Abstract
A minority of children born small for gestational age (SGA) may experience catch-up growth failure and remain short in adulthood. However, the underlying causes and mechanisms of this phenomenon are not yet fully comprehended. We reviewed the present state of research concerning the growth hormone-insulin-like growth factor axis and growth plate in SGA children who fail to achieve catch-up growth. Additionally, we explored the factors influencing catch-up growth in SGA children and potential molecular mechanisms involved. Furthermore, we considered the potential benefits of supplementary nutrition, specific dietary patterns, probiotics and drug therapy in facilitating catch-up growth.

Abstract
A regulated stress response is essential for healthy child growth and development trajectories. We conducted a cluster-randomized trial in rural Bangladesh (funded by the Bill & Melinda Gates Foundation, ClinicalTrials.gov NCT01590095) to assess the effects of an integrated nutritional, water, sanitation, and handwashing intervention on child health. We previously reported on the primary outcomes of the trial, linear growth and caregiver-reported diarrhea. Here, we assessed additional prespecified outcomes: physiological stress response, oxidative stress, and DNA methylation (N = 759, ages 1-2 years). Eight neighboring pregnant women were grouped into a study cluster. Eight geographically adjacent clusters were block-randomized into the control or the combined nutrition, water, sanitation, and handwashing (N + WSH) intervention group (receiving nutritional counseling and lipid-based nutrient supplements, chlorinated drinking water, upgraded sanitation, and handwashing with soap). Participants and data collectors were not masked, but analyses were masked. There were 358 children (68 clusters) in the control group and 401 children (63 clusters) in the intervention group. We measured four F2-isoprostanes isomers (iPF(2α)-III; 2,3-dinor-iPF(2α)-III; iPF(2α)-VI; 8,12-iso-iPF(2α)-VI), salivary alpha-amylase and cortisol, and methylation of the glucocorticoid receptor (NR3C1) exon 1F promoter including the NGFI-A binding site. Compared with control, the N + WSH group had lower concentrations of F2-isoprostanes isomers (differences ranging from -0.16 to -0.19 log ng/mg of creatinine, P < 0.01), elevated post-stressor cortisol (0.24 log µg/dl; P < 0.01), higher cortisol residualized gain scores (0.06 µg/dl; P = 0.023), and decreased methylation of the NGFI-A binding site (-0.04; P = 0.037). The N + WSH intervention enhanced adaptive responses of the physiological stress system in early childhood.

Abstract
Background & aims Metabolic disease prevalence has increased in many regions, and is closely associated with dyslipidemia. Rapid growth refers to a significant increase in growth velocity above the normal range, particularly in infants and children, and is highly prevalent in congenital deficiency infants. But the association between dyslipidemia and rapid growth remains controversial. We performed this meta-analysis to investigate the lipid profile in subjects with and without postnatal rapid growth, and to determine what are the confounding factors. Methods Medline, EMBASE, China National Knowledge Infrastructure Chinese citation database and WANFANG database were searched (last search in May 2021). Publication bias was examined by constructing funnel plots, Egger's linear regression test and Begg's rank correlation test. Results The fixed effects model would be adopted if I2 is less than 25%, otherwise random effects model would be used. There were 11 articles involved with a total of 1148 participants (539 boys and 609 girls, mean age=7.4 years). Pooled analysis found that rapid growth was negatively associated with high-density lipoprotein cholesterol (HDL-C) (weighted mean difference=-0.068, 95%CI [-0.117, -0.020]), but not associated with triglycerides (TG), total cholesterol (TC), or low-density lipoprotein cholesterol (LDL-C). Stratified analysis suggested that increased TG were found in rapid growth subjects from developing countries. Higher TC was observed for rapid growth participants of follow-up age ≤8 years old, rapid growth duration ≤2 years, preterm, low birth weight, and from developing countries. But decreased TC was observed in small for gestational age (SGA) rapid growth subjects. Decreased LDL-C had been documented in rapid growth subjects of follow-up age >8 years old, from developed countries, and SGA. At last, rapid growth groups had lower HDL-C in infants of rapid growth duration >2 years and from developed countries. Conclusion Rapid growth is associated with lipid profiles, particularly during early childhood, and this relationship is influenced by factors such as the duration of growth, the level of national development, and birth weight. These findings are significant for the development of strategies to prevent metabolic diseases.This review was registered in PROSPERO International Prospective Register of Systematic Reviews (www.crd.york.ac.uk/prospero/) with the registration number CRD42020154240.

Liver transcriptome profiling and functional analysis of intrauterine growth restriction (IUGR) piglets reveals a genetic correction and sexual-dimorphic gene expression during postnatal development. BMC Genomics 2020; 21:701. [PMID: 33032518 PMCID: PMC7545842 DOI: 10.1186/s12864-020-07094-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Accepted: 09/23/2020] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND Intrauterine growth restriction (IUGR) remains a major problem associated with swine production. Thus, understanding the physiological changes of postnatal IUGR piglets would aid in improving growth performance. Moreover, liver metabolism plays an important role in the growth and survival of neonatal piglets. RESULTS By profiling the transcriptome of liver samples on postnatal Days 1, 7, and 28, our study focused on characterizing the growth, function, and metabolism in the liver of IUGR neonatal piglets. Our study demonstrates that the livers of IUGR piglets were associated with a series of complications, including inflammatory stress and immune dysregulation; cytoskeleton and membrane structure disorganization; dysregulated transcription events; and abnormal glucocorticoid metabolism. In addition, the abnormal liver function index in the serum [alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total protein (TP)], coupled with hepatic pathological and ultrastructural morphological changes are indicative of liver damage and dysfunction in IUGR piglets. Moreover, these results reveal the sex-biased developmental dynamics between male and female IUGR piglets, and that male IUGR piglets may be more sensitive to disrupted metabolic homeostasis. CONCLUSIONS These observations provide a detailed reference for understanding the mechanisms and characterizations of IUGR liver functions, and suggest that the potential strategies for improving the survival and growth performance of IUGR offspring should consider the balance between postnatal catch-up growth and adverse metabolic consequences. In particular, sex-specific intervention strategies should be considered for both female and male IUGR piglets.

Abstract
BACKGROUND & AIMS Rapid growth in childhood and obesity are highly prevalent in congenital deficiency infants, but the associations between them remain controversial. This meta-analysis was performed to explore the effects of rapid growth on body mass index (BMI) and percent body fat (PBF), and to clarify potential confounders. METHODS A systematic search was performed using electronic databases including EMBASE (1985 to July 2019) and Medline (1966 to July 2019) for English articles. China National Knowledge Infrastructure Chinese citation database (CNKI) and WANFANG database were used to search articles in Chinese. Reference lists were also screened as supplement. All relevant studies that compare BMI or PBF between rapid group and control group were identified. The definition of rapid growth should be clearly specified. Means and standard deviations/95% confidence intervals (CIs) of BMI and PBF should be available. Relevant information was extracted independently by two reviewers. Study quality was reassessed using the Newcastle-Ottawa Scale. Publication bias and heterogeneity were detected. The random effect model was adopted for combined and stratified analysis. RESULTS About the effect of rapid growth on BMI, seventeen researches (4473 participants) involving 49 comparisons were included. Pooled analysis showed rapid group had higher BMI of 0.573 (95% CI, 0.355 to 0.791; P < 0.001). Stratified analyses revealed that catch-up weight gain, follow-up age >6 years old, rapid growth duration >2 years, full-term, comparing rapid growth SGA infants with control SGA infants, and from developed and developing countries, would all lead to higher BMI in rapid groups. About the effect of rapid growth on PBF, eleven researches (4594 participants) involving 37 comparisons were included. Pooled analysis showed rapid group had higher PBF of 2.005 (95% CI, 1.581 to 2.429; P < 0.001). Subgroup analyses suggested that catch-up weight gain, follow-up age ≤6 years old, rapid growth duration >2 years, full-term, comparing rapid growth SGA infants with control AGA infants, and participants from developing countries, would lead to increased PBF in rapid groups. CONCLUSION Rapid growth has a positive correlation with BMI and PBF. However, stratified analyses show that it is catch-up weight gain that lead to higher BMI and PBF, but not catch-up growth. In addition, rapid growth have long-term effect on BMI and short-term effect on PBF. Rapid growth duration longer than 2 years may increase the risk effect of rapid growth on BMI and PBF. But given that rapid growth would induce multiple health outcomes apart from BMI and PBF, the benefits and risks of rapid growth must be carefully considered and weighted.

Abstract
Adverse ecological and social conditions during early life are known to influence development, with rippling effects that may explain variation in adult health and fitness. The adaptive function of such developmental plasticity, however, remains relatively untested in long-lived animals, resulting in much debate over which evolutionary models are most applicable. Furthermore, despite the promise of clinical interventions that might alleviate the health consequences of early-life adversity, research on the proximate mechanisms governing phenotypic responses to adversity have been largely limited to studies on glucocorticoids. Here, we synthesize the current state of research on developmental plasticity, discussing both ultimate and proximate mechanisms. First, we evaluate the utility of adaptive models proposed to explain developmental responses to early-life adversity, particularly for long-lived mammals such as humans. In doing so, we highlight how parent-offspring conflict complicates our understanding of whether mothers or offspring benefit from these responses. Second, we discuss the role of glucocorticoids and a second physiological system-the gut microbiome-that has emerged as an additional, clinically relevant mechanism by which early-life adversity can influence development. Finally, we suggest ways in which nonhuman primates can serve as models to study the effects of early-life adversity, both from evolutionary and clinical perspectives.

Abstract
This study was conducted to investigate the effects of methionine restriction (MR) on growth performance, insulin sensitivity, and hepatic and muscle glucose metabolism in intrauterine growth retardation (IUGR) pigs at 49 and 105 d of age. At weaning (day 21), 30 female normal birth weight (NBW) piglets were fed control diets with adequate methionine (NBW-CON), whereas 60 female IUGR piglets were fed either the control diets (IUGR-CON) or MR diets which were 30% reduced in methionine (IUGR-MR) (n = 6 replicates (pens) with five piglets per replicate). At 49 and 105 d of age, one pig with a BW near to the mean of each replication was selected for biochemical analysis. Compared with NBW-CON pigs, IUGR-CON pigs exhibited lower relative daily gain (RDG) and homeostasis model assessment of insulin resistance (HOMA-IR) index at day 49 (P < 0.05), but higher RDG and HOMA-IR index at day 105 (P < 0.05). Hepatic phosphoenolpyruvate carboxykinase and glucose-6-phosphatase (G6Pase) activities were higher in IUGR-CON than NBW-CON pigs at both days 49 and 105 (P < 0.05), while hepatic glycogen synthase and glycogen phosphorylase activities were lower in IUGR-CON pigs at both two ages (P < 0.05). In addition, compared with NBW-CON pigs, IUGR-CON pigs (105-d old) had lower protein kinase B phosphorylation (PKB/Akt) in liver (P < 0.05), but not in muscle (P > 0.05). Compared with IUGR-CON pigs, IUGR-MR pigs had lower RDG at day 49, less blood glucose at day 105, and lower HOMA-IR index at both days 49 and 105 (P < 0.05). Additionally, compared with IUGR-CON pigs, MR decreased IUGR-MR pigs' hepatic G6Pase activities and increased their hepatic glycogen contents at day 105 (P < 0.05), as well as increased their hepatic and muscle PKB/Akt phosphorylation (P < 0.05). In conclusion, the ability of dietary MR to restrict IUGR pigs' growth and to reduce blood glucose appeared, respectively, in earlier and later period, but MR improved IUGR pigs' insulin sensitivity at both days 49 and 105.

Abstract
BACKGROUND The occurrence of osteoarthritis (OA) of the temporomandibular joint (TMJ) in juveniles could be associated with fluctuating levels of oestrogen and growth hormone (GH) during adolescence. OBJECTIVE To investigate extent of skeletal maturation and predicted adult height in adolescents with TMJ OA. METHOD In total, 155 adolescents (54 males, 101 females; mean age, 14.1 ± 2.0 years) were enrolled. Among them, 19 adolescents (CON) showed no sign of TMD, 50 adolescents exhibited signs of disc displacement but did not have TMJ OA (TMDnoOA), 23 adolescents exhibited the initial stage of TMJ OA (TMJOAini) and 63 adolescents exhibited the severe stage of TMJ OA (TMJOApro). TMJ OA was diagnosed based on the Research Diagnostic Criteria axis I and bone age was estimated using the Greulich-Pyle method. The height, weight and body mass index of participated adolescents were measured and statistically converted to z-scores. The predicted adult height and age of peak height velocity (APHV) were calculated using the BoneXpert® software. RESULTS In female adolescents, the differences between the chronological and bone ages were significantly higher and the z-score for height was significantly lower in the TMJOApro. Female adolescents with TMJOA exhibited a significantly shorter predicted adult height and earlier APHV than those in the CON and TMDnoOA. CONCLUSION The adolescents with TMJ OA exhibited premature skeletal maturations and short predicted adult stature, particularly the female adolescents.

Abstract
Stress is one of the commonest and underappreciated causes of reproductive frailty in women. The stress system leads to adaptive responses via mobilization of hormonal systems. Adaptability and resistance to stress are fundamental to life. The response to stressors depends on the type of stressor, the timing and duration of stress, the genetic predisposition, personality characteristics, and the way of coping with stress. The hypothalamic-pituitary-adrenal (HPA) axis has a direct inhibitory action on the hypothalamic-pituitary-ovarian (HPO) axis at multiple levels. Acute and chronic stress impairs reproduction, eventually acting on varying mechanisms. Undernutrition, over-training, and psychological stress contribute to hypothalamic amenorrhea via reduced HPO activity. In utero stress exposure is a significant predictor of subsequent adult telomere length. Some of the metabolic consequences of intrauterine growth restriction can be mitigated by ensuring early appropriate catch-up growth, while avoiding excessive weight gain if relative hypercortisolism is not installed. The effect of maternal stress on fetuses regarding fetal HPA axis responsiveness (increased or decreased) remains under investigation. Maternal stress and depression are associated with structural and functional changes of brain parts such as hippocampus. In utero stress modifies epigenetically components of the HPA axis which can be transmitted transgenerationally.

Abstract
Background: The aim of this study was to evaluate the effect of dydrogesterone in the outcome of idiopathic intrauterine growth restriction (IUGR). Materials and Methods: It is a double-blind randomized control clinical trial study that was done in Shahid Beheshti hospital of Isfahan during 2015–2016. In this study, 89 pregnant women with idiopathic IUGR fetus were selected and randomly divided into two intervention and control groups. Intervention group was treated with dydrogesterone 10 mg every 12 h for 2 weeks, while the control group received conventional management and treatment of IUGR, which also has been performed in the intervention group. Results: After 2 weeks of intervention, fetal weight was significantly increased in dydrogesterone group as compared to control group (2053.15 vs. 1736.36 g, P = 0.001); furthermore, we observed significant differences in the term of fetal abdominal circumference between the groups (27.25 vs. 25.92 cm, P = 0.006). Middle cerebral artery resistance index (0.67 vs. 0.83, P < 0.001) and uterine artery (UA) resistance index (0.68 vs. 0.81, P < 0.001) were significantly decreased in dydrogesterone group as compared to control group. Conclusions: Our results showed that dydrogesterone reduces resistance index of uterine artery and middle cerebral and increased fetal weight, while no sign of toxicity was observed. Dydrogesterone supplementation would have the potentiality to become a simple and economic means to prevent IUGR.

Abstract
Infants born with low birth weights (<2500 g, LBW), accounting for about 15 % of newborns, have a high risk for postnatal growth failure and developing the metabolic syndromes such as type 2 diabetes, CVD and obesity later in life. Improper nutrition provision during critical stages, such as undernutrition during the fetal period or overnutrition during the neonatal period, has been an important mediator of these metabolic diseases. Considering the specific physiological status of LBW infants, nutritional intervention and optimisation during early life merit further attention. In this review, the physiological and metabolic defects of LBW infants were summarised from a nutritional perspective. Available strategies for nutritional interventions and optimisation of LBW infants, including patterns of nutrition supply, macronutrient proportion, supplementation of amino acids and their derivatives, fatty acids, nucleotides, vitamins, minerals as well as hormone and microbiota manipulators, were reviewed with an aim to provide new insights into the advancements of formulas and human-milk fortifiers.

Abstract
BACKGROUND In children born small for gestational age (SGA) with catch-up growth, a higher risk of insulin resistance (IR) and cardiovascular diseases is noted. Ghrelin stimulates a growth hormone (GH) secretion and regulates lipid and carbohydrate metabolism. We assessed gherlin's influence on achieving normal height and the occurrence of metabolic complications in SGA children. METHODS Ghrelin, insulin-like growth factor type I (IGF-I), leptin, adiponectin, resistin, glucose, insulin and lipid concentrations were analysed in 134 prepubertal children in four groups: normal-height SGA, short SGA, normal-height born appropriate for gestational age (AGA) and short AGA. RESULTS Ghrelin and IGF-I concentrations were significantly higher while adiponectin - lower in normal-height SGA comparing to others. CONCLUSIONS The increased production of ghrelin and IGF-I seems to be an adaptive mechanism to achieve normal growth in SGA children. The significance of high ghrelin and low adiponectin concentrations, observed in normal-height prepubertal SGA children, requires elucidation, with reference to the development of metabolic complications.

Abstract
Soluble M6P/IGFIIR has the potential to be a significant carrier of IGF-II and mannose 6-P proteins in the circulation and play an important role as an antagonist to the cellular receptor. Evidence suggests that soluble receptor plays a role in fetal and childhood growth by opposing the growth stimulatory effects of IGF-II. Maternal serum levels of M6P/IGFIIR are elevated in late pregnancy and the IGF-II:soluble M6P/IGFIIR ratio in cord blood correlates strongly with weight at birth and placental weight suggesting an important role in fetal growth and development. However, elevated soluble receptor levels may also be indicative of disease in later life, such as liver cirrhosis and some tumor types and may be a useful marker for monitoring treatment and progression of the disease. Further investigation of the regulation of this soluble receptor in health and disease is required to fully elucidate its role in the circulation.

Abstract
The concept of the developmental origins of health and disease is based on studies by Barker et al. They proposed a hypothesis that undernutrition in utero permanently changes the body's structure, function, and metabolism in ways that lead to atherosclerosis and insulin resistance in later life. In addition, profound effects on the extent of body fatness and insulin sensitivity are demonstrated, if there is a "mismatch" between prenatal and postnatal environments. In previous studies, undernutrition in utero has been evaluated simply by birth weight itself or birth weight for gestational age, and the degree of mismatch has been estimated by postnatal rapid weight gain. Recently, we investigated subcutaneous fat accumulation in small-for-gestational-age infants and found that a rapid catch-up in skinfold thickness developed prior to the body weight catch-up. Furthermore, insulin-like growth factor-I and lipoprotein lipase mass concentrations also demonstrate rapid increase during the neonatal period with fat accumulation. Investigating the precise mechanisms of developmental origins of health and disease including mediating metabolic and hormonal factors may provide a new approach to prevent atherosclerosis and insulin resistance. Better management of undernutrition during gestation and neonatal growth during the early postnatal period is an important theme for future health.

Abstract
Low birth weight is associated with lower bone accrual in children and peak bone mass in adults. We assessed how different patterns of longitudinal fetal and early childhood growth influence bone properties at school age. In 5431 children participating in a population-based prospective cohort study, we measured fetal growth by ultrasound at 20 and 30 weeks gestation, and childhood growth at birth, 1, 2, 3, and 4 years of age. We analyzed these growth measurements in relation to total body (less head) BMD measured by DXA at age 6. We used conditional growth modeling; a technique which takes into account correlation between repeatedly measured growth measures. Our results showed that estimated fetal weight gain, femur length growth between 20 and 30 weeks of gestation, femur length growth between 30 weeks and birth, as well as all height and weight growth measurements from birth to 4 years of age were all positively associated with BMC, bone area (BA), and BMD (all p < 0.01). Fetal femur length growth between 30 weeks and birth was positively associated with BMC and BA (both p < 0.001), but not with BMD. Overall, childhood growth measurements exerted a larger influence on bone measures than fetal growth measures. The strongest effect estimate was observed during the first year of life. Children born small (<10th percentile) for gestational age (SGA) had lower BMC and BA, but not BMD, than children born appropriate for gestational age (AGA), whereas children born large (>90th percentile) for gestational age (LGA) had higher BMC and BA (all p < 0.001). These differences were no longer present in children showing subsequent accelerated and decelerated infant growth, respectively. We conclude that both fetal and childhood growth patterns are associated with bone mineral accrual, showing the strongest effect estimates in infancy. Compensatory infant growth counteracts the adverse consequences of fetal growth restriction on bone development.

Abstract
OBJECTIVE to evaluate changes in the biochemical profile of children treated or being treated for moderate or severe stunting in a nutrition recovery and education center. METHODS this was a retrospective longitudinal study of 263 children treated at this center between August of 2008 to August of 2011, aged 1 to 6 years, diagnosed with moderate (z-score of height-for-age [HAZ] < -2) or severe stunting (HAZ < -3). Data were collected on socioeconomic conditions, dietary habits, and biochemical changes, as well as height according to age. RESULTS the nutritional intervention showed an increase in HAZ of children with moderate (0.51 ± 0.4, p = 0.001) and severe (0.91 ± 0.7, p = 0.001) stunting during the monitoring. Increased levels of insulin-like growth factor 1 (IGF-1) (initial: 71.7 ng/dL; final: 90.4 ng/dL; p = 0.01) were also observed, as well as a reduction in triglycerides (TG) in both severely (initial: 91.8mg/dL; final: 79.1mg/dL; p = 0.01) and in moderately malnourished children (initial: 109.2mg/dL; final 88.7mg/dL; p = 0.01), and a significant increase in high-density lipoprotein cholesterol HDL-C only in the third year of intervention (initial: 31.4mg/dL; final: 42.2mg/dL). The values of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels remained high throughout the treatment (initial: 165.1mg/dL; final: 163.5mg/dL and initial: 109.0mg/dL; final: 107.3mg/dL, respectively). CONCLUSION the nutritional treatment for children with short stature was effective in reducing stunting and improving TG and HDL-C after three years of intervention. However, the levels of LDL-C and TC remained high even in treated children. It is therefore speculated that these changes may result from metabolic programming due to malnutrition.

Abstract
This article is part of a Special Issue "Energy Balance". The development of neuroendocrine regulation of food intake during early life has been shaped by natural selection to allow for optimal growth and development rates needed for survival. In vertebrates, neonates or early larval forms typically exhibit "feeding drive," characterized by a developmental delay in 1) responsiveness of the hypothalamus to satiety signals (e.g., leptin, melanocortins) and 2) sensitivity to environmental cues that suppress food intake. Homeostatic regulation of food intake develops once offspring transition to later life history stages when growth is slower, neuroendocrine systems are more mature, and appetite becomes more sensitive to environmental or social cues. Across vertebrate groups, there is a tremendous amount of developmental plasticity in both food intake regulation and stress responsiveness depending on the environmental conditions experienced during early life history stages or by pregnant/brooding mothers. This plasticity is mediated through the organizing effects of hormones acting on the food intake centers of the hypothalamus during development, which alter epigenetic expression of genes associated with ingestive behaviors. Research is still needed to reveal the mechanisms through which environmental conditions during development generate and maintain these epigenetic modifications within the lifespan or across generations. Furthermore, more research is needed to determine whether observed patterns of plasticity are adaptive or pathological. It is clear, however, that developmental programming of food intake has important effects on fitness, and therefore, has ecological and evolutionary implications.

Abstract
OBJECTIVE Developmental programming alters growth and metabolic outcome in children born small for gestational age (SGA). We explored insulin and glucose metabolism in SGA children treated with a fixed GH dose over 1 year. METHODS In the North European Small for Gestational Age Study (NESGAS), 110 short SGA children received GH at 67 µg/kg/day for 1 year. Insulin secretion was assessed by acute insulin response (AIR), insulin sensitivity (IS) by HOMA and disposition index (DI) by insulin secretion adjusted for IS. RESULTS First-year GH therapy led to increases in height and IGF-I standard deviation score (SDS), and reductions in IS (p < 0.0001). Compensatory increases in AIR (p < 0.0001) were insufficient and resulted in reduced DI (p = 0.032). Children in the highest IGF-I SDS tertile at baseline were the least insulin sensitive at baseline (p = 0.024) and 1 year (p = 0.006). IGF-I responses after 1 year were positively related to AIR (r = 0.30, p = 0.007) and DI (r = 0.29, p = 0.005). CONCLUSION In SGA children treated with a high GH dose for 1 year, baseline IGF-I levels were related to IS whilst gains in height and IGF-I responses were associated with insulin secretion. Defining heterogeneity in IGF-I in SGA children may be useful in predicting growth and metabolic response.

Abstract
The overall acceptance of pig models for human biomedical studies is steadily growing. Results of rodent studies are usually confirmed in pigs before extrapolating them to humans. This applies particularly to gastrointestinal and metabolism research due to similarities between pig and human physiology. In this context, intrauterine growth retarded (IUGR) pig neonate can be regarded as a good model for the better understanding of the IUGR syndrome in humans. In pigs, the induction of IUGR syndrome may include maternal diet intervention, dexamethasone treatment or temporary reduction of blood supply. However, in pigs, like in humans, circa 8% of neonates develop IUGR syndrome spontaneously. Studies on the pig model have shown changes in gut structure, namely a reduced thickness of mucosa and muscle layers, and delayed kinetic of disappearance of vacuolated enterocytes were found in IUGR individuals in comparison with healthy ones. Functional changes include reduced dynamic of gut mucosa rebuilding, decreased activities of main brush border enzymes, and changes in the expression of proteins important for carbohydrate, amino acids, lipid, mineral and vitamin metabolism. Moreover, profiles of intestinal hormones are different in IUGR and non-IUGR piglets. It is suggested that supplementation of the mothers during the gestation and/or the IUGR offspring after birth can help in restoring the development of the gastrointestinal tract. The pig provides presumably the optimal animal model for humans to study gastrointestinal tract structure and function development in IUGR syndrome.

Abstract
In developing countries, prenatal lipid-based nutrient supplements (LNSs) were shown to increase birth size; however, the mechanism of this effect remains unknown. Cord blood hormone concentrations are strongly associated with birth size. Therefore, we hypothesize that LNSs increase birth size through a change in the endocrine regulation of fetal development. We compared the effect of daily prenatal LNSs with multiple micronutrient tablets on cord blood hormone concentrations using a randomized, controlled design including 197 pregnant women from rural Burkina Faso. Insulin-like growth factors (IGF) I and II, their binding proteins IGFBP-1 and IGFBP-3, leptin, cortisol, and insulin were quantified in cord sera using immunoassays. LNS was associated with higher cord blood leptin mainly in primigravidae (+57%; P = 0.02) and women from the highest tertile of BMI at study inclusion (+41%; P = 0.02). We did not find any significant LNS effects on other measured cord hormones. The observed increase in cord leptin was associated with a significantly higher birth weight. Cord sera from small-for-gestational age newborns had lower median IGF-I (-9 μg/L; P = 0.003), IGF-II (-79 μg/L; P = 0.003), IGFBP-3 (-0.7 μg/L; P = 0.007), and leptin (-1.0 μg/L; P = 0.016) concentrations but higher median cortisol (+18 μg/L; P = 0.037) concentrations compared with normally grown newborns. Prenatal LNS resulted in increased cord leptin concentrations in primigravidae and mothers with higher BMI at study inclusion. The elevated leptin concentrations could point toward a higher neonatal fat mass.

Abstract
Intrauterine growth retardation (IUGR) is associated with increased prevalence, at the adult age, of central obesity, the metabolic syndrome, and its complications (type 2 diabetes and coronary heart disease). Programming of the corticotropic function is one of the mechanisms underlying the above-mentioned phenomenon. An increased passage of active glucocorticoids from the mother to the fetus can act, at the central nervous system level, to program an enhanced response to stress and, at the peripheral level, in adipose tissue to induce an increased local glucocorticoid exposure and sensitivity. In addition to an improvement of the health of pregnant women, early diagnosis of metabolic and hormonal disturbances is important in children with IUGR, in order to prevent a compensatory catch-up growth and its subsequent obesity, and to set up a therapeutic intervention against the deleterious consequences of hypercorticism.

Abstract
Intrauterine growth retardation predisposes toward long-term morbidity from type 2 diabetes and cardiovascular disease. To explain this association, the concept of programming was introduced to indicate a process whereby a stimulus or insult at a critical period of development has lasting or lifelong consequences on key endocrine and metabolic pathways. Subtle changes in cell composition of tissues, induced by suboptimal conditions in utero, can influence postnatal physiological functions. There is increasing evidence, suggesting that liver may represent one of the candidate organs targeted by programming, undergoing structural, functional and epigenetic changes following exposure to an unfavorable intrauterine environment. The aim of this review is to provide insights into the molecular mechanisms underlying liver programming that contribute to increase the cardiometabolic risk in subjects with intrauterine growth restriction.

PLoS One 2011; 6:e29562. [PMID: 22242132 PMCID: PMC3248435 DOI: 10.1371/journal.pone.0029562] [Citation(s) in RCA: 37] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2011] [Accepted: 11/30/2011] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND The IGF system is recognised to be important for fetal growth. We previously described increased Insulin-like growth factor binding protein (IGFBP)-2 cord serum concentrations in intra-uterine growth retardation (IUGR) compared with appropriate for gestational age (AGA) newborns, and a positive relationship of IGFBP-2 with Interleukin (IL)-6. The role of cortisol in the fetus at birth is largely unknown, and interactions among peptides are their real effect on birth size is unknown. Furthermore, almost all studies have previously assayed peptides in serum several years after birth, and follow-up data from pregnancy are always lacking. This study aimed at establishing and clarifying the effect of cord serum insulin, IGF-II, IGFBP-2, cortisol and IL-6 concentrations on birth length and weight. METHODS 23 IUGR and 37 AGA subjects were followed up from the beginning of pregnancy, and were of comparable gestational age. Insulin, IGF-II, IGFBP-2, cortisol and IL-6 concentrations were assayed in cord serum at birth, and a multiple regression model was designed and applied to assess which were the significant biochemical determinants of birth size. RESULTS Insulin, cortisol, and IL-6, showed similar concentrations in IUGR and AGA as previously described, whereas IGF-II was lower, and IGFBP-2 increased in IUGR compared with AGA. IGF-II serum concentration was found to have a significant positive effect on both birth length (r:(:)0.546; p: 0.001) and weight (r:0.679; p: 0.0001). IGFBP-2 had a near significant negative effect on both birth weight (r:-0.342; p: 0.05) and length (r:-0.372; p:0.03). CONCLUSION IGF-II cord serum concentration was shown to have a significant positive effect on both birth length and weight, whereas IGFBP-2 had a significant negative effect. Insulin, cortisol, and IL-6 cord serum concentrations had no significant effect on birth size.

Abstract
Small for GA (SGA) children are at risk for developing the metabolic syndrome. Those who do not catch up, and remain short (SSGA), may benefit from GH therapy. 11β Hydroxysteroid dehydrogenase type 1 (11β-HSD-1) is expressed in visceral fat and is implicated in metabolic morbidity. We hypothesized that SSGA children will have increased basal and glucocorticoid (GC)-stimulated 11β-HSD-1 activity. Twenty SSGA children, aged 7.1 ± 1 y (mean ± SD), were studied before and while on GH therapy and compared with 12 normal age-matched controls. 11β-HSD-1 activity was evaluated by gas chromatography mass spectrometry (GCMS) of urinary steroid product/substrate ratios. GC-stimulated 11β-HSD-1 activity was assessed after overnight dexamethazone (DEX), by oral cortisone conversion to cortisol. In SSGA children, 11β-HSD-1 activity was lower (p < 0.05) and GC-stimulated activity enhanced. SSGA children had maximal cortisol generation of 883 ± 108 compared with 690 ± 63 nmol/L in controls (p < 0.04). GH treatment suppressed 11β-HSD-1 activity. GC-stimulated enzyme activity correlated negatively with GA (r = -0.53, p < 0.01) and birth weight (r = -0.55, p < 0.01). SSGA is associated with enhanced GC-stimulated 11β-HSD-1 activity. This may be programmed in utero, as it is not a function of body composition or secondary metabolic derangement. GH therapy normalizes GC-stimulated 11β-HSD-1 activity.

Abstract
Chronic undernutrition causes reduced growth and endocrine adaptations in order to maintain basic life processes. In the present study, the biochemical profiles of chronically undernourished children were determined in order to test the hypothesis that chronic undernutrition also causes changes in lipid profile in pre-school children. The study population comprised 80 children aged between 12 and 71 months, including 60 with moderate undernutrition [height-for-age Z (HAZ) scores ≤ -2 and > -3] and 20 with severe undernutrition (HAZ scores ≤ -3). Socioeconomic, demographic and environmental data were obtained by application of a questionnaire, and anthropometric measurements and information relating to sex, age and feeding habits were collected by a trained nutritionist. Blood samples were analysed for haemoglobin, vitamin A, insulin-like growth factor 1 (IGF-1) and serum lipids, while cortisol was assayed in the saliva. Faecal samples were submitted to parasitological investigation. Analysis of variance and χ² methods were employed in order to select the variables that participated in the multivariate logistic regression analysis. The study population was socioeconomically homogeneous, while the lack of a treated water supply was clearly associated with the degree of malnutrition. Most children were parasitised and anaemia was significantly more prevalent among the severely undernourished. Levels of IGF-1 decreased significantly with increasing severity of undernutrition. Lipid analysis revealed that almost all of the children had dyslipidemia, while low levels of high-density lipoprotein were associated with the degree of undernutrition. It is concluded that chronic malnutrition causes endocrine changes that give rise to alterations in the metabolic profile of pre-school children.

Abstract
Infants with a very low birth weight are at risk of a reduced number of nephrons predisposing to kidney disorder, hypertension, and metabolic syndrome. Approximately 3% of infants are born small for gestational age (SGA), defined as birth weight and/or length at least 2 SD below the mean for gestational age (GA), independently of whether these children are born prematurely or at term. About 10% of these children do not show postnatal catch-up growth and remain of short stature during childhood. Most of these infants are not growth hormone (GH)-deficient, but may have GH resistance. Although GH-resistant, the majority of patients benefit from GH therapy, normalize height during childhood, maintain a normal growth velocity during puberty, and attain a normal adult height. To date, GH has been shown to be safe and no significant adverse effects have been demonstrated. Children with congenital chronic kidney disease (CKD) are born with subnormal birth weight and length and about 25% are born SGA. Shortness and need for GH treatment is highly correlated with weight at birth and gestational age. Primary renal disorders modify the response to GH treatment. Analysis of whether SGA is an additional risk factor for CKD regarding the development of hypertension, metabolic syndrome and cardiovascular complications is required.

Abstract
OBJECTIVE Low birth weight is a risk factor for coronary heart disease. Persons who have coronary events as adults tend to have been small at birth and thin at 2 yr of age, after which they tended to increase their body mass index (BMI). Our aim was to determine whether BMI gain is associated to alterations in insulin sensitivity and/or lipid profile in children born small for gestational age (SGA). DESIGN Retrospective case-control study. METHODS We studied 78 children (mean age 7.8+/-2.5 yr): 26 SGA children with catch-up growth in BMI (CGB-SGA) (BMI= 10th to 75th centile), 26 SGA without catch-up growth (NCGB-SGA) (BMI<10th centile), and 26 appropriate for gestational age (AGA) control children (BMI: 10th to 75th centile). For each CGB-SGA child, we selected an NCGB-SGA and an AGA child of the same gender, age (within 1 yr), and pubertal status. SGA children were also subdivided into 2 groups according to post-natal catch-up growth in height (CGH). RESULTS Glucose was significantly lower in NCGBSGA than AGA group (p=0.02). No significant differences in fasting insulin, fasting glucose/insulin ratio, homeostasis model assessment, quantitative insulin-sensitivity check index, and lipid profile were found among the 3 groups. HDL-cholesterol proved significantly reduced in SGA children with post-natal CGH (p=0.02). CONCLUSIONS Our findings do not support the hypothesis of early alterations in insulin sensitivity and lipid metabolism in CGB-SGA subjects during childhood provided that BMI remains within the normal range. Finally, the finding of reduced HDL-cholesterol levels in CGH-SGA children suggests detrimental metabolic effects of the height gain.

Abstract
The first trimester of pregnancy is the time during which organogenesis takes place and tissue patterns and organ systems are established. In the second trimester the fetus undergoes major cellular adaptation and an increase in body size, and in the third trimester organ systems mature ready for extrauterine life. In addition, during that very last period of intrauterine life there is a significant increase in body weight. In contrast to the postnatal endocrine control of growth, where the principal hormones directly influencing growth are growth hormone (GH) and the insulin-like growth factors (IGFs) via the GH-IGF axis, fetal growth throughout gestation is constrained by maternal factors and placental function and is coordinated by growth factors. In general, growth disorders only become apparent postnatally, but they may well be related to fetal life. Thus, fetal growth always needs to be considered in the overall picture of human growth as well as in its metabolic development.

Abstract
Animal studies reveal that early deprivation impairs regulation of the hypothalamic-pituitary-adrenocortical (HPA) axis, potentially increasing vulnerability to stressors throughout life. To examine early deprivation effects on basal HPA axis activity in humans, basal cortisol levels were examined in 164 internationally adopted children who had experienced varying degrees of preadoption deprivation. Duration of institutional care, age at adoption, and parent ratings of preadoption neglect indexed a latent factor of Deprived Care. Adoption measures of height and weight standardized to World Health Organisation norms indexed a latent factor of Growth Delay that was viewed as another reflection of deprivation. Cortisol samples were collected 3.3-11.6 years postadoption (Md = 7.3 years) at home on 3 days approximately 30 min after wakeup and before bedtime. Both early a.m. levels and the decrease in cortisol across the day were examined. A structural equation model revealed that preadoption Deprived Care predicted Growth Delay at adoption and Growth Delay predicted higher morning cortisol levels and a larger diurnal cortisol decrease.

Abstract
OBJECTIVE Low birthweight is a risk factor for metabolic and cardiovascular disorders in later adult life. Changes in the activity of 11beta-hydroxysteroid dehydrogenase type 2 (11beta-HSD2) and the consequent disequilibrium between cortisol (F) and cortisone (E) are thought to be a key mechanism for these effects. We investigated whether prenatal programming leads to alterations in F/E ratios on a systemic level. DESIGN, PATIENTS AND METHODS In a cross-sectional, retrospective study we analysed sera of 132 children born small for gestational age (SGA) (aged 2-13 years) with persistent short stature [< -2 standard deviation score (SDS)] and of 25 children born appropriate for gestational age (AGA) (aged 4-11 years) with normal body height. Thirty-one per cent of the SGA and 44% of the AGA children were born preterm. Serum E and F concentrations were measured using tandem mass spectrometry. To exclude species-specific effects, we studied the 11beta-HSD system by measuring the ratio of corticosterone (B) to dehydrocorticosterone (11OH-B) in rats that were born SGA after protein restriction of the female dams during pregnancy. RESULTS F, E and the F/E ratio in serum did not differ in these children when comparing SGA to children who were born AGA and had normal height. The concentrations were independent of weight and length SDS at birth as well as gestational age. In rats born SGA, the B/11OH-B ratio was not different to that in normal control animals at 6, 11 and 15 weeks of life. CONCLUSION We found no alterations in systemic cortisol-cortisone conversion either in short children born SGA or in SGA rats. However, local modifications of the 11beta-HSD system may be possible.

Abstract
AIM To establish the difference in plasma cortisol concentrations between newborns with intrauterine growth-restricted (IUGR) and appropriate for gestational age (AGA) birthweights. SUBJECTS AND METHODS We measured plasma cortisol concentrations in the umbilical venous cord blood of 68 IUGR newborns and 71 AGA birthweight newborns. All newborns were delivered in term, vaginally, in the morning, within 8 hours and had APGAR scores greater or equal to eight. RESULTS There was no significant difference between compared groups according to maternal age, parity, gestational age and neonatal gender. Neonatal plasma cortisol levels were significantly lower in the IUGR (median: 312.3 mmol/L, min-max: 158.9-588.1 mmol/L) compared to the AGA group (median: 458.7 mmol/L, min-max: 314.5-718.5 mmol/L) (Mann-Whitney U-test; P<0000). The probability of having a cortisol plasma level greater than or equal to 458.7 mmol/L for IUGR newborns was only 1:12, and to have cortisol plasma level less than or equal to 312.3 mmol/L for AGA newborns was much lower (0:34). In the range of plasma cortisol level between 312.3 mmol/L and 458.7 mmol/L, no statistically significant difference in the plasma cortisol level between IUGR and AGA newborns was found. CONCLUSIONS Neonatal plasma cortisol level is lower in the IUGR compared to the AGA group. Our results suggest that endocrine relationships seem to be lost in a specific group of the IUGR newborns. Although we usually tend to simplify the problem and declare only one cause, this time it is impossible. It is probable that the cause is hidden in small and insufficient placenta with deranged auto-regulation of placental 11beta-HSD-2 mechanism.

Abstract
One hundred twenty-three children with intrauterine growth retardation were prospectively followed from birth to 9 to 10 years of age in order to characterize their specific neurodevelopmental and cognitive difficulties and to identify clinical predictors of such difficulties. Perinatal biometric data and risk factors were collected. Outcome was evaluated at age 9 to 10 by neurodevelopmental, cognitive, and school achievement assessments. Sixty-three children served as controls who were appropriate for gestational age. Significant differences in growth (P < .001), neurodevelopmental scores (P < .001), intelligence quotient (IQ) (P < .0001), and school achievements measured by the Kaufmann Assessment Battery for Children (P < .001) were found between the children with intrauterine growth retardation and controls. Children with intrauterine growth retardation demonstrated a specific profile of neurocognitive difficulties at school age, accounting for lower school achievements. The best perinatal parameter predictive of neurodevelopment and IQ was the Cephalization Index (P < .001). Somatic catch-up growth at age 2 and at age 9 to 10 correlated with favorable outcome at 9 to 10 years of age.

Abstract
Depending on the definitions used, up to 10% of all live-born neonates are small for gestational age (SGA). Although the vast majority of these children show catch-up growth by 2 yr of age, one in 10 does not. It is increasingly recognized that those who are born SGA are at risk of developing metabolic disease later in life. Reduced fetal growth has been shown to be associated with an increased risk of insulin resistance, obesity, cardiovascular disease, and type 2 diabetes mellitus. The majority of pathology is seen in adults who show spontaneous catch-up growth as children. There is evidence to suggest that some of the metabolic consequences of intrauterine growth retardation in children born SGA can be mitigated by ensuring early appropriate catch-up growth, while avoiding excessive weight gain. Implicitly, this argument questions current infant formula feeding practices. The risk is less clear for individuals who do not show catch-up growth and who are treated with GH for short stature. Recent data, however, suggest that long-term treatment with GH does not increase the risk of type 2 diabetes mellitus and the metabolic syndrome in young adults born SGA.

Abstract
Intrauterine growth restriction (IUGR) is associated with accelerated growth and increased adiposity in early life due to unknown mechanisms, which could include increased thyroid hormone (TH) action. We hypothesized that placental restriction (PR) of fetal growth would increase circulating TH concentrations and alter their response to fasting, and that these would relate to growth and body composition in the young lamb. PR reduced size at birth, increased fractional growth rates (FGRs) of soft and skeletal tissues up to 30 days of age, and slowed the ontogenic decrease in plasma total T3 and plasma total T3/T4. PR did not alter the abundance of plasma THs after short-term fasting. In general, plasma total T3 and total T3/T4 ratio correlated negatively, whereas plasma total T4 correlated positively with size at birth. Absolute growth rates of weight and crown-rump length correlated positively with plasma total T3 and total T4 between days 15 and 35. Current FGRs for weight and metatarsal length correlated positively with plasma total T3 between days 20 and 35. In conclusion, PR and small size at birth reduce plasma total T4 and increase plasma total T3 postnatally, whereas catch-up growth relates to increased abundance of the more bioactive forms of TH. Finally, greater soft tissue growth occurs in PR compared with control lambs at the same circulating TH concentrations. This suggests that PR and small size at birth may increase activation of T4 to T3 and sensitivity of soft tissues to TH, which may contribute to catch-up growth following IUGR.

Abstract
OBJECTIVES To analyse IGFs in respect to somatic growth and neonatal diseases during the first 6 months of life. METHODS IGF-I, IGF-II and IGF binding proteins (IGFBP-1, -2, -3) were determined by immunoassays in neonatal patients after birth (n = 67) and at 3 (3 mo; n = 75) and 6 months (6 mo; n = 47) of corrected postnatal age. Data on growth were tested for associations to the gestational age, birth weight (bw) SDS (/-2 SDS), neonatal morbidity and therapeutic strategies. RESULTS All IGFs and IGFBPs changed significantly between birth and 3 mo of corrected age (p < 0.05). Perinatal respiratory diseases influenced IGF-II at 3 mo, and bronchopulmonary dysplasia IGF-II at 3 and 6 mo (all p < 0.05). IGF-I differed between the subgroups bw /-2 SDS (p < 0.05). At 3 mo, IGFBP-1 was significantly increased in infants with glucocorticoid administration during the first four weeks of life. CONCLUSION The first months of life are characterised by a pole reversal of the somatotropic axis: IGFBP-1 and -2 decrease and IGFBP-3 increases. Respiratory diseases with an origin in the neonatal period, glucocorticoid therapy and low birth weight have an impact on the IGF pattern up to 6 mo. Prospective studies are necessary to investigate, whether the described link between the IGF/IGFBP axis and respiratory morbidity in neonatal patients has an impact on development in later infancy.

Abstract
Children born small for gestational age (SGA) are at high risk of permanent short stature, with approximately 10% continuing to have stature below the third centile throughout childhood and adolescence and into adulthood. The mechanisms involved in catch-up growth, and those that prevent catch-up growth, are still unknown. To date, no reliable anthropometric or endocrine parameter predictive of postnatal catch-up growth has been identified. However, subtle abnormalities in the growth hormone-insulin-like growth factor axis, the hypothalamic-pituitary-adrenal axis and thyroid function have been described, and a mechanism involving intrauterine programming of hypothalamic-pituitary function has been proposed.

Abstract
IGF binding protein-1 (IGFBP-1) inhibits the mitogenic actions of the IGFs. Circulating IGFBP-1 is elevated in newborns and experimental animals with fetal growth restriction (FGR). To establish a causal relationship between high circulating IGFBP-1 and FGR, we have generated transgenic mice using the mouse alpha-fetoprotein gene promoter to target overexpression of human IGFBP-1 (hIGFBP-1) in the fetal liver. These transgenic mice (AFP-BP1) expressed hIGFBP-1 mainly in the fetal hepatocytes, starting at embryonic d 14.5 (E14.5), with lower levels in the gut. The expression peaked at 1 wk postnatally (plasma concentration, 474 +/- 34 ng/ml). At birth, AFP-BP1 pups were 18% smaller [weighed 1.34 +/- 0.02 g compared with 1.62 +/- 0.04 g for wild type (WT); P < 0.05], and they did not demonstrate any postnatal catch-up growth. The placentas of the AFP-BP1 mice were larger than WT from E16.5 onwards (150 +/- 12 for AFP-BP1 vs. 100 +/- 5 mg for WT at E16.5; P < 0.05). Thus, this model of FGR is associated with a larger placenta, but without postnatal catch-up growth. Overall, these data clearly demonstrate that high concentrations of circulating IGFBP-1 are sufficient to cause FGR.

Abstract
OBJECTIVE To explore the independent associations of body height, body mass index (BMI), waist circumference and hip circumference with high-density lipoprotein-cholesterol (HDL-cholesterol) and non-high-density lipoprotein-cholesterol (non-HDL-cholesterol), in a large general population sample. DESIGN Cross sectional. SETTING Urban and rural areas throughout Greece. SUBJECTS In total,10 837 volunteers, 2034 men and 8803 women, aged 25-82 years, participants in the European Prospective Investigation into Cancer and Nutrition study (EPIC), who have never smoked and never been treated for dyslipidemia. INTERVENTIONS None. RESULTS The effect of height on non-HDL-cholesterol was opposite but in absolute terms almost as important as that of BMI with no gender interaction. Among women, hip circumference was inversely associated with non-HDL-cholesterol (standardized coefficient bst = -1.11, with standard error (s.e.)=0.42) and positively with HDL-cholesterol (bst = 0.85, s.e.= 0.12) whereas, waist circumference was inversely associated with HDL-cholesterol (bst = -1.16, s.e.=0.13) and strongly positively with non-HDL-cholesterol (bst = 8.83, s.e.= 0.45). Among men, associations were generally weaker (in absolute terms by about 50%) and for hip circumference the association with non-HDL-cholesterol was actually non significantly positive. CONCLUSIONS Height was inversely associated with HDL and non-HDL-cholesterol implicating early life phenomena in the regulation of these variables. Larger hip circumference among women had beneficial effects on blood cholesterol fractions by increasing HDL-cholesterol and reducing non-HDL-cholesterol, whereas among men the relevant effects were less clear cut. The detrimental consequences of large waist circumference on both HDL (reduction) and non-HDL-cholesterol (increase) were also particularly marked among women. SPONSORSHIP The European Prospective Investigation into Cancer and Nutrition (EPIC) is coordinated by the International Agency for Research on Cancer (World Health Organization) and supported by the Europe Against Cancer Program of the European Commission. The Greek segment of the EPIC study is also supported by the Greek Ministry of Health and the Greek Ministry of Education. This study was additionally supported by the fellowship 'Vassilios and Nafsika Tricha'.

Abstract
Children born small for gestational age are at high risk of developing insulin resistance, type 2 diabetes, hyperlipidemia, hypertension and cardiovascular disease in adulthood. In addition, approximately 10% of SGA children do not achieve a normal adult height. Studies performed in SGA children to evaluate markers of metabolic disease in prepubertal, pubertal and adolescent subjects, indicate a higher prevalence of subtle endocrine and metabolic abnormalities that may precede the onset of overt disease in adulthood. At present, however, there are no conclusive data supporting the need of systematic close monitoring of GH-IGF, hypothalamus-pituitary-adrenal and hypothalamus-pituitary-gonadal axes, as well as insulin sensitivity, glucose homeostasis, and lipid metabolism. Monitoring of metabolic parameters should probably be reserved to SGA children with genetic predisposition to type 2 diabetes and hyperlipidemia, as early identification of metabolic alterations might prompt effective preventive interventions and, ultimately, reduce cardiovascular risk.

Abstract
Intrauterine growth retardation (IUGR) increases the risk of neuroendocrine reprogramming. In the rat, IUGR leads to persistent changes in cerebral mRNA levels. This suggests lasting alterations in IUGR cerebral transcriptional regulation, which may result from changes in chromatin structure. Candidate nutritional triggers for these changes include altered cerebral zinc and one-carbon metabolite levels. We hypothesized that IUGR affects cerebral chromatin structure in neonatal and postnatal rat brains. Rats were rendered IUGR by bilateral uterine artery ligation; controls (Con) underwent sham surgery. At day of life 0 (d0), we measured cerebral DNA methylation, histone acetylation, expression of chromatin-affecting enzymes, and cerebral levels of one-carbon metabolites and zinc. At day of life 21 (d21), we measured cerebral DNA methylation and histone acetylation, as well as the caloric content of Con and IUGR rat breast milk. At d0, IUGR significantly decreased genome-wide and CpG island methylation, as well as increased histone 3 lysine 9 (H3/K9) and histone 3 lysine 14 (H3/K14) acetylation in the hippocampus and periventricular white matter, respectively. IUGR also decreased expression of the chromatin-affecting enzymes DNA methyltransferase 1 (DNMT1), methyl-CpG binding protein 2 (MeCP2), and histone deacetylase (HDAC)1 in association with increased cerebral levels of zinc. In d21 female IUGR rats, cerebral CpG DNA methylation remained lower, whereas H3/K9 and H3/K14 hyperacetylation persisted in hippocampus and white matter, respectively. In d21 male rats, IUGR decreased acetylation of H3/K9 and H3/K14 in these respective regions compared with controls. Despite these differences, caloric, fat, and protein content were similar in breast milk from Con and IUGR dams. We conclude that IUGR results in postnatal changes in cerebral chromatin structure and that these changes are sex specific.

Abstract
Intrauterine growth restriction (IUGR) may influence adrenocortical function, lipid metabolism and glucose tolerance in later life. Both cortisol (F) synthesis and metabolism contribute to serum F concentrations. 11beta-hydroxysteroid dehydrogenase type 2 (11beta-HSD2) enzyme converts F to biologically inactive cortisone (E). Decreased 11beta-HSD2 activity has been suggested for a reason to IUGR and to its metabolic consequences. Our aim was to develop a specific liquid chromatography - tandem mass spectrometry (LC-MS/MS) method for analysing serum F and E concentrations, to determine the F/E ratios, and to correlate them with serum lipid concentrations, insulin resistance index (HOMA-IR), and catch-up growth in children born small for gestational age (SGA). The mean serum F and E concentrations, and F/E ratios did not differ between the SGA and their control children at 12 y age. The SGA children in the highest F/E ratio quartile had poorer gain in height between 0-12 y, and higher serum total and LDL cholesterol levels than those with lower F/E ratios. In logistic regression analysis, high LDL cholesterol, high HOMA-IR, and early pubertal stage associated with high F/E ratio in the SGA children. In conclusion, our LC-MS/MS method enables a reliable measurement of both F and E concentrations from a single serum sample. High serum F/E ratio may be associated with IUGR, its metabolic consequences, and poor catch-up growth in a subset of SGA children.

Abstract
BACKGROUND Intrauterine growth retardation (IUGR) is a major cause of short stature in childhood. Most but not all children experience catch-up growth by 2 years of age. METHODS We investigated the endocrine profile (thyroid function, prolactin, cortisol, C-peptide and insulin-like growth factor-I [IGF-IJ levels) of 57 children with IUGR, aged 2-10 years, and compared it with 30 controls whose birth weight was appropriate-for-gestational-age. RESULTS The hormonal profile for both groups was similar for thyroid hormones, prolactin, C-peptide and IGF-I. Cortisol levels were significantly lower in the IUGR group compared to controls (p <0,05). When the IUGR group was divided into 'catch-up' growth and 'non-catch-up' subgroups, the latter had significantly lower IGF-I levels (p <0.001). CONCLUSIONS Lower cortisol levels in children born with IUGR may reflect impaired function of the hypothalamic-pituitary-adrenal axis associated with this condition. The significantly lower IGF-I levels of the 'non-catch-up' subgroup may be involved in their failure to grow.

Abstract
AIM To determine the concentration of insulin-like growth factor-I (IGF-I) in exclusively breast-fed (BF) and formula-fed (FF) infants in the first 5 months of life and to study the relationship between the IGF-I level and Z score for weight, body mass index (BMI) and tricipital skin-fold thickness. METHODS We performed a cross-sectional study in order to evaluate serum IGF-I in 97 age-matched healthy term infants: 50 FF and 47 BF. RESULTS FF infants showed higher values of IGF-I (38.9 +/- 12 ng/ml) when compared to BF infants (26.7 +/- 11.6 ng/ml; p < 0.05). A positive correlation was found between IGF-I values and Z score for weight (p < 0.001), BMI (p = 0.014), tricipital skin-fold thickness (p = 0.043) and age (p = 0.02). CONCLUSION These results show that the IGF-I serum concentration is higher in FF infants. The observed association between IGF-I and Z score for weight, BMI, tricipital skin-fold thickness confirms the effect of different infant feeding on body size.

Abstract
OBJECTIVE To analyze spontaneous nocturnal GH profiles, IGF1 and IGFBP3 serum levels, as well as IGF1:IGFBP3 molar ratios in SGA children without postnatal catch-up growth. METHODS Short statured prepubertal SGA children (n = 24) were matched retrospectively for sex, age and BMI to short statured children born appropriate for gestational age (AGA), who underwent the same diagnostic program. GH deficiency was excluded in all children by a normal increase of GH in 2 stimulation tests (>8 microg/L). For assessment of spontaneous nocturnal GH secretion, GH serum levels were measured every 20 min for 10 h. Pulsatility was analyzed with Pulsar. RESULTS None of the Pulsar derived descriptive parameters showed a significant difference between SGA and AGA children. Overall, median IGF1 levels were approximately one SDS below zero SDS (p < 0.001), whereas IGFBP3 levels were normal in both groups. Thus, the IGF1:IGFBP3 molar ratios were significantly lower from zero (p < 0.01) in SGA as well as in AGA children. However, IGF1- and IGFBP3-SDS levels related either to chronological or to bone age did not differ significantly between SGA and AGA children. CONCLUSIONS Building matched pairs of short statured children born either SGA or AGA for sex, age and BMI we did not find any significant differences in spontaneous nocturnal GH secretion, IGF1, IGFBP3, and IGF1:IGFBP3 molar ratios.
