AXIN1/MYC Axis Mediated the Osimertinib Resistance in EGFR Mutant Non-Small Cell Lung Cancer Cells.
Osimertinib, a promising and approved third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), is a standard strategy for EGFR-mutant non-small cell lung cancer (NSCLC) patients. However, developed resistance is unavoidable, which reduces its long-term effectiveness. In this study, RNA sequencing was performed to analyze differentially expressed genes (DEGs). ⋯ Furthermore, we demonstrated that AXIN1 upregulated the expression of C-MYC and mediated the acquired resistance of EGFR mutant NSCLC cells to osimertinib in vitro. In conclusion, AXIN1 affected the sensitivity of EGFR mutant NSCLC to osimertinib via regulating C-MYC expression in vitro. Targeting AXIN1/MYC signaling may be a potential new strategy for overcoming acquired resistance to osimertinib.

Case ReportsAnamorelin Induced Acute Hyperglycemia in a Patient with Advanced Pancreatic Cancer and Diabetes: A Case Report.
Anamorelin (ANAM) is a novel ghrelin receptor agonist for the treatment of cancer cachexia. In clinical trials of ANAM, glucose metabolism disorders as adverse effects were relatively frequent, however, when and how they occur remains unclear. Moreover, the safety in patients with pancreatic cancer and/or diabetes has not been clarified because most previous studies focused on patients with non-small cell lung cancer and had excluded patients with poorly controlled diabetes. ⋯ Increasing the insulin dose failed to control hyperglycemia adequately, but the hyperglycemia ameliorated quickly after ANAM discontinuation. The continuous glucose monitoring (CGM) revealed that the sensor glucose levels had remained in the high range throughout the day during ANAM administration despite using 1.5 times more insulin. Our report is one of the few that describe the details of ANAM-induced hyperglycemia and provides important information for the safe and effective use of ANAM.

Randomized Controlled TrialA Specific, Measurable, Achievable, Relevant, Timed (SMART) Nursing Project Reduces Anxiety, Depression, and Post-Traumatic Stress Disorder in Parents of Childhood or Adolescent Osteosarcoma Patients.
Specific, measurable, achievable, relevant, timed (SMART) principle improves the nursing utility by setting individual goals for participants and helping them to achieve these goals. Our study intended to investigate the impact of a SMART nursing project on reducing mental stress and post-traumatic stress disorder (PTSD) in parents of childhood or adolescent osteosarcoma patients. In this randomized, controlled study, 66 childhood or adolescent osteosarcoma patients and 126 corresponding parents were enrolled and divided into SMART or normal care (NC) groups at a 1:1 ratio. ⋯ NC group. By subgroup analyses, the SMART nursing project showed better impacts on decreasing anxiety, depression, and PTSD in parents with an undergraduate education or above than in those with a high school education or less. Conclusively, SMART nursing project reduces anxiety, depression, and PTSD in parents of childhood or adolescent osteosarcoma patients, which is more effective in those with higher education.
