Contrasting evidence shows a possible association between serum uric acid (SUA) and cognitive function in elderly subjects. We aimed at evaluating the impact of circulating SUA levels on cognitive function in a cohort of pharmacologically untreated young elderly subjects. For this study, we selected 288 healthy young elderly participants from the historical cohort of the Brisighella Heart Study (M: 108, F: 180; mean age: 69 ± 6 years old). ⋯ In the multiple regression analysis, the only factors associated with the MMSE score were: age (B = -0.058, 95% CI -0.108, -0.009, p = 0.022), LDL-C (B = -0.639, 95% CI -0.912, -0.411, p = 0.034) and SUA (B = -0.527, 95% CI -0.709, -0.344, p = 0.022). Repeating the analysis by low or high SUA level (based on the gender specific SUA distribution 50th percentile), it appears that in subjects with a low SUA, cognitive decline is only associated with age, while in those with high SUA it is associated with LDL-C (OR 1.18, 95% CI 1.07-1.33, p = 0.019) and SBP (OR 1.02, 95% CI 1.001-1.048, p = 0.039). Our data demonstrate a positive association between circulating levels of uric acid and cognitive dysfunction in a sample of pharmacologically untreated young elderly subjects.

The importance of focused cardiac ultrasound (FCU) in Internal Medicine care has been recognized by the American Society of Echocardiography. The aim of this study was to test what realistic skill targets could be achieved in FCU, with a relatively short training (theoretical and practical) of 9 h offered to Internal Medicine certification board attending students, and if the addition of further 9 h of training could significantly improve the level of competence. ⋯ As concerns the interpretative skills, only pericardial effusion and visual estimation of global systolic function could be correctly identified, while ventricular enlargement and IVC prove to be more difficult to evaluate. This study supports incorporating FCU into Internal Medicine fellowship training programs, and should facilitate the design of other similar training courses.

The rapid technological evolution accomplished in noninvasive cardiac imaging techniques over the past few decades has provided physicians with a large armamentarium for the evaluation of patients with known or suspected coronary heart disease. Noninvasive assessment of coronary artery calcium or noninvasive coronary angiography may be performed using computed tomography or magnetic resonance imaging. ⋯ These techniques coupled with the development of dedicated image fusion software packages to merge data sets from different modalities have paved the way for hybrid imaging. This article provides a description of the available noninvasive imaging techniques in the assessment of coronary anatomy, myocardial perfusion, and cardiac function in patients with known or suspected coronary heart disease.
