RESUMO
The aim of the study was to verify the effects of creatine (Cr) supplementation on functional capacity (walking capacity; primary outcome) and calf muscle oxygen saturation (StO2) (secondary outcome) in symptomatic peripheral arterial disease (PAD) patients. Twenty-nine patients, of both sexes, were randomized (1:1) in a double-blind manner for administration of placebo (PLA, n = 15) or creatine monohydrate (Cr, n = 14). The supplementation protocol consisted of 20 g/day for 1 week divided into four equal doses (loading phase), followed by single daily doses of 5 g in the subsequent 7 weeks (maintenance phase). Functional capacity (total walking distance) was assessed by the 6 min walk test, and calf muscle StO2 was assessed through near infrared spectroscopy. The measurements were collected before and after loading and after the maintenance phase. The level of significance was p < 0.05. No significant differences were found for function capacity (total walking distance (PLA: pre 389 ± 123 m vs. post loading 413 ± 131 m vs. post maintenance 382 ± 99 m; Cr: pre 373 ± 149 m vs. post loading 390 ± 115 m vs. post maintenance 369 ± 115 m, p = 0.170) and the calf muscle StO2 parameters (p > 0.05). Short- and long-term Cr supplementation does not influence functional capacity and calf muscle StO2 parameters in patients with symptomatic PAD.

A desnutrição é uma doença extremamente prevalente em pacientes internados, chegando a acometer 50% deles, 47% dos pacientes cirúrgicos e entre 39 e 73% dos portadores de doença arterial periférica, com grande impacto na morbimortalidade desses pacientes. A desnutrição possui grande relevância no desfecho clínico desses pacientes durante a internação, estando associada a maior incidência de infecções, demora na cicatrização das feridas, diminuição do status de deambulação, maior tempo de internação e mortalidade. Entretanto, o diagnóstico de desnutrição ou risco nutricional desses pacientes tem sido um desafio. A avaliação nutricional subjetiva global revelou-se, até o momento, o padrão ouro como método de triagem de pacientes cirúrgicos internados devido à sua praticidade e acurácia. O objetivo deste trabalho é revisar métodos utilizados na avaliação do estado nutricional e da triagem nutricional de pacientes internados e caracterizar a importância dessa avaliação nos desfechos clínicos dos pacientes com arteriopatias.
Malnutrition is an extremely common disease among hospitalized patients, with prevalence rates as high as 50% overall, 47% among surgical patients and from 39 to 73% among patients with peripheral arterial disease. It has a major impact on morbidity and mortality among these patients. Malnutrition is very relevant to these patients’ clinical outcomes and is associated with a higher incidence of infections, slower wound healing, lower rates of mobility, longer hospital stays and greater mortality. However, diagnosing malnutrition or nutritional risk in these patients has proven to be a challenge. To date, subjective global nutritional assessment remains the gold standard screening method for use with hospitalized surgical patients because of its practicality and accuracy. The objective of this study is to review methods used for assessment of nutritional status and for nutritional screening of hospitalized patients and determine the importance of these assessments to the clinical outcomes of patients with arteriopathies.

Peripheral arterial disease (PAD) is a significant cause of morbidity and mortality worldwide. Lifestyle changes, like the cessation of the use of tobacco as well as a modification of dietary and exercise habits, can be the most cost-effective interventions in patients with PAD. Smocking cessation is the most important intervention, since it increases survival in these patients. Antiplatelet therapy is an essential component in the treatment of peripheral arterial disease (PAD) of the lower extremities. In addition to delaying arterial obstructive progression, these agents are most usefull in reducing adverse cardiovascular events such as non-fatal myocardial infarction (MI), stroke and vascular death. Mainstay of treatment continues to be aspirin monotherapy (75-325mg daily). Current treatment for lower extremity PAD is directed towards the relief of symptoms and improvement in QoL. The two agents which have consistently been found to be most efficient in achieving these goals are cilostazol and naftidrofuryl oxalate. Naftidrofuryl oxalate may emerge as the most efficient and cost-effective treatment for symptom relief.
