Overcrowding in emergency departments (EDs) is a global challenge, leading to prolonged waiting times and adverse patient outcomes. Telemedicine has emerged as a promising solution, enabling remote consultation, triage, and real-time specialist input. Despite its growing application, limited systematic research exists on its specific role in ED triage and care.

Article Synopsis
  • Children's eye disorders can lead to serious vision loss, and there's a need for faster diagnosis; this study looks into parents' awareness and practices regarding eye health screenings for preschoolers in Jazan, KSA.
  • A survey of 522 parents revealed that only 38.4% had high knowledge about eye care, with education playing a key role, while over 90% believed in the importance of early eye exams.
  • Despite the positive attitude towards screening, many parents (47.0%) took their children for eye examinations between ages 1-5, indicating room for improvement in early eye care practices.

Terbium and nitrogen co-doped carbon dots (Tb@N-CDs), combined with α-lipoic acid-functionalized copper nanoclusters (LA@CuNCs), were proposed for the ratiometric detection of quinolone (QA) antibiotics. In this system, Tb@N-CDs facilitate the aggregation of LA@CuNCs, enhancing its fluorescence emission at 670 nm via aggregation-induced emission enhancement (AIEE). Meanwhile, the fluorescence emission of Tb@N-CDs at 460 nm diminishes due to Förster resonance energy transfer (FRET).

This paper reports the green synthesis and characterization of nickel-integrated chitosan-modified cerium oxide (CHS-CeO@Ni) nanocatalyst aimed at the efficient hydrogenation of 4-nitrophenol (4-NP) and the reduction of azo dyes such as methyl orange (MO) and Congo red (CR). The CHS-CeO@Ni nanocatalyst was synthesized via a green method, where Arnebia benthamii plant extract was used as a reducing agent to deposit nickel nanoparticles onto the CHS-CeO nanocomposite. Results confirmed the successful integration of Ni into the CHS-CeO matrix, resulting in a highly crystalline, mesoporous structure with a substantial surface area of 78.

Melamine, often used as an adulterant in infants' formula due to its high protein content, can be harmful when ingested in large amounts, leading to the formation of cyanurate-melamine co-crystals in infants and potentially causing kidney damage. In this study, we introduce a fluorescent method for the selective and reliable detection of melamine in milk and infants' formula. The fluorescent probe comprises copper nanoclusters (Cu NCs) functionalized with thiosalicylic acid (TSA) and polyvinylpyrrolidone (PVP) as double-protecting ligands.
