A network medicine approach to study comorbidities in heart failure with preserved ejection fraction.

BACKGROUND: Comorbidities are expected to impact the pathophysiology of heart failure (HF) with preserved ejection fraction (HFpEF). However, comorbidity profiles are usually reduced to a few comorbid disorders. Systems medicine approaches can model phenome-wide comorbidity profiles to improve our understanding of HFpEF and infer associated genetic profiles. METHODS: We retrospectively explored 569 comorbidities in 29,047 HF patients, including 8062 HFpEF and 6585 HF with reduced ejection fraction (HFrEF) patients from a German university hospital. We assessed differences in comorbidity profiles between HF subtypes via multiple correspondence analysis. Then, we used machine learning classifiers to identify distinctive comorbidity profiles of HFpEF and HFrEF patients. Moreover, we built a comorbidity network (HFnet) to identify the main disease clusters that summarized the phenome-wide comorbidity. Lastly, we predicted novel gene candidates for HFpEF by linking the HFnet to a multilayer gene network, integrating multiple databases. To corroborate HFpEF candidate genes, we collected transcriptomic data in a murine HFpEF model. We compared predicted genes with the murine disease signature as well as with the literature. RESULTS: We found a high degree of variance between the comorbidity profiles of HFpEF and HFrEF, while each was more similar to HFmrEF. The comorbidities present in HFpEF patients were more diverse than those in HFrEF and included neoplastic, osteologic and rheumatoid disorders. Disease communities in the HFnet captured important comorbidity concepts of HF patients which could be assigned to HF subtypes, age groups, and sex. Based on the HFpEF comorbidity profile, we predicted and recovered gene candidates, including genes involved in fibrosis (COL3A1, LOX, SMAD9, PTHL), hypertrophy (GATA5, MYH7), oxidative stress (NOS1, GSST1, XDH), and endoplasmic reticulum stress (ATF6). Finally, predicted genes were significantly overrepresented in the murine transcriptomic disease signature providing additional plausibility for their relevance. CONCLUSIONS: We applied systems medicine concepts to analyze comorbidity profiles in a HF patient cohort. We were able to identify disease clusters that helped to characterize HF patients. We derived a distinct comorbidity profile for HFpEF, which was leveraged to suggest novel candidate genes via network propagation. The identification of distinctive comorbidity profiles and candidate genes from routine clinical data provides insights that may be leveraged to improve diagnosis and identify treatment targets for HFpEF patients.

Psychosocial Characteristics of Patients Evaluated for Kidney, Liver, or Heart Transplantation.

OBJECTIVE: Psychosocial parameters play a pivotal role in organ recipient evaluation before wait-listing for transplantation because of their impact on organ and patient outcome. Patients in need of heart (HTx), liver (LTx), or kidney transplantation (KTx) face distinct physical and psychological challenges. This study compares the psychosocial characteristics and preferences for additional therapy for patients undergoing assessment for these three types of organ transplantation to optimize patient-tailored psychological, social, and other supportive interventions. METHODS: We conducted a cross-sectional, observational study with 1110 potential transplantation candidates (LTx, n = 544; KTx, n = 330; HTx, n = 236), psychosocial status was determined for depressive symptoms (Patient Health Questionnaire Depression Scale), anxiety symptoms (seven-item Generalized Anxiety Disorder Screener), health-related quality of life (36-Item Short Form Health Survey), perceived social support (Perceived Social Support Questionnaire), sense of coherence (SoC; short form of the Sense of Coherence Scale), self-efficacy (General Self-Efficacy Short Scale), and body image (German Body Image Questionnaire-20). Preferences for additional supportive therapy were assessed dichotomously. Data were analyzed using multivariate analysis of covariance and χ2 tests. RESULTS: Patient groups differed significantly regarding depression ( F (2,1107) = 35.283, p < .001, partial η2 = 0.01), anxiety ( F (2,1107) = 15.027, p < .001, partial η2 = 0.03), health-related quality of life (physical: F (2,1107) = 96.772, p < .001, partial η2 = 0.15; mental: F (2,1107) = 11.442, p < .001, partial η2 = 0.02), perceived social support ( F (2,1107) = 20.813, p < .001, partial η2 = 0.04), SoC ( F (2,1107) = 12.920, p < .001, partial η2 = 0.02), self-efficacy ( F (2,1107) = 17.308, p < .001, partial η2 = 0.03), and body image (rejecting body evaluation: F (2,1107) = 5.006, p = .007, partial η2 = 0.01; vital body dynamics: F (2,1107) = 40.216, p < .001, partial η2 = 0.07). Patients evaluated for HTx showed the highest psychosocial impairment and the highest inclination regarding additional supportive therapy. CONCLUSIONS: Patients evaluated for HTx, LTx, and KTx have distinct psychosocial characteristics and treatment preferences. HTx patients display the highest psychosocial impairment. We suggest psychocardiological treatment structures for optimal outcome.

Forebrain corticosteroid receptors promote post-myocardial infarction depression and mortality.

Myocardial infarction (MI) with subsequent depression is associated with increased cardiac mortality. Impaired central mineralocorticoid (MR) and glucocorticoid receptor (GR) equilibrium has been suggested as a key mechanism in the pathogenesis of human depression. Here, we investigate if deficient central MR/GR signaling is causative for a poor outcome after MI in mice. Mice with an inducible forebrain-specific MR/GR knockout (MR/GR-KO) underwent baseline and follow-up echocardiography every 2 weeks after MI or sham operation. Behavioral testing at 4 weeks confirmed significant depressive-like behavior and, strikingly, a higher mortality after MI, while cardiac function and myocardial damage remained unaffected. Telemetry revealed cardiac autonomic imbalance with marked bradycardia and ventricular tachycardia (VT) upon MI in MR/GR-KO. Mechanistically, we found a higher responsiveness to atropine, pointing to impaired parasympathetic tone of 'depressive' mice after MI. Serum corticosterone levels were increased but-in line with the higher vagal tone-plasma and cardiac catecholamines were decreased. MR/GR deficiency in the forebrain led to significant depressive-like behavior and a higher mortality after MI. This was accompanied by increased vagal tone, depleted catecholaminergic compensatory capacity and VTs. Thus, limbic MR/GR disequilibrium may contribute to the impaired outcome of depressive patients after MI and possibly explain the lack of anti-depressive treatment benefit.

Communication Skills (CS) training of physicians in China and its role in actual challenges of patient-physician relationship: a cross-sectional survey.

BACKGROUND: The Chinese healthcare system is affected by frequent disputes between physicians and patients. Although recent reforms have contributed towards improving the patient-physician relationship, distrust in physicians is still high. Communication skills (CS) training of physicians holds the key to improving patient confidence and diffusing stressful situations. This survey reports on the status of CS training in medical education in China, and the experiences and attitudes of physicians towards CS training. METHODS: A cross-sectional survey was conducted at medical institutions across China. A questionnaire developed for this study included the status of CS training, current aspects of patient-physician relationships, perceived own CS and patient-centeredness with Likert-scaled items from 1 (most negative) to 6 (most positive). Physicians' attitude towards CS training was measured with the Communication Skills Attitude Scale (CSAS) and its subscales PAS (Positive Attitude Scale) and NAS (Negative Attitude Scale). Data were analyzed descriptively and for group differences between the hospital level and operating vs. non-operating physicians. Binary logistic regression analysis was done to find associations explaining the occurrence of verbal and physical attacks and the role of CS attitudes. RESULTS: Out of 1080 questionnaires, 772 physicians met inclusion criteria. A total of 466/772 participants (60.4%) had received at least one CS training during their career. The participants rated the current situation related to patient-physician relationship in China as highly stressful (mean = 4.52, SD = 1.26, 95% CI: 4.43-4.60), experiencing verbal attacks in the past three years once a year in 372/772 cases (48.2%) and physical attacks 111/772 times (14.4%). The mean PAS was 62.96 (SD = 7.63, 95% CI: 62.41-63.47). Being female was associated with increased risk of verbal attacks (OR = 1.51, 95% CI: 1.01-2.25) while working in a tertiary hospital and showing high levels of PAS decreased this risk (OR = 0.62, 95% CI: 0.43-0.89, and OR = 0.95, 95% CI: 0.93-0.98). Having received a previous CS training decreased the odds of physical attacks (OR = 0.54, 95% CI: 0.35-0.83). CONCLUSIONS: A majority of Chinese physicians showed a high positive attitude towards CS training, were trained in CS and would value further training. Our results highlight that CS training is likely to promote patient-centered communication and reduce attacks against physicians. Both of these effects are to improve the patient-physician-relationship in the long run. More CS training should be offered to Chinese physicians, especially at secondary- and primary-care hospitals, where such practices remain infrequent.

Mental Health Among Medical Professionals During the COVID-19 Pandemic in Eight European Countries: Cross-sectional Survey Study.

BACKGROUND: The death toll of COVID-19 topped 170,000 in Europe by the end of May 2020. COVID-19 has caused an immense psychological burden on the population, especially among doctors and nurses who are faced with high infection risks and increased workload. OBJECTIVE: The aim of this study was to compare the mental health of medical professionals with nonmedical professionals in different European countries during the COVID-19 pandemic. We hypothesized that medical professionals, particularly those exposed to COVID-19 at work, would have higher levels of depression, anxiety, and stress. We also aimed to determine their main stressors and most frequently used coping strategies during the crisis. METHODS: A cross-sectional online survey was conducted during peak COVID-19 months in 8 European countries. The questionnaire included demographic data and inquired whether the participants were exposed to COVID-19 at work or not. Mental health was assessed via the Depression Anxiety Stress Scales32 (23.53)-21 (DASS-21). A 12-item checklist on preferred coping strategies and another 23-item questionnaire on major stressors were completed by medical professionals. RESULTS: The sample (N=609) consisted of 189 doctors, 165 nurses, and 255 nonmedical professionals. Participants from France and the United Kingdom reported experiencing severe/extremely severe depression, anxiety, and stress more often compared to those from the other countries. Nonmedical professionals had significantly higher scores for depression and anxiety. Among medical professionals, no significant link was reported between direct contact with patients with COVID-19 at work and anxiety, depression, or stress. "Uncertainty about when the epidemic will be under control" caused the most amount of stress for health care professionals while "taking protective measures" was the most frequently used coping strategy among all participants. CONCLUSIONS: COVID-19 poses a major challenge to the mental health of working professionals as a considerable proportion of our participants showed high values for depression, anxiety, and stress. Even though medical professionals exhibited less mental stress than nonmedical professionals, sufficient help should be offered to all occupational groups with an emphasis on effective coping strategies.

Teaching patient-centred communication skills during clinical procedural skill training - a preliminary pre-post study comparing international and local medical students.

BACKGROUND: International medical students are frequently confronted with intercultural, psychosocial, and language barriers and often receive lower marks in written, oral, and clinical-practical examinations than fellow local students. Training communication competence in procedural skills, such as blood sampling, is further challenge in this particular group of medical students. This pre-post comparative intervention study aimed to investigate the effects of training communication skills during the performance of procedural skills (taking blood samples from a silicone model) in international and local students as part of their clinical practical medical training. METHODS: Study participants performed blood sampling on an arm prosthesis model (part-task trainer) before and after the communication skills training, focusing on accompanying communication with a simulation patient sitting next to the arm model. The pre- and post-evaluation video was assessed by two independent evaluators using a binary checklist, the Integrated Procedural Performance Instrument (IPPI) and global assessments of clinical professionalism in terms of procedural and communication performance. Linear models with mixed effects were used. Group differences regarding global competence levels were analysed with χ2-tests. RESULTS: International medical students did not perform as well as their local counterparts in the pre- and post-examinations. Both groups improved their performance significantly, whereby the international students improved more than their local counterparts in terms of their communication performance, assessed via binary checklist. Clinical professionalism evaluated via global assessments of procedural and communication performance highlights the intervention's impact insofar as no international student was assessed as clinically not competent after the training. CONCLUSIONS: Our results suggest that already a low-dose intervention can lead to improved communication skills in medical students performing procedural tasks and significantly increase their confidence in patient interaction.

[Promoting research competence in psychosocial medicine - A new curriculum for medical students]. / Wissenschaft verstehen und anwenden. Ein neues Curriculum für Medizinstudierende zur Entwicklung von Forschungskompetenz in der psychosozialen Medizin.

Promoting research competence in psychosocial medicine - A new curriculum for medical students Objectives: The objective of this study is the introduction and evaluation of a new graduate-students curriculum to enhance research competence in psychosocial medicine. Method: N = 57 students have participated in the curriculum to date. All participants completed questionnaires regarding teaching quality and pre-post changes in subjective research competence. Results: All items on teaching quality were scored significantly higher (p < 0.05) compared to data of three other comparable psychosocial seminars. In addition, a substantial increase in subjective research competence was found (p < 0.05). Conclusions: The presented curriculum provides an opportunity to strengthen research competence and evidence-based critical thinking of prospective physicians at an early stage. As a consequence of these encouraging results, the curriculum has been implemented permanently at the medical faculty in Heidelberg.

Cross-lagged analyses of the bidirectional relationship between depression and markers of chronic heart failure.

BACKGROUND: Depression is common in patients with chronic heart failure (CHF) and is a predictor of rehospitalization and mortality. However, the complex bidirectional relationships between these two conditions are barely understood. We investigated the course of depression and markers of CHF (New York Heart Association [NYHA] functional class, N-terminal-prohormone B-type natriuretic peptide [NT-proBNP], and left ventricular ejection fraction [LVEF]) in a longitudinal study over a period of 2 years, using three assessment points. METHODS: Data of n = 446 patients with documented CHF were analyzed using structural equation modeling. Specifically, a Bayesian cross-lagged structural equation model was applied. RESULTS: Our study revealed that an aggravation of depression predicted an increase in NYHA functional class (significant cross-lagged effect γh = 0.103, 95% confidence interval [CI] [0.017; 0.194]), whereas an increase in NYHA functional class did not predict an aggravation of depression (γd = 0.002 95% CI [-0.057; 0.194]). This association was found only for NYHA functional class and depression-not for NT-proBNP and LVEF. CONCLUSIONS: Experiencing depression and associated symptoms, such as lack of energy and fatigue, may lead to a further decrease of functional capacity, and consequently to a higher NYHA functional class in CHF patients. As NYHA functional class is associated with higher mortality, this may be a critical development for affected patients. Further studies are required to investigate whether or not this association could be an essential key that explains the pathway from depression to increased mortality in heart failure patients.

Impact of an educational workshop on psychiatrists' attitude towards psychosomatic medicine.

BACKGROUND: Although psychosomatic medicine is not recognised as a medical specialisation globally, it has proven useful for treating many disorders in Germany. This paper reports on the impact of an educational workshop as a tool for raising awareness about psychosomatic medicine among international psychiatrists. METHODS: Psychiatrists from eight different countries were educated on psychosomatic medicine and psychotherapy during a 90-min workshop using a video, a slide presentation and an innovative teaching format called 'speed coaching'. Learning outcomes were assessed by analysing questionnaires completed by the participants before and after the workshop. RESULTS: Half of the participants who initially rejected the notion that psychosomatic medicine should be a specialisation on its own changed their minds in favour for it to be a separate discipline (p = 0.125). Awareness about which diseases and patients psychosomatic doctors deal with was increased. The intent for treatment of patients with eating disorders by a psychosomatic physician quadrupled among the participants (p = 0.004). CONCLUSIONS: A brief educational intervention can influence psychiatrists' decisions to opt for approaches by doctors specialized in psychosomatics for certain disorders. Further studies may explore why psychiatrists agree or disagree that psychosomatic medicine should be a separate specialisation on its own.

Expressions of Individualization on the Internet and Social Media: Multigenerational Focus Group Study.

BACKGROUND: Growing individualization within the past decades has been described as a fundamental shift in society. Studies have reported how the digital age promotes new forms of individualism with self-tracking technologies and self-presentation in social networks. Potential harmful effects on the mental health of young adults have already been at the forefront of research. However, 2 questions that remain unanswered are how emotional experiences and expressions of self-relatedness differ among generations in their usage of the internet and social media, and if an increasing individualism can be observed by this. OBJECTIVE: The aim of this study is to examine whether the use of the internet and social media has led people to be more concerned about themselves than former generations. The potential consequences of mental and emotional distress among different age groups are analyzed. METHODS: A focus-group approach was chosen to study the following age groups: Baby Boomers (those born in 1950-1965), Generation X (those born in 1966-1980), and Digital Natives (those born in 1981-2000). We organized 6 focus groups with 36 participants who discussed their private usage of the internet and social media, different devices, platforms and functions, communication behavior, and self-tracking. We applied inductive category formation and followed the Standards for Reporting Qualitative Research (SRQR) checklist. RESULTS: We found differences in the 3 studied generations regarding the reasons for their use of the internet and social media, the effects of this use, personal feelings and experiences, expressions of self-relatedness, and social relationships. The Baby Boomers voiced a wish to stay autonomous while being in contact with their personal network. Generation X included enthusiastic members who appreciate self-tracking for curiosity and fascination, as well as people who felt fears about data surveillance. The Digital Natives reported a wish to optimize their own body by self-tracking while being faced with norms and expectations that were communicated via the internet and social media. CONCLUSIONS: All generations expressed self-relatedness, yet by different means. The Baby Boomers expressed less individualism than Generation X and the Digital Natives, who felt the highest strain due to social comparisons. However, all generations reported specific, potentially problematic consequences for their mental health. Age-specific coping strategies are necessary to promote a mentally healthy way of using the internet and social media.

Adherence to Established Treatment Guidelines Among Unguided Digital Interventions for Depression: Quality Evaluation of 28 Web-Based Programs and Mobile Apps.

BACKGROUND: Web-based interventions for depression have been widely tested for usability and functioning. However, the few studies that have addressed the therapeutic quality of these interventions have mainly focused on general aspects without consideration of specific quality factors related to particular treatment components. Clinicians and scientists are calling for standardized assessment criteria for web-based interventions to enable effective and trustworthy patient care. Therefore, an extensive evaluation of web-based interventions at the level of individual treatment components based on therapeutic guidelines and manuals is needed. OBJECTIVE: The objective of this study was to evaluate the quality of unguided web-based interventions for depression at the level of individual treatment components based on their adherence to current gold-standard treatment guidelines and manuals. METHODS: A comprehensive online search of popular app stores and search engines in January 2018 revealed 11 desktop programs and 17 smartphone apps that met the inclusion criteria. Programs and apps were included if they were available for German users, interactive, unguided, and targeted toward depression. All programs and apps were tested by three independent researchers following a standardized procedure with a predefined symptom trajectory. During the testing, all web-based interventions were rated with a standardized list of criteria based on treatment guidelines and manuals for depression. RESULTS: Overall interrater reliability for all raters was substantial with an intraclass correlation coefficient of 0.73 and Gwet AC1 value of 0.80. The main features of web-based interventions included mood tracking (24/28, 86%), psychoeducation (21/28, 75%), cognitive restructuring (21/28, 75%), crisis management (20/28, 71%), behavioral activation (19/29, 68%), and relaxation training (18/28, 64%). Overall, therapeutic meaningfulness was rated higher for desktop programs (mean 4.13, SD 1.17) than for smartphone apps (mean 2.92, SD 1.46). CONCLUSIONS: Although many exercises from manuals are included in web-based interventions, the necessary therapeutic depth of the interventions is often not reached, and risk management is frequently lacking. There is a need for further research targeting general principles for the development and evaluation of therapeutically sound web-based interventions for depression.

Mental Health Burden in Different Professions During the Final Stage of the COVID-19 Lockdown in China: Cross-sectional Survey Study.

BACKGROUND: COVID-19 resulted in considerable mental health burden in the Chinese general population and among health care workers at the beginning and peak of the pandemic. However, little is known about potentially vulnerable groups during the final stage of the lockdown. OBJECTIVE: The aim of this survey study was to assess the mental health burden of different professions in China in order to find vulnerable groups, possible influencing factors, and successful ways of coping during the last 4 weeks of the lockdown in Hubei Province. METHODS: A cross-sectional online survey asked participants about current residence, daily working hours, exposure to COVID-19 at work, and media preferences. We used a shortened version of the Depression, Anxiety and Stress Scale (DASS-21) to assess mental health. Further assessments included perceived stress (Simplified Chinese version of the 14-item Perceived Stress Scale), coping strategies for all participants, and specific stressors for health care workers. We followed the reporting guidelines of the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) statement for observational studies. RESULTS: The sample (N=687) consisted of 158 doctors, 221 nurses, 24 other medical staff, 43 students, 60 teachers/government staff, 135 economy staff, 26 workers/farmers, and 20 professions designated under the "other" category. We found increased depression (n=123, 17.9%), anxiety (n=208, 30.3%), and stress (n=94, 13.7%) in our sample. Professions that were vulnerable to depression were other medical staff and students. Doctors, nurses, and students were vulnerable to anxiety; and other medical staff, students, and economy staff were vulnerable to stress. Coping strategies were reduced to three factors: active, mental, and emotional. Being female and emotional coping were independently associated with depression, anxiety, or stress. Applying active coping strategies showed lower odds for anxiety while mental coping strategies showed lower odds for depression, anxiety, and stress. Age, being inside a lockdown area, exposure to COVID-19 at work, and having a high workload (8-12 hours per day) were not associated with depression, anxiety, or stress. WeChat was the preferred way of staying informed across all groups. CONCLUSIONS: By the end of the lockdown, a considerable part of the Chinese population showed increased levels of depression and anxiety. Students and other medical staff were the most affected, while economy staff were highly stressed. Doctors and nurses need support regarding potential anxiety disorders. Future work should focus on longitudinal results of the pandemic and develop targeted preventive measures.

Exploring early interprofessional socialization: a pilot study of student's experiences in medical history taking.

Traditional hierarchies and structures in healthcare, as well as traditional professional socialization practices, continue to create barriers to effective interprofessional collaboration. Nevertheless, some studies indicate that early socialization with other health professionals can build bridges and improve understanding of each other's roles and contributions to patient care. This pilot study aimed to gain insights into the nursing and medical students' experiences of interprofessional medical history taking during a collective learning activity. A descriptive case study was conducted using modified interviews based on the speed-dating (SD) technique to explore participants' reasons for the choice of profession (SD1) and experiences of interprofessional history taking (SD2). Data were digitally captured using audio-recordings. An inductive-deductive approach to qualitative content analysis of transcribed responses was undertaken. Eighteen students (medicine n = 6; nursing n = 12) participated. Two main categories with sub-themes emerged from the inductive SD1 analysis: (a) reasons for choosing a career and (b) knowledge about professions. The SD2 deductive analysis identified three major categories with sub-themes: (a) breaking down barriers, (b) interprofessional role learning - interprofessional collaboration and (c) dual-identity development. Our findings showed that early interprofessional socialization of students supported their learning about the complementary roles of doctors and nurses and enabled them to gain early experiences of interprofessional teamwork.

Delirium: Medical Students' Knowledge and Effectiveness of Different Teaching Methods.

OBJECTIVE: Medical schools are often blamed for inadequately training doctors on delirium. This study assesses the knowledge of medical students regarding delirium and evaluates different teaching methods for comparing learning outcomes. METHODS: A video, a handout, and a video+handout were used as three different teaching methods. Students were randomly assigned to three groups and pre- and postintervention knowledge gains were compared. Interventions were held between 2015 and 2018 at the University of Heidelberg Medical School in Germany. Seventy-eight (video intervention 33; handout 26; video+handout 19) sixth-year medical students participated. Participants learned about delirium with the help of a video, a handout, and both a video+handout at the start of one-hour lectures dedicated to teaching about delirium. Pre- and postintervention questionnaires, comprising five multiple-choice questions and a self-estimated grade of knowledge about delirium, were used. Variables calculated were objective and subjective knowledge, recall, and accuracy of self-assessment. Microsoft Excel and analysis of covariance were used to analyze data. RESULTS: Knowledge gains for all interventions were large (d>0.8) irrespective of gender. Post hoc comparison showed video and video+handout methods were more effective with high recall for video (92.8%). Students rated their knowledge as satisfactory, although they scored 11.4 out of 20. Preintervention knowledge level was correctly estimated by 31% of students, and postintervention by 40.3% students. CONCLUSION: Teaching about delirium to medical students with a video resulted in better knowledge transfer and recall. Most medical students, particularly men, overestimated their knowledge about delirium.

Stress and stressors of medical student near-peer tutors during courses: a psychophysiological mixed methods study.

BACKGROUND: Structured peer-led tutorial courses are widespread and indispensable teaching methods that relieve teaching staff and contribute to the development of students' competencies. Nevertheless, despite high general stress levels in medical students and associated increases in psychopathology, specific knowledge of peer tutors' additional burdens is very limited. METHODS: Sixty student near-peer tutors from two structured peer-teaching programmes volunteered to participate. On multiple occasions in three different course sessions, we assessed tutors' subjective stress, affective state, heart rate variability, and salivary cortisol. Additionally, tutors named everyday and course-specific stressors, which were evaluated by means of content analyses. RESULTS: The study participation rate was high (63% of all active tutors). The participating tutors are socially well adapted and resilient individuals. They report a variety of stressors such as time pressure, participant characteristics, teacher role demands, and study requirements, but nevertheless display only moderate psychological and physiological stress that decreases over sessions. Tutors' negative affect in sessions is low; their positive affect is consistently high for senior as well as novice tutors. Tutors rate their courses' quality as high and quickly recover after sessions. CONCLUSIONS: Tutors successfully cope with teaching-associated and everyday life demands. The results corroborate the viability and success of current peer-teaching programmes from the tutors' perspective. This study is the first to comprehensively quantify tutors' stress and describe frequent stressors, thus contributing to the development of better peer teaching programmes and tutor qualification training.

A communication-focused curriculum for dental students - an experiential training approach.

BACKGROUND: Successful interaction and communication with patients is as vital for dentists as it is for physicians. Therefore, the aim of this study was the development and evaluation of an interactive, experiential training curriculum with an emphasis on communication for dual degree seekers of medicine and dentistry. METHODS: A pre-clinical course with an emphasis in physician/dentist-patient communication and interaction was adapted by a team of subject experts based largely on the propositions of Experiential Learning Theory. After attending the course, dental students (N = 81) rated the course on a Likert- style scale and answered two open questions. RESULTS: Students found the interactive course curriculum to be very helpful and vital. Many students reported that their initial interest in the course was mainly because it is a dual degree requirement, but later on rated the course as highly important in terms of later physician/dentist-patient interaction. One aspect of the curriculum course participants regarded as very important, yet neglected during dental studies, was (self-) perception. CONCLUSION: In the view of dental students, the rigorous structure of the pre-clinical dental curriculum does not allow for time spent on topics such as (self-) perception and awareness, but training one's ability to self-reflect and think critically about one's own actions, conduct or position can aid with advanced medical and dental studies and practices later on. Experiential courses with an emphasis on patient-physician/dentist communication should be offered early on during pre-clinical medical and dental studies as a regular part of the curriculum.

Anchoring interprofessional education in undergraduate curricula: The Heidelberg story.

The ability of health professionals to collaborate effectively has significant potential impact on patient safety and quality-care outcomes, especially given the increasingly complex and dynamic clinical practice environments of today. Educators of the health professions are faced with an immediate challenge to adapt curricula and traditional teaching methods to ensure graduates are equipped with the necessary interprofessional competencies and (inter)professional values for their future practice. The World Health Organization's "Framework for action in interprofessional education (IPE) and collaborative practice" promotes IPE as a key strategy to enhance patient outcomes by preparing a "collaborative practice-ready health workforce." Logistical and attitudinal barriers can hinder integration of IPE into curricula. Lessons learned through the implementation of a planned change to establish four interprofessional seminars (team communication, medical error communication, healthcare English, and small business management) at Heidelberg University Medical Faculty, Germany, are described. A key factor in successfully anchoring IPE seminars in the undergraduate curricula was the structured approach drawing on change management concepts.

The Effects of Mitral Valve Repair on Memory Performance, Executive Function, and Psychological Measures in Patients With Heart Failure.

OBJECTIVES: Heart failure (HF) is a prevalent disease that remains costly and associated with a high mortality rate. HF is also associated with poor neurocognitive functioning. For the treatment for HF patients with severe mitral regurgitation, the MitraClip device has emerged as a promising interventional tool that reduces the mitral valve leakage and thus increases cardiac output. Currently, there is only limited knowledge on changes in cognitive and psychosocial functioning before and after the MitraClip intervention. METHODS: Cognitive function (memory and executive function) and psychosocial measures (depression, anxiety, and quality of life) were assessed before and after the MitraClip intervention in 24 HF patients and 23 healthy participants (comparison group). RESULTS: MitraClip intervention in HF patients was followed by improvements in figural long-term memory (p = .003) and executive function (planning ability, p < .001) relative to the comparison group. In addition, the intervention resulted in a significant improvement in depression (p = .002), anxiety (p = .003) and quality of life scores (physical p = .017, mental p = .013) as well as improved 6-minute walk test results over time (p = .002). CONCLUSIONS: The presented data provide evidence of a significant improvement in memory and executive function as well as in depression, anxiety, and quality of life scores in patients with chronic HF after MitraClip intervention. Further research is needed to shed light on the long-term development of cognitive function, psychosocial well-being, and clinical parameters after MitraClip intervention and how these factors depend on one another.

[Competence-based catalogue of learning objectives for conducting medical consultations]. / Kompetenzbasierter Lernzielkatalog ¼Ärztliche Gesprächsführung« .

ISSUE: In 2012 the German medical licensure regulations (Approbationsordnung) made teaching and assessing the conduction of medical consultations a mandatory part of medical education. A catalogue of learning objectives (LO) based on existing references was developed to assist medical schools in meeting this requirement. METHODS: A body of relevant material was compiled using literature research and surveying experts. Then, in a multiphase Delphi process, this was evaluated and condensed by an interdisciplinary working group in dialogue with external (clinical) experts. Competence levels and examples of clinical application were assigned to enhance implementation. The catalogue was revised by the medical faculties, professional associations and the BVMD. RESULTS: This learning catalogue comprised 116 learning objectives for the specific skills necessary to conducting medical consultations as well as exemplary application contexts. The catalogue proved to be practical in terms of developing curricula and networking at medical schools. DISCUSSION: This catalogue of learning objectives can serve as the basis for developing a sample communication curriculum for use by medical faculties.

Cost-effectiveness of peer role play and standardized patients in undergraduate communication training.

BACKGROUND: The few studies directly comparing the methodological approach of peer role play (RP) and standardized patients (SP) for the delivery of communication skills all suggest that both methods are effective. In this study we calculated the costs of both methods (given comparable outcomes) and are the first to generate a differential cost-effectiveness analysis of both methods. METHODS: Medical students in their prefinal year were randomly assigned to one of two groups receiving communication training in Pediatrics either with RP (N = 34) or 19 individually trained SP (N = 35). In an OSCE with standardized patients using the Calgary-Cambridge Referenced Observation Guide both groups achieved comparable high scores (results published). In this study, corresponding costs were assessed as man-hours resulting from hours of work of SP and tutors. A cost-effectiveness analysis was performed. RESULTS: Cost-effectiveness analysis revealed a major advantage for RP as compared to SP (112 vs. 172 man hours; cost effectiveness ratio .74 vs. .45) at comparable performance levels after training with both methods. CONCLUSIONS: While both peer role play and training with standardized patients have their value in medical curricula, RP has a major advantage in terms of cost-effectiveness. This could be taken into account in future decisions.
