Background -Atherosclerotic peripheral artery disease (PAD) affects 8-12% of Americans over 65 and is associated with a major decline in functional status, increased myocardial infarction and stroke rates, and increased risk of ischemic amputation. Current treatment strategies for claudication have limitations. PACE is an NHLBI-sponsored, randomized, double-blind, placebo-controlled phase 2, exploratory clinical trial designed to assess safety and efficacy of autologous bone marrow-derived aldehyde dehydrogenase bright (ALDHbr) cells in PAD patients and to explore associated claudication physiologic mechanisms...

A 63-year-old male was diagnosed as having chronic phase CML in 2001. He obtained a major molecular response with imatinib (IM). In 2012, amulodipin was started for hypertension. In January 2013, IM was switched to nilotinib (NIL) in a clinical trial, and in February 2015, NIL was discontinued because MR(4.5) had been maintained for two years. One month later, he was admitted to our hospital because of headache and high blood pressure (194/108 mmHg). His urine test showed protein 3+ and occult blood 2+. His eGFR rapidly deteriorated from 45...

Although recent studies show that age-related hearing impairment is associated with cerebral changes, data from a population perspective are still lacking. Therefore, we studied the relation between hearing impairment and brain volume in a large elderly cohort. From the population-based Rotterdam Study, 2,908 participants (mean age 65 years, 56% female) underwent a pure-tone audiogram to quantify hearing impairment. By performing MR imaging of the brain we quantified global and regional brain tissue volumes (total brain volume, gray matter volume, white matter (WM) volume, and lobe-specific volumes)...

During the past decade, combined PET/MRI has been translated from a basic technical concept to a clinical research tool and a clinically applied hybrid imaging modality. Numerous clinical and scientific applications have been proposed for this novel hybrid modality including oncologic, neurologic and cardiovascular imaging. Among these, PET/MRI in children has emerged as a key application, not only due to possible diagnostic advantages but also because of reduced radiation exposure compared to alternative techniques...

Steroid hormones like aldosterone have been conclusively shown to elicit both late genomic and rapid, nongenomically initiated responses. Aldosterone was among the first for which rapid, clinically relevant effects were even shown in humans. Yet, after over 30 years of research, the nature of receptors involved in rapid actions of aldosterone is still unclear. Such effects may be assigned to the classical, intracellular steroid receptors, in this case mineralocorticoid receptors (MR, class IIa action Mannheim classification)...

BACKGROUND: Patients undergoing vascular surgery are prone to perioperative organ injury because of both higher prevalence of cardiovascular risk factors and the extent of surgery. Early detection of organ failure is essential to facilitate appropriate medical care. Midregional pro-adrenomedullin (MR-proADM) has been investigated in acute medical care settings to guide clinical decision-making regarding patient pathways and to identify patients prone to imminent cardiovascular or inflammatory complications...

Methionine restriction (MR) extends lifespan across different species. The main responses of rodent models to MR are well-documented in adipose tissue (AT) and liver, which have reduced mass and improved insulin sensitivity, respectively. Recently, molecular mechanisms that improve healthspan have been identified in both organs during MR. In fat, MR induced a futile lipid cycle concomitant with beige AT accumulation, producing elevated energy expenditure. In liver, MR upregulated fibroblast growth factor 21 and improved glucose metabolism in aged mice and in response to a high-fat diet...

: We assessed the effects of liraglutide treatment on five cardiovascular risk biomarkers, reflecting different pathophysiology: 1) Tumour necrosis factor-alpha (TNF-alpha); 2) Soluble urokinase plasminogen activator receptor (suPAR); 3) Mid-regional pro-adrenomedullin (MR-proADM); 4) Mid-regional pro-atrial natriuretic peptide (MR-proANP); and 5) Copeptin, in type 2 diabetes patients with albuminuria. In a randomised, double-blind, placebo-controlled, cross-over trial we enrolled patients with type 2 diabetes and persistent albuminuria (urinary albumin-to-creatinine ratio (UACR) > 30 mg/g) and estimated glomerular filtration rate (eGFR) ≥ 30 mL/min/1...

Abhishek Sharma, Sahil Agrawal, Sunny Goel, Jeffrey S Borer
PURPOSE OF REVIEW: Ischemic mitral regurgitation (MR), which occurs in about 20-30% patients with a prior myocardial infarction, is associated with worsening heart failure and an increase in cardiovascular mortality. It should be treated surgically if certain hemodynamic severity criteria are met and in patients who continue to experience symptoms of heart failure despite optimal medical therapy. However, current guidelines do not suggest which of the available approaches to mitral valve surgery-mitral valve (MV) repair or replacement (MVR) is superior for this indication...

BACKGROUND/AIMS: Subjective memory complaints (SMC) are strong predictors of mild cognitive impairment (MCI) and subsequent Alzheimer's disease. Our aims were to see if fully automated cerebral MR volume measurements could distinguish subjects with SMC and MCI from controls, and if probable parental late-onset Alzheimer's disease (LOAD), apolipoprotein E ε4 genotype, total plasma homocysteine, and cardiovascular risk factors were associated with MR volumetric findings. METHODS: 198 stroke-free subjects comprised the control (n = 58), the SMC (n = 25) and the MCI (n = 115) groups...

OBJECTIVE: Elevated aldosterone is associated with increased risk of atherosclerosis complications, whereas treatment with mineralocorticoid receptor (MR) antagonists decreases the rate of cardiovascular events. Here we test the hypothesis that aldosterone promotes early atherosclerosis by modulating intercellular adhesion molecule-1 (ICAM-1) expression and investigate the molecular mechanisms by which aldosterone regulates ICAM-1 expression. METHODS AND RESULTS: Apolipoprotein-E (ApoE)(-/-) mice fed an atherogenic diet and treated with aldosterone for 4weeks showed increased vascular expression of ICAM-1, paralleled by enhanced atherosclerotic plaque size in the aortic root...

Although a subtype of hypertrophic cardiomyopathy (HCM), dilated phase of HCM (D-HCM) characterized by left ventricular (LV) systolic dysfunction, has been reported to have a poor prognosis, some patients with D-HCM survive for a relatively long period. The degree of LV dilatation and functional mitral regurgitation (MR) are generally thought to be important predictors of poor prognosis in patients with LV systolic dysfunction. However, there is little information available on the relations among LV size, presence of significant MR, and prognosis in D-HCM patients...
