Association of mitral annulus calcification, aortic valve calcification with carotid intima media thickness
BACKGROUND: Mitral annular calcification (MAC) and aortic annular calcification (AVC) may represent a manifestation of generalized atherosclerosis in the elederly. Alterations in vascular structure, as indexed by the intima media thickness (IMT), are also recognized as independent predictors of adverse cardiovascular outcomes. AIM: To examine the relationship between the degree of calcification at mitral and/or aortic valve annulus and large artery structure (thickness). METHODS: We evaluated 102 consecutive patients who underwent transthoracic echocardiography and carotid artery echoDoppler for various indications; variables measured were: systemic blood pressure (BP), pulse pressure (PP=SBP-DBP), body mass index (BMI), fasting glucose, total, HDL, LDL chlolesterol, triglycerides, cIMT. The patients were divided according to a grading of valvular/annular lesions independent scores based on acoustic densitometry: 1 = annular/valvular sclerosis/calcification absence; 2 = annular/valvular sclerosis; 3 = annular calcification; 4 = annular-valvular calcification; 5 = valvular calcification with no recognition of the leaflets. RESULTS: Patient score was the highest observed for either valvular/annulus. Mean cIMT increased linearly with increasing valvular calcification score, ranging from 3.9 ± 0.48 mm in controls to 12.9 ± 1.8 mm in those subjects scored 5 (p < 0.0001). In the first to fourth quartile of cIMT values the respective maximal percentual of score were: score 1: 76.1%, score 2: 70.1%, score 4: 54.3% and score 5: 69.5% (p > 0.0001). CONCLUSION: MAC and AVC score can identify subgroups of patients with different cIMT values which indicate different incidence and prevalence of systemic artery diseases. This data may confirm MAC-AVC as a useful important diagnostic parameter of systemic atherosclerotic disease
Transport Infrastructure Surveillance and Monitoring by Electromagnetic Sensing: The ISTIMES Project
The ISTIMES project, funded by the European Commission in the frame of a joint Call “ICT and Security” of the Seventh Framework Programme, is presented and preliminary research results are discussed. The main objective of the ISTIMES project is to design, assess and promote an Information and Communication Technologies (ICT)-based system, exploiting distributed and local sensors, for non-destructive electromagnetic monitoring of critical transport infrastructures. The integration of electromagnetic technologies with new ICT information and telecommunications systems enables remotely controlled monitoring and surveillance and real time data imaging of the critical transport infrastructures. The project exploits different non-invasive imaging technologies based on electromagnetic sensing (optic fiber sensors, Synthetic Aperture Radar satellite platform based, hyperspectral spectroscopy, Infrared thermography, Ground Penetrating Radar-, low-frequency geophysical techniques, Ground based systems for displacement monitoring). In this paper, we show the preliminary results arising from the GPR and infrared thermographic measurements carried out on the Musmeci bridge in Potenza, located in a highly seismic area of the Apennine chain (Southern Italy) and representing one of the test beds of the project

Sex Differences in Hypertension: A Question worth Asking?
Hypertension is a complex disorder involving multiple organ systems and the primarily modifiable risk factor for heart disease, which is the leading cause of death among both men and women in the World. Although both men and women develop hypertension, distinct gender differences in the incidence and severity of hypertension are well established where men have a higher incidence of hypertension compared with women of the same age until the sixth decade of life [1,2]. Despite gender differences in human hypertension, the treatment guidelines do not differ by gender [3]. Even if the causes of hypertension are complex and are related to genetic factors, lifestyle, diet structure, and environmental factors including air pollution [4], coupled with the potential determinants of hypertension, sex differences in hypertension-which exist in human populations-are attributed to both biological and behavioural factors. The biological factors include sex hormones, chromosomal differences, and other biological sex differences that are protective against hypertension in women. These factors become prominent in adolescence and persist through adulthood until women reach menopause. Behavioural risk factors for hypertension include high body mass index, smoking, and low physical activity
Hypertensive response to exercise and exercise training in hypertension: odd couple no more
Abstract The diagnostic and prognostic implication of exaggerated blood pressure response to exercise has been controversial, with opinions ranging from a benign process to a harbinger of potential cardiovascular morbidity. Nonetheless, lowering of blood pressure and prevention of hypertension is in first instance preferable by lifestyle changes, and many studies have shown the inverse association between physical activity level and the incidence of cardiovascular diseases suggesting low aerobic fitness as a strong predictor for future cardiovascular disease and all-cause mortality in both healthy and cardiovascular disease patients, including those with hypertension. Endothelial function, large artery stiffness and neurohormonal response are surely implicated both in the development of exaggerated blood pressure response to exercise and in the positive effect of physical exercise in the prevention and management of hypertension and cardiovascular disease in general. In their interesting and well documented review published in this issue Kim and Ha broadly described the possible pathophysiologic mechanisms of exaggerated blood pressure response to exercise and its clinical implications: in this regard, a very interesting issue could be represented by the role of exercise training. In fact, there is an the ample evidence in the literature that physical activity could positively affect endothelial function, arterial stiffness, neurohormonal response and finally blood pressure levels both in healthy men and in hypertensive patients and so should be considered a very important element in the prevention and management of cardiovascular disease
