“…2a . Flexibility is essential for NP swabs as they must bend and penetrate far into the nasopharyngeal cavity to collect sufficient samples 22 , 26 , 31 , 32 . Figure 2b demonstrates that the reactive bending force (platform force) of the microlattice NP swab is up to 7 times less than that of the commercial NP swabs, and the flexibility (the reciprocal of the slope) of the microlattice NP swabs are up to ~11 times of that of the commercial NP swab.…”

Nasopharyngeal (NP) swab is one of the most effective sampling devices for clinical specimens. However, commercial NP swabs often release samples through diluents, lowering analyte concentration and causing inaccurate detections. Here, we developed 3D-printed open-cell microlattice NP swabs with user-friendly high-efficiency controlled sample release (CR) mode. Compared with traditional NP swabs, our microlattice NP swabs show higher (~7–11 times) flexibility, larger (~2.3 times) and customizable release volume, higher (dozens to thousands of times) release concentration, high recovery efficiency (~100%), and the ability to quantify analyte levels. Our microlattice NP swabs have been thus demonstrated to improve the sensitivity and accuracy of antibody detection experiments using rapid detection kits. This study offers a promising approach to enhance sensitivity and accuracy in clinical specimen detections, and is beneficial to inspire the design of a wider range of biomedical devices based on 3D-printed microlattice metamaterials.

“…Current advancement in the fields of tissue engineering, material sciences, and additive manufacturing provide the opportunity to augment approaches to reconstruction of head and neck structures. In fact, 3D printing has been applied to surgical training in otolaryngology, an example being the use of 3D printed temporal bones for surgical simulation, [4,97] medical teaching, [98,99] as well as customized surgical planning. [100][101][102][103] Moreover, clinical applications of 3D printing in otolaryngology have included the successful treatment of severe airway malacia using a 3D printed, personalized PCL external airway splint.…”

The evolution of tissue engineering and 3D bioprinting has allowed for increased opportunities to generate musculoskeletal tissue grafts that can enhance functional and aesthetic outcomes in otolaryngology—head and neck surgery. Despite literature reporting successes in the fabrication of cartilage and bone scaffolds for applications in the head and neck, the full potential of this technology has yet to be realized. Otolaryngology as a field has always been at the forefront of new advancements and technology and is well poised to spearhead clinical application of these engineered tissues. In this review, current 3D bioprinting methods are described and an overview of potential cell types, bioinks, and bioactive factors available for musculoskeletal engineering using this technology is presented. The otologic, nasal, tracheal, and craniofacial bone applications of 3D bioprinting with a focus on engineered graft implantation in animal models to highlight the status of functional outcomes in vivo; a necessary step to future clinical translation are reviewed. Continued multidisciplinary efforts between material chemistry, biological sciences, and otolaryngologists will play a key role in the translation of engineered, 3D bioprinted constructs for head and neck surgery.

“…Literature has demonstrated that the use of three-dimensional (3D) printed models or manikins to train healthcare workers on nasopharyngeal tests was useful and improved both confidence and comfort in performing the tests. [16][17][18] Limited studies have highlighted educational models for teaching specimen collection for infectious diseases in pharmacy education. 2,4,19 McKeirnan and colleagues describe implementation of POCT content for second year pharmacy students as part of a weeklong 2-credit hour required course.…”

Introduction: A point-of-care testing (POCT) certificate was implemented in a required pharmacy skills-based course. The purpose of this study was to evaluate the impact of manikins on student confidence in performing POCT for infectious diseases. Innovation: Manikins were used to train second-year pharmacy students on nasal swabs, throat swabs, and oral fluid swabs. Student skills were assessed on manikins first, then on a peer. Proficiency was defined as a score of 90% or higher. Students completed a pre- and post-training survey regarding their confidence performing swabs. Student confidence was based on Likert style responses (i.e., ‘Strongly Disagree’ [score: 1], to ‘Strongly Agree’ [score: 5]) performing the swabs. Median change in confidence was calculated using quantile regression. Findings: All students (n=63) demonstrated proficiency in performing swabs. Median confidence for nasal, throat, and oral fluid swabs changed by 2.0 (95% CI: 1.5, 2.5), 2.0 (95% CI: 1.5, 2.5), and 2.0 (95%CI: 1.3, 2.7), respectively. The majority of students reported time spent practicing was adequate for the nasal (n=51, 81%), throat (n=51, 81%), and oral fluid swab (n=59, 94%). All participating students reported manikins to be moderately (n=17, 27%) or extremely (n=46, 73%) valuable, and all students rated their overall experience with manikins as positive (n=63, 100%). Student comments revealed manikins helped to visualize anatomy, practice skills without peer discomfort, and minimize risk during the COVID-19 pandemic. Conclusion: This study demonstrated that inclusion of practice on manikins increased student confidence in performing POCT for infectious diseases. In addition, the majority of students indicated that the use of manikins was valuable to their learning and reported feeling prepared to perform POCT in practice after using the manikins.
