Clinician perspectives on delivering primary and specialty palliative care in community oncology practices.

Purpose: Clinical guidelines recommend early palliative care for patients with advanced lung cancer. In rural and underserved community oncology practices with limited resources, both primary palliative care from an oncologist and specialty palliative care are needed to address patients' palliative care needs. The aim of this study is to describe community oncology clinicians' primary palliative care practices and perspectives on integrating specialty palliative care into routine advanced lung cancer treatment in rural and underserved communities.

Non-invasive treatment of ischemia/reperfusion injury: Effective transmission of therapeutic near-infrared light into the human brain through soft skin-conforming silicone waveguides.

Noninvasive delivery of near-infrared light (IRL) to human tissues has been researched as a treatment for several acute and chronic disease conditions. We recently showed that use of specific IRL wavelengths, which inhibit the mitochondrial enzyme cytochrome oxidase (COX), leads to robust neuroprotection in animal models of focal and global brain ischemia/reperfusion injury. These life-threatening conditions can be caused by an ischemic stroke or cardiac arrest, respectively, two leading causes of death.

Heaterless 300 A lanthanum hexaboride hollow cathode.

Hollow cathodes used in electric propulsion typically have an external heater to raise the thermionic electron emitter to emission temperatures. Heaterless hollow cathodes that are heated by a Paschen discharge have been historically limited to low discharge currents (<5 A) due to arcing and inefficient heating. A new heaterless technology was previously developed for cathodes up to 50 A, utilizing a refractory metal tube to extend the gas feed line partway into the thermionic insert region.

Palliative care use and utilization determinants among patients treated for advanced stage lung cancer care in the community and academic medical setting.

Purpose: Despite clinical guidelines, palliative care is underutilized during advanced stage lung cancer treatment. To inform interventions to increase its use, patient-level barriers and facilitators (i.e.

Development of a 50-A heaterless hollow cathode for electric thrusters.

Hollow cathodes in electric thrusters normally use an external heater to raise the thermionic electron emitter to emission temperatures. These heaters are a potential single-point failure in the thruster and add a separate power supply to the power processing unit. Heaterless hollow cathodes are attractive for their compact size and potential higher reliability but have only been reliably demonstrated to date in small hollow cathodes capable of discharge currents below around 5 A.
