AI Article Synopsis

  • The study aimed to explore the link between systemic inflammation, monocyte counts, and resting state functional connectivity (rsFC) in older patients undergoing surgery.
  • A secondary analysis of fMRI scans and blood markers was conducted before and three months after surgery, looking for correlations using regression models.
  • Results showed no significant connections between inflammation markers or blood cell counts and rsFC across various networks, highlighting a contrast with previous studies and suggesting that longitudinal measurements can help reduce false positive findings in neuroimaging research.

Article Abstract

Objective: Systemic inflammation and monocyte counts have previously been associated with changes in resting state functional connectivity (rsFC) in cross-sectional neuroimaging studies. We therefore investigated this association in a longitudinal study of older patients.

Methods: We performed a secondary analysis of longitudinal data from older patients who underwent functional magnet resonance imaging (fMRI) scans before and 3 months after elective surgery. Additionally, serum levels of C-reactive protein and Interleukin-6 as markers of inflammation and leukocyte, lymphocyte and monocyte counts were determined. Correlations between these markers and pre- or postoperative rsFC between regions previously associated with inflammatory markers were investigated using general linear regression models.

Results: We found no significant correlations between inflammatory markers or blood cell counts and mean connectivity within four resting state networks (RSNs), neither preoperatively nor postoperatively. Significant inter-region rsFC was found within these RSNs between a few regions either pre- or postoperatively, but no inter-region connections were consistently observed in both pre- and postoperative fMRI scans.

Conclusions: Inflammatory markers and monocyte counts were not associated with rsFC in our study, contrasting previous results.

Significance: Multiple measurements in the same individuals, as performed here, provide a way to reduce the high risk of false positive results in fMRI studies.

Background: This study aims to explore the interplay between body mass index (BMI), neutrophils, triglyceride levels, and uric acid (UA). Understanding the causal correlation between UA and health indicators, specifically its association with the body's inflammatory conditions, is crucial for preventing and managing various diseases.

Methods: A retrospective analysis was conducted on 4,286 cases utilizing the Spearman correlation method.

Aims/hypothesis: Within the small intestine, neutrophils play an integral role in preventing bacterial infection. Upon interaction with bacteria or bacteria-derived antigens, neutrophils initiate a multi-staged response of which the terminal stage is NETosis, formation of protease-decorated nuclear DNA into extracellular traps. NETosis has a great propensity to elicit ocular damage and has been associated with diabetic retinopathy and diabetic macular oedema (DME) progression.

Background: Obesity plays a crucial role in the development of metabolic disorders including diabetes, coronary and renal diseases. There are several factors involved in the pathology of obesity, including chronic inflammation and exposure to environmental contaminants. Recently, the cholinergic co-hydrolyzing enzyme BChE has been associated with clinical conditions such as diabetes and obesity.

Growing evidences have suggested the airway microbiota may participate in lung cancer progression. However, little was known about the relationship between airway microbiota and lung cancer associated systemic inflammation. Here we aimed to explore the association between sputum microbiota and systemic inflammation in lung cancer.
