RESUMO

This article was migrated. The article was marked as recommended. Medical residents in difficulty struggle to comply with educational requirements. They pose a liability to patient safety and they have problems to adapt to the professional role of a doctor. Consequently, being a resident in difficulty may cause identity crisis and have the potential to disrupt the resident's professional identity as a doctor. Only few studies explore the tipping point between becoming a resident in difficulty or not, and these studies rarely reflect the surrounding sociocultural aspects of the residents' difficulties such as organisational culture in the workplace. This article explores how medical residency training culture influence on residents' risk of ending in difficulty. Our study was based on six focus-group interviews with residents (n=28) and in-depth interviews with residents in difficulty (n=10). The interpretation of data employed sociologist Pierre Bourdieu's theoretical framework around dispositions. Across the data, we identified four themes: Conflicting games in the field of medical education, altruism, organisational hierarchy, and coping with stress. We found a (mis)match between legitimate rules in the field of medicine and the residents' dispositions to appreciate those rules. These results can inform clinical supervisors and consultants in their decisions for supporting residents in difficulty and increasing educational achievement among struggling residents.

RESUMO

CONTEXT: Over recent decades, the use of qualitative methodologies has increased in medical education research. These include ethnographic approaches, which have been used to explore complex cultural norms and phenomena by way of long-term engagement in the field of research. Often, however, medical education consists of short-term episodes that are not bound to single sites, but take place in a myriad of locations and contexts such as classrooms, examination stations, clinical settings and online. This calls for methodologies that allow us to grasp what is at stake in an increasingly multifaceted and diverse field. METHODS: In this article, we direct attention to focused ethnography, which has emerged as a useful, suitable and feasible applied qualitative research approach, and which uses adapted classic ethnographic methods, such as direct observation, to gain new insights and nuanced understandings of distinct phenomena, themes and interactions in specific settings in medical education (eg the learning potential of ward rounds, or how hierarchical positions affect learning situations). We introduce methodological key features of focused ethnography to give insights into how the approach can be used, and we offer examples of how the method has been used in medical education research to show how it has contributed in different ways to the field of medical education research. Furthermore, we address and discuss some of the main challenges and limitations of the approach. CONCLUSIONS: Focused ethnography offers a methodological approach that sheds light over limited and well-defined social episodes and interactions. Precisely because the field of medical education consists to a large degree of such fragmented interactions, focused ethnography can be seen as a methodology tailored to these characteristics and should become an integrated part of the toolkit of medical education research.

RESUMO

Recent years have seen leading medical educationalists repeatedly call for a paradigm shift in the way we view, value and use subjectivity in assessment. The argument is that subjective expert raters generally bring desired quality, not just noise, to performance evaluations. While several reviews document the psychometric qualities of the Multiple Mini-Interview (MMI), we currently lack qualitative studies examining what we can learn from MMI raters' subjectivity. The present qualitative study therefore investigates rater subjectivity or taste in MMI selection interview. Taste (Bourdieu 1984) is a practical sense, which makes it possible at a pre-reflective level to apply 'invisible' or 'tacit' categories of perception for distinguishing between good and bad. The study draws on data from explorative in-depth interviews with 12 purposefully selected MMI raters. We find that MMI raters spontaneously applied subjective criteria-their taste-enabling them to assess the candidates' interpersonal attributes and to predict the candidates' potential. In addition, MMI raters seemed to share a taste for certain qualities in the candidates (e.g. reflectivity, resilience, empathy, contact, alikeness, 'the good colleague'); hence, taste may be the result of an ongoing enculturation in medical education and healthcare systems. This study suggests that taste is an inevitable condition in the assessment of students' performance. The MMI set-up should therefore make room for MMI raters' taste and their connoisseurship, i.e. their ability to taste, to improve the quality of their assessment of medical school candidates.

RESUMO

OBJECTIVES: The purpose of this study is to explore the habitual constraints and opportunities that affect how experienced clinicians learn new skills and, in particular, how new ways of teaching can influence these. METHODS:   We conducted a case study based on a specialized training program for colonoscopy services in Denmark. Data was obtained from a short-term ethnographic fieldwork and in-depth interviews during this program. Participants were 12 experienced colonoscopists and three expert colonoscopy trainers from Denmark and UK. The analysis of data involved categorization, inductive coding, and theoretical reading inspired by sociological theory. RESULTS: The experienced clinicians' responsiveness to training was shaped by an underlying logic of colonoscopy practice that was characterized by tacit skills, routine work, lower status, skepticism and self-protectiveness. In order to overcome these habitual constraints, the trainers applied a pedagogical approach based on four methods: 1) intellectualization: 'academization' of skills and competencies, 2) sensing and scaffolding: hands-on experiences and learning by doing, 3) asymmetry: accentuating the authority and respect of the trainer, and 4) relation-building: building relationship and engagement between trainer and clinician. This multi-dimensional approach to teaching enabled the trainers to affect the clinicians' logic of practice and to create buy-in (so-called illusio). CONCLUSIONS: Clinical skills include socially constructed behaviors and unconscious competences which affect experienced clinicians' responsiveness to continuing medical education. This study suggests four educational strategies that may help trainers to establish new logics of practice in experienced clinicians and to improve the clinicians' conscious competence.

RESUMO

BACKGROUND: The majority of studies on prevalence and characteristics of residents in difficulty have been conducted in English-speaking countries and the existing literature may not reflect the prevalence and characteristics of residents in difficulty in other parts of the world such as the Scandinavian countries, where healthcare systems are slightly different. The aim of this study was to examine prevalence and characteristics of residents in difficulty in one out of three postgraduate medical training regions in Denmark, and to produce both a quantifiable overview and in-depth understanding of the topic. METHODS: We performed a mixed methods study. All regional residency program directors (N = 157) were invited to participate in an e-survey about residents in difficulty. Survey data were combined with database data on demographical characteristics of the background population (N = 2399) of residents, and analyzed statistically (Chi-squared test (Χ (2)) or Fisher's exact test). Secondly, we performed a qualitative interview study involving three focus group interviews with residency program directors. The analysis of the interview data employed qualitative content analysis. RESULTS: 73.2 % of the residency program directors completed the e-survey and 22 participated in the focus group interviews. The prevalence of residents in difficulty was 6.8 %. We found no statistically significant differences in the prevalence of residents in difficulty by gender and type of specialty. The results also showed two important themes related to the workplace culture of the resident in difficulty: 1) belated and inconsistent feedback on the resident's inadequate performance, and 2) the perceived culturally rooted priority of efficient patient care before education in the workplace. These two themes were emphasized by the program directors as the primary underlying causes of the residents' difficulty. CONCLUSIONS: More work is needed in order to clarify the link between, on the one hand, observable markers of residents in difficulty and, on the other hand, immanent processes and logics of practice in a healthcare system. From our perspective, further sociological and pedagogical investigations in educational cultures across settings and specialties could inform our understanding of and knowledge about pitfalls in residents' and doctors' socialization into the healthcare system.

RESUMO

In this article, we present a case study of residents' clinical experiences and communication in outpatient oncology consultations. We apply positioning theory, a dynamic alternative to role theory, to investigate how oncology residents and patients situate themselves as persons with rights and duties. Drawing from seven qualitative interviews and six days of observation, we investigate the residents' social positioning and their conversations with patients or supervisors. Our focus is on how (a) relational shifts in authority depend on each situation and its participants; (b) storylines establish acts and positions and narratively frame what participants can expect from a medical consultation viewed as a social episode; and (c) the positioning of rights and duties can lead to misunderstandings and frustrations. We conclude that residents and patients locate themselves in outpatient conversations as participants who jointly produce and are produced by patients' and nurses' storylines about who should take responsibility for treatment.

RESUMO

Existing pharmacological inhibitors for nicotinamide phosphoribosyltransferase (NAMPT) are promising therapeutics for treating cancer. By using medicinal and computational chemistry methods, the structure-activity relationship for novel classes of NAMPT inhibitors is described, and the compounds are optimized. Compounds are designed inspired by the NAMPT inhibitor APO866 and cyanoguanidine inhibitor scaffolds. In comparison with recently published derivatives, the new analogues exhibit an equally potent antiproliferative activity in vitro and comparable activity in vivo. The best performing compounds from these series showed subnanomolar antiproliferative activity toward a series of cancer cell lines (compound 15: IC50 0.025 and 0.33 nM, in A2780 (ovarian carcinoma) and MCF-7 (breast), respectively) and potent antitumor in vivo activity in well-tolerated doses in a xenograft model. In an A2780 xenograft mouse model with large tumors (500 mm(3)), compound 15 reduced the tumor volume to one-fifth of the starting volume at a dose of 3 mg/kg administered ip, bid, days 1-9. Thus, compounds found in this study compared favorably with compounds already in the clinic and warrant further investigation as promising lead molecules for the inhibition of NAMPT.

RESUMO

The histone deacetylase inhibitor belinostat is being evaluated clinically as a single agent in the treatment of peripheral T-cell lymphomas and in combination with other anticancer agents to treat a wide range of human cancers including acute leukemias and solid tumors. To determine the pharmacokinetics of belinostat in the NCI ODWG liver dysfunction study, we developed and validated an LC-MS/MS assay for the quantitation of belinostat and five major metabolites in 0.05 mL human plasma. After protein precipitation, chromatographic separation was achieved with a Waters Acquity BEH C18 column and a linear gradient of 0.1% formic acid in acetonitrile and water. Detection with an ABI 4000Q mass spectrometer utilized both electrospray positive and negative mode ionization. The assay was linear from 30 to 5000 ng/mL for all six analytes and proved to be accurate (92.0-104.4%) and precise (CV <13.7%), and fulfilled FDA criteria for bioanalytical method validation. We demonstrated the suitability of this assay for measuring parent drug and five major metabolites in plasma from a patient who was administered belinostat IV at a dose of 400 mg/m(2). The LC-MS/MS assay that has been developed will be an essential tool to further define the metabolism and pharmacology of belinostat in the ongoing liver organ dysfunction as well as other studies that investigate belinostat with other anticancer agents.

RESUMO

BACKGROUND: Inhibitors of nicotinamide phosphoribosyltransferase (NAMPT) are promising cancer drugs currently in clinical trials in oncology, including APO866, CHS-828 and the CHS-828 prodrug EB1627/GMX1777, but cancer cell resistance to these drugs has not been studied in detail. METHODS: Here, we introduce an analogue of CHS-828 called TP201565 with increased potency in cellular assays. Further, we describe and characterize a panel of cell lines with acquired stable resistance towards several NAMPT inhibitors of 18 to 20,000 fold compared to their parental cell lines. RESULTS: We find that 4 out of 5 of the resistant sublines display mutations of NAMPT located in the vicinity of the active site or in the dimer interface of NAMPT. Furthermore, we show that these mutations are responsible for the resistance observed. All the resistant cell lines formed xenograft tumours in vivo. Also, we confirm CHS-828 and TP201565 as competitive inhibitors of NAMPT through docking studies and by NAMPT precipitation from cellular lysate by an analogue of TP201565 linked to sepharose. The NAMPT precipitation could be inhibited by addition of APO866. CONCLUSION: We found that CHS-828 and TP201565 are competitive inhibitors of NAMPT and that acquired resistance towards NAMPT inhibitors can be expected primarily to be caused by mutations in NAMPT.

RESUMO

Optimization of the anticancer activity for a class of compounds built on a 1,3-dihydroindole-2-one scaffold was performed. In comparison with recently published derivatives of oxyphenisatin the new analogues exhibited an equally potent antiproliferative activity in vitro and improved tolerability and activity in vivo. The best compounds from this series showed low nanomolar antiproliferative activity toward a series of cancer cell lines (compound (S)-38: IC(50) of 0.48 and 2 nM in MCF-7 (breast) and PC3 (prostate), respectively) and potent antitumor effects in well tolerated doses in xenograft models. The racemic compound (RS)-38 showed complete tumor regression at a dose of 20 mg/kg administered iv on days 1 and 7 in a PC3 rat xenograft.

RESUMO

The design, synthesis, and structure-activity relationship (SAR) of a series of novel nonpeptidic cyclic phosphon- and phosphinamide-based hydroxamic acids as inhibitors of matrix metalloproteinases MMP-1, MMP-3, and MMP-9 are presented. Based on modelling studies and X-ray analysis, a model of the binding mode of these novel compounds in the MMP active site was obtained. This model provided a rational explanation for the observed SAR data, which included a systematic study of different S1' directed substituents, zinc-complexing groups, chirality, and variation of the cyclic phosphon- and phosphinamide rings. The in vivo effect of four compounds in a human fibrosarcoma mouse model (HT1080) was evaluated and compared to that of a reference compound, Prinomastat. Inhibition of tumour growth was observed for all four compounds.
