Abstract
Background: Energy intake and nutritional status influences a patient’s recovery from major abdominal surgery. The aim of this study is to explore and validate the clinical feasibility of an inflection-point nutrition strategy for personalized nutrition in gastric cancer patients after surgery. Methods: We conducted a prospective cohort study from a single tertiary referral hospital. Patients diagnosed with gastric cancer who met the inclusion criteria were included in this study. We collected the demographic and clinic pathological characteristics of included patients. Patients were divided into a formular nutrition (FN) and inflection-point nutrition (IPN) group. We monitored the perioperative dynamics of the oral mucosal epithelia cell apoptosis rate. Predictive factors for inflection phenomenon were investigated in univariate and multivariate analysis. Results: A total of 53 gastric cancer patients were included. A total of 30 (56.6%) patients showed the inflection phenomenon, with 9 (34.6%) patients in the FN group and 21 (77.8%) patients in the IPN group, respectively. We found that patients with the inflection phenomenon had a shorter duration of hospital stay compared to patients without the inflection phenomenon (p = 0.04). In multivariate analysis, independent predictive factors for inflection phenomenon were age (p = 0.015), operation time ≤ 300 min (p = 0.012), and average energy intake ≥ 25 Kcal/kg/day (p = 0.038). Conclusions: Our findings for the first time revealed that the oral epithelial cell apoptosis rate can promptly reflect the patients’ perioperative nutrition needs. Meanwhile, we developing a novel and feasible nutrition therapy guided by the oral epithelial cell apoptosis rate is novel in gastric cancer patients that have undergone laparoscopic gastrectomy.

Abstract
Necrotizing enterocolitis (NEC), the first cause of short bowel syndrome (SBS) in the neonate, is a serious neonatal gastrointestinal disease with an incidence of up to 11% in preterm newborns less than 1500 g of birth weight. The rate of severe NEC requiring surgery remains high, and it is estimated between 20–50%. Newborns who develop SBS need prolonged parenteral nutrition (PN), experience nutrient deficiency, failure to thrive and are at risk of neurodevelopmental impairment. Prevention of NEC is therefore mandatory to avoid SBS and its associated morbidities. In this regard, nutritional practices seem to play a key role in early life. Individualized medical and surgical therapies, as well as intestinal rehabilitation programs, are fundamental in the achievement of enteral autonomy in infants with acquired SBS. In this descriptive review, we describe the most recent evidence on nutritional practices to prevent NEC, the available tools to early detect it, the surgical management to limit bowel resection and the best nutrition to sustain growth and intestinal function.

Abstract
BACKGROUND Glutamine, a nonessential amino acid, has received increasing attention because it becomes essential during stress and catabolic conditions. Many investigations have shown that during severe stress, the consumption of glutamine exceeds glutamine synthesis, resulting in depletion of glutamine stores. The aim of this study was to evaluate the effects of supplementing parenteral diets with a glutamine-containing dipeptide, L-alanyl-L-glutamine, on rat nutrition status. METHODS Male Wistar rats were used. Animals (n = 36) were centrally catheterized and randomly assigned to 1 of the following groups based on method of parenteral nutrition (PN): control group with oral nutrition and IV infusion of a saline solution; standard parenteral nutrition (SPN) group; or alanyl-glutamine-supplemented PN (ALA-GLN PN) group (20 g/L). Parenteral nutrition was isocaloric and isonitrogenous. Infusions were administered at a rate of 2.0 mL/h over 5 days. Nutrition status was assessed by body weight change, plasma proteins, accumulated urinary creatinine, and nitrogen balance. RESULTS Accumulated urinary creatinine increased significantly after day 4 in the ALA-GLN PN group, compared with the SPN group and the controls. Body weight change significantly differed on day 5 between the ALA-GLN PN and SPN groups. After 3 days, nitrogen balance was significantly lower and nitrogen retention higher in the ALA-GLN PN group when compared with the SPN group. Albumin and transferrin concentrations decreased significantly in the SPN group, but did not differ from the controls in the ALA-GLN PN group. CONCLUSIONS Weight, plasma proteins, urinary accumulated creatinine, and nitrogen retention showed a better evolution in the group supplemented with the glutamine dipeptide when compared with the SPN group. Our results suggest a more suitable nutrition support in animals receiving L-alanyl-L-glutamine.

Abstract
Short bowel syndrome develops when the remnant mass of functioning enterocytes following massive resections cannot support growth or maintain fluid–electrolyte balance and requires parenteral nutrition. Resection itself stimulates the intestine’s inherent ability to adapt morphologically and functionally. The capacity to change is very much related to the high turnover rate of enterocytes and is mediated by several signals; these signals are mediated in large part by enteral nutrition. Early initiation of enteral feeding, close clinical monitoring, and ongoing assessment of intestinal adaptation are key to the prevention of irreversible intestinal failure. The length of the functional small bowel remnant is the most important variable affecting outcome. The major objective of intestinal rehabilitation programs is to achieve early oral nutritional autonomy while maintaining normal growth and nutrition status and minimizing total parenteral nutrition related comorbidities such as chronic progressive liver disease. Remarkable progress has been made in terms of survivability and quality of life, especially in the context of coordinated multidisciplinary programs, but much work remains to be done.

Abstract
Children with short bowel syndrome face life-threatening complications. Therefore, there is an urgent need for a new therapy to induce effective adaptation of the remnant intestine. Adaptation occurs only during feeding. We focused on preprandial acyl ghrelin and des-acyl ghrelin, and postprandial glucagon-like peptide-2 (GLP-2), which are known to have active orexigenic and trophic actions. This study aims to clarify the secretion trends of these hormones after massive small bowel resection and to obtain basic data for developing a new treatment. Sixty-three growing male rats were used: 3 were designated as controls receiving no operation and 60 were randomized into the 80% small bowel resection (80% SBR) group and the transection and re-anastomosis group. Changes in body weight, food intake, and remnant intestine morphology were also assessed for 15 days after the operation. Acyl ghrelin and des-acyl ghrelin levels increased immediately, equivalently in both operation groups (P=0.09 and 0.70). Interestingly, in 80% SBR animals, des-acyl ghrelin peaked on day 1 and acyl ghrelin peaked on day 4 (P=0.0007 and P=0.049 vs controls). GLP-2 secretion was obvious in 80% SBR animals (P=2.25×10(-6)), which increased immediately and peaked on day 4 (P=0.009 vs. controls). Body weight and food intake in 80% SBR animals recovered to preoperative levels on day 4. Morphological adaptations were evident after day 4. Our results may suggest a management strategy to reinforce these physiological hormone secretion patterns in developing a new therapy for short bowel syndrome.

Abstract
BACKGROUND Successful small intestinal (SI) adaptation following surgical resection is essential for optimizing newborn growth and development, but the potential for adaptation is unknown. The authors developed an SI resection model in neonatal piglets supported by intravenous and enteral nutrition. METHODS Piglets (n = 33, 12-13 days old) were randomized to 80% SI resection with parenteral nutrition feeding (R-PN), 80% SI resection with PN + enteral feeding (R-EN), or sham SI transection with PN + enteral feeding (sham-EN). In resected pigs, the distal 100 cm of ileum (residual SI) and 30 cm of proximal SI were left intact. All pigs received parenteral nutrition postsurgery. Enteral nutrition piglets received continuous gastric infusion of elemental diet from day 3 (40:60 parenteral nutrition:enteral nutrition). Piglets were killed 4, 6, or 10 days postsurgery. RESULTS By 10 days, R-EN piglets had longer residual SI than R-PN and sham-EN pigs (P < .05). At days 6 and 10, R-EN piglets had greater weight per length of intact SI (P < .05) and isolated mucosa (P < .05) compared to other groups. Greater gut weight in R-EN piglets was facilitated by a greater cellular proliferation index (P < .01) by 4 days compared to other groups and greater overall ornithine decarboxylase activity vs R-PN piglets (P < .05). CONCLUSIONS This new model demonstrated profound SI adaptation, initiated early postsurgery by polyamine synthesis and crypt cell proliferation and only in response to enteral feeding. These changes translated to greater gut mass and length within days, likely improving functional capacity long term.

Abstract
BACKGROUND Short bowel syndrome (SBS) develops after massive small bowel resections. Patients with less than 12 cm of jejunoileum have a slim possibility of being weaned from parenteral nutrition (PN). PATIENTS AND METHODS In a retrospective review of records of consecutive patients with SBS, 8 patients were evaluated for treatment by adaptation and weaning from PN. These included 4 patients with class I SBS (0-10 cm of small bowel), one with class II SBS (>10-25 cm), one with class III SBS (>25-50 cm), and 2 with class IV SBS (>50-75 cm). Adaptation was assessed by measuring growth in the small bowel and the ability to be weaned from PN. RESULTS Adaptation was achieved primarily by extending the length of jejunoileum by approximately 450% over the first 2.5 years after resection and by increasing the degree of colonic fermentation and absorption of nutrients. As of July 1, 2005, all of the patients were off PN, with the exception of 2 patients with class I-A SBS: patient 3 had a remaining jejunoileum of only 2.5 cm and patient 4 had a remaining jejunoileum of 9 cm but developed eosinophilic enterocolitis. These 2 patients continued with PN on alternate months. CONCLUSIONS Bowel growth after massive small bowel resection provides an objective parameter of adaptation and a means of predicting ability to be weaned from PN. Aggressive nutritional support makes even patients with class I SBS, whose disease was previously considered hopeless, likely candidates to achieve freedom from PN.

Abstract
OBJECTIVE This preliminary study was designed to explore a new method for nutritional assessment by measuring oral mucosal cell apoptosis or proliferation. METHODS Forty-two consecutive patients with gastrointestinal malignant tumors were hospitalized on the surgical wards and studied prospectively. Patient-Generated Subjective Global Assessment was used to identify malnourished patients. Anthropometric measurements including weight, body mass index, triceps skinfold thickness, and midarm muscle circumference were recorded. The serum proteins measured were retinol-binding protein (RBP), transferrin, prealbumin (PA), and albumin. Simultaneously, the rates of oral epithelial cell apoptosis and proliferation were measured by flow cytometry. Of the 20 malnourished patients, 14 were followed up in a serial study with a 3-d nutritional support therapy. Nutritional indices and oral epithelial cell apoptosis rate were measured after 3 d of nutritional support. RESULTS Malnutrition was diagnosed in 20 of 42 patients (47.6%). Oral epithelial apoptosis and proliferation rates were significantly decreased (P < 0.01 and P < 0.05, respectively) in malnourished compared with non-malnourished patients, although there were no significant differences between their anthropometric data. Malnourished patients had lower serum levels of RBP, albumin, and PA and rates of oral epithelial cell apoptosis and proliferation. The rate of oral epithelial cell apoptosis positively correlated with serum RBP (R = 0.32, P < 0.05) and PA (R = 0.33, P < 0.05). The rate of oral epithelial cell apoptosis and serum RBP and PA increased significantly in the malnourished patients who received nutritional support for 3 days. CONCLUSIONS Measuring the rate of oral epithelial cell apoptosis may be another non-invasive technique to determine nutritional assessment and is worthy of further exploration.

Abstract
OBJECTIVE To determine outcome in dogs and cats that underwent extensive (ie, > 50%) resection of the small intestine and identify factors associated with outcome. DESIGN Retrospective case series. ANIMALS 13 dogs and 7 cats. PROCEDURE Medical records were reviewed, and follow-up information was obtained. RESULTS In all 7 cats and in 8 of the 13 dogs, extensive intestinal resection was performed because of a foreign body. Mean+/-SD estimated percentage of intestine that was removed was 68+/-14% (range, 50% to 90%). Two dogs were euthanized 3 days after surgery because of dehiscence of the surgical site and development of septic peritonitis; 1 dog died of acute respiratory distress syndrome 5 days after surgery. The remaining 10 dogs and 7 cats were discharged from the hospital, and follow-up information was available for 15 of the 17. Median survival time was 828 days, and 12 of the 15 animals for which long-term follow-up information was available had good outcomes. However, none of the factors examined, including percentage of intestine resected, were significantly associated with outcome. CONCLUSIONS AND CLINICAL RELEVANCE Most dogs and cats that underwent extensive resection of the small intestine had a good outcome. The amount of intestine resected was not associated with outcome. These data may be useful in providing prognostic information in cases of extensive small intestinal resection.

Abstract
Short-bowel syndrome is a challenging entity for the gastroenterologist, requiring integration of medical, nutritional, surgical and psychological therapies. Treatment must be based on the patient's age, remaining gastrointestinal anatomy, baseline nutritional status and underlying general health as well as the numerous complications which may arise. This chapter reviews physiological alterations that occur with short-bowel syndrome and how therapies can be tailored to most adequately meet the needs of these patients. Emphasis on early stages of therapy to enhance intestinal adaptation is focused on as management during this time has a significant impact on the long-term outcome of these patients.

Abstract
BACKGROUND Low-fat diets (LFD) are utilized frequently in patients with short bowel syndrome (SBS). The purpose of this study was to investigate the effects of LFD on intestinal adaptation, enterocyte proliferation, and enterocyte cell death in a rat model of SBS. METHODS Adult male Sprague-Dawley rats were divided into 3 experimental groups: Sham-NC rats underwent bowel transection and reanastomosis and were fed normal chow (NC), SBS-NC rats underwent 75% small bowel resection and were fed NC, and SBS-rats were fed a low-fat diet (SBS-LFD). Parameters of intestinal adaptation, enterocyte proliferation, and enterocyte apoptosis were determined on day 14 after operation. RESULTS SBS-NC rats showed a significant increase (v Sham-NC) in jejunal and ileal bowel and mucosal weight, mucosal DNA and protein, villus height, and crypt depth. A significant 67% increase in crypt cell proliferation rate and 265% increase in villus enterocyte apoptosis was seen in the ileum of SBS-NC rats compared with control animals (P <.05). SBS-LFD animals showed lower ileal mucosal weight (29%; P <.05), jejunal crypt depth (20%; P <.05), and ileal villus height (21%; P <.05). A significant decrease in villus apoptosis in jejunum (74%; P <.05) and ileum (67%; P <.05) and a decrease in cell proliferation in ileum (35%; P <.05) was seen also after exposure to LFD compared with SBS-NC. CONCLUSIONS In a rat model of SBS, early LFD appears to inhibit parameters of intestinal adaptation. A possible mechanisms for this effect may be decreased cell proliferation. Decreased enterocyte loss via apoptosis, found in this study, may reflect a reduced number of enterocyte.

Abstract
Intestinal adaptation following small bowel resection (SBR) is associated with greater rates of enterocyte apoptosis by unknown mechanism(s). Because postresection adaptation is associated with increased translocation of luminal bacteria, we sought to characterize the role for the extrinsic, death receptor pathway for the activation of enterocyte apoptosis after massive SBR. We first performed SBR or sham operations in mice, and the temporal expression of caspases 8, 9, and 3, death receptors tumor necrosis factor receptor-1 (TNFR1) and Fas and corresponding ligands (TNF and Fas ligand) was determined in the remnant intestine at various postoperative time points. Ileal TNFR1 and Fas expression were then measured after SBR in the setting of increased (waved-2 mice) or decreased (exogenous EGF administration) apoptosis. Finally, intestinal adaptation and apoptosis were recorded in the remnant ileum after SBR in TNFR1-null and Fas-null mice. The expression of death receptor family proteins and caspases demonstrated only modest changes after SBR and did not correlate with the histological appearance of apoptosis. In the setting of accelerated apoptosis, TNFR1 and Fas expression were paradoxically decreased. Apoptotic and adaptive responses were preserved in both TNFR1-null and Fas-null mice. These results suggest that the mechanism for increased enterocyte apoptosis following massive SBR does not appear to involve the extrinsic, death receptor-mediated pathway.

Abstract
BACKGROUND/PURPOSE After small bowel resection (SBR), serum induces proliferation in rat intestinal epithelial cells (RIEC-6). This study was designed to elucidate the effects of postoperative time interval, site, and magnitude of SBR on RIEC-6 proliferation. METHODS Serum was collected from rats at various times after a 75% mid-SBR or sham operation and added to RIEC-6 cells and growth determined over 5 days. In other experiments, cell growth was recorded in the presence of serum from rats after 25%, 50%, or 75% SBR, or after jejunal or ileal SBR. RESULTS SBR serum enhanced RIEC-6 cell proliferation as early as 12 hours after resection. The extent of SBR directly correlated with the level of adaptation; however, the effects on cell growth by the serum were similar. SBR serum induced proliferation equally after either proximal or distal resection. CONCLUSIONS Serum contains a factor that stimulates intestinal cell proliferation soon after SBR but independent of the degree or site of intestinal resection. Although humoral factor(s) play a role in the early induction of enterocyte proliferation after SBR, further modulation of adaptation to varied lengths or sites of intestinal resection are probably governed by mechanisms independent of factors that circulate in the serum.

Abstract
After massive small bowel resection (SBR), the remnant intestine undergoes an adaptive process characterized by increases in wet weight, protein and DNA content, villus height and crypt depth, and absorptive surface area. These changes are the result of a proliferative stimulus that increases crypt cell mitosis and augments cellular progression along the villus axis. Functionally, there is upregulation of the Na(+)/glucose cotransporter, Na(+)/H(+) exchanger, and other enzymes involved in intestinal digestion and absorption. These physiologic events are a compensatory response to the sudden loss of digestive and absorptive capacity by the remnant intestine. A major consequence of inadequate intestinal adaptation is lifelong dependence on parenteral nutrition, which results ultimately in cholestatic liver dysfunction. Furthermore, adaptation may be associated with changes in intestinal permeability and an increased risk of bacterial translocation and sepsis. Several mediators thought to be integral to the postresection adaptive response have been proposed, including luminal nutrients, gastrointestinal secretions, and humoral factors. A thorough understanding of intestinal adaptation will be essential in the rational development of new and innovative therapies that amplify this complex but important process.

Abstract
BACKGROUND Surgical reversal of a small bowel segment has been proposed as a means to improve nutritional status in individuals with extensive bowel resection. However, clinical experience remains controversial. The aim of this study was to determine the effects of bowel segment reversal on intestinal adaptation and whole-body anabolism. METHODS Male Wistar rats underwent a 70% small bowel resection with (REV) or without (CON) reversal of a 5-cm small bowel segment (5 cm distal to resected segment), or sham-operation (SHAM). After surgery (day 0), rats were fed with powdered diet from day 2 to day 12. Body weight, nitrogen balance, carcass compositions, and serum concentrations of albumin and insulin-like growth factor (IGF)-1 were determined to assess whole-body anabolism. The composition and architecture of the small intestine were measured to assess the intestinal growth response. Serum concentrations of tumor-necrosis factor (TNF)-alpha and interleukin (IL)-6 were measured to assess the response of postoperative cytokines. RESULTS Surgical reversal significantly increased the intestinal protein and DNA contents in the proximal segment compared with surgical resection. REV rats had a significantly slower rate of weight gain and lower serum levels of albumin and IGF-1, and had significantly greater levels of circulating white blood cells, blood urea nitrogen, and IL-6 compared with CON and SHAM rats. There were no significant differences in serum concentrations of TNF-alpha and carcass percentages of water, protein, and fat among groups. CONCLUSIONS Small bowel segment reversal stimulates jejunal hyperplasia but the surgical reversal induced-elevation in serum IL-6 may eliminate the whole-body anabolism in massive bowel-resected rats.
