Background: Diagnostic investigation of dementia is based on a series of tests which lie the neuropsychological evaluations. The Montreal Cognitive Assessment (MoCA) was developed as an instrument to recognize Mild Cognitive Impairment (MCI) and initial cases of Alzheimer’s disease. The present study aims to evaluate the predictive value of Brazilian MoCA test version in a sample of elderly above 5 years of education. Methods: Cross-sectional study with 136 elderly, above 60 years old at least 5 years of education. Diagnostic criteria is based on clinical and neuropsychological data classified Alzheimer’s disease n = 52, MCI n = 45 e normal controls n = 39. MoCA test was compared with Cambridge Cognitive Examination, Mini-Mental State Exam, Verbal Fluency, Clock Drawing Test, Geriatric Depression Scale and Pfeffer Functional Activities Questionnaire. Accuracy was evaluated by receiver operating characteristic (ROC) curve analyses. Pearson correlation coefficient was used to compare the MoCA with the other tests. It was also used logistic regression analysis to identify the main risk factors for the diagnostic groups. Results: MoCA was the best test to differentiate Alzheimer’s disease cases from MCI with 86.5% sensitivity and 75.6% specificity. Furthermore, analyzes of correlation test showed that MoCA correlates robust way of already validated with other tests and wide application inBrazil. Conclusions: It can be concluded that MoCA is a good screening tool for investigation of MCI among the elderly in Brazil with over 5 years of schooling. Studies with larger numbers of participants are needed to further validate the test also for elderly people with low education.

Research on cognitive aging is becoming increasingly common because aging is a global phenomenon and brings with it many challenges, for example, the increased incidence of dementias such as Alzheimer’s Disease (AD). Even if the cognitive decline in AD is apparently linear, impairment of autonomy in activities of daily living does not follow the same pattern. Objectives: To monitor and evaluate the cognitive aspects of elderly diagnosed with Alzheimer’s disease. Methodological procedures: This research was conducted from January 2006 to July 2013 at the Clinic of Geriatrics and Gerontology. Longitudinal study of 51 elderly patients aged 60 years, of both sexes who received a diagnosis of Alzheimer’s disease by DSM-IV (APA, 1994) and NINDS-ADRDA (McKhann et al., 2011). Results: From the results obtained in the present study, we observed that the participants had a decline in cognitive function from the first to the second assessment, even with drug treatment.

Abstract: The objective was to evaluate the forage mass production and quality in the morphologic components in different layers of coastcross grass (Cynodon dactylon [L.] Pers cv Coastcross-1) in consortium with forage Groundnut (Arachis pintoi Krapovikas y Gregory cv. Amarillo) with and without N fertilization. The treatments were: coastcross + forage groundnut without N (CA0); with 100kg/ha of N (CA100); with 200 kg/ha of N (CA200); and coastcross exclusively with 200kg/ha of N per year (C200) in the spring, summer and fall. It was used a randomized block design in a split plot. The layers were from zero to 7cm above the soil, 8 to 14cm, and above 15cm. In the lower layers there was higher total forage mass production. For the grass fractions there was no difference in the lower and higher layers however it was observed highter mass production with highest levels of fertilization. The senescent material was higher in fall. The intermediate layer showed superior values in the spring and fall compared to summer as a result of grazing in this layer be constituted of highest percentage of culms witch presented highest quality. The quality values were higher in treatments with nitrogen fertilization. Objetivou-se avaliar a massa de forragem e qualidade bromatológica dos componentes morfológicos nos diferentes estratos do pasto de coastcross (Cynodon dactylon [L.] Pers cv Coastcross-1) em consorcio com amendoim forrageiro (Arachis pintoi Krapovikas y Gregory cv Amarillo) com e sem utiliza o de N. Os tratamentos foram: coastcross + amendoim forrageiro sem nitrogênio (CA0); com 100kg/ha de N (CA100); com 200kg/ha de N (CA200) e coastcross exclusiva com 200kg/ha de N por ano (C200) na primavera, ver o e outono. Utilizou-se um delineamento em blocos casualizados em esquema de parcelas subdivididas. Os estratos foram de zero a 7cm a partir do solo, de 8 a 14cm e acima de 15cm. Nos estratos inferiores verificou-se maior MF. Para as fra es da gramínea n o houve diferen as nos estratos mais baixos e altos, porém nos tratamentos com maiores níveis de aduba o a massa de forragem foi superior. O material senescente foi superior no outono. O estrato intermediário apresentou valores superiores na primavera e outono comparados ao ver o, consequência do pastejo deste estrato estar constituído de maior percentagem de colmos. O valor nutritivo foi superior nos tratamentos que receberam aduba o nitrogenada.

Abstract: The trial was carried out to evaluate the alkanes (C27 to C35) profile, dry matter intake and digestibility of Coastcross-1 and Arachis pintoi mixed pasture with or without nitrogen fertilization in two periods (December/2003 and April/2004). The treatments evaluated were: CA0 = Coastcross + Arachis pintoi without N; CA100 = Coastcross + Arachis pintoi with 100 kg of N; CA200 = Coastcross + Arachis pintoi with 200 kg of N and C200 = Coastcross with 200 kg of N. The experimental period was composed by 8 days, with 3 days for marker administration (C32 in cellulose pelets) and 5 days for fecal collection, directly from animal rectum. Sixteen animals were used and maintained on grazed area since June 2003. From December to April, for pasture constituents, there was predominance of n-alkanes with odd chain, mainly for those with higher length chain (C29, C31 and C33), excepting leaves blade of Coastcross that presented the C27 alkane in higher concentration than C33. The highest amounts of n-alkanes C31 and C33 occurred during December. Animal’s intake and DMD did not present differences (P>0.05). The values of DMD using n-alkanes were similar to in vitro DMD of leaves blade from Coastcross. O experimento foi realizado com o objetivo de determinar o perfil dos alcanos (C27 a C35), o consumo e a digestibilidade da matéria seca do pasto de Coastcross-1 consorciada com Arachis pintoi com e sem aduba o nitrogenada em dois períodos (dezembro/2003 e abril/2004). Os tratamentos avaliados foram: CA0 = Coastcross + Arachis pintoi sem N; CA100 = Coastcross + Arachis pintoi com 100 Kg de N; CA200 = Coastcross + Arachis pintoi com 200 kg de N e C200 = Coastcross com 200 kg de N. O período experimental foi de 8 dias, 3 dias para o indicador administrado (C32 em peletes de celulose) e 5 dias de coleta de fezes, diretamente no reto do animal. Utilizou-se um delineamento em blocos ao acaso com duas repeti es. Foram utilizadas 16 novilhas cruzadas. Nos períodos de dezembro e abril, para os constituintes do pasto, houve predomínio dos n-alcanos de cadeia ímpar, principalmente para aqueles de maior comprimento de cadeia (C29, C31 e C33), exce o para as laminas foliares da Coastcross que apresentou o alcano C27 em maior concentra o do que o C33. As maiores quantidades de n-alcanos C31 e C33 ocorreram no mês de dezembro. O consumo dos animais e a digestibilidade do pasto n o apresentaram diferen as (P>0,05). Os valores dos CDMS, com utiliza o dos n-alcanos, foram semelhantes aos CDMS in vitro das laminas foliares da Coastcross

Abstract: the work was carried out to assess mass production and nutritional content of winter forages using lopsided oat (avena strigosa) and white oat (avena sativa) intercropped with ryegrass (lolium multiflorum) and vetch (vicia sativa l.). the species were intercropped as the following treatments: lopsided oat with ryegrass (lo+rg); white oat with ryegrass (co+rg); lopsided oat with vetch (lo+v); white oat with vetch (co+v); lopsided oat, vetch and ryegrass (lo+rg+v); and white oat, ryegrass and vetch (co+rg+v). the study evaluated total forage mass production of each intercropping and crude protein levels, neutral detergent fiber and in vitro digestibility coefficient of dry matter. the results indicate that forage yield of oats was higher in early assessments, and ryegrass and vetch were higher in the final evaluation period. the crude protein levels and neutral detergent fiber were higher at the start of the experiment for all evaluated treatments, and those including vetch intercropped with oats showed an increase in these parameters in the final period due to the presence of vetch, which has a more delayed cycle.
