SLCO1B1*5 is protective against non-senile cataracts in cohort prescribed statins: analysis in a British-South Asian cohort

Abstract Background Reported association between statin use and cataract risk is controversial. The SLCO1B1 gene encodes a transport protein responsible for statin clearance. The SLCO1B1*5 reduced function variant is known to increase systemic exposure to statins. The aim of this study was to investigate a possible association between the SLCO1B1*5 reduced function variant and cataract risk in statin users of South Asian ethnicity. Methods The Genes & Health cohort consists of UK participants of Bangladeshi and Pakistani ancestry. SLCO1B1*5 genotype was assessed with the Illumina GSAMD-24v3-0-EA chip. Medication data from primary care health record linkage was used to compare those who had regularly used statins compared to those who had not. Multivariable logistic regression was used to test for association between statin use and cataracts, adjusting for population characteristics and potential confounders in 36,513 participants. Multivariable logistic regression was used to test association between SLCO1B1*5 heterozygotes or homozygotes and cataracts, in subgroups having been regularly prescribed statins versus not. Results Statins were prescribed to 35% (12,704) of participants (average age 41 years old, 45% male). Non-senile cataract was diagnosed in 5% (1686) of participants. An apparent association between statins and non-senile cataract (12% in statin users and 0.8% in non-statin users) was negated by inclusion of confounders. In those prescribed a statin, presence of the SLCO1B1*5 genotype was independently associated with a decreased risk of non-senile cataract (OR 0.7 (CI 0.5-0.9, p 0.007)). Conclusions Our findings suggest that there is no independent association between statin use and non-senile cataract risk after adjusting for confounders. Among statin users, the SLCO1B1*5 genotype is associated with a 30% risk reduction of non-senile cataracts. Stratification of on-drug cohorts by validated pharmacogenomic variants is a useful tool to support or repudiate adverse drug events in observational cohorts.Study results overview

Cardiovascular disease screening in homeless individuals-a feasibility study

Abstract Background The risk and burden of cardiovascular disease (CVD) are higher in homeless than in housed individuals, yet population-level CVD screening largely excludes homeless individuals. Purpose (i)To investigate feasibility of dedicated mobile CVD screening for homeless individuals; and (ii)To estimate prevalence of risk factors and burden of CVD Methods With patients, health professionals and researchers, we co-developed and implemented a 15-minute CVD assessment for homeless individuals as an add-on service to the Find&Treat service (a peer-led, multi-disciplinary outreach team across London) during scheduled, routine visits to homeless hostels. We included a questionnaire (demographic, past medical history and symptom data) as well as clinical assessment (blood pressure, ABPI, cholesterol, HDL, HDL ratio, glucose, HbA1c and mobile ECG to detect atrial fibrillation, AF). Results Among 656 individuals screened in 75 routine visits between May 2019 and January 2023, we recruited 524 (79.9%) individuals. Mean age was 47 (SD 13.1) years (range 18-87). Male gender (79%) and white ethnicity (55%) were more common. Current or previous smoking (79%), previous CVD (stroke, myocardial infarction, or peripheral arterial disease) (15%) and family history of heart attack in a 1st degree relative<60 years (27%) were common. Although only 2% reported previously diagnosed hypercholesterolaemia, 24% of screened individuals had total cholesterol>5.0 mmol/L. Prevalence of AF was high, particularly among those aged 18-30 (7/57, 12.3%). Asian and British Asian individuals had highest prevalence of raised HbA1C levels (>6%) (8/33, 24.2%), compared to black and black British (22/120, 18.3%) and white (15/283, 5.3%) individuals. Among individuals aged 25 – 84 with no previous CVD, one third had a 10-year QRISK score of ≥10% (120/362, 33.1%), consistent across different ethnic groups: white (75/233, 32.2%), black (24/77, 31.2%) and Asian (6/17, 35.3%). Conclusions A simple, pragmatic CVD assessment for homeless individuals was feasible and acceptable, and identified gaps in diagnosis and prevention. There is a high burden of CVD risk factors and CVD amongst homeless individuals, which could be addressed by integration of CVD screening into existing inclusion health outreach frameworks.

British South Asian ancestry participants views of pharmacogenomics clinical implementation and research: a thematic analysis

BackgroundSouth Asian ancestry populations are underrepresented in genomic studies and therapeutics trials. British South Asians suffer from multi-morbidity leading to polypharmacy. Our objective was to elucidate British South Asian ancestry community perspectives on pharmacogenomic implementation and sharing pharmacogenomic clinical data for research.MethodsFour focus groups were conducted (9–12 participants in each). Two groups were mixed gender, while one group was male only and one was female only. Simultaneous interpretation was available to participants in Urdu and Bengali. Focus groups were recorded and abridged transcription and thematic analysis were undertaken.ResultsThere were 42 participants, 64% female. 26% were born in the UK or Europe. 52% were born in Bangladesh and 17% in Pakistan. 36% reported university level education.Implementation of pharmacogenomics was perceived to be beneficial to individuals but pose a risk of overburdening resource limited systems. Pharmacogenomic research was perceived to be beneficial to the community, with concerns about data privacy and misuse. Data sharing was desirable if the researchers did not have a financial stake, and benefits would be shared.Trust was the key condition for the acceptability of both clinical implementation and research. Trust was linked with medication compliance. Education, outreach, and communication facilitate trust.Conclusions (Significance and Impact of the Study)Pharmacogenomics implementation with appropriate education and communication has the potential to enhance trust and contribute to increased medication compliance. Trust drives data sharing, which would enable enhanced representation in research. Representation in scientific evidence base could cyclically enhance trust and compliance.

Public health qualifications, motivation, and experience of pharmacy professionals: exploratory cross-sectional surveys of pharmacy and public health professionals

BackgroundPharmacy professionals (pharmacists and pharmacy technicians; PPs) are recognised for delivering public health interventions (micro level). There is increased policy focus on population health management, but limited knowledge regarding the role of PPs within UK's public health meso and macro levels. This study aimed to explore UK PPs’ public health qualifications, specialisations, and motivations and barriers to pursuing advanced public health practice. MethodsIn this cross-sectional study, we developed and piloted two surveys, and we disseminated them separately via email to UK pharmacy and public health networks and social media, between June 19, and Oct 26, 2021. PPs with an interest or experience in public or population health were invited to participate in the study. We asked PPs questions about public health qualifications, specialisations, motivations, and barriers, and we also asked PHPs for opinions regarding the value of specialist public health skills for PPs. Numerical data were summarised, and responses collated into themes. NHS Health Research Authority tool identified ethics approval not required; and the questionnaire included consent request. Findings128 PPs (85% pharmacists) and 54 PHPs responded. Of the PPs who responded, 90 (70%) were female and 35 (27%) were male; 62 (48%) were White British, 19 (14%) were Asian or Asian British, 14 (12%) were Black or Black British. They worked in primary care (34%, n=43), secondary care (26%, n=33), Community Pharmacy (13%, n=16), and public health bodies (13%, n=16). Overall, 34 (27%) of 128 PPs (32 pharmacists; 2 pharmacy technicians) possessed public health qualifications (MPH, PhD). Motivations for these qualifications were ambition to work as PP in public health PP (31%; 17/55 respondents), public health as alternative career (29%; 16/55), general interest (27%; 15/55) recommended or required for current role (11%; 6/55). Themes of barriers included limited training opportunities and poor career pathways. For the PHP survey, 36 (67%) of 54 were female and 16 (30%) were male. They worked as Consultants or Directors (28%, n=15), Registrars (24%, n=13), Practitioners (15%, n=8). 45 (87%) of 52 PHP respondents agreed that specialist PPs in public health would be beneficial to public health; 13 (45%) of 29 respondents recommended a public health Master's degree, eight (27%) recommended experience or postgraduate modules in health economics and health inequalities, three (10%) recommended credentialing for PPs to specialise. InterpretationFindings suggest responding PPs are motivated to advance in public health practice, despite barriers. Collaboration with PHPs and development of communities of practice might address barriers identified and contribute to advanced public health practice for PPs, supporting the increased focus on population health management in the UK. Limitations include the exploratory nature of the study, and the fact that PPs responding to public health surveys might be more motivated to advance in public health practice than those not responding.

International Legacies of a Century and a Half of the Case Method

Abstract Save the Constitution, the United States’s most famous legal export may well be the case method. This article pieces together the story of how CC Langdell’s brainchild was brought to the rest of the common law world in treading the momentous events and geopolitics of the last century and a half, and reflects on the lessons from this global experiment for the present and future of the case method. After initially attracting little attention overseas, the rise of the case method encountered its watershed in the post-war period. From then on, the method’s further expansion branched into two narratives: one in the Western world and the other in the former British African, Asian, and Caribbean colonies. The overseas experiments with the case method yielded some durable successes and cast a light on its singular ability to adapt to widely different environments. But mostly the picture is one of mixed results, especially outside the Western world, owing to a failure to devise an educational program adapted to the varying local circumstances. As with law itself, the teaching of law is inextricably tied to local idiosyncrasies and world politics, thus making the future of the case method as difficult to predict as it would have been for Langdell and his contemporaries. Today’s different national and international contexts from that of 1945 represent an opportunity to reassess the merits of the case method in our more mature legal and educational environments, freed from colonial and neocolonial agendas.

When does a book launch become a meeting?

This is an account of a discussion between Sita Balani, Amardeep Singh Dhillon, Gail Lewis and Adam Elliott-Cooper on Sita Balani's book, Deadly and Slick: Sexual Modernity and the Making of Race, offered as a means of sharing its insights and exchanges among a wider community of activists and organisers. The origin of the book was Sita's observation of two dynamics at play at the end of the 1990s and early 2000s. The first was the fracturing of British Asian identity in the early years of the 'War on Terror', as Muslim became a racialised category in and of itself. The second was the rapid rise in 'gay rights': until 2003, Section 28 had criminalised the teaching of homosexuality as a 'pretended family relationship'; in 2004, civil partnerships had been introduced. Sita recognised that the moving around of these categories of sexuality and race was not merely coincidental. To help understand this she has introduced the concept of 'sexual modernity', which also has two parts: the promise of self-realisation through the pursuit of romantic love, the nuclear family and sexual adventure, and then - what 'stalks' this possibility - all of the sexual conduct and sexual practice that is disavowed and excluded from this. The book charts the state's racial taxonomies alongside its mobilisation of categories of sexuality and gender, in both the historical colonial context and the contemporary imperial centre. Panellists discussed some of the contradictions of these developments. These included the inclusion of police officers in the Gay Pride parade; moral panics about - and violence against - asylum seekers and drag queens; the 'problem' of the Black boy being attributed to not-enough-patriarchy, while for South Asian Muslim women it is a question of too-much-patriarchy; in an historical context, sexual violence being the norm in Jamaica but a source of paranoia in the colony of India. Through showing us the field of battle and its character, Sita gives us a tool with which to help build aligned constituencies of opposition and vision

Strains of friendship: post-partition rāgadārī music publics in London

ABSTRACT How is cross-cultural communication around music in the British Asian diaspora shaped by the Partition of 1947? This article will discuss this question through a case study of the writings and relationships of four key South Asian music enthusiasts: one female patron of music, and three male scholar-researchers of music who befriended each other, and in the process redefined rāgadārī (classical) music publics in Britain, beginning in the 1970s and 80s. Through a discussion of their life-stories and narratives I reveal the importance of (i) storytelling and memory in the creation of diasporic homemaking, (ii) a gendered politics of musical commemoration, (iii) the anecdote as ‘musical gift’ (qua Sykes), and (iv) postcolonial cultural custodianship, in producing a unique rāgadārī musical public in London, across the Indo-Pak national border.

Diabetes mellitus and obesity among South Asians with ischemic stroke across three countries.

Diabetes mellitus and central obesity are more common among South Asian populations than among White British people. This study explores the differences in diabetes and obesity in South Asians with stroke living in the United Kingdom, India, and Qatar compared with White British stroke patients. The study included the UK, Indian, and Qatari arms of the ongoing large Bio-Repository of DNA in Stroke (BRAINS) international prospective hospital-based study for South Asian stroke. BRAINS includes 4580 South Asian and White British recruits from UK, Indian, and Qatar sites with first-ever ischemic stroke. The study population comprises 1751 White British (WB) UK residents, 1165 British South Asians (BSA), 1096 South Asians in India (ISA), and 568 South Asians in Qatar (QSA). ISA, BSA, and QSA South Asians suffered from higher prevalence of diabetes compared with WB by 14.5% (ISA: 95% confidence interval (CI) = 18.6-33.0, p < 0.001), 31.7% (BSA: 95% CI = 35.1-50.2, p < 0.001), and 32.7% (QSA: 95% CI = 28.1-37.3, p < 0.001), respectively. Although WB had the highest prevalence of body mass index (BMI) above 27 kg/m2 compared with South Asian patients (37% vs 21%, p < 0.001), South Asian patients had a higher waist circumference than WB (94.8 cm vs 90.8 cm, p < 0.001). Adjusting for traditional stroke risk factors, ISA, BSA, and QSA continued to display an increased risk of diabetes compared with WB by 3.28 (95% CI: 2.53-4.25, p < 0.001), 3.61 (95% CI: 2.90-4.51, p < 0.001), and 5.24 (95% CI: 3.93-7.00, p < 0.001), respectively. South Asian ischemic stroke patients living in Britain and Qatar have a near 3.5-fold risk of diabetes compared with White British stroke patients. Their body composition may partly help explain that increased risk. These findings have important implications for public health policymakers in nations with large South Asian populations.

P05 Osteoporosis in thalassemia; a case with multifactorial aetiology

Abstract Introduction Thalassemia patients are prone to osteoporosis due to multifactorial reasons, including anaemia, bone marrow expansion, iron overload and hypogonadism. Case description A 41-year-old British Asian male with beta thalassemia major was referred to rheumatology in 2018 for osteoporosis. In 2008, aged 27 years, whilst playing football, he developed a distal radial fracture and ulnar styloid process fracture and a DEXA scan had revealed low bone mineral density (BMD) for age. Subsequently, he was started on Ibandronic acid by his haematologist for a total of 10 years. After he was referred to rheumatology in 2018, bisphosphonates were discontinued as he had 5% improvement in BMD, a decade of bisphosphonates and no further fractures. Further assessment revealed multiple contributory factors for his osteoporosis. • Consistency low vitamin D – 9.6 nmol/L in 2009, average value of 20 • He was diagnosed with hypogonadism, poor compliance with IM testosterone injections • He had diabetes which was not optimally controlled • Evidence of iron overload with average serum ferritin of 2000 ug/L with deferasirox While these factors were optimised, it was decided to adopt a watch and wait policy with regards to specific osteoporosis treatment. Review in 2023 revealed serum testosterone level of 20.1 nmol/L (6.9-23.2) with better compliance with testosterone injections. Fructosamine levels were 310 (normal range 200-285) but it has reduced from a peak of 370. Serum ferritin levels have reduced to 776 down from a high of 5600. Normal vitamin D levels were maintained. The DEXA scan in 2023 revealed a spine T score of −2.4 which showed 10.2% increase in bone mineral density. DEXA scan in 2020 revealed T score of −3.1 in spine and −1.9 in hips. The P1NP level was 56 (19-69) which has reduced from 100 in 2021. Improvements in BMD and bone turnover markers were achieved through optimising contributory factors without any specific osteoporosis treatment. He will be monitored with periodic BMD and bone turnover markers. Discussion Anaemia and subsequent bone marrow expansion is a recognised cause for osteoporosis in thalassemia patients. While regular blood transfusions inhibit bone marrow expansion, ineffective erythropoiesis is not fully supressed. This patient received 3 units of blood every 4 weeks. Bone marrow expansion occurs mostly in trabecular bone resulting in low BMD is areas which generally have increased amount of trabecular bone such as the spine. Our patient had a lower BMD in the spine compared to the femoral neck. Iron overload directly disrupts bone formation and can result in endocrinopathies which contributes to osteoporosis. Hypogonadism is another well-recognised cause and is primarily results from iron deposition in pituitary and at times in the gonads. Hormonal replacement therapy reduces bone loss. Studies have shown that hypogonadic patients have more severe osteoporosis and predominant involvement of the femoral neck. Iron overload can cause diabetes mellitus and impaired growth hormone/ insulin growth factor-1 (IGF-1) axis which can contribute to osteoporosis. Our patient did have diabetes but had normal IGF-1 levels when checked previously. Deferoxamine which is one of iron chelating agents have been shown to reduce collagen synthesis and increases osteoblast apoptosis which might contribute to the development of osteoporosis. Vitamin D levels are well known to be low in patients with thalassemia compared to the general population. While there are no RCT’s to show that bisphosphonates reduce fracture risk, surrogate markers such as increased BMD and reduction in bone turnover markers are known to occur. Therefore, current guidance (Standards for the Clinical Care of Children and Adults with Thalassaemia in the UK) recommends bisphosphonates to be considered in patients with a low BMD for age (Z-score &amp;lt; −2.0, T-score &amp;lt; −2.5 if post-menopausal or over 50), if there are fragility fractures or falling BMD despite adequate vitamin D levels, and hormone supplementation. Key learning points Learning point Important to assess for osteoporosis in thalassaemic patients. There are multiple factors contributing to the development of osteoporosis which needs to be addressed together with endocrinologist and haematologist. Bisphosphonates are recommended though further RCT evidence is required to support this

Influence of autozygosity on common disease risk across the phenotypic spectrum

Autozygosity is associated with rare Mendelian disorders and clinically relevant quantitative traits. We investigated associations between the fraction of the genome in runs of homozygosity (FROH) and common diseases in Genes& Health (n= 23,978 British South Asians), UK Biobank (n= 397,184), and 23andMe. We show that restricting analysis to offspring of first cousins is an effective way of reducing confounding due to social/environmental correlates of FROH. Within this group in G&H+UK Biobank, we found experiment-wide significant associations between FROH and twelve common diseases. We replicated associations with type 2 diabetes (T2D) and post-traumatic stress disorder via within-sibling analysis in 23andMe (median n= 480,282). We estimated that autozygosity due to consanguinity accounts for 5%-18% of T2D cases among British Pakistanis. Our work highlights the possibility of widespread non-additive genetic effects on common diseases and has important implications for global populations with high rates of consanguinity.

Factor V Leiden, estrogen, and multimorbidity association with venous thromboembolism in a British-South Asian cohort

Multimorbidity, estrogen use, and Factor V Leiden (FVL) are known independent risk factors for venous thromboembolism (VTE). This cross-sectional analysis of women in the Genes& Health British-South Asian cohort (N 20,048) linked the F5 SNP rs6025 with estrogen prescribing data and VTE events. Multivariable logistic regression was used to test the association between estrogen use, FVL, common medical co-morbidities, and VTE. Estrogens were prescribed to 30% of women. 3% of participants were FVL carriers. 439 participants had a VTE event (2.2%), and VTE prevalence increased with obesity, hypertension, dyslipidemia, chronic kidney disease, estrogen use, and in the presence of FVL. One medical condition above wasindependently associated with VTE with an OR 1.6 (CI 1.2-2.0, p 0.001); two medical conditions OR 2.7 (CI 2.0-3.7, p<0.001); three OR 5.3 (CI 3.8-7.4, p<0.001); four OR 8.1 (CI 4.9-13.0, p<0.001). Multimorbidity and FVL compound risk of VTE with estrogen use.

Physical activity and TV viewing parenting practices for toddlers among South Asian and white families in the UK: born in Bradford 1000 study

BackgroundChildren of South Asian (SA) origin in the UK have lower levels of physical activity (PA), compared to their White counterparts. Parents play an important role in establishing PA habits among young children. The aim of this study was to compare PA and television (TV) viewing parenting practices for young children between SA British (SAB) and White British (WB) parents living in the UK.MethodsWe conducted a secondary analysis of the Born in Bradford (BiB) 1000 study, using survey data at child ages 24 and 36 months. The study sample included three groups of mothers (n = 1,149): foreign-born SAB (n = 458), UK-born SAB (n = 276), and WB (n = 455). Mothers completed a survey about parenting practices (i.e., PA supports, PA restrictions, TV viewing restrictions) at child age 24 months and child PA and TV viewing behaviors at child ages 24 and 36 months. Parenting practices were compared among the three groups. Multivariable linear regression analyses compared children’s weekly walking frequency and daily TV viewing hours by parenting practices in the three groups.ResultsThe foreign-born SAB group showed the lowest frequencies of PA-supportive parenting practices (verbal encouragement: 3.7 ± 3.1 times/week; logistic support: 1.5 ± 1.8 times/week) and the highest frequencies of PA-restrictive parenting practices (7.8 ± 7.7 times/week) among the three groups (p < 0.01). Children of Foreign-born SAB mothers had the most frequent TV watching during a mealtime (4.0 ± 3.1 times/week) among the three groups (p < 0.01). Less frequent PA-supportive parenting practices and SA ethnicity were associated with lower walking frequency at 24 and 36 months of age among children (p < 0.01). More frequent exposure to TV at mealtimes and SA ethnicity were associated with higher TV viewing time at 24 and 36 months of age among children (p < 0.01).ConclusionsThis study demonstrated that SAB parents, particularly those who are foreign-born, apply parenting practices for their young children that are less supportive of PA and more supportive of TV viewing, and their children have lower PA and higher TV viewing time, compared with their WB counterparts.

CYP2C19 Genotype Prevalence and Association With Recurrent Myocardial Infarction in British–South Asians Treated With Clopidogrel

BackgroundCytochrome P450 family 2 subfamily C member 19 (CYP2C19) is a hepatic enzyme involved in the metabolism of clopidogrel from a prodrug to its active metabolite. Prior studies of genetic polymorphisms in CYP2C19 and their relationship with clinical efficacy have not included South Asian populations. ObjectivesThe objective of this study was to assess prevalence of common CYP2C19 genotype polymorphisms in a British–South Asian population and correlate these with recurrent myocardial infarction risk in participants prescribed clopidogrel. MethodsThe Genes & Health cohort of British Bangladeshi and Pakistani ancestry participants were studied. CYP2C19 diplotypes were assessed using array data. Multivariable logistic regression was used to test for association between genetically inferred CYP2C19 metabolizer status and recurrent myocardial infarction, controlling for known cardiovascular disease risk factors, percutaneous coronary intervention, age, sex, and population stratification. ResultsGenes & Health cohort participants (N = 44,396) have a high prevalence (57%) of intermediate or poor CYP2C19 metabolizers, with at least 1 loss-of-function CYP2C19 allele. The prevalence of poor metabolizers carrying 2 CYP2C19 loss-of-function alleles is 13%, which is higher than that in previously studied European (2.4%) and Central/South Asian populations (8.2%). Sixty-nine percent of the cohort who were diagnosed with an acute myocardial infarction were prescribed clopidogrel. Poor metabolizers were significantly more likely to have a recurrent myocardial infarction (OR: 3.1; P = 0.019). ConclusionsA pharmacogenomic-driven approach to clopidogrel prescribing has the potential to impact significantly on clinical management and outcomes in individuals of Bangladeshi and Pakistani ancestry.

Partition at 75: reflections on migrant memories in the British South Asian diaspora

ABSTRACT In 2017, the 70th anniversary of the Partition of British India was widely discussed in the UK, not only within academic and cultural circles, but also in popular culture. Five years later, on the 75th anniversary of Partition, the scholarly, cultural and community interest in the events of 1947 intersected with the commemorations of the 50th anniversary of the expulsion of the South Asian population from Uganda, and the 70th anniversary of the Language Movement that led towards Bangladesh independence in 1971 - the 50th anniversary of which was celebrated just the year before. Based on the work of the Migrant Memory and the Postcolonial Imagination research project (Loughborough University) this article will explore the entanglement of the memories of these events within the South Asian diaspora, and how their transmission and communication shape the construction of contemporary diasporic identity and concepts of community, belonging and ‘home.’

CYP2C19 loss-of-function alleles are not associated with higher prevalence of gastrointestinal bleeds in those who have been prescribed antidepressants: Analysis in a British-South Asian cohort.

CYP2C19 is a hepatic enzyme involved in the metabolism of antidepressants associated with increased gastrointestinal bleed (GIB) risk. The aim of our study was to explore a possible association between loss-of-function CYP2C19 genotypes and GIB in South Asian ancestry participants prescribed antidepressants. Genes & Health participants with a record in Barts Health NHS Trust (N 22 753) were studied using a cross-sectional approach. CYP2C19 diplotypes were assessed and metabolizer type inferred from consortia guidance. Fisher's exact test was used to compare the prevalence of GIB in different metabolizer categories. Multivariable regression was used to test for association between antidepressant prescriptions and GIB, and between CYP2C19 metabolizer state and GIB in the subcohort prescribed antidepressants. Antidepressants were frequently prescribed (47%, N = 10 612). A total of 864 participants (4%) had a GIB; 534 (62%) had been prescribed a CYP2C19 metabolized antidepressant. There was an independent association between antidepressant prescriptions and GIB events (odds ratio 1.8, confidence interval 1.5-2.0, P < 0.0001). There was no relationship between CYP2C19 inferred poor (P 0.56) or intermediate (P 0.53) metabolizer status and GIB in those prescribed an antidepressant in unadjusted analysis. A multivariable logistic regression model did not show an independent association between poor (P 0.54) or intermediate (P 0.62) CYP2C19 metabolizers and GIB in the subcohort prescribed antidepressants. CYP2C19 dependent antidepressants are associated with increased GIB prevalence. GIB appeared independent from CYP2C19 metabolizer genotype in individuals who had been prescribed antidepressants. Precision dosing based on CYP2C19 genetic information alone is unlikely to reduce GIB prevalence.

A linear adjustment-based approach to posterior drift in transfer learning.

We present new models and methods for the posterior drift problem where the regression function in the target domain is modelled as a linear adjustment, on an appropriate scale, of that in the source domain, and study the theoretical properties of our proposed estimators in the binary classification problem. The core idea of our model inherits the simplicity and the usefulness of generalized linear models and accelerated failure time models from the classical statistics literature. Our approach is shown to be flexible and applicable in a variety of statistical settings, and can be adopted for transfer learning problems in various domains including epidemiology, genetics and biomedicine. As concrete applications, we illustrate the power of our approach (i) through mortality prediction for British Asians by borrowing strength from similar data from the larger pool of British Caucasians, using the UK Biobank data, and (ii) in overcoming a spurious correlation present in the source domain of the Waterbirds dataset.

Experiences of pain and pain management in advanced disease and serious illness for people from South Asian communities in Leeds and Bradford: a qualitative interview study

BackgroundPain is a significant problem for many people with advanced disease or a serious illness. Culture and ethnicity can affect the experience and management of pain. However, there is limited research in South Asian communities in the UK on their experiences of pain. The aim of this study is to explore the experiences and attitudes of patients and family carers from South Asian communities about pain and its management within advanced disease or serious illness.MethodsQualitative thematic analysis based on descriptive phenomenology (Sundler et al. 2019). Qualitative semi-structured interviews with patients or family carers from South Asian communities (N = 15). Interviews were recorded, transcribed and analysed using an inductive approach. Public and Patient Involvement representatives from British South Asian communities were consulted for guidance.ResultsThere were five key themes from the interviews: The importance of communication about pain with healthcare professionals; Concerns about taking pain medication; Personal resilience, privacy and self-management; Gender, culture and pain; Home pain management as struggle and frustration.ConclusionTo improve pain management for people from South Asian communities with advanced disease or a serious illness, there are a number of important issues for healthcare professionals from palliative and primary care services to address. These include: greater awareness around people’s fears and concerns about pain medication; their potential use of alternative pain management strategies; and cultural issues such as resilience, privacy, dignity and gender roles. Effective communication between doctors, patients and family members could be improved by using a ‘cultural humility’ model; providing clear and accessible pain medication information; understanding and taking account of people with both low, and medium levels, of English language proficiency; and improving patient trust. Additionally, improvements to out of hours services could improve pain management for all patients managing their pain at home.

Exploratory RCT of a group psychological intervention for postnatal depression in British mothers of South Asian origin – ROSHNI-D

BackgroundPostnatal depression (PND) is a global public health problem. There is a high prevalence of PND amongst ethnic minority women and major ethnic inequalities in mental health care in the U.K. Language and cultural barriers pose a significant challenge for access to timely treatment and interventions for British South Asian (BSA) women with PND. MethodsThe study, carried out in Manchester and Lancashire, England, was a two-arm single-blind exploratory randomised controlled trial. BSA women (N = 83) having a baby <12 months were randomised either to the group receiving the culturally adapted Positive Health Programme (PHP) (n = 42) or to the group receiving treatment as usual (TAU) (n = 41). Follow-up assessments were at 3 months (end of intervention) and 6 months after randomisation. ResultsUsing an intention to treat analysis, there was no significant difference between PHP intervention and TAU groups in depression measured using Hamilton Depression Rating Scale both at 3 and 6 months follow up. Using modified intention to treat analysis, women who attended four or more sessions showed significant reduction in depression in the PHP group compared to the TAU group and the greater number of sessions attended was associated with greater reductions in depression scores. LimitationsThe sample was relatively small and the study was conducted in one geographical area in Northwest England; hence, these results may not be generalizable to other regions and populations. ConclusionThe recruitment and trial retention figures highlighted the ability of the research team to engage with BSA women, having implications in planning services for this group.

Ethnicity, hypermobility syndrome and Ehlers-Danlos syndrome: A study based on hospital admissions

The purpose of the study was to identify any evidence of different patterns of disease for Ehlers Danlos Syndrome (EDS) and Hypermobility Syndrome (JHS) in the White British and South Asian communities in England. The numbers of hospital in-patients in ten NHS Trusts, between 2016 and 2020, in whom a diagnosis of EDS or JHS had been recorded were identified through Freedom of Information (FOI) requests. The condition was either the primary diagnosis or a secondary one, incidental to the reason for admission. The ten Trusts were selected because they served areas with a significant South Asian population and had been involved in previous studies of discrimination in the delivery of care. The study also assessed whether there was evidence of any of the Trusts underserving their South Asian community with lesser levels of recognition of EDS and JHS. Overall South Asian patients were almost four times more likely to have been diagnosed as having JHS. This proportion was statistically significant (z = -11.69, p &lt;0.00001). In Burton and Derby, Cambridge and Leicester the proportion of South Asian patients diagnosed as having EDS was significantly lower than in other Trusts (z = 9.4, p &lt;0.00001). This was also the case for JHS (z = 8.09, p &lt; 0.00001). This would indicate that in these three Trusts both conditions are underdiagnosed in the South Asian community. The significance of these findings is discussed.

The impact of race/ethnicity on the clinical outcomes of people with type 2 diabetes admitted to hospital with COVID-19: an observational multi-national analysis

Aims: To describe the relationship between race/ethnicity and adverse outcomes related to coronavirus disease 2019 (COVID-19) in adults with T2DM admitted to hospital in the UK, France and USA. Methods: Study data from the UK ABCD nationwide COVID- 19 audit, the French CORONADO nationwide initiative and the USA AMERICADO multi-centre study were analysed to assess the association between race/ethnicity and severe COVID-19. Severe COVID-19 was defined as death in hospital and/or admission to the intensive care unit (ICU). Logistic regression models were used to generate age-adjusted odds ratios. Results: Data from 3,471 patients in the ABCD audit, from 2,451 CORONADO patients and from 9,321 AMERICADO patients admitted with COVID-19 and T2DM were analysed. Race/ethnicity data were available for 3,410 (98%), 2,173 (89%) and 8,893 (95%) patients, respectively. In the UK ABCD audit cohort, Asian and Black race/ethnicity were associated with an increased risk of death/ICU admission compared to White when adjusted for age and sex (OR 2.14; 1.38-3.29 and OR 2.09; 1.17-3.74, respectively). When adjusted for additional confounders the association was stronger (Asian OR 2.88; 1.72-4.82 and Black OR 2.20; 1.12-4.30). In the CORONADO cohort Middle Eastern/North African race/ethnicity was protective against death/ICU admission (OR 0.57; 0.36-0.91). There was no association between ethnicity and death alone in the AMERICADO dataset. Conclusion: In those with T2DM admitted to hospital with COVID-19, a non-White race/ethnicity was associated with higher risk of death/ICU admission in the UK ABCD data but not in French CORONADO or USA AMERICADO datasets. Further research is required to improve our understanding of the observed discrepancies in outcomes.
