The accuracy and noninvasive nature of the doubly labeled water (DLW) method makes it ideal for the study of human energy metabolism in free-living conditions. However, the DLW method is not always practical in many developing and Asian countries because of the high costs of isotopes and equipment for isotope analysis as well as the expertise required for analysis. This review provides information about the theoretical background and practical aspects of the DLW method, including optimal dose, basic protocols of two- and multiple-point approaches, experimental procedures, and isotopic analysis. We also introduce applications of DLW data, such as determining the equations of estimated energy requirement and validation studies of energy intake.

Intelligent stimuli-responsive actuators that can convert environmental energies into mechanical works have garnered significant research interests. Among different actuation principles, Marangoni effect is distinguished due to simplicity, high efficiency, remote manipulation, and water environment adaptability. Nevertheless, both chemical and physical Marangoni actuators face their own challenges with respect to limited chemical loading, precise light illumination, and relatively poor motion controllability.

Background: Approximately half of the patients with acute ischemic stroke who receive intravenous thrombolysis (IVT) do not achieve an excellent outcome. Remote ischemic conditioning (RIC) as a promising neuroprotective treatment may improve clinical outcomes in this population. This study aimed to assess the efficacy and safety of RIC in patients with IVT.

Background: Although water intake (WI) is commonly estimated through self-reporting, its inaccuracy is reported. Water turnover (rHO)-derived WI is the reference method; however, it is costly. The study aimed to validate alternative methods for determining WI in a group of athletes.

Objectives: To highlight the often overlooked role of user interface (UI) design in mitigating bias in artificial intelligence (AI)-based clinical decision support (CDS).
Materials And Methods: This perspective paper discusses the interdependency between AI-based algorithm development and UI design and proposes strategies for increasing the safety and efficacy of CDS.
Results: The role of design in biasing user behavior is well documented in behavioral economics and other disciplines.
