recently consulting a GP in deprived-urban, affluent-urban and remote/rural areas, assessing awareness of five MDT roles and attitudes towards receptionist signposting; (2) 30 individual interviews exploring MDT-care experiences. RESULTS: Of 1,053 survey respondents, most were unaware of the option of MDT rather than GP consultations for three out of five roles (69% unaware of link worker appointments; 68% mental health nurse; 58% pharmacist). Reception signposting was less popular in deprived-urban areas (34% unhappy vs 29% in remote/rural vs 21% affluent-urban; P<0.001), and in patients with multimorbidity (31% unhappy vs 24% in non-multimorbid; P<0.05).Two-thirds of interviewees had multimorbidity and almost all reported positive MDT-care experiences. However, MDT-care was generally seen as a supplement rather than a substitute for GP care. Around half of patients expressed concerns about reception signposting. These patients were more likely to also express concerns about GP access in general. Both of these concerns were more common in deprived-urban areas than in remote/rural or affluent-urban areas. CONCLUSION: MDT-care has expanded in Scotland with limited patient awareness. Although patients understand its potential value, many patients are unhappy with reception signposting to first-contact MDT care, especially those in deprived-urban areas living with multimorbidity. This represents a barrier to the aims of the new GP contract.

How healthcare systems are experienced by autistic adults in the United Kingdom: A meta-ethnography.

LAY ABSTRACT: Autistic adults are more likely to experience mental and physical health difficulties, and yet can find it difficult to get the support that they need. A meta-ethnographic approach was used to review the existing research on autistic adults' experiences of accessing healthcare. Four databases were searched for qualitative and mixed-method studies which looked at the experiences of autistic adults who did not also have a learning disability when using healthcare services in the United Kingdom. Fifteen papers met the criteria to be included, and seven steps were used to analyse the information and develop new themes. Three main themes were identified: Professionals' lack of knowledge can be damaging, Need to reduce processing demands and Adaptation to improve engagement. This review highlights how damaging misdiagnosis, inappropriate treatment, overwhelming environments and systems that are difficult to access can have on the well-being of autistic adults. Limited knowledge and understanding about autism knowledge among healthcare professionals along with autistic adult's own communication and sensory differences indicate that there is a need for improved training developed with autistic adults and adaptations.

Burden of disease and treatment patterns in patients with vitiligo: findings from a national longitudinal retrospective study in the UK.

BACKGROUND: UK studies examining vitiligo burden and vitiligo-related healthcare resource utilization (HCRU) are lacking. OBJECTIVE: To describe the incidence and prevalence of vitiligo, the demographic and clinical characteristics of patients with vitiligo, vitiligo burden, HCRU, incidence of mental health comorbidities and management strategies, including treatment patterns. METHODS: This retrospective study used UK Clinical Practice Research Datalink and Hospital Episode Statistics databases to analyse patients with vitiligo from 1 January 2010 to 31 December 2021. RESULTS: Among 17 239 incident patients, mean incidence of vitiligo was 0.16 (2010-2021) per 1000 person-years [PY; range 0.10 (2020-COVID-19) to 0.19 (2010/2013/2018)]; among 66 217 prevalent patients, prevalence increased from 0.21% (2010) to 0.38% (2021). The most common comorbidities recorded after vitiligo diagnosis were diabetes (19.4%), eczema (8.9%), thyroid disease (7.5%) and rheumatoid arthritis (6.9%). Mental health diagnoses recorded at any time included depression and/or anxiety (24.6%), depression (18.5%), anxiety (16.0%) and sleep disturbance (12.7%), and recorded after vitiligo diagnosis in 6.4%, 4.4%, 5.5% and 3.9%, respectively. Mental health comorbidities were more common in White (e.g. depression and/or anxiety 29.0%) than in Black (18.8%) and Asian (16.1%) patients. In adolescents, depression and/or anxiety was most commonly diagnosed after a vitiligo diagnosis than before (7.4% vs. 1.8%). Healthcare resources were used most frequently in the first year after vitiligo diagnosis (incident cohort), typically dermatology-related outpatient appointments (101.9/100 PY) and general practitioner consultations (97.9/100 PY). In the year after diagnosis, 60.8% of incident patients did not receive vitiligo-related treatment (i.e. topical corticosteroids, topical calcineurin inhibitors, oral corticosteroids or phototherapy), increasing to 82.0% the next year; median time from diagnosis to first treatment was 34.0 months (95% confidence interval 31.6-36.4). Antidepressants and/or anxiolytics were recorded for 16.7% of incident patients in the year after diagnosis. In 2019, 85.0% of prevalent patients did not receive vitiligo-related treatments. CONCLUSION: Most patients were not on vitiligo-related treatments within a year of diagnosis, with the time to first treatment exceeding 2 years, suggesting that vitiligo may be dismissed as unimportant. New effective treatments, early initiation and psychological intervention and support are needed to reduce the vitiligo burden on patients.

Vitiligo is a chronic disease in which cells that produce the skin pigment called melanin are attacked, resulting in white or pale patches of skin. It is diagnosed in an estimated 0.2­0.8% of people in Europe. This study aimed to describe how many new cases of vitiligo were recorded between 2010 and 2021 in the UK and the overall percentage of people with vitiligo. Linked national general practitioner (GP) and hospital-based records containing information on medical diagnoses, admissions and hospital visits were used. Records of other diseases and conditions, including mental health conditions, in combination with healthcare service use and treatment prescribed to patients with vitiligo, were studied to describe the impact of living with vitiligo. It was found that 0.16 new cases of vitiligo were recorded per 1000 person-years (for example, 0.16 new cases would have been recorded if 1000 people were followed for 1 year or if 100 people were all followed for 10 years) between 2010 and 2021. In 2021, 0.4% of the population studied had vitiligo. In the 5 years after a new diagnosis of vitiligo, the most common other diseases recorded were diabetes (19%), eczema (9%), thyroid disease (8%) and rheumatoid arthritis (7%), and the most common mental health conditions were depression and/or anxiety (25%). In the year after diagnosis, GP and dermatology outpatient visits were the most common type of medical services used. In 2019, 85% of all individuals with vitiligo were not receiving any vitiligo-related treatment (such as creams or phototherapy). It took approximately 34 months from diagnosis of vitiligo to the start of first treatment. The results suggest that new effective treatments and psychological interventions are needed to reduce the burden of vitiligo.
