Article Abstract
Objective: To analyze the interobserver and intraobserver reproducibility of the visualization and continuity of the juncional zone (JZ) by three-dimensional (3D) ultrasound in infertile women, and to evaluate the sociodemographic, hormonal, and structural factors that influence these assessments.
Methods: A prospective study conducted at the Assisted Reproductive Technology Unit of Hospital Senhora da Oliveira, in the city of Guimarães, Portugal. Transvaginal 3D ultrasonography was performed, and 2 volumes were generated per case. Two observers who were blinded to each other's work analyzed these volumes, choosing the best coronal section. Four months later, one of the observers performed the same methodology. The JZ visualization was classified as optimal, satisfactory, and unsatisfactory, and the JZ continuity, as continuous and discontinuous. The interobserver and intraobserver agreements were analyzed. The influence of hormonal, structural, and sociodemographic factors on the JZ was evaluated.
Results: In total, 65 women were included in the present study. The interobserver reproducibility was substantial for JZ visualization and continuity (k = 0.635 and 0.753 respectively), and the intraobserver reproducibility was very good for JZ visualization and continuity (k = 0.884 and 0.816 respectively). Trilaminar endometrial pattern was associated with optimal JZ visualization ( = 0.012). The increase of 1 unit in the level of serum estradiol represents a 9.9% decrease in the odds of unsatisfactory visualization of the JZ (odds ratio [OR] = 0.9; 95% confidence interval [95%CI] = 0.814-0.996; = 0.042). Endometriosis increases the odds of unsatisfactory visualization by 24 times (OR = 23.7; 95%CI = 1.262-437.057; = 0.034). The prevalence of discontinuous JZs was of 60%. Myomas and endometriosis were associated with discontinuous JZs ( = 0.034 and 0.016 respectively).
Conclusion: The assessment of JZ visualization and continuity by 3D ultrasound is reproducible enough to be used in the clinical practice.

SIRT1 as a potential target for age-related eye diseases: mechanisms and therapeutic strategies.

Age-related eye diseases (AREDs) are the leading cause of visual impairment in the elderly, affecting the structure of the anterior and posterior segments of the eye, significantly reducing the quality of life of patients, and even leading to irreversible blindness. Typical AREDs include age-related cataract (ARC), dry eye disease (DED), age-related macular degeneration (AMD), glaucoma, and diabetic retinopathy (DR), the global prevalence of which continues to rise, becoming a serious public health concern. SIRT1 is an NAD + dependent deacetylase, which plays an important physiological regulatory role in ocular tissues, mainly affecting gene expression and various cellular processes by regulating the acetylation status of substrate proteins.

Objective: To compare the efficacy of different settings in continuous-wave transscleral cyclophotocoagulation (CW-TSCPC).
Design: Prospective, randomized, triple-blind clinical trial in a single tertiary center.
Participants: Adult glaucoma patients who need continuous wave-transscleral cyclophotocoagulation to control intraocular pressure (IOP) or prevent or treat ocular pain/discomfort secondary to increased IOP.

Purpose: To analyze macular microvascular networks and investigate correlations between visual acuity and quantitative parameters in patients with Leber's hereditary optic neuropathy (LHON) using optical coherence tomography angiography (OCTA).
Methods: An observational, cross-sectional study was conducted, including 25 eyes from 25 genetically confirmed chronic LHON patients and 25 eyes from 25 age-matched healthy controls. Images were obtained using a spectral domain OCTA system.

Purpose: To review the literature and identify the health-related quality-of-life (HRQL) outcomes that used a validated instrument in the assessment of upper blepharoplasty, blepharoptosis surgery, or combination surgery.
Methods: A literature search was last conducted in the PubMed database in January 2025 to identify all studies in the English language investigating HRQL outcomes that used a validated instrument in the assessment of upper blepharoplasty, blepharoptosis surgery, or combination surgery. The literature search yielded 773 citations, and 20 studies met the inclusion criteria.
Quantitative Doppler Shape Analysis in Functional Tricuspid Regurgitation.

Background: The shape of the continuous wave Doppler (CWD) envelope in functional tricuspid valve regurgitation (fTR) results from the dynamic interplay between flow, pressure gradient and impedance. Although the v-wave cut-off shape in fTR is a well-recognized feature of severe TR, the complete spectrum of TR CWD shapes across the different fTR severity ranges has not been thoroughly explored, which is the scope of the present study.
Methods: In 245 patients with fTR, TR was graded with transthoracic echocardiography using the corrected proximal isovelocity surface area method and CWD shapes were scored, both qualitatively (using visual scoring into parabolic, triangular or v-wave cut-off categories) and quantitatively using a novel Vmax/Vmean parameter and time-to-peak velocity corrected for TR duration (TTP/TRD).
