Department of Radiological Technology, Fujieda Municipal General Hospital, Fujieda, JPN.
Purpose This study aimed to clarify which positions are beneficial for patients with pathological lung diseases, such as acute respiratory distress syndrome, by obtaining lung ventilation and deformable vector field (DVF) images using Deformable Image Registration (DIR). Methods Thirteen healthy volunteers (5 female, 8 male) provided informed consent to participate to observe changes in normal lungs. DIR imaging was processed using the B-spline algorithm to obtain BH-CTVI (inhale, exhale) in four body positions (supine, prone, right lateral, left lateral) using DIR-based breath-hold CT ventilation imaging (BH-CTVI).

Recent investigations into radiation-induced side effects have focused on understanding the physiopathological consequences of irradiation on late-responding tissues like the spinal cord, which can lead to chronic progressive myelopathy. Proton therapy, an advanced radiation treatment, aims to minimize damage to healthy tissues through precise dose deposition. However, challenges remain, particularly regarding the variation in dose distribution, characterized by maximum deposition at the end of the proton range, known as the distal fall-off of a spread-out Bragg peak.

Psoriasis is a chronic inflammatory skin condition characterized by hyperproliferation of keratinocytes and immune dysregulation. Narrow band ultraviolet B (NB-UVB) phototherapy is a common treatment for psoriasis due to its efficacy and safety profile. NOD2 is an intracellular pattern recognition receptor involved in immune responses and inflammation, and its expression is elevated in psoriatic skin.

Background: Breast cancer, a potential traumatic stressor, may be accompanied by positive changes, such as post-traumatic growth (PTG), which may allow patients to overcome this stressful event more easily. Our aim was to identify factors associated with PTG in breast cancer survivors (BCSs).
Methods: We conducted a cross-sectional study in Seintinelles volunteers who answered online questionnaires.
