Pseudomonas aeruginosa is a commonly isolated pathogen in adults with cystic fibrosis (CF). Antimicrobial resistance is an escalating problem due to chronic colonization and frequent antimicrobial exposure. Ceftolozane-tazobactam (C/T) and ceftazidime-avibactam (CZA) exhibit promising activity against antimicrobial resistant organisms, including P. aeruginosa. A retrospective review was conducted comparing the in vitro activities of C/T and CZA against 42 P. aeruginosa isolates from the respiratory tract of 32 adults with CF. The first isolate per patient per year that underwent susceptibility testing for C/T, CZA, and colistin was included. C/T was more susceptible than CZA (60% versus 43%). Thirty-eight (90%) isolates were considered highly drug resistant and demonstrated higher C/T susceptibilities compared to CZA (55% versus 45%). These results suggest using C/T while awaiting susceptibilities when standard antipseudomonal agents cannot be used.
A realistic virtual surgery simulation needs to simulate smoke as electrical cutting causes thermal tissue damage. The vortex particle method of simulating smoke can realistically present the vortex details and motion trajectory of the smoke, but there is high computational cost.
To address this problem, we propose the 3D Vortex Particles in Cube Algorithm (3D-VPICA). 3D-VPICA can realistically show the visual effect of smoke and reduce the computational cost. In addition, in order to enhance the reality of the smoke, we propose the Auxiliary Particles Algorithm (APA) method to deal with the collision problem of smoke.
The 3D-VPICA can calculate the velocity of the vortex particles speedily with the help of cube grids and with the complexity decreasing from O(N
) to O(N)+O(Mlog
M). The APA can ensure that boundary conditions are satisfied when the smoke collides with irregular surfaces. Experimental results show that 3D-VPICA is faster than traditional methods of smoke simulation and that APA is successful in simulating smoke colliding with moving objects with irregular surfaces.
The proposed 3D smoke simulation method was applied to a virtual surgery system using a high frequency electric knife. The cutting and coagulate operations were fluent and the smoke flowed with fidelity.

The HEALing Communities Study (HCS) is testing whether the Communities that Heal (CTH) intervention can decrease opioid overdose deaths through the implementation of evidence-based practices (EBPs) in highly impacted communities. One of the CTH intervention components is a series of communications campaigns to promote the implementation of EBPs, increase demand for naloxone and medications for opioid use disorder (MOUD), and decrease stigma toward people with opioid use disorder and the use of EBPs, especially MOUD. This paper describes the approach to developing and executing these campaigns.
The HCS communication campaigns are developed and implemented through a collaboration between communication experts, research site staff, and community coalitions using a three-stage process. The Prepare phase identifies priority groups to receive campaign messages, develops content for those messages, and identifies a "call to action" that asks people to engage in a specific behavior. In the Plan phase, campaign reough a community-engaged process to effectively address public health crises.
The HEALing Communities Study (HCS) is designed to implement and evaluate the Communities That HEAL (CTH) intervention, a conceptually driven framework to assist communities in selecting and adopting evidence-based practices to reduce opioid overdose deaths. The goal of the HCS is to produce generalizable information for policy makers and community stakeholders seeking to implement CTH or a similar community intervention. To support this objective, one aim of the HCS is a health economics study (HES), the results of which will inform decisions around fiscal feasibility and sustainability relevant to other community settings.
The HES is integrated into the HCS design an unblinded, multisite, parallel arm, cluster randomized, wait list-controlled trial of the CTH intervention implemented in 67 communities in four U.S. states Kentucky, Massachusetts, New York, and Ohio. The objectives of the HES are to estimate the economic costs to communities of implementing and sustaining CTH; estimate broader societal costs associated with CTH; estimate the cost-effectiveness of CTH for overdose deaths avoided; and use simulation modeling to evaluate the short- and long-term health and economic impact of CTH, including future overdose deaths avoided and quality-adjusted life years saved, and to develop a simulation policy tool for communities that seek to implement CTH or a similar community intervention.
The HCS offers an unprecedented opportunity to conduct health economics research on solutions to the opioid crisis and to increase understanding of the impact and value of complex, community-level interventions.

This method can be applied to extrusion of various polymers and deposition on various types of substrates or without use of a substrate at all. The fiber is forced to alternate in its deposit in between two different segments of a collector electrode by a pair of square electric potential functions in anti-phase applied to these two electrode segments. As the fiber oscillation frequency is equal to the potential function frequency, the fiber deposition rate in between these two collector segments can be controlled. If an electrically non-conductive material is placed in between the two segments of the collector electrode, aligned fibers are simply deposited on the surface of this material. The method is used to perform stiffness measurements of the fibers demonstrating Young's modulus of 200.1 MPa with a standard deviation of 30.7 MPa. The stiffness measurement does not require any specialized equipment and requires minimal sample preparation.
