Article Abstract
Objectives: To establish a novel Inflammation Prognostic Score Index (IPSI) and evaluate its prognostic value and complementary role to the International Staging System (ISS) in newly diagnosed multiple myeloma (MM).
Methods: This retrospective study analyzed 98 newly diagnosed MM patients. ROC-derived cutoffs stratified patients by RDW, PLT, NMLR, SII, and SIRI. The IPSI was constructed by assigning 1 point each to elevated RDW, low PLT, and high NMLR, defining three risk groups: 0-1, 2, and 3 risk factor groups. Survival and ISS correlations were evaluated using Kaplan-Meier, Cox, and Spearman's tests.
Results: Multivariate analysis confirmed RDW, PLT, and NMLR as independent predictors of overall survival (OS) (all < 0.05). Based on these, IPSI stratified patients into three risk groups: 0-1, 2, and 3 risk factor groups, with median OS of 24, 21.5, and 14 months, respectively (log-rank < 0.001). IPSI was an independent prognostic factor (2-risk-factors group: HR = 8.74; 3-risk-factors group: HR = 18.98 vs 0-1-risk-factors group; both < 0.001) and correlated with ISS stage ( = 0.35, < 0.001). Critically, IPSI refined risk stratification within all ISS subgroups ( < 0.001). SII and SIRI correlated with ISS but were not independent prognostic factors.
Conclusions: As an independent prognostic index that integrates RDW, PLT, and NMLR, IPSI optimizes ISS staging and provides a cost-effective risk stratification tool. It may be a good measure indice of identifying high-risk MM patients in resource constraint setting where access to molecular testing is not available.

Rationale: Inflammation is central to chronic obstructive pulmonary disease (COPD) pathogenesis but incompletely represented in COPD prognostic models. Neutrophil to lymphocyte ratio (NLR) is a readily available inflammatory biomarker.
Objectives: To explore the associations of NLR with smoking status, clinical features of COPD, and future adverse outcomes.

Background: Liver cirrhosis, characterized by chronic inflammation, is frequently complicated by malnutrition. Nutritional indices, such as the prognostic nutritional index (PNI) and the skeletal muscle index (SMI), calculated as the muscle area quantified via CT scans at the third lumbar vertebra level divided by the square of the patient's height in meters (cm/m), are associated with outcomes in inflammatory diseases.
Objectives: We aimed to evaluate the diagnostic efficacy of the PNI both independently and in combination with the SMI for identifying malnutrition in cirrhosis and to explore their prognostic implications.

Objective: This study aims to investigate the relation of inflammatory markers to the long-term prognosis of patients with severe non-ST-segment elevation myocardial infarction (NSTEMI) in the intensive care unit (ICU), and to further develop a predictive model for their long-term outcomes.
Methods: This study utilized data on eligible NSTEMI patients from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. Patients were grouped based on mortality outcomes.

Background: Systemic immune-inflammatory index (SII) and prognostic nutritional index (PNI) are known to predict the severity and prognosis of various diseases. However, their role in sudden sensorineural hearing loss (SSNHL) is unclear.
Methods: This study collected 100 patients with SSNHL and 100 healthy volunteers.

Objectives: To study the impact of SURF4 expression level on long-term prognosis of gastric cancer (GC) and biological behaviors of GC cells.
Methods: SURF4 expression level in GC and its association with long-term patient prognosis were analyzed using publicly available databases and in 155 GC patients with low and high SURF4 expressions detected immunohistochemically. The Cox proportional hazard model and Kaplan-Meier survival curves were used to analyze independent prognostic predictors of GC and the 5-year survival rate of the patients with different SURF4 expression levels.
