Employing Simulated Participants to Develop Communication Skills in Medical Education: A Systematic Review.

Simulated participants (SPs) are often employed to teach communication skills in medical education. Although there is a large number of qualitative and/or noncomparative studies in this field, there is no current evidence for the effectiveness of this teaching method based on quantitative comparative meta-data. The aim of this review was to evaluate the effectiveness of SP-based teaching on patient-centered communication skills in medical education compared with traditional teaching formats such as lecture or peer role play focusing on quantitative and comparative data.

How to: Success factors for the implementation and establishment of the "longitudinal curriculum" on communicative competencies at the Medical Faculty Mannheim.

Communicative competencies are of great importance to the medical profession, hence the teaching of them has been continuously expanded in recent years at many German medical schools. While individual courses on communicative competencies have already been established in the curricula, there remains, in part, a lack of longitudinal anchoring over the entire course of medical study. In 2008 the Medical Faculty Mannheim began implementing a longitudinal curriculum for communicative competencies.

Authentic SP-based teaching in spite of COVID-19 - is that possible?

Medical conversation plays a central role in disease management and therapy. In teaching, standardized patients (SPs) are increasingly being used to present conversation situations with students and provide feedback afterwards. In order to maintain this teaching concept under pandemic conditions, a digital model was developed that should offer both high security and high authenticity.

Automated Noninvasive Central Blood Pressure Measurements by Oscillometric Radial Pulse Wave Analysis: Results of the MEASURE-cBP Validation Studies.

Background: Central blood pressure becomes increasingly accepted as an important diagnostic and therapeutic parameter. Accuracy of widespread applanation tonometry can be affected by calibration and operator training. To overcome this, we aimed to evaluate novel VascAssist 2 using automated oscillometric radial pulse wave analysis and a refined multi-compartment model of the arterial tree.

Multiple coupled resonances in the human vascular tree: refining the Westerhof model of the arterial system.

The human arterial vascular tree can be described by multicompartment models using electrical components. First introduced in the 1960s by Noordergraaf and Westerhof, these hardware-based approaches required several simplifications. We were able to remove the restrictions using modern software simulation tools and improve overall model quality considerably.

Comparison of electrical velocimetry and cardiac magnetic resonance imaging for the non-invasive determination of cardiac output.

A novel algorithm of impedance cardiography referred to as electrical velocimetry (EV) has been introduced for non-invasive determination of cardiac output (CO). Previous validation studies yielded diverging results and no comparison with the non-invasive gold standard cardiac magnetic resonance imaging (CMR) has been performed. We therefore aimed to prospectively assess the accuracy and reproducibility of EV compared to CMR.

Influence of bag volume on reproducibility of inert gas rebreathing pulmonary blood flow measurements in patients with pulmonary diseases.

Purpose: Non-invasive inert gas rebreathing (IGR) has shown promising results in the determination of pulmonary blood flow. The volume of the rebreathing bag (V bag) is proposed by the system. However, elderly patients or those with severe pulmonary disease may be unable to rebreathe this volume entirely.

Is arterial pulse contour analysis using Nexfin a new option in the noninvasive measurement of cardiac output?--A pilot study.

Objectives: A growing interest in monitoring cardiac output (CO) noninvasively has emerged; however, its determination has been difficult using the standard approaches. The aim of this study was to evaluate the accuracy and precision of pulse contour analysis (PCA) compared with cardiac magnetic resonance imaging (CMR).

Design: A single-center prospective study.

A comparative evaluation of electrical velocimetry and inert gas rebreathing for the non-invasive assessment of cardiac output.

Background: When assessing the function of the cardiovascular system, cardiac output (CO) is a substantial parameter. For its determination, numerous non-invasive techniques have been proposed in the recent years including inert gas rebreathing (IGR) and impedance cardiography (ICG). The aim of our study was to evaluate whether a novel ICG algorithm (electrical velocimetry) and IGR can be used interchangeably in the clinical setting.

ESC Working Group on Valvular Heart Disease Position Paper: assessing the risk of interventions in patients with valvular heart disease.

Aims: Risk scores provide an important contribution to clinical decision-making, but their validity has been questioned in patients with valvular heart disease (VHD), since current scores have been mainly derived and validated in adults undergoing coronary bypass surgery. The Working Group on Valvular Heart Disease of the European Society of Cardiology reviewed the performance of currently available scores when applied to VHD, in order to guide clinical practice and future development of new scores.

Methods And Results: The most widely used risk scores (EuroSCORE, STS, and Ambler score) were reviewed, analysing variables included and their predictive ability when applied to patients with VHD.

The impact of pulmonary disease on noninvasive measurement of cardiac output by the inert gas rebreathing method.

Cardiac output (CO) is an important parameter for diagnosis and therapy of heart diseases, but it is still difficult to determine. Innocor, a novel noninvasive inert gas rebreathing (IGR) system, has shown promising results. However, the impact of pulmonary diseases on IGR remains unclear.

A novel noninvasive ultrasonic cardiac output monitor: comparison with cardiac magnetic resonance.

Background: USCOM, a novel continuous wave Doppler (CWD) device, has been introduced for noninvasive determination of cardiac output (CO). The present study aimed to compare the accuracy and reproducibility of the new device, using cardiovascular magnetic resonance imaging (CMR) as the noninvasive gold standard.

Methods And Results: The CO of 56 consecutive patients was prospectively determined by CWD either before or after CMR imaging.

Noninvasive determination of cardiac output by the inert-gas-rebreathing method--comparison with cardiovascular magnetic resonance imaging.

Background: An easy, noninvasive and accurate technique for measuring cardiac output (CO) would be desirable for the diagnosis and therapy of cardiac diseases. Innocor, a novel inert-gas-rebreathing (IGR) system, has shown promising results in smaller studies. An extensive evaluation in a larger, less homogeneous patient collective is lacking.

Association of NT-proBNP with severity of heart valve disease in a medical patient population presenting with acute dyspnea or peripheral edema.

Background And Aim Of The Study: The study aim was to perform a comprehensive evaluation of the association between N-terminal pro B-type natriuretic peptide (NT-proBNP) and the severity of heart valve diseases in a typical clinical population presenting with acute dyspnea or peripheral edema.

Methods: Among 401 eligible patients, 210 demonstrated evaluable complete echocardiographic examinations. Plasma levels of NT-proBNP were measured after the initial clinical evaluation.

Percutaneous treatment of a coronary aneurysm by stent graft and drug-eluting stent implantation: a potential method to reduce stent graft restenosis.

Coronary artery aneurysms (CAAs) can occur congenitally or secondary to specific disorders such as Kawasaki disease or atherosclerosis. Apart from a surgical approach, CAA can be treated by coronary stent graft (CSG) implantation. However, restenosis is frequent after CSG placement, precluding a wider use of this technique.

Non-invasive determination of cardiac output: comparison of a novel CW Doppler ultrasonic technique and inert gas rebreathing.

Background: Cardiac Output (CO) is an important parameter in the diagnosis and therapy of heart diseases. Inert gas rebreathing (IGR) and continuous wave Doppler ultrasound (CWD) are among the most promising newer techniques aiming at a non-invasive, point of care measurement of CO. A direct comparison of the two methods has not yet been carried out.

Modification of the Harris-Benedict equation to predict the energy requirements of critically ill patients during mild therapeutic hypothermia.

Unlabelled: The aim of the present study was the comparison of calculated and measured values of the energy expenditure of critically ill patients during the different phases of therapeutic mild hypothermia.

Patients And Methods: Five patients (mean age 40.6 years, range 23 to 68 years, 2 females) suffering from severe acute cerebral injuries who underwent mild hypothermia were prospectively included into the study.

Systemic and local levels of fetuin-A in calcific aortic valve stenosis.

Calcific aortic valve stenosis, the most frequent heart valve disorder in developed countries, is an actively regulated process with similarities to bone formation. Fetuin-A has recently been identified as a potent circulating inhibitor of calcification. While several studies involving patients with end-stage renal disease have shown an association between low serum fetuin-A and cardiovascular calcification, nothing is known about fetuin-A serum levels in non-renal patients with calcific aortic valve stenosis.

Coronary artery disease in takotsubo cardiomyopathy.

Background: Significant coronary artery disease (CAD) is generally considered as an exclusion criterion for the diagnosis of takotsubo cardiomyopathy (TC). However, this may not be justified in all cases, because TC and CAD may coincide.

Methods And Results: Among 821 consecutive patients who underwent urgent left heart catheterization for suspected acute coronary syndrome between December 2004 and August 2006 those with a final diagnosis of TC who also had a stenotic lesion (diameter stenosis on quantitative coronary angiography >50% and <75%) of the left anterior descending artery were evaluated.
