Avaliação do perfil hematológico (Eritrograma) de peixes-boi-da amazônia (Trichechus inunguis NATTERER, 1883) mantidos em Santarém-PA / Evaluation of the sérum hematological (Erythrogram) of amazon manfish (Trichechus inunguis NATTERER, 1883) maintained in Santarém- PA

O Trichechus inunguis (Natterer, 1883), mais conhecido como peixe-boi-da-amazônia, é o menor mamífero aquático da ordem Sirenia, endêmico em praticamente todo o território da bacia amazônica. Sua população foi drasticamente reduzida no período pré e pós-colonial pela exploração de gordura e couro, e atualmente está na lista dos animais ameaçados de extinção. No município de Santarém-Pará, e cidades vizinhas, os animais oriundos de resgates realizados por órgãos ambientais e Corpo de Bombeiros, são recebidos no Zoológico da Universidade da Amazônia (ZOOUNAMA), e permanecem em um projeto de 2 fases, composto por reabilitação e soltura. Uma das ferramentas de suporte na clinica de animais em fase de reabilitação é o hemograma, que, quando necessário, permite instituir uma conduta terapêutica imediata, monitora a sanidade dos indivíduos e contribui para otimizar o manejo desses sirênios de água doce cativos. Dessa forma, a presente pesquisa objetivou avaliar as variaveis hematologicas dos peixes-boi em fase de reabilitação mantidos no ZOUNAMA. Foram avaliados os hemogramas de 37 animais sendo separados por grupos de acordo com a faixa etária e o sexo dos animais. Foi definido como filhote os animais entre 1 a 24 meses (grupo 1), jovens, os animais entre 24 a 72 meses (grupo 2) e adultos, com idade a partir de 73 meses (grupo 3). Os resultados não revelaram diferenças significativas (p>0,05) nos parametros hematologicos dos grupos avaliados no presnte estudo. Também foi constatado que as variaveis sanguineas se mantiveram dentro dos valores de referencia para a especie

Mild cognitive impairment is associated with poor physical function but not bone structure or density in late adulthood:Findings from the Hertfordshire Cohort Study

Mini Abstract This study investigated the association between mild cognitive impairment (MCI) and physical function and bone health in older adults. MCI was associated with poor physical performance but not bone mineral density or bone microarchitecture. Abstract Purpose: Cross-sectional study to investigate the association between mild cognitive impairment (MCI) and physical performance, and bone health, in a community-dwelling cohort of older adults. Methods: Cognitive function of 222 men and 221 women (mean age 75.5 and 75.8 years in men and women, respectively) was assessed by the Strawbridge questionnaire and Mini Mental State Exam (MMSE). Participants underwent dual-energy x-ray absorptiometry (DXA), peripheral-quantitative computed tomography (pQCT) and high-resolution peripheral-quantitative computed tomography (HR-pQCT) scans to assess their bone density, strength and microarchitecture. Their physical function was assessed and a physical performance (PP) score was recorded. Results: 11.8% of women and 8.1% of men in the study were cognitive impaired on the MMSE (score<24). 24% of women were deemed cognitively impaired on the Strawbridge questionnaire, compared to 22.3% of men. Cognitive impairment on the Strawbridge questionnaire was associated with poorer physical performance score in men but not women in the unadjusted analysis. MMSE <24 was strongly associated with the risk of low physical performance in men (OR 12.9, 95% CI 1.67, 99.8, p=0.01) Higher MMSE score was associated with better physical performance in both sexes. Poorer cognitive function, whether assessed by the Strawbridge questionnaire, or by MMSE score, was not associated with bone density, shape or microarchitecture, in either sex. Conclusion: MCI in older adults was associated with poor physical performance, but not bone density, shape or microarchitecture

Fall risk and function in older women after gynecologic surgery

Purpose of study: To examine change in balance-related fall risk and daily functional abilities in the first 2 postoperative weeks and up to 6 weeks after gynecologic surgery. Materials and methods: Prospective cohort study in gynecologic surgery patients age 65 and older. Balance confidence (Activities-specific Balance Confidence Scale) and functional status (basic and instrumental activities of daily living) were recorded pre-and post-operatively daily for 1 week and twice the second week. Physical performance balance and functional mobility were measured pre-and 1 week post-operatively using the Tinetti Fall Risk Scale, Timed Up and Go, and 6-Minute Walk test. Measures were repeated 6 weeks after surgery. Nonparametric tests for paired data were used comparing scores baseline to post-operative (POD) 7 and to POD 42. Results: Median age was 72 years (range 65-88). Fall risk was elevated during the first 2 post-operative weeks, greatest on the median discharge day, POD 2 (p < 0.01). Balance performance and functional mobility at 1 week were significantly lower than baseline (p < 0.01). Functional abilities declined, including new dependence in medication management at home in 22% of these independent and cognitively intact women. Conclusions: After gynecologic surgery, older women's fall risk is highest on POD 2 and remains elevated from baseline for 2 weeks. Functional limitations in the early home recovery period include the anticipated (bathing, cooking, etc.) and some unanticipated (medication management) ones. This information may help with postoperative discharge planning.Published open access.This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
