001). Of 7,608 patients undergoing revision between 91 and 365days, 1,110 (15%) were revised at a different hospital. Changing hospitals was associated with having primary TKA at a lower volume hospital (26% for low, 14% medium, 10% high, and 9% very high; P<0.001). Changing hospitals was not associated with sex or age.

Patients frequently undergo revision for PJI at a different hospital, even within 90days of TKA. Further research is needed to understand these implications of this care pathway shift.

The inhibition on CYP2C9 enzyme was thought to be the mechanism, but further studies are warranted. Thus, a mechanistic PBPK/PD model for warfarin enantiomers was developed to predict DDI potential with sorafenib, aiming at providing reference for the rational use of both drugs. PBPK models of warfarin enantiomers were constructed by Simcyp software. A mechanistic PK/PD model was built in NONMEM software. PBPK model of sorafenib was fitted via a top-down method. The final PBPK/PD model of warfarin enantiomers was verified and validated by different dosing regimens, ethnicities and genetic polymorphisms, and used to perform DDI simulations between warfarin racemate and sorafenib among general populations and sub-populations with various CYP2C9 and VKORC1 genotypes. Results suggested low DDI risk between warfarin and sorafenib for general populations. Potentially serious consequence was seen for those carrying both CYP2C9 ∗2 and ∗3 and VKORC1 A/A genotypes. SGI-110 This PBPK/PD modeling approach for warfarin enantiomers enabled DDI evaluation with sorafenib. Close monitoring and warfarin dosage adjustment were recommended for patients carrying mutant genotypes. The novel model could be applied to investigate other drugs that may interact with warfarin.Asthma is one of the most prevalent diseases worldwide, and β2-adrenergic receptor (β2AR) agonists have been reported to be highly effective bronchodilators against this disease. In this study, we successfully constructed a novel CHO-β2AR affinity chromatography (CHO-β2AR/AC), which was evaluated by infrared spectroscopic and scanning electron microscope (SEM) analysis. In addition, CHO-β2AR/AC model exhibited good selectivity and reliability with the relative standard deviation smaller than 5.6% after 30 days. Furthermore, an interaction force analysis model was developed based on CHO-β2AR/AC. The results showed that the interaction force analysis model (Φ•E•pKa) exhibited a strong correlation with equilibrium dissociation constant (KD) (r2=0.9284, p=0.002) and a good correlation with logarithm of half-maximum effective concentration (pEC50) values (r2=0.7135, p=0.034). In addition, a pool of clinically approved drugs was screened by this CHO-β2AR/AC model. Codeine wasfound to bind to and activate β2AR with KD value of 4.10 × 10-7 M, leading to increased cyclic adenosine monophosphate (cAMP) production with EC50 of 6.49 × 10-7 M and reduction of intracellular Ca2+ concentration, which in turn relaxes bronchial contraction with EC50 of 2.62 × 10-6 M. Furthermore, the KD value and pEC50 of codeine were within the 95% prediction range of the interaction force analysis model. The results indicate that the CHO-β2AR/AC with interaction force analysis model constructed in this study can be used to effectively and rapidly screen active compounds targeting β2AR.Implementation of viscoelasticity-based particle migration techniques has attracted significant interest thanks to its simplicity to achieve particle separation and enrichment at high sensitivity and accuracy for the last decade. Many methods have previously been developed for particle focusing and separation, but they all require long fluidic channels to enable the desired elastic force on particles. Here, a cascade contraction-expansion microfluidic system with a much shorter channel length is presented. Experimental results show that this system achieved continuous, sheathless particle separation in a viscoelastic fluid, and Enterococcus faecalis was successfully separated from red blood cells (RBCs). Thanks to its small size, the system provides extra advantage for its integration into small chips.With two thirds of the global population living in areas affected by water scarcity, wastewater reuse is actively being implemented or explored by many nations. There is a need to better understand the efficacy of recycled water treatment plants (RWTPs) for removal of human opportunistic pathogens and antimicrobial resistant microorganisms. Here, we used a suite of probe-based multiplex and SYBR green real-time PCR assays to monitor enteric opportunistic pathogens (EOPs; Acinetobacter baumannii, Arcobacter butzlieri, Escherichia coli, Enterococcus faecalis, Klebsiella pneumoniae, Legionella spp., Listeria monocytogenes, Pseudomonas aeruginosa, Salmonella Enteritidis, Streptococcus spp.) and antimicrobial resistance genes (ARGs; qnrS, blaSHV, blaTEM, blaGES, blaKPC, blaIMI, blaSME, blaNDM, blaVIM, blaIMP, blaOXA-48-like, mcr-1 and mcr-3) of key concern from an antimicrobial resistance (AMR), waterborne and foodborne disease perspective. The class 1 integron-integrase gene (intl1) was quantified as a proxy for multi-drug resistance. EOPs, intl1 and ARGs absolute abundance (DNA and RNA) and metabolic activity (RNA) was assessed through three RWTPs with differing treatment trains. Our results indicate that RWTPs produced high quality recycled water for non-potable reuse by removing >95% of EOPs and ARGs, however, subpopulations of EOPs and ARGs survived disinfection and demonstrated potential to become actively growing members of the recycled water and distribution system microbiomes. The persistence of functional intl1 suggests that significant genetic recombination capacity remains in the recycled water, along with the likely presence of multi-drug resistant bacteria. Results provide new insights into the persistence and growth of EOPs, and prevalence and removal of ARGs in recycled water systems. These data will contribute towards the emerging evidence base of AMR risks in recycled water to inform quantitative risk-based policy development regarding water recycling schemes.
