AI Article Synopsis
- The study compares computer-assisted surgery (CAS) with 3D navigation to conventional techniques for pedicle screw insertion in spine surgeries.
- Significant differences were noted in accuracy, with CAS showing higher misplacement rates during percutaneous procedures but better accuracy in open surgeries.
- While surgical times were longer for CAS compared to conventional methods, radiation exposure was lower for percutaneous surgeries but higher for open surgeries using 3D navigation.
Article Abstract
Purpose: We report a single-center, prospective, randomized study for pedicle screw insertion in opened and percutaneous spine surgeries, using a computer-assisted surgery (CAS) technique with three-dimensional (3D) intra-operative images intensifier (without planification on pre-operative CT scan) vs conventional surgical procedure.
Material And Method: We included 143 patients: Group C (conventional, 72 patients) and Group N (3D Fluoronavigation, 71 patients). We measured the pedicle screw running time, and surgeon's radiation exposure. All pedicle runs were assessed according to Heary by two independent radiologists on a post-operative CT scan.
Results: 3D Fluoronavigation appeared less accurate in percutaneous procedures (24 % of misplaced pedicle screws vs 5 % in Group C) (p = 0.007), but more accurate in opened surgeries (5 % of misplaced pedicle screws vs 17 % in Group C) (p = 0.025). For one vertebra, the average surgical running time reached 8 min in Group C vs 21 min in Group N for percutaneous surgeries (p = 3.42 × 10(-9)), 7.33 min in Group C vs 16.33 min in Group N (p = 2.88 × 10(-7)) for opened surgeries. The 3D navigation device delivered less radiation in percutaneous procedures [0.6 vs 1.62 mSv in Group C (p = 2.45 × 10(-9))]. For opened surgeries, it was twice higher in Group N with 0.21 vs 0.1 mSv in Group C (p = 0.022).
Conclusion: The rate of misplaced pedicle screws with conventional techniques was nearly the same as most papers and a little bit higher with CAS. Surgical running time and radiation exposure were consistent with many studies. Our work hypothesis is partially confirmed, depending on the type of surgery (opened or closed procedure).

SAILOR: perceptual anchoring for robotic cognitive architectures.
Sci Rep
January 2025
Robotics Group, Department of Mechanic Engineering, Computer and Aerospace Sciences, University of León, 24006, León, Spain.
Symbolic anchoring is an important topic in robotics, as it enables robots to obtain symbolic knowledge from the perceptual information acquired through their sensors and maintain the link between that knowledge and the sensory data. In cognitive-based robots, this process of transforming sub-symbolic data generated by sensors to obtain and maintain symbolic knowledge is still an open problem. To address this issue, this paper presents SAILOR, a framework for symbolic anchoring integrated into ROS 2.

Introduction And Objective: Research on runners is most often conducted in the context of sports motivation using the adaptation of the Motivations of Marathoners Scale (MOMS) questionnaire, which, however, does not measure aspects related to tourism, nature or socio-cultural aspects. The aim of the study was to create a Polish adaptation of the Sports Tourism Motivation Scale (STMS) for athletes, especially runners, which, for the first time, enables the examination of socio-cultural and tourism-related aspects among them in Poland.
Material And Methods: To conduct the adaptation, the STMS tool was tested among 100 individuals who engage in running: 50 participating in a city-organized running event around cultural monuments (2022 Poznań Marathon) and another 50 individuals running on non-urban routes - in a national park (2022 Łemkowyna Ultra-Trail), exemplified by a nature-surrounded running activity.

Introduction: Considering the theory of self-determination and its relationship with human motivation and the play-based approach (PBA), a training program is implemented in young middle and long-distance running athletes with play activities (simple tasks with rules in a ludic mood). The objectives were (1) to analyze the effects of a PBA on the autonomy support interpersonal teaching style (ASITS) perceived by athletes, the psychological variables of satisfaction of basic psychological needs, motivation, enjoyment and intention to continue practicing athletics and depending on sex, and (2) know the athletes' perception of this methodology after the intervention.
Method: Quasi- experimental design with a sample of 50 athletes (27 women and 23 men) with 17.

We aimed to analyze sex differences in time-limited ultramarathon participation, while also identifying trends in participation, age, and performance across different formats of events, from 1990 to 2020. This is an exploratory study, using data obtained from the official event web pages. We downloaded information regarding the year of the event, athletes' year of birth, sex, race event, ranking, and mean running speed (km/h).

Introduction: The inability to sense force applied to tissue is suggested as a limitation to robotic-assisted surgery (RAS). This pre-clinical study evaluated the impact of a novel force feedback (FFB) technology, integrated on a next-generation robotic system that allows surgeons to sense forces exerted at the instrument tips, on suturing performance by novice surgeons during RAS.
Methods: Twenty-nine novice surgeons (< 50 RAS cases in the last 5 years) were randomized into two groups with (n = 15) or without (n = 14) FFB sensing.
