Comparison of two 3D scanning software to identify facial features: a prospective instrument to predict difficult airway.

BACKGROUND: Clinical airway assessment has limited predictive ability to anticipate difficult airway. Three-dimensional (3D) technologies have emerged in medicine as valuable tools in different settings including innovation and surgical planning. Three-dimensional facial scanning could add value to clinical measurements and two-dimensional models to assess the airway. However, commonly used high-fidelity scans are expensive. This study aims to compare the accuracy of the measurements made by the Scandy Pro app as a cost-effective alternative to high-fidelity scans made by the Artec Space Spider. We also aim to evaluate the interobserver variability for the measurements performed with Scandy Pro. MATERIALS AND METHODS: We conducted a cross-sectional, comparison study on 10 healthy volunteers. Four observers measured 720 distances and 400 using both Scandy Pro and Artec Space Spider facial scans. Wilcoxon test was used for group-group comparison. RESULTS: Comparison of both instruments showed no difference in angle or distance measurements. The percentage error (measurement difference between the two devices) exhibited by one of the observers was significantly different compared with the other three observers; however, the magnitude of this individual deviation did not affect the overall percentage error. The overall error for Scandy Pro was 5.5% (3.9% and 6.7% for angles and distances, respectively). CONCLUSION: Three-dimensional facial scanning with Scandy Pro is an accurate tool that can be a cost-effective alternative to high-fidelity scans produced by the Artec Space Spider.

A Comprehensive Research Schema for the Characterization of Aortic Aneurysms.

A robust, accurate, and standardized approach to measurement of the aorta is critical to improve the predictive accuracy of these aortic measurements, and to investigate other aortic imaging biomarkers. Developing a comprehensive and generic schema for characterization of the aorta to enable investigators to standardize data that are collected across all aorta research. A systematic review of the literature was conducted to identify and assess schemata of aortic measurement and description. The schemata were reported and discussed to guide the synthesis of a comprehensive schema. We propose the International College of Angiology Aortic Research Schema as a comprehensive design that fills the gaps left behind by previously reported schemata. It is intended to be applicable for all clinically relevant purposes, including endograft development for aneurysm repair and for the accurate characterization of the aortic anatomy. This schema divides the aorta into 14 segments and 2 sections (thoracic and abdominal aortas). The segmentation proposed can be used in addition to specific measurements taken for any aneurysm including the neck, and maximal and minimal diameters of the aneurysm.

BioImages is the BioCommunications Association's (BCA) annual visual media competition, featuring images from the life sciences and medicine. The exhibition showcases the finest still images, illustrations, and graphic media, as well as interactive and motion media. Entries for BCA's 2022 Salon were evaluated by a distinguished panel of judges based on the work's intent, execution, design, and overall impact.

Faculty Perspective on Interprofessional Education Competencies: Respiratory Therapy Compared to Other Allied Health Professions.

BACKGROUND: Interprofessional Education (IPE) provides a framework for collaborative education between health care specialties to improve patient care. In 2010, the Interprofessional Education Collaborative Expert Panel established the competencies of communication, ethics, roles and responsibilities, and teams and teamwork. Studies have assessed knowledge and attitudes about IPE in several allied health educational programs including respiratory therapy (RT). METHODS: We compared RT faculty to athletic training (AT), nutrition (NT), occupational therapy (OT), physical therapy (PT), and dental hygiene (DH) faculty. Faculty were asked to rank the IPE competencies according to importance. RESULTS: RT faculty ranked communication first, then teams and teamwork, roles and responsibilities, and last ethics. A Kruskal-Wallis Dwass-Steel-Chritchlow-Fligner pairwise analysis showed statically significant differences among allied health faculty rankings of IPE competencies. In communication, RT faculty responded statistically higher than AT (P < .001), DH P < .001), NT P < .001), and OT (P = .003). In ethics, RT faculty responded statistically lower than DH (P < .001), NT (P = .01), and PT (P < .001). In roles and responsibilities, RT faculty responded statistically higher than AT (P = .007) and OT (P < .001). In teamwork, RT faculty responded statistically higher than AT (P = .02), DH (P < .001), OT (P = .002), and PT (P < .001). CONCLUSIONS: RT faculty who teach at different degree levels (associate's degree programs vs bachelor's and master's degree programs) had the same ranking of competencies, but they had a statistically significant difference for teamwork, with associate's degree faculty ranking teamwork lower than bachelor's and master's degree faculty.

Aesthetics in Thyroid Surgery: The Patient Perspective.

Objectives To define characteristics that influence patient perceptions of thyroidectomy scar cosmesis. Study Design Prospective cohort study. Setting Tertiary endocrine surgery practice in an academic medical center. Subjects and Methods Institutional review board-approved trial in which 136 subjects were recruited from a population of patients being seen for either thyroid or sinus surgery and evaluated standardized photographs, superimposed with computer-generated thyroidectomy scars of varying lengths (2, 4, and 6 cm) and widths (1 and 2 mm), and graded their perception of the scars using the observer scar assessment scale (OSAS) domains of the patient and observer scar assessment scale. Results There were 69 subjects in the thyroid group and 67 in the nonthyroid group. Controlling for width, longer scars were perceived as worse than shorter scars; controlling for length, thicker scars were perceived as worse than thinner scars ( P < .01). Beyond 2 cm, thick scars were judged to be worse than thin scars, even when they were shorter. There was no difference in the mean overall OSAS scores between surgery, sex, or age groups. Nonwhites tended to judge scars as being worse than whites did ( P < .01). Conclusion As expected, patients of all demographics prefer shorter scars compared with longer scars and thinner scars over thick scars. Ethnic differences in scar perception were identified and deserve additional study. Surgeons should endeavor to perform thyroid surgery through the smallest incision that allows the operation to be performed safely to minimize the cosmetic impact of the operation.

The Feasibility of Simultaneous Orthogonal Plane Imaging with Tilt for Short-Axis Evaluation of the Pulmonic Valve by Transesophageal Echocardiography.

Simultaneous orthogonal plane imaging with tilt enables the display of two 2D, real-time images and the evaluation of structures that cannot be seen by conventional single-plane transesophageal echocardiographic (TEE) imaging. After a step-wise examination protocol, we used simultaneous orthogonal plane imaging to obtain the short-axis view of the pulmonic valve (PV) and assessed flow in both images simultaneously using color Doppler imaging in 100 consecutive patients undergoing intraoperative TEE. Our goals were to assess the ability of this technique to visualize all 3 leaflets of the PV, assess feasibility of planimetry to measure valve area, and assess flow using color Doppler imaging. All study images were obtained by anesthesiologists who are diplomates in Advanced Perioperative Transesophageal Echocardiography. All 3 leaflets of the PV were successfully visualized in the short-axis view in 65% of cases, 2 leaflets were visualized in 32% of cases, and only 1 leaflet could be imaged in 3%. The flow across the valve could be evaluated using color Doppler imaging in all cases. Planimetry for valve area was possible when all 3 leaflets were seen. It is important to inspect the PV during a routine TEE examination; however, the orientation of the PV in respect to the esophagus makes this evaluation challenging. We present a simple protocol to evaluate the PV in long-axis and short-axis views simultaneously that can potentially help evaluate for pathologies involving the PV.
