[Mentoring in a hospital setting: where do we stand?].

Mentoring has long been a cornerstone of medical training, facilitating knowledge transfer and supporting the professional progression of learners. Today, it could play a crucial role in the professional fulfillment of young doctors navigating an increasingly complex and demanding hospital environment. However, current mentoring programs appear under-powered and hampered by significant organizational challenges.

Risk Behavior and Reciprocity of Organ Donation Attitudes in Young Men.

Background: Lack of donor organs remains a major obstacle in organ transplantation. Our aim was to evaluate (1) the association between engaging in high-risk recreational activities and attitudes toward organ donation and (2) the degree of reciprocity between organ acceptance and donation willingness in young men.

Methods: A 17-item, close-ended survey was offered to male conscripts ages 18 to 26 years in all Swiss military conscription centers.

Monte Carlo based beam model using a photon MLC for modulated electron radiotherapy.

Purpose: Modulated electron radiotherapy (MERT) promises sparing of organs at risk for certain tumor sites. Any implementation of MERT treatment planning requires an accurate beam model. The aim of this work is the development of a beam model which reconstructs electron fields shaped using the Millennium photon multileaf collimator (MLC) (Varian Medical Systems, Inc.

Dosimetric properties of an amorphous silicon EPID for verification of modulated electron radiotherapy.

Purpose: To investigate the dosimetric properties of an electronic portal imaging device (EPID) for electron beam detection and to evaluate its potential for quality assurance (QA) of modulated electron radiotherapy (MERT).

Methods: A commercially available EPID was used to detect electron beams shaped by a photon multileaf collimator (MLC) at a source-surface distance of 70 cm. The fundamental dosimetric properties such as reproducibility, dose linearity, field size response, energy response, and saturation were investigated for electron beams.

Acute and late toxicity in prostate cancer patients treated by dose escalated intensity modulated radiation therapy and organ tracking.

Background: To report acute and late toxicity in prostate cancer patients treated by dose escalated intensity-modulated radiation therapy (IMRT) and organ tracking.

Methods: From 06/2004 to 12/2005 39 men were treated by 80 Gy IMRT along with organ tracking. Median age was 69 years, risk of recurrence was low 18%, intermediate 21% and high in 61% patients.
