Bacterial infections seriously threaten human health. Although antibiotics can significantly treat infectious diseases, antibiotics abuse has brought a series of serious problems, such as multidrug-resistant bacteria, adverse effects, and so on. Therefore, it is indispensable to develop alternative therapies with superior efficacy and minor toxicity to enhance the anti-infective outcome, overcome drug resistance and reduce adverse effects. The phase change material (PCM) is a substance that changes its physical properties with elevated temperatures. Nanoparticles based on PCM have been widely used in biomedical research due to their excellent biocompatibility, sustained release, and outstanding targeting properties. In this manuscript, the applications of PCM-based nanoparticles in the treatment of bacterial infections were summarized. Firstly, the composition and biotoxicity of PCM nanocarriers were described. Secondly, various antibacterial strategies based on PCM nanoparticles for combination therapy were highlighted. Finally, the prospects for antibacterial therapy of PCM nanomaterials were summarized.

Magnetocaloric high-entropy alloys (HEAs) have recently garnered significant interest owing to their potential applications in magnetic refrigeration, offering a wide working temperature range and large refrigerant capacity. In this study, we thoroughly investigated the structural, magnetic, and magnetocaloric properties of equiatomic GdDyHoErTm HEAs. The as-cast alloy exhibits a single hexagonal phase, a randomly distributed grain orientation, and complex magnetism.

Objective: To develop and assess the psychometrics of the Chronic Headache Self-Efficacy Scale (CHASE).
Background: Existing scales assess self-efficacy in coping strategies and management of symptoms and triggers but do not measure other important self-efficacy domains, such as performing daily activities and socializing in patients with chronic daily headache (CDH).
Methods: The study had two phases: (i) Development of the 14-item CHASE, with items derived from patients with CDH and a multidisciplinary healthcare team; (ii) longitudinal observational study for psychometric evaluation.
The Use of Dietary Supplements for the Management of Adverse Effects of Treatment in Children and Adolescents with Leukemia: A Scoping Review.

Acute lymphoblastic leukemia is the most prevalent form of leukemia in children and adolescents. Despite high survival rates due to advanced treatments, these therapies often result in significant treatment-related adverse effects. This scoping review explores dietary supplementation strategies for managing these adverse effects in pediatric leukemia patients.

Background: Sleep is substantial issue for hospital inpatients and can negatively affect healing and recovery. There is a good evidence-base for interventions which can improve sleep, however currently they are not being implemented into NHS practice. To address the evidence-practice gap, we have conducted early-phase development for an inpatient sleep intervention (ASLEEP); a multi-level intervention to improve inpatient sleep in UK hospital wards.

Dexmedetomidine (DexM), a highly selective α-adrenoceptor agonist, significantly reduces postoperative adverse effects, including sleep and circadian rhythm disruptions. Vasoactive intestinal peptide neurons in the suprachiasmatic nucleus (SCN) regulate the synchronization of circadian rhythms with the external environment in mammals. We investigate the effects of DexM on sleep and circadian rhythms, as well as the underlying mechanisms.
