From an evidence-based perspective, cardiopulmonary exercise testing (CPX) is a well-supported assessment technique in both the United States (US) and Europe. The combination of standard exercise testing (ET) (ie, progressive exercise provocation in association with serial electrocardiograms [ECG], hemodynamics, oxygen saturation, and subjective symptoms) and measurement of ventilatory gas exchange amounts to a superior method to: 1) accurately quantify cardiorespiratory fitness (CRF), 2) delineate the physiologic system(s) underlying exercise responses, which can be applied as a means to identify the exercise-limiting pathophysiologic mechanism(s) and/or performance differences, and 3) formulate function-based prognostic stratification. Cardiopulmonary ET certainly carries an additional cost as well as competency requirements and is not an essential component of evaluation in all patient populations. However, there are several conditions of confirmed, suspected, or unknown etiology where the data gained from this form of ET is highly valuable in terms of clinical decision making

Objective: In myocardial perfusion single-photon emission computed tomography (SPECT), abdominal activity often interferes with the evaluation of perfusion in the inferior wall, especially after pharmacological stress. In this randomized study, we examined the effect of carbonated water intake versus still water intake on the quality of images obtained during myocardial perfusion images (MPI) studies. Methods: A total of 467 MIBI studies were randomized into a carbonated water group and a water group. The presence of intestinal activity adjacent to the inferior wall was evaluated by two observers. Furthermore, a semiquantitative analysis was performed in the adenosine subgroup,using a count ratio of the inferior myocardial wall and adjacent abdominal activity. Results: The need for repeated SPECT in the adenosine studies was 5.3 % in the carbonated water group versus 19.4 % in the still water group (p = 0.019). The inferior wall-to-abdomen count ratio was significantly higher in the carbonated water group compared to the still water group (2.11 ± 1.00 vs. 1.72 ± 0.73, p\0.001). The effect of carbonated water during rest and after exercise was not significant. Conclusions: This randomized study showed that carbonated water significantly reduced the interference of extra-cardiac activity in adenosine SPECT MPI.

Tijdens een afstudeeronderzoek is onderzoek gedaan naar MRI-compatible pacemakers via literatuuronderzoek en interviews. Uit het onderzoek blijft dat er een tweetal aspecten zijn waar men rekening mee dient te houden bij een MRI-compatible pacemaker. Het eerste aspect heeft betrekking op de scanparameters. De belangrijkste hiervan zijn de SAR en de Gradiënt Slew Rate. De fabrikanten hebben voor elk type pacemakersysteem en leads een maximale SAR en Gradiënt Slew Rate opgesteld. Het tweede aspect heeft betrekking op de bewaking van de patiënt tijdens het MRI-onderzoek. Voorafgaand aan het onderzoek moet de pacemaker in de ‘MRI-stand’ worden gezet. Daarnaast dient de patiënt tijdens het MRI-onderzoek ten alle tijden bewaakt te worden door middel van een MRI-compatible ECG en saturatiemeter

This systematic review aims to get insight into the feasibility of cardiopulmonary exercise testing (CPET) in patients with cancer prior to a physical exercise programme. We will focus on quality (defined as the adherence to international guidelines for methods of CPET) and safety of CPET. Furthermore, we compare the peak oxygen uptake (V̇O2peak) values of patients with cancer with reference values for healthy persons to put these values into a clinical perspective. A computer aided search with ‘cardiopulmonary exercise testing’ and ‘cancer’ using MEDLINE, EMBASE, Pedro, CINAHL® and SPORTDiscus™ was carried out. We included studies in which CPET with continuous gas exchange analysis has been performed prior to a physical exercise programme in adults with cancer. Twenty studies describing 1158 patients were eligible. Reported adherence to international recommendations for CPET varied per item. In most studies, the methods of CPET were not reported in detail. Adverse events occurred in 1% of patients. The percentage V̇O2peak of reference values for healthy persons varied between 65% and 89% for tests before treatment, between 74% and 96% for tests during treatment and between 52% and 117% for tests after treatment. Our results suggest that CPET is feasible and seems to be safe for patients with cancer prior to a physical exercise programme. We recommend that standard reporting and quality guidelines should be followed for CPET methods. The decreased V̇O2peak values of patients with cancer indicate that physical exercise should be implemented in their standard care.

To prepare medical students appropriately for the management of toxicological emergencies, we have developed a simulation-based medical education (SBME) training in acute clinical toxicology. Our aim is to report on the feasibility, evaluation and lessons learned of this training. Since 2019, each year approximately 180 fifth-year medical students are invited to participate in the SBME training. The training consists of an interactive lecture and two SBME stations. For each station, a team of students had to perform the primary assessment and management of an intoxicated patient. After the training, the students completed a questionnaire about their experiences and confidence in clinical toxicology. Overall, the vast majority of students agreed that the training provided a fun, interactive and stimulating way to teach about clinical toxicology. Additionally, they felt more confident regarding their skills in this area. Our pilot study shows that SBME training was well-evaluated and feasible over a longer period.

BACKGROUND:Many patients visiting physiotherapists for musculoskeletal disorders face psychosocial challenges which may form a large barrier to recover. There are only a limited number of evidence based psychosocial therapies, but they are mainly based on breathing exercises. OBJECTIVE: to study which respiration frequency would lead to the highest relaxation, reflected in vagal tone derived from the heart rate variability (HRV) in healthy subjects. METHODS: A randomized controlled cross sectional study was performed. Respiration cycles of four, five, six, seven and eight breaths per minute (BPM) were delivered in randomized order for two minutes each. HRV metrics were measured during the sessions with electrocardiogram (ECG). Repeated Measures ANOVA’s were performed to analyze differences between breathing frequencies. RESULTS: 100 healthy volunteers were included (40 male). Standard Deviation of inter beat intervals (SDNN) values were significantly highest at 5 BPM, whereas the Root Mean Square of Successive Differences (RMSSD) values appeared highest at 7 breaths per minute (p< 0.01). High Frequency (HF) power was lowest at 4 BPM, whereas Low Frequency (LF) power was not significantly influenced by respiration frequency. CONCLUSIONS: Breathing at a frequency of 5 to 7 breaths per minute leads to highest HRV values, but there is no single respiration ratio that maximizes all metrics. Physiotherapists may use five to seven BPM as guidance to determine ideal breathing frequencies

Lectorale rede bij de aanvaarding van het ambt van lector Medische Technologie Medische Technologie is een zeer breed begrip dat reikt van infuuspompen tot operatierobots tot lineaire versnellers, et cetera. In het vorige hoofdstuk is al uit de doeken gedaan waar het lectoraat Medische Technologie zich specifiek op richt: medische beeldvorming, radiotherapie en ICT in de zorg. Dat is bij elkaar een zeer breed vakgebied waarvan het lectoraat niet alle facetten kan bestrijken. Daarom richt het lectoraat zich op ontwikkelingen op die terreinen die belangrijke veranderingen in het werkproces teweeg kunnen brengen. Dat zijn de onderwerpen die van belang zijn voor de toekomstige Zorgprofessional 2.0. Hieronder worden de verschillende vakgebieden nader geïntroduceerd en er worden een aantal voor de Zorgprofessional 2.0 belangrijke historische trends beschreven. Samenvattend kan gesteld worden dat het lectoraat Medische Technologie zich heeft ontwikkeld van een specialistisch op radiotherapie gericht lectoraat, naar een breder op medische beeldvorming, radiotherapie, ICT in de zorg en eHealth georiënteerd lectoraat dat op diverse, met name gezondheidszorggerelateerde, terreinen een bijdrage levert aan de opleidingen van Hogeschool Inholland. De bijdrage van het lectoraat Medische Technologie heeft daarbij als doel afstudeerders van diverse studierichtingen op te leiden tot wat in deze rede wordt aangeduid met Zorgprofessional 2.0. Hiermee wordt in deze rede een beroepsbeoefenaar bedoeld die openstaat voor (ICT/technische) innovatie, die zorgconsumenten daarover kan adviseren en die innovatie in de beroepspraktijk weet te implementeren. Praktijkgericht onderzoek speelt daarbij een centrale rol: het draagt bij aan de onderzoekende blik van de Zorgprofessional 2.0, aan het up-to-date houden van de kennis van docenten en studenten en aan de verbinding met het werkveld.
