Synoptic review on existing and potential sources for bias in dental research methodology with methods on their prevention and remedies

The results of years of dental study serve as the foundation for the practise of medicine and,for that matter,dentistry.Doctors may have their own preferences for techniques and materials,but whether directly or indirectly,their decisions are influenced by systematic reviews and meta-analyses.However,due to poorly conducted or presented research,this very basic foundation may not be reliable.Bias in research is one of several factors that might make study results or research itself unreliable.Bias can be introduced into research at many stages,deliberately or unknowingly.Bias can appear at any point during the research process,even before the study itself begins.There are many biases in research,but some of them are more relevant to dentistry research than others.Because it is said that“eyes see what the mind knows”,it is essential to have a complete understanding of the different types of bias,how and when they get entrenched,and what steps may be taken to prevent or lessen them if they do occur.This comprehensive summary of bias in dentistry research is provided by this synoptic review.The goal is to identify gaps and measures that have been taken-or that should have been taken-by providing both descriptive and evaluative summaries,as well as examples from the literature,when needed.

Delphi methodology in healthcare research:How to decide its appropriateness

The Delphi technique is a systematic process of forecasting using the collective opinion of panel members.The structured method of developing consensus among panel members using Delphi methodology has gained acceptance in diverse fields of medicine.The Delphi methods assumed a pivotal role in the last few decades to develop best practice guidance using collective intelligence where research is limited,ethically/logistically difficult or evidence is conflicting.However,the attempts to assess the quality standard of Delphi studies have reported significant variance,and details of the process followed are usually unclear.We recommend systematic quality tools for evaluation of Delphi methodology;identification of problem area of research,selection of panel,anonymity of panelists,controlled feedback,iterative Delphi rounds,consensus criteria,analysis of consensus,closing criteria,and stability of the results.Based on these nine qualitative evaluation points,we assessed the quality of Delphi studies in the medical field related to coronavirus disease 2019.There was inconsistency in reporting vital elements of Delphi methods such as identification of panel members,defining consensus,closing criteria for rounds,and presenting the results.We propose our evaluation points for researchers,medical journal editorial boards,and reviewers to evaluate the quality of the Delphi methods in healthcare research.

Biobanks and biomarkers:Their current and future role in biomedical research

The importance and utility of biobanks has increased exponentially since their inception and creation.Initially used as part of translational research,they now contribute over 40%of data for all cancer research papers in the United States of America and play a crucial role in all aspects of healthcare.Multiple classification systems exist but a simplified approach is to either classify as population-based or disease-oriented entities.Whilst historically publicly funded institutions,there has been a significant increase in industry funded entities across the world which has changed the dynamic of biobanks offering new possibilities but also new challenges.Biobanks face legal questions over data sharing and intellectual property as well as ethical and sustainability questions particularly as the world attempts to move to a low-carbon economy.International collaboration is required to address some of these challenges but this in itself is fraught with complexity and difficulty.This review will examine the current utility of biobanks in the modern healthcare setting as well as the current and future challenges these vital institutions face.

An Innovative Soft Design Science Methodology for Improving Development of a Secure Information System in Tanzania Using Multi-Layered Approach

This paper presents an innovative Soft Design Science Methodology for improving information systems security using multi-layered security approach. The study applied Soft Design Science Methodology to address the problematic situation on how information systems security can be improved. In addition, Soft Design Science Methodology was compounded with mixed research methodology. This holistic approach helped for research methodology triangulation. The study assessed security requirements and developed a framework for improving information systems security. The study carried out maturity level assessment to determine security status quo in the education sector in Tanzania. The study identified security requirements gap (IT security controls, IT security measures) using ISO/IEC 21827: Systems Security Engineering-Capability Maturity Model (SSE-CMM) with a rating scale of 0 - 5. The results of this study show that maturity level across security domain is 0.44 out of 5. The finding shows that the implementation of IT security controls and security measures for ensuring security goals are lacking or conducted in ad-hoc. Thus, for improving the security of information systems, organisations should implement security controls and security measures in each security domain (multi-layer security). This research provides a framework for enhancing information systems security during capturing, processing, storage and transmission of information. This research has several practical contributions. Firstly, it contributes to the body of knowledge of information systems security by providing a set of security requirements for ensuring information systems security. Secondly, it contributes empirical evidence on how information systems security can be improved. Thirdly, it contributes on the applicability of Soft Design Science Methodology on addressing the problematic situation in information systems security. The research findings can be used by decision makers and lawmakers to improve existing cyber security laws, and enact laws for data privacy and sharing of open data.

Paradigms and Methodologies for Knowledge Building

A diversity of methodologies can be utilized for knowledge building in social sciences, particularly in education. Nevertheless, in order to give meaning to the research findings and progressively create theories, an awareness of the epistemological framework appears to be necessary. The aim of this article is to present the main epistemological paradigms and their coherent correspondence with respective ontologies and corresponding methodologies. This article supports and describes four paradigms or epistemological traditions: logic empiricism, constructivism, conceptualism or Aristotelian tradition, and phenomenology. Understanding the diverse possible epistemologies as well as the coherence with methodologies is a necessary step for presenting well-informed research. Knowledge building requires comparison, replication, generalization or integration of results in theories, and all these processes need the critical instance of the epistemological and methodological coherence. Additionally some concrete examples of methodologies have been detailed to illustrate the diversity of available ways of knowledge building in education. The Review of Educational Theory, as a new journal that aims to create a scientific community, will increase the research quality by enhancing the epistemological and methodological awareness of their pieces of research.

On the Positioning, Contents, and Methodology of Human Rights Law Study

The ideal model of human rights law studies shall be one that is open and comprehensive. On the basis of normative legal studies, it shall pay more attention to and respond to political, economic, and social development in a wide range of human rights issues. These studies should attempt to find practical solutions to concrete problems. Human rights law should be a relatively independent legal discipline, and it should be a problem-oriented object of study. Regarding the research methodologies, human rights law could encompass all aspects of legal studies, and go beyond legal them to some extent to encompass the influence of other disciplines.

Factors and expectations influencing concussion disclosure within NCAA DivisionⅠathletes:A mixed methodological approach

Background:Participation in sports is associated with many benefits to all aspects of health;however,it also comes with the risk of injury,particularly concussions.Self-disclosure and care seeking following a concussion are especially important because of the lack of outwardly visible signs and/or symptoms.Although recent research has explored factors affecting concussion disclosure,use of isolated methodologies limits the ability to contextualize how disclosure or nondisclosure occurs.Therefore,the purpose of this study was to describe the factors and expectations of National Collegiate Athletic Association(NCAA)athletes that may influence concussion disclosure.Methods:This mixed-methods convergent parallel research study included 25 NCAA Division I athletes representing 13 sports,all of whom completed a concussion-education session with pre-/post-test surveys and a semistructured interview.Eligible athletes were at least 18 years old and on an NCAA roster.The surveys focused on previous concussion-related disclosure behaviors,knowledge,attitudes,beliefs,norms,and intentions about disclosing concussion.Interviews focused on the athletes’experiences related to concussion disclosure.Survey data were analyzed using descriptive statistics and Mann-Whitney U tests.Interviews were analyzed using a Consensual Qualitative Research tradition.Results:Participants had good concussion knowledge(median=46.0),positive attitudes(median=38.0),strong beliefs(median=13.0),and strong intentions to disclose concussion symptoms(median=7.0).None of the constructs differed by participants’gender.Although quantitative findings were mostly positive,interview data highlighted factors that may explain why some participants are successful in disclosing concussions and why others may find disclosure difficult.Educational efforts,sport culture,and medical professional presence were the primary facilitators discussed by participants.Stigma,pressure,and a lack of team support were perceived as disclosure barriers.Conclusion:The context in which concussion disclosure occurs or does not occur is vital to the success of educational interventions.Interventions must prioritize stakeholder-and team-based perspectives on concussion to establish a network supportive to disclosure.

The Challenges of Identifying and Managing Epistemic Inequalities in PHIR(Population Health Intervention Research):An Illustration in the Conception and Implementation of a TPE(Therapeutic Patient Education)Program in Oncology

Aims:The joint dynamics of knowledge(of patients,health professionals,decision-makers,researchers)and of the powers(of speech and action,asymmetries,and hierarchies established between individuals and their knowledge)of the people who carry them at the heart of the PHIR,are analyzed from the perspective of the management of epistemic inequalities.We study the nature of knowledge sharing or non-sharing between these different categories of agents involved in health interventions.Procedure:The qualitative methodology is based on 36 interviews and six years of ethnographic observations of the TPE program(design or implementation),as well as steering committees and workshops of the PHIR where researchers,decisionmakers,health professionals,and patients share their experiences and knowledge.Results:The research highlights three major theoretical and methodological issues of PHIR concerning epistemic inequalities.We argue for broadening the spectrum of health expertise(researchers,decision-makers,health professionals,patients)and for their pluralization.To account for the nature and evolution of collaborations,it is necessary to closely study the dynamics of the avenues of coordination between these fields of expertise.Finally,we call to identify the resources(knowledge,values,material elements,etc.)and strengths that enable these hybrid groups to bind(or not)and to potentially generate co-learning.Conclusion:Considering these three major issues allows PHIR to reflect and take action to reduce inequalities by linking epistemic and social issues.

In vitro laboratory infection research in orthopaedics:Why,when,and how

The musculoskeletal system involves multiple tissues which are constantly exposed to being exposed to various biological and mechanical stimuli.As such,isolating and studying a particular system from a complex human clinical environment is not always a realistic expectation.On top of that,recruitment limitations,in addition to the nature of orthopaedic interventions and their associated cost,sometimes preclude consideration of human trials to answer a clinical question.Therefore,in this mini review,we sought to rationalize the rapid evolution of biomedical research at a basic scientific level and explain why the perception of orthopaedic conditions has fundamentally changed over the last decades.In more detail,we highlight that the number of orthopaedic in vitro publications has soared since 1990.Last but not least,we elaborated on the minimum requirements for conducting a scientifically sound infection-related laboratory experiment to offer valuable information to clinical practitioners.We also explained the rationale behind implementing molecular biology techniques,ex vivo experiments,and artificial intelligence in this type of laboratory research.
