AI Article Synopsis
- There is a lack of research on the role of cytokines in lung issues among children with rheumatic diseases (RD), prompting this investigation.
- Blood levels of 12 cytokines were analyzed in newly diagnosed RD patients to determine their relationship with lung involvement, utilizing high-resolution computed tomography (HRCT) and pulmonary function tests (PFTs).
- The results indicated that IL-6 and IFN-γ levels were significantly higher in RD patients with lung involvement compared to those without and the control group, suggesting these cytokines could play a key role in the lung complications of RD.
Article Abstract
Background: There was less research about cytokines in lung involvement of childhood-onset rheumatic diseases (RD) patients.
Objective: In this investigation, blood levels of 12 cytokines were tested in order to explore their associations with lung involvement in newly diagnosed childhood-onset RD patients.
Methods: High-resolution computed tomography (HRCT) and pulmonary function tests (PFTs) were performed on 53 newly diagnosed RD patients without any treatment in our department between July 2021 and December 2023. Patients were separated into groups based on whether their lungs were involved or not according to abnormalities found on HRCT or PFTs. We examined the serum cytokines with 41 healthy, age and gender-matched controls.
Results: The majority of serum cytokine levels were statistically different between the RD group with lung involvement and the control group. The RD group with lung involvement had considerably higher serum IL-6 and IFN-γ levels than the RD group without lung involvement or control group. The median serum IL-6 levels were 19 pg/ml [interquartile range (IQR) 6.9, 27.6], 4.4 pg/ml (IQR 2.0, 10.5), and 2.0 pg/ml (IQR 2.0, 2.0) in RD group with lung involvement, RD group without lung involvement, and control group, respectively. Similarly, the median serum IFN-γ levels were 6.0 pg/ml (IQR 5.0, 15), 5.0 pg/ml (IQR 5.0, 5.0), and 5.0 pg/ml (IQR 5.0, 5.0) in RD group with lung involvement, RD group without lung involvement, and control group, respectively. The receiver operating characteristic (ROC) curve study showed that IL-6 and IFN- had area under the curve (AUC) values of 0.782 and 0.742, respectively, indicating their significant diagnostic potential for lung involvement in RD patients.
Conclusion: Our findings imply that IL-6 and IFN-γ may be associated with the development of lung illnesses and may be involved in the pathophysiology of RD. Thus, in individuals with RD, elevated levels of IFN- over 5.42 pg/ml or IL-6 above 6.25 pg/ml may warrant suspicion of lung involvement.

This study aims to review the literature and estimate the global pooled prevalence of interstitial lung disease among patients with rheumatoid arthritis (RA-ILD). The influence of risk factors like geography, socioeconomic status, smoking and DMARD use will be explored. A systematic review was performed according to the PRISMA and JBI guidelines.

Background: Despite the physiological advantages of positive end-expiratory pressure (PEEP), its optimal utilization during one-lung ventilation (OLV) remains uncertain. We aimed to investigate whether individualized PEEP titration by lung compliance is associated with a reduced risk of postoperative pulmonary complications during OLV.
Methods: We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials until April 1, 2024, to identify published randomized controlled trials that compared individualized PEEP titration by lung compliance with fixed PEEP during OLV.

Background: Several studies have suggested that lung tissue heterogeneity is associated with overall survival (OS) in lung cancer. However, the quantitative relationship between the two remains unknown. The purpose of this study is to investigate the prognostic value of whole lung-based and tumor-based radiomics for OS in LA-NSCLC treated with definitive radiotherapy.

Background: Sepsis is a systemic inflammatory syndrome that can cause coagulation abnormalities, leading to damage in multiple organs. Vascular endothelial cells (VECs) are crucial in the development of sepsis-induced coagulopathy (SIC). The role of Parthenolide (PTL) in regulating SIC by protecting VECs remains unclear.

The REAADS VWF activity assay is often assumed to be specific for the A1 domain, the portion of VWF that binds platelet GPIbα. We tested this assay on the A1A2A3 region of VWF with each domain expressed independently of one another and together in combination as a tri-domain. The monoclonal antibody used in this assay is found to be insensitive to the single A domains and does not recognize free A1 domains as it is often assumed.
