Prospective randomized trial of metal versus resorbable plates in surgical stabilization of rib fractures.

Background: Surgical stabilization of rib fractures has gained popularity as both metal and resorbable plates have been approved for fracture repair. Is there a difference between metal and resorbable plate rib fixation regarding rib fracture alignment, control of pain, and quality-of-life (QOL) scores (Rand SF-36 survey)?

Methods: Eligible patients (pts) included 18 years or older with one or more of the following: flail chest, one or more bicortical displaced fractures (3-10), nondisplaced fractures with failure of medical management. Patients were randomized to either metal or resorbable plate fixation.

Manufacturing biological medicines on demand: Safety and efficacy of granulocyte colony-stimulating factor in a mouse model of total body irradiation.

Protein therapeutics, also known as biologics, are currently manufactured at centralized facilities according to rigorous protocols. The manufacturing process takes months and the delivery of the biological products needs a cold chain. This makes it less responsive to rapid changes in demand.

Point-of-care production of therapeutic proteins of good-manufacturing-practice quality.

Manufacturing technologies for biologics rely on large, centralized, good-manufacturing-practice (GMP) production facilities and on a cumbersome product-distribution network. Here, we report the development of an automated and portable medicines-on-demand device that enables consistent, small-scale GMP manufacturing of therapeutic-grade biologics on a timescale of hours. The device couples the in vitro translation of target proteins from ribosomal DNA, using extracts from reconstituted lyophilized Chinese hamster ovary cells, with the continuous purification of the proteins.
