Background And Objective: Accelerometery is used to measure activity behaviours in patients with malignant pleural effusion (MPE). This study aimed to evaluate physical activity and sedentary behaviour profiles of patients with MPE in Hong Kong, and to explore relationships between activity behaviours and quality of life (QoL). We also compared clinician-recorded performance status measures with objective measures of activity levels.

With a sample of 23,218 students from 109 countries and territories, the study reveals that students primarily used ChatGPT for brainstorming, summarizing texts, and finding research articles, with a few using it for professional and creative writing. They found it useful for simplifying complex information and summarizing content, but less reliable for providing information and supporting classroom learning, though some considered its information clearer than that from peers and teachers.

- Biliary-enteric anastomosis (BEA) is a surgical procedure used for issues related to bile ducts and is crucial during liver transplants, with imaging playing a vital role in identifying complications.
- Various imaging techniques like ultrasound, CT, MRI, and nuclear scintigraphy provide different insights, with ultrasound enabling quick assessments and CT offering detailed anatomy.
- Common complications from BEA include bile leaks and strictures, and effective imaging is essential for their early detection and management, ultimately leading to better patient outcomes.
Article Synopsis
- Lithium-sulfur batteries (LSBs) are promising next-gen rechargeable batteries thanks to their high energy density and low-cost sulfur cathodes, but they face challenges with insulation of sulfur particles at low temperatures.
- The study focuses on the generation of liquid sulfur droplets in LSBs and reveals that their formation during the polysulfide oxidation reaction is consistent across various electrolyte/sulfur (E/S) ratios and temperatures.
- Findings suggest that the sulfur oxidation reaction exhibits pseudo-zero-order kinetics and specific reaction constants that vary with E/S ratios, showing that liquid sulfur can be maintained even in extreme conditions like -20 °C.
