Background and Aims: The food consumption surveys, conducted for over 30 years by the CREA Research Centre for Food and Nutrition, are the most reliable source of data to evaluate the food consumption intake and dietary patterns of the Italian population. The fourth and most recent survey (IV SCAI 2017-2020), was carried out as part of the pan-European framework 'EU Menu', according to the harmonized methods recommended by European Food Safety Authority (EFSA). The current paper aims to present its main results in terms of food group consumption., Methods and Results: The sample of IV SCAI was stratified by geographical areas and included 1969 individuals aged 3 months to 74 years living in Italy. Dietary assessment was based on food diaries for children, and 24h recalls for adolescents, adults, and elderly, for both techniques on two non-consecutive days. The most consumed food groups were: Milk and Cereals, followed by Fruit, Vegetables, and Meat. At the subgroup level, bread was the most consumed cereal product in terms of quantity (70 g/day), followed by pasta (79 % of consumers; 49 g/day). Only 39 % of individuals had an adequate fruit and vegetable consumption according to the latest World Health Organization (WHO) recommendations, although this percentage increased in adults and the elderly (43 %, and 73 % respectively). Consumption of red and processed meat was also not in line with international recommendations, being slightly higher mainly in adults and adolescents with a mean consumption of 83 g/day and 100 g/day respectively, compared to the WHO recommendation not to exceed 70 g/day., Conclusion: The detailed dietary data collected in IV SCAI are a fundamental evidence platform supporting public health programs, a reliable reference to guide nutritional policies and monitoring diet in the coming years., Competing Interests: Declaration of competing interest The authors have nothing to disclose., (Copyright © 2025 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.

Background and Aim: Cereals' iron content is a major contributor to dietary iron intake in Europe and a potential for biofortification. A simulation of daily iron intake from wheat and rice over the next 20 years will be quantified., Methods: Food items, and energy and iron intake by age classes are estimated using the Italian dietary survey (IV SCAI). Iron intake and adequacy estimation trends were categorized in four scenarios compared to a baseline (basic scenario; only climate change effects): over wheat and rice biofortification effects (scenario 1); over the shift in whole wheat consumption of up to 50% of the total amount of wheat-based foods (scenario 2); over the shift in brown rice consumption up to 100% of the total amount of rice (scenario 3); over the cumulative effects of biofortifications and whole wheat and brown rice consumption (scenario 4)., Results: Increasing the iron intake from wheat and rice biofortification and the shift in whole wheat consumption is similar and sufficient to recover the baseline iron depletion effect due to climate change. The shift in brown rice consumption produces a negligible increment in iron intake. The cumulative effects of the corrective actions considered in the scenarios can significantly reduce the iron intake inadequacy, despite not reaching the recommended levels., Conclusions: Corrective actions including biofortification and whole grain consumption are still far from ensuring the full recovery in children and females of fertile age as at-risk groups of iron deficiency. Further actions are needed considering other biofortified food sources, fortified foods, and/or dietary food diversification.

Background/objectives: The aim of this study was to evaluate the effects of lifelong team handball/football training on regional bone health and body composition in elderly women., Methods: Seventeen elderly women team handball/football players (65.9 ± 5.7 years) and twenty-one untrained age-matched women (controls) (67.7 ± 5.1 years) participated. Whole-body and regional dual-energy X-ray absorptiometry scans of arms, legs, and lower spine (L1-L4) were performed., Results: We observed 8% and 9% higher bone mineral density (BMD) and bone mineral content (BMC), respectively, at the whole-body level and in the legs and 11.5% higher BMC in the legs in team handball/football players compared to untrained age-matched controls ( p < 0.05). Higher total and leg lean body mass ( p < 0.05), along with lower total body fat percentage (p < 0.05) and higher T- and Z-scores, markers of fragility risk fracture (0.294 ± 1.461 vs. -0.538 ± 1.031; 1.447 ± 1.278 vs. 0.724 ± 0.823, respectively), were also found in team handball/football players compared to controls ( p < 0.05). No significant differences in nutritional habits were observed between groups., Conclusions: Our study suggest that the beneficial effects of lifetime handball/football practice on bone preservation in elderly women occur independently from nutritional intake, which emphasize the potential role of team sports in osteoporosis prevention. Future studies should focus on the cofounding factors and causative mechanisms mediated by team sport practice in osteoporosis prevention.

The effects of lifelong football training on bone health, body composition and physiological demands were evaluated. A total of 20 veteran football players (VPG; 73.4 ± 3.7 years) and 18 untrained age-matched men (CG; 75.6 ± 4.2 years) were enrolled. Whole-body and regional dual-energy X-ray absorptiometry scans of arms, legs, proximal femur and lower spine (L1-L4) were recorded in all participants. We observerd higher bone mineral density (BMD) in the whole-body, arms and femoral regions and higher bone mineral content (BMC) in the legs and lower spine compared to the CG ( p < 0.05), also higher total lean body mass ( p < 0.05) and lower total body fat percentage ( p < 0.05), were found. No differences in food habits were evidenced between the VPG and the CG, as evaluated using 3-day food records. Resting heart rate (RHR), blood pressure (BP) and activity profile during a football match were recorded using a global positioning system only in the VPG. The mean heart rate (HR)of theoretical maximal HR (ThHRmax), and peak of ThHRmax were 83.9 ± 8.6% and 98.6 ± 10.2%, respectively; the mean of total distance covered was 3666 ± 721 m, and the means of accelerations and decelerations were 419 ± 61 and 428 ± 65, respectively. Lifelong participation in football training improves regional BMD and BMC in legs, femur and lumbar spine compared to the CG. A high number of intense actions in term of HR and accelerations and decelerations suggests an elevated energy expenditure that in turn correlates to the healthier body composition observed in the VPG compared to the CG.

There are a lot of evidences on the beneficial effects mediated by exercise on the prevention of not communicable diseases (NCDs) including different type of cancer. The production of circulating exerkines transported in exosomes represents a novel pathway activated by exercise. However, the biological mechanisms that could explain the role of exosomes in cancer prevention have been not fully elucidated. The aim of this mini-review is to provide an update on the biological mechanisms bringing the release of muscle-derived exosomes during exercise and cancer prevention., Competing Interests: Authors DV, AA, and PB were employed by CEINGE-Biotecnologie Avanzate Franco Salvatore.

This study aims to assess the carbon footprint associated with vegan, vegetarian, and omnivorous menus for primary school lunches in Italy. For this purpose, healthy and acceptable menus with minimal greenhouse gas emissions have been designed by a binary linear programming model. The results show that the adoption of a specific diet may help in reducing the carbon footprint of menus, but it is the optimal selection of dishes that ultimately makes the difference. Interestingly enough, the optimal choice of dishes and the restriction of meat consumption in omnivorous menus can lead up to a 40% emission reduction compared to the current school lunch menu of the municipality of Rome. Moreover, the optimal choice of dishes in vegan menus provides the menu with the lowest carbon footprint among all kinds of diets., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Benvenuti, De Santis, Ferrari, Martone and Rossi.)

Healthy eating in childhood and adolescence is important for proper growth and development and to establish a healthy foundation for future dietary habits. This paper aims to describe the elaboration of dietary plans for pediatric ages highlighting critical points related to the application of the Italian nutrient recommendations. National databases on food composition data were used to compile the dietary plans. Starting from the definition of serving size for adults, the suggested portion size for pediatric ages was shaped to produce appropriate dietary plans according to the different classes of age. Items from "cereals and derivatives," "milk," "fruit," "vegetables," "olive oil," and "water" groups were included daily. Pizza was included once a week. Sweets and snacks were gradually introduced, once a week in infants and up to five times a week in adolescents. Legumes were provided three times a week, as a source of vegetable and sustainable proteins. The main critical aspect of the dietary plans was related to the monotony, especially for snacks and breakfasts. This work demonstrated the limits of the translation of Italian nutrient recommendations into dietary plans for pediatric age groups. Keeping the protein intake in the recommended range of 8-12% of daily energy resulted in inadequate provision of calcium and iron. Other critical points were the reference values for body weight and physical activity. The proposed dietary plans are adequate with regard to food composition, the intake of energy and several nutrients, and in terms of food selection. However, their implementations require action, information, and advocacy., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Rossi, Martone, Piccinelli, Buonocore, Ghiselli and the Working Group on Pediatric Nutrition of Italian Dietary Guidelines.)

Dietary surveys are conducted to examine the population's dietary patterns that require a complex system of databases, and rules for constructing the data matrix (precision, coding, deriving new variables, e.g., body mass index from individual's height and weight, classes, e.g., age-class, socio-economic status, physical activity, etc.). Management of the data collection requires specialized fieldworkers to allow for the collection of harmonized and standardized data. In this way, only statistical variability is envisaged and any eventual biases are due to probabilistic distribution but data are not affected by inaccuracy. Training the fieldworkers is a crucial part of each dietary survey. The idea to provide constant training throughout the whole survey period, from the preparatory phase to the data collection phase, relies on the necessity to train fieldworkers and monitor the skills acquired during the study, in addition to helping fieldworkers to gain the necessary experience. This study aims to relate the experience in conducting the course path to high specialized interviewers who carried out the cycle devoted to the 10-74 age class of the fourth nationwide food consumption study in Italy (IV SCAI ADULT) according to the European Food Safety Authority (EFSA) guide. A course path was structured in three steps corresponding to the preparation, pilot, and collection phases. The whole path achieved the goal of collecting data related to 12 individuals by each participant, with an overall success rate (successful trainees/total participants) of 16.8% (84 out of an initial 500). The study aimed to provide good quality data in the short term and a highly specialized community in the long term. Surveillance nutritional systems can count on a highly skilled community, so decision-making in public health nutrition and a sustainable and healthy food system can rely on this infrastructure., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Le Donne, Piccinelli, Sette, Martone, Catasta, Censi, Comendador Azcarraga, D’Addezio, Ferrari, Mistura, Pettinelli, Saba, Barbina, Guerrera, Carbone, Mazzaccara and Turrini.)

Background: Physical fitness (PF) levels correlate with health hallmarks at all ages. In this study, w aimed to determine the PF level of schoolchildren from the Campania Region (Italy) through health-related PF (HRPF) components, taking into account body weight and sport practice (SP). Methods: PF level was determined in 565 schoolchildren aged 10−13 (11.7 ± 1.0 yrs; m: 353, f: 212) using some of the Eurofit battery tests. Results: 77% children practiced sport, boys more than girls (86% vs. 63%, respectively; p < 0.05). Boys performed better than girls (p < 0.05) in the Plate Tapping, Standing Broad Jump, Bent-Arm Hang, and 10 × 5 m Shuttle Run tests; girls performed better in the Sit-and-Reach Test (p < 0.05). Conclusion: Overweight/obese status negatively affects the muscular strength of lower limbs, even if it progressively improves during growth. SP was revealed to be a determinant in performance only in some PF tests, likely due to the heterogeneous training level among boys and girls who practice sport.

Background: Childhood obesity is associated with many lifestyle factors. The aim of the present study was to evaluate the relationship between overweight/obesity and abdominal obesity and several lifestyle factors in a sample of Italian adolescents., Methods: A representative cluster sample of 15-16-year-old adolescents in secondary school in the Lazio region (Italy) was recruited. Body weight, height and waist circumference were measured. Ponderal status was assessed by the IOTF and WHO definitions. Waist-to-height ratio (WtHR) cut-off of 0.5 was used to classify subjects with the highest cardiometabolic risk. Selected dietary habits and lifestyle characteristics were assessed by questionnaires., Results: Three hundred sixty-nine adolescents (162 males and 207 females) were studied. Prevalence of overweight/obesity was 23.3%, according to the IOTF criteria with a higher percentage of males than females (30.2% vs. 17.9%; P=0.031), and 26% according to WHO references with significant differences between males and females (respectively, 33.9% vs. 19.8%; P=0.002). The WtHR≥0.5 was observed in 12.7% of the total sample with a higher percentage in males than in females (16% vs. 10.1%). Males reported an increased likelihood of being overweight or obese, as well as of having a WtHR≥0.5 (aOR 2.76 and 2.18, respectively). Adolescents that had breakfast regularly everyday were less likely to be overweight/obese and to have a WtHR≥0.5 (aOR 0.52 and 0.49, respectively)., Conclusions: These results showed a high prevalence of overweight/obesity in the sample, and food habits and lifestyle not in accordance with recommendations, especially regarding breakfast. A Surveillance System of Italian adolescents should also be implemented through anthropometric measurement data to monitor the effectiveness of the policies to counteract obesity.

This study analyses the influence of different area per player (A P ; 75, 98 and 131 m 2 ) on the average metabolic power (MP) and other soccer-related performance variables in relation to the positional roles. We recruited 19 non-professional male soccer players (25.2 ± 6.3 y; 23.7 ± 2.3 kg/m 2 ; 16.4 ± 6.3 y soccer experience) to play three different small-sided games (SSGs): SSG1 (5 vs. 5; 30 × 30 m; 5 min), SSG2 (5 vs. 5; 35 × 45 m; 5 min) and SSG3 (7 vs. 7; 35 × 45 m; 8 min). Specific playing rules were applied. GPS-assessed soccer-related variables were: average MP (AMP), distance covered in 1 min (DIS); % time spent at high speed (v > 16 km/h; % hst) or MP (>20 W/kg; % hmpt); % distance covered at high positive/negative speed (2 < v < 4 m/s 2 , % ACC; -6 < v < -2 m/s 2 , % DEC); and number of actions at high MP (hmpa). All recorded variables differed when each SSG was compared to the others ( p < 0.05), but for hmpa for attackers. Most performance variables were positively associated with increasing A P ( p < 0.05), but for % ACC and % DEC, and differed among positional roles within the same SSG ( p < 0.05). Here the general applicability of SSGs, regardless the physical/technical skills of the group of players, to enhance performance is confirmed; furthermore, quantitative advices on AMP and other performance variables are provided to achieve significant improvements in all soccer players of the team.

National food consumption surveys are crucial for monitoring the nutritional status of individuals, defining nutrition policies, estimating dietary exposure, and assessing the environmental impact of the diet. The methods for conducting them are time and resource-consuming, so they are usually carried out after extended periods of time, which does not allow for timely monitoring of any changes in the population's dietary patterns. This study aims to compare the results of nutrition-related mobile apps that are most popular in Italy, with data obtained with the dietary software Foodsoft 1.0, which was recently used in the Italian national dietary survey IV SCAI. The apps considered in this study were selected according to criteria, such as popularity (downloads > 10,000); Italian language; input characteristics (daily dietary recording ability); output features (calculation of energy and macronutrients associated with consumption), etc. 415 apps in Google Play and 226 in the iTunes Store were examined, then the following five apps were selected: YAZIO, Lifesum, Oreegano, Macro and Fitatu. Twenty 24-hour recalls were extracted from the IV SCAI database and inputted into the apps. Energy and macronutrient intake data were compared with Foodsoft 1.0 output. Good agreement was found between the selected apps and Foodsoft 1.0 (high correlation index), and no significant differences were found in the mean values of energy and macronutrients, except for fat intakes. In conclusion, the selected apps could be a suitable tool for assessing dietary intake.

The stem cell technology and the induced pluripotent stem cells (iPSCs) production represent an excellent alternative tool to study cardiomyopathies, which overcome the limitations associated with primary cardiomyocytes (CMs) access and manipulation. CMs from human iPSCs (hiPSC-CMs) are genetically identical to patient primary cells of origin, with the main electrophysiological and mechanical features of CMs. The key issue to be solved is to achieve a degree of structural and functional maturity typical of adult CMs. In this perspective, we will focus on the main differences between fetal-like hiPSC-CMs and adult CMs. A viewpoint is given on the different approaches used to improve hiPSC-CMs maturity, spanning from long-term culture to complex engineered heart tissue. Further, we outline limitations and future developments needed in cardiomyopathy disease modeling.

Objectives: The benefits of using a fibrin sealant to reinforce the pancreaticojejunal anastomosis are still contentious, a fact that justifies the study of its effects on clinical outcomes and costs of pancreaticoduodenectomy., Methods: Study of 62 consecutive patients submitted to pancreaticoduodenectomy, divided into two groups of 31 patients each: GWS = group with sealant and GWOS = group without sealant that were compared according to demographic, clinical, laboratory aspects, the incidence of postoperative pancreatic fistula (POPF), according to the definition of the International Study Group on Pancreatic Fistula, updated in 2016, and its postoperative complications categorized according to the Clavien classification, as well as hospital costs evaluated by the absorption costing method (with the exception of those related to medications)., Results: The groups were homogeneous and there were no significant differences in the postoperative clinical course or in the indicators of hospital care between them. Hard texture of pancreatic tissue was the only protective factor against the development of POPF (RR = 0.29 (95%CI:0,12-0,68); p = 0.005). Moreover, hospital costs were higher in GWS than in GWOS (p < 0.0001)., Conclusions: The use of fibrin sealant to reinforce pancreaticojejunal anastomosis did not improve the clinical and healthcare outcomes and, in addition, increased hospital costs., Competing Interests: No conflicts of interest., (© 2021 The Authors.)

School is considered a privileged environment for health education and school feeding represents an opportunity for promoting sustainable foods to young generations. The objective of this paper is to demonstrate that is possible to select, from existing school menus, recipes that combine healthy foods with low environmental impact. A national sample of Italian school menus was collected and a total number of 194 recipes were included on a database containing 70 first courses, 83 s courses, 39 side dishes, 1 portion of fruit, and 1 portion of bread. A mathematical model was conceived to combine nutritional adequacy and acceptability criteria while minimizing GHGs emissions. The result is a four-week menu characterized by large vegetable components that were used not only as side dishes but also as ingredients in the first and second courses. Legumes and pasta are often included, and white meat is selected instead of red meat. The findings presented in this paper demonstrated that it is possible to design environmental-friendly meals from existing school menus. The mathematical model developed in this work has the potentiality of being completely scalable, easily updatable, and widely utilizable in different settings either for design or monitoring purposes as well as for research data collection.

The eating patterns in a population can be estimated through dietary surveys in which open-ended assessment methods, such as diaries and interviews, or semi-quantitative food frequency questionnaires are administered. A harmonized dietary survey methodology, together with a standardized operational procedure, in conducting the study is crucial to ensure the comparability of the results and the accuracy of information, thus reducing uncertainty and increasing the reliability of the results. Dietary patterns (i) include several target variables (foods, energy and nutrients, other food components), (ii) require several explanatory variables (age, gender, anthropometric measurements, socio-cultural and economic characteristics, lifestyle, preferences, attitudes, beliefs, organization of food-related activities, etc.), and (iii) have impacts in several domains: imbalance diets; acute and chronic exposures affect health, specifically non-communicable diseases; and then sanitary expenditure. On the other hand, food demand has impacts on the food system: production, distribution, and food services system; food wastes and other wastes generated by food-related activities of the households (e.g., packaging disposal) have consequences on the "health of the planet" which in turn can have effects on human health. Harmonization and standardization of measurement methods and procedures in such a complex context require an ad hoc structured information system made by databases (food nomenclatures, portion sizes, food atlas, recipes) and methodological tools (quantification methods, food coding systems, assessment of nutritional status, data processing to extrapolate what we consider validated dietary data). Establishing a community of professionals specialized in dietary data management could lead to build a surveillance system for monitoring eating habits in the short term, thus reducing costs, and to arrange a training re-training system. Creating and maintaining the dietary data managers community is challenging but possible. In this context, the cooperation between the CREA Research Centre for Food and Nutrition and the Italian National Health Institute (ISS) promoted and supported by the Italian Ministry of Health may represent a model of best practice that can ensure a continuous training for the professional community carrying out a nutritional study., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Turrini, Catasta, Censi, Comendador Azcarraga, D'Addezio, Ferrari, Le Donne, Martone, Mistura, Pettinelli, Piccinelli, Saba, Sette, Barbina, Guerrera, Carbone and Mazzaccara.)

The overweight population is growing in the world, and the search for obesity-associated mechanisms is important for a better understanding of this disease. Few studies with the FTO gene and miRs show how they associate to obesity and how they can impact this disease. The aim of this study was to verify the relationship between the FTO gene and the hsa-miR-150-5p expression with overweight/obesity, lipid profile, and fast blood glucose. Men and women (18 years older or above), with body mass index ≥ 18.5 kg/m2, were enrolled in the present study and the FTO gene and hsa-miR-150-5p expression, biochemical parameters of blood and anthropometric measurements were analyzed. The results highlight that the FTO gene expression is associated to obesity (p 0.029), LDL-C (p 0.02) and fasting blood glucose (p 0.02), but not with triglycerides (p 0.69), total cholesterol (p 0.21), and HDL-C (p 0.24). The hsa-miR-150-5p is not associated to obesity (p 0.84), triglycerides (p 0.57), total cholesterol (p 0.51), HDL-C (p 0.75), LDL-C (p 0.32), and fasting blood glucose (p 0.42). The FTO gene expression is related to obesity, LDL-C and blood fasting glucose, representing a good molecular marker for obesity.

Purpose: The aims of this study were to compare mechanical outputs (i.e. power and impulse), physiological (i.e. heart rate) and perceptual (i.e. effort and fatigue) responses in older men to traditional-set or different cluster-set configuration resistance training protocols., Methods: In a randomized cross-over design, 20 healthy old men (aged 67.2 ± 2.1 years) completed four resistance training sessions using the back squat exercise loaded with optimal power loads. Training configurations were: traditional (TRA), three sets of six repetitions with 120-s rest between each set; Cluster-set 1 (CLU1), 24 single-repetition clusters with 10 s of rest after every cluster; Cluster-set 2 (CLU2), 12 double-repetition clusters with 20-s rest after every cluster; and Cluster-set 4 (CLU4), 6 quadruple-repetition clusters with 40-s rest after every cluster., Results: Cluster-set configurations resulted in greater power outputs compared to traditional-set configuration (range 2.6-9.2%, all p [Formula: see text] 0.07 for main effect and protocol [Formula: see text] set interactions). CLU1 and CLU2 induced higher heart rate (range 7.1-10.5%, all p < 0.001 for main effect and protocol [Formula: see text] set interactions), lower rating of perceived exertion (range - 1.3 to - 3.2 AU, all p [Formula: see text] 0.006 for pairwise comparisons) and lower ratings of fatigue (range - 0.15 to - 4 AU, all p [Formula: see text] 0.012 for pairwise comparisons) compared to TRA and CLU4. Finally, an absolute preference for CLU2 was reported., Conclusions: Findings presented here support the prescription of CLU2 as an optimal resistance training configuration for trained older men using the back squat.

Background: The usefulness of adapted small-sided games (SSGs) in improving cardiac function in subjects with T2DM is still debated. Here we evaluated the effects of 18 weeks indoor muscular activation training (6 weeks; IMA) followed by adapted SSGs football training (12 weeks) on cardiac function, muscular fitness, body composition and adiponectin expression in sedentary T2DM volunteers., Methods: Six T2DM patients underwent IMA protocol of 6 weeks, twice a week followed by 12 weeks SSGs (5-a-side, once a week) training. Glucose, lipid profile and serum homocysteine concentration, body composition (BC), bone mineral density (DEXA), were determined at baseline and after 18 weeks (IMA+SSGs). VO2max and muscular fitness were recorded at baseline and after IMA (6 weeks) and SSGs (12 weeks), respectively., Results: No significant differences were found for VO2max and muscular fitness after 6weeks of IMA. After 18 weeks (6 weeks IMA + 12 weeks SSGs) of training, significant improvements were found in the following parameters: work capacity, VO2peak, Ventilation (VEpeak), breathing reserve consumption and oxygen uptake efficiency slope (P<0.05); leg fitness (P<0.05), BC (P<0.05), vertebral column T-score (P<0.01) and adiponectin (total and high-molecular-weight; P<0.05). Compared to baseline, a reduction in serum homocysteine occurred after 18 weeks of training (P<0.05)., Conclusions: We evidenced that weekly adapted SSGs friendly football matches for 12 weeks improve cardiorespiratory capacity and the expression of independent markers associated with cardiovascular risk in T2DM patients, suggesting an overall reduced CVD-risk in these patients. These preliminary data encourage us to test the efficacy of this type of exercise in a larger population.

Objective: The aim of this study is to define a healthy and sustainable diet model with low GHGE, fulfilling dietary requirements, and considering current Italian food consumption patterns. Design: A duly designed database was developed, linking food nutritional composition and GHGE based on 921 food items consumed in Italy according to the last national food consumption survey (INRAN-SCAI 2005-2006). Linear programming was used to develop new diet plans separately for males and females, aged 18-60 years ( n = 2,098 subjects), in order to minimize GHGE. The program is based on dietary goals and acceptability constraints as well as on 13 nutrient requirement constraints aiming to reach a healthy and acceptable diet for the Italian population. Results: Diet optimization resulted in a nutritionally adequate pattern minimizing GHGE values (4.0 vs. 1.9 kg CO 2 e/day for males and 3.2 vs. 1.6 kg CO 2 e/day for females). In both sexes, the nutrient intake of the optimized diet was at the established lower bound for cholesterol and calcium and at the established upper bound for free sugar and fiber. In males, intake of zinc was at the established lower bound whereas iron was at the established upper bound. Consumption of red meat and fruit and vegetables was at the established lower and upper bound, respectively, in both males and females. Despite the decrease in meat consumption, especially red meat, in the optimized diet with respect to the observed diet, levels of iron intake in females increased by 10% (10.3 vs. 11.3 mg/day) but remained below the adequate intake established in Italian national DRIs. Conclusions: An attainable healthy dietary pattern was developed that would lead to the reduction of GHGE by 48% for males and by 50% for females with respect to current food consumption in the Italian adult population. Health-promoting dietary patterns can substantially contribute to achieve related Sustainable Development Goals., (Copyright © 2020 Ferrari, Benvenuti, Rossi, De Santis, Sette, Martone, Piccinelli, Le Donne, Leclercq and Turrini.)

New competencies may be learned through active experience (experiential learning or learning by doing) or observation of others' experiences (learning by observation). Observing another person performing a complex action facilitates the observer's acquisition of the same action. The present research is aimed at analyzing if the observation of specific explorative strategies adopted in a constrained environment, such as the Radial Arm Maze (RAM), could help young children to explore the maze and to build a cognitive spatial map of the explored environment. To this aim young children were randomly assigned to three groups: children who performed the RAM task following the observation of an actor solving the same maze by putting into action a highly structured exploratory strategy; children who performed the RAM task following the observation of the actor solving the same maze by putting into action a less structured exploratory strategy; children who directly performed the RAM task without any observation. The main result of the present research is that the children who observed the highly structured and correct exploratory strategy spent less time, made fewer errors, exhibited a longer spatial span, and thus they explored the maze more efficiently than the children who directly performed the RAM task without any observation. This finding indicates that when the observed explorative procedure is structured, sequential and repetitive the action understanding and information storage processes are more effective. Importantly, the observation of specific spatial strategies helped the children to build the cognitive spatial map of the explored environment and consequently to acquire/enrich the declarative knowledge of the environment.

Myogenesis is the formation of muscle tissue from muscle precursor cells. Physical exercise induces satellite cell activation in muscle. Currently, C2C12 murine myoblast cells are used to study myogenic differentiation. Herein, we evaluated whether human LHCN-M2 myoblasts can differentiate into mature myotubes and express early (myotube formation, creatine kinase activity and myogenin) and late (MyHC-β) muscle-specific markers when cultured in differentiation medium (DM) for 2, 4 and 7 days. We demonstrate that treatment of LHCN-M2 cells with DM supplemented with 0.5% serum from long-term (3 years) differently exercised subjects for 4 days induced myotube formation and significantly increased the early (creatine kinase activity and myogenin) and late (MyHC-β expression) differentiation markers versus cells treated with serum from untrained subjects. Interestingly, serum from aerobic exercised subjects (swimming) had a greater positive effect on late-differentiation marker (MyHC-β) expression than serum from anaerobic (body building) or from mixed exercised (soccer and volleyball) subjects. Moreover, p62and anti-apoptotic Bcl-2 protein expression was lower in LHCN-M2 cells cultured with human sera from differently exercised subjectst han in cells cultured with DM. In conclusion, LHCN-M2 human myoblasts represent a species-specific system with which to study human myogenic differentiation induced by serum from differently exercised subjects.

This study aimed to investigate the effect of contact (C-SSG) and no-contact (NC-SSG) handball small-sided games (SSGs) on motion patterns and physiological responses of elite handball players. Twelve male handball players performed 10 C-SSG and 10 NC-SSG while being monitored through the heart rate (HR) and rate of perceived exertion (RPE) as physiological responses and time-motion activities profile using video-match analysis. Both game conditions resulted in similar HR responses (P > 0.05), but the NC-SSG led to a higher RPE scores. The time-motion activity analysis featured NC-SSG with a greater amount of walking (855.6 ± 25.1 vs. 690.6 ± 35.2 m) and backward movements (187.5 ± 12.3 vs. 142.5 ± 8.7 m) combined with fast running (232.3 ± 8.5 vs. 159.7 ± 5.7 m) and sprinting (79.5 ± 4.7 vs. 39.7 ± 3.7 m) activities (P < 0.001). Conversely, C-SSG had a higher percentage of jogging and sideway movements associated with greater frequency of jumping (0.87 ± 0.09 vs. 0.31 ± 0.06 nr) and physical contact (1.82 ± 0.55 vs. 0.25 ± 0.03 nr) events (P < 0.001). No between-regimen differences were found for the number of throws (P = 0.745). In addition, the RPE was significantly correlated with fast running relative distances (r = 0.909, P < 0.001) and sprinting relative distances (r = 0.939, P < 0.001). In conclusion, this investigation showed that both C-SSG and NC-SSG in team handball can effectively represent specifically oriented exercises, according to the sport-task and the performance demands.

Dello Iacono, A, Martone, D, Cular, D, Milic, M, and Padulo, J. Game profile-based training in soccer: a new field approach. J Strength Cond Res 31(12): 3333-3342, 2017-The aim of the study was to profile and compare the time-motion, physiological, and neuromuscular responses of both National Youth League (NYL) and UEFA Youth League (UYL) matches with those of an experimental game profile-based training (GPBT) protocol. Time-motion traits and physiological, perceptual, and neuromuscular responses were investigated in 24 male soccer players across 14 matches and 6 GPBT training sessions, for a total of 420 samples. The GPBT had a greater influence on time-motion traits and perceptual responses than the NYL and UYL matches (all p < 0.001). No significant GPBT vs. match differences were found for mean heart rate or blood lactate (F = 1.228, p = 0.304, and F = 0.978, p = 0.385, respectively). Finally, the GPBT protocol led to greater impairment of the neuromuscular explosive performances when compared with those of the postmatch scores (squat jump: F = 19.991, p < 0.001; countermovement jump: F = 61.703, p < 0.001). Results identified the GPBT protocol as characterized by relatively greater high-intensity workloads than official NYL and UYL matches, requiring increased demanding efforts. In light of these outcomes, the GPBT protocol can be considered an advantageous training method for elite soccer players, capable of stimulating the physical effort and physiological capabilities required during a match. This approach is favorable when designing a training intervention according to the principle of sport specificity, as it is based on the specific metabolic demands.

The aim of this study was to evaluate the effects of 6 different areas per player (AP) on exercise intensity (EI) measured during small-sided games (SSGs) and expressed as percentage of maximal heart rate (%MHR) and technical actions (TAs) involvement with the ball, crosses, headers, tackles, shots on goal, dribbling, passing, and target passing-in U-12 and U-14 soccer players during SSGs. Seventeen male U-12 soccer players (age 10.0 ± 0.5 years, body mass 39.3 ± 5.3 kg, and height 143.8 ± 4.6 cm) and 16 male U-14 soccer players (age 13.2 ± 0.3 years, body mass 46.6 ± 11.9 kg, and height 154.8 ± 8.5 cm) performed SSGs with different AP: 40, 50, 66.7, 90, 112.5, and 150 m. Our results indicate that at larger AP, the U-12 group's mean EI values were significantly higher than those at smaller AP (p ≤ 0.05); in addition, intergroup comparison showed that EI was higher in U-12 than that in U-14 players when AP of 112.5 and 150 m were considered (p ≤ 0.05). Technical action analysis evidenced that moving from smaller to larger AP, U-14 players adapted better to AP changes. In conclusion, these results suggest that AP influences differently EI and TAs in U-12 and U-14 players. Our results could be taken into account by conditioning coaches to better tailor the physiological and technical training in young players through the modulation of AP.

Dello Iacono, A, Martone, D, Milic, M, and Padulo, J. Vertical- vs. horizontal-oriented drop jump training: chronic effects on explosive performances of elite handball players. J Strength Cond Res 31(4): 921-931, 2017-This study aimed to assess the chronic effects of vertical drop jump (VDJ)- and horizontal drop jump (HDJ)-based protocols on neuromuscular explosive abilities, such as jumping, sprinting, and changes of direction (COD). Eighteen elite male handball players (age 23.4 ± 4.6 years, height 192.5 ± 3.7 cm, weight 87.8 ± 7.4 kg) were assigned to either VDJ or HDJ group training twice a week for 10 weeks. Participants performed 5-8 sets × 6-10 repetitions of vertical alternate (VDJ) or horizontal alternate (HDJ) 1-leg drop jumps, landing from the top of a platform 25 cm in height. Before and after training, several performance, kinetic, and kinematic variables were assessed. The HDJ led to greater improvement of the sprint time (-8.5% vs. -4%, p ≤ 0.05) and COD performance in comparison with the VDJ (-7.9% vs. -1.1%, p ≤ 0.05), whereas the VDJ caused greater improvement in the vertical jump compared with the HDJ (+8.6% vs. +4.1%, p ≤ 0.05). Moreover, the VDJ regimen compared with the HDJ induced greater changes in the kinetic variables associated with vertical jumping performance, such as peak ground reaction forces (+10.3% vs. +4.3%), relative impulse (+12.4% vs. +5.7%), leg spring stiffness (+17.6% vs. +4.6%), contact time (CT) (-10.1% vs. -1.5%), and reactive strength index (+7.2% vs. +2.1%); all comparisons with p ≤ 0.05. Conversely, the HDJ regimen was able to improve the short-distance and COD performances by increasing the step length (+3.5% vs. +1.5% with p ≤ 0.05) and reducing the CT on COD (-12.1% vs. -2.1% with p ≤ 0.05) more than the VDJ. This investigation showed the crucial role that specific plyometric regimens play in optimizing similar biomechanical featured functional performances, such as jumping, sprinting, and COD.

Aim: This study aimed to evaluate the prevalence of overweight and obesity derived from measured data of weight and height in a cross-sectional sample of adolescents in the Italian region of Lazio and to analyse their association with different socio-demographic factors., Methods: The study was conducted in a representative sample of 15-16-year-old adolescents recruited in secondary schools between December 2011 and May 2012. 369 adolescents were investigated. Body weight, height and waist circumference were measured. The BMI of each subject was calculated, and the prevalence of overweight and obesity was determined by age and sex using the IOTF reference values and WHO growth standards. Waist circumference/height ratio (WC/Ht) was calculated and the subjects were classified using the cut-off of 0.5: WC/Ht≥0.5 and WC/Ht<0.5. Selected socio-demographic characteristics were assessed via questionnaire., Results: The percentages of overweight and obesity were high, 15.4% and 7.9%, respectively, with significant difference between males and females (19.1% vs. 12.6% for overweight and 11.1% vs. 5.3% for obese) using the IOFT reference. The ratio WC/Ht≥0.5 was observed in 12.7% of the sample (all the obese and 29.8% of the overweight subjects). Multiple logistic regression analysis indicated that gender, school municipality, mother's employment status, and family structure had a significant effect on ponderal status (overweight/obesity vs. normal weight)., Conclusion: These findings show a high prevalence of body weight excess associated with socio-demographic factors in the Italian sample investigated, and the need for effective public health interventions to combact obesity with particular attention to disadvantaged adolescents., (Copyright© by the National Institute of Public Health, Prague 2016)

Dello Iacono, A, Martone, D, and Padulo, J. Acute effects of drop-jump protocols on explosive performances of elite handball players. J Strength Cond Res 30(11): 3122-3133, 2016-This study aimed to assess the acute effects of vertical and horizontal drop jump-based postactivation potentiation (PAP) protocols on neuromuscular abilities in tasks such as jumping, sprinting, and change of direction (COD). Eighteen handball players were assessed before and after PAP regimens, consisting of either vertical single-leg drop-jumps (VDJ) or horizontal single-leg drop-jumps (HDJ) single-leg drop-jumps, on countermovement jump (CMJ), linear sprint, shuttle sprint, and agility performance. The HDJ led to greater improvement of the COD performance in comparison with the VDJ (-6.8 vs. -1.3%; p ≤ 0.05), whereas the VDJ caused greater improvement in the CMJ task compared with the HDJs (+6.5 vs. +1%; p ≤ 0.05). Moreover, the VDJ regimens compared with HDJ induced greater changes in most of the kinetic variables associated with vertical jumping performance, such as peak ground reaction forces (+9.6 vs. +1.3%), vertical displacement (-13.4 vs. -5.3%), leg-spring stiffness (+18.6 vs. +3.6%), contact time (-9.2 vs. -1.3%), and reactive strength index (+7.3 vs. +2.4%) (all comparisons with p ≤ 0.05). Conversely, the HDJ regimens were able to improve the COD performance only by reducing the contact time on COD more than the VDJ (-13.3 vs. -2.4% with p ≤ 0.05). The results showed that both PAPs were able to improve the performances that specifically featured similar force-orientation production. This investigation showed the crucial role that different and specific PAP regimens play in optimizing related functional performances. Specifically oriented vertical and horizontal single-leg drop-jump protocols represent viable means for achieving enhanced explosive-based tasks such as jumping and COD.

Vitamin D is thought to regulate skeletal muscle function and boost physical performance. The aim of this study was to assess the relationship between vitamin D and physical performance in physically active children. This cross-sectional study included 125 children who practice football as a leisure activity. Plasma 25-hydroxyvitamin D (25-OHD) was assessed using a chemiluminescence immunoassay method. Vitamin D inadequacy was defined as 25-OHD < 20 ng/mL. Physical performance testing included measurements of muscle strength (maximal isometric contraction), jumping ability (vertical jump, standing broad jump, triple hop test), linear sprint (10 m and 20 m), and agility (9 × 4-m shuttle run). Plasma 25-OHD concentrations were positively correlated with muscle strength (r = 0.539; p < 0.001), vertical jump (r = 0.528; p < 0.001), and standing broad jump (r = 0.492; p < 0.001) but inversely correlated with sprint performance (r = -0.539; p < 0.001). In multivariate analysis models, plasma 25-OHD concentrations were associated with each physical performance parameter independently of age, maturity status, body mass index, fat mass, and protein and calcium intakes. In conclusion, a low plasma 25-OHD level was associated with decreased muscle strength, agility, and jumping and sprinting abilities in physically active children. Vitamin D inadequacy may limit exercise performance. Further research should verify whether correction of vitamin D deficiency enhances physical performance.

Performance-enhancing drugs (PEDs) gained wide popularity not only among sportsmen but also among specific subsets of population, such as adolescents. Apart from their claimed effects on athletic performance, they are very appealing due to the body shaping effect exerted on fat mass and fat-free mass. Besides the "underestimated" massive misuse of PEDs, the short- as well as long-term consequences of such habits remain largely unrecognized. They have been strictly associated with serious adverse effects, but molecular mechanisms are yet to be elucidated. Here, we analyze the current understanding of the molecular effects of supraphysiological doses of doping agents in healthy biological systems, at genomic and proteomic levels, in order to define the molecular sensors of organ/tissue impairment, determined by their misuse. The focus is put on the anabolic androgenic steroids (AASs), specifically testosterone (T) and its most potent derivative dihydrotestosterone (DHT), and on the peptide hormones, specifically the growth hormone (GH) and the insulin-like growth factor-1 (IGF-1). A map of molecular targets is defined and the risk incidence for human health is taken into account.

We investigated whether long-term recreational football training affects the expression of health-related biochemical and molecular markers in healthy untrained subjects. Five untrained healthy men trained for 1 h 2.4 times/week for 12 weeks and 1.3 times/week for another 52 weeks. Blood samples and a muscle biopsy from the vastus lateralis were collected at T0 (pre intervention) and at T1 (post intervention). Gene expression was measured by RTqPCR on RNA extracted from muscle biopsies. The expression levels of the genes principally involved in energy metabolism (PPARγ, adiponectin, AMPKα1/α2, TFAM, NAMPT, PGC1α and SIRT1) were measured at T0 and T1. Up-regulation of PPARγ (p < 0.0005), AMPKα1 (p < 0.01), AMPKα2 (p < 0.0005) and adiponectin was observed at T1 vs T0. Increases were also found in the expression of TFAM (p < 0.001), NAMPT (p < 0.01), PGC1α (p < 0.01) and SIRT1 (p < 0.01), which are directly or indirectly involved in the glucose and lipid oxidative metabolism. Multiple linear regression analysis revealed that fat percentage was independently associated with NAMPT, PPARγ and adiponectin expression. In conclusion, long-term recreational football training could be a useful tool to improve the expression of muscle molecular biomarkers that are correlated to oxidative metabolism in healthy males., (Copyright © 2014 Elsevier Ltd.

The adherence to the Mediterranean diet (MD) of 1740 Italian 8-9-year-olds was evaluated using the KIDMED index and a descriptive analysis of it by socio-demographic and lifestyle factors was performed. Only 5.0% of the children resulted "high" adherers of MD (62.2% "average" and 32.8% "poor"). This scarce adherence was due to a low consumption of fruit, vegetables, legumes, dairy products and a high intake of commercially baked goods for breakfast and sweets. Hindrances to fruit, vegetables and pulses consumption were reported for one-third of the sample. The adherence rates did not differ significantly with BMI and gender. Adherence improved with: having lunch at school; liking lunch at school; breakfast with family; no free access to food; availability of fruit and pulses; liking vegetables; higher maternal education; lower child screen time; population size of place of residence. The results show it is important to improve family food habits and dietary knowledge.

Gene variants in MC4R, SIRT1 and FTO are associated with severe obesity and metabolic impairment in Caucasians. We investigated whether common variants in these genes are associated with metabolic syndrome (MetS) in a large group of morbidly obese young adults from southern Italy. One thousand morbidly obese subjects (62% women, mean body mass index 46.5 kg/m(2), mean age 32.6 years) whose families had lived in southern Italy for at least 2 generations were recruited. Single-nucleotide polymorphisms (SNPs) rs12970134, rs477181, rs502933 (MC4R locus), rs3818292, rs7069102, rs730821, rs2273773, rs12413112 (SIRT1 locus) and rs1421085, rs9939609, 9930506, 1121980 (FTO locus) were genotyped by Taqman assay; blood parameters were assayed by routine methods; the Fat Mass, Fat Free Mass, Respiratory Quotient, Basal Metabolic Rate (BMR) and waist circumference were also determined. Binomial logistic regression showed that the TA heterozygous genotype of SNP rs9939609 in the FTO gene was associated with the presence of MetS in our population [OR (95% CI): 2.53 (1.16-5.55)]. Furthermore, the FTO rs9939609 genotype accounted for 21.3% of the MetS phenotype together with total cholesterol, BMR and age. Our results extend the knowledge on genotype susceptibility for MetS in relation to a specific geographical area of residence., (Copyright © 2014 Elsevier Ltd. All rights reserved.)

The food consumption and food habits of Italian third-class-primary-school children were assessed and their energy and nutrient intakes were compared with requirements. The study involved 1740 subjects (900 males and 840 females) aged 8-9 years, from the north, centre and south of Italy. Body weight and height were measured. Parents filled in a semi-quantitative Food Frequency Questionnaire for their child. The results showed that the diet of Italian children is unbalanced in terms of macronutrients and deficient in fiber. The average daily intakes of fruit (234 g/d), vegetables (134 g/d) and legumes (17 g/d), were lower than the nationally recommended ones. The percentages of energy intake from fats (41%) and from carbohydrates (45%) were higher and lower respectively than recommended. Low intakes of fiber (13.5 g/d) were reported. A national nutrition policy in Italy should focus on nutrition education programs in schools and for parents.

We performed a pilot study using human peripheral blood lymphocytes (PBL) as a novel system to identify new biomarkers of dihydrotestosterone (DHT) and insulin-like growth factor-1 (IGF-1) abuse in sport. First, to obtain a gene signature, we treated cultures of lymphocytes from sedentary males with three doses of 0.237 microg/ml DHT, each of which is 80-fold the physiological concentration in young adult male serum, at days 0, 2 and 4, or with a single dose of 1.25 microg/ml IGF-1, which is 5-fold the physiological concentration in young adult male serum. We then used the Human Genome U133 Plus 2.0 microarray to identify a gene signature related to DHT or IGF-1 administration. Gene expression was evaluated after 7 and 21 days of DHT treatment, and after 24 h, 72 h and 7 days of IGF-1 treatment. Microarray analysis yielded a list of genes whose expression was altered after DHT or IGF-1 treatment. Among these we selected the genes that are most representative of the pathways associated with skeletal and muscular disorders using the IPA bioinformatics tool. We identified six (IDO1, CXCL13, CCL1, GZMB, VDR and IL2RA) and two (FN1 and RAB31) genes that were up-regulated in lymphocytes from sedentary subjects after 7 days of DHT and IGF-1 treatment, respectively. The expression of these genes in lymphocytes from differently trained athletes was either down-regulated or similar to that in lymphocytes from sedentary subjects. This finding suggests that up-regulation was due to the drug and not to physical exercise. In conclusion, we demonstrate that PBL can be useful in anti-doping checks, and we describe new biomarkers of DHT and IGF-1 abuse which can be included in the Athlete's Biological Passport.

Anabolic androgenic steroids, a class of steroid hormones related to testosterone, are natural ligands of androgen receptor (AR), a member of the nuclear receptor superfamily of ligand-activated transcription factors. AR binds specific DNA elements, known as androgen-response elements. Testosterone, the main male sexual hormone, binds AR directly and indirectly, through conversion into dihydrotestosterone (DHT), its more active metabolite. Anabolic androgenic steroids are frequently detected in the urine of doped athletes; their consumption is also growing among sport amateurs and adolescents. The effects of androgens can differ depending on the target cells and/or tissues. To gain insight into transcription activation mechanisms of AR, we investigated AR protein signaling in human peripheral blood lymphocytes treated with supraphysiological doses of DHT. We performed a comparative proteomic analysis and we identified about 30 differentially expressed proteins. At least five species contained a consensus androgen-response elements sequence in the promoter region of related coding genes. The analysis also revealed that high doses of DHT activate the drug detoxification process, could stimulate an increase in cell motility and exert a prosurvival effect rather than an apoptotic one.

The melanocortin-4 receptor (MC4R) is involved in regulating energy homeostasis; mutations in this gene have been associated with 1-5% of early-onset human obesity. The aim of this study was to functionally characterize MC4R mutations identified in morbidly obese subjects living in Southern Italy. We studied their ligand binding, signaling pathway and subcellular localization. As expected, mutants Q43X and S19fsX51, which produce truncated forms of receptor, were devoid of activity. The activity of mutants W174C and A175T were very different even though the mutations are adjacent and are in the same transmembrane helix (TMH). In fact, the production and expression of mutant A175T on the plasma-membrane (PM) was similar to that of the wild-type (wt) receptor and the mutant retained 70% of wt receptor activity; on the contrary, the production of W174C mutant in the cytoplasm was similar to that of the wt receptor and mutant A175T but was only barely detectable on the PM and was devoid of activity. Confocal microscopy showed that W174C remained entrapped in the endoplasmic reticulum (ER) of the cells. Structural analysis showed that substitution of Trp174, located in the middle of TMH4 and 100% conserved in all known MC4Rs, with Cys could impair the relative orientation of TMH2 and TMH4 thereby affecting the overall protein architecture. Furthermore, co-expression studies showed that mutant A175T but not W174C had a dominant negative effect on the wt receptor activity., (Copyright 2010 Elsevier B.V. All rights reserved.)

Aim: The aim of the study was to assess food consumption in a group of Roman adolescents in order to compare the energy and nutrient intakes with requirements., Methods: The authors have carried out a food survey on the whole scholastic population of two schools of Rome from 2003 to 2005. Nutritional status of students was assessed by measuring height, weight according to international indications. Food consumption was assessed by food records., Results: Seventy hundred and seventy three subjects (773) 52% males, with an average age of 12.3 + or - 0.9 years were surveyed. The average daily intakes of fruit (128 g), vegetables (161 g), and legumes (12 g) were lower than recommended. The percentage of energy intake from fat (39%) and that from saturated fats (12%) were high. On the other hand, the percentage of energy intake from carbohydrates was low (46%) even if that from saturated fats (12%) was rather high. The students' diet was characterized by low intakes of fibre (16 g), calcium (815 mg) and iron (12 mg) in both males and females., Conclusion: Results indicate that the diet of these students is unbalanced in terms of macronutrients and deficient for some micro-nutrients, suggesting the need for nutrition education policy.

The present study examined the cardiovascular health effects of 16 weeks of recreational football training in untrained premenopausal women in comparison with continuous running training. Fifty healthy women were matched and randomized to a football (FG, n=25) or a running (RG, n=25) group and compared with a control group with no physical training (CO, n=15). Training was performed for 1 h twice a week. After 16 weeks, systolic and diastolic blood pressure was reduced (P<0.05) in FG (7+/-2 and 4+/-1 mmHg) and systolic blood pressure was lowered (P<0.05) in RG (6+/-2 mmHg). After 16 weeks, resting heart rate was lowered (P<0.05) by 5+/-1 bpm both in FG and RG, and maximal oxygen uptake was elevated (P<0.05) by 15% in FG and by 10% in RG (5.0+/-0.7 and 3.6+/-0.6 mL/min/kg, respectively). Total fat mass decreased (P<0.05) by 1.4+/-0.3 kg in FG and by 1.1+/-0.3 kg in RG. After 16 weeks, pulse pressure wave augmentation index (-0.9+/-2.5 vs 4.2+/-2.4%), skeletal muscle capillarization (2.44+/-0.15 vs 2.07+/-0.05 cap/fib) and low-density lipoprotein/high-density lipoprotein cholesterol ratio were improved (P<0.05) in FG, but not altered in RG. No changes were observed in CO. In conclusion, regular recreational football training has significant favorable effects on the cardiovascular risk profile in untrained premenopausal women and is at the least as efficient as continuous running.

The present study investigated whether football has favorable effects in the treatment of mild-to-moderate arterial hypertension in untrained middle-aged men. Twenty-five untrained males aged 31-54 year with mild-to-moderate hypertension were randomized to a football training group (FTG, two 1-h sessions per week) and a control group receiving physician-guided traditional recommendations on cardiovascular risk factor modification (doctoral advice group, DAG). After 3 months, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were lowered (P<0.05) by 12 +/- 3 and 7 +/- 1 mmHg in FTG, respectively, whereas no significant changes were observed for DAG, with the 3 months values being lower (P<0.05) in FTG than DAG (SBP: 138 +/- 2 vs 148 +/- 2 mmHg; DBP: 84 +/- 2 vs 92 +/- 2 mmHg). The resting heart rate was lowered (P<0.05) by 12 +/- 2 b.p.m. in FTG after 3 months (67 +/- 3 vs 79 +/- 3 b.p.m.), whereas no change was observed for DAG. After 3 months, FTG had higher (P<0.05) VO(2max) (8 +/- 2%; 35.0 +/- 1.6 vs 32.5 +/- 1.3 mL/min/kg) and lower (P<0.05) fat mass (1.7 +/- 0.6 kg), whereas no change was observed for DAG. In conclusion, football training is an attractive non-pharmacological supplement to the treatment of mild-to-moderate arterial hypertension in untrained middle-aged men.

Purpose. To evaluate the relationship between overweight/obesity and dietary/lifestyle factors among Italian adolescents. Methods. On a total of 756 adolescents with mean age 12.4 +/- 0.9, body mass index, food consumption, and time dedicated to after school physical activities and to TV viewing were determined. The data were analysed according to age, nutritional status, and gender. The analysis of variance and multiple logistic regression analysis were performed to investigate the association between dietary/lifestyle factors and overweight/obesity. Results. The percentages of overweight and obesity were, respectively, 28% and 9% among boys, 24% and 7% among girls. The overweight/obesity condition in both genders was associated with parental overweight/obesity (P < .001 for mother), less time devoted to physical activity (P < .001 for boys and P < .02 for girls) and being on a diet (P < .001). Direct associations were also observed between BMI and skipping breakfast and the lower number of meals a day (boys only). Conclusions. This pilot study reveals some important dietary and lifestyle behaviour trends among adolescents that assist with identification of specific preventive health actions.

The purpose of the study was to test a nutrition education intervention to promote a higher consumption of vegetables, pulse and fruit among children. The study involved 274 children of primary school (third and fourth grade). The sample was divided in three groups: A (exposed to intervention without taste education activities), B (exposed to intervention with taste education activities), C (control group not exposed to any intervention). Before starting the intervention on pupils, all teachers were properly trained and parents participated to informative/formative meetings. The teachers were also provided with didactic units to implement on children. The efficacy of intervention was evaluated by measuring food target not eaten at school lunch, before and after the implementation of intervention; it showed less plate waste for vegetables (side dishes) for both groups A and B (53.2% vs 44%) and (23.3% vs 8.1%) respectively, while for fruit only group A reduced to half its reject. The differences were however not significant. No increasing consumption was observed for soups or pasta prepared with vegetables or legumes. According to these preliminary results, we observed for some vegetable food items a better dietary behaviour trend among children of both groups who received the intervention compared with controls.

Objective: To determine the opinion and knowledge of the population of Curitiba about organ donation and transplantation., Methods: The opinion and knowledge about organ donation and transplantation of 1,000 subjects over 18 years of age were determined. The subjects responded to a questionnaire of 20 queries. Respondents had age, gender, social-economic, and education distributions similar to those of the Brazilian population, as defined by the Brazilian Institute of Geography and Statistics (IBGE)., Results: Eighty-seven percent of respondents were in favor of organ donation. There was no difference in the percentage of respondents in favor of donation in relation to gender, marital status, religion, and income. The main reasons in favor of donation were to save life, to help other persons and to donate life. The main reasons against donation were distrust towards medicine or the Brazilian transplantation organization, the existence of organ sale, and fear of body mutilation. Most respondents believed that wealthy people have a better chance to receive an organ than poor people, that sales of organs exists in Brazil, and that misdiagnosis of brain death may occur., Conclusion: Most respondents are in favor of organ donation and have a good knowledge of organ donation and transplantation. The majority distrusts Brazilian organization of organ distribution and brain death diagnosis.

Aim of the study was to detect the prevalence of hypertension among 11-14 years old schoolchildren (n. 487, mean age 12.7 +/- 0.9). The influence on blood pressure (BP) of body mass index (BMI), dietary habits (frequency of breakfast and food items consumption) and life-style was also investigated. Hypertension was defined according to blood pressure tables for children and adolescents of the NIH-Fourth Report (systolic and diastolic BP >95th percentile for age and sex). Overweight and obesity were determined according to the International Obesity Task Force Dietary habits and life-style were investigated by specific questionnaires. The prevalence of overweight and obesity was respectively 31.8% and 10.3% of the subjects studied. Moreover 10.3% of them showed BP values between 90th and 95th percentile and 10.1% was hypertensive. In general the prevalence of overweight (p < 0.05), obesity (p < 0.001) and sedentary activity (p < 0.05) was higher in hypertensive adolescents. The multivariate logistic regression analysis showed a direct association between obesity (OR = 4.35; IC 95% = 2.24-8.44), sedentary life-style (OR = 2.38; IC 95% = 1.17-4.63) and hypertension. Food habits were not associated with BP levels. The results confirmed that an increase of cardiovascular risk in early age was correlated with the increase of the prevalence of obesity and sedentary life-style. Regular measurement of BP together with healthy dietary and life-style indications are recommended to overweight/obese children and adolescents.

Aim: The aim of this study was to investigate the prevalence of overweight/obese and hypertensive roman adolescents belonging to a medium-low social environment. The purpose of this research was also to find out the correlations between high blood pressure and obesity, dietary habits and physical activity., Methods: Nutritional status of 474 subjects (age 12.7+/-0.9 years) of a low-medium social class public school was assessed by measuring height, weight and waist circumference according to international indications. Over-weight and obesity were defined by body mass index (BMI) according to International Obesity Task Force (IOTF). Blood pressure (BP) was measured in duplicate and hypertension was defined by international percentiles. Food habits and lifestyle were investigated by a questionnaire. Multivariate logistic regression was used to relate variables., Results: The prevalence of overweight and obese adolescents was respectively 31.7% and 10.3% with a slight higher presence of males in both cases. The whole sample showed a prevalence of hypertension of 10.1%. Systolic and diastolic BP showed a direct association with BMI and waist circumference (P<0.01). BMI and systolic and diastolic BP were lower in active students (>7 h a week of physical activity). Food habits were not associated with hypertension., Conclusions: The high prevalence of hypertensive adolescents could be explained with the consistent number of overweight/obese subjects, their social medium-low context and their being sedentary. As reported in literature, all these factors may contribute to the ''metabolic syndrome'' aetiology.

Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a multisystemic autosomal recessive disease due to primary thymidine phosphorylase (TP) deficiency. To restore TP activity, we performed reduced intensity allogeneic stem cell transplantations (alloSCTs) in two patients. In the first, alloSCT failed to engraft, but the second achieved mixed donor chimerism, which partially restored buffy coat TP activity and lowered plasma nucleosides. Thus, alloSCT can correct biochemical abnormalities in the blood of patients with MNGIE, but clinical efficacy remains unproven.

Aim: The aim of this research was to evaluate the incidence of hypertension in adolescents by assessing their anthropometric measurements and diet, since recent literature data suggest that 30% of obese adolescents are hypertensive., Methods: The 293 schoolchildren engaged in the study were aged 11-14 years and 54% were male. They attended a Secondary School in Rome with a middle-high class background. Blood pressure, heart rate, weight, height, tricipital and subscapular skinfolds and body mass index (BMI) were measured and dietary patterns assessed through 24-h recall. The findings were then statistically evaluated., Results: The incidence of hypertension was 6.5%, without distinction between sexes. On the basis of the statistical evaluation of the correlations between hypertension and obesity, familial hypertension, weaning with the addition of salt and bottle-feeding from birth, only obesity was found to be statistically significant (p<0.001). Even though the hypertensive adolescents had a high intake of snacks, salt, meat, sausages and cheese in their daily diet, only the excess of proteins was statistically significant (p<0.05). The incidence of obesity (calculated as being 20% over the ideal weight for a given height) was 17.3%. This finding was confirmed by the mean value of the both skinfolds, whereas BMI, for which obesity and overweight were considered together, showed a slight overestimation of this percentage., Conclusion: A high number of hypertensive adolescents was found, about 1/3 of the obese adolescents examined. This confirms the findings of an extensive study previously carried out by the Group of Hypertension of the Italian Society of Pediatrics. From a nutritional point of view, the excessive intake of proteins of the 19 hypertensive adolescents was found to be statistically significant. However, a more extensive study could probably provide further data on other nutrients which, in this case, were not quite statistically significant.

The human small nuclear ribonucleoprotein SNRPB ' /B gene is alternatively spliced to produce the SmB or SmB' spliceosomal core proteins. An ancestral duplication gave rise to the closely related SNRPN paralog whose protein product, SmN, replaces SmB'/B in brain. However, the precise evolutionary and functional relationship between these loci has not been clear. Genomic, cDNA and protein analyses presented here in chicken, two marsupials (South American opossum and tammar wallaby), and hedgehog, suggest that the vertebrate ancestral locus produced the SmB' isoform. Interestingly, three eutherians exhibit radically distinct splice choice expression profiles, producing either exclusively SmB in mouse, both SmB and SmB' in human, or exclusively SmB' in hedgehog. The human SNRPB ' /B locus is biallelically unmethylated, unlike the imprinted SNRPN locus which is unmethyl-ated only on the expressed paternal allele. Western analysis demonstrates that a compensatory feedback loop dramatically upregulates SmB'/B levels in response to the loss of SmN in Prader-Willi syndrome brain tissue, potentially reducing the phenotypic severity of this syndrome. These findings imply that these two genes encoding small nuclear ribonucleoprotein components are subject to dosage compensation. Therefore, a more global regulatory network may govern the maintenance of stoichiometric levels of spliceosomal components and may constrain their evolution.
