Aims: The prognosis of colorectal cancer (CRC) has been historically reliant on the Tumor Node Metastasis (TNM) staging system, but there is variability in outcomes among patients at similar stages. Therefore, there is an urgent need for more robust biomarkers. The aim of this study was to assess the clinical feasibility of the recently reported Inflammatory Burden Index (IBI) for predicting short- and long-term outcomes in patients with CRC.
Methods: This was a retrospective observational study of 555 CRC patients undergoing surgery for primary tumor resection. We determined the prognostic value of preoperative IBI for disease-free and overall survival, and its predictive value for perioperative risk of infectious complications, including surgical site infection.
Results: Increased preoperative IBI was significantly associated with advanced disease stage and poor oncological outcome in CRC patients. Higher IBI was independently linked to poorer disease-free and overall survival. Similar outcomes were observed in a subanalysis focused on high-risk stage II and stage III CRC patients. Elevated preoperative IBI was significantly correlated with an increased risk of surgical site infection and other postoperative infectious complications. Propensity score-matching analysis validated the impact of IBI on the prognosis in CRC patients.
Conclusion: We established preoperative IBI as a valuable predictive biomarker for perioperative risks and oncological outcomes in CRC patients. Preoperative IBI is useful for designing effective perioperative management and postoperative oncological follow-up.

Background: The Inflammatory burden Index (IBI) is an effective predictor for a range of malignancies. However, the significance of IBI in esophageal squamous cell carcinoma (ESCC) needs to be further verified. The aim of this study was to verify the predictive power of IBI in ESCC undergoing radical resection.

Purpose: Preoperative albumin to alkaline phosphatase ratio (AAPR) and inflammatory burden index (IBI) are prognostic indicators for a multitude of cancers, and our study focuses on evaluating the prognostic significance of the AAPR and the IBI on rectal cancer (RC) patients to provide a more accurate guideline for patient prognosis.
Patients And Methods: This study enrolled patients who underwent laparoscopic rectal cancer surgery from January 2016 to January 2021. We utilized three machine learning approaches to select variables most relevant to prognosis in the training cohort.
Noninvasive Assessment of Temporal Dynamics in Sympathetic and Parasympathetic Baroreflex Responses.

Article Synopsis
- The study focuses on the baroreflex system, crucial for regulating blood pressure and heart function, by developing a noninvasive method to assess its sympathetic and parasympathetic branches simultaneously.
- Researchers analyzed data from cardiothoracic surgery patients and other subjects to estimate key cardiovascular parameters and calculate baroreflex sensitivity (BRS) using pulse contour analysis and a sequence method.
- Results showed that parasympathetic BRS for heart rate was linked to heart rate variability metrics, while sympathetic BRS was associated with blood pressure, cardiac output, and heart rate variability under different conditions, suggesting nuanced autonomic responses to postural changes.

Article Synopsis
- The study assessed the Inflammatory Burden Index (IBI) as a potential prognostic marker for gastric cancer (GC) patients undergoing gastrectomy, highlighting its relationship with patient outcomes.
- Researchers analyzed data from 459 patients treated at the Kanagawa Cancer Center, finding that those with a high IBI had lower overall survival and recurrence-free survival rates compared to those with a low IBI.
- The findings suggest that a high preoperative IBI is an independent predictor of poor prognosis, indicating its potential utility in clinical decision-making for GC treatment.
