Acceptability of physician associate interns in primary care: results from a service evaluation.

BACKGROUND: Physician associates (PA) form part of the policy-driven response to increased primary care demand and a general practitioner (GP) recruitment and retention crisis. However, they are novel to the primary care workforce and have limitations, for example, they cannot prescribe. The novel 1 year Staffordshire PA Internship (SPAI) scheme, introduced in 2017, was established to support the integration of PAs into primary care. PA interns concurrently worked in primary and secondary care posts, with protected weekly primary care focussed education sessions. This evaluation established the acceptability of PA interns within primary care. METHODS: All ten PAs from the first two SPAI cohorts, the nine host practices (supervising GPs and practice managers) and host practice patients were invited to participate in the evaluation. A conceptual framework for implementing interventions in primary care informed data collection and analysis. Data were gathered at three time points over the internship from practices, through discussions with the supervising GP and/or practice manager, and from the PAs via discussion groups. To enrich discussion data, PA and practices were sent brief surveys requesting information on PA/practice characteristics and PA primary care roles. Patient acceptability data were collected by the host practices. Participation at every stage was optional. RESULTS: By evaluation end, eight PAs had completed the internship. Seven PAs and six practices provided data at every time point. Five practices provided patient acceptability data. Overall PA interns were acceptable to practices and patients, however ambiguity about the PA role and how best to communicate and operationalise PA roles was revealed. An expectation-preparedness gap resulted in PAs needing high levels of supervision early within the internship. SPAI facilitated closure of the expectation-preparedness gap and its funding arrangements made the high supervision requirements more acceptable to practices. CONCLUSIONS: The test-of-concept SPAI successfully integrated new PAs into primary care. However, the identified challenges risk undermining PAs roles in primary care before they have attained their full potential. Nationally, workforce leaders should develop approaches to support new PAs into primary care, including commitments to longer-term, sustainable, cohesive and appropriately funded schemes, including structured and standardised education and supervision.

Qualifications and Characteristics North American Dental Deans Seek in Department Chairpersons.

The aim of this study was to determine whether deans of North American dental schools perceived that one category of department chairperson skills (leadership or management) was more important than the other for their chairpersons to be successful. A secondary purpose was to determine the professional qualifications and personal characteristics these deans perceived contributed most to the success of department chairpersons and whether those differed by the research emphasis of the school. An email survey was sent in 2016 to all 75 deans of U.S. and Canadian dental schools with graduating classes. Section one of the survey was an open response section asking deans to list the five most essential characteristics of a successful department chairperson. Section two asked deans to rank the importance of eight listed professional qualifications, and the last section asked deans to rate the importance of four leadership and four management traits that could contribute to the success of their chairpersons. Questions about characteristics of the deans and the schools were also included. A response rate of 46.7% was obtained. The most frequent characteristics listed in the open response section were in the categories of vision, academic expertise, and integrity. The three most highly ranked professional qualifications were previous teaching experience, previous administrative experience, and history of external research funding. Four of the eight professional qualifications were ranked differently by deans of high compared to moderate research-intensive schools (p<0.05). Overall, the respondents rated leadership skills more highly than management skills (p=0.002) as important for departmental chairpersons.

Improving a Dental School's Clinic Operations Using Lean Process Improvement.

The term "lean production," also known as "Lean," describes a process of operations management pioneered at the Toyota Motor Company that contributed significantly to the success of the company. Although developed by Toyota, the Lean process has been implemented at many other organizations, including those in health care, and should be considered by dental schools in evaluating their clinical operations. Lean combines engineering principles with operations management and improvement tools to optimize business and operating processes. One of the core concepts is relentless elimination of waste (non-value-added components of a process). Another key concept is utilization of individuals closest to the actual work to analyze and improve the process. When the medical center of the University of Kentucky adopted the Lean process for improving clinical operations, members of the College of Dentistry trained in the process applied the techniques to improve inefficient operations at the Walk-In Dental Clinic. The purpose of this project was to reduce patients' average in-the-door-to-out-the-door time from over four hours to three hours within 90 days. Achievement of this goal was realized by streamlining patient flow and strategically relocating key phases of the process. This initiative resulted in patient benefits such as shortening average in-the-door-to-out-the-door time by over an hour, improving satisfaction by 21%, and reducing negative comments by 24%, as well as providing opportunity to implement the electronic health record, improving teamwork, and enhancing educational experiences for students. These benefits were achieved while maintaining high-quality patient care with zero adverse outcomes during and two years following the process improvement project.

Social Media in the Dental School Environment, Part A: Benefits, Challenges, and Recommendations for Use.

Social media consist of powerful tools that impact not only communication but relationships among people, thus posing an inherent challenge to the traditional standards of who we are as dental educators and what we can expect of each other. This article examines how the world of social media has changed dental education. Its goal is to outline the complex issues that social media use presents for academic dental institutions and to examine these issues from personal, professional, and legal perspectives. After providing an update on social media, the article considers the advantages and risks associated with the use of social media at the interpersonal, professional, and institutional levels. Policies and legal issues of which academic dental institutions need to be aware from a compliance perspective are examined, along with considerations and resources needed to develop effective social media policies. The challenge facing dental educators is how to capitalize on the benefits that social media offer, while minimizing risks and complying with the various forms of legal constraint.

Social Media in the Dental School Environment, Part B: Curricular Considerations.

The goal of this article is to describe the broad curricular constructs surrounding teaching and learning about social media in dental education. This analysis takes into account timing, development, and assessment of the knowledge, skills, attitudes, and behaviors needed to effectively use social media tools as a contemporary dentist. Three developmental stages in a student's path to becoming a competent professional are described: from undergraduate to dental student, from the classroom and preclinical simulation laboratory to the clinical setting, and from dental student to licensed practitioner. Considerations for developing the dental curriculum and suggestions for effective instruction at each stage are offered. In all three stages in the future dentist's evolution, faculty members need to educate students about appropriate professional uses of social media. Faculty members should provide instruction on the beneficial aspects of this communication medium and help students recognize the potential pitfalls associated with its use. The authors provide guidelines for customizing instruction to complement each stage of development, recognizing that careful timing is not only important for optimal learning but can prevent inappropriate use of social media as students are introduced to novel situations.

Use of social media in dental schools: pluses, perils, and pitfalls from a legal perspective.

One of the ways dental education is changing the way it is preparing the next generation of learners is through efficient utilization of interactive social media. Social media, which facilitates interaction and sharing of new ideas, is being utilized to educate students, residents, and faculty. Unfortunately, as with most improvements in technology, there are growing pains. Faculty, student, and patient interaction on social media platforms, such as Facebook and Twitter, can lead to inappropriate or embarrassing situations. Striking the appropriate balance between free speech rights of students and faculty and the need for colleges and universities to have efficient operations is often left to the judicial system. The concepts of free speech and contract law and how each is applied in educational settings should be understood by students, faculty, and administrators. This article provides a review of legal cases that led to current social media policies, as well as present-day cases that exemplify the application of these principles, to help dental educators gain a greater understanding of the boundaries of protected speech. It also provides a set of sample guidelines for communicating through these media.

Expression of ADAMTS-1, ADAMTS-4, ADAMTS-5 and TIMP3 by hepatocellular carcinoma cell lines.

Little is known about the expression or role of ADAMTS-1, -4 and -5 and their endogenous inhibitor TIMP3 in the liver in physiological and pathological conditions. Their expression was, therefore, investigated in the hepatocellular carcinoma cell lines HepG2 and HuH-7 using qRT-PCR and western blotting, and their cellular localisation by immunocytochemistry. Cytokine treatments were used to assess mRNA and protein modulation. ADAMTS-1, -4, -5 and TIMP3 mRNA and protein were detected in both HepG2 and HuH-7 cells. IL-1ß and IL-6 treatments significantly modulated ADAMTS-1 mRNA expression and IL-1ß treatment ADAMTS-4 mRNA expression in HepG2 cells. Modulations of mRNA by ≥ 5-fold did not translate to increased protein expression. This study showed that ADAMTS-1, -4, -5 and TIMP3 were expressed at differential levels in hepatocellular carcinoma cell lines. The pro-inflammatory cytokines IL-1ß, TNF-α or IL-6 induced changes in mRNA expression, although these did not translate to the protein level.

Effects of pro-inflammatory cytokines on the production of soluble fractalkine and ADAM17 by HepG2 cells.

BACKGROUND & AIMS: Soluble fractalkine is increased in the liver during times of injury; however the effect of pro-inflammatory cytokines in this process is currently unknown. The aim of this study was to determine whether pro-inflammatory cytokines elevated in patients with hepatocellular carcinoma influence fractalkine shedding from HepG2 cells and whether ADAM17 was involved in this process. METHODS: In vitro experiments were performed in the human hepatocellular carcinoma cell line HepG2. Soluble fractalkine was detected using an ELISA. ADAM17 expression was investigated using quantitative real time (reverse transcription)-polymerase chain reaction and flow cytometry. Short interfering RNA transfection was used to down-regulate ADAM17 expression. RESULTS: Soluble fractalkine was present in supernatants of HepG2 cells, and was significantly increased by interleukin-1ß (p ≤ 0.005) and tumour necrosis factor-α (p ≤ 0.043), but not by interleukin-6 (p ≥ 0.316). This corresponded to minor increases in ADAM17 protein, but not ADAM17 mRNA, following the same treatments. However, the down-regulation of ADAM17 protein did not affect fractalkine shedding. CONCLUSIONS: This study showed that soluble fractalkine is up-regulated under inflammatory conditions associated with hepatocellular carcinoma development, but ADAM17 does not appear to be responsible for regulating this process.

A dental dean's perspective on ethical remediation of practitioners.

A dental dean reviews the recently reported work of Dr. Muriel Bebeau providing an ethics remediation program for dental professionals in Minnesota who have been referred by the Board of Dentistry for disciplinary reasons. Dean Turner notes that the program is grounded in evidence, theory, practical cases, and critical thinking--all important elements on effective professional pedagogy. Issues associated with extending this approach to other states and into predoctoral education are explored. It is concluded that the documented effectiveness of the program belie claims that ethics cannot be taught.

Dental education in a flat world: advocating for increased global collaboration and standardization.

Globalization is a broad term referring to the increasing connectivity, integration, and interdependence of economies, societies, technologies, cultures, and political and ecological spheres across the world. This position paper was developed by a working group of the 2007 American Dental Education Association (ADEA) Leadership Institute. The authors explore the effect that globalization has had on dentistry and dental education to date and hypothesize what dental education could look like in the years ahead. While the paper is written from a North American perspective, some of the authors bring international expertise and experience to the topic of global dental education in a flat world. Specific issues and barriers addressed in this position paper include variations in accreditation and licensure requirements in dental education throughout the world; the historical development of dental education models (odontology and stomatology) and the need for congruency of these models in the global environment; the competency-based model of education and its relevance to development and implementation of global dental competencies; and the slow adoption of technological advances in dental education for promoting collaborations and encouraging resource sharing among countries. These challenges are discussed as they affect the implementation of a standardized global dental education that can lead to improved access to oral health care services and better oral and overall health for the citizens of the world.

Conversion of an MMP-potent scaffold to an MMP-selective HER-2 sheddase inhibitor via scaffold hybridization and subtle P1' permutations.

A series of beta-sulfonamide piperidine hydroxamates were prepared and shown to be potent inhibitors of the human epidermal growth factor receptor-2 (HER-2) sheddase with excellent selectivity against MMP-1, -2, -3, and -9. This was achieved by exploiting subtle differences within the otherwise highly conserved S(1)(') binding pocket of the active sites within the metalloprotease family. In addition, it was discovered that the introduction of polarity to the P(1) and P(1)(') groups reduced the projected human clearance.

Strategic partnerships between academic dental institutions and communities: addressing disparities in oral health care.

BACKGROUND: A landmark report from the U.S. surgeon general identified disparities in oral health care as an urgent and high-priority problem. A parallel development in the dental education community is the growing consensus that significant curriculum reform is long overdue. METHODS: The authors performed a literature review and conducted a series of structured interviews with key institutional and community stakeholders from seven geographical regions of the United States. They investigated a wide range of partnerships between community-based dental clinics and academic dental institutions. RESULTS: On the basis of their interviews and literature review, the authors identified common themes and made recommendations to the dental community to improve access to care while enhancing the dental curriculum. CONCLUSIONS: Reducing disparities in access to oral health care and the need for reform of the dental curriculum may be addressed, in part, by a common solution: strategic partnerships between academic dental institutions and communities. Practice Implications. Organized dentistry and individual practitioners, along with other major stakeholders, can play a significant role in supporting reform of the dental curriculum and improving access to care.

Metabolism and disposition of calcimimetic agent cinacalcet HCl in humans and animal models.

The metabolism and disposition of calcimimetic agent cinacalcet HCl was examined after a single oral administration to mice, rats, monkeys, and human volunteers. In all species examined, cinacalcet was well absorbed, with greater than 74% oral bioavailability of cinacalcet-derived radioactivity in monkeys and humans. In rats, cinacalcet-derived radioactivity was widely distributed into most tissues, with no marked gender-related differences. In all animal models examined, radioactivity was excreted rapidly via both hepatobiliary and urinary routes. In humans, radioactivity was cleared primarily via the urinary route (80%), with 17% excreted in the feces. Cinacalcet was not detected in the urine in humans. The primary routes of metabolism of cinacalcet were N-dealkylation leading to carboxylic acid derivatives (excreted in urine as glycine conjugates) and oxidation of naphthalene ring to form dihydrodiols (excreted in urine and bile as glucuronide conjugates). The plasma radioactivity in both animals and humans was primarily composed of carboxylic acid metabolites and dihydrodiol glucuronides, with <1% circulating radioactivity accounting for the unchanged cinacalcet. Overall, the circulating and excreted metabolite profile of cinacalcet in humans was qualitatively similar to that observed in preclinical animal models.

Enhancing academic integrity: formulating effective honor codes.

Academic integrity continues to be of concern in higher education as the data from undergraduate schools shows an increasing prevalence of cheating behaviors and changing values of students who are entering dental education. The use of honor codes has been reported to positively influence the attitudes and behaviors of students. This paper discusses the elements of an effective and valid honor code and its possible role in enhancing the dental school environment.
