In addition to inducing xylem embolism, freeze-thaw events can cause frost fatigue phenomena. Freezing temperature, freezing times, number of freeze-thaw cycles and frost drought can affect the level of freeze-thaw-induced embolism, but it is unknown whether there is an effect on frost fatigue. We assessed whether these frost-related factors changed frost fatigue in the three diffuse-porous species by simulating freeze-thaw treatments under different conditions. We also proposed a new metric, embolism area, in place of embolism resistance, to more accurately quantify the shift of the vulnerability curve after experiencing freeze-thaw-induced embolism and refilling. Frost fatigue caused vulnerability curves of all species to change from S-shaped to double S-shaped or even R-shaped curves. When exposed to a freeze-thaw event, Acer truncatum showed strong resistance to frost fatigue; in contrast, Populus (I-101 × 84 K) and Liriodendron chinense were more vulnerable. Changing freezing temperature and times did not impact the response to frost fatigue in the three species, but a greater number of freeze-thaw cycles and more severe frost drought significantly exacerbated their fatigue degree. Considering that frost fatigue may be a widespread phenomenon among temperate diffuse-porous species, more work is needed in the future to reveal the mechanisms of frost fatigue.

Long COVID is highly prevalent and debilitating, with key symptoms including fatigue, breathlessness, and brain fog. Pacing is an approach to energy conservation used to help people with chronic conditions like ME/CFS manage the impact of their condition, and could be a useful strategy for people with Long COVID. The aim of this study was to explore the views and experiences of non-hospitalised adults with Long COVID of pacing as an intervention.

Background: Circadian preference for eveningness has been linked to a higher risk of asthma and allergies, but its association with health-related quality of life (HRQL) in asthma has not been studied yet.
Objective: We aimed to investigate the associations between individual circadian preference and HRQL in asthma.
Methods: Among 691 adult asthma patients from Canada, India, New Zealand, and the United Kingdom, a digital questionnaire was administered to capture demographic information, social and psychologic attributes, comorbidities, and medication adherence.

Background: Allogeneic hematopoietic stem cell transplantation (allo-SCT) is an effective treatment for various hematologic cancers, though it often results in severe side effects and psychological distress, which can negatively impact health outcomes. Integrative therapies like mindfulness-based stress reduction (MBSR), mindfulness meditation (MM), and music therapy (MT) yield promising results in enhancing both psychosocial outcomes (eg, reducing anxiety and depression) and physiological adaptation (eg, decreasing inflammation) in cancer patients.
Objective: We developed and refined, using focus groups and environmental and field testing, an eHealth-delivered mindfulness-based music therapy (eMBMT) intervention aimed at improving health-related quality of life, symptom burden (ie, pain, fatigue, and sleep), disease activity (ie, chronic graft-versus-host disease, cytomegalovirus activation, and infections) and psychosocial (ie, depression, anxiety, and cancer-specific distress) and physiological adaptation (ie, inflammation and immune reconstitution) tailored to adults receiving allo-SCT.

With the rapid development of flexible electronics technology, high-performance flexible sensors have shown great potential in wearable devices and human-computer interaction fields. In this study, a hydrogel (PMAGZ) reinforced by gelatin and Zn was prepared using a one-pot method, which formed a triple-bonded cross-linked network structure through covalent, hydrogen, and ligand bonds to exhibit excellent mechanical properties and sensing characteristics, and can be applied to multimodal sensors and handwriting recognition. The introduction of gelatin and Zn strengthens the cross-linked structure inside the hydrogel, which can effectively improve the tensile strength, strain, and toughness of the hydrogel.

Background: Menopause can be seen as a complex phenomenon influenced by an individual's cultural norms, belief systems, and lifestyle choices. In conservative societies such as Saudi Arabia, some women silently struggle with menopause due to cultural taboos and social stigma, making their experiences invisible and lowering their quality of life. The aim of this study was to explore in-depth the knowledge, attitudes, and experiences of middle-aged Saudi women with menopause.
