Abstract Background Eosinophilic esophagitis is a chronic inflammatory disorder of the esophagus. This real-world study used patient and physician surveys to describe the clinical characteristics and disease burden of eosinophilic esophagitis—overall and in a subgroup of patients with dysphagia despite treatment. Methods Data analyzed in this study were collected in 2020 from US and EU patients with eosinophilic esophagitis. Eligible patients were aged ≥ 12 years with a diagnosis of eosinophilic esophagitis, had an esophageal count of ≥ 15 eosinophils/high-power field at diagnosis, and were currently prescribed treatment for eosinophilic esophagitis. Results Overall, 1001 patients were included, of whom 356 (36%) had dysphagia despite treatment. Demographics and clinical characteristics were similar in both populations. The severity of eosinophilic esophagitis was mild in more patients overall (69%) versus those with dysphagia despite treatment (48%). Patient disease history was similar in both populations, with some exceptions: common patient-reported symptoms were dysphagia (70% and 86%) and heartburn/acid reflux (55% and 49%), and common physician-reported symptoms were dysphagia (75% and 91%) and food impaction (46% and 52%). Treatment history was similar in both populations; overall, the most common treatments were proton pump inhibitors (83%) and topical corticosteroids (51%). Patients reported slightly more days with symptoms, higher impacts on activities of daily living, and slightly higher anxiety or depression in the dysphagia-despite-treatment population versus the overall population. Conclusions Eosinophilic esophagitis presents severe symptoms and comorbidities that substantially impact patients’ well-being and quality of life. Greater awareness of and novel treatments for eosinophilic esophagitis are needed.

Abstract Background Heart failure (HF) with preserved or mildly reduced ejection fraction includes a heterogenous group of patients. Reclassification into distinct phenogroups to enable targeted interventions is a priority. This study aimed to identify distinct phenogroups, and compare phenogroup characteristics and outcomes, from electronic health record data. Methods 2,187 patients admitted to five UK hospitals with a diagnosis of HF and a left ventricular ejection fraction ≥ 40% were identified from the NIHR Health Informatics Collaborative database. Partition-based, model-based, and density-based machine learning clustering techniques were applied. Cox Proportional Hazards and Fine-Gray competing risks models were used to compare outcomes (all-cause mortality and hospitalisation for HF) across phenogroups. Results Three phenogroups were identified: (1) Younger, predominantly female patients with high prevalence of cardiometabolic and coronary disease; (2) More frail patients, with higher rates of lung disease and atrial fibrillation; (3) Patients characterised by systemic inflammation and high rates of diabetes and renal dysfunction. Survival profiles were distinct, with an increasing risk of all-cause mortality from phenogroups 1 to 3 (p

Abstract Aims Population‐wide, person‐level, linked electronic health record data are increasingly used to estimate epidemiology, guide resource allocation, and identify events in clinical trials. The accuracy of data from NHS Digital (now part of NHS England) for identifying hospitalization for heart failure (HHF), a key HF standard, is not clear. This study aimed to evaluate the accuracy of NHS Digital data for identifying HHF. Methods and results Patients experiencing at least one HHF, as determined by NHS Digital data, and age‐ and sex‐matched patients not experiencing HHF, were identified from a prospective cohort study and underwent expert adjudication. Three code sets commonly used to identify HHF were applied to the data and compared with expert adjudication (I50: International Classification of Diseases‐10 codes beginning I50; OIS: Clinical Commissioning Groups Outcomes Indicator Set; and NICOR: National Institute for Cardiovascular Outcomes Research, used as the basis for the National Heart Failure Audit in England and Wales). Five hundred four patients underwent expert adjudication, of which 10 (2%) were adjudicated to have experienced HHF. Specificity was high across all three code sets in the first diagnosis position {I50: 96.2% [95% confidence interval (CI) 94.1–97.7%]; NICOR: 93.3% [CI 90.8–95.4%]; OIS: 95.6% [CI 93.3–97.2%]} but decreased substantially as the number of diagnosis positions expanded. Sensitivity [40.0% (CI 12.2–73.8%)] and positive predictive value (PPV) [highest with I50: 17.4% (CI 8.1–33.6%)] were low in the first diagnosis position for all coding sets. PPV was higher for the National Heart Failure Audit criteria, albeit modestly [36.4% (CI 16.6–62.2%)]. Conclusions NHS Digital data were not able to accurately identify HHF and should not be used in isolation for this purpose.

Calcific tendinopathy in the gluteus medius is uncommon and sporadically reported. It may be asymptomatic or present with acute or chronic pain. Pain is usually isolated to the lateral hip overlying the gluteal muscles or greater trochanter. We present a rare case of gluteus medius calcific tendonitis as a cause of severe anterior hip pain. Given the atypical local and clinical presentation these can be often misdiagnosed as septic arthritis or fracture which may lead to overtreatment and even unnecessary surgery. This article will detail the clinical presentation, imaging findings, and clinical course following treatment. This will facilitate the clinician in making a timely diagnosis and establishing an effective treatment course.

Abstract Introduction CHAMOMILE (CHaracteristics and impact of flares on clinicAl and econoMic OutcoMes In patients with systemic Lupus Erythematosus [SLE]) examined how flares in the year of SLE diagnosis impact future disease activity and damage, productivity, healthcare resource utilization (HCRU), and costs in patients with SLE in Germany. Methods CHAMOMILE was a retrospective cohort study of adults with an SLE diagnosis in the German Sickness Fund Database from 1 July 2010 to 31 December 2013. Patients were classified according to their greatest flare severity during the baseline year (none, mild, or moderate/severe). The number and severity of flares were assessed annually over 5–8.5 follow-up years, along with SLE organ/system damage, treatments, work disability, and HCRU metrics. Results Of 2088 patients (84.6% female; mean age [standard deviation] 51.4 [16.1] years; mean follow-up 6.8 [2.1] years), 34.3% (n = 716) were flare-free, 29.8% (n = 622) had mild flares, and 35.9% (n = 750) had moderate/severe flares at baseline. Baseline flare severity was related to future flares: rates during follow-up were higher in patients with moderate/severe baseline flares compared with those with mild or no baseline flares (89.6 vs 78.5 and 44.2 flares/100 patient years, respectively). Overall, 80.2% (n = 1675) of patients received glucocorticoids at least once during baseline and follow-up. Patients’ HCRU was generally greatest in their baseline year. Costs were highest in patients with moderate/severe baseline flares. Conclusion Baseline flare severity provided insight into a patient’s disease course and the clinical and economic burden of SLE over time, highlighting the ramifications of uncontrolled disease for patients with SLE.

Abstract Background Indigenous children in colonised nations experience high rates of health disparities linked to historical trauma resulting from displacement and dispossession, as well as ongoing systemic racism. Skin infections and their complications are one such health inequity, with the highest global burden described in remote-living Australian Aboriginal and/or Torres Strait Islander (hereafter respectfully referred to as Aboriginal) children. Yet despite increasing urbanisation, little is known about the skin infection burden for urban-living Aboriginal children. More knowledge is needed to inform service provision, treatment guidelines and community-wide healthy skin strategies. In this pilot study, we aimed to test the feasibility and design of larger multi-site observational studies, provide initial descriptions of skin disease frequency and generate preliminary hypotheses of association. Methods This project has been co-designed with local (Noongar) Elders to provide an Australian-first description of skin health and disease in urban-living Aboriginal children. In collaboration with an urban Aboriginal Community Controlled Health Organisation (Derbarl Yerrigan Health Service), we conducted a week-long cross-sectional observational cohort study of Aboriginal children (0–18 years) recruited from the waiting room. Participants completed a questionnaire, skin examination, clinical photos, and swabs and received appropriate treatment. We assessed the feasibility and impact of the pilot study. Results From 4 to 8 October 2021, we recruited 84 Aboriginal children of whom 80 (95%) were urban-living. With a trusted Aboriginal Health Practitioner leading recruitment, most parents (or caregivers) who were approached consented to participate. Among urban-living children, over half (45/80, 56%) of parents described a current concern with their child’s skin, hair and/or nails; and one-third (26/80, 33%) reported current itchy skin. Using a research-service model, 27% (21/79) of examined urban-living participants received opportunistic same-day treatment and 18% (14/79) were referred for later review. Conclusions This co-designed pilot study to understand skin health in urban-living Aboriginal children was feasible and acceptable, with high study participation and subsequent engagement in clinical care observed. Co-design and the strong involvement of Aboriginal people to lead and deliver the project was crucial. The successful pilot has informed larger, multi-site observational studies to more accurately answer questions of disease burden and inform the development of healthy skin messages for urban-living Aboriginal children.

This study explores the relationship between blood eosinophils and CKD progression among patients in a real-world setting.Methods: This retrospective study analyzed data obtained from the Optum® de-identified electronic health records dataset in the United States. Patients diagnosed with CKD stage 3 or 4 (International Classification of Diseases diagnosis code or estimated glomerular filtration rate [eGFR] < 60 mL/min) between January 2011 and March 2018 were included and followed until progression to the next CKD stage, death, or dropout. The primary objective of this study was to assess the relationship between blood eosinophil counts (bEOS) and CKD progression, adjusting for clinical and demographic features as well as known risk factors for CKD stages 3– 4. The primary outcomes were CKD progression and all-cause mortality.Results: We found that high eosinophilic levels (bEOS ≥ 300 cells/μL) were associated with CKD progression from stage 3 to stages 4 or 5 (hazard ratio [HR] ranging from 1.30 to 1.50) and from stages 4 to 5 (HR ranging from 1.28 to 1.50). Among patients with CKD progression, those with blood eosinophils ≥ 300 cells/μL appeared to have a relatively lower eGFR, higher all-cause mortality, and reduced time to CKD progression and death than those with < 300 cells/μL. Factors including sex, race, hypertension, anemia, and treatments for cardiovascular and hematopoietic drugs were associated with CKD progression.Conclusion: Elevated eosinophils may increase the risk for CKD progression. Larger studies are needed to assess whether the risk of mortality is increased among patients with elevated eosinophils.Keywords: eosinophilic inflammation, renal insufficiency, glomerular filtration rate

Background: Real-world data describing the impact of incident bullous pemphigoid (BP) on patients and health care resource utilization (HCRU) are limited. Objective: To examine characteristics, treatment patterns, HCRU, and costs for incident BP. Methods: Retrospective analysis of 2015 to 2019 US health insurance claims for patients ≥18 years with an incident BP diagnosis. Patients with BP were matched to those without on demographic and clinical characteristics. Statistics were descriptive. Results: The mean Charlson Comorbidity Index score was higher for patients with BP (n = 1108) than without (n = 4621) at baseline (mean [SD]: 3.3 [2.7] vs 2.8 [2.4]) and during follow-up (5.0 [4.9] vs 3.7 [3.0]). Hypertension, diabetes, skin ulcers, chronic pulmonary disease, dyslipidemia, sleep disorders, and congestive heart failure were higher with BP. Most patients with BP received antibiotics (>80%) and/or corticosteroids (>90%). Hospitalizations were more common (44.0% vs 17.1%) and monthly all-cause health care costs more than double ($3214 vs $1353) in patients with BP than without. Limitations: Diagnoses were based on billing codes. HCRU claims data may not reflect the true number of encounters. Conclusion: Incident BP is associated with considerable morbidity, HCRU, and costs. More effective, targeted treatments are needed to improve quality of life, while minimizing exposure to systemic corticosteroids.

Abstract Introduction Alopecia areata (AA) can negatively affect quality of life (QoL) and is associated with increased prevalence of anxiety and depression (vs people without AA). This study compared physician-assessed and patient self-rated severity of AA in a European sample and described the patient-reported burden of AA stratified by physician-assessed severity. Methods Real-world data were collected from the Adelphi Real World AA Disease Specific Programme™, a retrospective point-in-time cross-sectional survey of dermatologists and their adult patients with AA in five European countries (France, Germany, Italy, Spain, UK). Physicians provided clinical data and an AA severity assessment, according to their own definition of ‘mild’, ‘moderate’ and ‘severe’. Patients were invited to provide their perception of AA severity and completed patient-reported outcome (PRO) questionnaires, including Skindex-16 for AA (Skindex-16 AA), EuroQol-5-dimension questionnaire 5-level (EQ-5D-5L), Hospital Anxiety and Depression Scale and the Work Productivity and Activity Impairment Questionnaire. Results Data for 2083 patients were collected by 239 physicians; 561 of these patients completed PRO questionnaires. In 78.5% of cases with available data (N = 549), there was alignment between patient and physician-rated AA severity (severity was rated higher by physicians in 15.7% of cases, by patients in 5.8% of cases). Data from all PRO instruments showed an increase in patient-reported burden and work and activity impairment with increasing physician-rated AA severity. For the Skindex-16 AA, the Emotions scale had the worst scores; anxiety/depression was the EQ-5D-5L dimension with the highest percentages of patients reporting any perceived problem. Conclusions These data highlight the significant impact that AA can have beyond hair loss, especially for patients with severe AA. There was substantial physician–patient alignment on severity assessment. Higher physician-rated AA severity was associated with higher levels of patient-reported disease burden, including anxiety and depression, and work and activity impairment. These data may help inform appropriate treatment strategies.

Multimorbidity is an emerging challenge for health systems globally. It is commonly defined as the co-occurrence of two or more chronic conditions in one person, but its meaning remains a lively area of academic debate, and the utility of the concept beyond high-income settings is uncertain. This article presents the findings from an interdisciplinary research initiative that drew together 60 academic and applied partners working in 10 African countries to answer the questions: how useful is the concept of multimorbidity within Africa? Can the concept be adapted to context to optimise its transformative potentials? During a three-day concept-building workshop, we investigated how the definition of multimorbidity was understood across diverse disciplinary and regional perspectives, evaluated the utility and limitations of existing concepts and definitions, and considered how to build a more context-sensitive, cross-cutting description of multimorbidity. This iterative process was guided by the principles of grounded theory and involved focus- and whole-group discussions during the workshop, thematic coding of workshop discussions, and further post-workshop development and refinement. Three thematic domains emerged from workshop discussions: the current focus of multimorbidity on constituent diseases; the potential for revised concepts to centre the priorities, needs, and social context of people living with multimorbidity (PLWMM); and the need for revised concepts to respond to varied conceptual priorities amongst stakeholders. These themes fed into the development of an expanded conceptual model that centres the catastrophic impacts multimorbidity can have for PLWMM, families and support structures, service providers, and health systems.

Globally, Indigenous children have historical and contemporary connections with government child protection services that have caused significant harm to their long-term health and wellbeing. Innovative, culturally secure and recovery focussed service provision is required. This paper describes a research protocol that has been designed by Indigenous researchers led by Indigenous Elders, to explore culturally secure care planning and service delivery in out-of-home care agencies in Australia. Using participatory action research methods, we will collect data using a variety of forums, including focus groups and semi-structured interviews. These data will explore the challenges for out-of-home care agencies in providing culturally secure care-planning, cultural activity and resources, and explore solutions to address factors that influence health and can assist to redress social inequities for Indigenous children. We aim to recruit approximately 100 participants for the qualitative study and 40 participants for the quantitative survey. Study participants will initially be recruited using purposive sampling, and as the study progresses will be recruited using a mixture of purposive and convenience sampling techniques. The rich data that this study is expected to yield, will inform ways to collect cultural information about Indigenous children and ways to provide cultural connections and activities that will have benefit to Indigenous children and families, and a broad range of social services.

Despite the vibrant and growing island studies scholarship exploring the unique characteristics of Islands and Islandness, which is both multidisciplinary and interdisciplinary, there has been little research into the unique characteristics associated with the appreciation of the Rule of Law and island identity in an island context. Similarly, although within legal scholarship there has been much exploration at international, European, and national levels of the importance of appreciation of the Rule of Law and its role in helping to reduce the risk of arbitrariness, there has been little consideration in an island context of why the importance of the appreciation of the Rule of Law matters. Building upon both fields of scholarship, the present article uses the Isle of Man as a lens to explore, firstly, why the importance of the appreciation of the Rule of Law in an Island context matters from a legal perspective. Secondly, how exploring the unique characteristics associated with the appreciation of the Rule of Law in an island context provides a greater understanding of the uniqueness of island identity and islandness. The present article is therefore a novel contribution to legal scholarly literature and a timely addition to island study literature.

Abstract Continental-scale expansion of the East Antarctic Ice Sheet during the Eocene-Oligocene Transition (EOT) is one of the largest non-linear events in Earth’s climate history. Declining atmospheric carbon dioxide concentrations and orbital variability triggered glacial expansion and strong feedbacks in the climate system. Prominent among these feedbacks was the repartitioning of biogeochemical cycles between the continental shelves and the deep ocean with falling sea level. Here we present multiple proxies from a shallow shelf location that identify a marked regression and an elevated flux of continental-derived organic matter at the earliest stage of the EOT, a time of deep ocean carbonate dissolution and the extinction of oligotrophic phytoplankton groups. We link these observations using an Earth System model, whereby this first regression delivers a pulse of organic carbon to the oceans that could drive the observed patterns of deep ocean dissolution and acts as a transient negative feedback to climate cooling.

Globally, COPD is currently the third leading cause of mortality.Research Question: 1) To determine the prevalence and burden of symptoms and concerns, and 2) determine predicting factors of symptom burden among patients with COPD.Methods: A cross-sectional survey was conducted at eight primary care sites in Western Cape. We collected socio-demographic data (age, gender, smoking status, number of missed doses of prescribed medication in the last seven days) and clinical data (PEF and KPS). The Memorial Symptom Assessment Scale (MSAS), the Medical Outcomes Study, Social Support Survey (MOS-SSS), the London Chest Activity of Daily Living Scale (LCADLS) and the COPD Assessment Test (CAT) (impairment on person’s life) were administered to patients. We conducted ordered logistic regression analysis to assess factors associated with the burden of symptoms. MSAS subscales: 1) Global symptom distress index, 2) physical symptom distress and 3) psychological symptom distress were dependent outcomes. We constructed three ordinal logistic regression models for each of the three subscales. Covariates were MOS-SSS, LCADLS, CAT, demographic and clinical variables.Results: We recruited n=387 patients, mean age 59.5 years, 53.0% female. In multivariate analysis, each of the three models (ie, global, psychological and physical symptom distress) was positively associated with impairment on person’s life p< 0.001, difficulty to perform activities of daily living p< 0.001, and low social support p< 0.001. Old age was associated with lower global symptom distress (p=0.004), psychological and (0.014) physical distress (0.005). Missing 1 or more doses of medication was associated with higher levels of global (0.004) and physical (0.005) symptom distress.Interpretation: The high prevalence and burden of physical and psychological symptoms provides strong evidence of the need for integrating person-centred assessment and management of symptoms in primary care settings.Keywords: chronic lung disease, chronic obstructive pulmonary disease, symptom burden, symptom distress, symptom prevalence

Abstract Introduction This analysis compared healthcare resource use (HCRU) and costs associated with incident organ damage in a cohort of adult patients with systemic lupus erythematosus (SLE). Methods Incident SLE cases were identified (Clinical Practice Research Datalink [CPRD] and Hospital Episode Statistics-linked healthcare databases; January 1, 2005–June 30, 2019). Annual incidence of 13 organ damage domains was calculated from SLE diagnosis through follow-up. Annualized HCRU and costs were compared between organ damage and non-organ damage patient groups using generalized estimating equations. Results A total of 936 patients met the inclusion criteria for SLE. Mean age was 48.0 (standard deviation [SD] 15.7) years and 88% were female. Over a median follow-up period of 4.3 (interquartile range [IQR] 1.9–7.0) years, 59% (315/533) had evidence of post-SLE diagnosis incident organ damage (≥ 1 type), which was greatest for musculoskeletal (146/819 [18%]), cardiovascular (149/842 [18%]), and skin (148/856 [17%]) domains. Patients with organ damage had greater resource use for all organ systems, excluding gonadal, versus those without it. Overall, mean (SD) annualized all-cause HCRU was greater in patients with organ damage versus those without it (inpatient, 1.0 versus 0.2; outpatient, 7.3 versus 3.5; accident and emergency, 0.5 versus 0.2 days; primary care contacts, 28.7 versus 16.5; prescription medications, 62.3 versus 22.9). Adjusted mean annualized all-cause costs were significantly greater in both post- and pre-organ damage index periods for patients with organ damage versus those without it (all P

Abstract Introduction This analysis was conducted to assess the incidence of adverse clinical outcomes, healthcare resource use (HCRU), and the costs associated with systemic corticosteroid (SCS) use in adults with systemic lupus erythematosus (SLE) in the UK. Methods We identified incident SLE cases using the Clinical Practice Research Datalink GOLD, Hospital Episode Statistics-linked healthcare, and Office for National Statistics mortality databases from January 1, 2005, to June 30, 2019. Adverse clinical outcomes, HCRU, and costs were captured for patients with and without prescribed SCS. Results Of 715 patients, 301 (42%) had initiated SCS use (mean [standard deviation (SD)] 3.2 [6.0] mg/day) and 414 (58%) had no recorded SCS use post-SLE diagnosis. Cumulative incidence of any adverse clinical outcome over 10-year follow-up was 50% (SCS group) and 22% (non-SCS group), with osteoporosis diagnosis/fracture most frequently reported. SCS exposure in the past 90 days was associated with an adjusted hazard ratio of 2.41 (95% confidence interval 1.77–3.26) for any adverse clinical outcome, with increased hazard for osteoporosis diagnosis/fracture (5.26, 3.61–7.65) and myocardial infarction (4.52, 1.16–17.71). Compared to low-dose SCS (
