Abstract
BACKGROUND Total laryngectomy (TL) is a complex procedure, and patients undergoing TL are at high risk for readmission, which exposes them to hospital-acquired complications. Readmission rate is a metric for quality of care. We aimed to identify the rate, causes, and predictors of hospital readmission within 60 days after discharge following TL. METHODS This is a 12-year retrospective study where we included all patients undergoing TL in a single tertiary care center between 2008 and 2022. Patient charts were reviewed for demographics, comorbidities, and causes for readmission. RESULTS Of 83 patients who underwent TL, 12 (14.50%) were readmitted within 60 days. Common causes were surgical site infection (33.33%) and mucocutaneous fistula (25%). Significant predictors for readmission were tobacco use (P = 0.003), African ethnicity (P = 0.004), being unmarried (P < 0.001), lower preoperative serum albumin (P < 0.001), higher preoperative TSH (P = 0.03), higher preoperative neutrophil count (P = 0.035), higher American Society of Anesthesiology (ASA) score (P = 0.028), and higher Cumulative Illness Rating Scale (CIRS) score (P = 0.029). CONCLUSION One in every seven patients were readmitted following TL. Frequent causes include wound infection and fistulas. Predictors include preoperative hypoalbuminemia, hypothyroidism, African ethnicity, being unmarried, tobacco use, and a higher baseline burden of comorbidities. Such factors can be targeted to reduce hospital readmission rates.

Metabol Open 2023; 20:100255. [PMID: 38115863 PMCID: PMC10728564 DOI: 10.1016/j.metop.2023.100255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 09/01/2023] [Accepted: 09/10/2023] [Indexed: 12/21/2023] Open
Abstract
Introduction Drug-induced liver injury is the most common cause of acute liver failure. Off-Target effect "hepatotoxicity "frequently detected during clinical examination of patients on anti-Tb medication particularly isoniazid (INH), and rifampin (RMP). However, there is no any treatment option against isoniazid and rifampicin induced hepatotoxicity. It is, therefore, necessary to search for effective affordable and safe drugs from medicinal plants for the prevention of liver toxicity caused by isoniazid and rifampicin. The aim the current study is to evaluate hepatoprotective effect of hydro methanol extract from Otostegia integrifolia leaves in isoniazid and rifampicin-induced hepatotoxicity in Swiss albino mice. Methods O. integrifolia leaves powder was macerated in hydromethanol and thirty Swiss albino mice 29.0-40.6 g were grouped in to five groups. Group I were given 20 ml/kg distilled water, group II were given 100 mg INH and 150 mg RIF per kg body weight. Group III, group IV, and group V were given 200 mg extract, 400 mg extract, and 100 mg of N-acetyl cysteine respectively per kg 1hr before induction with 100 mg INH plus 150 mg RIF per kg. The treatments were followed for 14 days. On the 15th day, all mice were anaesthetized with diethyl ether; blood samples were collected for the assessment liver enzyme and function test. Results Group II mice's serum ALT, AST and total bilirubin levels were significantly increased and serum total protein and albumin levels were significantly decreased as compared with group I mice. The groups of mice treated with O. integrifolia at a dose of 400 mg/kg and N-acetyl cysteine AST, ALT and total bilirubin level were significantly decreased; and total protein and albumin levels were significantly (P < 0.05) increased as compared with group II. The liver index of the group IV showed decreased (P < 0.05) as compared to the group II. Conclusion Evidence from our study revealed that the hydromethanol extract of O. integrifolia has a hepatoprotective effect against isoniazid and rifampicin-induced hepatotoxicity in Swiss Albino mice. This protective effect of O. integrifolia extract may be based on its metal ion reducing power, free radical scavenging activity, and anti-inflammatory activity and could be used as a potential therapeutic option.

Abstract
There is an array of plasma protein alterations that occur in a wide variety of species, including humans in response to trauma, inflammation and infections, seemingly irrespective of etiologic agent. In numerous species, these plasma proteins are part of the innate immune response. In addition, it appears that a number of the plasma proteins in this array can be predictive of morbidity and/or mortality. We propose that based on historic use, selected acute phase proteins should be included in ongoing and future non-clinical and clinical studies to help us better understand disease progression in chronic, as well as acute diseases. In addition to assess if there is a relationship between vaccine-induced inflammation and degree of protection from live, attenuated or synthetic vaccines.

Abstract
Chemical modification of cellulose is currently attracting attention as researchers attempt to take advantage of the abundance of hydroxyl groups on its surface to introduce extra biological functionality. However, the possible deleterious effect of exposure to functionalized nanocellulose (CSN) remains a concern. Therefore, this study aims to explore the potential mechanisms of hepatotoxicity of CSN modified with oxalate ester (NCD) in rats. A 7-day repeated oral toxicity study of NCD at the doses of 50 and 100 mg kg−1body weight was conducted, and plasma and liver tissue samples were assayed using biochemical analysis, liver histopathology, and protein expression. NCD, at both doses, did not significantly ( p > 0.05) alter the relative weight of liver, alkaline phosphatase activity, and lipid peroxidation levels of the animals. However, NCD at the dose of 100 mg kg−1body weight significantly elevated aspartate aminotransferase, alanine aminotransferase, and myeloperoxidase activities. NCD also enhanced the immunohistochemical expression of inducible nitric oxide synthase and Bcl-2-associated X protein in the liver of rats. Histological observations revealed necrosis and severe cellular infiltration at the high-dose treatment. Our study provides an experimental basis for the safe application of NCDs.

Abstract
OBJECTIVES The presence of obesity may confound cholecalciferol dosing in vitamin D-deficient patients owing to potentially decreased bioavailability. The aim of this retrospective study was to evaluate cholecalciferol therapy in vitamin D-deficient, critically ill trauma patients with and without obesity. METHODS Adult patients with severe traumatic injuries who had a serum 25-hydroxyvitamin D (25-OH vit D) <50nmol/L were prescribed 10 000 IU of liquid cholecalciferol daily. Efficacy was defined as achievement of a 25-OH vit D of 75 to 200nmol/L. Safety was evaluated by the presence of hypercalcemia (serum ionized calcium >1.32 mmol/L). Fifty-three patients (18 obese, 35 non-obese) were identified for study. RESULTS Despite similar baseline concentrations (36 ± 7 versus 37 ± 7 nmol/L; P = NS), 25-OH vit D response was attenuated for those with obesity after 1 and 2 wk of cholecalciferol therapy (51 ± 18 versus 66 ± 27nmol/L, P < 0.01; 68 ± 19 versus 92 ± 25nmol/L, P < 0.01, respectively). Patients with obesity also tended to experience less hypercalcemia (22% versus 49% of patients, respectively) post-cholecalciferol therapy. CONCLUSION Obesity alters the response to cholecalciferol therapy in critically ill patients with severe traumatic injuries.

Abstract
Background and Aims Serum zinc, copper and selenium are measured in patients prior to commencing on parenteral nutrition; however, their interpretation can be difficult due to acute phase reactions. We assessed (i) the relationship of raised C-reactive protein with trace elements and albumin (ii) benefits of measuring trace elements when C-reactive protein is raised in patients requiring short-term parenteral nutrition. Methods Samples were collected for zinc, copper, selenium and albumin at baseline and then every two weeks and correlated with C-reactive protein results in patients on parenteral nutrition. Results were categorized into four groups based on the C-reactive protein concentrations: (i) <20 mg/L, (ii) 20-39 mg/L, (iii) 40-79 mg/L and (iv) ≥80 mg/L. Results In 166 patients, zinc, selenium and albumin correlated (Spearman's) negatively with C-reactive protein; r = -0.26, P < 0.001 (95% CI -0.40 to -0.11), r = -0.44, P < 0.001 (-0.56 to -0.29) and r = -0.22 P = 0.005 (-0.36 to -0.07), respectively. Copper did not correlate with C-reactive protein (r = 0.09, P = 0.25 [-0.07 to 0.25]). Comparison of trace elements between the four groups showed no difference in zinc and copper (both P > 0.05), whereas selenium and albumin were lower in the group with C-reactive protein > 40 mg/L ( P < 0.05). Conclusion In patients on short-term parenteral nutrition, measurement of C-reactive protein is essential when interpreting zinc and selenium but not copper results. Routine measurement of trace elements prior to commencing parenteral nutrition has to be considered on an individual basis in patients with inflammation.

Abstract
AIM Monoterpene glycosides derived from Paeonia lactiflora roots (Chishao) are believed to be pharmacologically important for the antiseptic herbal injection XueBiJing. This study was designed to characterize the pharmacokinetics and disposition of monoterpene glycosides. METHODS Systemic exposure to Chishao monoterpene glycosides was assessed in human subjects receiving an intravenous infusion and multiple infusions of XueBiJing injection, followed by assessment of the pharmacokinetics of the major circulating compounds. Supportive rat studies were also performed. Membrane permeability and plasma-protein binding were assessed in vitro. RESULTS A total of 18 monoterpene glycosides were detected in XueBiJing injection (content levels, 0.001-2.47 mmol/L), and paeoniflorin accounted for 85.5% of the total dose of monoterpene glycosides detected. In human subjects, unchanged paeoniflorin exhibited considerable levels of systemic exposure with elimination half-lives of 1.2-1.3 h; no significant metabolite was detected. Oxypaeoniflorin and albiflorin exhibited low exposure levels, and the remaining minor monoterpene glycosides were negligible or undetected. Glomerular-filtration-based renal excretion was the major elimination pathway of paeoniflorin, which was poorly bound to plasma protein. In rats, the systemic exposure level of paeoniflorin increased proportionally as the dose was increased. Rat lung, heart, and liver exposure levels of paeoniflorin were lower than the plasma level, with the exception of the kidney level, which was 4.3-fold greater than the plasma level; brain penetration was limited by the poor membrane permeability. CONCLUSION Due to its significant systemic exposure and appropriate pharmacokinetic profile, as well as previously reported antiseptic properties, paeoniflorin is a promising XueBiJing constituent of therapeutic importance.

Abstract
This retrospective study examined the validity of the commonly used serum albumin level as an indicator of nutrition status of patients with pressure ulcer(s), particularly because the serum albumin level is affected by various factors and may not be specific to malnutrition. Specifically, we investigated whether nutrition supply or inflammation affects the serum albumin level in 82 patients with pressure ulcers(s) (29 in whom pressure ulcer was present upon admission and 53 in whom pressure ulcer developed after hospital admission). Serum albumin levels, blood test including C-reactive protein (CRP) levels and blood count, caloric intake, and depth and healing of pressure ulcers were compared between various subgroups of patients. Serum albumin levels correlated with red blood cell counts and hemoglobin and CRP levels but not with caloric intake. The correlation with CRP before and after several weeks of pressure ulcer treatment was negative. The serum albumin level upon admission was higher in patients in whom the ulcer healed than in those in whom it did not heal as well as in patients who were discharged than in those who died in the hospital. The serum albumin level appears to reflect inflammation, wound healing, and disease severity rather than nutrition supply in patients with pressure ulcer. J. Med. Invest. 61: 15-21, February, 2014.

Abstract
Despite regular use of drugs for critically ill patients, overall data are limited regarding the impact of critical illness on pharmacokinetics (PK). Designing safe and effective drug regimens for patients with critical illness requires an understanding of PK. This article reviews general principles of PK, including absorption, distribution, metabolism, and elimination, and how critical illness can influence these parameters. In the area of drug absorption, we discuss the impact of vasopressor use, delayed gastric emptying and feeding tubes, and nutrient interactions. On the topic of drug distribution, we review fluid resuscitation, alterations in plasma protein binding, and tissue perfusion. With drug metabolism, we discuss hepatic enzyme activity, protein binding, and hepatic blood flow. Finally, we review drug elimination in the critically ill patient and discuss the impact of augmented renal clearance and acute kidney injury on drug therapies. In each section, we highlight select literature reviewing the PK impact of these conditions on a drug PK profile and, where appropriate, provide general suggestions for clinicians on how to modify drug regimens to manage PK challenges.

Abstract
OBJECTIVE Changes in serum albumin may reflect systemic immunoinflammation and hypermetabolism in response to insults such as trauma and sepsis. Esophagectomy is associated with a major metabolic stress, and the aim of this study was to determine if the absolute albumin level on the first postoperative day was of value in predicting in-hospital complications. METHODS A retrospective study of 200 patients undergoing esophagectomy for malignant disease at St. James Hospital between 1999 and 2005 was performed. Patients who had pre and postoperative (days 1, 3, and 7) serum albumin levels measured were included in the study. Patients were subdivided into three postoperative albumin categories <20 g/l, 20-25 g/l, >25 g/l. Logistic regression analysis was performed to calculate the odds of morbidity and mortality according to the day 1 albumin level. RESULTS Patients with an albumin of less than 20 g/l on the first postoperative day were twice as likely to develop postoperative complications than those with an albumin of greater than 20 g/l (54 vs 28% respectively, p < 0.011). Correspondingly, these patients also had a significantly higher rate of Adult Respiratory Distress Syndrome (22 vs 5%, p < 0.001), respiratory failure (27 vs 8%, p < 0.01) and in-hospital mortality (27 vs 6% (p < 0.001). On multivariate logistic regression analysis, day 1 albumin level was independently related to postoperative complications (odds ratios, 0.89: 95%; confidence intervals, 0.83-0.96; p < 0.005). In addition, albumin <20 g/l on the first postoperative day was associated with the need for further surgery and a return to ICU. CONCLUSION Serum albumin concentration on the first postoperative day is a better predictor of surgical outcome than many other preoperative risk factors. It is a low cost test that may be used as a prognostic tool to detect the risk of adverse surgical outcomes.

Clin Nutr 2006; 25:681-6. [PMID: 16698136 DOI: 10.1016/j.clnu.2005.12.011] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2004] [Revised: 12/24/2005] [Accepted: 12/25/2005] [Indexed: 12/23/2022]
Abstract
BACKGROUND Early feeding after injury has been suggested to decrease morbidity and mortality in many studies. Intrajejunal feeding has been preferred over intragastric feeding due to earlier return of peristalsis following laparotomy. Few reports, however, have focused on the tolerance and change in pH inside the stomach after intragastric and intrajejunal feeding. The aim of the present study was the assessment of (1) the postoperative tolerance of intragastric and intrajejunal feeding, and (2) the effect of intragastric and intrajejunal feeding on intragastric pH value. MATERIALS AND METHODS From April 1998 to October 2002, 140 patients underwent colon resection for colorectal cancer entered the study. The patients were divided into seven groups of 20 patients each. Group I was kept on NPO for 1 week. Groups II, III, and IV were fed through a nasogastric (NG) tube from the second to the sixth postoperative day (POD) with low residual (Osmolite-HN), high-fat (Pulmocare), and glutamine-containing (AlitraQ) enteral formulas, respectively. Groups V, VI, and VII were fed through a nasojejunal (NJ) tube from the second to the sixth POD with Osmolite-HN, Pulmocare, and AlitraQ, respectively. Feeding started at 500 kcal/500 cm(3)/d. If the patient tolerated the formula well, feeding increased to 1,500 kcal/1,500 cm(3)/d the following day. Intragastric pH was measured preoperatively and then twice daily until the sixth POD. RESULTS Poor tolerance occurred in 14 patients (23%) with NG tube feeding and 18 patients (30%) with NJ tube feeding. The pH value of intragastric juice increased significantly once NG feeding started (3.67+/-1.33 on the third POD; 4.28+/-1.26 on the sixth POD). However, the pH value remained low after NJ feeding was started (2.09+/-1.46 on the third POD; 2.14+/-1.49 on the sixth POD). CONCLUSIONS This series suggests that (1) the majority of patients can tolerate early feeding well following resection of colorectal cancer, and NJ feeding is not necessarily better tolerated than NG feeding; (2) early NG, but not the NJ feeding, can significantly elevate the intragastric pH value in patients who underwent resection of colorectal cancer. NG may be more effective than NJ feeding in preventing stress-induced gastropathy by elevating the pH value of intragastric juice.

Abstract
In acute-phase response, the use of amino acids is redirected to supporting the synthesis of proteins for host defence and tissue repair. Fibrinogen is one of these proteins, and its plasma levels commonly increase in acute-phase conditions. After hepatectomy, this pattern may be modified by the variable impact of postoperative liver dysfunction. Our study was performed to specifically assess and quantify this aspect. Data were collected prospectively on 82 hepatectomized patients; 62 recovered normally, 20 had major complications (most commonly sepsis). Plasma fibrinogen and a large series of complementary variables were determined preoperatively and at postoperative days 1, 3 and 7 in all patients and until recovery, or death in those with complications. Multiple regression analysis showed that postoperative changes in fibrinogen (deltaFIB, micromol/l) were simultaneously related to the number of resected liver segments (NSEG), total bilirubin (BIL, micromol/l), aspartate aminotransferase (AST, U/l, n.v. 5-45), albumin (ALB, g/l), prothrombin activity (PA, % of standard reference), age (AGE, years) and basal preoperative fibrinogen (PFIB, micromol/l): deltaFIB = -0.51(NSEG) - 0.71(Log(n)BIL) - 0.74(Log(n)AST) + 0.11(ALB) + 0.09(PA) - 0.06(AGE) - 0.55(PFIB) + 7.74 (n=362, r2=0.68, p<0.001). In addition, an early postoperative tendency for low fibrinogen was associated with the subsequent development of complications or death. Our study quantifies the impact of size of hepatectomy and dysfunction of residual liver in modulating postoperative fibrinogen level and suggests that failure of fibrinogen to increase may signal an unfavorable condition limiting up-regulation of acute-phase response and increasing liability to complications.

Abstract
Serum hepatic protein (albumin, transferrin, and prealbumin) levels have historically been linked in clinical practice to nutritional status. This paradigm can be traced to two conventional categories of malnutrition: kwashiorkor and marasmus. Explanations for both of these conditions evolved before knowledge of the inflammatory processes of acute and chronic illness were known. Substantial literature on the inflammatory process and its effects on hepatic protein metabolism has replaced previous reports suggesting that nutritional status and protein intake are the significant correlates with serum hepatic protein levels. Compelling evidence suggests that serum hepatic protein levels correlate with morbidity and mortality. Thus, serum hepatic protein levels are useful indicators of severity of illness. They help identify those who are the most likely to develop malnutrition, even if well nourished prior to trauma or the onset of illness. Furthermore, hepatic protein levels do not accurately measure nutritional repletion. Low serum levels indicate that a patient is very ill and probably requires aggressive and closely monitored medical nutrition therapy.

Abstract
Albumin is an abundant plasma protein with multiple physiologic functions, and low serum albumin levels have been associated with increased mortality in hospitalized patients. In a retrospective matched-pair study, we investigated whether emergency department (ED) albumin levels predict delayed mortality for patients initially stabilized after blunt trauma. Fifty-one hospital non-survivors who died more than 24 h after admission to a trauma center ED were matched by Injury Severity Score, type and location of injury, age, and gender with 51 survivors. All patients had serum albumin levels determined upon arrival in the ED. The non-survivors had a significantly lower admission albumin of 3.1 g/dL compared to 3.5 g/dL for survivors. Patients with albumin levels < 3.4 g/dL were 2.5 times more likely to die compared to patients with normal albumin levels. These preliminary results indicate that initial hypoalbuminemia in blunt trauma patients is an independent predictor of delayed mortality, suggesting that these patients require continued clinical vigilance and an aggressive search for evolving complications.

Abstract
OBJECTIVE We investigated the metabolic effects of intravenous nutrition through a portal (PN) or systemic (SN) peripheral vein. METHODS Twenty patients were randomized to receive PN or SN nutrition after colorectal surgery. The daily regimen included 900 kcal and 100 g of amino acid (AA). Visceral proteins and hepatic enzymes were measured on days 0, 1, 3, 5, and 7, and plasma arterovenous differences and limb flux of AA were measured on days 0, 3, and 7; urinary nitrogen and 3-CH3-histidine were analyzed daily. RESULTS Serum albumin on day 7 was still depressed (P = 0.01) in SN and fully restored in PN patients. Prealbumin levels increased significantly (P = 0.05) in the PN group only. Plasma levels of glutamine and asparagine were higher in PN than in SN patients, and this difference was statistically significant (P = 0.05). SN patients had significantly more negative limb-muscle balance of valine and tyrosine, whereas PN patients had a higher muscle release of citrulline and taurine. CONCLUSIONS In conclusion, short-term PN is safe and has some metabolic benefits: it accelerates recovery from postoperative hypoalbuminemia and hypopnealbuminemia and is associated with a higher plasma level of glutamine and an AA plasma pattern that is closer to normal. PN blunts the catabolic response of the muscle, decreasing loss of proteins and release of some AA involved in hepatic gluconeogenesis.

Abstract
Lipopolysaccharide-binding protein (LBP) is an important modulator of the host's response to endotoxin. In a previous study, we found evidence for the synthesis of LBP by intestinal epithelial cells. In this study, we explored the polarity of LBP secretion by these cells. Polarized monolayers of Caco-2 cells were used as intestinal mucosa model. Cells were stimulated apically or basally with cytokines, and LBP secretion was analyzed. Furthermore, the presence of LBP in intestinal mucus of healthy and endotoxemic mice was studied using a mucus-sampling technique. The constitutive unipolar LBP secretion from the apical cell surface was markedly enhanced when cells were exposed to cytokines at their apical surface. However, bioactive LBP was secreted from both cell surfaces after basolateral stimulation of cells. Cytokines also influenced the secretion of the acute phase proteins serum amyloid A, apoA-I, and apoB from both surfaces of Caco-2 cells. Furthermore, transport of exogenous LBP from the basolateral to the apical cell surface was demonstrated. In line with these in vitro data, the presence of LBP in intestinal mucus was strongly enhanced in mice after a challenge with endotoxin. The results indicate that LBP is present at the mucosal surface of the intestine, a phenomenon for which secretion and transport of LBP by intestinal epithelial cells may be responsible.

Abstract
Studies have suggested that early feeding after injury decreases morbidity and mortality. Few reports, however, have focused on the change in pH inside the stomach after early tube feeding. The aim of the present study was the assessment of 1) the change in intragastric pH after surgery, and 2) the effect of early nasogastric tube feeding on intragastric pH value. From April 1997 to February 1998, 80 patients who underwent colon resection for colorectal cancer by a single surgeon entered the study and were randomized into four groups. Twenty patients (group I) were kept on NPO for 1 wk, and 20 patients per group (groups II, III, and IV) were fed through a nasogastric tube from the second to the seventh postoperative day with low-residual (Osmolite HN), high-fat (Pulmocare), and glutamine-containing (AlitraQ) enteral formulas. Feeding started at 500 kcal/500 cc/d. If the patient tolerated the formula well, feeding increased to 1500 kcal/1500 cc(-1)/d(-1) the following day. Intragastric pH was measured preoperatively and then twice daily until the sixth postoperative day. The pH value of intragastric juice increased significantly once feeding started (3. 67 +/- 1.33 on the third postoperative day; 4.28 +/- 1.26 on the six postoperative day). The pH value seemed only mildly affected by the patient's tolerance for tube feeding (poorly tolerated group, pH 3. 52 +/- 1.75 versus 3.75 +/- 1.21 in the well-tolerated group on the third postoperative day; poorly tolerated group, pH 3.67 +/- 1.02 versus 4.45 +/- 1.27 in the well-tolerated group on the sixth postoperative day). The pH value of intragastric juice was higher in group II than in groups III and IV (4.51 +/- 1.57, 3.90 +/- 1.20, 4. 42 +/- 0.89 respectively, on the sixth postoperative day). This series suggests that early nasogastric feeding can significantly elevate the intragastric pH value in patients after resection of colorectal cancer. Nasogastric feeding may decrease the incidence of stress ulceration by elevating the pH value of intragastric juice.

Abstract
BACKGROUND Actin is the dominating protein in mammalian cells. Release of excessive amounts of actin into the circulation may result in a condition resembling multiple organ failure. The purpose of this study was to determine if admission levels of Gc-globulin can predict survival after multiple trauma. Also, we wanted to compare the predictive ability of Gc-globulin with that of the TRISS-Like scoring system. METHODS Fifty-seven patients with a median ISS 18 (16-75) were included. All patients had a blood sample taken median 42 min after the injury (19-110 min). Serum Gc-globulin was measured by rocket immunoelectrophoresis. RESULTS On admission, all patients had significantly reduced levels of Gc-globulin compared with normal controls. Gc-globulin was significantly higher in the group of survivors (n = 41), compared with non-survivors (n = 16). Median 237 mg/l vs. 188 mg/l (P < 0.01). The predictive ability of Gc-globulin regarding death was similar to that of TRISS-Like with positive predictive values of 69%, a negative predictive value of 84%, a sensitivity of 56% and a specificity of 90%. CONCLUSIONS The predictive value of Gc-globulin regarding survival was similar to that of an established scoring system. Gc-globulin, alone or in combination with other parameters, may serve as a routine tool for early identification of patients at risk after severe injury, increasing the possibility of early intervention.

Abstract
Plasma levels of visceral proteins (VP) are commonly used for evaluation of nutritional status. Low values observed in burn patients are caused by several factors including microvascular hyper-permeability and inflammatory processes. The aim of the study was to define a range of standard values specific to burn patients. Retrospective review: from days post-burn 12 to 43, four VP and three acute phase reactants (APR) were measured twice a week, in the plasma of 107 burn patients. From these data, standard' values were determined in respect with burn surface area (BSA) and post-burn time. The results were that the VP increase and APR decrease linearly during the study. Correlation between plasma proteins and BSA or post-burn day, change from protein to protein. Albumin and transferrin are less sensitive than prealbumin and especially retinol binding protein to variations of APR, but transferrin lacks of specificity. The conclusion of the study was that plasma levels of VP have to be compared to reference standard values. When levels lower than theoretical values are observed, simultaneous APR values (especially C reactive protein) have to be compared to their own reference standard, in order to separate nutritional from inflammatory effects.

Abstract
BACKGROUND We wanted to determine if achievement of energy balance decreases myofibrillar protein catabolism and nitrogen loss during posttraumatic catabolic illness. METHODS Surgical intensive care unit of a level I trauma center in a university medical center. Trauma patients expected to be mechanically ventilated for at least 4 days were randomly assigned to one of three parenteral feeding groups: (1) nonprotein calorie group: dextrose and lipid intake equal to measured energy expenditure; (2) total calorie group: dextrose, lipid, and protein intake equal to measured energy expenditure; and (3) hypocaloric group: dextrose and lipid intake equal to 50% of measured energy expenditure. Target protein intake for all groups was 1.7 g/kg body wt. On day 4 of nutrition support, a 24-hour balance study was conducted. Urine urea and total nitrogen production, 3-methylhistidine excretion, energy expenditure, and substrate utilization were measured. RESULTS Despite significant differences in nonprotein and total calorie balance among the groups, nitrogen loss, nitrogen balance, and catabolic rate were not significantly different. Nitrogen loss correlated with catabolic rate but not with energy expenditure or energy balance. Catabolic rate was associated with energy expenditure but not with energy balance. Nitrogen loss was positively correlated with the percentage of nonprotein energy expenditure met by nonprotein calorie intake. CONCLUSIONS Achievement of energy balance (nonprotein or total energy) failed to decrease catabolic rate or nitrogen loss acutely in multiple trauma patients. Provision of caloric intake equal to energy expenditure does not seem necessary during the acute phase of posttraumatic catabolic illness.

Abstract
BACKGROUND One of the major components of the metabolic response to severe trauma is the alteration in concentrations of a large number of plasma proteins referred to as acute-phase proteins (APP). The principle mediators of these liver-synthesized APP are mainly the cytokines interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha). METHODS We have measured the plasma levels of IL-6, TNF alpha, and 20 APP in 24 adult, severely injured, hypermetabolic and highly catabolic patients with multiple injuries within 48-60 hours after injury, when they were receiving maintenance fluids without calories or nitrogen, and subsequently during 7 days of total parenteral nutrition with (n = 12) or without (n = 12) recombinant human growth hormone supplementation (rhGH, 0.15 mg/kg/d). RESULTS Baseline positive APP due to severe trauma include C-reactive protein (CRP), alpha-1 antichymotrypsin, alpha-1 acid glycoprotein, alpha-1 antitrypsin, fibronectin, and factor B. Negative APP include IgG, IgM, complement-3, prealbumin, transferrin, ceruloplasmin, and albumin. Except for CRP, alpha-1 antichymotrypsin, and albumin, all the APP levels increase during 7 days of nutritional support. Plasma levels of cytokines IL-6 and TNF-alpha, although initially markedly increased after injury, decrease with parenteral refeeding. There is a linear correlation between CRP and IL-6 levels and also between the transport proteins prealbumin and transferrin. Trauma-induced increases in CRP and IL-6 levels decreased with nutrition alone, but did not change with rhGH supplementation. An immunosuppressed state of injury is evident from the decreased immunoglobulin levels (IgG, IgM, IgA) in the trauma patients. Total parenteral nutrition alone increases the immunoglobulin levels to normal. However, with adjuvant rhGH, only IgA levels are normalized. CONCLUSIONS Adjuvant rhGH therapy does not attenuate the reprioritization of acute liver protein synthesis and results in only limited restoration of host defenses. The clinical implications of these findings await further study.

Abstract
Comprehensive care of patients in hospitals includes assessment of nutritional status and provision of appropriate support. This approach is facilitated by knowledge of the essential differences in metabolism between starved and stressed states. Nutritional assessment and care of patients in a hospital are based on answers to the following questions: Who gets it? When do they get it? How much do they get? What route is used to administer it? What kind do they get? What are common complications of enteral and parenteral support? What nutritional aspects are pertinent to common diseases?

Abstract
BACKGROUND Hypothermia exacerbates coagulopathy and is thus a potentially devastating morbidity during operative debridement of burn wounds. Current techniques for maintaining body temperature include warming intravenous fluids at 38 degrees C. The purpose of this study was to assess the safety of infusing saline heated to 55-60 degrees C. METHODS Using a modified fluid warmer, saline heated to 60 degrees C was infused through central venous access in eight adult patients undergoing debridement of burn wounds. The temperature of the saline actually entering the patient was measured by a thermocouple attached at the connection to the central line catheter. RESULTS The actual infusate temperature was 54.0 +/- 1.2 degrees C. Over the first hour, 1,100 mL of hot saline was given, thus delivering 17.6 kcal more heat than fluid warmed to the traditional 38 degrees C. Core temperature measured via esophageal and Foley catheters had an insignificant trend toward increase during the operative procedure. There was no evidence of intravascular hemolysis or coagulopathy. CONCLUSION This pilot study suggests that infusion of hot crystalloids given via central venous access is safe and may be an acceptable adjuvant in attenuating hypothermia during operative procedures.

Abstract
PURPOSE Many patients with sepsis require surgery for their management, often on an urgent or emergency basis. Anaesthetists are commonly required to manage patients with sepsis and septic shock in the operating room, past anaesthesia recovery area, and the intensive care unit. Since little has been written in the Anaesthesia literature on sepsis and septic shock, a review of this topic was considered appropriate. SOURCE References were obtained from computerized searches on the National Library of Medicine (English language), recent review articles and personal files. PRINCIPLES FINDINGS: Septic shock is a common cause of morbidity and mortality. Its presentation may be subtle or catastrophic. Successful management depends on an understanding of the pathophysiology of the syndrome, allowing rapid, appropriate resuscitation. This often requires aggressive correction of volume deficit, maintenance of adequate perfusion pressure with inotropic and vasopressor therapy, mechanical ventilation and correction of coagulopathy. Appropriate cultures must be taken and antibiotic therapy started, often empirically. Anaesthetic management should include careful haemodynamic monitoring. Anaesthesia induction and maintenance must be tailored to the haemodynamically unstable patient. CONCLUSIONS The management of the septic patient in the perioperative period presents a challenge for the anaesthetist. Haemodynamic and respiratory instability should be anticipated. Management requires multisystem intervention and careful anesthetic management.

Abstract
Blood [base excess] ([BE]) is defined as the change in [strong acid] or [strong base] needed to restore pH to normal at normal PCO2. Some believe that [BE] is unhelpful because [BE] may be elevated with a "normal" [strong ion difference] ([SID]), where a strong ion is one that is always dissociated in physiological solution, and where [SID] = [strong cations]-[strong anions]. Using a computer simulation, the hypothesis was tested that [SID] = [SID Excess] ([SIDEx]), where [SIDEx] is the change in [SID] needed to restore pH to normal at normal PCO2. The most current version of the plasma [SID] ([SID]p) equation was used as a template, and an [SIDEx] formula, of the Siggaard-Andersen form, derived: [SIDEx]p = [HCO3-]p -24.72 + (pHp - 7.4) x (1.159 x [alb]p + 0.423 x [Pi]p). [SID] was compared to [SIDEx] over the physiologic range of plasma buffering, and it was found that [SIDEx] varied by approximately 15 mM at any given [SID], thereby faulting the hypothesis. It is concluded that [SID] can be "normal" with an elevated [SIDEx], the latter being an expression of the [BE] concept, and a more helpful quantity in physiology. The "metabolic" component of a given acid-base disturbance is usually estimated as whole blood [base excess] ([BE]WB), where [BE]WB is defined as the change in [strong acid] or [strong base] needed to restore plasma pH (pHp) to 7.4 at PCO2 of 40 Torr. However, the [BE] approach has been criticized as "inadequate for interpretation of complex acid-base derangements such as those seen in critically ill patients." The proposed alternative is the strong ion difference (SID) method, where a strong ion is one that is always dissociated in solution, and where [SID] = [strong cations] - [strong anions]. On the one hand, it does not seem possible, by the definitions of these entities, to change [SID] without also changing [BE]. On the other hand, a selected group of critically ill patients with hypoproteinemia has been reported in whom [SID] was "normal" (i.e. approximately 40 mEq.l-1) but [BE]WB clearly increased. The idea was that hypoproteinemia caused the alkalosis, due to a deficiency of plasma weak acid buffer, necessitating increased [HCO3-]p to maintain electrical neutrality. How could [SID] be "normal," but [BE] increased? The purpose of the current exercise was to address this question. An [SID excess] ([SIDEx]) formula was developed, conceptually identical to Siggaard-Andersen's [BE], and [SID] was compared to [SIDEx] over the physiological range of plasma [albumin] ([alb]p), plasma [phosphate] ([Pi]p), and plasma pH (pHp).

Abstract
BACKGROUND The effects of glutamine-enriched total parenteral nutrition (TPN) solution on survival, and protein turnover in the whole body and in individual organs were investigated in a rat protracted peritonitis model. METHODS Twenty-three rats underwent venous catheter insertion. Osmotic pumps were implanted in the peritoneal cavity to allow continuous delivery of Escherichia coli (4 x 10(8) CFU/d). The conventional TPN group received a conventional amino acid solution. The Ala-Gln TPN group received an alanyl-glutamine-enriched TPN solution. The two TPN solutions were isocaloric and isonitrogenous. RESULTS Over the 5 days of TPN treatment, the survival rate of the Ala-Gln group was significantly higher than that of the conventional group. The Ala-Gln group tended to have increased whole-body protein turnover compared with the conventional group. Fractional protein synthetic rates (FSR) in the liver and gastrocnemius muscle of the Ala-Gln group were significantly higher than those of the conventional group. The serum glutamine concentration correlated positively with the FSR of both liver and muscle. The Ala-Gln group showed significantly greater mucosal height and mitoses per crypt, in the small intestine, than did the conventional group. CONCLUSIONS Our results suggested that, in comparison with standard glutamine-free TPN, Ala-Gln-supplemented TPN increases protein synthesis in the liver and skeletal muscle, protects the morphology of the intestinal mucosa, and improves survival in protracted bacterial peritonitis. Ala-Gln supplementation may be useful in septic patients.

Abstract
OBJECTIVE To develop a quantitative severity stratification within the framework of a Physiologic State Classification (PSSC) system that can be applied to critically ill post-trauma patients with "sepsis/SIRS" and to relate PSSC to the nature of the plasma cytokine response. MATERIALS AND METHODS At each study time period, a patient was classified into one of seven physiologic States previously derived from clustering 17 cardiopulmonary and metabolic variables from 338 critically ill patients: R = reference, A = normal stress response, B = metabolic insufficiency, C1 (early) and C2 (late) = respiratory insufficiency, D = cardiogenic insufficiency, H = nonshock hypovolemia. MAIN RESULTS The PSSC used State data from a developmental set of 159 trauma patients in a logistic model (L2PDEATH) to provide a quantitative index of severity. This severity index was tested on 80 new trauma patients (mean injury Severity Score (ISS) = 27.6, 64% survivors). Using PSSC State distributions for evaluation of enzyme-linked immunosorbent assay (ELISA) measured cytokines interleukin (IL)-1, IL-6, IL-8, tumor necrosis factor (TNF) showed the multicytokine score to be greatest in those C2- and B-State regions associated with a higher severity as measured by L2PDEATH. Compared with ARDEATH of the Acute Physiology and Chronic Health Evaluation (APACHE) II scoring system, L2PDEATH provided a better indicator of severity of sepsis/systemic inflammatory response syndrome (SIRS) for posttrauma patients. CONCLUSIONS PSSC allows classification of the physiologic and cytokine mediator response to trauma and permits stratification of severity in posttrauma critical illness.

Abstract
The title of this article is taken from an interesting Letter to the Editor entitled 'Artificial liver support-Pipe dream or reality' by Cattral and Levy of the Toronto Hospital, Canada, published in the New England Journal of Medicine 1994, in which the authors persuasively propose possibilities of artificial liver support and suggest its advantages. We find that their suggestions agree with the core of our thoughts on this subject. The present article deals with the concept of implanting livers taken from humans, primates or non-primates (e.g. hog) into patients in parallel with their own metabolically fatigued or cirrhotic livers, with minimal surgical manipulation, as a prelude to total artificial liver support via a liver dialysis device. While the possibility exists that the host liver may recover function, a donor liver, whether implanted into the patient's abdomen or connected in vitro to the patient's circulatory system extracorporeally, may provide the host liver respite and a period for recovery and proliferation, if possible. Once recovery is under way, the donor liver may be removed and the patient will not experience the usual risks of rejection and the necessary side-effects of immunosuppression associated with conventional full hepatectomy and donor transplantation. The viability of a liver implantation model in rats is correlated in this article with hepatic acute phase response.

Abstract
The hepatic capacity for acute phase protein synthesis after partial hepatectomy in the elderly patients was prospectively studied. Forty-one patients who consecutively underwent a partial hepatectomy were grouped according to age of greater or less than 70 years; 12 were in the older group and 29 in the younger. The changes in the levels of serum interleukin-6, alpha 1-antitrypsin, alpha 1-acid glycoprotein, haptoglobin, and plasma fibrinogen were measured after surgery. The postoperative changes in standard liver function tests were also measured. The incidence of postoperative infected complications was 25% in the older group and 7% in the younger (P = 0.28). Although postoperative levels of serum interleukin-6 were similar between the two groups, those of serum alpha 1-antitrypsin, alpha 1-acid glycoprotein, and haptoglobin were significantly lower in the elderly (P < 0.05). Postoperative levels of serum alpha 1-antitrypsin and plasma fibrinogen showed an increase of about 30% compared with the preoperative values (P < 0.05) in the younger group, but no significant increase in the older. Postoperative deterioration of serum albumin levels and hepaplastin test values was also significantly more severe in the older group (P < 0.05). We conclude that in the older patients, a reduction of acute phase protein synthesis occurs after partial hepatectomy as a result of a global deterioration of liver function, and may render patients liable to infection.

Abstract
The aim of this study was to investigate nutritional status and protein metabolism during total parenteral nutrition (TPN) in AIDS patients with weight loss. Six patients on treatment for AIDS-associated complications were investigated and reviewed TPN that supplied energy equivalent to 1.5 times the resting energy expenditure (REE). Amino acid (AA) supply increased from 0.6 g/kg body weight (BW)/d on days 1 to 3 and 1.2 on days 4 to 6 to 1.8 on days 7 to 9. Nonprotein energy was given as equicaloric amounts of glucose and fat emulsion. There were repeated measurements of nitrogen balance and whole-body protein turnover (WBPT) using a bolus 15N-glycine method on the morning of days 3, 6, and 9. Principal findings were as follows: (1) increasing the supply of AAs significantly improves nitrogen balance in AIDS patients; (2) there is no simple linear effect of increasing amounts of AAs on WBPT in AIDS patients; (3) WBPT is high and variable in these patients; and (4) mean WBPT of each patient is significantly correlated with body cell mass (BCM) as a proportion of BW (P < .001, r = .92). We conclude that poor nutritional status in AIDS patients with weight loss is associated with high WBPT. However, these patients can attain at least transiently positive nitrogen balance with sufficient protein intake, predominantly through an increase in whole-body protein synthesis (WBPS).

Abstract
This review addresses some of the challenges confronting the modern nutrition support clinician in developing protocols for nutrition assessment. While it is generally agreed upon that patients who are malnourished are at greater risk for development of complications during hospitalization, there is no consensus on the best method for assessment of nutritional status. Assessment parameters currently available include clinical, biochemical, anthropometric, and functional tests designed to evaluate nutrition status as well as estimate body composition. As some of these parameters are expensive or not practical for routine clinical use, they should be evaluated carefully when a nutrition assessment protocol is designed.

Abstract
A pattern of multiple organ dysfunction syndrome (MODS) and risk factors following blunt trauma was identified, based on analyses of clinical data from 3611 patients who were admitted directly to a level I trauma centre and had hospital stays > or = 3 days. Five system dysfunctions were simultaneously associated (P < 0.05) with death (adjusted odds ratio): adult respiratory distress syndrome (ARDS) (4.9), renal failure (6.7), hyperglycaemia (3.6), recurrent acidosis (4.8) and hypoalbuminaemia (1.8). Mortality increased with the number of system dysfunctions. For the 336 patients with MODS (> or = 2 dysfunctions), mortality was 32.4 per cent compared with 1.3 per cent in the non-MODS group (P = 0.0001). Of the 254 with MODS occurring within 72 hours, mortality was 27 per cent compared with 49 per cent in those manifesting MODS later (P < 0.001). The 175 (52.1 per cent) with organ failure (renal failure and/or ARDS) also had metabolic dysfunction. Seven admission risk factors were independently associated (P < 0.003) with MODS [adjusted odds ratio]: pre-existing condition (3.4), age > 50 (3.1), Injury Severity Score > or = 25 (6.4), hypotension (2.8), acidaemia (2.2), 24 h blood loss > 1 l (3.7), and major base deficit (1.6). Only 13 per cent with MODS had an infection in the 5 days before or at initiation of MODS. Haemodynamic instability, acidosis, blood loss, pre-existing condition, age and serious injury were risk factors independently related to life-threatening MODS, but infection was an uncommon precursor except in late MODS.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
BACKGROUND Experimental reports have indicated that hepatic oxidative and synthetic metabolism may become depressed in sepsis. Because the mechanism of infection-related liver dysfunction has not been established, further study of these functional alterations could contribute to the therapeutic management of septic organ failure syndromes. However, recently controversy has arisen over the existence of these derangements that must be reconciled before further progress in this field can be made. METHODS Splanchnic balance studies for the measurement of glucose output and oxygen consumption were used to assess hepatic function in fasted normal volunteers (n = 18), injured patients (n = 10), and patients with sepsis (n = 18). The liver's contribution to splanchnic metabolism was estimated from a comparison of splanchnic oxygen utilization in response to increases in the liver-specific process of glucogenesis. In addition, in vivo liver albumin production was determined by using the [14C] carbonate technique. RESULTS Glucose output after injury and sepsis was increased by 12.8% and 76.6%, respectively, compared with controls. On the basis of substrate balance studies, gluconeogenesis was estimated to account for 46%, 87%, and 93%, respectively, of splanchnic glucose output in each of the three groups. In patients with sepsis glucose output was also noted to be linearly related to regional oxygen consumption, indicating that these processes were coupled and increases in the respiratory activity of the splanchnic cellular mass could be accounted for by increases in new glucose output and gluconeogenic substrate clearance. The mean albumin synthetic rate increased during injury and sepsis by 22% and 29%, respectively, compared with normal volunteers. CONCLUSIONS These studies cast doubt on the commonly held notion that tissue respiratory dysfunction may occur during sepsis. On the contrary, hepatic function is accelerated during hyperdynamic sepsis, and evidence indicating oxidative or synthetic functional depression is lacking.
