Aims: Nurses' hand temperature may affect patient comfort but has not been investigated. This study aimed to determine female hospital nurses' hand skin temperature and clarify the effects of measurement site, time, nursing procedures, and environment.
Design: An observational study.
Methods: The middle finger, thenar eminence, hypothenar eminence, and medial forearm skin temperature of 29 female hospital nurses was measured at four time points during a day shift and before and after nursing procedures (hand disinfection, hand washing, taking vital signs, hygiene care, and positioning).
Results: Mean hand skin temperature was in the range of 29-32°C with interpersonal variations. Mean skin temperature at the medial forearm was 31.94-32.35°C (SD 0.87-1.52°C) and at the middle finger, 29.73-31.07°C (SD > 3°C). Time-dependent skin temperature fluctuations were confirmed on the middle finger (p = .022), and thenar (p = .005) and hypothenar eminence (p = .001). There were weak correlations between skin temperature and environmental factors, including ambient temperature (ρ = .194-.266), humidity (ρ = -.309 to -.319), and hospital room wind speed (ρ = .253-.314). The skin temperature dropped significantly after hand disinfection and handwashing at all measurement sites (middle finger: -1.30 and -3.56°C, respectively; thenar eminence: -1.19 and -3.32°C; hypothenar eminence: -0.80 and -3.39°C; medial forearm: -0.21 and -1.60°C).
Conclusion: These findings may raise nurses' awareness of their skin temperature. Moreover, our study highlights the need to develop countermeasures to ensure optimal nurses' skin temperature and patient comfort.

Skin-like sensors capable of detecting multiple stimuli simultaneously have great potential in cutting-edge human-machine interaction. However, realizing multimodal tactile recognition beyond human tactile perception still faces significant challenges. Here, an extreme environments-adaptive multimodal triboelectric sensor was developed, capable of detecting pressure/temperatures beyond the range of human perception.

Introduction And Importance: Calcific tendinitis occurring in the popliteal tendon is extremely rare and has rarely been reported in the past. This case describes a patient who underwent arthroscopic surgery to remove the calcification of the popliteal tendon and achieved satisfactory results after surgery, providing valuable evidence for the feasibility of arthroscopic treatment of calcific tendinitis of the popliteal tendon.
Case Presentation: The patient was a 55-year-old female who was admitted to the hospital due to right knee pain and limited mobility.

Background: Cognitive changes affecting performance are subtle in early stages of Alzheimer's Disease (AD) and may emerge only with more complex tasks. Driving is a highly challenging instrumental activity of daily living, requiring higher order integration of cognitive skills. For example, driving on freeway entrance ramps requires heightened cognitive engagement such as rapid responses to fast-emerging traffic and sudden speed changes, combining sensory processing and manipulative actions.

As one of the core parts of the Internet-of-things (IOTs), multimodal sensors have exhibited great advantages in fields such as human-machine interaction, electronic skin, and environmental monitoring. However, current multimodal sensors substantially introduce a bloated equipment architecture and a complicated decoupling mechanism. In this work we propose a multimodal fusion sensing platform based on a power-dependent piecewise linear decoupling mechanism, allowing four parameters to be perceived and decoded from the passive wireless single component, which greatly broadens the configurable freedom of a sensor in the IOT.

Ionic skin can mimic human skin to sense both temperature and pressure simultaneously. However, a significant challenge remains in creating precise ionic skins resistant to external stimuli interference when subjected to pressure. In this study, we present an innovative approach to address this challenge by introducing a highly anisotropic nanofluidic ionic skin (ANIS) composed of carboxylated cellulose nanofibril (CNF)-reinforced poly(vinyl alcohol) (PVA) nanofibrillar network achieved through a straightforward one-step hot drawing method.
