Lifitegrast in Treatment of Dry Eye Disease-A Practical, Narrative Expert Review.

Dry eye disease (DED) is a multifactorial disorder affecting millions worldwide. Inflammation plays a central role in DED. The aim of this review is to critically evaluate the literature concerning the efficacy and safety of lifitegrast, a small molecule immunomodulator that blocks the action of lymphocyte function-associated antigen-1.

Temporal trajectories of long-COVID symptoms in adults with 22 months follow-up in a prospective cohort study in Norway.

Objectives: There is a lack of large studies on long-COVID symptoms with symptoms measurements before the onset of COVID-19. Therefore, long-COVID is still poorly defined.

Methods: The Norwegian COVID-19 Cohort Study is a population-based, open cohort of adult participants (aged 18-96 years) from Norway.

Executive deficits after SARS-CoV-2 infection: A cross-sectional population study.

Importance: Despite the major implications of executive deficits in day-to-day functioning, few studies have investigated this in post-acute sequelae of SARS-CoV-2 infection using standardized measures that differentiate between aspects of executive function.

Objective: Examine whether SARS-CoV-2 infection is associated with deficits in executive functions and if so, investigate the duration of this association.

Design Setting And Participants: The present research has a cross-sectional design and uses data from the Norwegian Covid-19 Cohort study.

Epigenetic aging of human blood cells is influenced by the age of the host body.

Allogenic hematopoietic stem cell transplantation is a therapeutic procedure performed over a wide range of donor and recipient age combinations, representing natural experiments of how the age of the recipient affects aging in transplanted donor cells in vivo. We measured DNA methylation and epigenetic aging in donors and recipients and found that biological epigenetic clocks are accelerated in cells transplanted into an older body and decelerated in a younger body. This is the first evidence that the age of the circulating environment influences human epigenetic aging in vivo.

Cri du chat syndrome patients have DNA methylation changes in genes linked to symptoms of the disease.

Background: Cri du chat (also called 5p deletion, or monosomy 5p) syndrome is a genetic disease caused by deletions of various lengths in the short (p) arm of chromosome 5. Genetic analysis and phenotyping have been used to suggest dose-sensitive genes in this region that may cause symptoms when a gene copy is lost, but the heterogeneity of symptoms for patients with similar deletions complicates the picture. The epigenetics of the syndrome has only recently been looked at with DNA methylation measurements of blood from a single patient, suggesting epigenetic changes in these patients.
