RESUMO

Measures of social cognition have now become central in neuropsychology, being essential for early and differential diagnoses, follow-up, and rehabilitation in a wide range of conditions. With the scientific world becoming increasingly interconnected, international neuropsychological and medical collaborations are burgeoning to tackle the global challenges that are mental health conditions. These initiatives commonly merge data across a diversity of populations and countries, while ignoring their specificity. OBJECTIVE: In this context, we aimed to estimate the influence of participants' nationality on social cognition evaluation. This issue is of particular importance as most cognitive tasks are developed in highly specific contexts, not representative of that encountered by the world's population. METHOD: Through a large international study across 18 sites, neuropsychologists assessed core aspects of social cognition in 587 participants from 12 countries using traditional and widely used tasks. RESULTS: Age, gender, and education were found to impact measures of mentalizing and emotion recognition. After controlling for these factors, differences between countries accounted for more than 20% of the variance on both measures. Importantly, it was possible to isolate participants' nationality from potential translation issues, which classically constitute a major limitation. CONCLUSIONS: Overall, these findings highlight the need for important methodological shifts to better represent social cognition in both fundamental research and clinical practice, especially within emerging international networks and consortia.

RESUMO

BACKGROUND: Left ventricular hypertrophy (LVH), as well as the geometry pattern of the left ventricle, is believed to be an independent risk factor for hypertension. The present study investigated the changes in left ventricular mass, diastolic function and geometry in hypertensive patients in a prospective 5-year follow-up in conjunction with an evaluation of the regularity and effectiveness of treatment. METHODS AND RESULTS: One hundred hypertensive patients older than 18 years were examined according to the study protocol, which included registration of weight, height, vital signs, and echocardiography. After 5 years a repeat examination was performed. Patients were divided into 3 groups according to blood pressure (BP) control: group 1 (n=32), no regular medication; group 2 (n=44), regular treatment but no target BP levels; group 3 (n=14), regular effective treatment. In group 1 an increase in LVH and worsening of diastolic function were observed; in group 2 LVH and isovolumetric relaxation time remained unchanged, while the early peak velocity/atrial peak velocity ratio decreased; in group 3 there was a significant decrease in LVH. The geometry pattern only changed in 21 (23%) patients. CONCLUSIONS: LVH can be successfully reversed in only hypertensive with adequate BP control. The remodeling pattern appears to be a stable characteristic of the patient and transformation of one pattern into another is infrequent.

RESUMO

The temperature dependence of the mean square displacement of the (57)Fe nuclei due to motion faster than 100 ns are measured by temperature-dependent Mössbauer spectroscopy for oxidized and reduced HiPIPs from Ectothiorhodospira halophila, Chromatium vinosum WT and a Cys77Ser mutant. The behaviour is interpretable in the frame of the general model of protein dynamics distinguishing two temperature intervals. The character of harmonic and quasi-diffusional modes in HiPIPs is discussed. Dynamic information obtained from Mössbauer spectroscopy and Fe K-edge EXAFS are compared. Structure dynamics of the iron-sulfur cluster in the partially unfolded reduced HiPIP from C. vinosum was investigated by Mössbauer spectroscopy and EXAFS, indicating an intact metal centre and a protein backbone with a largely collapsed secondary structure. The role of the cofactor during protein folding is discussed. Differences in the dynamics between the native protein and the molten globule are found at physiological temperatures only. The structure and dynamic behaviour of the [Fe(4)S(4)]Cys(3)Ser cluster in the Cys77Ser mutant of the HiPIP from C. vinosum are analysed. The temperature dependence of electron relaxation in oxidized HiPIPs is investigated by Mössbauer spectroscopy and analysed theoretically, considering spin-spin and spin-lattice relaxation. The latter consists of contributions from direct phonon bottleneck and Orbach mechanisms. The data agree with former pulsed EPR results. Orbach relaxation is interpreted as due to transitions between electronic isomers of oxidized HiPIPs. With this interpretation, the energetic difference between both isomers equals the energy gap estimated from the temperature dependence of the Orbach relaxation.
