Arthur Conan Doyle's medical and writing careers intertwined and his work has a history of being read in the light of his medical expertise. He wrote at a time when the professionalisation and specialisation of medicine had resulted in an increasing distance between the profession and the public, yet general practitioners relied financially on maintaining good relationships with their patients and popular medical journalism proliferated. A variety of contrasting voices often disseminated narratives of medical science. These conflicting developments raised questions of authority and expertise in relation to the construction of medicine in the popular imagination: how is knowledge constructed? Who should disseminate it? How and by whom is authority conferred? How can the general population judge experts in medical science? These are questions explored more widely in Conan Doyle's writing as he examines the relationship between expertise and authority. In the early 1890s, Conan Doyle wrote for the popular, mass-market periodical His contributions to it address these questions of authority and expertise for a lay audience. First establishing the medical context of doctor/patient relationships in which these questions arose, this article undertakes a close reading of these mostly rarely studied single-issue stories and articles as a means of ascertaining how Conan Doyle and his illustrators identified the relationship between competing narratives, expertise and authority. It argues that rather than maintaining a distance between public and professional, Conan Doyle's illustrated work demonstrates to his readers that there are ways to successfully navigate the appearance of authority and recognise expertise as they confront entangled representations of advances in medical science.

BACKGROUND
Social networks have become one of the main channels for obtaining health information. However, they have also become a source of health-related misinformation, which seriously threatens the public's physical and mental health. Governance of health-related misinformation can be implemented through topic identification of rumors on social networks. However, little attention has been paid to studying the types and routes of dissemination of health rumors on the internet, especially rumors regarding health-related information in Chinese social media.
OBJECTIVE
This study aims to explore the types of health-related misinformation favored by WeChat public platform users and their prevalence trends and to analyze the modeling results of the text by using the Latent Dirichlet Allocation model.
METHODS
We used a web crawler tool to capture health rumor-dispelling articles on WeChat rumor-dispelling public accounts. We collected information from health-debunking articles posted between January 1, 2016, and August 31, 2022. Following word segmentation of the collected text, a document topic generation model called Latent Dirichlet Allocation was used to identify and generalize the most common topics. The proportion distribution of the themes was calculated, and the negative impact of various health rumors in different periods was analyzed. Additionally, the prevalence of health rumors was analyzed by the number of health rumors generated at each time point.
RESULTS
We collected 9366 rumor-refuting articles from January 1, 2016, to August 31, 2022, from WeChat official accounts. Through topic modeling, we divided the health rumors into 8 topics, that is, rumors on prevention and treatment of infectious diseases (1284/9366, 13.71%), disease therapy and its effects (1037/9366, 11.07%), food safety (1243/9366, 13.27%), cancer and its causes (946/9366, 10.10%), regimen and disease (1540/9366, 16.44%), transmission (914/9366, 9.76%), healthy diet (1068/9366, 11.40%), and nutrition and health (1334/9366, 14.24%). Furthermore, we summarized the 8 topics under 4 themes, that is, public health, disease, diet and health, and spread of rumors.
CONCLUSIONS
Our study shows that topic modeling can provide analysis and insights into health rumor governance. The rumor development trends showed that most rumors were on public health, disease, and diet and health problems. Governments still need to implement relevant and comprehensive rumor management strategies based on the rumors prevalent in their countries and formulate appropriate policies. Apart from regulating the content disseminated on social media platforms, the national quality of health education should also be improved. Governance of social networks should be clearly implemented, as these rapidly developed platforms come with privacy issues. Both disseminators and receivers of information should ensure a realistic attitude and disseminate health information correctly. In addition, we recommend that sentiment analysis-related studies be conducted to verify the impact of health rumor-related topics.

INTRODUCTION
Quality of life (QoL) greatly influences the outcomes of patients with mental illnesses and there is evidence that there is an association between QoL and the relapse of Opioid Use Disorder (OUD). However, no reviews elucidate the relationship between QoL and the relapse of OUD. This document provides a scoping review protocol that aims to systematically chart and synthesise the published, unpublished and grey literature about the relationship between QoL and relapse of OUD.
METHODS AND ANALYSIS
The enhanced six-stage methodological framework for scoping reviews of Arksey and O'Malley will be used. The main research question guiding the review will be: What is the relationship between QoL and relapse of OUD? Peer-reviewed and non-peer-reviewed articles, reports, and policy documents will be eligible to be included in the review with no limits on publication date. PubMed, PsycINFO, Google Scholar, Scopus, OVID and Cochrane Library will be among the databases searched. We shall identify grey literature from Google Scholar, ProQuest database, Grey Source Index, Open Grey and OpenDOAR. The reporting of the review will follow the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. Criteria for evidence inclusion and exclusion will be used during literature screening and mapping.
ETHICS AND DISSEMINATION
Patients and the public will not be involved in the interpretations of the findings, therefore, we shall not seek approval from an ethics committee. Results will be disseminated through publication in a peer-reviewed, scientific journal, conference presentations.

Review
BACKGROUND
Evidence-based practice (EBP) involves making clinical decisions based on three sources of information: evidence, clinical experience and patient preferences. Despite popularization of EBP, research has shown that there are many barriers to achieving the goals of the EBP model. The use of artificial intelligence (AI) in healthcare has been proposed as a means to improve clinical decision-making. The aim of this paper was to pinpoint key challenges pertaining to the three pillars of EBP and to investigate the potential of AI in surmounting these challenges and contributing to a more evidence-based healthcare practice. We conducted a selective review of the literature on EBP and the integration of AI in healthcare to achieve this.
CHALLENGES WITH THE THREE COMPONENTS OF EBP
Clinical decision-making in line with the EBP model presents several challenges. The availability and existence of robust evidence sometimes pose limitations due to slow generation and dissemination processes, as well as the scarcity of high-quality evidence. Direct application of evidence is not always viable because studies often involve patient groups distinct from those encountered in routine healthcare. Clinicians need to rely on their clinical experience to interpret the relevance of evidence and contextualize it within the unique needs of their patients. Moreover, clinical decision-making might be influenced by cognitive and implicit biases. Achieving patient involvement and shared decision-making between clinicians and patients remains challenging in routine healthcare practice due to factors such as low levels of health literacy among patients and their reluctance to actively participate, barriers rooted in clinicians' attitudes, scepticism towards patient knowledge and ineffective communication strategies, busy healthcare environments and limited resources.
AI ASSISTANCE FOR THE THREE COMPONENTS OF EBP
AI presents a promising solution to address several challenges inherent in the research process, from conducting studies, generating evidence, synthesizing findings, and disseminating crucial information to clinicians to implementing these findings into routine practice. AI systems have a distinct advantage over human clinicians in processing specific types of data and information. The use of AI has shown great promise in areas such as image analysis. AI presents promising avenues to enhance patient engagement by saving time for clinicians and has the potential to increase patient autonomy although there is a lack of research on this issue.
CONCLUSION
This review underscores AI's potential to augment evidence-based healthcare practices, potentially marking the emergence of EBP 2.0. However, there are also uncertainties regarding how AI will contribute to a more evidence-based healthcare. Hence, empirical research is essential to validate and substantiate various aspects of AI use in healthcare.

Bacterial translocation from the gut microbiota is a source of sepsis in susceptible patients. Previous work suggests that overgrowth of gut pathobionts, including Klebsiella pneumoniae, increases the risk of disseminated infection. Our data from a human dietary intervention study found that, in the absence of fiber, K. pneumoniae bloomed during microbiota recovery from antibiotic treatment. We thus hypothesized that dietary nutrients directly support or suppress colonization of this gut pathobiont in the microbiota. Consistent with our study in humans, complex carbohydrates in dietary fiber suppressed the colonization of K. pneumoniae and allowed for recovery of competing commensals in mouse models. In contrast, through ex vivo and in vivo modeling, we identified simple carbohydrates as a limiting resource for K. pneumoniae in the gut. As proof of principle, supplementation with lactulose, a nonabsorbed simple carbohydrate and an FDA-approved therapy, increased colonization of K. pneumoniae. Disruption of the intestinal epithelium led to dissemination of K. pneumoniae into the bloodstream and liver, which was prevented by dietary fiber. Our results show that dietary simple and complex carbohydrates were critical not only in the regulation of pathobiont colonization but also disseminated infection, suggesting that targeted dietary interventions may offer a preventative strategy in high-risk patients.

Horizontal transfer of F-like plasmids by bacterial conjugation is responsible for disseminating antibiotic resistance and virulence determinants among pathogenic Enterobacteriaceae species, a growing health concern worldwide. Central to this process is the conjugative F pilus, a long extracellular filamentous polymer that extends from the surface of plasmid donor cells, allowing it to probe the environment and make contact with the recipient cell. It is well established that the F pilus can retract to bring mating pair cells in tight contact before DNA transfer. However, whether DNA transfer can occur through the extended pilus has been a subject of active debate. In this study, we use live-cell microscopy to show that while most transfer events occur between cells in direct contact, the F pilus can indeed serve as a conduit for the DNA during transfer between physically distant cells. Our findings enable us to propose a unique model for conjugation that revises our understanding of the DNA transfer mechanism and the dissemination of drug resistance and virulence genes within complex bacterial communities.

BACKGROUND
Dental pain is common yet understudied and often undertreated in youth. To improve pain management in pediatric dentistry, it is necessary to understand practices and perceptions among providers. The authors assessed pediatric dentists' use of and attitudes toward evidence-based pain management (EBPM) strategies.
METHODS
The authors used a 27-item online survey to assess attitudes about EBPM, pain management and assessment practices, tools for disseminating knowledge about EBPM, and opinions regarding priority areas for improving pain management. Descriptive statistics were used to summarize findings; open-ended items were analyzed thematically.
RESULTS
Participants (N = 625) were pediatric dentists (89.2%) and pediatric dentistry residents (10.8%). Most respondents agreed that pain management is an important aspect of clinical care and thought that improvements in pain management practices are needed. Providers reported spending the most time facilitating pain management during the procedure (compared with before or after), and 73.2% said they feel this is an adequate amount of time. Distraction, tell-show-do techniques, and supportive language were the most used nonpharmacologic pain management strategies, and providers' observational approaches were used most frequently for pain assessment. Top priority areas for improving pain management were reported as developing tools for caregivers and provider resources on nonpharmacologic pain management (ie, continuing education courses).
CONCLUSIONS
Providers reported high use of EBPM strategies, low use of validated pain assessment tools, and a particular interest for professional development opportunities and patient resources focused on nonpharmacologic pain management.
PRACTICAL IMPLICATIONS
Findings from this survey can inform dissemination and implementation of science efforts to improve pain management in pediatric dentistry.

The global crisis in antimicrobial resistance continues to grow. Estimating the risks of antibiotic resistance transmission across habitats is hindered by the lack of data on mobility and habitat-specificity. Metagenomic samples of 6092 are analyzed to delineate the unique core resistomes from human feces and seven other habitats. This is found that most resistance genes (≈85%) are transmitted between external habitats and human feces. This suggests that human feces are broadly representative of the global resistome and are potentially a hub for accumulating and disseminating resistance genes. The analysis found that resistance genes with ancient horizontal gene transfer (HGT) events have a higher efficiency of transfer across habitats, suggesting that HGT may be the main driver for forming unique but partly shared resistomes in all habitats. Importantly, the human fecal resistome is historically different and influenced by HGT and age. The most important routes of cross-transmission of resistance are from the atmosphere, buildings, and animals to humans. These habitats should receive more attention for future prevention of antimicrobial resistance. The study will disentangle transmission routes of resistance genes between humans and other habitats in a One Health framework and can identify strategies for controlling the ongoing dissemination and antibiotic resistance.

BACKGROUND
The importance and value of involvement of people with lived experience of suicide has been recognized in suicide research and prevention. Nonetheless, clear guidance on research collaboration and co-production is lacking. This study aimed to address this gap by developing a set of guidelines on active involvement of people with lived experience of suicide in suicide studies., i.e., conducting research with or by people with lived experience, rather than to, about or for them.
METHODS
The Delphi method was used to determine statements on best practice for the active involvement of people with lived experience of suicide in suicide research. Statements were compiled through a systematic search of the scientific and grey literature, and reviewing qualitative data from a recent related study conducted by the authors. Two expert panels: people with lived experience of suicide (n = 44) and suicide researchers (n = 29) rated statements over three rounds of an online survey. Statements endorsed by at least 80% of panellists of each panel were included in the guidelines.
RESULTS
Panellists endorsed 96 out of 126 statements in 17 sections covering the full research cycle from deciding on the research question and securing funding, to conducting research and disseminating and implementing outcomes. Overall, there was a substantial level of agreement between the two panels regarding support from research institutions, collaboration and co-production, communication and shared decision making, conducting research, self-care, acknowledgment, and dissemination and implementation. However, panels also disagreed on specific statements regarding representativeness and diversity, managing expectations, time and budgeting, training, and self-disclosure.
CONCLUSIONS
This study identified consensus recommendations on active involvement of people with lived experience of suicide in suicide research, including co-production. Support from research institutions and funders, and training on co-production for researchers and people with lived experience, are needed for successful implementation and uptake of the guidelines.

Review
BACKGROUND
Dissemination of medical practice and scientific information through social media (SoMe) by clinicians and researchers is increasing. Broad exposure of information can promote connectivity within the scientific community, overcome barriers to access to sources, increase debate, and reveal layperson perspectives and preferences. On the other hand, practices lacking scientific evidence may also be promoted, laypeople may misunderstand the professional message, and clinician may suffer erosion of professional status. The aim of this project was to enhance awareness and advise the anesthesia community and clinicians at large about the potential risks advocate for responsible use of SoMe to disseminate information related to medical practices and knowledge.
METHODS
A modified Delphi process with prespecified consensus criteria was conducted among a multidisciplinary panel of experts, including anesthesiologists-intensivists, clinical psychologists, and forensic medicine specialists. Six items were identified: Ethics and deontological principles, the practice of sharing information via social media, legal aspects, psychological aspects, self-promotion, and criteria for appropriate dissemination. Statements and rationales were produced and subjected to blinded panelists' votes. After reaching consensus, a document was written which then underwent external review by experts uninvolved in the consensus process. The project was promoted by the Italian Society of Anesthesia Analgesia Resuscitation and Intensive Care (SIAARTI).
RESULTS
Twelve statements were produced, and consensus was achieved for all. The panel concluded that the general principles guiding dissemination of professional information via SoMe must remain in line with the general principles of ethics, deontology, and scientific validity that guide the medical profession and science in general. Professional equity must be maintained while communicating via SoMe. Medical practices lacking support by scientific evidence should not be disseminated. Patients' informed consent must be obtained before dissemination of information, images, or data. Self-promotion must not be prioritized over any of these principles.
CONCLUSIONS
When sharing medical practices and scientific information on SoMe, healthcare professionals are advised to act conscientiously and ethically. Local regulations should be adhered to. Institutional training on the potential risks and proper of SoMe for such purpose may contribute to preservation of professional integrity.
