Addressing Equity in Global Medical Education During the COVID-19 Pandemic: The Global Medical Education Collaborative

PROBLEM

The COVID-19 pandemic has presented a unique set of challenges to medical education globally. Low- and middle-income countries (LMICs) have faced unique barriers in transitioning to virtual modalities, and many medical students in LMICs experienced dramatically reduced educational time. The authors created the Global Medical Education Collaborative (GMEC) to address this problem by providing free, online, case-based tutorials to medical students in LMICs during the pandemic.

APPROACH

The authors developed a needs assessment to gauge students' educational requirements, which informed GMEC's 2 primary goals: to provide free access to interactive online tutorials for students in LMICs and to bridge the physical distance between educators and learners via an online platform. A pilot program in Nigeria (April 26-May 26, 2020) helped inform the current strategy and logistics. Tutors and students were recruited via social media and medical education networks at the authors' home institutions.

OUTCOMES

Within the first 2 months (April 26-June 26, 2020), 324 students representing 12 countries and 20+ medical schools joined GMEC. Additionally, 95 physicians and trainees joined as tutors and, collectively, delivered 52 tutorials. Students responded to a needs assessment querying confidence in various clinical domains, interest in covering clinical topics, barriers to virtual learning, and the effect of the pandemic on their education. Tutors held 1-hour, interactive tutorials over Zoom covering a variety of clinical topics. According to surveys, 91% of students (71 of 78) felt more confident in the material related to the tutorial's topic after participating.

NEXT STEPS

GMEC will continue to engage students, tutors, and collaborators to facilitate the delivery of innovative, high-quality tutorials to students affected by COVID-19 in LMICs. To ensure that the platform is sustainable and aligned with GMEC's mission to promote equity in global medical education, the collaborative will need to be agile and responsive.

Microemulsification of essential oils for the development of antimicrobial and mosquito repellent functional coatings for textiles

AIMS

To develop an essential oil (EO)-loaded textile coating using an environmentally friendly microemulsion technique to achieve both antimicrobial and mosquito repellent functionalities.

METHODS AND RESULTS

Minimum inhibitory concentrations and fractional inhibitory concentrations of litsea, lemon and rosemary EOs were determined against Staphylococcus aureus, Escherichia coli, Staphylococcus epidermidis, Pseudomonas aeruginosa and Trichophyton rubrum. A 1 : 2 mixture of litsea and lemon EOs inhibited all the microorganisms tested and was incorporated into a chitosan-sodium alginate assembly by a microemulsification process. The EO-loaded microemulsions were applied to cotton and polyester fabrics using a soak-pad-dry method. The textile challenge tests demonstrated 7-8 log₁₀ reductions of S. epidermidis, S. aureus and E. coli after 24 h and T. rubrum after 48 h. Aedes aegypti mosquito repellency was also assessed which demonstrated 71·43% repellency compared to 52·94% by neat EO-impregnated cotton.

CONCLUSIONS

Textiles treated with the litsea and lemon EO microemulsion showed strong antimicrobial activity against the skin associated microorganisms E. coli, S. aureus, S. epidermidis and T. rubrum and potential mosquito repellent properties.

SIGNIFICANCE AND IMPACT OF THE STUDY

EOs could be useful for the development of natural, environmentally friendly functional textiles to protect textiles and users from microbial contamination in addition to possessing other beneficial properties such as mosquito repellency.

Safety and efficiency of gasless laparoscopy: a systematic review protocol

BACKGROUND

Gasless laparoscopy, developed in the early 1990s, was a means to minimize the clinical and financial challenges of pneumoperitoneum and general anaesthesia. It has been used in a variety of procedures such as in general surgery and gynecology procedures including diagnostic laparoscopy. There has been increasing evidence of the utility of gasless laparoscopy in resource limited settings where diagnostic imaging is not available. In addition, it may help save costs for hospitals. The aim of this study is to conduct a systematic review of the available evidence surrounding the safety and efficiency of gasless laparoscopy compared to conventional laparoscopy and open techniques and to analyze the benefits that gasless laparoscopy has for low resource setting hospitals.

METHODS

This protocol is developed by following the Preferred Reporting Items for Systematic review and Meta-Analysis-Protocols (PRISMA-P). The PRISMA statement guidelines and flowchart will be used to conduct the study itself. MEDLINE (Ovid), Embase, Web of Science, Cochrane Central, and Global Index Medicus (WHO) will be searched and the National Institutes of Health Clinical Trials database. The articles that will be found will be pooled into Covidence article manager software where all the records will be screened for eligibility and duplicates removed. A data extraction spreadsheet will be developed based on variables of interest set a priori. Reviewers will then screen all included studies based on the eligibility criteria. The GRADE tool will be used to assess the quality of the studies and the risk of bias in all the studies will be assessed using the Cochrane Risk assessment tool. The RoB II tool will assed the risk of bias in randomized control studies and the ROBINS I will be used for the non-randomized studies.

DISCUSSION

This study will be a comprehensive review on all published articles found using this search strategy on the safety and efficiency of the use of gasless laparoscopy. The systematic review outcomes will include safety and efficiency of gasless laparoscopy compared to the use of conventional laparoscopy or laparotomy.

TRIAL REGISTRATION

The study has been registered in PROSPERO under registration number: CRD42017078338.

Synchronous leiomyosarcoma and ameboma of the rectum: report of a case

A case of leiomyosarcoma of the rectum associated with rectal amebiasis is presented. This is the first case to be reported. Initially, amebiasis obscured the histologic diagnosis of leiomyosarcoma, but incomplete regression following a course of treatment with metronidazole aroused the suspicion of malignancy, which was confirmed on repeat biopsy. A brief review of the features of leiomyosarcoma was also undertaken.
