Article Synopsis
  • - The study investigates the link between HLA genotypes and the severity of COVID-19 in 209 Japanese patients, identifying how specific alleles correlate with severe respiratory cases over different epidemic periods (pre-Omicron and Omicron).
  • - Significant associations were found, particularly with alleles HLA-DQA1*01:03 and HLA-DQB1*06:01, showing higher frequencies in severe COVID-19 cases compared to non-severe cases, primarily during the pre-Omicron period.
  • - There was a strong correlation between the two significant alleles (r = 0.91), indicating they are often inherited together, and their presence in the severe group highlights potential genetic factors influencing COVID-19

Introduction: Dry eye can compromise corneal astigmatism measurement repeatability during preoperative cataract surgery examination. No previous studies have analyzed the effectiveness of long-acting 3% diquafosol sodium (LA-DQS) on astigmatism measurement repeatability. This research assessed the effect of LA-DQS on astigmatism measurement repeatability in preoperative patients with cataract and short tear break-up time (TBUT) type dry eyes in both eyes of the same patient.

Background: Intestinal involvement in Behçet's disease (BD) is associated with poor prognosis and is more prevalent in East Asian than in Mediterranean populations. Identifying the genetic causes of intestinal BD is important for understanding the pathogenesis and for appropriate treatment of BD patients.

Methods: We performed genome-wide association studies (GWAS) and imputation/replication genotyping of human leukocyte antigen (HLA) alleles for 1,689 Korean and Turkish patients with BD (including 379 patients with intestinal BD) and 2,327 healthy controls, followed by replication using 593 Japanese patients with BD (101 patients with intestinal BD) and 737 healthy controls.

Corneal astigmatism is reportedly associated with polymorphisms of the platelet-derived growth factor receptor alpha (PDGFRA) gene region in Asian populations of Chinese, Malay, and Indian ancestry and populations of European ancestry. In this study, we investigated whether these PDGFRA polymorphisms are associated with corneal astigmatism in a Japanese population. We recruited 1,535 cases with corneal astigmatism (mean corneal cylinder power across both eyes: ≤  - 0.

Immune checkpoint inhibitors (ICIs) activate anti-tumor activity by inhibiting immune checkpoint molecules that suppress inflammatory T-cell activity. However, ICIs can initiate excessive immune responses, thereby causing immune-related adverse events (irAEs). ICI-associated uveitis (ICIU) is an irAE that affects the eyes.

Introduction: Although uncommon, incomplete capsulotomy, anterior capsule tags and anterior capsule tears are still encountered during femtosecond laser-assisted cataract surgery (FLACS), resulting in surgical complications. This highlights the need to improve femtosecond laser-assisted capsulotomy technique to reduce capsulotomy-related complications. Therefore, the purpose of this study was to investigate the efficacy of a newly developed, modified technique of setting capsulotomy irradiation thickness in lowering the incidence of capsulotomy-related complications in FLACS.

Article Synopsis
  • The study aimed to explore the relationship between certain genetic variations (polymorphisms) and Behçet's disease (BD) in a Japanese population.
  • Researchers recruited 734 patients with BD and 1789 healthy controls to analyze two specific genetic markers, finding that one (rs9577873) had no significant correlation with BD, while the other (rs4857037) showed an increased risk linked to the A allele.
  • The results suggest that higher expression levels related to the A allele of rs4857037 may influence tyrosine kinase receptor signaling, potentially contributing to the development of BD.

Introduction: The authors evaluated student achievement of interprofessional education (IPE) core competencies during two formats (one hybrid and one completely online) of an IPE simulation designed for pharmacy and nursing students.

Methods: This IPE simulation was designed to teach students to use distance technologies to collaborate on patient care. In 2019, pharmacy (n = 83) and nursing (n = 38) students attended the hybrid (in-person and online) IPE simulation (SIM 2019) with the use of a telepresence robot.

Background: Differences between programmed capsulorhexis diameter and actual resulting capsulorhexis diameter (ARCD) are commonly encountered in femtosecond laser-assisted cataract surgery (FLACS). The purpose of this study was to identify the preoperative ophthalmic variables influencing capsulorhexis diameter index (CDI) in FLACS for adults and create a multiple linear regression model for obtaining a more accurate capsulorhexis diameter.

Methods: This retrospective study involved sixty-seven eyes of 44 patients who received FLACS and intraocular lens implantation.

  • The study focused on arthralgia, a common side effect of immune checkpoint inhibitors (ICIs) in cancer treatment, and its impact on overall survival (OS) in patients.
  • Researchers conducted a meta-analysis involving 14,377 patients from 24 randomized controlled trials (RCTs), finding that those with ICI-induced arthralgia generally experienced better OS.
  • The analysis also highlighted a significant association between the development of arthralgia and other immune-related adverse events, suggesting the need for careful monitoring of patients experiencing these side effects.

Introduction: The present study aimed to compare the effects of rebamipide and artificial tears during the perioperative period of cataract surgery on the postoperative visual outcomes.

Methods: Seventy-two eyes from 36 patients with a cataract were enrolled. Rebamipide (group R) was administered in one eye and Mytear® artificial tear ophthalmic solution (group A) in the other eye from 4 weeks preoperatively to 3 months postoperatively.

Refractive changes are reportedly affected by age, sex, and current refractive error. To clarify the pattern of refractive changes in a Japanese population, we conducted a 5-year follow-up longitudinal analysis of spherical equivalent (SE) refractive changes with stratification by sex, age, and SE in 593,273 eyes from Japanese individuals ages 3-91 years. The 5-year SE change with myopic shift dramatically increased over time after age 4 years, and the largest change was observed in both males and females who were age 8 years at baseline [males: - 2.

Background: IgG4-related disease (IgG4-RD) is an immune-mediated disorder characterized by high serum IgG4 concentration and IgG4-bearing plasma cell infiltration in affected organs. IgG4-related periaortitis/periarteritis is a recently identified disease entity in IgG4-RD that affects the cardiovascular system. Since the genetic factors related to disease onset are unclear, we examined the genetic associations with IgG4-related periaortitis/periarteritis susceptibility.

Introduction: Refractive accuracy is crucial for increasing patient satisfaction after cataract surgery. Tear film instability caused by dry eye can lead to inaccurate measurement of corneal power, which is one of the most important factors for postoperative refractive calculation. This study investigated the effect of 2% rebamipide ophthalmic suspension on the predicted refractive accuracy for cataract surgery in patients with dry eye.

Purpose: Halos are a chief source of patient dissatisfaction after multifocal intraocular lens (IOL) implantation. The primary purpose of this study was to investigate the influence of age, postoperative refraction, and pre- and postoperative pupil size on postoperative halo size with a trifocal diffractive IOL (AcrySof IQ PanOptix) and extended depth-of-focus (EDOF) IOL (TECNIS Symfony) to determine whether these factors could predict postoperative halo size.

Patients And Methods: This single-center, open-label study conducted between October 2018 and April 2020 in Yokosuka, Japan included 160 patients: 80 with PanOptix and 80 with Symfony IOLs.

Background: Evidence suggests that denture non-use is significantly associated with activities of daily living, oral function, and cognitive decline. Few studies have focused on the possibility that the indications for denture use may differ depending on the cognitive and physical functions in older adults requiring long-term care.

Objectives: The aim of this study was to elucidate the factors associated with denture non-use in older adults requiring long-term care.
