Abstract
PURPOSE Vitamins and trace elements are essential nutrients for growth and intestinal adaptation in children with short bowel syndrome (SBS). This study aimed to assess micronutrients' status during and after weaning off PN in pediatric SBS. METHODS This retrospective study evaluated the follow-up of 31 children with SBS between Jan 2010 and Sep 2019. Clinical data were reviewed from the patients' electric medical record. Serum electrolytes, trace elements, vitamin B12, vitamin D, and folate concentrations were collected before and after enteral autonomy. RESULTS Thirty-one SBS cases were reviewed (median onset age 11 days after birth, 51.6% boys, mean PN duration 4 months, and mean residual small intestine length 58.2 cm). Median duration of follow-up was 10 months (interquartile range [IQR]: 4, 19). The common micronutrient deficiencies were zinc (51.6%), copper (38.7%), vitamin D (32.3%), and phosphorus (25.8%) after the transition to EN. The proportion of patients deficient in vitamin D decreased dramatically from 93.5% to 32.3% (P < 0.001), and serum concentrations of vitamin D increased significantly (27.4 ± 12.3 vs. 60.3 ± 32.9 nmol/l, P = 0.03) after achieving full enteral feeding more than 1 month. Additionally, serum magnesium levels significantly increased (0.76 ± 0.17 vs. 0.88 ± 0.14 mmol/l, P = 0.03). Hemoglobin levels elevated significantly after weaning off PN (104.3 ± 10.7 vs. 117.8 ± 13.7 g/l, P = 0.03). CONCLUSIONS Micronutrient deficiencies remain a common problem in pediatric SBS through intestinal rehabilitation. Therefore, we strongly recommend supplementation of more vitamin D and trace elements (zinc, copper, and phosphorus) under regular monitoring during long-term intestinal rehabilitation.

Abstract
The ultimate goal of treatment of short bowel syndrome/intestinal failure patients is to achieve enteral autonomy by eliminating parenteral nutrition (PN)/intravenous fluids (IV). After optimization of diet, oral hydration and anti-diarrheal medications, attempt should be made to eliminate PN/IV. Weaning from PN/IV should be individualized for each patient. Although teduglutide is the preferred agent for PN/IV volume reduction or successful weaning, optimal patient selection and long-term safety need further evaluation. Following PN/IV elimination, patients need long-term monitoring for nutritional deficiencies. This article will address clinical considerations before, during, and after PN/IV weaning to facilitate safe and successful PN/IV weaning process.

Abstract
Extensive resection of the intestinal tract with resulting malabsorption is known as short bowel syndrome (SBS). Adaptation and rehabilitation of the remaining small bowel occurs spontaneously after resection and can be enhanced by diet, medications, and use of intestinal trophic factors such as recombinant human growth hormone (r-hGH). Many trials have been published on the influence of r-hGH therapy in SBS patients, with varying results. Analysis of the trials has produced a set of criteria that can be used to define the patient most likely to benefit from r-hGH therapy.

Abstract
Background Several GI peptides linked to intestinal barrier function could be involved in the modification of intestinal permeability and the onset of diarrhea during adjuvant chemotherapy. The aim of the study was to evaluate the circulating levels of zonulin, glucagon-like peptide-2 (GLP-2), epidermal growth factor (EGF) and ghrelin and their relationship with intestinal permeability and chemotherapy induced diarrhea (CTD). Methods Sixty breast cancer patients undergoing an FEC60 regimen were enrolled, 37 patients completed the study. CTD(+) patients were discriminated by appropriate questionnaire and criteria. During chemotherapy, intestinal permeability was assessed by lactulose/mannitol urinary test on day 0 and day 14. Zonulin, GLP-2, EGF and ghrelin circulating levels were evaluated by ELISA tests at five time-points (days 0, 3, 10, 14, and 21). Results During FEC60 administration, the lactulose/mannitol ratio was significantly higher on day 14 than at baseline. Zonulin levels were not affected by chemotherapy, whereas GLP-2 and EGF levels decreased significantly. GLP-2 levels on day 14 were significantly lower than those on day 0 and day 3, while EGF values were significantly lower on day 10 than at the baseline. In contrast, the total concentrations of ghrelin increased significantly at day 3 compared to days 0 and 21, respectively. Ten patients (27%) suffered from diarrhea. On day 14 of chemotherapy, a significant increase of the La/Ma ratio occurred in CTD(+) patients compared to CTD(−) patients. With regards to circulating gut peptides, the AUCg of GLP-2 and ghrelin were significantly lower and higher in CTD(+) patients than CTD(−) ones, respectively. Finally in CTD(+) patients a significant and inverse correlation between GLP-2 and La/Ma ratio was found on day 14. Conclusions Breast cancer patients undergoing FEC60 showed alterations in the intestinal permeability, which was associated with modifications in the levels of GLP-2, ghrelin and EGF. In CTD(+) patients, a different GI peptide profile and increased intestinal permeability was found in comparison to CTD(−) patients. This evidence deserves further studies for investigating the potentially different intestinal luminal and microbiota conditions. Trial registration Clinical trial NCT01382667

Abstract
Early weaning induces villous atrophy in the small intestine (SI) of piglets. Oral administration of live lactic acid bacteria (LAB) can improve villous shortening. In this study, we evaluated the oral administration of a heat-killed and dried cell preparation of Enterococcus faecalis (a LAB) strain EC-12 against villous atrophy in early-weaned mice (Experiment 1) and pigs (Experiments 2 and 3). Twelve 16-days-old mice were divided into two groups in Experiment 1: gavage of EC-12 (10 mg/kg body weight (BW)/day), or control. On day 21, SI was collected. Eighteen 21-day-old pigs were divided into two groups in Experiment 2: gavage of EC-12 (10 mg/kg BW/day), or control. After 10 days, the villous height of jejunum was measured. Six 21-day-old pigs were divided into two groups in Experiment 3: the basal diet supplemented with EC-12 at 0.05%-fed group, or the basal diet-fed group. After 10 days, the villous height of jejunum was measured. The villous heights in SI were significantly higher by EC-12 administration in all experiments. EC-12 successfully improved the villous atrophy in the early-weaned mice and pigs when EC-12 was administered orally.

Abstract
Lactic acid bacteria, either alive or dead, can improve villous atrophy caused by weaning in both piglets and mice. In this experiment, we tried to detect the molecules involved in this phenomenon with a real-time RT-PCR array approach. Weaning pups of mice were administered either a suspension of an Enterococcus faecalis EC-12 dried cell preparation (EC-12) or saline for 11 consecutive days after weaning. The jejunal and ileal villous heights were measured histologically, and the expression levels of 86 genes were analyzed for the jejunal and ileal epithelial cells and the lamina propria (LP). EC-12 induced significantly higher villous height in the jejunum and the ileum. Interleukin (IL)-6, fibroblast growth factor (FGF)-7, -10, and -22, and the platelet-derived growth factor (PDGF) beta in the jejunal and the ileal LP were the most enhanced genes by EC-12. The possible role of these molecules in the improvement of villous atrophy is discussed.

Abstract
Ghrelin is the natural endogenous ligand for growth hormone secretagogue receptors. This peptide regulates energy homeostasis and expenditure and is a potential link between gut absorptive function and growth. We hypothesized that ghrelin may induce a proliferative and antiapoptotic action promoting the recovery of the hypotrophic gut mucosa. Therefore, the aim of the study was to determine the action of exogenous ghrelin following gut mucosal hypotrophia in rats fed an elemental diet. An elemental diet provides readily absorbable simple nutrients and is usually given to patients with absorptive dysfunction. Male Wistar rats ( n = 48) were fed the elemental diet for one week to induce mucosal hypotrophy and then treated for another week with systemic ghrelin and pair-fed with either a normoproteic or hyperproteic isocaloric liquid diet. Another group received a standard diet instead of the elemental diet and served as control (normotrophy). The elemental diet induced intestinal hypotrophia characterized by decreased proliferation in the ileum and increased apoptosis in jejunum and ileum. Ghrelin administration restored normal levels of proliferation in the ileum and apoptosis in the jejunum, with partial apoptosis restoration in the ileum. Ghrelin levels in plasma and fundus were increased in all groups, although the highest levels were found in rats treated with exogenous ghrelin. Ghrelin administration has a positive effect in the hypotrophic gut, regulating both proliferation and apoptosis towards a physiological balance counteracting the negative changes induced by an elemental diet in the intestines.

Abstract
Some amino acids exert a wide range of regulatory effects on gene expression via the activation of different signalling pathways and transcription factors, and a number of cis elements were shown to respond to changes in amino acid concentration. Particular attention has been paid to the effects of glutamine and arginine, which modulate a number of cell functions through the activation of various pathways in different tissues. In the intestine, appropriate concentrations of both arginine and/or glutamine contribute to facilitate cell proliferation, to limit the inflammatory response and apoptosis, and to modulate intermediary metabolism through specific transcription factors. Particularly, besides its role as a major fuel for enterocytes, the regulatory effects of glutamine have been extensively studied and the molecular mechanisms involved appear diversified and complex. Indeed, in addition to a major role of NF-kappaB in its anti-inflammatory action and a stimulatory role of AP-1 in its growth-promoting action and cell survival, the involvement of some other transcription factors, such as PPAR-gamma or HSF-1, was shown to maintain intestinal cell integrity. The signalling pathways leading to the activation of transcription factors imply several kinases, particularly MAP kinases in the effect of glutamine and p70 S6 kinase for those of arginine, but in most cases the precise pathways from the entrance of the aminoacid into the cell to the activation of gene transcription has remained elusive.

Abstract
Weaning piglets were fed an L-glutamine-supplemented diet with the aim of monitoring the effects on gut mucosal turnover and barrier function, to elucidate the potential preventive or therapeutic roles of glutamine as a nutraceutical or 'functional food'. Sixteen female weaning piglets were divided into two groups, which were fed a control diet (Ctr group: n = 8) or a Ctr + 0.5% L-glutamine diet (G group: n = 8) for 28 days. In the ileum of group G piglets the villus height (V) and crypt depth (C) were increased, and the V:C ratio was decreased (p < 0.01). The PCNA and TUNEL immunoreactivities were also tested. The number of mitotic mucosal cells (M) was increased, and that of mucosal cells with apoptotic nuclei (A) decreased in such a way that the A:M index diminished (p < 0.01). The A:M index also decreased at the level of some components of the gut-associated lymphatic tissue (GALT), thus indicating a positive effect on the gut barrier function. This trial showed that L: -glutamine supplementation influenced some morphofunctional characteristics of piglet ileal mucosa. These data corroborate the nutraceutical role of glutamine as a trophic agent for mucosal repair, improvement of barrier function and gut adaptation in the swine per se and as an animal model.

Abstract
Molecular data rapidly accumulating on the regulation of gene expression by amino acids in mammalian cells highlight the large variety of mechanisms that are involved. Transcription factors, such as the basic-leucine zipper factors, activating transcription factors and CCAAT/enhancer-binding protein, as well as specific regulatory sequences, such as amino acid response element and nutrient-sensing response element, have been shown to mediate the inhibitory effect of some amino acids. Moreover, amino acids exert a wide range of effects via the activation of different signalling pathways and various transcription factors, and a number of cis elements distinct from amino acid response element/nutrient-sensing response element sequences were shown to respond to changes in amino acid concentration. Particular attention has been paid to the effects of glutamine, the most abundant amino acid, which at appropriate concentrations enhances a great number of cell functions via the activation of various transcription factors. The glutamine-responsive genes and the transcription factors involved correspond tightly to the specific effects of the amino acid in the inflammatory response, cell proliferation, differentiation and survival, and metabolic functions. Indeed, in addition to the major role played by nuclear factor-kappaB in the anti-inflammatory action of glutamine, the stimulatory role of activating protein-1 and the inhibitory role of C/EBP homology binding protein in growth-promotion, and the role of c-myc in cell survival, many other transcription factors are also involved in the action of glutamine to regulate apoptosis and intermediary metabolism in different cell types and tissues. The signalling pathways leading to the activation of transcription factors suggest that several kinases are involved, particularly mitogen-activated protein kinases. In most cases, however, the precise pathways from the entrance of the amino acid into the cell to the activation of gene transcription remain elusive.

Abstract
AIM: To investigate the intestine and body development of intrauterine growth retardation (IUGR) rats under early different protein diet and to analyze the correlation between leptin and intestine and body development.
METHODS: An IUGR rat model was established by food restriction of pregnant female rats. Fifty-six neonatal IUGR rats and 24 neonatal normal rats were randomly divided into normal control group (C group), IUGR model group (SC group), low protein diet IUGR group (SL group), and high protein diet IUGR group (SH group). Eight rats were killed per group at wk 0, 4, and 12. Serum leptin, body weight (BW), body length (BL), intestinal weight (IW), intestinal length (IL), and intestinal disaccharidase (including lactase, maltase, and saccharase) were detected.
RESULTS: BW (4.50 ± 0.41 g), BL (5.96 ± 0.40 cm), IW (0.05 ± 0.01 g), and IL (15.9 ± 2.8 cm) in neonatal IUGR rats were much lower than those in C group (6.01 ± 0.55 g, 6.26 ± 0.44 cm, 0.10 ± 0.02 g, 21.8 ± 2.7 cm, P<0.05), while intestinal lactase and maltase activities were higher than those in C group. SH group showed the fastest catch up growth and their BW, BL, IW, and IL reached the C group level at wk 4. SC group showed relatively slower catch up growth than SH group, and their BW, BL, IW did not reach the C group level at wk 4. SL group did not show intestine and body catch up growth. Intestinal maltase [344 ± 33μmol/(min/g)] and saccharase activities [138 ± 32 μmol/(min/g)] in SL group were both markedly lower than those in C group [751 ± 102, 258 ± 27 mmol/(min/g), P<0.05]. There were no significant differences in lactase activities at wk 4 and disaccharidase activities at wk 12 among all groups (P>0.05). The leptin level in SL group (0.58 ± 0.12 ng/mL) was the highest in all groups, and much lower in SH group (0.21 ± 0.03 ng/mL) than that in any other IUGR groups at wk 4 (P<0.05). Leptin was negatively related to BW (r = -0.556, P = 0.001), IW (r = -0.692, P = 0.001) and IL (r = -0.738, P = 0.000) at wk 4, while no correlation was found at wk 12.
CONCLUSION: High protein diet is a reasonable early nutritional mode to IUGR rats in promoting intestine and body catch up growth.

Abstract
The objectives of this study were to evaluate intestinal cellularity and vascularity in mature ewes in response to dietary restriction and pregnancy status and to quantify the response of these variables to increased nutrient demand of fetal growth. In Exp. 1, 28 mature Dorset x crossbred white-faced ewes (61.6+/-1.8 kg initial BW) were fed a pelleted, forage-based diet. Treatments were arranged in a 2 x 3 factorial, with dietary restriction (60% restriction vs. 100% maintenance for respective states of pregnancy) and pregnancy status (nonpregnant, NP; d 90 and 130) as main effects. Dietary treatments were initiated on d 50 of gestation and remained at 60 or 100% maintenance throughout the experiment. Nonpregnant ewes were fed dietary treatments for 40 d. In Exp. 2, four Romanov ewes were naturally serviced (Romanov fetus and Romanov dam; R/R); two Romanov embryos per recipient were transferred to four Columbia recipients (Romanov fetus and Columbia recipient; R/C), and three Columbia ewes were naturally serviced (Columbia fetus and Columbia dam; C/C). In Exp. 1, dietary restriction and pregnancy status interacted with regard to maternal jejunal DNA concentration (P < 0.01), with restricted ewes having a greater DNA concentration (mg/g; fresh basis) at d 130. Vascularity (percentage of total tissue area) in the jejunum was increased (P < 0.06) as a result of dietary restriction and pregnancy status. Total microvascular volume ofjejunal tissue was not altered by dietary restriction and increased (P < 0.01) at d 130 of pregnancy. In Exp. 2, R/R ewes had less (P < 0.09) DNA (g) in the jejunum compared with R/C and C/C ewes. Jejunal vascularity (%) was increased (P < 0.05) in R/R ewes compared with R/C or C/C ewes, whereas total jejunal microvascular volume remained unchanged. These data demonstrate intestinal vascular density responds to changes in diet and physiological state. In addition, pregnancy increased total jejunal microvascular volume.

Abstract
Intestinal epithelial cell turnover (proliferation, migration, differentiation, and apoptosis) and gut barrier functions are dynamic processes that are markedly affected by nutritional status, the route of feeding, and the adequacy of specific nutrients in the diet. Emerging studies are defining potential therapeutic roles for specific nutrients and diet-derived compounds (including arginine, glutamate, glutamine, glutathione, glycine, vitamin A, zinc, and specific lipids) in gut mucosal turnover, repair, adaptation after massive bowel resection, and barrier function. The role and regulation of endogenous bowel flora in generating short-chain fatty acids from diet-derived fiber and other diet-derived compounds and the effects of these agents on gut function are increasingly being elucidated. Results of these investigations should define new nutritional methods for trophic and cytoprotective effects on the intestine in conditions such as inflammatory bowel disease, malnutrition, and short bowel syndrome.

Abstract
BACKGROUND Oral administration of zinc or bovine whey-derived growth factor extract (WGFE) is known to reduce intestinal permeability and ameliorate methotrexate (MTX)-induced mucositis, respectively. OBJECTIVE We examined the effects of zinc, WGFE, and zinc plus WGFE on gut damage in MTX-treated rats. DESIGN Rats (n = 16/group) were fed zinc (1000 mg/kg diet), WGFE (32 mg/kg diet), zinc plus WGFE, or control (10 mg Zn/kg diet) diets for 7 d and then injected subcutaneously with MTX (2.5 mg/kg) for 3 d to induce gut damage. Gut histology and intestinal permeability were assessed. RESULTS The Zn+WGFE diet was associated with both reduced gut damage on day 5 and enhanced recovery on day 7. The WGFE diet ameliorated gut damage, whereas the Zn and Zn+WGFE diets enhanced repair. Gut metallothionein and tissue zinc concentrations were significantly (P < 0.01) higher with Zn and Zn+WGFE on days 5 and 7 than without zinc supplementation. The Zn and Zn+WGFE diets significantly (P < 0.05) decreased gut permeability on days 3-4 compared with the control diet. Intestinal permeability was significantly (P < 0.05) increased on days 5-6. On days 6-7, only the WGFE diet improved gut permeability (by 80%) compared with the control diet. CONCLUSIONS Dietary administration of WGFE and a pharmacologic dose of zinc reduced intestinal damage and enhanced recovery, respectively. WGFE also improved gut permeability after MTX-induced bowel damage. In combination, zinc and WGFE hastened repair of gut damage, which may have clinical application in chemotherapy-induced mucositis.

Abstract
The trefoil factor family peptides TFF1, TFF2, and TFF3 are important for gut mucosal protection and restitution. Keratinocyte growth factor (KGF) stimulates proliferation and differentiation of epithelial cells with potent effects on goblet cells. To investigate interactions between food intake and KGF, rats were fed ad libitum (control), fasted for 72 h, or fasted for 72 h and then refed for 72 h with or without KGF (3 mg. kg(-1). day(-1)). With fasting, goblet cell number in duodenum increased, TFF3 mRNA in duodenum and jejunum decreased, and TFF3 protein did not change or increased. KGF during fasting stimulated colonic growth, normalized TFF3 mRNA in duodenum and jejunum, and broadly upregulated gut goblet cell number and TFF3 protein expression. With fasting-refeeding, KGF increased small bowel and colonic mucosal growth, goblet cell number, and TFF3 protein but had variable effects on TFF3 mRNA. KGF induced TFF2 mRNA and protein in duodenum and jejunum with both nutritional regimens. We conclude that nutrient availability modifies rat intestinal goblet cell number, TFF3 mRNA, and the gut-trophic effects of KGF in a region-specific manner. KGF enhances TFF2 expression in proximal small bowel and increases goblet cell number and TFF3 protein content throughout the intestine independent of food intake.

Abstract
The nutritional support of gastrointestinal growth and function is an important consideration in the clinical care of neonatal infants. In most health infants, the provision of either breast milk or formula seems to support normal intestinal mucosal growth, but the most significant advantages of breast milk may be for host defense or gut barrier-related functions that are involved in reducing infection. The specific effects of various milk-borne growth factors on key mucosal immune and barrier functions are likely to provide valuable new clues to the advantages of human milk. A substantial number of preterm, low-birth weight babies or those suffering from compromised intestinal function, however, often cannot tolerate oral feedings and instead receive TPN. The consequences of TPN on gastrointestinal function and how this contributes to morbidity of these infants warrants further study, with respect to both clinical and basic research questions. Although enteral nutrition seems to be a critical stimulus for intestinal function, the minimal amounts and composition of nutrients necessary to maintain specific intestinal functions remain to be established. The experimental tools exist to start defining the specific nutrient requirements for the infant gut and some of these nutrients are known (e.g., glutamate, glutamine, and threonine). Peptide growth factors and gut hormones clearly play a role in gut growth and in several ways mediate the trophic actions of enteral nutrition. Although a number of these growth factors are good candidates for therapeutic use, their clinical application in the management of gastrointestinal insufficiency and disease has been slow. The emergence of GLP-2 as a trophic peptide that seems to target the gut is a promising candidate on the horizon.

Abstract
BACKGROUND & AIMS Both recombinant human growth hormone (rhGH) and glutamine (GLN) may have beneficial anabolic actions on amino acid metabolism. The aim of this study was to evaluate the additive effects of rhGH and GLN on plasma amino acids postoperatively. METHODS 31 females undergoing laparoscopic cholecystectomy were randomized to three groups: Group I (n=10) received 13 IU/m(2) of rhGH the morning of surgery and the following three postoperative days, together with glutamine-free TPN for the first two postoperative days. Group II (n=11) received rhGH as the first group, together with glutamine-enriched (7 g GLN/m(2)/day) TPN. Group III (n=10) received glutamine-enriched TPN as the second group, but rhGH was replaced by placebo. Daily plasma amino acid concentrations and nitrogen balance were determined. RESULTS In the GH treated groups, the plasma concentrations of several amino acids were decreased on the third postoperative day, compared to preoperatively. This was not observed in Group III. The changes were more pronounced in Group II. In Group II the negative AV-differences of amino acids tended to be attenuated, while the patients in Group III had increased negative AV-differences. The cumulative nitrogen balance was significantly improved in the GH groups, compared with Group III. CONCLUSION The combined treatment of growth hormone and glutamine has additive effects on AV-balances of amino acids postoperatively, whereas nitrogen balance is not further improved when adding glutamine to rhGH treatment.

Abstract
OBJECTIVE To determine whether GH improves adaptation following massive bowel resection in the aged rat fed on a high protein-content diet. MATERIAL AND METHODS Seventy-seven male Wistar rats aged 22+/-1 months underwent 80% bowel resection or laparotomy (sham-operation). They were randomly placed into one of eight groups, treated with either growth hormone (1mg/kg/day) or saline, and fed a liquid diet containing either a high or a normal protein content. Intestinal tissue and blood samples were taken seven days after surgery and analysed to measure intestinal mucosal proliferation and mucosal height, as well as plasma levels of IGF-1 and somatostatin. RESULTS Resection of the small bowel in aged rats remarkably increased villous height and crypt proliferation. Growth hormone did not potentiate the increase in mucosal height and crypt proliferation observed after intestinal resection in aged rats fed a normal protein content diet, but did in those receiving a high-protein diet. Plasma levels of IGF-1 and somatostatin were not modified by surgery or treatment. CONCLUSION Growth hormone may increase the adaptation of intestinal mucosa in aged rats undergoing massive intestinal resection, but requires an adequate nutritional support with increased amounts of high quality protein.

Abstract
The amino acid glutamine has become one of the most intensively studied nutrients in the field of nutrition and metabolic support. A variety of studies in cell culture systems, animal models of gut mucosal atrophy, injury/repair and adaptation and a limited number of clinical trials demonstrate trophic and cytoprotective effects of glutamine in small bowel and colonic mucosal cells. Although the routine clinical use of glutamine-enriched parenteral and enteral nutrient solutions remains controversial, available data demonstrate both the safety and metabolic and clinical efficacy of glutamine treatment in selected patient groups. Basic investigations are elucidating underlying mechanisms of glutamine action in intestinal cells. These will inform preclinical and clinical investigations designed to determine glutamine efficacy in selected gastrointestinal disorders. Emerging clinical trials will further define the utility of adjunctive glutamine supplementation as a component of specialized nutrition support in gastrointestinal disease.
