RESUMO

BACKGROUND: Implementing cognitive assessment in older people admitted to hospital with hip fracture-lying in bed, experiencing pain-is challenging. We investigated the value of a quick and easy-to-administer 10-point Cognitive Screener (10-CS) in predicting 1-year functional recovery and survival after hip surgery. METHODS: Prospective cohort study comprising 304 older patients (mean age = 80.3 ± 9.1 years; women = 72%) with hip fracture consecutively admitted to a specialized academic medical center that supports secondary hospitals in Sao Paulo Metropolitan Area, Brazil. The 10-CS, a 2-minute bedside tool including temporal orientation, verbal fluency, and three-word recall, classified patients as having normal cognition, possible cognitive impairment, or probable cognitive impairment on admission. Outcomes were time-to-recovery activities of daily living (ADLs; Katz index) and mobility (New Mobility Score), and survival during 1-year after hip surgery. Hazard models, considering death as a competing risk, were used to associate the 10-CS categories with outcomes after adjusting for sociodemographic and clinical measures. RESULTS: On admission, 144 (47%) patients had probable cognitive impairment. Compared to those cognitively normal, patients with probable cognitive impairment presented less postsurgical recovery of ADLs (77% vs 40%; adjusted sub-hazard ratio [HR] = 0.44; 95% confidence interval [CI] = 0.32-0.62) and mobility (50% vs 30%; adjusted sub-HR = 0.52; 95% CI = 0.34-0.79), and higher risk of death (15% vs 40%; adjusted HR = 2.08; 95% CI = 1.03-4.20) over 1-year follow-up. CONCLUSIONS: The 10-CS is a strong predictor of functional recovery and survival after hip fracture repair. Cognitive assessment using quick and easy-to-administer screening tools like 10-CS can help clinicians make better decisions and offer tailored care for older patients admitted with hip fracture.

RESUMO

OBJECTIVE: To evaluate bone mineral density (BMD) and body composition over a six-year period in elderly long-distance runners. METHODS: We analyzed the medical records of elderly athletes who were long-distance runners, were participants of the IOT-HCFMUSP Orthogeriatric Group, and had their BMD evaluated between 2001 and 2007; of these athletes, 11 were included in the study. Inclusion criteria: athletes should be long-distance runners, should not stop long-distance running during the six-year period, and should have undergone BMD and body composition evaluations. Body composition was evaluated using bone densitometry with dual-energy X-ray absorptiometry with a Lunar-DPX device. RESULTS: Over the six-year period, body composition remained stable, but there was a significant increase only in the fat percentage (p = 0.003). CONCLUSION: Long-distance running may maintain BMD but may lead to an increase in the fat percentage in elderly runners. Level of Evidence II; Prognostic Study - Investigating the Effect of Patient Characteristics on Disease Outcome.

OBJETIVO: Acompanhar a densidade mineral óssea (DMO) e a composição corporal, ao longo de seis anos, em idosos corredores de longa distância. MÉTODOS: analisamos os prontuários médicos de um grupo de atletas idosos, corredores de longa distância, participantes do Grupo de Ortogeriatria do IOT-HC-FMUSP, e reunimos todos os atletas que tiveram a DMO avaliada no ano de 2001 e de 2007, sendo destes, 11 prontuários selecionados. Critérios de inclusão: ser corredor de longa distância; não parar de correr ao longo dos seis anos e ter os dois exames de DMO e composição corporal avaliados. A composição corporal foi avaliada por meio de densitometria óssea, com uma dupla energia de absorção de raios-X (DEXA), em um aparelho LUNAR-DPX. RESULTADOS: Ao longo dos seis anos, a composição corpórea se manteve estável, havendo apenas um aumento significante na gordura expressa em (%) (p=0,003). CONCLUSÃO: A corrida de longa distância parece conservar a DMO de idosos corredores, porém com aumento de gordura. Nível do Evidência II; Estudos prognósticos - Investigação do efeito de características de um paciente sobre o desfecho da doença.

RESUMO

OBJECTIVES: This study sought to analyze the extent of motor adaptation in ankle plantar flexors and dorsiflexors among older drivers during clinical isokinetic testing. METHODS: One hundred older adults (70.4±5.7 years) participated in two bilateral ankle plantar flexor and dorsiflexor isokinetic assessments at 30°/sec. Peak torque (PTQ), PTQ adjusted for body weight (PTQ/BW), and total work (TW) were analyzed. RESULTS: On the dominant side, PTQ/BW and TW were significantly greater for the second plantar flexion test than were those for the first such test (p<0.001), whereas PTQ, PTQ/BW, and TW (p<0.001) were significantly greater for the second dorsiflexion test than were those for the first such test. On the non-dominant side, plantar flexion PTQ and TW were significantly lower for the second test than were those for the first test (p<0.001). CONCLUSION: Older drivers demonstrated better performance with the dominant limb on the second test. The low variability in test execution showed the existence of a motor adaptation effect for the tested movements, despite the short recovery period between the assessments.

RESUMO

OBJECTIVE: To evaluate the association between bone mineral density (BMD) and body composition in healthy older adults at different skeletal sites. METHODS: We analyzed 87 medical records and BMD along with the body composition of men ranging from 60 to 87 years of age (mean: 68.5, standard deviation: 6.5). Inclusion criteria were normal BMD values (T-score greater than or equal to -1.0) and body mass index within normal or overweight range (18.5 to 29.5 kg/m2). Body composition was evaluated using bone densitometry with dual-energy X-ray absorptiometry (DEXA) in a LUNAR-DPX apparatus. RESULTS: Greater lean mass, fat mass, and soft tissue was associated with better BMD values in older adults, and higher age was associated with poorer BMD. CONCLUSION: Body composition (lean and fat masses and soft tissue) in older men is positively associated with BMD at all body sites (arms, legs, and trunk). Level of Evidence II; Prognostic studies - Investigating the effect of a patient characteristic on the outcome of disease.

OBJETIVO: Avaliar a associação entre a DMO e a composição corporal em idosos hígidos em diferentes sítios esqueléticos. MÉTODOS: Foram analisados 87 prontuários e exames de DMO com composição corporal de idosos do sexo masculino com média de idade de 68,5 (6,5) variando de 60 a 87 anos. Os critérios de inclusão foram valores de DMO dentro do normal (T-score maior ou igual a -1,0); IMC dentro dos valores normais ou sobrepeso (18,5 a 29,5 kg/m2). A composição corporal foi avaliada por meio de densitometria óssea por dupla emissão de raios-X (DEXA) em aparelho LUNAR-DPX. RESULTADOS: Quanto maior as massas magra e gorda e os tecidos moles, melhor os valores da DMO dos idosos e quanto maior a idade, pior a qualidade da DMO. CONCLUSÃO: A composição corporal (massas magra e gorda e tecidos moles) de homens idosos associa-se positivamente na DMO em todos os locais do corpo (membros superiores, inferiores e tronco).

RESUMO

The objective of the study was to examine the association between handgrip strength (HGS), knee flexion and extension strength, and static and dynamic balance in older women. One hundred and ten women with a mean age of 67.4±5.9 years were assessed for dynamic postural balance using the Time Up & Go Test (TUG) with and without cognitive tasks. Semi-static balance was assessed by means of a force platform; knee flexor and extensor muscle strength was calculated using an isokinetic dynamometer; and HGS using a hand held dynamometer. Weaker HGS was significantly correlated with worse performance in dynamic postural balance, as well as performance with TUG with and without cognitive tasks; however, there was no correlation between HGS and static balance. There was a moderate positive correlation between knee flexion/extension strength and HGS. This suggests that HGS could be used as a proxy indicator of overall strength capacity for clinical screening among older women.

RESUMO

OBJECTIVE: To compare Kendo players with active elderly adults in terms of quality of life, functional aspects (muscle strength, postural balance) and body composition. METHODS: This was a controlled cross-sectional study. Twenty elderly individuals were divided into two groups: the Kendo group, with an average age of 71.8 (5.4) years, and the Control group, with an average age of 73.1 (4.8) years. Quality of life was evaluated using a questionnaire (WHOQOL-bref and WHOQOL-old); body composition was evaluated with a bioimpedance scale (InBody230); hand-grip strength was assessed with a portable manual dynamometer (Jamar SH 5001); flexor and extensor muscle strength of the knees was evaluated with an isokinetic device (Biode® System 3 model Biodex Multi Joint System, BIODEX); and dynamic balance was assessed using a force platform (Balance Master System, Neurocom International, Inc.,® Clackamas County, Oregon, USA). RESULTS: The groups were statistically homogeneous in terms of socio-demographic characterization, body composition, muscle strength, and dynamic balance, but the Control group was faster in the sit-to-stand test (p=0.03). The Kendo group had a statistically significantly better quality of life; in the WHOQOL-bref, these differences were present in the physical (p≤0.001) and environment (p=0.004) domains, and in the WHOQOL-old, these differences were present in social participation (p=0.001) and in past, present, and future activities (p=0.019). CONCLUSION: The results suggest that Kendo is a health-promoting activity that improves the quality of life, functional aspects (muscle strength and postural balance) and body composition of players.
