Classification of Histologically Proven Inflammation in Clinically Inactive Corneal Scars: Implications for Graft Outcomes After Penetrating Keratoplasty.

: Clinically inactive corneal scars have repeatedly been shown to exhibit histological inflammation. This study aimed to evaluate the degree of histological inflammation in clinically inactive corneal scars of different origins and its correlation with graft rejection and failure following penetrating keratoplasty. : The study included 205 primary corneal explants with clinically inactive central scars resulting from herpes simplex virus keratitis (HSV, = 55), keratoconus ( = 39), mechanical trauma ( = 27), scrophulosa ( = 22) or other/unknown causes ( = 62).

Invasive mechanical ventilation strategies, adjuvants treatments and adverse events among ICU patients with COVID-19 in Denmark.

Aim: To describe the use of invasive mechanical ventilation core strategies, adjuvant treatments and the occurrence of barotrauma and prolonged ventilation in ICU patients with COVID-19 in Denmark, retrospectively.

Methods: All ICUs admitting COVID-19 patients in Denmark from 10 March 2020 to 2 April 2021 were invited to participate. All patients with COVID-19 who received invasive mechanical ventilation were included and data was retrospectively collected from electronic patient records.

BlephEx-treatment for blepharitis: a prospective randomized placebo-controlled trial.

Background: Blepharitis is a chronic inflammatory condition of the eyelids that affects a large proportion of patients in eye care settings. First-line treatments provide only partial relief for many patients. The BlephEx™ device provides automated eyelid debridement and aims to remove pathogenic biofilms from the eyelid margin to treat blepharitis long-term.

Domestic groundwater wells in Appalachia show evidence of low-dose, complex mixtures of legacy pollutants.

Lack of water quality data for private drinking water sources prevents robust evaluation of exposure risk for communities co-located with historically contaminated sites and ongoing industrial activity. Areas of the Appalachian region of the United States (, Pennsylvania, Ohio and West Virginia) contain extensive hydraulic fracturing activity, as well as other extractive and industrial technologies, in close proximity to communities reliant on private drinking water sources, creating concern over potential groundwater contamination. In this study, we characterized volatile organic compound (VOC) occurrence at 307 private groundwater well sites within Pennsylvania, Ohio, and West Virginia.

The effect of charge screening for cationic surfactants on the rigidity of interfacial nanoparticle assemblies.

Hypothesis: Functionalizing colloidal particles with oppositely charged surfactants is crucial for stabilizing emulsions, foams, all-liquid structures, and bijels. However, surfactants can reduce the attachment energy, the driving force for colloidal self-assembly at interfaces. An open question remains on how the inherent interfacial activity of cationic surfactants influences the interfacial rigidity of particle-laden interfaces.
