Digital Acquisition and Processing of Video Angiocardiograms

1986

Angiocardiographic diagnosis is still mainly based on the visual assessment of radiographic projection images recorded on photographic film. Considerable amounts of contrast material have to be selectively injected into the circulation in order to make the regions of diagnostic relevance visible in the superposition of the shadows of tissue and bone structures displayed in these transmission images. In addition, selective angiocardiography requires exact positioning of the catheter, a time-consuming procedure which is not without risk. The processing of the angiographie films obtained is difficult to maintain at a constant high quality level, and this introduces an disadvantageous delay bet…

Real and simulated endoscopy of neurosurgical approaches in an anatomical model

1997

Endoscopy simulation is a new visualisation technique which can be used to visualise patient anatomy as seen through endoscopes. In the following, we describe the application of simulated endoscopy to neurosurgical endoscopic approaches. We assess different aspects of virtual images and their influence on the final result, as judged by clinicians. One of these aspects is the projective geometry which is used to render the 3D images. Rendering using stereographic projection leads to more realistic endoscopic views than perspective projection.

Defining the Field of Behavioral Medicine: A Collaborative Endeavor.

2017

Purpose: To respond to comments on our proposal for an update of the definition and scope of behavioral medicine. Methods: We identify common themes in the comments and provide a response. Results: We discuss the relationship of behavioral medicine to other disciplines and fields, the scope of behavioral medicine, and issues related to the application of behavioral medicine. Conclusion: Based on the comments of our esteemed colleagues and our reflection on those comments, we now offer the following refined definition and scope of behavioral medicine. ‘Behavioral medicine can be defined as the field characterized by the collaboration among multiple disciplines concerned with the development …

Proposal for an Update of the Definition and Scope of Behavioral Medicine

2017

Purpose: We aim to provide an update of the definition and scope of behavioral medicine in the Charter of ISBM, as the present version was developed more than 25 years ago. Methods: We identify issues which need clarification or updating. This leads us to propose an update of the definition and scope of behavioral medicine. Results: Issues in need of clarification or updating include the scope of behavioral medicine (biobehavioral mechanisms, clinical diagnosis and intervention, and prevention and health promotion); research as an essential characteristic of all three areas of behavioral medicine; the application of behavioral medicine; the terminology of behavioral medicine as a multidisci…

Sir, We read with interest the scientific commentary by Hornberger and Bertoux (2015) on our study on the specificity of prefrontal cortex subregions for strategy use, verbal initiation and suppression (Robinson et al. , 2015). We administered Section 1 and 2 of the Hayling sentence completion task (Burgess and Shallice, 1997) to a large group of frontal and posterior patients. Section 1, assessing verbal initiation, requires the subject to complete sentences with an appropriate word (e.g. ‘ The captain stayed with the sinking …’ could be completed by saying ‘ ship ’). Section 2, assessing inhibition/suppression, requires the completion of sentences with an unconnected word (e.g. ‘ London i…

Social media use to improve communication on children and adolescent’s health: the role of the Italian Paediatric Society influencers

2021

Abstract Background Fake news on children’s and adolescent health are spreading. Internet availability and decreasing costs of media devices are contributing to an easy access to technology by families. Public health organizations are working to contrast misinformation and promote scientific communication. In this context, a new form of communication is emerging social media influencers. Aim of this study is to evaluate the role of paediatric influencers (PI) in communicating information about children and adolescents’ health. Materials and methods A group of PI was enrolled from December 2019 to January 2020 by a scientific commission nominated by the Italian Paediatric Society (SIP). PI w…

Neprilysin inhibition, endorphin dynamics, and early symptomatic improvement in heart failure: a pilot study

2020

Altres ajuts: This work was supported in part by Fundació La Marató de TV3 (201516-10, 201502-30), Societat Catalana de Cardiologia, "la Caixa" Banking Foundation. Altres ajuts: PERIS/SLT002-16-00234 Sacubitril/valsartan is a first-in-class angiotensin receptor-neprilysin inhibitor developed for the treatment of heart failure with reduced ejection fraction. Its benefits are achieved through the inhibition of neprilysin (NEP) and the specific blockade of the angiotensin receptor AT1. The many peptides metabolized by NEP suggest multifaceted potential consequences of its inhibition. We sought to evaluate the short-term changes in serum endorphin (EP) values and their relation with patients' p…

Food as medicine in psychiatric care: Which profession should be responsible for imparting knowledge and use of omega-3 fatty acids in psychiatry

2011

Accepted version of an article in Complementary Therapies in Clinical Practice, 17 (2011), 107-112. Also available from the publisher: http://dx.doi.org/10.1016/j.ctcp.2010.08.001 The effect of omega-3 fatty acids on depression is well documented. The purpose of this study was to determine if and how food is used as medicine in psychiatric care, especially how omega-3 fatty acids are used as a supplement in the treatment of depression. This is a pilot study with a qualitative design using questionnaires and interviews among nursing students, tutor nurses and psychiatrists. Three main categories emerged: 1. Nutrition is considered important but few evaluations are made. 2. There was a lack o…

Mirror training therapy is a promising tool to initiate neural plasticity and facilitate the recovery process of motor skills after diseases such as stroke or hemiparesis by improving the intermanual transfer of fine motor skills in healthy people as well as in patients. This study evaluated whether these augmented performance improvements by mirror visual feedback (MVF) could be used for learning a sport-specific skill and if the effects are modulated by skill level. A sample of 39 young, healthy, and experienced basketball and handball players and 41 novices performed a stationary basketball dribble task at a mirror box in a standing position and received either MVF or direct feedback. Af…

Simulation for training in sinus floor elevation: new surgical bench model

2011

Objectives: to describe a bench model (workshop of abilities) for sinus floor elevation (SFE) training that simulates the surgical environment and to assess its effectiveness in terms of trainees’ perception. Study design: thirty-six randomly selected postgraduate students entered this cross-sectional pilot study and asked to fill in an anonymous, self-applied, 12-item questionnaire about a SFE workshop that included a study guide containing the workshop’s details, supervised practice on a simulated surgical environment, and assessment by means of specific check-lists. Results: Thirtiy-six fresh sheep heads were prepared to allow access to the buccal vestible. Using the facial tuber, third …
