Purpose: We evaluated the late-onset ocular hypotensive effect of ripasudil after long-term administration in real-world clinical data and investigated its associated factors in primary open-angle glaucoma (POAG).

Patients And Methods: We reviewed the clinical patients with POAG who newly started ripasudil without changes of treatment. Enrolled eyes were assigned to two groups: positive group with the late-onset effect and negative group.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is common in patients with obesity and diabetes and can lead to serious complications. This study aimed to evaluate fundus photographs using artificial intelligence to explore the relationships between diabetic retinopathy (DR), MASLD, and related factors. In this cross-sectional study, we included 1,736 patients with a history of diabetes treatment or glycated hemoglobin (HbA1c) levels of ≥6.

After developing job-exposure matrices (JEMs) for screen and sedentary time, we aimed to assess the associations between the JEM-derived exposures and various ocular diseases. We collected data from patients hospitalized from 2005 to 2021. JEMs were developed from 41,718 patients with occupational information and screen and sedentary times.

Article Synopsis
  • A job-exposure matrix was created to analyze sedentary behavior in relation to non-communicable diseases, using data from over 41,000 individuals.
  • The matrix was applied to a large cohort in a case-control study, revealing a connection between higher sedentary time and increased risks of diabetes, heart attacks, and endometrial cancer, while suggesting lower stroke risks.
  • The findings emphasize the need to address sedentary behavior in workplace settings due to its significant health implications.

Herein, we examined body mass index (BMI) in OPDS to determine SES-associated anthropometric characteristics.

Design: Retrospective cohort study.

Article Synopsis
  • The study compared the glaucoma detection accuracy of a new head-mounted binocular visual perimeter screening program (ISP) with that of frequency doubling technology (FDT).
  • It involved 168 eyes (including non-glaucoma and glaucomatous eyes) and found that ISP performed comparably or better than FDT in detecting different stages of glaucoma, with specific AUC values reported.
  • Additionally, ISP required significantly less testing time than FDT, suggesting it could be an effective and efficient tool for glaucoma screening in larger populations.

Purpose: To assess the effects of intraocular lens (IOL) decentration and tilt, as well as age, on postoperative visual function (corrected distance visual acuity [CDVA] and contrast sensitivity) by comparing an extended depth-of-focus IOL using higher order aspheric optics against a monofocal IOL from the same platform.

Methods: This retrospective observational study targeted patients without other eye diseases who underwent surgery to implant the Tecnis Eyhance OptiBlue or the monofocal IOL Tecnis OptiBlue 1-Piece (J&J Vision) during cataract surgery from November 2021 to December 2022. The effects of age, axial length, IOL decentration, tilt, and corneal higher order aberrations (HOAs) on the postoperative 5 m CDVA and area under log contrast sensitivity function (AULCSF) under photopic and scotopic conditions were evaluated within 3 months of surgery.

Purpose: To examine the variability in glaucoma screening using fundus images among physicians, including non-ophthalmologists.

Patients And Methods: Sixty-nine eyes from 69 patients, including 25 eyes with glaucoma, were included from the Jikei University Hospital from July 2019 to December 2022. Fundus images were captured using TRC-NW8 (Topcon Corporation, Tokyo, Japan), and were interpreted by 10 non-ophthalmologists, 10 non-specialist ophthalmologists, and 9 specialists for diagnostic accuracy.

Article Synopsis
  • A small percentage (1%) of certain tyrosine kinase fusions have been identified in soft tissue sarcomas through DNA sequencing, but these fusions are not common among the 80% of fusion-negative sarcomas, which remain genetically unexplored.
  • The study aims to investigate whether DNA/RNA analysis can reveal genetic changes and identify potential tyrosine kinase fusions in tumor-specific, fusion-negative sarcomas, particularly focusing on their response to drug treatment in vitro.
  • Research was conducted on 100 patients with bone and soft tissue sarcomas between 2017 and 2020, with 90 patients being found eligible for the study despite some exclusions due to follow-up

This cross-sectional study aimed to investigate the promoting and inhibitory factors of diabetic retinopathy (DR) according to diabetes mellitus (DM) stage using standardized evaluation of fundus images by artificial intelligence (AI). A total of 30,167 participants underwent blood and fundus examinations at a health screening facility in Japan (2015-2016). Fundus photographs were screened by the AI software, RetCAD and DR scores (DRSs) were quantified.

This study proposed a numerical method of dynamic mode decomposition with memory (DMDm) to analyze multidimensional time-series data with memory effects. The memory effect is a widely observed phenomenon in physics and engineering and is considered to be the result of interactions between the system and environment. Dynamic mode decomposition (DMD) is a linear operation-based, data-driven method for multidimensional time-series data proposed in 2008.

Aims: A distinct subset of lung adenocarcinomas (LADs), arising from a series of peripheral lung cells defined as the terminal respiratory unit (TRU), is characterised by thyroid transcription factor 1 (TTF-1) expression. The clinical relevance of transcription factors (TFs) other than TTF-1 remains unknown in LAD and was explored in the present study.

Methods And Results: Seventy-one LAD samples were subjected to high-throughput transcriptome screening of LAD using cap analysis gene expression (CAGE) sequencing data; CAGE provides genome-wide expression levels of the transcription start sites (TSSs).

Comprehensive analyses using clinical sequences subcategorized osteosarcoma (OS) into several groups according to the activated signaling pathways. Mutually exclusive co-occurrences of gene amplification ( and ) have been identified in approximately 40% of OS, representing candidate subsets for clinical evaluation of additional therapeutic options. Thus, it would be desirable to evaluate the specific gene amplification before starting therapy in patients with OS.

Aims: The acetabular morphology varies greatly among individuals, and hypoplasia is more common in Asia than in Europe. Dislocation after bipolar hip arthroplasty (BHA) for femoral neck fracture occurs at a constant rate, and is affected by the acetabular morphology. This study aimed to clarify individual differences in the acetabula of Asian patients with displaced femoral neck fractures.

Background/objectives: To assess the influence of patient age on visual outcomes in eyes with diffractive multifocal intraocular lenses (IOLs) SUBJECTS/METHODS: Based on age, we classified eyes with diffractive multifocal IOL into four groups: u50 (under 50 years old), 50s (50-59 years), 60s, and 70s. Corrected distance (CD), distance-corrected near (DCN) visual acuity (VA), and defocus curve were measured postoperatively. Using an "area-of-focus" metric, the distant, intermediate, and near area-of-focus (AoF) were also measured.

There are multiple transcription start sites (TSSs) in agreement with multiple transcript variants encoding different isoforms of NKX2-1/TTF-1 (thyroid transcription factor 1); however, the clinicopathological significance of each transcript isoform of NKX2-1/TTF-1 in lung adenocarcinoma (LAD) is unknown. Herein, TSS-level expression of NKX2-1/TTF-1 isoforms was evaluated in 71 LADs using bioinformatic analysis of cap analysis of gene expression (CAGE)-sequencing data, which provides genome-wide expression levels of the 5'-untranslated regions and the TSSs of different isoforms. Results of CAGE were further validated in 664 LADs using in situ hybridisation.
