NT-proBNP and Its Correlation with In-Hospital Mortality in the Very Elderly without an Admission Diagnosis of Heart Failure.

Background: The diagnosis of heart failure (HF) is often difficult and underestimated in very elderly comorbid patients, especially when an echocardiographic evaluation is not available or feasible.

Aim: to evaluate NT-proBNP values and their correlation with in-hospital mortality in a population of very elderly hospitalized for medical conditions other than HF.

Methods: We performed a prospective observational study on 403 very elderly admitted to an Internal Medicine and Geriatrics Department.

Efficacy of Non-Pharmacological Interventions to Prevent and Treat Delirium in Older Patients: A Systematic Overview. The SENATOR project ONTOP Series.

Background: Non-pharmacological intervention (e.g. multidisciplinary interventions, music therapy, bright light therapy, educational interventions etc.

Associations between body mass index, ambulatory blood pressure findings, and changes in cardiac structure: relevance of pulse and nighttime pressures.

Ambulatory blood pressure monitoring (ABPM) is central in the management of hypertension. Factors related to BP, such as body mass index (BMI), may differently affect particular aspects of 24-hour ABPM profiles. However, the relevance of BMI, the most used index of adiposity, has been underappreciated in the determination of specific aspects of 24-hour ABPM profiles in hypertension.

Circulating aldosterone and natriuretic peptides in the general community: relationship to cardiorenal and metabolic disease.

We sought to investigate the role of aldosterone as a mediator of disease and its relationship with the counter-regulatory natriuretic peptide (NP) system. We measured plasma aldosterone (n=1674; aged≥45 years old) in a random sample of the general population from Olmsted County, MN. In a multivariate logistic regression model, aldosterone analyzed as a continuous variable was associated with hypertension (odds ratio [OR]=1.

Hypertensive heart disease and obesity: a complex interaction between hemodynamic and not hemodynamic factors.

The worldwide prevalence of obesity has nearly doubled, with an increase in obesity-related cardiovascular disease and mortality. Several factors are involved in the genesis of hypertension and hypertensive heart disease (HHD) in overweight/obesity. This review is focused on bridging factors between excessive adiposity and HHD, presenting a unifying hypothesis of vascular-metabolic syndrome, where an "handicap" of the natriuretic peptide system has a central role both in adipocyte dysmetabolism as well as in increased blood pressure and HHD.

Chronic kidney disease is characterized by "double trouble" higher pulse pressure plus night-time systolic blood pressure and more severe cardiac damage.

Background: Hypertension plays a key role in chronic kidney disease (CKD), but CKD itself affects the blood pressure (BP) profile. The aim of this study was to assess the association of BP profile with CKD and the presence of cardiac organ damage.

Methods: We studied 1805 patients, referred to our Hypertension Centre, in whom ABPM, blood tests, and echocardiography were clinically indicated.

Nebivolol induces, via β3 adrenergic receptor, lipolysis, uncoupling protein 1, and reduction of lipid droplet size in human adipocytes.

Objectives: Most β-blockers may induce weight gain, dysglycemia, and dyslipidemia. Nebivolol is a third-generation β1-blocker with vasodilating properties mediated by β3 adrenergic receptors (β3AR). We investigated whether nebivolol is able to induce β3AR-mediated lipolysis, uncoupling protein 1 (UCP1), and size-reduction in human adipocytes.

Pattern of use and presenting complaints of older patients visiting an Emergency Department in Italy.

Background And Aims: The number of older persons admitted to the Emergency Department (ED) is dramatically increasing due to their complex medical and social problems, which in turn lead to longer clinical evaluation times and increased use of resources compared to younger adults. However, scant data are available for Italian EDs. Similarly, no data are available about the reasons to ED visit and its role in determining the ED utilization pattern.

Summer does not always mean lower: seasonality of 24 h, daytime, and night-time blood pressure.

Objective: Evaluation of seasonal influences on ambulatory blood pressure monitoring (ABPM) values in a very large population living in a mild-climate geographic area.

Methods: Among patients referred to our Hypertension Center between September 2002 and January 2011 with a reliable ABPM, we considered those in the two hottest (July and August) vs. those in the two coldest (January and February) months.

Plasma aldosterone is increased in class 2 and 3 obese essential hypertensive patients despite drug treatment.

Background: The aim of this study was to evaluate whether body mass index (BMI) is independently correlated with plasma aldosterone concentration (PAC) in treated essential hypertensive patients, and whether the relationship between BMI and high blood pressure (BP) can be partially mediated by PAC despite renin-angiotensin-aldosterone system blockade.

Methods: This study used a cross-sectional design and included 295 consecutive essential hypertensive patients referred to our centre for uncontrolled BP despite stable antihypertensive treatment for at least 6 months. The main exclusion criteria were age >65 years; glomerular filtration rate <30 ml/min; and therapy with mineralocorticoid receptor antagonists, direct renin inhibitors, amiloride or oral contraceptives.

Cardiac natriuretic peptides act via p38 MAPK to induce the brown fat thermogenic program in mouse and human adipocytes.

The ability of mammals to resist body fat accumulation is linked to their ability to expand the number and activity of "brown adipocytes" within white fat depots. Activation of β-adrenergic receptors (β-ARs) can induce a functional "brown-like" adipocyte phenotype. As cardiac natriuretic peptides (NPs) and β-AR agonists are similarly potent at stimulating lipolysis in human adipocytes, we investigated whether NPs could induce human and mouse adipocytes to acquire brown adipocyte features, including a capacity for thermogenic energy expenditure mediated by uncoupling protein 1 (UCP1).

Microalbuminuria and left ventricular mass in overweight and obese hypertensive patients: role of the metabolic syndrome.

Background: Left ventricular hypertrophy (LVH) and microalbuminuria are common in hypertensive patients and are often associated with metabolic syndrome (MetS). However, it is not clear whether MetS could modify the association between cardiac and renal damage.

Objective: The aim of this study was to assess if the relationship of albumin/creatinine ratio (ACR) and left ventricular mass (LVM) could be independent from MetS in hypertensive overweight/obese patients.

The association of left ventricular hypertrophy with metabolic syndrome is dependent on body mass index in hypertensive overweight or obese patients.

Background: Overweight (Ow) and obesity (Ob) influence blood pressure (BP) and left ventricular hypertrophy (LVH). It is unclear whether the presence of metabolic syndrome (MetS) independently affects echocardiographic parameters in hypertension.

Methods: 380 Ow/Ob essential hypertensive patients (age ≤ 65 years) presenting for referred BP control-related problems.

Cannabinoid CB1 receptor expression in relation to visceral adipose depots, endocannabinoid levels, microvascular damage, and the presence of the Cnr1 A3813G variant in humans.

Dysregulation of the endocannabinoid system in the visceral adipose tissue (VAT) is associated with metabolic and cardiovascular complications of obesity. We studied perirenal VAT CB1 receptor expression in relation to anthropometry, VAT area and endocannabinoid levels, kidney microvascular damage (MVDa), and the presence of the CB1 gene A3813G variant, the frequency of which was also evaluated in a large population of obese-hypertensive (OH) patients with or without the metabolic syndrome (MetS). Perirenal VAT and kidney samples were obtained from 30 patients undergoing renal surgery.

Predictive validity of the Identification of Seniors At Risk (ISAR) screening tool in elderly patients presenting to two Italian Emergency Departments.

Background And Aims: Elderly patients presenting to Emergency Departments (ED) have complex health problems and often undergo adverse outcomes after an ED visit. In Canadian ED, the Identification of Seniors At Risk (ISAR) is useful in screening for these aspects. This study evaluated the predictive validity of ISAR for elderly patients presenting to Italian ED.

Altered pattern of cannabinoid type 1 receptor expression in adipose tissue of dysmetabolic and overweight patients.

In overweight patients (OW), the increased peripheral activity of the endocannabinoid system in visceral adipose tissue (VAT) may be mediated by cannabinoid type 1 (CB1) receptor expression. We determined whether CB1 receptor splice variants and messenger RNA (mRNA) levels in perirenal and subcutaneous adipose tissues are associated with obesity and metabolic syndrome (MetS). Gene expression with multiple-primers real-time polymerase chain reaction (TaqMan; Applied Biosystem, Weiterstadt, Germany) was performed to study VAT and paired subcutaneous adipose tissue (SAT) mRNA from 36 consecutive patients undergoing nephrectomy.

A geriatric emergency service for acutely ill elderly patients: pattern of use and comparison with a conventional emergency department in Italy.

The current disease-oriented, episodic model of emergency care does not adequately address the complex needs of older adults presenting to emergency departments (EDs). Dedicated ED facilities with a specific organization (e.g.

Mini Nutritional Assessment (short form) and functional decline in older patients admitted to an acute medical ward.

Background And Aims: Protein and/or energy malnutrition is common in hospitalized older patients and is associated with poor outcomes. Among recommended nutritional screening tools, contrasting data exist about the usefulness of the Mini Nutritional Assessment Short-Form (MNA-SF). We evaluated whether the MNA-SF, alone or integrated with serum albumin levels, is a reliable predictor of functional decline in older patients.

A manual of guidelines to score the modified cumulative illness rating scale and its validation in acute hospitalized elderly patients.

Objectives: To update previous guidelines to score the Cumulative Illness Rating Scale (CIRS) and test their usefulness in hospitalized elderly patients.

Design: The CIRS was scored retrospectively in a cohort of elderly patients followed for 18 months.

Setting: An acute internal medicine ward in an academic tertiary care hospital.

A human fatty acid amide hydrolase (FAAH) functional gene variant is associated with lower blood pressure in young males.

Background: Fatty acid amide hydrolase (FAAH) inhibitors, preventing endocannabinoid (EC) degradation, reduce blood pressure (BP) and heart rate in young male (YM) hypertensive rodents. The functional human FAAH 129T gene variant results in reduced protein level and enzymatic activity but its relationship with BP is unknown. This study investigates the relationship among FAAH P129T alleles and cardiovascular features in YMs at baseline and after 9-year follow-up, and in older male obese hypertensive (OH) patients, in whom the EC system (ECS) is overactive.

Renin-angiotensin system, natriuretic peptides, obesity, metabolic syndrome, and hypertension: an integrated view in humans.

The obesity pandemic is closely related to hypertension and metabolic syndrome. Visceral adipose tissue plays a key role in the metabolic and cardiovascular complications of being overweight. The pathophysiological link between visceral adiposity and cardiometabolic complications focuses on insulin sensitivity, sympathetic nervous system, renin-angiotensin-aldosterone system (RAAS) and, only recently, on cardiac natriuretic peptide system (CNPS).
