[PMID: 38981799 DOI: 10.1016/j.burns.2024.05.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 05/02/2024] [Accepted: 05/20/2024] [Indexed: 07/11/2024]
Abstract
PURPOSE The standard of care for burned patients experiencing hyperglycemia associated with the hypermetabolic response is insulin therapy. Insulin treatment predisposes burn patients to hypoglycemia, which increases morbidity and mortality. Metformin has been suggested as an alternative to insulin therapy for glycemic control in burn patients given its safety profile, but further research is warranted. This study investigated whether metformin use in burn patients is associated with improved glycemic control and morbidity/mortality outcomes compared to insulin use alone. MATERIALS AND METHODS Using the TriNetX database, we conducted a retrospective study of burned patients who were administered insulin, metformin, or both within one week of injury. Demographic, comorbidity, and burn severity information were collected. Patients were categorized by treatment type, propensity score-matched, and compared for the following outcomes within 3 months: hyperglycemia, hypoglycemia, sepsis, lactic acidosis, and death. Statistical significance was set a priori at p ≤ 0.05. RESULTS The insulin cohort was at increased risk for all outcomes (all p < 0.0001) compared to the metformin cohort, and an increased risk for sepsis, lactic acidosis, and death (all p ≤ 0.0002) compared to the insulin/metformin combination cohort. When compared to the metformin cohort, the combination cohort was at increased risk for all outcomes (all p ≤ 0.0107) except death. CONCLUSIONS Treatment with metformin after burn is associated with a reduced risk of morbidity and mortality compared to insulin. The combination of insulin and metformin is no more effective in reducing the risk of hyperglycemia and hypoglycemia than insulin alone but is less effective than metformin alone.

Abstract
Malnutrition is a known concern during hospitalization for humans, dogs, and cats. The same nutrition principals to reduce the risk of malnutrition can be applied to exotic companion animal patients. However, it's important to understand that many nutritional requirements are ill defined for specific species and prudent clinical judgment is required.

Abstract
BACKGROUND Differing findings concerning outcomes for burn patients with obesity indicate additional factors at play. One possible explanation could lie in determining metabolically healthy versus unhealthy obesity, which necessitates further study. METHODS A retrospective study was conducted using the Cerner Health Facts® Database. Deidentified patient data from 2014 to 2018 with second or third-degree burn injuries were retrieved. A moderator analysis was conducted to determine if the association between increased body mass index (BMI) and mortality is moderated by baseline glucose level, a surrogate marker associated with metabolically unhealthy obesity. RESULTS The study included 4682 adult burn patients. BMI alone was not associated with higher mortality (β = 0.106, p = 0.331). Moderation analysis revealed that baseline glucose level significantly modulated the impact of BMI on burn-related obesity; patients with higher BMI and higher baseline blood glucose levels had higher mortality than those with lower baseline blood glucose levels (β = 0.277, p = 0.009). These results remained unchanged after adjusting for additional covariates (β = 0.285, p = 0.025) and inthe sensitivity analysis. CONCLUSIONS Increased baseline glucose levels indicate increased mortality in obese patients with burn injuries, emphasizing the differentiation between metabolically unhealthy versus healthy obesity.

Abstract
The deadly triad concept represented a dogma in the definition of poor outcomes and death associated with major bleeding in trauma. This model of end-stage disease was then rapidly transferred to other major bleeding scenarios. However, and notwithstanding the fact that it represented a severe scenario, the original triad fails to establish a sequence, which would be relevant when defining the objectives during the initial treatment of severe bleeding. It has been recently suggested that hypoxia and hyperglycemia should be included as isolated, determining factors in this model. Likewise, the model admits only one scenario where all the conditions shall co-exist, knowing that each one of them contributes with a different risk burden. Based on a structured review, we submit a pentad model that includes a natural pattern of events occurring with hypoxemia as the main trigger for the development of hypocalcemia, hyperglycemia, acidosis and hypothermia, as hallmarks of multiple system impairment. This severity model of major bleeding ends with coagulopathy as a result of the failure to resolve the rest of the previous components.

Abstract
Severe burns represent an important challenge for patients and medical teams. They lead to profound metabolic alterations, trigger a systemic inflammatory response, crush the immune defense, impair the function of the heart, lungs, kidneys, liver, etc. The metabolism is shifted towards a hypermetabolic state, and this situation might persist for years after the burn, having deleterious consequences for the patient's health. Severely burned patients lack energy substrates and react in order to produce and maintain augmented levels of glucose, which is the fuel "ready to use" by cells. In this paper, we discuss biological substances that induce a hyperglycemic response, concur to insulin resistance, and determine cell disturbance after a severe burn. We also focus on the most effective agents that provide pharmacological modulations of the changes in glucose metabolism.

Abstract
The past one hundred years have seen tremendous improvements in burn care, allowing for decreased morbidity and mortality of this pathology. The more prominent advancements occurred in the period spanning 1930-1980; notably burn resuscitation, early tangential excision, and use of topical antibiotic dressings; and are well documented in burn literature. This article explores the advancements of the past 40 years and the areas of burn management that are presently topics of active discussion and research.

Abstract
INTRODUCTION A >25% increase in daily insulin dosing is suggestive of possible sepsis in burn patients, however, no conclusive evidence is available regarding the time point at which insulin dosing begins to increase. The purpose of this study is to determine the exact time point at which the insulin requirement increases among non-diabetic burn patients with sepsis. METHODS A retrospective chart review in non-diabetic burn patients with ≥20% total body surface area burned (TBSA) during 2010-2018 who received a blood culture for suspected sepsis. Absolute insulin dosing at intervals (0, 24, 48, 72, and 96 h prior to blood culture) were Box-Cox transformed and compared vs.-96 h reference using mixed-effects models accounting for within-patient dependencies. RESULTS Fifty-eight patients (84% males, age 44 ± 17 years, TBSA% 49 ± 17.5) were included. When cube root of daily insulin dosing was regressed on each time point in a mixed-effects model, statistically significant increase in insulin dosing compared to baseline was observed for -48 (p = 0.018), -24 (p = 0.011), and 0 h (p = 0.008). CONCLUSION Daily insulin dosing increases 48 h prior to development of other clinical signs of sepsis and can be used as a sensitive early marker.

Abstract
Biological markers that evaluate physical healing as well as psychological impact of a burn are essential for effective treatment of paediatric burns. The objective of this review is to summarize the evidence supporting the use of biomarkers in children with burns. An extensive review of the literature was performed using PubMed. A total of 59 biomarkers were identified relating to burn presence, specifically relating to processes involved in inflammation, wound healing, growth and metabolism. In addition, biomarkers involved in the stress response cascade following a burn trauma were also identified. Although many biomarkers have been identified that are potentially associated with burn-related physical and psychological trauma, an understanding of burn biology is still lacking in children. We propose that future research in the field of children’s burns should be conducted using broad screening methods for identifying potential biomarkers, examine the biological interactions of different biomarkers, utilize child-appropriate biological fluids such as urine or saliva, and include a range of different severity burns. Through further research, the biological response to burn injury may be fully realized and clinically relevant diagnostic tests and treatment therapies utilizing these biomarkers could be developed, for the improvement of healing outcomes in paediatric burn patients.

Abstract
Gastrointestinal hormones are essential in postburn metabolism. Since near 50% of burn victims test positive for blood alcohol levels at hospital admission and have inferior outcomes compared to nonintoxicated burn patients; we hypothesized that the gastrointestinal hormone secretion is compromised in intoxicated burn victims. To test our theory, we quantified gastrointestinal hormones serum levels in a combine ethanol intoxication and burn injury mouse model. Thus, mice received a daily dose of ethanol for 3 days, rested 4 days, and were given ethanol 3 additional days. Mice underwent 15% TBSA scald burn 30 minutes after their last ethanol dose. Serum samples were collected 24 hours after burn injury. Nonintoxicated burned mice exhibited an increase in glucose, insulin, ghrelin, plasminogen activator inhibitor-1, leptin, and resistin by 1.4-, 3-, 13.5-, 6.2-, 9.4-, and 2.4-fold, respectively, compared to sham vehicle mice (P < .05). Burn injury also reduced serum gastric inhibitory polypeptide (GIP) by 32% compared to sham-injured, vehicle-treated mice. Leptin, resistin, glucagon-like peptide-1, as well as insulin, were not different from sham groups when intoxication preceded burn injury. Nevertheless, in burned mice treated with ethanol, gastric inhibitory polypeptide and glucagon serum levels exhibited a significant fold increase of 3.5 and 4.7, respectively. With these results, we conclude that 24 hours after burn injury, mice developed significant changes in gastrointestinal hormones, along with hyperglycemia. Moreover, the combined insult of burn and ethanol intoxication led to additional hormonal changes that may be attributed to a potential pancreatic dysfunction. Further multiday studies are required to investigate the etiology, behavior, and clinical significance of these hormonal changes.

The Efficacy of Intensive versus Conventional Insulin Therapy in Reducing Mortality and Morbidity in Medical and Surgical Critically Ill Patients: A Randomized Controlled Study. Anesth Essays Res 2020; 14:295-299.

Abstract
Context Stress hyperglycemia in critically ill patients has been a matter of debate for years without any conclusive answer till date regarding glucose management and treatment thresholds. Aims We planned a study with an aim to compare the efficacy of intensive versus conventional insulin therapy in reducing the mortality and morbidity in critically ill patients. The primary objective was to compare mortality between the two groups. The secondary objective was to find out if intensive insulin therapy is better than conventional insulin therapy in terms of various outcomes such as infections and need for inotropes and transfusion requirements. Settings and Design It was a prospective randomized controlled study. The study population included 100 patients who received mechanical ventilation and admitted to the intensive care department of a tertiary care institute. Subjects and Methods Patients were randomly assigned to two groups: intensive insulin therapy (IIT) and conventional insulin therapy (CIT) to receive either intensive or conventional insulin therapy. Insulin infusion was started only when blood glucose levels exceeded 200 mg%. Blood glucose levels were maintained between 80 and 110 mg% in the IIG and between 180 and 200 mg% in the CIG. Statistical Analysis Used The data collected were analyzed separately for both the groups using Student's t-test and Chi-square test. Results The two groups were comparable in terms of baseline demographic data including age, sex, preadmission diabetic status, and HbA1c at the time of admission. The two groups were not comparable in terms of Acute Physiology and Chronic Health Evaluation-II scores, and the difference between them was statistically significant with higher scores in the conventional group. The primary outcome, that is, mortality, was higher in the CIG with 29 patients (58%) versus 3 (6%) in the IIG (P = 0.02). The secondary outcomes were the measures of morbidity including infections, need for inotropic support, and need for blood transfusions, and these were significantly higher in the conventional group (P < 0.05). Conclusions We conclude that tight glycemic control significantly lowers mortality and morbidity in critically ill patients, both surgical and medical. These benefits appear with the maintenance of tight blood glucose control of 80-110 mg.dL - 1 and not due to administration of insulin.

Sepsis Increases Muscle Proteolysis in Severely Burned Adults, but Does not Impact Whole-Body Lipid or Carbohydrate Kinetics. Shock 2020; 52:353-361.

Abstract
Sepsis is a common and often fatal consequence of severe burn injury, but its exact effects on whole body and muscle metabolism in the burn patient is unclear. To address this, 13 septic and 11 nonseptic patients (age: 36.9 ± 13.0 years) with burns encompassing >30% of their total body surface area underwent muscle protein kinetic studies under postabsorptive conditions using bolus injections of ring-C6 and N phenylalanine isotopes. In parallel, whole-body lipid and carbohydrate kinetics were assessed using constant infusions of [U-C6]palmitate, [6,6-H2]glucose, and [H5]glycerol, and during a 2-h hyperinsulinemic euglycemic clamp. Muscle mRNA levels of genes implicated in the development of muscle cachexia were assessed by qPCR. Fractional breakdown rates of mixed-muscle proteins were found to be 2.4-fold greater in septic versus nonseptic patients (P < 0.05). No discernable differences in fractional synthetic rate of mixed-muscle proteins or rate of appearance of plasma free fatty acids, glycerol, or glucose could be observed between patient groups, although the latter was significantly associated with burn size (P < 0.05). Hyperinsulinemia stimulated whole-body glucose uptake and suppressed endogenous glucose production and whole-body lipolytic rate to equivalent degrees in both groups. Muscle mRNA levels of genes spanning autophagy, lysosomal, and ubiquitin proteasome-mediated proteolysis were not enhanced in septic versus nonseptic patients. Our results demonstrate that accelerated muscle proteolysis appears to be the principal metabolic consequence of sepsis in severe burn patients and could be a contributing factor to the accelerated loss of muscle mass in these individuals. The exact mechanistic basis for these changes remains unclear.

Abstract
In this retrospective cohort study, oral glucose tolerance testing (OGTT) was performed for all enrolled survivors of patients who suffered from acute lymphoblastic leukemia (ALL) at least 9 months after ending chemotherapy, as well as for control group. All demographic, treatment and anthropomorphic data were obtained from medical records. Furthermore, insulin resistance was evaluated according to insulin level, Matsuda and HOMA-IR index. Of 53 subjects, 28 exhibited B-cell ALL, and 25 were healthy children (F/M = 1.12/1). Mean age (±SD) was determined to be 10.77 ± 2.83 years, and meantime off for therapy was also recorded as 3.0 ± 1.6 years. ALL patients were diagnosed at age 1-15 years; none of them received the cranial radiotherapy, and demographic characteristics (age, sex, and sexual maturity) were found to be the same in both groups. Seven patients showed transient hyperglycemia during ALL treatment, however, no significant differences were found in terms of body mass index (BMI) means between ALL patients with and without transient hyperglycemia. Based on the data presented herein, insulin resistance could not be predicted by glucose levels during therapy, cumulative asparaginase, and steroid. Our findings demonstrated that elevated BMI could be a valuable predictor of insulin resistance probability in ALL patients. The presence of transient hyperglycemia does not appear to be associated with the increased risk of glucose intolerance or insulin resistance in the first few years after completion of therapy.

Abstract
OBJECTIVE To review the effects of burn injury on nutritional requirements and how this can best be supported in a healthcare setting. METHOD A literature search for articles discussing nutrition and/or metabolism following burn injury was carried out. PubMed, Embase and Web of Science databases were searched using the key search terms 'nutrition' OR 'metabolism' AND 'burn injury' OR 'burns'. There was no limitation on the year of publication. RESULTS A total of nine articles met the inclusion criteria, the contents of which are discussed in this manuscript. CONCLUSION Thermal injury elicits the greatest metabolic response, among all traumatic events, in critically ill patients. In order to ensure burn patients can meet the demands of their increased metabolic rate and energy expenditure, adequate nutritional support is essential. Burn injury results in a unique pathophysiology, involving alterations in endocrine, inflammatory, metabolic and immune pathways and nutritional support needed during the inpatient stay varies depending on burn severity and idiosyncratic patient physiologic parameters.

Front Vet Sci 2020; 6:480. [PMID: 31998762 PMCID: PMC6961514 DOI: 10.3389/fvets.2019.00480] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2019] [Accepted: 12/06/2019] [Indexed: 12/17/2022] Open
Abstract
In several species, intermittent fasting (IF) has been shown to have beneficial effects, including delayed aging, increased lifespan, increased insulin sensitivity, reduced ischemic tissue damage, delayed onset of neurodegenerative disease and improved neuronal repair following injury. However, the metabolic and immunological effects of IF have not been well-established in dogs. The aim of this study was to examine the effects of a 48 h IF regimen using a low fat and a high fat diet in healthy dogs by quantifying the metabolic, hormonal, and immunological changes. We hypothesized that IF dogs would have higher blood ketone and ghrelin concentrations, lower blood leptin, insulin and glucose concentrations, and signs of immunosuppression compared to dogs eating daily. Ten healthy adult dogs were randomized into three group and underwent three feeding regimes in a 3 × 3 Latin square design: twice a day feeding on a low fat (23% energy from fat; LF) diet, 48 h fasting on a low fat diet, and 48 h fasting on a high fat enriched with medium-chain triglycerides (68% energy from fat; HF) diet. Body weight, food intake, activity, blood glucose, β-hydroxybutyrate, leptin, ghrelin, and insulin were measured. Lymphocyte proliferation and neutrophil/macrophage phagocytosis and respiratory burst were measured as markers of immune function. Nuclear magnetic resonance spectroscopy was used to relatively quantify plasma metabolites. When the dogs were IF on a HF diet, they had the highest concentration of blood ketones (mean 0.061 mmol/L, SD 0.024), whereas they had the lowest concentration (mean 0.018 mmol/L, SD 0.004) when fed daily. Blood glucose and insulin concentrations were lower in IF dogs on a HF diet compared to daily feeding or IF on a LF diet. There was an increase in plasma β-hydroxybutyrate concentrations, and a reduction in glucose and insulin concentrations when dogs were IF on a HF diet. There was only a decline in the immune parameters studied when the dogs were IF on a LF diet, which was not seen when on the HF diet. The results of this study indicate the potential of IF to be further investigated as a potential beneficial feeding regime for dogs.

Abstract
Background Diabetes is the most common comorbidity of necrotizing fasciitis (NF), but the effect of stress-induced hyperglycemia (SIH) on diabetic patients with NF has never been investigated. The aim of this study was to assess whether SIH, as determined by the glycemic gap between admission glucose levels and A1C-derived average glucose levels, predicts adverse outcomes in diabetic patients hospitalized with NF. Methods We retrospectively reviewed the glycemic gap and clinical outcomes in 252 diabetic patients hospitalized due to NF from 2011 to 2018 in a single medical center in Taiwan. A receiver operating characteristic (ROC) curve was used to analyze the optimal cutoff values for predicting adverse outcomes. Univariate and multivariate logistic regression analyses were employed to identify significant predictors of adverse outcomes. Results In total, 194 diabetic NF patients were enrolled. Compared with patients without adverse outcomes, patients with adverse outcomes had significantly higher glycemic gaps, Acute Physiology and Chronic Health Evaluation (APACHE) II scores and C-reactive protein (CRP) levels; lower albumin and hemoglobin levels; greater incidence of limb loss; and longer hospital and intensive care unit stays. The glycemic gap positively correlates with the laboratory risk indicator for NF scores, APACHE II scores and CRP levels. A glycemic gap of 146 mg/dL was the optimal cutoff value for predicting adverse outcomes using the ROC curve. Compared with patients with glycemic gaps ≤146 mg/dL, those with glycemic gaps >146 mg/dL had higher APACHE II scores and incidence rates of adverse outcomes, especially bacteremia and acute kidney injury. Multivariate analysis revealed that a glycemic gap >146 mg/dL and APACHE II score >15 were independent predictors of adverse outcomes, while the presence of hyperglycemia at admission was not. Conclusions An elevated glycemic gap was significantly independently associated with adverse outcomes in diabetic NF patients. Further prospective studies are warranted to validate the role of the glycemic gap in NF patients with diabetes.

Abstract
Cutaneous wound healing is a complex orchestrated process influenced by many endogenous and exogenous imbalances. The main goal of tissue regeneration in wound healing is to increase wound contraction and reduce scar formation, effectively to regenerate a new healthy epidermis and prevent scar contracture. Additionally, prevention, control and treatment of wound infections, particularly in burn wounds, is a vital strategy in the healing process. It was previously supposed that local application of sugar-based materials increases the chance of wound infection and delays wound healing. This review shows that topical application of sugar-based compounds has no negative effects on different wound types. Whereas, hyperglycaemia created by diabetes, stress or certain medications can act to impair wound healing. Therefore, this work was designed to review the recent studies that evaluated the role of sugar-based compounds on wound healing and to demonstrate in various cutaneous wound models how these compounds may be involved in healing. It also deals with different physio-pharmacologic conditions resulting in hyperglycaemia in different models of cutaneous wound healing in order to illustrate the role of endogenous glucose in wound healing and remodelling.

Abstract
Background The effects of diabetes mellitus (DM) on mortality and morbidities in burn patients have not been sufficiently elucidated. Objective The present study aimed to investigate the effects of DM on the mortality, length of hospital stay, and number of operations in burn patients. Methods A retrospective cohort study was performed using medical records of 3,220 burn patients. Multiple logistic regression, linear regression, and Poisson regression models were used to determine whether DM increases mortality in patients with burn injury, whether DM prolongs length of hospital stay in burn survivors, and whether DM increases the number of operations in burn survivors, respectively. Results After adjusting for potential confounding factors, DM significantly increased odds of death in burn patients (adjusted odds ratio 3.225 [95% confidence interval 1.405~7.400], p=0.006). DM also increased the mean length of hospital stay in burn survivors (adjusted mean ratio 1.312 [95% confidence interval 1.198~1.437], p<0.001). Furthermore, DM significantly increased the mean number of operations in burn survivors (adjusted mean ratio 1.576 [95% confidence interval 1.391~1.785], p<0.001). Conclusion DM increases mortality, elongates hospital stay and makes more operations required in patients with burn injury.

Abstract
OBJECTIVE This study aimed to study the incidence of stress hyperglycemia in critically ill children and to investigate the etiological basis of the hyperglycemia based on homeostasis model assessment. METHODS This was a prospective cohort study in one of the pediatric intensive care units of Cairo University, including 60 critically ill children and 21 healthy controls. Serum blood glucose, insulin, and C-peptide levels were measured within 24 hours of admission. Homeostasis model assessment was used to assess β-cell function and insulin sensitivity. RESULTS Hyperglycemia was estimated in 70% of patients. Blood glucose values ≥ 180mg/dL were associated with a poor outcome. Blood glucose levels were positively correlated with Pediatric Risk for Mortality (PRISM III) score and number of organ dysfunctions (p = 0.019 and p = 0.022, respectively), while insulin levels were negatively correlated with number of organ dysfunctions (r = -0.33, p = 0.01). Homeostasis model assessment revealed that 26 (43.3%) of the critically ill patients had low β-cell function, and 18 (30%) had low insulin sensitivity. Combined pathology was detected in 2 (3.3%) patients only. Low β-cell function was significantly associated with the presence of multi-organ dysfunction; respiratory, cardiovascular, and hematological dysfunctions; and the presence of sepsis. CONCLUSIONS β-Cell dysfunction appeared to be prevalent in our cohort and was associated with multi-organ dysfunction.

Abstract
PURPOSE OF REVIEW Non-diabetic hyperglycemia (NDHY) is a pathological condition that is not yet well known. The aim of this review is to examine approaches for management of this condition. RECENT FINDINGS While it is well known that persistent hyperglycemia in diabetes affects immune response and risk for diabetes-related micro- and macrovascular complications, little is known about the biological effects of transient NDHY, particularly in the pediatric age group. Stress HY (SHY) is typically defined as blood glucose > 8.33 mmol/L (150 mg/dL) during physical stress, resolving spontaneously after dissipation of acute illness in patients without known diabetes. Based on the literature and clinical practice, two situations can be classified: (1) SHY1, which occurs during severe and prolonged illness and under serious life-threatening conditions, mainly in emergency situations and in resuscitation areas; and (2) SHY2, which occurs during acute illness, mainly in non-life-threatening conditions. Furthermore, (NDHY) among pediatric patients can be induced by drugs; the most frequent conditions are secondary to (1) steroid therapy and (2) antineoplastic/immunosuppressive therapy.

Abstract
BACKGROUND Parenteral Nutrition (PN) is prescribed to children with intestinal failure. Although life saving, complications are common. Recommendations for indications and constituents of PN are made in the 2005 guidelines by the European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN). The aim of this study was to establish if the indications for prescribing PN in a tertiary children's hospital were appropriate, and to identify complications encountered. Data were compared to those published by the National Confidential Enquiry into patient outcome and death (NCEPOD) carried out in the United Kingdom in 2010. METHODS Children and newborns receiving inpatient PN over a 6 months period were entered into the study and data was collected prospectively. The appropriate indications for the use of PN were based on the ESPGHAN guidelines. Recorded complications were divided into metabolic, central venous catheter (CVC) related, hepatobiliary and nutritional. RESULTS A total of 303 children (67 newborns) were entered into the study. The main indications for the start of PN were critical illness (66/303), surgery (63/303) and bone marrow transplantation (28/303). The ESPGHAN recommendations were followed in 91.7% (278/303) of cases (95.5% of newborns, 90.7% of children). PN was considered inappropriate in 12/303 patients and equivocal in 13. The mean PN duration was 18 days (1-160) and the incidence of complications correlated to the length of PN prescribed. Metabolic, hepatobiliary and CVC related complications affected 74.6, 24.4, 16.4% of newborns and 76.7, 37.7 and 24.6% of children respectively. In relation to the appropriate indications for the start of PN our results mirrored those reported by the NCEPOD audit (92.4% of newborns and 88.6% children). However, the incidence of metabolic disturbances was higher in our cohort (74.6% vs 30.4% in children, 76.7% vs 14.3% in newborns) but CVC related complications lower amongst our newborns (16,4% vs 25%). CONCLUSIONS Although the indications for inpatient PN in children is mostly justified, there is still a proportion who is receiving PN unnecessarily. PN related complications remain common. There is a need for better education amongst health professionals prescribing PN and access to nutritional support teams to reduce unwanted side effects.

Abstract
Background: Glycemic control in burn patients is critical for reducing infection and mortality. Objective: This study was conducted to assess the incidence and outcomes of hypoglycemia during continuous insulin infusions (CII). Methods: This institutional review board-approved study was a retrospective, single burn center, electronic chart review. Patients admitted between January 1, 2013, and October 31, 2014, who received a CII were included. Patients with incomplete data or who received <24 hours of CII were excluded. Results: Thirty-eight patients met inclusion criteria; 6 were excluded. The average patient was a 52-year-old Caucasian male with a 33% total body surface area burn and an acute physiology and chronic health evaluation (APACHE) II score of 20.Hypoglycemia was present for 87 of 6540 hours of CII therapy (1.1%). Two-thirds experienced a serum glucose <70 mg/dL and half <60 mg/dL. The most commonly assessed reasons for the hypoglycemic episodes were protocol violations (47%) and glucose variability (30%). After multivariable logistic regression, only history of diabetes remained a statistically significant risk factor with an odds ratio of 15.4 (95% confidence interval: 2.5-95.1). Four different CII protocols were prescribed. All protocols had a high glucose variability, as assessed by hours / day within goal range (13.1 ± 2.5, 14.1 ± 3.1, 14.3 ± 2.4, 9.8; P = .282). Conclusion: The amount of different protocols likely contributed to protocol violations and glucose variability. Our data demonstrate the need to create and consolidate usage to a single protocol in attempts to improve glycemic control.

Abstract
BACKGROUND The standard of burn treatment today reflects major advances. We sought to quantitate the impact of these advances on burn survival via age-stratified mortality ratios compared with other reported mortality analyses in burns. STUDY DESIGN Age, percent of the total body surface area (TBSA) burned, presence of inhalation injury, length of stay, and survival status were recorded at admission and at discharge for all new burn admissions between 1989 and 2017. The expected mortality probability was calculated using historical multiple regression techniques and compared with observed data. We developed a prediction model for our observed data. RESULTS Between 1989 and 2017, there were 10,384 consecutive new burn admissions, with 355 mortalities (median age, 13 years; median percent TBSA burn, 11%). We saw a significant decrease in our observed mortality data compared to historical predictions (p < 0.0001), and a 2% reduction per year in mortality during the 3 decades. The prediction model of mortality for the data is as follows: Pr(dying) = ex/(1 + ex) where x = -6.44 - 0.12 age + 0.0042 age2 - 0.0000283 age3 + 0.0499 TBSA + 1.21 Inhalation Injury + 0.015 third degree TBSA. CONCLUSIONS The reduction in mortality over time may be attributed to successful changes in standard of care protocols in the burn center that improved the outlook for burned individuals, including protocols for management of inhalation injury, nutrition, resuscitation, and early excision and grafting.

Abstract
The widespread and rapidly increasing trend of binge drinking is accompanied by a concomitant rise in the prevalence of trauma patients under the influence of alcohol at the time of their injury. Epidemiological evidence suggests up to half of all adult burn patients are intoxicated at the time of admission, and the presence of alcohol is an independent risk factor for death in the early stages post burn. As the major site of alcohol metabolism and toxicity, the liver is a critical determinant of postburn outcome, and experimental evidence implies an injury threshold exists beyond which burn-induced hepatic derangement is observed. Alcohol may lower this threshold for postburn hepatic damage through a variety of mechanisms including modulation of extrahepatic events, alteration of the gut-liver axis, and changes in signaling pathways. The direct and indirect effects of alcohol may prime the liver for the second-hit of many overlapping physiologic responses to burn injury. In an effort to gain a deeper understanding of how alcohol potentiates postburn hepatic damage, the authors summarize possible mechanisms by which alcohol modulates the postburn hepatic response.

Abstract
Numerous studies have examined the strategy of tight glucose control (TGC) with intensive insulin therapy (IIT) to improve clinical outcomes in critically ill adults and children. Although early studies of TGC with IIT demonstrated improved outcomes at the cost of elevated hypoglycemia rates, subsequent studies in both adults and children have not demonstrated any benefit from such a strategy. Differences in patient populations, variable glycemic targets, and glucose control protocols, inconsistency in attaining these targets, heterogeneous intermittent sampling, and measurement techniques, and variable expertise in protocol implementation are possible reasons for the contrasting results from these studies. Notably, differences in modes of nutrition support may have also contributed to these disparate results. In particular, combined use of early parenteral nutrition (PN) and a strategy of TGC with IIT may be associated with improved outcomes, while combined use of enteral nutrition (EN) and a strategy of TGC with IIT may be associated with equivocal or worse outcomes. This article critically examines published clinical trials that have employed a strategy of TGC with IIT in critically ill children to highlight the role of EN vs. PN in influencing clinical outcomes including efficacy of TGC, and adverse effects such as occurrence of hypoglycemia and hospital acquired infections. The perspective afforded by this article should help practitioners consider the potential importance of mode of nutrition support in impacting key clinical outcomes if they should choose to employ a strategy of TGC with IIT in critically ill children with hyperglycemia.

Abstract
BACKGROUND Diabetes mellitus (DM) is a major cause of illness and death in the United States, and diabetic patients are at increased risk for burn injury. We therefore sought to examine the impact of pre-existing DM on the risk of inpatient mortality and hospital acquired infections (HAI) among burn patients. METHODS Adult patients (≥18 years old) admitted from 2004 to 2013 were analyzed. Weighted Kaplan-Meier survival curves - adjusting for patient demographics, burn mechanism, presence of inhalation injury, total body surface area, additional comorbidities, and differential lengths of stay - were used to estimate the 30-day and 60-day risk of mortality and HAIs. RESULTS A total of 5539 adult patients were admitted and included in this study during the study period. 655 (11.8%) had a pre-existing DM. The crude incidence of HAIs and in-hospital mortality for the whole burn cohort was 8.5% (n=378) and 4.4% (n=243), respectively. Diabetic patients were more likely to be older, female, have additional comorbidities, inhalational injury, and contact burns. After adjusting for patient and burn characteristics, the 60-day risk of HAI among patients with DM was significantly higher, compared to non-diabetic patients (RR 2.07, 95% CI 1.28, 6.79). However, no significant difference was seen in the 60-day risk of mortality (RR 1.34, 95% CI 0.44, 3.10). CONCLUSIONS Pre-existing DM significantly increases the risk of developing an HAI in patients following burn injury, but does not significantly impact the risk of inpatient mortality. Further understanding of the immune modulatory mechanism of burn injury and DM is imperative to better attenuate the acquisition of HAIs.

Abstract
A severe burn can trigger a hypermetabolic state which lasts for years following the injury, to the detriment of the patient. The drastic increase in metabolic demands during this phase renders it difficult to meet the body's nutritional requirements, thus increasing muscle, bone and adipose catabolism and predisposing the patient to a host of disorders such as multi-organ dysfunction and sepsis, or even death. Despite advances in burn care over the last 50 years, due to the multifactorial nature of the hypermetabolic phenomenon it is difficult if not impossible to precisely identify and pharmacologically modulate the biological mediators contributing to this substantial metabolic derangement. Here, we discuss biomarkers and molecules which play a role in the induction and mediation of the hypercatabolic condition post-thermal injury. Furthermore, this thorough review covers the development of the factors released after burns, how they induce cellular and metabolic dysfunction, and how these factors can be targeted for therapeutic interventions to restore a more physiological metabolic phenotype after severe thermal injuries. This article is part of a Special Issue entitled: Immune and Metabolic Alterations in Trauma and Sepsis edited by Dr. Raghavan Raju.

Differential expression of microRNA let-7b-5p regulates burn-induced hyperglycemia. Oncotarget 2017; 8:72886-72892. [PMID: 29069833 PMCID: PMC5641176 DOI: 10.18632/oncotarget.20543] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2017] [Accepted: 07/31/2017] [Indexed: 01/09/2023] Open
Abstract
One of the classical features observed in patients with burn injury is hyperglycemia. There have been previous reports that a cohort of microRNAs (miRNAs) is differentially expressed in the dermis of patients with burn injury. More specifically, it has been shown that the miR-194 can target the insulin-like growth factor receptor 1 (IGF1R) and silence its protein expression resulting in hyperglycemia. The objective of the current study was to discover if additional miRNA-mediated post-transcriptional mechanism exists that lead to suppression of IGF1R protein expression post-burn injury. Using the 30% total body surface area (TBSA) model of burn injury in rats we found that the miRNA let-7b can target IGF1R and downregulate its protein expression, in turn attenuating PI3K/Akt and Gsk3β activation leading to hyperglycemia. Increased let-7b expression was significantly more than the previously reported miR-194 both in the burn rats compared to sham and in patients with burn injury compared to healthy subjects. Serum from burn rats also resulted in decreased IGF1R protein expression in rat L6 myotubes. In vivo targeting of let-7b by antagomir mitigated the effect of increased let-7b expression on IGF1R protein expression and hyperglycemia. Thus targeting let-7b might be a promising approach to treat hyperglycemia in patients with burn injury.

Abstract
OBJECTIVE To determine whether metformin can achieve glucose control no worse than insulin (noninferiority) without the danger of hypoglycemia (superiority). In addition, to assess whether metformin has any additional effects on lipolysis and inflammation that will enhance burn recovery (superiority). SUMMARY BACKGROUND DATA Hyperglycemia and insulin resistance after burn injury are associated with increased morbidity and mortality. Insulin administration improves postburn infections, severity of sepsis, and morbidity, but also causes a 4-5-fold increase in hypoglycemia, which is associated with a 9-fold increase in mortality. METHODS Severely burned adult patients with burns over 20% total body surface area (TBSA) burn were prospectively randomized in this Phase II clinical trial to either metformin or insulin (standard of care) treatment. Primary outcomes were glucose levels and incidence of hypoglycemia. Secondary outcomes included glucose and fat metabolism, and clinical outcomes. RESULTS Forty-four patients were enrolled in this Phase II clinical trial, 18 metformin and 26 insulin patients. Demographics, burn size, concomitant injuries, and mortality were comparable between both groups. Metformin controlled blood glucose as equally as insulin with no difference between the 2 treatment groups, P > 0.05. While there was a 15% incidence of hypoglycemia in the insulin group, there was only 1 mild hypoglycemic episode (6%) in the metformin group, P < 0.05. Oral glucose tolerance tests at discharge revealed that metformin significantly improved insulin sensitivity, P < 0.05. Furthermore, metformin had a strong antilipolytic effect after burn injury when compared with insulin and was associated with significantly reduced inflammation, P < 0.05. CONCLUSIONS Metformin decreases glucose equally as effective as insulin without causing hypoglycemia, with additional benefits including improved insulin resistance and decreased endogenous insulin synthesis when compared with insulin controls. These results indicate that metformin is safe in burn patients and further supports the use of metformin in severely burned patients for postburn control of hyperglycemia and insulin resistance.

Abstract
BACKGROUND The purpose of this study was to determine if protocol-driven normoglycemic management in trauma patients affected glucose control, ventilator-associated pneumonia, surgical-site infection, and inpatient mortality. METHODS A prospective, consecutive-series, historically controlled study design evaluated protocol-driven normoglycemic management among trauma patients at Vanderbilt University Medical Center. Those mechanically ventilated > or =24 hours and > or =15 years of age were included. A glycemic-control protocol required insulin infusion therapy for glucose >110 mg/dL. Control patients included those who met criteria, were admitted the year preceding protocol implementation, and had hyperglycemia treated at the physician's discretion. RESULTS Eight hundred eighteen patients met study criteria; 383 were managed without protocol; 435 underwent protocol. The protocol group had lower glucose levels 7 of 14 days measured. After admission, both groups had mean daily glucose levels <150 mg/dL. No difference in pneumonia (31.6% vs 34.5%; p = .413), surgical infection (5.0% vs 5.7%; p = .645) or mortality (12.3% vs 13.1%; p = .722) occurred between groups. If one episode of blood glucose level was > or =150 mg/dL (n = 638; 78.0%), outcomes were worse: higher daily glucose levels for 14 days after admission (p < .001), pneumonia rates (35.9% vs 23.3%; p = .002), and mortality (14.6% vs 6.1%; p = .002). One or more days of glucose > or =150 mg/dL had a 2- to 3-fold increase in the odds of death. Protocol use in these patients was not associated with outcome improvement. CONCLUSIONS Protocol-driven management decreased glucose levels 7 of 14 days after admission without outcome change. One or more glucose levels > or =150 mg/dL were associated with worse outcome.

Abstract
Hypermetabolism is the ubiquitous response to a severe burn injury, which was first described in the nineteenth century. Despite identification of important components of this complex response, hypermetabolism is still not well understood in its entirety. This article describes this incredibly fascinating response and the understanding we have gained over the past 100 years. Additionally, this article describes novel insights and delineates treatment options to modulate postburn hypermetabolism with the goal to improve outcomes of burn patients.

Abstract
OBJECTIVES Management of hyperglycemia during an acute sickness in adults is accompanied by improved outcomes. We have designed a prospective study with meticulous attention to exclude all diabetes patients by checking hemoglobin A1c (HbA1c or glycated hemoglobin) to avoid the ill-effects of hyperglycemia in patients with traumatic head injury admitted to the intensive care unit (ICU). METHODS This prospective study included adults with traumatic primary brain injury with a Glasgow coma score of ≤8 necessitating mechanical ventilation treated in the period 2012-2015. After screening 311 patients, 220 were included in the study. Both blood glucose and HbA1c levels of all the patients at admission, as well as blood glucose level after 72 hours, were obtained from the records. The patients were later grouped based on their admission blood glucose levels (<200 mg/dL or ≥200 mg/dL). Injury severity score (ISS) was documented for every patient. As a final point, the outcomes were determined based on the hospital length of stay (HLS) and ICU length of stay (ILS), plusmortality rates. RESULTS About 39% (n = 85) of patients were admitted with hyperglycemia during the study period. The mortality rate in patients with glucose ≥200 mg/dL was 65.8% (N = 56), against 23.7% (N = 32) in the group with glucose <200 mg/dL, with mortality rising as the blood glucose level increased (P = 0.014). CONCLUSIONS We conclude that admission hyperglycemia is related with increased mortality rate in head injury patients, and comprehensive treatment of hyperglycemia can improve the outcome of severe head injury patients.

Abstract
INTRODUCTION Burn Wound Infection (BWI) is primarily caused by aerobic bacteria followed by fungi, anaerobes and viruses. There has been a worldwide decrease in incidence of bacterial infections in burns due to better patient care and availability of effective antibiotics. Consequently, the fungal burn wound infection has shown an increasing trend. AIM The aim of study was to assess the frequency of fungal infections in thermal burn wounds with respect to age of wounds, total body surface involved, depth of burns and to assess common fungal pathogens. MATERIALS AND METHODS The study was conducted on 50 patients admitted with thermal burn wounds having 20-60% burns in the surgical unit. Pus swab and scrapings were taken under local anaesthesia from each burn patient. Scrapings were put in a sterile container and sent to Mycology section of Microbiology department and were examined by direct microscopy and culture studies on Sabouraud's Dextrose Agar medium in the Mycology section of Microbiology department. RESULTS In our study, the incidence of fungal infection in burn wound patients came out to be 26%. The incidence of fungal infection increased with increase in Total Body Surface Area, (TBSA) increase in depth and age of burn. In our study, the maximum positive fungal cultures were seen in the third week of post-burn period. No positive culture was seen in the first week and 30.76% positive fugal cultures were seen in second post-burn week. Candida albicans was found to be the most common organism followed by Non-albicans Candida and Aspergillus. CONCLUSION It was concluded from the study that incidence of fungal infections in thermal burns increased with increase in post-burn period and with increasing depth and TBSA of burns. Candida albicans was found to be the most common fungus.

Abstract
OBJECTIVES The study aimed to determine the prevalence of hyperglycemia in sick children admitted into the emergency rooms and to investigate its relationship with adverse outcomes. METHODS A prospective study involving 2 tertiary hospitals in Lagos. Study subjects included all children aged beyond 1 month. An Accu-Chek Active glucometer was used for the bedside blood glucose determination. Hyperglycemia was defined as blood glucose greater than 7.8 mmol/L. RESULTS A total of 1045 patients were recruited with hyperglycemia being recorded in 135 patients (prevalence rate of 12.9%). Mean age of the hyperglycemic patients was 29.0 ± 31.23 months. Prevalence rates of hyperglycemia among the leading diagnoses were 17.4% in acute respiratory tract infections, 11% in malaria, 15.3% in septicemia, 14.9% in gastroenteritis, and 18.2% in burns. Other conditions include sickle cell anemia, meningitis, and malnutrition. Mortality rate was significantly higher overall in hyperglycemic compared with the normoglycemic patients (15.4% vs 8.0%, P = 0.011). With regard to specific diagnoses, significantly higher mortality rates were recorded in hyperglycemic patients with acute respiratory tract infections (28% vs 8%, P = 0.011) and malaria (21.4% vs 5.0%, P = 0.006) than in their normoglycemic counterparts. CONCLUSIONS Hyperglycemia is common in ill children admitted to the emergency rooms and is associated with 2 to 4 times higher mortality in common childhood diseases encountered. Blood glucose determination is important in all acutely ill children at presentation. The practice of empirical administration of intravenous glucose in some resource-constrained facilities where blood glucose testing facilities are not readily available should be discouraged.

Abstract
OBJECTIVES Metabolic alterations after burn injury have been well described in children; however, in adult patients, glucose metabolism and insulin sensitivity are essentially unknown. We sought to characterize metabolic alterations and insulin resistance after burn injury and determine their magnitude and persistence at discharge. DESIGN Prospective, cohort study. SETTING Tertiary burn centre. PATIENTS Nondiabetic adults with an acute burn involving greater than or equal to 20% total body surface area. INTERVENTIONS An oral glucose tolerance test was administered at discharge. MEASUREMENTS AND MAIN RESULTS Glucose, insulin, and C-peptide levels were measured to derive surrogate measures of insulin resistance and β-cell function, including quantitative insulin sensitivity check index, homeostasis model assessment of β-cell function, homeostasis model assessment of insulin sensitivity, homeostasis model assessment of insulin resistance, and the composite whole-body insulin sensitivity index. Patients were grouped according to the degree of glucose tolerance: normal glucose tolerance, impaired fasting glucose/impaired glucose tolerance, or diabetes. Forty-five adults, 44 ± 15 years old and with 38% ± 14% total body surface area burned, underwent an oral glucose tolerance test at discharge. Median quantitative insulin sensitivity check index (0.348 [0.332-0.375]) and median homeostasis model assessment of insulin resistance (1.13 [0.69-1.45]) were abnormal, indicating insulin resistance and impaired insulin production at discharge. Two-thirds of patients (n = 28) met criteria for impaired fasting glucose/impaired glucose tolerance or diabetes. CONCLUSIONS We have demonstrated that burn-injured adults remain hyperglycemic, are insulin resistant, and express defects in insulin secretion at discharge. Patients with lower burn severity (total body surface area, 20-30%) express similar metabolic alterations as patients with larger burns (total body surface area, ≥ 30%). Glucose tolerance testing at discharge offers an opportunity for early identification of burn patients who may be at high risk of prediabetes and diabetes. Our findings demonstrated that two-thirds of burn patients had some degree of glucose intolerance. With this in mind, surveillance of glucose intolerance post discharge should be considered. As hyperglycemia and insulin resistance are associated with poor outcomes, studies should focus on how long these profound alterations persist.

Abstract
Burn wound sepsis is currently the main cause of morbidity and mortality after burn trauma. Infections by notorious pathogens such as Pseudomonas aeruginosa, Staphylococcus aureus, and Acinetobacter baumannii impair patient recovery and can even lead to fatality. In this study, we investigated the effect of burn wound exudates (BWEs) on the virulence of those pathogens. BWEs were collected within 7 days after burn trauma from 5 burn patients. We first monitored their effect on pathogen growth. In contrast to A. baumannii and S. aureus, P. aeruginosa was the only pathogen able to grow within these human fluids. Expression of typical virulence factors such as pyocyanin and pyoverdine was even enhanced compared the levels seen with standard laboratory medium. A detailed chemical composition analysis of BWE was performed, which enabled us to determine the major components of BWE and underline the metabolic modifications induced by burn trauma. These data are essential for the development of an artificial medium mimicking the burn wound environment and the establishment of an in vitro system to analyze the initial steps of burn wound infections. IMPORTANCE Microbial infection of severe burn wounds is currently a major medical challenge. Of the infections by bacteria able to colonize such injuries, those by Pseudomonas aeruginosa are among the most severe, causing major delays in burn patient recovery or leading to fatal issues. In this study, we investigated the growth properties of several burn wound pathogens in biological fluids secreted from human burn wounds. We found that P. aeruginosa strains were able to proliferate but not those of the other pathogens tested. In addition, burn wound exudates (BWEs) stimulate the expression of virulence factors in P. aeruginosa. The chemical composition analysis of BWEs enabled us to determine the major components of these fluids. These data are essential for the development of an artificial medium mimicking the burn wound environment and for in vitro analysis of the initial step in the development of burn wound infections.

Abstract
Background: Hyperglycemia is frequently encountered in critically ill patients and has been shown to contribute to both morbidity and mortality. We aimed to study the predictive role of blood glucose level in clinical outcomes of mechanically ventilated patients with traumatic brain injury during intensive care unit (ICU) stay and to explore its relationship with Glasgow coma scale (GCS) and acute physiology and chronic health examination (APACHE) II scores that are used in the evaluation of ICU patients as predictor. Materials and Methods: A total of 185 patients with craniocerebral trauma who were hospitalized in the ICU were included in the study. Comparisons of mean glucose values (MGVs) and APACHE II scores between survivors and nonsurvivors were made with Student's t-test and chi-square test. Survival analysis was performed with log rank (Mantel-Cox) test and Cox regression was used for mortality risk factors analysis. Results: MGVs at the initial, last, and all measurements were significantly higher for nonsurvivors than for survivors. Hazard rate at any given time point for patients with mean glucose value (MGV) between 150 and 179 was found to be 3.691 times that of patients with MGV values between 110 and 149. The hazard rate at any given time point for patients with MGV values ≥180 was found to be 6.571 times that of patients with MGV values between 110 and 149. Conclusion: High glucose level is an independent risk factor for mortality in mechanically ventilated ICU patients with traumatic brain injury.

Abstract
BACKGROUND Self-monitoring of blood glucose (SMBG) is an important component of management for diabetes mellitus (DM), especially in T1DM and T2DM patients who are on insulin therapy. Adequate blood glucose monitoring and prompt intervention are necessary to prevent blood glucose (BG) fluctuation and delay long-term diabetes complications. People with DM are advised to clean their hands before SMBG to remove any dirt or food residue that might affect the reading. AIM The study tested the hypothesis that falsely elevated BG levels from fingertip occur after peeling or handling fruits in an unwashed hand. METHODS Fifty apparently healthy nondiabetes volunteers were enrolled. Capillary BG samples were collected from the fingertips after peeling or handling apple, orange, banana, watermelon, and pawpaw, followed by no hand washing for 1 h, cleaning the fingertip with alcohol swab once, five times, and washing hand thoroughly with tap water and drying. These samples were then analyzed with two different glucose meters. RESULTS The mean BG values, measured from fingertip blood samples after peeling, and handling any of the fruits followed by no hand washing were significantly high, even after cleaning fingertip with a swab of alcohol once. However, there were no significant difference in BG levels measured after peeling and handling fruits followed by hand washing and the level of BG before peeling and handling fruits. CONCLUSION Handling of peeled fruits with no hand washing with tap water is associated with overestimation of capillary BG (Pseudohyperglycemia) monitored with glucose meters.

Abstract
BACKGROUND Inpatients with diabetes have longer length of stays (LOS). Understanding patterns of in-hospital complications between patients with diabetes and others may reveal measures to improve patient welfare and minimise LOS. AIM This study evaluates the rates and types of hospital-acquired conditions among patients with and without diabetes and assesses any effects on LOS. METHODS A total of 47 615 admission episodes from The Northern Hospital over 12 months was reviewed. Episodes were divided into four groups: (i) patients without diabetes; (ii) patients with diabetes without end-organ sequelae (EOS); (iii) patients with diabetes with EOS; and (iv) a subset of non-diabetic patients with a Charlson Co-morbidity score ≥1 (comparison group). The Classification of Hospital Acquired Diagnoses (CHADx) was applied to the groups to compare rates and types of inpatient complications. Linear regression was used to analyse the impact of the number of CHADx on LOS. RESULTS Almost 30% of admissions of patients with diabetes and EOS had at least one CHADx, compared with 13% for non-diabetes patients and 17% for the comparison group. The types of CHADx experienced by diabetes patients with EOS were similar to the comparison group. However, rates were 10 times higher. Linear regression demonstrated diabetes patients with EOS have increased LOS and each CHADx per episode has a larger effect on LOS. CONCLUSION We demonstrate that diabetes patients have consistently higher rates of CHADx and longer LOS than similar patients with complex and chronic conditions. This provides a foundation for future studies to investigate preventative practices for this high-risk patient population.

Abstract
Stress-induced hyperglycemia is common in critically ill patients, where elevated blood glucose and glycemic variability have been found to contribute to infection, slow wound healing, and short-term mortality. Early clinical studies demonstrated improvement in mortality and morbidity resulting from intensive insulin therapy targeting euglycemia. Follow-up clinical studies have shown mixed results suggesting that the risk of hypoglycemia may outweigh the benefits of aggressive glycemic control. None of the prior studies clarify whether euglycemic targets are in themselves harmful, or if the danger lies in the inadequacy of the available methods for achieving desired glycemic outcomes. In this paper, we use a recently developed simulation model of stress hyperglycemia to demonstrate that given an insulin protocol glycemic outcomes are specific to the patient population under consideration, and that there is a need to optimize insulin therapy at the population level. Next, we use the simulator to demonstrate that the performance of Adaptive Proportional Feedback (APF), a popular format for computerized insulin therapy, is sensitive to its parameters, especially to the parameters that govern the aggressiveness of adaptation. Finally, we propose a framework for simulation-based protocol optimization using an objective function that penalizes below-range deviations more heavily than comparable deviations above.

Abstract
Nutritional support for critically ill infants and children is of paramount importance and can greatly affect the outcome of these patients. The energy requirement of children is unique to their size, gestational age, and physiologic stress, and the treatment algorithms developed in adult intensive care units cannot easily be applied to pediatric patients. This article reviews some of the ongoing controversial topics of fluid, electrolyte, and nutritional support for critically ill pediatric patients focusing on glycemic control and dysnatremia. The use of enteral and parenteral nutrition as well as parenteral nutritional-associated cholestasis will also be discussed.

Abstract
BACKGROUND ICU-acquired weakness (ICU-AW) has immediate and long-term consequences for critically ill patients. Strategies for the prevention of weakness include modification of known risk factors, such as hyperglycemia and immobility. Intensive insulin therapy (IIT) has been proposed to prevent critical illness polyneuropathy. However, the effect of insulin and early mobilization on clinically apparent weakness is not well known. METHODS This is a secondary analysis of all patients with mechanical ventilation (N = 104) previously enrolled in a randomized controlled trial of early occupational and physical therapy vs conventional therapy, which evaluated the end point of functional independence. Every patient had IIT and blinded muscle strength testing on hospital discharge to determine the incidence of clinically apparent weakness. The effects of insulin dose and early mobilization on the incidence of ICU-AW were assessed. RESULTS On logistic regression analyses, early mobilization and increasing insulin dose prevented the incidence of ICU-AW (OR, 0.18, P = .001; OR, 0.001, P = .011; respectively) independent of known risk factors for weakness. Early mobilization also significantly reduced insulin requirements to achieve similar glycemic goals as compared with control patients (0.07 units/kg/d vs 0.2 units/kg/d, P < .001). CONCLUSIONS The duel effect of early mobilization in reducing clinically relevant ICU-AW and promoting euglycemia suggests its potential usefulness as an alternative to IIT.

Abstract
PURPOSE Children with diabetes mellitus (DM) who develop acute appendicitis can present a diagnostic and clinical challenge. No studies have examined this population since the advent of multiple dose insulin therapy, computed tomography, and laparoscopic surgery. We sought to characterize these children to identify their differences and how to best care for them. METHODS We retrospectively examined the medical records of children with a preexisting diagnosis of DM treated for acute appendicitis. Values are presented as the mean±the standard error of the mean, and Student's t-test was used for statistical comparison. RESULTS We identified 18 diabetic children treated for acute appendicitis, making this the largest series of its kind. These children had similar presentations compared to non-diabetics, with the exception of often presenting without fever (83.3% with an initial temperature <38 C). All children developed significant postoperative hyperglycemia (average high 382±18mg/dL), and most had glycemic control for ≤50% of the hospitalization (14/18, 77.8%), but they otherwise had typical postoperative courses. CONCLUSIONS Diabetic children with appendicitis are often afebrile at presentation and have serum glucose levels that are difficult to control. Collaboration with pediatric endocrinologists is needed to appropriately manage these children during their hospitalization.

Abstract
BACKGROUND Recombinant human growth hormone (rhGH) increases protein synthesis, therefore it is used in burns with a total body surface area (TBSA) greater than 40%, where there is frequently an increase in protein breakdown and a decrease in protein synthesis. This change in protein metabolism correlates with poor wound healing of the burn and donor sites. OBJECTIVES To determine the effects of rhGH on the healing rate of burn wounds and donor sites in people with burns. SEARCH METHODS For this first update we searched the Cochrane Wounds Group Specialised Register (searched 04 September 2014); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 8); Database of Abstracts of Reviews of Effects (DARE) (The Cochrane Library 2014, Issue 3); Ovid MEDLINE (1950 to September Week 4 2014); Ovid MEDLINE (In-Process & Other Non-Indexed Citations September 8, 2014); Ovid EMBASE (1980 to 2014 Week 35); and EBSCO CINAHL (1982 to 8 September 2014). SELECTION CRITERIA Randomised controlled trials (RCTs) comparing rhGH with any comparator intervention, e.g. oxandrolone or placebo, in adults or children with burns. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, assessed trial quality and extracted data. The primary outcomes were the healing of the burn wound and donor sites and the occurrence of wound infections. The secondary outcomes were mortality rate, length of hospital stay, scar assessment, and adverse events: hyperglycaemia and septicaemia. MAIN RESULTS We included 13 RCTs (701 people). Six of the RCTs included only children aged 1 to 18 years and seven involved only adults (from 18 to 65 years of age). The mean TBSA of the included participants was greater than 49%. Twelve studies compared rhGH with placebo and one study compared rhGH with oxandrolone. Two trials found that compared with placebo, burn wounds in adults treated with rhGH healed more quickly (by 9.07 days; 95% confidence interval (CI) 4.39 to 13.76, I² = 0%). The donor site healing time was significantly shorter in rhGH-treated adults compared with placebo-treated participants (by 3.15 days; 95% CI 1.54 to 4.75, I² = 0%). Two studies in children with the outcome of donor site healing time could be pooled and the donor site healing time was shorter in the rhGH-treated children (by 1.70 days; 95% CI 0.87 to 2.53, I² = 0%). No studies reporting the outcome of wound infection were found. The incidence of hyperglycaemia was higher in adults during rhGH treatment compared with placebo (risk ratio (RR) 2.43; 95% CI 1.54 to 3.85), but not in children. Pooling the studies of adults and children yielded a significantly higher incidence of hyperglycaemia in the rhGH-treated participants (RR 2.65; 95% CI 1.68 to 4.16). AUTHORS' CONCLUSIONS There is some evidence that using rhGH in people with large burns (more than 40% of the total body surface area) could result in more rapid healing of the burn wound and donor sites in adults and children, and in reduced length of hospital stay, without increased mortality or scarring, but with an increased risk of hyperglycaemia. This evidence is based on studies with small sample sizes and risk of bias and requires confirmation in higher quality, adequately powered trials.

Abstract
Burn injury is a dramatic event with acute and chronic consequences including insulin resistance. However, factors associated with insulin resistance have not been previously investigated. The purpose of this study was to identify factors associated with long-term insulin resistance in pediatric burn injury survivors. The study sample consisted of 61 pediatric burn injury survivors 24 to 36 months after the burn injury, who underwent an oral glucose tolerance test. To assess insulin resistance, the authors calculated the area under the curve for glucose and insulin. The diagnostic criteria of the American Diabetes Association were used to define individuals with impaired glucose metabolism. Additional data collected include body composition, anthropometric measurements, burn characteristics, and demographic information. The data were analyzed using multivariate linear regression analysis. Approximately 12% of the patients met the criteria for impaired glucose metabolism. After adjusting for possible confounders, burn size, age, and body fat percentage were associated with the area under the curve for glucose (P < .05 for all). Time postburn and lean mass were inversely associated with the area under the curve for glucose (P < .05 for both). Similarly, older age predicted higher insulin area under the curve. The results indicate that a significant proportion of pediatric injury survivors suffer from glucose abnormalities 24 to 36 months postburn. Burn size, time postburn, age, lean mass, and adiposity are significant predictors of insulin resistance in pediatric burn injury survivors. Clinical evaluation and screening for abnormal glucose metabolism should be emphasized in patients with large burns, older age, and survivors with high body fat.

Abstract
OBJECTIVES Severe thermal injury is associated with extreme and prolonged inflammatory and hypermetabolic responses, resulting in significant catabolism that delays recovery or even leads to multiple organ failure and death. Burned patients exhibit many symptoms of stress-induced diabetes, including hyperglycemia, hyperinsulinemia, and hyperlipidemia. Recently, the nucleotide-binding domain, leucine-rich family (NLR), pyrin-containing 3 (NLRP3) inflammasome has received much attention as the sensor of endogenous "danger signals" and mediator of "sterile inflammation" in type II diabetes. Therefore, we investigated whether the NLRP3 inflammasome is activated in the adipose tissue of burned patients, as we hypothesize that, similar to the scenario observed in chronic diabetes, the cytokines produced by the inflammasome mediate insulin resistance and metabolic dysfunction. DESIGN Prospective cohort study. SETTING Ross Tilley Burn Centre & Sunnybrook Research Institute. PATIENTS We enrolled 76 patients with burn sizes ranging from 1% to 70% total body surface area. All severely burned patients exhibited burn-induced insulin resistance and hyperglycemia. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS We examined the adipose tissue of control and burned patients and found, via flow cytometry and gene expression studies, increased infiltration of leukocytes-especially macrophages-and evidence of inflammasome priming and activation. Furthermore, we observed increased levels of interleukin-1β in the plasma of burned patients when compared to controls. CONCLUSIONS In summary, our study is the first to show activation of the inflammasome in burned humans, and our results provide impetus for further investigation of the role of the inflammasome in burn-induced hypermetabolism and, potentially, developing novel therapies targeting this protein complex for the treatment of stress-induced diabetes.

Abstract
As a result of continuous development in the treatment of burns, the LD50 (the burn size lethal to 50% of the population) for thermal injuries has risen from 42% total body surface area (TBSA) during the 1940s and 1950s to more than 90% TBSA for young thermally injured patients. This vast improvement in survival is due to simultaneous developments in critical care, advancements in resuscitation, control of infection through early excision, and pharmacologic support of the hypermetabolic response to burns. This article reviews these recent advances and how they influence modern intensive care of burns.
