Anti-Sp4 and Anti-CCAR1 autoantibodies in UK vs. US patients with adult and juvenile-onset anti-TIF1ƴ-positive myositis.

Anti-TIF1γ autoantibodies are associated with malignancy in adult-onset idiopathic inflammatory myopathy (IIM) and this risk is attenuated if patients are also positive for anti-specificity protein 4 (Sp4) or anti-cell division cycle apoptosis regulator protein 1 (CCAR1). In anti-TIF1γ positive US dermatomyositis (DM) patients, anti-Sp4 and anti-CCAR1 autoantibody frequencies are reported as 32% and 43% in adults and 9% and 19% in juveniles, respectively. This study aims to identify the frequency of anti-Sp4 and anti-CCAR1 in adult and juvenile UK anti-TIF1ƴ-positive myositis populations and report clinical associations. Serum samples from 51 UK participants with adult-onset IIM and 55 UK participants with JDM, all anti-TIF1γ autoantibody positive, and 24 healthy control samples were screened for anti-Sp4 and anti-CCAR1 autoantibodies by ELISA. In UK adult anti-TIF1γ positive IIM patients, anti-Sp4 and anti-CCAR1 frequencies were 4% (2/51) and 16% (8/51). Both adult patients with anti-Sp4 were also positive for anti-CCAR1. In UK juveniles, anti-Sp4 was not detected and 16% (7/55) had anti-CCAR1 autoantibodies. Nineteen (37%) anti-TIF1γ positive UK adult myositis patients had cancer; neither of the two patients with anti-Sp4 autoantibodies and 25% (2/8) of anti-CCAR1 autoantibody-positive patients had cancer. No anti-Sp4 or anti-CCAR1 clinical associations were identified. Anti-Sp4 and anti-CCAR1 autoantibodies are less common in the adult UK anti-TIF1ƴ-positive myositis population compared with published US data, limiting their use as biomarkers for cancer risk. In patients with juvenile onset disease, anti-Sp4 is less frequent in UK patients compared with the US, but the prevalence of anti-CCAR1 autoantibodies is similar.

P079 HOME BLOOD PRESSURE SCREENING IN MAY MEASUREMENT MONTH 2022 USING THE ZOE HEALTH STUDY APP

Background and Objective: May Measurement Month (MMM) is a global blood pressure (BP) screening campaign with aims to raise awareness of raised BP. In 2022, MMM incorporated home BP measurements from UK users of the ZOE Health Study app. We compare rates of hypertension prevalence, treatment, and control amongst ZOE app users with other European non-ZOE MMM participants. Methods: Adult (≥18 years) UK ZOE app users were invited to participate in MMM in 2022. ZOE participants were advised on taking three home BP measurements and non-ZOE participants had three standardised seated BP measurements in a range of facilities outside the home. All participants completed a questionnaire including demographics and antihypertensive medication use. Hypertension was defined using thresholds for clinic BP (≥140/90 mmHg) for non-ZOE participants and thresholds for home BP (≥135/85 mmHg) for ZOE participants, based on the mean of the second and third measurements, and/or taking antihypertensive medication. Awareness was defined as having a previous diagnosis of hypertension or treatment with antihypertensive medication. Results: A total of 50,200 ZOE participants were screened in MMM22, of whom 94.0% were over 50 years of age and 65.8% were female. 24,967 (49.7%) were hypertensive, of whom 19,356 (77.5%) were aware, and 18,195 (72.9%) were taking antihypertensive medication, and 11,454 (45.9%) were controlled to <135/85 mmHg. Compared to the other 64,256 MMM22 European participants (mean age 53.6 [SD 16.8] years, 58.7% female), ZOE participants had slightly higher rates of hypertension (49.7% vs 48.9%), and greater proportions of ZOE hypertensive participants were aware (77.5% vs 70.8%), treated (72.9% vs 63.3%), and controlled to <135/85 in ZOE participants and <140/90 mmHg in non-ZOE participants (45.9% vs 30.9%) (p<0.001 for all). Conclusions: In this large UK sample of ZOE users with hypertension, a higher proportion were aware, treated and controlled than amongst other European MMM screenees with hypertension. These digitally-enabled ZOE users apparently have greater access or engagement with effective BP management strategies.

Are protected characteristics associated with mental health care inequalities in the adult UK general population? a cross-sectional study.

This study investigates the association between protected characteristics and inequalities in mental health care in the UK. Multinomial regression was used to model the association between protected characteristics and self-reported distress. Data was extracted from waves 6-10 (2014-2019) of the UK Household Longitudinal Study. Two risk categories were constructed: "undiagnosed distress" referred to a General Health Questionnaire-12 (GHQ-12) score above "caseness" along with no history of mental health diagnosis; "diagnosis without self-report symptoms" referred to a GHQ-12 score consistently below "caseness" within the study time frame but having received a mental health diagnosis. Compared to people without a disability, people with a disability are at considerably greater risk of both undiagnosed distress (Relative risk ratios (RRR) 2.76; Confidence Interval (CI): 2.55, 2.99) and diagnosis without self-reported symptoms (RRR 3.61; CI: 2.80, 4.66). Likewise, women were more likely than men to report undiagnosed distress (RRR = 1.49; CI: 1.38,1.61) or a diagnosis without self-reported symptoms (RRR = 1.38; CI: 1.08, 1.76. Lesbian, gay, and bisexual people are at greater risk of undiagnosed distress compared with heterosexual people (RRR 1.42; CI: 1.19, 1.70). Adults aged 16-24 years were at greatest risk compared to all other age groups. People from a minority ethnic background had a reduced risk of diagnosis without self-report symptoms compared with people from a White ethnic background (RRR 0.34; CI: 0.20, 0.61). Education, employment and income variables moderated some of these associations. This is the first study to examine diagnosis without self-report symptoms alongside undiagnosed distress. Findings suggest that addressing inequality in mental health care requires increased understanding of the needs and strengths within different groups and to provide appropriate forms of social, medical or psychosocial intervention rather than a singular focus on increasing detection, diagnosis and treatment. People with a disability appear to be at greatest disadvantage, requiring greater attention in policy and practice.

Can Machine Learning Assist in Diagnosis of Primary Immune Thrombocytopenia? A Feasibility Study.

Primary Immune Thrombocytopenia (ITP) is a rare autoimmune disease characterised by the immune-mediated destruction of peripheral blood platelets in patients leading to low platelet counts and bleeding. The diagnosis and effective management of ITP are challenging because there is no established test to confirm the disease and no biomarker with which one can predict the response to treatment and outcome. In this work, we conduct a feasibility study to check if machine learning can be applied effectively for the diagnosis of ITP using routine blood tests and demographic data in a non-acute outpatient setting. Various ML models, including Logistic Regression, Support Vector Machine, k-Nearest Neighbor, Decision Tree and Random Forest, were applied to data from the UK Adult ITP Registry and a general haematology clinic. Two different approaches were investigated: a demographic-unaware and a demographic-aware one. We conduct extensive experiments to evaluate the predictive performance of these models and approaches, as well as their bias. The results revealed that Decision Tree and Random Forest models were both superior and fair, achieving nearly perfect predictive and fairness scores, with platelet count identified as the most significant variable. Models not provided with demographic information performed better in terms of predictive accuracy but showed lower fairness scores, illustrating a trade-off between predictive performance and fairness.

Can environmental traffic light warning labels reduce meat meal selection? A randomised experimental study with UK meat consumers

An important area for tackling climate change and health improvement is reducing population meat consumption. Traffic light labelling has successfully been implemented to reduce the consumption of unhealthy foods and sugary drinks. The present research extends this work to meat selection. We tested 1,300 adult UK meat consumers (with quotas for age and gender to approximate a nationally representative sample). Participants were randomised into one of four experimental groups: (1) a red traffic light label with the text ‘High Climate Impact’ displayed on meat meal options only; (2) a green traffic light label with the text ‘Low Climate Impact’ displayed on vegetarian and vegan meal options only; (3) red/orange/green (ROG) traffic light labels displayed on relevant meals; and (4) control (no label present). Participants made meal selections within their randomised group across 20 meal trials. A beta-regression was performed to ascertain the change in primary outcome (proportion of meat meals selected across the 20 trials) across the different groups. The red-only label and ROG labels significantly reduced the proportion of meat meals selected compared to the unlabelled control group, by 9.2% and 9.8% respectively. The green-only label did not differ from control. Negatively framed traffic light labels seem to be effective at discouraging meat selection. The labels appeared to be moderately acceptable to meat eaters, who did not think the labels impacted the appeal of the products. These encouraging findings require replication in real-life settings.

No evidence for a causal contribution of bioavailable testosterone to ADHD in sex-combined and sex-specific two-sample Mendelian randomization studies.

The higher prevalence of attention-deficit/hyperactivity disorder (ADHD) in males raises the question of whether testosterone is implicated in ADHD risk. However, cross-sectional studies did not identify an association between ADHD and testosterone levels. Mendelian randomization (MR) studies can overcome limitations inherent to association studies, especially of reverse causation and residual confounding. In the current study, sex-combined and sex-specific two-sample MR analyses were conducted to address whether testosterone has a causal influence on ADHD risk. Sex-combined as well as sex-specific target-genetic variants for bioavailable testosterone were derived from a large genome-wide association study (GWAS) on up to 382,988 adult white European UK Biobank study participants. In our sex-specific analyses for ADHD, including data from 14,154 males and 4,945 females with ADHD (17,948 and 16,246 controls respectively), no association between bioavailable testosterone and ADHD risk was found, neither in males (inverse-variance weighted (IVW): beta = 0.09, 95%-CI [-0.10, 0.27]) nor in females (IVW: beta=-0.01, 95%-CI [-0.20, 0.19]). However, in the sex-combined analysis, including 38,691 cases and 186,843 controls, genetically predicted bioavailable testosterone was associated with ADHD risk (IVW: beta = 0.24, 95%-CI [0.09, 0.39]). The inclusion of birth weight and/or SHBG as additional variables in multivariable MR analyses did not alter this result. However, when correcting for potential BMI-driven pleiotropy by a multivariable MR study, all effect estimates for testosterone showed non-significant results. Taken together, no robust evidence for a causal effect of bioavailable testosterone on the risk for ADHD was found.

A Model for Consumer Acceptance of Insect-Based Dog Foods among Adult UK Dog Owners.

The use of alternative proteins is becoming more common in pet feed, and insect-based dog foods (IBDFs) are becoming more widely available. However, little research has been conducted to date in respect of the drivers for consumers' acceptance of IBDF. This study aimed to investigate the acceptance of IBDF among adult UK dog owners and the factors influencing the decision to try and buy such products. A theoretical model was developed following a review of the existing literature. An online survey of 280 participants was carried out and the results were analysed using structural equation modelling (SEM) to test the theoretical model. The following constructs all had a significant impact on attitudes towards IBDF and/or intentions to try and buy IBDF: food preferences for animal welfare, health and environment; attitudes towards uses of animals; beliefs about insect sentience; disgust; perceptions of benefits and risks; and social norms. Social norms had the strongest influence of any single construct. Consumer acceptance of IBDF is multi-faceted including social, cultural and ethical components, and it is likely that the better availability of information and opportunities for consumers to familiarise themselves with IBDF would help to drive consumer acceptance. In order to allow dog owners to make informed decisions in line with their ethical preferences, further research is needed to establish the overall health and welfare implications of IBDF on the animals involved in production, as well as the companion animals, who are the ultimate consumers.

GripAble: Interrater reliability and normative grip strength of UK population

BackgroundHand grip strength is an established indicator of individual health status and is used as a biomarker for predicting mortality, disability, and disease risks. GripAble hand grip dynamometer offers a modernized approach to measuring grip strength with its digital and high-accuracy measurement system. PurposeThis study aimed to (1) assess the interrater reliability of maximum grip strength (MGS) measurement and (2) establish GripAble’s own gender-, age group- and hand-stratified normative MGS reference values of the adult UK population. Study DesignCross-sectional study design. MethodsInterrater reliability among three raters assessing 30 participants across diverse age groups was measured using the intraclass correlation. In the second study, 11 investigators gathered MGS data from 907 participants across diverse age groups and gender. The average, standard deviation, minimum, median, maximum, and percentiles of MGS were computed for each gender, age group, and hand (L/R). The relationship between MGS and age was examined using quantile regression analysis. Additionally, generalized linear model regression analysis was conducted to explore the influence of participants' demographics (gender, hand [L/R], hand length, hand circumference, age, weight, and height) on MGS. ResultsMGS measurements between raters showed excellent agreement (ICC(2,1) = 0.991, 95% confidence interval [0.98, 1.0]). The MGS and age relationship follows a curvilinear pattern, reaching a peak median MGS values of up to 20 kg between 30 and 49 years for females and up to 35 kg between 30 and 59 years for males. Subsequently, MGS declined as age advanced. Gender and hand (L/R) emerged as the primary factors influencing MGS, followed by hand length, hand circumference, age, weight, and height. ConclusionsThe presented normative MGS reference values can be used for interpreting MGS measurements obtained from adults in the United Kingdom using GripAble. This study, along with previous studies on GripAble devices, confirms GripAble as a reliable and valid tool for measuring MGS.

The adult ADHD assessment quality assurance standard.

Attention Deficit Hyperactivity Disorder (ADHD) frequently persists into adulthood. There are practice guidelines that outline the requirements for the assessment and treatment of adults. Nevertheless, guidelines specifying what constitutes a good quality diagnostic assessment and report and the competencies required to be a specialist assessor are lacking. This can lead to variation in the quality and reliability of adult ADHD assessments. Poor quality assessments may not be accepted as valid indicators of the presence of ADHD by other clinicians or services, resulting in wasteful re-assessments and delays in providing treatment. To address this issue the UK Adult ADHD Network (UKAAN) proposes a quality framework for adult ADHD assessments - the Adult ADHD Assessment Quality Assurance Standard (AQAS). The co-authors agreed on five questions or themes that then guided the development of a set of consensus statements. An initial draft was reviewed and amended in an iterative process to reach a final consensus. What constitutes a high-quality diagnostic assessment and report was agreed by consensus of the co-authors. The resulting guideline emphasises the need to evaluate impairment, describes core competencies required by the assessor and highlights the importance of linking the diagnosis to an appropriate post-diagnostic discussion. Assessments should be completed in the context of a full psychiatric and neurodevelopmental review, and need good interview skills, using a semi-structured interview with open questioning and probing to elicit real life examples of symptoms and impairments. It is recommended that 2 hours or more is required for an adequate assessment including both the diagnostic assessment and initial post-assessment discussions. The AQAS has been developed as a practical resource to support reliable and valid diagnostic assessments of adult ADHD. It is intended to complement formal training. A secondary objective is to empower patients by providing them with evidence-based information on what to expect from an assessment and assessment report.

Understanding UK public views on normative decisions made to value health-related quality of life in children: A qualitative study

Developing methodology for measuring and valuing child health-related quality of life (HRQoL) is a priority for health technology agencies. One aspect of this is normative decisions that are made in child HRQoL valuation. This qualitative study aimed to better understand adult public opinion on the normative questions of whose preferences to elicit (adults, children, or both) and from which perspective (who should be imagined living in impaired health), when valuing child HRQoL. Opinions of the adult UK public (N = 32) were solicited using online semi-structured focus groups, featuring a breadth of age, sex, ethnicities, and responsibility for children under 18 years. Participants were provided with bespoke informational material on health state valuation and were probed for their views. Arguments for and against different positions were discussed. Data was analysed using framework analysis. Participants demonstrated near-to-universal agreement that children should be involved in valuation in some form, yet this should differ depending on age or maturity. There was strong support for approaches combining involvement from children and adults (e.g., their parents), especially for younger children. There was little intuitive support for the ‘taxpayer argument’ for asking taxpaying adults. In the context of greater involvement of children in valuation, most participants supported using an ‘own’ perspective. Most participants thought that valuation study participants should know the exercise is about valuing child health states for ethical reasons. Informed views from the UK public on who should be asked and with what perspective when valuing child HRQoL appear to differ from normative positions previously advocated by some health economists, such as prioritising the preferences of taxpaying adults. In contrast, the results suggest including adults and children in valuation, with the proviso that the children are of an appropriate age and level of maturity, and that an own perspective is used wherever possible.

Adult Cerebral Malaria: Acute and Subacute Imaging Findings, Long-term Clinical Consequences.

Cerebral malaria is an important cause of mortality and neurodisability in endemic regions. We show magnetic resonance imaging (MRI) features suggestive of cytotoxic and vasogenic cerebral edema followed by microhemorrhages in 2 adult UK cases, comparing them with an Indian cohort. Long-term follow-up images correlate ongoing changes with residual functional impairment.

Gym lifestyle factors and male reproductive health: a study into young adult usage and perceptions

Research questionWhat level of awareness do young adults have regarding the potential impacts of gym lifestyle factors and supplementation on male infertility? DesignBetween February and March 2023 a questionnaire (n = 153) was employed to gauge attitudes to and awareness of the effects of male reproductive health and gym lifestyles on male fertility. Two semi-structured focus groups (n = 10 total), stratified by sex assigned at birth, were conducted using a set of discussion topics. ResultsThe survey revealed a statistically significant difference between male and female awareness of the potential impacts of some forms of high-intensity exercise and protein supplementation on male reproductive health (P = 0.045). Many men do not think about fertility unprompted; the survey revealed that fewer men have thought about their fertility compared with those who are curious about their fertility (P = 4.7 × 10–5) and those who believe their personal fertility is important to them (P = 8.1 × 10–6). Men were more likely to make a change in their behaviour if it had a long-term compared with a short-term effect on their fertility (P < 10–5). Five focus group themes surrounding awareness of male reproductive health were extracted. ConclusionsThis work has shown that there is a significant lack of awareness and information surrounding the effects of gym lifestyles on male infertility in a young adult UK population. Crucially, levels of awareness differ significantly between men and women. Men have a potentially alarming lack of concern over their own fertility and how factors such as gym supplements can have negative long-term impacts.

Inequalities and mental health during the Coronavirus pandemic in the UK: a mixed-methods exploration

BackgroundThe World Health Organisation declared the novel Coronavirus disease (COVID-19) a global pandemic on 11th March 2020. Since then, the world has been firmly in its grip. At the time of writing, there were more than 767,972,961 million confirmed cases and over 6,950,655 million deaths. While the main policy focus has been on controlling the virus and ensuring vaccine roll-out and uptake, the population mental health impacts of the pandemic are expected to be long-term, with certain population groups affected more than others.MethodsThe overall objectives of our ‘Coronavirus: Mental Health and the Pandemic’ study were to explore UK adults’ experiences of the Coronavirus pandemic and to gain insights into the mental health impacts, population-level changes over time, current and future mental health needs, and how these can best be addressed. The wider mixed-methods study consisted of repeated cross-sectional surveys and embedded qualitative sub-studies including in-depth interviews and focus group discussions with the wider UK adult population. For this particular inequalities and mental health sub-study, we used mixed methods data from our cross-sectional surveys and we carried out three Focus Group Discussions with a maximum variation sample from across the UK adult population. The discussions covered the broader topic of 'Inequalities and mental health during the Coronavirus pandemic in the UK’ and took place online between April and August 2020. Focus Groups transcripts were analysed using thematic analysis in NVIVO. Cross-sectional survey data were analysed using STATA for descriptive statistics.ResultsThree broad main themes emerged, each supporting a number of sub-themes: (1) Impacts of the pandemic; (2) Moving forward: needs and recommendations; (3) Coping mechanisms and resilience. Findings showed that participants described their experiences of the pandemic in relation to its impact on themselves and on different groups of people. Their experiences illustrated how the pandemic and subsequent measures had exacerbated existing inequalities and created new ones, and triggered various emotional responses. Participants also described their coping strategies and what worked and did not work for them, as well as support needs and recommendations for moving forward through, and out of, the pandemic; all of which are valuable learnings to be considered in policy making for improving mental health and for ensuring future preparedness.ConclusionsThe pandemic is taking a long-term toll on the nations’ mental health which will continue to have impacts for years to come. It is therefore crucial to learn the vital lessons learned from this pandemic. Specific as well as whole-government policies need to respond to this, address inequalities and the different needs across the life-course and across society, and take a holistic approach to mental health improvement across the UK.

The relationship between weight-related indicators and depressive symptoms during adolescence and adulthood: results from two twin studies.

The association between weight and depressive symptoms is well established, but the direction of effects remains unclear. Most studies rely on body mass index (BMI) as the sole weight indicator, with few examining the aetiology of the association between weight indicators and depressive symptoms. We analysed data from the Twins Early Development Study (TEDS) and UK Adult Twin Registry (TwinsUK) (7658 and 2775 twin pairs, respectively). A phenotypic cross-lagged panel model assessed the directionality between BMI and depressive symptoms at ages 12, 16, and 21 years in TEDS. Bivariate correlations tested the phenotypic association between a range of weight indicators and depressive symptoms in TwinsUK. In both samples, structural equation modelling of twin data investigated genetic and environmental influences between weight indicators and depression. Sensitivity analyses included two-wave phenotypic cross-lagged panel models and the exclusion of those with a BMI <18.5. Within TEDS, the relationship between BMI and depression was bidirectional between ages 12 and 16 with a stronger influence of earlier BMI on later depression. The associations were unidirectional thereafter with depression at 16 influencing BMI at 21. Small genetic correlations were found between BMI and depression at ages 16 and 21, but not at 12. Within TwinsUK, depression was weakly correlated with weight indicators; therefore, it was not possible to generate precise estimates of genetic or environmental correlations. The directionality of the relationship between BMI and depression appears to be developmentally sensitive. Further research with larger genetically informative samples is needed to estimate the aetiological influence on these associations.

Mental Health and Recreational Angling in UK Adult Males: A Cross-Sectional Study.

Exposure to aquatic environments (i.e., blue spaces) can lead to improved mental health and well-being. One meaningful way to spend time in blue spaces is through recreational angling, although limited scientific literature exists on this topic. The present study aims to examine the relationship between recreational angling and mental health and well-being in a sample of UK adult male anglers. A cross-sectional online survey asked questions about demographic characteristics, participation in recreational angling, physical activity levels, diagnosis of psychiatric disorders, and mental health and well-being. Relationships between angling status (i.e., how often and how long participants angled for) and mental health variables were determined using regression models adjusted for age. In total, 1752 participants completed the survey. The regression models found that those who took part in angling more regularly had reduced odds of having depression (p < 0.001), schizophrenia (p = 0.001), suicidal thoughts (p < 0.001), and deliberately self-harming (p = 0.012), in addition to having a higher mental well-being and lower symptoms of depression and anxiety compared to those taking part in angling less frequently. In general, the findings suggest that encouraging frequent participation in recreational angling could be a dual method strategy for promoting relaxation and positive mental health, as well as encouraging increased levels of physical activity in those with mental health issues.

P372 “The outcome would not have been the same” - multidisciplinary team experience of the role of occupational therapy in a Cystic Fibrosis unit

Occupational Therapy (OT) provides practical support to enable people to overcome barriers to meaningful occupation. People with cystic fibrosis (pwCF) have numerous challenges in their daily lives, but historically OT has not been embedded within conventional CF multidisciplinary teams (MDT). A one year OT role was created within a large UK Adult MDT.

P291 Screening for Coeliac Disease in adults with cystic fibrosis in Wales

Emerging evidence suggests an increased prevalence of Coeliac Disease (CD) in People with Cystic Fibrosis (PwCF) when compared to the UK population. The objective was to screen the patients of the All Wales Adult Cystic Fibrosis Centre (AWACFC) for CD and compare the results to the prevalence of CD within the adult UK general population, which is estimated to be 1 in 100.

A retrospective analysis of the ethnicity of individuals referred to a tertiary neuropsychology service in the United Kingdom

Objective: Ethnic minorities comprise approximately 18% of the UK population and are at high risk of developing neurological conditions. Despite this, there is little information regarding their access to neuropsychology services. This study evaluated whether ethnic minorities were proportionally represented in a tertiary neuropsychology department in the UK in accordance with census data for the region. We also aimed to highlight which ethnic groups were over- and underrepresented. Method: Anonymised demographic data of 3429 outpatient and 3304 inpatient referrals to an adult UK neuropsychology department was collected. These data were compared to the 2021 UK census data for the region. Results: Ethnicities in both the outpatient referrals (χ2(15) = 24066.55, p < .001) and inpatient referrals (χ2(15) = 35940924.75, p < .001) are significantly different from the Census. All ethnic minorities were underrepresented in adult neuropsychology referral data for both outpatient settings (−0.06% to −4.66%) and inpatient settings (−0.01% to −4.99%). Pakistani individuals were the most underrepresented across all settings, followed by individuals from an African background. Conversely, individuals of White British ethnicity were overrepresented in both outpatient settings (+10.73%) and inpatient settings (+15.68%). Conclusions: The UK ethnic minorities were not referred to a neuropsychology service relative to regional population prevalence. This contradicts their increased susceptibility for risk of neurological conditions but may also indicate the inaccessibility of neuroscience services for ethnic minorities. Replicating this study across different regions and gathering data on prevalence rates for different neurological conditions across ethnicity is recommended. Additionally, improving accessibility of neuropsychology services for British ethnic minorities should be prioritised.

Association Between Combat-Related Traumatic Injury and Skeletal Health: Bone Mineral Density Loss Is Localized and Correlates With Altered Loading in Amputees: the Armed Services Trauma Rehabilitation Outcome (ADVANCE) Study.

The association between combat-related traumatic injury (CRTI) and bone health is uncertain. A disproportionate number of lower limb amputees from the Iraq and Afghanistan conflicts are diagnosed with osteopenia/osteoporosis, increasing lifetime risk of fragility fracture and challenging traditional osteoporosis treatment paradigms. The aim of this study is to test the hypotheses that CRTI results in a systemic reduction in bone mineral density (BMD) and that active traumatic lower limb amputees have localized BMD reduction, which is more prominent with higher level amputations. This is a cross-sectional analysis of the first phase of a cohort study comprising 575 male adult UK military personnel with CRTI (UK-Afghanistan War 2003 to 2014; including 153 lower limb amputees) who were frequency-matched to 562 uninjured men by age, service, rank, regiment, deployment period, and role-in-theatre. BMD was assessed using dual-energy X-ray absorptiometry (DXA) scanning of the hips and lumbar spine. Femoral neck BMD was lower in the CRTI than the uninjured group (T-score -0.08 versus -0.42 p=.000). Subgroup analysis revealed this reduction was significant only at the femoral neck of the amputated limb of amputees (p=0.000), where the reduction was greater for above knee amputees than below knee amputees (p < 0.001). There were no differences in spine BMD or activity levels between amputees and controls. Changes in bone health in CRTI appear to be mechanically driven rather than systemic and are only evident in those with lower limb amputation. This may arise from altered joint and muscle loading creating a reduced mechanical stimulus to the femur resulting in localized unloading osteopenia. This suggests that interventions to stimulate bone may provide an effective management strategy. © 2023 Crown copyright and The Authors.

Prevalence and treatment patterns of adult atopic dermatitis in the UK Clinical Practice Research Datalink.

The prevalence of active atopic dermatitis (AD) in adults in the UK according to disease severity shows variability. This study evaluated disease prevalence and treatment patterns among the adult UK population with AD. Data were obtained from the Clinical Practice Research Datalink (CPRD) database. Adults with active AD were identified by an AD-related prescription or general practitioner visit within the same calendar year. Prevalence was defined as the number of patients with active AD on 1 January of each year as a percentage of the number of adults in the CPRD population on that date. Moderate-to-severe disease was classified as either referral to a specialist or prescription(s) for topical calcineurin inhibitors, phototherapy, or systemic treatment. Patient characteristics and treatment and referral patterns were analysed for patients with active AD in 2019. The overall prevalence of AD was stable at 2.4% per year during the period 2015-2019. In 2019, mean patient age (± standard deviation) was 52.6±21.0years, 58.2% of patients were female and mean disease duration was 9.4±5.9years. The most prescribed treatment was topical corticosteroids, in 78.5% of patients. 36.7% of patients with moderate-to-severe AD were prescribed systemic agents and 59.8% (vs. 32.3% of patients with mild AD) were referred to any secondary care or specialist treatment. The prevalence of active AD in the adult UK population was stable over the 5-year period (2015-2019) and was comparable to estimates from similar studies based on UK primary healthcare records.
