Smartphone-based inertial measurements during Chester step test as a predictor of length of hospital stay in abdominopelvic cancer postoperative period: a prospective cohort study.

BACKGROUND: Objective assessment of pre-operative functional capacity in cancer patients using the smartphone gyroscope during the Chester step (CST) test may allow greater sensitivity of test results. This study has investigated whether the CST is a postoperative hospital permanence predictor in cancer patients undergoing abdominopelvic surgery through work, VO2MAX and gyroscopic movement analysis. METHODS: Prospective, quantitative, descriptive and inferential observational cohort study. Fifty-one patients were evaluated using CST in conjunction with a smartphone gyroscope. Multivariate linear regression analysis was used to examine the predictive value of the CST. RESULTS: The duration of hospital permanence 30 days after surgery was longer when patients who performed stage 1 showed lower RMS amplitude and higher peak power. The work increased as the test progressed in stage 3. High VO2MAX seemed to be a predictor of hospital permanence in those who completed levels 3 and 4 of the test. CONCLUSION: The use of the gyroscope was more accurate in detecting mobility changes, which predicted a less favorable result for those who met at level 1 of the CST. VO2MAX was a predictor of prolonged hospitalization from level 3 of the test. The work was less accurate to determine the patient's true functional capacity.

Impact of sociodemographic factors and screening, diagnosis, and treatment strategies on colorectal cancer mortality in Brazil: A 20-year ecological study.

Colorectal cancer (CRC) caused 261,060 deaths in Brazil over a 20-year period, with a tendency to increase over time. This study aimed to verify the sociodemographic factors predicting higher mortality caused by CRC and survival rates. Moreover, we aimed to verify whether the performance of screening, diagnostic and treatment procedures had an impact on mortality. Ecological observational study of mortality due to CRC was conducted in Brazil from 2000-2019. The adjustment variable was age, which was used to calculate the age-standardized mortality rate (ASMR). The exposure variables were number of deaths and ASMR. Outcome variables were age-period-cohort, race classification, marital status, geographic region, and screening, diagnostic, and treatment procedures. Age-period-cohort analysis was performed. ANOVA and Kruskal-Wallis test with post hoc tests were used to assess differences in race classification, marital status, and geographic region. Multinomial logistic regression was used to test for interaction among sociodemographic factors. Survival analysis included Kaplan-Meier plot and Cox regression analysis were performed. Multivariate linear regression was used to test prediction using screening, diagnosis, and treatment procedures. In Brazil, mortality from CRC increased after age 45 years. The highest adjusted mortality rates were found among white individuals and in the South of the country (p < 0.05). Single, married, and widowed northern and northeastern persons had a higher risk of death than legally separated southern persons (p < 0.05). Lower survival rates were observed in brown and legally separated individuals and residents from the North (p < 0.05). An increase in first-line chemotherapy and a decrease in second-line chemotherapy were associated with high mortality in the north (p<0.05). In the south, second-line chemotherapy and abdominoperineal rectal resection were associated with high mortality (p < 0.05). Regional differences in sociodemographic factors and clinical procedures can serve as guidelines for adjusting public health policies.

Métodos de exercícios físicos para pessoas idosas com Alzheimer e os fatores que dificultam a sua prática: uma revisão sistemática / Methods of physical exercise for older adults with Alzheimer's and the factors that hinder its practice: a systematic review

Resumo Objetivo Verificar o impacto da participação de programas de exercícios físicos em pessoas idosas com doença de Alzheimer (DA) e os fatores que comprometem a sua prática. Método Trata-se de uma revisão sistemática nas bases de dados United States National Library of Medicine (PubMed), Web of Science, Scopus, Biblioteca Scientific Electronic Library Online (SciELO); LILACS e Embase, a partir de 2014. Utilizaram-se as diretrizes do PRISMA - 2020 e a análise de risco de viés com o apoio da ferramenta Cochrane (RoB2). Resultados Foram incluídos onze estudos para análise qualitativa. O comprometimento da memória episódica ocasiona um declínio na DA e envolve uma complexidade de processos cognitivos contendo múltiplos aspectos do sistema neural Conclusão A depressão, a ansiedade e a dificuldade de compreensão são os principais fatores que comprometem a participação da pessoa idosa com Alzheimer aos exercícios com o propósito de estímulo físico, e são os principais preditores que dificultam o desenvolvimento perceptivo-motor. Os protocolos com exercícios combinados parecem favorecer melhor a função executiva no paciente com DA. A conscientização do exercício físico é fundamental desde o início dos tratamentos, com a sugestão de se priorizar melhorias na atenção das pessoas idosas com DA. As particularidades da relação entre as atividades da vida diária e a capacidade funcional do paciente com Alzheimer ainda correspondem a uma lacuna a ser explorada, assim como a prescrição de exercícios específicos que considerem tanto o grau de atenção quanto o nível da doença.

Abstract Objective To assess the impact of participation in physical exercise programs among older adults with Alzheimer's disease (AD) and the factors that compromise its practice. Method This study constitutes a systematic review conducted across the databases of the United States National Library of Medicine (PubMed), Web of Science, Scopus, Scientific Electronic Library Online (SciELO), LILACS, and Embase, starting from 2014. The PRISMA - 2020 guidelines were employed, alongside bias risk analysis supported by the Cochrane (RoB2) tool. Results Eleven studies were included for qualitative analysis. The impairment of episodic memory leads to a decline in AD and involves a complexity of cognitive processes encompassing multiple aspects of the neural system. Conclusion Depression, anxiety, and difficulty in comprehension are the primary factors that compromise the participation of older adults with Alzheimer's in exercises aimed at physical stimulation, and they are the main predictors hindering perceptual-motor development. Protocols involving combined exercises appear to better promote executive function in patients with AD. Awareness of physical exercise is fundamental from the outset of treatments, with the suggestion to prioritize improvements in attention for older adults with AD. The particularities of the relationship between activities of daily living and the functional capacity of Alzheimer's patients still represent a gap to be explored, as well as the prescription of specific exercises that consider both the level of attention and the stage of the disease.

A notação logarítmica como opção de registro objetivo da estesiometria: um estudo piloto / THE LOGARITHMIC NUMBER AS AN OPTION OF OBJECTIVE REGISTRATION OF ESTESIOMETRY: A PILOT STUDY

Introdução: A Avaliação objetiva é um valioso recurso na pesquisa. Contudo, o estesiômetro provê informações por cores. Objetivo: Apresentar a conversão logarítmica dos valores nominais do estesiômetro como opção representativa de registro na avaliação de prejuízo tátil. Método: Estudo Piloto aprovado com parecer nº 1.337. 714, realizado de agosto de 2018 a julho de 2019. Valores nominais (gF) dos monofilamentos do estesiômetro foram convertidos em logaritmo, o procedimento serviu para o registro e o acompanhamento de pacientes cerebrovasculares em reabilitação (n=13), comparado ao controle (n=10), para notações de qualidade, acurácia e poder de inferências dos dados na representação do estado tátil. Statistical analysis performed by the GraphPad Prism 6.0 Program. Resultados: As opções numéricas trabalhadas conseguem representar a percepção da sensibilidade tátil, sendo que a conversão em logaritmo demonstra objetividade, sensibilidade, coerência e consistência para gerar mais inferências. Conclusão: A notação logarítmica para registro da sensibilidade é uma opção versátil de análise e interpretação dos dados na pesquisa em reabilitação.
