RESUMO
The study aimed to assess the regularity, intensity, frequency, and period of activities comprising social rhythm and associate them with the functionality of stroke patients. The sample consisted of 73 patients (41 men and 32 women) with a mean age of 60 years (±10). Social rhythm was assessed by Social Rhythm Metric (SRM) and Activity Level Index (ALI). The functionality was evaluated using the International Classification of Functioning, Disability, and Health (ICF). Data were analyzed using Student's t-test, ANOVA, and Chi-square test. The mean SRM was 5.1 ± 0.9, and ALI was 58.3 ± 14.9. Notably, 40% of the patients exhibited both low regularity and low intensity of activities. Six SRM activities, performed with low frequency (going outside, starting work, exercising, snacking, watching other TV programs, and going home), exhibited a tendency to have periods that deviated from the expected 24-hour daily cycle. ICF domains most associated with SRM were: d2-General tasks and demands, d3-Communication, d4-Mobility, d5-Self care, d8-Major life areas, and d9-Community, social and civic life. The results indicated changes in social rhythm with implications for patient functionality. Screening for disruptions in social rhythm could be part of the functional assessment during the rehabilitation process for post-stroke patients.
RESUMO
Objetivo. Estimar parámetros genéticos para la característica de productividad acumulada (PAC) y correlaciones genéticas con edad al primer parto (EPP), intervalo entre el primero y segundo parto (IEP1) y longevidad (LONG). Materiales y métodos. Fueron usados 8584 registros de hembras Brahman, utilizando un modelo animal en análisis multi-característico con el método de máxima verosimilitud restricta, implementado en el software WOMBAT. Los modelos consideraron los efectos fijos de grupo contemporáneo, número de partos, y la covariable peso al destete del primer ternero; el único efecto aleatorio fue el genético aditivo directo. El peso al destete (P240) fue incluido para disminuir el efecto de la selección en la estimación de los componentes de varianza. Resultados. Las estimativas de heredabilidad fueron de 0.3±0.04, 0.11±0.03, 0.07±0.03 y 0.24±0.04 para EPP, IEP1, LONG y PAC respectivamente. Las correlaciones entre PAC y las otras características se presentaron de moderadas a altas y en sentido favorable. Conclusiones. PAC puede ser incluida en los programas de mejoramiento genético para Brahman, y utilizada como criterio de selección por su heredabilidad moderada y correlación genética favorable con las características reproductivas en estudio.
Objective. Assessment of genetic parameters for accumulative productivity trait (ACP) and genetic correlations with age at first calving (AFC), between calving interval of first and second parity (BCI1) and longevity (LONG). Materials and methods. 8584 Brahman female records were used with an animal model in multi-trait analysis with restricted maximum likelihood method, implemented using the WOMBAT software. The models considered the fixed effects of contemporary group, parity and weaning weight of first calf covariate, the only random effect was the genetic additive direct. Weaning weight (P240) was included to reduce the effect of selection on the estimation of variance components. Results. The heritability estimates were 0.3±0.04, 0.11±0.03, 0.07±0.03 and 0.24±0.04 for AFC, BCI1, LONG and ACP respectively. Correlations between ACP and the other features were moderate to high and favorable. Conclusions. ACP can be included in breeding programs for Brahman, and used as selection criteria for its moderate heritability and genetic correlation with reproductive traits.
