Efficacy of observational learning on nursing students' learning outcomes in delirium care simulation: A parallel-group randomized trial.

Background: While the learning outcomes of observational learning in simulation-based experiences have been documented, there is a paucity of studies that have provided evidence of the efficacy of observational learning in influencing reaction, performance, and behavioral changes.

Purpose: This study aimed to assess the efficacy of structured observational learning on the learning outcomes of nursing students in delirium care simulations.

Methods: A parallel-group randomized trial design was employed.

Extensor Pollicis Longus Tendon Rupture With Concomitant Electrodiagnostic and MRI Findings of Posterior Interosseous Nerve Palsy: A Report of 2 Cases and Review of the Literature.

Cases: Two patients with spontaneous loss of thumb interphalangeal joint extension were referred after history, electrodiagnostic, and/or magnetic resonance imaging (MRI) findings were felt to demonstrate a posterior interosseous nerve (PIN) palsy. Subsequent physical examination and additional directed studies suggested an alternative explanation: rupture of the extensor pollicis longus (EPL) tendon, subsequently confirmed at surgery. An extensor indicis proprius to EPL transfer restored thumb function.

Current Concepts of the Management of Painful Traumatic Peripheral Nerve Neuromas.

Painful neuromas are a complex clinical condition that results in notable disability and functional impairment after injury to a peripheral nerve. When regenerating axons lack a distal target, they form a stump neuroma. Up to 60% of neuromas are painful because of mechanical sensitivity and crosstalk between nerve fibers.

LIN28B-mediated PI3K/AKT pathway activation promotes metastasis in colorectal cancer models.

Colorectal cancer (CRC) remains a leading cause of cancer death due to metastatic spread. LIN28B is overexpressed in 30% of CRCs and promotes metastasis, yet its mechanisms remain unclear. In this study, we genetically modified CRC cell lines to overexpress LIN28B, resulting in enhanced PI3K/AKT pathway activation and liver metastasis in mice.

Pre-Melting-Assisted Impurity Control of β-GaO Single Crystals in Edge-Defined Film-Fed Growth.

This study reveals the significant role of the pre-melting process in growing high-quality (100) β-GaO single crystals from 4N powder (99.995% purity) using the edge-defined film-fed growth (EFG) method. Among various bulk melt growth methods, the EFG method boasts a fast growth rate and the capability of growing multiple crystals simultaneously, thus offering high productivity.
