Background The prevalence of type 2 diabetes is increasing rapidly, particularly among younger adults. It is estimated that people with diabetes die, on average, six years earlier than people without diabetes. Our aim was to provide reliable estimates of the associations of age at diagnosis of diabetes with all-cause and cause-specific mortality an...

Background The SCORE2 risk model has been recommended for cardiovascular risk assessment in individuals aged over 40 years without diabetes in 4 defined risk regions of Europe. We aimed to validate a novel SCORE2-DM model in Type 2 diabetes with additional risk factors mainly based on UK datasets, using federated databases from the EUBIROD network....
Article
Background The 2021 ESC guideline on cardiovascular disease (CVD) prevention qualitatively categorizes moderate and severe chronic kidney disease (CKD) as high and very-high CVD risk status regardless of other factors like age and does not include estimated glomerular filtration rate (eGFR) and albuminuria in its algorithms, SCORE2 and SCORE2-OP, t...
Article
Background The life expectancy free of cardiovascular disease (CVD) in individuals without previous CVD can be estimated with the LIFEtime-perspective CardioVascular Disease (LIFE-CVD) model, as recommended by the 2021 ESC CVD prevention guidelines. Our aim was to systematically recalibrate the LIFE-CVD model to four European risk regions using con...

Leukocyte telomere length (LTL) is a proposed marker of biological age. Here we report the measurement and initial characterization of LTL in 474,074 participants in UK Biobank. We confirm that older age and male sex associate with shorter LTL, with women on average ~7 years younger in ‘biological age’ than men. Compared to white Europeans, LTL is...

Funding Acknowledgements Type of funding sources: None. Background Cardiovascular diseases (CVD) are the leading causes of death in China. Since population CVD incidence and risk factor levels vary considerably across regions in China, geo-specific investment in the prevention of CVD could be advantageous. Risk prediction models are an integral pa...
Article
Logistic regression is often used instead of Cox regression to analyse genome-wide association studies (GWAS) of single-nucleotide polymorphisms (SNPs) and disease outcomes with cohort and case-cohort designs, as it is less computationally expensive. Although Cox and logistic regression models have been compared previously in cohort studies, this w...

\textbf{Aims}$ Darapladib, a potent inhibitor of lipoprotein-associated phospholipase A$_{2}$ (Lp-PLA$_{2}$), has not reduced risk of cardiovascular disease outcomes in recent randomized trials. We aimed to test whether Lp-PLA$_{2}$ enzyme activity is causally relevant to coronary heart disease. $\textbf{Methods }$ In 72,657 patients with coronary...
Article
Many common variants have been associated with hematological traits, but identification of causal genes and pathways has proven challenging. We performed a genome-wide association analysis in the UK Biobank and INTERVAL studies, testing 29.5 million genetic variants for association with 36 red cell, white cell, and platelet properties in 173,480 Eu...

CONTEXT The value of assessing various emerging lipid-related markers for prediction of first cardiovascular events is debated. OBJECTIVE To determine whether adding information on apolipoprotein B and apolipoprotein A-I, lipoprotein(a), or lipoprotein-associated phospholipase A2 to total cholesterol and high-density lipoprotein cholesterol (HDL-...
Article
BACKGROUND: Persistent inflammation has been proposed to contribute to various stages in the pathogenesis of cardiovascular disease. Interleukin-6 receptor (IL6R) signalling propagates downstream inflammation cascades. To assess whether this pathway is causally relevant to coronary heart disease, we studied a functional genetic variant known to aff...

Uncertainties persist about the magnitude of associations of diabetes mellitus and fasting glucose concentration with risk of coronary heart disease and major stroke subtypes. We aimed to quantify these associations for a wide range of circumstances. We undertook a meta-analysis of individual records of diabetes, fasting blood glucose concentration...
Article
Whether triglyceride-mediated pathways are causally relevant to coronary heart disease is uncertain. We studied a genetic variant that regulates triglyceride concentration to help judge likelihood of causality. We assessed the -1131T>C (rs662799) promoter polymorphism of the apolipoprotein A5 (APOA5) gene in relation to triglyceride concentration,...
Article
We recruited a population-based sample of 58 males and 74 females aged 20-79 from a primary care medical practice to provide normative and descriptive data for high-resolution peripheral quantitative computed tomography (pQCT) parameters. Important effects of ageing and contrasts in the effects of sex on the micro-architecture and strength of upper...

One difficulty in performing meta-analyses of observational cohort studies is that the availability of confounders may vary between cohorts, so that some cohorts provide fully adjusted analyses while others only provide partially adjusted analyses. Commonly, analyses of the association between an exposure and disease either are restricted to cohort...
Conference Paper
While estimates of relative risks associated with fracture risk factors such as age and bone mineral density (BMD) may be of interest for etiologic and comparative purposes, public health questions such as who might benefit most from preventive interventions or BMD monitoring depend on estimates of absolute fracture risk. We estimated these absolut...

To quantify the rate of recurrence of acute anterior uveitis (AAU), and evaluate the influence of associated risk factors. We retrospectively reviewed the case notes of 185 patients with acute anterior uveitis, from their time of presentation to August 2001. The time to the first three recurrences of AAU from the onset of the disease was recorded,...
Article
While the determinants of BMD change have been studied in women, there have been few longitudinal studies in men. As part of the Network in Europe for Male Osteoporosis (NEMO) study, data were analysed from 1337 men and 1722 women aged 50-86y (mean=67 years) from 13 centres across Europe to assess determinants of BMD change and between-gender contr...
Article
Introduction: For a fixed weight, a wider bone of standardised length is stiffer. But moving the cortices away from the centre of mass risks creating structural (elastic) instability, and hip fractures have been postulated to occur as a consequence of buckling of the thinned supero-lateral femoral neck cortex during a fall. We hypothesised that st...

Osteoporosis is a serious complication of anorexia nervosa and in affected adolescents may result in a permanent deficit in bone mass. The pathophysiology of this bone disease has not been clearly defined. In this prospective study of 26 young women with anorexia nervosa aged 13-20 years (mean 16.5) we have measured changes in bone mineral density,...
Article
Population studies suggest that rib fractures are associated with a reduction in bone mass. While much is known about the predictive risk of hip, spine and distal forearm fracture on the risk of future fracture, little is known about the impact of rib fracture. The aim of this study was to determine whether a recalled history of rib fracture was as...

Plasma fibrinogen levels may be associated with the risk of coronary heart disease (CHD) and stroke. To assess the relationships of fibrinogen levels with risk of major vascular and with risk of nonvascular outcomes based on individual participant data. Relevant studies were identified by computer-assisted searches, hand searches of reference lists...
Article
We have previously shown that center- and sex-specific fall rates explained one-third of between-center variation in upper limb fractures across Europe. In this current analysis, our aim was to determine how much of the between-center variation in fractures could be attributed to repeated falling, bone mineral density (BMD), and other risk factors...
Article
In vivo bone densitometry is affected by measurement inaccuracies arising from the assumptions made about soft tissue and marrow composition. This study tested the hypothesis that section modulus (SM, a measure of bending resistance) when measured ex vivo, would discriminate cases of hip fracture from controls better than areal bone mineral density...
Article
We hypothesized that measures of physical activity would have a closer relationship with section modulus (SM), an indicator of bending resistance, than with bone mineral density (BMD) because physical activity might expand the bony envelope, which tends to reduce BMD for a constant bone mineral content. Four hundred twenty-three men and 436 women (...
Article
We measured the impact of diet, anthropometry, physical activity and lifestyle variables on rates of hip bone mineral density (BMD) loss in 470 white men and 474 white women aged 67-79 years at recruitment dwelling in the community. The subjects were recruited from a prospective population-based diet and cancer study (EPIC-Norfolk) in Eastern Engla...

For example, innovative digital health interventions can be an effective strategy to reduce cardiovascular risk, 22 clonal hematopoiesis of indeterminate potential links to an increased risk of CVD due to the role of inflammasomes, 23 polygenic risk scores-triaged coronary artery calcium score for subclinical coronary artery disease. 24 In fact, moderate and severe chronic kidney disease measures may improve CVD risk prediction, 25 and CVD events (such as AF, HF, and stroke) strongly and independently associate with future risk of kidney failure with replacement therapy. 26 As a potential means for CVD risk stratification, artificial intelligence-based ocular image analysis 27 contributes to the identification and prediction of CVD risks and events. ...
... The original data of our study was from public datasets. Summarized GWAS data for TL (ieu-b-4879) 23 , hypertension (ukb-b-12493), and BMI (ukb-b-2303) were downloaded via the MRC-IEU OpenGWAS database (https:// gwas. mrcieu. ...
... age as time in addition to event status). In contrast, logistic regression showed greater statistical power in the case-cohort setting (14), but it also tended to produce inflated effect estimates, especially for genetic variants with a more pronounced impact on the disease. In the case-cohort design, a random sub-cohort is drawn from the initial cohort, which includes cases at the same event occurrence prevalence, and all other cases outside the subsample (15). ...
... [51][52][53] Previous research across European, South Asian, and East Asian populations has identified five functional variants including four loss of function variants resulting in up to 64% lower levels of Lp-PLA 2 activity. 54 In addition, past studies have not excluded participants who are consuming medications known to lower Lp-PLA 2 levels such as statins, ezetimibe, fibrates, PCSK9 inhibitors, hormone replacement therapy, niacin or orlistat, [55][56][57][58] or dietary supplements such as fish oils and omega-3 fatty acids. 59,60 To date, no study has examined the relationship between these two novel markers and traditional risk factors in a western population where strict exclusion criteria were applied. ...
... This SNP, located in the 3' untranslated region of the serine/ threonine-protein kinase gene TAOK2, has a CADD score of 18.16, suggesting deleteriousness, and a RegulomeDB score of 1f (eQTL + transcription factor binding/DNase peak), suggesting that this SNP is likely to affect transcription factor binding and linked to expression of a gene target. Furthermore, rs9924686 is an eQTL for several genes, including genes associated with metabolic and immunological traits [56,57] (YPEL3 and INO80E in adipose tissue and several brain tissues) and alcohol intake [57,58] (PPP4C and MVP in cultured cell fibroblasts). ...
... A total of 35,144 patients with AAA and 2,572,386 controls were investigated independently in 16 studies [20,[23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. Many studies had overlapping cohorts by using the same datasets to conduct analyses on their respective causal risk factors, with the most common overlaps occurring with the UK biobank (9 studies) [23,27-2 9,31,34,36-38] and the Utrecht Netherlands dataset (4 studies) [20,25,32,33]. ...

... Lipoprotein- associated phospholipase A 2 (Lp-PLA 2 ) is an enzyme produced by inflammatory cells which is believed to contribute to atherogenesis in humans [2]. Numerous epidemiologic studies suggest that high levels of circulating Lp-PLA 2 are associated with cardiovascular events and stroke [3][4][5]. In the Rotterdam case-cohort study, high Lp-PLA 2 activity was also independently associated with the risk of developing dementia (HR = 1.56 for highest quartile relative to lowest; 95% CI 1.03-2.37); ...
... In addition, a group of diseases named cardiometabolic disease (CMD), including stroke, T2DM, and heart disease, has received increasing attention in this aging society, as it is positively related to a short life expectancy. 38 The coexistence of two or more CMDs would be considered cardiometabolic multimorbidity, which is associated with a higher mortality rate and other adverse health incidents. 39 S 2 I 2 N 0-3 score predicts short-and long-term mortality and morbidity in HFrEF It is interesting to find that the S 2 I 2 N 0-3 score contains three factors (stroke history, insulin for DM, and NT-proBNP level), which could correspond to the three diseases of CMD, and therefore, the positive relationships between the S 2 I 2 N 0-3 score and mortality and morbidity are reasonable and may be partially explained by the CMDs. ...
