Abstract
Introduction Objective: to assess the effectiveness of immunonutrition (IN) compared to standard nutritional formulas in patients undergoing gastric cancer surgery. Material and methods: this is a real-life, observational retrospective cohort study. It included 134 patients, all of whom underwent gastrectomy at Montecelo Hospital between December 2019 and December 2022. Group A (N = 79 patients) received standard nutrition, and Group B (N = 55 patients) received formulas containing arginine, nucleotides, omega-3 fatty acids, and extra virgin olive oil. This protocol was carried out both pre and postoperatively for an average period of 10 days. The study evaluated hospital stay, the need for parenteral nutrition (PN), postoperative complications, as well as anthropometric and laboratory variables. Statistical analyses were performed using Stata 16.1.® Results: in the IN group compared to the standard nutrition group, the hospital stay was reduced by 34 % (p < 0.001). The number of patients requiring PN decreased by 21.1 % (p = 0.022), and its duration also decreased by 33.2 % (p < 0.001). The risk of infectious complications was lower with IN, specifically 70.1 % less (p < 0.001). As for other postoperative complications, IN reduced the risk of intestinal obstruction by 84 % (p < 0.002), suture dehiscence by 90.9 % (p < 0.001), blood transfusion by 99.8 % (p < 0.001), pleural effusion by 90.9 % (p = 0.021), acute renal failure by 84.02 % (p = 0.047), and surgical re-intervention by 69.93 % (p < 0.011). In the IN group, there was less weight loss (p = 0.048) and a smaller decrease in postoperative albumin (p = 0.005) and cholesterol (p < 0.001). Conclusion: immunonutrition reduces postoperative complications, decreases hospital stay, and optimizes nutritional outcomes.

Abstract
BACKGROUND Malnutrition, in patients with solid tumors, is associated with a worse clinical outcome and about 40% of patients affected by head and neck cancers (HNC) are malnourished at the time of cancer diagnosis. We investigated the potential benefit of a standardized immunonutritional protocol (INP) to patients with HNC receiving major ablative surgery. METHODS An observational study was conducted enrolling 199 patients: 50 treated with the INP and 149 with standard enteral nutrition. Complication rates, need for medications, and costs were considered as outcomes. RESULTS INP played a protective role in development of major surgical complications (OR 0.23, p = 0.023), albumin administration (RR 0.38, p = 0.018), and antibiotic duration (p < 0.001) and is cost-effective in patients with moderate or severe malnutrition (-6083€ and -11 988€, p < 0.05). CONCLUSIONS Our study supports the utility of INP, and accurate nutritional screening can help to identify malnourished patients who would receive the most benefits from this protocol.

Abstract
Current studies on inhibitory effects of n-3 PUFA on pro-inflammatory cytokines have inconsistent results. Thus, a meta-analysis of randomised controlled trials was conducted to identify the effects of n-3 PUFA administration on circulating IL-6 and TNF in patients with cancer. Studies that examined the effects of n-3 PUFA administration on circulating IL-6 and TNF in patients with cancer were identified by searching PubMed and EMBASE from January 1975 to February 2021. Differences in n-3 PUFA administration and control conditions were determined by calculating standardised mean differences (SMD) with 95 % CI. Twenty studies involving 971 patients met the inclusion criteria. The overall SMD were 0·485 (95 % CI 0·087, 0·883) for IL-6 and 0·712 (95 % CI 0·461, 0·962) for TNF between n-3 PUFA administration and control conditions. Sources of heterogeneity were not found through subgroup and meta-regression analyses. Publication bias was observed in TNF with a slight contribution to the effect size. n-3 PUFA can reduce circulating IL-6 and TNF levels in patients with cancer. Results supported the recommendation of n-3 PUFA as adjuvant therapy for patients with cancer, possibly excluding head and neck cancer, owing to their anti-inflammatory properties.

Abstract
Background Traumatic brain injury is a public health concern and is the main cause of death among various types of trauma. The inflammatory conditions due to TBI are associated with unfavorable clinical outcomes. Taurine has been reported to have immune-modulatory effects. Thus, the aim of this study was to survey the effect of taurine supplementation in TBI patients. Methods In this study, 32 patients with TBI were randomized into two groups. The treatment group received 30 mg/kg/day of taurine in addition to the Standard Entera Meal and the control group received Standard Entera Meal for 14 days. Prior to and following the intervention, the patients were investigated in terms of serum levels of IL-6, IL-10, hs-CRP and TNF-α as well as APACHEII, SOFA and NUTRIC scores, Glasgow coma scale and weight. In addition, the length of Intensive Care Unit stay, days of dependence on ventilator and 30-day mortality were studied. SPSS software (version 13.0) was used for data analysis. Results Taurine significantly decreased the serum levels of IL-6 (p = 0.04) and marginally APACHEII score (p = 0.05). In addition, weight loss was significantly lower in taurine group (p = 0.03). Furthermore, taurine significantly increased the GCS (p = 0.03). The groups were not different significantly in terms of levels of IL-10, hs-CRP, and TNF-α, SOFA and NUTRIC scores, 30-day mortality, length of ICU stay and days of dependence on ventilator. Conclusion According to the results of the present study, taurine supplementation can reduce the IL-6 levels as one of the important inflammatory markers in these patients; and enhances the clinical outcomes too.

Abstract
ABSTRACTSOmega-3 polyunsaturated fatty acids (PUFAs) possess anti-inflammatory properties. There is a lack of consensus regarding the effects of omega-3 PUFAs on C-reactive protein (CRP), a marker of systemic inflammation, in cancer patients. Herein, a meta-analysis of randomized controlled trials was conducted to evaluate the effects of omega-3 PUFAs on CRP levels in patients with cancer. PubMed and EMBASE were searched until May 2020 to identify randomized controlled trials that examined the effects of omega-3 PUFA administration on CRP levels in cancer patients. Standardized mean differences (SMDs) with their 95% confidence intervals (CIs) were calculated to determine the differences in omega-3 PUFA administration and control conditions. Seventeen eligible studies involving 916 cancer patients were included in this meta-analysis. Significant heterogeneity was present among individual studies (Pheterogeneity = 0.000; I2 = 74.5%). The overall SMDs of CRP levels between omega-3 PUFA administration and control conditions were 0.628 (95% CI: 0.342-0.914) and 0.456 (95% CI: 0.322-0.590) by the random-effect and fixed-effect models, respectively. Sources of heterogeneity were not found through subgroup and meta-regression analyses. Existing publication bias contributed slightly to the effect size. Omega-3 PUFAs can reduce systemic inflammation, as indicated by CRP levels in cancer patients. The use of omega-3 PUFAs is recommended for cancer patients due to their anti-inflammatory properties.

N-3 Long-Chain Polyunsaturated Fatty Acids, Eicosapentaenoic and Docosahexaenoic Acid, and the Role of Supplementation during Cancer Treatment: A Scoping Review of Current Clinical Evidence. Cancers (Basel) 2021; 13:cancers13061206. [PMID: 33801979 PMCID: PMC8000768 DOI: 10.3390/cancers13061206] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Revised: 03/02/2021] [Accepted: 03/06/2021] [Indexed: 01/07/2023] Open
Abstract
Simple Summary There has been extensive research into the beneficial anticancer effects of n-3 long-chain polyunsaturated fatty acids (LCPUFA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in preclinical models of cancer. However, clinical evidence is limited. The aim of this scoping review was to summarize the current clinical evidence of n-3 LCPUFA supplementation in cancer treatment and highlight areas where more clinical evidence is needed. We summarized the results of 57 clinical trials with an EPA/DHA intervention and determined that supplementation could improve a variety of outcomes important to the patient and the disease process, including immune system modulation, improved weight maintenance and increased disease-free or progression-free survival. There is, however, a need for larger, well-controlled, statistically powered randomized controlled trials to move n-3 supplementation to clinical practice. Abstract This scoping review examines the evidence for n-3 long-chain polyunsaturated fatty acid [LCPUFA, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)] supplementation in clinical cancer therapy. A comprehensive literature search was performed to identify relevant clinical intervention studies conducted through August 2020. Fifty-seven unique cancer trials, assessing EPA and/or DHA supplementation pre- or post-treatment, concomitant with neoadjuvant chemotherapy, radiation or surgery, or in palliative therapy were included. Breast, head and neck, gastrointestinal, gastric, colorectal/rectal, esophageal, leukemia/lymphoma, lung, multiple myeloma and pancreatic cancers were investigated. Across the spectrum of cancers, the evidence suggests that supplementation increased or maintained body weight, increased progression-free and overall survival, improved overall quality of life, resulted in beneficial change in immune parameters and decreased serious adverse events. Taken together, the data support that EPA and/or DHA could be used to improve outcomes important to the patient and disease process. However, before incorporation into treatment can occur, there is a need for randomized clinical trials to determine the dose and type of n-3 LCPUFA intervention required, and expansion of outcomes assessed and improved reporting of outcomes.

Dietary arginine and citrulline supplementation modulates the immune condition and inflammatory response of European seabass. FISH & SHELLFISH IMMUNOLOGY 2020; 106:451-463. [PMID: 32800985 DOI: 10.1016/j.fsi.2020.07.060] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Revised: 07/14/2020] [Accepted: 07/28/2020] [Indexed: 06/11/2023]
Abstract
The present study was designed to determine the modulatory effects of arginine and citrulline dietary supplementation on the immune condition and inflammatory response of European seabass, Dicentrarchus labrax. Four diets were manufactured: a control diet (CTRL) was formulated to meet the indispensable amino acids profile established for seabass. Based on this formulation, three other diets were supplemented with l-arginine at two different levels (0.5% and 1%, ARG1 and ARG2, respectively) and l-citrulline at 0.5% (CIT). Fish were fed these diets for 2 or 4 weeks under controlled conditions. At the end of 4 weeks, fish from all dietary treatments were intraperitoneally-injected with Photobacterium damselae piscicida and sampled after 4, 24 our 48 h. Immune status was characterized by a lymphocyte time-dependent decrease regardless of dietary treatment, whereas peroxidase values dropped in time in fish fed ARG1 and ARG2 and was lower at 4 weeks in fish fed ARG1 than in fish fed CTRL. Up-regulation of several genes was more evident in ARG1-and CIT-fed fish, though pro-inflammatory cytokines were down-regulated by CIT dietary treatment. Following immune stimulation, seabass fed ARG1 showed a decrease in neutrophils and monocytes circulating numbers. On the other hand, expression of 17 selected immune and inflammatory responses genes was barely affected by dietary treatments. Based on the analyzed parameters, results suggest an active role of dietary arginine/citrulline supplementation in modulating immune defences that seem to translate into a suppressed immune repertoire, mostly at the cell response level. The observed changes due to citrulline dietary supplementation were in part similar to those caused by arginine, suggesting that citrulline might have been used by macrophages as an arginine precursor and then engaged in similar immune-impairment leading mechanisms.

Abstract
Immunonutrition is administered to improve the outcome of patients with pancreatic cancer undergoing surgery. However, its effect and mechanism of action remain unclear. Therefore, we conducted this systematic review and meta-analysis to assess its effects on postoperative outcome and the immune system. Randomized controlled trials (RCTs) were identified and data extracted by two reviewers independently from electronic databases from their inception to 31 October 2019. The result was expressed as the risk ratio (RR) for categorical variables and mean difference (MD) for continuous variables with 95% confidence intervals (CIs). Six RCTs published from 1999 and 2016, with a total of 368 patients, were included. The results revealed that immunonutrition significantly decreased the rate of infectious complications (RR = 0.47, 95% CI (0.23, 0.94), p = 0.03) and the length of hospital stay (MD = -1.90, 95% CI (-3.78, -0.02), p = 0.05) by modulating the immune system, especially in preoperative group in subgroup analysis. We therefore recommend that patients with pancreatic cancer undergoing surgery could take the advantage of immunonutrition, especially in the preoperative period.

Abstract
The effects of nutritional support on well-nourished patients have been investigated, but the results were inconsistent among different articles. We performed the meta-analysis to examine the existing evidence. We systematically retrieved articles from PubMed, Web of Science and the Cochrane Library to identify the evidence of nutritional support for well-nourished patients. Methodological quality assessment was assessed based on the Cochrane Handbook and GRADE. Nine randomized controlled trials (RCTs) and one non-RCT with 1400 participants were included in this meta-analysis. Nutritional support, particularly immunonutrition, was associated with a significant reduction in postoperative infectious complications (OR = 0.74, 95% CI: 0.57-0.96), and a decreasing trends in morbidity and the length of the hospital stay (LOS) were observed. However, the mortality rates were comparable between two groups. The quality of evidence was moderate to high. Nutritional support, particularly immunonutrition supplementation, is likely to reduce infectious complications, morbidity and LOS without influencing mortality and may be a safe and preferred choice for well-nourished patients undergoing surgery for cancer. However, additional RCTs are warranted to determine the effects of nutritional support on well-nourished patients.

Abstract
Simple Summary In the current study, we hypothesized that the in ovo injection of L-arginine (L-Arg) at different stages of embryonic development, which would have positive effects on the survival rate, hatching rate, immunoglobulin M (IgM) levels, heat shock proteins (HSPs) such as HSP-47, HSP-60, and HSP-70, and muscle development markers as well: Mainly, myoblast determination protein (myoD) and myogenin in pectoral muscles. As indicated, the in ovo injection of L-Arg resulted in an increased hatch rate and weight, survival rate, higher levels of IgM, and myogenin and MyoD expression in the muscles. At the same time, a decrease in the level of HSP-47, HSP-60, and HSP-70 expressions in the tissues was observed on the 14th day of injection compared to the eighth and 18th day of the injection period. In addition, the in ovo injection of L-Arg decreased the serum glutamate oxaloacetate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) concentration in serum as well micronuclei and nuclear abnormality in the blood on the 14th day of the incubation period. Hence, the 14th day would be a suitable day for the injection of L-Arg to promote the hatching rate and muscle growth of broiler chickens. Abstract The aim of this study was to evaluate the effect of in ovo injection with different ratios of L-arginine (L-Arg) into Ross broiler eggs at three different embryonic developmental stages (eighth day (d), 14th day, and 18th day) on the survival, hatchability, and body weight (BW) of one-day-old hatched chicks. Additionally, we have analyzed the levels of serum glutamate oxaloacetate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT), the protein expression of heat shock proteins (HSPs), and we have also determined micronuclei (MN) and nuclear abnormality (NA). In addition, the genotoxic effect was observed in peripheral blood cells such as the presence of micronuclei and nuclear abnormalities in the experimental groups. The results showed that survival and hatching rates as well as body weight were increased on the 14th day of incubation compared to the eighth and 18th day of incubation at lower concentrations of L-Arg. Moreover, the levels of SGOT and SGPT were also significantly (p < 0.05) increased on the 14th day of incubation at the same concentration (100 μg/μL/egg) of injection. In addition, immunoglobulin (IgM) levels were increased on the 14th day of incubation compared to other days. The protein expressions of HSP-47, HSP-60, and HSP-70 in the liver were significantly down-regulated, whereas the expression of myogenin and myoblast determination protein (MyoD) were significantly up-regulated on the 14th day after incubation when treated with all different doses such as 100 μg, 1000 μg, and 2500 μg/μL/egg, namely 3T1, 3T2, and 3T3, respectively. However, the treatment with low doses of L-Arg down-regulated the expression levels of those proteins on the 14th day of incubation. Histopathology of the liver by hematoxylin and eosin (H&E) staining showed that the majority of liver damage, specifically intracytoplasmic vacuoles, were observed in the 3T1, 3T2, and 3T3 groups. The minimum dose of 100 μg/mL/egg on the 14th day of incubation significantly prevented intracytoplasmic vacuole damages. These results demonstrate that in ovo administration of L-Arg at (100 μg/μL/egg) may be an effective method to increase chick BW, hatch rate, muscle growth-related proteins, and promote the immune response through increasing IgM on the 14th day of the incubation period.

Abstract
This study investigated the antioxidative and anti-inflammatory effect of Phellinus igniarius (PI) on RAW264.7 mouse macrophages. Cell viability was determined using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Measurement of nitric oxide (NO) synthesis was performed using the NO detection. To identify mRNA expressions of cyclooxygenase-2 (COX-2), inducible NO synthase (iNOS), interleukin (IL)-1α, IL-1β, IL-6, and tumor necrosis factor (TNF)-α, real time polymerase chain reaction (PCR) was performed. Assessment of prostaglandin E2 (PGE2) synthesis was performed using the PGE2 immunoassay. Measurement of free radical scavenging activity was performed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The MTT assay revealed that PI exerted no significant cytotoxicity in the RAW 264.7 macrophage cells. From the PGE2 immunoassay and NO detection, PGE2 and NO synthesis were significantly suppressed in the PI treated groups compared to the lipopolysaccharide (LPS) treated groups. Real-time PCR analysis revealed that the mRNA expression of COX-2, iNOS, IL-1α, IL-1β, IL-5, and TNF-α were significantly decreased in the PI treated groups compared to the LPS treated groups. And, PI showed dose-dependent increase in the DPPH radical scavenging activity. In conclusion, PI maybe offer a valuable mode of therapy for the treatment of inflammatory diseases.

Abstract
BACKGROUND Arginine is considered a semi-essential amino acid in healthy adults and the elderly. This amino acid seems to improve the immune system, stimulate cell growth and differentiation, and increase endothelial permeability, among other effects. For those reasons, it has been theorized that arginine supplementation may be used as an adjuvant to conventional cancer therapy treatments. OBJECTIVE This review aims to evaluate the existing knowledge of the scientific community on arginine supplementation in order to improve the efficacy of current cancer treatment. RESULTS Despite the continued efforts of science to improve treatment strategies, cancer remains one of the greatest causes of death on the planet in adults and elderly people. Chemo and radiotherapy are still the most effective treatments but at the cost of significant side effects. CONCLUSION Thus, new therapeutic perspectives have been studied in recent years, to be used in addition to traditional treatments or not, seeking to treat or even cure the various types of cancer with fewer side effects.

Abstract
BACKGROUND Patients with head and neck cancer are often malnourished. Surgery for such cancers is complex and may be undertaken after a course of radiotherapy. As a result, patients may have postoperative complications such as fistulae and wound infections, as well as more generalised infections such as pneumonia. One possible way to enhance recovery, and reduce the incidence of these complications, is by improving nutrition. Nutritional formulas that deliver basic nutrients as well as amino acids (arginine and glutamine), ribonucleic acid (RNA) and/or lipids (omega-3 fatty acids) are known as immunonutrition. OBJECTIVES To assess the effects of immunonutrition treatment, compared to standard feeding, on postoperative recovery in adult patients undergoing elective (non-emergency) surgery for head and neck cancer. SEARCH METHODS The Cochrane ENT Information Specialist searched the ENT Trials Register; Central Register of Controlled Trials (CENTRAL); PubMed; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 14 February 2018. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing immunonutrition given either preoperatively, postoperatively or perioperatively to adult patients (18 years of age or older) undergoing an elective surgical procedure for head and neck cancer, compared with a control group receiving either standard polymeric nutritional supplements or no supplements. DATA COLLECTION AND ANALYSIS We used the standard methodological procedures expected by Cochrane. The primary outcomes were: length of hospital stay (days), wound infection, fistula formation and adverse events/tolerance of feeds, as defined by trial authors. Secondary outcomes were: all-cause mortality and postoperative complications (as defined by trial authors). We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics. MAIN RESULTS We included 19 RCTs (1099 participants). The mean age of participants ranged from 47 to 66 years. Most studies (12/19) had fewer than 25 patients in each treatment group. Most studies (16/19) used immunonutrition formulas containing arginine, but there was variation in the actual products and amounts used, and in the length of intervention postoperatively. Follow-up time for outcome measurement varied considerably across studies, ranging from five days to greater than or equal to 16 months.Primary outcomesWe found no evidence of a difference in the length of hospital stay (mean difference -2.5 days, 95% confidence interval (CI) -5.11 to 0.12; 10 studies, 757 participants; low-quality evidence). Similarly, we found no evidence of an effect of immunonutrition on wound infection (risk ratio (RR) 0.94, 95% CI 0.70 to 1.26; 12 studies, 812 participants; very low-quality evidence). Fistula formation may be reduced with immunonutrition; the absolute risks were 11.3% and 5.4% in the standard care and immunonutrition groups, with a RR of 0.48 (95% CI 0.27 to 0.85; 10 studies, 747 participants; low-quality evidence). We found no evidence of a difference in terms of tolerance of feeds ('adverse events') between treatments (RR 1.33, 95% CI 0.86 to 2.06; 9 studies, 719 participants; very low-quality evidence).Secondary outcomesWe found no evidence of a difference between treatments in all-cause mortality (RR 1.33, 95% CI 0.48 to 3.66; 14 studies, 776 participants; low-quality evidence). Other postoperative complications such as pneumonia and urinary tract infections were not commonly reported. AUTHORS' CONCLUSIONS The risk of postoperative fistula formation may be reduced with immunonutrition, but we found no evidence of an effect of immunonutrition on any of the other outcomes that we assessed. The studies included in this review were generally small or at high risk of bias (or both). We judged the overall quality of the evidence to be low for the outcomes length of hospital stay and all-cause mortality, and very low for wound infection and adverse events. Further research should include larger, better quality studies.

Pharmaconutrition administration on outcomes of elective oncological surgery for gastrointestinal malignancies: is timing everything?-a review of published meta-analyses until the end of 2016. Transl Gastroenterol Hepatol 2018; 3:52. [PMID: 30225386 DOI: 10.21037/tgh.2018.07.12] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2018] [Accepted: 07/30/2018] [Indexed: 01/01/2023] Open
Abstract
The last 25 years have seen an increasing number of publications attesting the benefits of pharmaconutrition in the management of patients undergoing elective oncological gastrointestinal surgery. A number of randomized controlled trials and meta-analyses suggest the use of pharmaconutrition in this group of patients produces superior outcomes to standard nutritional formulations in terms of postoperative infective complications, anastomotic breakdown and length of hospital stay. The use of pharmaconutrition products, therefore, has gained increasing acceptance for use in elective gastrointestinal oncological surgical populations and been incorporated into practice guidelines. However, there remains doubts as to the robustness of such data supporting these recommendation. This is because studies reporting improved outcomes with pharmaconutrition (I) frequently compare this intervention with non-equivalent control groups; (II) do not report on the actual nutritional provision received by study participants; (III) overlook the potential impact of industry funding on research conducted and (IV) do not adopt a multi-disciplinary approach to the research undertaken. For these reasons, a critical re-appraisal of the use and recommendations of pharmaconutrition in this group of patients is urgently warranted to resolve some of the above mentioned issues. The aim of this review was to analyse meta-analyses published until the end of 2016 in this area to highlight the strengths and weakness of the present research and prioritize certain areas which will benefit from future research.

Abstract
Background Head injury is one of the top three diagnosis leading to intensive care unit (ICU) admission in Malaysia. There has been growing interest in using immunonutrition as a mode of modulating the inflammatory response to injury or infection with the aim of improving clinical outcome. The aim of the present study was to evaluate the effect of an immunonutrition on biomarkers (IL-6, glutathione, CRP, total protein and albumin) in traumatic brain injury patients. Methods Thirty six patients with head injury admitted to neurosurgical ICU in University Malaya Medical Centre were recruited for this study, over a 6-month period from July 2014 to January 2015. Patients were randomized to receive either an immunonutrition (Group A) or a standard (Group B) enteral feed. Levels of biomarkers were measured at day 1, 5 and 7 of enteral feeding. Results Patients in Group A showed significant reduction of IL-6 at day 5 (p < 0.001) with concurrent rise in glutathione levels (p = 0.049). Patients in Group A also demonstrated a significant increase of total protein level at the end of the study (day 7). Conclusion These findings indicate the potential of immunonutrition reducing cytokines and increasing antioxidant indices in patients with TBI. However, further studies incorporating patient outcomes are needed to determine its overall clinical benefits. Trial registration National Medical Research Register (NMRR) ID: 14–1430-23,171.

Abstract
Background Multimodal protocols of perioperative care may enhance postoperative recovery. However, limited information is available on preoperative immune and carbohydrate (CHO)-enriched drinks in patients undergoing hip arthroplasty. We aimed to investigate the effect of a multimodal protocol (ACERTO protocol) plus preoperative immune nutrition on the length of stay (LOS) and the postoperative acute phase response of patients undergoing total hip arthroplasty. Methods Thirty-two patients (mean age, 58 years; range, 26–85 years; 16 males) were randomized to receive either the ACERTO protocol (n = 15, ACERTO Group), which consisted of 6 h preoperative fasting for solids, an oral drink (200 mL of 12.5 % maltodextrin) up to 2 h before induction of anesthesia, restricted intravenous fluids (only 1000 mL of crystalloid fluid after surgery) and preoperative immune nutrition (600 mL/day of Impact - Nestlé, Brazil) for five days prior to surgery, or traditional care (n = 17; control group), which consisted of 6–8 h preoperative fasting, intravenous hydration until the 1st postoperative day and no preoperative immune supplementation. The main endpoint was LOS. C-reactive protein (CRP) was the secondary endpoint and was assessed during induction of anesthesia and on postoperative day 2. Results Neither deaths nor postoperative complications occurred. The median LOS was 3 (2–5) days in the ACERTO group and 6 (3–8) days in controls (P <0.01). Postoperative CRP was higher in the control group (P <0.01). Conclusion The ACERTO multimodal protocol of perioperative care plus preoperative immune nutrition may decrease LOS and postoperative CRP levels in total hip arthroplasty.

Abstract
BACKGROUND & AIMS Despite advances in chemotherapeutic agents and surgical approaches for its management, gastrointestinal cancer still accounts for 27% of new cancer cases and 35% of cancer related mortality worldwide. Omega-3 polyunsaturated fatty acids (PUFAs) specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have anti-inflammatory and anticancer activities and are used as immuno-nutrients. METHODS A literature search was conducted to identify primary research reporting on applications of the omega-3 PUFAs in gastrointestinal cancer. RESULTS Reported laboratory studies indicate a clear role for omega-3 PUFAs in preventing cancer development at various stages including cancer cell proliferation, survival, angiogenesis, inflammation and metastasis. In clinical settings, omega-3 PUFAs have been reported to improve the immune response, maintain lean body mass, improve quality of life and improve overall survival in patients with colorectal and pancreatic cancer. In contrast to other GI cancers, there is a strong connection between inflammation and oesophageal cancer. CONCLUSIONS Little work has been done exploring the role for omega-3 PUFAs in oesophageal cancer prevention and management. The authors are conducting a clinical trial investigating the use of parenteral omega-3 PUFAs supplementary to the standard of care (epirubicin, oxaliplatin and capecitabine palliative chemotherapy) in patients with advanced oesophagogastric cancer as a promising new therapeutic approach.

Abstract
Enteral immunonutrition (EIN) has been established to be as a significantly important modality to prevent the postoperative infectious and noninfectious complications, enhance the immunity of host, and eventually improve the prognosis of gastrointestinal (GI) cancer patients undergoing surgery. However, different support routes, which are the optimum option, remain unclear. To evaluate the effects of different EIN support regimes for patients who underwent selective surgery for resectable GI malignancy, a Bayesian network meta-analysis (NMA) of randomized controlled trials (RCTs) was conducted. A search of PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) was electronically searched until the end of December 2014. Moreover, we manually checked reference lists of eligible trials and review and retrieval unpublished literature. RCTs which investigated the comparative effects of EIN versus standard enteral nutrition (EN) or different EIN regimes were included if the clinical outcomes information can be extracted from it. A total of 27 RCTs were incorporated into this study. Pair-wise meta-analyses suggested that preoperative (relative risk [RR], 0.58; 95% confidence interval [CI], 0.43-0.78), postoperative (RR, 0.63; 95% CI, 0.52-0.76), and perioperative EIN methods (RR, 0.46; 95% CI, 0.34-0.62) reduced incidence of postoperative infectious complications compared with standard EN. Moreover, perioperative EIN (RR, 0.65; 95% CI, 0.44-0.95) reduced the incidence of postoperative noninfectious complications, and the postoperative (mean difference [MD], -2.38; 95% CI, -3.4 to -1.31) and perioperative EIN (MD, -2.64; 95% CI, -3.28 to -1.99) also shortened the length of postoperative hospitalization compared with standard EN. NMA found that EIN support effectively improved the clinical outcomes of patients who underwent selective surgery for GI cancer compared with standard EN. Our results suggest EIN support is promising alternative for operation management in comparison with standard EN, and perioperative EIN regime is the optimum option for managing clinical status of patients who underwent selective surgery for GI cancer.

Abstract
BACKGROUND Nanoparticles are small-scale substances (<100 nm) with unique properties. Therefore, nanoparticles pose complex health risk implications. The objective of this study was to detect whether treatment with quercetin (Qur) and/or arginine (Arg) ameliorated nephrotoxicity induced by two different doses of nano zinc oxide (n-ZnO) particles. METHOD ZnO nanoparticles were administered orally in two doses (either 600 mg or 1 g/Kg body weight/day for 5 conscutive days) to Wister albino rats. In order to detect the protective effects of the studied antioxidants against n-ZnO induced nepherotoxicity, different biochemical parameters were investigated. Moreover, histopathological examination of kidney tissue was performed. RESULTS Nano zinc oxide-induced nephrotoxicity was confirmed by the elevation in serum inflammatory markers including: tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6); and C-reactive protein (CRP). Moreover, immunoglobulin (IGg), vascular endothelium growth factor (VEGF), and nitric oxide (NO) were significantly increased in rat serum. Serum urea and creatinine levels were also significantly increased in rats intoxicated with n-ZnO particles compared with the control group. Additionally, a significant decrease in the non-enzymatic antioxidant reduced glutathione (GSH) was shown in kidney tissues and serum glucose levels were increased. These biochemical findings were supported by a histopathological examination of kidney tissues, which showed that in the animals that received a high dose of n-ZnO, numerous kidney glomeruli underwent atrophy and fragmentation. Moreover, the renal tubules showed epithelial desquamation, degeneration and necrosis. Some renal tubules showed casts in their lumina. Severe congestion was also observed in renal interstitium. These effects were dose dependent. Cotreatment of rats with Qur and/or Arg along with n-ZnO significantly improved most of the deviated tested parameters. CONCLUSIONS The data show that Qur has a beneficial effect against n-ZnO oxidative stress and related vascular complications. Also, its combination with Arg proved to be even more effective in ameliorating nano zinc oxide nephrotoxicity.

Abstract
BACKGROUND Immunomodulating diets (IMDs) have been demonstrated to improve immune function and modulate inflammation. However, the clinical benefit of these diets in patients undergoing elective surgery is controversial. The goal of this meta-analysis was to determine the impact of IMDs on the clinical outcomes of high-risk patients undergoing elective surgery. METHODS The review included prospective, controlled, clinical trials that compared the clinical outcome of elective surgical patients who were randomized to receive an IMD or a control enteral diet. Studies were stratified according to the type of IMD and the timing of the initiation of the IMD. Data were abstracted on study design, study size, patient population, and IMD used. The outcomes of interest were the acquisition of new infections, wound complications, length of hospital stay (LOS), and mortality. Meta-analytic techniques were used to analyze the data. RESULTS Twenty-one relevant studies were identified, which included a total of 1918 patients. Immunonutrition significantly reduced the risk of acquired infections, wound complications, and LOS. The mortality rate was 1% in both groups. The treatment effect was similar regardless of the timing of the commencement of the IMD. The benefits of immunonutrition required both arginine and fish oil. CONCLUSIONS An immunomodulating enteral diet containing increased amounts of both arginine and fish oil should be considered in all high-risk patients undergoing major surgery. Although the optimal timing cannot be determined from this study, it is suggested that immunonutrition be initiated preoperatively when feasible.

Abstract
BACKGROUND Enteral immunonutrition (EIN) refers to addition of some specific nutrients in enteral nutrition (EN), which can help to increase the immune function, and reduce the inflammatory reaction and septic complications. This study aimed to determine whether EIN can improve the immune function in multiple trauma patients. METHODS Thirty-two patients with multiple trauma who had been admitted to the general ICU of Changzheng Hospital, Shanghai, from March 2007 to May 2008, were randomly divided into two groups: an enteral immunonutrition group (EIN group, n=16) and an enteral nutrition group (EN group, n=16). EIN suspension (RuiNeng produced by Sino-Swed Co., Ltd) and ordinary nutrition liquid (RuiSu produced by Sino-Swed Co., Ltd) were given to patients of the EIN group and EN group respectively for at least for 14 days. Peripheral blood lymphocyte count (TLC), immunoglobulin (IgG, IgM, IgA), and T-lymphocyte subsets (CD3, CD4, CD8, CD4 / CD8) were detected on the 1st day after grouping, and the 7th day and 14th day after nutritional support. RESULTS TLC, IgG, IgM, IgA, CD4 and CD4/CD8 ratio were significantly higher in the EIN group on the 7th and 14th day than that on the 1st day (P<0.05), and continually increased with a prolonged time of EIN. The parameters of immune function in the EN group on the 7th day didn't change significantly compared with those on the 1st day after grouping; on the 14 th day, TLC, IgG, IgM, IgA, CD4 and CD4/CD8 ratio were significantly higher than those on the 1st day after grouping (P<0.05), but were significantly lower than those in the EIN group on the 14th day (P<0.05). CONCLUSION Compared with the general formula EN, EIN is more helpful for the recovery of humoral and cellular immune function in the early post-multitraumatic phase.

Abstract
AIM: To evaluate the effects of preoperative immunonutrition and other nutrition models on the cellular immunity parameters of patients with gastrointestinal tumors before surgical intervention. In addition, effects on postoperative complications were examined.
METHODS: Patients with gastrointestinal tumors were randomized into 3 groups. The immunonutrition group received a combination of arginine, fatty acids and nucleotides. The second and third group received normal nutrition and standard enteral nutrition, respectively. Nutrition protocols were administered for 7 d prior to the operation. Nutritional parameters, in particular prealbumin levels and lymphocyte subpopulations (CD4+, CD8+, CD16+/56+, and CD69 cells) were evaluated before and after the nutrition protocols. Groups were compared in terms of postoperative complications and duration of hospital stay.
RESULTS: Of the 42 patients who completed the study, 16 received immunonutrition, 13 received normal nutrition and 13 received standard enteral nutrition. prealbumin values were low in every group, but this parameter was improved after the nutritional protocol only in the immunonutrition group (13.64 ± 8.83 vs 15.98 ± 8.66, P = 0.037). Groups were similar in terms of CD4+, CD16+/56, and CD69+ prior to the nutritional protocol; whereas CD8+ was higher in the standard nutrition group compared to the immunonutrition group. After nutritional protocols, none of the groups had an increase in their lymphocyte subpopulations. Also, groups did not differ in terms of postoperative complications and postoperative durations of hospital stay.
CONCLUSION: Preoperative immunonutrition provided a significant increase in prealbumin levels, while it did not significantly alter T lymphocyte subpopulation counts, the rate of postoperative complications and the duration of hospital stay.

Abstract
The effect of docosahexaenoic acid (DHA) on the killing efficacy of imatinib on HL-60 cells expressing the Bcr-Abl protein was investigated. Imatinib is an Abl tyrosine kinase inhibitor used in the treatment of patients with chronic myeloid leukemia. The pre-treatment with DHA for 24 h raised the effect of imatinib at 100 microM concentration only. On the other hand, after 72 h pre-treatment, all concentrations of DHA tested (25, 50 and 100 microM) enhanced the toxic effect of imatinib. These results indicate that long-term pre-treatment with DHA makes Bcr-Abl HL-60 cells more susceptible to the toxic effect of imatinib.

Abstract
BACKGROUND We hypothesized that preoperative and/or postoperative enteral immune-enhanced formulas that are supplemented with arginine, omega-3 fatty acids, and RNA may reduce postoperative complications in patients undergoing esophagectomy for thoracic esophageal squamous cell carcinoma (ESCC). METHODS Forty patients who underwent esophagectomy were divided into three groups: group A (n = 20) received a control enteral diet (Erental) through the jejunostomy after surgery. group B (n = 6) received an enteral diet supplemented with immune-enhancing substrates (Impact) containing arginine, omega-3 fatty acids, and RNA after surgery. group C (n = 14) received the impact before and after surgery. RESULTS Lymphocyte counts in group C on postoperative day (POD) 7 were somewhat higher than that in group A (p = 0.07) and significantly higher than in group B (p = 0.03). Furthermore the incidence of incisional wound infection in group C was significantly lower than that in group A (p = 0.03). Moreover, the duration of postoperative systemic inflammatory response syndrome (SIRS) was significantly shorter in group C than in group A (p < 0.05). CONCLUSIONS This study reveals that the perioperative immune-enhanced formula may be superior to postoperative control enteral formulas in terms of reducing surgical wound infection and postoperative SIRS, which may result in serious postoperative complications for patients who have undergone esophagectomy.

Abstract
OBJECTIVE L-Glutamine, L-arginine, RNA, and omega-3 polyunsaturated fatty acids (PUFAs) have been incorporated into nutritional formulas to improve immunity of patients with gastrointestinal cancer. We therefore examined the individual and net effects of these immunonutrients on four different human colorectal adenocarcinoma cell lines. METHODS LS174T, HT-29, CO112, and Caco-2 cells were exposed to dilutions of 1:50, 1:100, and 1:1000 of a mix or individual components of a mix of 15 g/L of L-glutamine, 16.3 g/L of L-arginine, 1.6 g/L of RNA, and 2.7 g/L of omega-3 PUFAs. Cell growth kinetic was assessed using cell count with a flow cytometer. Cell cycle and apoptosis were evaluated with double fluorescence-activated cell sorter analyses using bromodeoxyuridine labeling index and annexin V staining, respectively. One-way analysis of variance and Student's t tests were used for comparison. RESULTS Evaluation of the cell growth kinetic over an 18-d period showed that the immunonutrient mix stimulated cancer cell growth only when diluted > or =100 times. Individual component evaluation indicated that the cell growth stimulation was mainly due to the presence of L-glutamine and to a lesser extent RNA in the mix. L-Arginine had no effect. At a lower dilution of 1:50, omega-3 PUFA concentrations were sufficient to induce cell cycle arrest and massive cell death in part through apoptosis. CONCLUSION These results suggest that cancer cell growth stimulation by current immunonutrient formulas is unlikely due to predominant cytotoxic effect of omega-3 PUFAs.

Abstract
HIV affects almost all bodily systems, which can lead to recurrent opportunistic infections, weight loss, distribution of weight changes, and death. Malnutrition and wasting, two symptoms that interfere with nutrient availability, accessibility, and metabolism, are associated with higher morbidity and mortality. Nausea, vomiting, swallowing or chewing difficulties, or the response of the body to opportunistic infections or medications that are considered vital to the treatment of the disease may affect nutritional status. A positive nutritional balance may help to improve the immune and other body systems, and delay the progression of the disease, This article reviews the effect of the nutritional status on the physiologic changes in the person who is infected with HIV.

Abstract
OBJECTIVE Patients with head and neck cancer undergoing surgery have a high incidence of postoperative complications. The aim of our study was to investigate whether postoperative nutrition of head and neck cancer patients, using a higher dose of arginine-enhanced diet (17 g/day) than previous studies, could improve nutritional variables as well as clinical outcomes, when compared with a control enteral diet. DESIGN Randomized clinical trial. SETTING Tertiary care. SUBJECTS A population of 72 patients with oral and laryngeal cancer was enrolled. INTERVENTIONS At surgery, patients were randomly allocated to two groups: (a) 35 patients receiving an arginine-enhanced formula with arginine (group I) and (b) 37 patients receiving an isocaloric, isonitrogenous enteral formula (group II). RESULTS No significant intergroup differences in the trend of the three plasma proteins (albumin, transferrin, prealbumin) and lymphocytes were detected. Episodes of diarrhea rate were equal in both groups (22.8% group I and 21.6% group II: NS). The postoperative infections complications were equal in both groups (5.7% group I and 5.4% group II: NS). Fistula (wound complication) was less frequent in enriched nutrition group (2.8% group I and 18.9% group II: P<0.05), whereas wound infection was similar in both groups. The length of postoperative stay was similar in both (27.9+/-21 vs 28.2+/-12 days; NS). CONCLUSIONS At this dose, arginine-enhanced formula improves fistula rates in postoperative head and neck cancer patients without a high rate of diarrhea.

Abstract
AIM To investigate the effects of arginine (Arg)-enriched diets before sepsis and/or Arg-containing total parenteral nutrition (TPN) after sepsis or both on cytokine mRNA expression levels in splenocytes of rats with gut-derived sepsis. METHODS Rats were assigned to four experimental groups. Groups 1 and 2 were fed with a semipurified diet, while groups 3 and 4 had part of the casein replaced by Arg which provided 2% of the total calories. After the rats were fed with these diets for 10 d, sepsis was induced by cecal ligation and puncture (CLP), at the same time an internal jugular vein was cannulated. All rats were maintained on TPN for 3 d. Groups 1 and 3 were infused with conventional TPN, while groups 2 and 4 were supplemented with Arg which provided 2% of the total calories in the TPN solution. All rats were killed 3 d after CLP to examine their splenocyte subpopulation distribution and cytokine expression levels. RESULTS Plasma interleukin (IL)-2, IL-4, tumor necrosis factor-alpha (TNF-alpha) and interferon (IFN-gamma) were not detectable 3 d after CLP. There were no differences in the distributions of CD45Ra(+), CD3(+), CD4(+), and CD8(+) cells in whole blood and splenocytes among the four groups. The splenocyte IL-2 mRNA expression in the Arg-supplemented groups was significantly higher than that in group 1. IL-4 mRNA expression in groups 3 and 4 was significantly higher than that in groups 1 and 2. The mRNA expression of IL-10 and IFN-gamma was significantly higher in group 4 than in the other three groups. There was no difference in TNF-alpha mRNA expression among the four groups. CONCLUSION The influence of Arg on the whole blood and splenic lymphocyte subpopulation distribution is not obvious. However, Arg administration, especially before and after CLP, significantly enhances the mRNA expression levels of Th1 and Th2 cytokines in the spleen of rats with gut-derived sepsis.

Abstract
OBJECTIVE Polyunsaturated fatty acid supplementation may produce beneficial effects after surgery. We investigated the influence of preoperative administration of a supplement rich in arginine, omega-3 fatty acids, and RNA, Impact (Japan), on inflammatory and immune responses in patients undergoing major surgery for cancer. METHODS Patients in the supplement group (n = 12) received 1 L/d of Impact (Japan) for 5 d before surgery, and those in the control group (n = 14) received an ordinary diet without Impact (Japan) before surgery. Plasma levels of omega-3 and omega-6 fatty acids, thromboxane B(2), prostaglandin E(2), inflammatory markers, nutritional markers, cytokines, and cytokine receptors were obtained 5 d before the operation at the starting point of supplementation in the supplement group. Samples were collected on postoperative days (PODs) 0, 1, 3, and 7. RESULTS After taking the supplement, significant increases in omega-3 fatty acids and rapid turnover proteins were found the day after ending supplementation (POD-0), whereas thromboxane B(2) levels and the ratio of omega-6 fatty acids to omega-3 fatty acids were significantly lower than before supplementation (P < 0.001). On POD-0 only, inflammatory markers and cytokine receptors in the supplement group showed low levels in comparison with the control group (P < 0.05). On POD-1 and POD-3, remarkable decreases in polymorphonuclear leukocyte-elastase and interleukin-8 in the supplement group were observed. CONCLUSION Our findings suggest that oral administration of a supplement rich in omega-3 fatty acids for 5 d before surgery may improve not only preoperative nutritional status but also preoperative and postoperative inflammatory and immune responses in patients who have cancer.

Abstract
OBJECTIVE To compare the effect of early enteral feeding using immune-enhancing (IE) vs. non-immune-enhancing (NIE) formulas on cytokines in children with septic shock. DESIGN AND SETTING A single-center, randomized, blinded controlled trial in a pediatric intensive care unit of a university hospital. PATIENTS We randomized 38 patients with septic shock to either IE or NIE. Feedings were advanced to a target volume of energy intake equal to 1/2, 1, 5/4, 6/4, and 6/4 of the predicted basal metabolic rate on days 1-5, respectively. MEASUREMENTS AND RESULTS Interleukins (IL) 1beta, 6, and 8, tumor necrosis factor alpha, C-reactive protein, Pediatric Risk of Mortality (PRISM) score, survival, secondary infections, length of stay, and mechanical ventilation were compared within and between the two groups. Actual mean energy and protein intakes did not differ between the two groups and the caloric-protein balance was not correlated to cytokine levels. On day 5 IL-6 levels were significantly lower (11.8+/-2.4 vs. 38.3+/-3.6) and IL-8 significantly higher in the IE than in the NIE group (65.4+/-17 vs. 21+/-2.5). After 5 days of nutritional support a significant decrease in IL-6 levels was recorded only in group IE (mean of paired differences 39.4+/-3 pg/ml). In multivariate regression analysis the variation in cytokines was independently correlated only to PRISM (R(2)=-0.50), but pediatric intensive care unit outcome endpoints did not differ between the two groups. CONCLUSIONS Early IE nutrition may modulate cytokines in children with septic shock, but there is no evidence that this immunomodulation has any impact on short-term outcome.

Abstract
PURPOSE OF REVIEW This review reports recent findings on lipid use in artificial nutrition in patients with acute respiratory failure or severe sepsis or undergoing major surgery. It examines current knowledge of fatty acid safety, biologic effects, and the impact on patients' morbidity and mortality. The newly emerging area of genotypic influence and timing of immunonutrition is also discussed. RECENT FINDINGS In acute respiratory distress syndrome, the debate concerning the use of long-chain fatty acids as opposed to physical mixtures of medium- and long-chain fatty acids, specifically regarding their effects on gas exchange and pulmonary hemodynamics, still remains unresolved. By contrast, providing fish oil fatty acids (mainly eicosapentaenoic and docosahexaenoic acids) and/or gamma-linolenic acid, seems to decrease harmful excessive inflammatory/immune activation and to improve clinical outcome. Similar effects, although not conclusively demonstrated, have been reported for n-3 fatty acid-enriched lipid emulsions in patients with sepsis. Few recent studies examined the impact of n-3 fatty acid-enriched enteral formulas on patients undergoing major surgery. Most studies focused on intravenous fish oil and suggest beneficial effects both on inflammatory/immune parameters and patient outcome. Studies suggest that lipid use in critically ill patients may be improved by increased knowledge of genetic determinants of severity of injury and response to therapeutic agents as well as by the development of tools that allow better timing of immunonutritional intervention. SUMMARY Overall, lipids, in particular n-3 fatty acids, emerge as powerful nutrients with pharmacologic properties potentially improving prognosis in critically ill patients. However, heterogeneity in study design makes the interpretation of available studies difficult. Consequently, larger prospective, randomized, double-blind trials with comparable methodologies are necessary for detailed evaluation of the pharmacologic impact of lipids. In addition, a better knowledge of the influence of genotypic variation and postinjury inflammatory/immune temporal patterns may improve our current therapeutic use of various fatty acids.

Abstract
The aim of this study was to determine the effect of L-arginine on Porphyromonas gingivalis-induced phagocytosis by RAW264.7 cells. The cells were pretreated with L-arginine or D-arginine prior to incubation with either unopsonized or opsonized P. gingivalis. In other experiments, the cells were pretreated with L-arginine and various concentrations of NMLA (N(G)-monomethyl-L-arginine) prior to incubation with the bacteria. The phagocytosis was microscopically assessed and determined by the phagocytic index. The results showed that L-arginine, but not D-arginine enhances the ability of RAW264.7 cells to engulf the bacteria. The upregulatory effect of L-arginine on P. gingivalis-induced phagocytosis was abolished by NMLA. The results of the present study suggest that L-arginine may upregulate the P. gingivalis-induced phagocytic activity of RAW264.7 cells, perhaps, via modulation of nitric oxide synthase.

Abstract
AIM: To study the treatment of the replication-competent adenovirus-mediated transfer of interleukin-12 gene in the mouse transplanted with gastric cancer in vivo, and to explore the new therapeutic approach of gastric cancer.
METHODS: The efficacy of CNHK200-mIL-12, ONYX-015, Ad-mIL-12 was tested in nude mice and 615 mice with subcutaneous human SGC-7901 and MFC 615 mice carcinomas. The immunological mechanism in xenografts gastric tumor of mice was further analyzed.
RESULTS: The replication-competent adenovirus-mediated transfer of interleukin-12 gene slowed down the tumor progress. This might be caused by the proliferation of the replication-competent adenovirus. Ad-mIL-12 had little effect on the transplanted tumor in nude mice. While 615 mice bearing MFC gastric cancer presented the best anticancer effects. Administration of Ad-mIL-12 was showed to delay the growth of transplanted MFC tumor markedly(P < 0.001), and mediate complete regression of 3/10 established tumor. In the setting of CNHK200-mIL-12, the regression ratio was 4/10. Significantly prolonged survival was observed in both Ad-mIL-12 and CNHK200-mIL-12 experimental groups of MFC gastric tumor bearing mice. The analysis of the immunological mechanism in xenografts gastric tumor of mice 615 showed that the expression of IL-12 by CNHK200-mIL-12 and Ad-mIL-12 could greatly stimulate the immune response against the transplanted gastric tumor. It was found that these therapies could enhance the natural killer cell activity and specific cytotoxic T cell activity. The CD4+ and CD8+ T cell infiltrated into the tumor more significantly than that in the group of ONYX-015 and control (P < 0.001).
CONCLUSION: The replication-competent adenovirus can specifically replicate in tumor cells and kill the tumor cells. IL-12 is an effective cytokine stimulating anticancer immune responses. When combined, it is complementary resulting in a significantly improved treatment outcome.

Abstract
BACKGROUND Experimental and clinical studies have brought evidence that surgical trauma markedly affects the immune system, including both the specific and the non-specific immune response. MATERIALS AND METHODS This report reviews the present knowledge on the mechanisms of surgical trauma-induced immune dysfunction and outlines experimental and clinical approaches to find effective treatment strategies. RESULTS Major surgical trauma induces an early hyperinflammatory response, which is characterized by (1) pro-inflammatory tumour necrosis factor alpha (TNF), interleukin (IL)-1, and IL-6 cytokine release and (2) neutrophil activation and microvascular adherence, as well as (3) uncontrolled polymorphonuclear (PMN) and macrophage oxidative burst. The massive and continuous IL-6 release induces an acute phase response, but, more importantly, also accounts for the up-regulation of major anti-inflammatory mediators, such as prostaglandin (PG) E2, IL-10 and transforming growth factor (TGF)-ss. This results in surgical, trauma-induced, immunosuppression, as indicated by (1) monocyte deactivation, reflected by the lack of monocytic TNF- production upon lipopolysaccharide (LPS) stimulation, and (2) a shift of the Th1/Th2 ratio towards a Th2-dominated cytokine pattern. The imbalance between pro-inflammatory and anti-inflammatory cytokines and immuno-competent cells determines the phenotype of disease and should help the physician to compose the therapeutic strategy. In fact, recent clinical studies have shown that both the initial uncontrolled hyperinflammation and the continued cell-mediated immunosuppression represent primary targets to counteract post-surgery immune dysfunction. The balance between inflammatory and anti-inflammatory forces may be restored by interferon gamma (IFN-gamma) to counteract monocyte deactivation; the anti-inflammatory PGE2 may be inhibited by indomethacin to attenuate immunosuppression; or the initial hyperinflammation may be targeted by administration of anti-inflammatory substances, such as granulocyte colony-stimulating factor (G-CSF), hydoxyethyl starch, or pentoxifylline. CONCLUSIONS When drawing up the therapeutic regimen the physician should not consider hyperinflammation versus immunosuppression, but hyperinflammation and immunosuppression, aiming at restoring an appropriate mediator- and immune cell-associated balance.

Abstract
AIM: To explore the apoptosis-inducing effects of extrinsic BAK gene transfer and its over-expression on gastric cancer cells and its molecular mechanisms.
METHODS: The eukaryotic expression for BAK gene was constructed and transferred into gastric cancer MKN-45 cell line. After being transferred for 1 to 5 d, cellular BAK gene expression was detected by RT-PCR and Western blotting methods. The growth activities of cancer cells were detected by cell count and MTT colorimetry. Cell cycle changes were assayed by flow cytometry. Cellular apoptosis was assayed by electronic microscopy and in situ terminally labeled transferase technique (TUNEL). Cellular caspase-3 activities were observed by colorimetric method.
RESULTS: After being transferred for 1 to 5 d, cellular BAK mRNA and protein expression levels were significantly increased (P < 0.01). In vitro growth of gastric cancer cells was inhibited by 11.6-35.3% (P < 0.01). The cellular proliferation activities were decreased by 10.2-32.4% (P < 0.01), with cell cycle being blocked at G0/G1 phase. Partial cancer cells presented the characteristic morphological changes of apoptosis, with the apoptotic rates being 21.4% (P < 0.01). The cellular caspase-3 activities were enhanced by 4.45 times (P < 0.01).
CONCLUSION: Transfection of extrinsic BAK gene, resulting in its over-expression, can significantly induce apoptosis of gastric cancer MKN-45 cells through activating caspase-3, which is a potential strategy for gene therapy of gastric cancer.

Abstract
OBJECTIVE Patients with head and neck cancer undergoing surgery have a high incidence of postoperative complications. The aim of our study was to investigate whether postoperative nutrition of head and neck cancer patients using an arginine-enhanced formula could improve nutritional variables as well as clinical outcomes. DESIGN Randomized clinical trial. SETTING Tertiary care. SUBJECTS A population of 90 patients with oral and laryngeal cancer was enrolled. INTERVENTIONS At surgery, patients were randomly allocated to two groups: (a) patients receiving an arginine-enhanced formula with arginine and fiber (group I) and (b) patients receiving an isocaloric, isonitrogenous formula with fiber enteral formula (group II). RESULTS No significant intergroup differences in the trend of the three plasma proteins (albumin, transferrin, prealbumin) and lymphocytes were detected. Gastrointestinal tolerance (diarrhea) was better in group II than I (40% group I and 13% group II: P<0.05). The postoperative complications due to infections were similar in both groups (4% group I and 9% group II: ns). Fistula (wound complication) was less frequent in the enriched nutrition group (5% group I and 11% group II: P<0.05); wound infection was similar in both groups. The length of postoperative stay was better in group I than II (25.8+/-15 days vs 35+/-24.6 days; P<0.05). CONCLUSIONS In conclusion, arginine-enhanced formula improves fistula rates in postoperative head and neck cancer patients and decreases length of stay.

Abstract
Lipids used in nutritional support of surgical or critically ill patients have been based on soybean oil, which is rich in the n-6 fatty acid linoleic acid (18:2n-6). Linoleic acid is the precursor of arachidonic acid (20:4n-6). In turn, arachidonic acid in cell membrane phospholipids is the substrate for the synthesis of a range of biologically active compounds (eicosanoids) including prostaglandins, thromboxanes, and leukotrienes. These compounds can act as mediators in their own right and can also act as regulators of other processes, such as platelet aggregation, blood clotting, smooth muscle contraction, leukocyte chemotaxis, inflammatory cytokine production, and immune function. There is a view that an excess of n-6 fatty acids should be avoided since this could contribute to a state where physiological processes become dysregulated. One alternative is the use of fish oil. The rationale of this latter approach is that fish oil contains long chain n-3 fatty acids, such as eicosapentaenoic acid. When fish oil is provided, eicosapentaenoic acid is incorporated into cell membrane phospholipids, partly at the expense of arachidonic acid. Thus, there is less arachidonic acid available for eicosanoid synthesis. Hence, fish oil decreases production of prostaglandins like PGE2 and of leukotrienes like LTB4. Thus, n-3 fatty acids can potentially reduce platelet aggregation, blood clotting, smooth muscle contraction, and leukocyte chemotaxis, and can modulate inflammatory cytokine production and immune function. These effects have been demonstrated in cell culture, animal feeding and healthy volunteer studies. Fish oil decreases the host metabolic response and improves survival to endotoxin in laboratory animals. Recently clinical studies performed in various patient groups have indicated benefit from this approach.

Abstract
The addition of immune-modulating nutrients to enteral formulas has been examined in clinical trials and meta-analyses. Enhancing immunity through diet is generally done by adding n-3 fatty acids, arginine, and nucleotides to an otherwise nutritionally complete formula. Despite flaws in many studies, a consistent trend to reduced infectious complications has been seen with immunonutrition, especially in patients undergoing surgery for upper gastrointestinal cancer or trauma. In critical care populations, however, the results have been mixed. In this review, we analyze these studies and focus on select clinical points that may explain the variation. One common flaw has been a failure to deliver an adequate nutrition volume. Few patients, especially in the earliest studies, received even close to goal feeding. A minimum quantity of immunonutrition may be required for effective reduction in infections. When feeding volumes are low, immunonutrition is usually not better than an isonitrogenous control. In more recent studies, practitioners have been increasingly aggressive with enteral feeding, and this has been reflected in improved outcomes from immunonutrition. Early delivery of immunonutrition (preoperatively in surgical patients with cancer) might be particularly beneficial. Another consideration is illness severity: we discuss evidence that the use of immunonutrition in moderate illness is more likely to be helpful, whereas severe sepsis is probably beyond the reach of any nutritional intervention, and mild illness is more likely to improve irrespective of feeding. If future trials can consider these vital points, level 1 recommendations in favor of immunonutrition might be justified, although presently such evidence is lacking for most clinical indications.

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
The n-3 polyunsaturated fatty acids (PUFA) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are found in high proportions in oily fish and fish oils. The n-3 PUFA are structurally and functionally distinct from the n-6 PUFA. Typically, human inflammatory cells contain high proportions of the n-6 PUFA arachidonic acid and low proportions of n-3 PUFA. The significance of this difference is that arachidonic acid is the precursor of 2-series prostaglandins and 4-series leukotrienes, which are highly-active mediators of inflammation. Feeding fish oil results in partial replacement of arachidonic acid in inflammatory cell membranes by EPA. This change leads to decreased production of arachidonic acid-derived mediators. This response alone is a potentially beneficial anti-inflammatory effect of n-3 PUFA. However, n-3 PUFA have a number of other effects which might occur downstream of altered eicosanoid production or might be independent of this activity. For example, animal and human studies have shown that dietary fish oil results in suppressed production of pro-inflammatory cytokines and can decrease adhesion molecule expression. These effects occur at the level of altered gene expression. This action might come about through antagonism of the effects of arachidonic acid-derived mediators or through more direct actions on the intracellular signalling pathways which lead to activation of transcription factors such as nuclear factor kappa B (NFB). Recent studies have shown that n-3 PUFA can down regulate the activity of the nuclear transcription factor NFB. Fish oil feeding has been shown to ameliorate the symptoms in some animal models of chronic inflammatory disease and to protect against the effects of endotoxin and similar inflammatory challenges. Clinical studies have reported that oral fish oil supplementation has beneficial effects in rheumatoid arthritis and among some patients with asthma, supporting the idea that the n-3 PUFA in fish oil are anti-inflammatory. There are indications that inclusion of n-3 PUFA in enteral and parenteral formulas might be beneficial to patients in intensive care or post-surgery.

Abstract
OBJECTIVE Patients with head and neck cancer undergoing surgery have a high incidence of postoperative complications. The aim of our study was to investigate whether postoperative nutrition of head and neck cancer patients, using an arginine-enriched diet, could improve nutritional variables as well as clinical outcomes. DESIGN Randomized clinical trial. SETTING Tertiary care. SUBJECTS A population of 47 patients with oral and laryngeal cancer were enrolled. INTERVENTIONS At surgery patients were randomly allocated to two groups: (a) patients receiving an enteral diet supplemented with arginine and fiber (group I); (b) patients receiving an isocaloric, isonitrogenous enteral formula (group II). RESULTS No significant intergroup differences in the trend of the three plasma proteins and lymphocytes were detected. Gastrointestinal tolerance (diarrhea) of both formulas was good (17.4% group I and 8.3% group II; NS). During the 3 months after hospital discharge five patients died; no differences were detected between groups (13% group I and 8.3% group II; NS). The incidences postoperative infection complications were similar (nine patients) in both groups (21.7% group I and 16.7% group II; NS). Fistula were less frequent in enriched nutrition group (0% group I and 20.8% group II; P<0.05); wound infection was more frequent in group II, but without statistical difference (4.3% group I and 12.5% group II; NS). The length of postoperative stay was 22.8+/-11.8 days in the enriched group and 31.2+/-19.1 days in the control group (P=0.07). CONCLUSIONS In conclusion, enriched formula improves local wound complications in postoperative head and neck cancer patients. Our results suggest that these patients could benefit from an immunonutrient-enhanced enteral formula.

Abstract
AIM: To study the anti-inflammatory effects of cholecystokinin-octapeptide (CCK-8) on lipopolysaccharide (LPS)-induced endotoxic shock (ES) and further investigate its signal transduction pathways involving p38 mitogen-activated protein kinase (MAPK) and IκB-α.
METHODS: Eighty-four rats were divided randomly into four groups: LPS (8 mg·kg-1, iv) induced ES; CCK-8 (40 μg·kg-1, iv) pretreatment 10 min before LPS (8 mg·kg-1); CCK-8 (40 μg·kg-1, iv) or normal saline (control) groups. The inflammatory changes of lung and spleen, phagocytic function of alveolar macrophage, quantification of inflammatory cells in bronchoalveolar lavage (BAL) were investigated in rats by using hematoxylin and eosin (HE) staining, phagocytosis of Candida albicans and differential cell counting. Nitric oxide (NO) production in serum, lung and spleen was measured with the Griess reaction. The mechanism involving p38 MAPK and IκB-α signal pathways was investigated by Western blot.
RESULTS: Inflammatory changes of lung and spleen induced by LPS were alleviated by CCK-8, the increase of NO induced by LPS in serum, lung and spleen was significantly inhibited and the neutrophil infiltration in BAL was significantly reduced by CCK-8. The number of neutrophils was (52 ± 10) × 106 cells•L-1 in LPS group, while it decreased to (18 ± 4) × 106 cells•L-1 in CCK-8+LPS (P < 0.01). The phagocytic rate of CCK-8 group increased to (62.49 ± 9.49)%, compared with control group (48.16 ± 14.20)%, P < 0.05. The phagocytosis rate was (85.14 ± 4.64)% in LPS group, which reduced to (59.33 ± 3.14)% in CCK-8+LPS group (P < 0.01). The results of phagocytosis indexes showed similar changes. CCK-8 may play an important role in increasing the expression of p38 MAPK and decreasing the degradation of IκB-α in lung and spleen of ES rats.
CONCLUSION: CCK-8 can result in anti-inflammatory effects, which may be related to activation of p38 MAPK and inhibition on the degradation of IκB-α.
