- Age effects on EEG correlates of the Wisconsin Card Sorting TestPublication . Dias, NS; Ferreira, D; Reis, J; Jacinto, LR; Fernandes, L; Pinho, F; Festa, J; Pereira, M; Afonso, N; Santos, NC; Cerqueira, JJ; Sousa, NBody and brain undergo several changes with aging. One of the domains in which these changes are more remarkable relates with cognitive performance. In the present work, electroencephalogram (EEG) markers (power spectral density and spectral coherence) of age-related cognitive decline were sought whilst the subjects performed the Wisconsin Card Sorting Test (WCST). Considering the expected age-related cognitive deficits, WCST was applied to young, mid-age and elderly participants, and the theta and alpha frequency bands were analyzed. From the results herein presented, higher theta and alpha power were found to be associated with a good performance in the WCST of younger subjects. Additionally, higher theta and alpha coherence were also associated with good performance and were shown to decline with age and a decrease in alpha peak frequency seems to be associated with aging. Additionally, inter-hemispheric long-range coherences and parietal theta power were identified as age-independent EEG correlates of cognitive performance. In summary, these data reveals age-dependent as well as age-independent EEG correlates of cognitive performance that contribute to the understanding of brain aging and related cognitive deficits.
- Avaliação das Anomalias do Metabolismo da Glicose Após a Gravidez Complicada por Diabetes GestacionalPublication . Matos, C; Pereira, Mntroduction: Gestational Diabetes Mellitus (GDM) is associated with an increased risk of maternal Diabetes Mellitus (DM). Our objective was to analyse post-partum reclassification anomalies, and its relation with maternal history, pregnancy data and neonatal outcomes. Methods: Retrospective analysis of women with gestational diabetes between the year 2000 to 2007, aged from 16 to 45 years old; 47.2% had positive familiar history of DM and 9.1% had past history of GDM. Other maternal and gestational characteristics were collected; newborn weight and morbidity and reclassification results were evaluated. Statistical analysis was based on descriptive methods and Spearman correlation, Kruskal-Wallis, Mann-Whitney, Qui-square and Fisher tests, and multivariate analysis by logistic regression. Results: 424 women; 69.6% underwent reclassification; 6.1% were diagnosed impaired fasting glucose, 12.5% impaired glucose tolerance and 3.7% DM. A relation was established, between progression to impaired glucose metabolism and family history of diabetes, elevated BMI before pregnancy, earlier gestational age at diagnosis and need for insulin therapy. Discussion: Only elevated BMI before pregnancy seems to predict progression to altered glucose metabolism. Therefore, it is important to develop preventive strategies for obesity and be aware that every woman with GDM undergoes reclassification tests.

- Quality of life in elderly Portuguese war veterans with post-traumatic stress symptomsPublication . Pereira, MG; Machado, JC; Pereira, M; Lopes, C; Pedras, SBACKGROUND: Studies show that post-traumatic stress symptoms among Portuguese veterans who participated in Colonial War (1961-75) are high, even though 43 years have gone by since the end of the war. AIMS: This study analyzed the role of family type, personality traits, and social support as predictors of post-traumatic stress symptoms and quality of life in war veterans, and whether satisfaction with social support was a mediator between neuroticism/post-traumatic stress symptoms and quality of life. METHOD: A cross-sectional study was conducted including 230 war veterans with a mean age of 60 years (SD=3.82). RESULTS: Results indicated a high prevalence of post-traumatic stress symptoms as well as high neuroticism, 16.5 (SD=4.41); 81% of veterans presented high psychological distress, suggesting emotional disturbance and 71% belonged to extreme families (families with cohesion and adaptability problems). Results showed that age (β=-0.166, p<0.05), social support (β=-0.184, p<0.01), and neuroticism (β=0.325, p<0.001) predicted post-traumatic stress symptoms. Age, professional status, social support, post-traumatic stress symptoms, family type, neuroticism, and extroversion predicted different dimensions of quality of life. Finally, a path analysis showed that satisfaction with social support was a mediator in the relationship between neuroticism and quality of life (β=-0.066; p<0.01) and between post-traumatic stress symptoms and quality of life (β=-0.108; p<0.01). CONCLUSION: Four decades after the Colonial War have passed, there is still a high prevalence of post-traumatic stress symptoms. Screening elderly veterans who present post-traumatic stress symptoms, for the presence of neuroticism traits, and assessing family type and social support, should be a standard practice in health care services, especially in the oldest and those who are retired. Social support should be promoted in order to enhance quality of life in this population.
