Effects of pre-operative education tailored to information-seeking styles on pre-operative anxiety and depression among patients undergoing percutaneous coronary intervention: A randomized controlled trial.

Objective: This study aimed to evaluate the impact of pre-operative education tailored to percutaneous coronary intervention (PCI) patients' information-seeking styles on pre-operative anxiety and depression. Methods: A single-blind randomized control trial was conducted. A total of 114 participants were recruited from the cardiology department in a tertiary hospital in Kunming, Southwest China from April to September 2020 and randomly allocated to the intervention group (n = 57) or control group (n = 57). All patients received oral pre-operative education as well as printed pre-operative education manuals and divided into monitors or blunters by the Chinese Version of the Monitoring Subscale of the Miller Behavioral Style Scale (C-MMBSS). The intervention group received pre-operative education tailored to information-seeking styles, while the control group received routine education. Anxiety and depression were measured at baseline and 1 h before the operation. Satisfaction with pre-operative education and length of stay were assessed at discharge. Results: A total of 104 participants completed the study (52 participants in each group). Pre-operative education tailored to information-seeking styles was beneficial for reducing pre-operative anxiety (P < 0.01), reducing pre-operative depression (P < 0.01), and improving satisfaction with pre-operative education (P < 0.01) compared with routine education. There was no significant difference in length of stay between the intervention and control groups (P = 0.209). Conversely, pre-operative anxiety of patients was increased (P = 0.017) after pre-operative education in the control group. Conclusion: This study confirmed that pre-operative education tailored to information-seeking styles effectively reduces pre-operative anxiety and depression and improves satisfaction with preoperative education.

Cross-cultural adaptation, validity and reliability of the Chinese Version of Miller Behavioral Style Scale.

BACKGROUND: Health education basing on patients' information-seeking styles can improve the effectiveness of health education and patients' health outcomes. The Miller Behavioral Style Scale (MBSS) is widely used to identify individual's information-seeking styles, but the Chinese version is lacking. The study aim was to translate and culturally adapt the MBSS into Chinese version and test the content validity, construct validity and internal consistency reliability of the Chinese version of MBSS (C-MBSS). METHODS: The forward-back-translation procedure was adopted in the translation of the MBSS. Content validity was assessed in a panel of experts. In a sample of 1343 individuals including patients, patients' caregivers, university students, and medical staff, reliability and construct validity were assessed using Cronbach's alpha coefficient and factor analysis. The measurement invariance across samples was tested using multigroup confirmatory factor analysis (MGCFA). Floor and ceiling effects were checked. RESULTS: The C-MBSS achieved conceptual and semantic equivalence with the original scale. The item-level content validity index (I-CVI) of each item ranged from 0.78 to 1, and the averaging scale-level content validity index (S-CVI/ Ave) was 0.95. The exploratory factor analysis resulted in 2-factor assumption for each hypothetical threat-evoking scenario. Confirmatory factor analysis demonstrated a good fit between theoretical model and data, which provided confirmatory evidence for the second-order factor structure of 2-factor solution (Monitoring and Blunting). The Cronbach's alpha coefficients for the Monitoring and Blunting sub-scales of the C-MBSS were 0.75 and 0.62 respectively. MGCFA results supported the measurement invariance for the Monitoring sub-scale of the C-MBSS across samples. No floor or ceiling effects occurred. CONCLUSIONS: This study indicates that the C-MBSS has good content and construct validity. The Monitoring sub-scale of the C-MBSS had acceptable internal consistency reliability while the Blunting sub-scale had unsatisfactory one, which suggest that the Monitoring sub-scale of the C-MBSS can be used to identify individuals' information-seeking styles in Chinese contexts across different populations.

Activation of Autophagy Through the NLRP3/mTOR Pathway: A Potential Mechanism for Alleviation of Pneumonia by QingFei Yin.

QingFei Yin (QFY), a Chinese traditional medicine recipe, is known for its excellent therapeutic pharmacological effects for the treatment of bacterial lung infections, although its molecular mechanism of action remains unknown. Here, QFY chemical composition was determined using a High-Performance Liquid Chromatography-Mass (HPLC-MS/MS)-based method then QFY was evaluated for protective pharmacological effects against pneumonia using two models: a Streptococcus pneumoniae-induced in vivo mouse model and an in vitro pneumolysin (PLY)-induced murine lung alveolar-derived MH-S cell line-based model. Notably, QFY exerted prominent anti-pneumonia effects both in vivo and in vitro. To further explore QFY protective effects, 4D label-free proteomics analysis, pathologic evaluation, and immunohistochemical (IHC) analysis were conducted to identify cellular pathways involved in QFY protection. Notably, our results indicated that NF-κB/NLRP3 and autophagy pathways may contribute to pharmacological effects associated with QFY-based protection. Briefly, QFY triggered autophagy via down-regulation of upstream NLRP3/mTOR signaling pathway events, resulting in the amelioration of inflammatory injury. Collectively, our results revealed molecular mechanisms underlying QFY protection against pneumonia as a foundation for the future development of novel treatments to combat this disease and reduce antibiotic abuse.
