Aggressiveness, anger and eating disorders: a review

Anger and aggressive behaviours, especially those self-directed, are frequent in subjects suffering from anorexia nervosa and bulimia nervosa. They increase the complexity of the clinical features, change the prognosis and cause a more difficult management of these disorders. In order to elucidate the complex relationships between eating disorders, anger and aggressiveness, the history of traumatic experiences, the prevalence of dissociative, obsessive, impulsive and compulsive symptoms, as well as the role of severe personality disorders in subjects suffering from anorexia nervosa, bulimia nervosa and self-injurious behaviours are considered. In the final section of this paper, a model exploring such a relationship in the light of the undefined sense of self is described.     

Oxaliplatin, 5-fluorouracil/leucovorin and epirubicin as first-line treatment in advanced gastric carcinoma: a phase II study

The association between oxaliplatin and 5-fluorouracil (5-FU) has been extensively reported to improve prognosis of gastric cancer patients. The present study is aimed at evaluating response rate and the toxicity profile of the association with oxaliplatin, 5-FU/lecovorin and epirubicin in gastric cancer patients with locally advanced or metastatic disease. Thirty-six patients have been enrolled and 35 evaluated. The treatment schedule was oxaliplatin (100 mg m(-2)), 5-FU (400 mg m(-2)), leucovorin (40 mg m(-2)) and epirubicin (60 mg m(-2)) intravenously. administered every 3 weeks for 6 months, for a total of 185 therapy cycles . Response rate and toxicity were assessed according to the international WHO criteria. Every patient received a mean of 5.3 therapy cycles in a day-hospital setting. Sixteen of 35 patients (46%) showed an objective response, two complete response and 14 partial response. Median time to progression was 33 weeks with an overall median survival of 49 weeks. During the study, anaemia grade 3 and neutropenia grade 3 were observed in 9 and 11% of patients respectively. A grade 3 periferic sensorial neuropathy was observed in 6% of patients. No life threatening or cardiac toxicity was recorded. The regimen used showed anticancer activity against gastric carcinoma, a tolerable toxicity profile and excellent patient compliance.     

Low adherence of a clinically healthy Italian population to nutritional recommendations for primary prevention of chronic diseases

Background and aimSeveral data demonstrated that dietary habits significantly affect the health state of the population. During recent years all the major scientific associations have provided nutritional recommendations for primary prevention of chronic diseases but few data are available about prevalence of adherence to these recommendations in an otherwise healthy population. The aims of this study were to evaluate dietary habits, and to assess the adherence of the general population to the recommendations for correct nutritional behaviour.Methods and resultsDietary habits, anthropometric and biochemical parameters were evaluated in a population of 932 (367 M; 565 F) clinically healthy subjects living in Florence, enrolled in an epidemiologic study conducted between 2002 and 2004. By comparing the dietary pattern with the nutritional guidelines, the study population reported a hyperproteic and hyperlipidic nutritional pattern, with a considerably low contribution from polyunsaturated fats (PUFA). A low fibre intake is shown in both genders. In addition, food consumption pattern showed an increased consumption of some foods such as meat, both fresh and processed, and a low intake of some “healthy” foods like fruit and vegetables.ConclusionsWe found several nutritional flaws in the dietary habits of a clinically healthy Italian population. In particular, we reported a high intake of animal protein and total fats with a very low contribution from PUFA.     

Glucagon-like peptide (GLP)-1 and leptin concentrations in obese patients with Type 2 diabetes mellitus.

AIMS: To assess differences in circulating leptin and glucagon-like peptide (GLP)-1 concentrations before and after an oral glucose load, in euglycaemic and isoinsulinaemic conditions, between obese patients with and without Type 2 diabetes mellitus. METHODS: Ten male obese (body mass index (BMI) > 30 kg/m2) patients with Type 2 diabetes and 20 matched non-diabetic subjects were studied. Leptin, GLP-1(7-36)amide and GLP-1(7-37) concentrations were measured 0, 30, 60, and 90 min after a 50-g oral glucose load administered 90 min after the beginning of a euglycaemic hyperinsulinaemic clamp. RESULTS: GLP-1(7-36)amide concentrations before the glucose load were significantly lower in diabetic patients than in controls (median (quartiles): 50.5 (44.7-53.2) vs. 128.7(100-172.5) pg/ml; P < 0.01), while no difference was observed in baseline GLP-1(7-37). In non-diabetic subjects, GLP-1(7-36)amide and GLP-1(7-37) concentrations increased significantly after the oral glucose load, while no glucose-induced increase in GLP-1 concentration was observed in diabetic patients. GLP-1(7-36)amide at 30, 60, and 90 min, and GLP-1(7-37) at 30 min, of the glucose challenge, were significantly lower in diabetic patients. Leptin concentrations were not significantly different in diabetic patients when compared to non-diabetic subjects, and they did not change after the oral glucose load. DISCUSSION: Leptin concentrations are not significantly modified in obese Type 2 diabetic patients. GLP-1(7-36)amide baseline concentrations are reduced in Type 2 diabetes; moreover, diabetic subjects show an impaired response of GLP-1 to oral glucose in euglycaemic, isoinsulinaemic conditions. This impairment, which is not the result of differences in glycaemia or insulinaemia during assessment, could contribute to the pathogenesis of hyperglycaemia in Type 2 diabetes mellitus.     

Anorexia nervosa and celiac disease: two case reports

OBJECTIVE: Anorexia nervosa (AN) has been reported to be associated with several chronic medical illnesses. In this study, we report two cases of women suffering from AN and celiac disease. The former received the diagnosis of celiac disease before the onset of the eating disorder. For the latter, the diagnosis of celiac disease followed that of AN. Authors discuss the complex relationships between celiac disease and AN. They suggest that in the first case the dietary restriction could act as a trigger for the eating disorder, whereas in the second case, the onset of celiac disease could have exacerbated the clinical symptoms of AN.
