Aims: To investigate the association of cumulative childhood adversity with frailty and whether this association differs across socioeconomic status.

Methods: The study included 6100 middle-aged and older adults in China from the CHARLS-2014 life course survey and the CHARLS-2015 survey. A frailty index (FI) was constructed from 39 questionnaire items, with higher values indicating higher frailty.

In recent decades, the impact of air pollution on eye health has been emphasized, but the effect of air pollution on changes in refractive error is still unknown. A comprehensive retrospective cohort study was conducted to address this, utilizing the China Medical University Hospital Clinical Research Data Repository (CMUH-CRDR). It included 4,399 participants aged 6-12 years, with 2,166 females and 2,223 males, who visited the ophthalmology department between 2003 and 2019, ensuring a robust and representative sample.

Solute carrier 25 member 21 () serves as an oxodicarboxylate carrier, which mainly conveys 2-oxoadipate from the cytoplasm to the mitochondria a reverse exchange mechanism. Previous studies have indicated that the capacity for glucose consumption is significantly enhanced in 3T3-L1 cells overexpressing . In this study, we upregulate in 3T3-L1 cells to further probe into the downstream key metabolic genes of .

Article Synopsis
  • The study investigated the potential link between tinnitus (ringing in the ears) and uveitis (inflammation of the eye) due to shared autoimmune pathways.
  • It analyzed data from over 31,000 tinnitus patients compared to more than 124,000 individuals without tinnitus, from 2001 to 2018.
  • Results indicated that tinnitus patients have a significantly higher risk of developing uveitis, suggesting a possible association between the two conditions.

Article Synopsis
  • - The study aimed to identify OCT-based biomarkers that can help predict treatment response in diabetic macular edema (DME) patients receiving intravitreal ranibizumab injections, which is crucial for customizing treatment plans.
  • - Researchers analyzed data from 65 eyes of 35 patients, tracking visual acuity, central retinal thickness, and other OCT features at various time points before and after treatment.
  • - Results showed that specific biomarkers like DRIL, LONLC, and SRF were significant predictors of visual and structural improvements, demonstrating the potential value of OCT biomarkers in managing DME.

: To report the initial response to a single intravitreal brolucizumab (IVI-B) injection in wet age-related macular degeneration (wAMD) or polypoidal choroidopathy (PCV) complicated with either persistent subretinal fluid (SRF) or pigment epithelial detachment refractory to previous anti-vascular endothelial growth factor (anti-VEGF) therapy. : In this retrospective study, all eyes received a single IVI-B (6 mg/0.05 mL) for wAMD or PCV with treatment-resistant SRF or PED.

Purpose: Shear wave elastography (SWE) accurately and sensitively evaluates arterial wall stiffness by quantifying the elastic modulus (EM); however, the absence of reference values has precluded its widespread clinical application. This prospective cohort study aimed to establish reference values for the carotid EM using SWE; investigate the main determinants of the EM; and evaluate EM changes in coronary slow flow (CSF), which is characterized by delayed coronary opacification without evident obstructive lesion in epicardial coronary artery on angiography.

Method: This study enrolled 169 healthy volunteers and 30 patients with CSF.

Purpose: To review the clinical features, diagnosis, and treatment of idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) and to report a case with the use of ultra-widefield fluorescein angiography (UWFA) for confirming the precise staging of IRVAN and aid in early treatment. The patient improved after being treated with intravitreal aflibercept injection.

Results: A 26-year-old female complained of progressive blurred vision OD for one week.

Purpose: To identify optical coherence tomography (OCT) biomarkers that may predict functional and anatomical outcomes in diabetic macular edema (DME) patients treated with intravitreal dexamethasone (DEX) implant.

Materials And Methods: Sixty-four eyes from 50 patients with DME were enrolled. Best-corrected visual acuity (BCVA) and OCT biomarkers including central retinal thickness (CRT), subretinal fluid (SRF), intraretinal cysts (IRC), ellipsoid zone disruption (EZD), disorganization of retinal inner layers (DRIL), hard exudate (HE), hyperreflective foci (HRF), epiretinal membrane (ERM), and vitreomacular interface (VMI) changes were evaluated at baseline and at 3, 6, and 12 months after treatment.

Background: Ultrafast ultrasound imaging has been demonstrated to be an effective method to evaluate carotid stiffness through carotid pulse-wave velocity (PWV) with high reproducibility, but a lack of reference values has precluded its widespread use in clinical practice. The aims of this study were to establish reference values of PWV for ultrafast ultrasound imaging in a prospective, multicenter, population-based cohort study and to investigate the main determinants of carotid PWV.

Methods: A total of 1,544 healthy Han Chinese volunteers (581 men [38%]; age range, 18-95 years) were enrolled from 32 collaborating laboratories in China.

Background: Accurate assessment of left ventricular (LV) systolic function is important after coronary artery bypass grafting (CABG). LV ejection fraction (LVEF) is conventionally used to evaluate LV systolic function; deformation parameters can be used to detect subtle LV systolic dysfunction. It is unclear whether an incised pericardium without sutures during CABG could affect LV morphology and function.
