Impact of Indoxyl Sulfate on Coronary Plaques in Patients on Hemodialysis.

This study aimed to interpret the association between serum IS levels and coronary plaque burden (CPB) or CAC.A total of 30 consecutive patients on hemodialysis, who underwent 320-row coronary multidetector computed tomography (MDCT) angiography for suspected coronary artery disease, were enrolled in this prospective study. Coronary artery percent atheroma volume (a CPB marker) and percent calcium volume (a CAC marker) assessed using MDCT were evaluated. Furthermore, various oxidative and inflammatory markers typified by serum IS levels at a dialysis-free day were measured. Using these data, we investigated correlation between the inflammatory marker IS and CPB or CAC.Multivariable analysis indicated that serum IS levels were positively correlated with CAC [partial regression coefficient, 2.89; 95% confidence interval (CI), 0.35-5.43; P = 0.03] but not with CPB, even after adjustment for cofounders. Composite cardiovascular events, namely, as all-cause death, non-fatal myocardial infarction, disabling stroke, and hospital admission for other cardiovascular events, were reported to be 50% in all patients (95% CI, 32.1-67.9).In patients undergoing hemodialysis, serum IS levels were significantly associated with CAC but not with CPB.

Background: It is not established to what extent self-monitoring of home BP be lowered in patients with type 2 diabetes. We tested the hypothesis that the appropriate home morning SBP cutoff value is 125 mmHg in our stratification of cardiovascular risk in type 2 diabetes. Method: Clinic and home BP monitoring were performed in 4308 individuals (1057 people with diabetes and 3251, nondiabetes), and we tested two cutoff values of home morning SBP (MSBP): 135 and 125 mmHg. Multivariable Cox regression analyses adjusting for age, sex, body mass index, history of cardiovascular events, presence of chronic kidney disea...

In conclusion, in the Framingham Heart Study population, in the last 30 years, disease duration in persons with dementia has decreased. However, age-adjusted mortality risk has slightly decreased after 1977-1983. Consequences of such trends on dementia prevalence should be investigated. Recent Research on the Benefits of Exercise in Later Life https://www.fightaging.org/archives/2018/04/recent-research-on-the-benefits-of-exercise-in-later-life/ A sizable body of work points to the ability of older individuals to continue to obtain benefits through regular physical activity, and particularly in the case ...

In this study, we assessed if activation of the demethylase affects arterial stiffening and hypertension in aged mice. The Klotho gene was originally identified as a putative aging-suppressor gene in mice that extended lifespan when overexpressed and caused multiple premature aging phenotypes when disrupted. The Klotho level decreases with age, while the prevalence of arterial stiffness and hypertension increases with age. At age 70 years, the serum level of Klotho is only about one half of what it was at age 40 years. Moreover, the serum Klotho level is significantly decreased in patients with arterial stiffness in...

Authors: Ha KH, Kim B, Shin HS, Lee J, Choi H, Kim HC, Kim DJ Abstract BACKGROUND AND OBJECTIVES: To compare cardiovascular disease (CVD) risk associated with 5 different dipeptidyl peptidase-4 inhibitors (DPP-4is) in people with type 2 diabetes. METHODS: We identified 534,327 people who were newly prescribed sitagliptin (n=167,157), vildagliptin (n=67,412), saxagliptin (n=29,479), linagliptin (n=220,672), or gemigliptin (n=49,607) between January 2013 and June 2015 using the claims database of the Korean National Health Insurance System. A Cox proportional hazards model was used to estimate hazard ratios (HRs)...

ConclusionCKD of any stage was associated with an increased risk of postoperative major complication, and severe CKD was associated with increased mortality among patients undergoing pancreatectomy for malignancy. These associations were not diminished in elderly patients. Our findings could inform preoperative counseling and decision-making.

Authors: Lin TC, Lu TM, Huang FC, Hsu PF, Shih CC, Lin SJ, Hsu CP Abstract Percutaneous coronary intervention (PCI) has emerged as an alternative treatment to coronary artery bypass grafting (CABG) in patients with unprotected left main coronary artery disease (ULMCAD). However, the optimal treatment for ULMCAD concomitant with chronic kidney disease (CKD) was rarely addressed. Herein, we compare the long-term outcomes of these patients treated with CABG or PCI.From January 2004 to December 2010, 185 patients with ULMCAD and CKD undergoing PCI (n = 84) or CABG (n = 101) were matched for the selection criteria. The ...

In conclusion, senescence of vascular cells promotes the development of age-related disorders, including heart failure, diabetes, and atherosclerotic diseases, while suppression of vascular cell senescence ameliorates phenotypic features of aging in various models. Recent findings have indicated that specific depletion of senescent cells reverses age-related changes. Although the biological networks contributing to maintenance of homeostasis are extremely complex, it seems reasonable to explore senolytic agents that can act on specific cellular components or tissues. Several clinical trials of senolytic agents are currentl...

Conclusions Patients without diagnosed AF but with certain risk factors were at a particularly high cardiovascular risk and may require new prevention approaches. In addition to the ongoing trials, future trials in other high-risk populations, e.g., diabetes and chronic kidney disease may be warranted.

Abstract Although guidelines recommend strict blood pressure (BP) control in patients with type 2 diabetes mellitus (T2DM) and elevated cardiovascular risk, the long‐term effects of this approach are unknown. We investigated the effect of intensive BP control on clinical outcomes in patients with T2DM over 9 years of follow‐up. We included ACCORD BP participants in the standard glucose control arm who had established cardiovascular disease, chronic kidney disease, age ≥75 years or 10‐year coronary heart risk ≥15%. Participants were randomized to either intensive (systolic BP
