ABSTRACT
Resumo Estudo prospectivo e transversal, para determinar a prevalência de prejuízo cognitivo decorrente da quimioterapia e explorar fatores preditores e mediadores em sobreviventes de câncer de mama. Utilizou-se o Termômetro de Distress, Escala de Ansiedade e Depressão, Functional Assessment of Chronic Illness Therapy-General e Cognitive Function. As sobreviventes (N = 62) reportaram uma alta prevalência de distress (46,8%) e de ansiedade (24,2%), com baixos escores nas subescalas déficit cognitivo e habilidades cognitivas percebidos. O funcionamento cognitivo esteve associado à idade (β = 1,42; p = 0,002), atuação profissional (β = -23,12; p = 0,004), depressão (β = -5,43; p = 0,001) e qualidade de vida (β = 1,24; p = 0,001). Prejuízo cognitivo deve ser considerado no serviço de Psico-Oncologia.
Abstract Prospective and cross-sectional study to determine the prevalence of cognitive impairment resulting from chemotherapy, and to explore predictors and mediators in survivors of breast cancer. We used the Distress Thermometer, Hospital Anxiety and Depression Scale, Functional Assessment of Chronic Illness Therapy-General and Functional Assessment of Cancer Therapy-Cognitive Function. Survivors (N = 62) reported a high prevalence of distress (46.8%) and anxiety (24.2%), with low scores on cognitive deficit and cognitive skills perceived subscales. Cognitive functioning was associated with age (β = 1.42; p = 0.002), professional performance (β = -23.12; p = 0.004), depression (β = -5.43; p = 0.001), and quality of life (β = 1.24; p = 0.001). Cognitive impairment must be considered in Psycho-Oncology service.
ABSTRACT
A reduction of sleep time has become common over the last century, and growing evidence from both epidemiological and laboratory-based studies suggests sleep curtailment is a new risk factor for the development of obesity. On this basis, the present review examines the role of sleep curtailment in the metabolic and endocrine alterations, including decreased glucose tolerance and insulin sensitivity, increased evening concentrations of cortisol, increased levels of ghrelin, decreased levels of leptin and increased hunger and appetite. It will be discussed how sleep restriction may lead to increase in food intake and result in greater fatigue, which may favour decreased energy expenditure. Altogether, evidences point to a possible role of decreased sleep duration in the current epidemic of obesity and therefore present literature highlights the importance of getting enough good sleep for metabolic health. Many aspects still need to be clarified and intervention studies also need to be conducted.
