Impact of Controlling Nutritional Status Score on Comprehensive Clinical Outcomes in Patients With Chronic Limb-Threatening Ischemia in a Local Area of Super-Aged Society.

PURPOSE: This study aimed to evaluate the relationship between nutritional status and hospital outcomes in patients with chronic limb-threatening ischemia (CLTI) in a local area of contemporary super-aged society of Japan. MATERIALS AND METHODS: We analyzed 131 consecutive patients with 179 lower limb diseases admitted to our hospital for the treatment of CLTI between April 2018 and March 2023. These 131 patients were divided into 3 groups according to hospital outcomes: home discharge (HD), out-of-home discharge (OD), and in-hospital death (ID). Patient and lesion backgrounds were compared among the 3 groups, and a multivariable regression analysis was used to analyze the interaction between malnutrition and composite hard endpoints. RESULTS: The median age was 82.8 years, and non-ambulatory patients comprised 61.8% of the study population. The HD group included more ambulatory and fewer patients with higher CONUT score or inflammation than OD or ID group. The Rutherford classification and Wound, Ischemia, and foot Infection stage were significantly more severe in the ID group than in the HD group. Endovascular treatment (EVT) was more often implemented in the HD (94.9%) and OD (81.7%) groups than in the ID group (60.0%). However, all EVT procedures in the ID group were performed until as distally as possible to achieve the target arterial path success contrary to some EVT procedures in the HD or ID group that targeted lesions only above the knee. Multivariate analysis showed that a non-ambulatory state (hazard ratio [HR]=3.65, 95% confidence interval [CI]=1.48-9.02) and a higher controlling nutritional status (CONUT) score (≥5) (HR=7.46, 95% CI=1.66-33.6) were significant predictors for composite endpoints (major amputation or ID). Patients with lower CONUT scores (≤4) showed better outcomes in all indices including overall survival, major amputation-free survival, and wound healing. CONCLUSION: Condition of the CLTI patients represented by higher CONUT score emerged as the most influential predictor of major amputation or ID. Furthermore, non-ambulatory status or condition of higher CONUT score affects the destination after discharge. Implementing multidisciplinary approaches to address patients' nutritional state and physical disability, in addition to revascularization, may enhance comprehensive prognoses in patients with CLTI. CLINICAL IMPACT: In this single-center retrospective study, we analyzed prognoses of 131 consecutive patients with 179 lower limb diseases admitted for the treatment of chronic limb-threatening ischemia (CLTI) between April 2018 and March 2023. Our main finding was that condition of the CLTI patients represented by higher controlling nutritional status (CONUT) score was the most significant predictor of either major amputation or in-hospital death. Furthermore, condition of higher CONUT score or non-ambulatory status affects the destination after discharge. This suggests that multidisciplinary approaches to address patients' nutritional state and physical disability, in addition to revascularization, may enhance the prognosis in patients with CLTI. This is the first report to evaluate nutritional status associated with comprehensive hospital outcomes in addition to previously reported hard endpoints, such as major amputation or overall survival, and will be of great help in future clinical practice.

Associations of Preoperative Nutritional Status and Sarcopenia With Mortality in Patients With Abdominal Aortic Aneurysm After Open and Endovascular Abdominal Aortic Aneurysm Repair: A Retrospective Study.

OBJECTIVE: The effect of preoperative malnutrition and sarcopenia on outcomes in patients with abdominal aortic aneurysm (AAA) after open surgical repair (OSR) and endovascular abdominal aortic aneurysm repair is undefined. The authors conducted the study to address this issue in this population. DESIGN: A retrospective observational study. SETTING: A large tertiary hospital. PARTICIPANTS: Patients with AAA who underwent OSR and endovascular aneurysm repair (EVAR). INTERVENTIONS: Evaluation of nutritional status (Nutritional Risk Screening 2002 [NRS 2002] and the Controlling Nutritional Status [CONUT] scores), muscle size (skeletal muscle index), and postoperative parameters. MEASUREMENTS AND MAIN RESULTS: A total of 199 patients were reviewed from January 2020 to December 2022. Patients weew categorized into group A (CONUT <4) and group B (CONUT ≥4) based on whether their CONUT scores were less than 4. The mortality (p = 0.004) and the incidence of Clavien-Dindo class III complications (p = 0.007) in group B were higher than those in group A. CONUT score was an independent risk factor for midterm mortality (hazard ratio 1.329; 95% CI, 1.104-1.697; p = 0.002) and Clavien-Dindo class III complications (odds ratio 1.225; 95% CI, 1.012-1.482; p = 0.037) according to univariate and multivariate analyses, whereas NRS 2002 score and sarcopenia were not. Kaplan-Meier curves showed a lower midterm survival rate in group B (log-rank p < 0.001). CONCLUSION: In patients with AAA undergoing OSR or EVAR, a CONUT score ≥4 was associated with increased Clavien-Dindo class III complications and mortality. Preoperative nutritional status should be evaluated and optimized in this high-risk population.

Prognostic value of combined psoas muscle mass and controlling nutritional status in patients with pancreatic ductal adenocarcinoma: a retrospective cohort study.

BACKGROUND: Pancreatic ductal carcinoma (PDAC) is an extremely poor prognostic disease. Even though multidisciplinary treatment for PDAC has developed, supportive therapies, such as nutritional therapy or perioperative rehabilitation to sustain and complete aggressive treatment, have not yet been well-established in PDAC. The aim of this study was to elucidate the relationship between the combined index using psoas muscle mass index (PMI) values and controlling nutritional status (CONUT) score and prognosis. METHODS: We included 101 patients diagnosed with PDAC who underwent radical pancreatectomy with regional lymphadenectomy. The cut-off value was set at the first quartile (male, 6.3 cm2/m2; female 4.4 cm2/m2), and patients were classified into high PMI and low PMI groups. A CONUT score of 0 to 1 was classified as the normal nutritional status group, and 2 or more points as the malnutritional status group. Patients were further divided into three groups: high PMI and normal nutrition (good general condition group), low PMI and low nutrition (poor general condition group), and none of the above (moderate general condition group). We performed a prognostic analysis of overall survival (OS), stratified according to PMI values and CONUT scores. RESULTS: In the poor general condition group, the proportion of elderly people over 70 years of age was significantly higher than that in the other groups (p < 0.001). The poor general condition group had a significantly worse prognosis than the good and moderate general condition groups (p = 0.012 and p = 0.037). The 5-year survival rates were 10.9%, 22.3%, and 36.1% in the poor, moderate, and good general condition groups, respectively. In multivariate analysis, poor general condition, with both low PMI and malnutrition status, was an independent poor prognostic factor for postoperative OS (hazard ratio 2.161, p = 0.031). CONCLUSIONS: The combination of PMI and CONUT scores may be useful for predicting the prognosis of patients with PDAC after radical surgery.

Value of preoperative controlling nutritional status score in prognosis of patients with high-risk factors for early-stage cervical cancer.

Objective: To investigate whether the preoperative controlling nutritional status (COUNT) score is a prognostic factor of patients with high-risk factors for early-stage cervical cancer after surgery and concurrent chemoradiotherapy (CCRT). Methods: This was a retrospective study. From July 2017 to March 2021, a total of 354 patients with histologically confirmed FIGO stage IB-IIA cervical cancer undergoing surgery and postoperative CCRT were included at Hunan University of Medicine General Hospital, China. According to receiver operating characteristic (ROC) curve analysis, the patients were divided into a low CONUT score (< 3) group and a high CONUT score (≥ 3) group. Overall survival (OS) was used as the primary outcome measure and disease-free survival (DFS) as the secondary outcome measure. Results: Among the 354 patients, 239(67.5%) were included in the low CONUT score group and 115 (32.5%) in the high CONUT score group. The 3, 5 and 10-year OS rates in the low CONUT score group and high CONUT score group were respectively presenting statistically significant differences (p<0.001). The 3, 5 and 10-year DFS rates in the low CONUT score group and in the high CONUT score group were respectively with statistically significant differences (p<0.001). Multivariate Cox regression analysis showed that CONUT score, histological type, PNI and lymph node metastasis were all independent predictors for OS and DFS (all p<0.05). Conclusion: High preoperative CONUT score indicates poor prognosis of patients with high-risk factors for early-stage cervical cancer after surgery and postoperative CCRT. In clinical practice, consolidation chemotherapy is recommended for patients with high CONUT scores.

Comparison of the effectiveness of chemotherapy combined with immunotherapy and chemotherapy alone in advanced biliary tract cancer and construction of the nomogram for survival prediction based on the inflammatory index and controlling nutritional status score.

OBJECTIVE: To analyze the effectiveness of combining immune checkpoint inhibitors (ICIs) with first-line therapy in patients with advanced biliary tract cancer (BTC) and explore the biomarkers affecting the prognosis of immunotherapy, to construct a nomogram for the prediction of survival. METHODS: A retrospective study was conducted to include a total of 209 patients with advanced BTC treated in the first line from 2018 to 2022, divided into a combination therapy group (n = 129) and a chemotherapy-only group (n = 80) according to whether ICIs were applied in combination. Univariate and multifactorial COX regression analyses were performed on variables that may affect prognosis to identify independent influences on patient prognosis, and this was used to create nomograms, which were then prospectively validated and calibrated. RESULTS: The median progression-free survival (mPFS) and median overall survival (mOS) of patients in the combination therapy group were higher than those in the chemotherapy alone group [hazard ratio (HR) = 1.152, 95% confidence interval (CI): 0.7848-1.692, p = 0.0004, and HR = 1.067, 95% CI: 0.7474-1.524, p = 0.0016]. The objective response rate (ORR) of patients in the combination therapy and chemotherapy alone groups was 39.5% (51/129) vs. 27.5% (22/80), and the disease control rate (DCR) between the two groups was 89.9% (116/129) vs. 83.8% (67/80). Univariate analysis revealed the gender, presence of long-term tobacco and alcohol, degree of histological differentiation, serum albumin level, presence of liver metastases, presence of multi-visceral metastases, response, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), glycoprotein antigen 19-9 (CA19-9), systemic inflammatory index (SII), and controlling nutritional status (CONUT) scores were statistically significant with patient prognosis (all P values < 0.05). Multi-factor COX regression analysis was continued for the above variables, and the results showed that NLR, MLR, PLR, SII, and CONUT scores were independent influences on patients' OS (all p values < 0.05). A nomogram (C-index 0.77, 95% CI: 0.71-0.84) was created based on these independent influences and later validated using a validation cohort (C-index 0.75, 95% CI: 0.68-0.81). The time-dependent receiver operator characteristic curve (ROC) showed that the area under curve (AUC) of the training cohort patients at 12, 18, and 24 months was 0.72 (95% CI: 0.63-0.81), 0.75 (95% CI: 0.67-0.85), and 0.77 (95% CI: 0.66-0.87) and the AUC of the validation cohort was 0.69 (95% CI: 0.58-0.79), 0.74 (95% CI: 0.65-0.87), and 0.71 (95% CI: 0.64-0.89), respectively. Finally, calibration was performed using calibration curves, and the results showed that nomograms based on inflammatory metrics and CONUT scores could be used to assess survival (12, 18, and 24 months) in patients with advanced BTC treated with ICIs in the first line. CONCLUSION: Patients with advanced BTC benefit more from first-line treatment with standard chemotherapy in combination with ICIs than with chemotherapy alone. In addition, nomograms based on inflammatory metrics and CONUT scores can be used to predict survival at 12, 18, and 24 months in patients with advanced BTC treated with ICIs.

Prognostic impact of pretreatment skeletal muscle index and CONUT score in diffuse large B-cell Lymphoma.

BACKGROUND: Although the prognostic value of the Controlling Nutritional Status (CONUT) score in diffuse large B-cell lymphoma (DLBCL) has been reported in several previous studies, its clinical relevance for the presence of sarcopenia has not been assessed. METHODS: In this study, 305 DLBCL patients were reviewed. They were categorized into normal/mild (n = 219) and moderate/severe (n = 86) CONUT groups. Sarcopenia was assessed using the L3-skeletal muscle index measured by baseline computed tomography imaging. Based on CONUT score and sarcopenia, patients were grouped: A (normal/mild CONUT and no sarcopenia), B (either moderate/severe CONUT or sarcopenia, but not both), and C (both moderate/severe CONUT and sarcopenia). RESULTS: The moderate/severe CONUT group showed higher rates of ≥ grade 3 febrile neutropenia, thrombocytopenia, non-hematologic toxicities, and early treatment discontinuation not related to disease progression, compared to the normal/mild CONUT group. The moderate/severe CONUT group had a lower complete response rate (58.1% vs. 80.8%) and shorter median overall survival (18.5 vs. 162.6 months) than the normal/mild group. Group C had the poorest prognosis with a median survival of 8.6 months, while groups A and B showed better outcomes (not reached and 60.1 months, respectively). Combining CONUT score and sarcopenia improved the predictive accuracy of the Cox regression model (C-index: 0.763), compared to the performance of using either CONUT score (C-index: 0.754) or sarcopenia alone (C-index: 0.755). CONCLUSIONS: In conclusion, the moderate/severe CONUT group exhibited treatment intolerance, lower response, and poor prognosis. Additionally, combining CONUT score and sarcopenia enhanced predictive accuracy for survival outcomes compared to individual variables.

The prognostic value of controlling nutritional status (CONUT) score-based nomogram on extranodal natural killer/T cell lymphoma patients.

Controlling nutritional status (CONUT) score as an original nutritional assessment tool can be used to assess the prognosis of patients with a variety of malignancies. However, the predictive power of CONUT in extranodal natural killer/T cell lymphoma (ENKTL) patients has never been demonstrated. Our retrospective multicenter study aimed to explore the prognostic value of CONUT in newly diagnosed ENKTL. A total of 1085 newly diagnosed ENKTL patients between 2003 and 2021 were retrospectively retrieved. Cox proportional hazard model was used to explore the prognostic factors of overall survival (OS). The survival rate of ENKTL was evaluated using Kaplan-Meier analysis, and log-rank test was applied to the difference between groups. We investigated the prognostic performance of CONUT, the International Prognostic Index (IPI), the Korean Prognostic Index (KPI), and the Prognostic Index of Natural Killer Cell Lymphoma (PINK) using the receiver operating characteristic (ROC) curve and decision curve analysis (DCA). The median age at diagnosis for the whole cohort was 47 years, and the male to female ratio was 2.2:1. The 5-year OS for all patients was 72.2%. Multivariable analysis showed that CONUT, age, bone marrow involvement, ECOG PS score, and Chinese Southwest Oncology Group and Asia Lymphoma Study Group ENKTL stage were identified as independent predictive factors for OS. Based on multivariable results, a prognostic nomogram was developed. Subgroup analysis demonstrated that patients with severe malnutrition had poorest clinical outcome. In addition, ROC curves and DCA analysis proved that compared with IPI, KPI, and PINK models, the CONUT score-based nomogram showed a better prognostic predictive efficiency of ENKTL. CONUT could effectively stratify the prognosis of ENKTL and the proposed nomogram based on CONUT was an effective prognostic model for prediction.

Assessing the Predictive Value of Different Nutritional Indexes for Contrast-Associated Acute Kidney Injury in Patients Undergoing Percutaneous Coronary Intervention.

BACKGROUND: The link between malnutrition and poor prognosis in cardiovascular disease has been established but the association between malnutrition and contrast-associated acute kidney injury (CA-AKI), a common complication of coronary procedures, remains poorly understood. In this study we investigated the predictive value of 3 nutritional indexes for CA-AKI in patients undergoing percutaneous coronary intervention (PCI).Methods and Results: The study included a total of 6,049 consecutive patients undergoing PCI between May 2012 and September 2020, among whom 352 (5.8%) developed CA-AKI. We used the Controlling Nutritional Status (CONUT) score, the Geriatric Nutritional Risk Index (GNRI), and the Prognostic Nutritional Index (PNI) to assess the association between malnutrition risk and CA-AKI after PCI. Multivariate logistic regression analysis revealed that malnutrition, as identified by GNRI and PNI, was significantly associated with a higher risk of CA-AKI (moderate-severe malnutrition in GNRI: odds ratio [OR]=1.92, [95% confidence interval (CI), 1.27-2.85]; malnutrition in PNI: OR=1.87, [95% CI, 1.39-2.50]), whereas the CONUT score did not demonstrate a significant difference (P>0.05). Furthermore, GNRI (∆AUC=0.115, P<0.001) and PNI (∆AUC=0.101, P<0.001) exhibited superior predictive ability than the CONUT score for CA-AKI and significantly improved reclassification and discrimination in the fully adjusted model. CONCLUSIONS: Malnutrition, especially identified by the GNRI and PNI, was associated with a higher risk of CA-AKI after PCI. GNRI and PNI performed better than the CONUT score in predicting CA-AKI.

Comparison of three nutritional assessment methods associated with the prognostic impact of laryngeal cancer.

BACKGROUND: Several studies have found that the prognostic nutritional index (PNI), controlling nutritional status (CONUT), and Glasgow Prognostic Score (GPS) of patients with laryngeal cancer accurately predict their prognosis. However, there is no consensus regarding the best assessment tool. Therefore, this study aimed to confirm the predictive value of the three nutritional scoring systems for the prognosis of patients with laryngeal cancer. METHODS: This study analyzed a cohort of 427 patients with laryngeal cancer who visited our hospital. PNI, CONUT, and GPS were calculated, and the relationship between these indicators and prognosis was examined. RESULTS: The optimal cut-off levels for overall survival (OS) of laryngeal cancer patients determined by PNI, CONUT, and GPS were 45, 3, and 0, respectively. When patients were stratified based on these thresholds, OS and disease-free survival (DFS) were significantly decreased in the malnutrition group (all three, p < 0.05). The OS rates of patients with laryngeal cancer were significantly affected by the three scores according to multivariate analysis. CONCLUSIONS: The three scoring methods had a high predictive value for the prognosis of patients with laryngeal cancer, with GPS having the strongest correlation with the prognosis of laryngeal cancer patients.

Prognostic Ability of Nutritional Indices for Outcomes of Bladder Cancer: A Systematic Review and Meta-Analysis.

BACKGROUND: Nutrition has become an important parameter influencing the prognosis of several cancers. However, its impact on outcomes for bladder cancer (BC) is still unclear. This review examines the association between three commonly used nutritional indices, namely, the prognostic nutritional index (PNI), controlling nutritional status (CONUT), and the geriatric nutritional risk index (GNRI) and outcomes of BC. METHODS: PubMed, CENTRAL, Scopus, Web of Science, Embase, and Google Scholar were explored for studies published up to April 13, 2023. Data from studies were pooled to examine the association between PNI, CONUT, or GNRI and overall survival (OS) and recurrence-free survival (RFS). RESULTS: Thirteen studies were included. Meta-analysis demonstrated significantly poor OS with low PNI versus high PNI in BC patients (hazard ratio [HR]: 1.71; 95% confidence interval [CI]: 1.37, 2.14; I2 = 0%). This result remained significant in various subgroup analyses. However, no association was noted between PNI and RFS (HR: 1.22; 95% CI: 0.67, 2.24; I2 = 84%). Meta-analysis showed that patients with high CONUT scores had significantly poor OS (HR: 2.43; 95% CI: 1.82, 3.25; I2 = 0%) as well as RFS (HR: 2.90; 95% CI: 2.10, 4.01; I2 = 0%). Data on GNRI were scarce and conflicting. CONCLUSION: Limited data show that PNI and CONUT are predictive of outcomes in BC. Low PNI was associated with poor OS, while high CONUT was associated with poor OS and RFS. Data on GNRI are too scarce to obtain conclusions. Further studies are needed to supplement the results.

Evaluation of three nutritional indices as predictors of 2-year mortality and major amputation in patients with chronic limb-threatening ischemia.

OBJECTIVE: The present study aimed to examine which nutritional index, such as the controlling nutritional status (CONUT), prognostic nutritional index (PNI), and geriatric nutritional risk index (GNRI), is better for predicting prognosis in patients with chronic limb-threatening ischemia (CLTI) following revascularization. METHOD: We retrospectively analyzed data of patients who underwent revascularization for CLTI between 2008 and 2020. The endpoints were 2-year overall survival and limb salvage. The optimal cutoff values of 2-year overall survival and major amputation were determined by receiver operating characteristic curve analyses. RESULT: A total of 238 patients with CLTI and 289 limbs were analyzed. The 2-year overall survival rates were 48.9%, 54.6%, and 53.5% in patients with CONUT score ≥4, PNI score <42.6, and GNRI <98.4 compared with 80.0%, 80.0%, and 78.4% in patients with CONUT score <4, PNI score ≥42.6, and GNRI ≥98.4 (p < 0.01). Age, non-ambulatory status, hemodialysis, and nutritional indices were independent risk factors for 2-year mortality in the multivariate analyses. The 2-year limb salvage rates were 70.1%, 82.2%, and 81.9% in patients with CONUT score ≥7, PNI score <41.9, and GNRI <95.3 compared with 92.8%, 98.3%, and 94.2% in patients with CONUT score <7, PNI score ≥41.9, and GNRI ≥95.3 (p < 0.01). Wound, ischemia, and foot infection stage and each nutritional index (CONUT and PNI) were independent risk factors for major amputation in multivariate analyses. The overall survival and limb salvage rates of patients with malnutrition diagnosed by CONUT score were poor compared with those of normal nutrition or malnutrition diagnosed by PNI and/or GNRI scores. CONCLUSION: The CONUT, PNI, and GNRI scores can predict the 2-year overall survival in patients with CLTI after revascularization. The CONUT and PNI scores were associated with major amputation.

Associations among Preoperative Malnutrition, Muscle Loss, and Postoperative Walking Ability in Intertrochanteric Fractures: A Retrospective Study.

Sarcopenia and malnutrition are increasing in older adults and are reported risk factors for functional impairment after hip fracture surgery. This study aimed to investigate the associations between skeletal muscle mass loss, malnutrition, and postoperative walking ability in patients with hip fracture. We retrospectively reviewed patients who underwent intertrochanteric fracture surgery at our institute. The psoas muscle index, controlling nutritional status score, and functional ambulation category (FAC) were used to evaluate skeletal muscle mass, nutritional status, and walking ability, respectively. Six months after surgery, walking ability was assessed as either "gait disturbance" or "independent gait". Multivariate binomial logistic regression analysis, with skeletal muscle mass, nutritional status, and other factors, was used to predict the risk of being assigned to the gait disturbance group. This study included 95 patients (mean age, 85.2 years; 70 women). Sixty-six patients had low skeletal muscle mass, 35 suffered from malnutrition, and 28 had both. Malnutrition and low skeletal muscle mass were significantly associated with postoperative gait disturbance (FAC < 3). Preoperative low skeletal muscle mass and malnutrition were risk factors for postoperative poor walking ability. Further preventive interventions focusing on skeletal muscle mass and nutritional status are required.

Which preoperative immunonutritional index best predicts postoperative mortality after palliative surgery for malignant bowel obstruction in patients with late-stage cancer? A single-center study in Japan comparing the modified Glasgow prognostic score (mGPS), the prognostic nutritional index (PNI), and the controlling nutritional status (CONUT).

PURPOSE: To compare the utility of preoperative immunonutritional parameter measures for predicting postoperative mortality following palliative surgery (PS) for malignant bowel obstruction (MBO) in patients with late-stage cancer. METHODS: The subjects of this retrospective study were 83 late-stage cancer patients with MBO who underwent PS between January, 2005 and December, 2018, at a single institution in Japan. We compared the modified Glasgow prognostic score (mGPS), the prognostic nutritional index (PNI), and the controlling nutritional status (CONUT) for predicting postoperative mortality following PS in these patients. RESULTS: The most prevalent cancer in the patients who underwent PS was colorectal cancer (54.2%), followed by gastric cancer (24.1%). Postoperative complications of Clavien-Dindo classification grade ≥ 2 developed in 32 (38.6%) patients and stoma-related complications developed in 26 (31.3%) patients. There were 15 (18.1%) patients with 60-day mortality, 22 (26.5%) with 90-day mortality, and 4 (4.8%) with 30-day mortality. Multivariable analysis identified only mGPS as being associated with 60-day mortality (odds ratio, 9.387; 95% confidence interval, 0.001-4.478; p = 0.049). The overall survival of patients with a mGPS score of 2 was significantly worse than that of those with a mGPS score of < 2 (p = 0.013). CONCLUSIONS: These results suggest that the mGPS is a good predictor not only of 60-day mortality, but also of the overall survival of patients with late-stage cancer and MBO.

Association of Pre-procedural Nutritional Indicators with Periprocedural Myocardial Infarction in Patients Undergoing Elective Percutaneous Coronary Intervention.

Nutritional risk is closely related to the poor prognosis of hospitalized patients. However, the association of pre-procedural nutritional risk with periprocedural myocardial infarction (PMI) after percutaneous coronary intervention (PCI) remains unclear.A total of 22,267 patients who underwent elective PCI were enrolled in this retrospective cross-sectional study. Nutritional risk was evaluated by three nutritional risk assessment tools, namely, controlling nutritional status (CONUT), prognostic nutritional index (PNI), and geriatric nutritional risk index (GNRI). PMI after PCI was defined as elevation of cardiac troponin I (cTnI) values > 5 × 99th percentile upper reference limit. Linear regression analysis was performed to explore the association of nutritional risk assessment tools with cTnI fold elevation. Log-binomial regression analysis was conducted to determine the association of nutritional risk assessment tools with PMI.The average age of the enrolled patients was 66.4 years old, and 2,647 of them (11.9%) suffered PMI after PCI. Multivariable linear regression analysis determined a linear association between nutritional risk assessment tools and cTnI fold elevation (CONUT: ß = 0.220, 95% CI [0.088-0.352], P = 0.001; PNI: ß = -0.105, 95% CI [-0.146 to -0.065], P < 0.001; GNRI: ß = -0.090, 95% CI [-0.122 to -0.057], P < 0.001). Log-binomial regression analysis showed that nutritional risk assessment tools were strongly associated with PMI after PCI (CONUT [4-12 versus 0-1]: RR = 1.168, 95% CI [1.054-1.295], P = 0.003; PNI [< 44 versus ≥ 52]: RR = 1.168, 95% CI [1.038-1.315], P = 0.010; GNRI [< 98 versus ≥ 108]: RR = 1.128, 95% CI [1.006-1.264], P = 0.039).Pre-procedural nutritional status, assessed by CONUT, PNI, and GNRI, was significantly and strongly associated with PMI in patients undergoing elective PCI.

Risk factor analysis for diabetic foot ulcer-related amputation including Controlling Nutritional Status score and neutrophil-to-lymphocyte ratio.

Diabetic foot ulcer often leads to amputation, and both nutritional status and immune function have been associated with this process. We aimed to investigate the risk factors of diabetic ulcer-related amputation including the Controlling Nutritional Status score and neutrophil-to-lymphocyte ratio biomarker. We evaluated data from hospital in patients with diabetic foot ulcer, performing univariate and multivariate analyses to screen for high-risk factors and Kaplan-Meier analysis to correlate high-risk factors with amputation-free survival. Overall, 389 patients underwent 247 amputations over the follow-up period. After correction to relevant variables, we identified five independent risk factors for diabetic ulcer-related amputation: ulcer severity, ulcer site, peripheral arterial disease, neutrophil-to-lymphocyte ratio and nutritional status. Amputation-free survival was lower for the moderate-to-severe versus mild cases, for the plantar forefoot versus hindfoot location, for the concomitant peripheral artery disease versus without and in the high versus low neutrophil-to-lymphocyte ratio (all p < 0.01). The results showed that ulcer severity (p < 0.01), ulcer site (p < 0.01), peripheral artery disease (p < 0.01), neutrophil-to-lymphocyte ratio (p < 0.01) and Controlling Nutritional Status score (p < 0.05) were independent risk factors for amputation in diabetic foot ulcer patients and have predictive values for diabetic foot ulcer progression to amputation.

Impact of Controlling nutritional status (CONUT) in patients with unresectable advanced pancreatic cancer receiving multi-agent chemotherapy: A single center, retrospective cohort study.

Controlling nutritional status (CONUT) calculated using the serum albumin concentration, total lymphocyte count, and total cholesterol, was developed as a screening tool for the early detection of undernutrition. In addition, CONUT has been reported to be a prognostic predictor of various malignancies. AIM: To investigate the impact of CONUT in patients with advanced pancreatic cancer (APC). METHODS: Between June 2014 and October 2020, 110 consecutive patients with APC who received multi-agent chemotherapy were retrospectively reviewed. Patients were classified into four categories (normal, 1; light, 2; moderate, 3; severe, 4) based on CONUT. Progression-free survival (PFS) and overall survival (OS) were evaluated. RESULTS: Thirty-nine (35.4%), 63 (57.2%), and 8 (7.2%) patients had CONUT 1, 2, and 3, respectively, but no patients for CONUT 4. The baseline characteristics did not differ significantly between CONUT classifications. In the multivariate analyses, the presence of metastasis (hazard ratio [HR], 2.06; 95% confidence interval [CI], 1.22-3.52), CONUT 2 (HR, 2.15; 95% CI, 1.32-3.54), and CONUT 3 (HR, 9.18; 95% CI, 2.67-23.50) were independent risk factors for PFS. The presence of metastasis (HR, 1.76; 95% CI, 1.04-3.07), CONUT 2 (HR, 1.92; 95% CI, 1.16-3.24), and CONUT 3 (HR, 10.71; 95% CI, 3.87-27.63) were also independent risk factors for OS. A median OS in CONUT 1, 2, and 3 were 20, 14.5, and 3.5 months (CONUT 1 vs. CONUT 2, p = 0.02; CONUT 1 vs. CONUT 3, p < 0.01; CONUT 2 vs. CONUT 3, p < 0.01), respectively. CONCLUSION: CONUT could be a predictor of prognosis for survival in patients with APC.

Nomograms including the controlling nutritional status score in patients with hepatocellular carcinoma undergoing transarterial chemoembolisation for prediction survival: a retrospective analysis.

This retrospective study investigated the predictive value of the Controlling Nutritional Status (CONUT) score in patients with intermediate-stage hepatocellular carcinoma (HCC) who received transarterial chemoembolization (TACE). Nomograms were developed to predict progression-free and overall survival (PFS, OS). The medical data of 228 patients with HCC and treated with TACE were collected. The patients were apportioned to 2 groups according to CONUT score: low or high (<4, ≥4). Univariate and multivariate analyses were performed using Cox regression for OS and PFS. OS and PFS were estimated by the Kaplan-Meier curve and compared with the log-rank test. Nomograms were constructed to predict patient OS and PFS. The nomograms were evaluated for accuracy, discrimination, and efficiency. The cut-off value of CONUT score was 4. The higher the CONUT score, the worse the survival; Kaplan-Meier curves showed significant differences in OS and PFS between the low and high CONUT score groups (P = 0·033, 0·047). The nomograms including CONUT, based on the prognostic factors determined by the univariate and multivariate analyses, to predict survival in HCC after TACE were generated. The CONUT score is an important prognostic factor for both OS and PFS for patients with intermediate HCC who underwent TACE. The cut-off value of the CONUT score was 4. A high CONUT score suggests poor survival outcomes. Nomograms generated based on the CONUT score were good models to predict patient OS and PFS.

A prospective epidemiological analysis of controlling nutritional status score with the poor functional outcomes in Chinese patients with haemorrhagic stroke.

Nutritional Risk Screening index is a standard tool to assess nutritional risk, but epidemiological data are scarce on controlling nutritional status (CONUT) as a prognostic marker in acute haemorrhagic stroke (AHS). We aimed to explore whether the CONUT may predict a 3-month functional outcome in AHS. In total, 349 Chinese patients with incident AHS were consecutively recruited, and their malnutrition risks were determined using a high CONUT score of ≥ 2. The cohort patients were divided into high-CONUT (≥ 2) and low-CONUT (< 2) groups, and primary outcomes were a poor functional prognosis defined as the modified Rankin Scale (mRS) score of ≥ 3 at post-discharge for 3 months. Odds ratios (OR) with 95 % confidence intervals (CI) for the poor functional prognosis at post-discharge were estimated by using a logistic analysis with additional adjustments for unbalanced variables between the high-CONUT and low-CONUT groups. A total of 328 patients (60·38 ± 12·83 years; 66·77 % male) completed the mRS assessment at post-discharge for 3 months, with 172 patients at malnutrition risk at admission and 104 patients with a poor prognosis. The levels of total cholesterol and total lymphocyte counts were significantly lower in high-CONUT patients than low-CONUT patients (P = 0·012 and < 0·001, respectively). At 3-month post discharge, there was a greater risk for the poor outcome in the high-CONUT compared with the low-CONUT patients at admission (OR: 2·32, 95 % CI: 1·28, 4·17). High-CONUT scores independently predict a 3-month poor prognosis in AHS, which helps to identify those who need additional nutritional managements.

The prognostic value of the Controlling Nutritional Status score on patients undergoing nephrectomy for upper tract urothelial carcinoma or renal cell carcinoma: a systematic review and meta-analysis.

In recent years, the controlling nutritional status (CONUT) score has increasingly became an effective indicator associated with tumor prognosis. This study was conducted to synthesise data on the prognostic value of CONUT score on patients with upper tract urothelial carcinoma (UTUC) or renal cell carcinoma (RCC) undergoing nephrectomy. We designed and performed a systematic analysis of studies that verified the correlation between preoperative CONUT score and prognosis for UTUC and RCC using PubMed, Web of Science and Embase. The conclusion was clarified by pooled hazard ratios (HR) and 95% confidence intervals (95% CI). Subgroup analysis were further conducted in accordance with different primary tumor. Six studies involving 3529 patients were included in this evidence synthesis, which revealed that the CONUT score had a potential role to predict the survival of UTUC and RCC patients accepting surgery. Pooled analysis showed that the overall survival (OS, HR 2·32, p < 0·0001), cancer-specific survival (CSS, HR 2·68, p < 0·0001) and disease-free survival (DFS, HR 1·62, p < 0·00001) were inferior in the high CONUT score group when compared with low score group. Subgroup analysis revealed that this result was in line with UTUC (OS: HR 1·86, p = 0·02; CSS: HR 2·24, p = 0·01; DFS: HR 1·54, p < 0·00001) and RCC (OS: HR 3·05, p < 0·00001; CSS: HR 3·47, p < 0·00001; DFS: HR 2·21, p = 0·0005) patients respectively. Consequently, the CONUT score is a valuable preoperative index to predict the survival of patients with UTUC or RCC undergoing nephrectomy.

Comparison of nutritional and immunological scoring systems predicting prognosis in T1-2N0 colorectal cancer.

PURPOSE: Previous studies have shown that the new nutritional and immunological status scoring systems of the Naples prognostic score (NPS), controlling nutritional status score (CONUT), and the older prognostic nutritional index (PNI) are independent predictors in colorectal cancer. This study compares the prognostic value of NPS, CONUT, and PNI in T1-2N0 colorectal cancer. METHODS: We retrospectively evaluated 305 consecutive stage I (T1-2N0M0) colorectal cancer patients who underwent radical surgery from January 2010 to December 2015 at our hospital. The NPS results were divided into 3 groups (0, 1, and 2 groups), and the PNI and CONUT results were divided into 2 groups (low and high groups). RESULTS: The patients with low PNI had worse overall survival (OS) and disease-free survival (DFS) than those with high PNI (P < 0.001 and P < 0.001, respectively). Multivariate analysis showed that PNI was independently associated with OS and DFS (P < 0.001 and P < 0.001, respectively), but NPS and CONUT results were not. CONCLUSION: The PNI is an independent predictor in stage I colorectal cancer, but NPS and CONUT results are not.
