Repeatability of lipid layer thickness using LipiView® following removal of contact lenses and its relationship to comfort.

Purpose: To assess the repeatability of lipid layer thickness (LLT) measurement using the LipiView® interferometer after daily disposable contact lens (CL) wear and correlation with ocular comfort in soft contact lens wearers.

Methods: A prospective study was conducted over two consecutive months, wherein CL wearers (n = 20) wore either Somofilcon A or Verofilcon A daily disposable CLs in a crossover design, switching lenses after 1 month. The pre-corneal tear film LLT was measured at the end of each month after CLs had been worn for at least 6 h.

Dietary amino acids intake and all-cause and cause-specific mortality: results from the Golestan Cohort Study.

Background: Less is known whether the amino acid composition of dietary protein sources effects on long-term health outcomes. We aimed to evaluate the association between dietary amino acid composition and all-cause and cause-specific mortality.

Methods: This study used data from the Golestan Cohort Study, which was performed in the Golestan Province of Iran from January 2004 to June 2008.

Meibomian Gland Shortening Is Associated With Altered Meibum Composition.

Purpose: The purpose of this study was to investigate differences in the composition of meibum extracted from human meibomian glands displaying different morphological characteristics.

Methods: Adult participants with evidence of meibomian gland shortening were enrolled. Glands were observed using infrared meibography, and meibum was collected from one short and one long gland from the lower eyelid of the same eye.

Baseline socioeconomic status predicting post-COVID-19 symptoms: Results from Isfahan COVID Cohort (ICC) study.

Objectives: Patients experience complications following their recovery from COVID-19, known as post-COVID-19. This study aimed to investigate the association between baseline socioeconomic status (SES) and post-COVID-19 symptoms among hospitalized and non-hospitalized patients.

Methods: In the study, we used data from the Isfahan COVID Cohort (ICC) study, a 5-year longitudinal cohort study started from March 10, 2020.

A simulation study on the effect of penetration of gold nanoparticles in the cytoplasm of healthy eye organs on dose enhancement of brachytherapy.

Purpose: Special properties and recent advances in the synthesis and biomolecular functionalization of gold nanoparticles (GNPs) have led to the evolution of their use in biomedical applications such as photon radiotherapy. Simulation-based studies on the effect of various parameters that govern the dose enhancement due to utilizing GNPs have facilitated the progress of knowledge in this field. Due to their flexibility and easier accessibility compared with experimental works, simulations have the potential to be considered for pre-clinical tests and, therefore, should be close to the realistic conditions as much as possible.
