Abstract
AbstractThe aim of this review is to describe adolescent nutritional requirements from a scientific, nutritional, and psychosocial point of view, emphasizing the main risks of malnutrition at this age. Currently, too many teenagers are alone at home and prepare their own meals. The influence of friends replaces parental rules. The habits of adolescents are characterized by a tendency to skip meals, especially breakfast, and, less frequently, the midday meal; to purchase carry-out meals away from home; to consume snacks, especially sweets; to eat at fast food restaurants, almost always with high-calorie content; and to eat fried foods, soft drinks, and sweets. Toxic habits, such as smoking, alcohol, and drugs, interfere with a healthy diet, as well. Physical activity usually decreases during adolescence, particularly in girls. The lack of physical activity is due to a precarious knowledge of the benefits associated with practicing physical activity, low motivation, time constraints, and, in many cases, the lack of adequate facilities. Adolescents interested in a body image in accordance with modern ideals follow restrictive and unbalanced diets without any nutritional basis, which they themselves planned. These behaviors increase the risk of nutritional alterations, such as noncompliance with nutritional requirements, meal pattern irregularities, nutritional problems due to low nutrient intake, and self-esteem issues and frustration. In general, in this age group, there is an increase in protein consumption and salt content, often with a supply of unbalanced nutrients, high-fat diets (35–50% of total calories), and low polyunsaturated/saturated fat ratio. In addition, adolescents consume a low level of complex carbohydrates, fiber, fruits, and vegetables.

Abstract
PURPOSE The relationships between gut microbiota and obesity-related co-morbidities have been increasingly recognized. Low-grade inflammation may be the main factor in the pathogenesis of such disorders. We investigated the effect of the potential probiotic Bifidobacterium pseudocatenulatum CECT 7765 on cardiometabolic risk factors, inflammatory cytokines and gut microbiota composition in obese children with insulin resistance. METHODS The study included 48 obese children (10-15 years old) with insulin resistance. They received dietary advice and were assigned to take the capsules with or without probiotic (109-10 CFU) daily for 13 weeks. Clinical, biochemical and gut microbiome measurements were made at baseline and at the end of the intervention. RESULTS There was a significant improvement in body mass index in all children after the intervention, suggesting that weight changes are related to the dietary advice. A significant decrease in circulating high-sensitive C-reactive protein (P = 0.026) and monocyte chemoattractant protein-1 (P = 0.032) and an increase in high-density lipoprotein cholesterol (P = 0.035) and omentin-1 (P = 0.023) in children receiving probiotic supplementation were observed compared to the control group. Regarding gut microbiota, probiotic administration significantly increased the proportion of the Rikenellaceae family members, particularly of the Alistipes genus. CONCLUSIONS The beneficial effects of the intervention on inflammatory markers and lipid profile suggest that B. pseudocatenulatum CECT 7765 intake together with dietary recommendations can improve inflammatory status in children with obesity and insulin resistance. These effects are parallel to increases in bacterial groups associated with a lean phenotype. The modulation of gut microbiota with probiotic supplementation can be considered an effective tool to ameliorate some obesity-related disorders in children.

Abstract
AbstractNutrition is one of the modifiable factors that contributes to bone accrual during childhood and adolescence, a critical period to prevent adult osteoporosis. Calcium and vitamin D seem to be the most important nutrients for optimal bone growth. Requirements for calcium intake are different among countries and organizations, and exact recommendations are difficult to determine since other dietary factors directly affect calcium metabolism, such as salt intake and vitamin D levels. Some scientists have suggested that the actual calcium requirements are overestimated and that increased dairy intake does not necessarily translate to better bone health in adults. Moreover, calcium can be obtained from other natural foods, such as cruciferous vegetables (turnip greens, broccoli rabe, kale, broccoli, and cabbage), endive, sesame seeds, legumes, almonds, calcium-fortified vegetable beverages, and canned sardines. Vitamin D should be obtained from food combined with appropriate sun exposure, and if that is not enough, vitamin D supplements can be used. Diets comprised a complex combination of nutrients and foods, and dietary patterns in children and adolescents play a key role in bone formation. A dietary pattern that is high in vegetables and fruits and low in processed foods (containing large amounts of added sugar and salt) is necessary to achieve optimal bone formation. Finally, physical activity, particularly activities that apply large forces, is even more important than dietary factors to contribute to bone accrual.

Abstract
A bidirectional communication between the gut and the brain (gut-brain axis) is well recognized with the gut microbiota viewed as a key regulator of this cross-talk. Currently, a body of preclinical and to a lesser extent epidemiological evidence supports the notion that host-microbe interactions play a key role in brain development and function and in the etiology of neurodevelopmental disorders. Early life events and shifts away from traditional lifestyles are known to impact gut microbiota composition and function and, thereby, may increase the risk of developing neurodevelopmental disorders. Attention deficit hyperactivity disorder (ADHD) is nowadays the most prevalent neurodevelopmental disorder. Despite many years of research its etiology is unclear and its diagnosis and treatment are still challenging. Different factors reported to be associated with the risk of developing ADHD and/or linked to different ADHD manifestations have also been linked to shifts in gut microbiota composition, suggesting a link between the microbiota and the disorder. Evidence from preliminary human studies also suggests that dietary components that modulate gut microbiota may also influence ADHD development or symptoms, although further studies are warranted to confirm this hypothesis. Here, we firstly review the potential mechanisms by which the gut microbiota may regulate the brain-gut axis and influence behavior and neurodevelopmental disorders. Secondly, we discuss the current knowledge about the different factors and dietary components reported to be associated with the risk of developing ADHD or its manifestations and with shifts in gut microbiota composition. Finally, we briefly highlight the need to progress our understanding regarding the role of the gut microbiota in ADHD, since this could open new avenues for early intervention and improved management of the disease.

Abstract
The last decade has witnessed a growing appreciation of the fundamental role played by an early assembly of a diverse and balanced gut microbiota and its subsequent maintenance for future health of the host. Gut microbiota is currently viewed as a key regulator of a fluent bidirectional dialogue between the gut and the brain (gut-brain axis). A number of preclinical studies have suggested that the microbiota and its genome (microbiome) may play a key role in neurodevelopmental and neurodegenerative disorders. Furthermore, alterations in the gut microbiota composition in humans have also been linked to a variety of neuropsychiatric conditions, including depression, autism and Parkinson’s disease. However, it is not yet clear whether these changes in the microbiome are causally related to such diseases or are secondary effects thereof. In this respect, recent studies in animals have indicated that gut microbiota transplantation can transfer a behavioral phenotype, suggesting that the gut microbiota may be a modifiable factor modulating the development or pathogenesis of neuropsychiatric conditions. Further studies are warranted to establish whether or not the findings of preclinical animal experiments can be generalized to humans. Moreover, although different communication routes between the microbiota and brain have been identified, further studies must elucidate all the underlying mechanisms involved. Such research is expected to contribute to the design of strategies to modulate the gut microbiota and its functions with a view to improving mental health, and thus provide opportunities to improve the management of psychiatric diseases. Here, we review the evidence supporting a role of the gut microbiota in neuropsychiatric disorders and the state of the art regarding the mechanisms underlying its contribution to mental illness and health. We also consider the stages of life where the gut microbiota is more susceptible to the effects of environmental stressors, and the possible microbiota-targeted intervention strategies that could improve health status and prevent psychiatric disorders in the near future.

Abstract
BACKGROUND Recent data suggest that retinol-binding protein 4 (RBP4) gene variants could be associated with a risk of obesity and its co-morbidities, such as metabolic syndrome, which increases the risk of developing type 2 diabetes mellitus and cardiovascular disease. OBJECTIVES The present study examined the potential association of RBP4 single nucleotide polymorphisms (SNPs) with childhood obesity and its metabolic complications. METHODS Four RBP4 SNPs, rs3758538 (3944A>C), rs3758539 (4406G>A), rs12265684 (12177G>C) and rs34571439 (14684T>G), were genotyped in a population of 180 Spanish Caucasian children (97 obese and 83 normal-weight children). Association of RBP4 SNPs with obesity, metabolic risk factors (blood pressure, triglycerides, high-density lipoprotein cholesterol, insulin resistance) and markers of vascular inflammation, such as high-sensitive C-reactive protein (hs-CRP), was tested. RESULTS We found SNP rs3758538 to be associated with obesity (p = 0.007). Specifically, each copy of the minor allele C was associated with an increased risk of obesity, by more than twofold, in respect of being homozygous for the major allele A (odds ratio = 2.4; 95% confidence interval = 1.2-4.8). The rs3758538 and rs34571439 RBP4 SNPs correlated with plasma RBP4 levels. The SNPs rs12265684 and rs34571439 correlated with plasma triglyceride levels. The rs34571439 was also associated to hs-CRP levels. Marginal association of RBP4 SNPs with plasma high-density lipoprotein levels (rs34571439), blood pressure (rs12265684) and insulin resistance (rs3758539) was also observed. CONCLUSIONS These findings suggest that childhood obesity may be associated with variations in RBP4 gene. The presence of selective SNPs in the RBP4 gene may account for metabolic complications.

Abstract
Numerous studies have shown that oxidative stress accelerates telomere shortening in several lung pathologies. Since oxidative stress is involved in the pathophysiology of α1-antitrypsin deficiency (AATD), we hypothesised that telomere shortening would be accelerated in AATD patients. This study aimed to assess telomere length in AATD patients and to study its association with α1-antitrypsin phenotypes.Telomere length, telomerase activity, telomerase reverse transcriptase (hTERT) expression and biomarkers of oxidative stress were measured in 62 children and teenagers (aged 2–18 years) diagnosed with AATD and 18 controls (aged 3–16 years).Our results show that intermediate-risk (MZ; SZ) and high-risk (ZZ) AATD patients have significantly shorter telomeres and increased oxidative stress than controls. Correlation studies indicate that telomere length was related to oxidative stress markers in AATD patients. Multiple hypothesis testing revealed an association between telomere length, telomerase activity, hTERT expression and AATD phenotypes; high-risk patients showed shorter telomeres, lower hTERT expression and decreased telomerase activity than intermediate-risk and low-risk patients.AATD patients show evidence of increased oxidative stress leading to telomere attrition. An association between telomere and α1-antitrypsin phenotypes is observed suggesting that telomere length could be a promising biomarker for AATD disease progression.

Abstract
BACKGROUND Some optic nerve diseases are silent and insidious. Recently, reduced thickness of retinal nerve fibre layer (RNFL) has been associated with increasing body mass index in adults. OBJECTIVES To investigate the association of childhood obesity with RNFL measured by optical coherence tomography imaging. METHODS Ninety-seven children aged 5-14 years classified according to standard deviation score of body mass index (SDS-BMI) were included. Parameters of metabolic risk, adipocytokines (leptin, adiponectin) and interleukin-6 were analyzed. All subjects underwent a comprehensive ophthalmologic examination with direct ophthalmoscopy. Evaluation of RNFL with optical coherence tomography of the head of the nerve was performed. RESULTS RNFL thickness on the average and inferior, superior and nasal quadrants were decreased in severely obese children (SDS-BMI > 4) with respect to the other groups. However, no statistically significant association was found between the different groups of children and RNFL thickness in the temporal quadrant. There was a significant inverse correlation of RNFL thickness with adiposity indices (P = 0.016), leptin (P = 0.029) and interleukin-6 (P = 0.030) in overweight and obese children. CONCLUSIONS These findings suggest that adiposity and obesity-related inflammatory factors may be associated with the loss of retinal ganglion cells in children.

Abstract
It is widely recognized that the intestinal microbiota plays a role in the initiation and perpetuation of intestinal inflammation in numerous chronic conditions. Most studies report intestinal dysbiosis in celiac disease (CD) patients, untreated and treated with a gluten-free diet (GFD), compared to healthy controls. CD patients with gastrointestinal symptoms are also known to have a different microbiota compared to patients with dermatitis herpetiformis and controls, suggesting that the microbiota is involved in disease manifestation. Furthermore, a dysbiotic microbiota seems to be associated with persistent gastrointestinal symptoms in treated CD patients, suggesting its pathogenic implication in these particular cases. GFD per se influences gut microbiota composition, and thus constitutes an inevitable confounding factor in studies conducted in CD patients. To improve our understanding of whether intestinal dysbiosis is the cause or consequence of disease, prospective studies in healthy infants at family risk of CD are underway. These studies have revealed that the CD host genotype selects for the early colonizers of the infant’s gut, which together with environmental factors (e.g., breast-feeding, antibiotics, etc.) could influence the development of oral tolerance to gluten. Indeed, some CD genes and/or their altered expression play a role in bacterial colonization and sensing. In turn, intestinal dysbiosis could promote an abnormal response to gluten or other environmental CD-promoting factors (e.g., infections) in predisposed individuals. Here, we review the current knowledge of host-microbe interactions and how host genetics/epigenetics and environmental factors shape gut microbiota and may influence disease risk. We also summarize the current knowledge about the potential mechanisms of action of the intestinal microbiota and specific components that affect CD pathogenesis.

Abstract
UNLABELLED Musculoskeletal injuries are a leading cause of paediatric injuries and emergency department visits in Western countries. Diagnosis usually involves radiography, but this exposes children without fractures to unnecessary ionising radiation. We explored whether infrared thermography could provide a viable alternative in trauma cases. We compared radiography and thermal images of 133 children who had been diagnosed with a trauma injury in the emergency unit of a Spanish hospital. As well as the thermal variables in the literature, we introduced a new quantifier variable, the size of the lesion. Decision tree models were built to assess the technique's accuracy in diagnosing whether a bone had been fractured or not. Infrared thermography had a sensitivity of 0.91, a specificity of 0.88 and a negative predictive value of 0.95. The new lesion size variable introduced appeared to be of main importance to the discriminatory power of the method. CONCLUSION The high negative predictive value of infrared thermography suggests that it is a promising method for ruling out fractures.

Abstract
BACKGROUND AND AIM Left ventricular (LV) hypertrophy and diastolic function have been found to be associated with obesity and hypertension in adults. However, there are scarce data about the association of obesity itself to cardiac alteration in children. The aim of this study was to detect early changes in LV structure and function in obese children and whether they are associated with the biomarkers of metabolic risk and endothelial activation. METHODS AND RESULTS A total of 130 children aged 7-16 years (88 obese and 42 normal-weight children) were studied. All children had normal resting blood pressure. Two-dimensional ultrasound with M-mode imaging was performed to assess the LV mass index (LVMi), calculated as LV mass/height(2.7), and the peak diastolic of pulmonary venous flow velocity (PVFD). Tissue Doppler imaging was used to analyze ventricular performance through the ratio of the transmitral peak early filling velocity to the early average diastolic peak myocardial velocity (E/E'). The indicators of metabolic control, inflammation, and endothelial cell activation were evaluated. Compared to the controls, the obese subjects had significantly higher LVMi and E/E' and lower PVFD values, the two latest being found especially in severely obese subjects. In the multivariate analysis, the parameters of diastolic function (E/E' and PVFD) were independently associated with obesity, apolipoprotein A1, soluble vascular cell endothelial molecule-1 (sVCAM-1), and retinol-binding protein 4 (RBP4). CONCLUSION An echocardiographic evaluation of diastolic function is a useful tool to detect early cardiac changes in obese children. Emergent cardiovascular risk markers such as apolipoprotein A1, RBP4, and sVCAM-1 are associated with the parameters of diastolic function.

Abstract
Adipose tissue is recognized as an endocrine organ that secretes bioactive substances known as adipokines. Excess adipose tissue and adipose tissue dysfunction lead to dysregulated adipokine production that can contribute to the development of obesity-related co-morbidities. Among the various adipokines, resistin, which was initially considered as a determinant of the emergence of insulin resistance in obesity, has appeared as an important link between obesity and inflammatory processes. Several experimental and clinical studies have suggested an association between increased resistin levels and severe conditions associated with obesity such as cardiovascular disease and malignancies. In this review, we present the growing body of evidence that human resistin is an inflammatory biomarker and potential mediator of obesity-associated diseases. A common pathway seems to involve the combined alteration of immune and inflammatory processes that favor metabolic disturbances, atherosclerosis and carcinogenesis. The mode of action and the signaling pathways utilized by resistin in its interactions with target cells could involve oxidative and nitrosative stress. Therefore, resistin could function as a key molecule in the complications of obesity development and could potentially be used as a diagnostic and prognostic marker.

Abstract
BACKGROUND A favorable effect over development of degenerative diseases is derived of an adecuate intake of fruit and vegetables, mainly due to their antioxidant compounds OBJECTIVES The goal of this study was to test the effect in vivo over oxidant status and inflammation in obese children of a novel food product made of dried apples enriched with mandarin juice by vacuum impregnation. METHODS A four-week intervention study was conducted in 41 obese children (> 2 standard deviation score-body mass index). Participants were instructed to follow their usual diet supplemented with 40 g/day of the developed product. Anthropometric parameters were determined including body mass index, waist circumference and estimations of body fat percentage using bioelectrical impedance. Dietary intake was assessed by questionnaire. Metabolic risk factors (blood pressure, lipid profile, glucose and insulin resistance) were recorded. To determine oxidant status, plasma total antioxidant capacity and 8-hydroxydeoxyguanosine, as marker of oxidative damage to DNA, were investigated. High-sensitive C-reactive protein, tumor necrosis factor-α, and interleukins 6 and 1-α were measured as inflammatory markers. Measurements were collected at baseline and at the end of the intervention period. RESULTS Significant improvement in systolic blood pressure and lipid profile after intervention period was noted. A significant increase in the antioxidant capacity of plasma (ABTS and FRAP assays) and reductions in DNA oxidative damage and inflammatory markers were also found. CONCLUSION Overall, adding the product to the diet contributes to ameliorate oxidant and inflammatory status in obese children and several risk factors for atherosclerosis.

Plasma resistin levels are associated with homocysteine, endothelial activation, and nitrosative stress in obese youths. Clin Biochem 2013; 47:44-8. [PMID: 24183883 DOI: 10.1016/j.clinbiochem.2013.10.021] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2013] [Revised: 10/09/2013] [Accepted: 10/19/2013] [Indexed: 02/06/2023]
Abstract
OBJECTIVE To evaluate whether serum resistin levels are related to cardiovascular risk in obese children. DESIGN AND METHODS Cross-sectional study of 110 children (40 normal weight and 70 severely obese). Clinical and biochemical parameters, including lipid profile, fasting glucose and insulin, and homocysteine, were determined. The levels of adipokines (adiponectin, leptin, and resistin), markers of inflammation (high-sensitivity C-reactive protein (hs-CRP)), endothelial activation (serum concentrations of soluble intercellular and vascular cellular adhesion molecule-1 (sICAM-1, sVCAM-1)), and oxidative/nitrosative stress (malondialdehyde and urinary nitrate/nitrite) were measured. RESULTS A partial correlation adjusted by gender, Tanner stage, and body mass index in obese children showed that resistin was significantly related to central obesity (p<0.002), insulin resistance (p<0.005), and homocysteine (p<0.001). No association was found with other metabolic risk factors or hs-CRP levels. Malondialdehyde (p<0.043) and sVCAM-1 (p<0.002) were positively correlated whereas urinary nitrate/nitrite was negatively correlated (p<0.007). In multiple regression analysis homocysteine, sVCAM-1, and urinary nitrate/nitrite remained independent determinants of resistin levels (R(2) adjusted=0.347, p=0.000). CONCLUSIONS Resistin could be considered as a promising marker for future cardiovascular disease in obese children.

Abstract
Serum retinol-binding protein 4 (RBP4) has been proposed as a metabolic risk factor in obesity. We found that RBP4 levels also were associated with liver enzymes and cystatin C. Oxidant stress is a significant feature in obese children with greater values of RBP4 that can mediate the development of comorbidities.

Abstract
The effect of a product made of dehydrated apples enriched with mandarin juice by vacuum impregnation on markers of oxidative stress (plasma antioxidant capacity, carbonyl groups (CGs), 8-hydroxydeoxyguanosine (8OHdG) and α-tocopherol) was tested in rats. Six groups of animals were studied: one group was fed a standard diet; two groups were supplemented with dehydrated apple either impregnated or not with mandarin juice throughout 28 days; and three groups (one unsupplemented and two supplemented) were additionally treated with tamoxifen (TAM) for 21 days used for induction of oxidative stress. The rats treated with TAM showed an increase in aminotransferases, CGs and 8OHdG. All of these effects were significantly decreased in the animals after apple snack consumption; the addition of mandarin juice into the apple mainly accounts for increased levels of α-tocopherol in plasma and liver. These findings suggest that the food product have a protective action against oxidative stress induced by TAM in rats.

Abstract
BACKGROUND After delivery and birth, mothers and neonates are exposed to oxidative stress. We tested whether supplementing the diet of breastfeeding mothers with non-alcoholic beer, a product rich in antioxidants, could improve their oxidative status and the antioxidant content of their milk. A prospective trial begun on Day 2 postpartum was conducted in mother-infant dyads. SUBJECTS AND METHODS Sixty breastfeeding mothers and their infants were allocated to either a control group (n=30) on a free diet or a study group (n=30) on a free diet supplemented with 660 mL of non-alcoholic beer/day. The oxidative status of the mothers' breastmilk, plasma, and urine and the infant's urine was analyzed on Days 2 and 30 postpartum. The before-after difference was compared within and between the groups. RESULTS The increase in antioxidant capacity and coenzyme Q10 content in the breastmilk of the study group at Day 30 was higher than in that of the control group (p<0.001). There was also a change in the oxidative status of the mothers' plasma in the supplemented group regarding the control group; higher values of total antioxidant capacity (p<0.05) and lower levels of 8-hydroxydeoxyguanosine (p<0.05), indicative of DNA oxidative damage, were found. These results indicate a positive effect of non-alcoholic beer supplementation on oxidative stress in mothers. However, no difference in oxidant markers was found in the infant's urine. CONCLUSIONS The consumption of non-alcoholic beer appears to enhance the antioxidant capacity of breastmilk and decrease oxidative damage in breastfeeding mothers.

Abstract
OBJECTIVE To examine vitamin D, parathyroid hormone, and serum calcium-phosphorus levels relationships to biomarkers of oxidative/nitrosative stress, inflammation, and endothelial activation, potential contributors for vascular complications in obese children. STUDY DESIGN Cross-sectional clinical study of 66 obese Caucasian children aged 7 to 14 years. Cardiovascular risk factors were assessed. Malondialdehyde and myeloperoxidase as measures of oxidative stress, and plasma nitrite+nitrate, urinary nitrate, and 3-nitrotyrosine as markers of nitrosative stress were measured. Adipocytokines, inflammatory molecules (high-sensitivity C-reactive protein, interleukin-6, and tumor necrosis factor-α), endothelial activation molecules (soluble intercellular adhesion molecule-1, soluble vascular cell adhesion molecule 1 [sVCAM-1]), E-selectin, and vascular endothelial growth factor were also investigated. Serum 25-hydroxy-cholecalciferol [25(OH)D], intact parathormone, and calcium-phosphorus levels were determined in these children and in a comparison group of 39 non-obese children. RESULTS Obese children had a significantly lower 25(OH)D level (P = .002) and a higher intact parathormone (P = .011) than non-obese children. Phosphorus and the calcium-phosphorus product were also significantly higher (P < .0001). Insufficient serum concentrations of 25(OH)D (<20 ng/mL) were detected in 5% of normal children and in 30% of the obese children. In the obese children with vitamin D insufficiency, malondialdehyde, myeloperoxidase, 3-nitrotyrosine, interleukin-6, and sVCAM-1 were substantially elevated. A partial correlation analysis showed an inverse relationship of 25(OH)D levels with 3-nitrotyrosine (r = -0.424, P = .001), and sVCAM-1 (r = -0.272, P = .032). CONCLUSIONS Insufficient 25(OH)D levels were detected in severely obese children with increased markers of oxidative/nitrosative stress, inflammation, and endothelial activation.
