Effect of water consumption on weight loss: a systematic review.

Water intake has been proposed for weight loss; however, the evidence of its efficacy is limited. The aim of this study was to systematically review the randomized clinical trials that assessed the effect of water consumption on weight with a follow up ≥ 12 weeks. A systematic query-based search was performed on PubMed, EBSCO, and Cochrane Library to identify eligible records that quantitatively measured body weight change after interventions.

Mechanical deformation in adult patients with unrepaired aortic coarctation.

Aortic coarctation is a congenital heart disease that causes an increased left ventricular afterload, resulting in increased systolic parietal tension, compensatory hypertrophy, and left ventricular systolic and diastolic dysfunction. The speckle tracking is a new echocardiographic technique that allows the detection of subclinic left ventricular systolic dysfunction. The aim of this study was to detect early left ventricular dysfunction using mechanical deformation by echocardiography in adults with un-repaired aortic coarctation.

Objective: The aim of this study was to investigate the presence of early left ventricular (LV) systolic dysfunction in adult patients with aortic coarctation (AoCo) and systemic arterial hypertension (SAH) compared to systemic hypertensive patients without coarctation and healthy controls by speckle tracking.

Methods: Sixty-one subjects were studied, who attended consecutively to external consultation. All were submitted to clinical history, resting electrocardiogram, conventional echocardiogram and with Speckle Tracking.
