RESUMO

OBJECTIVE: Intravenous iron-a common treatment for anaemia and iron deficiency due to inflammatory bowel disease (IBD)-can cause hypophosphataemia. This trial compared the incidence of hypophosphataemia after treatment with ferric carboxymaltose (FCM) or ferric derisomaltose (FDI). DESIGN: This randomised, double-blind, clinical trial was conducted at 20 outpatient hospital clinics in Europe (Austria, Denmark, Germany, Sweden, UK). Adults with IBD and iron deficiency anaemia (IDA) were randomised 1:1 to receive FCM or FDI at baseline and at Day 35 using identical haemoglobin- and weight-based dosing regimens. The primary outcome was the incidence of hypophosphataemia (serum phosphate <2.0 mg/dL) at any time from baseline to Day 35 in the safety analysis set (all patients who received ≥1 dose of study drug). Markers of mineral and bone homeostasis, and patient-reported fatigue scores, were measured. RESULTS: A total of 156 patients were screened; 97 (49 FDI, 48 FCM) were included and treated. Incident hypophosphataemia occurred in 8.3% (4/48) FDI-treated patients and in 51.0% (25/49) FCM-treated patients (adjusted risk difference: -42.8% (95% CI -57.1% to -24.6%) p<0.0001). Both iron formulations corrected IDA. Patient-reported fatigue scores improved in both groups, but more slowly and to a lesser extent with FCM than FDI; slower improvement in fatigue was associated with greater decrease in phosphate concentration. CONCLUSION: Despite comparably effective treatment of IDA, FCM caused a significantly higher rate of hypophosphataemia than FDI. Further studies are needed to address the longer-term clinical consequences of hypophosphataemia and to investigate mechanisms underpinning the differential effects of FCM and FDI on patient-reported fatigue.

RESUMO

BACKGROUND & AIMS: Industrial foods have been associated with increased risks of several chronic conditions. We investigated the relationship between the degree of food processing and risks of Crohn's disease (CD) and ulcerative colitis (UC) in the European Prospective Investigation into Cancer and Nutrition cohort. METHODS: Analyses included 413,590 participants (68.6% women; mean baseline age, 51.7 y) from 8 European countries. Dietary data were collected at baseline from validated country-specific dietary questionnaires. Associations between proportions of unprocessed/minimally processed and ultraprocessed food intake and CD and UC risks were estimated using Cox models to obtain hazard ratios (HRs) and 95% CIs. Models were stratified by center, age, and sex, and adjusted for smoking status, body mass index, physical activity, energy intake, educational level, and alcohol consumption. RESULTS: During a mean follow-up period of 13.2 years, 179 incident cases of CD and 431 incident cases of UC were identified. The risk of CD was lower in people consuming high proportions of unprocessed/minimally processed foods (adjusted HR for the highest vs lowest quartile: 0.57; 95% CI, 0.35-0.93; P trend < .01), particularly fruits and vegetables (adjusted HRs, 0.54; 95% CI, 0.34-0.87 and 0.55; 95% CI, 0.34-0.91, respectively). There was no association between unprocessed/minimally processed food intake and the risk of UC. No association was detected between ultraprocessed food consumption and CD or UC risks. CONCLUSIONS: In the European Prospective Investigation into Cancer and Nutrition cohort, consumption of unprocessed/minimally processed foods was associated with a lower risk of CD. No association between UC risk and food processing was found.

RESUMO

Objective: Randomized controlled trials have shown the effectiveness of Adalimumab in ulcerative colitis. However, real-life data is scarce. We aimed to assess the effectiveness and predictive factors of effectiveness in a large Swedish cohort.Methods: Retrospective capture of data from local registries at five Swedish IBD centers. Clinical response and remission rates were assessed at three months after starting adalimumab treatment and patients were followed until colectomy or need for another biological. Bio-naive patients were compared to bio experienced patients. Factors associated with short term responses were assessed using logistic regression model. Failure on drug was assessed using a Cox proportional hazards regression model.Results: 118 patients (59 males, 59 females) with median age 34.4 years (IQR 27.0-51.4) were included. Median disease duration was 4.3 years (IQR 2.0-9.0) and follow-up 1.27 years (IQR 0.33-4.1). A clinical corticosteroid-free remission was achieved by 38/118 (32.2%) and response by 91/118 (77%) after three months. CRP >3 mg/l at baseline was predictive of short-term failure to reach corticosteroid-free remission. Factors associated with survival on the drug were male gender, CRP <3 mg/l and absence of primary sclerosing cholangitis. Patients >42 years of age at diagnosis were more likely to respond to adalimumab and remain on treatment compared to patients <20 years.Conclusions: An elevated CRP-level, primary sclerosing cholangitis and female gender were predictors of treatment failure. In contrast older age at diagnosis was a predictor of short-term clinical response and drug survival. Prior infliximab failure, regardless of cause, did not influence the outcome of adalimumab treatment.

RESUMO

Background and aims: Liver cirrhosis is a risk factor for hepatocellular carcinoma (HCC). While the HCC risk is thought to be highest in hepatitis B and hepatitis C, the risk in other cirrhosis etiologies is not fully established. Therefore, we aimed to study the risk and outcome of HCC in alcoholic cirrhosis compared to cirrhosis of other etiologies, in Sweden. Material and methods: We used population-based medical registries to identify patients diagnosed with cirrhosis in the Scania region in southern Sweden between 2001 and 2010. Medical records were reviewed to identify all HCC cases and to register clinical parameters. All patients were followed until death, emigration or December 2017. Results: The cohort comprised 1317 patients with cirrhosis. A total of 200 patient developed HCC, including 75 with prevalent HCC. The annual incidence of HCC after six months was 1.5% in alcoholic cirrhosis and 4.7% in hepatitis C cirrhosis. In alcoholic cirrhosis, 40 patients were diagnosed with HCC during follow-up, of which 15 patients fulfilled the Milan criteria and 10 received treatment, curative or palliative. The overall median survival after HCC diagnosis was 7.7 months, with 4.5, 11 and 9.3 months, in cirrhosis due to alcohol, hepatitis C or remaining causes, respectively. Conclusion: We find an annual incidence of HCC in alcoholic cirrhosis of 1.5% indicating need for surveillance in these patients. Survival after HCC diagnosis was worst in alcoholic cirrhosis due to more advanced stage at diagnosis with few patients eligible for treatment.

RESUMO

Background and aim: Progression to fibrosis in non-alcoholic fatty liver disease (NAFLD) is associated with an increased risk of liver-related events, overall mortality and possibly metabolic comorbidities. Our aim was to determine if non-invasive fibrosis scoring systems can predict the future risk of diabetes mellitus, cardiovascular disease (CVD), chronic kidney disease (CKD), liver-related events and overall mortality. Methods: Patients with biopsy-proven NAFLD 1978 to 2006 were identified from a computerised register in Malmö, Sweden. Medical records were scrutinised in detail to collect data from inclusion to endpoint (death or end of 2016). Non-invasive fibrosis scoring systems (FIB-4-index, NAFLD fibrosis score (NFS), APRI and BARD score) were calculated and the scores classified into three risk categories (low, intermediate and high risk for advanced fibrosis). Chronic kidney disease was evaluated using the CKD-EPI equation. Results: One hundred and forty-four patients with biopsy-proven NAFLD were included, with a mean age of 53.2 years and a mean follow-up time of 18.8 years. At inclusion, 18% had advanced fibrosis. NFS was the only score that could predict the future risk of all included outcomes with fairly good accuracy (Area-under-ROC curve). Multivariate-adjusted hazard ratios revealed that both the intermediate and high-risk category of FIB-4-index and NFS could significantly predict metabolic outcomes. All four scoring systems significantly predicted overall mortality in the high-risk category. Conclusions: Non-invasive fibrosis scoring systems, especially NFS and FIB-4-index, can be used to identify patients at risk of future liver-related events, overall mortality, metabolic comorbidities and CKD.

RESUMO

OBJECTIVES: Liver cirrhosis is characterized by a silent phase until decompensation, which is defined by onset of ascites, variceal bleeding, or encephalopathy. Although it is presumed that the survival of decompensated patients is the same regardless of when decompensation occurs, data to support this are scarce. We aimed to study the impact of time of decompensation on the clinical course and survival of patients with cirrhosis in a large population-based cohort. MATERIALS AND METHODS: We used medical registries to define a 10-year cohort of 1317 patients with incident liver cirrhosis in the Scania region of Sweden. Medical records were reviewed. Patients were followed until December 2011, and for death or transplantation until December 2014. RESULTS: In the cohort, 629 patients were decompensated at diagnosis, of which 505 had ascites and 44 variceal bleeding only. During follow-up, 228 patients developed ascites and 39 variceal bleeding as first complication. Patients with ascites as first complication showed worse survival than patients who had ascites at diagnosis. (5-year survival 33% vs. 15%, HR 1.60 (95% CI 1.34-1.90)). This difference persisted after adjustment for confounders, including hepatocellular cancer (HR 1.38 (95% CI 1.15-1.67)). Worse survival was also seen when bleeding from varices occurred during follow-up rather than at diagnosis. CONCLUSIONS: Our results provide evidence for an association between transplantation-free survival after decompensation and the time of decompensation in liver cirrhosis, with worse survival when decompensation occurs during follow-up, thus challenging the generally held, view that the survival after decompensation is independent of when decompensation occurs.

RESUMO

INTRODUCTION: Autoimmune hepatitis (AIH) is a liver disease that primarily affects women. Many become ill during childbearing age, and medication can be lifelong. Few studies exist on pregnancy outcome in women with AIH. Objectives The aim was to assess the outcome of women with AIH and their children during pregnancy and postpartum. MATERIALS AND METHODS: Sixty-four women from a well-characterised cohort with AIH filled out a questionnaire with information about their disease, miscarriage/abortion, pregnancies and potential birth defects in 2012. In 2004, 106 women answered the same questionnaire and their results were analysed along with the new questionnaires. RESULTS: One hundred and thirty-eight women have completed the questionnaire and 100 children have been born by 58 women. Fifty-seven women (41%) had cirrhosis. In 84% of the pregnancies, the AIH was stable or milder, 32% had an increase in activity postpartum. The proportion of preterm births (before week 38) was 22%, caesarean sections 17%, malformations 3%, and two children died. Twenty-three women with cirrhosis had children after diagnosis of cirrhosis but without more complications than for non-cirrhotic mothers. However, they did have a higher prevalence of caesarean sections. CONCLUSION: Pregnancy and childbirth in AIH appear to be safe for both child and mother, even in women with compensated liver cirrhosis.

RESUMO

OBJECTIVE: Iron isomaltoside (Monofer(®)) is a high-dose intravenous iron preparation with good tolerability and efficacy in inflammatory bowel disease (IBD) patients with iron deficiency anaemia (IDA). This trial evaluates the safety and efficacy, including effect on intact fibroblast growth factor 23 (iFGF23) of a high single dose and cumulative doses of iron isomaltoside in IBD patients with IDA. MATERIALS AND METHODS: The trial was a prospective, open-label, multi-centre trial conducted in IBD patients with IDA. Based upon haemoglobin (Hb) levels at baseline and weight, the patients received 1500, 2000, 2500 or 3000 mg of iron isomaltoside infused in single doses up to 2000 mg. The outcome measurements included adverse drug reactions (ADRs) and changes in haematology and biochemistry parameters. RESULTS: Twenty-one IBD patients with IDA were enrolled, receiving 1500 (seven patients), 2000 (eight patients), 2500 mg (four patients) or 3000 (two patients) mg of iron. No serious ADRs were observed. Four patients experienced nine mild to moderate ADRs (hypersensitivity, pyrexia, vomiting, constipation, abdominal pain, dyspepsia (two events) and eye allergy (two events)). In total, 15 (75%) patients had an increase in Hb of ≥2.0 g/dL during the trial, with normalisation of ferritin. No changes in iFGF23 or clinically significant hypophosphataemia were found. CONCLUSION: Rapid infusions of high-dose iron isomaltoside, administered as single doses up to 2000 mg and cumulative doses up to 3000 mg, were without safety concerns and were efficacious in increasing Hb levels in IBD patients. Iron isomaltoside did not induce profound phosphate wasting via increased iFGF23 levels.

RESUMO

OBJECTIVES: Cirrhosis is a well-known risk factor for hepatocellular cancer, but the true risk in autoimmune hepatitis (AIH) is scarcely studied. Other cancers may arise after prolonged use of immune-modulating drugs. The aim of this study was to investigate the cancer risk in a large cohort of AIH patients. MATERIAL AND METHODS: Six hundred and thirty-four Swedish patients in a well-defined cohort were matched to the Cause of Death Registry and the Cancer Registry. Standard incidence ratios were calculated by relating the incidences in the cohort to an age-matched material from the Swedish background population. RESULTS: A higher overall incidence of malignancies than the background population was found, counting from the date of diagnosis (standard incidence ratio (SIR) 2.08, 95% CI 1.68-2.55). The highest risk was found for hepatocellular carcinoma (HCC). We found 10 cases (4.0%) in 248 patients with cirrhosis, which gives an incidence rate of 0.3%. Standard incidence ratio for developing hepatobiliary cancer was 54.55 (95% CI 19.92-99.99). HCC only occurred in cirrhotic patients. There was also an increased risk for non-melanoma skin cancer (SIR 9.87, 95% CI 6.26-14.81). CONCLUSION: A slightly enhanced risk for malignancies in general compared to the background population was found. The risk of hepatobiliary cancer was increased, but the annual risk over the observational period was well under the postulated 1.5% when surveillance in cirrhotic patients is considered to be cost-effective.

RESUMO

The role of workplace supervisors in the clinical education of medical students is currently under debate. However, few studies have addressed how supervisors conceptualize workplace learning and how conceptions relate to current sociocultural workplace learning theory. We explored physician conceptions of: (a) medical student learning in the clinical workplace and (b) how they contribute to student learning. The methodology included a combination of a qualitative, inductive (conventional) and deductive (directed) content analysis approach. The study triangulated two types of interview data from 4 focus group interviews and 34 individual interviews. A total of 55 physicians participated. Three overarching themes emerged from the data: learning as membership, learning as partnership and learning as ownership. The themes described how physician conceptions of learning and supervision were guided by the notions of learning-as-participation and learning-as-acquisition. The clinical workplace was either conceptualized as a context in which student learning is based on a learning curriculum, continuity of participation and partnerships with supervisors, or as a temporary source of knowledge within a teaching curriculum. The process of learning was shaped through the reciprocity between different factors in the workplace context and the agency of students and supervising physicians. A systems-thinking approach merged with the "co-participation" conceptual framework advocated by Billet proved to be useful for analyzing variations in conceptions. The findings suggest that mapping workplace supervisor conceptions of learning can be a valuable starting point for medical schools and educational developers working with changes in clinical educational and faculty development practices.

RESUMO

OBJECTIVE: Our aims were to investigate the natural history of biopsy-proven non-alcoholic fatty liver disease (NAFLD) in Sweden, its associated complications, the clinical and biochemical factors associated with more advanced liver disease and the survival rate with a mean follow-up time of 27 years. MATERIAL AND METHODS: All subjects participating in the population-based prospective cohort study Malmö Preventive Project (MPP) from 1974 to 1992 who had undergone liver biopsy with the diagnosis of NAFLD were included. The remaining MPP cohort was used as a control group. Subjects with other liver diseases and alcohol overconsumption were excluded. A panel of blood tests was analyzed in the MPP cohort. Follow-up of the NAFLD patients included studies of medical records, pathology records and mortality rates from the Swedish National Board of Health and Welfare's register until the end of 2011. RESULTS: A total of 36 patients were diagnosed with biopsy-proven NAFLD. Median follow-up time was 27.0 years (6.32-35.3). Nine patients (25%) were diagnosed with cirrhosis and five (14%) with hepatocellular cancer, all with a previous diagnosis of cirrhosis. There were significant differences in liver function tests, insulin resistance (as homeostasis model assessment of insulin resistance) and body mass index (BMI) in patients with NAFLD compared with the control group. Mortality in the NAFLD group was significantly higher, 58.3% compared to 33.8% (p = 0.004). Hepatocellular cancer accounted for 23.8% of all deaths in the NAFLD group, compared to 0.7% (p = 0.000). CONCLUSIONS: NAFLD can progress to advanced liver disease, including cirrhosis, with a higher than expected mortality and incidence of hepatocellular cancer.

RESUMO

OBJECTIVE: Anti-neutrophil cytoplasmic antibodies and anti-Saccharomyces cerevisiae mannan antibodies (ASCAs) have been detected in the serum of patients with ulcerative colitis (UC) and Crohn's disease (CD) and their unaffected family members. The aim of this study was to establish the value of serological markers as predictors of UC and CD. DESIGN: Individuals who developed CD or UC were identified from the European Prospective Investigation into Cancer and Nutrition (EPIC) study. At recruitment, none of the participants had a diagnosis of CD or UC. For each incident case, two controls were randomly selected matched for centre, date of birth, sex, date of recruitment and time of follow-up. Serum of cases and controls obtained at recruitment were analysed for ASCA IgG, ASCA IgA, perinuclear anti-neutrophil cytoplasmic antibody (pANCA), antibodies against Escherichia coli outer membrane porin C (OmpC) and flagellin CBir1. Conditional logistic regression was used to determine risk of CD and UC. Receiver operating characteristic curves were constructed to test accuracy. RESULTS: A total of 77 individuals were diagnosed with CD and 167 with UC after a mean follow-up of 4.5 (SD 3.2) and 4.4 (SD 3.1) years following blood collection, respectively. Combinations of pANCA, ASCA, anti-CBir1 and anti-OmpC were most accurate in predicting incident CD and UC (area under curve 0.679 and 0.657, respectively). The predictive value of the combination of markers increased when time to diagnosis of CD or UC decreased. CONCLUSION: A panel of serological markers is able to predict development of CD and UC in individuals from a low-risk population.

RESUMO

OBJECTIVES: Obesity is associated with a proinflammatory state that may be involved in the etiology of inflammatory bowel disease (IBD), for which there are plausible biological mechanisms. Our aim was to perform the first prospective cohort study investigating if there is an association between obesity and the development of incident IBD. METHODS: A total of 300,724 participants were recruited into the European Prospective Investigation into Cancer and Nutrition study. At recruitment, anthropometric measurements of height and weight plus physical activity and total energy intake from validated questionnaires were recorded. The cohort was monitored identifying participants who developed either Crohn's disease (CD) or ulcerative colitis (UC). Each case was matched with four controls and conditional logistic regression used to calculate odds ratios (ORs) for body mass index (BMI) adjusted for smoking, energy intake, and physical activity. RESULTS: In the cohort, 177 participants developed incident UC and 75 participants developed incident CD. There were no associations with the four higher categories of BMI compared with a normal BMI for UC (Ptrend=0.36) or CD (Ptrend=0.83). The lack of associations was consistent when BMI was analyzed as a continuous or binary variable (BMI 18.5<25.0 vs. ≥25 kg/m(2)). Physical activity and total energy intake, factors that influence BMI, did not show any association with UC (physical activity, Ptrend=0.79; total energy intake, Ptrend=0.18) or CD (physical activity, Ptrend=0.42; total energy, Ptrend=0.11). CONCLUSIONS: Obesity as measured by BMI is not associated with the development of incident UC or CD. Alternative measures of obesity are required to further investigate the role of obesity in the development of incident IBD.

RESUMO

OBJECTIVE: The prevalence of anemia in inflammatory bowel disease (IBD) has been broadly described. The recurrence, type and burden of anemia remain unenlightened. The primary objective was to describe this. The secondary objective was to evaluate the implementation of European guidelines. MATERIALS AND METHODS: This longitudinal follow-up study included 300 IBD outpatients from six centers in Scandinavia. Patients were enrolled in a research cohort, in which each center included 5% of their IBD cohort. The study was prospectively planned, while data were retrospectively collected. The burden of anemia was calculated as number of months with anemia. A Markov model was used to calculate the probabilities of transitioning between stages. The European guidelines were used as the standard for anemia management. RESULTS: Anemia affected > 50% of IBD outpatients during the 2-year observation period. Totally, 20% of the total observation time was spent in anemia. Over the 7200 months of observation, anemia was found in 1410 months. The most frequent type was combined anemia (63%). Combined anemia covers both anemia of chronic disease (ACD) and iron-deficiency anemia (IDA). Pure ACD was present in 21% of burden time, while pure IDA was present in 16% of burden time. The European guidelines have mainly been implemented. CONCLUSION: Anemia affected a majority of the IBD outpatients. One in five months, the patients were anemic. Anemia related to inflammation dominated the different types of anemia. Pure IDA was found in for 16%. These findings, despite a fair implementation of guidelines.

RESUMO

To secure high-quality education for healthcare professionals, the teaching and learning processes-the "how" in education-should be informed by a research base. Although Swedish medical education research is growing, it lacks a national strategy. This study analysed and compared Swedish and Dutch production of medical education articles over ten years in nine core journals, including the number of editorial board members.  During the period 2012-2021, Swedish authors produced 217 articles, whereas Dutch authors published 1,441. The journals had 466 board members, of which 31 (7%) were Dutch and four (<1%) Swedish. The results show that medical education in Swedish medical faculties requires improvement. To ensure high-quality education opportunities, we propose a national effort to strengthen the educational research base, using the Dutch effort as inspiration.

RESUMO

Iron deficiency, defined as ferritin <100 µg/L or ferritin 100-299 µg/L if the transferrin saturation is <20 %, with or without anaemia is a common comorbidity in patients with acute and chronic heart failure. International and Swedish guidelines recommend treatment of iron deficiency with intravenous iron in patients with symptomatic heart failure and ejection fraction <50 %. Controlled studies document positive effects from treatment with iron carboxymaltose on symptoms, quality of life, functional parameters and risk of hospitalisation. We present a simple algoritm based on published data to help the responsible physician to manage these patients in clinical practice.

RESUMO

BACKGROUND AND AIMS: We aimed to investigate the association between protein intake and risk of inflammatory bowel disease [IBD] in the European Prospective Investigation into Cancer and Nutrition. METHODS: A total of 413 593 participants from eight European countries were included. Dietary data were collected at baseline from validated food frequency questionnaires. Dietary data were calibrated to correct errors in measures related to each country-specific questionnaire. Associations between proteins [total, animal, and vegetable] or food sources of animal proteins, and IBD risk were estimated by Cox proportional hazard models. RESULTS: After a mean follow-up of 16 years, 177 patients with Crohn's disease [CD] and 418 with ulcerative colitis [UC], were identified. There was no association between total protein, animal protein, or vegetable protein intakes and CD or UC risks. Total meat and red meat intakes were associated with UC risk (hazard ratio [HR] for the 4th vs 1st quartile = 1.40, 95% confidence interval [CI] = 0.99-1.98, p-trend = 0.01; and 1.61, 95% CI = 1.10-2.36, p-trend = 0.007, respectively]. There was no association between other food sources of animal protein [processed meat, fish, shellfish, eggs, poultry] and UC. We found no association between food sources of animal proteins and CD risk. CONCLUSIONS: Meat and red meat consumptions are associated with higher risks of UC. These results support dietary counselling of low meat intake in people at high-risk of IBD.

RESUMO

OBJECTIVE: To evaluate the prevalence of anemia and iron deficiency (ID) among patients with inflammatory bowel disease (IBD) in the Scandinavian countries. MATERIAL AND METHODS: A cross-sectional study including 429 IBD patients from six centers in Denmark, Norway and Sweden. Patients were screened for anemia and ID. Each center included ~5% of their IBD cohort. Patients were consecutively seen in the outpatient clinic, regardless of disease activity and whether the visits were scheduled or not. RESULTS: The overall prevalence of anemia was 19% (95% CI: 16-23%). The prevalence was higher among patients with Crohn's disease than among patients with ulcerative colitis (p = 0.01). The etiology of anemia was as follows: iron deficiency anemia (20%), anemia of chronic disease (12%), and both conditions (68%). Less than 5% had folate acid or vitamin B12 deficiency. ID was found in 35% (CI: 31-40%) of the patients. CONCLUSIONS: Anemia was present in every fifth IBD patient and ID in every third IBD patient.

RESUMO

OBJECTIVE: The information concerning the morbidity and mortality of hereditary hemochromatosis is based primarily on clinical cohorts of symptomatic patients. The major aim of this study was to analyze the long-term prognosis for Swedish patients with this condition, with respect to both clinical features and survival, in relation to the route by which the disease was detected. PATIENTS AND METHODS: 373 patients with hemochromatosis detected through routine health check-ups (n = 153), family screening (n = 44), symptoms of arthralgia (n = 23), investigation of other diseases/symptoms (n = 108) or signs of liver disease (n = 45) were monitored for a mean period of 11.9 ± 5.8 years. The degree of liver fibrosis and survival were analyzed. RESULTS: Overall survival among these patients was not significantly different from that of a matched normal population. The patients diagnosed through health check-ups and family screening were detected at an earlier age and had the highest rate of survival. Liver biopsy at the time of diagnosis revealed cirrhosis in 9% of those detected through the health check-ups and 5% in the case of family screening, compared with 13% for the group with arthralgia, 17% for other diseases/symptoms and 42% for liver disease. CONCLUSION: Health check-ups and family screening allow detection of hereditary hemochromatosis at an earlier age and with less advanced liver fibrosis, although a few of these patients have already developed cirrhosis. Our study indicates that iron indices should be included in health check-ups, and if abnormal, should lead to further investigation.

RESUMO

Health care is deficient in many parts of the world, in money, facilities and manpower. In wealthy countries, the costs and complexity of health care are increasing unsustainably. Nevertheless, richer countries claim an ever escalating need for doctors, who migrate from poorer countries, with an ensuing global health workforce crisis. These political, social, demographic and international events necessitate a discussion on the roles and values of the doctor in the world today. The international mobility of both doctors and patients underlines the need for a global definition. Only when these roles and values are agreed in a global perspective, will medical education be capable of producing a professional equipped to fulfil that role. This doctor will then be useful both as a leader and as a member of health care teams with a flexible composition, related to resources and needs of particular regions, and at the same time be able to practise within any given health care system. An international task-force of the World Federation for Medical Education (WFME) is working to agree themes relevant to the role of the doctor globally, and developing a statement that can be used world-wide, and used to develop medical education policy.
