To investigate the hemispheric lateralization of attentional processes during visual search tasks depending on the stimulus material embedding the target, twelve patients with unilateral left (n = 7) or right (n = 5) parietal lesions and 20 age and education matched healthy controls (HC) were recruited. We used a visual search task for a uniquely tilted oblique bar embedded in an object shape 'N' or in its mirror reversal 'И'. The accuracy and the averaged reaction times (RTs) in each stimulus type ('N' or 'И') were analysed. HC presented significantly longer RTs when the target bar was embedded in 'N' among its mirror reversed 'И' (p < .05). This "reversed letter effect" was also found in the right parietal patients (p < .001), while no evidence of a reversed letter effect was found in the left parietal patients.

Background: Perception-related errors comprise most diagnostic mistakes in radiology. To mitigate this problem, radiologists use personalized and high-dimensional visual search strategies, otherwise known as search patterns. Qualitative descriptions of these search patterns, which involve the physician verbalizing or annotating the order he or she analyzes the image, can be unreliable due to discrepancies in what is reported versus the actual visual patterns.

Precis: Glaucoma surgery impacts corneal graft survival differently by procedure type, with GDDs being most effective at reducing intraocular pressure. However, graft survival rates are comparable across trabeculectomy, CPC, and GDDs. Trabeculectomy improves visual acuity best but often requires additional interventions.

This study examined the effects of different fatigue types on action anticipation and physical performance in high-level volleyball players. Twenty-four participants underwent four counterbalanced conditions: 60-min cycling at 60% peak power output, 60-min Stroop task, 60-min cycling at 60% peak power output with Stroop task and 60-min neutral documentary to induce physical fatigue (PF), mental fatigue (MF), dual fatigue (DF) and control group (CG), respectively. Action anticipation (anticipation test and visual search test) and physical performance (countermovement jump, T-test, and spike test) were conducted at baseline, immediately after (Post1), and after 10-min rest (Post2).

Purpose: The aim of this study was to evaluate the efficacy and safety of the Ahmed glaucoma valve in pediatric patients with refractory glaucoma.
Methods: A comprehensive literature search was conducted across multiple major databases, including PubMed, Embase, the Cochrane Library of Systematic Reviews, Science Direct, China's National Knowledge Infrastructure, and the Wanfang database. We retrieved studies published before December 2022 that met the inclusion criteria, including clinical controlled trials (randomized controlled trials) and clinical noncontrolled trials (non-randomized controlled trials) on the use of Ahmed glaucoma valve in pediatric patients with refractory glaucoma.

Objective: To use bibliometric methods to analyze the prospects and development trends of artificial intelligence(AI) in oncology nursing from 1994 to 2024, providing guidance and reference for oncology nursing professionals and researchers.
Methods: The core set of the Web of Science database was searched for articles from 1994 to 2024. The R package "Bibliometrix" was used to analyze the main bibliometric features, creating a three-domain chart to display relationships among institutions, countries, and keywords.
