“A systematic literature review was performed regarding the burden on mental health caregivers. The studies were selected from the Virtual Health Library – Biblioteca Virtual de Sa de (BVS), using the keyword caregiver burden. The main criteria for this study were: full-text articles published between 2000 and 2010, in Portuguese, English or

Spanish; indexed on the BVS databases; which investigated the burden of mental health caregivers, and had caregivers as the main subject. The analysis was performed considering the following: title, year of publication, objectives, methodological approach, instruments and main results. The analysis of 114 full-text articles showed the predominant p53 inhibitor objectives were the burden on

informal caregivers and the validation see more of psychometric scales, particularly the Zarit Scale. Some studies showed an association between high levels of burden, feelings of guilt and depressive symptoms. On the other hand, psycho-educational interventions were indicated as having a positive impact. This theme has a growing scientific interest and there is a need for deeper studies addressing formal caregivers.”
“PurposeTo study balanced steady-state free precession CINE phase-sensitive water-fat separation imaging in four cardiac imaging planes to determine the necessary phase correction and image artifacts particular to this technique. MethodsTen healthy volunteers and two subjects with known heart pathologies were studied with standard balanced steady-state free precession CINE imaging.

Water-only and fat-only images were calculated using sign detection of the real part of the complex image after phase correction with constant and linear terms. Phase correction values were determined using both manual and automated methods. Differences in phase correction values between imaging planes, cardiac phases, coil elements, automated image reconstruction parameters as well as artifact scores between the automated and manual methods were studied with statistical tests. ResultsWater-fat separation performed well in the heart after constant and linear phase correction. Both constant (p = 0.8) and linear x (p = 1) and y (p = 1) phase correction values did not vary significantly across cardiac phases, but CP-868596 cell line varied significantly among the coils (p smaller than 0.001) and imaging planes (p smaller than 0.001). False water-fat separation artifacts were most frequent in the chest/back and also were present at the mitral and aortic valves. ConclusionConstant and linear phase correction is necessary to provide consistent results in standard imaging planes using a balanced steady-state free precession water-fat separation postprocessing algorithm applied to standard cardiac CINE imaging.
