[PMID: 38674881 PMCID: PMC11053507 DOI: 10.3390/nu16081191] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 04/03/2024] [Accepted: 04/16/2024] [Indexed: 04/28/2024] Open
Abstract
Anorexia nervosa (AN) induces organ dysfunction caused by malnutrition, including liver damage leading to a rise in transaminases due to hepatocyte damage. The underlying pathophysiology of starvation-induced liver damage is poorly understood. We investigate the effect of a 25% body weight reduction on murine livers in a mouse model and examine possible underlying mechanisms of starvation-induced liver damage. Female mice received a restricted amount of food with access to running wheels until a 25% weight reduction was achieved. This weight reduction was maintained for two weeks to mimic chronic starvation. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were measured spectrophotometrically. Liver fat content was analyzed using an Oil Red O stain, and liver glycogen was determined using a Periodic acid-Schiff (PAS) stain. Immunohistochemical stains were used to investigate macrophages, proliferation, apoptosis, and autophagy. Starvation led to an elevation of AST and ALT values, a decreased amount of liver fat, and reduced glycogen deposits. The density of F4/80+ macrophage numbers as well as proliferating KI67+ cells were decreased by starvation, while apoptosis was not altered. This was paralleled by an increase in autophagy-related protein staining. Increased transaminase values suggest the presence of liver damage in the examined livers of starved mice. The observed starvation-induced liver damage may be attributed to increased autophagy. Whether other mechanisms play an additional role in starvation-induced liver damage remains to be investigated.

J Surg Res 2024; 296:123-129. [PMID: 38277947 DOI: 10.1016/j.jss.2023.12.028] [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: 07/27/2023] [Revised: 12/03/2023] [Accepted: 12/28/2023] [Indexed: 01/28/2024]
Abstract
INTRODUCTION Cholinesterase is a classical marker that reflects nutritional and inflammatory status. The aim of the present study was to evaluate the association between serum cholinesterase levels and postoperative infectious complications in patients undergoing gastrectomy for gastric cancer. MATERIALS AND METHODS This retrospective study comprised 108 patients who underwent gastrectomy for gastric cancer. We comprehensively investigated the association between clinicopathological variables and postoperative infectious complications after gastrectomy. Then patients were divided into the cholinesterase-high and -low groups to analyze their clinicopathological variables. Finally, we analyzed the types of infectious complications that were most associated with preoperative serum cholinesterase levels. RESULTS Twenty-six patients (24%) developed postoperative infectious complications. Multivariate analysis revealed that serum cholinesterase levels (P = 0.026) and N stage (P = 0.009) were independent risk factors for postoperative infectious complications. In particular, the incidence of pneumonia (P = 0.001) was significantly higher in the cholinesterase-low group. Age (P = 0.023), cerebrovascular comorbidities (P = 0.006), serum cholinesterase levels (P = 0.013), and total gastrectomy (P = 0.017) were identified as independent risk factors for postoperative pneumonia. CONCLUSIONS Preoperative serum cholinesterase levels were associated with postoperative pneumonia after gastrectomy for gastric cancer, suggesting the importance of preoperative nutritional assessment in gastric cancer surgery.

Abstract
PURPOSE Is to systematically review the available evidence of the patient's nutritional state before and after orthognathic surgery METHODS: The protocol to the International Prospective Register of Systematic Reviews (PROSPERO; registration No. CRD42020177156). RESULTS The search strategy yielded a total of 43 articles from all databases. Of the 43 articles, 13 were excluded after an examination of the titles and abstracts, and full-text articles of the remaining 30 studies were reviewed independently for eligibility. Of these 30 studies, 23 were excluded because they did not meet the inclusion criteria. Finally, a total of 7 studies met the inclusion criteria and were processed for critical review CONCLUSION: Patient's body weight and body mass index (BMI) decreases after orthognathic surgery. No significant changes in body fat percentage were observed. The estimated blood loss and the need for blood transfusion increased. No significant changes were observed in hemoglobin levels, lymphocyte counts, total cholesterol levels, and cholinesterase levels between the pre-operative and postoperative periods. Increments in serum albumin levels and total protein counts were observed after orthognathic surgery.

Abstract
BACKGROUND Atrial fibrillation (AF) is a very common arrhythmia with significant incidence rate and mortality. Several studies have shown a notable correlation between non-alcoholic fatty liver disease (NAFLD) and AF. It has been observed that serum cholinesterase (SChE) levels are elevated in individuals with fatty liver. However, the relationship between the SChE index and AF is still unclear. Therefore, the purpose of this study is to explore the association between the SChE index and the prevalence of AF in patients with hypertension. METHOD We collected cross-sectional data from January 2018 to April 2021 based on a retrospective study of cardiovascular disease. A total of 748 patients with hypertension were included, of whom 165 had AF. We used logistic regression models to test the relationship between SChE and the prevalence of AF in hypertensive patients. RESULT In hypertensive patients, the SChE index was significantly associated with AF (OR = 0.723, P < 0.001). After adjusting for potential confounding factors, this correlation was still significant (OR = 0.778, P < 0.001). The stability of the model was verified by adjusting the variable type of SChE. The data were further stratified according to whether the patient had fatty liver. In the stratified data, the correlation between SChE and atrial fibrillation was still significant (P < 0.05). CONCLUSION Our study showed that SChE was significantly negatively correlated with the occurrence of AF in patients with hypertension. And this correlation was not affected by whether the patient had fatty liver.

Abstract
Anorexia nervosa is associated with a significant risk of morbidity and mortality. In clinical practice, health risk is assessed and estimated using routinely collected laboratory data. This study will develop a risk score using clinically relevant laboratory parameters. The related question is how to estimate the health risk associated with underweight using body weight, height and age. METHODS We used routinely collected laboratory parameters from a total of 4087 patients. The risk score was calculated on the basis of electrolytes, blood count, transaminases and LDH. The nine parameters used were summed as zlog-transformed values. Where appropriate, the scales were inverted so that high values represented higher risk. For statistical prediction of the risk score, weight/height and age reference values from the WHO, the CDC (Center of Disease Control) and representative studies of German children and adults (KIGGS and NNS) were used. RESULTS The score calculated from nine laboratory parameters already shows a convincing relationship with BMI. Among the weight measures used for height and age, the z-score from the CDC reference population emerged as the best estimate, explaining 34% of the variance in health risk measured by the laboratory score. The percentile rank for each age-specific median weight from the KIGGS/NNS still explained more than 31% of the variance. In contrast, percentiles explained less variance than BMI without age correction. CONCLUSIONS The score we used from routine laboratory parameters appears to be an appropriate measure for assessing the health risk associated with underweight, as measured by the quality of the association with BMI. For estimating health risk based on weight, height and age alone, z-scores and percentages of age-specific median weight, as opposed to percentiles, are appropriate parameters. However, the study also shows that existing age-specific BMI reference values do not represent risk optimally. Improved statistical estimation methods would be desirable.

Abstract
PURPOSE Ectopic distal location of papilla of Vater (EDLPV) is an obvious pathological feature of choledochal cyst (CDC). This study aimed to investigate the correlation between EDLPV and clinical characteristics of CDCs. METHODS Three groups were studied: Group 1 (G1), papilla in the middle third of second part of duodenum (n = 38); Group 2 (G2), papilla from the distal third of second part to the beginning of third part of duodenum (n = 168); Group 3 (G3), papilla from the middle of third part to fourth part of duodenum (n = 121). Relative variables among three groups were compared. RESULTS Compared with G1 and G2, G3 patients had the largest cysts (relative diameter: 1.18 vs. 1.60 vs. 2.62, p < 0.001), the youngest age (20.52 vs. 19.47 vs. -3.40 months, p < 0.001), the highest rate of prenatal diagnosis (26.32% vs. 36.31% vs. 62.81%, p < 0.001), the lowest occurrence of protein plugs in common channel (44.74% vs. 38.69% vs. 16.53%, p < 0.001), and the most elevated total bilirubin level (7.35 vs. 9.95 vs. 28.70 μmol/L, p < 0.001). Prenatally diagnosed G3 patients had heavier liver fibrosis than G2 (13.16% vs. 1.67%, p = 0.015). CONCLUSION The more distal papilla location, the more severe clinical characteristics of CDCs, suggesting a crucial role in its pathogenesis.

Abstract
This study is the first systematic review to investigate the relationship between food insecurity (FI) and disordered eating behaviors exclusively in children and adolescents. Database searches were conducted in PUBMED, Embase, PsycINFO, ProQuest, and Gale OneFile: Informe Académico using English and Spanish search terms. Studies were included if they were published before August 2022, included youth aged 18 years and below, included either parent- or child-report of food security status, included either parent- or child-report of child disordered eating behaviors, and examined the relationship between food security status and child disordered eating behaviors. Following independent title/abstract and full-text screening, 20 studies were included in the review. There were 13 cross-sectional studies, five longitudinal studies, and two qualitative studies, from the United States (19 studies), and Bangladesh (1 study). Sample sizes ranged from 33 to 6077. Findings generally indicated a relationship between FI and behaviors such as binge eating, loss-of-control eating, eating in the absence of hunger, unhealthy weight control behaviors, and picky eating in children and adolescents, though this association varied depending on the type of disordered eating behavior assessed and FI severity. Results highlight the importance of screening for disordered eating behaviors among youth with FI towards eating disorder prevention and intervention. However, given the limited number of primary research articles examining this relationship in youth, further hypothesis-driven research is needed. In addition, more global representation and additional longitudinal studies are needed to further examine the generalizability and temporality of FI and disordered eating in children and adolescents.

Abstract
Objective Our aim was to assess the relationship between serum cholinesterase levels at intensive care unit admission and all-cause mortality in the pediatric intensive care unit. Methods We used the pediatric intensive care unit database (a large pediatric intensive care database in China from 2010 to 2018) to conduct a retrospective analysis to evaluate the serum cholinesterase levels at intensive care unit admission of 11,751 critically ill children enrolled to the intensive care unit. We analyzed the association between serum cholinesterase and all-cause mortality. Adjusted smoothing spline plots, subgroup analysis and segmented multivariate logistic regression analysis were conducted to estimate the relative risk between proportional risk between serum cholinesterase and death. Results Of the 11,751 children, 703 (5.98%) died in hospital. After adjusting for confounders, there was a negative association between serum cholinesterase and the risk of death in pediatric intensive care unit. For every 1,000 U/L increase in serum cholinesterase, the risk of death was reduced by 16% (adjusted OR = 0.84, 95% CI: 0.79, 0.89). The results of sensitivity analysis showed that in different stratified analyses (age, intensive care unit category, albumin, alanine aminotransferase, creatinine, neutrophils), the effect of serum cholinesterase on all-cause mortality remained stable. Conclusion After adjusting for inflammation, nutrition, and liver function factors, cholinesterase reduction is still an independent risk factor for pediatric intensive care unit all-cause mortality.

Liver and vitamin B 12 parameters in patients with anorexia nervosa before and after short-term weight restoration. Psychiatry Res 2022; 314:114673.

Abstract
Hepatic involvement in anorexia nervosa (AN) has been previously reported, but a link to elevated vitamin B12 concentrations, which can be a sign for liver damage, has not been thoroughly examined. We measured liver enzymes (alanine aminotransferase, aspartate aminotransferase, gamma-glutamyltransferase) and vitamin B12 parameters (total B12, holotranscobalamin, methylmalonic acid) in the plasma of young female patients with acute AN (n=77) and after short-term weight restoration (n=58, median body mass increase=25%), in comparison to healthy control participants (n=63). For a comprehensive assessment of vitamin B12 status, the combined marker cB12 was calculated. In acute AN, activities of alanine aminotransferase and gamma-glutamyltransferase as well as holotranscobalamin concentrations were elevated, and alanine aminotransferase activities positively correlated with total B12, holotranscobalamin and cB12 in patients with elevated liver enzyme activities. After weight restoration, alanine aminotransferase activities and holotranscobalamin concentrations were elevated, and cB12 increased above the level of the healthy control group. The present study provides further evidence for a hepatic involvement in acute AN in concert with vitamin B12 parameters and points to refeeding-associated alterations of liver and vitamin B12 parameters. Future studies should include non-invasive methods to characterize hepatic involvement and evaluate vitamin B12 status as a potential marker of liver damage/irritation.

Abstract
Anorexia nervosa (AN) is an eating disorder often accompanied by complicated medical conditions. It often results in increased serum levels of liver enzymes, especially transaminases, and affects both males and females. Here, we describe the cases of two patients admitted to our District General Hospital. The patients presented with malnourishment secondary to AN and severely deranged liver function tests. According to our literature review, patients who are malnourished are particularly susceptible to liver injury, and small insults can amount to exaggerated liver inflammation with transaminitis. Once other aetiologies are excluded, this can be interpreted as a benign clinical event and is not associated with adverse events or higher mortality.

Abstract
We report a simple 4 variables-based laboratory score taken on day +100 to predict transplant outcomes. The Day100 score stratifies patients into 3 groups for moderate-severe GVHD and TRM.
The aim of this study was to develop a predictive score for moderate-severe chronic graft-versus-host disease (cGVHD) on day +100 after allogeneic stem cell transplantation (HSCT). We studied 1292 patients allografted between 1990 and 2016, alive on day +100 after transplant, without cGVHD, and with full biochemistry laboratory values available. Patients were randomly assigned to a training and a validation cohort (ratio 1:1). In the training cohort, a multivariate analysis identified 4 independent predictors of moderate-severe cGVHD: gamma-glutamyl transferase ≥75 UI/l, creatinine ≥1 mg/dl, cholinesterase ≤4576 UI/l, and albumin ≤4 g/dl. A score of 1 was assigned to each variable, producing a low (0 to 1), intermediate (2 to 3), and high (4) score. The cumulative incidence of moderate-severe cGVHD was 12%, 20%, and 52% (P < .0001) in the training cohort, and 13%, 24%, and 33% (P = .002) in the validation cohort, respectively. The 5-year cumulative incidence of transplant-related mortality (TRM) was 5%, 14%, 27% (P < .0001) and 5%, 16%, 31% (P < .0001), respectively. The 5-year survival was 64%, 57%, 54% (P = .009) and 70%, 59%, 42% (P = .0008) in the 2 cohorts, respectively. In conclusion, Day100 score predicts cGVHD, TRM, and survival and, if validated in a separate group of patients, could be considered for trials of preemptive therapy.

Our study aims to evaluate if some indicators of disease severity, as body mass index (BMI), Phase Angle (PhA) and months of amenorrhea may be predictors of metabolic alterations (serum albumin, liver enzymes). METHODS In 154 outpatients with AN, case history was collected, and anthropometric and laboratory parameters measured. Patients were divided according to the following tertiles (T) of BMI, duration of amenorrhea and PhA: (1) BMI (T1 < 15.6; T2 15.6-16.8; T3 > 16.8 kg/m2); (2) Amenorrhea duration (T1 < 7; T2 7-14; T3 > 14 months); (3) PhA value (T1 < 4.64; T2 4.64-5.35; T3: > 5.35°). ROC curves were used to determine which of these three indicators (BMI, PhA and amenorrhea duration) might better identify patients belonging to Group A or B (less than 3 or more metabolic abnormalities). RESULTS The most frequent registered metabolic alterations were for alkaline phosphatase (ALP), alanine aminotransferase, cholesterol and hemoglobin. Aspartate aminotransferase, ALP and gamma glutamyl transferase abnormalities were frequent in the first tertiles of all the three indicators. Albumin was low in the T1 of BMI and PhA. No differences in nutritional alterations emerged according to amenorrhea duration. PhA had the best performance (AUCs: 0.721) in identifying patients with 3 or more abnormalities, with the optimal cut-off value of 4.5°. CONCLUSIONS Our data confirmed PhA as the more reliable predictor of metabolic alterations, followed by BMI and amenorrhea duration, especially in the first tertile. EVIDENCE-BASED MEDICINE Level 2.

Abstract
Anorexia nervosa (AN) is a life-threatening psychiatric disorder with not well-described pathogenesis. Besides the genetic and sociological factors, autoimmunity is also considered to take part in AN pathogenesis. We evaluated general serological factors showing the physiological state of 59 patients with AN at hospital admission and their discharge. We detected the altered levels of some general biochemical and immunological parameters. We also detected decreased levels of appetite-regulating alpha-melanocyte stimulating hormone (α-MSH) in patients at hospital admission. Moreover, elevated anti-α-MSH IgM levels and decreased anti-α-MSH IgA levels were observed in patients with AN. Therefore, we analyzed the gut microbiota composition with special focus on α-MSH antigen-mimetic containing microbes from the Enterobacteriaceae family. We correlated gut bacterial composition with anti-α-MSH Ig levels and detected decreasing IgG levels with increasing alpha diversity. The upregulation of pro-inflammatory cytokines IL-6, IL-17, and TNF-α were detected in patients with AN both prior and after hospitalization. We also evaluated the treatment outcome and improvement was observed in the majority of patients with AN. We provide new data about various serum biochemical parameters and their changes during the patients' hospitalization, with emphasis on the immune system, and its possible participation in AN pathogenesis.

Preoperative serum cholinesterase levels as a risk factor of postoperative complications for the elderly undergoing emergency surgery. Surg Today 2021; 51:1828-1834. [PMID: 33866402 DOI: 10.1007/s00595-021-02288-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Accepted: 02/28/2021] [Indexed: 10/21/2022]
Abstract
PURPOSES An accurate assessment of preoperative malnutrition in the elderly is critically important to predicting postoperative complications. The aim of this study is to evaluate the predictive value of the preoperative serum cholinesterase levels as a risk factor for postoperative complications in the elderly who have undergone emergency surgery. METHODS The study comprised 60 elderly patients who had undergone emergency major gastroenterological surgery. We retrospectively investigated the relationship between the preoperative serum cholinesterase levels and postoperative complications (Clavien-Dindo classification ≥ II). Univariate and multivariate analyses were performed to evaluate the risk factors for postoperative complications. RESULTS Thirty-three patients (55%) developed postoperative complications. According to the univariate analysis, hemoglobin (P = 0.018), albumin (P = 0.0036), cholinesterase (P < 0.001), C-reactive protein (P = 0.043), prognostic nutritional index (P = 0.0050), the Physiologic and Operative Severity Score for the enUmeration of Mortality and Morbidity (P < 0.001) and operation time (P = 0.042) were identified to be risk factors for postoperative complications. According to the multivariate analysis, low preoperative serum cholinesterase levels were found to be an independent risk factor for postoperative complications (P = 0.029). In the extremely elderly (80-95 years), the cholinesterase-low group had a higher complication rate compared to the cholinesterase-high group (77.8 vs 43.8%, P = 0.028). CONCLUSION The preoperative serum cholinesterase levels may be a risk factor for postoperative complications in elderly patients after emergency surgery, thus suggesting the significance of cholinesterase in evaluating the nutritional status.

Abstract
BACKGROUND College students experience a disproportionately high prevalence of both food insecurity and eating disorders. Food insecurity is associated with stress, irregular eating patterns, weight change, depression, and body dissatisfaction, making it a possible risk factor for the onset of eating disorders. However, the association between food insecurity and eating disorders among college students is not well understood. OBJECTIVE This study explored the relation between food insecurity and screening positive for an eating disorder among students attending a large, public Midwestern university. DESIGN Cross-sectional data were collected using an online survey administered from March through June 2018. PARTICIPANTS/SETTING Participants were recruited from a random sample of 2,000 students, with oversampling from the following groups: racial/ethnic minorities, first-generation students, and students from lower-income households. Of those sampled, 851 students (43%) responded. The final analytic sample comprised 804 students after excluding those with missing data. MAIN OUTCOME MEASURE The validated 5-item Sick, Control, One stone, Fat, Food (SCOFF) questionnaire was used to screen for the presence of an eating disorder. STATISTICAL ANALYSES PERFORMED Poisson regression was used to model prevalence ratios for positive SCOFF screens (≥2 affirmative responses) by levels of food security (ie, high, marginal, low, or very low). Models were adjusted for sex, age, race/ethnicity, degree type, financial aid, and first-generation student status. RESULTS Compared to students with high food security, a higher prevalence of positive SCOFF screens was found among students with marginal food security (prevalence ratio [PR], 1.83, 95% CI 1.26 to 2.65; P = 0.001), low food security (PR 1.72, 95% CI 1.16 to 2.54; P = 0.007), and very low food security (PR 2.83, 95% CI 2.01 to 3.97; P < .0001). CONCLUSIONS Students with food insecurity at any level were more likely to screen positive for an eating disorder via the SCOFF questionnaire. Prospective studies are needed to determine whether food insecurity is a risk factor for the onset of eating disorders among college students.

Abstract
PURPOSE The purpose of this study was to evaluate patients' nutritional state after orthognathic surgery. METHODS The subjects were 40 female patients with dentofacial deformity aged 17-33 years who were undergoing bilateral sagittal splitting ramus osteotomy. Twenty patients were treated with intermaxillary fixation, and 20 patients were treated without intermaxillary fixation. Age and body mass index (kg/m2) were assessed as physical factors, operation time, blood loss, and amount of mandibular movement with or without intermaxillary fixation were assessed as operation stress factors, and the following laboratory data, total protein, serum albumin, total cholesterol, total lymphocytes, and cholinesterase were assessed as nutritional state factors at 1 and 2 weeks after surgery. Statistical analysis was performed for body weight loss and relationship between body weight loss and examination factors. RESULTS Body weight significantly decreased 2.3% at 1 week and 3.9% at 2 weeks after surgery rather than preoperation. All laboratory data except total lymphocyte were decreased at 1 week after surgery and still remained significantly decreased at 2 weeks after surgery. There was a statistically significant relationship between body weight loss at 1 week after surgery and operation time. CONCLUSIONS These results indicate that long operation time caused body weight loss in orthognathic surgery.

Abstract
BACKGROUND Patients undergoing subtotal esophagectomy for esophageal cancer frequently experience postoperative pneumonia. Development of preoperatively determined predictors for postoperative pneumonia will facilitate identifying high-risk patients and will assist with informing patients about their risk of postoperative pneumonia, enabling physicians to estimate with greater accuracy, will result in tailoring perioperative management. METHODS Postoperative pneumonia was defined according to the revised Uniform Pneumonia Score. We analyzed the data for 355 patients to compare 32 potential predictive variables associated with postoperative pneumonia after subtotal esophagectomy. RESULTS Forty-one patients (11.5%) had postoperative pneumonia. Preoperative cholinesterase (ChE) concentrations demonstrated the greatest area under the curve value (0.662) to predict postoperative pneumonia (optimal cutoff value = 217 IU/l). Univariate analysis identified a continuous value of preoperative ChE concentration as a significant risk factor for postoperative pneumonia (P = 0.0014). Multivariable analysis using factors potentially relevant to pneumonia revealed that preoperative ChE concentration was one of independent risk factors for pneumonia after esophagectomy (P = 0.008). Patients with low ChE concentrations were at increased risk of postoperative pneumonia in most patient subgroups. Moreover, the odds ratios of low ChE concentrations were highest in patients undergoing neoadjuvant treatment. A combination of preoperative serum ChE concentrations and Brinkman index stratified patients into low, intermediate, and high risk of postoperative pneumonia. CONCLUSIONS Our findings indicate that preoperative ChE concentrations, particularly in combination with Brinkman index, may serve simply as a determined predictor of pneumonia after subtotal esophagectomy and may facilitate physicians' efforts to reduce the incidence of postoperative pneumonia.

Abstract
PURPOSE The aim of this study was to evaluate an association between nutritional biomarkers and prognosis in septic patients. METHODS We retrospectively searched the association between nutritional biomarkers including serum albumin (Alb), total protein (TP), total cholesterol (T-chol), and cholinesterase (ChE), and prognosis for septic patients treated in the ICU for >7 days. We used time-dependent Cox proportional hazard regression analysis to resolve the difference of the statistical weight of each day's data for all 14 consecutive days among individual sepsis patients. The covariates were based on the minimum moving values determined from 1 day, 3 days, 7 days, and 14 days of serial data. The values of these covariates and ICU survival were considered as outcomes. RESULTS We included 136 septic patients. The decreases in the values of Alb, TP, T-chol, and ChE were significantly associated with the risk of death in the septic patients (p < .05). Especially, the daily changes of Alb were significantly associated with mortality during the ICU stay (p < .05). CONCLUSIONS We found that the changes in serial data of the nutritional markers of Alb, TP, T-chol, and ChE reflected the higher risk of death in patients with prolonged sepsis.

Abstract
Objective An experiment was conducted to investigate the effects of feed intake restriction during late pregnancy on the function, anti-oxidation capability and acute phase protein synthesis of ovine liver. Methods Eighteen time-mated ewes with singleton fetuses were allocated to three groups: restricted group 1 (RG1, 0.18 MJ ME/kg W0.75 d, n = 6), restricted group 2 (RG2, 0.33 MJ ME/kg W0.75 d), n = 6) and a control group (CG, ad libitum, 0.67 MJ ME/kg W0.75 d, n = 6). The feed restriction period was from 90 days to 140 days of pregnancy. Results The ewe’s body weight, liver weights, water, and protein content of liver in the restricted groups were reduced compared with the CG group (p<0.05), but the liver fat contents in the RG1 group were higher than those of the CG group (p<0.05). The increased hepatic collagen fibers and reticular fibers were observed in the restricted groups with the reduction of energy intake. The concentrations of nonesterified free fatty acids in the RG1 and RG2 groups were higher than those of the CG group with the reduction of energy intake (p<0.05), but there were decreased concentrations of lipoprotein lipase and hepatic lipase in both restricted groups compared with the CG group (p<0.05). In addition, the increased concentrations of β-hydroxybutyric acid, triglycerides, malondialdehyde, total antioxidant capacity and activities of superoxide dismutase activity and catalase were found in the RG1 group, and the concentrations of cholinesterase in the RG1 group were reduced compared with the CG group (p<0.05). For the concentrations of acute phase proteins, the C-reactive protein (CRP) in the RG1 group were reduced compared with the CG group, but there were no differences in haptoglobin relative to the controls (p>0.05). Conclusion The fat accumulation, increased hepatic fibrosis, antioxidant imbalance and modified synthesis of acute phase proteins were induced in ewe’s liver by maternal malnutrition during late pregnancy, which were detrimental for liver function to accommodate pregnancy.

Abstract
Anorexia nervosa (AN) is a psychiatric disease with devastating physical consequences, with a pathophysiological mechanism still to be elucidated. Metagenomic studies on anorexia nervosa have revealed profound gut microbiome perturbations as a possible environmental factor involved in the disease. In this study we performed a comprehensive analysis integrating data on gut microbiota with clinical, anthropometric and psychological traits to gain new insight in the pathophysiology of AN. Fifteen AN women were compared with fifteen age-, sex- and ethnicity-matched healthy controls. AN diet was characterized by a significant lower energy intake, but macronutrient analysis highlighted a restriction only in fats and carbohydrates consumption. Next generation sequencing showed that AN intestinal microbiota was significantly affected at every taxonomic level, showing a significant increase of Enterobacteriaceae, and of the archeon Methanobrevibacter smithii compared with healthy controls. On the contrary, the genera Roseburia, Ruminococcus and Clostridium, were depleted, in line with the observed reduction in AN of total short chain fatty acids, butyrate, and propionate. Butyrate concentrations inversely correlated with anxiety levels, whereas propionate directly correlated with insulin levels and with the relative abundance of Roseburia inulinivorans, a known propionate producer. BMI represented the best predictive value for gut dysbiosis and metabolic alterations, showing a negative correlation with Bacteroides uniformis (microbiota), with alanine aminotransferase (liver function), and with psychopathological scores (obsession-compulsion, anxiety, and depression), and a positive correlation with white blood cells count. In conclusion, our findings corroborate the hypothesis that the gut dysbiosis could take part in the AN neurobiology, in particular in sustaining the persistence of alterations that eventually result in relapses after renourishment and psychological therapy, but causality still needs to be proven.

Abstract
INTRODUCTION Butyrylcholinesterase (BChE) is involved in the metabolism of endogenous lipids and xenobiotics, such as esters of carboxylic or phosphoric acids. Butyrylcholinesterase activity is associated with both inflammation and oxidative stress. Changes in the activity of this enzyme have been observed in various diseases such as liver cirrhosis, diabetes, neurodegenerative disease and others. MATERIAL AND METHODS The study involved 30 patients with chronic obstructive pulmonary disease (COPD) and 18 healthy subjects. The COPD patients were divided according to the severity of the disease by applying the classification of COPD based on GOLD standards for forced expiratory volume in 1 s (FEV1) and the FEV1/forced expiratory volume (FVC) ratio. The control group comprised blood samples collected from healthy subjects without concomitant diseases related to the respiratory system. Butyrylcholinesterase activity, lipid peroxidation and total antioxidant capacity (TAC) were determined in the blood plasma. RESULTS A significant (p < 0.05) decrease in the activity of BChE, associated with an increase in lipid peroxidation and a decrease in the total antioxidant capacity, was observed in blood plasma of patients with chronic obstructive pulmonary disease. CONCLUSIONS The study shows for the first time that activity of BChE in the blood plasma of patients diagnosed with chronic obstructive pulmonary disease is considerably reduced compared with healthy subjects. These changes were accompanied by a decrease of TAC and an increase of lipid peroxidation, which suggests that they may be related to the oxidative stress induced by COPD disease.

Abstract
OBJECTIVE Anorexia nervosa (AN) is a complex disorder involving severe psychological manifestations and multiple organ damage, including liver dysfunction. The primary aim of this study consisted in assessing plasma levels of vitamin B12 and folates with respect to liver function enzymes considering the liver-storage properties of this vitamin. METHOD We recruited 70 restrictive type AN adolescents and the severity of psychopathological traits was assessed using EDI-3 scale. Plasma levels of vitamin B12 , folates, transaminases (AST, ALT), gamma-glutamyl transpeptidase (GGT), alkaline phosphatase (ALP) and cholinesterase (CHE) were determined. RESULTS About 38.5% of patients displayed vitamin B12 values (H-B12) above the upper range of normal reference; 4.3% of patients had increased values of folates; 20 and 11.4% of patients displayed ALT and AST values above reference limits; none had GGT values above normal range. Albeit low CHE and ALP values were found in 55 and 20% of patients, respectively, a linear correlation with both transaminases was present only for vitamin B12 and folates; furthermore, H-B12 patients had both higher AST and ALT values. EDI- 3 subscores significantly correlated with vitamin B12 and folates plasma values and H-B12 patients displayed EDI-3 higher values. DISCUSSION These data suggest that plasma levels of vitamin B12 might be an early marker of liver dysfunction, possibly also related to more severe psychopathological aspects. The identification of patients with higher fasting plasma vitamin B12 levels could therefore lead to earlier and more careful refeeding interventions. Further studies will clarify the potential role of this vitamin in AN clinical practice.

Abstract
Autophagy, a lysosomal catabolic pathway for long-lived proteins and damaged organelles, is crucial for cell homeostasis, and survival under stressful conditions. During starvation, autophagy is induced in numerous organisms ranging from yeast to mammals, and promotes survival by supplying nutrients and energy. In the early neonatal period, when transplacental nutrients supply is interrupted, starvation-induced autophagy is crucial for neonates' survival. In adult animals, autophagy provides amino acids and participates in glucose metabolism following starvation. In patients with anorexia nervosa, autophagy appears initially protective, allowing cells to copes with nutrient deprivation. However, when starvation is critically prolonged and when body mass index reaches 13 kg/m(2) or lower, acute liver insufficiency occurs with features of autophagic cell death, which can be observed by electron microscopy analysis of liver biopsy samples. In acetaminophen overdose, a classic cause of severe liver injury, autophagy is induced as a protective mechanism. Pharmacological enhancement of autophagy protects against acetaminophen-induced necrosis. Autophagy is also activated as a rescue mechanism in response to Efavirenz-induced mitochondrial dysfunction. However, Efavirenz overdose blocks autophagy leading to liver cell death. In conclusion, in acute liver injury, autophagy appears as a protective mechanism that can be however blocked or overwhelmed.

Abstract
Elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels are frequently reported in patients with anorexia nervosa (AN) and in subjects who are overweight or with hyperlipidemia, which can be found to be associated with binge eating disorder (BED) and bulimia nervosa (BN). Liver functioning and psychopathological features have been evaluated in 43 patients with AN, 33 with BN, and 32 with BED. Body mass index was found to be inversely associated with AST and ALT in AN, and directly associated with AST and ALT in BED. A positive association between ALT and AST and body shape concern in AN was observed. Liver enzymes could be considered as an index of severity in AN and BED patients.

Abstract
This study investigated the effects of maternal undernutrition during late pregnancy on the development and function of ovine fetal liver. Eighteen ewes with singleton fetuses were allocated to three groups at d 90 of pregnancy: Restricted Group 1 (RG1, 0.175MJMEkgBW(-0.75)d(-1), n=6), Restricted Group 2 (RG2, 0.33MJMEkgBW(-0.75)d(-1), n=6) and a Control Group (CG, ad libitum, 0.67MJMEkgBW(-0.75)d(-1), n=6). Fetuses were recovered at slaughter on d 140. Fetuses in the RG1 group exhibited decreased (P<0.05) liver weight, total antioxidant capacity (T-AOC), superoxide dismutase activity (SOD), cholinesterase (CHE), total protein (TP), globulin (GLB), and alanine transaminase (ALT). In addition, intermediate changes were found in the RG2 fetuses, including decreased liver weight, T-AOC and CHE (P<0.05). In contrast, increases in fetal hepatic collagen fibers and reticular fibers, glutathione peroxidase (GSH-Px), malondialdehyde (MDA), nitric oxide (NO), nitric oxide synthase (NOs), monoamine oxidase (MAO), albumin (ALB)/GLB, aspartate transaminase (AST), and AST/ALT were found in the RG1 fetuses (P<0.05). The RG2 fetuses had increased fetal hepatic collagen fibers, NOs and MAO (P<0.05) relative to the control fetuses. These results indicate that impaired fetal hepatic growth, fibrosis, antioxidant imbalance and dysfunction were associated with maternal undernutrition.

Abstract
BACKGROUND Butyrylcholinesterase (BChE) is an α-glycoprotein synthesized in the liver. Its serum level decreases in many clinical conditions such as acute and chronic liver damage, inflammation, injury and infections, and malnutrition. METHODS AND RESULTS This review collects the main evidence on the emerging role of butyrylcholinesterase as a prognostic marker of liver and nonliver diseases as well as a marker of protein-energy malnutrition and obesity. In fact, serum concentrations and BChE activity seem to accurately reflect the availability of amino acidic substrates and/or derangement in protein synthesis due to hepatocellular damage. In cancer, with or without liver impairment, serum BChE levels serve as an accurate functional and prognostic indicator, useful for monitoring clinical and therapeutic interventions according to patients' prognosis. In the absence of inflammation, BChE could also serve as an index of the effectiveness of nutritional support. CONCLUSIONS Serum BChE assessment should be included in routine clinical diagnostic procedures to evaluate patient clinical conditions, in particular in cases of inflammation and/or protein-energy malnutrition.

Abstract
In anorexia nervosa, under-nutrition and weight regulatory behaviours such as vomiting and laxative abuse can lead to a range of biochemical problems. Hypokalaemia is the most common electrolyte abnormality. Metabolic alkalosis occurs in patients who vomit or abuse diuretics and acidosis in those misusing laxatives. Hyponatraemia is often due to excessive water ingestion, but may also occur in chronic energy deprivation or diuretic misuse. Urea and creatinine are generally low and normal concentrations may mask dehydration or renal dysfunction. Abnormalities of liver enzymes are predominantly characterized by elevation of aminotransferases, which may occur before or during refeeding. The serum albumin is usually normal, even in severely malnourished patients. Amenorrhoea is due to hypogonadotrophic hypogonadism. Reduced concentrations of free T4 and free T3 are frequently reported and T4 is preferentially converted to reverse T3. Cortisol is elevated but the response to adrenocorticotrophic hormone is normal. Hypoglycaemia is common. Hypercholesterolaemia is a common finding but its significance for cardiovascular risk is uncertain. A number of micronutrient deficiencies can occur. Other abnormalities include hyperamylasaemia, hypercarotenaemia and elevated creatine kinase. There is an increased prevalence of eating disorders in type 1 diabetes and the intentional omission of insulin is associated with impaired metabolic control. Refeeding may produce electrolyte abnormalities, hyper- and hypoglycaemia, acute thiamin depletion and fluid balance disturbance; careful biochemical monitoring and thiamin replacement are therefore essential during refeeding. Future research should address the management of electrolyte problems, the role of leptin and micronutrients, and the possible use of biochemical markers in risk stratification.

Abstract
OBJECTIVES To determine the presence or extent of arginine deficiency in pressure ulcer (PU) patients on percutaneous endoscopic gastrostomy (PEG) feeding and to examine the effects of arginine supplementation on PU healing. DESIGN All eligible PEG patients, with and without PU, were cross-sectionally assessed for plasma arginine. Three-month supplementation with arginine-enriched water (Arginaid Water) was performed on a subset of patients with PU. This intervention study was a prospective, non-controlled trial with 5 PU patients. SETTING Geriatric ward of a rural clinical hospital in Japan. PARTICIPANTS Thirty-nine inpatients with PEG feeding were assessed for plasma arginine. Five of the 13 patients with PU and five of 26 patients without PU underwent amino acid profiling. INTERVENTION Five of the patients with PU received Arginaid Water supplementation. MEASUREMENTS Plasma amino acid measurements and biochemical analyses were performed. For those with PU on Arginaid Water supplementation, plasma arginine concentration and PU status were monitored every month. RESULTS Patients with PU showed significantly lower plasma arginine concentration compared to those without PU (control vs. PU; 80.2±21.3 vs 62.8±14.7 nmol/ml, p<0.01). After the addition of Arginaid Water, plasma arginine concentration increased (before vs 3 months later; 57.9±1.8 vs 83.1±8.5, p<0.01), and PU area, perimeter, DESIGN-R and PUSH scores significantly improved. CONCLUSION Plasma arginine was lower in PEG patients with PU. The healing rate of PU is improved with Arginaid Water supplementation. The findings from this study support the use of arginine supplementation in PEG patients with PU.

Abstract
Anorexia nervosa (AN) has serious negative effects on multiple organs and systems of the human body. As patients often do not make their eating disorder the subject of discussion, the physician is forced to rely on the physical examination and laboratory parameters as diagnostic hints. Obvious signs of AN are a body mass index (BMI) below 17.5 kg/m, dry and scaly skin, lanugo, edema, acrocyanosis, petechias, dental problems, and low blood pressure. However, because the often complex laboratory alterations can be difficult for the general psychiatrist to interpret, this article presents some useful guidelines. The plasma of patients with AN often shows alterations in laboratory parameters and appetite regulators, including electrolytes, liver enzymes, leukocyte count, hemoglobin (Hb), leptin, neuropeptide Y (NPY), triiodothyronine (T3), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen, ghrelin, pancreatic polypeptide (PP), tumor necrosis factor-alpha (TNF-alpha), and cortisol. Medical problems secondary to AN or due to the treatment itself may lead to further laboratory abnormalities. To date, despite these associated laboratory alterations, the diagnosis of anorexia is a clinical one, based on weight and specific psychopathology.

Abstract
Background The liver function test (LFT) is among the most commonly used clinical investigations to assess hepatic function, severity of liver diseases and the effect of therapies, as well as to detect drug-induced liver injury (DILI). Aims To determine the relative contribution of genetic and environmental factors as well as test and quantify the effects of sex, age, BMI and alcohol consumption to variation in liver function test proteins - including alanine amino transaminase (ALT), Albumin, gamma glutamyl transpeptidase (GGT), total bilirubin, total protein, total globulin, aspartate transaminase (AST), and alkaline phosphotase (ALP) - using the classical twin model. Methods Blood samples were collected from a total of 5380 twin pairs from the TwinsUK registry. We measured the expression levels of major proteins associated with the LFT, calculated BMI from measured weight and height and questionnaires were completed for alcohol consumption by the twins. The relative contribution of genetic and environmental factors to variation in the LFT proteins was assessed and quantified using a variance components model fitting approach. Results Our results show that (1) variation in all the LFTs has a significant heritable basis (h2 ranging from 20% to 77%); (2) other than GGT, the LFTs are all affected to some extent by common environmental factors (c2 ranging from 24% to 54%); and (3) a small but significant proportion of the variation in the LFTs was due to confounding effects of age, sex, BMI, and alcohol use. Conclusions Variation in the LFT proteins is under significant genetic and common environmental control although sex, alcohol use, age and BMI also contribute significantly to inter-individual variation in the LFT proteins. Understanding the underlying genetic contribution of liver function tests may help the interpretation of their results and explain wide variation among individuals.
