Project description:Practice-based research is a challenge as clinicians are busy with their patients and any participation in research activities will be secondary to the needs of the patients and the clinic. As a result, it is difficult to obtain high compliance among clinicians. A method to enhance compliance in multicentre practice-based research has been developed and refined for use in the chiropractic setting and possibly also by other researchers in different settings.This manual provides a stringent step-by-step approach for conducting clinic-based research. It describes the competencies and requirements of an effective working group, how to recruit participating clinicians and how to empower, encourage and support these clinicians to obtain good compliance.The main advantage of the method is the high compliance of participating clinicians compared to many other clinical studies. Difficulties with the method are described and suggestions for solutions are presented.This manual is a description of a method that may be of use for clinical researchers in the chiropractic setting.

Project description:Chemical biology and drug discovery are two scientific activities that pursue different goals but complement each other. The former is an interventional science that aims at understanding living systems through the modulation of its molecular components with compounds designed for this purpose. The latter is the art of designing drug candidates, i.e., molecules that act on selected molecular components of human beings and display, as a candidate treatment, the best reachable risk benefit ratio. In chemical biology, the compound is the means to understand biology, whereas in drug discovery, the compound is the goal. The toolbox they share includes biological and chemical analytic technologies, cell and whole-body imaging, and exploring the chemical space through state-of-the-art design and synthesis tools. In this article, we examine several tools shared by drug discovery and chemical biology through selected examples taken from research projects conducted in our institute in the last decade. These examples illustrate the design of chemical probes and tools to identify and validate new targets, to quantify target engagement in vitro and in vivo, to discover hits and to optimize pharmacokinetic properties with the control of compound concentration both spatially and temporally in the various biophases of a biological system.

Project description:The purpose of this study was to determine whether there is adherence to the October 2011 American Academy of Pediatrics (AAP) recommendations for HIV screening in a large urban adolescent program with availability of a publicly funded program providing free, confidential, sexually transmitted infection (STI) and HIV counseling and testing (then rapid or third generation HIV testing), nested in the same adolescent clinic.We conducted a retrospective chart review of HIV screening trends among 13- to 24-year-old patients tested for HIV during periods of January 2010 to June 2011 (18 months pre-AAP recommendations period) and July 2011 to December 2012 (18-month period, which included 15 months after the AAP recommendations).During the period of January 2010 to June 2011, there were 22 tests/1,000 medical visits (N = 824 of 37,520 medical visits), and during the period of July 2011 to December 2012, there were 27 tests/1,000 medical visits (N = 1,068 of 38,763 medical visits) (p < 0.0001, odds ratio [OR] 1.26). The number of 13- to 18-year-old patients screened in the pre-AAP period was 150, compared to 297 in the second 18-month period (X 2 = 43.3, df = 1, p < 0.0001). A summative risk profile score of 0-9 was created in the form of a continuous variable, with a risk score of 0 for those with no risk factor identified and 1 point for each risk behavior identified. The proportion of HIV test clients with zero-specified risk (a risk score of "0") increased from 2010 to 2012.Release of the 2011 AAP HIV testing guidelines was associated with a modest increase in HIV screening and a shift toward testing younger people and away from risk-based screening.

Project description:BackgroundFrench community pharmacists are facing an increasing demand to provide a wider range of services to meet the needs of the population. These new missions must be evaluated by primary care research studies. This study aims to explore the factors that influence French community pharmacists' willingness to participate in research projects.MethodsA mixed-method design was adopted for this study, comprising an initial quantitative online survey followed by semi-directed interviews. The investigation was conducted at two French faculties of pharmacy, Angers and Nantes, involving students in their 6th and final year of pharmacy education, and their community pharmacist tutors. The survey items were based on a study by Saini et al. and participants responded using five-point Likert scales. The semi-directed interviews were conducted after the quantitative analysis, only with volunteer and already graduated community pharmacists.ResultsA total of 131 people participated in the quantitative analysis, comprising 75 students and 56 pharmacists. Pharmacists and students agreed on the significance of two key aspects: the research must possess a clear and meaningful purpose, and researchers must keep the pharmacists informed about the study's results. Among the 27 proposed items, only three showed significantly different results between students and pharmacists. Moreover, 11 semi-structured interviews were conducted. Research in the community pharmacy domain is relatively new for many pharmacists. Despite limited training, their willingness to participate is contingent on being actively involved from the outset, receiving appropriate support and training. However, the research should be seamlessly integrated into their daily practice, without being too time-consuming and administratively burdensome. Time constraints emerged as the main obstacle, along with concerns about the availability of human resources. Pharmacists expressed strong motivation driven by the research topic's relevance, and its potential impact on patients or the profession. While financial compensation is desirable, it did not appear to be the main criterion for participation in a study.ConclusionsFrench pharmacists are willing to participate in research projects to improve patient care and develop the profession. Research teams must guide and involve from the project's inception.

Project description:Since the widespread use of exogenous lung surfactant to treat neonatal respiratory distress syndrome, premature infant survival and respiratory morbidity have dramatically improved. Despite the effectiveness of the animal-derived surfactant preparations, there still remain some concerns and difficulties associated with their use. This has prompted investigation into the creation of synthetic surfactant preparations. However, to date, no clinically used synthetic formulation is as effective as the natural material. This is largely because the previous synthetic formulations lacked analogues of the hydrophobic proteins of the lung surfactant system, SP-B and SP-C, which are critical functional constituents. As a result, recent investigation has turned toward the development of a new generation of synthetic, biomimetic surfactants that contain synthetic phospholipids along with a mimic of the hydrophobic protein portion of lung surfactant. In this Account, we detail our efforts in creating accurate mimics of SP-C for use in a synthetic surfactant replacement therapy. Despite SP-C's seemingly simple structure, the predominantly helical protein is extraordinarily challenging to work with given its extreme hydrophobicity and structural instability, which greatly complicates the creation of an effective SP-C analogue. Drawing inspiration from Nature, two promising biomimetic approaches have led to the creation of rationally designed biopolymers that recapitulate many of SP-C's molecular features. The first approach utilizes detailed SP-C structure-activity relationships and amino acid folding propensities to create a peptide-based analogue, SP-C33. In SP-C33, the problematic and metastable polyvaline helix is replaced with a structurally stable polyleucine helix and includes a well-placed positive charge to prevent aggregation. SP-C33 is structurally stable and eliminates the association propensity of the native protein. The second approach follows the same design considerations but makes use of a non-natural, poly-N-substituted glycine or "peptoid" scaffold to circumvent the difficulties associated with SP-C. By incorporating unique biomimetic side chains in a non-natural backbone, the peptoid mimic captures both SP-C's hydrophobic patterning and its helical secondary structure. Despite the differences in structure, both SP-C33 and the SP-C peptoid mimic capture many requisite features of SP-C. In a surfactant environment, these analogues also replicate many of the key surface activities necessary for a functional biomimetic surfactant therapy while overcoming the difficulties associated with the natural protein. With improved stability, greater production potential, and elimination of possible pathogenic contamination, these biomimetic surfactant formulations offer not only the potential to improve the treatment of respiratory distress syndrome but also the opportunity to treat other respiratory-related disorders.

Project description:Pharmacogenomics (i.e., the application of genetic information in predicting an individual's response to drug therapy) plays an increasingly important role in drug development and decision-making regarding precision medicine. This has been shown to reduce the risk of adverse events and improve patient health-care outcomes through targeted therapies and dosing. As the field of pharmacogenomics rapidly evolves, the role of pharmacists in the education, implementation, and research applications of pharmacogenomics is becoming increasingly recognized. This paper aims to provide an overview and current perspectives of pharmacogenomics in contemporary clinical pharmacy practice and to discuss the future directions on advancing pharmacogenomics education, application, and research in pharmacy practice.

Project description:BACKGROUND: The Accreditation Council for Graduate Medical Education (ACGME) requires residency programs to meet and demonstrate outcomes across 6 competencies. Measuring residents' competency in practice-based learning and improvement (PBLI) is particularly challenging. PURPOSE: We developed an educational tool to meet ACGME requirements for PBLI. The PBLI template helped programs document quality improvement (QI) projects and supported increased scholarly activity surrounding PBLI learning. METHODS: We reviewed program requirements for 43 residency and fellowship programs and identified specific PBLI requirements for QI activities. We also examined ACGME Program Information Form responses on PBLI core competency questions surrounding QI projects for program sites visited in 2008-2009. Data were integrated by a multidisciplinary committee to develop a peer-protected PBLI template guiding programs through process, documentation, and evaluation of QI projects. All steps were reviewed and approved through our GME Committee structure. RESULTS: An electronic template, companion checklist, and evaluation form were developed using identified project characteristics to guide programs through the PBLI process and facilitate documentation and evaluation of the process. During a 24 month period, 27 programs have completed PBLI projects, and 15 have reviewed the template with their education committees, but have not initiated projects using the template. DISCUSSION: The development of the tool generated program leaders' support because the tool enhanced the ability to meet program-specific objectives. The peer-protected status of this document for confidentiality and from discovery has been beneficial for program usage. The document aggregates data on PBLI and QI initiatives, offers opportunities to increase scholarship in QI, and meets the ACGME goal of linking measures to outcomes important to meeting accreditation requirements at the program and institutional level.

Project description:We present a global time series of street-network sprawl-that is, sprawl as measured through the local connectivity of the street network. Using high-resolution data from OpenStreetMap and a satellite-derived time series of urbanization, we compute and validate changes over time in multidimensional street connectivity measures based on graph-theoretic and geographic concepts. We report on global, national, and city-level trends since 1975 in the street-network disconnectedness index (SNDi), based on every mapped node and edge in the world. Streets in new developments in 90% of the 134 most populous countries have become less connected since 1975, while just 29% show an improving trend since 2000. The same period saw a near doubling in the relative frequency of a street-network type characterized by high circuity, typical of gated communities. We identify persistence in street-network sprawl, indicative of path-dependent processes. Specifically, cities and countries with low connectivity in recent years also had relatively low preexisting connectivity in our earliest time period. We discuss implications for policy intervention in road building in new and expanding cities as a top priority for sustainable urban development.

Project description:BackgroundSurveys measuring effectiveness of public awareness campaigns in reducing cardiovascular disease (CVD) incidence have yielded equivocal findings. The aim of this study was to describe cardiovascular risk factors (CVRFs) changes over the years in an untreated population-based study.MethodsBetween 2007 and 2012, we conducted a screening campaign for CVRFs in men aged 40 to 65 yrs and women aged 50 to 70 yrs in the western suburbs of Paris. Data were complete for 20,324 participants of which 14,709 were untreated.ResultsThe prevalence trend over six years was statistically significant for hypertension in men from 25.9% in 2007 to 21.1% in 2012 (p=0.002) and from 23% in 2007 to 12.7% in 2012 in women (p<0.0001). The prevalence trend of tobacco smoking decreased from 38.6% to 27.7% in men (p=0.0001) and from 22.6% to 16.8% in women (p=0.113). The Framingham 10-year risk for CVD decreased from 13.3 ± 8.2 % in 2007 to 11.7 ± 9.0 % in 2012 in men and from 8.0 ± 4.1 % to 5.9 ± 3.4 % in women. The 10-year risk of fatal CVD based on the European Systematic COronary Risk Evaluation (SCORE) decreased in men and in women (p <0.0001).ConclusionsOver a 6-year period, several CVRFs have decreased in our screening campaign, leading to decrease in the 10-year risk for CVD and the 10-year risk of fatal CVD. Cardiologists should recognize the importance of community prevention programs and communication policies, particularly tobacco control and healthier diets to decrease the CVRFs in the general population.

Project description:Urban transformations form a central challenge for enabling global pathways towards sustainability and resilience. However, it remains unclear what kind of capacity is needed to deliver urban change that is actually transformative. Against a backdrop of current claims and efforts to achieve urban transformations, this special issue reviews the relational concept of urban transformative capacity and how it can inform novel approaches in research, policy, and practice. Drawing on seven papers analyzing diverse empirical contexts, we identify four requirements that should guide future action: (1) foster inclusion and empowerment as prerequisites, (2) close the intermediation gap and strengthen the role of local academia, (3) challenge and reinvent urban planning as a key arena, and (4) enhance reflexivity through novel self-assessment techniques. Overall, current levels of urban transformative capacity are assessed as very low, making its development a high-priority objective for all stakeholders, but for planning and research policy in particular.
