Background To study the molecular mechanism of galvanotropism in vitro, the strength of an electric field (EF) must be controlled precisely. In this study, I present a culture system that supplies an EF of constant strength by regulating the amount of current supplied to the culture medium. Materials and Methods Voltage of the medium was recorded at two fixed points along the current flow throughout the culture period. The voltage drop between the two points was maintained at the desired value by a negative feedback circuit and an operational amplifier. Results The field strength was defined by the voltage drop and the distance between the two points, and in this system, the EF can range from 0.0005 to 15 mV/mm. Conclusions This culture system may be a useful tool to determine the nature of galvanotropism.Background Although the chondrocyte is a nonexcitable cell, there is strong interest in gaining detailed knowledge of its ion pumps, channels, exchangers, and transporters. selleck inhibitor In combination, these transport mechanisms set the resting potential, regulate cell volume, and strongly modulate responses of the chondrocyte to endocrine agents and physicochemical alterations in the surrounding extracellular microenvironment. Materials and Methods Mathematical modeling was used to assess the functional roles of energy-requiring active transport, the Na+/K+ pump, in chondrocytes. Results Our findings illustrate plausible physiological roles for the Na+/K+ pump in regulating the resting membrane potential and suggest ways in which specific molecular components of pump can respond to the unique electrochemical environment of the chondrocyte. Conclusion This analysis provides a basis for linking chondrocyte electrophysiology to metabolism and yields insights into novel ways of manipulating or regulating responsiveness to external stimuli both under baseline conditions and in chronic diseases such as osteoarthritis.Age-related macular degeneration (ARMD) is one of the prominent causes of central visual loss in the older age group in the urbanized, industrialized world. In recent years, many epidemiological studies and clinical trials have evaluated the role of antioxidants and micronutrients to prevent the progression of ARMD. In this article, we review some of these major studies. In addition, we review the absorption and bioavailability and possible undesirable effects of these nutrients after ingestion. link2 The role of genotypes and inappropriate use of these supplements are also discussed. From all the above evidence, we conclude that it may not be prudent to prescribe these formulations without a proper assessment of the individual's health and dietary status. The effectiveness of all the components in antioxidant formulations is controversial. Thus, these supplements should not be prescribed just for the purpose of providing patients some kind of therapy, which may give a false sense of mental satisfaction.
Within the Canadian competency-based medical education system, entrustable professional activities (EPAs) are used to assess residents on performed clinical duties. This study aimed to determine whether implementing a bundle of two interventions (a case-based discussion intervention and a rotation-based nudging system) could increase the number of EPA assessments that could occur for our trainees.
The authors designed an intervention bundle with two components 1) a case-based workshop where trainees discussed which EPAs could be assessed with multiple cases and 2) a nudging system wherein each trainee was reminded of EPAs that would be useful to them on each rotation in their first year. We conducted a retrospective program evaluation to compare the intervention cohort (2019) to two historical cohorts using similar EPAs (2017, 2018).
Data from 22 trainees (seven in 2017, eight in 2018, and seven in 2019) were analyzed. There was a marked increase in the total number of EPA assessments acquired in the 2019 cohort (average per resident=285.7, 95% confidence interval [CI]= 256.1 to 312.3, range= 195-350) compared to the two other years (2018 [average=132.4, 95% CI= 107.5 to 157.02, range= 107-167] and 2017 [70.1, 95% CI 45.3 to 91.0, range= 49-95]), yielding an effect size of Cohen's
= 4.02 for our intervention bundle.
Within the limitations of a small sample size, there was a strong effect of introducing two interventions (a case-based orientation and a nudging system) upon EPA assessments with PGY-1 residents. These strategies may be useful to others seeking to improve EPA assessment numbers in other specialties and clinical environments.

There is a clear need for physician leaders with expertise in wellness given the high incidence of physician burnout, especially during the COVID-19 pandemic. A fellowship in physician wellness provides structured opportunity for the development of expertise in the science and administration of physician wellness through a tailored curriculum and academic scholarship.
Currently, limited opportunities exist to pursue formal wellness training in graduate medical education. This lack of specific training may make the path to expertise and leadership in physician wellness difficult.
Our objective was to design and implement a physician wellness fellowship in a department of emergency medicine. Completion of this fellowship, with ongoing professional development, will give physicians the skills to fill various leadership roles within the house of medicine, such as chief wellness officer, department, organization, national wellness leader, or wellness consultant.
The fellowship curriculum was developed acco may be adopted in other medical specialties at other institutions.
Outcomes of this novel program will be measured over time. Although the format of this fellowship is designed for emergency medicine, the skills and content are relevant to and may be adopted in other medical specialties at other institutions.
Clinical competence is an essential component of the practice of emergency medicine (EM), but a well-rounded physician must gain appreciation and understanding of the many nonclinical aspects of EM, including emergency department (ED) throughput, operational metrics, financial principles, policies and procedures, interaction with nursing, and patient experience. link3 While most residency programs include an administrative component, the majority are during the final year of training. We designed and piloted the Resident Exposure To Nursing and Administration (RETNA) curriculum for postgraduate year one (PGY-1) residents during orientation. The curriculum included a lecture, departmental tour with operational focus, and nurse shadowing experience, which were completed prior to their first clinical shift. We hypothesized that residents would view this favorably and advocate for formal adoption of the RETNA curriculum. Furthermore, we anticipated that the curriculum would improve relationships between residents andnd adoption of similar curricula to enhance and supplement existing postgraduate EM resident education.
Beginning in 1999, residents in emergency medicine have been expected to demonstrate competence in the six Accreditation Council on Graduate Medical Education (ACGME) Core Competencies. Expectations were further refined and clarified through the introduction of the Milestones in 2013. Emerging research and data from milestone reporting has illustrated the need for modification of the original milestones. Against this backdrop, the ACGME convened a committee to review and revise the original milestones.
The working group was convened in December 2018 and consisted of representatives from the American Board of Emergency Medicine, American Osteopathic Association, Council of Residency Directors in Emergency Medicine, Association of American Medical Colleges, ACGME-Emergency Medicine Review Committee, three community members, a resident member, and a public member. This group also included members from both academic and community emergency medicine programs. The group was overseen by the ACGME vice president for milestones development and met in person one time followed by four virtual sessions to revise and draft the Emergency Medicine Milestones and Supplemental Guide as part of the ACGME Milestones 2.0 Project.
Using data from milestones reporting, needs assessment data, stakeholder interviews, and community commentary, the working group engaged in revisions and updates for the Emergency Medicine Milestones and created a supplemental guide to aid programs in the design of programmatic assessment for the milestones.
The Emergency Medicine Milestones 2.0 provide updated specialty-specific, competency-based behavioral anchors to guide the assessment of residents, the design of curricula, and the advancement of emergency medicine training programs.

Didactic lectures remain common in medical education. Many faculty physicians do not receive formal training on public presentations or leading instructional sessions. Coaching has emerged in medical education with the potential to positively impact skills. We sought to evaluate a novel, national faculty peer-coaching program created to improve lecture presentation skills and foster career development.
This was a mixed-methods study of participant and faculty perceptions after completing the Council of Residency Directors in Emergency Medicine Academy Coaching Program. Participants completed an online evaluative survey consisting of multiple choice and Likert-type items. Program coaches participated in semistructured interviews. Descriptive statistics were reported for survey data. Thematic qualitative analysis by two independent reviewers was performed on interview data.
During 2012 to 2017, a total of 30 participants and 11 coaches from 37 residency programs across the United States engaged in the prois novel, national faculty coaching program. With identification of the success, challenges, and suggestions for improvement, others may benefit as they develop coaching programs in medical education.

Pediatric emergency medicine (PEM) has seen little progression toward a standardized PEM educational framework. The 2018
Consensus Conference on Advancing PEM Education addressed this gap in core EM education. Absent elements include a "broad needs assessment to identify and evaluate existing curricula and systems gaps in EM training" and a "clearly defined core PEM curriculum that unifies and drives the learning process." PEM education innovators were called to construct a "unified foundation in PEM education for all levels of emergency care" and to "promote innovation in teaching and learning strategies in curricula." We endeavored to meet this challenge at our institution.
The PEM curriculum design is based on the Kern model of curriculum development and included a needs assessment, development of goals and objectives, educational strategies, implementation, evaluation, and programmatic feedback. We committed to using effective learning strategies and active learning methods in developing our curriculum and conducted a 1-year pilot within our EM residency's didactic conference.
