Design And Application

This paper discusses the design and application of magnetic-based position tracking in surgical trainers. The utilization of magnetic-based position tracking in Laparoscopic Trainers provides a cost-effective solution to the next generation of medical education, training and evaluation. The utilization of 3D printed parts as well as off the shelf electronics allows us to maximize accuracy while minimizing design cost. Our current design costs less than $300.00 while providing results with an error of 1.474–14.265%.

There is a paucity of publications about new regional medical campuses. The authors, members of the Association of American Medical Colleges (AAMC) and its Group on Regional Medical Campuses (GRMC), offer a historical perspective about the role of Regional Medical Campuses (RMCs), and provide a roadmap to establishing a new RMC, including logistics, resources, curriculum, student services, faculty, affiliations and networking within the community. A checklist designed to support leadership decision-making is also included. The RMC is an efficient model for increasing opportunities for clinical training, accommodating expansion of graduate medical education, and offering a cost-effective solution to train future physicians.

Chronic pain is perceived by physicians and healthcare systems worldwide as a major challenge, costing US $650 billion per year, which is more than the costs of cancer, cardiovascular diseases, and diabetes [1]. Despite major efforts to find cost-effective solutions, these efforts are heading in the wrong direction. Worldwide, chronic pain-associated knowledge and pain practices are dissociated, and approaches to diagnosis and treatment are mostly based on outdated knowledge and are highly reductionist. Research, medical education, legislation priorities, and directions are influenced by economic dominance, and chronic pain clinical practices, for a significant majority, are going against medical ethics, evidencebased medicine, and cost-effectiveness. In USA, chronic pain patients are misdiagnosed 40-80% of times according to research from John Hopkins Hospital physicians [2]. Over the past 30 years to date, a huge body of research evidence from the perspectives of conventional pain medicine, complementary/integrative pain medicine, and regenerative pain medicine has not been incorporated into chronic pain medical education/training. Therefore, an extensive and comprehensive 30-month clinical fellowship training program was created at McMaster University in Canada (2007–2010) to fill these gaps. Its main outcome is a major shift in pain management goals from extremely costly, unsafe pain relief to the cost-effective treatment or curing of most chronic pain syndromes and their underlying causes.

Abstract3D printing of microfluidic lab-on-a-chip devices enables rapid prototyping of robust and complex structures. In this work, we designed and fabricated a 3D printed lab-on-a-chip device for fiber-based dual beam optical manipulation. The final 3D printed chip offers three key features, such as (1) an optimized fiber channel design for precise alignment of optical fibers, (2) an optically clear window to visualize the trapping region, and (3) a sample channel which facilitates hydrodynamic focusing of samples. A square zig–zag structure incorporated in the sample channel increases the number of particles at the trapping site and focuses the cells and particles during experiments when operating the chip at low Reynolds number. To evaluate the performance of the device for optical manipulation, we implemented on-chip, fiber-based optical trapping of different-sized microscopic particles and performed trap stiffness measurements. In addition, optical stretching of MCF-7 cells was successfully accomplished for the purpose of studying the effects of a cytochalasin metabolite, pyrichalasin H, on cell elasticity. We observed distinct changes in the deformability of single cells treated with pyrichalasin H compared to untreated cells. These results demonstrate that 3D printed microfluidic lab-on-a-chip devices offer a cost-effective and customizable platform for applications in optical manipulation.

To develop a new kind of environment-friendly composite filament for fused deposition modeling (FDM) 3D printing, rice straw powder (RSP)/poly(lactic acid) (PLA) biocomposites were FDM-3D-printed, and the effects of the particle size and pretreatment of RSP on the properties of RSP/PLA biocomposites were investigated. The results indicated that the 120-mesh RSP/PLA biocomposites (named 120#RSP/PLA) showed better performance than RSP/PLA biocomposites prepared with other RSP sizes. Infrared results showed that pretreatment of RSP by different methods was successful, and scanning electron microscopy indicated that composites prepared after pretreatment exhibited good interfacial compatibility due to a preferable binding force between fiber and matrix. When RSP was synergistically pretreated by alkaline and ultrasound, the composite exhibited a high tensile strength, tensile modulus, flexural strength, and flexural modulus of 58.59, 568.68, 90.32, and 3218.12 MPa, respectively, reflecting an increase of 31.19%, 16.48%, 18.75%, and 25.27%, respectively, compared with unmodified 120#RSP/PLA. Pretreatment of RSP also improved the thermal stability and hydrophobic properties, while reducing the water absorption of 120#RSP/PLA. This work is believed to provide highlights of the development of cost-effective biocomposite filaments and improvement of the properties of FDM parts.
