Is the Internet a useful and relevant source for health and health care information retrieval for German cardiothoracic patients? First results from a prospective survey among 255 Patients at a German cardiothoracic surgical clinic

BACKGROUND: It is not clear how prevalent Internet use among cardiopathic patients in Germany is and what impact it has on the health care utilisation. We measured the extent of Internet use among cardiopathic patients and examined the effects that Internet use has on users' knowledge about their cardiac disease, health care matters and their use of the health care system. METHODS: We conducted a prospective survey among 255 cardiopathic patients at a German university hospital. RESULTS: Forty seven respondents (18 %) used the internet and 8,8 % (n = 23) went online more than 20 hours per month. The most frequent reason for not using the internet was disinterest (52,3 %). Fourteen patients (5,4 %) searched for specific disease-related information and valued the retrieved information on an analogous scale (1 = not relevant, 5 = very relevant) on median with 4,0. Internet use is age and education dependent. Only 36 (14,1 %) respondents found the internet useful, whereas the vast majority would not use it. Electronic scheduling for ambulatory visits or postoperative telemedical monitoring were rather disapproved. CONCLUSION: We conclude that Internet use is infrequent among our study population and the search for relevant health and disease related information is not well established

Differentiation between rebound thymic hyperplasia and thymic relapse after chemotherapy in pediatric Hodgkin lymphoma

Rebound thymic hyperplasia (RTH) is a common phenomenon caused by stress factors such as chemotherapy (CTX) or radiotherapy, with an incidence between 44% and 67.7% in pediatric lymphoma. Misinterpretation of RTH and thymic lymphoma relapse (LR) may lead to unnecessary diagnostic procedures including invasive biopsies or treatment intensification. The aim of this study was to identify parameters that differentiate between RTH and thymic LR in the anterior mediastinum. After completion of CTX, we analyzed computed tomographies (CTs) and magnetic resonance images (MRIs) of 291 patients with classical Hodgkin lymphoma (CHL) and adequate imaging available from the European Network for Pediatric Hodgkin lymphoma C1 trial. In all patients with biopsy-proven LR, an additional fluorodeoxyglucose (FDG)-positron emission tomography (PET)-CT was assessed. Structure and morphologic configuration in addition to calcifications and presence of multiple masses in the thymic region and signs of extrathymic LR were evaluated. After CTX, a significant volume increase of new or growing masses in the thymic space occurred in 133 of 291 patients. Without biopsy, only 98 patients could be identified as RTH or LR. No single finding related to thymic regrowth allowed differentiation between RTH and LR. However, the vast majority of cases with thymic LR presented with additional increasing tumor masses (33/34). All RTH patients (64/64) presented with isolated thymic growth. Isolated thymic LR is very uncommon. CHL relapse should be suspected when increasing tumor masses are present in distant sites outside of the thymic area. Conversely, if regrowth of lymphoma in other sites can be excluded, isolated thymic mass after CTX likely represents RTH

Response-adapted omission of radiotherapy and comparison of consolidation chemotherapy in intermediate- and advanced-stage children and adolescents with classic Hodgkin lymphoma: a titration study with an embedded non-inferiority randomised controlled trial

BACKGROUND: Children and adolescents with intermediate-stage and advanced-stage classical Hodgkin lymphoma achieve an event-free survival at 5 years of about 90% after treatment with vincristine, etoposide, prednisone, and doxorubicin (OEPA) followed by cyclophosphamide, vincristine, prednisone, and procarbazine (COPP) and radiotherapy, but long-term treatment effects affect survival and quality of life. We aimed to investigate whether radiotherapy can be omitted in patients with morphological and metabolic adequate response to OEPA and whether modified consolidation chemotherapy reduces gonadotoxicity. METHODS: Our study was designed as a titration study with an open-label, embedded, multinational, non-inferiority, randomised controlled trial, and was carried out at 186 hospital sites across 16 European countries. Children and adolescents with newly diagnosed intermediate-stage (treatment group 2) and advanced-stage (treatment group 3) classical Hodgkin lymphoma who were younger than 18 years and stratified according to risk using Ann Arbor disease stages IIAE, IIB, IIBE, IIIA, IIIAE, IIIB, IIIBE, and all stages IV (A, B, AE, and BE) were included in the study. Patients with early disease (treatment group 1) were excluded from this analysis. All patients were treated with two cycles of OEPA (1·5 mg/m(2) vincristine taken intravenously capped at 2 mg, on days 1, 8, and 15; 125 mg/m(2) etoposide taken intravenously on days 1–5; 60 mg/m(2) prednisone taken orally on days 1–15; and 40 mg/m(2) doxorubicin taken intravenously on days 1 and 15). Patients were randomly assigned to two (treatment group 2) or four (treatment group 3) cycles of COPP (500 mg/m(2) cyclophosphamide taken intravenously on days 1 and 8; 1·5 mg/m(2) vincristine taken intravenously capped at 2 mg, on days 1 and 8; 40 mg/m(2) prednisone taken orally on days 1 to 15; and 100 mg/m(2) procarbazine taken orally on days 1 to 15) or COPDAC, which was identical to COPP except that 250 mg/m(2) dacarbazine administered intravenously on days 1 to 3 replaced procarbazine. The method of randomisation (1:1) was minimisation with stochastic component and was centrally stratified by treatment group, country, trial sites, and sex. The primary endpoint was event-free survival, defined as time from treatment start until the first of the following events: death from any cause, progression or relapse of classical Hodgkin lymphoma, or occurrence of secondary malignancy. The primary objectives were maintaining 90% event-free survival at 5 years in patients with adequate response to OEPA treated without radiotherapy and to exclude a decrease of 8% in event-free survival at 5 years in the embedded COPDAC versus COPP randomisation to show non-inferiority of COPDAC. Efficacy analyses are reported per protocol and safety in the intention-to-treat population. The trial is registered with ClinicalTrials.gov (trial number NCT00433459) and EUDRACT (trial number 2006-000995-33), and is closed to recruitment. FINDINGS: Between Jan 31, 2007, and Jan 30, 2013, 2102 patients were recruited. 737 (35%) of the 2102 recruited patients were in treatment group 1 (early-stage disease) and were not included in our analysis. 1365 (65%) of the 2102 patients were in treatment group 2 (intermediate-stage disease; n=455) and treatment group 3 (advanced-stage disease; n=910). Of these 1365, 1287 (94%) patients (435 [34%] of 1287 in treatment group 2 and 852 [66%] of 1287 in treatment group 3) were included in the titration trial per-protocol analysis. 937 (69%) of 1365 patients were randomly assigned to COPP (n=471) or COPDAC (n=466) in the embedded trial. Median follow-up was 66·5 months (IQR 62·7–71·7). Of 1287 patients in the per-protocol group, 514 (40%) had an adequate response to treatment and were not treated with radiotherapy (215 [49%] of 435 in treatment group 2 and 299 [35%] of 852 in treatment group 3). 773 (60%) of 1287 patients with inadequate response were scheduled for radiotherapy (220 [51%] of 435 in the treatment group 2 and 553 [65%] of 852 in treatment group 3. In patients who responded adequately, event-free survival rates at 5 years were 90·1% (95% CI 87·5–92·7). event-free survival rates at 5 years in 892 patients who were randomly assigned to treatment and analysed per protocol were 89·9% (95% CI 87·1–92·8) for COPP (n=444) versus 86·1% (82·9–89·4) for COPDAC (n=448). The COPDAC minus COPP difference in event-free survival at 5 years was −3·7% (−8·0 to 0·6). The most common grade 3–4 adverse events (intention-to-treat population) were decreased haemoglobin (205 [15%] of 1365 patients during OEPA vs 37 [7%] of 528 treated with COPP vs 20 [2%] of 819 treated with COPDAC), decreased white blood cells (815 [60%] vs 231 [44%] vs 84 [10%]), and decreased neutrophils (1160 [85%] vs 223 [42%] vs 174 [21%]). One patient in treatment group 2 died of sepsis after the first cycle of OEPA; no other treatment-related deaths occurred. INTERPRETATION: Our results show that radiotherapy can be omitted in patients who adequately respond to treatment, when consolidated with COPP or COPDAC. COPDAC might be less effective, but is substantially less gonadotoxic than COPP. A high proportion of patients could therefore be spared radiotherapy, eventually reducing the late effects of treatment. With more refined criteria for response assessment, the number of patients who receive radiotherapy will be further decreased.

Empowerment for the Digital Transformation: Results of a Structured Blended-Learning On-the-Job Training for Practicing Physicians in Germany

(1) Background: Practicing physicians have not been in the focus of structured qualifications in basic digital competences so far. However, they are the current gatekeepers to implement digital technologies and need empowerment to proactively take part in the ongoing digital transformation process. The present study investigates if a structured blended-learning training for practicing physicians in Germany enhances both physicians’ knowledge about central aspects of the digital transformation (including awareness of personal possibilities to act) and their attitudes towards a more digitally empowered mindset. (2) Methods: Participants (n = 32) self-assessed their knowledge (19 items, 10-point Likert-scale) and attitudes (6 items, 5-point Likert-scale) towards the digital transformation at the beginning and at the end of the training. MANCOVAs were conducted. (3) Results: Participants reported an increase in every knowledge domain, representing large effects (Hedges’ g 1.06 to 2.82). Attitudes were partly shifted towards a more empowered mindset with decreased insecurity towards technological, legal, and ethical aspects of the digital transformation (Hedges’ g −0.82 to −1.40). However, preparedness for the digital transformation remained low. (4) Conclusions: Generally, the hypotheses were confirmed. The presented on-the-job training had the desired effects on practicing physicians’ knowledge and attitudes. Nevertheless, additional empowerment and support are essential

Analysis of 30 anaesthesia-related deaths in Germany between 2006 and 2015: An analysis of a closed claims database.

BACKGROUND Anaesthesiology is one of the safest fields in medicine today in relation to mortality. Deaths directly because of anaesthesia have fortunately now become rare exceptions. Nevertheless, important findings can still be drawn from the rare deaths that still occur. OBJECTIVE The aim of this study was to identify and analyse the causes of deaths related to anaesthesia alone over a 10-year period. DESIGN Retrospective structured analysis of a database of medical liability claims. SETTING Hospitals at all levels of care in Germany. PATIENTS The database of a large insurance broker included data for 81 413 completed liability claims over the 10-year period from 2006 to 2015. Among 1914 cases associated with anaesthetic procedures, 56 deaths were identified. Of these, 30 clearly involved anaesthesia (Edwards category 1) and were included in the evaluation. INTERVENTIONS None (retrospective database analysis). MAIN OUTCOME MEASURES Causes of anaesthesia-related death identified from medical records, court records, expert opinions and autopsy reports. RESULTS The 30 deaths were analysed in detail at the case and document level. They included high proportions of 'potentially avoidable' deaths, at 86.6%, and what are termed 'never events', at 66.7%. Problems with the airway were the cause in 40% and problems with correct monitoring in 20%. In addition, communication problems were identified as a 'human factor' in 50% of the cases. CONCLUSION The majority of the anaesthesia-related deaths investigated could very probably have been avoided with simple anaesthesiological measures if routine guidelines had been followed and current standards observed. Actions to be taken are inferred from these results, and recommendations are made. In future, greater care must be taken to ensure that the level of safety already achieved in anaesthesiology can be maintained despite demographic developments and increasing economic pressures

Whole-body muscle MRI of patients with MATR3-associated distal myopathy reveals a distinct pattern of muscular involvement and highlights the value of whole-body examination

Objective!#!MATR3-associated distal myopathy is a rare distal myopathy predominantly affecting lower legs as well as wrist- and finger extensors. Whilst most distal myopathies are clinically and genetically well characterized, diagnosis often remains challenging. Pattern-based magnetic resonance imaging (MRI) approaches offer valuable additional information. However, a consistent pattern of muscular affection is missing for most distal myopathies. Thus, the aim of the present study was to establish a disease-specific pattern of muscular involvement in MATR3-associated distal myopathy using whole-body MRI.!##!Methods!#!15 patients (25-79 years of age, 7 female) with MATR3-associated distal myopathy were subjected to whole-body MRI. The grade of fatty involution for individual muscles was determined using Fischer-Grading. Results were compared to established MRI-patterns of other distal myopathies.!##!Results!#!There was a predominant affection of the distal lower extremities. Lower legs showed a severe fatty infiltration, prominently affecting gastrocnemius and soleus muscle. In thighs, a preferential involvement of semimembranous and biceps femoris muscle was observed. Severe affection of gluteus minimus muscle as well as axial musculature, mainly affecting the thoracic segments, was seen. A sufficient discrimination to other forms of distal myopathy based solely on MRI-findings of the lower extremities was not possible. However, the inclusion of additional body parts seemed to yield specificity.!##!Interpretation!#!Muscle MRI of patients with MATR3-associated distal myopathy revealed a distinct pattern of muscular involvement. The usage of whole-body muscle MRI provided valuable additional findings as compared to regular MRI of the lower extremities to improve distinction from other disease entities

Einsatz von Simulationspersonen im Dritten Abschnitt der Ärztlichen Prüfung

In order to protect patients and students during the Covid 19 pandemic, the third section of the medical examination (M3) in Halle (Saale) was conducted in a modified form in accordance with the "Verordnung zur Abweichung von der Approbationsordnung für Ärzte bei einer epidemischen Lage von nationaler Tragweite” [1]. The one-day examination took place at the Dorothea Erxleben Learning Center (DELH) of the Martin Luther University Halle-Wittenberg on standardized simulation subjects. In contrast to previous years, all examiners were examined individually in internal medicine, surgery and their elective subject of the practical year. In the evaluations carried out, the standardized cases were assessed as consistent and fair by examiners and exam takers. Approximately 90% of the examiners could imagine to test a state examination with simulated patients again. After successful pilot testing, a study will be conducted in the coming exam to determine whether the substitution of real patients with simulated patients in the M3 exam can contribute to better standardization and objectivity while maintaining the same high level of acceptance in the exam. Whether the high acceptance will remain constant can only be checked in the course of the study.Um Patient*innen und Student*innen während der Covid-19-Pandemie zu schützen, wurde der Dritte Abschnitt der Ärztlichen Prüfung (M3) in Halle (Saale) in abgewandelter Form gemäß „Verordnung zur Abweichung von der Approbationsordnung für Ärzte bei einer epidemischen Lage von nationaler Tragweite“ durchgeführt. Die eintägige Prüfung fand im Dorothea Erxleben Lernzentrum (DELH) der Martin-Luther-Universität Halle-Wittenberg an standardisierten Simulationspersonen statt. Alle Prüfungsteilnehmer*innen wurden im Gegensatz zu den Vorjahren einzeln in Innerer Medizin, Chirurgie und ihrem Wahlfach des Praktischen Jahres geprüft. In den durchgeführten Evaluationen wurden die standardisierten Fälle von Prüfer*innen und Prüfungsteilnehmer*innen als in sich stimmig und fair bewertet. So konnten sich circa 90% der Prüfer*innen vorstellen, erneut ein Staatsexamen mit Simulationspersonen zu prüfen. Nach erfolgreicher Pilotierung soll im kommenden Examen im Rahmen einer Studie untersucht werden, ob die Substitution von Realpatienten durch Simulationspersonen in der M3-Prüfung zu einer besseren Standardisierung und Objektivität bei gleichbleibend hoher Akzeptanz im Examen beitragen kann. Ob die hohe Akzeptanz weiterhin konstant bleiben wird, kann nur im Verlauf der Studie überprüft werden
