Nursing shortages are a significant problem that affects healthcare access, outcomes, and costs and challenges the delivery of care in hospitals. The virtual nursing delivery model enables the provision of expert nursing care from a remote location, using technology such as audio/video communication, remote monitoring devices, and access to the electronic health record. However, little is known about the structure and processes supporting the implementation of virtual nursing in healthcare systems.

- - The study aimed to evaluate how effective contrast-enhanced CT scans are in diagnosing small bowel bleeding by analyzing patient data over nearly a decade, categorizing cases into diverticulum and non-diverticulum groups based on the cause of bleeding.
- - Among 165 patients, nearly half showed active bleeding, with Crohn's disease being the most common source; significant differences were noted in diagnostic methods, with surgery mainly used for diverticulum cases and endoscopy for non-diverticulum cases.
- - The results highlighted that CT scans were particularly useful for detecting diverticular bleeding, showing higher rates of contrast material leakage in these patients compared to others.
Objectives: This study investigated the use of radiomics for diagnosing early-stage osteonecrosis of the femoral head (ONFH) by extracting features from multiple MRI sequences and constructing predictive models.
Materials And Methods: We conducted a retrospective review, collected MR images of early-stage ONFH (102 from institution A and 20 from institution B) and healthy femoral heads (102 from institution A and 20 from institution B) from two institutions. We extracted radiomics features, handled batch effects using Combat, and normalized features using z-score.
Background: Perihepatic fluorouracil encapsulated lesions (FELs) can result in potentially confusing computed tomography (CT) and magnetic resonance imaging (MRI) features in postoperative examinations of gastrointestinal tumors. This retrospective study aimed to summarize the typical imaging features of FELs and determine the best imaging modality to distinguish FELs from liver metastases for junior residents.
Methods: Patients with FELs who had undergone gastrointestinal tumor surgery in Tongji Hospital from January 2016 to June 2022 were evaluated.
