Background and Aims: Highly cited papers (HCPs) can influence both research and clinical practice. They help to identify core literature and important advances in a field. This study aimed to assess the current status and prospects of South Asia COVID-19 research from the HCPs using bibliometric indicators. Methodology: COVID-19 literature from South Asia published between December 2019 and 29 November 2023 in the Scopus database was analysed. The top HCPs, having more than 200 citations, were evaluated. Information about citation counts, authors and organisations and their affiliations, year of publication, source journal, geographical origin, subject, article type, funding details, etc. were retrieved and analysed. Data and visualisation analysis was undertaken using Microsoft Excel and other bibliometric software. Results: The 298 South Asia HCPs were published from 2020 to 2023 and were cited 200–3,596 times, with a mean average of 413.9 citations per paper (CPP). Around 24.5% and 51.3% of HCPs received external funding support and were involved in international collaboration, respectively. The most productive organisations were the Postgraduate Institute of Medical Education and Research, Chandigarh, and the Indian Institute of Technology, New Delhi, while the most impactful organisations were Bai Jerbai Wadia Hospital for Children, Mumbai, and Kokilaben Dhirubhai Ambani Hospital & Medical Research Institute, Mumbai. The most productive journals were Diabetes and Metabolic Syndrome: Clinical Research & Reviews. Conclusions: This study has identified core and significant authors, organisations, journals, subject fields and significant keywords, collaborators and funding agencies involved in South Asia's COVID-19 research.

Background: Unhealthy diet is a key risk factor for Non-Communicable Diseases (NCDs) that contribute to increased morbidity and premature mortality. With increased computer literacy and mobile phone penetration, there is a high opportunity for mobile application-based interventions. The current study was conducted to develop a mobile application to monitor dietary intake and to assess its acceptability and effectiveness in diet control compared to a similar paper-based intervention. A mobile application was developed based on research evidence and opinions of local experts. The mobile application was introduced to a selected group of office workers who were in preparation, action, and maintenance stages of the Trans Theoretical Model (TTM) and a paper-based intervention was used as the comparator. Socio-demographic data were collected through a self-administered questionnaire. Participants were followed up for three months for adherence. The effectiveness of interventions was assessed at the end of three months by comparing the progressive change in the stage of change and the change from unhealthy to healthy dietary intake between two groups as primary and secondary outcomes respectively. Results: Among 123 office workers who participated in the study, 19.5% preferred the mobile intervention over the paper-based intervention. Younger, unmarried office workers and those who do not have children, had a higher acceptance for the mobile intervention (p < 0.05). There was no difference in adherence (in all three months) or outcomes between the two groups of intervention. Conclusion and recommendations: Mobile application-based interventions are better accepted among the young age group and further studies are recommended to explore their applicability. Trial registration: The study was registered in the Sri Lankan Clinical Trial Registry (Registration No. SLCTR/2020/025; Date 15th December 2020). [ABSTRACT FROM AUTHOR]

In research, outcomes are often categorized as primary and secondary. The primary outcome is the most important one; it determines whether the study is considered 'successful' or not. Secondary outcomes are chosen because they provide supporting evidence for the results of the primary outcome or additional information about the subject being studied. For reasons that are explained in this paper, secondary outcomes should be cautiously interpreted. There are varying practices regarding publishing secondary outcomes. Some authors publish these separately, while others include them in the main publication. In some contexts, the former can lead to concerns about the quality and relevance of the data being published. In this article, we discuss primary and secondary outcomes, the importance and interpretation of secondary outcomes, and considerations for publishing multiple outcomes in separate papers. We also discuss the special case of secondary analyses and post hoc analyses and provide guidance on good publishing practices. Throughout the article, we use relevant examples to make these concepts easier to understand. While the article is primarily aimed at early career researchers, it offers insights that may be helpful to researchers, reviewers, and editors across all levels of expertise. [ABSTRACT FROM AUTHOR]

Purpose: This paper outlines the theoretical and empirical basis for compassion focused therapy (CFT) for psychosis, the gaps in the current knowledge and research, as well as some of the challenges for addressing gaps. It will guide the direction of future work and the steps needed to develop and advance this approach. Method: This paper reviews evidence of how evolutionary models such as social rank theory and attachment theory have greatly contributed to our understanding of psychosis and provide a clear rationale and evidence base for the mechanisms of change in CFT for psychosis. It reviews the evidence for outcomes of compassion training more generally, and early feasibility evaluations of CFT for psychosis. Results: The process evidence shows that people with psychosis have highly active social rank and threat systems, and the benefits of switching into attachment and care systems, which can support emotion regulation and integrative mind states. The outcomes evidence shows that compassion training impacts not only psychological outcomes, but also physiological outcomes such as neural circuits, immune system, and the autonomic nervous system. Within the psychosis field, outcomes research is still in the early days, but there are good indications of feasibility and a clear path forward for the next steps. Conclusions: CFT for psychosis is an approach that integrates biopsychosocial processes, an integration that's evidenced across each aspect of the model, from theoretical foundations (evolution‐informed) to interventions (e.g., body/breath training and relational techniques), to evaluation. Future RCTs are required to understand the effects on biopsychosocial outcomes for people with psychosis. [ABSTRACT FROM AUTHOR]

Identifying factors that associate with more cited or higher quality research may be useful to improve science or to support research evaluation. This article reviews evidence for the existence of such factors in article text and metadata. It also reviews studies attempting to estimate article quality or predict long‐term citation counts using statistical regression or machine learning for journal articles or conference papers. Although the primary focus is on document‐level evidence, the related task of estimating the average quality scores of entire departments from bibliometric information is also considered. The review lists a huge range of factors that associate with higher quality or more cited research in some contexts (fields, years, journals) but the strength and direction of association often depends on the set of papers examined, with little systematic pattern and rarely any cause‐and‐effect evidence. The strongest patterns found include the near universal usefulness of journal citation rates, author numbers, reference properties, and international collaboration in predicting (or associating with) higher citation counts, and the greater usefulness of citation‐related information for predicting article quality in the medical, health and physical sciences than in engineering, social sciences, arts, and humanities.

Open data as an integral part of the open science movement enhances the openness and sharing of scientific datasets. Nevertheless, the normative utilization of data journals, data papers, scientific datasets, and data citations necessitates further research. This study aims to investigate the citation practices associated with data papers and to explore the role of data papers in disseminating scientific datasets. Dataset accession numbers from NCBI databases were employed to analyze the prevalence of data citations for data papers from PubMed Central. A dataset citation practice identification rule was subsequently established. The findings indicate a consistent growth in the number of biomedical data journals published in recent years, with data papers gaining attention and recognition as both publications and data sources. Although the use of data papers as citation sources for data remains relatively rare, there has been a steady increase in data paper citations for data utilization through formal data citations. Furthermore, the increasing proportion of datasets reported in data papers that are employed for analytical purposes highlights the distinct value of data papers in facilitating the dissemination and reuse of datasets to support novel research.

- Abstract
Objective: Media are a main source of medical information for the public, as well as for decision makers. This scenario demands a good selection of stories and correct medical reporting. Design: Our study aimed to analyze if journalistic guidelines or similar documents were already available and whether they provided satisfactory advice for appropriate communication in the field, and to detail recommendations which could become a reference working document. Methodology: Sources for this paper were obtained from PubMed and from websites (and related links) of organizations known to be working in the area of health reporting. Documents providing recommendations for the activity were analyzed and compared through a scheme including nine macro-categories relevant to the selection, verification and building of the story, considering scientific and journalistic issues. The scheme was derived from the most complete document. We then compiled a comprehensive list of recommendations merging the contents of the documents considered and our professional experience. Results: Nine existing guidelines and similar documents representing the worldwide situation were compared. All the documents examined provided interesting indications. Some of these indications shared the basic principles of mainstream journalism (reliability and independence of sources); others were more specific, such as the understanding of the scientific method and its jargon, the need to avoid extrapolations and to understand the difference between "in vitro" and animal studies and clinical trials, statistical parameters, and so on. Most of the topics specific for health communication are concepts which can be grasped only with an adequate scientific background and continuing education. The nature and level of the details provided by these documents vary considerably and in most cases can be fully understood only by experienced journalists with a relevant background. Discussion: Our proposal provides a useful tool listing nearly 70 recommendations ranging from the education of journalists, to all the aspects of selection, understanding and translating of medical and drug information deriving from scientific reports. It is intended for a journalist with a biomedical background, and therefore highlights critical issues without providing detailed descriptions. The proposal endeavors to answer to the main criticisms of medical journalism, particularly the use of sources, the verification of clinical value, the need to follow up on the story. Our work focuses on the prerequisite for a medical journalist to acquire the knowledge that enables him to assess the results of pharmacological and medical research in order to accurately and reliably convey his message to a lay reader. The strength of our working paper derives from the preliminary "benchmarking" of existing documents, as suggested in the literature, but even more so from the concerted effort of the authors, who represent the key stakeholders of the system (researchers, academic teachers, medical journalists and publishers). Conclusion: Our work identifies the major issues entailed in correct health reporting, and constitutes a step forward in overcoming existing barriers between scientists and journalists. The aim is to encourage the mediation of "public-centred" information, which limits the false hopes and expectations that may arise due to communication problems between the two worlds.

The purpose of this paper is to retrieve and study the highly cited papers as well as the correlation between the citation frequency and the download frequency of the 20 traditional Chinese medicine journals in China, in order to provide the guidance for improving the influence and academic quality of these journals. Bibliometric analyses were conducted on 1103 papers of 20 traditional Chinese medicine journals from 2011 to 2020 by retrieving for the China Academic Journal Network Publishing Database (CAJD) in China National Knowledge Infrastructure (CNKI). SPSS 17.0 software was used to analyze the correlation between the citation frequency and the download frequency via conducting regression fitting and establishing the mathematical models. The results showed that the total citations of the 1103 papers were 93051 times and the average citations were 84.36 times per paper. The total downloads of the 1103 papers were 2058442 times, and the average downloads were 1866.22 times per paper. China Journal of Chinese Materia Medica ranked first according to the number of papers, total citations and total downloads. The citations of Journal of Chinese Medicinal Materials ranked first based on the number of citations per paper. One of Li's paper had been cited the most (983 times). There were 629 (57.03%) papers whose first author was from universities. The scopes of the first authors were distributed in 29 regions and 2 special administrative regions (Macao, Hong Kong) in China. The authors from Beijing published 283 (25.66%) papers, ranking number one. The number of papers supported by funds was 882 (79.96%). The research results of correlation showed that the citation frequency and the download frequency of the highly cited papers had a highly positive correlation from both journal and paper level for whether the sample data of journals was normally distributed or nonnormally distributed. The correlation coefficients of the 20 journals at journal level and that at paper level were 0.9765 and 0.6677, respectively. The correlation was better at journal level than that at paper level, while the optimal regression fitting was all cubic polynomial. Among the 1103 papers, there were 684 (62.01%) research papers and 419 (37.99%) review papers. The main citation period of the top 15 papers was from the 2nd year to the 6th year after publication, accounting for 78.39%. Papers on clinical therapeutics research, papers on the pharmacological effects and its mechanism of traditional Chinese medicine, and papers on traditional Chinese medicine and natural medicine were the main source of the highly cited papers of the traditional Chinese medicine journals. Editors of the journals should focus on the above-mentioned research areas to select manuscripts for exploiting the excellent sources extensively, while paying attention to review papers, focusing on national major or key projects, paying attention to network spreading, stabilizing authors with quality services, in order to improve the influence and the academic quality of journals.

20. Comprehensive Assessment and Evaluation of Students with Learning Disabilities: A Paper Prepared by the National Joint Committee on Learning Disabilities
- Abstract
The National Joint Committee on Learning Disabilities (NJCLD) strongly supports comprehensive assessment and evaluation of students with learning disabilities by a multidisciplinary team for the identification and diagnosis of students with learning disabilities. Comprehensive assessment of individual students requires the use of multiple data sources. These sources may include standardized tests, informal measures, observations, student self-reports, parent reports, and progress monitoring data from response-to-intervention (RTI) approaches (NJCLD, 2005). Reliance on any single criterion for assessment or evaluation is not comprehensive, nor is a group assessment, such as universal screening or statewide academic assessment tests, sufficient for comprehensive assessment or evaluation. This paper is intended to inform administrators, educators, parents, and others concerned about the effective identification and education of students with learning disabilities about the components, processes, and participants necessary for comprehensive assessment and evaluation, as well as optimal practices that should further enhance the education of students with learning disabilities. The NJCLD has long recognized that inappropriate assessment and evaluation practices may result in questionable incidence rates for learning disabilities (NJCLD, 2001a). Similarly, the NJCLD (2001a, 2001b) has provided a solid foundation for addressing the issues of assessment, evaluation, identification, and eligibility of students with learning disabilities.

Background and Purpose: Patient-Reported Measured Outcomes (PROMs) are essential to gain a full understanding of a patient's condition, and in spine surgery, these questionnaires are of help when tailoring a surgical strategy. Electronic registries allow for a systematic collection and storage of PROMs, making them readily available for clinical and research purposes. This study aimed to investigate the reliability between the electronic and paper form of ODI (Oswestry Disability Index), SF-36 (Short Form Health Survey 36) and COMI-back (Core Outcome Measures Index for the back) questionnaires. Methods: A prospective analysis was performed of ODI, SF-36 and COMI-back questionnaires collected in paper and electronic format in two patients' groups: Pre-Operatively (PO) or at follow-up (FU). All patients, in both groups, completed the three questionnaires in paper and electronic form. The correlation between both methods was assessed with the Intraclass Correlation Coefficients (ICC). Results: The data from 100 non-consecutive, volunteer patients with a mean age of 55.6 ± 15.0 years were analysed. For all of the three PROMs, the reliability between paper and electronic questionnaires results was excellent (ICC: ODI = 0.96; COMI = 0.98; SF36-MCS = 0.98; SF36-PCS = 0.98. For all p < 0.001). Conclusions: This study proved an excellent reliability between the electronic and paper versions of ODI, SF-36 and COMI-back questionnaires collected using a spine registry. This validation paves the way for stronger widespread use of electronic PROMs. They offer numerous advantages in terms of accessibility, storage, and data analysis compared to paper questionnaires.

Purpose: The main objective of this study is to evaluate the impact of Persian Scientific Papers (PSPs) on Persian Wikipedia by studying Wikipedia's citations to these papers. Design/methodology/approach: The present study is applied research, which has been performed by the web-mining method, such as downloading web pages, extracting information (references), identifying papers, detecting peer-review journals and calculating the frequency rates. The statistical population included 10,000 Persian Wikipedia Pages (PWPs) that were analyzed in two rounds with a six-month interval. Findings: The number of pages containing the Persian references section was 3,994 and 4,063 out of the 10,000 pages extracted in the first and second rounds. The ratio of pages that cited scientific sources (58 and 67 pages) to the pages extracted from the PWP was equal to 0.58 and 0.67%. The ratio of pages that cited scientific sources to pages with Persian references in each round was equal to 1.45 and 1.64%. The number of references extracted from the PWP in each round equaled 30,441 and 35,891. Eight titles from reputable Persian journals had received at least three citations from Wikipedia. Originality/value: The present study has determined the extent of interaction between science and society (knowledge flow) in the form of citations from Wikipedia articles to articles in peer-reviewed journals. The study of this issue in Persian Wikipedia in more than 2000 Persian peer-reviewed journals shows the originality of the present paper. Studying citation reliability in a collaborative and openly editable platform is another originality of the work. [ABSTRACT FROM AUTHOR]

Background: There have been several papers published about pemphigus. Bibliometric analysis is useful in determining the most significant research in a certain topic. By bibliometric research, we were able to determine the 100 most frequently reference articles in pemphigus. Aims and Objective: Using bibliometric tools to find and evaluate the top 100 most reference papers in pemphigus. Materials and Methods: On 19 February 2023, the Web of Science database was utilized to launch a title-specific search. Publications were listed in degrading order on the basis of their total citations. We examined the top 100 most reference pemphigus publications. Results: The years of publication varied from 1971 to 2020, with the 1990s being the most active. According to diverse study objectives, the 100 publications were separated into clinical aspects and diagnosis (20%), pathophysiology (52%), therapy (13%), epidemiology (8%), related disorders (1%) and others (6%). The 100 papers were published in 37 different publications. The top 100 reference articles included 54 first authors of 11 nations, most of whom came from North America and Europe. Stanley, J R, from Uniformed Services University of the Health Sciences, was the principal author. Conclusions: A thorough bibliometric research of the top 100 publications in pemphigus was provided by the research, which may be useful for future research. [ABSTRACT FROM AUTHOR]

Retractions of peer-reviewed biomedical journal articles with Indian authorship have been on the rise for many years. Our study aimed to investigate the reason behind these retractions, namely plagiarism, falsification, fabrication, duplicate publication, author conflicts, ethical issues, fake peer-reviews, and data-related issues, besides providing year-wise trends regarding retraction, authorship, impact factor, and citations. We retrieved retracted publications with Indian affiliations indexed in MEDLINE between 1 January 1990 to 31 December 2021. During this period a total of 619 papers from 372 different journals with median values (interquartile range) pertaining to impact factor [3.2 (1.5, 5.2)], retraction time [24 (10, 51)] months, pre-retraction citations [4 (1, 12)], and post-retraction citations [4 (2, 12)] were retracted. While retractions still account for a small fraction of all publications (0.1%), the overall rate of retractions, that is, the number of retractions relative to the number of newly published journal articles in a given year, has been increasing. The reasons for retractions included plagiarism (27%), falsification and fabrication (26%), duplicate publication (21%), erroneous data (12%), authorship issues (4%), fake-peer reviews (3%), and ethical and funding issues (2%). We have analysed these reasons separately and compared them with each other. Besides a spurt in retraction due to plagiarism, instances of falsification have been escalating over the past decade. Half of the papers retracted on grounds of falsification were published by repeat offender authors in high-impact journals. Furthermore, 82% of retracted papers continued to accumulate citations even after the release of the journal retraction notices. The increase in retractions raises concerns over research quality as well as the wastage of scientific resources, which is especially pressing considering the present environment of scarce funding. The problem of retractions due to reasons such as plagiarism, duplicate publication, authorship issues, and, ethical issues as well as post-retraction citations can be mitigated by educating and raising awareness on publication ethics and responsible research conduct of researchers and journal publishers. Retractions due to fabrication, falsification, and fake peer reviews are more challenging to difficult to address and require further research for the identification of effective solutions.

This study examined the current approach to the inclusion of race and ethnicity among frequently referenced shoulder surgery literature and discussed guidance for best practices for the inclusion of race and ethnicity in shoulder research. The shoulder literature were systematically reviewed for the most frequently cited studies discussing rotator cuff repair, total shoulder arthroplasty, and Bankart repair. All reviewed studies met the timeline criteria (2013-2022). Only studies with clinical outcomes were included. Review articles, meta-analyses, systematic reviews, basic science studies, or any manuscript that did not represent clinical outcomes research were excluded. Author, year issued, the journal in which the paper was published, study design, the number of subjects, duration of follow-up, independent variables, dependent variables, results, and conclusions were extracted from the articles that met the inclusion criteria. Whether race and/or ethnicity were included in the study design in any way was also recorded. For those studies in which race and ethnicity were included, a detailed analysis of the paper's treatment of race using the JAMA Updated Guidance on Reporting of Race and Ethnicity in Medical and Science Journals was performed and recorded. In the "rotator cuff repair" cohort of papers, there were 2 articles that mention race. Out of the 2 articles that mentioned race, neither included race appropriately using the JAMA Updated Guidance on Reporting of Race and Ethnicity in Medical and Science Journals. In the "Bankart repair" cohort of papers, each article lacked the mention of race among their patient population. The "total shoulder arthroplasty" manuscripts also did not include treatment of race and ethnicity in any way. Race and ethnicity and other social determinants of health can be used to understand the source of healthcare disparities. Unless a thoughtful and deliberate consideration of race and ethnicity is undertaken, their inclusion in clinical research can be a double-edged sword due to the potential race and ethnicity-centered treatment involvement can be rooted in fallacies. In shoulder surgery clinical research, race and ethnicity should be considered in concert with social factors that could exacerbate poor patient outcomes in our patient population. Level V.

During the coronavirus pandemic, changes in the way science is done and shared occurred, which motivates meta‐research to help understand science communication in crises and improve its effectiveness. The objective is to study how many Spanish scientific papers on COVID‐19 published during 2020 share their research data. Qualitative and descriptive study applying nine attributes: (a) availability, (b) accessibility, (c) format, (d) licensing, (e) linkage, (f) funding, (g) editorial policy, (h) content, and (i) statistics. We analyzed 1,340 papers, 1,173 (87.5%) did not have research data. A total of 12.5% share their research data of which 2.1% share their data in repositories, 5% share their data through a simple request, 0.2% do not have permission to share their data, and 5.2% share their data as supplementary material. There is a small percentage that shares their research data; however, it demonstrates the researchers' poor knowledge on how to properly share their research data and their lack of knowledge on what is research data.

One of the most widely used measures of scientific impact is the number of citations. However, due to its heavy-tailed distribution, citations are fundamentally difficult to predict but can be improved. This study was aimed at investigating the factors and parts influencing the citation number of a scientific paper in the otology field. Therefore, this work proposes a new solution that utilizes machine learning and natural language processing to process English text and provides a paper citation as the predicted results. Different algorithms are implemented in this solution, such as linear regression, boosted decision tree, decision forest, and neural networks. The application of neural network regression revealed that papers' abstracts have more influence on the citation numbers of otological articles. This new solution has been developed in visual programming using Microsoft Azure machine learning at the back end and Programming Without Coding Technology at the front end. We recommend using machine learning models to improve the abstracts of research articles to get more citations. [ABSTRACT FROM AUTHOR]

- Abstract
Despite the recent growth of attention to English for research publication purposes, little is known about how researchers view the role of peer review in their success of publication. In light of this gap, the present study investigated Iranian surgeons' attitudes towards peer review and the challenges they face in getting their papers published. To this end, 26 Iranian surgeons were interviewed, and the transcribed data were analyzed through thematic analysis. The results revealed that firstly the surgeons attested to the positive and negative contributions of peer review in terms of changing or unchanging their attitudes, respectively. Secondly, the authors faced a myriad of challenges related to editors, reviewers, and socio-political-linguistic factors in getting their papers published. Moreover, they associated these challenges with positive and negative effects in being connected to their career-stage development and motivating them to conduct and submit more papers. The study concludes with implications for research and practice in how researchers can craft more quality papers to enhance their chance of publication in high-quality journals.

NASAL polyps , *CLINICAL immunology , *MEDICAL research , *PLACEBOS , *ALLERGIES , *COMPUTED tomography - Abstract
Nasal endoscopy is not only used for the diagnosis of chronic rhinosinusitis with nasal polyps (CRSwNP), but also for monitoring the response to therapy playing an important role in both daily practice and research. In contrast to patient‐reported outcomes, endoscopic nasal polyp scoring by independent blinded readers is an objective measurement, not influenced by the placebo effect. It is safer and cheaper compared with computed tomography imaging and therefore, better suited for regular assessments of the extent of the disease. Since the early 90s, a variety of endoscopic staging methods have been proposed and used in clinical research, making it hard to compare results from different studies. This paper resulted from a task force with experts in the field of CRSwNP, originated by the Ear, Nose and Throat section of the European Academy of Allergy and Clinical Immunology and aims to provide a unified endoscopic NP scoring system that can serve as a reference standard for researchers, but also as a useful tool for practitioners involved in the management of CRSwNP.

Background: Every year the scientific sessions of Annual National Conference of Indian Psychiatric Society (ANCIPS) are marked by presentation of free papers, posters, and award paper sessions, which are usually meant for presentation of new research which is not yet published. Hence, it is expected that these papers will be published in near future so that the scientific literature is distributed and shared with wider audience. Aim: This paper aims to evaluate the abstract to publication rate of papers presented during ANCIPS in the years 2012–2014. Materials and Methods: For this study, all the free papers, posters, and award papers presented during the ANCIPS of 2012–2014 were listed, and electronic searches were carried out to search for published articles. In addition, one of the authors of papers not found in the electronic searches were contacted through E-mail. Results: A total of 1081 papers were presented during the ANCIPS in the 3 year period under study. Of these, 64 were award papers, 622 were free papers, and 395 were posters. Majority (n = 807; 74.6%) of these could be categorized as research data-based presentations; this was followed by case reports/series (203; 18.8%), review of literature (n = 35; 3.3%), and others (n = 36; 3.3%). Overall, only 27% of the papers were published after at least 5 years of the presentation. Of all the award papers, 69.6% of papers were published, whereas only 26.8% of free oral papers and 22.5% of free posters were published. About half (45.6%) of the papers were published in national journals. In terms of indexing, among those which were published, 62.8% were published in Medline-indexed (PubMed-listed) Journals with a mean impact factor of 1. Conclusion: The present study shows that only 27% of the abstracts presented during the ANCIPS are ultimately published as full text articles in the next 5 years. [ABSTRACT FROM AUTHOR]

In this White Paper, we outline recommendations from the perspective of health psychology and behavioural science, addressing three research gaps: (1) What methods in the health psychology research toolkit can be best used for developing and evaluating digital health tools? (2) What are the most feasible strategies to reuse digital health tools across populations and settings? (3) What are the main advantages and challenges of sharing (openly publishing) data, code, intervention content and design features of digital health tools? We provide actionable suggestions for researchers joining the continuously growing Open Digital Health movement, poised to revolutionise health psychology research and practice in the coming years. This White Paper is positioned in the current context of the COVID-19 pandemic, exploring how digital health tools have rapidly gained popularity in 2020–2022, when world-wide health promotion and treatment efforts rapidly shifted from face-to-face to remote delivery. This statement is written by the Directors of the not-for-profit Open Digital Health initiative (n = 6), Experts attending the European Health Psychology Society Synergy Expert Meeting (n = 17), and the initiative consultant, following a two-day meeting (19–20th August 2021).

Institutional discovery environments now serve as central resource databases for researchers in the academic environment. Over the last several decades, there have been numerous discovery layer research inquiries centering primarily on user satisfaction measures of discovery system effectiveness. This study focuses on the creation of a largely automated method for evaluating discovery layer quality, utilizing the bibliographic sources from student research projects. Building on past research, the current study replaces a semiautomated Excel Fuzzy Lookup Add-In process with a fully scripted R-based approach, which employs the stringdist R package and applies the Jaro-Winkler distance metric as the matching evaluator. The researchers consider the error rate incurred by relying solely on an automated matching metric. They also use Open Refine for normalization processes and package the tools together on an OSF site for other institutions to use. Since the R-based approach does not require special processing or time and can be reproduced with minimal effort, it will allow future studies and users of our method to capture larger sample sizes, boosting validity. While the assessment process has been streamlined and shows promise, there remain issues in establishing solid connections between research paper bibliographies and discovery layer use. Subsequent research will focus on creating alternatives to paper titles as search proxies that better resemble genuine information-seeking behavior and comparing undergraduate and graduate student interactions within discovery environments.

Context.--Whole slide imaging (WSI) represents a paradigm shift in pathology, serving as a necessary first step for a wide array of digital tools to enter the field. Its basic function is to digitize glass slides, but its impact on pathology workflows, reproducibility, dissemination of educational material, expansion of service to underprivileged areas, and intrainstitutional and interinstitutional collaboration exemplifies a significant innovative movement with far-reaching effects. Although the benefits of WSI to pathology practices, academic centers, and research institutions are many, the complexities of implementation remain an obstacle to widespread adoption. In the wake of the first regulatory clearance of WSI for primary diagnosis in the United States, some barriers to adoption have fallen. Nevertheless, implementation of WSI remains a difficult prospect for many institutions, especially those with stakeholders unfamiliar with the technologies necessary to implement a system or who cannot effectively communicate to executive leadership and sponsors the benefits of a technology that may lack clear and immediate reimbursement opportunity. Objectives.--To present an overview of WSI technology--present and future--and to demonstrate several immediate applications of WSI that support pathology practice, medical education, research, and collaboration. Data Sources.--Peer-reviewed literature was reviewed by pathologists, scientists, and technologists who have practical knowledge of and experience with WSI. Conclusions.--Implementation of WSI is a multifaceted and inherently multidisciplinary endeavor requiring contributions from pathologists, technologists, and executive leadership. Improved understanding of the current challenges to implementation, as well as the benefits and successes of the technology, can help prospective users identify the best path for success. doi: 10.5858/arpa.2018-0343-RA, Pathology as a practice vitally relies on the accurate interpretation of microscopic images in order to correctly diagnose patients and guide therapeutic decision making.

50. Generalizing Some Key Results from 'Alternative Weighting Schemes When Performing Matching-Adjusted Indirect Comparisons'
- Author
-
Landan Zhang and Dan Jackson
- Abstract
A recent paper proposed an alternative weighting scheme when performing matching-adjusted indirect comparisons. This alternative approach follows the conventional one in matching the covariate means across two studies but differs in that it maximizes the effective sample size when doing so. The appendix of this paper showed, assuming there is one covariate and negative weights are permitted, that the resulting weights are linear in the covariates. This explains how the alternative method achieves a larger effective sample size and results in a metric that quantifies the difficulty of matching on particular covariates. We explain how these key results generalize to the case where there are multiple covariates, giving rise to a new metric that can be used to quantify the impact of matching on multiple covariates.
