Evaluation of perioperative nutritional status and body composition in patients with stomach neoplasms / 中国实用护理杂志

Objective:To investigate the nutritional risk, incidence of malnutrition, and intake of three major energy-supplying nutrients, analyze changes in their body composition and the possible influencing factors in patients with stomach neoplasms during perioperative period in order to provide a theoretical basis for the nutritional management of patients with stomach neoplasms during perioperative period.Methods:This was a cross-sectional study. A total of 105 patients who underwent gastric cancer radical surgery in the Gastrointestinal Department of Zhongshan Hospital Affiliated to Xiamen University from June 2021 to May 2023 were taken as the research subjects using fixed-point continuous sampling method. They were recruited for screening and assessment using Nutritional Risk Screening 2002 (NRS 2002) and Patient-Generated Subjective Global Assessment (PG-SGA). Nutrients intake during the perioperative period were investigated using the 24-h recall method and dietary diary method, etc. Body compositions were measured using the bioelectrical resistance method.Results:Among the 105 patients, there were 78 males and 27 females, with an average age of (61.5 ± 10.3) years. About 83.8% (88/105) gastric cancer patients were at nutritional risk and 82.9% (87/105) were malnourished. The preoperative and postoperative energy intake were (1 646.1 ± 321.5) and (1 317.2 ± 365.8) kcal (1 kcal=4.184 kJ), respectively, which were significantly lower than the target amount of (1 896.7 ± 262.9) kcal, the difference was statistically significant ( t=6.23, 8.29, both P<0.05).The preoperative body mass, muscle mass, skeletal muscle, fat mass, and skeletal muscle index were (51.5 ± 9.6), (40.8 ± 6.0), (23.6 ± 4.0), (8.3 ± 4.9) kg, and 6.7 ± 0.8 respectively, while the postoperative values were (50.0 ± 9.1), (39.8 ± 6.0), (22.8 ± 3.6), (7.8 ± 5.2) kg, and 6.5 ± 0.8 respectively, with statistically significant differences between the two groups ( t values were 2.89-10.61, all P<0.05). Logistic multivariate regression analysis showed that the operation time ( OR=3.984, 95% CI 1.433-11.080, P<0.05) and energy satisfaction ( OR=0.053, 95% CI 0.005-0.610, P<0.05) were independent influencing factors for the degree of skeletal muscle loss. Conclusions:During perioperative period, the gastric cancer patients had poor nutritional status with insufficient nutrient intake and accelerated loss of body muscle and fat. Therefore, it was necessary to conduct a comprehensive nutritional evaluation for patients with stomach neoplasms during perioperative period in time and take steps to promote recovery by providing individualized nutritional therapy.

Relationship between perioperative nutrition risk and venous thromboembolism in patients with hip fracture / 天津医药

Objective To investigate the relationship between perioperative nutritional risk and venous thromboembolism(VTE)in patients with hip fracture.Methods A total of 379 patients with unilateral hip fracture due to fall or sprain who underwent elective surgery were selected and divided into the non-VTE group(246 cases)and the VTE group(133 cases)according to whether or not VTE occurred during perioperative period.Basic information,surgical and anesthesia records,nutritional risk related indicators,inflammatory indicators and outcome indicators of patients were collected.Multiple Logistic regression was used to analyze the independent influencing factors of perioperative VTE.Receiver operating characteristics(ROC)curves were used to assess the ability to discriminate independent factors,and DeLong test was used to compare area under the curve(AUC).Results Compared with the non-VTE group,the proportion of patients in the VTE group was older,complicated with hypertension,the time to visit hospital more than 2 days,received(hollow/intramedullary nail)internal fixation,perioperative blood transfusion,ASA gradeⅢtoⅣ,and higher nutritional risk screening Table(NRS)-2002 scores on admission and higher postoperative neutrophil/lymphocyte ratio(NLR).Nutritional prognosis index(PNI),hemoglobin(Hb)and prealbumin(PA)at admission and after operation were lower in the VTE group than those in the non-VTE group(P＜0.01).Multivariate Logistic regression analysis showed that PNI was decreased,NRS-2002 scores and PA were increased,and the time of visit hospital was>2 days after internal fixation.American College of Anesthesiologists(ASA)gradesⅢ-Ⅳwere independent risk factors for perioperative VTE of hip fracture(P＜0.05).ROC curve analysis showed that the AUC(95%CI)of NRS-2002 at admission was 0.739(0.692-0.783),and that of PNI at admission was 0.720(0.672-0.765),both of which were better than other influencing factors(P＜0.01).Conclusion NRS-2002 and PNI are good predictors of perioperative VTE in patients with hip fracture.

Perfil de pacientes adultos hospitalizados por COVID-19 antes y después de la introducción de las vacunas contra SARS-CoV-2 / Profile of adult patients hospitalized with COVID-19 before and after the introduction of vaccines against SARS-CoV-2

INTRODUCCIÓN: La introducción progresiva de vacunas contra SARS-CoV-2 a partir de 2021, priorizando grupos de mayor edad, podría implicar un cambio en el perfil de pacientes hospitalizados por COVID-19 en el tiempo. OBJETIVO: Comparar las características y evolución de pacientes adultos hospitalizados por COVID-19 en un período anterior en 2020 (PER1) y otro posterior al inicio de la vacunación masiva contra SARS-CoV-2 (PER2). PACIENTES Y MÉTODOS: Se registró edad, género, comorbilidades, complicaciones y evolución de los pacientes hospitalizados por COVID-19 en una clínica privada, en Santiago, Chile. Se calculó el puntaje de gravedad y riesgo nutricional. RESULTADOS: En PER2, los pacientes fueron de menor edad, pero con comorbilidades similares al PER1, excepto por mayor malnutrición por exceso. Los pacientes del PER2 no vacunados requirieron más ventilación mecánica (38,9 vs. 14,3%, p = 0,03) y evolucionaron más gravemente (puntaje 6) que aquellos adecuadamente inmunizados (puntaje 5, p = 0,048). Las variables que más predijeron mortalidad fueron edad > 60 años (OR 28.995) y presencia de riesgo nutricional (OR 5.246). DISCUSIÓN: El cambio en el perfil y evolución de los pacientes hospitalizados con COVID-19 está asociado con la secuencia de priorización de vacunas contra SARS-CoV-2, cuyo efecto redujo las hospitalizaciones y gravedad de COVID-19 en adultos mayores.

BACKGROUND: During the COVID-19 pandemic, the early prioritization of SARS-CoV-2 vaccines for older adults may have affected the characteristics of hospitalized COVID-19 patients over time. AIM: To compare the clinical characteristics and outcomes of adult patients admitted for COVID-19 before (PER1) and after (PER2) the initiation of mass vaccination for SARS-CoV-2. METHODS: Data on age, gender, comorbidities, complications, and outcomes of adult patients hospitalized for COVID-19 in a private clinic of Santiago, Chile, were collected. Scores for COVID-19 severity and nutritional risk were calculated. RESULTS: In PER2, patients were younger but had similar comorbidities, except for a higher prevalence of overweight and obesity compared to PER1. Unvaccinated COVID-19 patients in PER2 required more invasive ventilatory support (38.9% vs. 14.3%, p = 0.03) and had a higher severity score (six) than vaccinated patients (five, p = 0.048). The variables that best predicted mortality were age > 60 years (OR 28,995) and the presence of nutritional risk (OR 5,246). DISCUSSION: Changes in the profile and outcomes of hospitalized patients during the COVID-19 pandemic are associated with the prioritization of SARS-CoV-2 vaccines and their protective effect in reducing hospitalizations and disease severity in older adults.

Applicability of Modified Pediatric Nutritional Risk Screening Tool in children with cerebral palsy / 中华实用儿科临床杂志

Objective:To explore the scheme of assigning rational scores to the Modified Pediatric Nutritional Risk Screening Tool for children with cerebral palsy(CP) at different Gross Motor Function Classification System(GMFCS) levels.Methods:The clinical data of 360 children with CP hospitalized in the Department of Children′s Rehabilitation, the Third Affiliated Hospital of Zhengzhou University from January to October 2019 were analyzed retrospectively.All the CP children at different GMFCS levels who met the inclusion criteria were subject to nutrition screening and assessment by using the Modified Pediatric Nutritional Risk Screening Tool and the Subjective Global Nutritional Assessment(SGNA) scale.The distribution of malnutrition rates assessed by the SGNA scale among the children at different GMFCS levels was examined.Data between groups were compared by the χ2 test.Children at different GMFCS levels were divided into different subgroups according to the statistical difference.Then, 0 or 1 score was assigned to the Modified Pediatric Nutritional Risk Screening Tool in different subgroups, and different combinations were formed.The nutritional risk screening results of different combinations were evaluated by using the SGNA scale assessment results as a reference. Results:In children with CP, the risk detection rate and incidence rate of malnutrition were 58.1%(209/360) and 36.9%(133/360), respectively.There was no significant difference in the incidence rate of malnutrition between GMFCS Ⅱ and GMFCS Ⅲ, as well as between GMFCS Ⅳ and GMFCS Ⅴ(all P>0.05). Therefore, children with CP were divided into 3 subgroups, namely, group Ⅰ, group Ⅱ to Ⅲ, and group Ⅳ to Ⅴ.Different CP disease scores were given to the Modified Pediatric Nutritional Risk Screening Tool in 3 subgroups, forming 3 different protocols[protocol 1 (0, 0, 1 point); protocol 2(0, 1, 1 point); current protocol (1, 1, 1 point)]. Taking the SGNA scale assessment results as a reference, the sensitivity of protocol 1, protocol 2 and current protocol were 85.7%, 92.5%, and 93.2% respectively.The specificity protocol 1, protocol 2 and current protocol were 81.1%, 78.0%, and 62.6%, respectively.And the Youden indexes of above three protocols were 0.668, 0.705, and 0.558, respectively.The Youden index of protocol 2 was relatively high. Conclusions:The Modified Pediatric Nutritional Risk Screening Tool can effectively identify the risk of malnutrition in children with CP.The scheme of assigning 0 points to children with GMFCS grade Ⅰ and 1 point to children with GMFCS grade Ⅱ to Ⅴ is more reasonable.

Consensus of nutritional management for survivors of malignant tumor (2023) / 中华临床营养杂志

Reasonable nutrition management is important in the long-term care of cancer survivors. It can contribute to reducing the risk of metabolic complications, improving patients' understanding, beliefs, and behavior as regards healthy lifestyles, promoting lifestyle and dietary changes, and positively impacting disease treatment and long-term prognosis. To improve the long-term management of Chinese cancer survivors, reduce medical costs, and maximize clinical benefits and patient outcomes, the Cancer Nutrition Branch of the Chinese Nutrition Society has developed this consensus based on the current cancer patient management and nutritional therapy in China, evidence-based medicine from domestic and foreign publications, as well as expert opinions and experiences in clinical and nutritional fields. Following the Oxford Centre for Evidence-based Medicine (OCEBM) grading system, this consensus provides recommendations for nutritional risk screening, assessment (diagnosis), enteral and parenteral nutrition support, and medical nutrition therapy for cancer survivors, aiming to inform and support the standardized nutritional management of cancer survivors.

The association of frailty status with nutritional risk and the effect on outcomes in elderly surgical inpatients / 中华临床营养杂志

Objective:To study the association of frailty status with nutritional risk and the effect on clinical outcomes among elderly surgical inpatients.Methods:Elderly inpatients from the surgery department of Beijing Hospital were enrolled from January to June 2021. Frail scale and nutritional risk screening 2002 (NRS 2002) were used for frailty evaluation and nutrition risk screening. The influence of frailty and associated nutrition risk in elderly surgical inpatients was analyzed.Results:487 elderly surgical patients were included, of whom 131 cases were in the non-frailty group, 279 cases were in the pre-frailty group and 77 cases were in the frailty group, according to the Frail scale score. 146 cases were at nutritional risk, of whom 8 (6.1% of 131) were in the non-frailty group, 87 (31.2% of 279) in the pre-frailty group and 51 (66.2% of 77) were in the frailty group. According to univariate/multivariate logistic regression analysis of frailty in elderly surgical patients, a higher NRS 2002 score, older age, and the presence of multiple concurrent diseases (≥ 5) were significantly associated with frailty ( P < 0.001). The Frail scale score was positively correlated with NRS 2002 score ( r = 0.448, P < 0.01). Multiple comparisons showed that frailty had statistically significant effects on hospital stay and medical costs in elderly surgical patients ( P < 0.05). Conclusions:The prevalence of frailty is higher in elderly surgical patients, and the prevalence of nutritional risk increases with the progression of frailty. Frailty can lead to prolonged hospital stays and increased hospital costs in elderly surgical patients.

Nutritional support therapy after GLIM criteria may neglect the benefit of reducing infection complications compared with NRS 2002-Re analysis based on a prospective cohort study / 中华临床营养杂志

The inconsistency of diagnostic criteria for malnutrition has confused clinicians since the 1980s. After the implementation of disease diagnosis related group payment (DRG) in China's public hospitals, the diagnosis of malnutrition and the correct documentation of nutrition-related diagnosis on the front sheet of medical records are related to the correct classification of the disease group and the medical insurance payment. Therefore, the reliable diagnostic criteria for malnutrition, especially disease-related malnutrition, is urgently needed in clinical practice. In September 2018, The global leadership Iinitiative on malnutrition (GLIM) diagnostic criteria consensus was launched. GLIM aimed to provide the explicit and unified diagnostic criteria for malnutrition in adult hospitalized patients. However, GLIM criteria was based on the voting by nutritional experts and was merely a consensus in nature. The clinical validity of GLIM criteria needs prospective verification, i.e., to demonstrate that patients with malnutrition as per GLIM criteria could have improved clinical outcomes with reasonable nutritional interventions. In November 2020, the article titled Nutritional support therapy after GLIM criteria may neglect the benefit of reducing infection complications compared with NRS 2002 was published on the journal Nutrition. It was the first study comparing nutritional risk screening 2002 (NRS 2002) and GLIM malnutrition diagnostic criteria among Chinese patients for the indication of nutritional support therapy. The clinical effectiveness of the two tools was retrospectively verified as well. Here we discussed the key points of this retrospective study, including the critical research methods, to inform the currently ongoing prospective validation of the GLIM malnutrition diagnostic criteria (the item of reduced muscle mass not included).

Nutritional risk and malnutrition in patients with gastrointestinal malignant tumors in day wards:a cross-sectional analysis / 肠外与肠内营养

Objective:This study investigated the nutritional risk and malnutrition of patients with digestive system malignant tumors in the day ward and evaluated the risk of comorbidity with nutritional risk and the risk factors of malnutrition in this population.Methods:A cross-sectional study was conducted to collect patients with malignant tumors of the digestive system who were admitted to the day ward of our hospital from November 23,2020,to December 14,2020.The Nutritional Risk Screening Form(NRS 2002)was used for nutritional risk screening,and the Subjective Assessment of Overall Nutritional Status(PG-SGA)was used to assess malnutrition,to investigate nutritional risk and prevalence of malnutrition,and to analyze potential influencing factors.Results:Among the 464 patients with malignant tumors of the digestive system in the day ward,the incidence of nutritional risk was 26.9％,the incidence of malnutrition was 34.7％,and the incidence of severe malnutrition was 14.2％.Multivariate analysis showed that patients with Karnofsky Performance Status(KPS)score＜90 and hypoproteinemia were more likely to have nutritional risk(P＜0.05).Patients with KPS score＜90 and chemotherapy cycles＞6 were more likely to be malnourished(P＜0.05).Conclusions:Digestive system malignant tumor patients in the day ward still have a high proportion of nutritional risks and malnutrition.For patients with KPS score＜90,hypoalbuminemia,and chemotherapy cycles＞6,nutrition issues should be given special attention.

Application of NRS 2002 and PG-SGA in Patients With Gastrointestinal Malignancies / 胃肠病学

Background:At present,domestic guidelines and consensus recommend the use of nutritional risk screening 2002(NRS 2002)and patient-generated subjective global assessment(PG-SGA)for nutritional risk screening and assessment of patients with gastrointestinal cancer during the perioperative period.However,PG-SGA has higher professional requirements,complex content and time-consuming.In the current busy situation of medical staff,NRS 2002 is more used for screening alone.Aims:To explore the consistency of NRS 2002 and PG-SGA in the assessment of nutritional status and clinical outcomes in patients with gastrointestinal malignancies,and to explore the accuracy of screening using NRS 2002 alone,so as to provide guidance for the establishment of clinical nutritional screening and assessment standards.Methods:A retrospective analysis was conducted on 157 patients with gastrointestinal malignancies who underwent radical operation in the Department of Gastrointestinal Surgery of Xiangya Hospital,Central South University from January 2020 to October 2022.Nutritional screening and evaluation were performed by NRS 2002 and PG-SGA scales and demographic data and nutrition-related laboratory indicators were collected to observe short-term postoperative clinical outcomes.Results:Patients with nutritional risk or malnutrition had lower body mass index(BMI),lymphocytes and prealbumin(P<0.05).The correlation and consistency of NRS 2002 and PG-SGA scales were good(r=0.728,κ=0.46)and the areas under the curve(AUC)for predicting postoperative complications were 0.691 and 0.702,respectively.In addition,nutritional risk and postoperative complications were significantly increased in patients with malnutrition(P<0.05).Conclusions:Therefore,gastrointestinal surgeons can only use NRS2002 to perform nutritional screening of patients and make corresponding nutritional treatment according to the screening results in the case of busy clinical work.

Predictive value of geriatric nutritional risk index in stroke-associated pneumonia / 中华老年心脑血管病杂志

Objective To investigate the predictive value of geriatric nutritional risk index(GNRI)for stroke-associated pneumonia in elderly patients with acute ischemic stroke(AIS).Methods A total of 1505 elderly patients with AIS admitted to Department of Neurology of the Second Affili-ated Hospital of Nanchang University from January 2017 to October 2022 were included in this retrospective study.According to GNRI nutritional assessment,they were divided into T1(high nutritional risk,GNRI＜82,n=49),T2(moderate nutritional risk,GNRI 82-91,n=305),T3(low nutritional risk,GNRI 92-98,n=555),and T4(no nutritional risk,GNRL＞98,n=596)groups.Additionally,based on the discharge diagnosis,they were further classified into pulmonary infection group(150 cases)and non-infection group(1355 cases).These subjects were also ran-domly assigned into training,validation,and testing sets in a ratio of 16∶4∶5.Multivariate logis-tic regression analysis was performed to identify the risk factors for pulmonary infection in stroke patients.Logistic regression and XGBoost algorithms were used to establish prediction models for pulmonary infection.The models were evaluated with their AUC value,accuracy,sensitivity,and specificity based on ROC curve analysis.Results Multivariate logistic regression analysis revealed that hypertension,invasive procedures,consciousness disorders,CRP,lymphocyte count,hemoglo-bin and GNRI were independent risk factors for pulmonary infection in stroke patients(P＜0.05).The AUC value of the GNRI model for predicting pulmonary infection in the testing set was 0.742(95％CI:0.651-0.833),with an accuracy of 71.8％,sensitivity of 76.7％,and specificity of 71.2％.The combined model of clinical indicators(hypertension,invasive procedures,conscious-ness disorders,CRP,lymphocyte count,hemoglobin)and GNRI achieved an AUC value of 0.776(95％CI:0.700-0.853),accuracy of 74.8％,sensitivity of 83.3％,and specificity of 73.8％in the test set.Conclusion GNRI is an independent risk factor for pulmonary infection in elderly pa-tients with AIS and has a certain value in predicting pulmonary infection after AIS.

Clinical evaluation of combined geriatric nutritional risk index and modified creatinine index predicting all-cause mortality in middle-aged and older patients undergoing maintenance hemodialysis / 中华肾脏病杂志

Objective:To explore the relationship between geriatric nutritional risk index (GNRI) and modified creatinine index (mCI) and all-cause mortality in maintenance hemodialysis (MHD) patients.Methods:It was a prospective cohort study. The MHD patients aged≥50 years old at hemodialysis centers of eleven hospitals in Beijing from April to June 2017 were selected as subjects. Baseline clinical data of the patients were collected. The patients were divided into high GNRI group (≥98) and low GNRI group (<98), and high mCI group (≥20.16 mg·kg -1·d -1) and low mCI group (<20.16 mg·kg -1·d -1), and further divided into 4 groups: G1 group (high GNRI and high mCI), G2 group (high GNRI and low mCI), G3 group (low GNRI and high mCI) and G4 group (low GNRI and low mCI). The differences of clinical characteristics among the four groups were compared. The patients were followed-up until June 2018 or death or loss, and the endpoint event was all-cause mortality. Kaplan-Meier survival analysis was used to compare the differences of the cumulative survival rates among the four groups. A multivariate Cox regression model was used to analyze the relationship between GNRI and mCI and all-cause mortality. Results:A total of 613 patients were included in the study, aged (63.65±7.78) years old (ranged from 50 to 81 years old), with 355 males (57.91%). The GNRI and mCI were (99.35±5.75) and (20.16±2.79) mg·kg -1·d -1, respectively. There were 232 patients (37.85%) in the G1 group, 177 patients (28.87%) in the G2 group, 95 patients (15.50%) in the G3 group, and 109 patients (17.78%) in the G4 group. There were statistically significant differences in age, sex, proportion of diabetes, proportion of coronary heart disease, body mass index, serum albumin and serum creatinine among the four groups (all P<0.05). A total of 69 patients (11.26%) died during a median follow-up time of 52(4, 52) weeks. Kaplan-Meier survival curve results showed that the mortality of patients with low GNRI was higher than that of patients with high GNRI (log-rank χ 2=26.956, P<0.001), and the mortality of patients with low mCI was higher than that of patients with high mCI (log-rank χ 2=25.842, P<0.001). The mortality was 3.45% in group G1, 10.73% in group G2, 9.47% in group G3, and 30.28% in group G4, and the differences among the four groups were statistically significant (log-rank χ 2=57.153, P<0.001). Multivariate Cox regression analysis results showed that as continuous variables, GNRI ( HR=0.911, 95% CI 0.882-0.941, P<0.001) and mCI ( HR=0.873, 95% CI 0.797-0.956, P=0.003) were correlated with all-cause death. As categorical variables, compared with high GNRI group and high mCI group, patients with low GNRI ( HR=3.469, 95% CI 2.125-5.665, P<0.001) and low mCI ( HR=3.255, 95% CI 1.879-5.640, P<0.001) had higher risks of death. Compared with G1 group, patients in G2 group ( HR=2.488, 95% CI 1.079-5.738, P=0.033) and G4 group ( HR=9.449, 95% CI 4.362-20.470, P<0.001) had higher risks of death. Conclusions:GNRI and mCI are independent predictive factors of all-cause mortality in MHD patients. The combination of GNRI and MCI can more accurately predict the risk of all-cause death in middle-aged and elderly MHD patients.

Progress on nutritional assessment and nutritional support for liver transplant recipients / 器官移植

Patients with end-stage liver disease after liver transplantation constantly suffer from malnutrition due to primary diseases and transplantation-related factors. Malnutrition will worsen clinical condition of the patients, increase the incidence of complication, length of hospital stay and medical expense after transplantation, and lower the survival rate. Sufficient nutritional support at all stages of liver transplantation is of significance. Accurate assessment of nutritional status and timely intervention are prerequisites for perioperative nutritional treatment in liver transplantation. In this article, the latest nutritional risk screening indexes and evaluation tools, nutritional support methods and other perioperative nutritional intervention measures for liver transplantation were reviewed, aiming to deepen the understanding and cognition of perioperative nutritional therapy for liver transplantation and provide reference for improving nutritional status and clinical prognosis of liver transplant recipients.

Correlation Between Nutritional Risk and Clinical and Endoscopic Features in Crohn's Disease Patients Treated With Biological Agents / 胃肠病学

Background: The widespread use of biological agents in recent years can improve the nutritional status of partial patients with Crohn's disease (CD) and change the course of the disease. Aims: To investigate the correlation between the nutritional risk and clinical and endoscopic features in CD patients treated with biological agents. Methods: Sixty⁃eight CD patients treated with biological agents from June 2021 to June 2022 at the First Affiliated Hospital of Anhui Medical University were enrolled. Nutritional risk screening was conducted by nutritional risk screening 2002 (NRS2002), and its correlation with clinical and endoscopic features was analyzed. Results: In 68 CD patients treated with biological agents, incidence of nutritional risk was 66.2%. There was statistically significant difference in incidence of nutritional risk in patients with different disease behaviors, SES⁃CD score and postoperative Rutgeerts score (all P0.05). Conclusions: The incidence of nutritional risk is high in CD patients treated with biological agents, and is correlated with CD disease behavior, SES ⁃ CD score, and postoperative Rutgeerts score.

Effects of food for specific medical purposes on muscle status, exercise capacity and nutrient metabolism in patients at nutritional risk / 中华临床营养杂志

Objective:To evaluate the effects of foods for special medical purposes (FSMP) on physical performance, body composition, nutritional metabolic indicator levels, and inflammatory factor levels in patients at nutritional risk.Methods:A single-center, double-blind, randomized, controlled clinical study was conducted. Patients at nutritional risk were randomized to two groups. Both groups received the nutritional management for 8 weeks, including 30 gram of nutritional preparations thrice a day, standard meals, and nutritional education. The intervention group was given full nutritional FSMP while the control group was given isocaloric placebo. The primary outcomes were the changes in timed up and go (TUG) test score, grip strength and muscle mass measured by bioelectrical impedance analysis after the intervention. The secondary outcomes were the walking speed as measured by 4-meter walk test, calf circumference, blood 25 hydroxyvitamin D 3 (25-OH-VD 3), and high-sensitivity C-reactive protein. Other indicators examined included serum albumin and prealbumin and inflammatory factors, and T cell and B cell subsets. Results:Forty-five patients were enrolled and 25 completed the intervention and follow-up period. There were no significant differences between groups in sex, age, height, and weight. Muscle mass ( P=0.042), upper limb muscle mass ( P=0.035), and grip strength ( P=0.032) were significantly increased in the intervention group compared to the control group, while TUG score was significantly reduced ( P=0.047). Four-meter walk test time, calf circumference, inflammatory indicators, and serum indicators did not change significantly after the intervention( P>0.05). TUG score was positively correlated with 4-meter walk time, interleukin-8, while negatively correlated with grip strength, 25-OH-VD 3 and serum albumin. Conclusions:The full nutritional FSMP was safe and effective for long term use in patients at nutritional risk, improving physical performance and muscle mass. However, no significant effect of full nutritional FSMP were observed on serum nutritional indicators and inflammatory factors.

A study on the correlation between nutritional status and length of hospital stay in patients with digestive disorders / 中华临床营养杂志

Objective:To study the correlation between nutritional status and length of hospital stay in patients with digestive disorders.Methods:The data were collected from the database of a multi-center investigation on the dynamic changes of nutritional status of hospitalized patients in China, a project led by the Geriatric Nutrition Support Group, Society of Parenteral and Enteral Nutrition, Chinese Medical Association. The enrolled patients were screened for malnutrition and possible sarcopenia using Global Leadership Initiative on Malnutrition criteria, and the dynamic changes of serum biochemical indexes during hospital stay and the effects of malnutrition and possible sarcopenia on the length and cost of hospital stay were analyzed.Results:A total of 1 180 patients were enrolled, with an average age of (56.3±16.1) years, the average height of (164.65±8.29) cm, and the average weight of (62.12±12.12) kg. There were significant differences in body weight, body mass index, calf circumference, lymphocyte count, triglyceride, hemoglobin, albumin and total protein between at discharge and at admission ( P<0.001). There might be a correlation between post-admission malnutrition and sarcopenia. There was neither significant difference in the proportion of patients with malnutrition at admission among different age groups ( P=0.438), nor in that at discharge among different age groups ( P=0.439). The proportion of patients with malnutrition showed no significant difference between subgroups with patients<65 years old and ≥ 65 years old, at admission and discharge ( P>0.05). However, comparison of the proportion of patients with sarcopenia between subgroups with patients<65 years old and ≥65 years old displayed significant differences at admission and discharge ( P<0.001), but not the comparison of the proportion of patients with possible sarcopenia ( P>0.05). The length of hospital stay in patients with malnutrition was significantly longer than that in patients without malnutrition [(13.22±6.24) days vs. (12.08±5.25) days, P<0.001]. The length of hospital stay of patients with and without sarcopenia was also significantly different [(12.87±5.93) days vs. (12.02±5.22) days, P<0.001). Patients with concurrent malnutrition and sarcopenia had longer hospital stay [(14.57±7.15) days vs. (12.07±5.22) days, P<0.001], and higher medical cost [(2.78±2.19) ten thousand Chinese Yuan vs. (2.24±2.33) ten thousand Chinese Yuan, P<0.05)] compared with those without concurrent malnutrition and sarcopenia. Conclusions:A large proportion of patients with digestive disorders were diagnosed with malnutrition and/or possible sarcopenia during hospitalization. There is possible correlation between malnutrition and possible sarcopenia, and both can lead to a longer hospital stay and higher medical cost.
