In the field of cardiovascular diseases, elevated levels of serum uric acid (UA) reflect a marked activation of the xanthine oxidase pathway with increase in free radicals production; it is often associated with an inflammatory state, oxygen consumption and endothelial dysfunction. All these associations have been also confirmed in heart failure (HF) but the pathophysiological role of UA in this setting is not well understood. The aim of this study was to evaluate the prognostic role of UA in outpatients enrolled in the Italian Registry of Congestive Heart Failure (IN-CHF).All patients met the European Society of Cardiology (ESC) criteria for diagnosis of HF. We considered patients with complete clinical data and UA level available at the baseline and at 1-year follow-up. The study population was composed of 877 patients aged 63 ± 12 years. One-year mortality was 10.8% and dead patients had a higher level of UA than survivors (7.1 mg dl⁻¹ vs 6.6 mg dl⁻¹, p0.0207). In multivariable full model of analysis, UA did not result in an independent predictor of death in overall population, but only in patients with low body mass index (BMI) (≤22 kg m⁻²) (hazard ratio (HR): 2.38, 95% confidence interval (CI) 1.36-4.18). In this subgroup, a statistically significant gradual relationship between UA and survival was detected starting from values higher than 8 mg dl⁻¹.Elevated level of UA is not an independent predictor of mortality in chronic HF, but it markedly worsens outcome if associated with low level of BMI. This association is likely an indicator of chronic inflammatory and catabolic state.

sarcopenia is defined as a syndrome characterized by progressive and generalized loss of muscle mass and strength. The main cause of sarcopenia is the alteration of protein metabolism, in which the proteolytic processes are not accompanied by an appropriate protein synthesis and muscle cells lose progressively the sensitivity to the anabolic stimulus. The most rational approach to delay the progression of sarcopenia and counteract the anabolic resistance is proper nutrition. Meat contains biologically active compounds, such as creatine, carnitine, Conjugated Linoleic Acid (CLA) which have significant impacts upon human protein metabolism.we performed a narrative literature review to evaluate the till-now evidence regarding: 1. adequate intake of meat in elderly as a topic for prevention of sarcopenia; 2. the correct intake of biologically active compounds contain in meat, which have significant impacts upon human protein metabolism and so have beneficial effects on prevention of sarcopenia. This review included 62 eligible studies.the results demonstrated that in elderly the optimum diet therapy for the sarcopenia prevention and treatment, which must aim at achieving specific metabolic goals, must recommend the consumption of 113 g of meat (220 kcal; 30 g protein) five time a week.in a varied and balanced diet, for preventing sarcopenia, it is recommended to assume meat 4-5 times a week (white meat 2 times per week, lean red meat less than 2 times per week, processed meat less than 1 time per week), as suggested in the diet pyramid for elderly.Introducción: la sarcopenia se define como un síndrome caracterizado por la pérdida progresiva y generalizada de la masa muscular y de la fuerza. La principal causa de la sarcopenia es la alteración del metabolismo de las proteínas, en la que los procesos proteolíticos no van acompañados de una síntesis de proteínas y células musculares adecuadas, con lo que se pierde progresivamente la sensibilidad al estímulo anabólico. El enfoque más racional para retrasar la progresión de la sarcopenia y contrarrestar la resistencia anabólica es una nutrición adecuada. La carne contiene compuestos biológicamente activos, tales como creatina, carnitina y ácido linoleico conjugado (CLA) que tienen impactos significativos sobre el metabolismo de la proteína humana. Métodos: se realizó una revisión de la literatura narrativa para evaluar la evidencia hasta ahora, en relación con: 1. ingesta adecuada de carne en ancianos como prevención de la sarcopenia; 2. la ingesta correcta de compuestos biológicamente activos que contiene la carne, que tienen impactos significativos sobre el metabolismo de la proteína humana y para así obtener efectos beneficiosos en la prevención de la sarcopenia. Esta revisión incluyó 62 estudios elegibles. Resultados: los resultados demostraron que en personas de edad avanzada la terapia óptima con dieta para la prevención y tratamiento de la sarcopenia, que debe apuntar al logro de los objetivos metabólicos específicos, debe recomendar el consumo de 113 g de carne (220 kcal; 30 g de proteínas) cinco veces a la semana. Conclusión: en una dieta variada y equilibrada, para prevenir la sarcopenia, se recomienda consumir la carne 4-5 veces a la semana (carne blanca 2 veces por semana, carne roja magra menos de 2 veces por semana, carne procesada menos de 1 vez por semana), como se sugiere en la pirámide de la dieta para personas mayores.

This study sought to prospectively assess which factors were related to short-term worsening heart failure (HF) leading to or not to hospital admission, in long-term outpatients followed by cardiologists. The subsequent decision-making process was also analyzed. The study population consisted of 2,701 outpatients enrolled in the registry of the Italian Network on Congestive Heart Failure (IN-CHF) and followed by 133 cardiology centers (19% of all existing Italian cardiology centers). Clinical and follow-up data were collected by local trained clinicians; 215 patients (8%) had short-term decompensation (on average 2 months after the index outpatient visit). Multivariate analysis showed that previous hospitalization, long duration of symptoms, ischemic etiology, atrial fibrillation, higher functional class (New York Heart Association classification III to IV), higher heart rate, and low systolic blood pressure were independently associated with HF destabilization. Poor compliance (21%) and infection (12%) were the most frequent precipitating factors, but a precipitating factor was not identified in 40% of the patients. Poor compliance was more common in women, but no other clinical characteristics emerged as being related with a specific precipitating factor. Fifty-seven percent of the patients with a short-term recurrence of worsening HF required hospital admission; infusion treatment with inotropes and/or vasodilators was necessary in 19% of them. Long-term therapy was changed in 48% of the patients. Thus, in ambulatory HF patients, short-term worsening HF can be predicted according to the clinical characteristics on an outpatient basis. Nearly 1/3 of precipitating factors can be prevented. Patient education and avoidance of inappropriate treatment may reduce the number of relapses.

Objectives: The role of atrial fibrillation (AF) in older patients with heart failure (HF) is controversial because many variables seem to influence their outcome. We investigated the predictivity of AF in 3 age groups of outpatients with HF. Methods: We analyzed 8,178 outpatients enrolled in the Italian Network on Congestive Heart Failure Registry with HF diagnosed according to the European Society of Cardiology criteria. A trained cardiologist established the diagnosis of AF and HF at the entry visit at each center. We stratified the population into 3 age groups, as follows: group A, ≤65 years; group B, 66–75 years, and group C, >75 years. Results: Group A was composed of 4,261 patients, 683 with AF (16.0%); in group B there were 2,651 patients, 638 with AF (24.1%), and group C was composed of 1,266 patients, 412 with AF (32.5%). The 1-year mortality rate was higher in AF patients in all groups. In a multivariate model, AF remained an independent risk factor for death in groups A and B, but not in group C [group A: hazard ratio (HR) 1.42, 95% confidence interval (CI) 1.10–1.81; group B: HR 1.29, 95% CI 1.00–1.67; group C: HR 1.05, 95% CI 0.78–1.43]. Conclusion: The prevalence of AF increased with age and was associated with a higher mortality rate. However, AF independently predicted all-cause mortality only in patients aged ≤75 years.

Osteoporosis is one of the most difficult problems in the management of Chronic Juvenile Arthritis (JCA). The available data suggest that bone loss results from multifactorial processes which lead to bone degradation through the activation of osteoclasts. Biphosphonates are synthetic factors that, once localized on the surface of hydroxyapatite crystals, do not allow either the production or destruction of the crystals. This activity seems to be due to cytotoxicity against osteoclasts and to inhibition of prostaglandin E2 synthesis. There is some evidence that these drugs are effective in the treatment of osteoporosis in several diseases. In an attempt to reduce or prevent osteoporosis in children affected by JCA we started a trial with disodium clodronate, a type of biphosphonate. Thirteen patients were enrolled in the study: 7 received disodium clodronate and 6 acted as control subjects. Before starting the therapy and after one year we performed a CT scan to evaluate the mineral bone density in all patients. The mean bone density increased from a bone mineral content of 129 mg/cc before treatment to 134 mg/cc after treatment (8% increase); control patients passed from 123 mg/cc to 115 mg/cc (7% decrease) in the same period. Only one child stopped treatment because of gastrointestinal side effects. The small number of patients enrolled in the trial does not allow any definite conclusions to be drawn, but the data are interesting and worthy of further study.

We report a case of a patient with severe sustained hypertension associated with hypertensive crises. The administration of prazosin, 1 mg, resulted in a dramatic drop of blood pressure to 100/80 mmHg. Subsequent therapy with prazosin in conjunction with a β-blocker was consistently effective in maintaining blood pressure reduction, so that diagnostic procedures for pheochromocytoma could be performed and the patient could be adequately prepared for surgery

Endomyocardial biopsies from 97 normal donor hearts were examined. Morphometric analysis showed: mean myocyte diameter 22.21 +/- 6.93 mu, mean nuclear dimension 7.32 +/- 2.33 mu, mean nuclear/sarcoplasmic ratio 0.33 +/- 0.02. 31 biopsies showed enlarged myocytes (mean diameter 31.65 +/- 3.98 mu) with increased nuclear size (mean 10.45 +/- 1.39 mu), but preserved nuclear/sarcoplasmic ratio (mean 0.33 +/- 0.01). The mean age of these latter subjects was significantly higher. Endocardial thickness mean value was 17.73 +/- 4.58 mu, but in 28 cases the value exceeded the considered upper normal limit of 20 mu. Interstitial mononuclear cells were rare and randomly present. Interstitial fibrosis was observed in 15% and focal fibrosis in 27% of cases. Our results show that histology of biopsies from clinically normal hearts can widely vary, sometime overriding the pathologic boundaries. These apparently "benign" abnormalities should be kept in mind when specific pathologic substrates of cardiac diseases have to be defined.

We report two brothers, aged 22 and 34, affected by dilated cardiomyopathy. At the first examination both patients were in NYHA functional class I. Their echocardiograms showed dilated and hypokinetic ventricles. Their clinical condition remained stable for three years, during which the peripheral immunophenotyping of T-lymphocyte subsets showed T-helper/T-suppressor ratio values lower than normal (normal value for our laboratory = 1.64 +/- 0.53) due both to low T-helper and to high T-suppressor subsets. Subsequently, the clinical condition of both patients deteriorated, exercise tolerance decreased and echocardiographic ventricular diameters increased. T-helper/T-suppressor ratio progressively increased from the initial values of 0.8 and 0.42 to 2.5 and 2.24, respectively. A few months later, both patients died, one because of refractory heart failure and the other one suddenly. Histologic examination of myocardial tissue in one patient showed a diffuse necrotizing disease involving myocytes with focal lymphocyte infiltrates, granulation tissue and endocardial thrombosis. The reported data underline the importance of genetic and familial factors in the pathogenesis and evolution of dilated cardiomyopathies. The increasing T-helper/T-suppressor ratio value which matched the deterioration of the clinical status, is proposed as a useful evolutive and prognostic marker.

Guidelines for cardiovascular rehabilitation from different countries underline the importance of psychological factors in the achievement of improved clinical conditions and quality of life in patients with cardiovascular disease (CVD). Nevertheless, little research has been performed to identify the specific factors that greatly affect or foster patients' quality of life. The aim of the current study was to investigate the contribution of illness perceptions (IP) and self-efficacy beliefs (SE) on the impact exerted by illness severity on health and life satisfaction in patients with CVD undergoing a rehabilitation program. The study had a cross-sectional design and involved 116 patients (mean age = 65.6 years; SD = 10.0 years; 79.3 % men). Illness severity was measured in terms of left ventricular ejection fraction (LVEF) at the discharge from the cardiology department, whereas psychological factors were assessed one week later. The results showed no relationships among LVEF and the two indicators of health and life satisfaction; moreover, these two variables are differently influenced by IP and cardiac risk factors SE (χ2(1) = 0.96, p = n.s.). Findings provide important suggestions for the implementation of interventions aimed at bettering patients' quality of life, underlying the importance of working on IP and SE to improve levels of health and life satisfaction in patients with CVD. © 2012 Springer Science+Business Media Dordrecht.

Background: Many studies have investigated the relationships between cardiovascular diseases and patients' depression; nevertheless, few is still known as regard the impact of illness severity on depression and whether psychosocial variables mediate this association. Purpose: The aim of this study is to investigate the putative mediating role of illness representations, self-efficacy beliefs, and perceived social support on the relationship between illness severity and depression. Methods: A total of 75 consecutive patients with cardiovascular disease (80 % men; mean age=65.44, SD=10.20) were enrolled in an Italian hospital. Illness severity was measured in terms of left ventricular ejection fraction, whereas psychological factors were assessed using self-report questionnaires. Results: The relationship between left ventricular ejection fraction and depression was mediated by identity illness perception, self-efficacy beliefs in managing cardiac risk factors, and perceived social support. Conclusion: The treatment of depression in cardiovascular disease patients may therefore benefit from a psychological intervention focused on patients' illness representations, self-efficacy beliefs, and their perceived social support. © 2013 International Society of Behavioral Medicine.

The article examines a university course held in 1978 by the music critic Fedele d’Amico (Rome, 1912 - Rome, 1990) at the Faculty of Letters of the University of Rome La Sapienza. The course offers a reading of the twentieth century, through the analysis of the main movements and composers of the first half of the century, highlighting the historiographical method and the teacher’s critical positions. The historiographical method of Fedele d’Amico attempts to identify the dominant character of the twentieth century through a comparison with nineteenth-century music. This character resides, according to d’Amico, in the general tendency of 20th century composers to be «anti-nineteenth century», to mark the discontinuity with respect to the previous century. In the more radical experiences of modernity represented above all by expressionism, dodecaphony and the serial avant-garde of the Darmstadt mouvement, d’Amico underlines the destruction of the linguistic character of music which, according to him, is the foundation of understanding in musical listening. The author, emphasizing the reductionism of some of d’Amico’s statements, avoids a generic charge of conservatism by relating them to the crisis of modernism and to the spread, in the criticism of the arts during the seventies, of a new postmodern image of the twentieth century.

Life goals, personal values and individual well-being: an empirical study - People fell happier and more satisfied when they have the possibility to devote themselves to the achievement of their life-goals, the most important goals usually reflect high-priority values that function as life guides. Main aim of the present study, involving 240 Italian adults, was to investigate the relationships among personal values, life-goals, and individual wellbeing. We identified various types of people considering their personal values and life-goals; they were then compared on four well-being indicators: life satisfaction, self-esteem, optimism, and hedonic balance. The pursuit of "relational" life-goals, supported by universalism and benevolence values, promotes higher levels of self-esteem and life satisfaction.
