Sono e síndrome da fragilidade em idosos residentes em instituições de longa permanência

Introduction: The aging process causes quantitative and qualitative changes in sleeping. Such changes affects more than half of the adults above 65 years old, that live in the community and 70% of the institutionalized, a great negative impact in their quality of life. One of the pathological displays of aging, that share some characteristics with sleeping disorders and predict similar results, is the Frailty Syndrome, that characterize the most weakened and vulnerable elderly. The way sleeping disorders play a role in the frailty pathogeneses remains uncertain. Objective: Evaluate the relation between the sleeping and the frailty syndrome on institutionalized elderly. Methodology: A transversal study was performed with 69 elderly in institutions in the city of João Pessoa PB. Were used the Pittsburgh Sleeping Quality Index and actigraphy to subjective and objective variables, respectively, and questionnaires and specific tests to frailty phenotype variant (Fried Frailty Criteria). In the statistic analysis were used the Pearson correlation test, Chi Square and One-way ANOVA test, with Tukey-Krammer posttest. Subsequently, a Simple Linear Regression model was built. On every statistical analysis were considered a confidence interval of 95% and a p < 0,05. Results: The sample was characterized by the prevalence of the frail (49,3%), women (62,3%), single (50,7%) and 77,52 (±7,82).The frail elderly obtained the worst sleeping quality 10,37 (±4,31) (f = 4,15, p = 0,02), when compared with the non-frail. The sleep latency influenced more the frailty (R2 = 0,13, β standard = 1,76, β = 0,41, p = 0,001). Weren t found differences between the standard resting-activity variable and the frailty phenotype categories. Conclusion: Sleeping alterations, including bad sleeping quality, prolonged sleep latency, low sleep efficiency and day drowsiness, influenced the frailty in institutionalized elderly

Correlação entre os parâmetros do cortisol salivar e o fenótipo de fragilidade em idosos institucionalizados

Introduction: The Frailty Syndrome is characterized by the decrease of energy reserve and the reduced resistance to stressors. Studies indicate that the neuroendocrine markers can be related to the appearance of this syndrome. The main endocrine answer to stress is the increase of cortisol levels. Objective: To analyze the correlation between the frailty syndrome the salivary cortisol in elderly residing in nursing homes. Method: A traversal study was accomplished, in João Pessoa city, PB, with a sample composed by 69 institutionalized elderly. The collected data refer to the frailty phenotype (weight loss, exhaustion, slowness, weakness, and lower level of physical activity) and to salivary cortisol parameters (first measure - 6-7h; second measure - 11-12h; third measure - 16-17h). In the statistical analysis the Pearson s correlation test was used, Chi square Test and Anova and Simple Linear Regression analyses. Results: The sample was composed by 37.7% of men and 62.3% of women, with age average of 77.52 (±7.82). There was a percentile of 45.8% frail elderly. The frail elderly obtained higher cortisol values in the third measure (p=0.04) and the frailty load was significantly associated to the first measure (r=0.25, p=0.04). The simple linear regression analysis presented a determination rate (R2=0.05) between frailty load and first cortisol measure. Conclusion: The largest cortisol values in the morning and before sleeping among the frail elderly supply indications that can have a relationship of cortisol increase levels and the frailty presence in elderly from nursing homes.

Apoio social e síndrome da fragilidade em idosos residentes na comunidade

Introduction: The frailty in the elderly is the result of a complex interplay between many social and clinical factors involved in its genesis. Although there is an understanding of its association with increased risk of adverse clinical outcomes, still it is unclear whether this syndrome can be aggravated due to lack of social support. So, the objective of this study was to analyze the association between social support and frailty syndrome in elderly community residents. Materials and methods: Observational analytical cross-sectional study, with a sample of 300 elderly living in the city of Natal-RN. Were collected informations about socialdemographic, economics and physical health data. The Social support was assessed by the status of cohabitation; marital status; contact frequency and diversity rate; received and given attendance frequency rate; and Map Minimum Relations of the Elderly. The frailty was assessed using the following criteria: unintentional weight loss, weakness, low physical activity, exhaustion and Slowness. To observe any possible associations, we performed the Pearson chi-square test, the Student t test and multivariate analysis using binary logistic regression, adopting a significance level of 5%. Results: It was observed that there were no associations of frailty with the social support variables, except for housekeeping mode (p = 0.046) of the MMRI. For the sociodemographic, economic, physical health and social support data, only age (p <0.001), sedentary lifestyle (p = 0.002) and poor perceived health (p = 0.001) were the ones that remained in the logistic regression model, with strong association for the presence of frailty. Conclusion: Among the variables related to social support, only to help with housekeeping was significantly associated with frailty. However, more studies need to be developed to characterize the social vulnerability, as well as health services need to recognize the importance of social support as an integral part of care for the elderly

Validação da escala de fatigabilidade percebida para avaliação da fadiga em idosas

The term fatigability concerns the degree of fatigue associated with performing an activity of any type (physical, mental, emotional and / or social). Recently scales for assessing fatigue in the English language were created, however, gaps exist regarding the validity of these scales in relation to oxygen consumption and levels of perceived fatigue. Objective: To investigate the validity of perceived fatigability scale in older women frail and non-frail by the expired gases kinetics. Methods: This is a study of type validation, where were evaluated 48 elderly. The evaluation was conducted at two different sessions. In the first, data were collected demographic partners, as well as assessment of cognitive function, physical health, and the phenotype of frailty. The second was composed by the test 6-minute walk (6MWT) associated the expired gases kinects and assessment of perceived fatigability. Statistical analysis was performed a descriptive analysis and then we used the Pearson correlation test to evaluate the relationship between the measure of perceived fatigue and variables oxygen consumption (VO2), carbon dioxide production (VCO2), respiratory exchange ratio (RER)before and after 6MWT. We used a linear regression model initially considering the following explanatory variable: age, Body Mass Index (BMI), presence of frailty, comorbidities, level of physical activity, distance covered in the 6MWT , the energy cost of walking and severity of fatigability on performance. Results: The final sample consisted of 44 elderly women, 4 elderly were excluded because they didn t complete all phases of this study. The mean age obtained was 75 years (± 7.2 years). There was no significant correlation between fatigability measures and the values of VO2 ( r = .09 , p = .56 ) , VCO2 ( r = .173 , p = .26 ) , RER ( r = - .121 , p = .43 ). The final linear regression model showed that the energy cost of walking, the usual level of physical activity and the performance severity of fatigability explained 83.5 % (R2 = 0.835, p < 0.01) of the variation in the perceived fatigability. Conclusion: Our findings indicate a relationship between greater severity of fatigability and lower levels of physical activity and increased energy cost in walking, suggesting that the fatigability analyses using a simple numeric scale is valid and viable for assessment of fatigue in older women

Relationship between lower-limb muscle strength and frailty among elderly people

CONTEXTO E OBJETIVO: A sarcopenia é o principal fator envolvido no desenvolvimento da síndrome de fragilidade. O objetivo foi investigar a relação entre força muscular de membros inferiores e as variáveis sexo, idade e critérios de fragilidade; comparar a força muscular de membros inferiores com cada critério de fragilidade e verificar seu poder de estimativa do risco para fragilidade em idosos ambulatoriais. TIPO DE ESTUDO E LOCAL: Estudo transversal no Ambulatório de Geriatria de um hospital universitário de Campinas. MÉTODO: Foi avaliada uma amostra de conveniência não-probabilística de 150 idosos de ambos os sexos em acompanhamento ambulatorial, com coleta de dados sócio-demográficos (sexo e idade) e de saúde física (critérios de fragilidade e teste de levantar e sentar da cadeira cinco vezes consecutivamente). Foram realizadas análises descritivas, de comparação e de regressão logística multivariada. RESULTADOS: A maioria dos idosos (77,3%) apresentou idade igual ou superior a 70 anos, com predomínio do sexo feminino (64,0%) e baixo escore no teste de levantar e sentar da cadeira cinco vezes consecutivas (81,4% escore 0 ou 1), 55,3% dos idosos apresentaram três ou mais critérios de fragilidade. Verificou-se associação significativa entre a força muscular de membros inferiores e as variáveis idade e número de critérios de fragilidade. CONCLUSÕES: Menores níveis de força muscular de membros inferiores estão associados a idade avançada e maior presença de sinais de fragilidade. Além disso, a força muscular de membros inferiores também está associada com os critérios redução da velocidade de marcha e da força de preensão palmar.

Nesting behavior of the Picazuro Pigeon, Columba Picazuro (Columbidae, aves)

A pomba-asa-branca nidifica em todos os meses do ano no sudeste do Brasil. O material do ninho é quebrado dos ramos secos no tôpo de árvores ou pêgo no chão e levado para construir um ninho frágil e transparente onde será depositado um ovo. Fêmea e macho alternam-se na incubação e na criação do filhote e eles não sujam as bordas dos ninhos com fezes.

Prevalence of pre-frailty for the component of gait speed in older adults

OBJETIVO: investigar a pré-fragilidade e os fatores associados a essa condição, considerando as medidas de velocidade da marcha dos idosos. MÉTODO: a seleção dos participantes ocorreu por meio de critérios de inclusão/exclusão e teste de rastreamento cognitivo. A amostra foi calculada com base na estimativa da proporção populacional e constituída por 195 idosos, usuários de uma Unidade Básica de Saúde de Curitiba, PR. Os dados foram coletados mediante questionário sociodemográfico/clínico e teste de velocidade da marcha. RESULTADOS: a pré-fragilidade para velocidade da marcha possui moderada prevalência (27,3%) e associou-se à faixa etária entre 60 e 69 anos, baixa escolaridade, não se sentir solitário, utilizar anti-hipertensivo, apresentar doença cardiovascular e sobrepeso. CONCLUSÃO: considera-se relevante identificar os idosos na condição de pré-fragilidade, pois, dessa maneira, existe a possibilidade de intervenção imediata com a finalidade de estacionamento do quadro. É significativo o déficit de estudos sobre a síndrome da fragilidade em idosos brasileiros, principalmente aqueles que se referem a um componente isolado. Visto que a enfermagem gerontológica se encontra nos primeiros passos referentes à temática, entende-se que a identificação da prevalência deve ser o ponto primordial das pesquisas sobre o tema.

Influenza among the elderly in the Americas: A consensus statement

Influenza exacts a heavy burden on the elderly, a segment of the population that is estimated to experience rapid growth in the near future. In the past decade most developed and several developing countries have recommended influenza vaccination for those > 65 years of age. The World Health Organization (WHO) set a goal of 75% influenza vaccination coverage among the elderly by 2010, but it was not achieved. In 2011, the Technical Advisory Group at the Pan American Health Organization, Regional Office of WHO for the Americas, reiterated the influenza vaccine recommendation for older adults. Relatively little information has been compiled on the immunological aspect of aging or on reducing its impact, information particularly relevant for clinicians and gerontologist with firsthand experience confronting its effects. To fill this data gap, in 2012 the Americas Health Foundation (Washington, D.C., United States) and the nonprofit, Fighting Infectious Diseases in Emerging Countries (Miami, Florida, United States), convened a panel of Latin American clinicians and gerontologists with expertise in influenza to discuss key issues and develop a consensus statement. The major recommendations were to improve influenza surveillance throughout Latin America so that its impact can be quantified; and to conduct laboratory confirmation of influenza for all patients who have flu-like symptoms and are frail, immunosuppressed, have comorbidities, are respiratory compromised, or have been admitted to a hospital. The panel also noted that: since evidence for antivirals in the elderly is unclear, their use should be handled on a case-by-case basis; despite decreased immunological response, influenza vaccination in older adults is still crucial; indirect immunization strategies should be encouraged; and traditional infection control measures are essential in long-term care facilities.

Does proprioceptive system stimulation improve sit-to-walk performance in healthy young adults?

[Purpose] Sit-to-walk performance is linked to proper proprioceptive information processing. Therefore, it is believed that an increase of proprioceptive inflow (using muscle vibration) might improve sit-to-walk performance. However, before testing muscle vibration effects on a frail population, assessment of its effects on healthy young people is necessary. Thus, the aim of this study was to investigate the effects of muscle vibration on sit-to-walk performance in healthy young adults. [Subjects and Methods] Fifteen young adults performed the sit-to-walk task under three conditions: without vibration, with vibration applied before movement onset, and with vibration applied during the movement. Vibration was applied bilaterally for 30 s to the tibialis anterior, rectus femoris, and upper trapezius muscles bellies. The vibration parameters were as follows: 120 Hz and 1.2 mm. Kinematics and kinetic data were assessed using a 3D motion capture system and two force plates. The coordinates of reflective markers were used to define the center-of-mass velocities and displacements. In addition, the first step spatiotemporal variables were assessed. [Results] No vibration effect was observed on any dependent variables. [Conclusion] The results show that stimulation of the proprioceptive system with local muscle vibration does not improve sit-towalk performance in healthy young adults.

Percepção de acadêmicos de odontologia sobre o envelhecimento

The changes on learning space where Dentistry Students stay in front of social reality, by university extension, represent a strategy to form dentists according to Brazilian Curricular Directresses. In Araçatuba Dental School (FOA-UNESP), one of alternatives to add students on real locals of dentistry practices is the “Always Smiling Project – Dental Attention for institutionalized elderly in Araçatuba City, São Paulo State – Brazil”. The aim of this study was to verify the self-perception of dentistry students about aging before and after participation in this Project during one school year. To data collection, an instrument with 3 opened questions was performed and applied on 45 students, in the beginning of activities in 2009 and after 8 months. The answers were analyzed by content categorization. The results showed that the perception of students about old people was negative relating them with frail person that needs help and the students’ expectations were higher about clinical aspects of attention. In the end of school year was clear the difference of students’ comprehension about aging and their thoughts demonstrated the empathy resulting from relation. Besides, students related knowledge gain and noted that health attention involve others aspects that are over than biological space. It was possible to conclude that insertion of students in “Always Smiling” contributed to reflection and learn about aging process and suggest that practices like these should be added in Brazilian Universities.
