Trisha Fuhrman, MS, RDN, LD, FAND, FASPEN [email protected] Chair of DPS CNW17 Orlando Marisa Mozer, MS, RD, LDN, CNSC Senior Clinical Dietitian Rush University Medical Center Why did you become interested in nutrition support? I became interested in nutrition support because I saw the impact of nutrition in improving a patient’s tolerance to their cancer treatment. Nutrition support should be considered for all cancer patients who are malnourished, or for those who are receiving treatment which could potentially impair their ability to eat and lead to malnutrition. In my experience, there have been several cases where nutrition support has been an integral part of the treatment process in saving a patient’s life following aggressive treatment. What is your favorite aspect of being a member of A.S.P.E.N.? My favorite part of being a member of A.S.P.E.N is the abundant number of evidenced based resources that are available, and the ability to connect with other nutrition support clinicians. A.S.P.E.N. is a great way to interact with other clinicians in your area of practice, as well as areas you are just beginning to be exposed to. Tell us about your career pathway and how you got to where you are now? Initially, I thought I wanted to work in childhood obesity. After completing my inpatient oncology rotation as part of my internship at Rush University Medical Center in Chicago, I knew my career path was going to be different. I quickly realized my love for the oncology population, and knew that I was making a difference in their lives. These patients have trust and respect for oncology dietitians because they know they need the help with symptom Dietetics Practice Section Newsletter management and preserving lean body mass. This led me to a position working as the lead oncology dietitian, specifically working with the inpatient hematology / bone marrow transplant and oncology teams, as well as the outpatient radiation oncology population at Rush. What is your proudest moment as a nutrition support dietitian? My proudest moment as a nutrition support dietitian is gaining the respect of the hematology and stem cell transplant teams, ultimately leading to approval for routine placements of nasogastric feeding tubes in hematology and stem cell transplant patients – a practice that rarely occurred at our institution. The team truly values nutrition in recovery, and for many patients, nutrition support is crucial to their treatment and recovery. What advice do you have for dietitians entering the field of nutrition support? Although nutrition support is often overlooked among cancer patients, being well versed in the evidence supporting its use will allow the multidisciplinary team to support you, ultimately leading to improved patient outcomes. What do you do to relax? Exercise – nothing like a good spin class to get the adrenaline flowing and motivation to keep focused! 2 Call for CNW17 Session Reporters Volunteers Needed! Will you be attending CNW 2017 in Orlando, either in person or virtually? Would you be willing to summarize the content of one or two sessions you attend? This is YOUR chance to get involved in your section! Reporting on a session you attend provides you the opportunity to reflect on the content you heard, follow up by reading some of the papers referenced, and summarize your final thoughts on the information presented. This process helps you retain the information and incorporate it into your own clinical practice knowledge and skill set. It also provides an informative and quick outline of the topic to share with fellow clinicians who may have been unable to attend the session. Writing a summary is an easy way to get more involved in the Dietetics Practice Section and to share your skills, while enhancing our profession as a whole. Please consider being a Volunteer Reporter at this year’s conference. To volunteer, contact Jessica at [email protected] for more information and to sign up for your favorite sessions.

Stauffer-Engelbrecht, MS, RD, CSR, LD, CNSC Cancer Treatment Centers of America Tulsa, Oklahoma The physical examination and skills lab post graduate course provided a great opportunity for CNW attendees to learn about and practice performing a physical examination with experts present for evaluation and critique. Current evidence and consensus suggests that performing a physical examination with a focus on body fat, muscle mass, fluid accumulation, and functional performance is a necessary part of the nutrition assessment and for determining presence and degree of malnutrition.1 This post graduate course showcased skills necessary for a complete nutrition-focused physical examination. The Dietitians in Nutrition Support DPG Nutrition-Focused Physical Exam video was shown. The video was a complete head to toe nutrition-focused physical exam performed by an RDN with an actor/patient in a hospital setting.2 Following the general session, attendees were divided into smaller groups to attend seven breakout training sessions. These break-out trainings provided history, evidence, and an overview of a specific part of the nutritionfocused physical exam. Tools that might be used by the RDN during the nutrition-focused physical exam were highlighted and available for hands-on use. Attendees had an opportunity to practice and ask questions of the experts about each learning point before moving on to the next training session. Understanding Hemodynamics in the ICU and the Relationship to Nutrition Dr. Oltermann provided a concise review of basic hemodynamics in the intensive care unit to give a better understanding of interpreting findings and be able to better participate in a multidisciplinary team.

We’ve gathered a few interesting Orlando facts you may not have known: Orlando has 100 lakes, many of which are the result of sinkholes. Rose Lake, an infamous lake formed from a sinkhole in Winter Park, was mentioned in HBO’s "The Sopranos" as a good place to hide bodies. If you’re flying into CNW, you’ll have a birds eye view. Lake Eola (home of the famous fountain on page 2) is actually a giant sinkhole and reaches 80 feet deep. Take a stroll around this downtown Orlando lake and visit the over 50 swans in residence. Orlando is home to a strong local food movement, James Beard winning chefs, a huge food truck scene, and the first free-standing seed to plate school nutrition curriculum program in the country! Orlando City is the Major League Soccer team and will begin this season in a brand new stadium in downtown Orlando. Orlando businessman Dr. Philip Phillips once owned 5,000 acres of citrus, perfected the canned orange juice process and sold his company to Minute Maid in 1954 for $50 million. Florida is both the Sunshine State and the Lightning Capital of America. In 1957, the famous beat writer Jack Kerouac wrote “On the Road” in Orlando. The largest collection of Tiffany glass in the world can be found at the Morse Museum of American Art in Winter Park.

Algorithms for determining the best treatment approach for each condition were provided, and attendees were able to touch and feel several different wound care products. Joseph Boullata and Linda Lord shared best practices for preventing feeding tube obstructions and recommended methods for unclogging a feeding tube. Key recommendations included at least 30ml water flushes every 4 hours during continuous feedings and before and after intermittent feedings and residual volume checks. They emphasized the importance se- lecting the best formulation of drug and proper drug preparation before administration. Fruit juices and carbonated beverages were discouraged and activated pancreatic enzyme solutions were recommended for unclogging feeding tubes. In addition to the lecture and hands-on sessions, attendees were able to visit the GEDSA (Global Enteral Device Supplier Association) table and examine the new ENFit connectors, feeding tubes, and syringes. Attendees were encouraged to visit the Stay Connected website (http://stayconnected.org) to keep updated on the timeline for implementation.

The difference was statistically significant, but possibly not clinical significant. Bliss concluded that premixed PN may offer some advantages over custom PN except in high risk patient populations. M. Petrea Cober, PharmD, reviewed the Pros and Cons of repackaging intravenous fat emulsions (IVFE) specifically in the neonatal population since NICU’s almost exclusively use 2-in-1 PN solutions due to stability of emulsions with < 2% lipid, increased neonatal calcium/phosphorus needs, and limited venous access. Cober noted that commercial IVFE are available in volumes of 100mL in the US which is significantly greater than a neonate’s need. Cober also mentioned repackaging IVFE improves utilization of limited resources given recent lipid shortage. Cober noted common NICU IVFE medication errors, such as resetting the infusion rate for IVFE, rates of PN and IVFE being switched, and IVFE being infused too quickly. Cober then reviewed ASPEN recommendations against repacking IVFE into syringes, suggesting drawn-down IVFE units. Ultimately, Cober encouraged discussion with companies to produce smaller packages of IVFE and reevaluating each facility’s process for administering IVFE. References: Erdman, et al.

This involves placing the majority of the responsibility on the pediatric provider in helping the patient learn to be responsible for their care. In the diabetic population, transitioning from pediatric to adult care led to a 2.5 times higher HgbA1c. There are vast differences in pediatric versus adult care delivery systems. Pediatric systems are family based care with multi-disciplinary teams, whereas adult care is patient based rather than family based. Other disciplines are not necessarily at each clinic visit. Studies have shown patients have difficulty with the transition. They may not have a good understanding of their disease state, their prior treatment history and overall plans, etc. Families have often been over involved in patient care and that transition to the patient taking full responsibility is difficult. It is recommended to start this transition early. Checklists Dietetics Practice Section Newsletter may be helpful as the patient, family, and medical team move through the transition process.

Patients are often resistant to changing their care providers; in fact some adults are asking to be covered by pediatric teams. There is a no age limit in the clinic, and in the hospital surgery can be performed on anyone 35 and under. Each center needs to have their own solutions, depending on the adult resources in their own area. Making the Case for Transfer to an Adult IF Programmorphed the topic to: Perspectives on Transfer to an Adult IR Program Kishore Iyer, MD, Pediatric Surgeon, Mt. Sinai, New York Dr Iyer acknowledged the help and research of Dr. Rachel Annunziato who has many articles on this topic. Some are referenced below along with his main discussion points: Dr. Iyer works with both pediatric and adult intestinal failure patients Transition is a process where the patient takes over his care, whereas transfer is just a moment in time. In other fields such as congenital heart disease, diabetes, and transplant, we have seen a marked loss of compliance after transferring centers. Tacrolimus levels were much higher after transfer from a pediatric to adult transplant center, suggesting problems with compliance, even 2 years later.

Will nutrition have the same impact in these two types of patients? In order to determine which patient will benefit the most, a conceptual model was developed for nutrition risk assessment in the critically ill patient. The true nutritional state of a critically ill individual would include their acute and chronic degree of nourishment and inflammation. The degree of acute inflammation could be measured by interleukine 6 (IL6), C-reactive protein (CRP), Dr. Heyland shared that after working for 25 and procalcitonin (PCT). Chronic inflammayears in Critical Care Nutrition, he has found tion could be reflected by comorbidities. that ICU patients are not created equal; Acute starvation could be determined from a therefore we could not expect that the impact diet or intake history, and chronic undernourof nutrition therapy can be the same across ishment might be diagnosed by obtaining a all patients.

For example, a 34Outcomes research has started to turn from survivorship year-old male athlete with a BMI of 35 involved in a motor to quality of life and functional status. The EDEN trial2 vehicle accident with a mild head injury and a fractured right leg is not the same as a 79-year-old woman with the Continued on next page Dietetics Practice Section Newsletter 10 Figure 1 was the first RCT that started to systematically look at the survivorship issues in critically ill patients, such as physical and cognitive assessments after one year. Patients who were fully fed had better outcomes in their 6 minute walk distance and 4 minute timed walk, in comparison to those who were not. Even though the results were not statistically significant, there was a clinically relevant improvement. This data is comparable to a sub study of the REDOXS trial, in which patients with nutritional adequacy during the first eight days of mechanical ventilation in the ICU were assessed using the Short-Form 36 Health Survey questionnaire at 3 and 6 months post ICU admission. Table 1 Increased nutritional adequacy in the ICU was associated with better scores - indicating patients who had received adequate nutrition had a faster recovery. As we move forward and think about the survivors’ journey, it is necessary to develop a framework for evaluating the impact of nutrition and exercise interventions in survivors of critical illness. This will enable us to standardize across time and studies; beginning with defining a baseline status that could be compared with the same parameters after acute illness. It is necessary to determine the pathology and impairment of critical illness, the activity limitations within the hospital, the restriction at the patient’s home environment, and finally assessing quality of life.3 There has been a lot of research in glutamine in the critical ill context. In a RCT conducted by Heyland et al, glutamine supplementation was given to the sickest patients.4 The result was increased mortality with supplementation. When the plasma glutamine levels were measured, 1/3 of the patients were deficient, 1/3 were normal, and 1/3 had super elevated levels of plasma glutamine. Other work has shown that both low and high levels of glutamine increase mortality. It appears that the best approach is to know the plasma levels of glutamine before supplementing. In conclusion, not all ICU patients are the same; it is necessary to have new approaches to determine which patients or subpopulations will benefit the most from nutrition therapy. This will have important implications for clinical practice, design of research trials, and interpretation of existing studies. References 1. Arabi YM, Aldawood AS, Haddad SH, et al.

The truth is that today hypermetabolism is not what is used to be. The story begins with Sir David Cuthbertson, in his famous paper1 from 1932 in which he related increased protein catabolism with increased energy expenditure. The next landmark paper was from Calving Long2 in which he showed that in different kinds of injury (major and minor burns and major and minor trauma) the energy expenditure was increased above the resting energy expenditure (REE), meanwhile the curve for starving patients was below the REE. Bistrian and Blackburn3 used a formula which multiplied the weight in pounds by 10, obtaining the total daily calories required. Hunter3 then compared this formula with the results of indirect calorimetry and the Harris Benedict equation and found fairly similar results, within 100kcal per day. As clinicians know, standard estimation equations are frequently inaccurate in today’s ICUs.4 Advances in ICU care such as synchronous ventilation, infection control, thermo-neutral environments for burn care, enhanced pain management, improved anesthesia, and superior surgical techniques could all be factors that have modified the energy needs. We now know that standard equations do not adequately predict individual REE and that actual measurements are advised for patients at risk.4 The nutritional needs of pediatric patients are different than adults because pediatric needs must account for growth. In a study of two different groups of pediatric patients (stable ventilated postoperative parental nutrition fed term neonates versus parenteral nutrition fed term neonates on extracorporeal membrane oxygenation), the measurement of the energy requirements through stable isotopes had similar mean requirements to age matched well children. Therefore, after obtaining the REE, the question is if the provision of excess calories will enhance the protein sparing effect. Providing excess calories to neonates may not improve protein balance, paradoxically it could worsen it, since it accentuates protein breakdown. The effect of surgery in premature neonatal patients with narcotic anesthesia does not increase the REE. There is only a small incremental increase during the first few hours post-op and needs quickly return to pre-surgical levels. The best predictor of postoperative REE is preoperative REE; nevertheless there is a paradox because in the convalescence phase of illness, when neonates are removed from the ventilator, the difficult work of breathing Dietetics Practice Section Newsletter increases the REE. Does the type of calorie have an effect on protein sparing? The ideal ratio of fat to carbohydrate is unknown in critically ill children. In general, fat should be limited to <40% of the caloric needs. Glucose and fat both have beneficial effects on net protein balance in children. Lipid turnover is increased and stores are reduced in neonates (14% in neonates, 17% in children and 19% adults). When fat is not administered for one week, there can be biochemical evidence of fatty acid deficiency. Fatty acid deficiency can be avoided by the administration of 4% of total calories coming from fat. Potential advantages of using lipids as a caloric source include: unlike glucose lipids do not increase carbon dioxide production, lipids are dense in calories so it is possible to reduce feeding volume, and lipids decrease the need for glucose which can help reduce risk of hyperglycemia in the relatively insulin resistant child. Hyperglycemia is frequently seen in pediatric ICU patients, for example 87% of cardiac surgery patients had hyperglycemia postoperatively. Taking into consideration the van den Berghe5 study regarding tight glycemic control in ICU patients, the Boston group did a randomized prospective trial to see if controlling hyperglycemia would have beneficial effects in the pediatric patient. Tight glycemic control was achieved with a relatively low hypoglycemia rate after cardiac surgery but it did not significantly change the infection rate, mortality, length of stay, or measures of organ failure, as compared with standard care (180 mg/dl glucose or lower). Muscle protein degradation measured through urinary 3-methylhystidine/ creatinine ratio was also not altered.6,7 In summary, the energy requirements of the critically ill child are generally similar to age matched healthy children. Measuring, rather than estimating energy expenditure is recommended. It is necessary to regularly obtain basic anthropometric data and follow growth curves to determine the adequacy of nutrition support. Throughout the convalescence phase of illness, “catch up growth” should occur and careful follow up should be done. Survival is not a good outcome measure for critical ill neonates. The ultimate goal is an adequate neurocognitively intact individual. References 1. Cuthbertson D. Observations on disturbance of metabolism produced by injury to the limbs.

Protein Catabolism during Pediatric Critical Illness and Impact of Protein Delivery on Outcomes Nilesh M. Mehta, MD, DCH, Director, Critical Care Nutrition; Associate Medical Director, MSICU, Boston Children’s Hospital; Associate Professor in Anesthesia, Harvard Medical School, Boston, MA In this lecture Dr. Mehta discussed protein in critical illness; metabolism, intake, how can we measure protein metabolism, and what are the next steps in optimizing it. The history of protein is fascinating. It started in Paris with Francois Magendie (1816) who said that dogs would die if they were fed only with CHO and fat. At that time, protein was only for the rich people and for the soldiers. Jacob Berzelius (1830), in Sweden named protein based on the Greek word “protas”, which means of primary importance. Justus von Liebig (1845) from Germany and Wilbur Olin Atwater from the USA increased the estimated protein requirements to 115 grams per day for a healthy young adult working in the field. Then came the tempering effect during the 1920s, when vitamins, micronutrients, and energy gained importance once again. In 1950, the appearance of kwashiorkor in Africa brought protein back to the center of both the global and political stage. The “World Protein Gap” occured between 1950 and 1970, when the United Nations declared protein deficiency as the single most important enemy and declared the importance of adequate protein administration. The two individuals who brought protein into the ICU were Sir Dr. Cuthbertson (1942) with his description of the metabolic stress response, and Dr. Dudrick who stabilized, sterilized, and solubilized amino acids, making it possible Dietetics Practice Section Newsletter - Winter 2017 to feed ICU patients. Sir David Cuthbertson summarized his work in Lancet in 1942, with a discussion of the post-shock metabolic response (Figure 2). The human body has a double response to injury whether it is trauma, sepsis, burn, or surgery. Each of these insults drives the cytokine and the neurohormonal response, which along with the counterregulatory hormones leaves the patient in a state of insulin resistance. The result is the breakdown of endogenous substrates to release nutrients that can sustain the individual to recover from the injury. This protein breakdown from the visceral protein or the muscle mass generates amino acids that enter the amino acid pool, which can then be used for protein synthesis to make acute inflammatory proteins, heal wounds and tissue, and supply glucose as a fuel for essential organs through the gluconeogenesis pathway. Nitrogen balance has been the traditional way to measure protein; nevertheless it misses the profound interaction that is constantly going on, even in someone with normal nitrogen balance. There is a tremendous amount of turnover that is happening, which is not measured through the nitrogen balance. The window into that world is stable isotopic methods, which are amino acids labeled with C or N and/or H. C Leucine or d5 Phenylalanine are injected either as a bolus or a prime followed by a continuous infusion until steady state is reached, then blood is sampled to pick up concentrations of these tracers in the plasma pool. Next a series of equations are applied to reach a reasonable idea of the protein balance, protein synthesis, and protein breakdown. You can also use the n product enrichment method, using N15Glycine given intravenously or enterally and then measured to determine how much enrichment is niFigure 2 Continued on next page 13 trogen, urea and ammonia and hence the end product. A more sophisticated method, used in burned pediatric patients, is d5 phenylalanine. After sedating the patient, d5 phenylalanine is infused through femoral arterial and venous catheterization. After giving a prime dose and 5 hours of constant infusion of the tracer, venous and arterial blood samples are taken, and different formulas are applied with the objective of obtaining protein balance, protein synthesis, and protein breakdown. It is interesting to know that phenylalanine in the peripheral tissue does not get metabolized, so there is no oxidation going on at that level; therefore the rate of disappearance from the pool of this tag phenylalanine gives a good idea of synthesis. In pediatric burn patients, a dramatic increase in protein breakdown is observed, far more than the synthetic capabilities, and as a result, the nitrogen balance is negative for 6-9 months. After 12 months the protein breakdown severity finally declines to nearly zero. DEXA scans were also taken during this study and showed that with negative protein balance the lean body mass was eroded and muscle mass decreased.1 Deuterium, heavy water, is one of the two stabilizer isotopes of hydrogen that we have on earth. It is present in very small quantities even in tap water, and it is normally present in human body in small amounts. Deuterium can be used to determine body composition. Initially, it is necessary to measure the basal quantity in the body, then after a dose of deuterium it can be measured again to quantify the enrichment. Since deuterium is like water, it goes everywhere that water goes, so the dilution allows clinicians to calculate total body water and fat free mass with the use of the isotope ratio mass spectrometer. This technique was tested in children with short bowel syndrome; even with their poor gut function they could absorb it. An important advantage is that deuterium can be tested in the urine without needing a femoral artery and a central venous catheter. The deuterium results of body composition were compared to the DEXA scan and very similar results were found. In critically ill patients, the 15NGlycine method was used with an oral bolus. In a study of 19 patients with thoracic surgery with a median age of 13.8 years (SD 12.1-15.1), anesthesia time of 5.9 hours (SD 4.5-7.3), and surgical time of 3.7 hours (SD 2.3 - 4.7), the results showed a dramatic increase in synthesis, but also a very high breakdown, much greater than synthesis. Patients were found to be in a significant negative protein balance of 1g/kg/ day. The comparison of negative balance with different methods showed very similar results between the 24 urinary urea nitrogen balance, the N urea enrichment method, and the mean 15 N end-product enrichment methods. The problem with the stabilized isotopes studies is that it is not known how much of the breakdown is contributed by different areas, and skeletal muscle is the principle area of interest. Myosin and 3MH-Actin contain histidine residues which get post translationally modified and when this breaks down they release 3-methyl-histidine/creatinine. This compound is unique because it does not go back to the synthetic pathway, so once it starts coming in, it is always an indication of breakdown, thus knowing the percentage of protein losses originating in muscle tissue. After putting all these studies together, it seems that critically ill, surgical, and septic patients have elevated protein synthesis compared to healthy children. The protein breakdown is much more elevated, and they are all in negative protein balance compared to healthy children. So how much protein are we feeding our patients? We need to pay attention to the different steps that need to be followed: first the requirements, then how it can be translated into recommendations, the prescription, and finally the delivery. Beginning with the requirements, one of the most important methods is the Indispensable Amino Acids Oxidation (IAAO). If there is an abundance of protein in the diet, there is going to be less of the given tracer breaking down to try to create energy. So if the intake goes from zero to an increased amount of protein intake, the marker of oxidation of the essential tagged protein starts slowing down until it reaches a plateau. This is used as the average requirement estimation (EAR), to which is added two standard deviations to obtain the RDA. Table 2 shows the differences in the protein requirements estimated by EAR, the RDA, and the IAAO. The difference between the EAR and the IAAO is nearly doubled. In the international study that Dr. Mehta recently completed,2 they looked at over 1,245 mechanically ventilated patients from 59 pediatric ICUs in 15 countries and observed that a quarter of these patients at admission were already malnourished. The protein prescription on average was 1.9 g /kg/day; but over a third of these patients Continued on next page Dietetics Practice Section Newsletter 14 Table 2 (37%) had significantly lower prescriptions compared to what the requirements were. Protein delivery was 0.66 g/ kg/day. This came to a 1 g/kg/day deficit compared to what was required, what was prescribed, and what was delivered. Worldwide, the percentage of enteral protein adequacy is ~50% on day seven. As protein adequacy goes up, the odds of mortality come down. If clinicians are able of deliver even 50% of what is prescribed, mortality risk significantly drops. A study of the pediatric congenital heart disease population (J Pediatr Surg 2015 Jan;50(1):74) followed the weight for age z-scores after patient discharge from the ICU and then every three months during the first year. By 12 months, patients were doing well and their weight for age z-scores had returned to baseline. The predictors of good growth at the end of one year for these patients were patch repair versus no patch repair, low birth weight, and intake of at least 2.3 g protein/kg/day. Only those who met this goal after accounting for the other factors reached their growth potential. Optimal protein intake improves outcomes in critically ill children. Delivery options are changing the relationship with energy intake in the diet; selecting enteral or parenteral nutrition or both, considering the amino acid composition, and applying bedside best practices. The protein intake study2 showed that the factors responsible for better outcomes were early initiation of enteral nutrition, the use of post pyloric feeding, the reduction of interruption of enteral nutrition; and the most important factor was the presence of an ICU dietitian. Boston Children’s PICU uses a stepwise nurse driven algorithm for enteral nutrition. A follow up of 80 patients before and 80 after initiating the algorithm showed that in Dietetics Practice Section Newsletter - Winter 2017 days four and five before the algorithm, 50% of patients were achieving the goal, but after the implementation of the algorithm this increased to 80% or even 100% in a short period of time. Both the dietitian and the algorithm make a successful combination that improve nutrient delivery. Botran et al3 studied patients fed enteral nutrition exclusively. The patients were randomized in two groups, regular diet versus diet plus protein supplementation. The regular diet provided 1.5 g/kg/day (SD1.3-2.1) and the protein enhanced diet was 3.1g/kg/day (SD 2.6-3.4). The results showed no side effects including biochemically, but the nitrogen balance before and after in both groups improved. The supplemented group improved from -2.3 (SD -3.0 to -1.2) to 0.5 (SD-0.6 to 0.8). Even though these results are not conclusive it gives the message that this can be done safely. The traditional relationship between protein and nonprotein calories and total calories in the enteral formulas should be rethought. In a systematic review that included 9 trials, nitrogen balance was achieved only with a minimum intake of 57kcal/kg/day and 1.5g protein/kg/day.4 Particularly as we give hypocaloric feeding, we need to ensure that provision of protein does not suffer. In addition to the provision of protein and calories, another way to modulate the catabolism after pediatric burn injury is anabolic agents that could improve muscle protein synthesis, such as propranolol and beta-blockers. Body composition is the next frontier for us to address in pediatrics, since it has direct implications in the functionality of the patient. “Why critically ill patients are deprived: blame rests squarely on the shoulders of the academic leaders and clinical investigators who have allowed research on this crucial question to lapse for decades… we ourselves are not exempt from this criticism” - Hoffman and Bristian.5 References 1) Hart D, Wolf S, Micak R, Chinkes D, Ramzy P, Obeng M, Ferrando A, et al.
