Complete laparoscopic and Da Vinci robot esophagogastric anastomosis double muscle flap plasty for radical resection of proximal gastric cancer.

To investigate the application value of complete laparoscopy and Da Vinci robot esophagogastric anastomosis double muscle flap plasty in radical resection of proximal gastric cancer. A retrospective descriptive study was used. The clinicopathological data of 35 patients undergoing radical operation for proximal gastric cancer admitted to Liaoning Cancer Hospital from January 2020 to December 2023 were collected. Variables evaluated: 1. Transoperative,2. Postoperative, 3. Follow-up. In relation to follow-up, esophageal disease status reflux, anastomosis, nutritional status score, serum hemoglobin, tumor recurrence, and metastasis were investigated. The trans and postoperative variables were obtained from the clinical records and the patients were followed up in outpatient department and by telephone. Among the 35 patients, 17 underwent robotic surgery and 18 underwent laparoscopic surgery. There were 29 males and 6 females. 1) Transoperative: Robotic surgery: The operation time was (305.59 ± 22.07) min, the esophagogastric anastomosis double muscle flap plasty time was (149.76 ± 14.91) min, the average number of lymph nodes cleared was 30, and the average intraoperative blood loss was 30 ml. Laparoscopic surgery: The mean operation time was 305.17 ± 26.92min, the operation time of esophagogastric anastomosis double muscle flap was (194.06 ± 22.52) min, the average number of lymph nodes cleared was 24, and the average intraoperative blood loss was 52.5 ml. 2) Postoperative: Robotic surgery: the average time for patients to have their first postoperative anal emission was 3 days, the average time to first postoperative feeding was 4 days, and the average length of hospitalization after surgery was 8 days. Laparoscopic surgery: the average time for patients to have their first postoperative anal emission was 5 days, the average time to first postoperative feeding was 6 days, the average length of hospitalization after surgery was 10 days. 3) Follow-up: The follow-up time ranged from 1 to 42 months, with a median follow-up time of 24 months. Complete Da Vinci robot and laparoscopic esophagogastric anastomosis double muscle flap plasty for radical resection of proximal gastric cancer can minimize surgical incision, reduce abdominal exposure, accelerate postoperative recovery of patients, and effectively prevent reflux esophagitis and maintain good hemoglobin concentration and nutritional status. The advantages of robotic surgery is less intraoperative bleeding and faster post-surgical recovery, but it is relatively more expensive.

Prospective observational study of nutritional and immunological indices as predictive biomarkers of response to immune checkpoint inhibitors in non-small cell lung cancer (ICI-PREDICT study).

e20524 Background: Nutritional and immunological indices, including controlling nutritional status (CONUT) score, skeletal muscle area (SMA), and neutrophil-to-lymphocyte ratio (NLR) have been reported as predictors of response to immune checkpoint inhibitor (ICI) in non-small cell lung cancer (NSCLC). The aim of this prospective, multicenter study is to evaluate the clinical impact of pre- or early post-treatment changes in nutritional and immunological indices on treatment outcomes in patients with advanced NSCLC treated with first-line ICIs. Methods: We enrolled 301 advanced NSCLC patients treated with ICIs (monotherapy or combined with chemotherapy) as first-line therapy, without any oncogene mutations, and available data on programmed cell death-ligand 1 (PD-L1) expression (150 in training and 151 in validation cohorts) from March 2020 to November 2022. The CONUT score, SMA at the L3 level (cm2/m2), and NLR, were evaluated before treatment initiation and at the first response evaluation. Cut-off values were determined by receiver operating characteristic curves with objective response as the outcome in the training cohort. The primary endpoint was progression-free survival (PFS). For exploratory study, serum before treatment was collected to measure 15 muscle-derived cytokines (Apelin, BDNF, CX3CL1, EPO, FABP3, FSTL1, FGF21, IL-6, IL-15, Irisin, LIF, Musclin, Myostatin, OSM, and SPARC) (n = 123). Results: The median follow-up period and PFS was 17.5 (range: 7.3-39.4) and 6.9 (range: 0.1-31.5) months, respectively. In the training cohort, men (hazard ratio [HR]: 0.52, 95% confidence interval [CI]: 0.30-0.90, p = 0.0183), ΔCONUT < 0 (HR: 0.59, 95% CI: 0.35-0.98, p = 0.0431), and ΔSMA > −0.13 (HR: 0.56, 95% CI: 0.33-0.96, p = 0.0333) were independent predictors for PFS. In the validation cohort, PD-L1 ≥ 50% (HR: 0.54, 95% CI: 0.34-0.84, p = 0.0061), NLR < 3.65 (HR: 0.47, 95% CI: 0.30-0.74, p = 0.0011), and ΔSMA > −0.13 (HR: 0.61, 95% CI: 0.38-0.98, p = 0.0421) were independent predictors for PFS. In the exploratory study, multivariate analysis including muscle-derived cytokines (continuous variables) revealed that performance status = 0 (HR: 0.24, 95% CI: 0.12-0.48, p < 0.0001), without baseline prednisone (≥ 10 mg/day) (HR: 0.17, 95% CI: 0.05-0.58, p = 0.0213), smoking history (HR: 0.34, 95% CI: 0.14-0.81, p = 0.0269), and FSTL1 (HR: 0.97, 95% CI: 0.93-0.99, p = 0.0185) were independent predictors of PFS. Conclusions: ΔSMA was the only factor validated as an independent predictor of PFS. The underlying biological mechanisms may be related to skeletal muscle-derived FSTL1.

Correlation of plasma GDF15 with aging, organ disfunction, sarcopenia, and postoperative infectious complication in patients with esophageal cancer.

e16088 Background: The age of cancer incidence is increasing every year. Along with it, cancer patients getting has more comorbidity and decreasing muscle strength which may lead to increase postoperative complications. Especially, since esophageal cancer (EC) patients have heavy drinking and smoking history and high age of morbidity, they usually have multiple comorbidities and so that they particularly have high incidence of cachexia. A novel inflammatory marker known as growth differentiation factor 15 (GDF15) has been recently reported relation with cancer cachexia. This study conducted to evaluate correlation between clinical data which suggested cachexia of EC patients and plasma GDF15. Methods: Eighty-one esophageal cancer patients who first visited our outpatient ward from July 2021 to March 2023 were enrolled in this study. After obtaining consent for the study, plasma samples collected before starting any treatment for the cancer. The quantification of GDF15 was performed by ELISA. Clinical information was collected from clinical record including age, comorbidities, biochemical data, Controlling Nutritional Status (CONUT) score, and Skeletal Mass Index (SMI). GDF15 was then evaluated for clinical impact by comparison with postoperative results. Mann-Whitney U test, student-t test, ANOVA were used appropriately to analyze the relationship between the GDF-15 and patient characteristics and post operative complications. Multivariate analysis ware used logistic regression analysis. P-values < 0.05 were considered statistically significant for all statistical analyses. Results: Mean age was 68.3-year-old and 80.3% of these were male. Malnutrition patients diagnosed by using CONUT were 24 (29.6%) and sarcopenia patients diagnosed by using SMI were 21 (25.9%). The median value of GDF15 was 1165 pg/mL with its range were from 298 to 9100 pg/mL. Plasma GDF15 was statistically correlated with age ( P< 0.001), performance status ( P= 0.046), prevalence of hypertension ( P= 0.045) and/or diabetes ( P= 0.018), serum level of aspartate aminotransferase (AST) ( P< 0.001)/ γ-glutamyltransferase (γ-GTP) ( P< 0.001)/ creatinine ( P= 0.004)/ blood sugar ( P= 0.028), and SMI ( P= 0.003). Seventy-two patients underwent curative surgery, and no perioperative death was observed. The patients who occurred anastomotic leakage and infectious complication observed statistically higher GDF15 than those without (P = 0.030, P = 0.016). Optimal cut-off value was detected as 940 ng/mL for detecting infectious complication by ROC-curve with AUC value of 0.68. Conclusions: This study showed GDF15 is potentially suggesting deterioration of general condition, which came from aging, organ disfunction, and decreasing muscle mass, which may lead to cachexia in EC patients. In addition, higher GDF15 patients have risk of postoperative infectious complication.

Pan-cancer G2C-Pro: A two-stage Gaussian clustering to prognostically stratify patients with advanced tumors treated with immune checkpoint inhibitors.

e13605 Background: Immune checkpoint inhibitors (ICIs) have revamped the clinical outcomes of patients (pts) affected by advanced solid tumors. The aim of our study is to develop a two-stage Gaussian Clustering algorithm (G2C) integrated with a logistic regression model (Pro) to prognostically stratifypts with advanced solid tumors treated with ICIs (pan-cancer G2C-Pro) based on baseline features. Methods: Data extraction involved, retrospectively, pts with advanced solid tumors (lung, melanoma, renal cancer, head and neck, urothelial carcinoma) treated with ICIs at Department of Medical Oncology, Ancona. Baseline body mass composition (BC) was assessed through computed tomography (CT) scan at L3 level, abstracting subcutaneous and visceral fat and muscle mass indicators. Moreover, baseline clinicopathologic features, nutritional status through The Controlling Nutritional Status (CONUT) score, and comorbidities were collected. An unsupervised clustering analysis was used to identify two groups of pts with different BC phenotype risk groups. Then, another unsupervised clustering analysis was used to identify two groups of pts within the dataset that hold prognostic significance according to BC risk groups, clinicopathologic features, CONUT score, and comorbidities. G2C was constructed by sequentially integrating two Gaussian Mixture models, each employing K-means++ initialization. Next, Pro was used to predict clusters’ label. The metrics used to evaluate the average performance of Pro on test sets were ACCuracy (ACC) and Area Under the Curve (AUC). The model was developed in Python on-cloud using the Google Colab service. Results: A total of 87 pts with complete data available were included in the final analysis. The two generated clusters for BC phenotype were BC_Low_Risk (n = 39) and BC_High_Risk (n = 48). Then, considering BC risk groups, clinicopathologic features, nutritional status, and comorbidities, two generated clusters were cluster 1 (n = 55) and cluster 2 (n = 32). Looking at clinical outcomes, median progression free survival was 16.1 months for cluster 1 versus 7.1 months for cluster 2 (HR: 0.57, 95% CI: 0.33-0.98, p = 0.04), and median overall survival was 41.8 months for cluster 1 versus 10.5 months for cluster 2 (HR: 0.47, 95% CI: 0.27-0.83, p = 0.008). The average ACC and AUC across all splits achieved by Pro model for patient classification into clusters were 0.94 and 0.89, respectively. From the feature ranking, it emerged that the one with higher importance was CONUT score, followed by BC phenotype risk groups and neutrophil-to-lymphocyte ratio. Conclusions: By using an easy-to-obtain and reproducible baseline BC, clinicopathologic, nutritional features, and comorbidities, we demonstrated that pan-cancer G2C-Pro is a promising and accurate prognostic model for stratifying pts with advanced tumors treated with ICIs.

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

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). 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. 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.

Evaluation of controlling nutritional status (CONUT) score in the prognosis of hyperemesis gravidarum.

To investigate the predictive value of the Controlling Nutritional Status (CONUT) score on hyperemesis gravidarum (HG) severity, hospitalization, and length of stay. This retrospective cross-sectional study, conducted between December 2022 and June 2023, involved two groups. Group 1 comprised 52 pregnant women diagnosed with HG in the first trimester, receiving hospitalization and treatment. Group 2 included 105 pregnant women diagnosed with HG in the first trimester, managed and treated as outpatients. The CONUT score was calculated with the formula: Serum albumin score+total lymphocyte score+total cholesterol score. This score is calculated with a number of points between 0 and 12. The interpretation of the score involves four categories: normal (0-1), light (2-4), moderate (5-8), and severe (9-12). The CONUT score differed significantly between the hospitalized (4, IQR: 2.25-5) and outpatient groups (2, IQR: 2-3) (p<0.001). A CONUT score >3 was associated with the need for hospitalization, demonstrating a sensitivity of 60%, aspecificity of 84% (p<0.001). The CONUT score was the parameter with the highest odds ratio (OR) value among the parameters related to the need for hospitalization, and each unit increase in the CONUT score increased the need for hospitalization by 1.683 times [OR=1.683 (95% CI: 1.042-2.718), p=0.033]. A positive correlation was found between the CONUT score and the duration of hospital stay (r=0.316, p=0.023). This study suggests CONUT score as a valuable tool for predicting HG severity, hospitalization need, and duration of hospital stay.

Impact of prognostic nutritional index on the occurrence of post-operative delirium after total knee arthroplasty

PurposeDelirium has been reported to cause delayed functional recovery, prolonged hospitalization, future institutionalization, increased mortality, and increased healthcare costs. However, there are no reports on how prognostic nutritional index (PNI), Controlling Nutritional Status (CONUT) score, and geriatric nutritional risk index (GNRI) are related to delirium after total knee arthroplasty (TKA). This study aimed to identify risk factors for post-operative delirium after TKA using various pre-operative nutritional assessments (PNI, CONUT score, and GNRI). MethodsIn total, 289 patients who underwent primary TKA between September 2011 and April 2022 in our institute (Hamamatsu University School of Medicine, Hamamatsu, Shizuoka, Japan) were enrolled. Patients were divided into two groups: those who developed post-operative delirium (Group D), and those who did not (Group ND). Pre-operative risk factors, including nutritional indices, for post-operative delirium were evaluated. ResultsGroup D comprised 16 participants, while Group ND comprised 273 participants. Comparisons between the two groups revealed significant differences in age, PNI, CONUT score, GNRI, and history of cerebrovascular disease. Multiple logistic regression analysis revealed that significant risk factors for delirium after TKA were age, PNI, and history of cerebrovascular disease. A receiver operating characteristic curve indicated that the cutoff values for delirium were 47.4 for PNI (sensitivity, 0.810; specificity, 0.875) and 78.5 years for age (sensitivity, 0.813; specificity, 0.722). ConclusionsRisk factors for post-operative delirium after TKA were PNI <47.4, age >78.5 years, and history of cerebrovascular disease. Patients exceeding these pre-operative cutoff values or with a history of cerebrovascular disease should receive counseling about delirium before surgery.

Pre-Infection Nutritional Status, Oxidative Stress, and One-Year-Long COVID Persistence in Patients Undergoing Hemodialysis: A Prospective Cohort Study.

Nutritional status's role in long COVID is evident in the general population, yet unexplored in patients undergoing hemodialysis (HD), posing a research gap. We hypothesized that pre-infection undernutrition in HD patients might impact long COVID persistence by accelerating oxidative stress. The present study aimed to investigate the association between pre-infection nutritional status, oxidative stress, and one-year-long COVID persistence in HD patients. This prospective observational cohort study enrolled 115 HD patients with confirmed COVID-19. Nutritional status was assessed using the Controlling Nutritional Status (CONUT) score twice: before infection and three months post-infection. Oxidative markers included malondialdehyde (MDAs), ceruloplasmin, transferrin, and sulfhydryl groups. The endpoint was one-year-long COVID persistence. Moderate pre-infection CONUT scores were associated with heightened severe undernutrition risk (p < 0.0001), elevated MDAs (p < 0.0001), and reduced ceruloplasmin levels (p = 0.0009) at three months post-COVID-19 compared to light CONUT scores. Pre-infection CONUT score independently predicted post-COVID oxidative damage [OR 2.3 (95% CI 1.2; 4.6), p < 0.0001] and one-year-long COVID persistence [HR 4.6 (95% CI 1.4; 9.9), p < 0.0001], even after adjusting for potential confounders. Moderate pre-infection undernutrition heightens post-COVID oxidative stress and increases the risk of one-year-long COVID persistence in HD patients.

Baseline 25(OH)D level is a prognostic indicator for bariatric surgery readmission: a matched retrospective cohort study.

Managing postsurgical complications is crucial in optimizing the outcomes of bariatric surgery, for which preoperative nutritional assessment is essential. In this study, we aimed to evaluate and validate the efficacy of vitamin D levels as an immunonutritional biomarker for bariatric surgery prognosis. This matched retrospective cohort study included adult patients who underwent bariatric surgery at a tertiary medical center in China between July 2021 and June 2022. Patients with insufficient and sufficient 25(OH)D (< 30 ng/mL) were matched in a 1:1 ratio. Follow-up records of readmission at 3 months, 6 months, and 1 year were obtained to identify prognostic indicators. A matched cohort of 452 patients with a mean age of 37.14 ± 9.25 years and involving 69.47% females was enrolled. Among them, 94.25 and 5.75% underwent sleeve gastrectomy and gastric bypass, respectively. Overall, 25 patients (5.54%) were readmitted during the 1-year follow-up. The prognostic nutritional index and controlling nutritional status scores calculated from inflammatory factors did not efficiently detect malnourishment. A low 25(OH)D level (3.58 [95% CI, 1.16-11.03]) and surgery season in summer or autumn (2.68 [95% CI, 1.05-6.83]) increased the risk of 1-year readmission in both the training and validation cohorts. The area under the receiver operating characteristic curve was 0.747 (95% CI, 0.640-0.855), with a positive clinical benefit in the decision curve analyses. The relationship between 25(OH)D and 6-month readmission was U-shaped. Serum 25(OH)D levels have prognostic significance in bariatric surgery readmission. Hence, preferable 25(OH)D levels are recommended for patients undergoing bariatric surgery.

Geriatric nutritional risk index and controller nutritional status score before metastatic first-line chemotherapy predict survival in patients over 70 years of age with metastatic bladder cancer.

Several prognostic factors have been identified in patients with metastatic bladder cancer (BC). As it is known, older adult patients are prone to nutritional deficiency. The knowledge about nutrition and impact on survival in older patients with metastatic bladder cancer is missing. It is necessary to specifically examine this population. Because timely interventions can make a positive impact on this patients population. This retrospective study aimed to evaluate the prognostic effect of the Geriatric Nutritional Risk Index (GNRI), Controller Nutritional Status (CONUT) score and Prognostic Nutritional Index (PNI) before first-line chemotherapy in the metastatic stage in patients with metastatic bladder cancer over 70. Patients over 70 with pathologically confirmed denovo metastatic or recurrent metastatic bladder cancer were included in the study. Patients with infections diagnosed at the time of diagnosis, autoimmune diseases or history of steroid use were excluded. Since our population consists of a specific age group with a specific cancer, we found a new cut-off value by performing ROC analysis to ensure optimal sensitivity and specificity in terms of progression. Low GNRI value was related with poor nutritional status. Low PNI value was related with poor nutritional status and high CONUT score was related with poor nutritional status. Factors predicting overall survival (OS) and Progression-Free Survival (PFS) were assessed using both univariate and multivariate Cox proportional hazards analyses. 106 patients were included in the study and the average age was 75.5 years. In the GNRI-Low group, PFS was significantly shorter than that in the GNRI-High group [HR (95% CI) = 57.1 (12.8-255.5), (p < 0.001)]. Among those with a low-CONUT score, PFS was found to be longer than that in the high-CONUT group [HR (95% CI) = 1.7 (1.0-3.0), (p = 0.039)]. The median PFS of the PNI-Low group wasn't significantly shorter than that of the PNI-High group [HR (95% CI) = 1.8 (0.5-6.2), (p = 0.359)]. Our study suggests that the GNRI and CONUT scores are useful for predicting survival in patients over 70 years of age with BC.

Impact of Controlling Nutritional Status Score on Mortality in Elderly Patients with Idiopathic Pulmonary Fibrosis.

Background: There are only a few reports on the nutritional status and mortality of patients with idiopathic pulmonary fibrosis (IPF). As such, this study aims to investigate the relationship between controlling nutritional status (CONUT) and the mortality of elderly patients with IPF. Methods: A total of 170 IPF patients aged ≥65 years old who visited the rehabilitation department of our hospital between July 2014 and July 2021 (mean age: 75.7 ± 6.3 years, sex (male/female): 138/32, %FVC: 78.3 ± 18.3%) were retrospectively analyzed. The Kaplan-Meier method and log-rank test were applied. Furthermore, using a Cox proportional hazards model with multivariate analysis, we analyzed the relationship between all-cause mortality and baseline characteristics including CONUT. Results: Based on the CONUT score, the normal group included 101 cases, the mild group included 58 cases, the moderate group included 11 cases, and the severe group had 0 cases. There were 49 cases of all-cause mortality events, suggesting that the mortality of the moderate group was significantly poorer than that of the normal and mild groups (p < 0.05). Furthermore, multivariate analysis identified GAP stage (HR: 5.972, 95%CI: 2.901~12.291, p < 0.0001), mMRC scale (HR: 0.615, 95%CI: 0.389~0.971, p = 0.009), and CONUT (HR: 2.012, 95%CI: 1.192~3.395, p = 0.037) as factors significantly influencing mortality. Conclusions: Severe malnutrition was not observed in elderly patients with IPF. Moderate malnutrition was associated with a significantly higher risk of all-cause mortality, suggesting that CONUT is an important indicator for predicting 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.

The efficacy of nutritional screening indexes in predicting the incidence of osteosarcopenia and major osteoporotic fracture in the elderly.

The effect of nutritional status on osteosarcopenia (OS) and major osteoporotic fracture (MOF) among the elderly is still unclear. So we aimed to compare the efficacy of the Mini-Nutrition Assessment-Short Form (MNA-sf), the Geriatric Nutritional Risk Index (GNRI) and Controlling Nutritional Status (CONUT) for predicting OS and MOF among the elderly. A total of 409 participants were enrolled in this prospective study. Blood biochemical indexes, nutritional status, and bone- and muscle-related examinations were assessed at initial visit to the outpatient. Participants were divided into 4 groups: (1) control; (2) osteopenia/osteoporosis; (3) sarcopenia; (4) osteosarcopenia, and then followed for 5years, recording the occurrence time of MOF. The frequency values of osteopenia/osteoporosis, sarcopenia, and OS, at baseline, were respectively 13.4, 16.1, and 12% among the study samples. Correlation analysis showed that nutritional status scores were associated with body mass index, handgrip strength, albumin, bone mineral density, and physical functions. According to multivariate models, poor nutritional status was significantly associated with a higher risk of OS and MOF (P<0.05). Survival analysis showed that the MOF rate in malnutrition group was significantly higher than normal nutrition group (P<0.05). The receiver operator characteristic curve shows that the value of MNA-sf to diagnose OS and MOF is greater (P<0.05). The poor nutritional status was associated with a higher risk of both OS and MOF. MNA-sf showed a superior diagnostic power for OS and MOF among the elderly. Early nutrition assessments and interventions may be key strategies to prevent OS and fractures.

Controlling the nutritional status score: a new tool for predicting postoperative mortality in patients with infrarenal abdominal aortic aneurysm treated with endovascular aneurysm repair.

AAA is a fatal condition that commonly occurs during vascular surgery. Nutritional status exerts a significant influence on the prognosis of various pathological conditions Scores from the CONUT screening tool have been shown to predict outcomes of certain malignancies and chronic diseases. However, the ramifications of nutritional status on AAA patients undergoing EVAR have not been elucidated in prior studies. In this study, we aimed to elucidate the correlation between CONUT scores and postoperative prognostic outcomes in patients with AAA undergoing EVAR. This was a retrospective review of 177 AAA patients treated with EVAR from June 2018 to November 2019 in a single center. Patient characteristics, CONUT scores, and postoperative status were collected. These patients were stratified into groups A and B according to CONUT scores. Subsequently, a comparative analysis of the baseline characteristics between the two cohorts was conducted. Cox proportional hazards and logistic regression analyses were employed to identify the autonomous predictors of mid-term mortality and complications, respectively. Compared with group A, patients in group B had higher midterm mortality (p < 0.001). Univariate analysis showed that CONUT scores; respiratory diseases; stent types; preoperative Hb, CRP, PT, and Fb levels were risk factors for death. Multivariate analysis confirmed that CONUT score [HR, 1.276; 95% CI, 1.029-1.584; p = 0.027] was an independent risk factor for mortality. Logistic regression analysis showed that prior arterial disease, smoking, and D-dimer levels were risk factors, although multivariate analysis showed smoking (OR, 3.492; 95% CI, 1.426-8.553; p = 0.006) was an independent risk factor. Kaplan-Meier curves showed that patients in group B had shorter mid-term survival than those in group A (log-rank p < 0.001). Malnutrition was strongly associated with mid-term mortality in patients with infrarenal AAA treated with EVAR.

Surgical interventions of colon cancer

Colon cancer is most common type of malignancies all over the world. Various risk factors including genetic mutations,old age,family history, smoking, drinking excessively, poor diet and several others are associated with increasing cases of colorectal carcinoma(CRC). Diagonosis is usually made by colonoscopy and and confirmed by tissue biopsy. After diagonosis delay to treatment can worsen the disease progression and long-term outcome.Treatment options for CRC include surgical resection either open or laparoscopic both with their merits and demerits. Laparoscopic resection have been well accepted for treatment and is known to result in less hospitalisation and blood loss while open surgery still has same overall survival rate, morbidity and mortality. Surgical treatment is associated with postoperative complications including port site metastases, surgical site infections (SSIs),Adhesions, intestinal obstruction, venous thromboembolic events, colonic ischemia, these complications can be decreased by preoperative assessment, intraoperative care and postoperative interventions. Controlling nutritional status (COUNT) score is prognostic factor of postoperative complications and mortality of patients with CRC. 5-years survival rate has increased upto 70% due to improved treatment modalities.

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

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. 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. 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). The combination of PMI and CONUT scores may be useful for predicting the prognosis of patients with PDAC after radical surgery.

The Relationship between Neutrophil-Lymphocyte Ratios with Nutritional Status, Risk of Nutritional Indices, Prognostic Nutritional Indices and Morbidity in Patients with Ischemic Stroke.

Background: In recent years, whole blood parameters and derivatives have been used as prognostic criteria in the course of various diseases. The aim of this study was to evaluate the relationship between parameters such as the neutrophil-lymphocyte ratio (NLR), the systemic immune-inflammation index (SII), the prognostic nutritional index (PNI), controlling nutritional status (CONUT) score, nutritional risk index (NRI) and immunonutrition status and disease activity in patients with ischemic stroke of the small-vessel, large-vessel and other etiologies. Methods: We retrospectively evaluated the records of 1454 consecutive ischemic stroke patients hospitalized in the emergency department of Gaziosmanpasa Education and Research Hospital from 2019 to 2023. Results: Of the 1350 patients with ischemic stroke included in the study, 58.8% had small-vessel disease, 29.3% had large-vessel disease and 11.9% had other etiologies. There was a significant difference between the three etiology groups for PNI and CONUT. The mean of PNI was 47.30 ± 8.06 in the other etiology group, 37.25 ± 7.23 in the small-vessel group, and 34.78 ± 8.16 in the large-vessel disease group. The mean of CONUT was 5.49 ± 1.20 in the small-vessel group, 5.12 ± 1.46 in the large-vessel group and 4.22 ± 1.11 in the other etiology group. In addition, CONUT and PNI were also found to be independent risk factors for mortality. A negative significant correlation was observed between PNI and NLR (r: -0.692), SII (r: -0.591), and CONUT (r: -0.511). Significant correlations were observed between CONUT and NLR (r: 0.402), SII (r: 0.312). Conclusions: PNI, CONUT and NRI were found as more accurate prognostic indicators of nutritional status in patients with ischemic stroke. NLR and SII may be important predictive markers in the course and prognosis of stroke.

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.

Prognosis of patients with coexisting obesity and malnutrition after ischemic stroke: A cohort study

BackgroundThe double burden of malnutrition, defined as the coexistence of obesity and malnutrition, is an increasing global health concern and is unclear in patients after ischemic stroke. The current study explored the combined impacts of obesity and malnutrition on patients with ischemic stroke. MethodsWe conducted a single-center prospective cohort study with patients with ischemic stroke enrolled in Minhang Hospital in China between January 2018 and December 2022. Patients were stratified into four categories based on their obesity (defined by body mass index) and nutritional status (classified according to the Controlling Nutritional Status score): (1) nourished nonobese; (2) malnourished nonobese; (3) nourished obese, and (4) malnourished obese. The primary end points were poor outcomes and all-cause mortality at 3 months. ResultsA total of 3160 participants with ischemic stroke were included in our study, of which 64.7% were male and the mean age was 69 years. Over 50% of patients were malnourished. At 3-month follow-up, the malnourished nonobese had the worst outcomes (34.4%), followed by the malnourished obese (33.2%), nourished nonobese (25.1%), and nourished obese (21.8%; P<0.001). In multivariable analyses, with nourished nonobese group as the reference, the malnourished nonobese group displayed poorer outcomes (odds ratio [OR], 1.395 [95% CI, 1.169–1.664]; P<0.001) and higher all-cause mortality (OR, 1.541 [95% CI, 1.054-2.253], P=0.026), but only a nonsignificant increase in poor prognosis rate (33.2% vs. 25.1%, P=0.102) and mortality (4.2% vs. 3.6%, P=0.902) were observed in the malnourished obese group. ConclusionA high prevalence of malnutrition is observed in the large population suffering from ischemic attack, even in the obese. Malnourished patients have the worst prognosis particularly in those with severe nutritional status regardless of obesity, while the best functional outcomes and the lowest mortality are demonstrated in nourished obese participants.
