Palliative care management of head and neck cancer patients amongst oral and maxillofacial surgeons: A novel national survey assessing knowledge, decision making, perceived confidence, and training in the UK.

Palliative care strives to improve the quality of life of patients experiencing life-limiting conditions by providing personalised holistic care. Head and neck cancer patients may require palliation at different stages of their disease, thus timely recognition and management is vital when considering supportive care. This study assesses the awareness, perceived confidence, and knowledge of palliative care management of UK-based oral and maxillofacial surgery (OMFS) head and neck surgeons.

Theoretical Coupling of Free-Flowing Ions and Magnetically Insulated Electrons.

Magnetic insulation of electrons prevents losses and can be applied to generating radiation or electron sources for high current and high power applications. Ion emission from the anode may degrade magnetic insulation. We develop equilibrium theory, self-consistently coupling magnetically insulated electron flow with free-flowing injected ions.

Efficacy of Computerized vs. Traditional Cognitive Interventions for the Treatment of Chronic mTBI Symptoms Among Service Members.

Introduction: Military service members (SMs) with mild traumatic brain injury (mTBI or concussion) frequently report cognitive and behavioral difficulties. Currently, military clinical guidelines recommend clinician-run, manualized cognitive rehabilitation (CR) to treat these symptoms; however, it is unclear whether this approach adequately addresses the unique needs of warfighters. Computerized cognitive training (CCT) programs represent an innovative, promising approach to treating cognitive difficulties; however, whether these programs can effectively remediate cognitive impairment in individuals with mTBI remains unclear.

Habitats and Biotopes in the German Baltic Sea.

To maintain or enhance biodiversity and sea floor integrity, mapping benthic habitats is a mandatory requirement in compliance with the Marine Strategy Framework Directive (MSFD). The EU Commission Decision distinguishes between Broad Habitat Types (BHTs) and Other Habitat Types (OHTs). At the regional level, biotopes in the Baltic Sea region are classified according to the HELCOM underwater biotope and habitat classification (HUB).

The transition from field emission to collisional space-charge limited current with nonzero initial velocity.

Multiple electron emission mechanisms often contribute in electron devices, motivating theoretical studies characterizing the transitions between them. Previous studies unified thermionic and field emission, defined by the Richardson-Laue-Dushman (RLD) and Fowler-Nordheim (FN) equations, respectively, with the Child-Langmuir (CL) law for vacuum space-charge limited current (SCLC); another study unified FN and CL with the Mott-Gurney (MG) law for collisional SCLC. However, thermionic emission, which introduces a nonzero injection velocity, may also occur in gas, motivating this analysis to unify RLD, FN, CL, and MG.
