Article Synopsis
  • Neurosurgery requires not only technical skills but also non-technical skills (NTSs) to achieve mastery, highlighting the importance of both in surgical practice.
  • An international survey of 372 neurosurgeons indicates that qualities like attention to detail, humility, and self-awareness are vital for surgical precision and effective teamwork.
  • The study advocates for integrated training that includes simulations and mentorship to enhance NTSs, while also stressing the need for research aimed at improving educational methods, especially in regions with unequal access to neurosurgical care.

Introduction: Surgical training traditionally adheres to the apprenticeship paradigm, potentially exposing trainees to an increased risk of complications stemming from their limited experience. To mitigate this risk, augmented and virtual reality have been considered, though their effectiveness is difficult to assess.

Research Question: The PASSION study seeks to investigate the improvement of manual dexterity following intensive training with neurosurgical simulators and to discern how surgeons' psychometric characteristics may influence their learning process and surgical performance.

An efficient photorefractive effect triggered by pyroelectricity is demonstrated in slab waveguides constituted of magnesium oxide (MgO)-doped LiNbO film on insulator. A microwatt-level continuous wave guided at 532 nm is self-trapped to form a 10 µm FWHM beam triggered by only a few degrees of temperature increase of the sample. A fast self-focusing response time on the order of milliseconds is measured for milliwatts of injected beam, more than two orders of magnitude faster than in the undoped LiNbO film.

Article Synopsis
  • The study examines the effectiveness and feasibility of rectal-sparing treatments for rectal cancer patients who showed a significant response after neoadjuvant therapy, although there is ongoing debate about their effectiveness.
  • In a multicenter study involving 178 patients, around 80.9% were able to preserve their rectum while showing promising survival rates over three years, including an overall survival rate of 80.6% and a stoma-free survival rate of 95%.
  • The findings suggest that for rectal cancer patients who achieve a major or complete response to neoadjuvant therapy, rectal preservation is possible in most cases without negatively affecting patient outcomes.
