High-performance solid-state electrochemical thermal switches with earth-abundant cerium oxide.

Thermal switches, which electrically turn heat flow on and off, have attracted attention as thermal management devices. Electrochemical reduction/oxidation switches the thermal conductivity (κ) of active metal oxide films. The performance of the previously proposed electrochemical thermal switches is low; the on/off κ-ratio is mostly less than 5, and the κ-switching width is less than 5 watts per meter kelvin.

US Tobacco 21 Policies and Potential Mortality Reductions by State.

Importance: Research shows that Tobacco 21 (T21) policies with a minimum legal access age for tobacco products of 21 years reduce smoking, yet their impact varies across US states due to differences in smoking behaviors, mortality rates, and policy coverage.

Objective: To quantify potential reductions in smoking-attributable mortality associated with Tobacco 21 policies for each of the 50 states and Washington, DC.

Design, Setting, And Participants: The Cancer Intervention Surveillance and Modeling Network (CISNET) Tobacco Control Policy Model of smoking was used with detailed state-specific data on smoking initiation, smoking cessation and mortality rates as they vary by age, gender, and birth cohort for 50 US states and the District of Columbia.

Application of a minimally invasive full-thickness autologous microcolumn skin harvesting device for donor site tissue collection and augmenting wound healing in a porcine wound model.

Using a 6-week porcine full-thickness excisional wound grafting model, we evaluated the Autologous Regeneration of Tissue (ART®) System, a novel skin harvesting device designed to collect autologous full-thickness autologous microcolumns (FTAM) at 0.5 mm in diameter. The donor skin sites were harvested using the ART® System and compared to split-thickness skin grafts (STSGs).

Interpretable deep learning survival predictions in sporadic Creutzfeldt-Jakob disease.

Background: Sporadic Creutzfeldt-Jakob disease (sCJD) is a rapidly progressive and fatal prion disease with significant public health implications. Survival is heterogenous, posing challenges for prognostication and care planning. We developed a survival model using diagnostic data from comprehensive UK sCJD surveillance.

Diagnostic performance of a point-of-care high-sensitivity cardiac troponin I assay among Chinese patients with chest pain.

Background: A novel handheld point-of-care high-sensitivity cardiac troponin I analyser has recently been introduced to the market. Evaluating its diagnostic performance against laboratory standards is imperative, given the variations in cardiac troponin levels across populations. This study compared the diagnostic performance between the point-of-care high-sensitivity cardiac troponin I assay (Siemens Healthineers Atellica VTLi) and a laboratory high-sensitivity cardiac troponin I assay (Abbott ARCHITECT STAT High Sensitive Troponin-I) performed using blood samples from various populations (overall, male, female, younger and older) of Chinese patients with chest pain.
