Article Abstract

A unique measure of inflammatory evaluation, the systemic inflammation response index (SIRI) may offer useful data for the diagnosis and risk assessment of a number of diseases. The aim of this study was to investigate the relationship between SIRI and femur bone mineral density (BMD) in US adults. The association between SIRI and femur BMD was examined using multivariate logistic regression, sensitivity analysis, and smoothing curve fitting using data from the National Health and Nutrition Examination Survey (NHANES) 2005-2010, 2013-2014, and 2017-2018. Subgroup analysis and interaction tests were employed to examine the population-level stability of this connection. This present study included 18,022 participants older than 20 years from NHANES (2005-2010, 2013-2014, and 2017-2018). The present study showed a negative association between SIRI and femur BMD (including total femur BMD, femoral neck BMD, trochanter BMD, and intertrochanter BMD). In the fully adjusted model, we found a negative association between the SIRI and total femur BMD (Beta = -0.0032, 95% CI: -0.0053 to -0.0012), a negative association between the SIRI and femoral neck BMD (Beta = -0.0025, 95% CI: -0.0045 to -0.0005), a negative association between the SIRI and trochanter BMD (Beta = -0.0032, 95% CI: -0.0050 to -0.0013), a negative association between the SIRI and intertrochanter BMD (Beta = -0.0031, 95% CI: -0.0056 to -0.0007). This negative association was more pronounced in older adults > 65 years of age. In addition, we found a U-shaped association between SIRI and femur BMD by further smoothing curve-fitting methods. SIRI was negatively associated with femur BMD in US adults, and this association was more significant in older adults over 65 years. SIRI may be a useful, convenient, and practical indicator of inflammation. Moreover, older adults with high SIRI levels are likely to have low femur BMD.

Rheumatoid arthritis (RA) is an autoimmune condition characterized by widespread and persistent inflammation. In this study, we sought to investigate the association between the systemic inflammation response index (SIRI) and the likelihood of RA occurrence among individuals in the United States. This study conducted a retrospective analysis using data collected from the National Health and Nutrition Examination Survey from 1999 to 2020.

TP53 mutations are highly associated with hepatocellular carcinoma (HCC), a common and deadly cancer. However, few primary drivers in the progression of HCC with mutant TP53 have been identified. To uncover tumor suppressors in human HCC, a genome-wide CRISPR/Cas9-based screening of primary human hepatocytes with MYC and TP53 overexpression (MT-PHHs) is performed in xenografts.

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.

Objective: Large hemispheric infarction (LHI) represents one of the most severe subtypes of ischemic stroke, associated with high rates of disability and mortality. This study aimed to examine the association between the systemic inflammation response index (SIRI) and LHI, identify independent risk factors, and develop a predictive model for clinical application.

Methods: A total of 152 patients diagnosed with LHI and admitted to Shaanxi Provincial People's Hospital between June 2020 and June 2023 were retrospectively selected based on defined inclusion and exclusion criteria.

Background: Inflammation and hyperuricemia are closely associated with chronic kidney disease (CKD). The systemic inflammation response index (SIRI), systemic immune-inflammation index (SII), monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) are emerging as novel biomarkers. While, the synergistic effects of these biomarkers with hyperuricemia on CKD remain unclear.
