Deep learning model for diagnosis of venous thrombosis from lower extremity peripheral ultrasound imaging.

Deep vein thrombosis (DVT) causes significant healthcare burdens worldwide. This study aims to establish a deep learning model for the diagnosis of DVT from the assessment of vein compressibility. Considering the complexity of ultrasound images, convolutional neural networks with UNet and residual neural network (ResNet) are established for image segmentation, from venous duplex ultrasonographic video images, obtained through standard and portable handheld ultrasound methods.

Incidence and Progression of Diabetic Retinopathy After Cataract Surgery: A Systematic Review and Meta-Analysis.

Purpose: The impact of cataract surgery on diabetic retinopathy (DR) in patients with diabetes mellitus (DM) remains uncertain. This study aimed to investigate the incidence and progression of DR in patients with DM who underwent cataract surgery.

Design: Meta-analysis.

Photoelectric Properties of GaSSe (0 ≤ ≤ 1) Layered Crystals.

In this study, the photoelectric properties of a complete series of GaSSe (0 ≤ ≤ 1) layered crystals are investigated. The photoconductivity spectra indicate a decreasing bandgap of GaSSe as the Se composition increases. Time-resolved photocurrent measurements reveal a significant improvement in the response of GaSSe to light with increasing .

Efficacy and Safety of Low-Dose Atropine on Myopia Prevention in Premyopic Children: Systematic Review and Meta-Analysis.

Early-onset myopia increases the risk of irreversible high myopia. This study systematically evaluated the efficacy and safety of low-dose atropine for myopia control in children with premyopia through meta-analysis using random-effects models. Effect sizes were calculated using risk ratios (RRs) with 95% confidence intervals (CIs).
