RESUMO

BACKGROUND: Despite the rising incidence of melanoma, medical students have progressively fewer opportunities to encounter patients with this important condition. Curricula tend to attach the greatest value to intellectual forms of learning. However, compared with intellectual learning, experiential learning affords students deep insights about a condition. Doctors who experience ill health are more empathic towards patients. However, opportunities to learn about cancer experientially are limited. Temporary transfer tattoos can simulate the ill health associated with melanoma. We reasoned that if doctors who have been sick are more empathic temporarily 'having' melanoma might have a similar effect. OBJECTIVES: To explore the impact of wearing a melanoma tattoo on medical students' understanding of patienthood and attitudes towards patients with melanoma. METHODS: Ten fourth-year medical students were recruited to a simulation. They wore a melanoma tattoo for 24 h and listened to a patient's account of receiving their diagnosis. Data were captured using audio diaries and face-to-face interviews, transcribed and analysed phenomenologically using the template analysis method. RESULTS: There were four themes: (i) melanoma simulation: opening up new experiences; (ii) drawing upon past experiences; (iii) a transformative introduction to patienthood; (iv) doctors in the making: seeing cancer patients in a new light. CONCLUSIONS: By means of a novel simulation, medical students were introduced to lived experiences of having a melanoma. Such an inexpensive simulation can prompt students to reflect critically on the empathetic care of such patients in the future.

RESUMO

There is widespread acceptance that clinical educators should be trained to teach, but faculty development for clinicians is undermined by poor attendance and inadequate learning transfer. As a result there has been growing interest in situating teacher development initiatives in clinical workplaces. The relationship between becoming a teacher and clinical workplace contexts is under theorised. In response, this qualitative research set out to explore how clinicians become teachers in relation to clinical communities and institutions. Using communities of practice (CoP) as a conceptual framework this research employed the sensitising concepts of regimes of competence and vertical (managerial) and horizontal (professional) planes of accountability to elucidate structural influences on teacher development. Fourteen hospital physicians completed developmental timelines and underwent semi-structured interviews, exploring their development as teachers. Despite having very different developmental pathways, participants' descriptions of their teacher identities and practice that were remarkably congruent. Two types of CoP occupied the horizontal plane of accountability i.e. clinical teams (Firms) and communities of junior doctors (Fraternities). Participants reproduced teacher identities and practice that were congruent with CoPs' regimes of competence in order to gain recognition and legitimacy. Participants also constructed their teacher identities in relation to institutions in the vertical plane of accountability (i.e. hospitals and medical schools). Institutions that valued teaching supported the development of teacher identities along institutionally defined lines. Where teaching was less valued, clinicians adapted their teacher identities and practices to suit institutional norms. Becoming a clinical educator entails continually negotiating one's identity and practice between two potentially conflicting planes of accountability. Clinical CoPs are largely conservative and reproductive of teaching practice whereas accountability to institutions is potentially disruptive of teacher identity and practice.

RESUMO

Work based learning and teaching in health care settings are complex and dynamic. Sociocultural theory addresses this complexity by focusing on interaction between learners, teachers, and their environment as learners develop their professional identity. Although social interaction between doctors and students plays a crucial role in this developmental process, socio-cultural research from the perspective of doctors is scarce. We performed discourse analysis on seven general practitioners' audio diaries during a 10-week general practice clerkship to study how they gave shape to their interaction with their students. Examination of 61 diary-entries revealed trajectories of developing relationships. These trajectories were initiated by the way respondents established a point of departure, based on their first impression of the students. It continued through the development of dialogue with their student and through conceptualizations of good medical practice. Such conceptualizations about what was normal in medical and educational practice enabled respondents to recognize qualities in the student and to indirectly determine students' desired learning trajectory. Towards the end, discursive turns in respondents' narratives signaled development within the relationship. This became evident in division of roles and positions in the context of daily practice. Although respondents held power in the relationships, we found that their actions depended strongly on what the students afforded them socially. Our findings address a gap in literature and could further inform theory and practice, for example by finding out how to foster constructive dialogue between doctors and students, or by exploring different discourses among learners and teachers in other contexts.

RESUMO

INTRODUCTION: Disparity exists between the growing consensus about the positive effects of reflection on performance and the scarcity of empirical evidence demonstrating this effect. Portfolios are considered a useful instrument to assess and supervise competence-based education and to stimulate reflection. The present study describes the introduction of a portfolio in a social dentistry and oral health promotion course and investigates student reflection as a predictor for the acquisition of the other competences in the course. METHODS: Fourth year undergraduate dental students (n = 110) in the course 'Society and Health' between 2008 and 2011 collected evidence in their portfolios, demonstrating the acquisition of five competences: the ability to (1) assess the oral health profile of a target group; (2) integrate theoretical models in health promotion; (3) search for and apply scientific evidence; (4) work trans-, multi- and/or trans-disciplinarily; (5) reflect on personal development. Linear regression analysis was used to investigate the predictive value of reflection on the other course related competences. RESULTS: Reflection scores proved to significantly predict other course-related competences, when analysing all students between 2008 and 2011 and for each year separately, explaining between 10.7% and 25.5% of the variance in the other competences. CONCLUSION: Undergraduate dental students' competences related to social dentistry and oral health promotion were significantly predicted by the reflection scores obtained in a portfolio-based context. In line with the growing consensus about the benefits of reflection for dental students and professionals, results suggest the value to further develop the integration of reflection in dental education and practice.

RESUMO

Avoidant attachment has been found to impair attendance at appointments and treatment adherence of patients with diabetes, but the role of staff-patient relationships has not been explored. This study investigates whether attachment influences the quality of alliance between patients with diabetes and healthcare professionals. Patient avoidance was significantly associated with difficulties in therapeutic alliance. Further research is required to establish whether therapeutic alliance, underpinned by attachment, influences treatment adherence and to investigate ways of promoting collaboration.

RESUMO

REVIEW DATE: Review period January 1992-December 2001. Final analysis July 2004-January 2005. BACKGROUND AND REVIEW CONTEXT: There has been no rigorous systematic review of the outcomes of early exposure to clinical and community settings in medical education. OBJECTIVES OF REVIEW: Identify published empirical evidence of the effects of early experience in medical education, analyse it, and synthesize conclusions from it. Identify the strengths and limitations of the research effort to date, and identify objectives for future research. SEARCH STRATEGY: Ovid search of: BEI, ERIC, Medline, CINAHL and EMBASE Additional electronic searches of: Psychinfo, Timelit, EBM reviews, SIGLE, and the Cochrane databases. Hand-searches of:Medical Education, Medical Teacher, Academic Medicine, Teaching and Learning in Medicine, Advances in Health Sciences Education, Journal of Educational Psychology. EXPERIENCE: Authentic (real as opposed to simulated) human contact in a social or clinical context that enhances learning of health, illness and/or disease, and the role of the health professional. Early: What would traditionally have been regarded as the preclinical phase, usually the first 2 years. Inclusions: All empirical studies (verifiable, observational data) of early experience in the basic education of health professionals, whatever their design or methodology, including papers not in English. Evidence from other health care professions that could be applied to medicine was included. EXCLUSIONS: Not empirical; not early; post-basic; simulated rather than 'authentic' experience. DATA COLLECTION: Careful validation of selection processes. Coding by two reviewers onto an extensively modified version of the standard BEME coding sheet. Accumulation into an Access database. Secondary coding and synthesis of an interpretation. HEADLINE RESULTS: A total of 73 studies met the selection criteria and yielded 277 educational outcomes; 116 of those outcomes (from 38 studies) were rated strong and important enough to include in a narrative synthesis of results; 76% of those outcomes were from descriptive studies and 24% from comparative studies. Early experience motivated and satisfied students of the health professions and helped them acclimatize to clinical environments, develop professionally, interact with patients with more confidence and less stress, develop self-reflection and appraisal skill, and develop a professional identity. It strengthened their learning and made it more real and relevant to clinical practice. It helped students learn about the structure and function of the healthcare system, and about preventive care and the role of health professionals. It supported the learning of both biomedical and behavioural/social sciences and helped students acquire communication and basic clinical skills. There were outcomes for beneficiaries other than students, including teachers, patients, populations, organizations and specialties. Early experience increased recruitment to primary care/rural medical practice, though mainly in US studies which introduced it for that specific purpose as part of a complex intervention. CONCLUSIONS: Early experience helps medical students socialize to their chosen profession. It helps them acquire a range of subject matter and makes their learning more real and relevant. It has potential benefits for other stakeholders, notably teachers and patients. It can influence career choices.

RESUMO

There is heterogeneity within insulin-dependent diabetes mellitus (IDDM), and it has been suggested that the presence of the HLA-DR specificities DR3 and DR4 define two subsets of IDDM with clear differences in their immune response to therapeutic insulin. To test this hypothesis, we have prospectively studies the development of insulin binding antibody (IBA) in 54 subjects with newly diagnosed, classical childhood IDDM, determined seven binding constants of their IBA, and measured the presence or absence of pancreatic polypeptide-binding antibodies after 1 yr of therapy with insulin. There were no relationships between insulin and pancreatic polypeptide antibodies and the DR3 or DR4 specificities whether these specificities were tested for alone or in combination, comparing the presence and absence of DR3 and DR4 and comparing DR3 with DR4, except that of the 33% of all subjects who developed antibodies binding pancreatic polypeptide by 1 yr, none possessed the DR3 specificity alone (P = 0.018). Thus, the hypothesis that the HLA-DR3 and -DR4 specificities are major determinants of IBA formation and, therefore, define important subsets of childhood IDDM in terms of immune response to therapeutic insulin is not substantiated by this study.

RESUMO

HLA types and blood glucose control were investigated in 127 insulin-dependent diabetics with different grades of severity of retinopathy. The means of all afternoon clinic blood glucose levels from the diagnosis of diabetes were 9.9 +/- 2.1 mmol/L for patients with no retinopathy, 11.8 +/- 2.1 mmol/L for patients with background retinopathy, and 12.4 +/- 2.1 mmol/L for patients with proliferative retinopathy (P less than 0.0001). HLA-DR4 was present in 61 of 87 patients (70%) with background or proliferative retinopathy and 21 of 39 (54%) with no retinopathy. The frequency of HLA-DR4 was lowest in patients with no retinopathy despite "poor control" (mean blood glucose greater than or equal to 11.5 mmol/L) and highest in those who had developed retinopathy despite "good control;" the frequencies of HLA-DR2 showed the reverse pattern. Mantel-Haenszel tests were used to calculate the odds ratios for the presence of retinopathy associated with "poor control" and with HLA-DR4, since each modified the effect of the other. The odds ratio for retinopathy associated with "poor control" was 6.7 (P less than 0.0001). The odds ratio with HLA-DR4 was 3.7 (P less than 0.005). When both risk factors were present, the odds ratio increased to 33.3 (P less than 0.0001). Genetically determined factors appear to influence susceptibility to retinopathy in insulin-dependent diabetics.

RESUMO

OBJECTIVE: To test the efficacy and tolerability of metformin. RESEARCH DESIGN AND METHODS: An 8-mo double-blind placebo-controlled parallel-group trial was performed at University hospital diabetic clinics on 60 patients with non-insulin-dependent diabetes mellitus (NIDDM) treated by diet alone. Metformin was administered and built up to a maximum dosage of 1 g three times daily. RESULTS: Mean HbA1 fell from 11.7 +/- 0.4 to 10.3 +/- 0.4% (means +/- SE) on metformin but rose from 11.8 +/- 0.4 to 13.3 +/- 0.4% on placebo (P less than 0.001). Final mean fasting blood glucose was 5.1 mM lower with metformin than placebo (P less than 0.001). No other biochemical variable differed significantly, and weight did not change. A favorable glycemic response was not restricted to the obese. The mean final dosage of metformin was 1.7 +/- 0.1 g and was well tolerated. CONCLUSIONS: Metformin achieved a 23% lower mean HbA1 than placebo without weight gain or significant unwanted effects.

RESUMO

OBJECTIVE: To evaluate the performance of a hand-held ketone sensor that is able to measure blood beta-hydroxybutyrate (beta-HBA) concentrations within 30 s in patients with diabetic ketoacidosis (DKA) and patients who attend a weight management clinic. RESEARCH DESIGN AND METHODS: Two groups of patients were studied: 19 patients admitted with DKA and 156 patients attending a weight management clinic. Paired capillary and venous whole blood samples were measured using the ketone sensor and also using an enzymatic laboratory reference method. RESULTS: The ketone sensor accurately measured beta-HBA concentrations in patients with DKA (limits of agreement -0.9 to + 1.0 mmol/l) or starvation-induced ketonemia (limits of agreement -0.5 to +0.5 mmol/l). CONCLUSIONS: This ketone sensor accurately measures whole blood beta-HBA concentrations within 30 s.

RESUMO

OBJECTIVE: To measure well-being and treatment satisfaction and their correlates in older people with diabetes. RESEARCH DESIGN AND METHODS: A postal survey was conducted of 1,000 diabetic patients aged > or = 60 years, representing 56% of the resident older diabetic population in an inner-city health district with a largely indigenous population of 230,000 people and a widely varied socioeconomic mix. Well-being and treatment satisfaction were measured with diabetes-specific instruments and correlated with patient data held in a central register. RESULTS: There was an 81% response. The general well-being scores (median [interquartile range]) for patients on diet alone, tablets, and insulin were 54 (44-60), 53 (42-61), and 48 (35-56) (P < 0.001 comparing insulin with diet and tablets) compared with a scale maximum of 66. Treatment satisfaction scores were 35 (31-36), 35 (32-36), and 34 (30-36) (P < 0.001 comparing insulin with diet and tablets), scale maximum 36. Mean HbA1c concentrations were 5.0 +/- 1.4% (for patients on diet alone), 5.8 +/- 1.6% (tablets), and 6.6 +/- 1.7% (insulin) (P < 0.001 for each difference). Neither well-being nor treatment satisfaction correlated with HbA1c. Insulin-treated patients were younger and had been diabetic longer than non-insulin-treated patients; their well-being remained slightly, but significantly, lower when adjusted for age, sex, BMI, and diabetes duration, but treatment satisfaction was no longer significantly different. Women had lower well-being than men. CONCLUSIONS: It has proved possible to measure well-being and treatment satisfaction in a large community-based samples of older people with diabetes. At the level of glycemic control in this population, neither parameter correlated with HbA1c. The lower well-being in insulin-treated patients remained significant in multivariate analysis.

RESUMO

BACKGROUND: In 2006, the Buttimer report highlighted the paucity of demographic data on those applying for and entering postgraduate medical education and training (PGMET) in Ireland. Today, concerns that there is an "exodus" of graduates of Irish medical schools are at the forefront of national discussion, however, published data on PGMET remains inadequate. AIMS: The objectives of this study were to collate existing data relating to trainees and training programmes at three stages of training and to examine the career plans of junior trainees. METHODS: Data from application forms for training programmes, commencing July 2012, under the Royal College of Physicians of Ireland (n = 870), were integrated with data from other existing sources. Candidates entering basic specialist training were surveyed with regard to career plans. Descriptive and comparative analysis was performed in SPSS version 18. RESULTS: Graduates of Irish medical schools made up over 70 % of appointees. Over 80 % of BST trainees aspired to work as consultants in Ireland, but 92.5 % planned to spend time working abroad (response rate 77 %). Decisions to leave the Irish system were linked to lifestyle, but also to failure to be appointed to higher specialist training. Significant numbers of trainees return to Ireland after a period abroad. CONCLUSIONS: The trainee "exodus" is more complex than is often portrayed. The desire to spend time working outside Ireland must be accounted for in workforce planning and configuration of training programmes. Expansion of HST is a potential solution to reduce the numbers of graduates leaving Ireland post-BST.

RESUMO

The regulation and secretion of the ACTH precursors POMC and pro-ACTH were assessed directly using a 2-site immunoradiometric assay in six patients with pituitary macroadenomas (> or = 1.2 cm in diameter) and 27 patients with Cushing's disease due to a microadenoma. ACTH precursor levels were elevated in patients with macroadenomas (150-3690 pmol/L; normal range, < 5-40 pmol/L) and significantly higher than those in microadenoma patients (median, 29 pmol/L; range, 9-104 pmol/L; P < 0.001). Patients with macroadenomas also had increased ACTH precursor/ACTH ratios (15-181:1) compared with microadenoma patients (median, 5:1, range, 0.7-18.5:1; P < 0.001). ACTH precursors were unresponsive to high dose dexamethasone in patients with macroadenomas, whereas ACTH and cortisol responses varied. After CRH administration, ACTH precursors were unchanged, whereas cortisol increased significantly, suggesting the release of biologically active ACTH. This study clearly demonstrates reduced processing of POMC to ACTH in large pituitary tumors, a characteristic usually associated with tumors causing the ectopic ACTH syndrome, and provides evidence for differential regulation of ACTH precursors and ACTH by glucocorticoid and CRH. Variation in the clinical symptoms of patients with corticotroph macroadenomas may be attributable to differences in biological potency between the ACTH precursors and ACTH.

RESUMO

To investigate whether glucose has an effect on the pancreatic A cell independent of intraislet or paracrine B cell mediation, we have tested the ability of changes in plasma glucose (PG) level to influence the acute glucagon response (AGR) to 5 g of intravenous arginine in 8 C-peptide negative insulin dependent diabetics (IDD). Insulin was infused (1 mU/kg/min) for a 90 min basal period during which PG levels were maintained constant by the glucose clamp technique. Basal AGR was then determined. In 4 of the diabetics, the PG level was subsequently lowered to a new steady state and, in 2 diabetics, PG level was raised. In 2 additional IDDs, two manipulations in PG level were carried out (PG ranges 51-390 mg/dl). The same insulin infusion was continued throughout. The acute glucagon response to arginine was determined at each PG level. The ability of unit changes in PG to influence (modulate) the AGR (MdIRG) was calculated as the difference in AGRs divided by the PG difference. MdIRG was consistent between diabetics (means +/- SEM = 2.1 +/- 0.2) and was independent of both direction and magnitude of the PG change. Thus, in vivo, in man, glucose has an effect on the pancreatic A cell which is independent of intraislet B cell influences.

RESUMO

Bartter's syndrome is a well described but uncommon disease characterized by hypokalaemia and hyperplasia of the juxtaglomerular apparatus of the kidney. It may present in infancy with failure to thrive and muscle weakness; it commonly causes short stature. Lesions at different sites within the renal tubule have been proposed as the cause of the syndrome. However, the biochemical abnormalities in many cases can be explained by defective reabsorption of chloride in the ascending loop of Henle, with loss of sodium and water and a secondary increase in renin and aldosterone concentrations. Less severe cases have been described which present in adolescence and have tetany as a prominent feature. Primary renal loss of magnesium associated with potassium wasting has been described in such cases and it has been suggested that these can be distinguished from classical Bartter's syndrome by hypocalciuria. This less well characterized disease has been named Welt, Gitelman-Welt or Gitelman syndrome and may include deficient tubular reabsorption of chloride, but the sites of magnesium and potassium loss in the kidney are uncertain. We describe a patient with this syndrome who presented with short stature, delayed puberty and tetany and responded well to magnesium replacement.

RESUMO

A woman with hirsutism but otherwise symptom-free was found to have a raised serum prolactin and a pituitary microadenoma. The hyperprolactinaemia persisted despite bromocriptine therapy and subsequent pituitary surgery, which yielded a non-functioning adenoma. After a further 15 years with persistent hyperprolactinaemia but no symptoms, macroprolactinaemia was diagnosed. Such cases might account for part of the failure rate of pituitary microsurgery for prolactinoma. Testing for macroprolactinaemia is advisable in a woman with hyperprolactinaemia, especially if her ovulatory cycle is normal. Two other cases are reported in which macroprolactinaemia was associated with menstrual disturbances and other hormonal effects: in these, treatment with dopamine agonists suppressed the hyperprolactinaemia and restored normal menstrual cycles.

RESUMO

The University of Manchester Medical School has adopted problem-based learning as its main educational method, with a change of emphasis from a biomedical to a biopsychosocial approach. The training of junior medical students in clinical interviewing is intended to reinforce and develop their interpersonal skills. We measured the impact of this new curriculum by assessing two intakes of students covering the period before and after its introduction; a third intake was later added to examine the effect of further curriculum adjustments. 86 students, randomly selected, were videorecorded conducting diagnostic interviews with standardized patients 10 weeks after they had started to learn clinical interviewing. Two instruments were developed--a 23-item communication skills scale and a 13-item information-gathering scale and both showed acceptable inter-rater and test-retest reliability. Communication skills did not differ between years. The total score for information-gathering fell by 13% (95% confidence interval -20 to -6%, P < 0.001) in the first year after introduction of the new educational approach but returned to baseline the following year after further modification of the course. Although the new approach yielded no measurable improvement in the process of communication, assessment 10 weeks after the start of interview training may be too early to permit definitive conclusions. We conclude that it is possible to change to a more patient-centred emphasis in teaching medical interviewing. Some initial loss of information content was rectified by adjustment of the course. Our unfavourable early experience highlights the need to evaluate educational change.

RESUMO

BACKGROUND: Postgraduate medical training in Ireland has been compared unfavourably with training abroad and blamed for an "exodus" of graduates of Irish medical schools. Exploration of features of a good training environment and development of tools to measure it have been the focus of much published research. There have been no Irish studies examining training environment using such validated tools. AIM: The aim of this study was to use a validated tool, to examine the expectations and experience of training, amongst those training under the Royal College of Physicians of Ireland (RCPI). METHOD: The Dutch Residency Education Climate Test (D-RECT) is a 50 item tool to measure postgraduate learning environments. D-RECT was sent to all new entrants to RCPI training programmes in July 2012 (n = 527) and completed in regard to expectations of training (response rate 80.6 %). In March 2013, D-RECT was sent to all RCPI trainees (n = 1,246) to complete in relation to the post held on 1 March (response rate 32.6 %). Data were analysed in SPSS version 18. RESULTS: Experience fell short of expectations for basic specialist training, however, scores for experience rose with greater seniority to match expectations. Positive aspects were teamwork, consultant willingness to discuss patients and respectful treatment of trainees. Areas of weakness were provision of feedback and time to learn new skills. CONCLUSION: Measurement of learning environment at a national level using a quantitative tool provides useful information for quality assurance and improvement of training.
