Aim: The aim of this study was to determine the sagittal position of the upper incisor considering Andrews' analysis based on the position of the forehead in Peruvian individuals with different skeletal relationships.
Materials And Methods: This retrospective, cross-sectional study included 212 lateral head radiographs of Peruvian individuals (males: 85, mean age 21.38 ± 6.88, and females: 127, mean age 21.18 ± 6.95), with different skeletal relationships (Class I group = 96, Class II group = 57, Class III group = 59). The values of the ANB, SNA, SNB angles as well as the forehead anterior limit line (FALL) and goal anterior limit line (GALL) points were identified in the radiographs, and then a vertical line was drawn in each point to determine if the upper incisor was positioned forward (protruded), backward (retruded) or within (adequate) these lines. Two trained and calibrated investigators performed all the measurements. The Chi-square test was used to evaluate associations. A -value < 0.05 was considered statistically significant.
Results: Overall, the sagittal position of the upper incisor showed a significant association with the sagittal skeletal relationship ( = 0.001). The upper incisors showed an adequate position (41.7%), protruded position (56.10%), and retruded position (42.40%), for Class I, II, and III skeletal relationships, respectively, as highest percentages in each Class. Statistical significance was found for females only ( = 0.005).
Conclusion: Skeletal Class I mainly showed an adequate position of the upper central incisor, whereas for Class II a protruded position was most frequently found, and Class III presented a retruded position.
Clinical Significance: Andrews' analysis based on the position of the forehead in Peruvian individuals is a valuable tool for orthodontic diagnosis.

Background: The insertion of a tracheostomy is an established technique used to wean patients off ventilatory support, manage secretions in complex conditions, and as a potentially life-saving procedure to bypass upper airway obstruction. Life-threatening complications during aftercare are not uncommon and may be influenced by a lack of education of carers or healthcare providers of children and young people living with a tracheostomy. Education programmes designed and supported by the National Tracheostomy Safety Project are effective, but resources are not available to educate the workforce at scale.

A boy with bilateral congenital anomalies of the upper extremities with transverse absence of the left arm (agenesis) and absence of right thumb (disgenesis), fixed elbow in extension due to humeroradial synostosis thought that the humerus was intact. His wrist could move passively with 50° flexion, 0° extension, and 70° radial deviation. The other 4 fingers were intact, 4-5 metatarsal bones were in synostosis, and the fifth finger was clinodactyly.

In weightlifting, quantitative kinematic analysis is essential for evaluating snatch performance. While marker-based (MB) approaches are commonly used, they are impractical for training or competitions. Markerless video-based (VB) systems utilizing deep learning-based pose estimation algorithms could address this issue.

Background And Purpose: Radiotherapy for paediatric posterior fossa tumours may cause complications in the brainstem and upper spinal cord due to high doses. With proton therapy (PT) this risk may increase due to higher relative biological effectiveness (RBE) from elevated linear energy transfer (LET). This study assesses variations in LET in the brainstem and spinal cord in proton treatment plans from European centres.

Objectives: Although exercise-induced vascular adaptations have been extensively reported in racket sports athletes, the applicability of these findings to athletes in other overhead sports is unclear. This study aimed to investigate exercise-induced vascular adaptations in college male baseball players. Furthermore, since the training frequency of the upper arm may differ by baseball playing position, this study also focused on playing position-specific differences in brachial arterial adaptations.
