Proximity morality in medical school â medical students forming physician morality "on the job": Grounded theory analysis of a student survey
<p>Abstract</p> <p>Background</p> <p>The value of ethics education have been questioned. Therefore we did a student survey on attitudes about the teaching of ethics in Swedish medical schools.</p> <p>Methods</p> <p>Questionnaire survey on attitudes to ethics education with 409 Swedish medical students participating. We analyzed > 8000 words of open-ended responses and multiple-choice questions using classic grounded theory procedures.</p> <p>Results</p> <p>In this paper we suggest that medical students take a proximity morality stance towards their ethics education meaning that they want to form physician morality "on the job". This involves comprehensive ethics courses in which quality lectures provide "ethics grammar" and together with attitude exercises and vignette reflections nurture tutored group discussions. Goals of forming physician morality are to develop a professional identity, handling diversity of religious and existential worldviews, training students described as ethically naive, processing difficult clinical experiences, and desisting negative role modeling from physicians in clinical or teaching situations, some engaging in "ethics suppression" by controlling sensitive topic discussions and serving students politically correct attitudes.</p> <p>Conclusion</p> <p>We found that medical students have a proximity morality attitude towards ethics education. Rather than being taught ethics they want to form their own physician morality through tutored group discussions in comprehensive ethics courses.</p
Aberrant Expression of and Cell Death Induction by Engagement of the MHC-II Chaperone CD74 in Anaplastic Large Cell Lymphoma (ALCL)
SIMPLE SUMMARY: Anaplastic large cell lymphoma (ALCL) is a lymphoid malignancy considered to be derived from T cells. Currently, two types of systemic ALCL are distinguished: anaplastic lymphoma kinase (ALK)-positive and ALK-negative ALCL. Although ALK(+) and ALK(â) ALCL differ at the genomic and molecular levels, various key biological and molecular features are highly similar between both entities. We have developed the concept that both ALCL entities share a common principle of pathogenesis. In support of this concept, we here describe a common deregulation of CD74, which is usually not expressed in T cells, in ALCL. Ligation of CD74 induces cell death of ALCL cells in various conditions, and an anti-CD74-directed antibody-drug conjugate efficiently kills ALCL cell lines. Furthermore, we reveal expression of the proto-oncogene and known CD74 interaction partner MET in a fraction of ALCL cases. These data give insights into ALCL pathogenesis and might help to develop new treatment strategies for ALCL. ABSTRACT: In 50â60% of cases, systemic anaplastic large cell lymphoma (ALCL) is characterized by the t(2;5)(p23;q35) or one of its variants, considered to be causative for anaplastic lymphoma kinase (ALK)-positive (ALK(+)) ALCL. Key pathogenic events in ALK-negative (ALK(â)) ALCL are less well defined. We have previously shown that deregulation of oncogenic genes surrounding the chromosomal breakpoints on 2p and 5q is a unifying feature of both ALK(+) and ALK(â) ALCL and predisposes for occurrence of t(2;5). Here, we report that the invariant chain of the MHC-II complex CD74 or li, which is encoded on 5q32, can act as signaling molecule, and whose expression in lymphoid cells is usually restricted to B cells, is aberrantly expressed in T cell-derived ALCL. Accordingly, ALCL shows an altered DNA methylation pattern of the CD74 locus compared to benign T cells. Functionally, CD74 ligation induces cell death of ALCL cells. Furthermore, CD74 engagement enhances the cytotoxic effects of conventional chemotherapeutics in ALCL cell lines, as well as the action of the ALK-inhibitor crizotinib in ALK(+) ALCL or of CD95 death-receptor signaling in ALK(â) ALCL. Additionally, a subset of ALCL cases expresses the proto-oncogene MET, which can form signaling complexes together with CD74. Finally, we demonstrate that the CD74-targeting antibody-drug conjugate STRO-001 efficiently and specifically kills CD74-positive ALCL cell lines in vitro. Taken together, these findings enabled us to demonstrate aberrant CD74-expression in ALCL cells, which might serve as tool for the development of new treatment strategies for this lymphoma entity

Corporate image: a service recovery perspective
This article explores direct and indirect antecedents that contribute to corporate image formation in a service recovery context. Two studies were carried out in Egypt. Study 1 comprises 29 semistructured interviews with complainants of mobile phone network service providers in Egypt. Study 2 encompasses a mail survey of another 437 complainants. Findings reveal the importance of perceived justice, namely, interactional justice, in corporate image formation, as well as the mediating role of satisfaction with service recovery in the perceived justice-corporate image relationship. Results also reveal two empirical relationships: problem solving as a determinant of distributive justice and follow-up as a driver of procedural justice. Accordingly, this study contributes to the service field by providing the first empirical evaluation of new direct and indirect antecedents of corporate image formation in a service recovery context. Managerial recommendations are provided that encourage service practitioners to emphasize perceived justice and satisfaction with a service recovery process to enhance the companyâs image. Additionally, companies should invest in implementing problem solving and follow-up as service recovery strategies since both significantly enhance perceived justice
Unburdening dementia a basic social process grounded theory â based on a primary care physician survey from 25 countries
OBJECTIVE: To explore dementia management from a primary care physician perspective.DESIGN: One-page seven-item multiple choice questionnaire; free text space for every item; final narrative question of a dementia case story. Inductive explorative grounded theory analysis. Derived results in cluster analyses. Appropriateness of dementia drugs assessed by tertiary care specialist.SETTING: Twenty-five European General Practice Research Network member countries.SUBJECTS: Four hundred and forty-five key informant primary care physician respondents of which 106 presented 155 case stories.MAIN OUTCOME MEASURES: Processes and typologies of dementia management. Proportion of case stories with drug treatment and treatment according to guidelines.RESULTS: Unburdening dementia - a basic social process - explained physicians' dementia management according to a grounded theory analysis using both qualitative and quantitative data. Unburdening starts with Recognizing the dementia burden by Burden Identification and Burden Assessment followed by Burden Relief. Drugs to relieve the dementia burden were reported for 130 of 155 patients; acetylcholinesterase inhibitors or memantine treatment in 89 of 155 patients - 60% appropriate according to guidelines and 40% outside of guidelines. More Central and Northern primary care physicians were allowed to prescribe, and more were engaged in dementia management than Eastern and Mediterranean physicians according to cluster analyses. Physicians typically identified and assessed the dementia burden and then tried to relieve it, commonly by drug prescriptions, but also by community health and home help services, mentioned in more than half of the case stories.CONCLUSIONS: Primary care physician dementia management was explained by an Unburdening process with the goal to relieve the dementia burden, mainly by drugs often prescribed outside of guideline indications. Implications: Unique data about dementia management by European primary care physicians to inform appropriate stakeholders. Key points Dementia as a syndrome of cognitive and functional decline and behavioural and psychological symptoms causes a tremendous burden on patients, their families, and society. âąWe found that a basic social process of Unburdening dementia explained dementia management according to case stories and survey comments from primary care physicians in 25 countries. âąFirst, Burden Recognition by Identification and Assessment and then Burden Relief - often by drugs. âąPrescribing physicians repeatedly broadened guideline indications for dementia drugs. The more physicians were allowed to prescribe dementia drugs, the more they were responsible for the dementia work-up. Our study provides unique data about dementia management in European primary care for the benefit of national and international stakeholders
EigenstĂ€ndige Analgesie mit Piritramid durch NotfallsanitĂ€ter â retrospektive Auswertung der elektronischen Einsatzdokumentation
Hintergrund
Schmerzen sind ein hĂ€ufiger Behandlungsgrund in der prĂ€hospitalen Notfallmedizin. In Bayern delegieren die Ărztlichen Leiter Rettungsdienst (ĂLRD) bei subjektiv nichttolerablen Schmerzen nach isoliertem ExtremitĂ€tentrauma an NotfallsanitĂ€ter (NotSan) landesweit einheitlich die Kurzinfusion von 7,5âŻmg des Opioidanalgetikums Piritramid.
Methode
Die Routineeinsatzdokumentation aller EinsĂ€tze im bayerischen Rettungsdienst mit Heranziehungen des Delegationsalgorithmus âIsolierte ExtremitĂ€tenverletzungâ der ĂLRD nach § 4 Abs. 2 Nr. 2c NotfallsanitĂ€tergesetz wurde ĂŒber einen 2âJahres-Zeitraum ausgewertet. Evaluiert wurden der Effekt auf die SchmerzintensitĂ€t nach der numerischen Rating-Skala (NRS) und dem Vorliegen nichttolerabler Schmerzen, Auswirkungen auf die Vitalfunktionen sowie die Notwendigkeit von bestimmten weitergehenden Interventionen.
Ergebnisse
Bei 7151 identifizierten EinsĂ€tzen erfolgte in 6097 FĂ€llen eine eigenstĂ€ndige Analgesie durch NotSan entlang der Delegation der ĂLRD. Die SchmerzintensitĂ€t nach der NRS konnte von im Median 7 (Interquartilsabstand [IQR] 2) auf 3 (IQR 2, pâŻ<â0,001) gesenkt und in 96,9âŻ% ein aus Patientensicht tolerables Niveau erreicht werden. In 9,4âŻ% der FĂ€lle wurde ein Notarzt nachgefordert und in 5,0âŻ% eine ergĂ€nzende Analgesie verabreicht. Etwa jeder zehnte Patient erhielt Sauerstoff. Atemwegsinterventionen waren in wenigen EinzelfĂ€llen notwendig, eine Antagonisierung nur nach höheren als den delegierten Opiatdosen.
Schlussfolgerung
Eine vom ĂLRD delegierte und von NotSan eigenstĂ€ndig durchgefĂŒhrte Opiatgabe senkt das Schmerzniveau relevant. Wesentliche Hinweise auf eine PatientengefĂ€hrdung fanden sich nicht. Durch dieses Verfahren konnten in Bayern jĂ€hrlich geschĂ€tzt ca. 2500 NotarzteinsĂ€tze vermieden werden
The organizational embeddedness of social capital: a comparative case study of two voluntary organisations
Social capital is a popular, but contested concept. It draws attention to the way in which social relations and constructed forms of social organization can produce outcomes on individual and collective levels. However, it is often founded on individualistic, rational-choice models of human behavior that neglect its embeddedness. I explore the embeddedness of social capital through a comparative case study of two voluntary sport organizations in the UK. Through close analysis of in-depth interviews and longitudinal observation, I look at the processes of social capital development and at how socio-organizational context and identity shape these processes
