Abstract
Oxidative damage induced by ethanol and its metabolites is one of the factors that fuels the development of alcoholic liver disease (ALD). Selenium (Se) is an effective cofactor for glutathione peroxidase (GPx), and has antioxidant effects that improve ALD. In patients with ALD, ethanol-induced oxidative damage inhibits the synthesis of related Se-containing proteins such as: selenoprotein P (Sepp1), albumin (ALB), and GPx in the liver, thus decreasing the overall Se level in patients. Both Se deficiency and excess can affect the expression of GPx, resulting in damage to the antioxidant defense system. This damage enhances oxidative stress by increasing the levels of reactive oxygen species (ROS) in the body, which aggravates the inflammatory response, lipid metabolism disorder, and lipid peroxidation and worsens ALD symptoms. A cascade of oxidative damages caused by ALD will deplete selenium deposition in the body, stimulate the expression of Gpx1, Sepp1, and Gpx4, and thus mobilize systemic selenoproteins, which can restore GPx activity in the hepatocytes of ALD patients, reduce the levels of reactive oxygen species and alleviate oxidative stress, the inflammatory response, lipid metabolism disorder, and lipid peroxidation, thus helping to mitigate ALD. This review provides a reference for future ALD studies that evaluate the regulation of Se levels and contributes to studies on the potential pathological mechanisms of Se imbalance in ALD.

Abstract
BACKGROUND It is well known that alcohol can trigger inflammatory effects in the gastrointestinal tract (GIT) interfering with mucosal homeostasis. OBJECTIVE This study evaluated the effectiveness of Lactococcus lactis treatment in controlling the increase in molecular biomarkers related to allergic inflammation, and the effect on the diversity and abundance of the Enterobacteriaceae family in the GIT after high-dose acute administration of ethanol. METHODS Mice received ethanol or saline solution by gavage for four consecutive days, and 24 h after the last administration the animals were given L. lactis or M17 broth orally ad libitum for two consecutive days. The animals were subsequently sacrificed and dissected. RESULTS L. lactis treatment was able to restore basal levels of secretory immunoglobulin A in the gastric mucosa, serum total immunoglobulin E, interleukin (IL)-4 production in gastric and intestinal tissues, and IL-10 levels in gastric tissue. L. lactis treatment encouraged the diversification of the Enterobacteriaceae population, particularly the commensal species, in the GIT. CONCLUSION This research opens a field of studies regarding the modulatory effect of L. lactis on immunological and microbial changes induced after alcohol intake.

Abstract
INTRODUCTION Sideroblastic anemia is a rare cause of microcytic anemia, which is characterized by ring sideroblasts on bone marrow aspirate. This anemia can be congenital or acquired. CASE REPORT We report the case of an alcoholic 49-year-old man who presented with a severe microcytic sideroblastic anemia related to pyridoxine (B6 vitamin) deficiency. Acid folic deficiency was associated. The blood count normalized within one month after vitamin supplementation. CONCLUSION Pyridoxine deficiency must be sought in sideroblastic anemia in patients at risk.

Abstract
Background Little is known about the prevalence of vitamin C deficiency in the population of individuals who are withdrawing from alcohol, and about possible consequences of latent scurvy. The aim of this study was to evaluate the prevalence of vitamin C deficiency in patients who were withdrawing from alcohol, its correlation with latent scurvy (mainly tiredness and weakness) and the change in the latter symptoms at 3 months after oral vitamin C supplementation. Methods A total of 47 patients (33 males, 14 females) who volunteered to undertake alcohol detoxification were included prospectively between January 2014 and November 2016. Determination of vitamin C blood levels was performed, and selected clinical signs of latent scurvy were recorded in a structured questionnaire. The decrease of tiredness after vitamin C supplementation was also studied 3 months after the inclusion of patients who had no other explanation for their weakness. Results About 57.44% of the patients were affected by vitamin C deficiency (< 11.4 mol/L). Less than one-third (29.70%) had a normal plasma vitamin C level. There was a clear correlation between decreased vitamin C levels and the presence of tiredness (P = 0.003) and no correlation between gum inflammation or purpura (P = 0.97 and 0.44 respectively). After 3 months of alcohol withdrawal and vitamin C supplementation, 89% of the patients reported a decrease of tiredness. Conclusions Vitamin C deficiency is prevalent in patients undertaking alcohol detoxification. Patients with this vitamin deficiency status often suffer from tiredness, which may be symptoms of latent scurvy. Even if tiredness is a highly nonspecific symptom, presence of fatigue should draw attention and the vitamin C level should be determined. Our preliminary data suggest that vitamin C supplementation, may decrease fatigue and improve patient’s quality of life. This last evolution needs to be confirmed by a double-blind randomized study.

Abstract
OBJECTIVE: to assess alcohol intake in the bariatric surgery pre and postoperative periods. METHODS: Patients were interviewed atSurgery Clinic of the Hospital das Clínicas da Universidade Federal de Pernambuco - HC/UFPE (Brazil) from July 2011 to March 2012. We analyzed socioeconomic, anthropometric and clinical variables. We used the Alcohol Use Disorders Identification Test (AUDIT C). RESULTS: One hundred nineteen patients were enrolled (mean age: 41.23+11.30 years), with a predominance of the female gender (83.2%), non-Caucasian race (55%), married individuals or in a stable union (65.5%), with a high school education (40.3%)and active in the job market (37%). Weight and body mass index (BMI) were 128.77+25.28Kg and 49.09+9.26Kg/m2,respectively in the preoperative period (class II obesity) and 87.19+19.16Kg and 33.04+6.21Kg/m2, respectively in the postoperative period (class I obesity) (p<0.001). Hypertension was the most frequent disease in the pre (66.6%) and postoperative (36.5%) periods. The prevalence of alcohol use was 26.6% in the preoperative period, of which 2.2% of high risk, and 35.1% in the postoperative period, of which 1.4% of probable dependence; this difference did not achieve statistical significance (p=0.337). CONCLUSION: The prevalence of abusive alcohol intake and/or probable dependence was low in both the pre and postoperative periods, with little evidence of risky consumption among the patients submitted to bariatric surgery.

Abstract
Copper, manganese and selenium are elements involved in protecting the body against oxidative stress. Determining their plasma level may contribute to assessing the health and nutritional status of populations. The aim of this study was to assess factors influencing copper, manganese and selenium plasma levels in an adult Mediterranean population and to identify groups at risk of deficiency. A cross-sectional survey was carried out in Andalusia, a region in southern Spain. Blood samples were obtained in a random subsample of 340 subjects. Food consumption was assessed by 48-h recall. Height, weight, skinfolds, waist and hip circumferences were measured. Copper, manganese and selenium were measured in plasma. Information about physical exercise, educational level, alcohol and smoking habits was obtained with a structured questionnaire. Plasma copper was found to be higher in women than among men. Hypocupraemia was found in 4.4% of the population, while 9.7% presented hypomanganesemia. Moreover, 86.5% presented plasma selenium values below 125microg/L (cutoff for optimal glutathione peroxidase activity). No association was found between plasma elements, anthropometric indices and lifestyle factors; there were tendencies, no more. Copper tended to decrease in obese and increase in sedentary, while selenium tended to decrease among smokers. Plasma Cu was positively correlated with the consumption of monounsaturated and polyunsaturated fats. Plasma Mn was directly correlated with the consumption of dairy products. Levels of Se were positively correlated with age, the consumption of fruit, vegetables, energy obtained from carbohydrates, and the consumption of fibre, and inversely correlated with the consumption of meat and sweets. Our results provide an estimate of the copper, manganese and selenium status in the adult population of southern Spain. The correlations found for Se suggest that there is a tendency for Se levels to be better maintained among the population that shows a stronger preference for the traditional diet.

Abstract
PURPOSE OF REVIEW Preoperative nutritional support in severely malnourished patients decreases complications after major surgery. This review summarizes previous studies on head and neck cancer patients undergoing surgery, and offers recommendations on preoperative nutritional support based on the literature and our experience. RECENT FINDINGS Head and neck cancer has a large impact on the patient's quality of life and a high mortality rate. Aggressive surgical resection followed by soft-tissue and osseous reconstruction is the gold standard of treatment. The incidence of postoperative complications is high at 20-50%. Malnutrition and alcohol withdrawal syndrome are often present, and are considered risk factors for developing wound infection after head and neck cancer surgery. Proactive intervention by preoperative nutritional support may correct nutrient deficiencies, minimize malnutrition-related morbidity and mortality, reduce the length and cost of hospitalization, and may prevent alcohol withdrawal syndrome. Nutritional support given preoperatively for 7-10 days decreases postoperative complications by approximately 10% in malnourished patients with weight loss of 10% or more. Oral liquid supplements and enteral nutrition are useful to support head and neck cancer patients preoperatively. Enteral nutrition is safer, more physiological, less expensive and practicable at home compared with parenteral nutrition, which is not usually indicated in these patients. SUMMARY Enteral nutrition is efficient in preoperative phase to prevent postoperative complications. However evidence is insufficient to conclude that preoperative immune-enhancing enteral feeding provides any supplementary benefit by comparison with a standard diet. Our experience with the preoperative approach in head and neck cancer patients is reported in this paper.
