Prognostic tools are available to identify individuals at high risk of osteoporotic fracture and assist physicians in management decisions. Some authors have suggested improving the predictive ability of current tools by integrating characteristics of prior fractures (number, location and time since prior fracture). The objectives of this study were i) to evaluate the sex-age-specific association between characteristics of prior fractures and the occurrence of a future osteoporotic fracture and ii) to assess whether the characteristics of prior fractures could increase the discriminative ability of fracture risk prediction tools...

BACKGROUND: Catheter ablation (CA) is a well-known treatment option for patients with symptomatic drug-resistant atrial fibrillation (AF). Multiple factors have been identified to determine AF recurrence after CA, however their predictive value is rather small. Identification of novel predictors of CA outcome is therefore of primary importance to reduce health costs and improve long-term results of this intervention. The recurrence of AF following CA is related to the severity of left ventricular (LV) dysfunction, extend of atrial dilatation and fibrosis...

Heart disease is the leading cause of hospitalization and death worldwide, severely affecting health care costs. Aging is a significant risk factor for heart disease and the senescent heart is characterized by structural and functional changes including diastolic and systolic dysfunction as well as left ventricular (LV) dyssynchrony. Speckle-tracking based strain echocardiography (STE) has been shown as a non-invasive, reproducible and highly sensitive methodology to evaluate LV function in both animal models and humans...

Speckle tracking echocardiography (STE) is increasingly used during functional assessments. However, reproducibility and dependence on echocardiographic image quality for speckle tracking stress echocardiography in pediatric patients have not been studied to date. 127 consecutive normotensive children without structural heart disease (mean age 13.4 ± 3.0 years, 50.4% female) underwent a stepwise semisupine cycle ergometric protocol. Left ventricular (LV) myocardial peak strain and strain rate were assessed at rest and during exercise...

BACKGROUND: Late after tetralogy of Fallot (TOF) repair some patients exhibit aortic dilatation and stiffness. Noninvasive assessment of aortic stiffness could contribute to understand this aortopathy and may be important in risk stratification for major aortic event. METHODS: We included prospectively 82 adults after TOF repair and 41 age- and sex-matched normal controls. Aortic diameters were measured by two-dimensional transthoracic echocardiography and the aortic z-score was estimated...

AIM: Left atrial (LA) fibrosis promotes atrial fibrillation (AF), may predict poor radiofrequency catheter ablation (RFCA) outcome, and may be assessed invasively using electroanatomical mapping (EAM). Speckle tracking echocardiography (STE) enables quantitative assessment of LA function. The aim was to assess the relationship between LA fibrosis derived from EAM and LA echocardiographic parameters as well as biomarkers of fibrosis in patients with AF. METHODS: Sixty-six patients (64% males, mean age 56 ± 10) with nonvalvular AF treated with first RFCA were prospectively studied...

Our aim in this study was to analyse the effects of early social isolation on the behaviour of a white-handed gibbon (Hylobates lar) and at the same time to improve his level of welfare. The subject was a 6-year-old male, isolated from conspecific as well as other non-human primates since he was 3 months old. We presented the gibbon with a series of species-specific vocalisations, and we then introduced a 23-year-old conspecific female into his cage. Our subject did not respond to playbacks, whereas he immediately interacted positively with the conspecific female...

BACKGROUND AND AIMS: Few studies have shown the direct effect of familial hypercholesterolemia (FH) on myocardial systolic function. Studies focused on heterozygote FH patients but not homozygote ones, and they did not perform genetic analyses. We aimed to evaluate all types of patients with FH using the potentially more sensitive speckle tracking echocardiography (STE) technique to identify early left ventricular (LV) dysfunction. METHODS: Genetic analyses of patients with FH were conducted for LDL-receptor, PCSK9, and ApoB100...
