Food consumption, physical activity and aerobic capacity in systemic lupus erythematosus patients with high cardiovascular risk

Abstract Systemic Lupus Erythematosus (SLE) is a chronic, autoimmune and multisystemic rheumatic disease. Patients with SLE have decreased functional and aerobic capacity, as well as increased prevalence of Cardiovascular Diseases (CVD), which are the primary causes of morbimortality in this condition. Dietary intake and physical activity are well-known modifiable cardiovascular risk factors. The aim of this study is to describe food consumption, sedentary behavior, physical activity level, and functional and aerobic capacity in a sample of SLE patients with high cardiovascular risk. This was a cross-sectional study in which patients were assessed for (i) Demographic, anthropometric, and disease-related parameters; (ii) Food consumption; (iii) Physical activity level and sedentary behavior; (iv) Functional and aerobic capacity. Patients averaged 41.7 ± 9 years, and most were classified as overweight/obese (87%). Average macronutrient intake was within recommendations; however, fiber (16 ± 9g) and calcium (391 ± 217 mg) intakes were below, and sodium intake (2.9 ± 1.3 mg) was above recommendations. Besides, food consumption assessed by the Nova system showed a predominance of unprocessed foods (43.8 ± 14.0%TEI), although ultraprocessed food intake (20.0 ± 13.9%TEI) was slightly higher than that seen in the Brazilian population. Patients also exhibited high sedentary behavior (8.2 ± 2.2h) and only eighteen participants reached the minimum recommended amount of moderate-to-vigorous physical activity. Overall, patients had a low functional and aerobic capacity compared to the general population. Data from this study may help design dedicated clinical trials aiming to investigate the effects of lifestyle intervention to mitigate CVD in SLE.

Principais motivos de internação do paciente com Insuficiência Renal Aguda na Unidade de Terapia Intensiva / Main Reasons of Patient’s Hospitalization with Acute Renal Failure in Intensive Care Unit

Esta pesquisa teve como objetivo identificar determinadas características de pacientes portadores de Insuficiência Renal Aguda (IRA) internados em uma Unidade de Terapia Intensiva (UTI) do Hospital de Base, bem como as causas de sua internação. Realizou-se uma análise retrospectiva de prontuários no período de 2002 a 2003. A avaliação dos resultados apontou que, 62% dos pacientes eram do sexo masculino; 42% tinham idade entre 61 e 80 anos; 21% desenvolveram IRA durante a internação; 81% das IRAs encontradas cursaram com oligúria, sendo que 84,4% eram de origem pré-renal; apenas 21% desses pacientes estudados receberam tratamento para IRA durante a internação; 33,8% permaneceram de um a cinco dias internados na UTI; 57,7% apresentaram hipertensão arterial como patologia de base; os problemas respiratórios foram prevalentes como diagnóstico inicial em 23,5% e os quadros de choque foram o principal motivo de internação em 22,9% dos pacientes e finalmente a mortalidade ocorreu em 58% dessa amostra.
