Background: This study presents the first report in the same patients on the time efficiency of surface registration as well as the navigational accuracy using optic and electromagnetic tracking systems.
Methods: Thirty patients with bilateral chronic paranasal pansinusitis underwent endoscopic sinus surgery. After surface registration, the surgeries were performed on one side using optic navigation guidance and on the other side using electromagnetic navigation guidance. The intraoperative measurements performed included the time taken for the surface registration and surgical procedure on each side, as well as the navigation errors at the different locations.
Results: The time for surface registration was significantly longer in the optic navigation group than the electromagnetic group. A comparison of the navigation errors along the 3 axes showed that the deviation in the medial-lateral direction was significantly less than that in the anterior-posterior and cranial-caudal directions in the optic navigation group as well as the electromagnetic group.
Conclusions: The procedure for surface registration in both optic and electromagnetic guidance is efficient and convenient. The accuracy of both navigation systems is comparable and within acceptable ranges for clinical use. In addition, the best accuracy was measured in the medial-lateral direction compared with the other two axes.

Background: Catheter ablation (CA) is an effective therapeutic option for patients with symptomatic atrial fibrillation (AF). Previous studies have reported silent cerebral lesions (SCLs) detected by magnetic resonance imaging (MRI) after different CA techniques; however, the results were controversial. Therefore, we performed this network meta-analysis (NMA) to assess the incidence of SCLs after cryoballoon, hotballoon, laserballoon, and radiofrequency ablation (RFA).

Conversely, light field (LF) reconstruction provides satisfactory low-frequency geometry but sacrifices spatial resolution, impacting high-frequency detail quality. To tackle these challenges, we propose a photometric stereoscopic light field measurement (PSLFM) scheme that harnesses the strengths of both methods.

Introduction: Post-stroke movement disorders are common, especially upper limb dysfunction, which seriously affects the physical and mental health of stroke patients. With the continuous development of intelligent technology, robot-assisted therapy has become a research hotspot in the upper limb rehabilitation of stroke patients in recent years. Many scholars have also integrated robot-assisted therapy with other interventions to improve rehabilitation outcomes.

Background Vitamin D and calcium are necessary for tooth health, and a lack of these can cause substantial changes. Dental caries, or tooth decay, is a common childhood illness that causes pain, difficulty chewing, and a lower quality of life. There is a scarcity of research on the correlation between vitamin D and calcium levels and dental caries risk among children in western Maharashtra.

Background: The purpose of this study was to evaluate the validity of near-infrared light reflection for detecting different depths of proximal caries in posterior teeth and to compare it with commonly used clinical oral examinations and bitewing radiography images.
Methods: Twenty-six patients with a total of 516 proximal surfaces were included in this study. The ground truth of the proximal caries was determined through a consensus reached by two experienced dentists after an intraoral examination assisted by bitewing radiographs.
