In patients with septic shock, oxidative stress was associated with mortality. On the other hand, thiamine was not associated with oxidative stress or mortality in these patients.

-Background -The nutritional status of individuals with inflammatory bowel diseases is directly related to the severity of the disease and is associated with poor prognosis and the deterioration of immune competence. Objective -To assess the nutritional status and the body composition of outpatients with inflammatory bowel diseases. Methods -A cross-sectional study was conducted with clinical and nutritional assessment of patients with Crohn's disease and ulcerative colitis. Patients were classified according to the clinical activity through Crohn's Disease Activity Index and Mayo Score. Nutritional assessment consisted of anthropometric measurements of current weight, height, mid-arm circumference, triceps skinfold thickness and thickness of adductor policis muscle, with subsequent calculation of BMI, arm muscle circumference and the mid-arm muscle area (MAMA

A large number of individuals showed an inadequate intake of nutrients. In addition, the consumption of vitamin D was significantly associated with extent of disease.

Objective: This article aims to discuss the role of nutrition therapy in Inflammatory Bowel Diseases according to its indications, contraindications, and the as main results obtained with prebiotics, probiotics, symbiotics and other nutritional interventions. Data source: We performed a literature review using the databases Pubmed, Scielo and Lilacs. Data synthesis: Inflammatory Bowel Diseases are chronic illnesses that affect primarily the gastrointestinal tract and are divided in two most common forms of presentation: Crohn's Disease and Ulcerative Colitis. The chronic inflammation can cause intestinal lesions, anorexia, nutrients malabsorption, oxidative stress and higher energy consumption, increasing the risk of malnutrition. Nutritional status is directly associated with the disease severity and malnutrition is a serious complication of inflammatory bowel diseases that worsens the patients' prognosis. Nutritional therapy is used to prevent or treat the malnutrition, to correct macro and micronutrients deficits and to reverse some of the metabolic and pathological consequences of these diseases. In the majority of patients, the nutrition therapy has an adjuvant role combined to medical or surgical treatments, but in some specific situations it can be the main treatment. Conclusions: Despite the benefits of nutritional therapy, more meta-analysis and double-blind controlled studies about these diseases are required to assure the good results obtained in some of the published trials.Objetivo: O objetivo do artigo é discutir o papel da Terapia Nutricional nas Doenças Inflamatórias Intestinais de acordo com suas indicações e contraindicações, bem como os principais resultados com prebióticos, probióticos, simbióticos e outras intervenções nutricionais nessas doenças. Fonte dos dados: Foi realizada busca por artigos nas bases de dados: Pubmed, Scielo e Lilacs. Síntese dos dados: Doenças Inflamatórias Intestinais são doenças crônicas que acometem principalmente o trato gastrointestinal e se dividem em duas formas mais comuns de apresentação: Doença de Crohn e Retocolite Ulcerativa. A inflamação crônica pode causar lesões intestinais, anorexia, má absorção de nutrientes, estresse oxidativo e aumento do gasto energético, aumentando o risco de desnutrição. O estado nutricional está diretamente associado com a gravidade da doença e a desnutrição é uma complicação que piora o prognóstico do paciente. A terapia nutricional é utilizada para impedir ou corrigir a desnutrição, repor deficiências de macro e micronutrientes e reverter parte das consequências metabólicas patológicas dessas doenças. Na maior parte dos pacientes, a terapia nutricional atua como coadjuvante combinada ao tratamento clínico ou cirúrgico, mas em algumas situações específicas pode ser o principal tratamento. Conclusão: Apesar dos vários benefícios atingidos pelo uso da terapia nutricional, mais metanálises e estudos randomizados duplo cegos ainda são necessários para comprovar os efeitos de suplementos específicos, garantindo, dessa maneira, resulta...

Handgrip strength may serve as an effective predictor of low lumbar spine T score among outpatients with cirrhosis. As cirrhosis affects the lumbar spine more than the femoral neck, these results suggest that handgrip strength should be tested in all patients with cirrhosis as a first indicator of bone health.
