Abstract

Three-dimensional (3D) printing and additive manufacturing holds potential for highly personalized medicine, and its introduction into clinical medicine will have many implications for patient care. This paper demonstrates the first application of 3D printing as a method for the potential sustained delivery of antibiotic and chemotherapeutic drugs from constructs for patient treatment. Our design is focused on the on-demand production of anti-infective and chemotherapeutic filaments that can be used to create discs, beads, catheters, or any medical construct using a 3D printing system. The design parameters for this project were to create a system that could be modularly loaded with bioactive agents. All 3D-printed constructs were loaded with either gentamicin or methotrexate and were optimized for efficient and extended antibacterial and cancer growth-inhibiting cytostatic activity. Preliminary results demonstrate that combining gentamicin and methotrexate with polylactic acid forms a composite possessing a superior combination of strength, versatility, and enhanced drug delivery. Antibacterial effects and a reduction in proliferation of osteosarcoma cells were observed with all constructs, attesting to the technical and clinical viability of our composites. In this study, 3D constructs were loaded with gentamicin and methotrexate, but the method can be extended to many other drugs. This method could permit clinicians to provide customized and tailored treatment that allows patient-specific treatment of disease and has significant potential for use as a tunable drug delivery system with sustained-release capacity for an array of biomedical applications.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 23 November 2016.
All research outputs
#14,388,554
of 25,374,647 outputs
Outputs from International Journal of Nanomedicine
#1,492
of 4,123 outputs
Outputs of similar age
#174,854
of 359,528 outputs
Outputs of similar age from International Journal of Nanomedicine
#40
of 73 outputs
Altmetric has tracked 25,374,647 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,123 research outputs from this source. They receive a mean Attention Score of 4.7. This one has gotten more attention than average, scoring higher than 63% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 359,528 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 50% of its contemporaries.
We're also able to compare this research output to 73 others from the same source and published within six weeks on either side of this one. This one is in the 45th percentile – i.e., 45% of its contemporaries scored the same or lower than it.
