The fatty acid composition of serum phospholipids were analyzed in 20 patients with alcoholic liver cirrhosis (11 with malnutrition and 9 with acceptable nutritional status);25 healthy age and sexmatched adults were used as controls. Cirrhotic patients showed higher levels of palmitic acid and total saturated fatty acids than healthy subjects. Total n-6 and n-3 polyunsaturated fatty acids (PUFA), and levels of linoleic, dihomo-gama linolenic, arachidonic, and docosahexaenoic acid were significantly lower (p<0.001) in patients with alcoholic cirrhosis compared to healthy controls. Significant changes were also found between patients stratified according to nutritional status. In particular, the sum of n-3 PUFA was significantly lower (p<0.001) and ratio of n-6/n-3 fatty acids was higher (p<0.01) in malnourished patients when compared to the patients with acceptable nutritional status. Furthermore, important changes in the levels of saturated fatty acids, palmitoleic and oleic acid and long-chain PUFA were found in wellnourished patients with alcoholic cirrhosis as well. Our present data confirmed evidence that malnutrition is one of the factors that led to lower levels of polyunsaturated fatty acids in patients with alcoholic liver cirrhosis. PUFA supplementation in the latter needs further investigation. © 2013 JCBN.

The present study investigated the quantitative effect of dietary fats and ingestion of alcohol on serum and liver lipids, fatty acid bound to phospholipids and their class distribution of male Wistar rats. The rats in C (control) and A (alcohol) groups were fed a standard laboratory diet, HFC (high fat-control) and HFA (high fat-alcohol) groups were fed a high fat diet (standard diet supplemented with 20 g%w/w, sunflower oil: lard mixture 1: 1) for 6 wk. Alcohol-treated rats consumed alcohol at the rate of 9 g/kgbw/d (15-20% energy). Liver phospholipid (PL) content was decreased, and phospholipid/cholesterol liver molar ratio increased in the alcohol treated rats. The proportion of serum sphingophospho-lipid (Sph) was significantly lower and proportion of phosphatidylcholin (PC) significantly higher in serum PL in alcohol-treated rats. Phospholipid class distribution was unaffected by alcohol feeding in liver. Significantly lower levels of 16:1n-7 and higher levels of 20:5n-3 and 22:4n-6 in the serum PL were observed in the alcohol-treated rats, The groups on the HF diet increased levels of 20:4n-6, 22:4n-6 and total n-6, polyunsaturated fatty acid (PUFA)and decreased levels of 18: 1n-9 and total monounsaturated fatty acids (MUFA)in both liver and serum PL, but n-3 fatty acid increased in serum PL and decreased in liver PL compared to groups on the standard diet. Alcohol fat interaction was evident in MUFA and PUFA/SFA in serum PL and n-6, MUFA, PUFA and polyunsaturated/saturated fatty acid ratios (PUFA/SFA) in liver PL. This study showed that the high fat intake in alcohol-treated rats increased levels of 20:4n-6, 22:4n-6 and 20:4/18:2 ratio, and decreased level of 18:1n-9 in liver and serum phospholipids.

Background/Aim. Obesity is the chronic disease and health threatening condition. The number of obese people in the world has taken epidemic conditions. Medical nutritional therapy is the first choice in the treatment of obesity, but it is also accompanied with a great percentage of attrition and a significant weight regain. The aim of our study was to evaluate if psychiatric and specific psychological factors (impulsivity) could be the predictors of successful weight loss. Methods. A study sample consisted of 84 consecutive overweight/obesity women, 20 to 40 years old, who were willing to adhere to the medical nutrition therapy after the initial anthropometric measurements were performed. All participants received a personalized nutritional counseling and a daily diet treatment with 20% caloric restriction from estimated daily energy requirement. At the beginning of the study, the 90-item Symptom Check-list (SCL-90) and the 30-item Barratt Impulsiveness scale (BIS-11) were administrated. At the end of six months of caloric restriction, the conventional diet therapy and control weight measurement, the patients were divided into two groups: the group I – 40 participants (48%) who lost ≥ 10% of their initial body weight (successful group) and the group II – 44 participants (52%) who lost < 10% of their initial weight (unsuccessful). Results. There were no significant differences between groups in the demographic data (age, education level, employment, marital status), baseline anthropometric measurements, and in the general psychopathology total score. Groups I and II were significantly different in the total BIS-11 score (p < 0.001) and in Factor II (motor impulsivity) (p < 0.05). Conclusion. Even though the successful and unsuccessful diet responded participatnts did not differ in the general psychopathology and symptom dimensions, our results pointed out impulsivity as a discriminative factor between them. The total impulsivity and Factor II (motor impulsivity) as an indicator of binge eating were higher in the unsuccessfully responding overweight/obese women on the conventional diet treatment. A focus on impulsivity in a psychotherapeutic work might leed to better outcomes in the medical nutrition therapy. © 2019 Inst. Sci. inf., Univ. Defence in Belgrade. All rights reserved.
