    BackgroundA proper evaluation on the intention of using nutrition label in patients with coronary heart disease (CHD) is crucial to design and formulate of behavior-based interventions. A valid and reliable instrument based on theoretical basis is needed to measure individual intention toward nutrition label use and identify underlying socio-cognitive factors.ObjectTo develop and test validity and reliability of the theoretically based nutrition label use (NLU) scale and to promote the use of nutrition labels in CHD patients.MethodsA questionnaire was developed based on the theory of planned behavior (TPB), empirical literatures, expert review and pilot tested. A total of 460 CHD patients in a hospital in Changsha were investigated using this questionnaire from April 2021 to August 2021. The items and dimensions in the scale were explored and confirmed using item-analysis, content validity, exploratory factor analytical (EFA), confirmatory factor analytical (CFA), internal consistency and split-half reliability tests.ResultsA total of 33 items with 4 structural factors were identified, including 10 items of attitude, 6 items of subjective norm, 12 items of perceived behavior control, and 5 items of intention. The total variance explained by the EFA model was 68.563%. The model was further tested with CFA. The measurement model fitted the data well (Ratio of chi-square minimum and degree of freedom (CMIN/DF) =1.743, goodness of fit index (GFI) =0.814, incremental fit index (IFI) =0.946, Tuker-Lewis index (TLI) =0.940, the comparative fit index (CFI) =0.945, the root mean square error of approximation (RMSEA) =0.057). The content validation index (CVI) of the scale was 0.82, and the CVI of the items ranged from 0.8 to 1.00. The reliability of the scale was 0.976 (p ConclusionThe newly developed Nutrition Label Use Scale can serve as a valid and reliable tool to evaluate the nutrition label use of CHD patients.</p

    PTSA-catalyzed one-pot synthesis of quinoxalines using DMSO as the oxidant

    <p>An efficient p-toluene sulfonic acid–catalyzed, one-pot, two-step oxidative system for cyclization of o-diaminobenzene with 1,2-diaryl-2-hydroxyethanone to quinoxalines was described. A nontoxic, readily available oxidant, dimethylsulfoxide (DMSO), was applied in this process. A broad range of substrates was applied to this method, and target compounds were obtained with good yields.</p

    Data_Sheet_1_Altruism in nursing from 2012 to 2022: A scoping review.doc

    Full text link
    BackgroundBeing a nurse with non-altruistic orientation exists and altruism decline is being challenged as never before, which would be a disaster for medicine if left unnoticed.PurposeTo describe the meaning of altruism and altruistic behaviors in nursing, and to discuss dilemmas we face today.MethodCochrane, PROSPERO, PubMed, Web of Science, CINAHL, Scopus, Embase, ProQuest, and CNKI were searched for original research published in English or Chinese from 2012 to February 2022.ResultsBy screening 13 studies came from 12 different countries described altruism and altruistic behavior together were included in. Altruism has been described as value, vocation, or professionalism in nursing which can reflect nurses' compassion, level of expertise, and quality of care. Altruistic nursing care, body donation, financial endowment, volunteering, sharing, benefiting patients maximum, and helping colleagues represented most of the altruistic behaviors in nursing. There is a vacant that not any assessment tool designed for measuring altruism in nurse groups. Interventions from curriculums in class and support of organizations with psychological methods could be helpful to improve the nurses' level of altruism.ConclusionAltruism and altruistic behaviors in the past decades were described. A new concept of altruism in nursing was proposed based on the original meaning and the current changes, and interventions for promoting altruism and some of the dilemmas faced today were synthesized.</p

    Cascade One-Pot Method To Synthesize Isoquinolin-1(2<i>H</i>)‑ones with α‑Bromo Ketones and Benzamides via Pd-catalyzed C–H Activation

    Full text link
    A cross-coupling strategy of palladium-catalyzed <i>ortho</i>-C–H bond activation and intramolecular addition of N–C annulation to synthesize isoquinolin-1­(2<i>H</i>)-ones has been developed. A wide range of α-bromo ketones with different substituents proceeded smoothly in this reaction, and varieties of isoquinolin-1­(2<i>H</i>)-one derivatives were obtained in moderate to good yields

    An efficient, green, and novel method for the synthesis of N-heterocycle-fused quinoxalines is reported herein. Dimethyl sulfoxide was used as both a reactant and a solvent in this reaction. A wide range of products in moderate to excellent yields were obtained, including pyrrolo­[1,2-<i>a</i>]­quinoxalines, indolo­[1,2-<i>a</i>]­quinoxalines, 1<i>H</i>-pyrrolo­[3,2-<i>c</i>]­quinolines, and benzo­[4,5]­imidazo­[1,2-<i>c</i>]­quinazolines
