Smartphone single-snapshot mapping of skin chromophores

2016

Suitability of smartphone for single-snapshot mapping of skin melanin, oxy-hemoglobin and deoxy-hemoglobin under 3-wavelengths illumination was demonstrated. Simultaneous 448-532-659 nm illumination was provided by a portable laser-based prototype.

American College of Cardiology/ European Society of Cardiology international study of angiographic data compression phase III. Measurement of image q…

2000

Objectives We sought to investigate up to which level of Joint Photographic Experts Group (JPEG) data compression the perceived image quality and the detection of diagnostic features remain equivalent to the quality and detectability found in uncompressed coronary angiograms. Background Digital coronary angiograms represent an enormous amount of data and therefore require costly computerized communication and archiving systems. Earlier studies on the viability of medical image compression were not fully conclusive. Methods Twenty-one raters evaluated sets of 91 cine runs. Uncompressed and compressed versions of the images were presented side by side on one monitor, and image quality differe…

AB1299-HPR THE RHEUMA-VOR APP: OPTIMIZING THE EARLY DIAGNOSIS OF RHEUMATIC DISEASES

2020

Background:The proof-of-concept network study “Rheuma-VOR” aims to improve the quality of rheumatological care through coordinated cooperation. In particular, rheumatic diseases should be diagnosed as early as possible and treated quickly in a targeted manner [3]. Smartphone apps have a potential to improve the management of chronic diseases. For example, they can be used to provide health information, or to offer self-monitoring and self-screening options [1, 2].Objectives:The Rheuma-VOR Screening-App study examines whether a smartphone-based app can increase the detection rate of the three most common chronic inflammatory rheumatic diseases: rheumatoid arthritis, psoriatic arthritis and s…

Die rechnergestützte Diabeteseinstellung

1985

Blood glucose self-monitoring is essential to stabilize diabetes on a normoglycemic level. But often patients do not find the correct insulin adaptation. Therefore, we developed a computerized system which adapts insulin doses using a control matrix. During a first in-patient period we had a remarkable blood glucose normalization and stabilization.

Critical Appraisal of Scientific Articles

2009

Despite the increasing number of scientific publications, many physicians find themselves with less and less time to read what others have written. Selection, reading, and critical appraisal of publications is, however, necessary to stay up to date in one’s field. This is also demanded by the precepts of evidence-based medicine (1, 2). Besides the medical content of a publication, its interpretation and evaluation also require understanding of the statistical methodology. Sadly, not even in science are all terms always used correctly. The word "significance," for example, has been overused because significant (or positive) results are easier to get published (3, 4). The aim of this article …

Spectral decomposition of RR-variability obtained by an open loop parametric model for the diagnosis of neuromediate syncope

2002

The role of the cardiovascular regulatory mechanism in patients with neuromediate syncope (NS) is poorly understood. The aim of this study was to accomplish continuous non-invasive analysis of the baroreflex mechanism in patients during a head-tip tilt-table test (HTT) using an open-loop autoregressive model with exogenous input. The model describes the causal dependence of the RR interval on the systolic arterial pressure (SAP) variability. Thus, RR variability results as the linear composition of SAP-dependent (Pdep) and SAP-independent parts of the RR power (P). Further, the model allows the estimation of the baroreflex gain using the modulus of the transfer function (G) from SAP to RR i…

Digital health interventions for children with ADHD

2020

Attention deficit hyperactivity disorder (ADHD) is a childhood-onset disorder characterised by a persistent pattern of symptoms of inappropriate and impaired inattention, hyperactivity, or impulsivity, with difficulties often continuing into adulthood.1 It is estimated to affect 37·1 million children and young people (aged ≤20 years) worldwide.2 Although multiple ADHD treatments are available and widely used (eg, evidence-based behaviour therapy, medications, or a combination of both),3,4 their effectiveness has been questioned because they might not fully address the needs of many children with ADHD. Barriers to evidence-based treatment for ADHD include misconceptions and stigma, time, and…

Systemic Review: Ozone: A Potential New Chemotherapy

2021

In the last sixty years, publications in reputed journals have shown the preclinical positive effect of ozone gas in cancer cells. However, the translation of these results into clinical practice is far away from success. A comprehensive approach is necessary for this, and oncologists and researchers need guidance from medical specialists with in-depth knowledge of ozone in medicine. In this article, we review the evidence around this question and suggest different potential research lines to those interested in this exciting field.

Synchronization index for quantifying nonlinear causal coupling between RR interval and systolic arterial pressure after myocardial infarction

2002

The analysis of nonlinear couplings among cardiovascular variability series can improve the knowledge of the cardioregulatory mechanism and help to understand how it can be affected by pathologies. In this study, the influences of acute myocardial infarction (AMI) on the causal relationships between the heart period and the arterial pressure were investigated by a nonlinear dynamic approach based on the corrected cross-conditional entropy. Whereas the global synchronization index did not differentiate the post-AMI patients from the young and old control groups, the causal indexes evidenced the impairment of the baroreflex control and showed an increase of the mechanical driving of the RR in…
