Background: On optical coherence tomography (OCT) scans of the optic nerve head, peripapillary hyperreflective ovoid mass-like structures (PHOMS) are sometimes seen as a sign of axonal distension. The phenomenon has been reported more frequently in myopic subjects. We investigated PHOMS-prevalence in a myopic pediatric cohort, associated risk factors, and PHOMS development over 18 months during low-dose atropine treatment.

However, little is known about how facilitators recognise and respond to students' emotions during simulations. This study aims to understand how simulation facilitators perceive and respond to students' emotions during simulation-in order to optimise learning.

- Dual immune checkpoint blockade (ICB) using CTLA4 and PD-(L)1 inhibitors shows improved anti-tumor effectiveness and immune toxicity compared to PD-(L)1 inhibitors alone in advanced non-small-cell lung cancer (NSCLC) patients.
- Patients with mutations in STK11 and/or KEAP1 genes benefit more from the combination treatment compared to those receiving only PD-(L)1 inhibitors, as shown in the POSEIDON trial.
- The loss of KEAP1 serves as a strong predictor for the success of dual ICB, as it leads to a more favorable outcome by changing the tumor's immune environment to better engage CD4 and CD8 T cells for anti-tumor activity. *
The retina transforms patterns of light into visual feature representations supporting behaviour. These representations are distributed across various types of retinal ganglion cells (RGCs), whose spatial and temporal tuning properties have been studied extensively in many model organisms, including the mouse. However, it has been difficult to link the potentially nonlinear retinal transformations of natural visual inputs to specific ethological purposes.

The aim of this study was to evaluate artificial intelligence (AI) generated contours and inter-observer target variation among radiotherapy technicians in cone-beam CT (CBCT) guided oART of bladder cancer.
Materials And Methods: For each of 10 consecutive patients treated with oART for bladder cancer, one CBCT was randomly selected and retrospectively included.
