    Minding your steps: a cross-sectional pilot study using foot-worn inertial sensors and dual-task gait analysis to assess the cognitive status of older adults with mobility limitati...

    BackgroundCognitive impairment is a critical aspect of our aging society. Yet, it receives inadequate intervention due to delayed or missed detection. Dual-task gait analysis is currently considered a solution to improve the early detection of cognitive impairment in clinical settings. Recently, our group proposed a new approach for the gait analysis resorting to inertial sensors placed on the shoes. This pilot study aimed to investigate the potential of this system to capture and differentiate gait performance in the presence of cognitive impairment based on single- and dual-task gait assessments.MethodsWe analyzed demographic and medical data, cognitive tests scores, physical tests scores, and gait metrics acquired from 29 older adults with mobility limitations. Gait metrics were extracted using the newly developed gait analysis approach and recorded in single- and dual-task conditions. Participants were stratified into two groups based on their Montreal Cognitive Assessment (MoCA) global cognitive scores. Statistical analysis was performed to assess differences between groups, discrimination ability, and association of gait metrics with cognitive performance.ResultsThe addition of the cognitive task influenced gait performance of both groups, but the effect was higher in the group with cognitive impairment. Multiple dual-task costs, dual-task variability, and dual-task asymmetry metrics presented significant differences between groups. Also, several of these metrics provided acceptable discrimination ability and had a significant association with MoCA scores. The dual-task effect on gait speed explained the highest percentage of the variance in MoCA scores. None of the single-task gait metrics presented significant differences between groups.ConclusionsOur preliminary results show that the newly developed gait analysis solution based on foot-worn inertial sensors is a pertinent tool to evaluate gait metrics affected by the cognitive status of older adults relying on single- and dual-task gait assessments. Further evaluation with a larger and more diverse group is required to establish system feasibility and reliability in clinical practice.

    Ciberjornalismo na lusofonia: contributo para um mapeamento

    Publication
    With this study we've intend to verify the extent to which online media (news websites) of Lusophone countries are harnessing the journalistic potential of Internet, and whether there are significant differences from country to country. We also wanted to know which capabilities are more and less used, and compare the results with those obtained in other studies based on the same methodology. As expected, the results show a lack of a single standard that features the Lusophone online journalism, as well as a clear divide between Iberia / Brazil, with higher levels of use of the potentialities of the Internet, and Africa, with the lowest values. These results suggest a direct relation between online journalism development levels in each country and the respective levels of economic development.

    The influence of metabolic profile of obese men on the severity of erectile dysfunction: Are metabolically healthy obese individuals protected?

    Publication
    Objective: To determine the prevalence of erectile dysfunction (ED) in metabolically healthy obese (MHO) individuals, and to compare ED severity and hypogonadism prevalence in MHO, metabolically unhealthy obese (MUO) and metabolically healthy non-obese individuals.Material and methods: ED patients (n=460) were evaluated by standardized protocol, that included clinical evaluation, abridged 5-item version of the International Index of Erectile Function (IIEF-5) questionnaire survey, and Penile Duplex Doppler Ultrasound (PDDU) exam. Patients were classified as obese [body mass index (BMI) =30.0 kg/m2] and non-obese (BMI <30.0 kg/m2), and metabolic health status was defined by National Cholesterol Education Program Adult Treatment Panel III (NCEP ATPIII) criteria. Statistical analysis was performed and statistical significance was considered at p-level <0.05.Results: The mean age of the subjects was 56.2±10.5 years. MHO was present in 40% of obese individuals (n=37). MUO had lower mean peak systolic velocity (mPSV) compared to MHO (28.1 cm/s vs. 36.9 cm/s; p=0.005), and IIEF-5 scores were also lower in MUO compared to MHO patients (10.2 vs. 13.1; p=0.018). No statistical differences in IIEF-5 score, mPSV and hypogonadism prevalence between MHO and metabolically healthy non-obese (MHNO) patients were observed.Conclusion: Our results lead us to conclude that healthy metabolic profile protects obese individuals from severity of ED. The strong association between obesity and ED may be otherwise attributed to metabolic abnormalities present in the obese.

    Risk Assessment of Tailings Disposal in a Portuguese Gold Mine Project. Contribution of Geostatistical Tools

    Publication
    The specific of the waste management of mining industry (landfills and tailings dams) impose the need of detailed closure and emergency plans, even in the pre-feasibility mine project. Risk management in mining waste disposal facilities implies policies aiming hazardous risk assessment as well as the implementation of mitigation and risk control programs. The present work is based on a case study involving the tailings dam of a Portuguese Gold Mine Project. A risk assessment considering an inventory of the different causes associated to a probability of a possible accident versus the severity of the consequences was established. As a result, different scenarios of rupture of the dam were established. Geostatistical tools were used to estimate and design flood maps in the event of collapse of the tailings dam. These flood maps allow not only an a priori evaluation of the areas eventually affected and the impact on neighbouring populations, but also constitute key elements in the implementation of emergency procedures that must accompany the life of the structure.
