Abstract
INTRODUCTION Although a variety of nutritional indices have been found to be valuable in predicting patient outcome when used alone, there is no consensus on the best method for assessing the nutritional status of hospitalized patients. Therefore, the aim of this study was to assess the nutritional status of a cohort of patients who underwent major elective surgery using the Nutritional Risk Index (NRI), Maastricht Index (MI), Subjective Global Assessment (SGA), and Mini Nutritional Assessment (MNA) to determine the best possible nutrition screening system in surgical practice. METHODS The study population consisted of 460 patients who underwent major elective surgery between December 1999 and March 2002. Each patient had a complete set of the three nutritional assessment techniques (NRI, MI, SGA); in addition, the MNA was performed in patients older than 59 years of age. One of the coauthors who was unaware of the nutritional assessments assessed the patients for postoperative morbidity and mortality. Complications were classified as major or minor and as infectious or noninfectious. To assess the predictive value of the assessment techniques, likelihood ratios were calculated for the various strata of each method. The odds ratio and receiver operating characteristic (ROC) curves were also calculated to describe and compare the diagnostic value of each of the four nutrition indices. RESULTS Twenty patients died during the study period. No complications occurred in 329 of the 460 patients; 42 patients suffered from two or more complications. The frequency of malnutrition was found to be 58.3%, 63.5%, and 67.4% as assessed by the SGA, NRI, and MI, respectively. Morbidity rates, especially severe infectious and noninfectious complications, were significantly higher in malnourished patients in all nutritional indices. The likelihood ratio was well correlated with the risk categories of every nutritional index. The area under the ROC curves revealed that each scoring system proved to be significantly powerful in predicting the morbidity (infectious and noninfectious severe morbidity) and mortality. However, no differences were detected among the nutritional indices in 460 patients. The odds ratio for morbidity between the well nourished and malnourished patients was 3.09 [95% confidence interval (CI), 1.96-4.88], 3.47 (95% CI, 2.12-5.68), 2.30 (95% CI, 1.43-3.71), and 2.81 (95% CI, 0.79-9.95) for the SGA, NRI, MI, and MNA, respectively. All indices except the MNA were significantly predictive for morbidity. The odds ratios were not statistically different among the indices. CONCLUSIONS Our findings revealed that all nutritional assessment techniques can be safely applied to the clinical setting with no significant difference in predictive value. We therefore strongly recommend the use of any of these techniques to improve the outcome of surgical care. Meanwhile, further investigations are needed, and much effort must be given to find the best method for assessing nutritional status.

Abstract
Patients with cirrhosis develop metabolic derangements of protein, carbohydrate, and lipid metabolism. Malnutrition is commonplace and is associated with morbidity and mortality. Specific nutrient deficiencies may occur and enteral or parenteral nutritional support may improve outcome in appropriately selected patients. Parenteral nutrition itself has been associated with hepatic dysfunction, although the preponderance of evidence suggests that hepatic dysfunction is more a function of the underlying disorder and malabsorption. Intravenously infused organic nutrients may be metabolized differently than the same nutrient consumed enterally. The pathophysiology of total parenteral nutrition-associated liver disease is discussed as well as potential management options.

Abstract
Malnutrition is highly prevalent among patients with chronic liver disease and is nearly universal among patients awaiting liver transplantation. Malnutrition in patients with cirrhosis leads to increased morbidity and mortality rates. Furthermore, patients who are severely malnourished before transplant surgery have a higher rate of complications and a decreased overall survival rate after liver transplantation. In light of the high incidence of malnutrition among patients with chronic liver disease and the complications that result from malnutrition in these patients, it is essential to assess the nutritional status of all patients with liver disease, and to initiate treatment as indicated. This review addresses the etiologies of malnutrition, methods used to assess nutritional status, and appropriate treatment strategies.

Abstract
AIM: To investigate the association between malnutrition and quality of life in patients with benign gastrointestinal disease.
METHODS: Two hundred patients (104 wellnourished and 96 malnourished) were assessed according to the Subjective Global Assessment, anthropometric measurements and bioelectrical impedance analysis. Quality of life was determined with the validated Medical Outcomes Study 36-item Short-Form General Health Survey (SF 36). Muscle function was assessed by hand grip strength and peak flow.
RESULTS: Body mass index, body cell mass, arm muscle area and hand grip strength were significantly lower in the malnourished patients. Quality of life was generally lower when compared to norm values. Seven out of eight quality of life scales (excluding bodily pain) were significantly reduced in the malnourished patients. Comparing patients with liver cirrhosis and inflammatory bowel disease (IBD), patients with IBD experienced significantly lower values in the perception of bodily pain,social functioning and mental health. Malnourished liver cirrhotics suffered reductions in more scales (six out of eight) than malnourished IBD patients did (four out of eight).
CONCLUSION: Quality of life is generally low in benign gastrointestinal disease and is further reduced in patients who are classified as malnourished. It appears that liver cirrhosis patients experience a higher quality of life than IBD patients do, but the impact of malnutrition seems to be greater in liver cirrhosis than in IBD.

Abstract
Enteral nutrition (EN) by means of oral nutritional supplements (ONS) and tube feeding (TF) offers the possibility to increase or to insure nutrient intake in case of insufficient oral food intake. The present guideline is intended to give evidence-based recommendations for the use of ONS and TF in patients with liver disease (LD). It was developed by an interdisciplinary expert group in accordance with officially accepted standards and is based on all relevant publications since 1985. The guideline was discussed and accepted in a consensus conference. EN by means of ONS is recommended for patients with chronic LD in whom undernutrition is very common. ONS improve nutritional status and survival in severely malnourished patients with alcoholic hepatitis. In patients with cirrhosis, TF improves nutritional status and liver function, reduces the rate of complications and prolongs survival. TF commenced early after liver transplantation can reduce complication rate and cost and is preferable to parenteral nutrition. In acute liver failure TF is feasible and used in the majority of patients.

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
The metabolic changes compounded by anorexia associated with chronic liver disease adversely affect growth in children. In many cases, this requires the administration of artificial nutritional support. It is important in this group of patients that those who are becoming nutritionally depleted are identified quickly and in those receiving artificial nutritional support, the effectiveness is monitored. The current review is an examination of methods available to assess nutritional status. These include anthropometry, methods available in the laboratory and a selection of less commonly used methods undergoing evaluation at research level. A brief discussion accompanies each technique, outlining the limitations of its use in children with chronic liver disease. The review concludes with an outline of how nutritional status should be assessed in this group of children, and suggests further research.

Abstract
A model that can accurately predict post-liver transplant mortality would be useful for clinical decision making, would help to provide patients with prognostic information, and would facilitate fair comparisons of surgical performance between transplant units. A systematic review of the literature was carried out to assess the quality of the studies that developed and validated prognostic models for mortality after liver transplantation and to validate existing models in a large data set of patients transplanted in the United Kingdom (UK) and Ireland between March 1994 and September 2003. Five prognostic model papers were identified. The quality of the development and validation of all prognostic models was suboptimal according to an explicit assessment tool of the internal, external, and statistical validity, model evaluation, and practicality. The discriminatory ability of the identified models in the UK and Ireland data set was poor (area under the receiver operating characteristic curve always smaller than 0.7 for adult populations). Due to the poor quality of the reporting, the methodology used for the development of the model could not always be determined. In conclusion, these findings demonstrate that currently available prognostic models of mortality after liver transplantation can have only a limited role in clinical practice, audit, and research.

Abstract
BACKGROUND Muscle dysfunction is a common finding in malnourished patients and is associated with poor outcome. We investigated whether the Subjective Global Assessment (SGA) is a valuable tool for identifying malnutrition-related muscle dysfunction. METHODS Two hundred eighty seven consecutive patients were assessed on admission to hospital according to the SGA, anthropometric measurements, and to the results of bioelectrical impedance analysis. The SGA was used as the main criterion for the classification of malnutrition. Muscle function was assessed by handgrip strength. RESULTS Maximal voluntary handgrip strength was significantly lower in malnourished than in well-nourished male and female patients (45.22 (13.51-67.7)kg versus 30.82(11-48) kg in men; 23.81 (5.60-56.5) kg versus 18.5 (5.90-48.8) kg in women). Handgrip strength tended to decline with age. Handgrip strength was positively correlated to body cell mass (BCM) (r=0.72, P<0.001 in men and: r=0.56, P<0.001 in women) and to body mass index (r=0.271, P=0.03 in men and r=0.183, P=0.02 in women). BCM was identified as a powerful contributor to the variation in handgrip strength (delta r2=0.645, P<0.001). CONCLUSION The SGA appears to be a reliable bedside assessment tool for malnutrition and malnutrition-related dysfunction. Patients classified malnourished according to the SGA have an impaired functional status. Every effort should be made to provide both nutritional and physical therapy in order to improve the patients' outcome.

Abstract
Patients undergoing liver transplantation (LT) often experience dietary restrictions that may influence their nutritional status. With the objective of comparing the status of liver transplant patients pre- versus in the early and late postoperative periods, a retrospective study evaluated 33 adults (63.6% men and 36.4% women) mean age 47 years for body mass index (BMI), current body weight/ideal body weight (%CBW/IBW), current body weight/usual body weight (%CBW/UBW), adequacy of tricipital skin fold (%TSF), generalized adipose reserve (%F), adequacy of mid-upper arm muscle circumference (%MMC), and serum albumin. The elapsed time between nutritional evaluation and LT was 446 days for the pre-LT group, 31 for the early post-LT group, and 244 for the late post-LT group; 30.3% were Child C and 63.6% B in the pre-LT phase. The median value to %TST in pre-LT, early LT, and late LT were 91.7%, 70.8%, and 78.0%, respectively. The analysis of mean value of %F was 25.9% in the pretransplant, 23.3% in early postoperative, and 25.3% in late postoperative stages %MMC was 85.5% for pretransplant patients, it was 86.6% in the early versus 89.9% in the late stages. While BMI was 24.9 kg/m(2) in the preoperative 22.9 kg/m(2) in early, and 24.2 kg/m(2) in late phases. Similarly, concerning %CBW/UBW the mean values were 96.2% in the preoperative group, 64.1% in early, and 101.9% in late groups. The %CBW/IBW mean values were 113.9% in the pre- versus 104.6% in the early and 111.2% in the late periods. The values of serum albumin and %CBW/UBW were statistically different for Child B,C as well as when the patients were not classified by the Child criteria. There was a deterioration in status from pretransplant period to early postoperative with improvement in the late period.

Abstract
BACKGROUND Malnutrition is frequent in cirrhotic patients, and its assessment is difficult. Functional assessment through a dynamometer is a simple method and could minimize these drawbacks. Harris-Benedict prediction formulae estimates the resting energy expenditure but has not been validated for this population. One alternative is the use of indirect calorimetry. AIM To assess nutritional status in cirrhotic patients and estimates the resting energy expenditure through indirect calorimetry and compares it to Harris-Benedict. PATIENTS AND METHODS Thirty four adult hepatitis C cirrhotic outpatients were studied, classified by Child-Pugh and model of end-stage liver disease score. The resting energy expenditure was predicted through Harris-Benedict and measured by indirect calorimetry. Nutritional assessment was done through anthropometry, subjective global assessment, hand-grip strength and a 3-day recall. RESULTS Fifteen (44.2%) were Child-Pug A, 12 (35.3%) B and 7 (20.6%) C, and 33 (97.1%) had model of end-stage liver disease scores less than 20. The resting energy expenditure predicted was higher than the measured (Harris-Benedict 1404.5 +/- 150.3 kcal; indirect calorimetry 1059.9 +/- 309.6 kcal). The prevalence of malnutrition varied between methods (body mass index, muscle arm circumference, subjective global assessment, triceps skinfold thickness and hand-grip strength: 0; 5.9; 17.6; 35.3 and 79.4%, accordingly). Calories and proteins intake were 80% and 85% of recommended amounts and there was inadequate intake of calcium, magnesium, iron and zinc. CONCLUSION Malnutrition was frequent and hand-grip strength seemed to be the most sensitive method for its diagnosis. Calories and protein intakes were inadequate. Considering that the predicted resting energy expenditure was higher than the measured one and the need to offer higher caloric intake, the use of the predicting equation may replace indirect calorimetry.

Abstract
BACKGROUND Malnutrition is common in patients with end-stage liver disease considered for transplantation, but it is unclear whether this affects the outcome after transplantation. AIM.: To determine whether the severity of malnutrition in liver transplant candidates affects outcome after transplantation. METHODS We did a prospective study of 61 patients with chronic liver disease accepted for transplantation. FINDINGS The Child-Pugh and Model for End-Stage Liver Disease (MELD) score correlated significantly but weakly with the mid-arm circumference (MAC) (rho=-0.34 and -0.31, P=0.015 and 0.025, respectively) but not with hand-grip strength, triceps skin-fold thickness (TSFT), or mid-arm muscle circumference. The Child-Pugh score but not the MELD was significantly associated with intensive therapy unit stay but not eventual outcome; there was a weak but statistically significant correlation between death and MAC (rho=+0.29, P=0.04) and TSFT (rho=+0.25, P=0.02). CONCLUSIONS These findings suggest that nutritional parameters and markers of disease severity do not correlate well with outcomes after transplantation.

Abstract
RACIONAL: O transplante hepático é o tratamento de escolha para várias doenças hepáticas terminais. A desnutrição nesta população é freqüente. O uso de nutrição enteral precoce não é rotina nos grupos de transplante. OBJETIVO: Relatar a experiência do uso de nutrição enteral precoce em indivíduos transplantados hepáticos e avaliar sua segurança. PACIENTES/MÉTODOS: Foram estudados 35 adultos submetidos a transplante hepático. A avaliação do estado nutricional pré-transplante hepático foi realizada pela avaliação nutricional subjetiva global e força do aperto da mão não-dominante, aferida pela dinamometria. A dieta enteral foi iniciada em até 12 horas. A via oral foi iniciada assim que houvesse ruídos hidroaéreos. RESULTADOS: A média de idade dos indivíduos avaliados foi de 45,5 anos (± 8,93). De acordo com a avaliação nutricional subjetiva global, a prevalência de desnutrição pré-transplante foi de 77,1% e pela força do aperto da mão não-dominante de 100%. A nutrição enteral precoce foi iniciada em até 12 horas, moda de 10,9 horas e mantida exclusivamente por período médio de 2,6 dias (± 2,2). Via oral exclusiva foi obtida no período médio de 9,5 dias (± 9,7). A nutrição enteral precoce proveu o aporte calórico estimado em 97% dos casos. Intolerância à dieta enteral ocorreu em cinco indivíduos (14,2%), sendo que em quatro foi reinstituída com sucesso após intervalo de 12 horas. A prevalência de infecção respiratória foi de 28,6%. Em apenas dois pacientes (5,7%) houve broncopneumonia com aspecto aspirativo ao estudo radiológico do tórax. CONCLUSÕES: A nutrição enteral precoce foi um método eficaz na provisão de calorias e seguro em sua aplicação a pacientes transplantados hepáticos.

Abstract
OBJECTIVE To determine the prevalence of malnutrition among liver transplant (LT) candidates. MATERIALS AND METHODS A prospective study evaluated 219 adult LT candidates including 141 men and 78 women. Cholestatic disease was present in 21 (Child: A = 1, B = 11, and C = 9) and noncholestatic disease in 198 (Child: A = 12, B = 93, and C = 93. The mean age was respectively 45.6 and 46.5 years. Anthropometric and biochemical assessments were performed for statistical analysis using Student t test (P <.05). RESULTS In the noncholestatic group, 41.5% were obese according to keep a body mass index (BMI); 61.6% were depleted according to adequacy of tricipital skin fold (%TSF); and 71.1% were above normal levels for generalized adipose reserve (%F). In terms of adequacy of mid-upper arm muscle circumference (%MMC), 58% were depleted and 50.5% were depleted for the current body weight/usual body weight (%CBW/UBW). Otherwise 52.2% of current body weight/ideal body weight (%CBW/IBW) values were above normal. Serum albumin was below normal in 64.9% of cases. In the cholestatic group 62% were normal for BMI; 66.7% were depleted for %TSF; 77.8% were above normal for %F. As to %MMC, 47.6% were depleted and 47.6% were depleted for %CBW/UBW. Otherwise 47.6% were above normal weight for %CBW/IBW. Serum albumin was below normal in 53.9% and %MMC values showed statistically significant differences (P =.02) when compared with Child B and C in the noncholestatic group, as well as %F (P =.01) and serum albumin (P =.0002) in the cholestatic and noncholestatic groups. Serum albumin values also showed statistically significant differences (P =.0004) when noncholestatic Child B and C patients were compared. CONCLUSION Patients with cholestatic disease were more affected by calorie depletion compared to noncholestatic patients who were more affected by protein depletion.

Abstract
BACKGROUND/AIMS To search for changes in body composition and energy metabolism associated with the repeatedly observed weight gain of cirrhotic patients after portosystemic shunting. METHODS Twenty-one patients were studied prospectively before and 6 and 12 months after transjugular intrahepatic portosystemic shunt (TIPS) to assess body cell mass by two independent methods (total body potassium counting: body cell mass determined by TBP, BCMTBP, bioelectric impedance analysis: body cell mass determined by BIA, BCMBIA), muscle mass (anthropometry), resting energy expenditure (REECALO) by indirect calorimetry, and nutritional intake by dietary recall analysis. RESULTS Prior to TIPS patients were hypermetabolic in terms of measured vs. predicted REE (REECALO median 1423 (range 1164-1838) vs. REEPRED 1279 (1067-1687) kcal; P<0.05) and their body cell mass was lower (19.1 (10.9-33.4) vs. 31.7 (16.8-47.1) kg; P=0.001). After TIPS body cell mass (BCMBIA) increased to 23.5 (12.7-44.3) (P<0.025) and 25.7 (14.2-39.7) kg (P=0.05) at 6 and 12 months after TIPS and this was confirmed by total potassium counting (BCMTBP before TIPS: 18.8 (10.6-26.7) vs. 22.4 (12.9-28.5) kg at 6 months; P<0.01). Hypermetabolism persisted throughout the study period. Energy and protein intake increased significantly by 26 and 33%. CONCLUSIONS An increase of prognostically relevant variables body cell and muscle mass contributes to the weight gain after TIPS in malnourished patients with cirrhosis and hypermetabolism.

Abstract
AIMS To retrospectively review our liver transplant performance to identify factors that influenced early outcomes and to prospectively test their validity in predicting outcomes. METHODS Clinical records from 190 patients with liver transplants (LT; n = 200) performed between 1991 and 1997 were reviewed and the data evaluated by univariate and multivariate analyses regarding clinical outcome. The prognostic model thus obtained was prospectively evaluated in 55 patients undergoing transplant between 1999 and 2000. RESULTS Main indication for transplant was post-necrotic cirrhosis (61%), mostly HCV(+). The majority of patients were Child-Pugh C status (46%). Post-operative mortality at 3 months was 15.3%. Risk factors predicting death were: Child-Pugh C status (OR 1.3), pre-LT renal insufficiency (OR 5.8), malnutrition (OR 2.9) and technically complex surgery requiring cross-clamping with or without bypass (OR 4.9). None of the donor factors was significant. Prospectively applied to predict outcome in the 55 patients, the model had a sensitivity of 80% and a specificity of 88.8% with a higher-than-anticipated accuracy with a positive predictive value of 61.5% and a negative predictive value of 95.3%. CONCLUSIONS Pre-LT renal insufficiency is the most significant risk factor for early mortality and suggests that LT should be performed before evidence of irreversible renal insufficiency becomes manifest.

Abstract
Maintenance of the gut environment is a key factor in determining outcome in the care of critically ill and postoperative patients. It is especially important to maintain both gastrointestinal secretions, full of anti-infectious and anti-inflammatory compounds, and the gut flora. Prebiotics, usually polysaccharides, exhibit strong bio-activity and the ingestion of prebiotics has been shown to reduce the rate of infection and restore health in sick and postoperative patients. Probiotics may have at least five functions, all of great importance to the sick patients: the reduction or elimination of potentially pathogenic micro-organisms of various kinds; the reduction or elimination of various toxins, mutagens, carcinogens, etc.; modulation of the innate and adaptive immune defence mechanisms; the promotion of apoptosis; and the release of numerous nutrient, antioxidant, growth, coagulation and other factors necessary for recovery. A combination of pre- and probiotics is referred to as 'synbiotics'. Our experience of synbiotic treatment in critically ill patients is limited, but cutting-edge results from studies of severe acute pancreatitis, chronic hepatitis and liver transplantation offer great hope for the future. This is especially important as pharmaceutical treatment, including the use of antibiotics, has largely failed, and the medical world is in much need of new treatment paradigms.

Abstract
Malnutrition is still a largely unrecognized problem in hospitals. Malnutrition in hospitalized patients is generally related to increasing morbidity and mortality, and costs and length of stay. The aim of this study was to assess the nutritional status of patients on admission to a general hospital using different nutritional scores and to test the sensitivity and specificity of these scores. Sample population included 60 patients (55% male; 45% female) selected (aged 65.6+/-15.9 y) at random by using a computer software program. The nutritional state assessment was performed within 48 h of admission, using different nutritional indices (Subjective Global Assessment (SGA), Nutritional Risk Index (NRI), Gassull classification, Instant Nutritional Assessment (INA) and a combined index). About 78.3% of patients were found to be malnourished on admission. The frequency of malnutrition degree varied from 63.3% as assessed by the SGA to 90% with the NRI. Malnutrition severity was not related to the diagnosis. However, an elderly population was associated with a higher prevalence of malnutrition. INA was the best single score to identify patients who are malnourished or at risk of malnutrition and who may benefit from nutrition support.

Abstract
Cirrhotic patients may become candidates for elective and emergency surgery. This may be due to conditions requiring operations such as cholecystectomy, herniotomy, or gastrointestinal malignancies, more common in cirrhotics when compared with the general population, or to complications of the liver disease such as resectable hepatocellular carcinomas or surgical portosystemic shunts to treat portal hypertension. It has been estimated that 10% of cirrhotics undergo at least one operative procedure during the final 2 y of their lives. Many studies have documented a high risk of morbidity and mortality associated with surgical procedures in these patients, and several factors influencing the postoperative outcome have been identified. Malnutrition, which is frequently encountered in cirrhotic patients, has been shown to have an important impact on the surgical risk. A poor nutrition status also has been associated with a higher risk of complications and mortality in patients undergoing liver transplantation. Few data are available concerning the perioperative nutrition support in surgical cirrhotic patients. The results of these studies are sometimes encouraging in reporting that the nutrition therapy may improve the clinical outcome in cirrhotic patients undergoing general surgery and/or liver transplantation. The limited number of patients and their heterogeneity, however, do not allow definitive conclusions, and more research on this issue is needed.

Abstract
Nutritional abnormalities almost uniformly accompany the metabolic disturbances of severe chronic liver disease and may adversely affect patient well-being and survival, especially surrounding liver transplantation surgery. The exact metabolic alterations responsible for malnutrition and its consequences in these patients have been debated and are a focus of this review. Disturbances in energy production and utilization, as well as macro- and micronutrient metabolism have been appreciated but are not always easily identified or quantifiable. Interestingly, the manifestations of poor nutritional status can vary substantially between patients, even in those having the same etiology and severity of illness. Proper assessment of patients with liver disease for malnutrition carries its own challenges, but some of the more easily applied techniques, such as anthropometry, can be comparable in accuracy to more sophisticated measuring tools. Gaining an appreciation and understanding of how nutritional disturbances develop and can contribute to morbidity and mortality will help combat inappropriate nutritional losses in this specialized group of patients. In many instances, simple adjustments in diet can offset losses and stabilize or improve the patient's nutritional status.

Abstract
BACKGROUND Early enteral nutrition with solutions containing prebiotics (fiber) and probiotics (Lactobacillus) is suggested to reduce bacterial translocation and minimize the incidence of infections after liver transplantation. METHODS In a prospective, randomized placebo-controlled trial consisting of 95 patients, we compared the incidence of postoperative infections and other complications after liver transplantation among three different groups, all supplied with early enteral nutrition: (a) standard formula plus selective bowel decontamination (SBD), (b) fiber-containing formula plus living Lactobacillus plantarum 299, and (c) fiber-containing formula plus heat-killed L plantarum 299. RESULTS The groups were comparable regarding preoperative American Society of Anesthesiologists classification, Child-Pugh classification of cirrhosis, operative data, and degree of immunosuppression. The patients who received living lactobacilli plus fiber developed significantly fewer bacterial infections (13%) than the patients with SBD (48%). The incidence of infections was 34% in the group with inactivated lactobacilli and fiber. Cholangitis and pneumonia were the leading infections and enterococci the most commonly isolated bacteria. In the living Lactobacillus group, the mean duration of antibiotic therapy, the mean total hospital stay, and the stay on the intensive care unit were also shorter than in the groups with inactivated lactobacilli and fiber as well as with SBD. However, these differences did not reach statistical significance. CONCLUSIONS Early enteral nutrition with fiber-containing solutions and living L plantarum 299 was well tolerated. It decreases markedly the rate of postoperative infections both in comparison with inactivated L plantarum 299 and significantly with SBD and a standard enteral nutrition formula. As it is a cheap and feasible alternative to SBD, further studies should evaluate whether this ecoimmunonutrition should be already started while patients are on the waiting list for transplantation.

Abstract
BACKGROUND The subjective global assessment is a clinical method for nutritional assessment that considers not only body composition alterations but also changes in physiological function. The method is simple, inexpensive and non-invasive, and it can be performed at bedside, and its use was described for the first time almost two decades ago. AIM To review the validity studies of subjective global assessment described in literature in the last two decades of its use. METHODS It was performed a systematic review in MEDLINE, using "subjective global assessment" as search term and the most relevant papers were selected. RESULTS Being a subjective method, its precision depends on the observer's experience. Nevertheless, the method showed a good diagnostic precision when performed by trained observers. Subjective global assessment was validated by convergent validity, when this method was compared to other objective nutritional assessment methods, and by predictive validity, showing that subjective global assessment could identify patients who were at high risk for developing postoperative complications. CONCLUSIONS Subjective global assessment has been a good option in nutritional assessment in surgical patients and some modifications have been suggested to adjust the method to other clinical situations. The observer experience is of extreme importance, since the precision of the method depends on it.

Abstract
Malnutrition is common in severe liver disease. Assessment of malnutrition usually requires a subjective global assessment of the patient with a few additional tests that often include handgrip strength and arm-muscle circumference. The severity of liver disease correlates well with the severity of malnutrition, which has prognostic value. Malnutrition is multifactorial, is difficult to correct, and occurs in liver disease independently of the etiology of hepatic injury. Patients who have severe protein-calorie malnutrition require diets with high calorie and protein intake, even in the presence of hepatic encephalopathy. Some forms of complementary and alternative medicine are frequently used in patients with advanced liver disease, but supporting scientific data is needed. Obesity is detrimental to patients with advanced liver disease and is of greater concern in liver transplant candidates because it increases transplant-related morbidity. Data detailing the effects of aggressive nutritional support before transplantation are scarce, and more studies are needed.

Abstract
O sucesso dos transplantes de fígado certamente seria comprometido se a avaliação pré-operatória dos pacientes não fosse realizada de forma adequada. Isto se justifica devido ao reconhecimento de que o sucesso da cirurgia depende, em princípio, do diagnóstico da doença de base, da determinação de sua extensão e do grau de repercussão sistêmica. No final das décadas de setenta a noventa os progressos da hepatologia na identificação das hepatites virais e no manejo da ascite e da síndrome hepatorrenal melhoraram sobremaneira a expectativa de vida do doente portador de doença hepática crônica. Mas, sem dúvida o transplante ortotópico do fígado (TOF) foi o espetacular avanço da hepatologia moderna. Atualmente o transplante é um tratamento eficaz das hepatopatias crônicas, e o índice de sobrevivência global aos 3 anos é ao redor de 80%. É, portanto, uma alternativa de tratamento indicada nos casos terminais, onde a mortalidade com tratamentos conservadores pode atingir até 70% ao final de 12 meses. Neste artigo, os autores comentam aspectos do TOF, relacionados à indicação e a sobrevida.

Abstract
BACKGROUND Malnutrition is a common complication of end-stage liver disease. It is frequently not a priority of treatment before liver transplantation. The purpose of this study was to examine whether prospective preoperative nutritional assessment could predict resource utilization and outcome after liver transplantation. METHODS We retrospectively reviewed 109 sequential orthotopic liver transplants performed at our center between July 1996 and May 1999. Ten patients with fulminant hepatic failure were excluded from the study, leaving 99 patients. Nutritional status was determined at the time of transplantation using subjective global assessment. Wilcoxon rank sum test and rank analysis of variance were used to analyze the data. Results are reported as median (interquartile range). A P value <0.05 was considered significant. RESULTS Intraoperative transfusion requirements of packed red blood cells and cryoprecipitate was higher in the patients with severe malnutrition in comparison to the mild and moderate groups (severe vs. moderate, 5.5+/-5.5 vs. 3.0+/-6, P=0.026; vs. mild, 1.5+/-3, P<0.0001). The severe group required more fresh-frozen plasma intraoperatively than the mild group (mild vs. severe, 0+/-2 vs. 2+/-6, P=0.0007; vs. moderate, 1+/-4, P=0.071). Patients in the severe group had longer postoperative lengths of stay compared with patients in the moderate and mild groups (severe vs. moderate, 16+/-9 days vs. 10+/-5 days, P=0.0027; vs. mild, 9+/-8 days, P=0.0006). CONCLUSIONS Subjective global assessment is an excellent independent predictor of outcome in patients undergoing liver transplantation. Severely malnourished patients require more blood products during surgery and have prolonged postoperative length of stay in hospital. Our data suggest that if nutritional repletion is possible in patients with end-stage liver disease before transplantation, patient outcomes could be improved.

Abstract
OBJECTIVE To quantify the sequential changes in the metabolic response occurring in patients with end-stage liver disease after orthotopic liver transplantation (OLT). SUMMARY BACKGROUND DATA Detailed quantification of the changes in energy expenditure, body composition, and physiologic function that occur in patients after OLT has not been performed. Understanding these changes is essential for the optimal management of these patients. METHODS Fourteen patients who underwent OLT for end-stage liver disease had measurements of resting energy expenditure, body composition, and physiologic function immediately before surgery and 5, 10, 15, 30, 90, 180, and 360 days later. RESULTS Resting energy expenditure was significantly elevated after surgery (24% above predicted), peaking around day 10 after OLT, when it averaged 42% above predicted. A significant degree of hypermetabolism was still present at 6 months, but at 12 months measured resting energy expenditure was close to predicted values. Before surgery, measured total body protein was 82% of estimated preillness total body protein. During the first 10 days after OLT, a further 1.0 kg (10%) of total body protein was lost, mostly from skeletal muscle. Only 54% of this loss was restored by 12 months. Significant overhydration of the fat-free body was seen before OLT, and it was still present 12 months later. Although significant losses of body fat and bone mineral occurred during the early postoperative period, only body fat stores were restored at 12 months. Both subjective fatigue score and voluntary hand grip strength improved rapidly after OLT to exceed preoperative levels at 3 months. At 12 months grip strength was close to values predicted for these patients when well. Respiratory muscle strength improved less markedly and was significantly lower than predicted normal levels at 12 months. CONCLUSIONS Before surgery, these patients were significantly protein-depleted, overhydrated, and hypermetabolic. After surgery, the period of hypermetabolism was prolonged, restoration of body protein stores was gradual and incomplete, and respiratory muscle strength failed to reach expected normal values. Our measurements indicate that OLT does not normalize body composition and function and imply that a continuing metabolic stress persists for at least 12 months after surgery.

Abstract
BACKGROUND Extremes in body weight are a relative contraindication to cardiac transplantation. METHODS We retrospectively reviewed 474 consecutive adult patients (377 male, 97 female, mean age 50.3+/-12.2 years), who received 444 primary and 30 heart retransplants between January of 1992 and January of 1999. Of these, 68 cachectic (body mass index [BMI]<20 kg/m2), 113 overweight (BMI=>27-30 kg/m2), and 55 morbidly obese (BMI>30 kg/m2) patients were compared with 238 normal-weight recipients (BMI=20-27 kg/m2). We evaluated the influence of pretransplant BMI on morbidity and mortality after cardiac transplantation. Kaplan-Meier survival distribution and Cox proportional hazards model were used for statistical analyses. RESULTS Morbidly obese as well as cachectic recipients demonstrated nearly twice the 5-year mortality of normal-weight or overweight recipients (53% vs. 27%, respectively, P=0.001). An increase in mortality was seen at 30 days for morbidly obese and cachectic recipients (12.7% and 17.7%, respectively) versus a 30-day mortality rate of 7.6% in normal-weight recipients. Morbidly obese recipients experienced a shorter time to high-grade acute rejection (P=0.004) as well as an increased annual high-grade rejection frequency when compared with normal-weight recipients (P=0.001). By multivariable analysis, the incidence of transplant-related coronary artery disease (TCAD) was not increased in morbidly obese patients but cachectic patients had a significantly lower incidence of TCAD (P=0.05). Cachectic patients receiving oversized donor hearts had a significantly higher postoperative mortality (P=0.02). CONCLUSIONS The risks of cardiac transplantation are increased in both morbidly obese and cachectic patients compared with normal-weight recipients. However, the results of cardiac transplantation in overweight patients is comparable to that in normal-weight patients. Recipient size should be kept in mind while selecting patients and the use of oversized donors in cachectic recipients should be avoided.

Abstract
Timely nutrition assessment and intervention in organ transplant recipients may improve outcomes surrounding transplantation. A pretransplant nutrition assessment should include a variety of parameters including physical assessment, history, anthropometric measurements, and laboratory tests. Malnutrition compromises posttransplant survival; prolonged waiting times worsen outcomes when patients are already malnourished. Severe obesity may decrease graft function and survival in kidney transplant recipients. In the pretransplant phase, nutritional goals include optimization of nutritional status and treatment of nutrition-related symptoms induced by organ failure. Enteral tube feeding is indicated for patients with functional gastrointestinal tracts who are not eating adequately. Parenteral nutrition is rarely needed pretransplant except in cases of intestinal failure. When determining pretransplant nutrient requirements, nutritional status, weight, age, gender, metabolic state, stage and type of organ failure, malabsorption, induced losses, goals, and comorbid conditions must be considered. During the acute posttransplant phase, adequate nutrition is required to help prevent infection, promote wound healing, support metabolic demands, replenish lost stores, and perhaps mediate the immune response. Nutrient recommendations reflect posttransplant metabolic changes. The appropriateness of posttransplant nutrition support depends on the prevalence of malnutrition among patients with a specific type of organ failure and the benefits when nutrition support is given. Organ transplantation complications including rejection, infection, wound healing, renal insufficiency, hyperglycemia, and surgical complications require specific nutritional requirements and therapies. Many potential applications of nutrition in the pre- and posttransplant phases exist and require further study.

Abstract
BACKGROUND It is well documented that malnourished and/or obese surgical patients have increased morbidity and mortality post-operatively. Only a few studies investigating the effect of nutritional status on mortality are available pertaining to the transplant population. Since limited data are available on the nutritional status and its effects on mortality in the lung transplant population, we sought to ascertain whether there is an association between mortality and preoperative nutritional status. METHODS We examined mortality during the first 3 months after transplantation. Patients were grouped by body mass index (BMI) categories as < 17 kg/m(2), 17 to < 20 kg/m(2), 20 to 25 kg/m(2) (reference group), > 25 to 27 kg/m(2), and > 27 kg/m(2). Additional risk factors retrieved from the pre-transplant records included age, gender, diagnosis, energy requirements, protein requirements, protein and caloric intake, and weight history. Logistic regression for univariate and multivariate analysis for mortality used recipient age, gender, disease category, pre-transplant cytomegalovirus (CMV) serology, transplant type (single or bilateral), and donor age, gender, and CMV serology. RESULTS The likelihood estimates or odds ratios (ORs) of the risk of death within 90 days of lung transplantation for the BMI categories compared to the reference group were 3.7 for BMI < 17 kg/m(2) (p = 0.085), 1.6 for BMI < 17 to 20 kg/m(2) (p = 0.455), 3.5 for BMI > 25 to 27 kg/m(2) (p = 0.069), and 5.0 for BMI > 27 kg/m(2) (p = 0.003). CONCLUSIONS In patients with a pre-transplant BMI < 17 kg/m(2) or > 25 kg/m(2) the risk of dying within 90 days post-transplant was increased. In patients with a pre-transplant BMI of > 27 kg/m(2) the risk was significantly higher in than the reference group.

Abstract
BACKGROUND Poor preoperative nutritional status has been reported to be associated with adverse outcomes after liver transplantation. Published data are, however, conflicting, with methods of preoperative nutritional assessment and postoperative outcomes varying between studies. METHODS We prospectively studied the predictive value of preoperative nutritional status for adverse outcomes after liver transplantation. Assessment of preoperative nutritional status included: body cell mass determination, subjective global assessment, anthropometry, handgrip dynamometry, biochemical and amino acid profile, Child's score, and dual-energy x-ray absorptiometry. Death, intensive care unit (ICU) length of stay > or =4 days, hospital length of stay > or =15 days, blood usage > or =36 U of blood products, infection, rejection, and global resource utilization (an index of cost) greater than the median were considered poor outcomes. RESULTS Fifty-three patients were studied. Longer ICU stay was associated with lower handgrip strength (P<0.01) and lower aromatic amino acid levels (P<0.01). Longer total hospital stay and the development of infections were associated with lower branched chain amino acid levels (P<0.01 and <0.001, respectively). Acute cellular rejection was associated with lower total body fat (P<0.001) and higher triglyceride levels (P<0.02). Neither death nor higher global resource utilization was associated with any preoperative nutritional parameter. CONCLUSIONS Lower preoperative handgrip strength and branched chain amino acid levels are associated with longer ICU stays and increased likelihood of posttransplant infections. In our program, in which nutritional support was provided to potential recipients exhibiting malnourishment, none of the measured nutritional parameters were associated with mortality or greater global resource utilization.

Abstract
Successful liver transplantation in a child is often a hard-won victory, requiring all the combined expertise of a dedicated pediatric transplant team. This article outlines the considerable challenges still facing pediatric liver transplant physicians and surgeons. In looking to the future, where should priorities lie to enhance the success already achieved? First, solutions to the donor shortage must be sought aggressively by increasing the use of from split-liver transplants, judicious application of living-donor programs, and increasing the donation rate, perhaps by innovative means. The major immunologic barriers, to successful xenotransplantation make it unlikely that this option will be tenable in the near future. Second, current immunosuppression is nonspecific, toxic, and unable to be individually adjusted to the patient's immune response. The goal of achieving donor-specific tolerance will require new consideration of induction protocols. Developing a clinically applicable method to measure the recipient's immunoreactivity is of paramount importance, for future studies of new immunosuppressive strategies and to address the immediate concern of long-term over-immunosuppression. The inclusion of pediatric patients in new protocols will require the ongoing insistence of pediatric transplant investigators. Third, the current immunosuppressive drugs have a long-term morbidity and mortality of their own. These long-term effects are particularly important in children who may well have decades of exposure to these therapies. There is now some understanding of their long-term renal toxicity and the risk of malignancy. New drugs may obviate renal toxicity, whereas the risk of malignancy is inherent in any nonspecific immunosuppressive regimen. Although progress is being made in preventing and recognizing PTLD, this entity remains an important ongoing concern. The global effect of long-term immunosuppression on the child's growth, development, and intellectual potential is unknown. Of particular concern is the potential for neurotoxicity from the calcineurin inhibitors. Fourth, recurrent disease and new diseases, perhaps potentiated by immunosuppressive drugs, must be considered. Already the recurrence of autoimmune disease and cryptogenic cirrhosis have been documented in pediatric patients. Now, a new lesion, a nonspecific hepatitis, sometimes with positive autoimmune markers, that may progress to cirrhosis has been recognized. It is not known whether this entity is an unusual form of rejection, an unrecognized viral infection, or a response to immunosuppressive drugs themselves. Finally, pediatric transplant recipients, like any other children, must be protected and nourished physically and mentally if they are to fulfill their potential. After liver transplantation the child's growth, intellectual functioning, and psychologic adaptation may all require special attention from parents, teachers, and physicians alike. There is limited understanding of how the enormous physical intervention of a liver transplantation affects a child's cognitive and psychologic function as the child progresses through life. The persons caring for these children have the difficult responsibility of providing services to evaluate these essential measures of children's health over the long term and to intervene if necessary. Part of the transplant physician's our duty to protect and advocate for children is to fight for equal access to health care. In most of the developing world, economic pressures make it impossible to consider liver transplantation a health care priority. In the United States and in other countries with the medical infrastructure to support liver transplantation, however, health care professionals must strive to be sure that the policies governing candidacy for transplantation and allocation of organs are applied justly and uniformly to all children whose lives are threatened by liver disease. In the current regulatory climate that increasingly takes medical decisions out of the hands of physicians, pediatricians must be even more prepared to protect the unique and often complicated needs of children both before and after transplantation. Only in this way can the challenges of the present and the future be met.

Abstract
BACKGROUND/AIMS Energy charge and capacity for adenosine triphosphate (ATP) synthesis have been demonstrated to play a major role in the maintenance of organ function after liver preservation for transplantation. The aim of this study was to evaluate whether a supply of liposomally-entrapped ATP during preservation could improve the energy state and metabolism of cold-stored rat liver. METHODS In the first set of experiments, the uptake of ATP-containing liposomes and their effects on hepatic viability were determined in isolated perfused unstored rat liver. In the second set of experiments, rat livers were preserved for 18 h at 4 degrees C in UW solution in the presence of these liposomes, and effects on energy state, cell volume and metabolism were evaluated. In each part, data were compared with adequate control, unloaded liposome-treated, and free ATP-treated groups (n=6 in each group). RESULTS In non-stored livers, ATP-containing liposomes were taken up by the liver; they did not alter hepatic viability and induced a decrease in energy substrate consumption (glucose and amino acids), and an improvement in intrahepatic ATP content (+23% vs. Control). Addition of liposomally-entrapped ATP during cold storage produced a significant attenuation of the decrease in hepatic ATP content (Lip ATP 2: 524+/-45 vs. Control 2: 364+/-106 nmol/g; p<0.05), and induced, during reperfusion, a decrease in proteolysis associated with an increase in cell volume compared with the other groups (Lip ATP 2: 633+/-63 vs. Control 2: 532+/-38, Unloaded Lip 2: 483+/-55 and Free ATP 2: 500+/-29 microl/g; p<0.01). CONCLUSIONS These data indicate that liposomally-entrapped ATP represents an effective means to improve liver graft energy state and function. The decrease in protein degradation may be related to the modification of cell volume.

Abstract
BACKGROUND Poor nutritional status is common among patients awaiting orthotopic liver transplantation and is associated with poor outcome. METHODS This prospective randomized controlled trial examined the effect of pretransplant nutritional supplementation on the outcome of patients undergoing liver transplantation. Of 82 consecutive patients with mid-arm muscle circumference <25th percentile, 42 received enteral supplementation, and the remainder acted as the control group. The supplemented group received a calorie-dense enteral feed taken daily (in addition to diet) until transplantation. Nutritional status was monitored by upper arm anthropometric measurements and handgrip strength. Dietary intake was calculated from 5-day food diaries. RESULTS Supplementation improved mid-arm circumference, mid-arm muscle circumference, and grip strength. Pretransplant nutritional status was not associated with posttransplant sepsis or major complications. Preoperative grip strength of <85% of normal values was predictive of increased incidence of posttransplant major complications. Supplementation did not affect outcome, although there were more deaths in the control group (seven deaths before and two deaths after transplant) than there were in the supplemented group (two deaths before and three deaths after transplant). There was no difference in overall survival (P = 0.075). CONCLUSIONS Enteral supplementation improved some parameters of nutritional status pretransplant. Dietary intake of patients in the two groups was similar at transplant. Nutritional supplementation has not increased nutritional intake, although this may reflect the importance of regular dietetic input and support, rather than suggesting that nutritional supplementation is ineffective. Supplementation had no effect on outcome of liver transplantation.

Abstract
Many hospitalized patients are malnourished, and the relationship between malnutrition and patient outcome is well established. To determine which patients are at nutritional risks, clinical scores are probably more accurate than using a single nutritional parameter. Among the numerous scores published, both the Prognostic Nutritional Index and the Subjective Global Assessment were prospectively validated. One is based on objective measurements, whereas the second is based on medical history and physical examination. The Nutritional Risk Index has been used in many studies including the "Veterans Study." The Mini Nutritional Assessment is a promising score for evaluating malnutrition in the elderly. The development of nutritional scores for use by nurses may facilitate screening of a large number of hospitalized patients.

Abstract
Measurements of resting energy expenditure (REE) can be used to determine energy requirements. Prediction formulae can be used to estimate REE but have not been validated in cirrhotic patients. REE was measured, by indirect calorimetry, in 100 cirrhotic patients and 41 comparable healthy volunteers, and the results compared with estimates predicted using the Harris-Benedict, Schofield, Mifflin, Cunningham, and Owen formulae, and the disease-specific Müller formula. The mean (+/- 1 SD) measured REE in the healthy volunteers (1,590 +/- 306 kcal/24 h) was significantly greater than the mean Harris-Benedict, Mifflin, Cunningham, and Owen predictions but comparable with the mean Schofield prediction; individual predicted values varied widely from measured values (95% limits of agreement, -460 to +424 kcal). The mean measured REE in the cirrhotic patients was significantly greater than in the healthy volunteers (23.2 +/- 3. 8 cf 21.9 +/- 2.9 kcal/kg/24 h; P <.05). The mean measured REE in the cirrhotic patients (1,660 +/- 337 kcal/24 h) was significantly different from mean predicted values (Harris-Benedict, 1,532 +/- 252 kcal/24 h, P <.0001; Schofield, 1,575 +/- 254 kcal/24 h, P <.0005; Mifflin, 1,460 +/- 254 kcal/24 h, P <.0001; Cunningham, 1,713 +/- 252 kcal/24 h, P <.05; Owen, 1,521 +/- 281 kcal/24 h, P <.0001; Müller, 1,783 +/- 204 kcal/24 h, P <.0001); individual predicted values varied widely from measured values (95% limits of agreement, -632 to +573 kcal). Simple regression analysis showed that fat-free mass (FFM) was the strongest predictor of measured REE in the cirrhotic patients, accounting for 52% of the variation observed. However, a population-specific prediction equation, derived using stepwise regression analysis, which incorporated FFM, age, and Pugh's score, accounted for only 61% of the observed variation in measured REE. REE should, therefore, be measured in cirrhotic patients, not predicted.

Abstract
BACKGROUND The relationship between pre-transplant body weight and post-transplant outcome has only recently been identified using a single, indirect measure of weight (percent ideal body weight [PIBW]). The literature is equivocal regarding which index is the better indicator of body weight. The purpose of this study was to determine (1) if pre-heart transplant body weight, measured by body mass index (BMI) and PIBW, is associated with post-heart transplant morbidity and mortality and (2) if patient gender, age, and etiology of heart disease affect this association. METHODS The sample included 4,515 patients who received a heart transplant from January 1, 1990-December 31, 1995 at 38 institutions participating in the Cardiac Transplant Research Database (CTRD). Patients were divided into groups according to their BMI and PIBW. Data were described using frequencies, measures of central tendency, Pearson correlation coefficients, stratified actuarial analyses and log rank tests for comparisons, and a multivariable risk factor analysis in the hazard domain. RESULTS For all patients (n = 4,515), being <80% or >140% of IBW before heart transplant was a risk factor for increased mortality after heart transplant. The association between pre-heart transplant PIBW and post-heart transplant survival was affected by gender, age, and etiology of heart disease. In males, a higher PIBW was a significant risk factor for death early after transplant (p = .0003). Although not significant, there was a trend for a higher PIBW being a risk factor for death in females throughout the post transplant period (p = .07). No differences in cause of death were found for PIBW and BMI. In male and female recipients <55 years, being overweight pre-heart transplant was a risk factor for infection. In patients with pre-transplant ischemic heart disease, the greatest risk for infection was found in patients who were >140% of IBW. Pre-heart transplant BMI and PIBW were not associated with acute rejection or cardiac allograft arteriopathy after transplant. CONCLUSIONS In conclusion, being cachectic or obese preoperatively is associated with decreased survival in all patients after heart transplantation. Being obese preoperatively is associated with increased infection after heart transplant in males and females <55 years and in patients with ischemic heart disease. Of the 2 indices of body weight used in this study, percent ideal body weight appears to be the better predictor of future morbidity and mortality following heart transplantation.

Abstract
Nutritional support is often necessary in chronic liver disease in childhood, and when enteral nutrition is insufficient, parenteral nutrition (PN) can be envisaged as a last resort. Pediatric experience is still limited in this indication. Seven children with severe liver disease received PN for a mean duration of 105 d, with additional enteral nutrition. Clinical tolerance was assessed and anthropometric and biological data were compared at the beginning and at the end of the study by the paired non-parametric test of Wilcoxon. Weight change, expressed as weight-for-age or weight-for-height Z-scores, increased. Conjugated bilirubin increased significantly. This retrospective study suggests that PN is a well-tolerated method for maintaining nutritional status in pediatric chronic liver disease when enteral nutrition has failed.

Abstract
INTRODUCTION The shortage of cadaveric organ donors imposes a severe limit to the number of liver transplantations. A selection is thus necessary among patients: should the sickest be selected, or those who supposedly have the best chance to survive and recover? Optimizing the timing of transplantation during the course of the disease (not too early, but not too late) is another issue. CURRENT KNOWLEDGE AND KEY POINTS Suitable candidates for transplantation are patients suffering from an irreversible, symptomatic liver disease. The goals of therapy are: firstly, to favorably modify the natural outcome of the disease; and secondly, in an acceptable risk taking manner. Major criteria for indication in the most common liver diseases can be summarized as follows: a) for chronic parenchymal liver diseases, a Child-Pugh score of 9 or 10, or less if complications have already occurred, is a mandatory and often sufficient criterion; b) for cholestatic liver diseases, a serum bilirubin level higher than 100-150 mumol/L is generally required; c) apart from "small" hepatocellular carcinomas on cirrhotic parenchyma (less than three tumors of less than 5 cm in diameter), most cancers are considered contraindications; d) acute liver failure requires early referral to a liver transplant center for potential emergency indication. FUTURE PROSPECTS AND PROJECTS In an organ shortage situation which is likely to perdure, early consultative contact between the patient and the liver transplant team will allow improvement in the access to transplantation procedure.
