title: MoCa predictive power in neuropsychological assessment of patients with dementia

description: This study aimed to correlate neuropsicometric tests in elderly over 4 years of schooling and assess MoCA accuracy in diagnosing Alzheimer's disease and mild cognitive impairment (MCI). It evaluated 136 elderly patients treated at the Institute of Geriatrics and Gerontology, from April 2010 to December 2012. The instruments used were the Mini-Mental State Examination (MMSE), Cambridge Cognitive Examination (CAMCOG), Clock Drawing Test (CDT), Verbal Fluency test, Geriatric Depression Scale, Pfeffer Functional Activities Questionnaire (PFAQ), and Montreal Cognitive Assessement (MoCA). ROC curve analysis was used to establish cutoffs and the Pearson correlation coefficient to compare the MoCA with the other tests. The results showed that the MoCA was the best test to differentiate Alzheimer's disease from MCI. The sensitivity and specificity found were 82.2% and 92.3%, respectively. The analysis of the correlation test showed that MoCA is strongly correlated with other tests already validated and wide applied in Brazil. The MoCA test showed the greatest predictive value to differentiate AD from MCI and also differ MCI from normal controls. Furthermore, MoCA was significantly correlated with the age variable and MMSE, CAMCOG, CDT, Verbal Fluency and PFAQ tests, instruments that are already validated and widely used in Brazil.

title: Acoustic parameters of voices of women in post-menopause

description: INTRODUCTION: Voice aging is characterized by changes caused by body aging, interfering with the vocal intonations, revealing states of soul and body. To investigate the vocal quality of postmenopausal women using objective parameters is important to foster research in this area, as well as assisting in improving the quality of life of this group. OBJECTIVE: To determine the acoustic parameters of the voice of women in post-menopause. METHOD: Quantitative cross-sectional study was conducted with 23 women in the postmenopausal period, using the Praat software 5.2.0. The parameters considered were fundamental frequency, jitter, shimmer, harmonic noise and spectrographic analysis. The sample consisted of women enrolled in the Open University of Third Age in Salvador-BA. Data analysis was descriptive, using percentages, and t test to check the relationship between increasing age and vocal worsening. RESULTS: In this sample, 13% had values below the fundamental frequency of 150Hz and 34% between 150 and 217Hz, demonstrating voice deepening. There was a statistically significant worsening of this related to increasing age parameter (p=0.02471). There was difference between the jitter and shimmer parameters according to increasing age, but without statistical significance. These acoustic parameters are related to changes in the vibratory pattern of the vocal folds (vibration cycle). A harmonic noise ratio was above 15.000 in all women, but also had lower values with increasing age, with no statistical significance. CONCLUSION: The observed changes in acoustic parameters show that postmenopausal women had changes in vocal patterns, which can lead to decreased quality of life. Therefore, it requires a closer look at the need of speech therapy in this group.

title: Grip strength and physical fitness: a predictive study with active elderly

description: INTRODUCTION: Evaluation of handgrip strength (HS) is a useful method for assessing overall muscle strength of old people. OBJECTIVE: To investigate the relationship between HS and the physical skills of old people practitioners of physical exercise, according to sex. METHODS: A descriptive study with 106 women and 30 man practicing physical exercises in a university extension program, which underwent a battery of Senior Fitness Test (lower limb strength, upper limbs strength, lower limbs flexibility, agility / dynamic balance, upper limb flexibility and aerobic endurance). HS was evaluated by a handgrip dynamometer. We used descriptive statistics (mean and standard deviation) and inferential U test of Mann Whitney tests for independent samples and simple linear regression. The significance level was 5%. RESULTS: The HS right and left was higher in men than in women (p &lt;0.001). It was observed that HS is a good predictor of upper limb strength (approximately 11.4%) and aerobic endurance (approximately 14.0%) in women, while in men, HS explains these skills (approximately 22.0% and 20.0%, respectively) and also the agility / dynamic balance (approximately 21.0%). CONCLUSIONS: We observed that, among elderly practicing physical exercises, HS better predicts only the variation of physical tests that perform well, which increases the power of explanation and prediction among men, as they had better performance in physical assessments.

title: eldBETA: A Large Eldercare-oriented Benchmark Database of SSVEP-BCI for the Aging Population

description: Global population aging poses an unprecedented challenge and calls for a rising effort in eldercare and healthcare. Steady-state visual evoked potential based brain-computer interface (SSVEP-BCI) boasts its high transfer rate and shows great promise in real-world applications to support aging. Public database is critically important for designing the SSVEP-BCI systems. However, the SSVEP-BCI database tailored for the elder is scarce in existing studies. Therefore, in this study, we present a large <strong>eld</strong>ercare-oriented <strong>BE</strong>nchmark database of SSVEP-BCI for <strong>T</strong>he <strong>A</strong>ging population (eldBETA). The eldBETA database consisted of the 64-channel electroencephalogram (EEG) from 100 elder subjects, each of whom performed seven blocks of 9-target SSVEP-BCI task. We expect that the eldBETA database would provide a substrate for the design and optimization of the BCI systems intended for the elders.

title: Relationship between the functional competence of episodic memory and the factors associated with functional independence of healthy elderly

description: OBJECTIVE: This study aimed to describe the relationship between the functional competence of episodic memory and its associations with functional independence of healthy elderly in the city of Juiz de Fora, Minas Gerais state, Brazil. METHODS: It is a cross-sectional, descriptive and exploratory research in which 60 healthy elderly comprised the final sample. To evaluate the functional capacity, the Index of Independence of Daily Living and the Lawton Instrumental Activities of Daily Living Scale were used. The episodic memory was assessed by a test of West & Thorn, adapted and validated for the Brazilian population by Yassuda, Lasca e Neri in 2005. Statistical analysis were performed using the 5.0 version of the statistical software Sphinx Léxica and Eureka. RESULTS: Statistically significant association between education level and performance in episodic memory task was found, as well as between the latter and three items of assessment scale of instrumental activities of daily living, although inconclusive. CONCLUSIONS: It is believed that these results are due to the fact that there are so many differences between researches with respect to methodology and the choice of instruments that evaluates both episodic memory and the erderly's functional capacity. Furthermore, the hypothesis that in healthy aging there is a capacity to face gradual losses in episodic memory and compensate them using other strategies and resources, should receive attention in further research.

title: Evaluation of balance, mobility and flexibility in active and sedentary elderly women

description: OBJECTIVES: To compare balance, mobility and flexibility in elderly women who do not practice physical exercises and who practice aerobic and resistance exercises. METHODS: Fifty-five women between 60 and 81 years were evaluated, divided in four groups based on reported physical activity in the 12 months prior to assessment: Non-Practitioners of Physical Exercise (NPEF; n=22), Practitioners of Aerobic and Resistance Physical Exercise (PEFAR; n=15), Practitioners of Resistance Physical Exercise (PEFR, n=9) and Practitioners of Aerobic Physical Exercises (PEFA, n=9). Balance evaluation was assessed using the Berg Balance Scale; mobility by the Timed Up and Go test and flexibility through the Sit and Reach test. Anova test and Kruskal-Wallis and Newman-Keuls tests were used for normal and non-normal data, respectively. Level of significance was (p&lt;0.05). RESULTS: It was observed that in the mobility test all groups practicing some form of physical activity showed significantly higher performance (p&lt;0.01) than the NPEF group. Flexibility analysis showed that the PEFA group had significantly higher values (p=0.002) when compared to other groups, which indicate better performance. Balance did not show significantly different among other groups (p=0.093). CONCLUSION: Elderly women who practice physical exercise, whether aerobic or resistance, have better mobility than the NPEF; and PEFA had better flexibility than NPEF and practitioners of other forms of physical exercise.

title: Self-perception of chewing ability in elderly

description: INTRODUCTION: Chewing plays an important role in food preparation and maintenance of muscle activity required for other functions of the stomatognathic system. In the elderly, this function may change due to structural, morphological and biochemical alterations. OBJECTIVE: To study the chewing ability in elderly listing the difficulties during mastication. METHODS: Observational cross-sectional study of elderly aged 60 years or older, receiving outpatient care at a university hospital. Data collection was conducted through a questionnaire containing questions regarding the power of the elderly and their chewing ability process. For purposes of comparison between some items of the protocol and chewing ability, the latter variable was dichotomized as "satisfactory" and "unsatisfactory". For these analyzes, Fisher's exact test was used, considering the significance level of 5%. RESULTS: The sample consisted of 30 participants with a mean age of 74.4 years (+9.1). There was high tooth loss, reflected in the high rate of elderly users of prostheses. Concerning the difficulties mentioned about chewing, 46.7% were unable to eat any food, 50% felt the need to drink fluids during meals; and foods that represented major difficulties in chewing were: meat (53.3%), fruits and raw vegetables (46.7%) and cereals (40%). Regarding self-perceived chewing ability, 53.3% said satisfactory and 46.6% unsatisfactory. There was a statistically significant relationship between "self-perceived chewing ability" and food associated with difficult chewing (p≤0.001). CONCLUSION: The self-reported chewing ability was mostly satisfactory and the hardest solid foods had greater difficulty in chewing.

title: Religiosity and health-related quality of life of elderly in a city in Bahia, Brazil

description: OBJECTIVE: To evaluate the dimensions of health-related quality of life in older adults and its relationship with organizational religious affiliation (ORA), non-organizational religious affiliation (NORA) and intrinsic religiosity (IR). METHOD: Cross-sectional study with quantitative approach, with a random sample of 82 elderly enrolled in the Family Health Strategy in Capoeiruçu, Cachoeira-BA, Brazil. RESULTS: The female dominated with 61.4%. The mean age was (71 ± 9.39). In the eight dimensions of quality of life, the score ranged from 64.3 to 77.3. ORA was 74.4%; NORA was 89.1. For questions about IR: feel the presence of God, act according to their beliefs and if they strive to live the religion in all aspects of life, percentages of 95%, 90.2% and 84.2% were respectively found. Using the chi-square test, it was found that the dimension "limitations due to emotional problems" received the greatest influence of ORA (X2= 11.539; p= 0.001; Cramer's V= 0.372), NORA (X2= 7.949; p= 0.005; Cramer's V= 0.309) and IR (X2= 5.126; p= 0.05; Cramer's V= 0.249). It was also found a positive influence on the limitations due to physical, bodily pain, general health, mental and social health. No association was found between religiosity and "functional capacity" and "vitality" dimensions. CONCLUSIONS: It is inferred that there is a positive association between religiosity in its three dimensions (ORA, NORA and IR) and health-related quality of life for the elderly.
