Fulltext Educational resource for antimicrobial resistance and stewardship for dentistry programmes: a research protocol

Ang CY, Dhaliwal JS, Muharram SH, Akkawi ME, Hussain Z, Rahman H, et al.

BMJ Open, 2021 07 07;11(7):e048609.
PMID: 34233993 DOI: 10.1136/bmjopen-2021-048609

INTRODUCTION: Antimicrobial resistance (AMR) is a global public and patient safety issue. With the high AMR risk, ensuring that the next generation of dentists that have optimal knowledge and confidence in the area of AMR is crucial. A systematic approach is vital to design an AMR content that is comprehensive and clinically relevant. The primary objective of this research study will be to implement a consensus-based approach to elucidate AMR content and curriculum priorities for professional dentistry programmes. This research aims to establish consensus along with eliciting opinion on appropriate AMR topics to be covered in the Bachelor of Dental Surgery syllabus.
METHODS AND ANALYSIS: A three-phase approach to validate content for curriculum guidelines on AMR will be adopted. First, literature review and content analysis were conducted to find out the available pertinent literature in dentistry programmes. A total of 23 potential literature have been chosen for inclusion within this study following literature review and analysis in phase 1. The materials found will be used to draft curriculum on antimicrobials for dentistry programmes. The next phase involves the validation of the drafted curriculum content by recruiting local and foreign experts via a survey questionnaire. Finally, Delphi technique will be conducted to obtain consensus on the important or controversial modifications to the revised curriculum.
ETHICS AND DISSEMINATION: An ethics application is currently under review with the Institute of Health Science Research Ethics Committee, Universiti Brunei Darussalam. All participants are required to provide a written consent form. Findings will be used to identify significant knowledge gaps on AMR aspect in a way that results in lasting change in clinical practice. Moreover, AMR content priorities related to dentistry clinical practice will be determined in order to develop need-based educational resource on microbes, hygiene and prudent antimicrobial use for dentistry programmes.
Fulltext Protocol for a three-phase prospective study to develop educational resource of antimicrobial resistance and stewardship for medical programme

INTRODUCTION: Antimicrobial resistance (AMR) is one of the critical medical issues of the 21st century. Medical professionals are the primary prescribers of antimicrobials; their undergraduate education of antimicrobial stewardship (AMS) is considered one of the fundamental approaches in combating the issue of AMR. This education level provides a platform to bridge any gaps in their knowledge and competency in AMS. This study aims to develop an educational resource on microbes, hygiene and prudent antimicrobial use for the undergraduate medical programme. The guideline produced will then be assimilated into the existing curriculum which will help to improve the quality of education which in turn will improve rationale as the use of antimicrobials in the future.
METHODS AND ANALYSIS: A three-step approach consensus approach will be adopted for this study for the development of a validated medical curriculum guideline on AMR. A preliminary curriculum for the programme will be drafted from reviews of published literature including syllabi as well as national and international guidelines. A total of 26 potential sources were found to be relevant, and selected for this study. Subsequently, the drafted curriculum will be subjected for validation via online surveys by various infectious disease experts. Finally, a Delphi technique will be employed to obtain consensus on heterogeneous findings to the revised curriculum. The quantitative and qualitative responses will be analysed and discussed among the panel of researchers.
ETHICS AND DISSEMINATION: This study protocol has been approved by the Institute of Health Sciences Research Ethics Committee of Universiti Brunei Darussalam (Reference: UBD/PAPRSBIHSREC/2020/124). Informed consent declaration will be collected prior to data collections as indication of agreement of participation in the study. Results will be made available to medical educators and also researchers on AMR and stewardship. The results also will be disseminated at feedback sessions to officers at Ministry of Health and Ministry of Education, Brunei Darussalam.
Fulltext Pharmacotherapeutics Applications and Chemistry of Chalcone Derivatives

Chalcones have been well examined in the extant literature and demonstrated antibacterial, antifungal, anti-inflammatory, and anticancer properties. A detailed evaluation of the purported health benefits of chalcone and its derivatives, including molecular mechanisms of pharmacological activities, can be further explored. Therefore, this review aimed to describe the main characteristics of chalcone and its derivatives, including their method synthesis and pharmacotherapeutics applications with molecular mechanisms. The presence of the reactive α,β-unsaturated system in the chalcone's rings showed different potential pharmacological properties, including inhibitory activity on enzymes, anticancer, anti-inflammatory, antibacterial, antifungal, antimalarial, antiprotozoal, and anti-filarial activity. Changing the structure by adding substituent groups to the aromatic ring can increase potency, reduce toxicity, and broaden pharmacological action. This report also summarized the potential health benefits of chalcone derivatives, particularly antimicrobial activity. We found that several chalcone compounds can inhibit diverse targets of antibiotic-resistance development pathways; therefore, they overcome resistance, and bacteria become susceptible to antibacterial compounds. A few chalcone compounds were more active than conventional antibiotics, like vancomycin and tetracycline. On another note, a series of pyran-fused chalcones and trichalcones can block the NF-B signaling complement system implicated in inflammation, and several compounds demonstrated more potent lipoxygenase inhibition than NSAIDs, such as indomethacin. This report integrated discussion from the domains of medicinal chemistry, organic synthesis, and diverse pharmacological applications, particularly for the development of new anti-infective agents that could be a useful reference for pharmaceutical scientists.
