Article Synopsis
  • The study focused on R544C variant carriers in Taiwan who have CADASIL, investigating if white matter hyperintensities (WMHs) appear before symptoms and how these WMHs relate to cognitive function.
  • It included 63 asymptomatic R544C carriers and 37 controls, revealing that the carriers had significantly higher WMH volumes and cognitive scores were lower, especially after age 48.
  • Factors linked to increased WMH volumes were identified as age, hypercholesterolemia, and a vascular risk factor index, with a notable association between WMHs and cognitive performance.

Cardiovascular fitness (CRF) has been consistently linked to cognitive performance and academic achievement, and inhibitory control has been recognized as a key predictor of academic success. However, few studies have explored whether inhibitory control mediates the relationship between CRF and academic performance in children, and the existing findings are inconclusive because of certain limitations. This study investigated the mediating role of inhibitory control in the association between CRF and academic achievement among preadolescents while also addressing the related limitations.

Purpose: To evaluate the serum lipid levels, including total cholesterol, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) of patients with normal tension glaucoma (NTG) and to investigate the relationship between serum HDL levels and the severity of NTG.

Methods: In this cross-sectional, case-control study, 282 NTG subjects and 202 control subjects were enrolled from the outpatient clinic of the Department of Ophthalmology at Taichung Veterans General Hospital in central Taiwan from 2015 to 2021. Fasting cholesterol, HDL, and LDL levels were evaluated using a biochemical analyzer (ARCHITECT c16000).

Exosomes are membranous structures measuring between 40-120 nm that are secreted by various cells of the human body into the body fluid system. Exosomes contain proteins, mRNA, miRNA, and signaling molecules, and physiologically they assist in the intercellular transport of proteins and RNA molecules. In this study, we used an immunoaffinity filter paper platform combined with scanning electron microscopy and microfluidic systems to detect the size of exosomes within the aqueous humor.

Background: Cryptococcosis is one of the most frequent fungal eye infections in patients with immunosuppression. Currently, treatment approaches for non-meningeal, non-pulmonary cryptococcosis are based on those used for cryptococcal meningitis or pneumonia.

Case Presentation: We present a rare case of non-meningeal, non-pulmonary cryptococcosis with clinical manifestations limited to one eye of a cadaveric kidney transplant recipient with chronic-active antibody-mediated rejection.

Article Synopsis
  • The study aimed to compare the biomechanical properties of corneas in patients with osteogenesis imperfecta (OI) to those with keratoconus and normal controls, using advanced imaging technology.* -
  • Results showed that OI patients had higher biomechanical indices compared to normal controls but were less stable and easier to deform, while keratoconus patients exhibited the lowest stability and stiffness compared to both OI and normal groups.* -
  • The findings highlight that although OI corneas are less stable, their material stiffness is similar to that of normal controls, contrasting with the more severe biomechanical weaknesses found in keratoconus.*

Purpose: To characterize the corneal biomechanical properties of primary angle closure glaucoma (PACG) and to investigate the diagnostic performance of combining corneal biomechanical parameters and anterior segment parameters in detecting PACG.

Methods: This retrospective cross-sectional study evaluated 79 and 81 eyes of normal controls and patients with PACG, respectively. Corvis Biomechanical Factor (CBiF) and anterior chamber volume (ACV) were measured using the Corvis ST and Pentacam, respectively.

This study examined the effects of coordinative exercise on children's sustained attention and perceptual discrimination in a school-based physical education (SBPE) setting. Seventy-three children received an intervention of moderate-to-vigorous intensity coordinative exercise, and 75 children participated in a moderate-to-vigorous intensity physical activity as part of a regular physical education class. Two neuropsychological tests of executive function (EF) were used to assess attention and perceptual discrimination functions before and after each treatment.

Deep learning-based software is developed to assist physicians in terms of diagnosis; however, its clinical application is still under investigation. We integrated deep-learning-based software for diabetic retinopathy (DR) grading into the clinical workflow of an endocrinology department where endocrinologists grade for retinal images and evaluated the influence of its implementation. A total of 1432 images from 716 patients and 1400 images from 700 patients were collected before and after implementation, respectively.
