How to play the game of medical education: Sociocultural analyses of educational difficulties among medical residents.

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.

Early Assessment of Cost-effectiveness of Gastric Electrical Stimulation for Diabetic Nausea and Vomiting.

BACKGROUND/AIMS: Recurrent nausea and/or vomiting are common complications of diabetes mellitus. The conditions severely impact the quality of life of patients and often cause repeated admissions to hospital incurring significant healthcare costs. If standard treatment fails, gastric electrical stimulation (GES) may be offered in selected cases, as a minimally invasive, but expensive, therapeutic option. Our aims are to evaluate the clinical effect and the cost-utility of GES as a treatment for severe diabetic recurrent nausea and/or vomiting. METHODS: Among 33 diabetes patients implanted with GES because of recurrent nausea and/or vomiting, 30 were available for evaluation. The effect of treatment was assessed prospectively using symptom-diaries and the SF-36 questionnaires at baseline, after 6 and 12 months, and thereafter yearly. The number of days in hospital due to symptoms related to gastrointestinal dysfunction was calculated using hospital records 12 months prior to and 12 months after implantation. RESULTS: The surgical procedures were performed without mortality or major complications. Six months after surgery 78% of the respondents had at least 50% reduction in time with nausea and 48% had at least 50% reduction in days with vomiting. Symptom relief persisted at follow-up after at least 4 years. Quality adjusted life years improved after GES, which was cost-effective after 24 months. CONCLUSIONS: GES reduces symptoms and improves quality of life in diabetes patients with recurrent nausea and/or vomiting. The procedure is supposed as cost-effective over a 2-year time horizon.

Residents in difficulty: a mixed methods study on the prevalence, characteristics, and sociocultural challenges from the perspective of residency program directors.

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.

Acute differential effects of dietary protein quality on postprandial lipemia in obese non-diabetic subjects.

Non-fasting triglyceridemia is much closer associated to cardiovascular risk compared to fasting triglyceridemia. We hypothesized that there would be acute differential effects of four common dietary proteins (cod protein, whey isolate, gluten, and casein) on postprandial lipemia in obese non-diabetic subjects. To test the hypothesis we conducted a randomized, acute clinical intervention study with crossover design. We supplemented a fat rich mixed meal with one of four dietary proteins i.e. cod protein, whey protein, gluten or casein. Eleven obese non-diabetic subjects (age: 40-68, body mass index: 30.3-42.0 kg/m(2)) participated and blood samples were drawn in the 8-h postprandial period. Supplementation of a fat rich mixed meal with whey protein caused lower postprandial lipemia (P = .048) compared to supplementation with cod protein and gluten. This was primarily due to lower triglyceride concentration in the chylomicron rich fraction (P = .0293). Thus, we have demonstrated acute differential effects on postprandial metabolism of four dietary proteins supplemented to a fat rich mixed meal in obese non-diabetic subjects. Supplementation with whey protein caused lower postprandial lipemia compared to supplementation with cod and gluten. As postprandial lipemia is closely correlated to cardiovascular disease, long-term dietary supplementation with whey protein may prove beneficial in preventing cardiovascular disease in obese non-diabetic subjects.

Differential effects of dietary protein sources on postprandial low-grade inflammation after a single high fat meal in obese non-diabetic subjects.

BACKGROUND: Obesity is a state of chronic low-grade inflammation. Chronic low-grade inflammation is associated with the pathophysiology of both type-2 diabetes and atherosclerosis. Prevention or reduction of chronic low-grade inflammation may be advantageous in relation to obesity related co-morbidity. In this study we investigated the acute effect of dietary protein sources on postprandial low-grade inflammatory markers after a high-fat meal in obese non-diabetic subjects. METHODS: We conducted a randomized, acute clinical intervention study in a crossover design. We supplemented a fat rich mixed meal with one of four dietary proteins - cod protein, whey isolate, gluten or casein. 11 obese non-diabetic subjects (age: 40-68, BMI: 30.3-42.0 kg/m2) participated and blood samples were drawn in the 4 h postprandial period. Adiponectin was estimated by ELISA methods and cytokines were analyzed by multiplex assay. RESULTS: MCP-1 and CCL5/RANTES displayed significant postprandial dynamics. CCL5/RANTES initially increased after all meals, but overall CCL5/RANTES incremental area under the curve (iAUC) was significantly lower after the whey meal compared with the cod and casein meals (P = 0.0053). MCP-1 was initially suppressed after all protein meals. However, the iAUC was significantly higher after whey meal compared to the cod and gluten meals (P = 0.04). CONCLUSION: We have demonstrated acute differential effects on postprandial low grade inflammation of four dietary proteins in obese non-diabetic subjects. CCL5/RANTES initially increased after all meals but the smallest overall postprandial increase was observed after the whey meal. MCP-1 was initially suppressed after all 4 protein meals and the whey meal caused the smallest overall postprandial suppression. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT00863564.

Educational climate seems unrelated to leadership skills of clinical consultants responsible of postgraduate medical education in clinical departments.

BACKGROUND: The educational climate is crucial in postgraduate medical education. Although leaders are in the position to influence the educational climate, the relationship between leadership skills and educational climate is unknown. This study investigates the relationship between the educational climate in clinical departments and the leadership skills of clinical consultants responsible for education. METHODS: The study was a trans-sectional correlation study. The educational climate was investigated by a survey among all doctors (specialists and trainees) in the departments. Leadership skills of the consultants responsible for education were measured by multi-source feedback scores from heads of departments, peer consultants, and trainees. RESULTS: Doctors from 42 clinical departments representing 21 specialties participated. The response rate of the educational climate investigation was moderate 52% (420/811), Response rate was high in the multisource-feedback process 84.3% (420/498). The educational climate was scored quite high mean 3.9 (SD 0.3) on a five-point Likert scale. Likewise the leadership skills of the clinical consultants responsible for education were considered good, mean 5.4 (SD 0.6) on a seven-point Likert scale. There was no significant correlation between the scores concerning the educational climate and the scores on leadership skills, r = 0.17 (p = 0.29). CONCLUSIONS: This study found no relation between the educational climate and the leadership skills of the clinical consultants responsible for postgraduate medical education in clinical departments with the instruments used. Our results indicate that consultants responsible for education are in a weak position to influence the educational climate in the clinical department. Further studies are needed to explore, how heads of departments and other factors related to the clinical organisation could influence the educational climate.

Effects of different protein sources on plasminogen inhibitor-1 and factor VII coagulant activity added to a fat-rich meal in type 2 diabetes.

BACKGROUND: Exaggerated postprandial triglyceride concentration is believed to be atherogenic, and to influence the risk of thrombosis. Both elevated plasminogen inhibitor 1 (PAI-1) and increased factor VII coagulant activity (FVIIc) are potential important contributors to the increased risk of cardiovascular disease in type 2 diabetes. AIM: We aimed to investigate the effect of adding four different protein types (i.e. casein, whey, cod, and gluten) to a fat-rich meal on postprandial responses of PAI-1 and FVIIc in type 2 diabetic patients. METHODS: Twelve type 2 diabetic patients ingested four isocaloric test meals in random order. The test meals contained 100 g of butter and 45 g of carbohydrate in combination with 45 g of casein (Cas-meal), whey (Whe-meal), cod (Cod-meal), or gluten (Glu-meal), respectively. Plasma concentrations of PAI-1 and FVIIc were measured before meal, and at regular intervals for 8-h postprandially. RESULTS: The postprandial PAI-1 concentration decreased significantly by 49% to 56% in response to the four test meals. There were no significant differences between the outcomes from the four test-meals. The FVIIc levels decreased by 8% to 11% after the meals. Again, we observed no significant differences in outcomes between the four protein-enriched meals. CONCLUSIONS: The four proteins casein, whey, cod, and gluten, added to a fat-rich meal, all decreased the PAI-1 and FVIIc concentrations postprandially in type 2 diabetic subjects. However, postprandial levels of PAI-1 and FVIIc were not acutely influenced by the protein source.

Differential effects of protein quality on postprandial lipemia in response to a fat-rich meal in type 2 diabetes: comparison of whey, casein, gluten, and cod protein.

BACKGROUND: Enhanced and prolonged postprandial triglyceride responses involve increased cardiovascular disease risk in type 2 diabetes. Dietary fat and carbohydrates profoundly influence postprandial hypertriglyceridemia, whereas little information exists on the effect of proteins. OBJECTIVE: The objective was to compare the effects of the proteins casein, whey, cod, and gluten on postprandial lipid and incretin responses to a high-fat meal in persons with type 2 diabetes. DESIGN: A crossover study was conducted in 12 patients with type 2 diabetes. Blood samples were collected over 8 h after ingestion of a test meal containing 100 g butter and 45 g carbohydrate in combination with 45 g casein (Cas-meal), whey (Whe-meal), cod (Cod-meal), or gluten (Glu-meal). We measured plasma concentrations of triglycerides, retinyl palmitate (RP), free fatty acids, insulin, glucose, glucagon, glucagon-like peptide 1, and glucose-dependent insulinotropic peptide. RESULTS: The incremental area under the curve for triglyceride was significantly lower after the Whe-meal than after the other meals. The RP response was lower after the Whe-meal than after the Cas-meal and Cod-meal in the chylomicron-rich fraction and higher after the Whe-meal than after Cod- and Glu-meals in the chylomicron-poor fraction. Free fatty acids were most pronouncedly suppressed after the Whe-meal. The glucose response was lower after the Whe-meal than after the other meals, whereas no significant differences were found in insulin, glucagon, glucagon-like peptide 1, and glucose-dependent insulinotropic peptide responses. CONCLUSION: The data suggest that as a supplement to a fat-rich meal in patients with type 2 diabetes, whey protein seems to outperform other proteins in terms of postprandial lipemia improvement, possibly because of the formation of fewer chylomicrons or increased clearance of chylomicrons. The trial was registered at ClinicalTrials.gov as NCT00817973.

Bodyweight changes associated with antihyperglycaemic agents in type 2 diabetes mellitus.

The majority of patients with type 2 diabetes mellitus are overweight or obese at the time of diagnosis, and obesity is a recognised risk factor for type 2 diabetes and coronary heart disease (CHD). Conversely, weight loss has been shown to improve glycaemic control in patients with type 2 diabetes, as well as to lower the risk of CHD. The traditional pharmacotherapies for type 2 diabetes can further increase weight and this may undermine the benefits of improved glycaemic control. Furthermore, patients' desire to avoid weight gain may jeopardise compliance with treatment, thereby limiting treatment success and indirectly increasing the risk of long-term complications. This review evaluates the influences of established and emerging therapies on bodyweight in type 2 diabetes. Improvement in glycaemic control with insulin secretagogues has been associated with weight gain. On the other hand, biguanides such as metformin have been consistently shown to have a beneficial effect on weight; metformin appears to modestly reduce weight when used as a monotherapy. alpha-Glucosidase inhibitors are considered weight neutral; in fact, the results of some studies show that they cause reductions in weight. Thiazolidinediones (TZDs) are typically associated with weight gain and increased risk of oedema, while the impact of some TZDs, such as pioglitazone, on lipid homeostasis could be beneficial. Insulin, the most effective therapy when oral agents are ineffective, has always been linked to significant weight gain. Newly developed insulin analogues can lower the risk of hypoglycaemia compared with human insulin, but most have no advantage in terms of weight gain. The basal analogue insulin detemir, however, has been demonstrated to cause weight gain to a lesser extent than human insulin. The emerging treatments, such as glucagon-like peptide-1 agonists and the amylin analogue, pramlintide, seem able to decrease weight in patients with type 2 diabetes, whereas dipeptidyl peptidase-4 inhibitors seem to be weight neutral. In summary, while reduction of hyperglycaemia remains the foremost goal in the treatment of patients with type 2 diabetes, the avoidance of weight gain may be a clinically important secondary goal. This is already possible with careful selection of available therapies, while several emerging therapies promise to further extend the options available.

Can the Glycemic Index (GI) be used as a tool in the prevention and management of Type 2 diabetes?

The large increase in type 2 diabetes (T2DM), the considerable lifetime risk of diabetes and the loss of lifetime call for concerted action to prevent T2DM and its complications. Since diabetes is characterized by abnormal glucose metabolism, the question arises of whether a high intake of carbohydrates that are rapidly absorbed as glucose may increase the risk and worsen the course of T2DM. To quantify the impact of carbohydrates on blood glucose the glycemic index (GI) and the glycemic load (GL) have been applied. The GI of a food is a method of ranking carbohydrate rich foods according to their glycemic responses. GI is defined as the incremental area under the blood glucose curve of 50g carbohydrate of a test food expressed as a percentage of the area of the response to an equivalent amount of a reference food (glucose or white bread). In relation to GI/GL and prevention of T2DM there is insufficient information from observational studies to determine whether a positive association exists or not. Only randomized controlled clinical intervention studies will be able to provide the final answer. From meta-analyses of randomised controlled clinical trials comparing low and high GI diets in the treatment of diabetes it has been found that low GI diets improve the glycemic control. Labeling of foods with GI would be helpful for persons with diabetes, but the usefulness for healthy subjects remains to be clarified. At present it seems premature to introduce GI labeling for the entire population.

Long-term parathyroid- and c-cell function after radioiodine for benign thyroid diseases.

The study examined static and dynamic parathyroid hormone and calcitonin secretion after radioiodine, and was a retrospective study of patients having received radioiodine for benign conditions 8-12 years earlier. In one group of patients parathyroid hormone and calcium were measured as single blood tests, in a second group of patients parathyroid hormone and calcitonin secretion capacity were measured during a hypocalcaemic citrate-clamp and a hypercalcaemic stimulation test. Baseline calcium and parathyroid hormone were normal within expected ranges 8-12 years after radioiodine. Stimulated parathyroid hormone or calcitonin secretion did not differ from an age- and gender-matched control group. Radioiodine in doses used for benign thyroid diseases appears safe with regard to parathyroid hormone and calcitonin secretion.
