Abstract
Background The study aimed to assess the effectiveness of an educational intervention promoting adherence to healthy diet and physical activity. Study design Before-after interventional study. Methods Participants were healthy volunteers, 18-70 y old, from Bologna. They followed a training course consisting of seven meetings and signed a contract to comply with the promoted habits, verified through questionnaires at the engagement phase (T0), three months later (T1) and one year later (T2). Results One hundred, fifty-three subjects were involved, 75.8% were evaluated at T1 and 41.2% at T2. More than 80% of the subjects involved at T1 achieved an improvement of planned goals. Moreover, 77% of T1 compliants retained healthy eating and physical activity at T2. Conclusions The proposed pathway of empowerment positively affected nutrition and promotion of physical activity at 3 months after the intervention (T1) and were maintained even after a year. The results appear to be promising for primary prevention across the spectrum of a healthy lifestyle educational approach.

Abstract
Abstract
The study aimed to offer a path of empowerment to promote adherence to healthy diets and physical activity for cancer prevention,according to the recommendations of the World Cancer Research Fund (2007): 5 servings per day of fruit / vegetables, protective food (EVO, green tea, cruciferous, turmeric, dried fruit), practicing at least 30 minutes of moderate physical activity.
Participants were volunteers between 18 - 70 years old divided in groups of 25/30 people. They followed a course of 7 theoretical and practical meetings (lifestyles, resilience and cooking workshops) and they signed a contract to comply with the promoted habits, which were verified through questionnaires administered during the engagement phase (T0), three months after the beginning of the course (T1) and one year after (T2).
Six editions (2014-2017) were made for a total of 153 subjects involved (75% women, average age 54 years old). Of these, 116 eligible subjects (76%) were also evaluated at T1 and 63 volunteers (41.7%) at T2. With respect to the dropped out rate, 24% of the subjects left the study prior T1, while 45% of volunteers left it prior T2. The established goal (40% expected target) was accomplished and excided the expectation, since more than 80% of the subjects involved at T1 achieved an improvement in healthy diet (increased consumption of vegetables and fruit, daily consumption of at least one food with antioxidant action) and physical activity (at least 30 minutes a day).
Furthermore the 77% of T1 compliants (50% expected goal) retained healthy eating and healthy motor behaviors even after a year (T2).
The proposed path of empowerment positively affected nutrition and promotion of physical activity at 3 months after the intervention (T1) and were maintained even after a year. The latter result was partly scale down by a high drop out. The path of empowerment, appropriately adapted, can complete the diagnostic therapeutic pathways for breast cancer and colon cancer survivors.
Key messages
People are easier involved in empowerment paths aimed at fighting a single disease, for example cancer, but good results can be achieved simultaneously for all non-communicable diseases. Motivational communication for healthy eating, physical activity and stress prevention must become an integral part of the therapeutic diagnostic pathways of cancers and non-communicable diseases.

Abstract
Specific personality traits, as assessed by the Temperament and Character Inventory (TCI), have been identified in individuals with obesity, but their association with binge and/or night eating has scarcely been reported. Indeed, our systematic search of Medline (1987 to 2013) yielded only five studies on the issue. Taken together, they suggest that personality traits do not have any significant role in determining body mass index, and therefore obesity class. However, obese individuals, in comparison with normal weight individuals, do seem to have a distinctive personality profile, characterized by low self-directedness and cooperativeness, and obese individuals with binge eating show lower self-directedness than those without. Moreover obese individuals with binge eating and/or night eating share a temperament profile characterized by high novelty-seeking and harm-avoidance, two traits also observed in other eating disorder categories and in clinical depression. Future longitudinal studies are needed to investigate the role of personality traits in the onset of binge eating and night eating in obese individuals, and to clarify their influence, if any, on treatment outcomes. Such information will enable us to determine whether the evaluation of personality traits should be included in the comprehensive assessment of obese individuals.

Abstract
Healthy habits in terms of food intake and physical activity are first-line approach to prevention and treatment of nonalcoholic fatty liver disease, but difficulties arise in turning attempts into practice. Independently of the specific role of individual nutrients, not universally proven, overweight, obesity and diabetes are the specific conditions most frequently associated with hepatic fat accumulation. Accordingly, weight loss is mandatory in the majority of patients; this can be achieved by dietary restriction, but is rarely maintained in the long-term. Physical activity programs, both aerobic and resistance exercise may improve cardiorespiratory fitness, reduce the multiple conditions associated with the metabolic syndrome and help weight loss maintenance. However, motivating sedentary individuals to move is difficult and is favored by structured programs carried out along the lines of cognitive-behavior therapy. The role of behavior therapy is now supported by pilot studies, observational studies and finally by a randomized controlled study with histological outcomes. In the future, behavior interventions might be supported by important technological advances, such as smart phone technology and webbased platforms to facilitate interactive engagement amongst patients and with their health care providers. Lifestyle programs must also incorporate methods of overcoming barriers to accessing health service, engaging with workplace health programs and linking with community attempts to improve public health.

Abstract
Metabolic syndrome and its various features (obesity, hypertension, dyslipidemia, diabetes, and nonalcoholic fatty liver disease) are increasing worldwide and constitute a severe risk for the sustainability of the present universal Italian health care system. Lifestyle interventions should be the first therapeutic strategy to prevent/treat metabolic diseases, far before pharmacologic treatment. The role of diet and weight loss has been fully ascertained, whereas the role of physical activity is frequently overlooked both by physicians and by patients. Physical activity has favorable effects on all components of the metabolic syndrome and on the resulting cardiovascular risk, the cornerstone in the development of cardiometabolic diseases. The quantity and the frequency of physical activity necessary to produce beneficial effects has not been defined as yet, but brisk walking is considered particularly appropriate, as it can be practiced by a large number of individuals, without any additional cost, and has a low rate of injury. The effects of exercise and leisure time physical activity extend from prevention to treatment of the various components of the metabolic syndrome, as well as to mood and quality of life. Any effort should be done to favor adherence to protocols of physical activity in the community.

Abstract
It is very unlikely that our obesity-promoting environment will change in the near future. It is therefore mandatory to improve our knowledge of the main factors associated with successful adoption of obesity-reducing behaviors. This may help design more powerful procedures and strategies to facilitate the adoption of healthy lifestyles in a "toxic" environment favoring the development of a positive energy balance. The aim of this review is to describe the main factors associated with successful adoption of obesity-reducing behaviors and to describe the most recent development, limits, and outcomes of lifestyle modification programs. The evidence regarding predictors of weight loss and weight loss maintenance remains largely incomplete. It is necessary to develop strategies matching treatments to patients' needs to improve successful weight loss and its maintenance. How to detect and how to address these needs is a continuous, challenging, research problem.

Abstract
BACKGROUND Overweight and obesity prevention in childhood and adolescence represent a priority for public health; school is a privileged place for health promotion interventions. OBJECTIVES The study aimed to test the effectiveness of a multicomponent 5-month intervention on the habits of primary school children, making the families aware of the importance of healthy choices. METHODS Two hundred nine children attending the fourth class of primary school, divided into interventional (n = 103) and control arm (n = 106) were included in the study. In the intervention group, parents and teachers received more intense lifestyle counseling, associated with weekly motivational telephone calls to families to motivate further their lifestyle changes. Standard deviation score (SDS) body mass index (BMI) was the primary outcome measure; on open-air games and TV watching were secondary outcomes. RESULTS At baseline, no differences were observed between groups. At 8-month follow-up, mean SDS BMI had decreased by 0.06 units in the intervention arm and increased by 0.12 in controls (time × treatment anova, P < 0.002). Outdoor activities increased from 6.23 h week(-1) to 9.93 in the intervention group (P < 0.001), not in controls. This change was associated differences in TV watching from baseline (intervention, -0.96 h week(-1); P = 0.037; controls, +1.33 h week(-1); P = 0.031). CONCLUSION A multicomponent school-based intervention addressing the needs of children, teachers and families produced a significant and favourable short-term effect on overweight/obese schoolchildren.

Abstract
BACKGROUND Suboptimal glycemic control is a common situation in diabetes, regardless of the wide range of drugs available to reach glycemic targets. Basic research in diabetes is endeavoring to identify new actives working as insulin savers, use of which could delay the introduction of injectable insulin or reduce the insulin dose needed. Commonly available as a nutraceutical, berberine is a potential candidate. METHODS AND RESULTS Because its low oral bioavailability can be overcome by P-glycoprotein inhibitors like herbal polyphenols, we have tested the nutraceutical combination of Berberis aristata extract and Silybum marianum extract (Berberol(®)) in type 2 diabetes in terms of its additive effect when combined with a conventional oral regimen for patients with suboptimal glycemic control. After 90 days of treatment, the nutraceutical association had a positive effect on glycemic and lipid parameters, significantly reducing glycosylated hemoglobin, basal insulin, homeostatic model assessment of insulin resistance, total and low-density lipoprotein cholesterol, and triglycerides. A relevant effect was also observed in terms of liver function by measuring aspartate transaminase and alanine transaminase. The product had a good safety profile, with distinctive gastrointestinal side effects likely due to its acarbose-like action. CONCLUSION Although further studies should be carried out to confirm our data, Berberol could be considered a good candidate as an adjunctive treatment option in diabetes, especially in patients with suboptimal glycemic control.

Abstract
Lifestyle modification based on behavior therapy is the most important and effective strategy to manage the metabolic syndrome. Modern lifestyle modification therapy combines specific recommendations on diet and exercise with behavioral and cognitive strategies. The intervention may be delivered face-to-face or in groups, or in groups combined with individual sessions. The main challenge of treatment is helping patients maintain healthy behavior changes in the long term. In the last few years, several strategies have been evaluated to improve the long-term effect of lifestyle modification. Promising results have been achieved by combining lifestyle modification with pharmacotherapy, using meals replacement, setting higher physical activity goals, and long-term care. The key role of cognitive processes in the success/failure of weight loss and maintenance suggests that new cognitive procedures and strategies should be included in the traditional lifestyle modification interventions, in order to help patients build a mind-set favoring long-term lifestyle changes. These new strategies raise optimistic expectations for an effective treatment of metabolic syndrome with lifestyle modifications, provided public health programs to change the environment where patients live support them.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a clinical/biochemical condition associated with the metabolic syndrome. As the disease stems from excess calorie intake and lack of physical activity, the correction of unhealthy lifestyles is the background of any prevention and treatment strategy; drugs should remain a second-line treatment. Several studies have shown that weight loss and physical activity, the cornerstones of a healthy lifestyle, have a specific therapeutic role in NAFLD, preventing disease progression and reducing the burden of disease. Prescriptive diets have a limited long-term efficacy; after a short period, most patients resume their old habits and weight regain is the rule. Physical activity, usually in combination with diet, but also independent of weight loss, improves liver enzymes and reduces liver fat, with uncertain results on hepatic necroinflammation; however, making patients increase their physical activity is very difficult. Only a behavioral approach may give patients the practical instruments to achieve their eating and exercise goals, incorporate them into lifestyle, and maintain the results for a long period, thereby possibly guaranteeing long-term durability of change. Cognitive-behavior treatment should be provided to patients at risk of advanced liver disease, and this action should be coupled with prevention strategies at the population level. Only a synergistic approach and a global societal response might be effective in reducing the burden of advanced liver disease and premature death due to NAFLD/NASH (non-alcoholic steatohepatitis).

Abstract
Large weight losses are rarely achieved through non-surgical procedures, but are also possible without professional help. A massive weight loss may be complicated by the development of an eating disorder psychopathology, followed by weight regain. We report the case of a male patient with super obesity (BMI, 86.2 kg/m(2)), who achieved a massive weight loss (170 kg in 2 years) largely without professional help and without surgery. The final body weight (∼ 100 kg; BMI, 32.6) has now been maintained for nearly 2 years. After weight loss, the patient had massive skin redundancy in several areas including the breasts, arms, abdomen, back, and thighs and a true body weight probably in the normal range. All laboratory tests were normal, with the exception of low free testosterone. Sonographic examination showed gall bladder microlithiasis. No eating disorders and other axis I and axis II psychiatric disorders were present. The case illustrates how much weight loss and weight-loss maintenance can be exceptionally achieved without surgery and without developing an eating disorder of clinical severity or other psychiatric disorders.

Abstract
Excessive weight gain, hypertension, hyperlipidemia, and diabetes are frequently observed in patients having undergone liver transplantation (LTx). These alterations are probably multifactorial in origin, and cluster to generate a metabolic syndrome (MS), increasing the risk of cardiovascular events. We assessed the prevalence of MS (National Cholesterol Education Program-Adult Treatment Panel III criteria) in 296 LTx patients in the course of regular follow-up, at least 6 months after transplantation (median, 38 months). Several pre-LTx and post-LTx data were collected to identify the factors associated with the presence of MS. In a subset of 99 patients, insulin resistance was measured by the homeostasis model assessment. High blood pressure was present in 53% of cases, hyperlipidemia in 51%, high glucose in 37%, and enlarged waist circumference in 32%. Overall, MS (defined as 3 or more of the above features) was present in 44.5% of cases. Insulin resistance (homeostasis model assessment > 2.7) was observed in 41% of cases. Hypertension and hyperlipidemia were more frequent in subjects on cyclosporine than in tacrolimus-treated cases, whereas the type of immunosuppressive drug had no effect on the prevalence of diabetes, enlarged waist, and MS. In a logistic regression analysis, only pre-LTx body mass index (odds ratio, 1.20), body mass index increase (odds ratio, 1.18), and pre-LTx diabetes (odds ratio, 2.36) predicted MS; age, gender, etiology of liver disease, time from LTx, type of immunosuppressive drug, and previous hepatocellular carcinoma were removed from the model. Disorders related to MS are frequent in LTx patients, and are related to both pre-LTx conditions and to weight gain. Weight control is mandatory in LTx patients to prevent risk factors of premature atherosclerosis.

Abstract
The liver plays a central role in the regulation of nutrition by trafficking the metabolism of nutrients, their distribution and appropriate use. Accordingly, protein-energy malnutrition is common in patients with advanced liver disease, and it is a significant prognostic factor, affecting survival, the success of liver transplantation and quality of life. Clinical guidelines for the assessment and treatment of malnutrition have been issued by International societies, suggesting that nutritional therapy should be instituted in all patients where requirements are not adequately met by diet. The supplementation of the diet with amino acids (mainly branched-chain amino acids) and trace elements may improve nutritional status, liver function and hepatic encephalopathy. Nutritional issues should be carefully considered in Liver Units treating patients with advanced cirrhosis, and long-term, carefully controlled studies are needed to better define the type of nutritional support and the amount and timing of administration.

Abstract
BACKGROUND AND AIMS Glargine improves glucose control and reduces the risk of nocturnal hypoglycemia compared with neutral protamine Hagedorn (NPH) insulin. To date, only one study has measured the effects of glargine on health-related quality of life (HRQL); the aim of this study was therefore to confirm the beneficial effects of glargine on disease-specific HRQL in type 1 diabetes. METHODS AND RESULTS Forty-seven patients (mean age, 46 range, 25-74; males, 54%) with diabetes of at least 1-year duration, and with suboptimal glucose control under intensive insulin treatment (IIT), were switched from NPH to glargine. Forty patients maintained on IIT were used as controls. Diabetes-related HRQL was assessed using the Well-being Enquiry for Diabetics (WED), before and after a 6- to 8-month switch to glargine. An 11-item questionnaire based upon diabetes-specific issues was used to assess treatment satisfaction and perceived changes after switching. On glargine, the mean glycosylated hemoglobin decreased by 0.7% (treatment vs. baseline, P<0.0001) and several WED scores improved (discomfort, P=0.020; impact, P=0.0002; total score, P=0.0005). WED changes were associated with a lower perceived risk of hypoglycemia and less problems in daily life on glargine. CONCLUSIONS The results of this study show that the beneficial effect of glargine is not limited to better metabolic control; the burden of type 1 diabetes mellitus on everyday life is also reduced.

Abstract
Clinical and epidemiologic studies have associated non-alcoholic fatty liver with the metabolic syndrome, with insulin resistance as the pivotal pathogenic factor. Obesity, type 2 diabetes mellitus, dyslipidemia, and hypertension contribute to risk for liver disease and to disease progression. The presence of multiple metabolic abnormalities is associated with the severity of liver disease. Patients have a high risk for cardiovascular morbidity and mortality, mediated by early atherosclerosis. This evidence has precise therapeutic implications: only a behavioral approach to lifestyle correction will address all alterations characterizing the metabolic syndrome, including metabolic liver disease.

Abstract
PURPOSE OF REVIEW Clinical, epidemiological and biochemical data strongly support the concept that nonalcoholic fatty liver disease is the hepatic manifestation of the metabolic syndrome. Insulin resistance is the common factor connecting obesity, diabetes, hypertension and dyslipidemia with fatty liver and the progression of hepatic disease to steatohepatitis, fibrosis, cirrhosis and hepatocellular carcinoma. RECENT FINDINGS The association of nonalcoholic fatty liver disease with the features of the metabolic syndrome has been confirmed in several epidemiological studies. The diagnostic and clinical significance of raised liver enzymes has been questioned; advanced hepatic disease may also be present in individuals with ultrasonographically detected steatosis and normal aminotransferase levels. The role of adipokines (leptin, adiponectin) and cytokines (tumor necrosis factor-alpha, interleukin-6, transforming growth factor-beta) in disease progression is probably pivotal, mediated by oxidative stress. The importance of iron accumulation in this process has not been confirmed. Treatments aimed at weight loss remain a primary option; among pharmacological interventions, insulin sensitizers (glitazones and metformin) have confirmed beneficial effects on both biochemical and histological data, but new treatments are on the horizon. SUMMARY Nonalcoholic fatty liver disease prevalence in Western countries is high and there is a trend towards a further increase, with millions of people at risk of advanced liver disease. The epidemiological evidence, the lifestyle origin of the disease and the cost of pharmacotherapy make prevention a primary goal, and will contribute to making behavior therapy the background treatment. We need specific programs and carefully controlled, randomized studies to tackle simultaneously all the components of the metabolic syndrome.

Abstract
Because of their peculiar role in whole-body nitrogen metabolism and the competitive action on amino acid transport across the blood-brain barrier, branched-chain amino acids (BCAAs) have been extensively used in subjects with liver disease to preserve or to restore muscle mass and to improve hepatic encephalopathy. There are no data regarding safe limits of BCAA administration; the results appear to be better when BCAA-enriched formulas or BCAA-supplemented diets are preferred to pure BCAA formulas. Improved nitrogen retention might ameliorate the nutritional status, a prognostic index of long-term survival in cirrhosis and of short-term survival in patients undergoing surgical procedures. The effects on nutrition and ultimately on prognosis of patients with advanced cirrhosis were confirmed in a large multicenter, long-term trial where oral BCAA supplements were compared with equicaloric or equinitrogenous-equicaloric supplements (maltodextrin or lactoalbumin). Similarly, BCAA treatment improved the prognosis of patients with hepatocellular carcinoma, treated by surgical resection or chemoembolization, and of liver transplant patients. The mechanism(s) for the beneficial effects of BCAAs might be mediated by their stimulating activity on hepatocyte growth factor, favoring liver regeneration. The debate regarding the potential effectiveness of BCAAs dates back to the early 1980s. The number of patients who cannot tolerate dietary proteins in amounts sufficient to meet the higher catabolism of advanced liver disease is probably low, but BCAAs remain the sole treatment of proved efficacy in this specific setting.

Abstract
PURPOSE OF REVIEW Branched-chain amino acids (BCAAs) have a peculiar role in whole-body nitrogen metabolism. BCAAs are a substrate for protein synthesis, and have been used to conserve or restore muscle mass in advanced liver disease. In addition, the competitive action of BCAAs on amino acid transport across the blood-brain barrier may improve hepatic encephalopathy. RECENT FINDINGS The effects of branched-chain amino acids on nutrition and ultimately on prognosis of patients with advanced cirrhosis have been confirmed in a large multicenter, long-term trial. Similarly, BCAA treatment improved the prognosis of patients with hepatocellular carcinoma, treated by chemoembolization. The mechanism for the beneficial effects of BCAA is likely to depend on the stimulating activity of BCAA on hepatocyte growth factor, favoring liver regeneration. SUMMARY After an experience of 25 years with branched-chain amino acids, new data supports their beneficial effect in liver diseases. Although the number of patients who cannot tolerate dietary proteins in amounts sufficient to meet their increased catabolism is probably low, in this specific setting BCAAs remain the sole treatment of proved efficacy.

Abstract
PURPOSE OF REVIEW Branched-chain amino acids (BCAAs) have a peculiar role in whole-body nitrogen metabolism. BCAAs are not only a substrate for protein synthesis, but also modulate several components of the synthetic machinery and help to conserve muscle mass; accordingly, several conditions, characterized by protein loss and catabolic status, are likely to benefit from amino acid administration. In addition, the competitive action of BCAAs on amino acid transport across the blood-brain barrier may ultimately alter the synthesis of brain neurotransmitters, involved in neurological diseases. RECENT FINDINGS Both putative actions of BCAAs have been tested in controlled clinical studies in the last few years. The beneficial effects on nutrition were reported to improve muscle performance, reduce protein loss during bed-rest, favor weight loss in obesity, reduce catabolism in trauma patients and improve clinical outcomes in patients with advanced cirrhosis. In this last area, the effects on nutrition might be coupled with the effects on hepatic encephalopathy mediated by improved neurotransmission, successfully tested in mania, tardive dyskinesia and spinocerebellar degeneration. SUMMARY After 30 years of investigation with BCAAs, new studies each year provide further evidence supporting their beneficial effect in a variety of diseases. There is a need for long-term, randomized clinical studies, both in the prevention and in the treatment of various pathological conditions.

Abstract
Non-alcoholic fatty liver disease is now recognized as a cause of potentially progressive liver damage, posing patients at risk of advanced liver failure. Unfortunately, the natural history of disease is only partly known, the disease is slowly progressive and therapeutic outcomes are difficult to define. These factors have limited therapeutic trials to pilot studies, and very few randomized-controlled studies are available. The concept that insulin-resistance, coupled with oxidative stress, may be the underlying mechanism responsible for fat accumulation and disease progression points to insulin-sensitizing agents (metformin, thiazolidinediones) as the most promising drugs. They proved effective in reducing enzyme levels in the short period, but very limited information is available on liver histology, not to say progression to liver cell failure. Large, long-term, placebo-controlled randomized studies are eagerly awaited. Outside controlled studies, nutritional counselling and physical exercise aimed at moderate weight loss remain the basis of any therapeutic intervention.

Abstract
The role of insulin resistance in non-alcoholic fatty liver disease is suggested by laboratory data (hyperinsulinemia and decreased sensitivity to endogenous and exogenous insulin). The clinical association with features of the metabolic syndrome, particularly in the most aggressive stages of the disease, further confirms a causative role. Fat accumulation in the liver may stem either from genetic defects, primarily responsible for insulin resistance, or excessive calorie intake and visceral obesity, and is mediated by adipocytokines (leptin, adiponectin, tumour necrosis factor-alpha). Progression of fatty liver to steatohepatitis may be the result of an imbalance between pro-inflammatory and anti-inflammatory cytokines, triggering the formation of reactive oxygen species and intrahepatic lipid peroxidation. This process may also be promoted or accelerated by pro-oxidant xenobiotics or environmental factors. Insulin resistance provides a target for specific treatment of non-alcoholic fatty liver, and insulin-sensitising agents (metformin or thiazolidinediones) as well as lifestyle changes to reduce visceral adiposity are the most promising therapeutic options. Future trials need to be performed in order to test the long-term effectiveness of these treatments on the basis of clinically relevant histological outcomes.

Abstract
The clinical significance of liver disease is frequently underestimated in patients with metabolic disorders. In patients followed up in a metabolic unit for diabetes, obesity or hyperlipidemia (n=147), we studied the prevalence and the severity of liver disease, and its relationship with the metabolic syndrome (MS). Cases cared for in a liver unit (n=179) were used as controls. Patients in the metabolic series were older and had a higher prevalence of coronary heart disease. Criteria for the metabolic syndrome were fulfilled in 64% and 22% of cases, respectively (P<0.0001). Liver biopsy was obtained in 44 and 66% of cases. Metabolic patients had a more severe steatosis score (P<0.0001), whereas the scores of fibrosis and necroinflammation were less severe (P=0.0059 and 0.0007, respectively). Histological criteria for non-alcoholic steatohepatitis (NASH) were present in 82% of metabolic cases and 68% cases in the liver series (P=0.057). Liver disease in patients routinely cared for in metabolic units is similar to that observed in patients cared for in liver units, and potentially may progress to terminal liver failure. Liver biopsy is recommended for diagnostic and prognostic purposes, as well as for testing treatment effects in controlled trials.
