Objective: This study investigated the relationship between potential prognostic parameters that may be associated with increased inflammation and survival in patients with malignant mesothelioma (MM).
Methods: This retrospective study assessed potential prognostic parameters measured at the time of MM diagnosis. Data on asbestos exposure, histopathological subtype of MM and laboratory parameters were collected.
Results: In 155 patients with MM (90 male), mean survival time was 13.9 months. In univariate analysis, age ≥ 60 years and neutrophil-to-lymphocyte ratio (NLR) ≥ 3 were associated with significantly shortened median survival times. In multivariate analysis, nonepithelial subtype, red cell distribution width (RDW) ≥ 20% and NLR ≥ 3 were associated with significantly shortened median survival times. Mortality rate was increased 2.77-, 1.67- and 1.52-fold in patients with RDW ≥ 20%, NLR ≥ 3 and nonepithelial subtype, respectively. Nonepithelial subtype, white blood cell count ≥ 11 200 µl and platelet-to-lymphocyte ratio ≥ 300 at baseline were associated with a heightened NLR value.
Conclusions: The NLR and RDW were significant predictive factors for MM prognosis.

CircHipk3 serves a dual role in macrophage pyroptosis by promoting NLRP3 transcription and inhibition of autophagy to induce abdominal aortic aneurysm formation.

Aims: CircRNAs could regulate macrophage pyroptosis, which has the potential in promoting the synergistic effect of inflammation and matrix metalloproteinase (MMP) activity in abdominal aortic aneurysm (AAA). But the roles of circRNAs in modulating macrophage pyroptosis in the AAA remain unknown. This study explored the contribution to AAA of circHipk3, which was macrophage pyroptosis promoter, and the underlying mechanism.

Aim: Our previous study has found a differential microbial metabolite in atherosclerosis (AS) mice, aminoadipic acid (AAA), which was considered as a potential harmful metabolite. However, whether it can promote AS vascular inflammation and its mechanisms remain unclear. Paeonol (Pae) plays an anti-AS role by regulating the metabolic profile, but whether Pae exerts its antiatherogenic effect by reducing serum AAA levels is unknown.

: One of the important postoperative complications of endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) is type 2 endoleak (T2EL). However, there is no well-established biomarker. We aimed to evaluate the validity of the neutrophil-lymphocyte ratio (NLR) as a predictor of T2EL.

Background And Aims: Activation of the systemic inflammatory response (SIR) is associated with inferior outcomes across a spectrum of disease. Routinely available measures of the SIR (neutrophil:lymphocyte ratio (NLR), platelet:lymphocyte ratio (PLR), systemic immune-inflammatory index (SII), systemic inflammatory grade (SIG)) have been shown to provide prognostic value in patients undergoing surgical intervention. The present study aimed to review the literature describing the prognostic association of NLR, PLR, SII and SIG in patients undergoing intervention for abdominal aortic aneurysm (AAA).

Background: Clinically useful predictors for risk stratification of long-term survival may assist in selecting patients for endovascular abdominal aortic aneurysm (EVAR) procedures. This study aimed to analyze the prognostic significance of peroperative novel systemic inflammatory markers (SIMs), including the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), hemoglobin-to-red cell distribution width ratio (HRR), systemic immune-inflammatory index (SIII), and systemic inflammatory response index (SIRI), for long-term mortality in EVAR.
Methods: A retrospective analysis was performed on 147 consecutive patients who underwent their first EVAR procedure at the Department of Vascular Surgery, Beijing Hospital.
