Abstract
L-arginine is an important factor in several physiological and biochemical processes. Recently, scientists studied L-arginine effect on inflammatory mediators such as C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). We conducted a systematic review on randomized controlled trials assessing L-arginine effect on inflammatory mediators. We searched data bases including Google scholar, ISI web of science, SCOPUS, and PubMed/Medline up to April 2019. Randomized clinical trials assessing the effect of L-arginine on inflammatory mediators in human adults were included. Our search retrieved eleven articles with 387 participants. Five articles were on patients with cancer and 6 articles were on adults without cancer. L-arginine was applied in enteral form in 5 articles and in oral form in 6 articles. Eight articles were on both genders, two articles were on women, and one article was on men. L-arginine could not reduce inflammatory mediators among patients with and without cancer except one article which indicated that taking L-arginine for 6 months decreased IL-6 among cardiopathic nondiabetic patients. Our results indicated that L-arginine might not be able to reduce selected inflammatory mediators, but for making a firm decision more studies are needed to be conducted with longer intervention duration, separately on male and female and with different doses of L-arginine.

Analysis of the associated factors for severe weight loss after minimally invasive McKeown esophagectomy. Thorac Cancer 2018; 10:209-218. [PMID: 30578600 PMCID: PMC6360231 DOI: 10.1111/1759-7714.12934] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2018] [Revised: 11/13/2018] [Accepted: 11/14/2018] [Indexed: 12/18/2022] Open
Abstract
Background This study investigated the risk factors for severe weight loss (SWL) within one year after minimally invasive McKeown esophagectomy. Methods Esophageal cancer patients who underwent McKeown esophagectomy between January and July 2017 were prospectively enrolled. Preoperative body weight (PBW) was chosen as the initial body weight. Results Forty‐four patients were enrolled and successfully followed up for one year. Median weight loss was 7.4% (quartile: 5.3–8.1%) and 12.6% (quartile: 8.8–17.7%) four weeks and one year after surgery, respectively. Accelerated weight loss occurred during the first two weeks after discharge, with median weight loss of 5.6% (quartile: 4.2–7.1%). Multivariable analysis showed that age ≥ 70 years (odds ratio [OR] 7.65; P = 0.030), preoperative sarcopenia (OR 7.18; P = 0.030), the first surgery in the daily schedule (OR 6.87; P = 0.032) and vocal cord paralysis (OR 12.30; P = 0.046) were independent risk factors for short‐term (4 weeks) SWL (> 7.5% PBW), while an American Society of Anesthesiologists score of 3–4 (OR 6.58; P = 0.047), a high fat‐free mass (OR 21.91; P = 0.003), and vocal cord paralysis (OR 25.83; P = 0.017) were independent risk factors for long‐term (1 year) SWL (> 13.0% PBW) after esophagectomy. Postoperative symptoms of insomnia, appetite loss, dysphagia, eating difficulties, and taste issues were also related to SWL. Conclusions In esophageal cancer patients who have undergone esophagectomy, the first two weeks after hospital discharge is a key period for nutrition intervention. Patients with associated factors for SWL require postoperative nutrition support.

Ann Thorac Surg 2018; 107:912-920. [PMID: 30403976 DOI: 10.1016/j.athoracsur.2018.09.048] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2018] [Revised: 08/04/2018] [Accepted: 09/24/2018] [Indexed: 01/11/2023]
Abstract
BACKGROUND The aim of the current study was to investigate the impact of early oral feeding (EOF) on inflammatory cytokine levels after McKeown minimally invasive esophagectomy (MIE) for cancer. METHODS This study was based on a randomized controlled trial (NCT01998230). Patients with esophageal cancer who received McKeown MIE were randomly allocated into a group that started oral feeding on postoperative day (POD) 1 (EOF group) or a second group that received nil by mouth until 7 days after operation (late oral feeding [LOF] group). We chose 86 patients, 46 patients in the EOF group and 40 patients in the LOF group, in which to analyze inflammatory cytokine levels (interleukin [IL]-6, IL-8, tumor necrosis factor-a [TNF-α], and monocyte chemotactic protein-1 [MCP-1]). RESULTS The EOF and LOF groups exhibited similar preoperative IL-6, IL-8 TNF-α, and MCP-1 levels. The levels of the four inflammatory cytokines at PODs 1 and 3 were significantly higher than the preoperative levels (all p < 0.001). At POD 5 the levels of all four inflammatory cytokines were decreased compared with those at PODs 1 and 3. At PODs 3 and 5 the levels of IL-6, IL-8, and TNF-α were significantly lower in the EOF group than in the LOF group (all p < 0.05). At POD 3 the MCP-1 levels in the EOF group were significantly lower than those in the LOF group (all p < 0.05). CONCLUSIONS Compared with conventional rehabilitation programs the EOF protocol may decrease stress response after McKeown MIE.

Abstract
Background To investigate the efficacy of amino acid administration via peripheral veins in addition to conventional enteral feeding following esophagectomy. Materials and methods Retrospective analysis of data pertaining to 33 patients with esophageal cancer who underwent radical esophagectomy and satisfied the required nutrition control. Patients were divided into the amino acid group (n = 17) and control group (n = 16). Primary outcomes were albumin (Alb) and prealbumin (PreAlb) levels, urinary 3-methylhistidine/creatinine (3-MeHis/Cre) ratios, nitrogen balance, and weight; postoperative complications were noted as secondary outcomes. Results Alb levels were significantly higher in the amino acid group on postoperative day (POD)-14 (3.4 ± 0.3 vs. 3.1 ± 0.4 mg/dL in the control group, p = 0.018) and at 1 month after surgery (3.8 ± 0.4 vs. 3.5 ± 0.3 mg/dL, p = 0.045). No significant differences were observed in PreAlb and urinary 3-MeHis/Cre rates between the treatment groups. Body weights at 3 months postoperatively were decreased by 6% and 3% in the control and amino acid groups, respectively. Conclusion Peripheral venous administration of amino acids soon after surgical stress is an effective method for nutritional control. Radical resection for esophageal cancer is a highly invasive procedure. Enteral feeding has been used in postoperative period for esophagectomy. Peripheral vein infusion of amino acids is effective for post esophagectomy.

Abstract
INTRODUCTION The ESPEN guideline presents a multidisciplinary focus on clinical nutrition in inflammatory bowel disease (IBD). METHODOLOGY The guideline is based on extensive systematic review of the literature, but relies on expert opinion when objective data were lacking or inconclusive. The conclusions and 64 recommendations have been subject to full peer review and a Delphi process in which uniformly positive responses (agree or strongly agree) were required. RESULTS IBD is increasingly common and potential dietary factors in its aetiology are briefly reviewed. Malnutrition is highly prevalent in IBD - especially in Crohn's disease. Increased energy and protein requirements are observed in some patients. The management of malnutrition in IBD is considered within the general context of support for malnourished patients. Treatment of iron deficiency (parenterally if necessary) is strongly recommended. Routine provision of a special diet in IBD is not however supported. Parenteral nutrition is indicated only when enteral nutrition has failed or is impossible. The recommended perioperative management of patients with IBD undergoing surgery accords with general ESPEN guidance for patients having abdominal surgery. Probiotics may be helpful in UC but not Crohn's disease. Primary therapy using nutrition to treat IBD is not supported in ulcerative colitis, but is moderately well supported in Crohn's disease, especially in children where the adverse consequences of steroid therapy are proportionally greater. However, exclusion diets are generally not recommended and there is little evidence to support any particular formula feed when nutritional regimens are constructed. CONCLUSIONS Available objective data to guide nutritional support and primary nutritional therapy in IBD are presented as 64 recommendations, of which 9 are very strong recommendations (grade A), 22 are strong recommendations (grade B) and 12 are based only on sparse evidence (grade 0); 21 recommendations are good practice points (GPP).

Abstract
Cholestasis in preterm infants has a multifactorial etiology. Risk factors include degree of prematurity, lack of enteral feeding, intestinal injury, prolonged use of parenteral nutrition (PN), and sepsis. Soy-based parenteral lipid emulsions have been implicated in the pathophysiology of PN-associated liver injury. Inflammation plays an important role. Medical therapies are used; however, their effects have not consistently proven effective. Evaluation of cholestasis involves laboratory work; direct bilirubin levels are used for diagnosis and trending. Adverse outcomes include risk for hepatobiliary dysfunction, irreversible liver failure, and death. Early enteral feedings as tolerated is the best way to prevent and manage cholestasis.

Abstract
BACKGROUND Proper artificial nutrition for patients who are unable to eat normally is an ongoing, unresolved concern in geriatric medicine and home medical care. Controversy surrounds prognostic differences between parenteral and enteral nutrition, 2 methods for artificial nutrition. OBJECTIVES Short-term outcomes of parenteral and enteral nutrition for patients who are unable to eat normally were compared and analyzed. DESIGN Data were acquired from patients selected from a national inpatient database covering 1057 hospitals in Japan. Participants had received artificial nutrition between April 2012 and March 2013, were aged ≥20 y, and did not have cancer. They were separated into 2 groups: those who received parenteral nutrition and those who received enteral nutrition. We performed one-to-one propensity score matching between the groups. The primary outcome measurements were mortality rates at 30 and 90 d after the start of the procedure. The secondary outcomes were postprocedural complications, pneumonia, and sepsis. We analyzed survival length of stay after the procedure with the use of a Cox proportional hazards model. RESULTS There were 3750 patients in the parenteral group and 22,166 patients in the enteral group. Propensity score matching created 2912 pairs in the 2 groups. Patients with a similar propensity score (probability of being assigned to the enteral group) calculated from the baseline condition were matched. Mortality rates at 30 and 90 d after start of treatment were 7.6% and 5.7% (P = 0.003) and 12.3% and 9.9% (P = 0.002) in the parenteral and enteral groups, respectively. In Cox regression analysis, the HR for the enteral group relative to the parenteral group was 0.62 (95% CI: 0.54, 0.71; P < 0.001). The incidences of postprocedural pneumonia and sepsis were 11.9% and 15.5% (P < 0.001) and 4.4% and 3.7% (P = 0.164) for the parenteral and enteral groups, respectively. CONCLUSION The present analysis showed the better survival rate with enteral compared with parenteral nutrition for adults who were not suffering from cancer. This trial was registered at clinicaltrials.gov as NCT02512224.

Abstract
BACKGROUND/AIM Development of hepatic dysfunction is a well-recognized complication of total parenteral nutrition in preterm infants. Previous studies reported the incidence of total parenteral nutrition-associated cholestasis and described possible contributing factors to its pathogenesis, but little is done trying to determine its possible predictive risk factors. The aims of this study was to determine the incidence of total parenteral nutrition-associated cholestasis and to develop a possible predictive model for its occurrence. PATIENTS AND METHODS A review of medical records of all very low birth weight infants admitted to neonatal intensive care unit at King Khalid University Hospital, Riyadh, Saudi Arabia, between January 2001 and December 2003 was carried out. The infants were divided into two groups: Cholestasis and noncholestasis, based on direct serum bilirubin level >34 μmol/L. A multivariate logistic regression analysis was performed to calculate the statistical significance of risk factors. Receiver-operating characteristic curve was used to determine the optimal cutoff points for the significant risk factors and to calculate their sensitivity and specificity. The level of significance was set at P ≤ 0.05. RESULTS A total of 307 patients were included in the analysis. The incidence of cholestasis in the whole population was 24.1% (74 patients). Infants with cholestasis had a lower birth weight, 735.4 ± 166.4 g vs. 1185.0 ± 205.6 g for noncholestasis group (P < 0.001), whereas the mean gestational age for the two groups was 25.4 ± 2.1 week and 28.9 ± 2.1 week, respectively (P < 0.001). The significant risk factors for the development of cholestasis were birth weight (P = 0.006) with an odds ratio of 0.99 [95% confidence interval (CI), 0.98, 0.99]; sensitivity of 92%, specificity of 87%; and total parenteral nutrition duration (P < 0.001) with an odds ratio of 1.18 (95% CI, 1.10, 1.27); sensitivity of 96%, specificity of 89%. CONCLUSIONS A lower birth weight and longer duration of total parenteral nutrition were strong predictive risk factors for the development of cholestasis in preterm infants.

Abstract
Enteral (EN) or parenteral (PN) nutrition is used to support critically ill patients until oral feeding resumes. Enteral nutrition is assumed preferable to PN, but the differential influence on immune function is not well defined. Autonomic nervous activity is known to influence innate immune responses, and we hypothesized that EN and PN could influence both autonomic signaling and gene activation in peripheral blood monocytes (PBMs). Ten subjects (aged 18-36 years) received continuous EN or PN for 72 h. Peripheral blood monocytes were isolated from whole blood before and after continuous feeding and were analyzed for gene expression using a microarray platform. Gene expression after feeding was compared from baseline and between groups. To measure autonomic outflow, subjects also underwent heart rate variability (HRV) monitoring during feeding. Time and frequency domain HRV data were compared between groups and five orally fed subjects for changes from baseline and changes over time. During continuous EN and PN, subjects exhibited declines in both time and frequency domain HRV parameters compared with baseline and with PO subjects, indicating a loss of vagal/parasympathetic tone. However, PN feeding had a much greater influence on PBM gene expression compared with baseline than EN, including genes important to innate immunity. Continuous EN and PN are both associated with decreasing vagal tone over time, yet contribute differently to PBM gene expression, in humans. These preliminary findings support assumptions that PN imposes a systemic inflammatory risk but also imply that continuous feeding, independent of route, may impart additional risk through different mechanisms.

Abstract
BACKGROUND The purpose of the study was to evaluate the utilization and morbidity associated with feeding jejunostomy tubes (JT) placed at the time of gastroesophageal resection (GER). METHODS Under institutional review board approval, a prospective database of patients undergoing GER from January 2004 to September 2010 was reviewed. Data analyzed included patient demographics, postoperative complications, JT use, and JT specific complications. Fisher's exact tests explored associations with utilization of a JT following resection. RESULTS Seventy-three patients (51 men, 22 women, median age of 59) underwent placement of a JT at the time of GER (total gastrectomy = 28, Ivor-Lewis = 28, subtotal gastrectomy = 8, proximal gastrectomy = 6, and transhiatal esophagectomy = 3) of both malignant (97%) and benign (3%) disease processes. Twenty-one JT specific complications (11 minor and 10 major) were identified. Reoperation was required in the management of two complications (small bowel obstructions), while all other complications were easily managed by an interventional radiologist (n = 8), bedside procedure (n = 5), or did not require intervention (n = 6). Eighty-six percent of patients were discharged tolerating a postgastrectomy diet, 10% nothing per orem, and 4% a liquid diet. Inpatient enteral nutrition (EN) was initiated in 68%, but continued on discharge in only 54% secondary to failure to thrive (54%), dysphagia (21%), anastomic leak (15%), chyle leak (3%), esophagostomy (3%), and duodenal stump leak (3%). The mean time to discontinuance of EN and removal of the JT was 44 days (range, 4-203) and 71 days (range, 15-337) respectively. Although only 13% (n = 5) of patients requiring adjuvant therapy were utilizing their JT at the commencement of therapy, 75% (n = 21) required EN during its course. The median time to adjuvant therapy was found to be slightly longer in those who required outpatient EN versus those who did not (61 vs. 90 days, p = 0.08). However, the median time to adjuvant therapy did not differ between those who were and were not receiving EN at the time of adjuvant therapy commencement (80 vs. 92 days, p = 0.2). Age (p = 0.4), number of co-morbidities (p = 0.2), preoperative percent body weight loss (p = 0.9), and clinical stage (p = 0.8) were not significantly associated with outpatient JT use. Patients who suffered a postoperative complication were most likely to require EN (p = 0.002), an association that strengthened as the number of complications increased (p = 0.0008). Although not statistically significant, a trend towards increased outpatient EN was noted in patients who underwent transhiatal esophagectomy and total gastrectomy (p = 0.06). CONCLUSIONS JT placement carries a considerable morbidity in patients undergoing GER. However, because it is difficult to preoperatively ascertain who will need prolonged EN, the routine placement of a JT is recommended, particularly in those who will likely require adjuvant therapy or are at high risk for postoperative complications. Despite patient desires for early removal of an unused JT, caution should be taken if adjuvant therapy is being considered.

Abstract
The provision of parenteral nutrition (PN) to ‘stressed’ patients often results in hyperglycaemia, which may be detrimental. In animal models limited amounts of enteral nutrition (EN) improve intestinal integrity and stimulate intestinal incretin production, which may lead to improved glucose control. We set out to assess if combining EN with PN results in improved glucose homeostasis rather than PN given alone. We conducted a randomised trial in a university teaching hospital of patients undergoing a ‘curative’ oesophagectomy for adenocarcinoma. Differences between the two intervention groups were assessed for continuous glucose measurement, insulin sensitivity using insulin tolerance tests (ITT) and homeostasis model analysis (HOMA), the incretin glucose-dependent insulinotropic polypeptide (GIP) and intestinal permeability. The combination of PN with EN resulted in lower interstitial glucose concentrations (P = 0·002), reduced insulin resistance, improved insulin sensitivity (HOMA-insulin resistance (IR)P = 0·045; HOMA βP = 0·037; ITTP = 0·006), improved intestinal permeability (P < 0·001) and increased GIP (P = 0·01) when compared with PN alone. The combination of EN with PN, when compared with PN alone, results in reduced glucose concentrations, reduced insulin resistance, increased incretins and improvements in intestinal permeability.

Abstract
In surgery, indications for artificial nutrition comprise prevention and treatment of catabolism and malnutrition. Thus in general, food intake should not be interrupted postoperatively and the re-establishing of oral (e.g. after anastomosis of the colon and rectum, kidney transplantation) or enteral food intake (e.g. after an anastomosis in the upper gastrointestinal tract, liver transplantation) is recommended within 24 h post surgery. To avoid increased mortality an indication for an immediate postoperatively artificial nutrition (enteral or parenteral nutrition (PN)) also exists in patients with no signs of malnutrition, but who will not receive oral food intake for more than 7 days perioperatively or whose oral food intake does not meet their needs (e.g. less than 60–80%) for more than 14 days. In cases of absolute contraindication for enteral nutrition, there is an indication for total PN (TPN) such as in chronic intestinal obstruction with a relevant passage obstruction e.g. a peritoneal carcinoma. If energy and nutrient requirements cannot be met by oral and enteral intake alone, a combination of enteral and parenteral nutrition is indicated. Delaying surgery for a systematic nutrition therapy (enteral and parenteral) is only indicated if severe malnutrition is present. Preoperative nutrition therapy should preferably be conducted prior to hospital admission to lower the risk of nosocomial infections. The recommendations of early postoperative re-establishing oral feeding, generally apply also to paediatric patients. Standardised operative procedures should be established in order to guarantee an effective nutrition therapy.

Abstract
BACKGROUND One of the most common complications in infants under parenteral nutrition treatment is parenteral nutrition-associated cholestasis (PNAC). The etiology of PNAC is thought to be multifactorial. The aims of this study were to evaluate the risk factors for PNAC in our neonatal intensive care unit and determine useful predictors. METHODS This study enrolled premature infants (gestational age <36 weeks) who were admitted to our neonatal intensive care unit and treated with parenteral nutrition infusion for at least 2 weeks between January 2004 and January 2007. Multiple possible risk factors were analyzed by a retrospective review study design. PNAC was defined as direct bilirubin greater than 1.5 mg/dL during parenteral nutrition. RESULTS A total of 62 premature infants with prolonged course of parenteral nutrition were eligible for this study; 11 (17.74%) of the infants developed PNAC. There were significant differences in terms of gestational age, birth body weight, duration of parenteral nutrition, septic episodes, and average energy intake during the 2nd and 3rd weeks of life between infants with cholestasis and those without cholestasis. Of these risk factors, the duration of parenteral nutrition was most significant after multivariate logistic regression analysis. CONCLUSION Young gestational age, low birth body weight, more sepsis episodes, and long duration of parenteral nutrition were significant risk factors for PNAC in our study. Low energy intake during the 2nd and 3rd weeks of life is a predictor for PNAC.

Abstract
BACKGROUND Parenteral nutrition (PN) increases post-trauma pneumonia versus enteral feeding. PN impairs murine immunoglobulin A (IgA) airway defenses and abrogates a normal IgA increase following injury. This work investigates the effect of type/route of nutrition on lung IgA and its transport protein, polymeric immunoglobulin receptor (pIgR), after injury. METHODS Catheterized mice were randomized to Chow or PN for 5 days and sacrificed without injury (Chow: n = 12; PN n = 11), or 8 hours after laparotomy + neck incisions (Chow-injury: n = 11, PN-injury: n = 13). Bronchoalveolar lavage (BAL) and lung IgA levels were analyzed by enzyme-linked immunosorbent assay (ELISA) and lung pIgR by Western blot. RESULTS BAL IgA levels increased in Chow-injury versus PN-injury (P <.01) with no differences in pIgR. PN-injury tissue IgA levels decreased versus Chow (P <.01), Chow-injury (P <.01), and PN (P <.05). CONCLUSIONS PN impairs the airway IgA response to injury but not due to impaired IgA transport capacity/pIgR level.

Abstract
BACKGROUND Parenteral nutrition (PN) increases the incidence of pneumonia in severely injured patients compared with enteral feeding (ENT). Injury induces an innate airway IgA response in severely injured patients; similar responses occur in mice. Tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 beta (IL-1beta) stimulate the production of polymeric immunoglobulin receptor (pIgR), the protein required to transport immunoglobulin A (IgA) to mucosal surfaces. We have shown that PN alters levels of lung and nasal passage IgA and several IgA-stimulating cytokines. We hypothesized that TNF-alpha and IL-1beta blockade, as well as PN, would blunt the airway IgA response to injury. METHODS Male Institute of Cancer Research (ICR) mice were randomized to uninjured controls (n = 10) or to intra-peritoneal phosphate-buffered saline (PBS) (n = 9), antagonistic TNF-alpha antibody (100 mcg, n = 7), or antagonistic IL-1beta antibody (50 mcg, n = 8) 30 min prior to surgical stress with laparotomy and neck incisions. Mice were sacrificed at 8 h for nasal and bronchoalveolar lavage (NAL, BAL) to measure IgA by enzyme-linked immunosorbent assay. In a separate experiment, 12 mice underwent intravenous cannulation followed by chow (n = 5) or PN (n = 7) feeding for 5 days prior to the same stress and IgA measurement. RESULTS Injury significantly increased NAL and BAL IgA (225 +/- 104 ng) compared with baseline (145 +/- 38 ng; p = 0.01). Blockade of TNF-alpha eliminated the innate airway IgA response to injury (130 +/- 47 ng; p = 0.01), whereas IL-1beta blockade blunted and PN eliminated it completely. CONCLUSIONS Tumor necrosis factor-alpha is involved in the respiratory IgA immune response to injury. Both TNF-alpha blockade and PN impair this innate response, and blockade of IL-1beta impairs it to a degree. We hypothesize that these cytokines blunt this response via their known effects on the polymeric immunoglobulin receptor (pIgR), whereas the PN-induced deficit likely is multifactorial.

Abstract
OBJECTIVE The surgical treatment of aortoesophageal fistulae (AEF) has a high morbidity and mortality rate. We report our experience with the sequential use of endovascular thoracic stentgrafts and cryopreserved aortic homografts for in situ repair of the descending thoracic aorta. METHODS In a 7-year period, 6 patients with AEF were treated at our center. After primary endovascular repair in all cases, 4 patients subsequently underwent in situ repair of the descending thoracic aorta with cryopreserved homografts. Long-term antibiotic therapy was given in all cases. Recent clinical status and radiologic findings on follow-up studies of each patient were analyzed. The mean follow-up time was 35 months (range, 2-76). RESULTS Endovascular stentgraft repair was technically successful in all cases. Two patients were not candidates for open surgical repair because of their medical condition; they both died within 8 weeks after discharge from the hospital, 1 from recurrent septic episodes, and the other from upper gastrointestinal bleeding. One of 4 patients who had undergone open surgical repair died 1 year later from upper gastrointestinal bleeding that occurred presumably due to an infectious degeneration of the homograft after secondary infection with a methacillin-resistant Staphyloccocus aureus. In 1 case persistent paraplegia and in another case persistent renal failure occurred. CONCLUSION The use of cryopreserved homografts is a valuable alternative to in situ repair with prosthetic vascular grafts or extra-anatomic reconstructions in the surgical treatment of AEF. Endovascular stentgraft placement plays a role as a bridging procedure in emergency situations.

Abstract
OBJECTIVE Although immune dysfunction in patients with cancer could be multifactorial, the immune system may be modulated by nutritional substrates and genetic background. Our study evaluated the effect of G308A polymorphism of the tumor necrosis factor-alpha (TNF-alpha) gene on inflammatory markers in patients after surgery for head and neck cancer who received early enteral nutrition. METHODS A population of 60 patients with oral and laryngeal cancer was enrolled. At surgery patients were treated with a hyperproteic enteral diet. Perioperatively and on postoperative day 6 the following parameters were evaluated: serum values of prealbumin, transferrin, total number of lymphocytes, interleukin-6, TNF-alpha, and C-reactive protein. In addition, genotyping of G308A gene polymorphism was assessed. RESULTS Patients' mean age was 61.1 +/- 14.6 y (four women, 56 men) with a body mass index of 25.4 +/- 5.2 kg/m(2) and a previous weight loss of 0.35 +/- 0.2 kg. Forty patients (37 men, 3 women; 66.6%) had the genotype G308/G308 (wild group) and 20 patients (19 men, 1 woman; 23.4%) had the genotype G308/A308 (mutant group). A significant increase in prealbumin and transferrin levels was detected in both groups. C-reactive protein decreased in both groups (wild group: 105.1 +/- 60 versus 53.8 +/- 62.3 mg/dL, P < 0.05; mutant group: 99.5 +/- 46 versus 43.9 +/- 51.9 mg/dL, P < 0.05). Interleukin-6 decreased in both groups (wild group: 20.1 +/- 22 versus 6.2 +/- 4.1 pg/mL, P < 0.05; mutant group: 22.3 +/- 38 versus 9.2 +/- 7.4 pg/mL, P = NS). Lymphocytes increased in both groups (wild group: 1102 +/- 468 versus 1600 +/- 537 10(3)/mL, P = NS; mutant group: 1441 +/- 739 10(3)/mL versus 1669 +/- 614 10(6)/mL, P = NS). TNF-alpha showed no changes. CONCLUSION The G308A polymorphism of the TNF-alpha gene did not affect levels of inflammatory markers in patients after surgery for head and neck cancer who were treated with early enteral nutrition.

Abstract
Oesophagectomy is still characterized by a high postoperative mortality and respiratory morbidity. Nevertheless, epidemiological, medical and surgical advances have improved the management of this surgical procedure. The anaesthesiologist influence is present at each level, from the preoperative evaluation to the management of postoperative complications. The preoperative period is improved by the use of assessment scores, the better knowing of respiratory risk factors and of the neoadjuvant therapy adverse effects. The main objective of the operative period is to ensure a rapid weaning procedure and stability of the respiratory and haemodynamic functions, warranting the anastomotic healing. The interest of the association between respiratory rehabilitation and thoracic epidural analgesia is highlighted in the postoperative period. The management of postoperative complications, mainly represented by respiratory failure and anastomotic leakages, requires a multidisciplinary analysis. The potential interest of non-invasive ventilation and of the modulation of postoperative inflammatory response needs further investigation.

Abstract
Although the central focus of acute respiratory distress syndrome (ARDS) is the pathology within the lung, ARDS is very much a systemic disease. As such, the whole body needs care and support while the disease process within the lung runs its course. The issues of pain management, sedation, fluid balance, nutrition, metabolic and hormonal processes, infection control, and patient positioning are important for any patient in a critical care setting. For patients with ARDS, the required ventilatory support and ARDS-associated systemic inflammation mandate the above supportive measures.

Abstract
Enhanced recovery of patients after surgery ("ERAS") has become an important focus of perioperative management. From a metabolic and nutritional point of view, the key aspects of perioperative care include: Enteral nutrition (EN) by means of oral nutritional supplements (ONS) and if necessary tube feeding (TF) offers the possibility of increasing or ensuring nutrient intake in cases where food intake is inadequate. These guidelines are intended to give evidence-based recommendations for the use of ONS and TF in surgical patients. They were developed by an interdisciplinary expert group in accordance with officially accepted standards and are based on all relevant publications since 1980. The guideline was discussed and accepted in a consensus conference. EN is indicated even in patients without obvious undernutrition, if it is anticipated that the patient will be unable to eat for more than 7 days perioperatively. It is also indicated in patients who cannot maintain oral intake above 60% of recommended intake for more than 10 days. In these situations nutritional support should be initiated without delay. Delay of surgery for preoperative EN is recommended for patients at severe nutritional risk, defined by the presence of at least one of the following criteria: weight loss >10-15% within 6 months, BMI<18.5 kg/m(2), Subjective Global Assessment Grade C, serum albumin <30 g/l (with no evidence of hepatic or renal dysfunction). Altogether, it is strongly recommended not to wait until severe undernutrition has developed, but to start EN therapy early, as soon as a nutritional risk becomes apparent.

Abstract
AIM: To investigate the intestinal barrier function damage induced by trauma and infection in rats.
METHODS: Experimental models of surgical trauma and infection were established in rats. Adult Sprague-Dawley rats were divided into 4 groups: control group (n = 8), EN group (n = 10), PN group (n = 9) and Sep group (n = 8). The rats in PN and Sep groups were made into PN models that received isonitrogenous, isocaloric and isovolumic TPN solution during the 7-d period. Rats in EN and Sep groups received laparotomy and cervical catheterization on day 1 and received lipopolysaccharide injection intraperitoneally on d 7. On the 7th day all the animals were gavaged with lactulose and mannitol to test the intestinal permeability. Twenty-four hours later samples were collected and examined.
RESULTS: The inflammatory responses became gradually aggravated from EN group to Sep group. The mucosal structure of small intestine was markedly impaired in PN and Sep groups. There was a low response in IgA level in Sep group when compared with that of EN group. Lipopolysaccharide injection also increased the nitric oxide levels in the plasma of the rats. The intestinal permeability and bacterial translocation increased significantly in Sep group compared with that of control group.
CONCLUSION: One wk of parenteral nutrition causes an atrophy of the intestinal mucosa and results in a moderate inflammatory reaction in the rats. Endotoxemia aggravats the inflammatory responses that caused by laparotomy plus TPN, increases the production of nitric oxide in the body, and damages the intestinal barrier function.

Abstract
The association of malnutrition with surgical morbidity and mortality is well recognized. The question of whether this relationship is causal or simply an association in sick patients has been hotly debated. The field of nutrition support has grown out of the belief that correcting malnutrition will modify associated risks for poor outcome. It has been easier to substantiate this belief in some clinical situations than in others. The evidence for nutrition support during the perioperative period is reviewed and recommendations are made about where nutrition support is most useful and where it may be counterproductive. Some of the important unanswered questions about perioperative nutrition support are raised.

Abstract
PURPOSE OF REVIEW Much of the morbidity and mortality of severely burned patients is connected with hypermetabolism and catabolism with its accompanying impairment of wound healing and increased infection risks. In order to prevent the erosion of body mass, nutritional support and other strategies to prevent catabolism have become a major focus in the care of severely burned patients. RECENT FINDINGS Major themes discussed in recent literature are dealing with enteral versus parenteral nutrition and gastric versus duodenal feeding. The possibility of overfeeding is another important aspect of high calorie nutrition as commonly used in burned patients. Specific formulas for enteral nutrition for specific metabolic abnormalities are under evaluation as well as the role of anabolic and anticatabolic agents. SUMMARY From the clinical literature, total enteral nutrition starting as early as possible without any supplemental parenteral nutrition is the preferred feeding method for burned patients. Using a duodenal approach, especially in the early postburn phase, seems to be superior to gastric feeding. Administration of high calorie total enteral nutrition in any later septic phase should be critically reviewed due to possible impairment of splanchnic oxygen balance. Therefore, measurement of CO(2)-gap should be considered as a monitoring method during small bowel nutrition. The impact on the course of disease of supplements such as arginine, glutamine and vitamins as well as the impact of the use of anabolic and anticatabolic agents is not yet evident. Furthermore, the effect of insulin administration and low blood sugar regimes on wound healing and outcome in burned patients should be evaluated in future studies.

Abstract
AIM: To investigate the safety, rationality and the practicality of enteral nutritional (EN) support in the postoperative patients with damaged liver function and the protective effect of EN on the gut barrier.
METHODS: 135 patients with liver function of Child B or C grade were randomly allocated to enteral nutrition group (EN, 65 cases), total parenteral nutrition group (TPN, 40 cases) and control group (CON, 30 cases). Nutritional parameters, hepatic and kidney function indexes were measured at the day before operation, 5th and 10th day after the operation respectively. Comparison was made to evaluate the efficacy of different nutritional support. Urinary concentrations of lactulose (L) and mannitol (M) were measured by pulsed electrochemical detection (HPLC-PED) and the L/M ratio calculated to evaluate their effectiveness on protection of gut barrier.
RESULTS: No significant damages in hepatic and kidney function were observed in both EN and TPN groups between pre- and postoperatively. EN group was the earliest one reaching the positive nitrogen balance after operation and with the lowest loss of body weight and there was no change in L/M ratio after the operation (0.026 ± 0.004) at the day 1 before operation, 0.030 ± 0.004 at the day 5 postoperative and 0.027 ± 0.005 at the day 10 postoperative), but the change in TPN group was significant at the day 5 postoperative (0.027 ± 0.003 vs 0.038 ± 0.009, P < 0.01).
CONCLUSION: EN is a rational and effective method in patients with hepatic dysfunction after operation and has significant protection effect on the gut barrier.

Abstract
BACKGROUND Complications after esophagectomy may prevent oral intake, lead to dependence on total parenteral nutrition, and lengthen hospital stay. Direct percutaneous endoscopic placement of a jejunostomy tube allows enteral feeding in the presence of postoperative complications and eliminates the need for total parenteral nutrition. METHODS A total parenteral nutrition database was used to identify patients who received total parenteral nutrition because of complications after esophagectomy. Records of all patients subsequently referred for percutaneous endoscopic jejunostomy placement were reviewed. RESULTS Twenty-five patients with postesophagectomy complications were referred for percutaneous endoscopic jejunostomy placement. A percutaneous endoscopic jejunostomy was successfully placed in 21 patients (84%), all of whom were weaned off total parenteral nutrition. Six patients (29%) in whom percutaneous endoscopic jejunostomy placement was successful died during hospitalization at a mean of 20 days (range 5-40 days) after the procedure for reasons unrelated to percutaneous endoscopic jejunostomy tube insertion. The remaining 15 patients were discharged while receiving nutrition by means of the percutaneous endoscopic jejunostomy. Ten of them had subsequent removal of the percutaneous endoscopic jejunostomy at a mean of 131 days (range 20-281 days). There were no major percutaneous endoscopic jejunostomy-related complications. Minor complications occurred in 4 patients (19%). CONCLUSION Percutaneous endoscopic jejunostomy placement may be considered in patients with complications after esophagectomy. In these patients, percutaneous endoscopic jejunostomy placement avoids the need for total parenteral nutrition.

Abstract
Malnutrition is a common and significant problem in patients with cancer. Enteral nutrition support is an important therapy and is preferred over parenteral nutrition in the setting of a functional gastrointestinal tract. Familiarity with the indications for enteral support, the choice of an enteral access device, and the selection of an enteral formula are critical for the care of patients with cancer and malnutrition. Enteral nutrition has proven efficacy in patients receiving radiation to the head and neck, those with persistent dysphagia, and critically ill patients with impaired gastric emptying. Placement of feeding tubes through the nose or percutaneously provides a mechanism to deliver nutrients when proximal obstructions or oropharyngeal dysphagia prevent adequate oral intake. Direct access to the jejunum can be safely obtained endoscopically and is very useful in patients who require enteral nutrition support following a gastrectomy or esophagectomy or have impaired gastric emptying. Standard polymeric formulas are appropriate for most patients. Specialized formulas designed to enhance immune function may decrease infectious complications but do not improve survival.

Abstract
OBJECTIVE It is known that the immune system is frequently affected in patients with head and neck cancer. Although immune dysfunction could be multifactorial, this immune system may be modulated by specific nutritional substrates, such as arginine. The aim of our study was to evaluate the effect of enteral nutrition supplemented with arginine on c-reactive protein (CRP), interleukin 6 (IL-6) and tumour necrosis factor (TNFalpha) in surgical head and neck cancer patients. DESIGN Randomized trial. SETTING Tertiary care. SUBJECTS A population of 36 patients with oral and laryngeal cancer were enrolled. INTERVENTIONS At surgery patients were randomly allocated to two groups: (a) patients receiving an enteral diet supplements with arginine and dietary fibre (group I, n=18); (b) patients receiving an isocaloric, isonitrogenous enteral formula (group II, n=18). Perioperatively and on postoperative day 5 the following parameters were evaluated: serum values of prealbumin, transferrin, albumin, total number of lymphocytes, interleukin 6, tumour necrosis factor alpha and c-reactive protein. RESULTS The mean age was 59.6+/-10.9 y (two females/34 males). No significant intergroup differences in the trend of the three plasma proteins and weight were detected. CRP decreased in both groups (group I: 152.9+/-76.9 vs 68.9+/-82.5 mg/dl; P<0.05; and group II: 105.9+/-92 vs 43.6+/-59.1 mg/dl; P<0.05). Interleukin 6 did not change (group I: 16.3+/-12.3 vs 35.6+/-83.4 pg/ml; NS; and group II: 22.8+/-40 vs 9.9+/-17.7 pg/ml; NS). TNFalpha did not show any differences (group I: 4.6+/-1.6 vs 5.1+/-1.5 pg/ml; NS; and group II: 8.8+/-6.1 vs 5.8+/-1.7 pg/ml; NS). Lymphocytes increased in both groups (group I: 1405.6+/-517 vs 1634+/-529 x 10(6)/ml; P<0.05; and group II: 1355+/-696 vs 1561+/-541 x 10(6)/ml; P<0.05). CONCLUSIONS Enhanced formula did not change IL6 and TNFalpha levels. Further studies are needed to determine whether route of nutrition or type of formula is the key in these patients.

Abstract
OBJECTIVE To compare the outcomes of intensive care unit patients fed through a nasogastric vs. a nasal-small-bowel tube including the time from tube placement to feeding, time to reach goal rate, and adverse events. DESIGN Sixty patients were prospectively randomized to receive gastric or small-bowel tube feedings. Nursing staff attempted to place a feeding tube in the desired position, and placement was confirmed radiographically after each bedside attempt. After two unsuccessful attempts, the feeding tube was placed under fluoroscopy. Feedings were started at 30 mL/hr and advanced to the patient's specific goal rate. SETTING Twenty-bed medical intensive care unit. PATIENTS Sixty medical patients admitted/transferred to the intensive care unit. INTERVENTIONS Tube feeds were held for 2 hrs if any residual was >200 mL. MEASUREMENTS Times were recorded at the initial tube insertion, onset of feeding, achievement of goal rate, and termination of feeding. Adverse outcomes included witnessed aspiration, vomiting, and clinical/radiographic evidence of aspiration. Patients were followed up for the duration of feeding, until leaving the intensive care unit, or for a maximum of 14 days. MAIN RESULTS Patients fed in the stomach received nutrition sooner from initial placement attempt (11.2 hrs vs. 27.0 hrs) and with fewer attempts (one vs. two) than those fed in the small bowel. Patients achieve goal rate sooner (28.8 hrs vs. 43.0 hrs) with gastric feeding compared with small-bowel feeding. There was no difference in aspiration events. CONCLUSIONS Gastric feeding demonstrates no increase in aspiration or other adverse outcomes compared with small-bowel feeding in the intensive care unit. Gastric feeding can be started and advanced to goal sooner with fewer placement attempts than small-bowel feeding.

Abstract
UNLABELLED Postoperative myocardial ischemia (POMI) is prevalent among patients after major noncardiac surgery. Surgery, as well as POMI, may modulate the immune system, potentially worsening patient outcome. We sought to investigate the modulation of soluble interleukin (IL)-6 and IL-10 by POMI and its association with increased postoperative infection rates. Two-hundred-three patients undergoing elective major abdominal, vascular, and orthopedic surgery participated in this prospective observational study. Perioperative management was standardized. Hemodynamic variables were kept within 20% of baseline. POMI was assessed by Holter electrocardiography starting at least 8 h before the induction of anesthesia and continued until 96 h after surgery. Twelve-lead electrocardiograms, cardiac enzymes, and immune variables were obtained at the time of admission to the hospital, before surgery, before the induction of anesthesia, after surgery, at the time of admission to the intensive care unit, and 6, 12, 18, 24, 36, 48, 72, 96, 120, 144, and 168 h after surgery. Infections were diagnosed according to the Centers for Disease Control criteria. The incidence of POMI was 27%, and the majority of cases (76%) occurred within the first 24 h after surgery. IL-6 and IL-10 levels significantly increased during surgery but did not differ between the POMI and Non-POMI groups. However, in the subset of patients who developed severe infections or sepsis (n = 47) a median of 3 days (range, 1-8 days) after surgery, the intraoperative increases of IL-6 and IL-10 in the POMI group were, respectively, 3 and 10 times higher compared with the increase in the Non-POMI group. By using a multifactorial analysis in these patients with severe infections, the type of surgical trauma was associated with an increased IL-6 response, whereas the increase in IL-10 was attributed to POMI. These findings suggest that immediate cytokine responses due to POMI and type of surgery might be relevant for the later onset of severe infections and sepsis. IMPLICATIONS Postoperative myocardial ischemia (POMI) occurred in 27% of patients after major noncardiac surgery. This was associated with an immediate augmented cytokine response in the first 12 h after surgery in patients who developed severe infections or sepsis 3 days later. POMI was associated with an increased interleukin (IL)-10 response, whereas IL-6 was associated with the type of surgery.

Abstract
Despite the increasing obesity of the American population, many chronically ill patients are malnourished. When this malnutrition is combined with the hypermetabolic response and protein catabolism of an acute event, such as an operation, nutritional support becomes an important facet for optimal critical care. This chapter reviews the basic tenants of nutritional support with special emphasis on patients with pulmonary compromise. Important aspects of caloric and protein support are discussed and enteral nutrition is emphasized because of its numerous advantages and documented improvement in outcome.

Abstract
Parenteral nutrition is a life-saving therapy for patients with intestinal failure. It may be associated with transient elevations of liver enzyme concentrations, which return to normal after parenteral nutrition is discontinued. Prolonged parenteral nutrition is associated with complications affecting the hepatobiliary system, such as cholelithiasis, cholestasis, and steatosis. The most common of these is parenteral nutrition-associated cholestasis (PNAC), which may occur in children and may progress to liver failure. The pathophysiology of PNAC is poorly understood, and the etiology is multifactorial. Risk factors include prematurity, long duration of parenteral nutrition, sepsis, lack of bowel motility, and short bowel syndrome. Possible etiologies include excessive caloric administration, parenteral nutrition components, and nutritional deficiencies. Several measures can be undertaken to prevent PNAC, such as avoiding overfeeding, providing a balanced source of energy, weaning parenteral nutrition, starting enteral feeding, and avoiding sepsis.

Abstract
Gut-associated lymphoid tissue is the dominant site for the initiation of mucosal immune response. Mucosal immunity depends on regulatory signals; nutritional elements, including fats, amino acids, and micronutrients, are critical cofactors for these signals. Nutrients specifically affect lymphocyte influx and migration, mononuclear cell activation, and the differentiated expression of immune response. The molecular basis of nutrient action has been shown to involve effects on receptor regulation, adhesion molecule expression, and the pattern of cytokine production. The gastrointestinal mucosal immune system is the major site for host interaction with microbes and provides a barrier against systemic access for food antigens and microbes. Nutrient metabolism has unique and direct impact on the host defense system of gut-associated lymphoid tissue and therefore has potential for widely disseminated impact on systemic immune response.

Abstract
T helper type 1 (Th1) lymphocytes secrete secrete interleukin (IL)-2, interferon-gamma, and lymphotoxin-alpha and stimulate type 1 immunity, which is characterized by intense phagocytic activity. Conversely, Th2 cells secrete IL-4, IL-5, IL-9, IL-10, and IL-13 and stimulate type 2 immunity, which is characterized by high antibody titers. Type 1 and type 2 immunity are not strictly synonymous with cell-mediated and humoral immunity, because Th1 cells also stimulate moderate levels of antibody production, whereas Th2 cells actively suppress phagocytosis. For most infections, save those caused by large eukaryotic pathogens, type 1 immunity is protective, whereas type 2 responses assist with the resolution of cell-mediated inflammation. Severe systemic stress, immunosuppression, or overwhelming microbial inoculation causes the immune system to mount a type 2 response to an infection normally controlled by type 1 immunity. In such cases, administration of antimicrobial chemotherapy and exogenous cytokines restores systemic balance, which allows successful immune responses to clear the infection.
