This case report describes the case of a female infant hospitalized for severe pneumonia. During the treatment process, various antibiotics are used to treat and prevent further infection. The child had a weak physical condition, combined with neuroblastoma, paraneoplastic syndrome, and low immune function, leading to Tsukamurella tyrosinosolvens infection. The treatment was eventually abandoned owing to poor prognosis. This study aims to through the medium, dyeing, electron microscope observation, 16s rRNA and high-throughput sequencing investigated the morphological characteristics, staining properties, electron microscope morphology, antibiotic resistance, and genomic characteristics of Tsukamurella tyrosinosolvens. The aim of the study is to provide data reference for clinical laboratory staff in bacteria identification research, and to provide relevant help for clinicians in diagnosis and treatment.

Aims: To examine the factors influencing compassion fatigue and compassion satisfaction in obstetrics and gynaecology nurses and to explore the combined results of multiple factors. Design: An online cross‐sectional study was conducted. Review Methods: Data were collected from 311 nurses using a convenience sampling method from January to February 2022. Stepwise multiple linear regression analysis and mediation tests were performed. Results: Compassion fatigue in obstetrics and gynaecology nurses was in the moderate to high levels. Physical status, number of children, emotional labour, lack of professional efficacy, emotional exhaustion and the none‐only‐child can influence compassion fatigue; lack of professional efficacy, cynicism, social support, work experience, employment status and night shift were predictive of compassion satisfaction. Social support partially mediated between lack of professional efficacy and compassion fatigue/compassion satisfaction; emotional labour moderated in the mediated analysis model. Conclusion: Moderate to high levels of compassion fatigue was present in 75.88% of obstetrics and gynaecology nurses. Some factors affect compassion fatigue and compassion satisfaction. Thus, nursing managers should consider factors and construct a monitoring system to reduce compassion fatigue and improve compassion satisfaction. Implications for the Profession: The results will provide a theoretical basis for improving job satisfaction and the quality of care in obstetrics and gynaecology nurses. And this may raise concerns about the occupational health of obstetrics and gynaecology nurses in China. Reporting Method: The study was reported according to the STROBE. Patient or Public Contribution: The nurses spent time filling out the questionnaires during the data collection phase and answered the questions sincerely. What does this article contribute to the wider global clinical community?: Obstetrics and gynaecology nurses with 4–16 years of experience are prone to experience compassion fatigue.The effect of lack of professional efficacy on compassion fatigue and compassion satisfaction can be improved by social support. Relevance to Clinical Practice: Reducing nurse compassion fatigue and improving compassion satisfaction are important for providing quality nursing care to obstetrics and gynaecology patients. In addition, clarifying the influencing factors of compassion fatigue and compassion satisfaction can improve nurses' work efficiency and job satisfaction, and provide theoretical guidance for managers to implement interventions.

• A novel Ni 43 Mn 32 In 25 Heusler alloy film is deposited on Ni foam by PLD. • The activated NiMnIn/NF possesses overpotentials of 133.4 mV at a current density of –10 mA cm–2 for HER. • Electromagnet is used to realize the electrochemical measurement under in situ magnetic field. • Magnetic field promotes catalytic activity of NiMnIn/NF for HER. [Display omitted] Much effort has been devoted to developing novel electrodes of lower cost and higher efficiency to electrolyze water in scalable applications, which is mainly focused on 3d transition metals or oxides. In this work, Ni 43 Mn 32 In 25 (NiMnIn) Heusler alloy films with highly efficient hydrogen evolution reaction (HER) activity were deposited on porous Ni foam (NF) by pulsed laser deposition. With the synergetic contribution of constituent elements, the as-prepared NiMnIn films exhibited excellent performance with a low overpotential of 189.4 mV in the initial state and 133.4 mV after activation (at a current density of −10 mA cm−2) for HER in alkaline medium. Magnetic measurements have confirmed the ferromagnetic nature of NiMnIn films at room temperature, and the HER activity can be significantly improved by applying a magnetic field. The current density of NiMnIn/NF could be increased by 10% and 7% respectively, at a constant overpotential of 275 mV by applying a magnetic field of 8 kOe perpendicular and parallel to NF. This work suggests that Heusler alloys with various 3d transition metal constituents can be a potential efficient HER active electrode in water splitting, which has the magnetic field sensitivity for applications in magnetoelectrochemistry.
