Abdominal pain is a common symptom associated with irritable bowel syndrome and inflammatory bowel diseases(IBDs), affecting about 20% of the global population(Grundy et al., 2019). Current pain therapies are poorly effective on visceral pain of intestinal origin and present several side effects, hence the need to identify novel molecular and cellular targets for drug development. The pathophysiology of visceral-abdominal pain,

Obesity plays relevant pathophysiological role in the development of health problems, arising as result of complex interaction of genetic, nutritional, and metabolic factors. Due to the role of adipose tissue in lipid and glucose metabolism, and low grade inflammation, it is necessary to classify obesity on the basis of body fat composition and distribution, rather than the simply increase of body weight, and the Body Mass Index. The new term of adiposopathy(‘‘sick fat'') clearly defines the pathogenic role of adipose tissue. Four phenotypes of obese individuals have been described:(1) normal weight obese(NWO);(2) metabolically obese normal weight;(3) metabolically healthy obese; and(4) metabolically unhealthy obese or "at risk" obese. Moreover, sarcopenic obesity has been related to all the phenotypes. The category of normal weight lean, represented by metabolically healthy normal weight has been classified to distinguish from NWO. It is crucial to recommend a bariatric surgery taking into account adiposopathy and sick fat that occurs with the expansion of fat mass, changing the inflammatory and metabolic profile of the patient. Body fat percentage and genetic polymorphism have to be evaluated to personalize the best bariatric surgery intervention.

AIM To determine the clinical effectiveness of nutritional counseling on reduction of non-alcoholic fatty liver disease(NAFLD) severity, weight loss, metabolic and anthropometric indexes and liver enzymes.METHODS Forty-six adults with NAFLD received a 6-mo clinical and a dietary intervention(based on Mediterranean diet) carried out respectively by a gastroenterologist and a nutritionist with counseling license. The counseling process consisted of monthly meeting(about 45 min each). The effect of the treatment was evaluated monitoring liver enzymes, metabolic parameters, cardiovascular risk indexes, NAFLD severity [assessed by ultrasound(US)] and related indexes. All parameters were assessed at baseline. Biochemistry was also assessed at mid-and end-interventions and US was repeated at end-intervention.RESULTS The percentage of patients with steatosis grade equal or higher than 2 was reduced from 93% to 48% and steatosis regressed in 9 patients(20%). At the end of the treatment the end-point concerning the weight(i.e., a 7% weight reduction or achievement/maintenance of normal weight) was accomplished by 25 out of 46 patients(i.e., 54.3%). As far as the liver enzymes is concerned, all three liver enzymes significantly decrease during the treatment the normalization was particularly evident for the ALT enzyme(altered values reduced from 67% down to 11%). Several parameters, i.e., BMI, waist circumference, waist-to-hip ratio, AST, ALT, GGT, HDL, serum glucose, Tot-Chol/HDL, LDL/HDL, TG/HDL, AIP, HOMA, FLI, Kotronen index, VAI, NAFLD liver fat score and LAP, showed a significant improvement(P dered a safe therapeutic approach for reducing risk and severity of NAFLD and related disease states. The proposed approach may be proposed as a valid and recommended approach for improving the clinical profile of NAFLD patients.

Worldwide prevalence of Helicobacter pylori(H.pylori) infection is approximately 50%,with the highest being in developing countries.We compared cure rates and tolerability(SE) of second-line anti-H.pylori levofloxacin/amoxicillin(LA)-based triple regimens vs standard quadruple therapy(QT).An English language literature search was performed up to October 2010.A meta-analysis was performed including randomized clinical trials comparing 7-or 10-d LA with 7-d QT.In total,10 articles and four abstracts were identified.Overall eradication rate in LA was 76.5%(95% CI:64.4%-97.6%).When only 7-d regimens were included,cure rate was 70.6%(95% CI:40.2%-99.1%),whereas for 10-d combinations,cure rate was significantly higher(88.7%;95% CI:56.1%-109.9%;P dence of SE was lower in LA therapy than QT(OR:0.39;95% CI:0.18-0.85;P = 0.02).A higher rate of side effects was reported in Asian patients who received QT.Our findings support the use of 10-d LA as a simple second-line treatment for H.pylori eradication with an excellent eradication rate and tolerability.The optimal second-line alternative scheme might differ among countries depending on quinolone resistance.

Non-alcoholic fatty liver disease(NAFLD)is one of the most common liver diseases and is related to unhealthy lifestyle habits,characterized by a diet rich in sugars and fats leading to excessive calorie intake,and lack of exercise.In recent years,there is a growing incidence of this pathology,raising the attention of hepatologists,endocrinologists,diabetologists,and nutritionists.In this context,the alimentary regimen adopted by patients with NAFLD has become an increasingly scrutinised parameter.Diet is now considered a crucial factor in the treatment of NAFLD since it has been observed that some functional foods play a beneficial role.These include coffeewhose health effects have already been amply demonstrated.Here we describe the beneficial effects of coffee consumption reported in the NAFLD literature.

Non-alcoholic fatty liver disease(NAFLD)is the most common liver disease worldwide.The mechanisms of the underlying disease development and progression are awaiting clarification.Insulin resistance and obesity-related inflammation status,among other possible genetic,dietary,and lifestyle factors,are thought to play the key role.There is no consensus concerning the pharmacological treatment.However,the dietary nutritional management to achieve weight loss is an essential component of any treatment strategy.On the basis of its components,the literature reports on the effectiveness of the Mediterranean diet in reducing cardiovascular risk and in preventing major chronic diseases,including obesity and diabetes.New evidence supports the idea that the Mediterranean diet,associated with physical activity and cognitive behaviour therapy,may have an important role in the prevention and the treatment of NAFLD.

Nonalcoholic fatty liver disease(NAFLD) is a major cause of chronic liver disease and it encompasses a spectrum from simple steatosis to steatohepatitis, fibrosis, or cirrhosis. The mechanisms involved in the occurrence of NAFLD and its progression are probably due to a metabolic profile expressed within the context of a genetic predisposition and is associated with a higher energy intake. The metabolic syndrome(MS) is a cluster of metabolic alterations associated with an increased risk for the development of cardiovascular diseases and diabetes. NAFLD patients have more than one feature of the MS, and now they are considered the hepatic components of the MS. Several scientific advances in understanding the association between NAFLD and MS have identified insulin resistance(IR) as the key aspect in the pathophysiology of both diseases. In the multi parallel hits theory of NAFLD pathogenesis, IR was described to be central in the predisposition of hepatocytes to be susceptible to other multiple pathogenetic factors. The recent knowledge gained from these advances can be applied clinically in the prevention and management of NAFLD and its associated metabolic changes. The present review analyses the current literature and highlights the new evidence on the metabolic aspects in the adult patients with NAFLD.

The aim of this study is to apply the Nutrient Analysis Critical Control Point (NACCP) process to ensure that the highest nutrient levels in food can determine a beneficial effect on the health of the consumer. The NACCP process involves a sequence of analysis and controls that depart from raw material production to the evaluation of the effect of nutrition on health. It is articulated through the following points: 1) identification of nutrient level in the food;2) identification of critical control points (environmental, genetic data, chemical and physical data, production technology, distribution and administration);3) establishing critical limits that can impoverish and damage the nutrient;4) establishing measures to monitor;5) establishing corrective actions. We selected as biomarkers the total phenolic content (TPC) and total antioxidant capacity (TAC) of a genotyped Italian hazelnut cultivars (Corylus e avellana L.). We performed a clinical study evaluating: a) nutritional status;b) clinical-biochemical parameters;c) low density lipoprotein oxidation (LDL-ox);d) the expression level changes of oxidative stress pathway genes in the blood cell at baseline and after 40 g/die of hazelnut consumption. In this study, we found a significant lowering (p ≤ 0.005) of LDL oxidized proteins, in association with the consumption of 40 g/d of hazelnuts. Also, we found a significant variation (p ≤ 0.005) of gene expression of antioxidant and pro-oxidant genes, between the intake of dietary with and without hazelnuts. This results support the hypothesis that the NACCP process could be applied to obtain significant benefits in terms of primary prevention and for contributing to the amelioration of food management at the consumer level.

In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.
