Background Physical and psychological factors, like wrong attitudes and behaviours, can negatively influence health outcomes of the patients receiving allogeneic hematopoietic stem cell transplantation (AHSCT). Educational interventions aiming to improve knowledge on side effects, risks, complications and preventive behaviour can reduce psychological distress, and improve quality of life (QoL). We aimed to compare a standard approach with therapeutic patient education (TPE) to analyse the impact on AHSCT patients’ QoL, psychological distress and knowledge of AHSCT side effects, risks complications and preventive behaviour. Material and methods A prospective interventional study was conducted analysing data of 36 patients who received one of two different educational approaches, which were a standard approach (not-exposed) or TPE (exposed). Results In the exposed group QoL improved 14 days after transplantation (42.2 vs 25.6; p

Summary Background & aims Oxidative stress (OS) could play a role in metabolic syndrome-related manifestations contributing to insulin resistance (IR). The aim of the present study was to gain insight the relationships between OS, IR and other hormones involved in caloric balance, explaining the effects of a natural antioxidant-enriched diet in patients affected by metabolic syndrome. Methods We investigated the effects of dietary antioxidants on IR, studying 53 obese (20 males and 33 females, 18–66 years old, BMI 36.3 ± 5.5 kg/m2), with IR evaluated by Homeostasis Model Assessment (HOMA)-index, comparing 4 treatments: hypocaloric diet alone (group A) or plus metformin 1000 mg/daily (group B), natural antioxidants-enriched hypocaloric diet alone (group C) or plus metformin (group D). A personalized program, with calculated antioxidant intake of 800–1000 mg/daily, from fruit and vegetables, was administered to group C and D. The glycemic and insulinemic response to oral glucose load, and concentrations of total-, LDL- and HDL-cholesterol, triglycerides, uric acid, C reactive protein, fT3, fT4, TSH, insulin-like growth factor 1 were evaluated before and after 3-months. Plasma Total antioxidant capacity was determined by H2O2-metmyoglobin system, which interacting with the chromogen ABTS generates a radical with latency time (LAG) proportional to antioxidant content. Results Despite a similar BMI decrease, we found a significant decrease of HOMA and insulin peak only in group B and D. Insulin response (AUC) showed the greatest decrease in group D (25.60 ± 8.96%) and was significantly lower in group D vs B. No differences were observed in glucose response, lipid metabolism and TAC (expressed as LAG values). TSH values were significantly suppressed in group D vs B. Conclusions These data suggest that dietary antioxidants ameliorate insulin-sensitivity in obese subjects with IR by enhancing the effect of insulin-sensitizing drugs albeit with molecular mechanisms which remain yet to be elucidated.
