Chronic ocular pain impacts quality of life and is often linked to ocular surgery. We assessed the prevalence of chronic postoperative pain (CPOP) after cataract surgery and associated risk factors using a secondary cohort post-hoc analysis of data from the Age-Related Eye Disease Study (AREDS), a multicenter, controlled, randomized clinical trial of antioxidant vitamins and minerals. Ocular pain was determined from item 4 of the National Eye Institute Visual Function Questionnaire (NEI-VFQ-25), administered between 1997 and 2005.

Purpose: The corneal nerves within the sub-basal nerve plexus (SBNP) display a distinctive whorl-like pattern, a highly dynamic structure that could be a marker of diseases. Previous studies have reported a decrease in whorl nerve density in patients with diabetes, indicating an avenue for noninvasive monitoring of diabetic neuropathy. However, conflicting results have since been reported, highlighting the need for improved quantitative analysis of the corneal whorl.

Article Synopsis
  • - This study focused on community-acquired pneumonia (CAP) in children, aiming to identify mucosal biomarkers that can aid in determining the severity and cause of the illness.
  • - Researchers analyzed cytokine levels in nasopharyngeal samples from 182 children with CAP and 26 healthy controls, finding that those with atypical bacteria and influenza virus had significantly elevated cytokine concentrations compared to those with typical bacteria.
  • - The findings suggest that differences in inflammatory and antiviral cytokine levels correlate with disease severity in CAP, indicating that mucosal biomarkers might be helpful for better assessing and classifying the condition in pediatric patients.

Liver fibrosis develops in response to chronic liver injury and is characterized by a sustained inflammatory response that leads to excessive collagen deposition by myofibroblasts. The fibrogenic response is governed by the release of inflammatory mediators from innate, adaptive, and innate-like lymphoid cells and from nonprofessional immune cells (i.e.
