Novice nurses' transition shock and professional identity: The chain mediating roles of self-efficacy and resilience.

AIMS AND OBJECTIVES: The aim of this study was to explore the association between transition shocks and professional identity and the mediating roles of self-efficacy and resilience among Chinese novice nurses. BACKGROUND: Novice nurses experience transition shock when they start their careers, which might lead to decreased professional identity and ultimately turnover. By contrast, self-efficacy and resilience are excellent psychological resources that may be associated with higher professional identity. It is unclear how transition shock affects professional identity by influencing these two internal resources. DESIGN: A cross-sectional survey. METHODS: The STROBE guidelines were followed to report this study. Convenience sampling was used to recruit participants, and 252 novice nurses completed the Transition Shock of Novice Nurses Scale, the Professional Identity Assessment Scale, the General Self-Efficacy Scale and the Connor-Davidson Resilience Scale between April 2022 and May 2022. Influencing factors were primarily identified using independent-sample t-tests and a one-way ANOVA. Structural equation modelling was used to detect the mediating effects of self-efficacy and resilience. RESULTS: Differences in novice nurses' levels of professional identity were found across age groups, hospitals and departments. Transition shock was negatively related to professional identity. Self-efficacy and resilience mediated the complete chain relationship between transition shock and professional identity. CONCLUSION: To our knowledge, this study is the first to explore the mediating effect of self-efficacy and resilience on transition shock and professional identity. Higher transition shock may lead to lower professional identity by reducing self-efficacy and resilience. RELEVANCE TO CLINICAL PRACTICE: Nursing managers ought to emphasise the significant role of psychological resources in the work adaptation process of novice nurses. It may be more effective to improve professional identity and maintain the stability of the health care system. PATIENT OR PUBLIC CONTRIBUTION: Nursing administrators working at seven preselected hospitals actively assisted us in the process of collecting self-report questionnaires from novice nurses, such as by booking appointments and providing access for questionnaire administration. In addition, the participants were actively involved in the data collection process.

Experience in developing innovative practical ability for Master of Nursing Specialist degree program in China: A qualitative descriptive study of postgraduates.

BACKGROUND: Nursing talent training should be adjusted in accordance with policies and regulations, the priority areas of health care, the development of nursing disciplines, and changes in nurses' roles. Experience from nursing education stakeholders indicates that postgraduate education faces numerous challenges. Thus, it is necessary to discuss postgraduates' experience in cultivating innovative practical ability. OBJECTIVES: To analyze the experiences of nursing specialist postgraduates in cultivating innovative practical ability to provide a reference for further improvement of the Master of Nursing Specialist program. DESIGN: A qualitative study. SETTING: A university and its three affiliated tertiary hospitals in H city, China. PARTICIPANTS AND METHODS: Individual, semi-structured interviews were conducted face-to-face with 12 postgraduates currently in clinical practice and six postgraduate nurses within two years of graduation between April and June 2022. All interviews were audio-recorded and transcribed verbatim, and the data were analyzed using the Colaizzi method. RESULTS: Three key themes emerged: (1) the cognition of innovative practical ability; (2) the experience of cultivating innovative practical ability at school; and (3) the experience of cultivating innovative practical ability in the hospital. CONCLUSIONS: With a full understanding of the training experience of postgraduates' innovative practical ability, policymakers and training units can clarify the shortcomings of the training model, make targeted improvements, and work together to build a more scientific and complete MNS training model. Our findings have the potential to inform faculty structure, catalyze curriculum reform, optimize clinical practice to facilitate the development of Master of Nursing Specialist programs, improve the quality of care, and promote patient recovery.

Antagonistic Effect and In Vitro Activity of Dauricine on Glucagon Receptor.

Abnormal increases in glucagon (GCG) are the primary cause of type II diabetes mellitus. When GCG interacts with a glucagon receptor (GCGR), GCG can increase the blood glucose level. In this paper, a compound that could interfere with the binding of GCG and GCGR to inhibit the increase of blood glucose was investigated. First, molecular docking was used to conduct preliminary screening of compounds whose active components could combine with GCGR by AutoDock Vina. The binding of the receptor-ligand complex was analyzed by PyMOL. Results showed that dauricine could tightly bind to the receptor pocket. Second, the plasmid pcDNA3.1(+)-GCGR containing the target gene was transfected into HEK293 cells for expression, which was the cell model established to screen GCGR antagonist. Dauricine, the lead compound of glucagon receptor antagonist (GRA), was screened using the GRA screening model in vitro. Finally, using [Des-His1, Glu9]-Glucagon amide as the positive control, flow cytometry was used to express the antagonistic effect of the compound. Consequently, dauricine can antagonize the GCGR.

Novel topological index for research on structure-property relationships of complex organic compounds.

Based on bonding parameters such as Yang's Electronegative Force Gauge Y(i), electronic number of valence layer Z(i), number of combined hydrogen atoms h(i), number of bonding electron b(i), and quantum number such as the highest main quantum number of valence layer n(i), a novel atomic valence delta(i) (Y) is defined and a novel topological index (1)chi(Y) is derived from the atomic valence. The atomic valence is defined as delta(i) (Y) = (Z(i) - h(i))b(i)/n(i) (2)Y(i), while the topological index is expressed as (1)chi(Y) summation operator (i,j=1) (m) (delta(i) (Y)delta(j) (Y))(-1/2). Subsequently, the index (1)chi(Y) is utilized to study the structure-property relationships of complex organic compounds. The results of correlativity showed that the index is highly and extensively correlated with such properties as solubility of phenyl chlorides, gas chromatographic retention index of alkoxyl silanes, and toxicity of heterocyclic nitrogen-containing compounds. Moreover, predicted values are quite consistent with experimental ones when the index is employed to predict the partition coefficient (log P) of fatty alcohols, phenyl chlorides, and barbitals. Compared to the topological indices reported in the literature, the universality and reliability of (1)chi(Y) to the properties of complex organic compounds have been distinctively improved, and its calculating process is simple and convenient.
