High Controlling Nutritional Status Score Research Articles

Predictive values of four nutritional indices for adverse outcomes in patients with hypertension.

Malnutrition, evaluated by nutritional indices, is reportedly related to a poor prognosis in patients with hypertension. However, clinical evidence on which index is more suitable for predicting a kidney prognosis is limited, and it has not been evaluated in hypertension. The aim of the present study was to investigate and compare the predictive values of four nutritional indices: Geriatric Nutritional Risk Index (GNRI); Prognostic Nutrition Index (PNI); Triglycerides × Total cholesterol × Body weight Index (TCBI); and the controlling nutritional status (CONUT) score. A retrospective, cohort study of 1255 hypertensive patients under care in the Fukushima Cohort Study was conducted. The primary outcome was kidney events, defined as a combination of a 50% decline in eGFR from baseline and renal failure requiring dialysis therapy or kidney transplantation. Kaplan-Meier analyses and multivariate Cox regression analyses were conducted to examine associations between the four nutritional indices and kidney events. The area under the curve (AUC) values of the receiver-operating characteristic curves were also examined to compare the predictive values of these nutritional indices. Lower GNRI, lower PNI, and higher CONUT score were significantly related to a higher risk of kidney events. GNRI (AUC = 0.729, 95% confidence interval 0.681-0.777) and PNI (AUC = 0.710, 95% confidence interval 0.665-0.756) had significantly higher AUCs for kidney events than the TCBI and CONUT score. GNRI and PNI showed greater predictive values for kidney events than other nutritional indices in patients with hypertension.

Controlling Nutritional Status (CONUT) Score: a new tool for characterization and prognosis of patients with infective endocarditis

Abstract Background malnutrition is a marker of unfavorable prognosis in different medical conditions, however, the association between new objective immunonutritional indexes and outcomes for patients with infective endocarditis (IE) is not fully studied. Purpose the aim of this study was to assess the role of the Controlling Nutritional Status (CONUT) Score in the characterization of patients with IE and its association with prognostic outcomes. Methods a total of 184 cases of confirmed IE were consecutively collected and followed during one year after diagnosis in two tertiary hospitals. CONUT score was calculated using serum albumin, total cholesterol and lymphocyte count [(range 0-12), the higher, the worse] at diagnosis, and patients were categorised as CONUT-high (>=6, n=98), and CONUT-low (<6, n=86) based on the sample median value. Results mean age was 70 [SD 15] years, 64% were men and community-acquired infections were 69%. Median score value was 6 (4). As shown in Table 1 and 2, diabetes and frailty were more prevalent in CONUT-high group, who showed a worse profile of nutritional biomarkers. Overall, the most frequent pathogen was S. viridans (n=43). By groups, S. aureus was predominantly isolated in CONUT-high (20 vs 8%; p 0.02), and non-viridans streptococci in CONUT-low (9 vs 2%, p 0.03). Regarding infection site, IE of aortic bioprostheses was more common in CONUT-high, whereas mechanical aortic valves and mitral bioprostheses were more frequently involved in CONUT-low. Larger vegetations [14 (11) vs 11 (7) mm, p 0.02], and more periannular abscesses (25 vs 13%, p 0.04) were detected in CONUT-high, who presented more acute kidney injury and septic shock during hospitalization. Despite higher predicted surgical risk in CONUT-high, neither the proportion of patients who underwent surgery nor in-hospital mortality, differed between groups. When analyzing according to the therapeutic approach, only among those medically managed patients without surgical indication, in-hospital mortality was higher in CONUT-high. At 1-year follow-up, rehospitalization rate tended to be lower in those with a better nutritional status (35% vs 51%, p 0.07). Conclusions in patients with IE and a high CONUT score, diabetes and frailty were more prevalent. In addition, virulent pathogens, larger vegetations and periannular complications were more frequently reported. Although surgery performance and in-hospital mortality did not differ between groups, a worse nutritional status was associated with a higher rate of clinical complications and higher mortality among patients with conservative management who did not meet surgical criteria.

The Added Value of Controlling Nutritional Status (Conut) Score for Preoperative Counselling on Significant Early Loss of Renal Function After Radical Nephrectomy for Renal Cell Carcinoma

Background and Objectives: We aimed at evaluating the impact of Controlling Nutritional Status (CONUT) score on clinically significant decline in estimated glomerular filtration rate (eGFR) in patients with non-metastatic Clear Cell Renal Cell Carcinoma (ccRCC) undergoing radical nephrectomy (RN). Materials and methods: We retrospectively analyzed a multi-institutional cohort of 140 patients with ccRCC who underwent RN between 2016 and 2018 at three Urological Centers. The CONUT score was calculated with an algorithm including serum albumin, total lymphocyte count, and cholesterol. Clinical and pathologic features were analyzed using Fisher’s exact test for categorical variables and a Mann–Whitney U test for continuous variables. To define the independent predictors of clinically significant eGFR decline, univariable (UVA) and multivariable (MVA) binomial logistic regression analyses were performed in order to assess the Odds Ratio (OR) with 95% Confidence Intervals (CIs). Results: The optimal cut-off value to discriminate between a low and high CONUT score was assessed by calculating the ROC curve. The area under the curve (AUC) was 0.67 (95%CI 0.59–0.78) with the most appropriate cut-off value at 2 points. Overall, 46 patients (32.9%) had a high CONUT score (>2). Statistically significant variables associated with eGFR decline at 24 months were age ≥ 70 (OR 2.01; 95%CI 1.17–3.09; p 0.05), stage II–III chronic kidney disease (CKD) (OR 6.05; 95%CI 1.79–28.3; p 0.001), and a high CONUT score (OR 3.98; 95%CI 1.58–10.4; p 0.004). Conclusions: The CONUT score is a low-time-consuming, cost-effective, and promising tool able to preoperatively screen patients at risk of developing CKD after a RN.

Global Leadership Initiative on Malnutrition Criteria and Immunonutritional Status Predict Chemoadherence and Survival in Stage II/III Gastric Cancer Treated with XELOX Chemotherapy.

Adjuvant chemotherapy is crucial for the treatment of advanced gastric cancer. However, various factors negatively impact chemoadherence, with malnutrition after gastrectomy being a critical determinant. This study aims to analyze the impact of malnutrition, assessed through the Global Leadership Initiative on Malnutrition (GLIM) and other immunonutritional indices, on chemoadherence and its subsequent effect on survival. This retrospective study included 116 patients who underwent curative gastrectomy and received oxaliplatin and capecitabine (XELOX). Preoperative nutritional status was assessed using the GLIM criteria along with other immunonutritional indices, such as the prognostic nutritional index (PNI), C-reactive protein-to-albumin ratio (CAR), neutrophil-lymphocyte ratio (NLR), controlling nutritional status (CONUT) score, and modified Glasgow Prognostic Score (mGPS). Chemotherapy adherence was measured using relative dose intensity (RDI). Statistical analyses included least absolute shrinkage and selection operator (LASSO) regression to identify the key predictors of RDI and Cox proportional hazards models and assess the impact on survival. Overall, 116 patients were included in this analysis. In the multivariate analysis using LASSO regression, higher GLIM severity was independently associated with a lower RDI (coefficient = -0.0216; p < 0.01). Other significant factors influencing RDI included older age (p < 0.01), female sex (p = 0.02), higher mGPS (p = 0.03), higher CONUT score (p = 0.04), and higher CAR (p = 0.05), all of which were associated with a lower RDI. The Cox proportional hazards analysis revealed that higher RDI was significantly associated with better survival (hazard ratio [HR] = 0.06; p < 0.005). This study highlights the critical role of immunonutritional status, particularly as measured using the GLIM criteria, in maintaining adherence to chemotherapy and improving survival outcomes in patients with gastric cancer. Routine preoperative nutritional assessments using GLIM can help identify high-risk patients, and early nutritional interventions may improve chemotherapy adherence and outcomes. These findings support the integration of nutritional strategies, specifically targeting those identified by the GLIM, into standard care to enhance the efficacy and survival of chemotherapy.

The Controlling Nutritional Status (CONUT) Score as a Predictor of Local Recurrence in Patients Underwent Partial Nephrectomy Alongside the R.E.N.A.L. Nephrometry Score.

This study aims to assess the utility of the CONUT (Controlling Nutritional Status) Score and R.E.N.A.L. (Renal Nephrometry Score) Score in predicting tumor recurrence in patients with kidney cancer. Additionally, we investigated which parameters contributed to these scores. In total, 115 patients who underwent partial nephrectomy between January 2015 and August 2023 at a single tertiary center were enrolled. After the exclusion criteria, data from 88 patients were analyzed. Age, gender, body mass index (BMI), comorbidities (hypertension, diabetes), smoking status, tumor characteristics, CONUT Scores, and R.E.N.A.L. scores were retrospectively recorded. Statistical analyses were performed, and significant p was p < 0.05. The presence of diabetes and hypertension showed a statistically significant association with tumor recurrence (p = 0.033 and p = 0.003, respectively). A high BMI significantly increased the risk of recurrence (p < 0.05). There was a strong positive relationship between the high tumor stage and positive surgical margins with recurrence (p < 0.001). Patients with high R.E.N.A.L. Scores and high CONUT Scores had a higher risk of recurrence (42.1% and 8.7%, respectively), and this difference was statistically significant (p < 0.001). CONUT and R.E.N.A.L. scores may be used to predict tumor recurrence after partial nephrectomy. Additionally, diabetes, hypertension, high BMI, and positive surgical margin rate might affect surgical success rate for recurrences. Clinicians should consider all these parameters and coring systems to gather more successful results after partial nephrectomy.

Can CONUT and PNI Scores Predict Necrotizing Pancreatitis in Acute Pancreatitis Patients Presenting to the Emergency Department?

Background and Objectives: Acute pancreatitis, characterized by pancreatic inflammation, poses significant morbidity and mortality worldwide, with varied etiologies including gallstones, alcohol, and certain medications. Necrotizing pancreatitis represents a severe form of parenchymal damage with considerable impact on patient quality of life. Early identification of necrotizing pancreatitis is crucial for timely intervention and improved outcomes. The aim of this study was to investigate the usability of CONUT and PNI scores as prognostic indicators. Materials and Methods: We conducted a retrospective observational study involving patients presenting to the emergency department with acute pancreatitis between January 2020 and October 2023. The Controlling Nutritional Status (CONUT) score and Prognostic Nutrition Index (PNI) were calculated from serum biomarkers to assess nutritional status. Patients were categorized into necrotizing and nonnecrotizing pancreatitis groups, and the utility of CONUT and PNI scores in predicting necrotizing pancreatitis was evaluated. Results: A total of 339 patients were included, with 8.26% diagnosed with necrotizing pancreatitis. CONUT and PNI scores significantly differed between necrotizing and nonnecrotizing groups, with higher CONUT scores and lower PNI scores observed in the necrotizing group. Receiver operating characteristic (ROC) curve analysis revealed significant predictive value of CONUT and PNI scores for necrotizing pancreatitis, with cutoff values of >5 and ≤34, respectively. Conclusions: CONUT and PNI scores demonstrate promise in predicting necrotizing pancreatitis in patients admitted to the emergency department with acute pancreatitis. Additionally, these scores may serve as prognostic indicators for mortality in acute pancreatitis patients. Early identification using CONUT and PNI scores could facilitate timely intervention, potentially reducing mortality and morbidity in this patient population.

Preoperative Serum Albumin and TLC as Predictors of Postoperative Complications in Spine Surgery.

Narrative review. To investigate the state of literature regarding serum albumin and total lymphocyte count and their associations with postoperative complications after spine surgery. Comprehensive search of the PubMed database was performed to find relevant articles addressing preoperative serum albumin, total lymphocyte count, or their respective composite scores and their associations with postoperative complications after spine surgery. Serum albumin level is frequently cited as a marker of patient nutritional status. Total lymphocyte count has more recently gained attention in the literature for similar reasons. Identification of modifiable preoperative patient risk factors for postoperative complications such as malnutrition may help minimize the incidence of postoperative complications. Review of the literature revealed 10 studies that discussed the association between preoperative hypoalbuminemia and postoperative complications. Five studies examined the relationship between either prognostic nutritional index (PNI), controlling nutritional status (CONUT), or both and postoperative complications after spine surgery. Preoperative hypoalbuminemia, low PNI, and high CONUT scores were associated with increased risk of postoperative complications after spine surgery. Preoperative malnourishment is a modifiable patient factor that is associated with an increased risk of postoperative complications after spine surgery.

The controlling nutritional status score as a new prognostic predictor in patients with cervical cancer receiving radiotherapy: a propensity score matching analysis

BackgroundAs assessment tools of nutritional status, the controlling nutritional status (CONUT) and modified controlling nutritional status (mCONUT) score are associated with survival in various cancers. We aimed to investigate the association between the CONUT/mCONUT score’s prognostic value and survival time in patients with FIGO stage IIB–IIIB cervical cancer treated with radiotherapy.MethodsIn this retrospective study, 165 patients between September 2013 and September 2015 were analyzed, and the optimal CONUT/mCONUT score cut-off values were determined using receiver operating characteristic curves. Propensity score matching (PSM) was used to minimize selection bias. The Kaplan–Meier method and a Cox proportional hazard model were used to assess the CONUT/mCONUT score’s predictive value linked to survival time. Two nomograms were created to predict the overall survival (OS) and progression-free survival (PFS).ResultsThe cut-off values for CONUT and mCONUT score were both 2. Five-year OS and PFS rates were higher in a low CONUT score group than in a high CONUT score group (OS: 81.1% vs. 53.8%, respectively, P < 0.001; PFS: 76.4% vs. 48.2%, respectively; P < 0.001). A high CONUT score was associated with decreased OS (hazard ratio (HR) 2.93, 95% CI 1.54–5.56; P = 0.001) and PFS (HR 2.77, 95% CI 1.52–5.04; P < 0.001). High CONUT scores influenced OS in the PSM cohort. A high mCONUT score was not associated with decreased OS and PFS in Cox regression analysis.ConclusionThe CONUT score is a promising indicator for predicting survival in patients with cervical cancer receiving radiotherapy.

Prognostic and clinicopathological value of the controlling nutritional status (CONUT) score in patients with head and neck cancer: a meta-analysis

BackgroundThe efficiency of controlling nutritional status (CONUT) score in detecting the prognosis of head and neck cancer (HNC) patients has been investigated in some works, but no consistent findings are obtained. Therefore, this work focused on evaluating the precise prognostic role of CONUT for HNC patients through meta-analysis.MethodsThe effect of CONUT on predicting the prognosis of HNC patients was evaluated through calculating combined hazard ratios (HRs) as well as 95% confidence intervals (CIs). The correlations of CONUT with clinicopathological features of HNC patients were investigated through combined odds ratios (ORs) and 95%CIs. This study used the random-effects model in the case of significant heterogeneity; or else, we selected the fixed-effects model.ResultsThere were eight articles involving 1,478 patients enrolled for the current meta-analysis. We adopted the fixed-effects model for OS and DFS analysis because of the non-significant heterogeneity. As demonstrated by our combined findings, high CONUT score could significantly predict the poor overall survival (OS) (HR = 1.94, 95%CI = 1.55–2.44, p < 0.001) and disease-free survival (DFS) (HR = 1.93, 95%CI = 1.45–2.56, p < 0.001) of HNC. In addition, higher CONUT score was significantly connected to T3-T4 stage (OR = 3.21, 95%CI = 1.94–5.31, p < 0.001) and N1-N3 stage (OR = 3.10, 95%CI = 1.74–5.53, p < 0.001).ConclusionAccording to findings in the present meta-analysis, high CONUT score significantly predicted the prognosis of OS and DFS for HNC patients. Higher CONUT score was also correlated to larger tumor size and LN metastasis in HNC. Due to it is a cost-effective and easily available parameter, CONUT could serve as promising prognostic biomarker for HNC.

Association of Controlling Nutritional Status Score With Mortality in Patients With Chronic Limb-Threatening Ischemia Following Endovascular Revascularization

Chronic limb-threatening ischemia (CLTI) represents the severest manifestation of peripheral artery disease. Malnutrition is closely associated with poor clinical outcomes in patients with chronic diseases. The Controlling Nutritional Status (CONUT) score is a tool to evaluate the systemic inflammation and nutritional status. This study aimed to investigate the association of baseline CONUT score with mortality in patients with CLTI following endovascular revascularization. A single-center retrospective analysis of patients with CLTI undergoing endovascular revascularization between January 2015 and December 2022 was performed. Preoperative nutritional status was evaluated using CONUT score, which was calculated using the serum albumin concentration, total peripheral lymphocyte count, and total cholesterol concentration. A CONUT score ≥5 indicates moderate or severe malnutrition. The Kaplan-Meier and multivariate Cox proportional hazards regression were used for survival analysis and to evaluate the risk factors associated with mortality. Among 232 enrolled patients, 20.7% of patients had moderate or severe malnutrition defined by the CONUT score. During a median follow-up of 2.1 (interquartile ranges, 1.0-3.5) years, 87 (37.5%) patients died. The 3-year overall survival rate in patients with CLTI who underwent endovascular revascularization was 63.7%. The high CONUT (≥5) group had significantly worse 3-year overall survival (42.0% versus 68.8%, P=0.004) and limb salvage (73.3% versus 84.1%, P=0.005) rates than the low CONUT (<5) group. Multivariate analysis showed that high CONUT score was significantly associated with increased risk for mortality in patients with CLTI after endovascular revascularization (hazard ratio, 1.687; 95% confidence interval, 1.031-2.759; P=0.037). The present study indicated that moderate or severe malnutrition defined by the CONUT score was significantly associated with increased mortality in patients with CLTI following endovascular revascularization. Future study is required to evaluate the efficacy of nutritional intervention in these patients.

Prognostic Value of the Controlling Nutritional Status (CONUT) Score in Patients Who Underwent Cytoreductive Surgery Combined with Hyperthermic Intraperitoneal Chemotherapy.

The Controlling Nutritional Status (CONUT) score is a novel nutritional index that integrates the serum albumin level, peripheral blood lymphocyte count, and total cholesterol level. This retrospective study explores its prognostic significance in patients undergoing cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC). We included 436 patients who underwent CRS-HIPEC, categorized into low (0-3) and high (4-12) CONUT score groups, and performed logistic regression analysis to predict one-year mortality and postoperative morbidity. Our findings revealed that high CONUT scores correlate with increased one-year mortality (47.1% vs. 20.3%, p < 0.001) and morbidity (39.2% vs. 18.2%, p < 0.001) compared to low CONUT scores. Multivariable regression analysis confirmed high CONUT scores as independent predictors of one-year mortality (odds ratio: 2.253, 95% CI: 1.014-5.005, p = 0.046) and postoperative morbidity (odds ratio: 2.201, 95% CI: 1.066-4.547, p = 0.033). These results underscore the CONUT score's effectiveness as an independent marker for evaluating risks associated with CRS-HIPEC, emphasizing its potential to improve risk stratification.

Association between nutrition-related indicators with the risk of chronic obstructive pulmonary disease and all-cause mortality in the elderly population: evidence from NHANES.

This study aims to use six nutrition-related indicators to assess the relationship between nutritional status and the risk of COPD as well as the all-cause mortality rate, and to determine the most reliable predictive indicators. Data from the National Health and Nutrition Examination Survey (NHANES) spanning the years 2013 to 2018 were extracted. Nutritional status was evaluated using Controlling nutritional status (CONUT) score, Geriatric Nutritional Risk Index (GNRI), Advanced Lung Cancer Inflammation Index (ALI), Prognostic Nutritional Index (PNI), Triglycerides (TG) × Total Cholesterol (TC) × Body Weight (BW) Index (TCBI), and Albumin-to-Globulin Ratio (AGR) nutritional-related indicators. Multivariate weighted logistic and Cox regression models were employed to assess the correlation between the six nutritional-related indicators and the risk of COPD and as all-cause mortality. The restricted cubic spline tests were applied to explore potential nonlinear relationships, and ROC curves and C-index analyses were conducted to compare the predictive capabilities of different indicators. Stratified analysis and propensity score matching (PSM) to assess the robustness of the results. In this study, Lower ALI, lower GNRI, and higher CONUT scores were positively correlated with an increased risk of COPD (OR: 1.77, 95% CI: 1.10-2.84) (OR: 8.66, 95% CI: 2.95-25.5), and (OR: 5.11, 95% CI: 1.72-15.2), respectively. It was found that ALI and GNRI had a non-linear relationship with the risk of COPD. After propensity score matching (PSM), the associations between ALI, GNRI, CONUT scores, and COPD remained consistent. Lower ALI, PNI, and GNRI scores were positively associated with all-cause mortality in COPD patients (HR: 2.41, 95% CI: 1.10-5.27), (HR: 3.76, 95% CI: 1.89-7.48), and (HR: 4.55, 95% CI: 1.30-15.9), respectively, with GNRI displaying a non-linear relationship with all-cause mortality. ROC curve and C-index analyses indicated that ALI had the best predictive ability for both COPD risk and all-cause mortality. ALI, GNRI, and CONUT scores are correlated with the risk of COPD, while ALI, PNI, and GNRI scores are associated with all-cause mortality in COPD patients. Compared to other nutritional scores, ALI may provide more effective predictive value for both risk and all-cause mortality.

Nutritional Indices Predict All Cause Mortality in Patients with Multi-/Rifampicin-Drug Resistant Tuberculosis.

Multidrug- and rifampicin-resistant tuberculosis (MDR/RR-TB) with high mortality remains a public health crisis and health security threat. This study aimed to explore the predictive value of nutritional indices for all-cause mortality (ACM) in MDR/RR-TB patients. We retrospectively recruited MDR/RR-TB patients between January 2015 and December 2021, randomly assigning them to training and validation cohorts. Patients were divided into high nutritional risk groups (HNRGs) and low nutritional risk groups (LNRGs) based on the optimal cut-off value obtained from receiver operating characteristic (ROC) analyses of the hemoglobin-albumin-lymphocyte-platelet (HALP) score, prognostic nutritional index (PNI), and controlling nutritional status (CONUT) score. In the training cohort, Kaplan-Meier survival curves and Log rank tests were used to compare overall survival (OS) between the groups. Cox risk proportion regression analyses were used to explore the risk factors of ACM in patients with MDR/RR-TB. The predictive performance of ACM was assessed using area under the curve (AUC), sensitivity and specificity of ROC analyses. A total of 524 MDR/RR-TB patients, with 255 in the training cohort and 269 in the validation cohort, were included. Survival analyses in the training cohort revealed significantly lower OS in the HNRGs compared to the LNRGs. After adjusting for covariates, multivariate analysis identified low HALP score, low PNI and high CONUT score were independent risk factors for ACM in MDR/RR-TB patients. ROC analyses demonstrated good predictive performance for ACM with AUCs of 0.765, 0.783, 0.807, and 0.811 for HALP score, PNI, CONUT score, and their combination, respectively. Similar results were observed in the validation set. HALP score, PNI, and CONUT scores could effectively predict ACM in patients with MDR/RR-TB. Hence, routine screening for malnutrition should be given more attention in clinical practice to identify MDR/RR-TB patients at higher risk of mortality and provide them with nutritional support to reduce mortality.

Predictive value of the controlling nutritional status (CONUT) score to assess long-term mortality (10 Years) in patients with hypertension

Background and aimsMalnutrition is associated with poor outcomes in patients with chronic diseases. The aim of this study is to investigate the prevalence of malnutrition in patients with hypertension and relationship between malnutrition severity and long-term mortality in these patients. Methods and resultsThe study included 11,278 patients with hypertension from the National Health and Nutrition Examination Survey database. The degree of malnutrition was assessed using the Controlled Nutritional Status score, with patients divided into normal, mild, and moderate-to-severe groups. After 10 years of follow-up, the results showed that patients who died had higher CONUT scores, poorer nutritional status, and lower albumin, total cholesterol, and lymphocytes than those who survived (P < 0.05). The Kaplan–Meier analysis revealed that patients with poor nutritional status had a significantly higher risk of all-cause death. In the Non-Lipid Lowering Drugs group, the CONUT score (hazard ratio (HR): 1.225; 95% confidence interval (CI): 1.162–1.292; P < 0.0001), as well as mild (HR: 1.532; 95% CI 1.340–1.751; P < 0.0001) and moderate-to-severe malnutrition (HR: 2.797; 95% CI: 1.441–5.428; P = 0.0024), were independent predictors of long-term mortality. The competing risk regression models showed that cardiovascular and cerebrovascular mortality increased with increasing CONUT scores. The results were robust in both subgroup and sensitivity analyses. ConclusionsMalnutrition significantly impacts long-term mortality in hypertensive patients. The CONUT score may be a useful tool for assessing the nutritional status of patients with hypertension in the non-lipid-lowering population and for predicting their long-term mortality.

The CONUT score is associated with the pathologic grade in non-small cell lung cancer.

Nutritional scores have been reported to be useful prognostic factors for various cancers. This study evaluated the usefulness of the preoperative controlling nutritional status (CONUT) score as a predictor of recurrence of non-small cell lung cancer (NSCLC). The present study included 422 patients with stage I-IIIA NSCLC who underwent complete resection at Tohoku University Hospital between January 2010 and December 2016. The patients were divided into the low-CONUT and high-CONUT groups based on their CONUT scores. Overall survival (OS), recurrence-free survival (RFS), and cumulative recurrence rates in the low- and high-CONUT groups were evaluated retrospectively. One hundred forty-seven patients (34.8%) were assigned to the high-CONUT group. The high-CONUT group had a significantly worse performance status, pleural invasion, vascular invasion, and lung metastasis. In the whole cohort, the low-CONUT group showed better overall survival, recurrence-free survival, and a low cumulative recurrence rate in comparison to the high-CONUT group. There was no significant difference in prognosis or recurrence between the low- and high-CONUT groups after propensity score matching. Patients with a high CONUT score may be at high risk of recurrence because of the high frequency of pleural invasion, vascular invasion, and lung metastasis.

Preoperative Controlling Nutritional Status Score on Predicting the Postoperative Complications Following Major Hepatopancreatobiliary Surgery.

Introduction The prognostic significance of the controlling nutritional status (CONUT) score in hepatopancreatobiliary (HPB) surgery has been shown by many studies but the clinical significance of the CONUT score for postoperative short-term outcomes remains controversial. This study aimed to investigate the impact of the CONUT score on early postoperative outcomes in patients following major HPBsurgery. Method This was a prospective study of 57 patients who underwent major HPB surgery from November 2019 to January 2021 at the Department of Surgical Gastroenterology, Tribhuvan University Teaching Hospital, Nepal. Result A total of 57 patients, 25 males and 32 females, were operated on. The number of patients assigned to the normal, mild, and moderate malnutrition groups was 13, 41, and 3, respectively. The high CONUT group (CONUT ³ 2) consisted of 44 patients (77%) and the low CONUT group (CONUT <2) consisted of 13 patients (33%). The overall complications (Clavien-Dindo classification ³1) and major complications (Clavien-Dindo classification ³3) were present in 37 patients (64.9%) and 14 patients (24.6%), respectively. Increased operative time and intraoperative blood loss were associated with an increased incidence of major (OR: 1.01, p: 0.018) and overall (OR: 1.006, p: 0.039) postoperative complications, respectively, in univariate analysis. A high CONUT score was not associated with a higher incidence of overall and major postoperative complications. Conclusion In our study, the preoperative CONUT score did not predict the postoperative morbidity following hepatopancreatobiliary surgery.

Controlling Nutritional Status (CONUT) Score is Associated with Overall Survival in Patients with Hepatocellular Carcinoma Treated with Conventional Transcatheter Arterial Chemoembolization: A Propensity Score Matched Analysis.

This study aims to evaluate the prognostic value of controlling nutritional status (CONUT) score in determining the prognosis of patients with hepatocellular carcinoma (HCC) treated with conventional transcatheter arterial chemoembolization (cTACE). This study retrospectively analyzed 936 patients who underwent cTACE for HCC between January 2012 and December 2018, and divided them into two groups based on their CONUT score. To balance the bias in baseline characteristics, propensity score matched (PSM) analysis was conducted. The Kaplan-Meier method was used to establish a cumulative survival curve, and the log-rank test was employed to determine differences in overall survival (OS) and progression-free survival (PFS) among the CONUT score groups. Furthermore, the Cox proportional hazard model was employed to assess the correlation between CONUT score and OS and PFS, whereby hazard ratios (HRs) and 95% confidence intervals (95% CIs) were computed. Before PSM, the median OS for the low (≤ 3) and high (≥ 4) CONUT group (558 vs. 378 patients) was 21.7 and 15.6months, respectively, and the median PFS was 5.7 and 5months. Following PSM, both the low and high CONUT score groups comprised 142 patients. The low CONUT score group exhibited a significantly longer OS compared to the high CONUT score group, as determined by the log-rank test (median OS 22.2 vs. 17.0months, P = 0.014). No significant association was observed between CONUT group and PFS (median PFS 6.4 vs. 4.7months, log-rank test, P = 0.121). Cox proportional hazard regression analysis revealed that a CONUT score of ≥ 4 was an independent risk factor for OS in patients with HCC who underwent cTACE (HR = 1.361; 95% CI: 1.047-1.771; P = 0.022). These findings were consistent across most subgroup analyses. A high CONUT score has been found to be a prognostic factor for poorer OS in patients with HCC who underwent cTACE. Level 3, Non-randomized controlled cohort.

Comparative analysis of four nutritional scores in predicting adverse outcomes in biopsy-confirmed diabetic kidney Disease.

Malnutrition is associated with adverse outcomes in patients with diabetic kidney disease (DKD). However, it is uncertain which nutritional assessment tools are most effective in predicting the adverse outcomes of DKD. This retrospective study was conducted at a single center and included 367 patients diagnosed with DKD based on biopsy results between August 2009 and December 2018. Four nutritional assessment indices, namely the Prognostic Nutritional Index (PNI), Geriatric Nutritional Risk Index (GNRI), Triglycerides (TG) × Total Cholesterol (TC) × Body Weight (BW) Index (TCBI), and Controlling Nutritional Status (CONUT) score, were selected and calculated. We aimed to assess the association between these nutritional scores and adverse outcomes, including progression to end-stage kidney disease (ESKD), cardiovascular diseases events (CVD), and all-cause mortality. Univariate and multivariate Cox regression analyses, Kaplan-Meier analysis, along with Restricted cubic spline analysis were used to examine the relationship between nutritional scores and adverse outcomes. Furthermore, the area under the curve (AUC) was calculated using time-dependent receiver operating characteristics to determine the predictive value of the four nutritional scores alone and some combinations. Lastly, ordered logistic regression analysis was conducted to explore the correlation between the four nutritional scores and different renal histologic changes. The incidence of ESKD, CVD, and all-cause mortality was significantly higher in patients with DKD who had a lower PNI, lower GNRI, and higher CONUT score. Additionally, The TCBI performed the worst in terms of grading and risk assessment. The PNI offer the highest predictive value for adverse outcomes and a stronger correlation with renal histologic changes compared to other nutritional scores. Patients diagnosed with DKD who have a worse nutritional status are more likely to experience higher rates of adverse outcomes. The PNI might offer more valuable predictive values and a stronger correlation with different renal histologic changes compared to other nutritional scores.

Prognostic and clinicopathological significance of the Controlling Nutritional Status (CONUT) score in patients with lymphoma: a meta-analysis

ObjectivesThe role of the Controlling Nutritional Status (CONUT) scores in predicting the prognosis of lymphoma cases has been extensively explored, with no consistent results. The present meta-analysis focused on accurately...
