ABSTRACT
CASE DESCRIPTION: A five-year-old male with spastic quadriplegia cerebral palsy and an expressive communication disorder presented because the family desired liberalization of diet. The diet consisted of pureed solids and no liquids due to deficits identified on bedside swallow evaluation; further dysphagia assessment had not been obtained due to significant procedural anxiety. Comprehensive approaches were taken involving premedication with buspirone, desensitization, distraction, and positive reinforcement. The fluoroscopic swallow study was successfully completed, and the patient's diet was upgraded to include moderately thickened liquids. DISCUSSION: Procedural anxiety management in special populations is not well-researched. The lack of definitive recommendations regarding these issues increases the difficulty of managing these patients. This case highlights one successful approach to addressing individual needs using widely-available pharmacologic and environmental techniques. Additionally, this case reinforces the need to identify underlying causes for procedural anxiety and involve an interdisciplinary team. CONCLUSIONS: Attempts should be made to identify factors driving procedural anxiety. After discussing with the patient and family, relevant information should be relayed to staff with an open-ended invitation to propose ideas. While not all hospitals have equivalent resources, concerns related to unfamiliarity, underlying anxiety, and locus of control can be addressed with limited resource utilization, as demonstrated in this case.
ABSTRACT
Surgical meshes composed of bioinert polymers such as polypropylene are widely used in millions of hernia repair procedures to prevent the recurrence of organ protrusion from the damaged abdominal wall. However, post-operative mesh infection remains a significant complication, elevating hernia recurrence risks from 3.6% to 10%, depending on the procedure type. While attempts have been made to mitigate these infection-related complications by using antibiotic coatings, the rise in antibiotic-resistant bacterial strains threatens their effectiveness. Bioactive glass-ceramics featuring noble metals, notably silver nanoparticles (AgNPs), have recently gained traction for their wide antibacterial properties and biocompatibility. Yet, conventional methods of synthesizing and coating of such materials often require high temperatures, thus making them impractical to be implemented on temperature-sensitive polymeric substrates. To circumvent this challenge, a unique approach has been explored to deposit these functional compounds onto temperature-sensitive polypropylene mesh (PP-M) surfaces. This approach is based on the recent advancements in cold atmospheric plasma (CAP) assisted deposition of SiO2 thin films and laser surface treatment (LST), enabling the selective heating and formation of functional glass-ceramic compounds under atmospheric conditions. A systematic study was conducted to identify optimal LST conditions that resulted in the effective formation of a bioactive glass-ceramic structure without significantly altering the chemical and mechanical properties of the underlying PP-M (less than 1% change compared to the original properties). The developed coating with optimized processing conditions demonstrated high biocompatibility and persistent antibacterial properties (>7 days) against both Gram-positive and Gram-negative bacteria. The developed process is expected to provide a new stepping stone towards depositing a wide range of functional bioceramic coatings onto different implant surfaces, thereby decreasing their risk of infection and associated complications.

In this article, we discuss Beauchamp and Childress's treatment of the issue of moral status. In particular, we (1) introduce the five different perspectives on moral status that Beauchamp and Childress consider in Principles of Biomedical Ethics and explain their alternative to those perspectives, (2) raise some critical questions about their approach, and (3) offer a different way to think about one of the five theories of moral status (the theory based on human properties) that is more in line with what we believe some of its leading advocates affirm.
