The ESR1 (6q25) locus is associated with calcaneal ultrasound parameters and radial volumetric bone mineral density in European men

<p><b>Purpose:</b> Genome-wide association studies (GWAS) have identified 6q25, which incorporates the oestrogen receptor alpha gene (ESR1), as a quantitative trait locus for areal bone mineral density (BMD(a)) of the hip and lumbar spine. The aim of this study was to determine the influence of this locus on other bone health outcomes; calcaneal ultrasound (QUS) parameters, radial peripheral quantitative computed tomography (pQCT) parameters and markers of bone turnover in a population sample of European men.</p> <p><b>Methods:</b> Eight single nucleotide polymorphisms (SNP) in the 6q25 locus were genotyped in men aged 40-79 years from 7 European countries, participating in the European Male Ageing Study (EMAS). The associations between SNPs and measured bone parameters were tested under an additive genetic model adjusting for centre using linear regression.</p> <p><b>Results:</b> 2468 men, mean (SD) aged 59.9 (11.1) years had QUS measurements performed and bone turnover marker levels measured. A subset of 628 men had DXA and pQCT measurements. Multiple independent SNPs showed significant associations with BMD using all three measurement techniques. Most notably, rs1999805 was associated with a 0.10 SD (95%CI 0.05, 0.16; p = 0.0001) lower estimated BMD at the calcaneus, a 0.14 SD (95%CI 0.05, 0.24; p = 0.004) lower total hip BMD(a), a 0.12 SD (95%CI 0.02, 0.23; p = 0.026) lower lumbar spine BMD(a) and a 0.18 SD (95%CI 0.06, 0.29; p = 0.003) lower trabecular BMD at the distal radius for each copy of the minor allele. There was no association with serum levels of bone turnover markers and a single SNP which was associated with cortical density was also associated with cortical BMC and thickness.</p> <p><b>Conclusions:</b> Our data replicate previous associations found between SNPs in the 6q25 locus and BMD(a) at the hip and extend these data to include associations with calcaneal ultrasound parameters and radial volumetric BMD.</p&gt

The BELFRAIL (BFC80+) study: a population-based prospective cohort study of the very elderly in Belgium

In coming decades the proportion of very elderly people living in the Western world will dramatically increase. This forthcoming "grey epidemic" will lead to an explosion of chronic diseases. In order to anticipate booming health care expenditures and to assure that social security is funded in the future, research focusing on the relationship between chronic diseases, frailty and disability is needed. The general aim of the BELFRAIL cohort study (BFC80+) is to study the dynamic interaction between health, frailty and disability in a multi-system approach focusing on cardiac dysfunction and chronic heart failure, lung function, sarcopenia, renal insufficiency and immunosenescence

Drug prescriptions unadapted to the renal function in patients aged 80 years and older (a.)

Background: Drug-related problems are common in older people. Often they are related to low estimated glomerular filtration rate (eGFR), which has a high prevalence among older adults. The aim of this study was to investigate inappropriate drug prescriptions and dose adaptations in a very old population and their relationship with the eGFR. Method: Design: A cross-sectional study within a Belgian prospective population-based cohort study (the BELFRAIL study) of 539 participants aged 80 years and older (mean age 85 years). Drug prescriptions at inclusion were reported by the participant's responsible general practitioner. The eGFR was estimated using the MDRD equation. Based on their eGFR, the participants were divided in three groups: > 50, 30-50 and < 30 ml/min/1.73 m², respectively. Drug prescriptions were analysed in different eGFR groups. The prevalence and odds ratios of inappropriate drugs and the unadjusted defined daily doses (DDD) of the participant eGFRs were calculated. Results: Thirty-six (of 111) and eight (of 31) of the participants with an eGFR between 30-50 and < 30 ml/min/1.73 m², respectively, had at least one inappropriate drug prescribed. No decrease in mean DDD, was observed in any prescribed drug in both lower eGFR groups. Participants with a lower eGFR were at higher risk of receiving gliclazide (OR: 4.51; 95% CI: 1.45-14.02) or unadjusted doses of allopurinol (OR: 3.48; 95% CI: 1.26-9.61). Conclusion: Drug prescriptions inappropriate for patient eGFR are common in subjects aged 80 years and older, despite automatic eGFR reporting

The correlation between blood pressure and kidney function decline in older people: a registry-based cohort study.

Objectives To examine the relation between static and dynamic blood pressure (BP) measurements and the evolution of kidney function in older people, adjusted for the presence of multimorbidity. Design Retrospective cohort study during a 10-year time interval (2002–2012) in three age strata of patients aged 60 and older. Setting Primary care registration network with 97 general practitioners working in 55 practices regularly submitting collected patient data. Participants All patients with at least one BP measurement in 2002 and at least four serum creatine measurements after 2002 (n=8636). A modified Charlson Comorbidity Index (mCCI) at baseline was registered. Change in systolic and diastolic BP (DBP) and pulse pressure (PP) from 2002 onwards was calculated. The relation between kidney function evolution and baseline BP and change in BP was examined using linear and logistic regression analysis. Main outcome measures The slope of the estimated glomerular filtration rate (eGFR, MDRD, Modification of Diet in Renal Disease equation) was calculated by the ordinal least square method. A rapid annual decline of kidney function was defined as ≥3 mL/min/1.73 m2/year. Results Rapid annual decline of kidney function occurred in 1130 patients (13.1%). High baseline systolic BP (SBP) and PP predicted kidney function decline in participants aged 60–79 years. No correlation between baseline BP and kidney function decline was found in participants aged 80 years and older. An annual decline of ≥1 mm Hg in SBP and PP was a strong risk factor for a rapid annual kidney function decline in all age strata, independent of baseline BP and mCCI. A decline in DBP as also a strong independent predictor in participants aged 60–79 years. Conclusions The present study identified a decline in BP over time as a strong risk factor for kidney function decline in all age strata, adjusted for mCCI and baseline kidney function and BP.</p
