Effects of perinatal protein restriction on the oxidative balance in the hypothalamus of 60-day-old rats / Efeitos da restrição proteica perinatal sobre o balanço oxidativo no hipotálamo de ratos de 60 dias de idade

ABSTRACT Objective Evaluate the effects of maternal low-protein diet on the oxidative stress in the hypothalamus of 60-day-old rats. Methods Male Wistar rats were divided into two experimental groups according to the mother's diet during pregnancy and lactation; control group (NP:17% casein n=6) and a malnourished group (LP:8% casein n=6). At 60 days of life, the rats were sacrificed for the collection of the hypothalamus for further biochemical analysis. Results Our results showed an increase in oxidative stress in malnourished group, observed through an increase in carbonyl content (p=0.0357), a reduction in the activity of the glutathione-S-transferase enzyme (p=0.0257), and a reduction in the non-enzymatic antioxidant capacity evidenced by the decrease in the ratio reduced glutathione/oxidized glutathione (p=0.0406) and total thiol levels (p=0.0166). Conclusion A low-protein diet during pregnancy and lactation is closely associated with increased oxidative stress and reduced antioxidant capacity in the hypothalamus of sixty-day-old rats.

RESUMO Objetivo Avaliar os efeitos da restrição proteica materna sobre o estresse oxidativo no hipotálamo de ratos de 60 dias de idade. Métodos Ratos Wistar machos foram divididos em dois grupos experimentais de acordo com a dieta da mãe durante a gestação e lactação: grupo controle (NP: 17% caseína n=6) e grupo desnutrido (LP: 8% caseína n=6). Aos 60 dias de vida, os ratos foram sacrificados para coleta do hipotálamo para posterior análise bioquímica. Resultados Os resultados demonstraram aumento do estresse oxidativo no grupo desnutrido, observado através do aumento do conteúdo de cabonilas (p=0,0357) e redução da atividade da enzima glutationa-S-transferase (p=0,0257) e da capacidade antioxidante não enzimática, evidenciada pela queda da razão glutationa reduzida/glutationa oxidada (p=0,0406) e dos níveis de tióis totais (p=0,0166). Conclusão Uma dieta com baixo teor de proteínas durante a gestação e lactação está intimamente associada ao aumento do estresse oxidativo e à redução da capacidade antioxidante no hipotálamo de ratos de 60 dias de vida.

Influence of protein energy wasting on frailty in elderly patients on maintenance hemodialysis / 中华老年医学杂志

Objective:To explore the correlation between protein energy wasting(PEW)and frailty in elderly patients on maintenance hemodialysis(MHD)and influencing factors of frailty.Methods:Clinical data of patients over 60 who had received regular hemodialysis treatment at Beijing Huairou Hospital between September to December 2021 were collected.According to Fried's evaluation criteria, patients were divided into a frailty group and a non-frailty group, and differences between the two groups were compared.Spearman correlation analysis was conducted to assess the correlation between protein energy wasting and frailty.Logistic regression was used to analyze the influencing factors of frailty in elderly patients on MHD.Results:A total of 81 MHD patients enrolled in this study, with 36 in the frailty group.The frailty group was older, had a higher proportion of patients with PEW, and underwent more months of dialysis, with a higher proportion of patients with diabetic nephropathy as the primary disease, having high levels of C-reactive protein(CRP), and having low KT/V, hemoglobin, albumin, body mass index(BMI), mid-arm circumference(MAC)and mid-arm muscle circumference(MAMC), and the differences with the control group were statistically significant(all P<0.05). The Fried frailty phenotype was positively correlated with age( r=0.021, P=0.047), but negatively associated with HGB( r=-0.329, P=0.003), albumin( r=0.021, P=0.047), BMI( r=0.021, P=0.047), TSF( r=-0.274, P=0.013), MAC( r=-0.554, P<0.001)and MAMC( r=-0.293, P=0.008). A Logistic regression equation was constructed using frailty as the dependent variable.The results showed that age, months of dialysis, KT/V, serum albumin and CRP were independent factors influencing the development of frailty in elderly patients with MHD. Conclusions:PEW and frailty coexist and interact with each other in elderly patients with MHD.Clinicians should place emphasis on the assessment of frailty and protein energy wasting in elderly dialysis patients and achieve early detection and intervention to avoid adverse clinical outcomes.

Traditional Chinese Medicine Syndromes and Influencing Factors of Protein Energy Wasting in Chronic Kidney Disease Patients Undergoing Maintenance Hemodialysis：a Cross-sectional Study / 中医杂志

ObjectiveTo investigate the distribution of traditional Chinese medicine （TCM） syndrome types and influencing factors of protein-energy wasting （PEW） in chronic kidney disease （CKD） undergoing maintenance hemodialysis （MHD）. MethodsAccording to diagnostic criteria， 164 patients with MHD were divided into PEW group and non-PEW group. The clinical data of all patients were collected， including general information such as gender， age， height and weight， disease characteristics such as course， cormobidity， and haemodialysis duration， laboratory indicators such as blood routine， liver function， renal function， electrolyte， blood lipid， grip strength， and the four examinations. Logistic regression analysis was used to find the influencing factors of PEW by taking the clinical indicators with significant differences between the two groups （P＜0.05） as the independent variables， diagnosis of PEW as the dependent variable， and normal values as the reference. ResultsOut of 164 patients with MHD， there were 96 （58.5%） cases in PEW group and 68 cases （41.5%） in non-PEW group. Compared to the non-PEW group，PEW group had increased age， ratios of bedrest， deep vein preservation， edema， and low grip strength， percentages of comorbidities type 2 diabetes， cardiovascular and cerebrovascular diseases，infections and anemia， and levels of alanine aminotransferase and permine amin aminotransferase， as well as decreased body mass index， self-care ratio，internal arteriovenous fistula， red blood cell count， hemoglobin， serum total protein， serum albumin levels （P＜0.05）. The PEW group had significantly higher frequency of poor appetite and digestion， abdominal distension， fear of cold and preference of warmth， weak breathing and fatigue， poor appetite， oliguria， nausea and vomiting than non-PEW group （P＜0.05）. The incidence of both yin and yang deficiency syndrome and damp-turbidity syndrome were significantly higher in the PEW group than the non-PEW group， while that of liver-kidney yin deficiency syndrome and stirring of wind syndrome were lower （P＜0.05）. Logistic regression analysis showed that low BMI （＜22 kg/m2）， inability to take care of oneself， low grip strength，low serum albumin （＜38 g/L）， infection， older age， fear of cold and cold limbs，and poor appetite were the risk factors of PEW in patients undergoing MHD （P＜0.05）. ConclusionThe root syndrome of MHD-PEW patients is both yin and yang deficiency， concurrent with damp-turbidity syndrome. Low BMI， low serum albumin， infection and older age may be the influencing factors of PEW in patients undergoing MHD.

Clinical evaluation of malnutrition in maintenance hemodialysis patients / 国际生物医学工程杂志

Objective:To study the evaluation method of protein energy wasting (PEW) in maintenance hemodialysis patients.Methods:A total of 166 maintenance hemodialysis patients were selected. Their medical records, physical indicators, as well as NS2002, PG-SGA, and MUST nutrition scale scores were also collected. The patients were divided into PEW and non-PEW groups according to whether PEW occurred or not, and the differences in each index between the two groups were compared to analyze the diagnostic efficacy of each index and nutrition score scale results on the occurrence of PEW.Results:The differences in body mass, body mass index(BMI), body surface area, abdominal circumference, triceps skinfold thickness, upper arm circumference, and calf circumference between the PEW and non-PEW groups were statistically significant(all P<0.05). The diagnostic efficacy of a single physical index or nutrition score for PEW was limited. A simplified formula for the PEW risk was obtained by logistic model analysis. The formula had a sensitivity of 67.7% and a specificity of 94.4% for the diagnosis of PEW, as analyzed by the subject's working characteristic curve. Conclusions:Four indicators, including abdominal circumference, primary hand grip strength, BMI, and upper arm circumference, can be combined to comprehensively assess the presence of PEW to improve the diagnostic efficacy of the occurrence of malnutrition in maintenance hemodialysis patients.

Effect of Modified Shenling Baizhusan on Gastrointestinal Dysfunction and Protein-energy Wasting in Continuous Ambulatory Peritoneal Dialysis Patients / 中国实验方剂学杂志

ObjectiveTo observe and analyze the effect of modified Shenling Baizhusan on gastrointestinal dysfunction and protein-energy wasting （PEW） of continuous ambulatory peritoneal dialysis （CAPD） patients with the syndrome of spleen deficiency， blood stasis， and dampness. MethodA total of 66 CAPD patients with the above syndrome were randomized into the observation group and control group， 33 cases in each group. However， 3 cases in each group dropped out， finally leaving 30 cases in each group. Both groups received CAPD and conventional symptomatic treatment. On this basis， the observation group was given modified Shenling Baizhusan （1 bag/day， once in the morning and again in the evening， 12 weeks）， and the control group the bifidobacterium capsules （1.05 g/time， twice/day， 12 weeks）. Before and after treatment， the traditional Chinese medicine （TCM） syndrome score， gastrointestinal symptom rating scale （GSRS） score， and malnutrition-inflammation score （MIS） in two groups were recorded， and the levels of serum albumin （ALB）， prealbumin （PA）， transferrin （TRF）， gastrin-17 （G-17）， tumor necrosis factor alpha （TNF-α）， interferon-γ （IFN-γ）， and interleukin-10 （IL-10） were detected. Moreover， body mass index （BMI） was calculated. ResultAfter treatment， the alleviation of the TCM syndrome in the observation group was better than that in the control group （Z=-2.591， P<0.05）， and the TCM syndrome score in the observation group was lower than that in the control （P<0.05）. The symptom scores， MIS， and G-17 of the observation group were significantly decreased compared with those before observation and in the control group （P<0.05）. After treatment， the GSRS scores of the two groups were significantly lower than those before treatment （P<0.05）， particularly the observation group （P<0.05）. ALB， PA， TRF， and BMI of the observation group after treatment were increased compared with those before treatment and those of the control group after treatment （P<0.05）. After treatment， serum TNF-α and IFN-γ of the two groups were significantly reduced compared with those before treatment （P<0.05）， and the levels of the two in the observation group were significantly lower in the observation group than in the control group （P<0.05）. After treatment， IL-10 level of the observation group was higher than that before treatment and in the control group （P<0.05）. ConclusionThe modified Shenling Baizhusan can relieve the gastrointestinal dysfunction and PEW in CAPD patients with the syndrome of spleen deficiency， blood stasis， and dampness.

Clinical features of frailty syndrome and its association with all-cause mortality in elderly patients undergoing maintenance hemodialysis / 中华肾脏病杂志

Objective:To investigate the clinical characteristics and risk factors of frailty syndrome in elderly patients undergoing maintenance hemodialysis (MHD) and the effect of frailty syndrome on all-cause mortality.Methods:This was a prospective cohort study. MHD patients aged≥60 years in 5 hemodialysis centers in Beijing from April to June 2017 were selected as the study subjects. Baseline data were collected and compared, and the patients were then classified into non-frailty, pre-frailty and frailty syndrome groups according to the Fried criteria and followed up until June 2018. The end point event was all-cause death. Multivariate logistic regression was used to analyze the independent risk factors of frailty syndrome. Kaplan-Meier survival analysis was used to compare the difference in the cumulative survival rate among the 3 groups. A multivariate Cox regression model was used to analyze the independent risk factors of all-cause mortality.Results:A total of 204 patients aged (71.65±5.89) years (60-81 years) were enrolled into this study, including 123 males (60.29%), 147 patients (72.06%) in the frailty syndrome group, 41 patients (20.10%) in the pre-frailty group, and 16 patients (7.84%) in the non-frailty group. Patients with frailty syndrome tended to be older, longer dialysis vintage, a higher proportion of diabetes, lower urea clearance index (Kt/V) and lower serum albumin level (all P<0.05). Multivariate Logistic regression showed that factors independently associated with frailty syndrome included age ( OR=1.393, 95% CI 1.241-1.563, P<0.001), history of diabetes ( OR=3.610, 95% CI 1.262-10.327, P=0.017), dialysis vintage ( OR=1.011, 95% CI 1.002-1.020, P=0.019), Kt/V ( OR=0.711, 95% CI 0.516-0.979, P=0.037), serum albumin ( OR=0.754, 95% CI 0.644-0.882, P<0.001) and intact parathyroid hormone (iPTH, OR=1.344, 95% CI 1.024-1.763, P=0.033). Kaplan-Meier survival analysis showed that the cumulative survival rate in frailty syndrome group was significantly lower than those of pre-frailty (Log-rank χ2=7.265, P=0.007) and non-frailty groups (Log-rank χ2=5.238, P=0.022). Multivariate Cox regression analysis indicated that frailty syndrome ( HR=3.832, 95% CI 1.116-13.157, P=0.033), age ( HR=1.074, 95% CI 1.014-1.136, P=0.014), history of diabetes ( HR=2.009, 95% CI 1.067-3.784, P=0.031), cognitive impairment (Montreal cognitive assessment<26, HR=2.627, 95% CI 1.142-6.042, P=0.023), Kt/V ( HR=0.701, 95% CI 0.545-0.902, P=0.006), serum albumin ( HR=0.891, 95% CI 0.806-0.986, P=0.025) and iPTH ( HR=1.226, 95% CI 1.100-1.367, P<0.001) were independently associated with all-cause mortality. Conclusions:The prevalence of frailty syndrome in elderly patients undergoing hemodialysis is high. Ageing, diabetes history, long dialysis vintage, low levels of Kt/V and serum albumin, and elevated iPTH level are independent risk factors for frailty syndrome in such patients. Frailty syndrome is independently associated with an increased risk of all-cause mortality.

Effect of low-dose esketamine on postoperative delirium in elderly frail patients undergoing laparoscopic radical resection of gastrointestinal tumor / 中华麻醉学杂志

Objective:To evaluate the effect of low-dose esketamine on postoperative delirium (POD) in elderly frail patients undergoing laparoscopic radical resection of the gastrointestinal tumor.Methods:Ninety-four American Society of Anesthesiologists physical status Ⅱ or Ⅲ frail patients of both sexes, aged 65-80 yr, with body mass index of 18.5-30.0 kg/m 2 and preoperative Fried frailty phenotype scale score≥3, scheduled for elective laparoscopic radical resection of the gastrointestinal tumor under general anesthesia, were divided into 2 groups ( n=47 each) using a random number table method: control group (group C) and low-dose esketamine group (group K). In group K, esketamine 0.5 mg/kg was given during induction of anesthesia, and esketamine 0.25 mg·kg -1·h -1 was continuously infused during operation until the end of operation.In group C, the equal volume of normal saline was given at the corresponding time point.After induction of anesthesia and before skin incision (T 1), at 1 day after operation (T 2) and at 3 days after operation (T 3), blood samples from the internal jugular vein were collected for determination of the concentrations of S100β protein and neuron-specific enolase (NSE) in serum by enzyme-linked immunosorbent assay.The intraoperative consumption of propofol, remifentanil and sufentanil and use of vasoactive drugs were recorded.POD was evaluated by Confusion Assessment Method within 3 days after operation. Results:Compared with the baseline at T 1, the concentrations of serum S100β and NSE were significantly increased at T 2, 3 in both groups ( P<0.05). Compared with group C, the incidence of POD was significantly decreased (30% vs.13%), the intraoperative consumption of propofol and remifentanil was decreased, and concentrations of serum S100β protein and NSE were decreased at T 2, 3 in group K ( P<0.05). Conclusions:Low-dose esketamine can decrease the occurrence of POD in elderly frail patients undergoing laparoscopic radical resection of gastrointestinal tumor.

Influencing factors of protein energy wasting in maintenance hemodialysis patients / 国际生物医学工程杂志

Objective:To explore the main risk factors of protein energy expenditure (PEW) in maintenance hemodialysis (MHD) patients.Methods:According to diagnostic criteria, 166 patients with MHD were divided into PEW group and control group. The general clinical data, physical indexes, and physical and chemical analysis results of all patients was collected, and the differences in indexes between the two groups of patients were compared. Logistic analysis was used to find the risk factors of MHD combined with PEW.Results:There were statistically significant differences in blood pressure, protein intake, vitamin intake, and uric acid, creatinine, blood calcium levels between the PEW group and the control group (all P<0.05). Multivariate logistic regression analysis showed that blood pressure, daily sleep time, whether to take vitamins, body mass index (BMI), creatinine and parathyroid hormone (PTH) were the risk factors of MHD combined with PEW. Conclusions:In clinical practice, more attention should be paid to controlling blood pressure, improving sleep, and supplementing vitamins in patients with MHD.

Malnutrition in liver cirrhosis: Benefits from improving portal hypertension / 临床肝胆病杂志

Malnutrition is common in patients with liver cirrhosis, especially with a high incidence rate in the decompensated stage, which mainly manifests as protein-energy malnutrition and has a negative impact on the prognosis of patients. The main causes of malnutrition in liver cirrhosis are insufficient intake and increased consumption. Body composition assessment is an important method to evaluate the type of malnutrition in liver cirrhosis. European Society for Parenteral and Enteral Nutrition (ESPEN) guidelines suggest that Nutritional Risk Screening 2002 (NRS2002) should be used for nutritional risk screening, and cirrhotic patients with an NRS2002 score of ≥3 are considered at the risk of malnutrition. ESPEN guidelines recommend a daily energy intake of 30-35 kcal/kg and a daily protein intake of 1.2-1.5 g/kg for patients with liver cirrhosis. Transjugular intrahepatic portosystemic shunt can effectively reduce portal hypertension in patients with liver cirrhosis and help to improve their nutritional status.

Desnutrição na cirrose: associação com a etiologia e disfunção hepatocelular / Malnutrition in cirrhosis: association with etiology and hepatocellular dysfunction

ABSTRACT BACKGROUND: The protein-energy malnutrition alters the prognosis of patients with cirrhosis. Its prevalence may vary according to the etiology of liver disease, it´s severity and the evaluation of the method applied. The infection by the hepatitis C virus (HCV) and alcoholism are the main etiologies of cirrhosis and result in a significant morbidity and mortality. OBJECTIVE: To evaluate the nutritional status of patients with cirrhosis according the liver disease etiology and severity. METHODS: It is a prospective study, in which the sample was for convenience and consisted of patients with cirrhosis, infected by HCV or alcoholic etiology. The nutritional status evaluation was carried out through anthropometry, food consumption, bioelectrical impedance (BIA) and subjective global assessment (SGA). The anthropometric data evaluated were weight, height, body mass index (BMI), triceps skinfold (TSF), circumference of the arm (CA), non-dominant handshake strength (FAM) and the adductor pollicis muscle thickness (APM). Patients were classified according to the severity of liver disease, using the Child-Pugh and Model for End-stage Liver Diseases (MELD) scores. RESULTS: Ninety patients with cirrhosis were evaluated, 47 with HCV and 43 with alcoholic etiology. The prevalence of protein-calorie malnutrition ranged from 10.9% to 54.3% in the HCV group and from 4.7% to 20.9% in the alcoholic group, depending on the method used for evaluation. The group with HCV infection presented a higher malnutrition prevalence in comparison to the alcoholic in the following evaluations: TSF (P<0.001), phase angle (PA) (P=0.016) and SGA (P=0.010). PA values were lower in patients with viral cirrhosis (5.68±1.05) when compared to those with alcoholic etiology (6.61±2.31) (P=0.016). When all patients were analyzed, regardless of etiology, an inversely correlation was observed among Child-Pugh score and PA values (P=0.018). CONCLUSION: HCV cirrhosis showed worse nutritional parameters in comparison to alcoholic etiology; however, the PA was associated with worse liver function in both etiologies.

RESUMO CONTEXTO: A desnutrição proteico-calórica altera o prognóstico dos pacientes com cirrose. Sua prevalência pode variar de acordo com a etiologia da hepatopatia, gravidade da doença e o método de avaliação empregado. A infeção pelo vírus da hepatite C (VHC) e o alcoolismo, estão entre as principais etiologias da cirrose e acarretam significativa morbidade e mortalidade. OBJETIVO: Avaliar o estado nutricional do paciente com cirrose de acordo com a etiologia e gravidade da hepatopatia. MÉTODOS: Estudo prospectivo, em que a amostra foi por conveniência constituída de pacientes com cirrose, infectados pelo vírus da hepatite C (VHC) ou etiologia alcoólica. A avaliação do estado nutricional foi realizada através da antropometria, consumo alimentar, bioimpedância elétrica (BIA) e da avaliação subjetiva global (ASG). Os dados antropométricos avaliados foram: peso, altura, índice de massa corporal (IMC), prega cutânea triciptal (PCT), circunferências do braço (CB), força do aperto de mão não dominante (FAM) e a espessura do músculo adutor do polegar (MAP). Os pacientes foram classificados de acordo com a gravidade da hepatopatia, através do escore Child-Pugh e Model for End-stage Liver Diseases (MELD). RESULTADOS: Foram avaliados 90 pacientes com cirrose, 47 com etiologia pelo VHC e 43 com etiologia alcoólica. A prevalência de desnutrição proteico-calórica variou de 10,9% a 54,3% no grupo do VHC e de 4,7% a 20,9% no grupo dos alcoolistas, dependendo do método utilizado para avaliação. O grupo com infecção pelo VHC apresentou maior prevalência de desnutrição em relação ao de etiologia alcoólica nas seguintes avaliações: PCT (P<0,001), ângulo de fase (AF) (P=0,016) e ASG (P=0,010). Os valores do AF foram menores nos pacientes com cirrose viral (5,68±1,05) quando comparados aos com etiologia alcoólica (6,61±2,31) (P=0,016). Quando analisados todos os pacientes, independente da etiologia da hepatopatia, observou-se uma correlação inversamente proporcional entre a classificação de Child-Pugh e os valores de AF (P=0,018). CONCLUSÃO: A cirrose pelo VHC demonstrou piores parâmetros nutricionais em relação à etiologia alcoólica; entretanto, em ambas etiologias o AF foi associado com pior função hepática em ambas etiologias.

Serum albumin and total protein level as plausible marker for diagnosis of protein energy malnutrition in children under age 5 years

Background: The circulating concentration of transport protein, traditionally albumin, has been used to define protein deficiency. However, few studies have been conducted to see if there is any correlation between serum total protein and albumin levels in children with PEM. Hence the study was planned to estimate serum total protein, serum albumin levels in children with PEM and healthy controls.Methods: All the children were divided in two groups. Case Group A consist of 250 children with protein energy malnutrition and control Group B consist of healthy 250 children. Venous blood of amount 3 ml was collected with full aseptic precautions. The blood was collected in the EDTA vacutainer and test tube. Serum total protein was estimated by Biuret method, serum albumin was estimated by Bromocresol green dye method (BCG dye).Results: When the mean serum levels of albumin levels and the total protein levels were measured in the controls as well as case groups, there was decrease in levels in case group as compared to control group. This difference of decrease when evaluated statistically it was found to be statistically significant. When the albumin/globulin ratio was calculated in both the groups, it was found to be statistically lower in case group as compared to control group. PEM children have low serum total protein and albumin levels as compared to healthy controls (p<0.001), this is probably due to decreased intake of proteins and reduced biosynthesis. PEM children have lower hemoglobin levels as compared to healthy controls; this is probably due to deficiency of iron and other micronutrients, which is often found in a child with malnutrition.Conclusions: Early diagnosis and prompt management of PEM and its complications can prevent development of permanent physical and mental retardation.

Etiología y mecanismos de desnutrición en el paciente cirrótico / Etiology and mechanisms of undernourishment in the cirrhotic patient

RESUMEN El hígado juega un rol en la homeostasis calórica; está comprometido en el proceso digestivo, y es frecuente encontrar desnutrición en la cirrosis, por incapacidad para satisfacer sus requerimientos de macro y micronutrientes. La patogénesis de desnutrición en la cirrosis es multifactorial, compleja y difícil de ser comprendida, incluye ingesta reducida de nutrientes, biosíntesis disminuida, aumento de la perdida de proteína, absorción intestinal deficiente, disturbios en la utilización del substrato, anormalidades en el metabolismo de carbohidratos, lípidos y proteínas así como aumento de citoquinas pro inflamatorias, resultando en hipermetabolismo y aumento del gasto proteína-energía y de los requerimientos. La evaluación nutricional es trascendental para un enfoque clínico-terapéutico, por su implicancia pronóstica y la respuesta al trasplante hepático. Aún con la evidencia de la prevalencia de desnutrición en cirróticos, continúa poco reconocida, poco diagnosticada y muy poco tratada. Existe controversia si la desnutrición puede ser revertida en cirróticos; aunque hay un acuerdo sobre la necesidad de mejorar la ingesta de alimentos evitando las limitaciones y restricciones no basadas en la evidencia.

ABSTRACT The liver plays a role in the caloric homeostasis; it is involved in the digestive process, so it is not surprising to find malnutrition in cirrhosis, because they have an inability to meet their macro and micronutrient requirements. The pathogenesis of malnutrition is multifactorial and complex and frequently difficult to understand and includes reduced nutrient intake, decreased protein biosynthesis and increased loss, poor intestinal absorption, disturbances in the use of the substrate, abnormalities in the metabolism of carbohydrates, lipids and proteins and increased of pro-inflammatory cytokines resulting in a hypermetabolic state as well as increase in protein-energy expenditure and requirements. The evaluation of nutritional status is transcendental for a clinical-therapeutic approach, due to its influence on the prognosis and response to liver transplantation. Despite the evidence on the prevalence of malnutrition in liver cirrhosis, this condition remains poorly recognized, poorly diagnosed and poorly treated. It is controversial, if malnutrition can be reversed in cirrhotic; there is an agreement about the need to improve the food intake, avoiding limitations and restrictions that are not based on evidence.

Anorexia nervosa con desenlace fatal: a propósito de un caso / Anorexia nervosa with fatal outcome: A case report

Resumen La Anorexia Nervosa (AN) es el trastorno psiquiátrico con mayor nivel de mortalidad directa y, a la vez, causa de múltiples y riesgosas complicaciones somáticas tales como: bradicardia, hipotensión ortostática, arritmias cardiacas, hipoglicemia, falla hepática, alteraciones hidroelectrolíticas y hormonales, osteopenia, dilatación gástrica y, finalmente, muerte súbita por diferentes causas. A pesar de su prevalencia relativamente baja, afecta a personas jóvenes con larga expectativa de vida. Su manejo, cuando llega a niveles de gravedad severa (IMC < 15), es complejo, pues requiere trabajo conjunto de psiquiatría y otras especialidades médicas y puede tener consecuencias ominosas. Se presenta y discute el caso de una paciente mujer de 19 años cuyo IMC llegó a 11 y que, lamentablemente, falleció mientras recibía atención hospitalaria. Se revisan las principales complicaciones médicas de la AN, remarcándose la necesidad de considerar los parámetros pertinentes para una atención hospitalaria oportuna que pueda evitar desenlaces fatales.

Summary Anorexia Nervosa (AN) is the psychiatric disorder with the highest direct mortality level and, at the same time, the cause of multiple and risky somatic complications such as bradycardia, orthostatic hypotension, cardiac arrhythmias, hypoglycemia, liver failure, hydro-electrolytic and hormonal disorders, osteopenia, gastric dilation and, finally, sudden death from different causes. Despite its relatively low prevalence, it affects young people with a long life expectancy. Its medical management, when reaching a high severity level (BMI <15), is complex as it requires joint work between psychiatry and other medical specialties, and can even have ominous consequences. The case of a 19-year-old woman whose BMI was around 11, and who unfortunately died while receiving hospital care, is discussed. The main complications of AN are reviewed, and the need to consider the relevant parameters for a timely hospital care are highlighted, in order to avoid fatal outcomes.

Study on the Improvement Effects of Sijunzi Decoction on Chronic Kidney Disease-protein Energy Wasting Model Mice and Its Mecranism / 中国药房

OBJECTIVE：To study the improvement effects of Sijunzi decoction on skeletal muscle atrophy in chronic kidney disease-protein energy wasting （CKD-PEW）model mice ，and to explore its potential mechanism . METHODS ：A total of 80 mice were randomly divided into sham operation group （n＝10）and modeling group （n＝70）. CKD-PEW model was established by removing 5/6 kidneys and giving a low-protein diet （4％ casein）for mice in modeling group. Totally 50 modeled mice were randomly divided into model group ，Sijunzi decoction low-dose ，medium-dose and high-dose groups [ 2.34，4.68，9.36 g/（kg·d）， by crude drug] ，Compound α-ketoacid tablets group [positive control ，1 g/（kg·d）]，with 10 mice in each group. Administration groups were given relevant medicine intragastrically ；sham operation group and model group were given constant volume of normal saline intragastrically ，once a day ，for consecutive 14 d. After last medication ，body weight of mice and wet mass of left tibialis anterior muscle （TA）were weighed ；TA cross-sectional area was determined ；protein synthesis and decomposition metabolism ability of TA were detected ；mRNA expressions of Bcl-2，Bax and Caspase-3 in TA were detected by Real-time PCR ；protein expressions of muscular dystrophin Fbox- 1 （Atrogin-1），myofloin-1 （MuRF-1），Rho-related protein kinase 1 （ROCK1）， phosphorylated PTEN （p-PTEN），phosphatidylinositol-3-kinase（PI3K）and phosphorylated Akt （p-Akt）in TA were detected by Western blotting. RESULTS ：Compared with the sham operation group ，the body weight ，TA wet weight ，protein synthesis metabolism ability of TA as well as protein expressions of PI 3K and p-Akt were decreased significantly in model group （P＜0.05）； the cross-sectional area of TA decreased significantly （P＜0.05）；protein decomposition metabolism ability of TA ，Bax/Bcl-2 ratio， Caspase-3 mRNA expression ，protein expressions of Atrogin- 1，MuRF-1，ROCK1 and p-PTEN were increased significantly （P＜ 0.05）. Compared with model group ，above indexes of mice were all improved significantly in Sijunzi decoction medium-dose ， high-dose groups and Compound α-ketoacid tablets group （P＜0.05）. CONCLUSIONS ：Sijunzi decoction can increase the body weight of CKD-PEW model mice and alleviate the skeletal atrophy ；the mechanism may be related to regulating ROCK 1/PTEN/Akt signaling pathway activity ，inhibiting the expression of Atrogin- 1 and MuRF- 1.

Study on impact of protein energy malnutrition on development in children

Background: Majority of the children in India who live below the poverty line in an environment of deprivation and starvation have physical and developmental retardation. The Objective of this study to study the impact and comparison of protein energy malnutrition on the development with normal children.Methods: This was a hospital based cross sectional study in which total 128 cases of protein energy malnutrition and 30 normal children were enrolled from nutritional rehabilitation center and in patients wards. The study population comprised of children less than 5 years of age, having weight for height/length ?3 SD, with visible wasting, or bipedal oedema, with mid arm circumference <11.5 cm were assessed for their development in all four domains using Denver II developmental Screening Test (DDST-II).Results: The gross motor milestones are affected in 62.5% with grade4 PEM & 42.85% with grade 3, the fine motor component is affected more in grade 4 with other domains less affected, no significant relation of language delay with PEM was observed in this study, 40% of children with grade 4 PEM shows delay in social domain while 18.18% of the patients with grade 3 PEM show delay in social domain. No patients with grade 1 or grade 2 PEM showed delay in social domain. All four domains are affected in PEM with a maximum effect in gross motor, but the difference does not seem to be significant as the p value is 0.3 i.e.' >0.05 which is insignificant.Conclusions: My study on the effect of protein energy malnutrition on development proves that there in increasing delay in all the domains of development with increasing grade of malnutrition. Early detection of malnutrition in community can cause early intervention and increase the productivity of nation.

Essential fatty acid deficiency was observed in 56(10.9%) adolescents.Conclusions: High prevalence of nutritional deficiencies among these adolescents needs great attention and health education.

Análise bioeconômica de períodos de suplementação proteico-energética na estação seca para novilhas Nelore em pastagem diferida de Urochloa decumbens / Bioeconomic analysis of protein-energy supplementation periods in dry season for Nellore heifers in stockpiled pastures of Urochloa decumbens

A suplementação proteico-energética (SPE) é uma estratégia adequada à bovinocultura de corte no período seco do ano, embora sua adoção equivocada possa comprometer seu benefício/custo. O objetivo deste estudo foi avaliar o desempenho de novilhas Nelore em pastagem diferida de Urochloa decumbens sob dois períodos de SPE, e realizar análise econômica desses sistemas de produção. O experimento foi conduzido sob delineamento inteiramente ao acaso, com 147 e 55 dias de SPE (sistemas 1 e 2, respectivamente), de 21/06 a 15/11/2016, com 16 e 20 novilhas nos sistemas 1 e 2, respectivamente. Os dados de desempenho foram analisados utilizando-se o PROC MIXED do SAS®, e as médias comparadas por PDIFF (P<0,05). Os pesos médios foram semelhantes (P>0,05) entre os sistemas de produção nas pesagens de 21/06, 12/07, 02/08, 23/08 e 15/11/2016. Os valores presentes líquidos foram positivos sob a taxa anual de desconto de 4%, sendo viáveis financeiramente. Por apresentarem taxa interna de retorno superior à taxa mínima de atratividade, os sistemas foram atrativos para investimento. Foi obtido balanço econômico positivo de R$ 25,26/animal para substituição do sistema 1 pelo sistema 2. A redução de 92 dias na SPE proporciona desempenho semelhante entre novilhas e maior eficiência econômica do sistema de produção.(AU)

Protein-energy supplementation (SPE) is an adequate strategy for beef cattle during drought season of the year, although the wrong adoption might compromise its cost/benefit ratio. The aim of this study was to evaluate Nellore heifers' performance under SPE periods and to draw economic analysis of production systems. The experiment was conducted under a completely randomized design, with two systems: 147 and 55 days of SPE (Systems 1 and 2), from 06/21/2016 to 11/15/2016, with 16 and 20 heifers to Systems 1 and 2, respectively. Performance data were analyzed by SAS® PROC MIXED and means compared by PDIFF (P< 0.05). The weight means were similar between the production systems (P> 0.05) at weighing of 06/21, 07/12, 08/02, 08/23 and 11/15/2016. The net present values were positive under annual discount rate of 4%, being financially viable. By presenting internal return rate higher than the minimum attractiveness rate, the systems were attractive for investment. Positive economic balance was obtained of R$ 25.26/animal to replace System 1 by 2. The reduction of 92 days in SPE provides similar performance between Nellore heifers and greater economic efficiency of the production system.(AU)

Combating protein energy wasting in end stage kidney disease: role of exogenous proteolytic enzyme as an adjuvant to dietary protein

Background: Despite interventions, the prevalence of protein energy wasting in patients on dialysis continues to be unacceptably high. The objective of the study is to evaluate the efficacy of exogenous proteolytic enzyme Aminace 70000 (Hemoglobin Tyrosine Unit), as an adjuvant to dietary protein in improving the nutritional status.Methods: This is a retrospective, real world, single centre, observational study, aimed at assessing the changes in key nutritional indices, over 6 months in patients with chronic kidney disease (CKD) initiated on continuous ambulatory peritoneal dialysis (CAPD). The intervention included addition of egg protein and use of an exogenous proteolytic enzyme. Three cohorts were identified. Cohort 1, had access to a nephrologist and CAPD counsellor; Cohort 2, in addition had access to a dietician who emphasized the need for increase in dietary protein in form of 4-6 eggs a day; and cohort 3, were in addition given an exogenous proteolytic enzyme with the major protein meal.Results: The absolute fall in serum albumin at 6 months for the cohort 1, 2 and 3 is 0.48, 0.29 and 0.09 gm/dl respectively. Not only was the fall in serum albumin significantly less with the use of exogenous proteolytic enzyme, a higher proportion of patients were able to maintain or improve their serum albumin. The fall in midarm circumference was maximum in cohort 1 (2.08 cm) and least in cohort 3 (0.45 cm). This positive trend however, did not achieve statistical significance.Conclusions: Use of exogenous proteolytic enzyme, when combined with egg protein, improves key nutritional indices in patients of CKD on CAPD.

Zinc Supplementation for Promoting Growth in Children Under 5 years of age in Low- and Middle-income Countries: A Systematic Review

Objective: To study the effect of zinc supplementation in children under 5 years of age from low- and middle-income countries (LMICs) onanthropometry and prevalence of malnutrition.Design: Systematic review of randomized controlled trials and cluster randomized trials.Setting: Low- and middle-income countries.Participants: 63 trials with zinc supplementation, incorporating data on 27372 children. Trials conducted exclusively in specificallydiseased participants and in children with severe acute malnutrition were excluded.Intervention: Zinc supplementation, provided either as medicinal supplementation or through food fortification.Outcome Measures: (i) Anthropometry: weight, height, weight-for-height, mid-arm circumference, head circumference; (ii) Prevalenceof malnutrition.Results: There was no evidence of effect on height-for-age Z score at the end of supplementation period (25 trials; 9165 participants;MD= 0.00 Z; 95% CI -0.07, 0.07; P=0.98; moderate quality evidence) with significant heterogeneity (I² = 57%; P<0.001) related to doseand duration of zinc between trials. There was little or no effect on change in height-for-age Z score (13 trials; 8852 participants; MD= 0.11Z; 95% CI -0.00, 0.21; P=0.05), but the heterogeneity was considerable (I²=94%; P<0.001). There was no evidence of effect on length(6303 participants; MD= 1.18 cm; 95% CI -0.63, 2.99 cm, P=0.20; moderate quality evidence; considerable heterogeneity, I²=99%) but alittle positive effect on change in length (19 trials; 10783 participants; MD= 0.43 cm; 95% CI 0.16, 0.70, P=0.002; moderate qualityevidence; considerable heterogeneity, I²=93%). There was no evidence of effect on weight-for-age Z score or change in weight-for-age Zscore but a little positive effect on weight (19 trials; 8851 study participants; MD= 0.23 kg; 95% CI 0.03, 0.42; P=0.02; considerableheterogeneity, I²=91%) and change in weight (kg) (23 trials; 10143 study participants; MD= 0.11 kg; 95% CI 0.05, 0.17, P<0.001,substantial heterogeneity, I²=80%). There was no evidence of effect on weight-for-height Z score, and mid upper arm circumference at theend of supplementation period, but there was a little positive effect on change in mid-arm circumference from baseline (8 trials; 1724participants; MD = 0.09 cm; 95% CI 0.01, 0.16; P=0.03; no heterogeneity, I²=0%). Head circumference in zinc supplemented group wasmarginally higher compared to control (2966 study participants; MD= 0.39 cm; 95% CI 0.03, 0.75; P=0.03; substantial heterogeneity,I²=67%). There was no evidence of benefit in stunting (10 trials; 11838 study participants; RR= 1.0; 95% CI 0.95, 1.06; P=0.89; moderatequality evidence; no significant heterogeneity, I²=11%), wasting (7 trials; 8988 study participants; RR= 0.94; 95% CI 0.82, 1.06; P=0.31;moderate quality evidence; no significant heterogeneity, I²=13%) or underweight (7 trials; 8677 study participants; RR= 1.08; 95% CI 0.96,1.21; P=0.19; moderate quality evidence; substantial heterogeneity, I²=73%).Conclusion: Available evidence suggests that zinc supplementation probably leads to little or no improvement in anthropometric indicesand malnutrition (stunting, underweight and wasting) in children under five years of age in LMICs. Advocating zinc supplementation as apublic health measure to improve growth, therefore, appears unjustified in these settings with scarce resources.
