Objective: The aim of present study was to assess the predictive value of the admission prognostic nutrition index (PNI), controlling nutritional status (CONUT) associated with delayed cerebral ischemia (DCI), and 3-month neurological outcomes after aneurysmal subarachnoid hemorrhage (aSAH).
Methods: The clinical data from 252 patients with aSAH were retrospectively analyzed. Receiver operating characteristic analysis was performed to assess the predictive ability of the PNI and CONUT score and identify the cutoff point. Multivariate analysis was conducted to assess the role of the PNI and CONUT score in predicting for DCI and outcomes at 3 months after aSAH treatment.
Results: We enrolled 252 patients with aSAH in our study. Of the 252 patients, 53 experienced DCI and 57 patients had a poor outcome. Patients with unfavorable outcomes had a lower serum albumin, lymphocyte count, total cholesterol, and PNI but a high CONUT score, Hunt-Hess grade, and aneurysm size (P < 0.05). Both the PNI and CONUT score correlated with the Hunt-Hess grade (r = -0.289 and P < 0.001; r = 0.512 and P < 0.001), modified Rankin scale score at 3 months (r = -0386 and P < 0.001; r = 0.533 and P < 0.001), aneurysm size (r = -0.219 and P < 0.001; r = 0.422 and P < 0.001). Only a CONUT score <4 (odds ratio, 0.241; 95% confidence interval, 0.071-0.842; P = 0.022) independently predicted the functional outcome status but not DCI at 3 months after aSAH. However, PNI was an unrelated factor associated with DCI and the clinical outcome.
Conclusions: Our results have indicated that the CONUT score might efficiently predict for the clinical outcomes at 3 month after aSAH.

Association of Immune Nutrition Indices with the Risk of All-Cause Mortality and Cardiovascular Mortality in Patients with Heart Failure in the NHANES (1999-2018).

Background: Heart failure (HF) remains a global challenge with disappointing long-term outcomes. Malnutrition is prevalent in patients with HF and disrupts the equilibrium of immune and inflammatory responses, resulting in further deterioration of the HF. Novel indicators emerge as immune nutrition indices, including the prognostic nutritional index (PNI), neutrophil-to-lymphocyte ratio (NLR), Controlling Nutritional Status (CONUT) score, and cholesterol-modified prognostic nutritional index (CPNI).

Purpose: Multiple inflammatory and nutritional biomarkers have been established as independent prognostic factors across various solid tumors, but their role in outcomes prediction for glioma is still under investigation. Aim of the present systematic review is to report the available evidence regarding the impact of nutritional assessment and intervention for glioma prognosis and patients' quality of life (QoL).
Materials And Methods: Our systematic review conformed to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines.
Low skeletal muscle mass as a proxy marker of sarcopenia is a risk factor for major complications in older patients undergoing curative colon resections for colon cancer.

Introduction: Various reports have confirmed that low skeletal muscle mass, a proxy marker of sarcopenia, can be a risk factor for surgical and oncological outcomes in colon cancer. We aimed to investigate the effects of skeletal muscle mass index (SMMI) on postoperative complications, overall survival (OS), and disease-free survival (DFS) in older patients with colon cancer who underwent elective curative colon resections.
Materials And Methods: Patients over 65 years old with stage I-III colon cancer who underwent elective curative colon resections between January 2015 and December 2023 were included in this single-center retrospective longitudinal study.
Erythrocyte modified controlling nutritional status as a biomarker for predicting poor prognosis in post-surgery breast cancer patients.

Nutrition and inflammation are closely related to prognosis in breast cancer patients. However, current nutritional and inflammatory measures predict disease free survival (DFS) of breast cancer are still different, and the most predictive measures remain unknown. This study aimed to compare the predictive effects of commonly used nutritional and inflammatory measures on DFS and to improve existing nutritional or inflammatory measures in order to develop a new model that is more effective for predicting postoperative recurrence and metastasis in breast cancer patients.

Background: Esophagojejunal anastomotic fistula (EJF) following radical total gastrectomy is a severe perioperative complication in patients with gastric cancer, particularly as delayed fistula healing increases hospitalization costs and leads to poor prognosis. Numerous factors influence the occurrence and progression of EJF, with inflammation and nutritional status being significant contributors to perioperative complications. Therefore, this study aims to investigate the prediction of delayed EJF healing based on postoperative clinical and imaging-related inflammation-nutrition status.
