The aging population calls for instruments to assess functional and cognitive impairment in the elderly, aiming to prevent conditions that affect functional abilities.ObjectiveTo verify the accuracy and reliability of the Pfeffer (FAQ) scale for the Brazilian elderly population and to evaluate the reliability and reproducibility of the translated version of the Pfeffer Questionnaire.MethodsThe Brazilian version of the FAQ was applied to 110 elderly divided into two groups. Both groups were assessed by two blinded investigators at baseline and again after 15 days. In order to verify the accuracy and reliability of the instrument, sensitivity and specificity measurements for the presence or absence of functional and cognitive decline were calculated for various cut-off points and the ROC curve. Intra and inter-examiner reliability were assessed using the Interclass Correlation Coefficient (ICC) and Bland-Altman plots.ResultsFor the occurrence of cognitive decline, the ROC curve yielded an area under the curve of 0.909 (95%CI of 0.845 to 0.972), sensitivity of 75.68% (95%CI of 93.52% to 100%) and specificity of 97.26%. For the occurrence of functional decline, the ROC curve yielded an area under the curve of 0.851 (95%CI of 64.52% to 87.33%) and specificity of 80.36% (95%CI of 69.95% to 90.76%). The ICC was excellent, with all values exceeding 0.75. On the Bland-Altman plot, intra-examiner agreement was good, with p>0.05consistently close to 0. A systematic difference was found for inter-examiner agreement.ConclusionThe Pfeffer Questionnaire is applicable in the Brazilian elderly population and showed reliability and reproducibility compared to the original test.

Objective: to describe the deleterious effects of prolonged bed rest on the body systems of the elderly. Method: an integrative-narrative review was carried out, with the following research question: What are the effects of prolonged bed rest on the body systems of the elderly? The PubMed and Virtual Health Library databases were searched with the following terms: "bed rest” and "elderly" with the Boolean operator “and”. Results: a total of 1,639 articles were found. After application of the established criteria, nine articles remained, and 20 were added to maintain the citation of the primary source, giving a total of 29 articles. Conclusion: the immobility associated with prolonged bed rest is detrimental to the health of the elderly, as it affects several systems, such as the cardiovascular, pulmonary, gastrointestinal, musculoskeletal and urinary systems, which may lead to the onset of diseases in addition to those that led to bed rest.

Journalists and policy analysts have highlighted the emergence of Brazil as a regional power. However, little attention has been paid to its foreign policy strategies. Brazil's rise to prominence in world politics represents the historical culmination of a foreign policy featuring two main strategies -persuasion and consensus building -both of which emphasise the use of soft power. We analyse four current foreign policy initiatives: the campaign for a permanent seat on the UNSC; the development of a nuclear submarine; Brazil's leadership of the UN peacekeeping mission in Haiti; and government support for Brazilian multinationals. We suggest a growing tension between these initiatives and the two strategies identified above. These initiatives reflect the view current among some policymakers that if Brazil is to rise as a global power it must play by the rules of great power politics.

O crescente uso de smartphones, aliado ao envelhecimento populacional, fez surgirem no mercado diversos aplicativos voltados para o público idoso. Diante dessa realidade, o objetivo do estudo aqui apresentado foi descrever os aplicativos direcionados à saúde e ao cuidado de idosos. Realizou-se uma busca de aplicativos em smartphones com sistema operacional Android e iOS. Os descritores utilizados na busca foram: 'idoso', 'saúde do idoso', 'envelhecimento', 'elderly' e 'salud de los ancianos'. Foram encontrados 25 aplicativos que abrangem três temas: saúde dos idosos, cuidado de idosos e informações sobre a saúde e o cuidado de idosos. Os aplicativos objetivam a prática de exercício físico, a prevenção ou detecção de quedas, a estimulação cognitiva, a busca de profissionais ou serviços, o auxílio ao cuidado de idosos e a divulgação de informações sobre saúde e sobre doenças e tratamentos. Esses recursos podem trazer grande contribuição à saúde e ao aperfeiçoamento do cuidado ao idoso, sendo um instrumento de monitoramento, informação e promoção de hábitos saudáveis.

Introduction. Sarcopenia is defined as the progressive loss of skeletal muscle mass, associated with aging. A multidisciplinary approach has been increasingly prioritized in elderly care. A technique that has been widely used by the seniors is acupuncture. Objectives. To analyse the effects of acupuncture in muscle strength and in inflammatory markers of older people with sarcopenia. Methods. The sample was composed by 53 elderly people, aged over 60 years. Inclusion criteria were as follows: male and female seniors, sedentary and who were not under acupuncture treatment during the survey period. Assessment of body composition, handgrip strength, and functional test and IL-6, IL-10, and TNF-α cytokines analyses were performed. After verification of the physical examination, the subjects were divided into two groups (sarcopenic and nonsarcopenic). The first group was then randomized (by drawing lot) to be further divided into two subgroups: G1, composed of sarcopenic elderly people who received acupuncture intervention, and G2, composed of sarcopenic elderly people who did not receive intervention. The nonsarcopenic elderly people composed the group 3 (G3) and did not receive acupuncture intervention. ANOVA Split Plot was performed for intergroup comparison. For intragroup evaluation, ANOVA was conducted for repeated measures. For the delta values, ANCOVA was performed with the pretest as covariant. A p<0.05 significance level was adopted. Results. 26 older people concluded the collections. There was no statistically significant difference between the G1 group and the other ones regarding the assessed variables (muscle mass, muscle strength, functionality, and inflammatory markers). Conclusion. The results allow us to infer that it is possible that the conducted intervention protocol has not produced any significant effects in the studied population. UTN number: RBR-8df2h4.

Error in measurement of a posture evaluation system is related to the digitalization, camera resolution and distance in relation to the volunteer studied, among others. These errors are summed up during the process and many of them are not possible to be avoided; however, they must be known and quantified. Objective: to quantify the error of the positions measured by SAPO (postural assessment software) in different experimental situations. Methods: 16 photos of a 1.40m tall articulated mannequin were taken at the anterior, posterior, right lateral and left lateral planes with 3.2 and 12.0 megapixels resolution cameras, at 3.0m and 5.0m from the model. To quantify the error, the differences between the measurements obtained by SAPO and the ones made directed on the mannequin were calculated. Results: the mean values of the horizontal, vertical, angular and distance measurements are close to zero; however, some angles were larger for the left and right measurements. The 3.2 megapixel digital camera located 3 m away showed the lowest error. The digitalization position is not influenced by the experience of the evaluators. Conclusion: SAPO is an accurate method for clinical use. Further studies are necessary to verify the effect of the position plane of the volunteer in relation to the camera, the effect of the relocation and the measurement palpation provided by the software.

Objective:To compare ideal PaO2 with PaO2 found, ideal PaO2/FiO2 of room air with the one found, and ideal FiO2 with FiO2 found in mechanically ventilated elderly patients.Methods:Cross-sectional study that evaluated elderly mechanically ventilated patients for at least 72 hours and who underwent three subsequent blood gas analyses.Results:The sample consisted of 48 elderly with mean age of 74.77±9.36 years. There was a significant difference between the ideal PaO2 and the one found (p<0.001), between FiO2 corrected and the offered one, and also between ideal PaO2/FiO2 of room air and the PaO2/FiO2 found (p<0,001).Conclusion:A significant increase was seen in PaO2 and FiO2 and in alterations of gas exchange by PaO2/FiO2 index than those found in normal parameters.
