ABSTRACT
SUMMARY Objective: to evaluate the relationship between levels of physical activity, fatigue and quality of life (QOL) in women diagnosed with breast cancer. Methods: 215 women between the ages of 40 and 65 years were recruited at a cancer clinic. Physical activity levels were assessed by using the International Physical Activity Questionnaire (IPAQ), fatigue levels by using the revised Piper scale, and QOL by means of EORTC QLQ-C30 and WHOQOL-Bref. Statistical analysis was performed using Minitab statistical software, version 16. Results: the mean age of subjects was 52.66 years (SD=8.6); patients were mostly white (58.14%) and overweight (55.81%). Most women were fatigued (72.09%) while physically active women showed lower symptoms of fatigue (p<0.001). Mean scores for QOL were significantly lower among fatigued women (p<0.001). More active women scored higher on all scales of QOL (EORTC), especially for functional capacity (p<0.001), compared with the sedentary patients. A significant association was found between level of physical activity and overall QOL (WHOQOL-Bref) for all domains (p<0.001). Climacteric symptoms ranged from mild to strong and did not show any statistically significant results; however, the most active women had the fewest symptoms. Conclusion: physical activity appears to positively influence fatigue and QOL in women diagnosed with breast cancer.
RESUMO Objetivo: avaliar a relação entre os níveis de atividade física, fadiga e qualidade de vida (QV) em mulheres diagnosticadas com câncer de mama. Métodos: foram selecionadas 215 mulheres com idades entre 40 e 65 anos selecionadas em um hospital de referência para tratamento de câncer de mama, no estado do Rio Grande do Norte, Brasil. Os níveis de atividade física foram avaliados por meio do Questionário Internacional de Atividade Física (IPAQ), a fadiga por meio da escala de Piper revisada, e a QV por meio do EORTC-QLQ-C30 e WHOQOL-Breaf. A análise estatística foi realizada utilizando o software estatístico Minitab, versão 16. Resultados: a idade média dos participantes foi de 52,66 anos (DP = 8,6), em sua maioria brancas (58,14%) e classificadas com sobrepeso (55,81%). Detectou-se alta prevalência de fadiga (72,09%), enquanto as mulheres fisicamente ativas apresentaram sintomas mais baixos de fadiga (p<0,001). Os escores médios de qualidade de vida foram significativamente menores para as mulheres sedentárias (p<0,001). Mulheres mais ativas apresentaram escores mais altos de QV (EORTC), principalmente na capacidade funcional (p<0,001), quando comparadas com as sedentárias. Foi encontrada uma associação significativa entre nível de atividade física e qualidade de vida global (WHOQOL-Bref) para todos os domínios (p<0,001). Sintomas climatéricos variaram de leve a forte intensidade e não apresentaram resultados estatisticamente significativos, porém as mulheres mais ativas apresentaram menor número de sintomas. Conclusão: Mulheres com níveis mais altos de atividade física apresentaram menos sintomas de fadiga e escores mais altos de qualidade de vida.

OBJECTIVE: To evaluate the effect of Chlamydia trachomatis infection during pregnancy on perinatal morbidity and mortality. METHODS: Systematic review and meta-analysis in an electronic database and manual, combining high sensitivity specific descriptors seeking to answer the research objective. The articles considered to be of high methodological quality (score above 6 on the Newcastle-Ottawa Scale) were assessed by meta-analysis. RESULTS: Summary estimates of 12 studies were calculated by means of Mantel-Haenszel test with 95 percent confidence interval. It was observed that Chlamydia infection during pregnancy increased risk of preterm labor (relative risk (RR) = 1.35 [1.11, 1.63]), low birth weight (RR = 1.52 [1.24, 1.87]) and perinatal mortality (RR = 1.84 [1.15, 2.94]). No evidence of increased risk was associated with Chlamydia infection in regard to premature rupture of membranes (RR = 1.13 [0.95, 1.34]), abortion and postpartum endometritis (RR = 1.20 [0.65, 2.20] and 0.89 [0.49, 1.61] respectively). CONCLUSION: The diagnosis and treatment of Chlamydia cervicitis during pregnancy can reduce perinatal morbidity and mortality associated with this infection. However, clinical trials are needed to confirm these findings.
