INTRODUCTION: New Zealand has a population of only 5.5 million meaning that for many surgical procedures the country qualifies as a "low-volume center." However, the health system is well developed and required to provide complex surgical procedures that benchmark internationally against comparable countries. This investigation was undertaken to review regional variation and volumes of complex resection and palliative upper gastrointestinal (UGI) surgical procedures within New Zealand...

Oncolytic viruses (OV) are part of a burgeoning field of investigational oncolytic therapy (OT), in which lytic viruses dissolve advanced tumors productively and specifically. One such OT is a Coxsackievirus A21 (CVA21) based OV that is currently under clinical evaluation. A tissue culture infectious dose (TCID50) assay was used for CVA21 potency release and stability testing in early clinical development. The titer measured in this method was an extrapolated value from cytopathic effect (CPE) observed during the serial dilution but doesn't represent direct viral killing of cells...

A major motivation for multiple atmospheric probe measurements at Uranus is the understanding of dynamic processes that create and maintain spatial variation in thermal structure, composition, and horizontal winds. But origin questions-regarding the planet's formation and evolution, and conditions in the protoplanetary disk-are also major science drivers for multiprobe exploration. Spatial variation in thermal structure reveals how the atmosphere transports heat from the interior, and measuring compositional variability in the atmosphere is key to ultimately gaining an understanding of the bulk abundances of several heavy elements...

The airfoil blade is the primary component of a wind turbine, and its aerodynamic properties play a crucial role in determining the energy conversion efficiency of these blades. Many researchers have proposed different airfoil modifications intending to enhance the aerodynamic characteristics and limit the unsteady interaction with the atmospheric boundary layer. This study evaluates the benefits of mounting wedge tails (WTs) on the trailing edge of an airfoil. The aerodynamic characteristics of a 2-D, steady-state NACA 0021 airfoil featuring the wedge tails (WT) and fish wedge tails (FWT) were studied computationally by employing the shear stress transport (SST) k-ω turbulence model...

INTRODUCTION: Little is known about how medical school placements in rural areas impact key stakeholders such as patients, host organisations and the wider rural community. With engagement from rural communities crucial to the success of rural medical training, this case study sought to demonstrate the benefit that rural clinical placements can have on rural general practices (systems) and likely impacts on communities (health outcomes). Specifically, we describe how a series of consecutive short-term student placements in a single rural practice were the drivers of a series of clinical audits and interventions resulting in improved management of chronic disease...

INTRODUCTION: In recent conflicts, the Joint Theater Trauma System (JTTS) led the systematic approach to improve battlefield trauma care, substantially contributing to the unprecedented survival of combat casualties. The Joint Trauma System (JTS) was codified in 2016 to preserve the lessons learned and functions of the JTTS, including the Department of Defense Trauma Registry. Concurrently, Combatant Commands (CCMD) were directed to establish CCMD Trauma Systems (CTS) "modeled after the JTTS" and to maintain a baseline of core functions intended to rapidly scale as needed...

Improving the tolerance of flexible polymers to extreme temperatures and electrical fields is critical to the development of advanced electrical and electronic systems. Suppressing carrier movement at high temperatures is one of the key methods to improve the high-temperature charging and discharging efficiency. In this work, a molecular semiconductor (ITIC) with high electron affinity energy is blended into the promising polymer polyetherimide (PEI). This molecular semiconductor will introduce traps in the dielectric that can trap carriers, thus achieving the effect of inhibiting carrier movement...

The purpose of this manuscript was to consider how mainstream health organisations can develop structures, processes, and functions to address inequity, using the New Zealand Cancer Control Agency (Te Aho o Te Kahu) as an example. In New Zealand (Aotearoa), as in other countries, inequities in cancer incidence and outcomes exist between population groups, including for indigenous populations. Despite much discussion regarding the need to address racial inequities, often the proposed solutions are at operational or programmatic levels, and disadvantaged communities are unable to have much of a say in the system design and service delivery of these solutions...

BACKGROUND: Between conflicts, many of the combat casualty care lessons learned are lost as the nation shifts priorities and providers leave the military. Solutions are needed to bridge the knowledge gap created by interwar periods. One of the foremost solutions is partnerships between civilian trauma centers and the military health system. Over the past two decades, a myriad of military-civilian partnerships (MCPs), which vary in their composition, duration, and focus, was created. The objective of this report is to describe the initial attempt of the Department of Defense to catalog existing MCPs to inform both civilian and military stakeholders...
