The aim of this mini-review is to present the current knowledge on iodine requirements in developmental age, from conception to adolescence. It is based on the analysis of updated national and international guidelines on iodine intake and the prevention of iodine deficiency. Health policy initiatives carried out in industrialized countries in previous decades have led to a dramatic improvement in nutritional iodine status in the general population. However, the prevention of iodine deficit continues to be a concern, especially for vulnerable categories, like adolescents and pregnant women.

Multisystem inflammatory syndrome in children (MIS-C) is a pediatric hyperinflammatory syndrome related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection whose epidemiology is not very well known at present. The objective of the study was to better understand the incidence of MIS-C in the Apulia region in southern Italy. Our primary goal was to estimate the incidence of newly identified cases of MIS-C in children aged 0–18 years, during a period of six months, encompassing the second pandemic wave. We also analyzed the characteristics of our cohort in terms of clinical features, treatment, and outcomes. The cumulative incidence of MIS-C was 3.27 per 100,000 residents between 0 and 18 years of age. In our cohort, gastrointestinal, mucocutaneous, and cardiac involvement were the most common clinical features. With our step-up approach to therapy, no patients required intensive care unit (ICU) admission and no cardiac sequelae after 6 months of onset were found in echocardiograms. Conclusion: Our epidemiological study of MIS-C in southern Italy showed unexpectedly overlapping figures with other US studies.

Posterior reversible encephalopathy syndrome (PRES) is a variable etiology clinical syndrome with similar neuroimaging results and clinical symptoms. PRES can develop in both adults and children and is characterized by headaches, disorders of consciousness, seizures and especially focal visual disturbances, often associated with hypertensive state. In most cases, symptoms resolve without neurological consequences. The treatment strategy concerns early diagnosis and general measures to correct the underlying cause of PRES. Here, we report a case of PRES that occurs in a 6-year-old child with nephrotic syndrome.

Numerous studies in recent decades have shown that Mediterranean diet (MD) can reduce the risk of developing obesity in pediatric patients. The current narrative review summarizes recent evidence regarding the impact of MD across the different stages of child development, starting from fetal development, analyzing breastfeeding and weaning, through childhood up to adolescence, highlighting the gaps in knowledge for each age group. A literature search covering evidence published between 1 January 2000 and 1 March 2022 and concerning children only was conducted using multiple keywords and standardized terminology in PubMed database. A lack of scientific evidence about MD adherence concerns the age group undergoing weaning, thus between 6 months and one year of life. In the other age groups, adherence to MD and its beneficial effects in terms of obesity prevention has been extensively investigated, however, there are still few studies that correlate this dietary style with the incidence of non-communicable diseases. Furthermore, research on multi-intervention strategy should be implemented, especially regarding the role of education of children and families in taking up this healthy dietary style.

Infantile acute upper gastrointestinal bleeding involves a decision for therapeutic intervention that most pediatricians first coming into contact with the patient are, not unreasonably, unable to objectively provide. Therefore, some objective tools of individual risk assessment would seem to be crucial. The principal aim of the present study was to investigate the anamnestic and clinical parameters of infants with hematemesis, together with laboratory and instrumental findings, to create a scoring system that may help identify those infants requiring an appropriate and timely application of upper gastrointestinal (GI) endoscopy.Clinical data of infants admitted for hematemesis to the participating centers over the study period were systematically collected. According to the outcome dealing with rebleeding, need for blood transfusion, mortality, finding of GI bleeding lesions, or need for surgical intervention, patients were blindly divided into a group with major clinical severity and a group with minor clinical severity. Univariate and multivariate logistic regressions were conducted to investigate significant prognostic factors for clinical severity.According to our findings, we drafted a practical diagnostic algorithm and a clinical score able to predict the need for timely upper GI endoscopy (BLOVO infant score). Our clinical scoring system was created by incorporating anamnestic factors, clinical parameters, and laboratory findings that emerged as predictors of a worst outcome.We provided the first objective tool of individual risk assessment for infants with hematemesis, which could be very useful for pediatricians first coming into contact with the patient in the emergency department.

Lung cancer is the most lethal cancer: it has a significant incidence and low survival rates. Lifestyle has an important influence on cancer onset and its progression, indeed environmental factors and smoke are involved in cancer establishment, and in lung cancer. Physical activity is a determinant in inhibiting or slowing lung cancer. Certainly, the inflammation is a major factor responsible for lung cancer establishment. In this scenario, regular physical activity can induce anti-inflammatory effects, reducing ROS production and stimulating immune cell system activity. On lung function, physical activity improves lung muscle strength, FEV1 and forced vital capacity. In lung cancer patients, it reduces dyspnea, fatigue and pain. Data in the literature has shown the effects of physical activity both in in vivo and in vitro studies, reporting that its anti-inflammatory action is determinant in the onset of human diseases such as lung cancer. It has a beneficial effect not only in the prevention of lung cancer, but also on treatment and prognosis. For these reasons, it is retained as an adjuvant in lung cancer treatment both for the administration and prognosis of this type of cancer. The purpose of this review is to analyze the role of physical activity in lung cancer and to recommend regular physical activity and lifestyle changes to prevent or treat this pathology.

Objectives: In this commentary we emphasize the importance of breakfast for children, both from the point of view of proper nutritional education and as a strategy for the prevention of obesity. Methods: We reviewed the international literature, drawing particularly on information regarding the possible negative effects of skipping breakfast. Results: Obese children often do not eat breakfast and may face metabolic problems such as insulin resistance and hypercholesterolemia. The child who does not eat breakfast often becomes an adult who does not eat breakfast. The role of parents is fundamental in the acquisition of correct eating habits. Conclusions: The awareness that habits during childhood become elements of everyday life in adulthood, makes us understand the importance of the long-term consequences of skipping breakfast during childhood and adolescence.

Background Exclusive enteral nutrition (EEN) is the first choice to induce remission and promote mucosal healing in pediatric Crohn’s disease (CD). However, full adherence to EEN treatment may be problematic for children with CD. Methods The goal of the current multicenter retrospective study was to define predictive factors of nonadherence to treatment and nonremission at the end of induction treatment. Those data together were analyzed with the ultimate goal of trying to define an individualized induction treatment for children with CD. Results Three hundred seventy-six children with CD from 14 IBD pediatric referral centers were enrolled in the study. The rate of EEN adherence was 89%. Colonic involvement and fecal calprotectin >600 μg/g at diagnosis were found to be associated with a reduced EEN adherence. Exclusive enteral nutrition administered for 8 weeks was effective for inducing clinical remission in 67% of the total cohort. Factors determining lower remission rates were age >15 years and Pediatric Crohn’s Disease Activity Index >50. Conclusion Although EEN is extremely effective in promoting disease remission, several patients’ related factors may adversely impact EEN adherence and response. Personalized treatments should be proposed that weigh benefits and risks based on the patient’s disease location, phenotype, and disease activity and aim to promote a rapid control of inflammation to reduce long-term bowel damage.

Introduction: The present study aimed at evaluating Italian epidemiological trends of pediatric inflammatory bowel diseases (IBD) over the period 2009–2018. Materials and methods: Data from 1969 patients enrolled in the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition Registry, by 49 pediatric IBD centers throughout the country, were analyzed, comparing three different time intervals (2009–2012, 2013–2015, 2016–2018). Results: The number of new IBD diagnoses ranged from 175 to 219 per year, evenly distributed over the examined period of time. From 2009 to 2018, the minimal incidence ranged from 1.59 to 2.04 /105 inhabitants aged < 18 years, with an overall slight predominance of ulcerative colitis (UC) over Crohn's disease (CD) (ratio: 1.1). Mean diagnostic delay was 6.8 months for CD and 4.1 months for UC, with a significant reduction for CD when comparing the three-time intervals (p =0.008). The most frequent disease locations according to the Paris classification were ileocolonic for CD (41.3%) and pancolitis for UC (54.6%). Conclusions: The minimal incidence rate in Italy seems to have stabilized over the last two decades, even if it has increased when compared to previous reports. UC is still slightly more prevalent than CD in our country. Diagnostic delay significantly decreased for CD, reflecting an improved diagnostic capacity.

Urinary tract infections (UTIs) are among the most frequent bacterial diseases in infants and children. Physician adherence to recommendations is notoriously often poor, but no data are available on UTIs management in the emergency setting. In this multicenter national study, we investigated the policies regarding UTIs management in children aged 2 months to 3 years in Italian emergency units. Between April and June 2021, directors of the emergency units were invited to answer an online survey on the following items: diagnostic approach to children with fever without an apparent source, therapeutic approach to UTIs, the use of kidney and urinary tract ultrasound, and the criteria for hospitalization. A total of 121 (89%) out of 139 of invited units participated in the study. Overall, units manage children with a suspected or confirmed UTI according to available recommendations for most of the items. However, in almost 80% (n = 94) of units, a sterile perineal bag is used to collect urine for culture. When urine is collected by cathether, heterogeneity exists on the threshold of bacterial load considered for UTI diagnosis. Conclusions: Available recommendations on UTIs in children are followed by Italian emergency units for most of the items. However, the methods to collect urine specimens for culture, one of the crucial steps of the diagnostic work-up, often do not align with current recommendations and CFU thresholds considered for diagnosis largely vary among centers. Efforts should be addressed to validate and implement new child and family friendly urine collection techniques. What is Known:• Several guidelines are published on the management of children with suspected or confirmed urinary tract infection.• No data are available on the management of pediatric urinary tract infections in the emergency setting. What is New:• Almost 80% of the Italian emergency units employ a sterile perineal bag to collect urine for culture.• Diagnostic CFU thresholds largely vary among centers.

Background Cyclic Vomiting Syndrome (CVS) is a rare functional gastrointestinal disorder, which has a considerable burden on quality of life of both children and their family. Aim of the study was to evaluate the diagnostic modalities and therapeutic approach to CVS among Italian tertiary care centers and the differences according to subspecialties, as well as to explore whether potential predictive factors associated with either a poor outcome or a response to a specific treatment. Methods Cross-sectional multicenter web-based survey involving members of the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP) and Italian Society of Pediatric Neurology (SINP). Results A total of 67 responses were received and analyzed. Most of the respondent units cared for less than 20 patients. More than half of the patients were referred after 3 to 5 episodes, and a quarter after 5 attacks. We report different diagnostic approaches among Italian clinicians, which was particularly evident when comparing gastroenterologists and neurologists. Moreover, our survey demonstrated a predilection of certain drugs during emetic phase according to specific clinic, which reflects the cultural background of physicians. Conclusion In conclusion, our survey highlights poor consensus amongst clinicians in our country in the diagnosis and the management of children with CVS, raising the need for a national consensus guideline in order to standardize the practice.

The prevalence of primary hypertension in pediatric patients is increasing, especially as a result of the increased prevalence of obesity in children. New diagnostic guidelines for blood pressure were published by the American Academy of Pediatrics (AAP) in 2017 to better define classes of hypertension in children. The aim of our study is to evaluate the impact of new guidelines on diagnosis of hypertension in pediatrics and their capacity to identify the presence of cardiovascular and metabolic risk. Methods: Retrospective clinical and laboratory data from 489 overweight and obese children and adolescents were reviewed. Children were classified according to the 2004 and 2017 AAP guidelines for systolic and diastolic blood pressure. Lipid profile and glucose metabolism data were recorded, triglyceride/HDL ratio (TG/HDL) was calculated as an index of endothelial dysfunction. Hepatic steatosis was detected using the ultrasonographic steatosis score. Results: Children with elevated blood pressure increased from 12.5% with the 2004 AAP to 23.1% with the 2017 AAP criteria (p &lt, 0.001). There was a statistically significant increase in children with high blood pressure in all age groups according to the new cut-off values. Notably, the diagnosis of hypertension according to 2017 AAP criteria had a greater positive association with Hepatic Steatosis (rho 0.2, p &lt, 0.001) and TG/HDL ratio (rho 0.125, p = 0.025). Conclusions: The 2017 AAP tables offer the opportunity to better identify overweight and obese children at risk for organ damage, allowing an earlier and more impactful prevention strategy to be designed.

Background: The increased intake of FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyol) rich foods has been suggested as a possible trigger of functional gastrointestinal disorders (FGIDs). Despite the high FODMAP content, the Mediterranean diet (MD) appears to have beneficial effects on health. Our aim was to evaluate whether the prevalence of FGIDs in different Mediterranean countries may be influenced by FODMAP consumption and adherence to the MD. Methods: A school-based, cross-sectional, multicenter study was performed in six countries in the Mediterranean area: Croatia, Greece, Israel, Italy, Macedonia, and Serbia. Subjects 4-18 years were examined in relation to their eating habits and the presence of FGIDs, using Rome IV criteria, 3-day food diaries and Mediterranean Diet Quality Index in Children and Adolescents (KIDMED) questionnaires. Results: We enrolled 1972 subjects between 4 and 9 years old (Group A), and 2450 subjects between 10 and 18 years old (Group B). The overall prevalence of FGIDs was 16% in Group A and 26% in Group B. FODMAP intake was significantly different among countries for both age groups. In both groups, no significant association was found between FGIDs and FODMAPs. Adherence to the MD in all countries was intermediate, except for Serbia, where it was low. In both groups, we found a statistically significant association between FGIDs and the KIDMED score (Group A: OR = 0.83, p < 0.001; Group B: OR = 0.93, p = 0.005). Moreover, a significant association was found between the KIDMED score and functional constipation (Group A: OR = 0.89, p = 0.008; Group B: OR = 0.93, p = 0.010) and postprandial distress syndrome (Group A: OR = 0.86, p = 0.027; Group B: OR = 0.88, p = 0.004). Conclusions: Our data suggest that the prevalence of FGIDs in the Mediterranean area is not related to FODMAP consumption, whereas adherence to the MD seems to have a protective effect.

Excess intake of energy, sugars, salt and saturated fats is an important causal factor of obesity and related non-communicable diseases. In order to help consumers to make healthy food choices, many European countries have developed proposals for “front-of-pack” food labeling, intended as an integration to the nutritional information provided by the mandatory nutritional declaration. Based on the European strategic program “Farm to Fork”, the intention is to achieve a harmonized front-of-pack label proposal by Q4 2022. Among the different proposals, the one which received most attention by experts and greater feedback by the EU member countries is the Nutri-Score, a tool based on an algorithm whereby a “quality” category ranging from A to E is assigned to each single food on a background colored from dark green to dark orange. As an alternative to Nutri-Score, the NutrInform Battery has been developed by Italy in association with a few other EU member states: this proposal is objectively alternative to the Nutri-Score proposal due to a different underlying philosophy, in particular for its informative and educational intent rather than purchase orientation. The present document, prepared by the Scientific Board and reviewed by the Scientific Council of the Italian Society of Human Nutrition, represents the scientific-based position of the Society in relation to the general theme of front-of-pack labeling and in particular to the dualism created between the Nutri-Score and NutrInform Battery proposals.

Bisphenol A (BPA) is an endocrine disruptor (ED) frequently used in food packaging. BPA is used as a monomer in the manufacture of some food packaging. This study aimed to evaluate the urinary BPA concentration in an Italian pediatric cohort, testing the levels of this ED over a period of 6 months, evaluating the effects of a diet regimen with a reduction of Plastic Food Packaging (PFP). One hundred thirty Italian children were enrolled and divided into two groups “School Canteen” and “No School Canteen.” The first group consumed one meal at school using a plastic-free service for 5 days/weeks, while the other group did not modify their normal meal-time habits. The BPA levels were tested in urine samples at three time points: T0, is the time before the application of the plastic-free regimen diet; T3, 3 months later; and T6, 6 months later. A reduction of urine BPA levels was detected in the “School Canteen” group. In particular, the reduction was significant analyzing both the intra (among the three testing times) group and inter (between “School Canteen” and “No School Canteen”) group variability. Our results show the effects of a diet regimen with a reduction of PFP, demonstrating a connection between urinary BPA levels and food packaging.

With the current obesity epidemic and the decline of fitness among school-aged children, the importance of obesity interventions to promote physical activity and healthy habits has become indisputable. The purpose of this study was to assess the efficacy of a school-based multicomponent intervention in increasing physical activity (PA) levels, actual physical abilities, and perceived physical abilities in clinical and nonclinical samples of overweight/obese boys and girls aged 10–12 years. The clinical intervention group (n = 35) participated in a 7-month after-school program in addition to curricular physical education lessons, while the nonclinical control group (n = 29) received usual curricular lessons. Measures included levels of PA and fitness and individual’s perceptions of physical ability. After treatment, the intervention group showed improved PA levels, perceived physical ability, and throwing and jumping task performances compared to the control group. Results indicate that a multicomponent program can improve levels of PA, fitness, and perceived competence of overweight participants. Findings highlight the importance of a comprehensive healthy lifestyle program that includes physical, psychosocial, and behavioral factors and suggest practical implications for educators, trainers, and teachers in identifying best practices targeting childhood obesity.

Because it is involved in calcium homeostasis, vitamin D is a prohormone with many implications for health, especially bone health. Hypovitaminosis D is considered pandemic worldwide, with important health health consequences. The aim of our study was to evaluate vitamin D levels in children living in a southern region of Italy with high exposure to sunlight for at least 5 mo a year along with contributing factors.A total of 1484 children and adolescents (age 0.02-17.74 y) living in the Apulia region (Southern Italy) were studied. Serum 25-hydroxyvitamin D (25[OH]D) concentrations were assessed and vitamin status defined as follows: deficiency with serum 25(OH)D20 ng/mL, insufficiency from 20 to 29.9 ng/mL, and sufficiency with serum 25(OH)D from 30 to 100 ng/mL.The median serum 25(OH)D levels were 20.2 ng/mL (interquartile range, 14.5-26.4 ng/mL): 48.9% of the overall population had 25(OH)D20 ng/mL and only 15% had sufficient 25(OH)D values. There was an inverse association between blood levels of 25(OH)D and age (P0.001, ρ: -0.113). Significant 25(OH)D variations were recorded according to the season in which blood samples were drawn, but even during summer only 32.6% of analyzed children had sufficient 25(OH)D levels.More than 80% of our population had 25(OH)D less than sufficiency cutoff levels. Results highlight a high prevalence of 25(OH)D deficiency in our area, even during summer. It is important to establish screening, supplementation guidelines, and pediatric cutoff levels to optimize vitamin D status in children, taking into account age, nutritional status, and seasonality.

The aims of this study were (1) to investigate whether 6−7-year-old children are accurate in perceiving their actual movement competence, and (2) to examine possible age- and gender-related differences. A total of 603 children (301 girls and 302 boys, aged 6 to 7 years) were assessed on the execution accuracy of six locomotor skills and six object control skills using the Test of Gross Motor Development (TGMD-2). The perceived competence of the same skills, plus six active play activities, was also gauged through the Pictorial Scale of Perceived Movement Skill Competence (PMSC-2). The factorial validity of the TGMD-2 and PMSC-2 scales was preliminarily ascertained using a Bayesian structural equation modeling approach. The relationships between the latent factors of the two instruments were then assessed. Gender and age differences were also examined. The factorial validity of the TGMD-2 and the PMSC-2 was confirmed after some adjustments. A subsequent analysis of the relationship between the latent factors (i.e., locomotor skills and object control) of the two instruments yielded very low estimates. Finally, boys and older children showed better competence in object control skills compared to their counterparts. Weak associations between actual and perceived competence suggest that inaccuracy in children’s perceptions can be likely due to a still limited development of cognitive skills needed for the evaluation of the own competence. From an applied perspective, interventions aimed at improving actual motor competence may also increase children’s self-perceived motor competence and their motivation toward physical activity. peerReviewed

Obesity is a multifactorial disease and the most primary risk of this is the development of type 2 diabetes. Numerous studies show that the effects of obesity on glucose metabolism result in the deterioration of glucose tolerance, the development of insulin resistance and the consequent damage of the secretory function of beta-cells. The type 2 diabetes is a worldwide health problem associated with obesity and sedentary lifestyle. As reported the American Diabetes Association, the physical activity is fundamental for type 2 diabetes patients, reducing blood pressure, cardiovascular events, and improve glucose metabolism and insulin sensitivity. In the light of these evidences, the aim of this study is to analyse the effects of healthy lifestyle, characterized by a correct diet and by adequate physical activity program in type 2 diabetes patients. We analysed 25 sedentary type 2 diabetes patients subjected to a correct diet and therapeutic treatment and 20 active type 2 diabetes patients subjected to a correct nutrition and a program of physical activity. We found an amelioration in biochemical and anthropometric parameters such as blood pressure, glycemia, glycated haemoglobin, body mass index (BMI). Given these results we can conclude that the physical activity has always been considered one of the cornerstones of type 2 diabetes therapy together with diet and pharmacotherapy. However, the results obtained show that physical activity deserves the same level of consideration as diet and insulin therapy even in the subject with type 2 diabetes.

Neurodevelopmental disorders (NDDs) include diverse neuropathologies characterized by abnormal brain development leading to impaired cognition, communication and social skills. A common feature of NDDs is defective synaptic plasticity, but the underlying molecular mechanisms are only partially known. Several studies have indicated that people’s lifestyles such as diet pattern and physical exercise have significant influence on synaptic plasticity of the brain. Indeed, it has been reported that a high-fat diet (HFD, with 30–50% fat content), which leads to systemic low-grade inflammation, has also a detrimental effect on synaptic efficiency. Interestingly, metabolic alterations associated with obesity in pregnant woman may represent a risk factor for NDDs in the offspring. In this review, we have discussed the potential molecular mechanisms linking the HFD-induced metabolic dysfunctions to altered synaptic plasticity underlying NDDs, with a special emphasis on the roles played by synaptic protein synthesis and mitochondrial functions.

The obesity epidemic and the decline of fitness among children highlights the need for suitable interventions designed to promote Physical Activity (PA) and healthy habits. The purpose of our pilot study was to assess the feasibility of a school-based program among overweight and obese children, by examining changes in their body composition, PA, physical fitness, and some psychosocial determinants of active behavior. An additional objective was to investigate the reciprocal relationship over time between PA and body image. Self-reported PA and health-related fitness tests were administered to 18 overweight and obese children (11.3 ± 0.4 years), before and after a 6-month intervention including nutritional education, skill-learning, playful physical activities, and exercise training. Participants were assessed on body composition, perceived physical ability, body image, and pleasant and unpleasant psychobiosocial states towards PA. After treatment, children showed decreased body mass index, body fat percentage, arm and waist circumferences, and skinfold thickness. Actual and perceived physical abilities, body image, and PA also improved over six months. Cross-lagged correlations suggest body image to be an antecedent to being physically active. Results showed that the multi-component school program may have sustainable benefits in reducing adiposity indicators and improving exercise adherence, physical fitness, and psychological well-being.

Regular physical activity and sport are able to modify the diffused neuro-immuno-endocrine-endothelial system. This emerges from careful scientific research that finds deep interconnections between the psyche, the nervous system, endocrine organs and the immune response. There is an interconnection between the psychoendocrine-immunological system and respiratory infections in athletes. The appearance of leucocytosis during intense physical activity can explain to us how strenuous exercise is responsible for a temporary depression of the immune system; indeed, the physical activity reduces the proliferative activity and function of T-lymphocytes and Natural Killer cells. This is associated with the influence of multiple factors such as age and gender. The respiratory mechanics during strenuous physical activity favours the dehydration of the mucous membranes, the modification of the mucociliary clearance and therefore the predisposition to infections, until the appearance of more complicated diseases such as neoplasms, as reported by data literature. In conclusion, regular and moderate exercise improves the immune system, reduces environmental and psychological stress, decreases the demand and administration of chemotherapy and immunosuppressants.

Aim The aim of the study was to investigate the level of cytokines in cultures of cow's milk protein- stimulated peripheral blood mononuclear cells of patients with cow's milk protein allergy. Material and Methods Eleven children with cow's milk protein allergy and 11 non-allergic controls were studied. Their peripheral blood mononuclear cells were cultured alone and in the presence of cow's milk α-lactalbumin; β-lactoglobulin; αS 1, αS 2, β, and κ-casein fraction mixtures; and a cow's protein mixture from whole milk. Production of cytokines, tumor necrosis factor-α, interleukin-10, and interleukin-12 were determined in culture supernatants. Results In cow's milk protein-stimulated peripheral blood mononuclear cell cultures of children with cow's milk protein allergy, tumor necrosis factor-α, interleukin-10, and interleukin-12 production was significantly higher than in non-allergic controls (p

Pediatric metabolic syndrome (MetS) is a well-recognized entity; however, there is no consensus on its exact value in predicting long-term cardiovascular (CV) risk. Hepatic steatosis (HS) is another emerging condition associated with pediatric obesity, and data have been reported suggesting a possible role of HS in CV risk linked to MetS. The aim of the present study was to evaluate the usefulness of HS and MetS cluster in predicting CV risk linked to pediatric obesity.We studied 803 overweight and obese children (395 girls and 408 boys, mean age 9.4 ± 2.5 y, body mass index z-score 2.2 ± 0.53) with complete clinical and biological assessment. MetS was defined using the modified criteria of the American Heart Association. The diagnosis and severity of the HS was based on ultrasound. To assess CV risk, all patients underwent ultrasonography to measure carotid intima-media thickness (cIMT)-a validated marker of subclinical vascular disease.The overall prevalence of MetS was 13.07%; HS was significantly higher in patients with MetS (40.9 versus 18.5%; P 0.001; odds ratio, 3.059; 95% confidence interval, 1.98-4.7). Spearman's correlation between HS grade and the number of MetS criteria met by each patient was significant (r = 0.285; P 0.001). No statistical difference was recorded in cIMT and cIMT z-scores between patients with or without MetS, until inclusion of HS as an additional criterion for the diagnosis of MetS. In this case, there was a significant difference in cIMT z-scores between the two groups. In multiple linear regression analysis, the cIMT z-score value was better predicted with HS grade and the MetS cluster (adjusted RHS could be used as additional criterion in detecting pediatric MetS phenotype at higher risk for long-term CV morbidity.

Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiological condition characterized by headache, nausea, vomiting, seizures, and visual disturbances with typical radiological features of symmetrical edema mostly involving the white matter in the occipital regions (1–2). PRES can develop in association with a wide array of clinical conditions, including systemic infections, hypertension, organ transplantation, and immunosuppression (especially with calcineurin inhibitors). Children who are on prolonged steroid therapy or on calcineurin inhibitor therapy in nephrotic syndrome (NS) are at risk of developing PRES (3–4). A 6-year-old Moroccan-boy, followed in his country for nephrotic syndrome, was hospitalized in our unit of pediatrics for severe generalized body edema, proteinuria (18600 mg/day), low serum albumin (0.9 g/L), high serum cholesterol (468 mg/dl). His arterial blood pressure value was 122/77 mmHg. We treated him with steroid intravenous, albumin supplementations and we continued cyclosporine. While his general conditions were improving, on the seventh day of hospitalization he developed headache, vomiting, dizziness, temporal blindness. A non-contrast computerized tomography was performed and it showed symmetrical hypodensities in parieto-occipital regions. His blood pressure was 132/71 mmHg. Then he developed two episodes of generalized tonic clonic convulsion, followed by unconsciousness. Magnetic resonance imaging (MRI) showed hyperintense signal in the parieto-occipital regions, and revealed bilateral cortical and subcortical white matter edema in parieto-occipital lobes The child was treated with antihypertensive medications, diuretic, steroids and immunosuppressant (cyclosporine A), thereafter he got no seizure and regained full consciousness and vision. His blood pressure was kept at normal range and urinary protein excretion gradually decreased. MRI performed two weeks later revealed no abnormality of the brain, which is a usual phenomenon in case of PRES The pathophysiology of PRES remains controversial, and two main hypotheses have been suggested; impaired cerebral autoregulation resulting in increased cerebral blood flow, and endothelial dysfunction with cerebral hypoperfusion (5–6). PRES must be managed carefully and its pathogenic factors should be suspected and recognized as soon as possible in order to properly treat the patient. In hypertension-related and drug-induced PRES, in fact, effective management includes prompt withdraw of offending agent, aggressive control of blood pressure, timely anti-convulsant therapy. In our case, hypertension was undoubtedly an important cause, but we were uncertain whether cyclosporine also played a pathogenic role. PRES should be always considered in the differential diagnosis of a child with idiopathic nephrotic syndrome, headache and visual disturbance.

BACKGROUND Iodine is an essential micronutrient for intellectual development in children. Information on iodine intakes based on 24-h urinary iodine excretion (UIE) is scant, because iodine status is only assessed by the measurement of urinary iodine concentration (UIC) in spot urine samples. OBJECTIVES The aim of our study was to evaluate the iodine intake of school-age children and adolescents, using UIE measurement in 24-h urine collections. METHODS The study population included 1270 healthy subjects (677 boys, 593 girls) aged 6-18 y (mean age ± SD: 10.3 ± 2.9) from 10 Italian regions. Daily iodine intake was estimated as UIE/0.92, based on the notion that $\sim$92% of the dietary iodine intake is absorbed. The adequacy of intakes was assessed according to the Dietary Reference Values for iodine of the European Food Safety Authority (EFSA). Body mass index (BMI) and UIC were also measured for each subject. RESULTS Based on the scientific opinion of EFSA, 600 of 1270 subjects (47.2%) had a lower than adequate iodine intake, with a higher prevalence among girls (54.6%) compared with boys (40.2%) (P

Background Functional gastrointestinal disorders (FGIDs) are characterized by chronic/recurrent gastrointestinal symptoms not related to organic disorders. Due to the limited treatment options and to the perception of subjects with FGIDs suffering from a food intolerance, in recent years there has been an increase in the self-prescription of elimination diets, especially gluten free diet (GFD), for the treatment of these disorders. For this reason, we decided to perform this systematic review with the aim to evaluate the available evidence on the effects of a GFD on gastrointestinal symptoms, in subjects with FGIDs. Methods Cochrane Library and MEDLINE (via PubMed) databases were searched, from inception to March 2018, using the MeSH terms “functional gastrointestinal disorder OR irritable bowel syndrome AND gluten”. We included all the clinical trials published in English and evaluating the effects of a GFD in subjects with FGIDs diagnosed according to the Rome II, III, and IV criteria. Results Eleven trials were eligible (3 prospective trials, 8 single or double-blind placebo-controlled trials), with 10/11 trials including adult subjects with irritable bowel syndrome (IBS) or FGIDs. Most of the prospective studies found an effect of GFD on gastrointestinal symptoms control. Nevertheless, 1 trial failed to find an association between gluten and GI symptoms when FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) content was simultaneously reduced in the diet, and 2 trials reported a worsening of symptoms during placebo administration. The results of the different trials are difficult to compare due to discrepancies in the study protocols regarding the amount and type of gluten administered, the duration of the gluten challenge, the type of placebo used, and the duration of the challenge itself. Conclusions According to our results, gluten may contribute to the occurrence of gastrointestinal symptoms in patients with FGIDs, particularly in those with IBS. Nevertheless, the results of the currently available trials are difficult to compare due to the lack of standardization in the study designs. For this reason, it is still not possible to recommend the use of the GFD in the routine management of FGIDs.

The accumulation of adipose tissue represents one of the characteristics of obesity, increasing the risk of developing correlated obesity diseases such as cardiovascular disease, type 2 diabetes, cancer, and immune diseases. Visceral adipose tissue accumulation leads to chronic low inflammation inducing an imbalanced adipokine secretion. Among these adipokines, Adiponectin is an important metabolic and inflammatory mediator. It is also known that adipose tissue is influenced by Orexin-A levels, a neuropeptide produced in the lateral hypothalamus. Adiponectin and Orexin-A are strongly decreased in obesity and are associated with metabolic and inflammatory pathways. The aim of this review was to investigate the involvement of the autonomic nervous system focusing on Adiponectin and Orexin-A after bariatric surgery. After bariatric surgery, Adiponectin and Orexin-A levels are strongly increased independently of weight loss showing that hormone increases are also attributable to a rearrangement of metabolic and inflammatory mediators. The restriction of food intake and malabsorption are not sufficient to clarify the clinical effects of bariatric surgery suggesting the involvement of neuro-hormonal feedback loops and also of mediators such as Adiponectin and Orexin-A.

Aim No data are available on caffeine consumption among Italian adolescents. We investigated caffeine intake from coffee, soft drinks and energy drinks in a sample of Italian adolescents and determined if they exceeded the recommended limits. Methods The study comprised 1213 adolescents with a mean age of 15.1 years (range 12–19) from four schools in Foggia, southern Italy. Caffeine intake was assessed using an anonymous self-reported questionnaire during the 2013/2014 school year. We calculated the percentage of daily caffeine consumers, their mean intake of caffeine from beverages and the contribution of each beverage category to the total caffeine intake. Results Approximately 76% of the sample consumed caffeine every day, amounting to 125.5 ± 69.2 mg/day and 2.1 ± 1.2 mg/kg/day. When we applied the reference values from the Academy of Pediatrics, we found that 46% of the adolescents exceeded the recommended upper limits. Coffee was the most frequently consumed caffeinated drink and the main contributor to daily caffeine intake. Conclusion More than three quarters (76%) of the Italian adolescents in our study drank coffee on a daily basis and nearly half (46%) exceeded the recommended upper limits. Strategies are needed to reduce caffeine consumption by adolescents.

none 34 no Background: Intestinal failure (IF) is the reduction in functioning gut mass below the minimal level necessary for adequate digestion and absorption of nutrients and fluids for weight maintenance in adults or for growth in children. There is a paucity of epidemiologic data on pediatric IF. The purpose of this study was to determine the prevalence, incidence, regional distribution and underlying diagnosis of pediatric chronic IF (CIF) requiring home parenteral nutrition (HPN) in Italy. Methods: Local investigators were selected in 19 Italian centers either of reference for pediatric HPN or having pediatric gastroenterologists or surgeons on staff and already collaborating with the Italian Society for Pediatric Gastroenterology, Hepatology and Nutrition with regard to IF. Data requested in this survey for children at home on Parenteral Nutrition (PN) on 1 December 2016 included patient initials, year of birth, gender, family’s place of residence and underlying diagnosis determining IF. Results: We recorded 145 CIF patients on HPN aged ≤19 years. The overall prevalence was 14.12/million inhabitants (95% CI: 9.20–18.93); the overall incidence was 1.41/million inhabitant years (95% CI: 0.53–2.20). Conclusion: Our survey provides new epidemiological data on pediatric CIF in Italy; these data may be quantitatively useful in developing IF care strategy plans in all developed countries. open Diamanti, Antonella; Capriati, Teresa; Gandullia, Paolo; Dileo, Grazia; Lezo, Antonella; Lacitignola, Laura; Spagnuolo, Mariaimmacolata; Gatti, Simona; D’antiga, Lorenzo; Verlato, Giovanna; Roggero, Paola; Amarri, Sergio; Baldassarre, Mariaelisabetta; Cirillo, Francesco; Elia, Domenica; Boldrini, Renata; Campanozzi, Angelo; Catassi, Carlo; Aloi, Marina; Romano, Claudio; Candusso, Manila; Cecchi, Nicola; Bellini, Tommaso; Tyndall, Elaine; Fusaro, Fabio; Caldaro, Tamara; Alberti, Daniele; Gamba, Piergiorgio; Lima, Mario; Bagolan, Pietro; De Goyet, Jean De Ville; Dall’oglio, Luigi; Spada, Marco; Grandi, Francesca Diamanti, Antonella; Capriati, Teresa; Gandullia, Paolo; Dileo, Grazia; Lezo, Antonella; Lacitignola, Laura; Spagnuolo, Mariaimmacolata; Gatti, Simona; Dâ antiga, Lorenzo; Verlato, Giovanna; Roggero, Paola; Amarri, Sergio; Baldassarre, Mariaelisabetta; Cirillo, Francesco; Elia, Domenica; Boldrini, Renata; Campanozzi, Angelo; Catassi, Carlo; Aloi, Marina; Romano, Claudio; Candusso, Manila; Cecchi, Nicola; Bellini, Tommaso; Tyndall, Elaine; Fusaro, Fabio; Caldaro, Tamara; Alberti, Daniele; Gamba, Piergiorgio; Lima, Mario; Bagolan, Pietro; De Goyet, Jean De Ville; Dallâ oglio, Luigi; Spada, Marco; Grandi, Francesca

Introduction the prevalence of malnutrition in children and its impact on clinical outcomes is underrecognized by clinicians in Italy as well as worldwide. A novel definition of pediatric malnutrition has been recently proposed by a working group of the Academy of Nutrition and Dietetics and American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.), based on the correlation between illness and the use of zscores of anthropometric measurements. Aim to investigate the prevalence of malnutrition and related nutritional support among hospitalized children in Italy, in a nationwide survey performed in a single day (16/4/2015). Methods an open access website (http://nday.biomedia.net) was used to collected data from 73 hospitals and 101 wards in 14 Italian regions (1994 patients). Anonymous information was collected on hospitals' characteristics, patient's anthropometry, admission diagnosis, presence of chronic diseases and use of nutritional support: oral nutritional supplements (ONS), enteral nutrition (EN) or parenteral nutrition (PN). Z-scores of anthropometric measurements, calculated with Epi Info 7.1.5, defined nutritional status: wasting was identified by BMI or Weight-for-Length z-score (

Background Infant colic (IC) is a prevalent physiological event of infants, which can disrupt the child's home environment. We aimed to investigate the effectiveness of a mixture of Matricariae chamomilla L., Melissa officinalis L. and tyndallized Lactobacillus acidophilus (HA122) compared with Lactobacillus reuteri DSM 17938 and with simethicone for the treatment of IC. Methods A multicenter randomized comparative study was conducted in infants with colic, according to Rome III criteria, who were randomly assigned to receive M. chamomilla L., M. officinalis L. and tyndallized L. acidophilus (HA122) (Colimil® Plus®; Milte Italia Spa, Milan, Italy) (Group A), L. reuteri DSM 17938 (Group B) and simethicone (Group C). Treatment was given to subjects for 28 days. Key Results One-hundred and seventy-six patients completed the study. Mean daily crying time at day 28 was significantly lower in group A (−44, 95% CI: −58 to −30, P

Background: Small bowel transplantation has now become a recognized treatment of irreversible, permanent, and subtotal intestinal failure. Objective: The aim of this study was to assess intestinal absorption at the time of weaning from parenteral nutrition in a series of children after intestinal transplantation. Design: Twenty-four children (age range: 14–115 mo) received intestinal transplantation, together with the liver in 6 children and the colon in 16 children. Parenteral nutrition was slowly tapered while increasing enteral tube feeding. The absorption rate was measured from a 3-d stool balance analysis performed a few days after the child had weaned from parenteral nutrition to exclusive enteral tube feeding. Results were analyzed according to the resting energy expenditure (REE; Schofield formula). Results: All children were weaned from parenteral nutrition between 31 and 85 d posttransplantation. Median intakes were as follows: energy, 107 kcal $ kg 21 $ d 21 (range: 79–168 kcal $ kg 21 $ d 21 ); lipids, 39 kcal $ kg 21 $ d 21 (range: 20–70 kcal $ kg 21 $ d 21 ); and nitrogen, 17 kcal $ kg 21 $ d 21 (range: 11–27 kcal $ kg 21 $ d 21 ). Median daily stool output was 998 mL/d (range: 220–2025 mL/d). Median absorption rates were 88% (range: 75–96%) for energy, 82% (range: 55–98%) for lipids, and 77% (range: 61–88%) for nitrogen. The ratios for ingested energy to REE and absorbed energy to REE were 2.2 (range: 1.6–3.6) and 1.8 (range: 1.3–3.3), respectively. Conclusion: These data indicate a suboptimal intestinal graft absorption capacity with fat malabsorption, which necessitates energy intakes of at least twice the REE.

GOALS: We assessed the efficacy of a probiotic mixture of Bifidobacterium infantis M-63, breve M-16V, and longum BB536 in improving abdominal pain (AP) and quality of life (QoL) in children with irritable bowel syndrome (IBS) and functional dyspepsia (FD). BACKGROUND: AP-associated functional gastrointestinal disorders, particularly IBS and FD, are common in pediatrics, and no well-established treatment is currently available. Although probiotics have shown promising results in adults, data in children are heterogeneous. STUDY: Forty-eight children with IBS (median age, 11.2 y; range, 8 to 17.9 y) and 25 with FD (age, 11.6 y; range, 8 to 16.6 y) were randomized to receive either a mixture of 3 Bifidobacteria or a placebo for 6 weeks. After a 2-week "washout" period, each patient was switched to the other group and followed up for further 6 weeks. At baseline and follow-up, patients completed a symptom diary and a QoL questionnaire. AP resolution represented the primary outcome parameter. RESULTS: In IBS, but not in FD, Bifidobacteria determined a complete resolution of AP in a significantly higher proportion of children, when compared with placebo (P=0.006), and significantly improved AP frequency (P=0.02). The proportion of IBS children with an improvement in QoL was significantly higher after probiotics than after placebo (48% vs. 17%, P=0.001), but this finding was not confirmed in FD. CONCLUSIONS: In children with IBS a mixture of Bifidobacterium infantis M-63, breve M-16V, and longum BB536 is associated with improvement in AP and QoL. These findings were not confirmed in FD subjects. Trial identifier: NCT02566876 (http://www.clinicaltrial.gov).

Objectives To assess the prevalence of irritable bowel syndrome (IBS) subtypes in childhood at diagnosis and their changes over 1 year. Study design This is an observational, prospective, multicenter study. Consecutive pediatric patients with IBS, according to Rome III criteria, were enrolled over a 1-year period. Parents recorded weekly stool frequency and consistency and gastrointestinal and extraintestinal symptoms in a diary. Stool consistency was scored according to the Bristol Stool Form Scale. Children were evaluated after 2, 3, 6, and 12 months. Results We enrolled 100 children with IBS (median age 9.9 years, range 4.2-16.7 years, 52 girls and 48 boys). At time of enrollment, constipation-IBS was the prevalent subtype (45%), with a prevalence of girls at 62% (P < .005); diarrhea-IBS was reported in 26% of children, with a prevalence of boys at 69% (P < .005); and alternating-IBS was described in 29% of children, without a difference between sexes. During the follow-up, 10% of patients changed their IBS subtypes at 2 months, 9% at 3 months, 7% at 6 months, and 6.3% at 12 months. Twenty-four percent of patients changed IBS subtype between the time of enrollment and 12 months. Conclusions Constipation-IBSis the prevalent subtype in children, with a higher frequency in girls. Inboys, diarrhea-IBS is the most common subtype. It is important to acquire knowledge about IBS subtypes to design clinical trials that may eventually shed new light on suptype-specific approaches to this condition.

Pediatric care in Italy has been based during the last 40 years on the increased awareness of the importance of meeting the psychosocial and developmental needs of children and of the role of families in promoting the health and well-being of their children. The pediatric health care system in Italy is part of the national health system. It is made up of 3 main levels of intervention: first access/primary care, secondary care/hospital care, and tertiary care based on specialty hospital care. This overview will also include a brief report on neonatal care, pediatric preventive health care, health service accreditation programs, and postgraduate training in pediatrics. The quality of the Italian child health care system is now considered to be in serious danger because of the restriction of investments in public health caused both by the 2008 global and national economic crisis and by a reduction of the pediatric workforce as a result of progressively insufficient replacement of specialists in pediatrics.

Excess salt intake impacts on blood pressure (BP) and the pathogenetic mechanisms of atherosclerosis predisposing to stroke and other cardiovascular disorders. The influence of salt starts early in life. Two randomized controlled trials in newborn infants suggest a direct association between dietary sodium intake and BP since the first few months of life. Newborn infants display aversion to the salt taste to develop a "preference" for salt only at age 2-3 years, in part in relation to post-natal events: this preference might be associated with later development of hypertension. The amount of sodium to be retained by an infant for proper physiological growth is largely covered by breast feeding (or low sodium formula milk) in the first six months, and later on by the gradual implementation of complementary feeding, without the need for any added salt upon food preparation. Given the lack of dose-dependence data, reference nutrient intakes (RNI) or adequate intakes (AI) for sodium have been established by national health institutions in various countries. The U.K. RNI was set at 242 mg a day for infants 0-6 months with gradual increase to 0.5 g up until age 3. The U.S. AI is somewhat lower for age 0-6 months but larger for age 1-3 years. According to a recent report, the average sodium intake in U.S. children is close to the AI up to age 2 years, to become progressively greater exceeding the Institute of Medicine recommendation later on.

Garganica goat milk was characterized for protein composition and the impact of milk protein mixture, casein and β-lactoglobulin fraction on cytokine production by cultured peripheral blood mononuclear cells from infants with cow's milk protein allergy. Bulk milk samples were collected in a dairy goat farm located in the Gargano area (Southern Italy), cow milk was used as control. Ten patients with cow's milk protein allergy (6 males; mean age 8.4 ± 6.4 months) and ten non-allergic control subjects (6 males; mean age 7.4 ± 3.1 months) were consecutively included in the study. Although the amount of total casein was comparable in cow and goat milk (56.08% vs . 55.33%, respectively) the distribution of principal casein fractions was different according to species. α-CN on total casein was more than 50% both in raw and pasteurized cow milk whereas it was always lower than 40% in goat milk and an opposite trend was observed for β-CN. Production of tumor necrosis factor-α after exposure to goat milk casein and β-lactoglobulin was lower than after exposure to the same fractions from cow milk. Goat milk induced higher levels of regulatory interleukin-10 by peripheral blood mononuclear cells than cow milk. Results on tumor necrosis factor-α evidenced that it is important to test the immune reactivity against each protein fraction before considering goat milk as a safe substitute for feeding infant with cow's milk protein allergy.
