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.

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.
