Association of change in cardiovascular risk factors with incident cardiovascular events

Importance: There is consistent evidence of the association between ideal cardiovascular health and lower incident cardiovascular disease (CVD); however, most studies used a single measure of cardiovascular health.Objective: To examine how cardiovascular health changes over time and whether these changes are associated with incident CVD.Design, Setting, and Participants: Prospective cohort study in a UK general community (Whitehall II), with examinations of cardiovascular health from 1985/1988 (baseline) and every 5 years thereafter until 2015/2016 and follow-up for incident CVD until March 2017.Exposures: Using the 7 metrics of the American Heart Association (nonsmoking; and ideal levels of body mass index, physical activity, diet, blood pressure, fasting blood glucose, and total cholesterol), participants with 0 to 2, 3 to 4, and 5 to 7 ideal metrics were categorized as having low, moderate, and high cardiovascular health. Change in cardiovascular health over 10 years between 1985/1988 and 1997/1999 was considered.Main Outcome and Measure: Incident CVD (coronary heart disease and stroke).Results: The study population included 9256 participants without prior CVD (mean [SD] age at baseline, 44.8 [6.0] years; 2941 [32%] women), of whom 6326 had data about cardiovascular health change. Over a median follow-up of 18.9 years after 1997/1999, 1114 incident CVD events occurred. In multivariable analysis and compared with individuals with persistently low cardiovascular health (consistently low group, 13.5% of participants; CVD incident rate per 1000 person-years, 9.6 [95% CI, 8.4-10.9]), there was no significant association with CVD risk in the low to moderate group (6.8% of participants; absolute rate difference per 1000 person-years, -1.9 [95% CI, -3.9 to 0.1]; HR, 0.84 [95% CI, 0.66-1.08]), the low to high group, (0.3% of participants; absolute rate difference per 1000 person-years, -7.7 [95% CI, -11.5 to -3.9]; HR, 0.19 [95% CI, 0.03-1.35]), and the moderate to low group (18.0% of participants; absolute rate difference per 1000 person-years, -1.3 [95% CI, -3.0 to 0.3]; HR, 0.96 [95% CI, 0.80-1.15]). A lower CVD risk was observed in the consistently moderate group (38.9% of participants; absolute rate difference per 1000 person-years, -4.2 [95% CI, -5.5 to -2.8]; HR, 0.62 [95% CI, 0.53-0.74]), the moderate to high group (5.8% of participants; absolute rate difference per 1000 person-years, -6.4 [95% CI, -8.0 to -4.7]; HR, 0.39 [95% CI, 0.27-0.56]), the high to low group (1.9% of participants; absolute rate difference per 1000 person-years, -5.3 [95% CI, -7.8 to -2.8]; HR, 0.49 [95% CI, 0.29-0.83]), the high to moderate group (9.3% of participants; absolute rate difference per 1000 person-years, -4.5 [95% CI, -6.2 to -2.9]; HR, 0.66 [95% CI, 0.51-0.85]), and the consistently high group (5.5% of participants; absolute rate difference per 1000 person-years, -5.6 [95% CI, -7.4 to -3.9]; HR, 0.57 [95% CI, 0.40-0.80]).Conclusions and Relevance: Among a group of participants without CVD who received follow-up over a median 18.9 years, there was no consistent relationship between direction of change in category of a composite metric of cardiovascular health and risk of CVD

Association of hearing impairment with incident depressive symptoms: a community-based prospective study

Objective: The aim was to investigate the potential association between hearing impairment and incident depressive symptoms.Methods: Using a prospective community-based cohort study in France (the Paris Prospective Study III), participants aged 50-75 years were recruited between 2008 and 2012 and thereafter followed up every 2 years up to 2018. Hearing impairment, measured at study recruitment by audiometry testing, was defined as a pure tone average >25 decibels in the better ear. Incident depressive symptoms, measured using the validated 13-item Questionnaire of Depression 2nd version, was assessed during follow-up. Multivariate generalized estimating equations were used to compute odds ratio (OR) and 95% confidence intervals (CI).Results: Among 7591 participants free of depressive symptoms at baseline (mean age 59.8 years, 63% of men), 14.3% had hearing impairment. Over 6 years of follow-up, 479 subjects (6.3%) had incident depressive symptoms. The OR for incident depressive symptoms was 1.36 for subjects with baseline hearing impairment (95% CI, 1.06-1.73). A pooled analysis of 4 published prospective studies yielded a multivariable relative risk of baseline hearing impairment for incident depressive symptoms of 1.29 (95% CI, 1.09-1.53).Conclusions: In this community-based prospective cohort study of participants aged 50 to 75 years, baseline hearing impairment was associated with a 36% increased odds of incident depressive symptoms

Is the number of ideal cardiovascular health metrics in midlife associated with lower risk of cancer? Evidence from 3 European prospective cohorts

BACKGROUND: Primordial prevention may be a relevant strategy for the prevention of cancer. Given the commonality of risk factors and mechanisms between cancer and cardiovascular disease, we examined the associations between the number of ideal cardiovascular health metrics in midlife and incident cancer. METHODS: In 3 European cohorts (NutriNet-Santé and GAZEL, France; Whitehall II, United Kingdom), the number of ideal cardiovascular health metrics was determined at baseline (range 0-7). Follow-up for cancer events was until October 2020 (NutriNet-Santé), March 2017 (Whitehall II) and December 2015 (GAZEL). Cox regression was conducted in each cohort, and results were thereafter pooled using a random-effects model. RESULTS: Data were available on 39 718 participants. A total of 16 237 were from NutriNet-Santé (mean age 51.3 yr; 28% men), 9418 were from Whitehall II (mean age 44.8 yr; 68% men) and 14 063 were from GAZEL (mean age 45.2 yr; 75% men). The median follow-up was 8.1 years in NutriNet-Santé, 29.6 years in Whitehall II and 24.8 years in GAZEL, and yielded a total of 4889 cancer events. A greater number of ideal cardiovascular health metrics was associated with a lower overall cancer risk in each cohort, with an aggregate hazard ratio (HR) per 1 increment in number of ideal metrics of 0.91 (95% confidence interval [CI] 0.88-0.93). This association remained after removal of the smoking metric (aggregate HR per unit increment in number of ideal metrics: 0.94, 95% CI 0.90-0.97), and site-specific analysis demonstrated a significant association with lung cancer. INTERPRETATION: A greater number of ideal cardiovascular health metrics in midlife was associated with lower cancer risk, notably lung cancer. Primordial prevention of cardiovascular risk factors in midlife may be a complementary strategy to prevent the onset of cancer

Body silhouette trajectories across the lifespan and vascular aging: The Paris Prospective Study 3

Vascular aging is a major contributor to cardiovascular disease and can be quantified by higher carotid stiffness, intima-media thickness and diameter, and hypertension. Weight gain across the lifetime may be an important, modifiable determinant of vascular aging. We therefore aimed to assess lifetime body silhouette trajectories (a marker of weight change across the lifespan) in relation to vascular aging in late adulthood. We used cross-sectional data from a community-based cohort study (n=8243; age, 59.4; 38.7% women). A linear mixed model was used to assess trajectories of recalled body silhouettes from age 8 to 45 years. We assessed carotid artery properties (ultrasonography), resting hypertension (blood pressure ≥140/90 mm Hg or use of antihypertensives), and exaggerated exercise blood pressure, a marker of masked hypertension (systolic blood pressure ≥150 mm Hg during submaximal exercise) at study recruitment when the participants were 50 to 75 years of age. We identified 5 distinct body silhouette trajectories: lean stable (32.0%), lean increase (11.1%), moderate stable (32.5%), lean-marked increase (16.3%), and heavy stable (8.1%). Compared with individuals in the lean-stable trajectory, those in the moderate-stable, lean-marked increase, and heavy-stable trajectories had higher carotid stiffness, intima-media thickness and diameter (odds ratios between 1.23 and 2.10 for highest quartile versus lowest quartile of manifestations of vascular aging; PP<0.05). Vascular aging was most prominent among individuals who were lean in early life but markedly gained weight during young adulthood and among those who were heavy in early life and maintained weight

Carotid artery stiffness and incident depressive symptoms: The Paris Prospective Study III

Background: Arterial stiffness may contribute to late-life depression via cerebral microvascular damage, but evidence is scarce. No longitudinal study has evaluated the association between arterial stiffness and risk of depressive symptoms. Therefore, we investigated the association between carotid artery stiffness and incident depressive symptoms in a large community-based cohort study.Methods: This longitudinal study included 7013 participants (mean age 59.7 ± 6.3 years; 35.8% women) free of depressive symptoms at baseline. Carotid artery stiffness (high-resolution echo tracking) was determined at baseline. Presence of depressive symptoms was determined at baseline and at 4 and 6 years of follow-up, and was defined as a score ≥7 on the validated Questionnaire of Depression, Second Version, Abridged and/or new use of antidepressant medication. Logistic regression and generalized estimating equations were used.Results: In total, 6.9% (n = 484) of the participants had incident depressive symptoms. Individuals in the lowest tertile of carotid distensibility coefficient (indicating greater carotid artery stiffness) compared with those in the highest tertile had a higher risk of incident depressive symptoms (odds ratio: 1.43; 95% confidence interval: 1.10-1.87), after adjustment for age, sex, living alone, education, lifestyle, cardiovascular risk factors, and baseline Questionnaire of Depression, Second Version, Abridged scores. Results were qualitatively similar when we used carotid Young's elastic modulus as a measure of carotid stiffness instead of carotid distensibility coefficient, and when we used generalized estimating equations instead of logistic regression.Conclusions: Greater carotid stiffness is associated with a higher incidence of depressive symptoms. This supports the hypothesis that carotid stiffness may contribute to the development of late-life depression

Circulating N-Acetylaspartate does not track brain NAA concentrations, cognitive function or features of small vessel disease in humans

N-acetylaspartate (NAA) is the second most abundant metabolite in the human brain; although it is assumed to be a proxy for a neuronal marker, its function is not fully elucidated. NAA is also detectable in plasma, but its relation to cerebral NAA levels, cognitive performance, or features of cerebral disease has not been investigated. To study whether circulating NAA tracks cerebral NAA levels, and whether circulating NAA correlates with cognitive function and features of cerebral small vessel disease (SVD). Two datasets were analyzed. In dataset 1, structural MRI was acquired in 533 subjects to assess four features of cerebral SVD. Cognitive function was evaluated with standardized test scores (N = 824). In dataset 2, brain H-1-MRS from the occipital region was acquired (N = 49). In all subjects, fasting circulating NAA was measured with mass spectrometry. Dataset 1: in univariate and adjusted for confounders models, we found no correlation between circulating NAA and the examined features of cerebral SVD. In univariate analysis, circulating NAA levels were associated inversely with the speed in information processing and the executive function score, however these associations were lost after accounting for confounders. In line with the negative findings of dataset 1, in dataset 2 there was no correlation between circulating and central NAA or total NAA levels. This study indicates that circulating NAA levels do not reflect central (occipital) NAA levels, cognitive function, or cerebral small vessel disease in man

Effects of inaccuracies in arterial path length measurement on differences in MRI and tonometry measured pulse wave velocity

Abstract Background Carotid-femoral pulse wave velocity (cf-PWV) and aortic PWV measured using MRI (MRI-PWV) show good correlation, but with a significant and consistent bias across studies. The aim of the current study was to evaluate whether the differences between cf.-PWV and MRI-PWV can be accounted for by inaccuracies of currently used distance measurements. Methods One hundred fourteen study participants were recruited into one of 4 groups: Type 2 diabetes melltus (T2DM) with cardiovascular disease (CVD) (n = 23), T2DM without CVD (n = 41), CVD without T2DM (n = 25) and a control group (n = 25). All participants underwent cf.-PWV, cardiac MRI and whole body MR angiography(WB-MRA). 90 study participants also underwent aortic PWV using MRI. cf.-PWVEXT was performed using a SphygmoCor device (Atcor Medical, West Ryde, Australia). The true intra-arterial pathlength was measured using the WB-MRA and then used to recalculate the cf.-PWVEXT to give a cf.-PWVMRA. Results Distance measurements were significantly lower on WB-MRA than on external tape measure (mean diff = −85.4 ± 54.0 mm,p < 0.001). MRI-PWV was significantly lower than cf.-PWVEXT (MRI-PWV = 8.1 ± 2.9 vs. cf.-PWVEXT = 10.9 ± 2.7 ms−1,p < 0.001). When cf.-PWV was recalculated using the inter-arterial distance from WB-MRA, this difference was significantly reduced but not lost (MRI-PWV = 8.1 ± 2.9 ms−1 vs. cf.-PWVMRA 9.1 ± 2.1 ms−1, mean diff = −0.96 ± 2.52 ms−1,p = 0.001). Recalculation of the PWV increased correlation with age and pulse pressure. Conclusion Differences in cf.-PWV and MRI PWV can be predominantly but not entirely explained by inaccuracies introduced by the use of simple surface measurements to represent the convoluted arterial path between the carotid and femoral arteries

Effectiveness and cost-effectiveness of 'BeweegKuur', a combined lifestyle intervention in the Netherlands: Rationale, design and methods of a randomized controlled trial

<p>Abstract</p> <p>Background</p> <p>Improving the lifestyle of overweight and obese adults is of increasing interest in view of its role in several chronic diseases. Interventions aiming at overweight or weight-related chronic diseases suffer from high drop-out rates. It has been suggested that Motivational Interviewing and more frequent and more patient-specific coaching could decrease the drop-out rate. 'BeweegKuur' is a multidisciplinary lifestyle intervention which offers three programmes for overweight persons. The effectiveness and the cost-effectiveness of intensively guided programmes, such as the 'supervised exercise programme' of 'BeweegKuur', for patients with high weight-related health risk, remain to be assessed. Our randomized controlled trial compares the expenses and effects of the 'supervised exercise programme' with those of the less intensively supervised 'start-up exercise programme'.</p> <p>Methods/Design</p> <p>The one-year intervention period involves coaching by a lifestyle advisor, a physiotherapist and a dietician, coordinated by general practitioners (GPs). The participating GP practices have been allocated to the interventions, which differ only in terms of the amount of coaching offered by the physiotherapist. Whereas the 'start-up exercise programme' includes several consultations with physiotherapists to identify barriers hampering independent exercising, the 'supervised exercise programme' includes more sessions with a physiotherapist, involving exercise under supervision. The main goal is transfer to local exercise facilities. The main outcome of the study will be the participants' physical activity at the end of the one-year intervention period and after one year of follow-up. Secondary outcomes are dietary habits, health risk, physical fitness and functional capacity. The economic evaluation will consist of a cost-effectiveness analysis and a cost-utility analysis. The primary outcome measures for the economic evaluation will be the physical activity and the number of quality-adjusted life years. Costs will be assessed from a societal perspective with a time horizon of two years. Additionally, a process evaluation will be used to evaluate the performance of the intervention and the participants' evaluation of the intervention.</p> <p>Discussion</p> <p>This study is expected to provide information regarding the additional costs and effects of the 'supervised exercise programme' in adults with very high weight-related health risk.</p> <p>Trial registration number</p> <p>ISRCTN: <a href="http://www.controlled-trials.com/ISRCTN46574304">ISRCTN46574304</a></p

Benefits of flu vaccination for persons with diabetes mellitus: A review

Diabetes mellitus imposes a significant and increasing burden on society, with major consequences for human health, welfare and the economy worldwide. Persons with diabetes mellitus are at increased risk of developing severe complications after influenza virus infection and guidelines advise vaccination. The present evidence for influenza vaccine effectiveness in persons with diabetes mellitus is mainly based on observational studies with clinical endpoints like hospitalization and death, indicating a beneficial reduction of morbidity and mortality. Further supportive evidence comes from serological studies, in which persons with diabetes mellitus usually develop similar antibody levels after vaccination as healthy people. Observational studies may be prone to selection bias, and serological studies may not completely mirror vaccine effectiveness in the field. Although more controlled trials in persons with diabetes mellitus with laboratory-confirmed, influenza-specific outcomes would be desirable to better estimate the effect of vaccination, the currently available data justify routine influenza vaccination in persons with diabetes mellitus. As in this risk group, the use of influenza vaccine is far below target worldwide, efforts should be made to increase vaccination coverage.status: publishe
