Abstract
An update to the American Society for Parenteral and Enteral Nutrition guidelines for nutrition provision in critically ill adults was published in 2022. In contrast to the previous set of guidelines published in 2016, the revised guidelines selected only studies meeting specific criteria for scientific rigor and only considered publications reflecting more modern intensive care unit (ICU) practices (studies between January 1, 2001, and July 15, 2020). No consensus recommendations were included. Although these methods limited the number of recommendations made and the applicability to current ICU practices, important implications for patient care were evaluated and acknowledged. The literature supporting guideline recommendations that impact parenteral nutrition management is summarized in this review, along with key studies published after the guidelines were revised. Considerations for practical application of this evidence, along with limitations and future guideline directions, are also described.

Abstract
Enteral nutrition should be initiated within 24 to 48 hours of injury, starting at a trophic rate and increasing to goal rate after hemodynamic stability is achieved. The modified Nutritional Risk in the Critically Ill score can help identify patients who will benefit most from aggressive and early nutritional intervention. In the first week of critical illness, the patient should receive only 70% to 80% of estimated calories and protein should be targeted to 1.5 to 2 g/kg. Parenteral nutrition can be provided safely without increased adverse events. Peri-operative (and intra-operative) feeding has been shown to be safe in selected patients.

Abstract
BACKGROUND Malnutrition continues to be associated with outcomes in hospitalized patients. METHODS An updated review of national data in patients with a coded diagnosis of malnutrition (CDM) and the use of nutrition support (enteral nutrition [EN] and parenteral nutrition [PN]) was conducted using the Agency for Healthcare Research and Quality Healthcare Cost and Utilization Project and Medicare Claims data. RESULTS Results demonstrated a growing trend in CDM accompanied by continued low utilization of PN and EN. CONCLUSION Underutilization of nutrition support may be due to product shortages, reluctance of clinicians to use these therapies, undercoding of nutrition support, strict adherence to published guidelines, and other factors.

Abstract
To explore the effects of nutritional support combined with insulin therapy on serum protein, procalcitonin (PCT), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), pentraxin-3 (PTX-3), and serum amylase (AMS) levels in patients with diabetic ketoacidosis complicated with acute pancreatitis.A total of 64 patients with diabetic ketoacidosis complicated with acute pancreatitis admitted to our hospital from January 2018 to February 2019 were enrolled in this prospective study. They were divided into the study group and the control group according to the random number table method, with 32 patients in each group. Patients in the study group were given nutritional support combined with insulin therapy, and patients in the control group were given insulin therapy.There were no significant differences in general data including age, gender, body mass index, course and type of diabetes, acute physiology and chronic health evaluation II, RANSON, CT grades between the 2 groups before treatment (all P > .05). After 7 days of treatment, the clinical efficacy of the study group was significantly higher than that of the control group (study group vs control group, 94.44% vs 75.00%, P < .05). After 7 days of treatment, the levels of prealbumin and albumin in the study group were significantly higher than those in the control group (P < .05). After 7 days of treatment, the levels of PCT, CRP, TNF-α, PTX-3, and AMS in the 2 groups were significantly lower than those before treatment (P < .05), and the levels of PCT, CRP, TNF-α, PTX-3, and AMS in the study group were significantly lower than those in the control group. After 7 days of treatment, the levels of IgG, IgM, and IgA in the 2 groups were significantly higher than those before treatment, and the levels of IgG, IgM, and IgA in the study group were significantly higher than those in the control group (P < .05).Nutritional support combined with insulin is obviously effective in the treatment of diabetic ketoacidosis complicated with acute pancreatitis, which can improve serum protein levels, reduce inflammatory response, improve immune function, and is worthy of clinical application.

Abstract
PURPOSE OF REVIEW The COVID-19 pandemic is a unique disease process that has caused unprecedented challenges for intensive care specialists. The hyperinflammatory hypermetabolic nature of the disease and the complexity of its management create barriers to the delivery of nutritional therapy. This review identifies the key differences which characterize this pandemic from other disease processes in critical illness and discusses alternative strategies to enhance success of nutritional support. RECENT FINDINGS Prolonged hyperinflammation, unlike any previously described pattern of response to injury, causes metabolic perturbations and deterioration of nutritional status. High ventilatory demands, hypercoagulation with the risk of bowel ischemia, and threat of aspiration in patients with little or no pulmonary reserve, thwart initial efforts to provide early enteral nutrition (EN). The obesity paradox is invalidated, tolerance of EN is limited, intensivists are reluctant to add supplemental parenteral nutrition (PN), and efforts to give sufficient nutritional therapy remain a low priority. The nature of the disease and difficulties providing traditional critical care nutrition lead to dramatic deterioration of nutritional status. Institutions should not rely on insufficient gastric feeding alone but focus instead on redoubling efforts to provide postpyloric deep duodenal/jejunal EN or re-examine the role of supplemental PN in this population of patients with such severe critical illness.

Abstract
Critically ill (intensive care unit [ICU]) patients are characterized by organ failure, intense inflammatory response, insulin resistance, and altered metabolic response. The sicker the patient, the higher the threat to nutrition and micronutrient status. In addition, many patients start the ICU stay with an altered nutrition status, which requires assessment upon admission. Nutrition needs vary among patients as well as during hospitalization, as the metabolic response changes over time. Shock and acute organ failure result in a metabolic shift toward intense catabolism: endogenous glucose production aiming at ensuring the basal adenosine triphosphate production starts immediately and occurs at the expense of the lean body mass using amino acids for neoglucogenesis. Later, the stabilization and recovery phases are characterized by higher energy and substrate needs. Indirect calorimetry is the only tool enabling determination of the metabolic level. When and how should feeding be started? Recent research shows that the route does not matter much, with equipoise between enteral and parenteral nutrition (PN) as long as overfeeding is avoided. As micronutrients are an integral part of metabolism and antioxidant defenses, their delivery must be ensured: whereas needs are well defined for healthy individuals, needs for illness remain poorly defined. PN that contains only macrosubstrates requires the daily prescription of multimicronutrient complements to qualify as total PN. Achievement of goals requires minimal monitoring, consisting of the daily verification of energy and protein goal delivery achievement and daily follow-up determining blood glucose and phosphate levels and insulin requirements.

Abstract
La réponse métabolique à l’agression correspond à un ensemble de réactions à la base de l’adaptation de l’organisme aux nouvelles conditions. Ces modifications concernent des aspects métaboliques spécifiques comme le maintien de la masse protéique et/ou l’état des réserves énergétiques. L’une des principales difficultés de l’optimisation du support métabolique consiste à distinguer les changements métaboliques bénéfiques de ceux qui sont délétères pour l’organisme. Dans ce contexte, les objectifs thérapeutiques peuvent se limiter à une approche nutritionnelle s’attachant à limiter le déficit énergétique et les pertes protéiques et musculaires. Ils peuvent être plus ambitieux en essayant d’adapter les apports aux différents besoins d’un point de vue quantitatif comme qualitatif. La limitation du déficit énergétique semble être un objectif raisonnable à atteindre selon les données de la littérature. Enfin, essayer d’interférer avec la réponse métabolique à l’agression (immunomodulation, manipulations pharmacologiques des voies métaboliques, etc.) représente le degré d’intervention métabolique le plus élaboré et, si quelques données ont pu être encourageantes, il n’est pas possible d’affirmer que cet objectif soit complètement réaliste, voire même bénéfique. Les apports nutritionnels doivent être intégrés à la stratégie thérapeutique globale de prise en charge. La réponse optimale du support nutritionnel a pour but « de donner les moyens métaboliques » de la guérison.

Abstract
PURPOSE OF REVIEW Feeding guidelines have recommended early, full nutritional support in critically ill patients to prevent hypercatabolism and muscle weakness. Early enteral nutrition was suggested to be superior to early parenteral nutrition. When enteral nutrition fails to meet nutritional target, it was recommended to administer supplemental parenteral nutrition, albeit with a varying starting point. Sufficient amounts of amino acids were recommended, with addition of glutamine in subgroups. Recently, several large randomized controlled trials (RCTs) have yielded important new insights. This review summarizes recent evidence with regard to the indication, timing, and dosing of parenteral nutrition in critically ill patients. RECENT FINDINGS One large RCT revealed no difference between early enteral nutrition and early parenteral nutrition. Two large multicenter RCTs showed harm by early supplementation of insufficient enteral nutrition with parenteral nutrition, which could be explained by feeding-induced suppression of autophagy. Several RCTs found either no benefit or harm with a higher amino acid or caloric intake, as well as harm by administration of glutamine. SUMMARY Although unanswered questions remain, current evidence supports accepting low macronutrient intake during the acute phase of critical illness and does not support use of early parenteral nutrition. The timing when parenteral nutrition can be initiated safely and effectively is unclear.

Abstract
BACKGROUND An enterocutaneous fistula (ECF) is an aberrant connection between the gastrointestinal tract and the skin or atmosphere (enteroatmospheric fistula [EAF]). Multimodal treatment includes surgical procedures, nutrition support, and wound care. We evaluated our practice and compared our outcomes with previous results published from our institution. MATERIALS AND METHODS We performed a retrospective analysis of hospitalized ECF/EAF patients admitted between January 2011 and November 2015. Patients with internal fistulas; active inflammatory bowel disease; malignancy; radiation treatment; end-stage renal, hepatic, or cardiac disease; and active alcoholism were excluded. Data collected included demographics, fistula characteristics, nutrition therapy, treatment, operative success, and hospital mortality. Parametric and nonparametric tests for independent and paired groups were performed. RESULTS Thirty-one patients were included in the analysis. The median (interquartile range) age was 60 (53-76) years, and 81% were female. Parenteral nutrition was initially prescribed in 80% of patients, but 61% received enteral nutrition (EN) at some point during their hospitalization. Two patients were fed by fistuloclysis. Eighty percent of the patients underwent surgical repair a median of 12 months after diagnosis with 92% operative success. Surgical repair had a modest correlation with home discharge (ρ = 0.517, P = .003). A large proportion of patients (77%) were discharged home. The in-hospital mortality at our institution decreased from 44% in 1960 to 21% in 1970 to 3% in the current study. CONCLUSIONS Modern treatment of ECF/EAF, including EN and advanced local wound care, is associated with improvements in clinical outcomes such as hospital mortality.

Abstract
Critically ill people are unable to eat. What’s the best way to feed them? Nutrition authorities have long recommended providing generous amounts of protein and calories to critically ill patients, either intravenously or through feeding tubes, in order to counteract the catabolic state associated with this condition. In practice, however, patients in modern intensive care units are substantially underfed. Several large randomized clinical trials were recently carried out to determine the clinical implications of this situation. Contradicting decades of physiological, clinical, and observational data, the results of these trials have been claimed to justify the current practice of systematic underfeeding in the intensive care unit. This article explains and suggests how to resolve this conundrum.

Abstract
Invasive fungal infections have become an increasingly prevalent and disturbing problem in critically ill patients. The advent of broad-spectrum antibacterial therapy and immunosuppressant therapy, among other factors such as mechanical ventilation, places the intensive care patient at significant risk for infection with pathogenic fungi. Most patients who become infected with invasive fungi, especially Candida species, have been previously colonized with the offending organism, lending to the notion that colonization precedes infection inmany cases. Despite an ever-increasing array of antifungal therapy for these infections, mortality rates remain extremely high, especially when the bloodstream is the primary site of infection. In addition, a shift toward more resistant pathogens such asCandida glabrata, Candida krusei, and moldswill provide clinicianswith therapeutic challenges for many years. The wide variation in acquisition cost across antifungal agents adds an additional layer of complexity to clinical decision making. Newer antifungal agents, each with its own advantages and disadvantages, have become available in recent years. Placing each agent in its appropriate niche is a dilemma that has yet to be solved.

Abstract
Knowledge about acute pancreatitis has increased recently in both the medical and veterinary fields. Despite this expansion of knowledge, there are very few studies on treatment interventions in naturally occurring disease in dogs. As a result, treatment recommendations are largely extrapolated from experimental rodent models or general critical care principles. General treatment principles involve replacing fluid losses, maintaining hydrostatic pressure, controlling nausea and providing pain relief. Specific interventions recently advocated in human medicine include the use of neurokinin-1 antagonists for analgesia and early interventional feeding. The premise for early feeding is to improve the health of the intestinal tract, as unhealthy enterocytes are thought to perpetuate systemic inflammation. The evidence for early interventional feeding is not supported by robust clinical trials to date, but in humans there is evidence that it reduces hospitalisation time and in dogs it is well tolerated. This article summarises the major areas of management of acute pancreatitis in dogs and examines the level of evidence for each recommendation.

Abstract
OBJECTIVES To determine whether recommendations for treatment of acute pancreatitis (AP) in adults impact the outcomes of pediatric AP. STUDY DESIGN Adult guidelines regarding early management of AP were implemented through an admission order set at Cincinnati Children's Hospital Medical Center at the beginning of the year 2014. Recommendations included administering high rates of intravenous fluid (IVF) within 24 hours of admission and enteral nutrition within 48 hours of admission. A retrospective chart review of AP admissions before and after the implementation of the recommendations was undertaken. Outcomes studied were: hospital length of stay, intensive care unit transfer rates, development of severe AP, pulmonary complications, and readmission rates post discharge from the hospital. RESULTS The study included 201 patients. Children who received feeds within the first 48 hours and received greater than maintenance IVF within 24 hours had a shorter length of stay, less intensive care unit admissions and severe AP rates compared with the patients who remained nil per os during the first 48 hours and received lower rates of IVF. CONCLUSION Our data support that early enteral nutrition and early aggressive IVF improve outcomes of pediatric AP.

Abstract
PURPOSE OF REVIEW Recent studies on the optimal modalities to feed patients during the ICU stay show divergent results. The level and the timing of energy provision is a critical issue, associated with the clinical outcome. These results questioned the clinical relevance of the recent guidelines issued by American, Canadian and European academic societies. RECENT FINDINGS Four recent prospective randomized studies enrolled critically ill patients who received various nutritional regimens and tested the effect of nutritional support on outcome. The Tight Calorie balance Control Study (TICACOS) targeted on calorie administration according to measured energy expenditure and found increased ICU morbidity but improved hospital mortality. The large EpaNIC study compared 'early' with 'late' (parenteral nutrition) nutrition, mostly in patients after cardiac surgery, and found an increased morbidity associated with early parenteral nutrition. The supplemental parenteral nutrition (SPN) study randomized the patients after 3 days and targeted the calories administered by parenteral nutrition as a complement to unsuccessful enteral nutrition using indirect calorimetry. The SPN resulted in less nosocomial infections and shorter duration of mechanical ventilation. Finally, a recent Australian study enrolled patients unable to be early fed enterally to receive, or not, parenteral nutrition targeted at 1500 kcal. No complications were noted in the parenteral nutrition group. Lessons from all these studies are summarized and should help in designing better studies and guidelines. SUMMARY The critical analysis of recent prospective studies comparing various levels of calorie administration, enteral versus parenteral nutrition and enteral versus SPN confirms the recommendations to avoid underfeeding and overfeeding. Parenteral nutrition, required if enteral feeding is failing, and if adjusted up to a measured optimal level, may improve outcome. More studies on the optimal level of energy and protein administration to optimize the clinical outcome are required to fine tune current guidelines.

Abstract
Severe traumatic brain injury ranks among the most common causes of death in young adults in western countries. Severe traumatic brain injury is typically followed by a pronounced pathophysiological cascade that accounts for many deaths. The aim of intensive care medicine after traumatic brain injury is to minimize and to control the consequences of this potentially fatal cascade. The avoidance of hypoxemia, arterial hypotension, intracranial hypertension, hyperthermia, hyperglycemia, hypoglycemia and thromboembolic complications is essential in preventing this cascade. The effect of nutrition has been rather underestimated as a means of improving the outcome after traumatic brain injury. Nutrition should be started within the first 24 h after trauma. Enteral, wherever applicable, should be the route of administration of nutrition. Enteral administration of the whole calculated calorie requirement on day 1 after trauma, if possible, lowers the infection and overall complication rates. The present review gives an update of a practical approach to nutrition in traumatic brain injury.

Abstract
Nutritional therapy has an important role in the management of patient with severe acute pancreatitis. This article reviews the endoscopist’s approach to manage nutrition in such cases. Enteral feeding has been clearly validated as the preferred route of feeding, and should be started early on admission. Parenteral nutrition should be reserved for patients with contraindications to enteral feeding such as small bowel obstruction. Moreover, nasogastric feeding is safe and as effective as nasojejunal feeding. If a prolonged course of enteral feeding (> 30 d) is required, endoscopic placement of feeding gastrostomy or jejunostomy tubes should be considered.

Abstract
BACKGROUND Early enteral nutrition (EN) in patients receiving mechanical ventilation commonly has been advocated, based mainly on studies conducted in mixed populations of trauma and surgery patients. In this study, ventilator-associated pneumonia rates and outcomes were compared in mechanically ventilated medical intensive care unit (ICU) patients receiving enteral versus parenteral nutrition. METHODS Patients fulfilling inclusion criteria between February 1, 2004, and January 31, 2006, were included. Patients were randomized to enteral or parenteral nutrition (PN) within 48 hours of intubation. Development of ventilator-associated pneumonia, assessment as to whether day feeding goal was attained, duration of mechanical ventilation, ICU and hospital length of stay (LOS), and mortality rates were recorded. RESULTS Of 249 consecutive patients receiving mechanical ventilation, 71 patients were included. Thirty (42.3%) patients received EN, and 41 (57.7%) received PN. There was no difference between groups for age, sex, body mass index, and scores on the Acute Physiology and Chronic Health Evaluation II. Ventilator-associated pneumonia rate, ICU and hospital LOS, and mortality rates were similar for both groups. In the parenterally fed group, duration of mechanical ventilation was longer (p = .023), but the feeding goal was attained earlier (p = .012). CONCLUSIONS In mechanically ventilated patients in the medical ICU, ventilator-associated pneumonia rates, ICU and hospital lengths of stay, and ICU and hospital mortality rates of patients receiving PN are not significantly different than those in patients receiving EN, and feeding goals can more effectively be attained by PN. Yet, duration of mechanical ventilation is slightly longer in patients receiving PN.

Abstract
The physiological response to blood glucose elevation is the pancreatic release of insulin, which blocks hepatic glucose production and release, and stimulates glucose uptake and storage in insulin-dependent tissues. When this first regulatory level is overwhelmed (that is, by exogenous glucose supplementation), persistent hyperglycaemia occurs with intricate consequences related to the glucose acting as a metabolic substrate and as an intracellular mediator. It is thus very important to unravel the glucose metabolic pathways that come into play during stress as well as the consequences of these on cellular functions. During acute injuries, activation of serial hormonal and humoral responses inducing hyperglycaemia is called the 'stress response'. Central activation of the nervous system and of the neuroendocrine axes is involved, releasing hormones that in most cases act to worsen the hyperglycaemia. These hormones in turn induce profound modifications of the inflammatory response, such as cytokine and mediator profiles. The hallmarks of stress-induced hyperglycaemia include 'insulin resistance' associated with an increase in hepatic glucose output and insufficient release of insulin with regard to glycaemia. Although both acute and chronic hyperglycaemia may induce deleterious effects on cells and organs, the initial acute endogenous hyperglycaemia appears to be adaptive. This acute hyperglycaemia participates in the maintenance of an adequate inflammatory response and consequently should not be treated aggressively. Hyperglycaemia induced by an exogenous glucose supply may, in turn, amplify the inflammatory response such that it becomes a disproportionate response. Since chronic exposure to glucose metabolites, as encountered in diabetes, induces adverse effects, the proper roles of these metabolites during acute conditions need further elucidation.

Abstract
The neuroendocrine response to critical illness is key to the maintenance of homeostasis. Many of the drugs administered routinely in the intensive care unit significantly impact the neuroendocrine system. These agents can disrupt the hypothalamic-pituitary-adrenal axis, cause thyroid abnormalities, and result in dysglycemia. Herein, we review major drug-induced endocrine disorders and highlight some of the controversies that remain in this area. We also discuss some of the more rare drug-induced syndromes that have been described in the intensive care unit. Drugs that may result in an intensive care unit admission secondary to an endocrine-related adverse event are also included. Unfortunately, very few studies have systematically addressed drug-induced endocrine disorders in the critically ill. Timely identification and appropriate management of drug-induced endocrine adverse events may potentially improve outcomes in the critically ill. However, more research is needed to fully understand the impact of medications on endocrine function in the intensive care unit.

Abstract
PURPOSE OF REVIEW In the setting of ICU, the characteristics of patients have changed during the last decade. Patients are older, frequently overweight or obese, present with more chronic diseases and undernutrition. These conditions are characterized by reduced muscle mass and vulnerable homeostasis. This review sustains the hypothesis that an early and optimal nutritional support, combining enteral and parenteral nutrition, could improve the clinical outcome of ICU patients. RECENT FINDINGS The combination of stress and undernutrition observed in the ICUs is associated with negative energy balance, which leads to lean body mass loss. Catabolism of lean body mass has been repeatedly associated with a worsening of the clinical outcome, increased length of hospital stay, recovery and healthcare costs. Early enteral nutrition is the recommended feeding route in ICU patients, but it is often unable to fully cover the nutritional needs. Parenteral nutrition is recommended if enteral nutrition is not feasible. SUMMARY It is hypothesized that supplemental parenteral nutrition, together with insufficient enteral nutrition, could optimize the nutritional therapy by preventing the onset of early energy deficiency, and thus, could allow to reduce the side-effects of undernutrition and promote better chances of recovery after the ICU stay.

Abstract
Clinical trials conducted in the latter part of the past millennium suggested that bleeding from gastric stress ulceration was an important cause of morbidity and mortality in intensive care unit (ICU) patients and that treatment with acid-suppressive therapy reduced the risk of clinically significant bleeding. Stress ulcer prophylaxis therefore became regarded as the standard of care in all ICU patients. However, more recent clinical trials have demonstrated that the risk of clinically significant bleeding is extremely low (about 1%) and not altered by the use of acid-suppressive therapy. Furthermore, a critical review of the “historical” clinical trials, as well as the data from experimental and more recent clinical trials, suggests that enteral feeding (gastric) is at least as effective as acid-suppressive therapy in the prevention of gastric stress ulceration and is the prophylactic measure of choice in most ICU patients.

Abstract
BACKGROUND Following publication of the Leuven Intensive Insulin Therapy Trial in 2001, tight glycemic control became the standard of care in ICUs around the world. Recent studies suggest that this approach may be flawed. The goal of this systematic review was to determine the benefits and risks of tight glycemic control in ICU patients and to explain the differences in outcomes among reported trials. METHODS Prospective, randomized controlled clinical trials (RCTs) that studied the impact of tight glycemic control (blood glucose 80-110 mg/dL) on mortality in ICU patients were identified through a search of MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews, and a citation review of relevant primary and review articles. Data were abstracted on study design, study size, and patient characteristics, as well as on the mean (or median) and SD of the ICU blood glucose level, mean daily dose of insulin administered, average daily caloric intake, percentage of calories given intravenously (parenteral nutrition), incidence of hypoglycemia, need for dialysis, and 28-day/hospital mortality. Metaanalytic techniques were used to analyze the data; subgroup analysis and metaregression were used to explain differences in the treatment effect. RESULTS We identified seven RCT studies that included 11,425 patients. Overall, tight glycemic control did not reduce the 28-day mortality (odds ratio [OR] 0.95; 95% CI, 0.87-1.05), the incidence of blood stream infections (OR 1.04; 95% CI, 0.93-1.17), or the requirement for renal replacement therapy (OR 1.01; 95% CI, 0.89-1.13). The incidence of hypoglycemia was significantly higher in patients randomized to tight glycemic control (OR 7.7; 95% CI, 6.0-9.9; P < .001). Metaregression demonstrated a significant relationship between the treatment effect (28-day mortality) and the proportion of calories provided parenterally (P = .005). This suggests that the difference in outcome between the two Leuven Intensive Insulin Therapy Trials and the subsequent trials could be related to the use of parenteral nutrition. When the two Leuven Intensive Insulin Therapy Trials were excluded from the metaanalysis, mortality was lower in the control patients (OR 0.90; 95% CI, 0.81-0.99; P = .04; I(2) = 0%). CONCLUSIONS There is no evidence to support the use of intensive insulin therapy in general medical-surgical ICU patients who are fed according to current guidelines. Tight glycemic control is associated with a high incidence of hypoglycemia and an increased risk of death in patients not receiving parenteral nutrition.

Abstract
Until recently, stress hyperglycemia was considered to be a beneficial adaptive response, with raised blood glucose providing a ready source of fuel for the brain, skeletal muscle, heart and other vital organs at a time of increased metabolic demand. Following the Leuven Intensive Insulin Therapy Trial in 2001, tight glycemic control became rapidly adopted as the standard of care in intensive care units (ICU’s) throughout the world. However, four randomized controlled studies and the recently published NICE-SUGAR study have subsequently been unable to replicate the findings of the Leuven Intensive Insulin Therapy Trial. This paper offers an explanation for these discordant findings, and provides a practical approach to glucose control in the ICU.

Abstract
Compared to enteral or hypocaloric oral nutrition, the use of PN (parenteral nutrition) is not associated with increased mortality, overall frequency of complications, or longer length of hospital stay (LOS). The risk of PN complications (e.g. refeeding-syndrome, hyperglycaemia, bone demineralisation, catheter infections) can be minimised by carefully monitoring patients and the use of nutrition support teams particularly during long-term PN. Occuring complications are e.g. the refeeding-syndrome in patients suffering from severe malnutrition with the initiation of refeeding or metabolic, hypertriglyceridemia, hyperglycaemia, osteomalacia and osteoporosis, and hepatic complications including fatty liver, non-alcoholic fatty liver disease, cholestasis, cholecystitis, and cholelithiasis. Efficient monitoring in all types of PN can result in reduced PN-associated complications and reduced costs. Water and electrolyte balance, blood sugar, and cardiovascular function should regularly be monitored during PN. Regular checks of serum electrolytes and triglycerides as well as additional monitoring measures are necessary in patients with altered renal function, electrolyte-free substrate intake, lipid infusions, and in intensive care patients. The metabolic monitoring of patients under long-term PN should be carried out according to standardised procedures. Monitoring metabolic determinants of bone metabolism is particularly important in patients receiving long-term PN. Markers of intermediary, electrolyte and trace element metabolism require regular checks.

Abstract
PURPOSE OF REVIEW Patients with acute pancreatitis have traditionally been treated with 'bowel rest'. Recent data, however, suggest that this approach may be associated with increased morbidity and mortality. This paper reviews evolving concepts in the nutritional management of patients with acute pancreatitis. RECENT FINDINGS Both experimental and clinical data strongly support the concept that enteral nutrition started within 24 h of admission to hospital reduces complications, length of hospital stay and mortality in patients with acute pancreatitis. Clinical trials suggest that both gastric and jejunal tube feeding is well tolerated in patients with severe pancreatitis. Although there is limited data for the optimal type of enteral feed, a semielemental formula with omega-3 fatty acids is recommended. On the basis of current evidence, immune modulating formulas with added arginine and probiotics are not recommended. SUMMARY Nutritional support should be viewed as an active therapeutic intervention that improves the outcome of patients with acute pancreatitis. Enteral nutrition should begin within 24 h after admission and following the initial period of volume resuscitation and control of nausea and pain. Patients with mild acute pancreatitis should be started on a low-fat oral diet. In patients with severe acute pancreatitis, enteral nutrition may be provided by the gastric or jejunal route.

Abstract
Background/Objectives: To measure reactive oxidant production and the decline in antioxidant potential in commercially available, irradiated parenteral nutrition (PN) solutions and the effect that these have on oxidant production in patients in the intensive care unit. Subjects and Methods: Vitamin E and malondialdehyde in irradiated and nonirradiated commercially available, PN solutions were measured. The PBN (α-phenyl-n-test-butylnitrone (PBN) spin trap was used to measure free radicals and TEMPOL (2,2,6,6-tetramethyl-4-hydroxy-piperidine-oxyl) was used to assess antioxidant capacity. The irradiated PN was administered (as per unit protocol) to 10 patients with gut failure and plasma and urinary isoprostanes and interleukin-6 (IL-6) were measured 1 hour preadministration, at the time of, and 1 and 2 hours postadministration of PN. Results: Irradiation reduced vitamin E significantly (P < .0025). Malondialdehyde products were present in both samples, but more so in irradiated samples (P < .0001), as were free radicals measured by PBN spin trapping. Irradiated samples had a higher scavenging capacity of TEMPOL free radical due to depletion of antioxidants in irradiated samples. Urinary isoprostanes increased at time 2 by 6.3 units relative to time 0 and by 5.23 units relative to time 1(Friedman ANOVA: P < .01413). Conclusions: Lipid hydroperoxides are formed in PN solutions and increase further following irradiation. This is associated with a significant reduction in vitamin E and antioxidant potential. The increase in urinary isoprostanes indicates a potentially proinflammatory effect of irradiated PN.

Abstract
The advent of total parenteral nutrition in the late 1960s meant that no situation remained in which a patient could not be fed. Unfortunately, total parenteral nutrition was complicated by serious infective and metabolic side effects that undermined the beneficial effects of nutrient repletion. Consequently, creative ways of restoring upper gut function were designed, based on semielemental diets and novel feeding tube systems. The employment of specific protocols and acceptance of increased gastric residual volumes has allowed most patients in intensive care to be fed safely and early by nasogastric tube. However, nasogastric feeding is unsuitable for patients with severely compromised gastric emptying owing to partial obstruction or ileus. Such patients require postpyloric tube placement with simultaneous gastric decompression via double-lumen nasogastric decompression and jejunal feeding tubes. These tubes can be placed endoscopically 40-60 cm past the ligament of Treitz to enable feeding without pancreatic stimulation. In patients whose disorders last more than 4 weeks, tubes should be repositioned percutaneously, by endoscopic, open or laparoscopic surgery. Together, the advances in enteral access have improved patients' outcomes and led to a 70-90% reduction in the demand for total parenteral nutrition.

Abstract
PURPOSE OF REVIEW Current recommendations suggest starting enteral feeding as soon as possible whenever the gastrointestinal tract is functioning. The disadvantage of enteral support is that insufficient energy and protein coverage can occur. This review focuses on some recent findings regarding the nutritional support of critically ill patients and evaluates the data presented. RECENT FINDINGS An increasing nutritional deficit during a long ICU stay is associated with increased morbidity (infection rate, wound healing, mechanical ventilation, length of stay, duration of recovery), and costs. Evidence shows that enteral nutrition can result in underfeeding and that nutritional goals are frequently reached only after 1 week. Contrary to former beliefs, recent meta-analyses of ICU studies showed that parenteral nutrition is not related to a surplus mortality and may even be associated with improved survival. SUMMARY Early enteral nutrition is recommended for critically ill patients. Supplemental parenteral nutrition combined with enteral nutrition can be considered to cover the energy and protein targets when enteral nutrition alone fails to achieve the caloric goal. Whether such a combined nutritional support provides additional benefit on the overall outcome has to be proven in further studies on clinical outcome, including physical and cognitive functioning, quality of life, cost-effectiveness, and cost-utility.

Abstract
Enteral nutrition (EN) gives a legacy of under nutrition in intensive care patients but few appreciate that parenteral nutrition (PN) carries the other risk of overfeeding if used injudiciously. Over-feeding presents a significant metabolic stress but tight glycaemic control is now masking the traditional warning signs and does not on its own negate the need to give patients the right amount at the right time.

Abstract
PURPOSE OF REVIEW Today, early nutrition support is considered standard care in most ICUs. The recommended method is the enteral route, although there is only minor evidence for this. Often inadequate delivery of energy and a cumulative energy deficit are implied. The purpose of this paper is to evaluate the indication for early enteral nutrition or immunonutrition and to discuss the application of additional parenteral nutrition. RECENT FINDINGS The indication for early enteral nutrition is also supported by guidelines for enteral nutrition recently published by the European Society for Clinical Nutrition and Metabolism. Some more recent results strengthen the indication for a special formula in acute respiratory distress syndrome and septic patients. A recent metaanalysis has shown that parenteral nutrition is superior to delayed enteral nutrition. Additional parenteral nutrition thus seems to be the way to avoid cumulative energy deficit associated with insufficient or no enteral nutrition. SUMMARY Early enteral nutrition is recommended for critically ill patients, with special formulas indicated in specific subgroups of patients. If enteral nutrition is insufficient or fails, parenteral nutrition should be instituted, respecting the often reduced demand for exogenous substrates in critically ill patients.

Abstract
Acute pancreatitis is a clinical syndrome defined by a discrete episode of abdominal pain and elevations in serum enzyme levels. Seventy-five percent to 85% of all pancreatic episodes are considered mild and self-limiting and do not require intervention with nutrition support. Considering the significant risk of malnutrition in moderate to severe forms of pancreatic injury, enteral nutrition has more recently been documented in its benefit as an adjunct to management. In addition, it may play a role in obviating the systemic inflammatory response syndrome and in modifying the course of the disease. This paper reviews practical considerations in feeding patients with severe acute pancreatitis, including discussion of gastric versus post-pyloric feeding, choice of enteral product, and relative role and optimization of parenteral nutrition support.

Abstract
INTRODUCTION Liver dysfunction associated with artificial nutrition in critically ill patients is a complication that seems to be frequent, but it has not been assessed previously in a large cohort of critically ill patients. METHODS We conducted a prospective cohort study of incidence in 40 intensive care units. Different liver dysfunction patterns were defined: (a) cholestasis: alkaline phosphatase of more than 280 IU/l, gamma-glutamyl-transferase of more than 50 IU/l, or bilirubin of more than 1.2 mg/dl; (b) liver necrosis: aspartate aminotransferase of more than 40 IU/l or alanine aminotransferase of more than 42 IU/l, plus bilirubin of more than 1.2 mg/dl or international normalized ratio of more than 1.4; and (c) mixed pattern: alkaline phosphatase of more than 280 IU/l or gamma-glutamyl-transferase of more than 50 IU/l, plus aspartate aminotransferase of more than 40 IU/l or alanine aminotransferase of more than 42 IU/l. RESULTS Seven hundred and twenty-five of 3,409 patients received artificial nutrition: 303 received total parenteral nutrition (TPN) and 422 received enteral nutrition (EN). Twenty-three percent of patients developed liver dysfunction: 30% in the TPN group and 18% in the EN group. The univariate analysis showed an association between liver dysfunction and TPN (p < 0.001), Multiple Organ Dysfunction Score on admission (p < 0.001), sepsis (p < 0.001), early use of artificial nutrition (p < 0.03), and malnutrition (p < 0.01). In the multivariate analysis, liver dysfunction was associated with TPN (p < 0.001), sepsis (p < 0.02), early use of artificial nutrition (p < 0.03), and calculated energy requirements of more than 25 kcal/kg per day (p < 0.05). CONCLUSION TPN, sepsis, and excessive calculated energy requirements appear as risk factors for developing liver dysfunction. Septic critically ill patients should not be fed with excessive caloric amounts, particularly when TPN is employed. Administering artificial nutrition in the first 24 hours after admission seems to have a protective effect.

Abstract
Critically ill patients who depend on intensive care for more than a few days reveal profound erosion of lean body mass, which is thought to contribute to high morbidity and mortality. Despite a shortfall of evidence that supplemental feeding actually alters clinical outcome of these life-threatening disease states, this observation evoked an almost universal, albeit often inappropriate, use of nutritional support (NS) in the critically ill, administered via the parenteral or the enteral route. Lack of knowledge and overenthusiasm subsequently resulted in complications associated with both parenteral nutrition (PN) and enteral nutrition (EN), which led to the standing controversy over which should be preferred. With time, however, it became clear that EN and PN are not mutually exclusive and that critically ill patients requiring NS should be fed according to the functional status of the gastrointestinal tract. In addition, tight blood glucose control with insulin is advised in fed critically ill patients because overall metabolic control appears to surpass any outcome benefit attributed to the route of feeding. Recently, various special nutritional formulas have been suggested to prevent or treat multiorgan failure in the critically ill, among other pathways via modulation of immune function. Although special nutritional formulas may be promising in a variety of clinical settings, based on currently available data, these cannot be recommended for routine use in critically ill patients.

Abstract
PURPOSE OF REVIEW The gastrointestinal tract plays a major role in critical illness. We will review four common problem areas pertaining to the gut and abdominal compartment that intensivists managing critically ill patients must deal with on an everyday basis. RECENT FINDINGS In the area of enteral nutrition, there have been concerns that early feeding in hemodynamically unstable patients might cause bowel infarction by increasing the gut oxygen consumption beyond splanchnic oxygen delivery. The most recent data suggest that early enteral feeding, even when patients are receiving vasopressors, is safe and may actually protect the gut by increasing gut perfusion. Although there are no new treatments for ileus, in most critically ill patients ileus primarily affects the stomach and large intestine, and most patients who are diagnosed with ileus may still be fed enterally as long as they are fed distal to the stomach. Diarrhea is a common occurrence in the intensive care unit, particularly in patients who are being fed enterally. Of most import is the realization that Clostridium difficile infection is ubiquitous and must be considered in virtually every case of diarrhea. Abdominal compartment syndrome is usually a result of shock, and its resuscitation with increased intra-abdominal pressure results in many untoward hemodynamic and respiratory events. Early recognition and treatment seem to be associated with improved outcome. SUMMARY Continued progress in the areas of optimal nutritional support, understanding the implications of alterations in immune function of the gut, and the avoidance of such morbid complications as abdominal compartment syndrome are expected.

Abstract
PURPOSE OF REVIEW Nutrition support when applied appropriately, can improve clinical outcomes, particularly the incidence of infections. The Canadian Clinical Practice Guidelines for Nutrition Support, published in October 2003, summarized the evidence on nutrition support in the critically ill patient and provided recommendations aimed at maximizing the benefits of nutrition support while minimizing the risks. The purpose of this review is to highlight recent advances in nutrition research in critically ill adult patients, particularly with respect to minimizing infection. The newly published data will be used to update the Canadian Clinical Practice Guidelines. RECENT FINDINGS Recent studies have confirmed that the use of enteral nutrition versus parenteral nutrition, early initiation of enteral nutrition, use of enteral and parenteral glutamine and intensive insulin therapy are all associated with reduced infectious morbidity in critically ill patients. A recent meta-analysis suggests that antioxidant supplementation is associated with no improvement in infectious complications, but an increase in survival. The recommendations from the Canadian Clinical Practice Guidelines for Nutrition Support have been updated based on the data from these recent trials. SUMMARY This review provides insights into the results of recent randomized trials on nutrition support in critically ill patients. The Canadian Clinical Practice Guidelines for nutrition support help intensive care unit clinicians to keep abreast of emerging evidence and the impact of nutrition support practices on outcomes such as infections.

Abstract
Systematic undernutrition of intensive care unit patients is common and neglected. Is this inevitable or can better routines and protocols make a difference? The necessity of feeding may be regarded as self-evident, but more evidence is obviously needed to strengthen this issue. In rich countries it should be a human right not to be hungry.
