Objectives: Our aim for this study was to evaluate dialysis nurses' ability to detect and recover from nursing errors.
Methods: Two clinical cases with a total of 12 embedded errors were constructed. The errors were based on real events but were modified for the experimental design by an expert dialysis nurse. A total of 31 registered nurse subjects "talked aloud" as they read through the 2 cases and answered a set of predesigned knowledge-based and procedural questions. The talk-aloud sessions were recorded and transcribed for analysis of errors detected and recovered.
Results: Performance on procedurally based error detection and recovery was significantly higher as a function of expertise (P < 0.05), where more-experienced nurses performed better than the less-experienced nurses in detecting and recovering procedurally based errors. However, no differences were found for knowledge-based errors.
Conclusions: Expert nurses develop a special ability to detect and recover from nursing errors, but the nature of these errors depends on the nature of the task. Dialysis nursing requires more knowledge of procedures rather than conceptual knowledge in their routine work, and thus, the nurses develop better procedurally based skills. This raises concern about nurses making knowledge-based or conceptual errors, which, if made, are not detected or corrected. The need for understanding conceptual knowledge underlying procedures and for training in error detection and correction strategies is discussed in the context of nursing.

Chemotherapy resistance (CR) represents one of the most important barriers to effective oncological therapy and often leads to ineffective intervention and unfavorable clinical prognosis. Emerging studies have emphasized the vital significance of extracellular RNA (exRNA) in influencing CR. This thorough assessment intends to explore the multifaceted contributions of exRNA, such as exosomal RNA, microRNAs, long non-coding RNAs, and circular RNAs, to CR in cancer.

Background Detection and segmentation of lung tumors on CT scans are critical for monitoring cancer progression, evaluating treatment responses, and planning radiation therapy; however, manual delineation is labor-intensive and subject to physician variability. Purpose To develop and evaluate an ensemble deep learning model for automating identification and segmentation of lung tumors on CT scans. Materials and Methods A retrospective study was conducted between July 2019 and November 2024 using a large dataset of CT simulation scans and clinical lung tumor segmentations from radiotherapy plans.

Real-time moving target trajectory prediction is highly valuable in applications such as automatic driving, target tracking, and motion prediction. This paper examines the projection of three-dimensional random motion of an object in space onto a sensing plane as an illustrative example. Historical running trajectory data are used to train a reserve network.

Given close relationships between ocular structure and ophthalmic disease, ocular biometry measurements (including axial length, lens thickness, anterior chamber depth, and keratometry values) may be leveraged as features in the prediction of eye diseases. However, ocular biometry measurements are often stored as PDFs rather than as structured data in electronic health records. Thus, time-consuming and laborious manual data entry is required for using biometry data as a disease predictor.
