Technical development in cardiac CT: current standards and future improvements—a narrative review

2020

Non-invasive depiction of coronary arteries has been a great challenge for imaging specialists since the introduction of computed tomography (CT). Technological development together with improvements in spatial, temporal, and contrast resolution, progressively allowed implementation of the current clinical role of the CT assessment of coronary arteries. Several technological evolutions including hardware and software solutions of CT scanners have been developed to improve spatial and temporal resolution. The main challenges of cardiac computed tomography (CCT) are currently plaque characterization, functional assessment of stenosis and radiation dose reduction. In this review, we will discu…

Untersuchungen zur Aktivit�tskinetik des Isoenzymes CK-MB im Serum nach Myokardinfarkt

1978

We investigated the activity kinetics of CK-total and CK-MB in 83 patients with proven myocardial infarctions. Serial serum samples were taken at intervals of 2--6 h. The activity of isoenzym CK-MB was determined by means of the immunological inhibition method. CK-MB activity was determined in all patients. The mean peak activity of CK-MB was 65 U/l (range: 9-241 U/l). At the time of peak CK-MB activity the mean percentage CK-MB activity was 13.2% (range: 3.4--21.7%). The CK-MB activity reached its peak at 17.4 h (range: 3.0--32.5 h) after the onset of retrosternal pain. This is 1.4 h after peak CK-total activity. The mean disappearance rate constant for CK-MB (n = 31) was found to be 9.3 X…

Primary ciliary dyskinesia assessment by means of optical flow analysis of phase-contrast microscopy images

2014

Primary ciliary dyskinesia implies cilia with defective or total absence of motility, which may result in sinusitis, chronic bronchitis, bronchiectasis and male infertility. Diagnosis can be difficult and is based on an abnormal ciliary beat frequency (CBF) and beat pattern. In this paper, we present a method to determine CBF of isolated cells through the analysis of phase-contrast microscopy images, estimating cilia motion by means of an optical flow algorithm. After having analyzed 28 image sequences (14 with a normal beat pattern and 14 with a dyskinetic pattern), the normal group presented a CBF of 5.2 +/- 1.6 Hz, while the dyskinetic patients presented a 1.9 +/- 0.9 Hz CBF. The cutoff …

Systematic review of psychotherapeutic treatments for “minor” personality disorders

2011

IntroductionAmong personality disorders (PDs), antisocial and borderline personality disorder are well-studied. However, the remaining PDs (in the following called “minor PDs”) pose major problems in everyday-health care settings. People affected often present with additional axis-l disorders such as substance-related, mood or anxiety disorders, and are among those most difficult to treat.ObjectivesTo systematically review the current evidence of psychotherapeutic treatments for “minor” personality disordersMethodsIn the context of Cochrane Collaboration reviews for Cluster A, B and C PDs, exhaustive literature searches were done to identify the current RCT evidence for PD treatments. The e…

Impact of the COVID-19 pandemic on hospitalizations for acute coronary syndromes: a multinational study

2021

Abstract Background COVID-19 has challenged the health system organization requiring a fast reorganization of diagnostic/therapeutic pathways for patients affected by time-dependent diseases such as acute coronary syndromes (ACS). Aim To describe ACS hospitalizations, management, and complication rate before and after the COVID-19 pandemic was declared. Design Ecological retrospective study. Methods: We analyzed aggregated epidemiological data of all patients > 18 years old admitted for ACS in twenty-nine hub cardiac centers from 17 Countries across 4 continents, from December 1st, 2019 to April 15th, 2020. Data from December 2018 to April 2019 were used as historical period. Results…

Cardiopulmonary exercise testing in COVID-19 patients at 3 months follow-up

2021

Abstract Background Long-term effects of Coronavirus Disease of 2019 (COVID-19) and their sustainability are of the utmost relevance. For the chronic phase, the main concerns are the development of pulmonary interstitial disease and/or lingering cardiovascular involvement. How to intercept, assess, and treat these patients with long-term consequences of COVID-19 remains uncertain. Purpose We aimed to determine: 1) functional capacity of COVID-19 survivors by cardiopulmonary exercise testing (CPET); 2) those characteristics associated with CPET performance; 3) safety and tolerability of CPET. Methods We prospectively enrolled consecutive patients with laboratory-confirmed COVID-19 discharged…

P145 Inflammatory Bowel Disease patients requiring surgery can be treated in referral centres regardless of the COVID-19 status of the hospital: resu…

2021

Abstract Background Little is known regarding the outcomes of inflammatory bowel disease (IBD) patients who required surgery during the outbreak of Coronavirus disease 19 (COVID-19). This study aimed to compare outcomes of IBD patients undergoing surgery in COVID-19-treatment and COVID-19-free hospitals. Methods Retrospective study involving patients undergoing IBD surgery in seven centres (six COVID-19-treatment hubs and one COVID-free hospital) across 5 European countries during the period of highest reduction of elective activity due to the first peak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections. Predictive variables of the risk of moderate-to-severe postope…

Attitudes towards learning professional ethics in undergraduate physiotherapy students: A STROBE compliant cross-sectional study.

2020

BACKGROUND: Ethics is a key competence to be acquired by physiotherapy students to ensure quality care. However, students may not be aware of the importance of ethics for the development of their clinical practice, in the same way that their attitudes towards Professional Ethics are unknown within their curriculum. OBJECTIVES: The aim of this study was to identify the attitudes towards learning Professional Ethics among undergraduate students of Physiotherapy Degree and compare the attitude between the educational years. DESIGN: A cross-sectional study was carried out. SETTINGS: Physiotherapy Degree at the University of Valencia, Spain. PARTICIPANTS: In the study 340 physiotherapy students …
