RESUMEN

The 2023-2024 American Association of Colleges of Pharmacy Research and Graduate Affairs Committee ("the Committee") was charged with developing programs focused on career and professional development for researchers, new faculty, and graduate students in colleges and schools of pharmacy. After reviewing exiting resources available to pharmacy faculty for grant writing, the Committee recognized a need for more comprehensive, diverse, and tailored resources for pharmacy faculty. The Committee, therefore, focused its effort on creating an intensive grant writing course intended for independent pharmacy researchers without previous major grant awards that would support writing for career development and research grant applications and cater to faculty in translational, clinical sciences, and pharmacy practice, along with fellows and residents. To implement this grant writing course and other programs to advance research progress by pharmacy faculty, the Committee proposes 3 recommendations for consideration by the American Association of Colleges of Pharmacy and 1 suggestion for consideration by colleges and schools of pharmacy.

RESUMEN

OBJECTIVE: The objective of this review is to provide the conclusions from the American Association of Colleges of Pharmacy (AACP) Council of Deans (COD) Taskforce on Research and Scholarship. FINDINGS: The charges and the findings of the committee are: (1) Define the scholarship needs/opportunities to strengthen the outputs. The committee recommends that AACP update its definitions of research/scholarship to include discovery, integration, application/practice, and teaching/learning. A deployed survey demonstrated a high Special Interest Groups research/scholarship interest. (2) Assemble a toolkit of grant and scholarship resources to assist colleges/schools. The AACP should update the existing funding opportunity listing and combine it with additional resources. (3) Create a framework for effective research collaboration and mentorship. The AACP should identify key areas of pharmacy research and experts to serve as mentors and to meet with external stakeholders. (4) and (5) Consider the need for and purpose of a COD standing committee for research and scholarship. Explore the value of a formal research dean's subcommittee. It was recommended that AACP form a research/scholarship committee or Special Interest Groups and create the Pharmacy Scholarship, Research, and Graduate Education pre-meeting to the Interim Meeting. (6) Identify key statements/outputs of the COD that need to be prepared for publication/sharing. We recommended the key statement/outputs in the areas of discovery, integration, application/practice, and teaching and learning. SUMMARY: The taskforce reviewed the state of research and scholarship across the Academy and provided recommendations with the goal of advancing research across all areas of the pharmacy profession.

RESUMEN

The American Association of Colleges of Pharmacy recognizes strategic engagement as critical to the success of pharmacy education, contributing to the expansion of pharmacy and public health practice, the fulfillment of institutional missions, and the meeting of programmatic needs. The 2022-2023 Strategic Engagement Committee or the Committee was charged with identifying ways professional advocacy is being emphasized in Doctor of Pharmacy and graduate education curricula to optimize active student engagement and share new resources for the ongoing resource guide being developed by the association. The Committee was also tasked with identifying advocacy champions at each member institution, integrating them into the work of the American Association of Colleges of Pharmacy Policy Advisory Task Force, and identifying strong advocacy partnerships between colleges and schools of pharmacy and state pharmacy organizations that can be replicated to advance the legislative or regulatory priorities of the profession. The Committee conducted a 2-part, sequential advocacy survey to identify advocacy champions at member institutions and to gain better insight into the breadth and depth of current advocacy efforts within pharmacy programs. The Committee also developed suggestions for the advocacy activities that should be required in pharmacy curricula, as well as exemplary activities identified through surveying advocacy champions.

RESUMEN

EXECUTIVE SUMMARY. The work of the 2021-2022 AACP Research and Graduate Affairs Committee (RGAC) focused on barriers to graduate education and research-related careers in pharmacy education. AACP President Stuart Haines charged the RGAC with identifying the critical barriers that hinder current PharmD students/recent graduates as well as under-represented groups (e.g., Black and Latino) from pursuing advanced degrees and research-related career paths in the pharmaceutical, social & behavioral, and clinical sciences and recommending changes that might address these barriers - this may include recommendations to change the fundamental structure of graduate education.The committee began its work with a literature review to survey current perspectives on these barriers and assess the supporting evidence for effective solutions and programs, including their relevance to pharmacy education. Based on the review, the committee was able to identify numerous obstacles to entry into and progression through research training, for both underrepresented learners and student pharmacists. Obstacles are individual, e.g., lack of exposure to and self-efficacy in research, financial constraints, structural, e.g., lengthy training time, programmatic rigidity, and institutional, e.g., implicit and explicit bias. The committee found evidence of effective approaches and programs to address these barriers that could be applied in pharmacy schools. These approaches include improvements to existing practices in recruitment, admissions and hiring practices as well as creation of new programs and structural changes to existing programs to increase accessibility to learners. The committee also recognized a need for more research and development of additional approaches to address these barriers.The committee makes a series of recommendations that AACP develop resource guides and programs to address key issues in the recruitment and retention of underrepresented students and student pharmacists into graduate education and research careers, including as faculty. The committee also proposes new AACP policies to support innovative graduate programs and early, longitudinal engagement of learners from elementary school onward to increase access to graduate education and to support environments and cultures of commitment to accessibility, diversity, equity, inclusiveness, antiracism in pharmacy education.

RESUMEN

The 2019-2020 AACP Research and Graduate Affairs Committee (RGAC) was charged with articulating the case for and evaluating the state of implementation science in academic pharmacy, given the potential for implementation science to act as a driver of practice and curricular transformation. Based on the current state of pharmacy research in this area, the RGAC was further charged with outlining a plan to raise the profile of implementation science with pharmacy leadership and defining strategies for AACP to facilitate schools in applying its methods to their practice and education missions. For this work, the RGAC considered implementation science to be the scientific study of methods and strategies to promote adoption of evidence-based practices and interventions into real world settings and routine practice, to improve the quality and effectiveness of services. The RGAC identified three components of an effective strategy for AACP to assist schools in applying implementation science in practice and education: 1) raising awareness of implementation science as an opportunity for academic pharmacy, 2) connecting pharmacy researchers with the larger implementation science community, and 3) developing pharmacy researchers in the competencies and methods associated with implementation science. Specific recommendations for this strategy were informed by searches of the literature and funding landscape related to implementation science and pharmacy. The RGAC also identified stakeholder groups that AACP could target in a campaign to raise awareness of implementation science and connectivity to the existing research community in this space, including academic leadership, faculty with expertise in relevant research methodologies (eg, the Social and Administrative Science (SAS) section of AACP), and the academic pharmacy community as a whole.

RESUMEN

The 2018-2019 Research and Graduate Affairs Committee (RGAC) was charged with critically evaluating the leadership development support necessary for pharmacy researchers, including postdoctoral trainees, to develop the skills needed to build and sustain successful research programs and analyzing how well those needs are being met by existing programs both within AACP and at other organizations. The RGAC identified a set of skills that could reasonably be expected to provide the necessary foundation to successfully lead a research team and mapped these skills to the six domains of graduate education in the pharmaceutical sciences established by the 2016-2017 RGAC (Table 1). In addition, the RGAC identified competency in team science and the bench-to-bedside-to-beyond translational spectrum as being critical elements of research leadership. The universality of these skills and their value prompted the RGAC to make two related recommendations to AACP: [Table: see text] Recommendation 1: AACP should promote the development and use of strategies to ensure intentional and ongoing professional development, such as Individual Development Plans. Recommendation 2: AACP should explore collaborative research leadership development opportunities between faculty at research-intensive institutions and faculty at non-research-intensive institutions. The RGAC also examined programs available at AACP and other national organizations that could help pharmacy faculty develop foundational skills for research leadership (Table 2). The RGAC administered two surveys, one to administrators responsible for research at colleges and schools of pharmacy and one to faculty members at pharmacy schools, to gather information about training needs, programming and support available for research leadership development. Administrators and faculty agreed that research is important for career advancement for faculty, and almost all administrators reported their schools provide funds, release time and mentoring for participation in research career development. However, a lack of faculty awareness regarding programs and available support may be a barrier to participation. The RGAC therefore makes two recommendations and one suggestion related to AACP programming: [Table: see text] Recommendation 3: AACP should expand research leadership development opportunities building from existing programs such as ALFP and AACP Catalyst, with consideration placed on developing programs that promote collaborative research. Recommendation 4: AACP should collaborate with other professional organizations to expand research leadership development opportunities across the academy. Suggestion 1: Colleges and schools of pharmacy should take a proactive role in promoting and facilitating research leadership development for faculty. The RGAC separately examined the research leadership development needs of postdoctoral trainees, recognizing the distinct needs of trainees along the PhD or PhD/PharmD, PharmD/fellowship, and PharmD/residency paths. A review of organizational resources and opportunities for post-doctoral trainees available from national organizations, including AACP, was undertaken (Table 5). The RGAC sees an opportunity for AACP to foster research development of those trainees whose career track will likely be in clinical practice and makes one recommendation and one suggestion related to postdoctoral trainees: Recommendation 5: AACP should support and/or develop programs and activities for pharmacy residents seeking to transition into faculty positions to acquire the skills necessary to develop and lead research programs. Suggestion 2: Colleges and schools of pharmacy should include postdoctoral trainees with academic interests in research leadership development opportunities available to junior faculty. In addition, the RGAC proposed one policy statement that was adopted July 2019 by the AACP House of Delegates: Policy Statement: AACP recognizes the positive role that research leadership development can play in the success of early and mid-career faculty.

RESUMEN

EXECUTIVE SUMMARY The 2017-2018 Research and Graduate Affairs Committee (RGAC) was given three charges aimed at helping academic pharmacy address barriers that must be overcome by both students and schools to attract, retain, and support the development of a diverse, well-rounded, and successful graduate student population. These charges were (1) identifying teaching methodologies, tools and opportunities that graduate programs can introduce into curriculum to overcome barriers to success of today's and tomorrow's learners; (2) developing a strategy for achieving member support of the 2016-2017 recommended graduate competencies by identifying gaps in and existing examples of courses or opportunities that achieve competency-based pharmacy graduate education; and (3) identifying potential strategies to address identified barriers to pursuing graduate education, especially among under-represented student populations. This report describes attitudes toward and opportunities related to competency-based education in graduation education in colleges and schools of pharmacy, identifies types of tools schools could use to enhance training towards the competency framework developed by the 2016-2017 RGAC, particularly with regards to the so-called power skills, and outlines a role for AACP in facilitating this training. This report also considers a number of barriers, both perceived and real, that potential students encounter when considering graduate training and suggests strategies to understand the impact of and mitigate these barriers. To strengthen competency-based graduate education, the RGAC puts forth two recommendations that AACP develop a toolkit supporting the training of power skills and that AACP should develop or curate programs or tools to support the use of individual development plans (IDPs). The RGAC also puts forth a suggestion to schools that IDPs be implemented for all students. In considering the barriers to pursuing graduate education, the Committee proposes one policy statement that AACP supports the training and development of an increasingly diverse population of researchers at pharmacy schools through active efforts to promote M.S. and Ph.D. education along with Pharm.D. education. Additionally, the Committee provides recommendations that AACP should expand its efforts in career tracking of graduate students to include collection and/or analysis of data that could inform the Academy's understanding of barriers to pursuing graduate education in pharmacy schools, the AACP Office of Institutional Research and Effectiveness should expand upon graduate program data described in the annual Profile of Pharmacy Students report, and finally that AACP should include graduate programs in efforts to increase diversity of students at pharmacy schools.

RESUMEN

Remarkable progress has recently been made in the synthesis and characterization of engineered nanoparticles for imaging and treatment of cancers, resulting in several promising candidates in clinical trials. Despite these advances, clinical applications of nanoparticle-based therapeutic/imaging agents remain limited by biological, immunological, and translational barriers. In order to overcome the existing status quo in drug delivery, there is a need for open and frank discussion in the nanomedicine community on what is needed to make qualitative leaps toward translation. In this Nano Focus, we present the main discussion topics and conclusions from a recent workshop: "Mechanisms and Barriers in Nanomedicine". The focus of this informal meeting was on biological, toxicological, immunological, and translational aspects of nanomedicine and approaches to move the field forward productively. We believe that these topics reflect the most important issues in cancer nanomedicine.

RESUMEN

Nanotechnology-enabled sensors (or nanosensors) will play an important role in enabling the progression toward ubiquitous information systems as the Internet of Things (IoT) emerges. Nanosensors offer new, miniaturized solutions in physiochemical and biological sensing that enable increased sensitivity, specificity, and multiplexing capability, all with the compelling economic drivers of low cost and high-energy efficiency. In the United States, Federal agencies participating in the National Nanotechnology Initiative (NNI) "Nanotechnology for Sensors and Sensors for Nanotechnology: Improving and Protecting Health, Safety, and the Environment" Nanotechnology Signature Initiative (the Sensors NSI), address both the opportunity of using nanotechnology to advance sensor development and the challenges of developing sensors to keep pace with the increasingly widespread use of engineered nanomaterials. This perspective article will introduce and provide background on the NNI signature initiative on sensors. Recent efforts by the Sensors NSI aimed at promoting the successful development and commercialization of nanosensors will be reviewed and examples of sensor nanotechnologies will be highlighted. Future directions and critical challenges for sensor development will also be discussed.

RESUMEN

Recent advances in cancer biology and the development of new research tools have enabled interrogations of single cells and cell-cell interactions. Emerging technologies are capable of revealing data on the physical characteristics of cells, differences in the genome and proteome between cancerous and healthy cells, and variations in distinct cell subpopulations. Dynamic measurements enable studies that can reveal the evolution of cell characteristics. Cells can also be assembled in vitro or ex vivo into two- and three-dimensional cell environments, allowing for studies of cell-cell interactions and cell signaling. The Memorial Sloan Kettering Cancer Center, in collaboration with the Breast Cancer Research Foundation and the National Cancer Institute, co-organized a workshop as an opportunity for leading researchers in their respective fields to present and discuss scientific research highlights relevant to the utilization of techniques and technologies for studying cell-to-cell communications in cancer. Avenues of future development and the potential for clinical utility were primary features of these discussions. The scientific presentations and extensive ensuing discussions resulted in the identification of a number of research opportunities, which are summarized in this report.

RESUMEN

Multicolor fluorescent labeling of both intra- and extracellular structures is a powerful technique for simultaneous monitoring of multiple complex biochemical processes. This approach remains extremely challenging, however, as it often necessitates the combinatorial use of numerous targeting probes (e.g., antibodies), multistep bioconjugation chemistries, different delivery strategies (e.g., electroporation or transfection reagents), cellular fixation coupled with membrane permeabilization, and complex spectral deconvolution. Here, we present a nanoparticle-based fluorescence labeling strategy for the multicolor labeling of distinct subcellular compartments within live cells without the need for antibody conjugation or cellular fixation/permeabilization. This multipronged approach incorporates an array of delivery strategies, which localize semiconductor quantum dots (QDs) to various subcellular structures. QD uptake is implemented in a spaciotemporal manner by staggering the delivery of QD-peptide composites and exploiting various innate (peptide-mediated endocytosis, peptide-membrane interaction, polymer-based transfection) along with physical (microinjection) cellular delivery modalities to live cells growing in culture over a 4 day period. Imaging of the different intracellular labels is simplified by the unique photophysical characteristics of the QDs in combination with Förster resonance energy transfer sensitization, which allow for multiple spectral windows to be accessed with one excitation wavelength. Using this overall approach, QDs were targeted to both early and late endosomes, the cellular cytosol, and the plasma membrane in live cells, ultimately allowing for simultaneous five-color fluorescent imaging.

RESUMEN

In this report the correlation between the solution photoluminescence (PL) quantum yield and the fluorescence emission of individual semiconductor quantum dots (QDs) is investigated. This is done by taking advantage of previously reported enhancement in the macroscopic quantum yield of water-soluble QDs capped with dihydrolipoic acid (DHLA) when self-assembled with polyhistidine-appended proteins, and by using fluorescence coincidence analysis (FCA) to detect the presence of "bright" and "dark" single QDs in solution. This allows for changes in the fraction of the two QD species to be tracked as the PL yield of the solution is progressively altered. The results clearly indicate that in a dispersion of luminescent nanocrystals, "bright" (intermittently emitting) single QDs coexist with "permanently dark" (non-emitting) QDs. Furthermore, the increase in the fraction of emitting QDs accompanies the increase in the PL quantum yield of the solution. These findings support the idea that a dispersion of QDs consists of two optically distinct populations of nanocrystals--one is "bright" while the other is "dark;" and that the relative fraction of these two populations defines the overall PL yield.

RESUMEN

The new generation of nanotechnology-based drug formulations is challenging the accepted ways of cancer treatment. Multi-functional nanomaterial constructs have the capability to be delivered directly to the tumor site and eradicate cancer cells selectively, while sparing healthy cells. Tailoring of the nano-construct design can result in enhanced drug efficacy at lower doses as compared to free drug treatment, wider therapeutic window, and lower side effects. Nanoparticle carriers can also address several drug delivery problems which could not be effectively solved in the past and include reduction of multi-drug resistance effects, delivery of siRNA, and penetration of the blood-brain-barrier. Although challenges in understanding toxicity, biodistribution, and paving an effective regulatory path must be met, nanoscale devices carry a formidable promise to change ways cancer is diagnosed and treated. This article summarizes current developments in nanotechnology-based drug delivery and discusses path forward in this field. The discussion is done in context of research and development occurring within the NCI Alliance for Nanotechnology in Cancer program.

RESUMEN

Water solubilized nanoparticles such as CdSe-ZnS core-shell nanocrystals (quantum dots, QDs) have great potential in bioimaging and sensing applications due to their excellent photophysical properties. However, the efficient modification of QDs with complex biomolecules represents a significant challenge. Here, we describe a straightforward arylhydrazone approach for the chemoselective covalent modification of QDs that is compatible with neutral pH and micromolar concentrations of the peptide target. The kinetics of covalent modification can be monitored spectroscopically at 354 nm in the presence of the QD and average peptide/QD ratios from 2:1 to 11:1 were achieved with excellent control over the desired valency. These results suggest that aniline catalyzed hydrazone ligation has the potential to provide a general method for the controlled assembly of a variety of nanoparticle-biomolecule hybrids.
