Estado nutricional e consumo alimentar de pacientes com psoríase dos tipos sistêmica e artropática sistêmica associada

OBJECTIVE: To identify the nutritional status and food intake of individuals with systemic psoriasis and psoriatic arthritis associated. METHODS: This is an exploratory and cross-sectional study with 34 men aged between 19 and 60 years seen at a Psoriasis Center. Participants were divided into systemic psoriasis group and arthritic-systemic psoriasis associated group. For nutritional assessment we used anthropometry, bioelectrical impedance analysis and whole-body plethysmography. Clinical and nutritional information were assessed using the clinical and nutritional history-taking, and the 24-hour dietary recall. For statistics the general linear model test (p < 0.05) was used. RESULTS: According to the body mass index 29.4% patients (n = 10) were eutrophic, 41.2% (n = 14) overweight and 29% (n = 10) obese. Almost all individuals (60%; n = 21) had body fat percentage above normal levels (> 25%) and a high risk for metabolic complications according to the waist circumference and the obesity index, however, there were no statistically significant differences between groups. The mean food intake, total fat, calories and protein were above recommended levels, being 58.8% for lipids (319.17 ± 241.02 mg of cholesterol and 17.42 ± 11.4 g saturated fatty acids); 29.4% for calories and 67.6% for proteins. Thus, regardless of the psoriasis type, an excessive consumption of calories, lipids, fatty acids, cholesterol and a higher incidence of overweight were found. CONCLUSION: The sample showed an abnormal nutritional condition, an increased risk for chronic diseases related to obesity, worsening of the psoriatic lesions, and poor quality of life.

Dano muscular: resposta inflamatória sistêmica após ações excêntricas máximas

O objetivo deste estudo foi analisar a resposta inflamatória induzida por grande número de ações excêntricas (AE) máximas realizadas pelos flexores do cotovelo. Participaram do estudo nove homens jovens, que realizaram 35 séries de seis AE nos flexores de cotovelo, com intervalo de um minuto, utilizando um dinamômetro isocinético em uma velocidade de 210º.s-1. As variáveis mensuradas foram: a contração isométrica voluntaria máxima (CIVM), a amplitude de movimento (AM), a dor muscular de inicio tardio (DMIT), a interleucina-6 (IL-6) e o fator de necrose tumoral alfa (TNF-α). Alterações significantes foram observadas para os marcadores indiretos de dano muscular (CIVM, AM e DMIT), entretanto não houve modificações para os marcadores inflamatórios (IL-6 e TNF-α). Em conclusão, os resultados demonstraram que mesmo com alterações nos marcadores indiretos de dano muscular após a realização de um grande número de AE não foram observadas alterações na resposta inflamatória sistêmica.
