Effectiveness and Safety of Dose-Specific DOACs in Patients With Atrial Fibrillation: A Systematic Review and Network Meta-Analysis.

Dose adjustments of direct-acting oral anticoagulants (DOACs) for atrial fibrillation are based on pivotal clinical trials assessing their effectiveness and safety in controlled settings. However, the appropriateness of these dosing strategies in real-world practice is uncertain. The purpose of this study is to compare the effectiveness and safety of dose-specific DOACs with those of warfarin.

The impact of body mass index on mortality according to age in hemodialysis patients: an analysis of the Korean Renal Data System.

The impact of age on the relationship between body mass index (BMI) and all-cause mortality in hemodialysis (HD) patients is not clearly understood. We analyzed the association between BMI and all-cause mortality, stratified by age, in patients undergoing HD using data from the Korean Renal Data System (KORDS). We analyzed 66,129 HD patients from the 2023 KORDS database, with data collected between 2001 and 2022.

Smokers' perceived cancer risks: attributions of the risks and the roles of risks in planning to quit smoking.

This study proposed that smokers' perceived cancer risks differ emotionally and cognitively; the former is based on perceived smoking-related causes, while the latter is based more on perceived non-smoking related causes. It further examined the role of perceived reasons for cancer risk, as well as perceived risks, in planning smoking cessation. The study drew a sample of daily smokers, intermittent smokers and previous smokers (as a reference category) from the Health Information National Trends Survey (HINTS).

Radiation Exposure in Concurrent Abdominoplevic and Chest CT Scans: An Analysis of Overlap and Clinical Impact.

This study investigated the additional radiation exposure, influencing factors, and clinical significance of overlapping Z-axis coverage in abdominopelvic CT scans performed consecutively after same-day chest CT scans. Data from 761 patients were analyzed, with measuring the total and overlapping Z-axis coverage of the portal venous phase in abdominopelvic CT scans. The average overlapping portion was 33.

Strong Enhancement of Light Emission in Core-Shell InGaN/GaN Multi-Quantum-Well Nanowire Light-Emitting Diodes by Incorporating Graphene Quantum Dots.

One-dimensional (1D) vertical nitrides are highly attractive for light-emitting diode (LED) applications because they are useful for overcoming the drawbacks of conventional GaN planar structures. However, the internal quantum efficiency (IQE) of GaN multi-quantum-well (MQW) nanowire (NW) LEDs, typical 1D GaN structures, is still too low to replace standard planar LEDs. Here, we report a phenomenon of light amplification from core-shell InGaN/GaN NW LEDs by incorporating graphene quantum dots (GQDs).
