Current nutritional status assessment tools for metabolic care and clinical nutrition

Implementation of an Evidence-Based Nursing Protocol for Mechanical Complications of Enteral Nutrition: A Randomized Controlled Trial

BACKGROUND

Patients admitted to the intensive care unit (ICU) are at risk for malnutrition. To provide sufficient nutritional support, enteral nutrition (EN) is the preferred method for patients admitted to the neurology ICU.

PURPOSE

The purpose of this study was to examine the clinical effectiveness of an evidence-based nursing protocol for preventing and managing mechanical complications of EN for patients admitted to the neurology ICU.

METHODS

A randomized controlled trial design was used. The control group received general care, and the test group received care per the evidence-based nursing protocol.

RESULTS

A total of 118 patients participated in the study (59 each in the control and test group). The test group showed improved nutritional status measured by the Nutrition Risk Screening 2002 score, lower acute gastrointestinal injury grading, improved serum nutritional indicators, and less mechanical complications.

CONCLUSION

Implementing an evidence-based nursing protocol was feasible and led to positive patient outcomes.

Nutritional Assessment and Management of Patients with Brain Neoplasms Undergoing Neurosurgery: A Systematic Review

BACKGROUND/AIM

Nutritional management in neurosurgical patients with brain neoplasms is critical, as optimal nutritional status is potentially associated with improved clinical outcomes. This systematic review aimed to analyze the impact of pre- and postoperative nutritional assessment and effect of prepost interventions on the clinical outcomes.

METHODS

A systematic review was conducted using the PubMed, Cochrane Library, Embase, and CINAHL databases, complemented by a search of grey literature. Study quality was assessed using the Joanna Briggs Institute framework, and the certainty of evidence was graded according to the Oxford Centre for Evidence-Based Medicine levels.

RESULTS

Fourteen studies, encompassing a total of 11,224 adult patients with brain neoplasms, were included. Many of these studies were retrospective, had small sample sizes, and examined diverse nutritional protocols. Preoperative nutritional status assessment, including clinical parameters such as albumin (p < 0.001), Controlling Nutritional Status score (p = 0.001), and Prognostic Nutritional Index (p < 0.010), combined with postoperative oral nutritional supplements (p < 0.001), was significantly associated with postoperative clinical outcomes. Additionally, personalized nutritional counseling contributed to a reduction in complications and facilitated more effective functional recovery.

CONCLUSIONS

Nutritional care is vital in managing neurosurgical patients with brain neoplasms, reducing complications and enhancing postoperative recovery and overall clinical outcomes. A multidisciplinary team is key to optimal outcomes. Future research should aim to standardize protocols for broader applicability.

Impact of prognostic nutritional index on mortality among patients receiving coronary artery bypass grafting surgery: a retrospective cohort study

BACKGROUND

The Prognostic Nutritional Index (PNI), calculated from serum albumin levels and lymphocyte counts, is a simple and objective measure of nutritional status. While PNI has been shown to be a significant prognostic tool in gastrointestinal surgery and heart failure, its role in patients undergoing coronary artery bypass grafting (CABG) remains unclear. This study aims to evaluate whether PNI can serve as a meaningful risk factor for patients undergoing CABG.

METHODS

This observational retrospective analysis involved a substantial sample of 2889 patients who underwent isolated CABG at one of four medical centres. The primary outcomes included short- and long-term mortality. Perioperative serum albumin levels and total lymphocyte counts used to calculate PNIs were collected 48 hours before the operation, 24 hours after the operation and at discharge. Univariate and multivariate logistic regression analyses were conducted to identify the risk factors of short-term mortality. Survival and relative risks were assessed using Cox regression analysis and the Kaplan-Meier test.

RESULTS

Among the 2889 patients, 64 (2.2%) died within 30 days following CABG. Multivariate logistic regression revealed that higher preoperative PNI was independently associated with reduced short-term mortality (OR=0.852 per unit increase, 95% CI 0.802 to 0.904, p<0.001). Regarding long-term outcomes, among the 2825 patients who were discharged alive, 199 deaths occurred over a median follow-up period of 54.9 months. Patients with a normal PNI at discharge (>40) exhibited significantly higher long-term survival rates compared with those with a lower PNI (≤40) (log-rank p=0.003). Multivariate Cox regression analysis confirmed that a normal PNI at discharge(>40) independently predicted a lower risk of long-term all-cause mortality (HR=0.718, 95% CI 0.529 to 0.974, p=0.033).

CONCLUSIONS

PNI at various time points may play a crucial predictive role in mortality among CABG-treated patients, and a low PNI serves as a risk factor for both short- and long-term survival.

Associations of Life's Essential 8 with low muscle mass mediated by testosterone, inflammation, and nutritional status in United States adults: a cross-sectional study

BACKGROUND

Low muscle mass, defined as appendicular lean mass adjusted for body mass index (BMI), may indicate early skeletal muscle deterioration.

OBJECTIVES

This study aimed to investigate the relationship between Life's Essential 8 (LE8), the updated cardiovascular health (CVH) metrics by the American Heart Association, and low muscle mass, including the impact of related biomarkers on muscle quality.

METHODS

This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (NHANES) cycles 2011-2014, selected due to their inclusion of the most recent appendicular lean mass measurements available in the NHANES dataset. Participants aged 20-60 y were included. We employed weighted logistic regression models, restrictive cubic splines, and weighted quantile sum (WQS) regression to assess the relationship between LE8 scores and low muscle mass. Four mediation models were constructed to explore whether serum testosterone in males, serum sex hormone-binding globulin (SHBG) in females, serum albumin, and systemic immune-inflammation index (SII) mediated the association between LE8 scores and low muscle mass.

RESULTS

Higher LE8 scores are associated with lower odds of low muscle mass. Compared with participants with low CVH, those with intermediate and high CVH had 49% (odds ratio [OR]: 0.51, 95% confidence interval [CI]: 0.30, 0.87) and 86% (OR 0.14, 95% CI: 0.06, 0.29) lower odds of low muscle mass, respectively. Mediation analysis revealed that testosterone, SHBG, SII, and albumin partially mediated the association between LE8 scores and low muscle mass. The WQS regression model indicated that BMI and physical activity might be important factors influencing low muscle mass within the components of LE8.

CONCLUSIONS

LE8 scores negatively associated with low muscle mass in United States adults. Serum testosterone in males and SHBG in females were negative predictors of low muscle mass, whereas SII was inversely associated. Serum albumin had a beneficial effect on muscle mass.

Predictive Feasibility of the Graz Malnutrition Screening, Controlling Nutritional Status Score, Geriatric Nutritional Risk Index, and Prognostic Nutritional Index for Postoperative Long-Term Mortality After Surgically Treated Proximal Femur Fracture

BACKGROUND

Hip fractures are a prevalent and serious health issue, particularly among the elderly population aged >65 years. These injuries are associated with elevated rates of postoperative complications and mortality, significantly diminishing patients' quality of life in both the short- and long-term. The prognosis for recovery is further exacerbated in individuals with signs of malnutrition. The primary objective of this study was to evaluate the predictive value of four distinct nutritional assessment scores in relation to postoperative mortality in patients undergoing surgical intervention for hip fractures at 1, 3, 6, 12, and 24 months.

METHODS

This observational study included patients admitted to the Department of Traumatology at the Medical University for the surgical management of hip fractures between January 2019 and November 2021. Nutritional assessment scores were derived from a retrospective analysis of clinical data. The statistical correlation between nutritional scores and postoperative mortality outcomes was rigorously evaluated.

RESULTS

Logistic regression analysis revealed a statistically significant correlation (p < 0.01) between all four nutritional scores and postoperative mortality risk. The malnourished cohorts demonstrated a markedly higher risk of mortality compared to those with adequate nutritional status, as indicated by the following risk ratios: Graz Malnutrition Screening (risk ratio = 2.53-1.68), Prognostic Nutritional Index (risk ratio = 2.44-1.74), Geriatric Nutritional Risk Index (risk ratio = 2.05-1.58), and Controlling Nutritional Status (risk ratio = 2.34-1.46). Despite these findings, the receiver operating characteristic analysis yielded area under the curve (AUC) values ranging from 0.64 to 0.68, indicating limited predictive power.

CONCLUSIONS

Although a significant correlation existed between the evaluated nutritional scores and postoperative mortality, the predictive value of these scores was quantitatively low. No single nutritional assessment tool has emerged as a strong predictor of postoperative outcomes in this patient population. Consequently, implementation of any specific nutritional screening tool for standard assessment in patients with hip fractures is not recommended at this time. Nevertheless, given the established association between malnutrition and postoperative mortality, a comprehensive evaluation of nutritional status is advisable and further research is needed.

Application of NRS2002 and PG-SGA in nutritional assessment for perioperative patients with head and neck squamous cell carcinoma: An observational study

This study aimed to compare the effectiveness of 2 nutritional assessment tools, the Nutritional Risk Screening Scale 2002 (NRS2002) and the Patient-Generated Subjective Global Assessment (PG-SGA), for evaluating the nutritional status of perioperative head and neck squamous cell carcinoma (HNSCC) patients, to facilitate early nutritional interventions and improve clinical outcomes. An observational, comparative study was conducted at the Zhejiang Cancer Hospital, recruiting patients diagnosed with HNSCC scheduled for surgical treatment. The NRS2002 and PG-SGA were applied to assess patients' nutritional risk at multiple time points: upon admission, the day before surgery, 2 days after surgery, a week after surgery, and at discharge. Statistical analyses were performed using McNemar and Kappa tests to assess differences and consistency between NRS2002 and PG-SGA. A total of 209 patients were included in this study, predominantly male, with an average age of 60 years. Nutritional risk assessments identified an inverted "V" trend in nutritional risk, with the peak occurring 2 days post-surgery. PG-SGA consistently showed a higher screening positivity rate compared to NRS2002. The receiver operating characteristic curve analysis highlighted the discriminative power of both tools, with PG-SGA and NRS2002 showing high area under the curve values. Both NRS2002 and PG-SGA are effective for nutritional screening in HNSCC patients, with PG-SGA demonstrating a slightly higher sensitivity before surgery. PG-SGA may be more suitable for preoperative application, whereas NRS2002 is more appropriate for postoperative use.

Investigation of nutrition status and analysis of 180-day readmission factors in elderly hospitalized patients with COPD

BACKGROUND AND OBJECTIVE

Malnutrition is prevalent among elderly patients with COPD, who also experience a high rate of readmission. Therefore, it is imperative to investigate the nutrition status of these patients, identify risk factors for readmission, and offer insights for clinical management. To achieve this, a cross-sectional study was conducted to investigate factors influencing nutrition status using GLIM criteria and explore the 180-day readmission factors among hospitalized elderly COPD patients.

METHORDS AND RESULTS

The data were collected from a hospital in Southwest China, encompassing a cohort of 319 eligible patients. Among elderly hospitalized COPD patients, the prevalence of malnutrition was 49.53% (158/319). Multivariate logistic regression revealed malnutrition (OR = 3.184), very severe airway obstruction (OR = 3.735), and Number of comorbidities ≥ 3 (OR = 5.754) as significant risk factors for 180-day readmission.

CONCLUSIONS

These findings suggest that malnutrition is a prevalent issue among elderly hospitalized patients with COPD and constitutes one of the risk factors contributing to the 180-day readmission rate. Therefore, timely identification and treatment for malnourished patients are crucial.

Predictive value of the geriatric nutrition risk index for postoperative delirium in elderly patients undergoing cardiac surgery

AIMS

The aims of the study were to determine the relationship between preoperative geriatric nutritional risk index (GNRI) and the occurrence of postoperative delirium (POD) in elderly patients after cardiac surgery and to evaluate the additive value of GNRI for predicting POD.

METHODS

The data were extracted from the Multiparameter Intelligent Monitoring in Intensive Care (MIMIC-IV) database. Patients who underwent cardiac surgery and were aged 65 or older were included. The relationship between preoperative GNRI and POD was investigated using logistic regression. We determined the added predictive value of preoperative GNRI for POD by measuring the changes in the area under the receiver operating characteristic curve (AUC) and calculating the net reclassification improvement (NRI) and integrated discrimination improvement (IDI).

RESULTS

A total of 4286 patients were included in the study, and 659 (16.1%) developed POD. Patients with POD had significantly lower GNRI scores than patients without POD (median 111.1 vs. 113.4, p < 0.001). Malnourished patients (GNRI ≤ 98) had a significantly higher risk of POD (odds ratio, 1.83, 90% CI, 1.42-2.34, p < 0.001) than those without malnutrition (GNRI > 98). This correlation remains after adjusting for confounding variables. The addition of GNRI to the multivariable models slightly but not significantly increases the AUCs (all p > 0.05). Incorporating GNRI increases NRIs in some models and IDIs in all models (all p < 0.05).

CONCLUSIONS

Our results showed a negative association between preoperative GNRI and POD in elderly patients undergoing cardiac surgery. The addition of GNRI to POD prediction models may improve their predictive accuracy. However, these findings were based on a single-center cohort and will need to be validated in future studies involving multiple centers.

Exploring the Spectrum of VEGF Inhibitors' Toxicities from Systemic to Intra-Vitreal Usage in Medical Practice

The use of Vascular Endothelial Growth Factor inhibitors (VEGFi) has become prevalent in the field of medicine, given the high incidence of various pathological conditions necessitating VEGF inhibition within the general population. These conditions encompass a range of advanced neoplasms, such as colorectal cancer, non-small cell lung cancer, renal cancer, ovarian cancer, and others, along with ocular diseases. The utilization of VEGFi is not without potential risks and adverse effects, requiring healthcare providers to be well-prepared for identification and management. VEGFi can be broadly categorized into two groups: antibodies or chimeric proteins that specifically target VEGF (bevacizumab, ramucirumab, aflibercept, ranibizumab, and brolucizumab) and non-selective and selective small molecules (sunitinib, sorafenib, cabozantinib, lenvatinib, regorafenib, etc.) designed to impede intracellular signaling of the VEGF receptor (RTKi, receptor tyrosine kinase inhibitors). The presentation and mechanisms of adverse effects resulting from VEGFi depend primarily on this distinction and the route of drug administration (systemic or intra-vitreal). This review provides a thorough examination of the causes, recognition, management, and preventive strategies for VEGFi toxicities with the goal of offering support to oncologists in both clinical practice and the design of clinical trials.

Clusters of Body Fat and Nutritional Parameters are Strongly Associated with Diabetic Kidney Disease in Adults with Type 2 Diabetes

INTRODUCTION

Diabetic kidney disease (DKD) has become the leading cause of chronic kidney disease and end-stage renal failure in most developed and many developing countries. Strategies aimed at identifying potential modifiable risk factors for DKD are urgently needed. Here, we investigated the association between clusters of body fat and nutritional parameters with DKD in adults with type 2 diabetes mellitus (T2DM).

METHODS

This was a cross-sectional study of 184 participants with T2DM. Biochemical parameters including fasting blood glucose, hemoglobin A1c, hemoglobin, albumin, creatinine, and urinary albumin-to-creatinine ratio (UACR) were measured. The data for percentage of body fat mass (PBF), visceral fat area (VFA), phase angle at 50 kHz (PA50), and body cell mass (BCM) were obtained by bioelectrical impedance analysis (BIA). DKD was diagnosed by UACR and estimated glomerular filtration rate. Factor analysis was used for dimensionality reduction clustering among variables. The association of clusters with the presence of DKD was assessed using binary logistic regression analysis.

RESULTS

Factor analysis identified two clusters which were interpreted as a body fat cluster with positive loadings of VFA, body mass index, waist circumstance, and PBF and a nutritional parameters cluster with positive loadings of PA50, hemoglobin, BCM, and albumin. Participants were divided into the four groups based on the sex-specific cutoff value (median) of each cluster score calculated using the cluster weights and the original variable values. Only participants with high body fat and poor nutritional parameters (OR 3.43, 95% CI 1.25-9.42) were associated with increased odds of having DKD.

CONCLUSION

Body fat and nutritional parameters were strongly associated with and considerably contributed to the presence of DKD, suggesting that body fat and nutrition might be promising markers representing metabolic state in pathogenesis of DKD and clinical utility of BIA might provide valuable recommendations to patients with T2DM.

Dyslipidemia and Nutritional Status of HIV-Infected Children and Adolescents on Antiretroviral Treatment at the Comprehensive Chronic Care and Training Center of Jimma Medical Center

Background

Highly active antiretroviral treatment is beneficial to suppress human immune virus replication in infected individuals. However, dyslipidemia and other metabolic abnormalities have emerged due to antiretroviral treatment. The prevalence of dyslipidemia in children and adolescents on antiretroviral treatment varies from 20% to 70%. The lack of data on children and adolescents in Ethiopia was the rationale for conducting this study. We aimed to determine prevalence of dyslipidemia and nutritional status in children and adolescents on follow-up at Jimma medical center.

Materials and Methods

A hospital-based cross-sectional study was conducted with 150 children and adolescents on follow-up at Jimma medical center. A systematic sampling technique was employed. An interview was carried out to collect socioeconomic and demographic data and a review of medical records was carried out to collect patients' clinical data. Anthropometric data were computed using the CDC growth chart. About 3-5mL of fasting blood was collected to measure lipid profile. Multivariable logistic regression was performed to find the association between risk factors and lipid profile.

Results

The overall prevalence of dyslipidemia in this study was 72%. About 72% and 21.3% of study subjects had low high-density lipoprotein and high triglyceride, respectively. Significant associations were observed between BMI for age ≤5% (AOR: 2.02, 95% CI: 1.14-3.66; P=0.015) and low high-density lipoprotein; greater than 150 months on treatment (AOR: 1.02, 95% CI: 1.00-1.03; P=0.01) and high triglyceride; and BMI for age ≤5% (AOR: 1.86, 95% CI: 1.03-1.37; P=0.04) and high triglyceride.

Conclusion

BMI for age <5%, treatment duration of greater than 150 months, and parents' educational level were significantly associated with dyslipidemia, so it is recommended that monitoring of those variables will help to reduce dyslipidemia and its complications in children and adolescents receiving treatment.

Prevalence of chronic periodontitis in patients undergoing peritoneal dialysis and its correlation with peritoneal dialysis-related complications

OBJECTIVE

The microinflammatory state can influence the occurrence of dialysis-related complications in dialysis patients. Chronic periodontitis (CP), in which plaque biofilm is considered to be the initiating factor, is a chronic infectious disease in the oral cavity. It is still uncertain whether CP affects the microinflammatory state in peritoneal dialysis (PD) and the occurrence of dialysis-related complications. The purpose of this study was to investigate the correlation between the periodontal index and clinical parameters in peritoneal dialysis patients with CP and dialysis-related complications, including peritoneal dialysis-associated peritonitis (PDAP) and cardiovascular and cerebrovascular events (CCEs).

METHODS

This was a retrospective cohort study, and 76 patients undergoing PD were enrolled. Clinical parameters, the occurrence of PD-related complications and periodontitis-related indicators, including the gingival index (GI), plaque index (PLI), probing depth (PPD) and clinical attachment loss (CAL), were collected. Correlation analysis was used to explore the correlation between periodontal or clinical parameters and the occurrence of PD-related complications.

RESULTS

All the patients had different degrees of periodontitis (mild 9.2%, moderate 72.4%, severe 18.4%); PPD was inversely related to serum albumin (r = - 0.235, p = 0.041); CAL has a positive correlation with serum C-reactive protein (rs = 0.242, p = 0.035); PLI was positively correlated with serum calcium (r = 0.314, p = 0.006). ANOVA, multivariate logistic regression analysis and Kaplan-Meier Survival curve suggested that CAL was a risk factor for the occurrence of PDAP. There was no correlation between periodontal parameters and CCEs or poor prognosis.

CONCLUSION

CP is universally present in PD patients, and the presentation of periodontitis influences the systemic inflammatory state in PD patients. CP is a risk factor for PDAP.

Nursing Practice Based on Evidence-Based Concepts to Prevent Enteral Nutrition Complications for Critically Ill Neurosurgical Patients

Purpose

To explore the practical value of enteral nutrition care guided by evidence-based concepts in preventing enteral nutritional complications in critically ill neurosurgical patients.

Methods

Three hundred critically ill patients from March 2020 to October 2021 from our neurosurgery department were included in the study. Patients were divided into a control group (March to December 2020, n = 150) and a study group (January to October 2021, n = 150) according to the order of their admission. The control group received conventional enteral nutrition care, and the study group received enteral nutrition care based on evidence-based concept guidance. The levels of serum nutritional indicators [hemoglobin (Hb), albumin (ALB), and total protein (TP)], feeding compliance rate, the incidence of complications (gastric retention, bloating, diarrhea, reflux, vomiting, aspiration, stress ulcers, etc.), and prognosis during the observation period were compared between the two groups. The scores of the questionnaire of knowledge, attitude, and practice on nutrition among neurosurgical nurses before and after the implementation of evidence-based care were compared among nursing staff in the study group.

Results

At 1 and 2 weeks after enrollment, Hb, ALB, and TP levels were lower in both groups than before enrollment in the same group (P < 0.05). At 2 weeks after enrollment, Hb, ALB, and TP levels were higher in both groups than at 1 week after enrollment in the same group (P < 0.05). At 1 and 2 weeks after enrollment, Hb, ALB, and TP levels were higher in the study group than in the control group (P < 0.05). At 7 days after feeding, the feeding compliance rate was higher in the study group (94.67%) than in the control group (70.00%) (P < 0.05). The total complication rate was lower in the study group (8.00%) than in the control group (16.00%) (P < 0.05). The percentage of good prognosis was higher in the study group (34.00%) than in the control group (23.33%) (P < 0.05). After the implementation of evidence-based care, caregivers in the study group scored higher on nutrition knowledge, nutrition attitudes, and nutrition practices than those before the implementation (P < 0.05).

Conclusion

The implementation of evidence-based nursing interventions in critically ill neurosurgical patients based on evidence-based concepts is of great clinical value in correcting their nutritional status, preventing enteral nutritional complications, improving prognosis, and enhancing the nutritional knowledge, attitudes, and practices of nursing staff.

Interactions of Comorbidity and Five Simple Environmental Unhealthy Habits Concerning Physical and Mental Quality of Life in the Clinical Setting

The objective of this study was to examine the interactions between comorbidity and five lifestyle single habits concerning different subscales of quality of life (QoL). For the study, 302 patients were consecutively recruited at the internal medicine department of a tertiary teaching hospital. Lifestyle habits, comorbidities and QoL were recorded according to validated questionnaires. Five single unhealthy habits, such as tobacco consumption, dietary intake of ultra-processed pastries, raw nuts or carbonated drinks, sleep time and physical activity patterns were selected according to previously published data. The main outcomes of the study were the scores of the eight subscales of the SF-36 QoL survey. The aggregate of unhealthy habits showed statistically significant association to every category in the SF-36 questionnaire, both in the univariate and the multivariate analysis when adjusting by age, sex and comorbidity. An interaction was found between comorbidity and unhealthy habits in both physical and mental summaries of SF-36. In conclusion, the lifestyle assessment according to five unhealthy habits is associated with a worse QoL. The interaction between comorbidity and unhealthy habits is especially clear in diseased patients due to the interplay between illness and lifestyle in the prediction of QoL.

Comparison of Two Malnutrition Assessment Scales in Predicting Postoperative Complications in Elderly Patients Undergoing Noncardiac Surgery

Background: The present study was designed to investigate the relationship between two malnutrition assessment scales, perioperative nutrition screen (PONS) and Nutritional Risk Screening 2002 (NRS2002), with postoperative complications in elderly patients after noncardiac surgery.

Methods: This was a secondary analysis of a prospective cohort study. Elderly patients (65–90 years) undergoing noncardiac surgery were enrolled in Peking University First Hospital. Malnutrition was screened by PONS and NRS2002 at the day before surgery. Multivariable analysis was employed to analyze the relationship between PONS and NRS2002 and postoperative 30-day complications. Receiver operating characteristic (ROC) curve was generated to evaluate the predictive value of PONS and NRS2002 in predicting postoperative complications.

Results: A total of 915 patients with mean age of 71.6 ± 5.2 years were consecutively enrolled from September 21, 2017, to April 10, 2019. The incidence of malnutrition was 27.3% (250/915) by PONS ≥ 1 and 53.6% (490/915) by NRS2002 ≥ 3. The overall incidence of complications within postoperative 30 days was 45.8% (419/915). After confounders were adjusted, malnutrition by PONS ≥ 1 (OR 2.308, 95% CI 1.676–3.178, P < 0.001), but not NRS2002 ≥ 3 (OR 1.313, 95% CI 0.973–1.771, P = 0.075), was related with an increased risk of postoperative complications. ROC curve analysis showed that the performances of PONS [area under the ROC curve (AUC) 0.595, 95% CI 0.558–0.633] showed very weak improvement in predicting postoperative complications than NRS2002 score (AUC 0.577, 95% CI 0.540–0.614).

Conclusion: The present study found that malnutrition diagnosed by PONS was related with an increased risk of postoperative complications. The performances of PONS and NRS2002 were poor in predicting overall postoperative complications.
