Pancreatic adenocarcinoma (PAAD) is a common and highly malignant tumor. The identification of prognostic biomarkers for PAAD could provide invaluable information for clinical treatment. AMP-activated protein kinase family member 5 (ARK5) is a member of the AMPK family that mediates the migration of PAAD cells. In the present study,ARK5expression was evaluated using bioinformatics analysis in public datasets from The Cancer Genome Atlas. The expression levels of ARK5 in PAAD tumor tissue were significantly increased, compared with matched non-cancerous tissues.ARK5target genes were then predicted and Gene Ontology Biological Processes, Kyoto Encyclopedia of Genes and Genomes pathway analysis and Reactome gene sets were used to determine the functions associated with the target genes. A protein-protein interaction network was also constructed to find out the node genes and observe their association with the overall survival rate of PAAD. A total of nine node genes were identified in the PPI network, of which six were significantly upregulated in PAAD tissue, compared with matched normal tissue. The prognostic value of each node gene was evaluated by comparing the overall survival in patients with PAAD stratified according to the expression levels of these genes. Overall survival was significantly reduced in patients with high polo-like kinase-1 (PLK1) or protein phosphatase 1 catalytic subunit beta (PPP1CB) expression, compared with patients with low expression of these genes. To further evaluate the relationship between PAAD andARK5, ARK5 immunohistochemical staining was performed in a tissue microarray consisting of 112 tumor samples from patients with PAAD and adjacent normal tissue samples. ARK5 protein expression in PAAD tissue was markedly increased, compared with non-cancerous tissue (P=7.631x10(-11)). Moreover, ARK5 protein levels were associated with N stage (P=0.018). The overall survival of patients with PAAD with high ARK5 protein expression levels was reduced (P=0.014), compared with patients with low expression. In conclusion, these findings suggested thatARK5may represent an independent prognostic indicator of PAAD.

The use of telemedicine in clinical care has grown significantly in the last few years and has only increased during the COVID-19 pandemic. Given that many physicians will be expected to deliver virtual care moving forward, it is important for medical students to gain exposure via this modality during their clinical training. Many medical schools are actively working to integrate students into telemedicine. This article aims to provide guidance for readers incorporating medical students in telemedicine visits at an institutional or departmental level. This article covers essential topics such as coordinating key stakeholders, conducting needs assessments, addressing technological or software considerations, and creating appropriate workflows for students and physicians.
