A validated self-administered questionnairethat included 13 attitudes and 14 barrier items was used as a tool. The reliabilityof the tool was 0.89 (Cronbach's alpha). In the analysis of attitude scores, responseswere rated on a scale from 0 to 4, with 0 representing 'strongly disagree'and 4 representing 'strongly agree' for supportive attitudes towards organdonation. Participants with a total attitude score of 39 or higher indicated agreementor strong agreement with all items, reflecting a generally supportiveattitude toward organ donation. Lower scores suggested that the respondent wasneutral or disagreed with one or more items, indicating a less supportive attitudetoward organ donation. Knowledge about organ donation was assessed by selfadministeredquestionnaire that included 13 items. Analysis was done using SPSSversion 29. χ2 was used to assess associations between variables.RESULTSMost participants were young (≤ 30 years old, 83.7%), female (79.2%), from World Health Organization Eastern Mediterranean Region countries (69.5%), Muslim (82.4%), students (80.6%), single(83.9%), and from a nursing college (33.1%). The majority had no personal or family history of organ donation(93.2% and 93.9%, respectively). Supportive attitudes toward organ donation were significantly associated withreligion (P = 0.003), working status (P = 0.009), university (P = 0.019), and knowledge (P < 0.001). Additionally,those with a personal or family history of organ donation were significantly more supportive (56.8% vs 33.3%, P =0.004). Lack of awareness was the most reported barrier for organ donation (64.1%) followed by being afraid oforgan donation due to medical procedures required (51.9%).CONCLUSIONThe findings suggest that supportive attitudes toward organ donation are influenced by demographic factors,personal experiences, and knowledge levels. Lack of awareness and fear of medical procedures were the mostreported barriers to organ donation. These results highlight the need for targeted educational programs to increaseawareness and promote positive attitudes toward organ donation.展开更多

文摘Liver transplantation is a vital intervention for patients with end-stage liver disease;however,the Arab world faces significant barriers that hinder access to this life-saving procedure in terms of both practice and research.This narrative review explores the multifaceted challenges,including financial constraints,limited healthcare infrastructure,cultural factors,and the prevalence of infectious diseases.In the Arab countries,both culture and religion were found to play major roles in the acceptability of liver transplantation.High rates of misconceptions and financial strain on patients and healthcare systems necessitate more transplantation programs and improved financial coverage and insurance policies.Enhancing healthcare facilities and improving access to innovative technologies through research is essential for optimizing transplantation outcomes,considering that common diseases in the region decrease the donor pool and increase complication risks.Public health initiatives to prevent and control prevalent liver diseases,particularly hepatitis,and to manage infection risk are also critical.Stricter regulations should be enforced in less developed countries in the region along with early screening practices to address inherited blood disorders and infectious diseases.Additionally,targeted research on liver diseases specific to the Arab context is crucial,along with fostering dialogue about cultural,religious,economic,and health-related factors affecting donor and recipient eligibility.By tackling these complex barriers through targeted comprehensive strategies,the Arab world can advance to a more equitable and effective liver transplantation system,ultimately improving patient outcomes and quality of life.

文摘This paper proposes a reliability evaluation model for a multi-dimensional network system,which has potential to be applied to the internet of things or other practical networks.A multi-dimensional network system with one source element and multiple sink elements is considered first.Each element can con-nect with other elements within a stochastic connection ranges.The system is regarded as successful as long as the source ele-ment remains connected with all sink elements.An importance measure is proposed to evaluate the performance of non-source elements.Furthermore,to calculate the system reliability and the element importance measure,a multi-valued decision diagram based approach is structured and its complexity is analyzed.Finally,a numerical example about the signal transfer station system is illustrated to analyze the system reliability and the ele-ment importance measure.

文摘BACKGROUNDLimited research exists on attitudes and barriers to organ donation in the UnitedArab Emirates, highlighting the need for a deeper understanding of public perceptionsand challenges.AIMTo assess the attitudes and barriers toward organ donation.METHODSA cross-sectional study was adopted and included 607 samples consisting ofstudents, faculty, and staff who were selected from three universities in Ajmanand who had signed consent forms. A validated self-administered questionnairethat included 13 attitudes and 14 barrier items was used as a tool. The reliabilityof the tool was 0.89 (Cronbach's alpha). In the analysis of attitude scores, responseswere rated on a scale from 0 to 4, with 0 representing 'strongly disagree'and 4 representing 'strongly agree' for supportive attitudes towards organdonation. Participants with a total attitude score of 39 or higher indicated agreementor strong agreement with all items, reflecting a generally supportiveattitude toward organ donation. Lower scores suggested that the respondent wasneutral or disagreed with one or more items, indicating a less supportive attitudetoward organ donation. Knowledge about organ donation was assessed by selfadministeredquestionnaire that included 13 items. Analysis was done using SPSSversion 29. χ2 was used to assess associations between variables.RESULTSMost participants were young (≤ 30 years old, 83.7%), female (79.2%), from World Health Organization Eastern Mediterranean Region countries (69.5%), Muslim (82.4%), students (80.6%), single(83.9%), and from a nursing college (33.1%). The majority had no personal or family history of organ donation(93.2% and 93.9%, respectively). Supportive attitudes toward organ donation were significantly associated withreligion (P = 0.003), working status (P = 0.009), university (P = 0.019), and knowledge (P < 0.001). Additionally,those with a personal or family history of organ donation were significantly more supportive (56.8% vs 33.3%, P =0.004). Lack of awareness was the most reported barrier for organ donation (64.1%) followed by being afraid oforgan donation due to medical procedures required (51.9%).CONCLUSIONThe findings suggest that supportive attitudes toward organ donation are influenced by demographic factors,personal experiences, and knowledge levels. Lack of awareness and fear of medical procedures were the mostreported barriers to organ donation. These results highlight the need for targeted educational programs to increaseawareness and promote positive attitudes toward organ donation.

文摘Objectives To investigate the barriers and facilitators influencing the sustainable implementation of evidence-based practice(EBP)for Peristomal Irritant Contact Dermatitis(PICD)based on the Consolidated Framework for Implementation Research(CFIR).Methods The sample consisted of 17 nurses from three urology wards at a tertiary hospital in Beijing,China,who had participated in the EBP.Guided by the CFIR,we identified constructs influencing the sustainability of implementation by conducting a directed content analysis of the 17 individual in-depth interviews.By rating,the valence and magnitude of each construct were determined.Results This study identified 19 factors across the five domains of the CFIR.Among these determinants,16 were identified as barriers,while three were recognized as facilitators.Common barriers across different contexts were identified,such as delayed evidence updating,the complexity of intervention components and steps,and incompatibility between the implementation process and clinical practices.In contrast,facilitators of intervention implementation were regular communication and feedback,support and drive from principals and a positive cultural atmosphere.In addition,we identified“regular evidence updating”as an independent construct outside of the CFIR,a finding that will provide key information for updating the CFIR framework.Conclusions Regular evidence updating is crucial for the sustainability of EBP implementation.Researchers should receive consistent feedback from practitioners and adjust or modify the EBP as necessary.Additionally,researchers must consider the compatibility or adaptability of the EBP’s content with clinical practice in formulating it rather than adding additional complexity to the original workflow.

文摘Constructing multi-dimensional hydrogen bond(H-bond)regulated single-molecule systems with multiemission remains a challenge.Herein,we report the design of a new excited-state intramolecular proton transfer(ESIPT)featured chromophore(HBT-DPI)that shows flexible emission tunability via the multidimensional regulation of intra-and intermolecular H-bonds.The feature of switchable intramolecular Hbonds is induced via incorporating several hydrogen bond acceptors and donors into one single HBT-DPI molecule,allowing the“turn on/off”of ESIPT process by forming isomers with distinct intramolecular Hbonds configurations.In response to different external H-bonding environments,the obtained four types of crystal/cocrystals vary in the contents of isomers and the molecular packing modes,which are mainly guided by the intermolecular H-bonds,exhibiting non-emissive features or emissions ranging from green to orange.Utilizing the feature of intermolecular H-bond guided molecular packing,we demonstrate the utility of this fluorescent material for visualizing hydrophobic/hydrophilic areas on large-scale heterogeneous surfaces of modified poly(1,1-difluoroethylene)(PVDF)membranes and quantitatively estimating the surface hydrophobicity,providing a new approach for hydrophobicity/hydrophilicity monitoring and measurement.Overall,this study represents a new design strategy for constructing multi-dimensional hydrogen bond regulated ESIPT-based fluorescent materials that enable multiple emissions and unique applications.
