Background: The pathologic consequences of inflammatory responses in chronic cerebrospinal venous insufficiency (CCSVI) remains poorly understood. Hence, this study was aimed to evaluate the peripheral inflammatory biomarkers in patients with intracranial and extracranial CCSVI pathology. In addition, the relationship between inflammatory cytokine profile and CCSVI prognosis was also evaluated.
Methods: Patients diagnosed with CCSVI between July 2017 and July 2019 were included and subsequently divided into 3 groups based on the location of stenosis. The inflammatory biomarker assay included neutrophil-to-lymphocyte ratios (NLRs), platelet-to-lymphocyte ratios (PLRs), red blood cell distribution widths (RDW), C-reactive protein (CRP) levels, interleukin-6 (IL-6) levels, and neuron-specific enolase levels. Clinical outcomes were assessed using the modified Rankin Scale and Patient Global Impression of Change score. Univariate and multivariate regression analyses were performed to identify significant prognostic factors for poorer outcomes. Finally, we established a nomogram based on the multivariate regression analysis.
Results: We enrolled 248 patients in total, including 102 males and 146 females, with an average age of 57.85±12.28 years. Compared with patients with internal jugular vein stenosis, cerebral venous sinus stenosis (CVSS) patients were mostly younger and had been suffering from headaches and severe papilledema. Higher levels of NLR, RDW, and CRP were also observed in the CVSS group. Multivariate analysis indicated that NLR, PLR, and IL-6 were the independent prognostic factors for poor CCSVI outcomes.
Conclusions: The clinical presentations and increases in NLR, PLR, IL-6, and CRP levels could be distinctly marked in patients with CVSS-related CCSVI than that in internal jugular vein stenosis-related CCSVI, indicating poor prognostic outcomes in these patients. A proinflammatory state might be associated with CCSVI pathology.

Neurodegenerative diseases (NDs) are caused by progressive neuronal death and cognitive decline. Epigallocatechin 3-gallate (EGCG) is a polyphenolic molecule in green tea as a neuroprotective agent. This review evaluates the therapeutic effects of EGCG and explores the molecular mechanisms that show its neuroprotective properties.

Complex regional pain syndrome (CRPS) is a severe pain disorder with an unclear pathophysiology. Biomarkers offer opportunities to enhance diagnosis, stratification, prognosis, and monitoring. Serum markers such as cytokines and microRNAs show potential but require further research.

Purpose Of Review: To highlight advancements in managing traditional and rheumatoid arthritis (RA) specific risk factors and the impact of RA treatments on cardiovascular outcomes.
Recent Findings: Advancements in rheumatoid arthritis management have paralleled declining trends in cardiovascular disease risks. Biomarkers like CRP, Lipoprotein(a), Apolipoprotein B 100, and imaging tools such as coronary artery calcium scoring enhance cardiovascular risk stratification, particularly in intermediate-risk RA patients.

The present study aimed to assess the capability of biomarkers, including inflammatory indicators, anaemic markers, lipid markers, and renal function indices, to differentiate between different stages of chronic kidney disease (CKD). Expected to provide a new strategy for monitoring the development of CKD and stratified treatment management, providing valuable insights for future biomarker studies to explore early detection of CKD. The changes in inflammatory markers (interferon gamma [IFN-γ], interleukin [IL]-17A, IL-10, IL-6, IL-4, IL-2, IL-1 and white blood cells [WBC]), lipid markers (high-density lipoprotein cholesterol [HDL-c], low-density lipoprotein cholesterol [LDL-c], and triglyceride [TG]), indicators of kidney injury (serum creatinine [Scr] and blood urea nitrogen [BUN]) in 451 patients with different stages of CKD were examined.

Background: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) particularly when coupled with acute respiratory failure (ARF), markedly elevates mortality rates. This investigation focuses on pivotal inflammatory markers in exacerbations of chronic obstructive pulmonary disease (COPD), including the neutrophil-to-lymphocyte ratio (NLR), lactate-to-albumin ratio (LAR), glucose-to-lymphocyte ratio (GLR), prognostic nutritional index (PNI), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII), which are easily determinable from peripheral blood. We aimed to investigate the prognostic value of NLR, LAR, GLR, SII, PNI, and PLR for in-hospital mortality among AECOPD patients with ARF.
